[0010] Preferably, the outer side of the screw rod is provided with nut, and the nut is threadedly connected with screw rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The improved mechanism for the connection of the PECVD automated gantry cylinder of the heterojunction battery replaces the floating joints of the automated gantry cylinders of each section of Maiwei CVD with a new type of floating joint, so as to protect the cylinder and extend the service life of the cylinder.

[0013] 2. The improved mechanism for the gantry cylinder connector in the PECVD automation system for heterojunction cells requires the replacement of 24 gantry cylinders with floating joints on each machine. Without the floating joints, cylinders needed to be replaced on average every two months. After the floating joints were replaced, the cylinders can be used for more than a year on average. This reduces the wear and tear of 144 cylinders per machine per year, amounting to approximately RMB 144,000. Replacing a damaged cylinder with the replacement machine takes about 60 minutes, resulting in an average of 8,640 minutes of cylinder replacement time per year, impacting production capacity by 2,073,600 units, or approximately RMB 7,413,000. Therefore, it can save on hardware losses and production capacity losses annually. Attached Figure Description
