Description

Technical Field

[0001] This application relates to the field of optical communication equipment technology, and in particular to a shaping device, an automatic insertion device, and an automatic insertion method. Background Technology

[0002] An optical network terminal (ONU), commonly known as an optical modem, is a key node device in a passive optical network (PON) and is widely used in FTTH (Fiber To The Home) and FTTR (Fiber To The Room) scenarios.

[0003] In the fabrication of optical network terminals, a Bi-Directional Optical Subassembly (BOSA) needs to be mounted onto a circuit board. However, the BOSA consists of multiple transmitting pins and multiple receiving pins; the transmitting pins are located at the ends, and the receiving pins are located on the sides, extending in mutually perpendicular directions. Therefore, during the mounting process of the BOSA onto the circuit board, the transmitting pins need to be bent to the side where the receiving pins are located.

[0004] However, due to the large number of multiple transmitting pins, all of which are flexible pins with low rigidity and slender shape, they are prone to bending, clustering, and crossing, making it impossible to extend them in the designed direction. This makes it difficult to automate the insertion of the optical transmitting / receiving components into the circuit board using automated equipment. In related technologies, the insertion of optical transmitting / receiving components into the circuit board typically relies on manual operation, resulting in low insertion efficiency. Summary of the Invention

[0005] This application provides a shaping device, an automatic insertion equipment, and an automatic insertion method to improve the problem that the insertion of optical transmitting and receiving components and circuit boards relies on manual operation and has low insertion efficiency.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] In a first aspect, a shaping device is provided for shaping an optical transmitting and receiving assembly. The optical transmitting and receiving assembly includes multiple transmitting pins and multiple receiving pins, with the multiple transmitting pins disposed on a transmitting base and the multiple receiving pins disposed on a receiving base; the transmitting base is located at one end of the optical transmitting and receiving assembly along its length, and the receiving base is located on the side of the optical transmitting and receiving assembly.

[0008] The shaping device includes a first motion platform, a straightening assembly, and a bending assembly. The straightening assembly and the bending assembly are both mounted on the first motion platform, which drives the straightening assembly and the bending assembly to move along a first direction.

[0009] The straightening assembly includes a first comb tooth, a second comb tooth, and a first driving device. The first and second comb teeth extend into the roots of multiple hair end pins under the drive of the first driving device and form a pin straightening hole surrounding each hair end pin. The pin straightening hole straightens the surrounding hair end pins during movement along the first direction.

[0010] The bending assembly includes a bending member and a third driving device. The bending member has multiple through bending holes. The third driving device is used to drive the bending member to rotate around an axis. During the rotation of the bending member around the axis, the bending member has an upright state and a bent state. When the bending member is in the upright state, it moves towards the hair end base in a first direction, and the straightened hair end tubes are respectively inserted into the multiple bending holes. During the rotation of the bending member from the upright state to the bent state, the multiple hair end tubes are bent.

[0011] The shaping device designed above can automatically straighten and bend multiple transmitting pins in the optical transmitting and receiving components, which facilitates the automatic insertion of the optical transmitting and receiving components and circuit boards through automated equipment, thereby improving insertion efficiency and enabling automated assembly lines for optical network terminals.

[0012] In some possible implementations, the first comb member is provided with a first comb groove at its end along the fourth direction, and the second comb member is provided with a second comb groove at its end along the fifth direction; the fourth direction and the fifth direction are two intersecting directions perpendicular to the first direction, and the intersection is located at the root of multiple hairpins; in the intersecting first and second comb members, the first comb groove and the second comb groove form a straightening hole for the hairpins.

[0013] The first driving device is used to drive the first comb tooth to move along the fourth direction toward the root of the multiple hairpins, and to drive the second comb tooth to move along the fifth direction toward the root of the multiple hairpins.

[0014] In the shaping device provided in this application, the straightening holes of the tube pins are formed by the intersecting first and second comb grooves, which has the advantages of simple structure and easy implementation.

[0015] In some possible implementations, the combing assembly further includes a first mounting structure and a second driving device, wherein the first comb teeth, the second comb teeth, and the first driving device are all mounted on the first mounting structure; the second driving device is connected to the first mounting structure and is used to drive the first mounting structure to rotate about an axis.

[0016] As the first mounting structure rotates around its axis, it causes the fourth and fifth directions to rotate around their intersection.

[0017] This design allows for changes in the insertion angles of the first and second comb grooves, creating straightening holes with different pin arrangements. This enables the straightening component to be adapted to light emitting and receiving components with different pin arrangements, thus expanding its applicability to both the straightening component and the automatic insertion equipment.

[0018] In some possible implementations, the shaping device further includes a first vision module for obtaining the pose and extension state of multiple hair-end pins; a second driving device drives a third mounting structure to rotate based on the pose and extension state. The first vision module improves the accuracy of the insertion angles of the first and second comb grooves, thereby enhancing straightening efficiency and adapting to light-emitting and receiving components with different hair-end pin arrangement positions.

[0019] In some possible implementations, the first vision module includes a first camera and a second camera. The first camera takes pictures of the side of the light emitting and receiving component along a third direction, and the second camera takes pictures of the emitting base of the light emitting and receiving component. Alternatively, the first vision module includes a first camera and a reflecting device, with the reflecting device facing the emitting base of the light emitting and receiving component. The first camera takes pictures of the side of the light emitting and receiving component along a third direction and also takes pictures of the emitting base through the reflecting device. The third direction is perpendicular to the first direction.

[0020] In the shaping device provided in this application, the first vision module can adopt a dual-camera scheme or a single-camera plus a reflection device scheme. The structural design is flexible and can be adapted to different application scenarios.

[0021] In some possible implementations, the bending assembly is used to bend multiple transmitting pins to the side where multiple receiving pins are located, so that after bending, the multiple transmitting pins are parallel to a third direction; the third direction is perpendicular to the first direction and parallel to the multiple receiving pins. This design facilitates the automatic insertion of optical transmitting and receiving components and circuit boards through automated equipment, thereby improving insertion efficiency and enabling automated assembly lines for optical network terminals.

[0022] In some possible implementations, the bending assembly further includes a second mounting structure and a fourth driving device. The bending element and the third driving device are both mounted on the second mounting structure, and the fourth driving device is connected to the second mounting structure to drive it to move in a third direction. This design allows the bending assembly to detach from the light transmitting and receiving assembly, enabling the light transmitting and receiving assembly to continue rotating.

[0023] In some possible implementations, the bent component includes a bent plate and a bent step. The bent plate includes a first side and a second side disposed opposite each other in the thickness direction. In the upright position of the bent component, the first side is close to the light emitting and receiving component. The bent step is disposed on the first side, and multiple bending holes penetrate the bent step and the bent plate along the thickness direction of the bent plate. This design facilitates the smooth insertion of multiple transmitter pins into multiple bending holes.

