Description

Technical Field

[0001] The utility model relates to a lens packaging and feeding mechanism. Background Art

[0002] In the eyewear industry, the packaging of lenses is an important link, which not only relates to the appearance of the product, but also involves product protection and transportation safety. Traditional lens packaging methods mostly adopt manual operation, with low efficiency and prone to problems such as inconsistent packaging and waste of packaging materials. With the development of automation technology, automated packaging equipment has gradually been introduced into the lens packaging process to improve production efficiency and packaging quality.

[0003] However, when the existing automated packaging equipment processes lens packaging paper bags, most of them use a single suction cup for adsorption and feeding. However, the adsorption force of a single suction cup is not sufficient to overcome the weight or friction of the paper bag, and the paper bag may fall off during transportation, resulting in packaging interruption or product damage. Therefore, a lens packaging and feeding mechanism is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a lens packaging and feeding mechanism to solve the problem that when the existing automated packaging equipment processes lens packaging paper bags, most of them use a single suction cup for adsorption and feeding, but the adsorption force of a single suction cup is not sufficient to overcome the weight or friction of the paper bag, and the paper bag may fall off during transportation, resulting in packaging interruption or product damage as mentioned in the above background art.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A lens packaging and feeding mechanism includes a carrier frame, a bin for loading lens packaging paper bags is arranged at the carrier frame, a double-end output cylinder is connected to the output end of the carrier frame located at the bin through a cylinder fixing plate, two output ends of the double-end output cylinder are respectively connected with a piston rod and a movable cylinder rod, and the piston rod and the movable cylinder rod are both connected with a gas collecting row;

[0006] A suction cup assembly is arranged on one side of the gas collecting row away from the double-end output cylinder;

[0007] Wherein, the double-end output cylinder controls the movement of the gas collecting row and the suction cup assembly to adsorb the lens packaging paper bag respectively through the piston rod and the movable cylinder rod.

[0008] Preferably, a connecting plate is arranged on one side of the piston rod away from the double-end output cylinder, and the connecting plate is connected with the gas collecting row.

[0009] Preferably, a gas collecting channel is arranged inside the gas collecting row, and the input and output ends of the gas collecting channel are respectively connected with the suction cup assembly and the movable cylinder rod.

[0010] Preferably, the suction cup assembly includes a sealing cylinder disposed outside the gas collecting channel. An adapter cylinder is arranged inside the sealing cylinder. A paper bag suction cup is connected to one side of the adapter cylinder away from the sealing cylinder.

[0011] Preferably, a sealing piston is provided on the side of the adapter cylinder away from the paper bag suction cup, and the sealing piston cooperates with the inner wall of the sealing cylinder.

[0012] Preferably, a return spring is arranged on the outer periphery of the adapter cylinder, and the return spring is located between the sealing cylinder and the paper bag suction cup.

[0013] Preferably, a through hole for adsorption is provided in the middle of the paper bag suction cup.

[0014] Preferably, the gas collecting row is convex in shape, and the number of the suction cup assemblies is three groups.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] By providing the suction cup assembly, through the compression and release of the return spring and the interaction between the sealing cylinder and the adapter cylinder, the double adsorption force of the paper bag suction cup is enhanced, effectively overcoming the problem of insufficient adsorption force of a single suction cup.

[0017] The combined use of the sealing piston and the sealing cylinder improves the sealing performance, ensuring that the paper bag will not fall off due to air pressure changes during adsorption and transportation, and enhancing the stability of the entire packaging process.

[0018] Due to the adoption of the enhanced adsorption mechanism, the paper bag falling off caused by insufficient adsorption force is reduced, thereby reducing the risk of interruption in the packaging process and improving the continuity and reliability of production.

[0019] By ensuring the firm adsorption of the paper bag during transportation, the packaging quality problems caused by the paper bag falling are avoided, and the packaging quality of the final product is improved.

[0020] The design of this mechanism allows for the effective adsorption of paper bags of different specifications, improving the adaptability and flexibility of the equipment, and reducing the number of times of replacing components or adjusting the equipment due to different specifications.

[0021] Due to the simplification of the structural design, the number of mechanical components is reduced, making the maintenance of the equipment more convenient and reducing the maintenance cost.

[0022] Through the automated adsorption and release mechanism, the manual intervention is reduced, and the production efficiency is improved. Especially when dealing with large batches of orders, the production cycle can be significantly shortened.

[0023] The use of pneumatic drive has lower energy consumption compared with electric drive, meeting the energy conservation and environmental protection requirements of modern industrial production.

