Description

Multi-wavelength UV LED conveyor system

[0001] This application claims the benefit of priority from Republic of Korea Patent Application No. 10-2023-0197749, filed December 29, 2023, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to an ink curing conveyor having a detachable structure for LED modules using UV-LEDs (ultra-violet light emitting diodes) that generate ultraviolet rays of different wavelengths, an elevating structure for an elevating body of the LED modules, a conveyor having the elevating body, and a controller installed so as to be docked to the conveyor.

[0003] Conventional ink curing testers were equipped with only a single-wavelength UV LED, a UV curing device installed above the conveyor. Therefore, using a different wavelength curing device required the hassle of replacing the entire curing device.

[0004] Furthermore, conventional curing machines were designed to accommodate only single-wavelength UV LEDs, making it impossible to simultaneously irradiate UV light of different wavelengths. Consequently, testing the simultaneous use of UV light of various wavelengths, which could be combined to shorten process times, was impossible.

[0005] Additionally, special care was required in handling the relevant parts when replacing damaged LED modules, and training for this maintenance task was required.

[0006] Meanwhile, conventional ink curing testers required the cumbersome task of loosening and tightening bolts each time the LED module's distance from the subject was adjusted. Furthermore, this height adjustment method occupied space within the conveyor, necessitating the placement of a separate controller for controlling the LED module.

[0007] The present invention has been devised to solve the above-described problem, and aims to provide an ink curing conveyor capable of simultaneously using ultraviolet rays of various wavelengths, thereby enabling testing of an optimal combination of ultraviolet wavelengths for shortening process time.

[0083] Referring to FIGS. 1 to 4, the ink curing conveyor of the embodiment includes a conveyor (10) capable of movably mounting an object to be irradiated in a first direction (D1). A curing device (30) that irradiates ultraviolet rays toward the object to be irradiated is installed on the upper portion of the conveyor (10). The irradiation direction of the ultraviolet rays is downward. That is, the curing device (30) irradiates ultraviolet rays downward.

[0084] A case (40) that accommodates the curing device (30) is fixed to the conveyor (10) to limit the irradiation space of ultraviolet rays irradiated from the curing device (30). A door (41) is installed at the front of the case (40) to allow a user to access the curing device (30) from the front of the conveyor (10).

[0085] The above-mentioned curing device (30) is electrically connected to a controller (20) that controls the operation of the LED module (74). The conveyor (10) has a receiving portion (12) in which the controller (20) is dockably received. Accordingly, the controller (20) can be installed without the hassle of providing a separate space for arranging the controller (20). The controller (20) can control the operation of not only the curing device (30) but also the conveyor (10).

[0086] A control panel (80) capable of inputting data via a display touch panel is installed at the upper front of the conveyor (10). The control panel (80) can control the hardener (30) and the conveyor (10) independently or in conjunction with the controller (20).

[0087] At the upper part of the conveyor (10), an elevator device (50) is arranged to adjust the height of the hardener (30) relative to the conveyor (10).

[0088] Referring to FIGS. 5 to 7, the lifting device (50) has a fixed part (51) fixed to the frame of the conveyor (10), an elevating part (60) installed to be able to be lifted and lowered on the fixed part (51), and an adjusting part (52, 53, 54) for adjusting the height of the elevating part (60).

[0089] The above control unit (52, 53, 54) is installed in the above fixed unit (51).

[0090] The above-mentioned control unit (52, 53, 54) is provided with a ball screw (54) extending in the vertical direction, a handle (53) installed at the upper end of the ball screw to rotate the ball screw, and a locker (52) installed at the upper end of the ball screw to prevent rotation of the ball screw.

[0091] In the above lifting unit (60), a block (65) that engages with the ball screw is provided so that it can be raised and lowered in conjunction with the rotation of the ball screw.

[0092] The above-mentioned hardener (30) has an elevating body (61) connected to the elevating part (60). The above-mentioned ultraviolet module (70) is installed at the bottom of the above-mentioned elevating body (61).

[0093] As illustrated in FIGS. 1 to 3, the handle (53) and the locker (52) of the control unit (52, 53, 54) are exposed from the upper portion of the case (40). Since the curing device (30) irradiates ultraviolet rays downward, even if a portion of the upper portion of the case (40) is opened and the handle (53) and the locker (52) are exposed through this, there is no concern that ultraviolet rays will leak through this.

[0094] When the user releases the locker (52) and turns the handle (53) to one side, the hardener (30) rises, and when the user turns the handle (53) to the other side, the hardener (30) descends. When the user locks the locker (52), the handle (53) cannot rotate, and thus the height of the hardener (30) is fixed.

[0095] According to an embodiment, by placing the lifting device (50) on the upper part of the conveyor (10), a space can be provided inside the conveyor (10) in which the controller (20) can be docked and installed.

[0096] Meanwhile, the width of the fixing member (51) is adjustable so that it can be installed on various conveyors (10) having different widths. Referring to Fig. 5, the fixing member (51) has a rail-shaped width adjustment member (55) extending parallel to the width direction of the conveyor (10), and a slider (56) having a fixing portion that can be fixed to the conveyor (10) is connected to the width adjustment member (55) so as to be able to slide. Of course, by adjusting the position of the slider (56) and then fixing the slider (56) to the width adjustment member (55), the slider (56) can be prevented from sliding relative to the width adjustment member (55).

[0097] Referring to FIGS. 8 to 11, a plurality of ultraviolet modules (70) are aligned in a first direction (D1) and are detachably installed at the bottom of the curing device (30). Each of the plurality of ultraviolet modules (70) has a module body (71) in which an LED module (74) is built.

