Description

Technical Field

[0001] This invention relates to the field of fluid control device technology, and in particular to a control method and device for secondary shaping of valve seats. Background Technology

[0002] The valve seat is the core functional component of a valve. Its function is not only to support the valve core and form a sealing pair, but also directly determines the reliability of the valve under complex working conditions. The sealing performance, structural stability and wear resistance of the valve seat are directly related to whether the system medium leaks, the service life of the equipment, and may even affect production safety.

[0003] In the valve seat manufacturing process, double-sided integrity inspection and precise directional conveying are two key pre-processing steps that directly affect the quality of subsequent processing and the final product qualification rate. Currently, these processes are generally carried out manually. Manual inspection and conveying are conducted by visually inspecting the upper and lower end faces, sealing surfaces, and edges of the valve seat to check for scratches, cracks, missing materials, air holes, dents, and other appearance defects. According to the tooling requirements of the subsequent processing equipment, the qualified valve seats must be placed at a specified angle to ensure that the processing reference surface of the valve seat is precisely aligned with the spindle of the equipment.

[0004] However, the current operation mode, which relies entirely on manual labor, has many unavoidable shortcomings. For example, when valve seats with bumps or burrs are detected, they are all recycled and discarded, resulting in low product qualification rate and production efficiency. Summary of the Invention

[0005] To improve product qualification rate and production efficiency, this invention provides a control method and equipment for secondary shaping of valve seats.

[0006] In a first aspect, the present invention provides a control method for a secondary shaping device for valve seats, employing the following technical solution:

[0007] A control method for a valve seat secondary shaping device, applied to a valve seat secondary shaping device, further includes:

[0008] Step 100: Acquire a frontal image of the valve seat at the first inspection station;

[0009] Step 101: When a preset shadow anomaly feature exists in the front image of the valve seat, determine the location of the shadow anomaly based on the front image of the valve seat and the shadow anomaly feature;

[0010] Step 102: Control the preset illumination lamp to flash the shadow abnormality location and acquire the exposure image of the abnormal location;

[0011] Step 103: Analyze the shadow anomaly location from the exposed image at the anomaly location to determine the anomaly type, which includes concave features and convex features;

[0012] Step 104: When there is a dent feature in the exposed image of the abnormal position, it is defined as a defective product. The push plate preset on the first detection station is controlled to push the valve seat and drop it into the preset waste bin.

[0013] Step 105: When there are protruding features in the abnormal position exposure image, identify all the protruding features in the abnormal position exposure image, determine the protruding contour range of each protruding feature, and filter out the largest contour from all the protruding contour ranges of the protruding features.

[0014] Step 1050: When the maximum profile is not less than the preset reference profile area, it is defined that there is a blocky protrusion abnormality on the top of the valve seat, and it is processed by the preset laser polishing method.

[0015] Step 1051: When the maximum profile area is smaller than the reference profile area, it is defined that there is a point-like protrusion abnormality on the top of the valve seat, and it is processed by the preset flip-grinding method.

[0016] Optional, flipping and smoothing methods include:

[0017] Step 10510: Identify all protruding features from the image exposed at the abnormal location and determine the burr protrusion height of each protruding feature;

[0018] Step 10511: Select the maximum burr height from the burr protrusion heights;

[0019] Step 10512: Determine the starting height for flipping based on the maximum burr height, and determine the flipping and polishing force based on the maximum contour.

[0020] Step 10513: Control the clamping component to clamp the valve seat and rotate it 180°, and control the height between the grinding disc and the valve seat preset on the first detection station based on the starting height of the rotation;

[0021] Step 10514: Control the clamping component to move relative to the valve seat by the preset grinding path, and control the grinding disc to approach the valve seat by the flipping grinding force and the preset rising speed until the valve seat and the grinding disc abut against each other to complete the grinding. The grinding path is the path of the clamping component reciprocating horizontally into and out of the first detection station.

[0059] In summary, the present invention has at least one of the following beneficial technical effects:

[0060] Based on the different shadow anomalies that may appear in the front image of the valve seat, different processing methods are selectively applied. For example, if a dent is found, the product is discarded. If a bulge is found, different repair methods are selected according to the size and contour range of the bulge, thereby reducing the number of defective products that are directly discarded and improving the product qualification rate.

