Description

Technical Field

[0001] This invention relates to the field of optical device technology, and more specifically, to an adsorption device, an optical coupling device, and a method of using the same. Background Technology

[0002] Optical coupling equipment is a device that assembles various optical components into products (such as lasers). Since most optical components are precision components and are extremely sensitive to contamination or physical damage, they are assembled by using a suction nozzle to pick up the optical components.

[0003] Generally, optical coupling devices have an adsorption device, which has a fixing device to fix multiple suction nozzles, making it easy to select the corresponding suction nozzle for different optical elements.

[0004] However, in existing technologies, the suction nozzle is usually locked in the fixing device by a simple physical snap-fit, and the suction nozzle cannot be actively released. When the suction device such as the robotic arm removes the suction nozzle, it is easy for the suction nozzle to rub against the fixing device, which may cause the suction nozzle to fall or be damaged. Summary of the Invention

[0005] This application addresses the shortcomings of existing methods by proposing an adsorption device, an optical coupling device, and a method for using the same, in order to solve the technical problems existing in related technologies, such as the suction nozzle being stuck in a fixed device by a simple physical locking method and unable to be actively released.

The spacing between adjacent release notches is the same as the spacing between the release notches and the suction nozzles. In the fixed state, the sidewalls of a set of positioning shafts are embedded in the grooves on both sides of the corresponding column of nozzles, blocking the nozzles in the removal direction; in the released state, the release notch of a set of positioning shafts is directly opposite the corresponding column of nozzles, so that there is no obstruction area of ​​the positioning shafts in the removal direction of the corresponding column of nozzles.

[0011] In some embodiments, the moving component further includes: A guide shaft is arranged parallel to the positioning shaft; the guide shaft passes through a limiting member on the second fixed plate; The connector connects the positioning shaft and the guide shaft, and is movablely connected to the drive mechanism.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0029] This application provides an adsorption device 100, the structural schematic diagram of which is shown below. Figures 1-4 As shown, the adsorption device 100 includes: a base 10, multiple sensors 20, a first fixing plate 30, multiple suction nozzles 40, and a limiting component 50.

[0030] Multiple sensors are arranged in an array of 20.

[0031] The first fixing plate 30 is connected to the base 10, and the first fixing plate 30 is used to fix multiple sensors 20.

[0032] Multiple suction nozzles 40 are positioned one-to-one above multiple sensors 20, and are designed to be removed in the released state; the removal direction is the direction in which the suction nozzle 40 moves away from the sensor 20. One suction nozzle 40 corresponds to one sensor 20.

[0033] The limiting component 50 is used to fix the suction nozzle 40 in the fixed state and block the suction nozzle 40 in the extraction direction, and to carry the suction nozzle 40 in the released state, and to have no obstruction area in the extraction direction of at least one suction nozzle 40.

[0034] In this embodiment, the adsorption device 100 has a limiting component 50, which can switch between a fixed state and a released state to respectively achieve the fixing function of blocking the suction nozzle 40 in the extraction direction and the active release function of not obstructing in the extraction direction. This can avoid the risk of damage or falling of the suction nozzle 40 caused by forced extraction and ensure the service life of the suction nozzle 40.

[0035] Moreover, in the released state, the suction device does not require a complicated "pull" action, and can achieve "resistance-free" suction, which can improve the success rate and efficiency of suction, and improve the stability of equipment operation.

[0036] In addition, this embodiment obtains the presence status of the suction nozzle 40 through the sensor 20 located below the suction nozzle 40, and then performs dynamic storage operation, which facilitates the management of the suction nozzle 40 of the adsorption device 100, avoids invalid suction operation due to the absence of the suction nozzle 40, avoids waste of resources, and can also verify the accuracy of suctioning or putting back the suction nozzle 40.

[0037] Furthermore, this application provides two different embodiments of the adsorption device 100, which will be described in detail below with reference to the accompanying drawings.

