Description

Technical Field

[0001] The utility model relates to the field of film-coated plate processing equipment, in particular to a film-cutting device. Background Art

[0002] After processing, the processed boards are usually coated to prevent dust and water. When cutting, the protective film should be separated from the board to facilitate the subsequent crushing process. Traditionally, workers usually scratch the surface of the material and then tear it off. Since the force of manual scratching is difficult to control, it will cause scratches on the board, and the labor intensity is high and the work efficiency is low.

[0003] In response to the above problems, a Chinese invention patent with patent number CN201810959259.7 (publication number CN109051144A) in the prior art discloses a film striping machine, in which an automatic loading mechanism transfers the outer shell plate from one end of the frame to the conveyor belt for forward transportation. When the outer shell plate passes under the transverse film striping assembly, the transverse film striping assembly scratches two scratches on the top of the outer shell plate. When the outer shell plate is transported to the side of the longitudinal film striping assembly, the longitudinal film striping assembly scratches two scratches on the top of the outer shell plate that are perpendicular to the scratches made by the transverse film striping assembly. The automatic discharging mechanism then pushes the processed outer shell plate out of the frame. The film striping machine realizes fully automatic film striping and reduces the labor intensity of workers. However, the four-way horizontal and vertical film striping method of the film striping machine needs to pass through the full length and width of the plate. If the film striping depth is too large, the film striping method will leave a whole scratch on the surface of the plate, seriously affecting the quality of the plate. Utility Model Content

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] like Figures 1 to 11 The film-scratching device of this embodiment is mainly used for film-scratching material 1a. When the processing surface of material 1a is large, the film-scratching device must provide users with a film-scratching device that does not leave a scratch 1b that crosses the processing surface after film-scratching material 1a, so as not to affect the quality of material 1a. Therefore, it is beneficial to provide a film-scratching device that does not scratch the entire plate, that is, only films along a fixed track. The structure of the film-scratching device will be described below:

[0047] See also Figures 1 to 6The film stripping device is used to process the material 1a from a state before film stripping to a state after film stripping, and leave a scratch 1b on the protective film of the material 1a to facilitate tearing off. The film stripping device includes a frame 1, a material discharge platform 2, and a first film stripping mechanism 3, wherein the material discharge platform 2 is arranged on the aforementioned frame 1 for placing the coated material 1a, and the first film stripping mechanism 3 is movably arranged on the aforementioned frame 1 to cut the coated film. The first film stripping mechanism 3 includes a first driving source 31 arranged on the frame 1, a first slide rail 32 arranged on the frame 1, a first slider 33, a track guide plate 34, a push plate 35, a first film stripping mechanism 3, and a first film stripping mechanism 3. The first slide block 33 has a power output end connected to the first driving source 31 and can move back and forth on the first slide rail 32; the track guide plate 34 is arranged on the frame 1 and is located above the material discharging platform 2, and the track guide plate 34 has a film-scratching track hole 341; the push plate 35 is connected to the first slide block 33 and can move back and forth with the first slide block 33, and the push plate 35 has an inclined guide hole 351; the first film-scratching member 36 is arranged through the aforementioned film-scratching track hole 341 and the guide hole 351 and is gap-matched with the aforementioned film-scratching track hole 341 and the guide hole 351. The first slide rail 32 is arranged in parallel with two, distributed on both sides of the track guide plate 34, and the first slide block 33 is slidably matched with the two first slide rails 32.

[0048] The push plate 35 of this embodiment is located above the track guide plate 34, the first driving source 31 is a cylinder, and the first film-scraping member 36 is an electric soldering iron.

[0049] See also Figure 7 The first film stripping member 36 is elastically arranged to penetrate the film stripping track hole 341 and the guide hole 351. When processing a material 1a with a relatively large thickness, the first film stripping member 36 can elastically adjust the height of the lower end, so that the first film stripping member 36 can stop moving without directly interfering with the material 1a, so that the first film stripping mechanism 3 can film and cut materials 1a of different thicknesses.

[0050] The first film stripping member 36 is sleeved with a first spring 37, which always forces the first film stripping member 36 to maintain a tendency to approach the material discharging platform 2. The upper end of the first spring 37 abuts against the lower end surface of the track guide plate 34, and the lower end of the first spring 37 abuts against the step portion 361 of the first film stripping member 36.

