Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1-7 , the present invention provides a technical solution: a laser etching device for processing die patterns, including a frame 1, on which a mounting plate 2 is vertically slidably connected, and a drive unit 3 for driving the vertical sliding of the mounting plate 2 is provided on the frame 1. A laser etching unit 4 for laser etching operation is installed on the mounting plate 2 through a servo mechanism; a carrier plate 5 is installed on the frame 1, and fixing members for fixing the workpiece 6 are slidably connected to both sides of the carrier plate 5; the fixing member includes a pressing plate 7 slidably connected to the carrier plate 5, and a linkage member is provided between the mounting plate 2 and the pressing plate 7. When the drive unit 3 drives the pressing plate 7 to slide downward, the pressing plate 7 is driven to slide through the linkage member to fix the fixing member; a ejecting member is further provided between the frame 1 and the mounting plate 2, and a return spring 12 is provided between the pressing plate 7 and the mounting plate 2. During the stroke of the return spring 12 to restore its elastic deformation, the workpiece 6 is ejected through the ejecting member.

[0028] Specifically, the laser etching equipment for processing die patterns includes a frame 1. A mounting plate 2 is vertically slidably connected to the frame 1. A driving unit 3 for driving the vertical sliding of the mounting plate 2 is provided on the frame 1. Specifically, the driving unit 3 can be a servo cylinder or a hydraulic rod. A laser etching unit 4 for laser etching operation is installed on the mounting plate 2 through a servo mechanism. More specifically, the servo mechanism is a prior art, and its structure and working principle will not be elaborated here. It can realize the sliding of the laser etching unit 4 in the front, back, left, and right directions, facilitating the laser etching operation on the workpiece 6. A bearing plate 5 is installed on the frame 1. Fixing members for fixing the workpiece 6 are slidably connected to both sides of the bearing plate 5. Therefore, during use, after the fixing members fix the workpiece 6, the situation of the workpiece 6 shaking can be reduced, and the laser etching effect is better. The fixing member includes a pressing plate 7 slidably connected to the bearing plate 5. A linkage member is provided between the mounting plate 2 and the pressing plate 7. When the driving unit 3 drives the pressing plate 7 to slide downward, the pressing plate 7 is driven to slide through the linkage member to fix the fixing member, so that there is no need to separately set a driving source to actively drive the pressing plate 7 to slide, improving work efficiency. A jacking member is further provided between the frame 1 and the mounting plate 2 to facilitate jacking out the processed workpiece 6. A return spring 12 is provided between the pressing plate 7 and the mounting plate 2. During the process of the return spring 12 restoring its elastic deformation, the workpiece 6 is jacked out through the jacking member. Specifically, during work, the workpiece 6 is installed at a predetermined working position. Then, the driving member drives the mounting plate 2 to slide downward. During the downward sliding of the mounting plate 2, the pressing plate 7 is driven to slide through the linkage member, so that the pressing plate 7 fixes the workpiece 6, thus eliminating the need to separately set a driving source to actively drive the pressing plate 7 to slide, improving work efficiency and saving energy consumption. After the workpiece 6 is processed, the workpiece 6 is unlocked during the upward resetting process of the mounting plate 2. Then, after the pressing plate 7 is unlocked and restricted, the return spring 12 drives the pressing plate 7 to slide during the process of restoring its elastic deformation. During this stroke, the workpiece 6 is jacked out through the jacking member, facilitating the blanking of the workpiece 6 and further improving the practicability of the equipment.

[0029] In the embodiment provided by the present utility model, the linkage member includes a connecting rod 10 fixedly connected to the bottom of the mounting plate 2. A driving block 11 is fixedly connected to the bottom of the connecting rod 10. The pressing plate 7 is fixedly connected with a force-receiving block 8 through a guide rod. The driving block 11 is intermittently in contact with the force-receiving block 8. The driving block 11 is a wedge-shaped block. A wedge-shaped groove 9 adapted to the wedge-shaped block is formed on the force-receiving block 8. The wedge-shaped block is adapted to the wedge-shaped groove 9, which can better drive the pressing plate 7 to slide and has a better use effect.

[0030] In the embodiment provided by the present utility model, a positioning groove is formed on the bearing plate 5. The return spring 12 is installed between the pressing plate 7 and the positioning groove. Therefore, when there is no external force restricting the pressing plate 7, the return spring 12 drives the pressing plate 7 to slide in the reverse direction during the process of restoring its elastic deformation, facilitating the blanking of the workpiece 6.

[0031] In the embodiment provided by the present utility model, a limiting member is further arranged between the extrusion plate 7 and the bearing plate 5 to improve the stability of the extrusion plate 7 during sliding. The limiting member includes a limiting groove 13 formed on the bearing plate 5, and a limiting block 14 is fixedly connected to the bottom of the extrusion plate 7. The limiting block 14 is slidably connected in the limiting groove 13, and the use effect is better.

[0032] In the embodiment provided by the present utility model, the ejecting member includes an ejecting rod 17 slidably connected vertically to the bearing plate 5. An ejecting cap is fixedly connected to the top of the ejecting rod 17. A transmission member is arranged between the ejecting rod 17 and the limiting block 14. Specifically, the transmission member includes an ejecting block 18 fixedly connected to the bottom of the ejecting rod 17. A connecting frame 15 is fixedly connected to the limiting block 14, and a pressing block 16 is fixedly connected to the connecting frame 15. The pressing block 16 is intermittently abutted against the ejecting block 18. Therefore, when the reset member restores its elastic deformation and drives the extrusion plate 7 to slide in the reverse direction, at this moment, the pressing block 16 is driven to slide through the connecting frame 15, and the ejecting rod 17 is driven to slide upward through the cooperation between the pressing block 16 and the ejecting block 18, facilitating the ejection of the workpiece 6.

[0033] In the embodiment provided by the present utility model, a positioning spring 19 is further arranged between the ejecting block 18 and the bearing plate 5. The purpose of arranging the positioning spring 19 is to improve the stability during the installation of the positioning rod. The elastic force of the positioning spring 19 drives the ejecting rod 17 to slide downward; the elastic coefficient of the reset spring 12 is greater than that of the positioning spring 19, facilitating the ejection of the workpiece 6.

[0034] In the embodiment provided by the present utility model, anti-slip stripes are formed on the extrusion plate 7 to improve the stability when holding the workpiece 6.

[0035] It should be noted that the electrical equipment involved in this application can be powered by a storage battery or an external power supply.
