Description

Technical Field

[0001] The invention relates to the field of detection technology, in particular to ejector pin detection equipment with automatic screening function. Background Art

[0002] The seat is an important facility related to the driving and riding comfort of the vehicle, among which the main driver's seat is more important, and the quality of the driver's seat design is directly related to the driving quality. A comfortable and easy-to-operate driver's seat can not only reduce the driver's fatigue, but also effectively reduce the occurrence of failures. When adjusting the seat, the seat adjuster is mainly used for adjustment.

[0003] After the seat adjuster is produced, it needs to be inspected for quality. However, the existing seat adjuster inspection equipment cannot automatically align the adjuster, and the placement process requires manual assistance, which not only increases the labor intensity when installing and fixing the adjuster, but also wastes a lot of time. In addition, during the inspection process, each inspection is carried out separately, and some require manual inspection, which is not only inaccurate, but also inefficient. Summary of the invention

[0004] The object of the present invention is to provide a ejector pin detection device with an automatic screening function to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a thimble detection device with automatic screening function, comprising a workpiece, the thimble detection device comprising a bracket, the bracket being equipped with a feeding mechanism, a thimble detection mechanism, an outer circle detection mechanism and a transfer mechanism, the transfer mechanism being located on one side of the feeding mechanism, the thimble detection mechanism and the outer circle detection mechanism, the workpiece being placed on the feeding mechanism, the transfer mechanism placing the workpiece on the thimble detection mechanism and the outer circle detection mechanism in sequence, the thimble detection mechanism detecting the surface of the workpiece, and the outer circle detection mechanism detecting whether there is a bulge on the surface of the workpiece. The transfer mechanism transfers the workpiece on the feeding mechanism to the ejector detection mechanism and the outer circle detection mechanism in turn. The ejector detection mechanism uses the ejector to lift the workpiece, and the ejector detection mechanism uses a sensor to detect defects on the workpiece surface. The outer circle detection mechanism performs outer circle detection on the cylindrical part of the workpiece to detect whether there is a bulge on the cylindrical part of the workpiece. After the workpiece detection is completed, the transfer mechanism transfers the workpiece from the outer circle detection mechanism to the slide rail, and the NG workpiece slides into the NG box, and the OK workpiece slides to the unloading area. Through the setting of the ejector detection mechanism and the outer circle detection mechanism, automatic detection of the workpiece is realized, which reduces labor and improves the detection efficiency of the workpiece.

[0006] A slideway is installed on one side of the outer circle detection mechanism on the bracket, and an NG box is installed below the slideway on one side of the bracket;

[0007] The loading mechanism includes a base plate, which is connected to the bracket, and two supporting cylinders and a pushing cylinder are installed under the base plate, and material rails are installed on the two supporting cylinders, and material belts are installed on both sides of the material rails. The workpiece is located above the material rails and below the two material belts, and an "L"-shaped support plate is installed on one side of the material rail, and a feeding cylinder is installed on the support plate, and a material shifting block is installed at one end of the feeding cylinder, and a shifting rod is rotatably installed at the middle part of one end of the material shifting block, and one end of the shifting rod is inserted into the center position of the workpiece under the drive of the feeding cylinder, and the pushing cylinder is located below one end of the material rail, and the cylinder rod of the pushing cylinder penetrates the material rail, and a pushing sleeve is installed on the top of the cylinder rod of the pushing cylinder. The slide is used to carry the unloading of workpieces. The slide is directed to the unloading area and the NG box according to the inspection results of the workpieces. The NG box is used to store workpieces that fail the inspection. The bottom plate is used to carry the supporting cylinder and the ejecting cylinder. The material rail is installed on the supporting cylinder. The supporting cylinder lifts the material rail upward. The ejecting cylinder ejects the workpiece in the material rail through the ejecting sleeve installed on the top, so that the workpiece moves to the outside of the material rail, which is convenient for the transfer mechanism to grab the workpiece. The support plate provides support for the installation of the feeding cylinder. The feeding cylinder pushes the workpiece forward through the pushing block to advance the workpiece, thereby realizing the loading of the workpiece.

[0008] A top plate is installed above the bottom plate, two reset cylinders are installed below the top plate, a stabilizing cylinder is installed on one side above the top plate, a pressure spring is installed on the cylinder rod of the stabilizing cylinder, the pressure spring is located below the top plate, and the pressure spring is located directly above the top plate. The top plate is installed on the bottom plate through a support plate, and the top plate provides support for the installation of the reset cylinder and the stabilizing cylinder. The reset cylinder is used to assist in resetting the material rail. When the material support cylinder lifts the material rail and the reset of the material support cylinder is stuck, the reset cylinder is actuated to push the material rail downward to achieve the reset of the material support cylinder, thereby avoiding the entire equipment being shut down for inspection due to the reset failure of the material support cylinder. Before the top plate lifts the workpiece upward, the stabilizing cylinder pushes the pressure spring downward to make one end of the pressure spring rest on the workpiece, and then the top plate is actuated, and the top plate and the stabilizing cylinder cooperate with each other to achieve the stable rise of the workpiece, thereby avoiding shaking of the workpiece when it is lifted by the top plate, and keeping the workpiece in a horizontal state, which is convenient for the workpiece to be grasped and transferred by the transfer mechanism.

