[0002] Thin-walled flat parts are needed in semiconductor equipment. The processing of thin-walled flat parts often faces problems such as difficult clamping and easy deformation. Although vacuum suction cup fixtures have been used, they generally have defects such as poor sealing and inconvenient operation, which limits their application in high-precision processing.

[0003] For example, Chinese invention patent CN106584497A discloses a thin-sheet material taking manipulator seamless combined vacuum suction cup, wherein the suction cup bottom plate is provided with a plurality of second through holes from top to bottom, and the suction cup top plate is provided with at least one first through hole from top to bottom, and a sealing silicone ring is provided between the lower surface of the suction cup top plate and the upper surface of the suction cup bottom plate to form a closed space to suck the thin sheet. The above design can effectively distribute the air flow during vacuuming evenly on each small hole, so that the air flow of each small hole is almost similar. In actual operation, it is necessary to process a plurality of small holes, and the holes are drilled through the suction cup, and the drilling difficulty is relatively large. Although the thin sheet can be sucked for material taking during suction, when applied to processing, the suction force formed by the plurality of small holes is relatively small due to the certain impact force of the processing, and the thin-walled flat plate is easy to fall off. Moreover, the sealing silicone ring adopts a conventional structure, and the sealing performance is average. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the invention

[0029] See also Figure 1-Figure 4, an embodiment of the present utility model provides an improved aluminum vacuum suction cup fixture device, including a suction cup body 1. An exhaust groove 2 communicating in a crisscross manner is arranged on the upper surface of the suction cup body 1. An air suction hole 101 is arranged on the upper surface of the suction cup body 1. An air outlet hole 102 is arranged on one side of the suction cup body 1. A sealing groove 3 is arranged along the outer edge of the suction cup body 1 on the upper side of the suction cup body 1. The air suction hole 101 is respectively communicated with the exhaust groove 2 and the air outlet hole 102.

[0030] Vacuum is sucked from the air outlet hole 102, and the gas discharged from the exhaust groove 2 enters the air outlet hole 102 through the air suction hole 101. The crisscross exhaust groove 2 is used for exhausting gas, without the need to drill through the suction cup, which can better hold the thin-walled flat plate 5, so that the processing stability of the thin-walled flat plate 5 is better.

[0031] As Figure 1-Figure 4 shown, the exhaust groove 2 includes a plurality of laterally arranged grooves 201 arranged linearly and evenly, and a plurality of longitudinally arranged grooves 202 arranged linearly and evenly. The laterally arranged grooves 201 and the longitudinally arranged grooves 202 intersect, which can better adsorb the thin-walled flat plate 5, and the thin-walled flat plate 5 is not easy to fall off, ensuring rapid and uniform discharge of air, accelerating the vacuum establishment process, and improving the adsorption efficiency.

[0032] As Figure 1-Figure 4 shown, the sealing groove 3 includes a symmetrically arranged first straight section 301 and a second straight section 302.

[0034] As Figure 1-Figure 4 shown, the shape of the first curved section 307 is a C shape. Adopting a special-shaped structure, the sealing performance is better after the sealing groove 3 is embedded with a sealing ring.

[0035] As Figure 1-Figure 4As shown, the second curved section 308 is in an arched shape and adopts a special-shaped structure. After the sealing groove 3 is embedded with a sealing ring, the sealing performance is better.

[0036] like Figure 1-Figure 4 As shown, a plurality of pressing grooves 103 are respectively arranged on both sides of the length direction of the suction cup body 1. The suction cup body 1 is rectangular.
