Description

Technical Field

[0001] This invention belongs to the field of semiconductor device technology under IPC classification H01L31 / 00, which is sensitive to infrared radiation, light, short-wavelength electromagnetic radiation, or particle radiation, and is specifically applicable to converting such radiation energy into electrical energy, or specifically applicable to electrical energy control through such radiation. In particular, it relates to an auxiliary tooling technology that is especially applicable to the manufacturing or handling of solar cell mounting and positioning. Background Technology

[0002] The design reasons for the spacing of solar cell patches mainly include the following aspects:

[0003] Voltage Requirements: The spacing between solar cells is to meet the voltage requirements of the solar panel. For example, the voltage of a monocrystalline or polycrystalline silicon cell is about 0.5V. If a 12V solar panel is required, 24 cells are needed. Therefore, a certain gap needs to be left between the cells to avoid short circuits when welding the copper strips between the cells.

[0004] Avoiding short circuits and aesthetics: The spacing between the solar cells can prevent short circuits during the welding process, and also make the solar panel look more aesthetically pleasing.

[0005] Power and Material: The spacing between solar cells depends on the power output of the solar panel. Higher power requires larger cell spacing, and vice versa. Furthermore, the surface material of the solar panel also affects the margin. For example, if glass lamination is used, the cells are prone to shifting, resulting in a larger margin; while using PET material results in a smaller margin.

[0006] Frame material: The frame material also affects the margin distance. Aluminum alloy frames have a larger margin than plastic frames, while frameless frames have the smallest margin.

[0007] The solar panels used on my country's space station are a new generation of flexible solar arrays. These consist of ultra-thin, lightweight composite material panels covered with triple-junction gallium arsenide solar cells, achieving a photoelectric conversion efficiency of 30%, far exceeding the International Space Station's 15%. The solar cells on satellite solar panels also utilize the same technological requirements. This is especially true for the rapidly developing perovskite solar cell products.

[0008] Perovskite solar panels, a type of perovskite solar cell, utilize perovskite-type organometal halide semiconductors as light-absorbing materials. Perovskite solar panels typically consist of a multi-layered thin-film structure, including conductive glass, a perovskite thin film, an electrolyte, and electrodes. Perovskite solar panels boast conversion efficiencies exceeding 20%, far surpassing traditional silicon-based solar panels. Some advanced perovskite solar cells have even achieved conversion efficiencies exceeding 26%, and with tandem layering techniques, their theoretical maximum conversion efficiency can reach 33% or higher. The perovskite thin film is the core component of the entire solar panel, converting light energy into electrical energy. Perovskite solar panels can utilize transparent flexible panels, requiring enhanced encapsulation technology.

[0009] Currently, in the field of solar cell fabrication on satellite solar panels, to adapt to various working conditions, the process of attaching perovskite solar cells of different sizes to solar panels and perovskite solar cells is mainly done manually. This inevitably leads to significant errors in manually controlling the spacing and positioning of the parallel arrangement of solar cell patches. In parallel solar arrays, the actual standard gap between adjacent cells, i.e., the gap width between the functional layers of two cells, is required to be 1mm. To ensure the safety of the solar cell functional layers, a glass cover is sealed on the outermost surface. The outermost glass cover of the solar cell is 0.05mm larger on each side than the functional layer, ensuring a parallel gap width of 0.9mm between the two solar cells (i.e., the gap width of the glass cover). Therefore, relying solely on the existing common method of manually measuring dimensions and manually attaching the cells easily leads to gaps in the parallel arrangement and may even increase system errors.

[0010] Through research and analysis, similar solutions were found in some related fields, including:

[0011] Patent application 201010556586.1 discloses a laying fixture for assembling solar cell modules, comprising two positioning clamps, a ruler, and multiple positioning clips. The ruler is connected between the two positioning clamps, and the multiple positioning clips are movably connected to the ruler and can be adjusted left and right.

