Description

Technical Field

[0001] This utility model belongs to the field of laser displacement sensor technology, and specifically relates to a laser displacement sensor with a heat dissipation structure. Background Technology

[0002] A laser displacement sensor is a high-precision sensor that uses laser technology for measurement. It measures the displacement or distance of a target object by generating a laser beam and receiving its reflected light. The laser generator inside the sensor will generate a lot of heat under high temperature or long-term working conditions, and heat dissipation is usually required to ensure that the sensor works stably and reliably.

[0003] For example, Chinese patent CN217308114U discloses a protective shell body, a heat-conducting layer, heat sink fins, a heat sink box, an axial fan, and heat dissipation channels. The heat sink box is installed on the inner walls of the front and rear sides of the protective shell body. The heat-conducting layer covers the outside of the laser generator. Heat sink fins are provided on the outside of the heat-conducting layer and extend into the heat sink box. The axial fan is set inside the heat sink box. Heat dissipation channels are provided at both ends of the heat sink box. Heat dissipation holes are opened on the front and rear sides of the protective shell body.

[0004] In the aforementioned laser displacement sensor, the heat generated by the laser generator is dissipated by a fan in conjunction with heat sink fins. Although the fan can drive airflow, its heat dissipation efficiency is limited by the design of the rotation speed, airflow, and airflow path. This results in the heat generated by the laser generator not being dissipated quickly and sufficiently. Especially under long-term high-load operation, the heat accumulation phenomenon becomes more and more obvious, which may affect the performance of the laser generator and even pose an overheating risk, as the critical heat cannot be effectively dissipated in a timely manner.

One end of the first water pipe is fixedly connected to a second water pipe, one side of the second water pipe is fixedly connected to the interior of the water-cooled plate and extends into the exterior of the sensor housing, and the other ends of both the first and second water pipes are fixedly connected to a water tank. A circulating water pump is fixedly connected to one side of the first water pipe.

[0009] As a preferred technical solution, the inside of the arc groove is fixedly connected with a reinforcing block, and multiple reinforcing blocks are provided.

[0010] As a preferred technical solution, the power component includes a motor, which is fixedly connected to one end of the water tank away from the first and second water pipes. A small gear is fixedly connected to the output end of the motor, a large gear is meshed with one side of the small gear, a shaft is fixedly connected to one side of the large gear, and one side of the shaft is rotatably connected inside the water tank.

A heat dissipation fin is attached to the end of the heat-conducting layer away from the water tank, and a heat dissipation fan is provided at the end of the heat dissipation fin away from the heat-conducting layer. The heat dissipation fan is fixedly connected to the water tank.

[0012] As a preferred technical solution, a mounting base is fixedly connected inside the sensor housing, and a bracket is embedded inside the mounting base. One end of the bracket is fixedly connected to one end of the water-cooling plate.

[0013] As a preferred technical solution, a cover is attached to one end of the sensor housing, and the cover is fixedly connected to the sensor housing by fixing screws.

[0014] In summary, the present invention has the following main advantages:

[0015] First, this utility model, by attaching a water-cooling plate to the laser generator, installing a water tank on the outside of the sensor housing, installing a heat dissipation component on the water tank, and installing a circulation component between the water tank and the water-cooling plate, forms a water-cooled heat dissipation structure. Compared with the existing air-cooled heat dissipation technology, its heat dissipation effect is better, which accelerates the heat dissipation of the laser generator and ensures that the laser generator works stably under long-term high-load conditions, thus providing a reliable guarantee for the operation of the laser displacement sensor.

[0016] Secondly, this utility model, by installing a power component on the water tank, uses the power component to drive multiple agitator plates inside the water tank to rotate. The coolant enters the water tank and flows downward into the arc groove of the agitator plate, thereby stirring the coolant and moving it towards the heat dissipation component, which facilitates faster heat dissipation and ensures that the water-cooled plate efficiently cools the laser generator.

[0023] Example

[0024] refer to Figures 1 to 5This embodiment describes a laser displacement sensor with a heat dissipation structure, comprising a sensor housing 1, a laser generator 2 fixedly connected inside the sensor housing 1, a water-cooling plate 3 attached to one side of the laser generator 2, a circulation assembly 5 outside the sensor housing 1, a water tank 4 fixedly connected to one end of the sensor housing 1, one side of the circulation assembly 5 fixedly connected to one side of the water tank 4, a power assembly 9 on the side of the water tank 4 away from the circulation assembly 5, a plurality of agitator plates 6 rotatably connected inside the water tank 4, an arc groove 7 on one side of the agitator plate 6, the arc groove 7 on the agitator plate 6 approaching the heat dissipation assembly 10, and after the agitator plate 6 rotates, it can guide the coolant in the water tank 4 toward the heat dissipation assembly 10. The heat dissipation assembly 10 is fixedly connected to one side of the water tank 4. Through the improved design, the heat of the laser generator 2 can be dissipated in time, improving the heat dissipation efficiency of the laser generator 2, ensuring that it can work under high load for a long time, and avoiding the performance of the laser displacement sensor being affected.

