Description

Technical Field

[0001] This invention relates to the field of circuit board processing technology, and in particular to a circuit board processing equipment and processing method. Background Technology

[0002] As electronic products become smaller and more functional, circuit board designs are becoming increasingly complex. Traditional processing methods are struggling to meet the requirements for high precision and detail. The market demand for rapid iteration and prototype verification is increasing. Laser etching can quickly produce circuit boards and accelerate product time-to-market.

[0003] The existing circuit board processing involves time-consuming manual handling and placement. In highly mixed production environments, manual operation is difficult to adapt quickly to the needs of different products, reducing the flexibility of the production line. At the same time, the inability to adjust the position of circuit boards with different designs limits their adaptability, making it impossible to meet diverse product requirements. Furthermore, residual smoke may affect the transmission and focusing of the laser, resulting in unsatisfactory etching results. Particulate matter in the smoke may deposit on the circuit board, causing contamination or damage to the components. Summary of the Invention

[0004] To address the technical problems of existing circuit board processing, such as the time-consuming manual handling and placement of circuit boards, the inability to adjust the position for different designs limiting their adaptability, and the potential for particulate matter in fumes to deposit on the circuit boards, causing contamination or damage to components, this invention proposes a circuit board processing equipment and method.

[0005] The present invention proposes a circuit board processing equipment, including a frame with a laser instrument housing, and further including a gripping device, an adjustment device, and a cleaning device installed within the frame.

[0006] A gripping device is located inside the frame and grips the circuit board to be laser etched. The gripping device includes a moving mechanism and a fixing mechanism. The moving mechanism includes a lifting rod, and the movement of the lifting rod drives the fixing mechanism to move. The fixing mechanism includes a fixing block, and the extension and retraction of the fixing block fixes the circuit board.

[0007] An adjustment device is located inside the frame and adjusts the position of the circuit board to be laser etched. The adjustment device includes an adjustment mechanism and an opening and closing mechanism. The adjustment mechanism includes a vacuum suction cup, and the movement of the vacuum suction cup causes the adsorbed circuit board to move. The opening and closing mechanism includes an opening and closing screw and an opening and closing plate, and the rotation of the opening and closing screw causes the opening and closing plate to move.

[0008] A cleaning device is located inside the frame and cleans the surface of the circuit board after laser etching. The cleaning device includes a conveying mechanism and a cleaning mechanism. The conveying mechanism includes a suction fan that sucks up the fumes generated during the etching process. The cleaning mechanism includes a cleaning brush that rotates to clean the surface of the circuit board.

[0009] Preferably, the moving mechanism further includes a moving motor, which is fixedly installed on the inner wall of the frame. The output shaft of the moving motor is slidably sleeved with a drive gear, and the output shaft of the moving motor is fixedly installed with a drive electromagnet. The outer surface of the drive electromagnet and the outer surface of the drive gear are magnetically connected through an adsorption element. The output shaft of the moving motor is fixedly installed with a drive spring that forces the drive gear to reset. The inner wall of the frame is rotatably connected to a moving screw and a fixed rod through bearings. The outer surface of the moving screw is fixedly installed with a moving gear. After the drive gear is reset, it meshes with the moving gear. The outer surface of the moving screw is threadedly connected to a sleeve, and the outer surface of the sleeve is rotatably connected to a moving rod with a gear.

[0010] Through the above technical solution, the moving motor drives the drive gear to rotate, which in turn energizes the electromagnet. After the drive gear moves, it meshes with the rotating gear, driving the fixed rod to rotate. The electromagnet is de-energized, and the driving spring resets the drive gear to mesh with the moving gear, driving the moving screw to rotate. The moving screw is threadedly connected to the sleeve, driving it to rotate and move. Since the sleeve and the moving rod are rotatably connected, the rotation of the moving rod does not affect the sleeve's movement, so that the lifting screw can be driven to rotate through the bevel gear set.

[0011] Preferably, one end of the movable rod is rotatably connected to a movable frame, and a rotating gear and a rotary gear are fixedly installed on the outer surface of the fixed rod, respectively. After the drive gear moves, it meshes with the rotating gear, and the rotary gear meshes with the gear of the movable rod. A lifting screw is rotatably connected to the inner wall of the movable frame, and one end of the movable rod drives the lifting screw to rotate through a bevel gear set. The outer surface of the lifting screw is threadedly connected to the inner wall of the groove of the lifting rod.

[0012] Through the above technical solution, the moving rod is rotatably connected to the moving frame, and while the moving frame is moved, its rotation does not affect the moving frame. The driving electromagnet is energized, and the driving gear moves and meshes with the rotating gear, driving the fixed rod to rotate. Since the rotating gear meshes with the gear of the moving rod, it is driven to rotate, thereby driving the lifting screw rotatably connected to the moving frame to rotate through the bevel gear set, so as to rotate and move the lifting rod threadedly connected to it, so as to drive the fixed frame rotatably connected to it to rise and fall.