[0009] The transfer mechanism comprises a vertical plate, a horizontal slide rail is mounted on the vertical plate, a carry slide is mounted on the horizontal slide rail, one end of the carry slide is connected to a push cylinder, and the push cylinder is mounted on the vertical plate;

[0010] Three groups of lower rails are vertically installed on the carry slide, and a pick-up and place slide is commonly installed on the three groups of lower rails. A pick-up and place cylinder is installed on the carry slide, and the cylinder rod of the pick-up and place cylinder is connected to the pick-up and place slide. A rotating cylinder is installed on the side of the pick-up and place slide close to the top-loading cylinder. Two clamping cylinders are installed on the pick-up and place slide, and a clamping cylinder is installed on the rotating cylinder. The clamping cylinder is used to transfer workpieces. The vertical plate provides support for the installation of the horizontal slide rail and the push cylinder. The carry slide is installed on the horizontal slide rail. The push cylinder makes the carry slide slide on the horizontal slide rail. The sliding of the carry slide transfers the clamping cylinder to the corresponding position, so that the clamping cylinder clamps or releases the workpiece, so that the workpiece is placed on the ejector detection mechanism or the outer circle detection mechanism by the clamping cylinder; the lower rail provides support for the installation of the pick-and-place slide. The pick-and-place slide moves in the vertical direction through the lower rail. The pick-and-place cylinder provides power for the up and down movement of the pick-and-place slide. The pick-and-place slide drives the clamping cylinder and the rotating cylinder to move up and down, and the rotating cylinder rotates the clamping cylinder;

[0011] During loading, the three clamping cylinders correspond to the ejector cylinder, the ejector pin detection mechanism and the outer circle detection mechanism respectively; when the pick-and-place slide moves downward, the clamping cylinder clamps the workpiece, the clamping cylinder on the rotating cylinder clamps the workpiece lifted by the ejector cylinder, and the remaining two clamping cylinders clamp the workpieces on the ejector pin detection mechanism and the outer circle detection mechanism respectively; then, the pick-and-place slide moves upward, and the carry slide moves forward driven by the push cylinder, so that the three clamping cylinders correspond to the ejector pin detection mechanism, the outer circle detection mechanism and the slideway respectively; then, the pick-and-place slide moves downward again, so that the clamping cylinder on the rotating cylinder places the workpiece on the ejector pin detection mechanism, and the remaining two clamping cylinders place the workpiece on the outer circle detection mechanism and the slideway respectively; after the workpiece is placed, the pick-and-place slide moves upward, and the carry slide is reset driven by the push cylinder, so that the three clamping cylinders correspond to the ejector cylinder, the ejector pin detection mechanism and the outer circle detection mechanism respectively again.

[0012] The ejector pin detection mechanism includes a holder and a side plate. The holder is located on one side of the feeding mechanism. A detection column is installed in the middle of the holder. The side plate is located on one side of the holder. A slide rail is installed on the side plate. A downward pressure cylinder is installed on the top of the side plate. The cylinder rod of the downward pressure cylinder is connected to the slide in the slide rail. A positioning plate is installed on the slide in the slide rail. A sensor is installed below the positioning plate. The holder is used to support the detection column. The detection column is used to place the workpiece. After the workpiece is placed on the detection column by the transfer mechanism, the downward pressure cylinder is activated, and the slide in the slide rail is pushed by the downward pressure cylinder. The slide moves downward, so that the sensor is driven downward by the positioning plate. The sensor performs defect detection on the surface of the workpiece and transmits the detection results to the control system.

[0013] A ejector component is installed in the detection column, and the ejector component lifts the workpiece upward;

[0014] A rotating disk is installed in the adjustment plate, an outer cylinder is sleeved on the outer side of the rotating part of the rotating disk, the outer cylinder is connected to the adjustment plate, a spiral feed slide is provided on the inner wall of the outer cylinder, and the two ends of the feed slide are connected by a vertical slide;

[0015] A middle column is installed in the middle of the rotating part of the rotating disk, a progress board is installed on the outer side of the middle column, the length of the progress board is less than the height of the carry-in slideway, a lower plate is installed at the lower end of the middle column, an upper plate is sleeved on the middle column, a guide block is installed on the outer wall of the upper plate, and the guide block is located in the carry-in slideway;

[0016] The upper plate is provided with a deflection slot, a transposition frame is installed in the deflection slot, and the transposition frame is arc-shaped;

[0017] A return spring is arranged between the lower plate and the upper plate, and a straight rail is provided on the lower plate at a position corresponding to the transposition frame;

[0018] The straight rail and the transposition frame are provided with a conducting rod, and the sensor is provided on the conducting rod. The ejector assembly is composed of an ejector, a mounting plate and a cylinder, the mounting plate is provided on the cylinder, and the ejector is fixed on the mounting plate. After the cylinder is actuated, the ejector lifts the product from the detection column. After the ejector assembly lifts the workpiece, the sensor detects the height of the workpiece to detect whether the workpiece is in a horizontal state. If the workpiece is not in a horizontal state, a production defect is detected on the workpiece.

