Description

The present invention relates to a barrel plating apparatus, and more particularly to a barrel plating apparatus using an inclined barrel.

When plating on a small object to be plated such as a chip-type electronic component, a barrel plating method that can be processed in a large amount at a low cost is widely used. The barrel plating method contains a large number of objects to be plated and agitation auxiliary materials in a container called a barrel, and stirs the object to be plated by rotating the barrel completely or partially in the plating solution. -It is a method of plating on the surface of an object to be plated while mixing. Generally, there are two types of barrel rotation methods: horizontal (the barrel rotation axis is horizontal) and inclined (the barrel rotation axis is inclined).
(1)

Generally, the following members are used as a stirring aid in plating, and are added in an appropriate amount according to each plating condition.
(1) Stirrer auxiliary material element floating restraint ball in electroless plating, sticking restraint media, (sacrificial metal media: contact plating)
(2) Stirrer auxiliary element in electrolytic plating, float prevention ball, sticking suppression media, conductive media

Patent Document 1 discloses a barrel plating apparatus that performs a plating process while horizontally supporting a barrel. Both side surfaces of the barrel are open, and a workpiece can be taken in and out, and a mechanism for raising and lowering the barrel and a mechanism for taking out the subject to be plated by tilting when the barrel is raised are provided. The plating process is performed by lowering the barrel to the plating tank, immersing the barrel in a plating solution, and then horizontally rotating the barrel via a transmission mechanism from a driving device provided outside the barrel plating apparatus. The advantage of this apparatus is that the stirring performance is better than that of a tilt-rotating barrel by horizontally rotating the barrel. On the other hand, a drawback is that a mechanism such as raising and lowering and tilting of the barrel is necessary, and a large-sized automatic plating apparatus is a prerequisite.

Patent Literature 2 discloses a barrel plating apparatus that performs plating by supporting a barrel in an inclined state. An opening is provided on one side of the barrel to allow loading and unloading of objects to be plated, and a driving gear for rotating the barrel is provided on the side opposite to the opening, and the barrel is driven by rotation by a drive motor provided at the top. A transmission mechanism for transmitting to the gear and rotating the barrel is provided. In order to perform the plating treatment, the barrel apparatus is lowered to the plating treatment tank, the barrel is immersed in the plating solution, and then the barrel is rotated in an inclined state. The advantage of this device is that it has a mechanism for supporting the barrel only on one side, and a structure that allows easy removal of the barrel can be easily adopted. On the other hand, since the barrel is cantilevered, the structure for securing the load resistance becomes large or the inclination angle needs to be limited.

  In general, the barrel plating apparatus has a structure in which a lid for taking in and out the object to be plated is provided on the barrel in order to prevent spillage of the object to be plated. However, in order to simplify and automate the plating operation, an open barrel as shown in the prior art has been devised. However, when performing plating using these barrel plating apparatuses, there are the following problems.

  As for electronic components that are subject to plating, not only miniaturization but also diversification of component shapes, electrode shapes, and electrode metals are progressing, and accordingly, electroless plating is adopted instead of electrolytic plating. More and more are being done. In general, electroless plating has a shorter plating solution life than electrolytic plating. Also, in order to extend the life of the liquid, it is necessary to provide a large-scale regenerator or perform advanced liquid management. In either case, it becomes a factor that increases the cost of electroless plating as compared with electrolytic plating.

The barrel plating apparatus shown in the prior art has a mechanism for rotating and stirring the barrel by immersing the barrel portion in a plating solution. For this reason, the structure which needs to be immersed in a plating solution contains a drive part, the support part, etc. other than a barrel main body. In particular, in the opening / tilting type (Patent Document 2), since the barrel is held only on one side, there is a problem that the structure becomes large because it is necessary to increase the load resistance of the holding and the support portion. As a result, the plating tank is increased in size, and an excessive amount of plating solution is used for immersing the barrel.

