In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, other steps or units inherent to the process, method, system, product or equipment containing a series of steps or units.

[0027] 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.

[0028] First embodiment:

[0029] A cotton rod vacuum suction device, such as Figures 1 to 3As shown, comprising a vacuum suction body 1, the vacuum suction body 1 is provided with one or more vacuum suction pipes 2, the vacuum suction pipe 2 has a suction channel 3, the suction channel 3 at least includes a limiting section 302 and a containing section 301 connected in communication, the limiting section 302 is located above the containing section 301, the length of the containing section 301 is greater than or equal to the length of the cotton rod 12, the vacuum suction pipe 2 can completely suck the cotton rod 12 into the suction channel 3, and the head of the cotton rod 12 is attached to the bottom of the limiting section 302, so that the cotton rod 12 cannot be extended and is uniformly limited at the bottom of the limiting section 302.

[0030] In this embodiment, the length of the containing section 301 is greater than the length of the cotton rod 12, so that when the cotton rod 12 is completely sucked into the containing section 301, the cotton rod 12 can be directly inserted into the oil groove to align the installation position, without worrying about the problem of misalignment of the bottom of the cotton rod 12, thereby greatly improving the accuracy and success rate of installation. And the suction channel 3 can also play a role in guiding the cotton rod 12, so that the originally curved cotton rod 12 is forced to adjust to a straight state in the suction channel 3, further ensuring the smooth progress of subsequent installation.

[0031] The suction channel 3 is arranged in the vertical direction, and the limiting section 302 and the containing section 301 are both cylindrical and coaxially arranged. The diameter of the limiting section 302 is smaller than the diameter of the head of the cotton rod 12, so that the head of the cotton rod 12 is attached to the bottom of the limiting section 302 and cannot continue to penetrate. The diameter of the containing section 301 is greater than the diameter of the head of the cotton rod 12, so that the cotton rod 12 can enter the containing section 301, and the diameter of the containing section 301 is only slightly larger than the diameter of the head of the cotton rod 12, so that the cotton rod 12 can maintain a vertical state in the containing section 301, thereby guiding the cotton rod 12.

[0032] The bottom of the containing section 301 is provided with a flared mouth 4, the diameter of the flared mouth 4 gradually increases from top to bottom, the top of the flared mouth 4, i.e. the smallest diameter, is the same as the diameter of the containing section 301, and the flared mouth 4 makes it easier for the cotton rod 12 to enter the suction channel 3 and not to be stuck.

[0033] The vacuum suction pipe 2 is arranged in the vertical direction, and the vacuum suction pipe 2 includes an upper section 201 and a lower section 202, both of which are cylindrical and coaxially arranged, and the diameter of the lower section 202 is smaller than that of the upper section 201, wherein the diameters of the upper section 201 and the lower section 202 only affect the thickness of the circumferential wall of the vacuum suction pipe 2, and are irrelevant to the diameter of the suction channel 3 inside. By setting the lower section 202 to be thinner, it is convenient for the vacuum suction pipe 2 to extend into the oil groove when installing the cotton rod 12.

[0034] The joint of the upper section 201 and the lower section 202 is conical, the smaller end of the conical shape is downward, the diameter of the smaller end is the same as that of the lower section 202, and the diameter of the larger end is the same as that of the upper section 201. By setting the joint as a conical shape, the size is gradually increased, and when the distance of the lower section 202 extending into the oil tank deviates, the oil tank is not easy to be damaged.

[0035] The vacuum suction body 1 comprises a mounting frame 101, the bottom of the mounting frame 101 is fixed with a mounting plate 102, and the vacuum suction pipe 2 is fixed on the mounting plate 102 and penetrates downward below the mounting plate 102 in the vertical direction. In the embodiment, the vacuum suction pipe 2 is provided with a root, and 5 cotton rods 12 can be grabbed at the same time, and the 5 vacuum suction pipes 2 are arranged equidistantly and spaced apart in the horizontal direction on the mounting plate 102. The mounting frame 101 is connected to the driving mechanism in the lighter assembly equipment, and the driving mechanism drives the vacuum suction body 1 to move in space.

[0036] Second embodiment:

[0037] A cotton rod mounting mechanism, as shown in Figure 4 , comprises a vibrating feeding disc 5 and a feeding table 6, and also comprises the cotton rod vacuum suction device described in the above embodiment. The vibrating feeding disc 5 delivers the cotton rod 12 to the feeding table 6, and the cotton rod vacuum suction device grabs the cotton rod 12 from the feeding table 6 and loads it into the oil tank.

[0038] As shown in Figure 5 and Figure 6 , the feeding plate 8 is slidably connected to the feeding table 6, the guide rail 11 and the driving cylinder 10 are fixed on the feeding plate 8, a sliding block is driven to move on the guide rail 11 by the output shaft of the driving cylinder 10, and the feeding plate 8 is fixed on the sliding block, so that the driving cylinder 10 can drive the feeding plate 8 to slide along the guide rail 11.

[0039] The side wall of the feeding plate 8 is attached to the discharge channel 7 of the vibrating feeding disc 5, the feeding plate 8 moves in the horizontal direction, and the moving direction is perpendicular to the conveying direction of the discharge channel 7, a containing groove 9 is formed on the side of the feeding plate 8 facing the discharge channel 7, one containing groove 9 is used to contain one cotton rod 12, and five containing grooves 9 are formed on the feeding plate 8, corresponding to the five vacuum suction pipes 2, and five cotton rods 12 can be supplied at one time.

[0040] The cotton rod 12 is vertically arranged in the discharge channel 7 for conveying, so the containing groove 9 is also vertically formed and penetrates through the upper and lower sides of the feeding plate 8. The top of the containing groove 9 is provided with a limiting part, the opening of the limiting part gradually decreases from top to bottom, so that the head of the cotton rod 12 can be clamped in the limiting part, and the cotton rod 12 will not fall downward.

[0041] When the discharge channel 7 is not aligned with the containing groove 9, the last row of cotton rods 12 in the discharge channel 7 is in contact with the side wall of the feeding plate 8, so that the cotton rods 12 will not fall out; when the driving cylinder 10 drives the feeding plate to move to the position where the containing groove 9 is aligned with the discharge channel 7, the last row of cotton rods 12 in the discharge channel 7 will move into the containing groove 9.

[0042] After the cotton rods 12 enter the containing groove 9, the driving cylinder 10 drives the feeding plate to move to the right, so that the containing groove 9 is again misaligned with the discharge channel 7; at this time, the cotton rod vacuum suction device takes away the cotton rods 12 in the containing groove 9, and then the driving cylinder 10 again aligns the containing groove 9 of the feeding plate with the discharge channel 7, so that the next row of cotton rods 12 enters the containing groove 9, and the feeding is repeated.
