Description

Technical Field

[0001] The present invention relates to a holding mechanism, and more particularly to a holding mechanism and a method for holding an optical fiber array element. Background Art

[0002] In the semiconductor industry, silicon photonics (SiPh) technology has become a key focus for the production of chips with higher transmission efficiency and lower power consumption. Whether it's pluggable transceiver optics (PTO), on-board optics (OBO), co-packaged optics (CPO), or optical I / O, all require coupling a fiber array unit (FAU) to an integrated circuit (IC).

[0003] When performing the operation of coupling the optical fiber array element to the integrated circuit element, it is often necessary to hold the optical fiber array element with a holding mechanism. Specifically, the middle portion of the optical fiber array element is held by a single clamp or a single suction nozzle on the holding mechanism. Since the current semiconductor process has evolved to 2.5D or 3D packaging, the integrated circuit elements and optical fiber array elements have also changed in structure in line with the evolution of the process. For example: an integrated circuit element is provided with a photonic integrated circuit (PIC); an optical fiber array element is provided with an optical coupling portion, a socket portion, and an optical fiber portion connected between the optical coupling portion and the socket portion. The photonic integrated circuit of the integrated circuit element is coupled to the optical coupling portion of the optical fiber array element, and optically communicates with the outside world through the optical fiber portion and the socket portion of the optical fiber array element.

[0004] However, the method of holding the optical fiber array element with only a single clamp or a single nozzle is not stable, and the optical fiber array element may fall from the holding mechanism. In addition, for the optical fiber array element comprising the optical coupling portion, the socket portion, and the optical fiber portion, the optical fiber portion located in the middle of the optical fiber array element is not suitable for being held by a clamp or a nozzle. Therefore, how to hold the optical fiber array element comprising the optical coupling portion, the socket portion, and the optical fiber portion has become a research topic in the current industry. Summary of the Invention

[0005] Therefore, an object of the present invention is to provide a component holding method that overcomes at least one of the disadvantages of the prior art.

[0006] Therefore, the component holding method of the present invention is suitable for holding an optical fiber array component, which is provided with an optical coupler portion, a socket portion, and an optical fiber portion connected between the optical coupler portion and the socket portion. The component holding method includes: (a) providing a holding member, which is provided with a first holding portion and a second holding portion; and (b) causing the first holding portion to hold the optical coupler portion of the optical fiber array component, and causing the second holding portion to hold the socket portion of the optical fiber array component.

[0007] Therefore, another object of the present invention is to provide a retaining mechanism that overcomes at least one of the disadvantages of the prior art.

[0008] Therefore, the holding mechanism of the present invention is suitable for holding an optical fiber array element, which has an optical coupler, a socket, and an optical fiber connected between the optical coupler and the socket. The holding mechanism has a holding assembly.

[0009] The holding assembly is provided with a holding member, which includes a first holding portion and a second holding portion spaced apart from the first holding portion, wherein the first holding portion is adapted to hold the optical coupler portion of the optical fiber array element, and the second holding portion is adapted to hold the socket portion of the optical fiber array element.

[0010] The effect of the present invention is that the optical fiber array element can be firmly held by utilizing the above design. BRIEF DESCRIPTION OF THE DRAWINGS

[0162] Before the present invention is described in detail, it should be noted that similar elements are denoted by the same reference numerals in the following description.

[0163] See also Figure 1 and Figure 5 A first embodiment of the holding mechanism of the present invention is applicable to a process of coupling an optical fiber array element W1 to an integrated circuit element W2.

[0164] See also Figures 2 to 4The optical fiber array element W1 comprises an optical coupler W11, a socket W12, and an optical fiber portion W13 connected between the optical coupler W11 and the socket W12. The optical coupler W11 is made of a light-transmissive material and is provided with a prism W111. The prism W111 is located on a first side surface W112 of the optical coupler W11, away from the socket W12. The socket W12 allows the optical fiber portion W13 to pass through and emerge from a second side surface W121 of the socket W12, away from the optical coupler W11. The socket W12 comprises a first seat W122, which is relatively wide; a second seat W123, which extends from the first seat W122 and is narrower than the first seat W122; and two guide holes W124 extending through the first seat W122 and the second seat W123. The second side surface W121 extends upward from the bottom away from the optical coupling portion W11 and is inclined outward. The optical fiber portion W13 includes a plurality of optical fibers W131 connected to the optical coupling portion W11 and the socket portion W12, and extends in the same direction as the guide hole W124 and is flexible.

[0165] See Figure 1 and Figure 2 The integrated circuit element W2 comprises a carrier W21, a cover W22 disposed on the carrier W21, and at least one photonic integrated circuit W23 disposed on the carrier W21 (in the embodiment of the present invention, multiple photonic integrated circuits W23 are disposed on the carrier W21). The carrier W21 is roughly rectangular, and the photonic integrated circuits W23 can be arranged on one side of the carrier W21. The cover W22 comprises a first cover portion W221, a second cover portion W222 connected to the first cover portion W221 and slightly lower in height than the first cover portion W221, and a hollow section W223. The hollow section W223 is located between the first cover portion W221 and the second cover portion W222, and exposes an area of ​​the carrier W21 between the first cover portion W221 and the second cover portion W222, thereby allowing the photonic integrated circuits W23 on the carrier W21 to be exposed from the cover W22.

