Description

Technical Field

[0001] The present invention relates to the field of detection equipment, and particularly to a power-on test equipment for an improved canned motor pump. Background Art

[0002] During the production process of a canned motor pump, a power-on test equipment is required to perform a power-on test on the rotor of the canned motor pump.

[0003] There is a rotor of an existing improved canned motor pump as Figure 20 shown. A connection plug is provided on the rotor. When performing a power-on test on the rotor of the pump body, technicians need to first sleeved the rotor onto the fixed rod of the power-on test equipment, and then the technicians insert the detection plug of the power-on test equipment into the connection plug to connect the rotor with the power-on test equipment, and then the power-on test equipment can detect the power-on performance of the rotor.

[0004] The method of manually docking the plugs has low detection efficiency. In the detection of one rotor, technicians spend most of their time plugging and unplugging the two plugs. In order to improve the detection efficiency of the rotor, it is necessary to realize the automatic plugging and unplugging of the detection plug and the connection plug of the power-on test equipment. Summary of the Invention

[0005] The present application provides a power-on test equipment for an improved canned motor pump, which can automatically plug and unplug the detection plug and the connection plug, and improve the detection efficiency of the canned motor pump.

[0006] The power-on test equipment for an improved canned motor pump provided by the present application adopts the following technical solutions:

[0007] A power-on test equipment for an improved canned motor pump includes a machine body, a fixed rod provided on the machine body for sleeving the rotor, a pressing plate provided on the fixed rod, and a detection plug provided on the machine body. The machine body is slidably connected with a mounting seat along the X-axis direction. The detection plug is provided on the mounting seat. The detection plug is located between the mounting seat and the fixed rod. The machine body is provided with a first control mechanism for controlling the mounting seat to slide so that the mounting seat moves closer to or away from the fixed rod. A first gear is rotatably connected to the fixed rod, and a pressing block is provided on the first gear. A limiting block is provided on the pressing plate, and the limiting block is located on the rotation path of the pressing block. The rotor is sleeved and rotatably connected to the fixed rod, and when the rotor abuts against the pressing plate, the connection plug is located on the rotation path of the pressing block. The machine body is provided with a second control mechanism for controlling the rotation of the first gear. The second control mechanism controls the first gear to reverse to drive the pressing block to move closer to the limiting block and press the connection plug against the limiting block. When the connection plug is pressed against the limiting block by the pressing block, the connection plug is aligned with the detection plug and located on the movement path of the detection plug.

[0008] By adopting the above technical solution, the technician sleeved the rotor on the fixed rod and made the connection plug located between the limit block and the pressing block. Then, the second driving mechanism drives the first gear to reverse, causing the pressing block to rotate and push the connection plug to rotate. Finally, the pressing block presses the connection plug against the limit block, completing the alignment of the connection plug and the detection plug. There is no need for manual adjustment, reducing the sleeving requirements for the rotor and facilitating the technician to sleeve the rotor. Then, the first driving mechanism drives the mounting seat to slide, making the detection plug move closer to the connection plug and finally plugging them together, and then the detection of the rotor can start. After the detection is completed, the first driving mechanism drives the mounting seat to slide back to separate the detection plug from the connection plug. At the same time, the second driving mechanism drives the first gear to rotate back to cancel the pressing of the pressing block on the connection plug, and then the rotor can be removed from the fixed rod.

[0009] Preferably, the first control mechanism includes a motor provided on the machine body, a first rotating rod provided on the output shaft of the motor, a second gear sleeved on the first rotating rod, and a first rack provided on the mounting seat. The second gear meshes with the first rack. When the first rotating rod rotates forward, it drives the mounting seat to move closer to the fixed rod through the cooperation of the second gear and the first rack; when the first rotating rod rotates backward, it drives the mounting seat to move away from the fixed rod through the cooperation of the second gear and the first rack.

[0010] By adopting the above technical solution, by driving the first rotating rod to rotate forward and backward by the motor, the movement of the mounting seat can be controlled, thereby controlling the insertion and extraction of the connection plug and the detection plug.

[0011] Preferably, the second control mechanism includes a third gear provided on the first rotating rod. The third gear meshes with the first gear. When the first rotating rod rotates forward, it drives the first gear to reverse through the third gear; when the first rotating rod rotates backward, it drives the first gear to rotate forward through the third gear.