[0024] In some possible implementations, the shaping device further includes a first lead-cutting assembly mounted on a first motion platform, the first lead-cutting assembly being used to cut the multiple bent lead ends into different lengths. By cutting the multiple lead ends into different lengths, it is beneficial to achieve the sequential insertion of the multiple lead ends into multiple first lead holes, thereby reducing the insertion difficulty and improving insertion efficiency and accuracy.

[0025] In some possible implementations, the first lead-cutting assembly includes a first lead-cutting blade and a fifth driving device, the fifth driving device being connected to the first lead-cutting blade and used to drive the first lead-cutting blade to move in a direction perpendicular to a third direction toward the multiple bent lead-ends; the third direction is parallel to the multiple bent lead-ends.

[0026] The first cutting tool includes multiple working parts located at different positions in the third direction, one working part being used to cut a single starting pin.

[0027] The shaping device provided in this application has the advantages of simple structure and easy implementation by cutting multiple starting pins into different lengths through multiple working parts located at different positions in the third direction.

[0028] In some possible implementations, the bent component includes a bending plate and a plurality of shear steps, the bending plate including a first side and a second side disposed opposite each other in the thickness direction; in the bent component in an upright state, the first side is close to the light emitting and receiving component.

[0029] Multiple shear steps are set on the second side and correspond one-to-one with multiple action parts; the starting pins of the action parts are cut out through the corresponding shear steps; after bending multiple ending pins, the ends of the shear steps are aligned with the corresponding action parts in the third direction.

[0030] This design allows multiple hairpin ends to be cut to different lengths using the first cutting blade; it also prevents the first cutting blade from bending the hairpin ends during cutting.

[0031] Secondly, an automatic insertion device is provided for inserting an optical transmitting and receiving component into a circuit board; the optical transmitting and receiving component includes multiple transmitting pins and multiple receiving pins, the multiple transmitting pins being disposed on a transmitting base and the multiple receiving pins being disposed on a receiving base; the transmitting base is located at one end of the optical transmitting and receiving component along its length, and the receiving base is located on the side of the optical transmitting and receiving component; the circuit board includes a connection area, in which multiple first pin holes and multiple second pin holes are provided; the multiple receiving pins are inserted into the multiple first pin holes, and the multiple receiving pins are inserted into the multiple second pin holes.

[0032] The automated insertion equipment includes a transfer device, a shaping device as described in any one of the first aspects, and an insertion device. The transfer device includes a carrying tray and a conveying system. The carrying tray carries the light emitting and receiving components and the circuit board. On the carrying tray, the longitudinal direction of the light emitting and receiving components is parallel to a first direction. The conveying system extends along a second direction and drives the carrying tray to move along the second direction. The first and second directions are perpendicular.

[0033] The shaping device is located on one side of the conveying system and is used to shape the light emitting and receiving components on the carrier tray.

[0034] The insertion device and the shaping device are spaced apart in the second direction. The insertion device is located on one side of the conveying system and is used to insert the shaped light emitting and receiving components onto the circuit board.

[0035] The automated insertion equipment designed above can automatically insert optical transmitting and receiving components and circuit boards, thereby improving insertion efficiency and enabling automated assembly lines for optical network terminals.

[0036] In some possible implementations, the automated insertion device further includes a second lead-cutting assembly for shortening multiple terminal leads before the optical transmitter / receiver assembly reaches the insertion device. This design facilitates the automated insertion of the optical transmitter / receiver assembly into the circuit board.

[0037] In some possible implementations, the automated insertion equipment also includes a third lead-cutting assembly for shortening multiple receiver pins after the light-emitting and receiving components have been inserted into the circuit board. This design facilitates post-insertion process steps, such as soldering, of the light-emitting and receiving components.

[0038] In some possible implementations, the carrier tray is provided with a limiting seat, a limiting hole and a cutout, the optical receiving component in the optical transmitting and receiving assembly engages with the limiting seat, and multiple receiving end pins extend in a third direction after passing through the limiting hole.

[0039] The circuit board is placed on a support tray, parallel to both the first and second directions; the connection area is positioned opposite the cutout portion; the first, second, and third directions are mutually perpendicular. This design facilitates the shaping of the optical transmitting and receiving components and the automatic insertion of the optical transmitting and receiving components into the circuit board.

[0040] In some possible implementations, the insertion device includes a second motion platform, a gripping device, and a second vision module; the gripping device is mounted on the second motion platform, which is used to drive the gripping device to move along a first direction, a second direction, and a third direction.

[0041] The gripping device is used to grip the light reflection receiving component.

[0042] The second vision module includes a third camera and a fourth camera. The third camera is fixedly set and is used to capture images of multiple transmitting pins and multiple receiving pins in the light transmitting and receiving components captured by the grasping device.

[0043] The fourth camera is mounted on the gripping device and is used to photograph the connection area of ​​the circuit board during the insertion of the light transmitting and receiving components and the circuit board.

[0044] With this design, the insertion device can automatically insert the light transmitting and receiving components and the circuit board using a dual-camera scheme.

[0045] In some possible implementations, the insertion device includes a second motion platform, a third motion platform, a gripping device, a lifting device, and a second vision module; the gripping device is mounted on the second motion platform, which drives the gripping device to move along a first direction and a third direction; the gripping device is used to grip the light reflection receiving component.

[0046] The lifting device is mounted on the third motion platform, which is used to drive the lifting device to move in the second and third directions; the lifting device is used to lift the circuit board.

[0047] The second vision module includes a third camera, which is fixedly set up and used to photograph multiple transmitting pins and multiple receiving pins in the light transmitting and receiving assembly captured by the grasping device; it is also used to photograph the connection area of ​​the circuit board during the insertion process of the light transmitting and receiving assembly and the circuit board.

[0048] With this design, the insertion device can automatically insert the light transmitting and receiving components and the circuit board using a single-camera solution.

[0050] This automatic insertion method includes:

[0051] The optical transmitting and receiving components are shaped. In the shaped optical transmitting and receiving components, multiple transmitting pins are bent to the side where multiple receiving pins are located. Both the multiple transmitting pins and the multiple receiving pins are parallel to a third direction. In the third direction, the lengths of the multiple transmitting pins are different, and the lengths of the multiple receiving pins are all shorter than the lengths of the multiple transmitting pins.

[0052] Control the insertion of multiple terminal pins into the corresponding first pin holes one by one, from longest to shortest;

[0053] After the multiple terminal pins are installed, control the insertion of multiple terminal pins into multiple second pin holes.

[0078] An optical network terminal (ONU), commonly known as an optical modem, is a key node device in a passive optical network (PON) and is widely used in FTTH (Fiber To The Home) and FTTR (Fiber To The Room) scenarios.

