Description
Technical Field
[0001] This utility model relates to the field of observation window film coating, and more particularly to an observation window film cutting device. Background Technology
[0002] The viewing window is a key transparent component on the plastic casing of appliances such as refrigerators and washing machines, serving both display and aesthetic purposes. To protect its surface from scratches and contamination during transportation and installation, it is usually coated with a film before leaving the factory. This protective film effectively isolates external damage, ensuring that the product arrives in the consumer's hands still looking brand new.
[0003] However, at present, this process relies heavily on manual labor, which has some shortcomings: First, manual rolling and cutting by workers is inefficient, and cutting accuracy is difficult to guarantee, easily resulting in problems such as rough edges, deviations, or damage to the window. Second, traditional methods cannot flexibly adapt to window thicknesses, leading to uneven lamination pressure, which can easily produce bubbles or wrinkles, affecting the protective effect and product aesthetics, and hindering production automation and quality consistency. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this invention is to provide a device for cutting the film covering an observation window.
[0005] The following technical solution is adopted: an observation window film cutting device includes a base plate, a rolling assembly is fixedly provided on one side of the top of the base plate, two cutting assemblies are symmetrically fixedly provided at the front and rear of the top of the base plate, and a vacuum clamp is fixedly provided at the top of the base plate, the vacuum clamp being located at the bottom end of the rolling assembly.
[0006] Optionally, the vacuum clamp includes a support plate, which is fixedly mounted on the top of the base plate. Several pneumatic rods are slidably mounted through the top of the support plate. The bottom end of each pneumatic rod is connected to an air vent, and the top end of each pneumatic rod is connected to a suction cup. Several fastening bolts are fixedly mounted on the top of the support plate, and the support plate is fixedly connected to the top of the base plate by the several fastening bolts.
[0007] Optionally, the cutting assembly includes a hydraulic rod, a bracket is fixedly connected to the bottom end of the hydraulic rod, two sliding rods are symmetrically fixed between the two sides of the bracket, a pressure bar is slidably connected between the two sliding rods, a cutter is fixedly provided on one side of the pressure bar, the top end of the pressure bar is fixedly connected to the bottom end of the hydraulic rod, and a pad is fixedly connected to the bottom end of the bracket, the pad being located at the bottom end of the cutter.
[0008] Optionally, two electric push rods are symmetrically fixed at the front and rear ends of the bracket on the side away from the cutter, and a pressure block is connected to the bottom end of the electric push rods.
[0009] Optionally, a window is magnetically attached to the top of the vacuum clamp, and the window is located below the vacuum clamp.
[0010] Optionally, the rolling assembly includes a drive motor, a motor base is fixedly provided on one side of the drive motor, a coupling is fixedly connected to the drive end of the drive motor, a lead screw is fixedly connected to one side of the coupling, and sliding grooves are rotatably connected to both sides of the lead screw.
[0011] Optionally, a guide post is threaded through and connected to the outer wall of the lead screw. The bottom outer wall of the guide post is slidably connected to the inner wall of the slide groove. A pressing cylinder is fixedly connected to the top of the guide post. The telescopic end of the pressing cylinder passes through the top of the guide post and is fixedly connected to a guide block. The outer wall of the guide block is slidably connected to the inner wall of the guide post.
[0012] Optionally, a pressure roller is rotatably connected to one side of the guide block.
[0013] The technical effects that can be achieved by the technical means of this utility model are as follows: (1) In this utility model, by setting up a cutting component and a vacuum clamp, the device realizes the automatic cutting of excess film after lamination. The vacuum clamp uses the negative pressure generated by the suction cup to firmly adsorb the window onto the support plate, ensuring the stability of the working benchmark. The pneumatic rod is internally connected to the air vent and the suction cup. By moving up and down, the height position of the window at the top of the suction cup can be adjusted, making it more practical. The cutting component drives the cutter to make precise cuts through a hydraulic rod. The two work together to completely replace the inefficient and inaccurate manual cutting, making the whole process more convenient and faster. The cut edges are straight and accurate, greatly improving product quality and production efficiency.
[0014] (2) In this utility model, by setting a pressing cylinder and a guide column, the vertical height of the driving roller can be precisely adjusted. This allows the pressing roller to flexibly adjust the pressing stroke according to different thicknesses of the window during operation, thereby always applying a stable and appropriate rolling pressure. This design ensures that windows of various specifications, from thin to thick, can obtain uniform and sufficient rolling pressure, perfectly eliminating air bubbles, and significantly enhancing the equipment's adaptability to different products and processing effect.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] A preferred embodiment of the observation window film cutting device provided by this utility model is, for example... Figures 1 to 5 As shown: An observation window film cutting device includes a base plate 1, a rolling assembly 2 fixedly disposed on one side of the top of the base plate 1, two cutting assemblies 3 symmetrically fixedly disposed at the front and rear of the top of the base plate 1, and a vacuum clamp 5 fixedly disposed at the top of the base plate 1, the vacuum clamp 5 being located at the bottom end of the rolling assembly 2.
[0021] In this embodiment, the vacuum clamp 5 includes a support plate 501, which is fixedly mounted on the top of the base plate 1. A plurality of pneumatic rods 502 are slidably mounted through the top of the support plate 501. The bottom end of each pneumatic rod 502 is connected to an air vent 503, and the top end of each pneumatic rod 502 is connected to a suction cup 504. A plurality of fastening bolts 505 are fixedly mounted on the top of the support plate 501, and the support plate 501 is fixedly connected to the top of the base plate 1 by the plurality of fastening bolts 505.
