[0017] 2. The multi-angle workpiece inspection equipment emulating human vision supports the workpiece to be inspected by a turntable, and uses a cylinder to drive the push plate to slide on the turntable, so that the soft pad and the limit rubber strip contact the workpiece, and then push the workpiece to move in the center of the turntable, and the multi-directional pushing of the soft pad can ensure the accuracy of the position of the workpiece on the turntable.

[0019] Fourth, the multi-angle workpiece detection equipment emulating human vision rotates the turntable through the second motor. With the setting of the connecting ring plate, it can synchronously drive the workpiece and the extrusion locking part to rotate, so as to change the angle of the workpiece and perform multi-angle image acquisition.

The opening and closing member 22 includes a first motor 221, which is fixedly mounted on the top of the box body 21. A screw rod 222 is fixedly connected to the end of the output shaft of the first motor 221. The end of the screw rod 222 away from the first motor 221 is rotatably connected to a stopper 223. The bottom surface of the stopper 223 is fixed to the top of the box body 21. A moving block 224 is threadedly driven on the outer edge surface of the screw rod 222.

[0035] Among them, the centering device 3 includes a driving member 31, the bottom surface of the driving member 31 is connected to the bottom surface of the inner cavity of the detection box 2, and the driving member 31 is evenly distributed on the bottom surface of the inner cavity of the detection box 2, and a fitting push member 32 is installed at the end of the driving member 31, and the bottom surface of the fitting push member 32 is in contact with the top of the rotator 4.

[0036] During operation, the workpiece is first placed on the rotator 4, and the driving member 31 is started to push the fitting push member 32 to move toward the workpiece. Since the driving members 31 are evenly distributed on the bottom surface of the inner cavity of the box body 21, the fitting push member 32 can push the workpiece from multiple directions at the same time to ensure that the workpiece is centered on the rotator 4.

After the inspection is completed, the first motor 221 is started, driving the screw rod 222 to rotate, so that the moving block 224 moves along the axial direction of the screw rod 222, driving the box door 23 to slide along the slide groove 24, so as to open the inspection box and take out the workpiece.

[0037] The second embodiment is based on the first embodiment. Figures 3 to 8As shown, the driving member 31 includes a fixing plate 311, the bottom surface of the fixing plate 311 is fixed to the bottom surface of the inner cavity of the box body 21, a cylinder 312 is fixedly installed on one side surface of the fixing plate 311, the output shaft end of the cylinder 312 is connected to the fitting push member 32, the fitting push member 32 includes a push plate 321, one side surface of the push plate 321 is fixed to the output shaft end of the cylinder 312, the bottom surface of the push plate 321 slides with the top of the rotator 4, a soft pad 322 is fixedly installed on the side surface of the push plate 321 away from the cylinder 312, the soft pad 322 is arranged at intervals, and the inner arc surface of the soft pad 322 is fixed A limiting rubber strip 323 is embedded, and an arc-shaped stopper 324 is fixedly connected to the surface of one side of the push plate 321 close to the soft pad strip 322. The outer edge surface of the arc-shaped stopper 324 contacts the surface of the limiting rubber strip 323 close to the push plate 321. The rotator 4 includes a second motor 41. The top of the second motor 41 is fixed to the bottom surface of the box body 21. The output shaft of the second motor 41 passes through the box body 21 and rotates with the inner wall of the bottom surface of the box body 21. The end of the output shaft of the second motor 41 is fixedly connected to a turntable 42. The bottom surface of the turntable 42 rotates with the bottom surface of the inner cavity of the box body 21. A limiting slide plate 43 is fixedly installed on the bottom surface of the turntable 42. A roller 44 is adaptively rotated on the inner wall of the slide plate 43, and the outer edge surfaces of the limiting slide plate 43 and the roller 44 slide with the bottom surface of the inner cavity of the box body 21, and the bottom surface of the push plate 321 slides with the top of the turntable 42. The turntable 42 supports the workpiece to be inspected, and the cylinder 312 is used to drive the push plate 321 to slide on the turntable 42, so that the soft pad strip 322 and the limiting rubber strip 323 contact the workpiece, and then push the workpiece to move in the center of the turntable 42. The multi-directional pushing of the soft pad strip 322 can ensure the accuracy of the position of the workpiece on the turntable 42. In addition, by using the setting of the soft pad strip 322 and the limiting rubber strip 323, when contacting the workpiece Extrusion deformation is generated, and the material properties of the soft pad strip 322 and the limiting rubber strip 323 are combined to prevent damage to the workpiece. The arc-shaped stop block 324 is used to limit the deformation state of the limiting rubber strip 323 to ensure accuracy when pushing the workpiece to move. The turntable 42 is rotated by the second motor 41, and the connection ring plate 54 is combined to synchronously drive the workpiece and the extrusion locking member 52 to rotate, so as to change the angle of the workpiece and perform multi-angle image acquisition.

