Description

Technical Field

[0001] This application relates to the field of automotive connector manufacturing, and more particularly to an automotive connector manufacturing feeding device. Background Technology

[0002] Automotive connectors are key basic components of automotive electrical systems, used to achieve reliable electrical connections and signal transmission between wire harnesses and between wire harnesses and electronic devices; Currently, the production process of automotive connectors follows the sequence of injection molding, material supply and matching, and assembly and testing. After the injection molded parts are cooled and demolded, they enter the material supply stage. The material supply device arranges the bushings and terminals in sequence and transports them to the assembly station to achieve precise material supply and buffering. Finally, the assembly process is carried out. The terminals are pressed into the housing, the seals are installed, and the secondary locking structure is fastened through equipment such as cam insertion machines and automatic pin insertion machines to complete the assembly of the connector body.

[0003] However, when traditional feeding devices are used, the feeding, buffering, positioning and assembly of bushings and terminals are mostly carried out in a decentralized operation mode. The various links lack efficient collaborative design and are difficult to match the high efficiency and precision requirements of modern production lines.

[0004] To address these issues, we propose a material supply device for automotive connector production. Summary of the Invention

[0005] To address the lack of efficient collaborative design in various stages of traditional automotive connector production, which makes it difficult to meet the demands of high efficiency and precision in modern production lines, this application provides an automotive connector production feeding device.

[0006] The technical solution of the automotive connector manufacturing feeding device provided in this application is as follows: A feeding device for automotive connector manufacturing, comprising: A support frame, wherein a support frame A is fixedly connected to the top of the support frame, and a feeding mechanism is assembled at the top of the support frame A; An extension frame is fixedly connected to one side of a support frame. A bushing feeder is fixedly connected to the top of the extension frame. A material guiding assembly is provided between the bushing feeder and the feeding mechanism. A conveying assembly A is assembled at the top of the support frame. The feeding mechanism is used to cooperate with the material guiding assembly to transfer the bushing to the conveying assembly A. A terminal feeding assembly is mounted on the top of the support frame at the end away from the conveying assembly A, and a conveying assembly B is mounted on the end of the support frame near the terminal feeding assembly. The terminal feeding assembly is used to transfer terminals to the conveying assembly B. A loading assembly is assembled between conveying assembly A and conveying assembly B, and the loading assembly is used to transfer the bushing between conveying assembly A and conveying assembly B.

[0007] By adopting the above technical solutions, the collaborative feeding of terminals and bushings can be achieved, the accuracy of terminal and bushing feeding can be improved, and the product processing quality can be guaranteed.

[0008] Optionally, the feeding assembly includes: The upright plate is fixedly connected to the top of the support frame near the end of the bushing feeder. A guide plate is fixedly connected to the top of the upright plate. A material guiding channel is opened at the top of the guide plate and the material guiding channel is connected to the discharge end of the bushing feeder. A feeding cylinder is fixedly connected to one side of the vertical plate. A push plate A is fixedly connected to the output end of the feeding cylinder. Push rods for pushing bushings are fixedly connected to both ends of the push plate A.

[0009] By adopting the above technical solution, the bushings are sequentially fed to the feeding channel by the bushing feeder, and the bushings are adjusted along the feeding channel. When the foremost bushing reaches above the push rod, the feeding cylinder is activated to push the push plate A upward, so that the push rod approaches the foremost bushing. As the push rod contacts the bushing, it can lift the foremost bushing.

[0010] Optionally, the feeding mechanism includes: A support frame A is fixedly connected to the top of a bearing frame A. A transmission screw A is rotatably connected to the inner side of the support frame A. A transmission motor A is fixedly connected to one end of the support frame A, and the output end of the transmission motor A is also fixedly connected to the transmission screw A. A displacement frame A is threadedly connected to the outside of a transmission screw A. A transmission cylinder A is fixedly connected to one side of the displacement frame A. An adjustment frame A is fixedly connected to the output end of the transmission cylinder A. A settling frame is fixedly connected to one side of the adjustment frame A. A pneumatic gripper A is fixedly connected to one side of the settling frame for gripping the bushing.

