[0002] A mutual inductor generally refers to an instrument transformer, which is a special-purpose transformer with two main uses: one is to expand the range of AC electrical instruments, and the other is to isolate high voltage and high current and convert them into low voltage and low current as signals for relay protection, automatic devices and control circuits.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] For specific embodiment 1, please refer to Figure 1-17The present invention is an automatic testing and sorting machine for mutual inductors, comprising a conveying platform 1; an arc-shaped guide rail 2 is arranged on the conveying platform 1; the arc-shaped guide rail 2 is composed of a first arc-shaped plate 3, a second arc-shaped plate 4 and a third arc-shaped plate 5; a feeding trough 6 is provided on the side surface of the arc-shaped guide rail 2; the two sides of the second arc-shaped plate 4 are respectively connected with the first arc-shaped plate 3 and the third arc-shaped plate 5 by transition curves; the side surfaces of the first arc-shaped plate 3 and the third arc-shaped plate 5 are chamfered; the first arc-shaped plate 3, the second arc-shaped plate 4 and the third arc-shaped plate 5 are all cut from an elliptical plate in an elliptical shape; the first arc-shaped plate 3 and the second arc-shaped plate 4 correspond to elliptical plates of the same size; the third arc-shaped plate 5 corresponds to The diameter of the elliptical plate is smaller than the diameters of the elliptical plates corresponding to the first arc plate 3 and the second arc plate 4; a conveying disc 7 is slowly rotated on the conveying platform 1; two groups of T-shaped guide grooves 8 are symmetrically opened on the surface of the conveying disc 7; a number of mutual inductors 9 are arranged on the surface of the conveying platform 1; a socket 10 is fixed on the side of the mutual inductor 9; a T-shaped guide rail 11 slidingly matched with the T-shaped guide groove 8 is fixed on the bottom surface of the mutual inductor 9; the side surface of the mutual inductor 9 is adapted to the inner side surface of the first arc plate 3 and the outer side surface of the third arc plate 5; a connecting component 12 is arranged on the surface of the conveying disc 7; a detection component 13 is arranged on the surface of the arc guide rail 2; the connecting component 12 is connected to the detection component 13.

[0042] Specifically, two feed belt rollers 14 are symmetrically fixed between the two inner walls of the conveying platform 1; a feed conveyor belt 15 is transmitted between the two feed belt rollers 14; a first servo motor 16 is fixed to the side of the conveying platform 1; the output end of the first servo motor 16 is fixedly connected to a feed belt roller 14; a limit plate 17 is fixed to the side of the conveying platform 1; the limit plate 17 is fixedly connected to the side of the arc guide rail 2.

[0043] The working principle of this embodiment is: first turn on the first servo motor 16 to drive the feed belt roller 14 to rotate slowly, thereby driving the feed conveyor belt 15 to transmit, and then place the mutual inductor 9 on the surface of the feed conveyor belt 15, so that the mutual inductor 9 is transported to the inside of the feed trough 6 by the feed conveyor belt 15, and the T-shaped guide rail 11 slides along the T-shaped guide groove 8, driving the mutual inductor 9 to enter the inside of the arc guide rail 2.

[0044] Then slowly rotate the conveyor plate 7 to drive the mutual inductor 9 to slide along the inner wall of the first arc-shaped plate 3. During this process, the distance between the mutual inductor 9 and the connecting component 12 becomes closer and closer, so that the T-shaped guide rail 11 slides along the T-shaped guide groove 8 toward the connecting component 12, that is, the socket 10 and the connecting component 12 are closer and closer, and finally inserted into the connecting component 12. When the mutual inductor 9 reaches Figure 2 In the state shown, the conveyor plate 7 is stopped from rotating slowly, at which time the mutual inductor 9 is respectively fitted with the inner wall of the first arc plate 3 and the outer wall of the third arc plate 5, and then the detection component 13 is driven to detect whether the angular difference and waveform of the mutual inductor 9 are normal.