[0012] This type of auxiliary technology, which aims for a neat appearance and quick installation, is suitable for the early preparation of monocrystalline silicon solar photovoltaic panels. However, its application value is limited due to the stringent technical standards required for the current stage of the development of second-generation polycrystalline silicon and amorphous silicon solar cells to third-generation solar cells, which are mainly compound thin-film solar cells such as copper indium gallium selenide (CIGS) and perovskite solar cells.

[0013] Patent application 201811357415.9 discloses a method for attaching a flexible array solar cell module to a substrate for space applications. This method includes: Step 1, fixing the solar cell module to a module transfer fixture; Step 2, fixing the flexible array panel to a base plate positioning fixture; Step 3, applying adhesive to the flexible array panel; Step 4, fixing the solar cell module, along with the module transfer fixture, to the base plate positioning fixture; Step 5, pre-pressing the solar cell module using an airbag; and Step 6, laminating the solar cell module using a laminator. Additionally, patent application 202410066351.6 discloses a manufacturing process for a space solar cell array, including module welding, silver bar welding, module cleaning, coating the back of the module with adhesive, and module fabrication. After the components are welded, they are transferred by a robotic arm to a silver bar welding equipment to attach the first transparent film and complete the silver bar welding. Manual work, component flipping, second transparent film attachment, and component stacking are performed on the first conveyor belt. The components are then transferred by an AGV trolley to a storage cabinet for temporary storage. The material sorting mechanism separates the components. The second transparent film is removed on the second conveyor belt, and the components are attached to the tooling. The first transparent film is removed on the third conveyor belt, and the backlight side is cleaned. The adhesive coating equipment completes the application of adhesive to the back of the components. The fabrication equipment flips the components and attaches them to the canvas. The component tooling is then conveyed to the front-end for production preparation via the third conveyor belt.

[0014] The method for attaching flexible array solar cell modules to the upper plate provided by this type of solution is relatively complete, but it is not suitable for manual or semi-manual operation. Utility Model Content

[0039] It should be noted that:

[0043] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0045] Aerospace solar cells are prone to damage; please refer to the attached document. Figure 1 As shown, when pasting the solar cells 8 onto the surface of the solar panel 7 before encapsulation, it is necessary to maintain the accurate positioning of adjacent solar cells 8. This requires ensuring the accuracy of the parallel gap, i.e., the film spacing S, and also protecting the solar cells from damage during the pasting process. This tooling can precisely control the parallel gap, making the solar cells less prone to damage, and can also effectively reduce the damage to the polyimide film on the surface of the solar panel due to friction.

[0046] This utility model includes a grooved rail half-support 1, a ridge rail half-support 2, and a grid plate 3; the grooved rail half-support 1 and the ridge rail half-support 2 are mutually telescopically slidably connected by a sliding groove 4 and a raised ridge 5 provided thereon, and vertical slots 6 are provided on opposite sides of the inner wall of the grooved rail half-support 1 or the ridge rail half-support 2, with the grid plate 3 inserted between them.

[0047] The principle of this utility model is that the total length of the groove rail half bracket 1 and the ridge rail half bracket 2 can be adjusted by stretching or retracting. At the same time, the spacing between adjacent baffles 3 can be adjusted at different slot 6 positions to accommodate different sizes and specifications of sails 7 and battery cells 8.

[0048] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0049] Example 1: As shown in the attached document Figure 2 , 3 As shown in Figures 5, 6, 7, and 8, this tooling comprises three parts: a channel rail half-support 1, a ridge rail half-support 2, and a grid plate 3. The channel rail half-support 1 and the ridge rail half-support 2 have a U-shaped structure. One end of a pair of parallel and symmetrically placed channel beams 11 on the channel rail half-support 1 is connected by a channel connecting beam 12, and one end of a pair of parallel and symmetrically placed ridge beams 21 on the ridge rail half-support 2 is connected by a ridge connecting beam 22. An upward-opening sliding groove 4 is provided on the inner side of the upper side of the channel beam 11. A downward-protruding ridge 5 is provided on the middle of the lower side of the ridge beam 21. The two pairs of long beam structures of the channel rail half-support 1 and the ridge rail half-support 2, the channel beams 11 and ridge beams 21, are slidably engaged with each other through the sliding grooves 4 and ridges 5. Furthermore, a slot 6 is provided on the inner wall of either the channel beam 11 or the ridge beam 21. A grid plate 3 is inserted into the slot 6 on the corresponding inner walls of the channel rail half-support 1 and the ridge rail half-support 2.

