[0002] The dispensing process is an important means to protect circuit boards. By pre-applying a kind of glue for fixing patch components at the positions on the circuit board where patches need to be placed, it can make electronic products have better functions such as adhesion, potting, insulation, fixation, and smooth surface. Currently, the dispensing method for circuit boards generally uses manual holding of a syringe for dispensing. However, manual dispensing not only has low work efficiency and poor dispensing quality, but also some use robotic arms for dispensing. However, the cost of robotic arms is relatively high, and due to the height of components on the circuit board, the robotic arm cannot control the syringe to move to the bottom of the component for dispensing, thus unable to achieve dispensing at every position on the circuit board.

[0031] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0032] This embodiment relates to a universal dispensing device for circuit boards. In terms of the overall structure, as Figure 1 shown, it includes a column 1, a transverse sliding mechanism 3, a longitudinal sliding mechanism 4, a rotating mechanism 5, and a syringe 6.

[0033] Among them, the number of columns 1 is two. A cross beam 2 is horizontally arranged across the tops of the two columns 1. A transverse sliding mechanism 3 is fixedly arranged on the cross beam 2. A longitudinal sliding mechanism 4 moves along with the transverse sliding mechanism 3. A rotating mechanism 5 moves along with the longitudinal sliding mechanism 4. A syringe 6 moves along with the rotating mechanism 5 to apply glue at different positions of the circuit board.

[0034] It is worth mentioning that the cross beam 2 is horizontally arranged, and the two columns 1 are located at both ends of the cross beam 2. The circuit board is placed between the two columns 1. Such an arrangement ensures that the syringe 6 can lift and move within the cross beam 2 and the columns 1, facilitating the application of glue to the circuit board. The columns 1 can be installed on the workbench, and a sliding device is installed on the workbench. The sliding device drives the circuit board to reciprocate. The transverse sliding mechanism 3 can drive the syringe 6 to move horizontally, and the longitudinal sliding mechanism 4 can drive the syringe 6 to lift, thereby realizing glue application. The transverse sliding mechanism 3 cooperates with the sliding device on the workbench. This sliding device is a common linear sliding device, so its specific structure is not mentioned. It can apply glue to each position of the circuit board. The rotating mechanism 5 can drive the syringe 6 to rotate, which can expand the glue application area of the syringe 6 and improve the convenience of glue application.

[0035] Based on the above overall introduction, an exemplary structure of the universal glue application device for the circuit board in this embodiment is as Figure 2 shown. The transverse sliding mechanism 3 includes a housing 301 fixedly arranged on the cross beam 2, a lead screw 302 rotatably arranged on the housing 301, and a flange 303 screwed on the lead screw 302. A bearing plate 304 is fixedly arranged on the flange 303. Through grooves 305 are formed on both sides of the housing 301, and the bearing plate 304 extends out of the through grooves 305.

[0036] It should be noted that the housing 301 is horizontally installed on the cross beam 2. The lead screw 302 is rotationally connected to the wall of the housing 301 horizontally. One end of the lead screw 302 extending out of the housing 301 is connected to a stepping motor to drive the rotation of the lead screw 302. Since the lead screw 302 and the flange 303 are screwed together, it can drive the flange 303 to move. The bearing plate 304 is fixedly installed on the flange 303, thereby driving the bearing plate 304 to move. After the bearing plate 304 extends out of the through groove 305, it is fixedly connected to the longitudinal sliding mechanism 4, and can drive the longitudinal sliding mechanism 4 to move, thereby realizing the reciprocating sliding of the longitudinal sliding mechanism 4, the rotating mechanism 5 and the syringe 6.

[0037] As a preference, still as Figure 2 shown, a slide rail 306 parallel to the lead screw 302 is arranged in the housing 301 of this embodiment. A slider 307 is fixedly arranged on the bearing plate 304, and the slider 307 is slidably arranged on the slide rail 306. Specifically, slide rails 306 can be respectively arranged on both sides of the lead screw 302. The slide rails 306 are parallel to the lead screw 302 to ensure that the moving directions of the slider 307 and the flange 303 are the same. The slider 307 is fixedly connected to the bearing plate 304 to ensure the stability of the bearing plate 304 during sliding.

[0038] Preferably, as Figure 1 and Figure 2 shown, the longitudinal sliding mechanism 4 and the transverse sliding mechanism 3 of this embodiment have the same structure. The housing 301 of the longitudinal sliding mechanism 4 is fixedly arranged on the bearing plate 304 of the transverse sliding mechanism 3, and the rotating mechanism 5 is fixedly arranged on the bearing plate 304 of the longitudinal sliding mechanism 4.

