Description

Technical Field

[0001] This invention relates to the field of connector pin technology, and in particular to a terminal pin insertion machine. Background Technology

[0002] In the connector manufacturing process, connector terminals need to be inserted into the sockets on the connector's plastic parts. Currently, terminal insertion machines are commonly used to insert the connector terminals into the connector's plastic parts. Existing terminal insertion machines include a feeding mechanism for feeding terminals, a clamping mechanism for holding the terminals discharged from the feeding mechanism, and a pushing mechanism for moving the clamping mechanism toward the connector's plastic parts and inserting the terminals into the sockets on the plastic parts. However, existing terminal insertion machines often lack a positioning mechanism for positioning the terminals, making accurate terminal positioning impossible. When the clamping device holds the terminals, the terminals may tilt, resulting in some terminals not being aligned and successfully inserted into the sockets on the plastic parts. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a terminal pin insertion machine that can position the terminal before the pin is inserted.

[0004] To solve the above-mentioned technical problems, the present invention provides a terminal insertion machine for inserting the insertion end of a terminal into a socket on a plastic part. The machine includes a frame and a feeding device, a support and positioning device, a clamping device, and a push-pull mechanism mounted on the frame. The feeding device has a feeding outlet for discharging terminals one by one. The support and positioning device is located at the feeding outlet and is used to support and position the terminals discharged through the feeding outlet so that the insertion end of the terminal is aligned with the socket on the plastic part. The clamping device is located at the support and positioning device and is used to clamp the terminal after it has been positioned by the support and positioning device. The push-pull mechanism is used to drive the clamping device holding the terminal to move so that the terminal is inserted into the socket on the plastic part. The push-pull mechanism is also used to reset the clamping device.

[0005] Furthermore, the support and positioning device includes a support part and a positioning part that are movably mounted on the frame and located on the upper and lower sides of the feed outlet, respectively; a first drive mechanism for driving the support part to rise to support the terminals discharged from the feed outlet; and a second drive mechanism for driving the positioning part to fall to position the terminals supported on the support part. The first drive mechanism is also used to drive the support part to fall and reset, and the second drive mechanism is also used to drive the positioning part to rise and reset, thereby forming a shuttle space between the support part and the positioning part for the clamping device to shuttle through.

[0006] Furthermore, the terminal includes a busbar and at least two positioning holes that are equally spaced along the length of the busbar and perpendicularly penetrate the busbar; the support includes a support body and recessed grooves formed from the upper side of the support body corresponding to the positions of at least two positioning holes; the positioning part includes a first sliding member that is movably mounted on the frame and a positioning member disposed within the first sliding member; the positioning member includes at least two positioning pins disposed within the first sliding member corresponding to the positions of each of the recessed grooves and with their lower ends protruding from the lower end of the first sliding member, and a tapered segment that gradually narrows downward from the lower end of each of the positioning pins; when the tapered segment passes through the corresponding positioning hole and is accommodated in the corresponding recessed groove, the lower end of the positioning pin is adapted to the corresponding positioning hole.

[0007] Furthermore, the positioning pin is slidably disposed within the first sliding member. The positioning member also includes a limiting member disposed on the positioning pin and used to limit the downward sliding endpoint of the positioning pin, and a counterweight disposed on the upper side of the limiting member and slidably disposed within the first sliding member. The counterweight is used to provide counterweight resistance to the upward sliding of the positioning pin.

[0008] Furthermore, the limiting member is a limiting block disposed on the upper end of the positioning pin; a receiving cavity is formed in the first sliding member, the receiving cavity including a main cavity located at the position of the counterweight and adapted to the counterweight, a pin hole located at the position of each positioning pin and adapted to the positioning pin, and a limiting groove for accommodating the limiting block and having its lower end connected to the pin hole and its upper end connected to the main cavity, the upper end of the pin hole penetrating the limiting groove and the lower end penetrating the lower end surface of the first sliding member; the counterweight is slidably disposed in the main cavity, and the positioning pin is slidably disposed in the pin hole.

[0009] Furthermore, the first sliding member includes a first sliding member body that is movably disposed on the frame and an insert disposed on the first sliding member body at a position corresponding to the support portion for supporting the terminal and having its lower end protruding downward from the first sliding member body. When the lower end of the positioning pin is located in the corresponding positioning hole, the lower end of the insert abuts against the terminal on the support portion.

[0010] Furthermore, the feeding device includes a vibratory feeder for holding and discharging terminals one by one, a guide section for guiding the terminals discharged from the vibratory feeder to the feeding outlet position, and a feeding speed control mechanism provided at the guide section position. The guide section has a guide channel adapted to the terminals, with one end connected to the outlet of the vibratory feeder and the other end being the feeding outlet. The feeding speed control mechanism is used to control the conveying speed of the terminals in the guide channel so that the terminals are intermittently discharged from the feeding outlet.

[0011] Furthermore, the terminal includes a busbar and a plurality of first needle-like members arranged parallel to each other at equal intervals along a long edge of the busbar and perpendicular to the long edge. A strip groove is formed between each pair of adjacent first needle-like members. When the short sides of the busbars of two terminals are directly abutting each other, a strip groove is also formed between two adjacent first needle-like members between the two terminals. The feeding speed control mechanism includes an intermittent drive mechanism mounted on the frame and a gear mounted on the output shaft of the intermittent drive mechanism. One side of the gear passes through the material guide channel and meshes with the strip groove.

