Description

Technical Field

[0001] This invention relates to the field of workpiece production quality inspection technology, and in particular to a multi-workpiece continuous inspection device based on image recognition. Background Technology

[0002] In the industrial field, there are various types of workpiece structures, such as tubular structures, block structures, and plate structures. In order to control the quality of these workpieces, the quality inspection stage during processing requires human intervention or the use of certain instruments or tools to observe, measure, and evaluate these workpieces in order to determine their quality.

[0003] To better control the quality of these structures, existing technologies typically employ image capture, recognition, and data analysis to determine the quality of these workpieces. For example, the port location of the pipe is first photographed, the pipe diameter is calculated based on the acquired image, and the paint color and gradient pattern of the pipe are simulated and analyzed by recognizing the captured image, thereby determining whether it meets the quality inspection standards according to preset criteria.

[0004] To better accomplish this process, the key is how to quickly and in batches acquire images of the workpieces, and how to obtain high-quality images. However, current technologies employ the method of photographing each workpiece individually. This method of acquiring workpiece images is not only inefficient, but also suffers from variable workpiece positions during the shooting process due to the lack of standardized workpiece placement and shooting environment. This affects the annotation of image acquisition, leading to larger relative errors, reduced image recognition efficiency, and decreased comparability between workpieces, ultimately reducing workpiece production efficiency. Summary of the Invention

[0005] This invention provides a multi-workpiece continuous inspection device based on image recognition, which solves the technical problems of existing workpiece inspection equipment being unable to guarantee the consistency of the inspection status of each workpiece, resulting in reduced comparability between workpieces, increased difficulty in image recognition, and reduced production efficiency due to larger errors.

[0006] To address the above technical problems, this invention provides a multi-workpiece continuous detection device based on image recognition, comprising an operating table and a clamping module, a rotation drive module, an image acquisition module, and a main control module mounted on the operating table; the rotation drive module is mounted at the center of the operating table, and the image acquisition module is mounted at the acquisition end of the rotation drive module; the clamping module includes multiple clamping components, which are uniformly mounted around the periphery of the rotation drive module;

[0007] The main control module is used to control the clamping module, rotation drive module, and image acquisition module to acquire images of the workpiece to be inspected according to a preset process.

[0008] The clamping module is used to fix the workpiece to be inspected and control the workpiece to switch the corresponding pose for image acquisition.

[0009] The rotation drive module is used to respond to the control of the main control module and move the image acquisition module to the corresponding stopping position;

[0010] The image acquisition module is used to acquire images of the workpiece to be inspected.

[0011] This basic solution includes a clamping module, a rotary drive module, and an image acquisition module that are connected to the main control module. It establishes an automated image acquisition mechanism, using the power of the rotary drive module to drive the image acquisition module to rotate in the axial direction and stop at different positions in sequence to acquire images of the workpiece to be inspected, which is fixed on the clamping component. By keeping the image acquisition position of the workpiece to be inspected stationary, stable continuous image acquisition of multiple workpieces is achieved, reducing shooting errors and thus improving the inspection efficiency of the product.

[0012] In a further embodiment, the rotation drive module includes a fixed body and a drive assembly. The fixed body is fixed to the operating table, and the drive assembly is mounted on the fixed body. The drive assembly includes a drive motor, a transmission structure, and a support structure. The drive motor is mounted on the back of the operating table, the transmission structure is axially connected to the drive motor, the support structure is movably mounted at the end of the transmission structure, and the image acquisition module is fixedly mounted on the support structure.

[0013] When the drive motor rotates, it will drive the transmission structure and the support structure to rotate in the horizontal direction, and drive the image acquisition module to move closer to or away from the workpiece to be inspected.

