Description

Technical Field

[0001] This utility model relates to the technical field of bending devices, and in particular to a lead bending device for the production of aluminum electrolytic capacitors. Background Technology

[0002] Aluminum electrolytic capacitors are capacitors that use aluminum foil as electrodes. After production, due to space constraints, specific installation angles may be required during use, necessitating lead bending to adapt them for mounting on corresponding circuit boards. A lead bending device effectively improves the efficiency of lead bending. This lead bending device for aluminum electrolytic capacitor production features a semi-circular structure that converts rotational motion into linear motion. If it were a circular structure, the short rod, being in a fixed position, could only rotate along the inner wall of the circular structure, failing to convert rotational motion into linear motion. With the semi-circular structure, the short rod rotates close to the right angle of the semicircle, transmitting power to the connecting rod and achieving linear motion. The conveying section, with its movable plate and grooved transfer block, stably clamps materials, achieving equidistant conveying. Therefore, a lead bending device for aluminum electrolytic capacitor production is needed.

[0003] Existing lead bending devices for aluminum electrolytic capacitor production are complex in structure, making replacement and repair difficult when problems occur, increasing maintenance costs. Furthermore, they cannot clamp and convey the material, which may rotate due to friction during conveying, causing deviations in the lead bending angle and damaging the leads. Utility Model Content

[0004] The purpose of this utility model is to provide a lead bending device for the production of aluminum electrolytic capacitors, so as to solve the problems mentioned in the background art. The existing lead bending devices for the production of aluminum electrolytic capacitors have a complex structure, are difficult to replace and repair when problems occur, and have high maintenance costs. At the same time, they cannot clamp and transport, and the material may rotate on its own due to friction during the transport process, which may cause the lead bending angle to deviate and damage the lead.

A conveying groove is welded to the upper end of the second support plate. A movable plate is movably installed on one side of the inside of the conveying groove. A conveyor wheel is fixedly installed on the other side of the inside of the conveying groove. A conveyor belt is fitted on the conveyor wheel. An electric cylinder is fixedly installed at one end of the conveying groove. A push block is fixedly installed at the output end of the electric cylinder.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5This utility model provides a technical solution: a lead bending device for aluminum electrolytic capacitor production, including a base 1, a first support plate 2 welded to one side of the base 1, a motor 3 fixedly mounted on one side of the first support plate 2, a drive rod 4 fixedly connected to the output end of the motor 3, a first synchronous pulley 5 fixedly mounted on one end of the drive rod 4, a synchronous belt 6 sleeved on the first synchronous pulley 5, the other end of the synchronous belt 6 sleeved on a second synchronous pulley 7, the second synchronous pulley 7 fixedly mounted on one end of a driven rod 8, a driven rod 8 bearing connected to the center opening of the first support plate 2, and two sets of fixing blocks 9 welded to the side surface of the first support plate 2. A connecting rod 10 is connected to the center of the base 1 and a bearing is connected to it. A bending block 11 is fixedly installed at the end of the connecting rod 10 away from the motor 3. A second support plate 12 is welded to the other side of the base 1. A conveying groove 13 is welded to the upper end of the second support plate 12. A movable plate 14 is movably installed on one side of the inside of the conveying groove 13. A conveying wheel 15 is fixedly installed on the other side of the inside of the conveying groove 13. A conveyor belt 16 is fitted on the conveying wheel 15. An electric cylinder 17 is fixedly installed at one end of the conveying groove 13. A push block 18 is fixedly installed at the output end of the electric cylinder 17. A stabilizing plate 19 is welded to one side of the conveying groove 13. A discharge port 20 is provided at the other end of the conveying groove 13.

[0016] Furthermore, the bearings fixedly installed at the center of the connecting rod 10 and the two sets of fixing blocks 9 are linear bearings. By setting the connecting rod 10 and the fixing blocks 9, the friction of the connecting rod 10 during linear reciprocating motion is reduced, the wear of the connecting rod 10 is reduced, and the connecting rod 10 does not need to be replaced frequently due to wear, which greatly saves costs.