[0012] Furthermore, the clamping device includes a guide frame mounted on the frame, an upper clamping part and a lower clamping part slidably mounted on the guide frame, and a clamping drive mechanism for driving the upper clamping part and the lower clamping part to move towards each other to clamp the terminal after it has been positioned by the support and positioning device. The clamping drive mechanism is also used to drive the upper clamping part and the lower clamping part to move away from each other to release the terminal between the upper clamping part and the lower clamping part. The clamping drive mechanism includes a third drive mechanism for driving the upper clamping part to move up and down reciprocally and a fourth drive mechanism for driving the lower clamping part to move up and down reciprocally. The push-pull mechanism is used to push the upper clamping part and the lower clamping part toward the plastic part so that the terminal clamped between the upper clamping part and the lower clamping part is inserted into the insertion hole on the plastic part. The push-pull mechanism is also used to pull the upper clamping part and the lower clamping part away from the plastic part so that the upper clamping part and the lower clamping part are reset.

[0013] Furthermore, the upper clamping part includes a second sliding member that can be slidably mounted on the guide frame and an upper clamping plate that is mounted on the second sliding member and can move toward or away from the plastic part. The third driving mechanism is used to drive the second sliding member to slide up and down reciprocally. The lower clamping part includes a third sliding member that can be slidably mounted on the guide frame and a lower clamping plate that is mounted on the third sliding member and can move toward or away from the plastic part. The fourth driving mechanism is used to drive the third sliding member to slide up and down reciprocally. The push-pull mechanism includes a slide block that is mounted along the moving direction of the upper clamping plate and the lower clamping plate, a slider that is slidably mounted on the slide block, a slide rail that is vertically mounted on the slider, and a fifth driving mechanism for driving the slider to slide toward or away from the plastic part on the slide block. The ends of the upper clamping plate and the lower clamping plate that are away from the plastic part can be slidably connected to the slide rail.

[0014] Due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] When using the terminal insertion machine of the present invention, the feeding device transmits the terminal to the support and positioning device. The support and positioning device supports and positions the terminal so that the insertion end of the terminal is aligned with the insertion hole on the plastic part. The clamping device clamps the terminal after it has been positioned by the support and positioning device. The push-pull mechanism drives the clamping device holding the terminal to move so that the terminal is inserted into the insertion hole on the plastic part. Before inserting the terminal into the insertion hole on the plastic part, the terminal insertion machine of the present invention can position the terminal so that the insertion end of the terminal is aligned with the insertion hole on the plastic part, which can reduce the situation where some terminals cannot be aligned and successfully inserted into the insertion hole on the plastic part due to terminal tilting.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0045] To clearly describe the terminal insertion machine of the present invention, the structure of the terminal is briefly described first:

[0046] like Figure 1As shown, the terminal 1 includes a busbar 11, a plurality of positioning holes 121 arranged at equal intervals along the length of the busbar 11 and perpendicularly penetrating the busbar 11, a plurality of first needle-like members 13 arranged at equal intervals parallel to one long edge of the busbar 11 and perpendicular to the one long edge, and second needle-like members 14 arranged at equal intervals parallel to the other long edge of the busbar 11 and perpendicular to the other long edge. A slot 15 is formed between each pair of adjacent first needle-like members 13. When the short sides of the busbars 11 of the two terminals 1 are directly abutting each other, a slot 15 is also formed between the two adjacent first needle-like members 13 of the two terminals 1 (please refer to...). Figure 2 (As shown).

[0047] like Figure 3 and Figure 4 As shown, an embodiment of the terminal pin insertion machine of the present invention includes a frame 2, a feeding device 3, a support and positioning device 4, a clamping device 5, and a push-pull mechanism 6. The feeding device 3, the support and positioning device 4, the clamping device 5, and the push-pull mechanism 6 are all disposed on the frame 2. The feeding device 3 has a feeding outlet 3a for discharging terminals 1 one by one. The support and positioning device 4 is disposed at the feeding outlet 3a and is used to support and position the terminals 1 discharged through the feeding outlet 3a so that the insertion end (i.e., the first needle-like member 13) of the terminals 1 is aligned with the insertion hole on the plastic part. The clamping device 5 is disposed at the support and positioning device 4 and is used to clamp the terminals 1 after being positioned by the support and positioning device 4. The push-pull mechanism 6 is used to drive the clamping device 5 holding the terminals 1 to move so that the terminals 1 are inserted into the insertion hole on the plastic part. The push-pull mechanism 6 is also used to reset the clamping device 5. The terminal insertion machine of the present invention is used to insert the insertion end of terminal 1 into the socket on a plastic part. It has the advantage of reducing the possibility of some terminals 1 being misaligned and unable to be smoothly inserted into the socket on the plastic part due to tilting. When using the terminal insertion machine of the present invention, the feeding device 3 transmits terminal 1 to the support and positioning device 4. The support and positioning device 4 supports and positions terminal 1 so that the insertion end of terminal 1 is aligned with the socket on the plastic part. The clamping device 5 clamps terminal 1 after it has been positioned by the support and positioning device 4. The push-pull mechanism 6 drives the clamping device 5 holding terminal 1 to move so that terminal 1 is inserted into the socket on the plastic part. Before inserting terminal 1 into the socket on the plastic part, the terminal insertion machine of the present invention can position terminal 1 so that the insertion end of terminal 1 is aligned with the socket on the plastic part.

