Description

Technical Field

[0001] The utility model relates to the technical field of marking devices, in particular to a laser marking device for an iron ring of a mobile phone camera. Background Art

[0002] The metal ring (or protective ring) of a mobile phone camera inherits the traditional style of cameras and usually labels key parameters such as aperture size and pixel count. The purpose of these labels is to provide users with an intuitive understanding of the performance and characteristics of the mobile phone camera. For example, the aperture size label can let users know the amount of light entering the camera in a specific environment, thus affecting the effect of night scene shooting; the pixel number label can let users understand the camera's ability to capture details, which in turn affects the clarity of the photo.

[0003] Since the iron ring of the mobile phone camera is very small, if marking is required, it is necessary to use a jig to clamp it and then perform the marking operation. For example, Chinese utility model CN215615885U discloses a laser fixing jig for the metal protective ring of a mobile phone camera. By moving two fixed blocks toward each other, the protective ring can be clamped. However, during actual production operations, the inventor found that since the iron ring of the mobile phone camera is very small, it is necessary to manually load it one by one to the fixing jig for clamping. The loading operation is very cumbersome, which seriously affects the efficiency of the marking operation and results in low overall production efficiency of the iron ring. Moreover, since it needs to be clamped by a fixed jig, once excessive force is applied, the iron ring is easily damaged, which seriously limits the production yield of the iron ring.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0054] Please also refer to Figures 1 to 5The laser marking device for a mobile phone camera iron ring provided in an embodiment of the present application is now described. The laser marking device for a mobile phone camera iron ring includes: a frame 10, a laser marking module 11, a CCD module 12, and a fixing fixture 13.

[0055] The frame 10 is provided with a first support frame 101, which is installed on the top of the frame 10 and extends upward. The laser marking module 11 and the CCD module 12 are installed on the first support frame 101, and the laser marking module 11 and the CCD module 12 are arranged at a left-right distance. The CCD module 12 is used to locate the iron ring of the mobile phone camera, and the laser marking module 11 is used to perform laser marking on the iron ring of the mobile phone camera that has been located. The laser marking device also includes a first execution device 14 and a second execution device 15. The first execution device 14 is used to locate the iron ring of the mobile phone camera. The device 14 is used to drive the fixed fixture 13 to move along the X-axis direction, and the second actuator 15 is used to drive the fixed fixture 13 to move along the Y-axis direction; the fixed fixture 13 is installed on the second actuator 15 and is located below the laser marking module 11 and the CCD module 12. A first concave cavity 131 is provided on the top of the fixed fixture 13, and a plurality of support columns 132 are detachably installed in the first concave cavity 131. A first positioning protrusion 1321 is provided on the top of each support column 132, and the first positioning protrusion 1321 is used to be inserted into the through hole 21 of the iron ring.

[0056] During operation, the iron ring is loaded onto the support column 132 and the first positioning protrusion 1321 is inserted into the through hole 21 of the iron ring to complete the positioning of the iron ring. After loading the iron rings one by one onto the support columns 132, the entire fixture 13 is loaded onto the laser marking device to continuously mark multiple iron rings. Specifically, the support column 132 and the first positioning protrusion 1321 can complete the support and positioning of the iron ring, eliminating the need for clamping to fix the iron ring, avoiding the problem of iron ring damage, and thus improving the production yield of the iron ring.
