Description

Technical Field

[0001] The utility model relates to the field of laser marking machines, in particular to a laser marking machine for the production of electronic components. Background Art

[0002] Laser marking machines use laser beams to permanently mark the surfaces of various materials. Marking creates intricate designs, trademarks, and text by evaporating surface materials and revealing underlying materials. Laser marking machines are primarily categorized as CO2 lasers, semiconductor lasers, fiber lasers, and YAG lasers. Laser marking machines are primarily used in applications requiring greater precision and accuracy, including electronic components, integrated circuits (ICs), electrical appliances, mobile phones, hardware, tool accessories, precision instruments, eyewear and watches, jewelry, automotive parts, plastic buttons, building materials, and PVC pipes.

[0003] In the prior art, during the production and processing of electronic components such as circuit boards, in order to meet the needs of different identification in the production of circuit boards, laser marking machines are often used to engrave logos including model, specifications, production date, serial number, barcode, QR code and company logos on the circuit boards. In order to prevent displacement during the marking process of the circuit boards and affect the marking effect, a clamp is usually used before marking on the circuit boards to position and fix the circuit boards. However, the clamps currently used in laser marking machines are generally fixed, and the sizes of circuit boards of different models are different, resulting in the inability to quickly adjust, position and fix circuit boards of different sizes. Workers need to manually debug the clamps or replace the corresponding clamps, which is cumbersome to operate, thereby not only reducing the applicability of the clamps, but also reducing work efficiency.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 2 As shown, a set of bilaterally symmetrical sliding openings 9 are provided on the inner bottom surface of the concave seat 8, and rotation holes 10 are respectively provided on the front and rear side walls of the inner portion of the concave seat 8. The sliding openings 9 provided on the concave seat 8 are used to cooperate with the sliding of the slider 16, and the rotation holes 10 provided are used to cooperate with the rotation of the rotation rod 13, and the installed L-shaped plate 11 is used to cooperate with the installation and fixation of the electric push rod 19;

[0020] like Figure 3 As shown, by turning on the electric push rod 19 to drive the output end, the rack 20 can be pushed to the left;

[0021] like Figure 3 As shown, the front and rear ends of the bidirectional screw 12 are respectively fixedly mounted with a rotating rod 13, and the rotating rod 13 is movably mounted in the rotating hole 10. Under the movement of the rack 20, due to the meshing between the rack 20 and the gear 14, the rack 20 moves and drives the gear 14 to rotate. After the gear 14 rotates, it drives the rotating rod 13 to rotate in the rotating hole 10, and the rotating rod 13 drives the bidirectional screw 12 to rotate;

[0022] like Figure 3As shown, the movable plate 15 is provided with a group of symmetrical front and rear plates, and a group of left and right symmetrical sliders 16 are fixedly installed on the bottom surface of the movable plate 15. The sliders 16 are movably installed in the sliding mouth 9. A screw hole 17 is provided on the front end wall of the movable plate 15, and the movable plate 15 is threadedly connected with the bidirectional screw 12 through the screw hole 17. Under the rotation of the bidirectional screw 12, because the front and rear symmetrical movable plates 15 are respectively threadedly connected with the bidirectional screw 12 through the screw holes 17 provided on the front end wall, the front and rear symmetrical movable plates 15 will respectively make relative movement operations along the bidirectional screw 12 in the concave seat 8 through the screw holes 17, and the slider 16 installed on the bottom surface of the movable plate 15 will slide in the sliding mouth 9 to limit the movement of the movable plate 15.

[0023] like Figure 3 As shown, the vertical part of the L-shaped clamp seat 18 is fixedly installed on the top surface of the movable plate 15. Under the relative movement of the symmetrical movable plates 15, the L-shaped clamp seat 18 installed on the top surface of the movable plate 15 will move synchronously, and the front-to-back symmetrical L-shaped clamp seats 18 will make relative movement operations until the circuit board is clamped between the L-shaped clamp seats 18. In this way, by adjusting the distance between the front-to-back symmetrical L-shaped clamp seats 18, circuit boards of different sizes can be quickly clamped, positioned, and fixed.

[0024] It should be noted that the present invention is a laser marking machine for the production of electronic components.

The electric push rod 19 will drive the output end to the left to push the rack 20 installed on the output end. At this time, because the rack 20 and the gear 14 are meshed with each other, the rack 20 will drive the gear 14 to rotate under the action of meshing after moving. During the rotation of the gear 14, because the gear 14 is installed on the end wall of the rotating rod 13 at the rear end of the bidirectional screw 12, the gear 14 will drive the rotating rod 13 installed at the front and rear ends of the bidirectional screw 12 to rotate in the rotating hole 10 opened on the front and rear side walls of the concave seat 8, and the rotating rod 13 will drive the bidirectional screw 12 to rotate in the notch of the concave seat 8. At this time, because the front-to-back symmetrical activity inside the concave seat 8 The movable plate 15 is respectively connected to the bidirectional screw 12 through the screw holes 17 opened on the front end wall, so the front and rear symmetrical movable plates 15 will respectively move relatively in the concave seat 8 along the bidirectional screw 12 through the screw holes 17, and when moving, the left and right symmetrical sliders 16 installed on the bottom surface of the movable plate 15 will slide in the left and right symmetrical sliding holes 9 opened on the inner bottom surface of the concave seat 8. At the same time, the movable plate 15 will drive the L-shaped clamping seat 18 installed on the top surface to move synchronously, and the front and rear symmetrical L-shaped clamping seats 18 will make relative movement operations until the circuit board is positioned and clamped between the L-shaped clamping seats 18 according to the size of the circuit board. By adjusting the distance between the L-shaped clamping seats 18, the purpose of quickly positioning and clamping circuit boards of different sizes can be achieved, and manual operation is not required during adjustment, and the operation is simple and fast, thereby not only improving the applicability of the positioning and fixing mechanism 7, but also improving the working efficiency of the laser marking machine when marking circuit boards of different sizes.
