The left end of the bidirectional threaded rod is rotatably connected to the left inner wall of the adjustment box. When the driving motor works, it drives the bidirectional threaded rod to rotate, causing the ball nut pair to move left and right on the outside of the bidirectional threaded rod.

[0009] According to the above technical solution, rectangular grooves for accommodating the movement of the ball nut pair are provided on the left and right sides of the front of the adjustment box, which are used for guiding and limiting the left and right movement of the ball nut pair.

[0010] According to the above technical solution, driven frames are provided in the middle of the front and back of the driving frame. The middle part inside the driven frame is rotatably connected to the middle part inside the second rotating block. The driving frame is rotatably connected to the second rotating block through the driven frame. When the driving frame moves, it drives the second rotating block to rotate, and drives the rotating arm plate through the second spring on the rear side of the second rotating block, so that the first spring on the rotating arm plate drives the first rotating block to rotate inside the positioning frame.

[0011] According to the above technical solution, a second clamping assembly is further included. The second clamping assembly is composed of an electric telescopic rod, a third spring, a first connecting plate, a first positioning column, a fourth spring, a second connecting plate, a second positioning column, a supporting spring, a fixed frame, a rotating wall scraping frame, a positioning pulley and a wall scraping plate.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, When placing the workpiece, control the driving motor to work so that the driving frame is located on both sides of the workpiece. Subsequently, control the electric telescopic rod to work. The electric telescopic rod pulls one side of the driving frame to move, causing the rotating arm plate to rotate until the positioning pulley contacts the workpiece on the outside. The positioning pulley squeezes and positions the front and rear sides of the workpiece, which can squeeze the outer walls of the front and rear sides of the workpiece, avoiding deviation caused by poor clamping effect on the front and rear sides of the workpiece during subsequent laser marking. When it is necessary to perform adaptive clamping and positioning work on the left and right sides of the workpiece, the positioning pulley fixedly clamps the front and rear sides of the workpiece. Subsequently, start the driving motor to make the positioning pulley slide on the outer wall of the workpiece. At the same time, the positioning post one and the positioning post two on the driving frame contact the outer walls of both sides of the workpiece, and the positioning post one and the positioning post two clamp the top walls of both sides of the workpiece, avoiding the workpiece shaking left and right due to small clamping force on both sides, making the clamping and positioning more stable when the device performs laser marking on the workpiece. When the laser marking head processes the top of the workpiece, the material on the surface of the workpiece will evaporate into a gaseous state during laser marking, and then quickly condense and deposit when encountering cold air or cold surfaces such as the tabletop, forming a black film or particles and falling on the front and rear sides of the workpiece. After the laser marking work is completed, the scraping wall frame rotates, and the scraping wall plate pushes the accumulated black particles into the chip removal groove, enabling the device to quickly clean the generated black particles, avoiding the accumulation of black particles on the top of the machine body causing the surface to be uneven, and ensuring that the surface of the machine body is relatively smooth. By setting the spring three and the spring four, when the left and right sides of the workpiece contact the positioning post one and the positioning post two, the uneven parts on the outer wall of the workpiece contact the positioning post one and the positioning post two respectively, so that the degree of contraction of the spring three and the spring four can be automatically adjusted according to the position of the uneven parts, enabling the device to perform adaptive adjustment according to the shape of both sides of the workpiece.

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

[0020] Embodiment 1: Please refer to Figures 1-5 , the present invention provides a technical solution: A laser marking machine for electronic component production includes a machine tool body 1, and also includes a drive assembly 6 and a clamping assembly one 7. A fixed arm 2 is fixedly connected to the back of the machine tool body 1, a work box 3 is fixedly connected to the top of the fixed arm 2, a laser marking head 4 is arranged in the middle of the inner bottom of the work box 3, and chip removal grooves 5 are opened on the front and back sides inside the machine tool body 1.

[0021] Among them, the drive assembly 6 includes: An adjustment box 601, the adjustment box 601 is fixedly connected to the rear side of the top of the machine tool body 1, a drive motor 602 is fixedly connected to the right side of the adjustment box 601, the output shaft of the drive motor 602 is fixedly connected to a bidirectional threaded rod 603, and a ball nut pair 604 is threadedly connected to the outside of the bidirectional threaded rod 603. When the drive motor 602 works, it drives the bidirectional threaded rod 603 to rotate. At this time, the ball nut pair 604 moves left and right on the outside of the bidirectional threaded rod 603.

