Description

Technical Field

[0001] This invention relates to the field of heat sink spraying technology, and in particular to a heat sink spraying device. Background Technology

[0002] Heat sinks are an indispensable component in many electrical devices. To make heat sinks more aesthetically pleasing and have better corrosion resistance, different functional coatings are usually sprayed onto the surface of the heat sink. This spraying process is usually completed with the help of a heat sink processing spraying device.

[0003] When coating heat sinks, gases with pungent odors are generated. These gases generally need to be filtered before they can be released. However, existing filters can only be replaced when the spraying equipment is not in use, and cannot be replaced during the spraying process, which is quite inconvenient.

[0004] To address this, a heat sink processing and spraying device with patent number CN222035370U has been developed. While this device can solve the above problems to some extent, it still has the following drawbacks: when replacing the filter plate, it is necessary to pull the pull plate to move the sealing plate up so as to open the channel and insert the filter plate. However, during the process of opening the same side but before inserting the filter plate, the pungent gas in the exhaust gas discharge mechanism will inevitably flow out through the channel, thereby affecting the health of the workers. At the same time, the fixed nozzle is not convenient for spraying the outer wall of the heat sink. Summary of the Invention

[0005] The purpose of this invention is to provide a heat sink spraying device.

[0006] The technical problem of this invention is mainly solved by the following technical solution:

[0007] A heat sink spraying device includes a base and a housing disposed on top of the base. The top of the base is provided with a groove, and multiple sets of fixing mechanisms are arranged side by side at the bottom of the groove. A spraying mechanism extending into the groove is disposed inside the housing, and a filtering mechanism is also disposed on the top of the housing.

[0008] The spraying mechanism includes two sets of U-shaped seats that are inverted and arranged. A spray channel is provided in the side wall of the U-shaped seat. A nozzle communicating with the spray channel is provided on the inner side wall of the U-shaped seat. A positive and negative lead screw is provided in the housing, which passes through the U-shaped seat and is driven by a motor.

[0009] The filtration mechanism includes a square tube set on the top of the box, and rectangular tubes connected to the inside of the square tube are set on both sides of the square tube. Filter plates are set in the two sets of rectangular tubes, and a magnetic strip is set at one end of the filter plate.

[0010] Preferably, the U-shaped seat is connected to the liquid storage tank via a corrugated hose with a pump installed. The fixing mechanism is located inside the opening of the U-shaped seat. Two sets of U-shaped seats are located on both sides of the groove. The U-shaped seat is provided with screw holes for screwing with the positive and negative screws. The groove is provided with sliding grooves parallel to the positive and negative screws on the corresponding side walls. The U-shaped seat is provided with sliders located in the corresponding sliding grooves on the outer side wall.

[0011] Preferably, the fixing mechanism includes fixing blocks located on both sides of the bottom wall of the groove, wherein two sets of protrusions are provided between the two sets of fixing blocks, and a receiving groove with a T-shaped cross section is also provided in the side wall of the fixing block. A T-shaped connecting block extending to its outer side and connected to the back of the corresponding protrusion is provided in the receiving groove, and a rubber elastic block connected to the back of the connecting block is also provided in the receiving groove.

[0012] Preferably, the filter plate includes a plate body with both ends located inside the openings of corresponding rectangular tubes, wherein the plate body seals the internal openings of the rectangular tubes, and an installation cavity for accommodating activated carbon is provided in the side wall of the plate body. Ventilation holes communicating with the installation cavity are evenly provided on the upper and lower side walls of the plate body inside the openings of the rectangular tubes.

Detailed Implementation

[0020] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] A heat sink spraying device includes a base 1 and a housing 2 disposed on the top of the base 1. The top of the base 1 is provided with a groove 3. Multiple sets of fixing mechanisms 4 are arranged side by side at the bottom of the groove 3. The housing 2 is provided with a spraying mechanism 5 extending into the groove 3. The top of the housing 2 is also provided with a filtering mechanism 6.

[0022] The spraying mechanism 5 includes two sets of U-shaped seats 51 with inverted arrangement. A spray channel 52 is provided in the side wall of the U-shaped seat 51. A nozzle 53 communicating with the spray channel 52 is provided on the inner side wall of the U-shaped seat 51. A positive and negative lead screw 54 passing through the U-shaped seat 51 and driven by a motor 55 is provided in the housing 2.

[0023] The filter mechanism 6 includes a square tube 61 set at the top of the housing 2. A fan 10 is set at the bottom of the opening of the square tube 61. Rectangular tubes 62 connected to the inside are also set on both sides of the upper half of the square tube 61. Filter plates 63 are set in the two sets of rectangular tubes 62. A magnetic strip 64 is set at one end of the filter plate 63.

