[0023] Please refer to Figures 1 to 2 The present application discloses a roller conveyor lifting mechanism, which includes a roller conveyor line and a lifting assembly. The roller conveyor line is used to convey the degumming basket 20 along a first direction a.

[0024] The lifting assembly is located directly below one end of the roller conveyor line. The lifting assembly includes a pair of lifting plates 31 and a lifting structure that drives the pair of lifting plates 31 to extend or retract from below the roller conveyor line. A lifting portion 311 is recessed at the center of the top of each lifting plate 31. Limiting portions 312 are formed on both sides of the lifting portion 311, with at least a portion of the upper surface of the limiting portion 312 being higher than the upper surface of the lifting portion 311. A pair of lifting shafts 21 are provided at both ends of the degumming basket 20. The maximum distance between the pair of lifting shafts 21 is equal to the width of the lifting portion 311. It should be noted that the maximum distance here refers to the farthest horizontal distance between the two lifting shafts 21.

[0025] In one embodiment, the limiting part 312 is a right-angled triangle, and the inclined surface of the right-angled triangle is connected to the upper surface of the lifting part 311. The lifting part 311 and the two limiting parts 312 on both sides form a lifting groove that is lower in the middle and higher on both sides. This allows the lifting shaft 21 to slide down from the inclined surface to the connection between the inclined surface and the lifting part 311 when the lifting plate 31 lifts the degumming basket 20, and to be firmly held at the connection under its own weight. This achieves adaptive adjustment of the degumming basket 20 by the lifting plate 31, reducing the positioning accuracy requirements of the degumming basket 20. At the same time, it improves the fixing effect of the degumming basket 20.

[0026] In one embodiment, the roller conveyor line includes a support frame 10, a plurality of rollers 11 spaced apart on the top of the support frame 10 along a first direction a, and a power component (not shown) for driving the rollers 11 to rotate. The two ends of each roller 11 are rotatably connected to the support frame 10. The power component is a motor. The rollers 11 are positioned at a height lower than the top of the support frame 10. A degumming basket 20 is placed on the rollers 11. The motor drives the rollers 11 to rotate, thereby moving the degumming basket 20, which moves along the first direction a under the guidance of the support frame 10.

[0027] In one embodiment, a lifting cavity is formed at the bottom of the support frame 10, and a lifting assembly is disposed within the lifting cavity. By disposing of the lifting assembly within the lifting cavity, it is beneficial to reduce the footprint of the entire mechanism.

[0028] In one embodiment, the lifting structure includes a lifting cylinder 34 fixed on a support frame 10 and a connecting bracket connecting the lifting cylinder 34 and the lifting plate 31. A pair of lifting plates 31 are respectively fixed at both ends of the connecting bracket. The distance between the two lifting plates 31 is slightly larger than the length of the degumming basket 20, and the gap between the lifting plates 31 and the degumming basket 20 facilitates the insertion of the lifting plates 31 into both sides of the degumming basket 20 from bottom to top.

[0029] In one embodiment, the connecting bracket includes a connecting plate 33 extending along a first direction a and support plates 32 extending vertically at both ends of the connecting plate 33. The bottom of the lifting plate 31 is folded to form an L-shaped connecting portion for fixed connection with the top of the support plate 32, thereby increasing the connection area between the lifting plate 31 and the support plate 32 and improving connection stability. In other embodiments, the lifting plate 31 can also be fixed to the inner side of the support plate 32 and fixedly connected to both the connecting plate 33 and the support plate 32. By fixing the support plate 32 to the outer side of the lifting plate 31, the strength of the lifting plate 31 is enhanced, preventing it from collapsing unidirectionally away from the debonding basket 20 during lifting.

[0030] In one embodiment, a guide structure is formed between the connecting bracket and the support frame 10. The guide structure includes a guide rod 36 fixed on the support frame 10 and a linear bearing 37 sleeved on the guide rod 36 and fixed on the connecting bracket. The guide rod 36 is fixed to the bracket by a guide fixing seat 35, and the linear bearing 37 is fixed to the connecting bracket by a bearing seat 38. The guide rod 36 and the linear bearing 37 cooperate to provide support and stability during the operation of the lifting cylinder 34.

[0031] In one embodiment, a conical limiting block is provided at the end of the lifting shaft 21 and on the side near the degumming basket 20, and a retaining groove is formed between the two conical limiting blocks to cooperate with the lifting part 311. The width of the retaining groove is greater than the thickness of the lifting plate 31, thereby making it easier for the lifting plate 31 to be engaged in the retaining groove and reducing the difficulty of docking the two.

[0032] This application solves the problem of not being able to support diverse silicon wafers by installing a lifting assembly directly below the roller conveyor line to lift the degummed basket into place. This improves the applicability of the degummed basket. At the same time, the lifting plate and the lifting shaft on the degummed basket are connected firmly and lifted smoothly, ensuring the stability of the degummed basket transfer process.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
