Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, and in particular to a laser marking device for copper and aluminum busbars. Background Technology

[0002] In the field of electrical engineering manufacturing, such as power equipment, switchgear, and busbar trunking, copper and aluminum busbars are key conductive connection components. They are widely used in current transmission in power distribution systems due to their diverse specifications and large usage. To achieve product traceability, process management, and on-site installation identification, it is usually necessary to mark information such as numbers, specifications, phase sequence markings, QR codes, or barcodes on the surface of copper and aluminum busbars. In recent years, with the requirements of modern intelligent manufacturing for high precision, high efficiency, and traceability, laser marking technology has gradually become the mainstream means of marking metal workpieces due to its advantages such as non-contact, permanent, high precision, and strong programmability. It is widely used in the automated processing production lines of copper and aluminum busbars.

[0003] Patent CN215787612U, authorized by patent publication number CN215787612U, discloses an easy-to-use integrated laser marking machine. This device features an adjustable-height marking head structure, utilizing a servo motor to drive a lead screw that raises and lowers a sliding sleeve and control box, enabling adaptive marking of workpieces of varying heights. It also includes a display screen and rotary knob interface for easy parameter setting and equipment debugging. Furthermore, the device integrates a dust extraction system, connected to an external dust collector via a dust exhaust pipe, to extract metal fumes during marking under negative pressure, effectively improving the working environment. Its modular design also supports quick assembly and disassembly of marking components, facilitating later maintenance and repair. While possessing practicality and human-machine friendliness, some shortcomings remain in practical applications. The device lacks an automatic feeding mechanism, requiring manual placement of copper and aluminum components on the worktable. This method is not only labor-intensive and inefficient, but also suffers from discontinuous feeding cycles, easily leading to workpiece misalignment, overlapping feeding, or missed marking due to operational errors, severely impacting marking accuracy and the overall automation level of the production line.

[0004] Therefore, there is an urgent need to provide a laser marking device for copper and aluminum busbars with automatic feeding function. Utility Model Content

[0005] In order to overcome the shortcomings of existing copper and aluminum busbar laser marking equipment, such as reliance on manual feeding, low production efficiency, and uneven feeding rhythm, which affect processing efficiency, this utility model provides a copper and aluminum busbar laser marking device with automatic feeding function.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a copper-aluminum busbar laser marking device, comprising a conveyor table, a laser marking device disposed in the middle of the conveyor table, a material placement frame disposed on the right side of the conveyor table, a straight-line discharge port disposed at the lower part of the material placement frame, a fixing frame disposed at the lower part of the material placement frame, a guide rod fixedly connected to the rear side of the fixing frame, a screw parallel to the guide rod rotatably disposed on the front side of the fixing frame, a servo motor mounted on the front side of the fixing frame, the output shaft of the servo motor being fixedly connected to the screw through a coupling, a sliding plate slidably disposed on the guide rod, a threaded hole matching the screw being opened on the front side of the sliding plate to form a threaded transmission connection, a top plate fixedly connected to the left end of the sliding plate, the top plate being located inside the material placement frame.

[0007] More preferably, limit plates are provided on both the front and rear sides of the conveyor table.

[0008] More preferably, an air suction hood is provided at the top center of the limiting plate, with its opening facing the surface of the conveyor table. A three-way air pipe is provided on the air suction hood. The three-way air pipe has a Y-shaped diversion structure, with its two branch ports connected to the left and right ends of the air suction hood respectively. A purification chamber is installed on the main output port. An activated carbon plate is provided inside the purification chamber. An air pump is installed on both branch ports of the three-way air pipe connected to the air suction hood.

[0009] More preferably, the air intake hood is entirely transparent.

[0010] More preferably, a vision detector is installed in the middle of the laser marking machine, with its detection end facing the marking station below.

[0011] More preferably, an audible and visual warning light is installed in the middle of the laser marking device, and the audible and visual warning light is electrically connected to the visual detector.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting a linear motion mechanism driven by a servo motor and a screw below the placement frame, the top plate can be driven to move horizontally back and forth, and the stacked copper and aluminum bars can be pushed out one by one from bottom to top, completing stable and reliable single-piece separation and automatic feeding, effectively replacing the traditional manual feeding method, reducing the intensity of operation, avoiding the problems of missed marking, repeated marking or misalignment caused by human factors, and greatly improving the continuity and rhythm consistency of marking operation.

[0013] 2. By installing vision detectors on both sides of the conveyor, the workpiece's position can be identified in real time, triggering the marking action to ensure accurate and complete marking, eliminating missed or incorrect marking. Furthermore, the vision detectors are electrically linked with the audible and visual warning lights, automatically alarming when a workpiece is not in place, repeated feeding occurs, or marking is abnormal. This facilitates timely intervention by operators, enhances the safety of human-machine interaction, and also helps in rapid fault diagnosis and production process traceability.

[0014] 3. By integrating a transparent suction hood above the marking area and using dual air pumps for coordinated suction, efficient capture of smoke and dust at the source is achieved. The flue gas enters the multi-stage purification chamber through a three-way air pipe and passes through a primary activated carbon plate, effectively removing metal particles and harmful gases, ensuring that emissions meet industrial environmental protection and occupational health and safety requirements.

