Abstract

This invention discloses a pin repair device for automotive circuit board soldering, comprising a workbench with a groove on its top surface and a long plate symmetrically fixedly connected to the top surface of the workbench. The long plate is hollow and has sliding grooves on opposite sides. A first roller and a second roller are slidably connected inside the long plate, and a rotating shaft is rotatably connected to opposite sides of the first roller and the second roller. The device also includes a drive assembly, a clamping assembly, a picking assembly, a conveying assembly, a lifting assembly, a swinging assembly, and an air blowing assembly. In this invention, a first motor drives a reciprocating screw, which in turn moves the screw nut and connecting rod, causing the first roller to move the clamping plate. A double-ended screw then clamps the circuit board. After repair, the clamping plate resets and reverses the double-ended screw, moving the clamp away from the circuit board. This eliminates the need for manual handling when repairing multiple circuit boards.

Description

Technical Field

[0001] This invention relates to the field of automotive circuit board technology, and in particular to a pin repair device for automotive circuit board soldering. Background Technology

[0002] In the early stages of automobile development, electronic devices in cars were very limited. They mainly consisted of simple electrical systems, such as generators and spark plugs—basic ignition devices. Modern circuit boards did not yet exist; circuit connections were mostly made by directly connecting electrical components with wires.

[0003] For current repair equipment, the existing automotive circuit board soldering pin repair equipment disclosed in patent number "CN111315202B" involves inserting the circuit board to be processed into the V-shaped receiving grooves of two clamps. The V-shaped receiving grooves can 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. The turntable drives one end of each connecting rod to rotate 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 towards each other until the circuit board to be processed is clamped. This equipment uses the first motor to drive the two clamps to hold the circuit board, and then uses a hydraulic cylinder to drive the cutter to move down to cut off the excess pins on the circuit board. However, when this equipment is used to repair multiple circuit board pins, the operator needs to frequently alternate between the two clamps to install the automotive circuit board. After the repair work is completed, it is necessary to disassemble and replace the next automotive circuit board one by one to continue working. Such repetitive installation and disassembly operations not only severely slow down the repair process and reduce overall work efficiency, but also greatly increase the operational burden and labor intensity of the staff. Therefore, this application proposes an invention: a pin repair device for automotive circuit board soldering. Summary of the Invention

[0072] The present invention has the following beneficial effects:

[0073] 1. Through the drive assembly and clamping assembly, the first motor drives the reciprocating screw to rotate, causing the screw nut and connecting rod to slide along the groove, making the first roller move within the long plate. This causes the clamping plate to move synchronously. During the movement, the first roller drives the double-ended screw to rotate, and the nut and clamping plate hold the circuit board to prevent slippage. After repair, the reciprocating screw and clamping plate reset, the first roller causes the double-ended screw to reverse, and the clamping plate separates, releasing the circuit board. When repairing multiple circuit boards, there is no need to manually remove the repaired circuit boards and fix the circuit boards to be repaired, effectively reducing labor intensity.

[0074] 2. During the resetting process of the clamping plate, the second roller drives the rack to move via the fixed rod and meshes with the spur gear. The spur gear rotates under force, driving the support rod to rotate above the clamping plate. The displacement sensor controls the hydraulic rod and electric telescopic rod to clamp the circuit board. When the clamping plate moves again, the rack meshes with the spur gear again, causing the support rod to rotate above the finished product collection box. The displacement sensor sends a signal again and controls the hydraulic rod and electric telescopic rod to put 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 at the top of it rotate accordingly, so that the piston rod moves back and forth in the connecting pipe and transports air to the nozzle through the air supply pipe, blowing the circuit board debris into the through groove to prevent debris from being trapped.

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

Detailed Implementation

[0087] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0088] Example 1:

[0089] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A pin repair device for automotive circuit board soldering includes a workbench 1. The top surface of the workbench 1 has a groove 101, and the diameter of the groove 101 is larger than the diameter of the connecting rod 204, so that when the connecting rod 204 follows the operation of the drive component, it can only move smoothly along the direction of the groove 101.

