Its main function is to ensure the precise positioning and stable fixation of the PCB during the printing process, thereby ensuring printing quality and production efficiency.

[0003] When using an existing printing vacuum positioning jig, a sheet with a PCB unit is usually placed on the jig surface, and the position of the sheet can be fixed by vacuum adsorption. However, when vacuum adsorption is performed on the sheet, there is no positioning structure between the sheet and the jig, and it is easily moved by external force. The staff needs to readjust the sheet before vacuum adsorption can be performed, which is inconvenient to operate and time-consuming.

[0004] Therefore, we proposed a printed vacuum positioning fixture to solve the above problems. Utility Model Content
