[0037] Referring to Figures 1 to 6 The application discloses a glass blanking device, which comprises:

[0038] a rack 1;

[0039] a first conveying section 2 connected inside the rack 1, the first conveying section 2 conveying a plurality of stacked empty trays;

[0040] a second conveying section 3 connected outside the rack 1, and the second conveying section 3 being stacked with the first conveying section 2, the second conveying section 3 conveying a single tray loaded with a glass substrate;

[0041] a tray lifting group 4, the tray lifting group 4 comprising a conveying part 41 and a first lifting piece 42, the first lifting piece 42 being connected with the rack 1, the first lifting piece 42 driving the conveying part 41 to move up and down in the height direction, when the conveying part 41 is at a low position inside the rack 1, the conveying part 41 is butt-jointed with the first conveying section 2; when the conveying part 41 is raised inside the rack 1, the conveying part 41 drives the stacked empty trays to be raised to the outside of the rack 1;

The glass blanking device has a reasonable structure, greatly utilizes the space in the height direction through the stacked empty trays and the layered first conveying section 2 and the second conveying section 3, and reduces the floor area of the glass blanking device; and each part is integrally connected inside and on the upper surface of the outside of the rack 1, has a compact layout, and is convenient to use; the tray lifting group 4 and the tray taking and placing group 5 realize automatic tray supply, and improve the blanking efficiency of the glass substrate.

[0044] In this embodiment, specifically, the first lifting piece 42, the second lifting piece 52 and the first translation piece 53 are conventional linear driving elements such as linear motors, rotary motors-screws-rail combinations, etc.

[0045] In this embodiment, as shown in Figure 2 Specifically, the first conveying section 2 comprises a first conveying frame 21, a plurality of first conveying rollers 22 and a first conveying driving piece (not shown in the figure), the first conveying frame 21 is connected with the rack 1, the plurality of first conveying rollers 22 are rotationally connected with the first conveying frame 21, the first conveying driving piece is connected with the plurality of first conveying rollers 22, and the first conveying driving piece drives the plurality of first conveying rollers 22 to rotate in the same direction; specifically, the second conveying section 3 is provided with the same conveying structure as the first conveying section 2.

[0046] The conveying part 41 comprises a base 411, a second conveying frame 412, a plurality of second conveying rollers 413 and a second conveying driving piece (not shown in the figure), the base 411 is connected with the first lifting piece 42, the second conveying frame 412 is connected with the base 411, the plurality of second conveying rollers 413 are rotationally connected with the second conveying frame 412, the second conveying driving piece is connected with the plurality of second conveying rollers 413, and the second conveying driving piece drives the plurality of second conveying rollers 413 to rotate in the same direction.

[0047] In this embodiment, preferably, the first conveying section 2 further comprises a conveying limiting plate 23, the conveying limiting plate 23 is connected with the first conveying frame 21, and the conveying limiting plate 23 is arranged on both sides of the first conveying roller 22.

[0048] The conveying part 41 further comprises a docking limiting plate 414 connected with the second conveying frame 412, and the conveying limiting plate 23 and the docking limiting plate 414 are docked when the conveying part 41 is at the low position inside the frame 1.

[0049] By setting the conveying limiting plate 23 and the docking limiting plate 414, it is ensured that the multiple stacked empty trays can be smoothly moved from the first conveying section 2 to the conveying part 41. When the multiple stacked empty trays are conveyed on the first conveying section 2, the two sides are limited by the conveying limiting plate 23; when the multiple stacked empty trays are conveyed on the conveying part 41, the two sides are limited by the docking limiting plate 414, so as to prevent the moving path from being skewed and smoothly docked and transitioned.

[0050] In the embodiment, further, an end of the conveying limiting plate 23 is provided with a first guide part 24 inclined outward, one end of the docking limiting plate 414 is provided with a second guide part 415 inclined outward, and the first guide part 24 and the second guide part 415 are docked when the conveying limiting plate 23 and the docking limiting plate 414 are docked.

[0051] The first guide part 24 and the second guide part 415 are inclined to the side away from the conveying axis and are provided in a flared shape, so as to smoothly enable the multiple stacked empty trays to enter the conveying part 41 from the first conveying section 2. Even if the docking conveying is vibrated and the multiple stacked empty trays are skewed to a certain extent, the flared shape of the first guide part 24 and the second guide part 415 still enables the stacked empty trays to smoothly flow out of the first conveying section 2, reduces the risk of blockage and falling, and the skewed empty trays abut against the second guide part 415 and are guided to be straightened when flowing into the conveying part 41, so as to restore the state of being stacked in order, thereby facilitating subsequent ascending and receiving.