[0090] A long plate 3 is symmetrically fixedly connected to the top surface of the workbench 1. The long plate 3 is hollow, and sliding grooves 301 are opened on opposite sides of the long plate 3. A first roller 4 and a second roller 6 are slidably connected inside the long plate 3. A rotating shaft 401 is rotatably connected to opposite sides of the first roller 4 and the second roller 6. A clamping plate 5 is rotatably connected to the rotating shaft 401. A connecting frame 8 is fixedly connected to the front end of the workbench 1. A support frame 9 is fixedly connected to the top surface of the workbench 1. A hydraulic push rod 10 is fixedly connected to the bottom surface of the support frame 9. A support block 11 is fixedly connected to the output end of the rod 10. A cutter 12 is symmetrically installed at the bottom of the support block 11. Hollow cavities are provided on the left and right sides of the support frame 9. A sliding block 15 and a slider 19 are slidably connected inside the hollow cavity. A protective cover 20 is fixedly connected to the front surface of the sliding block 15. The protective cover 20 is fixedly connected to the slider 19. The protective cover 20 has a semi-enclosed structure and is made of high-quality plastic sheet that is transparent, impact-resistant and anti-static. It is convenient for operators to observe the progress of the internal cleaning operation in real time and can effectively prevent the blown debris from scattering.

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

[0092] It also includes a drive assembly, a clamping assembly, a picking assembly, a conveying assembly, a lifting assembly, a swinging assembly, a swaying assembly, and an air blowing assembly. The drive assembly is used to drive the clamping plate 5 to move horizontally. The drive 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 worktable 1. There are two fixed blocks 2. The first motor 201 is fixedly connected to the bottom surface of the worktable 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 automotive circuit boards. The clamping assembly includes a slide groove 501, a double-ended 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-ended screw 502 is rotatably connected to the inner wall of the clamping plate 5. The double-ended screw 502 is fixedly connected to the rotating shaft 401. The nut 503 is fixedly connected to the threaded section of the double-ended screw 502. The threaded sections on the double-ended screw 502 are arranged in opposite directions, so that when it rotates, the two threaded areas synchronously drive the corresponding nuts 503 to move in opposite directions, thereby efficiently controlling the spacing of the clamping plate 504.

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

[0095] In this embodiment, the first motor 201 is first started to drive the reciprocating screw 202 to rotate. The screw nut 203, which is sleeved on the outside of the first motor 201, then slides along the guide of the reciprocating screw 202. The connecting rod 204 at the top of the first motor 201 then drives the first roller 4 to slide within the long plate 3. At the same time, the clamping plate 5 is moved forward by the rotating shaft 401. At this time, the second roller 6 slides within the long plate 3 under the drive of the clamping plate 5. During the sliding of the first roller 4, the double-ended screw 502 is rotated, and the nut 503 sleeved on the outside of the first roller 4 slides inward. As the first roller 4 and the second roller 6 continue to slide forward, when they reach the bottom of the cutter 12, the two clamping plates 504 clamp the circuit board in the middle to prevent the circuit board from slipping during the repair process, which would affect the repair effect. The hydraulic push rod 10 drives the cutter 12 to move downwards, repairing the excess pins on the circuit board. After 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 opposite directions. At the same time, it drives the double-headed screw 502 to rotate in opposite directions, 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 removed by the pick-up component, and 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 fix the circuit board to be repaired onto the clamping plate 5, thereby effectively improving work efficiency.

[0096] Example 2:

[0097] Unlike Example 1, referring to Figure 1 , Figure 2 , Figure 5 and Figure 9This embodiment further includes the following: a pick-up assembly for picking up a repaired automotive circuit board, comprising a fixed rod 601, a rack 602, a spur gear 603, a support rod 604, a hydraulic rod 605, a mounting plate 606, an electric telescopic rod 607, a clamping block 608, and a displacement sensor 609. The fixed rod 601 is fixedly connected to the side wall of the second roller 6, and the rack 602 is fixedly connected to the end of the fixed rod 601 away from the second roller 6. The spur gear 603 is connected via a short... The shaft is rotatably connected to the worktable 1, and the spur rack 602 meshes with the spur gear 603; the support rod 604 is fixedly connected to the top surface of the spur gear 603; the hydraulic rod 605 is fixedly connected to the inner side wall of the support rod 604; the mounting plate 606 is fixedly connected to the output end of the hydraulic rod 605, and the electric telescopic rod 607 is symmetrically arranged on the bottom surface of the mounting plate 606; the clamping block 608 is fixedly connected to the output end of the electric telescopic rod 607; and the displacement sensor 609 is installed on the side wall of the mounting plate 606.

