Description

Technical Field

[0001] The utility model belongs to the technical field of perovskite batteries, and in particular relates to a peelable adhesive printing device for preparing perovskite battery sheets. Background Art

[0002] When perovskite cells are produced in the laboratory, one of the important steps is to drip perovskite onto the mesoporous layer of the cell.

[0003] To ensure the production quality of perovskite cells, high-temperature tape needs to be pasted on the non-glue-dispensing area of ​​the semi-finished cell before adding perovskite. Figure 8 As shown, the semi-finished battery cell array is placed on the experimental substrate, and then high-temperature tape is used to stick the cells horizontally and vertically to fix the cells on the substrate. However, this operation method is time-consuming and labor-intensive, and significantly prolongs the experimental cycle.

[0004] Common screen printing techniques involve applying pressure to a screen with one edge of a squeegee, forcing the ink on the screen through the screen and onto the substrate. The squeegee maintains line contact with the screen as it sweeps across the screen, and the downward pressure is transferred through the squeegee to the substrate. If this printing technique were to be used, printing peelable adhesive around the edges of the cell would allow for rapid tape application. However, with traditional printing methods, the downward pressure from the squeegee can collapse the cell's mesoporous layer, compromising product functionality and hindering the use of screen printing. Utility Model Content

[0005] The purpose of the present utility model is to provide a peelable adhesive printing device for the preparation of peroximate solar cells to solve the above-mentioned problems, so as to achieve the purpose of quickly printing peelable adhesive on the four edges of the solar cell using screen printing technology, while ensuring that the solar cell will not be damaged by the pressure of scraping glue.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1-Figure 7 The present invention provides a peelable adhesive printing device for preparing perovskite solar cells, comprising:

[0028] Support frame 1, both ends of the support frame 1 are fixedly connected with bosses 2, the top of the support frame 1 is downwardly provided with a through slot 3, both sides of the through slot 3 are slidably connected with clamping components, the sliding direction of the clamping component is perpendicular to the length direction of the clamping component, a spacing adjustment member is provided between the clamping component and the support frame 1, and a wire mesh 10 is detachably connected between the two clamping components, the wire mesh 10 is provided corresponding to the through slot 3, and the wire mesh 10 is located above the battery cell;

[0029] The scraper assembly includes a scraper clamp 17 . A plurality of special-shaped scrapers 18 are provided at the bottom of the scraper clamp 17 . The special-shaped scrapers 18 are respectively aligned with the printing positions of the screen 10 .

[0030] The main function of the boss 2 is to ensure that the support frame 1 is above the battery cell and protect the battery cell from being squeezed; the main function of the clamping assembly is to connect the edges of the wire mesh 10 and support the wire mesh 10 above the through groove 3; the main function of the spacing adjustment member is to open the wire mesh 10 and maintain a certain tension by separating the two clamping assemblies after the clamping assembly clamps the wire mesh 10; the main function of the wire mesh 10 is to leak the peelable glue to the target position on the substrate; the main function of the special-shaped scraper 18 is to scrape and press the missing printing position on the wire mesh 10 so that the peelable glue on the wire mesh 10 is printed on the substrate. On the whole, the present invention utilizes screen printing technology, and utilizes the scraper on the scraper clamp to scrape the peelable glue on the screen, so that the peelable glue is printed from the missed printing area on the screen to the gap between the two battery cells on the substrate, thereby achieving the effect of printing the peelable glue in the horizontal gap between the battery cells. At the same time, it can effectively prevent the battery cells from being squeezed and damaged. Similarly, vertical printing is performed. Compared with the traditional method of manually applying high-temperature tape, it can ensure that the battery cell fixing operation is simple, there are no bubbles after fixing, and the work efficiency is high, which can further shorten the experimental cycle.

[0031] To further optimize the solution, when making the screen 10, the film size is made to match the gap between the cells. Several films are placed side by side in fixed positions on the screen 10 to ensure that after the screen 10 is exposed, the exposed area of ​​the peelable adhesive is the same as the gap between the cells. Furthermore, the length of the shaped squeegee 18 is also consistent with the film size, ensuring that the shaped squeegee 18 does not exert pressure on the cells during scraping.

[0032] A further optimized solution is that the clamping assembly includes a lower splint 5, both ends of which are slidably connected to the top of the support frame 1, and the top of the lower splint 5 away from the edge of the through groove 3 is hinged to the upper splint 6 through the rotating shaft 7. A locking part is provided between the lower splint 5 and the upper splint 6, and a spacing adjustment part is provided between the lower splint 5 and the support frame 1.

[0033] like Figure 1-Figure 3 As described above, the two long sides of the wire mesh 10 are clamped by the lower clamping plate 5 and the upper clamping plate 6 to achieve the effect of fixing the wire mesh 10 on the through groove 3.

[0034] To further optimize the solution, the locking part includes a slot 15 opened downward at both ends of the top of the lower splint 5 and an insertion rod 14 fixedly connected to the two ends of the bottom of the upper splint 6. The two groups of insertion rods 14 are respectively fixedly connected with a lower wedge plate 12, and the side walls of the two groups of slots 15 are respectively fixedly connected with an upper wedge plate 11. The lower wedge plate 12 is arranged corresponding to the upper wedge plate 11, and an unlocking part is also provided between the insertion rod 14 and the slot 15.

