Technical Field
[0001] This utility model relates to the field of mobile phone mid-frame film application device, and in particular to a fully automatic multi-station high-precision film application device for mobile phone mid-frame. Background Technology
[0002] The mid-frame of a mobile phone refers to the outer casing, typically made of metal or plastic. Its function is to protect the internal circuit boards and components, while also enhancing the overall appearance and feel of the phone. Different manufacturers design their mid-frames differently; some have a single, continuous frame, while others have a two-part frame. Furthermore, the materials used for the mid-frame also vary, such as the strength of metal versus the lightweight nature of plastic.
[0003] Traditional jig-based film application methods rely on manual operation, which is not only slow but also requires a large amount of human resources. Due to the high dependence on manual labor, labor costs remain high, especially in mass production. Existing film application equipment usually needs to be equipped with a complex vision system to grasp the product outline, which increases the cost and maintenance difficulty of the equipment. For products with unclear outlines, these devices cannot achieve high-precision film application, resulting in unstable product quality and increased defect rate.
[0004] Therefore, it is necessary to provide a new fully automatic multi-station high-precision film application device for mobile phone mid-frames to solve the above-mentioned technical problems. Utility Model Content

The L-shaped bracket and placement plate are fixedly connected to the top of the conveying bracket, and the side wall of the L-shaped bracket is rotatably connected to a take-up roller, a loading roller, and multiple auxiliary adjustment rollers.
[0011] Furthermore, the gripping component includes a linear drive component, which is fixedly connected to the top of the conveying bracket. The linear drive component is provided with a double-sided bracket, and cylinders are fixedly connected to both ends of the double-sided bracket.

The robotic arm 7 is a collaborative robot arm of model UR5e, which has the characteristics of high precision and high flexibility and is suitable for a variety of complex tasks.

[0027] The turnover mechanism includes a turnover base 11, a drive motor is fixedly connected inside the turnover base 11, a turnover disk 12 is fixedly connected to the output end of the drive motor, and multiple turnover fixtures 13 are equidistantly installed on the top of the turnover disk 12 along its axial direction.

[0028] The film application mechanism includes a conveyor bracket 14. A carrier belt conveyor assembly, a gripping assembly, and a product straightening assembly are fixedly connected to the top of the conveyor bracket 14. The carrier belt conveyor assembly includes an L-shaped bracket 15 and a placement plate 16, which are fixedly connected to the top of the conveyor bracket 14. A take-up roller 17, a loading roller 18, and multiple auxiliary adjusting rollers 19 are rotatably connected to the side wall of the L-shaped bracket 15. The take-up roller 17 and the loading roller 18 are driven by motors. The loading roller 18 rotates and unfolds the carrier belt with auxiliary materials, while the take-up roller 17 winds up the carrier belt after the auxiliary materials have been removed. The gripping assembly includes a linear drive component 20, which is fixedly connected to... At the top of the conveying bracket 14, a double-sided bracket 21 is provided on the linear drive component 20. Cylinders 22 are fixedly connected to both ends of the double-sided bracket 21. Suction cup 3 23 and suction cup 4 24 are fixedly connected to the output ends of the two cylinders 22 respectively. Suction cup 3 23 is used to pick up the product on the turnover fixture 13 and move it into the product correction component.

[0033] The working principle of this utility model is as follows: In specific implementation, a PVC box 6 containing the product is placed between multiple limiting posts 5 on the top of the PRC control box 4. A carrier tape with auxiliary materials is installed on the loading roller 18 and sequentially wound around multiple auxiliary adjusting rollers 19, a placement plate 16, and a take-up roller 17 to achieve the winding and feeding of the carrier tape. The main control panel 2 is activated to start the robotic arm 7, and the product is taken out of the PVC box 6 by suction cup 2 10 and placed into the turnover fixture 13. After all the products in the PVC box 6 have been taken out, the PVC box 6 is removed by suction cup 1 9 to continue processing the products at the bottom. The drive motor of the turnover mechanism drives the turnover disk 12 to rotate, and the products on the turnover fixture 13 are sequentially transferred to each workstation. In the film application mechanism, the gripping component passes through a straight line... Driven by a motor, suction cup 3 23 moves the product from the turnover fixture 13 to the product correction component. The product correction component corrects the product's placement position through multiple pushers 26 to ensure film application accuracy. At the same time, suction cup 4 24 picks up the auxiliary material from the placement plate 16 and accurately attaches it to the product through a linear motor, completing the film application operation. The film-applied product is sent back to the turnover fixture 13 by suction cup 4 24 and continues to flow to the production line 27. Electric cylinder 2 30 on the production line 27 drives suction cup 5 31 to pick up the product from the bottom and move it to the top. Positioning brackets 32 on both sides of suction cup 5 31 restrict the angle of the product, causing the product to detach from the turnover fixture 13. Then, electric cylinder 1 29 drives the product to be conveyed onto the production line 27 and detaches the product from the production line 27, allowing it to enter the next process.
