Description

Technical Field

[0001] This utility model relates to the field of magnetic system installation technology, and in particular to a terminal assembly machine for magnetic systems. Background Technology

[0002] The magnetic system is a core component of a circuit breaker, used to trip the circuit breaker by impacting the free-trip module in the event of an abnormal current. It typically consists of components such as a coil, stationary contacts, and terminals. A utility model patent with patent number CN222957973U discloses an assembly device for the magnetic system within a circuit breaker. This device uses a ring conveyor belt to transport the carrier, allowing for the simultaneous assembly of multiple magnetic systems and improving overall assembly efficiency.

[0003] As a key connecting component of the magnetic system, the assembly accuracy of the terminal block directly affects the reliability of the magnetic system. The terminal block consists of a rectangular terminal frame, a terminal plate, and screws. The terminal frame has a rectangular cavity structure with through holes on both side walls. The terminal plate is a Z-shaped plate structure formed by bending in one piece, including a main body, a plug-in part and a connecting part formed by bending the two ends of the main body in opposite directions. The main body, plug-in part, and connecting part are perpendicular to each other to form a Z shape. The width of the plug-in part of the terminal plate is adapted to the width of the terminal frame cavity. The plug-in part is fitted into the terminal frame. The screw is screwed onto the terminal frame and, after being screwed in, is used to press the wires passing through the terminal frame against the surface of the plug-in part. In the current assembly equipment for the internal magnetic system of circuit breakers, during the terminal assembly process, a rectangular terminal frame is usually placed horizontally on a carrier. The plug part of the terminal block needs to be inserted into the cavity of the terminal frame in a horizontal direction. Because the width of the plug part and the width of the terminal frame cavity are precisely matched and the gap is extremely small, it is easy to get stuck due to misalignment when inserting horizontally, resulting in low assembly efficiency and easy damage to components, affecting the overall assembly quality. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a terminal assembly machine for a magnetic system. By "embedding the terminal block in the vertical diagonal area of ​​the terminal frame", the terminal block can be easily inserted, and the whole process can be automated.

[0005] The technical solution of this utility model is: a terminal assembly machine for a magnetic system, including a frame, on which a carrier conveyor line is provided, and a terminal board loading unit, a terminal frame loading and straightening unit and a screw assembly unit are arranged sequentially along the conveying direction of the carrier conveyor line; The carrier conveyor line is equipped with several terminal block carriers. Each terminal block carrier includes a base, and the upper surface of the base is provided with a V-shaped positioning groove, a horizontal bearing surface, and a terminal block station. The horizontal bearing surface is located on the side of the V-shaped positioning groove. The V-shaped positioning groove is adapted to one edge of the lower end of the rectangular terminal block, so that the rectangular terminal block is tilted and placed on the base with its inner diagonal vertical. The horizontal bearing surface is used for positioning the rectangular terminal block horizontally. The terminal block station is used for positioning the terminal block, so that the terminal block is in a side-lying state and its plug-in part corresponds to the upper part of the V-shaped positioning groove. The terminal block loading unit is used to move and position the terminal block in a side-lying state to the terminal block station. The wiring frame loading and straightening unit is used to place the lower edge of the rectangular wiring frame and the side closest to the horizontal bearing surface into the V-shaped positioning groove, so that the rectangular wiring frame is tilted and upright, and drives the rectangular wiring frame to move along the V-shaped positioning groove to the assembly position, so that the plug part of the wiring board is inserted into the vertical inner diagonal area of ​​the rectangular wiring frame; the wiring frame loading and straightening unit can also drive the tilted rectangular wiring frame to flip over to the horizontal bearing surface side, so that it is in a flat state and the lower end of the rectangular wiring frame is vertically upright to approach the plug part of the wiring board; The screw assembly unit is used to deliver screws and thread them onto a rectangular junction box that is lying flat.

[0006] Using the above technical solution, the carrier conveyor line on the frame drives several terminal carriers through the terminal board loading unit, the terminal frame loading and alignment unit and the screw assembly unit in sequence according to the preset rhythm, realizing the fully automated flow and completely eliminating the positioning deviation and efficiency bottleneck caused by manual intervention.

