Technical Field

[0001] The present application relates to the field of laser technology, and in particular to a laser detection device. Background Art

[0002] Fiber lasers are lasers that use rare earth-doped glass fibers as gain media and are widely used in industrial manufacturing, medical treatment, military defense, and other fields. Before operating a fiber laser, it is necessary to check whether the optical components of the fiber laser are intact and whether there is light leakage from the laser output head of the laser.

[0003] In the prior art, the photo paper is usually placed manually on the light output side of the laser output head, so that the laser output from the laser output head forms a light spot on the photo paper, and the shape of the light spot is observed to determine whether there is light leakage. Due to the instability of manual operation, the position of the photo paper is easily inaccurate, or the photo paper shakes, resulting in a low accuracy problem in detecting whether the fiber laser has light leakage. Utility Model Content

[0004] The embodiment of the present application provides a laser detection device, which aims to solve the problem of low accuracy in the existing detection of whether a fiber laser is leaking light.

[0005] The present application provides a laser detection device, comprising:

[0006] Base;

[0007] A fixing component connected to the base, and used to fix the laser output head;

[0008] The light leakage detection component includes a support frame and a clamping mechanism, wherein the support frame is connected to the base, and the clamping mechanism is used to clamp the photographic paper. The clamping mechanism is movably connected to the support frame and can move between a detection position and an avoidance position relative to the support frame. When the clamping mechanism is in the detection position, the photographic paper located at the clamping mechanism is relatively spaced from the output end of the laser output head. When the clamping mechanism is in the avoidance position, the photographic paper located at the clamping mechanism avoids the laser output from the output end of the laser output head.

[0009] In some embodiments, the clamping mechanism is slidably and rotatably connected to the support frame, so that the clamping mechanism can move between the detection position and the avoidance position.

[0010] In some embodiments, the support frame is provided with a slide groove, and the clamping mechanism includes a sliding member and a clamping structure connected to each other.

The threaded rod passes through the slide groove, one end of the threaded rod is threadedly connected to the clamping structure, and the other end of the threaded rod is connected to the locking portion, and the locking portion is used to abut against the side of the support frame away from the clamping structure.

[0013] In some embodiments, a first positioning portion is protruding from one side of the support frame, and the first positioning portion and the clamping structure are located on the same side of the support frame. When the clamping mechanism is in the detection position, the clamping structure abuts against the first positioning portion to position the clamping structure.

[0014] In some embodiments, a second positioning portion is protruding from one side of the support frame, and the second positioning portion and the clamping structure are located on the same side of the support frame. When the clamping mechanism is in the avoidance position, the clamping structure abuts against the second positioning portion to position the clamping structure.

[0016] In some embodiments, the laser detection device also includes a laser power meter connected to the base, the laser power meter is located on the side of the light leakage detection component away from the fixed component, and the laser power meter is used to receive the laser output by the laser output head and detect the power of the laser.

[0017] In some embodiments, the laser detection device further includes a box body covered on the base, the box body and the base enclose a receiving space, and the fixing component and the light leakage detection component are located in the receiving space.

[0018] The laser detection device provided by the embodiment of the present application is provided with a fixing component for fixing the laser output head on the base, and the clamping mechanism for clamping the photo paper of the light leakage detection component can be moved between the detection position and the avoidance position relative to the support frame. When it is necessary to detect whether the laser has light leakage, the laser output head can be fixed to the fixing component, and the clamping mechanism for clamping the photo paper can be moved to the detection position, so that the photo paper located at the clamping mechanism and the output end of the laser output head are arranged relatively spaced, so that the laser output from the output end of the laser output head can be irradiated to the side of the photo paper and form a light spot on the side of the photo paper, so as to determine whether there is light leakage according to the shape of the light spot on the photo paper. Since the position of the clamping mechanism can be kept stable, the position of the photo paper relative to the laser output head is accurate, and the photo paper is not easy to shake, so that the problem of whether the fiber laser has light leakage can be accurately detected.

[0019] When it is necessary to perform other tests on the laser output from the output end of the laser output head, it is only necessary to move the clamping mechanism to the avoidance position so that the photo paper avoids the laser output from the output end of the laser output head. The operation is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The embodiments of the present application provide a laser detection device, which is described in detail below.

[0034] Figure 1 This is a schematic diagram of the structure of an embodiment of the laser detection device provided in the present application. Figure 1 As shown, the laser detection device 100 includes a base 110, a fixing component 120 and a light leakage detection component 130. The fixing component 120 is connected to the base 110. The fixing component 120 is used to fix the laser output head 200 so that the laser output head 200 can output laser stably. The laser output head 200 is used to connect with the laser body. The laser emitted by the laser body is transmitted to the laser output head 200 and output from the output end of the laser output head 200.

