The flexible clamping mechanism is installed on the mechanical arm of the clamping robot 40. The clamping robot 40 is used to drive the flexible clamping mechanism to move so that the flexible clamping mechanism can adsorb and grasp the metal spacer on the lifting mechanism.

[0037] The feeding system also includes a feeding workbench 50, and the lifting mechanism is installed in the feeding workbench 50. The specific installation method can be a common installation method in the technical field, and no specific limitation is made here.

[0038] The lifting mechanism includes an electric cylinder 51, and a loading tray 52 is connected to the telescopic shaft of the electric cylinder 51. The electric cylinder 51 is used to drive the loading tray 52 to move up and down. The loading tray 52 is located on the loading workbench 50, and the metal spacer is placed on the loading tray 52. ​​The loading tray 52 is moved up to realize the upward movement of the metal spacer.

[0039] A loading shaft 54 ​​is vertically provided on the loading tray 52 , and a metal spacer passes through the loading shaft 54 ​​and is placed on the loading tray 52 . The loading shaft 54 ​​can limit the metal spacer to prevent the metal spacer from detaching from the loading tray 52 .

When the metal spacer moves up to a set height, the counter-fiber 53 will detect the metal spacer and send a signal to the PLC control system. The PLC control system will control the electric cylinder 51 to stop working, so that the metal spacer will stop moving up.

[0041] After the metal spacer moves up to the set height, the flexible clamping mechanism is driven by the clamping robot 40 to move, so that the flexible clamping mechanism adsorbs and clamps the metal spacer on the loading tray 52. ​​The clamping robot 40 can drive the adsorbed metal spacer to move and transfer the metal spacer to the image detection system and / or the blue light detection system for detection.

[0042] The flexible clamping mechanism comprises a clamping connecting plate 41 , on which a flange 42 is provided. The flange 42 is connected to the mechanical arm of the clamping robot 40 , so that the entire flexible clamping mechanism is connected to the mechanical arm of the clamping robot 40 .

The adapter plate is an integral part, including three support plates 44, and the angle between two adjacent support plates 44 is 120°; a bracket is connected to the support plate 44, and a suction cup 45 is connected to the bracket. There are three suction cups 45 in total, and the three suction cups 45 are symmetrically distributed. The midline points connecting the three suction cups 45 can form a circle, so that the three suction cups 45 can be symmetrically distributed on the metal spacer, so that the metal spacer is evenly stressed, and the circular metal spacer can be stably and effectively adsorbed.

[0045] The upper side plate 442 is connected to the support plate 44, and the connection position of the upper side plate 442 on the support plate 44 is adjustable; specifically, a long strip through hole 444 is provided on the upper side plate 442, and a connecting hole 445 is provided on the support plate 44. The upper side plate 442 fits the support plate 44, and the long strip through hole 444 can correspond to the connecting hole 445; by moving the entire bracket, the connecting hole 445 is made to correspond to different positions of the long strip through hole 444, so that the connection position of the bracket on the support plate 44 can be adjusted.

[0046] By adjusting the connection position of the bracket on the support plate 44, the diameter of the circle surrounded by the three suction cups 45 can be adjusted, so that metal spacers of different diameters can be adsorbed, making the flexible clamping mechanism of the utility model highly applicable, and can adsorb and clamp metal spacers of different diameters to meet the detection of metal spacers of different diameters.

[0047] The suction cup 45 is connected to the lower side plate 443, and the installation position of the suction cup 45 on the lower side plate 443 in the radial direction and the axial direction can be adjusted. The lower side plate 443 is provided with a U-shaped opening 446, and the suction cup 45 can be connected in the U-shaped opening 446 by bolts. By adjusting the connection position of the suction cup 45 in the U-shaped opening 446, the installation position of the suction cup 45 on the bracket in the radial direction can be adjusted. By moving the suction cup 45 up and down to adjust the connection position of the suction cup 45 with the U-shaped opening 446, the installation position of the suction cup 45 on the bracket in the axial direction can be adjusted.

[0048] By adjusting the radial and axial mounting positions of the suction cups 45 on the lower side plate 443, the diameter of the circle formed by the three suction cups 45 can be adjusted, so that metal spacers of different diameters can be adsorbed, making the flexible clamping mechanism of the utility model highly applicable and capable of adsorbing and clamping metal spacers of different diameters. In addition, by adjusting the radial and axial mounting positions of the suction cups 45 on the lower side plate 443, the heights of the three suction cups 45 can also be adjusted, so that metal spacers of different heights can be adsorbed.

