[0031] See also Figures 1 to 4 The present embodiment provides a fully automatic non-contact electrostatic dust removal device, including a frame 1 and a PCB transmission track 2, an electrostatic dust removal mechanism 3, and a dust collecting mechanism 4 arranged on the frame 1. The PCB transmission track 2 is used to receive the PCB board output from the previous process (such as a board separator), and to transmit the PCB board after electrostatic dust removal to the next process. The electrostatic dust removal mechanism 3 is used to perform comprehensive electrostatic dust removal on the surface of the PCB board on the PCB transmission track 2. The dust collecting mechanism 4 is arranged directly above the PCB transmission track 2. After the dust collecting mechanism 4 is started, the dust blown away by the electrostatic dust removal mechanism 3 can be collected synchronously.

[0032] The electrostatic dust removal mechanism 3 includes an electrostatic dust removal module 31 for removing dust and static electricity on the PCB board and a translation module 32 for driving the electrostatic dust removal module 31 to move forward and backward along the transmission direction of the PCB board. The translation module 32 is connected to the frame 1, and the electrostatic dust removal module 31 is connected to the movable end of the translation module 32 and is located above the PCB transmission track 2. After the PCB transmission track 2 receives the PCB board, the translation module 32 is started to drive the electrostatic dust removal module 31 to move forward and backward along the transmission direction of the PCB board. The electrostatic dust removal module 31 is started while moving, wherein the translation module 32 drives the electrostatic dust removal module 31 to pass through the PCB board at least once forward and backward, thereby achieving comprehensive electrostatic dust removal on the surface of the PCB board. This forward and backward movement ensures the uniformity and comprehensiveness of cleaning and avoids dead corners or omissions.

[0033] See also Figure 2 , Figure 3 In one embodiment, the electrostatic dust removal module 31 includes a wind knife assembly 311 and an ion wind rod assembly 312 which are arranged obliquely downward. The wind knife assembly 311 is connected to the movable end of the translation module 32, and the ion wind rod assembly 312 is connected to the side of the wind knife assembly 311 away from the translation module 32. The ion wind rod assembly 312 is used to blow ion wind toward the surface of the PCB board to eliminate the static electricity of the PCB board and make it difficult for dust to adhere to the surface of the PCB board. The wind knife assembly 311 uses the fluid Coanda effect (wall effect) to create an invisible uniform airflow, impact the surface of the PCB board, and lift the dust on the PCB board to be sucked away and collected by the dust collection mechanism 4. Among them, the uniform airflow is generated by compressed air entering the internal air knife high-pressure chamber through the air inlet of the wind knife assembly 311, and then passing through the narrow and thin air gap to form a large flow, strong impact, low air consumption, low noise and uniform flow airflow in the length direction of the air knife.

[0034] Specifically, the translation module 32 includes two first conveyor belts 321 respectively arranged on both sides of the PCB transmission track 2 and two first linear guide rails 322 respectively arranged on both sides of the PCB transmission track 2. The two sides of the electrostatic dust removal module 31 are respectively connected to the two first conveyor belts 321 through a connecting frame 323, and the two sides of the electrostatic dust removal module 31 are respectively slidably connected to the two first linear guide rails 322 through a connecting frame 323. After the two first conveyor belts 321 are started synchronously, the electrostatic dust removal module 31 can be smoothly driven to move forward and backward along the two first linear guide rails 322 through the connecting frame 323. The translation module 32 adopts the transmission mode of the conveyor belt and the linear guide rail. Compared with other transmission modes, it has higher stability and reliability, ensures the continuity of the electrostatic dust removal process, and improves production efficiency.

[0035] See also Figure 3 In one embodiment, guide limit strips 21 are provided on both sides of the PCB transmission track 2, and the spacing between the two guide limit strips 21 matches the width of the PCB board. The provision of the guide limit strips 21 ensures that the PCB board can be stably and accurately positioned on the track during the transmission process without deviation or shaking.

