Adjustable carrier plate cleaning device

Abstract

This utility model discloses an adjustable carrier board cleaning device, including a main frame and a cover, as well as a first filter screen and a second filter screen. The cover is fixedly installed at the rotating end of the hinge, and the second filter screen is fixedly connected to the surface of the cover. The first filter screen is slidably connected to the bottom of the main frame, and multiple micro suction cups for adsorbing and fixing PCB boards are evenly distributed on the upper end of the first filter screen. This adjustable carrier board cleaning device provides a transportation platform for transporting PCB boards. This avoids the problem of PCB boards easily falling out of the gap between the tube rollers and being unable to pass through due to difficulty in pushing open the water baffles, regardless of the size of the PCB boards being transported. Furthermore, after the cover is closed, the pressure strip will simultaneously squeeze the PCB boards. After the PCB boards are subjected to the squeezing force, the micro suction cups will firmly adsorb all the PCB boards at the same time. This prevents the PCB boards from colliding with each other or with the inner wall of the main frame during transportation, thus preventing scratches on the surface of the PCB boards.

Description

Technical Field

[0001] This utility model relates to the field of PCB board cleaning technology, and in particular to an adjustable carrier board cleaning device. Background Technology

[0002] In the PCB manufacturing process, large PNL boards (multiple sets are combined into one large board for high production efficiency) need to be converted into smaller sets of the size required by the customer. Therefore, routing and V-cut processes are required to cut the boards. However, dust is generated during the cutting process, so cleaning is necessary. If the dust is not cleaned properly, it will affect the soldering of the solder joints on the PCB. If there is dust on the board surface, there is a risk of insufficient solder or short circuits after surface mount reflow soldering.

[0003] Due to the limitations of the tube roller spacing and pressure roller design in the cleaning machine, there are restrictions on the length, width, and thickness of the PCB board. If the PCB board is too small, it is easy to fall out of the tube roller gap during transportation. If the PCB board is too thin, it is easy to get stuck at the water baffle of the cleaning machine. The water baffle is used to prevent cleaning water from being discharged from the outlet. The PCB board needs to be pushed open during the movement. The thinner PCB board has a smaller contact area with the water baffle, making it difficult to push open the water baffle and causing it to be unable to pass through. Therefore, a cleaning carrier board device is needed to assist the PCB board, increase its applicability, and avoid the above problems. Utility Model Content

[0004] To overcome the limitations on the length, width, and thickness of PCB boards due to the spacing between the tube rollers and the pressure rollers of the cleaning machine, which makes it easy for PCB boards to fall out of the gaps between the tube rollers during transportation and make it difficult to push open the water-blocking rollers, thus preventing them from passing through.

[0005] The technical solution of this utility model is as follows: an adjustable carrier board cleaning device, including a main frame and a cover, and also including a first filter screen and a second filter screen. A hinge is fixedly installed on one side of the upper end of the main frame, and the cover is fixedly installed on the rotating end of the hinge. The second filter screen is fixedly connected to the surface of the cover. The first filter screen is slidably connected to the bottom of the main frame. Multiple micro suction cups for adsorbing and fixing PCB boards are evenly distributed on the upper end of the first filter screen.

[0006] Preferably, a bottom baffle is fixedly connected to the four corners of the bottom of the main frame, and a guide shaft is fixedly connected to the upper end of the bottom baffle. A spring is sleeved on the surface of the guide shaft.

[0007] Preferably, sliders are fixedly connected at the four corners of the filter screen, the sliders are slidably connected to the guide shaft, and the springs are connected to the bottom baffle and the sliders.

[0008] Preferably, an adsorption magnet is fixedly connected to the surface of the bottom baffle. The adsorption magnet is used to adsorb and fix the filter screen. Pressure strips are evenly distributed at the lower end of the filter screen. The pressure strips are used to press down and move the filter screen.

[0009] Preferably, when the filter screen and the adsorption magnet are fixed together, the upper end of the PCB board does not come into contact with the pressure strip.

[0010] Preferably, one side of the cap is provided with an adsorption magnet, which is adsorbed onto the side of the main frame, and the surface of the cap is provided with a built-in handle.

