[0034] It should be noted that the reference plate 3 is a flat plate with high surface accuracy and good flatness, which can be used as a reference standard, so that when the surface of the thin sheet material is closely attached to the surface of the reference plate 3, the surface of the thin sheet material is leveled, and the surface of the thin sheet material is closely attached to the surface of the reference plate 3 by adjusting the posture of the positioning and leveling plate 8 by the leveling component 021, which can achieve rapid leveling of the processing surface of the thin sheet material.

[0035] It should be noted that the reference plate 3 is used to level the processing surface of the thin sheet material. The surface of the reference plate 3 provides an accurate reference surface, so that the leveling of all thin sheet materials is based on the high-precision standard reference plate 3, which can effectively achieve precise control of the processing surface of the thin sheet material, thereby improving the processing accuracy.

The positioning and adjusting plate 8 contacts the ball head through its positioning portion, and adjusts the posture of the positioning and adjusting plate 8 through the adaptive compression of the elastic parts 20 on at least three leveling rods 18 to ensure that the processing surface of the thin sheet material is fully fitted with the surface of the reference plate 3, thereby achieving adaptive leveling of the processing surface of the thin sheet material.

[0042] Optionally, the first driving component 10 includes a substrate cylinder, which is disposed on the bottom plate 1 , and the leveling substrate 9 is arranged horizontally and connected to a piston rod of the substrate cylinder, and the substrate cylinder is used to drive the leveling substrate 9 to rise and fall.

The locking member 21 adopts a stop piston rod. The leveling substrate 9 is provided with a mounting hole for installing the leveling rod 18. A first air flow cavity arranged in a horizontal direction and connected to the mounting hole is constructed in the leveling substrate 9. The stop piston rod is passed through the first air flow cavity. The leveling substrate 9 has a first air port 26 connected to the first air flow cavity. The first air port 26 is connected to a pneumatic joint, and air is supplied to the first air flow cavity through the pneumatic joint to push the stop piston rod to move close to the leveling rod 18 and support the leveling rod 18, thereby realizing the fixation of the positioning and adjusting plate 8.

[0071] The positioning assembly 022 includes two positioning components arranged relatively to each other, each positioning component includes a moving part 15 and a positioning part 13, the positioning and adjusting plate 8 is provided with two installation cavities, the two moving parts 15 are respectively arranged in the two installation cavities, the moving part 15 adopts a positioning piston rod, one end of the positioning piston rod is slidably arranged in the installation cavity, the positioning part 13 is arranged at the other end of the positioning piston rod, and a second air flow cavity is formed between the two installation cavities.

[0072] The working process of the sheet material feeding device in this embodiment: like Figure 1 As shown, in the initial state, the reference plate 3 is located at the second position, and the adjustment mechanism 02 is in a horizontal state and located at the installation position. The adjustment mechanism 02 installed thereon is driven by the rotary cylinder to rotate 90°, so that the positioning adjustment plate 8 is in a vertical state.

[0073] When the positioning and adjusting plate 8 is in a vertical state, facing the material bin, the base plate cylinder pushes the leveling base plate 9 and the positioning and adjusting plate 8 to move toward the material bin and makes the surface of the positioning and adjusting plate 8 contact with the thin material. The positioning and adjusting plate 8 contacts with the ball heads of the three leveling rods 18 through the conical groove 28 and the V-groove 29 on its bottom surface, which is a six-degree-of-freedom fit. Through the adaptive compression of the three elastic parts 20, it can be ensured that the surface of the positioning and adjusting plate 8 is completely fitted with the thin material and the positioning and adjusting plate 8 will not be displaced in the vertical direction. The vacuum pressure is connected inside the positioning and adjusting plate 8, and the thin material is adsorbed on the surface of the positioning and adjusting plate 8 through the adsorption port 31.

[0074] The substrate cylinder retracts, and the rotating cylinder rotates 90° in the opposite direction to reset to the initial state; the second air port 32 of the positioning and adjusting plate 8 is connected to the vacuum pressure, and the positioning piston rod drives the positioning member 13 to move under the vacuum pressure to position the thin sheet material. The movement speed of the positioning member 13 can be adjusted by controlling the vacuum flow to ensure that the thin sheet material will not be deformed.

[0075] The reference plate cylinder pushes the reference plate 3 to move above the positioning and adjustment plate 8, that is, to the first position; the base plate cylinder pushes the positioning and adjustment plate 8 and the thin sheet material to move upward and make the surface of the positioning and adjustment plate 8 contact with the reference plate 3. The positioning and adjustment plate 8 contacts the ball heads of the three leveling rods 18 through the conical groove 28 and the V-groove 29 on its bottom surface, which is a six-degree-of-freedom fit. Through the adaptive compression of the three elastic parts 20, it can ensure that the processing surface (upper surface) of the thin sheet material is fully fitted with the lower surface of the reference plate 3, thereby realizing adaptive leveling of the processing surface of the thin sheet material.

[0076] The first air port 26 of the leveling base plate 9 receives air pressure to push the stop piston rod to move, and the stop piston rod presses against the leveling rod 18 through the opening on one side of the leveling rod bushing 19, thereby fixing the leveling rod 18 to achieve positioning of the leveling plate 8.

[0077] The reference plate cylinder retracts, the reference plate 3 is reset to the second position, and the sheet material is separated from the reference plate 3; the base plate cylinder drives the positioning and leveling plate 8 to retract, thereby completing the loading, positioning and leveling of the sheet material.
