Description

Technical Field

[0001] This invention relates to an automated drying device for mobile phone camera lenses. Background Technology

[0002] In the production process of mobile phone camera lenses, the lens drying stage has a crucial impact on product quality. Traditional drying methods rely heavily on manual operation, where trays containing lenses are placed one by one into the drying oven, and then manually removed after drying. This method is not only labor-intensive and costly, but also poses a risk of burns due to direct contact between operators and the high-temperature environment inside the oven. Furthermore, manual operation suffers from poor consistency; parameters such as the placement of trays within the oven and drying time are difficult to control precisely, easily leading to uneven lens drying. In addition, manual loading and unloading are inefficient and cannot meet the high-speed, continuous production demands of modern production lines, thus hindering overall production efficiency improvements. Therefore, developing an automated drying device that enables automated loading and unloading, precise control of the drying process, and improved production efficiency and drying quality has become an urgent problem to be solved in the mobile phone camera lens manufacturing industry.

Detailed Implementation

[0016] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1 like Figure 1-6 As shown, this embodiment mainly includes a frame 100, a horizontal worktable 102, a first material handling robot 302, a second material handling robot 502, a drying device 400, a transfer mechanism 600, and a buffer mechanism 800.

[0018] The frame 100 serves as the supporting structure for the entire device. The horizontal worktable 102 is fixedly mounted on the frame 100, providing a mounting base for other functional components. The outer casing (not shown separately in the figure) is mounted on the frame 100, forming the external outline of the equipment.

[0019] The first material handling robot 302 and the second material handling robot 502 are preferably multi-joint robots or Cartesian coordinate robots, respectively set near the feeding area and the discharging area of ​​the horizontal worktable 102, and are used to perform the gripping, moving and placing actions of the material tray.

[0020] The drying device 400 is the core functional unit, forming a closed drying space through the first housing 404. A heating device 406, such as a heating tube or infrared heater, is installed within this drying space to provide the heat required for drying. An inlet / outlet 405 is provided on the first side plate of the first housing 404 as a channel for material exchange. To reduce heat loss, a baffle assembly 410 is installed at the inlet / outlet 405. This baffle assembly 410 includes a first baffle 414, which can be driven by a cylinder or motor (not shown) to move vertically relative to the inlet / outlet 405, thereby opening or closing the inlet / outlet 405.

[0021] The transfer mechanism 600 is mounted on the horizontal worktable 102. Its core function is to receive the material tray from the first material handling robot 302, accurately feed it into the drying device 400, and remove it after drying. The transfer mechanism 600 mainly includes a transfer platform 602 and a platform transfer mechanism.

[0022] The transfer platform 602 is the component that directly supports the material tray. The platform transfer mechanism is a complex three-dimensional motion system, which includes: The material lifting mechanism 604 is used to drive the transfer platform 602 to perform lifting movements to adjust its height. Its specific components include: a fixed base 608 fixedly mounted on the frame 100; a drive shaft 610 vertically mounted on the fixed base 608 and having external threads, one end of which is connected to the output shaft of a drive motor (not shown); a fixed mounting plate 612 positioned directly above the fixed base 608 and fixed thereto by a second connecting rod 618; and a movable lifting plate 614 located between the fixed base 608 and the fixed mounting plate 612, on which a drive nut threadedly connected to the drive shaft 610 is fixed. The movable lifting plate 614 is connected to the upper transfer platform 602 via a first connecting rod 616. When the drive shaft 610 rotates, it drives the movable lifting plate 614 to rise and fall via the threaded pair, thereby synchronously raising and lowering the transfer platform 602 via the first connecting rod 616. The second connecting rod 618 passes through the hole on the movable lifting plate 614 and forms a sliding fit with it, playing a guiding and stabilizing role.

[0023] First horizontal pushing mechanism 606: used to drive the transfer platform 602 along the first horizontal direction ( Figure 1 It can be considered as moving in the forward and backward direction to perform reciprocating linear motion. It includes a first linear guide rail 627 arranged along a first horizontal direction and a first drive device (such as a cylinder or linear motor) as power. The fixed mounting plate 612 is slidably mounted on the first linear guide rail 627 via a first slider 628.

[0024] The second horizontal feeding mechanism 607 is mounted on the transfer platform 602 and is used to drive the material tray to reciprocate linearly along the second horizontal direction. It includes a second linear guide rail 624 arranged along the second horizontal direction and a second driving device (such as a cylinder or linear motor).

