Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle circuit board production, and particularly relates to a cleaning and impurity removal device for new energy vehicle circuit board production. Background Art

[0002] In the new energy vehicle industry, as a core component of the electronic control system, the quality and reliability of the circuit board are directly related to the performance and safety of the entire vehicle. During the production process of the circuit board, due to the needs of processes such as soldering and assembly, various contaminants are often attached, such as flux residues, dust, metal particles, grease, etc. These contaminants not only affect the appearance quality of the circuit board but may also cause problems such as circuit short circuits and signal interference, seriously reducing the reliability and service life of the circuit board. Therefore, the cleaning and impurity removal process after circuit board production is particularly important.

[0003] A Chinese patent with the publication number CN113714180B discloses a circuit board cleaning device for new energy vehicles, including: a base and a housing bracket, with a housing bracket provided on the upper part of the base; a fixed baffle, with a fixed baffle provided on the housing bracket; a support frame, with a support frame provided on the upper part of the base; sliding guide rails, with sliding guide rails slidably provided on both sides of the support frame; a support table, with a support table connected between the tops of the two sliding guide rails; a liquid storage tank, with a liquid storage tank provided on the upper side of the housing bracket; a cleaning mechanism, with a cleaning mechanism provided on the housing bracket; a liquid spraying mechanism, with a liquid spraying mechanism provided on the lower part of the liquid storage tank. Although the above patent can clean and remove impurities from the circuit board, for parts that are difficult to reach, such as circuit board gaps and component pins, it is difficult to thoroughly clean them only by brushing, and the brushing effect is often limited. It is impossible to dissolve or peel off the impurities on the difficult-to-reach parts through soaking to complete the stage cleaning, resulting in incomplete and non-thorough cleaning and impurity removal of the circuit board, affecting the cleaning and impurity removal effect.

[0004] The present invention aims to solve the problems existing in the above patent. For this purpose, a cleaning and impurity removal device for new energy vehicle circuit board production is proposed, which can soak and dissolve impurities on the circuit board and then complete the brushing process, with comprehensive and thorough cleaning and impurity removal, improving the cleaning and impurity removal effect. Summary of the Invention

[0005] In order to overcome the disadvantages that although the above patent can clean and remove impurities from the circuit board, for parts that are difficult to reach, such as circuit board gaps and component pins, it is difficult to thoroughly clean them only by brushing, and the brushing effect is often limited. It is impossible to dissolve or peel off the impurities on the difficult-to-reach parts through soaking to complete the stage cleaning, resulting in incomplete and non-thorough cleaning and impurity removal of the circuit board, affecting the cleaning and impurity removal effect, the present invention provides a cleaning and impurity removal device for new energy vehicle circuit board production, which can soak and dissolve impurities on the circuit board and then complete the brushing process, with comprehensive and thorough cleaning and impurity removal, improving the cleaning and impurity removal effect.

[0006] The present invention is achieved through the following technical means: A cleaning and impurity removing device for the production of a circuit board of a new energy vehicle, comprising a frame body and a water pump installed on the frame body. The water outlet end of the water pump is connected with a hose, and the tail end of the hose slidably penetrates through the frame body. A spray head is fixedly connected between the tail ends of the hoses. An opening is formed on the frame body for the circuit board after cleaning and impurity removal to pass through. An electronically controlled drain pipe is installed on the frame body. It further includes eight belt pulleys rotatably connected to both sides of the frame body. A flat belt is wound around the eight belt pulleys. The flat belt forms a concave shape through the eight belt pulleys. U-shaped plates are fixedly connected at equal intervals between the flat belts. A clamping assembly is arranged on the U-shaped plate for clamping and fixing the circuit board. Driving rods are symmetrically and fixedly connected inside the opening. The front side of the driving rod is inclined to drive the clamping assembly to operate and loosen the circuit board. A driving motor is installed on the frame body. The end of the output shaft of the driving motor is fixedly connected to the end of one of the belt pulleys. The driving motor is used to drive the belt pulley to rotate forward intermittently. The belt pulley drives the flat belt to rotate forward intermittently. The flat belt drives the circuit board to move backward intermittently through the U-shaped plate and the clamping assembly, so that the circuit board is first immersed in the cleaning agent and then washed. A brushing assembly is arranged inside the frame body for brushing the immersed circuit board.

