[0038] Furthermore, the oil injection equipment includes an oil injection protective cover used in conjunction with the OK track line and an oil injection nozzle arranged on the oil injection protective cover.

[0039] The beneficial technical effects of the present invention are:

[0040] 1. The stator loading, angle alignment, size measurement and other related data tests are completed through the fully automatic inspection line. Finally, the stator is subjected to load-bearing treatment, and the qualified stators are sprayed with oil, and the unqualified stators are unloaded through the NG track line. The entire process is completed independently by automated equipment, which not only improves the inspection efficiency but also ensures the accuracy compared with manual or semi-automatic inspection.

[0041] 2. The setting of the left chain plate line and the right chain plate line is used to match the client's double-row mold. By defining the transfer component, the stator on the left chain plate line is moved to the right chain plate line, which is convenient for equidistant conveying component loading.

[0042] Multiple transport clamping components are arrayed on the linear translation module. The linear translation module simultaneously drives multiple transport clamping components to complete the clamping and fixing of stators at different stations, and complete the transport, so that multiple different test stations can be tested simultaneously.

[0043] The angle alignment camera confirms whether the angle of the stator is correct. If the stator is not at the specified angle, the angle alignment camera gives data, and the rotary motor drives the electrons to rotate through the rotating platform to reach the specified position, thereby facilitating the handling of the stator.

[0044] The angle alignment camera confirms whether the front and back sides of the stator are correct. When the front and back sides of the stator are correct, the angle data of the stator is further confirmed to facilitate the angle adjustment of the stator.

[0045] When the front and back sides of the stator are wrong, the stator is lifted to a certain height through the clamping and flipping device, and the stator is flipped. The flipped stator is placed on the rotating platform through the clamping and flipping device, and the angle alignment camera confirms the angle data of the stator again to facilitate the angle adjustment of the stator.

[0046] The setting of the L-shaped stopper further ensures the stability of the stator during the turning process.

[0047] 3. The setting of the marking and scanning station not only records the relevant information of the stator, but also avoids dust splashing during the marking process.

[0048] 4. The inner diameter of the stator is detected by an inner diameter gauge. At the same time, the inner diameter gauge is elastically set to avoid rigid contact between the inner diameter gauge and the end of the stator when the inner diameter of the stator is small, so as to protect the stator.

[0049] Since the stator is composed of multiple layers of parts, pressure is applied to the upper end surface of the stator through a pressure plate so that the height sensor can measure the height of the stator to ensure test accuracy.

[0050] The pressure plate and the flatness detection sensor are used in conjunction with each other to be able to test the flatness of the stator end face.

[0051] The test bracket and the fixing seat are detachably arranged, and the setting of the guide rod, the arc bracket and the fixing seat facilitates the assembly and removal of the test component, so that the suitable test component can be replaced according to different workpieces.

[0052] The setting of the support rod facilitates the placement of the entire test assembly and avoids damage to components such as the inner diameter gauge.

[0053] The setting of the centering rod improves the pressing accuracy of the entire test assembly.

[0054] 5. The end face runout detection station is set up. The stator is fixed by a tensioning head, and then the hollow rotary servo drives the stator to rotate through the tensioning head. The end face runout of the stator is tested by the upper distance sensor and the lower distance sensor during the rotation of the stator. The structure is simple and easy to operate.

[0055] 6. A bar gauge is inserted into the stator to detect the passability of the wire slots inside the stator. One descent of the wire slot gauge assembly can detect all the wire slots inside the stator, which improves efficiency compared to manual detection. After one detection is completed, the stator rotates one wire slot angle and is detected again through the wire slot gauge assembly to improve the detection accuracy.

[0056] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0095] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0096] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0097] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships described in the embodiments and shown in the accompanying drawings, or are directions or positional relationships in which the inventive product is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0098] like Figure 1-Figure 27 As shown, the present invention specifically relates to a motor stator test line, which takes the direction of stator feeding as a reference and sequentially comprises: a loading station 100, an angle alignment station 200, a marking and scanning station 300, an appearance dimension detection station 400, an end face runout detection station 500, a wire slot gauge detection station 600, an air shower cleaning station 700, a sheet gap detection station 800, an end face detection station 900 and a product unloading station 1000.

[0099] Among them, the loading station 100 includes a loading chain plate line 110 and an equidistant conveying component 120. The equidistant conveying component 120 can transport the stator located on the loading chain plate line 110 to the loading station 100, the angle alignment station 200, the marking and scanning station 300, the appearance dimension inspection station 400, the end face runout inspection station 500, the wire groove gauge inspection station 600, the air shower cleaning station 700, the sheet gap inspection station 800, the end face inspection station 900 and the product unloading station 1000 in sequence.

