Description

Technical Field

[0001] The utility model relates to the technical field of display screen transportation, in particular to a protective film transportation mechanism for preventing the protective film from being adsorbed onto the display screen. Background Art

[0002] With the rapid development of electronic display technology, the quality and display effects of screens, whether smartphones, tablets, or laptops, have become an increasing focus of consumer attention. However, protecting these delicate and fragile display screens from scratches and contamination during production, assembly, and transportation is a challenge. Therefore, during transportation, the display screens are covered with a protective film to protect them from scratches and abrasions, effectively ensuring the safe transportation of the display screens.

[0003] Before the display screen is produced, the protective film on the display screen needs to be removed and then the display screen is transferred to the production line. In order to ensure the transfer efficiency of the display screen, the current production line will use a suction cup specially used to adsorb the display screen to transfer the display screen to the production line. However, since the protective film will adhere to the surface of the display screen, the user needs to remove the protective film first. If the protective film is removed manually, the display screen may be easily offset, resulting in the suction between the suction cup and the display screen being unable to ensure stable adsorption, and the display screen may easily fall off. If the protective film is sucked away first by the suction cup, the protective film and the display screen will be adsorbed together, making it impossible to transfer the display screen to the production line. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the problem that the protective film and the display screen are adsorbed together when the suction cup adsorbs the protective film.

[0024] 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.

[0025] See also Figure 1-3A protective film transport mechanism that avoids adsorption to a display screen includes a connecting plate 1. A display screen adsorption mechanism and a protective film adsorption mechanism are provided on the connecting plate 1. The suction force of the protective film adsorption mechanism is smaller than that of the display screen adsorption mechanism. The adsorption structure can adsorb the protective film without adsorbing it to the display screen, so that the protective film will not affect the transport of the display screen, and can also avoid the situation where the display screen is adsorbed when the protective film is adsorbed and removed.

[0026] As a further solution of the present invention, the protective film adsorption mechanism includes: a plurality of protective film suction cups 105 provided at the bottom of the connecting plate 1, and the display screen adsorption mechanism includes: a plurality of display screen suction cups 109 provided at the bottom of the connecting plate 1, the protective film suction cups 105 and the display screen suction cups 109 are located on the same side of the connecting plate 1, and the distance between the protective film adsorption cups 105 and the connecting plate 1 is greater than the distance between the display screen adsorption cups 109 and the connecting plate 1

[0027] The protective film adsorption mechanism includes: an adsorption tube 101 provided on the top of the protective film suction cup 105 and connected to the protective film suction cup 105, a paper suction vacuum valve 102 is provided on the top of the connecting plate 1, and a plurality of transmission pipes 103 are provided on the surface of the paper suction vacuum valve 102. A suction pipe 104 is provided on the surface of the adsorption tube 101, and the plurality of transmission pipes 103 are respectively connected to the suction pipe 104. When the protective film on the display screen is to be adsorbed, the paper suction vacuum valve 102 can be started. After the paper suction vacuum valve 102 is started, the bottom end of the adsorption tube 101 will become a negative pressure area through the conduction between the transmission pipe 202 and the suction pipe 203, so that the protective film on the display screen can be adsorbed. At the same time, because the length of the adsorption tube 101 is longer than that of the suction pipe 106, the adsorption tube 101 will first contact the protective film, and the suction force of the adsorption tube 101 alone cannot adsorb to the display screen, so that the purpose of only adsorbing the protective film can be achieved.

[0028] In some embodiments, the top of the connecting plate 1 is provided with a plurality of mounting plates a3 that cooperate with the first adsorption tube 11, and a fixing plate 302 is provided on one side of the mounting plate a3. A locking plate 303 that cooperates with the fixing plate 302 is provided on one side of the first adsorption tube 11. The fixing plate 302 and the locking plate 303 are fixed by screws. When the first adsorption tube 11 is to be disassembled, the screws between the fixing plate 302 and the locking plate 303 can be released to release the connection between the fixing plate 302 and the locking plate 303, so that the locking plate 303 can be disassembled, thereby enabling the first adsorption tube 11 to be disassembled. Remove the first adsorption tube 11. The adsorption tube 101 mainly converts positive pressure into negative pressure to adsorb film materials through the air. The first adsorption tube 11 adsorbs the protective film by making the air pressure inside the tube greater than the air pressure outside the tube. At this time, the first adsorption tube 11 is close to the protective film, so that the air pressure between the first adsorption tube 11 and the protective film is reduced, so that the pressure difference between the upper and lower parts of the protective film can make the protective film suspended in the air, thereby ensuring that the first adsorption tube 11 can adsorb the protective film on the display screen through the air. Compared with conventional negative pressure adsorption that requires contact with the material, this method is convenient for adsorbing film materials through the air.

