[0013] Preferably, the length of the second mounting plate is greater than that of the first mounting plate, and the regulating assembly includes a pull rope and a limit rod. The limit rod is a T-shaped rod, and the horizontal end of the pull rope is fixedly connected to the inside of the rotating frame, and the other end faces the second mounting plate. One end of the pull rope passes through the first mounting plate and is fixedly connected to the bottom of the sealing block, and the other end is fixedly connected to the bottom side of the end of the second mounting plate. The limit rod is used to limit the position of the pull rope.

[0014] Preferably, a buffer component is provided inside the fixing tube, and the buffer component is used to alleviate the impact force generated when the display screen is placed.

[0015] Preferably, the buffer assembly includes an elastic air tube, an extrusion tube and a contact plate, the elastic air tube is fixedly mounted on the first mounting plate and is located inside the support tube, a sliding opening is opened in the middle of the sealing block, the extrusion tube is fixedly connected to the upper end of the elastic air tube, and the sealing sliding is arranged inside the sliding opening, and the contact plate is fixedly connected to the upper end of the extrusion tube.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By making the screen surface of the display screen contact with multiple fixing components, four suction cups are adsorbed and connected with the four corners of the display screen, so that the display screen does not contact the conveyor belt, and the wear of the display screen by impurities on the conveyor belt is avoided. The present invention can ensure the effective fixation of the display screen during the transmission process, and reduce the wear of the display screen;

[0022] 2. By changing the position of the bottom plate and the rotating frame inside the installation port, the width of the transmission space can be changed, so that the transmission space can be adjusted to a suitable size according to the size of the display screen. At the same time, the installation and disassembly of the installation components can be completed quickly, so that the conveyor belt can still transport different components;

[0023] 3. As the weight of the display screen acts on the fixed component, the second mounting plate that moves upward will pull one end of the pull rope and the other end of the pull rope downward, so that the piston slides down inside the fixed tube, sucking the gas inside the suction cup to create negative pressure, and adsorbing the suction cup on the surface of the display screen. The placement of the display screen is used to automatically control the pulling effect of the regulating component on the piston, reducing the setting of electronic components and ensuring the normal regulation of the piston.

[0024] 4. The display screen is first contacted by the elastic extrusion tube and the contact plate. When the gravity of the display screen acts on the contact plate, the extrusion tube squeezes the elastic air tube. At this time, the gas inside the elastic air tube is discharged to reduce the impact force generated when the display screen is placed. Then the extrusion tube is squeezed into the fixed tube, and the display screen contacts the suction cup again. The contact plate and the suction cup buffer the impact force twice, thus avoiding the display screen from being damaged by impact during placement and protecting the placement of the display screen.

[0025] 5. After the extrusion tube squeezes and exhausts the elastic air tube, the gas will be discharged from the gas outlet groove on the side of the contact plate. The extruded gas has a certain impact force, so the position on the display screen that is about to be adsorbed by the suction cup is jetted to clean, thereby ensuring the cleanliness of the adsorption position and the effective adsorption of the suction cup and the display screen;

[0026] 6. The clamping airbag installed on the second mounting plate can effectively elastically clamp and limit the side of the display screen, thereby preventing the display screen from shifting during the tilt transmission process, and playing a role in fixing and protecting the display screen.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0040] Reference Figure 1-Figure 10 A transmission device used in display screen production, comprising: a lifting platform 1 and a conveyor belt 2 installed inside the lifting platform 1, wherein a plurality of mounting ports 9 are provided on the conveyor belt 2, four of the mounting ports 9 form a group, and mounting components 3 are provided inside the mounting ports 9, and the four mounting components 3 are respectively fixed inside the four mounting ports 9 of a group, and a transmission space is formed in the middle;

[0041] The mounting assembly 3 includes a rotating frame 31, a rotating shaft 32, a first mounting plate 33 and a second mounting plate 34. The rotating shaft 32 is rotatably mounted inside the rotating frame 31. The first mounting plate 33 is fixedly connected to one side of the rotating shaft 32 close to the transmission space. The second mounting plate 34 is fixedly connected to the other side of the rotating shaft 32. The first mounting plate 33, the second mounting plate 34 and the rotating shaft 32 form a check-shaped seesaw.

[0042] The mounting assembly 3 is provided with a fixing assembly 4, and the fixing assembly 4 includes an elastic tube 41, a fixing tube 42, a suction cup 43 and a piston member 44. The elastic tube 41 is fixedly connected to the upper surface of the first mounting plate 33, the fixing tube 42 is fixedly connected to the upper end of the elastic tube 41, the suction cup 43 is fixedly connected to the upper end of the fixing tube 42, and the piston member 44 is arranged inside the fixing tube 42;

[0043] A regulating component 5 is disposed at the bottom of the piston member 44 , and the regulating component 5 is used to drive the piston member 44 to slide up and down in a sealed manner inside the fixed tube 42 .

