The function of the four bearings 203 is to allow the four screw rods 304 in the moving mechanism 3 to rotate smoothly on the support plate 201 while reducing friction and wear. Feeding holes 204 are opened at the upper inner centers of the two support plates 201 to facilitate the placement and removal of the automobile side trim strips or other components to be tested.

[0031] As an implementation method in this embodiment, Figure 5-Figure 6As shown, the moving mechanism 3 includes four outer frames 301 and four screw rods 304. The four outer frames 301 are respectively fixedly connected between eight mutually horizontally opposed ear pieces 202. The two ends of the four screw rods 304 are respectively fixedly sleeved on the inner rings of eight horizontally opposed bearings 203. The inner centers of the four outer frames 301 are provided with slideways 302. The inner walls of the four slideways 302 are provided with slide grooves 303. The translation mechanism 4 includes four sliding sleeves 401. The four sliding sleeves 401 are respectively threadedly sleeved on the outer sides of the four screw rods 304. The four sliding sleeves 401 are respectively connected to the four slideways 302 by mutually adapted sliding sleeves. Both sides of the four sliding sleeves 401 are fixedly connected There are slide rails 402, and the eight slide rails 402 are respectively connected with the eight slide grooves 303 by mutually adapting sliding sleeves. The four slide sleeves 401 are fixedly connected with mounting rings 403. The four outer frames 301 are respectively fixedly connected between the eight horizontally opposite ear pieces 202. This design enables the moving mechanism 3 to be stably fixed on the supporting mechanism 2. The bearings 203 inside the outer frame 301 allow the screw rod 304 to rotate smoothly. The four screw rods 304 are fixed in the moving mechanism 3 through the bearings 203 at both ends. The slide sleeve 401 is threadedly sleeved on the outside of the screw rod 304. When the screw rod 304 rotates, the slide sleeve 401 will move along the thread of the screw rod 304. The slideway 302 provided at the inner center of the outer frame 301 provides a guide for the movement of the slide sleeve 401. The slide grooves 303 provided on the two inner walls of the slideway 302 are adapted to the slide rails 402 fixed on both sides of the slide sleeve 401 for sliding sleeve connection, which ensures the stability and accuracy of the slide sleeve 401 during movement. A mounting ring 403 is fixedly connected between the four slide sleeves 401, and a scanning mechanism 7 is mounted on the mounting ring 403.

The outer frame 301, the screw rod 304, the sleeve 401 and other components all adopt a modular design, which is convenient for maintenance and reduces the maintenance cost and difficulty.

[0032] As an implementation method in this embodiment, Figure 8As shown, the transmission mechanism 6 includes four first transmission wheels 601, and the four first transmission wheels 601 are respectively fixedly connected to one end of the four screw rods 304, and two first transmission wheels 601 on one side and two first transmission wheels 601 on the other side are sleeved with two first transmission belts 602 on the outer side, and the two first transmission wheels 601 at the lower side are fixedly connected to the second transmission wheels 603 on one side, and the second transmission belts 604 are sleeved on the outer side of the two second transmission wheels 603, and one side of one of the second transmission wheels 603 is fixedly connected to the output end of the driving motor 5. When one of the first transmission wheels 601 rotates, the transmission of the first transmission belt 602 makes the other first transmission wheels 601 on the same side also rotate synchronously, thereby driving the screw rods 304 connected to them to rotate, and when the driving motor 5 is started, it will drive the second transmission wheels connected thereto. The wheel 603 rotates, and the second transmission belt 604 transmits the power to the other second transmission wheel 603, and the driving motor 5 transmits the power to the two first transmission wheels 601 at the bottom through the second transmission belt 604 and the second transmission wheel 603.

By adjusting the transmission ratio of the transmission mechanism 6 and the rotation speed of the driving motor 5, it can adapt to the detection requirements of different speeds and translation distances, thereby improving the versatility and flexibility of the device. The components of the transmission mechanism 6 are all modularly designed, which is convenient for maintenance and greatly reduces the maintenance cost and difficulty.

[0033] As an implementation method in this embodiment, Fig. 9As shown, the scanning mechanism 7 includes a conductive slip ring 701, which is fixedly sleeved inside the mounting ring 403, and a plurality of laser scanners 702 are arranged in a ring and fixedly connected to the output end of the conductive slip ring 701. The conductive slip ring 701 is fixedly sleeved inside the mounting ring 403, and serves as a bridge for data transmission and power supply. Since the mounting ring 403 moves with the movement of the translation mechanism 4, the conductive slip ring 701 can ensure stable communication and data transmission between the laser scanner 702 and the control system during the movement. The plurality of laser scanners 702 are arranged in a ring and fixedly connected to the output end of the conductive slip ring 701. This layout enables the laser scanner 702 to cover a wider scanning area and reduce the scanning blind area. The laser scanner 702 measures the distance and shape of the surface of the object to be measured by emitting a laser beam and receiving a reflected signal, thereby constructing a When the translation mechanism 4 moves under the drive of the transmission mechanism 6, the mounting ring 403 and the conductive slip ring 701 and the laser scanner 702 inside it will also move synchronously. The laser scanner 702 continuously emits laser beams and receives reflected signals. The data processing system analyzes these data to achieve high-precision scanning and measurement of the object to be measured. Through the circular arrangement and synchronous operation of multiple laser scanners 702, the scanning mechanism 7 can achieve all-round and high-precision scanning of the object to be measured, ensuring the accuracy and reliability of the detection results. The control system controls the movement of the translation mechanism 4 and the scanning parameters of the laser scanner 702, which can easily realize automatic detection and data processing, thereby improving the detection efficiency.

[0034] Working principle: When in use, insert the automobile side trim strip assembly from the feeding hole 204 and place it on the placement plate 205. After completing the above steps, start the drive motor 5 through the control panel 8. The drive motor 5 transmits power to the two first transmission wheels 601 at the bottom through the second transmission belt 604 and the second transmission wheel 603. The two first transmission wheels 601 then transmit power to the other two first transmission wheels 601 on the same side through their respective first transmission belts 602, and finally the four screw rods 304 rotate synchronously, driving the four sleeves 401 to move in the four slideways 302. When the four sleeves 401 move, they will also drive the mounting ring 403 fixedly connected with the conductive slip ring 701 to move. When the conductive slip ring 701 moves, it will also synchronously drive the multiple laser scanners 702 to rotate. The multiple laser scanners 702 are arranged in a ring and fixed. Connected to the output end of the conductive slip ring 701, this layout enables the laser scanner 702 to cover a wider scanning area and reduce the scanning blind area. The laser scanner 702 measures the distance and shape of the surface of the object to be measured by emitting laser beams and receiving reflected signals, thereby building a three-dimensional model or performing tasks such as dimension measurement. The laser scanner 702 continuously emits laser beams and receives reflected signals, and analyzes these data through the data processing system to achieve high-precision scanning and measurement of the object to be measured. Through the circular arrangement and synchronous operation of multiple laser scanners 702, the scanning mechanism 7 can achieve all-round and high-precision scanning of the object to be measured, ensuring the accuracy and reliability of the detection results. By controlling the movement of the translation mechanism 4 and the scanning parameters of the laser scanner 702 through the control system, automatic detection and data processing can be easily achieved, thereby improving the detection efficiency.
