Description

Technical Field

[0001] This invention relates to the field of terminal block wiring equipment technology, and specifically provides an automatic insertion system for wire terminals. Background Technology

[0002] In the field of electrical wiring, wire terminals (such as terminal blocks, terminal strips, etc.) are widely used to achieve reliable connections between wires and equipment. Traditional or currently mainstream wiring methods mainly rely on manual operation, that is, workers manually insert the exposed end of the wire into the terminal hole, and then use tools such as screwdrivers to tighten the clamping screws on the terminal to complete the fixation.

[0003] In scenarios requiring large-scale, high-density wiring (such as the production of control cabinets, distribution panels, and communication equipment), existing terminal block wiring methods often suffer from inefficiency, especially during repeated manual insertion. The low precision of wire insertion during these processes means that not all wires can be aligned with the terminals on the first attempt. This often results in wires needing to be aligned with the insertion holes multiple times, impacting insertion efficiency. Furthermore, repeated collisions between the wire ends and the bottom of the terminals can scratch the terminal block or bend the wires, leading to poor consistency among the terminals and affecting the overall wiring quality of the electrical system. Summary of the Invention

[0004] To address the aforementioned problems, this invention aims to provide a device that automates the entire process from cable gripping, precise positioning, terminal insertion to final tightening, thereby saving labor costs and improving production efficiency.

[0005] The technical solution of the present invention is as follows:

[0006] An automatic insertion system for wire terminal blocks includes a frame with a terminal block mounting module for placing terminal blocks to be inserted. The mounting module controls the terminal blocks to move along their length to sequentially position multiple terminals to preset insertion positions. A tray mounting module, located on one side of the insertion positions, loads a tray with wires on it and controls its rotation via a drive mechanism to position the corresponding wires in preset clamping positions. A clamping and mounting module, located on the other side of the insertion positions, includes a gripper unit for clamping the ends of the wires and a tightening unit for tightening bolts on the terminal blocks. A control system communicates with and coordinates the actions of the mounting module, tray mounting module, and clamping and mounting module. During the insertion process, the insertion positions, clamping positions, gripper units, and tightening units are all located in the same vertical plane.

[0007] Unlike existing manual insertion methods, this invention's control system coordinates the operation of each module. The loading module holds a wire reel with wires, and the clamping unit in the clamping module picks up the wires from the reel and automatically inserts them into the terminal's insertion port. Then, the tightening unit tightens the clamping bolts. The entire process requires no manual intervention to complete the insertion of a single terminal. By controlling the rotation angle of the loading module, the corresponding wire can be rotated to the clamping position of the clamping unit. The insertion position, the clamping position, the clamping unit, and the tightening unit are all in the same vertical plane. As long as the positions of the insertion position and the clamping position remain fixed, the clamping unit does not need to move much to accurately pick up and precisely insert the wires. Subsequent repositioning is also unnecessary, thus achieving high-precision positioning and rapid insertion of the wires.

[0008] Preferably, the gripper unit is fixedly mounted on the frame and includes a first lifting part, a first pushing part, and a gripping claw. The gripping claw can move horizontally linearly toward the insertion station via the first pushing part, and the gripping claw can move vertically via the first lifting part.

[0009] In this solution, the clamping claws can quickly grasp the wires. After clamping the wire end and inserting it into the terminal for fixation, the clamping claws can quickly separate from the wire and reset. Furthermore, since the positions of the insertion station and the standby clamping station are fixed, the clamping claws of the clamping unit only need to perform telescopic translation and vertical lifting, eliminating the need for complex motion commands and drive structures. This effectively reduces the programming difficulty and component manufacturing complexity.

[0010] Preferably, the clamping and mounting module further includes a first frame mounted on the frame, and the tightening unit is mounted on the first frame. The tightening unit is located directly above the gripper unit. The tightening unit includes a second lifting part, a second pushing part, and an electric screwing head. The electric screwing head can achieve horizontal linear movement towards the wire insertion station through the second pushing part, and the electric screwing head can perform vertical translation through the second lifting part. The pushing directions of the first pushing part and the second pushing part are consistent.

[0011] In this design, after the clamping jaws insert the wire into the terminal socket at the insertion station, the electric screw-tightening head is moved to the pre-set clamping bolt on the terminal by the second pushing part. During this process, the height of the electric screw-tightening head is finely adjusted by the second lifting part, allowing the electric screw-tightening head to align with the clamping bolt and tighten it, thus achieving automatic wire fixing. Furthermore, by placing the tightening unit directly above the clamping jaw unit, the electric screw-tightening head can align with the clamping bolt without horizontal adjustment, reducing the time spent on adjustment and effectively improving the working efficiency of the tightening unit.

