Description

Technical Field

[0001] This invention relates to the field of integrated circuit manufacturing technology, specifically to an electrostatic discharge (ESD) elimination device for integrated circuit boards. Background Technology

[0002] Integrated circuits are devices that combine components such as resistors and capacitors. They are used in various electronic devices. During transportation, static electricity can be generated due to friction, which can easily damage the internal circuitry of integrated circuits.

[0015] Preferably, the mounting plate is rotatably connected to two static eliminators, which are symmetrically arranged on both sides of the guide rail.

[0016] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0017] 1. This integrated circuit board static elimination device uses a drive motor to rotate a first rotating rod, which in turn drives a cleaning roller to rotate via a first spring. The anti-static brush on its outer wall can sweep dust off the surface of the circuit board. At the same time, the first rotating rod drives a second rotating rod, causing a first striking block to strike the cleaning roller, making the brush vibrate and penetrating deep into the gaps and small holes of the circuit board to remove dust, greatly improving the cleaning effect. A vacuum cleaner, in conjunction with the suction port, promptly removes dust, preventing it from flying and polluting the working environment, ensuring continuous and efficient cleaning work, and avoiding secondary contamination of the circuit board.

[0018] 2. This integrated circuit board electrostatic elimination device, by setting a bending plate and a scraper, can scrape off the stains on the surface of the circuit board during the movement of the circuit board. At the same time, the setting of the torsion spring can make the scraper better fit the surface of the circuit board, thereby improving the scraping effect.

[0019] 3. This integrated circuit board electrostatic elimination device uses a reciprocating lead screw and a second rotating rod driven by a synchronous belt pulley. The rotation of the second rotating rod drives the reciprocating lead screw to rotate, causing the scraper to move up and down to scrape away stains on the surface of the circuit board. The ball screw and ball sleeve ensure the smooth movement of the scraper. The extrusion block rotates with the ball sleeve to extrude the extrusion nozzle, spraying the cleaning agent in the water tank onto the circuit board, enhancing the scraping effect. The design of the inclined groove and drain outlet at the top of the scraper can recover excess cleaning agent, which saves resources and avoids pollution.

[0020] 4. In this integrated circuit board electrostatic elimination device, the hot air blower of the drying mechanism is installed on the lifting plate that moves up and down with the scraper. It can dry the cleaned circuit board. The movement of the lifting plate drives the moving block, which moves back and forth under the action of the wave groove, driving the second striking block to strike the circuit board, shaking off excess cleaning agent, accelerating the drying process, improving drying efficiency, and reducing the risk of short circuit or corrosion of the circuit board caused by residual moisture.

[0021] 5. This integrated circuit board static elimination device has static elimination rods symmetrically arranged on the mounting plate to eliminate static electricity on the circuit board. After the circuit board is cleaned, dirt is scraped off and dried, the static elimination rods can effectively remove residual static electricity on the surface of the circuit board.

The second rotating rod 66 is rotatably connected to the fixing frame 65, and the second rotating rod 66 is rotatably connected to the first rotating rod 62 through a gear set. The first striking block 67 is fixedly connected to the outer wall of the second rotating rod 66. A vacuum cleaner 68 is fixedly installed at the bottom of the workbench 1. The output end of the vacuum cleaner 68 is connected to a connecting pipe 69. A suction port 610 is fixedly installed on the fixing frame 65, and the suction port 610 is located on both sides of the cleaning roller 64. The other end of 9 passes through the bottom of the workbench 1 and is connected to the dust suction port 610. A curved plate 611 is fixedly connected to the fixed frame 65. A slide rod is fixedly connected to the inner wall of the curved plate 611. A scraper 612 is sleeved on the slide rod. A torsion spring 613 is provided on the slide rod, and the two ends of the torsion spring 613 are fixedly connected to the slide rod and the scraper 612 respectively. The placement seat 5 includes a fixed clamp, a movable clamp, a second spring and a second telescopic rod. The fixed clamp is fixedly connected to the top of the linear motor 4. The movable clamp is connected to the fixed clamp through the second telescopic rod. The second spring is sleeved on the second telescopic rod, and the two ends of the second spring are fixedly connected to the fixed clamp and the movable clamp respectively. A scraping mechanism 7 is provided on the workbench 1. The scraping mechanism 7 includes a reciprocating screw 71, a ball screw 72 and a scraper 73. The worktable consists of a ball sleeve 74, a water tank 75, an extrusion nozzle 76, an extrusion block 77, and a reciprocating screw 71 rotatably connected to the top of the inner wall of the worktable 1. The reciprocating screw 71 is also connected to the second rotating rod 66 via a synchronous pulley. A ball screw 72 is fixedly connected to the top of the worktable 1. A scraper 73 is threaded onto the reciprocating screw 71 and movably mounted on the ball screw 72. A ball sleeve 74 is mounted on the ball screw 72 and rotatably connected to the top of the scraper 73. A water tank 75 is fixedly connected to the bottom of the scraper 73. The extrusion nozzle 76 is mounted on the top of the scraper 73 and communicates with the water tank 75. The extrusion block 77 is fixedly connected to the outer wall of the ball sleeve 74. A groove is formed at the top of the scraper 73, and a drain outlet is formed at the bottom of the groove.Furthermore, the drain outlet is connected to the top of the water tank 75.

