[0050] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments shown in the drawings are examples and are intended to explain the present application, and should not be construed as limiting the present application.

[0051] The laser beam combiner detection calibration device of the embodiments of the present application is described below with reference to the accompanying drawings.

[0052] As shown in Figure 1 and Figure 2 , a laser beam combiner detection calibration device comprises a sleeve 1, two plane lenses 2, three mechanical shutters 3, a plano-concave lens 4, a cantilever 5, a mounting ring 6, a rotary table 7 and a base 8, wherein,

[0053] The sleeve 1 is provided with an ear seat 10, the two ends of the cantilever 5 are connected to the ear seat 10 and the mounting ring 6 respectively, and the mounting ring 6, the rotary table 7 and the base 8 are connected in sequence;

[0054] The two plane lenses 2 are arranged at the two ends of the sleeve 1 respectively;

[0055] The three mechanical shutters 3 and the plano-concave lens 4 are arranged in the sleeve 1, and the axes of the sleeve 1, the two plane lenses 2, the three mechanical shutters 3, the plano-concave lens 4 and the rotary table 7 coincide;

[0056] The concave surface of the plano-concave lens 4 points to the base 8, two mechanical shutters 3 are arranged on one side of the concave surface of the plano-concave lens 4, and the other mechanical shutter 3 is arranged on one side of the plane of the plano-concave lens 4;

[0057] As shown in Figure 3 and Figure 4 , the baffle of the mechanical shutter 3 is provided with a silicon wafer 31 and a distance sensor 32.

[0058] In this embodiment of the invention, two mechanical irises 3 are used to determine whether the diameter of the laser beam of the laser beam combiner meets the requirements, and a plano-concave lens 4 and another mechanical iris 3 are used to determine whether the laser beam of the laser beam combiner is collimated.

[0059] Specifically, the relevant personnel install the device on the laser beam emitting head of the laser beam combiner via the base 8, and start the laser beam combiner to emit a laser beam, allowing the laser beam to pass through the device;

[0060] like Figure 5 As shown, laser beam I passes through the base 8, turntable 7 and mounting ring 6, and enters the sleeve 1 through the plane lens 2. Laser beam I will first pass through two mechanical irises 3. The first of the two mechanical irises 3 is used to determine whether the diameter of laser beam I exceeds the maximum diameter value, and the second is used to determine whether laser beam I is smaller than the minimum diameter value.

[0061] For example, when the diameter of the laser beam I is required to be 1 ± 0.05 mm, then the middle channel of the first of the two mechanical irises 3 is adjusted to 1 to 1.05 mm, and the middle channel of the second is adjusted to 0.95 to 1 mm;

[0062] When laser beam I passes through the first of the two mechanical irises 3, if the diameter of laser beam I does not exceed the maximum diameter, then laser beam I will not irradiate the mechanical iris 3, and consequently will not irradiate the silicon wafer 31; if the diameter of laser beam I exceeds the maximum diameter, then laser beam I will irradiate the mechanical iris 3, and consequently irradiate the silicon wafer 31 and generate current due to the photoelectric effect, which indicates that the diameter of laser beam I is out of range.

[0063] When laser beam I passes through the second of the two mechanical irises 3, if the diameter of laser beam I is not less than the minimum diameter, then laser beam I will irradiate the mechanical iris 3, and in turn irradiate the silicon wafer 31 and generate current due to the photoelectric effect; if the diameter of laser beam I is less than the minimum diameter, then laser beam I will not irradiate the mechanical iris 3, and in turn will not irradiate the silicon wafer 31, which indicates that the diameter of laser beam I is less than the minimum diameter.

[0064] By using a current detection device to read the current generated by the silicon wafers 31 on the two mechanical irises 3, relevant personnel can determine whether the diameter of the laser beam I meets the requirements.

[0065] Another mechanical iris 3 and plano-concave lens 4 are used to determine the collimation of the laser beam combiner;

[0066] like Figure 6 As shown, if the laser beam II is not tilted during collimation, the laser beam II passes through the axis of the plano-concave lens 4 and through the middle channel of the mechanical iris 3, and will not irradiate the silicon wafer on the mechanical iris 3.

[0067] As Figure 7 shown, if the laser beam III is not collimated and tilted, the laser beam III passes through the plano-concave lens 4 and is reflected thereon to irradiate the mechanical iris 3 and the silicon wafer on the mechanical iris 3, and further generates current due to the photoelectric effect, and the relevant staff can determine whether the laser beam III is collimated and tilted by reading the current generated by the silicon wafer 31 on the mechanical iris 3 through the current detection device.

[0068] The laser beam combiner detection and calibration device disclosed in the utility model can avoid misjudgment in the traditional manual detection process, determine whether the diameter of the laser beam of the laser beam combiner meets the requirements or is tilted through three mechanical irises and a plano-concave lens, and ensure that the laser of the laser beam combiner is qualified.

[0069] It should be noted that the mechanical iris 3 is driven by an ultrasonic motor to accurately control the diameter of the middle channel of the mechanical iris 3.

[0070] Furthermore, the ear seat 10 and the rotary table 7 are respectively provided with butterfly bolts 11.

[0071] In addition, it should be noted that the base 8 is provided with a magnetic suction piece 9 and a bolt seat 12.

[0072] The relevant staff can also install the device on the laser beam combiner at a suitable position according to the actual situation through the cooperation of the bolt and the bolt seat 12.

[0073] In addition, it should be noted that the laser pointer 13, the mounting rod 14 and the two connecting rods 15 are further included, wherein,

[0074] The two connecting rods 15 are respectively arranged on the sleeve 1.

[0075] The laser pointer 13 is arranged on the end of the sleeve 1 away from the base 8, one end of the mounting rod 14 is connected with one connecting rod 15 in a shaft mode, and the other end of the mounting rod 14 is movably connected with the other connecting rod 15.

[0076] The laser pointer 13 is arranged on the mounting rod 14.

[0077] The laser of the laser pointer 13 coincides with the axis of the sleeve 1.

[0078] Magnets 16 are arranged at the connection between the mounting rod 14 and the connecting rod 15.

[0079] According to actual conditions, the related staff can use the laser pointer 13 as the preliminary adjustment of the device, the related staff fixes the laser pointer 13 at the axis of the sleeve 1, and makes the laser of the laser pointer 13 point to the target position, at this time, the sleeve 1 is fixed through the butterfly bolt 11, and the mounting rod 14 is rotated to make the laser pointer 13 away from the sleeve 1.

[0080] The connecting positions of the sleeve 1 and the two plane lenses 2, the three mechanical iris 3 and the flat concave lens 4 are respectively provided with ceramic sealing washers.

[0081] According to the device, the misjudgment in the traditional manual detection process can be avoided, whether the diameter of the laser beam of the laser beam combiner meets the requirements or is inclined is judged through the three mechanical irises and the flat concave lens, and the qualified laser of the laser beam combiner is ensured.