[0012] Preferably, the first frame is further provided with a visual recognition module, the recognition direction of which is always towards the wiring station, for locating and recognizing the position of the clamping bolt of the terminal on the wiring station.

[0013] To ensure the accuracy of the gripper in grasping the corresponding wire, preferably, the first pushing part includes a guide rail horizontally fixed on the frame and a lead screw driven by a motor. The lead screw is provided with a nut slide that slides with the guide rail. The first lifting part is fixedly provided on the nut slide. The first lifting part includes a telescopic motor. The telescopic motor is fixed on the nut slide. The telescopic head of the telescopic motor is vertically upward and is equipped with the gripper.

[0014] Because the electric screwdriver generates a large torque when tightening the clamping bolt, in order to ensure the stable operation of the tightening unit, the second push part includes a second frame box. The two inner side walls of the second frame box are provided with horizontal slide rail structures. A tightening box is slidably arranged in the second frame box through the horizontal slide rail structures. The electric screwdriver is arranged in the tightening box. The electric screwdriver extends from one end of the tightening box, and the other end of the tightening box is fixedly connected to the push rod end of the electric push rod. The drive end of the electric push rod is fixedly arranged on the second frame box. The extension and retraction of the electric push rod controls the movement of the tightening box in the direction in which the electric screwdriver extends.

[0015] In this design, the tightening box is moved along the second frame box by an electric push rod at one end. The slide rail structure on both sides of the tightening box can evenly distribute the force in other directions, ensuring the stability of the tightening box during sliding and ensuring that the electric tightening head can be aligned with the clamping bolt. When the electric tightening head is working, the slide rail structure on both sides of the tightening box can also fully transmit the torque to the second frame box and even the frame, thus fully ensuring the stability of the tightening unit.

[0016] Preferably, the second lifting part includes a pair of guide rails vertically fixed on the first frame and a lead screw driven by a motor. The lead screw is provided with a nut slide, which is fixed on both sides of the second frame box, allowing the second frame box to slide vertically in the first frame.

[0017] Similarly, in order to improve the overall system efficiency, it is necessary to ensure timely replacement of consumables. In order to ensure the efficiency of reel replacement, the reel module includes a connecting plate at the top of the frame. The connecting plate is connected from top to bottom to a third pushing part, a rotating part and a quick-release plate. The third pushing part controls the quick-release plate to move vertically, and the rotating part controls the quick-release plate to rotate horizontally. The quick-release plate is used for detachable connection of the reel.

[0018] In this design, the self-rotating part enables the rotation of the wire reel set on the quick-release plate, while the third pushing part enables the wire reel to move vertically. The third pushing part can push the wire reel away from the insertion station by pushing the quick-release plate down, providing more operating space, and the quick-release plate enables the rapid replacement of the wire reel.

[0019] Preferably, the quick-release plate is horizontally and centrally fixedly connected to the rotating shaft of the self-rotating part, and a locking device is fixedly inserted through the quick-release plate, the locking device corresponding to the locking pin provided on the coil.

[0020] In this solution, when there is no coil loaded on the quick-release plate, align the locking device with the locking pin on the new coil to ensure that the new coil is placed on a support surface. The coil can be quickly installed simply by moving the quick-release plate down and inserting the locking pin into the locking device.

[0021] To facilitate more efficient and rapid disassembly of the reel, preferably, a pneumatic telescopic rod that extends vertically downwards is fixedly installed on the side wall of the rotating part. The rotating part drives the quick-release plate to rotate, so that the locking device is located directly below the pneumatic telescopic rod. By extending downwards and abutting against and triggering the switch of the locking device, the locking device can be released from locking the locking pin.

[0022] The beneficial effects of this invention are:

[0023] When using this invention for the wiring process of terminal blocks, the loading module loads a wire spool containing wires, the clamping unit in the clamping module picks up the wires on the spool and automatically inserts them into the terminal's wiring port, and then the tightening unit tightens the clamping bolts. The entire process requires no human intervention and can automatically and efficiently perform the wiring connection of the entire terminal block, improving production efficiency while reducing labor costs.

[0034] The coil 6 used in this invention is as follows Figure 5 As shown, the structure is a disc. Multiple slots 61 are arranged in a circular array along the edge of the disc 6. The through holes formed by the slots 61 form an opening 62 at the position of the peripheral wall of the disc 6. The opening 62 is smaller than the maximum diameter of the through hole. The wire 7 is inserted into the slot 61 in advance. The end of the wire 7 protrudes from the top of the slot 61. The diameter of the end of the wire 7 is larger than the wire body. The diameter of the end of the wire 7 is adapted to the through hole formed by the slot 61, while the diameter of the wire body is smaller than the width of the opening 62.

