Patent application CN202021796394.3 describes a dust removal device for integrated circuit board production. Its structure includes a drive belt and an inclined work plate. A dust removal cover above the work plate houses a motor and fan blades. As the integrated circuit board slowly slides along the work plate, the fan blades blow away the dust. However, while the fan blades clean the dust on the circuit board, some dust mixes with the air, and the board still picks up dust during unloading, affecting the cleaning effect.

[0003] Based on this, the present invention designs a dust removal device for integrated circuit board production to solve the above problems. Utility Model Content

The fixing pipes are located between the corresponding side wall of the second fixing box and the filter screen.

[0009] Each of the two suction boxes has a suction port on the bottom of opposite sides, and a movable tube is fixed in the middle of the top surface. The top of the movable tube is slidably fitted into the fixed tube. Two horizontal movable plates are symmetrically arranged in the first fixed box. The top surface of the movable plate is connected to the top surface of the first fixed box by a spring. A lifting component is connected to the bottom. Vertical movable grooves are provided on the two side walls of the first fixed box at the end positions of the movable plates. Both ends of the movable plates extend out of the movable grooves and are fixedly connected to the top of the suction box on the corresponding side.

[0010] Preferably, the lifting assembly includes two cams symmetrically located on both sides of the bottom surface of the movable plate. The cams are rotatably connected to the bottom surface of the first fixed box, and a first gear is coaxially fixed on the cam. A second gear meshes with the lower inner side of the first gear. The two second gears mesh with each other, and one of the second gears is connected to a motor.

[0011] Preferably, a dust collection trough is fixed to the bottom of the filter screen near the fixed pipe, and an inclined air guide plate is fixed to the bottom of the inner cavity of the second fixed box at the position corresponding to the outer side of the dust collection trough, and the inner side of the top of the air guide plate is in contact with the top of the outer side of the dust collection trough.

[0012] Preferably, the top surface of the second fixing box has a rectangular slot corresponding to the position of the filter screen, and the top of the slot has a mounting plate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0029] Example 1

[0030] Please refer to the attached drawings. This utility model provides a technical solution: a dust removal device for integrated circuit board production, including a conveying structure and a dust removal mechanism. The conveying mechanism includes a conveying trough 1, and the dust removal mechanism is located at the top center of the conveying trough 1. Two conveying wheels are rotatably connected in the conveying trough 1. The two conveying wheels are provided with a conveyor belt 101, and one end of one of the conveying wheels is connected to a motor.

[0031] The dust removal mechanism includes a first fixed box 2 fixed in the middle of the top of the conveying trough 1, a second fixed box 3 vertically fixed in the middle of the top surface of the first fixed box 2, and two suction boxes 4 symmetrically arranged on the lower part of both sides of the first fixed box 2. The two ends of the suction boxes 4 are slidably connected to the two side walls of the conveying trough 1, and the bottom surface is in contact with the conveyor belt 101.

[0032] The first fixed box 2 has air inlet slots 201 at both ends, and a jet pipe 202 is fixed in the middle of the bottom surface along the length direction. The bottom surface of the jet pipe 202 is evenly provided with multiple air outlets along the length direction. A jet pump 204 is fixed in the middle of the bottom surface of the inner cavity of the first fixed box 2, and the fixed pipe 302 is connected to the jet pump 204.

[0033] Two vertical fixing pipes 302 are symmetrically fixed on both sides of the bottom surface of the second fixing box 3, and an air outlet groove 301 is fixed in the middle of the top surface. A suction fan 304 is fixed at the top of the inner cavity of the second fixing box 3 corresponding to the position of the air outlet groove 301, and vertical filters 305 are symmetrically fixed on both sides of the inner cavity. The fixing pipes 302 are located between the corresponding side wall of the second fixing box 3 and the filters 305.

[0034] Each of the two suction boxes 4 has a suction port 403 on the bottom of opposite sides, and a movable tube 402 is fixed in the middle of the top surface. The top of the movable tube 402 is slidably sleeved in the fixed tube 302. Two horizontal movable plates 401 are symmetrically arranged in the first fixed box 2. The top surface of the movable plate 401 is connected to the top surface of the first fixed box 2 by a spring, and a lifting assembly is connected to the bottom. Vertical movable grooves 203 are provided on both sides of the first fixed box 2 at the end positions of the movable plates 401. Both ends of the movable plates 401 extend out of the movable grooves 203 and are fixedly connected to the top of the suction box 4 on the corresponding side.

