Description

Technical Field

[0001] The present invention relates to the technical field of photosensitive dry film processing, and in particular to a device for exposure alignment and trimming of a photosensitive dry film. Background Art

[0002] In the manufacturing process of printed circuit boards, photosensitive dry film, as a key special product, plays a vital role. The edges of circuit boards often have raised edges. Such uneven raised positions can easily cause light leakage during the exposure process of the photosensitive dry film, which seriously affects the transfer accuracy of the graphics and the quality of the circuit board. Therefore, the edges of the circuit board need to be trimmed before the exposure process.

[0003] At present, in the process of photosensitive dry film processing, traditional circuit board edge trimming methods often rely on mechanical or chemical means to achieve edge removal and smoothing to facilitate the lamination of photosensitive dry film. In the actual operation of circuit board edge trimming, clamps are usually used to fix the circuit board to ensure its stability during the processing. Since the clamps need to contact the circuit board, the position of the clamps is likely to interfere with the movement trajectory of the grinding tool, making the grinding process complicated and difficult to control. In addition, the operator needs to constantly adjust the position of the grinding tool to avoid the clamps and clamp the circuit board as evenly as possible. This not only increases the difficulty of operation, but the adjustment time also reduces the trimming efficiency, which indirectly affects the exposure efficiency of the photosensitive dry film.

[0004] To this end, a photosensitive dry film exposure alignment and trimming processing device is proposed, which can adaptively allow the clamping block to avoid without affecting the trimming, is easy to operate, and improves the trimming efficiency. Summary of the invention

[0005] In order to overcome the disadvantages that the position of the clamp block easily interferes with the movement trajectory of the grinding tool due to the need for the clamp block to contact the circuit board, and the operator needs to constantly adjust the position of the grinding tool, thus affecting the finishing efficiency, the present invention provides a photosensitive dry film exposure alignment and finishing processing device which can adaptively allow the clamp block to avoid without affecting the finishing, is easy to operate, and improves the finishing efficiency.

The movement of the U-shaped rod drives the movement of the L-shaped rod, and the L-shaped rod drives the clamping block to move out of contact with the edge of the circuit board, so that the clamping block can avoid and does not affect the grinder's trimming of the edge of the circuit board. The dust suction component is installed on the box body, and is used to remove dust and debris generated during the trimming process.

[0008] According to a further description, a corrugated cover is also included which is connected between the clamping block and the return plate. The corrugated cover is sleeved on the connecting spring to block dust and debris.

[0010] Further explanation, the material transport assembly includes an electric drive roller installed at the bottom of the exposure platform, which is used to drive the trimmed circuit board to move to the left to the exposure position. The top of the exposure platform is symmetrically slidably connected with a guide frame located directly above the electric drive roller.

[0014] As a further explanation, the switching assembly also includes rubber seats fixed to the top of the limit seat at even intervals to cushion the electric lifting plate.

[0015] The beneficial effects of the present invention are:

[0016] 1. Whenever the circuit board is placed in the box, the clamp block is moved to clamp the circuit board, and the electric grinding disc can be started to trim the edge of the circuit board. The clamp block can avoid the electric grinding disc under the action of the L-shaped rod and the U-shaped rod without affecting the grinding and trimming of the electric grinding disc. When the electric grinding disc continues to move, the clamp block is reset to continue to clamp the circuit board. In this way, there is no need to manually adjust the clamping position, which is convenient to operate and improves the trimming efficiency.

[0017] 2. Whenever the electric slide rail drives the electric grinding disc to move and trim the edge of the circuit board, start the jet pump so that the air pipe blows the dust and debris generated during the trimming process to the dust suction pipe. The dust suction pipe draws the dust and debris into the jet pump and is filtered by the filter bag to prevent the dust and debris from adhering to the circuit board and affecting the fit between the photosensitive dry film and the circuit board, thereby ensuring the exposure effect of the photosensitive dry film.

[0018] 3. Under the action of the support seat, every time the trimming of both sides of the circuit board is completed, the support seat can drive the circuit board to rotate 90 degrees, so that the other two sides of the circuit board can be rotated to the trimming position for subsequent trimming. There is no need to manually rotate the circuit board to complete the trimming of the other two sides, thereby improving the trimming efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figure 6 and Figure 7 As shown, the dust collection assembly includes a dust collection pipe 10, a jet pump 11, a cover plate 12, an air blowing pipe 13 and a filter bag 131. The air blowing pipe 13 is symmetrically fixed to the top of the box body 1. The air blowing ends of the air blowing pipes 13 on the front and rear sides are respectively facing the front and rear sides of the box body 1. The middle of the front and rear sides of the box body 1 are connected with the dust collection pipe 10. The front and rear sides of the dust collection pipes 10 are respectively located on the front and rear sides of the electric lifting plate 31. The jet pump 11 is symmetrically installed on the bottom of the box body 1. The air outlet ends of the front and rear sides of the jet pumps 11 are respectively connected to the front and rear sides of the blowing pipes 13. The left end of the air pipe 13 is fixedly connected, and the air inlet ends of the front and rear jet pumps 11 are respectively connected to the air outlet ends of the front and rear dust suction pipes 10, and the sides of the front and rear jet pumps 11 that are away from each other are rotatably connected with a cover plate 12. Filter bags 131 are clamped on the inner sides of the front and rear jet pumps 11. When the jet pump 11 is started, the air blowing pipe 13 blows the dust and debris generated during the trimming process toward the dust suction pipe 10, so that the dust suction pipe 10 draws the dust and debris into the jet pump 11 and contacts with the filter bag 131 to be filtered and removed.