[0038] During operation, when the workpiece is placed on the turntable 42, the output shaft of the cylinder 312 extends, pushing the push plate 321 to move toward the workpiece, and the soft pad 322 on the push plate 321 first contacts the workpiece. Since the material of the soft pad 322 is soft and elastic, it can adapt to the surfaces of workpieces of different shapes and sizes, reducing friction and wear. The limiting rubber strip 323 inside the soft pad 322 plays a further limiting and fixing role, ensuring that the push plate 321 will not cause the workpiece to slide or deflect when pushing the workpiece. At the same time, the arc-shaped stopper 324 contacts the limiting rubber strip 323 to provide a stable support structure for the push plate 321 to prevent shaking during the pushing process. With the continuous push of the cylinder 312, the workpiece is evenly pushed to the center position of the turntable 42 to achieve the centering of the workpiece. When the workpiece is centered, the lock 5 is used to lock the workpiece, and then the cylinder 312 contracts to drive the push plate 321 to move, releasing the push on the workpiece, and starting the second motor 41 to drive the turntable 42 to rotate. The limiting slide plate 43 and the roller 44 at the bottom of the turntable 42 slide with the bottom surface of the inner cavity of the box body 21 to ensure the stability and smoothness of the turntable 42 during rotation. After the detection is completed, the second motor 41 stops working and the turntable 42 stops rotating. At this time, the hydraulic device 51 contracts to release the lock on the workpiece, open the box door 23, and take out the workpiece that has been detected.

[0039] The third embodiment is based on the first and second embodiments. Figures 9 to 12 As shown, the locker 5 includes a fixing frame 53, both sides of the fixing frame 53 are fixed to the inner cavity side surfaces of the box body 21, a hydraulic device 51 is fixedly installed on the top of the fixing frame 53, the output shaft of the hydraulic device 51 passes through the fixing frame 53 and slides with the inner wall of the fixing frame 53, the end of the output shaft of the hydraulic device 51 is fixedly connected to a connecting ring plate 54, and the bottom surface of the connecting ring plate 54 is rotatably connected to an extrusion locking member 52;

