A power socket is provided at the top end of the first substrate 112. The power socket is located outside the support seat 15 and is connected to an external power source. The power socket supplies power to the motor under test. In this embodiment, the first pushing device 113 is a pushing cylinder. The pushing cylinder is disposed outside the first substrate 112. The end of the piston rod of the pushing cylinder is connected to the first substrate 112. The first pushing device 113 pushes the first substrate 112 to move on the first guide rail 111. During the movement of the first substrate 112, the mounting seat 12 is moved from the initial process position to the detection process position, so that the motor under test enters the next process. In other embodiments, the first pushing device 113 can be a motor, a transmission rod, a lead screw, or other common pushing components used by those skilled in the art.

[0064] Please refer to Figure 9 and Figure 10 , Figure 9 which is the first perspective view of the overall structure of the mounting seat in Embodiment 1 of the present invention, Figure 10 and which is the second perspective view of the overall structure of the mounting seat in Embodiment 1 of the present invention.

The second output shaft 43 of the motor under test is disposed on the opening 122. The workpiece table 11 is provided with a through hole. The mounting seat 12 is disposed on the workpiece table 11. The mounting seat 12 is provided with an output pipe 123 that matches the through hole. The output pipe 123 is communicated with the through hole. Specifically, the first output shaft of the motor under test is disposed in the output pipe 123. The output pipe 123 facilitates the insertion of the first output shaft, so that the user can perform tests on other processes on the first output shaft. A plurality of mounting holes are provided at the bottom end of the mounting seat 12. The user can fix the mounting seat 12 to the first substrate 112 through bolts in cooperation with the mounting holes.

[0066] The label detection device 13 is a barcode scanner. A product code is set on the outer surface of the motor to be tested. The product code can be a QR code or a barcode. Before the motor is tested, the label detection device 13 scans the product code of the motor to be tested, and compares the data obtained from the product code with the product data in the database to check whether the motor to be tested is a new product or an old product. If it is an old product, no testing is performed. Only if it is a new product will testing be carried out. The label detection device 13 prevents the motor detection device from repeatedly testing old products, improving the detection efficiency.

[0067] Please refer to Figure 11 , Figure 11 which is a schematic diagram of the overall structure of the support base in Embodiment 1 of the present invention.

[0068] The workbench 1 further includes a first limiting device 14, a support base 15, and a pressing device 16.

[0069] The first limiting device 14 is arranged in the moving direction of the workpiece table 11. The first limiting device 14 includes a limiting bracket and a limiting rod. The limiting rod is arranged on the limiting bracket, and the limiting rod faces the workpiece table 11. The limiting rod can be a hydraulic rod, or the limiting rod can be sleeved with an elastic member, and the limiting rod can provide a certain buffering effect for the first substrate 112 during positioning. When the pushing device pushes the first substrate 112 to move, the limiting device restricts the position of the first substrate 112, so that the mounting seat 12 enters the next working position.

[0070] The support base 15 is arranged on the workpiece table 11. Specifically, the support base 15 is arranged on the first substrate 112, and the support base 15 is arranged in front of the opening 122 of the mounting seat 12. The shape of the top end of the support base 15 matches the shape of the main body part 41 of the motor to be tested. A resistance detection device 151 and a proximity switch 152 are arranged in the middle of the support base 15. The resistance detection device 151 can detect the resistance between the machine shell and the grounding terminal. The resistance detection device 151 can be a detection device such as a high-precision resistance meter. The proximity switch 152 is used to detect whether there is a motor to be tested on the support base 15. A magnetic ring detection device 153 is arranged at the end of the support base 15. The magnetic ring detection device 153 can detect whether the magnetic ring is installed. The magnetic ring detection device 153 includes a Hall sensor. Specifically, the rotation of the motor is controlled by the pulse plus positioning method (PWM), and the Hall output values of phases A and B are collected by the AD module, and relevant measurement parameters are obtained after being processed by the CPU.

[0071] The pressing device 16 is arranged on the first substrate 112, and the pressing device 16 is arranged on the side of the mounting seat 12. The output end of the pressing device 16 can approach or move away from the clamping part 121 of the mounting seat 12. Preferably, the pressing device 16 is a rotary clamping cylinder. The working principle of the rotary clamping is to use air pressure or hydraulic pressure to drive. During operation, the piston first rotates, and after rotating to the designed position and angle, the clamping action is completed. It linearly presses down and clamps the motor to be measured. When the rotary clamping cylinder is in a non-clamping state, the output axis of the rotary clamping cylinder is parallel to the moving direction of the first substrate 112. When the first substrate 112 moves, the output shaft of the rotary clamping cylinder will not interfere with the first substrate 112 or the components on the first substrate 112.

