Description

Technical Field

[0001] The present invention relates to the technical field of servo motor detection, and in particular to a servo motor circuit detection device and a detection method. Background Art

[0002] A servo motor is a motor that controls the operation of mechanical components in a servo system. It can control speed and position with high accuracy, and can convert voltage signals into torque and speed to drive the controlled object. When a servo motor leaves the factory, it is necessary to test the circuits, such as the power circuit, control circuit, protection circuit, and feedback circuit, to ensure product quality and to detect problems in the circuit in a timely manner.

DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0048] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0049] The circuit of the servo motor includes a power supply circuit, a control circuit, a feedback circuit and a protection circuit, wherein the power supply circuit measures the voltage value of the power input terminal to confirm whether it meets the rated voltage requirement of the motor, and checks whether the power supply line is firmly connected and whether there are faults such as short circuit and open circuit; the control circuit detects the control signal input terminal to confirm that the control signal can be received and processed normally; the feedback circuit detects the accuracy and stability of the encoder feedback signal, and confirms whether the communication between the feedback circuit and the control circuit is normal; the protection circuit simulates abnormal conditions to verify the reliability of the protection circuit; and in the prior art, there are technical problems of detection efficiency and safety in the detection process of the above-mentioned circuits.

[0050] Reference Figure 1-Figure 14A servo motor circuit detection device includes a transversely penetrating detection cabinet 1 and a detection terminal device 4 installed on the top of the detection cabinet 1. The detection cabinet 1 is provided with: a conveying frame 2, two U-shaped plates 5, a guide conveying plate 14, a straightening component 8, a synchronous reverse driving component 9 and a lifting connection component 11. The conveying frame 2 is installed in the detection cabinet 1, and a conveyor belt 3 for conveying a servo motor 10 to be detected is provided inside the conveying frame 2. The lifting connection component 11 is arranged on the inner top wall of the detection cabinet 1 and connected to the detection terminal device 4. The inner side of the bottom surface of the lifting connection component 11 is movably connected with a positive and negative electrode collection component 12, and the positive and negative electrode collection component 12 is connected to the detection terminal device 4 through the lifting connection component 11. The outer side of the bottom surface of the lifting connection component 11 is fixedly connected with a switching component 13 located below the positive and negative electrode collection component 12. The switching component 13 is adapted to the wiring terminal on the servo motor 10 to be detected and is movably connected to the positive and negative electrode collection component 12. The guide conveyor plate 14 is located above the conveyor belt 3. When conveying the servo motor 10 to be detected, the guide conveyor plate 14 guides the connecting wires of the servo motor 10 to be detected, keeps the wiring terminals above the guide conveyor plate 14, and keeps the bottom of the connecting wires vertical. By installing the straightening component 8, the guide conveyor plate 14, the lifting connection component 11, the positive and negative electrode collection component 12 and the adapter component 13, the straightening component 8 straightens the wiring terminals of the servo motor 10 to be detected and docks them with the adapter component 13, realizing efficient and convenient circuit detection of the servo motor 10 to be detected. There is no need to disassemble and assemble the servo motor, and there is no need for manual docking operations.

[0051] The straightening component 8 is described in detail below:

[0052] Reference Figure 1-Figure 5 There are two straightening components 8, which are respectively arranged on the outer side of each U-shaped plate 5 and move along the length direction of the U-shaped plate 5; so that the straightening components 8 can straighten the terminal blocks of the servo motor 10 to be detected from both sides of the conveyor belt 3.

[0053] Specifically, a horizontal transverse electric rail 503 is installed at the upper end of the side of the U-shaped plate 5 facing the conveyor belt 3, the straightening component 8 is installed on the transverse electric rail 503, and moves along the length direction of the transverse electric rail 503, the straightening component 8 includes a vertically arranged vertical translation guide rail 81, a first electric push rod 82 installed on the vertical translation guide rail 81, a clamping block 83 installed at the end of the first electric push rod 82, and a slide 84 installed at the lower end of the side of the vertical translation guide rail 81, the end of the first electric push rod 82 is connected to a slider installed on the vertical translation guide rail 81, the slide 84 is installed in a fitting manner on the transverse electric rail 503, and the clamping block 83 has a clamping groove on one side of the servo motor 10 to be detected.

