Description

Technical Field

[0001] This utility model relates to the field of plug-in machine technology, and in particular to a plug-in machine for fuse terminals on electrical box circuit boards. Background Technology

[0002] The copper terminal pins of the fuse in the central electrical box are interference-fitted with the holes on the circuit board, unlike the clearance fit of other electronic component pins. During the insertion process, precise feeding must be ensured, and the position of the terminal after being picked up must be consistent (such as vertical direction, front and back position direction, etc.) in order to achieve accurate insertion, ensure insertion quality, and improve product production quality and efficiency.

[0003] However, existing central electrical box fuse terminals cannot achieve precise insertion or batch automatic insertion during the insertion process. If the copper terminals are skewed after being grabbed during the insertion process, they cannot be inserted normally, thus affecting the insertion quality and speed.

[0004] To address the aforementioned issues, existing technologies employ specialized calibration equipment to calibrate the plug-in pins. However, in actual production, the calibrated copper terminals are prone to deformation during transportation and loading, resulting in pin misalignment and preventing proper plug-in assembly. This affects both production efficiency and plug-in quality.

[0005] Chinese patent document CN105633758B discloses a terminal insertion machine's insertion mechanism, which includes a gantry frame and several insertion devices. The insertion device includes: a frame; a terminal feeding device installed in the frame; a cutting device including left and right cutters disposed in front of the discharge port of the terminal feeding device, and first and second cam mechanisms respectively for driving the left and right cutters to cut the terminal material; and a clamping insertion device including a chuck installed in the frame, a third cam mechanism for driving the chuck to move up and down, and a top opening rod and a fourth cam mechanism for driving the chuck to open. The first, second, third, and fourth cam mechanisms are driven by the same drive shaft.

[0006] The above technical solution integrates the automatic feeding, cutting, insertion, and discharge functions of terminal components into one, so as to achieve precise and fast insertion. However, the above technical solution adopts a fully integrated operation. Although it can achieve precise insertion, it is not suitable for fast and precise insertion of fuse terminals and circuit boards with interference fit in central electrical boxes. Moreover, it has a complex structure and is not suitable for specialized single terminal insertion companies. Utility Model Content

[0007] The purpose of this invention is to solve the problems of existing automatic insertion mechanisms, which cannot meet the requirements of precise insertion of copper terminals and terminal sockets under interference fit conditions. In the automatic insertion process, if the copper terminal is skewed after being grasped, it cannot be inserted normally, thus affecting the insertion quality and speed. The invention provides an electrical box circuit board fuse terminal insertion machine that can achieve precise insertion of terminals and terminal sockets under interference fit conditions, ensuring interference fit quality, good insertion quality, and high efficiency.

[0008] The technical solution adopted by this utility model to achieve its invention objective is: an electrical box circuit board fuse terminal insertion machine, including a vibratory feeder, a clamping and moving mechanism, and a circuit board carrying and feeding mechanism. An automatic clamping mechanism is provided on the clamping and moving mechanism, and a guiding and correcting mechanism is provided on the circuit board carrying and feeding mechanism, which is provided with several guiding and correcting slots. This insertion machine uses a vibratory feeder to automatically sort and transport terminals. The circuit board to be inserted is placed on the circuit board carrying and feeding mechanism, and the terminals are picked up and inserted by the automatic clamping mechanism on the clamping and moving mechanism. Specifically, the clamping and moving mechanism drives the automatic clamping mechanism to achieve horizontal and vertical movement, thereby realizing the picking and insertion operation. Since the fuse terminal and the terminal socket on the circuit board need to be interference-fitted, the positional accuracy of the terminal pins and the terminal sockets on the circuit board in the horizontal and vertical directions must be ensured to achieve the desired result. To ensure precise insertion of terminals, a guiding and correcting mechanism is installed on the circuit board feeding mechanism to avoid defects such as misaligned terminal pins. This mechanism uses guiding and correcting slots to guide and correct the terminal pins before insertion, ensuring precise insertion of each terminal. Specifically, the terminal, held by the automatic clamping mechanism, is first guided and corrected by the guiding and correcting slots before being inserted into the terminal socket on the circuit board. This achieves a precise, interference-fit insertion of the terminal and the circuit board, resulting in high insertion accuracy, high efficiency, and speed, without affecting insertion efficiency or quality due to pin defects.