[0019] The rotating disk includes a fixed part and a rotating part. The fixed part provides power for the rotation of the rotating part. The rotating part drives the middle column to rotate. The outer cylinder provides a basis for opening an advance slide. The advance slide cooperates with the guide block to make the upper plate move upward and away from the lower plate. The middle column drives the lower plate to rotate, and at the same time drives the upper plate to rotate through the progress plate. During the rotation of the upper plate, the upper plate cooperates with the guide block and the advance slide to make the upper plate move upward on the middle column.

[0020] The length of the progress plate is less than the height of the carry slide. The middle column uses the progress plate to drive the upper plate to move. The upper plate moves upward under the action of the guide block and the carry slide. After the height of the upper plate exceeds the length of the progress plate, the conduction rod continues to move the upper plate under the drive of the lower plate. The conduction rod applies pressure to the transposition frame on the upper plate, so that the upper plate continues to move along the carry slide. The upper plate rotates around the middle column. After the upper plate moves to the top of the carry slide, the upper plate rotates one scale. One scale is the distance between the two progress plates. When the conduction rod applies pressure to the transposition frame, due to the arc shape of the transposition frame, the conduction rod will move a certain distance in the straight rail under the guidance of the transposition frame. The position of the sensor is adjusted through the movement of the conduction rod. One end of the reset spring is fixed to the lower plate, and the other end is slidably connected to the upper plate. After the upper plate passes over the top of the advance slide, the reset spring pulls the upper plate downward. After the upper plate passes over the top of the advance slide, the position between the upper plate and the lower plate is fixed by the conduction rod. At this time, the rotating disk will stop briefly to provide time for the upper plate to reset. The upper plate is again mounted on the outside of several progress plates under the pull of the reset spring to provide a basis for the next rise.

[0021] Every time the position of the conduction rod is adjusted, the sensor's detection radius of the workpiece will change. By continuously adjusting the position of the sensor, detection of various positions of the workpiece can be achieved. The sensor is a distance measuring sensor. By adjusting the sensor, accurate detection of surface defects of the workpiece can be achieved. Every time the sensor adjusts its position, the control system will record the position once, thereby realizing the record of the sensor's detection radius. The control system records the rotation angle and rotation speed of the rotating disk. The control system combines the sensor's position record with the record of the rotating angle and speed of the rotating disk to obtain an accurate record of the workpiece surface position. When the sensor detects a defect, the detected defect data is combined with the position data of the workpiece surface to achieve accurate detection of surface defects of the workpiece, accurate positioning of the defect position, and accurate detection of the defect depth or defect protrusion height.

[0022] The ejector component is used to detect defects on the lower surface of the workpiece, and the position of the sensor is adjusted to detect defects on the upper surface of the workpiece. The ejector detection mechanism is set to detect defects on the upper and lower surfaces of the workpiece at the same time.

[0023] The transposition frame includes two semi-circular end plates and two semiconductor plates for bending and dredging. The two ends of a semiconductor are respectively connected to one end of the two end plates. The two semiconductor plates and the two end plates cooperate with each other to form a transposition frame. The two semiconductor plates are respectively connected to the control system. When a voltage is applied to one of the semiconductor plates, the control system detects the magnitude of the current generated by the other semiconductor plate, thereby realizing the detection of the bending degree of the transposition frame. When one semiconductor plate is bent, the other semiconductor plate is driven to bend through the two end plates, and the transposition frame bends to form an arc slideway; when a voltage is applied to one semiconductor plate, the transposition frame bends to the left, and voltage is applied to the other semiconductor plate, causing the transposition frame to bend to the right. The control system only applies voltage to one semiconductor plate at a time; when the transposition frame bends to the left, when the conduction rod moves to the top of the straight rail, the control system bends the transposition frame to the right, so that the conduction rod is again dredged to the other end of the straight rail by the transposition frame. By changing the bending direction of the transposition frame, the movement direction of the conduction rod is adjusted, thereby causing the conduction rod to drive the sensor to reciprocate. Each time a workpiece is detected, the sensor will move to one end of the straight rail driven by the conductive rod. When two workpieces are detected, the sensor will realize a reciprocating motion in the straight rail.

[0024] The outer circle detection mechanism includes a material seat and a support plate. A fixing plate is installed on the outer side of the lower end of the material seat. The structure of the material seat is the same as that of the detection column.

