DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0020] The specific implementation modes of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] Reference Figure 1-9. An embodiment of the present invention provides a circuit board broken wire repair device, wherein the circuit board broken wire repair device includes a device body 100, the device body 100 is placed on the ground, and is used to repair the broken wire of the circuit board, wherein a processing platform 200 is fixedly arranged on the device body 100, and its fixing method can be bonding, clamping or bolting, etc. In this embodiment, the processing platform 200 is selected to be fixedly arranged on the device body 100 by bolting, and the processing platform 200 is used to place the circuit board; at the same time, a welding head 300 is arranged on the device body 100, and the welding head 300 is connected to the circuit, and is used to heat and weld the circuit on the circuit board. The principle of the resistance welding machine can be referred to, and it will not be repeated here. In this embodiment, the welding head 300 can move in the vertical direction, and the welding head 300 is arranged relative to the processing platform 200, so that the welding head 300 can approach or move away from the processing platform 200 during the movement, so as to weld and repair the circuit board. In order to facilitate welding and repair at both ends of the line, two welding heads 300 are set.

[0022] Reference Figure 1-9 The circuit board wire breakage repair device also includes a receiving portion 400, each receiving portion 400 corresponds to a welding head 300, and the receiving portion 400 includes two receiving members 410 arranged opposite to each other, and the receiving member 410 is movably arranged at the end of the welding head 300. Specifically, in this embodiment, the receiving member 410 is rotatably arranged at the end of the welding head 300, and a receiving groove 420 is arranged on the receiving member 410, and the receiving groove 420 is used to place and clamp the solder; at the same time, the circuit board wire breakage repair device also includes a loading unit 500, which is also arranged on the device body 100, and the loading unit 500 is used to transfer the solder. To the receiving groove 420, in the working state, the loading unit 500 transfers the solder to the receiving groove 420, and the receiving grooves 420 of the two receiving parts 410 jointly clamp the solder. After the solder clamping is completed, the welding head 300 moves toward the technician platform, and the relatively arranged receiving parts 410 contact the circuit board. Under the push of the circuit board, the relatively arranged receiving parts 410 move in directions away from each other, so that the solder contacts the circuit board. At this time, one end of the solder contacts the circuit board, and the other end contacts the welding head 300, and the solder is just in the place to be repaired. The welding head 300 is powered on and started to weld the solder at the place to be repaired, thereby repairing the circuit board.

[0023] Reference Figure 1-9, wherein a connecting tube 460 is provided on the side wall of the welding head 300 by rotating through a rotating shaft, the connecting tube 460 is rectangular, and the end of the connecting tube 460 away from the welding head 300 is open, and the receiving member 410 is fixedly provided inside the connecting tube 460 by means of a clamping method, wherein a receiving plate 430 is fixedly provided on the side wall of the receiving member 410, and the fixing method thereof may be bonding, welding or integral molding, etc. In the present embodiment, a receiving plate 430 is selected to be fixedly provided on the receiving member 410 by means of an integral molding method, and a protrusion is formed on the receiving member 410, and at the same time, the receiving plates 430 on the two receiving members 410 arranged opposite to each other contact each other, and the receiving member 410 and the receiving plate 430 jointly form a receiving groove 420 for placing solder.

[0024] At the same time, a splash plate 440 is fixedly provided on the side wall of the receiving part 410, and the fixing method thereof may be bonding, welding or integral molding, etc. In the present embodiment, the splash plate 440 is selected to be fixedly provided on the receiving plate 430 by integral molding, so that there is a gap between the splash plate 440 and the side wall of the receiving part 410, and at the same time, the splash plate 440 covers the side wall of the connecting tube 460, that is, after the receiving part 410 is connected to the connecting tube 460, one side wall of the connecting tube 460 is placed between the splash plate 440 and the side wall of the receiving part 410.

[0025] At the same time, a glass fiber cloth 450 is fixedly provided at the end of the splash plate 440, and the fixing method thereof can be bonding, clamping or bolting, etc. In the present embodiment, the two are fixedly connected by bolting, and at the same time, the glass fiber cloth 450 covers the rotating shaft of the connecting tube 460. The splash plate 440 cooperates with the glass fiber cloth 450, so that the splashing welding slag generated during the welding process will not splash onto the rotating shaft of the connecting tube 460, thereby not affecting the rotation of the connecting tube 460.

