[0049] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0051] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "above," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as "below" or "below" of the other element or feature will be oriented "above" the other element or feature. Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0052] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0053] Reference Figure 13 As shown, the valve disc shaft 1 includes a first shaft segment 2 and a second shaft segment 3, the second shaft segment 3 having an elongated hole 4 and at least two screw holes 5.

[0054] Reference Figures 1-2 As shown, the present invention provides a technical solution: a valve disc shaft detection device, including a workbench 10 and a length measuring mechanism 20; the length measuring mechanism 20 is disposed on the workbench 10, and the length measuring mechanism 20 includes a first support component 21, a moving component 22 and a length measuring component. The first support component 21 includes a guide support 211, and a first abutment 2111 is provided on one side wall of the guide support 211. The moving component 22 is disposed on the bottom wall of the guide support 211, and a second abutment 221 is provided at the output end of the moving component 22. The second abutment 221 is arranged opposite to the first abutment 2111, and the length measuring component is arranged opposite to the end of the second abutment 221 that is away from the first abutment 2111.

[0055] For example, both the first abutment 2111 and the second abutment 221 can be rod-shaped structures, etc. The length measuring component can be a laser displacement sensor, etc.

[0056] In this embodiment, during measurement, the moving component 22 drives the second abutment 221 to push the valve shaft 1 tightly against the first abutment 2111, so that the first abutment 2111 and the second abutment 221 clamp both ends of the valve shaft 1, eliminating axial movement. During the movement of the second abutment 221, the length measuring component directly measures the displacement of the second abutment 221, which is equivalent to the shaft length. This not only improves measurement efficiency without manual intervention but also avoids measurement reference drift, ensuring the accuracy of length measurement.

[0057] Reference Figure 2 As shown, in some embodiments, the first support component 21 includes two guide members 212 arranged in parallel. Each guide member 212 includes a guide shaft 2121 and at least two rollers 2122. The two ends of the guide shaft 2121 are connected to the two side walls of the guide support 211 in a corresponding manner, and the at least two rollers 2122 are sleeved on the guide shaft 2121.

[0058] In this embodiment, the guide shaft 2121 is fixed at both ends to the sidewall of the guide support 211, forming a stable support frame. When the valve disc shaft 1 is placed on the two rollers 2122, the two guide shafts 2121 support the valve disc shaft 1. When the valve disc shaft 1 is pushed by the second abutment member 221, the rollers 2122 reduce the frictional resistance of the shaft movement and reduce the risk of scratches on the shaft surface.

[0059] Reference Figure 2 As shown, in some embodiments, the moving component 22 includes a top material seat 222, a first moving member 223, a first connecting plate 224 and a second moving member 225 arranged sequentially toward the bottom wall of the guide support 211. The top material seat 222 serves as the output end of the moving component 22, and the length measuring member is disposed on the first connecting plate 224.

[0060] For example, the first moving part 223 and the second moving part 225 can be a slide cylinder, etc.

[0061] In this embodiment, the first moving member 223 and the second moving member 225 can achieve layered driving. The first moving member 223 can drive the top material seat 222 to move towards the first abutment member 2111, so that the second abutment member 221 cooperates with the first abutment member 2111 to clamp the valve shaft 1. When the length of the valve shaft 1 is short, the second moving member 225 can drive the first connecting plate 224 to move, thereby compensating for the stroke of the first moving member 223.

[0062] Reference Figure 1 and Figure 3As shown, in some embodiments, the valve plate shaft detection device includes a vision inspection device 30, which is disposed on the worktable 10. The vision inspection device 30 is arranged opposite to the length measuring mechanism 20. The vision inspection device 30 includes a support mechanism 31 and a first vision inspection mechanism 32. The support mechanism 31 includes a second support component 311, the structure of which is the same as that of the first support component 21. The first vision inspection mechanism 32 includes a first fixed base 321 and a first camera 322, which is mounted on the first fixed base 321. The lens of the first camera 322 faces the two guide shafts 2121 in the second support component 311.

[0063] In this embodiment, when the valve plate shaft 1 is placed on the second support assembly 311, the lens of the first camera 322 faces the area of ​​the guide shaft 2121, capturing a panoramic image of the surface of the first shaft segment 2, thereby measuring the characteristic parameters of the first shaft segment 2. The characteristic parameters of the first shaft segment 2 may include diameter, length, and flatness, etc.

[0064] Reference Figures 3 to 4 As shown, in some embodiments, a first light source 3111 is provided on the bottom wall of the guide support 211 in the second support assembly 311, and the light-emitting end of the first light source 3111 faces the first camera 322.

[0065] For example, the first light source 3111 can be a rectangular LED light.

[0066] In this embodiment, the first light source 3111 provides supplementary light from the bottom wall of the guide support 211, and the light is evenly distributed to eliminate backlight shadows and enhance the imaging contrast of surface scratches and pits.

