[0002] With the increasing global demand for renewable energy, solar cell modules, as an important representative of green energy, are gaining a growing market share year by year. However, the uniform application and control of the amount of sealant applied during the manufacturing process of solar cell modules has become a technical challenge. Traditional sealant extrusion devices often require manual adjustment of position and the amount of material discharged, making it difficult to improve production efficiency. Therefore, we propose an automated sealant extrusion device for solar cell modules.

[0003] The prior art discloses a sealant extrusion device for solar cell modules with application number CN202320967995.3, which includes an upper shell, an extrusion assembly, and an adjustment assembly. A lower shell is fixedly installed at the bottom of the upper shell, and an extrusion block is provided inside the lower shell. An adhesive dispensing shell is provided at the bottom of the upper shell. The extrusion assembly is set on the upper shell and the lower shell to make the adhesive dispensing amount more uniform. The adjustment assembly is set on the adhesive dispensing shell to adjust the amount of adhesive dispensing.

[0004] The current technology requires manual rotation and control of the material discharge, which is labor-intensive. The adjustment of the shell position also requires manual adjustment, which is slow and makes it difficult to improve work efficiency.

[0005] Therefore, it is necessary to design a practical and automated sealant extrusion device for solar cell modules. Summary of the Invention

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This utility model provides a technical solution: a sealant extrusion device for solar cell modules, including a worktable 1. A moving mechanism is connected to the inner top of the worktable 1, and a housing 34 is connected to one side of the moving mechanism. An opening and closing mechanism is connected to the bottom of the housing 34. A feeding pipe is fixedly connected to the outside of the housing 34, and a cylinder is fixedly connected to the inner top of the housing 34. A piston rod is connected to the output end of the cylinder, and a circular block is fixedly connected to one side of the piston rod. The circular block fits against the inside of the housing 34. When preparing to start the extrusion work, the solar cell module is placed on the worktable 1. First, sealant is fed into the device through the feeding pipe. Then, the operator controls the moving mechanism to adjust it to the location where sealant is needed. Then, the opening and closing mechanism is controlled, the internal cylinder is activated, the piston rod pushes downward, and the circular block moves downward, pushing the sealant outward until it reaches the designated position. When the sealant inside is almost used up, the circular block moves upward, and sealant is added back into the device through the feeding pipe. The included moving mechanism allows for precise positioning of the housing 34 to the location on the solar cell module where sealant needs to be applied, improving work efficiency and reducing manpower. The included opening and closing mechanism enables automatic material discharge and closure, resulting in a high degree of automation and further enhancing work efficiency.

[0026] The moving mechanism includes a first motor 2, which is fixedly connected to the inner top of the worktable 1. The output end of the first motor 2 is provided with a first rotating shaft 21, and a first O-ring 22 is connected to one side of the first rotating shaft 21. A second motor 3 is fixedly connected to the inner top of the worktable 1, and the output end of the second motor 3 is provided with a second rotating shaft 31. A second O-ring 32 is connected to one side of the second rotating shaft 31. Positioning blocks 33 are provided inside the first O-ring 22 and the second O-ring 32, and the positioning blocks 33 are fixedly connected to the housing 34. A first long block 11 and a second long block 12 are fixedly connected to the inner top of the worktable 1. When the operator... When the first motor 2 is turned on, the first rotating shaft 21 at the output end rotates, and the connected first O-ring 22 moves to the left or right, causing the positioning block 33 to move left or right inside the second O-ring 32. When the operator turns on the second motor 3, the second rotating shaft 31 at the output end rotates, and the connected second O-ring 32 moves forward or backward, causing the positioning block 33 to move back and forth inside the first O-ring 22. This allows for adjustment of the front-back and left-right positions of the housing 34 without requiring the operator to manually move the housing 34. It automatically completes the positioning of the connection points, saving manpower and improving work efficiency.

[0027] Both the outer sides of the first rotating shaft 21 and the second rotating shaft 31 are threaded. The first rotating shaft 21 and the first O-ring 22 are threadedly connected, and the second rotating shaft 31 and the second O-ring 32 are threadedly connected. Because the first rotating shaft 21 and the first O-ring 22 are threadedly connected, the first O-ring 22 should rotate and move when the first rotating shaft 21 rotates. However, the other end of the first O-ring 22 is inside the long groove, which restricts the rotation of the first O-ring 22. Therefore, the first O-ring 22 can only move, thus achieving left and right movement. The threaded connection between the second rotating shaft 31 and the second O-ring 32 follows the same principle, thus achieving forward and backward movement.

[0028] Both the first long block 11 and the second long block 12 have long grooves inside. One end of the first O-shaped block 22 is slidably connected to the inside of the second long block 12. The second O-shaped block 32 is slidably connected to the inside of the first long block 11. The first O-shaped block 22 slides inside the second long block 12. This sliding ensures that the first O-shaped block 22 can move and is located inside the second long block 12, thereby restricting the first O-shaped block 22 to only move, thus realizing the adjustment of the position of the housing 34. The second O-shaped block 32 operates on the same principle.

[0029] The first O-ring 22 and the second O-ring 32 are attached together, and the positioning block 33 passes through the interior of the first O-ring 22 and the second O-ring 32. The top of the positioning block 33 is a round block, and the size of the round block is larger than the hollow part of the first O-ring 22 and the second O-ring 32. The first O-ring 22 and the second O-ring 32 are one above the other, and they are only attached to each other, which facilitates movement. The round block on the top of the positioning block 33 is to prevent the positioning block 33 from falling from the middle.

[0030] The opening and closing mechanism includes a third motor 4, which is fixedly connected to the housing 34. A third rotating shaft is located at the output end of the third motor 4. A first gear 41 is fixedly connected to one side of the third rotating shaft. A ring 43 is fixedly connected to the bottom of the housing 34, and a second gear 42 is rotatably connected to the outer side of the ring 43. The first gear 41 and the second gear 42 are meshed. Five rotating blocks 45 are rotatably connected to one side of the ring 43, and a short rod is fixedly connected to the other side of each rotating block 45. A slanted groove 44 is formed inside the second gear 42, and the short rod corresponds to the slanted groove 44. When the operator opens the third motor 4, the third rotating shaft at the output end... The rotation of the first gear 41 causes the second gear 42 to rotate, while the central ring 43 remains stationary. The second gear 42 rotates clockwise, causing the inclined groove 44 to rotate clockwise as well. The short rod moves along the inclined groove 44 from its inner end to its outer end, causing the rotating block 45 to rotate. The rotating block 45 uses its connection to the ring 43 as a fulcrum; it can rotate but does not move at this fulcrum. Therefore, the rotation at the other end causes the rotating block 45 to open outwards, allowing material to exit the housing 34. By controlling the degree of rotation, the size of the opening can be controlled, thus controlling the amount of material discharged. Controlling the direction of rotation controls the opening and closing of the device. With this opening and closing mechanism, the device can open automatically, eliminating the need for manual opening by operators, and the amount of material discharged can be controlled to adapt to different extrusion requirements.

[0031] The five rotating blocks 45 are combined into a circle; after the combination, no more material is discharged, and the whole thing is sealed.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
