Description

Technical Field

[0001] This application relates to the field of terminal processing technology, and in particular to terminal hot melt crimping equipment. Background Technology

[0002] In the terminal and cable connection process in the fields of electronics, electrical engineering, and automotive wiring harnesses, the reliable connection between terminals and cables relies on two core processes: "crimping" and "thermal melting." The crimping process uses mechanical force to form a preliminary fixed connection between the terminal and the cable, ensuring that their positions are relatively stable. The thermal melting process fills the connection gap between the terminal and the cable with high-temperature molten solder, enhancing the conductivity of the contact surface and the structural rigidity.

[0003] Currently, most terminal processing equipment in the industry designs these two processes as independent separate processes, that is, crimping and heat fusion are completed on different equipment and at different workstations. This process separation design has technical pain points in actual use, affecting processing efficiency and quality. In order to solve the above problems, terminal heat fusion crimping equipment has been proposed. Utility Model Content

[0004] The purpose of this application is to provide terminal hot melt crimping equipment that can achieve efficient coordination and precise connection between crimping and hot melt processes, thus solving the problems in the background art.

[0005] The terminal hot melt crimping equipment provided in this application adopts the following technical solution: The terminal hot melt crimping equipment includes a base plate, a positioning component, a crimping component, and a hot melt solder component. The positioning component includes a cavity opened inside the base plate. A rotatable one-way lead screw is installed inside the cavity. A sleeve block is threadedly connected to the outer surface of the one-way lead screw. The sleeve block is slidably sleeved on the inner wall of the cavity. A servo motor is fixedly connected to one side of the base plate. The output shaft end of the servo motor is fixedly connected to the rotating shaft end of the one-way lead screw.

[0006] The upper surface of the sleeve is equipped with a detachable positioning base. The upper surface of the positioning base is provided with a groove and a wire groove. Two movable adjustment plates are installed on the inner wall of the groove. C-shaped rods are fixedly connected to the ends of the two adjustment plates that are far apart from each other. The two C-shaped rods are slidably sleeved on both sides of the groove.

[0007] By adopting the above technical solution, the servo motor drives the unidirectional lead screw to rotate, which can drive the sleeve block to slide stably along the cavity, thereby realizing the precise movement of the positioning base and ensuring the stability of the terminal and cable position during processing. The groove and wire groove on the positioning base can respectively provide initial positioning for the terminal and cable. The two movable adjustment plates can flexibly adjust the spacing according to the terminal specifications through the sliding cooperation of the C-shaped rod, so as to achieve stable clamping of terminals of different sizes. This solves the problems of poor adaptability and unstable positioning of traditional positioning structures, and provides a reliable basic positioning for subsequent crimping and hot melt soldering processes.

[0008] Preferably, the crimping assembly is mounted on one end of the upper surface of the base plate, and the hot melt solder assembly includes a first electric slide rail fixedly connected to the upper surface of the base plate, and a second electric slide rail is mounted on the output end of the first electric slide rail.

[0009] By adopting the above technical solution, the crimping component and the hot melt soldering component are set separately on the base plate, realizing the physical separation of the crimping and hot melt soldering processes and avoiding mutual interference between the two processes in a single processing. The cooperation of the first electric slide rail and the second electric slide rail can drive the working parts of the hot melt soldering component to move flexibly, making it easy to adjust the working point according to the processing position of the terminal. Compared with the fixed position processing structure, it greatly improves the equipment's adaptability to different processing requirements and makes the operation more flexible.

[0010] Preferably, a moving block is installed at the output end of the second electric slide rail, a precision soldering gun head is installed on one side of the moving block, and a solder wire feed head is installed at the bottom of the moving block. The positions of the crimping assembly and the hot melt solder assembly correspond to the positions of the positioning assembly.

[0011] By adopting the above technical solution, the moving block can drive the precision soldering gun head and the solder wire feeding head to move synchronously under the drive of the second electric slide rail, ensuring that the gun head can be accurately aligned with the area to be soldered in the middle of the terminal, and the solder wire feeding head can replenish the solder in time, realizing continuous and stable operation of the hot melt soldering process; at the same time, the positions of the crimping component and the hot melt soldering component correspond to the positioning component, ensuring that the crimped terminal can be accurately moved to the hot melt soldering station, reducing processing defects caused by position deviation, and improving the conductivity and structural rigidity of the terminal and cable connection.

