Technical Field

[0001] The invention relates to the field of detection equipment, in particular to an improved type of energized testing equipment for a shielded pump. Background Art

[0002] During the production process of the canned motor pump, it is necessary to use power-on test equipment to conduct power-on test on the rotor of the canned motor pump.

[0003] An improved canned motor pump has a rotor as shown in FIG. Fig. 20 As shown, a connection plug is provided on the rotor. When the rotor of the pump body is subjected to an electrical test, the technician needs to first sleeve the rotor onto the fixing rod of the electrical test equipment, and then insert the detection plug of the electrical test equipment into the connection plug, so that the rotor is connected to the electrical test equipment, and then the electrical test equipment can detect the electrical performance of the rotor.

[0004] The detection efficiency of the manual docking plug method is low. When inspecting a rotor, technicians spend most of their time plugging and unplugging 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 of the power-on test equipment and the connection plug. Summary of the invention

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

[0006] The improved canned motor pump power-on test equipment provided in this application adopts the following technical solution: An improved canned motor pump power-on test device comprises a machine body, a fixed rod arranged on the machine body for a rotor to be sleeved, a back plate arranged on the fixed rod, and a detection plug arranged on the machine body, wherein a mounting seat is slidably connected to the machine body along the X-axis direction, the detection plug is arranged on the mounting seat, and the detection plug is located between the mounting seat and the fixed rod, a first control mechanism is arranged on the machine body, and the first control mechanism is used to control the mounting seat to slide so that the mounting seat moves close to the fixed rod or moves away from the fixed rod; a first gear is rotatably connected to the fixed rod, and a first gear is arranged on the first gear There is a pressing block; a limit block is provided on the pressing plate, and the limit 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 the pressing plate, the connecting plug is located on the rotation path of the pressing block; a second control mechanism for controlling the rotation of the first gear is provided on the machine body, and the second control mechanism controls the reverse rotation of the first gear to drive the pressing block to move close to the limit block and press the connecting plug against the limit block, and when the connecting plug is pressed against the limit block by the pressing block, the connecting plug is opposite to the detection plug and is located on the movement path of the detection plug.

[0007] By adopting the above technical solution, the technician sets the rotor on the fixed rod and makes the connecting plug located between the limit block and the pressure block. Then the second drive mechanism drives the first gear to reverse so that the pressure block rotates and pushes the connecting plug to rotate. Finally, the pressure block presses the connecting plug against the limit block to complete the alignment of the connecting plug and the detection plug. There is no need to manually adjust the alignment, which reduces the requirements for the rotor setting and facilitates the technicians to set the rotor. Then the first drive mechanism drives the mounting seat to slide so that the detection plug moves close to the connecting plug and finally the two are plugged in, and the detection of the rotor can be started. After the detection is completed, the first drive mechanism drives the mounting seat to slide and reset to separate the detection plug from the connecting plug. At the same time, the second drive mechanism drives the first gear to rotate to cancel the pressure of the pressure block on the connecting plug, and the rotor can be removed from the fixed rod.

[0008] Preferably, the first control mechanism includes a motor arranged on the machine body, a first rotating rod arranged on the output shaft of the motor, a second gear sleeved on the first rotating rod, and a first rack arranged on the mounting seat, the second gear is meshed with the first rack, and when the first rotating rod rotates forward, the mounting seat is driven to move closer to the fixed rod through the cooperation of the second gear and the first rack; when the first rotating rod is reversed, the mounting seat is driven to move away from the fixed rod through the cooperation of the second gear and the first rack.

[0009] By adopting the above technical solution, the movement of the mounting seat can be controlled by the motor driving the first rotating rod to rotate forward and reverse, thereby controlling the plugging and unplugging of the connecting plug and the detecting plug.

[0010] Preferably, the second control mechanism includes a third gear provided on the first rotating rod, the third gear meshing with the first gear, and when the first rotating rod rotates forward, the third gear drives the first gear to rotate reversely; when the first rotating rod rotates reversely, the third gear drives the first gear to rotate forwardly.

