[0051] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0052] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0053] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0054] In industrial manufacturing, inner hole detection is a necessary step to ensure product quality. In the case of a larger inner hole or when it is visually accessible, a preliminary inspection of the inner hole can be performed manually. However, the visual inspection method is relatively rough and cannot well guarantee the uniform production quality of the product. For this reason, there are some relatively simple inner hole detection systems in the prior art, which have compatibility disclosures and can only detect some specific product models, and the detection types are limited. In addition, this type of automated equipment has large space limitations and is not suitable for inspecting larger objects. Therefore, the prior art lacks an automated inner hole detection device with high compatibility and accuracy.

[0055] In order to at least solve the above-mentioned problems, an embodiment of the present application provides an inner hole visual inspection device, which can automatically switch the measured surface of the workpiece to ensure that the inner hole of each measured surface is automatically inspected, has high compatibility, can efficiently inspect more complex and irregular products, reduces the uncertainty of manual inspection based on experience, and improves product production efficiency.

[0056] The technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application.

[0057] Figures 1 to 3 The structure diagram of the inner hole visual inspection device described in the embodiment of the present application is shown as follows: Figures 1 to 3 As shown, the inner hole visual inspection device includes a rotating platform 11, an image acquisition component 12 and a moving component 13;

[0058] The image acquisition component 12 is connected to the moving component 13 so that the image acquisition component 12 enters the inner hole of a measured surface of the workpiece 2 to be inspected, and the image acquisition component 12 rotates in the inner hole of the measured surface to acquire multi-angle images of the inner hole; and

[0059] The workpiece 2 to be inspected is placed on the rotating platform 11, and the rotating platform 11 enables the workpiece 2 to switch the inspected surface, so that the image acquisition component 12 collects multi-angle images of the inner holes of each inspected surface of the workpiece 2 to perform visual inspection.

[0060] For further information, please refer to Figures 1 to 3 As shown, the moving component 13 includes a three-way moving module 131 and a rotating moving module 132; the image acquisition component 12 includes an industrial camera 121 and an endoscope 122; the rotating moving module 132 is respectively connected to the three-way moving module 131 and the industrial camera 121; the industrial camera 121 is connected to the endoscope 122.

[0061] Among them, since the three-way moving module 131 is connected to the rotation moving module 132, the three-way moving module 131 drives the industrial camera 121 to perform linear motion in three directions through the rotation moving module 132, so that the industrial camera 121 moves to the top of the inner hole of the measured surface, and the endoscope 122 enters the inner hole. In addition, the rotation moving module 132 causes the endoscope 122 to rotate in the inner hole to collect multi-angle images.

[0062] Among them, the three directions are perpendicular to each other.

[0063] For further information, please refer to Figures 1 to 3 As shown, the three-direction moving module 131 includes a first direction moving unit 131Y, a second direction moving unit 131X, and a third direction moving unit 131Z.

[0064] Among them, the first direction moving unit 131Y is parallel to the rotating platform 11 to provide movement in the first direction, the second direction moving unit 131X is parallel to the rotating platform 11 and perpendicular to the first direction moving unit 131Y to provide movement in the second direction, and the third direction moving unit 131Z is perpendicular to the second direction moving unit 131X to provide movement in the third direction.

[0065] Among them, the second direction moving unit 131X is connected to the first direction moving unit 131Y so that the second direction moving unit 131X can move along the first direction, the third direction moving unit 131Z is connected to the second direction moving unit 131X so that the third direction moving unit 131Z can move along the second direction, and the rotation moving module 132 is connected to the third direction moving unit 131Z so that the rotation moving module 132 can move along the third direction.

[0066] In some embodiments, the first direction moving unit 131Y is a Y-axis servo module, the second direction moving unit 131X is an X-axis servo module, the third direction moving unit 131Z is a Z-axis servo module, and the rotation moving module 132 is an R-axis servo module. The first direction moving unit 131Y, the second direction moving unit 131X, the third direction moving unit 131Z and the rotation moving module 132 can all be driven by a driving motor.

