Description

Technical Field

[0001] This utility model relates to the technical field of tempered glass film die-cutting, specifically to a tempered glass film die-cutting device. Background Technology

[0002] Tempered glass die-cutting is a process used for protecting mobile phone screens. It involves cutting, grinding, drilling, and cleaning ordinary glass, then tempering it and finally bonding it with AB glue. Its features include high hardness, scratch resistance, shock absorption, ultra-thin design, and automatic adhesion, effectively preventing mobile phone screens from cracking and scratching. The production process is complex and requires strict standards, necessitating a cleanroom environment to ensure product quality.

[0003] According to Chinese Patent No. CN216998178U, a tempered film die-cutting device includes: a worktable; a support frame, the support frame being fixedly connected to the surface of the worktable, a cylinder being fixedly connected to the top of the support frame, a mounting plate being fixedly connected to the telescopic end of the cylinder, a frame-shaped cutter being fixedly connected to the bottom of the mounting plate, a toothed rod being inserted through the mounting plate, a second spring being sleeved on the surface of the toothed rod, a first gear meshing on one side of the toothed rod, a second gear meshing on one side of the first gear, a toothed plate meshing on one side of the second gear, and a push plate being fixedly connected to the bottom end of the toothed plate through the mounting plate and through the frame-shaped cutter.

[0004] In the above solution, an electric push rod is used to push the die-cut tempered glass film into the collection box. However, this solution still has the following drawbacks: when the electric push rod pushes the die-cut tempered glass film into the collection box, the tempered glass film may collide with each other and break, which reduces the safety of the tempered glass film. Utility Model Content

[0005] The purpose of this invention is to provide a die-cutting device for tempered glass film, in order to solve the problem that when the electric push rod pushes the die-cut tempered glass film into the collection frame, the tempered glass film may collide with each other and break, which reduces the safety of the tempered glass film.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a die-cutting device for tempered glass film, comprising a mounting plate, a mounting folding plate fixed on the top surface of the mounting plate, a hydraulic cylinder fixed on the top surface of the mounting folding plate, a telescopic rod of the hydraulic cylinder slidably inserted into the mounting folding plate, a lifting plate slidably disposed inside the mounting folding plate, the top surface of the lifting plate being fixed to the bottom end of the telescopic rod of the hydraulic cylinder, a die-cutting template detachably disposed on the bottom surface of the lifting plate, an electric push rod fixed on the top surface of the mounting plate, a push plate fixed at one end of the telescopic rod of the electric push rod, two supporting folding plates fixed on the bottom surface of the mounting plate, a storage frame slidably disposed between the two supporting folding plates, and a protective pad fixed inside the storage frame.

[0007] Preferably, omnidirectional wheels are fixed at the four corners of the bottom surface of the storage frame, and a blocking plate is fixed on the top surface of the horizontal folding surface of the support folding plate.

[0008] Preferably, limit openings are provided on both sides of the mounting plate, and sliding plates are fixed on both sides of the lifting plate, with the sliding plates and limit openings being slidably configured.

[0009] Preferably, a sliding rod is fixed to the inner top surface of the limiting port, the bottom end of the sliding rod is fixed to the top surface of the mounting plate, the sliding plate and the sliding rod are slidably inserted, a return spring is surrounded on the surface of the sliding rod, one end of the return spring is fixed to the top surface of the mounting plate, and the other end of the return spring is fixed to the bottom surface of the sliding plate.

[0010] Preferably, the top surface of the lifting plate is provided with a plurality of fixing holes, and the top surface of the die-cutting template is fixed with a plurality of threaded cylinders, the threaded cylinders being slidably inserted into the fixing holes, and the internal threads of the threaded cylinders being connected with fixing bolts.

[0011] Preferably, a PLC controller is provided on the top surface of the mounting plate, and a mounting groove is provided on one side of the interior of the mounting plate. A pressure sensor is slidably installed inside the mounting groove. A compression spring is fixed to one end of the pressure sensor, and the other end of the compression spring is fixed to one end of the interior of the mounting groove.