[0100] When each of the above workstations has a stator, the equidistant conveying assembly 120 synchronously transports the stator of the current workstation to the next workstation.

[0101] like Figure 1-Figure 6 As shown, the loading station 100 includes a loading chain plate line 110 and an equidistant conveying assembly 120 for transporting the stator located on the loading chain plate line 110;

[0102] The two opposite sides of the feeding chain plate line 110 are symmetrically provided with limit blocks 1111 used in conjunction with the stator, and one side of the limit block 1111 is provided with a proximity sensor 1113;

[0103] The equidistant conveying assembly 120 includes a linear translation module and a transport clamping assembly 123 disposed on the linear translation module. The linear translation module drives the transport clamping assembly 123 to move so as to clamp and transport the stator located between the limit blocks 1111 .

[0104] It should be noted that the stator is located on the loading chain plate line 110 and moves. When it moves to the limit block 1111, the movement of the stator is limited by the limit block 1111. At the same time, the proximity sensor 1113 senses the presence of the stator, and the loading chain plate line 110 stops conveying the stator.

[0105] The linear translation module located on one side of the loading chain line 110 drives the transport clamping assembly 123 to move above the limit block 1111, and clamps and fixes the stator located on the limit block 1111 through the transport clamping assembly 123. The linear translation module drives the transport clamping assembly 123 to move to the next process again to complete the transport of the stator.

[0106] The transport and clamping components 123 are provided in multiple groups, and the multiple groups of transport and clamping components 123 are arranged in an array on the linear translation module.

[0107] It should be noted that the stator test line is provided with multiple test equipment, and multiple transport and clamping assemblies 123 correspond to the multiple test equipment. The stator passes through the multiple test equipment in turn to complete the relevant inspection of the stator. When the multiple test equipment have all completed the relevant tests, the linear translation module drives the transport and clamping assembly 123 to move to the test equipment, and transports the stator that has completed the test equipment to the next test equipment.

[0108] The plurality of transport clamping assemblies 123 are individually controlled.

[0109] The linear translation module includes a lateral translation module 121 and a vertical translation module 122 disposed on the lateral translation module 121 , and the transport clamping assembly 123 is disposed on the lateral translation module 121 .

[0110] Among them, the horizontal translation module 121 and the vertical translation module 122 are linear motion, which can be driven by a screw, a slider, a slide rail, a cylinder, etc. In this embodiment, the slider and the slide rail are preferably started with the cylinder to ensure smoothness during the movement. The related technology in the prior art is relatively mature, so it will not be described in detail.

[0111] The transport clamping assembly 123 includes a clamp lifting cylinder 1231, a clamp cylinder 1232 provided on the clamp lifting cylinder 1231, and a gripper 1233 provided on the clamp cylinder 1232. The clamp cylinder 1232 drives the gripper 1233 to move closer to or away from each other to fix or release the stator.

[0112] The clamping jaw lifting cylinder 1231 adjusts the height position of the gripper 1233 relative to the stator so as to place the gripper 1233 on opposite sides of the stator, and the clamping jaw cylinder 1232 adjusts the relative position of the two grippers 1233 so as to fix or release the stator.

[0113] A receiving block 1234 is provided below the gripper 1233 , and the receiving block 1234 abuts against the bottom of the stator, thereby further ensuring stability during transportation and firmness of stator clamping.

[0114] A buffer member 1235 is disposed at the upper end of the grip 1233 , and a limiting column 1236 used in conjunction with the buffer member 1235 is disposed at the upper end of the other grip 1233 .

[0115] When the two grippers 1233 approach each other, the limiting pillar 1236 abuts against the buffer member 1235 , thereby buffering the force of the grippers 1233 relative to the side wall of the stator, thereby preventing the grippers 1233 from damaging the surface of the stator.

[0116] In addition, a buffer cotton is provided on one side of the gripper 1233 close to the side wall of the stator, and the buffer cotton is provided to avoid rigid contact between the gripper 1233 and the stator.

[0117] The feeding chain plate line 110 is provided with two groups and is divided into a left chain plate line 112 and a right chain plate line 111 , and the left chain plate line 112 and the right chain plate line 111 are arranged side by side.