[0014] In a further embodiment, the transmission structure includes a rotating rod, a connecting ring, a sleeve, a sliding block, a telescopic spring, and a driving rod connected in sequence. The rotating rod passes through the fixed body and is mounted on the rotating shaft of the drive motor. The connecting ring is sleeved on the upper part of the rotating rod. The sleeve is fixed on the connecting ring and has an open sliding groove at one end. One end of the sliding block is embedded in the sliding groove and connected to the inner end wall of the sleeve through the telescopic spring. The other end is fixed with the downwardly mounted driving rod and connected to the support structure.

[0015] When the drive motor rotates, it drives the rotating rod to rotate and the sleeve fixed on the rotating rod to rotate. When the sleeve rotates, the driving rod is subjected to the pressure of the fixed body, which pushes the sliding block to slide inward or outward, thereby driving the support structure to perform telescopic movement along the axial direction.

[0016] This solution incorporates a transmission structure that utilizes the horizontal rotational power of a drive motor to rotate the support structure and image acquisition module axially. The pressure between the drive rod and the fixed body causes the sliding block to slide inwards or outwards, protruding or retracting the image acquisition module horizontally. This ensures that as the image acquisition module rotates to the next stopping position, the distance between it and the workpiece to be inspected gradually decreases, achieving focal length positioning for image acquisition and further improving image acquisition efficiency.

[0017] In a further embodiment, the support structure includes a central main structure, a first plate extending outward, and a second plate extending inward. The first plate is a 7-shaped plate structure, with its top horizontal position inner side connected to the transmission structure and the image acquisition module fixed on its outer side. The second plate is an inwardly extending strip-shaped support portion, which is fixed above the platform of the fixed body.

[0018] This design includes a central main structure, a first plate extending outwards, and a supporting structure for a second plate extending inwards. The image acquisition module is installed on the first plate, and the image acquisition module on the first plate is supported by the vertical relationship between the main structure and the operating table. The engagement of the second plate with the fixed body can further improve the stability of the image acquisition module in the horizontal direction.

[0019] In a further embodiment, the fixing body includes a frustum prism mounted on the operating table and a fixing ring fixed on the frustum prism; the fixing ring includes a supporting column, at least two sets of supporting plates and a guide ring, the supporting column is fixed to the center of the frustum prism, the supporting plates are radially and uniformly installed on the supporting column, and their ends are raised upward and connected to the outer edge of the guide ring.

[0020] In a further embodiment, the cross-section of the frustum prism is a regular hexagonal or regular octagonal structure, with its edges gradually contracting upwards from bottom to top; the guide ring is a regular hexagonal or regular octagonal ring structure.

[0021] This solution uses a frustum-shaped column as a fixed base and a corresponding regular polygonal guide ring. Based on communication control, it further utilizes the recesses on the edges to create mechanical positioning, which can more accurately position the image acquisition module at the work station, thereby effectively improving the accuracy of image acquisition.

[0022] In a further embodiment, the clamping component includes a vertical plate, a clamping structure, and a rotary motor. The vertical plate is vertically installed on the edge of the operating table, corresponding one-to-one with the corner of the guide ring. The clamping structure is fixed to the inner side of the vertical plate, and the rotary motor is fixed to the outer side of the vertical plate. The clamping structure is axially connected to the rotary motor.

[0023] When the rotary motor rotates, it will drive the clamping structure to rotate in the vertical direction, thereby driving the workpiece to be inspected to rotate.

[0024] In a further embodiment, the clamping structure includes a base and a plurality of limiting blocks. The base is disc-shaped with a pre-reserved mounting position in its center. The plurality of limiting blocks are radially installed around the mounting position. Each limiting block includes a fixing block fixed to the base and a slider movably installed on the fixing block.

[0025] Based on the limitations of image capture in the testing environment, this solution sets up a corresponding rotary motor for each clamping component, enabling the image acquisition module to obtain multi-angle images of the workpiece to be inspected. By utilizing the combination of a fixed block and a slider movably mounted on the fixed block, it can be compatible with various models of workpieces to be inspected, thus improving the compatibility of the equipment.

