Description

Technical Field

[0001] The invention belongs to the technical field of machine vision, and in particular relates to an adjustment device for visual detection, an adjustment method for a visual detector, and an AOI detection combination device for a slitting machine. Background Art

[0002] AOI (Automated Optical Inspection) is automatic optical inspection. The slitting machine AOI combined inspection device integrates the AOI inspection system on the basis of the slitting machine. The slitting machine is mainly used to slit wide materials (such as paper, objects to be inspected, magnetic tapes, etc.) into narrow materials. The AOI inspection part uses optical principles to capture the image of the slit product through a camera, and then uses image processing algorithms to analyze the image to detect product size, shape, surface defects and other quality-related parameters.

[0003] In the existing slitting machine AOI inspection combination device, the high-resolution camera is generally placed in a protective box. When visual inspection is required, the protective box is moved out and visual inspection is performed on the object to be inspected. If there are scratches or holes on the surface of the inspected object or the slitting size does not meet the set standards, the system can identify these defects by comparing with the standard template or the set parameter range. When necessary, it is necessary to control the rotation of the camera and change the inspection angle. The position of the camera is generally fixed. When the camera needs to be moved or the angle needs to be changed, it is necessary to manually adjust the camera position. The operation is cumbersome and it is difficult to control the position and angle of each camera after movement, resulting in low inspection accuracy.

[0004] Therefore, an adjustment device for visual inspection, a visual detector adjustment method and a slitting machine AOI inspection combination device are designed to solve the technical problem in the prior art that the detection accuracy is reduced due to manual movement of the camera position and angle.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

Other words used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.). As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0026] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." modify the entire list of elements when following a list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0027] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limited. As used herein, the singular articles "one", "an" and "the" may also be intended to include plural forms, unless it is clearly indicated above that this is not the case.

[0029] Research has found that in the existing slitting machine AOI inspection combination device, the high-resolution camera is generally placed in a protective box. When visual inspection is required, the protective box is moved out and visual inspection is performed on the object to be inspected. If there are scratches or holes on the surface of the object to be inspected, or the slitting size does not meet the set standards, the system can identify these defects by comparing with the standard template or the set parameter range. When necessary, it is necessary to control the rotation of the camera and change the inspection angle. The position of the camera is generally fixed. When the camera needs to be moved or the angle needs to be changed, the camera position needs to be manually adjusted. The operation is cumbersome and the position and angle of each camera after movement are difficult to control consistently, resulting in low inspection accuracy.

[0030] Based on the above research, the embodiments of the present disclosure provide an adjustment device for visual inspection, a visual detector adjustment method and a slitting machine AOI inspection combination device. By providing an adjustment device for visual inspection, the detection angle of the visual detector can be adjusted without the operator opening the protective box. When inspection is required, the distance adjustment mechanism is started to drive the visual detector to translate after the angle is adjusted, thereby controlling the distance between the visual detector and the object to be inspected. Compared with manual adjustment, the movement accuracy of each inspection component is improved, thereby improving the overall inspection accuracy.

[0031] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0033] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] In some embodiments, Figure 1As shown, the visual detector 3 is placed on the carrier plate 30, and the carrier plate 30 and the deflection member 46 are fixed. When the detection angle of the visual detector 3 needs to be adjusted, it is only necessary to start the rotating motor 40, and its output end drives the driving gear 41 to rotate. Since the driving gear 41 is meshed with the driven gear 42, and the control rod 43 is fixed on the upper end surface of the driven gear 42, at this time, the control rod 43 rotates following the driven gear 42. It can be seen from the figure that the center of the deflection member 46 is hollow and the control rod 43 is slidably connected to the central hollow part, and the fixed rod 45 is fixed on the bottom plate 44, passes through the central hollow part of the deflection member 46 and abuts against one end of the inner wall of the central hollow part. Therefore, with the rotation of the control rod 43, the deflection member 46 is driven to deflect around the axial direction of the fixed rod 45, thereby driving the carrier plate 30 fixed on the upper end surface of the deflection member 46 and the visual detector 3 to deflect and change the detection angle.

[0035] In some embodiments, Figure 3 As shown, when it is necessary to adjust the distance between the visual detector 3 and the object to be detected 20, the operator starts the driver 50, and its output end drives the push rod 51 to extend, and then the visual detector 3 is pushed to translate through the push rod 51, and in the process of extending the push rod 51, the piston member 53 fixed on its outer wall is driven to slide in the sleeve 52. At this time, the one-way air intake valve provided on the outer wall of the sleeve 52 is opened, and the outside air is drawn into the cavity between the driver 50 and the piston member 53. When the visual detector 3 is retracted into the detection protection box 10 after the work is completed, the push rod 51 is reset and drives the piston member 53 to reset, squeezing the previously extracted outside air into the air pipe 54, and the air is discharged from the other end of the air pipe 54 to clean the detection surface of the visual detector 3, so as to avoid the external dust from adhering to the surface of the visual detector 3 during the long-term extension of the visual detector 3 for detection, thereby affecting the subsequent detection effect.

[0036] On the other hand, a method for adjusting a visual detector is provided, comprising the following steps: Step S1, according to the detection parameter requirements of the detected object, the driver 50 is controlled to start, and the extension and retraction of the output end of the driver 50 are controlled to drive the visual detector 3 to translate, thereby changing the distance between the visual detector 3 and the detected object; Step S2, when the distance between the visual detector 3 and the detected object is adjusted, the rotary motor 40 is controlled to start, and the control rod 43 is driven to deflect left and right, thereby controlling the deflection member 46 and the orientation angle of the visual detector 3 connected to the deflection member 46.

[0037] On the third aspect, a slitting machine AOI detection combination device is provided, including a support frame 2 for an object to be detected, which is used to support and transmit the object to be detected 20, and move the detection protection box 10 to one side of the support frame 2 for the object to be detected, and align the detection protection box 10 on the support frame 2 for the object to be detected with the object to be detected. When the detection operation is required, the detection protection box 10 is opened, and the visual detector 3 inside is directed toward the object to be detected 20 for detection, and the visual detection adjustment device as described above is used below the visual detector 3.

[0038] In the description of the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, terms such as "first", "second" and other numerical terms do not imply an order or sequence when used in this document unless explicitly indicated above. Therefore, without departing from the teachings of the example embodiments, the first element, component, region, layer or section discussed above may be referred to as a second element, component, region, layer or section.

[0040] Spatially relative terms, such as "inside", "outside", "below", "below", "down", "above", "on", etc., may be used herein to facilitate description of the relationship of one element or feature to another element or feature as illustrated in the figure. In addition to the orientation depicted in the figure, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is turned over, the elements described as "below" or "below" other elements or features will be oriented to be "above" other elements or features. Therefore, the example term "below" can cover the orientation above and below. The device can be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0041] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