With respect to the diversification of the electrode metal described above, there are an increasing number of parts that perform multilayer electrode formation. In general, Ni, Cu, Sn, Pd, Au, or the like is used, and plating of a multilayer electrode in which two or three kinds of these metals are combined is performed. The barrel plating apparatus disclosed in Patent Document 1 is considered difficult to apply unless it is a mechanized automatic plating apparatus. However, in such an automated plating apparatus, handling to the barrel main body (for example, to the object to be plated) The barrel body comes out of the plating equipment, such as replacing the barrel body to apply the matched barrel specifications, and adding an appropriate amount of agitation auxiliary material to the barrel according to the plating conditions. It is constrained at the time. Therefore, there is a problem that handling is difficult.

In the barrel plating apparatus disclosed in Patent Document 2, when handling the barrel, it is necessary to lift not only the barrel body but also the entire barrel plating apparatus including the drive motor and the like. For this reason, when the size of the apparatus is increased in order to increase productivity, there is a possibility that the weight that can be easily handled manually is exceeded. Moreover, since the drive mechanism for rotating a barrel is located in the bottom part of a barrel and is immersed in the plating solution, there exists a fault that the size of a plating tank becomes large. Further, in this case, as in Patent Document 1, the barrel body cannot be handled unless the entire barrel plating apparatus is lifted from the plating tank.

Japanese Patent Application Laid-Open No. 60-77995 Japanese Patent No. 3650081

Accordingly, an object of the present invention is to provide a barrel plating apparatus that can be easily handled with respect to a barrel.

In order to achieve the above object, the present invention comprises a cylindrical barrel having an opening on one end side in the axial direction of the body part, and in a state where the other end side in the axial direction of the body part is inclined downward, In a barrel plating apparatus for rotating an axis line as a central axis and plating an object to be plated placed in the barrel, an apparatus frame, a flange formed around an opening of the barrel, and the apparatus frame An annular turntable that is rotatably held in a state inclined at a predetermined angle with respect to a horizontal plane, can be inserted through the barrel portion of the barrel, and supports the lower surface of the flange portion, and the flange portion of the barrel is attached to the turntable. A plating tank storing a plating solution for immersing the other axial end of the barrel body in an inclined state, and a rotation that is provided outside the plating tank and rotates the rotating plate. Drive mechanism Provides a barrel plating apparatus characterized by comprising a.

  In the barrel plating apparatus of the present invention, only the lower part of the barrel is immersed in the plating solution, and the part where the barrel is attached to the rotation drive mechanism and the rotation drive mechanism itself are outside the plating tank. Therefore, as long as the rotation of the barrel is stopped (even if there is a safety measure, it can be rotated), it is possible to easily supply a stirring aid used for the plating process in the barrel at any time. Moreover, the removal | desorption of a barrel can be easily implemented only by inserting / removing a barrel with respect to a turntable irrespective of the state of a plating tank. By setting it as the said structure, the magnitude | size of the plating tank for immersing a barrel can be match | combined with the magnitude | size of a barrel. Unlike the conventional method, since it is not necessary to immerse the rotary drive mechanism of the barrel in the plating tank, the size of the plating tank can be reduced and the amount of the plating solution can be reduced. Since the barrel itself does not have a drive motor or a drive transmission unit and is constituted only by the barrel, the barrel is light in weight and easy to handle by hand such as removal and transfer of the barrel.

The rotating disk preferably has a configuration in which the rotating frame is supported rotatably by the support frame provided at a plurality of locations in the circumferential direction while maintaining the inclined posture. By supporting the rotating plate with a plurality of support rollers, even if the weight of the barrel is applied to the rotating disk, the rotating plate can be rotated smoothly while maintaining a stable inclined posture.

The turntable preferably has a support plate portion that supports the lower surface of the flange portion of the barrel and a guide portion that supports the outer periphery of the body portion in the vicinity of the flange portion. A structure in which the rotating disk supports only the lower surface of the flange portion may be used. However, in addition to the load in the vertical direction, a downward rotating moment acts on the barrel with the horizontal axis as a fulcrum, and stress concentrates on the flange portion. Therefore, by providing a guide part that supports the outer periphery of the barrel part of the barrel on the rotating disk and supporting a part of the rotational moment applied to the barrel by this guide part, stress concentration on the flange part can be alleviated.