[0118] Since the client has double-row molds, one mold corresponds to one stator, and the double-row molds of the client are used in rotation at irregular intervals, the corresponding left chain plate line 112 and right chain plate line 111 are set.

[0119] The stator transfer assembly 130 is arranged on opposite sides of the loading chain plate line 110 through a gantry to transfer the stator located on the left chain plate line 112 to the right chain plate line 111, and the stator is concentrated on the right chain plate line 111 for easy transportation.

[0120] The stator transfer assembly 130 includes a transverse transfer module 131 disposed on the gantry, a vertical transfer module 132 disposed on the transverse transfer module 131 , and a loading and transferring clamping claw assembly 133 disposed on the vertical transfer module 132 .

[0121] Among them, the lateral transfer module 131 is used to move the stator of the left chain plate line 112 to the right chain plate line 111, and the vertical transfer module 132 is used to drive the loading and transferring clamping claw assembly 133 to move vertically up and down so as to grab the stator.

[0122] In addition, the structure of the loading and transferring clamping jaw assembly 133 is the same as that of the clamping jaw cylinder 1232.

[0123] A lifting cylinder 1112 is provided at the bottom of the limit stopper 1111, and the limit stopper 1111 is lifted up by the lifting cylinder 1112, thereby suspending the stator in the air for easy transportation.

[0124] When the test line is started, only the loading chain plate line 110 has a stator, and the stator is transported to the angle alignment station 200 through the equidistant conveying component 120.

[0125] like Figure 7-Figure 11 As shown, the angle alignment station 200 includes an angle alignment platform 210 for placing the stator and an angle alignment camera 221 for taking pictures of the stator. A rotating platform 211 is provided on the angle alignment platform 210, and a rotating motor 212 capable of driving the rotating platform 211 to rotate is also provided on one side of the angle alignment platform 210;

[0126] When the angle alignment camera 221 confirms that the angle of the stator is correct, it is ready for transport;

[0127] When the angle alignment camera 221 confirms that the angle of the stator is abnormal, the rotating motor 212 drives the stator to rotate through the rotating platform 211 to complete the angle adjustment of the stator.

[0128] It should be noted that the rotating platform 211 is rotatably connected to the angle alignment platform 210, and the rotating motor 212 can drive the rotating platform 211 to rotate relative to the angle alignment platform 210; since the stator is placed on the rotating platform 211, when the rotating platform 211 rotates, the stator rotates synchronously.

[0129] During use, the stator is placed on the rotating platform 211 through an external device, the angle alignment camera 221 takes a picture of the stator on the rotating platform 211 and sends the data to the rotating motor 212. The rotating motor 212 adjusts the angle of the stator through the rotating platform 211 to facilitate the transportation of the stator to the next workstation for inspection.

[0130] The angle alignment camera 221 is connected to the camera support column 223 via a connecting rod 222 , and the angle alignment camera 221 can move up and down along the height direction of the camera support column 223 .

[0131] The connecting rod 222 is connected to the camera support column 223 through a slide rail, and can move up and down along the height direction of the camera support column 223 to take pictures of the stator for confirmation.

[0132] The connecting rod 222 is further provided with a light source board 224 used in conjunction with the angle alignment camera 221 , and the light source board 224 is provided with a window 2241 for the angle alignment camera 221 to take pictures.

[0133] The light source board 224 is provided to facilitate the angle alignment of the camera 221 so as to take clearer photos.

[0134] A clamping and flipping device 230 connected via a lifting module 240 is provided directly below the angle alignment camera 221 . The clamping and flipping device 230 can clamp and fix the stator on the rotating platform 211 and flip it.

[0135] It should be noted that, during use, the clamping and flipping device 230 and the light source panel 224 will not become dry. The main function of the clamping and flipping device 230 is that it will only be used when the front and back sides of the stator are incorrectly placed. If the front and back sides of the stator are correct when the stator is placed, the clamping and flipping device 230 will not be started; if the angle alignment camera 221 finds that the front and back sides of the stator are incorrectly placed when the stator is placed, the angle alignment camera 221 is reset to the original position of the camera support column 223, and the clamping and flipping device 230 is started to flip the stator placed on the rotating platform 211.

[0136] The clamping and flipping device 230 includes a panel 231 arranged on the lifting module 240 and two clamping arms 232 slidably connected to the panel 231. The inner side of the clamping arm 232 is provided with a clamping claw 233 used in conjunction with the stator. The two clamping claws 233 move closer to or farther away from each other to fix or release the stator.

