[0068] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present application, and are not used to limit the present application.

The slide rail of the marking moving module 11 extends along the X direction, and the laser marking unit 16 is used for marking the workpiece and is arranged on the slider of the marking moving module 11. The marking moving module 11 can drive the laser marking unit 16 to move along the X direction. A plurality of carrier modules 12 are located below the marking moving module 11, and the slide rails of the plurality of carrier modules 12 respectively extend along the Y direction and are arranged side by side along the X direction. A carrier unit 15 for carrying the workpiece is respectively arranged on the slider of each carrier module 12, and the carrier module 12 can drive the carrier unit 15 to move along the Y direction. Among them, the X direction is perpendicular to the Y direction.

[0070] Since the laser coding device is provided with a plurality of carrier modules 12 and a coding moving module 11, and a laser coding unit 16 is arranged on the coding moving module 11, the laser coding unit 16 can be driven by the coding moving module 11 to move above any one of the carrier modules 12. In this way, a single-head multi-station structural mode of the laser coding device is realized, that is, a plurality of stations share a single laser coding unit 16, which is beneficial to improving the processing efficiency of the equipment, reducing the cost of the equipment and facilitating large-scale production. Moreover, the slide rail of the coding moving module 11 extends along the X direction and can drive the laser coding unit 16 to move along the X direction, and the slide rail of the carrier module 12 extends along the Y direction and can drive the carrier unit 15 to move along the Y direction. Since the slide rails of the coding moving module 11 and the carrier module 12 are both straight lines, the stability of the equipment can be higher, the accuracy is easier to control, and the reliability is better.

[0071] In some specific embodiments, the laser coding device further includes a detection moving module 13 and a workpiece detection unit 17, and the workpiece detection unit 17 is used to detect whether the workpiece meets the corresponding quality requirements. The slide rail of the detection moving module 13 extends along the X direction and is arranged side by side with the coding moving module 11 along the Y direction. The workpiece detection unit 17 is arranged on the slider of the detection moving module 13, and the workpiece detection unit 17 can be driven by the detection moving module 13 to move along the X direction to above any one of the carrier modules 12. In this way, the three axes complete visual positioning and dirt detection at any position on the workpiece through orthogonal movement in cooperation with each other, further realizing the single-head multi-station structural mode of the laser coding device, that is, a plurality of stations share a single workpiece detection unit 17. Similarly, it is not only beneficial to improve the processing efficiency of the equipment, but also beneficial to reducing the cost of the equipment and facilitating large-scale production.

[0072] Among them, the carrier module 12, the coding moving module 11 and the detection moving module 13 can adopt linear motor modules, and the number of the carrier modules 12 can be set to 2, 3, 4 or more according to actual production needs.

As Figure 6 shown, the loading and unloading conveyor 2 includes a plurality of conveying rollers 21. The plurality of conveying rollers 21 are arranged at intervals along the length direction of the conveyor line. Coarse positioning rollers 22 are respectively arranged at both ends of the conveying rollers 21 along the width direction of the conveyor line. As Figure 3As shown in the figure, the loading and unloading manipulator 3 is hoisted above the loading and unloading conveyor line 2 through a mounting frame. The loading and unloading conveyor line 2 is a four-axis manipulator, and a suction cup mechanism for fixing workpieces is provided at the material taking end.

[0081] Furthermore, the laser coding device further includes a lifting and limiting unit arranged below the loading and unloading conveyor line 2.

[0084] In some specific embodiments, since some workpieces need to be flipped for coding, the laser coding device further includes a flipping unit. As Figure 1 and Figure 8 shown, the flipping unit is arranged between the loading and unloading conveyor line 2 and the carrier module 12 and includes an adsorption seat body 51 and a flipping driving module 52. The flipping driving module 52 is connected to the adsorption seat body 51 and is used to drive the adsorption base 51 to flip.

Drawer slides and magnetic engaging members 63 are provided on the workbench 71, and the defective product storage drawer 61 is slidably arranged on the drawer slides. When working, the defective product storage drawer 61 is in a closed state, and the defective product storage drawer 61 is fixedly attracted to the workbench 71 by the magnetic engaging members 63; when it is necessary to take out the defective products in the defective product storage drawer 61, the defective product storage drawer 61 is pulled out from the workbench 71. The defective product carrier 62 is installed in the defective product storage drawer 61 and is used to place defective products. The defective product carrier 62 has two areas, one area is used to place workpieces with dirt defects, and the other area is used to place workpieces with code reading defects. The defective product discharging and storing unit 6 is of a drawer structure, which is convenient for taking out defective products. Among them, positioning posts are provided on the bottom plate of the defective product storage drawer 61, and positioning sleeves matched with the positioning posts are embedded on the bottom plate of the defective product carrier 62. Through the cooperation of the positioning posts and the positioning sleeves, the defective product carrier 62 can be fixed in the defective product storage drawer 61. In this way, the defective product discharging and storing unit 6 adopts a defective product separated storage bin type storage, which can realize centralized management of defective products and improve the continuous processing and production capacity of the equipment.