[0013] Preferably, the fixing mechanism further includes a fixing frame, which is rotatably connected to one end of the lifting rod. A hydraulic cylinder is fixedly installed on the inner wall of the fixing frame, and a telescopic frame is fixedly installed on one end of the telescopic rod of the hydraulic cylinder. The outer surface of the telescopic frame is slidably sleeved with the inner wall of the groove of the fixing frame. A sensor is fixedly installed on the inner wall of the telescopic frame. The inner wall of the fixing frame is slidably sleeved with the outer surface of the fixing block. A fixing spring forcing the fixing block to reset is fixedly installed on the outer surface of the fixing frame. A roller is rotatably connected to the outer surface of the fixing block, and the outer surface of the roller is slidably inserted into the outer surface of the telescopic frame.

[0014] Through the above technical solution, the fixed frame is rotatably connected to the lifting rod, and the fixed frame is lifted and lowered at the same time. The rotation of the fixed frame does not affect the fixed frame. The extension and retraction of the hydraulic cylinder's telescopic rod drives the telescopic frame to lift and lower. The telescopic frame descends on the fixed frame with the sliding sleeve. Due to its sliding insertion with the roller, its arc design causes the roller to drive the rotating fixed block to expand. The telescopic frame rises, and the fixed spring resets the fixed block, so as to fix circuit boards of different sizes.

[0015] Preferably, the adjustment mechanism further includes an adjustment motor, which is fixedly mounted on the outer surface of the frame. An adjustment gear is slidably sleeved on the output shaft of the adjustment motor. An adjustment electromagnet is fixedly mounted on the output shaft of the adjustment motor. The outer surface of the adjustment electromagnet and the outer surface of the adjustment gear are magnetically connected through an adsorption element. An adjustment spring that forces the adjustment gear to reset is fixedly mounted on the outer surface of the adjustment motor. An adjustment screw and an adjustment rod are rotatably connected to the inner wall of the frame through bearings. A transfer gear is fixedly mounted on the outer surface of the adjustment screw. After the adjustment gear resets, it meshes with the transfer gear. An adjusting gear is fixedly mounted on the outer surface of the adjustment rod. After the adjustment gear moves, it meshes with the adjusting gear.

[0016] The above technical solution adjusts the motor to drive the adjusting gear to rotate, energizes the adjusting electromagnet, and after the adjusting gear moves, it meshes with the adjusting gear, driving the adjusting rod to rotate. When the adjusting electromagnet is de-energized, the adjusting spring resets the adjusting gear and meshes with the transfer gear, driving the adjusting screw to rotate, thus meeting different needs and enhancing the versatility of the adjusting motor.

[0017] Preferably, a slide rod is fixedly installed on the outer surface of the frame, an adjustment frame is threadedly connected to the outer surface of the adjustment screw, the adjustment frame is slidably sleeved on the outer surface of the slide rod, the inner wall of the groove of the adjustment frame is rotatably sleeved with the outer surface of the adjustment rod, an adjustment screw is rotatably connected to the inner wall of the adjustment frame, a worm gear is fixedly installed at one end of the adjustment screw, the outer surface of the adjustment screw is threadedly connected to the inner wall of the groove of the vacuum suction cup, the vacuum suction cup is slidably inserted into the inner wall of the adjustment frame, and a worm gear is slidably sleeved on the outer surface of the adjustment rod, the worm gear meshing with the worm gear.

[0018] By adjusting the rotation of the screw, the adjusting frame threaded to it moves on the sliding sleeve and the rotating sleeve of the adjusting rod, which in turn drives the worm gear slidably sleeved with the adjusting rod to move. Through the meshing of the worm gear and the worm wheel, the adjusting screw fixed to it rotates within the rotatingly connected adjusting frame, thereby driving the vacuum chuck threaded to the adjusting screw to move on the slidingly inserted adjusting frame, so as to adjust the X and Y axis positions of the circuit board.

[0019] Preferably, the opening and closing mechanism further includes a synchronous wheel, one of which is fixedly mounted on the outer surface of the opening and closing screw. The opening and closing screw is rotatably connected to the inner wall of the frame. An opening and closing electromagnet is fixedly mounted on the output shaft of the adjusting motor. The outer surface of the opening and closing electromagnet is rotatably connected to the inner wall of the groove of the other synchronous wheel. The inner wall of the groove of the opening and closing electromagnet is magnetically connected to the outer surface of the other synchronous wheel through an adsorption element. The other synchronous wheel drives the first synchronous wheel to rotate through a synchronous belt. The opening and closing plate is threadedly connected to the outer surface of the opening and closing screw, and the outer surface of the opening and closing plate is slidably inserted into the inner wall of the groove of the frame.

