[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shown is a structural diagram of an automatic cleaning device for cladding in powder metallurgy, according to an embodiment of the present invention. The automatic cleaning device for cladding in powder metallurgy includes:

[0034] A base 1 is provided with a side support column 2. A support plate 8 is fixedly installed on the side support column 2. Three sets of positioning telescopic cylinders 3 are provided on the support plate 8. The three sets of positioning telescopic cylinders 3 are evenly distributed. A positioning fork 4 is fixedly installed at the end of the positioning telescopic cylinder 3. A roller is rotatably installed at the end of the positioning fork 4. A positioning mark 5 is fixedly installed on the positioning fork 4. A positioning image acquisition device 7 is installed on the top of the support plate 8 through a top bracket 6.

[0035] A sleeve positioning mechanism is fixedly installed on the base 1. The sleeve positioning mechanism is used to automatically identify the position of the sleeve and fix it.

[0036] A sleeve cleaning mechanism is installed on a sleeve positioning mechanism and is used to rinse the sleeve from the inside.

[0037] In this embodiment, the sleeve to be cleaned is placed on the support plate 8 with the opening facing downwards. By setting ball bearings 16 on the support plate 8, the operator can easily slide the sleeve to the center area of ​​the support plate 8. In order to accurately fix the sleeve, the positioning image acquisition device 7 at the top identifies the position of the sleeve, thereby controlling the extension or retraction of each positioning telescopic cylinder 3. Generally speaking, the three sets of positioning telescopic cylinders 3 can directly achieve the purpose of automatic centering. However, since the extension and retraction accuracy of the positioning telescopic cylinders 3 are different, the positioning image acquisition device 7 can be set to achieve fine adjustment of the position of the sleeve, thereby improving the positioning accuracy. After positioning is completed, the sleeve cleaning mechanism is used to rinse from the inside of the sleeve. The rinsing medium is a volatile liquid, such as water or alcohol, to avoid introducing new impurities. During the cleaning process, the cleanliness is identified by image recognition technology until the cleanliness meets the requirements.

[0038] like Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown in a preferred embodiment of the present invention, the sleeve positioning mechanism includes a lifting cylinder 9, which is fixedly mounted on a base 1. A plurality of guide rods 11 are fixedly arranged between the base 1 and a support plate 8. A set of lifting plates 12 and a set of mounting plates are slidably arranged on the guide rods 11. The lifting plates 12 are fixedly mounted on the telescopic end 10 of the lifting cylinder 9. The sleeve cleaning mechanism includes a liquid inlet pipe 18, which is fixedly mounted on the lifting plate 12. A nozzle is rotatably connected to the top of the liquid inlet pipe 18. The nozzle includes a top flushing port 29 and an eccentric flushing port 30. A spring 13 is sleeved around the portion of the guide rod 11 located between the mounting plate and the lifting plate 12. A sealing seat 17 is fixedly mounted on the mounting plate. A hollow frustum 21 is mounted on the sealing seat 17. Multiple sets of support rods 25 are fixedly mounted at the ends of the hollow frustum 21. Limit rods are fixedly mounted on the support rods 25. A set of hollow threaded rods 19 is rotatably connected inside the hollow frustum 21 via a sealed bearing 22. The periphery of the hollow threaded rods 19 is connected via threads. A threaded sleeve 24 is attached, and a guide groove is provided on the outer diameter of the threaded sleeve 24. The guide groove is slidably connected to the support rod 25. The threaded sleeve 24 is rotatably connected to a clamping rod 26 via a connecting rod. The clamping rod 26 is provided with a sliding groove 27, and the limiting rod is slidably disposed in the sliding groove 27. A return port and a return liquid chamber 33 are opened on the hollow threaded rod 19. A sealing ring is connected to the periphery of the hollow threaded rod 19 via a waterproof bearing assembly 31. A return liquid pipe 32 is connected to the sealing ring. The inlet pipe 18 enters from inside the hollow threaded rod 19. The inlet pipe 18 and the hollow threaded rod 19 are connected by a bearing. A set of sampling boxes 14 are fixedly installed on the mounting plate. The sampling boxes 14 are connected to the return pipe 32 and the inlet pipe 18. Two sets of receiving cavities are provided in the sampling boxes 14. A set of comparison image acquisition devices 15 are fixedly installed on the mounting plate. The comparison image acquisition devices 15 are used to acquire images of the two sets of receiving cavities to determine whether the cleaning of the casing is completed. A rotary motor is fixedly installed at the bottom of the mounting plate. A worm gear is installed on the rotary motor. The worm gear meshes with the worm wheel 28.