[0022] With the above scheme, the support plate 501 is the base plate of the vacuum clamp 5, the pneumatic rod 502 is internally connected to the air vent 503 and the suction cup 504. By moving up and down, the height position of the window 4 at the top of the suction cup 504 can be adjusted. The air vent 503 is connected to the inside of the suction cup 504. By evacuating air here, multiple pneumatic rods 502 and several independent suction cups 504 at their tops work together to firmly suction the window 4 at its top.
[0023] In this embodiment, the cutting component 3 includes a hydraulic rod 301, a bracket 302 is fixedly connected to the bottom end of the hydraulic rod 301, two slide rods 306 are symmetrically fixed between the two sides of the bracket 302, a lower pressure strip 303 is slidably connected between the two slide rods 306, a cutter 304 is fixedly provided on one side of the lower pressure strip 303, the top end of the lower pressure strip 303 is fixedly connected to the bottom end of the hydraulic rod 301, and a pad 305 is fixedly connected to the bottom end of the bracket 302, with the pad 305 located at the bottom end of the cutter 304.
[0024] The above solution uses hydraulic rod 301 to drive the lower pressure bar 303 to descend, causing the cutter 304 to descend and contact the top of the pad 305 at the lower end of the bracket 302, thus completing the cutting work. Compared with manual cutting, the operation is simple, accurate and fast.
[0025] In this embodiment, two electric push rods 307 are symmetrically fixed at the front and rear ends of the side of the bracket 302 away from the cutter 304, and a pressure block 308 is connected to the bottom end of the electric push rod 307.
[0026] With the above solution, when the film covers the top of the window 4, the two electric push rods 307 on both sides of the two cutting components 3 fix the four corners of the film and position it to prevent displacement from causing errors in the cutting process, and facilitate subsequent rolling, cutting and other operations.
[0027] In this embodiment, a window 4 is attached to the top of the vacuum clamp 5, and the window 4 is located below the vacuum clamp 5.
[0028] According to the above scheme, window 4 is the object to be processed, that is, the observation window itself that needs to be covered with film, which is the core target of the entire device.
[0029] In this embodiment, the rolling assembly 2 includes a drive motor 201, a motor base 202 is fixedly provided on one side of the drive motor 201, a coupling 209 is fixedly connected to the drive end of the drive motor 201, a lead screw 205 is fixedly connected to one side of the coupling 209, and slide grooves 203 are rotatably connected to both sides of the lead screw 205.
[0030] Through the above scheme, the drive motor 201 drives the coupling 209 to rotate, thereby driving the lead screw 205 to rotate inside the slide groove 203. The drive motor 201 provides power for the displacement of the guide column 208, which facilitates the displacement of the pressure roller 204 at the top of the window 4.
[0031] In this embodiment, a guide post 208 is threaded through and connected to the outer wall of the lead screw 205. The bottom outer wall of the guide post 208 is slidably connected to the inner wall of the slide groove 203. A pressing cylinder 206 is fixedly connected to the top of the guide post 208. The telescopic end of the pressing cylinder 206 passes through the top of the guide post 208 and is fixedly connected to a guide block 207. The outer wall of the guide block 207 is slidably connected to the inner wall of the guide post 208.
[0032] The above scheme utilizes the downward pressure cylinder 206 to drive the guide block 207 to slide on the inner wall of the guide column 208, thereby driving the pressure roller 204 to move up and down to adapt to window bodies 4 of different thicknesses, thus having higher practicality.
[0033] In this embodiment, a pressure roller 204 is rotatably connected to one side of the guide block 207.
[0034] Through the above solution, the pressure roller 204 can apply pressure to adhere the film to the top of the window 4 by directly contacting and rolling it, which can prevent insufficient contact between the film and the top of the window 4 from generating air bubbles and affecting the bonding effect.
[0035] Working principle: When operating and using this utility model, as follows... Figure 1 As shown in the figure, when in use, the window 4 is placed on the support plate 501 of the vacuum clamp 5, the appropriate height is adjusted by the action of the pneumatic rod 502, and air is drawn in through the air vent 503, so that the suction cup 504 generates negative pressure and firmly adsorbs the window 4.
[0036] The film is passed between the two cutting components 3 and positioned at the top of the window 4. Then, the two electric push rods 307 on both sides of the two cutting components 3 fix the four corners of the film to position it and prevent displacement. During film application, the pressure cylinder 206 drives the guide block 207 to slide on the inner wall of the guide post 208, causing the pressure roller 204 to move up and down to accommodate window 4 of different thicknesses. Then, the drive motor 201 drives the coupling 209 to rotate, thereby driving the lead screw 205 to rotate inside the slide groove 203, causing the guide post 208 to slide along the inner wall of the slide groove 203, so that the pressure roller 204 rolls the film at a uniform speed to remove air bubbles.
[0037] After the film is applied, the hydraulic rod 301 drives the lower pressure bar 303 to descend, causing the cutter 304 to descend and contact the top of the pad 305 at the lower end of the bracket 302, thus completing the cutting work.
[0038] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this utility model.