[0020] Through the above technical solution, by adjusting the motor to drive the opening and closing electromagnet to rotate, since the opening and closing electromagnet is rotatably connected to a synchronous wheel, its rotation does not affect the synchronous wheel. When the opening and closing electromagnet is energized, the synchronous wheel that is magnetically connected to it through an adsorption component rotates. This drives the synchronous wheel that is fixedly installed with the opening and closing screw to rotate through the synchronous belt. The opening and closing screw rotates synchronously, causing the opening and closing plate that is threaded to it to move within the sliding insertion frame in order to seal the frame.

[0021] Preferably, the conveying mechanism further includes a conveying fan, which is fixedly installed on the outer surface of the frame. The air outlet of the conveying fan is fixedly connected to the outer surface of the frame through an air outlet pipe. The suction fan is fixedly installed on the outer surface of the frame, and the air outlet of the suction fan is fixedly connected to the outer surface of the frame through an air outlet pipe. The air inlets of the conveying fan and the suction fan are respectively fixedly connected to air inlet pipes with filter layers.

[0022] Through the above technical solution, the exhaust fan draws in the smoke inside the frame through the exhaust pipe fixedly connected to the frame, and discharges it into the air through the intake pipe fixedly connected to it. The filter layer in the intake pipe filters the smoke. At the same time, the conveying fan fixedly installed on the frame is started, and the intake pipe with the filter layer draws in the air and delivers it to the frame through the exhaust pipe fixedly connected to its exhaust port, so as to remove the smoke generated inside the frame due to laser etching.

[0023] Preferably, the cleaning mechanism further includes a cleaning plate, the outer surface of which is fixedly installed to the outer surface of the frame by bolts, a circular frame with gears is fixedly installed on the outer surface of the cleaning plate, a cleaning motor is fixedly installed on the inner wall of the cleaning plate, a cleaning frame is fixedly installed on the output shaft of the cleaning motor, the outer surface of the cleaning frame is rotatably connected to the outer surface of the cleaning brush, a cleaning gear is fixedly installed on the outer surface of the cleaning brush, and the cleaning gear meshes with the gear of the circular frame.

[0024] The above technical solution involves fixing the cleaning plate and frame together with bolts, allowing for disassembly and cleaning of the cleaning brush, as well as replacement of the cleaning solution. The cleaning motor drives the cleaning frame to rotate, causing the cleaning brush connected to it to revolve. The cleaning gear fixed on the cleaning brush meshes with the gear on the circular frame, driving its rotation. Simultaneously, the position of the circuit board adsorbed on the vacuum suction cup can be adjusted by the adjustment mechanism for thorough cleaning.

[0025] The present invention provides a processing method for circuit board processing equipment, comprising the following steps:

[0026] S1: When it is necessary to move the fixing mechanism to the top of the circuit board, start the moving motor to drive the drive gear to rotate, drive the electromagnet to de-energize, drive the spring to reset the drive gear and mesh with the moving gear, drive the moving screw to rotate, drive the sleeve threaded to rotate and move, cause the moving rod rotatably connected to it to move, thereby driving the moving frame rotatably connected to the moving rod to move to the top of the circuit board.

[0027] S2: When it is necessary to grip the circuit board, the hydraulic cylinder is activated. The telescopic rod of the hydraulic cylinder drives the telescopic frame, which is fixedly installed with it, to move down in the groove of the fixed frame that is slidably inserted. Since the telescopic frame is slidably inserted with the roller, the telescopic frame moves down, causing the roller to drive the fixed block that is rotatably connected with it to expand. The sensor fixedly installed with the telescopic frame senses the circuit board below and adjusts the distance between the fixed mechanism and the circuit board. At the same time, the electromagnet is driven to be energized, and the drive gear moves and meshes with the rotating gear, driving the fixed rod to rotate. At the same time, the rotating gear fixedly installed with the fixed rod rotates. The rotating gear meshes with the gear of the moving rod, driving the moving rod that is rotatably connected with the sleeve to rotate. The moving rod drives the lifting screw that is rotatably connected with the moving frame to rotate through the bevel gear set, causing the lifting rod that is threaded to rotate and move. This causes the fixed frame that is rotatably connected with the lifting rod to descend to the designated position. When the telescopic rod of the hydraulic cylinder drives the telescopic frame to rise, the fixed spring fixedly installed with the fixed frame resets the fixed block that is slidably sleeved with it, and the circuit board is gripped.

[0028] S3: When the frame needs to be sealed, the circuit board is placed on the vacuum suction cup by the gripping device, and the vacuum suction cup is activated to adsorb and fix it. At the same time, the adjustment motor is started to drive the adjustment gear and the opening and closing electromagnet to rotate. The opening and closing electromagnet is energized, which causes the synchronous wheel that is magnetically connected to it through the adsorption component and rotates to rotate. The synchronous wheel that is fixedly installed with the opening and closing screw is driven to rotate through the synchronous belt. The rotation of the opening and closing screw causes the opening and closing plate that is rotated to move within the slidingly inserted frame to seal the frame.

