[0002] When injection-molded plastic shells undergo subsequent production processing, a jig positioning device is required. Taking the jig tray in the jig positioning device as an example, the jig tray is a device used to fix, support or guide the workpiece during the manufacturing process. Its primary task is to ensure accuracy and repeatability, to ensure that each part to be processed or assembled is placed in the only correct position, to achieve rapid positioning and reduce the time for operators to adjust the position.

[0003] When positioning the jig tray in the jig positioning device for the box-shaped plastic shell, the contour correspondence method is usually used for fitting and placement, which makes it difficult to perform stable auxiliary positioning. Moreover, the jig trays mentioned above are mostly one-piece tray structures that are difficult to disassemble, making it inconvenient to replace the internal components periodically. Therefore, a jig positioning device for shell production is proposed to address the above problems. Utility Model Content
