Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a spraying device for producing heat sinks. Background Art

[0002] Heat sinks are indispensable components in many electrical equipment. In order to make the heat sink more beautiful and have better corrosion resistance, it is usually necessary to spray the surface of the heat sink evenly. The spraying process is usually completed with the help of a spraying device for heat sink production.

[0003] However, the existing spraying devices are unable to spray and bake the heat sink paint in all directions. If the heat sink is sprayed unevenly, the heat sink heat dissipation effect will be poor and the life of the heat sink will be affected. Uneven baking of the heat sink paint will also lead to poor heat dissipation effect and short life. It will also make the heat sink coating uneven, resulting in poor appearance. In order to allow the heat sink paint surface to be completely coated with paint and dried evenly, we propose a spraying device for heat sink production. Utility Model Content

[0004] The utility model aims to provide a spraying device for producing heat sinks to solve the above-mentioned problems.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A spraying device for heat sink production comprises a base, wherein support ring 1, support ring 2 and support ring 3 are arranged above the base, a rotating wheel is slidably arranged inside the support ring 1, a spraying plate is arranged between the support ring 1 and the support ring 2, a heat insulation cover is arranged between the support ring 2 and the support ring 3, and a plurality of heating lamps are arranged in a circular array inside the heat insulation cover.

[0007] As a further solution of the utility model: a motor is arranged below the rotating wheel, a belt is arranged outside the rotating wheel, and an output end of the motor is connected to the belt.

[0008] As a further solution of the utility model: a spraying plate is symmetrically connected to one side of the rotating wheel, and the spraying plate is rotatably connected to the second supporting ring.

[0009] As a further solution of the utility model: a plurality of support columns are arranged on the top of the base, and an annular track is arranged above the support columns.

[0010] As a further solution of the utility model: a plurality of sliding blocks are slidably arranged on the outer side of the annular track.

[0011] As a further solution of the utility model: the annular track passes through the inside of the support ring one, the support ring two and the support ring three.

[0012] As a further solution of the utility model: a tooth groove is provided below the annular track.

[0013] As a further solution of the utility model: a driving motor is arranged inside the sliding block, an output end of the driving motor is connected to a gear, and the gear is meshed with the tooth groove.

[0014] Beneficial effects of the utility model:

[0015] (1) The arc-shaped spray plate can adapt to heat sinks of different shapes. When the motor drives the rotating wheel through the belt, the spray plate rotates in a circular trajectory to spray the heat sink repeatedly, so that the paint can be evenly sprayed on the surface of the heat sink, achieving all-round spraying. The heat insulation cover is used to prevent the heat loss of the heating lamp tube, so that the heat of the heating lamp tube can be concentrated on the heat sink to dry the paint surface. At the same time, the heat insulation cover can prevent the influence of external floating objects or mosquitoes on the baking paint surface, thereby improving the quality and reliability of the heat sink paint baking;

[0016] (2) Push the clamping plate to one side, and then place the heat sink between the two clamping plates. The thrust generated by the compression of the spring is transmitted to the clamping plate, so that the heat sink is clamped between the two clamping plates. The heat sink is placed between the clamping plates above and on both sides of the sliding block, respectively. By starting the drive motor, the drive motor drives the gear to rotate. The drive motor is connected to the gear and the tooth groove through meshing, so that the sliding block slides along the circular track. By fixing the heat sink on the outside of the sliding block, the heat sink is prevented from shifting and falling during the spraying process, and at the same time, the stability and accuracy of the heat sink during the spraying process are ensured.
