Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone protective films, in particular to a mobile phone protective film heat bending device. Background Art

[0002] A mobile phone protective film is a thin film material used to protect the screen or other parts of a mobile phone. It can prevent scratches, bumps and wear and tear during daily use. This protective film is usually made of transparent plastic or glass materials, which can effectively absorb impact and prevent the screen from breaking. At the same time, they can also reduce the adhesion of fingerprints and oil stains, keeping the screen clean. Some advanced mobile phone protective films also have anti-blue light, anti-ultraviolet and other properties to protect the user's eyesight. In addition, there are anti-peep protective films that can protect the user's personal privacy by adjusting the viewing angle of the screen. In general, mobile phone protective films are an important tool to protect the mobile phone screen, which can extend the service life of the mobile phone, maintain the clarity of the screen and enhance the user experience.

[0003] The cam is provided with a plurality of guide rails, the guide rails being connected to the bottom mold by bolts in the middle of the fixing plate, the middle position of the bottom mold being provided with a groove, and the bottom mold being slidably connected to the guide rails by the groove. A support rod is welded on one side of the fixing plate, the cover plate is located above the bottom mold, and the upper end of the support rod passes through the cover plate, and the end of the support rod is threadedly connected to a limit plate. The utility model limits the cover plate by adding a support rod to facilitate guiding when the cover plate is pressed down to fit the bottom mold. The spring connected to the cover plate can provide an elastic force to press the cover plate down, maintain the cover plate pressed on the bottom mold, and the guide rail is used to cooperate with the movable bottom mold, so as to facilitate the cooperation in sending the bottom mold into the hot bending machine for hot forming processing. When the cover plate is pressed on the bottom mold under the elastic force of the spring, the baffle on the side of the cover plate can cooperate to clamp the bottom mold to prevent the bottom mold from loosening, thereby ensuring the stability of the hot forming.

[0004] However, during the actual production and processing process, the applicant found that when the mobile phone protective film is hot-bent, a large amount of heat will be generated on the surrounding metal parts. Therefore, when the hot bending work is completed, if the operator accidentally touches the surrounding metal structure when the staff takes out the mobile phone protective film, it will cause harm to himself and affect the production efficiency of the equipment. For this reason, this application provides a mobile phone protective film hot bending device. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and provide a mobile phone protective film heat bending device.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a mobile phone protective film hot bending device, comprising a shell, a die assembly is provided on the shell, the die assembly comprises a base plate, a first mold is provided on the base plate, a placement groove is provided in the base plate, a spring is fixedly connected in the placement groove, a spring is fixedly connected to the top of the spring, a slot is provided on the spring plate, a slot hole is provided on the first mold, a slot hole adapted to the spring plate is provided, a limiting block is fixedly connected to the four ends of the first mold, a limiting rod is fixedly connected to the four ends of the base plate, and a slot hole adapted to the limiting rod is provided on the first mold.

[0007] As a preferred embodiment, the shell is fixedly connected to a support rod, the support rod is movably connected to a second slider, the second slider is fixedly connected to the support plate through a pressure plate, a hot bending component is provided on the support plate, and the hot bending component includes a hydraulic cylinder, a hydraulic lifting and retraction rod is passed through the bottom end of the hydraulic cylinder, and buffer pads are fixedly connected to both ends of the hydraulic lifting and retraction rod, a fixed block is fixedly connected to the bottom end of the pressure plate, a heating plate is provided at the bottom end of the fixed block, a clamping block is fixedly connected to the heating plate, a clamping slot adapted to the clamping block is provided on the fixed block, a second mold is movably connected to the bottom end of the heating plate, and a shock-absorbing plate is fixedly connected to the pressure plate.

[0008] The technical effect of adopting the above-mentioned further scheme is: the mobile phone protective film that needs to be hot-bent is placed in the first mold, and the hydraulic cylinder is started at this time. The hydraulic cylinder pushes the hydraulic lifting and retracting rod to extend and retract downward, and the hydraulic retracting rod drives the buffer pad and the pressure plate to press downward. Because the bottom end of the pressure plate is fixedly connected to the fixed block and the fixed structure on the fixed block, when the second mold contacts the mobile phone protective film that needs to be hot-bent, the heating effect of the heating plate heats the mobile phone protective film that needs to be hot-bent, so that the mobile phone protective film that needs to be hot-bent begins to soften due to the heat. As the hot bending component continues to press downward, the mobile phone protective film also begins to deform until it completely fits the shape in the first mold.

