Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of photovoltaic cell production equipment. Specifically, the present application relates to a film collecting mechanism and a film collecting device. Background Art

[0002] After the wafers (such as silicon wafers) are produced and tested, they need to be stored in a magazine. In order to allow the wafers to be neatly stacked in the magazine, the magazine is generally tilted.

[0003] To ensure the cleanliness of the blanks, a clean paper pad is typically placed at the bottom of the magazine before they are collected. However, because the magazine is tilted, the paper pad can easily slide and move before the blanks are collected. During the collection process, the paper pad is impacted by the blanks, causing it to shift or wrinkle, resulting in uneven blanks. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a film receiving mechanism, the detailed technical solution of which is as follows:

[0005] A film collecting mechanism includes a material box, the material box includes a bottom plate and limit members arranged around two adjacent sides of the bottom plate, the bottom plate and the limit members forming a storage space for storage;

[0006] At least one suction cup is provided on the feeding end of the bottom plate away from the limiting member.

[0007] The present application provides a film collection mechanism in which a suction cup is provided at the feed end of the bottom plate of the magazine. The suction cup can secure one end of a paper pad placed on the bottom plate to the feed end of the bottom plate, thereby preventing the paper pad from shifting before the film is collected. Furthermore, during the film collection process, when the paper pad is impacted by the film, the suction cup pulls the paper back against the bottom plate, preventing it from shifting or wrinkling.

[0008] In some embodiments, the material box also includes a base, the limit members are arranged at the adjacent first and second sides of the bottom plate, and the feed end is located at the corner of the third and fourth sides of the bottom plate; the bottom plate is tilted on the base, and the feed end of the bottom plate is tilted upward.

[0009] By tilting the bottom plate on the base, the feed end of the bottom plate is tilted upward, so that the material sheets entering from the feed end can slide toward the corners of the third and fourth side edges of the bottom plate until they rest against the limit pieces of the material box, ultimately allowing the material sheets to be stacked more neatly in the storage space of the material box.

[0010] In some embodiments, two suction cups are provided.

[0011] The two suction cups can cooperate to respectively adsorb and fix the two side edges of one end of the padding paper to the feeding end of the bottom plate, thereby improving the adsorption and fixing effect of one end of the padding paper.

[0012] In some embodiments, the suction cup is a van der Waals suction cup.

[0013] When the van der Waals suction cup contacts an object's surface, it creates a vacuum seal, securing the object through van der Waals forces. Using the van der Waals suction cup to hold the paper pad eliminates the need for an air source or air pipe, reducing equipment costs and preventing interference with the movement of the cartridge.

[0014] In some embodiments, the sheet collecting mechanism further comprises at least one blowing assembly, which is disposed on a side of the feeding end of the bottom plate and is configured to blow air toward the feeding end of the bottom plate.

[0015] Since the surface of the padding paper is not smooth enough, when the first sheet is collected, the friction between the padding paper and the sheet may prevent the sheet from sliding into place. However, by providing an air blowing component, air can be blown towards the sheet, thereby pushing the sheet to slide into place.

[0016] In some embodiments, the blowing assembly includes an adjustment bracket and a blowing piece, the blowing piece is connected to the adjustment end of the adjustment bracket; the blowing piece is configured to blow toward the feeding end of the base plate; the adjustment bracket is configured to adjust the blowing angle of the blowing piece.

[0017] By setting the blowing component, the blowing angle of the blowing component is flexibly adjusted, ensuring that the blowing component can blow toward the feeding end of the bottom plate at a suitable angle.

[0018] In some embodiments, the adjustment bracket includes a support column and an adjustment rod, wherein the support column is arranged on the side of the feeding end of the base plate, the first end of the adjustment rod is rotatably connected to the support column, and the blowing member is connected to the second end of the adjustment rod.

[0019] An adjustment bracket with a simple structure is provided, which can quickly adjust the blowing angle of the blowing member manually.