[0038] Figure 1 and Figure 2 This is a schematic diagram of the adsorption device 100 according to the first embodiment. In the first embodiment, the limiting component 50 includes: a second fixing plate 53 and a moving component.

[0039] The second fixing plate 53 is disposed above the first fixing plate 30 and is fixedly connected to the base 10; the second fixing plate 53 fixes the suction nozzle 40. The peripheral surface of the suction nozzle 40 has a groove 44.

[0040] The movable component is movably connected to the base 10; the movable component is partially disposed on the side of the nozzle 40, and the side of the movable component facing the nozzle 40 has at least one release notch 550.

[0041] In the fixed state, the movable component is partially embedded in the groove 44, blocking the nozzle 40 in the removal direction; in the released state, the release notch 550 faces the groove 44, and the movable component is in an unobstructed area in the removal direction of at least one nozzle 40.

[0042] Please refer to Figure 1 and Figure 2 , Figure 1 This is a structural diagram from an overall perspective. Figure 2 This is a magnified view of a portion of the image. In this embodiment, by controlling the relative movement between the moving component with the release notch 550 and the suction nozzle 40 with the groove 44, in the fixed state, the moving component and the suction nozzle 40 physically interfere with each other, preventing the suction nozzle 40 from being removed in the extraction direction. In the released state, the physical interference between the moving component and the suction nozzle 40 is released, allowing the suction nozzle 40 to be freely extracted. This embodiment employs physical limiting, which improves the reliability of the limiting mechanism. Furthermore, the fixed or released states are intuitively visible, facilitating direct observation by the operator and enabling operation based on the observation. It exhibits high versatility and fault tolerance under manual operation.

[0043] In some possible embodiments of the first implementation, the second fixing plate 53 has a plurality of first through holes 531.

[0044] The suction nozzle 40 includes a connected middle part 41 and a head 42. The outer diameter of the middle part 41 is smaller than the outer diameter of the head 42. The middle parts 41 of the multiple suction nozzles 40 are inserted into the multiple first through holes 531 in a one-to-one correspondence. The outer diameter of the head 42 is larger than the inner diameter of the first through hole 531, so that the head 42 overlaps the second fixing plate 53.

[0045] Please refer to Figure 1 and Figure 2 It is understandable. Figure 2 The third suction nozzle 40 from the top in the first column is hidden, making the first through hole 531 visible. In actual use, the head 42 of this suction nozzle 40 covers the first through hole 531, making the first through hole 531 visible. Figure 2 It is not visible from the field of view. In this embodiment, the suction nozzle 40 is a multi-segment design, in which the middle part 41 is thinner and the head 42 is thicker, so that the middle part 41 passes through the first through hole 531, while the head 42 cannot pass through the first through hole 531 and can be placed on the second fixing plate 53. It is fixed under the action of gravity, which effectively prevents the suction nozzle 40 from coming out of the first through hole 531, ensuring the reliable fixation of the suction nozzle 40 in the vertical direction and avoiding displacement or falling off due to vibration or accidental contact.

[0046] In some possible embodiments of the first implementation, the moving component includes a drive mechanism 54 and a positioning shaft 55.

[0047] The drive mechanism 54 is fixed to the base 10.

[0048] The positioning shaft 55 is movably connected to the drive mechanism 54, parallel to the arrangement direction of the nozzle 40 and located on the side of the nozzle 40; the release notch 550 is located on the side of the positioning shaft 55 facing the nozzle 40.

[0049] In the fixed state, the positioning shaft 55 is partially embedded in the groove 44, blocking the nozzle 40 in the removal direction; in the released state, the release notch 550 faces the groove 44, and the positioning shaft 55 has no obstruction area in the removal direction of at least one nozzle 40.

[0050] Please refer to Figure 1 and Figure 2 It is understandable. Figure 2 The leftmost positioning shaft 55 and the third suction nozzle 40 from the top in the first column are hidden, so that the release notch 550 of the positioning shaft 55 and the groove 44 of the suction nozzle 40 are exposed, making it easier for the reader to understand.

