[0002] A solar cell is a semiconductor device that converts solar energy into electrical energy. Currently, the most commonly used solar cells are crystalline silicon solar cells. The actual production process for crystalline silicon solar cells typically involves coating a crystalline silicon substrate with a thin film and performing post-coating. This post-coating process typically includes light injection, which can effectively increase the conversion efficiency of the solar cell. Light injection typically requires the use of a lamp to illuminate the surface of the solar cell. In the lamps required for light injection, the light source is typically housed in a lampshade to protect it. Dust and other stains gradually accumulate on the surface of the lampshade, affecting the intensity of the light and, in turn, the light injection effect of the solar cell.

[0027] The utility model provides a self-cleaning light injection lampshade, which includes a lampshade shell and a cleaning mechanism. The lampshade shell has a light emitting surface to be cleaned, and the cleaning mechanism includes a surface cleaning member and a cleaning driving member. The cleaning driving member is used to drive the surface cleaning member, and the cleaning driving member can drive the surface cleaning member to contact the light emitting surface and translate along the light emitting surface.

[0028] The self-cleaning light injection lampshade of the present invention includes a lampshade shell and a cleaning mechanism, wherein the lampshade shell has a light initial surface to be cleaned, and the cleaning mechanism includes a surface cleaning member and a cleaning driving member, the cleaning driving member is used to drive the surface cleaning member, and the cleaning driving member can drive the surface cleaning member to contact the light emitting surface and translate along the light emitting surface. Under the drive of the cleaning driving member, the surface cleaning member can contact the light emitting surface and translate, thereby achieving the effect of removing stains attached to the light emitting surface. And the surface cleaning member can clean the surface of the light emitting surface under the drive of the cleaning driving member, so there is no need for the operator to disassemble the lampshade shell. The surface cleaning member can clean the lampshade shell in the interval of the light injection process, so there is no need to stop the light injection equipment, and the risk of injury to the operator can be effectively reduced.

[0029] Figure 1 This is a structural diagram of a light injection lampshade according to the present invention. Figure 1 As shown, the self-cleaning light injection lampshade includes a lampshade shell 100 and a cleaning mechanism, wherein the lampshade shell 100 has a light emitting surface 110 to be cleaned, and the cleaning mechanism includes a surface cleaning member 210 and a cleaning driving member 220, wherein the cleaning driving member 220 is used to drive the surface cleaning member 210, and the cleaning driving member 220 can drive the surface cleaning member 210 to contact the light emitting surface 110 and translate along the light emitting surface 110.

[0030] It is understood that the surface cleaning member 210 can be driven by the cleaning drive member 220 to move in contact with the light emitting surface 110, which is equivalent to the surface cleaning member 210 wiping the light emitting surface 110. In actual use, the surface cleaning member 210 can perform a unidirectional translational motion while in contact with the light emitting surface 110 to prevent stains attached to the surface cleaning member 210 from being re-coated on the light emitting surface 110.

[0031] Reference Figure 1 As shown, in some examples of this embodiment, the lampshade housing 100 has a shielding surface 120 opposite to the light emitting surface 110, the cleaning drive member 220 is arranged on the side of the shielding surface 120 away from the light emitting surface 110, the surface cleaning member 210 is arranged on the side of the light emitting surface 110 away from the shielding surface 120, and the cleaning mechanism further includes a connecting member 230, the two ends of the connecting member 230 are respectively connected to the surface cleaning member 210 and the cleaning drive member 220. For example, according to Figure 1In the orientation shown in FIG, the shielding surface 120 is located above the light exit surface 110, and the cleaning drive member 220 can be disposed above the shielding surface 120, while the surface cleaning member 210 can be disposed below the light exit surface 110. By disposing the cleaning drive member 220 above the shielding surface 120, the space above the lampshade housing 100 can be effectively utilized, and the additional cleaning drive member 220 will not block the light emitted from the light exit surface 110, thereby avoiding the influence of the cleaning drive member 220 on the light injection process.

