Description

Technical Field

[0001] The invention relates to the technical field of mobile phone film cutting, and in particular to a mobile phone film cutting and marking mechanism. Background Art

[0002] Mobile phone film, also known as mobile phone screen protector, is a thin film attached to the surface of the mobile phone display. Its main function is to protect the mobile phone screen from scratches, scrapes, oil stains, fingerprints and other damage, and it can also prevent the screen from breaking to a certain extent. With the popularity of smart phones, mobile phone films have also become one of the important products in the mobile phone accessories market. The scribing and cutting of mobile phone films is a customized or special processing technology used to accurately cut mobile phone films into specific shapes or sizes to adapt to different mobile phone models, edge designs or user personalized needs. This technology is usually achieved using laser cutting or high-precision mechanical cutting equipment to ensure that the cutting edges are smooth and accurate without causing additional damage to the mobile phone film. When scribing and cutting mobile phone films, you first need to determine the model and screen size of the mobile phone to ensure that the cut film can perfectly fit the mobile phone screen. Then, according to the edge design of the mobile phone or the user's requirements, draw the lines or shapes that need to be cut on the film. Then, use the cutting equipment to accurately cut along these lines to remove the excess film material, and finally get a mobile phone film that meets the requirements.

[0003] A Chinese patent with application publication number: CN116038157A discloses a mobile phone film cutting and marking mechanism, the core components of which include a horizontal plate, symmetrical mounting holes A are provided at both ends of the horizontal plate for fixing, and a sliding hole and a through hole connected thereto are provided in the middle. Above the sliding hole, a slider is provided, and a connecting plate is connected to the bottom of the slider, which is then connected to the laser to realize the laser marking function. An electric push rod is installed on one side of the horizontal plate, and its output end is connected to the connecting plate through the through hole through the connecting block, driving the slider and the laser to move along the sliding hole to achieve precise marking. In view of the dust problem generated during the cutting process, the present invention also designs a unique dust cleaning mechanism. When cleaning is required, the collection bag is placed under the specially designed dust filter tube, and then the dust filter tube is pulled out from the inside of the sleeve. This action causes the filter screen plate hinged at the bottom of the dust filter tube to tilt, thereby smoothly discharging the accumulated dust into the collection bag. This cleaning process is efficient and convenient, and importantly, during the entire cleaning operation, the marking mechanism and the negative pressure dust suction mechanism can maintain normal operation to ensure production continuity and efficiency. However, the degree of automation in the existing technology is far from enough. Since the positioning of the mobile phone film needs to be extremely precise, positioning is extremely important and has a great impact in the process of automated scoring and cutting. The initial positioning accuracy of the mobile phone film in the existing technology is not enough. Summary of the invention

[0004] In view of the above technical problems, the present invention discloses a mobile phone film cutting and marking mechanism, including a workbench, on which a displacement component, a marking component, and a positioning component are installed. The displacement component includes a fixed rod, which is movable on the workbench, and a mounting plate is fixedly installed on the fixed rod, and a rotating cylinder is rotatably installed on the mounting plate, and a connecting rod is fixedly installed at the lower end of the rotating cylinder, and a supporting cylinder is fixedly installed on the connecting rod, and a suction cup is installed at the lower end of the supporting cylinder. The positioning component includes a shift plate 1 and an extrusion rod 2, and the shift plate 1 and the extrusion rod 2 are fixedly installed on the workbench. Through the above technical solution, the suction cup absorbs the mobile phone film, driving the mobile phone film to contact the shift plate 1 and the extrusion rod 2. Since the initial position of the mobile phone film is not accurate, the fixed rod continues to move after the mobile phone film contacts the shift plate 1 and the extrusion rod 2, and compensation is performed by rotating the connecting rod.

[0005] Furthermore, a torsion spring is sleeved on the rotating cylinder, and the torsion spring is fixedly connected to the connecting rod and the mounting plate. Through the above technical solution, when the mounting plate returns to its original position and starts adsorption again, the connecting rod returns to its original position driven by the torsion spring.

