DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0018] Referring to the drawings Figures 1-5 An anti-static vacuum release box for chip includes a bottom box 1 and an upper cover 2 connected by a hinge, the bottom box 1 is provided with a tray, the bottom box 1 is provided with a sealing groove 15 and an anti-static chamber 16, the upper cover 2 is fixed with a sealing anti-static device 3 matched with the sealing groove 15.

[0019] The sealing anti-static device 3 comprises a rubber sealing frame 31, a plurality of O-shaped air cavities 33 are arranged in each side of the rubber sealing frame 31 in an equidistant manner, the O-shaped air cavities 33 are filled with air, one side of the O-shaped air cavities 33 is a shaped arc-shaped protrusion 34 which is integrally formed with the rubber sealing frame 31, air cylinders 35 are arranged on both sides of the O-shaped air cavities 33 in the rubber sealing frame 31, the air cylinders 35 and the O-shaped air cavities 33 are communicated through air passages 36, an operation groove 39 is arranged on the upper side of the rubber sealing frame 31, and a plurality of piston rods 37 are slidably arranged in the air cylinders 35, and an anti-static coating plate 38 is fixed between the piston rods 37 and arranged in the operation groove 39.

[0020] When the bottom box 1 and the upper cover 2 are folded, the rubber sealing frame 31 enters the sealing groove 15, the shaped arc-shaped protrusion 34 is pressed by the sealing groove 15 when the rubber sealing frame 31 enters, so that the O-shaped air cavities 33 are pressed to discharge air, at this time, the O-shaped air cavities 33 are deformed, the air is introduced into the air cylinders 35 through the air passages 36, so that the piston rods 37 are lifted by the air to move to the operation groove 39, so that the anti-static coating plate 38 is pushed into the anti-static chamber 16, and the tray at the bottom of the bottom box 1 is surrounded, so that the chips placed on the tray can be well prevented from static electricity;

[0021] Because the O-shaped air cavities 33 and the shaped arc-shaped protrusion 34 are shaped during processing, when the upper cover 2 is taken out of the bottom box 1, the pressing force on the shaped arc-shaped protrusion 34 disappears, so that the rubber material on the side of the shaped arc-shaped protrusion 34 and the O-shaped air cavities 33 can rebound through the elastic restoring force, so that the shaped arc-shaped protrusion 34 and the O-shaped air cavities 33 restore to the original shape, and the air in the air cylinders 35 is absorbed in the recovery process, so that the piston rods 37 are sucked back to the original position, so that the anti-static coating plate 38 is pulled to enter the operation groove 39 again;

[0022] Therefore, through the mode that the anti-static coating plate 38 is taken out of the operation groove 39 when the bottom box 1 and the upper cover 2 are folded, and the anti-static coating plate 38 enters the operation groove 39 when the bottom box 1 and the upper cover 2 are separated, the anti-static effect can be achieved, and the release box can be protected when it is not in operation, so that damage to the device when the release box is placed or taken is avoided, and the anti-static ability is not reduced after long-term use;

[0023] It should be noted that the anti-static coating plate 38 is made of metal-coated plastic, which is a common anti-static material in the technical field, and therefore is not described in detail.

[0024] Specifically, as shown in FIG. 1, the bottom box 1 comprises a bottom box body 11 and a tray 12 arranged on the bottom box body 11, the tray 12 is used to place the chips, and the tray 12 is provided with a plurality of anti-static holes 121. Figure 1As shown, the bottom box 1 includes a fixedly connected side wall 11 and a base 12, a plurality of supporting legs 14 are fixedly installed on the periphery of the base 12, a blocking frame 13 is fixedly installed on the supporting legs 14, a sealing groove 15 is formed between the side wall 11 and the blocking frame 13, and the lower portion of the blocking frame 13 and the sealing groove 15 are communicated to form an anti-static chamber 16; and a tray is installed on the base 12 and located in the middle of the blocking frame 13.

[0025] In this way, the bottom box part of the release box is formed, and through the arrangement, the anti-static chamber 16 is formed, which can directly surround the tray after the anti-static coating plate 38 enters.

[0026] In the embodiment, the O-shaped air cavity 33 is provided with a spring sheet 300, the spring sheet 300 is in an O-shaped structure, and when the O-shaped air cavity 33 is extruded and deformed, the spring sheet 300 is also deformed, and when the extrusion force disappears, the spring sheet 300 rebounds, thereby improving the restoring force of the O-shaped air cavity 33 and ensuring that the O-shaped air cavity 33 can restore to a circular shape after extrusion, and the arrangement of the spring sheet 300 will not block the air cavity 36.

[0027] It should be further explained that the rubber sealing frame 31 is provided with a first reinforcing wall 100 and a second reinforcing wall 200, the air cavity 36 is located in the second reinforcing wall 200, the air cylinder 35 is located in the first reinforcing wall 100, and the rubber sealing frame 31 is further provided with a reinforcing rib 32.

[0028] Specifically, the first reinforcing wall 100 and the second reinforcing wall 200 can ensure that the air cavity 36 and the air cylinder 35 are not deformed when the rubber sealing frame 31 is extruded and deformed, and the reinforcing rib 32 ensures that the rubber sealing frame 31 will not be excessively deformed.
