Technical Field

[0001] This utility model relates to the field of coating carrier technology, and in particular to a solar cell vapor deposition fixture. Background Technology

[0002] Vacuum evaporation coating refers to a technique that uses a vacuum source to heat and evaporate a substance, causing it to deposit onto the surface of a substrate material to form a thin film. To improve the absorption capacity of solar cells for solar radiation and increase their efficiency in converting light energy, solar cells are typically subjected to evaporation coating to form a thin film of materials such as magnesium fluoride, silicon oxide, silver, or nickel on their surface.

[0003] The vapor deposition of solar cells requires appropriate vapor deposition equipment. However, current solar cell vapor deposition equipment can usually only perform single-sided deposition on solar cells after installation. Furthermore, during the deposition process, high-temperature tape is required to protect the metal grid lines of the solar cells manually, which results in high labor costs.

[0004] Based on this, the present invention proposes a solar cell vapor deposition fixture to solve the problems mentioned above. Utility Model Content

[0007] Both of the clamping plates have a through-hole groove on their end faces, and both of the clamping plates have a one-way protective grille in their grooves.

[0008] When the two clamping plates are engaged, the placement slots of the two clamping plates are joined together to form a placement cavity for accommodating solar cells;

[0009] When the solar cell is placed in the placement cavity, the unidirectional protective grilles in the placement slots of the two clamps are respectively attached to and completely cover the metal grid lines on both ends of the solar cell.

[0010] Furthermore, one end face of one of the clamping plates is provided with a positioning groove at the periphery of its placement slot, and one end face of the other clamping plate is provided with a positioning boss that matches the positioning groove at the periphery of its placement slot.

[0011] Furthermore, multiple fixing holes are provided at corresponding positions on the two end faces of the clamps.

[0012] Further, the fixing hole adopts a countersunk hole.

[0013] Further, the one-way protection grid comprises a plurality of protection strips, and a plurality of groups of the protection strips are parallel and equidistantly distributed.

[0014] Further, the solar cell evaporation tool further comprises a base; the base is in a cylindrical structure; one end of the base is internally provided with a fixing groove for placing two clamping plates; and a plasma inlet is formed in the sidewall of the base for allowing plasma to pass through.

[0015] Further, one of the two clamping plates is provided with a lifting handle.

[0016] Further, both sides of the end of the base away from the fixing groove are provided with a rotating hanging opening for hanging the base.

[0017] Compared with the prior art, the solar cell evaporation tool has at least the following beneficial effects:

[0018] The solar cell evaporation tool can realize the exposure of the double sides of the solar cell except the area of the metal grid lines, and based on this, when evaporation is performed, the solar cell evaporation tool is positioned and placed in the evaporation equipment, so that the double sides of the solar cell can be simultaneously coated, and the manual use of high-temperature adhesive tape for pasting and protecting the metal grid lines of the solar cell is not needed, thereby effectively reducing the labor cost.

[0025] The solar cell vapor deposition fixture of this invention will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the invention.

[0026] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0027] like Figure 1 As shown in the figure, this embodiment proposes a solar cell vapor deposition fixture, including two mating clamps 1. Each of the two clamps 1 has a placement groove 11 through its end face, and each of the two clamps 1 has a one-way protective grid 2 in its placement groove 11.

[0028] Specifically, refer to Figure 2 When the two clamping plates 1 are engaged, the placement slots 11 of the two clamping plates 1 are joined together to form a placement cavity 12 for accommodating solar cells;

[0029] When the solar cell is placed in the placement cavity 12, the one-way protective grilles 2 in the placement slots 11 of the two clamps are respectively attached to and completely cover the metal grid lines on both ends of the solar cell.

[0030] In the above embodiment, before the solar cell is vapor-deposited, the solar cell is first placed in the placement groove 11 of a clamping plate 1, then the placement groove 11 of another clamping plate 1 is aligned with the solar cell and the end faces of the two clamping plates 1 are made to fit together, and finally the two clamping plates 1 are fixed to realize the installation of the solar cell. The operation is simple.

[0031] After the solar cell is installed, since the one-way protective grating 2 is arranged in each of the two placing grooves 11, and the one-way protective grating 2 in each of the two placing grooves 11 respectively adheres to and completely covers the metal grid lines on the two end faces of the solar cell, the area of the installed solar cell except the metal grid lines on the two end faces can be exposed.