[0050] As mentioned above, support legs are respectively provided at the bottom of the outer corners of the trough rail half-support 1 and the ridge rail half-support 2. That is, the bottom of the outer corners of the trough rail half-support 1 is respectively provided with the first support leg 13, and the bottom of the outer corners of the ridge rail half-support 2 is respectively provided with the second support leg 23.

[0051] In this embodiment of the utility model, further, preferably, as shown in the appendix Figure 4 As shown, the slide 4 is a straight groove with a uniform cross-section and a dovetail groove structure with a large inner belly and a small opening. The ridge 5 is a straight I-beam structure with a uniform cross-section. The average width of the lower part of the ridge 5 is greater than that of the middle part. The slide 4 has a limiting effect on the ridge 5. The slide 4 and the ridge 5 can only be connected or unlocked by interlocking along the axial direction.

[0052] In this embodiment of the present invention, more preferably, after the slide groove 4 and the ridge 5 are fully inserted, they are flush with the inner walls of the groove rail half-support 1 and the ridge rail half-support 2, that is, the inner walls of the groove beam 11 and the ridge beam 21.

[0053] In this embodiment of the present invention, more preferably, after the sliding groove 4 and the ridge 5 are fully inserted, the upper and lower sets of slots 6 on the inner sidewalls of the groove rail half-support 1 and the ridge rail half-support 2, that is, the inner wall of the groove beam 11 or the ridge beam 21, are aligned. At the same time, further, that is, after the grid plate 3 is inserted into the slot 6, the relative positions of the groove rail half-support 1 and the ridge rail half-support 2 are relatively locked.

[0054] In this embodiment of the present invention, preferably, the width of the half-support 1 and the half-support 2 of the spur rail is 163mm, the length of the half-support 1 and the half-support 2 of the spur rail is 510mm, and the height of the first leg 13 and the second leg 23 is 40mm. The spur beam 11 is 501mm long, and the spur beam 21 is 500mm long; the spur beam 11 and the spur beam 21 are 13mm wide and 10mm high; the slot 6 is 1mm wide and 3mm deep; the opening width of the slide 4 is 4mm; and the baffle plate 3 is 143mm long and 0.9mm thick. The surface of the sail 7 is originally covered with a polyimide film to prevent metal from scratching the polyimide film. The baffle plate 3 is made of resin material, and the hardness of resin is much lower than that of metal, so it causes almost no damage to the polyimide film.

[0055] The implementation principle of this embodiment is as follows: the width of the slot 6 is 1mm, the thickness of the baffle plate 3 is 0.9mm, with a margin of 0.1mm to facilitate baffle replacement, and the depth of the slot 6 is 3mm. When the sliding groove 4 and the ridge 5 are slidably inserted and connected, according to the required specifications and dimensions of the corresponding sail plate 7 and battery cell 8, the groove rail half bracket 1 and the ridge rail half bracket 2 are kept in a mutually stretched position, and the upper and lower sets of slots 6 are aligned. The baffle plate 3 is then placed in, and the entire fixture is fixed.

[0056] Furthermore, in order to better distinguish and apply the corresponding size of each type of solar cell 8, the slots 6 can be grouped, and the slots 6 in different groups can be marked with different corresponding colors. For example, when pasting 4*8 size solar cells, the baffle 3 is installed in the corresponding blue slot 6; when pasting 4*6 size solar cells, the baffle 3 is installed in the corresponding green slot 6; and when pasting 3*4 size solar cells, the baffle 3 is installed in the corresponding red slot 6.

