DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
[0028]
In FIG. 2, 1 is a Y table that moves in the Y direction by the rotation of the Y-axis motor 2, and 3 is a result of moving in the X direction on the Y table 1 by the rotation of the X-axis motor 4. The printed circuit board 6 on which the chip-like electronic component 5 (hereinafter referred to as chip component or component) is mounted is fixed and mounted on a fixing means (not shown).
[0029]
Reference numeral 7 denotes a supply table, on which a number of component supply devices 8 for supplying chip components 5 are arranged. Reference numeral 9 denotes a supply table drive motor. When the ball screw shaft 10 is rotated, the supply table 7 is guided to the linear guide 12 via a nut 11 which is screwed into the ball screw shaft 10 and fixed to the supply table 7. Move in the X direction. Reference numeral 13 denotes a rotary table that rotates intermittently. On the outer edge of the table 13, mounting heads 15 having a plurality of suction nozzles 14 are arranged at equal intervals according to the intermittent pitch.
[0030]
I is a suction station which is a stop position of the mounting head 15 where the suction nozzle 14 picks up and picks up the component 5 from the supply device 8 by intermittent rotation of the rotary table 13, and the suction nozzle 14 picks up the component 5 at the suction station I. To do.
[0031]
Reference numeral 16 denotes a component recognition device that recognizes the position shift of the component 5 attracted by the suction nozzle 14 by imaging the lower surface of the component 5 with a camera in a predetermined visual field range and recognizing the imaged screen. Is provided.
[0032]
The position where the mounting head 15 next to the recognition station II stops is the angle correction station III, and the angle amount for correcting the angular position deviation of the chip component 5 due to the recognition result of the recognition device 16 is added to the predetermined angle amount. The head rotating device 17 rotates the mounting head 15 in the θ direction by the angle amount. The θ direction is a direction that rotates around the axis of the nozzle 14 extending in the vertical direction.
[0033]
The next stop position next to the angle correction station III is the mounting station IV, and the component 5 to be sucked by the suction nozzle 14 of the station IV is mounted on the substrate 6 by the lowering of the mounting head 15.
[0034]
Next, the component supply device 8 will be described with reference to FIG.
[0035]
As shown in FIG. 2, the component supply device 8 is made narrow in the moving direction, that is, the arrangement direction of the supply stand 7 of the electronic component automatic mounting device, and as many devices 8 as possible are arranged. Yes. In this way, by narrowing the width and arranging a large number of devices 8, the moving distance of the supply base 7 is made as short as possible.
[0036]
The component supply device 8 is provided with a storage case 23 for storing the chip-shaped electronic component 5 in a bulk shape (in the form of roses) so that it cannot be easily removed. A hole into which the member 24 is inserted is formed so that the chip component 5 is introduced into the cylindrical member 24 by falling under its own weight. The chip component 5 housed (stored) in the case 23 is small, and for example, there are cases in which two long sides have a rectangular parallelepiped shape having a size of 1.6 mm × 0.8 mm. Tens of thousands of 5 are stored.
[0037]
The chip part 5 dropped in the cylindrical member 24 is placed on a rotating flat belt 25 and sent to the left in FIG. 3 by the belt 25. The belt 25 is intermittently rotated by driving the ratchet mechanism, and is vacuum-sucked by the lowering of the suction nozzle 14 when the component 5 is supplied to a predetermined component supply position.
[0038]
As described above, the storage case 23 is narrow in the depth direction of the paper surface of FIG. 3, which is the direction in which the component supply device 8 is disposed, and has a rectangular shape as viewed from above in the left-right direction of FIG. The shape of the inner surface of the container (case) in the horizontal plane is also rectangular. Further, the narrow inner wall 26 (see FIG. 9) of the case 23 is vertically formed from the upper part to a predetermined height (that is, when the component supply device 8 is mounted on the supply table 7, the case 23 is vertical). .) The wider inner wall 22 (see FIG. 9) of the case 23 is also formed vertically.
