Nuts are embedded in the inner wall of the connecting cylinder 804, and the two nuts are internally threaded to the same first threaded rod 815. A driven wheel 816 is connected to the outer wall of the first threaded rod 815. A third motor 806 is connected to the top of the first connecting plate 807. The output shaft of the third motor 806 is connected to a driving wheel 817. One side of the driving wheel 817 meshes with one side of the driven wheel 816. A connecting plate 801 is connected to the far end of each of the two first connecting cylinders 804. A locking block 802 is connected to the bottom of the connecting plate 801. Two second fixing plates 810 are connected to the top of the second connecting plate 808. A sliding sleeve is embedded in each of the two second fixing plates 810, and a second connecting plate is slidably connected in each of the two sliding sleeves. The connecting cylinder 811 is slidably connected to two second connecting cylinders 811 with a limiting rod 809. The ends of the two second connecting cylinders 811 that are close to each other are connected to a limiting plate 818, and the ends of the two second connecting cylinders 811 that are far apart are respectively connected to one side of two connecting plates 801. A slot 803 is provided on one side of the locking block 802. Multiple fixing slots are provided on the top of the inner wall of the slot 803, and fixing rods 813 are slidably connected within the fixing slots. One end of each fixing rod 813 is connected to the same extrusion strip 814. A first spring 812 is sleeved on the outer wall of the fixing rod 813. The two ends of the first spring 812 are respectively connected to one side of the extrusion strip 814 and the top of the inner wall of the slot 803. One side of the extrusion strip 814 is attached to and slidably connected to one side of the inner wall of the slot 803. The bottom of the inner wall of the slot 803 and the bottom of the extrusion strip 814 are provided with anti-slip rubber, and the surface of the anti-slip rubber is provided with anti-slip ridges. The threaded seat 6 is embedded with a sliding sleeve, and a sliding rod 4 is slidably connected in the sliding sleeve. The two ends of the sliding rod 4 are respectively connected to the two sides of the inner wall of the fixed frame 2. The threaded seat 6 is threadedly connected with a second threaded rod 11. One side of the inner wall of the fixed frame 2 is embedded with a bearing, and a rotating shaft is rotatably connected in the bearing.

The output shaft of the first motor 1 extends into the fixed frame 2 and is connected to the other end of the second threaded rod 11.

[0040] The specific implementation method is as follows: By setting up an anti-fall device 8, when the device is transporting the LCD module, the output shaft of the third motor 806 rotates, driving the drive wheel 817 to rotate, which in turn drives the driven wheel 816 to rotate. The driven wheel 816 rotates, driving the first threaded rod 815 to rotate, which in turn causes the first connecting cylinders 804 at both ends to move forward through the embedded nuts, causing the first threaded rod 815 to rotate. Then, the first connecting cylinders 804 drive the connecting plate 801, and the connecting plate 801 drives the locking block 802 to move inward, so that the LCD module is locked into the locking slot 803. By setting up a pressing strip 814, when the LCD module is locked into the locking slot 803, the pressing strip 814 is pressed, so that the pressing strip 814... 14 moves upward and compresses the first spring 812. When it is in place, the rebound force of the first spring 812 causes the extrusion strip 814 to contact and fix the liquid crystal module, thereby fixing the two liquid crystal modules and preventing the liquid crystal modules from falling off due to sudden unloading of the suction force during operation. Furthermore, by setting the second connecting cylinder 811, the limiting fixation of the second connecting cylinder 811 makes the movement of the connecting plate 801 driving the clamping block 802 more stable and can also improve the stability during clamping. By setting the limiting plate 818, the excessive outward movement of the second connecting cylinder 811 is prevented from affecting the normal operation of the device. By setting the anti-slip rubber, the extrusion strip 814 is prevented from making hard contact with the liquid crystal module and causing damage to the surface of the liquid crystal module.

[0041] The adjusting device 7 includes a connecting box 707, with a mounting box 702 connected to the top of the connecting box 707. A second motor 703 is fixedly installed inside the mounting box 702. The output shaft of the second motor 703 is connected to a gear 704. Two racks 708 mesh with the outer side of the gear 704. One end of each rack 708 is connected to a connecting rod 709. The end of the connecting rod 709 away from the racks 708 is connected to a conveying plate 705. An outer connecting pipe 701 is provided on the top of the conveying plate 705. One end of the outer connecting pipe 701 passes through the conveying plate 705 and is connected to a suction cup 706. Connecting grooves 712 are provided on both sides of the connecting box 707. The inner wall of the connecting groove 712 is... A slider 711 is connected to the side, and a groove 710 is opened on one side of the rack 708. The outer wall of the slider 711 is slidably connected to the inner wall of the groove 710. The cross-sections of the groove 710 and the slider 711 are both trapezoidal. The output shaft of the second motor 703 extends into the connecting box 707. A bearing is embedded in the bottom of the inner wall of the connecting box 707, and a rotating shaft is rotatably connected inside the bearing. One end of the rotating shaft is connected to the bottom of the gear 704. The outer wall of the rack 708 is slidably connected to the inner wall of the connecting groove 712. The top of the mounting box 702 is connected to the push rod of the electric push rod 5, and the top of the connecting box 707 is connected to the bottom of the first connecting plate 807 and the second connecting plate 808.

