Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to a robotic arm with adjustable adsorption force. Background Technology

[0002] With the continuous development of industrial automation, the application of robotic arms has become a trend. In the field of plastic granule palletizing, the application of robotic arms can quickly and accurately complete palletizing tasks, improve production efficiency and palletizing quality, reduce labor costs and labor intensity of workers, and improve the level of enterprise automation.

[0003] In order to quickly and accurately pick up, transport and stack products, existing equipment usually uses suction cups installed on robotic arms. The suction force of the suction cups can quickly transfer the injection molded products, thereby reducing waiting time and operational errors in the production process and improving overall production efficiency.

[0004] However, since the quality of products of different specifications varies, the existing suction cups usually have a fixed suction force. This can lead to situations where the suction force of the suction cups is insufficient to grip products of different specifications, causing the products to fall and potentially become damaged. Consequently, the efficiency of product handling and palletizing is affected. Utility Model Content

[0005] The purpose of this invention is to provide a robotic arm with adjustable adsorption force to solve the problem mentioned in the background art where insufficient adsorption force may occur when adsorbing products of different specifications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A manipulator with adjustable suction force, comprising: an injection molding equipment body, a manipulator body mounted on the injection molding equipment body, a mounting plate mounted on the manipulator body, a protective cylinder mounted on the mounting plate, a connecting hose mounted inside the protective cylinder, and a suction cup mounted on the connecting hose; further comprising: an adjustment component mounted on the protective cylinder, the adjustment component including a sliding plate mounted on the protective cylinder, a threaded rod mounted on the sliding plate, a fixed plate mounted on the threaded rod, and a compression block mounted on the fixed plate; the adjustment component is used for adjusting the shape of the connecting hose; and a buffer component mounted on the fixed plate, the buffer component including a torsion spring mounted on the fixed plate, a telescopic plate mounted on the torsion spring, and an anti-collision ball mounted on the telescopic plate; the buffer component is used for buffering during suction cup operation.

[0007] Preferably, the adjustment assembly further includes two sets of T-shaped blocks symmetrically arranged inside the sliding plate, and a T-shaped groove is provided on the protective cylinder corresponding to the T-shaped blocks, with the T-shaped blocks movably arranged in the T-shaped groove.

[0008] Preferably, the threaded rod is threaded onto the sliding plate, a handle is fixedly mounted on one side of the threaded rod, and the side of the threaded rod near the suction cup is rotatably mounted on the fixed plate.

[0009] Preferably, a first crank is rotatably provided on the side of the sliding plate near the fixed plate, the rotation of the first crank is provided on the extrusion block, and a second crank is rotatably provided between the extrusion block and the fixed plate.

[0010] Preferably, the connecting hose is located inside the protective cylinder, and a through groove is provided on the protective cylinder corresponding to the extrusion block, the through groove penetrating the protective cylinder.

[0011] Preferably, the buffer assembly further includes multiple sets of connectors evenly arranged at the bottom of the fixed plate. Two sets of storage slots are symmetrically arranged on the inner side of the connectors. A rotating shaft is rotatably arranged on the inner side of the storage slots, and a telescopic plate is arranged on the outer side of the rotating shaft.

[0012] Preferably, the torsion spring is disposed between the telescopic plate and the storage slot, and the torsion spring is disposed on the outside of the rotating shaft.

[0013] Preferably, the anti-collision ball is positioned on the telescopic plate away from the fixed plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When it is necessary to move products of different specifications, the staff will turn the handle according to the suction force required to move the product. This will cause the screw rod to drive the squeezing block to squeeze the connecting hose, thereby changing the shape of the suction port. The shape of the suction port can be changed between circles, ovals, slits, etc. This allows the flow rate of gas through the suction port to be adjusted, thereby adjusting the suction force of the suction cup and achieving stable adsorption of products of different specifications.

[0016] To prevent the suction cup from directly impacting the product when gripping it, anti-collision balls are used to protect the suction cup. The torsion springs then return the anti-collision balls to their original position after the suction cup has transferred the product, thus cushioning the next product gripping.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1 - Figure 5 As shown, this application provides a manipulator with adjustable adsorption force, including: an injection molding equipment body 1, a manipulator body 2 disposed on the injection molding equipment body 1, a mounting plate 3 disposed on the manipulator body 2, a protective cylinder 4 disposed on the mounting plate 3, a connecting hose 6 disposed inside the protective cylinder 4, a suction cup 5 disposed on the connecting hose 6, and further including: an adjustment component disposed on the protective cylinder 4, the adjustment component including a sliding plate 8 disposed on the protective cylinder 4, a threaded rod 16 disposed on the sliding plate 8, a fixing plate 7 disposed on the threaded rod 16, and an extrusion block 12 disposed on the fixing plate 7, the adjustment component being used for adjusting the shape of the connecting hose 6.