[0012] Compared with existing technologies, the tempered film die-cutting device that adopts the above technical solution has the following advantages:

[0013] First, the staff will place the raw material on the top surface of the mounting plate. Then, the staff will activate the hydraulic cylinder. The extension rod of the hydraulic cylinder will push the lifting plate downward and move the die-cutting template downward simultaneously to die-cut the raw material. After the die-cutting is completed, the staff will remove the die-cut frame from the mounting plate. Then, the telescopic rod of the electric push rod will extend, which will move the push plate on the top surface of the mounting plate. During the movement, the die-cut tempered glass film will be pushed down from the top surface of the mounting plate and fall into the storage frame. When the tempered glass film falls into the storage frame, it will first contact the protective pad made of sponge fixed inside the storage frame. Then, the tempered glass film will be guided by the slope on one side of the protective pad to slide down to the bottom of the storage frame. The tempered glass film itself and the impact force it receives are relatively small throughout the process, which can protect the die-cut tempered glass film and increase the safety of the tempered glass film.

[0014] 2. When the lifting plate moves downward inside the mounting plate, it will drive the sliding plate to slide downward synchronously inside the limit port. During the downward sliding process, the reset spring is compressed. When the material is die-cut, the hydraulic cylinder stops working and the telescopic rod retracts. At this time, the lifting plate will move upward under the push of the reset spring, which can drive the lifting plate to quickly lift and reset, making it easier to perform the die-cutting operation of the next material, thereby increasing the efficiency of die-cutting.

[0015] 3. When die-cutting different styles of tempered glass film, the operator can first unscrew the fixing bolts from the inside of the threaded cylinder, and then remove the currently installed die-cutting template and replace it with the corresponding style die-cutting template. This increases the diversity of die-cutting processes. During the die-cutting process, the downward-moving lifting plate will push the pressure sensor towards the inside of the mounting slot. As the lifting plate continues to move downward, the pressure sensor will be pushed back by the compressed spring. After sensing the pressure, the pressure sensor will send a signal to the PLC controller. After receiving the signal, the PLC controller will start working. When the raw material is die-cut, the lifting plate moves upward and pushes the pressure sensor again during the upward movement. At this time, the pressure sensor will send a signal to the PLC controller again. After receiving the signal, the PLC controller will control the electric push rod to push the die-cut tempered glass film out of the top surface of the mounting plate, thus increasing the automation of raw material die-cutting.

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1-3 As shown, a die-cutting device for tempered glass film includes a mounting plate 1, a mounting folding plate 2 fixed on the top surface of the mounting plate 1, a hydraulic cylinder 3 fixed on the top surface of the mounting folding plate 2, a telescopic rod of the hydraulic cylinder 3 slidably inserted into the mounting folding plate 2, a lifting plate 4 slidably arranged inside the mounting folding plate 2, the top surface of the lifting plate 4 being fixed to the bottom end of the telescopic rod of the hydraulic cylinder 3, a die-cutting template 5 detachably arranged on the bottom surface of the lifting plate 4, an electric push rod 6 fixed on the top surface of the mounting plate 1, a push plate 7 fixed at one end of the telescopic rod of the electric push rod 6, two supporting folding plates 8 fixed on the bottom surface of the mounting plate 1, a storage frame 9 slidably arranged between the two supporting folding plates 8, a protective pad 10 fixed inside the storage frame 9, casters 11 fixed at the four corners of the bottom surface of the storage frame 9, and a blocking plate 12 fixed on the top surface of the horizontal folding surface of the supporting folding plate 8.

