Description

Technical Field

[0001] The utility model relates to the field of laser measurement, in particular to a laser tool system. Background Art

[0002] Laser tool systems are increasingly used in construction fields such as renovation and decoration, as well as in people's daily lives. There are many types of laser tool systems, including laser levels, laser rangefinders, laser levelers, etc.

[0003] The light source of existing laser tools is provided by laser diodes. Semiconductors are used as gain media in laser diodes. Light is generated by exciting electrons through electrical injection. Its working principle is similar to that of LEDs. In a specific "cavity", light is repeatedly reflected to enhance its intensity, and finally the laser is output. However, due to the limitations of the semiconductor device structure characteristics of the laser diode itself, the laser diode has a series of defects, and thus cannot meet the users' increasingly high requirements for the laser quality of laser tools. The defects of laser diodes include: beam divergence, which makes the spot larger; asymmetric beam, which makes the spot elliptical; unstable mode, which fluctuates greatly with the current; temperature stability problems, with temperature changes, the current, power, wavelength and beam quality will fluctuate; the quality of the beam itself is relatively poor, and uneven spots and uneven energy distribution are prone to occur; the laser emission distance is limited and there are light leakage problems.

[0004] Since the laser diode itself has the above-mentioned defects, additional debugging circuit modules and optical mirrors have to be set up in the laser tool to correct these shortcomings, which leads to an increase in the number of auxiliary structures set up inside the laser tool; and even if auxiliary structures such as debugging circuit modules and optical glass components are set up, these defects of the laser diode cannot completely solve the above-mentioned defects.

[0005] Therefore, in order to completely eliminate the above defects, improve the laser light quality, and simplify the structure of the laser tool, the utility model provides a laser tool, which for the first time replaces the fiber laser with a laser diode as the light source of the laser tool. Since the light emitted by the fiber laser is of high quality and the power is not affected by temperature, the laser quality defects of the above laser diode are eliminated, the structure is simplified, and the performance of the laser tool is improved. Utility Model Content

[0011] The optical module is connected to the laser tool. The standard laser beam is transformed by the optical module to form one or more laser spots or laser beams, and enters the laser tool as the output laser of the laser tool.

[0012] Furthermore, the fiber laser module is located outside the housing of the laser tool system.

[0013] Furthermore, the laser tool system also includes: a mounting groove arranged outside the shell or inside the shell, and the optical fiber is installed in the mounting groove; the optical module passes through the shell and is connected to the laser tool.

[0014] Furthermore, the laser tool system also includes: an optical fiber fixing component for fixing the optical fiber into a coil shape.

[0016] Furthermore, the fiber laser module also includes: a control unit, and the control unit is used to adjust the parameters of the laser.

[0017] Furthermore, the laser tool system includes at least one of a laser level, a laser rangefinder or a laser sweeper.

[0019] 1. Fiber lasers are creatively applied to laser tools, which greatly improves the quality of laser light sources and the performance of laser tools, achieving unexpected technical effects.

[0020] 2.

[0035] See also Figure 1 , is a structural diagram of a laser tool system in accordance with a preferred embodiment of the utility model. The laser tool system of the utility model comprises: a fiber laser module, an optical fiber 3, an optical module 4 and a laser tool 1. The laser tool 1 comprises at least one of a laser level, a laser rangefinder or a laser sweeper.

[0036] exist Figure 1 Based on Figure 2 , the fiber laser module includes: a fiber laser. Compared with the laser module formed by the laser diode as the emission source in the prior art, the laser beam generated by the fiber laser has very good uniformity, no bad light quality such as stray light, no light spot halo, no stray light, and low beam divergence; in addition, it can withstand greater temperature changes. The laser tool 1 in the prior art will increase the discharge amount under high temperature conditions, but the fiber 3 measurement tool of the utility model no longer has power fluctuations or even triggers circuit protection frequency reduction, and multiple directions can maintain the same power, and will not be affected by the temperature increase caused by the power increase, so that the power used can be greatly improved, which is especially important for high-precision machines.

[0037] The optical fiber 3 includes: an optical fiber 3 line and a plurality of optical fiber heads arranged in the optical fiber 3 line; the optical fiber head is a standard light spot generator, and its function is equivalent to an optical lens such as a sleeve and a focusing lens. Therefore, compared with the prior art, the technical solution provided by the utility model does not need to generate a laser beam again through an optical lens such as a sleeve and a focusing lens, thereby simplifying the structure and improving convenience. The length and diameter of the optical fiber 3 line are determined according to the requirements of the required standard laser beam. By setting the length and diameter of different optical fibers 3 lines, standard laser beams of different sizes can be generated to meet the customer's needs for different laser tools 1. At the same time, the optical fiber 3 line can be appropriately bent like an electric wire, and the flexibility when installed on the machine is increased.

[0038] The optical module 4 includes a reflector or a cylindrical mirror.

[0039] The fiber laser is connected to the optical module 4 via the optical fiber 3. The laser emitted by the fiber laser generates a standard laser beam through the optical fiber 3 and is transmitted to the optical module 4. The optical module 4 is connected to the laser tool 1. Since the standard laser beam generated by the optical fiber head is a circular laser spot, more changes need to be made in the laser tool 1, such as splitting a point light source into multiple laser spots or laser beams. Therefore, the optical module 4 is set to convert the standard laser beam generated by the optical fiber 3 into one or more laser spots or laser beams.

