[0029] Embodiment 1

[0030] As Figs. 1-4 shown, the utility model provides a technical scheme:

[0031] A device for solar cell piece cleaning, which at least includes but is not limited to operation box 1 and the receiving plate 2 that can slide open relative to operation box 1;The receiving plate 2 is arranged below the silicon wafer work area in operation box 1, and the material box 3 is also arranged below the receiving plate 2;When the receiving plate 2 is subjected to horizontal tension, at least part of the plate body can be separated to the coverage range of operation box 1.

[0032] Based on the above structure, the receiving plate 2 is arranged outside the silicon wafer work area of operation box 1, which can receive the possible silicon wafer fragments, and after receiving, the receiving plate 2 can be pulled out of the area where operation box 1 is located, and the operator can quickly clean the fragments, which can greatly save the processing time of the fragments and will not affect the whole process.

[0033] As an example, the receiving plate 2 can be arranged in parallel along the vertical direction of operation box 1, and each receiving plate 2 is arranged at a predetermined position.

[0034] Based on the above structure, two receiving plates 2 can continuously and uninterruptedly receive fragments;When the first receiving plate 2 is pulled out of the working range of operation box 1 for fragment cleaning, the second receiving plate 2 is still in operation box 1 for receiving operation, which will not affect the whole process and ensure that all fragments can be collected and processed.

[0035] As an example, the operation box 1 can include a first observation window 11 and a second observation window 12, and the first observation window 11 and the second observation window 12 are symmetrically arranged, and the receiving plate 2 is arranged below the first observation window 11 or the second observation window 12.

[0036] Based on the above structure, the observation window can be set to directly observe the internal silicon wafer operation, which makes the whole working process more clear, and also can timely observe the accumulation of fragments, and when the accumulation reaches the specified position, the operator needs to pull out the receiving plate 2 for cleaning.

[0037] As an example, the operation box 1 can also include a feeding port 13 and a discharge port 14, and the feeding port 13 and the discharge port 14 are symmetrically arranged, and the receiving plate 2 is arranged below the plane where the bottom position connecting line of the feeding port 13 and the discharge port 14 is located, which can avoid the interference of the receiving plate 2 to the working area of the silicon wafer.

[0038] As an example, the work box 1 is also provided with a connecting groove 15 matched with the receiving plate 2 and a supporting rail 16; the supporting rail 16 is arranged in parallel in the work box 1, and the receiving rail is provided with a guide groove 21 matched with the supporting rail 16; the supporting rail 16 is arranged in the guide groove 21.

[0039] Based on the above structure, through the cooperation of the supporting rail 16 and the guide groove 21, the support of the receiving plate 2 can be realized, and at the same time, the sliding in and out of the receiving plate 2 can be guided, so that the receiving plate 2 can move along the predetermined area, and the cross section of the guide groove 21 can be C-shaped structure.

[0040] As an example, the size of the connecting groove 15 is not less than the size of the largest size of the side wall of the receiving plate 2, so that when the receiving plate 2 is loaded with fragments, the connecting groove 15 does not interfere with the stacked fragments, and the fragments can be completely transported out of the work box 1.

[0041] As an example, a plurality of supporting pulleys 17 can be arranged along the length direction of the supporting rail 16, the supporting pulley 17 is provided with a supporting connecting rod 18 at the center, and the supporting pulley 17 is connected with the supporting rail 16 through the supporting connecting rod 18.

[0042] And the size of the supporting pulley 17 is matched with the size of the guide groove 21.

[0043] Based on the above structure, through the cooperation of the supporting pulley 17 and the guide groove 21, the push-pull process of the receiving plate 2 can be more smooth, and the fragments can be prevented from falling off during the sliding process.

[0044] As an example, the end of the receiving plate 2 can be provided with a handle 22, and the handle 22 is symmetrically arranged along the length direction of the receiving plate 2.

[0045] Based on the above structure, the handle 22 can quickly pull the receiving plate 2, and since the width of the whole receiving plate 2 is large, the problem of uneven stress may exist when one handle 22 is used to pull, therefore, two symmetric handles 22 are arranged in the present scheme, which can make the whole pulling process more stable.

[0046] As an example, the receiving plate 2 can include a plate body part 23 and a frame part 24, and the frame part 24 is arranged around the contour of the plate body, so that the frame part 24 and the plate body part 23 form a stepped structure.

[0047] Based on the above structure, since the fragments need to be taken out and disposed after being collected, the cavity for receiving the fragments does not need to be arranged too deep, which can reduce the overall weight and facilitate the later taking, and also facilitate the clean disposal of the fragments.

[0048] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