[0051] In this embodiment, the drive mechanism 54 is fixed relative to the base 10. The drive mechanism 54 drives the positioning shaft 55 to move. By controlling the relative movement between the positioning shaft 55, which has a release notch 550, and the suction nozzle 40, which has a groove 44, the positioning shaft 55 and the suction nozzle 40 physically interfere with each other in the fixed state, preventing the suction nozzle 40 from being removed in the removal direction. In the released state, the physical interference between the positioning shaft 55 and the suction nozzle 40 is released, allowing the suction nozzle 40 to be freely sucked up. This embodiment of the application uses a simple movable positioning shaft 55 to physically limit the suction nozzle 40, which can improve the reliability of the limiting, and has a simple structure and is easy to operate.

[0052] Moreover, in this embodiment, the positioning shaft 55 is displaced by the drive mechanism 54, the components are mature, and the cost is controllable.

[0053] Alternatively, the drive mechanism 54 can be a cylinder.

[0054] Optionally, the top side of the base 10 has outwardly extending wings 11, and the drive mechanism 54 is fixed above the wings 11, so that the drive mechanism 54 is fixedly connected to the base 10.

[0055] Optionally, the drive mechanism 54 includes a fixed cylinder 541 and a retractable piston assembly 542. The cylinder 541 is fixed relative to the seat 10. The connector 57 is connected to the retractable piston assembly 542 and is also fixedly connected to multiple positioning shafts 55, thereby realizing the movable connection between the drive mechanism 54 and the positioning shafts 55.

[0056] In some possible embodiments of the first implementation, a plurality of suction nozzles 40 are arranged in an array; there are a plurality of positioning shafts 55, which are arranged side by side along the row direction of the suction nozzles 40; the axial direction of the positioning shafts 55 is parallel to the column direction of the suction nozzles 40.

[0057] Two adjacent positioning axes 55 form a set of positioning axes 55, and the set of positioning axes 55 are located on both sides of a row of suction nozzles 40.

[0058] In a set of positioning shafts 55, the release notches 550 of each positioning shaft 55 are opposite each other, and the number of release notches 550 is the same as the number of suction nozzles 40. The spacing between adjacent release notches 550 is the same as the spacing between suction nozzles 40.

[0059] In the fixed state, the sidewalls of a set of positioning shafts 55 are embedded in the grooves 44 on both sides of the corresponding row of suction nozzles 40, blocking the suction nozzles 40 in the removal direction; in the released state, the release notches 550 of the set of positioning shafts 55 are directly opposite the corresponding row of suction nozzles 40, so that there is no obstruction area of ​​the positioning shafts 55 in the removal direction of the corresponding row of suction nozzles 40 in the removal direction.

[0060] In this embodiment, each set of positioning axes 55 is symmetrically arranged, which can simultaneously limit the opposite sides of the suction nozzle 40, improve the reliability of fixation, and avoid the problem of the suction nozzle 40 tilting due to unilateral limiting.

[0061] Furthermore, the spacing between adjacent release notches 550 of the positioning shaft 55 is the same as the spacing between the nozzles 40, which enables synchronous fixing or releasing operations for a group of nozzles 40, thereby improving release efficiency.

[0062] It is understandable that the array of nozzles 40 has two arrangement directions: row direction and column direction. Each row of nozzles 40 can be set as a group of nozzles 40, and a set of positioning axes 55 are located on both sides of the group of nozzles 40 to limit the movement of the group of nozzles 40.

[0063] In some possible embodiments of the first implementation, the limiting component 50 further includes a guide shaft 56 and at least one connector 57.

[0064] The guide shaft 56 is arranged parallel to the positioning shaft 55; the guide shaft 56 passes through the limiting member 530 on the second fixing plate 53.

[0065] Connector 57 connects positioning shaft 55 and guide shaft 56, and is movably connected to drive mechanism 54.