[0011] By adopting the above technical solution, when the first rotating rod rotates forward or reversely, the third gear can drive the first gear to rotate forward or reversely.

[0012] Preferably, a first slide groove is provided on the mounting seat, a T-block is slidably connected in the first slide groove along the X-axis direction, the smaller end of the T-block extends out of the mounting seat, the detection plug is located between the mounting seat and the fixed rod, and a third control mechanism is also provided on the body, and the third control mechanism is used to control the movement of the T-block.

[0013] By adopting the above technical solution, when the mounting seat moves toward the rotor, the third control mechanism drives the T-block to move into the first slide slot, allowing the detection plug to move closer to the mounting seat, so that the detection plug will not dock with the connection plug during the movement of the mounting seat, preventing the two from colliding with each other. After the pressing block presses the connection plug against the limit block and the mounting seat stops moving, the third driving mechanism drives the T-block to move out of the first slide slot, thereby driving the detection plug to move toward the connection plug and finally allowing the detection plug and the connection plug to be plugged into each other.

[0014] Preferably, the third control mechanism includes a first spring arranged in the first slide groove, a pull rod rotatably connected to the mounting seat, a pull rope arranged 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 arranged on the machine body and in contact with the first rubber wheel; the first spring is located on the side of the T-block away from the detection plug, the first spring always drives the T-block to move toward the fixed rod, and when there is no external force, the first spring presses the T-block against the side wall of the first slide groove close to the fixed rod; the One end of the pull rope away from the pull rod extends into the first slide groove and is connected to the T-block, and when the pull rod rotates, the pull rope is wound to drive the T-block to move into the first slide groove and compress the first spring; when the mounting seat moves close to the fixed rod, the first rubber wheel rubs against the first friction rail and rotates forward, and the first rubber wheel rotates forward and drives the outer ring of the first one-way bearing to rotate forward; the outer ring of the first one-way bearing rotates forward, driving the inner ring of the first one-way bearing and the pull rod to rotate forward; when the mounting seat moves to the position closest to the fixed rod, the first rubber wheel moves to disengage from the first friction rail.

[0015] By adopting the above technical solution, when the mounting seat moves close to the fixed rod, the first rubber wheel will rotate forward under the action of friction and will rotate forward with the inner and outer rings of the first one-way bearing and the pull rod. The pull rod rotates and winds the pull rope to make the T-block slide into the first slide groove and squeeze the first spring, so that the detection plug moves close to the mounting seat, so that the detection plug will not dock with the connection plug during the movement of the mounting seat. After the mounting seat stops moving close to the fixed rod, the first friction rail will be separated from the first rubber wheel, and the first spring will rebound and drive the T-block to move close to the fixed rod so that the detection plug will dock with the connection plug.

[0016] Preferably, a mounting groove is provided in the first friction rail, a guide rod is slidably connected in the mounting groove along the X-axis direction, an avoidance groove is provided on the side wall of the mounting groove, a friction block is provided on the guide rod, the friction block extends out of the first friction rail through the avoidance groove, and the friction block is located on the movement path of the pull rod; a second spring is provided in the mounting 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, and the elastic force of the first spring is greater than the elastic force of the second spring; when the pull rod moves close to the fixed rod, it will conflict with the friction block and push the friction block and the guide rod to move close to the fixed rod, so that the second spring is stretched under force.

