Description

Technical Field

[0001] This utility model belongs to the field of flexible circuit board coating technology, specifically a coating device for flexible circuit board processing. Background Technology

[0002] Flexible printed circuit boards (FPCs) are highly reliable and extremely flexible printed circuit boards made from polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, thinness, and good bendability. The main raw materials include substrate, cover film, reinforcement, and other auxiliary materials. They are made by using photo-imaging pattern transfer and etching processes on the surface of a flexible substrate to create conductor circuit patterns.

[0003] A patent with publication number CN221288500U discloses a substrate coating device for flexible circuit board processing, relating to the field of coating device technology. It includes a support plate, a movable component fixedly connected to the surface of the support plate, a coating mechanism driven to the surface of the movable component, and a clamping mechanism on the surface of the support plate. The movable component includes a movable frame, which is fixedly connected to the surface of the support plate. This invention uses a motor to drive a screw to rotate, which in turn drives a connecting block to rotate, thereby achieving the effect of moving the coating mechanism back and forth for coating, making coating the circuit board more convenient. A motor drives a transmission roller to rotate, which in turn drives a belt to move a transmission block, which in turn moves a support frame, and consequently, the coating nozzle moves left and right for coating, achieving a flexible coating effect.

[0004] In the current technology, when existing flexible circuit boards are immersed in adhesive, the impact of the adhesive liquid and subsequent oscillation can cause the flexible circuit board to migrate or shift its position. If the flexible circuit board is directly clipped and fixed, it is not easy to remove the flexible circuit board later, which can easily lead to the problem of edge and corner damage to the flexible circuit board.

[0005] Therefore, a glue-applying device for flexible circuit board processing is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the above-mentioned problems, a glue-applying device for flexible circuit board processing is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The flexible circuit board processing adhesive application device of this utility model includes an immersion sealing box and a circuit board movably overlapping the inner wall of the immersion sealing box. Motors are provided on both sides of the immersion sealing box. Overlapping platforms are fixedly connected to the inner walls of both sides of the immersion sealing box. The bottom surface of the circuit board movably overlaps the top surface of the overlapping platforms. A sealing cover is movably overlapped on the top surface of the immersion sealing box. A U-shaped plate is fixedly installed on the inner wall of the bottom of the immersion sealing box and the inner wall of the sealing cover. An elastic wire is fixedly connected to the inner wall of the U-shaped plate. A silicone soft spike movably overlaps the bottom surface of the circuit board is fixedly connected to one end of the elastic wire.

[0008] Preferably, an air pump is fixedly installed on the top surface of the sealed cover, and suction pipes are fixedly installed on the top surface of the sealed cover and at the two side edges of the air pump. The input end of the air pump is fixedly connected to the outer surface of the suction pipe.

[0009] Preferably, the outer surface of the motor is provided with an overlap platform, and a hydraulic magnetic suction device is fixedly installed on the top surface of the overlap platform. The output end of the hydraulic magnetic suction device is magnetically attracted to the top surface of the closed cover.

[0010] Preferably, a limiting sleeve is fixedly installed on the outer surface of the output end of the motor, and a hydraulic rod is fixedly installed on one side surface of the limiting sleeve and at the two side edges.

[0011] Preferably, a slider is fixedly connected to the output end of the hydraulic rod, and the inner wall of the slider is movably sleeved on the outer surface of the motor output end.

[0012] Preferably, the upper and lower surfaces of the slider are fixedly connected to the extrusion soft plate, and the inner wall of the extrusion soft plate is movably overlapped with the outer surface of the soaking sealing box and the sealing cover, respectively.

[0013] Preferably, a glue-applying box is fixedly installed on the bottom surface of the limiting sleeve, and a glue guide tube is fixedly connected to the output end of the glue-applying box, with one end of the glue guide tube extending to the inner wall of the immersion sealing box.

[0014] The beneficial effects of this utility model are:

[0015] This utility model provides a gluing device for flexible circuit board processing. The circuit board is overlapped on the top surface of the silicone soft spikes. At this time, the sealing cover is placed on the top surface of the soaking and sealing box. The silicone soft spikes on the inner wall of the sealing cover are used to press down on the top surface of the circuit board. As the circuit board is continuously pressed down, the two side edges of the circuit board will overlap on the top surface of the overlapping platform. The overlapping platform is used to limit the height of the circuit board and the silicone soft spikes are used to limit the angle of the circuit board, so as to prevent the circuit board from shifting due to the rotation of the motor and the impact of the glue liquid.

