Description

Technical Field

[0001] The invention relates to the technical field of circuit board production, and in particular to a smear removal device used in circuit board production and a use method thereof. Background Art

[0002] The names of circuit boards include ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. During the production and processing of circuit boards, residual glue will be produced on the surface, which needs to be removed.

[0003] Patent No. CN215301055U discloses a rapid desmearing device for circuit board production, including a device body, a conveyor belt, a spraying assembly, a brush and a water spraying assembly. The surface of the device body is provided with a conveyor belt, and a spraying assembly is installed on the inner wall of the device body, and a liquid storage tank is fixed on the top of the spraying assembly. A brush rod is rotatably installed on the inner wall of the device body on one side of the spraying assembly, and a brush is set on the outer wall of the brush rod. A rubber block is fixed on the inner wall of the device body below the brush, and a water spraying assembly is installed on the inner wall of the device body on one side of the brush. A water tank is installed on the top of the device body, and a water pump is installed on one side of the water tank. This application not only improves the desmearing rate, facilitates the washing and drying of circuit boards, but also facilitates the centralized collection and discharge of sewage.

[0004] In the prior art, the circuit board is first sprayed with a spray assembly to melt the glue residue on the circuit board, and then the circuit board is cleaned with a brush. However, in the actual cleaning process, it is found that when the brush is working continuously, some glue residue will remain on the brush head due to cleaning.

At the same time, the planetary gear disc and the cleaning brush are lowered through the lifting warehouse during the movement, so that the cleaning brush fits the circuit board; S2, the cleaning brush is attached to the circuit board and the connecting gear is meshed with the driving gear, then the connecting gear is driven to rotate by the driving motor, and the planetary gear is driven to rotate by the tensioning belt and other components, and then the cleaning brush is used to clean the circuit board; S3, after cleaning is completed, the moving track drives the fixed base to leave, and in the process of leaving, the planetary gear disk is driven to descend through the lifting warehouse, so that the cleaning brush is lowered into the cleaning warehouse, and then the connecting gear is meshed with gear 2 again, and the cleaning brush is driven to rotate in the cleaning warehouse again through the rotation of gear 2, thereby realizing the self-cleaning work of the cleaning brush.

[0014] Beneficial effects of the present invention: (1) The present invention places the circuit board on a fixed base, then drives the fixed base to the bottom of the planetary gear disk, and drives the planetary gear disk to descend through the lifting chamber while the fixed base moves, so that the cleaning brush abuts against the circuit board on the fixed base, and then drives the planetary gear disk to rotate and drive the cleaning brush to clean the circuit board.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 9 As shown, the present application provides a smear removal device for circuit board production, comprising a body 1, and also comprising: A fixing mechanism 2, arranged above the body 1, for fixing the circuit board; A cleaning mechanism 4 is arranged above the fixing mechanism 2 and is used for cleaning the circuit board; The lifting mechanism 3 is arranged on both sides of the machine body 1 and is used for lifting and lowering the cleaning mechanism 4; A driving mechanism 5 is arranged on one side of the cleaning mechanism 4 and is used for driving the cleaning mechanism 4; A cleaning chamber 16 is provided in the middle of the machine body 1 and is used for cleaning the cleaning mechanism 4; A spraying bin 17 is provided on one side of the machine body 1 and is used to store the degumming liquid; The spray box 6 is arranged above the spray bin 17 and connected to the spray bin 17, and is used for spraying the circuit board; The top of the machine body 1 is fixedly connected with a moving track 11; a moving screw rod 12 is rotatably connected in the moving track 11; a connecting block 14 is threadedly connected to the moving screw rod 12; a notch 13 is opened on the side wall of the moving track 11; a connecting rack 15 is fixedly connected to the side wall of the connecting block 14; the connecting rack 15 is arranged to pass through the notch 13; During operation, in the prior art, the circuit board is first sprayed by a spraying assembly to melt the glue residue on the circuit board, and then the circuit board is cleaned by a brush. However, in the actual cleaning process, it is found that when the brush is working continuously, some glue residue will remain on the brush head due to cleaning, and more glue residue will be accumulated on the brush head after working for a long time, so that the brush head cannot provide a cleaning effect, and the cleaning efficiency of the circuit board is reduced. At the same time, when the circuit board is cleaned, since the circuit board is not fixed, the brush will drive the circuit board to move when it rotates for cleaning, so that the brush is always cleaning in one position, thereby affecting the working efficiency. In order to prevent such incidents from happening, first, the circuit board is placed on the fixing mechanism 2, and then the fixing mechanism 2 is driven by the moving track 11 to move to the bottom of the cleaning mechanism 4. While moving, the degumming liquid is sprayed onto the circuit board through the spray box 6, and then the cleaning mechanism 4 is used to clean the circuit board on the fixing mechanism 2, and then the fixing mechanism 2 is moved away from the cleaning mechanism 4. In the process of moving away, the cleaning mechanism 4 is moved to the bottom of the cleaning bin 16 by the lifting mechanism 3 to achieve cleaning of the cleaning mechanism 4.

