Description

Technical Field

[0001] This application relates to the field of wire harness processing technology, and more specifically, to a lower housing mounting mechanism. Background Technology

[0002] In the fields of wire processing and electronic connector manufacturing, after the terminals are riveted to the ends of the wires, they need to be assembled with the lower housing of the connector to form a complete connection assembly. The precise assembly of the lower housing and the terminals is a key step in ensuring connector performance. Currently, this assembly process still relies on manual operation in most production scenarios: operators need to manually take the lower housing from the material box and place it on a simple tooling table, then hold the wire with the riveted terminals and visually align the terminals with the mounting slots of the lower housing, and then manually press to complete the assembly.

[0003] The existing technology for manually installing the lower housing has low positioning accuracy. It is easy for visual fatigue or operational deviations to cause misalignment between the terminal and the lower housing, resulting in terminal bending, core wire damage, or even deformation of the lower housing, which affects the stability of product quality. In addition, it is labor-intensive and leads to low production efficiency. Utility Model Content

[0004] To address the aforementioned problems, this application provides a lower housing mounting mechanism.

[0005] The lower housing mounting mechanism provided in this application adopts the following technical solution:

[0006] A lower housing mounting mechanism includes a base plate, a Y-axis linear module on the top of the base plate, a connecting seat slidably fitted on the top of the Y-axis linear module, and a mounting component above the connecting seat.

[0007] The mounting assembly includes a placement component and a crimping component. The placement component includes a placement seat mounted on a connector. The top of the placement seat has a positioning groove that matches the shape of the lower housing. The size of the positioning groove is adapted to the outer contour of the lower housing for placing the lower housing.

[0008] The crimping component includes a wire crimping block and a terminal crimping block fixedly mounted on the connector. The wire crimping block is used to crimp the wire on the lower housing, and the terminal crimping block is used to crimp the terminal on the lower housing. The crimping surfaces of the wire crimping block and the terminal crimping block correspond to the contact areas of the wire and the terminal, respectively.

[0009] Through the above technical solutions, the guiding and screening of the lower housing vibratory plate, the cooperation between the material suction cup and the positioning groove, and the visual positioning-assisted lower gripper for aligning and pushing the core wire terminals, the positioning accuracy is improved, and the terminal bending, core wire damage and lower housing deformation caused by operational deviations are reduced, ensuring stable product quality. At the same time, the entire installation process is automated, eliminating the need for repetitive manual operations, reducing labor intensity and improving production efficiency.

[0010] Furthermore, an electric slide rail is installed on the top of the connecting seat, and a sliding plate is slidably engaged at one end of the electric slide rail.

[0011] Furthermore, a movable electric cylinder is fixedly connected to the front side of the slide, and a material-picking suction cup is connected to the output end of the movable electric cylinder.

[0012] Furthermore, a placement frame is fixedly connected to one end of the skateboard, and two crimping electric cylinders are installed inside the placement frame.

[0013] Furthermore, the output ends of the two crimping cylinders are connected to the crimping block and the crimping terminal block, respectively.

[0014] Furthermore, a clamping electric cylinder is installed on the top of the base plate, and a gripper is connected to the front end of the clamping electric cylinder.

[0015] Furthermore, the grippers are located on one side of the placement seat.

[0016] Furthermore, the top of the base plate is equipped with two lower rubber shell vibrating plates, and one end of each of the two lower rubber shell vibrating plates is equipped with a conveying track.

[0017] Furthermore, each conveyor track has a material collection point at its discharge end.

[0018] Furthermore, the crimping block and crimping terminal block are detachably connected to the corresponding crimping electric cylinder.

[0019] With the above technical solution, when it is necessary to process core wires, terminals or lower housings of different specifications and shapes, it is not necessary to replace the entire crimping cylinder. Only the matching crimping block and crimping terminal block need to be replaced according to the new product parameters. This reduces the modification cost and time of the equipment, enables the mechanism to quickly switch production models, and improves the versatility and flexibility of the equipment.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] This invention improves positioning accuracy and reduces terminal bending, core wire damage, and lower shell deformation caused by operational deviations by using a lower shell vibratory plate for guiding and screening, a material suction cup and positioning groove, and a visual positioning-assisted lower gripper to align and push the core wire terminals. This ensures stable product quality. At the same time, the entire installation process is automated, eliminating the need for repetitive manual operations, reducing labor intensity, and improving production efficiency.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Reference Figures 1-6 A lower housing mounting mechanism includes a base plate 1, a Y-axis linear module 2 is provided on the top of the base plate 1, a connecting seat 3 is slidably fitted on the top of the Y-axis linear module 2, and a mounting component is provided above the connecting seat 3.

