The present invention relates to a positioning system, and more particularly to a positioning system that can accurately position and position a mask on a substrate.

In the process of fabricating an LED (Light Emitting Diode) package structure, it is conventional to form a phosphor paste mixed with phosphor powder on a LED wafer by dispensing or spraying. In some spraying processes, the LED wafers are first bonded and then sprayed with a fluorescent colloid. Since the conventional spraying process uses a manual insertion mask to position and match the LED substrate carrying the LED chip, the mask easily touches the gold wire that has been completed and causes the wire to collapse, thereby leading to the LED package. The probability of structural reliability failure increases. Furthermore, if only a part of the LED wafer is subjected to the spraying process, the relationship between the mask and the LED substrate is not completely adhered to each other due to the micro-gap relationship between the mask and the LED substrate, thereby making the spraying process The fluorescent colloid is very easy to leak into the area where it has not been sprayed and has not been bonded by the solid crystal, which causes the subsequent wire bonding yield to decrease in the above-mentioned unfixed wire bonding region, so the LED package structure is subsequently implemented. The probability of disconnection during the thermal cycle reliability is very high.

[First Embodiment]

Referring to FIG. 1A to FIG. 1J, FIG. 1A to FIG. 1J are sequential diagrams showing the operation flow of the positioning system according to the first embodiment of the present invention. Hereinafter, the related operation flow of the positioning system of the first embodiment of the present invention will be described in sequence with reference to the drawings, but the operation flow is only used as an example, and of course all the related quantity definitions described below are also used as examples. It is not intended to limit the invention, but is hereby described.

First, as shown in FIG. 1A and FIG. 1B, a carrier 1 is first placed and positioned on a first working machine 2 (as shown in FIG. 1A), and then at least one is used to carry a plurality of light-emitting units L. The substrate S is placed and positioned on the carrier 1 (as shown in FIG. 1B).

For example, the carrier 1 can be positioned on the first work machine 2 through a plurality of positioning tabs B (eg, spacer elements such as bushings or bushings). In addition, the carrier 1 has at least two fixed positioning members 10 disposed approximately on the diagonal, and the substrate S has at least two substrates disposed approximately on the diagonal and corresponding to the at least two fixed positioning members 10, respectively. Positioning hole S10. As shown in FIG. 1A and FIG. 1B, when the substrate S is placed in a recess 12 formed in the carrier 1, at least two fixed positioning members 10 of the carrier 1 can pass through at least the substrate S, respectively. The two substrates are positioned in the hole S10, so that the substrate S can be easily and conveniently transmitted through the accommodation of the groove 12 and the use of the at least two fixed positioning members 10 to be accurately positioned on the carrier 1.

Furthermore, as shown in FIG. 1C and FIG. 1D, the first working machine 2 includes at least one movable unit 20, wherein the movable unit 20 can include at least two movable positioning members 20A and a plurality of movable supporting members 20B. The two movable positioning members 20A can be disposed on the diagonal line, and the movable positioning member 20A and the movable supporting member 20B can be accommodated in the first working machine 2, and can be selectively extended or retracted as needed. A working machine 2. When the at least two movable positioning members 20A and the plurality of movable supporting members 20B are simultaneously moved upward and respectively pass through the opening 11 of the carrier 1, the end portions of each of the movable positioning members 20A are movable with each The end portion of the support member 20B can be simultaneously disposed at a first position "for positioning the mask M over the substrate S". In other words, after the substrate S is positioned on the carrier 1 (as shown in FIG. 1B ), the first working machine 2 firstly moves at least two movable positioning members 20A and a plurality of movable supports of the movable unit 20 . 20B simultaneously protrudes from the first working machine 2 (moves upward) to respectively pass through the opening 11 of the carrier 1 (as shown in FIG. 1C), and then at least one mask M corresponding to the substrate S is placed and It is positioned on the movable unit 20 (as shown in FIG. 1D).