[0009] As a preferred embodiment, a cooling assembly is provided on the outer shell, and the cooling assembly includes a fixed base, a blower is fixedly connected to the top end of the fixed base, a first slider is fixedly connected to the bottom end of the fixed base, and a slide groove adapted to the first slider is opened on the outer shell.

[0010] The technical effect of adopting the above-mentioned further scheme is: after the hot bending work is completed, the blower is turned on, and cold air is blown out from the blower towards the protective film that has been ejected, quickly cooling the protective film that is still in a high temperature state, and accelerating the speed of the protective film forming. The limit block can prevent the protective film from being blown off by the wind during the cooling process, causing damage to the protective film and reducing the production efficiency of the device.

[0011] As a preferred embodiment, a maintenance cabinet door is provided on one end of the shell, heat dissipation holes are opened on the other three sides of the shell, and an operating table is provided on the end of the shell close to the maintenance cabinet door.

[0012] The technical effect of adopting the above further solution is that when maintenance is needed, the maintenance cabinet door can be directly opened to repair the equipment, making the inspection and maintenance work more convenient. During the operation of the equipment, a large amount of heat is often generated. The heat dissipation holes can effectively remove the stored heat in the casing and extend the service life of the equipment.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] By setting up a die assembly, the hot bending template of the mobile phone protective film is aligned with the limit rod and placed on the bottom plate for fixation. After the hydraulic cylinder completes the hot bending work on the mobile phone protective film, the hydraulic cylinder starts to pull upwards. Under the elastic force of the spring, the spring plate and the mobile phone protective film on the spring plate are ejected upwards, allowing the operator to safely remove the protective film away from the heat source, effectively preventing the risk of burns to personnel and improving the safety and convenience of the operation.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 5 As shown, this embodiment provides a technical solution: a mobile phone protective film hot bending device, including a shell 1, a die assembly 2 is provided on the shell 1, the die assembly 2 includes a bottom plate 21, a first mold 22 is provided on the bottom plate 21, a placement groove 26 is provided in the bottom plate 21, a spring 25 is fixedly connected to the placement groove 26, a spring 25 is fixedly connected to the top of the spring 25, a slot is provided on the spring 24, a slot is provided on the first mold 22, a slot hole is provided on the first mold 22 that is adapted to the spring 24, the four ends of the first mold 22 are fixedly connected to the limiting block 23, the four ends of the bottom plate 21 are fixed A limit rod 27 is fixedly connected, and a slot hole that is compatible with the limit rod 27 is opened on the first mold 22. The hot bending template of the mobile phone protective film is aligned with the limit rod 27 and fixed on the bottom plate 21. After the hydraulic cylinder 31 completes the hot bending work on the mobile phone protective film, the hydraulic cylinder 31 starts to pull upward. Under the elastic force of the spring 25, the spring plate 24 and the mobile phone protective film on the spring plate 24 are ejected upward, allowing the operator to safely remove the protective film away from the heat source, effectively preventing the risk of burns to personnel and improving the safety and convenience of the operation.

