Description

Technical Field

[0001] This utility model relates to the field of lens sorting machine technology, specifically to a high-efficiency fully automatic lens sorting machine. Background Technology

[0002] The fully automatic film sorting machine is a device that uses machine vision algorithms to drive a high-degree-of-freedom robotic arm to achieve automatic positioning, stable gripping, and precise tray placement of optical lenses. It can improve production efficiency, ensure product quality, and reduce costs through automation.

[0003] According to Chinese Patent Publication No. CN108461437B, "A Fully Automatic High-Efficiency Chip Stacking Machine and its Chip Stacking Method," the main method involves using a spring to push a pusher head, which in turn pushes semiconductor products toward a feeding chain. The rotating feeding chain sequentially places the semiconductor products into the slots on the chain. The continuous rotation of the feeding chain delivers the semiconductor products to the feeding track in the wafer tray. The feeding track receives the materials and then sends the semiconductor products to a clamping clamp below a first motor. The first motor drives the clamping clamp, which holds the semiconductor products and places them onto a chip stacking clamp. The chip stacking clamp then sequentially places the semiconductor products onto a clamping track, which pushes them onto a pusher track. The pusher track sequentially stacks the semiconductor products into the wafer slots, avoiding contamination caused by manual chip stacking, effectively improving production efficiency and reducing operating costs.

[0004] Common fully automatic wafer sorting machines use high-precision positioning machine vision technology to process wafers through feeding, sorting, and unloading, and finally transport the sorted wafers to the next process or storage area. During the wafer sorting process, a robotic arm and a conveyor mechanism are needed to place the wafers transported by the feeding mechanism into the designated positions on the tray.

[0005] However, in actual use, fully automatic film sorting machines require lubrication of the transmission screw. The common lubrication method is manual lubrication at regular intervals. Due to differences in force, angle, or experience, the lubricant distribution may be uneven, affecting the accuracy of the screw transmission. Utility Model Content

[0006] The technical problem to be solved by this utility model is that manual lubrication of the lead screw will result in uneven distribution of lubricant. Therefore, a high-efficiency fully automatic lens sorting machine is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a high-efficiency fully automatic lens sorting machine, including a worktable, a temporary storage mechanism, a conveying mechanism, a tray, a multi-axis robotic arm, and a pneumatic suction cup. Four support plates are fixedly connected to one side of the upper end of the worktable. A first motor is fixedly connected to two of the support plates. A first linear guide is fixedly connected to the output end of the first motor. A first slide rail seat is threaded onto the first linear guide. A second linear guide is rotatably connected between two adjacent first slide rail seats. A second slide rail seat is threaded onto the second linear guide. The multi-axis robotic arm... Both the arm and the tray are fixedly connected to the second slide rail seat. Connecting rings are fixedly connected to both sides of the second slide rail seat. An atomizing nozzle is fixedly connected to the upper end of one of the connecting rings. A connecting pipe is fixedly connected to the upper end of the atomizing nozzle. A water pump is fixedly connected to one side of the connecting pipe. A liquid outlet hole is opened on the bottom side of one of the connecting rings. A conduit is fixedly connected to the bottom side of the liquid outlet hole. A monitoring cylinder is fixedly connected to one side of the conduit. A warning line is opened on one side of the monitoring cylinder. A miniature electric push rod is fixedly connected to the upper side of the monitoring cylinder. A piston is fixedly connected to the upper end of the miniature electric push rod.

[0008] As a preferred technical solution of this utility model, the bottom end of the monitoring cylinder is threaded with a sealing plate, and the sealing plate is fixedly connected with protrusions on all four sides. By setting the sealing plate, it is convenient to clean the lubricating oil.

[0009] As a preferred technical solution of this utility model, a retaining ring is fixedly connected to one side of the connecting ring. The retaining ring is located on the side of the atomizing nozzle away from the second slide rail seat. By setting the retaining ring, the lubricating oil overflowing from the atomizing nozzle can be received.

[0010] As a preferred technical solution of this utility model, a folding sleeve is fixedly connected to one side of the connecting ring. The folding sleeve corresponds to the first slide rail seat and the second slide rail seat respectively. By setting the folding sleeve, the sticking of dust in the external environment can be reduced, which can reduce the stiffness of the linear guide rail rotation.

[0011] As a preferred technical solution of this utility model, an auxiliary rod is movably inserted into one side of the connecting ring. The auxiliary rod is located inside the folding sleeve. By setting the auxiliary rod, the folding sleeve can be limited and supported, and the folding sleeve can be prevented from contacting the limiting rod.