[0026] In this embodiment, the connecting tube 460 can be directly rotatably set on the welding head 300, or an additional connecting plate 470 can be added. The connecting plate 470 is fixedly connected to the equipment body 100 by bolts and can move synchronously with the welding head 300; the connecting tube 460 is rotatably connected to the connecting plate 470. Since the temperature of the welding head 300 is high during operation, when the connecting tube 460 is directly rotatably set on the welding head 300, the material of the connecting tube 460 is the same as that of the welding head 300, thereby minimizing the possibility of damage to the connecting tube 460. In this embodiment, an additional connecting plate 470 is selected, and the connecting tube 460 is rotatably connected to the connecting plate 470. At the same time, the shape of the connecting plate 470 is the same as that of the welding head 300, and there is a gap between the connecting plate 470 and the side wall of the welding head 300, thereby minimizing the possibility of damage to the connecting tube 460.

[0027] In addition, a control surface is provided at the end of the receiving member 410. Specifically, the control surface is provided at the end surface of the receiving member 410 away from the welding head 300, and the control surfaces on the relatively arranged receiving members 410 are inclined and move away from each other in the direction toward the processing platform 200. During operation, the solder is placed in the receiving groove 420, and the movement of the welding head 300 drives the movement of the solder. When the receiving member 410 contacts the circuit board, under the action of the inclined control surface, the relatively arranged receiving members 410 move in the direction away from each other. Movement, and when the receiving plate 430 contacts the circuit board, the gap between the two relatively arranged receiving plates 430 is just enough for the solder to pass through, so that the solder is placed at the place to be welded, and the welding head 300 continues to move and abuts against the solder, thereby performing the repair work. At the same time, in order to facilitate the movement of the receiving part 410, the control surface is arranged in an arc shape, so that the process of the circuit board pushing the receiving part 410 is gentle, reducing the possibility of damaging the circuit board. Similarly, an arc-shaped guide surface is provided on the receiving plate 430, which further reduces the possibility of damaging the circuit board.

[0028] Reference Figure 1-9 The loading unit 500 includes a loading block 510, a cutting piece 520 and a placing piece 530; wherein the loading block 510 is fixedly arranged on the equipment body 100, and its fixing method can be bonding, welding or bolt fixing, etc. In this embodiment, the loading block 510 is fixedly arranged on the equipment body 100 by bolt fixing, and a loading hole 540 is opened on the loading block 510, and the loading hole 540 is connected to the receiving groove 420.

[0029] Specifically, a loading trough is provided on the loading block 510, and the loading trough is used to place solder. One end of the loading hole 540 is connected to the loading trough, and the other end is connected to the outside of the loading block 510. When the welding head 300 is placed in the initial position, that is, the welding head 300 is placed in the fixed position farthest from the processing platform 200, the loading hole 540 is connected to the receiving groove 420, so as to facilitate the transfer of the solder to the receiving groove 420. In this embodiment, the solder is selected as welding wire, and a placement piece 530 is rotatably arranged in the loading trough. The welding wire is wound on the placement piece 530, and a motor is fixedly arranged at the bottom of the loading trough by bolts. The shaft key of the motor is connected to the placement piece 530, which is used to drive the placement piece 530 to rotate, so that the welding wire is transferred from the loading hole 540 to the receiving groove 420.

[0030] The cutting piece 520 is fixedly arranged on the inner wall of the feeding hole 540 and is placed at one end connected to the receiving groove 420. The fixing method can be selected from bonding, welding or integrated molding. In the present embodiment, the two are fixed by welding. The cutting piece 520 is annular and has a cutting end 521. The cutting end 521 is the inner edge of the cutting piece 520. At the same time, the side wall of the feeding block 510 abuts against the side wall of the welding head 300. At the same time, the inner wall of the feeding hole 540 is fixedly provided with a transition piece 550 to facilitate the movement of the solder to the cutting end 521, thereby reducing the possibility that the solder is blocked by the cutting piece 520. During operation, the welding wire enters the receiving groove 420 through the feeding hole 540. At this time, the welding head 300 moves. Under the action of the cutting piece 520, the welding wire contacts the cutting end 521, the welding wire is cut, the welding wire body is separated, and a part of the welding wire is placed in the receiving groove 420 and moves synchronously with the welding head 300.