[0066] In this embodiment, the guide shaft 56 and the positioning shaft 55 are synchronously displaced through the connecting member 57. The guide shaft 56 passes through the limiting member 530, which can limit the movement direction of the guide shaft 56, thereby limiting the movement direction of the positioning shaft 55. This can prevent the positioning shaft 55 from moving in the wrong direction, thus avoiding the problem of the positioning shaft 55 colliding with the suction nozzle 40.

[0067] Next, we will introduce the second implementation method.

[0068] Figure 3 and Figure 4 This is a schematic diagram of the adsorption device 100 according to the second embodiment. In the second embodiment, the limiting component 50 includes a third fixing plate 51.

[0069] The third fixing plate 51 is disposed above the first fixing plate 30 and is rotatably connected to the base 10; the third fixing plate 51 has a plurality of second through holes 511.

[0070] The suction nozzle 40 includes a connected middle part 41 and a head 42, the outer diameter of the middle part 41 is smaller than the outer diameter of the head 42; the middle parts 41 of the multiple suction nozzles 40 are inserted into the multiple second through holes 511 in a one-to-one correspondence; when the third fixing plate 51 is upright, the head 42 overlaps on the third fixing plate 51; when the third fixing plate 51 is inverted, the head 42 is magnetically connected to the third fixing plate 51.

[0071] In the fixed state, the third fixing plate 51 is in an inverted state, blocking the nozzle 40 in the extraction direction; in the released state, the third fixing plate 51 is in an upright state, and the head 42 of the nozzle 40 is located above the third fixing plate 51 in the extraction direction, so that the third fixing plate 51 has no obstruction area in the extraction direction of at least one nozzle 40.

[0072] Please refer to Figure 3 and Figure 4 , Figure 3 The image shows the adsorption device 100 in a fixed state, with the third fixing plate 51 in an inverted state. Figure 4 The adsorption device is shown in the released state, with the third fixing plate 51 in the upright position.

[0073] In this embodiment, the third fixing plate 51, which is rotatably connected to the base 10, can be flipped to an upright or inverted state. By changing the blocking state of the third fixing plate 51 on the suction nozzle 40 through the flippable third fixing plate 51, the switching between the fixed state and the release state can be realized. The structure is simple, and there is no relative mechanical movement between the suction nozzle 40 and the third fixing plate 51 during the fixing and release process, which can reduce the possibility of friction between the suction nozzle 40 and the third fixing plate 51.

[0074] Specifically, the suction nozzle 40 includes a head 42, a middle portion 41, and a tail 43 connected together. The outer diameters of the head 42, middle portion 41, and tail 43 decrease sequentially. The middle portion 41 of the suction nozzle 40 is at least partially located within the second through hole 511. In the fixed state, the third fixing plate 51 is inverted, and the head 42 with a larger outer diameter is fixed to the third fixing plate 51 under the action of magnetic force, preventing the suction nozzle 40 from falling off. Furthermore, along the removal direction, the inner diameter of the second through hole 511 of the third fixing plate 51 is smaller than the outer diameter of the head 42 of the suction nozzle 40, so that the third fixing plate 51 acts as a blockage, preventing the suction nozzle 40 from being accidentally removed.

[0075] In the released state, the third fixing plate 51 is flipped so that the head 42 of the suction nozzle 40 is above the third fixing plate 51, that is, the head 42 can be placed on the third fixing plate 51 under the action of gravity, so that the suction nozzle 40 can be taken out directly without obstruction in the removal direction.

[0076] Optionally, the third fixing plate 51 and the base 10 can be rotatably connected by providing a shaft hole in the base 10 and a rotating shaft on the third fixing plate 51, and inserting the rotating shaft into the shaft hole.

[0077] In some possible embodiments of the second implementation, the distance between the first fixing plate 30 and the third fixing plate 51 along the axial direction of the nozzle 40 is greater than the length of the head 42 but not greater than the length of the nozzle 40.

