[0027] The utility model is described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] The nuclear pore membrane gas regulating valve assembly production line is a production line used to automatically assemble the components of the nuclear pore membrane gas regulating valve (base, nuclear pore membrane and fasteners). The assembly processes involved mainly include base assembly, film coating, fastener assembly and whole piece unloading. Figure 1 As shown, the basic module of the nuclear pore membrane gas regulating valve assembly production line includes a double-speed chain body 100, a bottom assembly mechanism 200, a film cutting and laminating mechanism 300, a fastener assembly mechanism 400, a whole piece unloading mechanism 500, and a pallet 600 carried and transported by the double-speed chain body 100 and moving between the above-mentioned mechanism stations, which are sequentially arranged on the double-speed chain body 100 based on the assembly process.

[0030] The tray 600 is used as a carrier to accommodate and position the nuclear pore membrane gas regulating valve assembly, and at the same time, the nuclear pore membrane gas regulating valve assembly is driven by the double-speed chain body 100 to realize the transfer and replacement of the nuclear pore membrane gas regulating valve assembly between different stations. Figure 2 As shown, the upper surface of the tray 600 is provided with a plurality of cavities 601, which are adapted to the structure of the bottom piece and the fastener. In this example, the number of cavities 601 is two rows of 8 cavities each, for a total of 16, that is, one tray 600 can assemble 16 products at the same time. At the same time, a locking spring 602 is provided on the periphery of the cavity 601 to clamp and fix the components in the cavity 601.

[0031] This embodiment relates to a film cutting and laminating mechanism 300 assembled on a nuclear pore membrane gas regulating valve assembly production line, such as Figure 3 As shown, the film cutting and coating mechanism 300 is arranged on the nuclear pore membrane gas regulating valve assembly production line through a stand 310, and is responsible for cutting and forming the nuclear pore membrane and coating it on the upper surface of the bottom piece in the tray cavity 601. Its main functional modules include a lifting assembly 320, an unwinding roller group 330, a winding roller group 340, a winding roller group 350, a flattening roller group 360 and a laser film cutting machine 370.

[0032] The specific structure of the film cutting and laminating mechanism 300 is introduced in detail below:

[0033] The stand 310 is used as the mounting base of the entire mechanism and is disposed on both sides of the speed chain body 100. Figure 4 As shown, it includes two side panels 311 and a bottom plate 313 located between the two side panels 311, and the bottom plate 313 is located below the double-speed chain line body 100; vertical plates 312 serving as the installation base of the roller group are installed facing each other between the two side panels 311, and film cutting machine brackets 314 for installing the laser film cutting machine 370 are respectively mounted on the two side panels 311.

[0034] like Figure 5 As shown, the lifting assembly 320 includes a lifting cylinder 321 installed at the bottom of the base plate 313 and a lifting plate 322 connected to the upward output of the lifting cylinder 321 and located above the base plate 313, and a pair of positioning columns 323 are installed on the lifting plate 322, and the positioning columns 323 are used to be plugged and adapted with the positioning holes at the bottom of the tray 600.

[0035] like Figure 5 As shown, the unwinding roller group 330, the winding roller group 350, the rewinding roller group 340 and the flattening roller group 360 are arranged between the two vertical plates 312, and a horizontal support plate 312a is provided between the two vertical plates 312. The unwinding roller group 330 is used to support the unwinding roller; the winding roller group 350 is used to spread the nuclear pore membrane on the unwinding roller and transport it to the film cutting and laminating station along a certain track; the rewinding roller group 340 is used to rewind and recycle the nuclear pore membrane after the film cutting and laminating.

[0036] like Figure 5 As shown, the unwinding roller set 330 is composed of a pair of juxtaposed and parallel rollers, and the upper part of the two rollers constitutes a supporting space for placing the unwinding rollers.

[0037] like Figure 5 As shown, the winding roller group 350 includes a first spreading roller 351 and a second spreading roller 352 disposed on the left and right sides above the unwinding roller group 330, a first winding roller 353 located on the upper right of the second spreading roller 352, and a second winding roller 354, a third winding roller 355, and a fourth winding roller 356 arranged in a staggered manner below the first roller 331 and the second roller 332. The nuclear pore membrane on the unwinding roller first enters the first winding roller 353 through the two spreading rollers above, and then winds downward from the first winding roller 353 to the second winding roller 354, the third winding roller 355, and the fourth winding roller 356, and finally spreads horizontally below the flattening roller group 360.

[0038] like Figure 5As shown, the flattening roller group 360 is composed of a plurality of horizontally juxtaposed pressure rollers, and its function is to cooperate with the lifting assembly 320 below to spread and press the upper surface of the nuclear pore membrane.

[0039] like Figure 5 As shown, the winding roller group 340 includes a first transfer roller 341 driven by a winding motor, and the first transfer roller 341 is basically flush with the pressure roller of the flattening roller group 360. The winding roller group 340 also includes a winding roller 1 342 and a winding roller 2 343 arranged above the first transfer roller 341. The winding roller 1 342 is arranged below the winding roller 2 343 and receives the driving torque from the winding motor. The winding roller 2 343 is pressed against the top of the winding roller 1 342 by its own weight. When the winding motor drives the winding roller 1 342 to rotate, the winding roller 2 343 above it moves synchronously. Specifically, the two ends of the winding roller 2 343 are hung in the hanging grooves 344a opened in the hanging plates 344 on both sides through bearings, and the top of the hanging grooves 344a is an open channel, which provides a rising margin for the winding roller 2 343, that is, as the winding roller 1 342 below continues to wind, the diameter of the roller will gradually increase. At this time, the two ends of the winding roller 2 343 will be lifted up to a certain height along the open channel above the hanging grooves 344a to adapt to the changes of the winding roller 1 342 below.

[0040] The film cutting and laminating mechanism of this embodiment works as follows:

[0041] When the double-speed chain body 100 transports the tray carrying the bottom piece to the film cutting and laminating station, the lifting cylinder 321 pushes the lifting plate 322 to lift the tray 600 to the bottom of the spread-out nuclear pore membrane, and the top of the nuclear pore membrane is pressed by the flattening roller group 360, and then the laser film cutting machine 370 starts film cutting, cutting out the same number of circular membrane pieces as the bottom piece below from the whole nuclear pore membrane, and pressing them on the top of the bottom piece. After the film cutting is completed, the winding motor drives the winding roller group 340 to recycle the used nuclear pore membrane.