[0048] The frame 2 includes a first base plate 21, a first top plate 22 disposed above the first base plate 21, a connecting portion 23 disposed between the first base plate 21 and the first top plate 22 and used to connect the first top plate 22 and the first base plate 21, and a vertical plate 24 disposed on the connecting portion 23 and located on one side of the first top plate 22.

[0049] The connecting part 23 includes four side plates connected end to end, which form a square frame. The lower end of the square frame is connected to the first base plate 21, and the upper end of the square frame is connected to the first top plate 22. The vertical plate 24 is disposed on one of the side plates. It is understood that the connecting part 23 is not limited to the structure described above. For example, in some embodiments, the connecting part 23 can also be a rod-shaped support member disposed between the first base plate 21 and the first top plate 22. Of course, the connecting part 23 can also have other structural forms, as long as the connecting part 23 can support the first top plate 22 above the first base plate 21.

[0050] The feeding device 3 includes a vibratory feeder (not shown in the figure), a guide section 31, and a feeding speed control mechanism 32. The vibratory feeder is used to hold and discharge the terminals 1 one by one. The vibratory feeder is a common type of machinery, so its specific structure is not described here. The guide section 31 is located on the vertical plate 24 and is used to guide the terminals 1 discharged from the vibratory feeder to the feeding outlet 3a. The feeding speed control mechanism 32 is located on the vertical plate 24 corresponding to the position of the guide section 31. A guide channel is formed in the guide section 31. The guide channel is adapted to the terminals 1. One end of the guide channel is connected to the outlet of the vibratory feeder, and the other end of the guide channel is the feeding outlet 3a. The feeding speed control mechanism 32 is used to control the conveying speed of the terminals 1 in the guide channel so that the terminals 1 are intermittently discharged from the feeding outlet 3a. The vibratory feeder discharges the terminals 1 one by one into the guide channel. The terminals 1 are arranged closely along the guide channel. The short sides of the busbars 11 of every two adjacent terminals 1 in the guide channel are directly opposite each other. Under the action of the feeding speed control mechanism 32, the terminals 1 are discharged intermittently from the feeding outlet 3a to adapt to the positioning speed of the support positioning device 4 on the terminals 1 and the speed at which the push-pull mechanism 6 pushes the clamping device 5 to insert the terminals 1 into the holes on the plastic parts.

[0051] like Figure 4 and Figure 5As shown, the material guiding part 31 includes a material guiding plate 311 disposed on the vertical plate 24, a groove 312 formed by recessing downward from the upper side of the material guiding plate 311, and a cover plate 313 disposed on the material guiding plate 311. The material guiding plate 311 has a first strip-shaped hole 3111 with one end penetrating through the bottom wall of the groove 312 and the other end penetrating through the bottom wall of the material guiding plate 311. The cover plate 313 covers the groove 312 so that the groove 312 forms the material guiding channel, and the terminal 1 is located in the material guiding channel. At this time, the first needle-like member 13 of the terminal 1, facing away from the busbar 11, abuts against a vertical sidewall of the groove 312, and the second needle-like member 14 of the terminal 1, facing away from the busbar 11, abuts against the opposite vertical sidewall of the groove 312. The lower side of the terminal 1 is supported on the bottom wall of the groove 312, and the cover plate 313 abuts against the upper side of the terminal 1, so that the terminal 1 is confined within the guide channel and will not deviate during the movement of the terminal 1.

[0052] The feeding speed control mechanism 32 includes an intermittent drive mechanism 321 and a gear 322. The intermittent drive mechanism 321 can be a servo motor or a stepper motor. The intermittent drive mechanism 321 is mounted on the frame 2. Specifically, the intermittent drive mechanism 321 is mounted on the vertical plate 24. The gear 322 is mounted on the output shaft of the intermittent drive mechanism 321. One side of the gear 322 passes through the material guide channel and meshes with the strip groove 15. Specifically, a part of the gear 322 passes through the first strip hole 3111 into the groove 312 and meshes with the strip groove 15. As the vibratory feeder discharges the terminals 1 one by one into the feed channel, the terminals 1 are arranged closely along the feed channel. The short sides of the busbars 11 of every two adjacent terminals 1 in the feed channel are directly opposite each other. Multiple terminals 1 are arranged in the feed channel to form multiple strip grooves 15 arranged along the feed channel. The intermittent drive mechanism 321 drives the gear 322 to rotate intermittently. The gear 322 can drive the terminals 1 to be discharged intermittently from the feed outlet 3a one by one, so as to control the discharge speed of the terminals.

