Description

Technical Field

[0001] The invention relates to the cutting and assembling of connecting terminals, in particular to a connecting terminal cutting and assembling device. Background Art

[0002] Connectors are usually composed of several parts and components, among which the core components include connecting terminals. During the production process, the connecting terminals are usually conveyed by strips, then stamped and formed on the strips several times, and then punched and separated from the strips to obtain independent connecting terminals.

[0003] Since the connection terminals are usually not regular parts, such as the springs of the connection terminals are bending mechanisms, it is difficult for conventional cutting devices to achieve continuous feeding of the connection terminals. In order to improve production efficiency, it is necessary to continuously cut the connection terminals, and then grab the connection terminals and place them in the jig for assembly. However, the current cutting devices have the following problems after cutting: 1. After cutting, the material cannot be taken directly and needs to be manually arranged and packaged again, resulting in low production efficiency; 2. The connection terminals are high-precision products. Free falling will cause the connection terminals to deform and become uncontrollable. Manual arrangement will also cause secondary contamination of the product, affecting its transmission performance. 3. The structure of the connection terminal is not on the same horizontal dimension as the material strip, which makes it inconvenient to feed the material strip continuously.

[0004] However, since the structure of the connecting terminal itself is relatively small, it is difficult to clamp it. In addition, the middle part of the connecting terminal is a plastic package, and its structural strength is not high. The clamping force requirement is also very high, and during the clamping process, the robot cannot contact the conductive parts on the connecting terminal. Most importantly, since the structure of the connecting terminal itself is relatively small, the grabbing hole on the cutting mold is also small, which leads to the width of the clamping end of the robot is also small, and the robot has to go deep into the concave mold of the cutting mold to clamp the connecting terminal, which leads to the length of the clamping end of the robot is also small. In addition, during the clamping process, the positioning accuracy requirement of the robot is very high. Therefore, when the length and width are relatively large, it is difficult for the current robot to meet the clamping accuracy of the clamping end. Summary of the invention

DETAILED DESCRIPTION

[0018] like Figure 1 and Figure 2 As shown, a connecting terminal cutting and assembling device includes a workbench, on which a cutting module 140, a clamping module 150 and an assembling module 160 are installed. The cutting module 140 disassembles the connecting terminal, the clamping module 150 grabs the cut connecting terminal and places it on the assembling module 160, and the assembling module 160 overlaps the connecting terminal and the cable, thereby realizing the cutting and assembly of the connecting terminal.

[0019] In this embodiment, if Figure 3~Figure 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 and downward. An upper mold core 10 is installed on the lower surface of the upper module 100, and an upper mold core 10 is installed on the upper surface of the lower module 200. The upper mold core 10 and the lower mold core 20 are 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 material taking trough 16 is provided on the upper mold core 10, and an upper tool 14 is installed on the upper mold core 10. The upper tool 14 is located on the left side of the material taking trough 16. An avoidance groove 15 is provided on the upper mold core 10, and the avoidance groove 15 is located on the right side of the material taking trough 16, and the avoidance groove 15 is adjacent to the taking trough 16. The material trough 16 is connected, and a rotatable cam pressing block 13 is installed in the avoidance groove 15. The cam pressing block 13 includes a lever 131. The head of the lever 131 is provided with a pressure head 133 made of soft material. A rotating shaft 135 is provided at the bottom corner of the lever 131. Both ends of the rotating shaft 135 are rotatably installed on the upper mold core 10. An inner groove 136 concave inwardly is also provided on the inner side of the lever 131. The rotating shaft 135 passes through the inner groove 136. A torsion spring 134 is also installed on the rotating shaft 135 located in the inner groove 136. One torsion arm of the torsion spring 134 abuts against the bottom of the inner groove 136, and the other torsion arm of the torsion spring 134 abuts against the side wall of the avoidance groove 15. A rotatable roller 132 is installed at the tail of the lever 131.The lower die core 20 is provided with a lower cutter 24 for cutting in cooperation with the upper cutter 14. The lower die core 20 is also provided with a cam push rod 23 for rotating the cam pressing block 13. The cam push rod 23 is located on one side of the lower cutter 24. The upper die core 10 is provided with a plug hole for inserting the cam push rod 23 into the avoidance groove 15. When the upper die core 10 and the lower die core 20 are molded together, the cam push rod 23 is inserted into the avoidance groove 15 from the plug hole. When the cam push rod 23 contacts the roller 132, the cam push rod 23 exerts a push force on the roller 132. The lever 131 is rotated around the rotating shaft 135, so that the pressing head 133 presses the middle part of the connecting terminal. When the lever 131 rotates, the torsion spring 134 generates a torsion force. When the upper mold core 10 and the lower mold core 20 are demoulded, the lever 131 is reset under the action of the torsion spring 134. In this embodiment, a resisting surface is provided on the avoidance groove 15. When the lever 131 contacts the resisting surface under the torsion force of the torsion spring 134, the lever 131 is completely located in the avoidance groove 15. During the mold closing process, After the pressure head 133 contacts the middle of the connection terminal, the pressure head 133 presses the connection terminal, and then as the upper mold core 10 and the lower mold core 20 are molded, the pressure head 133 is deformed. Preferably, the pressure head 133 is made of rubber or silicone material. Through the deformation and compression of the pressure head 133, it is ensured that the pressure head 133 can continuously apply pressure to the connection terminal, ensuring the clamping force of the connection terminal. Then, when the upper cutter 14 and the lower cutter 24 move relatively again, the connection terminal is separated from the material strip to achieve cutting. Since the connection terminal is pressed during the cutting process, the connection terminal will not shake during the cutting process, thereby ensuring the cutting quality of the connection terminal. Moreover, during demolding, since the pressure head 133 is made of soft material, the pressure of the pressure head 133 on the connection terminal is gradually reduced, thereby preventing the connection terminal from suddenly losing pressure, thereby ensuring that the connection terminal will not shake, avoiding the connection terminal from bumping, ensuring the position of the connection terminal is fixed, and facilitating the grabbing of the connection terminal. ;