[0137] Among them, the lifting module 240 is a structure that can drive the panel 231 to move vertically up and down, and can be a cylinder drive, a screw drive, a slide rail structure, etc. In this embodiment, the cylinder and slide rail structure is preferred.

[0138] In addition, the clamping arms 232 are slidably connected to the panel 231 and can move linearly relative to the panel 231. When the clamping arms 232 move away from each other, the stator is located between the two clamping jaws 233; when the clamping arms 232 move closer to each other, the two clamping jaws 233 fix the stator to complete the clamping of the stator.

[0139] The upper and lower ends of the clamping jaw 233 are both provided with L-shaped stoppers 234 , and the upper and lower ends of the stator are limited by the L-shaped stoppers 234 , thereby further ensuring the stability of the stator during clamping and fixing.

[0140] The clamping claw 233 is rotatably mounted on the clamping arm 232 , and the clamping arm 232 is provided with a flip motor 235 capable of driving the clamping claw 233 to rotate.

[0141] When the clamp 233 fixes the stator and the stator rises to a specified height, the flipping motor 235 drives the clamp to rotate relative to the clamp arm 232. Due to the setting of the L-shaped stopper 234 and the clamp 233, the stator rotates synchronously; similarly, due to the presence of the L-shaped stopper 234, the stability of the stator during flipping is further guaranteed.

[0142] A product presence detection sensor 214 is provided on one side of the angle alignment platform 210 .

[0143] The angle alignment platform 210 is provided with an origin sensor 213 of the rotating platform 211 .

[0144] After the above angle detection process is completed, the equidistant conveying assembly 120 is started again, and the stator of the loading chain plate line 110 and the stator of the angle alignment station 200 are synchronously transported. The stator on the loading chain plate line 110 is transported to the angle alignment station 200, and the stator of the angle alignment station 200 is transported to the marking and scanning station 300. The transportation of the two is completed synchronously.

[0145] like Figure 1 , Figure 12-14 As shown, the marking and scanning station 300 is located downstream of the angle alignment station 200, and includes a marking column 310 and a marking machine 331 connected to the marking column 310 through a marking Z-direction translation module 320, a scanning gun 332 and a vacuum cleaner 333. The vacuum cleaner 333 absorbs dust generated by marking on the stator surface, and the scanning gun 332 is used to record the two-dimensional code information of the stator.

[0146] The marking Z-direction translation module 320 is also connected to an outer diameter detection device, which includes a ring gauge hollow platform 340 and an outer diameter ring gauge 341 elastically connected to the ring gauge hollow platform 340 and used in conjunction with the stator;

[0147] A positioning platform 350 for placing the stator is provided inside the ring gauge hollow platform 340 , and a rotating hollow platform motor for driving the positioning platform 350 to rotate is also provided below the positioning platform 350 .

[0148] It should be noted that the marking column 310 is provided with a marking Z-direction translation module 320, one end of which is connected to a marking machine 331, a barcode scanner 332 and a vacuum cleaner 333 through a marking bracket 330; the other end of the marking Z-direction translation module 320 is connected to a ring gauge hollow platform 340.

[0149] The equidistant conveying component 120 places the stator on the positioning table 350, and positions the stator through the positioning table 350. At this time, the marking Z-axis translation module 320 drives the marking machine 331, the barcode scanning gun 332 and the vacuum cleaner 333 to move vertically downward through the marking bracket 330. A stator clamping cylinder is also provided on one side of the marking bracket 330, and a stator clamping plate is provided at the telescopic end of the stator clamping cylinder. When the marking machine 331, the barcode scanning gun 332 and the vacuum cleaner 333 reach the specified position, the stator clamping cylinder drives the stator clamping plate to abut against the upper end surface of the stator to fix the stator on the positioning table 350.

[0150] In addition, the outer diameter of the stator pressing plate is smaller than the outer diameter of the stator.

[0151] After the stator clamping plate fixes the stator, the marking Z-direction translation module 320 drives the ring gauge hollow platform 340 to move vertically upward. During the movement, the outer diameter ring gauge 341 passes through the stator and is able to cover the stator, which indicates that the outer diameter of the stator is qualified. If the outer diameter ring gauge 341 cannot pass through the stator during the movement, the outer diameter ring gauge 341 will abut against the bottom of the stator. Since the outer diameter ring gauge 341 is elastically connected to the ring gauge hollow platform 340, when the outer diameter ring gauge 341 cannot pass through the stator, the marking Z-direction translation module 320 drives the ring gauge hollow platform 340 to return to its initial position, indicating that the outer diameter of the stator is large and unqualified.