[0012] By adopting the above technical solution, when the first rotating rod rotates forward and backward, it can drive the first gear to rotate forward and backward through the third gear.

[0013] Preferably, a first sliding groove is formed on the mounting seat. A T-shaped block is slidably connected in the first sliding groove along the X-axis direction. The smaller end of the T-shaped block extends out of the mounting seat. The detection plug is located between the mounting seat and the fixed rod. A third control mechanism is further provided on the machine body, and the third control mechanism is used to control the movement of the T-shaped block.

[0014] By adopting the above technical solution, during the movement of the mounting base towards the rotor, the third control mechanism drives the T-shaped block to move into the first chute, causing the detection plug to move closer to the mounting base, so that the detection plug will not be docked with the connection plug during the movement of the mounting base, preventing the situation of inaccurate docking and mutual collision between the two. After the pressing block presses the connection plug against the limiting block and the mounting base stops moving, the third driving mechanism drives the T-shaped block to move out of the first chute, thereby driving the detection plug to move towards the connection plug and finally enabling the detection plug to be inserted into the connection plug.

[0015] Preferably, the third control mechanism includes a first spring disposed in the first chute, a pull rod rotatably connected to the mounting base, a pull rope disposed on the pull rod, a first one-way bearing sleeved on the pull rod, a first rubber wheel sleeved on the outer ring of the first one-way bearing, and a first friction rail disposed on the machine body and in contact with the first rubber wheel; the first spring is located on the side of the T-shaped block away from the detection plug, and the first spring always drives the T-shaped block to move towards the fixed rod. When there is no external force, the first spring presses the T-shaped block against the side wall of the first chute close to the fixed rod; the end of the pull rope away from the pull rod extends into the first chute and is connected to the T-shaped block. When the pull rod rotates, the pull rope is wound to drive the T-shaped block to move into the first chute and compress the first spring; during the movement of the mounting base close to the fixed rod, the first rubber wheel rubs against the first friction rail and rotates forward, and the forward rotation of the first rubber wheel drives the outer ring of the first one-way bearing to rotate forward; the forward rotation of the outer ring of the first one-way bearing drives the inner ring of the first one-way bearing and the pull rod to rotate forward; when the mounting base moves to the position closest to the fixed rod, the first rubber wheel moves away from the first friction rail.

[0016] By adopting the above technical solution, during the movement of the mounting base close to the fixed rod, the first rubber wheel will rotate forward under the action of friction and drive the inner and outer rings of the first one-way bearing and the pull rod to rotate forward together. The rotation of the pull rod winds the pull rope to enable the T-shaped block to slide into the first chute and compress the first spring, causing the detection plug to move closer to the mounting base, so that the detection plug will not be docked with the connection plug during the movement of the mounting base. After the mounting base stops moving close to the fixed rod, the first friction rail is separated from the first rubber wheel, and the first spring will rebound and drive the T-shaped block to move close to the fixed rod so that the detection plug is docked with the connection plug.

[0017] Preferably, an installation groove is formed in the first friction rail. A guide rod is slidably connected in the installation groove along the X-axis direction. An avoidance groove is formed in the side wall of the installation groove. A friction block is provided on the guide rod. The friction block extends out of the first friction rail through the avoidance groove. The friction block is located on the movement path of the pull rod. A second spring is arranged in the installation groove. The second spring is located on the side of the pull rod away from the fixed rod. The second spring is connected to the pull rod. The elastic force of the first spring is greater than that of the second spring. When the pull rod moves closer to the fixed rod, it will contact the friction block and push the friction block and the guide rod to move closer to the fixed rod, causing the second spring to be stretched under force.

[0018] By adopting the above technical solution, during the process of the mounting seat sliding closer to the fixed rod, the pull rod will contact the friction block and push the friction block and the guide rod to move closer to the fixed rod. Once the first friction rail is separated from the first rubber wheel, the first spring will drive the pull rod to rotate. The rotation of the pull rod will drive the first one-way bearing and the first friction wheel to rotate. However, under the action of the second spring, the friction block will always press against the pull rod, generating friction between the friction block and the pull rod, so that the pull rod rotates at a uniform speed, thereby preventing the second spring from rebounding instantaneously and driving the T-shaped block to move closer to the fixed rod. Finally, the purpose of prolonging the movement time of the detection plug is achieved, so that the detection plug will move to dock with the connection plug only after the pressing block presses the connection plug against the limiting block, improving the docking accuracy of the detection plug and the connection plug. After the equipment has been used for a period of time, the connections between the friction block and the pull rod are worn, but under the action of the second spring, it can always be ensured that the friction block is in contact with the pull rod when the pull rod rotates, so as to ensure that the friction block will always produce a decelerating effect on the pull rod when the pull rod rotates.

