Description

Technical Field

[0001] The invention relates to the technical field of cleaning circuit board electroplating, in particular to a workpiece surface cleaning device before electroplating. Background Art

[0002] Circuit board is one of the common electroplating workpieces. The electroplating of circuit board can be divided into single-sided electroplating and double-sided electroplating. Among them, single-sided electroplating of circuit board is more widely used. During the manufacturing process of circuit board, dust or other impurities may remain on the surface. If they are not cleaned before electroplating, these impurities will seriously affect the quality of circuit board electroplating. Therefore, the surface to be plated needs to be cleaned before single-sided electroplating of the circuit board.

[0003] At present, the cleaning method of the single-sided circuit board before electroplating mainly adopts the large-scale circuit board conveying and blowing cleaning method for cleaning, but this cleaning method has the following shortcomings: 1. When the circuit board is cleaned by the method of conveying and cleaning at the same time, the cleaning brush contacts the surface of the circuit board, which will produce resistance to the movement of the circuit board. The circuit board is placed flat on the conveying mechanism, and the resistance generated by the cleaning brush will affect the conveying of the circuit board by the conveying mechanism, causing the circuit board to slip and stagnate, affecting the subsequent cleaning of the circuit board; 2. The cleaning brush needs an independent power source to drive during the operation, which increases the cost of the cleaning device. In addition, the distance between the cleaning brush and the conveying mechanism is small and fixed. When the cleaning brush needs to be replaced and cleaned, the small and fixed height is not conducive to the replacement of the cleaning brush, affecting the efficiency of circuit board production and processing; 3. In the process of cleaning the circuit board, the air pump and exhaust fan used to clean the dust are always in a working state. Since the circuit boards are transferred to the cleaning device one by one for cleaning, there is a certain time interval between different circuit boards. The air pump and exhaust fan working during the interval will cause energy waste and increase the production cost of the circuit board. Summary of the invention

When the lifting and adjusting assembly drives the cleaning roller to move up and down, the elastic telescopic rod 2 can be telescopically deformed to adjust the tension of the belt in the transmission tensioning assembly, which is beneficial for the conveying mechanism to drive the cleaning roller that moves up and down to different heights.

[0020] 4. The present invention is provided with a dust collection mechanism. When the circuit board moves to the second lifting and adjusting component, the circuit board can drive the second lifting and adjusting component to operate and drive the dust collection head to move downward close to the circuit board. At the same time, the outward rotating driving part of the second lifting and adjusting component can press the trigger switch, thereby starting the vacuum cleaner, so that the dust collection head can vacuum the circuit board, thereby improving the cleaning effect of the circuit board. When the circuit board moves out of the second lifting and adjusting component, the driving part in the second lifting and adjusting component no longer triggers the switch, and the vacuum cleaner is automatically turned off, which is more energy-saving and environmentally friendly and does not require additional control.

[0035] See also Figure 3 , Figure 5 and Figure 8 The lifting and lowering adjustment component 43 includes a driving part 431 and a lifting part 432 installed on the top of the wing plate 11, and the driving part 431 and the lifting part 432 are connected through a gear set.

[0037] The conveyor roller 21 is driven to rotate by the driving motor 23, and the conveyor belt 22 is driven to rotate by the conveyor roller 21. The top of the conveyor belt 22 is slightly higher than the top of the wing plate 11. The circuit board 6 is placed on the conveyor belt 22, and the conveyor belt 22 is used to transport the circuit board 6 to the right to the cleaning mechanism 4 and the dust collection mechanism 5, so as to continuously clean the circuit board 6.

[0038] See also Figure 2 and Figure 3 The guide assembly 31 includes two first transmission rods 311 rotatably mounted in the wing plate 11, and a guide belt 312 is transmission-connected between the outer portions of the top ends of the two first transmission rods 311. The front and rear guide assemblies 31 form an eight-shaped shape, and the opening at the left end is larger than the opening at the right end.

[0039] The guide belt 312 is driven to rotate by the first transmission rod 311. When the circuit board 6 moves to the guide assembly 31, the two guide assemblies 31 forming an eight-shaped shape can guide and align the circuit board 6, which is beneficial for guiding and conveying the circuit board 6 to the clamping assembly 32 and avoiding the circuit board 6 from being skewed.

[0040] See also Figure 2 , Figure 3 and Figure 4 The clamping and conveying assembly 32 includes a second transmission rod 321 rotatably installed inside the wing plate 11. The top end of the second transmission rod 321 extends to the top of the wing plate 11 and is fixedly sleeved with a rubber wheel 322.