[0017] By adopting the above technical solution, when the mounting seat slides close to the fixed rod, the pull rod will contact with the friction block and push the friction block and the guide rod to move close to the fixed rod. Once the first friction rail and the first rubber wheel are separated, the first spring will drive the pull rod to rotate, and the rotation of the pull rod will rotate with the first one-way bearing and the first friction wheel. However, under the action of the second spring, the friction block will always press against the pull rod, so that friction is generated 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 instantly and driving the T-block to move close to the fixed rod. Finally, the purpose of extending 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 on the limit block, thereby improving the accuracy of the docking of the detection plug and the connection plug. After the equipment is used for a period of time, the connection between the friction block and the pull rod is worn, but under the action of the second spring, it can always ensure that the friction block and the pull rod are in contact when the pull rod rotates, thereby ensuring that the friction block always has a deceleration effect on the pull rod when the pull rod rotates.

[0018] Preferably, a second slide groove is provided on the machine body, a slide rod is slidably connected in the second slide groove along the Y-axis direction, the push plate is slidably connected to the fixed rod along the Y-axis direction, one end of the slide rod extends out of the second slide groove and is connected to the push plate, and a fourth control mechanism for controlling the sliding of the slide rod is also provided on the machine body. After the rotor detection is completed, the fourth control mechanism controls the sliding of the slide rod to make the push plate move to push the rotor out of the fixed rod.

[0019] 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 push plate pushes the rotor to move, and finally the push plate pushes the rotor out of the fixed rod to complete the automatic unloading of the rotor.

[0020] Preferably, the fourth control mechanism includes a connecting block arranged on the sliding rod, a third spring arranged in the second sliding groove, and a control component for driving the sliding rod to move out of the second sliding groove, the third spring is sleeved on the sliding rod, the third spring is located on the side of the connecting block close to the abutment plate, the elastic force of the third spring acts on the connecting block, the first gear is located between the abutment plate and the connecting block, the third spring always drives the connecting block to move away from the first gear, and the control component controls the sliding rod to move away from the second sliding groove so that the abutment plate moves away from the first gear and pushes the rotor out of the fixed rod.

[0021] By adopting the above technical solution, after the rotor detection is completed, the control component controls the sliding rod and the connecting block to move away from the second sliding groove so that the push plate pushes the detected rotor out of the fixed rod, and when the connecting block moves away from the second sliding groove, it squeezes the third spring so that the third spring is compressed. After the rotor is pushed out of the fixed rod, the control component cancels the force applied to the sliding rod, and the third spring rebounds to drive the connecting block and the sliding rod to reset, thereby leading the push plate to move and reset.

[0022] Preferably, the control component comprises a second rotating rod rotatably connected to the machine body, a second one-way bearing arranged on the second rotating rod, a second rubber wheel sleeved on the outer ring of the second one-way bearing, a second friction rail arranged on the mounting seat and used to contact the second rubber wheel, a fourth gear arranged on the second rotating rod, and a second rack arranged on the sliding rod and meshed 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 when the outer ring rotates forward; the second friction rail does not contact the second rubber wheel in an initial state; when the mounting seat moves toward the fixed 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; when the mounting seat moves away from the fixed 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 reverse; before the second friction rail drives the second rubber wheel to reverse, the detection plug has been separated from the connection plug; when the second rotating rod reverses, the fourth gear and the second rack cooperate to drive the sliding rod and the connecting block to move out of the second slide groove.

[0023] By adopting the above technical solution, when the mounting seat slides away from the fixed rod, the plug is first detected to be disengaged from the connection plug, and then the second friction rail moves to contact with the second rubber wheel and drives the second rubber wheel to reverse. The second rubber wheel reverses and drives the second rotating rod to reverse through the second one-way bearing. When the second rotating rod reverses, the fourth gear and the second rack drive the sliding rod to slide away from the second slide slot. When the sliding rod moves away from the second slide slot, it drives the push plate to move away from the first gear. When the push plate moves away from the first gear, it pushes the rotor to move, and finally pushes the rotor out of the fixed rod to complete the automatic unloading of the rotor. When the mounting seat moves away from the fixed rod, the second friction rail moves to disengage from the second rubber wheel. Once the two are disengaged, the third spring pushes the connecting block to move into the second slide slot and causes the sliding rod to move into the second slide slot. When the sliding rod moves into the second slide slot, it moves the push plate to reset.

