Description

Technical Field

[0001] This invention relates to the field of precision device packaging technology, and in particular to an automatic lens packaging device. Background Technology

[0002] Semiconductor lasers possess numerous advantages, including high efficiency, long lifespan, good beam quality, small size, light weight, and the ability to be fully solidified. In recent years, they have experienced rapid development and have become one of the most noteworthy research hotspots in the international laser field. High-power semiconductor lasers have broad application prospects and development potential in industrial processing, medicine, and military fields. Their technological level and research capabilities directly constrain the development of laser technology.

[0003] To further improve the output power of semiconductor lasers and expand their applications, multiple light-emitting chips and lenses are typically arranged together to form linear, planar, or stacked arrays. The light output from each chip and lens is then spatially combined and focused, coupled into an optical fiber to achieve high beam quality and high power output. Therefore, semiconductor lasers require a large number of lenses to be coupled and packaged within their housing.

[0004] As precision devices, semiconductor lasers have very small internal lenses, typically only about 1 millimeter in size. Therefore, during the coupling and packaging process, the lenses need to be neatly arranged to ensure work efficiency, allowing the coupling robot to accurately position the lenses. Ideally, the lens orientation should be initially accurate to reduce the adjustment steps of the coupling robot and improve the coupling success rate.

[0005] Lenses are discharged randomly after manufacturing and require specific processes and equipment to be arranged orderly into packaging boxes. Multiple boxes are then bagged (or boxed) for transportation. Subsequently, the lenses within the packaging boxes can be quickly and automatically placed into the material trays of the coupling and packaging equipment. Furthermore, lenses may have defects after manufacturing, necessitating the rejection of substandard lenses. Currently, no automated packaging equipment for microlenses has been found in the existing technology. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a device that can automatically complete lens packaging, so that the lenses are arranged in an orderly manner in the packaging box after manufacturing and output, facilitating rapid tray loading during subsequent coupling and packaging, and improving work efficiency.

[0007] To achieve the above objectives, the present invention provides an automatic lens packaging device, including a tray feeding assembly, a tray positioning assembly, a lens picking assembly, and a packaging box feeding and positioning assembly.

[0008] The tray feeding assembly is used to feed trays containing lenses sequentially, wherein the lenses in the trays are arranged randomly.

The rotating part of the tray positioning seat is connected to the tray angle adjustment mechanism, and the fixing part of the tray positioning seat is connected to the tray displacement mechanism.

[0016] Furthermore, the lens motion mechanism includes a lens translation mechanism and a lens rotation leveling mechanism. The lens translation mechanism has multiple translational degrees of freedom, and the lens rotation leveling mechanism is used to adjust the clamping level of the lens gripper.

[0017] Furthermore, the lens movement mechanism includes a lens flipping mechanism, which is used to flip the lens gripper by a preset angle.

[0018] Furthermore, the lens pickup assembly also includes a lens recognition assembly, which includes a detection sensor and a lens ejector mechanism;

[0019] The detection sensor confirms the position of the lens on the tray by distance detection;

[0020] The lens ejector mechanism includes an ejector displacement part and an ejector platform. The ejector displacement part is connected to the ejector platform and is used to drive the ejector platform to rise and fall.

[0021] Furthermore, the automatic lens packaging equipment also includes a surface inspection component, which includes a first surface inspection component and a second surface inspection component. Both the first surface inspection component and the second surface inspection component visually inspect and confirm surface defects of the lens.

[0022] Furthermore, the first surface inspection component is disposed above the tray positioning seat, and the first surface inspection component includes a first vision inspection camera, which is used to detect surface defects of the lens.

[0023] Furthermore, the second surface inspection component includes a second visual inspection camera and a lens transfer unit. The lens transfer unit includes a lens suction head and a suction head rotation motor that drives the lens suction head to rotate. The lens suction head adsorbs the lens by negative pressure. The second visual inspection camera is correspondingly arranged with the lens suction head and is used to detect surface defects of the lens.

[0024] Furthermore, the packaging box feeding and positioning assembly includes a packaging box feeding and positioning platform, on which multiple open packaging boxes are arranged. The packaging boxes are used to place lenses and arrange them in an orderly manner. The packaging box feeding and positioning platform is also provided with a top cover mechanism, which is used to lift the lid of the packaging box upwards, so that the lid flips around the hinge axis and closes.