[0054] Initially, the first electric push rod 82 of the straightening assembly 8 is retracted, and the height of the first electric push rod 82 is located above the servo motor 10 to be detected to avoid interference with the servo motor 10 to be detected on the conveyor belt 3. After being transported to the straightening position, the vertical translation guide rail 81 regulates the first electric push rod 82 to move downward. At the same time, the horizontal electric track 503 regulates the vertical translation guide rail 81 to move horizontally, and moves the clamping block 83 connected to the first electric push rod 82 to the bottom of the corresponding position of the connecting wire of the terminal of the servo motor 10 to be detected. Afterwards, the first electric push rod 82 extends, driving the clamping block 83 to move toward the wire under the terminal until the two clamping blocks 83 move into contact, clamping the wire in the cylindrical hole formed by the two clamping grooves, and the clamping block 83 is slidably arranged with the wire, so that the first electric push rod 82 moves upward, and the two clamping blocks 83 move upward along the wire until the two clamping blocks 83 move to the bottom of the terminal and are pressed against the terminal. At this time, the wire under the terminal is straightened to keep the terminal vertically stable, which is convenient for docking the adapter assembly 13.

[0055] In the process of the straightening assembly 8 straightening the terminal, in order to prevent the terminal connection wire from initially bending above the servo motor and affecting the straightening assembly 8 being clamped at the bottom of the terminal, a guide conveying plate 14 is provided. The guide conveying plate 14 is V-shaped and is provided from the feeding end of the detection cabinet 1 to a position close to the U-shaped plate 5. The end of the guide conveying plate 14 away from the feeding conveying position of the conveyor belt 3 is higher, so that the entire guide conveying plate 14 is inclined. A guide groove is provided in the middle of the guide conveying plate 14 for the connection wire of the servo motor 10 to be detected to pass through. The terminal is placed on the guide conveying plate 14, and the connection wire of the terminal passes through the guide groove. When the servo motor 10 to be detected is driven to move by the conveyor belt 3, the inclined guide conveyor plate 14 allows the terminal to rest on the guide conveyor plate 14 under the force of gravity and upward resistance, and the servo motor 10 to be detected continues to drive the terminal to move on the guide conveyor plate 14 until the servo motor 10 to be detected stops. During this process, the resistance encountered by the terminal gradually increases, so that when the movement stops and the detection begins, the moving distance of the terminal lags behind the moving distance of the servo motor 10 to be detected on the conveyor belt 3, thereby making the lower connecting wire in an inclined state, and the straightening component 8 can directly clamp the bottom of the terminal.

[0056] The lifting connection assembly 11 is described in detail below:

[0057] Reference Figure 1-Figure 11The lifting connection component 11 includes a connecting top plate 111 horizontally arranged at the upper end of the interior of the detection cabinet 1, a plurality of lifting cylinders 112 installed between the connecting top plate 111 and the top wall inside the detection cabinet 1, a second motor 113 installed on the top surface of the connecting top plate 111, and an annular conductive plate 114 rotatably installed on the bottom surface of the connecting top plate 111. The bottom surface of the connecting top plate 111 is provided with an annular bottom groove 11101 coaxially arranged with the output shaft of the second motor 113. The annular conductive plate 114 is rotatably installed in the annular bottom groove 11101. The bottom surface of the annular conductive plate 114 is connected to a plurality of conductive telescopic rods 115, and the bottom ends of the plurality of conductive telescopic rods 115 are fixedly installed on the positive and negative electrode collection components 12.

[0058] Furthermore, the lifting cylinder 112 controls the lifting of the connection top plate 111 at the upper end of the detection cabinet 1, and then controls the lifting of the positive and negative electrode collection components 12 and the adapter component 13 connected to the connection top plate 111, so that the adapter component 13 can be conveniently connected to the straightened terminal, and the second motor 113 is used to control the rotation of the positive and negative electrode collection components 12 under the connection top plate 111, so as to adjust the detection end device 4 according to different needs, and the annular conductive plate 114 and the conductive telescopic rod 115 are used to ensure that the positive and negative electrode collection components 12 are energized during the rotation of the second motor 113. At the same time, the telescopic design of the conductive telescopic rod 115 also facilitates the adaptation of the positive and negative electrode collection components 12 when they are lifted and lowered separately under the connection top plate 111.

