Description

Technical Field

[0001] The present invention relates to the technical field of vacuum suction cups, and specifically to a vacuum suction cup device for handling purposes. Background Art

[0002] During the production and manufacturing process in a factory, it is usually necessary to handle the products produced. A vacuum suction cup is a common handling device. The Chinese patent with the publication number "CN118358997B" provides a vacuum suction cup device for grasping bagged seasonings. This device can change the position of the suction cups through multiple suction cup mechanisms that can move vertically independently, so as to adapt to the irregularly stacked bagged seasonings, thereby increasing the grasping area of the suction cups and avoiding squeezing the bagged seasonings due to the fixed suction cups, preventing the situation of package rupture in the morning. However, when handling products with holes, the suction cups of this application cannot adsorb at this place, reducing the adsorption force on the products and there is a risk of dropping during the handling process. Summary of the Invention

[0003] The purpose of the present invention is to provide a vacuum suction cup device for handling purposes to solve the problems raised in the above background art.

[0004] To achieve the above-mentioned invention purpose, the present invention adopts the following technical solutions:

[0005] A vacuum suction cup device for handling purposes provided by the present invention includes a mounting plate. One side of the mounting plate is fixedly connected with a vacuum cavity. The side of the vacuum cavity away from the mounting plate is fixedly connected with a vacuum tube for connecting to a vacuum pump. A plurality of mounting openings are provided on the mounting plate, and a suction cup mechanism is fixedly connected in each mounting opening. The end of the suction cup mechanism away from the mounting plate is fixedly connected with a plugging mechanism for controlling the connection between the suction cup mechanism and the vacuum cavity.

[0006] Further, the suction cup mechanism includes a fixed tube fixedly connected in the mounting opening. A suction disc is sleeved and slidably connected on the fixed tube. Symmetrically fixed blocks are fixedly connected to the inner wall of the suction disc away from the fixed tube.

One end of the fixed tube extending into the vacuum cavity is fixedly connected with a connecting sleeve.

[0007] Further, the plugging mechanism includes fixing rods fixedly connected to the inner wall of the fixed tube in an array. One end of the fixing rod away from the inner wall of the fixed tube is fixedly connected with a sliding sleeve. A sliding rod is slidably connected through the sliding sleeve. One end of the sliding rod close to the push rod is fixedly connected with an abutting block. A card slot is provided on the outer wall of the abutting block close to the rolling ball. One end of the sliding rod away from the abutting block is fixedly connected with a plugging ball. The plugging ball is located in the connecting sleeve. A fixing component for fixing the abutting block is fixedly connected to the inner wall of the suction disc close to the abutting block.

[0008] Furthermore, the fixing component includes a push rod fixedly connected to the inner wall of the suction cup near the limit block. A rolling ball is rotatably connected to the end of the push rod away from the suction cup. An installation rod is fixedly connected to the position of the sliding plate near the rolling ball. The end of the installation rod away from the sliding plate penetrates and is slidably connected to a limit rod. A push block is fixedly connected to the end of the limit rod near the rolling ball. A spring is sleeved on the limit rod. One end of the spring is fixedly connected to the push block, and the other end of the spring is fixedly connected to the installation rod.

[0009] Furthermore, one end of the limit rod extends into the card slot.

[0010] Furthermore, the end of the push block away from the sliding plate is arc-shaped.

[0011] Furthermore, the push rod is inclined, and the distance between the push rod and the sliding plate gradually decreases from the end near the suction cup to the other end.

[0012] Furthermore, when the plugging ball plugs the connecting sleeve, the abutting block is located inside the suction cup.

[0013] Furthermore, the diameter of the sliding sleeve is smaller than the diameter of the fixed pipe.

[0014] Furthermore, the end of the connecting sleeve away from the fixed pipe is flared.

