Description

Technical Field

[0001] This application relates to the field of electrical components technology, and more specifically, to an automatic terminal crimping mechanism. Background Technology

[0002] A terminal is an electrical component used in a circuit to make electrical connections or disconnections. It is typically made of conductive metallic materials and insulating materials, and is used to transmit current and signals between wires, cables, or devices.

[0003] Terminals are connected to the ends of wires. Typically, terminals are made by folding and pressing a metal sheet against the exposed end of the wire; this operation is also called terminal crimping. In existing technology, terminal crimping usually involves using a cylinder to extend and retract, causing a forming plate to press the metal sheet. However, this structure requires sufficient space to install the cylinder, making the entire structure relatively large. Since the wire needs to move between multiple stations, the larger structure increases the wire's travel distance and reduces efficiency. Furthermore, when using a cylinder for terminal crimping, the inherent limitations of the cylinder result in low crimping efficiency, inconsistent quality, and a tendency to malfunction. All of these significantly reduce production efficiency and hinder factory development.

[0004] Therefore, it is necessary for the inventors to design a new automatic terminal crimping mechanism to overcome the above problems. Summary of the Invention

[0005] The main objective of this application is to provide an automatic terminal crimping mechanism to solve the problems of low terminal crimping efficiency, unstable quality, and unstable mechanism in related technologies.

[0006] To achieve the above objectives, this application provides an automatic terminal crimping mechanism, including a mounting base plate and a terminal transfer mechanism. The terminal transfer mechanism has a rotating shaft, which is rotatably connected to the mounting base plate. A sliding frame is also fixedly installed on the top of the mounting base plate, and a forming plate is slidably installed on the sliding frame. A linkage structure is fixedly installed between the rotating shaft and the forming plate, and the linkage structure is used to drive the forming plate to slide up and down.

[0007] Optionally, the linkage structure includes a rotating plate, a connecting rod, and a slider. The slider is slidably connected to the mounting base plate, the rotating plate is fixedly connected to the rotating shaft, one end of the connecting rod is rotatably connected to the forming plate, and the other end of the connecting rod is rotatably connected to one end of the slider. A conversion structure is fixedly provided between the other end of the slider and the rotating plate. The conversion structure is used to convert the rotation of the rotating plate into the sliding of the slider.

[0008] Optionally, the conversion structure includes a rotating groove and a sliding pin. The rotating groove is formed at the bottom of the rotating plate, and a cam is fixedly disposed in the rotating groove. One end of the sliding pin is inserted between the cam and the inner wall of the rotating groove, and the other end of the sliding pin is fixedly connected to the slider.

[0009] Optionally, two limiting blocks are fixedly provided on the mounting base plate, and a sliding groove is provided on the opposite side of the two limiting blocks, and the two sides of the slider are slidably disposed in the sliding groove.

[0010] Optionally, the bottom of the sliding frame has an opening for accommodating the movement of the connecting rod.

[0011] Optionally, the rotating plate, the rotating groove, and the cam are integrally formed.

[0012] Optionally, the rotating plate is fixedly connected to the rotating shaft via a positioning key.

[0013] Optionally, a gear is also fixedly mounted on the rotating shaft, and a motor is fixedly mounted on the top end of the mounting base plate away from the molding plate. The output shaft of the motor is connected to the gear via a transmission belt.

[0027] like Figures 1 to 3 As shown, an automatic terminal crimping mechanism includes a mounting base plate 1 and a terminal transfer mechanism 2. The terminal transfer mechanism 2 has a rotating shaft 3, which is rotatably connected to the mounting base plate 1. A sliding frame 4 is also fixedly installed on the top of the mounting base plate 1. A forming plate 5 is slidably installed on the sliding frame 4. A linkage structure is fixedly installed between the rotating shaft 3 and the forming plate 5. The linkage structure is used to drive the forming plate 5 to slide up and down.