[0011] By adopting the above technical solution, the transmission screw A is driven to rotate by the transmission motor A. With the connection between the transmission screw A and the displacement frame A, the displacement frame A can be adjusted along the transmission screw A until the pneumatic gripper A reaches the bushing above the push rod. Then, the transmission cylinder A is activated to push the placement frame downward and the pneumatic gripper A removes the bushing from the push rod.

[0012] Optionally, the conveying component A includes: The positioning plate is fixedly connected to one end of the top of the support frame near the vertical plate. The top of the positioning plate is vertically rotatably connected to a central shaft. The top of the central shaft is fixedly connected to a settling plate. The top of the settling plate is fixedly connected to multiple feeding columns. A positioning seat is fixedly connected to one side of the positioning disk. A drive motor is fixedly connected to the top of the positioning seat. A transmission spur gear is fixedly connected to the output end of the drive motor. A reduction spur gear is fixedly connected to the outer side of the central shaft, and the reduction spur gear is also meshed with the transmission spur gear.

[0013] By adopting the above technical solution, the drive motor A is started, and in conjunction with the connection between the drive screw A and the displacement frame A, the bushing is adjusted to the feeding column at one end of the placement plate, so that the feeding column can temporarily support the bushing. After the bushings are placed on the feeding columns at one end of the placement plate, the drive motor is started to drive the drive spur gear to rotate, causing the drive spur gear to move the reduction spur gear, and then drive the placement plate to rotate 180 degrees through the central shaft, so that the end of the placement plate with the bushing faces the guide frame, and the end without the bushing reaches the pneumatic gripper A, waiting to place the bushing.

[0014] Optionally, the terminal feeding assembly includes: Two terminal feeders are fixedly connected to the top of the support frame, and the discharge ends of the two terminal feeders are fixedly connected to a feeding rail. Two support frames B are fixedly connected to the top of the support frame, and the two support frames B correspond to two feeding rails respectively. A support frame B is fixedly connected to the top of the support frame B. A transmission screw B is rotatably connected to the inner side of the support frame B. A transmission motor B is fixedly connected to one end of the support frame B, and the output end of the transmission motor B is also fixedly connected to the transmission screw B. A displacement frame B is threaded to the outside of a transmission screw B. A transmission cylinder B is fixedly connected to one side of the displacement frame B. An adjustment frame B is fixedly connected to the output end of the transmission cylinder B. A pneumatic gripper B is fixedly connected to one side of the adjustment frame B for gripping terminals.

[0015] By adopting the above technical solution, the terminal feeder is started to transfer the terminal to the feeding rail, and the drive motor B is started to drive the drive screw B to rotate. With the connection between the drive screw B and the displacement frame B, the displacement frame B can be adjusted along the drive screw B, thereby changing the position of the pneumatic gripper B. When the pneumatic gripper B reaches the top of the terminal at the front of the feeding rail, the drive cylinder B is started to push the adjustment frame B downward and the terminal is gripped by the pneumatic gripper B. Then, with the help of the adjustment of the displacement frame B along the drive screw B, the terminal is transferred to the base on one of the trays.

[0016] Optionally, the loading component includes: Two columns are fixedly connected to the top of the support frame, and a carrier plate is fixedly connected between the tops of the two columns. Support blocks are fixedly connected to both ends of the carrier plate. A transmission screw C is rotatably connected between two support blocks. A transmission motor C is fixedly connected to one side of one of the support blocks, and the output end of the transmission motor C is also fixedly connected to the transmission screw C. A displacement frame C is threaded to the outside of a transmission screw C. A transmission cylinder C is fixedly connected to one side of the displacement frame C. A guide frame is fixedly connected to the output end of the transmission cylinder C. Multiple pneumatic grippers C are fixedly connected to the bottom end of the guide frame for gripping the bushing.

[0017] By adopting the above technical solution, the drive motor C is started to drive the drive screw C to rotate. With the connection between the drive screw C and the displacement frame C, the displacement frame C can be adjusted along the drive screw C, thereby changing the position of the pneumatic gripper C. When the pneumatic gripper C reaches above the bushing on the placement plate, the drive cylinder C is started to push the guide frame downward and the pneumatic gripper C grabs the bushing on the placement plate. After grabbing, the drive motor C is started to cause the displacement frame C to adjust towards the support plate. When the position of the bushing corresponds to the position of the placement column, the pneumatic gripper C is moved down to place the bushing on the placement column, thereby realizing the feeding of terminals and bushings.

