Description

Technical Field

[0001] This invention relates to the cutting and assembly of connecting terminals, and in particular to a connecting terminal cutting and assembly apparatus. Background Technology

[0002] Connectors typically consist of several component assemblies, with the core component being the connecting terminals. During the production process, the connecting terminals are usually produced by conveying a strip of material, which is then stamped several times on the strip and then cut. The connecting terminals and the strip are then analyzed to obtain individual connecting terminals.

[0003] Because connecting terminals are usually not regular parts, such as the spring clips of connecting terminals which are bending mechanisms, conventional cutting devices have difficulty achieving continuous feeding of connecting terminals. Moreover, in order to improve production efficiency, it is necessary to continuously cut connecting terminals, and then grip and place the connecting terminals in a fixture for assembly. However, current cutting devices have the following problems after cutting:

[0004] 1. After cutting, the material cannot be directly taken out and needs to be manually arranged and packaged again, resulting in low production efficiency;

[0005] 2. The connector terminals are high-precision products. Free fall can cause deformation and uncontrollable condition of the connector terminals. Manual arrangement can also cause secondary contamination of the product, affecting its transmission performance.

[0006] 3. The structure of the connecting terminal is not on the same horizontal dimension as the material strip, which makes continuous feeding of the material strip inconvenient.

[0007] The small size of the connector makes gripping difficult. Furthermore, the central part of the connector is a plastic-encapsulated component with low structural strength, requiring very high clamping force. During gripping, the robot cannot contact the conductive parts on the connector. Most importantly, the small size of the connector and the small gripping holes on the cutting die result in a narrow gripping end for the robot. The robot must also penetrate deep into the die's concave cavity to grip the connector, further reducing the length of the gripping end. Additionally, the robot requires extremely high positioning accuracy during gripping. Therefore, current robots struggle to meet the required gripping accuracy for larger aspect ratios.

[0022] The present invention has the following advantages:

[0023] 1. The cutting module of the present invention can first press the connecting terminal with the cam pressure block during die closing and cutting, and then complete the cutting, thereby ensuring the cutting quality of the connecting terminal. Moreover, through the lifting component and the lifting component, during feeding, the lower module can first be lowered to provide space for the material strip to feed, and then the lower module is reset to realize the cooperation between the connecting terminal and the lower mold core. Then the lifting component makes the upper module lowered, thereby realizing the die closing of the upper and lower modules. Therefore, the connecting terminal cutting device can realize continuous feeding and improve disassembly efficiency.

[0024] 2. In the clamping module of this invention, the movement of the clamp is constrained by the dovetail groove and dovetail block, as well as the limiting cavity. Therefore, the movement of the clamp has dual constraints, which improves the linear accuracy of the clamp movement and thus significantly improves the clamping accuracy. As a result, the clamp can be longer and smaller, with a high aspect ratio, and can be used in environments with limited space and smaller products. This improves the reliability and practicality of the robotic arm in gripping the connecting terminals, and solves the technical problem that lengthening the traditional clamp will lead to amplified errors and unstable clamping.

[0025] 3. The assembly module of the present invention can quickly realize the positioning of the connection terminal, and can also avoid the deformation of the connection terminal during the pressing process of the connection terminal, thereby ensuring the reliability of the connection between the connection terminal and the cable.

Detailed Implementation

[0063] like Figure 1 and Figure 2 As shown, a connector terminal cutting and assembly device includes a workbench with a cutting module 140, a clamping module 150 and an assembly module 160 mounted on it. The cutting module 140 disassembles the connector terminal, the clamping module 150 picks up the cut connector terminal and places it on the assembly module 160, and the assembly module 160 connects the connector terminal to the cable, thereby realizing the cutting and assembly of the connector terminal.

[0064] In this embodiment, as Figures 3-18As shown, the cutting module 140 includes an upper module 100, a lower module 200, a lifting assembly 400 for driving the upper module 100 downward, and a lifting assembly 300 for driving the lower module 200 upward. An upper mold core 10 is mounted on the lower surface of the upper module 100, and an upper mold core 10 is mounted on the upper surface of the lower module 200. The upper mold core 10 and lower mold core 20 are the mold cores of the cutting module 140. A guide rod 30 is also installed between the upper mold core 10 and the lower mold core 20. A through-hole material-taking groove 16 is opened on the upper mold core 10. An upper cutter 14 is mounted on the upper mold core 10, located to the left of the material-taking groove 16. A clearance groove 15 is opened on the upper mold core 10, located to the right of the material-taking groove 16, and the clearance groove 15 is perpendicular to the material-taking groove 16. The material groove 16 is connected, and a rotatable cam pressing block 13 is installed in the clearance groove 15. The cam pressing block 13 includes a lever 131. The head of the lever 131 is provided with a pressing head 133 made of soft material. A rotating shaft 135 is provided at the bottom corner of the lever 131. The two ends of the rotating shaft 135 are rotatably mounted on the upper mold core 10. An inwardly recessed groove 136 is also provided on the inner side of the lever 131. The rotating shaft 135 passes through the groove 136. A torsion spring 134 is also installed on the rotating shaft 135 located in the groove 136. One torsion arm of the torsion spring 134 abuts against the bottom of the groove 136, and the other torsion arm of the torsion spring 134 abuts against the side wall of the clearance groove 15. A rotatable roller 132 is installed at the tail of the lever 131.The lower mold core 20 is equipped with a lower cutter 24 that cooperates with the upper cutter 14 for cutting. The lower mold core 20 also has a cam pusher 23 that rotates the cam pressure block 13. The cam pusher 23 is located on one side of the lower cutter 24. The upper mold core 10 has an insertion hole for the cam pusher 23 to insert into the clearance groove 15. When the upper mold core 10 and lower mold core 20 are closed, the cam pusher 23 is inserted from the insertion hole into the clearance groove 15. When the cam pusher 23 contacts the roller 132, the cam pusher 23 applies a pushing force to the roller 132. The force causes lever 131 to rotate around shaft 135, thereby causing pressure head 133 to press against the middle of the connecting terminal. While lever 131 rotates, torsion spring 134 generates torque. When upper mold core 10 and lower mold core 20 are demolded, lever 131 returns to its original position under the action of torsion spring 134. In this embodiment, a stop surface is provided on the clearance groove 15. When lever 131 contacts the stop surface under the torque of torsion spring 134, lever 131 is completely located within the clearance groove 15. During the mold closing process, when... After the pressure head 133 contacts the center of the connecting terminal, it presses down on the terminal. Then, as the upper mold core 10 and lower mold core 20 close, the pressure head 133 deforms. Preferably, the pressure head 133 is made of rubber or silicone. Through the deformation and compression of the pressure head 133, it ensures that the pressure head 133 can continuously apply pressure to the connecting terminal, guaranteeing the clamping force of the connecting terminal. Then, when the upper cutter 14 and lower cutter 24 move relative to each other, the connecting terminal is separated from the strip, achieving cutting. Because the connecting terminal is pressed down during the cutting process, it will not vibrate, thus ensuring the cutting quality of the connecting terminal. Furthermore, during demolding, because the pressure head 133 is made of a soft material, the pressure on the connecting terminal gradually decreases, preventing the connecting terminal from suddenly losing pressure and thus preventing vibration and collisions. This ensures the fixed position of the connecting terminal, facilitating its gripping.

[0065] In this embodiment, after the pressure head 133 contacts the middle of the connector, the upper module 100 continues to descend as the mold closing proceeds. Preferably, before the mold closing, the roller 132 rolls from the top of the cam push rod 23 to the side wall of the cam push rod 23. At this time, although the upper module 100 descends, the roller 132 has already rolled to the side wall of the cam push rod 23, and the pressing force of the pressure head 133 on the connecting terminal remains constant, thereby preventing the pressure head 133 from damaging the connecting terminal and also preventing the pressure head 133 from deforming too much and causing damage, thus ensuring the service life of the pressure head 133.

[0066] In this embodiment, the upper mold core 10 includes a first plate 11 and a second plate 12 that are detachably connected. Preferably, the first plate 11 and the second plate 12 are detachably connected by locking screws. The upper cutter 14 is installed between the first plate 11 and the second plate 12, and the cutting edge of the upper cutter 14 protrudes from the lower surface of the second plate 12. Furthermore, a limiting block 141 is provided at the top of the upper cutter 14, and protruding ribs 142 are provided on both sides of the upper cutter 14. A notch matching the upper cutter 14 and a limiting groove 1112 matching the protruding ribs 142 are provided on the second plate 12. A groove corresponding to the limiting block 141 is provided at the bottom of the first plate 11. When the first plate 11 and the second plate 12 are installed, the limiting block 141 is locked in the groove, and the protruding ribs 142 are locked in the limiting groove 1112, thereby preventing relative displacement between the upper cutter 14 and the upper mold core 10.

[0067] In this embodiment, grooves are provided at the contact surfaces of the first plate 11 and the second plate 12, and the two grooves form a clearance groove 15. The second plate 12 is provided with an insertion hole for easy insertion of the cam push rod 23. Furthermore, the groove on the second plate 12 is a through groove that runs vertically through the groove. The bottom of the groove is covered by a cover plate 19, and an insertion hole is provided on the cover plate 19. The cover plate 19 and the second plate 12 are locked together by a locking screw. When the cover plate 19 is installed, the cover plate 19 does not protrude from the lower surface of the second plate 12, and the corresponding torsion arm on the torsion spring 134 abuts against the cover plate 19.

[0068] In this embodiment, the lower mold core 20 includes a detachable third plate 21 and a fourth plate 22. The third plate 21 and the fourth plate 22 are also detachably connected by locking screws. The bottom of the lower cutter 24 and the cam ejector 23 are installed between the third plate 21 and the fourth plate 22. A blanking groove 25 is provided on the third plate 21. The blanking groove 25 extends downward and penetrates the fourth plate 22. The protruding part of the upper cutter 14 can be inserted into the blanking groove 25. Therefore, when the mold is closed, the upper cutter 14 enters the blanking groove 25, and the cut end of the connecting terminal is received by the lower cutter 24, thereby preventing the cut end of the connecting terminal from deforming.

