An automated forming device for capacitor leads

Abstract

This utility model provides an automatic forming device for capacitor leads, relating to the field of capacitor processing technology. It includes: a base plate, with two upright plates fixedly mounted on the top of the base plate. Cylinders are fixedly mounted on opposite sides of the two upright plates, and the output ends of the cylinders pass through the upright plates and are fixedly mounted with L-shaped plates. In use, the operator activates an electromagnet, causing the iron storage base to rise due to attraction. A spring in the other positioning groove is compressed. Then, the operator activates a motor, whose output drives a rotating shaft and turntable to rotate. Based on the shape of the capacitor's outer wall, the corresponding clamping plate is rotated to the side closest to the capacitor. When it is about to reach the clamping position, the electromagnet is de-energized, and the spring force pushes the storage base downwards. The roller contacts the top of the turntable until it enters the positioning groove, where it contacts a pressure sensor. The motor then stops working to prevent excessive movement of the clamping plate, which could affect clamping. This allows for the clamping of capacitors of different shapes.

Description

Technical Field

[0001] This utility model relates to the field of capacitor processing technology, and in particular to an automatic forming device for capacitor leads. Background Technology

[0002] A capacitor is a core component in electronic circuits used to store electrical charge and energy. It consists of two conducting plates and an insulating dielectric medium in between. Its core functions include energy storage, filtering, and signal coupling, and it is widely used in power management, communications, and industrial control. The capacitor leads are the key part for connecting the capacitor to the circuit; their structure, polarity, soldering methods, and maintenance techniques directly affect circuit performance.

[0003] In the existing technology, during the traditional production of some capacitors, it is usually necessary to bend and shape the capacitor leads according to the required application. The bending die moves towards the leads and contacts the capacitor leads to bend and shape them. In order to prevent the capacitor from moving, a clamping device is usually provided. However, the shape of the clamping plate of the clamping device is usually fixed. Therefore, when clamping capacitors of other shapes, the contact area is small, which may lead to unstable clamping. Utility Model Content

[0004] This utility model mainly provides an automatic forming device that facilitates and improves replacement efficiency and prevents unstable clamping of capacitor leads.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic forming device for capacitor leads, comprising: a base plate, upright plates, a cylinder, an L-shaped plate, a motor, a rotating shaft, a turntable, a connecting rod, a clamping plate, a positioning groove, a pressure sensor, an electromagnet, a spring, a storage seat, rollers, and a limiting rod. Two upright plates are used, and the upright plates are fixedly installed on the top of the base plate. The cylinder is fixedly installed on one side of the two upright plates facing away from each other. The output end of the cylinder passes through the upright plate and is fixedly installed on the L-shaped plate. The motor is fixedly installed on the top of the L-shaped plate, and the output end of the motor passes through the L-shaped plate and is fixedly installed on the top of the L-shaped plate. A rotating shaft is fixedly installed, and a turntable is fixedly installed at the bottom of the rotating shaft. Four evenly distributed connecting rods are fixedly installed on the outer wall of the turntable. A clamping plate is fixedly installed at one end of the connecting rods. Four evenly distributed positioning slots are opened on the top of the turntable. A pressure sensor is fixedly installed on the inner wall of the positioning slot. An electromagnet is fixedly installed on the inner wall of the L-shaped plate. A spring is fixedly installed at the bottom of the electromagnet. A storage seat is fixedly installed at the bottom of the spring. A roller is rotatably installed inside the storage seat. A limiting rod is fixedly installed on the top of the storage seat, and the top of the limiting rod is slidably inserted into the electromagnet.

[0006] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0007] 1. In this utility model, when in use, the operator starts the electromagnet, and the iron storage base is attracted and rises. In another positioning groove, the spring is compressed. Then the operator starts the motor, and the output end of the motor drives the rotating shaft and turntable to rotate. According to the shape of the outer wall of the capacitor, the corresponding clamping plate is rotated to the side closer to the capacitor. When it is about to rotate to the clamping position, the electromagnet is de-energized, and the elastic force of the spring pushes the storage base down. The roller contacts the top of the turntable until it enters the positioning groove. The roller contacts the pressure sensor, and the motor stops working to prevent the clamping plate from moving too much and affecting the clamping. In this way, capacitors of different shapes can be clamped.

[0008] 2. In this utility model, when changing other molds, the operator rotates the handle, the threaded rod rotates and drives the locking block away from the slot, the operator can then pull out the insert plate, replace the new mold, insert the insert plate into the slot, rotate the handle in the opposite direction, and the locking block enters the slot, which improves the replacement efficiency.