  The rotational drive mechanism includes a driven pulley provided on the outer peripheral portion of the rotating disk, a driving motor, a driving pulley attached to the motor, a belt wound between the driving pulley and the driven pulley, It is good also as a structure provided with. A gear mechanism may be used as a transmission mechanism for transmitting the rotation of the motor to the rotating disk. However, when a belt transmission mechanism is used, the degree of freedom of motor arrangement is improved.

  Two rail grooves are formed in a circular shape on the outer peripheral surface of the rotating disk, the support roller includes a pair of wheel portions that engage with the rail grooves of the rotating disk, and the rotation drive mechanism is provided on the outer peripheral surface of the rotating disk. A driven pulley provided between the rail grooves, a driving motor, a driving pulley attached to the motor, and a belt wound between the driving pulley and the driven pulley. It is good also as a structure inserted between a pair of wheel parts, without contacting a support roller. In this case, since the support mechanism and the rotation transmission mechanism of the rotating disk can be arranged so as to overlap in the axial direction, the axial length of the rotating disk can be shortened, and hence the axial length of the barrel can be shortened. Moreover, since each support roller is provided with a pair of wheel part engaged with two rail grooves, it can support the rotational moment added to a turntable more stably.

  It is desirable that the plating tank has a shape opened upward so as to cover the lower side of the other axial end side of the barrel body. When the barrel is tilted and rotated, the object to be plated and the stirring auxiliary material housed inside gather at the lower corner of the barrel, so the plating solution immerses the object to be plated and the stirring auxiliary material collected at this corner. A sufficient amount is sufficient. Thus, the plating tank is formed in a shape that covers only the portion of the barrel body that is immersed in the plating solution, thereby reducing the size and the amount of the plating solution. Various sensors such as a temperature sensor and a liquid level sensor can be inserted from above the opened plating tank.

According to the present invention, only the lower part of the barrel is immersed in the plating solution, and the part where the barrel is attached to the rotation drive mechanism and the rotation drive mechanism itself are outside the plating tank. Handling such as supply of the stirring aid to be used becomes easy. Further, the barrel can be detached regardless of the state of the plating tank. Since it is not necessary to immerse in the plating tank up to the rotational drive mechanism of the barrel, the size of the plating tank can be reduced, and an unnecessary plating solution is not used for immersing the barrel. Since the barrel itself does not have a drive motor or a drive transmission unit, the barrel is lighter and easy to handle manually, such as removing and transporting the barrel.

It is a side view of the barrel plating apparatus which concerns on 2nd Embodiment of this invention. It is a front view of the barrel plating apparatus shown in FIG. FIG. 6 is a cross-sectional view taken along line VI-VI in FIG. 5.

Embodiment 1
A barrel plating apparatus according to a first embodiment of the present invention will be described with reference to FIGS. The barrel plating apparatus includes an apparatus frame 1, a hot water heating tank 5, a plating tank 10, a barrel 20, a rotating plate 30, a driving motor 40, and the like.

A hot water heating tank 5 is installed in the apparatus frame 1. Warm water is stored in the warm water heating tank 5, and the warm water heater 6 can adjust the warm water to a predetermined temperature. A predetermined amount of the plating solution P is stored in the plating tank 10, and the plating solution P is indirectly heated by immersing the plating tank 10 in the hot water in the hot water heating tank 5, and adjusted to a predetermined plating treatment temperature. ing. The plating tank 10 has a truncated truncated cone shape that covers a lower portion of the barrel 20 described later and opens upward so as not to interfere with the barrel 20. A drainage pipe 11 for discharging the plating solution P is connected to the bottom of the plating tank 10.