Detailed Implementation

[0022] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0023] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 A laser marking device for copper and aluminum busbars includes a conveyor table 1, a laser marking device 2 disposed in the middle of the conveyor table 1, and limit plates 3 on both the front and rear sides of the conveyor table 1 to constrain the lateral position of the copper and aluminum busbars during the conveying process, prevent deviation, and ensure accurate entry into the laser marking area. A material placement frame 4 for stacking and storing copper and aluminum busbars to be marked is disposed on the right side of the conveyor table 1. A straight-line discharge port is provided at the bottom of the material placement frame 4, the width of which is slightly greater than the thickness of a single copper or aluminum busbar but less than the height of two stacked busbars, ensuring that only the bottom busbar can pass through at a time. A fixing frame 5 is disposed at the bottom of the material placement frame 4, a guide rod 6 is fixedly connected to the rear side of the fixing frame 5, and a screw 7 parallel to the guide rod 6 is rotatably disposed on the front side of the fixing frame 5. A servo motor 8 is mounted on the front side of the fixing frame 5, and the output shaft of the servo motor 8 is fixedly connected to the screw 7 via a coupling. A sliding plate 9 is slidably disposed on the guide rod 6. A threaded hole matching the screw 7 is provided on the front side to form a threaded transmission connection, thereby constituting a linear motion mechanism driven by the servo motor 8 and the screw 7, realizing the precise reciprocating movement of the sliding plate 9 in the horizontal direction. The top plate 10 is fixed to the left end of the sliding plate 9. The top plate 10 is located inside the material placement frame 4. When the sliding plate 9 moves to the left under the drive of the servo motor 8, the top plate 10 simultaneously pushes a piece of workpiece located at the bottom of the stacked copper and aluminum bars, pushing it horizontally out of the discharge port, completing the single-piece separation and loading action. A vision detector 16 is installed in the middle of the laser marking machine 2, with its detection end facing the marking station below, for real-time monitoring of the workpiece's position and quality feedback of the marking process. Two audible and visual warning lights 17 are installed in the middle of the laser marking machine 2. The audible and visual warning lights 17 are electrically connected to the vision detector 16. When the workpiece is not in place, repeated marking, or abnormal state is detected, an alarm is automatically triggered to improve operational safety and production traceability.

[0024] In use, multiple copper and aluminum strips to be marked are neatly stacked in the placement frame and fall sequentially by their own weight. The servo motor 8 is started, driving the screw 7 to rotate, which in turn moves the sliding plate 9 and the top plate 10 horizontally to the left. The top plate 10 pushes the bottom copper and aluminum strip out of the straight discharge port, detaching it from the stacking area, thus achieving automatic feeding. The pushed-out copper and aluminum strips fall smoothly onto the surface of the conveyor table 1. The conveyor table 1 transports the workpiece to the left to the designated marking station below the laser marking machine 2. When the detector confirms that the workpiece is in place, the laser marking machine 2 starts and completes the marking according to the preset content. During the marking process, the vision detector 16 can monitor the marking quality in real time. If any abnormality is detected, such as missing parts, misalignment, or marking failure, the audible and visual warning light 17 will immediately alarm, prompting manual intervention or triggering the shutdown protection. After marking is completed, the conveyor table 1 continues to run, sending out the finished product. At the same time, the servo motor 8 drives the top plate 10 to reset, preparing for the next pushing action, thus achieving continuous automated operation.

[0025] Example 2: Based on Example 1, please refer to... Figure 5 A suction hood 11 is installed at the top center of the limiting plate 3, with its opening facing the surface of the conveyor table 1. It is used to capture metal fumes and volatile particulate matter generated during the marking process. The suction hood 11 is transparent, allowing operators to observe the workpiece running status and equipment operation in the marking area. A three-way air pipe 12 is installed on the suction hood 11. The three-way air pipe 12 has a Y-shaped diversion structure, with its two branch ports connected to the left and right ends of the suction hood 11, respectively. A purification chamber 13 is installed on the main output port. The purification chamber 13 is equipped with an activated carbon plate 14, which is used to adsorb harmful gases generated during laser processing and intercept dust, achieving multi-stage purification. Air pumps 15 are installed on both branch ports of the three-way air pipe 12 connected to the suction hood 11 to provide a negative pressure power source, so that a uniform and stable negative pressure zone is formed inside the suction hood 11, effectively sucking in the fumes generated in the marking area from both sides simultaneously, preventing pollutants from spreading into the operating space.

[0026] When the laser marking device 2 irradiates the copper and aluminum busbars with high-energy laser, the local metal is heated and vaporized, generating processing fumes containing fine metal particles and harmful gases. At this time, the air pumps 15 on both sides start synchronously, forming a negative pressure suction force in the suction hood 11. The fumes are quickly captured from the bottom opening of the hood and transported to the purification chamber 13 through the three-way air pipe 12. The fumes are then treated by primary filtration and activated carbon adsorption in the purification chamber 13, ultimately achieving standard emissions and improving the working environment.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
