Description

Technical Field

[0001] This disclosure relates to the field of motor driver testing technology, and in particular to an intelligent testing device for motor drivers. Background Technology

[0002] A motor driver is an actuator that converts electrical pulses into angular displacement. When the driver receives a pulse signal, it drives the motor to rotate a fixed angle in a set direction. Its rotation proceeds step by step at fixed angles. The amount of angular displacement can be controlled by controlling the number of pulses, thus achieving accurate positioning. Simultaneously, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, thus achieving speed regulation and positioning.

[0003] During the production of motor drivers, the motors need to be tested to ensure their proper functioning. During testing, the motor drivers need to be connected to the circuit. In this process, the test motor's connection wires need to be plugged into the driver's connector. However, the connector positions differ for different driver models, requiring manual connection of the test motor to the driver, which results in lower testing efficiency for different driver models.

[0011] Optionally, the docking assembly further includes: a slide rail frame, a slide groove, a spring telescopic plate, and a crossbar. The top of the moving block is fixed with a spring telescopic plate, and the top of the spring telescopic plate is slidably inserted with a crossbar.

[0014] Optionally, the two ends of the movable frame are fixed with insert rods, and the two ends of the sliding frame are slidably sleeved on the surface of the insert rods.

[0015] Optionally, rotating frames are fixed on both sides of the entrance end of the test platform, and a recognition lens is rotatably mounted on the top of the rotating frames.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: This invention drives a screw to rotate via a drive motor. The screw seat and the screw thread engage to move the base plate along the convex strip, bringing the driver device close to the connecting device for insertion testing. It also facilitates moving the driver device away from the entrance end of the test bench. After the base plate is moved to the entrance of the test platform by the drive assembly, the top plate slides along the inclined surface of the inclined plate by the inclined block. The top plate drives the insert plate to move upward. At the same time, the contact plate and the baffle are pressed into contact. The connecting rod pushes the two clamping plates to both sides of the base plate, opening the clamping assembly to facilitate the insertion and removal of the driver device. As the drive assembly moves the base plate to the side of the connecting device, the top plate covers the top of the driver device through the second spring and the third spring. The clamping plates clamp the sides of the driver device, completing the automatic clamping limit. The push plate of the first electric push rod pushes from the rear end of the driver device to the side of the connecting device, moving the insertion position of the driver device to the bottom of the slide frame. The clamping range and the position of the insertion position can be adjusted for different models of driver devices. This invention uses a connecting wire of the connecting device to pass through the moving block, placing the plug-in at the front end. After the driver device is placed inside the clamping assembly, a push plate pushes the driver device from back to front, positioning the plug-in position at the bottom of the sliding frame. The third electric push rod inside the vertical plate extends, causing the sliding frame to move vertically. Because the moving frame and the two sides of the sliding frame are connected by plug rods, and the top vertical plate of the sliding frame and the spring telescopic plate at the top of the moving frame are connected by a crossbar, when the clamping assembly moves horizontally with the driving assembly, the sliding frame slides along the plug rods, the spring telescopic plate slides along the crossbar, and pulls the rear slide rail frame to slide along the slide groove, maintaining the connection relationship of each part. Simultaneously, when the sliding frame moves vertically, the plug-in... The rod also drives the moving frame to slide along the slide, and the spring telescopic plate extends and retracts to keep the moving frame and the slide moving synchronously, so that the position of the plug-in corresponds to the plug-in position. The four electric push rods adjust the two slide plates to slide along the inside of the moving groove. The connecting plate drives the vertical plate and the slider inside the slide frame to move. Through the connection of the crossbar, the crossbar slides along the slide rail frame, and the spring telescopic plate drives the moving block to slide along the top of the moving frame, so that the position of the slider and the plug-in can be adjusted synchronously. The position of the slider can be used to locate the position of the plug-in. After the slider and the plug-in are aligned, the plug-in can be accurately plugged in. The second electric push rod pushes the moving frame and the plug-in to move towards the plug-in position, so that the plug-in can be inserted into the plug-in position. This invention uses a recognition lens to scan and identify the plug-in position of the input driver device, thereby determining the accurate location where the plug-in position needs to be connected to the power strip. This allows the position of the sliding plate to be adjusted using the fourth electric push rod inside the top plate, moving the connecting wire and power strip to correspond with the plug-in position for easy and accurate subsequent insertion. For different models of driver devices, the plug-in position is first identified, and then the position of the power strip of the connecting device is adjusted to ensure smooth insertion.

Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, this disclosure proposes an intelligent testing device for a motor driver, comprising: a test bench 1, a drive assembly 6 on the surface of the inlet end of the test bench 1, a clamping assembly 2 on the top of the drive assembly 6, a driver device 3 clamped inside the clamping assembly 2, a test motor 11 fixedly mounted at the tail end of the test bench 1, a connecting device 12 fixedly mounted on the side of the test motor 11 near the driver device 3, and the test motor 11 connected to the connecting device 12 via a cable; two connecting wires 121 fixedly mounted at the front end of the connecting device 12, and plug strips 122 fixedly mounted at the outer ends of the connecting wires 121; two sets of plug positions 31 fixedly mounted on the end of the driver device 3 facing the connecting device 12; the drive assembly 6 includes protrusions 63, two sets of protrusions 63 are provided, the two sets of protrusions 63 are symmetrically fixed on the surface of the test bench 1, and slide blocks 22 are slidably mounted on the protrusions 63; the clamping assembly 2 includes a base plate 21, the bottom of the base plate 21 is fixedly connected to the two slide blocks 22, and the base plate 21... Two clamping plates 27 are slidably installed on the top of the device, and a top plate 28 is provided on the top of the two clamping plates 27. The top plate 28 and the clamping plates 27 are respectively pressed into contact with the top and bottom of the driver device 3. The docking assembly 4 includes a moving frame 45, and two moving blocks 414 are slidably installed inside the moving frame 45. The connecting line 121 is fixedly passed through the moving blocks 414. The two sides of the moving frame 45 are provided with slides 44, and the two ends of the moving frame 45 are slidably sleeved on the slides 44. When using the device, the driver device 3 is placed inside the clamping assembly 2. As the driving assembly 6 pushes the clamping assembly 2 away from the entrance end of the test table 1, the clamping assembly 2 automatically clamps the driver device 3 according to its size. The docking assembly 4 adjusts the plug-in position 31 and the plug bar 122 to the correct plug-in position 31. Then, after approaching the connecting device 12, the plug bar 122 is inserted into the corresponding plug-in position 31. The driver device 3 is tested by the test motor 11. Different models of driver devices 3 can be installed and tested, improving testing efficiency.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the drive assembly 6 further includes: a screw 61 and a drive motor 62. The screw 61 is provided between the two protrusions 63, and one end of the screw 61 is rotatably mounted on the test bench 1. The test bench 1 is fixed with a baffle 14 corresponding to the other end of the screw 61, and the other end of the screw 61 is rotatably mounted on the baffle 14. The drive motor 62 is fixed on the other side of the baffle 14, and the output end of the drive motor 62 is fixedly connected to the screw 61. A screw seat 64 is threaded onto the surface of the screw 61, and the screw seat 64 is fixedly connected to the base plate 21.

[0022] Understandably, the drive motor 62 drives the screw 61 to rotate, and the screw seat 64 and the screw 61 are threaded together to drive the base plate 21 to move along the convex strip 63, so that the driver device 3 is close to the connecting device 12 for insertion test, and it is also convenient to send the driver device 3 away from the entrance end of the test bench 1.

