Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a machine vision detection device. Background Technology

[0002] Visual inspection is the use of machines to replace human eyes for measurement and judgment. It involves using machine vision products to convert the captured target into image signals, which are then transmitted to a dedicated image processing system. Based on pixel distribution and information such as brightness and color, the signals are converted into digital signals. The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment based on the judgment results. It is a valuable mechanism for production, assembly, or packaging, and it has immeasurable value in detecting defects and preventing defective products from being delivered to consumers.

[0003] Existing visual inspection devices generally have limited detection angles when in use, and can only detect one side of an object or one angle of an object. The detection of objects is not comprehensive enough and the practicality is poor.

[0004] Therefore, it is necessary to provide a machine vision inspection device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a machine vision inspection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The adjustment module includes a square plate, which is fixedly connected to the support frame. A motor is fixedly connected to one side of the square plate, and the output shaft of the motor passes through the square plate. A square sleeve is fixedly connected to the end of the output shaft of the motor. A square guide rod is provided inside the square sleeve. One side of the square guide rod is hinged to the middle of the connecting plate by a pin. Slide rods are fixedly connected to both ends of the connecting plate. The slide rods are set in an L-shaped slide groove plate, which is fixedly connected to the support frame. A machine vision camera is fixedly connected to one end of the slide rod.

[0009] The rotating module includes a square plate two, which is fixedly connected to the lower side of the support frame. A motor two is fixedly connected to one side of the square plate two. The output shaft of the motor two passes through the square plate two. The end of the output shaft of the motor two is fixedly connected to the central shaft of one end of a worm gear. The worm gear meshes with a worm wheel. The central shaft of the worm wheel passes through and is movably connected to the middle of the support frame. The central shaft of the worm wheel is fixedly connected to the lower center of a circular placement platform. Angle rulers are fixedly provided on the outer side of the circular placement platform.

[0010] Preferably, the controller is fixedly connected to the upper side of the support frame.

[0011] Preferably, the indicator is fixedly connected to the upper side of the support frame.

[0012] Preferably, the indicator points to the angle ruler.

[0013] Preferably, the upper side of the circular placement platform is provided with a set of circles with the same center but different diameters.

[0014] Compared with related technologies, the beneficial effects of this utility model are:

[0015] 1. By rotating the module, the circular platform rotates the angle ruler and the object. Observe the direction of the indicator. When the indicator points to the required value, rotate the object to the angle to be detected, and control the machine vision camera to start. The machine vision camera will detect the detection point on the top of the object. When it is necessary to detect the side of the object, the adjustment module will move the slide bar to move the machine vision camera along the top of the object to the side of the object, so that the machine vision camera can detect the side of the object. This device is easy to operate and can detect objects from different angles and directions. It is highly practical.

[0016] 2. The upper side of the circular placement platform is provided with a set of circles with the same center but different diameters, so that different sized test objects can be quickly placed in the middle of the circular placement platform with the circles as a reference.

The output shaft of the motor 14 passes through the square plate 18. A square sleeve 15 is fixedly connected to the end of the output shaft of the motor 14. A square guide rod 16 is provided inside the square sleeve 15. One side of the square guide rod 16 is hinged to the middle of the connecting plate 19 by a pin. Slide rods 11 are fixedly connected to both ends of the connecting plate 19. The slide rods 11 are set in an L-shaped slide plate 17, which is fixedly connected to the support frame 3. A machine vision camera 12 is fixedly connected to one end of the slide rod 11.

[0033] The rotating module 5 includes a square plate 55, which is fixedly connected to the lower side of the support frame 3. A motor 56 is fixedly connected to one side of the square plate 55. The output shaft of the motor 56 passes through the square plate 55. The end of the output shaft of the motor 56 is fixedly connected to the central shaft of one end of a worm gear 54. The worm gear 54 meshes with a worm wheel 53. The central shaft of the worm wheel 53 passes through and is movably connected to the middle of the support frame 3. The central shaft of the worm wheel 53 is fixedly connected to the lower center of a circular placement platform 52. Angle rulers 51 are fixedly provided on the outer side of the circular placement platform 52.

[0034] The controller 2 is fixedly connected to the upper side of the support frame 3.

[0035] The indicator 4 is fixedly connected to the upper side of the support frame 3.

[0036] The indicator 4 points to the angle ruler 51.

[0038] Working principle: When an object needs to be inspected, the object is first placed on the circular platform 52. The controller 2 controls the motor 2 56 to start. The motor 2 56 drives the worm gear 54 to rotate. The worm gear 54 meshes with the worm wheel 53 to rotate. The worm wheel 53 drives the circular platform 52 to rotate, causing the circular platform 52 to drive the angle ruler 51 and the object to rotate. Observe the direction of the indicator 4.

[0041] Beneficial effects: By rotating module 5, the circular placement platform 52 drives the angle ruler 51 and the object to rotate. Observe the direction of the indicator 4. When the indicator 4 points to the required value, rotate the object to the angle to be detected, control the machine vision camera 12 to start, and detect the detection point on the upper side of the object. When it is necessary to detect the side of the object, by adjusting module 1, the slide bar 11 drives the machine vision camera 12 to move along the upper side of the object to the side of the object, so that the machine vision camera 12 can detect the side of the object. This device is easy to operate and can realize the detection of objects at different angles and in different directions, and has strong practicality.
