[0034] Please see Figure 1-4 This embodiment provides a filter screen wrapping and welding device for bending and welding the strip-shaped filter screen 100 into a ring shape. The filter screen wrapping and welding device includes:

[0035] The lifting mechanism 1 includes a lifting motor 11 and a lifting platform 12. The lifting platform 12 is installed at the output end of the lifting motor 11. The lifting motor 11 is used to drive the lifting platform 12 to move in the vertical direction. The top surface of the lifting platform 12 is used to place the filter screen 100, and a pressure groove 13 is provided on the top surface of the lifting platform 12.

[0036] Positioning mechanism 2, the positioning mechanism 2 includes a positioning rotary motor 21 and a positioning column 22, the positioning column 22 is installed at the output end of the positioning rotary motor 21, the positioning rotary motor 21 is used to drive the positioning column 22 to rotate and press down in the direction of the pressing groove 13, the width of the pressing groove 13 is not less than the positioning column 22;

[0037] The bending mechanism 3 includes a bending motor 31 and a bending arm 32. The bending arm 31 is installed at the output end of the bending motor 31. The bending motor 31 is used to drive the bending arm 32 to move in the horizontal direction. The height of the end of the bending arm 32 is flush with the top height of the positioning post 22 pressed down to the lowest point. The end of the bending arm 32 is provided with a hollow groove 321.

[0038] Welding machine 4 is disposed above bending mechanism 3, with its output end facing the placement area of ​​filter screen 100. Welding machine 4 is used to output laser light passing through the hollow groove 321 and to perform laser welding on filter screen 100 after bending arm 32 pushes it horizontally and bends filter screen 100.

[0039] Based on the above structure, during operation, the operator first places the pre-set, unbent object, such as... Figure 3 The filter screen 100 is placed in a designated area on the lifting platform 12. Then, the positioning rotary motor 21 in the positioning mechanism 2 is started, and the positioning column 22 rotates 90 degrees and presses down, so that its position is aligned with the pressing groove 13. Then, the lifting motor 11 in the lifting mechanism 1 runs, which lifts the lifting platform 12 and drives the filter screen 100 to rise, causing relative movement with the positioning column 22. This causes the positioning column 22 to gradually enter the pressing groove 13, and the strip-shaped filter screen 100 on the lifting platform 12 is bent by the bottom of the positioning column 22 until the positioning column 22 bends the filter screen 100 into an almost U-shape. Then, the bending motor 31 of the bending mechanism 3 runs. In this application, two sets of bending mechanisms 3 can be provided. The two sets of bending mechanisms 3 are mirror images arranged on both sides of the downward pressing direction of the positioning column 22, so that the U-shaped filter screen 100 moves from both sides toward the center until it is completely bent and attached to the positioning column 22, so that it is completely attached to the outer surface of the positioning column 22. Finally, the welding machine 4 is started and performs laser welding on the bent filter screen 100, so that the laser passes through the hollow groove 321 of the bending arm 32 and is projected onto the top surface of the filter screen 100, welding it at high temperature. Thus, the welding of the filter screen 100 is completed. There can be four welding points.

[0040] The output ends of the lifting motor 11, the positioning rotary motor 21, and the bending motor 31 mentioned above can be configured as motor shaft assemblies for transmission, driving the corresponding downstream components to reciprocate through stroke motion, such as the output ends of the lifting motor 11 and the positioning rotary motor 21, or driving the corresponding components to rotate through gears or other components at the end of the motor shaft, such as the output end of the bending motor 31.

[0041] In the above solution, the filter screen 100 can be quickly bent using the positioning column 22 as a base, with the help of the lifting mechanism 1 and the bending mechanism 3, and then welded into shape using the welding machine 4, resulting in high processing efficiency. Specifically, the filter screen 100 can be first squeezed and bent using the lifting platform 12, and then bent to fit the positioning column 22 using the bending arm 32. After these two steps are completed quickly, the filter screen 100 can be directly laser welded from the top through the hollow groove 321 using the welding machine 4, integrating bending and welding into one process, which is compact and highly efficient.

[0042] In another embodiment, the positioning post 22 is provided with an annular groove 23, the width of which is the same as the width of the filter screen 100. The annular groove 23 is used to accommodate the deformed filter screen 100 after the positioning post 22 is pressed down and the lifting platform 12 is raised. The annular groove 23 can be set as a thick groove formed by a recess on the surface of the positioning post 22, the thickness of which is at least not less than that of the filter screen 100, and the width of which is not less than that of the bending arm 32, so that the bending arm 32 can be completely embedded in the hollow groove 321, which helps with bending and pressing before complete forming.

[0043] The positioning mechanism 2 further includes a positioning cylinder 24 and a positioning block 25. The positioning block 25 is installed at the output end of the positioning cylinder 24 and is located on one side of the positioning post 22 in the downward pressing direction. The positioning cylinder 24 drives the positioning block 25 to move vertically, so that the pressed positioning post 22 is clamped by the positioning block 25. The end of the positioning block 25 and the positioning post 22 can be configured as a conforming structure that fits into each other, making the positioning post 22 clamped by the positioning block 25 less prone to shaking and more stable during bending.

[0044] In another embodiment, a limiting block 14 is provided on the top surface of the lifting platform 12, and the filter screen 100 is placed on one side of the limiting block 14. The limiting block 14 is used to prevent the filter screen 100 from shifting in the horizontal direction. Multiple limiting blocks 14 are provided at intervals on the top surface of the lifting platform 12. Specifically, four limiting blocks 14 can be provided, respectively located at the four corners of the strip-shaped filter screen 100, to achieve a better fixing and limiting effect.

[0045] Furthermore, the bending mechanism 3 also includes a bending cylinder 33 and a pressure plate 34. The pressure plate 34 is installed at the output end of the bending cylinder 33 and is located at the top of the bending arm 32. The bending cylinder 33 drives the pressure plate 34 to move vertically, so that the bending arm 32 is pressed vertically onto the bent filter screen 100. Specifically, after the bending arm 32 moves horizontally and bends, the pressure plate 34 then immediately presses vertically down onto the bending arm 32, so that the bending arm 32 presses the filter screen 100 tightly, resulting in a better forming effect and preventing warping.
