[0033] It also includes a first middle-section conveying mechanism 14 arranged at the tail end of the first front-section cutting mechanism 4 and a second middle-section conveying mechanism 15 arranged at the tail end of the second front-section cutting mechanism 7. The first middle-section conveying mechanism 14 is used to convey the products cut by the first front-section cutting mechanism 4 to the first middle-section conveyor line 8 and the second middle-section conveyor line 9 according to the set rhythm, and the second middle-section conveying mechanism 15 is used to convey the products cut by the second front-section cutting mechanism 7 to the second middle-section conveyor line 9 and the third middle-section conveyor line 10 according to the set rhythm.

[0034] During the specific operation, the plate first flows in through the upstream equipment, and the product alignment is performed at the first feeding alignment mechanism 1 and the second feeding alignment mechanism 2. After the alignment is completed, the first front-section conveying mechanism 5 transports the product at the first feeding alignment mechanism 1 to the first front feeding line 3, and the second front-section conveying mechanism transports the product at the second feeding alignment mechanism 2 to the second front feeding line 6. Then, the first front feeding line 3 sends the product into the first front-section cutting mechanism 4 for the first cutting operation, and the second front feeding line 6 sends the product into the second front-section cutting mechanism 7 for the second cutting operation. Then, the first middle-section conveying mechanism 14 transports the products cut by the first front-section cutting mechanism 4 to the first middle-section conveyor line 8 and the second middle-section conveyor line 9 according to the set beat. The second middle-section conveying mechanism 15 is used to transport the products cut by the second front-section cutting mechanism 7 to the second middle-section conveyor line 9 and the third middle-section conveyor line 10 according to the set beat, so that the first rear-section cutting mechanism 11, the second rear-section cutting mechanism 12 and the third rear-section cutting mechanism 13 can simultaneously cut the plate.

[0035] In this structure, the provision of two front cutting channels and three rear cutting channels can effectively meet the needs of insufficient factory space and the requirement of not reducing production capacity.

[0036] In this embodiment, the first feed alignment mechanism 1 and the second feed alignment mechanism 2 each include a first conveying frame 101, and both sides and ends of the first conveying frame 101 are respectively provided with alignment rollers and first driving modules 103102 for driving the alignment rollers to move in the X-axis or Y-axis direction, and further include an air flotation mechanism provided on the first conveying frame 101;

[0037] It also includes a first conveying module located above the first conveying line body, the first conveying module includes a first conveying frame, the first conveying frame is provided with a first Y-axis drive module, the driving end of the first Y-axis drive module is provided with a first suction nozzle structure, the first suction nozzle structure is used to suck the product and transport the product from the first feeding alignment mechanism 1 and the second feeding alignment mechanism 2 to the first front-section cutting mechanism 4 or the second front-section cutting mechanism 7.

[0038] Specifically, when performing the feeding and alignment operation, the air flotation mechanism blows air into the plate so that the plate is in a floating state. The first driving modules 103102 around the first conveying frame 101 respectively drive the alignment rollers to move toward the plate so that the plate moves to the accurate position. Then, under the action of the first Y-axis driving module, the first suction nozzle structure sucks the plate and places the plate on the first front feeding line 3 or the second front feeding line 6.

[0039] In this structure, the position of the plate to be cut can be adjusted by setting the feeding alignment mechanism, thereby ensuring the accuracy of subsequent cutting.

[0040] In this embodiment, the first front feeding line 3, the second front feeding line 6, the first middle section conveying line 8, the second middle section conveying line 9 and the third middle section conveying line 10 all include a first belt transmission line and a transfer transmission line located at the rear end of the first belt transmission line;

[0041] The transfer transmission line includes a second conveying frame 301, on which a first conveying component 302 is provided for transporting products from the front end to the rear end of the second conveying frame 301, and a second conveying component 303 is provided at the rear end of the second conveying frame 301 for transporting products to the first front section cutting mechanism 4, the second front section cutting mechanism 7, the first rear section cutting mechanism 11, the second rear section cutting mechanism 12 or the third rear section cutting mechanism 13.

[0042] When the product is conveyed to the second conveying frame 301 by the previous workstation, the first conveying component 302 drives the product to move to the second conveying component 303 at the tail end of the second conveying frame 301, and the second conveying component 303 respectively delivers the plate to be cut into the first front section cutting mechanism 4, the second front section cutting mechanism 7, the first rear section cutting mechanism 11, the second rear section cutting mechanism 12 or the third rear section cutting mechanism 13.