[0022] The clamping assembly one 7 includes: Move the moving frame 701. The moving frame 701 is fixedly connected to the front of the ball screw nut pair 604. A extension plate 702 is fixedly connected to the right side of the moving frame 701. A positioning frame 703 is fixedly connected to the front of the extension plate 702. A first rotating block 704 is rotatably connected to the middle of the positioning frame 703. A first spring 705 is fixedly connected to the front of the first rotating block 704. One end of the first spring 705 away from the first rotating block 704 is fixedly connected to a rotating arm plate 706. A second spring 707 is fixedly connected to the front of the rotating arm plate 706. One end of the second spring 707 away from the rotating arm plate 706 is fixedly connected to a second rotating block 708. A driving frame 709 is rotatably connected to the middle of the second rotating block 708.

[0023] A circular groove is formed in the middle of the right side of the adjusting box 601. The output shaft of the driving motor 602 penetrates through the circular groove and extends into the adjusting box 601 and is fixedly connected to the right end of the bidirectional threaded rod 603. The left end of the bidirectional threaded rod 603 is rotatably connected to the left inner wall of the adjusting box 601. When the driving motor 602 works, it drives the bidirectional threaded rod 603 to rotate, so that the ball screw nut pair 604 moves left and right on the outside of the bidirectional threaded rod 603.

[0024] Rectangular grooves for accommodating the left and right movement of the ball screw nut pair 604 are formed on the left and right sides of the front of the adjusting box 601, which are used for guiding and limiting the left and right movement of the ball screw nut pair 604.

[0025] Driven frames are arranged in the middle of the front and back of the driving frame 709. The middle of the driven frame is rotatably connected to the middle of the second rotating block 708. The driving frame 709 is rotatably connected to the second rotating block 708 through the driven frame. When the driving frame 709 moves, it drives the second rotating block 708 to rotate, and drives the rotating arm plate 706 through the second spring 707 on the rear side of the second rotating block 708, so that the first spring 705 on the rotating arm plate 706 drives the first rotating block 704 to rotate in the positioning frame 703.

[0026] When laser marking of the workpiece is required, place the workpiece on the top of the machine tool body 1, and then control the laser marking head 4 in the working box 3 to work to perform laser marking on the surface of the workpiece.

[0027] When placing the workpiece, control the driving motor 602 to work, so that the driving motor 602 drives the bidirectional threaded rod 603 to rotate. When the bidirectional threaded rod 603 rotates, the ball nut pair 604 moves on the bidirectional threaded rod 603, and can be adjusted according to the workpiece size. Subsequently, control the electric telescopic rod 801 to work, and the electric telescopic rod 801 pulls the driving frame 709 to move close to one side of the inner wall of the moving frame 701, so that the rotating arm plate 706 rotates on the front and rear sides of the driving frame 709. When the rotating arm plate 706 rotates to contact the outer side of the positioning pulley 811 with the workpiece, the positioning pulley 811 squeezes and positions the front and rear sides of the workpiece. At this time, the support spring 808 is squeezed. By providing the support spring 808, the outer walls of the front and rear sides of the workpiece can be squeezed, avoiding deviation caused by poor clamping effect on the front and rear sides of the workpiece during subsequent laser marking.

[0028] Embodiment 2: Please refer to Figures 1-7 , on the basis of Embodiment 1, the present invention provides a technical solution: further comprising a clamping assembly II 8, and the clamping assembly II 8 is composed of an electric telescopic rod 801, a spring III 802, a connecting plate I 803, a positioning column I 804, a spring IV 805, a connecting plate II 806, a positioning column II 807, a support spring 808, a fixing frame 809, a rotating wall scraping frame 810, a positioning pulley 811 and a wall scraping plate 812.

