The working principle of the automatic visual recognition cutting machine is briefly described below:

before production, the operator can install the rolled sheet material 20 on the support bar 22 of the material feeding device 2 and place the sheet material 20 (e.g. leather) released from the support bar 22 on the advancing section 311 of the conveyor belt 31 between the upper clamping bar 322 and the conveyor belt 31; then, the upper clamping bar 322 is driven to descend by the clamping lifting mechanism 323, and the sheet material 20 is clamped and positioned by the forward section 311 of the conveyer belt 31 and the upper clamping bar 322 together (at this time, the lower supporting bar 321 plays a role in supporting the forward section 311 of the conveyer belt 31).

When the device is in operation, under the control of the control device 1, the forward section 311 of the conveyer belt 31 moves from front to back, meanwhile, the clamping and conveying assembly 32 is driven by the clamping and conveying mechanism 33 to translate from front to back, the flaky materials 20 are pulled by the conveyer belt 31 to move from front to back, and the flaky materials pass through the stations of the UV jet printing device 4 and the material cutting device 5 in sequence; when the sheet material 20 reaches the station of the UV jet printing device 4, the UV jet printer 41 is driven by the jet printing translation mechanism 42 to translate left and right, and pattern codes are printed on the sheet material 20 and typesetting and drawing are performed; when the sheet material 20 arrives at the station of the material cutting device 5, the control device 1 stops moving the forward section 311 of the conveying belt 31, the sheet material 20 on the conveying belt 31 is not shifted and retracted under the action of the clamping and conveying assembly 32, the front-back translation mechanism 53 and the left-right translation mechanism 55 respectively drive the visual recognition mechanism 57 to translate along the front-back direction and the left-right direction, in the translation process of the visual recognition mechanism 57, the light rays emitted by the annular LED light source 572 can illuminate the pattern character codes printed on the sheet material 20 on the material clamping and conveying device 3, and meanwhile, the visual camera 571 scans the pattern character codes printed on the sheet material 20, acquires the shapes and positions of the pattern character codes printed on the sheet material 20 and sends the pattern character codes to the control device 1; then, the control device 1 controls the front-back translation mechanism 53, the left-right translation mechanism 55 and the rotary driving mechanism 564 to respectively adjust the front-back, left-right and angle positions of the cutter die assembly 563 according to the shape and the position of the pattern character code printed on the sheet material 20, so that the cutting position of the cutter die assembly 563 is completely aligned with the pattern character code printed on the part to be cut of the sheet material 20, then controls the push rod of the electric cylinder 72 of the cutting lifting mechanism 562 to push out and drive the lower pressure plate 561 to descend, drives the rotary driving mechanism 564 and the cutter die assembly 563 to descend, so that the cutter die 5632 and the two material pressing plates 5633 are downwards pressed towards the part to be cut of the sheet material 20, and the height position of the material pressing plates 5633 is lower than that of the cutter die 5632, the pressing plates 5633 are mounted on the cutter die mounting plate 5633 through the pressing elastic columns 5634, so that when cutting the material, the two pressing plates 5633 are firstly contacted with the sheet material 20 to be cut, and the sheet material 20 is pressed under the elastic action of the pressing elastic columns 5634 to better fix the sheet material 20 (at this time, the pressing guide shafts 56341 of the two pressing elastic columns 5634 respectively move upwards along the corresponding fixing sleeves 56342, and apply the acting force to the pressing springs 56343 through the lower annular blocks 563411 to make the pressing springs 56343 to be compressed and deformed, at this time, the pressing plates 5633 can be clung to the sheet material 20 under the elastic action of the pressing springs 56343, and the rigid pressing of the pressing plates 5633 to crush the sheet material 20 can be avoided); after the cutting die 5632 and the two pressing plates 5633 press the sheet material 20, the supporting plate 71 and the electric cylinder 72 thereon are integrally lifted relative to the translation seat 54 under the reaction force until the top of the cylinder body of the electric cylinder 72 abuts against the upper tray 511, the upper tray 511 supports the pushing force generated by cutting the material by the electric cylinder 72, the push rod of the electric cylinder 72 is continuously pushed out to drive the cutting die assembly 563 to continuously descend, the sheet material 20 is cut into the sheet material with the pattern character codes by the punching force generated by the annular cutter 56322 of the cutting die 5632, the cutting action can be completed by better stress of the cutting die 5632 when the cutting material is cut, the product cutting qualification rate is improved, and the production requirement is met. After the cutting die cutting mechanism 56 completes one cutting of the sheet material 20, the control device 1 adjusts the position of the cutting die assembly 563 through the front-rear translation mechanism 53, the left-right translation mechanism 55, the cutting lifting mechanism 562 and the rotary driving mechanism 564, so that the position right above the next part to be cut of the sheet material 20 is moved, the next cutting action is prepared, and thus, the cutting die cutting mechanism 56 can automatically typeset and cut the sheet material 20. After the cutting die cutting mechanism 56 completes one typesetting and cutting, the clamping lifting mechanism 323 drives the upper clamping rod 322 to ascend so as to loosen the sheet-shaped material 20, and then the clamping assembly 32 is driven by the clamping translation mechanism 33 to translate and reset forwards, so that one feeding is completed.