[0011] Preferably, the lower end of the main frame is provided with an anti-slip pad, and the surface of the anti-slip pad is evenly distributed with drainage grooves.

[0012] The beneficial effects of this utility model are:

[0013] 1. This adjustable carrier board cleaning device provides a transportation platform for PCB board transportation. This avoids problems such as PCB boards falling out of the gap between the tube rollers and being unable to pass through due to difficulty in pushing open the water baffles, regardless of the size of the PCB boards being transported. After the cover is closed, the pressure bar will squeeze the PCB boards at the same time. After the PCB boards are squeezed, the micro suction cups will firmly adhere to all the PCB boards at the same time. This prevents the PCB boards from colliding with each other and with the inner wall of the main frame during transportation, which would cause scratches on the surface of the PCB boards.

[0014] 2. After the filter screen is pressed down, the distance between the filter screen and the adsorption magnet decreases, and the attraction increases, thereby overcoming the spring force and causing the PCB board to detach from the pressure strip. This ensures the cleaning effect and prevents the contact area between the pressure strip and the PCB board from being missed. After cleaning, the cover is opened, and the worker holds the filter screen and pulls it upwards, reducing the attraction between the filter screen and the adsorption magnet to a level insufficient to overcome the spring force. This completes the reset, ensuring that the PCB board can be smoothly pressed and adsorbed by the micro suction cup during the next cleaning. The operation is simple and convenient.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5 This utility model provides an embodiment of an adjustable carrier board cleaning device, including a main frame 1 and a cover 2, as well as a first filter screen 3 and a second filter screen 5. A hinge 4 is fixedly installed on one side of the upper end of the main frame 1, and the cover 2 is fixedly installed on the rotating end of the hinge 4. The second filter screen 5 is fixedly connected to the surface of the cover 2. The first filter screen 3 is slidably connected to the bottom of the main frame 1. Multiple micro suction cups 10 for adsorbing and fixing PCB boards are evenly distributed on the upper end of the first filter screen 3. This adjustable carrier board cleaning device provides a transportation platform for transporting PCB boards. In this way, regardless of the type and size of PCB boards being transported, it can avoid the problem of PCB boards easily falling out of the gap between the tube wheels or being unable to pass through due to difficulty in pushing open the water baffle. Furthermore, after the cover 2 is closed, the micro suction cups 10 will firmly adsorb all the PCB boards at the same time, thus preventing the PCB boards from colliding with each other or with the inner wall of the main frame 1 during transportation, which would cause scratches on the surface of the PCB boards.

[0023] Please see Figure 3 - Figure 5In this embodiment, multiple miniature suction cups 10 for adsorbing and fixing the PCB board are evenly distributed at the upper end. A bottom baffle 7 is fixedly connected to the four corners of the bottom end of the main frame 1. A guide shaft 8 is fixedly connected to the upper end of the bottom baffle 7. A spring 9 is sleeved on the surface of the guide shaft 8. A slider 11 is fixedly connected to the four corners of the filter screen 3. The slider 11 is slidably connected to the guide shaft 8. A magnetic magnet 12 is fixedly connected to the surface of the bottom baffle 7 between the spring 9 and the bottom baffle 7 and the slider 11. The magnetic magnet 12 is used to adsorb and fix the filter screen 3. Pressure strips 13 are evenly distributed at the lower end of the filter screen 5. The pressure strips 13 are used for… When the filter screen 3 is pressed down and fixed to the adsorption magnet 12, the upper end of the PCB board does not contact the pressure strip 13. Adsorption magnet 14 is located on one side of the cover 2, and it adheres to the side of the main frame 1. The cover 2 has a built-in handle 6, and the lower end of the main frame 1 has an anti-slip pad 15 with evenly distributed drainage grooves. In use, first insert your hand into the built-in handle 6 and rotate the cover 2 to open it. Then place the PCB board to be cleaned on the filter screen 3. After placement, close the cover 2. Then, place the PCB board... The main frame 1 of the PCB board is placed in the cleaning machine for cleaning. Magnet 2 14 is used to hold and fix the cover 2, preventing it from opening during transport and cleaning. The main frame 1 provides a transport platform for the PCB board. After the cover 2 is closed, the pressure strip 13 simultaneously squeezes the PCB board. Under this pressure, the micro-suction cup 10 firmly holds the PCB board in place, preventing collisions between the PCB boards within the main frame 1 and with the inner wall of the main frame 1 during transport, thus preventing scratches on the PCB board surface. The filter screen 3, after being pressed down, filters water... As the distance between the filter screen 3 and the adsorption magnet 12 decreases, the suction force increases, thus overcoming the elasticity of the spring 9. The filter screen 3 continues to move downward, causing the PCB board to detach from the pressure strip 13. This ensures the cleaning effect. After cleaning, the cover 2 is opened, and the worker holds the filter screen 3 by hand and pulls it upward, causing the filter screen 3 to detach from the adsorption of the adsorption magnet 12. The distance between the filter screen 3 and the adsorption magnet 12 increases, and the suction force decreases, which is insufficient to overcome the elasticity of the spring 9. The spring 9 can then support the filter screen 3, ensuring that the PCB board can be smoothly pressed and adsorbed by the micro suction cup 10 during the next cleaning.