[0031] The mounting assembly includes a placement component and a pressing component. The placement component includes a placement seat 15 mounted on the connecting seat 3. The top of the placement seat 15 has a positioning groove 17 that matches the shape of the lower rubber shell. The size of the positioning groove 17 is adapted to the outer contour of the lower rubber shell for placing the lower rubber shell.

[0032] The crimping component includes a wire crimping block 10 and a terminal crimping block 11 fixedly mounted on the connector 3. The wire crimping block 10 is used to crimp the wire on the lower housing, and the terminal crimping block 11 is used to crimp the terminal on the lower housing. The crimping surfaces of the wire crimping block 10 and the terminal crimping block 11 correspond to the contact areas of the wire and the terminal, respectively.

[0033] Two lower rubber shell vibratory plates 4 are responsible for conveying the female and male lower rubber shells respectively. One vibratory plate conveys the female lower rubber shell and the other conveys the male lower rubber shell. One of the lower rubber shell vibratory plates 4 is selected to operate according to the processing needs.

[0034] High-frequency vibration causes the lower plastic shell inside to move orderly along the conveyor track. After being guided and screened by the track, the lower plastic shell is conveyed to the material picking position 5 at the end of the conveyor track in a preset posture. After the sensor at the material picking position 5 detects that the lower plastic shell has arrived, it sends a signal to the external control system (existing technology, not shown in the figure). The control system drives the electric slide rail 6 to run, which drives the slide plate 7 to move along the slide rail direction. When the material picking suction cup 16 moves to directly above the material picking position 5, the electric slide rail 6 stops. At this time, the output end of the moving electric cylinder 8 extends downward to drive the material picking. The suction cup 16 approaches and contacts the lower plastic shell, generating negative pressure inside the suction cup to firmly hold the lower plastic shell in place. Then, the output end of the moving electric cylinder 8 retracts and resets, and the electric slide rail 6 starts again, driving the material-picking suction cup 16 holding the lower plastic shell to move directly above the placement seat 15. Then, the output end of the moving electric cylinder 8 extends again, accurately placing the lower plastic shell into the positioning groove 17 at the top of the placement seat 15 (the shape and size of the positioning groove 17 are perfectly matched with the lower plastic shell to ensure that the lower plastic shell does not shift after being placed). The material-picking suction cup 16 releases the negative pressure, and the output end of the moving electric cylinder 8 retracts and resets.

[0035] At this time, the gripper 14 clamps the core wire terminal. Usually, the clamping center of the gripper 14 is slightly higher than the groove plane of the positioning groove 17, so as to avoid the core wire terminal from rubbing against the edge of the positioning groove 17 during the movement.

[0036] Subsequently, driven by the clamping electric cylinder 13, the gripper 14 moves horizontally toward the positioning groove 17 with the core wire terminal. During the movement, external visual positioning (which is existing technology and not shown in the figure) is used to ensure that the insertion end of the core wire terminal is aligned with the entrance of the lower housing mounting groove. Then, the horizontal advancement continues to smoothly send the core wire terminal into the groove until the preset depth.

[0037] After placement, the electric slide rail 6 drives the slide plate 7 to continue moving, positioning the wire pressing block 10 and the terminal pressing block 11 at the top of the lower housing. At this time, the two crimping cylinders 12 inside the placement frame 9 start synchronously, extending their output ends downwards to push the wire pressing block 10 and the terminal pressing block 11 vertically downwards, respectively. The wire pressing block 10 precisely aligns with the core wire on the lower housing. As the crimping cylinder 12 drives it closer and applies a preset pressure, it firmly presses the core wire into the corresponding slot in the lower housing, preventing the core wire from loosening or shifting in subsequent processes. The terminal pressing block 11 aligns with the terminal inside the lower housing, pressing the terminal further into the mounting groove of the lower housing under pressure, ensuring that the terminal and the snap-fit ​​structure of the lower housing are fully engaged, achieving a secure connection. During the crimping process, the crimping cylinder 12 monitors the pressure value in real time through its built-in sensor. When the pressure reaches a preset threshold, the output end stops moving downwards and maintains the pressure for 1-2 seconds to ensure stable crimping results. Then, the clamping jaws 14 clamp the core wire terminal. Subsequently, the output end of the crimping cylinder 12 retracts and resets, causing the crimping block 10 and the crimping terminal block 11 to move upward away from the lower housing, completing the entire crimping operation. Finally, the clamping cylinder 13 drives the gripper 14 to re-grip the crimped core wire terminal. The gripper 14 moves under the drive of the clamping cylinder 13, removing the core wire terminal from the lower housing and moving it to the designated position, completing the removal operation of the core wire terminal.