[0020] In some embodiments, the blowing part includes a blowing block and an air connecting head, wherein: the blowing block is connected to the adjustment end of the adjustment bracket, an air cavity is provided in the blowing block, and the surface of the blowing block facing the material box has a blowing seam connected to the air cavity; the air connecting head is provided on the blowing block and connected to the air cavity, and the air connecting head is connected to the compressed air source.

[0021] After the compressed air supplied by the compressed air source enters the air cavity, it is blown at high speed from the blowing slit toward the feeding end of the bottom plate, thereby ensuring that the first sheet is pushed into the storage space.

[0022] In some embodiments, the sheet collecting mechanism includes two groups of blowing components, and the two groups of blowing components blow air toward the feeding end of the bottom plate from adjacent two sides of the feeding end of the bottom plate respectively.

[0023] By setting up two sets of blowing components, when the first sheet is collected, the two sets of blowing components blow air synchronously towards the two adjacent sides of the sheet, so that the sheet can slide into place more smoothly, and the other two sides of the sheet can both rest against the limiting parts at the corresponding sides of the material box.

[0024] The present application also provides a film receiving device, which includes a conveying mechanism and any of the above-mentioned film receiving mechanisms, wherein: the conveying mechanism is arranged above the film receiving mechanism, and the conveying mechanism is used to convey the carried material sheet into the material box of the film receiving mechanism.

[0025] Through the cooperation of the conveying mechanism and the sheet collecting mechanism, the sheet collecting device realizes automatic loading of the sheet, so that the sheet is automatically stacked into the material box. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0034] like Figures 1 to 3As shown, the sheet collection mechanism in the embodiment of the present application includes a magazine 1, which includes a bottom plate 11 and stoppers 12 disposed around two adjacent sides of the bottom plate 11. The bottom plate 11 and the stoppers 12 form a storage space for storing sheets. At least one suction cup 24 is provided at an inlet end A of the bottom plate 11, away from the stoppers 12.

[0035] The sheet collecting mechanism provided in the embodiment of the present application is suitable for collecting material sheets (such as silicon wafers). Because a suction cup 14 is provided at the feed end A of the base plate 11. Before the formal collection of the sheet, the suction cup 14 can fix one end of the padding paper laid on the base plate 11 at the feed end A of the base plate 11, thereby preventing the padding paper from moving before the sheet is collected. In addition, during the sheet collection process, when the padding paper is impacted by the material sheet, the reverse pull of the suction cup 14 keeps the padding paper tightly against the bottom of the base plate 11, thereby preventing the padding paper from shifting or wrinkling.

[0036] Optionally, the material box 1 further includes a base 13, and a limiting member 12 is arranged at adjacent first and second sides of the bottom plate 11. For example, the limiting member 12 includes two limiting posts arranged at the first side of the bottom plate 11 and two limiting posts arranged at the second side of the bottom plate 11. The third and fourth sides of the bottom plate 11 are open, and the feed end A is located at the corner of the third and fourth sides of the bottom plate 11. In particular, the bottom plate 11 is tilted on the base 13, and the feed end A of the bottom plate 11 is tilted upward.

[0037] like Figure 3 As shown, by tilting the bottom plate 11 on the base 13, the feed end A of the bottom plate 11 is tilted upward, so that the material sheets entering from the feed end A can slide toward the corners B of the third and fourth sides of the bottom plate 11 until they rest against the limit members 12 at the first and second sides of the material box 1, ultimately allowing the material sheets to be more neatly stacked in the storage space of the material box 1.

[0038] Optionally, a support block 15 is provided on the base 13 , and the bottom plate 11 is tiltedly supported on the base 13 by the support block 15 .

[0039] Optionally, two suction cups 14 are provided. The two suction cups 14 cooperate to absorb and fix the two sides of one end of the pad paper to the feeding end A of the bottom plate 11, thereby improving the absorption and fixing effect of the pad paper.

[0040] Optionally, suction cup 14 is a van der Waals suction cup. When in contact with the surface of an object, a van der Waals suction cup forms a vacuum seal, thereby securing the object via van der Waals forces. Therefore, using a van der Waals suction cup to absorb the paper pad eliminates the need for an air source and air pipe, reducing equipment costs and preventing interference with the movement of the cartridge 1.

