Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] See also Figure 1-Figure 8 The present invention provides an armature testing machine 10, which includes a workbench 100, a transmission mechanism 200, a marking mechanism 300, a copper sand detection mechanism 400 and an electrical performance detection mechanism 500. The transmission mechanism 200, the marking mechanism 300, the copper sand detection mechanism 400 and the electrical performance detection mechanism 500 are all arranged on the workbench 100.

[0037] The transmission mechanism 200 is sequentially provided with a first operating area 210, a second operating area 220 and a third operating area 230 along the transmission direction. The transmission mechanism 200 can be used to carry the armature and drive the armature to move along the first operating area 210, the second operating area 220 and the third operating area 230 in sequence.

[0038] In an optional embodiment, the transmission mechanism 200 may be a transmission trough, or a transmission structure of a transmission belt and a carrier plate, or a transmission device of a transmission belt and a synchronous material moving mechanism, which is not limited here.

[0039] In an optional embodiment, the transmission mechanism 200 may include two transmission belts arranged in parallel, and each transmission belt can independently transmit the armature.

[0040] In an optional embodiment, the transmission mechanism 200 further includes a material detection component for detecting whether there is an armature in the corresponding operating area or workstation.

[0041] like Figure 2As shown, the marking mechanism 300 includes a plurality of marking pens 310, which can be used to mark a plurality of armatures on the first operating area 210 so that each armature has a different mark. In an optional embodiment, each marking pen 310 can have a different color, so that the corresponding armature can be marked with a different color mark.

[0042] In a specific scenario, the first operating area 210 includes four placement stations for placing armatures. Each placement station can place armatures produced by different production lines. After marking the armatures produced by these different production lines with a marking pen 310, in subsequent inspections, it can be effectively determined which production line each armature is produced by.

[0043] like Figure 1 , Figure 4 as well as Figure 5 As shown, the copper sand detection mechanism 400 includes a first grabbing mechanism 410 and a copper sand detection assembly 420. The first grabbing mechanism 410 grabs the armature and places it to the copper sand detection area of ​​the copper sand detection assembly 410. The copper sand detection assembly 420 is used to detect whether there is copper sand in the armature in the copper sand detection area. The first grabbing mechanism 410 is used to further place the armature with copper sand in the first placement area.

[0044] In a specific scenario, after the armature is processed, the commutator of the armature will include multiple copper sheets arranged at intervals. If it is not cleaned thoroughly, copper sand will be left in the gaps between adjacent copper sheets, which will cause a short circuit during subsequent operation of the armature. By detecting the armature and the commutator in the armature, the armature with copper sand can be detected and deemed unqualified, and the unqualified armature can be grabbed by the first grabbing mechanism 410 and placed in the first placement area 611.

[0045] like Figure 1 , Figure 6 as well as Figure 7 As shown, the electrical performance detection mechanism 500 includes a second grasping mechanism 510 and an electrical performance detection component 520. The second grasping mechanism 510 is used to grasp the armature in the third operating area 230 and move it to the electrical performance detection area of ​​the electrical performance detection component 520. The electrical performance detection component 520 is used to detect whether the electrical performance information of the armature in the electrical performance detection area is qualified. The second grasping mechanism 510 also grasps the armature with unqualified electrical performance and places it in the second placement area.

[0046] In a specific scenario, the armature after the copper sand test is qualified will be further transferred to the third operation area 230, and then the electrical performance testing mechanism 500 will test the electrical performance of the armature, such as resistance, and determine whether its electrical performance is qualified. If it is unqualified, the unqualified armature will be grabbed and placed in the second placement area 621.

[0047] In the above embodiment, an armature detection machine 10 is provided, wherein the armature can be carried and transmitted in different operation areas by the transmission mechanism 200, and different armatures can be marked differently by the marking mechanism 300 so that the qualified rates of armatures produced by different production lines can be quickly determined in the subsequent qualified rate survey. Subsequently, the armature can be subjected to copper sand detection by the copper sand detection mechanism 400, and the armature that fails the copper sand detection can be grabbed and placed in the first placement area 611, and then the armature can be subjected to electrical performance detection by the electrical performance detection mechanism 500, and the armature that fails the electrical performance can be grabbed and placed in the first placement area 621. Thus, unqualified products can be quickly screened out to ensure the success rate of the final finished product. Moreover, by performing different tests on the armature and placing it in different placement areas, the reasons and quantity of unqualified armatures can be quickly determined, so as to facilitate the subsequent improvement of the production line.

