[0002] In the assembly process of workpiece, the position to be assembled of workpiece is usually glued, and then the corresponding spare parts are attached to the position. To ensure that the spare parts can be firmly bonded to the surface of the workpiece, prevent it from falling off during subsequent use or transportation, it is usually necessary to apply a certain pressure to the spare parts to enhance the bonding strength between them.

[0003] In the prior art, the traditional pressure application method relies on manual operation, i.e. the worker directly presses the spare parts with his hand. However, this manual pressure application method has many problems. First of all, since the hand operation needs to apply continuous force, the labor intensity of the worker is large, especially in mass production process, which is easy to cause fatigue, thereby affecting the work efficiency and quality. Secondly, the pressing force of the hand is difficult to control accurately, and it is easy to deviate due to individual differences or improper operation. When the pressing force is too large, it may cause deformation or even damage to the spare parts, thereby affecting the overall performance of the workpiece; while when the pressing force is too small, it may cause the spare parts to be not firmly bonded to the workpiece, increasing the product failure rate and reducing the assembly yield. In addition, manual operation may further affect the bonding effect due to changes in external factors (such as environmental temperature, humidity, etc.). Therefore, the utility model provides a press mechanism and an automatic press device to solve the above problems. SUMMARY

[0015] 1. Through the cooperative action of the positioning groove, the anti-skid pressing plate and the buffer, the workpiece realizes multi-level stable positioning and flexible buffering during the pressing process. The positioning groove preliminarily positions the workpiece, the anti-skid pressing plate realizes symmetrical clamping through the linkage of the rotating shaft and the moving frame, and the workpiece is ensured to have no slight displacement during pressing.