Two adjacent second transmission rods 321 are connected by belt transmission. The leftmost second transmission rod 321 is connected to the rightmost first transmission rod 311 through a belt.

[0041] The second transmission rod 321 is driven to rotate by the conveying roller 21, and then the second transmission rod 321 drives the rubber wheel 322 to rotate. The rubber wheel 322 can be clamped on the front and rear sides of the circuit board 6 and drive the circuit board 6 to move rightward, which can increase the driving force for the circuit board 6 to move rightward and prevent the circuit board 6 from slipping or stopping on the conveying mechanism 2.

[0042] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The mounting assembly 41 includes an elastic telescopic rod 411 fixedly mounted on the lower side of the top wall of the gantry 12, a fixed shaft sleeve 412 is rotatably mounted on the bottom of the elastic telescopic rod 411, a mounting hole 413 is provided on the side of the fixed shaft sleeve 412 close to the conveying mechanism 2, a sliding block 414 is slidably mounted on the left side of the fixed shaft sleeve 412, a spring member 415 is fixedly connected between the side of the sliding block 414 close to the elastic telescopic rod 411 and the opposite side of the fixed shaft sleeve 412, and a roller shaft 421 is fixedly connected to the front and rear ends of the cleaning roller 42, and the roller shaft 421 matches the mounting hole 413.

[0043] When the cleaning roller 42 needs to be replaced, slide the sliding block 414 in the direction away from the cleaning roller 42, and then take out the roller shaft 421 from the inside of the mounting hole 413 to complete the disassembly of the cleaning roller 42, and then insert the roller shafts 421 at both ends of the new cleaning roller 42 into the mounting holes 413 inside the corresponding fixed sleeve 412, and then release the sliding block 414, and push the mounting hole 413 in the direction close to the cleaning roller 42 by means of the spring member 415 to block the roller shaft 421 to prevent the roller shaft 421 from loosening, so that the cleaning roller 42 can be easily and quickly disassembled and replaced.

[0044] See also Figure 2 , Figure 3 , Figure 5 and Figure 8The driving part 431 includes a support frame 4311 rotatably mounted on the top of the wing plate 11 through a rotating rod, and rollers 4312 are rotatably mounted on both ends of the support frame 4311. A movable belt 4313 is transmission-connected between the outsides of the rollers 4312. The bottom of the rotating rod extends to the bottom of the wing plate 11 and is coaxially connected to a transmission gear 4315.

[0045] See also Figure 1 , Figure 3 , Figure 5 and Figure 8 The lifting part 432 includes a lifting guide rail 4321 fixedly installed on the top of the wing plate 11, a lead screw 4322 is rotatably installed inside the lifting guide rail 4321, a slider 4323 is threadedly sleeved on the outside of the lead screw 4322, and the slider 4323 is slidably installed inside the lifting guide rail 4321, and a linkage plate 4324 is fixedly connected to the side of the slider 4323 close to the mounting assembly 41, and the linkage plate 4324 is rotatably sleeved on the outside of the fixed shaft sleeve 412. The bottom end of the lead screw 4322 extends to the bottom of the wing plate 11 and is coaxially fixedly connected to a transmission gear 2 4325, and the transmission gear 2 4325 is meshed with the transmission gear 1 4315.

[0046] In the initial state, the driving part 431 is tilted to the side of the rubber wheel 322 close to the conveying mechanism 2. When the circuit board 6 moves to the driving part 431, the circuit board 6 pushes the support frame 4311 to rotate in the direction away from the conveying mechanism 2. The support frame 4311 drives the lead screw 4322 to rotate after being driven by the transmission gear 1 4315 and the transmission gear 2 4325, so that the slider 4323 moves downward along the lifting guide rail 4321, and then drives the cleaning roller 42 to move downward, so that the cleaning roller 42 can be attached to the top of the circuit board 6 for cleaning.

[0047] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The transmission tensioning assembly 44 includes a transmission shaft 441 rotatably mounted on the inside of the side wall of the gantry 12, and the end of the transmission shaft 441 away from the conveying mechanism 2 extends to the outside of the gantry 12 and is connected to one of the conveying rollers 21 through a belt transmission. The inside of the side wall of the gantry 12 is fixedly connected with a fixed rod 442 located between the transmission shaft 441 and the fixed shaft sleeve 412, and the side of the fixed rod 442 away from the gantry 12 is fixedly connected with an elastic telescopic rod 443, and the end of the elastic telescopic rod 443 away from the fixed rod 442 is rotatably mounted with a tensioning shaft 444, and the transmission shaft 441, the fixed shaft sleeve 412 and the outside of the tensioning shaft 444 are connected through a belt transmission.