[0166] In some embodiments, the hollowed-out area W223 may vary according to the design requirements of the photonic integrated circuit W23. For example, the hollowed-out area W223 is provided at each of the four proximal sides of the corresponding rectangular carrier W21; each photonic integrated circuit W23 is provided with a lens array W231, and the lens array W231 may be composed of a plurality of lenses W2311 (at Figure 2 The cross-sectional diagram shows two) matrices arranged.

[0167] When the optical fiber array element W1 is coupled to the integrated circuit element W2, the optical coupling portion W11 of the optical fiber array element W1 can be attached to the corresponding photonic integrated circuit W23 using glue, and the socket portion W12 can be attached to the second cover portion W222 of the cover W22 using glue. The optical fiber array element W1 uses the prism W111 to correspond to the multiple lenses W2311 of the lens array W231, so that an optical signal W3 can be transmitted between the prism W111 of the optical fiber array element W1 and the lens array W231 of the photonic integrated circuit W23. In this example. The optical signal W3 can be measured by a measuring unit (such as Figure 6 901) is supplied to the optical fiber array element W1. The optical signal W3 can be transmitted from the optical fiber array element W1 to the integrated circuit element W2, and then transmitted back to the optical fiber array element W1 by the integrated circuit element W2. The measuring unit can measure an intensity value of the optical signal W3 transmitted back to the optical fiber array element W1. The optical coupling portion W11 and the photonic integrated circuit W23 can be adhered and fixed by a first adhesive material F1, and the socket portion W12 and the cover W22 can be adhered and fixed by a second adhesive material F2. In the embodiment of the present invention, the first adhesive material F1 is a UV curing adhesive, and the second adhesive material F2 is a heat curing adhesive.

[0168] In other embodiments of the present invention, the cover W22 may omit the second cover portion W222 and only have the first cover portion W221 , and the socket portion W12 is abutted against the carrier W21 .

[0169] See Figures 5 to 7 A first embodiment of a retaining mechanism A according to the present invention can be illustrated as an example of a retaining mechanism A suitable for retaining an optical fiber array element W1. In this embodiment, a first direction d1 is defined as a front-to-back transverse direction, a second direction d2 is defined as a left-to-right transverse direction perpendicular to the first direction d1, and a third direction d3 is defined as a top-to-bottom longitudinal direction perpendicular to the first direction d1 and the second direction d2.

[0170] The holding mechanism A is provided with a component coupling device (such as Figure 19 A bracket 1 (No. 902), a holding component 2 provided on the bracket 1 and capable of holding the optical fiber array element W1, a docking component 3 provided on the bracket 1 and capable of connecting to the measuring unit 901, a driving component 4 provided on the bracket 1 and capable of driving the docking component 3 to move back and forth along the first direction d1, and a curing component 5 provided on the bracket 1 and capable of curing the adhesive.

[0171] See Figures 6 to 8The bracket 1 is provided with an air passage 12 which is connected to an air nozzle 11. The air nozzle 11 is connected to a negative pressure source (not shown). In detail, the bracket 1 is provided with a generally upright rectangular plate body which can be mounted on a component coupling device (such as Figure 19 The air duct 12 includes a bracket connecting portion 13 (numbered 902), a main body 14 connected to the bottom side of the bracket connecting portion 13 and extending forward and backward in the first direction d1, a first mounting portion 15 extending downward from the front side of the main body 14, a second mounting portion 16 extending downward from the rear side of the main body 14, and the air duct 12 defined between the main body 14 and the first mounting portion 15. The air duct 12 includes a first ventilation section 121 extending upward from the bottom surface of the first mounting portion 15 to the front side of the main body 14, and a second ventilation section 122 directly connected to the first ventilation section 121 and extending from the front side of the main body 14 to the rear side of the main body 14. The air nozzle 11 can be inserted into the rear side of the second ventilation section 122 of the air duct 12 and can be connected to the negative pressure source.

[0172] See Figure 5 and Figure 19 Because the holding assembly 2, the docking assembly 3, and the driving assembly 4 are all mounted on the bracket 1, and because the bracket 1 is mounted on a component coupling device 902 and can be driven by the component coupling device 902 to move in conjunction with the holding assembly 2 and the docking assembly 3, the bracket 1 can be driven to move synchronously with the holding assembly 2 and the docking assembly 3. The term "movement" herein includes linear displacement, rotation, swinging, and / or rotation.

[0173] See also Figures 6 to 8 、 Figure 10 The retaining assembly 2 includes a retaining member 21 and a limiting component 22 provided on the retaining member 21. The retaining member 21 includes a retaining main body 211 that is generally T-shaped in front view and connected to the bottom side of the first mounting portion 15 of the bracket 1, a first retaining portion 212 extending downward from the front side of the retaining main body 211, a second retaining portion 213 extending downward from the rear side of the retaining main body 211, and a limiting portion 214 provided on the second retaining portion 213.