[0026] The image acquisition module includes a telescopic structure and an image capture device. The telescopic structure is fixed on the first plate, and the image capture device is installed on the movable end of the telescopic structure.

[0027] To facilitate multi-angle image acquisition of the workpiece under inspection, this solution incorporates a telescopic structure that allows the image capture device to be further transported to the target shooting position (e.g., inside a hollow workpiece under inspection) to complete image acquisition.

[0028] In a further embodiment, the operating table is a circular operating table, with a mounting through hole in the middle for mounting the rotary drive module. Attached Figure Description

[0036] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. The embodiments are given for illustrative purposes only and should not be construed as limiting the present invention. The accompanying drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of the present invention, because many changes can be made to the present invention without departing from the spirit and scope of the present invention.

[0037] This invention provides a multi-workpiece continuous detection device based on image recognition, such as... Figures 1-6 As shown, in this embodiment, the system includes an operating table 1 and a clamping module 2, a rotation drive module 3, an image acquisition module 4, and a main control module mounted on the operating table 1. The rotation drive module 3 is mounted at the center of the operating table 1, and the image acquisition module 4 is mounted at the acquisition end of the rotation drive module 3. The clamping module 2 includes multiple clamping components, which are evenly mounted around the periphery of the rotation drive module 3.

[0038] The main control module is used to control the clamping module 2, the rotation drive module 3, and the image acquisition module 4 to acquire images of the workpiece 5 to be inspected according to the preset process; the main control module includes, but is not limited to, devices with data processing functions such as control computers and control chips (MCUs).

[0039] The clamping module 2 is used to fix the workpiece 5 to be inspected and control the workpiece 5 to switch the corresponding pose for image acquisition.

[0040] The rotation drive module 3 is used to respond to the control of the main control module and move the image acquisition module 4 to the corresponding dwell position;

[0041] Image acquisition module 4 is used to acquire images of the workpiece 5 to be inspected.

[0042] In this embodiment, the rotation drive module 3 includes a fixed body 31 and a drive assembly 32. The fixed body 31 is fixed on the operating table 1, and the drive assembly 32 is mounted on the fixed body 31. The drive assembly 32 includes a drive motor 321, a transmission structure 322, and a support structure 323. The drive motor 321 is mounted on the back of the operating table 1, the transmission structure 322 is axially connected to the drive motor 321, the support structure 323 is movably mounted at the end of the transmission structure 322, and the image acquisition module 4 is fixedly mounted on the support structure 323 (i.e., the acquisition end).

[0043] When the drive motor 321 rotates, it will drive the transmission structure 322 and the support structure 323 to rotate in the horizontal direction, and drive the image acquisition module 4 to move closer to or away from the workpiece 5 to be inspected.

[0044] In this embodiment, the transmission structure 322 includes a rotating rod d, a connecting ring e, a sleeve f, a sliding block g, a telescopic spring h, and a driving rod i connected in sequence. The rotating rod d passes through the fixing body 31 and is mounted on the rotating shaft of the drive motor 321. The connecting ring e is sleeved on the upper part of the rotating rod d. The sleeve f is fixed on the connecting ring e and has an open sliding groove at one end. One end of the sliding block g is embedded in the sliding groove and is connected to the inner end wall of the sleeve f through the telescopic spring h. The other end is fixed with a downwardly mounted driving rod i and is connected to the support structure 323.

[0045] In this structure, the sliding block g is connected to one end of the telescopic spring h, and its diameter is smaller than the diameter of the middle part of the sliding block g, for example, a conical structure or a cylindrical structure with a diameter smaller than the diameter of the middle part of the sliding block g.

[0046] The middle part of the driving rod i is an inwardly recessed arc-shaped engagement part that fits into the guide ring c.

[0047] When the drive motor 321 rotates, it drives the rotating rod d to rotate and the sleeve f fixed on the rotating rod d to rotate. When the sleeve f rotates, it drives the rod i to be subjected to the pressure of the fixed body 31 during rotation, pushing the sliding block g to slide inward or outward, thereby driving the support structure 323 to perform telescopic movement along the axial direction.

