[Problems to be solved by the invention]
However, the work of peeling the protective seal from the seal body is not so easy. In particular, when a protective seal is attached to the entire surface of the seal body, it is difficult to peel the thin protective seal. In particular, it was very difficult for a robot to perform such tasks that were difficult even for human tasks.
[0006]
The present invention has been made in view of the above problems, and an object of the present invention is to provide a protective seal peeling device that can effectively peel a protective seal from a seal body.
[0007]
[Means for Solving the Problems]
The present invention relates to a protective seal peeling device for peeling off a protective seal arranged in close contact with the surface of a seal body, the hollow pipe having both ends rotatably supported, and the entire width of the axial direction on the surface of the hollow pipe. Are arranged substantially in a straight line, communicate with the interior space of the hollow pipe, exhaust means for exhausting the interior space, and a protective seal of the seal body in the hollow pipe. Moving means for moving the seal body in a contacted state, and in a state of exhausting from the hollow pipe, the protective seal is pressed against the hollow pipe together with the seal body and moved by the moving means, thereby moving the protective seal. Rotate the hollow pipe while sucking into the opening, wrap the protective seal around the hollow pipe, and peel off the protective seal from the seal body To.
[0008]
Thus, since the hollow pipe winds up the protective seal in a state where the protective seal is sucked into the opening of the hollow pipe, the protective seal that is difficult to peel can be reliably peeled and removed.
[0009]
Further, the protective seal is sucked into the opening by bringing the hollow pipe port into contact with the vicinity of the center of the seal body, and the hollow pipe is rotated in the first direction in this state, and the protective seal is wound around the hollow pipe and sealed. The protective seal is peeled off from the main body, and then the hollow pipe port is brought into contact with the center of the seal main body to suck the remaining protective seal into the opening. In this state, the hollow pipe is rotated in the second direction. It is preferable to wind the protective seal around the hollow pipe and peel the protective seal from the seal body. When the protective seal is divided into two at the central portion of the sealing material, the protective seal can be peeled by winding the protective seal in both directions from the central portion. In many cases, both end portions of the sealing material and the protective seal are processed into various shapes depending on the object to be attached. However, the effective protective seal can be peeled off by peeling from the central portion.
[0010]
In addition, the protective seal has air supply means for supplying air to the internal space of the hollow pipe, and when the peeling of the protective seal from the seal main body is completed, the protective seal is wound around the hollow pipe by blowing air from the exhaust port It is preferable to peel off. As a result, the wound protective seal can be easily eliminated.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
FIG. 1 is a schematic perspective view illustrating a configuration of a protective seal peeling apparatus according to an embodiment. Both ends of the hollow pipe 10 are rotatably supported by bearings 12. A plurality of openings 14 are arranged in a straight line on the surface of the hollow pipe 10 along the axial direction. The opening 14 communicates the internal space of the hollow pipe 10 with the outside.
[0013]
An actuator 16 is connected to one end of the hollow pipe 10, and the hollow pipe 10 can be rotated by this actuator 16. In this example, the actuator 16 is for returning to the original position, and the hollow pipe 10 rotated in one direction is rotated in the opposite direction to return to the original position where the plurality of openings 14 face upward.
[0014]
An air pipe 20 is connected to the other end of the hollow pipe 10 via a joint 18. This joint 18 cuts off the rotation of the hollow pipe 10 so as not to be transmitted to the air pipe 20 side, and connects the hollow pipe 10 and the air pipe 20. An air supply / exhaust device 22 is connected to the other end of the air pipe 20, and the air supply / exhaust device 22 supplies air into the air pipe 20 or exhausts air therefrom. The air supply / exhaust device 22 can perform either air supply / exhaust depending on whether the suction side or the discharge side of a normal air pump is connected.
[0015]
A controller 24 is provided. The controller 24 performs overall control such as supply / exhaust of the air supply / exhaust device 22 and driving of the actuator 16 as well as operation of a robot not shown.