[0035] In some embodiments, Figures 1 to 3 As shown, the laser detection device 100 further includes a light leakage detection component 130 , which is connected to the base 110 and is used to detect whether there is light leakage in the laser output from the output end of the laser output head 200 .

[0036] Among them, Figures 4 to 6As shown, the light leakage detection assembly 130 may include a support frame 131 and a clamping mechanism 132. The support frame 131 is connected to the base 110. The clamping mechanism 132 is used to clamp the photo paper 300. The clamping mechanism 132 is movably connected to the support frame 131 and can be relatively moved in the detection position (such as Figure 3 and Figure 6 as shown) and avoidance position (as shown Figure 2 , Figure 4 and Figure 5 When the clamping mechanism 132 is in the detection position, the photo paper 300 located at the clamping mechanism 132 is spaced relatively from the output end of the laser output head 200, so that the laser output from the output end of the laser output head 200 can irradiate the side of the photo paper 300 and form a light spot on the side of the photo paper 300, so as to determine whether there is light leakage according to the shape of the light spot on the photo paper 300.

[0037] In addition, when the clamping mechanism 132 is in the avoidance position, the photo paper 300 located at the clamping mechanism 132 avoids the laser output from the output end of the laser output head 200, so that the laser output from the output end of the laser output head 200 can irradiate other detection components to detect other parameters of the laser.

[0038] The laser detection device 100 provided in the embodiment of the present application is provided with a fixing component 120 for fixing the laser output head 200 on the base 110, and the clamping mechanism 132 of the light leakage detection component 130 for clamping the photo paper 300 can be moved between the detection position and the avoidance position relative to the support frame 131. When it is necessary to detect whether there is light leakage in the laser, the laser output head 200 can be fixed to the fixing component 120, and the clamping mechanism 132 clamping the photo paper 300 can be moved to the detection position, so that the photo paper 300 located at the clamping mechanism 132 is arranged relative to the output end of the laser output head 200, so that the laser output from the output end of the laser output head 200 can irradiate the side of the photo paper 300 and form a light spot on the side of the photo paper 300, so as to determine whether there is light leakage according to the shape of the light spot on the photo paper 300. Since the position of the clamping mechanism 132 can be kept stable, the position of the photo paper 300 relative to the laser output head 200 is accurate, and the photo paper 300 is not prone to shaking, so that the problem of light leakage of the optical fiber laser can be accurately detected.

[0039] When other tests are required on the laser output from the output end of the laser output head 200, the clamping mechanism 132 only needs to be moved to the avoidance position to allow the photo paper 300 to avoid the laser output from the output end of the laser output head 200. The operation is very convenient.

[0040] In some embodiments, Figures 4 to 6As shown, the clamping mechanism 132 can be slidably connected and rotatably connected to the support frame 131, so that the clamping mechanism 132 can move between the detection position and the avoidance position relative to the support frame 131. That is, the clamping mechanism 132 can rotate relative to the support frame 131 and can slide relative to the support frame 131, so that the clamping mechanism 132 can move between the detection position and the avoidance position more conveniently.

[0041] In other embodiments, the clamping mechanism 132 may be only slidably connected to the support frame 131, so that the clamping mechanism 132 can slide between the detection position and the avoidance position relative to the support frame 131. Alternatively, the clamping mechanism 132 may be only rotatably connected to the support frame 131, so that the clamping mechanism 132 can rotate between the detection position and the avoidance position relative to the support frame 131.

[0042] In some embodiments, a slide groove 1311 can be opened in the support frame 131, and the clamping mechanism 132 includes a sliding member 1321 and a clamping structure 1324 that are connected to each other. The sliding member 1321 is slidably installed in the slide groove 1311 and can rotate in the slide groove 1311, so that the clamping mechanism 132 can be more stably slidably connected and rotatably connected to the support frame 131.

[0043] It is understandable that by sliding the sliding member 1321 in the sliding groove 1311, the clamping mechanism 132 can be driven to slide relative to the support frame 131, so that the clamping mechanism 132 as a whole can slide relative to the support frame 131. In addition, by rotating the sliding member 1321 in the sliding groove 1311, the clamping mechanism 132 can be driven to rotate relative to the support frame 131, so that the clamping mechanism 132 as a whole can rotate relative to the support frame 131.