A water supply pipe 7 to the hot water heating tank 5 and a water supply pipe 12 to the plating tank 10 are installed on the ceiling portion of the apparatus frame 1. Further, a temperature sensor / liquid level sensor 8 for detecting the temperature of the hot water is suspended from the apparatus frame 1 toward the hot water heating tank 5, and the temperature of the plating solution P is detected from the apparatus frame 1 into the plating tank 10. A temperature sensor / liquid level sensor 13 is vertically provided.

As shown in FIG. 3, the barrel 20 is provided with a hexagonal cylindrical body portion 21, an opening portion 22 on one end side in the axial direction of the body portion 21, and a disc-shaped flange portion 23 around the opening portion 22. And are integrally formed. On the other end side in the axial direction of the body portion 21, a tapered portion 24 tapered toward the tip end and a flat bottom portion 25 at the tip end are formed. On the other end side in the axial direction of the body portion 21, a communication portion 26 made of a mesh or the like that connects the inside and outside of the body portion 21 is provided.

On the front surface of the apparatus frame 1, an inclined plate 2 inclined by about 45 ° with respect to a horizontal plane is fixed. On the surface side of the inclined plate 2, a cover member 3 is fixed in parallel to the inclined plate 2 with a space therebetween. The inclined plate 2 and the cover member 3 are formed with holes 2a and 3a, respectively, and a plurality of support rollers 4 are rotatably mounted around the holes while being supported at both ends by the inclined plate 2 and the cover member 3. It has been. In this example, three support rollers 4 are arranged at intervals of 120 °, but the number of support rollers 4 is arbitrary as long as it is three or more. The turntable 30 is supported by these support rollers 4 so as to be rotatable in an inclined state. In this example, the turntable 30 is supported in a state inclined by about 45 ° with respect to the horizontal plane, but the inclination angle can be arbitrarily set within a range of 35 ° to 50 °, for example. As shown in FIG. 3, a center hole 31 is formed in the turntable 30, and a flange-like support plate portion 34 is formed around the upper end portion of the center hole 31. A driven pulley 32 is integrally formed. A separate driven pulley 32 may be fixed to the rotating disk 30. A cylindrical guide portion 33 extending downward is integrally formed at the lower end portion of the turntable 30.

The barrel portion 21 of the barrel 20 is inserted into the central hole 31 of the turntable 30, and the barrel 20 is supported in an inclined state by supporting the lower surface of the flange portion 23 with the upper surface of the support plate portion 34 of the turntable 30. ing. In addition, the barrel 20 can be detachably fixed to the turntable 30 by fastening the flange portion 23 of the barrel 20 and the turntable 30 with a fastener such as a bolt or a clamp. A part of the outer periphery of the barrel portion 21 of the barrel 20 is supported by the inner surface of the central hole 31 of the rotating disk 30 (including the guide portion 33), and can support the rotational moment applied to the barrel 20. With the barrel 20 supported by the turntable 30, the other axial end of the body portion 21 is inserted into the plating tank 10. At this time, the inclination angle of the barrel 20 is set so that the axis of the trunk portion 21 and one slope of the plating tank 10 are parallel and the bottom 25 of the barrel 20 and the opposite slope of the plating tank 10 are parallel. By this, the clearance gap between the barrel 20 and the plating tank 10 can be narrowed, and the waste of the plating solution P can be reduced. In this example, a tapered portion 24 is formed on the bottom side of the barrel 20, and the waste of plating solution can be further reduced by making the tapered portion 24 substantially parallel to the bottom surface of the plating tank 10.

As shown in FIG. 2, two rail grooves 32a are formed on the outer peripheral surface of the driven pulley 32 with an interval in the axial direction, and a pulley groove 32b is formed in the middle of the rail groove 32a. The support roller 4 includes a pair of wheel portions 4a that engage with the rail grooves 32a, and the wheel pulley 4a and thus the turntable 30 are rotatably supported by the wheel portions 4a in an inclined state. A belt 43, which will be described later, is wound around the pulley groove 32b. The belt 43 is inserted between the wheel portions 4a so as not to contact the support roller 4.

