Description

Technical Field

[0001] This invention relates to the field of optical module production equipment technology, and in particular to a pick-and-place device for optical module chips. Background Technology

[0002] With the rapid development of 5G communication technology, the production scale of optical module chips used in the 5G field is also increasing. This has put forward further requirements for the production efficiency of optical module chips. At present, in order to improve the production efficiency of optical module chips, most of them adopt automated production lines. The entire production process is mechanically controlled. In the entire automated production line, the automated production of optical module chips is a key technology. In the existing technology, when picking up and transporting optical modules, most of them use external moving parts to drive the suction cup to pick up the optical modules, thereby achieving the purpose of picking up and transporting optical modules. However, when the suction cup picks up the optical module chip, the suction cup will generate an instantaneous reaction force on the optical module. This reaction force will act on the optical module. Since the optical module itself is a vulnerable part, this frequent reaction force can easily damage the optical module chip and reduce the final molding quality of the optical module chip. Summary of the Invention

[0003] The purpose of this invention is to provide a pick-and-place device for optical module chips, thereby solving one or more of the problems in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention provides a pick-up and transport device for optical module chips. The structure includes a lifting base, a lifting platform that can move up and down on the lifting base, and a driving component for driving the lifting platform to move up and down. The innovation is that the structure also includes a floating rod. The lifting platform is provided with a vertically penetrating movable groove. The floating rod is vertically floating inside the movable groove. A suction cup is installed at the bottom of the floating rod. An adjustment component for adaptively adjusting the vertical position of the floating rod is provided at the top of the floating rod.

[0005] The movable slot is equipped with a measuring element for the vertical floating distance of the floating rod, and the drive unit is equipped with a controller. The measuring element and the drive unit are electrically connected.

[0006] Furthermore, the aforementioned lifting seat is provided with a vertically downward fixed seat, and the outside of the fixed seat is provided with a flexible clamp. The direction of movement of the clamp is facing or away from the side of the fixed seat, and a movable groove is formed between the clamp and the side of the fixed seat.

[0007] The movable groove is equipped with three roller sets that abut against the floating rod. One roller set is set on the clamp, and the other two roller sets are set on the outer side of the fixed seat. The contact angle between the three roller sets on the floating rod is 120°. The roller set includes two rotating wheels that abut against the floating rod from top to bottom. The wheel surface of the rotating wheel is covered with a rubber surface.

[0008] Furthermore, the outer side of the aforementioned fixed base is provided with symmetrical inclined surfaces, and two other roller sets are rotatably mounted on the inclined surfaces with the axis of the rollers perpendicular to the inclined surfaces.

[0009] The fixture includes two parallel fixed plates and a U-shaped fixing frame. A roller assembly is rotatably disposed between the two fixed plates, with the wheel surface perpendicular to the outer side of the fixed base. An elastic groove is provided inside the fixed base, and the elastic groove is disposed opposite to the outer side of the fixed base. The two ends of the U-shaped fixing frame are fixed to the two fixed plates respectively. A buffer spring is connected between the top of the U-shaped fixing frame and the elastic groove. The two end faces of the U-shaped fixing frame are slidably connected to the two sides of the fixed base respectively.

[0010] Furthermore, the aforementioned measuring component includes an encoder disposed between two fixed plates, the encoder being located between two upper and lower rotating wheels and abutting against a floating rod.

[0011] Furthermore, the aforementioned adjusting component includes a limiting block fixed to the top of the floating rod and a connecting plate vertically disposed on the top of the lifting platform. A stabilizing rod extends outward from the limiting block and is rotatably disposed on the limiting block. A connecting block facing the connecting plate is disposed on the stabilizing rod. The connecting block is rotatably disposed on the stabilizing rod. Two magnets are disposed on the connecting block and the connecting plate, respectively. The two magnets are disposed opposite to each other and have opposite polarities.

