[0002] In the manufacturing process of a factory, it is usually necessary to transport the manufactured products, and a vacuum suction cup is a common transport device. A Chinese patent with publication number "CN118358997B" provides a vacuum suction cup device for grabbing bagged condiments. The device uses multiple suction cup mechanisms that can move vertically independently to change the position of the suction cup to adapt to bagged condiments stacked in irregular shapes, thereby increasing the gripping area of ​​the suction cup and avoiding squeezing of the bagged condiments due to the fixation of the suction cup to prevent the package from breaking in the morning. However, when transporting products with holes, the suction cup cannot adsorb the holes, which reduces the adsorption force on the product and there is a risk of falling during transportation.

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] See also Figures 1 to 5 The present invention provides a vacuum suction cup device for transportation, comprising a mounting plate 1, a vacuum chamber 2 is fixedly connected to one side of the mounting plate 1, a vacuum tube 3 for connecting to a vacuum pump is fixedly connected to the side of the vacuum chamber 2 away from the mounting plate 1, a plurality of mounting ports 4 are opened on the mounting plate 1, a suction cup mechanism 5 is fixedly connected to each of the mounting ports 4, and a blocking mechanism 6 for controlling the suction cup mechanism 5 to be connected to the vacuum chamber 2 is fixedly connected to the end of the suction cup mechanism 5 away from the mounting plate 1.

[0029] In the initial state, the blocking mechanism 6 blocks the adsorption point of the suction cup mechanism 5 with the vacuum chamber 2. During transportation, the suction cup mechanism 5 is moved to the position of the product to be transported by an external moving mechanism. When the blocking mechanism 6 contacts the surface of the product, the blocking mechanism 6 will no longer block the vacuum chamber 2 and the suction cup mechanism 5, so that the vacuum chamber 2 and the suction cup mechanism 5 are connected. Subsequently, the vacuum chamber 2 is evacuated by a vacuum pump, so that negative pressure is generated in the vacuum chamber 2 and the suction cup mechanism 5 connected thereto, thereby generating an adsorption force on the product to be transported, and then the product is transported and adsorbed to prevent each suction cup mechanism 5 from being in an open state when transporting products with holes, thereby reducing the overall adsorption force and preventing the product from falling during transportation.

[0030] See also Figure 3 The suction cup mechanism 5 includes a fixed tube 7 fixedly connected to the installation port 4, a suction cup 8 is slidably connected to the fixed tube 7, and the suction cup 8 is symmetrically fixedly connected to a limiting block 9 away from the inner wall of the fixed tube 7. One end of the fixed tube 7 located in the suction cup 8 is fixedly connected to a sliding plate 10, and one end of the fixed tube 7 extending into the vacuum chamber 2 is fixedly connected to a connecting sleeve 11.

[0031] In the initial state, due to the gravity of the adsorption disk 8 itself, the upper end of the adsorption disk 8 contacts the upper end of the sliding plate 10. During transportation, the adsorption disk 8 will move to the product and contact the surface of the product. The adsorption disk 8 slides on the fixed tube 7, causing the sliding plate 10 to move relatively to a position abutting against the limit block 9, thereby reducing the space connecting the adsorption disk 8 and the vacuum chamber 2. When the vacuum pump is started, negative pressure can be quickly generated in the adsorption disk 8, thereby quickly adsorbing and transporting the product, thereby increasing the overall transportation speed.

[0032] See also Figure 4 and Figure 5 The blocking mechanism 6 includes an array of fixed rods 12 fixedly connected to the inner wall of the fixed tube 7, the end of the fixed rod 12 away from the inner wall of the fixed tube 7 is fixedly connected to a sliding sleeve 13, and a sliding rod 14 is slidably connected in the sliding sleeve 13, and the end of the sliding rod 14 close to the push rod 19 is fixedly connected to an abutment block 15, and a groove 16 is provided on the outer wall of the abutment block 15 close to the rolling ball 20, and the end of the sliding rod 14 away from the abutment block 15 is fixedly connected to a blocking ball 17, and the blocking ball 17 is located in the connecting sleeve 11, and the inner wall of the adsorption plate 8 close to the abutment block 15 is fixedly connected to a fixing component 18 that fixes the abutment block 15.

