Description

Technical Field

[0001] The present invention relates to the technical field of PCBA board processing, and in particular to an automatic glue coating device for PCBA board assembly. Background Art

[0002] The names of circuit boards include: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high-frequency board, thick copper board, impedance board, ultra-thin circuit board, ultra-thin circuit board, printed circuit board, etc. The circuit board miniaturizes and visualizes the circuit, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances.

[0003] The glue coating on the surface of the PCBA board is mainly to improve the protection performance and functionality. In terms of protection, it can isolate moisture, dust, and chemical erosion, prevent oxidation and corrosion from causing circuit damage, extend the service life, and ensure stability and reliability. At the functional level, specific coatings can adjust electrical characteristics. For example, insulating paint can precisely control the electrical insulation between circuits, and some coatings help with heat dissipation, maintaining an appropriate working temperature to ensure the efficient operation of the circuit board.

[0004] The traditional method of glue coating on the PCBA board relies on glue coating equipment for operation. In order to improve the glue coating quality, it is necessary to clean the surface of the circuit board before glue coating. After cleaning, it is manually taken and placed in the glue coating equipment. This transfer operation has the problem of contaminating the circuit board. Moreover, during the glue coating operation of the glue coating equipment, only the nozzle structure moves. When the circuit board is being cleaned, the coating in the glue coating equipment will be static due to the structure, resulting in uneven mixing of the coating, which may cause the problem of subsequent coating blocking the nozzle, thus affecting the uniformity of glue coating on the circuit board.

[0005] Based on this, an automatic glue coating device for PCBA board assembly is proposed. Summary of the Invention

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0029] An automatic glue - applying device for PCBA board assembly, including a base 1. At the upper end of the base 1, there are side plates 2, a motor cover 10 and a glue - applying frame 9 connected. The side plates 2 are vertically and fixedly connected to the base 1. The glue - applying frame 9 is a fixed structure. A rotating motor 11 is connected to the motor cover 10. The motor cover 10 can ensure the firm connection of the rotating motor 11. The output end of the rotating motor 11 is connected to a rotating pointer 35. The rotating pointer 35 is vertically connected to the output end of the rotating motor 11. A rotating column 34 is connected to the rotating pointer 35. The rotating column 34 is parallel to the output end of the rotating motor 11. A swing shaft 24 is connected to the glue - applying frame 9. A swing plate 25 is rotatably connected to the swing shaft 24. In the natural state, the swing plate 25 is in a vertical state, and the swing shaft 24 is connected to a position slightly above the middle of the swing plate 25 in the vertical state. A material cylinder 26 is connected to one side of the swing plate 25. A nozzle 33 is connected to the lower end of the swing plate 25. The material cylinder 26 is fixedly connected to the swing plate 25. The material cylinder 26 is connected to the nozzle 33 through a delivery pipe. A first cross bar 12 is slidably connected between the glue - applying frames 9. A pushing frame 20 is connected to the first cross bar 12. The rotating column 34 is slidably connected to the pushing frame 20. A return spring 22 is connected to the glue - applying frame 9. The other end of the return spring 22 is connected to the first cross bar 12. The return spring 22 is sleeved on the first cross bar 12. A placing table 7 is arranged on one side of the pushing frame 20. A placing groove 8 is opened on the placing table 7. A clamping piece 23 is connected to one side of the placing table 7. When applying glue, the clamping piece 23 is clamped on both sides of the pushing frame 20 and at the same time, the clamping piece 23 is clamped on the first cross bar 12. A transmission mechanism for driving the placing table 7 to move for glue - applying is arranged on one side of the placing table 7.

[0030] Specifically, as Figure 1 and Figure 5 shown, the transmission mechanism includes a cylinder 3. The cylinder 3 is vertically connected to the side plate 2. The placing table 7 is slidably connected to the output end of the cylinder 3. A rotating rod 6 is rotatably connected to the side plate 2. The output end of the rotating motor 11 is connected to a lower gear 19. An upper gear 16 is meshed and connected above the lower gear 19. A clamping groove 37 is opened on the upper gear 16. One end of the rotating rod 6 is connected to a convex strip 18. The structure of the rotating rod 6 with the convex strip 18 can just fit into the clamping groove 37. That is, when the convex strip 18 is clamped in the clamping groove 37, at this time, the rotation of the rotating rod 6 can drive the upper gear 16 to rotate. When the convex strip 18 is separated from the clamping groove 37, at this time, the rotation of the rotating rod 6 cannot drive the upper gear 16 to rotate.

[0031] Specifically, as Figure 3As shown in the figure, a bottom slide rail 27 is connected to the lower end of the placement table 7. A slider 28 is slidably connected to the bottom slide rail 27. A second cross bar 29 and a return spring 22 are connected to the slider 28. The slider 28 is fixedly connected to the output end of the air cylinder 3. Through the mutual sliding cooperation of the bottom slide rail 27 and the slider 28, the telescopic movement of the air cylinder 3 can drive the placement table 7 to move, and it does not interfere with the reciprocating movement of the placement table 7 in the direction perpendicular to the air cylinder 3.

[0032] Specifically, as Figure 3 shown in the figure, a first bevel gear 4 is rotatably connected to the side plate 2. A brush 5 is connected to the lower end of the first bevel gear 4. A second bevel gear 15 is connected to the rotating rod 6. When the air cylinder 3 contracts, the placement table 7 can be moved to below the brush 5. At this time, the first bevel gear 4 just meshes with the second bevel gear 15, and at this time, the brush 5 can be driven to rotate, completing the cleaning of the circuit board placed in the placement groove 8. The rotating structure can separate dust or impurities from the circuit board by centrifugal force. When the brush 5 approaches the circuit board, the brush 5 can also brush and clean the circuit board.