[0098] The conveying assembly is used to convey automotive circuit boards to the clamping plate 5. The conveying assembly includes a support plate 7, a second motor 701, a conveying roller 801, and a conveyor belt 802. The support plate 7 is fixedly connected to the side wall of the connecting frame 8, the second motor 701 is fixedly connected to the top surface of the support plate 7, the conveying roller 801 is rotatably connected to the inner side wall of the connecting frame 8, there are two conveying rollers 801, the conveying rollers 801 are fixedly connected to the output end of the second motor 701, and the conveyor belt 802 is wound around the two conveying rollers 801.

[0099] In this embodiment, during the resetting process of the clamping plate 5, the second roller 6 drives the spur rack 602 on one side to move via the fixing rod 601 and meshes with the spur gear 603. The spur gear 603 rotates under force and drives the top support rod 604 to rotate above the clamping plate 5. At this time, the displacement sensor 609 sends a signal to start the hydraulic rod 605 to move the mounting plate 606 down to directly above the circuit board. Then, by controlling the electric telescopic rod 607, the two clamping blocks 608 clamp the repaired circuit board in the middle. After 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. The external transmission belt then transports the unrepaired circuit board to the clamping plate 5. When the clamping plate 5 moves again, the second roller 6 drives the rack 602 to mesh with the spur gear 603. The spur gear 603 rotates under force and drives the support rod 604 to rotate above 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. This process is repeated to greatly reduce the workload and complete the storage of the circuit board.

[0101] Example 3:

[0102] Reference Figure 6 , Figure 7 ,and Figure 8 Compared to Embodiment 1 and Embodiment 2, in this embodiment, the lifting assembly is used to lift the sliding block 15 and the sliding block 15. The lifting assembly includes a third motor 13, a threaded rod 14 and a guide rod 18. The third motor 13 is fixedly connected to the top surface of the support frame 9, and the threaded rod 14 is fixedly connected to the output end of the third motor 13. The threaded rod 14 is rotatably connected to the inner wall of the hollow cavity. The hollow cavity ensures the smooth rotation of the threaded rod 14 and provides stable guidance for the sliding of the sliding block 15, ensuring that its lifting trajectory is accurate and without deviation.

[0103] The threaded rod 14 is threadedly connected to the sliding block 15, and the guide rod 18 is fixedly connected to the inner wall of the hollow cavity. The guide rod 18 is slidably connected to the slider 19.

[0104] The oscillating assembly drives the brush head 31 to oscillate left and right. The oscillating assembly includes a concave plate 21, a support plate 22, a cylinder 23, a rack 24, a drive gear 26, a rotating shaft 27, a meshing wheel 28, and a driven gear 29. The concave plate 21 is fixedly connected to the side wall of the protective cover 20, the support plate 22 is fixedly connected to the side wall of the concave plate 21, the cylinder 23 is fixedly connected to the top surface of the support plate 22, the rack 24 is fixedly connected to the output end of the cylinder 23, and the rack 24 is slidably connected to the inner wall of the concave plate 21. The drive gear 26 is fixedly connected to the insert rod 25, and the drive gear 26 meshes with the rack 24. The rotating shaft 27 is rotatably connected to the side wall of the protective cover 20, the meshing wheel 28 is fixedly connected to the rotating shaft 27, and the drive gear 29... The driven gear 29 is fixedly connected to the insert rod 25 and meshes with the meshing wheel 28. The diameter of the driving gear 26 can mesh with both the rack 24 and the meshing wheel 28 simultaneously. In this way, when the rack 24 drives the driving gear 26 to rotate, the driving gear 26 can mesh with the meshing wheel 28, thereby driving the meshing wheel 28 to rotate. The rotation direction of the meshing wheel 28 is opposite to the rotation direction of the driving gear 26. When the meshing wheel 28 drives the driven gear 29 to rotate, the rotation direction of the driven gear 29 is opposite to the rotation direction of the meshing wheel 28, causing the brush roller 30 and brush head 31 to swing left and right in the protective cover 20 so as to clean the debris at the circuit board pins into the collection box 43.