[0007] Further explanation, the clamping assembly includes internal spline cylinders symmetrically and rotatably connected to the U-shaped plate. A spline shaft is slidably connected inside the internal spline cylinder. A return spring is connected between the end of the spline shaft and the internal spline cylinder. A clamping plate is fixedly connected to the end of the spline shaft for clamping and fixing the circuit board. Contact rods corresponding to the driving rods are symmetrically and fixedly connected to the top and bottom of the clamping plate. A straight gear is fixedly sleeved on the internal spline cylinder. The straight gear rotatably penetrates through the U-shaped plate. U-shaped racks corresponding to the straight gear are fixedly connected to both sides inside the frame body.

[0008] Further explanation, the brushing assembly includes an n-shaped seat slidably connected inside the frame body. The n-shaped seat is fixedly connected to the spray head. A soft brush is vertically slidably connected inside the n-shaped seat for brushing the circuit board. A hard brush is vertically slidably connected inside the n-shaped seat in front of the soft brush for brushing the circuit board. An electric lead screw threadedly connected to the n-shaped seat is installed inside the frame body. A switching assembly is arranged on the n-shaped seat for driving the hard brush and the soft brush to move to complete the switching.

[0009] Further explanation, the switching assembly includes guide racks fixedly connected to the soft brush and the hard brush. A gear shaft meshing with the guide rack is rotatably connected to the n-shaped seat. A worm wheel is fixedly sleeved on the gear shaft. A stepping motor is installed on the n-shaped seat.

[0010] Further description, the cleaning and impurity removal equipment for new energy vehicle circuit board production further includes a guiding component. The guiding component includes a box body fixedly connected to the frame body. The box body corresponds to the opening. A perforated plate is fixedly connected between the box body and the opening, which is used to receive and guide the dropped circuit board. The perforated plate is inclined. A hot air fan is installed on the box body, which is used to dry the circuit board after cleaning and impurity removal.

[0011] Further description, the cleaning and impurity removal equipment for new energy vehicle circuit board production further includes a water blocking component. The water blocking component includes fixed rings symmetrically fixedly connected to the n-shaped seat. Guide rods are slidably inserted through the fixed rings at equal intervals along the circumferential direction. A water blocking roller is fixedly connected between the corresponding ends of the guide rods, which is used to block part of the water. A connecting spring is connected between the guide rod and the fixed ring. A triggering component is arranged on the fixed ring, which is used to drive the water blocking roller to move.

[0012] Further description, the triggering component includes an annular disc fixedly connected to one of the fixed rings. One-word holes are evenly spaced along the circumferential direction on the annular disc. An external gear ring is fixedly connected to the outer side surface of the annular disc along the circumferential direction. A servo motor is installed on one of the fixed rings. The end of the output shaft of the servo motor is fixedly connected with a driving gear meshing with the external gear ring. A fixed rod is fixedly connected to the end of the water blocking roller, and the fixed rod is slidably connected in the one-word hole.

[0013] Further description, the cleaning and impurity removal equipment for new energy vehicle circuit board production further includes balls rotatably connected to the top of the perforated plate at equal intervals, which are used to guide the circuit board.

[0014] The remarkable progress of the present invention lies in: 1. First, start the driving motor to drive the pulley to rotate forward intermittently. The pulley drives the flat belt to rotate forward intermittently. The flat belt drives the U-shaped plate to rotate forward intermittently. The U-shaped plate drives the clamping plate to rotate forward intermittently through the internal spline cylinder and the spline shaft. The clamping plate drives the circuit board to move backward intermittently. The circuit board moves backward and first contacts the cleaning agent in the frame body for soaking treatment. Most of the impurities on the circuit board are dissolved or peeled off by the soaking method, effectively removing the impurities in the difficult-to-reach parts of the circuit board. Subsequently, the soaked circuit board moves intermittently to the brushing area and is brushed by the hard brush and the soft brush. Repeating like this, the circuit board can be continuously soaked and then brushed, and the cleaning and impurity removal are more comprehensive and thorough, thereby improving the cleaning and impurity removal effect.

[0015] 2. Under the switching of the soft brush and the hard brush, most of the impurities on the circuit board can be removed first, and then the stubborn impurities can be removed. In this way, the cooperation of the hard brush and the soft brush can brush the circuit board cleaner.

[0016] 3. Under the action of the water baffle roller, part of the water sprayed by the nozzle can be blocked, so that the water is blocked and then used to wash the circuit board. In this way, it can prevent some circuit boards from being damaged due to the inability to withstand the relatively strong water spray force, thereby improving the safety of circuit board washing.

U-shaped racks 62 are fixedly connected to the upper rear sides of the left and right inner sides of the frame body 1. The U-shaped racks 62 correspond to the spur gears 61.