[0048] In this embodiment, a transmission structure 322 is set up. The rotational power of the drive motor 321 in the horizontal direction drives the support structure 323 and the image acquisition module 4 to rotate axially. At this time, the squeezing force between the rod i and the fixed body 31 causes the sliding block g to slide inward or outward, which drives the image acquisition module 4 to extend or retract in the horizontal direction. Thus, when the image acquisition module 4 rotates to the next station, the distance between it and the workpiece 5 to be inspected is also slowly shortened, completing the focal length positioning of image acquisition and further improving the efficiency of image acquisition.

[0049] In this embodiment, the support structure 323 includes a main structure in the middle, a first plate extending outward, and a second plate extending inward. The first plate is a 7-shaped plate structure, with its top horizontal position connected to the transmission structure 322 on the inner side and the image acquisition module 4 fixed on the outer side. The second plate is a strip-shaped support extending inward, which is fixed above the platform of the fixing body 31.

[0050] This embodiment includes a main structure in the middle, a first plate extending outward, and a support structure 323 extending inward. The image acquisition module 4 is installed on the first plate, and the image acquisition module 4 on the first plate is supported by the vertical relationship between the main structure and the operating table 1. The engagement between the second plate and the fixing body 31 can further improve the stability of the image acquisition module 4 in the horizontal direction.

[0051] In this embodiment, the fixing body 31 includes a frustum prism 311 mounted on the operating table 1, and a fixing ring 312 fixed on the frustum prism 311; the fixing ring 312 includes a supporting column a and at least two sets of supporting plates b (see...). Figure 1 The guide ring c with a regular hexagonal ring structure is assembled with 3 sets of support plates b. The support column a is fixed at the center of the frustum column 311. The support plates b are evenly installed on the support column a in a radial pattern, and their ends are raised upward and connected to the outer edge of the guide ring c.

[0052] In this embodiment, the support piece b has a “└” structure, with one end connected to the support column a, and the other end extending upward and lifting up to connect with the outer edge of the guide ring c.

[0053] The cross-section of the frustum prism 311 is a regular polygon, including but not limited to regular hexagonal and regular octagonal structures, with its edges gradually tapering upwards from bottom to top. Correspondingly, the guide ring c is a regular polygonal ring structure, including but not limited to regular hexagonal and regular octagonal ring structures. The specific configuration can be determined based on the number of stopping stations.

[0054] In this embodiment, a frustum-shaped column 311 is set as a fixed base, and a corresponding regular polygonal guide ring c is set. Based on communication control, the concave edge is used to create mechanical positioning, which can more accurately position the image acquisition module 4 at the working position, thereby effectively improving the accuracy of image acquisition.

[0055] In this embodiment, the clamping component includes a vertical plate 21, a clamping structure 22, and a rotary motor 23. The vertical plate 21 is vertically installed on the edge of the operating table 1, corresponding one-to-one with the corner of the guide ring c. The clamping structure 22 is fixed on the inner side of the vertical plate 21, and the rotary motor 23 is fixed on the outer side of the vertical plate 21. The clamping structure 22 and the rotary motor 23 are axially connected.

[0056] When the rotary motor 23 rotates, it will drive the clamping structure 22 to rotate in the vertical direction, thereby driving the workpiece 5 to be inspected to rotate.

[0057] In this embodiment, the clamping structure 22 includes a base and multiple limiting blocks. The base is disc-shaped with a reserved mounting position in the center. The multiple limiting blocks are radially installed around the mounting position. Each limiting block includes a fixing block fixed on the base and a slider movably installed on the fixing block.

[0058] Based on the limitations of image capture in the detection environment, this embodiment sets up a corresponding rotary motor 23 for each clamping component, so that the image acquisition module 4 can acquire multi-angle images of the workpiece 5 to be inspected; by utilizing the combined action of the fixed block and the slider movably mounted on the fixed block, it can be compatible with various models of workpiece 5 to be inspected, thus improving the compatibility of the equipment.