[0041] Because the surface of the padding paper is not smooth enough, when the first sheet is collected, the friction between the padding paper and the sheet may prevent the sheet from sliding into place. Figure 1 As shown, optionally, the sheet collecting mechanism in the embodiment of the present application further includes at least one blowing assembly 2, which is arranged on the side of the feeding end A of the bottom plate 11. The blowing assembly 2 is configured to blow air toward the feeding end A of the bottom plate 11, thereby overcoming the friction resistance of the padding paper and pushing the first sheet to slide into place, that is, sliding to the two sides of the first sheet against the limiters 12 at the first side and the second side respectively. Since the sheet generally has a smooth surface, the sheet other than the first sheet can basically slide smoothly into the material box 1 along the smooth surface of the previous sheet. Therefore, after completing the collection of the first sheet, the blowing assembly 2 can be turned off, the blowing can be stopped, and the gas consumption can be saved. In addition, since the suction cup 14 can adsorb and fix the padding paper, it can prevent the blowing assembly 2 from blowing the padding paper away when blowing.

[0042] Optionally, the blowing assembly 2 includes an adjustment bracket 22 and a blowing member 21, wherein the blowing member 21 is connected to the adjustment end of the adjustment bracket 22. The blowing member 21 is configured to blow air toward the inlet end A of the bottom plate 11. The adjustment bracket 22 is configured to adjust the blowing angle of the blowing member 21.

[0043] Optionally, the adjustment bracket 22 includes a support column 221 and an adjustment rod 222. The support column 221 is vertically disposed on the side of the feed end A of the base plate 11. The first end of the adjustment rod 222 is rotatably connected to the support column 221, and the blowing member 21 is connected to the second end of the adjustment rod 222. By manually pushing the adjustment rod 222 to rotate about the support column 221, the blowing angle of the blowing member 21 can be flexibly adjusted to ensure that the blowing member 21 blows air at an appropriate angle toward the feed end A of the base plate 11.

[0044] like Figure 1 As shown, optionally, the sheet collecting mechanism in the embodiment of the present application includes two groups of blowing components 2, and the two groups of blowing components 2 blow air toward the feed end A of the bottom plate 11 from adjacent two sides of the feed end A of the bottom plate 11, so that the sheet can slide into place more smoothly and ensure that both side edges of the sheet can abut against the limit members 12 at the corresponding side edges of the material box.

[0045] like Figure 4 As shown, optionally, the blowing member 21 includes a blowing block 211 and an air connection head 212, wherein: the blowing block 211 is connected to the adjustment end of the adjustment bracket 22, an air cavity is provided in the blowing block 211, and the surface of the blowing block 211 facing the material box has a blowing slit 213 connected to the air cavity. The air connection head 212 is provided on the blowing block 211 and connected to the air cavity, and the air connection head 212 is connected to the compressed air source.

[0046] The compressed air supplied by the compressed air source enters the air cavity through the air connection head 212 and is blown out at high speed from the air blowing slit 213 toward the feeding end A of the bottom plate 11 , thereby pushing the first tablet into the storage space of the material box 1 .

[0047] Continue to refer Figure 1 As shown, in order to prevent the magazine 1 from sliding or slipping during the film collection process, the film collection mechanism in the embodiment of the present application optionally further includes a supporting bracket 3 for supporting and fixing the magazine.

[0048] The present application also provides a sheet collecting device, comprising a conveying mechanism and the sheet collecting mechanism provided by any of the above embodiments, wherein the conveying mechanism is disposed above the sheet collecting mechanism and is configured to convey the loaded sheet into a magazine of the sheet collecting mechanism. Through the cooperation of the conveying mechanism and the sheet collecting mechanism, the sheet collecting device automatically loads the sheet, so that the sheet is automatically stacked into the magazine.

[0049] The conveying mechanism can adopt an existing adsorption conveying line, which has adsorption and conveying functions, that is, the adsorption conveying line can be used to adsorb and convey the sheet into the material box, so that the sheet is automatically stacked in the material box.