[0152] During this process, the marking machine 331 completes the two-dimensional code engraving on the upper end surface of the stator, and the vacuum cleaner 333 is started synchronously during the engraving process to absorb dust. When the engraving is completed, the information of the two-dimensional code is tested by the barcode scanner 332.

[0153] Due to the range requirements of QR code engraving, the position of the stator needs to be rotated during the engraving process. When the angle of the stator needs to be adjusted, the stator clamping plate is separated from the upper end surface of the stator to facilitate the rotation of the central control platform motor 351 to drive the positioning platform 350 to rotate, thereby driving the stator to rotate.

[0154] After the stator marking, code scanning and outer diameter detection are completed, the equidistant conveying component 120 starts to transport the stator from the loading marking and code scanning station 300 to the appearance dimension detection station 400. The specific process has been described above and will not be described in detail here.

[0155] like Figure 1 , Figure 15-19 As shown, the appearance dimension inspection station 400 includes a frame 420, a measuring tool 410 disposed on the frame 420, and a test assembly 440 disposed on the frame 420. The test assembly 440 is slidably connected to the frame 420 through a servo press 430, and can move up and down along the height direction of the frame 420 to test the stator placed on the measuring tool 410.

[0156] The test assembly 440 includes a test bracket 441 detachably connected to the servo press 430. The test bracket 441 is elastically provided with an inner diameter gauge 4423. When the servo press 430 drives the inner diameter gauge 4423 located on the test bracket 441 to move toward the stator, the inner diameter gauge 4423 has two states relative to the stator:

[0157] The inner diameter gauge 4423 enters the interior of the stator, indicating that the inner diameter of the stator meets the standard;

[0158] The inner diameter gauge 4423 abuts against the upper end surface of the stator, indicating that the inner diameter of the stator does not meet the standard.

[0159] It should be noted that the inner diameter gauge 4423 is a standard size and is used to detect the inner diameter of the stator. If the inner diameter of the stator meets the standard, the inner diameter gauge 4423 can be placed in the stator; if the inner diameter of the stator does not meet the standard, the inner diameter gauge 4423 cannot be placed in the stator.

[0160] When the stator is placed on the measuring fixture 410, the servo press 430 drives the inner diameter gauge 4423 to move vertically downward through the test bracket 441, so that the inner diameter gauge 4423 enters the interior of the stator to complete the detection of the inner diameter of the stator;

[0161] When the inner diameter gauge 4423 cannot enter the interior of the stator, the inner diameter gauge 4423 abuts against the upper end surface of the stator. Since the inner diameter gauge 4423 is elastically connected to the test bracket 441, the inner diameter gauge 4423 is prevented from rigidly contacting the upper end surface of the stator, thereby preventing damage to the stator. When the inner diameter gauge 4423 cannot enter the interior of the stator, the servo press 430 drives the inner diameter gauge 4423 to return to its initial position, waiting for the stator to be re-inspected.

[0162] A through gauge bracket 442 is provided inside the test bracket 441, and the through gauge bracket 442 is connected to an inner diameter through gauge 4423 via a telescopic rod 4421. The telescopic rod 4421 extends the inner diameter through gauge 4423 out of the test bracket 441, and a spring 4422 is sleeved on one end of the telescopic rod 4421 located on the inner diameter through gauge 4423; the test bracket 441 is provided with a top measuring sensor 4424 used in conjunction with the telescopic rod 4421.

[0163] If the inner diameter gauge 4423 can enter the interior of the stator, the spring 4422 will not be compressed and the telescopic rod 4421 will not change; if the inner diameter gauge cannot enter the interior of the stator, the spring 4422 will be in a compressed state, and the telescopic rod 4421 will also change. After the top measurement sensor 4424 detects that the telescopic rod 4421 has changed, the servo press 430 drives the inner diameter gauge 4423 to return to the initial position.

[0164] The test assembly 440 also includes a pressure plate 443 disposed at the bottom of the test bracket 441 through a slide rod 4431, and the pressure plate 443 is provided with an opening 4433 for the inner diameter gauge 4423 to pass through. When the pressure plate 443 abuts against the upper end surface of the stator, it can move along the height direction of the slide rod 4431.

[0165] During normal testing and when the inner diameter of the stator meets the standard, the position of the inner diameter gauge 4423 will not change. Since the pressure plate 443 is connected to the test bracket 441 through the sliding rod 4431, when the inner diameter passes into the interior of the stator, the pressure plate 443 abuts against the upper end surface of the stator, and the pressure plate 443 moves relative to the inner diameter gauge 4423 through the sliding rod 4431, and the inner diameter gauge 4423 passes through the opening 4433 and enters the interior of the stator.

