[0002] With the development and progress of electronic technology, electronic devices have become indispensable equipment in people's daily life. During the production process of electronic devices, some shells or touch devices need to be bonded with electronic devices using adhesive backing made of PET plastic to complete the assembly of smart electronic devices. In order to ensure the stability of the touch screen structure on smart electronic devices, manufacturers pay more and more attention to the adhesive attachment step.

[0003] The existing traditional laminating process for adhesive bonding is performed purely by hand, which cannot meet the customer's requirement for adhesive positioning accuracy of ±0.3mm. The traditional pure manual laminating process is completely based on senses and experience for positioning and laminating. The consistency between the adhesive positioning and the finished product is poor and cannot meet the existing high standards of customers.

[0021] Specifically, positioning devices 200 are provided on both sides of the tooling fixture body 100 to ensure accurate positioning and stability of the workpiece during the adhesive bonding process. The fixed clamp seat 210 is symmetrically arranged and connected to the inside of the tooling fixture body 100 through the thread of the bolt 211, which can be easily disassembled. The top support of the fixed clamp seat 210 is fixedly connected with a telescopic rod 220, and the telescopic rod 220 can adjust the height of the positioning pin 230. When the adhesive material needs to be positioned, the telescopic rod 220 is extended downward to insert the positioning pin 230 into the positioning pin 110, providing a visual mark to help positioning. For some workpieces with complex shapes, the positioning pin 230 and the positioning pin 110 can be adapted to different workpiece forms through different shapes and sizes.