[0061] The dual-axis drive unit and clamping unit work together to move the valve seat sequentially from the first inspection station to the second inspection station and then to the sorting station. Inspection is performed on both sides at the first and second inspection stations. A flipping and shaping unit and a rotating shaping unit reshape the valve seat twice during its movement, ensuring it is placed at the correct angle at the sorting station for subsequent processing. The flipping and shaping unit's rotation of the valve seat allows for inspection of both sides, reducing blind spots and improving product quality stability. Furthermore, the movement and transport by the dual-axis drive unit and clamping unit improves conveying efficiency, thereby increasing production efficiency.

[0062] Based on the detection results from the identification component, the lifting and diverting component transfers defective valve seats to the collection component for recycling, and lifts qualified valve seats upwards to be transferred to the subsequent processing position with the pre-set clamping device. During the upward lifting process, the clamping and limiting component keeps the valve seat clamped to improve the stability of valve seat transportation and prevent the valve seat from moving or rotating, which would cause inaccurate subsequent processing, thereby improving the stability of product quality.

[0073] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0074] This invention discloses a secondary shaping device for valve seats, referring to... Figure 1 and Figure 2A secondary shaping device for valve seats includes a mounting frame 1, a detection assembly 2, a conveying assembly 3, and a sorting and discharging assembly 4. The mounting frame 1 is used to mount the detection assembly 2, the conveying assembly 3, and the sorting and discharging assembly 4, and a back plate 11 is provided at the rear end of the mounting frame 1. The detection assembly 2 has a first detection station 24 and a second detection station 25. The detection assembly 2 is used to detect the integrity and placement angle of the valve seats. The sorting and discharging assembly 4 has a sorting station 44. The sorting station 44 is located to one side of the second detection station 25, and the sorting and discharging assembly 4 is used to sort and discharge the valve seats that have completed the detection. The distance between the first detection station 24 and the second detection station 25 is the same as the distance between the second detection station 25 and the sorting station 44, and they are located on the same horizontal plane.

[0075] The detection component 2 includes two identification components 21, a feeding component 22, and a rotating shaping component 23. The two identification components 21 are fixedly mounted on the back plate 11 and are used to detect valve seats on the first detection station 24 and the second detection station 25, respectively. The identification components 21 can be industrial cameras, which are used in conjunction with a vision inspection system to complete the detection. The vision inspection method is existing technology and will not be described in detail here.

[0076] The feeding component 22 includes a first cylinder 221, a feeding plate 222, and two first limiting rods 223. The first cylinder 221 is fixedly mounted on the mounting frame 1, and the push rod of the first cylinder 221 passes through the mounting frame 1 from bottom to top. The feeding plate 222 is fixedly mounted on the output end of the first cylinder 221, and one side of the feeding plate 222 abuts against the back plate 11. The two first limiting rods 223 are fixedly mounted on the lower end of the feeding plate 222, and pass through the mounting frame 1 from top to bottom and are slidably connected to the mounting frame 1. When the first cylinder 221 drives the feeding plate 222 to stop lifting, the feeding plate 222 is at the first inspection station 24.

[0077] The rotating shaping component 23 includes a placement plate 231, a rotating plate 232, and a first motor 233. The placement plate 231 is horizontally positioned and fixedly mounted on the back plate 11. The rotating plate 232 is rotatably mounted on the placement plate 231. The first motor 233 is fixedly mounted on the mounting bracket 1, and its output end is fixedly connected to the rotating plate 232 to drive the rotating plate 232 to rotate. The rotating plate 232 is located at the second inspection station 25.

[0078] With the above structure, the valve seat is placed on the loading plate 222. The first cylinder 221 lifts and drives the loading plate 222 to move to the first inspection station 24. The identification component 21 inspects the valve seat on the loading plate 222. After inspection, the conveying assembly 3 flips the valve seat on the loading plate 222 and conveys it to the rotating plate 232. The identification component 21 inspects the valve seat on the rotating plate 232. After inspection, the first motor 233 runs and drives the rotating plate 232 to rotate, thereby adjusting the angle of the valve seat above it. By having two identification components 21 inspect both sides of the valve seat, the blind spot is reduced, which can effectively screen out defective valve seats and improve product quality.