  A driving motor 40 is fixed to the lower part of the inclined plate 2 of the apparatus frame 1, and a driving pulley 42 is fixed to a rotating shaft 41 of the motor 40. A belt 43 is wound around the driving pulley 42 and the driven pulley 32 fixed to the rotating disk 30. The motor 40, the drive pulley 42, the driven pulley 32, and the belt 43 constitute a rotational drive mechanism 45 that rotationally drives the barrel 20.

  Here, the operation of the barrel plating apparatus having the above configuration will be described. First, the barrel 20 is inserted into the central hole 31 of the turntable 30 and fixed to the turntable 30. At this time, the lower end of the barrel 20 is immersed in the plating solution P stored in the plating tank 10. The plating solution P is set to a desired temperature by adjusting the temperature of the hot water stored in the hot water heating tank 5. Next, a work (to-be-plated object and a stirring auxiliary material) is thrown in from the opening part 22 of barrel 20 upper part. Then, the driving motor 40 is driven, and the barrel 20 is rotated integrally with the turntable 30 to perform the plating process. After the plating process is completed, the plating solution P is drained through the drain pipe 11 and the flush water is supplied from the water feed pipe 12 to wash the plating tank 10, and then the barrel 20 is taken out from the turntable 30 and the next step. Transport to. In addition, as long as there is no influence on a plating process, you may perform a multiple types of plating process continuously.

  For example, the handling operation to the barrel 20 such as exchanging the barrel 20 for application of the barrel specification according to the object to be plated, or adding an appropriate amount of agitation auxiliary material in the barrel 20 in accordance with the plating processing conditions. May be performed. In the barrel plating apparatus according to the present invention, since the opening portion 22 of the barrel 20 is always open upward, it is easy at any time as long as the rotation of the barrel 20 is stopped (even if there is a safety measure). It is possible to supply a stirring aid or the like into the barrel 20. Moreover, since the removal of the barrel 20 can be easily performed regardless of the state of the plating tank 10 simply by inserting / removing the barrel 20 with respect to the turntable 30, the case of performing plating of a multilayer electrode combining a plurality of metals. But it can be done easily. Thus, the handling location and timing of the barrel 20 are not restricted to the time when the barrel 20 is out of the plating apparatus, and the handling becomes easy. In general, in electroless plating, it is necessary to replace the plating solution P every time. However, since the plating tank 10 only needs to store the plating solution P that immerses the lower end of the barrel 20, a relatively small amount of the plating solution P is required. The plating solution is sufficient, and the cost can be reduced.

Since the barrel 20 is supported in an inclined state as described above, the load applied to the rotating disk 30 increases due to the weight of the barrel 20, but the rotating disk 30 can be stably provided by arranging a plurality of support rollers 4. It can be held, and the runout of the barrel 20 during rotation can be made. This structure can be adopted because the rotation transmission mechanism and barrel load support mechanism are outside the plating tank 10 and do not affect the size of the plating tank 10. At the same time, as a material for the rotation transmission mechanism and the barrel load support mechanism and wear resistance measures, options such as a lubricant can be expanded, and an apparatus can be manufactured effectively and easily.

The effects of the barrel plating apparatus are listed as follows.
(1) Only the barrel can be removed from the top and front of the plating equipment. Since only the barrel can be handled separately from the rotary drive mechanism, the barrel can be significantly reduced in weight compared to the prior art and easy to handle manually.
(2) The opening of the barrel is not in the plating tank and can be involved regardless of the plating process. This means that quality can be checked, plating can be continued, plating solution and media can be replenished during plating during the plating process, and plating quality and plating costs can be reduced. Contribute.
(3) A barrel is attached to a turntable incorporated in the plating apparatus, and the gap between the plating tank wall and the barrel can be regulated structurally. For this reason, even if the gap between the plating tank wall and the barrel is reduced, when the barrel is rotated, the barrel contacts or collides with the plating tank wall, and either or both are not damaged. For this reason, it becomes possible to make a plating tank size small according to the size of a barrel. This makes it possible to minimize the amount of plating solution required to immerse the workpiece.
(4) By placing only the barrel in the plating tank, the plating tank size can be designed smaller than the barrel apparatus including the barrel drive transmission section and the support section as in the prior art. This also leads to reduction of the necessary plating solution.
(5) Since the rotation drive, transmission mechanism and barrel load support mechanism are outside the plating tank and do not come into contact with the plating solution, it is possible to expand the options for materials that can be used for them and lubricants for wear resistance. I can do it. This makes it possible to increase load bearing performance and use inexpensive parts, enabling effective and easy device fabrication.
(6) Although the length of the barrel becomes longer because the barrel is immersed in the plating solution, the design freedom is wide and the rotation mechanism that receives the barrel load is supported at a large diameter and at multiple points. It can cope with an increase in required load capacity.