[0039]
The upper portion of the storage case 23 is an opening 27, and the opening 27 is covered with an upper lid 28 as an opening / closing member. Inside the storage case 23, the chip part 5 is held by its own weight, and a restraining plate 29 as a restraining member that prevents the chip part 5 from colliding with each other due to the movement of the supply base 7 to be worn or damaged can be moved up and down. Has been inserted.
[0040]
The shape of the holding plate 29 is a substantially rectangular parallelepiped shape in accordance with the shape of the inner surface of the storage case 23, and the gap between the inner wall 22, 26 (see FIGS. 1 and 9) of the case 23 is as small as possible, and the chip component 5 is held by the holding plate 29. And the inner walls 22 and 26 so as not to protrude upward. Further, since the holding plate 29 has a rectangular parallelepiped shape, the lower surface 38 is a plane perpendicular to the side surface, and the inner walls 22 and 26 of the case 23 are vertical, thereby holding the chip component 5 in the case 23. In the state, this lower surface is horizontal. In addition, since the supply base 7 behaves so as to move and stop at a distance of about 10 mm in 0.1 seconds, the top surface of the chip component 5 in a loose state is accumulated horizontally by such vibration. Since the lower surface of the holding plate 29 is horizontal, the gap is not formed and the chip component 5 is effectively prevented from being ramped up. If the lower surface of the restraining plate 29 is a surface other than a horizontal plane, the upper surface of the chip component 5 is approached horizontally by the weight of the restraining plate 29, so that there is a gap, and the component 5 jumps in the gap. As a result, the wear and breakage of the component 5 cannot be sufficiently prevented.
[0041]
As described above, the gap between the side surface of the holding plate 29 and the inner walls 22 and 26 of the case 23 needs to be made small so that the chip component 5 does not pop out. However, the holding plate 29 is not inclined. It is necessary to make it as small as possible so that it can be smoothly raised and lowered by being guided by the inner wall 26 of the case 23. However, since it is difficult in processing to make the gap too small, the suppression plate 29 is prevented from being inclined by taking the thickness (height direction) of the suppression plate 23 to some extent. However, if the thickness is excessively large, the capacity of the storage case 23 becomes small or the case 23 becomes too large. Therefore, it is necessary to consider the thickness.
[0042]
Further, since the side surface 37 that slides with the inner wall 26 is relatively narrow, the gap can be reduced. However, since the side surface 31 of the holding plate 29 that slides with respect to the inner wall 22 has a wide sliding surface, the gap is kept small and constant. It is difficult. Further, since the side surface 31 hits the inner wall 22 due to the movement and stop operation of the supply base 7, if the gap is large, it is easy to be damaged. Comes out. For this reason, as shown in FIGS. 10 and 11, the side surface 31 is provided with protrusions 40 extending vertically (in the direction in which the holding plate 29 moves up and down) at two locations. By reducing the size of the protrusion 40 and the inner wall 22, the restraining plate 29 and the inner wall 22 are fitted so as to move smoothly and without rattling. However, it is necessary to set a gap between the side wall 31 and the inner wall 22 other than the protrusion 40 so that the chip component 5 cannot pass. Although the holding plate 29 is described as having a substantially rectangular parallelepiped shape, the upper surface may not be a part of the rectangular parallelepiped.
[0043]
The inner wall 26 of the storage case 23 is inclined at a predetermined angle from the vertical below, and the chip component 5 slides down on the inclined surface and is introduced into the opening of the cylindrical member 24 described above. The holding plate 29 can be lowered to a position where the inner wall 26 of the case 23 is inclined from the vertical, and cannot be lowered below this.
[0044]
The material of the storage case 23 and the holding plate 29 is resin, and it is desirable that they are the same material so that the thermal expansion coefficient is the same. Further, the side wall of the storage case 23 may be transparent or translucent so that the state of the holding plate 29 and the amount of the chip component 5 can be understood. If at least the side surface of the case 23 of the inner wall 22 is semi-transparent or transparent, confirmation becomes easy.
