Description

Technical Field

[0001] This utility model relates to the field of woodworking machining center positioning technology, specifically a woodworking machining center positioning and guiding device. Background Technology

[0002] In woodworking, the positioning and guiding of the boards are key to ensuring processing accuracy and efficiency. Positioning and guiding devices can ensure that the boards maintain the correct position and orientation during processing, avoiding processing errors caused by offset or shaking.

[0003] According to the patent application published on the Internet, a positioning and guiding device for a woodworking machining center (authorization announcement CN 222609909U) is described as follows: "A positioning and guiding device for a woodworking machining center includes a first fixing block, a second fixing block, a baffle, a camera assembly, and a laser ranging assembly. The baffle has two first fixing blocks arranged along its longitudinal axis. A camera assembly is provided at the bottom of the middle of each of the two first fixing blocks. A second fixing block is connected to the middle of the two first fixing blocks."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, the laser ranging component moves along the longitudinal axis of the second fixed block through the slot, and the laser rangefinder on the laser ranging component can rotate left and right. The laser irradiation emitted by the laser rangefinder meets the width requirements of the conveyor belt. When the wood is completely placed on the conveyor belt, the camera component transmits the captured data to the first control panel. After receiving and processing the data, the first control panel obtains the size and center position of the wood to be processed. However, in actual use, the device is transported by the conveyor belt, and because the size and width of the wood are different, the wood is prone to deviation during the actual transport process due to friction, which can affect the size and center position of the wood in subsequent positioning and processing. Therefore, it is necessary to improve a woodworking processing center positioning and guiding device. Utility Model Content

The specific model is SICK OD2000. Firstly, before the timber is conveyed, the positioning conveying mechanism 5, by starting servo motor 512, drives the adjusting frame 513 to rotate. During this rotation, the adjusting frame 513 drives connecting column 514 and connecting column 518 to move, which in turn drives connecting rod 515 and connecting rod 519 to move. This, in turn, drives positioning plate 517 and positioning plate 5110 to move relative to each other, allowing the device to adjust the conveying width according to the timber width. Then, the timber is placed on the trapezoidal toothed synchronous belt 523. Subsequently, by starting servo motor 521, the servo motor 52... 1. The trapezoidal toothed belt 522 rotates, and during the rotation of the trapezoidal toothed belt 522, the trapezoidal toothed synchronous belt 523 is driven to transport the wood to the device. Then, through the set ranging mechanism 3, the servo motor 32 is started, and the servo motor 32 drives the trapezoidal screw 33 to rotate. The trapezoidal screw 33 drives the moving block 34 to move, so that the moving block 34 moves along the guide post 36, thereby driving the laser ranging device 35 to move left and right, and then starting the laser ranging device 35 to measure the distance. The camera 4 transmits the captured data to the controller, which processes the data to obtain the size and center position of the wood to be processed. After receiving the data, the servo motor 521 stops running.
