[0041] The detailed description and technical content of the present utility model will be described below in conjunction with the drawings. However, the attached drawings are only for illustrative purposes and are not intended to limit the present utility model.

[0042] Refer to Figure 1 As shown, an embodiment of the present utility model provides a color grain transfer device, which is used to transfer at least two color grains 21 carried on a transparent film 20 to a circuit board 10. In this embodiment, the color grain transfer device includes a base 100, a first translation mechanism 210, a second translation mechanism 220, a frame 300, a color discrimination and recognition module 400, and a pressing member mechanism 500.

[0043] Just as the base 100 is used to carry the circuit board 10, the present utility model does not limit the form of the base 100. Specifically, the top surface of the base 100 has a working plane. The circuit board 10 has a transfer surface 11, and at least two circuits are printed and arranged on the transfer surface 11, thereby defining at least two transfer positions 12. The circuit board 10 is placed flat on the working plane and the transfer surface 11 is arranged upward.

[0044] The first translation mechanism 210 is disposed on the base 100, and the second translation mechanism 220 is disposed on the first translation mechanism 210. The second translation mechanism 220 can be driven by the first translation mechanism 210 to move parallel to the working plane.

[0045] As Figures 1 to 4As shown, the frame 300 is disposed on the first translation mechanism 210 and suspended above the base 100, and the frame 300 can be driven by the first translation mechanism 210 to move parallel to the working plane. The frame 300 is used to carry the transparent film 20, and the frame 300 has a window 301 for the side of the transparent film 20 where the color grains 21 are located to face the circuit board 10 and to place the color grains 21 within the window 301.

[0046] As Figures 1 to 4 shown, the color discrimination and recognition module 400 is suspended above the frame 300. In this embodiment, the color discrimination and recognition module 400 is disposed on the second translation mechanism 220 and suspended above the window 301. Therefore, the color discrimination and recognition module 400 can be driven by the second translation mechanism 220 to move, and at least a part of the downward projection range of the color discrimination and recognition module 400 is located within the window 301.

[0047] As Figure 1 and 5 shown, the pressing member mechanism 500 is disposed on the second translation mechanism 220 and suspended above the window 301. As Figure 6 and Figure 7 shown, the pressing member mechanism 500 generally includes a thimble disposed downward and an actuator for driving the thimble to move up and down. Specifically, at least one of at least two red grains 21r, at least two green grains 21g, and at least two blue grains 21b is included among at least two color grains 21. These color grains 21 can be carried on the same transparent film 20 or separately carried on at least two transparent films 20 by color separation.

[0048] Referring to Figures 1 to 4 , in this embodiment, the color grain transfer device of the present invention further includes a calibration component 600, and the calibration component 600 is directly fixed on the working plane of the base 100. The calibration component 600 includes a high-reflectivity calibration sheet 610 and a low-reflectivity calibration sheet 620. The high-reflectivity calibration sheet 610 is light-colored such as white or metallic, and the low-reflectivity calibration sheet 620 is dark-colored such as black. The base 100 can be made of metal, so a part of the working plane can also serve as the high-reflectivity calibration sheet 610.

[0049] Referring to Figures 1 to 8 and Figure 11 , in this embodiment, the color grain transfer method of the present invention is performed by the foregoing color grain 21 transfer device to transfer the grains 21. The color grain transfer method of the present invention includes the steps described below.

[0050] First, in step a, provide the circuit board 10 as described above and the transparent film 20 carrying at least two color crystals 21 as described above, and configure the side of the transparent film 20 where the color crystals 21 are located to face the transfer surface 11 of the circuit board 10.

[0051] Subsequently, in step b following step a, provide the color discrimination and recognition module 400 as described above. First, relatively move the color discrimination and recognition module 400, the frame 300, and the calibration component 600 so that the recognition module, the window 301, and the calibration component 600 are aligned in sequence from top to bottom. In this embodiment, the first translation mechanism 210 moves the frame 300 and the second translation mechanism 220 above the calibration component 600, thereby making the calibration component 600 within the projection range below the window 301. According to requirements, the second translation mechanism 220 can be further used to move the color discrimination and recognition module 400 so that the recognition module, the window 301, and the calibration component 600 are aligned in sequence from top to bottom. Therefore, when the color discrimination and recognition module 400 reads the color crystals 21 in the window 301, the color discrimination and recognition module 400 can simultaneously read the calibration component 600 through the window 301. That is to say, the color discrimination and recognition module 400 can read the color crystals 21 with the calibration component 600 as the background. Specifically, the light reflectivity of the red crystals 21r is relatively low, and with the high-reflectivity calibration sheet 610 as the background, the red crystals 21r can be highlighted to facilitate the color discrimination and recognition module 400 to identify the positions of the red crystals 21r. Also, the light reflectivities of the green crystals 21g and the blue crystals 21b are relatively high, and with the low-reflectivity calibration sheet 620 as the background, the green crystals 21g and the blue crystals 21b can be highlighted to facilitate the color discrimination and recognition module 400 to identify the positions of the green crystals 21g and the blue crystals 21b.