[0069] In this embodiment, a notch is formed on the third plate 21 near the material feeding groove 25. Slots 215 are formed on both sides of the notch. The lower cutter 24 is installed in the notch. The lower cutter 24 has locking blocks 241 on both sides that cooperate with the slots 215. A storage groove 243 is formed on the upper surface of the lower cutter 24 away from the cutting edge. A receiving groove 212 is formed on the upper surface of the third plate 21. The receiving groove 212 is connected to the storage groove 243. The side wall of the receiving groove 212 near the storage groove 243 is a slope surface 213. Several partition blocks 214 are formed on the slope surface 213, thereby forming several dividing grooves on the slope surface 213. The bottom of the lower cutter 24 The part is provided with a flange 242, which is pressed between the third plate 21 and the fourth plate 22. In this embodiment, a strip has several parallel connecting terminals. Before cutting, the middle part of the connecting terminal is located in the storage groove 243, and the shape of the storage groove 243 is set according to the shape and size of the middle part of the connecting terminal. The end of the spring of the connecting terminal is located in the receiving groove 212, and two adjacent connecting terminals are separated by a partition block 214, thereby avoiding collision between the connecting terminals. Moreover, during feeding, the relative position between the two connecting terminals can be guaranteed, so that the spring of the connecting terminal can enter the corresponding partition groove independently.

[0070] In this embodiment, at least two sets of spaced elastic pillars 18 are also installed on the upper mold core 10, with at least one set of elastic pillars 18 located on the front side of the upper cutter 14 and at least one set of elastic pillars 18 located on the rear side of the material take-up groove 16. Each elastic pillar 18 includes a stepped pillar, a compression spring, and a plug 1115. A stepped hole is provided on the second plate 12, and the stepped pillar is fitted into the stepped hole. A corresponding through hole is provided on the first plate 11, and a plug 1115 is installed in the through hole. Preferably, the plug 1115 and the through hole are threadedly connected, and the compression spring is compressed between the stepped pillar and the plug 1115. When the mold is closed, the elastic pillars 18 press down on the strip, preventing the strip from moving and thus ensuring the connection of the terminal on the strip. Preferably, each set of elastic pillars 18 has two, so that when the mold is closed, all four corners of the strip can be pressed down, thus preventing the strip from moving and ensuring the cutting quality of the connection terminal.

[0071] In this embodiment, because the connecting terminal and the material strip are not on the same horizontal dimension, it is difficult to feed the connecting terminal during the horizontal movement of the material strip. Furthermore, as... Figure 17As shown, the lifting assembly 300 includes a base 500 and a translation cylinder 301. The translation cylinder 301 is mounted on the base 500. A pair of guide grooves 304 are provided on the top of the base 500, extending in the left-right direction. A sliding rail 303 is slidably fitted within the guide groove 304. One end of the sliding rail 303 is connected to a moving plate 302. The telescopic shaft of the translation cylinder 301 is connected to the moving plate 302. An inclined surface 305 is provided on the sliding rail 303. Side plates 202 are installed on the front and rear side walls of the lower mold core 20, and rolling elements 203 are installed on the side plates 202. When the sliding rail 303 moves left and right, the rolling elements 203 roll along the surface of the sliding rail 303. Because the sliding rail 303 has an inclined surface 305, it has an upper rail surface and a lower rail surface. When the rolling element 203 moves from the lower rail surface to the upper rail surface, the lower die 200 rises, and when the rolling element 203 moves from the upper rail surface to the lower rail surface, the lower die 200 descends. Therefore, during feeding, the rolling element 203 is located on the lower rail surface, and the lower die 200 is in the lower stroke, which makes the lower die core 20 move away from the material strip, thus making room for the forward and backward movement of the connecting terminal. When the material strip drives the connecting terminal into the cutting station, the translation cylinder 301 works again, causing the rolling element 203 to move from the lower rail surface to the upper rail surface. At this time, the lower die 200 moves upward, which causes the middle part of the connecting terminal to enter the placement groove 243, while the spring of the connecting terminal is located in the partition groove, thus realizing the continuous feeding of the connecting terminal driven by the material strip and ensuring the cutting efficiency of the connecting terminal.

[0072] In this embodiment, as Figure 18As shown, the lifting assembly 400 includes a base plate 1203, on which a lifting cylinder 401 and a rotating support 403 are mounted. The rotating support 403 is located on one side of the lifting cylinder 401, and a rotating plate 402 is rotatably mounted on the rotating support 403. One end of the rotating plate 402 is located above the telescopic shaft of the lifting cylinder 401, and the lifting cylinder 401 lifts the rotating plate 402, causing it to rotate around the rotating support 403. A pair of cantilever arms 403 are provided at the other end of the rotating plate 402. A rotatable pressure roller 405 is provided on the inner side of each cantilever arm 403. At least two pull rods 104 are provided on the upper module 100, and the lower ends of the pull rods 104 pass through the lower module 200 and... Connected to a pull-down plate 406, the pull-down plate 406 has a pull-down groove 407 corresponding to the pressure roller 405. The pressure roller 405 rolls in the pull-down groove 407. When the piston rod of the lifting assembly 400 extends, the rotating plate 402 rotates around the rotating support 403, while the other end of the rotating plate 402 swings downward. During the downward swing of the pressure roller 405, it rolls along the pull-down groove 407 and applies a downward pulling force to the pull-down plate 406, thereby causing the pull-down plate 406 to move downward. After the pull-down plate 406 moves downward, it drives the upper module 100 to move downward through the pull-down rod 104, thereby realizing the mold closing of the upper module 100 and the lower module 200 and completing the cutting of the connecting terminal.

