Description

Technical Field

[0001] The utility model relates to the photovoltaic field, in particular to a half-cell photovoltaic cell processing and slicing device. Background Art

[0002] Solar power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. Half-cell modules are a module structure that can greatly reduce internal consumption. Its basic principle is to cut the cell into two halves to reduce internal circuit losses. In the prior art, laser scribing is usually used to complete the slicing operation of half-cell photovoltaic cells.

[0003] Specifically, the existing Chinese patent publication number CN209125134U proposes a laser slicing machine for half-cell batteries, which realizes the replacement of the placement plate by setting a rotatable bracket. Therefore, after the processing of half-cell battery is completed, the new placement plate can be quickly replaced to carry the other half-cell battery for processing, thereby preventing the placement plate from remaining processing debris after laser slicing, resulting in poor subsequent slicing effect of the remaining half-cell battery. The surface of the placement plate after processing is cleaned by setting multiple components such as a slide, a lifting platform, a cleaning cloth and a spray head.

[0004] However, the above device has certain defects: for example, when cleaning the surface of the placement plate after processing, it is necessary to first control the lifting platform to descend so that the cleaning cloth contacts the surface of the placement plate, and then control the slide to operate so that the cleaning cloth completely wipes and covers the placement plate, and finally separate the cleaning cloth from the placement plate to prevent interference with the rotation of the placement plate. However, the above steps are too cumbersome, and the cleaning takes too long, which will affect the slicing rate of half-cell cells and is difficult to meet actual application requirements.

[0005] Therefore, a half-cell photovoltaic cell processing and slicing device is needed to solve the above problems. Utility Model Content

[0008] The rotating bracket is rotatably mounted on the frame, and a plurality of the placement plates are fixedly mounted on the rotating bracket in a ring-like shape and at equal intervals;

[0009] The laser slicing assembly is arranged on one side of the frame and is located directly above one of the placement plates;

[0012] The cleaning roller is movably arranged between the conveyor belt and the inner wall of the annular groove, moves along with the conveyor belt, and can be attached to the upper surface of the placement plate or separated from the lower surface of the placement plate;

[0013] The cleaning roller is connected to the inner wall of the annular groove through the linkage member, so that the cleaning roller can rotate while moving.

[0014] Further, the linkage member includes a fixed tooth and a gear ring;

[0015] The fixed teeth are arranged on the inner wall of the annular groove;

[0016] One end of the cleaning roller is connected to the conveyor belt through a fixing frame and can rotate relative to the conveyor belt;

[0017] The toothed ring is fixedly mounted on the outer wall of the cleaning roller and meshes with the fixed teeth.

[0018] Further, the cleaning roller has an initial state and a cleaning state;

[0019] When the cleaning roller is in an initial state, the cleaning roller is placed below the placement plate;

[0020] When the cleaning roller is in a cleaning state, the cleaning roller is in contact with the upper surface of the placement plate.

[0021] Furthermore, the placement plate is wrapped in a space formed by the annular groove.

[0022] Furthermore, the frame has a built-in partition, and the partition is located directly above the rotating bracket to separate the frame into a slicing chamber and a cleaning chamber.

[0023] Furthermore, a waste recycling box is provided on the upper surface of the frame;

[0024] The waste recovery box is arranged just below the cleaning roller.

[0025] Furthermore, the input end of the rotating bracket is connected to a stepping motor.

[0026] Furthermore, a compensation gap is reserved between the side of the support plate facing the placement plate and the placement plate.

[0027] Furthermore, the outer wall of the cleaning roller has a plurality of elastic bristle layers to elastically fit with the upper surface of the placement plate.

[0028] Compared with the prior art, the utility model has at least the following beneficial effects:

[0029] By setting up a cleaning assembly including a support plate with an annular groove, a conveyor belt, a cleaning roller and a linkage, and since the cleaning roller can move with the conveyor belt and, under the action of the linkage, the cleaning roller can move and rotate at the same time, thereby cleaning the upper surface of the placement plate, and since the cleaning roller can be separated from the lower surface of the placement plate when moving with the conveyor belt, there is no need to worry about the cleaning roller interfering with the rotation of the placement plate, that is, it is only necessary to control the operation of the conveyor belt to move the cleaning roller to different positions of the annular groove to achieve the cleaning and anti-interference functions of the surface of the placement plate, thereby effectively reducing the time required for cleaning and achieving the purpose of improving the processing rate of half-cell battery cells.

[0035] The following will be described in more detail with reference to the schematic diagram of the half-cell photovoltaic cell processing and slicing device of the present invention, wherein the preferred embodiment of the present invention is shown. It should be understood that those skilled in the art can modify the present invention described herein and still achieve the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the present invention.

[0036] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0037] like Figures 1 to 4 As shown, an embodiment of the utility model proposes a half-cell photovoltaic cell processing and slicing device, including a frame 1, a rotating bracket 2, a plurality of placement plates 3, a laser slicing component 4 and a cleaning component 5.

[0038] Among them, the rotating bracket 2 is rotatably installed on the frame 1, and a plurality of the placing plates 3 are fixedly installed on the rotating bracket 2 in a ring shape and equidistantly, and are used to replace the placing plates 3, so that half-cell batteries can be placed on a clean placing plate 3 during slicing, avoiding the occurrence of poor slicing effect due to debris remaining on the surface of the placing plate 3 during processing of the previous half-cell battery.

[0039] The laser slicing assembly 4 is arranged on one side of the frame 1 and is located directly above one of the placement plates 3, and is used for slicing half of the battery cell. This is a prior art and will not be described in detail here.

[0040] The cleaning assembly 5 is disposed on the other side of the frame 1 and is used to clean the placement plate 3 with residual debris.

