Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel production, in particular to a photovoltaic component appearance inspection flipping device. Background Art

[0002] Photovoltaic modules, also known as solar panels, can convert solar energy into electrical energy. They are composed of photovoltaic glass, EVA film, battery cells, EVA film, and backplane laid from top to bottom. The stacked modules need to be evacuated, and then heated to melt the EVA film, so that the photovoltaic glass, battery cells, and backplane are bonded together. After the photovoltaic module is prepared, the appearance of the glass surface needs to be manually inspected. The existing inspection method is to flip the photovoltaic module 90° to expose its glass surface, then use light to illuminate it, and inspect its appearance through naked eye observation by workers.

[0003] An appearance inspection flipping machine is a device that flips over photovoltaic modules and performs appearance inspection. The flipping mechanism of a traditional appearance inspection flipping machine is provided with multiple sets of claws. The claws approach the photovoltaic module from the back, clamp the edge of the photovoltaic module, and then flip the photovoltaic module over. This flipping method has the following disadvantages: (1) The photovoltaic module is large in size. In order to clamp it firmly, the clamping force of the claws is set to be large, which can easily damage the frame of the photovoltaic module; (2) In order to facilitate the lowering of the claws, the photovoltaic module generally needs to be placed on a support frame first so that the edge of the photovoltaic module is suspended in the air, so that the tip of the claw can extend below the edge, which is convenient for clamping. However, the support frame contacts the front of the photovoltaic module and can easily scratch the glass surface.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The utility model aims to address the deficiencies of the prior art and thus provide a photovoltaic module appearance inspection flip device which has a scientific design, will not pinch the frame, is not easy to scratch the glass surface, and is highly practical.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a photovoltaic module appearance inspection flipping device, including a fixed frame, a flip frame and a flip cylinder, the flip frame includes a Japanese-shaped bottom support frame and a hinge seat, the rear frame of the Japanese-shaped bottom support frame is connected to the hinge seat, the rear frame, left frame and right frame of the Japanese-shaped bottom support frame are all provided with photovoltaic panel limit blocks, the hinge seat is hinged on the fixed frame, the two ends of the flip cylinder are respectively hinged to the fixed frame and the hinge seat, and a vertical pressure plate is provided on the fixed frame; the Japanese-shaped bottom support frame is used to lift the photovoltaic panel, and when the flip cylinder drives the Japanese-shaped bottom support frame to flip 90°, the vertical pressure plate presses the photovoltaic panel.

[0007] Based on the above, it further includes an inspection table, and a Chinese character "ri"-shaped storage groove is formed on the inspection table; when the Chinese character "ri"-shaped bottom frame is flipped to the horizontal position, the Chinese character "ri"-shaped bottom frame sinks into the Chinese character "ri"-shaped storage groove, and the photovoltaic panel limiting block protrudes above the Chinese character "ri"-shaped storage groove.

[0008] Based on the above, two convex ribs are further provided on the inspection table, and an inlet plate channel is formed between the two convex ribs. The inlet plate channel gradually narrows from both sides of the input end towards the center of the output end, and the output end of the inlet plate channel is docked with the front end of the Chinese character "ri"-shaped storage groove, so as to control the alignment of the photovoltaic panel with the Chinese character "ri"-shaped bottom frame.

[0009] Based on the above, the vertical pressing plate is installed on the fixed frame through a spring damper, and the vertical pressing plate presses the photovoltaic panel by relying on the resilience of the spring damper.

[0010] Based on the above, an elastic cushion layer is laid on the upper surface of the Chinese character "ri"-shaped bottom frame.

[0011] Based on the above, the middle beam of the Chinese character "ri"-shaped bottom frame extends in the front-rear direction.

[0012] The utility model has substantial features and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0013] (1) The frame of the Chinese character "ri"-shaped bottom frame supports the frame of the photovoltaic panel, and the middle beam supports the middle line position of the photovoltaic panel. The position of the photovoltaic panel is limited by the limiting block. After the Chinese character "ri"-shaped bottom frame is flipped by 90°, the photovoltaic panel is pressed by the vertical pressing plate, and there is no need to clamp the frame, thereby avoiding damage to the frame. Among them, the middle line position of the photovoltaic panel is the dividing position of two battery strings. Therefore, the shielding of the frame and the middle line position does not affect the irradiation inspection of the glass surface by the light.

