Technical Field

[0001] This utility model relates to the field of gripper technology, specifically a gripper with a protective device. Background Technology

[0002] In existing automated production equipment, grippers are used as a key actuator in various stages of material handling, assembly, and processing.

[0003] Traditional gripper drive mechanisms mostly rely on hydraulic cylinders as a power source. The piston movement of the hydraulic cylinder drives the extension and retraction of the transmission shaft, thereby realizing the opening and closing action of the gripper and completing the gripping and releasing of the product.

[0004] However, during the frequent extension and retraction of the drive shaft, the working environment is often quite complex, and dust and impurities in the air can easily adhere to the surface of the drive shaft, causing the drive shaft to run unevenly. This prevents the grippers from opening and closing smoothly, ultimately leading to a reduction in processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a gripper with a protective device to solve the problem mentioned in the background art where the lack of protection for the drive shaft causes dust in the air to adhere to it.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A gripper with a protective device includes: a mounting plate on which a drive shaft is mounted, a lug is mounted on the drive shaft, and a gripper arm is mounted on the lug; a protective assembly mounted on the mounting plate, the protective assembly including a protective ring mounted on the mounting plate, a connecting ring mounted on the protective ring, and a first silicone plate mounted on the connecting ring; and a lubrication assembly mounted on the connecting ring, the lubrication assembly including an oil reservoir mounted on the connecting ring, and a lubricating sponge mounted on the oil reservoir; the lubrication assembly for lubricating the drive shaft.

[0008] Preferably, the protective component further includes a connecting groove disposed inside the protective ring, a sliding plate movably disposed inside the connecting groove, protrusions disposed on both sides of the sliding plate, a sliding groove disposed inside the connecting groove corresponding to the protrusions, the protrusions being movably disposed in the sliding grooves, and a second silicone plate disposed at the upper end of the protective ring.

[0011] Preferably, the device is provided with multiple sets of protective rings, the multiple sets of protective rings are of different sizes and are slidably connected to each other, and the bottom of each set of protective rings is connected by a sliding plate. The uppermost set of sliding plates is provided with a connecting ring, and the first silicone plate is in contact with the hanging ear.

[0012] Preferably, the lubrication assembly further includes lead screws disposed on both sides of the connecting ring, the lead screws passing through the connecting ring, and a rotating component being disposed at one end of the connecting ring.

[0013] Preferably, one end of the lead screw is mounted on the oil reservoir, and a square telescopic rod is mounted on one side of the oil reservoir, with one end of the square telescopic rod located inside the connecting ring.

[0014] Preferably, a connecting pipe is provided on one side of the oil storage tank, and the connecting pipe passes through the connecting ring and extends to the outside of the connecting ring.

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

[0028] 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.

[0029] 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.

[0030] like Figure 1-9 As shown, this application provides a gripper with a protective device, including: a mounting plate 2, a drive shaft 5 disposed on the mounting plate 2, a hanging ear 6 disposed on the drive shaft 5, a gripper arm 21 disposed on the hanging ear 6, a protective assembly disposed on the mounting plate 2, the protective assembly including a protective ring 7 disposed on the mounting plate 2, a connecting ring 8 disposed on the protective ring 7, and a first silicone plate 10 disposed on the connecting ring 8, the protective assembly being used for the protection of the drive shaft 5.

[0031] Specifically, such as Figure 9 As shown, the protective assembly also includes a connecting groove 18 disposed inside the protective ring 7. A sliding plate 17 is movably disposed inside the connecting groove 18. Both sides of the sliding plate 17 are provided with protrusions 3. A sliding groove 20 is provided inside the connecting groove 18 corresponding to the protrusions 3. The protrusions 3 are movably disposed in the sliding groove 20. A second silicone plate 16 is provided at the upper end of the protective ring 7. Through the cooperation of the protrusions 3 and the sliding groove 20, the sliding plate 17 can be limited to move inside the connecting groove 18.

[0032] Specifically, such as Figure 9 As shown, a roller 1 is provided at one end of the sliding plate 17, and a slide rail 19 is provided inside the connecting groove 18 corresponding to the roller 1. The roller 1 is movably disposed in the slide rail 19. The cooperation between the roller 1 and the slide rail 19 allows the sliding plate 17 to move more flexibly, thereby enabling the multiple sets of protective rings 7 and connecting rings 8 to move more flexibly.

