Detailed implementation manners

[0024] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Appendix Figures 1-4 The folding feeding device for liquid crystal screen panel production according to the present utility model includes a frame 1, two loading conveyor lines 2 and a return conveyor line 3 arranged side by side on the frame 1, a disassembly mechanism 4 arranged on the loading conveyor line 2 for disassembling stacked material boxes into one box at a time, and a box folding mechanism 5 arranged on the return conveyor line 3 for stacking empty material boxes together;

[0026] Both the loading conveyor line 2 and the return conveyor line 3 adopt roller conveyor lines, and the conveying directions are opposite;

[0027] The disassembly mechanism 4 and the box folding mechanism 5 have the same structure, and both include a lifting assembly 41 arranged below the roller conveyor line for lifting the material box on the roller conveyor line, and lifting assemblies 42 arranged above the roller conveyor line and on both sides of the lifting assembly 41 respectively;

[0028] Each of the lifting components 42 includes a lifting cylinder 421 vertically arranged on the side of the roller conveyor line, a clamping cylinder 422 horizontally arranged at the driving end of the lifting cylinder 421, and an L-shaped insertion plate 423 arranged at the driving end of the clamping cylinder 422; when the L-shaped insertion plate 423 is in the lowest position, it is just located between the lowermost material box and the penultimate material box on the roller conveyor line; after the lifting component 41 lifts the material box from the roller conveyor line, the lowermost material box is higher than the L-shaped insertion plate 423 in the lowest position.

[0029] When stacked material boxes are placed on the loading conveyor line 2, the loading conveyor line 2 will place the stacked material boxes into the disassembling mechanism 4, and the stacked material boxes are disassembled into individual boxes through the disassembling mechanism 4 and finally flow out; specifically: when the stacked material boxes are placed in the disassembling mechanism 4, the clamping cylinders 422 on both sides simultaneously drive the L-shaped insertion plates 423 to extend between the lowermost material box and the penultimate material box, and then the lifting cylinders 421 on both sides simultaneously drive the clamping cylinders 422 on both sides to rise, so that the L-shaped insertion plates 423 on both sides drive the penultimate material box and the material boxes above it to move upward and separate from the lowermost material box, and then the loading conveyor line 2 outputs the lowermost material box from the disassembling mechanism 4 for loading; then the lifting component 41 lifts from the loading conveyor line 2, and then the lifting cylinders 421 on both sides simultaneously drive the clamping cylinders 422 on both sides to descend, so that the L-shaped insertion plates 423 on both sides drive the just-lifted material box to descend until the material box lands on the lifting component 41, then the clamping cylinders 422 on both sides simultaneously drive the L-shaped insertion plates 423 to retract, and finally the lifting component 41 descends until the material box lands on the loading conveyor line 2, and so on in sequence until the last material box is output from the disassembling mechanism 4 by the loading conveyor line 2.

[0030] The structure of the box stacking mechanism 5 is the same as that of the disassembly mechanism 4, but the movement is opposite. After an empty box is conveyed to the return conveyor line 3, the return conveyor line 3 will place the empty box in the box stacking mechanism 5, and stack the empty boxes together through the box stacking mechanism 5, and finally flow out. Specifically, after the empty box is placed in the box stacking mechanism 5, the lifting assembly 41 lifts the empty box from the return conveyor line 3, and then the clamping cylinders 422 on both sides simultaneously drive the L-shaped inserting plates 423 to extend under the empty box. Then the lifting assembly 41 descends. During the descending process, the empty box will fall on the L-shaped inserting plates 423 on both sides. Then the lifting cylinders 421 on both sides simultaneously drive the clamping cylinders 422 on both sides to rise, so that the L-shaped inserting plates 423 on both sides drive the empty box to rise, avoiding interference with the subsequent empty boxes. When a new empty box is conveyed into the box stacking mechanism 5, the lifting cylinders 421 on both sides simultaneously drive the clamping cylinders 422 on both sides to descend, so that the L-shaped inserting plates 423 on both sides drive the previously lifted empty box to descend until it falls on the new empty box. Then the clamping cylinders 422 on both sides simultaneously drive the L-shaped inserting plates 423 to retract. Then the lifting assembly 41 lifts the two stacked boxes from the return conveyor line 3, and cycles in turn until the set stacking quantity is reached. Then the return conveyor line 3 outputs the stacked empty boxes from the box stacking mechanism 5.

[0031] Furthermore, each group of the lifting assemblies 42 further includes a positioning cylinder 424 horizontally arranged inside the lifting cylinder 421 and a clamping plate 425 vertically arranged at the driving end of the positioning cylinder 424.

During operation: the clamping plates 425 are driven by the positioning cylinders 424 on both sides to clamp the boxes, so that the stacked boxes can be placed as a whole and are not easily misaligned.

[0032] Furthermore, the lifting assembly 41 includes a support frame 411 arranged at the bottom of the roller conveyor line, a lifting plate 412 horizontally arranged between the support frame 411 and the bottom of the roller conveyor line, a plurality of guide rods 413 vertically arranged at the bottom of the lifting plate 412 and passing through the support frame 411, a lifting cylinder 414 vertically arranged at the bottom of the support frame 411 for driving the lifting plate 412 to lift and lower, and three lifting frames 415 vertically arranged on the lifting plate 412 and located between adjacent rollers. During operation: the lifting cylinder 414 drives the lifting plate 412 to drive the three lifting frames 415 to pass through the gaps between adjacent rollers, and lift the box from the roller conveyor line.

[0034] Further, both the loading conveyor line 2 and the material return conveyor line 3 include a feeding buffer zone 21, a folding and unfolding zone 22, and a discharging buffer zone 23; the roller conveyor line is controlled in sections in the feeding buffer zone 21, the folding and unfolding zone 22, and the discharging buffer zone 23, that is, each zone is driven separately by a motor, making folding and unfolding more convenient.
