[0032] Hereinafter, a preferred embodiment of the corona discharge test device according to the present invention will be described in detail with reference to the attached drawings.

[0034] FIG. 1 is a perspective view illustrating one embodiment of the corona discharge test device of the present invention, FIG. 2 is a drawing illustrating an example of the combination of the mounting bar and the probe module of the corona discharge test device of the present invention, FIG. 3 is a drawing illustrating one embodiment of the probe module of the corona discharge test device of the present invention, FIG. 4 is a drawing illustrating another embodiment of the probe module of the corona discharge test device of the present invention, FIG. 5 is a drawing illustrating the bottom surface of the probe module of FIG. 4, FIG. 6 is a drawing illustrating the mounting member of the mounting bar and the probe module according to one embodiment of the corona discharge test device of the present invention, FIG. 7 is a drawing illustrating the mounting bar according to another embodiment of the corona discharge test device of the present invention, and FIG. 8 (a) and (b) are drawings illustrating various shapes of the mounting bar and the mounting member according to another embodiment of the corona discharge test device of the present invention.

[0036] The present invention relates to a corona discharge test device (50) that can be easily replaced with a probe module corresponding to the area of ​​the corona discharge treatment target, and as shown in FIG. 1, the configuration may include a height adjustment unit (100) installed inside a chamber (10), an installation bar (200) installed to be vertically movable on the height adjustment unit (100), and a probe module (300) installed on the installation bar (200).

[0037] To explain in more detail, the chamber (10) has a sealable space in which the remaining components can be installed, and a door (12) is provided on one side.

[0038] Additionally, the chamber (10) is provided with a gas injection valve (14) for injecting a reaction gas used during corona discharge and a gas discharge valve (16) for discharging the reaction gas on one side, and each valve is connected to a gas tank (not shown).

[0039] And, a support plate (20) on which a discharge treatment target is placed is provided on the bottom surface of the chamber (10).

[0040] At this time, the support plate (20) can be installed so as to be movably installed on the rail (22) and can be installed so as to be pulled out to the outside of the chamber (10) to facilitate the installation of the discharge treatment target.

[0042] Meanwhile, the height adjustment unit (100) may include an adjustment screw (110) installed vertically inside the chamber (10).

[0043] The above adjustment screw (110) has screw threads formed on its outer surface, and the above installation bar (200) has a through hole formed on its inner surface to which the adjustment screw (110) is coupled.

[0044] Therefore, when the adjustment screw (110) is rotated while the adjustment screw (110) is coupled to the through hole of the installation bar (200), the installation bar (200) moves in the longitudinal direction of the adjustment screw (110), thereby allowing the height of the installation bar (200) to be adjusted.

[0045] At this time, the handle of the control screw (110) is installed to be exposed to the outside of the chamber (10), so that the control screw (110) can be operated even when the chamber (10) is sealed with a reaction gas injected into it.

[0046] Additionally, a guide rod (120) may be further provided parallel to the adjustment screw (110), and a through hole is formed in the installation bar (200) to which the guide rod (120) can be coupled.

[0047] Therefore, when the installation bar (200) moves up and down by the above adjustment screw (110), it is guided by the above guide rod (120) so that the installation bar (200) does not move during the up and down movement and can be moved stably.

[0049] Meanwhile, the above-mentioned installation bar (200) is formed in a bar shape and may be provided with a concave seating groove (210) so that a probe module (300) to be described later can be seated on the upper surface.

[0050] At this time, it is preferable that the seating groove (210) is formed to correspond to the shape and size of the part of the probe module (300) to be seated, so that the probe module (300) does not move when seated.

[0051] Additionally, the above-mentioned mounting groove (210) may have a coupling groove (212) formed therein to which a fixing member is coupled so that the probe module (300) can be fixed by a fixing member such as a bolt, pin, or rivet.

[0052] Here, the probe module (300) is formed with a through hole through which a fixing member, such as a bolt, pin, or rivet, passes.

[0053] Additionally, the above-mentioned installation bar (200) may be provided with a vibration-damping member (220) in the above-mentioned seating groove (210).

[0054] The above vibration damping member (220) is made of a silicone pad or the like, which has elasticity, and by absorbing the vibration generated during discharge by the above vibration damping member (220), the vibration of the probe (340) provided in the probe module (300) can be minimized, thereby having the effect of maintaining high accuracy during micro-discharge operation.

[0055] Additionally, as shown in FIG. 6, the installation bar (200) may have a positioning projection (230) further formed on the side where the seating groove (210) is formed.

[0056] Additionally, the probe module (300) may have a positioning groove (314) formed therein corresponding to the positioning projection (230).

[0057] Therefore, when the above probe module (300) is coupled to the above installation bar (200) and spans the seating groove (210), if the positioning projection (230) enters the above positioning groove (314), it is possible to know that it has entered the position corresponding to the seating groove (210), and by lowering the above probe module (300) and seating it in the seating groove (210), the probe module (300) can be easily installed in the correct position.

