According to various embodiments, the tap hole inspection device 10 may automatically inspect whether the tap hole 21 of the external structure 20 (eg, a mobile bracket) is good or bad. For example, the tap hole inspection device 10 fixes the external structure 20 and arranges the center and position of the tap hole of the external structure 20 and the tool 210 of the tool module 200 on the same line. Then, it relates to an integrated electronic device that automatically determines the state of the tap hole 21 through fastening and disconnection of the tool 210.

It may be a default value including the like.

According to an embodiment, the tool of the tool module may set rotation information and the like for each type of tool so that the process of fastening and/or separating the tool from the tapped hole of the external structure can be accurately performed. The tool setting information (eg, first data) is compared with the tool setting information (eg, second data) generated during actual fastening and/or separation by the sensor to determine whether the tapped hole state is good or bad. It can be used as data for judgment.

After the first data of the tool module is set, the operator may perform a process of seating and moving the external electronic device on the seating part (S20).

According to various embodiments, the mounting portion may be disposed on one surface of the housing of the main body and made of a metallic and/or plastic material. For example, the seating portion may be formed to be movable on an upper side of the housing. The seating unit may include a seating surface on which an external structure requiring inspection (eg, a bracket of an external electronic device) may be seated, and a movable member capable of moving the external structure seated on the seating surface to a space where an inspection is set. there is.

For example, the fixing member includes a first fixing member and a second fixing member, the first fixing member operates to support the upper bezel area of the external structure, and the second fixing member operates to support the lower bezel area of the external structure. It can act to support the area. The operation of the fixing member may be performed separately or simultaneously, and may be automatically controlled by a control circuit or manually controlled by a user.

As another example, the sensor may detect 1/2 rotation of the tool module through rotation of two protruding parts disposed on a straight line (eg, disposed at intervals of 180 degrees) about the rotation axis. The sensed information may be transmitted to the control circuit. As another example, the sensor may detect 1/4 rotation of the tool module through rotation of four protruding parts disposed at 90 degree intervals around the rotation axis, and transmit the detected information to the control circuit. can

According to various embodiments, the control circuit may provide an audible and/or visual notification to the operator when the tool module operates out of preset rotation information. For example, the control circuit may receive information such as rotation amount (number), rotation direction, rotation speed, or torque of the tool of the tool module in real time from the sensor unit, and transmits information such as preset information and If the comparison is out of the set information range, a signal (eg, abnormal signal) can be delivered to the operator audibly through an alarm. As another example, when the tool module operates out of the set range, a signal (eg, an abnormal signal) that can be visually detected by an operator may be transmitted through a data output unit or a lamp. An audible signal such as the alarm and a visual signal through a data output unit and/or a lamp may be provided separately or simultaneously. As another example, when the tool module operates within the set range, an audible and/or visual signal distinguished from an abnormal signal may be transmitted.

The tap hole inspection apparatus further comprising a no-load cylinder providing a no-load fastening process between the tool module and the tap hole of the external structure.
According to claim 10,
In the unloaded cylinder, when the end of the tool and the tapped hole come into contact, the operation of the conveying unit is stopped and the tool rotates and descends into the tapped hole only by rotation through a spring balance in the unloaded cylinder. Featured tap hole inspection device.
delete delete In the tool module included in the tap hole inspection device,
A tool for fastening and separating the tapped hole formed in the external structure;
a tool coupling member supporting at least a portion of the tool and rotatable in response to rotation of the tool;
a rotating member including an inner space into which the tool and the tool coupling member are inserted and connected to a driving motor providing rotational driving force to the tool module; and
Includes; a cover member for covering the coupling member together with the rotating member,
The rotating member,
a coupling portion including the inner space and an opening for exposing the inner space; and
Including at least one protruding portion protrudingly disposed on the upper end of the coupling portion,
The protruding portion is rotationally driven in response to rotation of the rotating member, and a sensor disposed adjacent to the tool module detects rotation of the protruding portion.
delete delete In the tapped hole inspection method,
setting first data including rotational information of a tool to be engaged with and separated from a tapped hole formed in an external structure;
a step of seating the external structure on a seating portion and moving it to an inspection space;
moving a tool module including the tool so that the tool faces the tapped hole of the external structure;
coupling and separating the tool and the tapped hole according to the movement or rotation of the tool module;
a process of sensing a movement or rotation of the tool module by a sensor disposed adjacent to the tool module and transmitting a signal corresponding to the movement to a control circuit; and
The control circuit compares and determines the first data and second data corresponding to the signal received from the sensor, and outputs whether the tapped hole is good or bad,
In the process of fastening the tool and the tap hole according to the movement or rotation of the tool module,
a first inspection process in which the tool module descends toward the tapped hole; and
and a second inspection step in which, when the tool contacts the tapped hole, the tool is fastened into the tapped hole only by rotation through a spring balance in the unloaded cylinder.
delete 18. The method of claim 17, wherein in the step of comparing and determining the first data and the second data by the control circuit,
comparing a rotational speed range or rotational speed range of the tool set in the first data with a rotational speed range or rotational speed range of the tool indicated in the second data; and
When the second data signal range is located within the first data set range, the state of the tapped hole is judged to be good, and when the second data signal range is located outside the first data set range, the state of the tapped hole is determined to be good. A method for inspecting a tapped hole inspection device, comprising: a step of determining a defect.
The method of claim 19, in the step of outputting whether the tapped hole is good or bad,
When the state of the tap hole of the external structure is determined to be good, a first signal is transmitted to the operator by sight or hearing, or when the state of the tap hole of the external structure is determined to be poor, a second signal to the worker by sight or hearing Tapped hole inspection device inspection method characterized in that for transmitting.