[0012] This utility model has the following advantages: by installing connecting rings and folding sleeves on the first and second linear guides, and by using a water pump to extract lubricating oil and spraying it onto the first and second linear guides through atomizing nozzles, the linear guides are lubricated in a moving manner, simplifying the lubrication process, reducing wear at the transmission screw, reducing uneven application of manual lubricant, and improving the accuracy of the transmission screw.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figure 1-4The illustrated high-efficiency fully automatic lens sorting machine includes a worktable 1, a temporary storage mechanism 2, a conveying mechanism 3, a tray 9, a multi-axis robotic arm 10, and a pneumatic suction cup 11. The temporary storage mechanism 2 includes a conveying structure for conveying materials into a temporary storage box. With the cooperation of the conveying structure and the multi-axis robotic arm, the trays enter the temporary storage box onto plates of different heights. The above structure is a common structure for lens sorting machines, and the model used is a common model in this field. The multi-axis robotic arm 10 has a hydraulic push rod on its bottom side. There are two multi-axis robotic arms 10, with the other one located between the temporary storage mechanism 2 and the conveying mechanism 3. The temporary storage mechanism 2 includes a conveyor belt and a temporary storage mechanism, enabling the Z-axis movement of the pneumatic suction cup 11. Its operating principle and execution program are built into the system and will not be elaborated here. A rotatable cover is installed on the worktable 1, abutting against the upper end of the worktable 1. This reduces dust contact with the lenses and prevents a decrease in the monitoring effect of the sensors on the subsequent lens arrangement mechanism. Four support plates 4 are fixedly connected to one side of the upper end of the worktable 1. Two of the support plates 4 are fixedly connected to a first motor. The first motor drives the first linear guide rail 5 to rotate, causing the first slide rail seat 6 to move. The second motor drives the second linear guide rail 5 to rotate. The guide rail 7 rotates, causing the second slide rail seat 8 to move along the XY axes. The first and second motors are servo motors. Both the first and second slide rail seats 6 and 8 are controlled by motors to roll their rolling elements, cooperating with linear guides to achieve movement of the slide rail seats. The output end of the first motor is fixedly connected to the first linear guide rail 5, and the first slide rail seat 6 is threaded onto the first linear guide rail 5. The structure on both sides of the first slide rail seat 6 is identical to that of the second slide rail seat 8. A second linear guide rail 7 is rotatably connected between two adjacent first slide rail seats 6. A second motor is installed on one side of the first slide rail seat 6, and the output end of the second motor is connected to the second linear guide rail 7. The linear guide rail 7 is fixedly connected, and the second linear guide rail 7 is threadedly connected to the second slide rail seat 8. The multi-axis robotic arm 10 and the tray 9 are both fixedly connected to the second slide rail seat 8. Connecting rings 12 are fixedly connected to both sides of the second slide rail seat 8. One of the connecting rings 12 is fixedly connected to the upper end of an atomizing nozzle 13. The atomizing nozzle 13 follows the Venturi effect to atomize the lubricating oil. A connecting pipe 14 is fixedly connected to the upper end of the atomizing nozzle 13. A water pump 15 is fixedly connected to one side of the connecting pipe 14. A timer can be set on one side of the water pump 15 and connected in series with the control box of the water pump 15. Then, a 50mm trigger is set.The spraying process takes 2 seconds. Water pump 15 is connected to an external lubrication supply structure via connecting pipe 14, drawing lubricant into the atomizing nozzle 13. One of the connecting rings 12 has a liquid outlet 16 on its bottom side. A conduit (with a built-in check valve, not shown in the figure) is fixedly connected to the bottom side of the outlet 16. A monitoring cylinder 17 is fixedly connected to one side of the conduit, and a warning line is provided on one side of the monitoring cylinder 17. When the free atomized lubricant accumulates above the warning line, the sealing plate 20 can be opened for cleaning. A miniature electric push rod 18 is fixedly connected to one side of the upper end of the monitoring cylinder 17, and a piston 19 is fixedly connected to the upper end of the miniature electric push rod 18. Extending the miniature electric push rod 18 causes the piston 19 to move upward, generating negative pressure and rapidly drawing the free atomized lubricant into the monitoring cylinder 17.

[0020] The bottom of the monitoring cylinder 17 is threadedly connected to a sealing plate 20. The sealing plate 20 has protrusions fixedly connected on all four sides. Opening the sealing plate 20 allows the free atomized lubricating fluid to be discharged.

[0021] Among them, a retaining ring 21 is fixedly connected to one side of the connecting ring 12. The retaining ring 21 is located on the side of the atomizing nozzle 13 away from the second slide rail seat 8. By setting the retaining ring 21, it can cooperate with the connecting ring 12 and the second slide rail seat 8 to collect free atomizing liquid.

[0022] Among them, a folding sleeve 22 is fixedly connected to one side of the connecting ring 12. The folding sleeve 22 is made of plastic and can extend and retract under pressure or tension. It is also called a corrugated sleeve. The folding sleeve 22 corresponds to the first slide rail seat 6 and the second slide rail seat 8 respectively. By setting the folding sleeve 22, the dust in the external environment can be prevented from contacting the linear guide rail.

[0023] An auxiliary rod 23 is movably inserted into one side of the connecting ring 12. The auxiliary rod 23 is located inside the folding sleeve 22. By setting the auxiliary rod 23, it can cooperate with the linear guide rail for limiting the position, and at the same time, it can limit the position of the folding sleeve 22 to prevent the folding sleeve 22 from contacting the linear guide rail due to gravity when it is extended.

[0024] Working principle: The temporary storage mechanism 2 on one side of the workbench 1 feeds the material, which moves along the conveyor mechanism 3. Then, the multi-axis robotic arm 10 and the pneumatic suction cup 11 pick up the material and move it onto the tray 9. At this time, the first motor and the second motor operate, driving the first linear guide rail 5 and the second linear guide rail 7 to rotate. Further, the first slide rail seat 6 and the second slide rail seat 8 move. At this time, the second slide rail seat 8 moves to the next process. During the movement of the slide rail seat, the water pump 15 draws external lubricating fluid into the atomizing nozzle 13 and sprays it onto the linear guide rail. Then, the monitoring cylinder 17 is used to monitor the free atomized fluid. It can be cleaned by opening the sealing plate 20.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0026] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