[0038] Working principle: The circuit board is placed on the placement base 5. The linear motor 4 is started to move the circuit board into the frame 2. The drive motor 61 is started to drive the first rotating rod 62 to rotate, which in turn drives the cleaning roller 64 to rotate through the first spring 63. The anti-static brush on the cleaning roller 64 cleans the dust on the surface of the circuit board. At the same time, the rotation of the first rotating rod 62 drives the second rotating rod 66 to rotate through the gear set, which in turn drives the first striking block 67 on the second rotating rod 66 to rotate. The first striking block 67 strikes the cleaning roller 64, causing the cleaning roller 64 to vibrate. This causes the anti-static brush on the cleaning roller 64 to vibrate, allowing the brush to better penetrate into the gaps and small holes of the circuit board and remove the dust from the gaps and small holes, improving the cleaning effect. At the same time, the vacuum cleaner 68 is started to absorb the dust generated during cleaning through the suction port 610. To prevent dust from flying, when the circuit board passes over the bending plate 611, the torsion spring 613 makes the scraper 612 on the bending plate 611 better fit the surface of the circuit board. The scraper 612 initially removes the stains on the surface of the circuit board. When the second rotating rod 66 rotates, it drives the reciprocating screw 71 to rotate through the synchronous belt pulley, thereby driving the scraper 73 to move up and down. The up and down movement of the scraper 73 further removes the stains on the surface of the circuit board. At the same time, when the scraper 73 moves up and down, the ball screw 72 drives the ball head 74 to rotate, thereby driving the extrusion block 77 to rotate. The extrusion block 77 extrudes the extrusion nozzle 76, thereby spraying the circuit board cleaning agent in the water tank 75 onto the circuit board, improving the scraping effect of the scraper 73. Excess cleaning agent flows back into the water tank 75 through the inclined groove and drain, avoiding waste.

[0039] Please see Figure 1-10 Based on the above embodiments, in another embodiment of the present invention, a drying mechanism 8 is provided on the frame 2. The drying mechanism 8 includes a lifting plate 81, a hot air blower 82, a moving block 83, a mounting plate 84, a first telescopic rod 85, a moving plate 86, a wave groove 87, and a second striking block 88. The lifting plate 81 is fixedly connected to the side of the scraper 73. The hot air blower 82 is fixedly installed on the top of the lifting plate 81. The moving block 83 is fixedly connected to the side of the lifting plate 81. The mounting plate 84 is fixedly connected to the inner wall of the frame 2. The first telescopic rod 85 is fixedly connected to the inner wall of the frame 2. The moving plate 86 is fixedly connected to the movable end of the first telescopic rod 85, and the first telescopic rod 85 is slidably connected to the mounting plate 84. The wave groove 87 is opened on the moving plate 86, and the inner wall of the wave groove 87 is slidably connected to the moving block 83. The second striking block 88 is fixedly connected to the moving plate 86. Two static elimination rods 9 are rotatably connected to the mounting plate 84 and are symmetrically arranged on both sides of the guide rail 3.

[0040] Working principle: The scraper 73 moves up and down, driving the hot air blower 82 on the lifting plate 81 to move up and down, drying the heating plate. At the same time, the up and down movement of the lifting plate 81 drives the moving block 83 to move up and down, which in turn drives the moving plate 86 to move back and forth under the action of the wave groove 87. This causes the second striking block 88 to strike the circuit board, shaking off excess cleaning agent from the circuit board and improving the drying effect. Then, the static electricity is eliminated from the circuit board by the static elimination rod 9.
