Background Technology

[0002] After an electricity meter passes inspection, a qualification mark needs to be engraved on it and verified. However, due to the differences in size and positioning methods between single-phase electricity meters, three-phase electricity meters, and data acquisition terminals, existing electricity meter engraving and verification devices usually adopt a "dedicated meter, dedicated stand" design. This results in relatively simple existing electricity meter engraving and verification devices, which have problems such as lack of compatibility, high cost, and large footprint, and have certain limitations in the layout of electricity meter compatibility production lines. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an engraving and verification device and method that is automatically compatible with single-phase and three-phase energy meters and data acquisition terminals, so as to solve the problems of lack of compatibility, high cost and large footprint of existing engraving and verification devices.

[0012] The lifting and positioning component is located below the conveyor line, with one component at each of the engraving station and the verification station. It is fixed to the profile frame component by bolts and is used to lift the compatible tooling tray to a preset height to facilitate engraving and verification work.

[0013] Furthermore, when the laser engraving component engraves a three-phase energy meter or data acquisition terminal, the compatible tooling tray is located at a preset height raised by the lifting and positioning component, the positioning component is located on one side of the laser engraving component, and the side-pushing component is in operation.

[0014] Furthermore, the positioning component includes a translational linear slide rail, a pressing linear slide rail mounting plate, a translational rodless cylinder, a mounting plate, and a shim block;

[0015] The mounting plate is fixed to the profile frame assembly by bolts, and the linear slide rail is fixed to the mounting plate by bolts.

[0031] The linear bearing is fixed to the lifting fixing plate by bolts and sleeved on the outer periphery of the guide shaft;

[0032] The positioning pin and the support column are fixed to the lifting positioning plate by bolts, wherein the positioning pin is used to insert into the positioning hole of the compatible tooling pallet, and the support column is used to support the compatible pallet;

[0033] The lifting cylinder is fixed to the lifting fixing plate by bolts, and the floating joint connects the lifting positioning plate and the lifting cylinder through its threaded hole and stud.

[0034] When the lifting cylinder is activated, it drives the lifting positioning plate to move upward, causing the positioning pin and support column to lift the compatible tooling pallet to a preset height.

[0035] Furthermore, the engraving and verification device for the automatic compatible single-phase and three-phase energy meters and data acquisition terminals also includes a dust collection component, which is located below the positioning component and fixed to the profile frame component by bolts.

[0039] When engraving a three-phase energy meter or data acquisition terminal, the positioning component is controlled to move to one side of the laser engraving component to avoid interference, and the side pushing component is controlled to position the three-phase energy meter or data acquisition terminal from both sides of the conveyor line.

[0040] When engraving a single-phase energy meter, the positioning component is controlled to position the single-phase energy meter, and the side-pushing component is controlled not to move.

[0041] The laser engraving component is controlled to adjust the engraving focal length according to the meter shape and to engrave the qualified mark on the electricity meter.

[0042] After the engraving is completed, the conveyor line is controlled to transport the compatible tooling tray to the verification station;

[0044] The control light source component illuminates the electricity meter, the verification component adjusts the imaging focal length according to the meter shape, judges the engraved mark, and uploads the judgment result.

[0045] Furthermore, when engraving a three-phase energy meter or data acquisition terminal, the positioning component is moved to one side of the laser engraving component to avoid interference. This includes: driving a translation rodless cylinder to extend its piston rod, which drives the pressing linear slide rail mounting plate to move horizontally along the translation linear slide rail, thereby moving the horizontal positioning strip, the vertical positioning strip, and the pressing fixing plate as a whole to one side of the laser engraving component to avoid the three-phase energy meter or data acquisition terminal.

[0046] As can be seen from the above technical solutions, this application provides an automatic engraving and verification device for single-phase and three-phase energy meters and data acquisition terminals, including: a light source assembly, a verification assembly, a laser engraving assembly, a profile frame assembly, a positioning assembly, a side-pushing assembly, a conveyor line, and a lifting and positioning assembly;

[0047] The conveyor line is fixed to the profile frame assembly by bolts and is used to transport compatible tooling pallets. The engraving station and the verification station are arranged sequentially along the transport direction of the conveyor line.

[0048] The laser engraving component is located at the engraving station, above the conveyor line, and is movably mounted on the profile frame assembly. It is used to move up and down according to the differences in different face shapes to adjust the engraving focal length and is used to engrave the energy meter.