For example, the mask M can be made of a magnetic material that has a high carbon content and is not easily rusted. The mask M has a cover M10 corresponding to the substrate S, a plurality of spray openings M11 penetrating the cover M10, at least two first masks penetrating the cover M10 and corresponding to the at least two movable positioning members 20A, respectively. The positioning hole M12 and the at least two second mask positioning holes M13 penetrating the cover M10 and corresponding to the at least two fixed positioning members 10 respectively. In addition, each of the movable positioning members 20A has a movable positioning body 201A that passes through the carrier 1 to press up against the bottom surface of the cover M10 and a first extending from the movable positioning body 201A and through the corresponding first mask. The positioning post 202A of the hole M12 is positioned, and each of the movable supporting members 20B has a movable supporting body 200B that passes through the carrier 1 to press up against the bottom surface of the cover M10. In addition, the distal end portion defined by the movable positioning member 20A includes the top end of the movable positioning body 201A and the entire positioning post 202A, and the end portion defined by the movable supporting member 20B is the top end of the movable supporting body 200B. In other words, the mask M can obtain a more balanced support effect not only through the support of the top end of each movable positioning body 201A and the top end of each movable support body 200B, but also the mask M can be connected via each one. The positioning post 202A at the top end of the movable positioning body 201A cooperates with each of the first mask positioning holes M12 to obtain a stable positioning effect. Thereby, since the mask M can be placed on the plurality of movable supporting members 20B, even if the thickness of the mask M is extremely thin, the mask M can be obtained through the use of the plurality of movable supporting members 20B. The multiple and uniform supporting force, in turn, allows the mask M to be effectively maintained in a horizontal state where no bending or bending occurs. In addition, since the positioning post 202A of each movable positioning member 20A can pass through the corresponding first mask positioning hole M12 of the mask M, the mask M can be easily and conveniently used through the plurality of movable supporting members 20B. To be accurately positioned on the movable unit 20.

In addition, as shown in FIG. 1D and FIG. 1E, the distal end portion of each of the movable positioning members 20A and the distal end portion of each of the movable supporting members 20B can be simultaneously disposed at one time for "passing the mask M through the at least two The fixed positioning member 10 is positioned at a second position on the substrate S. In other words, after the mask M has been placed and positioned on the movable unit 20 (as shown in FIG. 1D), at least two movable positioning members 20A and a plurality of movable supports 20B of the movable unit 20 are simultaneously retracted. The first working machine 2 (moving downward) is disengaged from the mask M, and the mask M can be matched with the at least two fixed positioning members 10 through the at least two second mask positioning holes M13. The mask M is positioned on the substrate S (as shown in FIG. 1E).

For example, the at least two second mask positioning holes M13 respectively correspond to the at least two fixed positioning members 10, and the at least two second mask positioning holes M13 respectively correspond to the at least two substrate positioning positions. a hole S10 (as shown in FIG. 1C or FIG. 1D), so when the at least two movable positioning members 20A and the plurality of movable supporting members 20B are simultaneously moved downward to disengage the mask M, the at least two fixed types are The positioning member 10 will be able to accurately pass through the at least two second mask positioning holes M13, respectively, so that the mask M can be easily transmitted through the use of the at least two fixed positioning members 10 to be accurately positioned on the substrate S. . In other words, since the “at least two second mask positioning holes M13 respectively correspond to the relationship of the at least two fixed positioning members 10 respectively”, the at least two movable positioning members 20A and the plurality of movable supports are At a moment when the member 20B is disengaged from the mask M, the at least two second mask positioning holes M13 can naturally be accurately passed by the at least two fixed positioning members 10, respectively, so that the mask M can be touched without being touched. When the blue light-emitting diode die L11 and its wire W (shown in FIG. 1H) have been touched in the light-emitting unit L, the at least two fixed positioning members 10 are naturally and naturally penetrated. Accurately positioning on the substrate S can also prevent the wire W of the blue light-emitting diode die L11 from collapsing, so that the primary wire yield of the blue light-emitting diode die L11 can be effectively improved.

In addition, as shown in FIG. 1E and FIG. 1F, when the mask M is accurately positioned on the substrate S through the at least two fixed positioning members 10 (as shown in FIG. 1E), an upper pressing plate P can be covered. The carrier 1 is pressed to press against the peripheral edge of the mask M (as shown in FIG. 1F). For example, the upper platen P includes a plate body P10 movably disposed on the carrier 1 and at least one window P11 penetrating the plate body P10. When the upper platen P is placed on the carrier 1, the plate P10 of the upper platen P can be used to press the peripheral edge of the mask M (that is, the peripheral edge of the cover M10), and the window P11 of the upper platen P can be used for bareness. The plurality of spray openings M11 described above. In addition, when the upper pressing plate P is covered on the carrier 1, the at least two fixed positioning members 10 can be respectively exposed to the two diagonal notches of the board P10.