[0009] Preferably, the guide correction groove is trapezoidal in shape, with an upper guide opening and a lower limiting correction opening from top to bottom. The width of the upper guide opening is greater than the width of the lower limiting correction opening. The trapezoidal shape is designed to accommodate the terminal structure and meet the requirements for terminal pin limiting correction. The wider upper guide opening facilitates smooth insertion of the terminal into the guide correction groove, while the trapezoidal structure does not hinder the downward insertion of the terminal. The lower limiting correction opening, in conjunction with the terminal pin design, limits and corrects the pin when it malfunctions, ensuring that the pin can pass through the lower limiting correction opening into the terminal socket on the circuit board for interference fit insertion. This saves time that would otherwise be required to pick out or individually correct defective terminals, greatly improving terminal insertion efficiency and ensuring insertion quality.

[0010] Preferably, the guiding and correcting mechanism includes a guiding and correcting plate, which is movably disposed within the circuit board bearing and feeding mechanism and horizontally positioned on the circuit board to be inserted. Since the terminal socket positions differ on different circuit boards, to meet the needs of inserting circuit boards of different specifications, the guiding and correcting mechanism mainly includes a guiding and correcting plate, which is movably disposed to facilitate removal after circuit board insertion, allowing for easy placement and removal of the circuit board and easy replacement of different guiding and correcting plates. In use, the guiding and correcting plate is placed on the circuit board after the inserted circuit board is in place, ensuring the guiding and correcting slots are aligned with the terminal sockets, thereby achieving a limiting and correcting function.

[0011] Preferably, several guide correction slots are parallel to each other on the guide correction plate, and each guide correction slot has a guide plate side opening on one side of the guide correction plate. The guide correction slots on the guide correction plate and the guide plate side opening on one side facilitate the removal of the guide correction plate from the side after the circuit board is inserted, without being affected by the terminals on the circuit board, thus facilitating the continued use of the guide correction plate.

[0012] Preferably, the vibratory feeder includes a vibratory feeder hopper and a linear vibrator, wherein the linear vibrator is provided with a linear vibration groove for zero-clearance terminal fit. Since the terminals and circuit boards require interference fit insertion, the linear vibration groove on the linear vibrator is designed to fit the terminals with zero clearance in order to ensure accurate terminal feeding during the vibratory feeding process. This prevents defective terminals from occurring during feeding and further ensures accurate subsequent insertion.

[0013] Preferably, the clamping and moving mechanism includes a vertical support, an X-axis ball screw drive mechanism, and a Y-axis ball screw drive mechanism mounted on the vertical support. The clamping and moving mechanism is designed to enable the automatic clamping mechanism to move horizontally and vertically, thereby achieving automatic part removal. Therefore, the clamping and moving mechanism is equipped with X-axis and Y-axis ball screw drive mechanisms. The use of ball screw drives ensures precise control and high transmission accuracy, guaranteeing accurate control of horizontal and vertical positions, thus achieving precise insertion.

[0014] Preferably, the X-axis ball screw transmission mechanism is mounted on a vertical support via an X-axis slide, and the X-axis ball screw transmission mechanism includes an X-axis stepper motor and an X-axis ball screw; the Y-axis ball screw transmission mechanism is mounted on the X-axis slide via a Y-axis slide, and the Y-axis ball screw transmission mechanism includes a Y-axis stepper motor and a Y-axis ball screw.

[0015] Preferably, the circuit board carrying and feeding mechanism includes a carrying support column, a carrying base plate mounted on the carrying support column, and a circuit board feeding mechanism mounted on the carrying base plate. The circuit board carrying and feeding mechanism is designed to achieve precise movement control of the circuit board position during the insertion process, thereby changing the position of the terminal sockets. This allows the inserted terminals to move and make way for uninserted terminal sockets. Therefore, the circuit board feeding mechanism is provided to drive the circuit board to move forward.

[0016] Preferably, the circuit board feeding mechanism includes a feeding base, a feeding stepper motor, and a feeding ball screw. The circuit board support and positioning plate is mounted on the feeding base and is driven by the feeding ball screw to slide back and forth along the feeding base. The movement of the circuit board support and positioning plate by the feeding stepper motor and the feeding ball screw ensures precise control and high transmission accuracy, guaranteeing accurate insertion.

