Description

[Technical Field]

[0001] This invention relates to the field of equipment coating, and more particularly to an air-compressed coating dot pen. [Background Technology]

[0002] Currently, the common method for preventing oxidation of the contact points between the flexible circuit and the motherboard in mobile phones is to apply contact oil. This process is completed manually using a roller-type fixture and an oiling pen.

[0003] However, the current coating process has the following problems:

[0004] 1) A large amount of grease accumulates inside the drum and cannot be fully utilized;

[0005] 2) Accumulated grease is easily contaminated when exposed to air for a long time. Once contaminated grease exceeds its service life, it can only be scrapped, causing serious harm to costs and the environment.

[0006] 3) The evenness of oil application cannot be effectively guaranteed when using a brush, and the reliability of the product cannot be effectively guaranteed;

[0007] 4) The brush has a limited oil content, requiring operators to constantly dip it in oil, which wastes time and increases labor intensity. Furthermore, long-term exposure to oil can affect the health of personnel, increasing medical costs for businesses and society.

[0008] Therefore, it is necessary to provide a new air-compressed coating contact pen to overcome the above-mentioned defects. [Summary of the Invention]

[0019] Figure 1 This is a schematic diagram of the structure of an embodiment of the air-compressed coating pen provided by the present invention.

[0020] Figure 2 This is a schematic diagram of the structure of the air-compressed coating contact pen provided by the present invention, in embodiment two.

Detailed Implementation Methods

[0021] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the invention and are not intended to limit the invention.

[0022] Please refer to Figure 1The present invention provides an air-compressed contact oil pen, including a cylinder 10, a roller assembly 20 connected to one end of the cylinder 10, and an air bladder 30 disposed on the cylinder 10; the cylinder 10 is provided with a receiving cavity 101 for receiving grease, and the roller assembly 20 includes a roller 21 partially received in the receiving cavity 101; the air bladder 30 is compressed so that the grease in the receiving cavity 101 comes into full contact with the roller 21, and the roller 21 rolls and drives the grease to be evenly applied to the motherboard of the electronic device.

[0023] The roller 21 is cylindrical and has grooves 211 on its side. These grooves 211 are used to evenly coat the grease in the first cavity 111 onto the surface of the roller 21, enhancing the roller 21's ability to retain the grease. In this embodiment, the grooves 211 are elongated, and there are multiple grooves 211 evenly spaced on the side of the roller 21, ensuring that the grease in the first cavity 111 is evenly distributed on the surface of the roller 21. In other embodiments, the grooves 211 may also be mesh-like.

[0024] Specifically, the cylinder 10 includes a first end 11 and a second end 12 connected to the first end 11. The first end 11 has a first cavity 111 that penetrates the first end 11 and is used to contain grease. The second end 12 has a second cavity 121 that communicates with the first cavity 111. The receiving cavity 101 is composed of the first cavity 111 and the second cavity 121. In this embodiment, the first end 11 and the second end 12 are threaded together. This facilitates the injection of grease into the first cavity 111, allowing the cylinder 10 to be reused. It also ensures a secure connection between the first end 11 and the second end 12. The second end 12 is used to cover the first cavity 111 of the first end 11, preventing the grease in the first cavity 111 from directly contacting the outside air and preventing the grease from being contaminated.

[0025] Furthermore, the first end 11 is frustum-shaped, and the first cavity 111 is cylindrical and coaxially arranged with the first end 11; the roller 21 is arranged on the top and bottom surfaces of the frustum of the first end 11, so that the roller 21 can roll on the motherboard of the electronic device and prevent the first end 11 from rubbing against the motherboard of the electronic device, thus affecting the performance of the motherboard of the electronic device.

[0026] The roller assembly 20 also includes a rotating shaft 22, which is disposed on the top and bottom surfaces of the frustum of the first end 11 and perpendicularly intersects the axis of the frustum of the first end 11. The roller 21 is cylindrical and has a central shaft hole. The rotating shaft 22 passes through the shaft hole of the roller 21 and is rotatably connected to the roller 21. The roller 21 is partially housed in the first cavity 111 and is in full contact with the grease in the first cavity 111. Part of the roller 21 is in contact with the motherboard of the electronic device and rolls on the motherboard, thereby uniformly coating the grease onto the motherboard of the electronic device.

[0027] In Embodiment 1, the airbag 30 is located at the end of the second end 12 away from the first end 11, and the airbag 30 is connected to the first cavity 111 through the second cavity 121. The grease in the first cavity 111 is squeezed by the airbag 30 and comes into full contact with the roller 21, so that the grease is evenly coated on the rotating roller 21.

[0028] Please refer to the above as well. Figure 2 In embodiment two, the airbag 30 is fixedly connected to the first end 11 and communicates with the first cavity 111. The airbag 30 is housed in the second cavity 121. A through hole 122 is provided on the side of the second end 12, and an elastic plate 123 housed in the second cavity 121 is fixedly connected to the edge of the through hole 122. The grease in the first cavity 111 squeezes the airbag 30 by squeezing the elastic plate 123, so that the grease is evenly coated on the rotating roller 21. The second cavity 12 serves to protect the airbag 30 on the one hand, and facilitates the squeezing of the airbag 30 on the other hand.

[0029] The air-compressed contact oil pen 100 also includes a protective sleeve 40, which is housed at one end of the first cavity 111 where the roller 21 is located, and is sandwiched between the roller 21 and the first cavity 111. On the one hand, it prevents the grease in the first cavity 111 from leaking when the roller 21 rolls, and on the other hand, it prevents the grease in the first cavity 111 from coming into contact with the outside air.

[0030] The air-compressed contact oil pen 100 provided by this invention contains grease in a first cavity 111, and under the compression of an airbag 30, it fully contacts a roller 21. The roller 21 rolls, causing the grease to be evenly applied to the motherboard of the electronic device. The air-compressed contact oil pen 100 provided by this invention has a simple structure, provides even application, has high utilization rate, and allows for long grease storage time.

[0031] The present invention is not limited to the description in the specification and embodiments, and other advantages and modifications can be readily realized by those skilled in the art. Therefore, the present invention is not limited to the specific details, representative devices and illustrated examples shown and described herein without departing from the spirit and scope of the general concept as defined by the claims and their equivalents.