[0174] See Figure 7 、 Figure 9 、 Figure 10The first retaining portion 212 is provided with a first retaining surface 2121 located on the bottom side and facing downward, and a first negative pressure hole 2122 formed on the first retaining surface 2121. The first negative pressure hole 2122 extends upward from the first retaining surface 2121 along the third direction d3. The second retaining portion 213 is located at a distance from the rear side of the first retaining portion 212 in the first direction d1, and is provided with a second retaining surface 2131 located on the bottom side and facing downward, and a second negative pressure hole 2132 formed on the second retaining surface 2131. The second negative pressure hole 2132 extends upward from the second retaining surface 2131 along the third direction d3. The retaining body 211 is provided with a connecting passage 2111. The connecting passage 2111 extends up and down and directly connects between the bottom side of the first ventilation section 121 of the air duct 12 and the top sides of the first negative pressure hole 2122 and the top sides of the second negative pressure hole 2132.

[0175] Therefore, the first negative pressure hole 2122 and the second negative pressure hole 2132 are both connected to the air nozzle 11, and can be connected to the negative pressure source via the air nozzle 11. When the negative pressure source is activated, on the one hand, air can be pumped into the first negative pressure hole 2122 via the air channel 12 and the connecting channel 2111, so that the optical coupling portion W11 of the optical fiber array element W1 can be pumped by the negative pressure source via the first negative pressure hole 2122 and the air nozzle 11, and can be held on the first holding surface 2121 by adsorption. On the other hand, the negative pressure source can pump air into the second negative pressure hole 2132 via the air channel 12 and the connecting channel 2111, so that the socket portion W12 of the optical fiber array element W1 can be pumped by the second negative pressure hole 2132 and the air nozzle 11, and can be held on the second holding surface 2131 by adsorption.

[0176] Thus, the first retaining portion 212 can retain the optical coupler portion W11 of the optical fiber array element W1, and the second retaining portion 213 can retain the socket portion W12 of the optical fiber array element W1. Thus, the retaining member 21 simultaneously retains both ends of the optical fiber array element W1, allowing the optical fiber array element W1 to be securely held on the retaining assembly 2, thereby reducing the risk of the optical fiber array element W1 falling from the retaining mechanism A.

[0177] See Figure 3 、 Figure 10 and Figure 11The limiting portion 214 is located on a side of the second retaining portion 213 away from the first retaining portion 212 and is provided with two limiting sections 2141. The limiting sections 2141 protrude downward from the left and right sides of the second retaining surface 2131 and are strip-shaped, extending forward and backward along the first direction d1. The length of each limiting section 2141 in the first direction d1 is less than the length of the second retaining surface 2131 in the first direction d1. The limiting portion 214 also has a clearance area 2142. The clearance area 2142 is a space formed between the limiting sections 2141, and allows the second seat portion W123 of the socket portion W12 to pass through it along the first direction d1, so that when the optical fiber array element W1 is subjected to backward pushing or pulling force, the first seat portion W122 with a wider width of the socket portion W12 can be locked against the front edge of the limiting section 2141, thereby limiting the optical fiber array element W1 from moving backward in the first direction d1.

[0178] See Figure 9 、 Figure 16 、 Figure 17 The limiting component 22 is provided with a limiting pivot 221 rotatably provided in the retaining main body 211 of the retaining member 21 in the second direction d2, two limiting members 222 respectively connected to the left and right ends of the limiting pivot 221, and two elastic members 223. The limiting members 222 are respectively located on the left and right sides of the retaining member 21 in the second direction d2. Each of the limiting members 222 is provided with two opposite ends spaced apart in the third direction d3, and a fulcrum 2223 located between the two ends. The two ends are respectively a force-bearing end 2221 located on the top side, and a limiting end 2222 located on the bottom side. The limiting ends 2222 are spaced apart in front of the limiting portion 214 of the retaining member 21. The limiting pivot 221 is disposed through the retaining member 21 and connected to the fulcrum 2223 of the limiting member 222, so that the limiting member 222 is pivoted to the retaining member 21 at the fulcrum 2223 between the limiting end 2222 and the force-bearing end 2221. Thus, the limiting member 222 can swing relative to the retaining member 21 with the limiting pivot 221 as the center. When the force-bearing end 2221 of the limiting member 222 is forced to rotate forward, the limiting end 2222 can swing backward. Each elastic member 223 is sleeved on the limiting pivot 221 and disposed between the retaining member 21 and its respective limiting member 222. In this embodiment, each elastic member 223 is a torsion spring, which provides an elastic restoring force that enables the corresponding force-bearing end 2221 of the limiting member 222 to rotate forward under a pushing force.

[0179] In some embodiments, the number of the limiting member 222 of the limiting component 22 may be one, so that the number of the limiting end 2222, the force-bearing end 2221 and the fulcrum 2223 of the limiting member 222 is also one respectively.