[0059] The positive and negative electrode collection components 12 are described in detail below:

[0060] The positive and negative electrode collection assembly 12 includes a support plate 121 connected to a conductive telescopic rod 115, the support plate 121 is disc-shaped, and an annular upper rotating plate 122 is rotatably installed on the outer side of the top surface of the support plate 121. A rotating shaft 125 is fixedly connected to the center of the top surface of the support plate 121. The bottom surface of the support plate 121 is provided with a plurality of collection support plates respectively connected to the corresponding conductive telescopic rods 115. The bottom surface of each collection support plate is symmetrically provided with collection probes 124 connected to the positive and negative electrodes, that is, each collection support plate has two collection probes 124, one connected to the positive electrode and the other connected to the negative electrode, and the top surface of the annular upper rotating plate 122 is provided with a plurality of The second electric push rod 123 is fixed on the bottom surface of the top plate 111. When the second electric push rod 123 is extended or retracted, it can drive the support plate 121 to move under the connection top plate 111. The top surface of the rotating shaft 125 is provided with a prismatic hole adapted to the output shaft of the second motor 113, and the output shaft of the second motor 113 is inserted into the prismatic hole and can be extended or retracted to adapt to the lifting and lowering of the support plate 121. At the same time, the second motor 113 can drive the rotating shaft 125 to rotate through the prismatic hole, thereby driving the rotation of the support plate 121. When the support plate 121 rotates, the annular upper rotating plate 122 can ensure the stability of the second electric push rod 123.

[0061] The following is a detailed description of the adapter component 13:

[0062] The adapter assembly 13 includes an adapter base plate 131 coaxially arranged below the support plate 121, and a connecting rod 132 is fixedly connected to the top surface of the adapter base plate 131 near the edge, and the top end of the connecting rod 132 bypasses the support plate 121 and is fixed to the bottom surface of the connecting top plate 111 to ensure that it will not interfere with the rotation of the support plate 121, and a plug connector 133 adapted to the wiring terminals on the servo motor 10 to be detected is detachably installed on the bottom surface of the adapter base plate 131, and the detachable design of the plug connector 133 can be adapted according to the requirements of the wiring terminals on the servo motor 10 to be detected, and the top surface of the adapter base plate 131 is provided with a socket 134 adapted to the plug connector 133, and a socket positive electrode sheet 13401 and a socket negative electrode sheet 13402 in contact with the collection probe pin 124 are respectively provided on both sides of the top surface of the socket 134.

[0063] Specifically, during the docking detection process, the lifting cylinder 112 first controls the connection top plate 111, the support plate 121 and the adapter bottom plate 131 to rise and fall. When the adapter bottom plate 131 moves downward, the plug connector 133 is driven to move downward until the plug connector 133 is inserted into the wiring terminal of the servo motor 10 to be detected. After the plug connector 133 is inserted into the wiring terminal, the positive electrode piece 13401 and the negative electrode piece 13402 on the plug socket 134 are respectively connected to the positive and negative electrodes on the plug connector 133 to achieve positive and negative connection. Then the second motor 113 is started and controls the support plate 121 to rotate. The support plate 121 rotates so that the collection support plate of the circuit equipment to be detected rotates to be coaxial with the plug socket 134. At the same time, the two collection probes 124 on the collection support plate correspond to the positive electrode piece 13401 and the negative electrode piece 13402 of the plug socket. 2, then the second electric push rod 123 moves and extends, driving the support plate 121 to move downward until the two collection probes 124 contact the positive electrode sheet 13401 and the negative electrode sheet 13402 of the socket, completing the connection between the positive and negative electrodes of the detection end device 4 and the positive and negative electrodes of the servo motor 10 to be detected, and starting the circuit connection of a group of equipment. When the circuit detection of the group of equipment is completed, if it is necessary to replace another group of detection equipment, first start the second electric push rod 123 to shrink, and then start the second motor 113 to rotate again, so that the collection support plate connected to the other group of detection equipment rotates to be coaxial with the socket 134, and then the second electric push rod 123 extends downward again, driving the support plate 121 to move downward, and performing another circuit detection, and the cycle is repeated until all detection equipment are detected, and then the lifting cylinder 112 shrinks to separate the plug connector 133 from the wiring terminal.

[0064] Furthermore, when straightening the connection terminals of the servo motor 10 to be tested, in order to ensure the stability of the servo motor 10 to be tested, the servo motor 10 to be tested can also be positioned and clamped on the conveyor belt 3, and the clamped servo motor 10 to be tested can be straightened again, thereby facilitating the above docking work.

