Technical Field
[0001] The utility model relates to the technical field of glass processing equipment, in particular to a precision compensation device for a glass film removal machine. Background Art
[0002] Glass cutting is an important process in the deep processing of glass. When cutting with a glass cutting machine, it is necessary to first do layout, then remove the film, and then cut. Glass cutting machine is a processing machine dedicated to glass processing and unloading. Glass cutting machine generally includes an air-floating feeding table arranged end to end, a double-bridge overpass cutting table, and a control system. A cutting knife is installed on the double-bridge overpass cutting table. The transmission structure on the double-bridge overpass cutting table drives the cutting knife to move on the horizontal plane, thereby cutting the glass placed on the surface of the double-bridge overpass cutting table. Before cutting the glass, a grinder is needed to grind and remove the film on the surface of the glass.
[0003] In the prior art, when a grinder is used to grind and remove film from the glass surface, the outer peripheral surface of the grinding wheel will be worn after working for a long time, and the radius of the grinding wheel will be reduced. If the grinding wheel is still used to grind and remove film from the glass surface according to the original descending height, the grinding depth will be insufficient and the film removal standard will not be met.
[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art. Utility Model Content
[0005] The purpose of the utility model is to design a device that can automatically detect the wear radius of the grinding wheel after a predetermined number of grinding times.

A precision compensation device for a glass film removal machine is provided to solve the above-mentioned deficiencies in the technology.
[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precision compensation device for a glass film removal machine, comprising a double-bridge overpass cutting table, a gantry double direct-drive structure installed on the double-bridge overpass cutting table, a machine head installed on the gantry double direct-drive structure, and a grinder installed on the machine head, the grinder consisting of a shell, a first servo motor installed on one side of the shell, and a grinding wheel fixedly installed at the output end of the first servo motor, a vertical moving component for controlling the vertical movement of the grinder up and down is installed between the grinder and the machine head, and a servo motor is installed on one side of the grinder and the machine head respectively.

[0015] Preferably, the width of the through hole is 1.5-2 times the thickness of the grinding wheel, and the length of the through hole is 0.5-0.8 times the diameter of the grinding wheel;
[0016] The size of the grinding wheel is limited so that the grinding wheel can pass through the through hole to press the pressure-bearing member.

[0030] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0032] Example:
[0033] like Figure 1-4 As shown, it includes a double-bridge overpass cutting table 1, a gantry double direct drive structure 2 installed on the double-bridge overpass cutting table 1, a machine head 3 installed on the gantry double direct drive structure 2, and a grinder 4 installed on the machine head 3. The grinder 4 consists of a housing 401, a first servo motor 402 installed on one side of the housing 401, and a grinding wheel 403 fixedly installed at the output end of the first servo motor 402. An assembly table 501 is installed on the machine head 3. A vertical guide rail 502 is fixedly connected to the side wall of the assembly table 501. A vertical slider 503 is slidably installed on the vertical guide rail 502. A connecting piece 504 is installed on one side of the vertical slider 503. A screw 505 is spirally driven in the vertical slider 503. A second servo motor 506 is fixedly installed on the top of the assembly table 501. The output end of the second servo motor 506 is connected to the end of the screw 505. Fixed connection, the grinder 4 is installed at the bottom of the connecting member 504, the first transmitter 601 and the first receiver 602 of the first position sensor 6 are respectively installed on the assembly table 501 and the connecting member 504, a positioning member 8 is arranged in the double-bridge overpass cutting table 1, a hollow member 701 is fixedly installed on the positioning member 8, a sliding column 702 passes through and slidably connected to the top of the hollow member 701, a pressure-bearing member 703 is fixedly installed on the top of the sliding column 702, a spring 704 is installed between the pressure-bearing member 703 and the hollow member 701, a through hole 705 passes through the side wall of the hollow member 701, a second transmitter 901 and a second receiver 902 of the second position sensor 9 are respectively installed on the positioning member 8 and the bottom of the sliding column 702, and a through hole 14 is also opened at the top of the double-bridge overpass cutting table 1 perpendicular to the pressure-bearing member 703.
[0034] The specific implementation method is as follows: when the number of times the film is removed from the glass surface reaches a set value, the gantry dual direct drive structure 2 controls the grinding wheel 403 on the grinder 4 to move to just above the pressure-bearing member 703, and then the output shaft of the second servo motor 506 rotates to drive the grinder 4 to descend. When the grinder 4 descends, the first transmitter 601 and the first receiver 602 in the first position sensor 6 are offset from each other and do not receive signals. At this time, the control program in the prior art starts to measure the moving distance of the grinder 4 according to the number of rotations of the second servo motor 506.
[0035] When the grinding wheel 403 in the grinding machine 4 contacts the pressure-bearing member 703 and continues to descend, the pressure-bearing member 703 drives the slide column 702 to descend while compressing the spring 704. When the second receiver 902 installed on the slide column 702 descends to receive the signal of the second transmitter 901, the second servo motor 506 stops rotating, and the descending distance D of the grinding wheel 403 is obtained.
[0036] Then compare the distance D of this descent with the distance C of the last descent. The difference between C and D is the wear length of the radius of the grinding wheel 403 after the glass surface is recently polished. When the glass surface is polished next, a wear length distance needs to be superimposed on the original descent distance of the grinder 4 to ensure that the grinding depth of the grinding wheel 403 on the glass surface is within the required range.
[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. 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.
[0038] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