[0017] Preferably, the automatic gripping mechanism includes a parallel opening and closing gripper body, grippers, and a replaceable terminal clamp plate mounted on the grippers. To ensure that the terminal's accuracy is not affected during gripping, a specially designed terminal clamp plate is used. The terminal clamp plate grips the end faces on both sides of the terminal's elastic opening, preventing any impact on the terminal's quality and ensuring the terminal's performance requirements after insertion, thus achieving precise insertion.

[0018] The beneficial effects of this utility model are as follows: This electrical box circuit board fuse terminal insertion machine, by setting a zero-clearance straight vibration groove on the straight vibrator, accurately conveys the terminals. Simultaneously, a guiding and correcting mechanism is set up during the insertion process. The guiding and correcting groove limits and corrects the terminal pins during insertion, ensuring the accuracy of the horizontal and vertical position of the terminal pins relative to the terminal sockets on the circuit board. This achieves precise interference fit insertion of the terminals and the circuit board, resulting in high insertion accuracy, high efficiency, and speed. Poor pin placement will not affect insertion efficiency or quality. Furthermore, the automatic insertion process is precise and efficient, making it widely applicable to terminal insertion applications requiring interference fit. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Example 1: In Figure 1, Figure 2 , Figure 3 In the embodiment shown, an electrical box circuit board fuse terminal insertion machine is provided. The insertion machine mainly includes a vibratory plate 4, a clamping and moving mechanism 5 and a circuit board carrying and feeding mechanism 7. An automatic clamping mechanism 6 is provided on the clamping and moving mechanism 5, and a guiding and correcting mechanism 8 is provided on the circuit board carrying and feeding mechanism 7. The guiding and correcting mechanism is provided with a plurality of guiding and correcting grooves 82.

[0034] like Figure 8 , Figure 9 , Figure 10 As shown, the guiding and correcting mechanism 8 mainly includes a horizontally arranged guiding and correcting plate 81. The guiding and correcting plate 81 is movably arranged inside the circuit board bearing and feeding mechanism 7, so that when the circuit board to be plugged in is placed and positioned on the circuit board bearing and positioning plate 94, the corresponding terminal socket will horizontally position the guiding and correcting plate 81 on the circuit board to be plugged in.

[0035] The guide correction groove 82 is arranged in a trapezoidal structure. The guide correction groove 82 is provided with an upper guide opening 84 and a lower limiting correction opening 85 from top to bottom. The width of the upper guide opening is greater than the width of the lower limiting correction opening.

[0036] A plurality of guide correction grooves 82 are opened in parallel on the guide correction plate 81, and the guide correction grooves 82 have a guide plate side opening 83 on one side plate surface of the guide correction plate 81.

[0037] The vibratory feeder 4 mainly includes a vibratory feeder hopper 41 and a straight vibrator 43. The straight vibrator 43 is provided with a terminal zero-gap fitting straight vibratory groove 44. The terminals are vibrated and transported into the straight vibratory groove of the straight vibrator through the vibratory feeder hopper, and after being sorted, they are arranged and sequentially transported to the outlet of the straight vibratory groove.

[0038] The clamping and moving mechanism 5 mainly includes a vertical support 51, an X-axis ball screw transmission mechanism 53 and a Y-axis ball screw transmission mechanism 55 mounted on the vertical support 51. The X-axis ball screw transmission mechanism 53 is mounted on the vertical support 51 via an X-axis slide 52, and includes an X-axis stepper motor 531 and an X-axis ball screw 532. The Y-axis ball screw transmission mechanism 55 is mounted on the X-axis slide via a Y-axis slide 54, and includes a Y-axis stepper motor 551 and a Y-axis ball screw 552.

[0039] The circuit board carrying and feeding mechanism 7 mainly includes a carrying support column 71, a carrying base plate 72 mounted on the carrying support column 71, and a circuit board feeding mechanism 9 mounted on the carrying base plate 72. The circuit board feeding mechanism 9 includes a feeding base 91, a feeding stepper motor 92, and a feeding ball screw 93. The circuit board carrying and positioning plate 94 is mounted on the feeding base 91 and is driven by the feeding ball screw 93 to reciprocate along the feeding base 91. The automatic clamping mechanism 6 includes a parallel opening and closing gripper body 61, grippers 62, and a replaceable terminal clamping plate 63 mounted on the grippers 62. The terminal clamping plate 63 is used to clamp the sides of the elastic openings of the terminals, thereby ensuring that the terminals are not affected during the clamping process.