[0020] In this embodiment, after the ram 133 contacts the middle of the connector, the upper mold assembly 100 continues to move downward as the mold is closed. Preferably, before the mold is closed, 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 mold assembly 100 moves downward, the roller 132 has rolled to the side wall of the cam push rod 23, and the pressing force of the ram 133 on the connecting terminal remains constant, thereby preventing the ram 133 from crushing the connecting terminal and preventing the ram 133 from being damaged due to excessive deformation, thereby ensuring the service life of the ram 133.

[0021] In this embodiment, the upper mold core 10 includes a first plate body 11 and a second plate body 12 that are detachably connected. Preferably, the first plate body 11 and the second plate body 12 are detachably connected by a locking screw. The upper tool 14 is installed between the first plate body 11 and the second plate body 12, and the blade of the upper tool 14 protrudes from the lower surface of the second plate body 12. Furthermore, a limit stop 141 is provided on the top of the upper tool 14, and convex ribs 142 are provided on both sides of the upper tool 14. A notch matching the upper tool 14 and a limit groove 1112 matching the convex rib 142 are provided on the second plate body 12, and a groove corresponding to the limit stop 141 is provided at the bottom of the first plate body 11. When the first plate body 11 and the second plate body 12 are installed, the limit stop 141 is stuck in the groove, and the convex rib 142 is stuck in the limit groove 1112, thereby avoiding relative displacement between the upper tool 14 and the upper mold core 10.

[0022] In this embodiment, grooves are provided at the contact surfaces of the first plate body 11 and the second plate body 12, and the two grooves constitute an avoidance groove 15. A socket is provided on the second plate body 12 for facilitating the insertion of the cam push rod 23. Furthermore, the groove on the second plate body 12 is a through groove that passes through in the up and down directions, and then the bottom of the groove is covered by a cover plate 19, and a socket is provided on the cover plate 19. The cover plate 19 and the second plate body 12 are locked by locking screws. When the cover plate 19 is installed, the cover plate 19 does not protrude from the lower surface of the second plate body 12, and the corresponding torsion arm on the torsion spring 134 abuts against the cover plate 19.

[0023] In this embodiment, the lower mold core 20 includes a detachable third plate body 21 and a fourth plate body 22, and the third plate body 21 and the fourth plate body 22 are also detachably connected by locking screws. The lower tool 24 and the bottom of the cam push rod 23 are installed between the third plate body 21 and the fourth plate body 22. A blanking groove 25 is opened on the third plate body 21, and the blanking groove 25 extends downward and passes through the fourth plate body 22, and the protruding part of the upper tool 14 can be inserted into the blanking groove 25. Therefore, when the mold is closed, the upper tool 14 enters the blanking groove 25, and the cut end of the connecting terminal is received by the lower tool 24, thereby avoiding deformation of the cut end of the connecting terminal.

[0024] In this embodiment, a notch is provided on the third plate body 21 near the blanking groove 25, and slots 215 are provided on the two side walls of the notch. The lower tool 24 is installed in the notch. Blocks 241 cooperating with the slots 215 are provided on both sides of the lower tool 24. A storage groove 243 is provided on the upper surface of the lower tool 24 away from the cutting edge. A receiving groove 212 is provided on the upper surface of the third plate body 21. The receiving groove 212 is connected with the storage groove 243. The side wall of the receiving groove 212 near the storage groove 243 is a slope surface 213. A plurality of blocking blocks 214 are provided on the slope surface 213, thereby forming a plurality of separation grooves on the slope surface 213. The bottom of the lower tool 24 A flange 242 is provided at the part, and the flange 242 is pressed between the third plate body 21 and the fourth plate body 22. In this embodiment, a section of material strip has a plurality of 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 piece of the connecting terminal is located in the accommodating groove 212, and the two adjacent connecting terminals are separated by the blocking block 214, thereby avoiding collision between the connecting terminals. Moreover, when loading, the relative position between the two connecting terminals can also be guaranteed, so that the spring pieces of the connecting terminals can independently enter the corresponding separation grooves.