[0006] Furthermore, the positioning assembly also includes an extrusion plate, which is slidably mounted on the first shift plate, a spring is fixedly mounted between the extrusion plate and the first shift plate, an extrusion block is fixedly mounted on the extrusion plate, and the lower end of the extrusion block is in contact with the workbench.

[0007] Furthermore, an extrusion rod 1 and a shift rod 2 are fixedly mounted on the extrusion block, and the extrusion rod 1 and the shift rod 2 are vertically arranged.

[0008] Furthermore, the lower sides of the squeezing block, squeezing rod 1 and shift rod 2 are all rounded. Through the above technical solution, the mobile phone film that reaches the specified position can be compressed, and the rounded corner setting can make the mobile phone film push the squeezing block, squeezing rod 1 and shift rod 2 open, and automatically compress the mobile phone film.

[0009] Furthermore, the marking assembly includes a mounting frame, a moving assembly is mounted on the mounting frame, a marking cylinder is mounted at the output end of the moving assembly, a laser is mounted on the lower side of the marking cylinder, and the laser performs marking and cutting.

[0010] Furthermore, a sealing plate is fixedly mounted on the lower side of the marking cylinder, and the sealing plate is used for sealing during cutting. Powder pipes are arranged on both sides of the marking cylinder, and a dust collecting box is arranged on the upper side of the marking cylinder to suck the cutting dust into the dust collecting box.

[0011] Furthermore, two dust exhaust pipes are fixedly mounted on the mounting frame, and dust exhaust heads are fixedly mounted on the dust exhaust pipes. The dust exhaust heads are inserted into the dust collecting box to discharge the dust in the dust collecting box. Through the above technical solution, the sealing plate can seal the cutting position to prevent dust from flying around. At the same time, the dust is adsorbed into the dust collecting box through the powder pipe, and then moves to the designated position and flows out from the dust exhaust pipe.

[0012] The beneficial effects of the present invention compared with the prior art are:

[0013] (1) Through the technical solution of the present invention, the suction cup absorbs the mobile phone film, driving the mobile phone film to contact the shift plate 1 and the squeezing rod 2. Since the initial position of the mobile phone film is not accurate, the fixed rod continues to move after the mobile phone film contacts the shift plate 1 and the squeezing rod 2, and compensation is performed by rotating the connecting rod.

[0014] (2) Through the technical solution of the present invention, when the mounting plate returns to its original position and starts adsorption again, the connecting rod returns to its original position driven by the torsion spring.

[0015] (3) Through the technical solution of the present invention, the mobile phone film that reaches the specified position can be compressed, and the rounded corner setting can enable the mobile phone film to push open the squeezing block, squeezing rod one and shift rod two, and automatically compress the mobile phone film.

When the mounting plate 102 returns to its original position and starts to adsorb again, the connecting rod 104 returns to its original position driven by the torsion spring 103.

[0028] In this embodiment, the positioning assembly 3 includes a first shift plate 301 and a second extrusion rod 307 , and the first shift plate 301 and the second extrusion rod 307 are fixedly mounted on the workbench 4 . Through the above technical solution, the suction cup 107 absorbs the mobile phone film, driving the mobile phone film to contact the shift plate 1 301 and the squeezing rod 2 307. Since the initial position of the mobile phone film is not accurate, the fixed rod 101 continues to move after the mobile phone film contacts the shift plate 1 301 and the squeezing rod 2 307, and compensation is performed by rotating the connecting rod 104.