[0041] Specifically, the cleaning assembly 5 includes a support plate 51 , a conveyor belt 52 , a cleaning roller 53 and a linkage member 54 .

[0042] The support plate 51 is provided with an annular groove 511 , and the conveyor belt 52 is installed in the annular groove 511 through the drive of a driving motor.

[0043] Furthermore, the cleaning roller 53 is movably disposed between the conveyor belt 52 and the inner wall of the annular groove 511, and moves along with the conveyor belt 52, and can be attached to the upper surface of the placement plate 3 or separated from the lower surface of the placement plate 3. That is, the cleaning roller 53 moves inside the annular groove 511 along the conveying track of the conveyor belt 52, and when it moves to the upper half of the annular groove 511 (such as Figure 2As shown), it can fit with the upper surface of the placement plate 3, and when it moves to the lower half of the annular groove 511 (as shown Figure 1 As shown), it will be separated from the placement plate 3, ensuring that the existence of the cleaning roller 53 will not interfere with the rotation of the placement plate 3. Therefore, compared with the above-mentioned background technology in which cleaning is completed by a lifting platform and a slide seat, the present device can save the cost required for the power device, and does not require multiple steps to be alternately operated during operation (such as the slide seat can only operate after the lifting platform moves), thereby effectively shortening the time required for cleaning and improving the processing rate of half-cell batteries.

[0044] It should be noted that the cleaning roller 53 is connected to the inner wall of the annular groove 511 through the linkage 54, so that the cleaning roller 53 can rotate while moving. The self-rotation of the cleaning roller 53 during the movement improves the cleaning effect on the upper surface of the placement plate 3.

[0045] The device is provided with a cleaning assembly 5 including a support plate 51 with an annular groove 511, a conveyor belt 52, a cleaning roller 53 and a linkage member 54. Since the cleaning roller 53 can move together with the conveyor belt 52 and, under the action of the linkage member 54, the cleaning roller 53 can move and rotate at the same time, so that the upper surface of the placement plate 3 can be cleaned. Moreover, since the cleaning roller 53 can be separated from the lower surface of the placement plate 3 when moving with the conveyor belt 52, there is no need to worry about the interference of the cleaning roller 53 with the rotation of the placement plate 3. That is, it is only necessary to control the operation of the conveyor belt 52 to move the cleaning roller 53 to different positions of the annular groove 511 to achieve the cleaning and anti-interference functions of the surface of the placement plate 3. Therefore, the time required for cleaning is effectively reduced, thereby achieving the purpose of improving the processing rate of half-cell battery cells.

[0046] In this embodiment, a specific linkage member 54 is provided so that when the cleaning roller 53 moves on the upper surface of the placement plate 3 , the upper surface of the placement plate 3 can be cleaned more thoroughly.

[0047] The linkage member 54 includes a fixed tooth 541 and a gear ring 542 . The fixed tooth 541 is disposed on the inner wall of the annular groove 511 . One end of the cleaning roller 53 is connected to the conveyor belt 52 via a fixed frame and can rotate relative to the conveyor belt 52 .

[0048] The toothed ring 542 is fixedly mounted on the outer wall of the cleaning roller 53 and meshes with the fixed teeth 541. That is, when the cleaning roller 53 moves following the conveyor belt 52, the toothed ring 542 and the fixed teeth 541 mesh together to enable the cleaning roller 53 to rotate, thereby improving the cleaning effect on the surface of the placement plate 3.

[0049] It should be noted that the cleaning roller 53 has an initial state (eg Figure 1as shown) and cleaning status (as shown Figure 2 shown).

[0050] When the cleaning roller 53 is in the initial state, the cleaning roller 53 is placed below the placement plate 3 to ensure that it does not interfere with the movement of the placement plate 3 .

[0051] When the cleaning roller 53 is in a cleaning state, the cleaning roller 53 is in contact with the upper surface of the placement plate 3 to clean the debris remaining on the surface of the placement plate 3 .

[0052] Among them, the placement plate 3 is wrapped in the space formed around the annular groove 511, that is, the upper surface of the placement plate 3 is lower than the top wall of the inner cavity of the annular groove 511, and the lower surface of the placement plate 3 is higher than the bottom wall of the inner cavity of the annular groove 511, so that the cleaning roller 53 can be in contact with the upper surface of the placement plate 3 and separated from the lower surface of the placement plate 3 (that is, it is located below the placement plate 3) during operation.

[0053] In other embodiments, in order to prevent the cleaning roller 53 from interfering with the slicing work of the laser slicing assembly 4 during cleaning and affecting the slicing effect of the half-cell, a partition 6 is built into the frame 1, and the partition 6 is located directly above the rotating bracket 2 to separate the frame 1 into a slicing chamber and a cleaning chamber.

[0054] Preferably, a waste recovery box 7 is provided on the upper surface of the frame 1 , and the waste recovery box 7 is arranged directly below the cleaning roller 53 to recover the residual debris on the surface of the placement plate 3 .

[0055] In other embodiments, the input end of the rotating bracket 2 is connected to a stepping motor so as to complete the replacement of the placement plate 3 under the laser slicing assembly 4 by a single rotation of a specific angle.

[0056] In a further embodiment, a compensation gap is reserved between the side of the support plate 51 facing the placement plate 3 and the placement plate 3 to prevent the placement plate 3 from interfering with the support plate 51 when rotating.

[0057] Furthermore, the outer wall of the cleaning roller 53 has a plurality of elastic bristle layers to elastically fit with the upper surface of the placement plate 3 to improve the cleaning effect of the placement plate 3 .

[0058] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