[0079] Reference Figure 3 and Figure 4 The conveying assembly 3 includes a dual-axis drive component 31, a flipping and shaping component 32, and a clamping component 33. The dual-axis drive component 31 includes a first moving structure 311 and a second moving structure 312. The second moving structure 312 is fixedly mounted on the mounting frame 1, and the first moving structure 311 is fixedly mounted on the moving end of the second moving structure 312. The moving end of the first moving structure 311 is connected to the flipping and shaping component 32.

[0080] Both the first moving structure 311 and the second moving structure 312 can be linear modules or other mechanical structures that can achieve the same effect, which are well known to those skilled in the art and will not be described in detail here.

[0081] The flipping and shaping component 32 includes a mounting plate 321, a second cylinder 322, a rack 323, and a first gear 324. The mounting plate 321 is a rectangular strip, fixedly mounted on the moving end of the first moving structure 311. An inverted L-shaped support frame is provided on the mounting plate 321, and the second cylinder 322 is fixedly mounted on the support frame. The rack 323 is fixedly connected to the output end of the second cylinder 322, and the rack 323 is slidably connected to the support frame, allowing the second cylinder 322 to drive the rack 323 to rise and fall. The first gear 324 is rotatably mounted on the mounting plate 321 and meshes with the rack 323.

[0082] The clamping component 33 includes two identical first clamping components 33a and a second clamping component 33b, which are respectively installed at both ends of the mounting plate 321. The clamping component 33 includes a clamping cylinder 331, two clamping frames 332, and two auxiliary pads 333. The two clamping frames 332 are symmetrically arranged and fixedly installed on the output end of the clamping cylinder 331. A receiving groove 3321 is formed on one side of the two clamping frames 332 that is close to each other. The receiving groove 3321 is semi-circular. The two auxiliary pads 333 are respectively fixedly installed in the two receiving grooves 3321. The auxiliary pads 333 can be made of soft foam.

[0083] The first clamping component 33a is rotatably mounted on the mounting plate 321, and the clamping cylinder 331 of the first clamping component 33a is fixedly connected to the first gear 324. When the second cylinder 322 drives the rack 323 to rise and fall, the first clamping component 33a can rotate through the intermediate transmission of the first gear 324.

[0084] The second clamping component 33b is fixedly connected to the mounting plate 321.

[0085] In this embodiment, the second moving structure 312 drives the flipping and shaping component 32 to move along the X-axis, allowing the clamping component 33 to move on the first inspection station 24, the second inspection station 25, and the sorting station 44. The first moving structure 311 drives the flipping and shaping component 32 to move along the Y-axis, allowing the clamping component 33 to move closer to or further away from the valve seat to avoid the placed valve seat. The X-axis direction is perpendicular to the Y-axis direction.

[0086] With the above structure, after the identification component 21 detects the valve seat on the feeding plate 222, the first moving structure 311 and the second moving structure 312 cooperate to drive the two clamping components 33 to move to the feeding plate 222 and the rotating plate 232 respectively. The clamping cylinder 331 is activated to drive the two clamping frames 332 to move closer to each other and clamp. The auxiliary pad 333 contacts the valve seat and gradually deforms to complete the clamping of the valve seat. The operation of the first cylinder 221 drives the feeding plate 222 to descend for secondary feeding, while avoiding the clamping cylinder 331. The second cylinder 322 is activated to drive the rack 323 to move along the support frame. The rack 323 drives the gear and the clamping cylinder 331 to rotate in sequence, thereby causing the valve seat to rotate 180 degrees.

[0087] The first moving structure 311 and the second moving structure 312 cooperate to move the first clamping component 33a corresponding to the first inspection station 24 to the second inspection station 25. At this time, the first clamping component 33a corresponding to the second inspection station 25 moves to the sorting station 44, completing the conveying of the valve seat. By setting the flipping and shaping component 32, the valve seat on the first inspection station 24 can be flipped 180 degrees after inspection. At the same time, the dual-axis drive component 31, together with the two clamping components 33, can complete the segmented transfer of the valve seat from the first inspection station 24 to the second inspection station 25 and then to the sorting station 44, improving the inspection and shaping efficiency.