[0079] like Figure 1 As shown, an optical network terminal 100 provided by related technology includes a printed circuit board (PCB) 2 and a bi-directional optical subassembly (BOSA) 1 inserted into the PCB 2. The BOSA 1 is a single-fiber bidirectional optical device, such as... Figure 2 and Figure 3 As shown, it may include a Transmitter Optical Subassembly (TOSA) 4, a Receiver Optical Subassembly (ROSA) 5, a mounting base 3, an optical fiber adapter 6, and a filter 7.

[0080] In the optical transmitter-receiver assembly 1, the optical transmitter assembly 4 is the transmitting device used to convert electrical signals into optical signals (E / O). For example... Figure 4 As shown, the optical emitting component 4 adopts a coaxial package (also known as a TO-CAN package or TO package), including a transmitting base 9, a transmitting cap 8, a laser 11, and multiple transmitting pins 10. In this paper, the central axis of the optical emitting component 4 is referred to as the transmitting axis La. The transmitting cap 8 is positioned along the transmitting axis La on one side of the transmitting base 9, and the transmitting base 9 and the transmitting cap 8 cooperate to form a transmitting package space. The laser 11 is mounted on the transmitting base 9 within the transmitting package space.

[0081] Multiple transmitter pins 10 extend parallel to the transmitter axis La and are mounted on the transmitter base 9. These multiple transmitter pins 10 extend from the outside of the transmitter packaging space through the transmitter base 9 into the interior. The laser 11 is connected to the multiple transmitter pins 10 via metal leads.

[0082] Optical receiver component 5 is a receiving device used to convert optical signals into electrical signals (O / E). For example... Figure 5 As shown, the optical receiver assembly 5 also adopts a coaxial package, including a receiver base 13, a receiver cap 12, a photodetector 15, and multiple receiver pins 14. In this paper, the central axis of the optical receiver assembly 5 is referred to as the receiver axis Lb. The receiver cap 12 is disposed along the receiver axis Lb on one side of the receiver base 13, and the receiver base 13 and the receiver cap 12 cooperate to form a receiver packaging space. The photodetector 15 is disposed on the receiver base 13 within the receiver packaging space.

[0083] Multiple receiver pins 14 extend parallel to the receiver axis Lb and are mounted on the receiver base 13. These multiple receiver pins 14 extend from the outside of the receiver package space through the receiver base 13 into the interior. A photodetector 15 is connected to the multiple receiver pins 14 via metal leads.

[0084] Please continue to refer to this. Figure 2 and Figure 3 The mounting base 3 in the optical transmitter-receiver assembly 1 is used to connect and mount the optical transmitter assembly 4, the optical receiver assembly 5, the filter 7, and the fiber optic adapter 6. The mounting base 3 has a first optical channel extending along a first axis L1, with a first connection port and a second connection port at its two ends on the first axis L1, respectively. The optical transmitter assembly 4 is disposed in the first connection port, with its transmitting axis La coinciding with the first axis L1, and its transmitting base 9 located at the end furthest from the second connection port. The fiber optic adapter 6 is disposed in the second connection port for connecting an external optical fiber. The mounting base 3 also has a second optical channel extending along a second axis L2 on one side of the first optical channel, with the second axis L2 perpendicular to the first axis L1, and the second optical channel communicating with the first optical channel. The end of the second optical channel furthest from the first optical channel is a third connection port, in which the optical receiver assembly 5 is disposed, with its receiving axis Lb coinciding with the second axis L2, and its receiving base 13 located at the side furthest from the third connection port.

[0085] The filter 7 is positioned at the intersection of the first and second optical channels to allow signal light emitted by the optical emitting assembly 4 to pass through. This signal light passing through the filter 7 can then be incident on the external optical fiber connected to the optical fiber adapter 6. The filter 7 also reflects the signal light incident from the optical fiber adapter 6 to the optical receiving assembly 5.

[0086] For the optical transmitter-receiver assembly 1 using the above design, the direction of the first axis L1 is conventionally referred to as the length direction, and its structure, position, and orientation are described with reference to this. As can be seen from the above description, in the optical transmitter-receiver assembly 1, the optical transmitter assembly 4 is located at one end along the length direction, and the transmitting end base 9 is located at the end along the length direction. The optical receiver assembly 5 is located on the side, and the receiving end base 13 is located on the outside along the direction of the second axis L2. That is, multiple transmitting pins 10 are located at the end of the optical transmitter-receiver assembly 1 along the length direction, and multiple receiving pins 14 are located on the side of the optical transmitter-receiver assembly 1; and the multiple transmitting pins 10 and multiple receiving pins 14 extend in mutually perpendicular directions.

[0087] like Figure 6 and Figure 7 As shown, the circuit board 2 in the optical network terminal 100 includes a connection area 18 for connecting the optical transmitter / receiver assembly 1. This connection area 18 includes a first sub-connection area 16 and a second sub-connection area 17. The first sub-connection area 16 has multiple first pin holes 19 that mate with multiple transmitting pins 10, and the second sub-connection area 17 has multiple second pin holes 20 that mate with multiple receiving pins 14. Each of the multiple first pin holes 19 corresponds one-to-one with each transmitting pin 10, and each of the multiple second pin holes 20 corresponds one-to-one with each receiving pin 14. When the optical transmitter / receiver assembly 1 is inserted into the circuit board 2, as... Figure 7 As shown, the light transmitting and receiving component 1 is positioned on one side of the circuit board 2 with its length direction (first axis L1) parallel to the circuit board 2, and the second axis L2 is perpendicular to the circuit board 2; the receiving end base 13 faces the circuit board 2 and is relatively close. Multiple receiving end pins 14 extend directly into multiple second pin holes 20, and multiple transmitting end pins 10 are bent at 90 degrees and extend into multiple first pin holes 19.

[0088] However, due to the large number of transmitting pins 10, which are all flexible pins with low rigidity and slender shape, they are prone to bending, clustering, and crossing, making it impossible to extend them in the designed direction. This makes it difficult to automate the insertion of the optical transmitting / receiving component 1 and the circuit board 2 using automated equipment. In related technologies, the insertion of the optical transmitting / receiving component 1 and the circuit board 2 typically relies on manual operation, resulting in low insertion efficiency. Furthermore, this prevents the automated assembly line of the optical network terminal 100 from functioning smoothly, hindering the improvement of the overall assembly efficiency of the optical network terminal 100.

[0089] Based on this, embodiments of this application provide a shaping device, an automatic insertion device, and an automatic insertion method to improve the above-mentioned problems.

[0090] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0098] This application provides an automatic insertion device for the automatic insertion of an optical transmitting and receiving component 1 and a circuit board 2. For ease of description, this document uses a first direction, a second direction, and a third direction that are mutually perpendicular to each other as references, and takes the third direction as the height direction (i.e., the vertical direction) as an example to explain the structure and working principle of the automatic insertion device.