[0044] In the embodiment of the application of the above technical solution, a transmission space is formed on the conveyor belt 2 by four installation components 3, thereby ensuring the relative independence of the display screens during the transmission process and avoiding collision of the display screens during the transmission process.

[0045] By bringing the screen surface of the display screen into contact with a plurality of fixing components 4, four suction cups 43 are adsorbed and connected to the four corners of the display screen, so that the display screen is not in contact with the conveyor belt 2, thereby avoiding the wear of the display screen by impurities on the conveyor belt 2. At the same time, the position of the piston 44 is adjusted by the adjustment component 5, thereby ensuring the adsorption between the suction cup 43 and the display screen.

[0046] The hook-shaped seesaw formed by the first mounting plate 33 and the second mounting plate 34 can provide a buffer during the placement of the display screen through the rotating shaft 32 with torsion in the middle. At the same time, the hook-shaped seesaw has sufficient deformation space to protect the display screen.

[0047] The present invention can ensure the effective fixation of the display screen during the transmission process and reduce the wear on the display screen.

[0048] The preferred technical solution in this embodiment is:

[0049] Reference Figure 4-6 The mounting assembly 3 also includes a base plate 35 and two fixing bolts 36. The rotating frame 31 and the base plate 35 are respectively provided with the upper and lower sides of the conveyor belt 2. The two fixing bolts 36 pass through the mounting opening 9 and are fixedly connected between the rotating frame 31 and the base plate 35 to fix the position of the rotating frame 31 on the conveyor belt 2.

[0050] When the display screen is transmitted, since the sizes of display screens of different specifications are different, in order to effectively adsorb and fix the display screen, the width of the transmission space is changed by changing the position of the bottom plate 35 and the rotating frame 31 inside the installation port 9, so that the transmission space can be adjusted to a suitable size according to the size of the display screen. The bottom plate 35 and the fixing bolt 36 are both made of elastic material, thereby ensuring the normal rotation of the conveyor belt 2. At the same time, through the connection between the bottom plate 35 and the rotating frame 31, the installation and disassembly of the installation component 3 can be quickly completed, so that the conveyor belt 2 can still transmit different components.

[0051] Reference Figure 7-8 The piston member 44 includes a sealing block 441 and a support tube 442. The support tube 442 is fixedly mounted on the first mounting plate 33 and is located inside the fixed tube 42. The sealing block 441 is fixedly connected to the upper end of the support tube 442 and is sealingly slidably arranged inside the fixed tube 42.

[0052] A spring is arranged inside the support tube 442 to elastically support the sealing block 441. A sealing strip is arranged on the side of the sealing block 441 to ensure the sealed sliding of the sealing block 441 inside the fixing tube 42, thereby realizing the suction of the gas inside the suction cup 43 and ensuring that the suction cup 43 is adsorbed and fixed to the display screen.

[0053] Reference Figure 4-6 The length of the second mounting plate 34 is greater than that of the first mounting plate 33. The regulating component 5 includes a pull rope 51 and a limit rod 52. The limit rod 52 is a T-shaped rod, and the horizontal end is fixedly connected to the inside of the rotating frame 31, and the other end faces the second mounting plate 34. One end of the pull rope 51 passes through the first mounting plate 33 and is fixedly connected to the bottom of the sealing block 441, and the other end is fixedly connected to the bottom side of the end of the second mounting plate 34. The limit rod 52 is used to limit the position of the pull rope 51.

[0054] Since the length of the second mounting plate 34 is greater than that of the first mounting plate 33, when the end of the first mounting plate 33 moves downward, the upward tilting distance of the end of the second mounting plate 34 will be greater than the downward moving distance of the first mounting plate 33. The limit rod 52 is used to limit the deformation of the pull rope 51 to prevent the pull rope 51 from having a large angle change, so that the pull rope 51 can be pulled to complete the downward pulling of the piston member 44.

[0055] During the placement of the display screen, the weight of the display screen acts on the fixing assembly 4, causing the first mounting plate 33 to move downward. The downwardly moved first mounting plate 33 will drive the second mounting plate 34 to tilt upward through the rotating shaft 32. The upwardly moved second mounting plate 34 will pull one end of the pull rope 51 and will pull the other end of the pull rope 51 downward, thereby causing the piston 44 to slide down inside the fixing tube 42, sucking the gas inside the suction cup 43, creating negative pressure, and adsorbing the suction cup 43 to the surface of the display screen.

[0056] The placement of the display screen is used to automatically control the pulling action of the regulating component 5 on the piston 44 , thereby reducing the number of electronic components and ensuring normal regulation of the piston 44 .

[0057] Reference Figure 7-8 A buffer component 6 is disposed inside the fixing tube 42, and the buffer component 6 is used to alleviate the impact force generated when the display screen is placed;

[0058] The buffer assembly 6 includes an elastic air tube 61, an extrusion tube 62 and a contact plate 63. The elastic air tube 61 is fixedly mounted on the first mounting plate 33 and is located inside the support tube 442. A sliding opening is provided in the middle of the sealing block 441. The extrusion tube 62 is fixedly connected to the upper end of the elastic air tube 61, and the sealing sliding is arranged inside the sliding opening. The contact plate 63 is fixedly connected to the upper end of the extrusion tube 62.