[0088] Reference Figure 5 and Figure 6 The sorting and discharging component 4 includes a lifting and diverting component 41, a clamping and limiting component 42, and a collecting component 43.

The third cylinder 411 is fixedly mounted on the mounting frame 1, and the push rod of the third cylinder 411 passes through the mounting frame 1 from bottom to top. The lifting seat 412 includes a lifting plate 4124 and a lifting platform 4125 mounted on the lifting plate 4124. A cavity is formed between the lifting plate 4124 and the lifting platform 4125, and the top of the lifting platform 4125 has an opening extending into the cavity. A support slide rod 4111 is horizontally arranged at the output end of the third cylinder 411, and a slot frame 4121 is arranged at the bottom of the lifting plate 4124. The support slide rod 4111 slides within the slot frame 4121. The third cylinder 411 can drive the lifting seat 412 to rise and fall.

A limit post 4123 is fixedly installed at the rear end of the lifting plate 4124. A rotating slot frame 413 is fixedly installed on the side of the placement plate 231 facing the lifting seat 412. The rotating slot frame 413 has a slot that cooperates with the rotation of the rotating shaft 4122.

[0091] The auxiliary plate 414 is fixedly installed on the mounting bracket 1 and located behind the lifting seat 412. The auxiliary plate 414 has a first through groove 4141 and a second through groove 4142 extending through the front and rear. A trajectory groove 4143 is formed in the second through groove 4142. The limiting post 4123 is located in the first through groove 4141 and slides along the first through groove 4141. Both the first through groove 4141 and the second through groove 4142 include a vertically opened vertical groove and an arc-shaped groove with the rotating shaft 4122 as the rotation center. The trajectory groove 4143 is composed of a compression section 41431, an inclined section 41432, a clamping section 41433 and an unlocking section 41434 from bottom to top. The compression section 41431 is located in the arc-shaped groove of the second through groove 4142.

[0092] The third cylinder 411 drives the lifting seat 412 to rise and fall, having both tilted and jacking states.

[0093] When the valve seat is detected as defective, the third cylinder 411 drives the lifting seat 412 to move downwards. The rotating shaft 4122, located in the rotating slot frame 413, cannot move downwards, so the rotating shaft 4122 can only rotate within the rotating slot frame 413. The limiting post 4123 moves along the arc section of the first through groove 4141, and the supporting slide rod 4111 moves along the slide frame 4121, causing the lifting seat 412 to rotate and tilt along the rotating shaft 4122. At this time, the lifting seat 412 is in an inclined state, and the valve seat located on the sorting station 44 tilts and falls into the collecting component 43 for collection.

[0094] When the valve seat is detected as qualified, the third cylinder 411 drives the lifting seat 412 to move upward, the rotating shaft 4122 disengages from the rotating slot frame 413, and the limiting post 4123 moves along the vertical section of the first through slot 4141 to prevent the lifting seat 412 from tilting. The valve seat rises with the lifting seat 412. At this time, the lifting seat 412 is in the lifting state, and the external clamping device unloads the rising valve seat.

[0095] By using the rotating shaft 4122 and the rotating slot frame 413, the downward-moving lifting frame tilts, causing the valve seat to tilt into the collecting component 43. Meanwhile, the upward-moving lifting frame moves horizontally upward under the limiting support of the limiting column 4123, thus cooperating with the external clamping device for subsequent processing, achieving efficient diversion of good and bad valve seats.

[0096] Reference Figure 7 , Figure 8 and Figure 9 The clamping and limiting component 42 includes an adjustment structure 421, four limiting structures 422, a track frame 423, and a clamping structure 424.

[0097] The adjustment structure 421 includes a second motor 4211, a second gear 4212, a gear disc 4213, and a placement seat 4214. The placement seat 4214 is fixedly mounted on the lifting seat 412, and the gear disc 4213 is rotatably mounted on the outside of the placement seat 4214. Both the placement seat 4214 and the gear disc 4213 are located in a cavity. The second gear 4212 is rotatably mounted on the lifting seat 412. The output end of the second motor 4211 is fixedly connected to the second gear 4212, and the second gear 4212 meshes with the gear disc 4213. The lifting platform 4125 has a clearance hole for the second gear 4212 to pass through.