[0036] See also Figure 3 In one embodiment, the PCB transmission track 2 includes a fixed rail 22 and a movable rail 23 that are relatively arranged. The fixed rail 22 is fixedly connected to the frame 1, and the movable rail 23 is movably connected to the frame 1. The movable rail 23 can be close to or away from the fixed rail 22. Since the movable rail 23 can be close to or away from the fixed rail 22, the PCB transmission track 2 can adjust the distance between the movable rail 23 and the fixed rail 22 according to the size of different PCB boards, so that the device can adapt to a variety of PCB boards of different specifications, thereby improving the compatibility and application range of the device. By adjusting the position of the movable rail 23, PCB boards of different widths can be easily adapted without replacing the entire transmission track or performing complex adjustment operations. This not only reduces production preparation time, but also improves production efficiency.

[0037] It should be noted that, in addition to directly transmitting PCB boards, the PCB transmission track 2 is also suitable for transmitting a carrier carrying PCB boards.

[0038] See also Figure 1 , Figure 4In one embodiment, a dustproof cover 5 is provided on the frame 1, and the dustproof cover 5 covers the PCB transmission track 2, the electrostatic dust removal mechanism 3, and the dust collection mechanism 4 to prevent external dust from entering the interior of the device, and provide a dust-free environment for the electrostatic dust blowing operation of the PCB board. Among them, the front and rear sides of the dustproof cover 5 are respectively provided with a board inlet 51 and a board outlet 52, and the positions of the board inlet 51 and the board outlet 52 correspond to the position of the PCB transmission track 2. The setting of the board inlet 51 and the board outlet 52 allows the PCB board to smoothly enter and leave the dustproof cover 5, while minimizing the possibility of dust entering, thereby ensuring the efficient implementation of the electrostatic dust removal operation.

[0039] See also Figure 2 , Figure 3 In one embodiment, a first closing mechanism 6 for closing the board inlet 51 and a second closing mechanism 7 for closing the board outlet 52 are provided on the frame 1, and the first closing mechanism 6 and the second closing mechanism 7 are respectively arranged on the front and rear sides of the PCB transmission track 2. When the board is fed in, the first closing mechanism 6 opens the board inlet 51 so that the PCB transmission track 2 can smoothly receive the PCB board output from the previous process. During the electrostatic dust removal operation, the first closing mechanism 6 closes the board inlet 51 and the second closing mechanism 7 closes the board outlet 52 to prevent the dust blown away by the electrostatic dust removal mechanism 3 from escaping to the outside, thereby ensuring a dust-free working environment. A dust-free environment is essential for the electrostatic dust removal operation, as it can prevent dust from adhering to the PCB board again, thereby improving the cleaning effect. When the board is discharged, the second closing mechanism 7 opens the board outlet 52 so that the PCB transmission track 2 can smoothly transfer the PCB board to the next process.

[0040] Specifically, the first closing mechanism 6 includes a first lifting cylinder 61 and a first closing plate 62. The first lifting cylinder 61 is arranged at the lower front side of the PCB transmission track 2 and connected to the frame 1. The lifting end of the first lifting cylinder 61 is connected to the first closing plate 62 to drive the first closing plate 62 to open / close the board entry 51. When the first lifting cylinder 61 extends the first closing plate 62 to the position of the board entry 51, the board entry 51 is closed; when the first lifting cylinder 61 retracts the first closing plate 62 to the lower side of the PCB transmission track 2, the board entry 51 is opened, so that the PCB transmission track 2 can smoothly receive the PCB board output from the previous process.

[0041] Specifically, the second closing mechanism 7 includes a second lifting cylinder 71 and a second closing plate 72. The second lifting cylinder 71 is arranged at the rear lower part of the PCB transmission track 2 and connected to the frame 1. The lifting end of the second lifting cylinder 71 is connected to the second closing plate 72 to drive the second closing plate 72 to open / close the board outlet 52. When the second lifting cylinder 71 extends the second closing plate 72 to the position of the board outlet 52, the board outlet 52 is closed; when the second lifting cylinder 71 retracts the second closing plate 72 to the lower part of the PCB transmission track 2, the board outlet 52 is opened, so that the PCB transmission track 2 can smoothly transfer the PCB board to the next process.

[0042] In one embodiment, the dustproof cover 5 and the frame 1 are both made of stainless steel. Since stainless steel has a smooth surface and good anti-adhesion performance, it is difficult for dust to adhere to the surface of the dustproof cover 5 and the frame 1. This helps to keep the equipment clean, reduce dust pollution and damage to the internal components of the equipment, and extend the service life of the equipment.

[0043] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0044] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