[0040] like Figure 7 , Figure 11 As shown, during operation, the X-axis ball screw transmission mechanism 53 actuates, driving the automatic clamping mechanism 6 to move horizontally in a linear motion until it reaches the terminal outlet of the vibrator 43. Then, the Y-axis ball screw transmission mechanism 55 actuates, driving the automatic clamping mechanism 6 to move downward. The automatic clamping mechanism 6 actuates, and the terminal clamping plate 63 opens to clamp the fuse terminal 20. The Y-axis ball screw transmission mechanism 55 moves upward to reset. The X-axis ball screw transmission mechanism 53 actuates, moving upward towards the circuit board 10 where the terminal is to be inserted. Then, the Y-axis ball screw transmission mechanism 55 moves downward, and the automatic clamping mechanism 6 inserts the terminal 20 into the guide correction groove 82 above the circuit board. After the guide correction groove 82 limits and corrects the terminal pins, the terminal is finally inserted into the terminal socket 101 on the circuit board, achieving an interference fit. The automatic clamping mechanism 6 releases the terminal, completing the insertion of one terminal. Then, the above operation is repeated. At this time, the movement of the circuit board feeding mechanism 9 moves the position of the terminal already inserted on the circuit board backward, and moves the position of the terminal socket without the terminal to the plug-in position for terminal insertion.

[0041] Example 2: See Figures 1-3 In this embodiment, an electrical box circuit board fuse terminal insertion machine includes a workbench 1, on which a control box 2 and a button box 3 are provided, and the automatic insertion of the insertion machine is controlled by the control box 2.

[0042] like Figure 12 As shown, the central electrical box circuit board 10 has two rows of terminal sockets 101 located at the center of its upper edge. Fuse terminals 20 need to be inserted into each of the two rows of terminal sockets 101. The fuse terminals 20 are copper plugs with two terminal pins 201. The pins of the fuse terminals and the terminal sockets are interference-fitted. Therefore, during the insertion process, it is required to ensure the consistency of the position of the terminal pins and the terminal sockets in both the vertical and front-back directions, and the terminal pins must not be misaligned or exhibit other defects.

[0043] Meanwhile, the position of the terminal sockets of circuit board plug terminals of different sizes can be adjusted through the control box 2 to meet the needs of different circuit board terminal plugging.

[0044] The insertion machine mainly includes a vibratory feeder 4 mounted on the workbench 1, a clamping and moving mechanism 5, an automatic clamping mechanism 6 mounted on the clamping and moving mechanism 5, an electrical box circuit board carrying and feeding mechanism 7, and a guiding and correcting mechanism 8.

[0045] The workbench 1 includes a support frame 11 and a work surface 12. The work surface 12 is generally rectangular. A vibratory feeder 4 and an electrical box circuit board bearing feeding mechanism 7 are arranged on the work surface 12 from left to right. The vibratory feeder 4 mainly includes a vibratory feeder hopper 41, a base 42, a vibratory feeder controller, and a linear vibrator 43. The specific structure of the vibratory feeder can be designed based on existing structures for terminal conveying, allowing the terminals vibrated from the vibratory feeder hopper to be conveyed downwards into the linear vibrating groove 44 of the linear vibrator 43, where they are arranged and conveyed in an array. Furthermore, the fit between the linear vibrating groove 44 and the terminals is zero-clearance.

[0046] A pulse electromagnet is installed below the vibratory feeder hopper 41. The vibratory feeder controller is located inside the chassis 42. Controlled by the controller, the vibratory feeder hopper 41 vibrates vertically. The vibratory feeder applies intermittent force at a certain frequency to the vibratory feeder hopper 41, causing it to vibrate vertically and circumferentially, propelling the terminals forward at an angle. This arranges the terminals neatly in a predetermined direction within the terminal track that mates with the terminals. Consequently, the terminals placed inside the vibratory feeder hopper 41 are automatically and orderly oriented with their pins facing downwards, vibrating sequentially into the vertical vibration groove 44 of the vertical vibrator 43 and arranged in a display configuration.

[0047] The free end of the vibrator 41 extends to the side of the electrical box circuit board bearing feed mechanism 7.

[0048] The clamping and moving mechanism 5 is located on the worktable 12 where the electrical box circuit board bearing and feeding mechanism 7 is located and is above the electrical box circuit board bearing and feeding mechanism 7.

