Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a method and apparatus for edge cutting and alignment of electrolytic capacitor lead wires, and in particular, to an automatic assembly machine for electrolytic capacitors, in which electrolytic capacitor lead wires that are closely conveyed by a parts feeder are aligned. A method for edge cutting and alignment of electrolytic capacitor lead wires, in which the electrolytic capacitor lead wires are surely separated one by one by a device with mechanical operation, and the tabs of the electrolytic capacitor lead wires are aligned in the correct direction before being transported to the next process. Regarding equipment.

Conventional technology Conventionally, electrolytic capacitor lead wires, which are conveyed in close contact with each other by a parts feeder, are separated individually via a shutter device, and then dropped into a chute using gravity to send the electrolytic capacitor lead wires to the next process. The transportation method was generally adopted.

However, the shape of the electrolytic capacitor lead wire, which is the object to be conveyed, has various specifications, and since it is extremely lightweight, the speed at which it falls inside the shoe 1 depends on the specifications of the electrolytic capacitor lead wire and the friction coefficient inside the chute. Therefore, each time the specifications of the electrolytic capacitor lead wire change, the takt time between each process needs to be fine-tuned, and if the adjustment is inadequate, it may lead to defective products due to poor connections between processes. Or, in the worst case, the electrolytic capacitor lead wire gets caught in the chute, causing trouble in transportation and lowering the operating rate of the automatic assembly machine.

In addition, since electrolytic capacitor lead wires are transported by a dropping method using shoe 1-, the working speed is determined by the time it takes for the transported object to fall within the chute, so the working speed can be further increased to improve productivity. There was a drawback that it was difficult to manufacture a high-quality automatic assembly machine.

Purpose The present invention has been made in order to eliminate the drawbacks of the above-mentioned prior art, and its purpose is to use electrolytic capacitor lead wires that are closely conveyed by a parts feeder in an automatic assembly machine for electrolytic capacitor lead wires. Accompanied by mechanical operations such as a pre-alignment member and a posture changing conveyance device that securely edge the capacitor lead wires one by one using a shutter device and align the flat portions of the tabs of the electrolytic capacitor lead wires in substantially the same direction. By accurately transporting the electrolytic capacitor lead wire to the next process through the device, work can always be done at a constant speed even if the specifications of the electrolytic capacitor lead wire to be transported change, and electrolytic capacitor lead wires can be stably supplied to each process. The object of the present invention is to improve the operation rate of automatic assembly machines and improve the yield of products.

Another purpose is to accurately set the tough 1-time required for each process by transporting the electrolytic capacitor lead wire, which is an object to be transported, to the next process via a device with mechanical operation. Another object of the present invention is to provide a method and apparatus for edge cutting and alignment of electrolytic capacitor lead wires, which has high productivity and is capable of speeding up the amplifier by about 22% compared to the conventional example.

Function The present invention is constructed as described above, and its function will be explained below. As shown in FIG. 3, the electrolytic capacitor lead wires 10, which are closely attached to each other by inserting the lead wires 11 into the straight feeder a20 of the straight feeder 21 of the parts feeder 2, are attached to the flat portion 1 of the tab 12.
2a is conveyed facing an arbitrary direction, and its progress is temporarily blocked by the holding member 31 of the shutter device 3. Here, when the connecting rod 33 operates in the direction of arrow B, the holding member 31 also moves in the direction of arrow B, and the first one of the electrolytic capacitor lead wires 10 that was stopped by the holding member 31
The book advances beyond the holding member 31 and comes into contact with the holding member 32, where its progress is stopped. When the connecting rod 33 starts moving in the direction of the arrow to return to its original position, the electrolytic capacitor lead wire 10 whose advancement was blocked by the holding member 32 and each tab of the electrolytic capacitor lead wire 10 adjacent to the dirt are removed. By sliding the tip of the holding member 31, which is formed at an acute angle into the shape of a cutting edge, into the contact surface of the holding member 31,
The edge-cutting process for taking out one of the plurality of electrolytic capacitor lead wires 10 that has been conveyed in close contact with each other is completed, and the holding member 32 that had been blocking the progress of the edge-cut electrolytic capacitor lead wire 10 is moved as shown by the arrow. Since it is escaping in the A direction, it starts moving toward the preliminary alignment member 4 by the action of the straight feeder 21. As shown in FIG. 4, the electrolytic capacitor lead wire 10 in contact with the preliminary alignment member is attracted by the magnetic force of the permanent magnet 42 attached to the preliminary alignment plate 41, and the lead wire 11 is attracted to the flat portion 12a of the tab 12. are brought into close contact with the preliminary alignment plate 40 and aligned in a substantially constant direction.