[0012] Preferably, a control component is provided on one side of the hot melt solder assembly. The control component includes a bracket fixedly connected to the upper surface of the base plate. One end of the bracket is fixedly connected to the outer surface of the first electric slide rail. A controller is fixedly connected to the inner wall of the bracket. The positioning component, the pressing component, and the electrical components inside the hot melt solder assembly are all electrically connected to the controller.

[0013] By adopting the above technical solution, the control components are fixed to the equipment via a bracket. The controller is electrically connected to the electrical components of the positioning, pressing, and hot-melt soldering components, enabling centralized control and coordinated operation of the working status of each component. Operators can uniformly set parameters and start or stop each process through the controller, improving the automation level and processing efficiency of the equipment.

[0014] Preferably, the base plate has pre-drilled holes at all four corners, and an anti-slip pad is fixedly connected to the bottom surface of the base plate.

[0015] By adopting the above technical solution, the reserved holes at the corners of the base plate facilitate the fixing of the equipment to the workbench or ground with bolts and other connectors, preventing the equipment from shifting due to vibration during operation; the anti-slip pads on the bottom of the base plate increase the friction between the equipment and the placement surface, further enhancing the stability of the equipment placement, avoiding shaking during processing that could affect the positioning accuracy and processing quality of terminals and cables, and improving the overall reliability of the equipment during operation.

[0016] Preferably, a fixing frame is fixedly connected to the outer surface of the two positioning bases, and a rotatable bidirectional lead screw is installed on the inner wall of the fixing frame, with the middle section of the bidirectional lead screw rotatably sleeved in the inner wall of the positioning base.

[0017] By adopting the above technical solution, the fixing frame provides stable installation support for the bidirectional lead screw. When the bidirectional lead screw rotates, it can drive the cooperating components to move synchronously in opposite directions, thereby achieving symmetrical adjustment of the two adjustment plates. This adjustment method can ensure that the clamping force of the two adjustment plates on the terminals is uniform, avoiding terminal offset caused by unilateral adjustment. Compared with the unilateral independent adjustment structure, it can better ensure the centered positioning of the terminals in the groove, improving positioning accuracy.

[0018] Preferably, the bottom ends of the two C-shaped rods are fixedly connected to connecting plates, and the two connecting plates are respectively threaded to both ends of the bidirectional lead screw, and the rotating shaft end of the bidirectional lead screw is fixedly connected to a knob.

[0019] By adopting the above technical solution, the connecting plate connects the C-shaped rod and the double-acting screw. When the double-acting screw rotates, the two connecting plates can move in opposite directions along both ends of the double-acting screw, thereby driving the C-shaped rod and the adjusting plate to smoothly adjust the distance. The knob can increase the contact area at the shaft end of the double-acting screw, thus facilitating the rotation of the double-acting screw.

[0020] Preferably, two limiting rods are installed on the inner wall of the cavity, and the two sides of the sleeve block are slidably sleeved on the outer surfaces of the two limiting rods respectively.

[0021] By adopting the above technical solution, the two limiting rods on the inner wall of the cavity guide the sliding of the sleeve block, limiting the movement trajectory of the sleeve block under the drive of the one-way screw, and preventing the sleeve block from radially offset or shaking due to the rotation of the one-way screw. This structure ensures that the positioning component moves smoothly during the station switching process, improves the movement accuracy of the positioning base from the crimping station to the hot melt soldering station, and ensures the accuracy of the subsequent processing position.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This terminal hot melt crimping equipment uses a servo motor to drive a unidirectional lead screw to rotate, causing the sleeve block to slide stably along the cavity. Combined with the guiding action of the limit rod on the sleeve block, it achieves precise switching between the crimping and hot melt soldering stations, avoiding the positional deviations that easily occur with traditional station switching. When the bidirectional lead screw supported by the fixed frame rotates, it connects to a C-shaped rod via a connecting plate, driving the adjustment plate for symmetrical adjustment. Combined with convenient knob operation, it solves the problems of poor adaptability and uneven clamping in traditional positioning structures, ensuring the terminal is centered within the groove. The crimping and hot melt soldering components are separately set on the base plate. The first and second electric slide rails drive the moving block to precisely align the precision soldering gun head with the area to be soldered on the terminal. The solder wire feed head replenishes solder in a timely manner, improving the conductivity of the terminal-to-cable connection. Simultaneously, the controller achieves centralized control of the positioning, crimping, and hot melt soldering components. Reserved holes and anti-slip pads enhance the overall stability of the equipment. Compared with existing technologies, it effectively solves problems such as inaccurate positioning, process interference, and cumbersome operation, comprehensively improving processing quality and efficiency.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: Terminal hot melt crimping equipment, refer to Figure 1 , Figure 2 and Figure 4 The system includes a base plate 1, a positioning assembly 2, a pressing assembly 3, and a hot-melt solder assembly 4. The positioning assembly 2 includes a cavity 201 formed inside the base plate 1. A rotatable one-way lead screw 202 is installed inside the cavity 201. A sleeve 204 is threadedly connected to the outer surface of the one-way lead screw 202. The sleeve 204 is slidably fitted onto the inner wall of the cavity 201. A servo motor 203 is fixedly connected to one side of the base plate 1. The output shaft end of the servo motor 203 is fixed to the rotating shaft end of the one-way lead screw 202. The upper surface of the sleeve 204 is fitted with a detachable positioning base 205. Two limiting rods 214 are installed on the inner wall of the cavity 201. The two sides of the sleeve 204 are slidably fitted onto the outer surfaces of the two limiting rods 214. The two limiting rods 214 on the inner wall of the cavity 201 guide the sliding of the sleeve 204, limiting its movement trajectory under the drive of the one-way lead screw 202, and preventing radial offset or wobbling of the sleeve 204 due to the rotation of the one-way lead screw 202. This structure ensures smooth movement of the positioning assembly 2 during station switching, improves the movement accuracy of the positioning base 205 from the crimping station to the hot melt soldering station, and guarantees the accuracy of subsequent processing positions.

