The push plate 142 passes through the electric conveying roller 2 and is located in the airbag 14. 1, when the push plate 142 moves upward, the push plate 142 can drive the ceramic-based circuit board to move upward. A transmission assembly is provided between the push plate 142 and the electric pressing plate 14. When the transmission assembly is in operation, the transmission assembly can drive the push plate 142 to move. The transmission assembly includes an L-shaped rack I 143, a spur gear 144 and an L-shaped rack II 145. The left front side of the electric pressing plate 14 is fixedly connected to the L-shaped rack I 143, and the right front lower side of the leftmost partition plate 4 is rotatably connected to the spur gear 144.

The front side of the push plate 142 is fixedly connected to the L-shaped rack II 145, and the L-shaped rack II 145 is engaged with the spur gear 144.

[0033] See also Figure 4 and Figure 6 As shown, the extrusion assembly includes a drainage frame 15 and a squeezing roller 151. The drainage frame 15 is fixedly connected to the left side of the bottom of the box body 1. The drainage frame 15 is located directly below the tensioning roller 12. The squeezing roller 151 is rotatably connected between the upper left and right sides of the drainage frame 15. The squeezing roller 151 is in contact with the water-absorbing belt 9. When the squeezing roller 151 rotates, the squeezing roller 151 can squeeze out the etching liquid in the water-absorbing belt 9.

[0034] Initially, the jet head 6 is externally connected to an air pump and the electric liquid spray head 5 is externally connected to a machine filled with etching liquid. First, the electric conveyor roller 2 is started to intermittently reverse, and then the ceramic-based circuit board is placed on the electric conveyor roller 2 from the right. The intermittent reversal of the electric conveyor roller 2 drives the ceramic-based circuit board to move intermittently to the left. When the ceramic-based circuit board moves to the left to just below the electric liquid spray head 5, the electric liquid spray head 5 is started. The electric liquid spray head 5 sprays the etching liquid on the ceramic-based circuit board below, and the etching liquid etches the ceramic-based circuit board. The etching liquid after etching the ceramic-based circuit board falls into the collection frame 3, and the etching liquid is discharged through the collection frame 3. When the etching of the ceramic-based circuit board is completed, the ceramic-based circuit board continues to move to the left intermittently. When the etched ceramic-based circuit board moves to the left to the push plate When the electric conveyor roller 2 is between 142 and the water absorption belt 9, the electric conveyor roller 2 stops reversing. At this time, the next ceramic-based circuit board is directly under the electric liquid spray head 5 for etching, and the electric pressing plate 14 is started at the same time. The electric pressing plate 14 moves downward, driving the air bag 141 to move downward. The air bag 141 moves downward to push the water absorption belt 9 to move downward. The electric pressing plate 14 moves downward and also drives the L-shaped rack I 143 to move downward. The L-shaped rack I 143 moves downward and drives the spur gear 144 to rotate forward. The spur gear 144 rotates forward and drives the L-shaped rack II 145 to move upward. The L-shaped rack II 145 moves upward and drives the push plate 142 to move upward. The push plate 142 moves upward and drives the movable rod 11 to move upward through the n-shaped rod 1411. The connecting spring 13 is compressed and the movable rod 11 The upward movement drives the tensioning roller 12 to move upward. At the same time, the upward movement of the push plate 142 also drives the ceramic-based circuit board to move upward. The ceramic-based circuit board moves upward and contacts the water-absorbing belt 9. The airbag 141 moves downward to press the water-absorbing belt 9 on the ceramic-based circuit board. Due to the action of the airbag 141, the water-absorbing belt 9 can be closely attached to the etching position of the ceramic-based circuit board. The electric pressing plate 14 is closed. At this time, the water-absorbing belt 9 can absorb and remove the etching machine attached to the ceramic-based circuit board. Then the electric pressing plate 14 drives the airbag 141 to move upward and reset. The airbag 141 moves upward and stops applying pressure to the water-absorbing belt 9. The electric pressing plate 14 also drives the push plate 142 to move downward through the L-shaped rack I 143, the spur gear 144 and the L-shaped rack II 145. The push plate 142 is reset, and the ceramic-based circuit board is reset. The ceramic-based circuit board continues to be on the electric conveyor roller 2. The push plate 142 also drives the movable rod 11 to move downward and reset through the n-shaped rod 1411. The movable rod 11 is reset to reset the connecting spring 13. The movable rod 11 also drives the tensioning roller 12 to move downward and reset. The tensioning roller 12 is reset to tighten the water-absorbing belt 9. At this time, the drive motor 81 is started to rotate forward to drive the belt roller 8 at the lower front side to rotate forward. The belt roller 8 at the lower front side drives the water-absorbing belt 9 to rotate forward through the remaining three belt rollers 8. When the unused position of the water-absorbing belt 9 rotates forward to just below the airbag 141, the drive motor 81 is turned off, and the belt roller 8 stops driving the water-absorbing belt 9 to rotate forward. Then when the electric conveyor roller 2 reverses again,The electric conveyor roller 2 drives the ceramic-based circuit board for cleaning the etching liquid and the ceramic-based circuit board after etching to move to the left. The ceramic-based circuit board after etching moves to the left between the push plate 142 and the water absorption belt 9 to clean the etching liquid. The ceramic-based circuit board for cleaning the etching liquid moves to the left and is directly under the nozzle head 6. The external air pump is started, and the air pump discharges air into the nozzle head 6. The nozzle head 6 sprays air to dry the ceramic-based circuit board directly below, so that the ceramic-based circuit board is in a dry state. Since the etching liquid attached to the ceramic-based circuit board is absorbed and removed, the ceramic-based circuit board is more convenient to dry, thereby improving the overall work efficiency. When the electric conveyor roller 2 continues to reverse, the dried ceramic-based circuit board moves to the left outside the box 1, and the operator can collect the ceramic-based circuit board for subsequent processing. This is repeated to continuously clean the ceramic-based circuit board. Etching, removing etching liquid and drying process. When the water absorption belt 9 rotates forward so that the position after absorbing water rotates forward to contact with the squeezing roller 151, under the action of the connecting spring 13, the squeezing roller 151 and the tensioning roller 12 can squeeze out the etching liquid in the water absorption belt 9 to prevent the water absorption belt 9 from absorbing a large amount of etching liquid and affecting the subsequent use effect, thereby improving the long-term use effect of the water absorption belt 9. The squeezed etching liquid falls into the drainage frame 15 through the squeezing roller 151. The drainage frame 15 discharges the etching liquid for collection and treatment. The water absorption belt 9 that has squeezed out the etching liquid continues to absorb and remove the etching liquid on the subsequent ceramic-based circuit boards. When all ceramic-based circuit boards are etched, the external air pump is turned off, the air jet head 6 stops spraying air, and the electric liquid spray head 5 is turned off at the same time. The etching liquid stops spraying, and the etched ceramic-based circuit boards can be processed subsequently.