[0048] The conveying roller 21 drives the transmission shaft 441 to rotate through the belt, and then the transmission shaft 441 drives the fixed sleeve 412 and the cleaning roller 42 to rotate through the belt, so that the cleaning roller 42 cleans the circuit board 6. When the fixed sleeve 412 rises and falls, the elastic telescopic rod 443 can be extended and retracted with the rise and fall of the fixed sleeve 412, thereby adjusting the tension of the belt to prevent the belt from loosening.

[0049] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 The dust collecting mechanism 5 includes an elastic telescopic rod three 51 fixedly mounted on the lower side of the top wall of the gantry 12 and symmetrically distributed about the front and rear of the conveying platform 1. A dust collecting component 52 is installed between the two elastic telescopic rods three 51. A lifting and adjusting component two 53 for driving the dust collecting component 52 to move up and down is installed on the top of the wing plate 11. The lifting and adjusting component two 53 has the same structure as the lifting and adjusting component one 43. A switch 54 for controlling the opening and closing of the lifting and adjusting component two 53 is also installed on the top of the wing plate 11. The switch 54 is located on the side of the driving part 431 in the lifting and adjusting component two 53 away from the conveying mechanism 2. When the driving part 431 in the lifting and adjusting component two 53 rotates to be flush with the rubber wheel 322, the driving part 431 in the lifting and adjusting component two 53 presses the trigger switch 54.

[0050] See also Figure 1 , Figure 2 , Figure 5 and Fig. 9 The dust collection component 52 includes a dust collection head 521 fixedly installed between the bottom ends of the elastic telescopic rods 51, a dust collector 522 is installed on the top of the gantry 12, the dust collection head 521 and the dust collector 522 are connected by a bellows, and the lifting and adjusting component 2 53 drives the dust collection head 521 to move up and down.

[0051] When used specifically, step one: drive the conveying roller 21 to rotate through the driving motor 23, and then the conveying roller 21 drives the conveying belt 22 to operate, and then place the circuit board 6 on the conveying belt 22, and convey the circuit board 6 to the right through the conveying belt 22.

[0052] Step 2: The conveying roller 21 drives the second transmission rod 321 to rotate through the belt, and the second transmission rods 321 transmit transmission to each other through the belt, and then the second transmission rod 321 drives the first transmission rod 311 to rotate through the belt, and the first transmission rod 311 drives the guide belt 312 to rotate. When the right end of the circuit board 6 is conveyed to the guide assembly 31, the guide belt 312 is used to guide and center the circuit board 6, and the circuit board 6 is conveyed between the front and rear rubber wheels 322. The rubber wheels 322 are clamped on the front and rear sides of the circuit board 6 and convey the circuit board 6 to the right.

[0053] Step three: the conveying roller 21 rotates the transmission shaft 441 through the belt, and then the transmission shaft 441 rotates the fixed sleeve 412 and the cleaning roller 42 through the belt. When the circuit board 6 has not moved to the lifting and adjusting component 43, the end of the driving part 431 away from the rotating rod is pushed by the spring part 4314 to be close to the conveying mechanism 2. When the circuit board 6 moves to the lifting and adjusting component 43, the driving part 431 is pushed by the circuit board 6 to rotate in the direction away from the conveying mechanism 2. At this time, the support frame 4311 drives the lead screw 4322 to rotate through the transmission gear 1 4315 and the transmission gear 2 4325, so that the slider 4323 moves downward along the lead screw 4322, and the linkage plate 4324 drives the cleaning roller 42 to move down to the top of the circuit board 6 for cleaning.

[0054] Step 4: Similarly, when the circuit board 6 moves to the lifting and adjusting component 2 53, the lifting and adjusting component 2 53 can drive the dust collector head 521 to move downward to a position close to the top of the circuit board 6, and the support frame 4311 in the lifting and adjusting component 2 53 can press the trigger switch 54 when it rotates to be flush with the rubber wheel 322, so that the dust collector 522 is turned on, so that the dust collector head 521 sucks the dust on the top of the circuit board 6 into the dust collector 522.

[0055] Step 5: When the cleaning roller 42 needs to be replaced, push the sliding block 414 in the direction away from the cleaning roller 42, then remove the roller shaft 421 from the inside of the fixed sleeve 412, and then replace the new cleaning roller 42, insert the roller shafts 421 at both ends of the newly replaced cleaning roller 42 into the inside of the mounting hole 413, and then release the sliding block 414, and push the sliding block 414 to move towards the cleaning roller 42 through the spring member 415 and block the roller shaft 421 to prevent the roller shaft 421 from detaching.
