[0038] Combination Figures 1 to 3 , a solar cell sheet screen wiping device, comprising:

[0039] The wiping mechanism 100 includes a frame 101, a winding roller 114 installed on one side of the frame 101, an unwinding roller 115 installed on the other side of the frame 101, and a support assembly provided between the winding roller 114 and the unwinding roller 115; the winding roller 114 is used to wind up the dust-free cloth 107, the unwinding roller 115 is used to unwind the dust-free cloth 107, and the support assembly is used to support the dust-free cloth 107;

[0040] The support assembly includes a slide mounting block 117 fixedly connected to the frame 101, a base 108 slidably connected to the slide mounting block 117, a pressing member 120 fixed to the base 108, and a mounting base 110 elastically connected to the base 108;

[0041] The moving mechanism 200 is connected to the wiping mechanism 100 and is used to move the wiping mechanism 100 to a designated position.

[0042] In this embodiment, the wiping mechanism 100 further includes a winding motor 104 connected to a winding roller 114, a gear 105 connected to an unwinding roller 115, and a rotary damper 106 meshed with the gear 105. The unwinding roller 115 is used to wind up a clean dust-free cloth 107, and the winding roller 114 is used to wind up a dirty dust-free cloth 107.

[0043] In this embodiment, if Figure 4 As shown, the winding roller 114 and the unwinding roller 115 are further provided with a tightening portion 122 . The tightening portion 122 may be a handle, so that the operator can rotate the tightening portion 122 and replace the dust-free cloth 107 conveniently.

[0044] In this embodiment, combined with Figures 4 to 6The support assembly also includes a cross roller slide 118 fixed to the side wall of the slide mounting block 117 and a second guide rail 119 slidably connected to the cross roller slide 118, and one side of the second guide rail 119 is fixedly connected to the side of the base 108.

[0045] In this embodiment, an elastic element 109 is provided between the base 108 and the mounting seat 110, one end of the elastic element 109 abuts against the base 108, and the other end of the elastic element 109 abuts against the mounting seat 110. Specifically, the base 108 includes a main base and a secondary base, the main base includes two first side plates arranged opposite to each other and two second side plates arranged opposite to each other, the first side plates and the second side plates are both fixed to the secondary base, and a connecting element such as a bolt can be used to sequentially pass through the first side plate and the pressing member 120 or sequentially pass through the second side plate and the pressing member 120 to achieve the connection between the main base and the pressing member 120, and this design also facilitates the subsequent replacement of the flexible cloth wrapped around the pressing member 120. Among them, the elastic element 109 can be a compression spring.

[0046] In this embodiment, the surface of the pressing member 120 facing the dust-free cloth 107 is wrapped with a flexible cloth. Specifically, the flexible cloth can be sheepskin, which is flexible and elastic, and reduces the friction between the dust-free cloth 107. It should be noted that if a sponge or other wiping material is used, when the wiping mechanism 100 has a constant height in the vertical direction, the pressing force on the central part of the screen 300 becomes smaller and the cleaning ability becomes weaker, so the dust-free cloth 107 is selected.

[0047] Furthermore, when the screen 300 is in a plane parallel to the horizontal plane, the screen 300 is easily deformed after being pressed, and the deformation of the central part of the screen 300 is greater than the deformation of the edge of the screen 300 when the same force is pressed. In addition, when the wiping pressure is too large, the screen 300 will be damaged.

[0048] In order to control the wiping force of the wiping mechanism 100, the wiping mechanism 100 also includes a measuring component arranged at the bottom of the mounting seat 110, and the measuring component includes a pressing block 111, a pressure sensor 112 and a first support block 113. The pressure sensor 112 is arranged between the pressing block 111 and the first support block 113, and the pressure sensor 112 is fixed on the first support block 113. It should be noted that when the pressing member 120 is pressed, the cross roller slide 118 will drive the base 108 to move downward, at which time the elastic element 109 will be pressed, and the pressing force is measured by the pressure sensor 112 through the pressing block 111, so the pressure sensor 112 is not fixedly connected to the pressing block 111.

[0049] In other possible embodiments, the wiping mechanism 100 also includes a first guide roller 116 disposed between the winding roller 114 and the base 108 and a second guide roller 121 disposed between the unwinding roller 115 and the base 108. The first guide roller 116 and the second guide roller 121 function to provide a fixed track or axis for the dust-free cloth 107 to ensure that the dust-free cloth 107 maintains the correct direction and position during movement.

[0050] In this embodiment, combined with Figure 1 and Figure 2 The moving mechanism 200 includes a mechanical arm 201 that can move up and down, an extension arm 202 connected to the free end of the mechanical arm 201, and a second support block 203 provided at one end of the extension arm 202; the second support block 203 is used to fix the frame 101 of the wiping mechanism 100. The second support block 203 is L-shaped and can support the wiping mechanism 100 from two directions.

[0051] Furthermore, a first slider 103 and a first guide rail 102 sliding along the first slider 103 are arranged between the second support block 203 and the frame 101. The first guide rail 102 is fixed to the back of the frame 101, and the first slider 103 is fixed to the second support block 203.

[0052] Combination Figure 1 and Figure 7 , the working principle of the utility model is as follows:

[0053] The battery cell is detected abnormally by the visual inspection device (not shown in the figure) on the platform 400, the printer stops printing, the screen 300 is lifted, the moving mechanism 200 drives the wiping mechanism 100 to move below the screen 300, and the screen 300 is wiped with a dust-free cloth 107, wherein the moving path of the moving mechanism 200 is as follows: Figure 7 In the direction indicated by the arrow, the screen 300 can be wiped clean.

[0054] The dust-free cloth 107 passes through the unwinding roller 115, the second guide roller 121, the upper surface of the pressing member 120 and the first guide roller 116 in sequence, and is finally wound on the winding roller 114. That is, one side of the dust-free cloth 107 is wound around the unwinding roller 115, and the other side of the dust-free cloth 107 is wound around the winding roller 114. The winding motor 104 is started, and the rotation of the winding motor 104 drives the winding roller 114 to rotate, thereby winding the dust-free cloth 107, and the dust-free cloth 107 on the unwinding roller 115 is passively rotated, and the dust-free cloth 107 is unwound. The unwinding roller 115 drives the rotary damper 106 to rotate through the gear 105, and under the action of the rotary damper 106, the dust-free cloth 107 will not loosen.

[0055] When the pressing member 120 contacts the screen 300 and is pressed, the cross-roller slide 118 will drive the base 108 to move downward. At this time, the elastic element 109 will be pressed, and the pressing force is measured by the pressure sensor 112, that is, the wiping pressing pressure of the wiping mechanism 100 is measured by the pressure sensor 112, and the wiping pressing pressure of the wiping mechanism 100 can be set.

[0056] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0057] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
