The embodiment of the application provides a laser detection device. The following are detailed below.

Fig. 1 is a schematic structural diagram of an embodiment of a laser detection apparatus provided in an embodiment of the present application. As shown in fig. 1, the laser inspection apparatus 100 includes a support 110, and a laser inspection assembly 120 disposed on the support 110, wherein the laser inspection assembly 120 is configured to reflect laser light emitted from an output head of a laser 200 into the output head (not shown) to test the laser 200 for anti-reflection capability.

The laser detection assembly 120 includes a reflector 121 and a laser welding head 122, the reflector 121 is connected to the bracket 110, and the reflector 121 has a light reflection surface 1211. The laser welding head 122 is used to connect with the laser output of the laser 200. The laser welding head 122 is connected to the support 110, and the laser welding head 122 is disposed toward the light reflection surface 1211 such that the light reflection surface 1211 of the light reflection member 121 reflects the laser light emitted from the laser welding head 122 into the laser welding head 122.

It can be understood that, since the laser welding head 122 faces the light reflection surface 1211 of the light reflection member 121, when the output head of the laser 200 is connected to the laser welding head 122 and the output head of the laser 200 outputs laser light, the laser light is irradiated to the light reflection surface 1211 of the light reflection member 121 through the laser welding head 122, and is reflected into the laser welding head 122 by the light reflection surface 1211 of the light reflection member 121 and is reflected into the laser 200 through the output head of the laser 200.

When the laser 200 operates for a certain time or the laser output by the laser 200 reaches a certain power, the light reflecting surface 1211 of the light reflecting member 121 reflects into the laser 200, so that the temperature rise inside the laser 200 is abnormal and even the laser 200 is burned out, thereby determining the limit of the reflected laser that the laser can receive and detecting the anti-reflection capability of the laser 200.

The laser bonding head 122 may be disposed toward the light reflection surface 1211, and the light emitting direction of the laser bonding head 122 may be perpendicular to the light reflection surface 1211 of the light reflection member 121; the angle formed between the light emitting direction of the laser welding head 122 and the light reflecting surface 1211 of the light reflecting member 121 may be close to a right angle, and the laser beam emitted from the laser welding head 122 may be irradiated onto the light reflecting surface 1211 of the light reflecting member 121, and then the light reflecting surface 1211 of the light reflecting member 121 may be reflected into the laser welding head 122.

The material of the light reflecting member 121 includes copper, copper alloy, aluminum alloy, and other materials with high reflectivity, so as to improve the reflectivity of the light reflecting surface 1211 of the light reflecting member 121. Alternatively, the light reflecting surface 1211 of the light reflecting member 121 may be processed to be smooth to improve the light reflectivity of the light reflecting surface 1211 of the light reflecting member 121.

In some embodiments, the laser detection apparatus 100 further comprises a temperature detection assembly 130, and the temperature detection assembly 130 is used for detecting the temperature of the laser 200. When the laser detection device detects the anti-reflection capability of the laser 200, the abnormal temperature rise condition in the laser 200 can be more conveniently acquired, so that the anti-reflection capability of the laser 200 can be more accurately detected.

The temperature detecting assembly 130 may be a thermal imager, which may be connected to the bracket 110, or may be supported on the bottom surface or other positions, and only needs to align the thermal imager with the laser 200 to be detected, and can measure the temperature of the laser 200.

In other embodiments, the temperature detecting component 130 may be a temperature sensor disposed in the laser 200, and the temperature variation in the laser 200 can be obtained by obtaining a temperature signal detected by the temperature sensor.

In some embodiments, the laser inspection device 100 further includes a cooling assembly 140 coupled to the support 110, the cooling assembly 140 coupled to the reflector 121 to cool the reflector 121. It is understood that when the laser beam emitted from the laser welding head 122 irradiates the light reflecting surface 1211 of the light reflecting member 121, the temperature of the light reflecting member 121 increases, and when the temperature of the light reflecting member 121 changes greatly, the light reflecting member 121 deforms to a certain extent, which may cause the laser beam reflected by the light reflecting surface 1211 of the light reflecting member 121 not to be reflected into the laser welding head 122.