[0180] Since the limiting member 222 can move the limiting end 2222 backward toward the limiting portion 214 when driven by force, and the limiting end 2222 is located in front of the limiting portion 214 at intervals, when the first seat W122 of the socket portion W12 of the optical fiber array element W1 is located between the limiting end 2222 and the limiting portion 214, the limiting end 2222 and the limiting portion 214 will jointly limit the first seat W122 of the socket portion W12 to limit the movement of the optical fiber array element W1 in the first direction d1.

[0181] See Figure 8 、 Figure 16 , the driving assembly 4 is provided with a driving member 41 in an inverted "U"-shaped area connected to the bottom side of the second mounting portion 16 of the bracket 1, and a moving member 42 that can be driven by the driving member 41 to move back and forth relative to the driving member 41 in the first direction d1. The driving member 41 can be, but is not limited to, a motor, a pneumatic cylinder or a hydraulic cylinder. In the present embodiment, the driving member 41 includes a driving body 410, and a telescopic rod 411 connected to the driving body 410 and capable of extending back and forth relative to the driving body 410. When the driving body 410 is a motor, the telescopic rod 411 can be a motor-driven screw. The moving member 42 is roughly "L"-shaped when viewed from above, is connected to the front end of the telescopic rod 411, and extends backward from one side of the driving member 41 as a whole. Thereby, the moving member 42 can be driven by the driving member 41 to move back and forth relative to the driving member 41 in the first direction d1. The driving assembly 4 can be an electric cylinder or a slide cylinder, and the moving member 42 can only move linearly back and forth in the first direction d1.

[0182] See Figure 8 、 Figures 12-15 The docking assembly 3 includes a mounting base 31 connected to the moving member 42, a moving base 32 connected to the bottom side of the mounting base 31 and movable relative to the mounting base 31, and a fixed base 32 fixed to the bottom side of the moving base 32 and capable of connecting with a measuring unit (such as Figure 6 A pair of docking pieces 33 connected with component number 901).

[0183] The mounting base 31 is provided with a mounting body 311 fixedly mounted on the front side of the moving member 42, a push member 312 mounted on the top side of the mounting body 311, and a support member 313 mounted on the bottom side of the mounting body 311. The mounting body 311 is formed with a mounting channel 3111 extending vertically. The push member 312 is provided with two push members 3121, each of which protrudes forward from the front surface of the mounting body 311 and is spaced apart in the second direction d2. Figure 16 Thus, when the mounting base 31 is driven forward by the moving member 42 of the driving assembly 4, the abutting member 312 can abut the force-bearing end 2221 of the limiting member 222, causing the limiting member 222 to deflect forward, and the limiting end 2222 to deflect backward synchronously and move toward the limiting portion 214. In this embodiment, each of the abutting members 3121 can be a spring positioning column.

[0184] See Figure 12 、 Figure 16 The abutment member 313 comprises two abutment members 3131, each inserted and inserted through the bottom side of the mounting body 311. The abutment members 3131 are spaced apart in the second direction d2, and each abutment member 3131 protrudes from the front and rear surfaces of the mounting body 311. In this embodiment, each abutment member 3131 is a spring-loaded positioning column.

[0185] See Figure 12 、 Figures 14 to 16 The movable base 32 comprises a first base 321 rotatably and vertically movably connected to the mounting base 31, a first connecting unit 322, a second base 323 pivotally mounted on the first base 321, and a second connecting unit 324. The first base 321 is disposed on the bottom side of the mounting body 311 and comprises a mounting slot 3211 located on the top side and opening upward, a rearwardly facing abutting surface 3213 located on the rear side, and two pivoting slots 3212 spaced apart and facing each other. The first connecting unit 322 comprises a first shaft 3221 that is vertically movably inserted through the mounting channel 3111 and has its bottom end located in the mounting slot 3211, a bushing 3222 located above the top side of the mounting body 311 and fixedly mounted to the top end of the first shaft 3221, and an elastic member 3223 that sleeves on the first shaft 3221. The bottom end of the first shaft 3221 is fixedly mounted on the first base 321. The elastic member 3223 can be a compression spring and elastically presses between the mounting body 311 and the first base 321.

[0186] The second base 323 is disposed on the bottom side of the first base 321 and is formed with a mounting hole 3231 extending forward and backward. The second connecting unit 324 is provided with two second shafts 3241 spaced apart from each other. The second shafts 3241 are transversely inserted into the left and right sides of the second base 323 in the second direction d2 and are rotatably connected to the pivot slots 3212 of the first base 321.