[0018] Optionally, the conveying component B includes: The mounting frame is fixedly connected to the top of the support frame. Two threaded rods are rotatably connected to the inner side of the mounting frame. One end of each threaded rod is fixedly connected to a reversing spur gear, and the two reversing spur gears are meshed together. One end of the mounting frame is fixedly connected to a motor, and the output end of the motor is also fixedly connected to one of the threaded rods. Two transmission frames are threadedly connected to two threaded rods respectively. An adjusting cylinder is fixedly connected to one side of each transmission frame. A support plate is fixedly connected to the output end of the adjusting cylinder. A positioning hole is opened in the middle of the top of the support plate. Multiple placement columns are fixedly connected to the middle of the top of the support plate for placing bushings. Four bases are fixedly connected to the four corners of the top of the tray, and a positioning block is slidably connected to the middle of each base. A support base is fixedly connected to the bottom end of the tray. An electric push rod is fixedly connected to the bottom of the support base. A push frame is fixedly connected to the output end of the electric push rod. Support shafts are fixedly connected to both ends of the push frame. A linkage plate is rotatably connected to both ends of each support shaft. The ends of the four linkage plates away from the support shafts are rotatably connected to four positioning blocks respectively.

[0019] By adopting the above technical solution, the adjusting cylinder at one of the pallets is activated, causing the pallet to be adjusted downwards, creating a height difference between the two pallets. Then, the motor is started, driving the threaded rod connected to it to rotate. With the help of two reversing spur gears, the power of the motor can be transmitted to the other threaded rod, causing the two threaded rods to rotate simultaneously in opposite directions. As a result, one pallet moves away from the reversing spur gear, while the other pallet is adjusted towards the pneumatic gripper B. When one pallet reaches below the pneumatic gripper C, the other pallet will simultaneously reach the pneumatic gripper B. Then, terminals are loaded onto the other pallet via the pneumatic gripper B.

[0020] Optionally, a plug is fixedly connected to the top of the discharge column, and a rubber ring is provided on the outside of the plug.

[0021] By adopting the above technical solution, when the bushing is placed at the top of the discharge column, the insert rod can be moved into the through hole in the middle of the bushing to restrict the bushing and prevent it from falling off the discharge column.

[0022] Optionally, a limiting groove is provided at the bottom of the inner side of the mounting frame, and the bottom of the transmission frame is also slidably connected to the interior of the limiting groove.

[0023] By adopting the above technical solution, the displacement of the transmission frame can be effectively guided, preventing the transmission frame from rotating with the threaded rod and ensuring the stability of the transmission frame during adjustment.

[0024] Optionally, one end of the positioning block is provided with a mounting hole, and the end of the linkage plate away from the support shaft is connected to the inside of the mounting hole via a rotating shaft.

[0025] By adopting the above technical solution and setting the mounting holes, the linkage plate can be stably assembled with the positioning block by means of the rotating shaft, ensuring the stability of the linkage plate in linkage between the support shaft and the positioning block.

[0026] In summary, this application includes at least one of the following beneficial technical effects: Through the overall structural coordination, the automated feeding of automotive connector terminals and bushings can be achieved, and the precision of terminal and bushing feeding can meet the high efficiency and precision requirements of modern production lines. By combining the structures of conveyor component A and conveyor component B, the bushings and terminals can be continuously transferred by alternating use of the two ends of the placement plate and the two trays, which greatly ensures the production efficiency of automotive connectors.

[0043] The following is in conjunction with the appendix Figure 1-15 This application will be described in further detail.