[0039] Specifically, the transverse sliding mechanism 3 drives the longitudinal sliding mechanism 4 to reciprocate horizontally, and the longitudinal sliding mechanism 4 drives the rotating mechanism 5 to reciprocate vertically. That is to say, the transverse sliding mechanism 3 and the longitudinal sliding mechanism 4 cooperate to drive the syringe 6 to perform cross-sliding. The sliding device on the workbench drives the circuit board to slide between the two columns 1, so as to realize three-dimensional movement and ensure that the syringe 6 can apply glue to any position of the circuit board.

[0040] As a preferred embodiment, as Figure 3 shown, in this embodiment, the rotating mechanism 5 includes a mounting plate 501 fixedly arranged on the bearing plate 304 of the longitudinal sliding mechanism 4, a driving motor 502 fixedly arranged on the mounting plate 501, and a roller shaft 503 rotatably arranged on the mounting plate 501. The syringe 6 is rotatably arranged at the bottom end of the roller shaft 503, and the driving end of the driving motor 502 is fixedly connected to the roller shaft 503.

[0041] It should be noted that a vertical plate extends outward from the bearing plate 304 of the longitudinal sliding mechanism 4, and the mounting plate 501 is fixedly installed horizontally on the vertical plate. The driving motor 502 is located at the upper part of the mounting plate 501. The driving shaft of the driving motor 502 is key-connected to the roller shaft 503. The roller shaft 503 passes through the mounting plate 501. The syringe 6 is installed on one side of the bottom of the roller shaft 503. When the driving motor 502 drives the roller shaft 503 to rotate, the syringe 6 rotates accordingly, thereby increasing the area of glue application and also improving the flexibility during glue application.

[0042] Preferably, as Figure 4 shown, a circular sleeve 504 is fixedly arranged at the bottom of the mounting plate 501 of this embodiment, and a bearing 505 is installed between the roller shaft 503 and the circular sleeve 504. Specifically, the circular sleeve 504 and the driving shaft of the driving motor 502 are coaxially arranged. The roller shaft 503 is inserted into the circular sleeve 504. This setting can improve the stability of the roller shaft 503 during rotation and also improve the strength of the roller shaft 503 during rotation, avoiding the roller shaft 503 and the syringe 6 flying out due to excessive centrifugal force. A bearing 505 is sleeved between the circular sleeve 504 and the roller shaft 503. The bearing 505 can assist the rotation of the roller shaft 503 and avoid excessive friction between the roller shaft 503 and the circular sleeve 504, thereby causing damage to the roller shaft 503.

[0043] As a preferred embodiment, as Figure 5As shown, in this embodiment, an installation frame 7 is fixedly arranged on the syringe 6, a connecting block 8 is fixedly arranged on the back of the installation, through holes 9 are respectively formed in the side surface of the roller shaft 503 and the connecting block 8, a bolt 10 is inserted into the through hole 9, and a nut 11 is screwed on the bolt 10.

[0044] It should be noted that the syringe 6 is fixedly installed on the installation frame 7, the connecting block 8 is in contact with the side surface of the roller shaft 503. Such a setting ensures that the syringe 6 is located on one side of the roller shaft 503. The connecting block 8 is fixed on the roller shaft 503 through the bolt 10 and the nut 11. The bolt 10 is inserted into the through holes 9 of the connecting block 8 and the roller shaft 503. The bolt 10 and the nut 11 can clamp the connecting block 8 and the roller shaft 503. When the nut 11 is loosened from the bolt 10, the connecting block 8 and the roller shaft 503 become loose, and the installation frame 7 can adjust the angle. Then, the nut 11 is tightened to fix the connecting block 8 and the roller shaft 503, so as to realize the adjustable angle of the syringe 6, and further realize the dispensing at the included angle between the component and the circuit board, thus ensuring that the dispensing can be carried out at any position of the circuit board.

[0045] In the circuit board universal dispensing device of this embodiment, through the setting of the horizontal sliding mechanism 3, it is ensured that the syringe 6 can move arbitrarily horizontally along the circuit board. Through the setting of the vertical sliding mechanism 4, it is ensured that the syringe 6 can rise after dispensing to avoid interference between the syringe 6 and the components on the circuit board. Through the setting of the rotating mechanism 5, it is ensured that the syringe 6 can rotate in all directions to increase the dispensing range of the circuit board. Through the cooperative setting of the connecting block 8 and the roller shaft 503, it is ensured that the angle of the syringe 6 can be adjusted to realize the dispensing at the included angle between the circuit board component and the circuit board.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