[0048] like Figure 1 and Figure 2 As shown, the armature inspection machine 10 further includes a first placement plate 610 and a second placement plate 620 disposed on the workbench 200, wherein the first placement area 611 is located on the first placement plate 610, and the second placement area 621 is located on the second placement plate 620. Moreover, both the first placement plate 610 and the second placement plate 620 can be drawer-type designs, so that the first placement plate 610 or the second placement plate 620 with unqualified armatures can be quickly taken out, thereby facilitating manual inspection of the armatures.

[0049] like Figure 3 As shown, the marking mechanism 300 further includes a support assembly 320 disposed on the workbench 100 and a first rotating assembly 330 disposed on the support assembly 310. The first rotating assembly 330 includes a first rotating shaft 331 parallel to the transmission direction of the transmission mechanism 200, and a plurality of marking pens 310 are sequentially arranged at intervals along the length direction of the first rotating shaft 331.

[0050] In an optional embodiment, the length directions of the plurality of marking pens 310 may be perpendicular to the first rotation axis 331, so that when the first rotation axis 331 rotates, the rotation path of the first marking pen 310 may reach the highest.

[0051] In an optional embodiment, a pen tip is provided at one end of the marking pen 310 away from the first rotating shaft 331, and the rotation path of the marking pen 310 around the first rotating shaft 331 corresponds to the armature, so when the first rotating assembly 330 drives the plurality of marking pens 331 to rotate, the plurality of marking pens 331 can mark the armature located on the rotation path of the marking pens 331 in the first operating area 210. That is, the pen tip of the marking pen 331 can scratch the side wall of the armature to leave a mark on the armature.

[0052] like Figure 2 As shown, the support assembly 320 includes two support columns 321, a support plate 322, a first lifting assembly 323 and a connecting plate 24. The two support columns 321 are arranged on the workbench 100 at intervals and are both located on the same side of the transmission mechanism 200, and the distance direction of the two support columns 321 is parallel to the transmission direction of the transmission mechanism 200. The support plate 322 is mounted on the two support columns 321, and the first lifting assembly 323 is arranged on the support plate 322, and the first lifting assembly 323 includes a first lifting output end penetrating the support plate 322; the connecting plate 324 is connected to the first lifting output end and is located between the support plate 322 and the workbench 100; the rotating assembly 330 is arranged on the connecting plate 324, and the first lifting assembly 323 can integrally drive the connecting plate 324, the rotating assembly 330 and the plurality of marking pens 310 to approach or move away from the workbench 200 through the first lifting output end.

[0053] Optionally, by setting up a first lifting assembly 323, you can drive the connecting plate 324, the rotating assembly 330 and multiple marking pens 310 to move closer to or away from the workbench 200, so that the rotation path of the marking pen 310 during rotation can be controlled, thereby facilitating better marking of the armature.

[0054] like Figure 4 As shown, the first gripping mechanism 410 includes a first translation component 411, a second lifting component 412, a second rotation component 413 and a first clamping member 414. The first translation component 414 is disposed on the workbench 200, and includes a first translation output end. The second lifting component 412 is disposed on the first translation output, and the second lifting component 412 includes a second lifting output end. The second rotation component 413 is disposed on the second lifting output end, and the second rotation component 413 includes a second rotation axis, and the axis of the second rotation axis is parallel to the axis of the armature. In the working state, the axis of the second rotation axis of the second rotation component 413 is in the same direction as the plumb line. The first clamping member 414 is arranged on the second rotating axis; the first translation component 411 is used to drive the second lifting component 412, the second rotating component 413 and the first clamping member 414 to move back and forth between the first placement plate 610 and the transmission mechanism 200 as a whole through the first translation output end; the second lifting component 412 is used to drive the second rotating component 413 and the first clamping member 414 as a whole to approach or move away from the transmission mechanism 200 from the top of the transmission mechanism 200, that is, the side of the transmission mechanism 200 away from the workbench; the first clamping member 414 is used to grab the armature.

