[0044] See Figure 4 The linear guide 2 includes a slide rail 21, a sliding stop block 22, a slider 23, and a micro switch 24. The slider 23 is slidably connected to the slide rail 21. A sliding stop block 22 is installed at each end of the slide rail 21. A micro switch 24 is installed on the sliding stop block 22 to detect the sliding position of the slider 23.

[0045] See Figure 5The top cylinder 7 includes a cylinder body 71, a magnetic switch 72, and a pressure sensor 73. The magnetic switch 72 is mounted on the side of the cylinder body 71, and the pressure sensor 73 is mounted on the end of the piston rod of the cylinder body 71. After the piston rod of the cylinder body 71 extends, the measuring end of the pressure sensor 73 presses against the pressure plate 51 on top of the counterweight 5. The pressure sensor 73 measures the maximum thrust value reached by the electric actuator and feeds this value back to the PLC control system. When the maximum thrust reaches the holding time, the piston rod of the top cylinder 7 retracts, and the measuring end of the pressure sensor 73 separates from the pressure plate 51 on top of the counterweight 5.

[0046] In this invention, the load includes the weight of the counterweight 5 and the pressure applied by the top cylinder 7. By inputting the corresponding air pressure into the top cylinder 7, the pressure applied by the top cylinder 7 can be adjusted to achieve different load value requirements.

[0047] See Figure 6 In the forward or reverse assembly station, the mounting block includes two T-shaped mounting blocks 81. Each T-shaped mounting block 81 has a through hole on its vertical surface, and a buffer pad 82 is installed inside the through hole of one of the T-shaped mounting blocks 81. In the reverse assembly station, the mounting block also includes an n-shaped mounting block 83, such as... Figure 8 As shown. An n-type mounting block 83 is installed between two T-type mounting blocks 81, and a through hole is provided on the vertical surface of the n-type mounting block 83.

[0048] See Figure 9 The pull-rope sensor 6 includes a pull-rope sensor body 61, a pull-rope sensor bracket 62, a plastic part 63, and a connector 64. The pull-rope sensor body 61 is mounted on the bottom of the crossbeam using the pull-rope sensor bracket 62. The pull-rope of the pull-rope sensor body 61 passes through the connector 64, and the plastic part 63 at the end of the pull-rope is secured to the bottom of the connector. The connector 64 is connected to the counterweight 5. The pull-rope sensor 6 is used to measure the extension and retraction lengths of the electric actuator.

[0049] See Figure 10 The support rod assembly 9 includes a base plate 91 and a support rod body 92. The upper end of the support rod body 92 is connected to the bottom of the counterweight 5, and the lower end of the support rod body 92 is connected to the base plate 91. The front of the base plate 91 has a notch, within which the electric actuator 4 is located. Three laser displacement sensors 10 are installed around the notch at a 120° angle. The three laser displacement sensors 10 are used to measure the runout value of the guide rod when the electric actuator extends or retracts. The laser displacement sensors 10 are high-precision laser displacement sensors, achieving a runout measurement accuracy of 0.01mm, fully meeting testing requirements.

[0050] A transparent protective plate 18 is provided on the upper part of the frame 1. To prevent safety hazards caused by the actuator suddenly falling, slipping out or falling off during the test, the transparent protective plate 18 is designed to protect personal safety while not hindering monitoring during the test.

[0051] In operation, the electric actuator 4 to be tested is removed, and its bottom end is fixed to the bottom connector of the workstation under test. The electric actuator 4 is scanned, and the PLC reads the QR code information. Then, the two-hand start button is pressed, and the motor model and rated voltage information of the electric actuator 4 are determined by the QR code information. The push rod of the electric actuator 4 extends and pushes the counterweight 5 with a rated load of 114 kg upwards. At this time, the PLC begins to measure the maximum current during the upward movement and the runout value of the push rod of the electric actuator 4 during the upward movement.

[0052] When the electric actuator 4 pushes the counterweight 5 to the set point, it applies an additional load of 226 kg to the counterweight 5 through the top cylinder 7. The additional load is the thrust of the piston rod of the top cylinder 7. By inputting a specific air pressure to the top cylinder 7, the thrust of the top cylinder 7 reaches the maximum load value required for the test of the electric actuator 4.

[0053] The electric actuator 4 pushes the counterweight 5 to the stroke value set by the system and holds it for about 2 seconds. Then the piston rod of the top cylinder 7 retracts automatically. At this time, the PLC measures the maximum current of the increased load.

[0054] When the electric actuator 4 extends to its maximum stroke, the PLC system automatically calculates the average rising speed of the actuator, the maximum rising jump value, the maximum current value under rated load, the maximum current value under increased load, the extension stroke of the electric actuator 4, and the number of pulse signals when the electric actuator 4 rises.

[0055] The electric actuator 4 retracts its push rod, and measures its average descent speed, maximum descent bounce, maximum descent load current, descent stroke, and number of descent pulse signals.

[0056] After the electric actuator 4 descends to the zero position, the descent operation ends. The PLC system automatically calculates the actuator's average descent speed, maximum descent runout, maximum descent load current, descent retraction stroke, and number of descent pulse signals. The host computer reads and stores all the measurement results of the ascent and descent. At this time, the three-color indicator light at the corresponding test station automatically displays green or red, indicating whether the test is qualified or unqualified.

[0057] This invention enables the application of loads during motor drive and electric actuator testing, measurement of electric actuator stroke, measurement of runout during electric actuator extension, measurement of current value during electric actuator operation, measurement of electric actuator running speed, and measurement of the number of pulse signals generated by the electric actuator during rise and fall. It can store the measurement results for each product, facilitating product traceability.

[0058] This invention employs a design with different workstations to meet the testing requirements of solar-powered electric actuators in both upright and inverted installations, thereby verifying the functionality of the electric actuators under different installation conditions. This invention offers advantages such as convenient load adjustment, high efficiency and precision, and good stability.
