Description

Technical Field

[0001] The invention relates to the technical field of automobile circuit boards, and in particular to a pin repair device for welding automobile circuit boards. Background Art

[0002] In the early stages of automobile development, the electronic equipment of automobiles was very limited. It was mainly some simple electrical systems, such as generators, spark plugs and other basic ignition devices. At that time, there were no circuit boards in the modern sense, and circuit connections were mostly made by directly connecting various electrical components through wires.

[0003] For the current repair equipment, the patent number "CN111315202B" discloses an existing pin repair equipment for automobile circuit board welding. The circuit board to be processed is inserted into the V-shaped receiving groove of two clamps. The V-shaped receiving groove is set to correct and clamp the circuit board when the two clamps move relative to each other. By starting the first motor, the first motor drives the turntable to rotate, and the turntable drives, one end of each connecting rod rotates along the axis of the turntable, and the other end of each connecting rod drives the clamp to move horizontally along each first slide rail, so that the two clamps move toward each other until the processed circuit board is clamped. This equipment drives the two clamps to clamp the circuit board through the first motor, and then drives the cutter to move down through the hydraulic cylinder to cut off the excess pins on the circuit board. However, when this equipment is used to repair multiple circuit board pins, the staff needs to frequently install the automobile circuit board alternately between the two clamps. After the repair work is completed, they have to be disassembled one by one, and then replaced with the next automobile circuit board to continue working. Such repetitive installation and disassembly operations not only seriously slow down the repair process and reduce the overall work efficiency, but also greatly increase the operating burden and labor intensity of the staff. Accordingly, the present application proposes an invention content of a pin repair device for automobile circuit board welding. Summary of the invention

[0073] 1. Through the drive assembly and the clamping assembly, start the first motor to drive the reciprocating screw to rotate, drive the screw nut and the connecting rod to slide along the groove, make the first roller move in the long board, drive the clamping plate to move synchronously, and during the movement, the first roller drives the double-headed screw to rotate, and the nut and the clamping plate clamp the circuit board to prevent sliding. After the repair is completed, the reciprocating screw with the clamping plate is reset, the first roller causes the double-headed screw to reverse, and the clamping plate is separated to release the circuit board. When repairing multiple circuit boards, there is no need to manually remove the repaired and fixed circuit boards to be repaired, which effectively reduces the labor intensity.

[0074] 2. By picking up the assembly, when the clamping plate is resetting, the second roller drives the spur rack to move through the fixed rod and meshes with the spur gear. The spur gear rotates under force and drives the support rod to rotate to the top of the clamping plate. The hydraulic rod and the electric telescopic rod are controlled by the displacement sensor to clamp the circuit board. When the clamping plate moves again, the spur rack meshes with the spur gear again, causing the support rod to rotate to the top of the finished product collection box. The displacement sensor sends a signal again and controls the hydraulic rod and the electric telescopic rod to place the repaired circuit board into the finished product placement box.

[0075] 3. By setting up the air blowing assembly, the third motor is started to drive the threaded rod to rotate, so that the sliding block and the protective cover move down to the top of the clamping plate. When the sliding block slides down, the toothed plate drives the planetary gear to rotate, and the round rod and connecting rod on the top rotate accordingly, so that the piston rod moves back and forth in the connecting pipe, and the air is transported to the nozzle through the air pipe, blowing the circuit board debris into the through groove to prevent the debris from being retained.

[0076] 4. Set up the swing assembly, start the cylinder to push the gear rod to mesh with the driving gear, thereby driving the meshing wheel and the driven gear to rotate at the same time, so that the two plug rods rotate at the same time, driving the brush roller and the brush head to swing and sweep, sweeping the excess pins into the collection box to prevent pin residue.

The clamping plate 5 is rotatably connected to the rotating shaft 401. The front end of the workbench 1 is fixedly connected with a connecting frame 8, the top surface of the workbench 1 is fixedly connected with a supporting frame 9, and the bottom surface of the supporting frame 9 is fixedly connected with a hydraulic push rod 10. The hydraulic push rod The output end of the rod 10 is fixedly connected to a support block 11, and a cutter 12 is symmetrically installed at the bottom of the support block 11. A hollow cavity is provided on the left and right sides of the support frame 9, and a sliding block 15 and a slider 19 are slidably connected in the hollow cavity. A protective cover 20 is fixedly connected to the front surface of the sliding block 15, and the protective cover 20 is fixedly connected to the slider 19. The protective cover 20 is a semi-enclosed structure and is made of transparent, impact-resistant and anti-static high-quality plastic sheet. It is convenient for operators to observe the progress of internal cleaning operations in real time, and can effectively prevent the blown debris from flying.