[0045] Then continue to slowly rotate the conveyor disc 7. At this time, the mutual inductor 9 slowly separates from the inner wall of the first arc-shaped plate 3 and slides along the outer wall of the third arc-shaped plate 5. During this process, the distance between the mutual inductor 9 and the connecting component 12 becomes farther and farther, so that the T-shaped guide rail 11 slides along the T-shaped guide groove 8 in the direction away from the connecting component 12, that is, the socket 10 is slowly separated from the connecting component 12 and finally separated from the inside of the arc-shaped guide rail 2. At this time, the T-shaped guide rail 11 is separated from the T-shaped guide groove 8, and the mutual inductor 9 is continued to be conveyed by the feed conveyor belt 15. At the same time, the next mutual inductor 9 that needs to be detected just enters the inside of the arc-shaped guide rail 2 from the feed groove 6. Figure 7 The state shown in the figure, then take away the mutual inductor 9, keep the normal mutual inductor 9, repair the faulty mutual inductor 9 in time, and repeat the above operation to detect the next mutual inductor 9.

[0046] In this embodiment, the arc guide rail 2 is assembled from a first arc plate 3, a second arc plate 4 and a third arc plate 5, so that the running trajectory of the mutual inductor 9 from feeding to detection and finally to discharging is to first slowly approach the connecting component 12 and then slowly move away from the connecting component 12, and the diameter of the elliptical plate corresponding to the third arc plate 5 is smaller than the diameters of the elliptical plates corresponding to the first arc plate 3 and the second arc plate 4, so that the mutual inductor 9 can be located inside the arc guide rail 2 during feeding and receive an inward thrust, and can be located outside the arc guide rail 2 during discharging and receive an outward thrust, thereby realizing the automatic connection and separation of the socket 10 of the mutual inductor 9 and the connecting component 12.

[0047] For specific embodiment 2, please refer to Figure 1-17 On the basis of the specific embodiment 1, L-shaped connecting plates 18 are fixed on the surface of the conveyor table 1 near the two feed belt rollers 14; a feed U-shaped plate 19 and a discharge U-shaped plate 20 are fixed on the sides of the two L-shaped connecting plates 18; two guide plates 21 are symmetrically fixed on the sides of the feed U-shaped plate 19; an L-shaped mounting plate 22 is fixed on the surface of the feed U-shaped plate 19; an L-shaped connecting shaft 23 is fixed on the inner top surface of the L-shaped mounting plate 22; a limiting ring 24 is fixed on the end of the L-shaped connecting shaft 23; and an annular limiting groove 25 is provided on the inner wall of the limiting ring 24.

[0048] Specifically, the connecting component 12 includes two terminal blocks 26 symmetrically fixed on the surface of the conveying disk 7; a plug 27 that is plugged into the socket 10 is fixed on the side of the terminal block 26; two U-shaped fixing plates 28 are symmetrically fixed on the surface of the conveying disk 7; a positioning plate 29 is fixed between the surfaces of the two U-shaped fixing plates 28; the side and top surfaces of the terminal blocks 26 are respectively close to the side surfaces of the U-shaped fixing plates 28 and the bottom surfaces of the positioning plates 29; a linkage shaft 30 that is compatible with the inner wall of the limit ring 24 is fixed on the surface of the positioning plate 29; an annular limit rail 31 that is compatible with the inner wall of the annular limit groove 25 is fixed on the side surface of the linkage shaft 30.

[0049] Furthermore, a first bevel gear 32 is fixed to the side of a feed belt roller 14; a second bevel gear 33 meshing with the first bevel gear 32 is slowly rotated and arranged on the surface of the conveying platform 1; a connecting column 34 is fixed to the surface of the second bevel gear 33; a first pulley 35 is fixed to the top of the connecting column 34; a second pulley 36 is slowly rotated and arranged through the surface of the L-shaped mounting plate 22; a first belt 37 is arranged for transmission between the first pulley 35 and the second pulley 36; a first electric telescopic rod 38 is fixed to the bottom surface of the second pulley 36; and a first friction wheel 39 is fixed to the telescopic end of the first electric telescopic rod 38.

