Description

Technical Field

[0001] The present invention relates to an intelligent detection and adjustment device for the horizontal level of a laser base plate and a method for using the same, belonging to the technical field of intelligent detection of lasers. Background Art

[0002] Semiconductor lasers have the characteristics of small size, long life, low power consumption, low price, etc. They can work by a simple injection current method, are compatible with integrated circuits, and can thus be monolithically integrated with them. Moreover, they can directly perform current modulation at a frequency of up to GHz to obtain a laser output with high-speed modulation. Due to these advantages, semiconductor lasers have been widely used in laser communication, optical storage, optical gyroscopes, laser printing, ranging, display, laser lighting, and radar, etc.

[0003] At present, all fiber-coupled lasers mass-produced by enterprises need to go through a series of operation steps such as fixing the laser on a fixing base with screws for aging, etc., which causes the problem of unevenness of the base plate of the fixing base. Especially for lasers requiring specific wavelengths, the uneven base plate will affect the heat dissipation of the laser, thereby causing wavelength drift, affecting test data, resulting in repeated labor problems, and even in severe cases, the laser will fail due to poor heat dissipation. In the prior art, there is a lack of a device for detecting whether the base plate of the laser is horizontal, and for lasers with an obviously uneven base plate, manual flattening is generally used, which has the problems of low precision and inconsistent standards.

[0004] Chinese Patent Document CN212133647U discloses an intelligent level adjustment device. The device includes a level platform, an induction plate, a light emitter, and a controller. The induction plate includes a light sensor and a light receiving hole. The light emitter is provided with a light emitting hole. The lifting device is lifted by a worm screw and is connected to the controller. The detection and adjustment method includes an intelligent detection system and an automatic adjustment system. The intelligent detection system detects whether the platform is level, feeds back the information to the controller, and the controller controls the automatic adjustment system to achieve level after information processing. However, this device adjusts the level by lifting the level platform, which has complex operations, and when used for semiconductor lasers, it can only level the level platform and cannot flatten the base plate of the semiconductor laser. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an intelligent detection and adjustment device for the horizontal level of a laser base plate and a method for using the same. This device can effectively solve the problem of uneven force caused by the uneven base plate during the fixing process of the laser module in the prior art.

[0006] The technical solution of the present invention is as follows:

[0007] An intelligent detection and adjustment device for the horizontal level of a laser base plate, including a base, on which a horizontal induction device and a horizontal adjustment device are arranged, and a controller is arranged inside the base;

[0008] The horizontal induction device includes a horizontal platform, on which an induction plate is arranged. Gravity sensors are arranged at the four corners of the induction plate, and a laser placement table is arranged at the center of the induction plate.

[0009] The horizontal adjustment device includes a fixed rod, on which a first support plate and a second support plate are arranged. The four corners of the first support plate and the second support plate are fixed by connecting rods. A hydraulic cylinder is arranged above the second support plate, a hydraulic telescopic rod is arranged below the hydraulic cylinder, and a pressing tool is arranged below the hydraulic telescopic rod. The hydraulic telescopic rod penetrates through the centers of the first support plate and the second support plate.

[0010] The hydraulic cylinder and the gravity sensors are both electrically connected to the controller.

[0011] Preferably according to the present invention, the gravity sensor is also provided with a display screen capable of displaying the measured value.

[0012] Preferably according to the present invention, a display is also arranged on the side of the base, and the display is electrically connected to the induction plate, the gravity sensor and the controller. It can display the gravity / pressure value of the laser borne at the position of the laser placement table to secondarily judge whether the value displayed by the gravity sensor is accurate. If it is not consistent with the value of the gravity sensor, it feeds back to the controller and continues to adjust the laser bottom plate to the horizontal state.

[0013] Preferably according to the present invention, the pressing tool is located directly above the laser placement table. Ensure that the axis of the pressing tool is consistent with the center of the laser placement table.

[0014] Preferably according to the present invention, a pressure sensor is also arranged on the pressing tool. The pressure sensor can feed back information to the controller to control the pressure between 20 and 40 N.

[0015] Preferably according to the present invention, the pressing tool is a U-shaped pressing tool or a flat pressing tool. The size of the pressing tool can be replaced according to the size of the laser.

[0016] Preferably according to the present invention, a rubber buffer pad is arranged on the pressing tool. Prevent the laser from being scratched by the pressing tool.

[0017] Preferably according to the present invention, rubber buffer seats are arranged below the four corners of the base.

[0018] The usage method of the above intelligent detection and adjustment device for the horizontal of the laser bottom plate is as follows:

[0019] (1) Place the laser to be detected on the laser placement table;

[0020] (2) The laser base plate is in contact with the induction plate. If the laser base plate is uneven, the gravity sensors at the four corners of the induction plate will show inconsistent values. This signal is converted into an electrical signal and fed back to the controller. Then, the controller controls the hydraulic cylinder and the hydraulic telescopic rod to move the press downwards, so that the press contacts the laser and applies pressure until the values on the display screens of the gravity sensors at the four corners are the same as the values on the display, achieving the purpose of adjusting the flatness of the laser base plate.

[0021] The controller in the present invention is an existing single-chip microcomputer or programmable logic controller, and others not elaborated in detail are all prior arts.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The intelligent detection and adjustment device for the laser base plate level in the present invention eliminates the influence of subjective factors such as human factors on the detection of the flatness of the base plate through the level sensing device, solves the problem that people cannot accurately judge whether the laser base plate is flat, and then when the laser base plate is uneven, the laser is pressurized through the level adjustment device to adjust the laser base plate to be flat, overcoming problems such as uneven heat dissipation and wavelength drift caused by the laser base plate.

[0024] 2. The structure of the present invention is simple, the detection and adjustment operations are convenient, and at the same time, it has high precision, intelligence, low manufacturing cost, and can be widely applied in production, solving the problem of inaccurate manual flattening of the laser base plate in the past.