[0035] First, place the circuit board that needs to be exposed into the box 1 through the opening on the right side of the box 1, and make the circuit board within the clamping range of the electric clamp 91, then start the electric screw 8 to rotate forward to drive the front and rear return plates 4 to move towards each other, and the return plates 4 drive the front and rear electric grinding discs 7 to move towards each other through the electric slide rails 5 and the electric swing seat 6, and the front and rear electric grinding discs 7 are close to the edge of the circuit board, and at the same time, the return plate 4 drives the front and rear clamping blocks 141 to move towards each other through the connecting spring 143, and the front and rear clamping blocks 141 are in contact with the circuit board, thereby clamping and fixing the circuit board to prevent the circuit board from moving and affecting the accuracy of trimming, thereby ensuring the accuracy of circuit board trimming, and closing the electric screw. Rod 8, clamping block 141 and electric grinding disc 7 stop moving, then start the electric slide rail 5, cylinder 51 and electric swing seat 6 to drive the electric grinding disc 7 to move and swing, adjust the position and angle of the electric grinding disc 7, so that the electric grinding disc 7 contacts the edge of the circuit board, start the electric grinding disc 7, and then start the electric slide rail 5 to move left, drive the electric grinding disc 7 to move left through the electric swing seat 6, and the electric grinding disc 7 moves left to trim the edge of the circuit board so that the edge of the circuit board is flat. As the electric slide rail 5 continues to move to the left, the electric slide rail 5 drives the U-shaped rod 145 to move left, and the U-shaped rod 145 moves left to contact the L-shaped rod 144, and the U-shaped rod 145 drives the L-shaped rods 144 on the front and rear sides to move away from each other. The L-shaped rod 144 drives the front and rear clamping blocks 141 to move away from each other, and the connecting spring 143 and the corrugated cover 142 are compressed. The corrugated cover 142 can prevent dust and debris from falling on the connecting spring 143 and the guide rod 14, causing jamming and affecting subsequent use. The front and rear clamping blocks 141 move away from each other and disengage from the circuit board, which does not affect the electric grinding disc 7 to trim the circuit board. The remaining clamping blocks 141 continue to clamp the circuit board. When the electric grinding disc 7 continues to move to the left and drives the U-shaped rod 145 to move to the left, the U-shaped rod 145 disengages from the L-shaped rod 144. Due to the action of the connecting spring 143, the front and rear clamping blocks 141 move toward each other and reset, and the clamping blocks 141 continue to clamp the circuit board. The plate is clamped and fixed, and this is repeated. Whenever the electric grinding disc 7 moves, the clamping block 141 can avoid and not affect the grinding and finishing of the electric grinding disc 7. No manual adjustment is required, and the operation is convenient, thereby improving the finishing efficiency. At the same time, the jet pump 11 is started to discharge air into the blowing pipe 13, and the blowing pipe 13 sprays air on the finishing area of ​​the circuit board. The air blows the debris and dust generated during the finishing process of the circuit board toward the dust suction pipe 10. Since the sealing plate 92 blocks the opening of the box body 1 to prevent dust and debris from being discharged from the box body 1, the jet pump 11 evacuates the dust suction pipe 10 at the same time, so that the dust suction pipe 10 is in a negative pressure state, and the dust suction pipe 10 draws the blowing dust and debris into the jet pump 11, and the dust and debris are in contact with the filter bag 131.The filter bag 131 filters the dust and debris, and the air filtered by the dust and debris is discharged into the air pipe 13 by the jet pump 11 and sprayed out. This process is repeated to continuously remove the dust and debris generated during the trimming process to prevent the dust and debris from adhering to the circuit board and affecting the degree of adhesion between the photosensitive dry film and the circuit board, thereby ensuring the exposure effect of the photosensitive dry film. When the electric grinding disc 7 moves to the maximum left stroke, the electric slide rail 5 is started to move right, and the electric swing seat 6 drives the electric grinding disc 7 to move right and reset. The electric grinding disc 7 moves right and resets to trim the edge of the circuit board again. The electric slide rail 5 is closed. When the edges of the front and rear sides of the circuit board are trimmed, the electric screw 8 is started to reverse and drive the front and rear return plates 4 to move away from each other and reset, so that the front and rear clamping blocks 141 move away from each other and reset. The clamping block 141 releases the circuit board, and then pulls the right sealing plate 21 to swing upward and open, and takes the trimmed circuit boards on the front and rear sides out of the box body 1, so that the circuit board is rotated ninety degrees and put into the box body 1 again for trimming on the other two sides. When all four sides of the circuit board are trimmed, turn off the electric grinding disc 7 and the jet pump 11, stop blowing through the air pipe 13 and stop extracting through the dust suction pipe 10, pull the front and rear door 2 to swing open, then pull the cover plate 12 to swing open downward, take out the filter bag 131 from the jet pump 11 to process the dust and debris at the filter. After all the dust and debris are poured out, snap the filter bag 131 back into the jet pump 11, pull the cover plate 12 to swing upward and close, then pull the door 2 to swing closed, and at the same time, start the moving module 9 to drive the push rod 92 to move to the right side of the circuit board first, then the moving module 9 drives the push rod 92 to move to the left, and the push rod 92 drives the electric The road plate moves to the left through the opening on the left side of the box body 1 and contacts the electric drive roller 93 and the guide wheel 96. At this time, the circuit board is in the exposure platform 3. The electric drive roller 93 is started to reverse. The electric drive roller 93 reverses and cooperates with the guide wheel 96 to drive the trimmed circuit board to move to the left to the exposure position. Due to the effect of the buffer spring 95, the guide wheel 96 can closely contact the circuit board for guidance. The electric drive roller 93 is closed and the exposure platform 3 is started to expose the photosensitive dry film on the trimmed circuit board. In this way, the exposure effect of the photosensitive dry film of the circuit board is better. When the exposure process of the photosensitive dry film of the circuit board is completed, the circuit board is taken out of the exposure platform 3.