[0025] In this embodiment, at least two groups of elastic columns 18 are also installed on the upper mold core 10, and at least one group of elastic columns 18 is located on the front side of the upper tool 14, and at least one group of elastic columns 18 is located on the rear side of the material trough 16. The elastic columns 18 include step columns, compression springs and plugs 1115. A step hole is opened on the second plate body 12, and the step column is installed in the step hole. A corresponding through hole is opened on the first plate body 11, and a plug 1115 is installed in the through hole. Preferably, the plug 1115 is threadedly connected to the through hole, and the compression spring is compressed between the step column and the plug 1115. When the mold is closed, the elastic columns 18 press the material strip so that the material strip does not move, thereby ensuring the problem of connecting terminals on the material strip. Preferably, each group of elastic columns 18 has two, and then when the mold is closed, the four corners of the material strip can be pressed, thereby preventing the material strip from moving, thereby ensuring the cutting quality of the connecting terminals.

[0026] In this embodiment, since the connection terminals and the material strip are not on the same horizontal dimension, it is difficult to feed the connection terminals during the horizontal movement of the material strip. Fig.17As shown, the lifting assembly 300 includes a base 500 and a translation cylinder 301, the translation cylinder 301 is installed on the base 500, and the top of the base 500 is provided with a pair of guide grooves 304, the guide grooves 304 extend in the left and right directions, and a sliding rail 303 is slidably matched in 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, and a climbing slope 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 bodies 203 are installed on the side plates 202. When the sliding rail 303 moves left and right, the rolling bodies 203 roll along the surface of the sliding rail 303. Since the sliding rail 303 has a climbing slope 305, the sliding rail 303 has an upper rail surface and a lower rail surface. When the rolling body 203 moves from the lower rail surface to the upper rail surface, the lower mold assembly 200 rises, and when the rolling body 203 moves from the upper rail surface to the lower rail surface, the lower mold assembly 200 descends. Therefore, when feeding, the rolling body 203 is located on the lower rail surface. At this time, the lower mold assembly 200 is in the downstroke, so that the lower mold core 20 is away from the material belt, thereby making room for the forward and backward movement of the connecting terminal. After the material belt drives the connecting terminal to enter the cutting station, the translation cylinder 301 works again, so that the rolling body 203 moves from the lower rail surface to the upper rail surface. At this time, the lower mold assembly 200 moves upward, so that the middle part of the connecting terminal enters the storage groove 243, and the spring piece of the connecting terminal is located in the dividing groove, thereby realizing the continuous feeding of the connecting terminal driven by the material belt, thereby ensuring the cutting efficiency of the connecting terminal.

[0027] In this embodiment, if Fig.18As shown, the lifting assembly 400 includes a base plate 1203, on which a lifting cylinder 401 and a rotating support 403 are installed. The rotating support 403 is located on one side of the lifting cylinder 401, and a rotating plate 402 is rotatably installed on the rotating support 403. One end of the rotating plate 402 is located above the telescopic axis of the lifting cylinder 401, and the lifting of the lifting cylinder 401 causes the rotating plate 402 to rotate around the rotating support 403. The other end of the rotating plate 402 is provided with a pair of cantilevers 403, and the inner side of the cantilever 403 is provided with a rotatable lower pressure wheel 405. At least two lower pull rods 104 are provided on the upper mold assembly 100, and the lower ends of the lower pull rods 104 pass through the lower mold assembly 200 and It is connected to a lower pull-down plate 406, and a lower pull-down groove 407 corresponding to the lower pressure wheel 405 is provided on the lower pull-down plate 406. The lower pressure wheel 405 rolls in the lower pull-down groove 407. When the piston rod of the jacking assembly 400 is extended, the rotating plate 402 rotates around the rotating support 403, and the other end of the rotating plate 402 swings downward. In the process of the lower pressure wheel 405 swinging downward, while rolling along the lower pull-down groove 407, it also applies a downward pulling force to the lower pull-down plate 406, thereby causing the lower pull-down plate 406 to move downward. After the lower pull-down plate 406 moves downward, the upper mold assembly 100 is driven downward through the lower pull rod 104, thereby realizing the mold closing of the upper mold assembly 100 and the lower mold assembly 200, and completing the cutting of the connecting terminal.