[0025] The support plate is installed on one side of the fixed plate, and the second slide rail slide is installed on the support plate. A pressure detection cylinder is installed on the upper end of the support plate. The pressure detection cylinder is connected to the slide in the second slide rail slide. The second slide rail slide is installed on the slide. A bearing plate is installed on the bearing plate. A sleeve is slidably installed on the bearing plate. A pressure sensor is installed above the sleeve. A pressure plate is installed above the bearing plate. A buffer spring is installed below the pressure plate. A top block is installed at the lower end of the buffer spring. The top block is connected to the pressure sensor. When the outer circle of the cylindrical part of the workpiece is detected, the pressure detection cylinder pushes the slide in the second slide rail slide downward, so that the sleeve is sleeved on the outer side of the cylinder of the workpiece. The pressure sensor detects the pressure received by the sleeve during the sleeve installation process. If there is a bulge in the cylindrical part of the workpiece, the sleeve is blocked during the sleeve installation process, so that the pressure detected by the pressure sensor increases, and then the bulge in the cylindrical part of the workpiece is detected. The buffer spring is used to buffer the pressure application process to prevent the sleeve from being rigidly sleeved with the cylindrical part of the workpiece.

[0026] The slideway is provided with a material discharge port, a baffle is installed on the material discharge port, a material discharge cylinder is rotatably installed under the slideway, and one end of the material discharge cylinder is rotatably connected to the baffle;

[0027] The NG box is provided with a feed pipe, and the feed pipe corresponds to the position of the baffle;

[0028] A replacement plate is mounted on the bracket, a slide rail is mounted on the replacement plate, a material discharge slide plate is mounted on the slide rail, one end of the slide is connected to the material discharge slide plate, a replacement cylinder is mounted on one end of the replacement plate, and the cylinder rod of the replacement cylinder is connected to the material discharge slide plate. If the workpiece is OK material, after the clamping cylinder places the workpiece on the slide, the workpiece slides directly to the material discharge area along the slide; if the workpiece is NG material, the discharge cylinder is activated, so that the baffle rotates under the drive of the discharge cylinder, so that the workpiece falls into the material discharge pipe, and then the workpiece enters the NG box; when the discharge cylinder is damaged, that is, the baffle cannot release the blockage of the material discharge port, if the workpiece is OK material, the workpiece slides along the slide; if the workpiece is NG material, the replacement cylinder is activated, and the material discharge slide plate drives the slide to move, so that the slide avoids the feed port of the material discharge pipe, so that the workpiece is directly put into the material discharge pipe by the clamping cylinder.

[0029] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0030] 1. The ejector detection mechanism uses sensors to detect defects on the workpiece surface, and the outer circle detection mechanism performs outer circle detection on the cylindrical part of the workpiece to detect whether there is a bulge on the cylindrical part of the workpiece. Through the detection of the outer circle detection mechanism and the ejector detection mechanism, automatic screening of the workpiece is realized. After the workpiece detection is completed, the transfer mechanism transfers the workpiece from the outer circle detection mechanism to the slide rail, and the NG workpiece slides into the NG box, and the OK workpiece slides into the unloading area. Through the setting of the ejector detection mechanism and the outer circle detection mechanism, automatic detection of the workpiece is realized, which reduces labor and improves the detection efficiency of the workpiece.

[0031] 2. The sensor is a distance measuring sensor. By adjusting the sensor, it can realize accurate detection of surface defects of workpieces. Every time the sensor adjusts its position, the control system will record the position once, thereby realizing the record of the sensor detection radius. The control system records the rotation angle and rotation speed of the rotating disk. The control system combines the position record of the sensor with the record of the rotation angle and speed of the rotating disk to obtain an accurate record of the surface position of the workpiece. When the sensor detects a defect, the detected defect data is combined with the position data of the workpiece surface to realize accurate detection of surface defects of the workpiece, accurate positioning of the defect position, and accurate detection of the defect depth or defect protrusion height.

A rotating cylinder 507 is installed on the side of the pick-up and placement slide 505 close to the top cylinder 207. Two clamping cylinders 508 are installed on the pick-up and placement slide 505, and a clamping cylinder 508 is installed on the rotating cylinder 507. The clamping cylinder 508 is used to transfer the workpiece 6.

[0061] The rotating cylinder 507 is used to adjust the posture of the clamping cylinder 508 so that the clamping cylinder 508 rotates. When the workpiece 6 is on the material rail 209, it is in an inverted state, which is convenient for loading the workpiece 6. After the clamping cylinder 508 grabs the workpiece 6, the rotating cylinder 507 drives the clamping cylinder 508 to rotate, so that the workpiece 6 rotates 180°, thereby facilitating the subsequent loading of the workpiece 6 and the transfer of the workstations (the workstations are the ejector detection mechanism 3 and the outer circle detection mechanism 4).

[0062] The vertical plate 501 provides support for the installation of the horizontal slide rail 502 and the push cylinder 506. The carry slide 503 is installed on the horizontal slide rail 502. The push cylinder 506 makes the carry slide 503 slide on the horizontal slide rail 502. Through the sliding of the carry slide 503, the clamping cylinder 508 is transferred to the corresponding position, so that the clamping cylinder 508 clamps or releases the workpiece 6, so that the workpiece 6 is placed on the ejector detection mechanism 3 or the outer circle detection mechanism 4 by the clamping cylinder 508; the lower slide rail provides support for the installation of the pick-up and place slide 505. The pick-up and place slide 505 moves in the vertical direction through the lower slide rail. The pick-up and place cylinder 504 provides power for the up and down movement of the pick-up and place slide 505. The pick-up and place slide 505 drives the clamping cylinder 508 and the rotating cylinder 507 to move up and down, and the rotating cylinder 507 rotates the clamping cylinder 508;

