Fig. 1 is a schematic structural diagram of an embodiment of a laser testing apparatus according to an embodiment of the present application. Fig. 2 is a schematic structural view of one embodiment of a cooling line and a drain line provided in an embodiment of the present application. As shown in fig. 1 and 2, the laser testing apparatus 100 includes a rack 110 and a cooling circuit 120, and the rack 110 is used to support the laser 200 so that the laser testing apparatus 100 can test the laser 200. The laser 200 includes a cooling channel 210. The cooling pipe 120 includes a liquid inlet pipe 121 and a liquid outlet pipe 123, an outlet of the liquid inlet pipe 121 is used for communicating with an inlet of the cooling channel 210, and an inlet of the liquid outlet pipe 123 is used for communicating with an outlet of the cooling channel 210. Thus, the inlet of the liquid inlet pipe 121 may be communicated with the outlet of the cooling liquid circulation assembly (not shown), the outlet of the liquid outlet pipe 123 may be communicated with the inlet of the cooling liquid circulation assembly, then the cooling liquid circulation assembly may supply cooling liquid into the liquid inlet pipe 121 through the inlet of the liquid inlet pipe 121, the cooling liquid may enter the cooling channel 210 of the laser 200 from the outlet of the liquid inlet pipe 121 to cool the laser 200, and then the cooling liquid may enter the liquid outlet pipe 123 from the outlet of the cooling channel 210 and may be discharged from the outlet of the liquid outlet pipe 123 and enter the cooling liquid circulation assembly, so as to realize the circulation flow of the cooling liquid in the cooling channel 210 of the laser 200. The cooling liquid may be water or other liquid capable of cooling the laser 200, without limitation.

The liquid inlet pipe 121 is provided with a first control valve 122 to control the opening or closing of the liquid inlet pipe 121. Thus, when the outlet of the liquid inlet pipe 121 is not in communication with the inlet of the cooling channel 210 of the laser 200, the liquid inlet pipe 121 can be controlled to be closed by the first control valve 122, so that the cooling liquid in the liquid inlet pipe 121 is prevented from flowing out from the outlet of the liquid inlet pipe 121.

In addition, the outlet pipe 123 is provided with a second control valve 124 to control the opening or closing of the outlet pipe 123. Thus, when the inlet of the liquid outlet pipe 123 is not in communication with the outlet of the cooling channel 210 of the laser 200, the liquid outlet pipe 123 can be controlled to be closed by the second control valve 124, so that the cooling liquid in the liquid outlet pipe 123 is prevented from flowing out from the inlet of the liquid outlet pipe 123.

The outlet of the liquid outlet pipe 123 communicates with the housing box, so that the cooling liquid in the liquid outlet pipe 123 flows back into the housing box.

In some embodiments, as shown in fig. 2, the laser testing apparatus 100 further includes a drain line 130, where the drain line 130 includes an air inlet pipe 131 and a drain pipe 134, an outlet of the air inlet pipe 131 is used for communicating with an inlet of the cooling channel 210, the air inlet pipe 131 is provided with a third control valve 132 to control opening or closing of the air inlet pipe 131, an inlet of the drain pipe 134 is used for communicating with an outlet of the cooling channel 210, and the drain pipe 134 is provided with a fourth control valve 135 to control opening or closing of the drain pipe 134.

Thus, after the laser testing apparatus 100 completes the test on the laser 200, the liquid inlet pipe 121 and the liquid outlet pipe 123 of the cooling pipeline 120 can be controlled to be closed by the first control valve 122 and the second control valve 124, and the air inlet pipe 131 and the liquid outlet pipe 134 of the liquid outlet pipeline 130 can be controlled to be opened by the third control valve 132 and the third control valve 132, so that the air inlet pipe 131 is communicated with the air supply device (not shown in the figure), and the air supply device supplies air to the cooling channel 210 of the laser 200 through the air inlet pipe 131, so that the residual cooling liquid in the cooling channel 210 of the laser 200 is blown out to the liquid outlet pipe 134 and discharged from the outlet of the liquid outlet pipe 134, and the problem that the influence of the residual part of the cooling liquid in the cooling channel 210 of the laser 200 on the subsequent transportation and production process of the laser 200 is solved.

Further, since the gas blows out the cooling liquid remaining in the cooling passage 210 to the liquid discharge pipe 134 and is discharged from the outlet of the liquid discharge pipe 134 instead of entering the cooling liquid circulation assembly, it is possible to avoid the problem that the cooling liquid circulation assembly is damaged due to an excessive air pressure in the cooling liquid circulation assembly.

The air supply device may be an air pump or other device capable of providing an air flow, without limitation.

With continued reference to fig. 2, a first check valve 133 is provided on the intake pipe 131, an inlet of the first check valve 133 communicates with an inlet of the intake pipe 131, and an outlet of the first check valve 133 communicates with an outlet of the intake pipe 131. Thereby, the coolant can be prevented from flowing back to the air supply device through the air intake pipe 131 by the first check valve 133, resulting in damage to the air supply device. Wherein the first check valve 133 and the third control valve 132 may be sequentially distributed in the inlet-to-outlet direction of the intake pipe 131. Alternatively, the third control valve 132 and the first check valve 133 may be sequentially arranged in the inlet-to-outlet direction of the intake pipe 131.

Wherein the second check valve 125 and the second control valve 124 may be sequentially distributed along the inlet-to-outlet direction of the liquid outlet pipe 123. Alternatively, the second control valve 124 and the second check valve 125 may be sequentially arranged in the inlet-to-outlet direction of the liquid outlet pipe 123.

The laser testing device of claim 7, wherein the moving mechanism comprises a first slide rail, a first driving member, a second slide rail, a second driving member, two third slide rails and a third driving member, the two third slide rails are connected with the frame and distributed on two sides of the supporting structure, the second slide rail is slidably connected with the third slide rail along the first direction, and the third driving member is connected with the second slide rail to drive the second slide rail to slide relative to the third slide rail; the first sliding rail is in sliding connection with the second sliding rail along the second direction, and the second driving piece is connected with the first sliding rail to drive the first sliding rail to slide relative to the second sliding rail; the temperature detection component is in sliding connection with the first sliding rail along the third direction, and the third driving piece is connected with the temperature detection component so as to drive the temperature detection component to slide relative to the first sliding rail.

9. The laser testing device of any one of claims 1 to 5, further comprising a power testing assembly coupled to the frame and configured to detect the power of the laser.

10. The laser testing device of claim 9, wherein the power testing assembly comprises a housing connected to the frame, and a mount for mounting the laser output head of the laser and a laser power meter for detecting the laser power output by the laser output head, the mount being disposed within the housing.
