Description

The present invention relates to a power supply device for a light irradiator that supplies a drive current in a desired manner to a light irradiator used for surface inspection, exposure, and the like.

This type of power supply device for a light irradiator (hereinafter, also simply referred to as a power supply device) is connected to the light irradiator via a current supply cable extending from the front, and supplies a drive current for lighting to the light irradiator. be. Further, a panel portion for operation or display is provided on the front surface of the power supply device. For example, by operating the panel portion, the mode of the drive current, that is, the amount of current or the voltage value, or The waveforms of these change, and the amount of light and the timing of light emission of the light irradiator can be adjusted.

However, such a light irradiator and a power supply device are deployed in a factory or the like, and the arrangement location and the routing of the current supply cable may be restricted in relation to other equipment.

For example, when it is desired to pull out the current supply cable from the back side of the power supply device, since the current supply cable comes out from the front as described above, it may be difficult to handle the current supply cable. Of course, it can be handled by separately preparing a model in which the current supply cable extends from the back, but that would increase the number of product types and impose a burden on manufacturing.

In addition, when using multiple light irradiators regardless of the same type or different types, or when adding light irradiators, power supply devices are required for each number of light irradiators, but each power supply device has a panel. Therefore, if this panel part can be shared, it can contribute to space saving and price reduction.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the LED light irradiation system 200 according to the present embodiment supplies power to a light irradiator 300 for surface inspection or exposure using an LED as a light source, and the light irradiator 300 to light the light. It is equipped with a power supply device 100 for a light irradiator (hereinafter, also simply referred to as a power supply device 100).

The light irradiator 300 has an LED 301 as a light source inside, and the anode and cathode of the LED 301 are used as current input terminals.

The power supply device 100 supplies a current for lighting to the light irradiator 300 via a current supply cable C, and has a capacity and a capacity depending on various light irradiators 300 having different numbers of LEDs and the like. Multiple types with different output voltage, output current, etc. are available.

The power supply device 100 taken up in this embodiment is one of them, and as shown in FIGS. 2, 3 and the like, two units, a subunit 2 and a main unit 1, are connected and configured.

As shown in FIGS. 2 to 4, the subunit 2 includes a housing 21, a power supply circuit 22 housed therein, and a current supply connector 23 to which the current supply cable C is detachably connected. It is equipped with. Since there are a plurality of types and a plurality of types of light irradiators 300 that can be connected to the subunit 2, a plurality of types and a plurality of types of current supply connectors 23 are provided here corresponding to the plurality of types.

The housing 21 is made of metal having a rectangular parallelepiped shape.

Physically speaking, the power supply circuit 22 is formed by mounting various electric components on a printed substrate 22c as shown in FIG. 4, and in terms of circuit, as shown in FIG. 2, is commercially available. The AC-DC converter 22a that converts alternating current supplied from the AC power supply to direct current, and the amount of current and voltage value output from the AC-DC converter 22a can be changed, or the waveform can be changed to a rectangular wave or the like. The light irradiator 300 is provided with an output circuit 22b that outputs an LED drive current. Then, the mode of the LED drive current output from the output circuit 22b, that is, the light emission mode such as the light amount and the light emission timing of the light irradiator 300 is determined by the current amount, the voltage value, the waveform, and the like.

As shown in FIGS. 3 and 5, the current supply connector 23 is provided on the front surface of the housing 21, and the current supply cable C extending from the light irradiator 300 is connected to the current supply connector 23. By doing so, the LED drive current output from the output circuit 22b is supplied to the light irradiator 300.

On the other hand, as shown in FIGS. 2, 3 and the like, the main unit 1 includes a housing 11, a control circuit 12 housed therein, and a panel unit 13.

The housing 11 is made of a rectangular parallelepiped metal, and in this embodiment, the housing 11 is set to have at least the same depth and height as the housing 21 of the subunit 2.

Physically speaking, the control circuit 12 has various electronic components such as a CPU, a memory, and a DA converter mounted on a printed circuit board (not shown), and functionally speaking, it is stored in the memory. By operating according to the program, as shown in FIG. 2, a setting signal that determines a current supply mode is transmitted to the output circuit 22b. It should be noted that a CPU and a memory are not always required, and these may be assembled by a discrete circuit, or an FPGA or the like may be used.

As shown in FIGS. 2, 3 and the like, the panel unit 13 is provided on the front surface of the housing 11. Here, the panel unit 13 is composed of a digital panel meter and various operation keys, and the panel unit 13 is operated by operating the panel unit 13. , It is possible to set a light emitting mode related to the light amount, the light emitting timing, and the like of the light irradiator 300. In this embodiment, as shown in FIG. 2, the control circuit 12 reads the setting content input and operated by the panel unit 13, generates a setting signal according to the setting content, and outputs the setting signal 22b. Send to. The output circuit 22b sets the mode of the LED drive current to be output according to the content of the setting signal.
The panel unit 13 may be, for example, a touch panel or the like, or may be provided with only a display unit indicating an operating status such as an operating lamp or a set current value. In that case, the setting signal may be received from another terminal device or the like.