[0058] Here, it is preferable that the positioning groove (314) is formed in the vertically elongated shape of the probe module (300) so that when the probe module (300) is lowered after the positioning projection (230) enters the positioning groove (314), the probe module (300) can descend vertically and stably without deviating from the corresponding position.

[0059] Additionally, one or more of the above-mentioned mounting grooves (210) may be formed in the installation bar (200) along the length direction of the installation bar (200).

[0060] Therefore, the installation location of the probe module (300) installed on the above-mentioned installation bar (200) can be selected, and multiple probe modules (300) can be installed by installing the probe module (300) in one or more of the mounting grooves (210), and thus, it can be arranged in various forms as needed.

[0061] At this time, the remaining components, the coupling groove (212), the vibration damping member (220), and the positioning projection (230), may be formed or installed to correspond to each seating groove (210).

[0063] Meanwhile, as illustrated in FIG. 7, the installation bar (200') may be configured to be adjustable in length, and the installation bar (200') may include a first body (200A) installed on the height adjustment unit (100) and a second body (200B) coupled to the first body (200A) and installed to be movable in the longitudinal direction of the first body (200A).

[0064] Here, the remaining configuration of the installation bar (200') configured as above is the same as that of the previously described embodiment, so a detailed description thereof will be omitted.

[0065] However, the adjustment screw (110) and guide rod (120) may be installed through the first body (200A) of the above-mentioned installation bar (200'), and the seating groove (210), coupling groove (212), vibration damping member (220), and positioning projection (230) may be formed in the second body (200B).

[0066] At this time, the first body (200A) may be provided with an insertion member (202) protruding therefrom, and the second body (200B) may be formed with an insertion groove (204) into which the insertion member (202) is inserted.

[0067] Therefore, by adjusting the degree to which the insertion member (202) is inserted into the insertion groove (204), the total length of the installation bar (200') can be adjusted, and as a result, the position of the seating groove (210) formed in the second body (200B) can be appropriately set.

[0068] Here, the insertion member (202) and the insertion groove (204) are formed in a polygonal shape, so that when adjusting the position between the insertion member (202) and the insertion groove (204), the second body (200B) is prevented from rotating around the insertion member (202) as an axis and can move stably in the horizontal direction.

[0069] Additionally, although not illustrated, after adjusting the degree to which the insertion member (202) is inserted into the insertion groove (204), a separate fixing member such as a bolt, pin, or rivet is passed through the outside of the second body (200B) to fix the insertion member (202), thereby allowing the adjusted length to be maintained.

[0071] Meanwhile, the probe module (300) may include a closed-loop shaped mounting member (310) having a through hole (312) through which the mounting bar (200, 200') passes, an electrode plate (320) installed at the bottom of the mounting member (310), and a fixing chuck (330) provided on the electrode plate (320) to which a probe (340) is coupled.

[0072] At this time, the mounting member (310) is made of an insulator, so that when electricity is supplied to the electrode plate (320) at the bottom, electricity can be prevented from leaking through the mounting member (310).

[0073] In addition, it is preferable that the width of the through hole (312) of the mounting member (310) be formed to correspond to the width of the installation bar (200, 200') so as to prevent the mounting member (310) from moving when installed on the installation bar (200, 200'), and the aforementioned elongated positioning groove (314) may be formed on both sides of the through hole (312).

[0074] And, the electrode plate (320) has a power connection part (322) on one side so that it receives electricity and acts as a discharge electrode.

[0075] Additionally, as shown in FIGS. 3 and 4, the fixed chuck (330) on which the probe (340) is installed may be installed as one on the electrode plate (320), or multiple may be installed to form a certain area on the electrode plate (320).

[0076] Therefore, a probe module (300) equipped with a number of fixed chucks (330) suitable for the size of the discharge treatment target can be replaced and installed on the installation bar (200) for use.

[0077] At this time, when a plurality of fixed chucks (330) are installed to form a certain area on the electrode plate (320), each fixed chuck (330) installed on the electrode plate (320) may be spaced apart from an adjacent fixed chuck by a certain distance.

[0078] That is, as shown in FIG. 5, adjacent fixed chucks (330) are arranged to form an equilateral triangle, and fixed chucks (330) surrounding one fixed chuck (330) are arranged to form a hexagon, thereby having the effect of ensuring that the discharge is uniformly carried out over a wide area.

[0080] Meanwhile, although the cross-sectional view of the installation bar (200, 200') is depicted as square in FIGS. 1, 2, 6, and 7, as shown in FIGS. 8 (a) and (b), the cross-sectional view of the installation bar (200, 200') can be formed in various shapes such as polygons or circles.

[0082] Accordingly, the corona discharge test device (100) according to the present invention as described above has various advantages, such as being able to easily replace the probe module corresponding to the area of ​​the corona discharge treatment target, and being able to install multiple probe modules by providing a plurality of mounting grooves on the installation bar and installing a probe module in each mounting groove.

[0084] The above-described embodiments are explained with respect to the most preferred examples of the present invention, but are not limited to the above embodiments, and it is obvious to those skilled in the art that various modifications are possible within the scope of the technical spirit of the present invention.
