Description

Technical Field

[0001] This utility model relates to the field of electronic product manufacturing technology, and in particular to an antistatic device for vacuum handling of electronic products. Background Technology

[0002] With the continuous development of the semiconductor and electronics industries, vacuum handling tools have become an indispensable part of manufacturing. Vacuum handling is limited by the vacuum level of the chamber. Under high vacuum, the mean free path of particles is very large, and the probability of collision between particles is reduced. The static electricity generated during the handling process is difficult to annihilate through collisions between particles, and it will accumulate with the increase of handling times. When the static electricity accumulates to a certain level, it will cause defects such as electrostatic damage to the surface of the product or electrostatic adhesion, as well as unstable production efficiency. Traditional methods of eliminating static electricity are ion blowers or ion bars, but these methods cannot be used in vacuum chambers.

[0003] Chinese Patent No. CN212381448U discloses a vacuum static eliminator system for eliminating static electricity in a vacuum working chamber. The system includes a static eliminator device sealed to the vacuum working chamber, comprising a vacuum light source that directly irradiates the vacuum working chamber and generates ions therein; and an automatic shielding device sealed to the vacuum working chamber, comprising a light-shielding part and a driving mechanism. The light-shielding part is located on the light path, and the driving mechanism automatically controls the light-shielding part to open or close the light path.

[0004] The above-mentioned device has the following drawbacks: its working method involves irradiating ultraviolet light into the vacuum chamber, which cannot completely remove static electricity from the product, and it is inconvenient to irradiate the surrounding area at the same time, resulting in an unsatisfactory static electricity removal effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

An arc-shaped hole is formed on the inner side of the storage cylinder, and a sealing cap is fixedly connected to the outer wall of the storage cylinder on the side away from the vacuum chamber. A UV light emitting plate is fixedly connected to the inner side of the UV light ring frame.

[0009] The auxiliary mechanism includes a pull plate, which is slidably connected to the inner walls of both sides of the sealing cover. An arc-shaped plate is fixedly connected to the bottom outer wall of the pull plate, and a spring is fixedly connected to the outer wall of the pull plate on the side away from the arc-shaped plate.

[0010] The active roller penetrates the top outer wall of the frame and is rotatably connected to the side outer wall of the ultraviolet ring frame.

[0011] The ultraviolet light ring frame is rotatably connected to the outer wall of one side of the frame via bearings. There are several arc-shaped holes, which are respectively opened on the inner wall of the side of the storage tube.

[0012] Transparent glass is fixedly connected to the inner walls on both sides of the sealing cap.

[0013] The arc-shaped plate penetrates one side of the outer wall of the sealing cover, and the arc-shaped plate is engaged with one side of the inner wall of the limiting groove.

[0015] A sealing plate is hinged and snapped onto one side of the outer wall of the frame, and a vacuum pump is fixedly connected to one side of the outer wall of the sealing plate.

[0016] This utility model has the following beneficial effects:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 An antistatic device for vacuum handling of electronic products includes a vacuum chamber 1, a fixed frame 2 fixedly connected to one side of the outer wall of the vacuum chamber 1, and a frame 3 fixedly connected to the side of the fixed frame 2 away from the vacuum chamber 1. A static removal mechanism 6 is provided on the frame 3, and an auxiliary mechanism 7 is provided on the static removal mechanism 6. The static removal mechanism 6 includes an active roller 61, which is fixedly connected to the output end of the frame 3 through a coupling.

[0027] A UV ring frame 62 is rotatably connected to one side of the inner wall of the vacuum chamber 1 via a bearing. By setting the UV ring frame 62 and the UV emitting plate 63 to cooperate with each other, the surface around the electronic product is cleaned. Limiting grooves 64 are opened on both sides of the inner wall of the frame 3. A storage tube 65 is slidably connected to the inner wall of the limiting grooves 64. An arc-shaped hole 66 is opened on the inner side of the storage tube 65. A sealing cover 67 is fixedly connected to the outer wall of the storage tube 65 away from the vacuum chamber 1. The storage tube 65 facilitates the placement of electronic products. The UV emitting plate 63 is fixedly connected to the inner side of the UV ring frame 62.

[0028] Reference Figures 2-3 The active roller 61 passes through the top outer wall of the frame 3 and is rotatably connected to the side outer wall of the ultraviolet ring frame 62. The ultraviolet ring frame 62 is rotatably connected to the side outer wall of the frame 3 through bearings. There are several arc-shaped holes 66, which are respectively opened on the side inner wall of the storage tube 65. Transparent glass 68 is fixedly connected to the inner walls of both sides of the sealing cover 67. The transparent glass 68 facilitates personnel to observe the internal situation in real time.

[0029] A sealing plate 4 is hinged and snapped onto one side of the outer wall of the frame 3. A vacuum pump 5 is fixedly connected to one side of the outer wall of the sealing plate 4. The vacuum pump 5 is used to evacuate the inside of the storage cylinder 65 to a vacuum.

[0030] Reference Figures 3-4 The auxiliary mechanism 7 includes a pull plate 71, which is slidably connected to the inner walls of both sides of the sealing cover 67. An arc-shaped plate 72 is fixedly connected to the bottom outer wall of the pull plate 71. The pull plate 71 allows for convenient disassembly and assembly of the long-term storage tube 65.

[0031] A spring 73 is fixedly connected to the outer wall of the pull plate 71 away from the arc plate 72. The arc plate 72 penetrates the outer wall of the sealing cover 67 and is snapped into the inner wall of the limiting groove 64. The end of the spring 73 away from the pull plate 71 is fixedly connected to the inner wall of the sealing cover 67. The spring 73 generates a continuous pushing force on the pull plate 71. Frosted pads are fixedly connected to the outer walls of both sides of the pull plate 71.

[0032] Working principle: Electronic products are placed in the storage tube 65, then the sealing plate 4 is closed and the vacuum pump 5 is turned on to evacuate the inside to a vacuum. At the same time, the frame 3 is turned on to make the active roller 61 rotate. The rotation of the active roller 61 causes the ultraviolet light ring frame 62 to rotate. The rotation of the ultraviolet light ring frame 62 drives the ultraviolet light emitting plate 63 to rotate, so that the ultraviolet light emitting plate 63 irradiates through the arc-shaped hole 66 to clean the electronic products inside the storage tube 65 from multiple sides.

[0033] Meanwhile, during long-term use, by pulling the pull plate 71, the pull plate 71 moves and compresses the spring 73. At the same time, the movement of the pull plate 71 drives the arc plate 72 to move. The arc plate 72 moves and disengages from the limiting groove 64, and then the storage tube 65 can be pulled out for convenient cleaning and maintenance.
