Description

Technical Field

[0001] This utility model relates to the field of visual testing technology, and in particular to a CCD visual testing module. Background Technology

[0002] Visual inspection is the use of machines to replace human eyes for measurement and judgment. Visual inspection refers to the process of converting the captured target into an image signal through machine vision products, transmitting it to a dedicated image processing system, and converting it into a digital signal based on pixel distribution and information such as brightness and color.

[0003] A search revealed that patent CN219454965U proposes a portable visual testing module. This technical solution has the following problems:

[0004] The existing CCD vision testing module does not have a light source during the testing process, resulting in insufficient reflected light intensity on the surface of the object being tested, which leads to low image contrast and difficulty in distinguishing target features from the background. This is especially true for objects with similar colors or complex surface textures, where feature extraction becomes difficult.

[0005] To address the aforementioned problems, this utility model document proposes a CCD vision testing module. Utility Model Content

[0006] This invention provides a CCD vision testing module that solves the problems in the prior art where the CCD vision testing module does not have a light source during the testing process, resulting in insufficient reflected light intensity on the surface of the object being tested, leading to low image contrast and difficulty in distinguishing target features from the background. This is especially true for objects with similar colors or complex surface textures, where feature extraction becomes difficult.

[0007] This utility model provides the following technical solution:

[0008] A CCD vision testing module, comprising:

[0009] A test bench, wherein a support rod is welded to the top side of the test bench, a sliding frame is slidably fitted on the outer wall of the support rod, and a handle is welded to one side of the sliding frame;

[0010] A CCD module is fixedly installed on one side of the slide frame by screws, and locking screws are threaded inside both sides of the slide frame, which cooperate with the two sides of the support rod to lock and fix the slide frame.

[0011] The light source assembly in the visual testing process is set on the sliding frame to illuminate the surface of the object being tested.

[0012] In one possible design, the light source assembly includes a fixing block, a mounting ring, an LED ring light, a magnet, and an iron block. The fixing block is welded to the bottom side of the slide frame, the mounting ring is welded to the bottom side of the fixing block, and the LED ring light is disposed at the bottom of the mounting ring for illuminating the surface of the object to be tested placed on the test platform.

[0013] In one possible design, multiple magnets are fixedly disposed on the bottom side of the mounting ring, and multiple iron blocks are disposed on the top side of the LED ring light, with the magnets attracting the iron blocks.

[0014] In one possible design, a top plate is welded to the top of the support rod, and a receiving frame is fixed to the bottom side of the top plate by screws for storing the CCD module when it is not in use.

[0015] In one possible design, a groove is provided on the inner side of the receiving frame, and a sliding plate is slidably connected inside the groove to close the bottom of the receiving frame and form a closed receiving protection. A limit plate is welded to one side of the sliding plate.

[0016] In one possible design, one side of the support rod is provided with a dimension line corresponding to the sliding frame.

[0017] In one possible design, the bottom side of the test bench is symmetrically welded with support bases in pairs.

[0018] In this application, during use, the test platform serves as the basic support platform. The support rod welded to its top provides a vertical support structure for the entire module. The support seats welded symmetrically in pairs on the bottom side of the test platform provide stable support for the entire CCD vision test module, ensuring that the module remains stable during operation and avoiding the impact of vibration on the accuracy of test results. At the same time, the sliding frame is slidably fitted onto the outer wall of the support rod. The vertical position of the CCD module can be adjusted by sliding the sliding frame. When the CCD module is moved to the appropriate position, the locking screws connected by the internal threads on both sides of the sliding frame are rotated to make it tightly engage with both sides of the support rod, thereby locking and fixing the sliding frame and ensuring the stability of the CCD module during testing. Using the dimension line on one side of the support rod corresponding to the sliding frame, the operator can precisely control the movement distance of the sliding frame when adjusting its position, thereby achieving precise adjustment of the CCD module's position and meeting the testing height requirements of different tested objects.

[0019] In the visual testing process, the light source component plays a crucial role. The fixing block is welded to the bottom of the sliding frame, providing the mounting base for the entire light source component. The mounting ring is welded to the bottom of the fixing block to support and fix the LED ring light. Multiple magnets are fixedly set on the bottom of the mounting ring, and multiple iron blocks are set on the top of the LED ring light. Through the mutual attraction between the magnets and the iron blocks, the LED ring light can be easily installed and removed from the mounting ring. When it is necessary to illuminate the surface of the object under test, the LED ring light is turned on, and the light emitted by it is evenly illuminated on the surface of the object under test placed on the test platform, providing good lighting conditions for the CCD module, ensuring the accuracy and clarity of the visual test, avoiding low image contrast, difficulty in distinguishing target features from the background, and improving applicability. The CCD module is fixedly installed on one side of the sliding frame with screws. With the cooperation of the light source component, the CCD module can clearly acquire image information of the object under test. By controlling the shooting parameters of the CCD module, such as exposure time and gain, images of the object under test under different conditions can be obtained to meet different testing needs.

[0020] When the CCD module is not in use, a housing frame is installed to protect it from damage by the external environment. A top plate is welded to the top of the support rod, and the housing frame is fixed to the bottom side of the top plate with screws. Then, the CCD module is moved to the housing frame for storage. The inner side of the housing frame has a sliding groove, and a sliding plate is slidably connected inside the groove. When the CCD module is placed in the housing frame, the sliding plate is pushed to slide in the groove, so that the sliding plate seals the bottom of the housing frame, thus forming a closed housing protection, effectively preventing dust, debris and other objects from entering the housing frame and damaging the CCD module. A limit plate is welded to one side of the sliding plate to limit the sliding position of the sliding plate and ensure that the sliding plate can accurately seal the housing frame.

[0021] In this utility model, the CCD vision testing module, through the light source component, enables convenient installation and removal of the LED ring light on the mounting ring, which can provide good lighting conditions for the CCD module, ensure the accuracy and clarity of vision testing, and avoid low image contrast, making it difficult to distinguish target features from the background.

[0022] In this utility model, the CCD vision testing module, through the setting of structures such as sliding frame, locking screw and dimension line, can accurately control the moving distance of the sliding frame according to the dimension line, thereby realizing the precise adjustment of the position of the CCD module, meeting the testing height requirements of different tested objects, and can also lock and fix the sliding frame to ensure the stability of the CCD module position during the testing process;

[0023] This invention enables convenient installation and removal of the LED ring light on the mounting ring, and also provides good lighting conditions for the CCD module, ensuring the accuracy and clarity of visual testing, avoiding low image contrast and difficulty in distinguishing target features from the background. At the same time, it can clearly acquire image information of the object under test, and can obtain images of the object under test under different conditions to meet different testing needs.