[0019] Preferably, a second sliding groove is formed in the machine body. A sliding rod is slidably connected in the second sliding groove along the Y-axis direction. The pressing plate is slidably connected to the fixed rod along the Y-axis direction. One end of the sliding rod extends out of the second sliding groove and is connected to the pressing plate. The machine body is further provided with a fourth control mechanism for controlling the sliding of the sliding rod. After the rotor detection is completed, the fourth control mechanism controls the sliding of the sliding rod so that the pressing plate moves to push the rotor out of the fixed rod.

[0020] By adopting the above technical solution, after the rotor detection is completed, the fourth control mechanism controls the sliding rod to slide away from the second sliding groove so that the pressing plate pushes the rotor to move, and finally the pressing plate pushes the rotor out of the fixed rod, completing the automatic blanking of the rotor.

[0021] Preferably, the fourth control mechanism includes a connection block disposed on the sliding rod, a third spring disposed in the second chute, and a control component for driving the sliding rod to move out of the second chute. The third spring is sleeved on the sliding rod. The third spring is located on the side of the connection block close to the abutting plate. The elastic force of the third spring acts on the connection block. The first gear is located between the abutting plate and the connection block. The third spring always drives the connection block to move away from the first gear. The control component controls the sliding rod to move away from the second chute so that the abutting plate moves away from the first gear and pushes the rotor out of the fixing rod.

[0022] By adopting the above technical solution, after the rotor detection is completed, the control component controls the sliding rod and the connection block to move away from the second chute so that the abutting plate pushes the detected rotor out of the fixing rod. When the connection block moves away from the second chute, it will squeeze the third spring so that the third spring is compressed under force. After the rotor is pushed out of the fixing rod, the control component cancels the force applied to the sliding rod, and the third spring will rebound to drive the connection block and the sliding rod to reset, thereby driving the abutting plate to move back to its original position.

[0023] Preferably, the control component includes a second rotating rod rotatably connected to the machine body, a second one-way bearing disposed on the second rotating rod, a second rubber wheel sleeved on the outer ring of the second one-way bearing, a second friction rail disposed on the mounting seat and used to abut against the second rubber wheel, a fourth gear disposed on the second rotating rod, and a second rack disposed on the sliding rod and meshing with the fourth gear; the outer ring of the first one-way bearing does not drive the inner ring of the first one-way bearing to rotate during forward rotation; in the initial state, the second friction rail does not contact the second rubber wheel; during the process of the mounting seat moving close to the fixing rod, the second friction rail contacts the second rubber wheel and drives the second rubber wheel and the outer ring of the second one-way bearing to rotate forward; during the process of the mounting seat moving away from the fixing rod, the second friction rail contacts the second rubber wheel and drives the second rubber wheel and the outer ring of the second one-way bearing to rotate in reverse; before the second friction rail drives the second rubber wheel to rotate in reverse, the detection plug has been detached from the connection plug; when the second rotating rod rotates in reverse, it drives the sliding rod and the connection block to move out of the second chute through the cooperation of the fourth gear and the second rack.

[0024] By adopting the above technical solution, during the process of the mounting base sliding away from the fixed rod, first, it is detected that the plug is detached from the connecting plug. Then, the second friction rail will move to contact the second rubber wheel and drive the second rubber wheel to reverse. The reverse rotation of the second rubber wheel will drive the second rotating rod to reverse through the second one-way bearing. When the second rotating rod reverses, it will drive the sliding rod to slide away from the second sliding groove through the cooperation of the fourth gear and the second rack. When the sliding rod moves away from the second sliding groove, it will drive the abutting plate to move away from the first gear. When the abutting plate moves away from the first gear, it will push the rotor to move, and finally push the rotor out of the fixed rod, completing the automatic blanking of the rotor. During the process of the mounting base moving away from the fixed rod, the second friction rail will move away from the second rubber wheel. Once the two are separated, the third spring will push the connecting block to move into the second sliding groove and make the sliding rod move into the second sliding groove. When the sliding rod moves into the second sliding groove, it will drive the abutting plate to move back to its original position.