[0023] like Figure 5 , Figure 6 and Figure 9 As shown, in some embodiments, the clamping assembly 2 further includes: an insert plate 29, a second spring 210, a third spring 214, and a bottom groove 215. The bottom of the top plate 28 has a bottom groove 215. The top of the clamping plate 27 is slidably inserted with the insert plate 29, and the top of the insert plate 29 is slidably engaged inside the bottom groove 215. The top two sides of the insert plate 29 are fixed with the second spring 210, and the bottom of the second spring 210 is fixedly connected to the top of the clamping plate 27. The bottom plate 21 has a third spring 214 fixed at both ends inside, and the other end of the third spring 214 is fixedly connected to the bottom of the clamping plate 27. The bottom plate 21 has a movable notch on the side facing the entrance of the test platform 1. The movable notch 23 has a contact plate 24 located at the middle of its outer side. The bottom of the clamping plate 27 is rotatably connected to a connecting rod 26 via a pivot, and the other end of the connecting rod 26 is rotatably connected to the contact plate 24 via a pivot. A first spring 25 is fixed between the contact plate 24 and the base plate 21. A first electric push rod 212 is fixed to the outer side of the clamping plate 27, and a push plate 213 is fixed to the extended end of the first electric push rod 212. The push plate 213 faces the entrance end of the test platform 1. Inclined blocks 211 are fixed to both ends of the top plate 28. Inclined plates 13 are fixed to both sides of the entrance end of the test platform 1. The inclined surfaces of the inclined blocks 211 and the inclined plates 13 are on the same vertical plane.

[0024] Understandably, after the base plate 21 is moved to the entrance of the test bench 1 by the drive assembly 6, the top plate 28 slides along the inclined surface of the inclined plate 13 via the inclined block 211. The top plate 28 drives the insert plate 29 to move upward, while the contact plate 24 presses against the baffle 14. The connecting rod 26 pushes the two clamping plates 27 to both sides of the base plate 21, opening the clamping assembly 2 to facilitate the insertion and removal of the driver device 3. As the drive assembly 6 moves the base plate 21 toward the connecting device 12, the top plate 28 covers the top of the driver device 3 via the second spring 210 and the third spring 214, and the clamping plates 27 clamp the sides of the driver device 3, completing the automatic clamping limit. The push plate 213 of the first electric push rod 212 pushes from the rear end of the driver device 3 toward the side of the connecting device 12, moving the insertion position 31 of the driver device 3 to the bottom of the slide frame 411. The clamping range and the position of the insertion position 31 are adjusted for different models of driver devices 3.

[0025] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the docking assembly 4 further includes: a slide rail frame 41, a slide groove 42, a spring telescopic plate 47, and a crossbar 412. The top of the moving block 414 is fixed with a spring telescopic plate 47, and the top of the spring telescopic plate 47 is slidably inserted with a crossbar 412. A slide rail frame 41 is provided on one side of the tail end of the test platform 1, and the crossbar 412 slides along the inside of the slide rail frame 41. The test platform 1 has a slide groove 42 at the bottom positions on both sides of the slide rail frame 41, and the slide rail frame 41 slides along the slide groove 42. A second electric push rod 43 is fixed on both sides of the bottom of the connecting device 12, and the extended end of the second electric push rod 43 is fixedly connected to the slide frame 44. The top of the insertion position 31 of the driver device 3 is covered with a slide frame 411, and two sliders 413 are slidably installed inside the slide frame 411. The top of the sliders 413 is provided with a vertical plate 4. 8. A vertical groove is provided on the side of the vertical plate 48 facing the connecting device 12, and the other end of the crossbar 412 is slidably engaged in the vertical groove of the vertical plate 48; wherein, a third electric push rod 49 is fixed inside the vertical plate 48, and the extended end of the third electric push rod 49 passes through the bottom of the vertical plate 48 and is fixedly connected to the slider 413; a moving groove 415 is provided inside the top plate 28, and two sliding plates 416 are slidably connected inside the moving groove 415; a connecting plate 410 is fixed on the side of the sliding plate 416 facing the vertical plate 48, and the connecting plate 410 is fixedly connected to the vertical plate 48; wherein, a fourth electric push rod 417 is fixed at both ends of the moving groove 415, and the extended end of the fourth electric push rod 417 is fixedly connected to the sliding plate 416; insert rods 46 are fixed at both ends of the moving frame 45, and the two ends of the sliding frame 411 are slidably sleeved on the surface of the insert rods 46.

