Description

Technical Field

[0001] This utility model relates to the field of heat dissipation component pretreatment technology, and in particular to a heat dissipation component pretreatment device. Background Technology

[0002] There are many types of heat dissipation components, including but not limited to aluminum heat sinks, copper heat sinks, heat pipes, and vapor chambers. These heat dissipation components are widely used in electronic equipment, power systems, industrial machinery, automotive engines, and other fields. Copper heat sinks, as a highly efficient heat dissipation element, are widely used in various electronic devices, and their heat dissipation performance directly affects the stability and lifespan of the equipment.

[0003] In the production process of copper heat sinks, the pretreatment stage is a crucial initial step to ensure product quality. Cleaning, as a vital part of pretreatment, plays an indispensable role. During production, due to different processing techniques, the surface of the copper busbar inevitably becomes contaminated with impurities such as oil, solder scars, and oxide films. If these impurities are not thoroughly removed, they will hinder subsequent processing steps. For example, in electroplating and welding, the presence of impurities can lead to poor plating adhesion and weak welds, severely affecting product consistency and reliability. Furthermore, residual impurities will reduce the heat conduction efficiency of the copper busbar, thus weakening its heat dissipation performance and failing to meet the ever-increasing heat dissipation demands of electronic devices. While existing cleaning methods for copper heat sinks can remove some impurities to a certain extent, they cannot completely clean the copper busbar, resulting in reduced cleaning efficiency.

[0047] Reference Figure 1-6 As shown, a heat dissipation component pretreatment device, in practical applications, is used to thoroughly clean impurities on the surface of the heat dissipation copper busbar, including a rinsing mechanism 1 and a brushing mechanism 2 adapted to the rinsing mechanism 1.

[0048] The rinsing mechanism 1 is used to clean the surface of the heat sink copper busbar. Specifically, the rinsing mechanism 1 includes a cleaning tank 11, a plurality of agitators 12 disposed within the cleaning tank 11, and a plurality of rinsing pumps 13 located on the cleaning tank 11. The cleaning tank 11 has a groove-shaped structure with one end inclined. The cleaning tank 11 is filled with a cleaning solution for cleaning the heat sink copper busbar. The cleaning solution can be, but is not limited to, a brightening cleaner, a purified solution, or a mixture thereof. After the heat sink copper busbar is placed into the cleaning tank 11, the cleaning solution reacts with the surface of the heat sink copper busbar, dissolving and removing impurities (such as oxide scale and solder scars) on the surface of the heat sink copper busbar. The plurality of agitators 12 are fixedly disposed within the cleaning tank 11 and located at the bottom of the cleaning tank 11. The plurality of agitators 12 are used to agitate the cleaning solution within the cleaning tank 11, causing the cleaning solution within the cleaning tank 11 to form turbulence, thereby improving the dissolution efficiency of the cleaning solution on the surface of the heat sink copper busbar. A plurality of the flushing pumps 13 are disposed on the cleaning tank 11 at one end away from the inclined surface, and the plurality of flushing pumps 13 are fixedly connected to the cleaning tank 11. On the one hand, the flushing pumps 13 directly impact the surface of the heat dissipation copper busbar by spraying water, thereby further improving the cleaning effect. On the other hand, under the impact of the water sprayed by the flushing pumps 13, the overall flow direction of the cleaning liquid in the cleaning tank 11 is caused to flow from the end close to the flushing pumps 13 to the end away from the flushing pumps 13, thereby causing the heat dissipation copper busbar to move toward the end away from the flushing pumps 13 in the cleaning tank 11.