[0028] In this embodiment, the upper mold assembly 100 also includes an upper mold plate 101, and the upper mold core 10 is installed on the lower surface of the upper mold plate 101. The lower mold assembly 200 also includes a lower mold plate 201, and the lower mold core 20 is installed on the upper surface of the lower mold plate 201. The top of the lower pull rod 104 is installed on the upper mold plate 101, and the bottom of the lower pull rod 104 passes through the lower mold plate 201 and is connected to the lower pull plate 406. At least two guide columns 103 are also provided on the upper mold plate 101. The bottom of the guide column 103 passes through the lower mold plate 201. The guide column 103 located between the upper mold plate 101 and the lower mold plate 201 is also provided with a reset spring 102. When the upper mold plate 101 is in the downward process, the reset spring 102 is compressed, and when the lifting cylinder 401 is reset, the upper mold assembly 100 is in the reset spring. The upper die assembly 100 and the lower die assembly 200 are demoulded by the return spring 102. After the return spring 102 is installed, the return spring 102 is in a compressed state. When the upper die assembly 100 is stationary, when the rolling body 203 moves from the upper rail surface to the lower rail surface, the return spring 102 will also exert a downward pressure on the lower die assembly 200, causing the lower die assembly 200 to move downward, thereby ensuring the reliability of the downward movement of the lower die assembly 200. In the initial state, although the return spring 102 can also exert an upward thrust on the upper die assembly 100, after the thrust is transmitted to the lower pressure wheel 405 through the lower pull-down groove 407 on the lower pull-down plate 406, one end of the rotating plate 402 is in contact with the telescopic shaft of the lifting cylinder 401, thereby preventing the upper die assembly 100 from moving upward in the initial state.

[0029] In this embodiment, a pre-positioning groove 211 is further provided on the upper surface of the third plate body 21. The pre-positioning groove 211 is a step groove, and the pre-positioning groove 211 is located at the front end of the accommodating groove 212. When the upper section of the material strip is cut, the connecting terminal of the next section of the material strip is located in the pre-positioning groove 211. In this way, the blank area of ​​the two sections of the material strip can be shortened, thereby saving raw materials.

[0030] In this embodiment, a positioning column 17 is also installed on the upper mold core 10, and the positioning column 17 is located on the front side of the elastic column 18. A positioning hole 216 corresponding to the positioning column 17 is opened on the lower mold core 20. Through the positioning column 17 and the positioning hole 216, the accuracy of the mold closing between the upper mold core 10 and the lower mold core 20 can be further ensured, thereby ensuring the quality of the cutting of the connecting terminal.

[0031] In this embodiment, one end of the material tape is a feeding mechanism 130, and the other end of the material tape is a traction mechanism. The feeding mechanism 130 transports the connection terminals on the material tape to the cutting module 140, and the traction mechanism pulls the cut material tape out of the cutting module 140. In this embodiment, the feeding mechanism 130 and the traction mechanism are both existing technologies, so they will not be described in detail.

[0032] When the cutting module 140 cuts the connection terminals, the material strip moves backward under the action of the feeding mechanism 130 and the traction mechanism. When the lower module 200 needs to feed, the translation cylinder 301 works to move the rolling body 203 from the upper rail surface to the lower rail surface. When the rolling body 203 rolls down on the climbing slope 305, the lower module 200 moves downward, thereby driving the lower mold core 20 downward, so that the material strip is separated from the lower mold core 20, thereby making room for the feeding of the connection terminals. Then the traction mechanism works to make the connection terminals on the material strip enter the cutting station, and then the translation cylinder 301 is used to move the rolling body 203 from the upper rail surface to the lower rail surface. The cylinder 301 is reset, the rolling body 203 rolls from the lower rail surface to the upper rail surface, the lower mold assembly 200 moves upward, and the connecting terminal enters the corresponding receiving groove 212 and the storage groove 243, and then the lifting cylinder 401 moves upward, the rotating plate 402 rotates, so that the lower pressure wheel 405 applies a downward pulling force to the lower pressure plate, and the lower pressure plate moves downward, so that the reset spring 102 is further compressed. During the downward movement of the lower pressure plate, the upper mold assembly 100 also moves downward, so that the upper mold assembly 100 and the lower mold assembly 200 are molded together. When the mold is closed, the cam push rod 23 is first inserted into the jack and then contacts the roller 132. As a result, the lever 131 rotates, and the pressure head 133 gradually approaches the middle of the connecting terminal. When the pressure head 133 contacts the middle of the connecting terminal, as the mold is closed, the pressure head 133 continuously applies pressure to the middle of the connecting terminal, thereby ensuring the clamping force of the connecting terminal and preventing the connecting terminal from moving during cutting, thereby ensuring the cutting quality. After the mold is closed, the upper tool 14 and the lower tool 24 cooperate to cut the connecting terminal and the material strip, and then the lifting cylinder 401 is reset. During the reset process, the upper mold assembly 100 is elastically reset by the reset spring 102. Under the action of the restoring force, the upper mold group 100 moves upward and drives the pull-down plate 406 upward, so that the rotating plate 402 rotates 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 mold group 100 stops moving upward. At this time, the upper mold group 100 returns to the initial state, and the upper mold group 100 and the lower mold group 200 are demoulded. At this time, the connecting terminal is located on the lower mold core 20, and then inserted from the material trough 16 through the clamping module 150, and the connecting terminal is clamped to be taken out from the material trough 16, and then the next cutting is carried out.

