[0059] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0060] Example 1

[0061] Please refer to Figure 1-3 A frosted laser cutting and forming device for a mobile phone rear shell includes a laser cutting and shaping mechanism 1: a laser emitting terminal 2, and a laser emitting mechanism 3:

[0062] The laser cutting shaping mechanism 1 is composed of a laser groove adjusting ruler 11, a pitch linear sliding slot 12 and a processing and fitting fixture 13;

[0063] The laser groove adjustment ruler 11 is replaceable and has two ruler models;

[0064] The edge of the laser groove adjustment ruler 11 is provided with a plurality of slots 111 for laser transparent imaging, and the slots have different grid spacings;

[0065] The slot of the pitch linear sliding slot 12 is opened on the surface of the processing and fitting fixture 13, and the pitch linear sliding slot 12 is linearly slidably arranged with the laser groove adjustment ruler 11. A precision rack 14 is also arranged on the back of the processing and fitting fixture 13. A linear rod 15 is also fitted on the edge area of ​​the precision rack 14. A linear slider 16 is installed in the middle of the linear rod 15, and a "" bracket 17 is installed between them. A fitting block 18 is vertically installed in the middle of the "" bracket 17, and an inclined connecting piece 19 is installed in the middle of the top of the fitting block 18.

[0066] A stepper motor 191 is supported in the middle of the top of the inclined connecting piece 19, and angle adjustment rollers 192 are installed on both sides of the top of the stepper motor 191. An arc-shaped bracket 193 is provided at the top of the angle adjustment roller 192, and an arc-shaped fitting gasket 194 is provided in the middle of the end of the arc-shaped bracket 193.

[0067] The output end of the stepper motor 191 is connected to a gear 1931 , and one end of the gear 1931 is linearly slidably arranged along the precision rack 14 .

[0068] By adopting the stepper motor 191 and the gear 1931, when the output end of the stepper motor 191 is driven, the rotation of the gear 1931 is adjusted, thereby achieving forward and backward displacement along the precision rack 14, and the padding end of the arc-shaped fitting gasket 194 adopted further achieves the adjustment of the position of the arc-shaped bracket 193.

[0069] When used specifically, the first step is: the laser cutting method of the mobile phone shell 67 is used as the cutting process of the back shell;

[0070] At this stage, it is necessary to ensure that the mobile phone case 67 to be processed is placed on the surface of the concave bracket 65. At this time, the user controls one end of the board surface of the lifting plate 291 to achieve fitting placement based on the area of ​​the access base 293 as the vertical support of one end of the connecting pole 292 based on the corresponding area of ​​the access base 293. The box body of the upper frequency conversion control box 27 is placed in a fit on the surface of the lifting plate 291 according to the area position of the access connection bracket 29 to share the position of the uppermost aerial lifting plate 291 to achieve shared support. At this stage, it is based on the use of one end of the box body of the frequency conversion control box 27 to support the corresponding access base 293 and one end of the rod body of the connecting pole 292 to vertically support the surface of the contacted mobile phone case 67.

[0071] When a groove shape needs to be cut out by laser, the size of each groove of the laser groove adjustment ruler 11 needs to be adjusted continuously. The specific adjustment means are:

[0072] The main control unit needs to control the output end of the stepper motor 191 to rotate. When rotating, the gear 1931 is controlled to rotate, and the gear 1931 and the precision rack 14 are fitted. According to the initial meshing rotation of the precision rack 14, the output end of the stepper motor 191 will drive the gear 1931 to rotate after power is turned on. In the meshing state between the rotations, the linear rod 15 and the processing and fitting fixture 13 area slide back and forth during this process. After the specific forward and backward sliding is completed, the position of the laser is directly projected to the slot 111.

[0073] This changes the forward and backward sliding position of the laser groove adjustment ruler 11, limiting the pattern of the laser cutting structure projected on the back of the mobile phone shell 67.

[0074] Embodiment 2:

[0075] Please refer to Figure 4 , 5 , laser emission mechanism 3:

[0076] It includes a laser emitter 31 arranged on the surface of the arc-shaped fitting gasket 194, a laser detection seat 32 is installed in the middle of the bottom end of the laser emitter 31, a focusing cover 33 is installed at the bottom of the laser detection seat 32, a fitting cover 34 is installed on the surface of the focusing cover 33, a steering seat 35 is installed on the side of the fitting cover 34, a steering motor is provided on the surface of the steering seat 35, and the output end of the steering motor is rotatably arranged with the laser detection seat 32.

[0077] By using the laser transmitter 31

[0080] By using the focusing cover 33 and the fitting cover 34, the output end of the laser emitter 31 is protected from damage during the cover connection, thus achieving the purpose of protection.

[0086] Step 2: Specific cutting:

[0087] The specific cutting is based on the clamping of the different processing fitting fixtures 13 to change the laser groove adjustment ruler 11 at will and to form an active interlaced connection between the pitch linear sliding slots 12. In this process, the front and rear sliding positions of the laser emitter 31 are adjusted according to the front and rear sliding states of the laser groove adjustment ruler 11. The initial changes and the patterns mapped on the surface of the mobile phone case 67 will also change.

[0088] In this process, the vertical support between the access base 293 support and the connecting pole 292 is used to achieve bonding with the position of the lifting plate 291. At the initial stage of bonding, the frequency conversion control box 27 that provides laser power is installed according to the position of the access connection bracket 29. Based on the box conversion state of the frequency conversion control box 27, the projected light energy power will expand the power of the laser emitter 31 from the access seat 25 to the access line tube 26, and finally be projected from each designated slot 111 position to the bottom, and finally high-intensity laser will be generated along the position of the focus cover 33, and the high-intensity laser will be transferred from the pipe position here to the surface of the laser groove adjustment ruler 11, and according to the path of the different light paths, the high-temperature laser will complete the laser mapping until it is covered on the surface of the mobile phone case 67, leaving the required pattern.