[0050] Furthermore, the detection component 13 includes a limit column 40 fixed on the surface of the first curved plate 3 and a reciprocating screw 41 slowly rotating on the surface of the third curved plate 5; a detection plate 42 is slidably arranged on the side surface of the limit column 40; a sliding hole 43 is opened through the surface of the detection plate 42; a sliding block that slides with the thread groove of the reciprocating screw 41 is arranged on the inner wall of the sliding hole 43; a third pulley 44 is fixed on the side surface of the reciprocating screw 41 near the bottom end; a fourth pulley 45 is fixed on the top of the linkage shaft 30; a second belt 46 is arranged for transmission between the third pulley 44 and the fourth pulley 45; a second friction wheel 47 is fixed on the surface of the fourth pulley 45.

[0051] Furthermore, a current transformer calibrator 48 is fixed on the surface of the L-shaped mounting plate 22; a first detection head 49 and a second detection head 50 are fixed on the detection plate 42; and electric wires are connected between the current transformer calibrator 48 and the first detection head 49 and the second detection head 50, respectively.

[0052] The working principle of this embodiment is as follows: an electromagnet is provided on the surface of the third arc-shaped plate 5, and a permanent magnet is provided on the bottom surface of the fourth pulley 45. In the initial state, the electromagnet is turned on, the electromagnet and the permanent magnet are attracted by opposite charges, and then the fourth pulley 45 is fixed, and the T-shaped guide groove 8 is aligned with the feed U-shaped plate 19, so that the T-shaped guide rail 11 on the mutual inductor 9 can slide smoothly into the T-shaped guide groove 8.

[0053] First, the first servo motor 16 drives the feed belt roller 14 to rotate slowly, and then the feed conveyor belt 15 is driven to work. The slow rotation of the feed belt roller 14 drives the first bevel gear 32 to rotate slowly, and then drives the second bevel gear 33 to rotate slowly, and then drives the connecting column 34 to rotate slowly, and then drives the first pulley 35 to rotate slowly, and then drives the second pulley 36 to rotate slowly through the first belt 37, and then drives the first electric telescopic rod 38 and the first friction wheel 39 to rotate slowly.

[0054] Then, the mutual inductors 9 are placed at equal intervals on the surface of the feed conveyor belt 15, and then the mutual inductors 9 are driven by the feed conveyor belt 15 to approach the arc guide rail 2, and then the mutual inductors 9 first slowly approach the feed U-shaped plate 19 along the two guide plates 21, and then the T-shaped guide rail 11 slides along the T-shaped guide groove 8 into the interior of the arc guide rail 2.

[0055] Then, the telescopic end of the first electric telescopic rod 38 is driven to move downward, driving the first friction wheel 39 to move downward, and finally against the surface of the second friction wheel 47, and at the same time, the electromagnet is closed, releasing the adsorption of the permanent magnet, and then releasing the fixation of the fourth pulley 45, thereby driving the fourth pulley 45 and the linkage shaft 30 to rotate slowly, thereby driving the positioning plate 29 and the U-shaped fixing plate 28 to rotate slowly, thereby driving the conveying disc 7 and the terminal block 26 on its surface to rotate slowly, and then the conveying disc 7 drives the mutual inductor 9 to slide along the inner wall of the first arc plate 3. During this process, the distance between the mutual inductor 9 and the corresponding terminal block 26 becomes closer and closer, so that the T-shaped guide rail 11 slides along the T-shaped guide groove 8 toward the direction close to the terminal block 26, that is, the socket 10 and the plug 27 are closer and closer, and finally inserted into the plug 27. During the slow rotation of the conveying disc 7, the annular limit rail 31 rotates slowly along the annular limit groove 25 on the limit ring 24, so that the conveying disc 7 and all components on the conveying disc 7 are supported.

