[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1 to 6 , the present invention provides a technical solution:

[0029] A laser slitting and tinning production line for copper foil processing includes a slitting frame 1, the slitting frame 1 includes an unwinding roller 2 for placing a copper foil strip 15 and a winding roller 4 for winding the slitting copper foil strip 15, a laser slitting machine 8 for slitting and a tin furnace 6 for tinning are arranged between the slitting roller 2 and the winding roller 4, the laser slitting machine 8 is provided with multiple groups of laser tubes 9 facing the copper foil strip 15, the lower end of the tin furnace 6 is provided with a lifting device 14, the lifting device 14 is installed on the slitting frame 1, a flux box 11 and a felt wiping box 12 are provided between the tin furnace 6 and the laser slitting machine 8, a guide device 13 for cooling the tinned copper foil strip 15 is provided between the tin furnace 6 and the winding roller 4, and a control panel 5 electrically connected to the tin furnace 6, the laser slitting machine 8 and the guide device 13 is provided on the slitting frame 1.

[0030] The continuous movement of the copper foil strip 15 is achieved by setting an unwinding roller 2 and a winding roller 4, and slitting is achieved by using multiple groups of laser tubes 9. The slit copper foil strip 15 is cleaned and pre-treated by using a flux box 11 and a felt wiping box 12, thereby improving the quality of the tin coating process. The excess copper foil after slitting is recycled using a recycling roller 3.

[0031] The distances between multiple groups of laser tubes 9 are adjustable and installed on the laser slitting machine 8. A laser head 17 is provided on the laser tube 9. A calibration component is provided at the front end of the laser slitting machine 8. The calibration component includes a top roller 19 fixed on the slitting frame 1. A double ring 21 for threaded propulsion adjustment is provided on one side of the top roller 19. A guide rail 34 located at the upper end of the top roller 19 is provided on the double ring 21. A scale rod 32 is provided on one side of the guide rail 34. A positioning block 31 slidingly installed along the direction of the scale rod 32 is provided on the guide rail 34. A magnifying glass 26 is provided at the lower end of the positioning block 31. A plane mirror 37 located above the magnifying glass 26 is provided at the upper end of the positioning block 31. An optical groove 36 is provided on the side of the plane mirror 37 facing the laser slitting machine 8. The laser head 17 and the optical groove 36 are arranged at the same height.

[0032] The sliding position of the positioning block 31 is limited by the guide rail 34, and the double ring 21 is pushed forward and the magnifying glass 26 is used to cooperate to achieve accurate origin calibration. The sliding of the positioning block 31 is used to accurately pre-position the slitting width, thereby adjusting the position of the laser tube 9 so that the laser head 17 thereon can pass through the position of the optical groove 36, thereby achieving accurate and convenient position adjustment.

[0033] Working principle: First, install the uncut copper foil strip 15 on the unwinding roller 2, and adjust the position before cutting. Use the threaded pushing and squeezing to drive the double ring 21 to slide along the top roller 19, so that the scale rod 32 is adjusted to be directly above the top roller 19, and then adjust the position of the optical groove 36 of the positioning block 31 to the origin position facing the scale rod 32. As the double ring 21 is pushed forward, the positioning block 31 moves toward one side of the copper foil strip 15, and the side of the copper foil strip 15 is magnified by the magnifying glass 26. When the side of the copper foil strip 15 is reflected in the optical groove 36, the origin correction is completed and the position of the scale rod 32 is fixed.

[0034] Then, according to the cutting size, adjust the position of the positioning block 31 and the corresponding position on the scale rod 32. After positioning, adjust the position of the laser tube 9 so that the laser of the laser head 17 on the laser tube 9 can accurately enter the optical groove 36. The adjustment is completed, thus achieving precise position adjustment of multiple groups of laser tubes 9.

[0035] Example 2: On the basis of Example 1, an adjusting frame 10 is provided on the slitting frame 1, and the calibration component is installed in the adjusting frame 10. A lower pressure roller 7 is provided between the calibration component and the unwinding roller 2. The lower pressure roller 7 is located at the lower end of the top roller 19. The copper foil strip 15 on the unwinding roller 2 extends smoothly along the lower end of the lower pressure roller 7 to the upper end of the top roller 19, and extends parallel to the lower end of the laser tube 9. A recovery roller 3 for recovering the side rough material after slitting is provided between the calibration component and the flux box 11.