[0049] In this embodiment, to facilitate the transfer of the rinsed copper heat sink, a transport module 14 is also provided in the cleaning tank 11. The transport module 14 is fixedly installed on the tank wall of the cleaning tank 11. The transport module 14 is used to transfer the copper heat sink in the cleaning tank 11, and there is a gap between the transport module 14 and the bottom of the cleaning tank 11 to prevent the copper heat sink from sinking to the bottom after being put into the cleaning tank 11, causing the surface of the copper heat sink to stick to the cleaning tank 11 and preventing effective cleaning. The transport module 14 includes a support component 141 and a conveying component 142 adapted to the support component 141. The cleaning tank 11 is equipped with several rotating rollers, with gaps between adjacent rollers to ensure that the surface of the copper heat sink that contacts the rollers during movement can effectively contact the cleaning fluid for cleaning. These rollers together form the support assembly 141, which is horizontally positioned within the cleaning tank 11 to support the copper heat sink. Under the action of the flushing pump 13, the copper heat sink moves on the support assembly 141. The conveying assembly 142 is fixedly installed within the cleaning tank 11, located at one inclined end, to transfer the copper heat sink from the cleaning tank 11. The conveying component 142 may be, but is not limited to, a belt conveyor or a chain plate conveyor. In this embodiment, a chain plate conveyor is used, which consists of chain plates, a drive device, and a frame. After the heat dissipation copper busbar moves onto the chain plate, the drive device drives the chain plate to move. Under the action of friction, the heat dissipation copper busbar is transferred to the brushing mechanism 2 along with the movement of the chain plate.

[0050] Please refer to Figures 4-6 As shown in this embodiment, since a small amount of impurities and residual cleaning liquid may still adhere to the surface of the heat dissipation copper busbar after rinsing, in order to further clean the impurities on the surface of the heat dissipation copper busbar, the brushing mechanism 2 is set at one end of the rinsing mechanism 1 and is adapted to the rinsing mechanism 1. That is, after the heat dissipation copper busbar is rinsed in the rinsing mechanism 1, it is transferred to the brushing mechanism 2 to clean the residual impurities and cleaning liquid on the surface, so as to increase the cleanliness of the surface of the heat dissipation copper busbar.

[0051] Specifically, the washing mechanism 2 includes a mounting box 21, a washing module 22 disposed within the mounting box 21, and a discharge module 23 adapted to the washing module 22. The mounting box 21 is located at one end of the inclined surface of the cleaning tank 11, that is, the top of the mounting box 21 is provided with a groove in the shape of a narrow opening. The bottom end of the groove is provided with a first opening, which is a feed inlet 211. The width of the feed inlet 211 is adapted to the thickness of the heat dissipation copper busbar, so that when the heat dissipation copper busbar slides down into the groove to the feed inlet 211, it can only enter the feed inlet 211 in a vertical state. A second opening is also provided on one side of the mounting box 21, which is a discharge outlet 212. The heat dissipation copper busbar is transported to the top of the mounting box 21 by the conveying component 142. Under the action of gravity, the heat dissipation copper busbar enters the mounting box 21 through the feed inlet 211 and flows out through the discharge outlet 212.

[0052] The brushing module 22 is disposed inside the mounting box 21. The brushing module 22 is used to brush the heat dissipation copper busbar. It includes two brushing rollers 221 and a drive assembly 222 connected to the two brushing rollers 221. The two brushing rollers 221 are rotatably mounted on the box wall inside the mounting box 21, and the two brushing rollers 221 are located at the feed inlet 211 inside the mounting box 21. Their surfaces are covered with nylon fiber cloth for brushing the heat dissipation copper busbar. A gap adapted to the heat dissipation copper busbar is provided between the two brushing rollers 221. That is, when the heat dissipation copper busbar is inserted into the gap, the two brushing rollers 221 will abut against it. On the one hand, the surface of the heat dissipation copper busbar is brushed by the nylon fiber cloth on the brushing rollers 221. On the other hand, the nylon fiber cloth also has friction when brushing the heat dissipation copper busbar to clamp it. It is understandable that, since the material of the heat dissipation copper busbar has a certain degree of hardness, the clamping force of the two brush rollers 221 is far lower than the force that would cause deformation to it, so the heat dissipation copper busbar will not be deformed when it is clamped.

