Description

Technical Field

[0001] This utility model relates to the field of thermal grease coating equipment, and particularly to thermal grease coating testing equipment. Background Technology

[0002] When assembling chassis products using automated assembly, heat sinks need to be installed during the assembly process. The most important step is to apply thermal grease to the heat sink. If the thermal grease is not applied properly, it will result in poor heat dissipation during the use of the chassis product. The current method of coating is machine coating. When unqualified thermal grease coatings are detected by manual inspection, the heat sink needs to be placed on the machine for recoating. This results in low assembly efficiency. However, on automated assembly lines, this processing method cannot meet the assembly speed of the production line. Utility Model Content

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] See Figures 1-2 This utility model provides a technical solution:

[0021] A thermal grease coating and testing device includes a coating stage 30, a testing camera 31, a light frame 32, a lamp tube 33, a light shield 34, a light shield plate 35, a light shielding drive 36, a coating assembly, and a part transport assembly. The light shield 34 is sealed and fixedly mounted on the coating stage 30. The coating assembly is fixedly mounted on the coating stage 30 and located inside the light shield 34. The part transport assembly is fixedly mounted on the coating stage 30, with one end engaging with the coating assembly. The other end of the part transport assembly is located outside the light shield 34. A transport channel that engages with the part transport assembly is provided on the side wall of the light shield 34. The light shield plate 35 is slidably mounted on the transport channel and engages with the transport channel. The light shield plate 35 is fixedly connected to the output end of the light shielding drive 36. The fixing part of the light shielding drive 36 is fixedly mounted on the light shield 34. The light frame 32 is fixedly mounted inside the light shield 34 and is located between the transport channel and the coating assembly. The testing camera 31 and the lamp tube 33 are both fixedly mounted on the light frame 32. In the automated assembly line, the detection camera 31, lamp tube 33, light shielding drive component 36, coating component and part transport component are all electrically connected to the control center in the prior art. The function of the light shield 34 and the light shield plate 35 is to block the outside light from entering the light shield 34, so as to prevent the detection camera 31 from observing the thermal grease coating on the heat sink with a large error. The inspection camera 31 is a conventional camera that can observe the thermal grease coating on the heat sink. After the thermal grease coating on the heat sink is processed, the inspection camera 31 performs an inspection. If the inspection fails, the inspection camera 31 transmits a signal to the part transport assembly. The part transport assembly carries the heat sink to the coating assembly for secondary coating processing. The coating assembly is used to apply the thermal grease coating to the heat sink. The light-shielding drive 36 is a conventional electric push rod that drives the light-shielding plate 35 to move up and down. When the part transport assembly enters the light-shielding cover 34, the light-shielding plate 35 moves down to block the transport channel, thus reducing the amount of external light entering the light-shielding cover 34 and causing adverse effects. When the inspection camera 31 detects that the coating is qualified, the light-shielding drive 36 drives the light-shielding plate 35 up to open the transport channel, allowing the part transport assembly to work smoothly. The light holder 32 is used to install the inspection camera 31 and the lamp tube 33. The lamp tube 33 emits light to illuminate the thermal grease coating on the heat sink, which facilitates the inspection camera 31's judgment.

[0022] In some embodiments, the part transport assembly includes a coating guide rail 37, a coating slide 38, a coating motor 39, and a coating part holder 40. The coating guide rail 37 is fixedly mounted on the coating stage 30, with one end engaging with the coating assembly. The other end of the coating guide rail 37 is located on the outside of the light shield 34. The coating slide 38 is slidably mounted on the coating guide rail 37. The coating motor 39 is fixedly mounted on the coating stage 30 and is used to push the coating slide 38 to slide. The coating part holder 40 is fixedly mounted on the coating slide 38. A coating lead screw is fixedly mounted on the output portion of the coating motor 39, and the coating lead screw is threadedly engaged with the coating slide 38. The coating motor 39 is a conventional motor connected to the control center. The coating motor 39 is fixed on the coating table 30 to drive the coating sliding seat 38 to slide on the coating guide rail 37. The coating part seat 40 is used to place the heat sink. The heat sink is placed on the coating part seat 40 on the outside of the light shield 34. Then, the coating motor 39 sends the heat sink directly under the coating mesh 49 for thermal grease coating. After the thermal grease coating is qualified, it is sent to the outside of the light shield 34 and then the next product is replaced for further processing.

[0023] In some embodiments, the coating assembly includes a coating vertical plate 41, a coating horizontal plate 42, a coating brush 43, a horizontal plate drive 44, and a brush drive 45.

The coating brush 43 is fixedly mounted on the output part of the brush cylinder 46, the brush cylinder 46 is fixedly mounted on the brush sliding seat 47, and the brush sliding seat 47 is mounted on the output part of the brush drive 45. The coating vertical plate 41 is vertically fixed on the coating table 30. A guide rail is provided on the coating vertical plate 41. The coating horizontal plate 42 slides vertically on the guide rail provided on the coating vertical plate 41. Both the horizontal plate drive unit 44 and the brush drive unit 45 are existing motors electrically connected to the control center. A horizontal plate lead screw is provided on the output end of the horizontal plate drive unit 44, and the lead screw is threaded into the coating horizontal plate 42. A guide rail is provided on the coating horizontal plate 42. The brush sliding seat 47 slides horizontally on the guide rail on the coating horizontal plate 42. The brush sliding seat 47 is mounted on a transmission belt, and two rollers are mounted on both sides of the transmission belt. Two rollers are rotatably mounted on the coating plate 42. The brush drive unit 45 is fixedly mounted on the coating plate 42 and its output end is connected to one of the rollers. Under the action of the brush drive unit 45, the brush slide seat 47 moves horizontally. The brush slide seat 47 drives the coating brush 43 to apply thermal grease through the brush cylinder 46. The brush cylinder 46 is a cylinder in the prior art. The brush cylinder 46 is connected to the air source through a solenoid valve. The solenoid valve is electrically connected to the control center. The brush cylinder 46 can drive the coating brush 43 to move up and down.

[0026] In some embodiments, an operating door 51 is provided on the side wall of the light shield 34, and the operating door 51 is arranged adjacent to the conveying channel. During the assembly of the chassis product, the chassis product comes in various sizes, and therefore the heat sinks used also come in various sizes. Therefore, the specifications of the coating mesh 49 on the coating rack 48 are adapted to different sized heat sinks. The operating door 51 is provided for replacing the coating mesh 49. During processing, the operating door 51 on the light shield 34 is in a closed state; it is opened when replacing the coating mesh 49 and closed after replacement.
