[0002] Laser coding is a coding method that uses high-energy-density lasers to partially irradiate the workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thereby leaving a permanent mark. Laser coding can produce a variety of text, symbols, and patterns, and the character size can range from decimeters to micrometers, which is of special significance for product anti-counterfeiting. During the laser coding process, positioning tooling is also required to position the product to ensure accurate and correct coding.

In addition, in the process of laser coding of different products, the position needs to be frequently calibrated, and it does not have the function of quickly centering the product, and the practicality of the device is low. Therefore, it is urgent to improve the existing laser coding positioning tooling and provide a laser coding positioning tooling. Utility Model Content

[0028] On the basis of the above structure, a hole-like structure is provided in the middle of the side where the two T-shaped frames 5 are close to each other, and a support spring 6 is fixedly connected to the inner side of the hole-like structure. The front and rear ends of the T-shaped frame 5 are symmetrically provided with oblique grooves 7, and the bottom of the vertical section of the T-shaped frame 5 is engaged and slidably located on the inner side of the slide groove 3.

[0029] In this embodiment, by providing the support spring 6, when the bidirectional screw rod 4 rotates, the T-shaped frame 5 and the first positioning assembly 8 can be controlled to be in a relatively static state and move synchronously.

[0030] Based on the above structure, one end of the two brackets 82 away from the clamping plate 81 is slidably mounted on the outside of the two guide rods 2, and one end of the fixing rod 83 away from the clamping plate 81 is slidably located in the hole-like structure opened in the middle of the T-shaped frame 5 and is fixedly connected to the support spring 6.

[0031] In this embodiment, the stability of the first positioning assembly 8 during the sliding adjustment process can be improved by slidingly connecting the bracket 82 and the guide rod 2 .

[0032] On the basis of the above structure, the two groups of second positioning components 9 are linked together, and the sliding directions of the two groups of second positioning components 9 are always opposite.

[0033] In this embodiment, the second positioning component 9 is provided to facilitate front-to-back center clamping and positioning of the product to be coded.

[0034] On the basis of the above structure, the second positioning assembly 9 includes a movable rod 91, a connecting column 92, a clamping block 93 and a second rubber pad 94. The movable rod 91 is slidably sleeved on the outside of the limiting rod 85. A connecting column 92 is fixed above one end of the movable rod 91 close to the T-shaped frame 5.

[0037] In this embodiment, by providing the connecting column 92, when the T-shaped frame 5 slides close to the clamping plate 81, the connecting column 92 can be squeezed by the inclined groove 7 opened on the top of the T-shaped frame 5, so that the two groups of second positioning components 9 can be controlled to slide synchronously in opposite directions.

At this time, the T-shaped frame 5 and the first positioning component 8 are in a relatively static state until the two clamping plates 81 clamp the coded product in the left and right centers. At this time, the clamping plates 81 cannot continue to move and are in a static state, and the two-way screw rod 4 is continuously controlled to rotate. At this time, the elastic force of the supporting spring 6 can be overcome, and the T-shaped frame 5 can continue to move and keep approaching the clamping plates 81. The two inclined grooves 7 opened on the top of the T-shaped frame 5 can be used to squeeze the connecting column 92, so that the two movable rods 91 can respectively drive the two clamping blocks 93 to slide in the opposite direction and approach each other, so that the product can be clamped in the front and back centers. Compared with the comparative documents, this device can quickly center and position various products of different sizes in the center of the support table 1, and then the laser coding machine 12 can be used to laser code the product;

[0042] The electric telescopic rod 11 facilitates quick adjustment of the height of the laser coding machine 12 according to the height of the product to be coded, and the guide rod 2 and the limit rod 85 can improve the sliding stability of the first positioning assembly 8 and the second positioning assembly 9. In addition, the first rubber pad 86 bonded to the outer wall of the clamping plate 81 and the second rubber pad 94 bonded to the outer wall of the clamping block 93 can avoid damage to the product surface due to excessive clamping force, and can achieve flexible clamping of the product, and the clamping is more stable.
