[0034] The test device proposed in the present application is used to test the servo driver 150 or the servo motor 160. When the servo driver 150 needs to be tested, the servo motor 160 connected to the test device selects a standard test motor, and then all the servo drivers 150 are tested in sequence. When the servo motor 160 needs to be tested, the servo driver 150 connected to the test device selects a standard test driver, and then all the servo motors 160 are tested in sequence. The test device of the present application can test a single-axis servo driver 150 or a multi-axis servo driver 150. The single-axis servo driver 150 is a servo driver 150 with only one drive port, and the multi-axis servo driver 150 is a servo driver 150 with two or more drive ports. The multi-axis servo driver 150 is used to control multiple servo motors 160 separately.

[0035] In one embodiment, Figure 1 As shown, a test device is provided, including: a switch matrix 110, a test bench 120, a data acquisition module 130 and a host computer 140. The switch matrix 110 includes multiple input ports and multiple output ports, each input port corresponds to an output port, and the input port is used to connect to the drive port of the servo driver 150; the test bench 120 includes a test port, all output ports are connected to the test port, and the test port is used to connect to the control port of the servo motor 160; the data acquisition module 130 is used to connect to the shaft of the servo motor 160 and obtain test data; the host computer 140 is respectively connected to the switch matrix 110 and the data acquisition module 130, and the host computer 140 is used to control a group of input ports and output ports in the switch matrix 110 to be conductive, and the host computer 140 is used to obtain test data.

[0036] Specifically, the switch matrix 110 includes multiple groups of controllable switch circuits, one end of each of which is an input port and the other end of each of which is an output port. The switch matrix 110 can turn a specific group of switch circuits on or off under the control of the host computer 140. It will be understood that in the test device of the present application, in order to prevent the drive ports of multiple servo drivers 150 from being interconnected, thereby causing confusion in the drive signals output by the test ports, the switch matrix 110 can be configured to only turn on one group of input ports and output ports at a time. The switch matrix 110 can communicate serially with the host computer 140.

[0037] In some embodiments, the switch matrix 110 includes a plurality of switch units, which may be composed of switching devices such as transistors and relays, and which can be turned on and off according to control signals from the host computer 140. In some other embodiments, the switch matrix 110 further includes a control circuit for controlling the switching devices in the switch units to ensure that they operate according to the set logic and timing. The switch matrix 110 further includes a bus interface for communicating with the host computer 140 to ensure accurate and efficient information transmission. The switch matrix 110 further includes a self-test module for detecting the operating status of all switching devices and locating the position of a faulty switch by opening and closing the switching devices in the switch array. The switch matrix 110 further includes a power supply module for supplying power to other modules in the switch matrix 110. The power supply module provides different voltages to different modules through a linear regulated power supply to ensure stable operation of the entire switch matrix 110.

[0038] The test bench 120 is provided with a test port, one end of which is connected to all output ports in the switch matrix 110, and the other end of the test port is connected to the control port of the servo motor 160, and is used to transmit a drive signal to the servo motor 160, and the drive signal is used to control the servo motor 160. In some embodiments, the test bench 120 is also used to fix the servo motor 160. The data acquisition module 130 is used to connect the rotating shaft of the servo motor 160 to obtain parameter data when the servo motor 160 is running and obtain test data. The test data may include parameters such as the speed, torque, temperature, noise when the servo motor 160 is running, which can be obtained by detecting the sensors in the data acquisition module 130. When collecting test data, the data acquisition module 130 will send the test data to the host computer 140 in real time. The host computer 140 can determine whether the servo driver 150 or the servo motor 160 has design deviations or defects through the obtained test data.

[0039] The following describes the test process of the present application's test device in detail by taking the test servo driver 150 as an example. When the servo driver 150 is tested, the drive ports to be tested on the servo driver 150 are first connected one-to-one with the input ports of the switch matrix 110. After the connection is successful, the host computer 140 controls a group of input ports and output ports in the switch matrix 110 to be turned on, so that the drive ports of the corresponding servo driver 150 are connected to the test ports on the test bench 120. At this time, the drive signal output from the drive port of the servo driver 150 is applied to the control port of the servo motor 160, so that the servo motor 160 starts to rotate. During the rotation of the servo motor 160, the data acquisition module 130 can collect the parameter data of the servo motor 160 in real time, thereby obtaining test data. After the host computer 140 receives the corresponding test data, it can determine whether the drive signal output by the servo driver 150 is normal. It is understood that when testing the servo motor 160, the servo driver 150 can select a standard test driver. The test data of the normal servo motor 160 driven by the test driver is determined. The host computer 140 can compare the obtained test data to determine whether the servo motor 160 is normal. It is understood that the host computer 140 can also process and calculate the obtained test data and customize the output reports and curves according to user requirements, thereby improving testing efficiency.