[0014] (2) When the Chinese character "ri"-shaped bottom frame is placed flat, the Chinese character "ri"-shaped storage groove can accommodate the Chinese character "ri"-shaped bottom frame therein, so that the photovoltaic panel can be placed flat on the inspection table and is not easy to scratch the glass surface.

[0015] (3) The arrangement of the inlet plate channel facilitates guiding the photovoltaic panel to accurately enter the lifting position.

[0016] (4) The spring damper and the elastic cushion layer can be in elastic contact with the photovoltaic panel, playing a role in protecting the photovoltaic panel. At the same time, the spring damper can apply a forward thrust when the photovoltaic panel is flipped, avoiding the photovoltaic panel from flipping backward. Description of the Drawings

[0020] The technical solution of the present utility model will be further described in detail below through specific embodiments.

[0021] As Figure 1 and Figure 2 shown, a flipping device for appearance inspection of photovoltaic modules includes an inspection table 1, a fixed frame 2, a flipping frame and a flipping cylinder 3. The flipping frame includes a day-shaped bottom support frame 4 and a hinge seat 5. The rear frame of the day-shaped bottom support frame 4 is connected to the hinge seat 5. Photovoltaic panel limit blocks 6 are provided on the rear frame, left frame and right frame of the day-shaped bottom support frame 4. The frames of the day-shaped bottom support frame 4 are used to support the frames of the photovoltaic panel. The middle beam of the day-shaped bottom support frame 4 extends in the front-rear direction and is used to support the middle line position of the photovoltaic panel. The photovoltaic panel limit blocks 6 are used to limit the position of the photovoltaic panel.

[0022] The hinge seat 5 is hinged on the fixed frame 2. The two ends of the flipping cylinder 3 are respectively hinged to the fixed frame 2 and the hinge seat 5. A vertical pressing plate 7 is provided on the fixed frame 2. The day-shaped bottom support frame 4 is used to hold the photovoltaic panel. When the flipping cylinder 3 drives the day-shaped bottom support frame 4 to flip 90°, the vertical pressing plate 7 presses the photovoltaic panel tightly.

[0023] A day-shaped storage groove 8 is formed on the inspection table 1. When the day-shaped bottom support frame 4 flips to the horizontal position, the day-shaped bottom support frame 4 sinks into the day-shaped storage groove 8, and the photovoltaic panel limit blocks 6 protrude above the day-shaped storage groove 8. In this way, the photovoltaic panel can be laid flat on the inspection table 1 and is not easy to scratch the glass surface.

[0024] Two convex ribs 9 are also provided on the inspection table 1. An feed-in channel 10 is formed between the two convex ribs 9. The feed-in channel 10 gradually narrows from both sides of the input end towards the center of the output end. The output end of the feed-in channel 10 is docked with the front end of the day-shaped storage groove 8, so as to control the alignment of the photovoltaic panel with the day-shaped bottom support frame 4 and facilitate guiding the photovoltaic panel to accurately enter the lifting position.

[0025] The vertical pressing disc 7 is installed on the fixed frame 2 through a spring damper 11. The vertical pressing disc 7 presses the photovoltaic panel by relying on the resilience of the spring damper 11. An elastic cushion layer is laid on the upper surface of the "day"-shaped bottom frame 4, which is in elastic contact with the photovoltaic panel to protect the photovoltaic panel. At the same time, the spring damper 11 can apply a forward thrust when the photovoltaic panel flips, preventing the photovoltaic panel from flipping backward.

[0026] During specific use, the flipping cylinder 3 first drives the "day"-shaped bottom frame 4 to be laid flat. The photovoltaic panel is pushed in from the input end of the feed channel 10 until it reaches directly above the "day"-shaped bottom frame 4. The frame of the "day"-shaped bottom frame 4 holds the frame of the photovoltaic panel, and the middle beam of the "day"-shaped bottom frame 4 holds the middle line position of the photovoltaic panel. The photovoltaic panel limit block 6 limits the position of the photovoltaic panel; then the flipping cylinder 3 drives the "day"-shaped bottom frame 4 to flip 90°. The vertical pressing disc 7 presses the photovoltaic panel from behind to complete the fixation, and the glass surface is irradiated with light to inspect the appearance of the glass.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still modifications can be made to the specific implementation manners of the present invention or equivalent replacements can be made to some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