[0026] It should be noted that the connection for the electrical performance test of the driver device 3 in this section is specifically designed with a detection unit, which includes an input / output voltage detection module and a pulse signal detection module. The input / output voltage detection module detects the input and output voltages of the motor driver circuit board and makes a judgment based on the difference between the voltage input to the motor driver circuit board and the voltage output from the motor driver circuit board, determining whether the motor driver circuit board can operate normally. The pulse signal detection module detects the pulse signals emitted by the motor driver circuit board and measures the pulse signals emitted by the motor driver circuit board by observation. The measured pulse signal determines the rotation angle of the test motor 11, and the angle of rotation of the test motor 11 is checked against the angle value displayed by the pulse signal. The connecting line 121 of the connecting device 12 passes through the moving block 414, and the plug bar 122 is placed at the front end. After the driver device 3 is placed inside the clamping assembly 2, the push plate 213 pushes the driver device 3 from back to front, placing the plug position 31 at the bottom of the slide frame 411. The slide frame 411 moves vertically through the extended end of the third electric push rod 49 inside the vertical plate 48. Because the moving frame 45 is connected to both sides of the slide frame 411 through the plug rod 46, and the top vertical plate 48 of the slide frame 411 is connected to the moving frame 45, the slide frame 411 is connected to the moving block 414 through the plug rod 46, and the top vertical plate 48 of the slide frame 411 is connected to the moving block 414 through the pulse signal. The spring telescopic plate 47 at the top of the 8 and the movable frame 45 is connected by a crossbar 412. When the clamping assembly 2 moves horizontally with the drive assembly 6, the sliding frame 411 slides along the insertion rod 46, and the spring telescopic plate 47 slides along the crossbar 412, pulling the rear slide rail frame 41 along the slide groove 42 to maintain the connection between the various parts. Simultaneously, when the sliding frame 411 moves vertically, the insertion rod 46 also drives the movable frame 45 to slide along the slide frame 44. The spring telescopic plate 47 extends and retracts to keep the movable frame 45 and the sliding frame 411 moving synchronously, thus aligning the position of the plug bar 122 with the insertion position 31. The two sliding plates 416 are adjusted along the sliding frame 416 by the fourth electric push rod 417. The sliding groove 415 slides inside, and the connecting plate 410 drives the vertical plate 48 and the slider 413 inside the sliding frame 411 to move. The horizontal bar 412 is connected and slides along the slide rail frame 41. The spring telescopic plate 47 drives the moving block 414 to slide along the top of the moving frame 45, and adjusts the position of the slider 413 and the plug 122 simultaneously. The position of the slider 413 can be used to locate the position of the plug. After the slider 413 and the plug 122 are aligned, the plug can be accurately inserted. The second electric push rod 43 pushes the moving frame 45 and the plug 122 to move towards the plugging position 31, so that the plug 122 can be inserted into the plugging position 31.

[0027] like Figure 3 As shown, in some embodiments, rotating frames 5 are fixed on both sides of the entrance end of the test platform 1, and a recognition lens 51 is rotatably mounted on the top of the rotating frame 5.

[0028] It should be noted that the recognition lens 51 can scan and recognize the plug-in position 31 of the inserted driver device 3, thereby determining the accurate position where the plug-in position 31 and the power strip 122 need to be connected. This facilitates the adjustment of the position of the slide plate 416 by the fourth electric push rod 417 inside the top plate 28, moving the connecting wire 121 and the power strip 122 to correspond with the plug-in position 31, which is convenient for accurate subsequent insertion. For different models of driver devices 3, the position of the plug-in position 31 is first identified, and then the position of the power strip 122 of the connecting device 12 is adjusted to ensure smooth insertion.