[0067] Then, when the workpiece 2 to be inspected is placed on the rotating platform 11, since the rotating moving module 132 is connected to the image acquisition component 12, the rotating moving module 132 can actually be controlled by the first direction moving unit 131Y and the second direction moving unit 131X to drive the image acquisition component 12 to move freely along the X direction and the Y direction until it reaches the top of the workpiece 2 to be inspected, and then the image acquisition component 12 is lowered to a specified position by the third direction moving unit 131Z, at which time the endoscope 122 should enter the inner hole of the inspected surface. Afterwards, the image acquisition component 12 (endoscope 122) is controlled to rotate by the rotating moving module 132, so that the endoscope 122 rotates 360 degrees in the inner hole to take pictures, so as to collect multi-angle images.

[0068] Furthermore, since the rotating platform 11 can rotate, the workpiece 2 to be inspected placed on the rotating platform 11 can also switch the inspected surface by rotation, so that the inner hole of each inspected surface can be captured with multi-angle images, thereby ensuring that the inner holes on each surface of the workpiece 2 to be inspected can be inspected, effectively ensuring the quality of the workpiece.

[0069] For further information, please refer to Figures 1 to 3 As shown, the image acquisition component 12 includes a flexible cold light source 123, and the flexible cold light source 13 provides an illumination light source for the inner hole of the measured surface, so that the industrial camera 121 can capture the inner hole image more clearly.

[0070] Furthermore, the device also includes a control unit; the control unit selects detection parameters according to the number of the workpiece 2 to be detected, and obtains visual detection results based on the image captured by the image acquisition component 12 and the detection parameters; and the control unit splices and stores the images captured by the image acquisition component 12.

[0071] Specifically, the control unit splices the multi-angle images of the inner hole of each tested surface of the workpiece 2 to be tested, and names and stores them as "SN+date".

[0072] For details, please refer to Figure 1 As shown, the rotating platform 11 has a barcode scanner 111, and the barcode scanner 121 can read the number of the workpiece 2 to be inspected and transmit it to the control unit, and the control unit obtains the corresponding detection parameters according to the received number. In some embodiments, the detection parameters of each type of product can be preset in advance. For example, the detection parameters can be set to the inner wall processing detection of the hole (scratches, burrs, dirt, etc.), the assembly effect detection of the sealing ring in the hole (missing, inverted, damaged, improperly installed, wrong model, etc. of the sealing ring), and the inner wall grease detection of the hole (the presence or absence of grease, uniformity, etc.), thereby achieving fixed detection of the inner hole of each type of product to ensure uniform product quality standards.

[0073] Therefore, the inner hole visual inspection device provided in the embodiment of the present application can automatically switch the measured surface of the workpiece to ensure that the inner hole of each measured surface is automatically inspected. It has high compatibility and can efficiently inspect more complex and irregular products, reducing the uncertainty of manual inspection based on experience and improving product production efficiency.

[0074] The following embodiments of the present application provide a method for visual inspection of inner holes, which can be applied to Figures 1 to 3 The inner hole visual inspection device shown. Figure 4 The flowchart of the inner hole visual inspection method described in the embodiment of the present application is shown as follows: Figure 4 As shown, the inner hole visual inspection method includes steps S1 to S4.

[0075] S1. Selecting detection parameters based on the serial number of the workpiece to be detected.

[0076] Specifically, the code number of the workpiece to be inspected can be obtained through a barcode scanner, and the corresponding inspection parameters preset in advance can be obtained according to the code number. In fact, the inspection parameters of each type of product can be set in advance as needed to achieve unified inspection standards.

[0077] S2. Control the moving component to make the image acquisition component enter the inner hole of a measured surface of the workpiece to be inspected, and make the image acquisition component rotate in the inner hole of the measured surface to acquire multi-angle images of the inner hole.

