Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of terminal row wiring device, and particularly provides an automatic wiring system for wire terminals. BACKGROUND

[0002] In the field of electrical wiring, wire terminals (such as terminal blocks, terminal rows, etc.) are widely used to achieve reliable connection between wires and devices. The traditional or current mainstream wiring method mainly relies on manual operation, that is, the worker manually inserts the exposed end of the wire into the terminal hole, and then uses a screwdriver or other tool to tighten the compression screw on the terminal, thereby completing the fixation.

[0003] In the scenario requiring large-scale and high-density wiring (such as the production of control cabinets, switchboards, communication equipment, etc.), the existing terminal row wiring mode often has problems such as low efficiency, especially in the repeated manual wiring process, the wiring precision is too low to ensure that all terminals can be aligned at one time. Therefore, the wire often needs to be aligned and inserted into the hole multiple times, which affects the wiring efficiency, and the end of the wire collides with the bottom of the terminal multiple times, which is easy to scratch the terminal row or bend the wire, thereby causing poor consistency of the terminals of the terminal row and affecting the wiring quality of the entire electrical system. SUMMARY

[0004] To solve the above problems, the present application aims to provide a device that realizes full automation from cable grabbing, precise positioning, insertion into the terminal to final tightening, saving labor costs and improving production efficiency.

[0005] The technical scheme of the present application is as follows:

[0006] An automatic wiring system for wire terminal rows includes a rack, a terminal row loading module is arranged on the rack, the terminal row loading module is used to place a terminal row to be wired, and the terminal row loading module can control the terminal row to move along its length direction to position a plurality of terminals to a preset wiring station in turn; a disc loading module is located on one side of the wiring station, used to load a wire disc with wires arranged thereon, and can control the wire disc to rotate through a driving mechanism so that the corresponding wire is in a preset clamping station; a clamping and mounting module is located on the other side of the wiring station, the clamping and mounting module includes a clamping jaw unit for clamping the end of the wire and a tightening unit for tightening the compression screw on the terminal row; a control system is in communication connection with the terminal row loading module, the disc loading module and the clamping and mounting module, and coordinates the actions of each module. When the terminal row performs the wiring action, the wiring station, the clamping station, the clamping jaw unit and the tightening unit are in the same vertical plane.

[0007] In this scheme, unlike the existing manual insertion, the control system in the application controls the coordinated work of each module. The disc loading module loads the wire disc provided with wires, the clamping jaw unit in the clamping installation module clamps the wires on the wire disc, and automatically inserts them into the terminal wire insertion port. Then, the tightening unit is tightened, and the whole process does not need manual intervention, which can complete the wire insertion action of a terminal. By controlling the rotation angle of the disc loading module, the corresponding wire can be rotated to the clamping position of the clamping jaw unit. The wire insertion position, the clamping position, the clamping jaw unit and the tightening unit are in the same vertical plane. Only the positions of the wire insertion position and the standby clamping position need to be fixed. The clamping unit can accurately clamp and precisely insert the wire without moving too much. Subsequent positioning is not required, thereby realizing high-precision positioning and rapid insertion of the wire.

[0008] Preferably, the clamping jaw unit is fixedly arranged on the rack and includes a first lifting part, a first pushing part and a clamping jaw. The clamping jaw can move horizontally linearly towards the wire insertion position through the first pushing part. The clamping jaw can move vertically through the first lifting part.

[0009] In this scheme, the clamping jaw can quickly clamp the wire. By clamping the end of the wire, the wire end is inserted into the terminal and then quickly separated from the wire and reset. Since the positions of the wire insertion position and the standby clamping position are fixed, the clamping jaw of the clamping jaw unit only needs to move vertically and vertically, without complex action instructions and driving structures, which can effectively reduce the programming difficulty and production difficulty of the components.

[0010] Preferably, the clamping installation module further includes a first frame arranged on the rack. The tightening unit is arranged on the first frame. The tightening unit is located directly above the clamping jaw unit. The tightening unit includes a second lifting part, a second pushing part and an electric screwing head. The electric screwing head can move horizontally linearly towards the wire insertion position through the second pushing part. The electric screwing head moves vertically through the second lifting part. The pushing directions of the first pushing part and the second pushing part are consistent.

[0011] In this scheme, after the clamping jaw inserts the wire into the terminal hole of the terminal on the wire insertion position, the electric screwing head moves to the preset compression screw of the terminal through the second pushing part. During this period, the height of the electric screwing head is adjusted through the second lifting part, so that the electric screwing head can be aligned with the compression screw and rotated and tightened, thereby realizing automatic fixing of the wire. By arranging the tightening unit directly above the clamping jaw unit, the electric screwing head can be aligned with the compression screw without horizontal adjustment, which reduces the time consumption of positioning and effectively improves the working efficiency of the tightening unit.

[0012] Preferably, the first frame is also provided with a visual identification module, the identification direction of the visual identification module is always towards the terminal inserting station, and the visual identification module is used for positioning and identifying the compression bolt position of the terminal on the terminal inserting station.

[0014] Since the electric screwdriver generates a large torque when tightening the compression bolt, in order to ensure the stability of the tightening unit in operation, the second pushing part comprises a second frame box, horizontal sliding rail structures are arranged on the two inner side walls of the second frame box, a tightening box is slidingly arranged in the second frame box through the horizontal sliding rail structures, the electric screwdriver is arranged in the tightening box, the electric screwdriver extends from one end of the tightening box, the other end of the tightening box is fixedly connected with the push rod end of an electric push rod, the driving end of the electric push rod is fixedly arranged on the second frame box, and the electric push rod is telescopic to control the movement of the tightening box in the direction in which the electric screwdriver extends.