[0063] During loading, the three clamping cylinders 508 correspond to the ejection cylinder 207, the ejector pin detection mechanism 3 and the outer circle detection mechanism 4 respectively. When the pick-up and placement slide 505 moves downward, the clamping cylinder 508 clamps the workpiece 6. The clamping cylinder 508 on the rotating cylinder 507 clamps the workpiece 6 lifted by the ejection cylinder 207. The remaining two clamping cylinders 508 clamp the workpiece 6 on the ejector pin detection mechanism 3 and the outer circle detection mechanism 4 respectively. After that, the pick-up and placement slide 505 moves upward, and the carrying slide 503 moves forward under the drive of the pushing cylinder 506, so that the three clamping cylinders 508 correspond to the ejection cylinder 207 and the outer circle detection mechanism 4 respectively. Needle detection mechanism 3, outer circle detection mechanism 4 and slideway 102, then, the pick-up and place slide plate 505 moves downward again, so that the clamping cylinder 508 on the rotating cylinder 507 places the workpiece 6 on the ejector needle detection mechanism 3, and the remaining two clamping cylinders 508 place the workpiece 6 on the outer circle detection mechanism 4 and the slideway 102 respectively. After the workpiece 6 is placed, the pick-up and place slide plate 505 moves upward, and the carry slide plate 503 is reset under the drive of the push cylinder 506, so that the three clamping cylinders 508 correspond to the ejector cylinder 207, the ejector needle detection mechanism 3 and the outer circle detection mechanism 4 respectively again.

[0064] The ejector detection mechanism 3 includes a holder 301 and a side plate 302. The holder 301 is located on one side of the feeding mechanism 2. A detection column is installed in the middle of the holder 301. The side plate 302 is located on one side of the holder 301. A slide plate is installed on the side plate 302. A pressing cylinder 303 is installed on the top of the side plate 302. The cylinder rod of the pressing cylinder 303 is connected to the slide plate in the slide plate. A positioning plate 304 is installed on the slide plate in the slide plate. Six sensors 305 are installed below the positioning plate 304. The holder 301 is used to support the detection column. The detection column is used to place the workpiece 6. After the workpiece 6 is placed on the detection column by the transfer mechanism 5, the pressing cylinder 303 is actuated, and the slide plate in the slide plate is pushed by the pressing cylinder 303. The slide plate moves downward, so that the sensor 305 is driven downward by the positioning plate 304. The sensor 305 performs defect detection on the surface of the workpiece 6 and transmits the detection result to the control system.

[0065] An ejector component is installed in the detection column, and the ejector component lifts the workpiece 6 upward;

[0066] A rotating disk 306 is installed in the adjustment plate 304. An outer cylinder 307 is sleeved on the outer side of the rotating part of the rotating disk 306. The outer cylinder 307 is connected to the adjustment plate 304. A spiral feed slide 308 is provided on the inner wall of the outer cylinder 307. The two ends of the feed slide 308 are connected by a vertical slide.

[0067] A middle column 311 is installed in the middle of the rotating part of the rotating disk 306, and a progress board 312 is installed on the outer side of the middle column 311. The length of the progress board 312 is less than the height of the carry-in slide 308. A lower plate 310 is installed at the lower end of the middle column 311. An upper plate 309 is sleeved on the middle column 311. A guide block is installed on the outer wall of the upper plate 309. The guide block is located in the carry-in slide 308.

[0068] Six deflection slots are provided on the upper plate 309, and a transposition frame 314 is installed in the deflection slots. The transposition frame 314 is arc-shaped;

[0069] A return spring 313 is provided between the lower plate 310 and the upper plate 309, and a straight rail 315 is provided on the lower plate 310 at a position corresponding to the transposition frame 314;

[0070] A conduction rod is installed in the straight rail 315 and the transposition frame 314, and the conduction rod is slidably connected with the straight rail 315, and the sensor 305 is installed on the conduction rod. When there is no rotation between the upper plate 309 and the lower plate 310, the conduction rod is clamped by the upper plate 309 and the lower plate 310, so that the conduction rod will not be affected by the centrifugal force and move on the straight rail 315 and the transposition frame 314.

[0071] The ejector assembly consists of an ejector, a mounting plate and a cylinder. The mounting plate is installed on the cylinder, and the ejector is fixed on the mounting plate. After the cylinder is actuated, the ejector lifts the product from the detection column. After the ejector assembly lifts the workpiece 6, the sensor 305 detects the height of the workpiece 6 to detect whether the workpiece 6 is in a horizontal state. If the workpiece 6 is not in a horizontal state, it is detected that there is a production defect on the workpiece 6.

