[0027] refer to Figure 1-5 This utility model provides the following two technical solutions:

[0029] The feeding component 2 consists of a transmission component, a positioning component, an adsorption component, and a transmission component. The feeding component 2 includes an electric slide rail 21 located at the bottom of the support frame 1. The electric slide rail 21 is slidably connected to a movable frame 22 that provides support for adjusting the position of the positioning component, the adsorption component, and the transmission component. A first adsorption plate 23 for adsorbing the bottom of the board is rotatably connected to the lower center of the movable frame 22. The feeding component 2 also includes a second adsorption plate 24 located above the first adsorption plate 23 for adsorbing and positioning the upper surface of the board. A cross shaft 25 is coaxially fixedly connected to the top of the second adsorption plate 24. An adjustment component 26 is provided at the top of the movable frame 22 for adjusting the height of the cross shaft 25 and providing suction for the first adsorption plate 23 and the second adsorption plate 24. A drive component 27 is provided on the left side of the movable frame 22 for providing power for the synchronous rotation of the first adsorption plate 23 and the second adsorption plate 24.

The adjusting component 26 also includes a movable plate 264 rotatably connected to the top of the cross shaft 25.

After the plate is transferred to a suitable position on the first adsorption plate 23, the hydraulic cylinder assembly 263 drives the movable plate 264, the cross shaft 25, and the second adsorption plate 24 to move down, so that the second adsorption plate 24 presses the plate onto the first adsorption plate 23. The negative pressure pump 261 and the branch pipe 262 make the first adsorption plate 23 and the second adsorption plate 24 adsorb the two sides of the plate respectively.

[0032] The main difference between the second implementation method and the first implementation method is that:

[0033] The limiting component 3 includes a cylinder assembly 31 installed on the upper rear end of the support frame 1. A limiting strip 32 for vertically limiting the plate is provided along the X-axis at the bottom extended end of the cylinder assembly 31. A set of limiting frames 35 for horizontally limiting the plate are slidably connected to both sides of the limiting strip 32. Two sets of sliding rods are provided on the side of the support frame 1 near the limiting frames 35, and both sets of limiting frames 35 are slidably connected to the support frame 1. Each set of limiting frames 35 has a movable groove slidably connected to the limiting strip 32. The support frame 1 is rotatably connected to a mechanism for adjusting the distance between the two sets of limiting frames 35. The bidirectional screw 34 is provided on the left side of the support frame 1. The first motor 271 and the second motor 33 are both servo motors. The bidirectional screw 34 is threadedly connected to two sets of limit frames 35 and coaxially fixedly connected to the output end of the second motor 33. The cylinder assembly 31 cooperates with the limit strip 32 to limit the vertical side of the plate before it is connected to the feeding component 2. The second motor 33 cooperates with the bidirectional screw 34 and the limit frame 35 to limit the horizontal side of the plate, which helps the feeding component 2 to accurately position the center of the plate.

[0034] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0035] In use, the user transports the sheet material to be bent to the space between the limiting member 3 and the feeding member 2 on the upper side of the support frame 1 through an external transmission device. The cylinder assembly 31 is activated, and the cylinder assembly 31 limits the sheet material on the vertical side through the limiting strip 32. Then, the second motor 33 cooperates with the bidirectional screw 34 to drive the two sets of limiting frames 35 to slide along the limiting strip 32, so that the two sets of limiting frames 35 limit the sheet material horizontally along the X-axis and finely adjust the position of the sheet material along the Y-axis so that the rotating end of the sheet material is in contact with the upper end of the first adsorption plate 23. The hydraulic cylinder assembly 263 is activated, and the hydraulic cylinder assembly 263 drives the movable plate 264, the cross shaft 25, and the second adsorption plate 24 to move downward. After the sheet material of the second adsorption plate 24 touches the upper side of the first adsorption plate 23, the negative pressure pump 261 is turned on. The negative pressure pump 261 provides suction to the first adsorption plate 23 and the second adsorption plate 24 through the branch pipe 262, so that the upper and lower surfaces of the sheet material are firmly adsorbed and pressed.

[0036] The positions of the connecting components, such as the moving frame 22, the first adsorption plate 23, and the second adsorption plate 24, are adjusted by the electric slide rail 21, causing the positioning plate to move towards the intelligent flexible bending center. During this process, the plate gradually separates from the limiting component 3. After the plate is transferred to the bending end of the bending center, it is bent through the bending center. After the bending operation is completed, the bending end is separated from the bending center to a suitable distance, and the first motor 271 is started. The first motor 271 drives the first bevel gear assembly 273 and the second bevel gear assembly 274 through the pulley assembly 272. The first bevel gear assembly 273 drives the first adsorption plate 23 to rotate, and the second bevel gear assembly 274 drives the cross shaft 25 and the second adsorption plate 24 to rotate synchronously through the sleeve 275, so that the first adsorption plate 23 and the second adsorption plate 24 adjust the horizontal angle of both sides of the plate. After the plate angle is adjusted, the above bending operation is repeated. The electric slide rail 21 is existing technology, so its specific working principle and internal structure will not be described in detail.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