[0067] Reference Figures 3 to 4 As shown, in some embodiments, the support mechanism 31 includes a top material assembly 312, which includes a first top material drive 3121 and a top material head 3122. The first top material drive 3121 is mounted on a side wall of the guide support 211 in the second support assembly 311, and the top material head 3122 is located at the output end of the first top material drive 3121.

[0068] For example, the first ejector drive 3121 can be a cylinder or a hydraulic cylinder, etc.

[0069] In this embodiment, when the valve shaft 1 is placed on the second support assembly 311, the first ejector drive 3121 drives the ejector head 3122 to move toward the valve shaft 1, which can press against the valve shaft 1 and prevent the valve shaft 1 from being displaced.

[0070] Reference Figures 3 to 4As shown, in some embodiments, the first visual inspection mechanism 32 includes a second camera 323, which is mounted on the first fixed base 321, and the lens of the second camera 323 faces the two guide shafts 2121 in the second support assembly 311.

[0071] In this embodiment, the second camera 323 can detect whether there is a thread in the screw hole 5, thereby ensuring the yield rate.

[0072] Reference Figures 3 to 4 As shown, in some embodiments, the support mechanism 31 includes a position detection component 313, a transmission component 314, and a drive motor 315. The position detection component 313 includes a fixed frame 3131 and a through-beam photoelectric sensor 3132. Two fixed frames 3131 are configured, and both fixed frames 3131 are disposed on the bottom wall of the guide support 211 in the second support component 311. The two fixed frames 3131 are arranged symmetrically about the defined axis L. The photoelectric emitter and photoelectric receiver of the through-beam photoelectric sensor 3132 are disposed on the two fixed frames 3131 respectively. The transmission component 314 and the drive motor 315 are disposed on the other side wall of the guide support 211 in the second support component 311, away from the position detection component 313. Two through holes are opened on the other side wall of the guide support 211 in the second support component 311. Two guide shafts 2121 in the second support component 311 pass through the through holes respectively and are connected to the transmission component 314. The output end of the drive motor 315 is connected to the transmission component 314.

[0073] For example, the transmission assembly 314 may include a synchronous belt transmission assembly 314 or a chain transmission assembly 314, etc.

[0074] In this embodiment, when the valve shaft 1 is placed on the second support assembly 311, the through-beam photoelectric sensor 3132 can detect whether the screw hole 5 is facing the first camera 322. If the screw hole 5 is not facing the first camera 322, the drive motor 315 drives the guide shaft 2121 to rotate through the transmission assembly 314, causing the valve shaft 1 to rotate circumferentially, so that the screw hole 5 is facing the first camera 322.

[0075] It should be noted that when detecting the position of the screw hole 5 on the valve shaft 1, the photoelectric transmitter emits an optical fiber towards the photoelectric receiver. If the light from the photoelectric transmitter passes through the elongated hole 4 and is received by the photoelectric receiver, it can be determined that the screw hole 5 is aligned with the first camera 322. If the light from the photoelectric transmitter does not pass through the elongated hole 4 and is not received by the photoelectric receiver, it can be determined that the screw hole 5 is not aligned with the first camera 322. By adjusting the position of the screw hole 5, the screw hole 5 on the valve shaft 1 can be aligned with the first camera 322, making it easier for the second camera 323 to capture the thread of the screw hole 5.

[0076] Reference Figure 3 and Figures 5 to 6 As shown, in some embodiments, the support mechanism 31 includes a polarizing component 316, which is arranged opposite to the second support component 311. The polarizing component 316 includes a third moving member 3161, a bracket 3162, a fourth moving member 3163, a second connecting plate 3164, and a plug gauge 3165. The bracket 3162 is located at the output end of the third moving member 3161, the fourth moving member 3163 is located on the bracket 3162, one end of the second connecting plate 3164 is connected to the output end of the fourth moving member 3163, and the plug gauge 3165 is located at the other end of the second connecting plate 3164.

[0077] For example, the third moving part 3161 and the fourth moving part 3163 may be a slide cylinder, etc.

[0078] In this embodiment, the fourth moving member 3163 drives the plug gauge 3165 to insert into the screw hole 5, and the skewness of the plug gauge 3165 can reflect the coaxiality error. The third moving member 3161 drives the plug gauge 3165 to move, so that the plug gauge 3165 can detect multiple screw holes 5.

[0079] Reference Figures 5 to 6 As shown, in some embodiments, the polarizing assembly 316 includes a refractor 3166, which is disposed at the end of the plug gauge 3165 away from the second connecting plate 3164, and the light-incident surface of the refractor 3166 faces the light-out end of the photoelectric emitter.

[0080] In this embodiment, when the valve shaft 1 is placed on the second support assembly 311, if the valve shaft 1 is slightly deflected and the elongated hole 4 is not directly facing the emitting end of the photoelectric emitter, the light from the photoelectric emitter can still pass through the elongated hole 4 due to its height. Therefore, when detecting the position of the screw hole 5 of the valve shaft 1, the fourth moving member 3163 drives the plug gauge 3165 to insert into the elongated hole 4, so that the refracting mirror 3166 is directly facing the emitting end of the photoelectric emitter. When the light from the photoelectric emitter is emitted towards the elongated hole 4, the refracting mirror 3166 refracts the light at a certain angle. If the photoelectric receiver can still receive the light, it can be determined that there is no slight deflection and the screw hole 5 is directly facing the first camera 322; if the photoelectric receiver cannot receive the light, it can be determined that there is a slight deflection and the screw hole 5 is not directly facing the first camera 322.

