[0022] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the drawings, some commonly used structures and components are depicted in simplified schematic form.

[0023] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0024] This embodiment provides an automatic dispensing device for PCB boards. The automatic dispensing device for PCB boards realizes automated dispensing of PCB boards. Compared with traditional manual operation or semi-automatic dispensing operation, it greatly improves the dispensing efficiency of PCB boards, reduces manpower consumption, and can also effectively improve the dispensing quality of PCB boards.

[0025] Combine Figures 1 to 4 As shown, the PCB board automatic dispensing equipment of this embodiment includes a carrier board 10, a dispensing unit 20 and a driving unit. The carrier board 10 is provided with a receiving cavity 11 to accommodate the PCB board. Under the action of the driving unit, the dispensing unit 20 moves along the first direction, the second direction and the third direction respectively to perform dispensing on the PCB board located in the receiving cavity 11.

[0026] In this embodiment, the PCB board automatic dispensing equipment also includes a base plate 40, the carrier plate 10 and the driving part are all installed on the base plate 40, and a number of support seats 60 are provided on the base plate 40, and a guide rail 61 is provided on the support seat 60 to guide the dispensing part 20 to move along the first direction. With the cooperation of the guide rail 61, the dispensing part 20 is guided to move.

[0027] Combine Figure 1 and Figure 3As shown, the dispensing part 20 of this embodiment includes a bracket 21, a driving cylinder 22 and a dispensing head 23. The driving cylinder 22 is installed on the bracket 21. The dispensing head 23 is installed on the bracket 21 through a buffer spring 50, and the dispensing head 23 is driven by the driving cylinder 22. The presence of the buffer spring 50 can buffer the dispensing head 23 during the dispensing process of the dispensing head 23 to avoid hard contact between the dispensing head 23 and the PCB board. Under the driving action of the driving part, the dispensing part 20 can move in the first direction, the second direction and the third direction, and the driving cylinder 22 of the dispensing part 20 drives the dispensing head 23 to make the dispensing head 23 close to the PCB board for dispensing operation, thereby completing the automated dispensing process of the PCB board to improve the dispensing efficiency.

[0028] In this embodiment, a detection camera 70 is provided on the bracket 21, and the detection camera 70 moves synchronously with the bracket 21. Before dispensing glue on the PCB board, the detection camera 70 determines the glue dispensing position on the PCB board so that the subsequent glue dispensing unit 20 can dispense glue on the PCB board to improve the glue dispensing accuracy.

[0029] like Figure 1 As shown, the driving part includes a first module 31, a second module 32 and a third module 33, which respectively drive the dispensing part 20 to move along the first direction, the second direction and the third direction. The guide rail 61 is arranged parallel to the first module 31, and the bracket 21 is an L-shaped structure and is installed on the third module 33. The first module 31, the second module 32 and the third module 33 of this embodiment are all linear modules driven by servo motors, thereby realizing multi-directional movement of the dispensing part 20, and then realizing automated dispensing processing of the PCB board, improving dispensing efficiency, and ensuring dispensing accuracy.

[0030] In actual use, the PCB board automatic dispensing equipment of this embodiment places the PCB board in the accommodating cavity 11 of the carrier board 10, and the first module 31, the second module 32 and the third module 33 of the driving unit drive the dispensing unit 20, and the dispensing unit 20 performs a dispensing operation on the PCB board. Before the dispensing operation, the detection camera 70 detects and determines the dispensing position of the PCB board, and then performs the corresponding dispensing process. Therefore, it realizes the automatic dispensing process of the PCB board. Compared with the traditional manual operation or semi-automatic dispensing operation, it greatly improves the dispensing efficiency of the PCB board, reduces manpower consumption, and can also effectively improve the dispensing quality of the PCB board.
