Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone film production, and more specifically, to a cutting device for producing mobile phone anti-peep films. Background Art

[0002] Mobile phone film is an accessory used to protect the mobile phone screen. It can prevent the screen from scratches, impacts and other physical damage. Mobile phone films can be divided into: PET film (polyester film), TPU film (thermoplastic polyurethane film), tempered glass film, anti-peep film, frosted film, high-definition film, antibacterial film and mirror film. Among them, anti-peep film is a screen protector designed specifically for protecting personal privacy. It is mainly used on electronic devices such as smartphones, tablets, and laptops. The main function of this film is to limit the viewing angle, making it difficult for bystanders to see the content on the screen from the side. Only the user in front can clearly see the screen information. Mobile phone films need to be cut during the production process, that is, the glass is cut into a size that matches the mobile phone according to product requirements.

[0003] In the existing mobile phone film cutting process, a large piece of glass is first cut into small pieces, and then the small pieces of glass are finely cut. When cutting small pieces of glass, the glass is placed on a base plate, and a glass cutter is driven to move to draw a crack line on the glass surface. The glass is then manually bent or knocked to break along the scratch. After cutting is completed, the glass is manually removed from the base plate to complete the cutting.

[0004] However, in actual use, after cutting with a glass cutter, the glass still needs to be processed manually. During manual operation, due to the fragility of the glass, the glass is easily subjected to uneven force, resulting in cracks in the glass, affecting the production quality of the mobile phone film. Utility Model Content

[0005] The utility model provides a cutting device for producing mobile phone privacy film, which aims to solve the problem that after the existing glass cutter is used for cutting, the glass still needs to be processed manually. During the manual operation, due to the fragility of the glass, the glass is easily subjected to uneven force, resulting in cracks in the glass, which affects the production quality of the mobile phone film.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cutting device for producing anti-peep film for mobile phones, comprising a frame, a bracket symmetrically provided at the bottom of the frame, a table provided inside the frame, the table used to support glass, a cutting piece provided between the frame and the table, the cutting piece used to cut the glass; the cutting piece comprises a cutting head, the cutting head is located on the top of the table, a hydraulic cylinder is provided on the top of the frame, the output end of the hydraulic cylinder is detachably connected to the cutting head, the hydraulic cylinder is used to control the up and down movement of the cutting head, thereby cutting the glass; the cutting head comprises a cutting frame, a connecting frame is provided on the top of the cutting frame, a pressure block is provided inside the cutting frame, and a plurality of springs are provided between the pressure block and the cutting frame.

[0007] In a preferred embodiment, the output end of the hydraulic cylinder is provided with multiple arc plates, a threaded ring is provided on the outside of the arc plates, a vertical rod is provided on the top of the cutting head, and the multiple arc plates are all located on the outside of the vertical rod. The threaded ring is used to control the opening and closing of the multiple arc plates, thereby loosening or clamping the vertical rod.

[0008] In a preferred embodiment, a boss is embedded in the table top, and the bottom of the boss is detachably connected to the bottom of the table top.

[0009] In a preferred embodiment, a conveying member is provided between the bracket and the frame, and the conveying member is used to move the glass. The conveying member includes a film and a roller. The roller is provided on the bracket, and a motor is provided between the roller and the bracket. The upper surface of the film is located on the boss, and the lower surface of the film is sleeved on the roller. The rotation of the roller controls the rotation of the film, thereby driving the glass and the film to move synchronously.

[0010] In a preferred embodiment, two groups of limiting rods are symmetrically provided inside the frame, and the film is located between the two limiting rods for limiting the edge of the film.

[0011] In a preferred embodiment, an electric heating rod is provided on one side of the roller, and the electric heating rod is used to smooth the surface of the film.

[0012] The beneficial effects of the present invention are:

[0013] The utility model provides a cutting piece and a boss, controls the hydraulic cylinder to drive the cutting head to move, and makes the cutting frame and the pressure block contact with the glass. The cutting head continues to move downward, and the cutting frame and the pressure block generate pressure on the glass. The cutting frame moves downward, and the pressure block moves upward, and the cutting frame and the pressure block form a staggered state. When the cutting frame cuts the glass, the pressure of the pressure block can reduce the impact force generated by the cutting frame on the glass, so that the force on the glass is uniform. The glass formed after cutting is located inside the cutting frame, and the cutting head is moved up. The pressure block can be pushed to rebound by the spring between the pressure block and the cutting frame, and the glass is pushed out from the inside of the cutting frame, thereby completing the cutting of the glass. This process can directly cut the glass into a certain size without the need for manual operation of the glass, thereby improving the efficiency of glass cutting.