[0049] like Figure 4 , Figure 6 As shown, the electrical box circuit board carrying and feeding mechanism 7 includes a carrying support column 71, a carrying base plate 72 disposed on the carrying support column 71, and a circuit board feeding mechanism 9 disposed on the carrying base plate 72.

[0050] The circuit board feeding mechanism 9 includes a feeding base 91, a feeding stepper motor 92, a feeding ball screw 93, and a circuit board bearing positioning plate 94.

[0051] The feed base 91 includes a feed slide 911, a feed slider 912, and a base support plate. The base support plate includes a front base support plate 913 and a rear base support plate 914. A feed slide rail 915 is provided on the feed slide 911.

[0052] The feed slide 911 is horizontally arranged on the worktable 12 and is arranged back and forth along the width direction of the worktable 12. The base support plate is vertically arranged at both ends of the feed slide rail 915, that is, the front support plate 913 of the base is vertically arranged at the front end of the feed slide rail 915, and the rear support plate 914 of the base is vertically arranged at the rear end of the feed slide rail 915.

[0053] A set of slider guide rods 916 is provided between the front support plate 913 and the rear support plate 914 of the base. In this embodiment, two slider guide rods are provided.

[0054] The feed stepper motor 92 is horizontally positioned, and its output shaft passes vertically through the front support plate 913 of the base. The feed ball screw 93 is connected to the output shaft of the feed stepper motor 92 and is also connected to the feed slider 912. A feed slide rail 915 is provided on the feed slide block 911, and the feed slider 912 is slidably mounted on the feed slide rail 915 and driven to slide along the feed slide rail 915 by the feed stepper motor 92.

[0055] The circuit board support positioning plate 94 includes a horizontally arranged support positioning plate body 941 and side baffles 942 arranged on both sides of the support positioning plate body 941. The side baffles 942 are arranged on the support positioning plate body 941 along the feed direction of the feed ball screw. A support boss 943 is provided between the side baffles 942 and the support positioning plate body 941, and a positioning pin 944 is provided on the support positioning plate body 941 near the support boss 943.

[0056] like Figure 5 As shown, the clamping and moving mechanism 5 includes a vertical support 51, an X-axis slide 52 disposed on the upper end of the vertical support 51, an X-axis ball screw transmission mechanism 53 disposed on the X-axis slide 52, a Y-axis slide 54 disposed on the X-axis ball screw transmission mechanism 53, and a Y-axis ball screw transmission mechanism 55 disposed on the Y-axis slide 54.

[0057] The X-axis slide table 52 includes an X-axis slide table base 521, X-axis slide table support plates 522 disposed at both ends of the X-axis slide table base 521, and an X-axis slider 523 slidably disposed on the X-axis slide table base 521. An X-axis slide table rail 524 is arranged parallel to the X-axis slide table base 521, and an X-axis slider groove 525 is correspondingly disposed on the X-axis slider 523, the X-axis slider groove 525 slidingly engaging with the X-axis slide table rail 524.

[0058] The X-axis ball screw transmission mechanism 53 includes an X-axis stepper motor 531 and an X-axis ball screw 532 driven to rotate by the X-axis stepper motor 531. The X-axis ball screw 532 is connected to the X-axis slider 523. The X-axis stepper motor 531 drives the X-axis ball screw 532 to rotate, thereby causing the X-axis slider 523 to move horizontally linearly along the X-axis slide base plate 521. The Y-axis slide 54 is fixedly connected to the X-axis slider 523. The linear motion of the X-axis slide 523 drives the Y-axis ball screw transmission mechanism 55 on it to move horizontally linearly.

[0059] The Y-axis slide table 54 includes a Y-axis slide table base 541, Y-axis slide table support plates 542 disposed at both ends of the Y-axis slide table base 541, and a Y-axis slider 543 slidably disposed on the Y-axis slide table base plate 542. A Y-axis slide table rail 544 is arranged parallel to the Y-axis slide table base 541, and a corresponding Y-axis slider groove 545 is provided on the Y-axis slider 543, the Y-axis slider groove 545 slidingly engaging with the Y-axis slide table rail 544.

