[0038] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0039] Currently, in the solar photovoltaic field, substrate frames are typically constructed using materials such as steel plates and aluminum alloy plates. When the substrate is heated, radiant heat is directly conducted to the substrate frame, causing its temperature to rise. However, existing substrate frames lack effective heat insulation measures, making them prone to bending and deformation due to high temperatures after prolonged use. Furthermore, the surface of the substrate frame is easily covered by a film layer, affecting its normal use. Existing technology suffers from the following problems: due to the lack of protective measures, directly spliced ​​substrate frames are prone to thermal deformation in high-temperature environments, which not only affects their normal use but can also lead to permanent deformation or direct damage in severe cases. Simultaneously, the surface of directly spliced ​​substrate frames is easily covered by a film layer, requiring frequent replacement and cleaning maintenance, thus shortening the lifespan of the substrate frame and the maintenance cycle accordingly.

[0040] To address the aforementioned problems, this invention proposes a novel substrate holder that better adapts to high-temperature environments, effectively preventing significant deformation caused by high temperatures and thus avoiding any impact on its use or damage. Furthermore, this substrate holder eliminates the need for frequent replacement and is easy to clean and maintain.

[0041] like Figure 1 As shown, the substrate holder proposed in this utility model includes:

[0042] The support frame 1 has a front and a back facing opposite each other, and at least one substrate placement area 13 extending through the front and back faces, wherein the front face of the support frame 1 faces the same direction as the substrate surface to be coated.

[0043] The protective component 2 is provided at least on the front side of the support frame 1 to prevent heat from being directly radiated to the support frame 1 during the coating process and to prevent the film layer from directly covering the support frame 1.

[0044] This invention employs a protective component 2 added to the support frame 1. This protective component 2 effectively blocks radiant heat, preventing the support frame 1 from undergoing severe deformation due to excessive temperature, thereby avoiding affecting the normal use of the substrate holder or causing damage to it. Furthermore, this protective component 2 also prevents the film layer from excessively covering the support frame 1, thus extending the cleaning and maintenance cycle and service life of the substrate holder.

[0045] In some embodiments of this utility model, such as Figure 1 , Figure 4 , Figure 5 As shown, the support frame 1 includes multiple support horizontal plates 10 and multiple support vertical plates 11 that together form at least one substrate placement area 13; the protective component 2 includes multiple protective horizontal plate groups and multiple first protective vertical plate groups; multiple protective horizontal plates 21 in each protective horizontal plate group are spaced apart on the front of the support horizontal plate 10, and adjacent two protective horizontal plates 21 are connected by a connecting plate 24; multiple first protective vertical plates 22 in each first protective vertical plate group are spaced apart on the front of the support vertical plate 11, and adjacent two first protective vertical plates 22 are connected by a connecting plate 24.

[0046] This invention achieves full coverage of the front of the support frame 1 by adding a protective horizontal plate group to the front of the support horizontal plate 10 and a first protective vertical plate group to the front of the support vertical plate 11. Simultaneously, the arrangement of the protective components 2 ensures that the substrate placement area 13 is not obstructed, thus avoiding adverse effects on the coating process. Furthermore, the various protective plates in the protective components 2 (including the protective horizontal plate 21 and the first protective vertical plate 22) adopt a multi-segment splicing design to prevent the entire protective plate from excessively elongating and warping due to thermal expansion. For large substrate holders, the entire protective plate is not only large in size and heavy, but also very inconvenient to assemble and disassemble. While space is reserved between adjacent protective plates to allow them to stretch freely under high temperatures, this reserved space easily accumulates dust during the coating process. To achieve a dustproof effect, the protective plates are connected to each other by connecting plates 24, and a cross-stacked method is used at the splicing points to prevent dust from falling into the support frame 1 through the gaps between the two protective plates.

[0047] It should be noted that the number of substrate placement areas 13 in the support frame 1 can be flexibly adjusted according to actual needs, and no specific restrictions are imposed in this paper. For ease of explanation, the following will be illustrated using an example where the support frame 1 has two substrate placement areas 13.

[0048] like Figure 1As shown, the support frame 1 is composed of two support horizontal plates 10 (upper support horizontal plate 101 and lower support horizontal plate 102) and three support vertical plates 11 (left support vertical plate 111, middle support vertical plate 112 and right support vertical plate 113), which together form two substrate placement areas 13.