[0012] Furthermore, the aforementioned lifting platform is equipped with a rotatable rotating rod, which is perpendicular to the stabilizing rod, and the ends of the rotating rod and the stabilizing rod are connected by a reversing gear.

[0013] Furthermore, the top of the aforementioned lifting platform is equipped with an angle adjustment plate. One end of the angle adjustment plate is equipped with a circular plate that fits around the floating rod. The floating rod is movably positioned inside the circular plate. The other end of the angle adjustment plate is equipped with a worm gear component. The worm gear component drives the angle adjustment plate to swing around the floating rod around the center. The floating rod rotates as the angle adjustment plate swings. The connecting plate and the rotating rod are both mounted on the angle adjustment plate.

[0014] Furthermore, the aforementioned worm gear component includes an arc-shaped gear disposed at the end of the angle adjustment plate, a drive motor, and a helical rod disposed at the output end of the drive motor, wherein the helical rod and the arc-shaped gear are meshed and connected.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention provides a pick-and-place device for optical module chips. At the instant the optical module and the suction cup come into contact, the suction cup generates an instantaneous reaction force on the optical module. At this moment, the vertical movement of the floating rod reduces the impact of this reaction force on the optical module, effectively protecting it. Simultaneously, during the vertical movement of the floating rod, an adjusting mechanism automatically adjusts the vertical position of the floating rod according to this reaction force, ensuring that the force of the vertical movement of the floating rod can self-adapt to this reaction force. This self-adaptive adjustment precisely counteracts the reaction force, improving the performance of the vertical movement of the floating rod and further enhancing the protection of the optical module.

[0017] This invention provides a pick-and-place device for optical module chips. During the cyclic pick-and-place process of the optical module by the suction cup, the measuring component continuously detects the vertical distance of the floating rod. By monitoring the vertical distance of the floating rod, the stability of the lifting platform's lifting motion can be determined. When the floating rod's vertical distance is too large, it indicates that the lifting platform's lifting motion is unstable. At this time, the measuring component transmits a signal to the controller, which controls the drive component to stop working, thereby avoiding irreversible damage to the optical module caused by the instability of the lifting platform's lifting motion and ensuring the protection of the optical module throughout the entire transportation process.

[0023] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0024] like Figures 1 to 5In one specific embodiment of the present invention, the structure includes a lifting seat 101, a lifting platform 102 that can move up and down on the lifting seat 101, and a driving component 103 that drives the lifting platform 102 to move up and down. The structure also includes a floating rod 1, a movable groove 2 that passes through the lifting platform 102, the floating rod 1 being vertically floating inside the movable groove 2, a suction cup 11 being installed at the bottom of the floating rod 1, and an adjusting component 3 that adaptively adjusts the up and down position of the floating rod 1 at the top of the floating rod 1.

[0025] The interior of the movable slot 2 is equipped with a measuring element for the vertical floating distance of the floating rod 1, and the drive component 103 is equipped with a controller. The measuring element and the drive component 103 are electrically connected.

[0026] In this invention, the working principle of the optical module's suction and handling is as follows: The driving component 103 drives the lifting platform 102 to move up and down. The up and down movement of the lifting platform 102 causes the floating rod 1 to move to the target position, so that the suction cup 11 approaches the optical module. When the suction cup 11 touches the optical module, the driving component 103 closes, the lifting platform 102 stops moving up and down, and the suction cup 11 picks up the optical module, realizing the suction and handling of the optical module. At the moment when the optical module and the suction cup 11 touch, the suction cup 11 will generate an instantaneous reaction force on the optical module. At this time, the vertical floating of the floating rod 1 can reduce the impact of this reaction force on the optical module, thereby effectively protecting the optical module. At the same time, during the vertical floating of the floating rod 1, the adjusting component 3 can automatically adjust the vertical position of the floating rod 1 according to this reaction force, ensuring that the vertical floating force of the floating rod 1 can adapt to this reaction force. This self-adaptive adjustment can just offset this reaction force, improving the performance of the vertical floating of the floating rod 1, and further improving the protection of the optical module.