[0052] Specifically, the frame 300 can be driven by the first translation mechanism 210 to move above the calibration component 600, and the color discrimination and recognition module 400 can be driven by the second translation mechanism 220 to make the window 301 located between the color discrimination and recognition module 400 and the calibration component 600, and the color discrimination and recognition module 400 can read the calibration component 600 through the window 301.

[0053] Subsequently, in step c following step b, provide the pressing mechanism 500 as described above, and configure the pressing mechanism 500 corresponding to the other side of the transparent film 20 opposite to the color crystals 21; and

[0054] Subsequently, in step d following step c, move the transparent film 20 to align one of the color crystals 21 on the transparent film 20 with the corresponding transfer position 12 on the circuit board 10, move the pressing mechanism 500 to align its ejector pin with the transfer position 12, and drive the ejector pin downward by the actuator to make the pressing mechanism 500 press the transparent film 20 to transfer the color crystal 21 to the transfer position 12, and repeat this sequentially for each color crystal 21.

[0055] Specifically, after the position of the color crystal grains 21 is identified, the first translation mechanism 210 moves the frame 300 so that the color crystal grains 21 to be transferred are moved above the corresponding transfer position 12. Then, the first translation mechanism 210 moves the pressing member mechanism 500 above the aforementioned transfer position 12 and presses down to press the color crystal grains 21 to be transferred onto the corresponding transfer position 12 on the circuit board 10, as Figure 9 shown.

[0056] Refer to Figures 5 to 11 , another embodiment of the present utility model provides a color crystal grain transfer device, which is used to transfer at least two color crystal grains 21 carried on a transparent film 20 to a circuit board 10. Referring back to Figures 5 to 8 , in this embodiment, the color crystal grain transfer device, like the previous embodiment, includes a base 100, a first translation mechanism 210, a second translation mechanism 220, a frame 300, a color discrimination and recognition module 400, and a pressing member mechanism 500. Specifically, at least two of the at least two color crystal grains 21 include at least one color among at least two red crystal grains 21r, at least two green crystal grains 21g, and at least two blue crystal grains 21b. These color crystal grains 21 can be carried on the same transparent film 20, or can be separately carried on at least two transparent films 20 by color.

[0057] The base 100 is used to carry the circuit board 10, and the present utility model does not limit the form of the base 100. Specifically, the top surface of the base 100 has a working plane. The circuit board 10 has a transfer surface 11, and there are at least two transfer positions 12 on the transfer surface 11. The circuit board 10 is placed flat on the working plane and the transfer surface 11 is configured upward.

[0058] The first translation mechanism 210 is arranged on the base 100, and the second translation mechanism 220 is arranged on the first translation mechanism 210. The second translation mechanism 220 can be driven by the first translation mechanism 210 to move parallel to the working plane.

[0059] The frame 300 is arranged on the first translation mechanism 210 and is suspended above the base 100, and the frame 300 can be driven by the first translation mechanism 210 to move parallel to the working plane. The frame 300 is used to carry the transparent film 20, and the frame 300 has a window 301 for the side of the transparent film 20 where the color crystal grains 21 are located to face the circuit board 10 and be located within the window 301.

[0060] The color discrimination and recognition module 400 is suspended above the frame 300. In this embodiment, the color discrimination and recognition module 400 is disposed on the second translation mechanism 220 and suspended above the window 301. Therefore, the color discrimination and recognition module 400 can be driven by the second translation mechanism 220 to move, and at least a part of the downward projection range of the color discrimination and recognition module 400 is located within the window 301.