[0029] The electric telescopic rod 801 is fixedly connected to the middle of the left side of the driving frame 709, the spring III 802 is fixedly connected to the left side inside the driving frame 709, the connecting plate I 803 is fixedly connected to the other end of the spring III 802, the positioning column I 804 is fixedly connected to the side of the connecting plate I 803 away from the spring III 802, the spring IV 805 is fixedly connected to the left side inside the driving frame 709 and is located on the front and rear sides of the spring III 802, the connecting plate II 806 is fixedly connected to the other end of the spring IV 805, the positioning column II 807 is fixedly connected to the other side of the connecting plate II 806, the fixing frame 809 is fixedly connected to the side of the rotating arm plate 706 away from the moving frame 701, the rotating wall scraping frame 810 is rotatably connected to the middle inside the fixing frame 809, the positioning pulley 811 is rotatably connected to the side of the rotating wall scraping frame 810 away from the fixing frame 809, the wall scraping plate 812 is fixedly connected to the bottom of the rotating wall scraping frame 810, and the support spring 808 is fixedly connected to the back of the rotating wall scraping frame 810.

[0030] The electric telescopic rod 801 has a telescopic end, and the side of the driving frame 709 close to the inner wall of the moving frame 701 is fixedly connected to the telescopic end of the electric telescopic rod 801.

[0031] A circular groove for accommodating the movement of the positioning column I 804 and the positioning column II 807 is provided on the right side of the driving frame 709, and the positioning column I 804 and the positioning column II 807 move in the circular groove.

[0032] One end of the support spring 808 away from the rotating scraping wall frame 810 is fixedly connected to the outer wall of the rotating arm plate 706, and is used to support the rotating scraping wall frame 810.

[0033] When it is necessary to perform adaptive clamping and positioning work on the left and right sides of the workpiece, at this time, the positioning pulley 811 fixedly clamps the front and rear sides of the workpiece. Then, the driving motor 602 is started. When the driving motor 602 works, it controls the ball screw pair 604 to move on the outer side of the bidirectional threaded rod 603, so that the positioning pulley 811 slides on the outer wall of the workpiece. At the same time, the positioning post one 804 and the positioning post two 807 on the driving frame 709 contact the outer walls of both sides of the workpiece. At this time, the workpiece squeezes the positioning post one 804 and the positioning post two 807, so that the spring three 802 and the spring four 805 are compressed. At the same time, the positioning post one 804 and the positioning post two 807 clamp the top walls of both sides of the workpiece, avoiding the left and right shaking of the workpiece caused by the small clamping force on both sides of the workpiece, and making the clamping and positioning of the device more stable when laser marking the workpiece.

[0034] When the laser marking head processes the top of the workpiece, the material on the surface of the workpiece will evaporate into a gaseous state during laser marking. Then, when it encounters a cold surface such as cold air or the tabletop, it will quickly condense and deposit, forming a black film or particles, and falling on the front and rear sides of the workpiece. After the laser marking work is completed, the electric telescopic rod 801 is controlled to work, so that the electric telescopic rod 801 pushes the driving frame 709, so that the rotating arm plate 706 rotates in the middle of the front and back of the driving frame 709. At the same time, the positioning pulley 811 separates from the outer walls of the front and rear sides of the workpiece, so that the elasticity of the support spring 808 is restored. At this time, the support spring 808 drives the rotating scraping wall frame 810 to move, so that the scraping plate 812 at the bottom of the rotating scraping wall frame 810 scrapes the top surface of the machine tool body 1. At the same time, as the rotating scraping wall frame 810 rotates, the scraping plate 812 pushes the accumulated black particles into the chip removal groove 5, so that the device can quickly clean the generated black particles, avoid the accumulation of black particles on the top of the machine tool body 1 causing the surface to be uneven, and ensure that the surface of the machine tool body 1 is relatively smooth.

[0035] By setting the spring three 802 and the spring four 805, when the left and right sides of the workpiece contact the positioning post one 804 and the positioning post two 807, the concave and convex parts on the outer wall of the workpiece contact the positioning post one 804 and the positioning post two 807 respectively, so that the degree of contraction of the spring three 802 and the spring four 805 can be automatically adjusted according to the position of the concave and convex parts, and the device can be adaptively adjusted according to the shape of both sides of the workpiece.