[0022] like Figure 3-Figure 7As shown, the fixing mechanism 2 includes a fixing base 21; the bottom of the fixing base 21 is fixedly connected to the connecting block 14; the lifting mechanism 3 includes a lifting warehouse 31; the lifting warehouse 31 is fixedly connected to both sides of the machine body 1; a lifting screw 32 is rotatably connected in the lifting warehouse 31; a lifting block 33 is threadedly connected to the lifting screw 32; a lifting gear 34 is rotatably connected to the bottom of the lifting warehouse 31; the lifting gear 34 is movably engaged with the connecting rack 15; the output end of the lifting gear 34 is fixedly connected to the input end of the lifting screw 32; the cleaning mechanism 4 includes a planetary gear disc 41; fixed columns 411 are fixedly connected to both sides of the planetary gear disc 41; the fixed columns 411 The planetary gear 42 and the middle gear 43 are connected to each other in rotation in the planetary gear disc 41; the planetary gear 42 is distributed around the middle gear 43; the planetary gear 42 is provided with four groups; a cleaning column 44 and a sliding column 45 are provided at the bottom of the planetary gear 42; the cleaning column 44 is connected to the planetary gear 42 and penetrates the planetary gear disc 41; a sliding groove 451 is provided at the connection between the sliding column 45 and the cleaning column 44; a telescopic spring 452 is fixedly connected in the sliding groove 451; the end of the telescopic spring 452 away from the sliding groove 451 is fixedly connected to the cleaning column 44; the end of the sliding column 455 away from the cleaning column 44 is fixedly connected to the cleaning brush 46; During operation, after the circuit board is placed on the fixed base 21, the moving screw rod 12 in the moving track 11 is driven to rotate. During the rotation, the fixed base 21 is driven to move toward the planetary gear disk 41 through the connecting block 14. During the movement, the connecting rack 15 on the side wall of the connecting block 14 will mesh with the lifting gear 34 at the bottom of the lifting warehouse 31 as it moves. After meshing, the fixed base 21 continues to move, and the connecting rack 15 is used to drive the lifting gear 34 and the lifting column to rotate. During the rotation, the lifting column drives the fixed column 411 and the planetary gear disk 41 to descend through the lifting block 33, thereby driving the cleaning column 44 and the cleaning brush 46 at the bottom of the sliding column 45 to descend. When the fixed base 21 reaches the bottom of the planetary gear disk 41, the cleaning brush 46 abuts against the circuit board on the fixed base 21, and drives the middle gear 43 to rotate after abutment. During the rotation, the middle gear 43 drives the surrounding planetary gears 42 to rotate in the planetary gear disk 41, thereby driving The movable cleaning brush 46 performs cleaning work on the circuit board. When the cleaning work is completed, the fixed base 21 needs to continue to move. During the movement, the connected rack 15 will also drive the lifting screw rod 32 to rotate, and when it rotates again, the planetary gear disc 41 will drop again. When it drops again, due to the obstruction of the circuit board, the cleaning column 44 will squeeze the telescopic spring 452 in the sliding column 45, so that the overall length of the cleaning column 44 and the sliding column 45 becomes shorter. Through the telescopic cleaning column 44 and the sliding column 45, it can be avoided that the cleaning brush 46 and the circuit board will not come into hard contact when it drops again, causing damage to the circuit board. Through the setting of the telescopic spring 452, it can play a buffering role when the cleaning brush 46 drops again. When the fixed base 21 is away from the planetary gear disc 41, the telescopic spring 452 rebounds, causing the sliding column 45 and the cleaning column 44 to return to their original length. At the same time, the planetary gear disc 41 continues to drop, so that the cleaning brush 46 reaches the cleaning bin 16 below for cleaning.