[0044] Among them, Figure 5 and Figure 6 As shown, the slide groove 1311 on the support frame 131 may include a first groove section 1312 extending in the height direction, and a second groove section 1313 connected to the top of the first groove section 1312, and the extension direction of the second groove section 1313 is perpendicular to the height direction and the light emitting direction of the laser output head 200. Thus, the sliding member 1321 can slide between the first groove section 1312 and the second groove section 1313, and when the sliding member 1321 slides in the first groove section 1312, it can drive the clamping mechanism 132 to move in the height direction, and when the sliding member 1321 slides in the second groove section 1313, it can drive the clamping mechanism 132 to slide in the horizontal direction.

[0045] Specifically, Figure 5As shown, the slide groove 1311 can pass through the support frame 131, and the sliding member 1321 passes through the slide groove 1311, so that the sliding connection and rotation connection between the sliding member 1321 and the slide groove 1311 are more stable. The sliding member 1321 includes a threaded rod 1322 and a locking portion 1323. The threaded rod 1322 passes through the slide groove 1311, one end of the threaded rod 1322 is threadedly connected to the clamping structure 1324, and the other end of the threaded rod 1322 is connected to the locking portion 1323. The locking portion 1323 is used to abut against the side of the support frame 131 away from the clamping structure 1324.

[0046] Thus, by rotating the threaded rod 1322 relative to the clamping structure 1324, the threaded rod 1322 can be moved relative to the clamping structure 1324 along its length direction, so as to drive the locking portion 1323 to approach or move away from the clamping structure 1324. When the locking portion 1323 moves close to the clamping structure 1324 to abut against the support frame 131, the clamping structure 1324 and the support frame 131 can be locked together, so that the position of the clamping structure 1324 remains stable. When the locking portion 1323 moves away from the clamping structure 1324 and separates from the support frame 131, the clamping structure 1324 and the support frame 131 can be unlocked, so that the clamping structure 1324 can slide and rotate relative to the support frame 131.

[0047] In some embodiments, Figure 4 and Figure 6 As shown, a first positioning portion 1315 may be convexly provided on one side of the support frame 131, and the first positioning portion 1315 and the clamping structure 1324 are located on the same side of the support frame 131. When the clamping mechanism 132 is in the detection position, the clamping structure 1324 abuts against the first positioning portion 1315 to position the clamping structure 1324. Thus, the operator moves the clamping structure 1324 to a position abutting against the first positioning portion 1315, and the clamping structure 1324 can be quickly adjusted to the detection position, which is conducive to improving the convenience of use of the laser detection device 100 and improving the detection efficiency of laser light leakage.

[0048] Similarly, a second positioning portion 1316 may be convexly provided on one side of the support frame 131, and the second positioning portion 1316 and the clamping structure 1324 are located on the same side of the support frame 131. When the clamping mechanism 132 is in the avoidance position, the clamping structure 1324 abuts against the second positioning portion 1316 to position the clamping structure 1324. Thus, the operator can quickly adjust the clamping structure 1324 to the avoidance position by moving the clamping structure 1324 to the position where it abuts against the second positioning portion 1316.

[0049] Specifically, a positioning member 1314 may be convexly provided on one side of the support frame 131, and the positioning member 1314 and the clamping structure 1324 are located on the same side of the support frame 131, wherein the first positioning portion 1315 is located at the top of the positioning member 1314, and the second positioning portion 1316 is located at one side of the positioning member 1314 along the extension direction of the second slot section 1313. By moving the clamping structure 1324 to the top of the positioning member 1314 and making the clamping structure 1324 abut against the first positioning portion 1315 at the top of the positioning member 1314, the clamping mechanism 132 can be placed in the detection position; by moving the clamping structure 1324 to one side of the positioning member 1314 along the extension direction of the second slot section 1313 and abutting against the second positioning portion 1316, the clamping mechanism 132 can be placed in the avoidance position.

[0050] In some embodiments, Figures 1 to 3 As shown, the laser detection device 100 may further include a laser power meter 140 connected to the base 110, and the laser power meter 140 is located on the side of the light leakage detection component 130 away from the fixing component 120. When the clamping mechanism 132 is in the avoidance position, the laser output from the output end of the laser output head 200 can be irradiated to the laser power meter 140, so that the laser power meter 140 receives the laser output from the laser output head 200 and detects the power of the laser.

[0051] In addition, the laser detection device 100 may further include a box 150 covered on the base 110, the box 150 and the base 110 enclose a receiving space 151, and the fixing component 120 and the light leakage detection component 130 are located in the receiving space 151. Thus, the laser output from the output end of the laser output head 200 can be isolated by the box 150 to prevent the laser from directly irradiating the human body or other objects and causing damage.

[0052] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