[0039] In this embodiment, during cleaning, after the positioning image acquisition device 7, in conjunction with the positioning telescopic cylinder 3, completes the positioning of the sleeve, the lifting cylinder 9 is activated. The lifting cylinder drives the lifting plate 12 to rise, and the lifting plate 12, through the spring 13, drives the mounting plate to rise until the hollow frustum 21 on the sealing seat 7 is inserted into the lower opening of the sleeve. At this time, the hollow frustum 21 abuts against the opening, and the rotary motor on the mounting plate is activated. The rotary motor drives the worm gear to rotate, and the worm gear drives the worm wheel 28 to rotate. At this time, the worm wheel 28 will drive the hollow threaded rod 19 to rotate. Since the outer edge of the threaded sleeve 24 is slidably connected to the support rod 25, the threaded sleeve 24 will move upward. The threaded sleeve 24 will drive the clamping rod 26 to move upward. When the position where the clamping rod 26 and the connecting rod on the threaded sleeve 24 are hinged is higher than the limit rod, the clamping rod 26 will flip, so that the end of the clamping rod 26 abuts against the inner wall of the sleeve, thereby cooperating with the hollow frustum 21 to lift the sleeve. The clamping mechanism is engaged, and the lifting cylinder 9 is further lifted, compressing the spring 13. The inlet pipe 18 drives the nozzle to enter the casing from inside the hollow threaded rod 19. A sealing ring is provided between the inlet pipe 18 and the hollow threaded rod 19. After the nozzle enters, it sprays cleaning fluid into the casing via an external water pump. The cleaning fluid can be water or alcohol. The cleaning fluid is sprayed out simultaneously through the top flushing port 29 and the eccentric flushing port 30. The outflow direction of the eccentric flushing port 30 is tangent to the outer edge of the inlet pipe 18. During the process of spraying cleaning fluid through the eccentric flushing port 30, the nozzle will rotate relative to the inlet pipe 18, thereby achieving omnidirectional cleaning. During the cleaning process, the lifting cylinder 9 descends according to the preset moving step length, thereby completing the multi-stage cleaning of the inner wall of the casing. During each cleaning stage, the image acquisition device 15 is used to acquire images to determine whether the current stage is clean. If it is clean, the next stage is entered.

[0040] like Figure 1 and Figure 5 As shown, in a preferred embodiment of the present invention, an airbag 20 is provided on the periphery of the hollow truncated cone 21, and an air supply pipe 23 is also embedded in the hollow truncated cone 21, which is connected to the airbag 20.

[0041] In this embodiment, by setting an airbag 20, after the hollow frustum 21 enters the opening on the sleeve, the airbag 20 is inflated to fill the gap between the hollow frustum 21 and the inner wall of the sleeve.

[0042] like Figure 1 and Figure 5 As shown, in a preferred embodiment of the present invention, the support plate 8 is provided with a clearance groove, and ball bearings 16 are installed on both sides of the clearance groove on the support plate 8.

[0043] In this embodiment, when placing the sleeve, the inlet of the sleeve is inserted into the clearance groove, thereby pushing the sleeve and causing it to roll along the ball until the sleeve enters the central area on the support plate 8.

[0044] like Figure 1 As shown, in a preferred embodiment of the present invention, a supplementary light is provided on the side of the sampling box 14 away from the contrast image acquisition device 15.

[0045] In this embodiment, a supplementary light is provided to improve the quality of image acquisition.

[0046] like Figure 1 As shown, in a preferred embodiment of the present invention, the automatic positioning of the package is completed during the cleaning process, specifically including:

[0047] The positioning image is obtained by acquiring the image using the positioning image acquisition device 7.

[0048] In this step, the positioning image acquisition device 7 performs real-time detection on the screen. When a screen change is initially detected, it starts acquiring images at preset time intervals until the acquired images no longer show screen changes. At this point, a new set of images is acquired to obtain the positioning image.

[0049] The localization image is preprocessed, and edge detection is performed on the preprocessed image to obtain an edge-detected image.

