At the same time, the transmission structure composed of the first movable member, the first connecting plate, the first carrier plate, and the first drive assembly, combined with the X-axis track and Y-axis track, enables the first suction claw group to flexibly move in multiple dimensions, accurately placing the cardboard in the specified position, greatly improving the efficiency and accuracy of suction and transportation.

[0030] The second folding mechanism 4 includes a second placing bed 41, and third guide rails 42 are provided on both sides of the second placing bed 41.

A second spring (not shown in the figure) is provided between the second fixed plate 44 and the second folding plate 45.

[0031] The power input ends of the two first movable components 22 are connected to the X-axis track through mechanical transmission, and the power input ends of the first suction claw group 27 are connected to the Y-axis track through mechanical transmission. The cardboard that needs to be wrapped is transported to the bottom of the monitoring camera module 63 through the conveyor belt 21. After the monitoring camera module 63 monitors the orientation of the cardboard, the two second driving components 28 are operated, and the two first movable components 22 move along the X-axis, driving the first suction claw group 27 to adjust to the same orientation as the cardboard. The first lifting mechanism 26 is operated, and after the first suction claw group 27 moves downward to absorb the cardboard, the first lifting mechanism 26 is operated again, and the first suction claw group 27 moves upward. The two second driving components 28 are operated, and the two first movable components move to a position parallel to the central axis of the conveyor belt 21, thereby realizing the straightening of the cardboard. The first driving component 25 rotates to realize the movement of the first suction claw group 27 along the Y-axis.

[0032] The third driving assembly 34 is located on the right side of the first suction assembly 2. The first suction assembly 2 cooperates to operate and places the cardboard with the edge paper glued thereon above the first folding plate 322. The third driving assembly 34 operates and the second connecting plate 33 drives the folding assembly 32 to move along the second guide rail, thereby realizing the folding and corner pressing activity of the present invention. During the folding and corner pressing work, the bottom end of the folding block 324 passes through the adjusting slot 3221 and is equipped with a corner pressing piece 3241 for pressing the corner during the folding and corner pressing work. The corner pressing piece 3241 flattens the folding corner, thereby realizing the synchronous execution of the folding and corner pressing work and the corner pressing work of the present invention. The fourth driving mechanism 323 operates to adjust the distance between the two folding blocks 324, thereby realizing the present invention is applicable to corner pressing work of cardboards of different specifications.

[0033] The power input end of the fourth guide rail is connected to the power output end of the first movable plate 53 through mechanical transmission. The sixth driving assembly 51 is running, and the fourth connecting plate 52 drives the first movable plate 53 to move along the fourth guide rail to above the first placement bed 31. The second lifting mechanism 54 is lifted and lowered, so that the second suction claw group 55 can suck the cardboards after the folding and cornering work on both sides. The sixth driving assembly 51 is running again, and the fourth connecting plate 52 drives the first movable plate 53 to move along the fourth guide rail to above the second placement bed 41, and then places the cardboards on both sides that have not been folded and cornered on top of the second folding plate 45. The fifth driving assembly is running, and the third connecting plate 43 drives the second folding plate 45 to realize the folding and cornering activity.

[0034] After the first suction mechanism 2 sucks the cardboard, it runs directly to the central axis (center) of the mechanism marked with three, and the component marked with three performs folding and corner pressing on the cardboard.

[0035] The image monitoring sensor (visual recognition sensor) is used to detect that the first suction mechanism 2 directly runs to the central axis (center) of the first folding mechanism 3 after sucking the cardboard.

[0036] When the folding and corner pressing work is completed, the first image sensor feeds back a signal, and the mechanism marked 5 starts to operate. The second image sensor feeds back a signal of the cardboard position, and the suction work is performed. The mechanism marked 5 moves to the center axis of the mechanism marked 4. The mechanism marked 5 sucks the cardboard and places it for the second folding and corner pressing activity.

[0037] These sensors all feed back signals to the PLC, which then controls the structures that need to be controlled.

[0038] The first suction mechanism, through a combination of a conveyor belt, through-holes, and a first vacuum pump, quickly and stably picks up cardboard and transports it along the conveyor belt. Furthermore, the transmission structure, comprised of the first movable member, first connecting plate, first carrier plate, and first drive assembly, works in conjunction with X- and Y-axis tracks to enable the first suction claw assembly to flexibly move in multiple dimensions, precisely placing the cardboard in the designated location. This significantly improves the efficiency and accuracy of both suction and transport, resulting in highly efficient suction and transport.

[0039] The through-holes of the first placement bed, combined with the second vacuum pump, securely hold the cardboard. Driven by the spring, fourth drive mechanism, and third drive assembly, the first folding plate, folding block, and angle-pressing components of the folding assembly accurately fold and press the cardboard at various angles and shapes, and can be flexibly adjusted to suit the cardboard specifications. The second folding plate of the second folding mechanism, driven by the spring and fifth drive assembly, further refines the folding and angle-pressing process, effectively ensuring the quality and precision of the edges on all four sides, and ensuring accurate folding and angle-pressing.

[0040] The monitoring camera module has a built-in visual recognition sensor for identifying cardboard. The monitoring camera module on the shielding cover assembly can monitor the orientation of the cardboard in real time, providing accurate data support for subsequent suction, folding and other operations, avoiding processing errors caused by cardboard position deviation, realizing intelligent production control, and improving the stability and reliability of the production process. It has the characteristics of intelligent monitoring and control.

[0041] The multiple guide rails (such as the first guide rail, the second guide rail, etc.) provided on the frame assembly cooperate with the drive assembly (such as the first drive assembly, the second drive assembly, etc.), which not only ensures the smoothness and accuracy of the operation of each moving part, but also enhances the stability of the entire equipment structure, reduces vibration and noise during the operation of the equipment, extends the service life of the equipment, ensures the reliable operation of the equipment, and has the characteristics of stable structure and reliable operation.

[0042] Each mechanism (the first suction mechanism, the first folding mechanism, the second folding mechanism, and the second suction mechanism) is connected by different drive components and guide rails, achieving automated collaborative operation. From cardboard suction, transportation, folding, corner pressing, to final collection, the entire process requires minimal human intervention. This high degree of automation effectively reduces labor costs, improves production efficiency, and adapts to the needs of large-scale industrial production, featuring flexible automated operation.
