Description

Technical Field

[0001] This utility model relates to the field of connector manufacturing technology, specifically to a robotic automated laser engraving production line. Background Technology

[0002] In industries such as electronics manufacturing and automotive parts production, connector surfaces often require laser engraving of specifications and parameters. Traditional connector laser engraving processes have many limitations and cannot meet modern production demands.

[0003] Traditional laser engraving technology is highly dependent on manual operation, resulting in extremely low production efficiency. Manual placement, positioning, and securing of connectors are required before starting the equipment for processing; each step consumes a significant amount of time and is unsuitable for large-scale production, leading to extended product delivery cycles and impacting a company's market competitiveness.

[0004] Product quality is also unstable due to manual operation. Manual operation is subjective and uncertain; factors such as operator skill level and fatigue can affect laser engraving quality. For example, positioning deviations can lead to inaccurate pattern placement, and improper parameter adjustments can result in unsatisfactory laser engraving effects. Differences between operators can also cause inconsistent product quality, increasing defect rates and rework rates, and raising production costs.

[0005] Meanwhile, traditional processes are labor-intensive, and operators are prone to fatigue from prolonged, meticulous work, which affects efficiency and quality. Furthermore, rising labor costs mean companies need to pay higher labor expenses, and hiring more staff increases management complexity. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a robot-based automated laser engraving production line, comprising:

[0008] The feeding mechanism is provided in two sets, both of which are used to supply connectors to be laser-engraved.

[0009] A laser engraving worktable, the upper part of which is equipped with a rotary drive mechanism and a laser generator. The rotary drive mechanism is used to drive the connector to rotate during the laser engraving process, and the laser generator is used to laser engrave the connector's specifications on the surface of the connector.

[0010] An industrial robot, wherein the drive end of the industrial robot is equipped with two sets of pneumatic grippers for transferring the connector provided by the feeding mechanism to the drive end of the rotary drive mechanism.

[0011] Furthermore, a conveyor belt is installed on the upper part of the laser engraving workbench, which is used to transport the finished connectors after laser engraving.

[0012] Furthermore, the laser emitting end of the laser generator is located directly above the driving end of the rotary drive mechanism.

[0013] Furthermore, the feeding mechanism includes a feeding height adjustment mechanism, which is used to adjust the height of the connector to achieve the clamping height of the pneumatic gripper driven by the industrial robot.

[0014] Furthermore, the feeding mechanism also includes a linear drive module, which is installed on the lifting end of the feeding height adjustment mechanism and is used to transport the connector.

[0015] Furthermore, the feeding mechanism also includes a fixture mounted on the drive end of the linear drive module for accommodating and constraining the connector.

[0016] This invention provides a robotic automated laser engraving production line. Compared with existing technologies, it has the following advantages:

[0017] This robotic automated laser engraving production line uses robots to precisely grasp and transfer connectors, along with a highly automated feeding, laser engraving, and conveying process, which greatly shortens the laser engraving time for a single connector.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2This utility model provides a technical solution: a robot-based automatic laser engraving production line, mainly composed of a feeding mechanism 1, a laser engraving worktable 2, a rotary drive mechanism 3, a laser generator 4, a conveyor belt 5, and an industrial robot 6. The feeding mechanism 1 further includes a feeding height adjustment mechanism 11, a linear drive module 12, and a fixture 13. The drive end of the industrial robot 6 is equipped with two sets of pneumatic grippers 7. Specifically:

[0023] The feeding height adjustment mechanism 11 adopts an electric screw lifting device, mainly composed of a motor, screw, nut, guide rod, and other components. The motor is connected to the screw via a coupling, the nut engages with the screw, and the guide rod provides guidance and stability. When the height of the connector needs to be adjusted, the motor starts, driving the screw to rotate, and the nut moves linearly along the screw, thereby driving the lifting end of the entire feeding height adjustment mechanism 11 to rise or fall. By precisely controlling the number of rotations and direction of the motor, the connector can be accurately adjusted to the clamping height of the pneumatic gripper 7 driven by the industrial robot 6. Before the production line starts, the target height of the feeding height adjustment mechanism 11 is set through the control system according to the clamping height requirements of the industrial robot 6. After receiving the instruction, the system starts working, adjusts the connector height to the set position, and maintains stability after adjustment.

