Problems solved by technology

However, in these devices, the irradiation head needs a mechanism for installing an inert gas injection port, which complicates the structure somewhat and increases the size of the device.
In addition, the cable connecting the controller and the irradiation head needs a gas pipe for sending inert gas in addition to the optical fiber, and the cable becomes multiple or thicker, and the operability of the irradiation head connected to the optical cable deteriorates.

Embodiment 1

[0133] figure 1 It is a block diagram of the ultraviolet radiation apparatus of Example 1 of this invention. In the ultraviolet irradiation device 100 shown in the figure, the controller unit 110 and the irradiation head 120 are connected by a cable unit 130 . A semiconductor element that emits ultraviolet rays for curing the ultraviolet curable resin is incorporated in the irradiation head 120 . The controller unit 110 has a power supply unit 112, a control unit 114, and a storage unit 116 for driving the semiconductor elements of the irradiation head 120, and sends a driving signal (electrical signal) of the semiconductor elements to the irradiation head 120 through the cable unit 130. . In this figure, only one irradiation head 120 is connected to the controller unit 110, but as described later, a plurality of irradiation heads may be connected to the controller unit, and the ultraviolet irradiation conditions can be set independently. In addition, the ultraviolet irradi...

Embodiment 2

[0247] In addition, instead of forming a common setting unit as in the first embodiment, an individual setting switch 290 and an individual display unit 292 may be provided for each irradiation head. Figure 17 It is the front view of the controller part 210 of the ultraviolet irradiation apparatus of Example 2 of this invention. The individual setting switch 290 shown in this figure can be used to set the output power of ultraviolet rays irradiated from each irradiation head or increase or decrease the irradiation time, and an up / down switch or the like can be used. In this embodiment, the ultraviolet irradiation conditions of each channel can be set by the individual setting switch 290 , and the ultraviolet irradiation conditions can also be set using the operation panel 244 . In addition, it is also possible to omit the general-purpose operation panel and perform setting only by the individual setting switch.

[0248] A 7-segment display or the like can be used as the inde...

Embodiment 3

[0250] In addition, an individual setting switch and an individual irradiation switch for adjusting the ultraviolet output of each irradiation head may be provided in the irradiation head 120 instead of the controller part 110 . Figure 18 ~ Figure 19 It is the irradiation head 320 of the ultraviolet irradiation device of Example 3 of the present invention. As shown in these figures, an individual irradiation switch 380 for starting / stopping ultraviolet irradiation from the UVLED 350 and an individual setting switch 390 for adjusting an ultraviolet output level are provided on the irradiation head 320 . The individual setting switch 390 may adopt an up / down switch composed of two push button switches. Such as Figure 18 (b) and Figure 19 These switches are mounted on circuit boards as shown. Other components may be used and the described image 3 and so on for the same structure. This structure can be used well in such a way that the output can be adjusted by the movemen...

Abstract

PROBLEM TO BE SOLVED: To individually set ultraviolet conditions irradiated by multiple head sections. ŽSOLUTION: A device of irradiating an ultraviolet comprises: a plurality of head sections 120 equipped with one or more semiconductor devices capable of irradiating the ultraviolet as an ultraviolet source; and a controller section 110. The controller section 110 is provided with: a memory 116 for respectively storing a plurality of ultraviolet irradiation conditions set by a setting section 140; a setting mode for setting the ultraviolet conditions; and a controller 114 which can switch an irradiation mode irradiating the ultraviolet by a console panel 144 and calls the ultraviolet irradiation conditions stored in the memory 116 at the time of the irradiation mode and controls the semiconductor devices of the head sections 120 in accordance with the ultraviolet irradiation conditions setting. The irradiation mode further includes a batch irradiation mode irradiating the ultraviolet from all the head sections 120 and an individual irradiation mode irradiating the ultraviolet from specific head sections 120.