[0043] In this structure, by arranging the second conveying assembly 303 at the rear end of the second conveying frame 301, the product can be directly conveyed into the cutting mechanism without the need to design an additional conveying mechanism.

[0045] Specifically, when the first conveying component 302 conveys the product, when the plate is located above the first vacuum table 3031, the first lifting drive structure drives the first vacuum table 3031 to rise and adsorb the plate. After the adsorption is firm, the second Y-axis drive module drives the first vacuum table 3031 to move along the Y-axis direction, so that the plate moves to above the second vacuum table. The second vacuum table adsorbs the product. Under the drive of the second Y-axis drive module, the plate is sent into the first front-section cutting mechanism 4, the second front-section cutting mechanism 7, the first rear-section cutting mechanism 11, the second rear-section cutting mechanism 12 or the third rear-section cutting mechanism 13 for cutting operation.

[0046] In this structure, the second conveying component 303 can be set to directly send the plate into the first front-section cutting mechanism 4, the second front-section cutting mechanism 7, the first rear-section cutting mechanism 11, the second rear-section cutting mechanism 12 or the third rear-section cutting mechanism 13, thereby reducing the space requirements and the setting of other conveying mechanisms.

[0047] In this embodiment, the first front-section cutting mechanism 4, the second front-section cutting mechanism 7, the first rear-section cutting mechanism 11, the second rear-section cutting mechanism 12 and the third rear-section cutting mechanism 13 all include a cutting frame 401, and the upper cutting head assembly 404403402 and the lower cutting head assembly are supported on the cutting frame 401, and the upper positioning camera and the lower positioning camera for positioning the cutting edge are symmetrically arranged on the cutting frame 401.

[0049] It should be explained that the above-mentioned cutting mechanism can be an existing module, and the positioning camera and cutting head used therein can be purchased directly. For example, the cutting head purchased is a standard part of Japan's MDI company, which can realize pressure detection during cutting. During specific operation, the plate is fed into the cutting frame 401, and the upper positioning camera and the lower positioning camera identify the cutting edge of the plate. The upper and lower cutter heads adjust the Y-axis tool according to the set formula. Sometimes the cutter wheel may be aligned, and sometimes the cutter wheel may be eccentric. After completing the preparation work, the upper and lower cutter wheels are driven by the X-axis linear motor to cut the product to ensure the accuracy of the product cutting.

[0050] At the same time, a receiving box for receiving the fragments is also provided at the lower part of the cutting frame 401. The receiving box is provided with steel blades driven by a motor to chop the fragments in the receiving box.

[0052] The suction cup transport structure 1403 includes a rotary drive assembly, a driving end of the rotary drive assembly is provided with a suction cup mounting frame, and the suction cup mounting frame is provided with a plurality of first suction cup structures for sucking products.

[0053] During specific operation, the first middle-section conveying mechanism 14 conveys the products cut by the first front-section cutting mechanism 4 to the first middle-section conveyor line 8 and the second middle-section conveyor line 9 according to the set rhythm, and the second middle-section conveying mechanism 15 conveys the products cut by the second front-section cutting mechanism 7 to the second middle-section conveyor line 9 and the third middle-section conveyor line 10 according to the set rhythm.

[0054] That is, during specific transportation, the suction cup transportation structure 1403 sucks the plate under the drive of the XY axis drive module 1402, and lowers the plate to the first middle section conveyor line 8, the second middle section conveyor line 9 or the third middle section conveyor line 10 according to the set rhythm under the drive of the XY axis drive module 1402 and the rotation drive component, so as to realize the distribution of the plate while rotating the plate 90 degrees.

[0055] The setting of this structure can realize the separation of products after the first cutting, and reduce the waiting time of the plates in the whole process by corresponding two first cutting lines to three second cutting lines, thereby ensuring the production efficiency of the whole production line.

A plurality of second suction cup structures 1604 and a plurality of supporting pins 1605 are provided on the rotating frame 1601.

[0060] Specifically, after the second suction cutting, the products are respectively conveyed to their respective second belt transmission lines 16, and the second belt transmission line conveys the products forward to the tail end, and the rotating frame lifting cylinder 1603 drives the rotating frame 1601 to rise and contact the products, and the second suction cup structure 1604 adsorbs the products, and the rotating frame lifting cylinder 1603 drives the rotating frame 1601 to rotate the products to the specified angle. When the rotation is completed, the rotating frame lifting cylinder 1603 drives the rotating frame 1601 to descend, so that the products fall on the second belt transmission line 16, and then under the drive of the second belt transmission line 16, the products are conveyed to the transfer output line 17 and flow from the transfer conveyor line to the next workstation.
