Description
Technical Field
The utility model relates to a coiling detection device based on contact image sensor.
Background
In recent years, with the reversal of new energy industry, more and more winding and rewinding machines are used for the production of lithium batteries. Along with the improvement of the requirement on the productivity, the integration degree of the winding machine and the rewinding machine is higher and higher. The detection requirements for products and appearance are becoming more and more stringent. Meanwhile, the space reserved for the visual inspection equipment is gradually reduced. The visual system designer has to complete the system design in a smaller space. The positions of the lens, the camera and the light source are reasonably set. The suitability of conventional visual imaging solutions to meet agency requirements while avoiding potential adverse factors such as vibration, interference with other operations in the field, maintainability, etc., is greatly challenged.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in view of the above problems, a winding detection device based on a contact image sensor is provided.
The utility model adopts the technical proposal that: a rolling detection device based on a contact image sensor is characterized by comprising:
a contact image sensor for acquiring image data of an object to be inspected;
the light source corresponds to the position of the contact image sensor and is used for improving the contrast of the detected object at the position of the contact image sensor;
the image acquisition control module is used for controlling or acquiring the motion condition of the detected object so as to synchronize the exposure of the contact image sensor;
and the image processing module is used for acquiring the image data acquired by the contact image sensor and analyzing the image data to obtain the defect information of the detected object.
The image acquisition control module is electrically connected with a controller of the winding and rewinding machine for controlling the motion state of the detected object on the winding and rewinding machine.
The image acquisition control module is electrically connected with a motion state acquisition unit for acquiring the motion state of the detected object.
The motion state acquisition unit is provided with an encoder.
The utility model has the advantages that: the utility model discloses a contact image sensor cooperation image acquisition control module acquires the image data who is examined the object to carry out the analysis through image processing module and examined the defect of object.
The utility model discloses a contact image sensor acquires image data, is applicable to the detection of the continuous production product in narrow and small space, and the extremely short working distance of contact image sensor provides very big flexibility for the system, avoids compressing working distance in the traditional scheme and probably bringing serious image quality decline, the decline of maintainability (like the scheme of the folding light path of mirror, the scheme of the high distortion camera lens of short focal length). Due to the fact that the contact type image sensor is short in working distance, the requirement for light source brightness is lowered, and meanwhile accuracy and stability can be better guaranteed for the optical scheme of type coaxial illumination. Because of the smaller working distance of the contact image sensor, the imaging and light source can be integrated into one mechanism, and the device is more suitable for the requirements of production, manufacture, adjustment and calibration, simple assembly and replacement in field application and has better maintainability.