[0050] In this embodiment, the positioning image is processed in grayscale to reduce the color information in the image. Then, the edge detection algorithm is used to complete the edge detection processing of the image. By recognizing the shape of the edge, the location of the bag can be determined, and then the center position of the bag can be determined. The center position of the bag is marked in the edge detection image.

[0051] The positioning identifier 5 contained in the positioning image is identified, the control parameters of the positioning telescopic cylinder 3 are obtained, and a telescopic control command is generated. The positioning telescopic cylinder 3 positions the package according to the telescopic control command.

[0052] In this embodiment, the positioning mark 5 contained in the positioning image is identified. The positioning mark 5 can be a sticker of a specific shape and color, such as a circular sticker of a specific color. By identifying the color and shape information in the positioning image, the position of the positioning mark 5 can be determined, which can indirectly determine the position of the positioning fork 4. The positioning fork 4 is equipped with two sets of rollers, so the sleeve can roll relative to the positioning fork 4. By determining the position of the positioning fork 4, it can be determined whether each positioning fork 4 needs to be extended or retracted, thereby completing an adjustment. After the adjustment is completed, positioning is performed again to determine whether the sleeve has reached the preset position. Based on the deviation between the actual position of the sleeve and the preset position, the extension and retraction of each positioning fork 4 are determined to avoid the influence of the accuracy of the positioning telescopic cylinder 3.

[0053] like Figure 1 As shown, in a preferred embodiment of the present invention, the step of acquiring images of the two sets of receiving cavities and determining whether the cleaning of the sheath is complete specifically includes:

[0054] Images are acquired at preset time intervals to obtain comparison images to be processed.

[0055] In this step, images are acquired at preset time intervals. The sampling box 14 contains two transparent cavities. The cavities are connected to the inlet pipe 18 and the return pipe 32 via an electronically controlled valve. The electronically controlled valve can control the source of the liquid flowing into the two cavities. The cavities are the first and second cavities. Both the first and second cavities can accommodate the inflow and outflow of liquid. Comparison images to be processed are acquired at preset time intervals. For example, after the cleaning begins, a set of comparison images to be processed is acquired every 10 seconds.

[0056] The images to be compared are split into a first image and a second image. Color value analysis is performed on the first image and the second image to calculate pixel similarity and determine whether the initial test is passed. If the pixel similarity is greater than a preset value, the initial test is considered to have passed.

[0057] In this step, the images to be processed and compared are split, edge recognition is performed, and the image regions corresponding to the two cavities are determined. The first image and the second image are extracted. At this time, the first cavity contains inflowing liquid, corresponding to the first image, and the second cavity contains outflowing liquid, corresponding to the second image. The pixels in the first image and the second image are numbered according to a preset order. Pixels with the same number are compared, such as numbering from left to right and from top to bottom. The color value difference of the compared pixels is calculated, such as the difference of the three-channel color values ​​of the two pixels. If the color value difference of any channel is within a preset range, the two are judged to be similar pixels; otherwise, they are abnormal pixels. Grayscale processing is performed on the two sets of images, and the mean grayscale value is calculated. Pixel similarity is the ratio of the number of similar pixels to the total number of pixels. If the pixel similarity is greater than a preset value and the difference of the mean grayscale values ​​of the two sets of images is within a preset range, the initial test is judged to be passed; otherwise, the initial test is judged to be failed. If the initial test fails, it is considered that the cleaning is not yet complete, and the cleaning process continues.

[0058] If the initial test is passed, the sample sources of the two sets of cavities are switched for a second test. If the pixel similarity during the second test is greater than the preset value, the cleaning is considered complete.

[0059] In this step, when the initial inspection is passed, the sample source of the two sets of receiving cavities is switched. Initially, the first receiving cavity contains inflow liquid and the second receiving cavity contains outflow liquid. After switching, the second receiving cavity contains inflow liquid and the first receiving cavity contains outflow liquid. By exchanging these contents, the influence of light and background on the image is eliminated. The initial inspection process is repeated to determine whether the re-inspection is passed. If the re-inspection is passed, it means that the cleaning is complete and the cleaning process is stopped. After the cleaning is complete, the input source of the liquid inlet pipe 18 is switched to clean gas to dry the inner cavity of the casing. Alternatively, a higher temperature gas can be introduced to increase the drying speed. After the cleaning is completed, the casing is pushed to the edge of the support plate 8 by the cooperation of the three sets of positioning telescopic cylinders 3.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