[0099] In this embodiment, as Figure 8As shown, the automatic insertion device 21 includes a shaping device 22, an insertion device 23, and a transfer device 26; wherein the shaping device 22 and the insertion device 23 are arranged at intervals in the second direction Y. The transfer device 26 includes a carrying tray 24 and a conveying system 25. The carrying tray 24 is used to carry the light emitting and receiving component 1 and the circuit board 2. The conveying system 25 extends between the shaping device 22 and the insertion device 23 along the second direction Y. The carrying tray 24 is placed on the conveying system 25, and the conveying system 25 can drive the carrying tray 24 to move along the second direction Y. During the movement of the carrying tray 24 along the second direction Y, it can drive the light emitting and receiving component 1 and the circuit board 2 to flow from the shaping device 22 to the insertion device 23.

[0100] For ease of description, the position where the carrying pallet 24 is transferred to the shaping device 22 is referred to as the shaping position in this article. Figure 8 As shown in Figure 24A; the position where the carrying tray 24 is transferred to the insertion device 23 is called the insertion position, such as... Figure 8 As shown in Figure 24B, when the carrier tray 24 is in the shaping position, the shaping device 22 can perform shaping processing on the light emitting and receiving component 1 on the carrier tray 24. When the carrier tray 24 is in the insertion position, the insertion device 23 can perform insertion processing on the light emitting and receiving component 1 and the circuit board 2 on the carrier tray 24.

[0101] like Figure 9 and Figure 10 As shown, the carrier tray 24 provided in this embodiment includes a first carrier portion 27 and a second carrier portion 28. The first carrier portion 27 is used to carry the light transmitting and receiving assembly 1, and includes a limiting seat 29 and a limiting hole 30 extending along the third direction Z. When the light transmitting and receiving assembly 1 is placed on the first carrier portion 27, the light receiving assembly 5 is engaged in the limiting seat 29, and multiple receiving pins 14 extend along the third direction Z after passing through the limiting hole 30. Through the engagement of the light receiving assembly 5 and the limiting seat 29, the light transmitting and receiving assembly 1 is fixed on the carrier tray 24 in an attitude where its length direction (first axis L1) is parallel to the first direction X, and the transmitting base 9 with multiple transmitting pins 10 faces the side where the shaping device 22 is located.

[0102] Please continue to refer to this. Figure 9 The second support portion 28 in the support tray 24 is used to support the circuit board 2, including a plate-like structure parallel to the first direction X and the second direction Y, and a cutout portion penetrating the plate-like structure along the third direction Z. When the circuit board 2 is placed on the first support portion 27, the circuit board 2 lies flat on the plate-like structure, and the connection area 18 is located opposite the cutout portion. That is, the connection area 18 is not obstructed by the second support portion 28.

[0103] The first support portion 27 in the support tray 24 can be located near the edge of the shaping device 22 to facilitate the shaping process of the optical transmitting and receiving assembly 1 by the shaping device 22. For the optical transmitting and receiving assembly 1 connected with pigtails and fiber optic connectors, the support tray 24 is also provided with a structure for fixing and storing pigtails and fiber optic connectors.

[0104] In this embodiment, the carrier tray 24 includes at least two first carrier portions 27 and at least two second carrier portions 28, for simultaneously carrying multiple optical transmitting and receiving components 1 and circuit boards 2.

[0105] Please refer to Figure 8 , Figure 11 and Figure 12 The shaping device 22 is disposed on one side of the conveying system 25 and includes a first motion platform 31, a straightening assembly 33, a bending assembly 32, a first shearing assembly 37, a second shearing assembly 50, and a first vision module 36. The first motion platform 31 can move along a first direction X and a second direction Y. In some embodiments, the first motion platform 31 can also rotate about an axis parallel to a third direction Z. When the carrier tray 24 moves to the shaping position, the first motion platform 31 can use the above-mentioned movement to drive the shaping device 22 to a working position where it can perform shaping processing on the light emitting and receiving assembly 1 on the carrier tray 24.

[0106] In the shaping device 22, the straightening assembly 33 is mounted on the first motion platform 31 and is used to straighten the multiple transmitting pins 10 of the light transmitting and receiving assembly 1 along the first direction X. Figure 13 , Figure 14 and Figure 15 As shown, the straightening assembly 33 includes a straightening structure 40, a first driving device 41, a first mounting structure 42, and a second driving device 43. Both the straightening structure 40 and the first driving device 41 are mounted on the first mounting structure 42. The straightening structure 40 includes a first comb tooth 38 and a second comb tooth 39. The first comb tooth 38 extends along a fourth direction and has a first comb tooth groove 44 extending along the fourth direction at its end. The second comb tooth 39 extends along a fifth direction and has a second comb tooth groove 45 extending along the fifth direction at its end. The fourth and fifth directions are two intersecting directions perpendicular to the first direction X. Both the first comb tooth 38 and the second comb tooth 39 are connected to the first driving device 41, which drives the first comb tooth 38 to move along the fourth direction and drives the second comb tooth 39 to move along the fifth direction.

[0107] The first mounting structure 42 is mounted on the second drive device 43, which is mounted on the first motion platform 31. Alternatively, both the first mounting structure 42 and the second drive device 43 are mounted on the first motion platform 31. The second drive device 43 drives the first mounting structure 42 to rotate about a third axis parallel to the first direction X. The first mounting structure 42 drives the straightening structure 40 and the first drive device 41 to rotate about the third axis, thereby achieving the purpose of driving the fourth and fifth directions to rotate about their intersection.

[0108] When the straightening assembly 33 combs the teeth of the multiple transmitting pins 10 of the light transmitting and receiving assembly 1, the first motion platform 31 drives the straightening assembly 33 to move in the first direction X. During its movement along the first direction X, the straightening assembly 33 has a tooth insertion position and a straightening position. In the first direction X, the tooth insertion position is aligned with the root region of the multiple transmitting pins 10 in the light transmitting and receiving assembly 1, while the straightening position is farther away from the light transmitting and receiving assembly 1 relative to the tooth insertion position.

[0109] When the straightening component 33 is in the comb insertion position, the intersection of the fourth and fifth directions is located at the center of the roots of multiple transmitting pins 10 in the light transmitting and receiving component 1, which is also the location of the first axis L1. Driven by the first driving device 41, the first comb tooth 38 moves along the fourth direction toward the intersection of the fourth and fifth directions, inserting into the roots of the multiple transmitting pins 10 during the movement. The multiple transmitting pins 10 enter the first comb tooth groove 44 of the first comb tooth 38. Driven by the first driving device 41, the second comb tooth 39 moves along the fifth direction toward the intersection of the fourth and fifth directions, inserting into the roots of the multiple transmitting pins 10 during the movement. The multiple transmitting pins 10 enter the second comb tooth groove 45 of the second comb tooth 39. The first comb tooth 38 and the second comb tooth 39 intersect at the roots of the multiple transmitting pins 10 in the light transmitting and receiving component 1, as shown below. Figure 15 As shown, in the first comb tooth 38 and the second comb tooth 39 after crossing, the first comb tooth groove 44 and the second comb tooth groove 45 will come together to form a straightening hole 46 surrounding each hairpin 10.