[0033] Please refer to Figure 6 and Figure 7As shown in the figure, the brushing assembly includes an n-shaped seat 7, an electric lead screw 71, a hard brush 74, a soft brush 75 and a switching assembly. The top inside the frame 1 is slidably connected with the n-shaped seat 7. The upper part of the front side of the n-shaped seat 7 is fixedly connected with the nozzle 102. The soft brush 75 is vertically slidably connected inside the n-shaped seat 7, and the soft brush 75 can brush the circuit board. The hard brush 74 is vertically slidably connected inside the n-shaped seat 7. The hard brush 74 is located on the front side of the soft brush 75, and the hard brush 74 can brush the circuit board. The electric lead screw 71 is installed on the left side of the top inside the frame 1. The electric lead screw 71 is threadedly connected with the left side of the n-shaped seat 7. A switching assembly is arranged on the right side of the n-shaped seat 7. When the switching assembly operates, the switching assembly can drive the hard brush 74 and the soft brush 75 to move to complete the switching. The switching assembly includes a guide rack 76, a gear shaft 77, a worm gear 78, a worm 79 and a stepping motor 710. Guide racks 76 are fixedly connected to the right sides of both the soft brush 75 and the hard brush 74. The middle of the right side of the n-shaped seat 7 is rotatably connected with a gear shaft 77. The gear shaft 77 meshes with the guide racks 76 on the front and back sides. A worm gear 78 is fixedly sleeved on the right side of the gear shaft 77. The stepping motor 710 is installed on the right side of the n-shaped seat 7. The end of the output shaft of the stepping motor 710 is fixedly connected with a worm 79. The worm 79 meshes with the worm gear 78.

[0034] Please refer to Figure 8 As shown in the figure, the cleaning and impurity removing equipment for the production of new energy vehicle circuit boards further includes a guiding assembly installed on the frame 1. The guiding assembly includes a perforated plate 8, a box body 82 and a hot air fan 83. The upper part of the rear side outside the frame 1 is fixedly connected with the box body 82. The box body 82 corresponds to the opening 103. A perforated plate 8 is fixedly connected between the bottom inside the box body 82 and the bottom of the opening 103. The perforated plate 8 can receive and guide the dropped circuit boards. The perforated plate 8 is inclined. The hot air fan 83 is installed in the middle of the top of the box body 82. When the hot air fan 83 is started, the hot air fan 83 can dry the circuit boards after cleaning and impurity removing.