On the vertical rod 1521, a support seat 151 is rotatably connected in the middle of the limit seat 152, and the support seat 151 rotatably passes through the middle of the electric lifting plate 31.

Four rubber seats 156 are fixedly connected to the top of the limit seat 152 at uniform intervals along the circumferential direction. When the electric lifting plate 31 moves downward and contacts the rubber seat 156, the rubber seat 156 can buffer the electric lifting plate 31 to prevent the electric lifting plate 31 from being directly and violently contacting the limit seat 152 and causing damage.

[0037] When the circuit board moves to the left into the box body 1, the electric clamp 91 releases the circuit board, and the circuit board falls downward onto the electric lifting plate 31 and contacts the guide seat 15. Then the electric clamp 91 clamps and fixes the circuit board, and the edges of the front and rear sides of the circuit board can be trimmed. When the edges of the front and rear sides of the circuit board are trimmed, the electric clamp 91 releases the circuit board, and the electric lifting plate 31 is started to move downward to drive the guide seat 15 to move downward. The guide seat 15 drives the circuit board to move downward. When the circuit board moves downward and contacts the support seat 151, the circuit board stops moving downward, and the guide seat 15 continues to move downward and disengages from the circuit board. When the plate 31 moves downward and contacts the rubber seat 156, the rubber seat 156 cushions the electric lifting plate 31 to prevent the electric lifting plate 31 from violently contacting the limit seat 152 and causing damage. As the electric lifting plate 31 continues to move downward, the electric lifting plate 31 drives the limit seat 152 to move downward through the rubber seat 156, the support spring 153 is compressed, the limit seat 152 moves downward and drives the support seat 151 to move downward, the support seat 151 drives the inner spline cylinder 1551 to move downward, the inner spline cylinder 1551 moves downward and slides on the spline shaft 155, and the support seat 151 moves downward synchronously with the electric lifting plate 31, and the support seat 153 is compressed. 51 moves downward, driving the circuit board downward. The circuit board moves downward and is under the electric clamp 91. The electric lifting plate 31 is turned off. The electric lifting plate 31 stops moving downward through the rubber seat 156 to drive the limit seat 152. The limit seat 152 stops driving the support seat 151 downward, and the circuit board also stops moving downward. The drive motor 154 is started to drive the spline shaft 155 to rotate ninety degrees. The spline shaft 155 drives the inner spline cylinder 1551 to rotate. The inner spline cylinder 1551 drives the support seat 151 to rotate. The rotation of the support seat 151 drives the circuit board to rotate ninety degrees. The drive motor 154 is turned off. The electric lifting plate 31 is started to move upward to drive the guide seat 15 moves upward, and as the electric lifting plate 31 continues to move upward, the electric lifting plate 31 stops applying pressure to the rubber seat 156. Due to the action of the support spring 153, the limit seat 152 moves upward to drive the support seat 151 to move upward, and the support seat 151 drives the inner spline cylinder 1551 to move upward and reset. The support seat 151 moves upward to drive the circuit board to move upward. When the support seat 151 moves upward and resets, the support seat 151 stops moving upward, and then the guide seat 15 continues to move upward to contact the circuit board. The guide seat 15 drives the circuit board to move upward and reset, and the circuit board can continue to be clamped and fixed, and the untrimmed two sides of the circuit board can be trimmed. In this way, there is no need to manually rotate the circuit board to complete the trimming of the other two sides, thereby improving the trimming efficiency.