[0017] Furthermore, a photoelectric sensor 21 is fixedly installed on the side surface of the fixing block 9 near one end of the conveying trough 13. The photoelectric sensor 21 is located behind the bending block 11. By setting the photoelectric sensor 21 and the bending block 11, the distance parameters are set. When the bending block 11 approaches, the photoelectric sensor 21 that senses the bending block 11 sends a command to the electric cylinder 17, and the electric cylinder 17 then conveys the material. In this way, the problem of substandard bending effect caused by position deviation can be avoided.

[0018] Furthermore, transfer blocks 22 are fixedly installed at equal intervals on the outer surface of the conveyor belt 16. The conveyor belt 16 is designed with a rack inside and meshes with the conveyor wheel 15. The parts of the transfer blocks 22, the movable plate 14, and the push block 18 that come into contact with the material are all rounded. Through the arrangement of the conveyor belt 16, the conveyor wheel 15, the transfer blocks 22, the movable plate 14, and the push block 18, the conveyor wheel 15 meshes with the rack inside the conveyor belt 16, which greatly reduces friction during conveying, improves conveying efficiency, and the material can be better clamped and conveyed more stably within the rounded structure.

[0019] Furthermore, a spring is fitted around the outer ring of the cylinder between the movable plate 14 and the stabilizing plate 19. The cylinder passes through the stabilizing plate 19. Through the arrangement of the transfer block 22, the movable plate 14, and the stabilizing plate 19, the movable plate 14 and the transfer block 22 fit better without leaving gaps. After the material is pushed, the cylinder passing through the stabilizing plate 19 provides support for the movable plate 14. The spring between the movable plate 14 and the stabilizing plate 19 can help with the reset.

[0020] Furthermore, a circular plate is fixedly installed at the end of the driven rod 8 away from the second synchronous wheel 7. A short rod 23 is welded to the side surface of the circular plate. The connecting rod 10 is designed as a semi-circular structure 24 in the center. The short rod 23 is nested inside the semi-circular structure 24, and a limiting structure is set inside the semi-circular structure 24. With the arrangement of the driven rod 8, the short rod 23, the connecting rod 10 and the semi-circular structure 24, when the driven rod 8 rotates, the short rod 23 rotates with it and fits against the limiting structure inside the semi-circular structure 24, and transmits the power to the connecting rod 10 for linear reciprocating motion.

[0021] Furthermore, a groove structure is provided in the center of the side of the push block 18, and the transfer block 22 corresponds to the groove of the push block 18. With the setting of the push block 18 and the transfer block 22, when the push block 18 completes the conveying and resetting, the transfer block 22 rotates on the conveyor belt 16, passes through the groove to reach the material, and will not be stuck by the push block 18.

[0022] Working principle: First, when in use, place the material with the pins facing upwards. Then, start the motor 3 to drive the active rod 4 to rotate. The active rod 4 drives the first synchronous wheel 5 to rotate. The first synchronous wheel 5 drives the second synchronous wheel 7 to rotate through the synchronous belt 6. The second synchronous wheel 7 drives the driven rod 8. The short rod 23 rotates within the semi-circular structure 24, conforming to the limiting structure, and transmits the power to the connecting rod 10. Then, the connecting rod 10 drives the bending block 11 to bend. After bending, when the bending block 11 is detected by the photoelectric sensor 21, the photoelectric sensor 21 sends a command to the electric cylinder 17 (model KDJ40). Next, the electric cylinder 17 drives the push block 18 to push the material and open the movable plate 14 into the groove between the transfer block 22. Then, the push block 18 resets, and the spring returns the movable plate 14. This cycle repeats until the material is discharged through the discharge port 20, completing the clamping, stable conveying, and bending process.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