[0049] The positioning component is located below the laser engraving component and is movably mounted on the profile frame component. It is used to move to one side of the laser engraving component when the laser engraving component is engraving a three-phase energy meter or a data acquisition terminal, and to position the component when the laser engraving component is engraving a single-phase energy meter.

[0050] The side-pushing component is located below the positioning component and is fixed to the two side supports of the conveyor line by bolts. Its pushing direction is perpendicular to the conveying direction of the conveyor line, and it is used to position the three-phase energy meter or data acquisition terminal from both sides.

[0051] The light source assembly and the verification assembly are located at the verification station, wherein the light source assembly is located above the conveyor line and directly facing the compatible tooling tray, and is fixed to the profile frame assembly by bolts;

[0052] The verification component is an industrial camera, located above the light source component and movably mounted on the profile frame component, used to adjust the imaging focal length according to different phenotypes to make the image clear;

[0053] The lifting and positioning component is located below the conveyor line, with one component at each of the engraving station and the verification station. It is fixed to the profile frame component by bolts and is used to lift the compatible tooling tray to a preset height to facilitate engraving and verification work.

[0054] This solution integrates multiple traditional equipment sets into a single-line, dual-station layout through the coordinated operation of positioning, side-pushing, laser engraving, verification, and lifting positioning components. This solves the problems of incompatibility, high cost, and large footprint of existing engraving and verification devices. When switching from a single-phase energy meter to a three-phase energy meter or data acquisition terminal, the positioning component moves out of the engraving station to avoid large-sized products and prevent interference. Subsequently, the side-pushing component pushes the three-phase energy meter or data acquisition terminal from the side of the conveyor line to complete precise positioning before engraving. At the same time, the laser engraving and verification components automatically adjust the engraving focal length and imaging focal length according to the product height, while the lifting positioning component simultaneously lifts the tray to a preset height at both the engraving and verification stations. This completes the engraving and verification of qualified energy meters on a compatible production line, effectively supporting single-phase and three-phase energy meters and data acquisition terminals, reducing costs and equipment footprint.

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0063] This application provides an automatic engraving and verification device compatible with single-phase and three-phase energy meters and data acquisition terminals. Please refer to Figures 1-3. It includes: a light source assembly 1, a verification assembly 2, a laser engraving assembly 3, a profile frame assembly 4, a positioning assembly 6, a side-pushing assembly 7, a conveyor line 8, and a lifting and positioning assembly 9.

[0064] The conveyor line 8 is fixed to the profile frame assembly 4 by bolts and is used to convey compatible tooling trays that are compatible with single-phase energy meters, three-phase energy meters and data acquisition terminals. The engraving station and the verification station are set up in sequence along the conveying direction of the conveyor line 8.

[0065] The laser engraving component 3 is located at the engraving station, above the conveyor line 8, and is movably mounted on the profile frame component 4. The laser engraving component 3 can move up and down vertically. It can automatically adjust its position according to the surface height differences of different products, such as single-phase energy meters, three-phase energy meters, and data acquisition terminals, to ensure that the laser focus is always located at the product engraving station, thereby ensuring the clarity and consistency of the engraving to meet the focal length requirements of products of different heights. For example, different laser marking templates are available for different surface types, and the laser engraving component 3 can be controlled by laser marking software to adjust the focal length.

[0066] Positioning component 6 is located below laser engraving component 3 and is movably mounted on profile frame component 4. When processing three-phase energy meters or data acquisition terminals, positioning component 6 can be moved out of the engraving station as a whole to make room for the three-phase energy meters or data acquisition terminals. Positioning component 6 includes a translational linear slide rail 16, a pressing linear slide rail mounting plate 17, a translational rodless cylinder 18, a mounting plate 19, and a shim block 23. The mounting plate 19 is fixed to the profile frame component 4 with bolts, serving as the fixed base for positioning component 6. The translational linear slide rail 16 is fixed to the mounting plate 19 with bolts, and its guide... The rail direction is perpendicular to the conveying direction of the conveyor line 8; the translation rodless cylinder 18 is fixed to the mounting plate 19 by bolts, and its driving end is connected to the pressing linear slide rail mounting plate 17, which is used to drive the pressing linear slide rail mounting plate 17 to reciprocate along the translation linear slide rail 16; the pressing linear slide rail mounting plate 17 is fixed to the slider of the translation linear slide rail 16 by the shim block 23, thereby realizing the movement of the entire positioning component 6 in a direction perpendicular to the conveyor line 8, so as to move the positioning component 6 out of the engraving station as a whole when processing three-phase energy meters or data acquisition terminals, so as to avoid interference with large-size products;