[0007] By precisely fitting the V-shaped positioning groove on the carrier with one edge of the lower end of the rectangular terminal frame, the V-shaped structure forces the rectangular terminal frame to tilt and stand upright with its inner diagonal remaining vertical. This vertical inner diagonal area forms the longest through space inside the rectangular terminal frame, providing ample insertion allowance for the connector of the terminal block. The terminal block station pre-positions the terminal block in a side-lying position, ensuring the connector is precisely aligned with the top of the V-shaped positioning groove. When the terminal block loading and straightening unit moves the rectangular terminal block smoothly along the V-shaped positioning groove to the assembly position, the connector smoothly inserts into the vertical inner diagonal area of ​​the rectangular terminal block. This design completely avoids the problems of jamming and scratching caused by the extremely small gaps and misalignment of traditional horizontal insertion, protecting the structural integrity of the plug-in part and the inner wall of the rectangular wiring frame. Subsequently, the wiring frame loading and straightening unit drives the rectangular wiring frame to tilt to the side of the horizontal bearing surface, so that it is in a flat position, and the lower end of the rectangular wiring frame stands upright and closely against the plug-in part, forming a stable pre-assembly positioning, avoiding relative displacement between the two during subsequent screw assembly. Finally, the screw assembly unit accurately screws in the screws. The entire process is seamless and the positioning accuracy and assembly efficiency are greatly improved. The product consistency is significantly better than that of traditional assembly methods.

[0008] A further feature of this invention is that the carrier is provided with a wire frame stop and a movable clamp at both ends of the horizontal bearing surface, and the wire frame stop extends into the V-shaped positioning groove to limit the rectangular wiring frame that moves along the V-shaped positioning groove to the assembly position. The lower end of the movable clamping block is rotatably connected to the carrier via a hinge shaft, and the upper end is the clamping end. An elastic reset element is provided on the carrier. The elastic reset element is a tension spring, one end of which is hooked to the connecting shaft at the upper end of the movable clamping block, and the other end is hooked to the fixed shaft of the carrier. When the rectangular wiring frame is in a flat state, the elastic reset element can drive the clamping end of the movable clamping block to move closer to the wire frame stop, so as to cooperate with the wire frame stop to achieve the clamping and positioning of the rectangular wiring frame.

[0009] With the above-described further configuration, the wire frame stops at both ends of the carrier on the horizontal bearing surface extend into the V-shaped positioning grooves. When the rectangular terminal frame moves along the V-shaped positioning grooves to the assembly position, the wire frame stops act as limiters, precisely restricting the movement of the rectangular terminal frame. This ensures that the rectangular terminal frame is in the optimal alignment position directly below the connector during each assembly, avoiding assembly deviations caused by displacement. The movable clamping block is rotatably connected to the carrier via a hinge shaft, allowing its clamping end to swing flexibly. As the rectangular terminal frame tilts to a flat position, its edges press against the clamping end, driving the movable clamping block to rotate away from the wire frame stops. Simultaneously, the elastic reset component stores force. When the rectangular terminal frame is fully in contact with the horizontal bearing surface, the elastic reset component releases its reset force, pulling the movable clamping block through the hooked connecting shaft, causing the clamping end to quickly approach the wire frame stops. The two work together to clamp and position the rectangular terminal frame. This flexible clamping structure provides a continuous and stable clamping force, ensuring that the rectangular terminal block does not shift or move when it lies flat, providing a displacement-free reference for screw installation. It also has adaptive adjustment capabilities, adapting to rectangular terminal blocks of different widths, and avoiding frame deformation or surface damage caused by rigid clamping. At the same time, the clamping action is directly triggered by the side-flipping action of the rectangular terminal block, eliminating the need for additional drive mechanisms such as cylinders and motors. This simplifies the equipment structure, reduces energy consumption and failure risk, and achieves a linkage effect of "clamping as soon as the side-flipping is in place".

