Description

Technical Field

[0001] This utility model relates to the field of shaping fixture technology, specifically a mobile phone frame auxiliary shaping fixture. Background Technology

[0002] In the current mobile phone manufacturing process, the phone frame constitutes a significant portion. For this type of 3C component, especially the frame, the internal structure can become bent and deformed after multiple processes, leading to inaccuracies in the product's dimensions and reference standards. Since the product's shape is determined by positioning, tolerances exist, making accurate positioning impossible. Furthermore, previously, warped or deformed phone frames were considered defective and scrapped, resulting in high production costs for mobile phone frames. Currently, most digital hardware is manufactured through injection molding or metal stamping. However, during the metal stamping process, improper setting of some technical parameters can lead to varying degrees of deformation in the stamped product, such as dents or bulges. This requires further shaping and correction. However, this method has many drawbacks. For example, the shaping quality relies entirely on the worker's experience, resulting in inconsistent quality and difficulty in controlling product quality. Furthermore, for products with high surface quality requirements, manual work can easily leave marks on the product surface, causing product scrap. In addition, manual shaping is inefficient and labor-intensive for workers. At the same time, the increase in labor costs brings huge cost pressure to the product manufacturing process.

The lower part adopts a combination structure of pad 22 and suction cup. This upper-pressing, lower-fixing structure ensures the product is in a compacted state. The braking cylinders 3 on both sides are connected to micrometers. The value on the micrometer can be adjusted by rotating it. Based on the defect values ​​of the phone frame re-measured on the production line, the micrometer can be directly rotated to the corresponding position and locked with fixing screws 27. The micrometer is adjusted to the corresponding value and self-locks, meaning the braking cylinder 3 can only be pushed to the corresponding position and will not advance further. Place the phone frame in position. Then, press the control button 8 on the base 6. The two braking cylinders 3 will be activated simultaneously, and the controller 9 on the base 6 will display the values ​​synchronously. Once the predetermined value is reached, the forward movement will stop, thus pushing the product frame to achieve the required shaping effect for measurement. At this point, press the reset button. The positioning cylinder 24 and braking cylinder 3 will return to their positions, and the pressing block 4 will move upward, removing the phone frame. The operation is complete.