[0033] In this embodiment, the clamping module 150 includes a rotating mechanism and a linear moving module 510. The rotating mechanism is installed on the workbench. The rotating mechanism is a prior art and will not be described in detail. The linear moving module 510 is installed on the rotating mechanism. Further, a sliding plate 520 is provided on the linear moving module. A manipulator 530 is installed on the sliding plate 520. The linear moving module 510 is a prior art and will not be described in detail. In this embodiment, the linear moving module 510 drives the sliding plate 520 to move up and down, that is, the manipulator 530 moves up and down with the sliding plate 520. When the sliding plate 520 moves to the lower stroke, the manipulator 530 works to clamp the connector, and then the sliding plate 520 moves to the upper stroke, thereby taking the connector out vertically from the die.

[0034] In this embodiment, if Figure 19 to Figure 23As shown, the manipulator 530 includes a gripper cylinder 51, and the execution end of the gripper cylinder 51 is connected to a clamp 53. In the present embodiment, the gripper cylinder 51 is a double-headed gripper. When the gripper cylinder 51 works, the two clamps 53 move toward or away from each other, thereby realizing the clamping and release of the connector. Furthermore, limiting members 52 are installed in pairs on the outer wall of the gripper cylinder 51. The two limiting members 52 are arranged opposite to each other, and two raised guard plates and convex columns 522 are arranged on the opposite surfaces of the limiting members 52. The convex columns 522 are located between the two guard plates, and the two limiting members 52 surround a cavity, which is divided into two limiting cavities 521 by the two convex columns 522. The clamps 53 are slidably installed in the corresponding limiting cavities 521, and the clamps 53 can slide left and right relative to the limiting members 52. A limiting screw 524 is also installed on the guard plate, and the clamping end of the clip 53 is located below the limiting cavity 521. A plurality of positioning teeth 531 are arranged at intervals at the bottom of the clamping end of one of the clips 53. By adjusting the limiting screw 524, the stroke of the clip 53 in the limiting cavity 521 can be changed, so that the maximum distance between the two clips 53 can be adjusted. Moreover, in the present embodiment, when the two clips 53 are at the shortest distance, the two clips 53 just clamp the connector, and the width of the protrusion 522 determines the shortest distance between the two clips 53. That is to say, when designing, the width of the protrusion 522 can be reasonably designed according to the model of the connection terminal, so as to ensure the stability of the clamping force of the clip 53 on the connection terminal, thereby ensuring the reliable clamping of the connection terminal. The clamp 53 is movable in a direction opposite to the left and right sides of the clamp 53. The clamp 53 is movable in a direction opposite to the right and left sides of the clamp 53. The clamp 53 is movable in a direction opposite to the left and right sides of the clamp 53. 530 needs to extend into the concave mold of the cutting mold to clamp the connecting terminal. Therefore, the size of the clip 53 needs to be longer and smaller. In other words, the length-to-width ratio of the clip 53 is relatively large, and needs to be at least times or more. With such a large length-to-width ratio, when the top of the clip 53 moves left and right, if its straightness cannot be guaranteed, the clamping accuracy of its clamping end will be further magnified, thereby resulting in the accuracy of the clamping end of the clip 53 cannot be guaranteed, and then the connecting terminal cannot be reliably clamped. In this embodiment, the top of the clip 53 is constrained by the dovetail groove 54 and the dovetail block 55 and the limit cavity 521, and can be longer and smaller than the traditional clip 53, that is, the length-to-width ratio can reach more than times, so it can be used in narrow spaces and smaller product usage environments.Thus, the connection terminal in the concave die of the cutting die can be clamped.

[0035] In this embodiment, a connecting arm 532 is provided on the top of the clip 53, and a mounting groove 533 is opened on the connecting arm 532. A connecting block 56 is provided on the dovetail block 55. The connecting block 56 is detachably installed in the mounting groove 533, so as to facilitate the replacement of the clip 53, so that it can be suitable for more types of connecting terminals. Furthermore, part of the connecting block 56 is located on the outside of the mounting groove 533, and a gasket is installed between the connecting block 56 and the mounting groove 533. In this embodiment, according to different connecting terminals, the maximum spacing of the clip 53 in the limiting cavity 521 can be changed by adding or removing gaskets and adjusting the limit screws 524.

[0036] In this embodiment, a threaded through hole is opened in the boss 522, and the two limit members 52 are locked by locking screws installed in the threaded through holes. The locking of the locking screws ensures the stability of the structure of the limit cavity 521, and further ensures that the limit cavity 521 limits the clamp 53. Furthermore, the threaded through hole of one of the bosses 522 is a stepped hole, and the head of the locking screw is located in the large hole of the stepped hole, thereby making the structure of the entire limit member 52 simpler and occupying less space.