[0035] Initially, the water pump 101 is connected to an external water source. First, an appropriate amount of cleaning agent is poured into the frame 1, and the cleaning agent is made to be higher than the concave position of the flat belt 2. Then, the two front-upper clamping plates 6 are pulled outwards. The outward movement of the clamping plates 6 drives the spline shaft 64 to move outwards, and the return spring 65 is compressed. Subsequently, the circuit board is moved between the two front-upper clamping plates 6. The two front-upper clamping plates 6 are released. Due to the action of the return spring 65, the spline shaft 64 drives the two front-upper clamping plates 6 to move inwards to contact the circuit board, and the two front-upper clamping plates 6 clamp and fix the circuit board. Subsequently, the driving motor 5 is started to rotate intermittently in the forward direction. The driving motor 5 drives the belt pulley 4 to rotate intermittently in the forward direction. The belt pulley 4 drives the flat belt 2 to rotate intermittently in the forward direction. The intermittent forward rotation of the flat belt 2 drives the U-shaped plate 3 to rotate intermittently in the forward direction. The U-shaped plate 3 drives the spline shaft 64 and the straight gear 61 to rotate in the forward direction through the internal spline barrel 63. The spline shaft 64 drives the clamping plate 6 to rotate intermittently in the forward direction. When the next set of clamping plates 6 rotates to the front-upper position, the above operation can be performed to continue placing the next circuit board for clamping and fixing. Repeating this way, continuous feeding can be achieved. At the same time, when the clamping plate 6 rotates intermittently in the forward direction and drives the circuit board to move backward to the concave position of the flat belt 2, the circuit board comes into contact with the cleaning agent in the frame 1, and the circuit board is immersed in the cleaning agent. Most of the impurities on the circuit board are dissolved or peeled off by soaking, effectively removing the impurities in the hard-to-reach parts of the circuit board. Subsequently, the soaked circuit board is driven by the flat belt 2 to rotate forward again. When the soaked circuit board rotates to the brushing area, the circuit board is separated from the cleaning agent in the frame 1. At this time, the water pump 101 is started to pump water into the hose 1011, and the water in the hose 1011 is discharged into the nozzle 102, and the nozzle 102 sprays the water. Then, the electric lead screw 71 is started to rotate in the forward direction. The forward rotation of the electric lead screw 71 drives the N-shaped seat 7 to move forward. The forward movement of the N-shaped seat 7 drives the soft brush 75, the hard brush 74, and the nozzle 102 to move forward. The forward movement of the nozzle 102 sprays water on the circuit board, thereby performing a flushing treatment on the circuit board. At the same time, the soft brush 75 moves forward to contact the soaked circuit board, and the soft brush 75 first carefully brushes the circuit board to remove most of the impurities on the circuit board. When the N-shaped seat 7 moves forward to the maximum stroke, the stepping motor 710 is started to drive the worm 79 to rotate. The worm 79 drives the worm wheel 78 to rotate. The worm wheel 78 drives the gear shaft 77 to rotate. The gear shaft 77 drives the front guide rack 76 to move downward. The downward movement of the front guide rack 76 drives the hard brush 74 to move downward to contact the circuit board. At the same time, the rear guide rack 76 moves upward to drive the soft brush 75 to move upward to separate from the circuit board. In this way, the switching between the hard brush 74 and the soft brush 75 is completed. Through the self-locking effect of the worm 79 and the worm wheel 78, the locking of the gear shaft 77 can be completed, which also locks the hard brush 74 and the soft brush 75. Subsequently, the electric lead screw 71 rotates in the reverse direction to drive the N-shaped seat 7 to move backward. The N-shaped seat 7 drives the hard brush 74 and the soft brush 75 to move backward. The backward movement of the hard brush 74 removes the remaining stubborn impurities on the circuit board. Thus,The cooperation of the hard brush 74 and the soft brush 75 can brush the circuit board more cleanly. After the n-shaped seat 7 moves backward and resets, the electric lead screw 71 is turned off. Subsequently, the flat belt 2 continues to intermittently rotate forward, causing the clamping plate 6 to drive the circuit board after cleaning and impurity removal to move backward until the spur gear 61 moves to engage with the U-shaped rack 62. The U-shaped rack 62 drives the spur gear 61 that is moving backward to rotate. The rotation of the spur gear 61 drives the internal spline cylinder 63 to rotate 180 degrees. The internal spline cylinder 63 drives the clamping plate 6 to rotate 180 degrees through the spline shaft 64. The clamping plate 6 drives the circuit board to rotate 180 degrees to complete turning over, making the other side face upward. The spur gear 61 continues to move until it disengages from the U-shaped rack 62. Subsequently, the electric lead screw 71 is started again according to the above operation, causing the soft brush 75 and the hard brush 74 to move to brush the side of the circuit board that has not been cleaned and impurity removed. In this way, a comprehensive cleaning and impurity removal of the circuit board can be completed, and the next circuit board can be moved backward to the brushing area for cleaning and impurity removal. Repeating this process, the circuit board can be soaked and then brushed continuously, and the cleaning and impurity removal are more comprehensive and thorough, thereby improving the effect of cleaning and impurity removal. Subsequently, the flat belt 2 continues to intermittently rotate forward, and the clamping plate 6 drives the circuit board after comprehensive cleaning and impurity removal to move backward. When the clamping plate 6 drives the contact rod 66 to move to contact the inclined position of the driving rod 67, the driving rod 67 drives the contact rods 66 on both sides to move outward. The contact rods 66 on both sides drive the clamping plates 6 on both sides to move outward. The clamping plates 6 drive the spline shafts 64 on both sides to move outward, and the return springs 65 are compressed. The clamping plates 6 on both sides move outward to release the circuit board after cleaning and impurity removal. The released circuit board falls onto the perforated plate 8. Due to the inclined setting of the perforated plate 8, the circuit board slides through the opening 103 and falls into the box body 82. The hot air fan 83 is started, and the hot air fan 83 dries the circuit board on the perforated plate 8. The water that drops during the drying process can pass through the perforated plate 8 and fall downward. The dried circuit board slides off the perforated plate 8 and is collected. As the contact rod 66 continues to rotate forward and disengages from the driving rod 67, due to the action of the return spring 65, the spline shaft 64 drives the clamping plates 6 on both sides to move inward and reset. When all the circuit boards have completed cleaning and impurity removal, the water pump 101, the drive motor 5, and the hot air fan 83 are turned off. The flat belt 2 stops intermittently rotating forward, and the clamping plate 6 also stops intermittently rotating forward. The electric control drain pipe 1012 is started to drain all the cleaning agent in the frame 1.,