[0025] It also includes a packaging box bagging assembly, which includes a packaging box transfer robot, a packaging box transfer conveyor line, and a bagging mechanism. The packaging box transfer conveyor line connects the packaging box loading and positioning platform to the bagging mechanism. The packaging box transfer robot is used to transport the packaging boxes covered on the packaging box loading and positioning platform to the packaging box transfer conveyor line. The bagging mechanism includes a packaging bag suction head and a packaging bag control unit. The packaging bag suction head is used to suction the surface of the packaging bag, and the packaging bag control unit is connected to the packaging bag suction head to control the displacement of the packaging bag suction head.

For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] like Figures 1-10 As shown, an embodiment of the present invention provides an automatic lens packaging device, including a tray feeding assembly 100, a tray positioning assembly 200, a lens pickup assembly 300, and a packaging box feeding and positioning assembly 400. The tray feeding assembly 100 uses a conveyor belt to sequentially feed trays 101 containing lenses 5. The lenses 5 in the trays 101 are initially arranged randomly and need to be arranged in an orderly manner later. The tray positioning assembly 200 includes a tray adjustment mechanism and a tray positioning seat 201 connected to the tray adjustment mechanism. The tray positioning seat 201 is used to position the trays 101 containing lenses 5. The tray adjustment mechanism is used to adjust the position and angle of the trays 101, so that the lenses 5 on the trays 101 are in a convenient position and angle for pickup. The lens picking assembly 300 includes a lens manipulator, which comprises a lens motion mechanism and a lens gripper 301 connected to the lens motion mechanism. The lens gripper 301 is used to hold lenses 5 to pick up lenses 5 from the tray 101 and transfer them to the packaging boxes 401 of the packaging box loading and positioning assembly 400, ensuring their orderly placement. Therefore, precise control by the lens motion mechanism is required. The packaging box loading and positioning assembly 400 is used to sequentially load opened packaging boxes 401 and simultaneously close the packaging boxes 401 after the lenses 5 have been loaded for further processing.

[0046] Therefore, the device provided in this embodiment can sequentially pick up and transfer the disordered lenses 5 on the tray 101 to the packaging box 401 and arrange them in an orderly manner, and then close the packaging box 401 to complete the automatic packaging of the lenses 5. Compared with manual operation, it improves the degree of automation and thus improves the work efficiency.

[0047] In this embodiment, the material tray 101 is in the form of a blue film tray, which is generally composed of a blue film and a blue film iron ring. The blue film is usually flexible and cannot achieve high-precision positioning of the lens 5 placed on it. Therefore, it needs to be picked up and transported by a lens robot or the like. The material tray loading assembly 100 includes a material tray conveyor belt 102, on which multiple material trays 101 are placed and transported sequentially, so that the material trays 101 are moved sequentially to one side of the material tray positioning assembly 200. Then, the material trays 101 are placed on the material tray positioning seat 201 by a handling mechanism or manual means, thereby completing the positioning of the material trays 101.

[0048] In this embodiment, the tray positioning assembly 200 further includes a base 202, and the tray positioning seat 201 includes a fixed part and a rotating part. The rotating part is used to place the tray 101, and is rotatably connected to the fixed part. The tray adjustment mechanism includes a tray displacement mechanism 203 and a tray angle adjustment mechanism. The tray angle adjustment mechanism includes an angle adjustment motor 204, the drive shaft of which is connected to a synchronous pulley 205. The synchronous pulley 205 is connected to the rotating part via a synchronous belt 206. The fixed part, angle adjustment motor 204, etc., are all mounted on the base 202, so the rotating part and the tray 101 can rotate relative to the base 202 to adjust their orientation angle. The base 202 is connected to the tray displacement mechanism 203, which has multiple translational degrees of freedom, specifically set to the X and Y directions in this embodiment. It can move the tray positioning seat 201 and the tray 101 to a preset position, facilitating the lens robot to pick up the tray at the preset position.

[0049] It should be noted that the material tray positioning seat 201 is ring-shaped and matches the circular material tray 101. It is placed on the rotating part (with a slot) of the material tray positioning seat 201. The bottom center of the material tray 101, i.e. the blue film tray, is in a suspended state to facilitate operation from below the blue film tray.

