Description
Technical Field

[0002] In the field of printed circuit board (PCB) manufacturing, the adhesive coating process is a key step in ensuring the electrical performance and mechanical stability of the circuit board. As electronic products become smaller and more integrated, higher requirements are placed on the precision, uniformity, and efficiency of adhesive coating for printed circuit boards.
[0003] Traditional adhesive coating equipment often uses a two-way lead screw or two electric push cylinders to clamp two clamping plates in opposite directions. This makes it difficult to adapt to printed circuit boards of different sizes and shapes, and the clamping process is cumbersome, resulting in low clamping efficiency and failing to meet diverse production needs. At the same time, due to ambient temperature during the adhesive coating process, the adhesive is prone to sedimentation and stratification, affecting the coating quality and easily causing problems such as uneven coating and stringing. Therefore, improvements are needed to address these issues. Utility Model Content

[0019] Example: See Figure 1-4This utility model discloses a printing circuit board coating device, comprising an electric push cylinder 1, a top plate fixedly connected to the electric push cylinder 1, two side plates 2 fixedly connected to both sides of the bottom surface of the top plate, a worktable fixedly connected to the bottom end of the side plates 2, a rotating platform provided in the middle of the top surface of the worktable, a mounting plate 7 fixedly connected to the top surface of the rotating platform, a clamping assembly mounted on the mounting plate 7, a lifting plate fixedly connected to the telescopic rod of the electric push cylinder 1, guide grooves provided on the opposite surfaces of the two side plates 2, the two ends of the lifting plate extending into the guide grooves, a glue tank 4 provided at one point on the top surface of the lifting plate, and a first... A motor 5; one of the two side plates 2 has a through slot at the guide groove; one end of the lifting plate passes through the through slot and is fixed to a connecting plate; a second motor 6 is installed on the bottom surface of the connecting plate; a DT50 electric push cylinder 1 has high thrust and precision, and works with the side plate 2 and the lifting plate to achieve precise and flexible adjustment of the glue application height; a mounting plate 7 is combined with the clamping assembly to facilitate quick fixation of printed circuit boards of different sizes; the guide groove guides the lifting plate, ensuring a smooth and precise glue application process, improving glue application efficiency and stability; the lifting plate... A first lead screw 8 is rotatably mounted on the bottom surface of the lowering plate. A second slider 9 is sleeved on the first lead screw 8. One end of the first lead screw 8 is coaxially fixed to a second motor 6. An outer barrel is mounted on the bottom surface of the second slider 9. The second motor 6, model Y80M1-2, drives the first lead screw 8 to rotate, causing the second slider 9 and the outer barrel to move horizontally, realizing flexible adjustment of the nozzle position. This can adapt to different glue application path requirements and improve the flexibility and adaptability of glue application. A fan 14 is installed on the top surface of the outer barrel. An air pipe 15 is connected and fixed to the output shaft of the fan 14. A fixing block is fixed to the lower end of the outer wall of the barrel. The fixing block has a through hole for the air pipe 15 to pass through. The end of the air pipe 15 is equipped with a nozzle, which is horn-shaped. The fan 14, model PF-125P, delivers airflow to the horn-shaped nozzle through the air pipe 15 to clean the surface of the circuit board and remove dust and impurities before applying the adhesive. The air pipe 15 is made of nickel-titanium alloy shape memory metal. Due to its shape memory function, it can maintain a stable shape in different environments, ensuring a stable airflow path, improving the adhesion of the adhesive, and improving the coating quality.
[0020] In this invention, a stirring blade 12 is rotatably mounted inside the glue tank 4, with one end of the stirring blade 12 coaxially fixed to the first motor 5. An inlet pipe 11 is connected to the lower end of the inner wall of the glue tank 4. A heating tank 13 is installed inside the outer tank, with one end of the inlet pipe 11 connected to the top surface of the heating tank 13. A heat insulation layer 16 is attached to the inner wall of the outer tank. A discharge pipe is located at the bottom of the heating tank 13, extending out of the outer wall at the bottom of the outer tank. The first motor 5, model Y80M1-2, drives the stirring blade 12 to prevent the glue from settling and separating. The heating tank 13, model JR-20, works in conjunction with the heat insulation layer 16 made of aerogel felt. The excellent heat insulation performance of the aerogel felt effectively reduces heat loss, maintains a stable glue temperature, ensures glue fluidity, avoids uneven coating and stringing problems, and improves coating quality. The clamping assembly includes sliding grooves arranged in a cross pattern on the top surface of the mounting plate 7. A second lead screw 17 is rotatably mounted within the sliding groove, and a first slider is sleeved on each of the second lead screws 17. 3. One end of the first slider 3 is slidably mounted on the top surface of the mounting plate 7 through the sliding groove. The inner bottom surface of the mounting plate 7 is rotatably equipped with an active bevel gear 19. One end of the second lead screw 17 is coaxially fixed with a driven bevel gear 18 that meshes with the active bevel gear 19. The third motor 10, model Y80M1-2, drives the active bevel gear 19, which in turn drives the second lead screw 17 to rotate synchronously through the driven bevel gear 18. This enables the first slider 3 to achieve multi-directional synchronous clamping, which can adapt to printed circuit boards of different sizes and shapes, improving clamping efficiency and stability. The bottom surface of the worktable is equipped with the third motor 10, which is coaxially fixed with the active bevel gear 19. The first slider 3 is L-shaped, and the air pipe 15 is made of shape memory metal. The third motor 10, model Y80M1-2, provides stable power to ensure reliable operation of the clamping components. The L-shaped first slider 3 effectively fixes the circuit board. The shape memory metal air pipe 15 can maintain a stable shape, ensuring airflow delivery effect and improving cleaning and adhesive coating quality.
[0021] Working principle: When using this utility model, the third motor 10 on the bottom surface of the workbench is first started to drive the active bevel gear 19 to rotate. Through meshing with the driven bevel gear 18, the second lead screw 17, which is arranged in a cross shape, rotates synchronously. This causes the L-shaped first slider 3, which is sleeved on the second lead screw 17, to slide in the sliding groove, thereby achieving quick clamping and fixing of printed circuit boards of different sizes and shapes on the mounting plate 7. Then, the electric push cylinder 1 is started, and its telescopic rod drives the lifting plate to move up and down in the guide groove of the side plate 2 to adjust the glue application height. At the same time, the first motor 5 on the top surface of the glue tank 4 drives the... The stirring blades 12 rotate to prevent the adhesive from settling or separating. The uniformly stirred adhesive flows into the heating tank 13 through the feed pipe 11. The heating tank 13, together with the insulation layer 16 on the inner wall of the outer tank, maintains a stable temperature for the adhesive. Then, the second motor 6 on the bottom of the connecting plate drives the first lead screw 8 to rotate, causing the second slider 9 to move the outer tank horizontally to adjust the position of the nozzle. The fan 14 on the top of the outer tank delivers airflow to the trumpet-shaped nozzle through the air pipe 15 to clean the surface of the printed circuit board. Finally, the adhesive in the heating tank 13 flows out through the discharge pipe, completing the precise application of adhesive. At this point, the device is in use.