[0016] This utility model provides a gluing device for processing flexible circuit boards. When the circuit board is confined inside the immersion sealing box, a hydraulic magnetic suction device is used to squeeze and push the sealing cover, so that the immersion sealing box and the sealing cover can be firmly closed together. At this time, a hydraulic rod on the outer surface of the limiting sleeve pushes the slider, so that the extrusion soft plate on the outer surface of the slider can overlap the outer surface of the immersion sealing box and the sealing cover, thereby limiting the position of the immersion sealing box and the sealing cover.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figures 1-5 This utility model provides a gluing device for processing flexible circuit boards, including an immersion sealing box 13 and a circuit board 14 movably overlapping the inner wall of the immersion sealing box 13. Motors 12 are provided on both sides of the immersion sealing box 13. Overlapping platforms 131 are fixedly connected to the inner walls of both sides of the immersion sealing box 13. The bottom surface of the circuit board 14 movably overlaps the top surface of the overlap platform 131. A closing cover 132 is movably overlapped on the top surface of the immersion sealing box 13. A U-shaped plate 135 is fixedly installed on the bottom inner wall of the immersion sealing box 13 and the inner wall of the closing cover 132. An elastic wire 136 is fixedly connected to the inner wall of the U-shaped plate 135. A silicone soft spike 137 movably overlaps the bottom surface of the circuit board 14 is fixedly connected to one end of the elastic wire 136.

[0028] During operation, the circuit board 14 is overlapped on the top surface of the silicone soft spikes 137. At this time, the sealing cover 132 is placed on the top surface of the soaking and sealing box 13. The silicone soft spikes 137 on the inner wall of the sealing cover 132 are used to press down on the top surface of the circuit board 14. As the circuit board 14 is continuously pressed down, the two side edges of the circuit board 14 will overlap on the top surface of the overlapping platform 131. The overlapping platform 131 is used to limit the height of the circuit board 14 and the silicone soft spikes 137 are used to limit the angle of the circuit board 14, so as to prevent the circuit board 14 from shifting due to the rotation of the motor 12 and the impact of the adhesive liquid.

[0029] After the adhesive is applied to the circuit board 14, the sealing cover 132 is removed, and the circuit board 14 is lifted by the elastic wire 136 inside the U-shaped plate 135, so that the circuit board 14 is moved from the inside of the immersion sealing box 13 to the top entrance of the immersion sealing box 13, which makes it convenient for employees to take and replace the circuit board 14 later.

[0030] Furthermore, such as Figure 4 As shown, a vacuum pump 133 is fixedly installed on the top surface of the sealing cover 132, and suction pipes 134 are fixedly installed on the top surface of the sealing cover 132 and on both sides of the vacuum pump 133. The input end of the vacuum pump 133 is fixedly connected to the outer surface of the suction pipe 134.

[0031] During operation, when the circuit board 14 is confined inside the immersion sealing box 13, when the adhesive liquid is poured into the immersion sealing box 13, the vacuum pump 133 is used to evacuate the air inside the suction pipe 134, thereby removing excess gas from the immersion sealing box 13. This ensures that the immersion sealing box 13 is completely filled with adhesive liquid, preventing air bubbles from adhering to the surface of the circuit board 14 during the immersion and adhesive liquid application, which would result in incomplete adhesive coating on the surface of the circuit board 14.