[0044] This application discloses a feeding device for automotive connector manufacturing. (Refer to...) Figure 1 A feeding device for automotive connector production, comprising: The support frame 1 has a support frame A2 fixedly connected to its top end, and a feeding mechanism 3 is assembled on the top end of the support frame A2. An extension frame 4 is fixedly connected to one side of the support frame 1. A bushing feeder 5 is fixedly connected to the top of the extension frame 4. A guide assembly 6 is provided between the bushing feeder 5 and the feeding mechanism 3. A conveying assembly A7 is assembled at the top of the support frame 1. The feeding mechanism 3 is used to cooperate with the guide assembly 6 to transfer the bushing to the conveying assembly A7. More specifically, the bushing feeder 5 consists of a drive unit, a screw shaft, a feed trough, an inlet, and an outlet. The drive unit uses a combination of a motor and a reducer, connected to the screw shaft via a coupling. The screw shaft is welded with helical blades of a specific pitch. Its working principle is based on the mechanical propulsion of the helical surface: when the drive unit drives the screw shaft to rotate, the helical blades, like a rotating thread, apply axial thrust to the bushing, causing the bushing to move forward along the helical direction within the feed trough. Due to the bushing's own weight and the frictional force with the feed trough wall, the bushing does not rotate synchronously with the helical blades, but rather forms a bushing flow that is conveyed axially. By adjusting the screw speed, changing the screw pitch, or the screw diameter, the feeding amount can be precisely controlled to achieve quantitative conveying. This is a mature existing technology and will not be elaborated further here.

[0045] Terminal feeding assembly 8 is mounted on the top of the support frame 1 at the end away from the conveying assembly A7. The end of the support frame 1 near the terminal feeding assembly 8 is equipped with the conveying assembly B10. The terminal feeding assembly 8 is used to transfer terminals to the conveying assembly B10. Loading component 9 is assembled between conveying component A7 and conveying component B10. Loading component 9 is used to transfer the bushing between conveying component A7 and conveying component B10.

[0046] Reference Figure 3 In this embodiment, the feeding assembly 6 includes: The upright plate 11 is fixedly connected to the top of the support frame 1 near the end of the bushing feeder 5. The top of the upright plate 11 is fixedly connected to the guide plate 12. The top of the guide plate 12 is provided with a feeding channel 13, and the feeding channel 13 is connected to the discharge end of the bushing feeder 5.

[0047] Reference Figure 1 In this embodiment, a stop block is fixedly connected to the top of the upright plate 11. By setting the stop block, the bushing at the end of the feeding channel 13 can be blocked, so that the push rod 16 can smoothly push the front bushing.

[0048] Reference Figure 4 In this embodiment, the top of the guide plate 12 is connected to a cover plate by screws. The cover plate can guide the top of the bushing without affecting the transmission of the bushing at the feeding channel 13, thereby ensuring the stability of the bushing transmission.

[0049] Feeding cylinder 14 is fixedly connected to one side of vertical plate 11. A push plate A15 is fixedly connected to the output end of feeding cylinder 14. Push rods 16 for pushing bushings are fixedly connected to both ends of push plate A15.

A transmission screw A18 is rotatably connected to the inner side of support frame A17. A transmission motor A19 is fixedly connected to one end of support frame A17, and the output end of transmission motor A19 is also fixedly connected to transmission screw A18.

[0051] Reference Figure 5 In this embodiment, a light rod A is fixedly connected to the inner side of the support frame A17, and the displacement frame A20 is also slidably connected to the light rod A. By setting the light rod A, the displacement of the displacement frame A20 can be effectively guided, preventing the displacement frame A20 from rotating with the transmission screw A18, which greatly ensures the stability of the displacement frame A20 during displacement. The displacement frame A20 is threaded to the outside of the transmission screw A18. A transmission cylinder A21 is fixedly connected to one side of the displacement frame A20. An adjustment frame A22 is fixedly connected to the output end of the transmission cylinder A21. A settling frame 23 is fixedly connected to one side of the adjustment frame A22. A pneumatic gripper A24 is fixedly connected to one side of the settling frame 23 for gripping the bushing.

[0052] Reference Figure 7 In this embodiment, the conveying component A7 includes: Positioning plate 25 is fixedly connected to the top of the support frame 1 near the vertical plate 11. The top of the positioning plate 25 is vertically rotatably connected to the central shaft 26. The top of the central shaft 26 is fixedly connected to the settling plate 27. The top of the settling plate 27 is fixedly connected to multiple feeding columns 28.

[0053] Reference Figure 7 In this embodiment, a plug is fixedly connected to the top of the feeding column 28, and a rubber ring is provided on the outside of the plug. More specifically, by setting the insert rod, when the bushing is positioned at the top of the discharge column 28, the insert rod will be moved into the through hole in the middle of the bushing to restrict the bushing and prevent the bushing from falling off the discharge column 28. Furthermore, the presence of the rubber ring can also provide a certain degree of protection for the bushing, preventing damage to the bushing caused by the insertion rod.