[0035] like Figure 4 As shown, in order to ensure the effectiveness of the lower clamping plate 5 and the upper clamping plate 6 in clamping the wire mesh 10, when the upper clamping plate 6 rotates around the rotating shaft 7 toward the lower clamping plate 5 and cooperates with the lower clamping plate 5 to bite the wire mesh 10, the insertion rod 14 extends into the slot 15 and drives the lower wedge plate 12 to move downward along the inclined surface of the upper wedge plate 11 until the top plane of the lower wedge plate 12 contacts the bottom plane of the upper wedge plate 11, locking the upper clamping plate 6, so that the upper clamping plate 6 and the lower clamping plate 5 can firmly bite the wire mesh 10.

[0036] To further optimize the solution, the spacing adjustment member includes a baffle 9 fixedly connected to the middle of the edge of the support frame 1, and a bolt 8 is rotatably connected to the baffle 9, and the threaded end of the bolt 8 is transmission-connected to the side wall of the lower clamping plate 5 away from the through groove 3.

[0037] To further optimize the solution, two groups of slide grooves 4 are provided on the top of the support frame 1, and the two groups of slide grooves 4 are respectively located at the two ends of the through groove 3, and the two groups of slide grooves 4 are perpendicular to the length direction of the lower splint 5, and the two ends of the lower splint 5 are respectively slidably connected in the two groups of slide grooves 4.

[0038] like Figure 2 As shown, a threaded hole (not shown) is provided in the middle of the side wall of the lower clamping plate 5, which is adapted to the threaded end of the bolt 8. After the two long sides of the screen 10 are clamped between the two lower clamping plates 5 and the upper clamping plate 6, respectively, to ensure the printing effect, the screen 10 needs to be flattened and maintained at a certain tension. At this time, the operator rotates the two sets of bolts 8, and the transmission between the threaded ends of the bolts 8 and the threaded holes causes the two lower clamping plates 5 to move outward, thereby flattening the screen 10.

[0039] As a further optimization solution, a plurality of engaging teeth 16 are fixedly connected to the top of the lower splint 5 and the bottom of the upper splint 6 on the side away from the rotating shaft 7 along the length direction of the lower splint 5 and the upper splint 6, respectively, and the plurality of engaging teeth 16 are arranged corresponding to the wire mesh 10.

[0040] like Figure 4 As shown, the main function of the engaging teeth 16 is to ensure that the screen 10 does not fall off during the printing process.

[0041] A further optimized solution is that the unlocking part includes an extrusion column 13 horizontally slidably connected to the lower splint 5, one end of the extrusion column 13 is located on the outside of the lower splint 5, and the other end of the extrusion column 13 is located on the inside of the slot 15, and the other end of the extrusion column 13 is in contact with the side wall of the insertion rod 14 close to the lower wedge plate 12.

[0042] like Figure 4 As shown, when the screen 10 needs to be removed after the printing operation is completed, the operator can press the squeezing column 13 inward so that the squeezing column 13 squeezes the insertion rod 14 inward, thereby forcing the lower wedge plate 12 to separate from the upper wedge plate 11, thereby opening the upper clamping plate 6.

[0043] To further optimize the solution, the squeegee clamp 17 can be driven by appropriate machinery and equipment to move horizontally, achieving a scraping and pressing effect, saving manpower and improving work efficiency. Furthermore, to ensure that the support frame 1 remains in position during the printing process, the laboratory can add corresponding stoppers and other structures to the machinery and equipment to block and restrict the movement of the support frame 1. Stoppers are common structures in the field and will not be described in detail.

[0044] The working process of this embodiment is as follows: ╳ Taking a 100mm cell as an example, a film of a specified size is placed in a fixed position on the screen 10 and exposed to light until the width of the gaps between the two cells are the same as the spacing between the cells. As shown in the figure, the cells are placed on a dedicated holder and first printed with peelable adhesive in the horizontal direction. Specifically, the two sides of the screen 10 are clamped between the upper and lower clamping plates 6 and 5, and the bolts 8 are adjusted to flatten the screen 10 and ensure that the gaps in the printed area are within the through-slots 3. The support frame 1 is fixed on the cell, ensuring that the gaps in the printed area on the screen 10 correspond to the gaps in the horizontal direction between the cells. The shaped scrapers 18 are also positioned to correspond to the gaps in the printed area on the screen 10. After adding the peelable adhesive to the screen 10, the equipment is started to drive the scraper clamp 17 to move horizontally to scrape and press the screen 10. Since the special-shaped scraper 18 only corresponds to the battery gap, during scraping and pressing, the special-shaped scraper 18 only presses down the screen 10, so that the unprinted area on the screen 10 contacts the gap between the battery cells on the substrate, and does not contact the battery cells. Therefore, the battery cells can be protected from pressure, and at the same time, the peelable adhesive is printed on the horizontal gap between the two battery cells on the substrate under pressure.

[0045] After that, rotate the substrate and re-place the support frame 1. Print the peelable glue in the longitudinal gap of the battery sheet according to the above principle to complete the printing work. The effect is as follows: Figure 7 shown.

[0046] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0047] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