[0053] like Figure 6 and Figure 13As shown, the support and positioning device 4 includes a guide seat 41, a support part 42, a positioning part 43, a first drive mechanism 44, and a second drive mechanism 45. The guide seat 41 is disposed on the frame 2, specifically on the first top plate 22. The guide seat 41 is located at the feed outlet 3a. The support part 42 and the positioning part 43 are slidably disposed on the guide seat 41 and are respectively located on the upper and lower sides of the feed outlet 3a. The first drive mechanism 44 is used to drive the support part 42 to rise to support the terminal 1 discharged from the feed outlet 3a. The second drive mechanism 45 is used to drive the positioning part 43 to fall to position the terminal 1 supported on the support part 42. The first drive mechanism 44 is also used to drive the support part 42 to fall and reset. The second drive mechanism 45 is also used to drive the positioning part 43 to rise and reset, thereby forming a shuttle space between the support part 42 and the positioning part 43 for the clamping device 5 to shuttle through. The first driving mechanism 44 drives the support part 42 to rise to the position of the feeding outlet 3a, so that the terminal 1 discharged from the feeding outlet 3a can be pushed onto the support part 42. The second driving mechanism 45 drives the positioning part 43 to descend and position the terminal 1 so that the insertion end of the terminal 1 (i.e., the first needle-like member 13) is aligned with the insertion hole on the plastic part, thereby realizing the positioning of the terminal 1 by the support positioning device 4. After the clamping device 5 clamps the terminal 1 positioned by the positioning part 43, the first driving mechanism 44 drives the support part 42 to descend and reset, and at the same time the second driving mechanism 45 drives the positioning part 43 to rise and reset, in preparation for the support positioning of the next terminal 1. After the support part 42 and the positioning part 43 are both reset, a shuttle space is formed between the support part 42 and the positioning part 43 for the clamping device 5 to shuttle through, so that the clamping device 5 holding the terminal 1 can pass through the shuttle space to insert the insertion end of the terminal 1 into the insertion hole on the plastic part. The guide seat 41 is used to guide the support part 42 and the positioning part 43, so that the support part 42 and the positioning part 43 can move up and down stably and accurately. It can be understood that the guide seat 41 is not a necessary component of the present invention. For example, in some embodiments, the support and positioning device 4 may only include the support part 42, the positioning part 43, the first drive mechanism 44, and the second drive mechanism 45. The first drive mechanism 44 directly drives the support part 42 to rise and fall, and the second drive mechanism 45 directly drives the positioning part 43 to rise and fall.

[0054] The guide seat 41 includes a lower guide block 411 disposed on the first top plate 22, an upper guide block 412 disposed above the lower guide block 411, and two first support rods 413 for connecting the lower guide block 411 and the upper guide block 412. The upper guide block 412 and the lower guide block 411 are respectively disposed on the upper and lower sides of the feeding outlet 3a. The first support rods 413 are not limited to two. In other embodiments, the first support rods 413 can also be other numbers. The clamping device 5 is located between the upper guide block 412 and the lower guide block 411. The lower guide block 411 has a first guide hole 4111 formed at a position corresponding to the support part 42, which is adapted to the support part 42 and extends through its upper and lower end faces. The lower end of the first guide hole 4111 extends to the lower side of the first top plate 22. The support part 42 is slidably disposed within the first guide hole 4111. The upper guide block 412 has a second guide hole 4121 formed at a position corresponding to the positioning part 43, which is adapted to the positioning part 43 and extends through its upper and lower end faces. The positioning part 43 is slidably disposed within the second guide hole 4121. The first guide hole 4111 guides the vertical movement of the support part 42, and the second guide hole 4121 guides the vertical movement of the positioning part 43, thereby enabling the guide seat 41 to guide the support part 42 and the positioning part 43.

[0055] like Figure 6 and Figure 7 As shown, the support part 42 includes a support body 421, a clearance groove 422, and a first transmission groove 423. The upper side of the support body 421 is used to support the terminal 1. There are two clearance grooves 422. The upper side of the support body 421 is recessed inward at the positions corresponding to two of the positioning holes 121 to form clearance grooves 422. The first transmission groove 423 is located at the lower end of the support body 421 and below the first guide hole 4111. It can be understood that in some embodiments, there may be more than two clearance grooves 422.

[0056] like Figure 8As shown, the positioning part 43 includes a first sliding member 431 and a positioning member 432. The first sliding member 431 is movably mounted on the frame 2. In this embodiment, the first sliding member 431 is movably mounted on the frame 2 via the guide seat 41. Specifically, the first sliding member 431 is movably mounted in the second guide hole 4121. The positioning member 432 is located in the first sliding member 431. When the second driving mechanism 45 drives the first sliding member 431 to slide downward in the second guide hole 4121, the first sliding member 431 drives the positioning member 432 to move downward to position the terminal 1 supported on the upper side of the support body 421.

[0057] like Figure 6 and Figure 8 As shown, the first sliding member 431 includes a first sliding member body 4311, an insert 4312, and a second transmission groove 4313. The first sliding member body 4311 is movably mounted on the frame 2. In this embodiment, the first sliding member body 4311 is movably mounted on the frame 2 via the guide seat 41. Specifically, the first sliding member body 4311 is slidably mounted in the second guide hole 4121. The insert 4312 is disposed on the first sliding body 4311 at the position corresponding to the support part 42 for supporting the terminal 1. Specifically, the insert 4312 is disposed on the first sliding body 4311 at the position corresponding to the upper side of the support part body 421 for supporting the terminal 1. The lower end of the insert 4312 protrudes downward from the first sliding body 4311. The second transmission groove 4313 is disposed at the upper end of the first sliding body 4311 and is located above the second guide hole 4121. When the positioning member 432 positions the terminal 1 supported on the upper side of the support part body 421, the lower end of the insert 4312 abuts against the terminal 1 supported on the support part 42 to flatten the terminal 1, preventing the terminal 1 from being unable to be inserted into the hole on the plastic part due to warping and deformation. It can also prevent the terminal 1 from tilting or displacing when the clamping device 5 clamps the terminal 1, ensuring that the terminal 1 clamped by the clamping device 5 is a terminal 1 with accurate angle and position.