[0073] In this embodiment, the upper module 100 further includes an upper template 101, with the upper mold core 10 mounted on the lower surface of the upper template 101. The lower module 200 further includes a lower template 201, with the lower mold core 20 mounted on the upper surface of the lower template 201. The top of the pull rod 104 is mounted on the upper template 101, and the bottom of the pull rod 104 passes through the lower template 201 and connects to the pull plate 406. At least two guide posts 103 are also provided on the upper template 101, with the bottom of the guide posts 103 passing through the lower template 201. A return spring 102 is also fitted on the guide post 103 located between the upper template 101 and the lower template 201. During the downward movement of the upper template 101, the return spring 102 is compressed. When the lifting cylinder 401 is reset, the upper module 100 is then compressed by the return spring. Under the action of 102, it moves upward, thereby realizing the demolding of the upper module 100 and the lower module 200. Moreover, after the reset spring 102 is installed, the reset spring 102 is in a compressed state. When the upper module 100 is stationary, when the rolling element 203 moves from the upper rail surface to the lower rail surface, the reset spring 102 will also apply downward pressure to the lower module 200, causing the lower module 200 to move downward, thus ensuring the reliability of the lower module 200's downward movement. In the initial state, although the reset spring 102 can also apply an upward thrust to the upper module 100, this thrust is transmitted to the pressure roller 405 through the pull groove 407 on the pull plate 406, causing one end of the rotating plate 402 to abut against the telescopic shaft of the lifting cylinder 401, thereby preventing the upper module 100 from moving upward in the initial state.

[0074] In this embodiment, a pre-positioning groove 211 is also provided on the upper surface of the third plate 21. The pre-positioning groove 211 is a stepped groove and is located at the front end of the receiving groove 212. When the upper section of the strip is cut, the connecting terminal of the lower section of the strip is located in the pre-positioning groove 211. In this way, the blank area between the two sections of the strip can be shortened, thereby saving raw materials.

[0075] In this embodiment, a positioning post 17 is also installed on the upper mold core 10. The positioning post 17 is located on the front side of the elastic column 18. The lower mold core 20 is provided with a positioning hole 216 corresponding to the positioning post 17. Through the positioning post 17 and the positioning hole 216, the accuracy of the mold closing of the upper mold core 10 and the lower mold core 20 can be further ensured, thereby ensuring the quality of the connecting terminal cutting.

[0076] In this embodiment, one end of the material strip is a feeding mechanism 130, and the other end of the material strip is a traction mechanism. The feeding mechanism 130 delivers the connecting terminals on the material strip to the cutting module 140, while the traction mechanism pulls the cut material strip out of the cutting module 140. In this embodiment, both the feeding mechanism 130 and the traction mechanism are existing technologies, so they will not be described in detail.

[0077] When the cutting module 140 cuts the connecting terminals, the strip moves backward under the action of the feeding mechanism 130 and the traction mechanism. When the lower module 200 needs to be fed, the translation cylinder 301 works, causing the rolling element 203 to move from the upper rail surface to the lower rail surface. As the rolling element 203 rolls down the ramp 305, the lower module 200 moves downward, which in turn drives the lower die core 20 downward, thereby causing the strip to separate from the lower die core 20, thus making room for the feeding of the connecting terminals. Then the traction mechanism works, causing the connecting terminals on the strip to enter the cutting station, and then the translation cylinder 301 moves downward. Cylinder 301 resets, rolling element 203 rolls from the lower rail surface to the upper rail surface, lower module 200 moves upward, causing the connecting terminal to enter the corresponding receiving groove 212 and storage groove 243. Then, lifting cylinder 401 moves upward, rotating plate 402 rotates, causing lower pressure roller 405 to exert a downward pulling force on lower pressure plate, lower pressure plate moves downward, causing return spring 102 to be further compressed. During the downward movement of lower pressure plate, upper module 100 also moves downward, causing upper module 100 and lower module 200 to close. During mold closing, cam ejector rod 23 first inserts into the insertion hole and then contacts roller 132. This causes lever 131 to rotate, which in turn causes pressure head 133 to gradually approach the center of the connecting terminal. Once pressure head 133 contacts the center of the connecting terminal, as the mold closes, pressure head 133 continuously applies pressure to the center of the connecting terminal, ensuring the clamping force of the connecting terminal and preventing it from moving during cutting, thus ensuring cutting quality. After mold closing, the connecting terminal is cut from the material strip through the cooperation of upper cutter 14 and lower cutter 24. Then, lifting cylinder 401 resets. During the reset process, the upper mold assembly 100 is held in place by the elasticity of the reset spring 102. Under the action of restoring force, the upper module 100 moves upward, which in turn drives the lower pull plate 406 to move upward, thereby causing the rotating plate 402 to rotate in the opposite direction. When the other end of the rotating plate 402 abuts against the telescopic rod of the lifting cylinder 401, the upper module 100 stops moving upward. At this time, the upper module 100 returns to the initial state, and the upper module 100 and the lower module 200 are demolded. At this time, the connecting terminal is located on the lower mold core 20. Then, by inserting the clamping module 150 from the material picking groove 16 to clamp the connecting terminal, the connecting terminal can be taken out from the material picking groove 16, and then the next cutting can be performed.