[0049] A machine vision device (not shown in the figure) for identifying the metal spacer is provided on the clamping connecting plate 41. The machine vision device can identify the model of the metal spacer and transmit the model of the metal spacer to the PLC control system to automatically switch the detection program without manual operation on the PLC touch screen.

[0050] A pneumatic box 46 is provided on the surface of the loading workbench 50, and the vacuum suction cup 45 can be controlled by the pneumatic box so that the vacuum suction cup 45 can vacuum absorb the metal spacer.

[0051] like Figure 6-Figure 13As shown, the image detection system includes an image detection platform 25, on which an imager 23 and a movable platform 24 are provided. The centering clamping mechanism is installed on the movable platform 24, and the imager 23 is located above the support platform and directly faces the support platform.

[0052] The imager 23 is a common imager in the technical field, and is used to detect the outer diameter and inner diameter of the metal spacer.

[0053] The movable platform 24 can be slidably mounted on the image detection platform 25 in a manner commonly used in the technical field and is not specifically limited herein.

[0054] The centering clamping mechanism is arranged on a movable platform 24, and the movable platform 24 is used to drive the centering clamping mechanism to move toward the feeding system, so that the centering clamping mechanism can move toward the feeding system, thereby facilitating the transfer of the metal spacer from the feeding system to the centering clamping mechanism.

[0055] The centering clamping mechanism includes a mounting plate 10, on which a support platform is provided, the support platform includes a plurality of support bars 21 that are spaced apart and symmetrically arranged, and the metal spacer is placed on the plurality of support bars 21; a clamping mechanism is arranged above the support platform and is used to clamp the metal spacer; the clamping mechanism includes two parallel clamping struts 31, and the two clamping struts 31 can move toward each other and / or away from each other; corresponding sides of the two clamping struts 31 are respectively provided with clamping strips 32, and the clamping sides of the clamping strips 32 include two clamping planes 33 with obtuse angles.

[0056] The support platform includes a plurality of support bars 21 that are spaced apart and symmetrically arranged. The metal spacer is placed on the plurality of support bars 21, which can provide uniform support for the metal spacer so that the metal spacer can be placed stably on the support platform, so that the clamping mechanism can effectively and accurately center and clamp the metal spacer.

[0057] The clamping mechanism can achieve stable and effective automatic centering clamping for the metal spacer, so that the position of the metal spacer is centered, and the metal spacer can be located at the center of the support table, so as to facilitate more accurate detection of the metal spacer and improve detection accuracy.

[0058] An avoidance groove 34 is provided on the clamping side of the clamping strip 32. The avoidance groove 34 is clearance-matched with the support strip 21 to play an avoidance role, which can effectively prevent the support strip 21 from interfering with the movement of the clamping support strip 31, thereby ensuring that the clamping support strip 31 can move stably and effectively, thereby effectively centering and clamping the metal spacer.

[0059] In this embodiment, there are four support bars 21, which are dispersedly arranged to form a cross shape, and the opposite ends of the four support bars 21 are not connected. The metal spacer is placed on the four support bars 21, and the four support bars 21 can provide uniform support force to the metal spacer, play a uniform supporting role on the metal spacer, and ensure that the metal spacer is stably placed on the support table, so that the clamping mechanism can effectively and accurately clamp the metal spacer in the center.

[0060] In other preferred embodiments, the number of support bars 21 can also be three, and the three support bars 21 are dispersedly arranged, and the angle between two adjacent support bars 21 is 120°, and the opposite ends of the three support bars 21 are not in contact with each other, and no specific restrictions are made here. The metal spacer is placed on the three support bars 21, and the three support bars 21 can provide uniform support force to the metal spacer, play a uniform supporting role on the metal spacer, and ensure that the metal spacer is stably placed on the support table, so that the clamping mechanism can effectively and accurately clamp the metal spacer in the center.

[0061] The mounting plate 10 is provided with a support groove 11, and four mounting grooves 12 are symmetrically provided on the inner wall of the support groove 11, and the mounting ends 211 of the four support bars 21 are respectively installed in the four mounting grooves 12. The mounting ends 211 of the support bars 21 can be fixed in the mounting groove 12 by bolts, or by other methods commonly used in the art, which are not specifically limited here.

