Description

Technical Field

[0001] This invention relates to the field of connector processing equipment technology, and in particular to an automatic terminal pin insertion device and its manufacturing process. Background Technology

[0002] The traditional method of inserting terminal pins is to manually insert each pin individually, that is, to insert the pin strip into the terminal and then remove the material strip from the pin strip.

[0003] Currently, manual pin insertion of terminals is prone to errors and inefficient. Utility model patent application CN202220159052.3 discloses an automatic terminal pin insertion machine. A feeding device arranges the terminals in a specific orientation, then a transmission device clamps the terminals in this orientation onto a transmission platform and moves them to the pin insertion device for processing. Finally, a discharging device removes the processed terminals from the transmission platform. When pin insertion is needed, a pin conveyor mechanism transports the pin tape to the pin tape cavity, at which point the grippers... The cylinder drives the gripper block to move closer to the vertical block, thus clamping the needle strip in the needle strip cavity. This clamps the needle strips on both sides of the vertical block. Then, the vertical cylinder drives the vertical seat and moves the vertical block downwards, inserting the needle strip into the terminal. The gripper cylinder then drives the gripper away from the vertical block, leaving the needle strip in the terminal. At this point, the vertical seat is driven upwards. The vertical block is designed with gripper blocks on both sides, ensuring that the needle strip can be clamped from both sides. This allows for the insertion of two rows of needle strips into the terminal at once, greatly improving the efficiency of needle insertion without significantly affecting the size of the insertion device. However, this automatic terminal insertion machine can only operate in a single thread and cannot control the quality of the needle strip. Therefore, there is still room for improvement in its production efficiency and product quality. Thus, it is essential to develop an automatic terminal insertion device and its production process with high production efficiency and high yield. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic terminal pin insertion device and its production process. This invention can automatically perform pin insertion on terminals, which not only has high production efficiency, but also significantly improves the product qualification rate, bringing good economic benefits to enterprises.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic terminal insertion device, comprising multiple sequentially connected transmission platforms for transmitting terminals, wherein multiple main channels are arranged side by side on the transmission platforms, each transmission platform has a claw assembly on one side for moving the terminal along the transmission platform, and each transmission platform has multiple double-sided insertion devices on the other side, and each double-sided insertion device is connected to a slitting module for dividing the insertion strip into two parts and conveying it to the double-sided insertion device for insertion.

[0006] By adopting the above technical solution, terminals are transported by multiple transmission platforms. On each transmission platform, multiple double-sided pin insertion devices perform the pin insertion process on the terminals. After the terminals have passed through multiple transmission platforms, the pin insertion process is completed, which can realize uninterrupted pin insertion of multiple sets of terminals, greatly improving production efficiency. At the same time, the pin insertion material strip of the modified equipment is split in two during on-site feeding, avoiding damage to the pin insertion material strip, thereby significantly improving the product qualification rate and bringing good economic benefits to enterprises.

[0007] The present invention is further configured such that the slitting module includes a frame, on which a take-up reel for taking up the insert strip is rotatably mounted; it also includes a cutting mechanism disposed on the frame and a material-pulling assembly for pulling the insert strip. The cutting mechanism includes a lifting assembly, a lower die base and an upper die base. The lower die base is mounted on the frame. The lifting assembly is connected to the lower die base and is used to drive the lower die base to move vertically toward or away from the lower die base. The upper die base has a plurality of cutting blades for cutting the insert strip installed at one end near the lower die base. The lower die base has a plurality of clearance holes corresponding to the cutting blades. The frame has a feeding port located below the clearance holes.

[0008] By adopting the above technical solution, when the pin insertion strip passes through the cutting mechanism, the lifting component of the cutting mechanism drives the upper mold base to move downward. The cutting blade on the upper mold base splits the pin insertion strip in two. The subsequent pin insertion strip is directly transported to the double-sided pin insertion device for the pin insertion process. This cutting device not only has high processing efficiency, but also cuts the pin insertion strip on the processing site, which can greatly avoid damage to the pin insertion strip due to transportation and winding processes, thereby effectively ensuring the quality of the pin insertion and reducing waste and the number of defective products.

