A gluing device for electronic component manufacturing

Abstract

This utility model discloses a glue-applying device for electronic component production, belonging to the technical field of glue-applying devices. It includes a glue-applying box with a glue storage chamber inside. A lifting roller brush is installed in the glue storage chamber, and a positioning channel is embedded and fixed on one side surface of the glue-applying box. This utility model uses a drive motor to rotate a lifting screw, which in turn drives the lifting roller brush to move up and down. During the rising and falling reset process, the roller brush shell is applied to the end of the component to be coated twice by the brush bristles that adhere to the glue. This bidirectional rolling glue-applying method effectively avoids omissions or unevenness that may occur with single-application, ensuring that every part of the surface to be coated is evenly covered with glue, significantly improving the glue-applying quality. The positioning channel allows for precise positioning of the component, ensuring that the position of the end to be coated is consistent each time glue is applied, thus ensuring the stability of the glue-applying effect.

Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, specifically an adhesive coating equipment for the production of electronic components. Background Technology

[0002] In the production process of electronic components, the adhesive coating process is a key step to ensure the assembly accuracy, electrical performance and service life of the components. In the existing technology, the adhesive coating equipment for electronic components mostly adopts a fixed roller brush or nozzle type adhesive coating structure.

[0003] Among these devices, those using fixed roller brushes have a fixed position and non-adjustable height. When the remaining glue in the coating box decreases, the roller brush cannot fully contact the glue, resulting in insufficient glue adhesion to the brush bristles. This can easily lead to problems such as missed coatings and excessively thin coatings during subsequent coating processes. Furthermore, these devices are not conducive to centralized glue distribution; the glue is dispersed within the storage box, and residual glue is difficult for the roller brush to fully utilize, resulting in waste. Existing devices mostly perform coating actions in a unidirectional manner, making it difficult to compensate for the shortcomings of single-pass coating through bidirectional coating. This makes it difficult to meet the stringent coating quality requirements of high-precision electronic components. Therefore, a coating device for electronic component production is needed to solve the problems existing in the current technology. Utility Model Content

[0004] The purpose of this invention is to provide a coating device for the production of electronic components, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating device for electronic component production, comprising a coating box, an adhesive storage chamber inside the coating box, a lifting roller brush disposed in the adhesive storage chamber, a positioning channel embedded and fixed on one side surface of the coating box, the lifting roller brush comprising a roller brush shell, a lifting rotating frame and a lifting slider, the lifting rotating frame being slidably connected in a slide rail of the coating box, the roller brush shell being rotatably sleeved on the outside of the lifting rotating frame, the lifting slider being fixed at one end of the lifting rotating frame, and a bristle sleeve being fixedly sleeved on the outside of the roller brush shell.

[0006] Preferably, the upper end face of the lifting slider is provided with a lifting screw hole, and the internal thread of the lifting screw hole is through which a lifting lead screw passes.

[0007] Preferably, a lifting groove is provided on one inner wall of the glue coating box, and the lifting screw is rotatably connected in the lifting groove of the glue coating box.

[0008] Preferably, the lifting slider is slidably connected in the lifting groove of the glue application box.

[0009] Preferably, a drive motor is fixed to the upper end face of the glue application box, and the lifting screw extends out of the upper end of the glue application box and is fixed to the output shaft of the drive motor.

[0010] Preferably, the inner bottom wall of the glue application box is fixed with a glue guiding inclined block, and a glue collection space is provided on one side of the glue guiding inclined block.

[0011] This utility model provides a coating device for the production of electronic components, which has the following advantages compared with the prior art:

[0012] The drive motor rotates the lifting screw, which in turn drives the lifting slider to lift the roller brush. During the lifting and lowering process, the roller brush shell is rolled and coated twice by the brush bristles that hold the adhesive. This bidirectional rolling coating method effectively avoids the omissions or unevenness that may occur with single coating, ensuring that every part of the object to be coated is evenly covered with adhesive, greatly improving the coating quality. The positioning channel can accurately position the object, ensuring that the position of the object to be coated is consistent each time adhesive is applied, thus ensuring the stability of the coating effect.