[0035] Example 1:

[0036] like Figure 1 An automatic insertion system for terminal blocks 5 with wires 7 is shown, comprising a frame 1, on which a mounting module 2 is mounted for placing the terminal blocks 5 to be inserted. The mounting module 2 can control the terminal blocks 5 to move along their length to sequentially position multiple terminals to preset insertion positions. A tray mounting module 3 is located on one side of the insertion positions and is used to load a tray 6 with wires 7 arranged on it. The tray 6 can be controlled to rotate by a drive mechanism so that the corresponding wires 7 are in preset clamping positions. A clamping and mounting module 4 is located on the other side of the insertion positions and includes a gripper unit 41 for clamping the ends of the wires 7 and a tightening unit 42 for tightening the clamping bolts 52 on the terminal blocks 5. A control system is connected to other modules in communication and coordinates the operation of each module.

[0037] Among them, such as Figure 1 As shown, the frame 1 includes a top beam plate 11, a support beam 12 supporting the top beam plate 11, a horizontal guide beam 13 disposed below the top beam plate 11, and a control box 14 housing the control system. The tray loading module 3 is disposed below the top beam plate 11, while the mounting module 2 includes a stepper drive component 21 and a stepper base 22. The stepper drive component 21 is mounted on the horizontal guide beam 13 and is drively connected to the stepper base 22. That is, one side of the horizontal guide beam 13 is the tray loading module 3, and the other side is the clamping and mounting module 4. The stepper base 22 is used for detachably mounting terminal blocks 5. The stepper drive component 21 drives the stepper base 22 to move along the length of the terminal blocks 5. The terminal blocks 5 are placed along the horizontal guide beam 13, with the wire insertion holes 51 of each terminal of the terminal blocks 5 facing vertically downwards. The step distance of the stepper drive 21 driving the stepper base 22 is adjusted according to the spacing between the wire insertion holes 51 between adjacent terminals of the terminal block 5, ensuring that the stepper drive 21 can quickly and efficiently place the corresponding terminal in the insertion position. Of course, the stepper base 22 does not necessarily have to be equipped with the terminal block 5; it can also be equipped with multiple individual terminals. This embodiment and the following will use the terminal block 5 as an example. Specifically, the stepper drive 21 preferably uses a lead screw and lead screw nut transmission structure. The stepper base 22 is set on the lead screw nut, and the lead screw is driven to rotate by the stepper motor, allowing the stepper base 22 to slide horizontally along the frame 1 with the terminal block 5. It should be noted that since the terminal block 5 may consist of many terminals and is relatively long, an extension slide rail 132 is additionally provided on the horizontal guide beam. A sliding block 131 is provided on the extension slide rail 132. One end of the stepper base 22 is set on the lead screw nut, and the other end is set on the sliding block 131. The stepper base 22 can be detachably connected to the terminal block 5 by means of snap-fit, magnetic attraction, bolt connection, etc.

[0038] like Figure 1 and Figure 2 As shown, the gripper unit 41 is fixedly mounted on the frame 1, including a first lifting part 411, a first pushing part 412, and a gripping claw 413. The gripping claw 413 can move horizontally linearly towards the wire insertion station via the first pushing part 412, and can also move vertically via the first lifting part 411. The gripping claw 413 is an electric gripper with two arms that can move relative to each other, and the ends of the arms are provided with gripping grooves that fit the ends of the wires 7. In this embodiment, to ensure the accuracy of the gripper in gripping the corresponding wires 7, the first pushing part 412 specifically includes a guide rail fixedly mounted horizontally on the frame 1 and a lead screw driven by a motor. The lead screw is provided with a nut slide that slides with the guide rail. The first lifting part 411 is fixedly mounted on the nut slide. The first lifting part 411 includes a telescopic motor, which is fixed on the nut slide. The telescopic head of the telescopic motor is vertically upward and the gripping claw 413 is installed at its end.