[0081] Reference Figure 3 As shown, in some embodiments, the first visual inspection mechanism 32 includes a second light source 324, which is mounted on a first fixed base 321, and the light-emitting end of the second light source 324 faces the two guide shafts 2121 in the second support assembly 311.

[0082] For example, the second light source 324 can be a strip LED or the like.

[0083] In this embodiment, the second light source 324 provides lateral supplementary lighting to highlight the texture features of the screw hole 5 and enhance the imaging salience of the thread.

[0084] Reference Figure 1 and Figures 7 to 9 As shown, in some embodiments, the valve plate shaft detection device includes a first transfer assembly 40 and a feeding assembly 50. The first transfer assembly 40 and the feeding assembly 50 are disposed on the worktable 10. The first transfer assembly 40 is arranged opposite to the vision inspection device 30. The feeding assembly 50 includes a second fixed base 51, a material box 52, a guide plate 53, a pusher plate 54, and a second top-loading drive component 55. The second fixed base 51 is disposed on the worktable 10, and the material box 52 is disposed on the back of the upright plate 511 of the second fixed base 51. On the side away from the length measuring mechanism 20, the guide plate 53 is located on the side of the upright plate 511 of the second fixed base 51 close to the length measuring mechanism 20. The push plate 54 is located between the upright plate 511 of the second fixed base 51 and the material box 52. The second top material driving member 55 is installed on the bottom plate of the second fixed base 51. The output end of the second top material driving member 55 is connected to the push plate 54. The side of the push plate 54 away from the second top material driving member 55 is configured to be inclined toward the upright plate 511 of the second fixed base 51.

[0085] For example, the first transfer component 40 may include a PPU robot 41, a mounting plate 42, and grippers 43, etc. The mounting plate 42 is located at the output end of the PPU robot 41, and the grippers 43 are mounted on the mounting plate 42.

[0086] In this embodiment, when the side of the pusher plate 54 facing away from the second top-loading drive member 55 is flush with the bottom wall of the material box 52, the valve shaft 1 will roll onto the pusher plate 54. Simultaneously, the second top-loading drive member 55 drives the pusher plate 54 to rise to the guide plate 53, and the valve shaft 1 rolls onto the guide plate 53 due to the inclined surface of the pusher plate 54. At this time, the first transfer assembly 40 can clamp the valve shaft 1 and transfer it to the first support assembly 21. Furthermore, when the length measuring mechanism 20 completes the length measurement of the valve shaft 1, the first transfer assembly 40 can clamp the valve shaft 1 and transfer it to the second support assembly 311, thereby achieving automated operation.

[0087] Reference Figure 1 As shown, in some embodiments, the valve plate shaft detection device includes a second vision detection mechanism 60, which is disposed on the worktable 10. The feeding assembly 50 includes a first conveyor 56, the transmission start end of the first conveyor 56 corresponds to the guide plate 53, and the second vision detection mechanism 60 is located between the first conveyor 56 and the length measuring mechanism 20. The second vision detection mechanism 60 includes a vision measuring device 61.

[0088] For example, the guide plate 53 is configured to be inclined toward the first conveyor 56. The vision measuring device 61 can be an in-line projected image measuring instrument, such as the TM-X5040.

[0089] In this embodiment, when the valve plate shaft 1 rolls onto the guide plate 53, the first conveyor 56 receives the valve plate shaft 1. The first transfer assembly 40 can transfer the valve plate shaft 1 to the vision measuring device 61, and the vision measuring device 61 measures the characteristic parameters of the second shaft segment 3. The characteristic parameters of the second shaft segment 3 may include diameter, length, and the diameter of the screw hole 5, etc.

[0094] In this embodiment, after the viewing angle measuring device measures the valve shaft 1, the second transfer assembly 62 moves the valve shaft 1 to the feeding seat 71, so that the feeding seat 71 holds the valve shaft 1 to be inspected. At the same time, the pressing component 72 presses the valve shaft 1 to prevent the valve shaft 1 from rolling off.

[0095] Reference Figure 1 and Figure 11 As shown, in some embodiments, the valve plate shaft detection device includes a discharge assembly 80, which is disposed on the worktable 10.

[0096] For example, the storage box 82 is located on one side of the second conveyor 81, and the second conveyor 81 is provided with a guide plate 811 corresponding to the storage box 82.

[0097] In this embodiment, after the visual inspection device 30 completes the inspection of the valve plate shaft 1, the first transfer component 40 transfers the valve plate shaft 1 that has passed the final inspection to the second conveyor 81, so that the second conveyor 81 transports the valve plate shaft 1 that has passed the final inspection to the first storage box 82 for automatic stacking.