[0049] like Figure 1 , Figures 11 to 13 As shown, a first protective longitudinal plate 22 and a second protective longitudinal plate 23 are added to the front and back of a portion of the supporting longitudinal plate 11, respectively. Specifically, the left supporting longitudinal plate 111 and the right supporting longitudinal plate 113 have a first protective longitudinal plate group and a second protective longitudinal plate group on their front and back sides, respectively. The first protective longitudinal plate group is composed of four first protective longitudinal plates 22 spliced ​​together, and the second protective longitudinal plate group is composed of four second protective longitudinal plates 23 spliced ​​together. The first protective longitudinal plate 22 on the left supporting longitudinal plate 111 is connected to the corresponding second protective longitudinal plate 23 by a ramp 25, and the first protective longitudinal plate 22 on the right supporting longitudinal plate 113 is connected to the corresponding second protective longitudinal plate 23 by a ramp 25. It should be understood that in the coating chamber, adjacent substrate holders are in close contact and coating is performed at a uniform speed. During the coating process, the film layer may be deposited onto the other side of the substrate holder through the gaps between adjacent substrate holders. The first protective longitudinal plate 22 and the corresponding second protective longitudinal plate 23 on the left support longitudinal plate 111 and the right support longitudinal plate 113 are connected by a ramp 25, which not only facilitates the tracking of the front and rear substrate holders but also helps to reduce the occurrence of wrap-around plating. It also facilitates the installation of two types of protective plates (the first protective longitudinal plate 22 and the second protective longitudinal plate 23) on the left support longitudinal plate 111 and the right support longitudinal plate 113. Furthermore, this design eliminates the need to add fasteners to the sides of the left support longitudinal plate 111 and the right support longitudinal plate 113.

[0050] In addition, the front of the intermediate support longitudinal plate 112 is provided with a first protective longitudinal plate group, which is composed of four first protective longitudinal plates 22 spliced ​​together. At the same time, the front of the two support transverse plates 10 is provided with a protective transverse plate group, which is composed of four protective transverse plates 21 spliced ​​together.

[0051] It should be noted that, as Figure 1 , Figure 2 and Figure 12 As shown, various protective plates (including protective horizontal plates 21, first protective vertical plates 22, and second protective vertical plates 23) can be installed on the support frame 1 using multiple first fastening components 3 or second fastening components 4. Among them, the structure of the second fastening component 4 is simpler than that of the first fastening component 3, and its installation is also more convenient.

[0052] In a preferred embodiment of this utility model, the protective horizontal plate 21 is mounted on the supporting horizontal plate 10 by four first fastening components 3, and the first protective vertical plate 22 is mounted on the supporting vertical plate 11 by three first fastening components 3. The protective horizontal plate 21 has four mounting holes 20 for inserting the four first fastening components 3, of which three mounting holes 20 are oblong holes and one mounting hole 20 is a circular hole. The first protective vertical plate 22 has three mounting holes 20 for inserting the three first fastening components 3, of which two mounting holes 20 are oblong holes and one mounting hole 20 is a circular hole. When the mounting holes 20 of various protective plates (including the protective horizontal plate 21 and the first protective vertical plate 22) are circular holes, their function is to position the protective plates and prevent them from shifting; while when the mounting holes 20 are oblong holes, it is to reserve installation space and thermal expansion space, which facilitates the installation of the protective plates and prevents the protective plates from bulging due to insufficient expansion after being heated.

[0053] like Figures 2 to 10 As shown, taking the installation of the first protective longitudinal plate 22 as an example, the first fastening component 3 includes an isolation fastener 30 and a support column 31. The isolation fastener 30 has a plug-in column 301, a snap-fit ​​connector 302, and a through hole 303 penetrating the plug-in column 301 and the snap-fit ​​connector 302. The plug-in column 301 extends into the fixing hole of the supporting longitudinal plate 11, and the bottom of the snap-fit ​​connector 302 abuts against the front of the supporting longitudinal plate 11. The support column 31 has a connecting column 311 and a support head 312. The connecting column 311 extends into the through hole 303 of the isolation fastener 30. The first protective longitudinal plate 22 is sleeved on the side of the support head 312 and abuts against the top of the snap-fit ​​connector 302. This design can form a certain gap between the first protective longitudinal plate 22 and the supporting longitudinal plate 11, thereby effectively preventing the heat from the heater during the coating process from directly radiating to the supporting longitudinal plate 11, and also reducing the possibility of heat being conducted from the first protective longitudinal plate 22 to the supporting longitudinal plate 11.

