The silo frame 1 is connected to one end of the loading tray 22 through a connecting shaft, and the bottom surface of the other end of the loading tray 22 is hingedly connected to the telescopic end of the cylinder A (21). The cylinder A (21) is connected to the silo frame 1. The silo frame 1 is provided with a cylinder B (23) on the side away from the cylinder A (21). The cylinder B (23) is connected to the slider 36 in the loading adjustment part, wherein the loading adjustment part is arranged between the loading tray 22 and the loading waiting seat 4, wherein the loading waiting seat 4 is arranged to have an inclined structure on the side close to the loading adjustment part.

[0037] The base 31 in the feeding adjustment part is fixed to the silo frame 1 by bolts, and a bearing seat 32 is provided on the upper end of the base 31. The bearing seat 32 is connected to the rotating shaft 33 through a bearing, and a feeding tray 34 is respectively provided at both ends of the rotating shaft 33. A ratchet 35 is provided on the rotating shaft 33, and a slider 36 is provided beside the ratchet 35. The first connecting shaft 231 provided on the slider 36 is connected to the telescopic end of the cylinder B (23), and the first connecting shaft 231 is connected to the ratchet pawl 351. The ratchet pawl 351 is contacted and connected to the ratchet 35. The other end of the slider 36 is slidably connected to the slide rail 37 installed on the base 31, wherein a plurality of arc grooves 341 are arranged at intervals on the outer edge of the feeding tray 34, and the arc grooves 341 of the feeding tray 34 are adapted to the blank 100.

[0038] The silo frame 1 is located at the upper layer of the loading assembly, and the unloading assembly and the unloading waiting seat 6 are installed at the side thereof. The unloading tray 52 in the unloading assembly is fixedly installed on the silo frame 1. The silo frame 1 is provided with an installation cylinder C (51) at the side close to the unloading waiting seat 6. The output end of the cylinder C (51) is connected to one end of the power plate 53. The other end of the power plate 53 is provided with vertical blocks 531 on both sides.

[0039] like Figure 8 and 9 The frame mechanism consists of a longitudinal linear module 71, a transverse linear module 72 and a clamping assembly. The longitudinal linear module 71 and the transverse linear module 72 are installed perpendicular to each other, and the clamping assembly is installed on the longitudinal linear module 71. The longitudinal linear module 71 and the transverse linear module 72 have the same structure. The longitudinal linear module 71 and the transverse linear module 72 are composed of a servo motor 102, a belt, an active roller, a driven roller, a slider and a mounting frame. The servo motor 102 drives the belt to move through the roller to control the linear movement of the slider. The linear module is an existing equipment and can be purchased directly, so this application will not describe it in detail.

[0040] The clamping assembly includes a cylinder F (81), a connecting seat 82, a positioning pressure block 93, a clamping cylinder 91, and a clamping pressure block 92. The telescopic end of the cylinder F (81) is connected to the connecting seat 82. Positioning pressure blocks 93 are respectively provided on both sides of the other end of the connecting seat 82. A clamping pressure block 92 is provided at a relative position above the positioning pressure block 93. The clamping pressure block 92 is connected to the clamping cylinder 91. The clamping cylinder 91 adopts a rotary clamping cylinder. The rotary clamping cylinder is an existing commercially available equipment, so it is not described in detail in this application.

[0041] Example 2

[0042] The electronic components in this utility model are all electrically connected to the overall control system for blank processing and production, and the operation of the electronic components is controlled by the controller in the overall control system.

[0043] When the blank is being processed and loaded, the cylinder A (21) is started to control the loading tray 22 to tilt, so that the blank 100 on the loading tray 22 near the loading adjustment part starts to move due to the tilt of the tray, and moves to the arc groove 341 on the feeding tray 34. At this time, the cylinder B (23) is started, and the ratchet pawl 351 is controlled by the ejection of the cylinder B (23) to push the ratchet 35 to rotate. When the telescopic end of the cylinder B (23) moves downward, the ratchet pawl 351 is dropped to the other tooth surface on the ratchet 35, and rotates back and forth. By driving the ratchet 35 to rotate, the rotating shaft 33 is rotated, and then the feeding tray 34 is rotated. The blank 100 on the feeding tray 34 falls into the loading and taking seat 4, that is, the material is loaded to the waiting position. The clamping assembly in the rack mechanism arranged on the front side of the silo rack 1 is moved under the drive of the longitudinal linear module 71 and the transverse linear module 72 controlled by the servo motor 102. The cylinder F (81) starts to control the connection seat 82 to move forward and move to the blank 100. Then, the positioning clamp 93 and the clamping clamp 92 are located on both sides of the blank 100. Then the clamping cylinder 91 is started to control the clamping clamp 92 to move and complete the clamping of the blank 100 with the positioning clamp 93. Then, the linear module drives the clamping clamp 92 to move to the processing table.

[0044] During unloading, similarly, the finished workpiece 101 processed on the processing table is clamped by the clamping assembly, and then driven by the longitudinal linear module 71 and the transverse linear module 72 to move to the hopper rack 1, and placed on the unloading waiting seat 6 in the unloading assembly. Then, the cylinder C (51) is started and begins to telescopically move, controlling the movement of the power-assisting plate 53. The vertical block 531 of the power-assisting plate 53 pulls the finished workpiece 101 on the unloading waiting seat 6 toward the unloading tray 52, which is equivalent to giving the finished workpiece 101 a pulling force, that is, moving the material on the unloading waiting seat 6 to the unloading tray 52.

[0045] The above actions are performed repeatedly to carry out automatic loading and unloading operations of materials, thereby reducing manual labor intensity and improving processing production efficiency. Compared with industrial robots, the overall structure of this application is simple, the cost is low, and maintenance is convenient.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention.