[0009] The present invention is further configured such that the double-sided pin insertion device includes a pin insertion mechanism and a pin strip feeding mechanism connected to the pin insertion mechanism. The pin strip feeding mechanism includes a base plate; it also includes a pin guide rail, a drive component, a pawl, a pawl support, and a brake assembly disposed on the base plate. The end of the pin guide rail is connected to the pin insertion mechanism. The pin guide rail is provided with a pin flow channel for the pin strip to pass through. The output end of the drive component is linked to the pawl support for driving the pawl support to translate in the extension direction of the pin guide rail. The middle part of the pawl is hinged to the pawl support. The side of the pin guide rail has a first opening communicating with the pin flow channel. The pawl support is provided with a first elastic element acting on one end of the pawl, so that the other end of the pawl passes through the first opening and engages with the positioning hole on the pin strip disposed in the pin flow channel, while the pawl and the pawl support are pressed together. The brake assembly is installed on the pin guide rail to prevent the pin strip from regressing.

[0010] By adopting the above technical solution, when the pin insert strip is fed, the drive component pushes out the pawl support. Since one end of the pawl on the pawl support is pressed into the positioning hole of the pin insert strip by a spring, and the pawl support provides an angular limit to the pawl, the pawl drives the pin insert strip to move, advancing it a set distance for the pin insertion mechanism to perform a specific number of pin insertion operations. When the drive component retracts the pawl support, the pawl overcomes the elastic force of the first elastic element and rotates a certain angle, sliding along the surface of the pin insert strip. The pin insert strip will not retract under the action of the braking component. When the drive component returns the pawl support to its initial position, the pawl on the pawl support re-inserts into the positioning hole of the pin insert strip under the action of the first elastic element, starting a new cycle. Therefore, using this device, the advance distance of the pin insert strip can be precisely controlled each time, thereby effectively controlling the number of pins inserted by the pin insertion mechanism in a single operation, ensuring accurate matching between subsequent pins and terminals, and significantly reducing the number of defective products and the waste of raw materials.

[0011] The present invention is further configured such that the brake assembly includes a brake block, the side of the needle guide rail has a second opening communicating with the needle flow channel, the middle part of the brake block is hinged to the needle guide rail, and the needle guide rail is provided with a second elastic member acting on one end of the brake block, so that the other end of the brake block passes through the second opening and abuts against the needle strip disposed in the needle flow channel, while the brake block abuts against the needle guide rail.

[0012] By adopting the above technical solution, when the brake block is pressed against the needle guide rail and the needle strip by the second elastic element, the brake block can no longer rotate towards the direction of the needle guide rail, so that the needle strip cannot drive the brake block to rotate through friction, thereby achieving the effect of preventing the needle strip from backing up.

[0013] The present invention is further configured such that the claw assembly includes a feeding electric slide, a movable frame is mounted on the movable end of the feeding electric slide, a longitudinal cylinder is provided on the movable frame, a longitudinal slide plate is connected to the extended end of the longitudinal cylinder, a transverse cylinder is mounted on the longitudinal slide plate, a transverse slide plate is connected to the extended end of the transverse cylinder, and a plurality of levers for pushing the terminal to move are evenly arranged in the transverse direction on the transverse slide plate.

[0014] By adopting the above technical solution, the cooperation of the horizontal cylinder and the vertical cylinder on the claw assembly drives the lever to perform a forward-right-backward-left cyclic action, realizing the stepping action of the terminal on the transmission platform and ensuring that the terminal can accurately reach the specific work position.

[0015] The present invention is further configured such that the side of the transmission platform is provided with a waste strip removal mechanism, the waste strip removal mechanism including a moving rail, a pushing component, a tilting table, a tensioning component, a tilting component, and a cutting component. The moving rail is slidably disposed on the tilting table, and the moving rail is provided with multiple flow channels corresponding to the main flow channel. The pushing component is installed below the transmission platform to drive the moving rail to move toward or away from the transmission platform. The tensioning component is used to clamp or loosen the terminals on the moving rail. The tilting component is linked to the tilting table to drive the tilting table to rotate, causing the moving rail to move above the cutting component and cut off the pin waste strip.

[0016] By adopting the above technical solution, after the terminal with the inserted pin is conveyed onto the moving rail, the moving rail is pushed out by the pushing component, so that the terminal on the moving rail is completely moved to the flipping table. The flipping component rotates the flipping table, so that the terminal is moved above the cutting component. The tensioning component clamps the terminal, and the cutting component is activated to cut off the pin waste strip on the terminal. After the waste strip on the pin is cut off, the flipping component reverses the flipping table to release the tensioning component from the terminal. Finally, the pushing component pulls the moving rail back to the initial position, thereby quickly removing the waste strip from the pin after it is inserted into the terminal. This not only has high work efficiency, but also only requires one person to operate and monitor, which greatly reduces production costs.