[0029] S4: When etching the circuit board through the laser instrument housing, and when adjusting the Y-axis position of the circuit board, the opening and closing electromagnet is de-energized, the adjusting electromagnet is de-energized, the adjusting spring resets the adjusting gear and engages with the transfer gear, driving the adjusting screw fixedly mounted with the transfer gear to rotate, causing the adjusting frame threaded to move on the sliding sleeve and rotating sleeve of the adjusting rod, synchronously driving the adjusting screw rotatably connected to it and the worm gear slidably sleeved with the adjusting rod to move. When adjusting the X-axis position of the circuit board, the adjusting electromagnet is energized at the same time, the adjusting gear moves and engages with the adjusting gear, driving the adjusting rod to rotate, the worm gear engages with the worm wheel fixedly mounted on the adjusting screw, driving the adjusting screw to rotate, causing the vacuum chuck threaded to move on the sliding sleeve of the adjusting frame;

[0030] S5: When it is necessary to remove the smoke generated during the laser etching process inside the frame, start the suction fan fixedly installed above the frame, and suck the smoke inside through the air outlet pipe fixedly connected to the frame, and discharge it into the air through the air inlet pipe fixedly connected to the suction fan. The filter layer in the air inlet pipe filters it. At the same time, start the conveying fan fixedly installed below the frame, and the air inlet pipe with the filter layer sucks in the air and delivers it to the frame through the air outlet fixedly connected to it through the air outlet pipe.

[0031] S6: When it is necessary to clean the surface of the laser-etched circuit board, start the cleaning motor fixedly installed inside the cleaning plate, so that the cleaning frame fixedly installed with its output shaft rotates, driving the cleaning brush connected to the cleaning frame to revolve. Since the cleaning gear fixedly installed on the cleaning brush meshes with the gear of the circular frame, it rotates on its own axis, thus cleaning the circuit board.

[0032] The beneficial effects of this invention are as follows:

[0033] 1. By setting up a conveying device, the moving motor drives the drive gear to rotate, the drive electromagnet is de-energized, the drive spring resets the drive gear and meshes with the moving gear, drives the moving screw to rotate, drives the sleeve to rotate and move, drives the moving frame to move through the moving rod, drives the drive electromagnet to be energized, the drive gear moves and meshes with the rotating gear, drives the fixed rod to rotate. Since the rotating gear meshes with the gear of the moving rod, it drives it to rotate, thereby driving the lifting screw rotatably connected to the moving frame to rotate through the bevel gear set, causing the lifting rod threaded to rotate and move, so as to drive the fixed frame rotatably connected to it to rise and fall. The extension rod of the hydraulic cylinder extends and retracts, driving the telescopic frame to rise and fall. The telescopic frame descends on the fixed frame with the sliding sleeve. Since it slides into the roller, its arc design causes the roller to drive the fixed block rotatably connected to expand, the telescopic frame rises, and the fixed spring resets the fixed block, so as to fix circuit boards of different sizes. This solves the technical problem that when processing circuit boards, manual gripping and placing of circuit boards is time-consuming, and in a highly mixed production environment, manual operation is difficult to quickly adapt to the needs of different products, reducing the flexibility of the production line.

[0034] 2. By setting up a purification device, the motor drives the adjusting gear to rotate, the electromagnet is de-energized, and the adjusting spring resets the adjusting gear to mesh with the transfer gear, driving the adjusting screw to rotate. The rotation of the adjusting screw causes the adjusting frame, which is threadedly connected to it, to move on the slidingly sleeved slide rod and the rotatingly sleeved adjusting rod. Simultaneously, this drives the worm gear, which is slidably sleeved with the adjusting rod, to move. When the adjusting electromagnet is energized, the adjusting gear, after moving, meshes with the adjusting gear, driving the adjusting rod to rotate. Through the meshing of the worm gear and worm wheel, the adjusting screw, which is fixedly installed with it, rotates within the rotatingly connected adjusting frame, thereby driving the adjusting screw... The threaded vacuum suction cup moves on the sliding insertion adjustment frame. The adjustment motor drives the opening and closing electromagnet to rotate. When the opening and closing electromagnet is energized, the synchronous wheel that is magnetically connected to it via the adsorption component rotates. This, in turn, drives the synchronous wheel that is fixedly installed with the opening and closing screw to rotate via the synchronous belt. The opening and closing screw rotates synchronously, causing the opening and closing plate that is threaded to it to move within the sliding insertion frame to seal the frame. This solves the technical problem that existing circuit boards cannot be adjusted in position during processing, which limits their adaptability and makes it impossible to meet diverse product requirements.

