Description

Technical Field

[0001] The utility model relates to the technical field related to length-fixing machines, and in particular to an adaptive automatic telescopic camera bracket anti-collision device. Background Art

[0002] In modern metallurgical manufacturing, industrial cameras installed on sizing machines play a crucial role. As high-precision cutting equipment, the core function of a sizing machine is to precisely cut raw materials to preset dimensions. To further enhance the accuracy and automation of this process, modern sizing machines are often equipped with precision measuring equipment such as industrial cameras. These cameras utilize advanced image processing technology to perform real-time alignment checks on the processed material, ensuring cutting accuracy and product consistency.

[0003] The cut-to-length machine moves according to preset dimensions to ensure that the raw material is cut to the required specifications. The camera bracket is often placed in front of the cut-to-length machine. Therefore, during the cut-to-length machine's movement, the camera and other measuring devices may accidentally collide with other equipment, such as saw blades. The consequences of such collisions are not limited to direct physical damage to the camera and other inspection equipment. They can also cause delays in the production process, increase repair costs, and even cause wider production line downtime, thereby affecting production efficiency and the company's economic benefits. Therefore, to ensure the continuity of the production process and the safety of the equipment, it is necessary to optimize the camera bracket to reduce or eliminate the possibility of such collisions, or to minimize the damage caused by collisions to the camera and other inspection equipment.

[0004] To address this issue, one existing technology involves installing a physical or electronic stopper on the end bracket of the length-cutting machine's slide. This stops or slows the camera's movement when it contacts or approaches the stopper. This technical solution physically limits the camera's range of movement, ensuring that the camera does not contact the saw baffle when moving within a safe range. However, this stopper restricts the working range of the camera and the length-cutting machine, making it impossible to adapt to the processing needs of materials of different sizes. Furthermore, physical stoppers cannot prevent collisions, and the vibrations generated when a collision with the stopper will still affect the camera's performance and accuracy.

[0005] Another existing technology mounts the camera on a bracket containing a spring. This spring compresses when subjected to external force, absorbing some of the impact energy. If the camera accidentally contacts a saw baffle or other equipment due to the movement of the sizing machine, the spring bracket allows the camera to move backward or sideways, reducing damage from direct impact. However, if the spring's rebound force is insufficient or damaged after a collision, the camera will not be able to accurately return to the intended position, affecting subsequent operational accuracy. Furthermore, after prolonged use, the spring may fatigue, reducing its buffering effectiveness and requiring regular inspection and replacement.

[0006] Another existing technology involves installing a limit switch on the track along which the camera holder moves. When the limit switch is pressed, the system's asynchronous subroutine is activated, limiting the camera holder's movement speed to a low speed and stopping it within a specified time, thereby preventing the camera holder on the length-cutting machine from colliding with other objects. However, this solution cannot flexibly adapt to sudden changes in the production process or varying operating conditions. For example, if a temporary object blocks the camera holder and the limit switch is not reached, the system cannot be triggered. Furthermore, this technical solution still limits the operating range of the camera and the length-cutting machine. Utility Model Content

The linear slide 4 can be made of high-strength and wear-resistant materials to ensure that it is not easily worn and deformed during long-term use. The length and width of the linear slide 4 can be adjusted and customized according to the size and moving range of the sizing machine to ensure that it completely covers the moving track of the movable plate 6.
