[0002] Currently in the field of solar cell module laminating machines, vacuum equipment pipelines are connected to vacuum pumps using hard pipes or hoses with flanges to evacuate the solar cell laminating machine equipment. Since the equipment always needs vacuum equipment to maintain vacuum conditions during the lamination process, the existing vacuum equipment structure cannot maintain or replace the vacuum pump while the equipment is running. When the vacuum pump is damaged, the entire line of equipment needs to be shut down to replace the vacuum pump group, resulting in a decrease in the equipment's utilization rate.

[0003] Therefore, there is an urgent need for a vacuum pump unit that can work continuously and can be repaired without affecting the work progress. Utility Model Content

When a secondary vacuum pump needs maintenance or replacement, by closing the valve and cutting off the connection between the secondary vacuum pump and the connecting tube, maintenance or replacement can be carried out without stopping the work of other secondary vacuum pumps, thereby improving efficiency.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.