[0091] The inner wall of the protective cover 20 is symmetrically rotatably connected with an insertion rod 25, on which a brush roller 30 is installed, on which a brush head 31 is installed, and the brush head 31 is made of anti-static, soft and wear-resistant nylon material, and the bristles are spirally or staggeredly arranged, with a wide cleaning coverage area, and can sweep away tiny debris from the pins of the circuit board. A through groove 102 is opened on the workbench 1, and a collection box 43 is fixedly connected to the bottom surface of the workbench 1, and the collection box 43 is communicated with the through groove 102, and the side wall of the workbench 1 is fixedly connected to the finished product placement box 44.

[0092] It also includes a driving assembly, a clamping assembly, a picking assembly, a conveying assembly, a lifting assembly, a swing assembly, a swing assembly and a blowing assembly. The driving assembly is used to drive the clamping plate 5 to move horizontally. The driving assembly includes a fixed block 2, a first motor 201, a reciprocating screw 202, a screw nut 203 and a connecting rod 204. The fixed block 2 is fixedly connected to the bottom surface of the workbench 1. There are two fixed blocks 2. The first motor 201 is fixedly connected to the bottom surface of the workbench 1. The reciprocating screw 202 is fixedly connected to the output end of the first motor 201. The reciprocating screw 202 is rotatably connected to the fixed block 2. The screw nut 203 is threadedly connected to the reciprocating screw 202. The connecting rod 204 is fixedly connected to the top surface of the screw nut 203. The connecting rod 204 is rotatably connected to the first roller 4. The connecting rod 204 is slidably connected to the inner wall of the groove 101.

[0093] The clamping assembly is used to clamp the automobile circuit board, and the clamping assembly includes a slide groove 501, a double-headed screw 502, a nut 503 and a clamping plate 504. The slide groove 501 is symmetrically opened on the top surface of the clamping plate 5, the double-headed screw 502 is rotatably connected to the inner wall of the clamping plate 5, the double-headed screw 502 is fixedly connected to the rotating shaft 401, and the nut 503 is fixedly connected to the threaded section of the double-headed screw 502. The threaded sections on the double-headed screw 502 are arranged in opposite directions, so that when it rotates, the two sections of the threaded area synchronously drive the corresponding nut 503 to move toward or away from each other, thereby efficiently adjusting the spacing between the clamping plates 504.

[0094] The clamping plate 504 is fixedly connected to the top surface of the nut 503. The surface of the clamping plate 504 is often treated with an anti-static, soft wear-resistant coating, which can not only avoid static electricity damage to the electronic components of the circuit board, but also prevent scratches and indentations, ensuring the physical integrity and electrical performance stability of the circuit board during the clamping process.

[0095] In this embodiment, the first motor 201 is first started to drive the reciprocating screw 202 to rotate, and the screw nut 203 sleeved on the outside thereof slides along the guide of the reciprocating screw 202, and the connecting rod 204 on the top thereof drives the first roller 4 to slide in the long board 3, and drives the clamping plate 5 to move forward through the rotating shaft 401. At this time, driven by the clamping plate 5, the second roller 6 slides in the long board 3, and the double-headed screw 502 is driven to rotate during the sliding process of the first roller 4, and the nut 503 sleeved on the outside thereof slides inward immediately. As the first roller 4 and the second roller 6 continue to slide forward, when they slide to the bottom of the cutter 12, the two clamping plates 504 clamp the circuit board in the middle to prevent the circuit board from sliding during the repair process, which affects the repair effect. At this time, The cutter 12 is driven downward by the hydraulic push rod 10 to repair the redundant pins on the circuit board. When the repair is completed, the reciprocating screw 202 drives the screw nut 203 to return, and drives the first roller 4 and the second roller 6 to slide in the opposite direction, and at the same time drives the double-headed screw 502 to rotate in the opposite direction, so that the two nuts 503 drive the clamping plate 504 to gradually move away from the circuit board. When the clamping plate 5 returns to the initial position, the clamping plate 504 also completely releases the circuit board. At this time, the repaired circuit board can be taken away by the taking component, and then the circuit board to be repaired can be transported to the clamping plate 5 for repair again by the conveying component. There is no need for the staff to manually remove the repaired circuit board and then fix the circuit board to be repaired to the clamping plate 5, thereby effectively improving the work efficiency.

[0096] Embodiment 2:

At this time, the displacement sensor 609 sends a signal to start the hydraulic rod 605 to drive the mounting plate 606 to move down to just above the circuit board. Then, by controlling the electric telescopic rod 607, the two clamps 608 are driven to clamp the repaired circuit board in the middle. After the clamping is completed, the displacement sensor 609 sends a signal again to control the hydraulic rod 605 to lift the repaired circuit board.

[0100] At this time, the second motor 701 is started to drive the conveyor roller 801 to rotate, and its external transmission belt immediately transports the unrepaired circuit board to the clamping plate 5. When the clamping plate 5 moves again, the second roller 6 drives the spur rack 602 to engage with the spur gear 603. The spur gear 603 rotates under the force and drives the support rod 604 to rotate to the top of the finished product placement box 44. At this time, the displacement sensor 609 sends a signal again to control the hydraulic rod 605 and the electric telescopic rod 607 to place the repaired circuit board in the finished product placement box 44.
