To sum up, the swing arm structure formed by the swing plate used in the present invention has high strength and is not easy to deform or shake. There is a strip-type installation hole directly on the swing plate for installing the vacuum nozzle, which saves the technical feature of the rotating block, which is not only low in cost, but also easy to install and maintain. Four rack and pinion groups are adopted, and the up-and-down movement of the lifting slide seat (or called the lifting platform) relative to the lifting fixed seat is changed into a 180-degree reciprocating swing of the swing arm. The purchase cost of the servo motor is reduced. It is easy to realize the integrated control of swing and lift.

The above only uses examples to further illustrate the technical content of the present invention, so that readers can understand more easily, but it does not mean that the implementation of the present invention is limited to this, and any technical extension or re-creation done according to the present invention is subject to the present invention. protection of. The protection scope of the present invention shall be determined by the claims.
