[Industrial application field]

This invention removes static electricity from parts and materials used in the manufacture of liquid crystal display devices. This invention relates to a static eliminator.

0002

[Conventional technology]

Various parts and materials such as electronic parts are manufactured during the manufacturing process to prevent functional failure due to static electricity. As a means to eliminate static electricity, the static electricity eliminator shown in Figure 8 is used. A static eliminator (hereinafter referred to as a static eliminator) AP is used. This static eliminator AP is a neutralizing ion Figure 8 shows the air containing neutralized ions (hereinafter referred to as ionized air). As shown in FIG. It is configured to project diagonally from above and neutralize charged ions.

0003 Projection of this ionized air requires a large air volume, but due to space constraints, it becomes large. In order to eliminate static electricity using relatively small equipment, it is necessary to A method of partially projecting the ionized air while fixing the projection direction was carried out. ing. This method is used to increase the amount of air projected per unit area, as shown in Figure 9. Therefore, the exhaust port of the static eliminator AP is divided into upper and lower parts by a plurality of air blow direction control members 14. , a plurality of ventilation holes 16 having a flat cross section are formed, and ion vacancies from each ventilation hole 16 are The energy is divided into small lots of divided airflow collections (hereinafter tentatively referred to as divided airflow) D1~ It forms Dn. Note that the reference numeral 12 shown in FIG. 9 is a fan, and the reference numeral 13 is an iodine. Indicates the means of generation.

[Problem that the idea aims to solve]

In this way, in the conventional static eliminator AP, the air blowing direction is fixed and the divided air flux D1~ The structure is such that a large amount of ionized air is irradiated for each Dn, so static electricity is removed. When the part BP to be used is a small item that falls within one divided air flux of ionized air, fully demonstrates its performance.

[0005] However, electronic components, especially liquid crystal display elements and plasma display devices, for which demand is increasing recently, The display area of flat displays such as LCD monitors has greatly expanded, and, for example, LCD In the case of display element units, the size is smaller than the conventional size of 20 to 30 mm x 50 to 80 mm. Currently, the size has increased to 120 to 150 mm x 200 to 300 mm. For this reason In order to eliminate the static electricity, ionized air is uniformly and simultaneously projected over the entire surface of the static electricity-eliminating component BP, etc. I can't do it.

[0006] When projecting ionized air locally at intervals on the surface of a large-area component, this Ionized air is secondarily applied by diffusing out of the directly projected split air flux. Static electricity outside the divided air flux is removed, but the removal speed is slow and it takes a long time to remove the static electricity. It takes time. According to actual measurements, ionized air is projected at an air flow rate of 40 to 50 liters/minute. It took 1 to 2 minutes to remove the static electricity.

[0007] Therefore, the static eliminator AP is incorporated into the manufacturing process of parts and materials that require static neutralization. There is a problem that if there is too much work, the work loss will be large. To the total area of static electricity removal component BP In order to simultaneously project ionized air across the ground, the static eliminator needs to be larger. However, if the size is increased, the cost will increase.

[0008] This invention solves these problems and eliminates static electricity in a short time without the need for enlargement. The purpose of the present invention is to provide a static eliminator that can eliminate static electricity.

[0009]

[Means to solve the problem]

In order to achieve the above purpose, the present invention includes a fan, ion generating means for ionizing air from the fan; A swingable air blowing direction control unit provided downstream of the ion generating means in the air blowing direction. wood and A static eliminator comprising a driving means for swinging an air blowing direction control member. It is.

0010

[Effect]

According to the present invention, the ionized air is controlled by a blowing direction control member that is divided into multiple parts in the vertical direction. After that, the air is partially projected onto the material to be neutralized, but the air blowing direction control member is swung vertically. Therefore, the amount of ionized air onto the ionized air projection surface caused by the divided air blowing direction control member is Since there are no blind spots, static electricity can be removed from the parts to be neutralized in an extremely short time. .

【Example】

FIG. 1 is a cross-sectional view of a static eliminator A according to an embodiment of the present invention taken along the direction of air blowing. FIG. 2 is a front view of a portion thereof. As shown in Figures 1 and 2, static electricity A static eliminator A for removing static electricity is built into a housing 1 that is open on one side. The axial fan (hereinafter referred to as fan) 2, the ion generating means 3, and the fan 2 a blowing direction control member 4 for energized air; and a driving means for swinging the blowing direction control member 4. 5.