[0024] The technical effects of the present invention are mainly reflected in the following aspects: 1. The present invention can automatically complete the automatic docking of the connection plug and the detection plug; 2. The present invention improves the docking accuracy between the connection plug and the detection plug by delaying the action of the detection plug; 3. The present invention can automatically push the rotor out of the fixing rod after the detection is completed, so as to facilitate the detection of the next rotor. BRIEF DESCRIPTION OF THE DRAWINGS

When the first rotating rod 22 rotates forward, the second gear 23 and the first rack 24 cooperate to drive the mounting seat 13 to move closer to the fixed rod 11; when the first rotating rod 22 rotates backward, the second gear 23 and the first rack 24 cooperate to drive the mounting seat 13 to move away from the fixed rod 11.

[0050] Reference Figure 1-Figure 4The fixing rod 11 is rotatably connected with a first gear 14, and a pressing block 15 is fixed to the first gear 14. A stop block 16 is provided on the pressing plate 12, and the stop 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.

[0051] Reference Figure 1-Figure 4 A second control mechanism 3 for controlling the rotation of the first gear 14 is provided on the body 1. The second control mechanism 3 controls the first gear 14 to reverse to drive the pressing block 15 to move close to the limit block 16 and press the connecting plug 81 against the limit block 16. When the connecting plug 81 is pressed against the limit block 16 by the pressing block 15, the connecting plug 81 is opposite to the detection plug 9 and is located on the movement path of the detection plug 9.

[0052] Reference Figure 1-Figure 4 The second control mechanism 3 includes a third gear 31 fixed on the first rotating rod 22, the third gear 31 is meshed with the first gear 14, and when the first rotating rod 22 rotates forward, the first gear 14 is driven to rotate reversely 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.

[0053] Reference Figure 1 and Figure 4 A first slide groove 131 is provided on the mounting seat 13, and a T-block 132 is slidably connected in the first slide groove 131 along the X-axis direction. The smaller end of the T-block 132 extends out of the mounting seat 13, and the detection plug 9 is installed on the end of the T-block 132 extending out of the mounting seat 13. The detection plug 9 is located between the mounting seat 13 and the fixing rod 11.

[0054] Reference Figure 1 , Figure 2 , Figure 4 , Fig.12 and Fig.13 The machine body 1 is also provided with a third control mechanism 4, which is used to control the movement of the T-block 132. The third control mechanism 4 includes a first spring 41 arranged in the first slide groove 131, a pull rod 42 rotatably connected to the mounting seat 13, a pull rope 43 with one end fixed to 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 to the machine body 1 and in conflict with the first rubber wheel 45.

[0055] Reference Figure 1 , Figure 2 , Figure 4 , Fig.12 and Fig.13, the first spring 41 is located on the side of the T-block 132 away from the detection plug 9. The first spring 41 always drives the T-block 132 to move toward the fixed rod 11. When there is no external force, the first spring 41 presses the T-block 132 against the side wall of the first slide groove 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. The end of the pull rope 43 away from the pull rod 42 extends into the first slide groove 131 and is connected to the T-block 132. When the pull rod 42 rotates, the pull rope 43 is wound to drive the T-block 132 to move into the first slide groove 131 and compress the first spring 41. When the mounting seat 13 moves close to the fixed rod 11, the first rubber wheel 45 rotates 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 to separate from the first friction rail 46.

[0056] Reference Figure 5-Figure 7 The first friction rail 46 is provided with a mounting groove 61, in which a guide rod 62 is slidably connected along the X-axis direction, and one end of the guide rod 62 close to the fixed rod 11 extends out of the mounting groove 61; an avoidance groove 63 is provided on the side wall of the mounting groove 61, and 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.

When the pull rod 42 moves close to the fixed rod 11, it will conflict with the friction block 64 and push the friction block 64 and the guide rod 62 to move close to the fixed rod 11 and cause the second spring 65 to be stretched.