[0010] A further feature of this invention is as follows: the terminal block station is located on a wire frame stop, the wire frame stop is provided with a contour positioning surface and positioning posts, the contour positioning surface and positioning posts cooperate to achieve positioning of the inner and outer sides of the terminal block; the contour positioning surface has a Z-shaped structure, including a positioning middle surface and a first positioning end surface and a second positioning end surface extending in opposite directions from both ends of the positioning middle surface, the positioning middle surface, the first positioning end surface and the second positioning end surface respectively abut against the outer side of the main body, the plug-in part and the connecting part of the terminal block; multiple positioning posts are provided at intervals along the extension direction of the contour positioning surface, for abutting and limiting the inner side of the terminal block.

[0011] With the above-mentioned further configuration, the Z-shaped contour positioning surface on the wire frame stop is perfectly adapted to the Z-shaped structure of the terminal block. The positioning middle surface is attached to the outer side of the terminal block body, the first positioning end face is attached to the outer side of the plug-in part, and the second positioning end face is attached to the outer side of the connecting part. This three-section comprehensive fit restricts the horizontal displacement and torsional tendency of the terminal block from the outside. Simultaneously, multiple positioning posts spaced along the extension direction of the contour positioning surface form abutment and limitation from the inner side of the terminal block, working in conjunction with the Z-shaped contour positioning surface to form a two-way positioning structure of "outer side fit + inner side tightening." This completely prevents vertical warping, horizontal offset, or angular torsion of the terminal block during assembly, ensuring that the plug-in part always remains vertical and accurately aligned with the inner diagonal area of ​​the rectangular terminal frame. This multi-point, two-way positioning method not only disperses the stress points of the terminal block, avoiding deformation caused by excessive local stress and ensuring the structural integrity of the terminal block, but also allows for the replacement of positioning posts of different diameters, facilitating adaptation to terminal blocks of different thicknesses.

[0012] A further feature of this utility model is that the terminal block feeding unit includes a terminal block feeding tray, a terminal block feeding rail, a terminal block clamping mechanism one, and a terminal block clamping mechanism two. The upstream end of the terminal block feeding rail is connected to the outlet of the terminal block feeding tray, and the downstream end is provided with a terminal block picking position. The terminal block feeding rail is used to sequentially transport multiple vertically placed terminal blocks to the terminal block picking position. The terminal block feeding rail has a terminal block channel inside and a track surface at the upper end. The vertically placed terminal block with its plug-in part facing down is inserted into the terminal block channel, the body part slides on the track surface, and the connecting part extends out of the terminal block channel. The terminal block picking position is provided with a picking window for the plug-in part of the terminal block to be exposed. The first terminal block clamping mechanism is used to clamp the plug-in part of the terminal block at the terminal block picking position and drive the terminal block to rotate around the X-axis, so that the terminal block changes from a vertically placed position to a side-lying position. The second terminal block clamping mechanism is used to clamp the connecting part of the side-lying terminal block and drive the terminal block to rotate around the Z-axis, so that the terminal block is moved and positioned to the terminal block station.

[0013] With a further refinement of the above-mentioned configuration, the terminal block feeding tray achieves directional arrangement of the terminal blocks through vibration. The terminals are then stably conveyed to the terminal block picking position via the terminal block feeding rail. The plug-in portion is inserted downwards into the terminal block channel, the main body slides on the rail surface, and the connecting portion extends out of the channel, ensuring smooth conveying and providing a clear force point for subsequent clamping. The picking window at the terminal block picking position exposes the plug-in portion, facilitating precise clamping by the first terminal block clamping mechanism. After clamping the plug-in portion, the first terminal block clamping mechanism rotates around the X-axis, smoothly converting the terminal block from a vertical position to a side-lying position. Subsequently, the second terminal block clamping mechanism clamps the connecting portion of the side-lying terminal block, rotates around the Z-axis, precisely adjusts the angle, and then moves the terminal block to the terminal block station for positioning. The two-stage clamping mechanism seamlessly integrates state transitions and transfer actions. Precise control of the rotation angle ensures the consistency of the terminal block's state after each positioning, preventing assembly failures due to state deviations. Simultaneously, the entire feeding process requires no manual intervention, achieving full automation from feeding to positioning of the terminal block, significantly improving feeding efficiency and ensuring the efficient operation of the overall assembly process.