[0015] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0016] In the present invention, through the provided plugging mechanism and suction cup mechanism, when the plugging mechanism contacts the surface of the product, the corresponding suction cup mechanism is communicated with the vacuum cavity, so that the suction cup mechanism adsorbs the product, preventing each suction cup mechanism from being in an open state when handling a product with holes, reducing the overall adsorption force, and thus avoiding the product from falling during handling;

[0017] Through the provided suction cup and fixed pipe, when adsorbing a heavier product, the suction cup moves on the fixed pipe and drives the plugging mechanism to plug, increasing the space inside the suction cup and improving the adsorption force of the suction cup on the product, further avoiding the product from falling.

Detailed implementation manners

[0027] In order to enable those skilled in the art of the present technology to better understand the solution of 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 in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] Please refer to Figures 1 to 5 , the present invention provides a vacuum suction cup device for handling, including a mounting plate 1, one side of the mounting plate 1 is fixedly connected with a vacuum cavity 2, the side of the vacuum cavity 2 away from the mounting plate 1 is fixedly connected with a vacuum tube 3 for connecting with a vacuum pump, a plurality of mounting openings 4 are formed on the mounting plate 1, a suction cup mechanism 5 is fixedly connected in each mounting opening 4, and one end of the suction cup mechanism 5 away from the mounting plate 1 is fixedly connected with a plugging mechanism 6 for controlling the communication between the suction cup mechanism 5 and the vacuum cavity 2.

[0029] In the initial state, the blocking mechanism 6 blocks the adsorption part of the suction cup mechanism 5 from the vacuum cavity 2. When carrying out handling, the suction cup mechanism 5 is moved to the product to be handled through an external moving mechanism. When the blocking mechanism 6 touches the surface of the product, the blocking mechanism 6 no longer blocks the vacuum cavity 2 and the suction cup mechanism 5, making the vacuum cavity 2 and the suction cup mechanism 5 communicate with each other. Subsequently, the vacuum cavity 2 is evacuated by a vacuum pump, so that a negative pressure is generated in the vacuum cavity 2 and the suction cup mechanism 5 connected to it, thereby generating an adsorption force on the product to be handled, and then handling the product, adsorbing the product to be handled, preventing that when handling a product with holes, each suction cup mechanism 5 is in an open state, reducing the overall adsorption force, and thus avoiding the product from falling during handling.

[0030] Please refer to Figure 3 , the suction cup mechanism 5 includes a fixed pipe 7 fixedly connected to the installation port 4. A suction cup 8 is sleeved and slidably connected to the fixed pipe 7. The inner wall of the suction cup 8 far from the fixed pipe 7 is symmetrically and fixedly connected with limit blocks 9. One end of the fixed pipe 7 located inside the suction cup 8 is fixedly connected with a sliding plate 10. One end of the fixed pipe 7 extending into the vacuum cavity 2 is fixedly connected with a connecting sleeve 11.

[0031] In the initial state, due to the gravity of the suction cup 8 itself, the upper end of the suction cup 8 contacts the upper end of the sliding plate 10. When carrying out handling, the suction cup 8 will move to the product and contact the product surface. The suction cup 8 slides on the fixed pipe 7, so that the sliding plate 10 relatively moves to a position where it abuts against the limit block 9, thereby reducing the space where the suction cup 8 communicates with the vacuum cavity 2. Thus, when the vacuum pump is started, a negative pressure can be quickly generated in the suction cup 8, and then the product can be quickly adsorbed and handled, improving the overall handling speed.

[0032] Please refer to Figure 4 and Figure 5 , the blocking mechanism 6 includes fixing rods 12 fixedly connected to the inner wall of the fixed pipe 7 in an array. One end of the fixing rod 12 far from the inner wall of the fixed pipe 7 is fixedly connected with a sliding sleeve 13. A sliding rod 14 is slidably connected through the sliding sleeve 13. One end of the sliding rod 14 close to the push rod 19 is fixedly connected with an abutting block 15. A clamping groove 16 is opened on the outer wall of the abutting block 15 close to the rolling ball 20. One end of the sliding rod 14 far from the abutting block 15 is fixedly connected with a blocking ball 17. The blocking ball 17 is located inside the connecting sleeve 11. A fixing component 18 for fixedly abutting the abutting block 15 is fixedly connected to the inner wall of the suction cup 8 close to the abutting block 15.