Furthermore, as shown in FIG. 1F and FIG. 1G, when the upper pressure plate P is placed on the carrier 1 (as shown in FIG. 1F), the carrier 1 can be removed from the first working machine 2, and then The carrier 1 is positioned on a second working machine 3 at a predetermined distance from the first working machine 2 (as shown in FIG. 1G). For example, the carrier 1 can also be positioned on the second working machine 3 through a plurality of positioning protrusions B. In addition, the second working machine 3 includes an electromagnetic force generating module 30 for generating magnetic attraction and an electromagnetic force control module 31 for turning on or off the electromagnetic force generating module 30. Thereby, when the carrier 1 is positioned on the second working machine 3, the magnetic attraction force generated by the electromagnetic force generating module 30 can be transmitted (at this time, the electromagnetic force control module 31 is switched to the ON state, such as FIG. 1G) is such that the mask M having the magnetic attraction function can be closely adsorbed on the substrate S by the attraction of the magnetic attraction force generated by the electromagnetic force generation module 30. In other words, when the electromagnetic force control module 31 is switched to the ON state (as shown in FIG. 1G), the magnetic attraction force generated by the electromagnetic force control module 31 after the electromagnetic force generating module 30 is turned on is not only the mask M. It can be completely adhered to the substrate S so that the micro-gap between the cover M10 and the substrate S is less likely to infiltrate the phosphor colloid sprayed in the subsequent process, and at the same time, the platen P is also electromagnetically generated. The magnetic attraction generated by the group 30 is attracted to avoid contamination of the second working machine 3 by the phosphor colloid sprayed in the subsequent process due to penetration into the gap between the plate P10 and the mask M.

In addition, as shown in FIG. 1G, FIG. 1H, and FIG. 1I, when the carrier 1 is positioned on the second working machine 3, and the mask M is attracted by the magnetic attraction generated by the electromagnetic force generating module 30, After being closely adsorbed on the substrate S (as shown in FIG. 1G and FIG. 1H, wherein FIG. 1H is a partially enlarged schematic view of the mask M being closely adsorbed on the substrate S), the phosphor colloid C can be sprayed on the above-mentioned multiple A position where the spray opening M11 is exposed (as shown in FIG. 1I), wherein a region where the light-emitting unit L is exposed by the spray opening M11 is defined as a “primary-bonded wire region R1”, and the light-emitting unit L is not sprayed with the opening M11. The bare area is defined as "secondary bonding line area R2".

For example, as shown in FIG. 1H and FIG. 1I, each of the light-emitting units L includes two blues which are placed on the seed layer S11 of the substrate S and are respectively exposed by two corresponding spray openings M11. The light-emitting diode crystal grains L11 are disposed, and each of the blue light-emitting diode crystal grains L11 is electrically connected to the two electrodes S12 of the substrate S through two corresponding wires W. Thereby, when the phosphor colloid C is sprayed on the "primary solid wire bonding region R1" exposed by the above two corresponding spray openings M11, the phosphor colloid C will only cover the above two blue light emitting two The polar body L11 and its corresponding two wires W. Moreover, since the mask M can be completely adhered to the relationship on the substrate S, the micro-gap between the cover M10 and the substrate S is less likely to be infiltrated by the phosphor colloid C, so the fluorescent colloid C will not easily penetrate into the covered cover. The body M10 covers the place, thereby effectively improving the wire yield of the subsequent secondary line. In other words, during the spraying process of the phosphor colloid C, the phosphor colloid C will only cover the two blue LED dipoles L11 and their corresponding two wires W, and will not easily penetrate into the cover. Between the M10 and the substrate S, the glue overflows to the "secondary solid crystal wiring region R2", so that the yield of the subsequent secondary bonding can be effectively improved.

Furthermore, after the step of spraying the phosphor colloid C is completed, the electromagnetic force control module 31 is first switched to the OFF state to eliminate the magnetic attraction of the electromagnetic force generating module 30 to the carrier 1, and then the firefly has been completed. The photocolloid C sprayed carrier 1 is removed from the second working machine 3, and then the carrier 1 is again positioned on the first working machine 2, and the upper pressing plate P is opened (refer to FIG. 1F and FIG. 1E). Then, after the movable unit 20 is moved upward to lift the mask M, the mask M is removed (refer to FIG. 1D and FIG. 1C), and finally, after the movable unit 20 is moved downward, the mask can be smoothly removed. The substrate S of the above-mentioned fluorescent colloidal C spraying process has been completed (refer to FIG. 1B and FIG. 1A).

Finally, as shown in FIG. 1J, two red LED dipoles L12 are respectively placed on the seed layer S11 of the substrate S, and are passed through two corresponding wires W to be electrically connected to the substrate S. The other two electrodes S12. Since the phosphor colloid C during the spraying process is not easily spilled into the "secondary solid crystal wiring region R2", the secondary bonding yield of the subsequent red LED dipole L12 can be effectively improved.