Therefore, in the embodiment of the application, the cooling assembly 140 is used for cooling the reflector 121, so that the problem that the reflector 121 is deformed due to the temperature rise of the reflector 121, and the detection of the anti-reflection capability of the laser detection device on the laser 200 is inaccurate can be avoided.

In some embodiments, the cooling assembly 140 includes a cooling member 141, and the cooling member 141 has a cooling duct 142 disposed therein, and the cooling member 141 is connected to the reflector 121 to cool the reflector 121. By filling the cooling medium into the cooling pipeline 142, the cooling member 141 can be cooled quickly, and the cooling effect of the cooling member 141 on the reflector 121 is further improved.

The cooling medium filled in the cooling pipeline 142 may be a cooling liquid, a cooling gas, or the like, and is not limited herein.

Specifically, the cooling member 141 is provided in a plate shape. The cooling channels 142 are located in the cooling member 141 and extend along the plate surface of the cooling member 141, i.e. the cooling channels 142 extend in a direction parallel or substantially parallel to the plate surface of the cooling member 141. The cooling pipeline 142 includes a plurality of straight pipe sections 1421 parallel to the plate surface of the cooling member 141, and the straight pipe sections 1421 are parallel to each other and sequentially distributed along the plate surface of the cooling member 141. The plurality of straight pipe sections 1421 are sequentially communicated through different bent pipe sections 1422 to form the cooling line 142. The inlet 1423 and outlet 1424 of the cooling line 142 open to the side faces of the cooling plate.

The laser inspection apparatus 100 may further include a cooling medium circulation assembly (not shown), an output port of the cooling medium circulation assembly is communicated with the inlet 1423 of the cooling pipeline 142, and an input port of the cooling medium circulation assembly is communicated with the outlet 1424 of the cooling pipeline 142, so as to cool the cooling medium in the cooling pipeline 142. The cooling medium circulation component may include a compressor, a liquid pump, a fan, etc., and may be determined according to the type of cooling medium in the cooling line 142.

Specifically, the cooling medium circulation module includes a water tank and a water pump, an input end of the water pump communicates with the water tank, an output end of the water pump communicates with an inlet 1423 of the cooling pipeline 142, and the water tank communicates with an outlet 1424 of the cooling pipeline 142, so that the water pump can draw cooling water in the water tank into the cooling pipeline 142 during operation, and discharge the cooling water in the cooling pipeline 142 into the water tank, thereby forming water circulation cooling in the cooling pipeline 142.

In other embodiments, the cooling assembly 140 may also be any structure capable of dissipating heat from the light reflecting member 121, such as a semiconductor refrigeration structure, a heat sink, and the like, which will not be described herein again.

In some embodiments, the cooling member 141 is at least partially attached to a surface of the light reflecting member 121 facing away from the light reflecting surface 1211, so as to increase a contact area between the cooling member 141 and the light reflecting member 121, and further increase a cooling effect of the cooling member 141 on the light reflecting member 121. Specifically, the side surface of the cooling member 141 and the surface of the light reflecting member 121 facing away from the light reflecting surface 1211 are attached to each other, so as to further improve the cooling effect of the cooling member 141 on the light reflecting member 121.

The cooling member 141 may be attached to the entire surface of the light reflecting member 121 on the side away from the light reflecting surface 1211, or may be attached to a part of the surface of the light reflecting member 121 on the side away from the light reflecting surface 1211.

In some embodiments, as shown in fig. 1 and 2, the cooling assembly 140 further comprises a clamping structure 150 coupled to the cooling member 141, the clamping structure 150 abutting the light reflecting surface 1211 of the light reflecting member 121. By abutting the holding structure 150 against the light reflecting surface 1211 of the light reflecting member 121, an acting force can be applied to the light reflecting surface 1211 of the light reflecting member 121, so that the surface of the light reflecting member 121 on the side away from the light reflecting surface 1211 is better attached to the cooling member 141, and the cooling effect of the cooling member 141 on the light reflecting member 121 is improved.