[0040] When testing the servo driver 150, the above-mentioned test device controls a group of input ports and output ports in the switch matrix 110 through the host computer 140 to conduct, thereby connecting the corresponding drive port of the servo driver 150 to the servo motor 160 to complete the test of one drive port of the servo driver 150. Then, in this way, all drive ports in the servo driver 150 are tested in sequence. Because all output ports of the switch matrix 110 of the present application are connected to the test port, only one servo motor 160 is required to complete the test of multiple drive ports in the servo driver 150, eliminating the need to configure multiple servo motors 160, reducing the space occupied by the test device and lowering the cost of the test device. At the same time, when testing the servo motor 160 through the test device, the performance of multiple servo motors 160 can be tested by replacing the servo motor 160.

[0041] In one embodiment, Figure 2 As shown, the host computer 140 is also used to connect to the communication port of the servo driver 150 , the host computer 140 is used to send driving information to the servo driver 150 , and the host computer 140 is used to receive operating data output by the servo driver 150 .

[0042] Specifically, the host computer 140 in this embodiment is also configured to communicate with the servo driver 150 (e.g., via CAN communication). The host computer 140 can send drive information to the servo driver 150, thereby controlling the drive signal output by the drive port of the servo driver 150 to change the operating state of the servo motor 160, thereby completing testing under different operating states. Simultaneously, the host computer 140 can also receive operating data output by the servo driver 150. The operating data includes information related to motor control and driver status, such as motor position information, motor speed information, motor torque or load information, current and voltage of the drive signal, and fault or error codes. In some other embodiments, when the host computer 140 is not in communication with the servo driver 150, the servo driver 150 can output a fixed drive signal according to an internally stored program when testing the servo driver 150. When testing the servo motor 160, the test driver can also output a fixed drive signal according to an internally stored program.

[0043] In one embodiment, Figure 3 As shown, the data acquisition module 130 includes: a torque sensor 131 and a sensor data acquisition unit 132. The torque sensor 131 is used to connect to the rotating shaft of the servo motor 160. The torque sensor 131 is communicated with the sensor data acquisition unit 132. The sensor data acquisition unit 132 is communicated with the host computer 140.

[0044] Specifically, the torque sensor 131 can be connected to the rotating shaft of the servo motor 160 via a coupling. The torque sensor 131 can convert the physical change in torque into a precise electrical signal, thereby measuring the torsional torque on the rotating shaft of the servo motor 160. In this embodiment, the torque sensor 131 outputs an analog signal. After acquiring the corresponding analog signal, the sensor data acquisition unit 132 processes it and converts it into a digital signal. The sensor data acquisition unit 132 can connect to the host computer 140 via serial communication (RS232 or RS485), thereby transmitting the processed digital signal to the host computer 140 for processing. In other embodiments, the torque sensor 131 can also be a sensor with communication capabilities. It can directly transmit the detected torque information to the host computer 140 via serial communication (RS232 or RS485) or wireless communication (ZigBee, Wi-Fi, Bluetooth, etc.), meeting the testing requirements of different environments.

[0045] In one embodiment, Figure 4 As shown, the data acquisition module 130 further includes: an eddy current brake 133 , the eddy current brake 133 is connected to the torque sensor 131 , and the eddy current brake 133 is communicatively connected to the sensor data acquisition unit 132 .

[0046] Specifically, in this embodiment, one end of the torque sensor 131 is connected to the shaft of the servo motor 160, and the other end of the torque sensor 131 is connected to the eddy current brake 133. The eddy current brake 133 can absorb power by using the principle of eddy current loss, thereby completing the braking of the shaft of the servo motor 160. The host computer 140 can control the eddy current brake 133 through the sensor data acquisition unit 132, and the eddy current brake 133 can change the braking torque under different excitation currents. By setting the eddy current brake 133, the load condition of the servo motor 160 can be simulated, so that the servo motor 160 can be subjected to no-load test, load test, stall test, etc., thereby enriching the testing capability of the testing device.