[0045]
Next, a mechanism for replenishing the chip component 5 into the storage case 23 will be described with reference to FIG.
[0046]
A string 30 as a flexible linear body is attached to the central portion of the upper surface of the holding plate 29, and the other end is connected to a slide plate 32 as a traction member. The slide plate 32 is attached so as to be reciprocally movable in a horizontal direction (arrow direction in FIGS. 1 and 4) along a guide groove (not shown) formed on the upper lid 28. The restraining plate 29 is moved up in the case 23 by the movement of the slide plate 32 in the arrow direction so as to be in close contact with the upper lid 28.
[0047]
The right end surface of the upper lid 28 in FIG. 1 protrudes in a dogleg shape, and the protruding portion 34 is fitted into a notch 33 in the wall of the case 23 so that there is no gap in the case 23.
[0048]
The projecting length of the projecting portion 34 is the same as the thickness of the restraining plate 29, and the restraining plate 29 ascends to the corner portion (perpendicular) of the upper lid 28 as shown in FIG. It is made to fit, and both are united. The inside of the protruding portion 34 with which one end of the holding plate 29 is engaged is the engaged portion.
[0049]
A guide portion (not shown) is formed in the opening 27 at the upper end of the storage case 23 when the upper lid 28 protrudes from the notch 33 and slides, and the slide plate 32 is moved from the state of FIG. 4 to the state of FIG. Even after being moved, the holding plate 29 and the upper lid 28 slide and move as shown in FIG.
[0050]
Further, the movement guide portion of the upper lid 28 also serves as a guide portion that can be slid and moved by fitting the outlet side of the bulk case 36 containing the chip component 5 for replenishment, and by moving the upper lid 28 by an appropriate amount, The opening 27 of the case 23 and the opening of the outlet of the case 36 can be communicated with each other without leaking the chip component 5 outside.
[0051]
Since it can do in this way, it is also possible to return the chip component 5 in the storage case 23 to the bulk case 36 by inverting the component supply device 8 removed from the supply base 7. The sliding movement of the upper lid 28 may be regulated by a stopper so as to stop at a position where the bulk case 36 is fitted.
[0052]
Hereinafter, the replenishment operation of the chip component 5 will be described.
[0053]
With the supply table 7 stopped at a predetermined position and the component supply device 8 attached to the supply table 7, the slide plate 32 of the storage case 23 of the component supply device 8 to be refilled by the operator is moved in the direction of the arrow in FIG. As shown in FIG. 6, the holding plate 29 connected to the string 30 is pulled and lifted as shown in FIG. 5, and is brought into close contact with the upper lid 28 as shown in FIG.
[0054]
At the time of this rise, the side face 38 of the holding plate 29 and the protrusion 40 on the side face 31 rise while maintaining a horizontal state while being guided by the inner walls 22 and 26.
[0055]
Further, when the slide plate 32 is slid and moved as a series of operations, the holding plate 29 and the upper lid 28 are integrally slid on the opening 27 and stopped by restriction of a stopper (not shown) after moving a predetermined distance. In this embodiment, the holding plate 29 is moved by being pulled by the string 30. However, the upper lid 28 may be moved by pushing the protruding portion 34 by the holding plate 29, and the slide plate 32 may be moved by the upper lid. You may make it move 28 directly.
[0056]
The bulk case 36 in which the chip component 5 is sealed is fitted in the opening 27 thus opened, as described above, and the shutter (not shown) of the bulk case 36 is opened to flow the chip component 5 into the storage case 23. It is.
[0057]
Next, the bulk case 36 is removed, the upper cover 28 is moved in the direction of the arrow as shown in FIG. 7, the opening 27 is closed, and the slide plate 32 is moved leftward as shown in FIG. While being guided by the inner wall 26 until it is placed on the chip component 5, it is lowered while keeping the lower surface horizontal.
[0058]
In this state, the automatic operation of the electronic component automatic mounting apparatus is performed by operating an operation unit (not shown).