[0032] Reference Figure 1 As shown, in some examples of this embodiment, the cleaning drive member 220 includes a drive motor 221 and a transmission belt 222. The drive motor 221 is used to drive the transmission belt 222 to move. The transmission belt 222 is connected to the connecting member 230 and is used to drive the surface cleaning member 210 to move. It can be understood that the transmission belt 222 can be mounted on one or more pulleys, and the drive motor 221 can drive the pulley to rotate, and the transmission belt 222 is driven by the pulley to reciprocate. And, referring to Figure 1 The transmission belt 222 generally has a portion located above the pulley and a portion located below the pulley. There is a height difference between the transmission belt 222 located below the pulley and the transmission belt 222 located above the pulley. This allows the surface cleaning member 210 to automatically separate from the light exit surface 110 as it reciprocates with the transmission belt 222. For example, when the surface cleaning member 210 moves to a position above the pulley, the surface cleaning member 210 can contact the light exit surface 110 and translate along the light exit surface 110. During this process, the surface cleaning member 210 effectively wipes away stains on the light exit surface 110. When the surface cleaning member 210 moves to a position below the pulley, the surface cleaning member 210 is spaced apart from the light exit surface 110 and translates in the opposite direction. As a result, stains absorbed by the surface of the surface cleaning member 210 due to wiping will not be re-applied to the light exit surface 110. Therefore, by providing the transmission belt 222 in the cleaning drive member 220 , it is possible to avoid contamination caused by reverse translation while cleaning the light emitting surface 110 , thereby improving the cleaning efficiency.

[0033] Reference Figure 1 As shown, in some examples of this embodiment, the cleaning drive member 220 includes two transmission belts 222, which are arranged in parallel and are respectively arranged on both sides of the shielding surface 120. In addition, the cleaning mechanism includes two connecting members 230, which are respectively connected to the two transmission belts 222, and both of the connecting members 230 are connected to the surface cleaning member 210. Figure 1In the illustrated position, two transmission belts 222 are respectively disposed on the front and rear sides of the shielding surface 120, and two connecting members 230 are also respectively disposed on the front and rear sides of the shielding surface 120. By providing two transmission belts 222 and two connecting members 230, the surface cleaning member 210 can achieve more complete contact with the light emitting surface 110 during translation, with more uniform pressure, thereby increasing the cleaning force of the surface cleaning member 210 and ensuring a better cleaning effect.

[0034] Reference Figure 1 As shown, in some examples of this embodiment, the surface cleaning member 210 includes a cleaning support rod and a cleaning cloth, the cleaning cloth is sleeved on the cleaning support rod, and the two ends of the cleaning support rod are respectively connected to the two connecting members 230. It can be understood that the cleaning support rod is used to support the cleaning cloth. The cleaning support rod can be made of a hard material, that is, the cleaning support rod does not undergo obvious deformation during the translation process, while the cleaning cloth can be made of a soft material, which can be deformed when it contacts the light emitting surface 110, thereby generating a larger contact area between the light emitting surface 110 and the light emitting surface 110, further improving the cleaning effect.

[0035] In some examples of this embodiment, the self-cleaning light injection lampshade further includes a controller (not shown), which is electrically connected to the cleaning drive 220. It will be appreciated that the controller can control the start and stop of the cleaning drive 220, thereby controlling the surface cleaning element 210 to clean the light exit surface 110. Furthermore, the controller can be a programmable logic controller (PLC) to facilitate setting the specific operating time and mode of the surface cleaning element 210, thereby completely eliminating operator intervention.

[0036] Furthermore, the present invention also provides a self-cleaning light injection lamp, which may include a light injection light source and a self-cleaning light injection lampshade as described in the above embodiment.

[0037] In some examples of this embodiment, the light injection light source may be a light bar, and the light bar may be installed in a light groove of the lampshade housing 100 .

[0038] Furthermore, the present invention also provides a light injection device. The light injection device may include a light injection chamber and a self-cleaning light injection lamp as described in the above embodiment. The self-cleaning light injection lamp may be disposed in the light injection chamber.