[0028] A step further, such as Figures 1-4As shown: the shell 1 is fixedly connected to a support rod 11, the support rod 11 is movably connected to a second slider 12, the second slider 12 is fixedly connected to the support plate 7 through a pressing plate 5, a hot bending assembly 3 is provided on the support plate 7, the hot bending assembly 3 includes a hydraulic cylinder 31, the bottom end of the hydraulic cylinder 31 is penetrated by a hydraulic telescopic rod 33, both ends of the hydraulic telescopic rod 33 are fixedly connected to a buffer pad 32, the bottom end of the pressing plate 5 is fixedly connected to a fixed block 34, the bottom end of the fixed block 34 is provided with a heating plate 35, the heating plate 35 is fixedly connected to a card block 37, the fixed block 34 is provided with a card slot 38 adapted to the card block 37, the bottom end of the heating plate 35 is movably connected to a second mold 36, the pressing plate 5 is fixedly connected to A shock-absorbing plate 6 is connected, and a mobile phone protective film that needs to be hot-bent is placed in the first mold 22. At this time, the hydraulic cylinder 31 is started, and the hydraulic cylinder 31 pushes the hydraulic lifting and retracting rod 33 to extend and retract downward. The hydraulic retracting rod 33 drives the buffer pad 32 and the pressing plate 5 to press downward. Because the bottom end of the pressing plate 5 is fixedly connected to the fixed block 34 and the fixed structure on the fixed block 34, when the second mold 36 contacts the mobile phone protective film that needs to be hot-bent, the heating effect of the heating plate 35 heats the mobile phone protective film that needs to be hot-bent, so that the mobile phone protective film that needs to be hot-bent begins to soften due to the heat. As the hot bending component 3 continues to press downward, the mobile phone protective film also begins to deform until it completely fits the shape in the first mold 22.

[0029] The above solutions still have the problem that the high temperature environment caused by hot bending is not easy to cool and remove, such as Figure 2 As shown: In this solution, a cooling component 4 is provided on the shell 1, and the cooling component 4 includes a fixed base 42, a blower 41 is fixedly connected to the top of the fixed base 42, and a first slider 43 is fixedly connected to the bottom of the fixed base 42. A slide groove adapted to the first slider 43 is provided on the shell 1. After the hot bending work is completed, the blower 41 is turned on, and cold air is blown out from the blower 41 to the protective film that has been ejected, quickly cooling the protective film that is still in a high temperature state, and accelerating the speed of the protective film forming. The limit block 23 can prevent the protective film from being blown off by the wind during the cooling process, causing damage to the protective film, thereby reducing the production efficiency of the device.

[0030] The above solutions also have the problem of equipment aging caused by heating during use, such as Figure 1-Figure 2 As shown: In this solution, a maintenance cabinet door 10 is provided on one end of the shell 1, and heat dissipation holes 8 are opened on the other three sides of the shell 1. An operating table 9 is provided on the end of the shell 1 close to the maintenance cabinet door 10. When maintenance is needed, the maintenance cabinet door 10 can be directly opened to repair the equipment, making the inspection and maintenance work more convenient. During the operation of the equipment, a large amount of heat is often generated. The heat dissipation holes 8 can effectively remove the stored heat in the shell 1 and extend the service life of the equipment.

[0031] Working principle:

[0032] like Figure 1-5As shown:

[0033] During use: align the hot bending template of the mobile phone protective film with the limit rod 27 and place it on the bottom plate 21 for fixing. Place the mobile phone protective film that needs to be hot bent in the first mold 22. At this time, start the hydraulic cylinder 31. The hydraulic cylinder 31 pushes the hydraulic lifting and retracting rod 33 to retract downward. The hydraulic lifting and retracting rod 33 drives the buffer pad 32 and the pressing plate 5 to press downward. Because the bottom end of the pressing plate 5 is fixedly connected to the fixed block 34 and the fixed structure on the fixed block 34, when the second mold 36 contacts the mobile phone protective film that needs to be hot bent, the heating effect of the heating plate 35 heats the mobile phone protective film that needs to be hot bent, so that the mobile phone protective film that needs to be hot bent begins to soften due to the heat. As the hot bending component 3 is continuously pressed downward, the mobile phone protective film also begins to deform until it is completely fitted with the first mold 36. The shape in a mold 22, at this time the hydraulic cylinder 31 stops pressing down and starts to pull up, and under the elastic force of the spring 25, the spring plate 24 and the mobile phone protective film on the spring plate 24 are popped up, so that the staff can stay away from the heat source and safely remove the protective film. After the hot bending work is completed, turn on the blower 41, and the cold air is blown out from the blower 41 to the protective film that has been ejected, quickly cooling the protective film that is still in a high temperature state, and accelerating the speed of forming the protective film. The limit block 23 can prevent the protective film from being blown off by the wind during the cooling process, causing damage to the protective film, and reducing the production efficiency of the device. The purpose of opening the ventilation holes on the spring plate 24 is also to share the thrust of the blower 41 on the protective film and enhance the stability of the protective film on the spring plate 24.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