[0187] See Figure 7 、 Figure 12 、 Figures 14-15 The docking member 33 is disposed in the mounting hole 3231 of the second base 323 and is linked to the second base 323 and exposed from the front side of the second base 323. The docking member 33 has a docking surface 331 facing the retaining member 21, an optical passage portion 332, a guide component 333 that can selectively insert the optical fiber array element W1, and an optical transmission portion 334. The optical passage portion 332 and the guide component 333 are disposed on the docking surface 331. The guide component 333 has two guide pins 3331 that protrude forward from the left and right sides of the docking surface 331 and are disposed on both sides of the optical passage portion 332. The guide pins 3331 can be inserted into the guide hole W124 of the optical fiber array element W1. The optical passage portion 332 is located between the guide pins 3331. The optical transmission portion 334 is connected between the optical passage portion 332 and the measurement unit 901. Please read more Figure 3 The docking surface 331 of the docking member 33 is parallel to the second side surface W121 of the optical fiber array element W1. Therefore, when the docking member 33 is docked with the optical fiber array element W1, the guide pin 3331 is inserted into the guide hole W124, and the docking surface 331 is abutted against the second side surface W121, so that the optical through portion 332 corresponds to the optical fiber portion exposed in the socket portion W12, so that the optical signal from the measuring unit 901 can be transmitted to the optical fiber array element W1.

[0188] See Figure 12 、 Figures 14-16 , thereby, the abutting member 313 can abut against the left and right sides of the abutting surface 3213 of the first base 321 of the movable base 32. The first base 321 can link the second base 323 and the docking member 33 to move up and down relative to the mounting base 31, and can link the second base 323 to swing relative to the mounting base 31 about a longitudinal axis of the first shaft 3221 as the rotation center. The second base 323 can link with the docking member 33 to swing relative to the first base 321 about a transverse axis of the second shaft 3241 as the rotation center. Therefore, the movable base 32 and the docking member 33 can move vertically along a longitudinal axis relative to the mounting base 31, and can swing relative to the mounting base 31 of the docking assembly 3 about a longitudinal axis of the first shaft 3221 as the rotation center.

[0189] Since the docking component 3 is arranged on the movable member 42 and is fixedly connected to the movable member 42, and since the movable member 42 of the driving component 4 can move back and forth in the first direction d1, the docking component 3 can be driven by the driving component 4 and move back and forth in the first direction d1 relative to the retaining member 21, so that the docking member 33 can selectively dock with the optical fiber array element W1 (when the docking member 33 moves forward) or not dock (when the docking member 33 moves backward).

[0190] See Figure 5 、 Figure 6 、 Figure 18 , the curing assembly 5 is provided with two first curing components 501 and one second curing component 502. The first curing components 501 are spaced apart from each other in the second direction d2 and are respectively arranged on both sides of the retaining member 21. Each of the first curing components 501 can irradiate ultraviolet light 51 in a direction of the first retaining portion 212 of the retaining member 21. The second curing component can irradiate laser 52 in a direction of the second retaining portion 213 of the retaining member 21, or blow hot air flow. In this example, each of the first curing components 501 may include an ultraviolet light source, and the second curing component 502 may include a laser source, and / or a hot air generator or a hot air gun.

[0191] See also Figure 5 、 Figure 19 The holding mechanism A can be used on a component coupling device 902. The component coupling device 902 includes: a machine platform T, a first driving mechanism B provided on the machine platform T, a second driving mechanism C provided on the first driving mechanism B and capable of being driven by the first driving mechanism B to perform multi-axial linear movement, and an inspection mechanism D provided on the first driving mechanism B. The inspection mechanism D can be driven by the first driving mechanism B to perform multi-axial linear movement and can inspect the integrated circuit component (such as Figure 1 No. W2) for inspection.

[0192] The holding mechanism A is mounted on the second drive mechanism C and is driven by the second drive mechanism C to perform multi-axial rotational movement. The holding mechanism A can hold the optical fiber array element W1 and, driven by the first drive mechanism B and the second drive mechanism C, drive the optical fiber array element W1 to perform multi-axial linear movement or rotational movement.

[0193] Specifically, the first driving mechanism B includes a first linear motion component B1 disposed on the machine T, a second linear motion component B2 disposed on the first linear motion component B1 , and a third linear motion component B3 disposed on the second linear motion component B2 .

[0194] The first linear motion assembly B1 comprises two first rails B11 spaced apart from each other and mounted on the machine T, and two first slides B12 mounted on each of the first rails B11. The first rails B11 extend along a first direction d1, and the first slides B12 are movable along the first direction d1 on the first rails B11. The second linear motion assembly B2 comprises a second rail B21 straddling the two first slides B12, and a second slide B22 mounted on the second rail B21. The second rail B21 extends along a second direction d2, and the second slide B22 is movable along the second direction d2 on the second rail B21. The third direct-acting assembly B3 is provided with a third rail base B31 provided on the second slide B22 and a third slide B32 provided on the third rail base B31; the third rail base B31 extends along the third direction d3, and the third slide B32 can move on the third rail base B31 along the third direction d3.

[0195] Thereby, the first driving mechanism B can drive the second driving mechanism C to link the holding mechanism A to drive the optical fiber array element W1 to perform linear movement with three degrees of freedom in the first direction d1, the second direction d2, and the third direction d3.