[0078] In this embodiment, the clamping module 150 includes a rotating mechanism and a linear motion module 510. The rotating mechanism is mounted on the worktable. Since the rotating mechanism is prior art, it will not be described in detail. The linear motion module 510 is mounted on the rotating mechanism. Furthermore, a sliding plate 520 is provided on the linear motion module, and a robot arm 530 is mounted on the sliding plate 520. Since the linear motion module 510 is prior art, it will not be described in detail. In this embodiment, the linear motion module 510 drives the sliding plate 520 to move up and down. That is to say, the robot arm 530 moves up and down with the sliding plate 520. When the sliding plate 520 moves to the lower stroke, the robot arm 530 works to clamp the connector. Then the sliding plate 520 moves to the upper stroke to remove the connector vertically upward from the cavity.

[0079] In this embodiment, as Figures 19-23As shown, the robotic arm 530 includes a gripper cylinder 51, with a gripper 53 connected to the actuating end of the gripper cylinder 51. In this embodiment, the gripper cylinder 51 is a double-headed gripper. When the gripper cylinder 51 operates, the two grippers 53 move towards or away from each other, thereby achieving the gripping and releasing of the connector. Furthermore, a pair of limiting members 52 are installed on the outer wall of the gripper cylinder 51. The two limiting members 52 are arranged opposite to each other, and two protruding guard plates and protruding posts 522 are provided on the opposite surfaces of the limiting members 52. The protruding posts 522 are located between the two guard plates, and the two limiting members 52 form a cavity. The cavity is divided into two limiting cavities 521 by the two protruding posts 522. The grippers 53 are slidably installed in the corresponding limiting cavities 521, and the grippers 53 can slide left and right relative to the limiting members 52. The protective plate is also equipped with a limiting screw 524. The clamping end of the clip 53 is located below the limiting cavity 521. The bottom of the clamping end of one of the clips 53 is provided with several spaced positioning teeth 531. Adjusting the limiting screw 524 can change the stroke of the clip 53 in the limiting cavity 521, thereby adjusting the farthest distance between the two clips 53. In this embodiment, when the two clips 53 are at their shortest distance, they just clamp the connector. The width of the protrusion 522 determines the shortest distance between the two clips 53. That is to say, during the design, the width of the protrusion 522 can be reasonably designed according to the model of the connecting terminal to ensure the stability of the clamping force of the clip 53 on the connecting terminal, thereby ensuring the reliability of the connecting terminal clamping. Furthermore, the limiting cavity 521 restricts the movement of the clamp 53. That is, the front and rear sidewalls of the clamp 53 are in a sliding fit with the sidewalls of the corresponding limiting member 52, thus ensuring the linear accuracy of the clamp 53's movement in the left and right directions. Further, the gripper cylinder 51 has a dovetail groove 54, within which dovetail blocks 55 are installed in pairs, and the dovetail blocks 55 are in a sliding fit with the dovetail groove 54. The gripper cylinder 51 drives the dovetail blocks 55 to slide within the dovetail groove 54, and the top of the clamp 53 connects to the dovetail blocks 55. Therefore, the movement of the clamp 53 in the left and right directions is constrained by the dovetail groove 54, the dovetail blocks 55, and the limiting cavity 521, resulting in high linear movement accuracy of the clamp 53. In this embodiment, the robotic arm... 530 needs to extend into the concave mold of the cutting die to clamp the connecting terminal. Therefore, the size of the clamp 53 needs to be longer and smaller, that is, the length-to-width ratio of the clamp 53 needs to be large, at least more than 1.5 times. With such a large length-to-width ratio, if the straightness of the top of the clamp 53 cannot be guaranteed when it moves left and right, the clamping accuracy of its clamping end will be further amplified, resulting in the inability to guarantee the accuracy of the clamping end of the clamp 53, and thus making it impossible to reliably clamp the connecting terminal. In this embodiment, the top of the clamp 53 is constrained by the dovetail groove 54 and the dovetail block 55 as well as the limiting cavity 521, and can be longer and smaller than the traditional clamp 53, that is, the length-to-width ratio can reach more than 1.5 times. Therefore, it can be used in confined spaces and smaller product usage environments.This allows the connecting terminals inside the die cavity of the cutting mold to be gripped.

[0080] In this embodiment, a connecting arm 532 is provided on the top of the clip 53, and a mounting groove 533 is provided on the connecting arm 532. A connecting block 56 is provided on the dovetail block 55. The connecting block 56 can be detachably installed in the mounting groove 533, which facilitates the replacement of the clip 53 and makes it suitable for more types of connecting terminals. Furthermore, some of the connecting blocks 56 are located outside the mounting groove 533, and a gasket is installed between the connecting block 56 and the mounting groove 533. In this embodiment, depending on the different connecting terminals, the farthest distance of the clip 53 in the limiting cavity 521 can be changed by adding or removing gaskets and adjusting the limiting screw 524.

[0081] In this embodiment, a threaded through hole is provided in the protrusion 522, and the two limiting members 52 are locked by a locking screw installed in the threaded through hole. The locking screw ensures the stability of the limiting cavity 521 structure, thereby ensuring the limiting cavity 521 limits the clamp 53. Furthermore, the threaded through hole of one of the protrusions 522 is a stepped hole, and the head of the locking screw is located in the large hole of the stepped hole, which makes the structure of the entire limiting member 52 simpler and occupies less space.

