[0032] The following further elaborates on the present utility model in conjunction with the attached Figures 1 to 3 drawings.

[0033] Referring to Figures 1 to 3 the figure shown, the circuit board cleaning device includes a frame 100, a driving component 200, and a cleaning component 300. A workbench 110 is provided in the middle of the frame 100, and a conveyor belt 111 is provided in the middle of the workbench 110. The conveyor belt 111 is used to convey the circuit board. The driving component 200 is arranged at the upper part of the frame 100 and above the workbench 110. The cleaning component 300 is also located above the workbench 110. The cleaning component 300 is connected to the driving component 200, and the driving component 200 can drive the cleaning component 300 to move in the up and down direction. The cleaning component 300 includes a roller 310 and a first connecting block 320. The first connecting block 320 is connected to the output end of the driving component 200 and can approach or move away from the workbench 110 under the drive of the driving component 200. There are two first connecting blocks 320. Bearings are provided on the first connecting blocks 320, and the roller 310 is rotatably arranged between the two first connecting blocks 320 through the bearings. An adhesive tape 330 is pasted on the circumferential outer surface of the roller 310. It can be understood that the cleaning component 300 is symmetrically arranged on both sides of the workbench 110 with the central axis of the workbench 110 as the axis of symmetry. The driving component 200 is connected to the cleaning component 300, so that the driving component 200 can drive the roller 310 to approach the workbench 110 to clean the circuit board in the middle of the workbench 110.

[0034] In the embodiment of the present utility model, a driving component 200 and a cleaning component 300 are arranged in the frame 100. The cleaning component 300 includes a roller 310 and a first connecting block 320. The first connecting block 320 is connected to the output end of the driving component 200. The roller 310 is rotatably arranged between two first connecting blocks 320 through bearings. Driven by the driving component 200, the first connecting block 320 can move closer to or away from the workbench 110, that is, the first connecting block 320 can move along the up-and-down direction. When the first connecting block 320 moves, the roller 310 moves together with the first connecting block 320. A sticker 330 is pasted on the circumferential outer surface of the roller 310. When the roller 310 follows the first connecting block 320 and descends to a certain height, the sticker 330 pasted on the circumferential outer surface of the roller 310 abuts against the surface of the circuit board above the conveyor belt 111 of the workbench 110. The sticker 330 adheres to dirt such as dust, fiber filaments, and oil stains on the surface of the circuit board, thereby improving the cleanliness of the circuit board. The whole process does not require manual operation and can also improve the cleaning efficiency of the circuit board.

[0035] It can be understood that, referring to Figure 1 and Figure 2 As shown, in the embodiment of the present utility model, the driving component 200 includes a first driver 210 and a second connecting block 220. A top plate 120 is provided above the frame 100. The fixed end of the first driver 210 is fixed to the top plate 120. The output end of the first driver 210 passes through the top plate 120 and extends downward. The first driver 210 can be a motor or a cylinder. There are two first drivers 210. The two first drivers 210 are symmetrically arranged on both sides of the workbench 110 with the central axis of the top plate 120 as the axis of symmetry. The output ends of the two first drivers 210 are connected to the second connecting block 220, and the second connecting block 220 is connected to the first connecting block 320, thereby driving the first connecting block 320 to move.

[0036] It can be understood that, referring to Figure 1 and Figure 2 As shown, in the embodiment of the present utility model, guide rods 230 are penetrated through the left and right sides of the second connecting block 220. One end of the guide rod 230 is connected to the bottom of the top plate 120 of the frame 100, and the other end is connected to the connecting block. The guide rod 230 extends in the vertical direction and can be extended or shortened. The guide rod 230 can provide a guiding function when the first driver 210 drives the cleaning component 300 to move in the up-and-down direction, improve the accuracy of the cleaning component 300 in the up-and-down direction, enable the roller 310 to be aligned with the circuit board above the workbench 110, and further perform the cleaning work on the circuit board.