[0033] Reference Figure 2 , Figure 4 and Figure 5The upper surface of the positioning base 205 is provided with a groove 206 and a wire groove 207. Two movable adjustment plates 208 are installed on the inner wall of the groove 206. C-shaped rods 209 are fixedly connected to the ends of the two adjustment plates 208 that are far apart from each other. The two C-shaped rods 209 are slidably sleeved on both sides of the groove 206. A fixing frame 211 is fixedly connected to the outer surface of the two positioning bases 205. A rotatable bidirectional screw 212 is installed on the inner wall of the fixing frame 211. The middle section of the bidirectional screw 212 is rotatably sleeved in the inner wall of the positioning base 205. The fixing frame 211 provides a stable installation support for the bidirectional screw 212. When the bidirectional screw 212 rotates, it can drive the cooperating parts to move synchronously in the opposite direction, thereby realizing the symmetrical adjustment of the two adjustment plates 208. This adjustment method ensures that the clamping force of the two adjustment plates 208 on the terminals is uniform, avoiding terminal offset caused by unilateral adjustment. Compared with the unilateral independent adjustment structure, it can better ensure the centered positioning of the terminals in the groove 206, improving the positioning accuracy. The bottom ends of the two C-shaped rods 209 are fixedly connected to the connecting plates 210, which are threaded to both ends of the bidirectional lead screw 212. The rotating shaft end of the bidirectional lead screw 212 is fixedly connected to the knob 213. The connecting plates 210 connect the C-shaped rods 209 and the bidirectional lead screw 212. When the bidirectional lead screw 212 rotates, the two connecting plates 210 can move in opposite directions along both ends of the bidirectional lead screw 212, thereby driving the C-shaped rods 209 and the adjustment plates 208 to smoothly adjust the spacing. The knob 213 can increase the contact area of ​​the rotating shaft end of the bidirectional lead screw 212, thus facilitating the rotation of the bidirectional lead screw 212.

[0034] Example 2: Terminal hot melt crimping equipment, refer to Figure 1 , Figure 2 and Figure 3Based on the same concept as Embodiment 1 above, this embodiment proposes that the crimping assembly 3 is installed at one end of the upper surface of the base plate 1, and the hot melt solder assembly 4 includes a first electric slide rail 401 fixedly connected to the upper surface of the base plate 1. A second electric slide rail 402 is installed at the output end of the first electric slide rail 401. The crimping assembly 3 and the hot melt solder assembly 4 are separately set on the base plate 1, realizing the physical separation of the crimping and hot melt soldering processes, avoiding mutual interference between the two processes in a single processing. The cooperation of the first electric slide rail 401 and the second electric slide rail 402 can drive the working parts of the hot melt solder assembly 4 to move flexibly, making it easy to adjust the working point according to the processing position of the terminal. Compared with the fixed position processing structure, it greatly improves the adaptability of the equipment to different processing requirements, and the operation is more flexible. The output of the second electric slide rail 402 is... A movable block 403 is installed at the output end, and a precision soldering gun head 404 is installed on one side of the movable block 403. A solder wire feed head 405 is installed at the bottom of the movable block 403. The positions of the crimping component 3 and the hot melt soldering component 4 correspond to the positions of the positioning component 2. Driven by the second electric slide rail 402, the movable block 403 can drive the precision soldering gun head 404 and the solder wire feed head 405 to move synchronously, ensuring that the gun head can accurately align with the soldering area in the middle of the terminal. The solder wire feed head 405 can replenish the solder in time, realizing continuous and stable operation of the hot melt soldering process. At the same time, the positions of the crimping component 3 and the hot melt soldering component 4 correspond to the positioning component 2, ensuring that the crimped terminal can be accurately moved to the hot melt soldering station, reducing processing defects caused by position deviation, and improving the conductivity and structural rigidity of the terminal and cable connection.