[0014] A further feature of this invention is as follows: the terminal block clamping mechanism includes a first gripper, a first auxiliary positioning gripper, a first linear drive module, and a first rotary drive module; the first gripper is used to extend into the material handling window and clamp the plug-in portion of the terminal block, and the first auxiliary positioning gripper is used to abut against the side of the connection portion of the terminal block; the first linear drive module is used to drive the first gripper and the first auxiliary positioning gripper to move linearly, and when the first gripper clamps the plug-in portion, the first auxiliary positioning gripper simultaneously abuts against the connection portion; the first rotary drive module is used to simultaneously drive the first gripper and the first auxiliary positioning gripper to rotate around the X-axis; The second terminal block clamping mechanism includes a second gripper, a second auxiliary positioning gripper, a second linear drive module, and a second rotary drive module; the second linear drive module is used to drive the second gripper and the second auxiliary positioning gripper to move linearly, and when the second gripper clamps the connecting part, the second auxiliary positioning gripper simultaneously abuts against the plug-in part; the second rotary drive module is used to simultaneously drive the second gripper and the second auxiliary positioning gripper to rotate around the Z-axis. The terminal block feeding unit also includes a detection sensor for detecting whether there is material at the terminal block feeding position, and a staggered feeding component for blocking the terminal block to achieve staggered feeding.

[0015] With the above-mentioned further configuration, the first gripper and the first auxiliary positioning gripper of the terminal block clamping mechanism one work together. When the first linear drive module drives them to approach the terminal block picking position, the first gripper extends into the picking window to accurately clamp the plug part of the terminal block, and the first auxiliary positioning gripper simultaneously abuts against the side of the connection part, forming a "multi-position fixing" structure. This effectively prevents the terminal block from shaking, falling, or shifting its state during rotation around the X-axis, ensuring the accuracy of the state transition. The first rotary drive module simultaneously drives the first gripper and the first auxiliary positioning gripper to rotate, so that the terminal block can smoothly complete the state transition from vertical to side-lying. The movement is smooth and impact-free, protecting the terminal block from damage. The second linear drive module of the terminal block clamping mechanism two realizes the horizontal transfer of the terminal block, and the second rotary drive module drives the second gripper to rotate around the Z-axis, accurately adjusting the horizontal angle of the terminal block to ensure that it is fully adapted to the positioning structure of the terminal block station, achieving accurate positioning. In addition, the detection sensors configured in the terminal block feeding unit detect whether there is material at the terminal block picking position in real time. If no material is detected, a feedback signal is sent in time to avoid process interruption caused by the terminal block clamping mechanism being empty. The staggered loading component can block the subsequent terminal blocks from moving forward, realize staggered loading, prevent multiple terminal blocks from congesting at the picking position, ensure the continuity and stability of the loading process, and further improve the overall assembly efficiency.

[0016] A further feature of this invention is as follows: the wiring frame feeding and straightening unit includes a wiring frame feeding tray, a wiring frame feeding rail, a wiring frame clamping mechanism, and a wiring frame straightening mechanism; the upstream end of the wiring frame feeding rail is connected to the outlet of the wiring frame feeding tray, and the downstream end is provided with a wiring frame picking position; the wiring frame feeding rail is used to sequentially transport multiple vertically upright rectangular wiring frames to the wiring frame picking position; the wiring frame picking position is provided with a picking window for the rectangular wiring frames to be exposed; the wiring frame clamping mechanism is used to clamp the rectangular wiring frames at the wiring frame picking position and drive them to rotate around the X-axis, so that the rectangular wiring frames change from a vertically upright position to an inclined upright position, and then transfer and place them in the V-shaped positioning groove of the carrier, and drive the rectangular wiring frames to move along the V-shaped positioning groove to the assembly position; the wiring frame straightening mechanism is used to push the inclined upright rectangular wiring frames to tilt towards the horizontal bearing surface, so that they are in a flat position.

