The worktable has a mounting slot for placing the CCD module, and the side wall of the mounting slot has a through imaging channel. The lens of the CCD module faces the imaging channel. The testing control chip is electrically connected to both the test probe and the power supply. The test probe is used to connect to the test interface of the CCD module. The test probe is located at the output end of the driving mechanism, which drives the test probe to reciprocate along a first direction to connect or disconnect from the test interface. The image board is mounted on the base and faces the imaging channel, with a preset distance between the image board and the CCD module. This invention enables imaging detection of CCD modules and lens dirt detection.

[0004] The inventors discovered the following problems in their daily work when using the CCD detection module: the light source is fixed to the moving plate with several screws, making disassembly and assembly cumbersome; the distance between the light source and the CCD lens module is not easy to adjust; and the distance between the lens and the light source cannot be adjusted according to the requirements and surface characteristics of the object to be measured, resulting in poor image acquisition quality and detection effect.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 4 The present invention provides a CCD motion detection module, comprising: a frame 1 and an adjustment structure 6. A motion module 2 is mounted on the upper end of the frame 1. A motion plate 3 is mounted on the output end of the motion module 2. A CCD lens module 4 is mounted on the side of the motion plate 3 away from the frame 1. A light source 5 is mounted on the side of the motion plate 3 close to the CCD lens module 4 by means of the adjustment structure 6. The adjustment structure 6 is provided on the surface of the motion plate 3.

[0031] In the embodiments of this utility model, please refer to Figures 2 to 4The adjustment structure 6 includes an adjustment groove 601, which is formed on the movable plate 3. An adjustment rod 602 is rotatably connected to the inner wall of the adjustment groove 601. A support plate 603 is threadedly connected to the arc surface of the adjustment rod 602. The support plate 603 is slidably connected to the inner wall of the adjustment groove 601. A limit rod 604 is fixedly connected to the inner wall of the adjustment groove 601. The surface of the limit rod 604 is slidably connected to the support plate 603. Two mounting grooves 606 are formed on the surface of the support plate 603. Mounting plates 607 are slidably connected to the inner walls of both mounting grooves 606. The side of the mounting plate 607 away from the movable plate 3 is fixedly connected to the light source 5. Mounting plates 607 are slidably connected to the inner walls of the support plate 603 at positions corresponding to the two mounting grooves 606. Two positioning rods 609 are provided, with their arc surfaces slidably connected to the mounting plate 607. A connecting plate 610 is fixedly connected to the end of the positioning rod 609 furthest from the support plate 603. Two sliding grooves 611 are formed on the surface of the support plate 603, symmetrically distributed centrally. A sliding rod 612 is slidably connected to the inner wall of each groove 611. One end of the sliding rod 612 is fixedly connected to the connecting plate 610, and a spring 613 is fitted onto the arc surface of the sliding rod 612. Both ends of the spring 613 are fixedly connected to the inner walls of the sliding rod 612 and the groove 611, respectively. The light source 5 can be fixed to the support plate 603 using the mounting plate 607, making assembly and disassembly simple and convenient. The position of the support plate 603 is adjustable, facilitating the adjustment of the light source 5. The distance between the support plate 603 and the CCD lens module 4 is adjusted to obtain the best image quality and detection effect. A scale 605 is provided on the surface of the limiting rod 604, which can be used to determine the position and movement distance of the support plate 603. A guide block 608 is fixedly connected to the side of the mounting plate 607 near the support plate 603. The guide block 608 is conical in shape and assists the mounting plate 607 in sliding into the mounting groove 606. A handle 614 is rotatably connected to the side of the connecting plate 610 away from the positioning rod 609. The handle 614 has a U-shaped cross-section. Operating the handle 614 moves the connecting plate 610, facilitating user movement of the connecting plate 610. The positioning rod... The end of the positioning rod 609 away from the connecting plate 610 is arc-shaped, which facilitates the positioning rod 609 sliding into the mounting plate 607. Several pulleys 615 are rotatably connected to the four sides of the support plate 603. The pulleys 615 are slidably connected to the inner wall of the adjustment groove 601. The pulleys 615 reduce the friction between the support plate 603 and the inner wall of the adjustment groove 601, making the support plate 603 move more smoothly along the inner wall of the adjustment groove 601. Several anti-slip protrusions are fixedly connected to the lower end of the adjustment rod 602. The anti-slip protrusions are evenly distributed on the adjustment rod 602. The anti-slip protrusions increase the friction at the lower end of the adjustment rod 602, making it easier for the user to rotate the adjustment rod 602.

[0032] The working principle of the CCD motion detection module provided by this utility model is as follows: By setting the adjustment structure 6, the connecting plate 610 is first moved away from the support plate 603. The connecting plate 610 drives the positioning rod 609 to slide away from the inner wall area of ​​the mounting groove 606. The connecting plate 610 then drives the sliding rod 612 to move along the sliding groove 611. The spring 613 is in a compressed state. Then, the two mounting plates 607 on the light source 5 are moved closer to the support plate 603, so that the mounting plates 607 slide into the mounting groove 606. Then, the connecting plate 610 is released. The spring 613 in the compressed state gives the sliding rod 612 an elastic force in the opposite direction. The sliding rod 612 drives the connecting plate 610 closer to the support plate 603. The connecting plate 610 then drives the positioning rod 609 to slide into the mounting plate 607 in the mounting groove 606, so that the position of the mounting plate 607 is fixed, thereby fixing the light source 5 on the support plate 603. Then, the adjustment rod 602 is rotated. The adjustment rod 602 uses a threaded belt to... The moving support plate 603 moves, during which it moves up or down along the limiting rod 604 and the adjusting groove 601. The support plate 603 drives the light source 5 to move up or away from the CCD lens module 4 via the mounting plate 607. The position and moving distance of the support plate 603 can be determined by referring to the scale 605. The guide block 608 assists the mounting plate 607 to slide into the mounting groove 606. The operating handle 614 drives the connecting plate 610 to move, making it easier for the user to move the connecting plate 610. The end of the positioning rod 609 away from the connecting plate 610 is arc-shaped, making it easier for the positioning rod 609 to slide into the mounting plate 607. The pulley 615 reduces the friction between the support plate 603 and the inner wall of the adjusting groove 601, making the support plate 603 move more smoothly along the inner wall of the adjusting groove 601. The anti-slip protrusion increases the friction at the lower end of the adjusting rod 602, making it easier for the user to rotate the adjusting rod 602.