[0014] 1. The utility model sets a conveying part, starts the motor to drive the roller to rotate, makes the film rotate synchronously, and drives the glass to move at the same time. In conjunction with the limit rod, it can not only convey the glass, but also limit the film to prevent the film from curling. In conjunction with the electric heating rod, it can heat the film to eliminate the indentation caused by cutting on the film, facilitate the reuse of the film, and reduce the number of replacements.

DETAILED DESCRIPTION

[0023] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual Figures 1 to 7A cutting device for producing anti-peep film for mobile phones includes a frame 1, a bracket 2 is symmetrically provided at the bottom of the frame 1, a table 3 is provided inside the frame 1, the table 3 is used to support glass, a cutting piece 4 is provided between the frame 1 and the table 3, and the cutting piece 4 is used to cut the glass; the cutting piece 4 includes a cutting head 41, the cutting head 41 is located on the top of the table 3, a hydraulic cylinder 42 is provided on the top of the frame 1, the output end of the hydraulic cylinder 42 is detachably connected to the cutting head 41, and the hydraulic cylinder 42 is used to control the up and down movement of the cutting head 41, thereby cutting the glass; the cutting head 41 includes a cutting frame 410, a connecting frame 411 is provided on the top of the cutting frame 410, a pressure block 412 is provided inside the cutting frame 410, and a plurality of springs 413 are provided between the pressure block 412 and the cutting frame 410.

[0025] The cutting frame 410 and the pressing block 412 are in contact with each other, and the glass is squeezed and evenly stressed. When the cutting frame 410 and the pressing block 412 are in an interlaced state, the cut glass is inside the cutting frame 410. When the cutting frame 410 is moved upward, the pressing block 412 is pushed by the spring 413, and the glass is removed from the cutting frame 410, thereby completing the cutting of the glass.

[0026] Because the pressing block 412 squeezes the middle of the glass and the cutting frame 410 cuts the outside of the pressing block 412, the pressure on the middle of the glass can be reduced, the force on the glass is evenly distributed, and the glass is prevented from breaking. In addition, the cutting frame 410 is an integrated structure and can directly cut the glass into shape without the need for manual processing of the glass.

[0027] Furthermore, the output end of the hydraulic cylinder 42 is provided with a plurality of arc plates 43, a threaded ring 44 is sleeved on the outside of the arc plates 43, a vertical rod 45 is provided on the top of the cutting head 41, and the plurality of arc plates 43 are all located on the outside of the vertical rod 45. The threaded ring 44 is used to control the opening and closing of the plurality of arc plates 43, thereby loosening or clamping the vertical rod 45.

[0028] It should be noted that, since different models of mobile phones match mobile phone films of corresponding sizes, the fastening of the curved plate 43 can be released by rotating the threaded ring 44 to separate it from the curved plate 43, so that the curved plate 43 loosens the vertical rod 45, and the cutting head 41 can be pulled to separate the vertical rod 45 from the curved plate 43, so that the cutting head 41 can be quickly replaced. After replacing the cutting heads 41 of different sizes, different models of mobile phone films can be produced, thereby improving production efficiency.

[0029] Further, refer to the instructions attached Figure 2 and Figure 4 A boss 5 is embedded on the table top 3, and the bottom of the boss 5 is detachably connected to the bottom of the table top 3.

[0030] It should be noted that, because the glass is located on the boss 5 and a silicone plate is embedded in the surface of the boss 5, when the cutting head 41 cuts the glass, the pressing block 412 squeezes the middle part of the glass, and the cutting frame 410 continues to move downward to squeeze the silicone plate to achieve cutting of the glass. The cutting frame 410 is embedded in the silicone plate, which can reduce the impact force generated by the cutting frame 410 on the glass during cutting and avoid glass breakage.

[0031] Since the bottom of the boss 5 is connected to the table top 3 by screws, the boss 5 can be directly disassembled and replaced after the silicone plate on the boss 5 has been used for a certain period of time.