[0033] Specifically, as Figure 1 shown in the figure, a dial 17 is connected to the rotating rod 6. When the air cylinder 3 contracts, at this time, the convex strip 18 enters the card slot 37. When the rotating motor 11 rotates, it can drive the dial 17 to rotate. After moving, the dial 17 can also rotate the swing plate 25 by rotating. At this time, the cleaning operation of the circuit board surface is in progress. In this state, the swinging of the material cylinder 26 helps the internal pigment to be mixed evenly by oscillation.

[0034] Specifically, as Figure 1 and Figure 4 shown in the figure, a sliding frame 13 is connected to the upper end of the placement table 7. The placement table 7 and the sliding frame 13 are fixedly connected. When moving the placement table 7, the sliding frame 13 can be driven to move synchronously. The movement of the sliding frame 13 can synchronously drive the rotating rod 6 to move horizontally. The rotating rod 6 is slidably connected to the sliding frame 13. A clamping ring 30 is connected to the rotating rod 6. The clamping ring 30 clamps outside the sliding frame 13.

[0035] Specifically, as Figure 1 、 Figure 4 and Figure 6 shown in the figure, an elliptical frame 14 is slidably connected to one side of the sliding frame 13. A abutting spring 32 is connected to the rotating rod 6. Both ends of the abutting spring 32 are connected to an abutting wheel frame 31. The abutting wheel frame 31 abuts on the elliptical frame 14. A roller is rotatably connected to the abutting wheel frame 31. The reset of the rotating rod 6 structure can be completed by relying on the abutting wheel frame 31. During the rotation of the rotating rod 6, the roller at one end of the abutting wheel frame 31 makes rolling contact with the inner wall of the elliptical frame 14. When the rotating rod 6 resets, the dial 17 will only be in the vertically upward or vertically downward state.

[0036] Specifically, Figure 5 As shown, the motor cover 10 is connected with a collar 21, and a sleeve seat 36 is rotatably connected to the collar 21. The sleeve seat 36 is fixedly connected to the upper gear 16. The collar 21 can limit the upper gear 16 to ensure the stability of the rotation of the upper gear 16.

[0037] To sum up, the present embodiment provides an automatic gluing device for PCBA board assembly. When the circuit board needs to be glued, the operator only needs to place the circuit board on the placement table 7, and then the operator can remotely operate the cylinder 3 away from the equipment. A placement slot 8 is provided on the placement table 7. For circuit boards that do not match the placement slot 8, molds of different shapes can be placed on the placement slot 8, and then the circuit board can be placed on the mold to achieve the effect of gluing different types of circuit boards.

[0038] After the placement is completed, the operator starts the cylinder 3, which operates in the state of first contracting and then stopping for a period of time to clean the surface of the circuit board. Then the cylinder 3 extends, and then when the cylinder 3 stops for a period of time, glue is applied to the surface of the circuit board. When the cylinder 3 is running, the rotating motor 11 does not run. Only when the cylinder 3 stops extending and retracting, the rotating motor 11 will rotate.

[0039] When the cylinder 3 is retracted, the placement table 7 moves synchronously with the rotating rod 6. When the cylinder 3 is retracted to the maximum extent, the convex strip 18 is inserted into the slot 37, and the rotating motor 11 starts to rotate. When the rotating motor 11 rotates, it can drive the lower gear 19 and the upper gear 16 to rotate. At this time, the paddle 17 moves horizontally to the top of the swing plate 25, and the bevel gear 14 and the bevel gear 2 15 are meshed with each other. At this time, the rotation of the bevel gear 14 can drive the brush 5 to clean the upper surface of the circuit board. After the cleaning is completed, the cylinder 3 begins to extend, the rotating motor 11 stops rotating, and the cylinder 3 can push the placement table 7 to move to the nozzle 3 3, at this time, the clip 23 is clamped on the outside of the push frame 20, the convex strip 18 is separated from the slot 37, and the lower gear 19 rotates, while the rotating rod 6 does not rotate. The rotating motor 11 drives the rotating column 34 to rotate, thereby driving the push frame 20 to move back and forth, and synchronously driving the placement table 7 to move back and forth under the nozzle 33, and cooperating with the nozzle 33 to achieve gluing on the surface of the circuit board, wherein the timing of the barrel 26 transmitting the paint into the nozzle 33 is when the rotating motor 11 starts to rotate. When the rotating motor 11 completes the rotation, the circuit board completes the gluing operation, and each structure of the gluing device moves to the initial position.

[0040] The reset spring 22 can drive the placement table 7 and the push frame 20 to move to the middle position. The placement table 7 moves to the middle position to ensure that the clamping piece 23 can complete precise docking with the push frame 20. The push frame 20 moves to the initial position to complete docking with the clamping piece 23 and also ensure that the card slot 37 is just in a state of docking with the convex strip 18. The initial state of the convex strip 18 is reset by relying on the abutting wheel frame 31. The elliptical frame 14 itself is slidably connected to the sliding frame 13, and the abutting spring 32 is relied on to ensure that the abutting wheel frame 31 can abut against the longer diameter of the elliptical frame 14.

[0041] Through this glue coating device, the glue coating operation of the circuit board can be automatically completed. Each time the circuit board is placed, the operator can operate at a safe distance. The device can be optimized to realize the automatic placement of the circuit board through the mechanical structure, that is, the fully automatic glue coating operation of the circuit board can be realized, greatly improving the glue coating efficiency of the circuit board and also improving the glue coating quality of the circuit board, enabling the pigment to be evenly coated on the surface of the circuit board and reducing the labor intensity of the operator.

[0042] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
