Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire soldering technology, and in particular to a wire lengthening and shortening mechanism based on a terminal block insertion wire soldering machine. Background Technology
[0002] Currently, the market demand for terminal wires varies. The wire lengths on the same terminal shell can differ, and even when terminal wires are of the same color and in the same order, the required wire length order varies. Therefore, terminal wires produced will vary in length and order depending on the specific product requirements. Current terminal crimping, insertion, and wire bonding equipment can only be customized to fit the actual wire lengths. Such equipment can only crimp, insert, and bond the same type of terminal wire, resulting in extremely poor compatibility. If different wire lengths are required, the equipment either cannot meet the requirements or necessitates replacing a large number of parts, leading to extremely low efficiency and high operational difficulty. Often, it takes a whole day to complete the replacement. Such frequent changes in terminal wire length are a considerable pain for users. Therefore, consumers primarily purchase equipment for producing large quantities of single items or products with varying terminal wire lengths or the same length order. Products requiring frequent replacements are not considered for production on this equipment. Utility Model Content
[0003] The purpose of this invention is to provide a wire lengthening and shortening mechanism based on a terminal crimping and wire bonding machine, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a wire lengthening and shortening mechanism based on a terminal crimping and bonding machine, comprising:
[0005] A base, with a first slide rail assembly on the upper surface of the base, and a second slide rail assembly on the lower end of the base in front of the slide rail assembly;
[0006] The pressing part is located on the upper end face of the base on one side of the second slide rail group. It includes a pressing cylinder. The output end of the pressing cylinder is provided with a first pressing block for pressing the wire. The base on both sides of the pressing cylinder is provided with a wire guide plate.
[0007] The long and short wire splitting section is slidably mounted on the first slide rail group. It includes a slide base, a wire splitting mounting base mounted on the slide base, and a power source mounted on the base for driving the slide base. The wire splitting mounting base is provided with a short wire pressing cylinder and a middle wire pressing cylinder on both sides.

[0008] The cable outlet pull plate is slidably mounted on the second slide rail group. The cable outlet pull plate has multiple discharge holes, and the base is equipped with a push cylinder to push the cable outlet pull plate.
[0009] The clamping cylinder drives the first clamping block to clamp the three wires. When the power source drives the slide to pull the wires backward, the short wire clamping cylinder drives the second clamping block to clamp the shortest wire required, and the three wires produce the first wire with a length difference. When pulling backward a second time, the middle wire clamping cylinder drives the third clamping block to clamp the second shortest wire required. At this time, if the pulling continues, the three wires produce the second wire with a length difference, so as to achieve the wires of their respective lengths and their length order.
[0010] Preferably, the slide is provided with a silicone pad, which is located at the bottom of the branch mounting base.
[0011] Preferably, the wire guide plate and the wire mounting base are provided with wire holes corresponding to the discharge holes.

The sensor is electrically connected to the motor.
[0014] Preferably, a stop block is provided on the base along the forward direction of the slide, and the stop block is integrated with the base.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. When the power source drives the slide to pull the wire backward, the short wire pressing cylinder drives the second pressing block to press the shortest wire required, creating the first wire with a length difference among the three wires. When pulling backward a second time, the middle wire pressing cylinder drives the third pressing block to press the second shortest wire required. Continuing to pull backward creates the second wire with a length difference among the three wires. Then, the clamping cylinder drives the first pressing block to clamp the three wires, achieving the desired length and order of the wires. This invention allows for flexible adjustment of the wire length and order, greatly improving equipment compatibility and production efficiency. In actual operation, simply setting the wire length order according to product requirements allows the mechanism to automatically complete the wire lengthening and cutting without frequent parts replacement, significantly reducing operational difficulty and time costs. Furthermore, the emergence of the wire lengthening and shortening mechanism in the terminal wire bonding machine provides a new solution for the terminal wire manufacturing industry, meeting the market's demand for diversified and customized terminal wires, while also promoting the further development of wire soldering technology.