[0035] 3. By setting up a cleaning device, the suction fan draws in the internal smoke through the exhaust pipe fixedly connected to the frame, and discharges it into the air through the intake pipe fixedly connected to it. The filter layer in the intake pipe filters the smoke. At the same time, the conveying fan fixedly installed in the frame is started, and the intake pipe with the filter layer draws in the air and delivers it to the frame, which is fixedly connected to its exhaust port through the exhaust pipe. The cleaning plate is fixedly installed to the frame with bolts so that it can be disassembled for cleaning of the cleaning brush and replacement of the cleaning fluid. The cleaning motor drives the cleaning frame to rotate, causing the cleaning brush connected to it to revolve. Since the cleaning gear fixedly installed on the cleaning brush meshes with the gear on the circular frame, it drives the brush to rotate. At the same time, the position of the circuit board adsorbed on the vacuum suction cup can be adjusted by the adjustment mechanism to ensure thorough cleaning. This solves the technical problem that when processing circuit boards, residual smoke may affect the transmission and focusing of laser, resulting in unsatisfactory etching effect, and particulate matter in the smoke may be deposited on the circuit board, causing contamination or damage to the components.

[0051] 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.

[0052] Reference Figures 1-14 A circuit board processing device includes a frame 1 with a laser housing, and also includes a gripping device, an adjusting device, and a cleaning device installed within the frame 1.

[0053] like Figure 2-7As shown, a gripping device is provided for gripping the circuit board. The gripping device is located inside the frame 1 and grips the circuit board that needs to be laser etched. The gripping device includes a moving mechanism and a fixing mechanism. The moving mechanism includes a lifting rod 33. The movement of the lifting rod 33 drives the fixing mechanism to move. The fixing mechanism includes a fixing block 44. The extension and retraction of the fixing block 44 fixes the circuit board.

[0054] Specifically, to move the sleeve 27, the moving mechanism also includes a moving motor 2. The moving motor 2 is fixedly installed on the inner wall of the frame 1. The output shaft of the moving motor 2 is slidably sleeved with a drive gear 21. A drive electromagnet 22 is fixedly installed on the output shaft of the moving motor 2. The outer surface of the drive electromagnet 22 is magnetically connected to the outer surface of the drive gear 21 through an adsorption component. A drive spring 23 is fixedly installed on the output shaft of the moving motor 2 to force the drive gear 21 to reset. A moving screw 24 and a fixed rod 25 are rotatably connected to the inner wall of the frame 1 through bearings. A moving gear 26 is fixedly installed on the outer surface of the moving screw 24. After the drive gear 21 resets, it meshes with the moving gear 26. A sleeve 27 is threadedly connected to the outer surface of the sleeve 27. A moving rod 28 with gears is rotatably connected to the outer surface of the sleeve 27. The moving motor 2 drives the drive gear 21 to rotate, which energizes the drive electromagnet 22. After the drive gear 21 moves, it meshes with the rotating gear 31, which drives the fixed rod 25 to rotate. The drive electromagnet 22 is de-energized, and the drive spring 23 resets the drive gear 21 to mesh with the moving gear 26, which drives the moving screw 24 to rotate. The moving screw 24 is threadedly connected to the sleeve 27, which is driven to rotate and move. Since the sleeve 27 is rotatably connected to the moving rod 28, the rotation of the moving rod 28 does not affect the movement of the sleeve 27, so that the lifting screw 34 can be driven to rotate through the bevel gear set.

[0055] Specifically, in order to drive the fixed frame 4 to rise and fall, one end of the moving rod 28 is rotatably connected to the moving frame 3. The outer surface of the fixed rod 25 is fixedly mounted with a rotating gear 31 and a rotating gear 32. After the driving gear 21 moves, it meshes with the rotating gear 31. The rotating gear 32 meshes with the gear of the moving rod 28. The inner wall of the moving frame 3 is rotatably connected to the lifting screw 34. One end of the moving rod 28 drives the lifting screw 34 to rotate through a bevel gear set. The outer surface of the lifting screw 34 is threadedly connected to the inner wall of the groove of the lifting rod 33. The moving rod 28 is rotatably connected to the moving frame 3, and while driving the moving frame 3 to move, its rotation does not affect the moving frame 3. The driving electromagnet 22 is energized, and after the driving gear 21 moves, it meshes with the rotating gear 31, driving the fixed rod 25 to rotate. Since the rotating gear 32 meshes with the gear of the moving rod 28, it drives it to rotate. Thus, through the bevel gear set, the lifting screw 34 rotatably connected to the moving frame 3 is driven to rotate, causing the lifting rod 33 threadedly connected to it to rotate and move, so as to drive the fixed frame 4 rotatably connected to it to rise and fall.

