Description

Technical Field

[0001] This invention belongs to the field of laser emitter technology, specifically a rotatable laser emitter. Background Technology

[0002] A laser emitter can emit a very thin, concentrated beam of light. The working principle of a laser emitter is to use the light generated by a laser diode, which is guided and amplified by some optical elements to finally emit a laser beam. This laser beam can be used to accurately illuminate the target object and can be used for cutting, welding, marking, and so on. Laser emitters have many applications. For example, in the industrial field, they can be used to cut materials such as metals and plastics; in the scientific research field, they can be used to study the propagation and reflection of light.

[0003] Existing rotatable laser emitters have certain drawbacks in use. They typically operate by controlling the laser emitter's rotation directly through an internal drive motor. Since laser emitters are usually used for measurement, dust can easily clog the heat sinks inside the device, which are used to cool the drive motor, when the laser emitter is used for measurement in dusty construction sites. This deteriorates the working environment of the drive motor and reduces its lifespan over time, failing to meet people's needs. Utility Model Content

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1

[0026] Please see Figure 1 - Figure 4This application provides a rotatable laser emitter, including a mounting base 1, an adjustment mechanism movably mounted on the mounting base 1, and a laser emitter body 2 detachably mounted on the adjustment mechanism. The adjustment mechanism includes a rotating seat 3 detachably mounted on the upper end of the mounting base 1, a rotating seat 4 rotatably mounted on the rotating seat 3, a fixing component rotatably connected to the rotating seat 4, and a heat dissipation component mounted on the rotating seat 3. The fixing component allows for the disassembly or fixing of the laser emitter body 2, facilitating maintenance and replacement by personnel. A rotating motor 15 is internally mounted on the rotating seat 3. The heat dissipation component includes a heat-absorbing ring 18 mounted on the outer wall of the rotating motor 15, an annular heat dissipation fins 19 sleeved on the outer wall of the rotating seat 3, and several sets of heat-conducting rods 20 vertically mounted on the outer wall of the heat-absorbing ring 18. The rotating seat 3 has through holes arranged in a circular array to match the heat-conducting rods 20. The heat-absorbing ring 18 and the heat-conducting rods 20 transfer the heat generated by the rotating motor 15 to the annular heat dissipation fins 19, thereby allowing the annular heat dissipation fins 19 to diffuse the heat into the air and dissipate heat from the rotating motor 15.

[0027] As one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the rotary motor 15 generates heat when it is working. The heat-absorbing ring 18 absorbs the heat and transfers it to the heat-conducting rod 20. The heat-conducting rod 20 then transfers the heat to the annular heat dissipation fins 19, so that the annular heat dissipation fins 19 dissipate heat from the rotary motor 15.

[0028] In this utility model, the bottom end of the rotating seat 4 is provided with a rotating base plate 28 that fits against the rotating seat 3. The heat dissipation assembly includes a reinforcing block 29 movably disposed on the outside of the rotating base plate 28 and several sets of fixing members 30 detachably connected to the reinforcing block 29. A cleaning roller 31 for cleaning the annular heat dissipation fins 19 is vertically disposed on the lower end surface of the fixing member 30. The rotating base plate 28 controls the cleaning roller 31 to clean the annular heat dissipation fins 19 through the reinforcing block 29 and the fixing member 30.

[0029] In this utility model, the cleaning roller 31 has a cylindrical structure, and a rotating support rod 32 that is rotatably connected to the fixing member 30 is provided on the upper part of the cleaning roller 31.

[0030] The heat dissipation component of this utility model also includes several sets of support plates 33 arranged vertically and in a circular array on the upper end of the mounting base 1, several sets of adjusting rods 34 detachably mounted on the support plates 33, adjusting blocks rotatably connected to the adjusting rods 34, and a dust removal component 35 for cleaning the cleaning roller 31. The adjusting blocks are detachably connected to the outer surface of the dust removal component 35.

[0031] In this invention, the rotating base 3 is internally provided with a connector 16 mounted on the output shaft of the rotating motor 15. The top end of the connector 16 is detachably connected to the bottom end of the rotating base 4. The bottom end of the rotating base 4 is provided with several sets of auxiliary rollers 17 arranged in a circular array. The upper end surface of the rotating base 3 is provided with an auxiliary groove that is rolledly connected to the auxiliary rollers 17. The rotating motor 15 can control the rotating base 4 to rotate horizontally on the upper end of the rotating base 3 through the connector 16, thereby adjusting the horizontal angle of the laser emitter body 2. The auxiliary rollers 17 and the auxiliary groove work together to make the rotation of the rotating base 4 more convenient.

[0032] In one embodiment of this utility model, the rotary motor 15 is started, which drives the connecting piece 16 to rotate. The connecting piece 16 drives the rotating seat 4 to rotate on the rotating seat 3, so that the rotating seat 4 drives the auxiliary roller 17 to roll and move in the auxiliary groove.

[0033] In summary, the rotating motor 15 generates heat during operation. The heat-absorbing ring 18 absorbs the heat and transfers it to the heat-conducting rod 20. The heat-conducting rod 20 then transfers the heat to the annular heat dissipation fins 19, allowing the annular heat dissipation fins 19 to dissipate heat from the rotating motor 15. Starting the rotating motor 15 causes the connecting member 16 to rotate, which in turn causes the rotating seat 4 to rotate on the rotating seat 3. This causes the rotating seat 4 to move the auxiliary roller 17 in the auxiliary groove. The rotation of the rotating seat 4 causes the rotating base plate 28 to rotate on the rotating seat 3. The rotating base plate 28 then causes several sets of reinforcing blocks 29 to rotate, which in turn causes the reinforcing blocks 29 to rotate. The fixing part 30 rotates, which drives the rotating support rod 32 to rotate. The rotating support rod 32 drives the cleaning roller 31 to move, thereby cleaning the annular heat sink fins 19. This eliminates the need to stop the laser emitter to clean and maintain the annular heat sink fins 19. When the rotating base plate 28 drives the cleaning roller 31 to the cleaning part 35, the cleaning part 35 cleans the dust adhering to the cleaning roller 31. The adjusting rod 34 is rotated to adjust its position, causing the adjusting rod 34 to drive the cleaning part 35 to move, thereby adjusting the distance between the cleaning part 35 and the cleaning roller 31.