[0072] Please refer to Figure 12 , Figure 12 which is a schematic diagram of the installation structure of the meson detection device in Embodiment 1 of the present invention.

[0073] The output end of the meson detection device 2 faces the mounting seat 12. The meson detection device 2 includes a fixing frame 21, a second pushing device 22, and a displacement sensor 23. The fixing frame 21 is arranged on the first substrate 112, the second pushing device 22 is arranged on the fixing frame 21, and the displacement sensor 23 is arranged on the output end of the second pushing device 22.

[0074] Please refer to Figure 13 , Figure 13 which is a schematic diagram of the structure of the second pushing device in Embodiment 1 of the present invention.

[0075] In this embodiment, the output end of the second pushing device 22 faces the opening 122 of the mounting seat 12. The second pushing device 22 includes a pushing cylinder, a pushing mounting frame 221, and a sensor mounting frame 222. The pushing mounting frame 221 is arranged on the piston rod of the pushing cylinder, the sensor mounting frame 222 is arranged on the pushing mounting frame 221, and the displacement sensor 23 is inserted through the sensor mounting frame. Specifically, the pushing mounting frame 221 is fixed to the piston rod of the pushing cylinder by bolts, the sensor mounting frame 222 is fixed to the pushing mounting frame 221 by bolts, and the sensor can be inserted through the sensor mounting frame 222 by common mounting methods in the art such as flange structure or thread structure. Preferably, the second pushing device 22 further includes a protective cover 223. The protective cover 223 is arranged on the sensor mounting frame 222. The main body part 41 of the protective cover 223 surrounds the output end of the displacement sensor 23, and the protective cover 223 covers the top end and the side end of the output end of the displacement sensor 23 to prevent external dust, particles and other sundries from interfering with the displacement sensor 23.

[0076] In other embodiments, the second pushing device 22 can move the displacement sensor 23 through a pushing mechanism commonly used by those skilled in the art, such as a screw and a transmission gear.

[0077] A recessed portion is provided at the output end of the displacement sensor 23. The displacement sensor 23 sends a control signal to the second pushing device 22. After receiving the control signal, the second pushing device 22 controls the extension or retraction of the output end of the second pushing device 22. Specifically, when the output end of the displacement sensor 23 touches the meson 431 or exceeds a preset moving range, the displacement sensor 23 will send a control signal to the second pushing device 22. The inner side wall of the recessed portion of the displacement sensor 23 is an annular surface, and the shape and size of the recessed portion match the shape and size of the meson 431 to be measured.

[0078] Detection principle: After the motor to be measured is installed and fixed, the meson 431 detection process is then carried out. The initial state of the output end of the second pushing device 22 is the retracted state, and the displacement sensor 23 is preset with a position range value. When starting the meson detection, the second pushing device 22 pushes the displacement sensor 23 towards the motor base. The triggering of the displacement sensor 23 is divided into the following three situations: 1. When the triggering position of the displacement sensor 23 is before the position range value, the displacement sensor 23 sends a control signal to the second pushing device 22. After receiving the control signal, the second pushing device 22 retracts the output end, and the state of the meson 431 is the reverse installation state; 2. When the triggering position of the displacement sensor 23 is within the position range value, the displacement sensor 23 sends a control signal to the second pushing device 22. After receiving the control signal, the second pushing device 22 retracts the output end, and the state of the meson 431 is the normal installation state; 3. When the moving position of the displacement sensor 23 has not been triggered after the position range value, the displacement sensor 23 automatically sends a control signal to the second pushing device 22. After receiving the control signal, the second pushing device 22 retracts the output end, and the state of the meson 431 is the missing installation state. When the installation state of the meson 431 is the reverse installation state or the missing installation state, the meson detection device 2 records the state of the meson 431 and determines that the motor to be measured is unqualified, but the subsequent detection process still proceeds.

[0079] Please refer to Figure 14 , Figure 14 which is a schematic structural diagram of the speed measurement device according to Embodiment 1 of the present invention.

[0080] The meson detection device 2 further includes a speed measurement device 24. The speed measurement device 24 is arranged on the mounting base 12. The speed measurement device 24 includes a speed measurement gear and a speed measurement sensor. The speed measurement gear is arranged on the edge of the opening 122 of the mounting base 12, and the speed measurement sensor is arranged on the mounting base 12. The speed measurement sensor is used to detect the rotation parameters of the speed measurement gear. Specifically, the speed measurement gear meshes with the gear structure of the second output shaft 43 of the motor to be measured. The speed measurement sensor can obtain the rotation parameters of the second output shaft 43 by measuring the rotation parameters of the speed measurement gear and matching the gear ratio of the speed measurement gear and the second output shaft 43. The rotation parameters are mainly speed data.
