[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a further detailed description of the fixture for bending the long and short wires of the terminal of the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0024] See also Figures 1 to 6 The jig for bending the long and short wires of the terminal of the embodiment of the utility model comprises a base 1; a bending mechanism 2 arranged on the base 1, comprising a clamping device 21, a fixing device 22, and a rotating device 23, wherein the clamping device 21 is arranged to slide horizontally along the base 1, the clamping device 21 is used to clamp and fix the terminal, the fixing device 22 is arranged to slide vertically along the base 1, the fixing device 22 is used to place the terminal, and the rotating device 23 is used to bend the terminal; the rotating device 23 comprises a rotating cylinder 231, a rack 232, a gear 233 and a rotating plate 234, the rotating cylinder 231 is connected to the rack 232, and is used to drive the rack 232 to slide back and forth, the gear 233 is meshed with the rack 232, and the gear 233 is coaxially connected with the rotating plate 234; and a preparation area 3 arranged on the base 1, which is used to feed the terminal to be processed into the bending mechanism 2.

[0025] In the above embodiment, first, the terminals to be processed are neatly placed in the material preparation area 3 of the jig base 1. This makes full preparation for the subsequent bending operation. Next, the jig starts to work automatically. The material setting device 22 slides vertically along the base 1, moves to the top of the material preparation area 3, accurately grabs a terminal and fixes it. Then, the material setting device 22 moves upward with the terminal until it reaches the vicinity of the rotating device 23. At this time, the clamping device 21 starts to work. It slides horizontally along the base 1 and moves to the terminal position fixed by the material setting device 22. The clamping device 21 works together to accurately and firmly clamp the terminal. The purpose of this step is to ensure that the terminal can remain stable and motionless during the subsequent bending process to avoid inaccurate bending caused by movement or shaking. When the terminal is firmly clamped, the rotating device 23 starts to start. The rotating cylinder 231 serves as a power source to drive the rack 232 to slide back and forth. The rack 232 is tightly meshed with the gear 233, so the movement of the rack 232 will drive the gear 233 to rotate. The gear 233 is coaxially connected to the rotating plate 234, so the rotation of the gear 233 will be transmitted to the rotating plate 234, causing it to start rotating. The rotation of the rotating plate 234 is the key to the bending operation. Since the wires on the terminal are subjected to the rotational force of the rotating plate 234, they will be bent and bent according to a preset angle and path. The rotation speed and angle of the rotating plate 234 are precisely calculated and controlled to ensure the accuracy and consistency of the bending. During the entire bending process, the various components of the jig work together through a precise transmission mechanism and control system to ensure smooth bending. In summary, the jig for bending the long and short wires of the terminal realizes efficient and accurate bending of the terminal wires through the preparation of the material preparation area 3, the fixation of the material setting device 22, the clamping of the clamping device 21, and the bending operation of the rotating device 23.

[0026] See also Figures 1 to 6 In another embodiment, the clamping device 21 includes a clamping cylinder 211, a push plate 212, a cam plate 213 and a clamping plate 214. The clamping cylinder 211 is connected to the push plate 212. The clamping cylinder 211 is used to push the push plate 212 to move horizontally. The cam plate 213 is connected to the push plate 212. The cam plate 213 is provided with two inclined slide grooves 215. The clamping plate 214 is arranged with the slide grooves 215.

[0027] In the above embodiment, when the clamping cylinder 211 receives the start signal, it pushes the push plate 212 to move horizontally. The push plate 212 is directly connected to the clamping cylinder 211, so the piston movement of the cylinder will be directly converted into the linear movement of the push plate 212. When the push plate 212 moves, the cam plate 213 connected thereto also moves. The cam plate 213 is designed with two inclined slide grooves 215, which have an inclined angle and are used to guide the cam movement of the clamping plate 214.

[0028] As the push plate 212 moves, the clamping plate 214 is placed in the slide groove 215 of the cam plate 213 and is guided by the slide groove 215. Since the slide groove 215 is inclined, the movement path of the clamping plate 214 will also change accordingly. When the push plate 212 moves forward, the clamping plate 214 will gradually move inward, that is, close to the clamped terminal, under the guidance of the slide groove 215. This inward movement of the clamping plate 214 enables it to clamp and fix the terminal.

[0029] See also Figures 1 to 6 In another embodiment, the material fixing device 22 includes a material fixing cylinder 221, a fixed plate 222, a material blocking plate 223, and a positioning column 224. The material fixing cylinder 221 is connected to the positioning column 224, and the material fixing cylinder 221 is used to drive the positioning column 224 to move up and down. The material blocking plate 223 is arranged at one end of the positioning column 224, and the fixed plate 222 is arranged at one end of the positioning column 224.

[0030] In the above embodiment, after receiving the working instruction, the fixed material cylinder 221 starts to start and drives the positioning column 224 to move up and down. One end of the positioning column 224 is connected to the baffle plate 223. As the positioning column 224 moves up and down, the baffle plate 223 will also move. The main function of the baffle plate 223 is to block and position the terminal to be processed to ensure that the terminal can be kept in the correct position during the bending process. At the same time, the other end of the positioning column 224 is connected to the fixed plate 222. The function of the fixed plate 222 is to provide a stable support surface so that the positioning column 224 and the baffle plate 223 can remain stable and accurate during the movement. The design of the fixed plate 222 usually takes into account its rigidity and stability to ensure that it can withstand the effects of the terminal and the bending force during the bending process. When the fixed material cylinder 221 drives the positioning column 224 to rise, the baffle plate 223 also rises, and an appropriate space is formed between it and the fixed plate 222, allowing the terminal to be placed therein. The operator can place the terminal to be processed between the baffle plate 223 and the fixing plate 222, ensuring that one end of the terminal is in close contact with the baffle plate 223 to achieve preliminary positioning. Subsequently, the dosing cylinder 221 drives the positioning column 224 to descend, driving the baffle plate 223 and the fixing plate 222 to clamp the terminal together. In this way, the terminal is firmly fixed in the dosing device 22, ready for the subsequent bending operation.

[0031] See also Figures 1 to 6 In another embodiment, two bending mechanisms 2 are provided.

[0032] In the above embodiment, the terminal usually has two iron wires that need to be bent. After the first bending mechanism 2 bends the wires of the terminal, the second bending mechanism 2 bends the other iron wire, thereby improving the bending efficiency.

[0033] See also Figures 1 to 6 In another embodiment, two material preparation areas 3 are provided.

[0034] In the above embodiment, when the terminals in one preparation area 3 are sent to the bending mechanism 2 for bending, the operator can continue to place new terminals to be processed in another preparation area 3. In this way, when the terminals in the first preparation area 3 are processed, the terminals in the second preparation area 3 are ready and can be immediately sent to the bending mechanism 2 for processing, thereby reducing waiting time and improving production efficiency.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
