[0034] The spring one 447 is arranged between the piston plate one 443 and the end wall of the second hydraulic cavity 423, and the side of the piston plate one 443 close to the support plate 444 is provided with a limiting block 448;

[0035] The driving block one 2 and the driving block two 3 are both provided with a receiving cavity one 21 for sliding of the connecting column 42, and the outer end of the receiving cavity one 21 is fixedly provided with an inclined pushing block 22, which can push the pushing strip 445 to slide;

[0036] The connecting plate 43 is provided with an L-shaped receiving groove two 431, the receiving groove two 431 is provided with a third hydraulic cavity 432, a fourth hydraulic cavity 433 and a sliding cavity two 434 penetrating through the bottom end of the connecting plate 43 in sequence from top to bottom along the height direction of the connecting plate 43, and the bottom of the third hydraulic cavity 432 and the bottom of the fourth hydraulic cavity 433 are in communication;

[0037] The second top block mechanism 45 comprises a top block 451, a sliding rod 452, a piston plate two 453, a supporting rod 454 and a pushing block 455, the top block 451 is slidingly arranged in the receiving groove two 431, the sliding rod 452 is sealingly slidingly arranged in the third hydraulic cavity 432, the sliding rod 452 is fixedly connected with the top block 451, the piston plate two 453 is sealingly slidingly arranged in the fourth hydraulic cavity 433, the supporting rod 454 is fixedly arranged on the piston plate two 453, the pushing block 455 in a semi-spherical shape is fixedly arranged on the supporting rod 454, a plurality of top blocks 451 are slidingly arranged in close contact, and the output end of the plurality of top blocks 451 is wrapped with an elastic pad two 456;

[0038] The piston plate two 453 and the end wall of the fourth hydraulic cavity 433 are provided with a spring two 457, and the side of the piston plate two 453 close to the supporting rod 454 is fixedly provided with a limiting rod 458.

[0039] During implementation, the driving blocks 1 2 and 2 3 at the four ends of the bottom plate 1 are driven to slide by hydraulic pressure, and at the same time, the connecting assembly 4 will slide along with the sliding of the driving blocks 1 2 and 2 3, that is, the two sides of the L-shaped connecting column 42 will slide along the driving blocks 1 2 and 2 3 respectively. During this process, the connecting column 42 located in the accommodating cavity 1 21 will slide out of the accommodating cavity 1 21, and at the same time, the part of the first ejecting block mechanism 44 slidingly arranged on the connecting column 42 will also slide out of the accommodating cavity 1 21. When the first ejecting block mechanism 44 is in the accommodating cavity 1 21, the pushing bar 445 will be squeezed on the end wall of the accommodating cavity 1 21, so that the pushing bar 445 is located inside the sliding cavity 1 424. At this time, the piston plate 1 443 The first hydraulic chamber 423 is pushed by the push bar 445 and the support plate 444 to slide along the second hydraulic chamber 423. Since the second hydraulic chamber 423 is connected to the bottom of the first hydraulic chamber 422, the sliding of the piston plate 1 443 can draw the oil in the first hydraulic chamber 422 into the second hydraulic chamber 423, so that the slide plate 442 can slide into the first hydraulic chamber 422 and drive the push bar 441 to slide into the receiving groove 1 421. That is, the first ejecting block mechanism 44 will be completely retracted into the connecting column 42. When the push bar 445 is separated from the receiving chamber 1 21, the push bar 445 is no longer subjected to the squeezing force. Therefore, the piston plate 1 443 can slide along the second hydraulic chamber 422 and push out the push bar 445 under the action of the spring 1 447. When the oil in the second hydraulic chamber 423 is pressed into the first hydraulic chamber 422, the slide plate 442 slides out of the first hydraulic chamber 421 and pushes the top strip 441 and the elastic pad 1 446 to slide out of the accommodating groove 1 421. At the same time, the limit block 448 limits the sliding distance of the piston plate 1 443 to ensure that the sliding distance of the top strip 441 and the elastic pad 1 446 can just fill the gap left when the connecting column 42 is separated from the driving block 1 2 and the driving block 2 3, so that the connecting column 42 and the inner side surfaces of the driving block 1 2 and the driving block 2 3 form a continuous supporting surface. Similarly, during the sliding process of the connecting column 42, the connecting plate 43 will slide out of the accommodating chamber 2 11. Accordingly, the second The top block mechanism 45 will also shrink into the connecting plate 43, and the second top block mechanism 45 that is separated from the accommodating cavity 2 11 will slide out of the connecting plate 43, that is, multiple top blocks 451 and part of the elastic pad 2 456 can slide out of the accommodating groove 2 431, thereby filling the vacant position when the fixed plate 41 is separated from the bottom plate 1, that is, ensuring that the upper top surface of the fixed plate 41 and the bottom plate 1 can always form a continuous supporting plane when the fixed plate 41 slides, so that the bottom plate 1 and the fixed plate 41 will not have a broken surface when supporting the collection screen. At the same time, the side surface of the tray composed of the driving block 1 2, the driving block 2 3 and the connecting column 42 can also form a continuous supporting plane without a broken surface, so that the screen will not be damaged during transportation.Meanwhile, the fracture surface between the bottom plate 1 and the driving block one 2 and the driving block two 3 is filled by the chain plate mechanism 5, thereby forming a tray structure with variable size and continuous supporting surface, so that different models of mobile phone screens can be effectively transported without replacing the tray structure, thereby speeding up the detection efficiency of the mobile phone screen.

