Description

Technical Field

[0001] The utility model relates to the technical field of lasers, in particular to an installation and adjustment structure of a micro laser. Background Art

[0002] As the core component of optical systems, lasers are widely used in gas analysis, laser medical treatment, laser printing, laser ranging, laser radar, fiber optic communication, optical storage, infrared lighting, laser pointers, atmospheric monitoring and chemical spectroscopy. With the advancement of electronic technology and optical detection technology, new, high-performance, miniaturized advanced optical systems are rapidly updated, which is the development trend of international advanced optical technology and a technical bottleneck of optical analytical instruments.

[0003] When the laser is installed in a product, it is generally necessary to use various horizontal and vertical adjustment devices, and then cooperate with the gluing and fixing process to assist in installation and adjustment. The existing method is not suitable for miniaturized optical systems, fine-tuning is difficult, and there are problems such as poor laser heat dissipation, complex adjustment and calibration, troublesome disassembly and production line layout, poor installation consistency, and the laser fixed with glue has the risk of falling off after long-term use.

[0004] Therefore, the existing laser installation structure has problems such as unstable fixation and poor installation consistency. In addition, there are also problems such as large laser volume, poor heat dissipation effect, and complex and imprecise adjustment and calibration. Utility Model Content

[0005] Based on the problems pointed out in the background technology that the existing laser installation structure has the problems of unreliable fixation and poor installation consistency, as well as large laser size, poor heat dissipation effect, and complex and imprecise adjustment and calibration, the purpose of this application is to propose an installation and adjustment structure for a micro laser. The installation and adjustment device effectively reduces the size and weight of the whole machine, is firmly fixed and easy to install, and at the same time, the laser has good heat dissipation effect, thereby improving the adjustment accuracy and working stability of the laser.

[0006] The utility model is realized by the following technical solutions:

[0007] The present application provides an installation and adjustment structure for a micro laser, including a base for installing the laser, wherein the base is provided with a three-layer adjustment mechanism, including a fixing layer, an adjustment layer and a mounting layer, wherein the fixing layer, the adjustment layer and the mounting layer are clearance-matched in sequence to form a first gap and a second gap, and connecting piles are symmetrically arranged at the two gaps.

[0008] Among them, when the base size is 18mm×16mm, a laser with a size of 11.5mm×7.5mm×8.5mm can be installed.

[0009] The installation and adjustment structure of the micro laser uses a groove structure design, combined with a thin and light flexible circuit board, to simplify the structure and effectively reduce the size and weight of the whole machine. At the same time, it adopts a screw fixing method to make the installation and adjustment structure firmly fixed and easy to install. The base is set as a three-layer adjustment mechanism with a fixed layer, an adjustment layer, and a mounting layer, which very conveniently realizes the ±6° deflection adjustment of the laser within a 360° plane. At the same time, the heat dissipation effect is improved by using metal heat transfer and increasing the contact area, thereby improving the adjustment accuracy and working stability of the laser.

[0010] Furthermore, a control board for driving the laser and collecting signals is connected to the bottom of the base.

[0011] Furthermore, the control panel is fixedly matched with the outer bottom surface of the base by screws.

[0012] Furthermore, the base and the control panel are correspondingly provided with a threaded hole, a first through hole, a second through hole, a groove, a wire hole, a first fixing hole, a second fixing hole, and a limit hole.

[0013] Furthermore, the laser also includes a heat conductive sheet and a pin. The laser is built into the base and fixed by screws passing through the first fixing hole. The heat conductive sheet is tightly fitted to the top inner wall of the base fixing layer to achieve metal heat transfer; the pin passes through the wire holes and grooves set in the base and is electrically connected to the control board.

[0014] Furthermore, the control board also includes a flexible cable interface, and a screw passes through the second fixing hole to fix the control board to the outer bottom surface of the base.

[0015] Among them, the flexible cable interface is used to connect and transmit control signals.

[0016] Furthermore, a groove is provided on the base, and the groove isolates the control panel from the base by air after installation.

[0017] By arranging a groove on the base, the control board is isolated from the base by air, which further enhances the heat dissipation and reduces the electrical and thermal interference.

[0018] Furthermore, the control board is a flexible circuit board.

[0019] The control board can be a flexible circuit board that is thin, small, and has good heat dissipation.

[0020] Furthermore, the mounting layer of the base is provided with limiting holes.

[0021] By arranging the limiting holes on the mounting layer of the base, the base can be installed quickly and consistently, and the base can be fixed at the corresponding installation point by passing the screws through the second through holes.

[0022] Furthermore, a heat-conducting layer is coated on the contact surface between the heat-conducting sheet and the base.

[0023] The heat-conducting layer coated on the contact surface between the heat-conducting sheet and the base may be thermal grease, and the heat-conducting effect may be further enhanced by coating the thermal grease.

[0024] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0025] (1) The installation and adjustment structure of the micro laser in the present application uses a groove structure design, combined with a thin and light flexible circuit board, to simplify the structure, effectively reduce the volume and weight of the whole machine, and adopt a screw fixing method, which is not only firmly fixed but also easy to install;

[0026] (2) In the installation and adjustment structure of the micro laser in the present application, the base is provided with a three-layer adjustment mechanism of a fixed layer, an adjustment layer, and a mounting layer, which conveniently realizes the ±6° deflection adjustment of the laser within a 360° plane. At the same time, the heat dissipation effect is improved by utilizing metal heat transfer and increasing the contact area, thereby enhancing the adjustment accuracy and working stability of the laser.
