[0051] The comb-tooth tenoning machine 910 is arranged on both sides of the second synchronous conveyor belt 900. The comb-tooth tenoning machine 910 is an existing commonly used equipment so its structure is not described in detail. The comb-tooth tenoning machine 910 is used to perform tenoning operations on the materials transported by the second synchronous conveyor belt 900.

[0052] The working principle of the sofa L-shaped foot full-automatic production line provided in the embodiment of the present application is as follows: the operator first controls the translation motor 160 of the loading device 100 to drive the translation gear 170 to rotate, so as to drive the rack 180 meshed with the translation gear 170 to rotate and drive the translation platform 130 to move away from the first synchronous conveyor belt 300, thereby driving the translation cylinder 140, the positioning cylinder 120 and the support plate 110 connected to the translation platform 130 to move away from the first synchronous conveyor belt 300. At this time, the operator can move the eight height-adjustable The sofa L-shaped feet to be processed materials stacked in sequence are placed between the two support plates 110, and the translation motor 160 of the loading device 100 is controlled to drive the translation gear 170 to rotate in the opposite direction, so that the translation cylinder 140, the positioning cylinder 120 and the support plate 110 connected to the translation table 130 move toward the direction close to the first synchronous conveyor belt 300, and the eight stacked sofa L-shaped feet to be processed are fixed by the two support plates 110 to prepare for unloading. At this time, the length direction of the sofa L-shaped feet to be processed is perpendicular to the conveying direction of the first synchronous conveyor belt 300.

[0053] Subsequently, the first synchronous conveyor belt 300 starts to drive the positioning and rotating device 200 to move below the sofa L-shaped foot material to be processed and then stops operating. The two positioning cylinders 120 respectively drive the cylinder rods to retract and drive the two support plates 110 to move away from each other, so that the eight stacked sofa L-shaped foot materials to be processed are dropped onto the positioning seat 210 of the positioning and rotating device 200, and the bottom sofa L-shaped foot material to be processed is located between the first positioning plate 230 and the second positioning plate 250. Subsequently, the two positioning cylinders 120 respectively drive the cylinder rods to extend and drive the two support plates 110 to move towards each other to re-fix the seven sofa L-shaped foot materials to be processed stacked from top to bottom. The clamping cylinder 240 of the positioning and rotating device 200 drives the second positioning plate 250 to move toward the first positioning plate 230, and the first positioning plate 230 and the second positioning plate 250 are used to clamp the sofa L-shaped foot material to be processed, thereby realizing the loading and positioning of the sofa L-shaped foot material to be processed.

[0054] The first synchronous conveyor belt 300 starts to drive the positioning rotating device 200 and the sofa L-shaped foot material to be processed fixed thereon to move to the side of the slot milling machine 400 and then stops working. At the same time, the first rotating cylinder 220 of the positioning rotating device 200 drives the positioning seat 210 to rotate 90 degrees, so that the length direction of the L-shaped foot material to be processed is parallel to the conveying direction of the first synchronous conveyor belt 300. The slot milling machine 400 is used to perform slot milling on the L-shaped foot material to be processed. Then, the first synchronous conveyor belt 300 starts to drive the positioning rotating device 200 and the sofa L-shaped foot material to be processed fixed thereon to move to the punching machine. After the device 500 moves sideways, it stops operating to drill holes. The first rodless cylinder 510 drives the first slider 511 and the second rodless cylinder 520, the punching seat 530 and the drilling motor 540 connected thereto to move along the length direction of the L-shaped leg material to be processed to the drilling position. The second rodless cylinder 520 drives the second slider and the punching seat 530 and the drilling motor 540 connected thereto to move toward the direction close to the L-shaped leg material to be processed, and drives the drill bit 550 through the drilling motor 540 to drill holes in the side of the L-shaped leg material to be processed. The above process is repeated to open the required holes in the side of the L-shaped leg material to be processed.

[0055] The first synchronous conveyor belt 300 starts to drive the positioning and rotating device 200 and the fixed sofa L-shaped foot to be processed material to move to the side of the material turning device 600 and then stops operating to turn over. At the same time, the first rotating cylinder 220 of the positioning and rotating device 200 drives the positioning seat 210 to rotate 90 degrees in the opposite direction, so that the length direction of the L-shaped foot to be processed material is perpendicular to the conveying direction of the first synchronous conveyor belt 300. The clamping cylinder 240 drives the second positioning plate 250 to move away from the first positioning plate 230 to release the sofa L-shaped foot to be processed material. The third rodless cylinder 640 drives the second rotating cylinder 630 and the second rotating cylinder 630 and the limit plate 610 connected to it to move towards the direction of the L-shaped foot to be processed material, so as to use the two limit plates 610 to press the two ends of the L-shaped foot to be processed respectively for limiting. The rotating cylinder 630 drives the two limit plates 610 to rotate 90 degrees in the vertical direction, so that the side of the L-shaped foot material to be processed with the opening is arranged upward, the third rodless cylinder 640 drives the second rotating cylinder 630 and the second rotating cylinder 630 and the limit plate 610 connected thereto move away from the L-shaped foot material to be processed and stop limiting, the clamping cylinder 240 drives the second positioning plate 250 to move toward the first positioning plate 230 to re-fix the sofa L-shaped foot material to be processed, the first rotating cylinder 220 drives the positioning seat 210 to rotate 90 degrees, so that the length direction of the L-shaped foot material to be processed is parallel to the conveying direction of the first synchronous conveyor belt 300, the first synchronous conveyor belt 300 starts to drive the positioning rotating device 200 and the fixed sofa L-shaped foot material to be processed to the side of the cutting device 700 and then stops operating for cutting.

[0056] The fourth rodless cylinder 710 of the cutting device 700 drives the fourth slider 711 and the fifth rodless cylinder 720, the cutting seat 730 and the cutting motor 740 connected thereto to move along the length direction of the L-shaped leg to be processed to the cutting position, the fifth rodless cylinder 720 drives the fifth slider and the cutting seat 730 and the cutting motor 740 connected thereto to move toward the direction of the L-shaped leg to be processed, and drives the cutting blade 750 through the cutting motor 740 to cut the L-shaped leg to be processed into two sections, the above process is repeated to cut the L-shaped leg to be processed into the required number of sections, and then the manipulator 800 is used to clamp and move the L-shaped leg to be processed, the clamping claw cylinder 840 extends the cylinder rod to drive the clamping claw motor 830, the support arm 8 20 and the pneumatic clamp 810 are raised, and then the clamp motor 830 drives the support arm 820 and the pneumatic clamp 810 to rotate to above the L-shaped foot material to be processed after cutting, the clamp cylinder 840 retracts the cylinder rod to drive the pneumatic clamp 810 to descend to both sides of the L-shaped foot material to be processed after cutting, the pneumatic clamp 810 closes and clamps the L-shaped foot material to be processed, and then the clamp motor 830 drives the support arm 820 and the pneumatic clamp 810 to rotate 180 degrees to the second synchronous conveyor belt 900, the second synchronous conveyor belt 900 transports the cut L-shaped foot material to be processed to move in a straight line direction, and the comb tooth tenoning machine 910 is used to perform tenoning operations on the L-shaped foot material to be processed transported by the second synchronous conveyor belt 900.