[0026] Specifically, such as Figure 4 As shown, the adjustment assembly also includes two sets of T-shaped blocks 14 symmetrically arranged inside the sliding plate 8. The protective cylinder 4 is provided with a T-shaped groove 9 corresponding to the T-shaped blocks 14. The T-shaped blocks 14 are movably arranged in the T-shaped groove 9. Through the cooperation between the T-shaped groove 9 and the T-shaped blocks 14, the movement distance of the sliding plate 8 can be limited.

[0027] Specifically, such as Figure 3As shown, the threaded rod 16 is threaded onto the sliding plate 8, and a handle 17 is fixedly mounted on one side of the threaded rod 16. The side of the threaded rod 16 closest to the suction cup 5 is rotatably mounted on the fixed plate 7. The handle 17 enables stable control of the rotation of the threaded rod 16.

[0028] Specifically, such as Figure 3 As shown, a first crank 10 is rotatably mounted on the side of the sliding plate 8 near the fixed plate 7. The rotation of the first crank 10 is mounted on the extrusion block 12. A second crank 11 is rotatably mounted between the extrusion block 12 and the fixed plate 7. Through the cooperation of the first crank 10 and the second crank 11, the extrusion block 12 can be easily moved.

[0029] Specifically, such as Figure 3 As shown, the connecting hose 6 is located inside the protective cylinder 4. The protective cylinder 4 is provided with a through groove 13 corresponding to the extrusion block 12. The through groove 13 penetrates the protective cylinder 4. The through groove 13 facilitates the extrusion block 12 to extrude the connecting hose 6.

[0030] A buffer assembly is provided on the fixed plate 7. The buffer assembly includes a torsion spring 21 provided on the fixed plate 7, a telescopic plate 20 provided on the torsion spring 21, and an anti-collision ball 15 provided on the telescopic plate 20. The buffer assembly is used for buffering when the suction cup 5 is working.

[0031] Specifically, such as Figure 5 As shown, the buffer assembly also includes multiple sets of connectors 18 evenly arranged at the bottom of the fixed plate 7. Two sets of storage slots 19 are symmetrically arranged on the inner side of the connectors 18. A rotating shaft 22 is rotatably arranged on the inner side of the storage slots 19. A telescopic plate 20 is arranged on the outer side of the rotating shaft 22. Through the extension and retraction of the telescopic plate 20, it can automatically return to its original position when the anti-collision ball 15 is removed from the product.

[0032] Specifically, such as Figure 5 As shown, the torsion spring 21 is disposed between the telescopic plate 20 and the storage groove 19. The torsion spring 21 is disposed on the outside of the rotating shaft 22. Through the elastic force of the torsion spring 21, the anti-collision ball 15 can be driven to return to its original position.

[0033] Specifically, such as Figure 5 As shown, the anti-collision ball 15 is set on the side of the telescopic plate 20 away from the fixed plate 7. The anti-collision ball 15 can effectively protect the suction cup 5.

[0034] In this embodiment: when the suction force of the suction cup 5 needs to be adjusted, the operator can turn the handle 17 to drive the threaded rod 16 to rotate. The rotation of the threaded rod 16 can drive the sliding plate 8 to move, thereby driving the squeezing block 12 to squeeze or release the connecting hose 6. This can change the shape of the suction port, so that the flow rate of gas through the suction port can be adjusted, which is convenient for the stable suction of products of different specifications. The anti-collision ball 15 and the telescopic plate 20 can achieve the protection function of the suction cup 5. And through the elasticity of the torsion spring 21, when the suction cup 5 has finished transferring the product and is separated from the product, it can drive the anti-collision ball 15 to return to its original position.

[0035] Specifically, when the suction force of the suction cup 5 needs to be adjusted, the operator turns the handle 17, which moves the sliding plate 8 via the threaded rod 16. At this time, the T-shaped block 14 moves within the T-shaped groove 9. The operator can then move the squeezing block 12 by cooperating the first crank 10 and the second crank 11 according to the required suction force. This allows for precise squeezing of the connecting hose 6 by the squeezing block 12. Therefore, by changing the shape of the suction port, the flow rate of the gas can be controlled, thereby achieving the purpose of adjusting the suction force. This allows the suction cup 5 to adjust the suction force according to the product specifications. To prevent the suction cup 5 from directly impacting the product during operation and causing damage, the telescopic plate 20 and the anti-collision ball 15 work together to provide a buffering effect when the suction cup 5 contacts the product, thus protecting the suction cup 5. When the suction cup 5 detaches from the product, the elasticity of the torsion spring 21 can drive the anti-collision ball 15 back to its original position, ensuring that the anti-collision ball 15 can function normally as a buffer during the next product gripping process.