[0059]
First, the chip component 5 in the case 23 is conveyed on the belt 25 to a position where the suction nozzle 14 can be sucked by driving the belt 25 and the cylindrical member 24.
[0060]
Next, the supply table 7 is moved so that the component supply device 8 that supplies the desired chip component 5 stops at the suction position of the suction nozzle 14. At the time of this movement and stop, since the restraint plate 29 presses the bulk (bulk) chip component 5 with which it is integrated, it is possible to suppress wear due to collision with each other.
[0061]
Next, after the suction nozzle 14 picks up the component 5, the rotary table 13 rotates intermittently and the mounting head 15 reaches the next station. At this time, at the suction station I, the next component 5 is sucked in the same manner.
[0062]
Next, the position shift of the component 5 is recognized by the recognition device 16, and thereafter the angular position and the position in the XY direction are corrected, and the component 5 is mounted on the printed circuit board at the mounting station IV.
[0063]
Each time the component 5 is sucked in this way, the supply base 7 is moved and stopped at a high speed, and the integrated state of the components 5 in the storage case 23 is substantially horizontal on the top surface, Thus, there is almost no gap even when the supply table 7 moves.
[0064]
In this way, when the parts 5 in the storage case 23 are gradually reduced, the holding plate 29 is lowered while holding the parts 5 with the lower surface kept horizontal.
[0065]
The component 5 can be supplied to the storage case 23 even if the component supply device 8 is attached to the supply table 7, but can also be supplied in the same manner even when it is detached.
[0066]
In the first embodiment, the string 30 is directly connected to the holding plate 29. However, a member such as a spherical object is provided in the middle of the string 30, and this member is engaged with the upper lid 28 so that the upper lid 28 is engaged. The holding plate 29 may be integrated and moved. In this way, the holding plate 29 can be moved without pressing the protruding portion 34.
[0067]
Next, a second embodiment will be described.
[0068]
The structure of the component supply device 8 itself is substantially the same as that of the first embodiment, and the difference is the structure of the holding plate 41 and the upper lid 42 that move up and down in the storage case 23 shown in FIG.
[0069]
That is, the holding plate 41 has the same structure as the holding plate 29 and the side and bottom surfaces of the holding plate 29 of the first embodiment, and has a function of holding the chip component 5 in the storage case 23 and preventing its rampage and has a wide side. The protrusion 40 is similarly formed. Therefore, as the number of parts 5 decreases, the lower surface is kept horizontal and the parts are lowered by their own weight while holding the parts.
[0070]
A different point is a mechanism for removing the holding plate 41 as a holding member and opening the upper lid 42 as an opening / closing member when the component 5 is replenished. In the second embodiment, a jig as an opening / closing auxiliary member That is, the rod 43 is used. The jig bar 43 functions as a fixing means for fixing the holding plate 41 to the upper lid 42 and as a fixing releasing means for releasing the fixing.
[0071]
The upper lid 42 has the same structure as the upper lid 28 except that a hole that allows the jig bar 43 to pass therethrough is formed and that the slide plate 29 is not guided.
[0072]
In addition, an engagement piece 44 that protrudes in a horizontally opposed direction protrudes from the lower end portion of the jig bar 43, and a fitting hole into which the engagement piece 44 is fitted above the holding plate 41. 45 is drilled. As shown in detail in FIG. 13, the fitting hole 45 has a shape in which the engagement piece 44 can be inserted only in the opening, the inside is circular as viewed from above, and the engagement piece 44 can rotate. When it is rotated, it is restricted by the ceiling surface and is prevented from coming off, and the holding plate 41 is lifted by lifting the jig bar 43. Inside the fitting hole 45, there is provided a stopper 46 for restricting rotation when the inserted engagement piece 44 is rotated and rotated 90 degrees.
[0073]
The replenishment operation of the chip component 5 in the second embodiment will be described with reference to FIGS.
[0074]
First, when the chip component 5 is not in the storage case 23 or is loaded only up to the portion where the inner wall 26 is inclined, the holding plate 41 is inclined from the vertical as shown in FIG. It stops at the site that changes to.