[0065] Specifically, refer to Figure 1-Figure 14 , two U-shaped plates 5 are fixed to the inner two side walls of the detection cabinet 1 in a mirror image, and a square cavity is formed between each U-shaped plate 5 and the inner wall of the adjacent detection cabinet 1, and an induction baffle 6 and a positioning and tightening assembly 7 passing through the U-shaped plate 5 are arranged in each square cavity. It should be noted that when positioning and clamping the servo motor 10 to be detected, it is first necessary to enable the two induction baffles 6 to block the servo motor 10 to be detected conveyed at the upper end of the conveyor belt 3, so the length of the two induction baffles 6 is greater than the width of the conveyor belt 3, and in order to enable the servo motor 10 to be detected to be quickly positioned and clamped after being blocked, and after the detection is completed, when no longer clamped, the servo motor can quickly pass through the induction baffle 6 from the conveyor belt 3 and continue to be transported backward, and the induction baffle 6 is synchronized with the positioning and tightening assembly 7 through the synchronous reverse drive assembly 9, so that when the induction baffle 6 blocks the servo motor 10 to be detected, the positioning and tightening assembly 7 is in a ready state, and when the positioning and tightening assembly 7 is needed to position and clamp the servo motor 10 to be detected, the induction baffle 6 is in a contracted and no longer blocking state.

[0066] Furthermore, the synchronous reverse drive component 9 is installed under the U-shaped plate 5 and passes through the conveying frame 2, and the synchronous reverse drive component 9 simultaneously drives the sensing baffle 6 and the positioning and tightening component 7 to move, and makes the sensing baffle 6 and the positioning and tightening component 7 on the same side move in opposite directions.

[0067] It should be noted that the conveyor belt 3 needs to be kept in a horizontal state, and support frames 101 are fixed at the openings at both ends of the detection cabinet 1. The conveyor frame 2 is mounted on the two support frames 101. The two ends of the top surface of the conveyor frame 2 are also provided with protective outer panels 201 extending to the top of the conveyor belt 3. The protective outer panels 201 can play a role in shielding and protection.

[0068] The induction baffle 6 is described in detail below:

[0069] A through slot 501 is formed at the side end of the U-shaped plate 5 facing the conveyor belt 3 for the sensing baffle 6 to pass through. The cross-section of the sensing baffle 6 is consistent with the through slot 501 and can stably slide in the through slot 501. The bottom of one end of the sensing baffle 6 located on the inner side of the U-shaped plate 5 is fixedly connected with a first slide plate 601 adapted to the synchronous reverse drive component 9, and a first pressure sensor is embedded in the side of the two sensing baffles 6 facing the servo motor 10 to be detected. When the servo motor 10 to be detected moves to contact the sensing baffle 6, it first touches the first pressure sensor. The first pressure sensor can transmit the pressure signal to the controller, thereby judging that the servo motor 10 to be detected is in contact with the sensing baffle 6 on the conveyor belt 3.

[0070] During the transportation of the servo motor 10 to be tested on the conveyor belt 3, there may be a problem of initial placement tilt, so the servo motor 10 to be tested needs to be kept horizontal during the test. The positioning and tightening assembly 7 is described in detail below:

[0071] The U-shaped plate 5 is provided with a through hole 502 for the positioning and tightening assembly 7 to pass through in the middle of the side facing the conveyor belt 3. The positioning and tightening assembly 7 includes a second slide plate 71 connected to the synchronous reverse drive assembly 9, a slide column 72 connected to the top of the second slide plate 71 and fitting through the through hole 502, and a buffer pressure plate 73 fixed to the end of the slide column 72. The buffer pressure plate 73 is embedded with a second pressure sensor in one side of the servo motor 10 to be detected. Through the setting of the second pressure sensor, when the slide column 72 drives the buffer pressure plate 73 to move to contact and clamp the side of the servo motor 10 to be detected, after the buffer pressure plate 73 performs buffering, according to the value of the preset second pressure sensor, the surface has been clamped to the servo motor 10 to be detected after reaching the value. With the cooperation of the induction baffle 6 and the positioning and tightening assembly 7, the servo motor 10 to be detected can be clamped and kept horizontal to facilitate detection.

[0072] The synchronous reverse drive component 9 is described in detail below:

[0073] The synchronous reverse drive assembly 9 includes a first double-ended lead screw 92 and a second double-ended lead screw 93 which are parallel to and penetrate the conveying frame 2 and are rotatably mounted on the inner wall of the detection cabinet 1. The same ends of the first double-ended lead screw 92 and the second double-ended lead screw 93 are respectively mounted with mutually meshing gears 94. The outer side surface of the detection cabinet 1 is mounted with a first motor 91 connected to the first double-ended lead screw 92. The first slide 601 is mounted on the first double-ended lead screw 92, and the second slide 71 is mounted on the second double-ended lead screw 93. The threads at both ends of the first double-ended lead screw 92 and the second double-ended lead screw 93 are opposite, so that when the first double-ended lead screw 92 and the second double-ended lead screw 93 rotate, the two first slides 601 move in opposite directions, the two second slides 71 move in opposite directions, and the first slide 601 and the second slide 71 on the same side move in opposite directions.

