[0002] The image acquisition device of the inspection equipment is an automated device that uses an image sensor (such as a camera) to acquire image or video information of a target object, and then analyzes, measures, identifies, and judges the information through computer vision algorithms and image processing technology. Its main components include an industrial camera, lens, light source, and image acquisition card. In use, the CCD camera is fixed to the support frame and adjusted to a suitable angle. The cables connecting the CCD camera and the back-end control and processing equipment are then connected. When installing the CCD camera, rotate the adjusting rod to adjust the position of one of the clamping plates. Then, hold the CCD camera with one hand, aligning it with the side of the adjusted clamping plate, and with the other hand, rotate the other adjusting rod to clamp the CCD camera securely in place.

[0003] Traditional clamping mechanisms rely solely on mechanical pressure to fix the camera, lacking a dynamic compensation mechanism. This leads to micro-displacement due to thermal expansion and contraction or vibration after prolonged use. Therefore, there is a need to provide an image acquisition device for detection equipment to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an image acquisition device for a detection equipment, so as to solve the problems mentioned in the background art. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an image acquisition device for a detection equipment, comprising: The system includes a support frame, a U-shaped plate, clamping plates, and a CCD camera. The U-shaped plate is fixed to the upper end of the support frame, the clamping plates are fixed to the inner side of the U-shaped plate by an adjusting rod, and the CCD camera is clamped between the two clamping plates. The support assembly includes a spring column, a support plate, an inclined plate, and a rubber pad. The spring column is fixed to the side of the U-shaped plate, the side of the support plate is fixed to the movable end of the spring column, the inclined plate is fixed to the end of the support plate away from the U-shaped plate, and the rubber pad is fixed to the upper end of the support plate. The support assembly also includes openings, which are formed on both sides of the U-shaped plate, and the movable end of the spring column is inserted into the opening; The support assembly also includes a groove and a rubber wheel. The groove is formed on the side of the support plate and the inclined plate, and the rubber wheel is rotatably connected in the groove. The CCD camera has a cable connector fixed at one end, and a lens is screwed to the other end away from the cable connector. The CCD camera is placed on the upper end of the rubber pad, and the rubber wheel is attached to the outside of the lens.

[0005] Furthermore, it also includes a limiting component, which includes a movable hole and a first limiting block. The movable hole is opened at the lower end of the U-shaped plate, and one end of the first limiting block is inserted into the movable hole, while the other end is fixed to the other end of the support plate away from the inclined plate.

[0006] Furthermore, the limiting component also includes a second limiting block, which is fixed to the other end of the first limiting block away from the support plate.

[0007] Furthermore, the limiting assembly also includes a threaded groove and a connecting rod. The threaded groove is formed in the middle of the other end of the first limiting block away from the support plate. One end of the connecting rod is fixed to the side of the second limiting block, and the other end is screwed into the threaded groove.

[0008] This utility model has the following beneficial effects: This invention, through its designed support assembly, allows for easy installation of a CCD camera. The CCD camera is held in hand, and the lens is pushed between two inclined plates. As the CCD camera and lens move, the two inclined plates move in opposite directions, compressing the spring column in the opening and simultaneously rotating the rubber wheel in the groove. When the lens moves between the two support plates, the CCD camera is placed on the rubber pad above the two support plates. Then, the adjusting rod is rotated to clamp the CCD camera onto the clamping plate. This design effectively compensates for micro-displacements caused by thermal expansion and contraction or vibration through dynamic displacement compensation, while also providing support to the lower end of the CCD camera, ensuring long-term camera stability.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0014] Please see Figure 1-4 As shown, this utility model is an image acquisition device for a detection equipment, comprising: The support frame 10, U-shaped plate 11, clamping plate 12 and CCD camera 13 are provided. The U-shaped plate 11 is fixed to the upper end of the support frame 10. The clamping plate 12 is fixed to the inner side of the U-shaped plate 11 by an adjusting rod. The CCD camera 13 is clamped between the two clamping plates 12. One end of the CCD camera 13 is fixed with a cable connector, and the other end away from the cable connector is screwed with a lens 14. The support frame 10 is used to support the CCD camera 13, the U-shaped plate 11 is used to support the clamping plate 12, the adjustable slider at the upper end of the support frame 10 is locked by the locking rod, the support rod connecting the U-shaped plate 11 is inserted into the slider and is also locked by the locking rod, the clamping plate 12 is used to clamp the CCD camera 13, and the position is adjusted by the adjusting rod. The CCD camera 13 integrates a vision sensor and a light source, and transmits the signal to the back-end processing system through the cable. The lens 14 facilitates light focusing.

[0015] The support assembly includes a spring column 21, a support plate 22, an inclined plate 23, and a rubber pad 26. The spring column 21 is fixed to the side of the U-shaped plate 11, the side of the support plate 22 is fixed to the movable end of the spring column 21, the inclined plate 23 is fixed to the end of the support plate 22 away from the U-shaped plate 11, and the rubber pad 26 is fixed to the upper end of the support plate 22. The support assembly also includes openings 20, which are formed on both sides of the U-shaped plate 11, and the movable end of the spring column 21 is inserted into the openings 20; The support assembly also includes a groove 24 and a rubber wheel 25. The groove 24 is formed on the side of the support plate 22 and the inclined plate 23, and the rubber wheel 25 is rotatably connected in the groove 24. CCD camera 13 is placed on the upper end of rubber pad 26, and rubber wheel 25 is attached to the outside of lens 14; The opening 20 facilitates the insertion and fixing of the spring post 21, which has a telescopic function. The support plate 22 provides support, and the inclined plate 23 facilitates the opening of the support plate 22 when the lens 14 moves. The groove 24 is used to install the rubber wheel 25, which can reduce the frictional resistance when the lens 14 moves. The rubber pad 26 can prevent the CCD camera 13 from being worn.

[0016] Working principle: When installing the CCD camera 13, hold the CCD camera 13 and push the lens 14 between the two inclined plates 23. As the CCD camera 13 and the lens 14 move, the two inclined plates 23 move in opposite directions, which compresses the spring post 21 in the opening 20 and drives the rubber wheel 25 in the groove 24 to rotate. When the lens 14 moves between the two support plates 22, place the CCD camera 13 on the rubber pad 26 above the two support plates 22. Then rotate the adjusting rod to clamp the clamping plate 12 onto the CCD camera 13.

[0017] This step, through dynamic displacement compensation, effectively compensates for micro-displacements caused by thermal expansion and contraction or vibration, while also providing support for the lower end of the CCD camera 13, ensuring the long-term stability of the camera.

One end of the connecting rod 33 is fixed to the side of the second limiting block 34, and the other end is screwed into the threaded groove 32. The movable hole 30 facilitates the movement of the first limiting block 31, while the first limiting block 31 and the second limiting block 34 serve as limiting blocks. The threaded groove 32 and the connecting rod 33 facilitate the connection between the first limiting block 31 and the second limiting block 34.

[0019] Working principle: Insert the first limiting block 31 at one end of the support plate 22 into the movable hole 30. The side of the first limiting block 31 is fixed to the spring column 21. The connecting rod 33 on the side of the second limiting block 34 is screwed into the groove 24. Hold the CCD camera 13 and push the lens 14 between the two inclined plates 23, causing the support plate 22 to move in opposite directions. At the same time, the first limiting block 31 moves along the movable hole 30, and the second limiting block 34 moves accordingly, until the CCD camera 13 is placed on the rubber pad 26.