[0033] Please refer to Figure 5, the fixing component 18 includes a push rod 19 fixedly connected to the inner wall of the suction cup 8 near the limit block 9. One end of the push rod 19 away from the suction cup 8 is rotatably connected with a rolling ball 20. A mounting rod 21 is fixedly connected to the position of the sliding plate 10 near the rolling ball 20. One end of the mounting rod 21 away from the sliding plate 10 is slidably connected through a limit rod 22. One end of the limit rod 22 near the rolling ball 20 is fixedly connected with a push block 23. A spring 24 is sleeved on the limit rod 22. One end of the spring 24 is fixedly connected with the push block 23, and the other end of the spring 24 is fixedly connected with the mounting rod 21.

[0034] In the initial state, under the action of the self-gravity of the plugging ball 17, the plugging ball 17 plugs the connection sleeve 11 and the vacuum cavity 2. When handling a relatively heavy product, when the suction cup 8 moves to the product and contacts the surface of the product, the abutting block 15 contacts the surface of the product and moves the abutting block 15. The movement of the abutting block 15 drives the movement of the sliding rod 14, and the movement of the sliding rod 14 drives the movement of the plugging ball 17, so that the plugging ball 17 no longer plugs the connection sleeve 11 and the vacuum cavity 2, making the connection sleeve 11 and the vacuum cavity 2 communicate. A negative pressure is generated in the suction cup 8 to adsorb the product. At the same time, when the suction cup 8 moves, the suction cup 8 drives the movement of the push rod 19, the movement of the push rod 19 drives the movement of the rolling ball 20, the rolling ball 20 abuts against the push block 23 and drives the push block 23 to move against the elastic force of the spring 24 towards the abutting block 15. The movement of the push block 23 drives the movement of the limit rod 22, so that the other end of the limit rod 22 enters the card slot 16, so that the vacuum cavity 2 remains in a state of being connected to the suction cup 8 to handle the product. When handling a heavier product, the suction cup 8 moves downward under the drive of the gravity of the product. The movement of the suction cup 8 drives the push block 23 to move downward, so that the rolling ball 20 is separated from the push block 23. Under the action of the spring 24, the limit rod 22 is separated from the card slot 16, so that the plugging ball 17 plugs the vacuum cavity 2 and the suction cup 8 under its own gravity. When the suction cup 8 descends, the space between the suction cup 8 and the sliding plate 10 becomes larger, so that the negative pressure in the suction cup 8 increases, improving the adsorption force of the suction cup 8 on the product and preventing the product from falling.

[0035] Please refer to Figure 5 , one end of the limit rod 22 extends into the card slot 16, so that the limit rod 22 limits the abutting block 15.

[0036] Please refer to Figure 5 , one end of the push block 23 away from the sliding plate 10 is arc-shaped, so that the push rod 19 can easily drive the push block 23 to move through the rolling ball 20.

[0037] Please refer to Figure 4, the push rod 19 is inclined, and the distance between the push rod 19 and the sliding plate 10 gradually decreases from the end close to the suction cup 8 to the other end, which is convenient for the push rod 19 to drive the push block 23 to move through the rolling ball 20.

[0038] Please refer to Figure 3 , when the plugging ball 17 plugs the connecting sleeve 11, the abutting block 15 is located inside the suction cup 8. When the abutting block 15 contacts the product, the space between the suction cup 8 and the product is in a relatively small state, and a negative pressure capable of stably adsorbing the product can be quickly generated.

[0039] Please refer to Figure 5 , the diameter of the sliding sleeve 13 is smaller than that of the fixed tube 7, and there is a space between the sliding sleeve 13 and the fixed tube 7, so that the air in the suction cup 8 can be pumped out through this place, and the negative pressure of the product in the suction cup 8 adsorbs the product.

[0040] Please refer to Figure 4 , one end of the connecting sleeve 11 away from the fixed tube 7 is flared, which can quickly connect the vacuum cavity 2 and the suction cup 8 when the plugging ball 17 moves.

[0041] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