[0024] When using it, first put your hand into the built-in handle 6 and rotate the cover 2 to open it. The cover 2 rotates through the hinge 4. Then place the PCB board to be cleaned on the filter screen 3. After placing it, close the cover 2. Then put the main frame 1 containing the PCB board into the cleaning machine to complete the cleaning. The magnet 14 is used to attract and fix the cover 2 to prevent the cover 2 from opening during transportation and cleaning.

[0025] The main frame 1 provides a transportation platform for PCB boards, thus preventing PCB boards of various sizes from falling out of the gaps between the tube rollers or being unable to pass through due to difficulty in pushing open the water deflector.

[0026] After the cover 2 is closed, the pressure strips 13 evenly distributed at the lower end of the filter screen 2 5 will simultaneously squeeze the PCB board. The pressure strips 13 are made of flexible rubber and will not damage the surface of the PCB board during the squeezing process. After the PCB board placed on the upper end of the filter screen 3 is subjected to the squeezing force, the micro suction cups 10 will firmly adhere to the PCB board, thus preventing the PCB boards in the main frame 1 from colliding with each other or with the inner wall of the main frame 1 during transportation, which would cause scratches on the surface of the PCB board. The anti-slip pad 15 is used to prevent the main frame 1 from slipping during transportation. The drainage grooves on the surface of the anti-slip pad 15 prevent water from adhering to the surface of the anti-slip pad 15, making it convenient for staff to pick up the main frame 1.

[0027] The filter screen 3 slides on the surface of the guide shaft 8 via the slider 11, thus ensuring the stability of the filter screen 3 as it moves downward. After the filter screen 3 is subjected to pressure and moves downward, the distance between the filter screen 3 and the adsorption magnet 12 decreases, and the attraction increases, thereby overcoming the elastic force of the spring 9. The adsorption magnet 12 will attract and drive the filter screen 3 to continue moving downward, causing the PCB board to detach from the contact with the pressure strip 13. This ensures the cleaning effect and prevents the contact area between the pressure strip 13 and the PCB board from being left uncleaned.

[0028] After cleaning, open the cover 2, and the worker holds the filter screen 3 with his hand and pulls it upward, so that the filter screen 3 is detached from the adsorption of the adsorption magnet 12. The distance between the filter screen 3 and the adsorption magnet 12 increases, and the attraction force decreases, which is not enough to overcome the elastic force of the spring 9. The spring 9 can then support the filter screen 3, ensuring that the PCB board can be smoothly pressed and adsorbed by the micro suction cup 10 during the next cleaning.

[0029] Through the above steps, the adjustable carrier board cleaning device provides a transportation platform for PCB board transportation. This avoids problems such as PCB boards falling out of the gap between the tube rollers and being unable to pass through due to difficulty in pushing open the water baffles, regardless of the type and size of the PCB boards being transported. After the cover 2 is closed, the pressure strip 13 will simultaneously squeeze the PCB boards. After the PCB boards are subjected to the squeezing force, the micro suction cup 10 will firmly adhere to all the PCB boards at the same time. This prevents the PCB boards from colliding with each other and with the inner wall of the main frame 1 during transportation, which would cause scratches on the surface of the PCB boards.
