Description

Technical Field

[0001] This invention relates to the field of solid-state lasers, specifically a temperature control device for a high-power solid-state laser. Background Technology

[0002] With the development of modern technology, the technology of fixed lasers has become more and more mature and has been gradually put into some scientific research projects.

[0003] Solid-state lasers are lasers that use solid-state laser materials as their working medium. Solid-state lasers are characterized by their small size, ease of use, and high output power. Because solid-state lasers have very high power, they generate a lot of heat during operation, causing the device temperature to rise. Therefore, the temperature control device in a high-power solid-state laser is very important. It can cool down the solid-state laser when the temperature is too high. The temperature control device is installed inside the solid-state laser and dissipates heat and cools down the device through a heat sink that contacts the working device.

[0004] However, the temperature control device of existing high-power solid-state lasers is complexly connected to the internal structure of the fixed laser housing. Since the temperature control device needs to be disassembled and repaired during the maintenance and repair of high-power fixed lasers, each disassembly and repair requires a certain amount of time, resulting in very low maintenance efficiency. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, the temperature control device of existing high-power solid-state lasers is complexly connected to the internal structure of the fixed laser housing. Since the temperature control device needs to be disassembled and repaired during the maintenance and repair of high-power fixed lasers, each disassembly and repair requires a certain amount of time, resulting in very low maintenance efficiency. This invention proposes a temperature control device for high-power solid-state lasers.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The high-power solid-state laser temperature control device of the present invention includes a housing, a support column fixedly connected to the four corners of the bottom end of the housing, a first connecting plate fixedly connected to the four corners of the top end of the housing, a top cover provided at the top end of the housing, a second connecting plate fixedly connected to the four corners of the outer side of the top cover, screws passing through the first and second connecting plates, bolts threaded to the outer side of the bottom end of the screws, a laser head fixedly connected to one side of the housing, a working device fixedly connected inside the housing, and a fixing mechanism provided inside the housing;

[0007] The fixing mechanism includes a rotating groove, which is located inside the housing on the side away from the working device. Screws are rotatably connected to both ends inside the rotating groove. A rotating block is provided on the outside of the housing. The rotating block is fixedly connected to a screw through the housing. A movable block is threadedly connected to the outside of the screw. A movable plate is fixedly connected to the outside of the movable block.

[0008] Preferably, the threads at both ends of the screw are opposite, and two sets of fixing rods are fixedly connected to one side of the movable plate.

[0009] Preferably, a temperature control device is provided inside the housing, and the temperature control device has two sets of fixing holes on both sides near the screw, and the fixing rod is inserted into the fixing holes.

[0010] Preferably, the temperature control device has two sets of telescopic holes on both sides. A hollow column is fixedly connected to one end of the telescopic hole, and a telescopic rod passes through the inside of the telescopic hole. One end of the telescopic rod is fixedly connected to a temperature plate on the outside of the telescopic hole. The temperature plate is pulled to fit tightly against the working device. A baffle is fixedly connected to one end of the telescopic rod in the telescopic hole.

[0011] Preferably, the size of the telescopic rod is adapted to the size of the hollow part of the hollow column, and the size of the baffle is smaller than the size of the hollow part of the hollow column.

[0012] Preferably, a spring is sleeved on the outside of the telescopic rod, and the two ends of the spring are fixedly connected to the baffle and the hollow column.

[0013] The advantages of this invention are:

[0014] 1. This invention, through the structural design of the fixing mechanism, enables the temperature control device to be fixed by rotating the rotating block to move the fixing rod into the fixing hole when the temperature control device is placed inside the housing. This solves the problem that the connection between the temperature control device and the inside of the fixed laser housing of existing high-power solid-state lasers is complicated. Because the temperature control device needs to be disassembled and repaired during the maintenance and repair of high-power fixed lasers, each disassembly and repair requires a certain amount of time, resulting in very low maintenance efficiency.

[0015] 2. Through the structural design of the temperature plate, telescopic rod, and spring, this invention enables the temperature plate to fit tightly against the working device via the telescopic rod and spring, achieving effective cooling. This solves the problem of insufficient heat dissipation caused by the temperature plate not fitting tightly against the working device at low temperatures, resulting in an increase in the temperature of the working device.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0026] Please see Figure 1 - Figure 6 As shown, a high-power solid-state laser temperature control device includes a housing 1, with support columns 2 fixedly connected to the four corners of the bottom end of the housing 1, and first connecting plates 3 fixedly connected to the four corners of the top end of the housing 1. A top cover 4 is provided on the top end of the housing 1, and second connecting plates 5 are fixedly connected to the four corners of the outer side of the top cover 4. Screws 6 pass through the first connecting plates 3 and the second connecting plates 5, and bolts 7 are threaded to the outer side of the bottom end of the screws 6. A laser head 8 is fixedly connected to one side of the housing 1, and a working device 9 is fixedly connected inside the housing 1. A fixing mechanism is provided inside the housing 1.

[0027] The fixing mechanism includes a rotating groove 10, which is located inside the housing 1 on the side away from the working device 9. Both ends of the rotating groove 10 are rotatably connected to screws 11. A rotating block 12 is provided on the outside of the housing 1. The rotating block 12 is fixedly connected to a screw 11 through the housing 1. A moving block 13 is threadedly connected to the outside of the screw 11. A moving plate 14 is fixedly connected to the outside of the moving block 13.

[0028] During operation, the temperature control device of the existing high-power solid-state laser is complexly connected to the internal structure of the fixed laser housing 1. Since the temperature control device needs to be disassembled and repaired during the maintenance and repair of the high-power fixed laser, each disassembly and repair requires a certain amount of time, resulting in very low maintenance efficiency. The top cover 4 is placed on the top of the housing 1, the first connecting plate 3 and the second connecting plate 5 are aligned, and the screw 6 is inserted through the first connecting plate 3 and the second connecting plate 5. The bolt 7 is threaded to the bottom of the screw 6 to complete the fixation of the top cover 4. The top cover 4 can be removed by removing the bolt 7 and the screw 6. When it is necessary to remove the temperature control device 16, the rotating block 12 drives the screw 11 to rotate. The rotation of the screw 11 will drive the moving block 13 and the moving plate 14 to move towards both ends of the screw 11.

[0029] The screw 11 has opposite threads at both ends, and two sets of fixing rods 15 are fixedly connected to one side of the movable plate 14.

[0030] During operation, the threads at both ends of the screw 11 are opposite, so when the screw 11 rotates, the moving block 13 and the moving plate 14 can move towards each other simultaneously.

[0031] The housing 1 is equipped with a temperature control device 16. The temperature control device 16 has two sets of fixing holes 17 on both sides near the screw 11. The fixing rod 15 is inserted into the fixing holes 17.

[0032] During operation, the fixing rod 15 can be inserted into the fixing hole 17 to fix the temperature control device 16, and the temperature control device 16 can be disassembled by removing the fixing rod 15 from the fixing hole 17.

[0033] The temperature control device 16 has two sets of telescopic holes 18 on both sides. A hollow column 19 is fixedly connected to one end of the telescopic hole 18. A telescopic rod 20 passes through the inside of the telescopic hole 18. One end of the telescopic rod 20 is fixedly connected to the temperature plate 21 on the outside of the telescopic hole 18. A baffle 22 is fixedly connected to one end of the telescopic rod 20 in the telescopic hole 18.

[0034] During operation, the low-temperature temperature plate 21 does not fit tightly against the working device 9, resulting in insufficient heat dissipation and causing the temperature of the working device 9 to rise. The two sets of temperature plates 21 are stretched to both ends and placed on both sides of the working device 9. The rotating block 12 is rotated in the opposite direction to move the fixing rod 15 into the fixing hole 17 to complete the fixing of the temperature control device 16. The temperature plates 21, which were originally on both sides of the working device 9, compress the spring 23 through the telescopic rod 20. When the temperature plate 21 is not under force, the compressed spring 23 pulls the baffle 22 and the telescopic rod 20 into the telescopic hole 18, and at the same time pulls the temperature plate 21 to fit tightly against the working device 9.

[0035] The size of the telescopic rod 20 is adapted to the size of the hollow part of the hollow column 19, and the size of the baffle 22 is smaller than the size of the hollow part of the hollow column 19;

[0036] During operation, the size of the telescopic rod 20 is matched with the size of the hollow part of the hollow column 19, allowing the telescopic rod 20 to slide normally in the telescopic groove. The size of the baffle 22 is smaller than the size of the hollow part of the hollow column 19, which can prevent the telescopic rod 20 from leaving the telescopic groove.

[0037] A spring 23 is sleeved on the outside of the telescopic rod 20, and the two ends of the spring 23 are fixedly connected to the baffle 22 and the hollow column 19.

[0038] During operation, the spring 23 allows the temperature plates 21 on both sides of the working device 9 to adhere tightly to the working device 9 under the tension of the spring 23 without external force. Example 2

[0039] Please see Figure 7 As shown in the first embodiment, as another implementation of the present invention, a sponge ring 100 is fixedly connected to the outer side of the rotating block 12;

[0040] When in operation, the outer side of the rotating block 12 has many sharp edges, which may cut the fingers of the operator when rotating it. The sponge ring 100 can prevent the hand from being cut.

[0041] Working principle: Place the top cover 4 on top of the housing 1, align the first connecting plate 3 and the second connecting plate 5, then insert the screw 6 through the inside of the first connecting plate 3 and the second connecting plate 5, and thread the bolt 7 onto the bottom of the screw 6 to complete the fixing of the top cover 4. Removing the bolt 7 and screw 6 allows the top cover 4 to be disassembled. When it is necessary to disassemble the temperature control device 16, rotate the rotating block 12 to drive the screw 11 to rotate. The rotation of the screw 11 will drive the moving block 13 and the moving plate 14 to move towards both ends of the screw 11. At the same time, the two sets of fixing rods 15 on one side of the moving plate 14 disengage from the fixing holes 17. At this time, the temperature control device 16 can be disassembled. After the maintenance is completed or the new temperature control device 16 is replaced, the new temperature control device 16 is placed between the two sets of moving plates 14, and the two sets of temperature plates 21 are stretched to both ends and placed on both sides of the working device 9. The rotating block 12 is rotated in the opposite direction to move the fixing rod 15 into the fixing hole 17 to complete the fixing of the temperature control device 16, and the temperature plates 21 are released. The temperature plates 21 that were originally on both sides of the working device 9 are compressed by the spring 23 through the telescopic rod 20. When the temperature plates 21 are not under force, the compressed spring 23 pulls the baffle 22 and the telescopic rod 20 into the telescopic hole 18, and at the same time pulls the temperature plates 21 to be close to the working device 9.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