[0056] Specifically, to fix circuit boards of different sizes, the fixing mechanism also includes a fixing frame 4, which is rotatably connected to one end of the lifting rod 33. A hydraulic cylinder 41 is fixedly installed on the inner wall of the fixing frame 4, and a telescopic frame 42 is fixedly installed on one end of the telescopic rod of the hydraulic cylinder 41. The outer surface of the telescopic frame 42 is slidably sleeved with the inner wall of the groove of the fixing frame 4. A sensor 43 is fixedly installed on the inner wall of the telescopic frame 42. The inner wall of the fixing frame 4 is slidably sleeved with the outer surface of the fixing block 44. A fixing spring 45 forcing the fixing block 44 to reset is fixedly installed on the outer surface of the fixing frame 4. A roller 46 is rotatably connected, and the outer surface of the roller 46 is slidably inserted into the outer surface of the telescopic frame 42. It is rotatably connected to the lifting rod 33 through the fixed frame 4. While driving the fixed frame 4 to rise and fall, its rotation does not affect the fixed frame 4. The telescopic rod of the hydraulic cylinder 41 extends and retracts, driving the telescopic frame 42 to rise and fall. The telescopic frame 42 descends on the fixed frame 4 which is slidably connected. Due to its slidable insertion with the roller 46, its arc design causes the roller 46 to drive the rotatably connected fixed block 44 to expand, and the telescopic frame 42 rises. The fixed spring 45 resets the fixed block 44 so as to fix circuit boards of different sizes.

[0057] like Figure 8-11 As shown, in order to adjust the position of the circuit board, an adjustment device is provided. The adjustment device is located inside the frame 1 and adjusts the position of the circuit board that needs to be laser etched. The adjustment device includes an adjustment mechanism and an opening and closing mechanism. The adjustment mechanism includes a vacuum suction cup 64. The movement of the vacuum suction cup 64 drives the suction circuit board to move. The opening and closing mechanism includes an opening and closing screw 71 and an opening and closing plate 73. The rotation of the opening and closing screw 71 drives the opening and closing plate 73 to move.

[0058] Specifically, to meet different needs and enhance the versatility of the adjusting motor 5, the adjusting mechanism also includes an adjusting motor 5. The adjusting motor 5 is fixedly mounted on the outer surface of the frame 1. An adjusting gear 51 is slidably sleeved on the output shaft of the adjusting motor 5. An adjusting electromagnet 52 is fixedly mounted on the output shaft of the adjusting motor 5. The outer surface of the adjusting electromagnet 52 is magnetically connected to the outer surface of the adjusting gear 51 through an adsorption component. An adjusting spring 53 is fixedly mounted on the outer surface of the adjusting motor 5 to force the adjusting gear 51 to reset. An adjusting screw 54 and an adjusting rod 55 are rotatably connected to the inner wall of the frame 1 through bearings. The adjusting screw 54... A transfer gear 56 is fixedly installed on the outer surface of the adjusting rod 55. After the adjusting gear 51 is reset, it meshes with the transfer gear 56. An adjusting gear 57 is fixedly installed on the outer surface of the adjusting rod 55. After the adjusting gear 51 moves, it meshes with the adjusting gear 57. The adjusting motor 5 drives the adjusting gear 51 to rotate. The adjusting electromagnet 52 is energized. After the adjusting gear 51 moves, it meshes with the adjusting gear 57, driving the adjusting rod 55 to rotate. The adjusting electromagnet 52 is de-energized. The adjusting spring 53 resets the adjusting gear 51 to mesh with the transfer gear 56, driving the adjusting screw 54 to rotate, so as to meet different needs and enhance the versatility of the adjusting motor 5.

[0059] Specifically, to adjust the X and Y axis positions of the circuit board, a slide rod 6 is fixedly mounted on the outer surface of the frame 1, and an adjustment frame 61 is threadedly connected to the outer surface of the adjustment screw 54. The adjustment frame 61 is slidably sleeved on the outer surface of the slide rod 6, and the inner wall of the groove of the adjustment frame 61 is rotatably sleeved with the outer surface of the adjustment rod 55. An adjustment screw 62 is rotatably connected to the inner wall of the adjustment frame 61, and a worm gear 63 is fixedly mounted on one end of the adjustment screw 62. The outer surface of the adjustment screw 62 is threadedly connected to the inner wall of the groove of the vacuum suction cup 64, and the vacuum suction cup 64 is slidably inserted into the inner wall of the adjustment frame 61. The adjustment rod 54... A worm gear 65 is slidably sleeved on the outer surface of the circuit board 5. The worm gear 65 meshes with the worm wheel 63. When the adjusting screw 54 rotates, the adjusting frame 61, which is threaded to it, moves on the sliding rod 6 and the rotating adjusting rod 55. This moves the worm gear 65, which is slidably sleeved with the adjusting rod 55, in sync. Through the meshing of the worm gear 65 and the worm wheel 63, the adjusting screw 62, which is fixedly installed with it, rotates within the rotating adjusting frame 61. This causes the vacuum chuck 64, which is threaded to the adjusting screw 62, to move on the sliding adjusting frame 61, so as to adjust the X and Y axis positions of the circuit board.