[0035] When the device is working, the integrated circuit board is evenly placed on the conveyor belt 101. The board is intermittently transported to the middle of the conveyor trough 1 by the conveyor wheel and the conveyor belt 101. At this time, there is a certain distance between the bottom surface of the suction box 4 and the top surface of the conveyor belt 101 so that the board can be smoothly transported to the bottom of the jet pipe 202. Then, the lifting assembly drives the moving plate 401 and the suction box 4 to move down, so that the bottom end of the suction box 4 contacts the conveyor belt 101. A relatively closed space is formed near the board through the two side walls of the conveyor trough 1, the two suction boxes 4 and the first fixed box 2, to prevent the dust-laden air from spreading outward during dust removal.

[0036] The circuit board is blown clean by jet pump 204 and jet pipe 202. At the same time, the suction fan 304 draws the dust-laden air after blowing into the suction box 4 through the suction port 403, and then enters the second fixed box 3 along the moving pipe 402 and the fixed pipe 302. After being filtered by the filter screen 305, it is discharged through the air outlet 301, thus completing the filtration and discharge of the dust-laden air, preventing dust from falling onto the cleaned circuit board and other structures, and ensuring the dust removal effect of the circuit board.

[0037] After each dust removal and cleaning, the lifting assembly causes the moving plate 401 to move the suction box 4 upward, and the moving pipe 402 is upward relative to the fixed pipe 302, so that the bottom end of the suction pipe is spaced a certain distance from the conveyor belt 101, so that the upper and lower circuit boards of the conveyor belt 101 can pass smoothly through the bottom end of the suction box 4 and the moving jet pipe 202 for dust removal and cleaning.

[0038] The lifting assembly includes two cams 404 symmetrically located on both sides of the bottom surface of the movable plate 401. The cams 404 are rotatably connected to the bottom surface of the first fixed box 2. A first gear 405 is coaxially fixed on the cams 404. A second gear 406 meshes with the lower inner side of the first gear 405. The two second gears 406 mesh with each other, and one of the second gears 406 is connected to a motor.

[0039] When it is necessary to move the suction box 4 upward, the motors of the two lifting components are started at the same time. Driven by the motors and the transmission of the first gear 405 and the second gear 406, the cam 404 is rotated, which causes the moving plate 401 to compress the spring and move upward, thereby moving the suction box 4 upward so that a certain space is left between the bottom surface of the suction box 4 and the conveyor belt 101, so that the circuit board can pass smoothly and continue to be conveyed backward.

[0040] The filter screen 305 has a dust collection trough 306 fixed to the bottom side near the fixed pipe 302. The bottom of the inner cavity of the second fixed box 3 is fixed with an inclined air guide plate 307 corresponding to the outer side of the dust collection trough 306. The inner side of the top of the air guide plate 307 is in contact with the top of the outer side of the dust collection trough 306. When dusty air enters the second fixed box 3 through the fixed pipe 302, the airflow moves towards the filter screen 305 through the action of the air guide plate 307. After filtration, dust and other particles fall into the dust collection trough 306 for collection and subsequent processing.

[0041] Dustproof nets are fixed in both the air inlet slot 201 and the air outlet slot 301 to prevent external dust from entering the first fixed box 2 and the second fixed box 3.

[0042] Example 2

[0043] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the top surface of the second fixing box 3 is provided with a rectangular slot corresponding to the position of the filter screen 305, and the top of the slot is provided with a mounting plate 303. The top of the filter screen 305 passes through the slot and is fixedly connected to the bottom surface of the mounting plate 303. A handle is fixed in the middle of the top surface of the mounting plate 303, and magnetic strips 309 are symmetrically fixed on both sides of the bottom surface. The top surface of the second fixing box 3 is also provided with a corresponding position of a magnetic strip 309, which is attracted and fixed to the magnetic strip 309 on the mounting plate 303, thereby fixing the position of the mounting plate 303 and closing the slot of the second fixing box 3 through the mounting plate 303.

[0044] When it is necessary to remove dust from the filter screen 305 and the dust collection tank 306, the mounting plate 303 is pulled up forcefully by the handle to disengage the magnetic strip 309 on the mounting plate 303 from the magnetic strip 309 on the second fixed box 3, thereby removing the mounting plate 303 from the second fixed box 3 so that the filter screen 305 and the dust collection tank 306 can be operated.

[0045] Example 3

[0046] The structure of this embodiment is basically the same as that of embodiment two. The difference is that a boss 308 is fixed on the bottom surface of the mounting plate 303 corresponding to the top slot of the second fixing box 3. The four sides of the boss 308 are inclined, and the four sides of the slot are correspondingly inclined surfaces and are fixed with sealing gaskets. The sides of the boss 308 are in contact with the sealing gaskets to improve the sealing performance of the mounting plate 303 to the slot.