[0067] The side push assembly 7 is located below the positioning assembly 6 and is fixed to the brackets on both sides of the conveyor line 8 by bolts. When the positioning assembly 6 moves out of the engraving station, before engraving the three-phase energy meter or data acquisition terminal, the side push assemblies 7 on both sides push the three-phase energy meter or data acquisition terminal to the preset engraving position to complete the precise positioning before engraving.

[0068] The verification station is equipped with a light source assembly 1 and a verification assembly 2. The light source assembly 1 is fixed to the profile frame assembly 4 by bolts, and is located above the conveyor line 8 and directly facing the compatible tooling tray on the conveyor line 8. The light source assembly 1 is a dedicated lighting source. The verification assembly 2 is an industrial camera, which is movably mounted on the profile frame assembly 4 and located above the light source assembly 1. It is used to acquire images of the qualified markings. The imaging focal length can be adjusted according to different markings to make the image clear. For example, during the verification process, the light source assembly 1 illuminates the qualified markings engraved on the single-phase energy meter. The verification assembly 2 automatically adjusts the imaging focal length according to the size of the single-phase energy meter. After adjusting the imaging focal length, it takes a picture of the qualified marking. The system compares the acquired image with the standard template, automatically determines whether the qualified marking is complete and clear, and archives the results.

[0069] The lifting and positioning component 9 is located below the conveyor line 8, with one component at each of the engraving and verification stations. It is fixed to the profile frame component 4 by bolts and is used to lift the compatible tooling pallet so that it is removed from the conveyor surface and reaches the preset positioning height to cooperate with the engraving and verification work.

[0070] In one specific implementation, the laser engraving component 3 and the verification component 2 are movably mounted on the profile frame component 4 via an electric slide table, which drives the laser engraving component 3 and the verification component 2 to move up and down in the vertical direction, thereby adapting to the engraving focal length and imaging focal length requirements of energy meters of different heights.

[0071] In one specific implementation, the laser engraving component 3 and the verification component 2 can also be movably mounted on the profile frame component 4 via a cylinder and motor synchronous belt mechanism.

[0072] In one specific embodiment, when the laser engraving component 3 engraves a three-phase energy meter or data acquisition terminal, the compatible tooling tray is located at a preset height lifted by the lifting and positioning component 9, the positioning component 6 is located on one side of the laser engraving component 3, and the side pushing component 7 is working.

[0073] In one specific implementation, when the laser engraving component 3 engraves a three-phase energy meter or data acquisition terminal, the lifting and positioning component 9 is activated, lifting the compatible tooling tray from the surface of the conveyor line 8 to a preset height, so that the bottom surface of the tray is detached from the conveyor line 8. Subsequently, the positioning component 6 activates the translation rodless cylinder 18, driving the downward pressing linear slide rail mounting plate 17 to move horizontally along the translation linear slide rail 16, moving the entire positioning component 6 to one side of the laser engraving component 3 to avoid interference with the three-phase energy meter or data acquisition terminal. After the positioning component 6 is in place, the side pushing component 7 is activated, and its side pushing cylinder 28 drives the side pushing aluminum plate 26 to push the side pushing buffer pad 27 inward along the direction perpendicular to the conveying direction, applying force from both sides of the conveyor line 8 simultaneously, so that the three-phase energy meter or data acquisition terminal completes the precise positioning before engraving, ensuring that the position is consistent each time it is engraved.

[0074] At this time, the laser engraving component 3 starts working under the command of the control system to mark and engrave the three-phase energy meter or data acquisition terminal that has been positioned. After the engraving is completed, the lifting and positioning component 9 descends and resets, the side pushing component 7 returns to its original position, and the positioning component 6 returns to its initial position, waiting for the next tray to enter.