[0027] In this invention, during the process of the suction cup 11 cyclically picking up and transporting the optical module, the measuring component continuously detects the vertical distance of the floating rod 1. By monitoring the vertical distance of the floating rod 1, it is possible to determine whether the lifting movement of the lifting platform 102 is stable. When the floating distance of the floating rod 1 is too large, it indicates that the lifting movement of the lifting platform 102 is unstable. At this time, the measuring component transmits a signal to the controller, and the controller controls the drive component 103 to stop working, thereby avoiding irreversible damage to the transport of the optical module caused by the instability of the lifting movement of the lifting platform 102, and ensuring the protection of the optical module throughout the entire transportation process.

[0028] In this invention, as a preferred embodiment, the lifting seat 101 is provided with a vertically downward fixed seat 4, and a movable clamp 5 is provided on the outside of the fixed seat 4. The direction of movement of the clamp 5 is facing or away from the side of the fixed seat 4, and a movable groove 2 is formed between the clamp 5 and the side of the fixed seat 4.

[0029] The interior of the movable groove 2 is provided with three roller groups 21 that abut against the floating rod 1. One roller group 21 is set on the clamp 5, and the other two roller groups 21 are set on the outer side of the fixed seat 4. The contact angle between the three roller groups 21 on the floating rod 1 is 120°. The roller group 21 includes two rotating wheels 211 that abut against the floating rod 1 from top to bottom. The wheel surface of the rotating wheel 211 is covered with a rubber surface.

[0030] In this invention, the floating process of the floating rod 1 in the movable slot 2 is as follows: when the floating rod 1 floats vertically up and down inside the movable slot 2, the rotating wheel 211 rotates with the floating rod 1 and abuts against the rotation of the floating rod 1 through the rubber surface. The rotation of the rotating wheel 211 ensures the stability of the floating rod 1 floating vertically up and down, avoids the phenomenon of arbitrary shaking during the floating process of the floating rod 1, and thus protects the optical module.

[0031] In this invention, as a preferred embodiment, the outer side of the fixed base 4 is provided with a symmetrical inclined surface 41, and the other two roller groups 21 are rotatably arranged on the inclined surface 41 with the axis of the rollers 211 perpendicular to the inclined surface 41.

[0032] The clamp 5 includes two parallel fixed plates 51 and a U-shaped fixing frame 52. A roller assembly 21 is rotatably disposed between the two fixed plates 51, and the wheel surface of the roller 211 is perpendicular to the outer side of the fixed seat 4. An elastic groove 42 is provided inside the fixed seat 4, and the elastic groove 42 is disposed opposite to the outer side of the fixed seat 4. The two ends of the U-shaped fixing frame 52 are respectively fixed to the two fixed plates 51. A buffer spring 104 is connected between the top of the U-shaped fixing frame 52 and the elastic groove 42. The two end faces of the U-shaped fixing frame 52 are slidably connected to the two sides of the fixed seat 4.

[0033] In this invention, under the elastic action of the buffer spring 104, the distance between the outer side of the fixed plate 51 and the fixed seat 4 is elastically adjustable, that is, the width of the movable groove 2 is adjustable. During the vertical floating process of the floating rod 1, this adjustable state of the movable groove 2 can flexibly adapt to the size of the floating rod 1 itself, avoiding the floating rod 1 from getting stuck inside the movable groove 2, and ensuring that the floating action of the floating rod 1 can always protect the suction cup 11 from picking up and transporting the optical module.

[0034] In this invention, as a preferred embodiment, the measuring component includes an encoder disposed between two fixed plates 51. The encoder is located between two upper and lower rotating wheels 211 and abuts against the floating rod 1. During the vertical floating process of the floating rod 1, the encoder is driven to rotate. Based on the rotation of the encoder, the vertical floating distance of the floating rod 1 can be detected.