However, in this embodiment, as shown in FIGS. 3, 5 and the like, the first connector 1a for transmitting the setting signal is provided on one side surface of the main unit 1. Further, a second connection connector 2a for receiving the setting signal is provided on both side surfaces of the subunit 2.

The first connection connector 1a and the pair of second connection connectors 2a are arranged at the same height, and here, they are arranged at the center of the housings 11 and 21 in the depth direction. .. In FIG. 5, these connectors 1a and 1b are simply represented by triangular irregularities in order to avoid complication.

By the way, as shown in FIG. 4, the second connection connector 2a is connected to the printed circuit board 22c in the housing 21 by, for example, a cable, and as shown in FIG. 6, each second connection is made. In the connector 2a, the terminals are wired so that the order of the terminals is reversed in the front-rear direction. In the figure, the numbers in the connector indicate the terminal numbers.

In this embodiment, the first connection connector 1a and the second connection connector 2a are directly connected to each other in a rigid manner, and by this connection, the housings 11 and 12 are positioned relative to each other while their side surfaces are adjacent to each other or close to each other. Are mechanically connected so that they are invariant.

Further, due to the configuration in which the second connector 2a is provided on both side surfaces of the subunit 2, as shown in FIG. 7, one side surface of the subunit 2 with respect to the first connector 1a of the main unit 1. When the second connector 2a provided in the above is connected, the units 1 and 2 are integrally connected in a state where the front surfaces thereof are all on the front side and are substantially flush with each other.

On the other hand, when the second connector 2a provided on the other side surface of the subunit 2 is connected, the front surface of the main unit 1 and the back surface of the subunit 2 are on the front side, and the front surface and the back surface thereof are on the front side. The units 1 and 2 are integrally connected in a flush state.

However, in such a case, since the subunit 2 can be attached to the main unit 1 in either the front or rear direction, the outlet of the current supply cable C can be set in either the front or the back. .. Therefore, for example, it becomes possible to realize the optimum routing of the current supply cable C according to the equipment layout in the factory.

Moreover, since the units 1 and 2 are mechanically connected to each other only by connecting the connectors 1a and 2a, it does not take much time to connect them.

Further, regardless of which direction the subunit 2 is attached to the main unit 1 in the front-rear direction, the front and back surfaces of the power supply device 100 as a whole are substantially flush with each other, and the contour shape does not change, that is, the footprint. And the height does not change. Therefore, even if the arrangement space of the power supply device 100 is limited and then the front-rear direction of the subunit 2 has to be changed for some reason, there is no problem.

The present invention is not limited to the above embodiment.

For example, the first connection connector 1a may be provided on both side surfaces of the main unit 1. In this case, the option that the subunit 2 can be connected to either the left or right side of the main unit 1 increases, and the flexibility for the limitation of the equipment layout is further increased.

Further, as described above, when the first connection connector 1a is provided on both side surfaces in the main unit 1, the subunit 2 is provided with the second connection connector 2a only on one side surface thereof. You may leave it. Even in this way, the subunits 2 can be connected by changing the front and back.

In the above-described embodiment, in the subunit 2 connected / connected to the main unit 1, the unconnected second connection connector 2a remains in the open state, but as shown in FIGS. 8 and 9. Here, a subunit 2'of another type (hereinafter, also referred to as a second subunit 2'. Further, the subunit of another type referred to here is different in any one of the form, the current supply capacity, the current supply mode, and the like. It does not matter if it is possible to connect / connect.
A first connector 1a provided on the main unit 1 is provided on one side surface of the second subunit 2', and is connected to the second connector 2a provided on the subunit 2. You can do it.

At this time, it is preferable that the setting signal from the main unit 1 is output so that the one for the subunit 2 and the one for the second subunit 2'can be distinguished. For example, in the panel unit 13, when transmitting a setting signal to the subunit 2 and the second subunit 2', after inputting predetermined identification numbers to the subunit 2 and the second subunit 2', respectively. , The amount of light and the like may be set so that the amount of light and the like of each subunit 2 and 2'are set separately.

Further, in FIGS. 8 and 9, the second connector 2a is provided on the other side surface of the second subunit 2'. With such a second subunit 2', the front-back positional relationship with respect to the subunit 2 cannot be changed, but as shown in FIG. 10A, the second subunit 2'is connected one after another. be able to. Further, as shown in FIG. 10B, one or more second subunits 2'can be connected to the main unit 1, and the subunit 2 can be further connected to the outside thereof.

Further, a plurality of types of subunits 2 in which the second connector 2a is provided only on one side surface may be prepared.
In such a case, a plurality of types of subunits 2 can be mutably attached to the main unit 1 while the front and rear of the main unit 1 cannot be changed.

Therefore, if the user only needs to prepare one main unit 1, for example, even if the light irradiator 300 is replaced with another one and the corresponding power supply device 100 is required, only the subunit 2 is required. Can be replaced with the corresponding type, and the cost can be reduced.

In addition, a part of various embodiments may be combined and modified as long as it does not contradict the gist of the present invention.