[0061] The pressing member mechanism 500 is disposed on the second translation mechanism 220 and suspended above the window 301. The pressing member mechanism 500 generally includes a thimble disposed downward and an actuator for driving the thimble to move up and down.

[0062] Refer to Figure 9 and Figure 10 In this embodiment, the difference from the previous embodiment is that the color crystal grain transfer device of the present invention further includes a calibration component 600, and the calibration component 600 is movably disposed on the base 100. Specifically, the color crystal grain transfer device of the present invention further includes a third translation mechanism 230, the third translation mechanism 230 is disposed on the base 100, and the calibration component 600 is disposed on the third translation mechanism 230 and can be moved by the third translation mechanism 230. The calibration component 600 includes a high-reflection calibration sheet 610 and a low-reflection calibration sheet 620. The high-reflection calibration sheet 610 is light-colored such as white or metallic color, and the low-reflection calibration sheet 620 is dark-colored such as black.

[0063] In this embodiment, the color crystal grain transfer method of the present invention is performed by the foregoing color crystal grain transfer device to transfer the color crystal grains 21. The color crystal grain transfer method of the present invention includes the steps described below.

[0064] First, in step a, a circuit board 10 as described above and a transparent film 20 carrying at least two color crystal grains 21 as described above are provided, and the surface of the transparent film 20 where the color crystal grains 21 are located is disposed facing the transfer surface 11 of the circuit board 10.

[0065] Continuing from step a, in step b, the aforementioned color discrimination and recognition module 400 is provided to identify the positions of the respective colored crystal grains 21 on the transparent film 20 by means of the color discrimination and recognition module 400. The specific description is as follows. First, the color discrimination and recognition module 400, the frame 300, and the calibration component 600 are relatively moved so that the recognition module, the window 301, and the calibration component 600 are aligned in sequence from top to bottom. In this embodiment, the third translation mechanism 230 moves the calibration component 600 to within the projection position range below the window 301. Therefore, when the color discrimination and recognition module 400 reads the colored crystal grains 21 in the window 301 through the transparent film 20 in the window 301, the color discrimination and recognition module 400 can simultaneously read the calibration component 600 through the transparent film 20 in the window 301. That is to say, the color discrimination and recognition module 400 can read the colored crystal grains 21 with the calibration component 600 as the background. Specifically, the light reflectivity of the red crystal grains 21r is relatively low, and with the high-reflectivity calibration sheet 610 as the background, the red crystal grains 21r can be highlighted to facilitate the color discrimination and recognition module 400 to identify the positions of the respective red crystal grains 21r. Also, the light reflectivities of the green crystal grains 21g and the blue crystal grains 21b are relatively high, and with the low-reflectivity calibration sheet 620 as the background, the green crystal grains 21g and the blue crystal grains 21b can be highlighted to facilitate the color discrimination and recognition module 400 to identify the positions of the respective green crystal grains 21g and the respective blue crystal grains 21b.

[0066] Continuing from step b, in step c, the aforementioned pressing mechanism 500 is provided, and the pressing mechanism 500 is arranged to correspond to the other side of the transparent film 20 opposite to the colored crystal grains 21; and

[0067] Continuing from step c, in step d, the transparent film 20 is moved so that one of the colored crystal grains 21 on the transparent film 20 is aligned with the corresponding transfer position 12 on the circuit board 10, and the pressing mechanism 500 is moved so that its ejector pin is aligned with the transfer position 12, and the actuator drives the ejector pin downward to press the transparent film 20 with the pressing mechanism 500 to transfer the colored crystal grain 21 to the transfer position 12, and this is repeatedly performed sequentially for each colored crystal grain 21.

[0068] Specifically, after the position of the colored crystal grain 21 is identified, the first translation mechanism 210 moves the frame 300 so that the colored crystal grain 21 to be transferred is moved above the corresponding transfer position 12. Then, the first translation mechanism 210 moves the pressing mechanism 500 above the aforementioned transfer position 12 and presses down to press the colored crystal grain 21 to be transferred onto the corresponding transfer position 12 on the circuit board 10, as Figure 9 shown.

[0069] For the colored crystal grain transfer device and the colored crystal grain transfer method of the present utility model, after the color discrimination and recognition module 400 identifies the positions of the colored crystal grains 21, it can align with the transfer position 12 through the first translation mechanism 210 and the second translation mechanism 220, and quickly transfer the colored crystal grains 21 with the pressing mechanism 500.