[0072] The rotating disk 306 includes a fixed component and a rotating component. The fixed component provides power for the rotation of the rotating component. The rotating component drives the middle column 311 to rotate. The outer cylinder 307 provides a basis for opening the carry slide 308. The carry slide 308 cooperates with the guide block to make the upper plate 309 move upward, so that the upper plate 309 is away from the lower plate 310; the middle column 311 drives the lower plate 310 to rotate, and at the same time drives the upper plate 309 to rotate through the progress plate 312. During the rotation of the upper plate 309, the upper plate 309 cooperates with the carry slide 308 using the guide block to make the upper plate 309 move upward on the middle column 311;

[0073] The length of the progress board 312 is less than the height of the carry-in slide 308. The middle column 311 uses the progress board 312 to drive the upper board 309 to move. The upper board 309 moves upward under the action of the guide block and the carry-in slide 308. After the height of the upper board 309 exceeds the length of the progress board 312, the transmission rod continues to move the upper board 309 under the drive of the lower board 310, and the transmission rod applies pressure to the transposition frame 314 on the upper board 309, so that the upper board 309 continues to move along the carry-in slide. 308 moves, the upper plate 309 rotates around the middle column 311, and after the upper plate 309 moves to the top of the advance slide 308, the upper plate 309 rotates one scale, and one scale is the distance between the two progress plates 312. When the conduction rod applies pressure to the transposition frame 314, since the transposition frame 314 is arc-shaped, the conduction rod will move a certain distance in the straight rail 315 under the guidance of the transposition frame 314, and the position of the sensor 305 can be adjusted through the movement of the conduction rod. One end of the return spring 313 is fixed to the lower plate 310, and the other end is slidably connected to the upper plate 309. After the upper plate 309 passes over the top of the advance slide 308, the return spring 313 pulls the upper plate 309 downward. After the upper plate 309 passes over the top of the advance slide 308, the position between the upper plate 309 and the lower plate 310 is fixed by the conduction rod. At this time, the rotating disk 306 will stop briefly to provide time for the upper plate 309 to reset. The upper plate 309 is again mounted on the outside of the plurality of progress plates 312 under the pull of the return spring 313 to provide a basis for the next rise.

[0074] Every time the position of the conduction rod is adjusted, the detection radius of the workpiece 6 by the sensor 305 will change. By continuously adjusting the position of the sensor 305, the detection of various positions of the workpiece 6 can be achieved. The sensor 305 is a distance measuring sensor. By adjusting the sensor 305, accurate detection of surface defects of the workpiece 6 can be achieved; every time the sensor 305 adjusts its position, the control system will record the position once, thereby realizing the record of the detection radius of the sensor 305. The control system records the rotation angle and rotation speed of the rotating disk 306. The control system combines the position record of the sensor 305 with the record of the rotation angle and speed of the rotating disk 306 to obtain an accurate record of the surface position of the workpiece 6. When the sensor 305 detects a defect, the detected defect data is combined with the position data of the surface of the workpiece 6 to realize accurate detection of surface defects of the workpiece 6, accurate positioning of the defect position, and accurate detection of the defect depth or defect protrusion height.

[0075] The transposition frame 314 includes two semi-circular end plates and two semiconductor plates for bending and dredging. The two ends of a semiconductor are respectively connected to one end of the two end plates. The two semiconductor plates and the two end plates cooperate with each other to form the transposition frame 314. The two semiconductor plates are respectively connected to the control system. When voltage is applied to one of the semiconductor plates, the control system detects the magnitude of the current generated by the other semiconductor plate, thereby detecting the degree of bending of the transposition frame 314. When one semiconductor plate bends, the other semiconductor plate is driven to bend through the two end plates, and the transposition frame 314 bends to form an arc-shaped slideway; when voltage is applied to one semiconductor plate, the transposition frame 314 bends to the left, and voltage is applied to the other semiconductor plate, causing the transposition frame 314 to bend to the right. The control system applies voltage to only one semiconductor plate at a time; when the transposition frame 314 bends to the left, when the conduction rod moves to the top of the straight rail 315, the control system bends the transposition frame 314 to the right, so that the conduction rod is again guided to the other end of the straight rail 315 by the transposition frame 314. By changing the bending direction of the transposition frame 314, the movement direction of the conduction rod is adjusted, and the conduction rod drives the sensor 305 to reciprocate. Each time a workpiece 6 is detected, the sensor 305 will move to one end of the straight rail 315 driven by the conductive rod. When two workpieces 6 are detected, the sensor 305 will realize a reciprocating motion in the straight rail 315.

[0076] The outer circle detection mechanism 4 includes a material seat 401 and a support plate 402. A fixing plate is installed on the outer side of the lower end of the material seat 401. The structure of the material seat 401 is the same as that of the detection column.

