Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic removal, and in particular to an adjustable electrostatic removal device based on charge neutralization and a use method thereof. Background Art

[0002] Static electricity is an issue that requires special attention during the use of electrical equipment. Static electricity refers to the electric field formed by uneven charge distribution. When electrical equipment rubs against other materials, moves relative to each other, or separates, especially in a dry environment, static electricity will be generated on the circuit due to friction. As static electricity accumulates, the amount of charge will gradually increase. When the amount of charge reaches a certain level, static electricity will be discharged instantly. This discharge phenomenon usually manifests as a short current pulse, and its energy is enough to damage the components on the circuit board.

[0003] In order to prevent static electricity from damaging circuit board components, in some cases, antistatic materials can be used to reduce the generation and accumulation of static electricity. These materials are usually conductive and can quickly disperse or conduct static charges to the ground. In a dry environment, static electricity can be reduced by increasing the humidity of the air. This can be achieved by using equipment such as humidifiers or sprayers. Both of these situations are not easy to operate and are not very convenient in most practical situations.

[0004] At present, static electricity removal devices are mainly used to remove static electricity from circuits. Grounding is usually used to remove static electricity, that is, the metal casing or other conductive parts of the electrical equipment are connected to the ground so that static electricity can be introduced into the ground in time. However, in some buildings, there are no wires that can be connected to the ground wire, so the grounding method has certain limitations. In addition, for some equipment, such as thinning machines and dicing machines, some of the internal circuits are not convenient to be connected to the ground wire, so the static electricity may cause damage to some circuits.

A guide cover 22 is inserted and rotated in the vertical direction inside the adjustment slot 2. The inlet of the guide cover 22 is located in the filter cover 21. An ionization air duct drive module 23 is installed in the guide cover 22.

Figure 4 As shown, the outlet of the air guide cover 22 is rotatably provided with a plurality of air guide plates 24 which are vertically arranged and spaced apart.

[0023] The fixed carrier plate 1 is specifically a rectangular plate structure, and a positioning groove 11 is provided at the bottom of the fixed carrier plate 1; a rotating rod 12 is rotatably installed inside the positioning groove 11; Figure 2 As shown, bevel gears are installed at both ends of the rotating rod 12, and a driving handle is installed at the middle position of the rotating rod 12; a bevel gear is installed at the bottom of the driving rod 13, and the bevel gear at the bottom of the driving rod 13 is meshed with the bevel gear at the side end of the rotating rod 12; the first movable plate 141 and the second movable plate 142 are both rectangular plate structures of the same size, and the inner sides are slidably installed on both sides of the fixed carrier plate 1, the outer side of the first movable plate 141 is rotatably connected to one end of the first support plate 151 through a rotating shaft, and the outer side of the second movable plate 142 is rotatably connected to one end of the second support plate 152 through a rotating shaft, and the first support plate 151 and the second support plate 152 are the same length; the inner wall of the fixed plate 16 is symmetrically fixed with a horizontally distributed first rotating shaft and a second rotating shaft along the center of the fixed plate 16, the other end of the first support plate 151 is rotatably connected to the first rotating shaft, and the other end of the second support plate 152 is rotatably connected to the second rotating shaft, wherein the outer side of the fixed plate 16 is made of rubber.

[0024] In this embodiment, when the static electricity of the circuit in the equipment is removed, the position of the fixed plate 16 is adjusted according to the position of the circuit, and the rotating rod 12 is rotated in the positioning groove 11 at the bottom of the fixed carrier 1. The bevel gears at both ends of the rotating rod 12 drive the driving rod 13 to rotate at both ends of the fixed carrier 1, and the driving rod 13 drives the first movable plate 141 and the second movable plate 142 to move up and down, so that the outer sides of the first movable plate 141 and the second movable plate 142 respectively drive the first support plate 151 and the second support plate 152 to move through the corresponding rotating shafts, and the other ends of the first support plate 151 and the second support plate 152 drive the fixed plate 16 to move outward and press against the inner wall of the equipment where the circuit to be eliminated is located, such as a thinning machine, a dicing machine and other equipment, to fix the position of the fixed carrier 1, so that it does not directly contact the circuit, and the problem of damage caused by contact with the circuit can be avoided.

[0025] like Figure 5 As shown, the air guide cover 22 includes an inlet section, a connecting section and an outlet section of an integrated structure. The inlet section and the outlet section are smoothly connected to the two ends of the connecting section respectively, so the opening of the outlet section is the outlet of the air guide cover 22, the inner wall of the connecting section is in contact with the ionization air duct driving module 23, the air inlet end of the ionization air duct driving module 23 faces the inlet of the filter cover 21, the inlet section is a multi-stage reduction structure, the opening gradually shrinks, and the end of the ionization air duct driving module 23 facing the inlet section is located in the filter cover 21. The outlet section specifically includes a first rectangular area, a trapezoidal area, and a second rectangular area. The length of the first rectangular area is greater than the length of the second rectangular area, the width of the first rectangular area is greater than the width of the second rectangular area, the inner end of the trapezoidal area is smoothly connected to the outer end of the first rectangular area, and the outer end of the trapezoidal area is smoothly connected to the inner end of the second rectangular area. Further, the opening of the second rectangular area is the outlet of the air guide cover 22.

