Description

Technical Field

[0001] The utility model relates to the technical field of energy storage batteries, and specifically provides a trough type machine debris cleaning device and a solar cell production line. Background Art

[0002] Solar cells are devices that directly convert light energy into electricity through the photoelectric or photochemical effects. During the wet process of producing solar cells using a trough-type machine, the solar cells are placed in a tank filled with a chemical solution. This process inevitably generates a significant amount of debris from the solar cells placed in the wet process equipment. If this debris is not promptly cleaned, it can affect product yield and disrupt the proper functioning of the circulation and drainage systems (for example, due to pump damage or pipe blockage).

[0003] like Figure 1 As shown, the existing method for cleaning debris generated during the wet process of producing solar cells in a trough machine involves first stopping the wet process equipment, draining the liquid from the trough housing the solar cells, and then using an acid-base vacuum cleaner to remove the debris. This cleaning method requires draining the liquid from the trough housing the solar cells before removing the debris. If the liquid is drained before reaching the end of its useful life when debris cleaning is necessary, it results in waste and increased production costs.

[0004] Regarding the problem of cleaning the tank debris, in practical applications, such as Figure 2 As shown, a slot-type chip splicing box is designed, which includes an embedded slot frame built into the cleaning slot, and a flow plate is provided on the inner side of the embedded slot frame. The flow plate is provided with a number of connecting holes for the cleaning liquid in the cleaning slot to flow. Figure 1 The difference is that traditional tanks have separate flow dividers, which can easily cause debris to fall under the flow dividers, making it difficult to clean. However, the flow dividers in this debris collection box are integrated with the built-in tank frame, preventing the risk of tank debris falling under the flow dividers and becoming difficult to clean. If there's liquid medicine in the tank, the built-in tank frame can be manually raised using a handle to remove the debris.

[0005] While this debris splicing box allows for debris removal without draining liquid, the actual debris removal process requires an operator to stand next to the cleaning tank and lift the embedded tank frame from the cleaning tank. Due to the limited space between adjacent tanks arranged on the production line, operators face difficulty in lifting the embedded tank frame due to insufficient standing space. Furthermore, lifting the embedded tank frame from a cleaning tank filled with corrosive liquid in the confined space presents a potential risk of injury to the operator. Utility Model Content

[0006] The utility model aims to solve the above technical problem, that is, to solve the existing problem that manual operation of lifting the trough body is inconvenient and dangerous due to limited operating space.

[0007] In the first aspect, the utility model provides a trough-type machine debris cleaning device, comprising: a cleaning trough, in which an inner trough body is arranged, and the inner trough body is overlapped with the side wall of the cleaning trough through an overlap portion arranged at its upper port; a clamping and moving device, which is arranged above the inner trough body, and the clamping and moving device is connected to the overlap portion by moving relative to the cleaning trough, so as to enable the inner trough body to move up and down relative to the cleaning trough.

[0008] Furthermore, the clamping and moving device includes: a horizontal platform, which is arranged above the cleaning tank; a first driving device, which is arranged on the horizontal platform; support rods, which are arranged on both sides of the horizontal platform and extend downward to both sides of the cleaning tank; wherein, the support rods are connected to the first driving device, and the support rods can move back and forth in the horizontal direction relative to the side walls of the cleaning tank under the drive of the first driving device.

[0009] Furthermore, the clamping and moving device also includes a second driving device, which is connected to the horizontal platform and is used to drive the clamping and moving device to move up and down relative to the cleaning tank.

[0010] Furthermore, the clamping and moving device further includes a control device, which is electrically connected to the first driving device and the second driving device respectively, and is used to control the operation of the first driving device and the second driving device.

[0011] Furthermore, the support rod includes a vertical portion and a supporting portion; the vertical portion is connected to the first driving device; the supporting portion is located at the lower end of the vertical portion, and the supporting portion can abut against the overlapping portion of the inner trough from below.

[0012] Furthermore, the support rod also includes a horizontal portion arranged on the horizontal platform, the horizontal portion is arranged parallel to the horizontal platform and connected to the vertical portion of the support rod; a guide rail is also provided on the horizontal platform, and the horizontal portion of the support rod is placed on the guide rail to limit the horizontal movement of the support rod.

[0013] Furthermore, a guide rail bracket is provided on the horizontal platform for placing the guide rail.

[0015] Furthermore, a supporting structure is provided at the bottom of the inner tank.

[0030] like Figure 3 As shown, the embodiment of the present application provides a trough machine debris cleaning device for use in the preparation process of solar cells prepared by a wet method. The cleaning device includes: a cleaning trough 1, an inner trough body 2 and a clamping and moving device 3.