[0040] In the embodiment, the bottom plate 1 is provided with a receiving cavity two 11 for sliding of the connecting plate 43, and the outer end of the receiving cavity two 11 is fixedly provided with an inclined push strip 12, which can push the push block 455 to slide. Figure 7

[0041] It should be noted that during the process of retracting the connecting column 42 into the receiving cavity one 21 and retracting the connecting plate 43 into the receiving cavity two 11, the inclined push block 22 and the inclined push strip 12 both extend to the outside of the receiving cavity one 21 and the receiving cavity two 11, so that when the connecting column 42 slides into the receiving cavity one 21, the push strip 445 will first contact the inclined push block 22 and be pushed to slide, so that the top strip 441 is retracted into the receiving groove one 421, and then slides into the receiving cavity one 21. Similarly, the push block 455 will also first contact the inclined push strip 12, so that the top block 451 is retracted into the receiving groove two 431, and then slides into the receiving cavity two 11. In this way, it is prevented that the protruding top block 451 or the top strip 441 is stuck outside the receiving cavity two 12 or the receiving cavity one 21 during the retraction process, so as to avoid the situation that the tray structure cannot be retracted.

[0042] In the embodiment, the chain plate mechanism 5 is composed of a plurality of support plates 51 rotatably connected, one side of the support plate 51 is fixedly provided with an arc-shaped rotating block 52, the other side of the support plate 51 is provided with an arc-shaped rotating groove 53, and adjacent two support plates 51 are rotatably connected through the arc-shaped rotating block 52 and the arc-shaped rotating groove 53, and a plurality of support plates 51 are rotatably connected to form a flexible chain plate. Figure 2 Figure 8 The driving block one 2 and the driving block two 3 are both provided with a cavity 23, the length of the cavity 23 is the same as the length of the support plate 51, the upper and lower sides of the cavity 23 are respectively provided with a through hole 231, and two rotating rollers 232 are rotatably arranged in the cavity 23, one end of the flexible chain plate is fixedly connected with the bottom plate 1, and the other end penetrates into the cavity 23 from the through hole 231 above the cavity 23 and is wrapped on the two rotating rollers 232 and penetrates out from the through hole 231 below the cavity 23.

[0043]

[0044] ​​​The driving block one 2 and the driving block two 3 are fixedly provided with two T-shaped plates 24 at the positions of the two through holes 231, and the support plate 51 is provided with a T-shaped groove 511, and the T-shaped plate 24 is slidingly arranged along the T-shaped groove 511.