[0054] In this isolation fastener 30, the snap-fit ​​connector 302 can be designed in an external hexagonal shape for easy installation and disassembly. The outer side of the plug-in post 301 has external threads for locking into the fixing hole of the supporting longitudinal plate 11, while the inner side of the through hole 303 has internal threads for installing and fixing the support column 31. The connection between the plug-in post 301 and the snap-fit ​​connector 302 has a groove 304, and the fixing hole of the supporting longitudinal plate 11 has a protrusion that matches the groove 304; this design ensures that after the plug-in post 301 is fixed in the fixing hole of the supporting longitudinal plate 11, the isolation fastener 30 can be stably fastened to the supporting longitudinal plate 11. Furthermore, the isolation fastener 30 is made of heat-insulating and high-temperature-resistant material to reduce heat conduction from the first protective longitudinal plate 22 to the supporting longitudinal plate 11.

[0055] In the support column 31, the outer side of the connecting column 311 is provided with external threads for fixing with the through hole 303 of the isolation fastener 30. The support head 312 can be designed as a cylinder, serving as a support column for the first protective longitudinal plate 22, which is suspended from the support head 312 through the mounting hole 20. The support column 31 can be made of a material with high rigidity to better support the weight of the first protective longitudinal plate 22. In addition, the support head 312 is provided with a slot 313. After the first protective longitudinal plate 22 is suspended and installed, a retaining spring 32 is inserted into the slot 313 to prevent the first protective longitudinal plate 22 from falling off.

[0056] like Figure 3 As shown, the first protective longitudinal plate 22 is suspended between the snap-fit ​​connector 302 and the snap ring 32. The snap-fit ​​connector 302 separates the first protective longitudinal plate 22 from the supporting longitudinal plate 11, maintaining a certain gap between them, thereby reducing heat conduction from the first protective longitudinal plate 22 to the supporting longitudinal plate 11. The snap ring 32 prevents the first protective longitudinal plate 22 from falling off, while also preventing it from being directly pressed, allowing it to stretch freely after being heated. When the substrate holder needs cleaning and maintenance, simply remove the snap ring 32, remove the first protective longitudinal plate 22 for cleaning, and replace it with a new one. Of course, in other optional embodiments, the support head 312 is provided with a pin hole, into which a pin is inserted to prevent the first protective longitudinal plate 22 from falling off. The pin has a similar function to the snap ring 32, and will not be described further here. Alternatively, the snap ring 32 or the pin can be omitted, and an anti-detachment protrusion can be provided on the support head 312, with its maximum width being greater than the diameter of the mounting hole 20 of the first protective longitudinal plate 22, which can also play the role of preventing detachment.

[0057] In the preferred embodiment of this utility model, such as Figure 12 As shown, the second protective longitudinal plate 23 is mounted on the supporting longitudinal plate 11 via two second fastening components 4. Each second fastening component 4 includes a clamping member 40 and an isolation gasket 41. The clamping member 40 has a fixing post and a pressure joint. The fixing post extends into a fixing hole in the supporting longitudinal plate 11. The isolation gasket 41 is fitted onto the side of the fixing post and abuts against the back of the supporting longitudinal plate 11. The isolation gasket 41 and the pressure joint abut against both sides of the supporting longitudinal plate 11. This design creates a certain gap between the second protective longitudinal plate 23 and the supporting longitudinal plate 11, thereby effectively reducing the possibility of heat being conducted from the second protective longitudinal plate 23 to the supporting longitudinal plate 11.

[0058] The substrate holder proposed in this invention effectively blocks radiant heat and prevents the support frame surface from being covered by a film layer by adding protective components to the support frame. Furthermore, when certain protective plates in the protective components are fixedly connected to the support frame, isolation fasteners made of heat-insulating and high-temperature-resistant materials are used, while ensuring a certain distance is maintained between the protective plates and the support frame, thereby reducing the possibility of heat conduction to the support frame. At the same time, the arrangement and installation of the protective components do not significantly affect the overall dimensions of the support frame, avoiding any impact on the overall design of the cavity. In addition, the disassembly and assembly of the protective components are simple and easy.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