[0017] The present invention is further configured such that the pushing component includes a pushing cylinder and a pushing block, the extended end of the pushing cylinder is linked to the pushing block, and the bottom of the moving rail is provided with a slot for the upper end of the pushing block to be inserted.

[0018] The tensioning assembly includes a clamping cylinder, a releasing cylinder, a traction plate, a positioning block, a moving plate, and a stationary plate. The moving plate and the stationary plate are respectively positioned on both sides of the moving rail on the tilting table. The traction plate is slidably mounted on the tilting table. The positioning block is mounted on the traction plate. The moving plate is mounted on the positioning block. The clamping cylinder is located below the tilting table. When the extended end of the clamping cylinder extends, it acts on the traction plate, causing the traction plate to move the moving plate away from the stationary plate via the positioning block. The releasing cylinder is located between the tilting assembly and the cutting assembly to push the traction plate, causing the traction plate to move the moving plate closer to the stationary plate via the positioning block.

[0019] The flipping assembly includes a flipping seat, a guide seat, a flipping cylinder, a rack, a gear, and a rotating shaft. A guide bar is slidably arranged vertically on the guide seat. The lower end of the guide bar is connected to the extended end of the flipping cylinder. The rack is mounted on the guide bar. The rotating shaft is rotatably mounted on the flipping seat. The flipping platform is sleeved on the outer circumference of the rotating shaft and is keyed to the rotating shaft. The gear is mounted on one end of the rotating shaft and meshes with the rack.

[0020] The cutting assembly includes a cutting support, a cutting cylinder, a knife holder, and a cutting tool. The cutting cylinder is mounted on the cutting support, and the extended end of the cutting cylinder is linked to the knife holder. The cutting tool is mounted on the knife holder.

[0021] By adopting the above technical solution, it is possible to quickly switch the pin terminals at various workstations, with a stable and reliable structure and rapid operation.

[0022] The invention is further configured such that each transmission platform is provided with a terminal feeding mechanism at its front end. The terminal feeding mechanism includes a linear vibration conveying component and a misaligned feeding component. The linear vibration conveying component includes a linear vibrator and a linear vibration track disposed on the linear vibrator. The linear vibration track is misaligned with the corresponding transmission platform. The linear vibration track is provided with multiple linear vibration grooves for transmitting terminals. A cutting cylinder is provided on the linear vibration track. A fixing block is provided on the extended end of the cutting cylinder. Multiple cutting blocks corresponding to the linear vibration grooves are connected to the fixing block. The terminal feeding mechanism includes a misalignment seat. A misalignment electric slide is provided on the misalignment seat. A positioning plate is provided on the moving end of the misalignment electric slide. A misalignment carrier is installed on the positioning plate. The misalignment carrier is disposed between the corresponding linear vibration track and the transmission platform. The misalignment carrier is provided with multiple misalignment grooves for transmitting terminals. A misalignment cylinder is also provided on the positioning plate. A carrier pressure bar disposed above the misalignment carrier is connected to the extended end of the misalignment cylinder.

[0023] By adopting the above technical solution, it is possible to achieve orderly feeding of rows of terminals, thereby enabling the orderly insertion process of the terminals.

[0024] The invention is further configured such that the front transmission platform and the rear linear vibration track are misaligned, and a misaligned transport component is provided between the front transmission platform and the rear linear vibration track. The misaligned transport component includes a transport electric slide, a rear carrier is provided on the moving end of the transport electric slide, a plurality of transport slots for transporting terminals are provided on the rear carrier, and a stand is also provided on the side of the transport electric slide. A transport cylinder is installed on the stand, and a feeding claw is connected to the extended end of the transport cylinder for moving the terminals in the transport slots of the rear carrier to the linear vibration slots of the rear linear vibration track.

[0025] By adopting the above technical solution, the terminals on the previous transmission platform can be transported to the next transmission platform in an orderly manner for orderly insertion of the terminals.