[0023] like Figure 5 As shown, the driving mechanism 5 includes a driving plate 51; the driving plate 51 is fixedly connected to one side of the lifting warehouse 31; a driving column 52 is rotatably connected to the middle part of the driving plate 51; a driving motor 53 is fixedly connected to the end of the driving column 52 away from the driving plate 51; the driving column 52 is driven to rotate by the driving motor 53; a driving gear 521 is fixedly connected to the driving column 52; a cleaning gear 47 is rotatably connected to the planetary gear 41; the output end of the cleaning gear 47 is fixedly connected to the input end of the middle gear 43; side gears 471 and connecting gears 48 are rotatably provided on the planetary gears 41 on both sides of the cleaning gear 47; a tensioning belt 49 is sleeved on the side gear 471 and the cleaning gear 47; the connecting gear 48 is movably meshed with the driving gear 521; During operation, when the planetary gear 42 descends and the cleaning brush 46 abuts against the circuit board, the connecting gear 48 on the planetary gear disc 41 will mesh with the driving gear 521, and then the driving motor 53 will drive the driving gear 521 to rotate, and then drive the connecting gear 48 to rotate. When the connecting gear 48 rotates, it will drive the side gear 471 to rotate, and then drive the cleaning gear 47 to rotate through the tensioning belt 49, and then drive the middle gear 43 to rotate, thereby realizing the rotation of the cleaning brush 46, and the cleaning brush 46 will be used to clean the circuit board.

[0024] like Figure 5 As shown, a stirring column 171 is rotatably connected in the spraying bin 17; a stirring rod 172 is fixedly connected to the stirring column 171; a partition 19 is fixedly connected to the side wall of the body 1 at the top of the spraying bin 17; a connecting column 173 and a gear 174 are rotatably provided on the partition 19; the input end of the connecting column 173 is fixedly connected to the output end of the stirring column 171; a connecting belt 1731 is sleeved on the gear 174 and the connecting column 173; a connecting plate 176 is fixedly connected to the side wall of the body 1; a gear 2 175 is rotatably connected to the middle of the connecting plate 176; the gear 2 175 is meshedly connected to the gear 1 174; the end of the gear 2 175 away from the gear 1 174 is movably meshed with the connecting gear 48; When working, the fixed base 21 continues to move after cleaning is completed, so that the fixed base 21 moves to the very end of the machine body 1, thereby facilitating the disassembly of the circuit board. After the fixed base 21 is away from the cleaning brush 46, the cleaning brush 46 will drop into the cleaning chamber 16 below. When the fixed base 21 reaches the very end of the machine body 1, the planetary gear disc 41 will drop to the lowest point. At the same time, the connecting gear 48 on the planetary gear disc 41 will mesh with the gear 2 175, and when the planetary gear 42 drops to the lowest point, the stirring column 171 in the spray chamber 17 is driven to rotate, and the connecting column 173 will be driven to rotate during rotation, and then the connecting belt 1731 on the connecting column 173 drives the gear 1 174 to rotate. When the gear 1 174 rotates, it will drive the gear 2 175 to rotate, and then the connecting gear 48 will be driven to rotate through the gear 2 175, thereby driving the cleaning brush 46 to rotate in the cleaning chamber 16 again, and the cleaning of the cleaning brush 46 is realized. In addition, through the setting of the stirring column 171, the degumming liquid in the spray chamber 17 can be stirred to prevent the degumming liquid from solidifying.