[0058] like Figure 9As shown, a receiving cavity 43111 is formed within the first sliding member 431. The receiving cavity 43111 includes a main cavity 43111a, pin holes 43111b, and limiting grooves 43111c. The main cavity 43111a is located within the first sliding member body 4311. There are two pin holes 43111b. In other embodiments, there may be more than two pin holes 43111b. The two pin holes 43111b are located within the insert 4312, corresponding to the positions of the two clearance grooves 422 respectively. There are two limiting grooves 43111c. In other embodiments... In this embodiment, the limiting groove 43111c can be two or more other numbers. The two limiting grooves 43111c are respectively located at the upper ends of the two pin holes 43111b. The lower end of the limiting groove 43111c communicates with the corresponding pin hole 43111b. The upper end of the limiting groove 43111c communicates with the main cavity 43111a. The upper end of the pin hole 43111b passes through the limiting groove 43111c, and the lower end of the pin hole 43111b passes through the lower end face of the first sliding member 431. Specifically, the lower end of the pin hole 43111b passes through the lower end face of the insert 4312. It can be understood that the pin holes 43111b and the limiting grooves 43111c are not limited to the above-described positions. For example, in some embodiments, both the pin holes 43111b and the limiting grooves 43111c can be located within the first sliding member body 4311.

[0059] The positioning component 432 includes a positioning pin 4321, a tapered section 4322, a limiting component 4323, and a counterweight 4324. There are two positioning pins 4321. It can be understood that in some embodiments, there may be more than two positioning pins 4321. The two positioning pins 4321 are disposed in the first sliding component 431, respectively corresponding to the positions of the respective clearance grooves 422. Specifically, the positioning pin 4321 is disposed in the pin hole 43111b and is adapted to the pin hole 43111b so that the positioning pin 4321 can slide up and down in the pin hole 43111b, that is, the positioning pin 4321 can be slidably disposed in the first sliding component 431. The lower end of the positioning pin 4321 protrudes from the lower end of the first sliding member 431. Specifically, the lower end of the positioning pin 4321 protrudes from the lower end of the insert 4312. The tapered segment 4322 gradually narrows downward from the lower end of the positioning pin 4321. When the tapered segment 4322 passes through the corresponding positioning hole 121 and is accommodated in the corresponding clearance groove 422, the lower end of the positioning pin 4321 is adapted to the corresponding positioning hole 121. At this time, the lower end of the insert 4312 abuts against the terminal 1 supported on the support part 42. The limiting member 4323 is disposed on the positioning pin 4321. The limiting member 4323 is used to limit the downward sliding end position of the positioning pin 4321 so that the positioning pin 4321 cannot fall downward from the pin hole 43111b. The counterweight 4324 is disposed on the upper side of the limiting member 4323. The counterweight 4324 is slidably disposed in the first sliding member 431. Specifically, the counterweight 4324 is adapted to the main cavity 43111a. The counterweight 4324 is slidably disposed in the main cavity 43111a. The counterweight 4324 is used to provide counterweight resistance for the upward sliding of the positioning pin 4321. After the first driving mechanism 44 drives the support body 421 to rise and support the terminal 1, the second driving mechanism 45 drives the first sliding body 4311 and the insert 4312 to fall, causing the positioning pin 4321 and the tapered segment 4322 to fall. Each tapered segment 4322 is inserted into the corresponding positioning hole 121. As each tapered segment 4322 continues to fall, under the resistance provided by the counterweight, each tapered segment 4322 contacts the corresponding positioning hole 121 and laterally presses the sidewall of the positioning hole 121 to adjust the position and angle of the terminal 1 until the lower end of each positioning pin 4321 is located in the corresponding positioning hole 121. Since the positioning pin 4321 is adapted to the positioning hole 121, the terminal 1 is adjusted to the accurate position and angle. In this way, the support part 42 and the positioning part 43 can support and position the terminal 1, which is very convenient when supporting and positioning the terminal 1.When the terminal 1 is offset too much on the upper side of the support body 421, causing the positioning hole 121 on the terminal 1 to completely deviate from the lower end of the tapered segment 4322, the lower end of the tapered segment 4322 will face the position on the terminal 1 without the positioning hole 121. After the tapered segment 4322 and the positioning pin 4321 descend a certain distance with the first sliding body 4311 and the insert 4312, the lower end of the tapered segment 4322 will abut against and support the terminal 1. Since the positioning pin 4321 can slide in the pin hole 43111b, as the first sliding body 4311 continues to move downward, the first sliding member 431 cannot continue to drive the positioning pin 4321 and the tapered segment 4322 to continue to move downward, thus preventing the tapered segment 4322 from crushing the terminal 1. It is understood that the positioning element 432 is not limited to the structure described above. For example, in some embodiments, the positioning pin 4321 can be directly connected to the counterweight 4324. In other embodiments, the positioning element 432 may only include the positioning pin 4321, which is fixedly disposed on the insert 4312.

[0060] The limiting member 4323 is a limiting block disposed on the upper end of the positioning pin 4321. The limiting block is accommodated within the limiting groove 43111c and is adapted to the limiting groove 43111c. It can be understood that the limiting part is not limited to the structure described above. For example, in some embodiments, the limiting member 4323 can also be a limiting rod perpendicular to the positioning pin 4321. The two ends of the limiting rod protrude from the two sides of the positioning pin 4321, and the lower side of the limiting rod abuts against the bottom wall of the limiting groove 43111c.