[0075] Referring to Figure 3, in a specific embodiment, the positioning component 6 includes a translational linear slide rail 16, a pressing linear slide rail mounting plate 17, a translational rodless cylinder 18, a mounting plate 19, and a shim block 23. The mounting plate 19 is fixed to the profile frame component 4 by bolts, serving as a fixed base for the positioning component 6. The translational linear slide rail 16 is fixed to the mounting plate 19 by bolts, and its guide rail direction is perpendicular to the conveying direction of the conveyor line 8. The translational rodless cylinder 18 is fixed to the mounting plate 19 by bolts, and its drive end is connected to the pressing linear slide rail mounting plate 17, used to drive the pressing linear slide rail mounting plate 17 to reciprocate along the translational linear slide rail 16. The pressing linear slide rail mounting plate 17 is fixed to the slider of the translational linear slide rail 16 by the shim block 23, thereby realizing the movement of the entire positioning component 6 in a direction perpendicular to the conveyor line 8, so as to move the entire positioning component 6 out of the engraving station when processing three-phase energy meters or data acquisition terminals, avoiding interference with large-sized products.

[0076] In one specific embodiment, the positioning component 6 further includes: a horizontal positioning strip 10, a vertical positioning strip 11, a stiffening plate 12, a downward pressing fixing plate 13, a downward pressing linear slide rail 14, a downward pressing cylinder 15, and a downward pressing cylinder connector 24; the downward pressing cylinder 15 is fixed to the downward pressing linear slide rail mounting plate 17 mentioned above by bolts. As mentioned above, the downward pressing linear slide rail mounting plate 17 is indirectly connected to the mounting plate 19 through the translational linear slide rail 16. The mounting plate 19 is directly fixed to the profile frame assembly 4 by bolts, thereby indirectly connecting the downward pressing cylinder 15 to the profile frame assembly. The component 4 is connected, and the downward pressing cylinder 15 is also connected to the downward pressing fixing plate 13 through the downward pressing cylinder connector 24. The downward pressing cylinder 15 is used to drive the downward pressing fixing plate 13 downward, so that the horizontal positioning strip 10 and the vertical positioning strip 11 contact the single-phase energy meter. The horizontal positioning strip 10 is fixed to the vertical positioning strip 11, the stiffening plate 12 and the downward pressing fixing plate 13 by bolts. The downward pressing fixing plate 13 is connected to the downward pressing linear slide rail 14 by bolts. The downward pressing linear slide rail 14 is fixed to the downward pressing linear slide rail mounting plate 17 by bolts. The stiffening plate 12 is fixed to the downward pressing fixing plate 13 by bolts.

[0077] It is understandable that when the single-phase energy meter enters the engraving station along with the compatible tooling tray, the pressing cylinder 15 is activated, pulling the pressing fixing plate 13 vertically downward through the pressing cylinder connector 24. This movement is guided by the pressing linear slide rail 14 to ensure a smooth and unbiased pressing process. The guide rail of the pressing linear slide rail 14 is fixed to the pressing linear slide rail mounting plate 17, and the slider is connected to the pressing fixing plate 13. As the pressing fixing plate 13 moves downward, the horizontal positioning bar 10 and the vertical positioning bar 11, which are rigidly connected to it, move downward synchronously and contact the top and side surfaces of the single-phase energy meter, respectively, to achieve Z-axis pressing and Y-axis limiting. The horizontal positioning bar 10 is fixed to the vertical positioning bar 11, the stiffening plate 12, and the pressing fixing plate 13 by bolts to form a stable positioning frame. The stiffening plate 12 is further connected to the pressing fixing plate 13 by bolts, which effectively enhances the overall structural rigidity and prevents deformation due to force during positioning or engraving, thereby ensuring the consistency and accuracy of the engraving position.

[0078] In one specific embodiment, the positioning component 6 further includes: a hydraulic buffer 20, a proximity sensor 21, and a buffer mounting plate 22; the buffer mounting plate 22 is fixed to the mounting plate 19 by bolts; the hydraulic buffer 20 and the proximity sensor 21 are fixed to the buffer mounting plate 22 by nuts.

