Description

Technical Field

[0001] The invention relates to the technical field of film removal equipment, in particular to a horizontal multi-station film removal equipment. Background Art

[0002] Coated glass is glass that has one or more layers of metal, alloy or metal compound thin films coated on its surface to change the optical properties of the glass to meet certain specific requirements. During the reprocessing of the coated glass in the later stage, it is necessary to remove the film pattern of a specific shape at a certain position of the coated glass. This process requires the use of film removal equipment. The film removal process of existing film removal equipment includes four steps: feeding, correction, film removal, and discharging. The four steps are performed in sequence, resulting in a long overall time consumption and low film removal efficiency. In addition, during the film removal process, the coated glass is supported by a conveyor line, and the accuracy in the height direction is difficult to guarantee. When the laser is focused on the conveyor line, it is easy to cause damage to the conveyor line. Summary of the invention

The laser film removal mechanism comprises a horizontal moving module and a laser film removal device arranged on the horizontal moving module. The horizontal moving module drives the laser film removal device to reciprocate between the stations.

[0006] As a preferred embodiment, the correction mechanism includes a plurality of first correction components arranged in a first direction and a plurality of second correction components arranged in a second direction, wherein the first direction intersects with the second direction; a plurality of the first correction components are arranged on two opposite sides of the film removal station, and the first correction components are used to correct the workpiece in the first direction; a plurality of the second correction components are arranged on the other opposite sides of the film removal station, and the second correction components are used to correct the workpiece in the second direction.

[0007] As a preferred embodiment, several of the second correction components are divided into at least one middle correction component and at least two end correction components, the end correction components are respectively arranged at the two ends of the two film removal stations, and the middle correction component is arranged between the two film removal stations, the middle correction component, the end correction component and the first correction component all include a correction moving module and a limit part arranged on the correction moving module, wherein, in the middle correction component, the correction moving module drives the limit part to move back and forth between the two film removal stations.

[0008] As a preferred solution, the top surface height of the limit member exceeds the top surface height of the support assembly; when the conveyor line lifting assembly drives the feeding conveyor line to rise to the highest position, the top surface height of the limit member is lower than the top surface height of the feeding conveyor line.

[0009] As a preferred solution, the support assembly includes a support plate, an adjustment rod arranged on the support plate, and an inner stud arranged on the upper end of the adjustment rod, and the height of the upper end of the adjustment rod extending out of the support plate is adjustable.

[0010] As a preferred solution, the top surface of the inner stud is a spherical surface.

[0011] As a preferred embodiment, the feeding mechanism further comprises a lifting frame, and a plurality of the feeding conveyor lines are arranged on the lifting frame in parallel and at intervals, and the lifting frame is arranged on a conveyor line lifting component, and the conveyor line lifting component drives the lifting frame and the feeding conveyor line to rise and fall.

[0015] The beneficial effect of the horizontal multi-station film removal equipment disclosed in the present invention is that when the laser film removal device performs film removal processing on a glass workpiece located at a film removal station of a feeding mechanism, another glass workpiece is transported to the feeding conveyor line of another feeding mechanism, and the feeding conveyor line transports it to the film removal station. The conveyor line lifting component drives the corresponding feeding conveyor line to descend, so that the feeding conveyor line descends below the top surface of the support component, so that the glass workpiece is supported by the support component. The correction mechanism corrects and positions the workpiece. When the film removal of the glass workpiece located at the film removal station of a feeding mechanism is completed, the horizontal moving module moves the laser film removal device to the top of the film removal station of another feeding mechanism to remove the film from the other glass workpiece. The conveyor line lifting component corresponding to the glass workpiece that has been film removed drives the corresponding feeding conveyor line to rise, so that the glass workpiece feeding conveyor line supports it, and then the feeding conveyor line moves it out. Since one glass workpiece is undergoing film removal processing, the other glass workpiece can be discharged, fed, and corrected synchronously, thereby greatly improving the film removal efficiency. At the same time, when the equipment is removing the film by laser, the glass workpiece is supported by the support assembly, which makes it easier to ensure the positioning height. At this time, the feeding conveyor line is far away from the focus of the laser, avoiding damage to the feeding conveyor line. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0024] Please refer to Figure 1A horizontal multi-station film removal device includes a frame 10, a feeding mechanism 20, a correction mechanism 30 and a laser film removal mechanism 40.

[0025] Please refer to Figure 3 and Figure 4 The feeding mechanism 20 is arranged on the frame 10 and is divided into at least two groups. Each group of the feeding mechanism 20 includes a feeding conveyor line 21, a conveyor line lifting assembly 22 and a support assembly 23. The feeding conveyor line 21 is arranged on the conveyor line lifting assembly 22. A film removal station is arranged on the conveying path of the feeding conveyor line 21. The support assembly 23 is arranged at the film removal station. The conveyor line lifting assembly 22 drives the feeding conveyor line 21 to descend below the top surface of the support assembly 23. Among them, when the feeding conveyor line 21 conveys the glass workpiece 50, the top surface of the feeding conveyor line 21 is higher than the top surface of the support assembly 23. When the workpiece 50 is transported to the film removal station, the conveyor line lifting assembly 22 drives the feeding conveyor line 21 to descend below the top surface of the support assembly 23. In this embodiment, the feeding mechanism 20 is provided with two groups, and each group of the feeding mechanism 20 corresponds to a film removal station.