In summary, the first embodiment of the present invention mainly provides a positioning system, which can be used to respectively locate at least one substrate S for carrying a plurality of light-emitting units L (shown in FIG. 1A to FIG. 1B) and to locate at least one. A mask M corresponding to the substrate S (in conjunction with FIG. 1C to FIG. 1E), wherein the positioning system comprises: a first working machine 2, a second working machine 3, and a carrier 1. The first working machine 2 includes at least one movable unit 20, wherein the movable unit 20 includes at least two movable positioning members 20A and at least two movable supporting members 20B. The second working machine 3 is at a predetermined distance from the first working machine 2. The carrier 1 is selectively positionable on one of the first working machine 2 and the second working machine 3, wherein the carrier 1 has at least two fixed positioning members 10, and the substrate S is permeable to the above At least two fixed positioning members 10 are positioned on the carrier 1, and the mask M is permeable to the substrate S through the at least two fixed positioning members 10.

First, for example, when the carrier 1 is positioned on the first work machine 2, the end portion of each of the movable positioning members 20A and the end portion of each of the movable support members 20B can be simultaneously disposed at one a first position for positioning the mask M above the substrate S (as shown in FIG. 1D), or may be simultaneously disposed at a direction for the mask M to pass through the at least two fixed positioning members 10 Positioned on the second position on the substrate S (as shown in FIG. 1E).

Further, for example, when the distal end portion of each of the movable positioning members 20A is simultaneously disposed at the first position with the distal end portion of each of the movable supporting members 20B (as shown in FIG. 1D), each of the movable positioning The movable positioning body 201A of the piece 20A can pass through the carrier 1 to press up against the bottom surface of the cover M10, and the positioning post 202A of each movable positioning member 20A can extend upward from the corresponding movable positioning body 201A and pass through the phase. Corresponding first mask positioning holes M12, and the movable support body 200B of each movable support 20B can pass through the carrier 1 to face up against the bottom surface of the cover M10.

Further, for example, when the distal end portion of each of the movable positioning members 20A is simultaneously disposed at the second position with the distal end portion of each of the movable supporting members 20B (as shown in FIG. 1E), each of the movable positioning members The end portion of the 20A and the end portion of each movable support member 20B are simultaneously separated from the mask M, so that each of the fixed positioning members 10 can sequentially pass through the corresponding substrate positioning hole S10 and the corresponding second cover. The cover is positioned to the positioning hole M13 to achieve the purpose of separately positioning the substrate S and the mask M.

It should be noted that, as shown in FIG. 1A and FIG. 1B, if both the fixed positioning member 10 and the substrate positioning hole S10 are designed to have mutually corresponding foolproof shapes (for example, all rectangular or any polygonal shape), the present invention can also The substrate S can be accurately positioned on the carrier 1 only by the cooperation of a single fixed positioning member 10 and a single substrate positioning hole S10. Of course, if a single fixed positioning member 10 is used together with the anti-slipping design of the groove 12, it is more ensured that the substrate S is placed in the correct position. In addition, as shown in FIG. 1C to FIG. 1E, since the present invention can also use only a single fixed positioning member 10, the mask M can also use only a single second mask positioning hole M13. When the second mask positioning hole M13 is designed to correspond to the foolproof shape of the single fixed positioning member 10, the mask M can also use only a single second mask positioning hole M13 to accurately position the mask M. The effect on the substrate S.

In other words, the carrier 1 can also have at least one fixed positioning member 10, and the substrate S can have at least one substrate positioning hole S10 corresponding to the at least one fixed positioning member 10, and the at least one mask M can also have at least one mask M. A mask positioning hole M13 corresponding to the at least one substrate positioning hole S10. Therefore, when the at least one fixed positioning member 10 sequentially passes through the at least one substrate positioning hole S10 and the at least one mask positioning hole M13, the substrate S can pass through the at least one fixing due to the above-mentioned foolproof design. The positioning member 10 is positioned on the carrier 1 , and the at least one mask M can be positioned on the at least one substrate S through the at least one fixed positioning member 10 .

[Second embodiment]

Referring to FIG. 2A to FIG. 2E , FIG. 2A to FIG. 2E are schematic diagrams showing the operation flow of the positioning system according to the second embodiment of the present invention. The related operation flow of the positioning system of the second embodiment of the present invention will be described in the following with reference to the drawings, but the operation flow is only used as an example, and of course all the related quantity definitions described below are also used as examples. It is not intended to limit the invention, but is hereby described.