[0062] The relative ends 212 of the four support bars 21 are not connected to each other, and the four support bars 21 are arranged at intervals, so that there is no interaction force between the four support bars 21, so that the four support bars 21 are only subjected to the pressure of the metal spacer. The four support bars 21 are evenly stressed, avoiding bending and deformation of the support bars 21, thereby ensuring that the four support bars 21 are located on the same plane, and further allowing the metal spacer to maintain balance, so as to facilitate more accurate detection of the metal spacer and improve detection accuracy.

[0063] An illumination area 19 is provided in the support groove 11, and the illumination area 19 is located in the area surrounded by the opposite ends 212 of the four support bars 21. The metal spacer is placed on the four support bars 21, and after the metal spacer is centered and clamped by the clamping mechanism, the center of the metal spacer can correspond to the illumination area 19; the illumination area 19 can illuminate the metal spacer evenly, so as to facilitate more accurate detection of the metal spacer and improve detection accuracy.

[0064] Reinforcement ribs 22 are provided on both sides of the support bar 21. The reinforcement ribs 22 extend from the opposite end 212 of the support bar 21 toward the mounting end 211, and the width gradually increases. The reinforcement ribs 22 can strengthen the support bar 21, increase the strength of the support bar 21, and prevent the support bar 21 from bending and deformation, thereby ensuring that the four support bars 21 are located on the same plane, and then the metal spacers can maintain balance, so as to facilitate more accurate detection of the metal spacers and improve detection accuracy. In addition, the reinforcement ribs 22 extend from the opposite end 212 of the support bar 21 toward the mounting end 211, and the width gradually increases, which can ensure that the edge of the metal spacer with a smaller diameter can also be illuminated by the light of the lighting area 19, so as to meet the detection of metal spacers with different diameters.

[0065] The clamping strip 32 directly contacts the metal spacer and clamps the metal spacer. The material of the clamping strip 32 can be POM material, which can protect the metal spacer and prevent the metal spacer from being worn.

[0066] The clamping side of the clamping strip 32 includes two clamping planes 33 with an obtuse angle α, which can increase the clamping angle of the clamping strip 32 and effectively center and clamp the metal spacer.

[0067] The two clamping planes 33 are symmetrically arranged, and the two clamping planes 33 are planes. The metal spacer is clamped by clamping strips 32 on both sides thereof, and specifically, the two clamping planes 33 on the clamping strips 32 clamp the metal spacer; the two clamping planes 33 are planes, which can automatically and effectively center the metal spacer, so that the metal spacer can be centrally arranged, thereby improving the detection accuracy and detection efficiency of the metal spacer.

[0068] One side of the clamping stay 31 is connected with an elastic connector, the elastic connector is connected with a clamping bar connecting plate 35 , and the clamping bar 32 is connected to the clamping bar connecting plate 35 .

[0069] In this embodiment, there are two elastic connectors, which are symmetrically arranged on the clamping stay 31 .

[0070] The clamping stay 31 and the clamping strip 32 can be evenly stressed, ensuring that the clamping strip 32 can move smoothly and within limits.

[0071] The elastic connecting member includes a linear bearing 351 arranged on the clamping support bar 31, and a slidable guide shaft 352 is matched on the linear bearing 351, and the sliding direction of the guide shaft 352 is consistent with the moving direction of the clamping bar 32; a spring 353 is sleeved on the guide shaft 352, the clamping bar connecting plate 35 is fixed on the end of the guide shaft 352, and the clamping bar 32 is fixedly connected to the clamping bar connecting plate 35.

[0072] When the clamp 32 clamps the metal spacer, the clamp 32 will be squeezed by the metal spacer and move; when the clamp 32 moves, it will drive the guide shaft 352 to move, which can guide the movement of the clamp 32, so that the clamp 32 can move smoothly and effectively, ensuring that the clamp 32 has an effective centering and clamping effect on the metal spacer.

[0073] The linear bearing 351 can realize smooth and effective sliding of the guide shaft 352, thereby realizing smooth and effective movement of the clamping strip 32.

[0074] The spring 353 can buffer the clamping strip 32, thereby providing a buffering protection for the metal spacer to prevent the metal spacer from breaking. In addition, the spring 353 can clamp the metal spacer through its elastic resistance to the clamping strip 32, so that the clamping strip 32 can effectively center and clamp the metal spacer.