[0025] Two buffer mechanisms 800 are provided, one located between the feeding area and the transfer mechanism 600, and the other between the transfer mechanism 600 and the discharge area. The buffer mechanisms 800 are used for temporary storage of material trays to balance production cycle time. Both buffer mechanisms 800 have the same structure, including an accumulating mechanism 802, a buffer platform 804, and a buffer drive mechanism 806. The buffer mechanism 800 on the feeding side is used for buffering material trays awaiting drying, while the buffer mechanism 800 on the discharge side is used for buffering dried material trays.

[0026] The buffer mechanism 800 includes a material accumulating mechanism 802, a buffer platform 804, and a buffer drive mechanism 806. The material accumulating mechanism 802 has multiple vertically arranged material accumulating slots. Each material tray can be placed on a flat support plate and then inserted entirely into the material accumulating slot to achieve three-dimensional buffering. The buffer platform 804 is provided with a slide rail that can dock with any material accumulating slot of the material accumulating mechanism 802. The buffer drive mechanism 806 is a horizontally arranged cylinder used in this embodiment. Its cylinder arm has a vertically extending block at its front end, which can be used to push the support plate, causing the material tray to slide horizontally between the material accumulating slot and the slide rail of the buffer platform 804.

[0027] The working process of the device is briefly described as follows: After the first picking robot 302 picks up the material from the feeding area, it places it directly onto the transfer platform 602 or stores it in the buffer mechanism 800, depending on the situation. The transfer mechanism 600 uses three-dimensional motion to precisely align the material tray and sends it into the drying device 400 for drying through the inlet / outlet 405. After drying, the transfer mechanism 600 removes the material tray, and then the second picking robot 502 transfers it to the discharge area or temporarily stores it in the buffer mechanism 800 on the discharge side. The entire process is automated, efficient, and continuous.

[0028] Example 2 Based on Example 1, this embodiment further optimizes the structure of the drying device 400 and the transfer mechanism 600 to improve space utilization and processing capacity.

[0029] In this embodiment, the drying device 400 is internally equipped with a material-carrying mechanism 408 and a drying lifting mechanism. The material-carrying mechanism 408 adopts a multi-layer frame 418 structure, which has multiple slots evenly spaced in the vertical direction, and can simultaneously accommodate multiple material trays, significantly improving the throughput of a single processing cycle. The drying lifting mechanism uses a screw lifting drive mechanism 420 to drive the multi-layer frame 418 to rise and fall, so that the slots of different layers can be aligned with the inlet and outlet ports 405.

[0030] The specific structure of the spiral lifting drive mechanism 420 includes: a base 422; a drive motor (not shown in the figure) mounted on the base 422 and a screw 424 driven by the drive motor; a lifting platform 426 threadedly engaged with the screw 424; a plurality of connecting rods 428, the two ends of which are respectively connected to the bottom of the lifting platform 426 and the multi-layer frame 418; an intermediate plate 430 located directly above the lifting platform 426, the top end of the screw 424 passing through the lifting platform 426 and rotatably connected to the intermediate plate 430; and at least two vertically arranged guide posts 432, the two ends of which are fixedly connected to the base 422 and the intermediate plate 430 respectively, and the guide posts 432 pass through a through hole on the lifting platform 426, forming a sliding engagement with the through hole to provide precise guidance for the lifting movement.

[0031] The structure of the baffle assembly 410 is also more complete, including two baffle columns 416 vertically arranged on both sides of the inlet and outlet 405, and a first baffle 414 slidably connected to the two baffle columns 416. A first driving device (such as a motor with a synchronous belt) is used to drive the first baffle 414 to move up and down synchronously along the baffle columns 416.

[0032] The transfer platform 602 is also designed to handle multiple trays simultaneously. It includes a fixed transfer base 620 and a transfer movable plate 622 slidably mounted on the transfer base 620 along a second horizontal direction. The transfer movable plate 622 has at least two feeding areas for placing trays along the second horizontal direction. A second horizontal pushing mechanism 607 drives the transfer movable plate 622 to move in the second horizontal direction, thereby aligning the different feeding areas with the pushing station.

[0033] This embodiment achieves efficient utilization of the drying space and flexible material flow through the cooperation of the multi-layer frame 418 and the movable multi-working conveying platform 602, making it particularly suitable for large-scale continuous production scenarios.