[0054] Reference Figure 7 In this embodiment, the diameter of the transmission spur gear 31 is smaller than the diameter of the reduction spur gear 32. By changing the diameters of the transmission spur gear 31 and the reduction spur gear 32, the rotation speed of the central shaft 26 can be effectively controlled, making the adjustment of the settling plate 27 more stable. The positioning seat 29 is fixedly connected to one side of the positioning disk 25. The top of the positioning seat 29 is fixedly connected to the drive motor 30. The output end of the drive motor 30 is fixedly connected to the transmission spur gear 31. The outer side of the central shaft 26 is fixedly connected to the reduction spur gear 32, and the reduction spur gear 32 is also meshed with the transmission spur gear 31.

[0055] Reference Figure 8 In this embodiment, the terminal feeding assembly 8 includes: Two terminal feeders 33 are fixedly connected to the top of the support frame 1, and the discharge end of each terminal feeder 33 is fixedly connected to a feeding rail 34. More specifically, the terminal feeder 33 consists of a drive unit, a screw shaft, a feed trough, an inlet, and an outlet. The drive unit uses a combination of a motor and a reducer, connected to the screw shaft via a coupling. The screw shaft has helical blades with a specific pitch welded on it. Its working principle is based on the mechanical propulsion of the helical surface: when the drive unit drives the screw shaft to rotate, the helical blades, like a rotating thread, apply axial thrust to the terminals, causing them to move forward along the helical direction within the feed trough. Due to the terminals' own weight and friction with the feed trough wall, the terminals do not rotate synchronously with the helical blades, but rather form a terminal flow that is conveyed axially. By adjusting the screw speed, changing the pitch, or the screw diameter, the feeding amount can be precisely controlled to achieve quantitative conveying. This is a mature existing technology and will not be elaborated further here.

[0056] In this embodiment, a stabilizing frame is fixedly connected to the top of the support frame 1, and the top of the stabilizing frame is also fixedly connected to the feeding rail 34. By setting the stabilizing frame, the feeding rail 34 can be auxiliaryly supported, so as to avoid the uncontrollable shaking of the feeding rail 34 when the terminal is transmitted at the feeding rail 34, which greatly ensures the application effect of the feeding rail 34.

[0057] Two support frames B35 are fixedly connected to the top of the support frame 1, and the two support frames B35 correspond to the two feeding rails 34 respectively. A support frame B36 is fixedly connected to the top of the support frame B35. A transmission screw B37 is rotatably connected to the inner side of the support frame B36. A transmission motor B39 is fixedly connected to one end of the support frame B36, and the output end of the transmission motor B39 is also fixedly connected to the transmission screw B37.

[0058] Reference Figure 9 In this embodiment, a light rod B is fixedly connected to the inner side of the support frame B36, and the displacement frame B38 is also slidably connected to the light rod B. By setting the light rod B, the displacement of the displacement frame B38 can be effectively guided, preventing the displacement frame B38 from rotating with the transmission screw B37, and greatly ensuring the stability of the displacement frame B38 during displacement.

[0059] The displacement frame B38 is threaded to the outside of the transmission screw B37. A transmission cylinder B40 is fixedly connected to one side of the displacement frame B38. An adjustment frame B41 is fixedly connected to the output end of the transmission cylinder B40. A pneumatic gripper B42 is fixedly connected to one side of the adjustment frame B41 for gripping the terminal.

[0060] Reference Figure 10 In this embodiment, the loading component 9 includes: Two columns 43 are fixedly connected to the top of the bearing frame 1. A carrier plate 44 is fixedly connected between the tops of the two columns 43. Support blocks 45 are fixedly connected to both ends of the carrier plate 44. The transmission screw C46 is rotatably connected between two support blocks 45. One side of one of the support blocks 45 is fixedly connected to a transmission motor C47, and the output end of the transmission motor C47 is also fixedly connected to the transmission screw C46. The displacement frame C48 is threaded to the outside of the transmission screw C46. A transmission cylinder C49 is fixedly connected to one side of the displacement frame C48. A guide frame 50 is fixedly connected to the output end of the transmission cylinder C49. Multiple pneumatic grippers C51 are fixedly connected to the bottom end of the guide frame 50 for gripping the bushing.