[0031] Specifically, the cleaning tank 1 is used to hold the chemical solution required for preparing solar cells. The cleaning tank 1 is typically a rectangular tank with an open top, but can also be configured into other shapes as needed, such as a trapezoidal tank. The present embodiment does not specifically limit the shape of the cleaning tank 1.

[0032] The inner tank body 2 is used to place the solar cell wafers to be prepared. The inner tank body 2 is placed in the cleaning tank 1 from the opening at the upper end of the cleaning tank 1 and can also be taken out from the cleaning tank 1. The inner tank body 2 is also a tank body with an upper end opening, and through holes are provided on the bottom surface and side walls of the inner tank body 2 for the circulation of the medicinal liquid in the cleaning tank 1. The shape of the inner tank body 2 can be the same as that of the cleaning tank 1; or the shape of the inner tank body 2 can be set to be different from the shape of the cleaning tank 1 as needed. The embodiment of the present application does not specifically limit the shape of the inner tank body 2, as long as the inner tank body 2 can be placed in the cleaning tank 1 from the opening at the upper end of the cleaning tank 1 and can also be taken out from the cleaning tank 1. When the inner tank body 2 is placed in the cleaning tank 1, the inner tank body 2 overlaps the side wall of the cleaning tank 1 through the overlapping portion 21 provided at its upper port.

[0033] In a specific embodiment, the overlapping portion 21 can be a flange structure formed by the side wall of the inner tank body 2 extending horizontally outward at the upper end, and the flange structure is placed on the side wall of the cleaning tank 1 and extends outward; it can also be a bent structure formed outward at the upper end of the inner tank body 2, such as Figure 3 As shown, the bending structure forms a groove structure with the side wall of the inner tank body 2, and the side wall close to the upper end of the cleaning tank 1 is inserted into the groove structure. The embodiment of the present application does not specifically limit the structure of the overlapping portion 21.

[0034] The clamping and moving device 3 is arranged above the inner tank body 2. It connects with the overlapping portion 21 of the inner tank body 2 by moving relative to the cleaning tank 1, so as to move the inner tank body 2 up and down relative to the cleaning tank 1, that is, to lift the inner tank body 2 from the cleaning tank 1; then, the inner tank body 2 is lowered and placed in the cleaning tank 1.

[0035] like Figures 3 to 5 As shown, the clamping and moving device 3 includes: a horizontal platform 31 , a first driving device 32 and a support rod 33 .

[0036] Specifically, a horizontal platform 31 is disposed above the cleaning tank 1; a first drive device 32 is disposed on the horizontal platform 31; and support rods 33 are disposed on both sides of the horizontal platform 31 and extend downward to both sides of the cleaning tank 1. The support rods 33 are connected to the first drive device 32 and, driven by the first drive device 32, can reciprocate horizontally relative to the sidewalls of the cleaning tank 1.

[0037] Usually, an equal number of support rods 33 are symmetrically arranged on both sides of the horizontal platform 31, and each support rod 33 is connected to a first driving device 32. The first driving device 32 drives the support rod 33 connected thereto to reciprocate in the horizontal direction relative to the side wall of the cleaning tank 1, that is, the support rod 33 can approach or leave the side wall of the cleaning tank 1 under the drive of the first driving device 32.

[0038] In a specific embodiment, Figure 3 and Figure 4 As shown, two support rods 33 are symmetrically arranged on both sides of the horizontal platform 31, and correspondingly, four cylinders are correspondingly arranged on the horizontal platform 31 as the first drive device 32. Each support rod 33 is connected to the telescopic end of a cylinder, and the cylinder controls the extension or contraction of its telescopic end to control the support rod 33 connected to the telescopic end of the cylinder to leave or approach the side wall of the cleaning tank 1. The number and arrangement of the support rods 33 can be set as needed, and the embodiment of the present application does not specifically limit this. In addition, the specific form of the first drive device 32 can be selected as needed, and the embodiment of the present application does not specifically limit this.

[0039] The clamping and moving device 3 in the embodiment of the present application further includes a second drive device and a control device (neither of which is shown in the figure). The second drive device is connected to the horizontal platform 31 and is used to drive the clamping and moving device 3 to move up and down relative to the cleaning tank 1, thereby driving the support rod 33 to move up and down. The control device is electrically connected to the first drive device 32 and the second drive device respectively to control the operation of the first drive device 32 and the second drive device.

