[0026] During implementation, the electric push rod 22 inside the fixed cylinder 21 is controlled to work. Under the action of the electric push rod 22, the moving column 234 moves inside the fixed cylinder 21. At this time, the moving column 234 drives the guiding slider 233 to slide inside the guiding chute 231.

The surface of the lead screw 32 is fixed to the surface of the rotating shaft. An adjusting screw cylinder 334 is threadedly sleeved on the surface of the lead screw 32. A block 333 is installed on the surface of the adjusting screw cylinder 334. A groove 332 is opened on the inner wall of the loading rack 1. The groove 332 is slidably matched with the surface of the block 333. A fixed groove 31 is opened on the inner wall of the loading rack 1. The fixed groove 31 is slidably matched with the surface of the connecting frame 105. The surface of the connecting frame 105 is fixed to the surface of the adjusting screw cylinder 334.
[0028] During implementation, the driving motor 104 is controlled to operate. When the driving motor 104 operates, it drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the lead screw 32 to rotate inside the containing groove 331. When the lead screw 32 rotates, it drives the adjusting cylinder 334 to move inside the containing groove 331 in cooperation with the lead screw 32. When the adjusting cylinder 334 moves, it drives the block 333 to slide inside the groove 332. The adjusting cylinder 334 is guided by the combined action of the block 333 and the groove 332. When the adjusting cylinder 334 moves, it drives the connecting frame 105 to slide inside the fixed groove 31. The connecting frame 105 is guided by the fixed groove 31. When the connecting frame 105 moves, it drives the feeding box 103 and the glass plate 102 to move left and right to the required position for feeding the glass plate 102, so as to realize the high-efficiency feeding function of the feeding device.
[0029] Further, as Figure 2 and Figure 5 shown, a high-stability mechanism 4 is provided on the surface of the large suction cup 107 and the glass plate 102. The high-stability mechanism 4 includes a small suction cup 41, an L-shaped frame body 42, a mounting block 43, a positioning card 44 and a mounting screw 45. L-shaped frame bodies 42 are provided on both sides of the large suction cup 107. Small suction cups 41 are mounted on the surface of the L-shaped frame bodies 42. The surface of the small suction cup 41 is in contact with the surface of the glass plate 102. A mounting block 43 is mounted on the surface of the L-shaped frame body 42. A positioning card 44 is mounted on the surface of the mounting block 43. The positioning card 44 is engaged with the surface of the large suction cup 107. A mounting screw 45 is threadedly connected to the surface of the mounting block 43. One end of the mounting screw 45 passes through the mounting block 43 and is threadedly fastened to the surface of the large suction cup 107.
[0030] During implementation, the user places the L-shaped frame body 42 and the small suction cup 41 on the surface of the large suction cup 107 respectively, so that the L-shaped frame body 42 drives the mounting block 43 to move to one side of the large suction cup 107, and the mounting block 43 drives the positioning card 44 to be clamped to the surface of the large suction cup 107. The user tightens the mounting screw 45 on the surface of the mounting block 43. Under the action of the mounting screw 45, the L-shaped frame body 42 and the small suction cup 41 are mounted on the surface of the large suction cup 107. Under the action of the small suction cup 41, the stability of the glass plate 102 during feeding is higher, avoiding the phenomenon of the glass plate 102 falling, so as to realize the anti-falling function of the feeding device for the glass plate 102.
[0031] Working principle: When in use, first place the loading rack 1 at the designated position. The user operates the control button 110 on the surface of the precision engraving rack 101, so that the control button 110 controls the electric push rod 22 inside the fixed cylinder 21 to work. Under the action of the electric push rod 22, the moving column 234 moves inside the fixed cylinder 21. At this time, the moving column 234 drives the guiding slider 233 to slide inside the guiding chute 231. Under the combined action of the guiding chute 231 and the guiding slider 233, the moving column 234 is guided. When the guiding slider 233 moves inside the guiding chute 231, at this time, the rotating ball 232 rotates on the surface of the guiding slider 233. Under the action of the rotating ball 232, it is more labor-saving for the guiding slider 233 to move inside the guiding chute 231. Subsequently, when the moving column 234 moves, the moving column 234 drives the loading rack 1, the connecting frame 105 and the loading box 103 to move up and down to the required position, facilitating the loading of the glass plate 102, so as to realize the function of automatically adjusting the height of the loading device. Thus, when the loading device is in use, it can automatically adjust the loading height of the glass plate 102, making the automation degree of the loading device higher when in use.
[0032] Subsequently, the user operates the control button 110, so that the control button 110 controls the negative pressure pump 106 inside the fixed box 109 to work. Under the action of the negative pressure pump 106, the air inside the large suction cup 107 is sucked out, creating a negative pressure environment inside the large suction cup 107. Under the action of the large suction cup 107, the glass plate 102 is adsorbed.
[0033] Subsequently, the user places the L-shaped frame 42 and the small suction cup 41 on the surface of the large suction cup 107 respectively, so that the L-shaped frame 42 drives the mounting block 43 to move to one side of the large suction cup 107, and the mounting block 43 drives the positioning clip 44 to be clamped on the surface of the large suction cup 107. The user tightens the mounting screw 45 on the surface of the mounting block 43. Under the action of the mounting screw 45, the L-shaped frame 42 and the small suction cup 41 are mounted on the surface of the large suction cup 107. Under the action of the small suction cup 41, the stability of the glass plate 102 during loading is higher, avoiding the phenomenon of the glass plate 102 falling off, so as to realize the function of preventing the glass plate 102 from falling by the loading device. Thus, when the loading device is in use, it can stably adsorb the glass plate 102, avoiding the phenomenon of the glass plate 102 falling and being damaged during the use of the loading device, greatly improving the stability of the loading device when in use.
[0034] Subsequently, the user operates the control button 110, such that the control button 110 controls the operation of the control button 110. Under the action of the control button 110, the drive motor 104 is controlled to operate. When the drive motor 104 operates, the drive motor 104 drives the rotating shaft to rotate. When the rotating shaft rotates, the rotating shaft drives the lead screw 32 to rotate inside the containing groove 331. When the lead screw 32 rotates, under the cooperation of the lead screw 32 and the adjusting barrel 334, the adjusting barrel 334 is driven to move inside the containing groove 331. When the adjusting barrel 334 moves, the adjusting barrel 334 drives the block 333 to slide inside the groove 332. Under the combined action of the block 333 and the groove 332, the adjusting barrel 334 is guided. When the adjusting barrel 334 moves, the adjusting barrel 334 drives the connecting frame 105 to slide inside the fixing groove 31. Under the action of the fixing groove 31, the connecting frame 105 is guided. When the connecting frame 105 moves, the connecting frame 105 drives the loading box 103 and the glass plate 102 to move left and right to the required position, and performs the loading process on the glass plate 102, so as to realize the function of efficient loading of the loading device, thereby greatly increasing the loading speed when the loading device is used, making the working efficiency of the loading device higher when in use, greatly saving the loading time of the glass plate 102, and finally completing the use work of the loading device.