[0016]
Next, the operation of such an apparatus will be described with reference to FIG. First, the robot goes to the seal stocker and sucks the seal material 32 with the hand 30. The hand 30 adsorbs the sealing material 32 to the surface of the hand 30 by evacuation from the internal space. The sealing material 32 is formed by attaching protective seals 32b to both surfaces of the seal body 32a, and the seal body 32a functions as a double-sided adhesive tape. In FIG. 2, the protective seal 32b is shown only on the side to be peeled off.
[0017]
Then, the robot reaches the peeling station where the protective seal peeling device is arranged, with the seal material 32 adsorbed on the hand 30, and as shown in FIG. , Slightly to the right of the center) against the opening 14 of the hollow pipe 10. Here, the protective seal 32b is divided into two at the center. In this case, the protective seal 32b divided in two may be attached to the seal body 32a, but the attached protective seal may be divided by a cutter or the like before the peeling. The protective seal 32b is attached to the seal body 32a with a predetermined adhesive, and the protective seal 32b and the adhesive material may be cut with a cutter. It is also preferable to automate this cutting.
[0018]
The axial length of the hollow pipe 10 is set to be slightly wider than the lateral width of the sealing material 32, and the entire width direction of the seal body 32 a is pressed against the hollow pipe 10. In this state, air is exhausted from the inside of the hollow pipe 10 by the controller 24 by the air supply / exhaust device 22. Exhaust may be started in advance. As a result, the tip portion of the sealing material 32 is adsorbed to the hollow pipe 10.
[0019]
Next, as shown in FIG. 2B, the robot moves the hand 30 so as to pass above the hollow pipe 10. Thereby, the hollow pipe 10 is driven and rotated, but the hand 30 is moved in a certain direction as it is. At this time, the protective seal 32 b of the sealing material 32 is attracted to the opening 14 of the hollow pipe 10, and the opening 14 moves away from the sealing material 32 by the rotation of the hollow pipe 10. Therefore, the protective seal 32b is peeled from the seal body 32a and wound around the hollow pipe 10.
[0020]
Then, as shown in FIG. 2C, the protective seal 32b is wound up with the movement of the hand 30, and when the sealing material 32 is separated from the hollow pipe 10, the protective seal is completely removed from the seal body 32a. It has been peeled off.
[0021]
Next, as shown in FIGS. 2D to 2F, the left side of the protective seal 32b divided into two parts is also peeled off in the same manner. In this case, first, the hollow pipe 10 is pressed slightly to the left of the center of the sealing material 32 in the drawing, the sealing material 32 is moved in the opposite direction, and the protective seal 32b is peeled off.
[0022]
Next, the robot moves to the seal application station while adsorbing the seal material 32 from which the protective seal 32b has been peeled off, and attaches the seal material 32 to the surface of the workpiece.
[0023]
When the protective seal 32 b is wound up and removed, air is supplied from the air supply / exhaust device 22 into the hollow pipe 10, and air is ejected from the opening 14. In the case of FIG. 2, the two-time protective seal 32b after FIGS. 2 (c) and (f) is removed. As a result, as shown in FIG. 3, the protective seal 32 b wound around the hollow pipe 10 is detached from the hollow pipe 10 and falls downward. Under the hollow pipe 10, a recovery protective seal receiver 34 is provided, and the protective seal 32b is recovered here and discarded as appropriate. In FIG. 3, a hobber 36 for guiding the falling protective seal 32 b is provided.
[0024]
The hollow pipe 10 is returned to the origin (position where the opening 14 faces upward) by the actuator 16. This prepares for the next processing for the sealing material 32.
[0025]
Note that all such operations are achieved by the controller 24 controlling each device.
[0026]
As described above, according to the apparatus of the present embodiment, the protective seal 32b can be effectively peeled by moving the robot while the seal material 32 is adsorbed to the hand 30.