[0026] The present invention also provides a manufacturing process for an automatic terminal pin insertion device, comprising the following steps:

[0027] a. Terminal feeding: The terminals are fed by the linear vibrating conveyor component of the terminal feeding mechanism, and then the staggered feeding component of the terminal feeding mechanism moves the rows of terminals to the front end of the transmission platform. The linear vibrating conveyor component drives the linear track to vibrate through a linear vibrator, thereby moving the terminals on the linear track. When the terminals are conveyed to the staggered carrier of the staggered feeding component, the staggered electric slide pushes the positioning plate to move horizontally. The positioning plate drives the staggered carrier to move horizontally to the front end of the transmission platform and connect with the transmission platform.

[0028] b. Terminal transportation: The terminals in rows on the misaligned carrier are moved to the transmission platform by the lever of the claw assembly. The lever is driven to perform a forward-right-backward-left cycle by the cooperation of the horizontal and vertical cylinders on the claw assembly, so as to realize the stepping action of the terminals on the transmission platform.

[0029] c. Feeding of pin strip: The pin strip on the take-up reel is pulled out by the feeding assembly, and during the pulling out of the pin strip, the cutting mechanism drives the cutting knife to split the pin strip in two.

[0030] d. Terminal pins: Multiple double-sided pin insertion devices perform the pin insertion process simultaneously. The pin strip feeding mechanism in the double-sided pin insertion device transports two separated pin strips to the pin insertion mechanism, and the pin insertion mechanism inserts the pin strips into the corresponding terminals on the transmission platform.

[0031] e. Waste strip removal: The terminal with the pin is conveyed to the moving rail of the waste strip removal mechanism by the lever of the claw assembly. The moving rail is pushed out by the push assembly, so that the terminal on the moving rail is completely moved to the flipping table. The flipping assembly rotates the flipping table, so that the terminal is moved above the cutting assembly. The terminal is clamped by the tensioning assembly. The cutting assembly is started to cut off the waste strip of the pin on the terminal. After the waste strip on the pin is cut off, the flipping assembly reverses the flipping table to release the tensioning assembly from the terminal. Finally, the moving rail is pulled back to the initial position by the push assembly.

[0032] f. Circulating pin insertion: The terminal with pins is pushed to the rear carrier of the misaligned transport component by the lever of the claw assembly. Then, the rear carrier is pushed to the side of the terminal feeding mechanism of the next transmission platform by the transport cylinder on the misaligned transport component. The transport cylinder on the misaligned transport component drives the claw to move the terminal in the transport groove of the rear carrier to the straight vibration groove of the rear straight vibration track. This is done in a circulating manner until the terminal is full of pins.

[0033] By adopting the above technical solution, the present invention can automatically perform pin insertion on terminals, and perform the pin insertion process simultaneously in multiple channels and multiple stations. This not only has high production efficiency, but also protects the pin strip, thereby significantly improving the product qualification rate and bringing good economic benefits to enterprises.

Detailed Implementation

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Example: As attached Figures 1-20 The automatic terminal insertion device shown includes multiple sequentially connected transmission platforms 1 for transporting terminals. Multiple main channels 2 are arranged side-by-side on each transmission platform 1. Each transmission platform 1 has a claw assembly 3 on one side for guiding the terminals along the transmission platform 1. Each transmission platform 1 has multiple double-sided insertion devices 4 on the other side, and each double-sided insertion device 4 is connected to a slitting module 5 for splitting the insertion strip 36 in half and conveying it to the double-sided insertion device 4 for insertion. Terminals are transported via multiple transmission platforms 1, and on each transmission platform 1, the terminals are inserted by multiple double-sided insertion devices 4. After the terminals have passed through multiple transmission platforms 1, the insertion process is completed, enabling uninterrupted insertion of multiple sets of terminals, greatly improving production efficiency. Furthermore, the insertion strip 36 of this device is split in half during on-site feeding, avoiding damage to the insertion strip 36, thereby significantly improving the product qualification rate and bringing good economic benefits to the enterprise.