[0036] Please refer to Figures 9 - 11As shown in the figure, the cleaning and impurity removal equipment for the circuit board of new energy vehicles further includes a water blocking component installed on the n-shaped seat 7. The water blocking component includes a fixing ring 9, guide rods 91, water blocking rollers 92, connecting springs 921 and a triggering component. On the lower part of the n-shaped seat 7, fixing rings 9 are symmetrically and fixedly connected to the left and right. Three guide rods 91 are slidably inserted through the fixing ring 9 at equal intervals along the circumference. A water blocking roller 92 is fixedly connected between the inner ends of the corresponding guide rods 91 on the left and right. The water blocking roller 92 can block part of the water, so that the water is buffered and then used to wash the circuit board. A connecting spring 921 is connected between the outer end of the guide rod 91 and the outer side surface of the fixing ring 9. A triggering component is arranged on the fixing ring 9. When the triggering component operates, the triggering component can drive the water blocking roller 92 to move. The triggering component includes an annular disc 93, fixing rods 95, an external gear ring 96, a servo motor 97 and a driving gear 98. An annular disc 93 is fixedly connected to the right side surface of the right fixing ring 9. Three linear holes 94 are evenly spaced along the circumference on the annular disc 93. An external gear ring 96 is fixedly connected to the outer side surface of the annular disc 93 along the circumference. A servo motor 97 is installed on the front side of the right fixing ring 9. The end of the output shaft of the servo motor 97 is fixedly connected with a driving gear 98. The driving gear 98 meshes with the external gear ring 96. Fixing rods 95 are fixedly connected to the right ends of the three water blocking rollers 92. The fixing rods 95 are slidably connected in the linear holes 94.

[0037] When it is necessary to clean and remove impurities from the circuit board, first start the servo motor 97 to drive the driving gear 98 to rotate forward and backward alternately. The driving gear 98 drives the external gear ring 96 to rotate forward and backward alternately. The external gear ring 96 drives the annular disc 93 to rotate forward and backward alternately. The annular disc 93 drives the linear holes 94 to rotate forward and backward alternately. When the linear holes 94 rotate forward, the linear holes 94 drive the three fixing rods 95 to move towards each other. The fixing rods 95 drive the three water blocking rollers 92 to move towards each other. The gap between the three water blocking rollers 92 becomes smaller. The water blocking area of the three water blocking rollers 92 for the water sprayed by the nozzle 102 is larger, so that the water has a smaller force after being blocked. The blocked water then contacts the circuit board for flushing. The water blocking roller 92 drives the three guide rods 91 to move towards each other, and the connecting spring 921 is compressed. When the linear holes 94 rotate backward, the linear holes 94 drive the three fixing rods 95 to move away from each other. The fixing rods 95 drive the three water blocking rollers 92 to move away from each other. The gap between the three water blocking rollers 92 becomes larger. The water blocking area of the three water blocking rollers 92 for the water sprayed by the nozzle 102 is smaller, so that the water contacts the circuit board for flushing in a normal state. When the three water blocking rollers 92 are adjusted to the required water blocking position, turn off the servo motor 97. The annular disc 93 stops driving the linear holes 94 to rotate, and the water blocking roller 92 also stops moving. Then when the nozzle 102 sprays water, the water blocking roller 92 blocks part of the sprayed water, and the blocked water then flushes the circuit board. In this way, it can prevent some circuit boards from being damaged due to the inability to withstand the relatively large spraying force of the water, thus improving the safety of the circuit board flushing.

[0038] Please refer to Figure 12 As shown, the cleaning and impurity removing device for the production of new energy vehicle circuit boards further includes ball bearings 10. The ball bearings 10 are rotatably connected to the top of the perforated plate 8 at uniform intervals. When the circuit board falls onto the perforated plate 8, the ball bearings 10 can guide the circuit board.

[0039] When the clamping plate 6 releases the circuit board after cleaning and impurity removal, the circuit board falls onto the perforated plate 8 and contacts the ball bearings 10. The circuit board slides on the perforated plate 8 through the ball bearings 10. The ball bearings 10 guide the circuit board, reducing the friction between the circuit board and the perforated plate 8, so that the circuit board slides more smoothly on the perforated plate 8. In this way, excessive friction between the circuit board and the perforated plate 8 can be prevented from causing wear, thus ensuring the safety of the circuit board sliding on the perforated plate 8.