[0033] Specifically, such as Figure 9 As shown, the bottom of the sliding plate 17 is provided with an elastic element 4. One end of the elastic element 4 is located in the connecting groove 18. Through the elastic force of the elastic element 4, the protective ring 7 and the connecting ring 8 can move with the extension and retraction of the transmission shaft 5, which can provide more comprehensive protection for the transmission shaft 5.

[0034] Specifically, such as Figure 4 As shown, this device is equipped with multiple sets of protective rings 7, which are of different sizes and are slidably connected to each other. The bottom of each set of protective rings 7 is connected by a sliding plate 17. The uppermost set of sliding plates 17 is equipped with a connecting ring 8. The first silicone plate 10 contacts the ear 6. The first silicone plate 10 wraps the connection between the ear 6 and the drive shaft 5, which can effectively prevent dust from adhering to the drive shaft 5.

[0035] A lubrication assembly is provided on the connecting ring 8. The lubrication assembly includes an oil reservoir 15 provided on the connecting ring 8 and a lubricating sponge 9 provided on the oil reservoir 15. The lubrication assembly is used for lubrication of the drive shaft 5.

[0036] Specifically, such as Figure 6 As shown, the lubrication assembly also includes lead screws 12 disposed on both sides of the connecting ring 8, and the lead screws 12 pass through the connecting ring 8. One end of the connecting ring 8 is provided with a rotating member 11. By rotating the rotating member 11, the lead screws 12 can be driven to rotate.

[0037] Specifically, such as Figure 6 As shown, one end of the lead screw 12 is mounted on the oil storage tank 15, and a square telescopic rod 14 is mounted on one side of the oil storage tank 15. One end of the square telescopic rod 14 is mounted inside the connecting ring 8. The square telescopic rod 14 can limit the movement direction of the oil storage tank 15, making it easier for the lead screw 12, which is rotatably connected to the oil storage tank 15, to drive its movement.

[0038] Specifically, such as Figure 6 As shown, a connecting pipe 13 is provided on one side of the oil storage tank 15, and the connecting pipe 13 passes through the connecting ring 8 and extends to the outside of the connecting ring 8. The setting of the connecting pipe 13 makes it convenient for the staff to pour the lubricating oil into the oil storage tank 15, so that the lubricating oil inside the oil storage tank 15 can be evenly injected into the lubricating sponge 9.

[0039] In this embodiment: the elastic force of the elastic element 4 allows multiple sets of protective rings 7 and connecting rings 8 to move with the movement of the transmission shaft 5, thereby providing more comprehensive protection for the transmission shaft 5. The first silicone plate 10 effectively prevents dust from adhering to the transmission shaft 5 from the connection between the lug 6 and the transmission shaft 5. By rotating the lead screw 12, the lubricating sponge 9 can be tightly attached to the transmission shaft 5, allowing the lubricating oil to be more evenly lubricated through the lubricating sponge 9, thus making the transmission shaft 5 run more smoothly.

[0040] Specifically, this solution involves multiple sets of protective rings 7 and one set of connecting rings 8, providing comprehensive protection for the drive shaft 5. The first set of protective rings 7 is fixedly mounted on the mounting plate 2. A connecting groove 18 is provided inside the protective ring 7, allowing the sliding plate 17 to slide within the groove 18. The protrusion 3 slides within the slide groove 20, limiting the movement direction of the sliding plate 17 and preventing it from shifting during movement. The roller 1 slides within the slide rail 19, increasing the flexibility of the sliding plate 17 and making its movement smoother. The second set of protective rings 7 is mounted on the sliding plate 17, and the elastic element 4 at the bottom of the sliding plate 17 facilitates protection against... The protective ring 7 extends and retracts, causing the protective ring 7 and the connecting ring 8 to extend and retract along with the transmission shaft 5. The second silicone plate 16 at the upper end of the protective ring 7 can protect its connection point, while the first silicone plate 10 at the top of the connecting ring 8 can prevent dust from adhering to the transmission shaft 5 from the connection between the transmission shaft 5 and the lug 6. When the transmission shaft 5 experiences obstructed extension and retraction, rotating the rotating component 11 causes the lead screw 12 to move the oil reservoir 15, thereby allowing the lubricating sponge 9 to come into contact with the transmission shaft 5. Lubricating oil is added to the oil reservoir 15 through the connecting pipe 13, allowing the lubricating oil to enter the interior of the lubricating sponge 9 through the oil reservoir 15, thus enabling the lubricating sponge 9 to evenly apply the lubricating oil to the transmission shaft 5.

[0041] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

[0042] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
