Description

Technical Field

The CCD camera visual detection device includes a light source system, a lens system, a CCD sensor, an image processing unit, and a control system. The light source system provides illumination to ensure clear image acquisition, while the lens system is responsible for focusing and forming the workpiece image. The core CCD sensor converts the optical signal into an electrical signal, which, after being processed by the image processing unit, generates a digital image and performs further feature analysis and judgment; as disclosed in the authorization announcement number CN220569058U, a new type of CCD image detection light source device includes a base, a first support column is provided on the right side of the top of the base, and a lifting mechanism is provided inside the first support column.

When in use, the first threaded rod drives the second support column to move up and down, the second support column drives the strip plate to move up and down, and the strip plate drives the CCD body to move up and down, which plays a role in adjusting the shooting focal length. A clamping mechanism is installed. When in use, the second electric telescopic rod drives the clamping plate to clamp the object to be photographed, and the third motor drives the clamping plate to rotate, which plays a role in rotating the object to facilitate photographing the bottom surface of the object, and can adjust the height of the CCD camera.

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5 The utility model provides an embodiment: a novel CCD image detection device, comprising four columns 1 and an H-shaped top plate 2 fixed at the top of the four columns 1, U-shaped slides 3 are slidably installed on both sides of the interior of the H-shaped top plate 2, and right-angle plates 4 are installed on both sides of the top of the U-shaped slide 3, a hollow shell 5 is fixed between the two right-angle plates 4, an electric tilting mechanism 6 is provided inside the hollow shell 5, a CCD industrial camera 7 is installed on the movable end of the electric tilting mechanism 6, a screw rod bidirectional distance adjustment module 8 arranged parallel to the H-shaped top plate 2 is installed on one side of the top of the H-shaped top plate 2, and the movable end of the screw rod bidirectional distance adjustment module 8 is fixedly connected to the outer wall of one side of the right-angle plate 4;

[0019] The U-shaped slide 3 and the right-angle plate 4 are both made of stainless steel. A rectangular slide is provided on both sides of the top of the H-shaped top plate 2. A protruding arm is slidably installed inside the rectangular slide. One end of the protruding arm is fixedly connected to the outer wall of one side of the U-shaped slide 3. A protruding arm is installed on the outer wall of the side of the U-shaped slide 3 close to the central axis of the H-shaped top plate 2. The U-shaped slide 3 maintains a stable sliding connection with the H-shaped top plate 2 through the protruding arm.

[0020] The screw rod bidirectional distance adjustment module 8 includes a hollow straight frame installed on the top of the H-shaped top plate 2, a bidirectional screw rod rotatably installed inside the hollow straight frame, a nut pair installed at the threads at both ends of the surface of the bidirectional screw rod, and a servo motor installed on the outer wall of one side of the hollow straight frame for driving the bidirectional screw rod to rotate. The outer wall of one side of the nut pair is fixedly connected to the outer wall of one side of the right-angle plate 4. When controlling the distance between the two CCD industrial cameras 7, the staff drives the two U-shaped slides 3 and the right-angle plate 4 to move closer to or away from each other through the screw rod bidirectional distance adjustment module 8. The servo motor, bidirectional screw rod, nut pair and other components inside the screw rod bidirectional distance adjustment module 8 ensure the accuracy and stability of the camera distance adjustment, and reduce the influence of mechanical vibration or wear on the detection accuracy;

[0021] The electric tilting mechanism 6 includes an upper support shaft 601 fixed to one end of the interior of the hollow shell 5, an electric push rod 602 hingedly mounted on one end of the surface of the upper support shaft 601, and a V-shaped bending seat 603 hingedly mounted on the other end of the interior of the hollow shell 5. The top end of the V-shaped bending seat 603 and the bottom end of the piston rod of the electric push rod 602 are hinged to each other. A support member is installed on the outer wall of one side of the V-shaped bending seat 603. The V-shaped bending seat 603 is connected to the CCD industrial camera 7 through the support member. The support member is a T-shaped frame 604 mounted on the outer wall of one side of the V-shaped bending seat 603 and an L-shaped downturn 605 mounted on the outer wall of one side of the T-shaped frame 604. The CCD industrial camera 7 is mounted on the top wall of the L-shaped downturn 605.

[0022] When controlling the angle of the CCD industrial camera 7, the electric tilting mechanism 6 changes the flipping angle of the V-shaped bending seat 603 by the extension length of the electric push rod 602, thereby adjusting the angle between the lens of the CCD industrial camera 7 and the vertical plane. The electric control simplifies the operation process, reduces the operating requirements for the operator, realizes the precise adjustment of the shooting angle, and reduces the errors and inconveniences that may be caused by manual adjustment.

[0023] When the embodiment of the present application is in use, the staff first arranges the device on two parallel and synchronous workpiece production lines, and starts the screw rod bidirectional distance adjustment module 8 to work, and the screw rod bidirectional distance adjustment module 8 drives the two symmetrical U-shaped slides 3 to move toward each other, that is, the two U-shaped slides 3 move away from or close to each other, thereby adjusting the horizontal suspended position of the CCD industrial camera 7 on the workpiece production line until the shooting field of the CCD industrial camera 7 roughly coincides with the workpiece transferred on the workpiece production line. Then the staff starts the electric tilting mechanism 6 to work, and each electric tilting mechanism 6 independently controls the shooting of the workpiece by the CCD industrial camera 7. Image angle, so that the CCD industrial camera 7 captures the image of the workpiece at a suitable and optimal viewing angle, reduces the impact of adverse factors such as shadows and reflections on the image quality, and thus improves the detection accuracy. The detection device allows the detection of two workpieces at the same time, is suitable for the mode of parallel production of multiple assembly lines, improves the detection efficiency of the device, and realizes the adjustment of the camera spacing and independent control of the shooting angle through structures such as the U-shaped slide 3, the screw rod and screw rod two-way distance adjustment module 8 and the electric tilting mechanism 6, thereby ensuring that all key parts of the detected workpiece are clearly and accurately photographed, avoiding detection blind spots and improving the comprehensiveness of detection.