[0015] In this scheme, the tightening box is pushed to move along the second frame box by the electric push rod at one end, the sliding rail structures on the two sides of the tightening box can evenly share the force in other directions, so as to ensure the stability of the tightening box in sliding, ensure that the electric screwdriver can be aligned with the compression bolt, and when the electric screwdriver works, the sliding rail structures on the two sides of the tightening box can also fully transmit the torque to the second frame box and even the rack, so as to fully ensure the stability of the tightening unit.

[0016] Preferably, the second lifting part comprises a pair of guide rails fixed vertically on the first frame and a lead screw driven by a motor, the lead screw is provided with a nut sliding table, and the nut sliding table is fixed on the two sides of the second frame box, so that the second frame box is vertically slidingly arranged in the first frame.

[0017] In order to ensure that the consumables are replaced in time, in order to improve the efficiency of the whole system, in order to ensure the replacement efficiency of the wire disc, the disc mounting module comprises a connecting plate at the top end of the rack, the connecting plate is sequentially connected from top to bottom with a third pushing part, a self-rotation part and a quick mounting plate, the third pushing part controls the vertical movement of the quick mounting plate, the self-rotation part controls the horizontal rotation of the quick mounting plate, and the quick mounting plate is used for detachably connecting the wire disc.

[0018] In the scheme, the rotating part realizes the rotating action of the wire coil arranged on the quick mounting plate, and the third pushing part realizes the translation of the wire coil in the vertical direction, the third pushing part pushes the wire coil away from the wire insertion station by pushing down the quick mounting plate, so as to provide more operation space, and the quick mounting plate realizes the quick replacement of the wire coil.

[0019] Preferably, the horizontal center of the quick mounting plate is fixedly connected to the rotating shaft of the rotating part, and a locking device is fixedly arranged through the quick mounting plate, and the locking device corresponds to the locking pin arranged on the wire coil.

[0020] In the scheme, when the quick mounting plate is not loaded with the wire coil, the locking device is aligned with the locking pin on the new wire coil, and the new wire coil is placed on a supporting surface, and the quick mounting plate is only needed to be lowered to insert the locking pin into the locking device to realize the quick installation of the wire coil.

[0021] In order to more efficiently and quickly disassemble the wire coil, preferably, the sidewall of the rotating part is fixedly provided with a pneumatic telescopic rod which can vertically extend downward, the rotating part drives the quick mounting plate to rotate, so that the locking device is located directly below the pneumatic telescopic rod, and the locking device is unlocked by the pneumatic telescopic rod extending downward and abutting and triggering the switch of the locking device.

[0022] The beneficial effects of the present application are as follows:

[0035] Embodiment one:

[0036] As Figure 1 shown in one kind of automatic insertion system of terminal row 5 of wire 7, including rack 1, rack 1 is provided with dress row module 2, dress row module 2 is used to place the terminal row 5 to be inserted wire, dress row module 2 can control terminal row 5 along its length direction moves, to make multiple terminals be positioned to preset wire insertion station in turn;Dress disc module 3, dress disc module 3 is located at one side of wire insertion station, is used to load the wire disc 6 that is laid with wire 7, and can be rotated by drive mechanism control wire disc 6, make corresponding wire 7 be in preset clamping station;Clamping installation module 4, clamping installation module 4 is located at the other side of wire insertion station, clamping installation module 4 includes the clamping jaw unit 41 for clamping the end of wire 7 and the tightening unit 42 for tightening the terminal row 5 on the compression bolt 52;Control system, control system is connected with other module communication and coordinates the action of each module.

[0037] As Figure 1 shown, rack 1 includes roof beam plate 11, support roof beam plate 11's support beam 12, setting horizontal guide beam 13 under roof beam plate 11 and the control box 14 of placing control system. Wherein, dress disc module 3 is set under roof beam plate 11, and dress row module 2 includes step drive part 21 and step base 22, step drive part 21 is set on the horizontal guide beam 13, and is transmissionally connected with step base 22. That is, one side of horizontal guide beam 13 is dress disc module 3, and the other side is clamping installation module 4. Step base 22 is used for detachable installation terminal row 5, and step drive part 21 is used for driving step base 22 to move along the length direction of terminal row 5, terminal row 5 is placed along horizontal guide beam 13, and makes the wire insertion hole 51 of each terminal of terminal row 5 vertically downward. According to the pitch between wire insertion hole 51 between adjacent terminals of terminal row 5, the step distance of step base 22 movement driven by step drive part 21 is adjusted, to ensure that step drive part 21 acts, and can quickly and efficiently make the corresponding terminal be in wire insertion station, of course, step base 22 is not necessarily provided with terminal row 5, but also can be provided with multiple individual terminals, this embodiment and subsequent are all taken as setting terminal row 5. Specifically, step drive part 21 preferably uses screw rod and screw rod nut transmission structure, step base 22 is set on screw rod nut, and step motor is used for driving screw rod to rotate, so that step base 22 carries terminal row 5 and slides along rack 1. It needs to be explained that, since terminal row 5 can be composed of more terminals, and the length is relatively long, an extension slide rail 132 is additionally provided on the horizontal guide beam, the extension slide rail 132 is provided with a sliding block 131, one end of the step base 22 is provided on the screw rod nut, and the other end is provided on the sliding block 131. Step base 22 is detachably connected with terminal row 5 by clamping, magnetic attraction, bolt connection and the like.

[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.