[0078] Specifically, as described above, the moving assembly includes a three-way moving module and a rotation moving module, the three-way moving module includes a first direction moving unit, a second direction moving unit, and a third direction moving unit, and the three directions are perpendicular to each other.

[0079] In some embodiments, the three-way moving module can be used to drive the rotating moving module and the image acquisition group to move freely along the X direction and the Y direction until they reach the top of the workpiece to be inspected, and then the image acquisition component is lowered to a specified position by the third-way moving unit, at which time the endoscope of the image acquisition component should enter the inner hole of the surface to be inspected. After that, the rotating moving module is used to control the endoscope to rotate, so that the endoscope rotates 360 degrees in the inner hole to take pictures, so as to collect multi-angle images.

[0080] S3, controlling the rotating platform to rotate so that the workpiece to be inspected switches the inspected surface, so that the image acquisition component collects multi-angle images of the inner holes of each inspected surface of the workpiece to be inspected.

[0081] Furthermore, since the workpiece to be inspected is placed on the rotating platform, the workpiece to be inspected can be rotated when the rotating platform rotates, thereby switching the inspected surface. Then, each time the image acquisition component acquires multi-angle images of the inner hole of a inspected surface, the rotating platform is controlled to rotate to switch the inspected surface, thereby achieving that the inner hole of each inspected surface can be captured with multi-angle images.

[0082] S4. Obtaining visual inspection results of the workpiece to be inspected based on the inspection parameters and the multi-angle images of the inner holes of the inspected surfaces.

[0083] Specifically, the multi-angle images corresponding to the inner holes of each measured surface are input into the visual inspection model, and the visual inspection model performs visual inspection on all the multi-angle images based on the preset inspection parameters to obtain the visual inspection result of the workpiece to be inspected.

[0084] In some embodiments, the workpiece to be inspected has n inspected surfaces, namely n1, n2, n3, etc., then multi-angle images, i.e., multiple images at different angles, are first collected for the inner hole of the n1 surface. After the collection is completed, the image of n2 is collected again until the inner holes of the n inspected surfaces are collected. All multi-angle images collected from the n inspected surfaces are input into the visual inspection model, and the visual inspection model performs visual inspection on all the multi-angle images based on the inspection parameters to obtain the inspection results corresponding to all the images, and obtains the visual inspection results of the workpiece to be inspected based on the inspection results of all the images. That is, the multi-angle images of the inner holes of each inspected surface are input into the visual inspection model, and the visual inspection model performs visual inspection on each image, outputs and records the inspection results and corresponding pictures of each image, and then determines whether the workpiece is qualified based on the inspection results of all the images.

[0085] Furthermore, after obtaining the visual inspection result of the workpiece, the multi-angle images of the inner hole of each tested surface of the workpiece to be inspected are spliced, and named and stored as "SN+date".

[0086] Figure 5 The flowchart of the inner hole visual inspection method provided by the embodiment of the present application is shown. Figure 5 As shown, the workpiece to be inspected is placed on the rotating platform and then the execution begins. The number of the workpiece to be inspected is obtained, and the corresponding inspection parameters are selected based on this. After that, multi-angle images of the inner holes of all the inspected surfaces are collected and input into the visual inspection model. The visual inspection model detects each image, outputs and records the inspection results and corresponding pictures of each image. Based on this, the inspection results of all images are comprehensively judged. When there is a certain inspection result that does not meet the inspection parameters, the workpiece is unqualified. On the contrary, if all images meet the inspection parameters, it means that the inner holes on all the inspected surfaces of the workpiece meet the inspection parameters and the workpiece is qualified. After obtaining the visual inspection results, all images are spliced ​​and named and stored as "SN+date".

[0087] It should be noted that the visual detection model can be an existing image detection model or a visual platform, etc., and this application does not impose any restrictions on this.