0012 As shown in FIG. outside air is sucked in, and ions are generated in the housing 1 by the ion generating means 3. , the air that has been ionized by contact with the ions is provided on the other side of the housing 1. The discharged air is discharged from the ventilation hole 6, and discharges static electricity from each of the objects to be removed, such as polarizing plates constituting a liquid crystal display device. Project onto parts. This neutralizes and eliminates the static electricity that accumulates on each of these parts to be neutralized. leave

[0013] As shown in the perspective view of FIG. A high-frequency current from a high-voltage power source 10 is applied to the high-voltage electrode 8 connected to the pole 9 through the terminal 8a. By applying a The air sent to is ionized into positive (+) and negative (-). In addition, Takashu The wave current has a voltage of 10,000 to 50,000 volts, and the grid spacing d of the metal electrode 9 is 5 to 10 mm. is set to

[0014] As shown in the plan view of FIG. 4, this ionized air It is discharged from the ventilation hole 6 through the material 4, and becomes a horizontally long band-shaped divided air flux. Projected toward the parts B to be neutralized, the positive (+) and magnetic lights that are charged on these parts B are The negative (-) electrostatic ion E1 is neutralized by the electrostatic force with the projected ion E2, and the electrostatic Static electricity is removed.

[0015] Referring again to FIG. 1, a plurality of ventilation direction control members 4 are installed in the ventilation hole 6, They are arranged with their planes facing each other at a predetermined interval in the vertical direction, and are supported by a support shaft 11. It is pivotally attached to the front wall 1a of the housing 1. In this invention, each blow direction control section The member 4 is made to be able to swing up and down simultaneously by a driving means 5.

[0016] The driving means 5 is connected to a rear end portion (directed toward the inside of the housing 1) of each of the air blowing direction control members 4. A drive rod 14 is rotatably supported via a pin 12 on one end A connecting rod 15 is supported by a pin at the lower end of the rod 14, and the other end of the connecting rod 15 is pivotally fixed. A crank mechanism 16, a motor 17 for rotating the crank mechanism 16, and a motor for rotating the crank mechanism 16. It has a pulley 18, a crank pulley 19, and a belt 20. Each air blow direction system The control member 4, the front wall 1a of the housing 1, and the drive rod 14 are connected in a parallelogram shape. Therefore, when the drive means 5 is actuated, each direction control member 4 moves upward while maintaining parallelism. rock down.

[0017] FIG. 5 shows a component to be neutralized, for example, a polarizing plate B1, using the static eliminating device A of the present invention. This shows how it is used to eliminate static electricity. Polarizing plate B1 is placed on a horizontal workbench C. The polarizing plate B1 is placed at an angle so that the polarizing plate B1 can be irradiated over as wide a range as possible. Projects ionized air from above. According to the example, the projected air volume is 50 to 60 liters. 1/min, and the projection angle of the ionized air shown in FIG. 5 is the angle α1= 20°, and the angle α2=50°, using the driving means 5 of the present invention shown in FIG. When the direction control member 4 is swung up and down 5 to 10 times per minute, the angle α3 becomes approximately 10° and angle α4 is approximately 60°, the time required to remove static electricity is about 3 to 10 seconds. Therefore, suitable static elimination is performed.

[0018] Divided air flux of ionized air projected from the ventilation hole 6 (shown as D1 to Dn in FIG. 9) are diffused and become continuous with each other or intersect with each other as they move away from the outlet of the vent hole 6. A collective airflow D (see Figure 9) is formed, but if the distance from the ventilation hole 6 is long, the air volume and wind pressure will decrease. Both are weak and the static elimination action is extremely slow, and it takes a long time to eliminate static electricity, so it is not suitable for practical use. stomach.

[0019] For this reason, in the present invention, the above-mentioned device is placed near the outlet of the ventilation hole 6 and in a position where both the air volume and the wind pressure are strong. By arranging the parts B to be neutralized and simultaneously swinging each blowing direction control member 4, , blind spots between the divided air fluxes D1 to Dn are eliminated. Therefore, the exemption Although there is a slight time lag over the entire surface of the polarizing plate B1, which is an electrical component, Ion air is projected almost simultaneously, and static electricity is eliminated in a short time.

[0020] FIG. 6 shows the static elimination effect range for the entire projection range β1 of ionized air by the driving means 5. It is a side view showing β2. As shown in Figure 6, the ionized air is not irradiated at the upper and lower ends. However, the static elimination effect is low, and it takes a long time to reliably eliminate static electricity from the upper and lower ends. Ru. According to actual measurements, β1−β2=25°.

[0021] In order to increase the amount of air blown from the ventilation hole 6, as shown in FIG. The base end opening 4b of the material 4 may be expanded in the vertical direction to introduce a large amount of air. .

[0022]

[Effect of the idea]

According to the static eliminator of the present invention, the ionized air generated inside the device is allowed to rise through the ventilation hole. The air is projected downward at intervals, and the blow direction control member swings up and down. move. Therefore, there is no blind spot for ionized air to the parts to be neutralized, and the ionized air are projected almost simultaneously onto the entire surface of the parts to be neutralized. This makes it possible to handle large parts to be neutralized. Even when removing static electricity, the processing time can be reduced to about 1/10 or less compared to conventional methods, making it easier to remove static electricity. It is also possible to eliminate work losses in the manufacturing process of necessary parts and materials. .