[0017] With a further refinement, the wiring frame feeding tray uses vibration to orient rectangular wiring frames, which are then conveyed to the wiring frame picking position via the wiring frame feeding rail. The channel structure of the wiring frame feeding rail ensures that the rectangular wiring frames are always conveyed vertically. The picking window at the wiring frame picking position exposes the rectangular wiring frames, facilitating clamping by the wiring frame clamping mechanism. After the wiring frame clamping mechanism accurately clamps the rectangular wiring frame at the picking position, it rotates it around the X-axis by a preset angle, changing it from a vertical position to an inclined position. Then, through translation, the rectangular wiring frame is moved into the V-shaped positioning groove of the carrier. The inclined surface of the V-shaped positioning groove constrains the rectangular wiring frame, ensuring it remains stably inclined with its inner diagonal vertical. The wiring frame clamping mechanism continues to move the rectangular wiring frame along the V-shaped positioning groove to the assembly position, ensuring that the connector of the wiring board is accurately inserted into its vertical inner diagonal area. Afterward, the wiring frame straightening mechanism activates, pushing the inclined rectangular wiring frame to tilt towards the horizontal bearing surface, allowing it to smoothly transition to a flat position. The entire process is smooth and precise, and the automated operation greatly improves the efficiency of loading and aligning the wiring frame, shortening the overall assembly cycle.

[0018] A further feature of this invention is as follows: the wire connection frame feeding rail includes a first rail, a second rail, and a third rail connecting the downstream end of the first rail and the upstream end of the second rail. The upstream end of the first rail is connected to the outlet of the wire connection frame feeding tray, and the downstream end of the third rail is provided with a wire connection frame picking position. The first rail transports the rectangular wire connection frame from the wire connection frame feeding tray to the third rail. The rectangular wire connection frame in the third rail is pushed to the second rail by a first pushing mechanism, and the rectangular wire connection frame in the second rail is pushed to the wire connection frame picking position by a second pushing mechanism.

[0019] With a further refinement of the above-mentioned design, the wiring frame feeding rails employ a combination structure of a first rail, a second rail, and a third rail. The first rail smoothly transports the rectangular wiring frames output from the wiring frame feeding tray to the third rail, achieving the initial feeding stage. The first pushing mechanism pushes the rectangular wiring frames in the third rail one by one to the second rail, and the second pushing mechanism then precisely pushes the rectangular wiring frames in the second rail to the wiring frame picking position, forming a single feeding logic of "diversion-buffering-precise pushing". This multi-rail combination design effectively avoids the congestion or insufficient feeding problems caused by the mismatch between the feeding speed and the picking speed of a single linear rail. The third rail can act as a temporary buffer, balancing the feeding and picking rhythms. The step-by-step pushing action of the two-stage pushing mechanism can precisely control the feeding timing and position of each rectangular wiring frame, ensuring that there is only one rectangular wiring frame to be picked up at the wiring frame picking position at any given time, avoiding the stacking or misalignment of multiple rectangular wiring frames, and ensuring the accuracy and smoothness of the wiring frame clamping mechanism's picking action.

[0020] A further feature of this invention is that the wiring frame alignment mechanism and the wiring frame clamping mechanism are respectively located on both sides of the carrier conveyor line; the wiring frame clamping mechanism includes a third gripper, a third linear drive module, and a third rotary drive module. The third gripper is used to extend into the material picking window and clamp the rectangular wiring frame. The third linear drive module is used to drive the third gripper to move linearly, and the third rotary drive module is used to drive the third gripper to rotate around the X-axis; the wiring frame alignment mechanism includes a drive component and a push rod that is driven to extend and retract by the drive component. The push rod extends downward at an angle to above the carrier conveyor line, and the extension action of the push rod lays the inclined rectangular wiring frame flat.