[0029] Working principle: When using the device, the driver device 3 is placed inside the clamping assembly 2. The recognition lens 51 can scan and identify the insertion position 31 of the driver device 3, thereby determining the accurate position where the insertion position 31 and the power strip 122 need to be connected. This facilitates the adjustment of the position of the slide plate 416 via the fourth electric push rod 417 inside the top plate 28, moving the connecting wire 121 and the power strip 122 to correspond with the insertion position 31, facilitating accurate subsequent insertion. For different models of driver devices 3, the insertion position 31 is identified first, and then the position of the power strip 122 of the connecting device 12 is adjusted to ensure smooth insertion. The drive motor 62 drives the screw 61 to rotate, and the screw seat 64 engages with the screw 61, causing the base plate 21 to move along the convex strip 63, thus moving the driver device. Device 3 is brought close to the connecting device 12 for insertion testing, which also facilitates the removal of the driver device 3 from the entrance end of the test bench 1. The top plate 28 slides along the inclined surface of the inclined plate 13 via the inclined block 211. The top plate 28 drives the insertion plate 29 to move upward, while the contact plate 24 presses against the baffle 14. The connecting rod 26 pushes the two clamping plates 27 towards both sides of the bottom plate 21, opening the clamping assembly 2 to facilitate the insertion and removal of the driver device 3. As the driving assembly 6 moves the bottom plate 21 towards the connecting device 12, the top plate 28 covers the top of the driver device 3 via the second spring 210 and the third spring 214, and the clamping plates 27 clamp the sides of the driver device 3, completing the automatic clamping limit. The push plate 213 of the first electric push rod 212 pushes the driver device 3 out of the driver. The rear end of device 3 is pushed towards the side of connecting device 12, moving the insertion position 31 of driver device 3 to the bottom of slide frame 411. The clamping range and the position of insertion position 31 are adjusted according to different models of driver device 3. The connecting line 121 of connecting device 12 passes through moving block 414, and the plug bar 122 is placed at the front end. After driver device 3 is placed inside clamping assembly 2, push plate 213 is used to push driver device 3 from back to front, placing insertion position 31 at the bottom of slide frame 411. The slide frame 411 is moved vertically by the extended end of the third electric push rod 49 inside vertical plate 48. Because moving frame 45 is connected to both sides of slide frame 411 by plug rod 46, and the top vertical plate 48 of slide frame 411 and the spring telescopic plate 47 at the top of moving frame 45 are connected by vertical rod 46, the slide frame 411 is connected by spring telescopic plate 47. The connection is achieved via a crossbar 412. When the clamping assembly 2 moves horizontally with the drive assembly 6, the sliding frame 411 slides along the insertion rod 46, and the spring telescopic plate 47 slides along the crossbar 412, pulling the rear slide rail frame 41 along the slide groove 42 to maintain the connection between the various parts. Simultaneously, when the sliding frame 411 moves vertically, the insertion rod 46 also drives the moving frame 45 to slide along the slide frame 44. The spring telescopic plate 47 extends and retracts to keep the moving frame 45 and the sliding frame 411 moving synchronously, thus aligning the position of the plug bar 122 with the plug-in position 31. The fourth electric push rod 417 adjusts the sliding of the two slide plates 416 along the inside of the moving groove 415. The connecting plate 410 drives the vertical plate 48 and the slider 413 inside the sliding frame 411 to move. All these connections are achieved via the crossbar 412.The crossbar 412 slides along the slide rail 41, and the spring telescopic plate 47 drives the moving block 414 to slide along the top of the moving frame 45, simultaneously adjusting the positions of the slider 413 and the plug bar 122. The position of the slider 413 can be used to locate the position of the plug bar. After the slider 413 aligns with the plug bar 122, accurate insertion can be ensured. The second electric push rod 43 pushes the moving frame 45 and the plug bar 122 towards the insertion position 31, so that the plug bar 122 can be inserted into the insertion position 31.
