DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The present invention provides Figure 1-6 A substrate stripping tool for copper-clad substrate production shown in the figure comprises a workbench 1 and a substrate 2. A square opening is provided on the workbench 1, and a conveying mechanism is installed in the square opening. The substrate 2 can move following the conveying mechanism. A first U-shaped plate 3 and a second U-shaped plate 4 are fixedly provided on the workbench 1. The first U-shaped plate 3 and the second U-shaped plate 4 are both arranged across the square opening, and the first U-shaped plate 3 is located on the left side of the second U-shaped plate 4. A downward pressure limiting mechanism that can be adjusted up and down is installed in the first U-shaped plate 3. A longitudinally arranged separation knife 5 is provided in the second U-shaped plate 4, and the blade of the separation knife 5 faces the first U-shaped plate 3. Moving blocks 6 are fixedly provided on both sides of the separation knife 5. Vertically arranged strip openings are provided on both sides of the second U-shaped plate 4. Two moving blocks 6 are respectively vertically slidably arranged in the two strip openings. A group of elastic mechanisms that apply upward elastic force to the moving blocks 6 are provided in the two strip openings.

[0027] like Figure 1-Figure 3 As shown, the conveying mechanism includes a servo motor 7, a conveyor belt 8 and two conveyor rollers 9. The two conveyor rollers 9 are longitudinally arranged in the opening and symmetrically distributed on the left and right. A rotating rod is fixedly inserted into the end face of each conveyor roller 9. The front and rear ends of each rotating rod are rotatably connected to the front and rear sides of the opening through a first bearing. The servo motor 7 is fixedly arranged on the front side of the workbench 1. The front end of one of the rotating rods extends to the front side of the workbench 1 and is fixedly connected to the output end of the servo motor 7. A plurality of evenly distributed push plates 10 are fixedly arranged on the outer surface of the conveyor belt 8. The servo motor 7 can drive one of the conveyor rollers 9 to rotate, and the cooperation of the two conveyor rollers 9 drives the conveyor belt 8 to circulate. The conveyor belt 8 drives the plurality of push plates 10 to move, thereby pushing the substrate 2 on the conveyor belt 8 to move.

[0028] like Figure 1-Figure 5It is shown that each group of elastic mechanisms includes a guide rod 11 and a tension spring 12. The guide rod 11 is vertically fixed in the strip-shaped opening. A guide hole is opened at the upper end of the moving block 6 and is slidably mounted on the guide rod 11. The tension spring 12 is mounted on the guide rod 11 and is located above the moving block 6. The upper and lower ends of the tension spring 12 are respectively fixedly connected to the second U-shaped plate 4 and the moving block 6, so that the separation knife 5 can continuously apply an upward pulling force to the separation knife 5, so that the separation knife 5 is in close contact with the lower side of the ceramic sheet when separating the copper sheet and the ceramic sheet below, and can pull the separation knife 5 upward to reset after separation.

[0029] At the same time, a pressing rod 13 is fixedly provided at the front end of the front moving block 6, so that people can press the separation knife 5 downwards.

[0030] like Figure 3 and Figure 6 As shown, the downward pressure limiting mechanism includes a U-shaped frame 14, two pressure rollers 15, a guide assembly and a height adjustment assembly. The U-shaped frame 14 is vertically slidably arranged in the first U-shaped plate 3 through the guide assembly and can be height-adjusted through the height adjustment mechanism. The two pressure rollers 15 are longitudinally arranged in the U-shaped frame 14, and each pressure roller 15 is rotatably connected to the front and rear sides of the U-shaped frame 14 through a rotating shaft.

[0031] At the same time, the height adjustment component includes a threaded sleeve 16, a threaded rod 17 and a rotating wheel 18. The threaded sleeve 16 is vertically fixed in the middle of the upper end of the U-shaped frame 14, and the threaded rod 17 is inserted in the threaded sleeve 16 and threadedly connected with the threaded sleeve 16. The upper end of the threaded rod 17 is rotatably connected to the upper side wall of the first U-shaped plate 3 through a second bearing, and the upper end of the threaded rod 17 is fixedly connected to the rotating wheel 18, which is convenient for adjusting the height of the two pressure rollers 15 so that the two pressure rollers 15 are in contact with the upper side of the substrate 2, thereby preventing the substrate 2 from being lifted up when the separation knife 5 peels off the substrate 2.

[0032] In addition, the guide assembly includes two guide sliders 19, which are respectively fixed on the front and rear sides of the U-shaped frame 14. The opposite sides of the first U-shaped plate 3 are provided with guide grooves for the guide sliders 19 to slide vertically, which can guide the vertical movement of the U-shaped frame 14 and make the vertical movement of the U-shaped frame 14 more stable.

[0033] like Figure 1-Figure 3 As shown, two symmetrically distributed handle bars 20 are fixedly provided on the circumferential side wall of the rotating wheel 18, so that people can turn the handle bars 20 to drive the rotating wheel 18 to rotate.

[0034] Working principle of the present invention: When the present invention is in use, the peeled substrate 2 is placed on the conveyor belt 8, and then conveyed by the conveyor belt 8. When the substrate 2 moves to the first U-shaped plate 3, the rotating wheel 18 drives the threaded rod 17 to rotate, and the rotation of the threaded rod 17 drives the threaded sleeve 16 to move downward, and the threaded sleeve 16 drives the U-shaped frame 14 to move downward, and the U-shaped frame 14 drives two pressure rollers 15 to move downward, so that the two pressure rollers 15 are in contact with the upper side of the substrate 2, and then the pressing rod 13 is pulled downward to drive one of the moving blocks 6 to move downward, thereby driving the separation knife 5 to move downward until it moves to the bottom of the ceramic sheet in the middle of the substrate 2, and the substrate 2 is continued to be driven to move by the conveyor belt 8. When the substrate 2 moves to the second U-shaped plate 4, the separation knife 5 is inserted under the ceramic sheet, and the pressing rod 13 is released. Under the action of the two tension springs 12, the separation knife 5 will be in close contact with the lower side of the ceramic sheet. As the conveyor belt 8 drives the substrate 2 to continue to move, the separation knife 5 will cut and separate the lower copper sheet and the ceramic sheet until the ceramic sheet is separated from the lower copper sheet. Then, under the action of the two tension springs 12, the separation knife 5 is pulled upward to reset, and the conveyor belt 8 drives the peeled substrate 2 to continue to move. Through the upper device, the ceramic sheet on the substrate 2 can be automatically peeled and separated without manual separation, which not only reduces people's labor intensity but also improves processing efficiency.

[0035] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