[0026] The main structure of the guide plate 24 is a rectangular plate structure. A rotating shaft is extended at one end of the guide plate 24 in the height direction. The rotating shaft is rotatably inserted into the top of the second rectangular area. The upper end of the rectangular plate contacts the top of the second rectangular area, the lower end of the rectangular plate contacts the bottom of the second rectangular area, the inner end of the rectangular plate is located in the trapezoidal area, and the outer end of the rectangular plate extends out of the second rectangular area. After the rotating shaft extends out of the top of the second rectangular area, a cylindrical positioning block 25 is installed; the upper surface of the second rectangular area is installed with a positioning plate 26 through a spring and a bolt installed on the trapezoidal area. The positioning plate 26 is attached to one end of the positioning block 25 facing the trapezoidal area. The screw of the bolt extends from the inside to the outside of the top of the trapezoidal area and is inserted into one end of the spring. The other end of the spring presses against the inner wall of the positioning plate 26, so that the positioning plate 26 is fixed to the outside of the positioning block 25. When removing static electricity from the circuit in the device, the angle and blowing range of the guide cover 22 are adjusted according to the position of the circuit, the guide cover 22 is rotated inside the adjustment slot 2 so that its outer end is at a suitable tilt angle, the outer end of the guide cover 22 faces the circuit direction, and the angles of multiple guide plates 24 are rotated at the outer end of the guide cover 22. The guide plate 24 drives the positioning block 25 to be at a suitable tilt angle through the rotating shaft at the top of the guide plate 24, and drives the positioning plate 26 to apply pressure to the outer side of the positioning block 25 under the elastic force of the spring, fixes the position of the positioning block 25, and thus fixes the position of the positioning block 25. The guide plate 24 is fixed in position, and the ionization air duct drive module 23 on the inner side of the guide cover 22 is working. Then, the airflow is filtered by the filter cover 21 and then sucked into the inside of the guide cover 22. The filter cover 21 reduces the problem of dust being sucked in. The guide cover 22 sprays out a high-speed airflow. When this high-speed airflow blows toward the surface of the circuit with static electricity, the ions will react with the static charge on the surface to neutralize the static electricity, thereby removing the static electricity. The guide plate 24 guides the direction of the airflow, covers a wide range, and efficiently removes static electricity, while reducing the adhesion of dust on the circuit.

Two fixed covers 34 are movably overlapped on each guide block 32, the opening of the fixed cover 34 faces downward and is in close contact with the upper surface of the fixed bracket 3, and a connecting plate 35 is connected between the two fixed covers 34.

[0028] Furthermore, if Figure 7As shown, the guide block 32 of the present invention includes a guide head, a guide rod and a guide seat of an integrated structure. The guide head is cylindrical and has an outer diameter greater than the width of the guide groove 31. The guide rod is cylindrical and has a gap with the inner wall of the guide groove 31. The guide rod is distributed in the guide groove 31. A tension spring in a compressed state is installed between the upper surface of the guide head and the top of the fixed cover 34. The lower surface of the fixed bracket 3 overlaps the junction of the guide rod and the guide seat.

[0029] When removing static electricity from the circuit in the device, after the fixed carrier board 1 is fixed to one side of the circuit, the fixed bracket 3 is above the circuit, and the connecting plate 35 is pulled to drive the fixed cover 34 to move slightly upward through the tension spring to lose the fixation of the guide block 32, and the guide block 32 is pushed to move along the guide groove 31, and the bottom of the two guide blocks 32 drives the static electricity detection module 33 to move to a suitable position to detect static electricity on the circuit, and the tension of the tension spring can drive the fixed cover 34 to move downward, and the bottom of the fixed cover 34 contacts the top of the fixed bracket 3, and the friction between the fixed cover 34 and the upper surface of the fixed bracket 3, and the friction between the lower surface of the fixed bracket 3 and the upper surface of the guide seat is large, which can play a role in fixing the position, and under the action of the tension spring, the bottom edge position of the fixed cover 34 is installed at a suitable position on the top of the fixed bracket 3, increasing the friction with the top of the fixed bracket 3, and preventing the guide block 32 from moving at will. The position of the guide block 32 is fixed by the tension spring, and the static electricity detection module 33 continuously detects static electricity to realize circuit detection.
