Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a flipping mechanism for a mobile phone back cover bonding device. Background Technology

[0002] In the production process of modern smartphones, the back cover, as an important component of the casing, undertakes multiple tasks such as protecting internal components, enhancing the appearance design, and providing signal functions. With the continuous advancement of smartphone technology, the design of back covers has gradually become more diversified, using different materials (such as glass, metal, plastic, etc.) and continuously improving their aesthetics and durability to meet consumers' dual needs for appearance and performance.

[0003] The existing manufacturing process for mobile phone back covers typically involves multiple stages, with the bonding and pressing process being one of the key steps. To ensure the bonding quality of the back cover, the A-side and B-side of the back cover usually need to be processed separately. Specifically, the A-side of the back cover usually undergoes surface treatment first, such as spraying, printing, or coating, while the B-side requires more refined processing and assembly. During the bonding and pressing process, the B-side needs to face the pressing device, while the A-side is in contact with other components. Therefore, before the bonding and pressing process begins, the back cover must be flipped from the A-side to the B-side to complete the pressing step.

[0004] However, in existing technologies, this flipping process typically relies on manual operation. Workers need to manually flip the phone's back cover from side A to side B and accurately place it on the corresponding workbench or equipment for further processing. This flipping method has significant shortcomings in actual processing. First, manual flipping is inefficient, especially in large-scale production. Frequent flipping operations can limit the overall speed of the production line, thus affecting the production cycle. Second, prolonged reliance on manual flipping is prone to operational errors, especially since phone back covers are usually thin and have smooth surfaces. Misoperations such as tilting, slipping, or incomplete flipping can occur during manual flipping, leading to decreased production quality and further impacting production efficiency.

[0005] In view of this, the inventor conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

With the length of the frame 10 as the left-right direction, a placement station 20 for placing mobile phone back covers is erected on the top surface of the frame 10. A moving space 21 is provided in the middle of the placement station 20. A sliding mechanism arranged horizontally in the front-back direction is provided below the moving space 21. A conveying unit that can move back and forth and convey mobile phone back covers (not shown in the figure) from the loading station to the placement station 20 is erected on the top surface of the sliding mechanism. A side of the placement station 20 is equipped with a... A stand 11 is provided with a vertically arranged linear drive unit 50 fixed on the side of the stand 11 facing the placement station. The output end of the linear drive unit 50 is fixedly connected to a clamping unit 60 for opening or closing. The clamping unit 60 is symmetrically provided with clamping units 70 for clamping or putting down the back cover of the mobile phone on the opposite side. Each clamping unit 70 is also connected to a power input unit and a drive component for driving the clamping unit 70 to rotate by being connected to the power input unit. In this embodiment, the power input unit is a driven synchronous pulley 71.

[0029] In application, the sliding mechanism can drive the conveying unit to move back and forth to send the phone back cover into the placement station 20. Then, the linear drive unit 50 drives the clamping unit 60 and the clamping unit 70 to work together to accurately clamp and fix the phone back cover. Then, the drive component drives the clamping unit 60 to complete the flipping operation. The entire flipping process is fully automated and requires no manual intervention, which significantly improves production efficiency and effectively reduces the risk of human error.
