[0001] The utility model relates to the technical field of printed circuit production, in particular to a surface polishing device for laminated steel plates used for printed circuits. Background Art

[0002] The laminating / separating steel plate is mainly used in the lamination process of PCB printed circuit boards; it is the lamination mold used to press the copper foil, film and the inner layer circuit board after oxidation treatment into a multi-layer substrate.

[0020] The embodiment of the present application provides a surface polishing device for laminated steel plates for printed circuits, which effectively solves the problem of surface polishing of steel plates by grinding wheels. During the grinding process, debris and impurities will be generated on the surface of the steel plate and remain on the surface of the steel plate, affecting the cleanliness of the steel plate and affecting the staff's observation of the polishing progress of the steel plate. The pull rod applies a downward thrust to the blowing plate, which rotates around the top end. At the same time, the blowing plate drives the air pipe to bend and stretch. The blowing plate is flipped downward by the push of the pull rod, and the air blowing device on one side of the base transports air to the inside of the blowing plate through the air pipe, and then discharges air from one side of the blowing plate. When the polishing module grinds and polishes the steel plate, the airflow blown out by the connecting rod cleans the impurities polished on the surface of the steel plate, and cleans and collects the debris to ensure the cleanliness of the steel plate.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that during the surface polishing of the steel plate by the grinding wheel, debris and impurities will be generated on the surface of the steel plate and remain on the surface of the steel plate, affecting the cleanliness of the steel plate and affecting the staff's observation of the polishing progress of the steel plate. The overall idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a surface polishing device for laminated steel plates for printed circuits, including a base 1, two first drive seats 12 are fixedly installed inside the base 1, and two second drive seats 13 are movably installed on the side ends of each first drive seat 12. A blowing plate 11 is rotatably installed on the inner side wall of the base 1, and pull rods 19 are rotatably installed on the two side ends of the blowing plate 11. The blowing plate 11 is flipped downward by the push of the pull rod 19. The blowing device on one side of the base 1 transports air to the inside of the blowing plate 11 through the air pipe 18, and the air is discharged from one side of the blowing plate 11. When the polishing module 24 grinds and polishes the steel plate, the airflow blown out by the connecting rod 14 cleans the impurities polished on the surface of the steel plate. Two air pipes 18 are fixedly installed on the top of the blowing plate 11, a discharge port 16 is opened at the top of the base 1, and an intercepting plate 15 is fixedly installed on the top of the base 1.

[0024] The same polishing module 24 is fixedly installed on the side ends of the two second driving seats 13, and the two inner side walls of the base 1 are fixedly installed with a fixed plate 17, and a slider 21 is slidably installed inside the fixed plate 17. The side ends of the slider 21 are fixedly installed with a fixed block 23, and the top of each fixed block 23 is fixedly installed with a telescopic plate 22. The two side ends of the polishing module 24 are fixedly installed with a connecting rod 14, and two driving rods 25 are fixedly installed inside the first driving seat 12. The steel plate is placed inside the base 1, and the first driving seat 12 and the second driving seat 13 are driven. The driving rods 25 inside the first driving seat 12 and the second driving seat 13 are synchronously retracted and extended, pushing the second driving seat 13 to slide horizontally inside the first driving seat 12. At the same time, the polishing module 24 slides vertically on the inner side of the second driving seat 13, and the position of the grinding roller at the bottom end of the polishing module 24 is adjusted to allow the polishing module 24 to polish the surface of the steel plate.

[0025] Working principle:

[0026] The first step is to place the steel plate inside the base 1 when in use, and drive the first drive seat 12 and the second drive seat 13. The drive rods 25 inside the first drive seat 12 and the second drive seat 13 are synchronously extended and retracted, pushing the second drive seat 13 to slide horizontally inside the first drive seat 12, and at the same time, the polishing module 24 slides vertically inside the second drive seat 13, and the position of the grinding roller at the bottom end of the polishing module 24 is adjusted, so that the polishing module 24 polishes and grinds the surface of the steel plate, and at the same time, the polishing module 24 is driven by the second drive seat 13 to slide inside the second drive seat 13 to grind the surface of the steel plate. The upward movement drives the connecting rod 14 to move synchronously, and the connecting rod 14 drives the slider 21 to slide downward inside the fixed plate 17. At the same time, the slider 21 rotates with the pull rod 19, so that the pull rod 19 applies a downward thrust to the blowing plate 11, allowing the blowing plate 11 to rotate around the top. At the same time, the blowing plate 11 drives the air pipe 18 to bend and stretch. Through the push of the pull rod 19, the blowing plate 11 is flipped downward, and the blowing equipment on one side of the base 1 transports air to the inside of the blowing plate 11 through the air pipe 18, and then discharges air from one side of the blowing plate 11. When the polishing module 24 grinds and polishes the steel plate, the airflow blown out by the connecting rod 14 cleans the impurities polished on the surface of the steel plate.

[0027] In the second step, the airflow blows the impurities to one side. When the impurities move to one side along the inside of the base 1 and are intercepted by the interception plate 15, the impurities fall into the inside of the discharge port 16 and are directly discharged from the inside of the base 1 to ensure the cleanliness of the internal processing of the base 1. At the same time, the polishing module 24 is driven to move upward by the second driving seat 13. After the polishing module 24 leaves the surface polishing processing of the steel plate, it moves upward, driving the connecting rod 14 to move upward, allowing the slider 21 to apply an upward force to the pull rod 19, and the blowing plate 11 is flipped upward. At the same time, the slider 21 drives the fixed block 23 to move upward, squeezing the bottom end of the telescopic plate 22. The telescopic plate 22 is first stretched and retracted to a certain extent under the force. At the same time, when the telescopic plate 22 is stretched to the limit position, the fixed block 23 pushes the telescopic plate 22 to move upward, squeezing the valve inside the fixed plate 17, so that the fixed plate 17 and the air pipe 18 are disconnected from each other, and the blowing plate 11 is flipped upward for storage, while the airflow is cut off.

[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
