The mode is mainly manual operation, has high labor intensity and low carrying efficiency, also has great potential safety hazard, and is difficult to carry for plates with larger areas and thinner thickness, and the quality of the plates is reduced due to the fact that the plates are easy to deform and the requirement of mass production on a flow line is hardly met.

As shown in connection with fig. 1 and 3, running gear 200 includes a running beam 210, two uprights 220, a drive wheel assembly 230, and a driven wheel assembly 240.

The driving wheel assembly 230 and the driven wheel assembly 240 are used as power elements and are generally realized in a form of motor-driven rollers, but in the device, the two walking beams 210 are required to have a walking route on the same horizontal plane, so that the lifting device 500 can be ensured to drive the sucker device 400 to move in the vertical direction, and when the sucker device 400 contacts a plate, the sucker 460 of the sucker device 400 is uniformly contacted with the surface of the plate, and the adsorption stability is ensured; therefore, the fixed mechanism of the driving wheel assembly 230 is adopted in the present embodiment, and the driven wheel assembly 240 adopts an adjustable structure, so that the height of both ends of the single walking beam 210 can be adjusted, and the two walking beams 210 can be adjusted to be substantially on the same plane.

The beam member 300 is a frame structure formed by welding a plurality of tubes, such as rectangular steel tubes, and comprises a pair of parallel supporting beams and two bridging beams, wherein the two bridging beams are respectively and vertically arranged at two ends of the pair of supporting beams, and the connection between the beam member 300 and the travelling mechanism 200 is realized by respectively connecting the two ends of the bridging beams with the upper ends of two upright posts 220 of the same travelling mechanism 200.
The design point of the core of the invention is that the lifting device 500 is designed in the structure, the adjustment of the conveying direction is generally bidirectional, namely, the horizontal and vertical directions in the existing design, the structure is relatively complex, and mainly because the vertical movement of the plate lifting device is controlled to basically adopt a cantilever structure, the support stability is poor, the impact resistance and the unbalanced load viewing capability are weak, the plate lifting device can be moved to the gravity center of the plate to lift the plate by adding the horizontal movement structure, the adverse effect on equipment is reduced, but the effect of the mode is relatively small, the equipment structure is more complex, the error is larger, and the control difficulty is higher. In this way, the inventor has long-term practice and grope and summarize, changed the action form of the plate lifting device, abandoned the adjustment in the horizontal direction, and until the lifting device 500 is adopted to carry out vertical lifting movement, greatly improved the capability of overcoming the impact resistance and the unbalanced load resistance of the equipment, and no need to find the position of the gravity center of the plate, and the operation is simpler and more convenient.
The specific structure of the lifting device 500 used in this embodiment is shown in fig. 1, 7, 8 and 9, and mainly includes two vertical moving frames 510, two vertical fixing frames 530 and a lifting driving mechanism 540, where the two vertical fixing frames 530 are respectively fixed on two opposite sides of the beam member 300, the two vertical moving frames 510 are respectively connected with the two vertical fixing frames 530 through linear guide rail pairs, and the lifting driving mechanism 540 drives the vertical moving frames 510 to perform lifting motion.

The vertical moving frame 510 includes a guide rail beam 511, two pairs of sliding blocks 532 of two vertical fixing frames 530 provided with two parallel guide rails 512 on the guide rail beam 511 are respectively in sliding fit with the two guide rails 512 of the two vertical moving frames 510, and the sliding support stability is strong by adopting the sliding fit form of the two pairs of sliding blocks 532 and the double guide rails, and is beneficial to enhancing the impact resistance and the unbalanced load resistance of the whole lifting device 500. Meanwhile, the upper ends of the two vertically moving frames 510 are connected by the bridge frame 520, and the lower ends thereof are connected to the suction cup device 400.
Therefore, unlike the existing lifting device for the plate, that is, the lifting device 400 adopts the cantilever supporting structure, the embodiment adopts the closed lifting device 500 to support the lifting device 400, the rectangular closed frame is formed between the two vertical moving frames 510 and the bridging frame 520 in the lifting device 500 and the lifting device 400, which has stronger structural strength, the two vertical fixed frames 530 are fixed on two opposite sides of the beam part 300 in the rectangular frame, the two vertical fixed frames 530 are in sliding fit with the two vertical moving frames 510, so that vibration, shaking, impact and the like in the feeding direction along the track 100 can be effectively restrained and resisted, even the swinging force in the horizontal plane and the unbalanced load force during lifting of the plate can be well overcome, the adverse effects of these factors on the transmission of the lifting driving mechanism 540 can be reduced to a very low degree, the impact resistance and the unbalanced load resistance of the whole lifting device 500 can be greatly improved, the service life of the device is effectively prolonged, the horizontal moving mechanism is omitted, the lifting center of gravity is simplified, and the whole lifting device is not required to be used for searching for the transmission structure, and the operation is simpler.
Although the use of two vertically movable frames 510 and two vertically fixed frames 530 in combination improves the impact resistance of the system, it is desirable to have good synchronization between them, which would otherwise occur in the event of lift jams or jamming.