[0039] In some examples of this embodiment, the light injection device further includes a cleaning liquid tank 300 . Figure 2 for Figure 1 Schematic diagram of the structure of the light injection lampshade and the cleaning liquid tank. Figure 2As shown, the cleaning liquid tank 300 is used to hold cleaning liquid. The cleaning liquid tank 300 is arranged on the moving path of the surface cleaning member 210, and the cleaning drive member 220 can drive the surface cleaning member 210 to enter the cleaning liquid tank 300. It can be understood that in actual use, an appropriate amount of cleaning liquid can be added to the cleaning liquid tank 300. When the surface cleaning member 210 enters the cleaning liquid tank 300, the stains attached to its surface can be removed by the cleaning liquid in the cleaning liquid tank 300, and the surface of the surface cleaning member 210 can also absorb some of the cleaning liquid, thereby further improving the cleaning effect.

[0040] In some examples of this embodiment, the cleaning liquid may be selected from volatile liquid substances, for example, the cleaning liquid may be alcohol.

[0041] In some examples of this embodiment, the cleaning liquid tank 300 is disposed in the light injection chamber. Furthermore, the cleaning liquid tank 300 may be connected to a cavity wall of the light injection chamber.

[0042] In some examples of this embodiment, reference is made to Figure 1 and Figure 2 As shown, in some examples of this embodiment, the light emitting surface 110 includes a light-transmitting area 111 and a remaining area 112 located on one side of the light-transmitting area 111, and the cleaning liquid tank 300 is disposed directly below the remaining area 112. It can be understood that light is emitted from the light-transmitting area 111, and thus the area directly below the light-transmitting area 111 is where the light injection process is performed. Placing the cleaning liquid tank 300 below the remaining area 112 effectively utilizes the space below the remaining area 112, avoiding the impact of the cleaning liquid tank 300 on the light injection process. Furthermore, the surface cleaning member 210 can clean only the light-transmitting area 111 without cleaning the remaining area 112.

[0043] Reference Figure 2 As shown, in this embodiment, the shape and position of the transmission belt 222 can be set accordingly according to the required moving path of the surface cleaning member 210 to ensure that the surface cleaning member 210 can contact the light emitting surface 110 for translation and can also move to the cleaning liquid tank 300 located below the remaining area 112.

[0044] The self-cleaning light injection lampshade of the utility model can be Figures 3 to 5 Use in the manner shown. Figures 3 to 5 are all front views of the self-cleaning light injection lampshade, and, Figure 3 This is a front view of the structure when the surface cleaning member 210 is located in the cleaning liquid tank 300. Figure 4 1 is a front view of the structure when the surface cleaning member 210 moves to the point where it begins to contact the light emitting surface 110. Figure 5It is a front view structural diagram of the surface cleaning member 210 when it moves horizontally along the light emitting surface 110 to the tail end.

[0045] Reference Figure 3 As shown, in the initial state, the surface cleaning member 210 can be located in the cleaning liquid tank 300, which can contain cleaning liquid, and the surface cleaning member 210 is immersed in the cleaning liquid. When the cleaning process starts, the driving motor 221 in the cleaning driving member 220 can be started to drive the transmission belt 222 to rotate, as shown in FIG. Figure 3 In the direction shown, the driving motor 221 can drive the transmission belt 222 to rotate clockwise, and the surface cleaning member 210 is then driven to the leftmost end of the light emitting surface 110, that is, Figure 4 Furthermore, as the transmission belt 222 rotates further, the surface cleaning member 210 can move from the leftmost end to the rightmost end of the light emitting surface 110, as shown in FIG. Figure 5 During this movement, the surface cleaning member 210 contacts the light emitting surface 110 and performs a translational motion on the light emitting surface 110, thereby completing the wiping of the light emitting surface 110. Then, as the transmission belt 222 rotates from top to bottom, the position of the connecting member 230 is lowered, and the position of the surface cleaning member 210 is also lowered accordingly. The surface cleaning member 210 is no longer in contact with the light emitting surface 110, and gradually returns from right to left to the cleaning liquid tank 300, as shown in FIG. Figure 3 Through this process, the light emitting surface 110 can be cleaned without disassembling the lampshade housing 100. The surface cleaning member 210 can clean the lampshade housing 100 during the light injection process, eliminating the need to stop the light injection equipment and effectively reducing the risk of operator injury.

[0046] In some examples of this embodiment, the light injection device may further include a heating device, which is used to heat the solar cell, and the light of the self-cleaning light injection lamp can irradiate the solar cell.

[0047] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention.
