Abstract
Description
Technical Field
[0001] This utility model relates to a self-cleaning rubber roller tool for applying silicone grease to IGBTs, belonging to the technical field of rubber roller tools. Background Technology
[0002] The advantages of using a rubber roller to apply silicone grease include: precise control over the thickness and distribution of the grease, avoiding uneven thickness or overflow problems caused by traditional scrapers or manual application; effective removal of air bubbles during the rolling process, ensuring a tight fit between the grease and the heatsink or chip surface, improving thermal conductivity; the flexibility of the rubber material allows it to adapt to different surface curvatures, making it suitable for various electronic components such as CPUs and GPUs; and it is simple and quick to operate, reducing errors from manual application and improving production efficiency.
[0003] However, when using the roller, some silicone grease usually adheres to its surface. If it is not removed quickly, the coating effect of the rubber roller will decrease. If it is cleaned after each use, the frequency of use by the user will be reduced, thus reducing the coating efficiency.
[0004] Therefore, it is urgent to improve the rubber roller tools to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a self-cleaning rubber roller tool for applying silicone grease to IGBTs. When the operator uses it, the scraper and the brush roller come into contact, which can scrape off the silicone grease adhering to the brush roller, thereby achieving a self-cleaning effect and preventing excessive accumulation of silicone grease on the brush roller, which would reduce the cleaning effect.
[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a cleaning frame and a brush roller rotatably disposed inside the cleaning frame, wherein a scraper connected to the cleaning frame is provided on one side of the brush roller, and one side of the scraper abuts against the surface of the brush roller;
[0007] Two limiting bolts are threadedly connected to one side of the cleaning rack. Each of the two limiting bolts is rotatably connected to a rotating seat. Each of the two rotating seats is rotatably connected to the scraper on one side. The limiting bolts are used to limit the rotation of the scraper.
[0008] Preferably, the scraper is fixedly provided with two fixing rods on the side near the rotating seat, and the rotating seat is fixedly provided with two connecting rods that are rotatably connected to the two ends of the fixing rods on the side near the scraper.
[0009] Preferably, the rotating seat has a groove that allows the limiting bolt to rotate.
[0010] Preferably, the scraper has a top groove on the side near the rotating seat, and one end of the limiting bolt abuts against the inside of the top groove.
[0011] Preferably, two sets of second fastening nuts are provided on the two limiting bolts, with each set consisting of two second fastening nuts and threadedly connected to the limiting bolts. The two second fastening nuts in each set are located on the inner and outer sides of the limiting bolts, respectively.
[0012] Preferably, a locking rod is inserted into the inner side of the cleaning frame, and the brush roller is rotatably connected to the cleaning frame through the locking rod.
[0013] Preferably, both ends of the pin are threadedly connected to a first fastening nut.
[0014] This utility model has at least the following beneficial effects:
[0015] When the operator uses it, the scraper comes into contact with the brush roller, which can scrape off the silicone grease attached to the brush roller, thereby achieving a self-cleaning effect and preventing excessive accumulation of silicone grease on the brush roller, which would reduce the cleaning effect.
[0016] When the angle of the scraper needs to be adjusted, the operator turns the limiting bolt to gradually move it away from the scraper. When the scraper is no longer under the force of the limiting bolt, the operator can manually adjust the angle of the scraper. After adjusting to the appropriate angle, the operator turns the limiting bolt in the opposite direction so that one end of the limiting bolt abuts against the top groove, so that the scraper will not rotate again when it is under force.

Detailed Implementation
[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0024] Examples, such as Figures 1-4 As shown, a self-cleaning rubber roller tool for applying silicone grease to IGBTs includes a cleaning frame 1 and a brush roller 2 rotatably disposed inside the cleaning frame 1. A scraper 5 connected to the cleaning frame 1 is provided on one side of the brush roller 2. One side of the scraper 5 abuts against the surface of the brush roller 2. When the operator uses it, the scraper 5 abuts against the brush roller 2, which can scrape off the silicone grease adhering to the brush roller 2, thereby achieving a self-cleaning effect and preventing excessive accumulation of silicone grease on the brush roller 2, which would reduce the cleaning effect.
[0025] Two limiting bolts 6 are threadedly connected to one side of the cleaning frame 1. A rotating seat 8 is rotatably connected to each of the two limiting bolts 6. One side of each rotating seat 8 is rotatably connected to the scraper 5. The limiting bolts 6 are used to limit the rotation of the scraper 5. A top groove 10 is opened on the side of the scraper 5 near the rotating seat 8. One end of the limiting bolt 6 abuts against the inside of the top groove 10. The rotating seat 8 can limit the scraper 5 inside the cleaning frame 1 through the limiting bolts 6, so that the scraper 5 can meet the above-mentioned cleaning requirements of the brush roller 2.