[0034] Example 3 This embodiment aims to provide a more detailed description of the transfer mechanism 600 mentioned in the above embodiments. The transfer mechanism 600 is the core component for achieving precise transfer of the material tray between the feeding position, drying position, and discharging position. Its key technology lies in achieving precise three-dimensional positioning of the material tray through the compound motion of three motion units. This mechanism is mainly composed of a material lifting mechanism 604, a first horizontal pushing mechanism 606, and a second horizontal pushing mechanism 607 working together.

[0035] The material conveying lifting mechanism 604 is responsible for the precise vertical (Z-axis) positioning of the conveying platform 602. Its structural foundation is a fixed base 608 firmly mounted on the frame 100. A drive shaft 610 with precision external threads is vertically mounted on the fixed base 608 via bearings. The lower end of the drive shaft 610 is connected to the output shaft of a servo motor via a coupling. Directly above the fixed base 608, a fixed mounting plate 612 is fixedly connected via at least two second connecting rods 618, ensuring that the height of the fixed mounting plate 612 remains constant. Between the fixed base 608 and the fixed mounting plate 612, a movable lifting plate 614 is provided, on which a drive nut that threadedly mates with the drive shaft 610 is fixedly mounted. When the servo motor drives the drive shaft 610 to rotate, the drive nut, through the threaded transmission, drives the movable lifting plate 614 to move linearly up and down along the axial direction of the drive shaft 610. The second connecting rod 618 passes through a corresponding aperture on the movable lifting plate 614, forming a sliding fit, thereby guiding the movement of the movable lifting plate and preventing its rotation. The movable lifting plate 614 is connected to the upper transfer platform 602 via at least two first connecting rods 616. Therefore, the rotational motion of the drive shaft 610 is ultimately converted into the linear lifting motion of the movable lifting plate 614, and the first connecting rods 616 drive the entire transfer platform 602 to precisely lift and lower, adapting to slots of different heights within the drying device 400.

[0036] The first horizontal pushing mechanism 606 drives the transfer platform 602 to move along the first horizontal direction (Y-axis, i.e., the direction towards or away from the drying device 400). The core components of this mechanism include a first linear guide rail 627 fixed along the Y-axis to the horizontal worktable 102 or frame 100, and a matching first slider 628. The first slider 628 is fixedly mounted on the bottom of the aforementioned fixed mounting plate 612, allowing the entire fixed mounting plate 612 and its supported components to slide along the Y-axis. The power source of the first horizontal pushing mechanism 606, such as a servo electric cylinder or pneumatic cylinder, has its cylinder body fixed to the fixed mounting plate 612, while its push rod acts on a fixed point (or is connected to the base of the transfer platform 602), thereby providing the power to push the entire transfer platform 602 assembly forward or backward along the Y-axis. This movement ensures that the transfer platform 602 can be accurately moved to a position aligned with the inlet / outlet 405 of the drying device 400.

[0037] The second horizontal pushing mechanism 607 is directly responsible for driving the material tray to move along the second horizontal direction (X-axis, perpendicular to the Y-axis, i.e., the direction in which the material tray extends into or exits the inlet / outlet 405). This mechanism is closely related to the intricate structure of the transfer platform 602. The transfer platform 602 itself is not a single unit; it consists of a transfer base 620 fixed to the top of the first connecting rod 616 and a transfer movable plate 622 mounted on the transfer base 620 via a linear guide pair. The transfer movable plate 622 can slide relative to the transfer base 620 along the X-axis direction and has at least two feeding areas for placing the material tray. The second horizontal pushing mechanism 607 includes a second linear guide 624 fixed along the X-axis direction on the transfer base 620 and a cooperating second slider 626, which is fixed to the bottom of the transfer movable plate 622. Its power source, such as another servo electric cylinder or pneumatic cylinder, has its cylinder body fixed on the transfer base 620, and the push rod is connected to the transfer movable plate 622. When the drive device is activated, it will drive the transfer movable plate 622 and all the material trays it carries to move together along the X-axis, thereby completing the final action of pushing the material trays into or removing them from the drying device.

[0038] During operation, these three mechanisms work in strict sequence. For example, when the material tray needs to be fed into the drying device, the material conveying lifting mechanism 604 first adjusts the conveying platform 602 to the target height; then, the first horizontal pushing mechanism 606 drives the platform forward along the Y-axis, aligning the material tray on it with the inlet and outlet; finally, the second horizontal pushing mechanism 607 actuates, pushing the material transfer movable plate 622 along the X-axis to smoothly deliver the material tray into the drying device. This hierarchical motion control ensures the accuracy and reliability of the transfer process, which is key to achieving automated and efficient production.

[0039] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