[0033] See also Figure 5The fixing assembly 18 includes a pushing rod 19 fixedly connected to the inner wall of the adsorption plate 8 near the limit block 9, the pushing rod 19 is rotatably connected to the rolling ball 20 at one end away from the adsorption plate 8, the sliding plate 10 is fixedly connected to the mounting rod 21 at a position close to the rolling ball 20, the mounting rod 21 is slidably connected to the limit rod 22 at one end away from the sliding plate 10, the limit rod 22 is fixedly connected to the pushing block 23 at one end close to the rolling ball 20, a spring 24 is sleeved on the limit rod 22, one end of the spring 24 is fixedly connected to the pushing block 23, and the other end of the spring 24 is fixedly connected to the mounting rod 21.

[0034] In the initial state, under the action of its own gravity, the sealing ball 17 seals the connection sleeve 11 and the vacuum chamber 2. When carrying a relatively strong product, when the adsorption plate 8 moves to the product and contacts the surface of the product, the abutment block 15 contacts the surface of the product and causes the abutment block 15 to move. The movement of the abutment block 15 drives the sliding rod 14 to move, and the movement of the sliding rod 14 drives the sealing ball 17 to move, so that the sealing ball 17 no longer blocks the connection sleeve 11 and the vacuum chamber 2, so that the connection sleeve 11 and the vacuum chamber 2 are connected, and negative pressure is generated in the adsorption plate 8 to adsorb the product. At the same time, when the adsorption plate 8 moves, the adsorption plate 8 drives the pushing rod 19 to move, and the movement of the pushing rod 19 drives the rolling ball 20 to move. The rolling ball 20 abuts against the pushing block 23 and drives the pushing block 23 to overcome the The elastic force of the spring 24 abuts against the movement of the contact block 15, and the movement of the pushing block 23 drives the limiting rod 22 to move, so that the other end of the limiting rod 22 enters the slot 16, so that the vacuum chamber 2 remains connected with the adsorption plate 8 to carry the product. When carrying heavier products, the adsorption plate 8 moves downward under the gravity of the product, and the movement of the adsorption plate 8 drives the pushing block 23 to move downward, so that the rolling ball 20 is separated from the pushing block 23. Under the action of the spring 24, the limiting rod 22 is separated from the slot 16, so that the blocking ball 17 blocks the vacuum chamber 2 and the adsorption plate 8 under its own gravity. When the adsorption plate 8 descends, the space between the adsorption plate 8 and the sliding plate 10 becomes larger, thereby increasing the negative pressure in the adsorption plate 8, improving the adsorption force of the adsorption plate 8 on the product and preventing the product from falling.

[0035] See also Figure 5 One end of the limiting rod 22 extends into the slot 16 , so that the limiting rod 22 limits the abutment block 15 .

[0036] See also Figure 5 The 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] See also Figure 4The push rod 19 is arranged at an angle, and the distance between the push rod 19 and the sliding plate 10 gradually decreases from one end close to the adsorption disk 8 to the other end, so that the push rod 19 can drive the push block 23 to move through the rolling ball 20.

[0038] See also Figure 3 When the sealing ball 17 seals the connecting sleeve 11, the abutment block 15 is located in the adsorption disk 8, so that when the abutment block 15 contacts the product, the space between the adsorption disk 8 and the product is in a small state, and negative pressure that can stably adsorb the product can be quickly generated.

[0039] See also Figure 5 The diameter of the sliding sleeve 13 is smaller than the diameter of the fixed tube 7. There is a space between the sliding sleeve 13 and the fixed tube 7, so that the air in the adsorption disk 8 can be extracted through the space, and the negative pressure of the product in the adsorption disk 8 adsorbs the product.

[0040] See also Figure 4 The end of the connecting sleeve 11 away from the fixed tube 7 is in a trumpet shape, and can quickly connect the vacuum chamber 2 and the adsorption disk 8 when the blocking ball 17 moves.
