Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser marking equipment technology, and in particular to a novel laser marking device. Background Technology
[0002] Laser marking uses a high-energy-density laser to locally irradiate a workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thus leaving a permanent mark. This technology can mark various texts, symbols, and patterns, with character sizes ranging from millimeters to micrometers, and is of particular significance for product anti-counterfeiting.
[0003] Some laser marking machines use conveyors to transport materials during the marking process, thereby improving the efficiency of laser marking. However, when marking materials using a conveyor, the conveyor needs to stop running. When the conveyor starts, the material will remain stationary due to inertia. When the conveyor suddenly accelerates, the material will shift backward relative to the conveyor. Similarly, when the conveyor stops, the material will continue to move forward due to inertia until the inertial force completely disappears. This inertial force will affect the stability of the material on the conveyor, causing the material to shift on the conveyor, which in turn will affect the accuracy of laser marking. Utility Model Content
[0004] The purpose of this invention is to provide a novel laser marking device that can effectively solve the problems in the background art.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figures 1-6As shown, this utility model provides a novel laser marking device, including a main unit housing 1, a protective cover 2 fixedly installed on the main unit housing 1, two protective doors 3 movably installed on the front side of the protective cover 2, a laser marking mechanism 4 installed on the main unit housing 1 inside the protective cover 2, a material conveyor 5 installed on the main unit housing 1 in front of the laser marking mechanism 4, and the laser marking mechanism 4 and the material conveyor 5 electrically connected to the main unit housing 1 via connecting lines, respectively. Two guide rods 6 are fixedly installed inside the material conveyor 5, and multiple material positioning mechanisms 7 are provided on the conveyor belt of the material conveyor 5. The material positioning mechanism 7 includes a support 8, the support 8... The material retention trough 9 is provided inside. Push plates 10 are movably installed on both sides of the material retention trough 9. A fixed seat 11 is fixedly installed in the middle of one side of the push plate 10. A push rod 12 is fixedly installed at the lower end of the fixed seat 11. A shaft 13 is fixedly installed at the lower end of the push rod 12 away from the fixed seat 11. The push plate 10 is movably installed in the material retention trough 9 through the fixed seat 11 and the push rod 12. A clamping plate 14 is provided on one side of the push plate 10. Two metal support plates 16 are movably connected between the push plate 10 and the clamping plate 14. Connecting seats 20 are fixedly installed on both sides of the support seat 8. The lower end of the connecting seat 20 is fixedly installed on the corresponding conveyor belt in the material conveyor 5.
[0027] like Figures 4-5 As shown, a first chute 17 is provided at the bottom of the material retention trough 9. Two second chute 19s are provided at the bottom of the material retention trough 9 on both sides of the first chute 17. The first chute 17 and the second chute 19 allow the push plate 10 and the clamping plate 14 to move horizontally and stably within the material retention trough 9. Guide shafts 18 are fixedly connected to both sides of the first chute 17, and compression springs are fitted on the outside of the guide shafts 18.
[0028] like Figures 3-6As shown, sliders 21 are fixedly installed on the push plates 10 located on both sides of the push rod 12. A sliding hole 22 is opened in the push rod 12. A limit ring 23 is fixedly installed on the outer side of the shaft 13 near the push rod 12. Multiple balls are rotatably installed on the limit ring 23. The push rod 12 is slidably connected to one side of the first slide groove 17, and the sliding hole 22 passes through the guide shaft 18. The lower end of the slider 21 slides in the corresponding second slide groove 19. With the help of the push rod 12, slider 21, and limit ring 23, the push plate 10 can prevent the push rod 12 from moving or shifting in the first slide groove 17. A roller 15 is rotatably installed on the outer side of the shaft 13. The roller 15 on the outer side of the shaft 13 can cooperate with The guide rod 6 inside the material conveyor 5 moves the push rod 12, which in turn moves the clamping plate 14 in conjunction with the fixed seat 11 and the metal support plate 16, thereby clamping the material. A slide rod 25 is fixedly installed on the side of the metal support plate 16 away from the push plate 10. Multiple rubber blocks 26 are fixedly installed on one side of the clamping plate 14. Two limiting grooves 24 are opened on the side of the clamping plate 14 opposite to the rubber blocks 26, and the clamping plate 14 is slidably connected to the two slide rods 25 through the two limiting grooves 24. With the bendable and deformable metal support plate 16, multiple rubber blocks 26 on one side of the clamping plate 14 can be used to clamp materials of different sizes when they abut against the outside of the material.
[0029] It should be noted that this utility model is a novel laser marking device. When laser marking materials, the materials can be placed into the material retention trough 9 located outside the main unit 1 by a mechanical gripper. This allows the material conveyor 5 to transport the support 8 downwards towards the laser marking mechanism 4 via the cooperation of two connecting seats 20. When the material conveyor 5 moves the support 8, the two rollers 15 located below the support 8 respectively abut against one side of the corresponding guide rod 6. Thus, with the help of the guide rod 6, the rollers 15 drive the shaft 13 to move to one side. Two rollers 15 located below the support 8 move relative to each other. The rollers 15, via the shaft 13, push rod 12, and fixed seat 11, drive the push plate 10 to move to one side within the material retention trough 9. This causes the sliding hole 22 in the push rod 12 to slide on the guide shaft 18, compressing the compression spring on the outside of the guide shaft 18. Simultaneously, the push plate 10, via two metal support plates 16, drives the clamping plate 14 to move to one side. The two clamping plates 14 then automatically clamp the material placed in the material retention trough 9. Furthermore, the movement of the push plate 10 driven by the rollers 15 is constant. When clamping and fixing materials of different sizes, multiple rubber blocks 26 on one side of the clamping plate 14 abut against the outside of the material, and the push plate 10 continues to push the two metal support plates 16 towards the clamping plate 14. This causes the sliding rods 25 on one side of the two metal support plates 16 to slide in the corresponding limiting grooves 24, thereby using the bent metal support plates 16 to support the clamping plate 14, thus achieving the clamping and fixing of materials of different sizes. When the material conveyor 5 drives the corresponding support seat 8 to move directly below the laser emitter of the laser marking mechanism 4, the material is clamped and fixed. When the sensor on the rear side of the material conveyor 5 detects the support seat 8, the material conveyor 5 can be stopped. After the set stopping time, the material conveyor 5 can be restarted to transport the subsequent support seat 8. After the material is laser marked, the support seat 8 drives the two rollers 15 below to move to the other side of the guide rod 6. With the help of the elastic force of the compression spring on the outside of the guide shaft 18, the two push rods 12 are pushed into the first slide groove 17 respectively, so that the two sets of push plates 10 and clamping plates 14 can be reset and moved, so that the material can be unloaded by the unloading mechanical claw.
