Description

Technical Field

[0001] This application relates to the field of electronic device manufacturing technology, and in particular to a terminal crimping device. Background Technology

[0002] In the field of electronic equipment manufacturing, terminal crimping machines are key equipment used to crimp metal terminals onto wires or data cables. With the miniaturization and increasing performance of electronic devices, the quality requirements for terminal crimping are becoming increasingly stringent.

[0003] Traditional terminal crimping machines typically use rectangular or triangular cutters for crimping, which, while meeting basic requirements, has limitations in terms of crimp strength and consistency. In recent years, with the widespread adoption of automated production, higher demands have been placed on the precision and efficiency of terminal crimping equipment, prompting continuous improvements in related technologies.

[0004] The contact area between the terminal and the wire is insufficient after crimping with a rectangular cutter, resulting in a weak crimp. The triangular cutter has poor adaptability to terminal materials, which can easily cause terminal deformation or breakage. In addition, metal powder is generated during the crimping process, and the residue of metal powder may cause short circuits in the internal circuits of the equipment or jamming of mechanical parts. In order to solve the above problems, a terminal crimping device is proposed. Utility Model Content

[0005] The purpose of this application is to provide a terminal crimping device that changes the shape of the terminal machine cutter to an elliptical shape, which can crimp the terminals more firmly. At the same time, an adsorption component is added at an appropriate position, which solves the problems mentioned in the background art.

[0006] The terminal crimping device provided in this application adopts the following technical solution: A terminal crimping device includes a base frame, a crimping machine body, a positioning component, a receiving component, and an adsorption component. The output end of the crimping machine body is equipped with a detachable elliptical cutter. The receiving component includes a receiving plate and a base and a fixing plate fixedly connected to the upper surface of the receiving plate. The inner wall of the fixing plate is provided with uniformly distributed adsorption holes, and the inner wall of each adsorption hole is coated with a conductive silicone layer.

[0007] The adsorption assembly includes an adsorption collection box fixedly connected to the upper surface of the base frame. A negative pressure fan is installed at the bottom of the adsorption collection box. A collection frame is slidably fitted inside the adsorption collection box. A magnetic mesh plate and a filter cloth are installed on the inner wall of the collection frame. The magnetic mesh plate is located above the filter cloth. A negative pressure hose is connected to the top of the adsorption collection box. The output end of the negative pressure hose is connected to an adsorption cover. The adsorption cover is positioned on the back of the fixing plate by bolts.

[0008] By adopting the above technical solutions, the elliptical contour of the elliptical cutter can evenly distribute the crimping force during crimping, significantly increasing the contact area between the terminal and the wire. Compared with traditional rectangular / triangular cutters, the crimping firmness is improved. The detachable installation design facilitates the replacement of cutters according to different terminal specifications, enhancing the adaptability of the equipment. The adsorption holes in the receiving component are connected to the adsorption component, which can adsorb metal powder in time during the crimping process through negative pressure, avoiding powder accumulation that affects the terminal positioning accuracy and extending the service life of the device. The conductive silicone layer covering the inner wall of the adsorption holes can prevent electrostatic adsorption of powder residue, further ensuring the cleanliness of the crimping station. The negative pressure fan in the adsorption component forms an airflow circulation through the negative pressure hose and the adsorption cover, quickly sucking the powder generated during crimping into the adsorption collection box. The magnetic mesh plate and filter cloth provide dual filtration, which can effectively separate metal powder from the airflow, preventing powder from clogging the equipment or causing circuit failures.

[0009] Preferably, the positioning component includes a positioning plate fixedly connected to the upper surface of the base frame, the upper surface of the positioning plate is provided with a sliding groove, and a positioning block is slidably sleeved on the inner wall of the sliding groove.

[0010] By adopting the above technical solution, the sliding groove on the positioning plate and the positioning block slide together, and the position of the positioning block can be flexibly adjusted to achieve accurate positioning of the terminal crimping position, avoiding poor crimping caused by positioning deviation.

[0011] Preferably, a lead screw is rotatably sleeved on the inner wall of the slide, the positioning block is threadedly connected to the lead screw, and a knob is fixedly connected to the rotating shaft end of the lead screw.

[0012] By adopting the above technical solution, the lead screw and the positioning block are threadedly connected. Turning the knob can drive the lead screw to rotate, which in turn drives the positioning block to move smoothly along the slide. The operation is convenient and the positioning accuracy is high, which is suitable for crimping requirements of terminals of different specifications.

[0013] Preferably, a wedge-shaped stop is fixedly connected to one end of the positioning plate, the wedge-shaped stop is adapted to one end of the receiving plate, and the receiving plate is positioned on the upper surface of the positioning plate by the positioning block and the wedge-shaped stop.