[0077] The support plate 402 is installed on one side of the fixed plate, and a second slide rail slide plate is installed on the support plate 402. A pressure inspection cylinder 403 is installed on the upper end of the support plate 402, and the pressure inspection cylinder 403 is connected to the slide in the second slide rail slide plate. A bearing plate is installed on the second slide rail slide plate, and a sleeve 406 is slidably installed on the bearing plate. A pressure sensor 405 is installed above the sleeve 406. A pressure plate is installed above the bearing plate, and a buffer spring 404 is installed below the pressure plate. A top block is installed at the lower end of the buffer spring 404, and the top block is connected to the pressure sensor 405. When the outer circle of the cylindrical part of the workpiece 6 is detected, the pressure detection cylinder 403 pushes the slide in the second slide rail slide to move downward, so that the sleeve 406 is sleeved on the outer side of the cylinder of the workpiece 6, and the pressure sensor 405 detects the pressure received by the sleeve 406 during the sleeve installation process. If there is a bulge in the cylindrical part of the workpiece 6, the sleeve 406 is blocked during the sleeve installation process, so that the pressure detected by the pressure sensor 405 increases, and then the bulge is detected in the cylindrical part of the workpiece 6. The buffer spring 404 is used to buffer the pressure application process to prevent the sleeve 406 from being rigidly sleeved with the cylindrical part of the workpiece 6.

[0078] Working principle of the present invention:

[0079] The workpiece 6 is located above the material rail 209 and below the two material belts 210. The workpiece 6 is placed on the material rail 209. An "L"-shaped support plate is installed on one side of the material rail 209. A feed cylinder 206 is installed on the support plate. A material shifting block 211 is installed at one end of the feed cylinder 206. A lever is rotatably installed at the middle of one end of the material shifting block 211. The lever rotates unidirectionally on the material shifting block 211. When the lever pulls the workpiece 6, the lever does not rotate on the material shifting block. When the lever is pushed back by the material shifting block, the lever rotates on the material shifting block, so that the lever is pulled out of one workpiece 6.

[0080] One end of the lever is inserted into the center position of the workpiece 6 under the drive of the feed cylinder 206, the cylinder rod of the feed cylinder 206 is retracted, the lever pulls the workpiece 6 forward one workstation, the cylinder rod of the feed cylinder 206 is extended, the lever is pulled out of the current workpiece 6 and enters the next workpiece 6, when the cylinder rod of the feed cylinder 206 is retracted again, the lever completely enters the workpiece 6 and pulls the workpiece 6 forward.

[0081] The supporting cylinder 208 lifts the material rail 209 upwards, and the pushing cylinder 207 pushes out the workpiece 6 in the material rail 209 through the pushing sleeve installed on the top, so that the workpiece 6 moves to the outside of the material rail 209, which is convenient for the transfer mechanism 5 to grab the workpiece. Before the pushing cylinder 207 lifts the workpiece 6 upwards, the stabilizing cylinder 202 pushes the pressure spring 203 downwards, so that one end of the pressure spring 203 rests on the workpiece 6. After that, the pushing cylinder 207 is actuated, and the pushing cylinder 207 and the stabilizing cylinder 202 cooperate with each other to achieve stable ascent of the workpiece 6, avoiding shaking of the workpiece 6 when it is lifted by the pushing cylinder 207, so that the workpiece 6 remains in a horizontal state, which is convenient for the workpiece 6 to be grabbed and transferred by the transfer mechanism 5.

[0082] During loading, the three clamping cylinders 508 correspond to the ejection cylinder 207, the ejector pin detection mechanism 3 and the outer circle detection mechanism 4 respectively. When the pick-up and placement slide 505 moves downward, the clamping cylinder 508 clamps the workpiece 6. The clamping cylinder 508 on the rotating cylinder 507 clamps the workpiece 6 lifted by the ejection cylinder 207. The remaining two clamping cylinders 508 clamp the workpiece 6 on the ejector pin detection mechanism 3 and the outer circle detection mechanism 4 respectively. After that, the pick-up and placement slide 505 moves upward, and the carrying slide 503 moves forward under the drive of the pushing cylinder 506, so that the three clamping cylinders 508 correspond to the ejection cylinder 207 and the outer circle detection mechanism 4 respectively. Needle detection mechanism 3, outer circle detection mechanism 4 and slideway 102, then, the pick-up and place slide plate 505 moves downward again, so that the clamping cylinder 508 on the rotating cylinder 507 places the workpiece 6 on the ejector needle detection mechanism 3, and the remaining two clamping cylinders 508 place the workpiece 6 on the outer circle detection mechanism 4 and the slideway 102 respectively. After the workpiece 6 is placed, the pick-up and place slide plate 505 moves upward, and the carry slide plate 503 is reset under the drive of the push cylinder 506, so that the three clamping cylinders 508 correspond to the ejector cylinder 207, the ejector needle detection mechanism 3 and the outer circle detection mechanism 4 respectively again.

[0083] After the workpiece 6 is placed on the detection column by the transfer mechanism 5, the downward pressure cylinder 303 is actuated, and the slide in the slide rail is pushed by the downward pressure cylinder 303. The slide moves downward, causing the sensor 305 to be driven downward by the adjustment plate 304. The sensor 305 performs defect detection on the surface of the workpiece 6 and transmits the detection results to the control system.

[0084] A ejector component is installed in the detection column, and the ejector component lifts the workpiece 6 upward; the ejector component is composed of an ejector, a mounting plate and a cylinder, the mounting plate is installed on the cylinder, and the ejector is fixed on the mounting plate. After the cylinder is actuated, the ejector lifts the product from the detection column. After the ejector component lifts the workpiece 6, the sensor 305 detects the height of the workpiece 6 to detect whether the workpiece 6 is in a horizontal state. If the workpiece 6 is not in a horizontal state, it is detected that there is a production defect on the workpiece 6.