[0075]
In this state, the operator inserts the jig bar 43 into the case 23 through the hole of the upper lid 28, and inserts the engagement piece 44 at the tip into the fitting hole 45 of the holding plate 41.
[0076]
Next, the jig bar 43 is rotated in the fitting hole 45 as shown in FIG.
[0077]
Next, by pulling up the jig bar 43, the holding plate 41 is brought into close contact with the upper lid 42 as shown in FIG. 16, and in this state, the upper lid 42 and the holding plate 41 are moved in the direction of the arrow as shown in FIG. The opening 27 is opened by sliding.
[0078]
Next, the supply port of the bulk case 36 is slid into the opening 27 and fitted as shown in FIG. 16, and a shutter (not shown) is opened to allow the chip component 5 to flow into the storage case 23 for replenishment. If the case 23 is not full with only one bulk case 36, a plurality of bulk cases 36 may be used. When working such as attaching the bulk case 36, the holding plate 41 is placed on the side wall of the case 23, and the holding plate 41 does not fall even if the hand is released from the jig bar 43. Absent.
[0079]
Next, the bulk case 36 is removed, and as shown in FIG. 17, the jig bar 43 is moved in the direction of the arrow to close the opening 27, the jig bar 43 is rotated in the opposite direction, and the engagement piece 44 is fitted. Remove from hole 45 and remove.
[0080]
As a result, as shown in FIG. 18, the holding plate 41 is kept in a horizontal state and comes to contact with the chip component 5 that has been dropped and replenished, and stops while holding the component 5.
[0081]
In the second embodiment, the holding plate 41 moves by pressing the protruding portion 34, but the jig bar 43 can be used as both the holding plate 41 and the upper lid 42 even if the holding plate 41 is not in contact with the protruding portion 34. Can also be moved.
[0082]
The following automatic driving operation is the same as that of the first embodiment.
[0083]
Next, a third embodiment will be described.
[0084]
In the first embodiment, since the slide plate 32 or the holding plate 29 is not fixed to the upper lid 28, when the upper lid 28 is closed as shown in FIG. The restraining plate 29 may start dropping, and the restraining plate 29 hits the upper end portion of the wall of the storage case 51 and the direction perpendicular to the inner wall 26 (the component supply device 50 is moved). When attached to the supply stand 7, it may descend while maintaining an oblique posture with respect to the horizontal direction. In order to avoid such a situation, it is difficult to hold the slide plate 32 so that the position with respect to the upper lid 28 does not shift until the upper lid 28 is completely closed. The third embodiment is for solving the problems of the first embodiment.
[0085]
The structure of the component supply device 50 itself is substantially the same as that of the component supply device 8 of the first embodiment, and the same structure will be described with the same reference numerals.
[0086]
As shown in FIGS. 19 to 25, the component supply apparatus 50 is provided with a storage case 51 similar to that of the first embodiment, and chip components are stacked and stored in a bulk shape.

Since the fixed state is maintained in this way, if the one end engaging hook 66 is engaged with the engaging pin 65, the operator places his / her finger at an appropriate position on the upper lid 59 without moving the slide plate 58. The opening 27 can also be opened by hanging.
[0100]
Next, after the filling of the parts 5 is completed, the bulk case 36 is removed, the slide plate 58 or the upper lid 59 itself is moved to the left side, and the opening 27 is closed.
[0101]
As shown in FIG. 24, when the opening 27 is completely closed and the holding plate 52 is in a position where it does not catch on the side wall 70, the locking lever 72 swings counterclockwise, and the bearing 74 is engaged. By pushing up 67, the engagement hook 66 is disengaged from the engagement pin 65.
[0102]
As a result, as shown in FIG. 25, the holding plate 52 maintains a posture in which the bottom surface is perpendicular to the side wall 70 (or a horizontal posture when the component supply device 50 is attached to the supply stand 7). It descends by its own weight and is placed on the loaded component 5.
[0103]
