Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] See the appendix Figures 1 to 5As shown in the figure, this embodiment provides a TRX testing machine, which includes a frame 1, and a feeding device 2, a power-on device 3, and a workpiece clamping device 4 arranged on the frame. The feeding device 2 includes a coupling fixture tooling 24 on which a plurality of optical devices are fixedly arranged at equal intervals, a slide rail 21 for supporting the coupling fixture tooling 24, a clamping mechanism 23 for clamping the coupling fixture tooling 24, and a conveying mechanism 22 for driving the coupling fixture tooling 24 to move on the slide rail 21. The clamping mechanism 23 is arranged on the conveying mechanism 22. The slide rails are a pair of parallel slide rails. The coupling fixture tooling 24 is installed on the slide rail 21. A clamping groove 241 adapted to the clamping mechanism 23 is arranged on the coupling fixture tooling 24. The conveying mechanism 22 includes a conveying motor 221, a lead screw 224, a slider 222, and a guide rail 223. The guide rail 223 is fixedly arranged on the frame 1. The slider 222 is connected to the guide rail 223 and moves along the guide rail 223. One end of the lead screw 224 is in transmission connection with the conveying motor 221, and the other end passes through the slider 222. The clamping mechanism 23 is arranged on the slider 222. The lead screw 224 serves as a transmission component to convert rotational motion into linear motion. A nut makes the slider 222 move linearly on the guide rail 223 through the spiral groove of the lead screw 224. The guide rail 223 is a platform for supporting the slider 222, ensuring the movement track and stability of the slider 222, and enabling very high position accuracy and repeatability accuracy with a longer service life. The clamping mechanism 23 includes a fixture 233, a lifting cylinder 231 for driving the fixture 233 to lift, and a clamping cylinder 232 for opening or closing the fixture 233. The conveying mechanism 22 operates to drive the clamping mechanism 23, and the clamping mechanism 23 clamps the coupling fixture tooling 24 to complete the feeding and discharging actions. The power-on device 3 is arranged above the slide rail 21 and has two groups, including a telescopic cylinder 32 arranged on the frame 1 and a power-on seat 31 connected to the telescopic cylinder 32. The telescopic cylinder 32 drives the power-on seat 31 to be docked with the communication interface and signal transceiver interface of the optical device for testing. The coupling fixture tooling 24 includes a frame 242. The bottom and top of the frame 242 are beam structures. The surface of the beam is a smooth plane. The beam structure can serve as a slider and be embedded in the slide rail 21 for cooperative movement. A plurality of fixing stations for fixing optical devices are arranged side by side on the frame 242. A fixing groove for fixing the optical device is arranged at each fixing station. The fixing groove is opened at the bottom of the frame 242. A power-on hole 243 corresponding to the optical device is arranged on the bottom surface of the fixing groove. The power-on seat 31 is docked with the power-on hole 243 to test the communication interface. A power-on groove 211 for the power-on seat 31 to enter and exit for docking with the power-on hole 243 is arranged on one side of the slide rail 21. An optical alignment seat 25 is arranged on the signal transceiver interface. The power-on seat 31 is docked with the optical alignment seat 25 to test the signal transceiver interface.The clamping device 4 includes a workpiece fixture 43, a workpiece lifting cylinder 41 for driving the workpiece fixture 43 to lift and lower, and a workpiece clamping cylinder 42 for opening or closing the workpiece fixture 43.

[0024] When the TRX testing machine is running, the drive motor 221 of the conveying mechanism 22 drives the lead screw 224. As a transmission component, the lead screw 224 converts rotational motion into linear motion. The nut enables the slider 222 to move linearly on the guide rail 223 through the helical groove of the lead screw 224. The slider 222 is moved to a position below the coupling jig fixture to be grasped through the control system. The lifting cylinder 231 of the clamping mechanism 23 is activated, and the conveying fixture 233 reaches the designated position. Subsequently, the telescopic cylinder drives the fixture 233 to clamp the positioning slot 241 of the coupling jig fixture 24. Then, the drive motor 221 drives the lead screw 224, causing the slider 222 to drive the coupling jig fixture 24 to reach the designated detection position through the jig clamping mechanism 23. When the workpiece to be detected reaches the detection position, the workpiece lifting cylinder 41 of the clamping device 4 drives the workpiece fixture 43 to reach the designated position. The workpiece clamping cylinder 42 is activated to drive the workpiece fixture 43 to clamp the workpiece to be detected. Subsequently, the two telescopic cylinders 32 are activated, driving the two power supply seats 31 to pass through the slide rail 21 respectively, and docking with the power supply holes 243 and the optical alignment seat 25 through the power supply slots 211 respectively. After the power supply is detected, the control system issues an instruction to activate the workpiece clamping cylinder 42 of the clamping device 4 to release the workpiece. The workpiece lifting cylinder 41 is activated to lower the workpiece fixture 43. Subsequently, the drive motor 221 is activated to convey the next workpiece to be detected to the detection position.

An optical intensifier is connected to each workpiece to be detected on the jig, so that it is possible to avoid frequent disassembly of the workpiece to be detected during the detection process, improving the detection efficiency and the product qualification rate.