[0037] 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 in sequence from top to bottom. The thickness of the thick-walled section 534 and the shortened section 535 are the same, 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 narrow and long, which is convenient for insertion into the The thin-walled section 536 can be used in a small and deep deep hole. Furthermore, the outer side of the shortened section 535 of one clip 53 is a wedge-shaped surface 1223, which can facilitate the clip 53 to extend into the deep hole. The thickness of the wedge-shaped surface 1223 decreases from top to bottom, which can ensure that the clip 53 extends into the deep hole while increasing the structural strength of the clip 53. The positioning teeth 531 are installed at the bottom of the shortened section 535 of the other clip 53. In this embodiment, as shown in FIG. Fig.35 and Fig.36As shown, the middle part of the connecting terminal is a plastic sealing part, and the plastic sealing parts are connected in a row. There is a positioning groove 1206 between two adjacent plastic sealing parts, and the positioning tooth 531 is stuck in the positioning groove 1206. When clamping, the manipulator 530 moves downward, and the positioning tooth 531 is stuck in the positioning groove 1206. Then the clamping claw cylinder 51 works to make the two clamps 53 approach each other, so that the two clamps 53 clamp the plastic sealing part, and then the manipulator 530 moves upward to clamp the connecting terminal, and then the rotating mechanism rotates to rotate the connecting terminal to the top of the assembly module 160. Finally, the manipulator 530 moves downward to place the connecting terminal on the assembly module 160.

[0038] As an important part of the connector, the connecting terminal itself has a relatively small structure, and the middle part of the connecting terminal is a plastic package connected side by side, and its structural strength is not high. During the installation process, it is easy to deform, such as bending. The deformed connecting terminal will affect the lap performance with the cable, so the requirements for the assembly module are relatively high. In this embodiment, if Figure 25~Figure 34 As shown, the assembly module 160 includes a panel 1300, on which a wire crimping mechanism 1100 and a pushing mechanism 1200 are installed. The wire crimping mechanism 1100 and the pushing mechanism 1200 are arranged relative to each other. The wire crimping mechanism 1100 presses the cable, and the pushing mechanism 1200 presses the connecting terminal, and makes the welding end of the connecting terminal overlap with the welding end of the cable. After the welding end of the connecting terminal and the welding end of the cable overlap, the fixture is moved as a whole to the next station.

[0039] In this embodiment, if Fig.26 and Fig. 27 As shown, the pushing mechanism 1200 includes a bottom plate 1203, which is mounted on a panel 1300. A positioning groove 1206 is provided at one end of the bottom plate 1203 close to the wire pressing mechanism 1100. A positioning member 1210 for pre-positioning the connection terminal is provided in the positioning groove 1206. A groove is provided on one side of the positioning member 1210. In this embodiment, as shown in FIG. Fig.35 and Fig.36 As shown, the middle part of the connecting terminal is a square block, a column is arranged at the bottom of the square block, and an open groove matching the positioning piece 1210 is opened on the side wall at the bottom of the square block. The manipulator 530 clamps the connecting terminal and places it in the positioning groove 1206. At this time, the column enters into the groove to achieve one-time positioning, and then as the connecting terminal is lowered, the positioning piece 1210 partially enters into the open groove, thereby positioning the connecting terminal in the left and right directions, but at this time, the connecting terminal can also move forward.

[0040] In this embodiment, a sliding groove is provided on the base plate 1203 located at the rear side of the positioning groove 1206, and a push lock 1205 is slidably installed in the sliding groove. The push lock 1205 can slide forward and backward relative to the sliding groove, and a rotatable inner cover plate 1201 and an outer cover plate 1202 are installed at the rear end of the base plate 1203. By rotating the inner cover plate 1201, 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 directions. By covering the inner cover plate 1201 down, the inner cover plate 1201 covers the middle part of the connecting terminal, so that the connecting terminal can be pre-pressed in the up and down directions, thereby realizing the pre-positioning of the connecting terminal in the up and down directions.

[0041] In this embodiment, the push lock 1205 includes a push plate 1221, which is slidably mounted in the sliding groove. The front end of the push plate 1221 is provided with a locking tooth 1224 protruding upward, and the top of the locking tooth 1224 is provided with a tooth head 1225 extending forward. The lower surface of the tooth head 1225 forms a limiting step 1226. The rear side wall of the push plate 1221 is a wedge-shaped surface 1223, and the rear end of the outer cover plate 1202 is provided. There is a pressing piece 1204, the outer cover plate 1202 is rotated so that the outer cover plate 1202 covers the inner cover plate 1201, and during the rotation of the outer cover plate 1202, the pressing piece 1204 presses the wedge-shaped surface 1223, so that the push plate 1221 moves forward. In this embodiment, there is a step groove between two adjacent middle parts of the connecting terminal, and the top of the step groove forms a positioning groove 1206. When the outer cover plate 1202 is in the process of closing the cover, the pressing piece 1204 pushes the push plate 1221 to move forward, and the tooth head 1225 is inserted into the gap between the two adjacent middle parts of the connecting terminal, that is, the tooth head 1225 is stuck in the step groove, and the limiting step 1226 abuts against the upper surface of the step groove. In the process of the push plate 1221 moving forward, the push plate 1221 pushes the middle part of the connecting terminal forward for a distance, so that the rear side wall of the positioning member 1210 abuts against the open groove, and when the outer cover 1202 is closed, the front, back, left, right, up and down positions of the connecting terminal are fixed, thereby 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 1202 and the abutment of the push lock 1205, thereby ensuring the stability of the installation of the connecting terminal, thereby ensuring the pre-connection of the connecting terminal and the cable, and facilitating the subsequent welding of the connecting terminal and the cable.