[0061] like Figure 14As shown, the first drive mechanism 44 includes a main shaft 441 rotatably disposed between the first top plate 22 and the first bottom plate 21, a first conjugate cam 442 disposed on the main shaft 441, a first conjugate cam follower 443 rotatably connected to the first top plate 22 and linked with the first conjugate cam 442, a first output arm 444 disposed on the first conjugate cam follower 443 and swinging up and down with the first conjugate cam follower 443, and a first output arm 444 rotatably disposed on the first output arm 44. The first rotating wheel 445 on the main shaft 441 and the power device 446 for driving the main shaft 441 to rotate are provided. The first rotating wheel 445 is located in the first transmission groove 423 and is adapted to the first transmission groove 423. The power device 446 includes a motor 4461, a first pulley 4462 on the output shaft of the motor 4461, a second pulley 4463 on the main shaft 441, and a transmission belt 4464 wound between the first pulley 4462 and the second pulley 4463. The motor 4461 drives the first pulley 4462 to rotate, and the first pulley 4462 drives the second pulley 4463 to rotate via the transmission belt 4464. The main shaft 441 rotates with the second pulley 4463, and the first conjugate cam 442 rotates with the main shaft 441. The first conjugate cam follower 443 is linked with the first conjugate cam 442, and the first conjugate cam follower 443 drives the first output arm 444 to swing up and down, thereby driving the support body 421 to move up and down within the first guide hole 4111. In other words, the first drive mechanism 44 drives the support 42 to rise and fall. With this structure, the first drive mechanism 44 can drive the support 42 to quickly reciprocate up and down. It is understood that the first drive mechanism 44 is not limited to the structure described above. For example, the first drive mechanism 44 can also be a cylinder, hydraulic cylinder or push rod motor whose output shaft is connected to the support body 421. In this case, the guide seat 41 is not required, and the support 42 is directly set on the output shaft of the first drive mechanism 44. The first drive mechanism 44 can then drive the support 42 to move up and down on the frame 2.

[0062] like Figure 15As shown, the second drive mechanism 45 includes a second conjugate cam 451 rotatably mounted on the main shaft 441, a second conjugate cam follower 452 rotatably mounted on the first top plate 22 and linked with the second conjugate cam 451, a second output arm 453 whose first end is connected to the second conjugate cam follower 452 and whose second end swings up and down with the second conjugate cam follower 452, a first connecting rod 454 whose lower end is hinged to the second end of the second output arm 453 and moves up and down with the second end of the second output arm 453, a lever support 455 mounted on the upper guide block 412 and having a lever shaft, a lever 457 rotatably mounted on the lever shaft, and a second rotating wheel 457 rotatably mounted on the resistance arm of the lever 457. The upper end of the first connecting rod 454 passes upward through the first top plate 22 and is hinged to the power arm of the lever 457. The second rotating wheel 457 is located in the second transmission groove 4313 and is adapted to the second transmission groove 4313. The motor 4461 drives the first pulley 4462 to rotate, and the first pulley 4462 drives the second pulley 4463 to rotate via the transmission belt 4464. The main shaft 441 rotates with the second pulley 4463, and the second conjugate cam 451 rotates with the main shaft 441. The second conjugate cam follower 452 is linked with the second conjugate cam 451. The second conjugate cam follower 452 drives the second output arm 453 to swing up and down. The second output arm 453 drives the first connecting rod 454 to move up and down. The first connecting rod 454 drives the power arm of the lever 457 to swing up and down around the lever axis. The resistance arm of the lever 457 also swings up and down around the lever axis, thereby driving the first sliding body 4311 to move up and down within the first guide hole 4111. This achieves the lifting and lowering of the positioning part 43 by the second drive mechanism 45. With this structure, the second drive mechanism 45 can drive the positioning part 43 to quickly reciprocate up and down. It is understood that the second drive mechanism 45 is not limited to the structure described above. For example, in some embodiments, the second drive mechanism 45 can also be a cylinder, hydraulic cylinder, or push rod motor whose output shaft is connected to the first sliding body 4311. In this case, the guide seat 41 is not required, and the support part 42 is directly mounted on the output shaft of the first drive mechanism 44, so that the first drive mechanism 44 can drive the support part 42 to move up and down on the frame 2. In addition, in other embodiments, the lever support 455 can be directly fixed to the first top plate 22.

[0063] like Figure 10 and Figure 13As shown, the clamping device 5 includes a guide frame 51, an upper clamping part 52, a lower clamping part 53, and a clamping drive mechanism 54. The clamping drive mechanism 54 is used to drive the upper clamping part 52 and the lower clamping part 53 to move towards each other to clamp the terminal 1 after it has been positioned by the support and positioning device 4. The clamping drive mechanism 54 is also used to drive the upper clamping part 52 and the lower clamping part 53 to move away from each other to release the terminal 1 between the upper clamping part 52 and the lower clamping part 53. After the support and positioning device 4 completes the support and positioning of the terminal 1, the clamping drive mechanism 54 drives the upper clamping part 52 and the lower clamping part 53 to move towards each other to clamp the terminal 1 after it has been supported and positioned. Then, the push-pull mechanism 6 pushes the upper clamping part 52 and the lower clamping part 53 holding the terminal 1 toward the direction of the plastic part. After the upper clamping part 52 and the lower clamping part 53 pass through the shuttle space, the terminal 1 held between the upper clamping part 52 and the lower clamping part 53 is inserted into the socket on the plastic part. Then, the clamping drive mechanism 54 drives the upper clamping part 52 and the lower clamping part 53 to move apart and release the terminal 1 that has been inserted into the plastic part. Finally, the push-pull mechanism 6 pulls the upper clamping part 52 and the lower clamping part 53 away from the plastic part to move back to their original position, in preparation for clamping the terminal 1 again.