[0079] It is understandable that when the positioning component 6 moves along the linear slide rail 16 away from the engraving station to the end of its stroke under the drive of the rodless translation cylinder 18, the proximity sensor 21 mounted on the buffer mounting plate 22 first senses the trigger signal and feeds back the positioning information to the control system in real time to confirm that the avoidance action is completed and proceed to the next process. At the same time, the hydraulic buffer 20 synchronously absorbs the inertial impact energy at the end of the mechanism's movement, effectively mitigating mechanical collisions and ensuring that the entire translation process is smooth, quiet, and reliable, thereby extending the service life of the equipment and improving the stability of automated operation. The buffer mounting plate 22 is fixed to the mounting plate 19 with bolts to ensure that the buffer and detection elements always maintain accurate positions during vibration and repeated movements, providing the system with stable and reliable end protection and status sensing functions.

[0080] Referring to Figure 4, in a specific embodiment, the side-push assembly 7 includes: a cylinder fixing plate 25, a side-push aluminum plate 26, a side-push buffer pad 27, and a side-push cylinder 28; the side-push assembly 7 directly fixes the cylinder fixing plate 25 to the side of the conveyor line 8 with bolts, and the side-push cylinder 28 is fixed to the cylinder fixing plate 25 with bolts; the side-push aluminum plate 26 is fixed to the side-push cylinder 28 with bolts; and the side-push buffer pad 27 is fixed to the side-push aluminum plate 26 with bolts.

[0081] Understandably, when the positioning component 6 moves out of the engraving station, the side-push cylinder 28 is activated, driving the side-push aluminum plate 26 and the side-push buffer pad 27 to move horizontally. The side-push components 7 on both sides of the conveyor line contact and push the three-phase energy meter or data acquisition terminal to the preset engraving position to achieve precise positioning and provide a stable reference position for subsequent laser engraving, ensuring that the position is consistent each time it is engraved. After the engraving is completed, the side-push cylinder 28 automatically retracts, the buffer pad detaches from the surface of the three-phase energy meter or data acquisition terminal, and the compatible tooling tray continues to be conveyed forward to the verification station.

[0082] In one specific implementation, the side-push assembly 7 includes four sets, which are respectively fixed to the left and right side brackets of the conveyor line 8 by bolts. Two sets are provided on each side, and they are arranged symmetrically in front and behind.

[0083] Referring to Figure 5, in one specific embodiment, the lifting and positioning assembly 9 includes: a guide shaft 29, a lifting fixing plate 30, a positioning pin 31, a support column 32, a floating joint 33, a lifting and positioning plate 34, a linear bearing 35, and a lifting cylinder 36; the lifting fixing plate 30 is fixed to the profile frame assembly 4 by bolts; the guide shaft 29 passes through the lifting fixing plate 30 and is fixed to the lifting and positioning plate 34 by bolts; the linear bearing 35 is fixed to the lifting fixing plate 30 by bolts and sleeved on the outer periphery of the guide shaft 29; positioning... Pin 31 and support column 32 are fixed to lifting positioning plate 34 by bolts. Positioning pin 31 is used to insert into the positioning hole of compatible tooling pallet, and support column 32 is used to support compatible pallet. Lifting cylinder 36 is fixed to lifting fixing plate 30 by bolts. Floating joint 33 connects lifting positioning plate 34 and lifting cylinder 36 through its threaded hole and stud. When lifting cylinder 36 is activated, it drives lifting positioning plate 34 to move upward, so that positioning pin 31 and support column 32 lift compatible tooling pallet to preset height.

[0084] It is understood that the lifting fixing plate 30 is fixed to the bottom crossbeam of the profile frame assembly 4 by bolts, serving as the mounting base for the entire lifting positioning assembly 9; the guide shaft 29 is vertically inserted into the pre-set through hole on the lifting fixing plate 30, and its upper end is fixed to the lifting positioning plate 34 by bolts, forming a rigid connection; the linear bearing 35 is bolted to the lifting fixing plate 30 and sleeved on the outer circumference of the guide shaft 29, used to guide the lifting positioning plate 34 to slide smoothly up and down along the guide shaft 29, preventing deflection or jamming during movement; the positioning pin 31 and the support column 32 are both fixed to the upper surface of the lifting positioning plate 34 by bolts; wherein, the positioning pin 31 is a cylindrical pin, the diameter of which matches the positioning hole at the bottom of the compatible tooling pallet, used to insert into the pallet positioning hole to achieve precise positioning; The support column 32 is a cylindrical or square column structure, with its upper end face contacting the bottom surface of the pallet to provide uniform support force and prevent pallet deformation. The lifting cylinder 36 is fixed to the lower mounting surface of the lifting fixing plate 30 by bolts. The piston rod end is machined with external threads, which are connected to the internal threaded hole of the floating joint 33. The other end of the floating joint 33 is connected to the lifting positioning plate 34 through a stud to transmit thrust. When the compatible tooling pallet runs with the conveyor line 8 to the engraving station or verification station, the lifting cylinder 36 is activated by air intake, the piston rod extends, and pushes the lifting positioning plate 34 upward along the guide shaft 29 through the floating joint 33. The support column 32 lifts the bottom surface of the pallet, raising the entire compatible tooling pallet to a preset height, such as 10mm, above the surface of the conveyor line 8 to facilitate engraving or verification operations.