[0110] As described above regarding the optical transmitting and receiving component 1, the multiple transmitting pins 10 are all slender and flexible pins, which are prone to bending, clustering, and crossing, especially at the ends far from the roots. This makes it difficult for the multiple transmitting pins 10 to extend in the designed extension direction (first direction X), which in turn adversely affects subsequent insertion. Considering that the roots of the multiple transmitting pins 10 are close to the connected transmitting base 9 and have relatively good rigidity, the first comb tooth 38 and the second comb tooth 39 are chosen to cross and extend into the roots of the multiple transmitting pins 10, forming a pin straightening hole 46 surrounding each transmitting pin 10.

[0111] Furthermore, the formation principle of the pin straightening hole 46 shows that the number and arrangement of the first comb grooves 44 in the first comb member 38 are related to the projection of the multiple hairpins 10 onto a reference plane perpendicular to the fourth direction, and the number and arrangement of the second comb grooves 45 in the second comb member 39 are related to the projection of the multiple hairpins 10 onto a reference plane perpendicular to the fifth direction. In other words, the number and arrangement of the multiple hairpins 10 correspond to the number and arrangement of the first comb grooves 44 in the first comb member 38, the number and arrangement of the second comb grooves 45 in the second comb member 39, and the fourth and fifth directions.

[0112] For different light-emitting and receiving components 1 with the same number of transmitting pins 10, the arrangement of the multiple transmitting pins 10 may rotate and change around the first axis L1 (parallel to the first direction X). In this case, the straightening component 33, which is fixed in the fourth and fifth directions, cannot be adapted to the different light-emitting and receiving components 1. Based on this, the straightening component 33 provided in this embodiment is also provided with a second driving device 43. The second driving device 43 can drive the first mounting structure 42 to rotate around the third axis. During the rotation of the first mounting structure 42, the first comb tooth 38 and the second comb tooth 39 are inserted in the direction of the multiple transmitting pins 10, that is, the fourth and fifth directions, which will rotate around the third axis, thereby adapting to the different light-emitting and receiving components 1 and improving the applicability of the straightening component 33 and the automatic insertion device 21.

[0113] like Figure 11 and Figure 12 As shown, the shaping device 22 also includes a first vision module 36, comprising a first camera 35 and a second camera 34. The first camera 35 is mounted on the first motion platform 31, located above the intersection of the first comb teeth 38 and the second comb teeth 39 (i.e., the roots of the multiple transmitting pins 10 in the light transmitting and receiving assembly 1). The shooting direction of the first camera 35 is parallel to the third direction Z and faces the side where the first comb teeth 38 and the second comb teeth 39 intersect. The second camera 34 is mounted on the first motion platform 31 and is positioned opposite the intersection of the first comb teeth 38 and the second comb teeth 39 in the first direction X. In the first direction X, the second camera 34 is located away from the conveying system 25 relative to the intersection of the first comb teeth 38 and the second comb teeth 39.

[0114] When the first vision module 36 moves to the working position with the first motion platform 31, the first camera 35 is positioned above the light emitting and receiving assembly 1 on the support tray 24, and can capture a top image of the light emitting and receiving assembly 1. The second camera 34 is opposite to the transmitting end base 9 in the light emitting and receiving assembly 1, that is, opposite to the roots of the multiple transmitting end pins 10; it can capture an image of the transmitting end base 9. It can be seen that the first vision module 36 can obtain the top and end images of the light emitting and receiving assembly 1, and based on the top and end images, information such as the pose and extension state of the multiple transmitting end pins 10 can be obtained; based on the above information, it is beneficial for the straightening structure 40 to be accurately inserted between the multiple transmitting end pins 10.

[0115] In some embodiments, the first vision module 36 includes a first camera 35 and a reflecting device. The first camera 35 is the same as in the above embodiments, and the reflecting device is mounted on the first motion platform 31 and is disposed opposite to the first comb tooth 38 and the second comb tooth 39 at an intersection position in the first direction X. In the first direction X, the reflecting device is located away from the conveying system 25 relative to the intersection position of the first comb tooth 38 and the second comb tooth 39.

[0116] When the first vision module 36 moves to the working position with the first motion platform 31, the first camera 35 is positioned above the light emitting and receiving assembly 1 on the support tray 24, and can capture a top image of the light emitting and receiving assembly 1. The reflective device is opposite to the transmitting end base 9 in the light emitting and receiving assembly 1, that is, opposite to the roots of the multiple transmitting pins 10. The reflective device can reflect the transmitting end base 9 of the light emitting and receiving assembly 1 to the first camera 35, and the first camera 35 can also capture an end image of the light emitting and receiving assembly 1. It can be seen that the first vision module 36 can obtain the top image and the end image of the light emitting and receiving assembly 1, and based on the top image and the end image, information such as the pose and extension state of the multiple transmitting pins 10 can be obtained; based on the above information, it is beneficial for the straightening structure 40 to be accurately inserted between the multiple transmitting pins 10.

[0117] After the straightening structure 40 forms straightening holes 46 around the roots of multiple hair tips 10, the first motion platform 31 drives the straightening assembly 33 to move along the first direction X from the tooth insertion position toward the straightening position. During this movement, the straightening holes 46 can straighten the surrounding hair tips 10 along the first direction X. After being straightened by the straightening assembly 33, the multiple hair tips 10 are all in a state parallel to the first direction X.

[0118] Please refer to Figure 11 , Figure 12 and Figure 16The shaping device 22 also includes a bending assembly 32, a first cutting assembly 37, and a second cutting assembly 50, all of which are mounted on the first motion platform 31. When the first motion platform 31 moves the shaping device 22 to the working position, and the straightening assembly 33 straightens the multiple transmitting leads 10 of the light emitting and receiving assembly 1, the bending assembly 32 bends the straightened transmitting leads 10 toward the side containing the multiple receiving leads 14, and bends them into a state parallel to the multiple receiving leads 14, i.e., parallel to the third direction Z. The first cutting assembly 37 cuts the bent transmitting leads 10 into different lengths to facilitate the insertion of the light emitting and receiving assembly 1 and the circuit board 2 (see the description of insertion below).

[0119] like Figure 16 As shown, the bending assembly 32 includes a bending element 47, a second mounting structure 48, a third drive device, and a fourth drive device. Both the bending element 47 and the third drive device are mounted on the second mounting structure 48. The second mounting structure 48 is mounted on the fourth drive device, which is mounted on the first motion platform 31. Alternatively, both the second mounting structure 48 and the fourth drive device are mounted on the first motion platform 31.