[0026] Please refer to Figure 1 and Figure 2 , the correction mechanism 30 is arranged at the film removal station, and the correction mechanism 30 is used to correct and position the workpiece 50. The laser film removal mechanism 40 is arranged above the feeding mechanism 20, and the laser film removal mechanism 40 includes a horizontal moving module 41 and a laser film removal device 42 arranged on the horizontal moving module 41, and the horizontal moving module 41 drives the laser film removal device 42 to reciprocate between the stations. In this embodiment, the laser film removal device 42 is provided with one group. In another embodiment, the laser film removal device 42 can be provided with multiple groups to further improve the film removal efficiency.

[0027] Implementation process: When the laser film removal device 42 performs film removal processing on the glass workpiece 50 located at the film removal station of a feeding mechanism 20, another glass workpiece 50 is transported to the feeding conveyor line 21 of another feeding mechanism 20, and is transported to the film removal station by the feeding conveyor line 21. The conveyor line lifting component 22 drives the corresponding feeding conveyor line 21 to descend, so that the feeding conveyor line 21 descends below the top surface of the support component 23, so that the glass workpiece 50 is supported by the support component 23. The correction mechanism 30 corrects and positions the workpiece 50. When the film removal of the glass workpiece 50 located at the film removal station of a feeding mechanism 20 is completed, the horizontal moving module 41 moves the laser film removal device 42 to the top of the film removal station of another feeding mechanism 20, and removes the film of the other glass workpiece 50. The conveyor line lifting component 22 corresponding to the glass workpiece 50 that has been film removed drives the corresponding feeding conveyor line 21 to rise, so that the glass workpiece 50 is supported by the feeding conveyor line 21, and then the feeding conveyor line 21 moves it out.

[0028] Please refer to Figure 6 The support assembly 23 of the feeding mechanism 20 includes a support plate 231, an adjustment rod 232 disposed on the support plate 231, and an inner stud 233 disposed on the upper end of the adjustment rod 232. The height of the upper end of the adjustment rod 232 extending out of the support plate 231 is adjustable. The top surface of the inner stud 233 is a spherical surface, and the vertex of the spherical surface is the support point. At this time, the top surface of the inner stud 233 is in point contact with the workpiece 50, thereby minimizing the contact area between the inner stud 233 and the workpiece 50. When the laser focus is focused on the top surface of the inner stud 233, the contamination of the glass is avoided to the greatest extent.

[0029] The adjusting rod 232 includes an adjusting screw and two nuts passing through the adjusting screw, the two nuts are threadedly connected to the adjusting screw, and the two nuts clamp the support plate 231 during installation. The inner stud 233 is specifically a nylon inner stud 233. By adjusting the height of the top surface of the inner stud 233, the problem of difficulty in calibrating large-format glass is solved. The point support adopts horizontal calibration that can be adjusted up and down, and the height difference accuracy of each point can be adjusted to within 5 threads.

[0030] Please refer to Figure 4 The feeding mechanism 20 further includes a lifting frame 24, and a plurality of the feeding conveyor lines 21 are arranged in parallel and at intervals on the lifting frame 24. The lifting frame 24 is arranged on the conveyor line lifting assembly 22, and the conveyor line lifting assembly 22 drives the lifting frame 24 and the feeding conveyor line 21 to rise and fall, so that the lifting heights of the plurality of feeding conveyor lines 21 of each group of the feeding mechanism 20 are the same.

[0031] Please refer to Figure 3 The correction mechanism 30 includes a plurality of first correction components 31 arranged in a first direction and a plurality of second correction components 32 arranged in a second direction, wherein the first direction intersects the second direction. Specifically, the first direction is the X-axis direction, and the second direction is the Y-axis direction.

[0032] The first correction components 31 are arranged on opposite sides of the film removal station, and the first correction components 31 are used to correct the workpiece 50 in the first direction. The second correction components 32 are arranged on opposite sides of the film removal station, and the second correction components 32 are used to correct the workpiece 50 in the second direction.

[0033] The plurality of second correction components 32 are divided into at least one middle correction component 321 and at least two end correction components 322. The end correction components 322 are respectively arranged at the two ends of the two film removal stations, and the middle correction component 321 is arranged between the two film removal stations. The middle correction component 321, the end correction component 322 and the first correction component 31 all include a correction moving module 311 and a limiting part 312 arranged on the correction moving module.

[0034] In the intermediate correction assembly 321, the correction moving module 311 drives the stopper 312 to move back and forth between the two film removal stations. At this time, in the Y-axis direction, the two film removal stations share the correction moving module 311 and the stopper 312, thereby reducing costs.

