[0041] In the working process, the tube assembly machine is used to assemble the tube composed of a large plastic core, a white big head, a PVC inner tube, a soft small head and a small plastic core, and the feeding and discharging positions of the operator are both at the workbench 602.

[0042] When feeding, the operator places the tube in the lower clamping jaw 604, and the lower clamping jaw 604 is in a closed virtual gripping state, i.e., there is a gap around the lower clamping jaw 604 to accommodate the tube, the middle clamping jaw is automatically clamped after sensing the product, and then the upper clamping jaw is also clamped, and after the upper clamping jaw is clamped, it is rotated by 60° to enter the next assembly position.

[0043] The two vibration discs 3 of the next layer are respectively large plastic cores and white big head feeding positions, which are fed by the linear vibrator 605. The servo module 606 is started to drive the first lifting cylinder 607 and the clamping jaw cylinder 608 to grab the large plastic core for feeding. After receiving the large plastic core, the rear retracting cylinder 612 is retracted to move the large plastic core to below the shaping pipe. At the same time, the rodless cylinder 610 moves the feeding, so that the grabbing jaw 609 can put the white big head into the receiving jaw 611 after grabbing. When the two sets of fixtures of the bottom layer, i.e. the large plastic core and the white big head, are fed, they are immediately rotated to the next station for further assembly.

[0044] The inner tube jaw in the inner tube fixture 615 clamps the inner tube, the back cylinder is pressed down, the jaw is clamped by the additional spring, so that a certain clamping force is maintained on the rubber pipe surface. The inner tube fixture 615 has heating and blowing functions. The inner tube is softened by the heating rod 618, and is expanded by the blowing pipe joint 617.

The upper and lower module 702 is adjusted in height according to the length of the product to be produced after inputting the data, and the assembly height is automatically adjusted. This process is simultaneously operated with the two assembly mechanisms of the lower layer;

[0046] The inner tube placing wheel on the inner tube hanging rack 801 can wind and store the inner tube. When the inner tube is inserted, the inner tube is inserted from the tube insertion hole in the middle of the tube insertion plate 802. The tube insertion length is pre-set, and the corresponding program formula is adjusted. The 400W servo motor 1 803 is started to make the main gear 804 and the driven gear 805 move towards each other, so that the two sets of clamping wheels 806 can rotate and clamp the inner tube for conveying. At this time, the cutting cylinder 808 is retracted, the tube insertion is completed, the bottom is assembled at the same time, and after the assembly is completed, the servo motor 2 8131 is started to drive the two sets of belts 8132 to rotate, so that the shaping pipe rotates in both directions, and the large plastic core and the large white head assembled after the bottom are pulled into the shaping pipe. The height adjusting module 807 is started to drive it to lift upwards, so that the inner tube is extended for a distance. At this time, the upper clamping jaw clamps the inner tube, the cutting cylinder 808 is pushed out, so that the V-shaped cutter 810 on the cutter clamp 809 can extend into the cutter groove 812 in the cutter head 811, and then the inner tube is cut off. The height adjusting module 807 is further raised to the position, the tube insertion, assembly, clamping of the inner tube and cutting of the inner tube are completed at this station, and the small plastic core is rotated to the next station for assembly.

[0047] The start of the lead screw motor 902, so that the adjustment screw 903 can drive the lead screw slide 904 up and down, automatically adjust the height to adapt to different length of the pipe, and the swing arm motor 905 can drive the swing arm mechanism 910 to rotate, the swing arm mechanism 910 can grab the small plastic core to the assembly station, at this time, press down and assemble, reciprocating cylinder 906 reciprocating motion driven small plastic core rotation, let the pipe more easily, in the pipe at the same time through the air outlet 909 blow, make it quickly assemble, because the device inside the mechanism for rotating disc type operation, and the cylinder and sensor are followed by rotation, then all the gas and sensor power supply using air slip ring and electric slip ring connection, the device uses industrial computer and man-machine interface control.