[0057] As attached Figures 2-8As shown, the slitting module 5 includes a frame 6, on which a take-up reel 7 for winding the pin insert strip 36 is rotatably mounted. The pin insert strip 36 initially consists of two symmetrical strips connected together by multiple connecting strips 37. It also includes a cutting mechanism 8 mounted on the frame 6 and a material-pulling assembly 9 for pulling the pin insert strip 36. The cutting mechanism 8 includes a lifting assembly 10, a lower die base 11, and an upper die base 12. The lower die base 11 is mounted on the frame 6. The lifting assembly 10 is connected to the lower mold base 11 and is used to drive the lower mold base 11 to move vertically toward or away from the lower mold base 11. The upper mold base 12 is equipped with a plurality of cutting blades 13 for cutting the insert strip 36 at one end near the lower mold base 11. The strip breaks the connecting strip 37 on the strip, thus splitting the strip in two. The lower mold base 11 is provided with a plurality of clearance holes 14 corresponding to the cutting blades 13. The frame 6 is provided with a discharge port 15 at the position below the clearance holes 14. When the pin insertion strip 36 passes through the cutting mechanism 8, the lifting component 10 of the cutting mechanism 8 drives the upper mold base 12 to move downward. The cutting blade 13 on the upper mold base 12 cuts the pin insertion strip 36 into two parts. The subsequent pin insertion strip 36 is directly transported to the double-sided pin insertion device 4 for the pin insertion process. This cutting device not only has high processing efficiency, but also cuts the pin insertion strip 36 on the processing site, which can greatly avoid damage to the pin insertion strip 36 due to transportation and winding processes, thereby effectively ensuring the quality of the pin insertion and reducing waste and the number of defective products.

[0058] The lower mold base 11 includes a base 16 and a template 17. The base 16 has a lower mounting groove 18. The inner end of the lower mounting groove 18 has a lower opening 19 that communicates with the material discharge port 15. The template 17 is detachably installed in the lower mounting groove 18 by screws. The shape of the lower mounting groove 18 corresponds to the template 17. The clearance hole 14 is opened on the template 17.

[0059] The positioning pin and the cutting tool 13 both penetrate the upper mold base 12, and the upper ends of the positioning pin and the cutting tool 13 are respectively provided with a first limiting flange 20 and a second limiting flange. The upper mold base 12 is detachably mounted with a pressure plate 21 for pressing the first limiting flange 20 and the second limiting flange onto the upper end of the upper mold base 12 by screws.

[0060] The lower mold base 11 is equipped with multiple guide posts, and the upper mold base 12 is provided with multiple guide holes that cooperate with the guide posts.

[0061] The lifting assembly 10 includes a support 22, a first drive motor 23, and an eccentric shaft 24. The first drive motor 23 is mounted on the support 22, and the support 22 is provided with a first bearing seat 25. The eccentric shaft 24 is rotatably mounted on the first bearing seat 25. The motor shaft of the first drive motor 23 is linked to the eccentric shaft 24. A transmission shaft 30 bearing 26 is mounted on the end of the eccentric shaft 24 away from the first drive motor 23. The upper mold base 12 is provided with a transmission seat 27, and the transmission seat 27 is provided with an elongated oval hole 28 that cooperates with the transmission shaft 30 bearing 26. The eccentric shaft 24 includes a main shaft part and an eccentric wheel part. The main shaft part is coaxial with the motor shaft of the first drive motor 23, and the eccentric wheel part is not coaxial with the main shaft part. The transmission shaft 30 bearing 26 is snapped onto the eccentric shaft 24 part by a snap ring.

[0062] The feeding assembly 9 includes a second drive motor 29, a transmission shaft 30, and two feeding wheels 31. The insert strip 36 has feeding holes 38. The frame 6 is provided with a feeding track 32. A second bearing seat 33 is provided on each side of the feeding track 32. The transmission shaft 30 is rotatably mounted on the two second bearing seats 33, and one end of the transmission shaft 30 is linked to the motor shaft of the second drive motor 29. The two feeding wheels 31 are linkedly mounted on the transmission shaft 30. The feeding wheels 31 are provided with feeding teeth 34 corresponding to the feeding holes 38. The feeding track 32 is provided with two clearance grooves 35 below the feeding holes 38 of the strip for the feeding teeth 34 of the corresponding feeding wheels 31 to extend into.