[0098] When the lifting seat 412 is in a horizontal state and the rotating shaft 4122 is located in the rotating slot frame 413, the top surface of the placement seat 4214 and the top surface of the rotating plate 232 are on the same horizontal plane, that is, the position of the placement seat 4214 at this time is the sorting station 44.

[0099] There are four limiting structures 422, circumferentially distributed on the gear disk 4213. Each limiting structure 422 includes a second limiting rod 4221, a first spring 4222, an abutment block 4223, and a pulley 4224. The second limiting rod 4221 is fixedly mounted on the gear disk 4213, and the abutment block 4223 is sleeved on and slidably connected to the second limiting rod 4221. The first spring 4222 is sleeved on the second limiting rod 4221, and its two ends are fixedly connected to the gear disk 4213 and the abutment block 4223, respectively. The first spring 4222 drives the abutment block 4223 to always have an upward tendency. The pulley 4224 is rotatably mounted on the abutment block 4223. The abutment block 4223 has a groove on the side facing the placement seat 4214 to abut against the valve seat. Each abutment block 4223 has a different groove to accommodate different placement angles of the corresponding valve seat. The side of the abutment block 4223 away from the placement seat 4214 has a slope.

[0100] The track frame 423 is fixedly installed on the top of the lifting platform 4125. The track frame 423 is in the shape of a ring and has a horizontal rolling surface and an inclined rolling surface. The horizontal rolling surface and the inclined rolling surface each occupy half of the arc of the track frame 423.

[0101] The pulley 4224 abuts against the surface of the track frame 423 and can roll along the track frame 423. When the pulley 4224 rolls along the horizontal rolling surface, it drives the abutment block 4223 to compress the first spring 4222. When the pulley 4224 rolls along the inclined rolling surface, the first spring 4222 drives the corresponding abutment block 4223 to extend out from the opening of the lifting platform 4125 and rise to the sorting station 44. At this time, the abutment block 4223 can abut against the valve seat side.

[0102] Through the above structure, the second motor 4211 drives the second gear 4212 to rotate, the second gear 4212 drives the gear disc 4213 to rotate, and the gear disc 4213 drives the second limit rod 4221 and the abutment block 4223 to move, thereby driving the pulley 4224 to roll along the track frame 423. When the pulley 4224 rolls from the horizontal rolling surface to the inclined rolling surface, the abutment block 4223 gradually lowers, thereby compressing the first spring 4222. When one of the pulleys 4224 moves to the center of the inclined rolling surface, the pulley 4224 is farthest from the lifting plate 4124, and the abutment block 4223 corresponding to the pulley 4224 moves upward to the sorting station 44, while the other three pulleys 4224 are all located on the horizontal rolling surface. The corresponding abutment blocks 4223, driven by the pulleys 4224, continuously press the first spring 4222, thereby being located inside the lifting seat 412.

[0103] By having multiple abutment blocks 4223 rotate with the gear disc 4213 and move up and down along the track frame 423 driven by the pulley 4224, the switching between multiple abutment blocks 4223 is realized. This allows for adjustment according to the fixing requirements of valve seats at different angles, thus improving adaptability.

[0104] The clamping structure 424 includes a clamping block 4241, a limiting slide rod 4242, a second spring 4243, a limiting block 4244, a connecting rod 4245, and two sliding wheels 4246. The limiting block 4244 is fixedly installed on the lifting platform 4125 of the lifting seat 412. The limiting slide rod 4242 passes through the limiting block 4244 and is slidably connected to the limiting block 4244. The limiting block 4244 has a polygonal groove for cooperating with the limiting slide rod 4242. The clamping block 4241 is fixedly connected to one end of the limiting slide rod 4242. The second spring 4243 is sleeved on the outside of the limiting slide rod 4242, and both ends of the second spring 4243 abut against the clamping block 4241 and the limiting block 4244, respectively. The connecting rod 4245 is detachably connected to the end of the limiting slide bar 4242 away from the clamping block 4241, and the connecting rod 4245 passes through the second through groove 4142 and can slide up and down in the second through groove 4142. The sliding wheel 4246 is rotatably connected to the connecting rod 4245 and is located in the track groove 4143 and is in rolling connection with the auxiliary plate 414.

