[0027] Example 1

[0028] like Figure 1As shown, a suction cup mechanism for an automatic production line includes a first mounting plate 2, a second mounting plate 3, a cylinder group, a suction cup assembly 5 and a buffer 11. The cylinder group includes a large-diameter open clamp cylinder, a rodless cylinder and an ultra-thin cylinder. The large-diameter open clamp cylinder is fixedly connected to the suction cup assembly 5 through the first mounting plate 2. The large-diameter open clamp cylinder is vertically mounted on the fixed seat assembly 12 and is connected to the rodless cylinder through the fixed seat assembly 12; the ultra-thin cylinder is fixed to the bottom of the rodless cylinder through the second mounting plate 3; the suction cup assembly 5 includes an upper suction cup mounting plate 51, an upper suction cup 52, a lower suction cup 53, and a lower suction cup mounting plate 54 arranged in sequence from top to bottom; the buffer 11 is mounted on the frame.

[0029] In this embodiment, the large-diameter open clamp cylinder adopts the HFT large-diameter open clamp cylinder 4, which can clamp and position the cloth cover quickly and accurately. A cylinder fixing plate 13 is provided at the bottom of the HFT large-diameter open clamp cylinder 4. The cylinder fixing plate 13 is fixedly connected to the fixed seat assembly 12, and the suction cup assembly 5 is fixed by the upper and lower first mounting plates 2 and the support plate. The HFT large-diameter open clamp cylinder 4 is installed vertically, which can provide a stable clamping force to ensure the stability of the cloth cover in the vertical direction during the clamping process, thereby ensuring that the cloth cover is smoothly opened and avoiding the cloth cover from sliding or falling off due to insufficient clamping force.

[0030] like Figure 1 and Figure 3 As shown, the upper suction cup mounting plate 51, the upper suction cup 52, the lower suction cup 53, and the lower suction cup mounting plate 54 are all in the shape of a rectangular parallelepiped. The upper suction cup mounting plate 51 is the same size as the upper suction cup 52, and the lower suction cup 53 is longer than the lower suction cup mounting plate 54. The upper suction cup mounting plate 51, the upper suction cup 52, the lower suction cup 53 and the lower suction cup mounting plate 54 are installed in sequence from top to bottom, and the center points of the upper suction cup mounting plate 51, the upper suction cup 52, the lower suction cup 53 and the lower suction cup mounting plate 54 are on the same vertical line to ensure that the cloth cover is accurately positioned; as shown Figure 3 and Figure 4 As shown, multiple cylindrical suction cups 55 are provided inside the upper suction cup 52 and the lower suction cup 53. The suction cups 55 inside the upper suction cup 52 and the lower suction cup 53 are staggered with each other, so that the suction cloth cover is more secure.

[0031] like Figure 2As shown, the RMT rodless cylinder 7 moves forward on the guide rail 82 through the slider 81 below, the HFT large-diameter opening clamp cylinder 4 opens, and the cloth sleeve pulling mechanism clamps the cloth sleeve and places the cloth sleeve on the lower suction cup 53. At this time, the cloth sleeve pulling mechanism automatically retracts, and the HFT large-diameter opening clamp cylinder 4 clamps the cloth sleeve, driving the suction cup assembly 5 to move, the upper suction cup 52 sucks the upper part of the cloth sleeve, and the lower suction cup 53 sucks the bottom of the cloth sleeve. The HFT large-diameter opening clamp cylinder 4 opens, and the cloth sleeve is stretched open by the upper and lower suction cups. The RMT rodless cylinder 7 moves backward through the slider 81 and the guide rail 82, and the SDA ultra-thin cylinder 9 retracts to transport the stretched cloth sleeve to the stretching mechanism. The upper and lower suction cups release the cloth sleeve at the same time, and the stretching mechanism tightens the cloth sleeve. The SDA ultra-thin cylinder 9 extends, driving the suction cup mechanism 1 back to its original position, and this action cycle is completed to complete the automatic opening and delivery of the cloth sleeve, which greatly saves labor and improves production efficiency and production safety.

[0032] Example 2

[0033] like Figure 1 As shown, a suction cup mechanism for an automatic production line includes a first mounting plate 2, a second mounting plate 3, a cylinder group, a suction cup assembly 5 and a buffer 11. The cylinder group includes a large-diameter open clamp cylinder, a rodless cylinder and an ultra-thin cylinder. The large-diameter open clamp cylinder is fixedly connected to the suction cup assembly 5 through the first mounting plate 2. The large-diameter open clamp cylinder is vertically mounted on the fixed seat assembly 12 and is connected to the rodless cylinder through the fixed seat assembly 12; the ultra-thin cylinder is fixed to the bottom of the rodless cylinder through the second mounting plate 3; the suction cup assembly 5 includes an upper suction cup mounting plate 51, an upper suction cup 52, a lower suction cup 53, and a lower suction cup mounting plate 54 arranged in sequence from top to bottom; the buffer 11 is mounted on the frame.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, the rodless cylinder used is an RMT rodless cylinder 7, and a sliding assembly 8 is provided below the left and right sides of the RMT rodless cylinder 7. The linear motion of the rodless cylinder is realized through the sliders 81 and guide rails 82 on both sides, and the cloth cover is automatically transported; a buffer 11 is installed next to each of the two side guide rails, and a fixed seat is installed at the bottom of the buffer 11. The buffer 11 is symmetrically arranged. The buffer 11 can enable the suction cup mechanism 1 to play a buffering role during the transportation process, and at the same time protect the equipment and the cloth cover from damage.

[0035] Automatic cloth cover delivery is achieved by cooperating with the sliding assembly 8 and the RMT rodless cylinder 7. The RMT rodless cylinder 7 can provide smooth and uniform movement to ensure that the cloth cover will not be affected by the vibration of the equipment, and can ensure linear movement to save space.

[0036] Example 3

[0037] like Figure 1 Figure 1 shows a suction cup mechanism for an automated production line. In this embodiment, the ultra-thin cylinder is an SDA ultra-thin cylinder 9, secured to a cylinder mounting plate 13. A floating joint 10 is provided at one end of the piston rod of the SDA ultra-thin cylinder 9, which is fixedly connected to a second mounting plate 3. The SDA ultra-thin cylinder 9 is connected to the cylinder mounting plate 13 using a flush mounting method, saving space. The cloth cover is then fed onto the opening mechanism 1, and the SDA ultra-thin cylinder 9 opens, driving the entire suction cup mechanism 1 backwards via the piston rod to its original position, awaiting the next action.

[0038] The SDA ultra-thin cylinder 9 used in the suction cup mechanism 1 in this example can reduce noise, save space, and improve the positioning accuracy of the suction cup mechanism 1. Preferably, other cylinders that meet the requirements, such as SMC ultra-thin cylinders, can also be used.

[0039] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