[0032] When the evaporation of the solar cell is performed, the fixed two clamping plates 1 are placed in the evaporation equipment, the area of the solar cell except the metal grid lines on the two end faces is exposed, so that the solar cell can be coated on both sides at the same time, and the metal grid lines on the two end faces of the solar cell are shielded by the one-way protective grating 2 on the clamping plate 1, without the need for manual use of high-temperature adhesive tape to paste and protect the metal grid lines of the solar cell.

[0033] In the above implementation process, the fixing between the two clamping plates 1 can be performed by penetrating a plurality of fixing holes 13 at the corresponding positions of the end faces of the two clamping plates 1, and fixing by penetrating the fixing holes 13 of the two clamping plates 1 with screws and cooperating with nuts.

[0034] Further, in order to improve the stability of the fixing of the two clamping plates by the screws and the nuts, the fixing holes 13 are provided as counter-sunk holes, and specifically, the fixing holes of one clamping plate are provided as tapered counter-sunk holes to match the corresponding counter-sunk screws, and the fixing holes of the other clamping plate are provided as hexagonal flat counter-sunk holes to match the corresponding hexagonal nuts.

[0035] In the above embodiment, it should be noted that a plurality of placing grooves 11 provided with the one-way protective grating 2 can be arranged on each clamping plate 1 to realize that a plurality of solar cells share one set of evaporation tooling.

[0036] The arrangement of the one-way protective grating 2 is determined according to the model of the solar cell. Specifically, the one-way protective grating 2 includes a plurality of protective strips, and a plurality of groups of protective strips are parallel and equidistantly distributed, the number of protective strips is consistent with the number of metal grid lines of the solar cell, and the spacing between adjacent protective strips is consistent with the spacing between adjacent metal grid lines of the solar cell.

[0037] In the above embodiment, one end face of one of the clamping plates 1 is provided with a positioning groove 14 (as shown in Figure 3 at the peripheral position of the placing groove 11 thereof, and one end face of the other clamping plate 1 is provided with a positioning boss 15 (as shown in Figure 4 ) matched with the positioning groove 14 at the peripheral position of the placing groove 11 thereof.

[0038] Through the arrangement of the positioning groove 14 and the positioning boss 15, the placing grooves 11 on the two clamping plates 1 are facilitated to be docked.

[0039] In one specific embodiment, to facilitate effective placement of the solar cell installed between the two clamping plates 1 in the evaporation equipment, the solar cell evaporation tool further comprises a base 3;

[0040] Specifically, the base 3 is a cylindrical structure; one end of the base 3 is provided with a fixing groove 31 for placing the two clamping plates 1; the sidewall of the base 3 is provided with a plasma inlet 32 for allowing plasma to pass through.

[0041] Preferably, after the clamping plate 1 is installed into the fixing groove 31, the sidewall of the clamping plate 1 is in close contact with the sidewall of the fixing groove 31, thereby ensuring stable installation of the clamping plate 1 and the base 3.

[0042] In the above specific embodiment, one of the two clamping plates 1 is provided with a lifting handle 4. Through the provision of the lifting handle 4, the clamping plate 1 installed in the fixing groove 11 can be easily taken out without the need for borrowing tools, and the operation is simple.

[0043] Further, both sides of the end of the base 3 away from the fixing groove 31 are provided with a rotating hanging hole 33 for hanging the base 3. Through the provision of the rotating hanging hole 33, stable hanging installation of the base 1 is achieved, and when disassembly is needed, the base 3 can be simply pushed up and then rotated, and no tools are needed.

[0044] Specifically, the rotating hanging hole 33 is in the shape of "J" and comprises an insertion groove 331 arranged along the length direction of the base 3, a transition groove 332 arranged along the circumferential direction of the base 3 and in communication with the insertion groove 331, and a stable groove 333 arranged at the end of the transition groove 332 away from the insertion groove 331. As shown in the figure, Figure 5 The stable groove 333 is arranged on the hanging rod 5, thereby achieving stable hanging installation of the base 3. When disassembly of the base 3 is needed, the base 3 is pushed up, the hanging rod 5 reaches the transition groove 332 region, and then the base 3 is rotated, so that the hanging rod 5 reaches the end of the insertion groove 331 along the transition groove 332, and the base 3 can be taken off from the hanging rod 5.

[0045] In summary, the solar cell evaporation tool provided by the utility model can realize external exposure of the area of the solar cell except the metal grid lines on both sides after installation of the solar cell, based on which, when evaporation is performed, the solar cell evaporation tool is positioned and placed in the evaporation equipment, thereby realizing simultaneous coating of both sides of the solar cell, and manual use of high-temperature adhesive tape for pasting and protection of the metal grid lines of the solar cell is not needed, thereby effectively reducing labor cost.

[0046] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