[0025] The technical effects of the present invention are mainly reflected in the following aspects:

[0026] 1. The present invention can automatically complete the automatic docking of the connecting plug and the detection plug;

[0027] 2. The present invention improves the accuracy of the docking between the connecting plug and the detection plug by delaying the action of the detection plug;

[0028] 3. The present invention can automatically push the rotor out of the fixed rod after the detection is completed, facilitating the detection of the next rotor. Description of the Drawings

Specific embodiments

[0050] The present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solutions of the present application are easier to understand and master.

[0051] Referring to Figure 1 , a power-on test device for an improved canned motor pump in this embodiment includes a body 1, a fixing rod 11 fixed on the body 1 for sleeving a rotor 8, an abutting plate 12 mounted on the fixing rod 11, and a detection plug 9 mounted on the body 1. The axis of the fixing rod 11 is parallel to the Y axis.

[0052] Referring to Figures 1 - 3 , a mounting seat 13 is slidably connected to the body 1 in the X-axis direction, and a first control mechanism 2 is provided on the body 1. The first control mechanism 2 is used to control the sliding of the mounting seat 13 so that the mounting seat 13 moves closer to or away from the fixing rod 11.

[0053] Referring to Figures 1 - 4 , the axis of the first rotating rod 22 is parallel to the axis of the fixing rod 11. The second gear 23 meshes with the first rack 24. When the first rotating rod 22 rotates forward, the mounting seat 13 is driven to move closer to the fixing rod 11 through the cooperation of the second gear 23 and the first rack 24; when the first rotating rod 22 rotates reversely, the mounting seat 13 is driven to move away from the fixing rod 11 through the cooperation of the second gear 23 and the first rack 24.

[0054] Referring to Figures 1 - 4, a first gear 14 is rotatably connected to a fixing rod 11, and a pressing block 15 is fixed on the first gear 14. A limiting block 16 is provided on the pressing plate 12, and the limiting block 16 is located on the rotation path of the pressing block 15; the rotor 8 is sleeved and rotatably connected to the fixing rod 11, and when the rotor 8 abuts against the pressing plate 12, the connecting plug 81 is located on the rotation path of the pressing block 15.

[0055] Refer to Figures 1 - 4 , a second control mechanism 3 for controlling the rotation of the first gear 14 is provided on the machine body 1. The second control mechanism 3 controls the first gear 14 to reverse so as to drive the pressing block 15 to move closer to the limiting block 16 and press the connecting plug 81 against the limiting block 16. When the connecting plug 81 is pressed against the limiting block 16 by the pressing block 15, the connecting plug 81 is facing the detection plug 9 and is located on the movement path of the detection plug 9.

[0056] Refer to Figures 1 - 4 , the second control mechanism 3 includes a third gear 31 fixed on a first rotating rod 22. The third gear 31 meshes with the first gear 14. When the first rotating rod 22 rotates forward, the first gear 14 is driven to reverse through the third gear 31; when the first rotating rod 22 rotates reversely, the first gear 14 is driven to rotate forward through the third gear 31.

[0057] Refer to Figure 1 and Figure 4 , a first sliding groove 131 is formed in the mounting seat 13. A T-shaped block 132 is slidably connected in the first sliding groove 131 along the X-axis direction. The smaller end of the T-shaped block 132 extends out of the mounting seat 13. The detection plug 9 is installed at the end of the T-shaped block 132 extending out of the mounting seat 13, and the detection plug 9 is located between the mounting seat 13 and the fixing rod 11.

[0058] Refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 12 and Figure 13 , a third control mechanism 4 is further provided on the machine body 1. The third control mechanism 4 is used to control the movement of the T-shaped block 132. The third control mechanism 4 includes a first spring 41 provided in the first sliding groove 131, a pull rod 42 rotatably connected to the mounting seat 13, a pull rope 43 with one end fixed on the pull rod 42, a first one-way bearing 44 sleeved on the pull rod 42, a first rubber wheel 45 sleeved on the outer ring of the first one-way bearing 44, and a first friction rail 46 fixed on the machine body 1 and abuting against the first rubber wheel 45.