[0032] Furthermore, such as Figures 1 to 4 and Figure 6 As shown, an overlapping platform 11 is provided on the outer surface of the motor 12. A hydraulic magnetic suction device 15 is fixedly installed on the top surface of the overlapping platform 11. The output end of the hydraulic magnetic suction device 15 is magnetically attracted to the top surface of the sealing cover 132. A limiting sleeve 121 is fixedly installed on the outer surface of the output end of the motor 12. A hydraulic rod 122 is fixedly installed on one side surface of the limiting sleeve 121 and at the two side edges. A slider 123 is fixedly connected to the output end of the hydraulic rod 122. The inner wall of the slider 123 is movably sleeved on the outer surface of the output end of the motor 12. A compression flexible plate 124 is fixedly connected to the upper and lower sides of the slider 123. The inner wall of the compression flexible plate 124 is movably overlapping the outer surfaces of the immersion sealing box 13 and the sealing cover 132, respectively. A glue applicator 125 is fixedly installed on the bottom surface of the limiting sleeve 121. A glue guide tube 126 is fixedly connected to the output end of the glue applicator 125. One end of the glue guide tube 126 extends to the inner wall of the immersion sealing box 13.

[0033] During operation, when the circuit board 14 is confined inside the immersion sealing box 13, the hydraulic magnetic suction device 15 is used to squeeze and push the sealing cover 132, so that the immersion sealing box 13 and the sealing cover 132 can be firmly closed together. At this time, the hydraulic rod 122 on the outer surface of the limiting sleeve 121 pushes the slider 123, so that the extrusion soft plate 124 on the outer surface of the slider 123 can overlap the outer surface of the immersion sealing box 13 and the sealing cover 132, thereby limiting the position of the immersion sealing box 13 and the sealing cover 132.

[0034] After the soaking and sealing box 13 and the sealing cover 132 are completely closed, the adhesive liquid is poured into the adhesive guide tube 126 in conjunction with the adhesive coating box 125, and the adhesive liquid rises slowly inside the soaking and sealing box 13. As the adhesive liquid rises, it squeezes and discharges the gas inside the soaking and sealing box 13. At this time, the motor 12 swings the soaking and sealing box 13 left and right, so that the adhesive liquid swings back and forth inside the soaking and sealing box 13. The adhesive liquid under the swing will slide back and forth on the surface of the circuit board 14, and in the process of sliding, it will clean up the air bubbles left on the surface of the circuit board 14.

[0035] Working principle: The circuit board 14 is overlapped on the top surface of the silicone soft spikes 137. At this time, the sealing cover 132 is placed on the top surface of the soaking and sealing box 13. The silicone soft spikes 137 on the inner wall of the sealing cover 132 press down on the top surface of the circuit board 14. As the circuit board 14 is continuously pressed down, the two side edges of the circuit board 14 will overlap on the top surface of the overlapping platform 131. The overlapping platform 131 is used to limit the height of the circuit board 14 and the silicone soft spikes 137 are used to limit the angle of the circuit board 14, so as to prevent the circuit board 14 from shifting due to the rotation of the motor 12 and the impact of the adhesive.

[0036] After the adhesive is applied to the circuit board 14, the sealing cover 132 is removed. The elastic wire 136 inside the U-shaped plate 135 is used to lift the circuit board 14, so that the circuit board 14 moves from the inside of the immersion sealing box 13 to the top entrance of the immersion sealing box 13, which makes it easier for employees to take out and replace the circuit board 14 later.

[0037] When the circuit board 14 is confined inside the immersion sealing box 13, the hydraulic magnetic suction device 15 is used to squeeze and push the sealing cover 132, so that the immersion sealing box 13 and the sealing cover 132 can be firmly closed together. At this time, the hydraulic rod 122 on the outer surface of the limiting sleeve 121 pushes the slider 123, so that the extrusion soft plate 124 on the outer surface of the slider 123 can overlap the outer surface of the immersion sealing box 13 and the sealing cover 132, thereby limiting the position of the immersion sealing box 13 and the sealing cover 132.

[0038] After the soaking and sealing box 13 and the sealing cover 132 are completely closed, the adhesive liquid is poured into the adhesive guide tube 126 in conjunction with the adhesive coating box 125, and the adhesive liquid rises slowly inside the soaking and sealing box 13. As the adhesive liquid rises, it squeezes and discharges the gas inside the soaking and sealing box 13. At this time, the motor 12 swings the soaking and sealing box 13 left and right, so that the adhesive liquid swings back and forth inside the soaking and sealing box 13. The adhesive liquid under the swing will slide back and forth on the surface of the circuit board 14, and in the process of sliding, it will clean up the air bubbles left on the surface of the circuit board 14.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