[0055] Optionally, the copper sand detection component 420 includes a shooting component 421 and two fill lights 422 located between the first placement area 611 and the transmission mechanism 200, and the copper sand detection area is located between the two fill lights 422. The second rotating component 413 is used to drive the armature to rotate around the second rotation axis in the copper sand detection area, and the shooting component 421 is used to shoot the armature rotating in the copper sand detection area to obtain a spread image of the commutator in the armature and determine whether there is copper sand in the armature based on the spread image.

[0056] In a specific scenario, the bottom end of the armature includes a commutator, which is specifically composed of a plurality of copper sheets arranged around the armature axis and at intervals. The first clamping member 414 can clamp the top of the armature, and move it to the copper sand detection area under the cooperative drive of the first translation assembly 411 and the second lifting assembly 412, and make the commutator located in the shooting area of ​​the shooting assembly 421, and then the fill light 422 fills the commutator with light and the second rotating assembly 413 drives the armature to rotate, so that the shooting assembly 421 can shoot the commutator of the armature in all directions when shooting, and form a rectangular spread image. The spread image includes the image information of all the copper sheets in the commutator, and then the spread image is analyzed to determine whether there is copper sand between the gaps between the copper sheets.

[0057] In an optional embodiment, the second rotating assembly 413 drives the armature to rotate greater than or equal to 360 degrees. In an optional embodiment, the second rotating assembly 413 drives the armature to rotate 380°, 420°, or 450°, which is not specifically limited here.

[0058] After completing the inspection, if the armature includes copper sand, that is, the inspection fails, the first grasping mechanism 410 grasps the armature and moves toward the direction of the first placement plate 610, and places the armature on the first placement area 611 of the first placement plate 610; if the armature does not include copper sand, that is, the inspection passes, the first grasping mechanism 410 grasps the armature and moves toward the direction of the transmission mechanism 200, and places the armature back in the second operating area 220 of the transmission mechanism 200.

[0059] like Figure 6 As shown, the second grasping mechanism 510 includes a second translation component 511, a third lifting component 512 and a second clamping member 513, wherein the second translation component 511 is arranged on the workbench 200 and includes a second translation output end, the third lifting component 512 is arranged on the second translation output and includes a third lifting output end; the second clamping member 513 is arranged on the third lifting output end.

[0060] Among them, the second translation component 511 is used to drive the third lifting component 512 and the second clamping member 513 to move back and forth between the second placement plate 620 and the transmission mechanism 200 through the second translation output end as a whole, the third lifting component 512 is used to drive the second clamping member 513 to approach or move away from the transmission mechanism 200 from above the transmission mechanism 200, and the second clamping member 513 is used to grab the armature.

[0061] like Figure 6 and Figure 7 As shown, the electrical performance detection assembly 520 includes a test seat 521 located between the second placement plate 620 and the transmission mechanism 200 and an angle detection member 522 disposed on the test seat 521 .

[0062] In other embodiments, the angle detection member 522 may not be disposed on the test seat 521 , which is not limited here.

[0063] Among them, after the second grasping mechanism 510 grasps the armature and places it in the electrical performance detection area on the test socket 521, the test socket 521 is used to perform electrical performance detection on the armature in the electrical performance detection area through a probe to obtain electrical performance detection information, and the angle detection component 522 is used to detect the placement angle of the armature and compensate the electrical performance detection information based on the placement angle. The electrical performance detection component 520 further determines whether the electrical performance of the armature is qualified based on the compensated electrical performance detection information.

[0064] In a specific scenario, when the armature is placed on the test seat 521, multiple probes of the test seat 521 can abut against the armature and perform electrical performance tests on the armature. Since the test will be affected by the relative angle between the armature and the probe, an angle detection member 522 is further provided. The angle detection member 522 can specifically be a distance sensor. The armature is provided with multiple slots along the circumference. The detection light of the angle detection member 522 is incident on the outer surface of the armature and the distance information obtained in the slots of the armature is different, so that the angle of the armature can be detected. Subsequently, the electrical performance information directly detected by the test seat 521 is compensated using the placement angle, so that the actual electrical performance test information of the armature can be effectively and accurately obtained, and whether the electrical performance of the armature is qualified can be determined based on the compensated electrical performance test information.

[0065] Similarly, after completing the inspection, if the electrical performance information of the armature is unqualified, the second grasping mechanism 510 grasps the armature and moves toward the direction of the second placement plate 620, and places the armature on the first placement area 621 of the second placement plate 620; if the electrical performance information of the armature is qualified, the second grasping mechanism 510 grasps the armature and moves toward the direction of the transmission mechanism 200, and places the armature back into the three operating areas 230 of the transmission mechanism 200.