[0042] In this embodiment, buckles 1208 for clamping the outer cover 1202 are further provided on the left and right sides of the bottom plate 1203, and flanges 242 are provided on both sides of the outer cover 1202. Slots are provided at the left and right ends of the bottom plate 1203, and the buckles 1208 are rotatably installed in the slots. Furthermore, the buckles 1208 have a small swing. Specifically, a slot is provided on the bottom plate 1203, and the buckle 1208 is installed in the slot through a first rotating shaft. The installation of the first rotating shaft belongs to a conventional setting, such as providing an axial hole in the front-to-back direction of the bottom plate 1203, the axial hole passes through the slot, and at the bottom of the buckle 1208 An axial hole is provided, and the shaft rod is mounted in the axial hole. Furthermore, a torsion spring can be installed on the shaft rod. When the buckle 1208 is installed, the buckle 1208 contacts the inner wall of the slot hole under the action of the torsion spring, so that the buckle 1208 is a vertical device, and the inner wall of the buckle 1208 is set to be an arc chamfer, and the bottom of the flange 242 is also set to be an arc shape. When the outer cover plate 1202 is pressed down, the flange 242 can exert an external force on the buckle 1208, thereby causing the two buckles 1208 to expand outward. After the outer cover plate 1202 is closed, the buckle 1208 can be reset under the action of the torsion spring, thereby locking the flange 242.

[0043] In this embodiment, a limiting notch 1222 is provided at the rear end of the push plate 1221, and a raised limiting block 1209 is provided on the bottom plate 1203. The limiting block 1209 is located in the limiting notch 1222. Since the push plate 1221 and the sliding groove are installed in a sliding fit, the push plate 1221 can only move in the front and rear directions. In order to prevent the push plate 1221 from withdrawing backward from the sliding groove, the limiting block 1209 can block the push plate 1221, thereby preventing the push plate 1221 from withdrawing backward from the sliding groove.

[0044] In this embodiment, a pressure plate is detachably installed on the bottom plate 1203 on the left and right sides of the push plate 1221, and the pressure plate can press the push plate 1221. When installing the push plate 1221, the push plate 1221 is placed in the sliding groove, and then the pressure plate is installed on the left and right sides of the push plate 1221. The pressure plate just contacts with the push plate 1221, or there is a certain gap between the pressure plate and the push plate 1221, so that the pressure plate will not affect the forward and backward movement of the push plate 1221.

[0045] In this embodiment, the top pressing member 1204 is a glass bead, and more than half of the glass bead is embedded in the bent portion of the outer cover plate 1202. Through the glass bead, the top pressing member 1204 and the wedge-shaped surface 1223 are in point-to-surface contact, thereby ensuring that the top pressing member 1204 applies a thrust to the push plate 1221, so that the push plate 1221 moves forward, and during the top pressing process, the glass bead can roll along the wedge-shaped surface 1223, so that when the outer cover plate 1202 is closed, the push plate 1221 can be pushed forward by the glass bead. In this embodiment, In the figure, the outer cover plate 1202 and the inner cover plate 1201 are both L-shaped structures, and the bent parts of the outer cover plate 1202 and the inner cover plate 1201 are their short sides, and a notch is opened on the rear side wall of the bottom plate 1203, and a first rotating shaft is installed in the notch along the left and right directions, and the outer cover plate 1202 and the inner cover plate 1201 are both mounted on the 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 opened on their bent parts, so that the bent parts of the outer cover plate 1202 and the inner cover plate 1201 are both mounted on the same first rotating shaft.

[0046] In this embodiment, the wire pressing mechanism 1100 includes a rotating cover plate 1101 and a wire carrying plate 1102, the wire carrying plate 1102 is installed on the panel 1300, and a wire groove 1103 for placing the cable is opened on the wire carrying plate 1102. After the rotating cover plate 1101 is closed, the rotating cover plate 1101 presses the rear end of the cable into the wire groove 1103. A fixed support 1104 is provided on the panel 1300, and the fixed support 1104 is located on the left side of the wire carrying plate 1102. One end of the rotating cover plate 1101 can rotate. Installed on the fixed support 1104, the other end of the rotating cover 1101 is locked by a locking mechanism. When in use, when the rotating cover 1101 is opened, the cable is first placed in the cable groove 1103, and then the position of the strip cable is made so that the welding end of the cable is in the designated welding area, and then the rotating cover 1101 is closed, so that the rotating cover 1101 presses the cable and the cable cannot move forward and backward, and finally locked by the locking mechanism, thereby ensuring the stability of the position of the cable during transportation and welding.