[0029] In some embodiments, multiple mounting plates b301 are provided on the tops of multiple connecting plates 1 for cooperating with the second adsorption tube 12. The top ends of the second adsorption tubes 12 pass through the mounting plates b301. The surfaces of the second adsorption tubes 12 are provided with threads. Multiple nuts 105 are installed on the surfaces of the second adsorption tubes 12 through threads. To adjust the length of the second adsorption tubes 12 at the bottom of the connecting plate 1, the nuts 105 can be rotated in the opposite direction. After the nuts 105 are rotated, they will begin to move away from the connecting plate 1 due to the threaded engagement with the second adsorption tubes 12. After the nuts 105 move, the distance between the nuts 105 will increase, thereby releasing the fixation of the second adsorption tubes 12 and allowing the second adsorption tubes 12 to start moving up and down, thereby achieving the purpose of adjusting the second adsorption tubes 12. After adjusting the second adsorption tubes 12, the nuts 105 are rotated forward. After the nuts 105 rotate, they will start to move toward the connecting plate 1. When the nuts 105 contact the connecting plate 1, the nuts 105 are continued to be rotated to lock the nuts 105, thereby fixing the second adsorption tubes 12.

[0030] In some embodiments, a connecting groove is provided on the top of the mounting plate a3 and the mounting plate b301, and a connecting groove 304 is provided on the top of the mounting plate a3 and the mounting plate b301. A fastener 305 is provided inside the connecting groove 304 for penetrating the connecting groove 304 to lock the mounting plate a3 and the mounting plate b301. The fastener 305 is a screw and a nut. At the same time, the fastener 305 can be a standard bolt, pin, etc. that can be purchased on the market. When it is necessary to adjust the protruding distance of the mounting plate a3 and the mounting plate b301 on the connecting plate 1, the fixing of the mounting plate a3 and the mounting plate b301 can be released by removing the fastener 305. At this time, the mounting plate a3 and the mounting plate b301 can be moved to adjust the protruding distance of the mounting plate a3 and the mounting plate b301 on the connecting plate 1. After the adjustment is completed, the fastener 305 is installed through the connecting groove 304 so that the fastener 305 can fix the mounting plate a3 and the mounting plate b301 through the cooperation with the connecting groove 304.

[0031] In some embodiments, the display screen adsorption mechanism includes: a transport suction pipe 107 provided at the top of the display screen adsorption plate 109 and connected to the display screen adsorption plate 109, a transport vacuum valve 108 provided at the top of the connecting plate 1, the vacuuming rate of the transport vacuum valve 108 is greater than the vacuuming rate of the paper suction vacuum valve 102, the top end of the transport suction pipe 107 passes through the connecting plate 1 and protrudes from the top of the connecting plate 1, the connecting plate 1 and the transport suction pipe 107 are installed and connected by bolts, and the transport vacuum valve 108 is connected to the transport suction pipe 107 through a connecting pipe. When the display screen is to be transported, the transport vacuum valve 108 can be started. After the transport vacuum valve 108 is started, the pipe mouth of the transport suction pipe 107 will become a vacuum area through the connecting pipe. Because the display screen adsorption plate 109 and the transport suction pipe 107 are connected, when the transport suction pipe 107 is evacuated, the bottom of the display screen adsorption plate 109 will become a vacuum area, so that the display screen can be adsorbed, thereby transporting the display screen.

[0032] In some embodiments, multiple connecting frames 2 are installed on the top of the connecting plate 1, and support columns 201 are arranged between the connecting frames 2. The two ends of the support columns 201 are respectively connected to the connecting frames 2. A reinforcing rib 202 is installed on one side of the connecting frame 2 by bolts. The support columns 201 can support the connecting frames 2. After the reinforcing rib 202 is installed on the connecting frame 2, the strength of the connecting frame 2 is enhanced. When the reinforcing rib 202 needs to be removed, the reinforcing rib 202 can be removed by removing the bolts. When the reinforcing rib 202 needs to be installed, the reinforcing rib 202 is installed by bolts.