[0045] In the embodiment, the bottom plate 1 is provided with a plurality of pull wire discs 13, and the pull wire discs 13 are provided with pull ropes 14, and the other ends of the pull ropes 14 are fixedly connected with the flexible chain plates, and the pull wire discs 13 are provided with clockwork springs at the positions of the rotation connection with the bottom plate 1. Figure 7

[0046] When the driving block one 2 or the driving block two 3 is not separated from the bottom plate 1, the chain plate mechanism 5, i.e. the flexible chain plate, is pulled to slide into the bottom side of the bottom plate 1 under the action of the pull wire discs 13 and the pull ropes 14, and the other end of the flexible chain plate is also wrapped on the two rotating rollers 232 and connected with the bottom plate 1 through the through hole at the upper end of the cavity 23. When the driving block one 2 or the driving block two 3 is separated from the bottom plate 1, the bottom plate 1 pulls the flexible chain plate to slide out from the bottom side of the bottom plate 1, and the flexible chain plate is pulled to slide to the position between the bottom plate 1 and the driving block one 2 or the driving block two 3 through the transmission of the rotating roller 232, so as to fill the gap between the bottom plate 1 and the driving block one 2 or the driving block two 3. At this time, the flexible chain plate pulls the pull rope 14, and the pull wire disc 13 rotates and the clockwork spring is wound up. When the driving block one 2 or the driving block two 3 is reset and slides, the pull wire disc 13 rotates under the action of the clockwork spring, and the pull rope pulls the flexible chain plate on the upper part of the bottom plate 1 back to the bottom part of the bottom plate 1. When the flexible chain plate slides out of the two through holes 231, the T-shaped plate 24 fixedly arranged at the through hole slides into the T-shaped groove 511 on the support plate 51, so that the plurality of support plates 51 sliding out of the through hole 231 are always in the same plane under the action of the T-shaped plate 24, and the support plate 51 in the cavity 23 is not limited, i.e. the two support plates 51 can rotate, so that the flexible chain plate can rotate along the surface of the two rotating rollers 232, thereby realizing the alternation of the flexible chain plate from the upper and lower sides of the bottom plate 1, and the flexible chain plate can maintain good supporting stiffness and form a supporting plane to fill the gap between the bottom plate 1 and the driving block one 2 or the driving block two 3 after the alternation, thereby ensuring that the bottom surface and the side surface of the tray structure formed by the driving block one 2, the driving block two 3 and the connecting assembly 4 can always form a continuous supporting plane, thereby ensuring that the mobile phone screen can be safely and smoothly conveyed.

[0047] ​In summary, the present application provides a universal mobile phone screen conveying tray structure capable of adjusting size and self-filling expansion joint gap when implemented, which is composed of a bottom plate 1, a driving block one 2, a driving block two 3, a connecting assembly 4 and a chain plate mechanism 5, so as to realize continuous, smooth and damage-free conveying of mobile phone screens of different sizes without stopping and replacing the tray tooling, so that the detection efficiency of mobile phone screens is significantly improved. The sliding out of the top strip 441 and the top block 451 in the first top block mechanism 44 and the second top block mechanism 45 is a passive response to the ejection, that is, the ejection occurs when the push strip 445 and the push block 455 are separated from the containing cavity one 21 and the containing cavity two 11, so that the empty gap can be automatically filled without additional control of the ejection. The chain plate mechanism 5 realizes the space conversion between the lower part and the upper part of the bottom plate 1 through the cavity 23 and the rotating roller 232, and when the conversion is performed, the chain plate mechanism 5 in the cavity 23 is a flexible chain plate, and each section of the support plate 51 in the chain plate mechanism 5 that slides out of the cavity 23 is locked by the T-shaped plate 24 and the T-shaped groove 511, so that the chain plate mechanism 5 that slides out of the cavity 23 can form a rigid support plane, and the chain plate mechanism 5 can fill the gap between the driving block one 2 and the driving block two 3 through the rigid-flexible switching mode when the driving block one 2 and the driving block two 3 are separated from the bottom plate 1, and can be retracted to the lower side of the bottom plate 1 when the driving block one 2 and the driving block two 3 are attached to the bottom plate 1.