[0051] See also Figure 8The film stripping device also includes a second film stripping mechanism 4, which includes a second driving source 41 arranged on the frame 1, a second slide rail 42 arranged on the frame 1, a second slider 43, a connecting plate 44, and a second film stripping member 45, wherein the power output end of the second slider 43 is connected to the aforementioned second driving source 41 and can move back and forth on the second slide rail 42; the connecting plate 44 is connected to the second slider 43 and can move back and forth with the second slider 43; the second film stripping member 45 is arranged on the connecting plate 44, and the second film stripping mechanism 4 can draw another scratch 1b on the material 1a, and subsequent workers can tear the film along the two scratches 1b at the same time, shortening the time of subsequent film tearing operations. The second film stripping mechanism 4 is provided with two groups, one on the left and one on the right; the two groups of electric soldering irons arranged in parallel with the first film stripping mechanism 3 and the second film stripping mechanism 4 perform film stripping on both sides at the same time to improve production efficiency.

[0052] The second film-scratching member 45 is elastically arranged on the connecting plate 44, and is sleeved with a second spring 46, which always forces the second film-scratching member 45 to maintain a tendency to approach the material discharging platform 2. The middle part of the second film-scratching member 45 partially protrudes outward to form a step-like structure, and the lower end of the second spring 46 abuts against the step-like structure.

[0053] The frame 1 is provided with a control box and a switch button connected to the control box, and the control output end of the control box is connected to the first driving source 31. The setting of the switch button and the control box improves the automation of the film stripping device and facilitates the operation of the user. The control output end of the control box is also connected to the second driving source 41.

[0054] See also Fig. 9 , the material discharging platform 2 is provided with a pad 21 and a plurality of positioning blocks 22. The pad 21 is used to place the material 1a, and the positioning blocks 22 are located on the side of the pad 21 and are used to limit the edge of the material 1a. The setting of the positioning blocks 22 limits the overall position of the material 1a on the material discharging platform 2, so that the material 1a will not move randomly on the material discharging platform 2 during the film stripping process, in order to ensure that the material 1a can be accurately and effectively placed at a certain position on the frame during the film stripping process, so as to achieve the dimensional accuracy and shape consistency of the film stripping parts. At the same time, since the electric soldering iron is placed below the product surface after the film stripping is completed, the positioning block 22 is located below the second film stripping member 45 to support the electric soldering iron, and can be used to temporarily put the electric soldering iron aside to prevent interference when the film stripping is performed again.

[0055] At least one positioning block 22 has a waist-shaped hole 221, and a bolt 222 is disposed in the waist-shaped hole 221 to adjust the position of the positioning block 22 on the material discharging platform 2. The user can position materials 1a of different lengths and widths by adjusting the position of the positioning block 22, so that the material discharging platform 2 can adapt to materials 1a of different sizes.

[0056] The film stripping process of the film stripping device for material 1a is as follows:

[0057] 1) Positioning: First, the user determines the installation position of the positioning block 22 by measuring and calculating the size, and uses the bolt 222 to tighten and determine the positioning position to ensure the size accuracy and shape consistency. After the tightening is completed, the film stripping device before the film stripping is as follows Fig.10 As shown, the state of material 1a before film cutting is as follows Figure 1 As shown;

[0058] 2) Film stripping: After the user control box is connected to the air source and the power supply, the material 1a is placed inside the positioning block 22, and the user presses the switch button to start the first driving source 31 and the second driving source 41 at the same time. The first driving source 31 and the second driving source 41 respectively drive the first film stripping member 36 and the second film stripping member 45 to perform the film stripping operation; wherein the first film stripping member 36 strips the film along the film stripping track hole 341, and the second film stripping member 45 moves along the setting direction parallel to the second slide rail 42. During the film stripping process, the first spring 37 and the second spring 46 will have a pre-stressed state, and pressure is applied through this pre-stressed state to strip the material 1a;

[0059] 3) Remove the material 1a: When the first driving source 31 pushes the first film stripping member 36 to the end of the film stripping track hole 341, and the second driving source 41 pushes the second film stripping member 45 to the other side of the long side of the material 1a, the film stripping is completed. Fig.11 As shown, the film stripping device is powered off and the material 1a is removed. Figure 2 As shown, at this time, there are three scratches 1b on the material 1a, and the film-cutting process is completed.