[0059] Refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 12 and Figure 13, the first spring 41 is located on the side of the T-shaped block 132 away from the detection plug 9. The first spring 41 always drives the T-shaped block 132 to move towards the fixed rod 11. When there is no external force, the first spring 41 presses the T-shaped block 132 against the side wall of the first chute 131 close to the fixed rod 11. The axis of the pull rod 42 is parallel to the axis of the first rotating rod 22. One end of the pull rope 43 away from the pull rod 42 extends into the first chute 131 and is connected to the T-shaped block 132. When the pull rod 42 rotates, the pull rope 43 is wound to drive the T-shaped block 132 to move into the first chute 131 and compress the first spring 41. During the process of the mounting seat 13 moving closer to the fixed rod 11, the first rubber wheel 45 rotates by friction with the first friction rail 46 and drives the inner ring of the first one-way bearing 44 and the pull rod 42 to rotate. When the mounting seat 13 moves to the position closest to the fixed rod 11, the first rubber wheel 45 moves away from the first friction rail 46.

[0060] Refer to Figures 5 - 7 , an installation groove 61 is formed in the first friction rail 46. A guide rod 62 is slidably connected in the installation groove 61 along the X-axis direction. One end of the guide rod 62 close to the fixed rod 11 extends out of the installation groove 61; an avoidance groove 63 is formed in the side wall of the installation groove 61. A friction block 64 is provided on the guide rod 62, and the friction block 64 extends out of the first friction rail 46 through the avoidance groove 63. A second spring 65 is fixed in the installation groove 61. The second spring 65 is located on the side of the guide rod 62 away from the fixed rod 11. One end of the second spring 65 is connected to the side wall of the installation groove 61 away from the fixed rod 11, and the other end of the second spring 65 is fixedly connected to the pull rod 42. The elastic force of the first spring 41 is greater than the elastic force of the second spring 65. During the process of the pull rod 42 moving closer to the fixed rod 11, it will contact the friction block 64 and push the friction block 64 and the guide rod 62 to move closer to the fixed rod 11 and stretch the second spring 65.

[0061] Refer to Figure 1 , Figure 2 , Figure 8 and Figure 9 , the abutting plate 12 is slidably connected to the fixed rod 11 along the Y-axis direction. A second chute 17 is formed in the machine body 1. A sliding rod 18 is slidably connected in the second chute 17 along the Y-axis direction. One end of the sliding rod 18 extends out of the second chute 17 and is fixedly connected to the abutting plate 12.

[0062] Refer to Figure 1 , Figure 2 , Figures 8 - 10, a fourth control mechanism 5 for controlling the sliding of the sliding rod 18 is further provided on the body 1. After the detection of the rotor 8 is completed, the fourth control mechanism 5 controls the sliding of the sliding rod 18 so that the abutting plate 12 moves away from the first gear 14 and pushes the rotor 8 out of the fixing rod 11. The fourth control mechanism 5 includes a connecting block 51 fixed on the sliding rod 18 and a third spring 52 provided in the second chute 17. The third spring 52 is sleeved on the sliding rod 18. The third spring 52 is located on the side of the connecting block 51 close to the abutting plate 12. The elastic force of the third spring 52 acts on the connecting block 51, and the third spring 52 always drives the connecting block 51 to move away from the abutting plate 12. When there is no external force, the third spring 52 presses the connecting block 51 against the side wall of the third chute away from the abutting plate 12.

[0063] Refer to Figure 1 , Figure 2 , Figures 8 - 10 , the fourth control mechanism 5 further includes a control component 53 for driving the sliding rod 18 to move out of the second chute 17. The control component 53 controls the sliding rod 18 to move away from the second chute 17 so that the abutting plate 12 moves away from the first gear 14. The control component 53 includes a second rotating rod 531 rotatably connected to the body 1, a second one-way bearing 532 provided on the second rotating rod 531, a second rubber wheel 533 sleeved on the outer ring of the second one-way bearing 532, a second friction rail 534 provided on the mounting seat 13 and used to abut against the second rubber wheel 533, a fourth gear 535 provided on the second rotating rod 531, and a second rack 536 provided on the sliding rod 18 and meshing with the fourth gear 535. The axis of the second rotating rod 531 is parallel to the Z-axis, and the second rotating rod 531 is located between the mounting seat 13 and the body 1.