[0060] Specifically, to seal the frame 1, the opening and closing mechanism also includes a synchronous wheel 7. One synchronous wheel 7 is fixedly mounted on the outer surface of the opening and closing screw 71, which is rotatably connected to the inner wall of the frame 1. An opening and closing electromagnet 72 is fixedly mounted on the output shaft of the adjusting motor 5. The outer surface of the electromagnet 72 is rotatably connected to the inner wall of the groove of the other synchronous wheel 7. The inner wall of the groove of the electromagnet 72 is magnetically connected to the outer surface of the other synchronous wheel 7 via an adsorption element. The other synchronous wheel 7 drives the first synchronous wheel 7 to rotate via a synchronous belt. The opening and closing plate 73 is threadedly connected to the opening and closing screw. The outer surface of the opening and closing plate 73 is slidably inserted into the inner wall of the groove of the frame 1. The opening and closing electromagnet 72 is driven to rotate by the motor 5. Since the opening and closing electromagnet 72 is rotatably connected to a synchronous wheel 7, its rotation does not affect the synchronous wheel 7. When the opening and closing electromagnet 72 is energized, the synchronous wheel 7, which is magnetically connected to it through an adsorption component, rotates. This drives the synchronous wheel 7, which is fixedly installed with the opening and closing screw 71, to rotate through the synchronous belt. The opening and closing screw 71 rotates synchronously, causing the opening and closing plate 73, which is threaded to it, to move within the slidably inserted frame 1 in order to seal the frame 1.

[0061] like Figure 12-14 As shown, in order to clean the surface of the circuit board after laser etching, a cleaning device is provided. The cleaning device is located inside the frame 1 and cleans the surface of the circuit board after laser etching. The cleaning device includes a conveying mechanism and a cleaning mechanism. The conveying mechanism includes a suction fan 81, which sucks up the smoke generated during the etching process. The cleaning mechanism includes a cleaning brush 94, which cleans the surface of the circuit board by rotating.

[0062] Specifically, in order to remove the smoke generated by laser etching inside the frame 1, the conveying mechanism also includes a conveying fan 8, which is fixedly installed on the outer surface of the frame 1. The outlet of the conveying fan 8 is fixedly connected to the outer surface of the frame 1 through an outlet pipe. A suction fan 81 is fixedly installed on the outer surface of the frame 1, and the outlet of the suction fan 81 is fixedly connected to the outer surface of the frame 1 through an outlet pipe. The inlets of the conveying fan 8 and the suction fan 81 are respectively fixedly connected to inlet pipes 82 with filter layers. The suction fan 81 sucks the smoke inside the frame 1 through the outlet pipe fixedly connected to the frame 1 and discharges it into the air through the inlet pipe 82 fixedly connected to it. The filter layer in the inlet pipe 82 filters the smoke. At the same time, the conveying fan 8 fixedly installed on the frame 1 is activated, and the inlet pipe 82 with filter layer sucks in air and delivers it to the frame 1, which is fixedly connected to its outlet through an outlet pipe, so as to remove the smoke generated by laser etching inside the frame 1.

[0063] Specifically, to enable the cleaning brush 94 to rotate on its own axis while revolving around the center, the cleaning mechanism also includes a cleaning plate 9. The outer surface of the cleaning plate 9 is fixedly installed to the outer surface of the frame 1 by bolts. A circular frame 91 with gears is fixedly installed on the outer surface of the cleaning plate 9. A cleaning motor 92 is fixedly installed on the inner wall of the cleaning plate 9. A cleaning frame 93 is fixedly installed on the output shaft of the cleaning motor 92. The outer surface of the cleaning frame 93 is rotatably connected to the outer surface of the cleaning brush 94. A cleaning gear 95 is fixedly installed on the outer surface of the cleaning brush 94. The cleaning gear 95 meshes with the gear on the circular frame 91. The cleaning plate 9 is fixedly installed to the frame 1 by bolts so that the cleaning brush 94 can be cleaned after disassembly, and the cleaning fluid can be replaced at the same time. The cleaning motor 92 drives the cleaning frame 93 to rotate, causing the cleaning brush 94, which is rotatably connected to it, to revolve around the center. Since the cleaning gear 95 fixedly installed on the cleaning brush 94 meshes with the gear on the circular frame 91, it drives the brush to rotate on its own axis. At the same time, the position of the circuit board adsorbed on the vacuum suction cup 64 can be adjusted by the adjustment mechanism to ensure thorough cleaning.