[0035] In this invention, as a preferred embodiment, the specific structure of the adjusting member 3 is as follows: The adjusting member 3 includes a limiting block 31 fixed to the top of the floating rod 1 and a connecting plate 32 vertically disposed on the top of the lifting platform 102. The limiting block 31 extends outward with a stabilizing rod 33, which is rotatably disposed on the limiting block 31. The stabilizing rod 33 is provided with a connecting block 331 facing the connecting plate 32. The connecting block 331 is rotatably disposed on the stabilizing rod 33. The connecting block 331 and the connecting plate 32 are respectively provided with two magnet blocks 105, which are arranged opposite to each other and have opposite polarities.

[0036] In this invention, the stabilizing rod 33 moves upward accordingly based on the upward floating distance of the floating rod 1. Since the connecting block 331 and the connecting plate 32 are provided with magnets 105 of opposite polarities, the connecting block 331 and the connecting plate 32 are always in a relative state. Therefore, during the upward movement of the stabilizing rod 33, the connecting block 331 rotates adaptively at an angle on the stabilizing rod 33, ensuring that the connecting block 331 and the connecting plate 32 can remain in a relative state. The upward movement of the stabilizing rod 33 shortens the relative distance between the connecting block 331 and the connecting plate 32. However, due to the opposite polarities of the two magnets 105, there is an opposite repulsive force between the connecting plate 32 and the connecting block 331. This opposite magnetic repulsive force is used to counteract the force when the connecting block 331 and the connecting plate 32 approach each other, ensuring that the floating rod 1 can always move up and down adaptively according to the external reaction, without the connecting plate 32 and the connecting block 331 colliding and causing the floating rod 1 to be unable to continue to float upward.

[0037] In this invention, as a preferred embodiment, the lifting platform 102 is provided with a rotatable rotating rod 6, the rotating rod 6 and the stabilizing rod 33 are perpendicular to each other, and the ends of the rotating rod 6 and the stabilizing rod 33 are connected by a reversing gear. When the floating rod 1 floats upward, the stabilizing rod 33 moves upward synchronously. The upward force of the stabilizing rod 33 is transformed through the meshing action of the rotating rod 6 and the stabilizing rod 33. This transformation of the meshing action makes the upward movement of the stabilizing rod 33 stable.

[0038] In this invention, as a preferred embodiment, the top of the lifting platform 102 is provided with an angle adjustment plate 7. One end of the angle adjustment plate 7 is provided with a circular plate 71 that covers the floating rod 1. The floating rod 1 is movably disposed inside the circular plate 71. The other end of the angle adjustment plate 7 is provided with a worm gear 8. The worm gear 8 drives the angle adjustment plate 7 to swing around the floating rod 1 around the center. The floating rod 1 rotates as the angle adjustment plate 7 swings. The connecting plate 32 and the rotating rod 6 are both disposed on the angle adjustment plate 7.

[0039] In this invention, when the suction cup 11 picks up and transports the optical module, if it is necessary to adjust the angle of the suction cup 11, the worm gear 8 is opened, which drives the angle adjustment plate 7 to swing around the floating rod 1. The swing of the angle adjustment plate 7 drives the floating rod 1, the connecting plate 32, and the rotating rod 6 to swing in the overall direction. The angle swing of the floating rod 1 causes the suction angle of the suction cup 11 to change, thereby achieving the adjustment of the suction angle of the suction cup 11.

[0040] In this invention, as a preferred embodiment, the specific structure of the worm gear component 8 is as follows: the worm gear component 8 includes an arc gear 81 disposed at the end of the angle adjustment plate 7, a drive motor 82, and a helical rod 83 disposed at the output end of the drive motor 82, wherein the helical rod 83 and the arc gear 81 are meshed and connected.

[0041] In this invention, the worm gear component 8 is powered by a drive motor 82, and through the meshing connection of the arc gear 81 and the helical rod 83, it drives the arc plate to swing.

[0042] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