[0047] In this embodiment, the locking mechanism includes a locking seat 1110, a limiting groove 1112 is provided at the top of the locking seat 1110, a groove is provided at the bottom of the limiting groove 1112, the groove extends downward, and a column 1108 is rotatably installed in the groove. Preferably, an axial hole is provided in the front-to-back direction of the locking seat 1110, a shaft rod is passed through the axial hole, and the shaft rod passes through the column 1108, so that the column 1108 can rotate to a certain extent relative to the locking seat 1110, and the top of the column 1108 extends upward and protrudes from the limiting groove 1112, and the column 1108 A rotating pressure head 1107 is rotatably installed on the top. When the rotating cover plate 1101 is closed, the other end of the rotating cover plate 1101 is a locking end, which is located in the limiting groove 1112. A notch is provided on the locking end for the column 1108 to pass through. A variable diameter arc groove 1111 is also provided on the top of the locking end. 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 is pressed on the upper surface of the rotating cover plate 1101. When the cover is closed, the rotating pressure head 1107 is at the position of the rotating pressure head 1107. In the open state, the column 1108 is swung to the right to allow the locking end to enter the space of the limiting groove 1112, and then the column 1108 is reset. Preferably, the width of the locking end matches the width of the limiting groove 1112. Therefore, when the locking end enters the limiting groove 1112, the rotating cover 1101 cannot swing in the front and rear directions. Then, the rotating pressure head 1107 is turned over, and the arc end of the rotating pressure head 1107 rolls in the arc groove 1111. During the rolling process, since the arc groove 1111 is a variable diameter structure The distance between the contact point between the arc end and the arc groove 1111 and the rotation center of the rotating pressure head 1107 is reduced, so that the rotating pressure head 1107 applies downward pressure on the rotating cover plate 1101, so that the rotating cover plate 1101 presses the cable. Preferably, after the rotating pressure head 1107 is installed in place, the 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 turn outward, thereby ensuring the reliability of the closing of the rotating cover plate 1101 and the wire carrier plate 1102.

[0048] In this embodiment, the locking mechanism also includes a lock buckle 1109, which is located on the right side of the locking seat 1110. A mounting groove 113 is provided on the panel 1300. The lock buckle 1109 can be rotatably installed in the mounting groove 113. A locking block is provided on the left end face of the lock buckle 1109, and when the lock buckle 1109 is locked, the lower end face of the locking block abuts against the limiting groove 1112. Furthermore, sinking grooves 1114 are provided on the front and rear side walls of the mounting groove 113. The shaft rod on the lock buckle 1109 is installed in the sinking groove 1114, and a plug 1115 is installed on the panel 1300. The bottom of the plug 1115 abuts against the shaft rod. Therefore, during installation, the shaft rod and the lock buckle 1109 can be assembled together, and then the lock buckle 1109 can be fastened. 09 is placed in the installation groove 113, and then the two ends of the shaft rod are pressed with the plug 1115. Similarly, a torsion spring can also be installed on the shaft rod. Under the action of the torsion spring, the lock buckle 1109 is in a vertical device. At this time, the lower end face of the locking block is in contact with 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 is in contact with the limiting groove 1112, the column 1108 is also in contact with 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 lock buckle 1109 can limit the swing of the column 1108, thereby improving the reliability of the closing of the rotating cover plate 1101 and the wire carrier plate 1102.

[0049] In the present embodiment, a stop block 1105 is rotatably installed on the panel 1300 located on the left side of the fixed support 1104. When the stop block 1105 is locked, a pin block is provided on the right end face of the stop block 1105, and when the stop block 1105 is locked, the pin block is inserted into the gap between the fixed support 1104 and the rotating cover 1101. In the present embodiment, the installation method of the stop block 1105 is consistent with that of the lock buckle 1109, so the installation of the stop block 1105 is not repeated, and the pin block is inserted into the gap between the fixed support 1104 and the rotating cover 1101. When the rotating cover 1101 is closed, if the stop 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.

[0050] In this embodiment, a wiring groove 1027 is further provided at the front end of the bottom plate 1203 to facilitate the passing of the welding end of the cable.

[0051] In this embodiment, in order to facilitate the taking of the jig, an extraction mechanism 1400 is also installed at the left end of the panel 1300. The extraction mechanism 1400 includes a support plate connected to the panel 1300, and handles are installed on the left and right sides of the support plate.

[0052] The robot 530 first places the connecting terminal in the positioning groove 1206 to pre-position the connecting terminal, and then puts down the inner cover plate 1201, which presses the middle part of the connecting terminal, and then places the cable in the wire groove 1103 so that the welding end of the cable overlaps with the welding end of the connecting terminal, and then presses the cable by rotating the cover plate 1101, and locks the cover plate 1101 by rotating the locking mechanism, and finally puts down the outer cover plate 1202, which is clamped by the buckle 1208, so as to ensure the reliability of the overlap between the welding end of the cable and the welding end of the connecting terminal.