[0035] See also Figure 7As shown, the ceramic-based circuit board etching device also includes a correction component installed on the box body 1, the correction component includes a guide rod 16, a U-shaped movable plate 161, a U-shaped correction plate 162, a buffer spring 163, a bidirectional screw 164 and a stepping motor 165, and a guide rod 16 is fixedly connected between the right sides of the front and rear sides of the box body 1. The guide rod 16 is symmetrically and slidably mounted with a U-shaped movable plate 161 on the front and rear sides, and the guide rod 16 is slidably mounted with a U-shaped correction plate 162 on the front and rear sides. The U-shaped correction plate 162 is located above the electric conveying roller 2. When the U-shaped correction plate 162 moves and contacts the ceramic-based circuit board, the U-shaped correction plate 162 can correct the ceramic-based circuit board and position it so that the ceramic The porcelain-based circuit board is in a corrected position, and a buffer spring 163 is connected between the sides of the front and rear U-shaped correcting plates 162 that are away from each other and the sides of the front and rear U-shaped movable plates 161 that are close to each other. The buffer spring 163 is sleeved on the guide rod 16, and a bidirectional screw 164 is rotatably connected between the right sides of the front and rear sides of the box body 1. The threads on the front and rear sides of the bidirectional screw 164 are opposite, and the bidirectional screw 164 is threadedly connected to the front and rear U-shaped movable plates 161. The bidirectional screw 164 slides through the front and rear U-shaped correcting plates 162. A stepper motor 165 is installed on the right side of the outer front side of the box body 1, and the output shaft end of the stepper motor 165 is fixedly connected to the front end of the bidirectional screw 164.

[0036] See also Figures 8-10 As shown, the ceramic-based circuit board etching device also includes a cleaning component, which includes a rotating shaft 17, a brush roller 171, a guide gear 172, an inverted V-shaped plate 173 and a collecting component. The rotating shaft 17 is symmetrically rotated between the lower left and right sides of the front shell 7. The right side of the front rotating shaft 17 is connected to the output shaft of the drive motor 81 through a synchronous belt assembly. Brush rollers 171 are fixedly mounted on the front and rear rotating shafts 17. The front and rear brush rollers 171 are in contact with the water absorption belt 9. When the brush rollers 171 rotate, the brush rollers 171 can remove impurities attached to the water absorption belt 9. The right sides of the front and rear rotating shafts 17 are The fixed sleeve is equipped with a guide gear 172, and the guide gears 172 on the front and rear sides are meshed. An inverted V-shaped plate 173 is fixedly connected to the lower part of the outer front side of the box body 1, and the inverted V-shaped plate 173 is located below the rear brush roller 171. The inverted V-shaped plate 173 can guide impurities so that the impurities are discharged from the front shell 7. A collecting component is provided on the front side of the box body 1, and the collecting component can collect fallen impurities; the collecting component includes a support frame 18 and a material receiving frame 19. The lower part of the outer front side of the box body 1 is fixedly connected to the support frame 18, and the support frame 18 is located below the front shell 7. A material receiving frame 19 is placed on the support frame 18, and the material receiving frame 19 can collect impurities.