[0036] The extension direction of the copper foil strip 15 is limited by the lower pressing roller 7, so that the copper foil strip 15 is pressed and extended on the upper end of the top roller 19, which is convenient for subsequent calibration.

[0037] The lower end of the laser tube 9 faces the copper foil tape 15, and the laser head 17 faces the copper foil tape 15 through the lower end of the laser tube 9. The laser head 17 is installed on the outer wall of the laser tube 9 through the mounting block 16. The upper end of the laser tube 9 is telescopically installed on the laser slitting machine 8, and the laser tube 9 is electrically connected to the laser slitting machine 8.

[0038] The installation block 16 facilitates the installation and height adjustment of the laser head 17 on the laser tube 9 .

[0039] A fixed side plate 18 is provided on one side of the top roller 19, and the fixed side plate 18 is fixed on the slitting frame 1. The double ring 21 includes two groups of rings connected by a slide rod 29. A side groove 24 that cooperates with the slide rod 29 for sliding insertion is provided on the outer wall of the top roller 19. A screw 23 is provided at the end of the top roller 19. A drive assembly for extruding the double ring 21 is provided on the screw 23. The drive assembly includes a screw ring 25 and a pressure ring 27. A pressure groove 30 that rotates with the pressure ring 27 is provided on the ring on the side of the double ring 21 close to the screw 23. The outer side of the pressure ring 27 is defined by a cover ring 40. The pressure ring 27 is connected to the screw ring 25 through a connecting rod 28, and the screw ring 25 is threaded and rotatably sleeved on the screw 23.

[0040] The purpose of advancing the double ring 21 is achieved by utilizing the threaded rotation of the screw ring 25 on the screw rod 23. The position of the double ring 21 is limited by utilizing the cooperation of the side groove 24 and the slide rod 29 to avoid the deviation of the scale rod 32 caused by the rotation of the double ring 21. As a result, under the threaded advancement, the double ring 21 can only slide along the top roller 19 and cannot rotate.

[0041] Example 3: On the basis of Example 2, a slide groove is provided on the guide rail 34, and a slider 33 slidably inserted in the slide groove is provided at the lower end of the positioning block 31. The upper end of the positioning block 31 extends to the top of the guide rail 34, and a plane mirror 37 and a magnifying glass 26 stacked up and down are provided in the positioning block 31. One end of the light groove 36 faces the scale rod 32, and the other end port of the light groove 36 is set as a conical inclined mouth, and the inner diameter of the conical inclined mouth is larger than the width of the light groove 36.

[0042] Light guiding is achieved by providing a tapered inclined opening, but the tapered inclined opening will cause scattering of the laser light, making it difficult to accurately judge whether the laser light has completely entered the optical groove 36 .

[0043] Magnetic strips 20 are provided on both sides of the upper end port of the slide groove, the middle step surface of the positioning block 31 is pressed on the magnetic strip 20, and a groove 39 is provided on the middle step surface facing the magnetic strip 20, the groove 39 is connected to the inner cavity of the positioning block 31, and a magnetic block 38 is rotatably installed in the inner cavity of the positioning block 31. A turntable 35 is provided on the upper end of the magnetic block 38, and the guide rail 34 is fixedly installed on the ring of the double ring 21 close to the copper foil tape 15 through the fixing part 22, and the other end of the guide rail 34 slides and fits the upper end surface of the fixed side plate 18.

[0044] By arranging the cooperation between the magnetic strip 20 and the magnetic block 38, the purpose of adsorbing and fixing the positioning block 31 is achieved. By arranging the turntable 35 to control the position of the magnetic block 38, the circular angle of the magnetic block 38 and the position of the groove 39 is switched. When the positioning block 31 needs to be fixed, the turntable 35 is installed so that the magnetic block 38 is opposite to the groove 39, and adsorption with the magnetic strip 20 is achieved, thereby achieving the purpose of fixing the position of the positioning block 31. When the position of the positioning block 31 needs to be adjusted, the turntable 35 is rotated to achieve dislocation, thereby releasing the magnetic fixation, and facilitating the position adjustment of the positioning block 31 on the guide rail 34.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