[0063] As attached Figures 9-12As shown, the double-sided pin insertion device 4 includes a pin insertion mechanism 39 (the pin insertion mechanism 39 adopts the pin insertion device in an automatic terminal pin insertion machine disclosed in utility model patent application number CN202220159052.3) and a pin strip feeding mechanism 40 connected to the pin insertion mechanism 39. The pin strip feeding mechanism 40 includes a base plate 41; it also includes a pin guide rail 42, a driving component 43 (cylinder), a pawl 44, a pawl support 45, and a brake assembly 46 disposed on the base plate 41. The end of the pin guide rail 42 is connected to the pin insertion mechanism 39. The pin guide rail 42 is provided with a pin flow channel 47 for the pin strip 36 to pass through. The driving component... The output end of drive component 43 is linked to pawl support 45 to drive pawl support 45 to translate in the extension direction of needle guide rail 42. Pawl 44 is hinged to pawl support 45 in the middle. The side of needle guide rail 42 has a first opening 48 that communicates with needle flow channel 47. Pawl support 45 has a first elastic element 49 acting on one end of pawl 44, so that the other end of pawl 44 passes through the first opening 48 and engages with the positioning hole on needle strip 36 in needle flow channel 47. At the same time, pawl 44 and pawl support 45 are pressed together. Brake assembly 46 is installed on needle guide rail 42 to prevent needle strip 36 from regressing. There are two sets of drive component 43, pawl 44, pawl support 45, first elastic element 49 (spring) and brake assembly 46, which are symmetrically arranged on both sides of needle guide rail 42. When the pin insert strip 36 is fed, the drive member 43 drives the pawl support 45 to push it out. Since one end of the pawl 44 on the pawl support 45 is pressed into the positioning hole of the pin insert strip 36 by the spring, and the pawl support 45 limits the angle of the pawl 44, the pawl 44 drives the pin insert strip 36 to move, so that the pin insert strip 36 advances a set distance, and a specific number of pins are inserted in the pin insertion mechanism 39. When the drive member 43 drives the pawl support 45 to retract, the pawl 44 overcomes the elastic force of the first elastic member 49 and rotates a certain angle, and slides along the surface of the pin insert strip 36. The pin insert strip 36 will not retract under the action of the brake assembly 46. When the drive member 43 drives the pawl support 45 back to the initial position, the pawl 44 on the pawl support 45 is re-inserted into the positioning hole of the pin insert strip 36 under the action of the first elastic member 49, and a new cycle begins. Therefore, by using this device, the advance distance of the pin insert strip 36 can be precisely controlled each time, thereby effectively controlling the number of pins inserted by the pin insert mechanism 39 in a single operation, so as to ensure the precise matching of subsequent pins and terminals, and significantly reduce the number of defective products and the waste of raw materials.

[0064] The brake assembly 46 includes a brake block 50. The side of the pin guide rail 42 has a second opening 51 communicating with the pin flow channel 47. The middle of the brake block 50 is hinged to the pin guide rail 42. The pin guide rail 42 has a second elastic element 52 (spring) acting on one end of the brake block 50, so that the other end of the brake block 50 passes through the second opening 51 and abuts against the pin material strip 36 disposed in the pin flow channel 47, while the brake block 50 abuts against the pin guide rail 42. When the brake block 50 is pressed against the pin guide rail 42 and the pin material strip 36 by the second elastic element 52, the brake block 50 can no longer rotate towards the pin guide rail 42, thus preventing the pin material strip 36 from driving the brake block 50 to rotate through friction, thereby achieving the effect of preventing the pin material strip 36 from backing up.

[0065] The device also includes a material guide groove 53 located on the base plate 41 in front of the pin guide rail 42. At least two limiting rods 54 are arranged side by side on the material guide groove 53. A limiting channel 55 for the pin material strip 36 to pass through is formed between two adjacent limiting rods 54. The specific number of limiting rods 54 is three, and the three limiting rods 54 form two limiting channels 55.

[0066] As attached Figure 13 As shown, the claw assembly 3 includes a feeding electric slide 56. A moving frame 57 is mounted on the moving end of the feeding electric slide 56. A longitudinal cylinder 58 is provided on the moving frame 57. A longitudinal slide plate 59 is connected to the extended end of the longitudinal cylinder 58. A transverse cylinder 60 is mounted on the longitudinal slide plate 59. A transverse slide plate 61 is connected to the extended end of the transverse cylinder 60. Multiple levers 62 for pushing the terminals to move are evenly arranged laterally on the transverse slide plate 61. The cooperation between the transverse cylinder 60 and the longitudinal cylinder 58 on the claw assembly 3 drives the levers 62 to perform a forward-right-backward-left cyclic action, realizing the stepping action of the terminal on the transmission platform 1, ensuring that the terminal can accurately reach the specific work position.