[0037] When the ceramic-based circuit board moves to the left between the front and rear U-shaped correcting plates 162, the stepper motor 165 is started, and the stepper motor 165 drives the bidirectional screw 164 to rotate forward. The bidirectional screw 164 rotates forward to drive the front and rear U-shaped movable plates 161 to move toward each other. The U-shaped movable plates 161 drive the front and rear U-shaped correcting plates 162 to move toward each other through the buffer spring 163. The U-shaped correcting plates 162 move toward each other and contact the ceramic-based circuit board. The front and rear U-shaped correcting plates 162 correct the ceramic-based circuit board and position it, so that the ceramic-based circuit board is in a swinging position. The U-shaped correcting plate 162 is positioned in the correct position for subsequent etching, cleaning of the etching liquid, and drying. Due to the action of the buffer spring 163, the U-shaped correcting plate 162 can be in close contact with the ceramic-based circuit board for correcting positioning. After the ceramic-based circuit board is corrected and positioned, the stepping motor 165 is started to drive the bidirectional screw 164 to reverse. The bidirectional screw 164 reverses and drives the front and rear U-shaped movable plates 161 to move away from each other and reset. The U-shaped movable plate 161 drives the front and rear U-shaped correcting plates 162 to move away from each other and reset through the buffer spring 163. The U-shaped correcting plates 162 are reset and disengaged from the ceramic-based circuit board. In this way, the ceramic-based circuit board can be prevented from being in a skewed state and affecting the removal of the etching liquid, thereby ensuring that the ceramic-based circuit board can be fully cleaned of the etching liquid.

[0038] When the driving motor 81 rotates forward and drives the water absorption belt 9 to rotate forward through the belt roller 8, the driving motor 81 rotates forward and also drives the front shaft 17 to rotate forward through the synchronous belt assembly. The front shaft 17 rotates forward and drives the front brush roller 171 to rotate forward. The front shaft 17 also drives the front guide gear 172 to rotate forward. The front guide gear 172 rotates forward and drives the rear guide gear 172 to rotate reversely. The rear guide gear 172 reverses and drives the rear shaft 17 to reverse. The reverse rotation of the rear shaft 17 drives the rear brush roller 171 to reverse. The reverse rotation of the rear brush roller 171 and the forward rotation of the front brush roller 171 remove impurities attached to the water absorption belt 9. The impurities removed by the rear brush roller 171 fall downward onto the inverted V-shaped plate 173. The inverted V-shaped plate 17 3 falls into the front shell 7, and the impurities removed by the front brush roller 171 fall directly into the front shell 7. The front shell 7 discharges the impurities into the receiving frame 19, which collects and processes the impurities. When the drive motor 81 is turned off, the drive motor 81 stops driving the water absorption belt 9 to rotate forward through the belt roller 8, and the drive motor 81 also stops driving the front shaft 17 to rotate forward. The front shaft 17 stops driving the front brush roller 171 to rotate forward, and the rear shaft 17 also stops driving the rear brush roller 171 to rotate reversely. The operator can remove the receiving frame 19 from the support frame 18 and pour out all the impurities in the receiving frame 19 for processing. After all the impurities are poured out, the receiving frame 19 is put back into the support frame 18. In this way, a large amount of impurities can be prevented from being attached to the water absorption belt 9 and affecting the subsequent absorption of the etching liquid, thereby further improving the effect of the subsequent use of the water absorption belt 9.

[0039] See also Figure 11 As shown, the ceramic-based circuit board etching device also includes a guide roller 20. The lower parts of the front and rear sides of the box body 1 are rotatably connected with the guide roller 20. The guide roller 20 is in contact with the inner side of the water-absorbing belt 9. The guide roller 20 can guide the water-absorbing belt 9 to prevent the water-absorbing belt 9 from rubbing against the box body 1 and causing wear.

[0040] When the water absorption belt 9 rotates forward, the water absorption belt 9 drives the guide roller 20 to rotate, and the guide roller 20 guides the water absorption belt 9. In this way, the water absorption belt 9 is prevented from contacting with the box body 1 and causing wear, thereby ensuring the safety of the use of the water absorption belt 9.