[0082] In this embodiment, the clip 53 located below the limiting cavity 521 has a thick-walled section 534, a shortened section 535, and a thin-walled section 536 connected sequentially from top to bottom. The thick-walled section 534 and the shortened section 535 have the same thickness, and the width of the shortened section 535 is smaller than the width of the thick-walled section 534. The thickness of the thin-walled section 536 is smaller than the thickness of the shortened section 535. The thick-walled section 534 can ensure the structural strength of the clip 53, while the shortened section 535 can make the clip 53 more elongated, making it easier to insert. Inside the deep hole, the thin-walled section 536 is suitable for small and deep holes. Furthermore, the outer side of the shortened section 535 of one clamp 53 is a wedge-shaped surface 1223. The wedge-shaped surface 1223 facilitates the insertion of the clamp 53 into the deep hole, and the thickness of the wedge-shaped surface 1223 decreases sequentially from top to bottom, ensuring that the clamp 53 can be inserted into the deep hole while also increasing the structural strength of the clamp 53. The positioning teeth 531 are installed at the bottom of the shortened section 535 of the other clamp 53. In this embodiment, as... Figure 35 and Figure 36As shown, the middle part of the connecting terminal is a plastic encapsulation, and the plastic encapsulations are connected in a row. There is a positioning groove 1206 between two adjacent plastic encapsulations, and the positioning teeth 531 are locked in the positioning groove 1206. When gripping, the robot arm 530 moves downward, and the positioning teeth 531 are locked in the positioning groove 1206. Then the gripper cylinder 51 works, so that the two grippers 53 move closer to each other, thereby clamping the plastic encapsulation. Then the robot arm 530 moves upward to grip the connecting terminal. Then the rotating mechanism rotates, thereby rotating the connecting terminal above the assembly module 160. Finally, the robot arm 530 moves downward to place the connecting terminal on the assembly module 160.

[0083] As a crucial component of the connector, the connecting terminal is relatively small in size. Furthermore, the central portion of the connecting terminal consists of parallel plastic-encapsulated parts, which have relatively low structural strength and are prone to deformation, such as bending, during installation. Deformed connecting terminals will affect their splicing performance with the cable. Therefore, the requirements for the assembly module are relatively high. In this embodiment, for example... Figures 25-34 As shown, the assembly module 160 includes a panel 1300, on which a wire pressing mechanism 1100 and a pushing mechanism 1200 are mounted. The wire pressing mechanism 1100 and the pushing mechanism 1200 are arranged opposite to each other. The wire pressing mechanism 1100 presses the cable, and the pushing mechanism 1200 presses the connecting terminal, so that the welding end of the connecting terminal and the welding end of the cable overlap. After the welding end of the connecting terminal and the welding end of the cable overlap, the entire fixture is moved to the next station.

[0084] In this embodiment, as Figure 26 and Figure 27 As shown, the pushing mechanism 1200 includes a base plate 1203, which is mounted on the panel 1300. A positioning groove 1206 is formed on one end of the base plate 1203 near the wire pressing mechanism 1100. A positioning member 1210 for pre-positioning the connecting terminal is provided in the positioning groove 1206. A groove is formed on one side of the positioning member 1210. In this embodiment, as shown... Figure 35 and Figure 36 As shown, the middle part of the connecting terminal is a square block, and a column is provided at the bottom of the square block. An opening groove matching the positioning member 1210 is opened on the bottom side wall of the square block. The robot arm 530 clamps the connecting terminal and places it in the positioning groove 1206. At this time, the column enters the groove to achieve one positioning. Then, as the connecting terminal is lowered, the positioning member 1210 partially enters the opening groove, thereby positioning the connecting terminal in the left and right directions. However, at this time, the connecting terminal can still move forward.

[0085] In this embodiment, a sliding groove is provided on the bottom plate 1203 located behind the positioning groove 1206. A pusher lock 1205 is slidably installed in the sliding groove. The pusher lock 1205 can slide back and forth relative to the sliding groove. A rotatable inner cover plate 1201 and an outer cover plate 1202 are installed at the rear end of the bottom plate 1203. Rotating the inner cover plate 1201 can cover the middle part of the connecting terminal. After the connecting terminal is placed in the positioning groove 1206, the connecting terminal is positioned in the left and right direction. By closing the inner cover plate 1201, the middle part of the connecting terminal covered by the inner cover plate 1201 can be pre-pressed in the up and down direction, thereby realizing the pre-positioning of the connecting terminal in the up and down direction.

[0086] In this embodiment, the pusher locking component 1205 includes a pusher plate 1221, which is slidably installed in a sliding groove. The front end of the pusher plate 1221 is provided with an upwardly protruding locking tooth 1224, the top of the locking tooth 1224 is provided with a forward-extending tooth head 1225, and the lower surface of the tooth head 1225 forms a limiting step 1226. The rear sidewall of the pusher plate 1221 is a wedge-shaped surface 1223, and the rear end of the outer cover plate 1202 is provided with... There is a pressing member 1204. Rotating the outer cover plate 1202 causes it to cover the inner cover plate 1201. During the rotation of the outer cover plate 1202, the pressing member 1204 presses against the wedge-shaped surface 1223, causing the pusher plate 1221 to move forward. In this embodiment, a stepped groove is formed between two adjacent middle parts of the connecting terminal, and the top of this stepped groove forms a positioning groove 1206. When the outer cover plate 1202 is closed, the pressing member... 1204 pushes the pusher plate 1221 forward, and the tooth 1225 is inserted into the gap between the two adjacent middle parts of the connecting terminal, that is, the tooth 1225 is stuck in the stepped groove, and the limiting step 1226 abuts against the upper surface of the stepped groove. During the forward movement of the pusher plate 1221, the pusher plate 1221 pushes the middle part of the connecting terminal forward a certain distance, so that the rear side wall of the positioning member 1210 abuts against the opening groove. When the outer cover plate 1202 is closed, the connecting terminal is fixed in all positions, thus preventing the connecting terminal from moving relative to the fixture and also preventing the connecting terminal from deforming. Even if the connecting terminal is deformed, it will be reset by the downward pressure of the outer cover plate 1202 and the pressure of the pusher locking member 1205, thus ensuring the stability of the connecting terminal installation, thereby ensuring the pre-connection of the connecting terminal and the cable, which facilitates the subsequent welding of the connecting terminal and the cable.