[0042] The specific implementation method is as follows: By setting an adjustment device 7, the output shaft of the second motor 703 rotates to drive the gear 704 to rotate, which in turn causes the gear 704 to drive the racks 708 on both sides to move. The racks 708 drive the connecting rod 709 to move, which in turn causes the connecting rod 709 to drive the two transport plates 705 to move towards each other. This allows the distance between the two transport plates 705 to be adjusted, enabling the device to transport LCD modules of different sizes. This avoids the need to change the transport components when transporting LCD modules of different sizes, thereby improving the applicability of the device. By setting the slider 711 to slide within the slide groove 710, the movement of the rack 708 is more stable, avoiding deviation and jamming. Furthermore, by setting the cross-sections of the slide groove 710 and the slider 711 to be trapezoidal, the slider 711 provides a limiting and fixing effect on the rack 708 when sliding within the slide groove 710, further improving stability.

[0043] The bottom of the upright plate 3 is provided with a movable shock-absorbing device 9, which includes two connecting blocks 903 and a support plate 904 connected between the two connecting blocks 903. Two telescopic rods 906 are connected to the top of the support plate 904. A second spring 905 is sleeved on the outer wall of the telescopic rod 906. Multiple insertion slots 901 are opened on the top of the connecting blocks 903. Limit pins 907 are slidably connected to the inner wall of the insertion slots 901. Two moving wheels 902 are rotatably connected to the opposite side of the two connecting blocks 903. The outer walls of the multiple moving wheels 902 are in contact with the limit track 10. One end of the telescopic rod 906 is connected to the bottom of the upright plate 3. The two ends of the second spring 905 are respectively connected to the top of the support plate 904 and the bottom of the upright plate 3. One end of each of the multiple limit pins 907 is connected to the bottom of the upright plate 3.

[0044] The specific implementation method is as follows: By setting a movable shock absorption device 9, the vibration generated when the device moves is transmitted to the second spring 905 through the support plate 904, and then the second spring 905 absorbs the vibration by contracting, so as to prevent the liquid crystal module from shaking due to vibration when the device is transported, and thus prevent the liquid crystal module from being damaged by shaking. By setting a telescopic rod 906, the second spring 905 is prevented from bending when it contracts, which affects the elasticity of the second spring 905. By setting a fixing pin, the stability between the upright plate 3 and the connecting block 903 is improved, thereby improving the stability of the device.

[0045] Working Principle: In use, the output shaft of the first motor 1 rotates, driving the second threaded rod 11 to rotate. The second threaded rod 11 moves the threaded seat 6, which in turn moves the electric push rod 5 to the desired position. The electric push rod 5 then moves the bottom connecting box 707. The output shaft of the second motor 703 then rotates, driving the gear 704 to rotate. The gear 704 moves the racks 708 on both sides, which in turn moves the connecting rod 709. The connecting rod 709 moves the two transport plates 705, allowing the distance between the two transport plates 705 to be adjusted. This enables the device to transport LCD modules of different sizes, increasing its applicability. When the suction cup 706 adheres to the LCD module, the top cover retracts via the electric push rod 5, moving the LCD module upwards. Simultaneously, the third... The output shaft of motor 806 drives the drive wheel 817 to rotate, which in turn drives the driven wheel 816 to rotate. The driven wheel 816 drives the first threaded rod 815 to rotate, which in turn causes the first connecting cylinders 804 at both ends to move towards each other. Then, the first connecting plate 807 drives the connecting plate 801 to move, and the connecting plate 801 drives the locking block 802 to move inward, so that the two sides of the LCD module are locked into the locking slots 803. The pressing bar 814 is fixed to the LCD module by the elastic force of the first spring 812, which prevents the LCD module from falling due to sudden unloading of the suction cup 706 when the LCD module is running, thus improving the stability during operation. Finally, the vibration generated during movement is transmitted to the second spring 905, which absorbs the vibration through extension and contraction, making the transfer more stable.