[0032] Further, refer to the instructions attached Figure 4 and Figure 5 A conveying member 6 is provided between the bracket 2 and the frame 1. The conveying member 6 is used to move the glass. The conveying member 6 includes a film 61 and a roller 62. The roller 62 is provided on the bracket 2. A motor 63 is provided between the roller 62 and the bracket 2. The upper surface of the film 61 is located on the boss 5, and the lower surface of the film 61 is sleeved on the roller 62. The rotation of the roller 62 controls the rotation of the film 61, thereby driving the glass and the film 61 to move synchronously.

[0033] It should be noted that the motor 63 is started to drive the roller 62 to rotate. Since the outer surface of the roller 62 is provided with ridges, and the ridges are made of silicone, the rotation of the roller 62 drives the ridges to contact the film 61, which can increase the friction between the film 61 and the roller 62, so that the film 61 rotates synchronously.

[0034] Since the glass is placed on the film 61 and the film 61 rotates synchronously, the film 61 is a polyethylene film, which not only plays a buffering role, but also reduces the friction between the glass and the boss 5, so that the glass moves synchronously with the film 61. That is, after the glass cutting is completed, the glass can be directly removed from the table 3, avoiding manual cleaning by the staff and preventing glass fragments from posing a danger to the staff.

[0035] Furthermore, two groups of limiting rods 64 are symmetrically provided inside the frame 1 , and the film 61 is located between the two limiting rods 64 for limiting the edge of the film 61 .

[0036] It should be noted that since the film 61 is a polyethylene film, it has a low hardness and its edges are prone to curling, which affects the normal use of the film 61. Through two sets of limiting rods 64, since the edge of the film 61 is located between the two sets of limiting rods 64, when the film 61 moves with the roller 62, the edge of the film 61 will move on the limiting rod 64, which can limit the edge of the film 61 and make the film 61 move horizontally.

[0037] Furthermore, an electric heating rod 65 is provided on one side of the roller 62 , and the electric heating rod 65 is used to make the surface of the film 61 smooth.

[0038] It should be noted that, because the film 61 is located above the boss 5, and when the cutting head 41 cuts the glass, it squeezes the film 61 and the silicone plate on the boss 5 at the same time, which not only moves the glass but also reduces the impact force on the glass. At the same time, it reduces the pressure of the cutting head 41 on the film 61, reducing the indentation on the film 61.

[0039] The indentation produced by the cutting head 41 on the film 61 can be heated by connecting the electric heating rod 65. When the film 61 rotates onto the electric heating rod 65, the surface of the film 61 can be smoothed, and the film 61 can be reused, reducing the number of times the film 61 needs to be replaced.

[0040] Working principle: First, place the glass on the film 61, start the hydraulic cylinder 42 to drive the cutting head 41 to move downward, so that the pressure block 412 and the cutting frame 410 are in contact with the glass. When the cutting frame 410 continues to move downward, it contacts the glass and generates pressure, and at the same time squeezes the film 61 and the silicone plate on the boss 5, and the pressure block 412 is pressed and moves up along the cutting frame 410, so that the spring 413 is compressed. The elasticity of the spring 413 forms a rebound force on the pressure block 412, so that the pressure block 412 fits the glass. The cut glass is inside the cutting frame 410, and the cutting head 41 is moved upward. The spring 413 pushes the pressure block 412 to move the glass out of the cutting frame 410, thereby realizing glass cutting and reducing the impact force on the glass. The cutting frame 410 is an integrated structure, which can directly cut the glass into shape without the need for manual glass processing.

[0041] Then, the motor 63 is started to drive the roller 62 to rotate, so that the roller 62 drives the film 61 to rotate synchronously, and at the same time drives the glass on the film 61 to move, so that the cut glass can be removed from the table 3 to avoid manual movement. Then, the electric heating rod 65 is started to avoid heating the film 61, so that the indentation generated during cutting of the film 61 can be eliminated, and the film 61 can be reused.

[0042] Since there is a certain gap between the bottom of the film 61 and the table 3 , when the boss 5 is disassembled, the boss 5 can be taken out from the gap between the film 61 and the table 3 without affecting the operation of the film 61 .

[0043] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