[0025] like Figure 8 and Fig. 9As shown, a crown gear 23 is rotatably connected inside the fixed base 21; a middle plate 24 is fixedly connected to the side wall of the fixed base 21 above the crown gear 23; a bidirectional screw rod 25 is rotatably connected to the side wall of the middle plate 24; a driven gear 251 is fixedly connected to the bidirectional screw rod 25; the driven gear 251 is meshingly connected with the crown gear 23; a moving plate 26 is threadedly connected to the bidirectional screw rod 25; a clamping plate 27 is fixedly connected to the end of the moving plate 26 away from the bidirectional screw rod 25; the clamping plate 27 is arranged above the fixed base 21; an anti-slip pad 211 is fixedly connected to the fixed base 21; a transmission gear 22 is rotatably connected to the bottom of the fixed base 21; the output end of the transmission gear 22 is fixedly connected to the input end of the crown gear 23; a side tooth 111 is fixedly connected to the side wall of the movable track 11; the side tooth 111 is meshingly connected with the transmission gear 22; During operation, when the fixed base 21 is driven to move by the connecting block 14, the transmission gear 22 at the bottom will be driven to rotate by the side teeth 111, thereby driving the crown gear 23 inside the fixed base 21 to rotate. When the crown gear 23 rotates, it will drive the driven gear 251 above to rotate, thereby driving the bidirectional screw rod 25 to rotate. When the bidirectional screw rod 25 rotates, it will drive the two sets of movable plates 26 to move. After the circuit board is placed on the fixed base 21, the movable plate 26 will drive the clamping plate 27 to move toward the circuit board while the fixed base 21 moves. When the fixed base 21 moves below the planetary gear disc 41, the clamping plate 27 clamps the circuit board, and then starts cleaning. After the cleaning work is completed, when the fixed base 21 moves again, the clamping plate 27 will be driven by the bidirectional screw rod 25 to move in the opposite direction, thereby releasing the fixation of the circuit board, which is convenient for subsequent removal.

[0026] like Figure 2 As shown, the side wall of the moving track 11 is fixedly connected to a moving motor 112; the moving screw rod 12 is driven by the moving motor 112; the bottom of the machine body 1 is fixedly connected to a spraying motor 18; the stirring column 171 is driven by the spraying motor 18; During operation, the movable screw 12 can be driven to rotate by the movable motor 112, thereby driving the fixed base 21 to move, and the stirring column 171 can be driven to rotate by the spraying motor 18, thereby driving the cleaning brush 46 to clean in the cleaning chamber 16.

[0027] like Figure 8 As shown, the anti-slip pad 211 is made of rubber; During operation, the anti-skid pad 211 made of rubber material can prevent the circuit board from sliding when it is placed on the fixed base 21 , thereby facilitating the cleaning work of the cleaning brush 46 .

