Description

Apparatus For Inspecting And Adjusting Lantern}

The present invention relates to a lantern inspection and adjustment device, and more specifically, to a lantern inspection and adjustment device that allows inspection of a lantern and adjustment of luminous intensity to be performed conveniently and quickly.

Lanterns used by firefighters when extinguishing fires are differentiated from lanterns for the general public in terms of function, reliability, and durability.

Therefore, these fire lanterns undergo a thorough investigation during the production process, and further go through a process of setting them up individually to standardize the product (whether the expected illuminance can be achieved at a specific level).

This work was previously performed manually, which required manpower and time, reducing work productivity. The background of this problem is explained in more detail as follows.

Even when lanterns are manufactured by assembling the same parts, the intensity of illumination varies slightly. Among the reasons why the lantern's illuminance varies slightly, the important ones are that, firstly, there is a difference in precision among the LED elements supplied from one place, which are the light source of the lantern, and secondly, the reflector, which has a significant effect on the illuminance, cannot be manufactured exactly the same. There is none.

Therefore, it is necessary to pre-set the illuminance of each lantern being produced. Previously, two people worked as a team to measure the illuminance and set the lantern manually. However, as mentioned, this work not only requires two workers to work together, but also requires a considerable amount of time.

Hereinafter, specific details of the present invention will be described in detail with reference to the accompanying drawings. In particular, where necessary, explanations will be made by citing specific drawings.

The lantern inspection and adjustment device according to the present invention includes a rotary table (10), a lantern mounting base (20), an illuminance meter installation base (60), a rotary table driving device (40), and a control unit.

The rotary table 10 is installed on the work table 30 so that it can rotate about an axis perpendicular to the ground. The installation height of the rotary table 10 is similar to the height of an office desk so that it is convenient for workers to work while sitting on a chair. A PC 31 with a built-in control program is installed on the work table 30 and functions as a control unit.

The rotary table 10 may be a circular table, but is not necessarily limited thereto. The rotary table 10 may be installed to be able to rotate 360°, or may be installed to be able to rotate back and forth only within a certain angle range.

A plurality of lantern mounting bases 20 are arranged along the circumferential direction on the upper surface of the rotary table 10, that is, in a fan shape. As shown, five lantern mounting bases 20 are installed, but this is only an example.

The lantern seat 20 includes a lantern seat 21 that can seat the lantern 1 in an accurate position, and a clamp-type fixing mechanism 22 for fixing the lantern seated in the lantern seat 21. Includes. When the lantern 1 is placed on the lantern mounting base 21, a terminal 23 that is electrically connected to the circuit within the lantern 1 may be installed. Using this terminal 23, signals can be transmitted and received between the lantern 1 and an external device (i.e., PC 31). The lantern seating portion 21 is in the form of a groove so that the lower end of the lantern 1 is inserted.

The rotary table driving device 40 rotates the rotary table 10 about a vertical axis and can be installed at the bottom of the top plate of the work table 30. The rotary table driving device 40 may include a servo motor and an electric mechanism. The rotary table driving device 40 intermittently rotates the rotary table 10 by the arc angle K at which the lantern mounting base 20 is spaced each time the operator presses a button.

The illuminance meter installation stand 60 is installed spaced apart in front of the rotary table 10. The illuminance meter installation stand 60 and the work table 30 may be connected by a floor frame 50. A horizontal rail 51 is installed on the floor frame 50, and the illuminance meter installation stand 60 can be moved horizontally along this horizontal rail 51. A scale indicating the distance may be provided on the horizontal rail 51. Using this scale, the distance between the illuminance meter 70 and the lantern 1 can be adjusted accurately and quickly.

The floor frame 50 is installed horizontally spaced apart from the ground by legs 52.

The illuminance meter installation stand 60 consists of a base 61 mounted on the floor frame 50 and a post 63 installed upright at the center of the base 61.

The shortest straight line distance (L) between the lantern 1 mounted on the lantern mounting base 20 and the illuminance meter 70 installed on the illuminance meter installation stand 60 is determined by KS standards or the orderer's request. Therefore, this distance (L) can be adjusted depending on the situation or the specifications of the lantern.

The illuminance meter 70 is installed on the illuminance meter installation stand 60 and measures the illuminance of light emitted from the rotary table 10. The height of the illuminance meter 70 is adjustable along the vertical rail 61 installed on the illuminance meter installation stand 60. A scale for measuring the height of the illuminance meter 70 may also be installed on the illuminance meter installation stand 60.

The value measured by the illuminance meter 70 is transmitted to the worker's PC 31 as an electrical signal. In other words, if the required value is not obtained according to the specified standard, the operator corrects the program inside the lantern so that the specified value is obtained by increasing the signal level of the lantern (1). If the value is low, adjust in reverse. This work is performed using a PC (31) installed on the work table as a control unit.

Typically, the illuminance of the lantern 1 using an LED element may vary sensitively depending on the characteristics of the LED element or the state of a reflector installed in the lantern. For this reason, it is necessary to inspect all manufactured lanterns, inspect the illuminance, and then set the zero point of the lantern to achieve the specified performance.

The worker installs the lantern (1) on all lantern mounting bases (20) and inspects and corrects them one by one sequentially while rotating the rotary table (10). Afterwards, all lanterns that have been calibrated are removed and new ones are installed and worked in batches. In this way, one worker can perform work at high speed. Depending on the size of the rotary table 10, the number of lanterns that can be installed at once may vary. What is shown in each drawing is only an example, and the scale of the rotary table 10 can be expanded so that 20 to 100 lanterns 1 can be installed at a time.

According to an embodiment of the present invention, a laser pointer 71 may be provided in the illuminance meter 70 so that the positional relationship between the illuminance meter 70 and the lantern 1 can be conveniently determined. By using the laser light of this laser pointer (71), it is easy to accurately adjust the horizontal height and left/right spacing between the illuminance meter (70) and the lantern (1).

Hereinafter, another embodiment of the present invention will be described with reference to FIG. 6. This embodiment is intended to further increase work speed by expanding the number of lanterns 1 that can be installed at once. According to this embodiment, the rotary table 10 is installed in a multi-layer structure using a shelf 80. According to this embodiment, the worker first inspects the lantern 1' on the lower floor, then increases the height of the illuminance meter 70 and then inspects the lantern 1" on the upper floor. Lower rotary table 10' and the upper rotary table (10") may be configured to rotate simultaneously to simplify the structure of the device, but may be rotated independently if necessary. According to this embodiment, twice as many lanterns can be installed and worked compared to the previous embodiment, so the work speed can be further increased. This embodiment implies that not only a two-story structure but also a three- or four-story structure is possible.

The configuration shown and described above is nothing more than a preferred embodiment based on the technical idea of the present invention. Those skilled in the art will be able to make various changes based on common technical knowledge, but it should be noted that these may be included in the scope of protection of the present invention. The embodiments disclosed above may be combined in various ways, and all possible combinations are within the scope of the present invention.