[0061] In this embodiment, pneumatic grippers A24, B42, and C51 each consist of a cylinder, a transmission mechanism, gripping fingers, and a mounting base. Their working principle is based on pneumatic transmission and mechanical force amplification: when a solenoid valve controls compressed air to enter the cylinder chamber, it pushes a piston to move the transmission mechanism, causing the gripping fingers to perform clamping or releasing actions. The clamping force can be controlled by adjusting the air source pressure. Closed-loop control of position and force can be achieved in conjunction with a magnetic switch or pressure sensor. This is a mature existing technology and will not be elaborated further here.

[0062] Reference Figure 11 In this embodiment, the conveying component B10 includes: The mounting frame 52 is fixedly connected to the top of the support frame 1. Two threaded rods 53 are rotatably connected to the inner side of the mounting frame 52. One end of each threaded rod 53 is fixedly connected to a reversing spur gear 54, and the two reversing spur gears 54 are meshed together. One end of the mounting frame 52 is fixedly connected to a motor 55, and the output end of the motor 55 is also fixedly connected to one of the threaded rods 53. Two transmission racks 56 are threadedly connected to two threaded rods 53 respectively. An adjusting cylinder 57 is fixedly connected to one side of the transmission rack 56. A support plate 58 is fixedly connected to the output end of the adjusting cylinder 57. A positioning hole 59 is opened in the middle of the top of the support plate 58. Multiple placement columns 60 are fixedly connected to the middle of the top of the support plate 58 for placing bushings.

[0063] Reference Figure 11 In this embodiment, a limiting slide rail is fixedly connected to one side of the transmission frame 56, and a limiting slider is fixedly connected to the tray 58, and the limiting slider is also slidably connected to the limiting slide rail. More specifically, the structure of the limiting slide rail and the limiting slider can guide the vertical adjustment of the tray 58, greatly ensuring the stability of the tray 58 during adjustment.

[0064] Reference Figure 11 In this embodiment, a limiting groove is provided at the bottom of the inner side of the mounting frame 52, and the bottom of the transmission frame 56 is also slidably connected to the inside of the limiting groove. More specifically, a linear slider is fixedly connected to the bottom of the transmission frame 56. The transmission frame 56 is connected to the inside of the limiting slide groove through the linear slider. Through the structural cooperation of the linear slider and the limiting slide groove, the displacement of the transmission frame 56 can be effectively guided, preventing the transmission frame 56 from rotating with the threaded rod 53 and ensuring the stability of the transmission frame 56 during adjustment.

[0065] Furthermore, the cross-sectional shape of both the limiting groove and the linear slider can be T-shaped. Through the geometric design of the T-shaped cross-section of the limiting groove and the linear slider, the linear slider forms a bidirectional constraint within the limiting groove, effectively resisting lateral offset and overturning moment, with strong load-bearing capacity and smooth movement, effectively ensuring the connection effect between the limiting groove and the linear slider.

[0066] Four bases 61 are fixedly connected to the four corners of the top of the support plate 58, and a positioning block 62 is slidably connected to the middle of each base 61.

Push frame 65 is fixedly connected to the output end of electric push rod 64. Support shaft rod 66 is fixedly connected to both ends of push frame 65. Linkage plate 67 is rotatably connected to both ends of each support shaft rod 66. The ends of the four linkage plates 67 away from the support shaft rod 66 are rotatably connected to four positioning blocks 62 respectively.

[0067] Reference Figure 15 In this embodiment, one end of the positioning block 62 is provided with a mounting hole, and the end of the linkage plate 67 away from the support shaft 66 is connected to the inside of the mounting hole through a rotating shaft. More specifically, the mounting holes allow the linkage plate 67 to be stably assembled with the positioning block 62 via the rotating shaft, ensuring the stability of the linkage plate 67 in linkage between the support shaft 66 and the positioning block 62. Reference Figure 15In this embodiment, a stabilizing slide rod is vertically slidably connected to the bottom end of the support base 63, and the bottom end of the stabilizing slide rod is also fixedly connected to the pusher frame 65. By setting the stabilizing slide rod, the vertical stroke of the pusher frame 65 can be guided to avoid uncontrollable displacement of the pusher frame 65.