[0059] The image acquisition module 4 includes a telescopic structure 41 and an image sensor 42. The telescopic structure 41 is fixed to the first plate, and the image sensor 42 is mounted on the movable end of the telescopic structure 41. The telescopic structure 41 includes, but is not limited to, a lead screw and a cylinder.

[0060] In this embodiment, a telescopic structure 41 is provided to facilitate multi-angle image acquisition of the workpiece 5 to be inspected, which can further transport the image capture device 42 to the target shooting position (e.g., the interior of the hollow workpiece 5 to be inspected) to complete image acquisition.

[0061] In this embodiment, the operating table 1 is a circular operating table 1, with a mounting through hole for mounting the rotary drive module 3 in the middle.

[0062] In this embodiment, six dwelling stations are set up, with Figure 6 Taking workpiece 5 as an example, the working process of the multi-workpiece continuous detection device is as follows:

[0063] The guide ring c is composed of six guide rods of equal length connected together, and the intersection of two adjacent guide rods forms a recess. Correspondingly, the cross section of the frustum prism 311 is a regular hexagonal structure, and the operating table 1 is equipped with 6 sets of clamping components fixed to the outside of the stationary position.

[0064] The workpiece 5 to be inspected has a hollow structure and a constricted neck, with an inlet at the constricted neck. In other embodiments, the workpiece 5 to be inspected may also be a block or plate structure, and its specific shape is not limited.

[0065] First, fix the workpiece 5 to be inspected on the clamping member, push the slider to move in the radial direction, put the workpiece 5 to be inspected in, and the slider retracts to clamp the workpiece 5 to be inspected.

[0066] At this time, the main control module controls the clamping module 2, rotation drive module 3, and image acquisition module 4 to acquire images of the workpiece 5 to be inspected according to the preset process:

[0067] The drive motor 321 starts, causing the rotating rod d to rotate horizontally, which in turn causes the connecting ring e and the sleeve f to rotate. The sliding block g rotates along the inner edge of the guide rod via the driving rod i, while the telescopic spring h applies pressure in the outward direction, forcing the sliding block g to apply continuous outward pressure to the guide rod via the driving rod i. When the sliding block g moves the driving rod i to the intersection position of two adjacent guide rods (the recessed part), the sliding block g moves the image acquisition module 4 outward to its limit position, that is, to the stopping position.

[0068] Drive the telescopic structure 41 and the image capture device 42, control the image capture device 42 to acquire images, and / or control a portion of the telescopic structure 41 and the image capture device 42 to penetrate into the interior of the workpiece 5 to be inspected.

[0069] During image acquisition, the rotary motor 23 can also be controlled to drive the clamping structure 22 and the workpiece 5 to be inspected to rotate in the vertical direction, so as to acquire images from multiple angles.

[0070] After image acquisition at the current workstation is completed, the telescopic structure 41 retracts, allowing the image capture device 42 to disengage from the workpiece 5 to be inspected. Then, the drive motor 321 continues to rotate the sleeve f and sliding block g, subsequently moving the rod i along the guide rod, preparing to acquire images of the next workpiece 5 at the next workstation. The image acquisition module 4 uploads the acquired images to the main control module for data analysis.

[0071] In this embodiment of the invention, a clamping module 2, a rotation drive module 3, and an image acquisition module 4 are configured to communicate with the main control module, establishing an automated image acquisition mechanism. The rotation drive module 3 drives the image acquisition module 4 to rotate in the axial direction, stopping sequentially at different positions to acquire images of the workpiece 5 to be inspected, which is fixed on the clamping component. By keeping the image acquisition position of the workpiece 5 to be inspected stationary, stable continuous image acquisition of multiple workpieces is achieved, reducing shooting errors and thus improving the inspection efficiency of the product.

[0072] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