[0021] With a further refinement, the wiring frame alignment mechanism and the wiring frame clamping mechanism are positioned on opposite sides of the carrier conveyor line. This symmetrical layout ensures that their actions do not interfere with each other, applying force to the rectangular wiring frame from different directions and ensuring sufficient operating space. Driven by the third linear drive module, the third gripper of the wiring frame clamping mechanism precisely extends into the material handling window, firmly clamping the rectangular wiring frame. Subsequently, the third rotary drive module activates, causing the third gripper to rotate around the X-axis, smoothly transforming the rectangular wiring frame from a vertical position to an inclined position. Through linear movement, it is accurately transferred to the V-shaped positioning groove of the carrier and continues to move along the V-shaped positioning groove to the assembly position, ensuring precise alignment with the wiring board. Simultaneously, the drive component of the wiring frame alignment mechanism extends the push rod, which contacts the inclined rectangular wiring frame at a downward angle, applying appropriate pushing force to smoothly tilt it towards the horizontal bearing surface, ultimately resulting in a flat position. The entire process, through the precise coordination of the mechanical structure and the collaborative control of the drive module, achieves fully automated operation of the rectangular wiring frame from material picking and state transition to positioning and alignment. The actions are smooth and the error is minimal, significantly improving assembly efficiency and product quality.

[0022] A further feature of this invention is as follows: the screw assembly unit includes a screw screwing machine, a lateral positioning component, and a downward positioning component; the downward positioning component can press against the surface of the rectangular wiring frame in a flat state, and the lateral positioning component is used to abut against one end of the rectangular wiring frame in a flat state; the screw screwing machine includes a screw feeding tube and a screwing component, and the screwing component is used to screw the screw at the outlet of the screw feeding tube into the threaded hole provided at the other end of the rectangular wiring frame.

[0023] With the above-described further configuration, the pressing and positioning components of the screw assembly unit work together to achieve the assembly and positioning of the rectangular terminal frame. When the pressing and positioning component is activated, its pressure head presses against the surface of the rectangular terminal frame in its flat position, restricting its vertical movement. Simultaneously, the lateral positioning component extends and abuts against one end of the rectangular terminal frame, restricting its displacement in the horizontal direction. This ensures that the rectangular terminal frame does not shift or deflect during screw installation, guaranteeing the coaxiality of the threaded hole and the screw, and preventing thread damage, incomplete assembly, or component damage caused by screw misalignment. The screw is gradually screwed into the threaded hole during rotation by the screw-in component. The entire screw assembly process is highly automated, with precise positioning and smooth operation, significantly improving the efficiency and quality of screw assembly.

[0024] A further feature of this invention is that a detection unit is also provided on the frame. The detection unit includes a detection execution component and a positioning and clamping component. The positioning and clamping component is used to abut one end of a rectangular wiring frame in a flat position, and the detection execution component is used to abut the screw screwed to the other end of the rectangular wiring frame to detect the assembly status of the screw.