[0023] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0024] Please see Figure 1 and Figure 2 This embodiment provides a wire lengthening and shortening mechanism based on a terminal crimping and wire bonding machine. The wire lengthening and shortening mechanism based on the terminal crimping and wire bonding machine includes a base 10, a pressing part 20, a long and short wire separating part 30, and a wire pulling plate 40.
[0025] Specifically, a first slide rail assembly 101 is provided on the upper surface of the base 10, and a second slide rail assembly is provided on the lower end of the base 10 in front of the slide rail assembly; a pressing part 20 is provided on the upper surface of the base 10 on one side of the second slide rail assembly, which includes a frame 201, two pressing cylinders 202 are provided on the frame 201, and a first wire pressing block 203 for pressing the wire is provided at the output end of the pressing cylinder 202. A wire separating guide plate 204 is provided on both sides of the pressing cylinder 202; the long and short wire separating part 30 includes a slide seat that slides on the first slide rail assembly 101. The slide 301 includes a wire distribution mounting base 302 on the slide 301 and a power source on the base 10 for driving the slide 301. The wire distribution mounting base 302 has a short wire pressing cylinder 303 and a middle wire pressing cylinder 304 on both sides. The output ends of the short wire pressing cylinder 303 and the middle wire pressing cylinder 304 are respectively provided with a second pressing block and a third pressing block. The wire output pull plate 40 is slidably mounted on the second slide rail group. The wire output pull plate 40 is provided with multiple discharge holes 401. The base 10 is provided with a push cylinder 402 for pushing the wire output pull plate 40.
[0026] When the above-mentioned wire lengthening and shortening mechanism based on the terminal block bonding machine is working, after setting the pullback length value of each wire, when the power source drives the slide 301 to pull the wire backward, the short wire pressing cylinder 303 drives the second pressing block to hold the shortest wire required, and the three wires produce the first wire with a length difference; when pulling backward a second time, the middle wire pressing cylinder 304 drives the third pressing block to press the second shortest wire required, and at this time, the wire continues to be pulled backward, and the three wires produce the second wire with a length difference. The pressing cylinder 202 drives the first pressing block 203 to press the three wires. Finally, the cutter uniformly cuts and strips these wires, and then the push cylinder 402 pushes the wire pull plate 40 to pull out the cut wires, so as to achieve the wires of their respective lengths and their length order.
[0027] In an optional embodiment, to prevent the wire from deforming when squeezed by the second and third pressure blocks, a silicone pad 3011 is provided on the slide 301. The silicone pad 3011 is located at the bottom of the wire mounting base 302. The silicone pad 3011 is designed with good elasticity and cushioning performance, which can effectively absorb the impact force when the pressure cylinder is applied, protecting the wire from damage. When the second and third pressure blocks press the wire, the silicone pad 3011 can provide uniform support, ensuring that the wire remains straight during the pressing process and avoiding deformation due to uneven force. This design not only improves the processing accuracy of the wire but also ensures the quality and reliability of the final product.
[0028] In an optional embodiment, to prevent the wires from tangling or twisting together during pulling, the wire guide plate 204 and the wire mounting base 302 are provided with guide holes 50 corresponding to the discharge holes 401. The design of the guide holes 50 ensures that each wire can pass smoothly during pulling and maintain a relatively independent position, effectively avoiding the problem of tangling or twisting between wires. This attention to detail not only improves the smoothness of wire pulling but also ensures the accuracy and stability of the wires in subsequent processing steps. In addition, the size and shape of the guide holes 50 are precisely calculated to match the specifications of the wires, further reducing friction and resistance during pulling and improving overall work efficiency. Through these careful designs, the wire lengthening and shortening mechanism exhibits greater flexibility and reliability when handling complex and varied terminal wire length differences and length sequence settings.
[0029] In an optional embodiment, the cable outlet pull plate 40 includes a guide plate 403 and an outlet plate 404. The guide plate 403 is slidably connected to the second slide rail assembly. The discharge hole 401 is located on the outlet plate 404. A connecting plate 405 connected to the output end of the push cylinder 402 is provided on the side of the guide plate 403. A buffer 406 abuts against the base 10 on the connecting plate 405. This design makes the cable outlet pull plate 40 more stable and reliable during operation. The connection between the connecting plate 405 and the output end of the push cylinder 402 realizes the automated operation of the cable outlet pull plate 40. Through the push of the cylinder, the moving distance and speed of the cable outlet pull plate 40 can be precisely controlled, thereby achieving precise setting of the terminal wire length difference and length sequence. The buffer 406 plays a protective role. When the cable outlet pull plate 40 moves to the extreme position, the buffer 406 can absorb the impact force, prevent damage caused by collision, and extend the service life of the equipment.
[0030] In an optional embodiment, the power source includes a motor 305, a lead screw 306 connected to the output shaft of the motor 305, and an L-shaped connecting block 307 disposed on the slide 301. The L-shaped connecting block 307 has a flange threadedly connected to the lead screw 306. The side wall of the L-shaped connecting block 307 is provided with a sensing plate 308, and the base 10 is provided with a sensor 309 that senses the sensing plate 308. The sensor 309 is electrically connected to the motor 305. In addition, a stop block 310 is provided on the base 10 along the forward direction of the slide 301, and the stop block 310 is integral with the base 10. This power source design ensures that the wire lengthening and shortening mechanism can work accurately and stably. The motor 305, as the power core, drives the lead screw 306 to rotate through the output shaft, and the flange on the L-shaped connecting block 307 is threadedly connected to the lead screw 306, so that the slide 301 can move accurately along the axial direction of the lead screw 306. The cooperation between the sensing plate 308 and the sensor 309 serves as a position detection mechanism. When the slide 301 moves to the predetermined position, the sensing plate 308 triggers the sensor 309, which then sends a signal to the motor 305, controlling the motor 305 to stop working. This achieves precise control of the slide 301's position. Furthermore, the stop block 310 acts as a limit, preventing the slide 301 from exceeding the predetermined range during movement, further improving the safety and stability of the equipment. This series of designs works together to enable the wire lengthening and shortening mechanism to achieve precise and free setting of the terminal wire length difference and sequence.
[0031] In summary, when the power source drives the slide block 301 to pull the wire backward, the short wire pressing cylinder 303 drives the second pressing block to hold the shortest wire required, creating the first length difference among the three wires. When pulling backward a second time, the middle wire pressing cylinder 304 drives the third pressing block to hold the second shortest wire required. Continuing to pull backward creates the second length difference among the three wires. Then, the clamping cylinder 202 drives the first pressing block 203 to clamp the three wires, achieving the desired length and order of the wires. This invention allows for flexible adjustment of the wire length and order, greatly improving equipment compatibility and production efficiency. In actual operation, simply setting the wire length order according to product requirements allows the mechanism to automatically complete the wire lengthening and cutting without frequent component replacement, significantly reducing operational difficulty and time costs. Furthermore, the emergence of the wire lengthening and shortening mechanism based on the terminal wire bonding machine has brought new solutions to the terminal wire manufacturing industry, meeting the market's demand for diversified and customized terminal wires, and also promoting the further development of wire soldering technology.
[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