[Embodiment 2]
4 to 6 show a second embodiment of the barrel plating apparatus according to the present invention. This barrel plating apparatus is an inclined plating apparatus in which a barrel rotating mechanism, a hot water heating tank, and a plating tank are integrated. The elements of the plating apparatus are the same as in the first embodiment, but the hot water heating tank and the plating tank are connected and integrated with the barrel rotation mechanism unit to make the entire inclination angle movable. Portions common to the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 6, a pair of support shafts 2 a are fixed to the left and right sides of the inclined plate 2 of the device frame 1 via a bracket 2 b, and a pair of bearings provided with the support shaft 2 a on the device frame 1. The inclined plate 2 can be tilted up and down with the horizontal axis as a fulcrum by being rotatably supported by 1a. On the inclined plate 2, a hot water heating tank 5, a plating tank 10, a driving motor 40, and the like are fixed. A rotating plate 30 is rotatably attached to the inclined plate 2 via a plurality of support rollers 4, and the barrel 20 can be inserted into and removed from the rotating plate 30. A pair of clamps 35 is provided on the turntable 30, and the flanges 23 of the barrel 20 can be pressed and held on the support plate 34 of the turntable 30 by these clamps 35. One support shaft 2a is connected to a rotary handle 50 provided on the side of the apparatus frame 1 via a transmission mechanism such as a chain. When the handle 50 is turned, the support shaft 2a is rotated, and the hot water heating tank 5, the plating tank 10, the turntable 30 (barrel 20), the driving motor 40, and the like can be integrally tilted. By changing the inclination angle of the inclined plate 2 in accordance with the plating process conditions for each product to be plated, the inclination angle of the barrel 20 mounted on the rotating disk 30 can be arbitrarily changed.

In this embodiment, the hot water heating tank 5 is formed in a cylindrical shape so as to cover the outer periphery of the plating tank 10, and the plating tank 10 is also formed in a cylindrical shape so as to cover the outer periphery of the barrel 20. A heater 6 is attached to the outer periphery of the hot water heating tank 5. As shown in FIG. 4, flexible water supply pipes 7 and 12 are connected to the hot water heating tank 5 and the plating tank 10, respectively, and correspond to the tilting of the hot water heating tank 5 and the plating tank 10.

In the case of the present embodiment, in addition to the same effects as those of the first embodiment, there are the following effects.
(1) By changing the barrel inclination angle arbitrarily (movable range: 30 ° to 55 °, practically effective angle: 35 ° to 50 °), it is possible to set appropriate conditions for each product to be plated.
(2) Since the plating tank surrounds the barrel with a cylindrical shape, the plating solution can be further reduced from the specification of the first embodiment.
(3) Since the plating tank and the barrel are covered with the hot water heating tank, a change in the processing temperature during the plating process can be suppressed.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, a belt transmission mechanism is used to transmit the rotation of the drive motor to the rotating disk, but a chain transmission mechanism or a gear mechanism may be used. In the case of a gear mechanism, the drive gear is fixed to the rotary shaft of the drive motor, the ring gear is fixed instead of the driven pulley on the outer periphery of the rotating disk, and the drive gear and the ring gear are meshed directly or via an idler gear. Good. Also in this case, the axial length of the rotating disk can be shortened by providing the ring gear between the rail grooves.