[0039] In this embodiment, when the terminal block 5 is inserted, the insertion station, the clamping station, the gripper unit 41, and the tightening unit 42 are all in the same vertical plane. That is, the insertion station and the clamping station move along the path of the gripper unit 41 in the vertical projection direction. During operation, it is only necessary to ensure that the positions of the tray module 3 and the clamping and mounting module 4 correspond to the position of the first terminal hole of the terminal block 5 in the tray module 2. Subsequent repositioning is unnecessary. As long as the positioning of the terminal block 5 controlled by the tray module 2 is accurate, the insertion accuracy of the terminal block 5 can be guaranteed, thus ensuring the reliability of the insertion quality. Figure 3As shown, the loading module 3 loads the wire spool 6 and positions the first wire 7 on the wire spool 6 at the clamping station. The first pushing part 412 pushes the clamping claw 413 toward the clamping station. The clamping claw 413 passes over the horizontal guide beam 13 from below the terminal block 5 and clamps the end of the wire 7 at the clamping station from the wire spool 6. Then, the first lifting part 411 moves to make the clamping claw 413 clamp the wire 7 and move it upward, so that the thinner wire body of the wire 7 is located in the slot 61 of the wire spool 6. Then, the first pushing part 412 drives the clamping claw 413 to retract, thereby removing the wire 7 from the wire spool 6. When the gripper 413 retracts while holding the wire 7, its movement path passes directly below the wire insertion hole 51 of the terminal at the insertion station. After the wire 7 moves to this position, the first lifting unit 411 continues to control the gripper 413 to move upward, inserting the end of the wire 7 into the guide socket of the terminal. After the tightening unit 42 locks the terminal clamping bolt 52, the gripper 413 releases the wire 7 and returns to its initial position. During the process of the gripper 413 returning to its initial position, the stepper transmission unit 21 controls the terminal block 5 to move the distance of one terminal, so that the next terminal on the terminal block 5 is in the insertion station. At the same time, the tray module 3 controls the terminal to rotate, so that the next wire 7 is in the clamping station. Then the gripper 413 in the gripper unit 41 repeats the action... until all terminals on all terminal blocks 5 have been inserted.

[0040] Example 2:

[0041] Based on Embodiment 1, this embodiment provides a specific tightening unit 42, such as... Figure 2 and Figure 4 As shown, the tightening unit 42 includes a second lifting part 421, a second pushing part 422, and an electric screwdriver head 423. The electric screwdriver head 423 is an existing electric wrench with a threaded cutter. The electric screwdriver head 423 can achieve horizontal linear movement towards the wire insertion station through the second pushing part 422. The electric screwdriver head 423 can perform vertical translation through the second lifting part 421. The pushing direction of the first pushing part 412 is the same as that of the second pushing part 422.

[0042] The rack 1 also includes a first frame 43, such as Figure 2 and Figure 4 As shown, the first frame 43 is set above the control box 14 to provide installation space for the tightening unit 42. The first frame 43 is a support plate structure surrounding the gripper unit 41. The tightening unit 42 is set on the first frame 43 to ensure that the tightening unit 42 is located directly above the gripper unit 41.

[0043] Specifically, the second pushing part 422 includes a second frame box 431. A horizontal slide rail structure 432 is provided on the two inner side walls and / or inner bottom of the second frame box 431. A tightening box 433 is slidably disposed in the second frame box 431 via the horizontal slide rail structure 432. An electric tightening head 423 is disposed in the tightening box 433. The electric tightening head 423 extends from one end of the tightening box 433, and the other end of the tightening box 433 is fixedly connected to the push rod end of an electric push rod 434. The drive end of the electric push rod 434 is fixedly disposed on the second frame box 431. The electric push rod 434 extends and retracts, pushing... The tightening box 433 moves along the horizontal slide rail structure 432 in the direction in which the electric screw head 423 extends. Of course, in order to prevent the electric screw head 423 from rigidly colliding with the terminal block, a compression spring (not shown in the figure) is preferably provided between the electric push rod 434 and the tightening box 433. That is, the compression spring is sleeved on the push rod shaft of the electric push rod 434, with one end abutting the drive end of the electric push rod and the other end abutting the tightening box 433. The push rod shaft of the electric push rod 434 slides into the tightening box 433, and an anti-disengagement pin is provided at the end to prevent the push rod shaft of the electric push rod 434 from coming out of the tightening box 433. The electric push rod 434 and the tightening box 433 are flexibly connected. When the electric push rod 434 pushes the tightening box 433 towards the tightening box 433, the compression spring is compressed. The tightening box 433 will only move when the compression spring exerts sufficient force on it. When the electric screw head 423 deviates from its accuracy, it moves and contacts the terminal block 5. The compression spring can be further compressed, which plays a buffering role and prevents rigid collisions, thus avoiding damage or scratches to the terminal block 5.

