[0002] A metal cover for a mobile phone camera lens is a metal protective component that covers the outside of the camera lens of a mobile phone. It can firmly fix multiple camera lenses, flash and other components on the back of the phone to prevent them from becoming loose or shifting. It also enhances the aesthetics and brand recognition.

[0003] Some mobile phone lens metal cover plates require the riveting of copper pillar components onto their inner surface. These copper pillar components serve multiple functions, including assisting in the assembly and positioning of the metal cover plate and acting as conductors for electrical connection with related components. During installation, positioning holes are typically pre-machined on the inner surface of the metal cover plate. Then, a precision riveting process is used to forcefully press one end of the copper pillar component into the positioning hole to achieve an interference fit, thus fixing the copper pillar component to the metal cover plate. If the copper pillar component and the metal cover plate are installed manually using riveting, it is difficult to guarantee installation accuracy, and the installation efficiency is low. Therefore, there is an urgent need to provide a copper pillar riveting device for mobile phone lens cover plates. Utility Model Content

[0024] like Figures 2-10 As shown in the embodiment of this application, the copper column riveting equipment for mobile phone lens cover plates includes a workbench 1, and an electric turntable 2, a copper column feeding device 3, a copper column loading device 4, a copper column riveting device 5, a cover plate handling device 6, a belt conveyor 7, and a lens cover plate unloading device 8 are installed on the top of the workbench 1.

[0025] The electric turntable 2 has four stations arranged at 90-degree intervals along its top circumference: a first station 221, a second station 222, a third station 223, and a fourth station 224. Each station 221, 222, 223, and 224 is equipped with a positioning fixture 9. Each positioning fixture 9 has at least two positioning slots 91 for placing the lens cover plate product 80. A positioning fixture is provided within each positioning slot 91, and the fixture has a locking protrusion structure that matches the corresponding hole on the lens cover plate product 80, thus enabling the lens cover plate product 80 to be positioned within the positioning slot 91. A cover plate 10 is fitted over the top of the positioning fixture 9, and the cover plate 10 has a conical positioning through hole 101 corresponding to the positioning hole 801 of the lens cover plate product 80. A copper column feeding device 3 is located outside the second station 222 and is used for automatic feeding of copper columns. The column feeding device 4 is located above the copper column feeding device 3 and the second station 222. It is used to feed the copper column to the conical positioning through hole 101 of the second station 222. The copper column riveting device 5 is located above the third station 223. The copper column riveting device 5 includes a riveting punch 54 that matches the conical positioning through hole 101. It is used to press the copper column in the conical positioning through hole 101 into the positioning hole 801 of the lens cover plate product 80. The cover plate transport device 6 is located above the second station 222 and the fourth station 224. It is used to transport the cover plate 10 of the fourth station 224 to the top of the positioning fixture 9 of the second station 222. The belt conveyor 7 is located outside the fourth station 224. It is used to transport the lens cover plate product 80. The lens cover plate unloading device 8 is located above the belt conveyor 7 and the fourth station 224. It is used to unload the riveted lens cover plate product 80 onto the belt conveyor 7. Optionally, a fiber optic sensor can be installed below the positioning fixture 9 at the first station 221 on the top of the worktable 1. The electric turntable 2 and the positioning fixture 9 have through holes for the fiber optic sensor's light to pass through. When the copper column riveting equipment is working, the light emitted by the fiber optic sensor is used to detect whether a lens cover plate product 80 is placed on the positioning fixture 9. Alternatively, a set of fiber optic sensors can be installed on one side of the positioning fixture 9 at the second station 222, third station 223, and fourth station 224 on the top of the worktable 1, aligned with the position where the cover plate 10 should appear. When the electric turntable 2 rotates into position... When the fiber optic sensor detects that a cover plate 10 is placed on the positioning fixture 9 at the second station 222, the fiber optic sensor transmits a signal to the control system of the copper column riveting equipment. The copper column feeding device 4 can be controlled by the PLC. Similarly, when the fiber optic sensor detects that a cover plate 10 is placed on the positioning fixture 9 at the third station 223, the copper column riveting device 5 can be controlled by the PLC. When the fiber optic sensor detects that a cover plate 10 is placed on the positioning fixture 9 at the fourth station 224, the cover plate conveying device 6 and the lens cover plate unloading device 8 can be controlled by the PLC to work sequentially.

[0026] Specifically, the electric turntable 2 includes a cam indexer 21 and a turntable 22. The turntable 22 is horizontally mounted on the output shaft of the cam indexer 21. The cam indexer 21 converts continuous rotational motion into intermittent rotational motion, thereby driving the turntable 22 to rotate intermittently by a specified angle. In this embodiment, the cam indexer 21 stops once every 90 degrees counterclockwise. The cam indexer 21 is electrically connected to the control system of the copper column riveting equipment. The intermittent rotation angle of the cam indexer 21 can be set by the PLC program to control the start and stop of the cam indexer 21. The structure of the cam indexer 21 is existing technology and will not be described in detail here.

[0027] Each of the four corners of the turntable 22 is vertically mounted with a first linear bearing 20; each of the four corners of the bottom of the positioning fixture 9 is vertically fixedly connected with a first guide shaft 30, the lower end of the first guide shaft 30 passes through the first linear bearing 20 and is fixedly connected with a limit plate 301, a buffer spring 302 is sleeved on the first guide shaft 30, one end of the buffer spring 302 abuts against the bottom of the positioning fixture 9 and the other end abuts against the top of the first linear bearing 20, and a top post 40 is vertically fixedly connected to the center of the bottom of each positioning fixture 9; a limit post 50 is vertically fixedly connected to the top of the worktable 1 below the positioning fixture 9 of the third station 223, and the limit post 50 is used to limit the bottom of the top post 40. When the riveting punch 54 presses down, the positioning fixture 9 is subjected to downward pressure. At this time, the buffer spring 302 is gradually compressed. During the downward movement of the positioning fixture 9, the buffer spring 302 provides buffer for the positioning fixture 9, avoiding a hard impact between the riveting punch 54 and the lens cover plate product 80, until the bottom of the positioning fixture 9, the top post 40, contacts the limiting post 50, and the positioning fixture 9 stops moving downward. Conversely, when the riveting punch 54 moves upward, the buffer spring 302 extends due to the elastic force, driving the positioning fixture 9 to move upward and reset. The limiting plate 301 at the lower end of the first guide shaft 30 abuts against the bottom of the first linear bearing 20, thereby limiting the positioning fixture 9.

[0028] The copper column feeding device 3 includes a vibratory feeder 31, a linear vibratory feeder 32, and a receiving mechanism 33.

The abutting end of the receiving fixture 332 is provided with a receiving slot 3321 that matches the copper column. The slide cylinder 331 is used to drive the receiving fixture 332 to move left and right along the X-axis. When the receiving slot 3321 is aligned with the discharge port of the linear vibration track 321, it is used to receive the material. The copper column part 90 can enter the receiving slot 3321. Optionally, an optical fiber sensor is installed on the receiving fixture 332. The optical fiber sensor is used to detect whether there is a copper column part 90 in the receiving slot 3321, thereby transmitting a signal to the control system of the copper column riveting equipment. The slide cylinder 331 can be controlled by a PLC to operate.
