[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0019] See also Figure 1 The present invention provides an automatic precision strip filling system for a die-cutting machine. According to design requirements, the system mainly includes a workbench 1, an optical detection system, a strip filling system, a die-cutting pressure test plate 2 and a die-cutting knife plate 3. The workbench 1 is a square table with uniform thickness and flat surface. The table top is made of precision marble to ensure that the working plane is level. A number of holes are evenly opened on the upper surface of the workbench to prevent air from affecting the accuracy.

[0020] The optical detection system includes an optical scanner 4 and a computer host. The optical scanner 4 is fixedly installed at one end of the workbench 1 and connected to the computer host. The computer host is customized with special software for the optical scanner 4. The optical scanner 4 is used to scan and test the indentation depth on the surface of the die-cutting pressure test plate 2. The die-cutting pressure test plate 2 is placed on the workbench 1 below the optical scanner 4. The scanning detection accuracy can reach 0.005mm. The die-cutting pressure test plate 2 is made of non-metallic composite materials, mainly resin asphalt-based composite materials, and has dimensional stability under pressure and shear force. That is, under tension, it is basically inelastic; under pressure, the elongation and shrinkage are extremely low; when the surface is under pressure, it is easy to produce indentations without rebound; the thickness uniformity is high, and the parallelism of the upper and lower surfaces is required to be ±0.005mm.

[0021] The strip repair system includes a strip repair coordinate robot, a strip repair box 5 and a glue coating box 6. The strip repair box 5 and the glue coating box 6 are fixed on the strip repair coordinate robot in sequence and driven by the strip repair coordinate robot to move on a horizontal plane. The strip repair coordinate robot includes a slide rail 7, a first slider 8 and a second slider 9. The slide rail 7 is fixedly installed at the other end of the workbench 1. The upper and lower surfaces of the first slider 8 are provided with grooves perpendicular to each other. The first slider 8 is installed on the slide rail 7 through the slide groove on its lower surface and is slidably connected to the slide rail 7. The second slider 9 is installed on the first slider 8 through the slide groove on the upper surface of the first slider 8 and is slidably connected to the first slider 8. The second slider 9 is set to a long strip shape. The strip repair box 5 and the glue coating box 6 are fixedly installed on the second slider 9 at one end of the side where the workbench 1 is located.

[0022] The die-cutting blade 3 is placed on the workbench 1 below the patching coordinate robot. The computer host is connected to the patching coordinate robot to control the movement of the patching coordinate robot for automatic glue patching. The computer host is also customized with a data management and analysis system to compare the indentation depth on the surface of the test plate scanned by the optical scanner 4, calculate the required patching thickness and push the result to the patching coordinate robot for automatic patching. The patching accuracy of this system is 0.01mm.

[0023] The principles involved in the present invention are:

[0024] Before the die-cutting machine is officially put into production, the die-cutting blade needs to be precisely debugged. First, place the special die-cutting pressure test plate and the die-cutting blade into the corresponding working part of the die-cutting machine and perform the die-cutting operation. Then remove the die-cutting test plate and the die-cutting blade and place them on the corresponding position of the special precision marble work platform. Use the intelligent optical detector to scan the indentation depth on the surface of the test plate, and automatically and intelligently compare it with the standard die-cutting indentation mathematical model pre-stored in the computer system. The microcomputer automatically calculates the error between the indentation on the surface of the test plate and the standard model. Corresponding to the indentation error at different positions, the microcomputer can tell the thickness of the patch that needs to be increased. Then add a patch of corresponding thickness and length to the tail end of the blade at the corresponding position of the upper workbench of the die-cutting machine. Repeat the test of the special die-cutting pressure test plate and the scanning and comparison of the indentation error by the intelligent optical detector. The die-cutting indentation reaches the standard value, and then use the cardboard to operate the die-cutting once as required. If the verification is qualified, stop the debugging and testing. Debugging should be completed within three times.

[0025] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the protection scope of the present invention.
