Description

Technical Field

[0001] This utility model relates to the field of automated welding technology, and in particular to a CCD camera anti-vibration bracket for weld seam tracking. Background Technology

[0002] In automated welding operations, the weld seam tracking system is one of the core components to ensure welding quality and efficiency. The CCD camera, as the system's visual sensor, must be stably and accurately mounted on the welding equipment to acquire weld seam images in real time and accurately. Currently, the common installation method is to use a bracket made of a metal connecting plate to rigidly fix the CCD camera to the side of the welding equipment.

[0003] However, the welding environment itself is a strong source of vibration. These vibrations mainly come from the following aspects: First, the vibration of the welding equipment itself, including the inertial impact generated by the servo motor that drives the welding torch during start-up, shutdown, and speed changes; second, the vibration generated by the welding process itself, especially in gas metal arc welding, the periodic, high-frequency mechanical impact generated when the molten wire droplets transition to the molten pool, as well as the unstable force of the arc plasma flow on the workpiece; all of the above vibrations are transmitted to the camera mounting point through the equipment structure. Therefore, using a traditional rigid plate bracket can easily allow vibrations from the equipment to be directly transmitted to the CCD camera without loss, thus affecting the CCD camera's data acquisition. Utility Model Content

[0004] (a) Technical problems to be solved In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a CCD camera anti-vibration bracket for weld seam tracking, which solves the technical problem that the traditional rigid plate bracket can easily transmit vibrations from the equipment directly to the CCD camera without loss, thereby affecting the acquisition of the CCD camera.

[0005] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by this utility model include: This utility model provides a shockproof bracket for a CCD camera used for weld seam tracking.

Both absorbing pads a and b are elastically designed to absorb and reduce the vibration force generated during the operation of the welding equipment.

[0008] Optionally, the absorbent element also includes; A flat pad is located below the absorbent pad b and is adhered to the surface of the bracket body. The flat pad is the main contact component with the camera body and is used to extend the vibration reduction path.

[0009] Optionally, the absorbent element also includes: A padding layer is located behind the absorbent pad a and between the absorbent pad a and the welding equipment. The padding layer is made of silicone and is used to initially absorb vibration.

[0010] Optionally, the absorbent pad a and the absorbent pad b are respectively provided with a fitting groove and a fitting block on opposite sides, which are matched with each other to assist personnel in assembly.

In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0018] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0019] like Figure 1-5As shown, this embodiment proposes a CCD camera anti-vibration bracket for weld seam tracking, including: a bracket body 100 and a camera body 300 disposed on its side. The bracket body 100 is made of metal sheet by bending or machining. The bracket body 100 is used to support and fix the camera body 300. A bolt 400 is provided on one side of the bracket body 100 for fastening the entire bracket body 100 to the mounting surface of welding equipment such as welding robot or gantry. Seismic resistant component 200 is disposed at the connection between the support body 100 and the welding equipment; The seismic component 200 includes an absorber disposed on the surface of the support body 100, an enclosing member sleeved on the surface of the bolt 400 disposed inside the absorber, and a compensating member that cooperates with the enclosing member to enhance the vibration blocking effect. like Figure 4 As shown, the absorbent component in this embodiment includes: absorbent pad a210 and absorbent pad b211. Absorbent pad a210 and absorbent pad b211 are designed opposite to each other and are disposed on the upper end of the surface of the support body 100. Bolt 400 is inserted between absorbent pad a210 and absorbent pad b211 and connected to the welding equipment. Absorbent pad a210 and absorbent pad b211 are both elastically designed to absorb and reduce the vibration force generated during the operation of the welding equipment. Absorption pads a210 and b211 are both made of high-damping polyurethane elastic material and are positioned on the upper part of the mounting end of the bracket body 100. When vibration is transmitted through the bolt 400 and the mounting surface, absorption pads a210 and b211 absorb and weaken most of the low- and medium-frequency vibration energy through their own elastic deformation. Furthermore, the absorbent also includes: a pad 213, which is located behind the absorbent pad a210 and between the absorbent pad a210 and the welding equipment. The pad 213 is made of silicone and is used to initially absorb vibration. The pad 213 is located behind the absorption pad a210 (i.e. the side in contact with the welding equipment) and is made of silicone. As the direct contact layer with the vibration source, it can initially absorb high-frequency vibrations and is the first absorption component of the entire shockproof unit. The absorbent also includes a flat pad 216, which is located below the absorbent pad b211 and is bonded to the surface of the bracket body 100. The flat pad 216 is the main contact part with the camera body 300 and is used to extend the vibration reduction path. The flat pad 216 is usually made of soft rubber or foam. As the main contact component with the camera body 300, it further extends and consumes the transmission path of vibration energy through the damping characteristics of its material, preventing residual vibration from acting directly on the camera body 300. The absorbent pads a210 and b211 are respectively provided with a mating groove 214 and a mating block 215 on opposite sides, which are matched with each other to assist personnel in assembly. like Figure 4 , 5 As shown, the wrapping component in this embodiment includes: wrapping ring 212. Two sets of wrapping ring 212 are provided and are respectively located on the opposite side of the absorbent pad a210 and the absorbent pad b211. The two sets of wrapping ring 212 are integrally connected to the absorbent pad a210 and the absorbent pad b211, and both are flexible designs, used to wrap the bolt 400 to reduce vibration transmission. Two sets of wrapping rings 212 are provided, which are made in one piece with the absorption pads a210 and b211 using an injection molding process, ensuring the reliability and sealing of the connection. The wrapping rings 212 are flexible and tightly wrap the shank of the bolt 400 on the inside, effectively establishing a flexible interface between the bolt 400 and the support body, significantly reducing the vibration force directly transmitted through the bolt 400. like Figure 5 As shown, the compensation component in this embodiment includes: absorption holes 217, which are provided in two sets, with each set containing at least three holes. The two sets of absorption holes 217 are respectively opened in the absorption pads a210 and b211. The absorption holes 217 are elliptical and have a through-type design. The compensation component also includes: a textured part 218, which is provided on the inner wall of the absorption holes 217 and is composed of several silicone bumps for consuming the transmission of vibration energy. When the vibration force is transmitted to the absorption hole 217, the hole changes the propagation path of the vibration force in the elastic cavity, which can cause vibration scattering and thus consume its energy; when the airflow or micro-vibration acts in the hole, the above-mentioned protrusions can effectively dissipate the vibration kinetic energy through friction, further dissipating energy. In actual operation, the vibration generated during welding equipment operation is initially absorbed by the silicone pad layer 213. Subsequently, the vibration energy is transmitted to the absorption pads a210 and b211 through the bolt 400 and mounting surface. As the main buffer components, the absorption pads a210 and b211 can absorb most of the energy through deformation due to their elastic properties. The absorption holes 217 and textured parts 218 inside consume the vibration through structural damping and friction. At the same time, the flexible wrapping ring 212 ensures that the vibration of the bolt 400 is isolated. Finally, any residual vibration that may be transmitted to the camera body 300 will be attenuated by the flat pad 216 in the final stage. Thus, an extremely stable working platform is provided for the CCD camera, ensuring the clarity of the weld seam tracking image and the stable operation of the system.