[0067] As attached Figures 14-18As shown, the side of the transmission platform 1 is also provided with a waste strip removal mechanism 63. The waste strip removal mechanism 63 includes a moving rail 64, a pushing component 65, a tilting table 66, a tensioning component 67, a tilting component 68, and a cutting component 69. The moving rail 64 is slidably disposed on the tilting table 66. The moving rail 64 is provided with multiple flow channels 70 corresponding to the main flow channel 2. The pushing component 65 is installed below the transmission platform 1 to drive the moving rail 64 to move toward or away from the transmission platform 1. The tensioning component 67 is used to clamp or loosen the terminals on the moving rail 64. The tilting component 68 is linked to the tilting table 66 to drive the tilting table 66 to rotate, causing the moving rail 64 to move above the cutting component 69 and cut off the pin waste strip. After the terminal with the inserted pin is conveyed onto the moving rail 64, the moving rail 64 is pushed out by the pushing component 65, so that the terminal on the moving rail 64 is completely moved onto the flipping table 66. The flipping component 68 rotates the flipping table 66, so that the terminal is moved above the cutting component 69. The terminal is clamped by the tensioning component 67. The cutting component 69 is activated to cut off the pin waste strip on the terminal. After the waste strip on the pin is cut off, the flipping component 68 reverses the flipping table 66 to release the tensioning component 67 from the terminal. Finally, the moving rail 64 is pulled back to the initial position by the pushing component 65. Thus, the waste strip of the pin is quickly removed after the pin is inserted into the terminal. It is not only highly efficient, but also only requires one person to operate and monitor, which greatly reduces production costs.

[0068] The pushing component 65 includes a pushing cylinder 71 and a pushing block 72. The extended end of the pushing cylinder 71 is linked to the pushing block 72. The bottom of the moving rail 64 is provided with a slot 73 for the upper end of the pushing block 72 to be inserted.

[0069] The tensioning assembly 67 includes a clamping cylinder 74, a releasing cylinder 75, a traction plate 76, a positioning block 77, a moving plate 78, and a stationary plate 79.

The traction plate 76 is slidably mounted on the tilting table 66. The positioning block 77 is mounted on the traction plate 76, and the moving plate 78 is mounted on the positioning block 77. The clamping cylinder 74 is located below the tilting table 66. When the extended end of the clamping cylinder 74 extends, it acts on the traction plate 76, causing the traction plate... 76 drives the moving plate 78 to move away from the stationary plate 79 via the positioning block 77. The loosening cylinder 75 is located between the flipping assembly 68 and the cutting assembly 69 to push the traction plate 76, so that the traction plate 76 drives the moving plate 78 to move closer to the stationary plate 79 via the positioning block 77. The moving plate 78 is connected to the positioning block 77 by screws. The positioning block 77 is provided with a guide protrusion. The moving plate 78 is provided with a strip-shaped guide hole that cooperates with the guide protrusion. The moving plate 78 is provided with a strip-shaped clearance hole on each side of the strip-shaped guide hole for the screw to pass through.

[0070] The flipping assembly 68 includes a flipping seat 80, a guide seat 81, a flipping cylinder 82, a rack 83, a gear 84, and a rotating shaft 85. A guide bar 86 is slidably disposed on the guide seat 81 along the vertical direction. The lower end of the guide bar 86 is connected to the extended end of the flipping cylinder 82. The rack 83 is mounted on the guide bar 86. The rotating shaft 85 is rotatably mounted on the flipping seat 80. The flipping platform 66 is sleeved on the outer periphery of the rotating shaft 85 and is keyed to the rotating shaft 85. The gear 84 is mounted on one end of the rotating shaft 85 and meshes with the rack 83.

[0071] The cutting assembly 69 includes a cutting support 87, a cutting cylinder 88, a knife holder 89, and a cutting tool 90. The cutting cylinder 88 is mounted on the cutting support 87, and the extended end of the cutting cylinder 88 is linked to the knife holder 89. The cutting tool 90 is mounted on the knife holder 89.

[0072] This design enables rapid switching of pin terminals at various workstations, with a stable and reliable structure and fast operation.