[0060] The Y-axis ball screw transmission mechanism 55 includes a Y-axis stepper motor 551 and a Y-axis ball screw 552 that is driven to rotate by the Y-axis stepper motor 551. The Y-axis ball screw 552 is connected to the Y-axis slider 543. The Y-axis ball screw converts the rotational motion into linear motion, thereby driving the automatic clamping mechanism 6 to make up-down linear motion through the Y-axis slider 543.

[0061] like Figure 11 As shown, the automatic gripping mechanism 6 includes a parallel opening and closing gripper body 61, a gripper 62 disposed on the parallel opening and closing gripper body 61, and a terminal clamp 63 that is replaceable and detachable disposed on the gripper 62.

[0062] The terminal clamp 63 includes a jaw connecting seat 631 and a clamp body 632. The clamp body 632 has an overall T-shaped structure and is integrally or separately fixed to the inner side of the jaw connecting seat 631. The clamp body 632 uses a clamp with slight elasticity; in this embodiment, the clamp body has a planar structure. The two clamp bodies are used to clamp the terminal, specifically the two open sides of the terminal. This direct clamping method does not cause terminal deformation and does not affect the quality of the terminal insertion. The jaw connecting seat 631 is provided with multiple jaw connecting holes 633 for fixed connection with the jaws 62. The multiple jaw connecting holes can be selected for connection and fixing as needed.

[0063] In other embodiments, a groove-shaped structure matching the shape of the terminal can be provided on the clamping plate body 632 to clamp the terminal and ensure that the terminal does not deform during the clamping process.

[0064] like Figure 7 , Figure 11 As shown, during operation, the vibratory feeder vibrates the terminals 10 to the linear vibrator, where they are arranged and transported sequentially within the linear vibrating groove. The X-axis ball screw drive mechanism 53 actuates, driving the automatic clamping mechanism 6 to move horizontally to the terminal outlet of the linear vibrator 43. Then, the Y-axis ball screw drive mechanism 55 actuates, driving the automatic clamping mechanism 6 to move downward. The automatic clamping mechanism 6 actuates, and the terminal clamping plate 63 opens to clamp the fuse terminal 20. The Y-axis ball screw drive mechanism 55 moves upward to reset. The X-axis ball screw drive mechanism 53 actuates, moving upward above the circuit board 10 where the terminal is to be inserted. Then, the Y-axis ball screw drive mechanism 55 moves downward, and the automatic clamping mechanism 6 inserts the terminal 20 into the guide correction groove 82 above the circuit board. After the guide correction groove 82 limits and corrects the terminal pins, the terminal is finally inserted into the terminal socket 101 on the circuit board, achieving an interference fit. The automatic clamping mechanism 6 releases the terminal, completing the insertion of one terminal. The above operation is then repeated. At this time, the movement of the circuit board feeding mechanism 9 moves the position of the terminal already inserted on the circuit board backward, and moves the position of the terminal socket without the terminal to the plug-in position for terminal insertion.

[0065] Because the terminals may deform during vibration and transportation, preventing proper insertion, a guiding and correction mechanism 8 is provided on the circuit board.

[0066] like Figure 8 , Figure 9 , Figure 10As shown, the guiding and correcting mechanism 8 includes a guiding and correcting plate 81. Several guiding and correcting grooves 82 are provided on the guiding and correcting plate 81 at positions corresponding to the terminal holes on the circuit board. The guiding and correcting grooves 82 are opened along one side of the guiding and correcting plate 81 and penetrate through that side to form a guiding plate side opening 83. In use, the guiding plate side opening faces the vibrator side.

[0067] The guide correction groove 82 has a trapezoidal groove structure. From top to bottom, the guide correction groove 82 has an upper guide opening 84 and a lower limiting correction opening 85. The width of the upper guide opening 84 is greater than the width of the lower limiting correction opening 85. The width of the lower limiting correction opening 85 is consistent with the width of the terminal pin. When the terminal is inserted into the terminal socket of the circuit board from top to bottom, if the terminal pin is deformed or misaligned, it can be guided and corrected by the width of the guide correction groove bottom at the mating point with the circuit board terminal socket, thereby ensuring smooth terminal insertion and insertion quality.

[0068] The electrical box circuit board fuse terminal insertion machine in the above embodiment automatically calibrates the terminals before insertion, achieving precise insertion between the terminals and the terminal sockets on the circuit board. This ensures insertion accuracy and quality, and solves the problems in the prior art where incorrect pin alignment during terminal insertion leads to inaccurate insertion, affecting insertion efficiency and quality.