[0057] Reference Figure 1 , Figure 2 , Figure 8 and Fig. 9 The support plate 12 is slidably connected to the fixed rod 11 along the Y-axis direction. A second slide groove 17 is provided on the body 1, and a sliding rod 18 is slidably connected to the second slide groove 17 along the Y-axis direction. One end of the sliding rod 18 extends out of the second slide groove 17 and is fixedly connected to the support plate 12.

[0058] Reference Figure 1 , Figure 2 , Figure 8-Figure 10The body 1 is also provided with a fourth control mechanism 5 for controlling the sliding movement of the sliding rod 18. After the detection of the rotor 8 is completed, the fourth control mechanism 5 controls the sliding movement of the sliding rod 18 to make the abutment plate 12 move away from the first gear 14 and push the rotor 8 out of the fixed rod 11. The fourth control mechanism 5 includes a connecting block 51 fixed on the sliding rod 18 and a third spring 52 arranged in the second slide groove 17. The third spring 52 is sleeved on the sliding rod 18, and the third spring 52 is located on the side of the connecting block 51 close to the abutment 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 abutment plate 12. When there is no external force, the third spring 52 presses the connecting block 51 against the side wall of the third slide groove away from the abutment plate 12.

[0059] Reference Figure 1 , Figure 2 , Figure 8-Figure 10 The fourth control mechanism 5 also includes a control assembly 53 for driving the sliding rod 18 to move out of the second slide slot 17. The control assembly 53 controls the sliding rod 18 to move away from the second slide slot 17 so that the stop plate 12 moves away from the first gear 14. The control assembly 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 conflict with 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 meshed 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.

[0060] Reference Figure 2 , Fig.14 , Fig.17 , Fig.18 , the outer ring of the first one-way bearing 44 rotates forward without driving the inner ring of the first one-way bearing 44 to rotate. In the initial state, the second friction rail 534 does not contact the second rubber wheel 533; when the mounting seat 13 moves closer to the fixed 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. When the mounting seat 13 moves away from the fixed 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 reversely. Before the second friction rail 534 drives the second rubber wheel 533 to rotate reversely, the detection plug 9 has been separated from the connection plug 81. The outer ring of the second one-way bearing 532 rotates reversely, which drives the inner ring of the second one-way bearing 532 and the second rotating rod 531 to rotate reversely. When the second rotating rod 531 rotates reversely, the sliding rod 18 and the connecting block 51 move out of the second sliding groove 17 through the cooperation of the fourth gear 535 and the second rack 536.

[0061] The specific testing steps for this application power-on test equipment are as follows: Reference Figure 1 , Figure 2 , Figure 11-13 , the technician sets the rotor 8 on the fixed rod 11, and makes the connecting plug 81 located between the limit block 16 and the pressure block 15, and then the motor 21 starts and drives the first rotating rod 22 to rotate forward. When the first rotating rod 22 rotates forward, it drives 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 movement of the mounting seat 13 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 drives 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 is wound to make the T-block 132 slide into the first slide groove 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 dock with the connecting plug 81 during the movement of the mounting seat 13.

[0062] Reference Figure 1 , Figure 2 , Figure 14-16 When the mounting seat 13 slides close to the rotor 8, the pull rod 42 contacts the friction block 64 and pushes the friction block 64 and the guide rod 62 to move close to the fixed rod 11, so that the first friction track 46 moves between the guide rod 62 and the friction block 64. At the same time, when the mounting seat 13 slides close to the rotor 8, the second friction track 534 contacts the second rubber wheel 533 and drives the second rubber wheel 533 to rotate forward, and the second rubber wheel 533 rotates forward to drive the outer ring of the second one-way bearing 532 to rotate forward.