In FIG. 5, the release rod 54 is inserted into the first chuck member 5.
The chuck device 5 was operated so as to come into contact with the electrolytic capacitor lead wires 10 to open the first chuck member 52 and the second chuck member 52, and was waiting to cover the pre-aligned electrolytic capacitor lead wires 10. By pulling back the release rod 54 in the direction of arrow C, the claw 5 is opened by the restoring force of the spring 58.
6 grips the round portion 12b of the tab 12, and the claws 57 grip the lead wire 11 to enter the transport position for the next process. At this time, in the shutter device 3, as the connecting rod 33 operates in the direction of arrow B, the preliminary alignment plates 40, 41 are removed from the electrolytic capacitor lead wire 10 as shown in FIG. As shown in the figure, the sun gear 60 is attached to the arm member 65 by operating the rod 67 in the direction of the arrow. Idle gear 61. As shown by the imaginary line in the same figure, the attitude changing conveyance device 6 consisting of a planetary gear 62 moves the electrolyzer toward the clamping device 7 arranged in the direction of the arrow E while drawing a cycloid curve with translational movement and circular movement. The capacitor lead wire 10 is fed out and assumes a horizontal position.

Further, FIG. 11 shows the locus along which the electrolytic capacitor lead wire 10 is sent out at this time by subdividing the swing angle of the arm member 65, and in the illustrated embodiment, the sun gear 6
Since the ratio of the number of teeth between 0 and the planetary gear 62 is set to 5=2, by swinging the arm member 65 approximately 60 degrees counterclockwise in FIGS. 7 and 11, the rotation by the idle gear 61 is The planetary gear 62 whose direction has been changed rotates approximately 90 degrees clockwise in the figure while revolving in the same direction as the arm member 65, and as a result, the attitude of the electrolytic capacitor lead wire 10, which is the object to be conveyed, is approximately changed. 90° conversion is possible, and the center of gravity of the electrolytic capacitor lead wire 10 moves in an approximate cycloid curve, minimizing the moment of inertia of the electrolytic capacitor lead wire and the inertial force caused by tffi. Impacts during delivery to the clamp device 7 can be alleviated.

Further, as shown in FIG.
It is elastically supported on the base 66 via the holder 66, and is able to escape and rotate in the clockwise direction in FIG. 7 against the tension spring 68. The electrolytic capacitor lead wire 10 is prevented from moving or falling at the moment it is relaxed and gripped by the chuck device 5 installed inside the attitude changing and conveying device.

Next, the first clamp member 71 and the second clamp member 72 of the clamp device 7, which are attached to the index table 8 which is intermittently rotated by a predetermined angle, are changed to the horizontal direction while remaining in the open state. Electrolytic capacitor lead that has been removed! It stops at the first position of the index table 8 shown in FIG. 9, covering the ai o. As the opening member 74 operates in the direction of arrow H, the first clamp member 71 and the second clamp member 72 in the open state grip the lead cotton 11 of the electrolytic capacitor lead wire 10, and then as shown in FIG. Since the release rod 54 operates in the direction of arrow F and the chuck device 5 releases the electrolytic capacitor lead wire 10, the electrolytic capacitor lead wire 10 is thereby transferred from the chuck device 5 to the clamp device 7.

Further, as shown in FIG. 7, the chuck device 5, which remains open due to the rod 67 operating in the direction of the arrow G, returns to the position of the pre-alignment member 4 and connects the next electrolytic capacitor lead wire 10. Get into a gripping position.

As shown in FIG. 9, the clamping device 7, which is located at the first position of the index table 8 that receives and grips the electrolytic capacitor lead wire 10, moves to the second position with the next rotational movement of the index table 8. Start one movement. At this time, the opening member 74 operates in the direction of the arrow 1, but the profile of the cam portion 74b of the opening member is so formed that it does not act on the second position of the index table 8. The opposite clamp device 7 continues to hold the electrolytic capacitor lead wire 10.