[0035] Reference Figure 1 , Figure 2 and Figure 3A control component 5 is provided on one side of the hot melt solder assembly 4. The control component 5 includes a bracket 501 fixedly connected to the upper surface of the base plate 1. One end of the bracket 501 is fixedly connected to the outer surface of the first electric slide rail 401. A controller 502 is fixedly connected to the inner wall of the bracket 501. The electrical components inside the positioning assembly 2, the pressing assembly 3, and the hot melt solder assembly 4 are all electrically connected to the controller 502. The control component 5 is fixed to the equipment through the bracket 501. The controller 502 is electrically connected to the electrical components of the positioning assembly 2, the pressing assembly 3, and the hot melt solder assembly 4, realizing centralized control and coordinated linkage of the working status of each component. Operators can uniformly set parameters and start or stop each process through the controller 502, which improves the automation level and processing efficiency of the equipment. The four corners of the base plate 1 are provided with reserved holes 6. The bottom surface of the base plate 1 is fixedly connected with anti-slip pads 7. The reserved holes 6 at the corners of the base plate 1 facilitate the fixing of the equipment to the workbench or the ground with bolts or other connecting parts, preventing the equipment from shifting due to vibration during operation. The anti-slip pads 7 on the bottom surface of the base plate 1 can increase the friction between the equipment and the placement surface, further enhancing the stability of the equipment placement, avoiding shaking during processing that affects the positioning accuracy and processing quality of terminals and cables, and improving the overall reliability of the equipment during operation.

[0036] The implementation principle of this application embodiment is as follows: First, by rotating the knob 213, the bidirectional lead screw 212 is driven to rotate within the fixed frame 211. Since the threads at both ends of the bidirectional lead screw 212 are opposite, its rotation will drive the threaded connecting plate 210 to move synchronously in the opposite direction. The connecting plate 210 then pulls the C-shaped rod 209, causing the two adjusting plates 208 to slide along the inner wall of the groove 206 of the positioning base 205 until the spacing between the adjusting plates 208 matches the size of the terminal to be processed. Then, the terminal is placed in the groove 206, and the cable is correspondingly embedded in the wire groove 207 of the positioning base 205, thus completing the workpiece loading and preliminary positioning. Next, the device is started by the controller 502. The controller 502 first controls the servo motor 203 to run. The output shaft of the servo motor 203 drives the one-way lead screw 202 to rotate in the cavity 201 of the base plate 1. The sleeve block 204, which is threadedly connected to the one-way lead screw 202, slides stably under the guidance and restriction of the inner wall of the cavity 201 and the limit rod 214. The positioning base 205 above the sleeve block 204 moves accordingly until the workpiece is precisely aligned with the bottom of the crimping assembly 3. At this time, the crimping assembly 3 completes the initial crimping and fixing of the terminal and the cable. After crimping is completed, the servo motor 203 restarts, driving the positioning base 205 to move below the hot melt solder assembly 4. The controller 502 simultaneously controls the first and second electric slide rails 401 and 402 to move, causing the moving block 403 to adjust its position, ensuring the precision soldering gun head 404 is precisely aligned with the tinning area in the center of the terminal. Simultaneously, the solder wire feed head 405 delivers solder, heating and melting the solder to complete the hot melt soldering in the center of the terminal, enhancing the conductivity and structural rigidity of the terminal and cable. After hot melt soldering is complete, the servo motor 203 drives the positioning base 205 back to the initial loading position. The operator then removes the processed terminal cable assembly, allowing the next processing cycle to begin.
