DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] Depend on Figures 1 to 3 As shown, a flexible assembly line for vacuum bottles includes a conveyor device 1, a bottom sealing device 2, and an airtightness detection device 3. The conveyor device 1 includes a front conveyor belt 12 and a rear conveyor belt 13. The front conveyor belt 12 for conveying the bottle body 4 passes through the bottom sealing device 2, and the rear conveyor belt 13 passes through the airtightness detection device 3 and the bottom sealing device 2. The rear conveyor belt 13 is arranged parallel to the front conveyor belt 12. The front conveyor belt 12 includes an outer fixing belt 11 and a fixing bracket 14. The fixing bracket 14 with an adjustable clamping range is installed between the outer fixing belts 11. The bottle body 4 is conveyed. The front conveyor belt 12 and the rear conveyor belt 13 have the same structure. The rear conveyor belt 13 is used to convey the product after the bottom 5 and the bottle body 4 are glued together into the airtightness detection device 3 for airtightness testing.

[0025] The fixed bracket 14 includes an outer ring 141, a sliding ring 142 and a sliding plate. The sliding plates are in six groups and are fixedly mounted on the outer ring 141. The sliding plates include a baffle 143, a limiting groove 144 and a rotating shaft 145. The baffle 143 is mounted on the outer ring 141 via the rotating shaft 145. The limiting groove 144 on the baffle 143 cooperates with the protrusion on the sliding ring 142. After the sliding ring 142 rotates, the clamping range of the sliding plate is changed, thereby adapting to the sizes of vacuum bottles of different models and facilitating the transportation of the bottle body 4.

[0026] Example 2

[0027] like Figures 1 to 6As shown, in this embodiment, the bottom sealing device 2 includes a bottle body clamping device 21, a bottle bottom clamping device 22, a push rod 23 and a glue dispensing device 24. The other structures of Example 2 are the same as those of Example 1. The bottle body clamping device 21 is installed above the front conveyor belt 12, and the push rod 23 is installed below the bottle body clamping device 21. The bottle body clamping device 21 grabs and clamps the bottle body 4 from the front conveyor belt 12. The bottle bottom clamping device 22 and the glue dispensing device 24 are located beside the conveyor belt 12. The bottle bottom clamping device 22 clamps the bottle bottom 5 and moves it to the top of the glue dispensing device 24. After glue is dispensed, the bottle bottom 5 moves to the bottom of the bottle body clamping device 21. Under the cooperation of the bottle body clamping device 21, the bottle bottom clamping device 22 and the hydraulic push rod 23, the bottle bottom 5 is combined with the bottle body 4.

[0028] The bottle body clamping device 21 includes a conveyor belt 211 and a first clamp 212. Multiple groups of first clamps 212 are installed on the conveyor belt 211. The first clamp 212 is a mechanical clamping arm of the prior art, and the clamping size can be automatically changed. The bottle bottom clamping device 22 includes a clamping device rotating shaft 221 and a second clamp 222. The number of the second clamps 222 is six and they are installed on the clamping device rotating shaft 221.

[0029] The dispensing device 24 includes a fixed base 241, a rotating shaft 242, a rotating joint 243, an electric push rod 244 and a glue injection head 245. The rotating shaft 242 is mounted on the fixed base 241, the rotating joint 243 is provided on the top of the rotating shaft 242, the electric push rod 244 is mounted on the rotating shaft 242, and the glue injection head 245 is provided on the top of the electric push rod 244.

[0030] One end of the rotary joint 243 supplies glue to the glue injection head 245 through the glue hose provided on the electric push rod 244, and the other end of the rotary joint 243 is connected to the glue storage tank provided at the bottom of the glue dispensing device 24 through the glue hose provided inside the rotating shaft 242. The glue injection head 245 changes the length of rotation under the push of the electric push rod 244. Since the bottom diameters of vacuum bottles of different specifications are different, the vacuum bottle flexible assembly line adopts a glue dispensing device 24 with automatic adjustment function during the processing. The length of the electric push rod 244 is adjusted on the main control device to adapt to the production needs of vacuum bottles of different specifications, thereby improving the production efficiency of the equipment, making the equipment highly adaptable in production, and reducing the trouble of replacing equipment modules.

[0031] To sum up, the working principle of the present invention is: a flexible assembly line for vacuum bottles can effectively clamp and fix the bottle body 4 with the help of a fixed bracket 14 provided on the conveying device 1. The fixed bracket 14 has an autonomous adjustment function and can also meet the fixing work of bottle bodies 4 with different diameters. During the gluing process, a dispensing device 24 with an adjustment function is used. The dispensing device 24 can automatically adjust the dispensing position, so that the flexible assembly line for vacuum bottles can produce vacuum bottles of more specifications, improve production efficiency, and reduce equipment investment costs.

[0032] It should be noted that the first clamp 212, the second clamp 222 and the airtightness detection device 3 in this application are applications of existing technologies, and the fixed bracket 14 and the dispensing device 24 are the innovations of this application, which effectively solve the problem of low efficiency in the production switching process of vacuum bottles of different specifications.

[0033] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
