[0002] After the electric energy meter is manufactured, it is necessary to use laser marking to engrave QR codes, serial numbers and other information on the surface of the electric energy meter. In the prior art, a variety of laser marking machines are proposed, such as the laser marking method, laser marking equipment and system proposed in the Chinese invention patent with publication number CN105562937B. The product conveyor line of the laser marking equipment drives the product to move, and the first laser head and the second laser head mark the product at the same time. After the first laser head and the second laser head mark one product, they mark another product separated from the product by one product, so that the running speed of the product conveyor line can be doubled, so the marking speed can be doubled, and the marking efficiency is improved without adding laser marking equipment and at a low cost.

[0003] The above-mentioned laser marking machine adopts a fixed laser head, which causes the product and the laser head to move relative to each other when the laser head marks the product. When marking multiple lines of a product or marking a large area of ​​a QR code, problems such as wrong lines are prone to occur. Therefore, a laser marking machine for an electric energy meter is proposed in which the laser head moves synchronously with the electric energy meter, so that the laser head and the electric energy meter remain relatively stable, thereby improving the marking quality. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a laser marking machine for electric energy meters, in which the laser head moves synchronously with the electric energy meter during marking, avoiding problems such as misalignment, improving the marking quality and marking complexity, and having good practicality.

The conveyor belt mechanism is installed on the frame and is used to convey the electric energy meter; the machine also comprises a slide, a sealing cover, a lifting cylinder, a push block, a wedge block and a reset assembly. The slide is slidably installed on the frame. The sealing cover is lifted and lowered on the slide by a lifting cylinder. The sealing cover is located on the conveyor belt mechanism. The laser head is installed on the sealing cover. The laser head is used to mark the electric energy meter. A plurality of push blocks are evenly installed on the conveyor belt mechanism. The plurality of push blocks are used to push the slide to move. The wedge block is installed on the frame. The wedge block is located at the rear side of the conveyor belt mechanism. The wedge block lifts the slide to separate the slide from the push block. The reset assembly is installed on the frame. The reset assembly is transmission-connected with the slide. When the slide is separated from the push block, the reset assembly resets the slide. During operation, the conveyor belt mechanism transports a plurality of electric energy meters to the rear, and the plurality of electric energy meters are respectively located between the plurality of push blocks. When the electric energy meters reach the bottom of the sealing cover, The push block contacts the slide, so that the push block pushes the slide to move synchronously, and the slide drives the reset component to store energy. The slide drives the sealing cover to move synchronously with the electric energy meter through the lifting cylinder. The piston rod of the lifting cylinder contracts to buckle the sealing cover on the conveyor belt mechanism, and the sealing cover buckles the electric energy meter cover. The laser head is aligned with the marking position of the electric energy meter and marks. Since the laser head moves synchronously with the electric energy meter and remains relatively stable, the laser head can mark multiple lines of logos and large-area two-dimensional codes. After the marking is completed, the piston rod of the lifting cylinder extends to lift the sealing cover above the electric energy meter. When the slide meets the wedge block, the slide rises along the upper surface of the wedge block and separates from the push block. At this time, the reset component releases energy to push the slide back to its initial position to prepare for the next electric energy meter marking.

When the slide is separated from the push block, the gravitational potential energy of the counterweight block is released to push the slide backward through multiple balls, so that the slide is blocked by the push block in front again, thereby preparing for the marking of the next electric energy meter.

The conveyor belt mechanism 2 is mounted on the frame 1 and is used to transport the electric energy meter; it also comprises a slide 4, a sealing cover 5, a lifting cylinder 6, a push block 7, a wedge block 8 and a reset assembly. The slide 4 is slidably mounted on the frame 1. The sealing cover 5 is lifted and lowered on the slide 4 by the lifting cylinder 6. The sealing cover 5 is located on the conveyor belt mechanism 2. The laser head 3 is mounted on the sealing cover 5. The laser head 3 is used to mark the electric energy meter. A plurality of push blocks 7 are evenly mounted on the conveyor belt mechanism 2.

When the slide 4 After disengaging from the push block 7, the reset assembly resets the slide 4; the reset assembly includes an L-shaped tube 9, a plurality of balls 10 and a counterweight 11, the L-shaped tube 9 is installed on the frame 1, the L-shaped tube 9 is provided with a horizontal portion parallel to the conveyor belt mechanism 2 and a vertical portion perpendicular to the conveyor belt mechanism 2, the vertical portion is located above the rear side of the conveyor belt mechanism 2, long slide grooves are provided on both sides of the L-shaped tube 9, a plurality of balls 10 are rollingly installed in the L-shaped tube 9, a rotating shaft is rotatably installed in the middle of the ball 10 located at the front, the rotating shaft passes through the long slide groove of the L-shaped tube 9 and is connected to the slide 4, the ball 10 located at the rear is installed with a counterweight 11, and the counterweight 11 is located on the vertical portion of the L-shaped tube 9; the ball 10 is made of lightweight material; it also includes a track 12 and a roller 13, the track 12 is horizontally installed on the frame 1, the roller 13 is rotatably installed on the slide 4, and the roller 13 rolls on the track 12.

[0027] During operation, the conveyor belt mechanism 2 conveys multiple electric energy meters to the rear, and the multiple electric energy meters are respectively located between the multiple push blocks 7. When the electric energy meter reaches the bottom of the sealing cover 5, the push block 7 contacts the slide 4, so that the push block 7 pushes the slide 4 to move synchronously. The slide 4 drives the multiple balls 10 to roll to the rear of the L-shaped tube 9 through the rotating shaft, so that the multiple balls 10 drive the counterweight block 11 to rise along the vertical part of the L-shaped tube 9, so that the gravitational potential energy of the counterweight block 11 is increased.

[0029] When the sealing cover 5 buckles the electric energy meter cover, the output shaft of the motor 17 drives a shaft rod 14 to rotate clockwise, and the two bevel gears 20 of the shaft rod 14 mesh with the two bevel gears 16 to drive the two shaft rods 18 to rotate synchronously relative to each other. At the same time, the two shaft rods 18 respectively mesh with the other two bevel gears 20 and the other two bevel gears 16 to drive the other shaft rod 14 to rotate counterclockwise, thereby driving the two paddles 15 and the two paddles 19 to rotate inward synchronously to align the electric energy meter to the middle of the sealing cover 5, so as to adjust the position of the electric energy meter and improve the consistency of the marking position.

The gravitational potential energy of the weight 11 increases, and the slide 4 drives the sealing cover 5 to move synchronously with the electric energy meter through the lifting cylinder 6, the mounting seat 25 and the horizontal push cylinder 26.