[0166] At the same time, when the inner diameter passes into the stator, the pressure plate 443 continuously applies pressure to the upper end surface of the stator, and after the inner diameter enters the stator, the pressure plate 443 maintains the force applied to the upper end surface of the stator to ensure that the upper end surface of the stator is theoretically flat.

[0167] The outer diameter of the pressure plate 443 is smaller than the outer diameter of the test bracket 441 . A height sensor 4434 is provided on one side of the test bracket 441 , and the height of the stator under pressure is tested by the height sensor 4434 .

[0168] A fixing plate 444 is further provided at the bottom of the test bracket 441 . The fixing plate 444 is provided with a plurality of flatness detection sensors 4441 . The pressing plate 443 is provided with through holes 4432 for the flatness detection sensors 4441 to pass through.

[0169] In the above, the movement of the pressure plate 443 relative to the inner diameter gauge 4423 has been improved, and the pressure plate 443 is further abutted against the fixed plate 444. The flatness detection sensor 4441 passes through the through hole 4432 to detect the flatness of the upper end surface of the stator. If the flatness of the upper end surface meets the requirements, the data of multiple flatness detection sensors 4441 should be consistent or the difference should be small.

[0170] A centering rod 447 is provided at the bottom of the test bracket 441 , and a centering hole 411 used in conjunction with the centering rod 447 is provided on the measuring fixture 410 . The centering rod 447 is inserted into the centering hole 411 , thereby further ensuring the accuracy during the pressing process.

[0171] A plurality of support rods 445 are further provided at the bottom of the test bracket 441 , and the plurality of support rods 445 are located on both sides of the centering rod 447 .

[0172] As mentioned above, the test assembly 440 is detachably connected to the servo press 430. When the test assembly 440 is detached, the test assembly 440 is supported by a plurality of support rods 445 to prevent the inner diameter gauge 4423 from directly contacting the ground.

[0173] The telescopic end of the servo press 430 is provided with a fixing seat connected to the test bracket 441 , and the fixing seat and the test bracket 441 are detachably connected by bolts, so as to facilitate replacement of the adapted test assembly 440 according to different workpieces.

[0174] There are many ways to disassemble, and bolt fixing is preferred in this embodiment.

[0175] An arc-shaped bracket 446 is disposed on one side of the test bracket 441 , and the frame 420 is detachably inserted into a guide rod 421 used in conjunction with the arc-shaped bracket 446 .

[0176] The servo press 430 drives the test assembly 440 to move downward to the specified position. At this time, the arc bracket 446 abuts against the guide rod 421, and the personnel removes the bolts between the test bracket 441 and the fixed seat. After the disassembly is completed, the personnel pulls the test assembly 440 along the direction of the guide rod 421 to take out the test assembly 440.

[0177] The replacement of the test component 440 adopts the same operation method and will not be described in detail here.

[0178] After the appearance and size inspection of the stator is completed, the equidistant conveying assembly starts to transport the stator from the appearance and size inspection station to the end face runout station. The specific process has been described above and will not be described in detail here.

[0179] like Figure 1 and Fig. 20 As shown, the end face runout detection station 500 is located downstream of the appearance dimension detection station 400, and includes an end face runout detection column 510. The end face runout detection column 510 is connected to a stator tensioning and rotating device through an end face Z-direction translation module 520, and is used to detect the upper and lower end face runout of the stator in a rotating state.

[0180] The stator tightening and rotating device comprises an end face bracket 530 connected to the end face Z-direction translation module 520, a hollow rotating servo 533 provided on the end face bracket 530, and a tooling tightening assembly connected to the hollow rotating servo 533, wherein the tooling tightening assembly comprises a tooling tightening cylinder 532 located at the upper end of the hollow rotating servo 533 and a tooling tightening head 531 connected to the hollow rotating servo 533 and extending out of one end of the hollow rotating servo 533 and used in conjunction with the stator;

[0181] The end face bracket 530 is provided with an upper distance measuring sensor 540 for detecting the vibration of the upper end face of the stator, and a lower distance measuring sensor 541 for use with the upper distance measuring sensor 540 is provided below the upper distance measuring sensor 540 .

[0182] It should be noted that the end face runout detection station 500 is also provided with a positioning platform for placing the stator to define and fix the position of the stator, so the specific structure will not be described in detail.