[0087] In this embodiment, the left and right sides of the base plate 1203 are also provided with buckles 1208 to hold the outer cover plate 1202 in place, and the outer cover plate 1202 is provided with flanges 242 on both sides. The left and right ends of the base plate 1203 are provided with slots, and the buckles 1208 are rotatably installed in the slots. Furthermore, the buckles 1208 have a small swing amplitude. Specifically, the slots are opened on the base plate 1203, and the buckles 1208 are installed in the slots through a first rotating shaft. The installation of the first rotating shaft is a conventional setting, such as opening a shaft hole in the front-back direction on the base plate 1203, with the shaft hole passing through the slot. At the bottom of the buckles 1208, there are also... A shaft hole is provided, and the shaft is fitted into the shaft hole. Furthermore, a torsion spring can be installed on the shaft. When the buckle 1208 is installed, the buckle 1208 contacts the inner wall of the slot under the action of the torsion spring, making the buckle 1208 a vertical device. The inner wall of the buckle 1208 is set with a rounded chamfer, and the bottom of the flange 242 is also set with a rounded shape. When the outer cover plate 1202 is pressed down, the flange 242 can apply an external force to the buckle 1208, thereby causing the two buckles 1208 to open outward. After the outer cover plate 1202 is closed, the buckles 1208 can be reset under the action of the torsion spring, thereby locking the flange 242.

[0088] In this embodiment, a limiting notch 1222 is provided at the rear end of the pusher plate 1221, and a protruding limiting block 1209 is provided on the bottom plate 1203. The limiting block 1209 is located in the limiting notch 1222. Since the pusher plate 1221 is slidably fitted with the sliding groove, the pusher plate 1221 can only move in the front-back direction. In order to prevent the pusher plate 1221 from exiting the sliding groove, the limiting block 1209 can block the pusher plate 1221, thereby preventing the pusher plate 1221 from exiting the sliding groove.

[0089] In this embodiment, pressure plates are detachably installed on the bottom plates 1203 on both sides of the pusher plate 1221. The pressure plates can hold the pusher plate 1221 in place. When installing the pusher plate 1221, the pusher plate 1221 is placed in the sliding groove, and then the pressure plates are installed on both sides of the pusher plate 1221. The pressure plates just need to contact the pusher plate 1221, or there is a certain gap between the pressure plates and the pusher plate 1221, so that the pressure plates will not affect the forward and backward movement of the pusher plate 1221.

[0090] In this embodiment, the pressing element 1204 is a glass bead, with more than half of the bead embedded in the bent portion of the outer cover plate 1202. Through the glass bead, the pressing element 1204 and the wedge-shaped surface 1223 achieve point-to-surface contact, ensuring that the pressing element 1204 applies a pushing force to the pusher plate 1221, causing the pusher plate 1221 to move forward. Furthermore, during the pressing process, the glass bead rolls along the wedge-shaped surface 1223, allowing the outer cover plate 1202 to push the pusher plate 1221 forward when the cover is closed. In the design, both the outer cover plate 1202 and the inner cover plate 1201 are L-shaped structures, with the bent portions of both the outer cover plate 1202 and the inner cover plate 1201 being their short sides. A notch is provided on the rear side wall of the base plate 1203, and a first rotating shaft is installed in the notch along the left-right direction. Both the outer cover plate 1202 and the inner cover plate 1201 are fitted onto this first rotating shaft. Of course, in order to facilitate the installation of the inner cover plate 1201 and the outer cover plate 1202, corresponding notches are provided on their bent portions, so that the bent portions of the outer cover plate 1202 and the inner cover plate 1201 are fitted onto the same first rotating shaft.

[0091] In this embodiment, the wire pressing mechanism 1100 includes a rotating cover plate 1101 and a wire carrier plate 1102. The wire carrier plate 1102 is mounted on the panel 1300 and has a wire groove 1103 for placing cables. After the rotating cover plate 1101 is closed, it presses the rear end of the cable into the wire groove 1103. A fixing support 1104 is provided on the panel 1300, located on the left side of the wire carrier plate 1102. One end of the rotating cover plate 1101 is rotatable. Installed on the fixed support 1104, the other end of the rotating cover 1101 is locked by a locking mechanism. In use, when the rotating cover 1101 is opened, the cable is first placed in the cable tray 1103, and then the position of the cable strip is adjusted so that the welding end of the cable is in the designated welding area. Then the rotating cover 1101 is closed, so that the rotating cover 1101 presses down on the cable, preventing the cable from moving back and forth. Finally, it is locked by the locking mechanism, thereby ensuring the stability of the cable position during transportation and welding.