[0085] In one specific embodiment, please refer to Figures 1-2. The engraving and verification device for automatic compatibility with single-phase and three-phase energy meters and data acquisition terminals also includes a dust collection component 5. The dust collection component 5 is fixed to the profile frame component 4 by bolts and is located below or to the side of the laser engraving component 3. During the laser engraving process, the dust collection component 5 can suck up the dust and debris generated during engraving in real time to prevent contaminants from adhering to the surface of the energy meter or the optical lens, thereby ensuring the engraving quality and long-term stable operation of the equipment.

[0086] In one embodiment, the control conveyor line 8 transports a compatible tooling tray to the engraving station; the lifting and positioning component 9, pre-installed at the engraving station, lifts the compatible tooling tray to a preset height; when engraving a three-phase energy meter or data acquisition terminal, the control positioning component 6 moves to one side of the laser engraving component 3 to avoid interference, and controls the side pushing component 7 to position the three-phase energy meter or data acquisition terminal from both sides of the conveyor line 8; when engraving a single-phase energy meter, the control positioning component 6 positions the single-phase energy meter, and controls the side pushing component 7 to remain stationary; the control laser engraving component 3 adjusts the engraving focal length according to the meter shape and engraves the qualified markings on the energy meter; after engraving is completed, the control conveyor line 8 transports the compatible tooling tray to the verification station; the lifting and positioning component 9, pre-installed at the verification station, lifts the compatible tooling tray to a preset height; the control light source component 1 illuminates the energy meter, and the verification component 2 adjusts the imaging focal length according to the meter shape, judges the engraved markings, and uploads the judgment result.

[0087] The workflow of the engraving station is understandable: Conveyor line 8 transports a compatible tooling tray horizontally. The tray can carry single-phase energy meters, three-phase energy meters, or data acquisition terminals. When the tray reaches the engraving station, the lifting and positioning component 9 activates, lifting the tray to a preset height. When the meter type is a three-phase energy meter or data acquisition terminal: the lifting and positioning component 9 also lifts the compatible tooling tray, controlling the positioning component 6 to move laterally out of the engraving station, making room for the three-phase energy meter or data acquisition terminal and avoiding mechanical interference. The side-pushing component 7 activates, pushing the compatible tooling tray from both sides of the conveyor line to complete the positioning. When the meter type is a single-phase energy meter: the positioning component 6 presses down, and its lateral positioning... Positioning bar 10 and vertical positioning bar 11 contact the energy meter to achieve precise positioning. The laser engraving component 3 moves up and down according to the height of the meter and adjusts to a suitable focal length to engrave the energy meter. The side push component 7 does not move to avoid interference. After the laser engraving component 3 automatically adjusts the focal length according to the product height, the engraving is completed. The workflow of the verification station is as follows: After the engraving is completed, the compatible tooling tray is transported to the verification component 2 station by the conveyor line 8. The lifting and positioning component 9 moves again to lift the tray to the preset height. The light source component 1 starts to illuminate, and the verification component 2 takes pictures of the engraved mark for comparison. The verification result is automatically archived and uploaded to the production management system.

[0088] In one specific embodiment, when engraving a three-phase energy meter or data acquisition terminal, the control positioning component 6 is moved to one side of the laser engraving component 3 to avoid interference. This includes: driving the translation rodless cylinder 18 to extend its piston rod, which drives the downward linear slide rail mounting plate 17 to move horizontally along the translation linear slide rail 16, thereby moving the horizontal positioning bar 10, the vertical positioning bar 11 and the downward fixing plate 13 as a whole to one side of the laser engraving component 3 to avoid the three-phase energy meter or data acquisition terminal.
