[0025] Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0026] First embodiment:

[0027] A cotton sheet vacuum suction device, such as Figure 1 and Figure 2 As shown, comprising a vacuum suction body 1, one or more vacuum suction pipes 2 are movably arranged on the vacuum suction body 1, the vacuum suction pipe 2 moves along the vertical direction, a sleeve 3 is vertically arranged on the vacuum suction body 1, the vacuum suction pipe 2 penetrates into the sleeve 3 and slides up and down along the sleeve 3, and the vacuum suction pipe 2 can extend from the bottom of the sleeve 3.

[0028] The sleeve 3 and the vacuum suction pipe 2 are both cylindrical and coaxially arranged, the inner diameter of the sleeve 3 is larger than the diameter of the cotton sheet 10, so that when the vacuum suction pipe 2 is retracted into the sleeve 3, the cotton sheet 10 can be put into the sleeve 3 at the same time, and the inner diameter of the sleeve 3 is only slightly larger than the diameter of the cotton sheet 10, which can guide the cotton sheet 10 and keep the cotton sheet 10 in the center position of the vacuum suction pipe 2. The inner diameter of the vacuum suction pipe 2 is smaller than the diameter of the cotton sheet 10, so that when the vacuum suction pipe 2 sucks the cotton sheet 10, the cotton sheet 10 is prevented from entering the vacuum suction pipe 2.

[0029] The bottom of the sleeve 3 is provided with a flared mouth 4, the inner diameter of the flared mouth 4 gradually increases from top to bottom, the inner diameter of the top end of the flared mouth 4 is the same as that of the sleeve 3, and the flared mouth 4 can facilitate the cotton sheet 10 to enter the sleeve 3 and prevent the cotton sheet 10 from being stuck at the opening of the sleeve 3.

[0030] The vacuum suction body 1 is provided with one or more lifting cylinders 5, and the lifting cylinders 5 correspond to the vacuum suction pipes 2 one by one. In the embodiment, the vacuum suction pipes 2 are provided with five, and five cotton sheets 10 can be clamped at the same time. The lifting cylinders 5 are correspondingly provided with five. In other embodiments, only one lifting cylinder 5 can be provided, and a connecting plate is arranged on the piston rod of the lifting cylinder 5. Five vacuum suction pipes 2 are fixed on the connecting plate, and one lifting cylinder 5 drives five vacuum suction pipes 2 to move through the connecting plate. The lifting cylinder 5 is vertically arranged, and the piston rod faces downward. The vacuum suction pipe 2 is fixed on the piston rod of the lifting cylinder 5.

[0031] The vacuum suction body 1 includes a mounting frame 101, and the lifting cylinder 5 is fixed on the mounting frame 101. An installation plate 102 is fixed on the mounting frame 101 and below the lifting cylinder 5. The installation plate 102 is horizontally arranged, the sleeve 3 is fixed on the installation plate 102 and penetrates downward below the installation plate 102 in the vertical direction. Five sleeves 3 are correspondingly arranged on the installation plate 102, and the five sleeves 3 are equidistantly arranged on the installation plate 102. The mounting frame 101 is connected to a driving mechanism in a lighter assembly equipment, and the vacuum suction body 1 is driven to move in space by the driving mechanism.

[0032] The upper end surface of the installation plate 102 is provided with a limiting block 6, which is used to limit the movement stroke of the vacuum suction pipe 2. The head of the vacuum suction pipe 2 has a protruding device 7. When the lifting cylinder 5 drives the vacuum suction pipe 2 to move downward to a predetermined position, the head of the vacuum suction pipe 2 will be in close contact with the limiting block 6, so that the vacuum suction pipe 2 cannot continue to stretch out downward, thereby achieving the stroke limiting effect, and further improving the accuracy of the installation of the cotton sheet 10.

[0033] The limiting block 6 is a bolt, which is vertically arranged and threadedly connected with the upper end surface of the installation plate 102. The limiting block 6 can be rotated to different heights to adapt to different extension stroke distances of different types of oil tanks.

[0034] In the embodiment, the extension stroke of the lifting cylinder 5 and the length of the vacuum suction pipe 2 have the following relationship. When the piston rod of the lifting cylinder 5 is completely retracted, the bottom end of the vacuum suction pipe 2 is located in the sleeve 3, and the vacuum suction pipe 2 will not completely come out of the sleeve 3 upward, so that the sliding of the vacuum suction pipe 2 is smoother, and the vacuum suction pipe 2 is prevented from being stuck.

[0035] After the vacuum suction pipe 2 sucks the cotton sheet 10, the vacuum suction pipe 2 first drives the cotton sheet 10 to retract into the sleeve 3, and then the cotton sheet 10 clamping jaw moves. During the movement process, the cotton sheet 10 is located in the sleeve 3, so that the cotton sheet 10 is not easy to fall off, and has a guiding effect on the cotton sheet 10. After moving to the installation position, the lifting cylinder 5 drives the vacuum suction pipe 2 to stretch out downward until the cotton sheet 10 reaches the installation position, and then the cotton sheet 10 is released. The cotton sheet 10 will not be turned over at all.

[0036] Second embodiment:

[0037] A cotton sheet mounting mechanism, as shown in Figure 3 includes a vibrating loading tray 8 and a loading table 9, and the cotton sheet vacuum suction device described in the above embodiments. The vibrating loading tray 8 delivers the cotton sheet 10 to the loading table 9 through a straight vibrating channel 11, and the cotton sheet vacuum suction device then grabs and mounts the cotton sheet 10 into the oil groove from the loading table 9.

[0038] Those skilled in the art should understand that the above discussion of any of the embodiments is only exemplary and is not intended to imply that the scope (including claims) of the embodiments disclosed by the present application is limited to these examples; under the idea of the embodiments of the present application, the above embodiments or technical features in different embodiments can also be combined, and there are many other changes of different aspects of the embodiments of the present application as above.