The clamping structure 150 includes a clamping member 151, the clamping member 151 includes a clamping portion 1511 and a connecting portion 1514 connected to each other, the connecting portion 1514 is connected to the cooling member 141, and the clamping portion 1511 abuts against the light reflection surface 1211 of the light reflection member 121, so that the clamping portion 1511 applies an acting force to the light reflection surface 1211 of the light reflection member 121, and the surface of the light reflection member 121 on the side away from the light reflection surface 1211 is better attached to the cooling member 141.

The position of the connecting portion 1514 relative to the cooling member 141 is adjustable in the direction from the holding portion 1511 to the cooling member 141 (parallel to the thickness direction of the light reflecting member 121). Thereby, the position of the connecting portion 1514 relative to the reflector 121 can be adjusted, thereby adjusting the distance between the clamping portion 1511 and the cooling member 141. When the light reflecting member 121 and the cooling member 141 need to be connected, the position of the connecting portion 1514 relative to the cooling member 141 may be adjusted to increase the distance between the clamping portion 1511 and the cooling member 141, so as to place the light reflecting member 121 between the clamping portion 1511 and the cooling member 141, and then the position of the connecting portion 1514 relative to the cooling member 141 is adjusted to decrease the distance between the clamping portion 1511 and the cooling member 141, so that the clamping portion 1511 abuts against the light reflecting surface 1211 of the light reflecting member 121.

When the reflector 121 between the clamping portion 1511 and the cooling member 141 needs to be taken out, the position of the connecting portion 1514 relative to the cooling member 141 can be adjusted to increase the distance between the clamping portion 1511 and the cooling member 141, so that the clamping portion 1511 and the light reflection surface 1211 of the reflector 121 can be separated.

Specifically, the connecting portion 1514 of the holder 151 is provided in a columnar shape. The length direction of the connecting portion 1514 is perpendicular to the surface of the cooling member 141 facing the light reflecting member 121. One end of the connecting portion 1514, which is close to the cooling member 141, is screwed to the cooling member 141, and the position of the clamping portion 1511 can be adjusted in the direction from the clamping portion 1511 to the cooling member 141 by rotating the connecting portion 1514. The clamping portion 1511 includes a connecting rod 1512 protruding from a side surface of the connecting portion 1514, and an abutting rod 1513 protruding from an end of the connecting rod 1512 away from the connecting portion 1514 toward the cooling member 141, wherein an end of the abutting rod 1513 toward the cooling member 141 abuts against the light reflecting surface 1211 of the light reflecting member 121.

In other embodiments, the connecting portion 1514 of the clamping member 151 is provided with a through hole, the cooling member 141 is provided with a threaded hole at a position corresponding to the through hole, and one end of a screw is inserted through the through hole and is screwed into the threaded hole, so that the connecting portion 1514 of the clamping member 151 and the cooling member 141 are connected together. Wherein the position of the clamping portion 1511 is adjusted in the direction of the clamping portion 1511 to the cooling member 141 by rotating the screw.

In some embodiments, the number of the clamping members 151 is multiple, and the multiple clamping members 151 are distributed around the light reflecting member 121. Thus, the holding portions 1511 of the plurality of holding members 151 can abut against the light reflecting surface 1211 of the light reflecting member 121, thereby improving the effect of restricting the light reflecting member 121.

Specifically, the light reflecting member 121 is disposed in a plate shape, and the light reflecting surface 1211 is located on a side surface of the light reflecting member 121. The surface of the light reflecting member 121 facing away from the light reflecting surface 1211 is attached to the surface of the cooling member 141. The number of the clamping members 151 is 4, the 4 clamping members 151 are distributed around the reflector 121, and the clamping portions 1511 of the 4 clamping members 151 are all abutted against the light reflecting surface 1211 of the reflector 121.

In some embodiments, as shown in fig. 1, the bracket 110 includes a base 111 and a fixing frame 112 connected to the base 111, the fixing frame 112 includes a fixing portion 113 spaced apart from the base 111, the cooling element 140 is disposed on a side of the base 111 facing the fixing portion 113, the light reflecting element 121 is disposed on a side of the cooling element 140 facing the fixing portion 113, and the fixing portion 113 is connected to the laser welding head 122, so that the laser welding head 122 is disposed facing the light reflecting surface 1211.