[0024] The linear drive module 12 is installed on the lifting end of the feeding height adjustment mechanism 11. The linear drive module 12 is a synchronous belt linear module, including components such as a synchronous belt, synchronous pulleys, guide rails, and sliders. The synchronous belt is wound around two synchronous pulleys, and the slider is fixed on the synchronous belt and can slide on the guide rail. The motor drives the synchronous pulleys to rotate, and the synchronous belt moves accordingly, causing the slider to perform linear reciprocating motion on the guide rail. The fixture 13 is installed on the slider to realize the delivery of the connector. When the connector height is adjusted to the correct position, the motor of the linear drive module 12 starts, driving the slider to move along the guide rail, delivering the connector on the fixture 13 to the designated position, waiting for the industrial robot 6 to grasp it.

[0025] The fixture 13 is installed on the drive end of the linear drive module 12, and the fixture 13 is custom-designed according to the external dimensions and structural characteristics of the connector. The fixture 13 has a groove that matches the connector to accommodate and constrain the connector. The connector to be laser-engraved is placed in the groove of the fixture 13. The groove matches the shape of the connector to ensure that the connector remains stable during the transport process and does not shake or shift. The operator correctly places the connector on the fixture 13, and the fixture 13 moves together with the linear drive module 12 to transport the connector to the gripping position of the industrial robot 6.

[0026] The rotary drive mechanism 3, the laser generator 4, and the conveyor belt 5 are all installed on the upper part of the laser engraving worktable 2.

[0027] The rotary drive mechanism 3 mainly includes components such as a motor, reducer, rotary shaft, and clamp. The motor is connected to the rotary shaft via the reducer, and the clamp is mounted at the end of the rotary shaft. During laser engraving, the motor starts, and after being reduced in speed by the reducer, it drives the rotary shaft to rotate, thereby rotating the connector mounted on the clamp. By precisely controlling the motor's speed and rotation angle, laser engraving of the connector at different angles can be achieved. When the industrial robot 6 places the connector on the clamp of the rotary drive mechanism 3, the clamp holds the connector. The laser engraving control system controls the rotary drive mechanism 3 to start according to the preset laser engraving pattern and parameters, causing the connector to rotate as required.

[0028] Laser generator 4 uses a fiber laser and mainly consists of a laser power supply, a laser resonant cavity, and a fiber coupler. The laser power supply provides energy to the laser resonant cavity, which generates laser light. The fiber coupler couples the laser light into an optical fiber for transmission. The laser light generated by laser generator 4 is transmitted through the optical fiber to the laser emitter, which is located directly above the drive end of the rotary drive mechanism 3. When the connector rotates under the drive of the rotary drive mechanism 3, the laser beam emitted by the laser emitter is focused on the connector surface. By controlling parameters such as laser power, pulse width, and repetition frequency, the required specifications are laser-engraved on the connector surface. During the laser engraving process, the laser engraving control system controls the laser generator 4 to start according to the preset laser engraving pattern and parameters, adjusting the relevant laser parameters so that the laser beam engraves on the connector surface according to the set path and intensity.

[0029] Conveyor belt 5 is a belt conveyor, mainly composed of a belt, drive pulley, driven pulley, motor and other components. The motor drives the drive pulley to rotate, and the drive pulley drives the driven pulley to rotate through the belt, thereby realizing the cyclical movement of the belt. After the connector has completed laser engraving, the industrial robot 6 places the connector on the conveyor belt 5 through the pneumatic gripper 7. Driven by the motor, the conveyor belt 5 transports the laser-engraved finished connector to the next process or the finished product collection area.