[0196] In the embodiment of the present invention, the first rail base B11 and the second rail base B21 use linear motors to drive the first slide B12 and the second slide B22, but this is not limited to this. For example, a combination of a rotary motor and a screw can also be used. In the embodiment of the present invention, the third rail base B31 uses a combination of a rotary motor and a screw to drive the third slide B32, but this is not limited to this. For example, a linear motor can also be used.

[0197] The second driving mechanism C can drive the holding mechanism A to drive the optical fiber array element W1 to rotate and move. Since the driving method of the second driving mechanism C is not the technical focus of the present invention, it will not be described in detail here.

[0198] The machine T is further provided with a first platform S1, a second platform S2 spaced apart from the first platform S1 in the second direction d2, a gluing station S3 located on one side of the first platform S1, and an inspection station S4 located between the first platform S1 and the second platform S2.

[0199] See Figure 20 The following describes an embodiment of a component holding method using a first embodiment of the holding mechanism A. This embodiment of the component holding method is suitable for holding the optical fiber array component (such as Figure 1 The process is shown as step W1), and includes a step 91, a step 92, and a step 93.

[0200] In step 91 , the retaining member is provided, wherein the retaining member is provided with the first retaining portion and the second retaining portion.

[0201] In step 92, the first holding portion holds the optical coupler portion of the optical fiber array element, and the second holding portion holds the receptacle portion of the optical fiber array element.

[0202] See Figure 7 、 Figure 16 、 Figure 19 First, the optical fiber array element W1 is placed on the first stage S1, and the integrated circuit element W2 is placed on the second stage S2. Next, the retaining mechanism A is driven to move above the first stage S1. The retaining mechanism A is then driven to move downward until the retaining assembly 2 contacts the optical fiber array element W1 on the first stage S1. At the same time, the negative pressure source activates negative pressure, causing the first retaining portion 212 of the retaining member 21 to absorb the optical coupler portion W11 of the optical fiber array element W1 by suction, and the second retaining portion 213 also absorbs the socket portion W12 of the optical fiber array element W1 by suction.

[0203] See Figure 20 , proceed to step 93, providing a limiting member movable relative to the retaining member, the limiting member being drivable to push against the socket portion of the optical fiber array element to limit movement of the socket portion. Step 93 is described in detail below.

[0204] See Figure 16 and Figure 17 First, the telescopic rod 411 of the driving member 41 of the driving assembly 4 is extended forward, so that the moving member 42 is linked with the docking assembly 3 and moves forward in the first direction d1, until the pushing member 312 of the docking assembly 3 pushes the force-bearing end 2221 of the limiting member 222 of the limiting member 22 forward to deflect forward, and then the limiting end 2222 of the limiting member 222 is deflected backward with the fulcrum 2223 as the center, which can push against the first seat W122 of the socket part W12 of the optical fiber array element W1, on the one hand, limiting the forward movement of the socket part W12 in the first direction d1, and on the other hand, pushing the first seat W122 of the socket part W12 against the limiting part 214 of the retaining assembly 2, so that the limiting part 214 of the retaining assembly 2 can also limit the backward movement of the socket part W12 in the first direction d1. Specifically, the movement of the socket portion W12 is restricted because the first seat portion W122 of the socket portion W12 is clamped between the limiting end 2222 of the limiting member 222 and the limiting portion 214 of the retaining assembly 2 .

[0205] Further reference Figure 3 、 Figure 14On the other hand, in the process of the docking assembly 3 being driven forward, the docking member 33 is also driven forward until the guide pin 3331 of the guide component of the docking member 33 is inserted into the guide hole W124 of the socket part W12 of the optical fiber array element W1, and the docking surface 331 of the docking member 33 is abutted against the second side surface W121 of the socket part W12, so that the docking member 33 is docked with the optical fiber array element W1, and since the docking member 33 is inserted into the socket part W12 forward and the limiting member 222 is pushed backward against the socket part W12, the direction in which the docking member 33 is inserted into the socket part W12 and the direction in which the limiting member 222 is pushed against the socket part W12 are opposite to each other.

[0206] In this embodiment, by utilizing the design of the pushing component 312, when the docking component 33 moves relative to the retaining component 21, the docking component 33 pushes the force-bearing end 2221 of the limiting component 222 and links with the limiting component 22, thereby causing the limiting component 222 to move relative to the retaining component 21.

[0207] During docking of the docking member 33 with the optical fiber array element W1, the design of the first connecting unit 322 allows the movable seat 32 to rotate relative to the mounting seat 31 along the longitudinal axis and to slightly move up and down relative to the mounting seat 31. The design of the second connecting unit 324 allows the second seat body 323 of the movable seat 32 to rotate relative to the first seat body 321 along the transverse axis. This allows the guide pin 3331 of the docking member 33 to accurately insert into the guide hole W124 even if the extension direction of the guide hole W124 of the socket portion W12 and the extension direction of the guide pin 3331 of the docking member 33 do not precisely align along the same imaginary straight line extending along the first direction d1.

[0208] See Figure 1 、 Figure 20 After completing steps 91 to 93 of the above-mentioned component holding method, a bonding step and a curing step may be performed to couple the optical fiber array component W1 to the integrated circuit component W2.