[0078] In this embodiment, along the axial direction of the nozzle 40, the distance between the first fixing plate 30 and the third fixing plate 51 is greater than the length of the head 42 but not greater than the length of the nozzle 40. This ensures that there is sufficient space between the first fixing plate 30 and the third fixing plate 51 to accommodate the head 42 of the nozzle 40 when the third fixing plate 51 is inverted, preventing the head 42 from colliding with the sensor 20 due to insufficient space. It also ensures that the space between the first fixing plate 30 and the third fixing plate 51 is not large enough to accommodate the entire nozzle 40, thus preventing the nozzle 40 from accidentally falling and being lost.

[0079] In some possible embodiments of the second implementation, please refer to Figures 3-4 The limiting component 50 also includes an electromagnetic coil 52.

[0080] The electromagnetic coil 52 is embedded in the third fixing plate 51.

[0081] The head 42 has magnetic force.

[0082] In the released state, the electromagnetic coil 52 is energized, so that the electromagnetic coil 52 has magnetic force.

[0083] In this embodiment, a gentle and controllable release operation is achieved through an energized electromagnetic coil 52. Specifically, the magnitude and polarity of the magnetic force are controlled by adjusting the magnitude, direction, and duration of the energized current. By controlling the energization of the electromagnetic coil 52, the repulsive force generated by the electromagnetic coil 52 on the suction nozzle 40 is controlled, ensuring that the like poles of the electromagnetic coil 52 and the suction nozzle 40 repel each other. This makes the suction nozzle 40 easier to remove, and the removal process is gentle, controllable, and user-friendly to the suction nozzle 40.

[0084] Furthermore, the magnetic poles of the electromagnetic coil 52 can be controlled to be opposite to those of the suction nozzle 40, thereby generating a suction force on the suction nozzle 40 that does not need to be removed, further securing the suction nozzle 40 that does not need to be removed.

[0085] Optionally, the head 42 of the nozzle 40 has a built-in magnet, so that the head 42 of the nozzle 40 has a magnetic force.

[0086] Alternatively, the third fixing plate 51 may be made of metal and be magnetically connected to the nozzle 40.

[0087] Optionally, the third fixing plate 51 is made of insulating material, and a metal block is provided on the surface of the third fixing plate 51 that contacts the head 42. The head 42 is magnetically connected to the metal block, thereby connecting the head 42 to the third fixing plate 51.

[0088] In some possible embodiments of the second implementation, please refer to Figures 3-4 There are multiple electromagnetic coils 52, each embedded in the inner wall of the second through hole 511.

[0089] Multiple electromagnetic coils 52 are connected in parallel or in series.

[0090] In this embodiment, each second through hole 511 is equipped with an electromagnetic coil 52. By setting at least two electromagnetic coils 52 in parallel or series connection, the suction nozzles 40 corresponding to at least two electromagnetic coils 52 can be released or fixed.

[0091] For example, all the electromagnetic coils 52 are connected in parallel, allowing each electromagnetic coil 52 to be controlled individually. Depending on actual needs, the electromagnetic coil 52 corresponding to the nozzle 40 that needs to be removed can be energized to generate a repulsive force, while a switch can be installed on the circuit of the electromagnetic coil 52 corresponding to the nozzle 40 that does not need to be removed to cut off the current. Alternatively, other electronic components can be added to the electromagnetic coil 52 corresponding to the nozzle 40 that does not need to be removed to give it an attractive force, thereby attracting and securing the nozzle 40. Individual control of the electromagnetic coil 52 enables the independent and selective release of a single nozzle 40, facilitating intelligent management in conjunction with the sensor 20.

[0092] For example, all electromagnetic coils 52 can be grouped, with at least two electromagnetic coils 52 forming a group. The electromagnetic coils 52 within a group are connected in series, so that the polarity change of a group of electromagnetic coils 52 can be controlled simultaneously, thereby controlling the nozzle 40 corresponding to a group of electromagnetic coils 52 to be fixed or released simultaneously, which can save on electrical control costs.