[0026] When it is necessary to clean the silicone grease on the scraper 5, the operator tightens the limiting bolt 6 to move the limiting bolt 6 away from the brush roller 2. Then, by using the sliding of the rotating seat 8 and the limiting bolt 6, the scraper 5 is pulled away from the brush roller 2, thereby increasing the distance between the scraper 5 and the brush roller 2 so that the operator can clean the silicone grease on the scraper 5.
[0027] When the angle of scraper 5 needs to be adjusted, the operator turns the limiting bolt 6 to gradually move the limiting bolt 6 away from scraper 5. When scraper 5 is no longer under the force of limiting bolt 6, the operator can manually adjust the angle of scraper 5. After adjusting to the appropriate angle, the operator turns the limiting bolt 6 in the opposite direction so that one end of the limiting bolt 6 abuts against the top groove 10, so that scraper 5 will not rotate again after being subjected to force.
[0028] like Figures 1-4As shown, furthermore, two fixed rods 11 are fixedly installed on the side of the scraper 5 near the rotating seat 8, and two connecting rods 12 are fixedly installed on the side of the rotating seat 8 near the scraper 5, which are rotatably connected to the two ends of the fixed rods 11. The rotating seat 8 is provided with a rotating groove 9 to accommodate the rotation of the limiting bolt 6. The fixed rods 11 and the connecting rods 12 are connected by insertion and rotation, which is a relatively mature technology. Thus, the rotating seat 8 can be rotatably connected to the scraper 5 through the cooperation of the two. The opening of the rotating groove 9 can play an auxiliary role in the connection between the rotating seat 8 and the limiting bolt 6 when the limiting bolt 6 is screwed into the cleaning frame 1, so as to avoid the rotating seat 8 from obstructing the rotation of the limiting bolt 6.
[0029] like Figure 1 , Figure 3 As shown, furthermore, two sets of second fastening nuts 7 are provided on the two limiting bolts 6. Each set of two second fastening nuts 7 is a group and is threadedly connected to the limiting bolts 6. The two second fastening nuts 7 in each group are located on the inner and outer sides of the limiting bolts 6, respectively. By setting two second fastening nuts 7 on the inner and outer sides of the cleaning rack 1, after the limiting bolts 6 are connected to the cleaning rack 1, the staff can tighten the second fastening nuts 7 so that each set of two second fastening nuts 7 on the limiting bolts 6 can move towards the surface of the cleaning rack 1 and even fit together, thereby strengthening the connection between the limiting bolts 6 and the cleaning rack 1.
[0030] like Figure 1 As shown, further, a locking rod 3 is inserted into the inner side of the cleaning frame 1. The brush roller 2 is rotatably connected to the cleaning frame 1 through the locking rod 3. Both ends of the locking rod 3 are threadedly connected with a first fastening nut 4. The setting of the locking rod 3 not only allows the brush roller 2 to rotate with the cleaning frame 1, but also allows the brush roller 2 to be disassembled from the cleaning frame 1 after the locking rod 3 is removed, so as to facilitate the disassembly of the scraper 5 from the cleaning frame 1. The locking rod 3 can be connected and fixed to the cleaning frame 1 through the first fastening nut 4, thereby stabilizing the connection between the brush roller 2 and the cleaning frame 1.
[0031] When it is necessary to disassemble the scraper 5, firstly, the brush roller 2 is disassembled from the cleaning frame 1. Then, the operator turns the limiting bolt 6 so that the limiting bolt 6 can gradually move to the inside of the cleaning frame 1 until it is sorted. In this way, the scraper 5 can be separated from the cleaning frame 1.
[0032] In this embodiment, as Figures 1-4 As shown, the principle of a self-cleaning rubber roller tool for applying IGBT silicone grease provided in this embodiment is as follows: A scraper 5 connected to the cleaning frame 1 is provided on one side of the brush roller 2. One side of the scraper 5 abuts against the surface of the brush roller 2. When the operator uses it, the scraper 5 abuts against the brush roller 2, which can scrape off the silicone grease attached to the brush roller 2, thereby achieving a self-cleaning effect and avoiding excessive accumulation of silicone grease on the brush roller 2, which would reduce the cleaning effect.
[0033] When it is necessary to clean the silicone grease on the scraper 5, the operator tightens the limiting bolt 6 to move the limiting bolt 6 away from the brush roller 2. Then, by using the sliding of the rotating seat 8 and the limiting bolt 6, the scraper 5 is pulled away from the brush roller 2, thereby increasing the distance between the scraper 5 and the brush roller 2 so that the operator can clean the silicone grease on the scraper 5.
[0034] When the angle of scraper 5 needs to be adjusted, the operator turns the limiting bolt 6 to gradually move the limiting bolt 6 away from scraper 5. When scraper 5 is no longer under the force of limiting bolt 6, the operator can manually adjust the angle of scraper 5. After adjusting to the appropriate angle, the operator turns the limiting bolt 6 in the opposite direction so that one end of the limiting bolt 6 abuts against the top groove 10, so that scraper 5 will not rotate again after being subjected to force.