[0044] Furthermore, since multiple clamping bolts 52 for different terminals are generally arranged along the insertion direction of the wire 7, and the spacing between clamping bolts 52 is different for different terminals, the electric screw head 423 is raised and lowered by the second lifting part 421 to accommodate clamping bolts 52 of different heights. Specifically, the second lifting part 421 includes a pair of guide rails vertically fixed on the first frame 43 and a lead screw driven by a motor. The lead screw is provided with a nut slide, which is fixed on both sides of the second frame box 431, allowing the second frame box 431 to slide vertically in the first frame 43. The lead screw on the first frame 43 rotates synchronously, thereby controlling the vertical movement of the second frame box 431.

[0045] Furthermore, the electric screwdriver head 423 also integrates a torque sensor, which is used to monitor the torque of the electric screwdriver head 423. When the torque sensor detects that the torque exceeds the set threshold, it can be determined that the tightening bolt 52 has been tightened to the correct position. The torque sensor transmits the signal to the control system, which then controls it to stop tightening and retract.

[0046] In this embodiment, after the clamping claw 413 in the clamping unit inserts the wire 7 into the wire socket 51 of the terminal at the insertion station, the electric rotating head 423 is height-controlled by the second lifting part 421 to align it with the lowest clamping bolt 52. Then, the second pushing part 422 actuates, moving the electric rotating head 423 toward the clamping bolt 52 and engaging with it. The electric rotating head 423 then rotates to tighten the clamping bolt 52. After tightening one clamping bolt 52 of the terminal, the second pushing part 422 retracts the electric rotating head 423. Then, the second lifting part 421 controls the electric rotating head 423 to adjust its height to align with the next clamping bolt 52, and the second pushing part 422 brings it into contact with the clamping bolt 52... until all clamping bolts 52 of the terminal are tightened, the electric rotating head 423 retracts to its initial position.

[0047] It should be noted that a visual recognition module can also be set on the first frame 43. The visual recognition module can use existing visual cameras, etc., and is connected to the control system. Its recognition direction is always towards the insertion station, which is used to locate and identify the position of the clamping bolt 52 of the terminal on the insertion station, so as to ensure the reliability of the electric screw head 423 in locking the clamping bolt 52.

[0048] Example 3:

[0049] To improve the overall system efficiency, timely replacement of consumables is also necessary. To ensure the efficiency of coil 6 replacement, this embodiment, based on the above embodiments, provides a specific coil mounting module 3 structure, such as... Figure 2 and Figure 5 As shown, the tray loading module 3 includes a connecting plate 31 at the top of the frame 1. The connecting plate 31 is mounted on the top beam plate 11 of the frame 1. From top to bottom, the connecting plate 31 is connected to a third pushing part 32, a rotating part 33, and a quick-release plate 34. In this embodiment, a linear drive part 35 is provided below the top beam plate 11, and the connecting plate 31 is mounted on the linear drive part 35, thereby enabling the tray loading module 3 to perform horizontal displacement. The linear drive part 35 can use existing transmission structures, such as a motor-driven screw-nut-slider mechanism or a motor-driven gear and rack structure. The third pushing part 32 is an existing telescopic cylinder, which controls the quick-release plate 34 to move in the vertical direction. The self-rotating part 33 is a stepper motor that is communicatively connected to the control system. The motor base 36 of the stepper motor is a frame structure that encloses the stepper motor. The bottom of the motor base 36 is fixedly connected to the connecting plate 31. The output shaft of the stepper motor extends downward from the motor base 36 and is fixedly connected to the quick-release plate 34. The rotation of the stepper motor controls the quick-release plate 34 to rotate horizontally around the center. The quick-release plate 34 is used to detachably connect the cable reel 6.

[0050] Specifically, the quick-release plate 34 is horizontally and centrally fixedly connected to the rotating shaft of the self-rotating part 33. A locking device 341 is fixedly inserted on the quick-release plate 34. Preferably, two locking devices 341 are symmetrically arranged around the center of rotation. A locking pin is also fixedly installed on the coil 6 so that the locking device 341 corresponds to the locking pin on the coil 6.

[0051] When the quick-release plate 34 is not loaded with a coil 6, align the locking device 341 with the locking pin on the new coil 6 to ensure the new coil 6 is placed on a support surface. Simply lower the quick-release plate 34 to allow the locking pin to insert into the locking device 341 for quick installation of the coil 6. The rotating part 33 has a pneumatic telescopic rod 342 fixedly mounted on its side wall, extending vertically downwards. The telescopic cylinder is communicatively connected to the control system. When unloading the coil 6, the rotating part 33 drives the quick-release plate 34 to rotate, positioning the locking device 341 directly below the pneumatic telescopic rod 342. The pneumatic telescopic rod 342 extends downwards and abuts against and triggers the switch of the locking device 341, releasing the locking device 341 from the locking pin. The coil 6 then falls naturally under gravity, achieving quick unloading of the coil 6.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