[0040] Furthermore, if Figure 3 As shown, the support rod 33 includes a vertical portion 331 and a support portion 332; the vertical portion 331 is connected to the first drive device 32; the support portion 332 is located at the lower end of the vertical portion 331, and the support portion 332 can abut against the overlap portion 21 of the inner tank body 2 from below. The support rod 33 can be L-shaped or J-shaped. In a specific embodiment, a cylinder is used as the first drive device 32, and the vertical portion 331 of the support rod 33 is connected to the telescopic end of the cylinder. The cylinder drives the vertical portion 331 to push and pull to control the support rod 33 to move closer to or away from the side wall of the cleaning tank 1.

[0041] The control device controls the support rod 33 via the first drive device 32 to move toward the side wall of the cleaning tank 1, so that the support rod 33 moves until its support portion 332 is located below the overlapping portion 21 of the inner tank body 2 and opposite the overlapping portion 21. The control device then controls the horizontal platform 31 via the second drive device to drive the support rod 33 upward, so that the support portion 332 of the support rod 33 abuts the overlapping portion 21 of the inner tank body 2. Thereafter, the support rod 33 continues to move upward, lifting the inner tank body 2 from the cleaning tank 1 until the bottom surface of the inner tank body 2 is higher than the liquid level of the medicinal solution contained in the cleaning tank 1, thereby facilitating the subsequent cleaning of debris from the inner tank body 2.

[0042] To reduce the vertical force exerted by the support rod 33 on the first drive device 32 during horizontal movement and to enhance the stability of the movement of the support rod 33, the support rod 33 further includes a horizontal portion 333 disposed on the horizontal platform 31. The horizontal portion 333 is disposed parallel to the horizontal platform 31 and is connected to the vertical portion 331 of the support rod 33. A guide rail 34 is also provided on the horizontal platform 31, and the horizontal portion 333 of the support rod 33 is placed on the guide rail 34 to limit the horizontal movement of the support rod 33.

[0043] like Figure 5 As shown, in order to facilitate the simultaneous arrangement of the first drive device 32 and the guide rail 34 on the horizontal platform 31, a guide rail bracket 35 is further provided on the horizontal platform 31. Preferably, the guide rail bracket 35 adopts a hollow structure, so that the first drive device 32 can be arranged directly on the horizontal platform 31 and below the guide rail bracket 35, while the guide rail 34 is arranged on the guide rail bracket 35. This places the guide rail 34 and the first drive device 32 on two upper and lower layers, fully utilizing the height space and making the arrangement more reasonable.

[0044] The support rod 33 is typically made of metal, such as stainless steel. However, the liquid medicine in the cleaning tank 1 is corrosive. Consequently, the liquid medicine in the cleaning tank 1 can corrode the support rod 33. To prevent this, the support rod 33 can be covered with a PP sheet to protect it, preventing the liquid medicine in the cleaning tank 1 from corroding the support rod 33 and thus affecting its strength.

[0045] Furthermore, when the inner tank body 2 is placed in the cleaning tank 1, if the bottom surface of the inner tank body 2 is in contact with the bottom surface of the cleaning tank 1 or the distance between the two is very small, the liquid medicine between the two bottom surfaces will generate an adsorption force between the two bottom surfaces. This will require a greater force to lift the inner tank body 2 from the cleaning tank 1, thereby increasing the output power of the second drive device and the load borne by the support rod 33. To avoid this situation, a support structure 22 is provided at the bottom of the inner tank body 2 to maintain an appropriate distance between the bottom surface of the inner tank body 2 and the bottom surface of the cleaning tank 1, thereby eliminating the adsorption force generated by the liquid medicine between the two bottom surfaces.

[0046] The trough-type machine debris cleaning device in the embodiment of the present application drives the support rod 33 in the clamping device 3 to move horizontally and up and down respectively through the first drive device 32 and the second drive device, so that the support portion 332 of the support rod 33 abuts against the overlapping portion 21 of the inner tank body 2, and the inner tank body 2 is lifted up from the cleaning tank 1 to facilitate the subsequent debris cleaning work. The trough-type machine debris cleaning device in the embodiment of the present application can complete the lifting and lowering operation of the inner tank body 2 by controlling the clamping device 3 within a limited operating space, without the need for manual operation on site. The device has a simple structure, which saves manpower and improves work efficiency. It not only avoids the operational difficulties caused by the lack of standing space for the operator to operate manually on site, but also eliminates the potential risk of work-related injuries during the operator's manual operation on site, such as burns on the skin from the corrosive liquid in the cleaning tank 1, or being hit in a narrow space.

[0047] An embodiment of the present application further provides a solar cell production line, which includes the trough machine debris cleaning device as described in any of the above embodiments.

[0048] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