[0059] An air outlet is provided in the middle of the contact plate 63 and is connected to the elastic air pipe 61 through the extrusion tube 62. The contact plate 63 is in the shape of an inverted truncated cone and has a plurality of air outlet grooves provided on the side of the upper end.

[0060] Since a large impact force will be generated during the placement of the display screen, if it is placed in the middle, the impact force may cause damage to the display screen, affecting the normal use of the display screen. The volume of the contact plate 63 and the suction cup 43 can be selected independently to ensure contact with the display screen;

[0061] The display screen is first contacted by the elastic extrusion tube 62 and the contact plate 63. When the gravity of the display screen acts on the contact plate 63, the extrusion tube 62 squeezes the elastic air tube 61. At this time, the impact force generated when the display screen is placed can be reduced by the discharge of the gas inside the elastic air tube 61. Then the extrusion tube 62 is squeezed into the fixing tube 42, and the display screen is contacted with the suction cup 43 again. The contact plate 63 and the suction cup 43 are used for two times to buffer the impact force, thereby avoiding the display screen from being damaged by impact during the placement process, and protecting the placement of the display screen.

[0062] At the same time, since dust and impurities may adhere to the display screen, these impurities may affect the contact effect between the suction cup 43 and the display screen during the contact process with the suction cup 43, resulting in the suction cup 43 being unable to effectively adsorb the display screen;

[0063] After the extrusion tube 62 squeezes and exhausts the elastic air tube 61, the discharged gas will be discharged from the air outlet groove on the side of the contact plate 63. The extruded gas has a certain impact force, thereby jetting and cleaning the position on the display screen that is about to be adsorbed by the suction cup 43, thereby ensuring the cleanliness of the adsorption position and ensuring the effective adsorption of the suction cup 43 and the display screen.

[0064] Reference Figure 9-10 Two second mounting plates 34 symmetrically arranged parallel to the central axis of the conveyor belt 2 are fixedly connected with a clamping airbag 7, the clamping airbag 7 is made of elastic material, and a plurality of arc-shaped protrusions for clamping the display screen are arranged on the side away from the second mounting plate.

[0065] During the transmission of the display screen, the transmission angle of the conveyor belt 2 is adjusted by the lifting platform 1, which causes the display screen to be tilted and transferred on the conveyor belt 2. The existing transmission belt cannot effectively fix the position of the display screen, which easily causes wear of the display screen.

[0066] When the display screen squeezes the fixing assembly 4, the first mounting plate 33 will move downward under the action of gravity. The downward movement of the first mounting plate 33 will drive the second mounting plate 34 to deflect upward. The clamping airbag 7 installed on the second mounting plate 34 can effectively elastically clamp and limit the side of the display screen, thereby preventing the display screen from shifting during the tilt transmission process, and playing a role in fixing and protecting the display screen.

[0067] Reference Fig. 9 A magnetic component 8 is provided between the lifting platform 1 and the first mounting plate 33, and the magnetic component 8 is used to drive the first mounting plate 33 to move upward;

[0068] The magnetic assembly 8 includes a frame plate 81, two first magnetic blocks 82 and multiple second magnetic blocks 83. The frame plate 81 is fixedly installed at the discharge end of the lifting platform 1. The two first magnetic blocks 82 are symmetrically fixedly connected to the upper side of the frame plate 81, and the distance between the two first magnetic blocks 82 is consistent with the distance between the two mounting ports 9. The multiple second magnetic blocks 83 are respectively fixedly connected under the multiple first mounting plates 33, and the magnetic poles of the first magnetic block 82 and the second magnetic block 83 on the side close to each other are the same.

[0069] When the display screen needs to be removed from the conveying device, the suction cup 43 adsorbs and fixes the display screen, which easily affects the normal transfer of the display screen. It is necessary to release the adsorption between the suction cup 43 and the display screen when the display screen is unloaded.

[0070] When the display screen moves to the discharge end, since the magnetic poles of the first magnetic block 82 and the second magnetic block 83 are the same on one side close to each other, the second magnetic block 83 will generate a repulsive force when it approaches the first magnetic block 82. Since the position of the second magnetic block 83 is fixed, only the first magnetic block 82 can be displaced, which will cause the first magnetic block 82 to move upward due to the repulsive force, thereby moving the first mounting plate 33 upward and the second mounting plate 34 downward. The pulling effect of the pull rope 51 on the piston member 44 disappears, and the sealing block 441 moves upward under the action of the elastic support tube 442, thereby unlocking the adsorption effect between the suction cup 43 and the display screen, facilitating the transfer of the display screen.

[0071] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