[0064] like Figures 1-14 As shown, the present invention proposes a method for processing circuit board processing equipment, which includes the following steps:

[0065] S1: When it is necessary to move the fixing mechanism above the circuit board, start the moving motor 2 to drive the drive gear 21 to rotate, drive the electromagnet 22 to de-energize, drive the spring 23 to reset the drive gear 21 and mesh with the moving gear 26, drive the moving screw 24 to rotate, drive the sleeve 27 threaded to rotate and move, cause the moving rod 28 rotatably connected to it to move, thereby driving the moving frame 3 rotatably connected to the moving rod 28 to move above the circuit board.

[0066] S2: When the circuit board needs to be gripped, the hydraulic cylinder 41 is activated. The telescopic rod of the hydraulic cylinder 41 drives the telescopic frame 42, which is fixedly installed thereto, to move downward within the groove of the slidingly inserted fixed frame 4. Since the telescopic frame 42 is slidably inserted with the roller 46, the downward movement of the telescopic frame 42 causes the roller 46 to drive the fixed block 44, which is rotatably connected thereto, to expand. The sensor 43, which is fixedly installed with the telescopic frame 42, senses the circuit board below and adjusts the distance between the fixing mechanism and the circuit board. At the same time, the electromagnet 22 is energized, and the drive gear 21 moves and meshes with the rotating gear 31, causing the fixed rod 25 to rotate. The rotating gear 32, which is fixedly installed on the fixed rod 25, rotates. The rotating gear 32 meshes with the gear of the moving rod 28, driving the moving rod 28, which is rotatably connected to the sleeve 27, to rotate. The moving rod 28 drives the lifting screw 34, which is rotatably connected to the moving frame 3, to rotate through the bevel gear set, causing the lifting rod 33, which is threaded to it, to rotate and move. This causes the fixed frame 4, which is rotatably connected to the lifting rod 33, to descend to the designated position. When the extension rod of the hydraulic cylinder 41 drives the extension frame 42 to rise, the fixed spring 45, which is fixedly installed on the fixed frame 4, resets the fixed block 44, which is slidably sleeved with it, and grips the circuit board.

[0067] S3: When it is necessary to seal the frame 1, the circuit board is placed on the vacuum suction cup 64 by the gripping device, and the vacuum suction cup 64 is activated to adsorb and fix it. At the same time, the adjustment motor 5 is activated to drive the adjustment gear 51 and the opening and closing electromagnet 72 to rotate. The opening and closing electromagnet 72 is energized, which causes the synchronous wheel 7, which is magnetically connected to it through the adsorption component and is rotatably connected to it, to rotate. The synchronous wheel 7, which is fixedly installed with the opening and closing screw 71, is driven to rotate by the synchronous belt. The opening and closing screw 71 rotates, causing the opening and closing plate 73, which is rotatably connected to it, to move within the slidingly inserted frame 1 to seal the frame 1.

[0068] S4: When etching the circuit board through the laser instrument housing, and when adjusting the Y-axis position of the circuit board, the opening and closing electromagnet 72 is de-energized, the adjusting electromagnet 52 is de-energized, the adjusting spring 53 resets the adjusting gear 51 and engages with the transfer gear 56, driving the adjusting screw 54, which is fixedly installed with the transfer gear 56, to rotate, causing the adjusting frame 61, which is threadedly connected to it, to move on the sliding rod 6 and the rotating adjusting rod 55, simultaneously driving the adjusting screw 62, which is rotatably connected to it, and the worm gear 65, which is slidably connected to the adjusting rod 55, to move. When adjusting the X-axis position of the circuit board, the adjusting electromagnet 52 is energized at the same time, the adjusting gear 51 moves and engages with the adjusting gear 57, driving the adjusting rod 55 to rotate, and the worm gear 65 engages with the worm wheel 63, which is fixedly installed on the adjusting screw 62, driving the adjusting screw 62 to rotate, causing the vacuum suction cup 64, which is threadedly connected to it, to move on the slidingly inserted adjusting frame 61.

[0069] S5: When it is necessary to remove the smoke generated during the laser etching process inside the frame 1, start the suction fan 81 fixedly installed above the frame 1, and suck the smoke inside through the air outlet pipe fixedly connected to the frame 1, and discharge it into the air through the air inlet pipe 82 fixedly connected to the suction fan 81. The filter layer in the air inlet pipe 82 filters it. At the same time, start the conveying fan 8 fixedly installed below the frame 1, and the air inlet pipe 82 with the filter layer sucks the air and delivers it to the frame 1, which is fixedly connected to its air outlet through the air outlet pipe.

[0070] S6: When it is necessary to clean the surface of the circuit board after laser etching, start the cleaning motor 92 fixedly installed in the cleaning plate 9, so that the cleaning frame 93 fixedly installed with its output shaft rotates, driving the cleaning brush 94 rotatably connected to the cleaning frame 93 to revolve. Since the cleaning gear 95 fixedly installed on the cleaning brush 94 meshes with the gear of the circular frame 91, it rotates on its own axis to clean the circuit board.

[0071] 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.