[0028] Specifically, the terminal transfer mechanism 2 is a structure used to transfer the metal sheet 17 forming the terminal. Existing terminal transfer mechanisms 2 typically also have a structure that pushes the metal sheet 17 into a position to engage with the forming plate 5. Usually, the pressing motion of the metal sheet 17 is achieved by rotating the shaft 3 to drive the internal structure of the terminal transfer mechanism 2. Here, the length of the shaft 3 in the prior art is extended. The rotation of the shaft 3, through a linkage structure, drives the movement of the forming plate 5, achieving the same pressing motion of the forming plate 5 on the metal sheet 17. Furthermore, no additional cylinder drive is needed, significantly reducing the size of the equipment. The transmission structure here is a crank-connecting rod mechanism 7, which is stable in operation, produces high-quality terminals, and improves product quality. Simultaneously, the rotation speed of the shaft 3 is easily adjustable, and the rotation method makes terminal crimping more efficient.

[0029] The linkage structure includes a rotating plate 6, a connecting rod 7, and a slider 8. The slider 8 is slidably connected to the mounting base plate 1. The rotating plate 6 is fixedly connected to the rotating shaft 3. One end of the connecting rod 7 is rotatably connected to the forming plate 5, and the other end of the connecting rod 7 is rotatably connected to one end of the slider 8. A conversion structure is fixedly provided between the other end of the slider 8 and the rotating plate 6. The conversion structure is used to convert the rotation of the rotating plate 6 into the sliding of the slider 8. The conversion structure includes a rotating groove 9 and a sliding pin 10. The rotating groove 9 is formed at the bottom of the rotating plate 6. A cam 13 is fixedly provided in the rotating groove 9. One end of the sliding pin 10 is inserted between the cam 13 and the inner wall of the rotating groove 9, and the other end of the sliding pin 10 is fixedly connected to the slider 8.

[0030] Specifically, the rotating shaft 3 drives the rotating plate 6 to rotate. When the rotating plate 6 rotates, the cam 13 inside it rotates synchronously. The distance between the outer edge of the cam 13 and the axial direction of the rotating shaft 3 is variable. Therefore, during the rotation of the cam 13, the sliding pin 10 is repeatedly pressed. The sliding pin 10 drives the slider 8 to slide on the mounting base plate, and then drives the forming plate to slide up and down repeatedly through the connecting rod 7, so as to realize the reciprocating motion of the terminal crimping.

[0031] Two limiting blocks 11 are fixedly installed on the mounting base plate 1. A sliding groove is formed on the opposite side of the two limiting blocks 11, and the two sides of the slider 8 are slidably disposed in the sliding groove. Specifically, the limiting blocks 11 limit the movement of the slider 8 to sliding when the sliding pin 10 is squeezed, and prevents it from deflecting.

[0032] The bottom of the sliding frame 4 has an opening 12 for accommodating the movement of the connecting rod 7. Specifically, when the slider 8 moves, it drives the connecting rod 7 to move, and the opening 12 provides space for the movement of the connecting rod 7.

[0033] The rotating plate 6, the rotating groove 9, and the cam 13 are integrally formed. Specifically, the integral forming method results in higher strength and a longer service life.

[0034] The rotating plate 6 is fixedly connected to the rotating shaft 3 via a positioning key.

[0035] A gear 14 is also fixedly mounted on the rotating shaft 3. A motor 15 is fixedly mounted on the top end of the mounting base plate away from the forming plate 5. The output shaft of the motor 15 is connected to the gear 14 via a transmission belt 16. Specifically, the rotating shaft 3 is driven to rotate by the motor 15. The movement of the rotating shaft 3 drives the metal sheet 17 to the work station and causes the forming plate 5 to press the metal sheet 17. Usually, the terminal crimping mechanism is only a small mechanism in the terminal processing device. The mounting base plate 1 usually needs to slide in the terminal processing device to achieve other processing requirements. Therefore, it is inconvenient to install the motor 15 at the bottom of the mounting base plate 1. Therefore, the gear 14 and the transmission belt are set so that the motor 15 can be set in a position that does not interfere with the sliding of the mounting base plate 1.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