[0209] See Figure 1 、 Figure 2 and Figure 19In the bonding step, the holding mechanism A can be driven by at least the first driving mechanism B and moved as a whole to the glue coating station S3 of the first carrier S1 to apply glue. The glue coating station S3 can apply the first glue F1 and the second glue F2 to the lower surfaces of the optical coupler W11 and the socket W12, respectively. After the glue is applied to the optical fiber array element W1, the holding mechanism A is driven by at least the first driving mechanism B and moved above the second carrier S2. Subsequently, the holding mechanism A is driven by the first driving mechanism B and / or the second driving mechanism C to move downward, so that the lower surface of the optical coupler W11 and the lower surface of the socket W12 are adhered to the photonic integrated circuit W23 and the second cover W222 of the cover W22 via the first glue F1 and the second glue F2, respectively. Thereby, the optical signal W3 from the measuring unit 901 can be transmitted between the optical fiber array component W1 and the integrated circuit component W2 via the prism W111 and the lens array W231 .

[0210] Before the optical fiber array element W1 is bonded to the integrated circuit element W2, the position of the photonic integrated circuit W23 and / or the lens array W231 and the flatness of the upper surface of the photonic integrated circuit W23 can be obtained by the inspection mechanism D, for example, by video recording, multi-point ranging, etc. The position of the optical coupler W11 and / or the prism W111 and the flatness of the lower surface of the optical coupler W11 can be obtained by the inspection station S4 between the first stage S1 and the second stage S2, for example, by video recording, multi-point ranging, etc. Therefore, when the holding mechanism A couples the optical fiber array element W1 to the integrated circuit element W2, the first driving mechanism B can drive the second driving mechanism C to link the holding mechanism A to drive the optical fiber array element W1 to perform multi-axial linear movement, and the second driving mechanism C can drive the holding mechanism A to drive the optical fiber array element W1 to perform multi-axial rotational movement, so that the posture (orientation, flatness) of the optical fiber array element W1 can correspond to the posture (orientation, flatness) of the photonic integrated circuit W23.

[0211] See Figure 1 、 Figure 2 、 Figure 5 、 Figure 18 After the optical fiber array element W1 is bonded to the integrated circuit element W2, a curing step may be performed to complete the coupling between the optical fiber array element W1 and the integrated circuit element W2. The curing step is described below.

[0212] The curing step utilizes the first curing component 501 and the second curing component 502 of the curing assembly 5 to cure the first adhesive F1 and the second adhesive F2 using ultraviolet light and laser light, respectively. Because the optical coupler W11 is made of a light-transmitting material, the ultraviolet light 51 can penetrate the optical coupler W11 and cure the first adhesive F1 between the optical coupler W11 and the photonic integrated circuit W23. Because the laser light 52 can generate heat energy, it can heat and cure the second adhesive F2 between the socket W12 and the second cover W222 of the cover W22. Figure 2 、 Figure 3 and Figure 16 After the first adhesive F1 and the second adhesive F2 are cured, the driving assembly 4 drives the docking assembly 3 away from the optical fiber array element W1, so that the guide pin 3331 of the guide component 333 is pulled out of the guide hole W124 of the socket portion W12 of the optical fiber array element W1, thereby releasing the docking with the optical fiber array element W1.

[0213] During the process of undocking the docking assembly 3 from the optical fiber array element W1, the docking assembly 3 is driven backward by the drive assembly 4. The receptacle W12 may be pulled backward and away from the optical coupler W11 by the frictional force of the guide pin 3331 of the docking assembly 3 withdrawing from the guide hole W124. At this time, the design of the retaining portion 214 of the retaining member 21 can limit the rearward movement of the receptacle W12, allowing the guide pin 3331 to be removed from the guide hole W124.

[0214] After the docking assembly 3 is released from the docking with the optical fiber array element W1, the negative pressure source stops generating negative pressure, so that the retaining assembly 2 no longer adsorbs the optical fiber array element W1 and can be moved away from the optical fiber array element W1, completing the process of coupling the optical fiber array element W1 to the integrated circuit element W2.

[0215] See Figure 1 、 Figure 6 、 Figure 19 The first driving mechanism B of the component coupling device 902 can drive the second driving mechanism C to link the holding mechanism A to repeat the above actions in sequence to couple a preset number of the optical fiber array components W1 to the integrated circuit component W2.

[0216] In the above-described component holding method, the docking member 33 connected to the measurement unit 901 can move relative to the holding member 21, thereby selectively docking or undocking with the optical fiber array component W1. Thus, the holding mechanism A not only holds the optical fiber array component W1 but also facilitates measurement of the optical fiber array component W1.