[0024] The U-shaped seat 51 is connected to the liquid storage tank via a corrugated hose 7 with a pump installed. The corrugated hose 7 is suspended by an elastic rope at the top of the tank 2, preventing it from sagging while allowing it to contract and expand. The fixing mechanism 4 is located within the opening of the U-shaped seat 51, with two sets of U-shaped seats 51 located on either side of the groove 3. The U-shaped seat 51 has screw holes for connection with the positive and negative lead screws 54. Figure 2As shown, a separator is provided between the forward and reverse threads in the forward and reverse screw 54 to prevent the screw hole in the left U-shaped seat 51 from moving to the reverse thread on the right, or to prevent the screw hole in the right U-shaped seat 51 from moving to the forward thread on the left. The groove 3 is provided with a sliding groove 8 parallel to the forward and reverse screw 54 on its two side walls. The outer wall of the U-shaped seat 51 is provided with a slider 9 located in the corresponding sliding groove 8. When the forward and reverse screw 54 rotates in the screw hole of the U-shaped seat 51 to drive its displacement, the U-shaped seat 51 will drive the slider 9 to slide in the sliding groove 8. The sliding groove 8 abuts against the slider 9 to indirectly prevent the U-shaped seat 51 and the forward and reverse screw 54 from rotating together.

[0025] The fixing mechanism 4 includes fixing blocks 41 located on both sides of the bottom wall of the groove 3, wherein two sets of protrusions 42 are provided between the two sets of fixing blocks 41, and a receiving groove 43 with a T-shaped cross section is also provided in the side wall of the fixing block 41. A T-shaped connecting block 44 extending to its outer side and connected to the back of the corresponding protrusion 42 is provided in the receiving groove 43, and a rubber elastic block 45 connected to the back of the connecting block 44 is also provided in the receiving groove 43.

[0026] The filter plate 63 includes a plate body 631 with both ends located inside the openings of corresponding rectangular tubes 62, wherein the plate body 631 seals the internal openings of the rectangular tubes 61. The side wall of the plate body 631 is provided with an installation cavity for accommodating activated carbon 632. The upper and lower side walls of the plate body 631 inside the openings of the rectangular tubes 61 are evenly provided with vent holes 633 communicating with the installation cavity. The magnetic strip 64 is located inside one set of rectangular tube openings and is fixedly connected to the corresponding end of the plate body 631. The other end of the plate body 631 is fixedly provided with a limiting part 634 located outside the corresponding rectangular tube 62. The limiting part 634 is fixed to the corresponding rectangular tube 62 by bolts.

[0027] The working principle of this invention is as follows: When in use, the heat sink is placed in the groove 3 and its bottom end is engaged between the two sets of protrusions 42. During installation, under the influence of the pressure from the bottom end of the heat sink, the protrusions 42 drive the connecting block 44 to slide in the receiving groove 43 while compressing the elastic block 45. When the heat sink is engaged between the two sets of protrusions 42, the elastic block 45 expands and pushes the protrusions 42 to move through the connecting block 44, thereby clamping a local area at the bottom of the heat sink. This achieves multi-point clamping and fixing of the bottom of the heat sink through multiple sets of fixing mechanisms 4, thus preventing the heat sink from shifting. At the same time, because the fixing block 41 and the protrusions 42 have small areas, even if they cover a small area of ​​the heat sink, it will not affect the normal spraying work. Furthermore, manual coating can be performed on the small area covered by the protrusions 42 later.

[0028] Once the fixing mechanism 4 has fixed the heat sink, the motor 55 drives the forward and reverse lead screws 54 to rotate in the screw holes of the U-shaped seat 51, thereby driving the two sets of U-shaped seats 51 to move, so as to reduce or increase the distance between the two sets of U-shaped seats 51. When the U-shaped seats 51 are moving, the pump injects the paint liquid in the storage tank into the spray channel 52 through the corrugated hose 7 and sprays it out from several moving nozzles 53, so that the paint mist can cover the entire outer surface of the heat sink. At the same time, the two sets of moving U-shaped seats 51 spray the heat sink, which can effectively improve the spraying efficiency and effect.

[0029] Meanwhile, the exhaust fan 10 draws the pungent odor from the housing 2 into the square tube 61, where it is filtered by activated carbon 632 in several filter plates 63. This allows the exhaust fan to filter out fine particles, organic matter, odors, and other pollutants from the air. It can also effectively remove harmful substances such as bacteria, viruses, mold, and odors from the air, thus ensuring that the exhaust gas generated during spraying is filtered before being discharged, guaranteeing the air quality of the working environment for the staff.

[0030] When filter plate 63 needs to be replaced, such as Figure 2 , 3 As shown, if the bottom filter plate 63 needs to be replaced, place the filter plate 63 to be replaced on the left side of the square tube 61, and insert the end with the magnetic strip 64 into the bottom left rectangular tube 62. At this time, the magnetic strips 64 in the two bottom filter plates 63 are magnetically connected in the rectangular tube 62, thus forming a whole between the two bottom filter plates 63, and separating the right limiting part 634 from the right rectangular tube 62. Then, push the bottom left filter plate 63 so that the left filter plate 63 can push the right filter plate 63 to slowly slide out of the left rectangular tube 62 and out of the opening of the square tube 61. The filter plate 63 slides through and into the rectangular tube 62 on the right, and finally slides out from the rectangular tube 62 on the right. During this process, the filter plate 63 on the left slides out from the rectangular tube 62 on the left, and then slides through the opening of the square tube 61 and into the rectangular tube 62 on the right. This is how the filter plate 63 is replaced. During the above process, the whole formed by the two sets of filter plates 63 on the left and right always seals the opening of the rectangular tube 62 and the opening of the square tube 61, so that no unfiltered gas will overflow through the square tube 61 and the rectangular tube 62. This not only makes it easy to replace the filter plate 63, but also ensures that there is no pungent odor that will affect the health of the staff.

[0031] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