[0014] By adopting the above technical solution, the wedge-shaped stop is adapted to the receiving plate. Through the dual limiting of the positioning block and the wedge-shaped stop, the receiving plate can be firmly fixed on the positioning plate, preventing the receiving component from shaking during pressing and ensuring the stability of the pressing process.

[0015] Preferably, the crimping machine body is fixedly connected to the upper surface of the base frame, and the adsorption collection box is located below the crimping machine body.

[0016] By adopting the above technical solution, the main body of the crimping machine is fixed above the base frame, and the adsorption collection box is located below the main body of the crimping machine. This shortens the adsorption path, maximizes the negative pressure adsorption efficiency, ensures that the powder is collected immediately after it is generated, and reduces powder diffusion pollution.

[0017] Preferably, a guide strip is fixedly connected to the inner wall of the adsorption collection box, and the guide strip is slidably connected to the bottom end of the collection frame.

[0018] By adopting the above technical solution, the guide strip on the inner wall of the base frame is slidably connected to the collection frame, which makes it easy to pull out the collection frame to clean the powder, simplifying maintenance and reducing equipment downtime for maintenance.

[0019] Preferably, the output ends of the plurality of adsorption holes are all located inside the adsorption cover.

[0020] By adopting the above technical solution, the adsorption holes are evenly distributed on the inner wall of the fixed plate and connected to the adsorption cover, which can form a large area of ​​negative pressure adsorption area, covering the entire crimping station, ensuring that the powder is collected without dead corners and avoiding powder residue in the terminal positioning area.

[0021] Preferably, a lighting lamp is installed on the outside of the crimping machine body.

[0022] By adopting the above technical solution, the lighting is installed on the outside of the crimping machine body, which can illuminate the crimping station, making it easier for operators to observe the terminal positioning status and crimping process, and promptly detect abnormalities such as terminal misalignment and powder accumulation, thereby improving the controllability of crimping quality.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] This terminal crimping device uses an elliptical cutter to evenly distribute the crimping force during crimping, significantly increasing the contact area between the terminal and the wire. Compared to traditional cutters, this improves crimping firmness. Its detachable design allows for easy replacement of the cutter according to different terminal specifications, enhancing adaptability. The device connects to the adsorption assembly via adsorption holes in the receiving component. During crimping, a negative pressure fan, through a negative pressure hose and adsorption hood, forms an airflow that promptly adsorbs metal powder. Combined with the magnetic mesh plate and filter cloth in the adsorption collection box, dual filtration prevents powder accumulation from affecting terminal positioning accuracy, clogging the equipment, or causing circuit failures. A conductive silicone layer covering the inner wall of the adsorption holes prevents electrostatic adsorption of powder residue. The adsorption collection box is located below the crimping machine body, shortening the adsorption path and improving negative pressure adsorption efficiency. The positioning component allows for convenient positioning of the receiving component below the crimping machine body, preventing shaking during crimping. Overall, this device solves problems such as weak crimping, easy terminal deformation, powder contamination of the equipment, and positioning deviations in existing technologies. It features a simple structure, high crimping accuracy, strong adaptability, and convenient maintenance. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0033] Example 1: A terminal crimping device includes a base frame 1, a crimping machine body 2, a positioning component 3, a receiving component 4, and an adsorption component 5. The output end of the crimping machine body 2 is equipped with a detachable elliptical cutter 6. The receiving component 4 includes a receiving plate 401 and a base 402 and a fixing plate 403 fixedly connected to the upper surface of the receiving plate 401. The inner wall of the fixing plate 403 is provided with uniformly distributed adsorption holes 404. The inner wall of each adsorption hole 404 is coated with a conductive silicone layer 405. The conductive silicone layer 405 can prevent electrostatic adsorption powder from remaining in the inner wall of the adsorption hole 404, thereby optimizing the adsorption effect of metal powder.

[0034] The adsorption assembly 5 includes an adsorption collection box 501 fixedly connected to the upper surface of the base frame 1. The crimping machine body 2 is fixedly connected to the upper surface of the base frame 1, and the adsorption collection box 501 is located below the crimping machine body 2. The crimping machine body 2 is fixed above the base frame 1, and the adsorption collection box 501 is located below the crimping machine body 2, which shortens the adsorption path, maximizes the negative pressure adsorption efficiency, ensures that the powder is collected immediately after it is generated, and reduces powder diffusion pollution. A negative pressure fan 502 is installed at the bottom of the adsorption collection box 501. When the negative pressure fan 502 is started, it can generate negative pressure suction inside the adsorption collection box 501. The suction force is not too large. The generated suction force can adsorb the metal powder generated during the crimping process, but will not affect the crimping process of terminals and data cables. A collection frame 503 is slidably sleeved inside the adsorption collection box 501.

