Description

Technical Field

[0001] This utility model relates to the field of solder resist printing technology, specifically to a scraper mechanism for solder resist printing. Background Technology

[0002] Printed circuit boards (PCBs) are fundamental components in the electronics industry. Solder resist printing is used to prevent short circuits during component insertion and to save on solder usage. The solder resist process involves evenly covering the PCB with solder resist ink in designated areas. During solder resist printing, a squeegee is used to evenly scrape away the ink, preventing excessive ink adhesion and accumulation that could affect the printing process. While some existing squeegee mechanisms for solder resist printing allow adjustment of the distance between the squeegee body and the surface being scraped, facilitating ink removal, they cannot change the contact angle of the squeegee body when encountering surfaces with different angles, resulting in poor scraping performance and impacting the efficiency of the squeegee mechanism. Utility Model Content

[0003] In view of this, the present invention provides a squeegee mechanism for solder resist printing, which can not only adjust the distance between the squeegee body and the scraping surface to facilitate ink scraping, but also adjust the angle of the squeegee body to ensure the ink scraping effect and improve the working efficiency of the squeegee mechanism.

[0004] To solve the above technical problems, this utility model provides a scraper mechanism for anti-welding printing, including a mounting plate, a fixing block at the upper end of the mounting plate, and an adjustment component inside the fixing block;

[0005] The adjustment assembly includes a cylinder housed inside a fixed block. A movable block is fixedly connected to the telescopic end of the cylinder. A rotating shaft is rotatably connected inside the movable block, and a connecting seat is provided on the surface of the rotating shaft. A first hinge seat is provided on the inner wall of the movable block, and an electric push rod is hinged within the first hinge seat. A second hinge seat is provided on the rotating shaft, and a connecting rod is hinged within the second hinge seat. The telescopic end of the electric push rod is rotatably connected to the bottom of the connecting rod via a support rod. During operation, the operator can activate the cylinder to extend the movable block, adjusting the distance between the scraper body and the scraping surface by adjusting the extension distance of the movable block. Then, the operator can activate the electric push rod, which, under the action of the hinge, drives the rotating shaft to rotate, thereby adjusting the angle of the scraper body. This facilitates the alignment of the scraper body with scraping surfaces at different angles, making the removal of solder resist ink easier.

[0006] The electric actuator is located on the inner bottom side of the moving block, and the second hinge seat is located on the middle bottom side of the rotating shaft.

[0007] The upper end of the connector is connected to a connecting plate by screws. The upper end of the connecting plate is equipped with a scraper body, which can be replaced by unscrewing the screws.

[0008] Two symmetrical grooves are provided on the upper end of the fixed block, and sliding blocks are slidably connected in both grooves. Both sliding blocks are connected to the moving block, and the sliding blocks ensure the stability of the moving block when it moves.

[0009] The fixed block has multiple limiting rods inside, each of which is slidably connected to the moving block. The limiting rods can not only limit the movement of the moving block, but also further ensure the sliding stability of the moving block.

[0010] Mounting holes are provided at all four corners of the mounting plate, allowing workers to fix the mounting plate in the appropriate position.

[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0012] 1. When using this utility model, not only can the distance between the scraper body and the scraping surface be adjusted to facilitate the scraping of ink, but the angle of the scraper body can also be adjusted to ensure the scraping effect of ink and improve the working efficiency of the scraper mechanism.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] According to one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown: This embodiment provides a squeegee mechanism for solder resist printing, including a mounting plate 100, a fixing block 200 at the upper end of the mounting plate 100, and an adjustment component 300 inside the fixing block 200;

[0023] The adjusting assembly 300 includes a cylinder 301 disposed inside the fixed block 200. A movable block 302 is fixedly connected to the telescopic end of the cylinder 301. A rotating shaft 303 is rotatably connected inside the movable block 302. A connecting seat 304 is disposed on the surface of the rotating shaft 303. A first hinge seat 305 is disposed on the inner wall of the movable block 302. An electric push rod 306 is hingedly disposed inside the first hinge seat 305. A second hinge seat 307 is disposed on the rotating shaft 303. A connecting rod 308 is hingedly disposed inside the second hinge seat 307. The telescopic end of the electric push rod 306 is rotatably connected to the connecting rod 308 via a support rod. At the bottom, during operation, the operator can activate cylinder 301 to extend moving block 302. The distance of extension of moving block 302 can be used to adjust the distance between the scraper body 402 and the scraping surface. Then, the operator can activate electric push rod 306. Under the action of hinge, as the telescopic end of electric push rod 306 extends and retracts, the connecting rod 308 and electric push rod 306 can change, thereby driving the rotating shaft 303 to rotate. This achieves angle adjustment of scraper body 402, making it convenient for scraper body 402 to correspond to scraping surfaces at different angles, thus facilitating the scraping of solder resist ink.

[0024] According to another embodiment of the present invention, such as Figure 1 , Figure 2and Figure 4 As shown, the electric push rod 306 is located on the inner bottom side of the moving block 302, the second hinge seat 307 is located on the middle bottom side of the rotating shaft 303, the upper end of the connecting seat 304 is connected to the connecting plate 401 by screws, the upper end of the connecting plate 401 is provided with the scraper body 402, and the scraper body 402 can be replaced by unscrewing the screws. The upper end of the fixed block 200 has two symmetrically opened sliding grooves 501, and sliding blocks 502 are slidably connected in both sliding grooves 501. Both sliding blocks 502 are connected to the moving block. The sliding block 502 is connected to the moving block 302, which ensures the stability of the moving block 302 during movement. The fixed block 200 is provided with multiple limiting rods 600 inside, and each limiting rod 600 is slidably connected to the moving block 302. The limiting rods 600 can not only limit the movement of the moving block 302, but also further ensure the sliding stability of the moving block 302. The four corners of the surface of the mounting plate 100 are provided with mounting holes 700, and the staff can fix the mounting plate 100 in a suitable position through the mounting holes 700.

[0025] The method of using this utility model is as follows: During operation, the operator can activate the cylinder 301, causing the moving block 302 to extend. The distance of the extension of the moving block 302 is used to adjust the distance between the scraper body 402 and the scraping surface. Subsequently, the operator can activate the electric push rod 306. Under the action of hinge, as the telescopic end of the electric push rod 306 extends and retracts, the connecting rod 308 and the electric push rod 306 can change, thereby driving the rotating shaft 303 to rotate. This achieves the angle adjustment of the scraper body 402, making it convenient for the scraper body 402 to correspond to the scraping surface at different angles, thus facilitating the scraping of solder resist ink. This utility model can not only adjust the distance between the scraper body 402 and the scraping surface to facilitate the scraping of ink, but also adjust the angle of the scraper body 402, ensuring the scraping effect of ink and improving the working efficiency of the scraper mechanism.

[0026] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