The correction device 9 disposed opposite the second position of the index table 8 is operated by pulling the operating rod 97a in the direction of the arrow 4J, as shown in FIG. The member 99 is pulled to the right in FIG. 10, and the holding plate 92a fixed to the tip of the pressurizing part 92 remains open until the electrolytic capacitor lead wire 10 gripped by the clamp device 7 arrives. are doing.

As shown in FIG. 9, at the same time as the clamping device 7 that grips the electrolytic capacitor lead wire 10 arrives at the second position of the index table 8, the actuating rod 97a is moved in the direction of the arrow, as shown in FIG. Because it works,
The pressure member 99 is pushed to the left in FIG.

As a result, the pair of pressurizing rods 90 move in the same direction and press the pair of pressurizing parts 92, so that the upper side of the pressurizing parts rotates counterclockwise and the lower side rotates clockwise. The lead wire guide plate 118 is lowered, and the lead wire 11 is guided by the slave portion 118b and enters the groove 118a.
The lead wire is positioned in the left and right direction. The positioning rod 94, which is fixed to the positioning member 96 via the positioning spring 95 that locks the pressure member and the positioning member 96, is moved until the positioning screw 96a abuts the support base 98 as shown in FIG. Pushed to the left. Due to the operation of the positioning rod 94 at this time, the tip of the positioning rod comes into contact with the flat part 12a of the tab 12, and the electrolytic capacitor lead wire 1 held by the clamp device 7
The 0 position is corrected by pressing the positioning rod 94. Even after the position of the electrolytic capacitor lead wire 10 is corrected, the pressure member 99 is further pushed to the left in FIG. 10, and the pressure member 92 is in contact with the pressure rod 90 fixed to the pressure member. A pair of retaining plates 92 fixed to the tips of the
a is the flat part 12a of the tab 12, as shown in FIG.
The tabs 12 in the pre-aligned state are finally aligned in a certain direction (horizontal direction) by applying pressure, and the orientation is corrected so as not to interfere with the next process.

At this time, when the defective product detection sensor 120 descends from above and its tip 120a contacts the flat part 12a at the correct position in the vertical direction, the electrolytic capacitor lead wire 10 is determined to be a good product, and the next third The electromagnetic solenoid 112 of the defective product sorting device 111 is not activated because the electric signal that should pass through the position is output from the control device, but the tip 120a of the defective product detection sensor 120 is lowered.
If the capacitor does not contact anywhere or contacts at a too high position, it is determined to be a defective product, and an electrical signal is sent from the control device to open the clamp device 7 at the next third position and cause the electrolytic capacitor lead wire 10 to fall off. When the defective product is removed, the electromagnetic solenoid 112 shown in FIG. 1 is activated, and the lever 115 presses the roller 78 to open the clamp device 7 and remove the defective product. Thereafter, this process is repeated to sort out non-defective products and defective products.

As described above, according to the apparatus of the present invention, the electrolytic capacitor lead wires 10 are mechanically conveyed one by one from the straight feeder 21, and the flat portions 12a of the tabs 12 are aligned in a perfectly horizontal state, and the It is conveyed onto the foil 15. According to the device of the present invention, the electrolytic capacitor lead wires 10 are aligned at a rate of one wire per 0.55 seconds, and the aluminum foil 1
5. In the conventional example, this time was 0.7 seconds, so this is a speedup of about 22% compared to the conventional example.

Effects Since the present invention is configured and operates as described above, in an automatic assembly machine for electrolytic capacitors, etc., the shutter device can securely transport the electrolytic capacitor lead wires one by one, which are closely conveyed by the parts feeder. Trim the edges and align the flat part of the tab of the electrolytic capacitor lead wire with approximately the same
Because the specifications of the electrolytic capacitor lead wires of the objects to be transported are changed, the materials are accurately transported to the next process via devices that involve mechanical operations such as a pre-alignment member that aligns them in the direction of The effect is that the work is always carried out at a constant speed, and electrolytic capacitor lead wires can be stably supplied to each process. Moreover, as a result, there is an effect that the operating rate of the automatic assembly machine can be improved and the performance of the product can be improved.

In addition, since the electrolytic capacitor lead wire, which is the object to be transported, is transported to the next process via a device that involves mechanical operation, the takt time required for each process can be set accurately, resulting in high productivity. This is an extremely effective invention that can provide a highly efficient method and device for cutting and aligning electrolytic capacitor lead wires that can achieve a speed amplifier of about 22% compared to the conventional example.