[0035] The top surface height of the stopper 312 exceeds the top surface height of the support assembly 23. When the conveyor line lifting assembly 22 drives the feeding conveyor line 21 to rise to the highest position, the top surface height of the stopper 312 is lower than the top surface height of the feeding conveyor line 21. At this time, the workpiece 60 contacts the feeding conveyor line 21 and is conveyed by it. When the workpiece 60 is transmitted to the film removal station, the feeding conveyor line 21 drops and is lower than the top surface height of the support assembly 23. At this time, the top surface height of the stopper 312 exceeds the top surface height of the support assembly 23 to facilitate correction.

[0036] Please refer to Figure 5 The correction moving module 311 includes a reciprocating correction slide 3111, a guide rail is provided on the correction slide 3111, a slider 3112 is provided on the guide rail, and the limiter 312 is provided on the slider 3112. The limiter 312 is specifically a wheel. It also includes a stopper block 3113 provided at one end of the guide rail, and the stopper block 3113 is used to limit the slider 3112 from moving out of the guide rail. The stopper block 3113 is preferably an elastic member such as a spring. During correction, the correction slide slides, driving the slider 3112 and the limiter 312 to move, the limiter 312 moves and abuts against the workpiece 60, and the correction slide 3111 continues to move, thereby correcting the workpiece. The slider 3112 and the stopper block 3113 cooperate to provide buffering to reduce the impact force.

[0037] Please refer to Figure 3 In this solution, the first correction assembly 31 is provided with four groups, of which two groups are arranged on opposite sides of one film removal station, and the other two groups are arranged on opposite sides of another film removal station. The second correction assembly 32 is provided with six groups, of which two groups are provided with middle correction assembly 321, and four groups are provided with end correction assembly 322. Two groups of middle correction assembly 321 are provided between two film removal stations, two groups of end correction assembly 322 are provided on the side of one film removal station away from the middle moving module, and the remaining two groups of end correction assembly 322 are provided on the side of another film removal station away from the middle moving module.

[0038] In the above scheme, an induction switch is provided at the film removal station, and the induction switch is used to determine whether the workpiece 50 has moved to the film removal station.

[0039] Please refer to Figure 7The laser film removal device 42 includes a Z-axis lifting module 421, a beam expander, a reflector group, a field lens, a galvanometer 424, and an industrial camera assembly 423. The Z-axis lifting module drives the beam expander, the reflector group, the field lens, the galvanometer 424, and the industrial camera assembly 423 to rise and fall. The laser film removal device 42 also includes a dust extraction assembly 422, which is used to absorb dust generated during laser film removal.

[0040] After the correction mechanism 30 mechanically corrects the glass workpiece 50, the horizontal moving module 41 moves the laser film removal device 42 to the top of the glass workpiece 50, and the industrial camera component 423 takes a picture of the glass, compares the offset of the glass, and calculates and compares it internally in the computer to compensate for the distance between the pattern to be film removed and the actual glass. After the compensation position is determined, the industrial computer controls the laser film removal device 42 to emit light, and the dust extraction component 422 is turned on to absorb the dust generated by the laser film removal. At the same time, the horizontal moving module 41 is also moving, adjusting the position distance at any time, and the galvanometer 424 gives out the graphics set in advance in sequence. It takes about 23 seconds to complete one cycle, and the film removal pattern is completed. The horizontal moving module 41 moves to another glass workpiece 50 at the film removal station and cycles in sequence.

[0041] Please refer to Figure 1 and Figure 2 The horizontal moving module 41 includes two groups of X-axis moving modules 411 arranged on both sides of the feeding mechanism 20 and a Y-axis moving module 412 arranged on the two groups of X-axis moving modules 411, and the laser film removal device 42 is arranged on the Y-axis moving module 412. The horizontal moving module 41 also includes a marble platform, and the X-axis moving module 411 and the Y-axis moving module 412 are installed on the marble platform. At the same time, the X-axis moving module 411 and the Y-axis moving module 412 use linear motors as power sources, thereby greatly improving the accuracy and speed when stationary and moving. The speed of the linear motor is generally between 3m / s-6m / s, the acceleration can reach 1G-5G, and the repeatability positioning accuracy is 0.05 / 50mm; the marble platform 00 level 1000mm*100*40 can reach an accuracy of 3 microns.

[0042] The feeding conveyor line 21 includes a synchronous belt, which is a double-layered arrangement, including a light-transmitting layer arranged on the outer layer and a light-impermeable layer arranged on the inner layer, and the inner and outer layers are bonded. When part of the laser irradiates the synchronous belt, the laser irradiates the light-impermeable layer of the inner layer through the light-transmitting layer of the outer layer, and at this time, dust pollutants are generated between the outer layer and the inner layer, thereby avoiding the contamination of the glass by the dust pollutants. Specifically, the outer layer of the synchronous belt is made of white or transparent material, and the inner layer is made of green material.

[0043] The horizontal multi-station film removal equipment disclosed in the present invention can greatly improve the film removal efficiency because one glass workpiece 50 can be discharged, fed, and corrected simultaneously while the other glass workpiece 50 is undergoing film removal processing. At the same time, when the equipment is laser film removal, the glass workpiece 50 is supported by the support assembly 23, which makes it easier to ensure the positioning height, and at this time, the feeding conveyor line 21 is far away from the focus of the laser, avoiding damage to the feeding conveyor line 21.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
