Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] The existing scheme using a vacuum pump needs a stable and reliable vacuum system due to the dependence on the vacuum source, which increases the equipment cost and maintenance complexity. Moreover, due to the high sealing requirement, high-strength application may cause poor sealing of the air slip ring and other components, thereby causing vacuum leakage and affecting the adsorption effect. The durability and system stability of the air slip ring and other components are strictly required.

[0024] Due to the working characteristics of the ring-shaped conveying device, the fixture loading platform must be circularly rotated, so it is inevitable to use an electric slip ring to power the linear motor of the fixture. The electric slip ring technology is quite mature, and the brush durability is very high. Therefore, the utility model adopts the mode of taking power from the ring-shaped conveying device to replace the traditional mode of taking air, and uses electric energy to drive the negative pressure fan to rotate to form negative pressure, thereby achieving the original adsorption effect.
