Description

Lifting device and lifting connection device Technical Field The utility model relates to the technical field of mechanical transmission, in particular to a lifting device and a lifting connection device. Background In the production process of perovskite solar cells, the vertical lifting connection of a glass substrate is one of the core process links, and the accuracy and stability of the vertical lifting connection directly determine the butt joint effect among all process line bodies, so that the photoelectric conversion efficiency and the yield of the cells are affected. However, the traditional lifting technology is easy to cause dislocation in the process of equipment butt joint due to insufficient precision, and seriously affects the process stability, and in addition, the traditional perovskite glass substrate jacking device and lifting connection technology still face obvious technical bottlenecks of poor synchronism, high maintenance cost and the like. The existing lifting connection device is mostly dependent on pneumatic driving or chain/belt transmission to realize vertical displacement, and the inherent defects are as follows: Pneumatic driving (1) has low precision. Under the influence of pneumatic fluctuation, the lifting repeated positioning precision is only +/-0.5 mm, so that accumulated errors are generated when the substrate is transferred by multiple equipment such as vapor deposition/encapsulation, and film defects or edge damages are caused. And (2) high energy consumption and maintenance cost. The pressure of the cylinder needs to be maintained continuously, the energy consumption is more than 30% higher than that of an electric system, and the sealing element is easy to age to cause air leakage and needs to be replaced frequently. The chain/belt drive (1) has poor synchronicity. The multiple groups of transmission units cause inclination of the lifting platform due to chain pitch errors or uneven stretching of the belt, and the base plate is blocked or falls off when serious. (2) mechanical wear is severe. Chain hinge or chain the tooth surface of the belt is easy to wear, and the machine needs to be lubricated or replaced regularly, so that the shutdown cost is increased. However, as perovskite solar cells are developed to be large-sized and thin, higher demands are being made on the accuracy, stability and durability of the lifting connection device. In order to solve at least one of the above problems, the present utility model provides a lifting device and a lifting connection device. Disclosure of Invention The utility model aims to provide a lifting device and a lifting connection device, wherein a single driving piece is used for driving a plurality of groups of lifting assemblies through a steering assembly, so that synchronous lifting of a plurality of supporting points is ensured, and substrate inclination or clamping stagnation is avoided. The utility model adopts the following technical scheme: in one aspect, the present utility model provides a lifting device comprising: The support structure comprises at least one support assembly, wherein the support assemblies are used for placing a substrate, each support assembly comprises a first base, a plurality of groups of support units are arranged on the first base, and the support units are connected with the substrate; The lifting structure comprises a driving piece, a steering assembly is arranged at the output end of the driving piece, the steering assembly is connected with at least one lifting assembly, rotary motion is converted into a vertical direction, and the lifting assembly is connected with the first base to drive the substrate to ascend or descend. The technical scheme has the advantages that multiple groups of supporting units are uniformly distributed on the first base, each unit independently bears the local load of the substrate, bending or stress concentration of the substrate caused by traditional single-point supporting is avoided, contact points between the supporting units and the substrate are increased, unit area pressure is reduced, and the method is particularly suitable for brittle materials (such as perovskite glass substrates) and reduces damage risks. The single driving piece drives the multiple groups of lifting assemblies through the steering assembly, so that synchronous lifting of multiple supporting points is ensured, inclination or clamping stagnation of a substrate is avoided, the steering assembly (such as a right-angle gearbox or a worm gear) converts horizontal rotation motion of the driving piece into a vertical direction, and the problem of insufficient precision caused by pressure fluctuation of a traditional pneumatic/hydraulic system is solved. In addition, the support structure of the utility model is separated from the lifting structure, and damaged parts (such as a single support unit or a ball screw) can be independently detached or replaced, so that the downtime is reduce