[0057] In application, the first leg 13 and second leg 23 of the support pillars of the channel rail half-support 1 and the ridge rail half-support 2 are placed on the operable platform, and the attached solar panel 7 is placed on the middle bottom surface of the channel rail half-support 1 and the ridge rail half-support 2. The relative positions of the channel rail half-support 1 and the ridge rail half-support 2 are adjusted according to the size of the solar panel 7 to adapt to the width of the solar panel 7, and the upper and lower sets of slots 6 to be used are aligned. After the baffle plate 3 is installed on the slot 6, the channel rail half-support 1 and the ridge rail half-support 2 are fixed and will not move left or right. The bottom of the baffle plate 3 is stably attached to the solar panel 7. When attaching the solar cell 8 to the solar panel 7, it is only necessary to attach the solar cell 8 between the two pre-set adjacent baffle plates 3 to ensure that the spacing between the solar cell glass covers assembled later is accurately 0.9mm.

[0058] In this embodiment of the invention, the fixture can not only effectively handle perovskite solar cells of different sizes, but also triple-junction gallium arsenide solar cells, monocrystalline silicon solar cells, polycrystalline silicon solar cells, etc., ensuring that the parallel gap of the cell array is strictly and accurately controlled within 0.9mm; it can also adapt to the bonding limit of solar cells of various sizes and specifications by adjusting the size of the slot 6 on the fixture and the film spacing S, i.e., the spacing width; in addition, the fixture can be easily extended and adjusted to adapt to different sizes of solar panels, demonstrating the adaptability of the fixture.

[0059] Example 2: As shown in the attached document Figure 9 As shown, the chute 4 and the ridge 5 are set on the side wall of the chute beam 11 or the ridge beam 21 of the chute rail half support 1 and the ridge rail half support 2.

[0060] As mentioned above, a sliding groove 4 is provided on the side wall of the channel beam 1 of the channel rail half-support 1, and correspondingly, a convex ridge 5 is provided on the side wall of the ridge beam 21 of the ridge rail half-support 2. The sliding groove 4 and the convex ridge 5 are slidably engaged in a straight direction.

[0061] Preferably, the mating cross-section of the groove 4 and the ridge 5 includes a rectangle, a triangle, a trapezoid, an arc, or an inverted triangle structure.

[0062] In this embodiment of the invention, under its own weight, the relative sliding of the groove 4 and the ridge 5 requires overcoming a large frictional force. Furthermore, the implementation principle is as follows: the slot 6 only needs to be set on the inner side wall of the channel beam 11 or the ridge beam 21 in the channel rail half-support 1 or the ridge rail half-support 2. It does not require the upper and lower sets of slots 6 to be aligned as in embodiment 1. However, at the same time, a locking mechanism is required to fix the mutual extension and retraction positions of the channel rail half-support 1 and the ridge rail half-support 2.

[0063] Example 3: As shown in the attached document Figure 10 As shown, based on embodiment 2, at least one set of roller 9 structures is further provided in the upper or lower mating surfaces of the sliding groove 4 and the ridge 5 to improve the smoothness and convenience of relative sliding between the groove rail half-support 1 and the ridge rail half-support 2.

[0064] Preferably, a vibration damping pad 10 is provided at the bottom of the slide 4 to further improve the sliding effect and reduce working noise.

[0065] This utility model can also be implemented in various ways, including: the matching structure of the sliding groove 4 and the ridge 5, the upper and lower positional arrangement of the sliding groove 4 and the ridge 5, and the structure or shape of the support leg.

[0066] Based on the embodiments of this utility model described above, all other embodiments obtained by those skilled in the art without inventive effort should fall within the scope of protection of this utility model. This is to avoid exhaustively listing all possible implementation methods that are neither necessary nor feasible to fully enumerate.