[0217] In summary, the retaining mechanism A and retaining method of the present invention utilize the spaced-apart first retaining portion 212 and the spaced-apart second retaining portion 213 to respectively retain the optical coupler portion W11 and the socket portion W12 of the optical fiber array element W1, thereby simultaneously retaining both ends of the optical fiber array element W1 and thereby securely holding the optical fiber array element W1 on the retaining member 21, thereby reducing the risk of the optical fiber array element W1 falling from the retaining mechanism A. Furthermore, the relative movement between the docking member 33 and the retaining member 21 allows the docking member 33 to selectively dock or undocking with the optical fiber array element W1. The design of the limiting portion 214 prevents the socket portion W12 from moving away from the optical coupler portion W11 when the docking member 33 is removed from the optical fiber array element W1. The design of the limiting member 22 prevents the socket portion W12 from moving toward the optical coupler portion W11 when the docking member 33 is inserted into the optical fiber array element W1. Therefore, the holding mechanism A and the holding method of the present invention can firmly hold the optical fiber array element W1, and thus can surely achieve the purpose of the present invention.

[0218] See also Figure 21 、 Figure 22 A second embodiment of the retaining mechanism of the present invention can be illustrated using a retaining mechanism A' suitable for retaining the optical fiber array element W1 as shown in the figure. The primary difference between this second embodiment and the first embodiment lies in the differences in the retaining assembly 2 and the docking assembly 3. These differences are described below.

[0219] See also Figure 23 、 Figure 24 、 Figure 25 A retaining assembly 2' of the retaining mechanism A' is provided with a retaining member 21', and the retaining member 21' is provided with a first retaining portion 212' and a second retaining portion 213' spaced apart from the first retaining portion 212' in the first direction d1. The first retaining portion 212' can retain the optical coupler portion W11 of the optical fiber array element W1, and the second retaining portion 213' can retain the socket portion W12 of the optical fiber array element W1. The retaining member 21' is also provided with a first limiting portion 23' and a second limiting portion 24'. The first limiting portion 23' is provided on a side of the second retaining portion 213' close to the first retaining portion 212', and the second limiting portion 24' is provided on a side of the second retaining portion 213' away from the first retaining portion 212'. The first limiting portion 23' is provided with a first clearance area 231' for the optical fiber portion W13 of the optical fiber array element W1 to pass through, and the second limiting portion 24' is provided with a second clearance area 241' for the second seat portion W123 of the socket portion W12 of the optical fiber array element W1 to pass through. Figure 4When the optical fiber array element W1 is adsorbed and held by the retaining assembly 2', the first seat portion W122 of the socket portion W12 with a wider width will be located between the first limiting portion 23' and the second limiting portion 24' and be limited, so that the first limiting portion 23' and the second limiting portion 24' limit the movement of the optical fiber array element W1 on the retaining assembly 2' in the first direction d1.

[0220] See also Figure 23 、 Figures 26-27 The docking assembly 3' of the holding mechanism A' comprises a mounting base 31' connected to the moving member 42, a movable base 32' pivotally mounted on the bottom side of the mounting base 31' and movable relative to the mounting base 31', a fixed base 32' mounted on the bottom side of the movable base 32' and capable of engaging with the measuring unit (such as Figure 22 901) and a connecting piece 33' and an elastic piece 34'. The connecting piece 33' and the connecting piece of the first embodiment (such as Figure 15 33) has a similar structure and is inserted through the movable seat 32'. It can pivot forward and backward along a transverse axis L1 parallel to the second direction d2 relative to the mounting seat 31' when subjected to an external force. One end of the elastic member 34' is attached to the mounting seat 31', and the other end of the elastic member 34' is attached to the movable seat 32'. The elastic member 34' accumulates elastic restoring force during the pivoting of the movable seat 32', allowing the movable seat 32' to drive the docking member 33' back to its original position after pivoting. The elastic member 34' can, for example, comprise a spring.

[0221] See also Figures 26-29 During the docking process between the docking member 33' and the optical fiber array element W1, the movable seat 32' and the docking member 33' will pivot backward and accumulate the elastic restoring force of the elastic member 34'. The socket portion W12 may be pushed by the docking member 33' and move toward the direction approaching the optical coupling portion W11. However, because the first limiting portion 23' is located between the socket portion W12 and the optical coupling portion W11, the first limiting portion 23' can block the first seat portion W122 of the socket portion W12, thereby preventing the socket portion W12 from continuing to move toward the direction approaching the optical coupling portion W11.

[0222] During the process of undocking the docking member 33' from the optical fiber array element W1, the movable seat 32' and the docking member 33' will pivot forward and accumulate the elastic restoring force of the elastic member 34'. The socket portion W12 may be pulled by the docking member 33' and move away from the optical coupling portion W11. However, because the second limiting portion 24' is blocked between the first seat portion W122 of the socket portion W12 and the docking member 33', the socket portion W12 is prevented from being further pulled by the docking member 33'. After the docking member 33' is undocking from the optical fiber array element W1, the movable seat 32' is driven by the elastic restoring force of the elastic member 34' to return the docking member 33' to its original position.

[0223] See Figure 22 and Figure 23 In the embodiment of the present invention, the holding mechanism A' can also firmly hold the optical fiber array element W1.

[0224] The above descriptions are merely embodiments of the present invention and should not be used to limit the scope of implementation of the present invention.