[0027]
In particular, since the tip portion of the sealing material 32 is sucked from below the protective seal 32b, only the lower protective seal 32b can be effectively peeled from the seal body 32a. The suction from the opening 14 may be started before the tip portion of the sealing material 32 reaches the top of the opening 14, but when the tip portion of the sealing material 32 reaches just above the opening 14, the hand 30 is stopped. Then, it is preferable that suction from the opening 14 is started, the protective seal 32b is sucked into the opening 14 and separated from the seal body 32a, and then the hand 30 is moved. It is also preferable to place the tip of the sealing material 32 above the opening and then lower it and press it against the hollow pipe 10. Thereby, in the process in which the sealing material 32 approaches the hollow pipe 10, the peeling of the protective seal 32 b can be promoted using the air flow flowing into the opening 14.
[0028]
In the present embodiment, the hollow pipe 10 is driven to rotate and winds the protective seal 32b. Accordingly, the protective seal 32b can be reliably wound up without controlling the rotation of the hollow pipe 10.
[0029]
Furthermore, in this embodiment, the protective seal 32b is divided into two at the center. Then, the protective seals 32b are peeled in half in order. The shape of the sealing material 32 is determined according to the object to be attached. Therefore, the overall shape is, for example, as shown in FIG. 5, and various notches are formed at both ends of the sealing material 32. In such a case, when the protective seal 32b is peeled off from the end portion of the sealing material, a part of the protective seal 32b may be broken and a part of the protective seal 32b may remain. In other words, a large force is applied to the protective seal 32b crank-shaped portion or the like when it is peeled off, which may be broken. In the present embodiment, since the protective seal 32b is peeled toward both ends with the dividing portion at the center as a boundary, the protective seal 32b is surely peeled from the seal body 32a without being broken.
[0030]
FIG. 4 is a diagram showing an overall configuration of a protective seal pasting system using the protective seal peeling device of the present embodiment. Robot 40 is supported by the support frame 42 is movable in the horizontal direction along the support frame (lateral direction in the drawing). Further, the robot 40 has a pair of arms 46 that can rotate around the rotation axis 44, and the hand 30 is provided on the arms.
[0031]
The robot 40 first goes to the seal removal station. At this time, the pair of arms 46 is in an open state. In this state, the hand 30 is lowered with the arm 46 in the vertical direction. A pair of seal stockers 48 are disposed below the pair of hands 30, and the hand 30 sucks the sealing material in a lowered state. And it raises again in the state which hold | maintained the sealing material under the hand 30. FIG.
[0032]
As described above, when the sealing material is held in the hand 30, the robot 40 moves to the horizontal direction and reaches the seal peeling station. In this seal peeling station, the above-described protective seal peeling device is provided below the hand 30, and the protective seal 32b is peeled from the sealing material 32 as described above.
[0033]
Next, the robot 40 moves to the sticking station. The workpiece 50 is held at this seal pasting station. Therefore, the hand 30 is lowered, the arm 46 is rotated around the rotation shaft 44, and the sealing material 32 from which the protective seal 32 b sucked by the hand 30 is peeled off is attached to both surfaces of the workpiece 50. The workpiece is, for example, a heat sink.
[0034]
Thus, when the sheet material 32 is affixed to the workpiece 50, the robot 40 once raises the hand 30 while holding the workpiece 50 with both arms 46, and goes to the workpiece unloading station. A workpiece unloading device 52 is provided at the workpiece unloading station. Therefore, the robot 40 lowers the workpiece 50 having the sealing material 32 adhered on the workpiece carry-out device 52, and releases the workpiece 50 here. Therefore, the work 50 on which the sealing material 32 is affixed is carried out.
[0035]
【The invention's effect】
Thus, according to the present invention, since the hollow pipe winds up the protective seal in a state where the protective seal is sucked into the opening of the hollow pipe, the protective seal that is difficult to peel can be reliably removed.
[0036]
Further, when the peeling of the protective seal from the seal body is completed, the protective seal wound around the hollow pipe can be easily eliminated by ejecting air from the exhaust port.
