Description

LED water level sensor for plating bath}

The present invention relates to an LED water level sensor for a plating tank, and more specifically, to an LED water level sensor for a plating tank which can easily transmit the low and high water level status of a plating tank to a work manager, and which has a simple structure, low manufacturing cost, and easy maintenance.

Typically, devices that plate metals such as copper or zinc on a surface have a plating tank filled with plating liquid, and the product to be plated is immersed in the plating liquid and the plating process is performed.

The plating solution in the plating tank of a plating device like this evaporates as the plating process progresses, and some of it is discharged by contaminating the product being plated, so it gradually decreases over time.

Therefore, there are cases where the plating solution needs to be replenished into the plating tank as needed.

In the past, to satisfy such a need, a level sensor measured the level of the plating solution in the plating tank, and the plating solution was supplied to the plating tank manually or automatically based on the measured level of the plating solution.

However, several water level detection sensors were used as a means of measuring the water level of the plating solution used in these devices.

Examples of water level detection sensors used include beam sensors, floating valves, and level switches.

However, when using a floating valve, the floating valve is located inside the plating tank, so it is not only difficult to install, but also difficult to maintain, and it is difficult for managers to detect the water level.

According to one embodiment of the present invention, a plating bath LED water level sensor (1000) is provided with power (1111) through a power supply connection port (1110) as illustrated in FIGS. 1 to 4, and includes a tubular translucent top cap (1100) that is closed at one end and open at the other end so that the lighting state can be checked when an LED lamp (1500) installed inside is turned on, a tubular top housing (1200) that is inserted from the other end of the top cap (1100) toward the center of the axis and is positioned at a predetermined position with a certain gap from the upper part of the top gap, and has an outer circumference formed in a stepped shape while having a relay receiving groove (1210) formed at one end forming the upper part, and a relay (1300) that is fitted and accommodated in the upper relay receiving groove (1210) of the top housing (1200), and is connected to the power supplied to the top cap (1100) and It includes a printed circuit board (1400) connected to a relay (1300), fixed to the upper surface of the relay (1300), mounted on the upper end of the top housing (1200), mounted at an axial predetermined position of the top cap (1100), and having an LED lamp (1500) and a control unit (1600) mounted on the upper surface, a pipe member (1700) having one end fitted to the outer surface of the axially reduced end of the top housing (1200) and the other end fitted to the top cap (1100) and having a pipe shape of a predetermined length according to the depth of a plating tank (not shown), and a float water level sensor (1900) assembled to the other end of the pipe member (1700) and capable of being selectively separated and connected to the relay (1300) so as to be able to transmit a detection signal for detecting the water level of the plating tank through the control unit.

Accordingly, when the float level sensor (1900) assembled on the lower side of the pipe member (1700) recognizes the low and high water levels of the plating tank, the relay (1300) causes the LED lamp (1500) to glow red or blue, respectively, through the control unit (1600) fixed to the printed circuit board (1400), and is displayed through the top cap (1100), so that the worker can easily identify the high and low water levels of the plating tank according to the glowing color of the LED lamp (1500), thereby improving the working environment.

That is, when the float switch (1910) and magnet (1912) inside the float level sensor (1900) are positioned at high and low water levels when the float (1910) rises and falls, a detection signal is sent to the control unit (1600) via the float wire (1950) and the printed circuit board wire (1410) described later, and the control unit (1600) switches the relay switch (1320) of the relay (1300) so that the LED lamp (1500) lights up in blue or red (red) depending on the assembly direction of the magnet (1912) described later.
That is, the magnet (1912) of the float (1910) that is assembled so as not to fall out by the stop ring (1920) while being fitted into the float housing (1930) is connected by switching the relay switch (1320) of the relay (1300) according to the assembly direction in which it is positioned up and down, so that the LED lamp (1500) lights up in blue or red.

Accordingly, when the float (1910) is located at a high or low water level and sends a detection signal to the control unit (1600), the control unit (1600) switches the relay switch (1320) of the relay (1300) so that the LED lamp (1500) lights up in blue or red, thereby improving visibility so that the high and low water levels of the plating tank can be easily identified based on the emitted color of the LED lamp (1500), thereby improving the working environment.

Here, the printed circuit board (1400) and the fixed relay (1300) are sealed and fixed in the relay receiving groove (1210) of the top housing (1200), and the pipe member (1700) and the top housing (1200) are also sealed and fixedly assembled, while the other end of the top cap (1100) is assembled so that the pipe member (1700), the top housing (1200), the relay (1300), and the printed circuit board (1400) can be separated at the same time.

Accordingly, when the LED lamp (1500) breaks down, the pipe member (1700), top housing (1200), relay (1300), and printed circuit board (1400) can be removed from the top cap (1100), and the broken LED lamp (1500) or other parts can be immediately separated and replaced from the upper surface of the printed circuit board (1400), making maintenance and inspection of the LED water level sensor (1000) for plating very easy.

In addition, the printed circuit board wire (1410) connected to the printed circuit board (1400) and connected to the flute wire (1950) described later may be connected downward through a gap between the side of the relay (1300) and the relay receiving groove (1210), or may be formed through a separate wire escape hole in the top housing (1200) and drawn downward to be connected to the flute wire (1950).

In addition, a bottom housing (1800) is further provided that is inserted in a sealed state with one end in a stepped state at the other end of the above-mentioned pipe member (1700) and penetrates through the center of the shaft, and the upper part of a float level sensor (1900) that is connected to the center of the shaft of the bottom housing (1800) is selectively connected.

Therefore, it becomes easy to assemble the float level sensor (1900) to the lower part of the pipe member (100) through the bottom housing (1800).

In addition, the float level sensor (1900) is a publicly known float (1910) that can move up and down according to the water level of the plating tank and has a magnet (1912) inside, a stop ring (1920) that is detachably attached to the bottom so that the float can be selectively removed to the bottom, a float housing (1930) that is detachably attached to the center of the axis of the bottom housing (1800) at the upper end and has the stop ring detachably assembled to the lower end while the float (1910) is assembled to be movable up and down in the axial direction and has a float switch (1911) connected to the magnet (1912) inside, a packing (1940) that is attached to the upper end of the float housing (1930) so that it is not loosened from the bottom housing (1800), and It consists of a flute wire (1950) of a certain length connected to a float housing (1930).

Accordingly, when the float (1910) in the float housing (1930) moves up and down according to the water level of the plating tank and reaches the high and low water levels, when the float (1910) moves toward the high water level, the internal magnet (1912) is at the position of the float switch (1911), and the float switch (1911) is connected, and the color of the LED lamp (1500) is made to glow in blue or red through the control unit (1600) and the relay (1300) via the float wire (1950) and the printed circuit board wire (1410), and when the stop ring (1920) is separated and the float (1910) is inserted into the float housing (1930) so that the upper and lower sides are switched, the blue or red color of the light changes.

The embodiments of the present invention described above and illustrated in the drawings should not be construed as limiting the technical idea of the present invention. The protection scope of the present invention is limited only by the matters described in the claims, and those with ordinary knowledge in the technical field of the present invention can improve and change the technical idea of the present invention in various forms. Accordingly, such improvements and changes will fall within the protection scope of the present invention if they are obvious to those with ordinary knowledge.
