Description

Technical Field

[0001] The utility model relates to the field of silicone grease application, in particular to a silicone grease application assembly for aluminum substrates. Background Art

[0002] In the manufacturing process of motorcycle controllers, aluminum substrates are widely used as the installation basis for electronic components due to their good thermal conductivity and mechanical strength. The heat conduction efficiency between the aluminum substrate and the radiator is directly related to the heat dissipation performance and long-term stability of the controller. As a thermal interface material, silicone grease can effectively fill the microscopic air gaps between the aluminum substrate and the radiator, improving the heat conduction efficiency. Silicone grease needs to be applied on the aluminum substrate. In the prior art, it is generally applied manually. When applying manually, there are the following problems: it is difficult to achieve the consistency of the area and thickness of the silicone grease on the aluminum substrate by manual application, resulting in uneven heat dissipation effects and affecting the overall performance and reliability of the controller. During the manual operation process, the excessive use and uneven distribution of silicone grease lead to material waste and increase the production cost. In addition, the manual operation efficiency is low, which is not conducive to the rapid application of silicone grease on the aluminum substrate. Summary of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a silicone grease application assembly for aluminum substrates. The application assembly has a simple structure, can quickly apply silicone grease on the aluminum substrate, has a high application efficiency, and the applied area and thickness are uniform, avoiding the waste of silicone grease.

[0004] To achieve the above object, the utility model adopts the following technical scheme: A silicone grease application assembly for aluminum substrates, comprising:

[0022] The technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] As Figures 1-3 shown, a silicone grease coating assembly for an aluminum substrate includes:

[0024] A horizontal moving assembly, on which a moving block 1 is installed;

[0025] A silicone grease coating assembly, including a moving plate 2 fixed on the horizontal moving assembly. A silicone grease pushing and scraping unit and a silicone grease coating unit are fixed on the moving plate 2. The silicone grease pushing and scraping unit includes a scraping mechanism and a material returning mechanism. A flexible scraping plate 3 is fixed on the scraping mechanism, and a flexible material returning plate 4 is fixed on the material returning mechanism. The silicone grease coating unit includes a plurality of lifting mechanisms, and a coating block 5 is fixed on the lifting rod of the lifting mechanism;

[0026] A material storage assembly, including a material storage bin 6. The material storage bin 6 includes a bottom plate 7. Side plates 8 are fixed on the front and rear sides of the bottom plate 7, and a baffle 9 is fixed on the left side of the bottom plate 7. The bottom plate 7 includes a material storage area 10 and a coating area 11. The material storage area 10 and the coating area 11 are connected by an inclined surface, and a plurality of deposition tanks 12 are also opened in the coating area 11.

[0027] The process of using this utility model is as follows. Install the coating assembly on the coating area 11 of the aluminum substrate. When it is necessary to coat the aluminum substrate, first load a certain amount of silicone grease liquid in the material storage area 10 of the material storage bin 6, and also load silicone grease liquid in the deposition tank 12. Then place and position the aluminum substrate, start the coating assembly, and the lifting rod of the lifting mechanism begins to descend. The coating block 5 comes into contact with the silicone grease liquid in the deposition tank 12, and the silicone grease liquid with the same area as the deposition tank 12 will adhere to the bottom of the coating block 5. Subsequently, the moving block 1 of the horizontal movement assembly moves to the right, driving the moving plate 2 to move to the right. During the process of the moving plate 2 moving to the right, the scraping mechanism scrapes the silicone grease liquid to the right and reaches the coating area 11. Since the coating area 11 has a deposition tank 12, at this time, the silicone grease liquid will enter the deposition tank 12 to supplement the silicone grease liquid. At this time, because the amount of silicone grease liquid is large, after supplementing the deposition tank 12, it will also overflow from the deposition tank 12. The horizontal movement assembly starts to reset. At this time, the material return mechanism will scrape the overflowed silicone grease liquid back into the material storage bin 6 again. In this way, one coating of the aluminum substrate is completed. Repeating the above actions can continuously coat the aluminum substrate.

[0028] Further, the horizontal movement assembly is a ball screw mechanism. The moving block 1 is connected to the screw rod 13 of the ball screw mechanism, and the moving plate 2 is fixed on the moving block 1. Specifically, the horizontal movement assembly of this utility model adopts a ball screw mechanism, which has stable transmission and high precision, ensuring accurate coating of the aluminum substrate.

[0029] Further, the scraping mechanism includes a guiding block fixed on the moving plate 2. Two guiding rods 14 are slidably connected in the guiding block, and the flexible scraping plate 3 is fixed at the bottom of the guiding rods 14. Specifically, in this utility model, the scraping mechanism is a guiding block directly fixed on the moving plate 2. Under the action of gravity, the guiding rods 14 in the guiding block will drive the flexible scraping plate 3 to directly contact the material storage bin 6, thereby realizing the scraping of the silicone grease liquid.

[0030] Further, the material return mechanism is a material return cylinder 15, and the flexible material return plate 4 is fixed on the cylinder rod of the material return cylinder 15. Specifically, if only the scraping mechanism is set, it will cause the coating area 11 to be not scraped clean during material return. Therefore, a material return cylinder 15 is set, and the flexible material return plate 4 is fixed on the cylinder rod of the material return cylinder 15, so that when the horizontal movement assembly moves to the left, it can normally scrape the silicone grease liquid.

[0031] Furthermore, both the flexible scraping plate 3 and the flexible material returning plate 4 include a clamping plate 16 having a clamping groove, and a rubber plate is fixed in the clamping groove. Specifically, the flexible scraping plate 3 and the flexible material returning plate 4 of the present utility model are both fixed in the clamping plate 16. The flexible scraping plate 3 and the flexible material returning plate 4 both adopt rubber plates. Through the arrangement of the rubber plates, they will not interfere with the inclined surface.

[0032] Furthermore, the lifting mechanism is a lifting cylinder 17, and the number of the lifting cylinders 17 is three. Guide rods 14 are slidably connected in both the material returning cylinder 15 and the lifting cylinder 17. Specifically, in order to prevent the lifting cylinder 17 and the material returning cylinder 15 from deflecting when descending, guide rods 14 are slidably connected in both the material returning cylinder 15 and the lifting cylinder 17. The clamping plate 16 on the material returning cylinder 15 is also fixedly connected to the guide rod 14, and the coating block 5 on the lifting cylinder 17 is also fixedly connected to the guide rod 14.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered by the scope of the claims of the present utility model.