[0105] The air blowing assembly is used to remove debris generated during circuit board repair. The air blowing assembly includes a square groove 901, a protrusion 16, a toothed plate 17, a support block 32, a drive shaft 33, a planetary gear 34, a round rod 35, a connecting rod 36, a piston rod 37, a support block 39, a connecting pipe 38, an air outlet 40, an air supply pipe 41, and a nozzle 42. The square groove 901 is formed on the side wall of the support frame 9. The protrusion 16 is fixedly connected to the side wall of the sliding block 15 and slidably connected to the inner wall of the square groove 901. The toothed plate 17 is fixedly connected to the top surface of the protrusion 16. The protective cover 20 has long rods on both sides. Therefore, after the protective cover 20 is lowered to a certain position, the toothed plate 17 will contact the planetary gear 34, thereby driving the air blowing assembly to blow air. The debris blown out will be blocked by the protective cover 20 to prevent premature blowing and disorderly scattering of debris.

[0106] Support block 32 is fixedly connected to the side wall of connecting frame 8. Drive shaft 33 is rotatably connected to the side wall of support block 32. Planetary gear 34 is fixedly connected to drive shaft 33 and meshes with gear plate 17. Round rod 35 is fixedly connected to the front surface of planetary gear 34. Connecting rod 36 is hinged to round rod 35. Piston rod 37 is hinged to the end of connecting rod 36 away from round rod 35. Support block 39 is fixedly connected to support frame 9. Connecting pipe 38 is located on top of support block 39. The top of support block 39 is consistent with the shape of connecting pipe 38. Piston rod 37 is sealed inside connecting pipe 38. Round rod 35 is located at the eccentric position of planetary gear 34, so that... When the planetary gear 34 rotates, it drives the round rod 35 and the connecting rod 36 to rotate along the planetary gear 34, which in turn drives the piston rod 37 to reciprocate in the sealed pipe, thereby transporting air to the air supply pipe 41. The air outlet 40 is opened on the connecting pipe 38. The air outlet 40 is equipped with a filter screen inside, which can block dust in the air and prevent dust from entering the sealed pipe from the air outlet 40. The air supply pipe 41 is set on the connecting pipe 38. The nozzle 42 is set at the end of the air supply pipe 41 away from the connecting pipe 38. The nozzle 42 is provided with a mounting block on one side, which makes it easy to install the nozzle 42 on the protective cover 20. At the same time, the nozzle 42 is set in a downward tilt.

[0107] In this embodiment, the threaded rod 14 is driven to rotate by starting the third motor 13. The sliding block 15 sleeved on its outside then slides along the hollow cavity of the support frame 9. At the same time, the protective cover 20 on the side wall moves down and drives the slider 19 on one side to slide along the sliding rod. During the downward movement of the sliding block 15, the protrusion 16 and toothed plate 17 on the side wall move down. During the downward movement of the toothed plate 17, it meshes with the planetary gear 34. The planetary gear 34 rotates under force and drives the round rod 35 and connecting rod 36 to rotate around the planetary gear 34. The piston rod 37 at the top slides back and forth in the connecting pipe 38 and transports air to the nozzle 42 through the air supply pipe 41, blowing the debris on the circuit board into the through groove 102 and falling into the collection box 43.

[0108] After the blowing is finished, the starting cylinder 23 drives the rack 24 to slide in the concave groove and mesh with the drive gear 26. The drive gear 26 rotates under force, which drives the meshing wheel 28 to rotate. The meshing wheel 28 meshes with the driven gear 29 on one side. The driven gear 29 then rotates, causing the two insert rods 25 to rotate simultaneously. The brush roller 30 and brush head 31 at the bottom then clean along the pins on the circuit board to prevent debris from remaining on the circuit board.

[0109] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