[0013] With its adjustable lifting roller and guide block, the guide block in the glue dispensing box directs the glue to the collection space, concentrating it directly below the lifting roller. When the lifting roller descends and returns to its original position in the glue, the brush bristles fully absorb the glue, laying the foundation for even coating. Simultaneously, the adjustable height of the lifting roller accommodates varying amounts of glue in the dispensing box. Even with limited glue remaining, adjusting the height ensures the brush bristles are fully coated, and combined with the guide block's ability to concentrate residual glue, this significantly reduces glue waste and maximizes the utilization of small amounts of glue.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a glue coating device for electronic component production, including a glue coating box 1, a glue storage chamber 2 inside the glue coating box 1, a lifting roller brush 3 in the glue storage chamber 2 of the glue coating box 1, a positioning channel 4 embedded and fixed on one side surface of the glue coating box 1, the lifting roller brush 3 including a roller brush shell 5, a lifting rotating frame 7 and a lifting slider 9, the lifting rotating frame 7 being slidably connected in the slide of the glue coating box 1, the roller brush shell 5 being rotatably sleeved on the outside of the lifting rotating frame 7, the lifting slider 9 being fixed to one end of the lifting rotating frame 7, and a bristle sleeve 6 being fixedly sleeved on the outside of the roller brush shell 5; first, the glue to be coated is placed in the glue coating box 1. One end of the adhesive object is precisely placed into the positioning channel 4, ensuring it is flush with the port. Then, the drive motor 11 is started. This action will drive the lifting screw 8 to rotate in the lifting slide 12 of the adhesive box 1. Since the lifting slider 9 and the lifting screw 8 are connected by threads, the rotation of the lifting screw will drive the lifting roller brush 3 to rise inside the adhesive box 1. When the lifting roller brush 3 descends and resets, it will be attached to the coating end of the object again for a second coating. Through such two coating operations, the comprehensiveness of the coating on the object's surface can be effectively guaranteed, avoiding problems such as missed coating or insufficient coating.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the upper end face of the lifting slider 9 is provided with a lifting screw hole 10, and the internal thread of the lifting screw hole 10 passes through the lifting screw 8. The inner wall of one side of the glue coating box 1 is provided with a lifting slide groove 12. The lifting screw 8 is rotatably connected in the lifting slide groove 12 of the glue coating box 1, and the lifting slider 9 is slidably connected in the lifting slide groove 12 of the glue coating box 1. The upper end face of the glue coating box 1 is fixed with a drive motor 11, and the lifting screw 8 extends out of the upper end of the glue coating box 1 and is fixed on the output shaft of the drive motor 11. When the lifting roller brush 3 descends and resets and is immersed in the glue, the bristle sleeve 6 outside the roller brush shell 5 will fully absorb the glue, thus reserving a sufficient and uniform amount of glue for the subsequent uniform roller coating work.

[0022] Further as Figure 1As shown, it is worth noting that the inner bottom wall of the glue coating box 1 is fixed with a glue guiding inclined block 13, and a glue collection space 14 is provided on one side of the glue guiding inclined block 13. In actual use, the glue inside the glue coating box 1 will be guided by the glue guiding inclined block 13 and flow into the glue collection space 14 directly below the lifting roller brush 3. In addition, the lifting roller brush 3 has the feature of height adjustment. This design allows it to adapt to different amounts of glue in the glue coating box 1, ensuring that the brush bristle sleeve 6 effectively adheres to the glue. At the same time, in conjunction with the glue guiding inclined block 13 to concentrate the residual glue in the glue collection space 14 area, it can further improve the utilization rate of the small amount of glue in the glue coating box 1, reduce glue waste, and reduce production costs.

[0023] This solution has the following working process: During the production of electronic components, one end of the object to be coated is placed into the positioning channel 4 and flush with the port. Then, the drive motor 11 is started, which drives the lifting screw 8 to rotate in the lifting slide 12 of the coating box 1. The lifting slider 9, which is threadedly connected to the lifting screw 8, drives the lifting roller brush 3 to rise inside the coating box 1. During the process of the roller brush shell 5 rising, since the roller brush shell 5 is fixedly rotated on the lifting frame 7, the roller brush shell 5 rolls on the end of the object to be coated by the brush bristles 6 with glue attached to it to achieve the glue coating operation. When the lifting roller brush 3 falls and resets, it reattaches to the coating end of the object for a second glue coating operation, thereby ensuring the full coverage of the object to be coated.

[0024] During use, the glue inside the glue application box 1 is guided by the glue guide 13 and concentrated in the glue collection space 14 directly below the lifting roller brush 3. When the lifting roller brush 3 descends and resets to the glue, the bristle sleeve 6 on the outside of the roller brush shell 5 fully absorbs the glue for subsequent uniform rolling. The height of the lifting roller brush 3 is adjustable to accommodate different amounts of glue in the glue application box 1. In addition, the glue guide 13 helps to concentrate the residual glue in the glue collection space 14 area, which can further improve the utilization rate of the small amount of glue in the glue application box 1.