First, as shown in FIG. 2A, a carrier 1 is first placed and positioned on a first working machine 2 (the placement and positioning manner can be similar to that shown in the first embodiment), and then at least one is used. The substrate S carrying the plurality of light-emitting units L is placed and positioned on the carrier 1, and then the at least one pick-up head 21 is used to prepare for picking up at least one mask M previously positioned in a first positioning frame 22. For example, the manner in which the mask M is sucked up may be vacuum suction or magnetic suction... and the like. The suction head 21 can perform any movement in the X direction or the Y direction through a three-dimensional working platform (not shown) disposed on the first working machine 2 (of course, the three-dimensional working platform can also be placed on the first working machine 2 Up, but placed at a predetermined position from the first working machine 2), and the first positioning frame 22 may be composed of at least four first frames 220 respectively corresponding to the corresponding corners of the mask M.

Furthermore, as shown in FIG. 2A and FIG. 2B, when the mask M previously positioned in the first positioning frame 22 is sucked by the suction head 21, the mask M can be driven by the suction head 21 to be placed on the substrate S. In this case, the mask M can be placed on the substrate S through the at least two fixed positioning members 10 (as shown in FIG. 2B). For example, in other words, since "the above at least two mask positioning holes M13" (the position and function of which are designed may be the same as the second mask positioning hole M13 of the first embodiment) respectively correspond to the above at least two The relationship of the fixed positioning member 10", so that the at least two mask positioning holes M13' can be accurately fixed by the at least two at least two moments when the mask M is driven by the suction head 21 to be placed on the substrate S. The locating member 10 is passed through so that the mask M can naturally and naturally follow without touching the illuminating diode dies of the illuminating unit L and the wires thereof (refer to FIG. 1H). The ground is passed through the at least two fixed positioning members 10 to be positioned on the substrate S.

In addition, as shown in FIG. 2B and FIG. 2C, after the mask M is placed and positioned on the substrate S (as shown in FIG. 2B), the carrier 1 can be first removed from the first working machine 2, and then The carrier 1 is positioned on a second working machine 3 (shown in FIG. 2C) at a predetermined distance from the first working machine 2 for spraying the subsequent fluorescent colloid (refer to FIG. 1H). For example, the second working machine 3 includes an electromagnetic force generating module 30 for generating magnetic attraction and an electromagnetic force control module 31 for turning on or off the electromagnetic force generating module 30. Thereby, when the carrier 1 is positioned on the second working machine 3, the magnetic attraction force generated by the module 30 can be generated by the electromagnetic force so that the mask M is closely adsorbed on the substrate S. In other words, the magnetic attraction force generated by the electromagnetic force control module 31 after the electromagnetic force generating module 30 is turned on, the mask M can be completely adhered to the substrate S so that the mask M and the substrate S are less likely to be generated. The micro-gap penetrated by the fluorescent colloid sprayed by the subsequent process, thereby preventing the second working machine 3 from being contaminated by the fluorescent colloid.

In addition, referring to FIG. 2C and FIG. 2D, the carrier 1 of the completed fluorescent colloid spraying process is first removed from the second working machine 3, and then the carrier 1 is again positioned on the first working machine 2. The mask M is then sucked from the substrate S through the suction head 21.

2D and 2E, after the mask M is sucked from the substrate S by the pick-up head 21, the sucked mask M is first placed at at least four corresponding corners respectively corresponding to the mask M. In the second positioning frame 23 composed of the second frame 230, the substrate S on which the fluorescent colloid spraying process has been completed can be smoothly removed from the carrier 1.

In summary, the second embodiment of the present invention mainly provides a positioning system, which can be used to respectively locate at least one substrate S for carrying a plurality of light-emitting units L (shown in FIG. 2A) and at least one corresponding to the substrate. The mask M of S (shown in FIG. 2B), wherein the positioning system comprises: a first working machine 2, a second working machine 3, and a carrier 1. The first working machine 2 includes at least one suction head 21 for sucking the mask M. The second working machine 3 is at a predetermined distance from the first working machine 2. The carrier 1 is selectively positionable on one of the first working machine 2 and the second working machine 3, wherein the carrier 1 has at least two fixed positioning members S10 through which the substrate S can pass Two fixed positioning members S10 are positioned on the carrier 1, and the mask M is permeable to the substrate S through the at least two fixed positioning members S10.