[0052] In the embodiment, preferably, the conveying part 41 further comprises a stop plate 416 connected with the base 411, and the stop plate 416 is arranged on the side of the multiple second conveying rollers 413 away from the first conveying roller 22.

[0053] By setting the stop plate 416 at the conveying end of the conveying part 41, it is prevented that the multiple stacked empty trays slide out of the second conveying roller 413 under the action of conveying inertia, the risk of falling is reduced, and the safety and reliability of the glass blanking device are improved.

Specifically, the distribution driving member 43 is a driving element such as a pneumatic cylinder or an oil cylinder.

[0055] When the plurality of stacked empty trays are conveyed to the conveying part 41, the first lifting member 42 drives the conveying part 41 and the empty trays to ascend layer by layer, and each time the empty trays ascend, the uppermost empty tray is moved to the outside of the rack 1 and then grabbed by the taking and placing part 51. However, due to the extrusion of the plurality of stacked empty trays and the conveying vibration, the adjacent two layers of empty trays are not easy to separate, and when the taking and placing part 51 grabs the uppermost empty tray, the lower empty tray is likely to be dragged to ascend and then fall off and separate. The distribution driving member 43 and the distribution plate 44 effectively improve this problem. When the first lifting member 42 drives the uppermost empty tray to move to the outside of the rack 1, the distribution driving member 43 drives the distribution plate 44 to extend, the distribution plate 44 is inserted into the corresponding notch on both sides of the tray, the notch of the tray is arranged at the lower position on both sides, so that the distribution plate 44 limits the movement of the lower tray, and when the taking and placing part 51 grabs the uppermost tray, the distribution plate 44 abuts against the adjacent lower tray to limit the movement, thereby smoothly separating the plurality of stacked trays and ensuring the reliable operation of the glass unloading device.

[0056] In the embodiment, as shown in Figure 1 and Figure 5 Specifically, the taking and placing part 51 comprises a taking and placing plate 511 connected with the second lifting member 52 and a plurality of first vacuum suction cups 512 connected with the taking and placing plate 511; the taking and placing plate 511 is provided with an avoiding groove, and the first lifting member 42 is arranged in the avoiding groove.

[0057] When the taking and placing part 51 grabs the uppermost tray, the first vacuum suction cup 512 abuts against the tray, the first vacuum suction cup 512 is connected with an external negative pressure equipment to generate a negative pressure to suck the tray; then the second lifting member 52 drives the taking and placing part 51 and the single tray to ascend and separate from the conveying part 41, and the first translation member 53 drives the single tray to move to above the second conveying section 3; then the second lifting member 52 drives the single tray to descend to the conveying surface of the second conveying section 3, the first vacuum suction cup 512 removes the negative pressure suction, and the empty tray is filled with the glass substrate on the position of the second conveying section 3.

[0059] The glass taking group 6 comprises a taking part 61 for grabbing the glass substrate, a third lifting member 62 connected with the taking part 61, and a second translation member 63 connected with the third lifting member 62 and the rack 1, and the second translation member 63 drives the third lifting member 62 and the taking part 61 to move to the position of the second conveying section 3.

[0060] In the embodiment, the third lifting member 62 and the second translation member 63 are conventional linear driving elements such as linear motors, rotary motor-screw-rail combinations, etc.

[0061] In the embodiment, preferably, the taking part 61 comprises a taking plate 611 connected with the third lifting member 62 and a plurality of second vacuum suction cups 612 connected with the taking plate 611.

[0062] When the glass substrate is unloaded, the second vacuum suction cups 612 abut against the glass substrate, and the second vacuum suction cups 612 are connected with external negative pressure equipment to generate negative pressure to suck the glass substrate; then the third lifting member 62 drives the glass substrate to be lifted, the second translation member 63 drives the glass substrate to move above an empty tray on the second conveying section 3, the third lifting member 62 drives the glass substrate to move into the tray, then the second vacuum suction cups 612 remove the negative pressure suction, and the glass substrate is loaded into the tray; the second conveying section 3 is started to convey the tray loaded with the glass substrate to a loading position.

[0063] In the embodiment, as shown in Figure 1 , preferably, the glass unloading device further comprises:
