Description

Technical Field

[0001] This invention relates to the field of laser technology, and in particular to a device for applying silicone grease to a fiber laser. Background Technology

[0002] Currently, the photoelectric efficiency of industrial pump sources is around 50%, with nearly half dissipated as heat. Therefore, pump sources require good heat dissipation during operation. The mainstream usage environment involves mounting the pump source on a water-cooled plate or air-cooled heatsink to maintain the LED chip's operating temperature below 55°C. Typically, a layer of thermal grease is applied between the pump source and the cooling plate to fill the gap and improve heat conduction. The thermal grease must be thin, uniform, and free of voids to achieve optimal heat dissipation, making the grease itself crucial. Currently, there are two main methods for applying thermal grease. The first method involves directly applying the grease to the surface of the water-cooled plate before applying another layer. This method cannot achieve the required grease thickness based on actual usage requirements to ensure proper adhesion between the product and the water-cooled plate and achieve heat dissipation. Meanwhile, the lack of control over the areas where thermal paste is applied leads to a certain amount of wasted thermal paste. Another issue is that a certain thickness of adhesive tape is applied to the water-cooling plate before thermal paste is applied. The thickness of the applied thermal paste is mainly controlled by stacking the tape. During the stacking process, unevenness and air bubbles can easily occur when the tapes are attached, resulting in poor consistency in tape thickness at different locations, which fails to achieve proper adhesion between the product and the water-cooling plate. Furthermore, the need to stack the tape before applying thermal paste also affects the efficiency of the thermal paste application. Summary of the Invention

Detailed Implementation

[0013] 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.

[0014] Reference Figures 1 to 10 A device for applying silicone grease to a fiber laser, comprising: The outer frame 10 has two first cavities 101 and two cavities 102 respectively. Two inner frames 2 are slidably mounted on the outer frame 10, and a thin sheet 201 is detachably mounted on the inner frame 2; The clamping device includes a first pull rope 3, two inclined rods 4, a movable plate 5, a clamping plate 6, a crossbar 7, a pressing rod 8, a first spring 9, and a buffer device. The inclined rods 4 are disposed in the first cavity 101. The movable plates 5 can slide on the inclined rods 4. The first pull rope 3 connects the two movable plates 5. The clamping plate 6 is slidably disposed on the movable plates 5. When the clamping plate 6 is subjected to force and moves, it will squeeze the buffer device. The bottom of the crossbar 7 is provided with a through groove 701. The pressing rod 8 is slidably disposed on the outer frame 10 and one end of it is rotatably connected to the crossbar 7. The first spring 9 is sleeved on the pressing rod 8. A fixing device is used to fix the pressing rod 8 after it moves downward and the inner frame 2 after it moves. In this invention, based on the required silicone grease coating thickness for the pump source, a thin sheet 201 of appropriate thickness is selected. The device is placed on a water-cooled plate, and the pressing rod 8 is pressed down to move the crossbar 7 downward. The crossbar 7 moves the first pull rope 3 downward, which in turn pulls the two moving plates 5 on the inclined rod 4, causing the two moving plates 5 to move closer to the side of the water-cooled plate. The clamping plate 6 is tightly attached to the side of the water-cooled plate and squeezes the buffer device. The fixing device first fixes the pressing rod 8 after it moves downward, so that the outer frame 10 is fixed on the water-cooled plate, so that the two thin sheets 201 can remain parallel and will not move during the subsequent coating process. The two inner frames 2 can move on the outer frame 10. Based on the required silicone grease coating size for the pump source, the corresponding position of the thin sheet 201 is selected, and the fixing device then fixes the moved inner frame 2. After the silicone grease is taken out, it is placed at the position to be coated. The silicone grease is then coated with a scraper along a direction parallel to the thin sheet 201. After the silicone grease is coated, the fixing device is released, and the moving plate 5 and the pressing rod 8 return to their original positions. The device is removed to expose the coated position, thus completing the entire silicone grease coating process. Specifically, the pressing rod 8 is T-shaped, and its bottom is provided with a T-shaped rotating part, which is rotatably connected to the crossbar 7; the outer frame 10 is provided with a long groove that communicates with the first cavity 101 and the second cavity 102, so that the moving plate 5 and the column 202 can move.

[0015] As a preferred embodiment of the present invention, it may also have the following additional technical features: In this embodiment, the movable plate 5 has a placement groove 501; the buffer device includes a T-shaped connecting rod 11 and a second spring 12. The clamping plate 6 is disposed within the placement groove 501. One end of the connecting rod 11 is disposed on the movable plate 5 and connected to the clamping plate 6. The second spring 12 is sleeved on the connecting rod 11. After the clamping plate 6 contacts the side of the water-cooled plate, it will move within the placement groove 501 and compress the second spring 12. When the pressing rod 8 is released, the first pull rope 3 is released, and the movable plate 5 slides back to its original position on the inclined rod 4. The second spring 12 exerts a force on the clamping plate 6 to return it to its original position. This structure can adapt to water-cooled plates of different sizes, improving practicality.

[0016] In this embodiment, the inner frame 2 is provided with two columns 202, one end of which extends into the second cavity 102 and is provided with a rack; the fixing device includes a clamping rod 13, an arc plate 14, a limiting plate 15, a triggering device and a driving device. The clamping rod 13 is provided on the pressing rod 8. The arc plate 14 is provided with two baffles 141 and several clamping plates 142. The arc plate 14 is provided in the first cavity 101. When the clamping plate 6 moves on the moving plate 5 to clamp the water-cooling plate, the triggering device works to make the pressing rod 8 rotate relative to the crossbar 7. The bottom of the limiting plate 15 is provided with several protrusions 151. The driving device is used to drive the limiting plate 15 to move up and down in the second cavity 102. When the pressing rod 8 presses down and compresses the first spring 9, and the clamping plate 6 clamps the water-cooling plate, the triggering device works, allowing the pressing rod 8 to rotate. Rotating the pressing rod 8 drives the locking rod 13 to rotate, causing it to fit tightly between the two locking plates 142, thus fixing the pressing rod 8. After the two inner frames 2 are adjusted to the desired position, the driving device works to drive the limiting plate 15 downwards, causing its protrusion 151 to engage with the rack on the column 202, thereby fixing the column 202 and preventing the inner frames 2 from moving. Specifically, the two side walls of the second cavity 102 are provided with sliding grooves, and the protrusion 151 has sliding rods on both sides that are adapted to the sliding grooves.

[0017] In this embodiment, the first cavity 101 has several sliding grooves on its upper and lower walls, the clamping plate 6 has a sloping side, and the pressing rod 8 has a slot 801. The triggering device includes a T-shaped push rod 16, several third springs 17, a pull plate 18, a second pull rope 19, a fourth spring 20, a base 21, and a plug rod 22. The push rod 16 is mounted on the moving plate 5 and a fifth spring 161 is sleeved on it. The third springs 17 are sleeved on the push rod 16. The pull plate 18 has several sliding rods 181 at its upper and lower ends. The sliding rods 181 can slide in the sliding groove. The third springs 17 are located in the sliding groove. The base 21 has a cavity 211. One end of the plug rod 22 can slide in the cavity 211. The fourth spring 20 is located in the cavity 211. The second pull rope 19 connects the pull plate 18 and the plug rod 22. After the pressing rod 8 is pressed down, during the process of clamping the water-cooled plate by the clamping plate 6, the inclined surface on one side of the clamping plate 6 will push the push rod 16 to move. The push rod 16 pushes the pull plate 18 to move, and the slide rod 181 squeezes the third spring 17. The movement of the pull plate 18 will pull the insertion rod 22 to move in the cavity 211 and squeeze the fourth spring 20. One end of the insertion rod 22 will disengage from the slot 801, and the pressing rod 8 can then rotate to ensure that the clamping plate 6 clamps the water-cooled plate. After the coating is completed, the pressing rod 8 is rotated in the opposite direction to make the clamping rod 13 disengage from the two clamping plates 142. The pressing rod 8 returns to its original position, and the pull plate 18 returns to its original position.

[0018] In this embodiment, the driving device includes two third pull ropes 23, a rotating rod 24, a weight plate 25, and a swing plate 26. The rotating rod 24 is rotatably mounted on the wall of the second cavity 102. The weight plate 25 and the swing plate 26 are both mounted on the rotating rod 24. The third pull rope 23 connects the pressing rod 8 and the weight plate 25. After the two inner frames 2 are adjusted to the desired position, the pressing rod 8 is rotated, and the pressing rod 8 retracts the third pull rope 23. The third pull rope 23 pulls the weight plate 25, which in turn causes the rotating rod 24 to rotate. The swing plate 26 rotates with the rotating rod 24, and the limiting plate 15 moves downward. Its protrusion 151 engages with the rack on the column 202, thereby fixing the column 202. When the pressing rod 8 rotates in the opposite direction, the third pull rope 23 is released. The weight of the weight plate 25 itself causes the rotating rod 24 to rotate in the opposite direction. The swing plate 26 rotates in the opposite direction, causing the limiting plate 15 to move upward. Its protrusion 151 disengages from the rack on the column 202. Specifically, the upper and lower ends of the locking rod 13 are equipped with sealing gaskets to ensure tight contact with the two locking plates 142, increasing friction. This prevents the weight plate 25 from pulling the third pull rope 23 when the locking rod 13 is not disengaged from the two locking plates 142.

[0019] In this embodiment, both the inner frame 2 and the sheet 201 are U-shaped, and locking plates 203 are detachably provided on both sides of the inner frame 2. Sheets 201 of different thicknesses are replaced according to the required silicone grease coating thickness of the pump source. Specifically, the locking plates 203 are connected to the inner frame 2 by bolts.