[0120] like Figure 17 As shown in part (a), the bending member 47 includes a bending plate 51 and a bending step 54. The bending plate 51 is a plate-like structure, including a first side 52 and a second side 53 disposed opposite each other in the thickness direction. The bending step 54 is disposed on the first side 52. The bending member 47 also includes a plurality of bending holes 55 penetrating the bending step 54 and the bending plate 51 along the thickness direction of the bending plate 51. The number of bending holes 55 is the same as the number of multiple transmitting pins 10 in the adapted optical transmitting and receiving assembly 1, and the arrangement position of the bending holes 55 is the same as the arrangement position of the multiple transmitting pins 10 designed in the transmitting base 9, that is, the same as the arrangement position of the multiple transmitting pins 10 after straightening.

[0121] The bending member 47 is connected to a third driving device, which can drive the bending member 47 to rotate around a fourth axis. The fourth axis is perpendicular to the thickness direction of the bending plate 51 and parallel to the second direction Y, that is, perpendicular to the first direction X. The bending member 47 has an upright state and a bent state during its rotation around the fourth axis. When the bending member 47 is in the upright state, the thickness direction of the bending plate 51 is parallel to the first direction X, and the first side surface 52 of the bending plate 51 is close to the light emitting and receiving component 1. When the bending member 47 is in the bent state, the thickness direction of the bending plate 51 is parallel to the third direction Z, and the first side surface 52 is located above the second side surface 53.

[0122] When the bending assembly 32 bends the multiple transmitting leads 10 of the light transmitting and receiving assembly 1, the bending member 47 is first placed in an upright state. In this case, the bending holes 55 on the bending member 47 are aligned with the multiple transmitting leads 10 straightened by the straightening assembly 33. Subsequently, the first motion platform 31 drives the upright bending member 47 to move along the first direction X toward the side closer to the light transmitting and receiving assembly 1. During the above-mentioned movement, the upright bending member 47 allows the multiple transmitting leads 10 to pass into the corresponding multiple bending holes 55 respectively. When the distance of the multiple transmitting leads 10 into the bending member 47 meets the requirements, the first motion platform 31 can stop moving. The third drive device can drive the bending member 47 to rotate around the fourth axis after the first motion platform 31 stops moving. During the rotation of the bending member 47 around the fourth axis, it changes from an upright state to a bent state. During the process of the bending member 47 moving from an upright state to a bent state, the multiple starting pins 10 are bent towards the side where the multiple ending pins 14 are located under the action of the bending member 47, and bent into a state parallel to the multiple ending pins 14, that is, a state parallel to the third direction Z.

[0123] As can be seen from the above description, both the upright bent component 47 and the second camera 34 (or reflective device) in the first vision module 36 are directly opposite the transmitting end base 9 of the light emitting and receiving assembly 1. Based on this, in this embodiment, the bending assembly 32 is positioned between the transfer device 26 and the second camera 34 (or reflective device) in the first direction X. Furthermore, when the bending assembly 32 is not operating, the bent component 47 can be controlled to be in a bent state, thereby avoiding the second camera 34 (or reflective device). Since the detection of the light emitting and receiving assembly 1 by the first vision module 36 and the bending of the multiple transmitting end pins 10 do not conflict in time, both can be ensured to function normally through the above method.

[0124] Please continue to refer to this. Figure 16 In the bending assembly 32 provided in this application embodiment, the fourth driving device is used to drive the second mounting structure 48 to move along the third direction Z. The second mounting structure 48 drives the bending member 47 and the third driving device to move along the third direction Z. Thus, after the bending member 47 bends the multiple starting pins 10, the bending member 47 can be removed from the multiple starting pins 10.

[0125] Because the optical transmitter / receiver assembly 1 has a relatively long number of transmitting pins 10 when it arrives, these long transmitting pins 10 are not conducive to insertion with the multiple first pin holes 19. Therefore, the transmitting pins 10 need to be shortened before the optical transmitter / receiver assembly 1 is inserted into the circuit board 2.

[0126] Based on this, such as Figure 12 and Figure 16As shown in the embodiment of this application, the shaping device 22 further includes a first cutting component 37, which includes a first cutting blade 49 and a fifth driving device. Both the first cutting blade 49 and the fifth driving device are mounted on a first motion platform 31. The fifth driving device is connected to the first cutting blade 49 and drives the first cutting blade 49 to move in a direction perpendicular to the third direction Z toward the bent multiple terminal leads 10. During its movement, the first cutting blade 49 can cut the multiple terminal leads 10.

[0127] In this embodiment, as Figure 18 As shown, the first cutting tool 49 is used to cut multiple bent terminal pins 10 into different lengths, and includes multiple active parts 57. One active part 57 in the first cutting tool 49 is used to cut one terminal pin 10, and different active parts 57 are located at different positions in the third direction Z in the first cutting tool 49. The number of active parts 57 in the first cutting tool 49 is related to the number of multiple terminal pins 10. Since the longest terminal pin 10 among the multiple terminal pins 10 of different lengths can be left uncut, the number of active parts 57 in the first cutting tool 49 can be one less than the number of multiple terminal pins 10. For example, if there are four terminal pins 10, when cutting the four terminal pins into different lengths, three active parts 57 can be provided in the first cutting tool 49, and the three active parts 57 are arranged at different positions in the third direction Z.

[0128] In some embodiments, since the length of the multiple transmitting pins 10 of the optical transmitting and receiving component 1 is relatively long when it is received, the longest transmitting pin 10 can also be cut to facilitate the insertion of the optical transmitting and receiving component 1 and the circuit board 2.

[0129] To facilitate the cutting of the first shearing blade 49 and to prevent the first shearing blade 49 from bending the hairline 10 during cutting, the bending member 47 remains stationary after bending multiple hairline 10s, and the bending member 47 is also provided with multiple shearing steps 56 on the second side 53 of the bending plate 51. Figure 17 Part (b) and Figure 19As shown, the number of shearing steps 56 is the same as the number of working parts 57 in the first shearing cutter 49, that is, the same as the number of the starting leads 10 to be cut. The shearing steps 56 correspond to the starting leads 10 to be cut, and the bending holes 55 corresponding to the starting leads 10 to be cut penetrate the bending steps 54, the bending plate 51, and the shearing steps 56 along the thickness direction of the bending plate 51. The starting leads 10 to be cut protrude from the end of the shearing steps 56 after passing through the bending holes 55. The shearing steps 56 extend from the second side 53 of the bending plate 51 along the thickness direction of the bending plate 51. In the thickness direction of the bending plate 51, the end face of the shearing steps 56 is flush with the cutting position of the starting leads 10.

[0130] like Figure 19 As shown, in the third direction Z, the actuating part 57 of the first cutting tool 49 is flush with the end face of the corresponding cutting step 56. When the first cutting tool 49 moves in a direction perpendicular to the third direction Z to cut the starting pin 10, the actuating part 57 cuts off the portion of the starting pin 10 that extends beyond the end face of the cutting step 56.

