Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics and new energy, in particular to a simple device for preventing a chain machine from falling into water. Background Art

[0002] Due to its special structure, TOPCON solar cells need to be etched on the back of the borosilicate glass (BSG) before alkali polishing. At the same time, to protect the borosilicate glass (BSG) on the front of the cell, a layer of water film is often added to the surface of the front borosilicate glass (BSG). When the water film is thin, it cannot effectively protect the front borosilicate glass (BSG); when the water film is thick, it will cause the water film to fall off, reduce the acid tank concentration, and affect the etching effect on the back.

[0003] At present, the method of preventing water from falling is limited to adjusting the level of the rollers of the conveyor to prevent the water film loaded by the battery cells from shaking and falling during operation. For this reason, this application discloses a simple device to prevent the chain conveyor from falling. Utility Model Content

[0004] The utility model aims to solve the existing problems and provides a simple device for preventing a chain machine from falling into water.

[0005] The utility model is realized through the following technical scheme: a simple device for preventing a chain conveyor from dropping water, comprising a roller conveyor, wherein platforms for placing films are respectively arranged at both ends of the roller conveyor, and the roller conveyor is driven by a double sprocket structure, a trough box is arranged below the roller of the roller conveyor, a water trough is arranged between two adjacent rollers on the roller conveyor, and a port of the water trough is lower than the top edge of the roller on the roller conveyor.

[0006] As a further improvement to the above solution, the slot of the slot box is lower than the top edge of the roller of the conveyor, so as to ensure that the roller on the roller conveyor can effectively convey the battery cells.

[0007] As a further improvement to the above scheme, the trough box contains an acid solution for etching treatment, and the liquid level of the acid solution is at 1 / 2-2 / 3 of the height of the roller, which is used to ensure that the acid solution attached to the surface of the roller is effectively and evenly applied to the lower surface of the battery cell during the rotation of the roller.

[0008] As a further improvement to the above scheme, the side surface of the water chute close to the outer curved surface of the roller is set to match the curved surface of the roller, and a gap is left between the curved outer surfaces on both sides of the water chute and the curved surface of the roller to ensure the normal rotation of the roller. At the same time, the gap between the curved outer surfaces on both sides of the water chute and the curved surface of the roller is as small as possible to prevent water from falling from the gap into the acidic solution in the trough box to ensure that the concentration of the acidic solution remains stable.

[0009] Compared with the prior art, the utility model has the following advantages: simple structure, reasonable design, novel and unique concept. By adding a water droplet in the roller conveyor, water droplets falling from the battery cell can be collected to prevent them from falling into the acid solution in the trough box to reduce the conductivity of the acid solution, thereby ensuring the etching effect while avoiding reducing the acid consumption. The water droplet fills the gap between the rollers, limits the vibration of the rollers, makes the displacement of the battery cell more stable, and reduces the falling of water film on the surface of the battery cell.

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] like Figures 1 to 3 As shown in the figure, a simple device for preventing a chain conveyor from falling into water comprises a roller conveyor 1, wherein platforms 12 for placing films are respectively arranged at both ends of the roller conveyor 1, which are supported by brackets 14, and the roller conveyor 1 is driven by a double sprocket 13 structure, a trough box 3 is arranged under the roller 11 of the roller conveyor 1, and a water trough 2 is arranged between two adjacent rollers 11 on the roller conveyor 1, and the port of the water trough 2 is lower than the top edge of the roller 11 on the roller conveyor 1.

[0015] As a further improvement to the above solution, the notch of the trough box 3 is lower than the top edge of the roller 11 of the conveyor, so as to ensure that the roller 11 on the roller conveyor 1 can effectively convey the battery cells.

[0016] As a further improvement to the above scheme, the trough box 3 contains an acid solution for etching treatment, and the liquid level of the acid solution is at 1 / 2-2 / 3 of the height of the roller 11 (submerging 1 / 2-2 / 3 of the roller cross-section), which is used to ensure that the acid solution attached to the surface of the roller 11 is effectively and evenly applied to the lower surface of the battery cell during the rotation of the roller 11.

[0017] As a further improvement to the above scheme, the side surface of the water chute 2 close to the outer curved surface of the roller 11 is set to match the curved surface 21 of the roller 11, and a gap is left between the outer surfaces of the curved surface 21 on both sides of the water chute 2 and the curved surface of the roller 11 to ensure the normal rotation of the roller. At the same time, the gap between the outer surfaces of the curved surface 21 on both sides of the water chute 2 and the curved surface of the roller 11 is as small as possible to prevent water from falling from the gap into the acidic solution in the trough box 3 to ensure that the concentration of the acidic solution remains stable.

[0018] The working principle of a simple device for preventing chain conveyors from dropping water is as follows: the roller conveyor 1 is driven to operate by chain transmission, and the platforms 12 on both sides are used to place battery cells. The acid solution is injected into the trough box 3 to a liquid level of 1 / 2-2 / 3 of the end cross section of the roller 11. The roller conveyor 1 works to convey the battery cells placed on the roller 11. A water film is attached to the surface of the battery cells. The lower surface of the battery cells is etched by the acid solution in the trough box 3. The vibration of the battery cells causes the water in the water film on the upper surface to fall into the water trough 2 and avoid falling into the trough box 3, thereby ensuring the concentration of the acid solution and reducing the acid consumption.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