[0066] In an optional embodiment, there are two copper sand detection mechanisms 400 arranged adjacent to each other, and there may be two corresponding first placement plates 610. The two copper sand detection mechanisms 400 can independently perform copper sand detection on the armature on the transmission mechanism 200, thereby effectively speeding up the detection efficiency.

[0067] Similarly, there may be two adjacent electrical performance detection mechanisms 500, and there may be two corresponding second placement plates 620. The two electrical performance detection mechanisms 500 may independently perform electrical performance detection on the armature on the transmission mechanism 200, thereby effectively improving the detection efficiency.

[0068] In the above embodiment, the first translation assembly 410 and the second translation assembly 510 can both be screw assemblies. The first lifting assembly 323, the second lifting assembly 412 and the third lifting assembly 512 can be lifting cylinders or lifting motors, and the first clamping member 414 and the second clamping member 513 can be clamping cylinders, etc., which are not specifically limited here. Optionally, the second lifting assembly 412 and the second lifting assembly 512 can also be translation assemblies with higher precision such as screw assemblies.

[0069] like Figure 2 and Figure 8 As shown, the armature testing machine 10 further includes a flip assembly 700, which is used to flip the qualified armature that has passed the copper sand testing mechanism 400 and the electrical performance testing mechanism 500. The flip assembly 700 includes a flip cylinder 710 and a clamping member 720 disposed on the flip cylinder 710. The clamping member 720 is used to clamp the armature, and the flip cylinder 710 is used to drive the clamping member 720 and the armature to flip. So that the top and bottom ends of the armature are turned around. This facilitates the operation of the armature on the next production line.

[0070] The present invention further provides an armature detection method, which is applied to the armature detection machine 10 in any of the above embodiments, and the method comprises:

[0071] First, placing a plurality of armatures into a first operating area of ​​the transmission mechanism;

[0072] second, the marking mechanism uses the multiple marking pens to mark different armatures in the first operating area in different ways;

[0073] Third, the transmission mechanism drives the armature of the first operating area to the second operating area;

[0074] Fourth, the first grabbing mechanism grabs the armature in the second operating area and moves it to the copper sand detection area, and drives the armature to rotate;

[0075] Fifth, the copper sand detection component detects the armature rotating in the copper sand detection area to determine whether the armature has copper sand;

[0076] Sixth, the first grabbing mechanism grabs the armature with copper sand in the copper sand detection area and places it in the first placement area and / or grabs the armature without copper sand in the copper sand detection area and places it back to the second operation area;

[0077] Seventh, the transmission mechanism drives the armature without copper sand in the second operating area to the third operating area;

[0078] Eighth, the second grasping mechanism moves the armature in the third operating area to the electrical performance detection area;

[0079] Ninth, the electrical performance detection component detects the armature in the electrical performance detection area and determines whether the electrical performance information of the armature is qualified;

[0080] Tenth, the first grasping mechanism grasps the armature with unqualified electrical performance in the electrical performance detection area and places it in the first placement area and / or grasps the armature with qualified electrical performance in the electrical performance detection area and places it back to the third operation area.

[0081] In summary, an armature detection machine 10 is provided, wherein the armature can be carried and transmitted in different operation areas by the transmission mechanism 200, and different armatures can be marked differently by the marking mechanism 300 so that the qualified rates of armatures produced by different production lines can be quickly determined in the subsequent qualified rate survey. Subsequently, the armature can be subjected to copper sand detection by the copper sand detection mechanism 400, and the armature that fails the copper sand detection can be grabbed and placed in the first placement area 611, and then the armature can be subjected to electrical performance detection by the electrical performance detection mechanism 500, and the armature that fails the electrical performance can be grabbed and placed in the first placement area 621. Thus, unqualified products can be quickly screened out to ensure the success rate of the final finished product. Moreover, by performing different tests on the armature and placing it in different placement areas, the reasons and quantity of the unqualified armature can be quickly determined, so as to facilitate the subsequent improvement of the production line. Moreover, through automated detection, the efficiency of the overall detection can be greatly improved, thereby effectively reducing labor costs and improving the overall production efficiency.