[0050] In this embodiment, the lens motion mechanism includes a lens translation mechanism 302 and a lens rotation and leveling mechanism 303. The lens translation mechanism 302 has multiple translational degrees of freedom, specifically X and Z in this embodiment. It should be noted that the Y-axis is not included because the tray positioning assembly 200 already has a Y-axis degree of freedom. Therefore, the position of the lens 5 to be picked up can be moved to the Y-coordinate position of the lens gripper 301, where the lens gripper 301 performs operations. The lens rotation and leveling mechanism 303 is connected to the lens translation mechanism 302 and has rotational degrees of freedom around the Z-axis and around the horizontal axis. It can adjust the orientation angle and levelness of the lens gripper 301, allowing it to pick up lenses 5 from different directions, adjust them to a preset orientation angle, and achieve a horizontal orientation, facilitating subsequent inspection and placement.

[0051] Meanwhile, the lens movement mechanism also includes a lens flipping mechanism 304, which is connected to the lens rotation and leveling mechanism 303. The lens flipping mechanism 304 is used to flip the lens gripper 301 by a preset angle, which is 90 degrees in this embodiment, so that the lens 5 can be further transferred, etc.

[0052] The lens gripper 301 includes a pair of gripper arms arranged opposite each other and a gripper cylinder that drives the gripper arms to open and close. The gripper cylinder, similar to a finger cylinder, controls the pair of gripper arms to close and clamp the lens 5, or to open and place the lens 5. The ends of the gripper arms are provided with slots, which are used to position the diagonally of the generally square lens 5, ensuring accurate positioning of the lens 5 after it is gripped by the lens gripper 301. In addition, the lens gripper 301 also includes a gripper translation mechanism, which drives the gripper arms to translate, giving the lens 5 a certain degree of translational adjustment capability after flipping.

[0053] Since the lenses 5 are randomly placed on the tray 101, to enable the lens robot to accurately identify and pick up the lenses 5 on the tray 101, the lens picking assembly 300 in this embodiment also includes a lens identification assembly, which specifically consists of a detection sensor and a lens feeding mechanism. The detection sensor is located below the tray positioning assembly 200 and confirms the position of the lens 5 on the tray 101 by distance detection. Since the blue film tray is made of transparent material, it can be detected optically. Simultaneously, based on the material properties of the blue film tray, there is a certain adhesive force between the blue film tray and the lens 5, which also facilitates the loading of the lens 5 onto the tray. Therefore, to enable the lens robot to pick up the lens 5 more smoothly, the lens feeding mechanism includes a feeding displacement part 305 and a feeding platform 306. The feeding displacement part 305 is connected to the feeding platform 306 and is used to drive the feeding platform 306 to rise and fall. The feeding displacement part 305 can be driven by a lead screw or a cam, etc., and no specific limitation is made here.

[0054] The detection sensor and the lens ejector mechanism are both fixedly installed. The position where the lens robot picks up the lens 5 is directly above the ejector platform 306. Therefore, when the tray 101 moves with the tray positioning component 200 in a certain pattern, a certain lens 5 on it will pass directly above the detection sensor and be identified by the detection sensor. As a result, the tray positioning component 200 stops the lens 5 from being directly above the ejector platform 306. The ejector displacement part 305 drives the ejector platform 306 to rise and contact the lower surface of the blue film tray. While deforming the blue film tray, the lens 5 at this position is pushed upward (by a small amount) to reduce the adhesion between the lens 5 and the blue film tray, making it easier for the lens robot to pick up.

[0055] Simultaneously, the orientation of lens 5 also needs to be further identified to ensure that the lens gripper 301 picks up lens 5 with accurate orientation and tilt. Based on this, a first visual inspection camera 601 is also provided, located above the lens gripper 301, to identify and confirm the orientation and tilt of lens 5 on the tray 101, facilitating accurate pickup of lens 5 after the lens gripper 301 adjusts its orientation. Of course, after the lens gripper 301 picks up lens 5, the orientation of lens 5 needs to be adjusted to be horizontal, and the orientation angle should be directly opposite, i.e., along the X direction, to facilitate subsequent inspection and placement.

[0056] It is understandable that lenses 5 will have surface defects after manufacturing, so these lenses 5 need to be rejected and not placed in the packaging box 401. Based on this, this embodiment also provides a surface inspection component, which consists of a first surface inspection component and a second surface inspection component. Both the first and second surface inspection components visually inspect and confirm the surface defects of the lenses 5, and can cooperate to inspect all six surfaces of the lenses 5.