[0038] Reference Figures 1-3 An electric slide rail 6 is installed on the top of the connecting seat 3. A slide plate 7 is slidably fitted at one end of the electric slide rail 6. A movable electric cylinder 8 is fixedly connected to the front side of the slide plate 7. A material suction cup 16 is connected to the output end of the movable electric cylinder 8.

[0039] Reference Figures 3-5 One end of the slide plate 7 is fixedly connected to a placement frame 9. The placement frame 9 is equipped with two crimping electric cylinders 12. The output ends of the two crimping electric cylinders 12 are respectively connected to the wire crimping block 10 and the terminal crimping block 11. The wire crimping block 10 and the terminal crimping block 11 are detachably connected to the corresponding crimping electric cylinders 12.

[0040] When processing core wires, terminals, or lower housings of different specifications and shapes, it is not necessary to replace the entire crimping cylinder 12. Only the matching crimping block 10 and crimping terminal block 11 need to be replaced according to the new product parameters. This reduces the modification cost and time of the equipment, enables the mechanism to quickly switch production models, and improves the versatility and flexibility of the equipment. At the same time, the placement seat 15 is also designed as a detachable or replaceable structure. The positioning groove 17 on its top can be customized according to the shape and size of different lower housings. When changing the specifications of the lower housing, only the placement seat 15 with the matching positioning groove 17 needs to be replaced, so that it can work together with the newly replaced crimping block 10 and crimping terminal block 11.

[0041] Reference Figures 3-4A clamping electric cylinder 13 is installed on the top of the base plate 1. A gripper 14 is connected to the front end of the clamping electric cylinder 13. The gripper 14 is located on one side of the placement seat 15.

[0042] Reference Figures 1-2 The top of the base plate 1 is provided with two lower rubber shell vibrating plates 4. One end of each of the two lower rubber shell vibrating plates 4 is provided with a conveying track, and the discharge end of each conveying track is provided with a material picking position 5.

[0043] Working principle: Select the corresponding lower rubber shell vibratory plate 4 according to the processing requirements. The female or male lower rubber shell moves along the conveyor track under the high-frequency vibration of the vibratory plate. After being guided and screened, it reaches the picking position 5 in a preset posture.

[0044] After the sensor at the material picking position 5 (existing technology, not shown in the figure) detects the lower plastic shell, the control system drives the electric slide rail 6 to move the slide plate 7, positioning the material picking suction cup 16 directly above the material picking position 5. The moving electric cylinder 8 drives the suction cup to move downward and generate negative pressure to suck up the lower plastic shell. Then, it resets and is moved by the electric slide rail 6 to directly above the placement seat 15. The moving electric cylinder 8 extends again to place the lower plastic shell into the positioning groove 17. The suction cup releases the negative pressure and resets. At the same time, the clamping electric cylinder 13 drives the gripper 14 to clamp the core wire terminal. The clamping center of the gripper 14 is slightly higher than the opening of the positioning groove 17. During the horizontal movement, visual positioning is used to ensure that the terminal insertion end is aligned with the mounting groove of the lower plastic shell, and the process continues to advance to the preset depth. Afterwards, the electric slide rail 6 drives the slide plate 7 to move, so that the wire pressing block 10 and the terminal pressing block 11 are located at the top of the lower housing. The two crimping cylinders 12 in the placement frame 9 are started simultaneously, pushing the wire pressing block 10 and the terminal pressing block 11 downward, respectively pressing the core wire into the slot and pressing the terminal into the deep mounting slot. The crimping cylinder 12 monitors the pressure through the sensor. After reaching the threshold, it holds for 1-2 seconds, then retracts and resets, driving the wire pressing block 10 and the terminal pressing block 11 to leave, completing the crimping operation. Finally, the clamping cylinder 13 drives the gripper 14 to re-grip the crimped core wire terminal. The gripper 14 moves under the drive of the clamping cylinder 13, taking the core wire terminal out of the lower housing and moving it to the designated position, completing the removal operation of the core wire terminal.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