[0031] Reference Figure 1-9 The circuit board broken wire repairing device also includes a transport component, wherein the transport component includes a transport plate 610, a detection component 620 and a control system. The transport plate 610 is movably arranged on the processing platform 200. Specifically, a driving member 630 is rotatably arranged on the processing platform 200 through a rotating shaft. The driving member 630 is in a long strip shape, and one end of the long strip driving member 630 is rotatably arranged on the processing platform 200. A motor is fixedly arranged at the bottom of the processing platform 200 by bolts. The rotating shaft key of the motor is connected to the driving member 630, which is used to drive the driving member 630 to rotate on the processing platform 200. A driving groove 640 is opened on the driving member 630. The length direction of the driving groove 640 is the same as the length direction of the driving member 630, and the transport plate 610 is rotatably arranged in the driving groove 640 and can move in the driving groove 640.

[0032] Specifically, the transport plate 610 can move in the driving groove 640 along the length direction of the driving groove 640, and the transport plate 610 can rotate at the same time, and its rotation is realized by a motor, which will not be elaborated here. The circuit board is placed on the transport plate 610, and the transport plate 610 drives the circuit board to be transported to any position of the processing platform 200, and the orientation of the circuit board can be adjusted by the rotation of the transport plate 610 to facilitate the repair process.

[0033] The device body 100 is provided with a conveyor belt 900, which is used to convey the circuit board. At the same time, the device body 100 is provided with a manipulator, which is used to transfer the circuit board to the transport tray 610. In the initial state, the transport tray 610 is placed at one end of the conveyor belt 900. After the circuit board is transferred to the transport tray 610, the disconnection position is detected. The detection member 620 is provided on the device body 100, which is used to detect the disconnection position of the circuit board. There are multiple detection members 620, and the multiple detection members 620 are arranged side by side on the line. The detection component 620 includes two detection probes 621 and a measuring circuit 622. The detection probes 621 are electrically connected to the measuring circuit 622. Meanwhile, the measuring circuit 622 is electrically connected to the control system. The control system is used to receive the detection signal of the detection component 620, thereby controlling the position of the transport plate 610, rotating or adjusting the position of the transport plate 610, and moving the circuit board to the welding head 300. The broken wire position of the circuit board is on the same vertical path as the welding head 300.

[0034] In addition, the two ends of the broken wire position correspond to the positions of the two welding heads 300 respectively, which facilitates the repair process; wherein, the measuring circuit 622 includes a power supply 625, a first resistor 623, and a second resistor 624, wherein one detection probe 621, a power supply 625, a second resistor 624 and another detection probe 621 are connected in series in sequence, and the first resistor 623 is connected in parallel between the power supply 625 and the second resistor 624, thereby forming a detection circuit. The specific principle refers to the multimeter and will not be repeated here. During operation, the detection probe 621 contacts the circuit of the circuit board to detect whether the circuit is normal, thereby detecting the broken wire position of the circuit board. After the detection is completed, the control system controls the movement of the transport plate 610, so that the circuit board moves to a suitable position for repair.

[0035] Reference Figure 1-9 A clamping assembly 700 is provided on the transport plate 610, and the clamping assembly 700 is symmetrically arranged on the transport plate 610, and there is a gap between the clamping assembly 700 and the transport plate 610, so as to facilitate clamping of the circuit board, wherein the clamping assembly 700 includes a fixing member 710, a clamping member 740 and an elastic member 750, wherein the fixing member 710 is fixedly arranged on the transport plate 610, and its fixing method may be bonding, welding or bolt fixing, etc. In this embodiment, the fixing member 710 is selected to be fixedly arranged on the end face of the transport plate 610 by bolt fixing, and two limit plates 720 are fixedly arranged on the fixing member 710, and its fixing method may be bonding, welding or one-piece molding, etc.

[0036] In this embodiment, the two are fixed by integral molding, and there is a gap between the two limit plates 720. At the same time, an offset groove 730 is provided on the limit plate 720, and the offset groove 730 is placed at the bottom of the limit plate 720, and the side wall of the offset groove 730 is inclined, and it gradually inclines along the direction close to the side wall of the fixing member 710 toward the direction close to the end face of the transport plate 610; the clamping member 740 is block-shaped, and the clamping member 740 is movably arranged on the limit plate 720, and can rise or fall on the limit plate 720 in a vertical direction. During its descent, the clamping member 740 contacts the circuit board, thereby clamping the circuit board; the elastic member 750 is selected as a spring, one end of the elastic member 750 is arranged on the side wall of the fixing member 710, and the other end is fixedly arranged on the side wall of the clamping member 740 by a snap-fitting manner.