[0057] In this embodiment, the first surface detection component is disposed above the tray positioning seat 201. The first surface detection component is the aforementioned first visual inspection camera 601, which can also detect surface defects of the lens 5. The second surface detection component includes a second visual inspection camera 602 and a lens transfer unit. The lens transfer unit includes a lens suction head 603 and a suction head rotation motor 604 that drives the lens suction head 603 to rotate. The lens suction head 603 adsorbs the lens 5 by negative pressure. The second visual inspection camera 602 is correspondingly disposed with the lens suction head 603. Driven by the suction head rotation motor 604, the lens suction head 603 rotates to align different surfaces of the lens 5 with the second visual inspection camera 602, allowing the second visual inspection camera 602 to detect whether there are defects on multiple surfaces of the lens 5.

[0058] Specifically, such as Figure 6 , Figure 7 As shown, the six surfaces of lens 5 are labeled A to F. When lens gripper 301 grips lens 5, its gripper arms contact surfaces B and D. At this time, surface F faces upward and surface E faces downward. The first visual inspection camera 601 detects whether surface F has a defect. Then, lens gripper 301 moves to be directly above the second visual inspection camera 602, which detects whether surface E has a defect. Subsequently, lens gripper 301 rotates 90 degrees and also flips 90 degrees, as shown. Figure 8 As shown, the lens 5 is moved to the position of the lens suction head 603, so that the F surface (or E surface) of the lens 5 is attracted by the lens suction head 603. The lens suction head 603 rotates so that the A to D surfaces of the lens 5 are aligned with the second vision inspection camera 602 below in sequence, completing the defect detection of the remaining four surfaces. At this point, the detection of all surface defects of the lens 5 is completed.

[0059] Once lens 5 is confirmed to be qualified, lens gripper 301 picks up lens 5 again from lens suction head 603, adjusts its posture (aligns it), and places it in the packaging box 401 of packaging box loading and positioning component 400, arranging them in an orderly manner. Packaging box loading and positioning component 400 includes packaging box loading and positioning platform 402, which is connected to loading platform moving mechanism 403. Multiple open packaging boxes 401 are loaded onto packaging box loading and positioning platform 402. The loading platform moving mechanism 403 moves each packaging box 401 sequentially to the Y-coordinate position of lens gripper 301, allowing for fine-tuning to ensure that lenses 5 are arranged in an orderly manner within packaging boxes 401. Meanwhile, the packaging box feeding and positioning platform 402 is also equipped with a top cover mechanism. The top cover mechanism is located under the lid of the open packaging box 401. After the packaging box 401 is filled, the top cover mechanism will lift one side of the lid upward, so that the lid will rotate 180 degrees around the hinge axis and close the packaging box 401. The sealing edge can be equipped with a magnetic structure to ensure that the lid is magnetically fixed and forms a stable closed state.

[0060] As a further improvement, this embodiment also includes a packaging box bagging assembly, which can further bag the packaging box 401. Specifically, the packaging box bagging assembly includes a packaging box transfer robot 404, a packaging box transfer conveyor line 405, and a bagging mechanism. The packaging box transfer conveyor line 405 is located between the packaging box loading and positioning table 402 and the bagging mechanism. The packaging box transfer robot 404 is used to transport the packaging box 401, which has been loaded and closed on the packaging box loading and positioning table 402, to the packaging box transfer conveyor line 405. The packaging box 401 moves with the packaging box transfer conveyor line 405 to the bagging mechanism and is dropped into the opened packaging bag 406.

[0061] The bagging mechanism includes a bag suction head 407 and a bag control unit 408. Two sets of bag suction heads 407 are arranged opposite each other, respectively for suctioning the two sides of the packaging bag 406. The bag control unit 408 is connected to the bag suction head 407 and is used to control the opening or closing of the bag suction heads 407 on both sides to open or close the opening of the packaging bag 406 (the inner surface is adhesive). In addition, the bag control unit 408 may also include a translation mechanism to drive the bag suction head 407 to translate as a whole, so that it can move from one side to the discharge position of the packaging box transfer conveyor line 405 after suctioning the packaging bag 406, and move to the discharge position of the packaging bag 406 after the packaging bag 406 is completed and closed.

[0062] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