[0064] Refer to Figure 2 , Figure 14 , Figure 17 , Figure 18 , the outer ring of the first one-way bearing 44 does not drive the inner ring of the first one-way bearing 44 to rotate during forward rotation. In the initial state, the second friction rail 534 is not in contact with the second rubber wheel 533; during the process of the mounting seat 13 moving close to the fixing rod 11, the second friction rail 534 contacts the second rubber wheel 533 and drives the second rubber wheel 533 and the outer ring of the second one-way bearing 532 to rotate forward. During the process of the mounting seat 13 moving away from the fixing rod 11, the second friction rail 534 contacts the second rubber wheel 533 and drives the second rubber wheel 533 and the outer ring of the second one-way bearing 532 to rotate in reverse. Before the second friction rail 534 drives the second rubber wheel 533 to rotate in reverse, the detection plug 9 has been detached from the connection plug 81. The reverse rotation of the outer ring of the second one-way bearing 532 will drive the inner ring of the second one-way bearing 532 and the second rotating rod 531 to rotate in reverse. When the second rotating rod 531 rotates in reverse, it drives the sliding rod 18 and the connecting block 51 to move out of the second chute 17 through the cooperation of the fourth gear 535 and the second rack 536.

[0065] The specific detection steps of the power-on test equipment of this application are as follows:

[0066] Referring to Figure 1 、 Figure 2 、 Figures 11 - 13 ,technicians sleeved the rotor 8 on the fixed rod 11, and made the connection plug 81 located between the limit block 16 and the pressing block 15, and then the motor 21 was started to drive the first rotating rod 22 to rotate forward. When the first rotating rod 22 rotates forward, it will drive the mounting seat 13 to move closer to the rotor 8 through the cooperation of the second gear 23 and the first rack 24. During the process of the mounting seat 13 moving closer to the rotor 8, the first rubber wheel 45 rubs against the first friction rail 46 and rotates forward. The forward rotation of the first rubber wheel 45 will drive the inner ring of the first one-way bearing 44 and the pull rod 42 to rotate forward. During the forward rotation of the pull rod 42, the pull rope 43 will be wound to make the T-shaped block 132 slide into the first chute 131 and squeeze the first spring 41, so that the detection plug 9 moves closer to the mounting seat 13, so that the detection plug 9 will not be docked with the connection plug 81 during the movement of the mounting seat 13.

[0067] Referring to Figure 1 、 Figure 2 、 Figures 14 - 16 ,during the process of the mounting seat 13 sliding closer to the rotor 8, the pull rod 42 abuts against the friction block 64 and will push the friction block 64 and the guide rod 62 to move closer to the fixed rod 11, so that the guide rod 62 and the friction block 64 move out of the first friction rail 46. At the same time, during the process of the mounting seat 13 sliding closer to the rotor 8, the second friction rail 534 will contact the second rubber wheel 533 and drive the second rubber wheel 533 to rotate forward, and the forward rotation of the second rubber wheel 533 will cause the outer ring of the second one-way bearing 532 to rotate forward idly.

[0068] Referring to Figure 1 、 Figure 2 、 Figure 11 、 Figure 14 ,during the forward rotation of the first rotating rod 22, the first rotating rod 22 will drive the first gear 14 to rotate reversely through the third gear 31, and the reverse rotation of the first gear 14 causes the pressing block 15 to rotate and push the connection plug 81 to rotate. Finally, the reverse rotation of the first gear 14 causes the pressing block 15 to rotate and push the connection plug 81 to rotate. Finally, the pressing block 15 presses the connection plug 81 against the limit block 16.

[0069] Referring to Figure 1 、 Figure 2 、 Figures 11 - 16When the pressing block 15 moves to press the connecting plug 81 against the limiting block 16, the first rotating rod 22 stops rotating, and at the same time, the mounting seat 13 also stops moving. After the mounting seat 13 stops moving, the first friction rail 46 disengages from the first rubber wheel 45, and the first spring 41 will rebound and drive the T-shaped block 132 and the detection plug 9 to move closer to the connecting plug 81 so that the detection plug 9 is docked with the connecting plug 81.