[0037] Referring to Figures 1 to 3As shown, in an embodiment of the present utility model, the cleaning assembly 300 also includes an elastic member 340, a mounting plate 350 and a contour screw 360. The mounting plate 350 is connected to one end of the guide rod 230 away from the top plate 120 of the frame 100. The contour screw 360 is penetrated through the mounting plate 350, and the fixed end of the contour screw 360 is located above the mounting plate 350. The connecting end of the contour screw 360 passes through the elastic member 340 and is connected to the first connecting block 320. The elastic member 340 is a compression spring. The roller 310 is rotatably arranged between the two first connecting blocks 320. The elastic member 340 can enable the roller 310 to move up and down when it abuts against the circuit board, so that there is a buffer when the roller 310 contacts the circuit board, reducing the impact force of the roller 310 on the circuit board when it descends, reducing damage to the surface of the circuit board, and improving the production quality of the circuit board. In addition, the roller 310 can also clean circuit boards of different thicknesses.

[0038] It is understandable that, referring to Figure 1 As shown, in the embodiment of the utility model, the circuit board cleaning device further includes a limiting mechanism 400, and the limiting mechanism 400 includes a fixing plate 410, a second driver 420 and a limiting plate 430. The fixing plate 410 is vertically fixed to one side of the workbench 110 of the frame 100, the fixing plate 410 is provided with a mounting hole, the second driver 420 is penetrated through the mounting hole, and the limiting plate 430 is arranged at the output end of the second driver 420, the output end of the second driver 420 faces one side of the conveyor belt 111 of the workbench 110, and the limiting plate 430 can approach or move away from the conveyor belt 111 under the drive of the second driver 420, so that the limiting plate 430 abuts against the side wall of the circuit board to limit the circuit board.

[0039] Reference Figure 1 As shown, in an embodiment of the utility model, the limiting mechanism 400 is symmetrically arranged on both sides of the workbench 110, and the two limiting plates 430 are arranged opposite to each other, that is, the two limiting plates 430 are symmetrically arranged on both sides of the workbench 110, and the two limiting plates 430 are arranged opposite to each other. It can be understood that the two limiting plates 430 are arranged to abut against the side walls on both sides of the circuit board at the same time, thereby limiting the left and right directions of the circuit board, reducing the possibility of the circuit board deviating from the conveyor belt 111.

[0040] It is understandable that, referring to Figure 1 As shown, in an embodiment of the present utility model, a buffer layer is provided on the side of the limit plate 430 facing the workbench 110, that is, a buffer layer is provided on the opposite side of the two limit plates 430, and the buffer layer is made of rubber material. The buffer layer can effectively reduce the damage to the outer wall of the circuit board when it abuts against the limit plate 430, thereby improving the production quality of the circuit board.

[0041] It is understandable that, referring to Figure 1As shown, in the embodiment of the present utility model, the length of the roller 310 is less than the distance between the two side limiting mechanisms 400. If the length of the roller 310 is greater than the distance between the two side limiting mechanisms 400 on both sides of the workbench 110 of the frame 100, when the first driver 210 drives the roller 310 to descend, the roller 310 will interfere with the limiting plate 430, damaging the structure of the roller 310 or the limiting plate 430. Therefore, it is defined that the length of the roller 310 is less than the distance between the two side limiting mechanisms 400, so that the roller 310 can smoothly clean the surface of the circuit board.

[0042] It should be noted that, in some embodiments, a guide rail is provided on the upper surface of the workbench 110. The guide rail extends along the length direction of the workbench 110, that is, the guide rail extends along the left-right direction. A slider is provided at the bottom of the limiting plate 430, and the limiting plate 430 is slidably connected to the guide rail through the slider. The guide rail can provide high linear accuracy for the limiting plate 430, reduce the deviation angle during the movement of the limiting plate 430, and can limit the circuit board.

[0043] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