[0093] In some possible embodiments of the second implementation, the number of electromagnetic coils 52 is at least one, and each electromagnetic coil 52 is wound around at least two second through holes 511.

[0094] Unlike the previous embodiment, in this embodiment, each electromagnetic coil 52 covers the range of multiple second through holes 511, thereby enabling the control of one electromagnetic coil 52 to control the fixing or releasing of multiple suction nozzles 40, which can save the installation cost of electromagnetic coil 52.

[0095] In some possible embodiments of the second implementation, a plurality of electromagnetic coils 52 are connected in parallel, at least one electromagnetic coil 52 has the same magnetic pole as the head 42 when energized, and at least one electromagnetic coil 52 has the opposite magnetic pole to the head 42 when energized.

[0096] In this embodiment, by connecting multiple electromagnetic coils 52 in parallel and controlling each electromagnetic coil 52 individually, the electromagnetic coil 52 corresponding to the suction nozzle 40 that needs to be sucked will generate a repulsive force, while the electromagnetic coil 52 that does not need to be sucked will generate an attractive force. This effectively avoids the risk of mis-sucking or missing in a multi-target environment and greatly improves the accuracy and reliability of the suction operation.

[0097] Based on the same inventive concept, this application provides an optical coupling device, including: a moving module, a tray for holding optical elements, and an adsorption device 100 as provided in any of the above embodiments.

[0098] The moving module is used to remove the suction nozzle 40 of the adsorption device 100 and move it above the material tray so that the suction nozzle 40 can pick up the optical element.

[0099] In this embodiment, the adsorption device 100 provided in any of the above embodiments is used, and its implementation principle is similar, so it will not be described again here. The adsorption device 100 in this embodiment can switch between a fixed state and a released state through the limiting component 50, so as to respectively achieve the fixing function of blocking the suction nozzle 40 in the extraction direction and the active release function without obstruction in the extraction direction, which can avoid the risk of damage or falling of the suction nozzle 40 caused by forced suction and ensure the service life of the suction nozzle 40.

[0100] Based on the same inventive concept, this application provides a method for using an optical coupling device, the structural schematic diagram of which is shown below. Figure 5 As shown, the method includes steps S1-S7: S1: Move the moving module to the target position above the adsorption device 100; the suction nozzle 40 placed at the target position is the suction nozzle 40 to be removed.

[0101] S2: When the nozzle 40 is present at the target position, the target position of the adsorption device 100 is controlled to be in a release state.

[0102] S3: The lowering of the moving module causes the moving module to suck up the nozzle 40.

[0103] S4: Move the mobile module with suction nozzle 40 above the target position.

[0104] S5: The target position of the adsorption device 100 is in a release state.

[0105] S6: If there is no suction nozzle 40 at the target position, the moving module is lowered so that the suction nozzle 40 sucked up by the moving module is placed at the target position.

[0106] S7: The target position of the adsorption device 100 is kept in a fixed state.

[0107] In this embodiment, the method includes a method for picking up the suction nozzle 40 and a method for returning the suction nozzle 40. In the method for picking up the suction nozzle 40, the moving module can move within space. When a suction nozzle 40 needs to be removed, a sensor confirms that the suction nozzle 40 is located at the target position. Then, the moving module moves to the target position where the suction nozzle 40 is to be removed and descends until it picks up the suction nozzle 40. In the method for returning the suction nozzle 40, the moving module picks up the suction nozzle 40 to the target position. When it is confirmed that the target position is in a released state and the target position is vacant, the moving module descends and places the suction nozzle 40 back at the target position. This embodiment achieves precise picking up and placing of the suction nozzle 40 through position confirmation and release state detection, avoiding equipment collisions or damage to the suction nozzle 40 caused by positional deviations or target occupancy. This effectively improves the automation level and operational reliability of the equipment, reduces the need for manual intervention, and improves overall work efficiency.
