[0002] Before the computer external liquid crystal display is packed and shipped, flexible cushion packaging must be used to prevent screen breakage, corner damage and other problems caused by impact, falling or vibration during transportation. One of the commonly used methods is to fit foam supports with openings on both ends of the display screen. The foam supports can precisely fit the edges of the screen body, absorb impact force through the elasticity of the material, and ensure stable positioning of the screen body in the packaging box, effectively improving transportation safety and product integrity.

[0003] In the prior art, the work of fitting foam supports on both ends of the display screen is mostly performed manually. Manual operation of foam supports one by one limits the packaging rhythm and makes it difficult to meet the needs of high-speed assembly line operation. When the foam supports are large and numerous, long-term repeated handling and positioning significantly increases worker fatigue. SUMMARY

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention symmetrically arranges a cache frame on the top of the workbench for stacking and caching multiple foam bases. A conveyor belt is arranged on the other side of the workbench to transport the display screen to the packaging position of the workbench, and a foam seat transfer assembly is arranged between the conveyor belt and the cache frame.

A clamping cylinder 20 is fixedly provided on the side of the intermediate plate 16, and a clamping block 201 is fixedly provided at the output end of the clamping cylinder 20.

[0035] A foam seat opening identification and diversion component is provided at the top of the side of the vertical plate 14. The foam seat opening identification and diversion component transfers the opening toward the correct foam seat to the conveyor belt 41. A recovery port 5 is provided between the buffer frame 7 and the conveyor belt 41 on the workbench 2. A guide bucket 6 is provided at the bottom of the recovery port 5 to guide the foam seat passing through the recovery port 5 to the desired position to facilitate the recovery of the foam seat.

[0036] The foam seat with the wrong opening is discharged from the recovery port 5. The workbench 2 is provided with a self-avoidance component between the two buffer frames 7. When the foam seat opening identification and diversion component moves to the packaging station, the self-avoidance component drives the foam seat opening identification and diversion component to automatically move upward to avoid blocking the display screen from installing the foam seat at the packaging station.

[0037] The foam seat opening identification diversion assembly includes a central box 19, a connecting hose 18, and a fixed plate 17. Edge plates 30 are fixedly provided at both ends of the central box 19. One end of the edge plate 30 is movably inserted into the receiving column 25. A driving plate 28 is fixedly provided at one end of the receiving column 25. The outer wall of the receiving column 25 is fixedly connected to one end of the retaining spring 27. The other end of the retaining spring 27 is fixedly connected to the side of the edge plate 30. The receiving column 25 is fixedly provided with an adjustment shoulder 26 on one side of the outer wall of the edge plate 30. A central partition 29 is fixedly provided in the middle position of the inner cavity of the central box 19. The central partition 29 divides the inner cavity of the central box 19 into two independent air chambers.

[0038] A fixed plate 17 is fixedly provided in the middle position of the side of the side transverse groove 122, and the fixed plate 17 is fixedly connected to one end of the connecting hose 18, and the other end of the connecting hose 18 is fixedly connected to the middle position of the top of the center box 19. The side of the center box 19 is symmetrically fixedly connected with an air supply pipe 23, and a solenoid valve 231 is provided on the top of the air supply pipe 23. An air control micro switch 10 is fixedly provided at the bottom of the center plate 9, and a trigger block 151 is fixedly provided on the top of the common plate 15 on one side of the vertical rod 24.

[0039] The self-avoidance component includes a vertical rod 24 and a center plate 9. The center plate 9 is fixedly arranged on the top of the workbench 2. The top of the center plate 9 is sequentially provided with a bottom transverse surface 91, a lifting inclined surface 92 and a top transverse surface 93. A vertical rod 24 is fixedly arranged at the middle position on the top of the center box 19. The vertical rod 24 extends from the top of the common plate 15. An avoidance cross column 241 is screwed into the top of the side of the vertical rod 24. The avoidance cross column 241 is overlapped at the top of the bottom transverse surface 91 or the top of the lifting inclined surface 92 or the top transverse surface 93.