[0064] The guide frame 51 includes a second base plate 511 fixed to the first top plate 22, a second top plate 512 disposed above the second base plate 511, and a second support rod 513 for connecting the second top plate 512 and the second base plate 511. The second base plate 511 has two third guide holes 5111 penetrating its upper and lower sides and used to guide the lifting and lowering of the upper clamping part 52, and two fourth guide holes 5112 penetrating its upper and lower sides and used to guide the lifting and lowering of the lower clamping part 53. The second top plate 512 has two fifth guide holes 5121 penetrating its upper and lower sides and used to guide the lifting and lowering of the upper clamping part 52, and two sixth guide holes 5122 penetrating its upper and lower sides and used to guide the lifting and lowering of the lower clamping part 53. It is understood that in other embodiments, the number of third guide holes 5111, fourth guide holes 5112, fifth guide holes 5121, and sixth guide holes 5122 may be different.

[0065] like Figure 11As shown, the upper clamping part 52 includes a second sliding member 521 and an upper clamping plate 522. The second sliding member 521 is slidably mounted on the guide frame 51. The upper clamping plate 522 is mounted on the second sliding member 521 and can move toward or away from the plastic part. A first slider 5221 is provided at the end of the upper clamping plate 522 away from the plastic part. The second sliding member 521 includes a first connecting block 5211, a first sliding rod 5212, and a first fixing block 5213. The first connecting block 5211 is located below the first top plate 22. A third transmission groove 52111 is formed on the first connecting block 5211. There are two first sliding rods 5212. The lower ends of the sliding rods 5212 pass through the first top plate 22 and connect to the first connecting block 5211. The upper ends of the two first sliding rods 5212 pass through the two third guide holes 5111 and the two fifth guide holes 5121 respectively and are located above the second top plate 512. The first fixing block 5213 is located between the second top plate 512 and the second bottom plate 511 and is fixed to the two first sliding rods 5212. The first fixing block 5213 has a first sliding groove 52131 formed on it, which is arranged along the moving direction of the upper clamping part 52 and is adapted to the upper clamping plate 522. The upper clamping plate 522 is slidably fitted in the first sliding groove 52131. It can be understood that the number of the first sliding rods 5212 is not limited to two. For example, in some embodiments, the number of the first sliding rods 5212 can also be other.

[0066] The lower clamping part 53 includes a third sliding member 531 and a lower clamping plate 532. The third sliding member 531 is slidably mounted on the guide frame 51. The lower clamping plate 532 is mounted on the third sliding member 531 and can move toward or away from the plastic part. A second slider 5321 is provided at the end of the lower clamping plate 532 away from the plastic part. The third sliding member 531 includes a second connecting block 5311, a second sliding rod 5312, and a second fixing block 5313. The second connecting block 5311 is located below the first top plate 22. A fourth transmission groove 53111 is formed on the second connecting block 5311. There are two second sliding rods 5312. The lower ends of the moving rods 5312 pass through the first top plate 22 and connect to the second connecting block 5311. The upper ends of the two second sliding rods 5312 pass through the two fourth guide holes 5112 and the two sixth guide holes 5122 respectively and are located above the second top plate 512. The second fixing block 5313 is located between the second top plate 512 and the second bottom plate 511 and is fixed to the two second sliding rods 5312. The second fixing block 5313 has a second sliding groove 53131 formed on it, which is arranged along the moving direction of the lower clamping part 53 and is adapted to the lower clamping plate 532. The lower clamping plate 532 is slidably fitted in the second sliding groove 53131. It can be understood that the number of the second sliding rods 5312 is not limited to two. For example, in some embodiments, the number of the second sliding rods 5312 can also be other.

[0067] like Figure 13As shown, the clamping drive mechanism 54 includes a third drive mechanism 541 and a fourth drive mechanism 542. The third drive mechanism 541 is used to drive the upper clamping part 52 to move up and down reciprocally. Specifically, the third drive mechanism 541 is used to drive the second sliding member 521 to slide up and down. The fourth drive mechanism 542 is used to drive the lower clamping part 53 to move up and down reciprocally. Specifically, the fourth drive mechanism 542 is used to drive the third sliding member 531 to slide up and down. When the clamping drive mechanism 54 drives the upper clamping part 52 and the lower clamping part 53 to move towards each other to clamp the terminal 1, the third drive mechanism 541 drives the second sliding member 521 to move downward. The second sliding member 521 drives the upper clamping plate 522 to move downward. At the same time, the fourth drive mechanism 542 drives the third sliding member 531 to slide upward. The third sliding member 531 drives the lower clamping plate 532 to move upward. The upper clamping plate 522 and the lower clamping plate 532 can cooperate to clamp the terminal 1, thereby realizing the clamping of the terminal 1 by the upper clamping part 52 and the lower clamping part 53. When the clamping drive mechanism 54 drives the upper clamping part 52 and the lower clamping part 53 to move apart and release terminal 1, the third drive mechanism 541 drives the second sliding member 521 to move upward, and the second sliding member 521 drives the upper clamping plate 522 to move upward. At the same time, the fourth drive mechanism 542 drives the third sliding member 531 to move downward, and the third sliding member 531 drives the lower clamping plate 532 to move downward. The upper clamping plate 522 and the lower clamping plate 532 can then release terminal 1, that is, the upper clamping part 52 and the lower clamping part 53 can then release terminal 1.