[0098] An alignment protrusion (72) is provided on one side of the module body (71) of each of the above UV modules (70) in the first direction. In addition, an alignment groove (73) having a shape complementary to the alignment protrusion (72) is provided on the other side of the module body (71) in the first direction opposite to the alignment protrusion (72). Accordingly, the UV modules (70) can be easily aligned in the first direction, and an error of connecting the polarity in the opposite direction during the power connection process of the LED module (74) to which DC power is supplied can be prevented. The embodiment exemplifies that the shapes of the alignment protrusion (72) and the alignment groove (73) are equilateral trapezoids.

[0099] The first wavelength of ultraviolet light irradiated from an LED module (74) built into at least one ultraviolet module (70) among the plurality of ultraviolet modules (70) is different from the second wavelength of ultraviolet light irradiated from an LED module (74) built into another ultraviolet module (70).

[0100] The first wavelength and the second wavelength of the above ultraviolet rays may be different wavelengths selected from among 255 nm, 275 nm, 340 nm, 365 nm, 375 nm, 385 nm, and 395 nm.

[0101] On the bottom surface of the above UV module (70), a window (77) is installed through which the UV rays emitted from the LED module (74) can pass. The material of the window (77) may be, for example, quartz or monomer PMMA. Accordingly, the user can prevent accidental contact with the components or lenses of the LED module (74).

[0102] According to the embodiment, the external dimensions of the UV modules (70) are the same, but the wavelengths of the UV rays irradiated from the LED modules (74) inside them are different. Therefore, UV modules (70) that generate UV rays of different wavelengths can be installed at any location on the bottom of the curing device (30).

[0103] Referring to FIGS. 10 to 13, the ultraviolet module (70) and the curing device (30) are each provided with a power connection structure that is interconnected.

[0104] The above power connection structure includes a pair of banana plugs (62) extending downward from the bottom of the curing device (30), and a pair of banana sockets (75) provided in the ultraviolet module (70) so that each of the banana plugs (62) is inserted.

[0105] The above banana plug (62) and banana socket (75) provide a locking force that restricts relative longitudinal movement when inserted longitudinally. Accordingly, it may be easier for the user to attach the UV module (70) to the bottom of the curing device (30).

[0106] A space is provided at the bottom of the module body (71) of the above UV module (70) to accommodate the LED module (74). The banana socket (75) extends downward from the top of the module body (71) through the module body (71) and the LED module (74), and is fastened to a nut (76) at the bottom of the LED module (74). Accordingly, the LED module (74) is tightly fixed to the module body (71), and the opening direction of the fastening hole of the banana socket (75) is aligned so that it faces upward. The module body (71) can be made of a material with high thermal conductivity so as to quickly dissipate heat generated from the LED module (74).

[0107] A removal groove (78) is provided at the upper end of the second direction end of the ultraviolet module (70) that intersects both the first direction and the irradiation direction. The removal groove (78) allows the user to easily remove the ultraviolet module (70) from the lifting body (61) of the curing device (30) despite the pre-fastening force.

[0108] Referring to Fig. 10, the ultraviolet module (70) and the curing device (30) are each provided with a fastening structure for fastening them to each other.

[0109] The above-mentioned connection structure is provided independently from the above-mentioned power connection structure.

[0110] The above-mentioned fastening structure includes a first fastening hole (721) provided in the alignment protrusion (72) at one end in the first direction of the module body (71), and a second fastening hole (731) provided at a position outside the alignment groove (73) at the other end in the first direction.

[0111] In response to this, the fastening structure includes a third fastening hole (63) and a fourth fastening hole (64) provided at the bottom of the curing device (30) so as to correspond to the positions of the first fastening hole (721) and the second fastening hole (731), respectively. In the second direction, the positions of the first fastening hole (721) and the third fastening hole (63) are arranged to be offset from the positions of the second fastening hole (731) and the fourth fastening hole (64). Therefore, there is no concern that the fastening direction of the ultraviolet module (70) will be aligned in the opposite direction.

[0112] Referring to FIGS. 11, 14, and 15, a first light sensor (742) and a second light sensor (13) are installed in the curing machine (30) and the conveyor (10), respectively. The first light sensor (742) is installed in each LED module (74) together with an LED light source (741) that emits ultraviolet rays. The light-receiving direction of the first light sensor (742) is parallel to the light-emitting direction of the light source (741). The second light sensor (13) is installed in a guide portion that guides the movement of the belt on both sides of the belt of the conveyor (10). The light-receiving direction of the first light sensor (742) may face downward, and the light-receiving direction of the second light sensor (13) may face upward.

[0113] Referring to FIGS. 16 to 19, the control panel (80) displays a screen that can be controlled via a display. In addition, the user can control each function and monitor the operating status of the curing device (30) by touching the touch panel.

[0114] Referring to Fig. 16, the control panel (80) can display the light quantity and temperature for each channel of each LED module (74) and can display the status of the cooling device. In addition, it can display the power usage and the operating time of the light source (741). As illustrated in Fig. 17, the control panel (80) can provide a control screen that can adjust the light quantity of the LED module (74) of each channel. In addition, the control panel (80) can measure the intensity and irradiance of ultraviolet rays measured from the light sensors (742, 13) as illustrated in Fig. 18. As illustrated in Fig. 19, the user can monitor the status of each channel through the control panel (80).

[0115] In accordance with the spirit of the embodiments described above, it is self-evident that various modifications to them are possible, and it is self-evident that a person skilled in the art who understands the above embodiments can easily make such modifications.

[0116] Although the present invention has been described with reference to the drawings exemplified above, it is to be understood that the present invention is not limited to the embodiments and drawings disclosed herein, and that various modifications may be made by those skilled in the art within the scope of the technical idea of ​​the present invention.