[0063] Reference Figure 1 , Figure 2 , Fig.11 , Fig.14 During the forward rotation of the first rotating rod 22, the first rotating rod 22 drives the first gear 14 to reverse through the third gear 31, and the reverse rotation of the first gear 14 causes the pressing block 15 to rotate and push the connecting plug 81 to rotate. Finally, the reverse rotation of the first gear 14 causes the pressing block 15 to rotate and push the connecting plug 81 to rotate, and finally the pressing block 15 presses the connecting plug 81 against the limit block 16.

[0064] Reference Figure 1 , Figure 2 , Figure 11-Figure 16 When the pressing block 15 moves to press the connection plug 81 against the limit block 16, the first rotating rod 22 stops rotating, and the mounting seat 13 also stops moving. After the mounting seat 13 stops moving, the first friction rail 46 is separated from the first rubber wheel 45, and the first spring 41 rebounds and drives the T-shaped block 132 and the detection plug 9 to move close to the connection plug 81 so that the detection plug 9 and the connection plug 81 are connected.

[0065] Reference Figure 1 , Figure 2 , Figure 11-Figure 16 During the rebound process of the first spring 41, the first spring 41 will drive the pull rod 42 to rotate, but under the action of the second spring 65, the friction block 64 will always press against the pull rod 42, so that friction is generated between the friction block 64 and the pull rod 42, so that the pull rod 42 rotates at a constant speed, thereby preventing the first spring 41 from rebounding instantly and driving the T-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 connection plug 81 only after the pressing block 15 presses the connection plug 81 against the limit block 16, thereby improving the accuracy of the docking of the detection plug 9 and the connection plug 81. Finally, under the action of the first spring 41, the detection plug 9 and the connection plug 81 are docked, and then the detection of the rotor 8 can begin.

[0066] Reference Figure 1 , Figure 2 , Fig.10 , Figure 17-Figure 19 , after the rotor 8 detection is completed. The motor 21 drives the first rotating rod 22 to reverse, and the first rotating rod 22 reverses and 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 movement of the mounting seat 13 away from the rotor 8, the first rubber wheel 45 will contact the first friction rail 46. After the two contact, the first rubber wheel 45 will idle with the outer ring of the first one-way bearing 44. During the movement of the mounting seat 13 away from the rotor 8, under the action of the return 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 to reset. During the reversal of the first rotating rod 22, the third gear 31 will drive the first gear 14 to rotate forward, so that the pressing block 15 moves away from the limit block 16, and the pressing limit of the pressing block 15 on the connecting plug 81 is cancelled.

[0067] Reference Figure 1 , Figure 2 , Fig.10 , Figure 17-Figure 19, during the movement of the mounting seat 13 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 in the opposite direction. At the same time, during the movement of the mounting seat 13 away from the rotor 8, the detection plug 9 will first be disengaged from the connection plug 81, and 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 second rubber wheel 533 will reverse and 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 push plate 12 to move away from the first gear 14. When the push 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 unloading of the rotor 8.

[0068] Reference Figure 1 , Figure 2 , Fig.10 , Figure 17-Figure 19 , the second friction rail 534 will move to disengage from the second rubber wheel 533. Once the two are disengaged, the third spring 52 will push the connecting block 51 to move into the second slide groove 17 and make the sliding rod 18 move into the second slide groove 17. When the sliding rod 18 moves into the second slide groove 17, it will move and reset with the abutment plate 12. During the movement and reset of the sliding rod 18, the cooperation between the fourth gear 535 and the second rack 536 will drive the second rotating rod 531 to reverse and reset.

[0069] Reference Figure 1 , Figure 2 , Fig.10 , Figure 17-Figure 19 When the inspected rotor 8 is pushed out of the fixing rod 11, the technician can take the next rotor 8 to be inspected, and after the inspected rotor 8 is pushed out of the fixing rod 11, the technician can immediately put a new rotor 8 on the fixing rod 11 for inspection. Then, during the inspection of the next rotor 8, the inspected rotors 8 can be uniformly placed and collected.

[0070] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