[0025] With the above-described further configuration, the inspection unit on the frame can inspect the quality of products assembled by the screw assembly unit. When the rectangular terminal frame with screws arrives at the inspection station along the carrier conveyor line, the positioning and clamping assembly activates, its clamping block abuts against one end of the rectangular terminal frame and applies a stable clamping force to ensure the stability of the inspection benchmark. By having the probe of the inspection execution assembly abut against the screw, the exposed length of the screw can be detected, thereby determining whether the screw is screwed in properly, whether there are any problems such as missing screws, loose screws, or excessive tightening. This allows for the timely screening of unqualified products, preventing unqualified terminals from flowing into subsequent processes and ensuring the quality of products leaving the factory.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] like Figure 1-20As shown, the present invention discloses a magnetic system terminal assembly machine, including a frame 1. The frame 1 is provided with a carrier conveyor line 2, and a terminal board loading unit 4, a terminal frame loading and straightening unit 5, a screw assembly unit 6 and a detection unit 10 are sequentially fixedly installed along the conveying direction of the carrier conveyor line. Each unit achieves coordinated action through an electrical control system such as a PLC controller to ensure orderly connection of each link. The carrier conveyor line 2 is equipped with several terminal carriers 3. The carrier conveyor line adopts a conventional belt or chain conveyor structure to drive the terminal carriers to move, or directly pushes the terminal carriers on the carrier conveyor line to move through a cylinder or electric cylinder structure. Specifically, the terminal carrier 3 includes a base 31. The upper surface of the base 31 is machined with a V-shaped positioning groove 32, a horizontal bearing surface 33, and a terminal block station 34. The horizontal bearing surface 33 is located on the side of the V-shaped positioning groove 32. The V-shaped positioning groove 32 is adapted to one side edge of the lower end of the rectangular terminal frame 7, allowing the rectangular terminal frame 7 to be tilted and upright on the base 31 with its inner diagonal vertical. The included angle of the V-shaped positioning groove is adapted to the edge of the rectangular terminal frame, and the groove depth ensures the stable upright position of the terminal frame. The included angle of the V-shaped positioning groove can be designed to be 90°. The horizontal bearing surface 33 is used for horizontal positioning of the rectangular terminal frame 7. The terminal block station 34 is used for positioning the terminal block 8, so that the terminal block 8 is in a side-lying state with its plug-in portion 81 corresponding to the upper part of the V-shaped positioning groove 32. The base 31 has wire frames respectively set at both ends of the horizontal bearing surface 33. The frame includes a stop 35 and a movable clamping block 36. The wire frame stop 35 extends into the V-shaped positioning groove 32 to limit the rectangular wiring frame 7 as it moves along the V-shaped positioning groove 32 to the assembly position. The carrier 31 has a connected movable opening and a receiving opening. The movable clamping block 36 passes through the movable opening. The lower end of the movable clamping block 36 is rotatably connected to the carrier 31 via a hinge shaft, and the upper end is a clamping end 361. An elastic reset member 37 is provided in the receiving opening. The elastic reset member 37 is a tension spring. One end of the spring is hooked to the connecting shaft 362 at the upper end of the movable clamping block 36, and the other end is hooked to the fixed shaft 313 of the carrier 31. When the rectangular wiring frame 7 is in a flat position, the elastic reset member 37 can drive the clamping end 361 of the movable clamping block 36 to move closer to the wire frame stop 35 to cooperate with the wire frame stop 35 to achieve clamping and positioning of the rectangular wiring frame 7. The terminal block station 34 is located on the wire frame stop 35. The wire frame stop 35 is provided with a contour positioning surface 351 and a positioning post 352.

The first rotary drive module can select a rotary cylinder, a rotary motor, or a linear drive to drive the swing arm in an indirect rotation structure according to the actual working conditions. When the first rotary drive module uses a rotary cylinder or a motor, its output end is directly fixedly connected to the gripper bracket. The rotational movement of the cylinder drives the first gripper fixed on the gripper bracket to rotate around the X-axis. When the first rotary drive module uses a linear drive to drive the swing arm, the output end of the linear cylinder or electric cylinder is hinged to one end of the swing arm, and the other end of the swing arm is fixed to the rotating shaft.

[0035] During operation, the wiring frame feeding tray conveys the wiring frames to the first material rail, and then to the third material rail. A first pushing mechanism pushes the wiring frames from the third material rail to the second material rail. A second pushing mechanism then pushes the wiring frames from the second material rail to the wiring frame picking position. A third linear drive module drives a third gripper to approach and clamp the wiring frame. After the wiring frame is removed, a third rotary drive module drives the third gripper to rotate around the X-axis, causing the wiring frame to tilt and stand upright. At this point, the inner diagonal of the rectangular wiring frame is vertical. This, combined with the third linear drive module, allows the wire frame placed on... The terminal block carrier moves the terminal frame along the V-shaped positioning groove to the assembly position, allowing the connector of the terminal block to insert into the vertical inner diagonal area of ​​the rectangular terminal frame. Subsequently, the drive mechanism of the terminal frame alignment is activated, extending the push rod downwards to above the carrier's conveyor line.

[0037] During operation, the downward positioning component activates first, driving the downward block to descend and press against the surface of the horizontally positioned rectangular terminal frame, thus securing it. Simultaneously, the lateral positioning component's lateral drive extends the lateral block, abutting one end of the rectangular terminal frame to further restrict its position. At this point, the screw feed tube delivers screws to the outlet, activating the screw-in component. Its bit aligns with the screw at the screw feed tube outlet, and through the cooperation of the rotary and linear drive modules, the bit gradually screws the screw into the threaded hole of the terminal frame.