[0037] Specifically, a moving groove 780 is provided on the side wall of the fixing member 710 placed between the two limit plates 720, and a moving plate 790 is slidably arranged in the moving groove 780. The moving plate 790 can slide in the moving groove 780 along the vertical direction, and a spring is fixed to the moving plate 790 by a snap-fitting manner, so that the spring is connected to the fixing member 710. Such a configuration facilitates the spring to always provide a force for the clamping member 740 to move toward the fixing member 710 during the sliding process of the clamping member 740, and when the clamping member 740 does not enter between the offset grooves 730, the elastic member 750 is in an extended state, and the elastic member 750 provides a force to the clamping member 740 to drive the clamping member 740 to move toward the fixing member 710.

[0038] During operation, the clamping member 740 slides on the limiting plate 720 to approach or move away from the circuit board. When it approaches the circuit board, it first passes through the dislocation groove 730. When it passes through the dislocation groove 730, the elastic member 750 changes from an extended state to a contracted state, and drives the clamping member 740 to move toward the dislocation groove 730. Since the side wall of the dislocation groove 730 is inclined, the clamping member 740 continues to move toward the circuit board while moving toward the dislocation groove 730 until it contacts the circuit board. From contact to clamping, the clamping member 740 still has a tendency to move toward the fixing member 710. When the clamping member 740 is fully clamped, the clamping member 740 stops moving to complete the fixation of the circuit board. This arrangement is convenient for fixing rigid circuit boards and flexible circuit boards. When the circuit board to be repaired is a flexible circuit board, the clamping member 740 can also pull the flexible circuit board to move during the process from contact to clamping, so that the flexible circuit board is in an extended state, which is convenient for the repair process. It is worth noting that the extended state here is the stretched state of the spring.

[0039] Reference Figure 1-9, a cylinder is also fixedly arranged on the fixing member 710, and the fixing method thereof can be bonding, clamping or bolting, etc. In the present embodiment, it is preferred that the cylinder is fixedly arranged on the top of the fixing member 710 by bolting, wherein the piston rod of the cylinder is slidably arranged on the clamping member 740. Specifically, a mounting groove 760 is provided on the clamping member 740, and a mounting plate 770 is arranged in the mounting groove 760. The length of the mounting plate 770 is greater than the length of the mounting groove 760, so that the clamping member 740 as a whole can move along the length direction of the mounting plate 770, that is, approach or move away from the fixing member 710; the piston rod of the cylinder is fixedly arranged on the end face of the mounting block by bolting, so that the piston rod of the cylinder is slidably arranged on the clamping member 740. During the process, the cylinder is started to drive the clamping member 740 to move in the vertical direction. At the same time, since the piston rod of the cylinder is slidably arranged on the clamping member 740, the cylinder will not interfere with the movement of the clamping member 740 in the horizontal direction, which is convenient for clamping the circuit board and tightening the flexible circuit board.

[0040] Reference Figure 1-9 The circuit board broken wire repairing device also includes a cleaning head 800, which is slidably arranged on the device body 100 in the vertical direction, wherein the cleaning head 800 has bristles, and the device body 100 is slidably arranged with a motor, which is used to drive the cleaning head 800 to rotate. During operation, after the circuit board passes the circuit break detection on the transport tray 610, the transport tray 610 rotates so that the circuit board is in a suitable direction. At this time, the cleaning head 800 descends to clean the part to be repaired, thereby ensuring the cleanliness of the welding part; in addition, the circuit board broken wire repairing device also includes a grounding circuit, one end of the grounding circuit is connected to the processing platform 200, and the other end is connected to the ground, thereby ensuring that the processing platform 200 is well grounded, thereby reducing the influence of static electricity on the circuit board, and facilitating the circuit board repair process.

[0041] The implementation principle of the circuit board broken wire repairing device of the embodiment of the present application is as follows: a broken circuit board is placed on a conveyor belt 900, the conveyor belt 900 conveys the circuit board into the device body 100, and the circuit board is transferred to the transport plate 610 by a manipulator. During the transfer process, the manipulator drives the circuit board to be placed on the transport plate 610 from between the dislocation grooves 730, and the circuit board is clamped by the clamping member 740 on the transport plate 610. The detection probe 621 detects the broken circuit position on the circuit board. During the detection process, the control system controls the transport plate 610 to adjust the position in real time. The area to be repaired of the circuit board on the transport plate 610 is made to correspond exactly to the positions of the two welding heads 300. At this time, the cleaning head 800 cleans the area to be repaired. After cleaning, the transport plate 610 drives the circuit board to move so that the area to be soldered is aligned with the welding head 300 in the vertical direction.