[0105] The collection component 43 includes a collection box 431 and a collection plate 432. The collection box 431 is fixedly mounted on the mounting frame 1 and located on the side of the lifting seat 412 away from the rotating slot frame 413. The collection plate 432 is obliquely mounted and fixedly mounted on the side of the collection box 431 close to the mounting frame 1.

[0106] With the above structure, when the second clamping component 33b clamps the valve seat and moves it to the sorting station 44, the valve seat first contacts the inclined surface of the abutment block 4223 and slides along the inclined surface to compress the first spring 4222. When the valve seat moves to the placement seat 4214, the valve seat no longer presses the abutment block 4223, and the first spring 4222 pushes the abutment block 4223 to abut against the valve seat.

[0107] When the valve seat is found to be qualified, the lifting seat 412 drives the valve seat to move upward. At this time, the connecting rod 4245 slides along the vertical groove of the second through groove 4142, and the sliding wheel 4246 rolls synchronously along the inclined section 41432 of the track groove 4143 to the clamping section 41433. When the sliding wheel 4246 rolls to the clamping section 41433, the second spring 4243 pushes the clamping block 4241 to move towards the valve seat and abut against the valve seat, thereby driving the valve seat to press against the abutment block 4223 to complete the fixation.

[0108] As the lifting seat 412 continues to rise, the sliding wheel 4246 rolls to the unlocking section 41434, causing the clamping block 4241 to move away from the valve seat along with the limiting slide bar 4242 and the connecting rod 4245, thereby completing the unlocking.

[0109] When the valve seat is detected as defective, the lifting seat 412 rotates along the rotating shaft 4122. At this time, the connecting rod 4245 slides along the arc groove of the second through groove 4142, and the sliding wheel 4246 rolls along the compression section 41431 so that the clamping block 4241 always keeps pressing the second spring 4243. The valve seat slides down onto the collecting plate 432 under the action of tilting and enters the collecting box 431 to complete the collection.

[0110] By moving along with the sliding wheel 4246 and pressing against the valve seat under the force of the second spring 4243 during the lifting process of the lifting seat 412, the valve seat is fixed during the lifting process, preventing the valve seat from shaking and causing the angle to change, thus affecting subsequent processing. At the same time, the unlocking section 41434 of the track groove 4143 ensures that the valve seat is not fixed when it moves to the top, which is convenient for operation with the clamping equipment.

[0111] Based on the same inventive concept, embodiments of the present invention provide a control method for a secondary shaping device for valve seats. By performing image recognition on the valve seat at the first detection station 24, it is determined whether there are abnormal protrusions and depressions on the surface of the valve seat and targeted processing is performed to avoid the abnormal features affecting the adjustment of the valve seat position angle when the valve seat moves to the second detection station 25.

[0112] A control method for a valve seat secondary shaping device includes the following steps:

[0113] Step 100: Acquire a frontal image of the valve seat at the first inspection station 24.

[0114] The front image of the valve seat refers to the image obtained by taking a top-down view of the valve seat located on the first inspection station 24. The image is captured by the identification component 21 fixed above the first inspection station 24, which is a camera.

[0115] Step 101: When a preset shadow anomaly feature exists in the front image of the valve seat, determine the shadow anomaly location based on the front image of the valve seat and the shadow anomaly feature.

[0116] Shadow anomaly features refer to the parts in the front image of the valve seat that have significant gray-level differences, such as gray-level values ​​that are more than 15 higher or lower than the reference plane, and the pixel brightness change rate of the edge part is not less than 50. Based on the above characteristics, image recognition analysis can be performed on the front image of the valve seat to determine the shadow anomaly features.

[0117] The location of the shadow anomaly refers to the actual location of the shadow anomaly on the valve seat. The location of the shadow anomaly in the image can be determined from the front image of the valve seat. Then, by combining the reference point determined by the location in the image and the image scale when the image was taken, the location of the shadow anomaly can be determined.

[0118] Step 102: Control the preset illumination lamp to flash the shadow abnormality location and acquire the exposure image of the abnormal location.

