[0002] A circuit board is a substrate that carries electronic components. It is an important component in electronic equipment and electrical control systems. Various electronic components, such as capacitors, resistors, integrated circuits, and crystal oscillators, are arranged on the circuit board. The circuit functions through the connections on the printed circuit board. Circuit board dispensing is the process of applying special adhesive to the surface of the circuit board, allowing it to cure and form a protective film.

[0003] When applying adhesive to circuit boards, a fixing device is usually required to hold the circuit board in place. Existing fixing devices may cause deformation or damage to the circuit board due to excessive clamping force. Furthermore, when changing to circuit boards of different sizes, the clamps need to be readjusted, which is relatively cumbersome. In order to address this technical problem, this application proposes a circuit board adhesive fixing device. Utility Model Content

[0022] 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.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a circuit board adhesive fixing device, comprising a workbench 1. The workbench 1 has grooves 6 on both the front and rear sides of its upper end. A rotating rod 9 is rotatably connected to the middle of the groove 6. A gear 10 is fixedly connected to the outer wall of the rotating rod 9. Two racks 8 are meshed with the outer walls of the gear 10. Slider 7s are fixedly connected to the ends of the two racks 8. The outer walls of opposite ends of the racks 8 are slidably connected to the inner wall of the groove 6. The lower end of the slider 7 is slidably connected to the inner wall of the groove 6. A groove is formed at the opposite end of the slider 7, the size of which is the same as that of the racks 8. The dimensions are matched. The upper end of the slider 7 is fixedly connected to the movable plate 2. The inside of the movable plate 2 is slidably connected to the slide rod 11. The opposite end of the slide rod 11 is fixedly connected to the L-shaped clamp 4. The outside of the slide rod 11 is fitted with a compression spring 12. One end of the compression spring 12 is fixedly connected to the inside of the movable plate 2. The other end of the compression spring 12 is fixedly connected to the opposite end of the L-shaped clamp 4. The upper end of the L-shaped clamp 4 is fixedly connected to the elastic rubber pad 5. The upper left side of the worktable 1 is equipped with an electric push rod 3. The drive end of the electric push rod 3 is fixedly connected to the left end of the left movable plate 2.

[0024] Specifically, when fixing the circuit board, the circuit board is first placed on two L-shaped clamping plates 4. Then, the electric push rod 3 is activated. The drive end of the electric push rod 3 drives the left movable plate 2 and the L-shaped clamping plate 4 to move to the right, which in turn drives the slider 7 and rack 8 under the left L-shaped clamping plate 4 to slide. The sliding of the left rack 8 drives the gear 10 to rotate, which in turn drives the right rack 8 and slider 7 to slide. The right slider 7 drives the right movable plate 2 to slide, which in turn drives the right L-shaped clamping plate 4 to move to the left, clamping and fixing the circuit board. The elastic rubber pad 5 set on the L-shaped clamping plate 4 can improve the stability and reliability of the circuit board fixing. The compression spring 12 set on the rear side of the L-shaped clamping plate 4 can absorb shock during clamping and fixation, avoiding deformation or damage to the circuit board due to excessive clamping force, which would affect the efficiency of the circuit board adhesive application. Furthermore, by adjusting the distance between the two L-shaped clamping plates 4, it is convenient to clamp circuit boards of different sizes, thereby improving the applicability of the device.

[0025] Reference Figure 1 and Figure 4 A heat-conducting plate 14 is fixedly connected to the upper middle part of the workbench 1. A heating frame 15 is installed on the lower side of the heat-conducting plate 14. The end of the heating frame 15 is fixedly connected to the inside of the workbench 1. A fan 17 is installed on the lower side of the heating frame 15. A guide plate 16 is fixedly connected to the upper end of the fan 17. A protective cover 18 is installed on the lower side of the fan 17. The end of the protective cover 18 is fixedly connected to the lower inside of the workbench 1. A control panel 13 is installed on the upper right side of the workbench 1 for controlling the heating temperature.

[0026] Specifically, after the circuit board is clamped and fixed, the fan 17 and heating frame 15 can be turned on. The air blown by the fan 17 blows the hot air from the heating frame 15 through the heat conduction plate 14 to the circuit board through the air guide plate 16, thereby preheating the circuit board and improving the adhesive application effect. The heating temperature can be controlled by the control panel 13, so that after the circuit board is coated with adhesive, the adhesive can be dried quickly by heating the circuit board, thereby improving the efficiency of the adhesive application.

[0027] Working principle: When applying adhesive to the circuit board, firstly, according to the size of the circuit board, the electric push rod 3 is activated. The drive end of the electric push rod 3 drives the left movable plate 2 to move to the right, which in turn drives the left slider 7 and rack 8 to slide to the right. The left rack 8 drives the gear 10 to rotate, which in turn drives the right rack 8 and slider 7 to slide to the left, causing the right movable plate 2 to move to the left, thereby adjusting the distance between the two L-shaped clamps 4. When the L-shaped clamps 4 move to the appropriate distance, the circuit board is placed on the L-shaped clamps 4. Then, the electric push rod 3 is activated again, so that the L-shaped clamps 4 can clamp and fix the circuit board. Then, the fan 17 and the heating frame 15 are activated. The fan 17 blows the hot air emitted by the heating frame 15 onto the circuit board, which can preheat the circuit board and improve the adhesive application effect. The heating temperature can be controlled through the control panel 13, so that the adhesive can dry quickly after the circuit board is coated, thereby improving the efficiency of the circuit board coating.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