[0040] In this embodiment, the optical module 4 is connected to the inner core of the laser tool 1 through the housing 11. One or more laser light spots or laser light rays generated by the optical module 4 enter the laser tool 1 after being processed by the inner core, and serve as the output laser of the laser tool 1. The inner core is used to maintain the stability of the output laser; the one or more laser light spots or laser light rays generated by the optical module 4 may be, for example, one or more 180°, 360° laser lines.

[0041] In the fiber optic measuring tool provided in this embodiment, the emission source in the fiber optic laser module is replaced by a fiber optic laser by a laser diode. Due to the improvement in laser quality, the performance of laser tools such as laser levels, laser rangefinders, and laser sweepers is greatly improved. Since the quality of laser is not comparable to that of a laser diode, the output laser of equivalent or slightly higher quality than that of a laser diode is provided, and the power required is greatly reduced, thereby saving power consumption. In particular, the power consumption of a laser sweeper will be very small. It can be seen that the application of fiber optic lasers in laser tools has produced unexpected technical effects.

[0042] Specifically, the technical solution provided by the utility model has the following unexpected improvements to the performance of the laser rangefinder: there is no light loss in long-distance transmission, when light is generated, the receiving distance can be enhanced by using a receiving device such as a receiver, and when a light spot is generated, the light spot is a circular light spot, and the diameter of the light spot is not affected at a certain distance. For example, even at 10m, the change in the light spot is very small, so that when the user uses it at a distance, it will not be unable to use it because the light spot becomes larger. This is far from comparable in measuring tools that use laser diodes as laser light sources. In addition, when the laser rangefinder is working, a part of it generates diffusely reflected light by emitting laser lines to the irradiated surface. After the fiber laser replaces the laser diode as the emission source, the receiving performance and receiving distance of the laser rangefinder that generates light signals by receiving diffusely reflected light are also greatly enhanced.

[0043] The fiber laser module also includes: a control unit, which is used to adjust the parameters of the laser generated by the fiber laser to meet the requirements of different measurement needs for the laser tool 1 to output the laser, and can also control the fiber laser to turn on or off. The laser tool system also includes a power supply for powering the laser tool 1.

[0044] In a preferred implementation of this embodiment, the fiber laser module is located outside the housing 11 of the laser tool 1. The fiber laser module can be installed at any position outside the housing 11 of the laser tool 1, and can be arranged at a suitable position according to the layout of the product, which will not be described in detail in the present utility model. On the basis of the aforementioned components, since the laser diode is replaced by a fiber laser, the laser generated by the fiber laser can be transmitted to the laser tool 1 through the optical fiber 3 and the optical module 4 without affecting the laser quality, making it possible to set the fiber laser module outside the housing 11 of the laser tool 1. Thereby further, the high temperature generated by the power supply in the fiber laser module will not accumulate inside the housing of the laser tool 1, and there will be no heat dissipation problem in the housing of the laser tool 1, and there is no need to set up a complex thermal management device, which solves the problem of low heat dissipation efficiency caused by the traditional laser diode as an emission source that must be installed inside the housing of the laser tool 1, and at the same time solves the difficulty of thermal management of the emission source; thus, the heat dissipation management can be further simplified and the cost can be further reduced.

[0045] Furthermore, since the heat dissipation problem caused by the power increase is solved, the power supply of the fiber laser can be further improved, so that the brightness of the laser it produces or the receiving distance using the matching receiver will increase, exceeding that of competing products and greatly improving industry competitiveness.

[0046] In some more preferred solutions, the laser tool system further comprises: a mounting groove provided inside the housing 11 or outside the housing 11, and the optical fiber 3 is installed in the mounting groove. In a preferred embodiment, the mounting groove is provided inside the housing 11, so that the mounting groove combined with the housing 11 can better protect the optical fiber 3 which is easy to break, and improve the service life of the optical fiber 3.

[0047] The laser tool system further comprises: an optical fiber 3 fixing assembly, which is used to fix the optical fiber 3 into a coil shape, so as to prevent the optical fiber 3 from being entangled with each other and broken during use.

[0048] In addition to the structure provided by the utility model, when the laser diode is replaced by the fiber laser, there are still some electronic circuits in the laser tool system that need to be adaptively adjusted to meet the output power or frequency of the fiber module, so as to achieve different functions. Because the conversion efficiency of the optical fiber is low, more power supplies that can meet the requirements are required, but these are outside the structure itself and are not within the scope of emphasis of the utility model; and these electronic circuits are obvious to those skilled in the art according to their needs, so the utility model will not be repeated here.

[0049] The utility model uses a fiber laser as the emission source, so that laser tools such as laser levelers, laser rangefinders, and laser levelers not only have a great improvement in the quality of laser output, but also have unexpectedly improved their performances as the laser quality is improved. At the same time, the circuit debugging structure, optical debugging components, and thermal management equipment of the laser quality inside the laser tool system are simplified, making the laser tool more lightweight while improving its performance.

[0050] Furthermore, compared with the limitations of laser diodes in the prior art, the technical solution provided by the utility model can set the fiber laser module outside the laser tool housing, greatly improving the heat dissipation efficiency. And because there is no need to consider the heat dissipation problem caused by excessive power, the power limitation is broken, so that the working power of the fiber laser module can be further improved, the laser quality can be further improved, and the performance of the laser tool is naturally improved.

[0051] It should be noted that the embodiments of the present invention have better practicability and do not impose any form of limitation on the present invention. Any technician familiar with the field may use the technical content disclosed above to change or modify it into an equivalent effective embodiment. However, any modification or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