[0040] Horizontal plates 13 are fixedly provided at both ends of the common plate 15, and the other end of the horizontal plate 13 is fixedly connected to the side of the vertical plate 14. The vertical plate 14 is provided with an auxiliary blocking component in the vertical direction. The auxiliary blocking component prevents the foam seat from shifting when the foam seat opening identifies the diversion component for foam seat sorting.

[0041] The auxiliary blocking assembly includes an auxiliary baffle 21, an extension cross bar 22, and a lifting column 221. The auxiliary baffle 21 is movably inserted into the horizontal plate 13 in the vertical direction. An extension cross bar 22 is fixedly provided on the top of the auxiliary baffle 21. A lifting column 221 is fixedly provided on the other end of the extension cross bar 22. The lifting column 221 is overlapped on the top of the bottom horizontal surface 91 or the top of the lifting inclined surface 92 or the top of the top horizontal surface 93.

[0042] It should be added that when workers stack foam seats inside the cache frame 7, the openings of the multiple foam seats inside the two transfer frames 12 are all in a horizontal state and are all facing the two ends of the center box 19, and the adjustment shoulder 26 needs to be properly fixed to the outer wall of the receiving column 25. At this time, the spring 27 is kept with a certain pre-compression length. When air is blown into the center box 19 through the air supply pipe 23, the air can only push the receiving column 25 out through the drive plate 28 after the air pressure is higher than a certain value. The position of the air control microswitch 10 is set appropriately, and the trigger arm of the air control microswitch 10 is set long enough so that when the trigger block 151 moves along the bottom of the air control microswitch 10, the solenoid valve 231 will remain open for a period of time.

[0043] The specific implementation steps and principles of the present invention are as follows: The entire process starts with the transfer frame 12 being at the bottom of the buffer frame 7. The two transfer frames 12 obtain the foam seat from the buffer frame 7. At this time, the avoidance horizontal column 241 and the lifting column 221 are both at the top end of the bottom horizontal surface 91. At this time, one end of the auxiliary baffle 21 is at a side of the transfer frame 12, and the center box 19 is between the two transfer frames 12. The conveyor belt 41 drives the display screen to be packaged to move to the bottom of the center plate 9.

[0044] Start the transfer cylinder 1, the transfer cylinder 1 retracts, and the two transfer frames 12 drive the two foam seats to gradually move to the recovery port 5. During this period, the trigger block 151 presses the air control micro switch 10, and the solenoid valve 231 of the air supply pipe 23 is opened, and air is blown into the center box 19. At this time, there are two conditions. In the first condition, the opening direction of the foam seat inside the transfer frame 12 is horizontal and faces the two ends of the center box 19. At this time, the opening direction of the foam seat is correct, and the end of the connecting hose 18 connected to the fixing plate 17 will be closed by the foam seat itself. When air is blown into the center box 19, the inside of the center box 19 The air pressure gradually increases, which will push the receiving column 25 at one end of the driving plate 28 to extend and extend into the opening on the side of the foam seat. At this time, the foam seat is lifted up and will not fall when passing the recovery port 5; in the second case, the opening of the foam seat inside the transfer frame 12 is facing the wrong direction, and the end of the connecting hose 18 connected to the fixed plate 17 is not blocked and is in an open state. At this time, even if air is blown into the center box 19, the center box 19 will "leak", and the receiving column 25 will not extend. At this time, when the foam seat with the opening facing the wrong direction passes the recovery port 5, it will automatically fall into the recovery port 5 because the bottom is not lifted.

[0045] When the foam seat with the opening facing the correct direction continues to move from the recovery port 5 to the position of the conveyor belt 41, the trigger block 151 no longer presses the air control microswitch 10, and the air supply pipe 23 stops supplying air. Since one end of the connecting hose 18 connected to the fixing plate 17 is in a non-ideal fit with the side wall of the foam seat, the center box 19 begins to leak air, and the receiving column 25 is driven to retract to the initial position by the retaining spring 27. At this time, the avoidance column 241 and the lifting column 221 gradually move from the bottom horizontal surface 91 and the lifting inclined surface 92 to the top of the top horizontal surface 93. All components on the center box 19 move up to a certain height, and the auxiliary baffle 21 will move up from one side of the foam seat opening. Finally, the clamping cylinder 20 is started, and the two clamping cylinders 20 drive the two foam seats close to the display screen to be packaged.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