[0085] The rotating disk 306 includes a fixed component and a rotating component. The fixed component provides power for the rotation of the rotating component. The rotating component drives the middle column 311 to rotate. The outer cylinder 307 provides a basis for opening the carry slide 308. The carry slide 308 cooperates with the guide block to make the upper plate 309 move upward, so that the upper plate 309 is away from the lower plate 310; the middle column 311 drives the lower plate 310 to rotate, and at the same time drives the upper plate 309 to rotate through the progress plate 312. During the rotation of the upper plate 309, the upper plate 309 cooperates with the carry slide 308 using the guide block to make the upper plate 309 move upward on the middle column 311;

[0086] The length of the progress board 312 is less than the height of the carry-in slide 308. The middle column 311 uses the progress board 312 to drive the upper board 309 to move. The upper board 309 moves upward under the action of the guide block and the carry-in slide 308. After the height of the upper board 309 exceeds the length of the progress board 312, the transmission rod continues to move the upper board 309 under the drive of the lower board 310, and the transmission rod applies pressure to the transposition frame 314 on the upper board 309, so that the upper board 309 continues to move along the carry-in slide. 308 moves, the upper plate 309 rotates around the middle column 311, and after the upper plate 309 moves to the top of the advance slide 308, the upper plate 309 rotates one scale, and one scale is the distance between the two progress plates 312. When the conduction rod applies pressure to the transposition frame 314, since the transposition frame 314 is arc-shaped, the conduction rod will move a certain distance in the straight rail 315 under the guidance of the transposition frame 314, and the position of the sensor 305 can be adjusted through the movement of the conduction rod. One end of the return spring 313 is fixed to the lower plate 310, and the other end is slidably connected to the upper plate 309. After the upper plate 309 passes over the top of the advance slide 308, the return spring 313 pulls the upper plate 309 downward. After the upper plate 309 passes over the top of the advance slide 308, the position between the upper plate 309 and the lower plate 310 is fixed by the conduction rod. At this time, the rotating disk 306 will stop briefly to provide time for the upper plate 309 to reset. The upper plate 309 is again mounted on the outside of the plurality of progress plates 312 under the pull of the return spring 313 to provide a basis for the next rise.

[0087] Every time the position of the conduction rod is adjusted, the detection radius of the workpiece 6 by the sensor 305 will change. By continuously adjusting the position of the sensor 305, the detection of various positions of the workpiece 6 can be achieved. The sensor 305 is a distance measuring sensor. By adjusting the sensor 305, accurate detection of surface defects of the workpiece 6 can be achieved; every time the sensor 305 adjusts its position, the control system will record the position once, thereby realizing the record of the detection radius of the sensor 305. The control system records the rotation angle and rotation speed of the rotating disk 306. The control system combines the position record of the sensor 305 with the record of the rotation angle and speed of the rotating disk 306 to obtain an accurate record of the surface position of the workpiece 6. When the sensor 305 detects a defect, the detected defect data is combined with the position data of the surface of the workpiece 6 to realize accurate detection of surface defects of the workpiece 6, accurate positioning of the defect position, and accurate detection of the defect depth or defect protrusion height.

[0088] After the ejector pin detection mechanism 3 completes the detection, the workpiece 6 is rotated by the transfer mechanism 5 onto the outer circle detection mechanism 4, and the workpiece 6 is placed on the material holder 401. When the outer circle of the cylindrical part of the workpiece 6 is detected, the pressure detection cylinder 403 pushes the slide in the second slide rail slide to move downward, so that the sleeve 406 is sleeved on the outer side of the cylinder of the workpiece 6. The pressure sensor 405 detects the pressure applied to the sleeve 406 during the sleeve installation process. If there is a bulge on the cylindrical part of the workpiece 6, the sleeve 406 is obstructed during the sleeve installation process, which increases the pressure detected by the pressure sensor 405, and then detects the presence of a bulge on the cylindrical part of the workpiece 6.

[0089] If the workpiece 6 is OK material, after the clamping cylinder 508 places the workpiece 6 on the slide 102, the workpiece 6 slides directly to the unloading area along the slide 102; if the workpiece 6 is NG material, the unloading cylinder 103 is actuated, so that the baffle rotates under the drive of the unloading cylinder 103, so that the workpiece 6 falls into the unloading pipe 104, and then the workpiece 6 enters the NG box; when the unloading cylinder 103 is damaged, that is, the baffle cannot release the blockage of the unloading port, if the workpiece 6 is OK material, the workpiece 6 slides along the slide 102; if the workpiece 6 is NG material, the replacement cylinder 105 is actuated, and the unloading slide 106 drives the slide 102 to move, so that the slide 102 avoids the feed port of the unloading pipe 104, so that the workpiece 6 is directly put into the unloading pipe 104 by the clamping cylinder 508.