Two upright plates 6 are used, and the upright plates 6 are fixedly installed on the top of the base plate 1. The cylinder 7 is fixedly installed on the opposite side of the two upright plates 6, and the output end of the cylinder 7 passes through the upright plate 6 and is fixedly installed on the L-shaped plate 8. The motor 9 is fixedly installed on the top of the L-shaped plate 8, and the output end of the motor 9 passes through the L-shaped plate 8 and is fixedly installed on the top of the L-shaped plate 8. The device is equipped with a rotating shaft 10, a turntable 11 is fixedly installed at the bottom of the rotating shaft 10, four evenly distributed connecting rods 12 are fixedly installed on the outer wall of the turntable 11, a clamping plate 13 is fixedly installed at one end of the connecting rods 12, four evenly distributed positioning grooves 14 are opened on the top of the turntable 11, a pressure sensor 15 is fixedly installed on the inner wall of the positioning groove 14, an electromagnet 16 is fixedly installed on the inner wall of the L-shaped plate 8, a spring 17 is fixedly installed at the bottom of the electromagnet 16, a storage seat 18 is fixedly installed at the bottom of the spring 17, a roller 19 is rotatably installed inside the storage seat 18, and a limiting rod 20 is fixedly installed on the top of the storage seat 18, with the top of the limiting rod 20 slidably inserted into the electromagnet 16.

[0017] like Figure 1 and Figure 4 As shown, two support plates 5 are symmetrically installed on the top of the base plate 1. An electric telescopic rod 21 is fixedly installed on the outer wall of the support plate 5. The telescopic end of the electric telescopic rod 21 passes through the support plate 5 and is fixedly installed with a connecting plate 22. When the operator starts the electric telescopic rod 21, the telescopic end of the electric telescopic rod 21 stretches and pushes the connecting plate 22 to move.

[0018] like Figure 5 As shown, the outer wall of the connecting plate 22 has a slot 24, the inner wall of the slot 24 has a limiting groove 26, the inner wall of the limiting groove 26 has a threaded hole 27, the threaded hole 27 is threadedly connected to a threaded rod 28, the top of the threaded rod 28 is fixedly installed with a handle 29, and the bottom of the threaded rod 28 is movably connected to a locking block 30. When the operator rotates the handle 29, the threaded rod 28 rotates and drives the locking block 30 to move.

[0019] like Figure 5As shown, a plate 31 is slidably installed inside the slot 24. A slot 25 is provided on the top of the plate 31. A mold 23 is fixedly installed on the outer wall of the plate 31. When the card block 30 leaves the slot 25, the operator can pull out the plate 31.

[0020] like Figure 1 As shown, a placement frame 3 is fixedly installed on the top of the base plate 1, and a collection frame 4 is slidably installed inside the placement frame 3. After forming, the capacitor falls into the collection frame 4 for easy collection.

[0021] like Figure 1 As shown, support frames 2 are fixedly installed at the four corners of the bottom of the base plate 1 to support the entire device.

[0022] like Figure 5 As shown, the outer wall of the insert plate 31 fits against the inner wall of the slot 24, and the inner wall of the slot 25 fits against the outer wall of the card block 30. When the card block 30 enters the slot 25, the insert plate 31 can be fixed.

[0023] The device's operation and working principle are as follows: When in use, the operator activates electromagnet 16, causing the iron storage base 18 to rise due to attraction. Meanwhile, spring 17 in the other positioning slot 14 is compressed. Then, the operator activates motor 9, whose output drives the rotating shaft 10 and turntable 11 to rotate. Based on the shape of the capacitor's outer wall, the corresponding clamping plate 13 is rotated to the side closest to the capacitor. Just before reaching the clamping position, electromagnet 16 is de-energized, and the spring force of spring 17 pushes the storage base 18 down, causing roller 19 to contact the top of turntable 11 until it enters the positioning slot 14. Roller 19 then contacts pressure sensor 15, and motor 9 stops working to prevent excessive movement of clamping plate 13, which could affect clamping. This allows for clamping capacitors of different shapes. Finally, the operator activates cylinder 7, bringing the two clamping plates 13 closer together until they clamp the capacitor. Then, the operator activates electric telescopic rod 21, bringing the two molds 23 closer together to contact the capacitor leads, bending and shaping the leads. Finally, the capacitor falls into the collection box 4. When changing to another mold 23, the operator rotates the handle 29, and the threaded rod 28 rotates, causing the locking block 30 to leave the slot 25. The operator can then pull out the insert plate 31, replace the new mold 23, insert the insert plate 31 into the slot 24, and rotate the handle 29 in the opposite direction. The locking block 30 enters the slot 25, which improves the replacement efficiency.