[0074] Furthermore, in order to realize the automation of the detection of the servo motor 10 to be detected on the conveyor belt 3, a display control panel 102 is installed on the outer side of the detection cabinet 1, and the display control panel 102 is electrically connected to the conveyor belt 3, the induction baffle 6, the positioning and tightening assembly 7, the straightening assembly 8, the synchronous reverse drive assembly 9, the lifting and connecting assembly 11 and the positive and negative pole collection assembly 12.

[0075] Working principle: When the servo motor 10 to be detected moves to contact the sensing baffle 6, the first pressure sensor in the sensing baffle 6 receives the pressure signal and transmits it to the controller. The display control panel 102 controls the conveyor belt 3 to stop conveying and starts the first motor 91 to rotate. The first motor 91 works to drive the first double-headed screw 92 to work. The first double-headed screw 92 works to make the two first slides 601 start to move away from the conveyor belt 3, and drive the two sensing baffles 6 to move from the conveyor belt 3 to the U-shaped plate 5 until the two sensing baffles 6 enter the U-shaped plate 5. At the same time, when the first double-headed screw 92 rotates, the second double-headed screw 93 rotates in the opposite direction under the engagement of the gear 94. The second double-headed screw 93 rotates to make the second slide 71 move toward the conveyor belt 3, and drive the slide column 72 and the buffer pressure plate 73 to move toward the servo motor to be detected. 10 moves in the opposite direction until the two buffer pressure plates 73 are pressed on the side of the servo motor 10 to be detected, clamping the servo motor 10 to be detected and keeping it horizontal, the U-shaped plate 5 leaves the servo motor 10 to be detected when the buffer pressure plate 73 is clamped to avoid obstruction when the servo motor 10 to be detected is horizontal, and when clamping, the first motor 91 is controlled to stop working, and when the detection is completed, the first motor 91 is controlled to reverse again. At the same time, the conveyor belt 3 is started to work, and when the first motor 91 reverses, the two buffer pressure plates 73 begin to move away from the conveyor belt 3, and the two induction baffles 6 begin to move towards each other, and when the buffer pressure plate 73 leaves the servo motor whose detection is completed, the servo motor continues to be transported backwards through the conveyor belt 3 until the two induction baffles 6 are close to each other and stick to each other, and the first motor 91 stops working again, and the next group of servo motors 10 to be detected are started to be positioned and clamped.

[0076] A method for detecting a servo motor circuit comprises the following steps:

[0077] S1, firstly, the servo motor 10 to be tested is horizontally placed on the conveyor belt 3, so that the connection terminals of the servo motor 10 to be tested are placed above the guide conveyor plate 14, and the servo motor 10 to be tested is conveyed forward by the conveyor belt 3;

[0078] S2, when the servo motor 10 to be detected moves to contact with the two inductive baffles 6, the controller suspends the operation of the conveyor belt 3, and controls the synchronous reverse drive component 9 to work, so that the inductive baffle 6 moves into the U-shaped plate 5, and at the same time, the positioning and tightening component 7 extends from the U-shaped plate 5 and tightens on both sides of the servo motor 10 to be detected;

[0079] S3, after positioning and clamping, the controller controls the two straightening components 8 to first clamp the wires below the terminal of the servo motor 10 to be tested, and then the two straightening components 8 move upward until they contact the bottom of the terminal and keep the terminal vertical;

[0080] S4, after the wiring terminal is straightened, the controller controls the lifting connection component 11 to move downward, and drives the positive and negative electrode collection components 12 and the adapter component 13 to move downward, so that the adapter component 13 is adapted to the wiring terminal;

[0081] S5, after the adapter is connected, the positive and negative pole collection components 12 start to connect with the adapter component 13 to perform circuit detection. After one group of equipment detection is completed, the lifting connection component 11 controls the positive and negative pole collection components 12 to rotate and continue the next group of equipment detection until the detection is completed.

[0082] Specifically, the controller is disposed in the display control panel 102, and a single chip microcomputer of the STM32 series may be selected.

[0083] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