[0056] When transformer 9 arrives Figure 2 In the state shown, the electromagnet is turned on to attract the permanent magnet, and at the same time, the telescopic end of the first electric telescopic rod 38 is driven to retract. At this time, the first friction wheel 39 is separated from the second friction wheel 47. At this time, the second friction wheel 47 cannot rotate slowly, and then the conveying plate 7 stops rotating slowly. At this time, the mutual inductor 9 stops moving and fits with the inner wall of the first arc plate 3 and the outer wall of the third arc plate 5 respectively.

[0057] In the process of the first friction wheel 39 and the second friction wheel 47 being fitted to drive the conveyor plate 7 to rotate slowly, the fourth pulley 45 rotates slowly and drives the third pulley 44 to rotate slowly through the second belt 46, thereby driving the reciprocating screw 41 to rotate slowly, thereby driving the slider to slide along the thread groove of the reciprocating screw 41, thereby driving the detection plate 42 to slide downward along the limit column 40, thereby driving the first detection head 49 and the second detection head 50 to move downward. When the mutual inductor 9 reaches Figure 2 In the state shown, the first detection head 49 and the second detection head 50 just contact the mutual inductor 9, at this time the first friction wheel 39 is separated from the second friction wheel 47, and then the fourth pulley 45 stops rotating slowly, and then the third pulley 44 stops rotating slowly, and then the reciprocating screw 41 stops rotating slowly, and then the detection component 13 and the mutual inductor 9 are both stationary, and at this time the mutual inductor 9 can be detected by the current transformer tester 48.

[0058] After the detection is completed, the telescopic end of the first electric telescopic rod 38 is driven to move downward, driving the first friction wheel 39 to move downward, and finally against the surface of the second friction wheel 47, and at the same time the electromagnet is closed, releasing the adsorption of the permanent magnet, and then releasing the fixation of the fourth pulley 45, thereby driving the fourth pulley 45 and the linkage shaft 30 to rotate slowly, thereby driving the positioning plate 29 and the U-shaped fixing plate 28 to rotate slowly, thereby driving the conveying disc 7 and the terminal block 26 on its surface to rotate slowly, at this time the mutual inductor 9 slowly separates from the inner wall of the first arc plate 3, and slides along the outer wall of the third arc plate 5, during this process the distance between the mutual inductor 9 and the terminal block 26 becomes farther and farther, causing the T-shaped guide rail 11 to slide along the T-shaped guide groove 8 in the direction away from the terminal block 26, that is, causing the socket 10 and the plug 27 to slowly separate, and finally detach from the inside of the arc guide rail 2 and enter the inside of the discharge U-shaped plate 20, and at the same time the next mutual inductor 9 to be detected just enters the inside of the arc guide rail 2 from the feed trough 6, that is, Figure 7 The state shown, at the same time, in this process, the third pulley 44 is driven by the fourth pulley 45 to rotate slowly in cooperation with the second belt 46, thereby driving the reciprocating screw 41 to rotate slowly, thereby driving the slider to slide along the threaded groove of the reciprocating screw 41, thereby driving the detection plate 42 to slide upward along the limit column 40, thereby driving the first detection head 49 and the second detection head 50 to move upward, so that the first detection head 49 and the second detection head 50 are separated from the mutual inductor 9, and then the feed conveyor belt 15 conveys the mutual inductor 9 along the discharging U-shaped plate 20, and then the mutual inductor 9 can be taken away, the normal mutual inductor 9 can be retained, and the faulty mutual inductor 9 can be repaired in time.

[0059] In this embodiment, by setting a connecting component 12 and a detection component 13, the connecting component 12 and the detection component 13 are connected together through a third pulley 44, a fourth pulley 45 and a second belt 46, and cooperate with the first electric telescopic rod 38, the first friction wheel 39, the second friction wheel 47, the permanent magnet and the electromagnet. When the first friction wheel 39 fits with the second friction wheel 47, the permanent magnet releases the adsorption of the electromagnet, and the conveying disc 7 and the reciprocating screw 41 rotate slowly and synchronously, thereby realizing the conveyance of the mutual inductor 9. When the first friction wheel 39 is separated from the second friction wheel 47, the permanent magnet adsorbs the electromagnet, and the feed conveying belt 15 keeps conveying the mutual inductor 9, but the conveying disc 7 stops rotating slowly. At this time, the static detection of the mutual inductor 9 is realized, thereby improving the detection efficiency.

