Description

Technical Field

[0001] The utility model relates to a film removing device, in particular to a double-axis moving glass film removing machine. Background Art

[0002] Most of the existing film removing devices in the market are straight-line moving single grinding heads or multiple grinding heads without glass fixing and dust adsorption devices. Each grinding head can only move in a straight line in one direction. To prevent the glass from moving during the grinding process, operators need to hold or press the glass by hand. The disadvantages of the existing film removing devices are obvious, mainly including: ①. When operators hold or press the glass by hand, they need to directly contact the glass, and there is a risk of personal injury if the glass breaks; ②. A large amount of dust is generated during the film removing process, which causes harm to personnel; ③. The grinding head can only move in a straight line in a fixed direction, unable to meet the requirements of different film removing patterns, and has great limitations in use; ④. There is no pressure regulating device, and the pressure of the grinding head on the glass cannot be controlled, which is extremely easy to cause the glass to break. Only glass with a thickness of more than 3 mm can be used for film removing to reduce the glass breakage rate.

[0003] Specifically, the existing single-grinding head film removing device has only one grinding head and no functions of glass adsorption and fixation, dust adsorption and pressure regulation. The grinding head can only move in a straight line along the X-axis or Y-axis direction at a fixed position. At the same time, the high-speed rotating grinding head grinds and removes the film surface on the glass surface. The grinding head can only move in a straight line along the X-axis or Y-axis direction at a fixed position. Therefore, the film removing device cannot directly adjust the grinding width or grinding position by adjusting the position of the grinding head. In addition, the film removing device has no device for vacuum adsorbing and fixing the glass, and can only rely on the friction between the felt on the platform and the glass, and operators hold or press the glass by hand to prevent the glass from moving during production. In the actual production process, due to the large friction during the grinding process of the grinding head, it is impossible to effectively stabilize the glass only by relying on the friction between the felt and the glass and manual pressing. And because the glass is extremely easy to break during the film removing process, the broken glass is extremely easy to cause personal injury. During the film removing process of the grinding head, the film surface or the glass is ground into dust, and a large amount of generated dust is inhaled into the body by the operators or the personnel pressing the glass, causing occupational injuries. There is no pressure regulating device, and the pressure of the grinding head on the glass cannot be controlled during the downward pressing and grinding process of the grinding head. The glass is extremely easy to break during the grinding process. Only glass with a thickness of more than 3 mm can be used for film removing to reduce the glass breakage rate, and it is impossible to improve the problem of glass breakage by unifying the device process parameters.

[0004] Existing multi-grinding head film removal equipment generally has two grinding heads. However, similar to single-grinding head film removal equipment, it lacks functions such as glass adsorption and fixation, dust adsorption, and pressure adjustment. The multi-grinding heads all move linearly along the X-axis and Y-axis directions at fixed positions respectively. While the high-speed rotating grinding heads grind and remove the film on the glass surface, the grinding heads can only move linearly along the X-axis and Y-axis directions at fixed positions. Therefore, this film removal equipment cannot directly adjust the grinding width or position by adjusting the position of the grinding heads. In addition, the film removal equipment does not have a device for vacuum adsorption and fixation of the glass. It can only rely on the friction between the felt on the platform and the glass, and at the same time, the operator holds or presses the glass by hand to prevent the glass from moving during production. In the actual production process, due to the large friction during the grinding process of the grinding heads, relying solely on the friction between the felt and the glass and manual pressing cannot effectively stabilize the glass. And because the glass is extremely easy to break during the film removal process, the broken glass is extremely likely to cause personal injury. During the film removal process of the grinding heads, the film surface or the glass is ground into dust, and a large amount of generated dust is inhaled by the operators or workers, causing occupational harm. Without a pressure adjustment device, the pressure of the grinding heads on the glass during the downward grinding process cannot be controlled, and the glass is extremely easy to break during the grinding process. It can only remove the film from glass with a thickness of more than 3 mm to reduce the glass breakage rate, and it is impossible to improve the problem of glass breakage by unifying the equipment process parameters.

[0021] The following further describes the utility model in conjunction with the drawings and embodiments.

[0022] Figure 1 It is a schematic structural diagram of the biaxial moving glass film removing machine of the utility model.

[0023] Please refer to Figure 1, the double-axis moving glass film removing machine provided by the utility model includes a grinding head 7 and a vacuum adsorption platform 6 for adsorbing glass 5. The grinding head 7 moves along two mutually perpendicular direction axes under the control of a servo motor and rotates at a high speed to remove the film on the glass 5. The vacuum adsorption platform 6 is provided with a dust adsorption device 3 to centrally dispose of the dust generated during the film removal process. A pressure regulating device 2 is arranged on the grinding head 7 to change the pressure of the grinding head 7 on the glass 5.