[0131] After the first lead-cutting assembly 37 completes the lead-cutting, the fifth drive device drives the first lead-cutting cutter 49 to move to the initial position. The fourth drive device drives the bending member 47 to move along the third direction Z to disengage from the multiple transmitting leads 10, so that the light transmitting and receiving assembly 1 can continue to flow with the carrying tray 24.

[0132] After the shaping device 22 shapes the light transmitting and receiving component 1, the multiple transmitting pins 10 in the light transmitting and receiving component 1 are bent toward the side where the multiple receiving pins 14 are located, so as to be parallel to the multiple receiving pins 14; and the multiple transmitting pins 10 have different lengths, and in the third direction Z, the ends of the multiple transmitting pins 10 are at different positions.

[0133] Since the length of the multiple receiving pins 14 is usually quite long when the optical transmitting and receiving assembly 1 is received, it is necessary to shorten the multiple receiving pins 14 before insertion. The shortened multiple receiving pins 14 are easier to insert into the multiple second pin holes 20.

[0134] Based on this, the automatic insertion device 21 provided in this application embodiment further includes a second lead-cutting assembly 50, which is used to shorten multiple terminal leads 14. The second lead-cutting assembly 50 can be disposed in the shaping device 22, the insertion device 23, or the transfer device 26 located between the shaping device 22 and the insertion device 23.

[0135] In this embodiment, as Figure 12 , Figure 16 and Figure 20As shown, the second cutting component 50 is disposed in the shaping device 22, including a second cutting blade 58 and a sixth driving device 59. The sixth driving device 59 is connected to the second cutting blade 58 and is used to drive the second cutting blade 58 to move in a direction perpendicular to the multiple terminal tubes 14. During the movement, the multiple terminal tubes 14 can be cut.

[0136] In some embodiments, the second lead-cutting assembly 50 includes a second lead-cutting blade 58 and a trigger structure. The second lead-cutting blade 58 is mounted on the bottom side of the first support portion 27, that is, the side opposite to the light-emitting and receiving assembly 1. The second lead-cutting blade 58 can move relative to the first support portion 27, and the initial position of the movement is located on one side of the limiting hole 30. As can be seen from the above description, when the light-emitting and receiving assembly 1 is placed on the first support portion 27, the multiple receiving leads 14 are located on one side of the second lead-cutting blade 58 in its initial position.

[0137] The trigger structure is located on the side of the insertion device 23 near the shaping device 22. When the conveying system 25 drives the carrying tray 24 to move to the insertion device 23 along the second direction Y, the trigger structure will push the second cutting blade 58 to move. Under the drive of the trigger structure, the second cutting blade 58 will move toward the limiting hole 30, that is, toward the multiple end tube pins 14, thereby achieving the purpose of cutting the multiple end tube pins 14.

[0138] The multiple receiving pins 14, after being shortened by the second pin-cutting assembly 50, are all of the same length and shorter in the third direction Z than the multiple transmitting pins 10, after being shortened by the first pin-cutting assembly 37. In other words, in the third direction Z, the ends of the multiple transmitting pins 10 of different lengths are all farther away from the receiving base 13 relative to the multiple receiving pins 14. This design facilitates the insertion of the optical transmitting / receiving assembly 1 into the circuit board 2 (this part can be found in the description of the insertion device 23 below).

[0139] Please continue to refer to this. Figure 8 The automatic insertion equipment 21 also includes an insertion device 23, which is disposed on one side of the conveying system 25. It can be located on the same side of the conveying system 25 as the shaping device 22, or on a different side of the conveying system 25.

[0140] In the insertion device 23 provided in the embodiments of this application, such as Figure 21 As shown, the system includes a second motion platform 60, a gripping device 61, and a second vision module 64. The second motion platform 60 can move along a first direction X, a second direction Y, and a third direction Z. When the carrier tray 24 moves to the insertion position, the second motion platform 60 can use the aforementioned movement to move the insertion device 23 to a working position where it can perform insertion processing on the light emitting and receiving component 1 and the circuit board 2 on the carrier tray 24.

[0141] like Figure 21 As shown, the gripping device 61 is used to grip the light emitting and receiving component 1 on the carrying tray 24, and can be a robotic arm with mechanical grippers. The gripping device 61 is mounted on the second motion platform 60, which can drive the gripping device 61 to move in three-dimensional space, thereby accurately gripping the light emitting and receiving component 1 on the carrying tray 24, and also inserting the gripped light emitting and receiving component 1 into the circuit board 2.

[0142] Please continue to refer to this. Figure 21 The second vision module 64 includes a third camera 62 and a fourth camera 63. The third camera 62 is fixedly mounted on one side of the second motion platform 60, with its shooting direction parallel to the third direction Z and facing the side where the grasping device 61 is located. When the grasping device 61 grasps the light emitting and receiving component 1, it can move the light emitting and receiving component 1 within the shooting area of ​​the third camera 62. The third camera 62 can capture a bottom image of the light emitting and receiving component 1, which includes multiple transmitting pins 10 and multiple receiving pins 14. Based on this bottom image, the position information of the multiple transmitting pins 10 and multiple receiving pins 14 can be obtained; this position information is referred to as pin position information.

[0143] A fourth camera 63 is mounted on the gripping device 61, with its shooting direction parallel to the third direction Z and facing the gripping side of the gripping device 61. The fourth camera 63 can capture images of the top of the carrying tray 24 when the gripping device 61 grips the light emitting and receiving component 1. The position information of the light emitting and receiving component 1 can be obtained from the captured images, which is beneficial for the accurate gripping of the gripping device 61.

[0144] When the gripping device 61 moves the gripped light emitting and receiving component 1 to the top of the circuit board 2 for insertion, the fourth camera 63 can also take pictures of the circuit board 2 to obtain a top image of the circuit board 2. Based on the top image, the position information of multiple first pin holes 19 and multiple second pin holes 20 in the connection area 18 of the circuit board 2 can be obtained. This position information is referred to as pin hole position information in this paper.

[0145] Based on the obtained pin position information and pin hole position information, the insertion device 23 can insert multiple pins (including multiple transmitting pins 10 and multiple receiving pins 14) of the optical transmitting and receiving component 1 into multiple pin holes (including multiple first pin holes 19 and multiple second pin holes 20) in the circuit board 2 to realize the insertion of the optical transmitting and receiving component 1 into the circuit board 2.

[0146] During the insertion process of the optical transmitter / receiver assembly 1 and the circuit board 2, the gripping device 61 will drive the optical transmitter / receiver assembly 1 to gradually approach the circuit board 2 along the third direction Z. Since the length of the multiple transmitting pins 10 is longer than the length of the multiple receiving pins 14, that is, the ends of the multiple transmitting pins 10 are closer to the circuit board 2 than the ends of the multiple receiving pins 14; therefore, the gripping device 61 first inserts the multiple transmitting pins 10 into the corresponding first pin holes 19, and then the gripping device 61 inserts the multiple receiving pins 14 into the corresponding second pin holes 20.

