Description
AUTOMATIC DIGITAL WELDING HELMET USING CAMERA Technical Field
[1] The present invention relates, in general, to an automatic digital welding helmet using a camera and, more particularly, to an automatic digital welding helmet using a camera, which photographs welding or cutting surroundings, and allows a worker to perform welding work while viewing moving images received from the camera, thus safely protecting the worker's eye. Background Art
[2] Conventionally, in order to adjust the shielding of harmful rays that are generated by welding or cutting torches, a welding helmet, with which an antiglare plate having variable light transmissivity is provided, has been used.
[3] That is, in the conventional welding helmet, a light sensor is mounted, and the light transmissivity of the antiglare plate is adjusted according to the intensity of welding light, thus protecting a worker's eyes.
[4] However, when the actual intensity of welding light is weak but the intensity of interference light is strong due to interference light that is generated in surroundings, not based on the welding light, the light transmissivity of the antiglare plate is lowered, so that a faulty operation in which an object to be welded may not be clearly observed occurs frequently.
[5] Furthermore, inconvenience occurs in that the worker must personally adjust the degree of shade of the antiglare plate and the sensitivity of the light sensor to be appropriate to welding surroundings.
[6] Furthermore, an inevitable problem occurs in that the harmful rays cannot be completely blocked and some of the harmful rays are incident on the worker's eyes even though the light transmissivity of the antiglare plate is appropriately adjusted to the welding surroundings.
[7] Furthermore, in the case of welding in air tank, high-pressure gas and aerospace fields, welding errors occasionally result in large-scale accidents, such as explosions. In cases where welding is critical, a problem occurs in that the weld condition must be confirmed later but it consumes time and cost to personally travel to an actual work site and confirm the weld condition. Disclosure of Invention Technical Problem
[8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide an automatic digital welding helmet using a camera, which allows a worker to perform welding work while viewing the moving images of the welding work, which are received from the camera, using a Liquid Crystal Display (LCD) monitor, so that harmful rays are completely blocked and errors caused by interference light do not occur.
[9] Another object of the present invention is to provide an automatic digital welding helmet using a camera, which stores the moving images of welding work in memory, and allows weld condition to be confirmed later using the memory in the case of critical welding work, thus detem-ining whether weld condition is faulty.
[10] A further object of the present invention is to provide an automatic digital welding helmet using a camera, which stores the identification number of the welding helmet along with the moving images of the welding work in memory, and allows the weld condition and the worker who performs corresponding welding work to be determined later. Technical Solution
[11] In order to accomplish the above objects, the present invention provides an automatic digital welding helmet using a camera, including a monitoring unit for monitoring welding work using a camera selected from among a plurality of cameras; a control unit for selecting any one from among the plurality of cameras, and storing moving images, which are received from the selected camera, in memory; and a display unit for displaying the moving images received from the selected camera.
[12] Furthermore, it is preferable that the monitoring unit include a first camera for photographing a front scene, a second camera for photographing a left side scene, a third camera for photographing a right side scene, a fourth camera for photographing an upper scene, and a fifth camera for photographing a lower scene.
[13] Furthermore, it is preferable that the first to fifth cameras each have a zoom function.
[14] Furthermore, the monitoring unit may be mounted on the outer side of the welding helmet, and the display unit may be mounted on the inner side of the welding helmet.
[15] Furthermore, the automatic digital welding helmet further may include an opening and closing unit mounted on the welding helmet to be openable, wherein the monitoring unit is mounted on the outer side of the opening and closing unit, and the display unit is mounted on the inner side of the opening and closing unit.
[16] Furthermore, it is preferable that the displaying unit indicates which camera be selected from among the plurality of cameras.
[17] Furthermore it is preferable that the display unit be a LCD monitor.
[18] Furthermore, it is preferable that the control unit include a camera selection module for selecting any one from among the plurality of cameras through a camera selection button, and a moving image storage module for storing the moving images, which are received from the camera selected by the camera selection module, in the memory when a moving image storage switch is turned on.
[19] Furthermore, it is preferable that the camera selection module be mounted on the outer side of the welding helmet.
[20] Furthermore, it is preferable that the moving image storage module store an identification number of the welding helmet along with the moving images in the memory.
[21] Furthermore, it is preferable that the memory be detachably attached to the welding helmet.
[22] Furthermore, it is preferable that the automatic digital welding helmet further include a light mounted on the outer side of the helmet.
[23] Furthermore, it is preferable that the automatic digital welding helmet further include a light on and off switch mounted on the outer side of the helmet.
[24] Furthermore, it is preferable that the control unit further comprise a wireless transmission and reception module for wirelessly transmitting the moving images received from the camera. Advantageous Effects
[25] Since, the automatic digital welding helmet using a camera according to the present invention allows a worker to perform welding work while viewing the images of the welding work, which are received from the camera, using an LCD monitor, harmful rays are completely blocked and errors caused by interference light do not occur at all.
[26] Furthermore, since the automatic digital welding helmet using a camera according to the present invention can store the images of the welding work in memory, weld condition can be confirmed later using the memory in the case of critical welding work, thus determining whether the weld condition is faulty.
[27] Furthermore, since the automatic digital welding helmet using a camera according to the present invention can store the identification number of the welding helmet along with the images of the welding work in the memory, the weld condition and the worker who performed corresponding welding work can be determined.
[28] Furthermore, since the automatic digital welding helmet using a camera according to the present invention allows the worker to select any one from among cameras for photographing front, left side, right side, upper, and lower scenes, the worker's view can be secured by selecting an appropriate camera in the case in which an object to be welded is placed at a corner location to which the worker's head cannot turn.