[0060] For specific embodiment 3, please refer to Figure 1-17 On the basis of the specific embodiment 1 and the specific embodiment 2, a screening disc 51 is provided on the surface of the conveying platform 1 so as to rotate slowly; a screening slot 52 is provided on the surface of the screening disc 51; a second servo motor is fixed on the top surface of the conveying platform 1; and the output end of the second servo motor is fixedly connected to the screening disc 51.

[0061] Specifically, the other two ends of the feed belt roller 14 are fixed with a third bevel gear 53; two first belt rollers 54 and two second belt rollers 55 are symmetrically and slowly rotated on the side of the conveying platform 1 on both sides of the screening plate 51; a second conveying belt 56 is transmitted between the two first belt rollers 54; a third conveying belt 57 is transmitted between the two second belt rollers 55; and a fourth bevel gear 58 meshing with the third bevel gear 53 is fixed to the end of each first belt roller 54 and a second belt roller 55.

[0062] The working principle of this embodiment is as follows: the current transformer tester 48 is externally connected to a controller, an input end of the controller is electrically connected to the current transformer tester 48, and an output end of the controller is electrically connected to the second servo motor.

[0063] During the slow rotation of the feed belt roller 14, the two third bevel gears 53 are driven to rotate slowly, and then the corresponding fourth bevel gears 58 are driven to rotate slowly, and then the two fourth bevel gears 58 respectively drive the corresponding first belt roller 54 and second belt roller 55 to rotate slowly, and then drive the second conveyor belt 56 and the third conveyor belt 57 to rotate slowly.

[0064] When in Figure 7 In the state shown, the transformer 9 just enters the discharge U-shaped plate 20 and is transported into the screening slot 52 by the feed conveyor belt 15. The current transformer tester 48 sends the test result to the controller in advance. The controller controls the second servo motor to select the opposite slow rotation direction according to the normal or fault state of the transformer 9, such as Fig.14 As shown, when the mutual inductor 9 is normal, the second servo motor slowly rotates 90° clockwise to transfer the mutual inductor 9 to the second conveyor belt 56 for transportation. When the mutual inductor 9 fails, the second servo motor slowly rotates 90° counterclockwise to transfer the mutual inductor 9 to the third conveyor belt 57 for transportation, thereby realizing the sorting of the mutual inductor 9 after detection.

During this process, the distance between the mutual inductor (9) and the connecting component (12) becomes closer and closer, so that the T-shaped guide rail (11) slides along the T-shaped guide groove (8) in a direction close to the connecting component (12), so that the socket (10) and the connecting component (12) become closer and closer, and finally inserted into the connecting component (12).

At this time, the detection component (13) is driven to detect whether the angular difference and waveform of the mutual inductor (9) are normal; Then, the conveyor plate (7) continues to rotate slowly, at which time the mutual inductor (9) slowly separates from the inner wall of the first arc-shaped plate (3) and slides along the outer wall of the third arc-shaped plate (5). During this process, the distance between the mutual inductor (9) and the connecting component (12) becomes increasingly greater, causing the T-shaped guide rail (11) to slide along the T-shaped guide groove (8) in a direction away from the connecting component (12), so that the socket (10) and the connecting component (12) slowly separate and eventually detach from the inside of the arc-shaped guide rail (2). At this time, the T-shaped guide rail (11) separates from the T-shaped guide groove (8), and the mutual inductor (9) continues to be conveyed by the feed conveyor belt (15). At the same time, the next mutual inductor (9) to be tested just enters the inside of the arc-shaped guide rail (2) from the feed groove (6).
