In the working process of the invention, the clamping and transferring component clamps the cut zipper to move and enables the zipper to pass through the zipper head penetrating unit 2 and the upper stopping unit 3 in sequence; when the zipper moves to the position of the zipper head penetrating unit 2, the zipper head penetrating unit 2 carries out a head penetrating process and installs the zipper head on the zipper; when the zipper moves to the position of the upper stop unit 3, the upper stop unit 3 performs an upper stop process, and upper stops are formed on the left zipper belt and the right zipper belt of the zipper respectively.

In the process of performing upper stop forming processing by the upper stop unit 3, when the zipper entering the upper stop unit 3 is a front penetrating zipper, the monofilament supply assembly 37 on the left side supplies the monofilament to the upper left stop forming position of the front penetrating zipper, and the monofilament supply assembly 37 on the right side supplies the monofilament to the upper right stop forming position of the front penetrating zipper; when the ultrasonic transducer 33 is started and the upper stop ultrasonic welding molding is carried out, the monofilaments in the left upper stop molding position of the zipper which is being penetrated are welded to the left chain belt of the zipper which is being penetrated, and the monofilaments in the right upper stop molding position of the zipper which is being penetrated are welded to the right chain belt of the zipper which is being penetrated. When the zipper entering the upper stop unit 3 position is a reverse-through zipper, the switching driving mechanism acts and drives the two monofilament supply assemblies 37 to switch and move, so that each monofilament supply assembly 37 is respectively aligned with the corresponding upper stop forming position of the reverse-through zipper, the monofilament supply assembly 37 on the left side supplies the monofilament to the upper left stop forming position of the reverse-through zipper, and the monofilament supply assembly 37 on the right side supplies the monofilament to the upper right stop forming position of the reverse-through zipper; when the ultrasonic transducer 33 is started and the upper stop ultrasonic welding molding is carried out, the monofilaments in the left upper stop molding position of the reverse-through zipper are welded to the left chain belt of the reverse-through zipper, and the monofilaments in the right upper stop molding position of the reverse-through zipper are welded to the right chain belt of the reverse-through zipper.

In the process of the upper stop welding and forming, the movable frame driving cylinder 322 drives the lifting movable frame 321 to move up to the upper limit position, so that the monofilaments of the monofilament supply assembly 37 can be accurately supplied to the upper stop forming position; when the monofilament enters the upper stop forming position, the movable frame driving cylinder 322 drives the lifting movable frame 321 to move down to the lower limit position, so that the zipper can accurately penetrate into the upper stop forming position. When the monofilament enters the upper stop forming station and is subjected to ultrasonic welding, the front welding lower die 351 or the rear welding lower die 352 at the upper stop forming station is closed with the upper welding die 34, and after the upper stop ultrasonic welding is completed, the front lower die driving mechanism 361 or the rear lower die driving mechanism 362 drives the corresponding front welding lower die 351 and the corresponding rear welding lower die 352 to move downwards, so that the zipper formed at the upper stop can be smoothly moved away from the upper stop unit 3 through the clamping and transferring unit 1.

From the above situation, it can be known that, through the above structural design, the zipper slider and the upper stop device of the invention can be simultaneously applied to the upper stop processing operation of the forward and backward zipper, i.e. the zipper slider and the upper stop device of the invention have the advantages of novel structural design, high automation degree, strong adaptability and high flexible manufacturing degree.
