[0002] With the continuous advancement of electronic technology, the application scope of PCB (printed circuit board) substrates is constantly expanding, involving many fields such as communications, computers, consumer electronics, etc. In the production process of PCB substrates, marking is an important means of identifying product information and tracing quality. Its automation and accuracy are crucial to improving product quality and production efficiency. However, the PCB substrate marking equipment currently on the market has certain deficiencies in applicability and durability.

[0003] These devices are often only applicable to specific types of PCB substrates. For substrates of different specifications or materials, the marking effect is often difficult to guarantee.

As a key component in the marking equipment, the wear problem of the conveyor belt has always plagued the use of the equipment. During long-term operation, the conveyor belt is prone to wear and deformation due to friction and wear with the PCB substrate, which in turn affects the accuracy and stability of the marking. This not only reduces the service life of the equipment, but also increases the maintenance cost and downtime of the equipment. For this reason, we propose a fully automatic laser marking device for PCB substrates. Utility Model Content

The other end of the support plate 8 is fixedly installed with the mounting plate 5. The motion component is responsible for accurately controlling the movement of the marking component in three-dimensional space, including the X-axis, the Y-axis and the Z-axis. Driven by the first motor 10, the first motor 10 drives the linkage belt 11 to rotate through the pulley. When the linkage belt 11 rotates, it drives the linkage plate 9 to move on the X-axis, and then through By extending and retracting the telescopic rod 7, the telescopic rod 7 drives the mounting plate 5 to move on the upper end of the slide rail 4 through the support plate 8 when extending and retracting, thereby realizing the movement of the marking component on the Y axis. When controlling the movement of the marking component on the Z axis, the second motor 19 is controlled to operate.

During the entire movement process, the CCD visual camera 20 plays a key role. It captures the position and shape information of the product in real time, and feeds this information back to the control box 16. The control box 16 calculates the distance and angle that the marking component needs to move based on this information, and realizes the movement of the motion component through the corresponding motor and drive device.

This flexible and precise movement capability enables the fully automatic laser marking equipment to adapt to the marking needs of different products and provide high-quality and efficient marking effects.

[0037] Working principle: First, the product is placed on the conveyor belt 13, which keeps running under the action of the driving device to smoothly transfer the product to the marking area. The bottom of the conveyor belt 13 is fixedly connected to the top of the box 1 to ensure its stable working state. At the same time, the adjustment track set at the bottom of one side of the conveyor belt 13 can be appropriately adjusted according to the size of the product to meet the transmission requirements of different products. When the product is placed on the conveyor belt 13 for transmission, the protective plate 14 can prevent the product from contacting the edge or bottom structure of the conveyor belt 13 due to deviation or falling, which can not only prevent the product from being damaged, It can also ensure that the conveyor belt will not be interrupted due to being stuck by foreign objects. In addition, the protective plate 14 can also prevent the staff from accidentally touching the running part of the conveyor belt 13 during operation, thereby protecting the safety of the staff. Then the operating component is controlled. The motion component is responsible for accurately controlling the movement of the marking component in three-dimensional space, including the X-axis, Y-axis and Z-axis. The first motor 10 drives the linkage belt 11 to rotate through the pulley. When the linkage belt 11 rotates, it drives the linkage plate 9 to move on the X-axis, and then through the extension of the telescopic rod 7, the telescopic rod 7 is extended through the support plate 8. The movable mounting plate 5 moves on the upper end of the slide rail 4, so that the marking component moves on the Y axis. When the marking component is controlled to move on the Z axis, the second motor 19 is controlled to run. When the second motor 19 runs, the second motor 19 drives the transmission wheel 21 to rotate. When the transmission wheel 21 rotates, the transmission wheel 21 is linked with the pulley at the bottom of the movable arm 12 through the linkage belt 11, so as to drive the mounting frame 15 in the marking component to move on the Z axis. In the whole moving process, the CCD visual camera 20 plays a key role. It captures the position and shape information of the product in real time, and feeds back this information to the control box 16. The control box 16 Based on this information, the distance and angle that the marking component needs to move are calculated, and the movement of the moving component is realized through the corresponding motor and drive device. After the marking component is positioned at the accurate position, the laser 17 starts to work, it emits a high-energy laser beam, which is accurately focused on the product surface through the focusing system. The rangefinder 18 monitors the distance between the laser beam and the product surface in real time to ensure that the focusing depth of the laser beam is appropriate, thereby obtaining a high-quality marking effect. This flexible and precise movement capability enables the fully automatic laser marking equipment to adapt to the marking needs of different products and provide high-quality and efficient marking effects.