[0028] See also Figure 1-Figure 9 As shown, the present application provides a method for using a smear removal device for circuit board production, comprising the following steps: S1, first, place the circuit board on the fixed base 21, then use the movable track 11 to drive the fixed base 21 to move to the bottom of the planetary gear plate 41, and during the movement, use the transmission gear 22 and other components to clamp the circuit board, and at the same time, use the lifting warehouse 31 to lower the planetary gear plate 41 and the cleaning brush 46 during the movement, so that the cleaning brush 46 fits the circuit board; S2, the cleaning brush 46 is attached to the circuit board while the connecting gear 48 is meshed with the driving gear 521, then the connecting gear 48 is driven to rotate by the driving motor 53, and the planetary gear 42 is driven to rotate by the tensioning belt 49 and other components, and then the cleaning brush 46 is used to clean the circuit board; S3, after cleaning is completed, the moving track 11 drives the fixed base 21 to leave, and in the process of leaving, the planetary gear 41 is driven to descend through the lifting chamber 31, so that the cleaning brush 46 descends into the cleaning chamber, and then the connecting gear 48 is meshed with the gear 2 175 again, and the cleaning brush 46 is driven to rotate in the cleaning chamber again through the rotation of the gear 2 175, so as to realize the self-cleaning work of the cleaning brush 46; During operation, first, the circuit board is placed on the fixed base 21, and then the fixed base 21 is driven by the movable track 11 to move to the bottom of the planetary gear disk 41. During the movement, the circuit board is clamped by components such as the transmission gear 22. At the same time, the planetary gear disk 41 and the cleaning brush 46 are lowered through the lifting warehouse 31 during the movement, so that the cleaning brush 46 is fitted with the circuit board. While the cleaning brush 46 is fitted with the circuit board, the connecting gear 48 is meshed with the driving gear 521. Then, the connecting gear 48 is driven to rotate by the driving motor 53, and the planetary gear 42 is driven to rotate by components such as the tensioning belt 49, and then the cleaning brush 46 is used to clean the circuit board. After cleaning, the movable track 11 drives the fixed base 21 to leave. During the leaving process, the planetary gear disk 41 is driven to descend by the lifting warehouse 31, so that the cleaning brush 46 is lowered into the cleaning warehouse, and then the connecting gear 48 is meshed with the gear 2 175 again, and the cleaning brush 46 is driven to rotate in the cleaning warehouse again through the rotation of the gear 2 175, so as to realize the self-cleaning work of the cleaning brush 46.

[0029] The working principle of the present invention is as follows: after the circuit board is placed on the fixed base 21, the moving screw rod 12 in the moving track 11 is driven to rotate, and the fixed base 21 is driven to move toward the planetary gear disk 41 through the connecting block 14 during rotation. During the movement, the connecting rack 15 on the side wall of the connecting block 14 will mesh with the lifting gear 34 at the bottom of the lifting bin 31 as it moves. After meshing, the fixed base 21 continues to move, and the connecting rack 15 is used to drive the lifting gear 34 and the lifting column to rotate. During rotation, the lifting column drives the fixed column 411 and the planetary gear disk 41 to descend through the lifting block 33, thereby driving the cleaning column 44 and the cleaning brush 46 at the bottom of the sliding column 45 to descend. When the fixed base 21 reaches directly below the planetary gear disk 41, the cleaning brush 46 abuts against the circuit board on the fixed base 21, and after abutting, the middle gear 43 is driven to rotate. During rotation, the middle gear 43 drives the surrounding planetary gears 42 to rotate in the planetary gear disk 41, thereby After the cleaning brush 46 is lowered, the cleaning brush 46 can be prevented from making a hard contact with the circuit board when the cleaning brush 46 is lowered again.

[0030] Among them, when the fixed base 21 is driven to move by the connecting block 14, the transmission gear 22 at the bottom will be driven to rotate by the side teeth 111, thereby driving the crown gear 23 inside the fixed base 21 to rotate. When the crown gear 23 rotates, it will drive the driven gear 251 above to rotate, thereby driving the bidirectional screw rod 25 to rotate. When the bidirectional screw rod 25 rotates, it will drive the two sets of movable plates 26 to move. After the circuit board is placed on the fixed base 21, the movable plate 26 will drive the clamping plate 27 to move toward the circuit board while the fixed base 21 moves. When the fixed base 21 moves below the planetary gear disk 41, the clamping plate 27 clamps the circuit board, and then starts the cleaning work. After the cleaning work is completed, when the fixed base 21 moves again, the clamping plate 27 will be driven by the bidirectional screw rod 25 to move in the opposite direction, thereby releasing the fixation of the circuit board, which is convenient for subsequent removal.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