[0068] The implementation principle of the automotive connector production feeding device in this application embodiment is as follows: start the bushing feeder 5 to feed the bushings sequentially to the feeding channel 13 and adjust the bushings along the feeding channel 13. When the foremost bushing reaches above the push rod 16, start the feeding cylinder 14 to push the push plate A15 upward and adjust it so that the push rod 16 is close to the foremost bushing. As the push rod 16 contacts the bushing, it can lift the foremost bushing. Simultaneously, the drive motor A19 is activated to drive the drive screw A18 to rotate. This, combined with the connection between the drive screw A18 and the displacement frame A20, allows the displacement frame A20 to adjust along the drive screw A18 until the pneumatic gripper A24 reaches above the bushing at the push rod 16. Then, the drive cylinder A21 is activated to push the positioning frame 23 downwards, and the pneumatic gripper A24 removes the bushing from the push rod 16. Finally, the drive motor A19 is activated again, and, in conjunction with the connection between the drive screw A18 and the displacement frame A20, the bushing is adjusted... The bushings are temporarily supported on the feeding column 28 at one end of the placement plate 27. After the bushings are placed on the feeding column 28 at one end of the placement plate 27, the drive motor 30 is started to drive the transmission spur gear 31 to rotate, which causes the transmission spur gear 31 to move the reduction spur gear 32, and then drives the placement plate 27 to rotate 180 degrees through the central shaft 26, so that the end of the placement plate 27 with bushings faces the guide frame 50, and the end without bushings reaches the pneumatic gripper A24, waiting to place the bushings. The terminal feeder 33 is started to transfer terminals to the feed rail 34, and the drive motor B39 is started to drive the drive screw B37 to rotate. With the connection between the drive screw B37 and the displacement frame B38, the displacement frame B38 can be adjusted along the drive screw B37, thereby changing the position of the pneumatic gripper B42. When the pneumatic gripper B42 reaches the top of the terminal at the front of the feed rail 34, the drive cylinder B40 is started to push the adjustment frame B41 downward and the pneumatic gripper B42 grabs the terminal. Then, with the help of the displacement frame B38 adjusting along the drive screw B37, the terminal is transferred to the base 61 on one of the trays 58. After there are terminals at each base 61, the electric push rod 64 is started to pull the pusher 65 upward. Since the linkage plate 67 is connected between the support shaft 66 and the positioning block 62, when the position of the pusher 65 changes, the linkage plate 67 will push the positioning block 62, thereby cooperating with the base 61 to achieve the positioning of the terminal. Then, the adjusting cylinder 57 at one of the pallets 58 is activated, causing the pallet 58 to be adjusted downward, so that there is a height difference between the two pallets 58. Then, the motor 55 is started to drive the threaded rod 53 connected to it to rotate. With the setting of two reversing spur gears 54, the power of the motor 55 can be transmitted to the other threaded rod 53, causing the two threaded rods 53 to rotate simultaneously in opposite directions. As a result, one pallet 58 moves away from the reversing spur gear 54, while the other pallet 58 is adjusted towards the pneumatic gripper B42. When one pallet 58 reaches below the pneumatic gripper C51, the other pallet 58 will simultaneously reach the pneumatic gripper B42. Then, the terminals are loaded onto the other pallet 58 through the pneumatic gripper B42. Finally, the drive motor C47 is started to drive the drive screw C46 to rotate. In conjunction with the connection between the drive screw C46 and the displacement frame C48, the displacement frame C48 can be adjusted along the drive screw C46, ​​thereby changing the position of the pneumatic gripper C51. When the pneumatic gripper C51 reaches above the bushing on the placement plate 27, the drive cylinder C49 is started to push the guide frame 50 downward and the pneumatic gripper C51 grabs the bushing on the placement plate 27. After grabbing, the drive motor C47 is started to cause the displacement frame C48 to adjust towards the support plate 58. When the position of the bushing corresponds to the position of the placement column 60, the pneumatic gripper C51 is moved down to place the bushing on the placement column 60, thereby realizing the loading of terminals and bushings.

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.