[0025] refer to Figure 1 The circulation component 5 includes a first water pipe 51, which is fixedly connected to the sensor housing 1 and extends into the interior of the water-cooled plate 3. One end of the first water pipe 51 is fixedly connected to a second water pipe 53, and one side of the second water pipe 53 is fixedly connected to the interior of the water-cooled plate 3 and extends out of the sensor housing 1. The other ends of both the first water pipe 51 and the second water pipe 53 are fixedly connected to the water tank 4. A circulating water pump 52 is fixedly connected to one side of the first water pipe 51. By setting up the circulation component 5, the circulating water pump 52 draws out the coolant from the water tank 4. The coolant enters the second water pipe 53 inside the cooling plate from the first water pipe 51, carries away the heat, and then enters the water tank 4 from the second water pipe 53, thus achieving the function of circulating cooling.

[0026] refer to Figure 3 The arc groove 7 is fixedly connected with a reinforcing block 8, and there are multiple reinforcing blocks 8; by fixing multiple reinforcing blocks 8 in the arc groove 7, the structural strength of the stirring plate 6 can be improved, and the stirring plate 6 can easily stir the coolant.

[0027] refer to Figure 5 The power assembly 9 includes a motor 91, which is fixedly connected to the end of the water tank 4 away from the first water pipe 51 and the second water pipe 53. A small gear 92 is fixedly connected to the output end of the motor 91. A large gear 93 is meshed with one side of the small gear 92. A shaft 94 is fixedly connected to one side of the large gear 93. One side of the shaft 94 is rotatably connected inside the water tank 4. An agitator plate 6 is fixedly connected to the shaft 94. By setting up the power assembly 9, the motor 91 drives the small gear 92 to rotate, the small gear 92 drives the large gear 93 to rotate, and the large gear 93 drives the shaft 94 to rotate, so that the shaft 94 drives multiple agitator plates 6 to rotate, stirring the coolant in the water tank 4 and bringing it closer to the heat dissipation assembly 10, which facilitates the cooling of the coolant in the water tank 4.

[0028] refer to Figure 4 The heat dissipation assembly 10 includes a heat-conducting layer 101, which is fixedly connected to the end of the water tank 4 away from the motor 91. A heat dissipation fin 102 is attached to the end of the heat-conducting layer 101 away from the water tank 4. A cooling fan 103 is provided at the end of the cooling fin 102 away from the heat-conducting layer 101, and the cooling fan 103 is fixedly connected to the water tank 4. By setting up the heat dissipation assembly 10, the heat-conducting layer 101 is attached to the water tank 4, and the heat dissipation fin 102 is attached to the heat-conducting layer 101, so as to concentrate and conduct internal heat out. The cooling fan 103 is installed on the water tank 4, and the cooling fan 103 dissipates heat from the cooling fin 102, thereby dissipating heat from the coolant in the water tank 4.

[0029] refer to Figure 2 The sensor housing 1 has a mounting base 12 fixedly connected inside, and a bracket 11 is embedded inside the mounting base 12. One end of the bracket 11 is fixedly connected to one end of the water-cooled plate 3. By fixing the mounting base 12 on the sensor housing 1, the bracket 11 is installed on the water-cooled plate 3 to install the water-cooled plate 3, ensuring that the water-cooled plate 3 is attached to the laser generator 2.

[0030] refer to Figure 1 One end of the sensor housing 1 is fitted with a cover 13, which is fixedly connected to the sensor housing 1 by a fixing screw 14. The cover 13 is fixed to the sensor housing 1 by the fixing screw 14, and the inside of the sensor can be inspected by opening the cover 13.

[0031] Operating principle and advantages: The water-cooled plate 3 is installed on the heat dissipation surface of the laser generator 2, ensuring a tight fit between it and the contact surface of the laser generator 2 to reduce thermal resistance. The circulating water pump 52 operates to draw coolant from the water tank 4, allowing the coolant to enter the second water pipe 53 inside the cooling plate from the first water pipe 51, carrying away heat, and then entering the water tank 4 from the second water pipe 53. This improves the heat dissipation effect of the laser generator 2, accelerates the dissipation of heat from the laser generator 2, and provides a reliable guarantee for the operation of the laser displacement sensor. The motor 91 drives the pinion 92 to rotate. 2 drives the large gear 93 to rotate, which in turn drives the shaft 94 to rotate, causing the shaft 94 to drive multiple agitator plates 6 to rotate, thus agitating the coolant in the water tank 4. Since the heat-conducting layer 101 is attached to the water tank 4, and the heat dissipation fins 102 are attached to the heat-conducting layer 101, the internal heat is concentrated and dissipated. A cooling fan 103 is installed on the water tank 4 to dissipate heat from the heat dissipation fins 102, thereby dissipating heat from the coolant in the water tank 4 and ensuring the efficient heat dissipation effect of the water-cooled plate 3, thus providing a guarantee for the long-term high-load operation of the laser displacement sensor.