[0183] When the equidistant conveying assembly 120 places the stator on the positioning table, the end surface Z-direction translation module 520 drives the end surface bracket 530 to move. When the tooling tensioning head 531 is placed on the inner wall of the stator, the tooling tensioning cylinder 532 is started to fix the stator through the tooling tensioning head 531. After the stator is fixed, the end surface Z-direction translation module 520 drives the end surface bracket 530 to move vertically upward to the specified position, and drives the stator to move synchronously. When the stator reaches the specified position, since the hollow rotating servo 533 is connected to the tooling tensioning assembly, the stator located at the tooling tensioning head 531 is driven to rotate through the hollow rotating servo 533.

[0184] During the rotation of the stator, the upper distance measuring sensor 540 and the lower distance measuring sensor 541 are provided to detect the vibration of the upper end surface and the lower end surface of the stator.

[0185] When the test is completed, the equidistant conveying assembly 120 starts to transport the stator of the end face runout detection station 500 to the wire slot gauge detection station 600. The specific process has been described above and will not be described in detail here.

[0186] like Figure 1 , Figure 21-22 As shown, the wire slot through gauge detection station 600 is located downstream of the end face runout detection station 500, and includes a through gauge column 610, and the through gauge column 610 is connected to a wire slot through gauge assembly 630 through a through gauge Z-direction translation module 620, and is used to detect the passability of the wire slot inside the stator;

[0187] The wire slot gauge assembly 630 includes a wire slot bracket 631 connected to the gauge Z-direction translation module 620, the wire slot bracket 631 is provided with a plurality of bar gauges 632, and the bottom of the wire slot bracket 631 is connected to a guide plate 633 via a guide rod;

[0188] Among them, the size of the bar go gauge 632 is the same as the size of the wire slot. Therefore, if the bar go gauge 632 can be inserted into the wire slot of the stator, it indicates that the size of the wire slot of the stator is qualified. If the bar go gauge 632 cannot be inserted into the wire slot of the stator, it indicates that the size of the wire slot of the stator is unqualified.

[0189] The guide plate 633 can move up and down along the height direction of the guide rod, and the guide plate 633 is provided with a guide groove for the bar gauge 632 to pass through.

[0190] One end of the bar gauge 632 passes through the wire slot bracket 631 and the guide plate 633 in sequence, and the other end of the bar gauge 632 is movably connected to the fixing plate provided on the wire slot bracket 631 through a connecting assembly.

[0191] Similarly, the wire slot gauge inspection station 600 is provided with a positioning platform for placing the stator. When the stator is placed in place, the gauge Z-axis translation module 620 drives the bar gauge 632 to move vertically downward through the wire slot bracket 631. When one end of the bar gauge 632 contacts the wire slot, the guide plate 633 also abuts against the upper end surface of the stator, and the wire slot bracket 631 continues to move downward. Due to the action of external force, the guide plate 633 moves vertically upward along the height direction of the guide rod. During this process, the guide plate 633 always abuts against the upper end surface of the stator until the bar gauge 632 is fully inserted into the wire slot.

[0192] A baffle is disposed at the upper end of the connection assembly, and the wire trough bracket 631 is provided with a through gauge sensor used in conjunction with the baffle.

[0193] The above process describes that the bar go gauge 632 can be inserted into the wire slot. When the bar go gauge 632 cannot be inserted into the wire slot, the bar go gauge 632 abuts against the upper end surface of the stator or is stuck in the wire slot. The bar go gauge 632 is subjected to external force, causing the bar go gauge 632 to move relative to the fixed plate through the connecting component. During the movement, the baffle plate provided on the connecting component triggers the go gauge sensor, thereby stopping the descending process of the wire slot bracket 631, and then the wire slot bracket 631 returns to its initial position, indicating that the wire slot size of the stator is unqualified.

[0194] In addition, the positioning table of the workbench can drive the stator to rotate. After the first wire slot size detection is completed, the stator is driven to rotate a wire slot angle and the wire slot size is tested again. The two test processes are the same.

[0195] When the test is completed, the equidistant conveying assembly 120 starts to transport the stator of the wire slot gauge inspection station 600 to the air shower cleaning station. The specific process has been described above and will not be described in detail here.