[0024] In use, the operator first places the raw material on the top surface of the mounting plate 1. Then, the operator activates the hydraulic cylinder 3. The extension rod of the hydraulic cylinder 3 pushes the lifting plate 4 downward, and drives the die-cutting template 5 to move down synchronously to die-cut the raw material. After die-cutting, the operator removes the die-cut frame from the mounting plate 1. Then, the telescopic rod of the electric push rod 6 extends, which drives the push plate 7 to move on the top surface of the mounting plate 1. During the movement, the die-cut tempered glass film is pushed down from the top surface of the mounting plate 1 and falls into the storage frame 9. When the tempered glass film falls into the storage frame 9, it first contacts the protective pad 10 made of sponge fixed inside the storage frame 9. Then, the tempered glass film is guided by the slope on one side of the protective pad 10 to slide down to the bottom of the storage frame 9. The tempered glass film itself and the impact force it receives are relatively small throughout the process, which can protect the die-cut tempered glass film and increase its safety.

[0025] like Figure 2 and Figure 3 As shown, limit openings 13 are respectively opened on both sides of the mounting plate 2, and sliding plates 14 are respectively fixed on both sides of the lifting plate 4. The sliding plates 14 and the limit openings 13 are slidably arranged. A sliding rod 15 is fixed on the inner top surface of the limit opening 13. The bottom end of the sliding rod 15 is fixed to the top surface of the mounting plate 1. The sliding plate 14 and the sliding rod 15 are slidably inserted. A return spring 16 is surrounded on the surface of the sliding rod 15. One end of the return spring 16 is fixed to the top surface of the mounting plate 1, and the other end of the return spring 16 is fixed to the bottom surface of the sliding plate 14.

[0026] In use, when the lifting plate 4 moves downward inside the mounting plate 2, it will drive the sliding plate 14 to slide downward synchronously inside the limit port 13. During the downward sliding process, the return spring 16 is compressed. When the material is die-cut, the hydraulic cylinder 3 stops working and the telescopic rod retracts. At this time, the lifting plate 4 will move upward under the push of the return spring 16, which can drive the lifting plate 4 to quickly lift and reset, making it easier to carry out the die-cutting operation of the next material, thereby increasing the die-cutting efficiency.

[0027] like Figure 2 , Figure 4 and Figure 5 As shown, the top surface of the lifting plate 4 has several fixing holes 18, and the top surface of the die-cutting template 5 has several threaded cylinders 17 fixed thereon. The threaded cylinders 17 are slidably inserted into the fixing holes 18. The threaded cylinders 17 are internally connected to fixing bolts 19. The top surface of the mounting plate 2 is equipped with a PLC controller, which is a Siemens 6ES7511-1AK02-0AB0. The mounting plate 2 has an installation groove 20 on one side inside. The installation groove 20 is slidably equipped with a pressure sensor 21, which is an MPX5100. One end of the pressure sensor 21 is fixed with a compression spring 22, and the other end of the compression spring 22 is fixed to one end inside the installation groove 20. The PLC controller is electrically connected to the pressure sensor 21 and the electric push rod 6.

[0028] In use, when die-cutting different styles of tempered glass film, the operator can first unscrew the fixing bolt 19 from the inside of the threaded cylinder 17, and then remove the currently installed die-cutting template 5 and replace it with a corresponding style of die-cutting template 5, which can increase the diversity of die-cutting processes. During the die-cutting process of the raw material, the downward-moving lifting plate 4 will push the pressure sensor 21 towards the inside of the mounting groove 20. When the lifting plate 4 continues to move downward, the pressure sensor 21 will be pushed back by the compressed compression spring 22. After sensing the pressure, the pressure sensor 21 will send a signal to the PLC controller. After receiving the signal, the PLC controller will start working. When the raw material is die-cut, the lifting plate 4 moves upward and pushes the pressure sensor 21 again during the upward movement. At this time, the pressure sensor 21 will send a signal to the PLC controller again. After receiving the signal, the PLC controller will control the electric push rod 6 to work and push the die-cut tempered glass film out of the top surface of the mounting plate 1, which can increase the automation of the raw material die-cutting.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