[0088] Optionally, as Figure 11As shown in the figure, the defective product picking module 8 includes an adsorption rack 81, a defective product flipping module 82, a defective product lifting module 83, and a defective product shifting module 84. The adsorption rack 81 is used to adsorb and fix the workpiece 9 and is arranged on the rotating arm of the defective product flipping module 82.

The defective product lifting module 83 is arranged on the slider of the defective product shifting module 84, and the defective product shifting module 84 can drive the defective product lifting module 83 to move in the Y direction to drive the workpiece 9 to move. The adsorption rack 81 includes a suction cup bracket and a vacuum suction cup arranged on the suction cup bracket. The suction cup bracket is fixed on the rotating arm through an aluminum profile fixing block. Specifically, after the adsorption rack 81 sucks the defective product, the slider of the defective product lifting module 83 rises, and further flips. The slider of the defective product shifting module 84 moves to the slot of the defective product carrier 62 and inserts the workpiece 9 into the slot according to the classification of the defective product.

[0089] It should be noted that the structures and principles of devices such as the front dust removal device 41, the back dust removal device 42, the flipping drive module 52, the lifting module 53, the horizontal shifting module 54, the defective product flipping module 82, the defective product lifting module 83, and the defective product shifting module 84 are well-known to those skilled in the art and do not belong to the core improvement part of this application, so they will not be elaborated here.

[0090] Specifically, the working process of the laser coding device of the present application is as follows: the workpiece 9 is loaded from the loading and unloading conveyor line 2, and the dust on the front surface of the workpiece is removed by the front dust removal device 41 installed above the entrance of the conveyor line during the loading process. The loading and unloading robot 3 takes the workpiece 9 from the loading and unloading conveyor line 2 and moves it above the reverse dust removal device 42 installed on the flip unit. The loading and unloading robot 3 moves back and forth above the reverse dust removal device 42 to remove the dust on the bottom surface of the workpiece. After removing the dust on the upper and lower surfaces of the workpiece 9, the loading and unloading robot 3 places the workpiece 9 on the carrier unit 15. Among them, for the workpiece 9 that needs to be turned over, after dust removal on the back side, the loading and unloading robot 3 places the workpiece 9 on the adsorption seat 51 of the flip unit. After the suction cup sucks the workpiece 9, the flip motor drives the flip axis to flip the workpiece 9 180 degrees, and the horizontal shift module 54 shifts the workpiece 9 to the top of the carrier unit 15 on the workbench 71. The lifting module 53 descends to place the workpiece 9 on the carrier unit 15 to achieve a 180-degree flip of the product. Then, after the carrier unit 15 is inspected for dirt by the workpiece detection unit 17, the dirty defective products are shifted to the defective product unloading storage unit 6 through the carrier module 12, and the good products are transported to the laser coding unit 16 for laser coding and code reading. Similarly, if the code reading is poor, it is shifted to the defective product unloading storage unit 6 through the carrier module 12, and the good products are shifted to the loading position of the loading and unloading robot 3. The good products are sucked by the loading and unloading robot 3 and put into the loading and unloading conveyor line 2, and the assembly line flows out.

[0091] To summarize, the laser coding device of the present application is equipped with a double X double Y linear motor module on a customized marble platform, which effectively enhances the high precision and continuous processing stability of the equipment; cooperates with the laser coding terminal flight optical path architecture design to achieve the continuous coding processing capability of a single laser coding terminal; the hoisting four-axis manipulator automatically loads and unloads materials, and cooperates with the roller conveyor line to connect the upstream and downstream machines to achieve fully automatic production, saving costs, space, and manpower, with a high degree of automation; with automatic clamping and positioning modules and automatic flipping modules, the equipment has high versatility and can process a wide range of products; a set of laser coding machines is used for alternating coding processing, and multiple stations are used for continuous coding, which reduces production costs and improves production efficiency; the use of separate silo storage for defective products can achieve centralized management of defective products and improve the continuous processing production capacity of the equipment.
