The beneficial effects of this utility model are that it can limit the qualified parameters of the circuit, improve the measurement speed, facilitate the storage of the wire clamp, facilitate portability, and improve the protection of the observation window. However, it cannot meet the test process requirements of the motor.

[0004] Patent 2: An Electrical Performance Testing Mechanism for a Filter Tester (Publication No.: CN212749077U). This utility model discloses an electrical performance testing mechanism for a filter tester. The electrical performance testing mechanism for a filter tester comprises a lower testing mechanism and an upper testing mechanism mounted on an equipment stand. The lower testing mechanism comprises a four-terminal test socket, while the upper testing mechanism comprises a photoelectric sensing mechanism, a downward pressure mechanism, an air blowing mechanism, and a fixed seat. The photoelectric sensing mechanism comprises a photoelectric sensor, an optical encoder, and a flat key. The downward pressure mechanism comprises a motor, a sliding mechanism, a cylinder mounted on the sliding mechanism, a linear bearing, and an insertion nozzle. The motor drives a cam to rotate, which in turn drives a cam bearing follower to rotate. The linear bearing drives the insertion nozzle to insert into the four-terminal test socket and press against the component. The cylinder actuates to attract and hold the component for testing. When the sensor senses that a component has reached its slot, the upper testing mechanism activates, driven by a stepper motor, and presses downward, pressing the insertion nozzle against the component. The downward pressure of the upper test terminal is driven by the stepper motor, providing flexible and reliable operation. However, this mechanism has structural loads and has purchased parts such as motors and linear bearings, which makes the automation control of the entire equipment complex and costly.

[0045] The working principle of this utility model is:

[0046] In the first step, the first sensor 2-8 has a signal, and the tooling tray 9 carries the workpiece through the conveyor line 8 into the electrical performance testing machine. After arriving at the position, the tray conveyor line 8 stops;

[0047] In the second step, the first cylinder 2-2 starts to push the lifting platform module 3 downward. When the second sensor 2-9 has a signal, the first cylinder 2-2 stops pushing. At this time, the clamping module 7 contacts the workpiece and the compression spring 7-4 is in a compressed state.

[0048] In the third step, the grounding test cylinder 4-2 starts to push the grounding connector 4-4 out. When the third sensor 4-6 sends a signal, the grounding test cylinder 4-2 stops pushing. At this time, the grounding connector 4-4 is docked.

[0049] Step 4: The three-phase resistance test cylinder 5-2 starts to push the three-phase resistance test connector group 5-6 out. When the fourth sensor group 5-5 has a signal, the three-phase resistance test cylinder 5-2 stops pushing. At this time, the three-phase resistance test connector group 5-6 is docked.

[0050] Step 5: The 24-pin low-pressure test cylinder 6-3 starts to push the 24-pin low-pressure head 6-6 out. When the fifth sensor 6-8 has a signal, the 24-pin low-pressure test cylinder 6-3 stops pushing. At this time, the 24-pin low-pressure head 6-6 is docked.

[0051] Step 6: After all three sets of connectors are docked, the test begins. After the electrical performance test is completed, the 24-pin low-voltage test cylinder 6-3 begins to pull the 24-pin low-voltage head 6-6 back. When there is no signal from the fifth sensor 6-8, the 24-pin low-voltage test cylinder 6-3 stops pulling, and the 24-pin low-voltage head 6-6 is disconnected.

[0052] Step 7: The three-phase resistance test cylinder 5-2 starts to pull the three-phase resistance test connector group 5-6 back. When there is no signal from the fourth sensor group 5-5, the three-phase resistance test cylinder 5-2 stops pulling, and the three-phase resistance test connector group 5-6 is disconnected.

[0053] In the eighth step, the grounding test cylinder 4-2 starts to pull the grounding connector 4-4 back. When there is no signal from the third sensor 4-6, the grounding test cylinder 4-2 stops pulling, and the grounding connector 4-4 is disconnected.

[0054] In the ninth step, the first cylinder 2-2 starts to pull the lifting platform module 3 upward. When the first sensor 2-8 receives a signal, the first cylinder 2-2 stops pulling.

[0055] In the tenth step, the first sensor 2-8 has a signal, the tooling tray 9 carries the workpiece out of the electrical performance testing machine through the conveyor line, and the next tooling tray carries the workpiece into the machine.