The terminal feeding mechanism 91 includes a linear vibration conveying component 92 and a staggered feeding component 93. The linear vibration conveying component 92 includes a linear vibrator 94 and a linear vibration track 95 disposed on the linear vibrator 94. The linear vibration track 95 is staggered with the corresponding transmission platform 1. The linear vibration track 95 is provided with multiple linear vibration grooves 96 for transmitting terminals. The linear vibration track 95 is provided with a cut-off cylinder 97. The extended end of the cut-off cylinder 97 is provided with a fixing block 98. Multiple objects opposite to the linear vibration grooves 96 are connected to the fixing block 98. The terminal feeding mechanism 91 includes a misalignment seat 100, on which a misalignment electric slide 101 is provided. A positioning plate 102 is provided on the moving end of the misalignment electric slide 101. A misalignment carrier 103 is mounted on the positioning plate 102. The misalignment carrier 103 is positioned between the corresponding linear vibration track 95 and the transmission platform 1. The misalignment carrier 103 has multiple misalignment slots 104 for transmitting terminals. A misalignment cylinder 105 is also provided on the positioning plate 102. A carrier pressure bar 106 is connected to the extended end of the misalignment cylinder 105 and positioned above the misalignment carrier 103. This design enables the orderly feeding of rows of terminals, thereby facilitating the orderly insertion process of the terminals.

[0074] As attached Figure 20 As shown, the front transmission platform 1 and the rear linear vibration track 95 are offset, and an offset transport assembly 107 is provided between them. The offset transport assembly 107 includes a transport electric slide 108, with a rear carrier 109 on its moving end. The rear carrier 109 has multiple transport slots 110 for transporting terminals. A stand 111 is also provided on the side of the transport electric slide 108, and a transport cylinder 112 is mounted on the stand 111. The extended end of the transport cylinder 112 is connected to a claw 113 for moving the terminals in the transport slots 110 of the rear carrier 109 to the linear vibration slots 96 of the rear linear vibration track 95. This design enables the orderly transport of terminals from the front transmission platform 1 to the rear transmission platform 1 for orderly pin insertion.

[0075] The present invention also provides a manufacturing process for an automatic terminal pin insertion device, comprising the following steps:

[0076] a. Terminal feeding: The terminals are fed by the linear vibrating conveyor component of the terminal feeding mechanism, and then the staggered feeding component of the terminal feeding mechanism moves the rows of terminals to the front end of the transmission platform. The linear vibrating conveyor component drives the linear track to vibrate through a linear vibrator, thereby moving the terminals on the linear track. When the terminals are conveyed to the staggered carrier of the staggered feeding component, the staggered electric slide pushes the positioning plate to move horizontally. The positioning plate drives the staggered carrier to move horizontally to the front end of the transmission platform and connect with the transmission platform.

[0077] b. Terminal transportation: The terminals in rows on the misaligned carrier are moved to the transmission platform by the lever of the claw assembly. The lever is driven to perform a forward-right-backward-left cycle by the cooperation of the horizontal and vertical cylinders on the claw assembly, so as to realize the stepping action of the terminals on the transmission platform.

[0078] c. Feeding of pin strip: The pin strip on the take-up reel is pulled out by the feeding assembly, and during the pulling out of the pin strip, the cutting mechanism drives the cutting knife to split the pin strip in two.

[0079] d. Terminal pins: Multiple double-sided pin insertion devices perform the pin insertion process simultaneously. The pin strip feeding mechanism in the double-sided pin insertion device transports two separated pin strips to the pin insertion mechanism, and the pin insertion mechanism inserts the pin strips into the corresponding terminals on the transmission platform.

[0080] e. Waste strip removal: The terminal with the pin is conveyed to the moving rail of the waste strip removal mechanism by the lever of the claw assembly. The moving rail is pushed out by the push assembly, so that the terminal on the moving rail is completely moved to the flipping table. The flipping assembly rotates the flipping table, so that the terminal is moved above the cutting assembly. The terminal is clamped by the tensioning assembly. The cutting assembly is started to cut off the waste strip of the pin on the terminal. After the waste strip on the pin is cut off, the flipping assembly reverses the flipping table to release the tensioning assembly from the terminal. Finally, the moving rail is pulled back to the initial position by the push assembly.

[0081] f. Circulating pin insertion: The terminal with pins is pushed to the rear carrier of the misaligned transport component by the lever of the claw assembly. Then, the rear carrier is pushed to the side of the terminal feeding mechanism of the next transmission platform by the transport cylinder on the misaligned transport component. The transport cylinder on the misaligned transport component drives the claw to move the terminal in the transport groove of the rear carrier to the straight vibration groove of the rear straight vibration track. This is done in a circulating manner until the terminal is full of pins.

[0082] The above process can automatically process terminals for pin insertion, and the pin insertion process can be carried out simultaneously in multiple channels and multiple stations. It not only has high production efficiency, but also protects the pin strip, thereby significantly improving the product qualification rate and bringing good economic benefits to enterprises.