[0147] Since the multiple terminal pins 10 have different lengths, during the insertion process, the longest terminal pin 10 is first inserted into its corresponding first pin hole 19 using the gripping device 61. Then, the second longest terminal pin 10 is inserted into its corresponding first pin hole 19 using the controlled robotic arm. This process is repeated until all terminal pins 10 are inserted into their corresponding first pin holes 19 in order of length.

[0148] Since the multiple receiving pins 14 are of equal and relatively short length and have a good extension state along the third direction Z, after all the giving pins 10 are inserted, the multiple receiving pins 14 can be inserted into the multiple second pin holes 20 at once by the gripping device 61.

[0149] During the insertion process of the aforementioned optical transmitting and receiving component 1 and circuit board 2, the relative positional relationship between the pins (including transmitting pin 10 and multiple receiving pins 14) and pin holes (including first pin hole 19 and second pin hole 20) can be monitored in real time by the fourth camera 63. Based on this relative positional information, the movement of the optical transmitting and receiving component 1 can be finely adjusted by the gripping device 61, thereby further improving the alignment accuracy between the pins and pin holes and ensuring insertion quality and success rate.

[0150] After the optical transmitter / receiver component 1 is inserted onto the circuit board 2 using the insertion assembly, the multiple transmitting pins 10 and multiple receiving pins 14 extend significantly beyond the circuit board 2, exceeding the length required for subsequent soldering and fixing to the circuit board 2. Therefore, the automatic insertion device 21 provided in this embodiment further includes a third pin-cutting assembly. This third pin-cutting assembly is used to uniformly shorten the multiple receiving pins 14 and multiple transmitting pins 10 after the optical transmitter / receiver component 1 is inserted onto the circuit board 2, to facilitate subsequent soldering and fixing.

[0151] For example, the third shearing assembly is disposed below the carrier tray 24 in the insertion position, and includes a seventh drive device and a third shearing cutter. The seventh drive device is connected to the third shearing cutter, and the third shearing cutter, driven by the seventh drive device, cuts the multiple terminal pins 14 and multiple terminal pins 10 short in a unified manner.

[0152] To facilitate understanding of the working principle of the automatic insertion device 21 provided in the above embodiments, its working process will be described by way of example below.

[0153] 1. Place the light transmitting and receiving component 1 on the first support portion 27 in the support tray 24, and place the circuit board 2 on the second support portion 28 in the support tray 24.

[0154] 2. The carrying tray 24 moves to the shaping position under the drive of the conveying system 25. The straightening component 33 in the shaping device 22 straightens the multiple transmitting leads 10 in the light emitting and receiving component 1 along the first direction X. After straightening is completed, the bending component 32 bends the multiple leads. After bending is completed, the first cutting component 37 cuts the multiple leads 10 into different lengths. Then, the bending component 47 in the bending component 32 disengages from the multiple leads 10.

[0155] 3. The carrying tray 24 drives the light transmitting and receiving component 1 to move from the shaping position along the second direction Y toward the insertion position. When it is about to reach the insertion position, the second lead cutting component 50 works to cut the multiple receiving leads 14 short.

[0156] 4. The carrying tray 24 moves to the insertion position under the drive of the conveying system 25. The gripping device 61 in the insertion device 23 drives the light transmitting and receiving component 1 to be inserted into the circuit board 2. After the light transmitting and receiving component 1 is inserted into the circuit board 2, the third lead-cutting component can cut off multiple transmitting leads 10 and multiple receiving leads 14 in a unified manner.

[0157] This application also provides another insertion device 23, such as... Figure 22 As shown, the insertion device 23 includes a second motion platform 60, a gripping device 61, a third motion platform 66, a lifting device 65, and a second vision module 64. The gripping device 61 is mounted on the second motion platform 60, which drives the gripping device 61 to move along a first direction X and a third direction Z. The gripping device 61 is used to grip the light emitting and receiving assembly 1 on the carrying tray 24 and can be a robotic arm with mechanical grippers.

[0158] The lifting device 65 is mounted on the third motion platform 66, which drives the lifting device 65 to move along the second direction Y and the third direction Z. The lifting device 65 is used to lift the carrying pallet 24.

[0159] The second vision module 64 includes a third camera 62, which is fixedly mounted on one side of the second motion platform 60. The shooting direction is parallel to the third direction Z and is directed toward the side where the gripping device 61 is located.

[0160] The operation process of the insertion device 23 in this embodiment is as follows:

[0161] When the carrier tray 24 moves to the insertion position, the gripping device 61 grips the light emitting and receiving component 1 and can move the light emitting and receiving component 1 into the shooting area of ​​the third camera 62. The third camera 62 can capture a bottom image of the light emitting and receiving component 1, which includes multiple transmitting pins 10 and multiple receiving pins 14. Based on this bottom image, the pin position information can be obtained.

[0162] The lifting device 65 lifts the support tray 24 and can move the support tray 24 within the shooting area of ​​the third camera 62. The third camera 62 can capture an image of the bottom of the circuit board 2 on the support tray 24; based on this bottom image, the pin hole position information can be obtained.

[0163] After obtaining the pin position information and pin hole position information, the insertion device 23 can control the movement of the circuit board 2 and the light emitting and receiving component 1 to achieve insertion. Furthermore, the insertion is performed within the field of view of the third camera 62, which can capture and provide feedback on the insertion process in real time.

[0164] This application embodiment also provides an automatic insertion method 200, which is used for the automatic insertion of the optical transmitting and receiving component 1 and the circuit board 2, such as... Figure 23 As shown, the automatic insertion method 200 includes:

[0165] Step S10: Shape the optical transmitting and receiving components.

[0166] The shaping process here includes straightening, bending, and trimming the multiple transmitting pins 10, as well as trimming the multiple receiving pins 14. In the shaped optical transmitting and receiving assembly 1, the multiple transmitting pins 10 are bent to the side where the multiple receiving pins 14 are located, and both the multiple transmitting pins 10 and the multiple receiving pins 14 are parallel to the third direction Z. In the third direction Z, the lengths of the multiple transmitting pins 10 are different, and the lengths of the multiple receiving pins 14 are all shorter than the lengths of the multiple transmitting pins 10.

[0167] Step S20: Control the multiple starting pins to be inserted into the corresponding first pin holes one by one from longest to shortest.

[0168] Step S30: After the multiple terminal pins are installed, control the multiple terminal pins to be inserted into the multiple second pin holes.

[0169] The above method can be implemented by the automatic insertion device 21 provided in the embodiments of this application, or by one or more other devices capable of implementing the above steps.

[0170] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