[0092] In this embodiment, the locking mechanism includes a locking seat 1110. A limiting groove 1112 is formed at the top of the locking seat 1110, and a recess is formed at the bottom of the limiting groove 1112. The recess extends downwards, and a column 1108 is rotatably mounted within the recess. Preferably, a shaft hole is formed in the front-rear direction of the locking seat 1110, and a shaft rod passes through the shaft hole and through the column 1108. Therefore, the column 1108 can rotate relative to the locking seat 1110 by a certain degree. The top of the column 1108 extends upwards and protrudes from the limiting groove 1112. A rotating pressure head 1107 is rotatably mounted on the top. When the rotating cover 1101 is closed, the other end of the rotating cover 1101 is a locking end, which is located in the limiting groove 1112. The locking end has a notch through which the column 1108 passes, and the top of the locking end also has a variable diameter arc groove 1111. The rotating pressure head 1107 has an arc segment that rolls along the arc groove 1111. When the rotating pressure head 1107 is locked, the pressure block of the rotating pressure head 1107 presses against the upper surface of the rotating cover 1101. When the cover is closed, the rotating pressure head 1107 is... In the open state, the column 1108 is swung to the right, allowing the locking end to enter the space of the limiting groove 1112. Then, the column 1108 is reset. Preferably, the width of the locking end matches the width of the limiting groove 1112. Therefore, once the locking end enters the limiting groove 1112, the rotating cover 1101 cannot swing in the front-to-back direction. Then, the rotating pressure head 1107 is flipped, and its arc-shaped end rolls within the arc-shaped groove 1111. During this rolling process, because the arc-shaped groove 1111 has a variable diameter structure... The distance between the contact point of the arc end and the arc groove 1111 and the rotation center of the rotating pressure head 1107 is decreasing, so that the rotating pressure head 1107 applies downward pressure to the rotating cover plate 1101, thereby pressing the cable tightly. Preferably, after the rotating pressure head 1107 is installed in place, the included angle between the rotating pressure head 1107 and the column 1108 does not exceed °. At this time, the rotating pressure head 1107 has a certain self-locking effect and will not easily flip outward, thus ensuring the reliability of the rotating cover plate 1101 and the cable carrier plate 1102 closing.

[0093] In this embodiment, the locking mechanism also includes a latch 1109, which is located on the right side of the locking seat 1110. A mounting groove 113 is provided on the panel 1300, and the latch 1109 is rotatably installed in the mounting groove 113. A locking block is provided on the left end face of the latch 1109, and when the latch 1109 is locked, the lower end face of the locking block abuts against the limiting groove 1112. Furthermore, recessed grooves 1114 are provided on the front and rear side walls of the mounting groove 113, and the shaft on the latch 1109 is installed in the recessed groove 1114. A plug 1115 is installed on the panel 1300, and the bottom of the plug 1115 abuts against the shaft. Therefore, during installation, the shaft and the latch 1109 can be fitted together, and then the latch 1109 can be... 09 is placed in the mounting groove 113, and then the two ends of the shaft are pressed down with the plug 1115. Similarly, a torsion spring can also be installed on the shaft. Under the action of the torsion spring, the latch 1109 is in a vertical position. At this time, the lower end face of the locking block abuts against the limiting groove 1112. Of course, in order to avoid interference between the column 1108 and the locking block, an avoidance groove 15 can be opened on the locking block. Preferably, when the lower end face of the locking block abuts against the limiting groove 1112, the column 1108 also contacts the groove wall of the avoidance groove 15, or there is a slight gap between the column 1108 and the avoidance groove 15, so that the latch 1109 can limit the swing of the column 1108, thereby improving the reliability of the rotating cover 1101 and the wire plate 1102 closing.

[0094] In this embodiment, an anti-rotation block 1105 can also be rotatably installed on the panel 1300 located on the left side of the fixed support 1104. When the anti-rotation block 1105 is locked, a pin is provided on the right end face of the anti-rotation block 1105. When the anti-rotation block 1105 is locked, the pin is inserted between the fixed support 1104 and the rotating cover 1101. In this embodiment, the installation method of the anti-rotation block 1105 and the latch 1109 is the same, so the installation of the anti-rotation block 1105 will not be described in detail. By inserting the pin between the fixed support 1104 and the rotating cover 1101, when the rotating cover 1101 is closed, if the anti-rotation pin is not unlocked by external force, the rotating cover 1101 cannot rotate in the opposite direction, thereby ensuring the reliability of the wire pressing mechanism 1100.

[0095] In this embodiment, a wiring groove 1027 is also provided at the front end of the base plate 1203 to facilitate the passage of the welding end of the cable.

[0096] In this embodiment, in order to facilitate the removal of the fixture, an extraction mechanism 1400 is also installed at the left end of the panel 1300. The extraction mechanism 1400 includes a support plate, which is connected to the panel 1300, and handles are installed on the left and right sides of the support plate.

[0097] The robotic arm 530 first places the connecting terminal in the positioning groove 1206 to achieve the pre-positioning of the connecting terminal. Then, the inner cover plate 1201 is lowered, pressing down the middle of the connecting terminal. Next, the cable is placed in the cable groove 1103, so that the welding end of the cable overlaps with the welding end of the connecting terminal. Then, the cable is pressed down by rotating the cover plate 1101, and locked by rotating the cover plate 1101 through the locking mechanism. Finally, the outer cover plate 1202 is lowered and locked by the buckle 1208, thereby ensuring the reliability of the overlap between the welding end of the cable and the welding end of the connecting terminal.

[0098] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