[0024] For the double-axis moving glass film removing machine provided by the utility model, the grinding head 7 moves along the X-axis 1 under the control of a servo motor to adjust the film removal width of the glass 5, and moves along the Y-axis 4 under the control of a servo motor to adjust the film removal length of the glass 5; the adsorption port on the dust adsorption device 3 is directly opposite to the grinding head 7. Preferably, the servo motor is a stepping motor with a step angle of 0.9 degrees or 1.8 degrees; the adsorption pressure of the vacuum adsorption platform 6 is 0.3 - 1.6 MPa.

[0025] The double-axis moving glass film removing machine provided by the utility model is used as follows: Place the glass 5 to be film-removed on the vacuum adsorption platform 6 by vacuum adsorption. The grinding head 7 rotates at a high speed to remove the film on the glass 5. The dust generated during the film removal process is adsorbed by the dust adsorption device 3 and centrally disposed. By adjusting the pressure regulating device 2, the pressure of the grinding head 7 on the glass 5 is changed. The servo motor controls the position of the grinding head 7 on the X-axis 1 to adjust the film removal width or position on the glass 5. The servo motor controls the position of the grinding head 7 on the Y-axis 4 or forms to adjust the film removal length or position on the glass 5. It is also possible to simultaneously control the position of the grinding head 7 on the X-axis 1 and the Y-axis 4 to adjust the film removal width, position on the glass 5 and form different-shaped film removal pattern effects.

[0026] The utility model redesigns the film removing machine. The grinding head is precisely controlled by a double-axis servo to perform film removal processing on glass film surfaces with different positions, different widths, and different shapes. The bottom of the glass placement plane is provided with functions of negative pressure adsorption and fixation of the glass, dust adsorption function, and pressure adjustment function of the grinding head. It mainly solves the following problems:

[0027] (1) Precise control of the double-axis servo of the grinding head

[0028] The servo motor is adopted to accurately control the positions and strokes of the X-axis and Y-axis, and perform two-axis direction control and position adjustment to meet the requirements of the film removing machine for removing films from glass film surfaces at different positions, with different widths and different shapes. The servo control of the X-axis position changes the requirements for different film removing widths or positions on the glass surface. The film removing width is not limited (for equipment with different size specifications, the film removing width and position are different). Various film removing widths can be achieved by adjusting the servo position of the X-axis and grinding at different positions. The servo control of the Y-axis stroke changes the requirements for different film removing strokes on the glass surface. The film removing stroke is not limited (for equipment with different size specifications, the film removing stroke is different). In addition, different shaped film removing contour effects can be formed by simultaneously adjusting the servo positions of the X-axis and Y-axis.

[0029] (2) Glass vacuum adsorption and fixation function

[0030] The glass film removing machine of the present utility model adds a vacuum adsorption platform 6. The generated vacuum forms a suction force on the glass 5 to fix the glass, preventing the friction force of the grinding head 7 on the glass surface during the film removing process from causing glass displacement, resulting in incorrect film removing positions, glass breakage, etc. At the same time, it solves the problem that traditional film removing machines require personnel to press the glass to prevent glass displacement, liberates personnel, and completely eliminates the need for personnel intervention. It improves the efficiency of the film removing machine and solves the problem of personnel injuries caused by glass breakage during grinding.

[0031] (3) Dust adsorption function

[0032] The glass film removing machine of the present utility model adds a dust adsorption device 3. The adsorption port is located at the grinding head, which is the direct dust generation position. The dust and dust generated during the film removing process of the grinding head are directly sucked away by the adsorption port, improving the equipment environment and reducing the wear of the moving parts of the equipment. Most importantly, it avoids the inhalation of dust by the operating machine or operators, causing occupational injuries.

[0033] (4) Grinding head pressure adjustment function

[0034] The grinding head 7 of the present utility model is configured with a pressure adjustment device 2, and the pressure adjustment device 2 can be a small hydraulic adjustment device. The grinding head of the traditional film removing machine adjusts the position of the grinding head by adjusting the position of the bolt or fixing the position of the grinding head through a cylinder, and can only adjust the position of the grinding head. In the actual production process, there are problems such as glass thickness error, parallelism error between the grinding platform and the grinding head, grinding head diameter error, and grinding head runout. The traditional grinding equipment is extremely likely to cause glass breakage. The film removing machine can only remove films from glass with a thickness of more than 3 mm. For glass with a thickness of less than 3 mm, the film removal cannot guarantee the glass breakage rate. The grinding head pressure adjustment device of this type of film removing machine can adjust the position of the grinding head and preset the pressure on the grinding head. The preset pressure converts problems such as glass thickness error, parallelism error between the grinding platform and the grinding head, grinding head diameter error, and grinding head runout during the film removing process of the grinding head into position compensation and pressure compensation of the grinding head on the glass to improve and solve the glass breakage problem.

[0035] Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the definition of the claims.
