[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown, a photovoltaic irregularly shaped welding strip surface uniform coating device according to an embodiment of the present invention includes a base plate 1, on which a processing mechanism is provided. The processing mechanism includes: a coating component, including a pair of U-shaped frames 2 fixedly attached to the base plate 1, an I-shaped block 3 slidably connected between opposite side walls of the U-shaped frames 2, a rotating rod 4 rotatably connected to the I-shaped block 3 through a first rotating hole, a coating roller 5 connected between the pair of rotating rods 4 through a fixing component, a support plate 6 fixedly attached to the top of the pair of U-shaped frames 2, a pair of electric push rods 7 rotatably connected to the support plate 6 through a pair of first rotating holes, a fixing block 8 rotatably connected to the telescopic end of the electric push rod 7, the fixing block 8 being fixed to the side wall of the I-shaped block 3, and a driving component for driving the pair of rotating rods 4 to rotate on the support plate 6; and a positioning component, which is provided on the base plate 1 for positioning the welding strip.

[0025] The fixing assembly includes a rotating rod 4 with a square block 9 fixed to one end. The square block 9 has a groove 10. The two ends of the coating roller 5 are respectively placed in a pair of grooves 10. The coating roller 5 and the pair of square blocks 9 are detachably connected by bolts 11.

[0026] The drive assembly includes a support plate 6 on top of which a first motor 12 is fixedly connected by a pair of L-shaped rods. The output end of the first motor 12 is provided with a first drive rod 13. The end of the first drive rod 13 away from the first motor 12 is fixedly connected to the base end of one of the pair of electric actuators 7.

[0027] A first bevel gear 14 is fixedly connected to the telescopic end of the electric actuator 7, and a second bevel gear 15 is fixedly connected to the end of the rotating rod 4 away from the square block 9. The first bevel gear 14 and the second bevel gear 15 are meshed and connected.

[0028] During operation, the coating roller 5 is placed at both ends within the grooves 10 of a pair of square blocks 9, and is fixedly connected to the square blocks 9 by bolts 11, enabling the coating roller 5 to be detachably installed. This design facilitates the replacement of coating rollers 5 of different specifications to accommodate photovoltaic irregularly shaped welding strips of different shapes and sizes. By controlling the extension and retraction length of the electric push rod 7, the distance between the coating roller 5 and the welding strip can be precisely adjusted, thereby controlling the coating thickness. The first bevel gear 14 on the extension end of the electric push rod 7 meshes with the second bevel gear 15 on the rotating rod 4, transmitting the power of the first motor 12 to the rotating rod 4, causing the coating roller 5 to rotate. The rotation of the coating roller 5 ensures that the coating material is evenly applied to the surface of the welding strip.

[0029] The positioning component includes a base plate 1 with a pair of sliding slots 16, a sliding block 17 slidably connected in the sliding slots 16, a circular block 18 rotatably connected to the top of the sliding block 17 via a first rotating shaft, and a connecting rod 19 rotatably connected to the bottom of the sliding block 17 via a second rotating shaft.

[0030] An L-shaped plate 20 is fixedly connected to the bottom of the base plate 1. A second motor 21 is fixedly connected to the top of the L-shaped plate 20 laterally. A second drive rod 22 is provided at the output end of the second motor 21. An adjusting rod 23 is fixedly connected to the top of the second drive rod 22. The two ends of the adjusting rod 23 are respectively rotatably connected to the bottom of one end of a pair of connecting rods 19 through a third rotating shaft.

[0031] During operation, by adjusting the position of the circular block 18, the solder strip maintains a stable position and posture during the coating process. The design of the sliding block 17 and the circular block 18 can adapt to photovoltaic irregular solder strips of different shapes and sizes, improving the versatility and flexibility of the device. It can effectively prevent the solder strip from shifting or shaking during the coating process, ensuring the uniformity and consistency of the coating.

[0032] Working principle: The photovoltaic irregularly shaped welding strip to be coated is placed between a pair of circular blocks 18, ensuring that the starting end of the welding strip is correctly positioned. The second motor 21 is started, and the second drive rod 22 at its output end drives the adjusting rod 23 to rotate. The rotation of the adjusting rod 23 pulls a pair of connecting rods 19, and at the same time pulls a pair of sliding blocks 17 to move in the sliding passage 16 groove, so that the pair of sliding blocks 17 move relative to each other. The welding strip is clamped by the pair of circular blocks 18 and transported by the traction equipment in the prior art.

[0033] During coating, the first motor 12 starts, and the first drive rod 13 at its output end drives one of the pair of electric push rods 7 to rotate. The first bevel gear 14 on the telescopic end of the electric push rod 7 meshes with the second bevel gear 15 on the rotating rod 4, transmitting power to the rotating rod 4. This, in turn, drives the coating roller 5 to rotate via the fixing assembly. The rotating rod 4 then drives the coating roller 5 to rotate, and the coating roller 5 uniformly coats the surface of the solder strip with coating material. Guided by the positioning assembly, the solder strip moves smoothly along the coating roller 5. When the coating thickness needs to be adjusted, it can be adjusted by raising and lowering the electric push rod 7.