The laser 212 performs marking and cutting. A sealing plate 213 is fixedly installed on the lower side of the marking cylinder 211. The sealing plate 213 performs sealing during cutting. Powder pipes 214 are arranged on both sides of the marking cylinder 211. A dust box 216 is arranged on the upper side of the marking cylinder 211 to suck the cutting dust into the dust box 216. Two dust exhaust pipes 217 are fixedly installed on the mounting frame 205. A dust exhaust head 218 is fixedly installed on the dust exhaust pipe 217. The dust exhaust head 218 is inserted into the dust box 216 to release the dust in the dust box 216. Through the above technical solution, the sealing plate 213 can close the cutting position to prevent dust from flying around. At the same time, the dust is adsorbed into the dust box 216 through the powder pipe 214, and then moves to the designated position and flows out from the dust exhaust pipe 217. A waste tray 7 is provided at one side of the workbench 4 , and the dust is poured into the waste tray 7 .

[0030] In this embodiment, the moving component includes a motor 206 and a slide bar 215, and both are fixedly mounted on the mounting frame 205. A lead screw 207 is fixedly mounted on the rotating shaft of the motor 206, and a moving plate 208 is slidably mounted on the slide bar 215. The moving plate 208 moves in cooperation with the lead screw 207. A motor 3 209 is fixedly mounted on the moving plate 208, and a lead screw 210 is fixedly mounted on the rotating shaft of the motor 3 209. A marking cylinder 211 is slidably mounted on the moving plate 208, and the marking cylinder 211 is moved by the lead screw 210.

[0031] Working principle: the mobile phone film is sent to the workbench 4 through a conveying device. The conveying device can be a transmission belt or can be placed manually. In this embodiment, a conveyor belt is used, and the mobile phone film is limited by a baffle 5 to prevent the position deviation of the mobile phone film from being too large, which causes the displacement component 1 to be unable to grab. When it is transported to the workbench 4, the moving motor 8 is started, and the moving motor 8 drives the fixed rod 101 to move through the moving screw 9. The fixed rod 101 drives the mounting plate 102 to move, so that the torsion spring 103 reaches the upper side of the mobile phone film, and then the air pump 109 is started. The air pump 109 finally absorbs the mobile phone film through the suction cup 107. The height of the suction cup 107 is slightly higher than the mobile phone film, so it can be sucked up without moving up and down. In the natural state, the connecting rod 104 is driven by the torsion spring 103 to be far away from the positioning component 3, that is, it is aligned with the shift plate 3. 01 and the squeezing rod 2 307 are both at forty-five degrees, and then the displacement component 1 is moved in the opposite direction, driving the mobile phone film to move toward the positioning component 3. The mobile phone film first contacts the lower end of the shift rod 2 306 and lifts the shift rod 2 306 through the rounded corners. Finally, the mobile phone film contacts the shift plate 1 301, and then the displacement component 1 continues to move. At this time, the mobile phone film cannot continue to follow, so the connecting rod 104 is driven to rotate by the supporting tube 106. During the rotation process, it gradually contacts the squeezing rod 2 307, and finally the mobile phone film is fixed to the squeezing block 304, the squeezing rod 1 305 and the lower side of the shift rod 2 306 through the pressure of the spring 302. Through the adjustment of the connecting rod 104, the displacement component 1 does not have to be moved to be accurate, and the initial position of the mobile phone film on the workbench 4 does not have to be accurate. In the end, they can all contact the shift plate 1 301 and the squeezing rod 2 307 for accurate positioning.

[0032] Then, motor 206 and motor 3 209 are started to drive the scribing cylinder 211 to move, and then the scribing and cutting are performed by the laser 212. During the cutting process, the sealing plate 213 is always in contact with the upper side of the mobile phone film. During the cutting process, the dust is directly sucked away and enters the dust box 216 through the powder tube 214. After the cutting is completed, if the dust in the dust box 216 needs to be poured out, the dust box 216 is moved to contact with the dust exhaust pipe 217, and the dust exhaust head 218 is inserted into the dust box 216. A one-way valve can be set on the dust box 216. Only when the dust exhaust head 218 is inserted can it be poured out. After insertion, start motor 1 201 to drive the mounting frame 205 to flip. At this time, the dust box 216 and the dust exhaust pipe 217 are in a vertical state, and the dust falls and lands in the waste tray 7.

[0033] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
