Description

Technical Field

[0001] The utility model relates to the technical field of CCD size and 3D line scanning detection and fixing, in particular to a CCD size and 3D line scanning detection device. Background Art

[0002] 3D line scan detection equipment, also known as 3D laser scanner or 3D line scan measuring instrument, is a device that uses laser or structured light technology to obtain three-dimensional data of the surface of an object. It uses 3D scanning technology and 2D image processing technology, through high-precision sensors and advanced optical systems, to obtain three-dimensional and two-dimensional images of the product, and perform data processing and analysis to achieve automatic detection and identification.

[0003] According to the Chinese patent CN202021240499.0, in this application, the lifting and lowering of the lifting plate is controlled by the first motor, and the rotation of the rotating bracket is controlled by the second motor. After the adjustment is completed, the line scan camera and the linear light source are aimed at the notebook shell for shooting, which can accurately and effectively shoot the corners on the notebook shell, ensuring the efficiency and accuracy of the shooting, which is convenient and practical;

[0004] Although the lifting plate in the application can effectively deal with the problem of inaccurate shooting, when in use, since the CCD size and 3D line scan detection equipment is fixed with a vacuum adsorption fixture base, the vacuum adsorption method relies on the air pressure difference to generate the adsorption force. Due to air pressure fluctuations, equipment wear or improper operation, the adsorption force of the vacuum adsorption may be unstable. When the adsorption force is weakened or lost, the notebook shell may be displaced or tilted during the detection process, resulting in inaccurate measurement data. For this reason, we propose a CCD size and 3D line scan detection equipment. Utility Model Content

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a CCD size and 3D line scan detection device, which has the following beneficial effects:

[0019] 1. The CCD size and 3D line scan detection equipment is equipped with an anti-slip structure.

[0020] 2. The CCD size and 3D line scan detection equipment is provided with a bidirectional clamping structure. When the bidirectional clamping block is in operation, the bidirectional clamping block moves toward the vacuum adsorption jig base.

Due to air pressure fluctuations, equipment wear or improper operation, the adsorption force of the vacuum adsorption may be unstable, resulting in inaccurate measurement data. The bidirectional clamping structure provides additional fixing force for the notebook shell, further improving the stability during the detection process. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The bidirectional clamping structure is arranged on the outside of the vacuum adsorption jig base 3, and is used for secondary fixing of the notebook shell. The notebook shell is placed on the vacuum adsorption jig base 3 and is initially fixed by vacuum adsorption technology.

[0029] Furthermore, the anti-slip structure includes a limiting block 13 and an anti-slip block 25. The limiting block 13 is movably connected to one side of the vacuum adsorption jig base 3. The bottom of the limiting block 13 is fixedly connected to the top of the sheet metal frame 1. Four groups of anti-slip blocks 25 are fixedly connected to the top of the vacuum adsorption jig base 3. The limiting block 13 is located on one side of the vacuum adsorption jig base 3, and its bottom is fixedly connected to the top of the sheet metal frame 1, thereby forming a barrier to prevent the notebook shell from sliding horizontally. The anti-slip block 25 is directly fixed to the top of the vacuum adsorption jig base 3, increasing the roughness of the contact surface with the notebook shell, thereby increasing the friction and preventing sliding or movement during the detection process.

[0032] Furthermore, one end of the power block 17 is movably connected to a trapezoidal movable block 18, the outer side of the trapezoidal movable block 18 is clamped together with the inner wall of the trapezoidal slide 14, and the power block 17 pushes the trapezoidal movable block 18 to slide in the trapezoidal slide 14 during movement.

[0033] Furthermore, the bottom of the trapezoidal movable block 18 is fixedly connected to a connecting block 22, the outer side of the connecting block 22 is fixedly connected to a first spring 23, the other end of the first spring 23 is fixedly connected to one side of the auxiliary block 7, and when the power block 17 moves, it will drive the first spring 23 to move synchronously.

[0034] Furthermore, the bidirectional clamping structure includes a bidirectional clamping block 19, a second fixed shaft 20, a placement groove 21 and a second spring 24.

When one end of the two-way clamping block 19 contacts the outer side of the vacuum adsorption jig base 3, the second spring 24 is squeezed, so that the other end of the two-way clamping block 19 moves downward until it contacts the notebook shell, thereby clamping the two sides of the notebook shell. When the handle 16 is released, the elastic force of the first spring 23 and the second spring 24 pushes the trapezoidal movable block 18 and the two-way clamping block 19 back to the initial position, loosening the clamping of the notebook shell.

When the power block 17 moves, it will drive the first spring 23 to move synchronously. At the same time, the two-way clamping block 19 on the inner wall of the placement groove 21 also moves synchronously, so that the two-way clamping block 19 moves toward the vacuum adsorption jig base 3. When one end of the two-way clamping block 19 contacts the outer side of the vacuum adsorption jig base 3, the second spring 24 is squeezed, so that the other end of the two-way clamping block 19 moves downward until it contacts the notebook shell, thereby clamping the two sides of the notebook shell. When the handle 16 is released, the elastic force of the first spring 23 and the second spring 24 pushes the trapezoidal movable block 18 and the two-way clamping block 19 back to the initial position, loosening the clamping of the notebook shell.