[0024] The automated packaging process reduces the chance of direct human contact with paper bags and decreases potential safety hazards during operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to facilitate the solution of the problem that most existing automated packaging equipment uses a single suction cup for adsorption and feeding when dealing with lens packaging paper bags, but the adsorption force of a single suction cup is not sufficient to overcome the weight or friction of the paper bag, and the paper bag may fall off during transportation, resulting in packaging interruption or product damage, an embodiment of the present utility model provides a lens packaging feeding mechanism.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-3 , the present utility model provides a lens packaging feeding mechanism, including a carrier frame 100, a silo 200 for loading lens packaging paper bags is arranged at the carrier frame 100, a double-ended output cylinder 400 is connected to the output end of the carrier frame 100 located at the silo 200 through a cylinder fixing plate 300, two output ends of the double-ended output cylinder 400 are respectively connected with a piston rod 401 and a movable cylinder rod 402, and the piston rod 401 and the movable cylinder rod 402 are both connected with an air collecting row 500; a connecting plate 4011 is arranged on the side of the piston rod 401 away from the double-ended output cylinder 400, and the connecting plate 4011 is connected with the air collecting row 500.

[0031] An air collecting row 500 is internally provided with an air collecting channel 501, and the input and output ends of the air collecting channel 501 are respectively connected to a suction cup assembly 600 and a movable cylinder rod 402. The air collecting row 500 is convex in shape, and the number of the suction cup assemblies 600 is three groups.

[0032] A suction cup assembly 600 is arranged on one side of the air collecting row 500 away from the double-end output cylinder 400; the suction cup assembly 600 includes a sealing cylinder 601 arranged outside the air collecting channel 501, an adapter cylinder 602 is arranged inside the sealing cylinder 601, and a paper bag suction cup 603 is connected to one side of the adapter cylinder 602 away from the sealing cylinder 601. A sealing piston 604 is arranged on one side of the adapter cylinder 602 away from the paper bag suction cup 603, and the sealing piston 604 is matched with the inner wall of the sealing cylinder 601. A return spring 605 is arranged on the outer periphery of the adapter cylinder 602, and the return spring 605 is located between the sealing cylinder 601 and the paper bag suction cup 603. A through hole 6031 for adsorption is formed in the middle of the paper bag suction cup 603.

[0033] Wherein, the double-end output cylinder 400 controls the movement of the air collecting row 500 and the adsorption of the lens packaging paper bag by the suction cup assembly 600 through a piston rod 401 and a movable cylinder rod 402 respectively.

[0034] The working principle of a lens packaging feeding mechanism provided by the present utility model is as follows:

[0035] First, load the lens packaging paper bags into the bin 200 to ensure that the paper bags are neatly arranged for subsequent material taking.

[0036] Start the cylinder: Start the double-end output cylinder 400. Through the connection between the cylinder fixing plate 300 and the carrier 100, ensure that the cylinder can work normally at the front end of the bin 200.

[0037] Move the air collecting row 500: The double-end output cylinder 400 controls the movement of the air collecting row 500 through the piston rod 401, so that it reaches the position of the lens packaging paper bag in the bin 200 and is ready to adsorb the paper bag;

[0038] Adsorb the paper bag: The paper bag suction cup 603 abuts against the position of the lens packaging paper bag. The paper bag suction cup 603 moves towards the sealing cylinder 601 side through the adapter cylinder 602 under force, and then compresses the return spring 605 between the sealing cylinder 601 and the adapter cylinder 602. The return spring 605 is compressed and deformed under force, and the sealing cylinder 601 connected to the paper bag suction cup 603 retracts, squeezing the paper bag suction cup 603 against the paper bag side. The air inside the paper bag suction cup 603 is discharged to generate negative pressure for preliminary adsorption;

[0039] Meanwhile, the elastic force generated by the reset spring 605 acts in the opposite direction on the side of the paper bag suction cup 603, squeezing the air inside the sealing cylinder 601, causing it to be discharged through the through hole 6031 on the side of the paper bag suction cup 603. The air pressure inside it decreases, and the adsorption force is increased through the paper bag suction cup 603;

[0040] Then, the double-ended output cylinder 400 controls the movable cylinder rod 402 to be connected through the air collection channel 501, and uses the suction force of the suction cup assembly 600 to adsorb the paper bag, ensuring that the paper bag is firmly attached to the suction cup.

[0041] Move the suction cup assembly 600 adsorbed with the paper bag to the predetermined packaging position, release the suction force of the suction cup assembly 600, so that the paper bag is separated from the suction cup, complete one feeding, repeat the above steps, and continue to pick up, adsorb and release the next batch of paper bags to achieve a continuous automated packaging process.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