[0119] An abnormal location exposure image refers to a high-exposure image of the valve seat located at the first detection station 24 taken from above. It is captured synchronously by the control and recognition component 21 at the moment the illumination lamp flashes. In the high-exposure image, the shadow area is significantly brightened, and the originally hidden dark details will be "revealed", so that the shadow is no longer a "featureless dark block" but an analyzable structured area.

[0120] Step 103: Analyze the shadow anomaly location from the exposed image at the anomaly location to determine the anomaly type, which includes concave features and convex features.

[0121] A depression feature refers to a region that meets a pre-defined range of image parameters, such as a gray value that is 20 to 40 lower than the reference plane and has uniform gray values ​​inside.

[0122] A raised feature refers to an area that meets the preset range of image parameters for the raised area, such as a gray value that is 15 to 30 higher than the reference plane or an internal local gray value that is lower than the reference plane and has a prominent outline.

[0123] Step 104: When there is a dent feature in the image of the abnormal position, it is defined as a defective product. The push plate preset on the first detection station 24 is controlled to push the valve seat and drop it into the preset waste bin.

[0124] When a dent is visible in the exposed image of an abnormal location, it indicates that the valve seat has a dent that cannot be repaired in this process, and is therefore determined to be a defective product and discarded directly. In this embodiment, a push plate and a waste bin are provided on one side of the first inspection station 24. The push plate sends the defective valve seat to the waste bin for recycling.

[0125] Step 105: When there are protruding features in the abnormal location exposure image, identify all the protruding features in the abnormal location exposure image, determine the protruding contour range of each protruding feature, and filter out the largest contour from all the protruding contour ranges of the protruding features.

[0126] The protrusion contour range refers to the range of the outermost contour of the protrusion on the valve seat surface, which can be obtained by identifying the position with a high grayscale difference in the abnormal position exposure image.

[0127] The maximum contour refers to the contour range with the largest area among all the raised features, which can be obtained by comparing the areas of all the raised contour ranges.

[0128] When a raised feature is present in the image of an abnormal location, it indicates that there is a protrusion on the front of the valve seat. In subsequent steps, when the valve seat is flipped and placed on the second inspection station 25, the protrusion may cause the valve seat to tilt, thus affecting the stability of the placement and hindering subsequent processing. Therefore, the protrusion needs to be removed.

[0129] Step 1050: When the maximum profile is not less than the preset reference profile area, it is defined that there is a blocky protrusion abnormality on the top of the valve seat, and it is processed by the preset laser polishing method.

[0130] The reference contour area is a pre-set area value by the operator and serves as a critical value for distinguishing protrusion types. The specific setting value is selected by the operator based on the actual situation and will not be elaborated here. When the maximum contour area is not less than the preset reference contour area, it indicates that there are large blocks on the valve seat surface.

[0131] When there are protrusions with a large outline area, the surface treatment of the valve seat needs to be determined based on the protrusion. For valve seats with protrusions with a large outline area, the system uses laser polishing to process all protrusions on the entire top surface of the valve seat. The laser polishing method will not be described in detail here, but will be introduced in detail in subsequent embodiments.

[0132] Step 1051: When the maximum profile area is smaller than the reference profile area, it is defined that there is a point-like protrusion abnormality on the top of the valve seat, and it is processed by the preset flip-grinding method.

[0133] When the maximum profile area is smaller than the reference profile area, it indicates that the protrusions on the valve seat surface are all small and appear as dots, which are identified as burrs. Since the protrusions on the valve seat surface are small, the system uses a flip-grinding method to process all burrs at once. The flip-grinding method will not be described in detail here, but will be introduced in detail in subsequent embodiments.

[0134] The flip-grinding method refers to a method that can grind the surface of the valve seat to remove burrs.

[0135] Laser polishing methods include the following steps:

[0136] Step 10500: Identify the protrusion features from the image exposed at the abnormal location to determine the location of the protrusion.

[0137] The protrusion location refers to the actual location of the protrusion on the valve seat. From the abnormal position exposure image, the position of the protrusion feature in the image can be determined first. Then, combined with the reference point determined by the position in the image and the image scale when the image was taken, the protrusion location can be determined.

[0138] Step 10501: Determine the laser polishing path based on the protrusion position and protrusion contour range.

