[0002] Boat supports are critical load-bearing components in the diffusion process equipment of the photovoltaic industry. Common boat support materials used in the photovoltaic industry include quartz and silicon carbide. Traditional quartz boat supports have a relatively short lifespan, approximately 3-6 months, while silicon carbide boat supports can replace quartz boat supports, offering a much longer lifespan of over 5 years. Using silicon carbide boat supports can significantly reduce operating costs, minimize downtime due to maintenance and repairs, and reduce production capacity losses.

[0003] After the silicon carbide boat support is manufactured, workers need to use handheld spray guns to spray resin onto the surface of the silicon carbide boat support. Workers need to spray resin onto the inner and outer surfaces of the silicon carbide boat support in steps. The entire spraying operation involves a large amount of manual labor and the resin spraying efficiency of the silicon carbide boat support is low. Utility Model Content

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1 and Figure 2As shown in the embodiment of this application, a silicon carbide product resin spraying device is disclosed, comprising: a worktable for placing a silicon carbide boat support 1; a first pipe 21 disposed above the worktable along the outer contour of the silicon carbide boat support 1; a second pipe 22 disposed above the worktable along the inner contour of the silicon carbide boat support 1; a delivery pump 3 for delivering resin to the first pipe 21 and the second pipe 22; a plurality of nozzles 23 disposed on the first pipe 21 and the second pipe 22 for spraying resin; and a lifting assembly for supporting the worktable and capable of driving the worktable to rise and fall vertically, thereby moving the silicon carbide boat support 1 closer to / away from the nozzles 23.

[0021] In practical use, the silicon carbide boat 1 to be sprayed with resin is placed on the workbench, and the lifting assembly and the delivery pump 3 are started. The lifting assembly drives the workbench to rise vertically and moves the silicon carbide boat toward the nozzle 23. The delivery pump 3 delivers resin into the first pipe 21 and the second pipe 22. The nozzles 23 on the first pipe 21 and the second pipe 22 on both sides of the silicon carbide boat 1 can simultaneously perform resin spraying operations on the surface of the silicon carbide boat 1.

[0022] By using this invention, resin spraying can be performed on the inner and outer surfaces of the silicon carbide boat support 1, which can effectively reduce manual labor and improve the resin spraying efficiency of the silicon carbide boat support 1.

[0023] Specifically, the nozzle 23 is installed at a fixed angle to the horizontal plane. One end of the nozzle 23 is connected to the first pipe fitting 21 / the second pipe fitting 22, and the other end of the nozzle 23 faces the silicon carbide boat support 1. It is worth mentioning that the nozzle 23 can be installed on the first pipe fitting 21 and the second pipe fitting 22 by threaded connection. The inclined installation of the nozzle 23 can effectively increase the coverage area of ​​the sprayed resin and improve the resin spraying efficiency.

[0024] Specifically, the device also includes a cabin 4; the workbench, the first pipe 21 and the second pipe 22 are all located inside the cabin 4; the first pipe 21 and the second pipe 22 are suspended inside the cabin 4 by support rods; the spraying operation is carried out inside the cabin 4 to prevent resin splashing; of course, a hatch for the silicon carbide boat support 1 to be taken out and put in needs to be provided on the cabin 4.

[0025] Specifically, a number of nozzles 23 are arranged in an array at fixed intervals on the first pipe 21 and the second pipe 22 to improve the uniformity of resin spraying on the surface of the silicon carbide boat support 1.

[0026] In this embodiment, the workbench includes: a first tabletop 51 and a second tabletop 52. The first tabletop 51 is used to support both ends of the silicon carbide boat support 1, and the second tabletop 52 is used to support the middle section of the silicon carbide boat support 1. The lifting assembly includes: a first telescopic component 71 and a second telescopic component 72. The first telescopic component 71 is used to support the first tabletop 51, and the second telescopic component 72 is used to support the second tabletop 52.

[0027] In practical use, the first telescopic component 71 first extends and retracts once, which can drive the silicon carbide boat support 1 to move up and down in the vertical direction once, and the nozzle 23 sprays the surface of the silicon carbide boat support 1 once; then the second telescopic component 72 extends and retracts once, which can drive the silicon carbide boat support 1 to move up and down in the vertical direction once more, and the nozzle 23 sprays the surface of the silicon carbide boat support 1 a second time.

[0028] It is worth mentioning that both the first telescopic component 71 and the second telescopic component 72 can be hydraulic cylinders; by alternately driving the silicon carbide boat support 1 to perform lifting and lowering movements through the first telescopic component 71 and the second telescopic component 72, two resin spraying operations can be performed on the same silicon carbide boat support 1, and the surface of the silicon carbide boat support 1 that is covered by the first table 51 can be emptied and resin spraying operations can be performed to ensure the quality of resin spraying.

[0029] Specifically, the device also includes: a storage tank for storing resin, the storage tank being connected to the inlet of the conveying pump 3, and the outlet of the conveying pump 3 being connected to the first pipe fitting 21 and the second pipe fitting 22.

[0030] Reference Figure 3 As shown, the projections of the first pipe fitting 21 and the second pipe fitting 22 in the vertical direction are rectangles.

[0031] In this embodiment, the device further includes: an anti-slip pad 6 made of rubber, which is placed on the worktable for the silicon carbide boat support 1 to press against, thereby increasing the friction between the silicon carbide boat support 1 and the worktable, preventing the silicon carbide boat support 1 from sliding, and improving the stability during the lifting process.