[0053] The drive assembly 222 is fixedly mounted on the mounting box 21 and is used to drive the two brushing rollers 221 to rotate. Specifically, the drive assembly 222 includes a gear set 2221 and a driver 2222 connected to the gear set 2221. The gear set 2221 is rotatably mounted on the mounting box 21 and fixedly connected to the two brushing rollers 221. It includes a first gear 22211, a second gear 22212 meshing with the first gear 22211, and a third gear 22213 meshing with the second gear 22212. The center of the first gear 22211 is fixedly connected to the rotating shaft of one brushing roller 221, and the center of the third gear 22213 is fixedly connected to the rotating shaft of the other brushing roller 221. The second gear 22212 is disposed between the first gear 22211 and the third gear 22213, and is connected to the first gear 22212. The first gear 22211 and the third gear 22213 are meshed together. By rotating the first gear 22211 or the third gear 22213, the two brush rollers 221 can rotate in opposite directions. That is, one brush roller 221 rotates clockwise and the other brush roller 221 rotates counterclockwise. When the two brush rollers 221 brush the heat dissipation copper busbar, the resultant force generated by the two brush rollers 221 on the heat dissipation copper busbar is directed towards the discharge port 212. When the heat dissipation copper busbar comes into contact with the brush rollers 221, the friction between the two pulls the heat dissipation copper busbar into the gap between the two brush rollers 221. The driver 2222 is fixedly mounted on the mounting box 21 and is used to drive the gear set 2221 to rotate. Starting the driver 2222 can make the two conveying brush rollers 221 rotate. For example, the driver 2222 is a motor, which is composed of components such as stator, rotor and drive shaft. The drive shaft of the motor is fixedly connected to the first gear 22211. By starting the motor, the first gear 22211 can be driven to rotate, thereby causing the gear set 2221 to rotate, which in turn drives the two brush rollers 221 to rotate in opposite directions at the same time.

[0054] In this embodiment, due to the weight of the heat dissipation copper busbar, it may fall between the two brushing rollers 221 during brushing, resulting in insufficient brushing. To extend the brushing time, the discharge module 23 is disposed inside the mounting box 21 and located at the discharge port 212. The discharge module 23 is adapted to the brushing module 22, that is, during brushing, the discharge module 23 is used to support the heat dissipation copper busbar to prevent it from falling through the gap. It includes a receiving plate 231 and two support components 232 connected to the receiving plate 231. The receiving plate 231 is movably disposed inside the mounting box 21 and located below the brushing rollers 221. One end of the receiving plate 231 away from the discharge port 212 is hinged to the mounting box 21 via several hinges. The receiving plate 231 is used to abut against the heat dissipation copper busbar, providing support. Two support components 232 are movably disposed at the bottom end of the receiving plate 231 and movably connected to one end of the receiving plate 231 near the discharge port 212. The support components 232 provide support for the receiving plate 231, ensuring that the receiving plate 231 is horizontal within the mounting box 21 without external force, thus shielding the space below the washing roller 221. For the purpose of describing the support components 232, only one support component 232 is used here. The support component 232 includes an elastic element 2321 and a movable element 2322 connected to the elastic element 2321. The top end of the elastic element 2321 is rotatably connected to the receiving plate 231, and the elastic force of the elastic element 2321 is adapted to the weight of the heat dissipation copper busbar. The elastic element 2321 is a spring rod. For example, the spring rod consists of a telescopic rod and a spring disposed in the telescopic rod. When the heat dissipation copper busbar falls from the gap onto the receiving plate 231, the receiving plate 231 is always in contact with the heat dissipation copper busbar under the action of the spring rod to prevent the heat dissipation copper busbar from falling off.

[0055] When the two brushing rollers 221 brush the heat dissipation copper busbar, they exert a downward force on it. The resultant force of this force and the weight of the heat dissipation copper busbar compresses the elastic element 2321, causing the support plate to rotate around the hinge point between it and the mounting box 21. Under the action of the two brushing rollers 221, the heat dissipation copper busbar continues to move toward the discharge port 212. The end of the support plate near the discharge port 212 moves from the top end of the discharge port 212 to the bottom end of the discharge port 212, causing the support plate to tilt and connect the space below the brushing rollers 221 with the discharge port 212. After the heat dissipation copper busbar is brushed, one end of the heat dissipation copper busbar enters the gap between the two brushing rollers 221 and the other end of the heat dissipation copper busbar leaves through the gap between the two brushing rollers 221 and flows out through the discharge port 212 to the next process.

[0056] When the receiving plate 231 rotates, the elastic element 2321 moves. The moving element 2322 includes a slide rail fixedly installed at the bottom of the mounting box 21 and a slider movably installed on the slide rail. That is, the slider can move along the path of the slide rail. The bottom end of the elastic element 2321 is fixedly connected to the top end of the slider. When the receiving plate 231 moves, the elastic element 2321 slides on the slide rail through the slider to prevent the elastic element 2321 from deforming when compressed, thereby enhancing the stability of the overall structure of the equipment.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