[0139] The laser polishing path refers to the optimal path for the valve seat to move when processing it using a laser polishing method. Once the location and contour of the protrusion are determined, the area to be polished by the laser can be defined. The system then generates a laser polishing path within this area, following a preset scanning pattern, which is a horizontal reciprocating laser scan (details omitted here). As the valve seat moves along the laser polishing path, the protruding portion on the valve seat can be removed quickly and completely.

[0140] Step 10502: Determine the laser polishing power based on the range of the raised contour.

[0141] Laser polishing power refers to the laser power set by the laser equipment when different protrusion features need to be polished. Normally, the larger the protrusion's contour range, the greater its thickness. Therefore, the laser polishing power is directly proportional to the protrusion's contour range; the laser polishing power increases as the protrusion's contour range increases. When the laser equipment operates at the laser polishing power, the emitted laser can precisely remove the protrusion within its contour range.

[0142] Step 10503: Control the clamping component 33 to clamp the valve seat and move it along the laser polishing path, and control the preset laser equipment to polish the protruding features at the protruding position with the laser polishing power.

[0143] The laser device is installed in the identification component 21 above the first detection station 24. The laser device is a pre-fixed device that can emit laser. Since the laser device itself cannot be moved, the valve seat is moved to the processing position that the laser device can process during grinding, so that the starting point of the laser grinding path coincides with the processing position to facilitate the correct grinding.

[0144] The flipping and smoothing method includes the following steps:

[0145] Step 10510: Identify all protrusion features from the image exposed at the abnormal location and determine the burr protrusion height of each protrusion feature.

[0146] The burr protrusion height refers to the straight-line length of the point where the burr protrudes from the valve seat and is furthest from the valve seat surface; it represents the height that needs to be removed by grinding. The burr protrusion height can be determined by image recognition of images exposed at abnormal locations. The image recognition method is existing technology and will not be elaborated here.

[0147] Step 10511: Select the maximum burr height from the burr protrusion heights.

[0148] The maximum burr height refers to the height of the burr protrusion with the longest straight line length among all the protruding features. It can be obtained by comparing the burr protrusion heights.

[0149] In this embodiment, when processing the burrs on the valve seat surface, the starting height for overall grinding is determined based on the maximum burr height.

[0150] Step 10512: Determine the starting height for flipping based on the maximum burr height, and determine the flipping and polishing force based on the maximum contour.

[0151] The starting height for flipping refers to the height at which the grinding disc on the first inspection station 24 is far away from the valve seat after the valve seat is flipped. It can be obtained by summing the maximum burr height and the preset redundancy height. The redundancy height is a positive number preset by the operator. The specific setting value is selected by the operator according to the actual situation, and will not be elaborated here.

[0152] The tumbling grinding force refers to the grinding force required for the grinding disc to completely remove a protrusion with the largest contour; it is the force applied by the grinding disc to the protruding burr. The tumbling grinding force corresponding to the largest contour can be found in the force correspondence table.

[0153] The force correspondence table is a data table that records different maximum contours and their corresponding flipping and grinding forces. It is a data table that is pre-collected and entered by technicians, and will not be elaborated on here.

[0154] The position of the grinding disc can be changed by controlling the first cylinder 221 to move the feeding plate 222. The grinding disc is preset on the feeding plate 222.

[0155] Step 10513: Control the clamping component 33 to clamp the valve seat and rotate it 180°, and control the height between the grinding disc and the valve seat preset on the first detection station 24 based on the starting height of the rotation.

[0156] Since the initial height of the flip is greater than the maximum burr height, the valve seat does not contact the grinding disc at this time.

[0157] Step 10514: Control the grinding disc to move relative to the valve seat with the rotation grinding force and the preset grinding path, and control the grinding disc to gradually approach the valve seat with the preset rising speed until the valve seat and the grinding disc come into contact, thus completing the grinding.

[0158] The rising speed refers to the speed at which the grinding disc moves upward toward the valve seat. It is a value preset by the operator and will not be elaborated here.

[0159] The lifting speed can be determined by controlling the lifting force of the first cylinder 221.

[0160] The grinding path is the path of the clamping component 33 reciprocating horizontally into and out of the first inspection station 24.

[0161] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