[0075] The clamping mechanism also includes a screw assembly for driving the two clamping stays 31 to move horizontally, and a slide rail 13 for guiding the movement of the two clamping stays 31; the screw 14 and the slide rail 13 of the screw assembly are parallel to the movement direction of the clamping stays 31.

[0076] One end of the clamping stay 31 is connected to the lead screw 14. Specifically, the lead screw 14 is provided with a lead screw nut 15, and one end of the clamping stay 31 is fixedly connected to the lead screw nut 15. By rotating the lead screw 14, the lead screw nut 15 and the clamping stay 31 can be driven to move along the lead screw 31.

[0077] The other end of the clamping stay 31 is slidably matched with the slide rail 13. Specifically, the bottom of the other end of the clamping stay 31 slides along the slide rail 13, thereby guiding the movement of the clamping stay 31, so that the clamping stay 31 can move smoothly and effectively.

[0078] The mounting plate 10 is provided with a slide rail groove 16 , and the slide rail 13 is fixedly installed in the slide rail groove 16 .

[0079] The mounting plate 10 is provided with an optical fiber sensor 17, which is used to detect the clamping stay 31. When the clamping stay 31 moves to the set position in the back direction, the optical fiber sensor 17 detects the clamping stay 31, and at this time, the optical fiber sensor 17 sends a signal to the PLC control system, and the PLC control system controls the motor of the lead screw assembly to stop moving, thereby stopping the clamping stay 31 from moving.

[0080] An outer shield 18 is provided on the mounting plate 10, and the outer shield 18 can prevent fingers from being pinched and dust from being cut, and can protect the operator and the metal spacer, thereby preventing the metal spacer from being damaged and contaminated.

[0081] The metal spacer is moved and placed on the support platform by the flexible clamping mechanism, and the two clamping stays 31 are driven to move toward each other (the two clamping stays 31 are close to each other) by the screw assembly, so that the clamping bars 32 on the two clamping stays 31 can clamp the two sides of the metal spacer in the center, so that the metal spacer can be located at the center of the support platform, and then the outer diameter and inner diameter of the metal spacer are detected by the imager 23. After the detection is completed, the two clamping stays 31 are driven to move back to each other (the two clamping stays 31 are away from each other) by the screw assembly to release the clamping of the metal spacer.

[0082] The mounting plate 10 is provided with an optical fiber sensor 17, which is used to detect the clamping stay 31. When the clamping stay 31 moves to the set position in the back direction, the optical fiber sensor 17 detects the clamping stay 31, and at this time, the optical fiber sensor 17 sends a signal to the PLC control system, and the PLC control system controls the motor of the lead screw assembly to stop moving, thereby stopping the clamping stay 31 from moving.

[0083] like Fig.14 As shown, the detection system of the metal spacer for the elastic bearing of the utility model also includes a blue light detection system. After the image detection system completes the detection of the metal spacer, the loading robot 40 of the loading system drives the flexible clamping mechanism to move to the top of the metal spacer to adsorb and clamp the metal spacer. Then the loading robot 40 drives the flexible clamping mechanism and the metal spacer to move to the blue light detection system. The blue light detection system detects the thickness, inner ball radius and weight of the metal spacer.

[0084] The blue light detection system includes a blue light detection table 60, on which a blue light robot 61 is disposed. The mechanical arm of the blue light robot 61 is connected to a blue light scanning system 62, which can scan and detect the thickness and inner sphere radius of the metal spacer.

[0085] A balance 63 is provided on the table of the blue light detection table 60, and the balance 63 can detect the weight of the metal spacer.

[0086] like Fig.15 As shown, the detection system of the metal spacer for elastic bearing of the utility model also includes a feeding system, and the feeding robot 40 can place the metal spacer after the detection on the feeding system. The feeding system includes a feeding table 70, and a rubber pad 71 is provided on the table of the feeding table 70, and a feeding shaft 72 is vertically provided on the rubber pad 71. The metal spacer 72 passes through the feeding shaft 72 and is placed on the rubber pad 71. The rubber pad 71 can protect the metal spacer, and the feeding shaft 72 can limit the metal spacer to prevent the metal spacer from being separated from the rubber pad 71.

Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents.