[0040] The extrusion locking member 52 includes a connecting plate 521, the top of the connecting plate 521 rotates with the bottom surface of the connecting ring plate 54, a cone 522 is fixedly installed on the bottom surface of the connecting plate 521, and a plurality of cones 522 are arranged, which are evenly spaced on the bottom surface of the connecting plate 521. A fixing rod 524 is fixedly installed in the middle of the bottom surface of the connecting plate 521, and a positioning block 525 is slidably sleeved on the bottom end of the outer edge surface of the fixing rod 524. The top of the positioning block 525 is fixedly connected with a sleeve spring 526, which is movably sleeved on the outside of the fixing rod 524, and the top of the sleeve spring 526 is fixed to the bottom surface of the connecting plate 521. An elastic rubber block 523 is fixedly connected between adjacent cones 522, and the top of the elastic rubber block 523 is fixed to the bottom surface of the connecting plate 521. The inner surface of the cone 522 is fixedly connected to the outer surface of the fixing rod 524. A limiting groove 528 is provided on the side surface, and a limiting slider 527 is fixedly installed on the outer edge surface of the positioning pressure block 525. The outer edge surface of the limiting slider 527 slides in accordance with the inner wall of the limiting groove 528. The connecting ring plate 54 and the extrusion locking member 52 are driven downward by the hydraulic device 51 to make the extrusion locking member 52 contact with the top of the workpiece. In cooperation with the sliding of the positioning pressure block 525 in the cone 522, the extrusion sleeve spring 526 is deformed, and in cooperation with the sliding of the positioning pressure block 525 outside the fixed rod 524, the elastic rubber block 523 contacts with the top of the workpiece in cooperation with the positioning pressure block 525. At the same time, since the elastic rubber block 523 is deformed under pressure, the locking effect on the workpiece can be further increased to prevent the workpiece from shifting during rotation, thereby ensuring the image acquisition accuracy of detection and recognition.

[0041] During operation, when it is necessary to lock the workpiece, the hydraulic device 51 is started, and its output shaft moves downward to drive the connecting ring plate 54 to move downward synchronously, thereby driving the extrusion locking member 52 to perform a locking operation. The cone 522 enables a larger extrusion force to be generated when contacting the workpiece, thereby achieving locking of the workpiece. The elastic rubber block 523 between the cones 522 plays a buffering role to prevent direct hard contact from causing damage to the workpiece. The positioning pressure block 525 is connected to the connecting plate 521 through a sleeve spring 526. The sleeve spring 526 provides a certain elastic force, so that the positioning pressure block 525 can be close to the surface of the workpiece. When the cone 522 is subjected to the reaction force of the object, the positioning pressure block 525 slides in the limiting groove 528 through the limiting slider 527.

[0042] The working principle of the multi-angle workpiece detection equipment simulating human vision is described in detail below.

[0043] When in use, the workpiece is first placed on the rotatable disk 42 of the rotator, and the output shaft of the cylinder 312 is extended to push the push plate 321 to move toward the workpiece. The soft pad 322 on the push plate 321 first contacts the workpiece. Since the material of the soft pad 322 is soft and elastic, it can adapt to the surfaces of workpieces of different shapes and sizes to reduce friction and wear. The limiting rubber strip 323 inside the soft pad 322 plays a further limiting and fixing role to ensure that the push plate 321 does not cause the workpiece to slide or deflect when pushing the workpiece. At the same time, the arc stopper 324 and the limiting rubber strip 32 The three-phase contact provides a stable support structure for the push plate 321 to prevent shaking during the pushing process. With the continuous pushing of the cylinder 312, the workpiece is evenly pushed to the center position of the turntable 42 to achieve the centering of the workpiece. At the same time, the hydraulic device 51 is started, and its output shaft moves downward to drive the connecting ring plate 54 to move downward synchronously, thereby driving the extrusion locking member 52 to perform the locking operation. The cone 522 enables a large extrusion force to be generated when contacting the workpiece, thereby achieving the locking of the workpiece. The elastic rubber block 523 between the cones 522 plays a buffering role to prevent direct hard contact The workpiece is damaged. The positioning block 525 is connected to the connecting plate 521 through the sleeve spring 526. The sleeve spring 526 provides a certain elastic force, so that the positioning block 525 can be close to the surface of the workpiece, further assisting the workpiece to be centered and locked in position. At this time, the cylinder 312 contracts, driving the push plate 321 to move, releasing the push on the workpiece, and the second motor 41 starts to work, driving the turntable 42 to rotate. The limiting slide plate 43 and the roller 44 at the bottom of the turntable 42 slide with the bottom surface of the inner cavity of the box body 21 to ensure the stability and smoothness of the turntable 42 during rotation. During the rotation process, the industrial The camera 6 continuously collects images of the workpiece surface.
