[0025] The utility model is described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 3 As shown, the utility model is a surface cleaning mechanism for PCB board production, comprising a working chamber 1, a frame 2 arranged in the working chamber 1, a conveyor belt 3 rotatably arranged on the frame 2 and used to transport the PCB board to be cleaned, and a cleaning component 4 arranged in the working chamber 1, the frame 2 is arranged through both sides of the working chamber 1, the cleaning component 4 comprises a lifting seat 41, a driving cylinder 42 for driving the lifting seat 41 to rise and fall, a cleaning roller 43 arranged on the lifting seat 41, and a driving motor 44 for driving the cleaning roller 43 to rotate, the driving cylinder 42 drives the cleaning roller 43 to approach or move away from the conveyor belt 3 through the lifting seat 41, so that the driving motor 44 drives the cleaning roller 43 to rotate and roll clean the PCB board to be cleaned placed on the conveyor belt 3.

[0027] When working, firstly, the PCB board to be cleaned is transported toward the working chamber 1 through the conveyor belt 3, so that the PCB board to be cleaned is placed horizontally on the conveyor belt 3 to avoid scratches and wear. When the conveyor belt 3 transfers the PCB board to be cleaned into the working chamber 1, the conveyor belt 3 stops working, and then the driving cylinder 42 drives the cleaning roller 43 to move downward and close to the conveyor belt 3 through the lifting seat 41, so that the driving motor 44 drives the cleaning roller 43 to rotate and roll the PCB board to be cleaned placed on the conveyor belt 3 to clean automatically. The dust and debris on the PCB board are removed and cleaned, and finally the conveyor belt 3 is started again to transfer the cleaned PCB board out of the working chamber 1. The utility model realizes the automatic cleaning of the PCB board, reduces the labor cost, is simple and convenient to operate, improves the cleanliness and cleaning efficiency of the PCB board, and ensures the product quality of the PCB board.

[0028] The cleaning roller 43 of this embodiment includes a roller body 431, a dust-sticking layer 432 sleeved on the outside of the roller body 431, and a peeling layer 433 wound on the outside of the dust-sticking layer 432, the dust-sticking layer 432 is provided with multiple and multiple dust-sticking layers 432 are provided with a first easy-tear line 434, the peeling layer 433 is provided with multiple and multiple peeling layers 433 are provided with a second easy-tear line 435, and each first easy-tear line 434 is staggered with each second easy-tear line 435. Specifically, before work, the peeling layer 433 is torn off along the second tear line 435, so that the sticky layer 432 is exposed. When the driving motor 44 drives the cleaning roller 43 to rotate, the rotating roller body 431 uses the sticky layer 432 to efficiently stick and take away the dust and debris on the surface of the PCB board. Since the sticky layer 432 will lose its stickiness after multiple cleaning uses, it is easy for the originally adhered dust and debris to accidentally fall onto the subsequent PCB board, resulting in a significant reduction in the subsequent cleaning effect. If the entire cleaning roller 43 is replaced, the operation is cumbersome and time-consuming, which increases production costs and reduces production efficiency. Therefore, it is only necessary to tear off the dust-adhered layer 432 along the first tear line 434. The sticky layer 432 of the debris is torn off, and then the peeling layer 433 of the next layer is torn off along the second tearing line 435, so that the sticky layer 432 of the next layer is exposed, so that the cleaning roller 43 can continue to be used, and there is no need to replace the entire cleaning roller 43, which can better save costs. In addition, each first tearing line 434 and each second tearing line 435 are staggered, which effectively avoids accidentally tearing off all the peeling layers 433 and the sticky layer 432 due to excessive force. The first tearing line 434 and the second tearing line 435 are simple and convenient to use, and can be torn off with just a slight pull, without the need to use additional tools such as knives, which can reduce misoperation and improve work safety. Among them, the material of the peeling layer 433 is the release paper of the prior art, which is easy to peel off and has good protective performance. The material of the sticky layer 432 is nano resin, which not only has good dust removal viscosity, but also has good antistatic performance to avoid static electricity from damaging the PCB board.

[0029] The cleaning assembly 4 of this embodiment further includes a mounting seat 45 disposed on the inner side wall of the working chamber 1, the mounting seat 45 is provided with a guide rod 46, and the lifting seat 41 is provided with a guide sleeve 47 slidably connected to the guide rod 46. Specifically, as a preferred embodiment, two guide rods 46 are provided and spaced apart on the mounting seat 45, the two guide rods 46 are fixed to the inner side wall of the working chamber 1 by the mounting seat 45, two guide sleeves 47 are provided and spaced apart on the lifting seat 41, and the lifting seat 41 slides up and down along the guide rod 46 through the guide sleeves 47, thereby playing a good guiding and supporting role.

[0030] The working chamber 1 of this embodiment is provided with a through slot 11 on one side close to the cleaning assembly 4, and the driving motor 44 is connected to the lifting seat 41 so that the driving motor 44 passes through the through slot 11 and protrudes out of the working chamber 1. A sealing door 12 is hinged on the outside of the working chamber 1, and a door handle 13 is provided on one side of the sealing door 12, and the sealing door 12 is provided with a tempered glass 14. Specifically, the operator opens or closes the sealing door 12 through the door handle 13, and the sealing door 12 can close and seal the working chamber 1, effectively preventing dust and debris from the outside from entering the working chamber 1 through the through slot 11. The driving motor 44 passes through the through slot 11 and protrudes out of the working chamber 1. The driving motor 44 is provided on the lifting seat 41 and moves up and down along the through slot 11 with the lifting seat 41. The operator can clearly observe the working condition of the driving motor 44 through the tempered glass 14 without opening the sealing door 12.

[0031] The top of the working chamber 1 of this embodiment is provided with a control button 15, and the bottom of the working chamber 1 is provided with a fixing frame 16. Specifically, a plurality of control buttons 15 are provided on the top of the working chamber 1, and the working conditions of the working parts such as the conveyor belt 3, the driving cylinder 42, and the driving motor 44 are intelligently controlled by pressing corresponding control buttons 15.