[0070] Refer to Figure 1 , Figure 2 , Figures 11 - 16 , during the rebound process of the first spring 41, the first spring 41 will drive the pull rod 42 to rotate back. However, under the action of the second spring 65, the friction block 64 will always press against the pull rod 42, causing a frictional force between the friction block 64 and the pull rod 42 so that the pull rod 42 rotates uniformly, thereby preventing the first spring 41 from instantly rebounding and driving the T-shaped block 132 to move closer to the fixed rod 11. Finally, the purpose of extending the movement time of the detection plug 9 is achieved, so that the detection plug 9 will move to dock with the connecting plug 81 only after the pressing block 15 presses the connecting plug 81 against the limiting block 16, improving the docking accuracy of the detection plug 9 and the connecting plug 81. Finally, under the action of the first spring 41, the detection plug 9 and the connecting plug 81 are docked, and then the detection of the rotor 8 can be started.

[0071] Refer to Figure 1 , Figure 2 , Figure 10 , Figures 17 - 19 , after the detection of the rotor 8 is completed. The motor 21 drives the first rotating rod 22 to reverse. The reverse rotation of the first rotating rod 22 drives the mounting seat 13 to move away from the rotor 8 through the cooperation of the second gear 23 and the first rack 24. During the process of the mounting seat 13 moving away from the rotor 8, the first rubber wheel 45 will contact the first friction rail 46. After the two come into contact, the first rubber wheel 45 will idle with the outer ring of the first one-way bearing 44. During the process of the mounting seat 13 moving away from the rotor 8, under the pulling force of the second spring 65, the guide rod 62 and the friction block 64 will also move into the first friction rail 46 and move back to their original positions. During the reverse rotation of the first rotating rod 22, it will drive the first gear 14 to rotate forward through the third gear 31, so that the pressing block 15 moves away from the limiting block 16, canceling the pressing limit of the pressing block 15 on the connecting plug 81.

[0072] Refer to Figure 1 , Figure 2 , Figure 10 , Figures 17 - 19, during the process that the mounting seat 13 moves away from the rotor 8, the first rubber wheel 45 will reverse and drive the outer ring of the first one-way bearing 44 to rotate idly in the reverse direction. Meanwhile, during the process that the mounting seat 13 moves away from the rotor 8, first, it is detected that the detection plug 9 moves away from the connection plug 81. Then, the second friction rail 534 will move to contact the second rubber wheel 533 and drive the second rubber wheel 533 to reverse. The reverse rotation of the second rubber wheel 533 will drive the second rotating rod 531 to reverse through the second one-way bearing 532. When the second rotating rod 531 reverses, it will drive the sliding rod 18 to slide away from the second sliding groove 17 through the cooperation of the fourth gear 535 and the second rack 536. When the sliding rod 18 moves away from the second sliding groove 17, it will drive the abutting plate 12 to move away from the first gear 14. When the abutting plate 12 moves away from the first gear 14, it will push the rotor 8 to move, and finally push the rotor 8 out of the fixing rod 11, completing the automatic blanking of the rotor 8.

[0073] Refer to Figure 1 , Figure 2 , Figure 10 , Figures 17 - 19 , subsequently, the second friction rail 534 will move away from the second rubber wheel 533. Once the two are separated, the third spring 52 will push the connecting block 51 to move into the second sliding groove 17 and cause the sliding rod 18 to move into the second sliding groove 17. When the sliding rod 18 moves into the second sliding groove 17, it will drive the abutting plate 12 to move back to its original position. During the process that the sliding rod 18 moves back to its original position, it will drive the second rotating rod 531 to reverse and return to its original position through the cooperation of the fourth gear 535 and the second rack 536.

[0074] Refer to Figure 1 , Figure 2 , Figure 10 , Figures 17 - 19 , during the process that the detected rotor 8 is pushed out of the fixing rod 11, the technician can hold the next rotor 8 to be detected. After the detected rotor 8 is pushed out of the fixing rod 11, the technician can immediately sleuth the new rotor 8 on the fixing rod 11 for detection. Then, during the detection of the next rotor 8, the detected rotors 8 can be uniformly placed and collected.

[0075] Of course, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by this application.