[0068] like Figure 16As shown, the third drive mechanism 541 includes a third conjugate cam 5411 rotatably mounted on the main shaft 441, a third conjugate cam follower 5412 rotatably mounted on the first top plate 22 and linked with the third conjugate cam 5411, a third output arm 5413 mounted on the third conjugate cam follower 5412 and swinging up and down with the third conjugate cam follower 5412, and a third rotating wheel 5414 rotatably mounted on the third output arm 5413 at a position corresponding to the third transmission groove 52111. The third rotating wheel 5414 is located in the third transmission groove 52111 and is adapted to the third transmission groove 52111. The motor 4461 drives the first pulley 4462 to rotate, and the first pulley 4462 drives the second pulley 4463 to rotate via the transmission belt 4464. The main shaft 441 rotates with the second pulley 4463, and the third conjugate cam 5411 rotates with the main shaft 441. The third conjugate cam follower 5412 is linked with the third conjugate cam 5411, and the third conjugate cam follower 5412 drives the third output arm 5413 to swing up and down. The third output arm 5413 drives the first connecting block 5211 to move up and down, and the first sliding rod 5212 and the first fixed block 5213 move up and down with the first connecting block 5211, thereby driving the upper clamping plate 522 to move up and down reciprocally. It can be understood that the third drive mechanism 541 is not limited to the structure described above. For example, the third drive mechanism 541 can also be a cylinder, hydraulic cylinder, or push rod motor whose output shaft is connected to the first connecting block 5211.

[0069] The fourth drive mechanism 542 includes a fourth conjugate cam 5421 rotatably mounted on the main shaft 441, a fourth conjugate cam follower 5422 rotatably mounted on the first top plate 22 and linked with the fourth conjugate cam 5421, a fourth output arm 5423 mounted on the fourth conjugate cam follower 5422 and swinging up and down with the fourth conjugate cam follower 5422, and a fourth rotating wheel 5424 rotatably mounted on the fourth output arm 5423 at a position corresponding to the fourth transmission groove 53111. The fourth rotating wheel 5424 is located in the fourth transmission groove 53111 and is adapted to the fourth transmission groove 53111. The motor 4461 drives the first pulley 4462 to rotate, and the first pulley 4462 drives the second pulley 4463 to rotate via the transmission belt 4464. The main shaft 441 rotates with the second pulley 4463, and the fourth conjugate cam 5421 rotates with the main shaft 441. The fourth conjugate cam follower 5422 is linked with the fourth conjugate cam 5421. The fourth conjugate cam follower 5422 drives the fourth output arm 5423 to swing up and down, and the fourth output arm 5423 drives the second connecting block 5311 to move up and down. The second sliding rod 5312 and the second fixed block 5313 move up and down with the second connecting block 5311, thereby driving the upper clamping plate 522 to move up and down reciprocally. It can be understood that the fourth drive mechanism 542 is not limited to the structure described above. For example, the fourth drive mechanism 542 can also be a cylinder, hydraulic cylinder, or push rod motor whose output shaft is connected to the second connecting block 5311.

[0070] The push-pull mechanism 6 is used to push the upper clamp 52 and the lower clamp 53 toward the plastic part so that the terminal 1 clamped between the upper clamp 52 and the lower clamp 53 is inserted into the socket on the plastic part. The push-pull mechanism 6 is also used to pull the upper clamp 52 and the lower clamp 53 away from the plastic part so that the upper clamp 52 and the lower clamp 53 are reset.

[0071] like Figure 12 and Figure 13As shown, the push-pull mechanism 6 includes a slide block 61, a third slider 62, a slide rail 63, and a fifth drive mechanism 64. The slide block 61 is arranged along the moving direction of the upper clamping plate 522 and the lower clamping plate 532, that is, the slide block 61 is arranged in the direction towards and away from the plastic part. The third slider 62 is slidably arranged on the slide block 61. The slide rail 63 is arranged vertically on the third slider 62. The fifth drive mechanism 64 is used to drive the third slider 62 to slide on the slide block 61 towards or away from the plastic part. The first slider 5221 and the second slider 5321 are both slidably engaged on the slide rail 63, so that the upper clamping plate 522 and the lower clamping plate 532 can be slidably connected to the slide rail 63. With this structure, without affecting the up-and-down reciprocating movement of the upper clamping plate 522 and the lower clamping plate 532, the fifth drive mechanism 64 can also drive the third slider 62 to reciprocate toward or away from the plastic part within the slide block 61. The slide rail 63 can reciprocate toward or away from the plastic part along with the third slider 62, thereby driving the upper clamping plate 522 and the lower clamping plate 532 to reciprocate toward or away from the plastic part.

[0072] The slide block 61 includes a seat body 611, a third sliding groove 612 formed by a downward indentation from the upper side of the seat body 611, and a second strip hole 613 that is perpendicular to the bottom wall of the third sliding groove 612 and is arranged along the sliding direction of the third slider 62. The third slider 62 has a receiving groove 621 that is perpendicular to its upper and lower sides at the position corresponding to the second strip hole 613. A fifth rotating wheel 622 is rotatably arranged in the receiving groove 621, and the axis of rotation of the fifth rotating wheel 622 is perpendicular to the sliding direction of the slider.