[0196] like Figure 1 and Fig.23 As shown, the air shower cleaning station 700 is located downstream of the wire trough gauge inspection station, and includes an air shower column 710. The air shower column 710 is connected to a sealing cover 730 through an air shower Z-direction translation module 720. A plurality of ion air guns 731 are arranged in the sealing cover 730. A tray platform 740 for placing a stator and cooperating with the sealing cover 730 is arranged below the ion air gun 731. The sealing cover 730 covers the tray platform 740, and the stator is cleaned by the ion air gun 731.

[0197] Among them, the tray platform 740 includes a base plate used in conjunction with the sealing cover 730 and a positioning platform arranged on the base plate. The positioning platform can drive the stator to rotate. The relevant structure has been mentioned above and is a relatively mature technology in the prior art, so it will not be described in detail.

[0198] When the stator is placed on the positioning table, the air shower Z-direction translation module 720 drives the sealing cover 730 to move downward so that the sealing cover 730 covers the bottom plate. At this time, multiple ion air guns 731 are respectively located inside and outside the stator, etc. The ion air guns 731 are started and the stator rotates synchronously so that the ion air guns 731 can clean the stator.

[0199] When the cleaning is completed, the equidistant conveying assembly 120 starts to transport the stator of the air shower cleaning station 700 to the sheet gap detection station 800. The specific process has been described above and will not be described in detail here.

[0200] like Fig.24 As shown, the sheet gap detection station 800 is located downstream of the air shower cleaning station 700, and includes a lower rotating platform servo 810 on which the stator is placed, a first camera 820 and a second camera 830. The lower rotating platform servo 810 drives the stator to rotate, and uses the first camera 820 and the second camera 830 to take photos of the gap between each silicon steel sheet of the stator for detection.

[0201] Among them, the first camera 820 is an area array camera, and the second camera 830 is a line scan camera. Both cameras are conventional components in the prior art. When the stator rotates, they can clearly capture the situation between each gap of the silicon steel sheet. Therefore, their working principles are no longer described in detail.

[0202] After the photographic inspection is completed, the equidistant conveying assembly 120 starts to transport the stator of the gap inspection station 800 to the end surface inspection station 900. The specific process has been described above and will not be described in detail here.

[0203] like Figure 1 , Figure 7-Figure 11 , Fig.25 As shown, the end face inspection station 900 is located downstream of the gap inspection station 800, and is used to take photos and inspect the appearance of the stator. The structure of the end face inspection station 900 is basically the same as that of the angle alignment station 200. The only difference is that the cameras used in the two stations are not of the same functional models. The overall operating principle of the end face inspection station 900 refers to the angle alignment station, so it will not be described in detail.

[0204] The end face inspection station 900 is mainly used to take photos and inspect the defects on the stator appearance.

[0205] After the appearance inspection of the stator is completed, the equidistant conveying assembly 120 starts to transport the stator of the end surface inspection station 900 to the product unloading station 1000. The specific process has been described above and will not be described in detail here.

[0206] like Figure 1 , Figure 26-Figure 27As shown, the product unloading station 1000 is located downstream of the end face inspection station 900, and includes a three-axis module 1010, an NG track line 1030, an OK track line 1040, an unloading load-bearing platform and an oil injection device 1050. The three-axis module 1010 transports the stator on the unloading weighing platform 1020 to the OK track line 1040 or the NG track line 1030 respectively; the oil injection device 1050 is arranged on the OK track line 1040 to spray the OK stator with oil.

[0207] The oil injection device 1050 includes an oil injection protection cover 1051 used in conjunction with the OK track line 1040 and an oil injection nozzle 1052 arranged on the oil injection protection cover 1051.

[0208] The equidistant conveying assembly transports the stators of the end face inspection station 900 to the unloading weighing platform 1020 for weighing processing, and the three-axis module 1010 transports the qualified stators to the OK track line 1040 and the unqualified stators to the NG track line 1030.

[0209] The stator stops moving after moving to the designated position on the OK track line 1040, and the oil spray protection cover 1051 descends to cover the OK track line 1040. At the same time, the oil spray nozzle 1052 sprays oil to the stator. After the oil spraying is completed, the oil spray nozzle 1052 stops spraying oil, the air nozzle blows air, and the oil mist separator works. When the oil spray protection cover 1051 returns to the initial position, the stator flows out.

[0210] In the above, the working mode of the fuel injector 1052 and the principle of the oil mist separator are very mature in the prior art, so they are not described in detail.

[0211] At this point, all testing and cleaning processes of the stator are completed. At this point, there is a stator in each workstation. When the work of each workstation is completed, the equidistant conveying component 120 synchronously transports the stator of the current workstation to the next workstation.