[0035] The inner wall of the collection frame 503 is equipped with a magnetic mesh plate 505 and a filter cloth 506. The magnetic mesh plate 505 is located above the filter cloth 506. The inner wall of the adsorption collection box 501 is fixedly connected with a guide strip 504. The guide strip 504 is slidably connected to the bottom end of the collection frame 503. The guide strip 504 on the inner wall of the base frame 1 is slidably connected to the collection frame 503, which facilitates the removal of the collection frame 503 to clean the powder. The maintenance operation is simple and can reduce the downtime of equipment maintenance. The top of the adsorption collection box 501 is connected to a negative pressure hose 507. The output end of the negative pressure hose 507 is connected to an adsorption cover 508. The adsorption cover 508 is positioned on the back of the fixing plate 403 by bolts. The output ends of multiple adsorption holes 404 are all located inside the adsorption cover 508. The adsorption holes 404 are evenly distributed on the inner wall of the fixing plate 403 and connected to the adsorption cover 508, which can form a large area of ​​negative pressure adsorption area, covering the entire pressing station, ensuring that the powder is collected without dead corners and avoiding powder residue in the terminal positioning area.

[0036] Example 2: A terminal crimping device, based on the same concept as Example 1 above, this example proposes a positioning component 3 including a positioning plate 301 fixedly connected to the upper surface of the base frame 1. The upper surface of the positioning plate 301 is provided with a sliding groove 302, and a positioning block 304 is slidably sleeved on the inner wall of the sliding groove 302. The sliding groove 302 on the positioning plate 301 and the positioning block 304 are slidably engaged, and the position of the positioning block 304 can be flexibly adjusted to achieve accurate positioning of the terminal crimping position, avoiding poor crimping caused by positioning deviation. A lead screw 303 is rotatably sleeved on the inner wall of the sliding groove 302, and the positioning block 304 is threadedly connected to the lead screw 303. A knob 306 is fixedly connected to the rotating shaft end of the lead screw 303. The lead screw 303 and the positioning block 304 are threadedly connected. Rotating the knob 306 can drive the lead screw 303 to rotate, causing the positioning block 304 to move smoothly along the sliding groove 302. The operation is convenient and the positioning accuracy is high, which is suitable for the crimping needs of terminals of different specifications.

[0037] A wedge-shaped stop 305 is fixedly connected to one end of the positioning plate 301. The wedge-shaped stop 305 is adapted to one end of the receiving plate 401. The receiving plate 401 is positioned on the upper surface of the positioning plate 301 by the positioning block 304 and the wedge-shaped stop 305. The wedge-shaped stop 305 is adapted to the receiving plate 401. Through the double limiting of the positioning block 304 and the wedge-shaped stop 305, the receiving plate 401 can be firmly fixed on the positioning plate 301 to prevent the receiving component 4 from shaking during crimping and to ensure the stability of the crimping process. An illumination lamp 7 is installed on the outside of the crimping machine body 2. The illumination lamp 7 is installed on the outside of the crimping machine body 2 to illuminate the crimping station, making it easier for the operator to observe the terminal positioning status and crimping process, and to detect abnormalities such as terminal offset and powder accumulation in time, thereby improving the controllability of crimping quality.

[0038] The implementation principle of this application embodiment is as follows: First, the terminal and data cable are placed on the base 402 of the receiving component 4, and precise positioning is achieved through the positioning component 3. Rotating the knob 306 drives the lead screw 303 to rotate, causing the positioning block 304 to slide along the groove 302 of the positioning plate 301. After adjusting to the appropriate position, the receiving plate 401 is firmly fixed on the positioning plate 301 using the double limiting of the wedge-shaped stop 305 and the positioning block 304, ensuring accurate terminal crimping. During crimping, the crimping machine body 2 drives the detachable elliptical cutter 6 downwards. After its elliptical contour contacts the terminal, the crimping force is evenly distributed, allowing the terminal and wire to form a larger contact area, achieving a firm crimp. During the crimping process, the adsorption assembly 5 starts simultaneously. The negative pressure fan 502 forms an airflow circulation with the adsorption hood 508 through the negative pressure hose 507. The adsorption holes 404 evenly distributed on the inner wall of the fixed plate 403 suck in the metal powder generated during crimping. The conductive silicone layer 405 coated on the inner wall prevents electrostatic adsorption of powder residue. The powder enters the adsorption collection box 501 through the adsorption hood 508 and is stored in the collection frame 503 after double filtration by the magnetic mesh plate 505 and the filter cloth 506. Since the adsorption collection box 501 is located below the crimping machine body 2, the adsorption path is shortened, improving the powder collection efficiency. In addition, the external lighting 7 of the crimping machine body 2 illuminates the crimping station, making it easy for operators to observe the terminal positioning status and crimping process in real time and detect abnormalities in a timely manner. When it is necessary to clean the powder, the collection frame 503 can be pulled out along the guide strip 504 to complete the maintenance. The entire equipment achieves integrated operation of precise crimping, powder cleaning and convenient maintenance through the coordinated work of various components.