[0047] In one embodiment, the servo motor 160 is a brushed motor or a brushless motor. The servo motor 160 can also be an AC motor or a DC motor. The servo motor 160 can rotate under the control of a corresponding servo driver 150.

[0048] In one embodiment, Figure 5 As shown, the test bench 120 also includes: a motor fixture 121, and the motor fixture 121 is used to clamp the servo motor 160. Specifically, the test bench 120 in this embodiment is also provided with a motor fixture 121, and the motor fixture 121 is used to clamp and fix the servo motor 160. In some embodiments, the test bench 120 also includes: a slide, and the motor fixture 121 is provided on the slide and can move along the slide. By providing the slide, the distance between the servo motor 160 and the data acquisition module 130 can be adjusted to accommodate servo motors 160 with different shaft lengths. It can be understood that the motor fixture 121 is highly replaceable, and the testing requirements of servo motors 160 of different models can be met by replacing fixtures of different sizes. In some embodiments, the motor fixture 121 is provided with a movable mechanism for adjusting the size of the clamping range of the motor fixture 121.

[0049] The following describes in detail the testing principle of the testing device of the present application using a specific embodiment. Figure 6 The figure shows a schematic diagram of a test device for testing a brushed motor in one embodiment. The control port of the brushed motor includes two connection terminals. The servo driver 150 adjusts the drive signal output by the drive port by receiving the PWM (Pulse Width Modulation) signal sent by the host computer 140. When a group of input ports and output ports of the switch matrix 110 are turned on, the drive signal is transmitted to the test port of the test bench 120, thereby driving the servo motor 160 to rotate. Figure 7Figure 1 shows a schematic diagram of a test apparatus for testing a brushless motor in one embodiment. The brushless motor's control port includes three connection terminals. Servo driver 150 can output drive signals from these ports according to internal program settings. When a set of input and output ports on switch matrix 110 are conductive, the drive signals are transmitted to the test ports on test bench 120, thereby driving servo motor 160.

[0050] In one embodiment, Figure 8 As shown, the present application also proposes a testing method, which is applied to the testing device in the above embodiment. The testing method can be executed by the host computer 140 in the testing device. The testing method includes but is not limited to the following steps:

[0051] Step S210, when a test start instruction is obtained, a group of input ports and output ports in the switch matrix are controlled to be turned on in sequence;

[0052] Step S220: Acquire test data in real time through the data acquisition module.

[0053] Specifically, after the tester connects the test device to the servo driver 150 and servo motor 160 respectively, the tester sends a test start command to the host computer 140 through the user interface. After receiving the test start command, the host computer 140 begins to execute the automatic test program. During the test process, the host computer 140 sequentially controls a group of input ports and output ports in the switch matrix 110 to conduct. When a group of input ports and output ports are conducting, the servo driver 150 sends a drive signal to the servo motor 160 through the conducting switch circuit. The servo motor 160 rotates under the drive signal. At the same time, the data acquisition module 130 acquires test data in real time. After the current drive port test is completed, the host computer 140 controls the next group of input ports and output ports to conduct, thereby testing the next drive port. By looping through the above steps, the test of all drive ports of the servo driver 150 can be completed. After the data acquisition module 130 completes the acquisition of test data, the host computer 140 processes the test data and generates a test report required by the tester.

[0054] In one embodiment, Figure 9 As shown, the test method also includes:

[0055] Step S230, obtaining motor control parameters based on the motor control instruction;

[0056] Step S240: Send the motor control parameters to the servo driver.

[0057] Specifically, in this embodiment, the host computer 140 can communicate with the servo driver 150. The tester can input motor control instructions through the user interface. The motor control instructions are used to indicate the operating state of the servo motor 160, for example, controlling the motor to accelerate or decelerate. After the host computer 140 obtains the motor control instructions, it generates corresponding motor control parameters based on the motor control instructions and sends the motor control parameters to the servo driver 150 to change the operating state of the servo motor 160. For example, if the motor control instruction is to accelerate, the motor control parameters will increase the voltage and current. After receiving the corresponding motor control parameters, the servo driver 150 will increase the voltage and current output to the servo motor 160, thereby increasing the speed of the servo motor 160.
