[0041] During operation, the shaped tube assembled by the inner tube assembly machine is composed of a large plastic core, a white large head, a PVC inner tube, a soft small head and a small plastic core. The operator's loading and unloading stations are both at workbench 602;

[0042] When loading, the operator puts the shaping tube into the lower clamp 604. At this time, the lower clamp 604 is in a closed and loose grip state, that is, there is a gap around the lower clamp 604 to accommodate the shaping tube. The middle clamp automatically clamps after sensing the product, and then the upper clamp also clamps the shaping tube. After the upper clamp is clamped, it rotates 60° and enters the next assembly station.

[0043] The two vibration plates 3 on the lower layer are respectively the feeding places of the large plastic core and the white big head. The linear vibrator 605 is used for feeding, and the servo module 606 is started to drive the first lifting cylinder 607 and the clamping cylinder 608 to grab the large plastic core for feeding. After receiving the large plastic core, the retracting cylinder 612 retracts to move the large plastic core to the bottom of the shaping tube. At the same time, the rodless cylinder 610 moves to feed the material, so that the grabbing clamp 609 can grab the white big head and put it into the receiving clamp 611. When the two sets of fixtures on the bottom layer, i.e. the large plastic core and the white big head, are loaded, they are immediately rotated to the next station for further assembly;

[0044] After the inner tube clamping claws in the inner tube fixture 615 clamp the inner tube, the cylinder on the back presses down, and the clamping claws are clamped with springs to maintain a certain clamping force on the hose surface. The inner tube fixture 615 has heating and blowing functions. The inner tube is softened by heating rod 618, and the inner tube is expanded by blowing through the blowing pipe joint 617. The downward-pressing cylinder clamping claws 616 clamp the inner tube and press it down to complete the preliminary assembly of the inner tube.

[0045] The upper and lower modules 702 drive the swing arm motion module 703 to rotate, and at the same time, the vacuum generator can stably grasp the soft small head on the linear vibrator 605, and then the swing arm motion module 703 continues to rotate to the assembly position, and the swing arm motion module 703 descends to press the soft small head. In order to adapt to different lengths of shaped tubes, the upper and lower modules 702 have a fixed height for discharging materials. The height of the upper and lower modules 702 is automatically adjusted according to the input data of the length of the product to be produced. This process is operated simultaneously with the two assembly mechanisms on the lower layer;

[0046] The inner tube placement wheel on the inner tube incoming hanger 801 can roll up and store the inner tube. When threading the inner tube, thread the tube from the tube threading port opened in the middle of the tube threading plate 802. The threading length is preset, and the corresponding program formula is called out. The 400W servo motor 1 803 is started to make the main gear 804 and the slave gear 805 move towards each other, so that the two sets of clamping wheels 806 can rotate and clamp the inner tube for transportation. At this time, the cylinder 808 is cut off and retracted, the tube threading is completed, and the bottom is assembled at the same time. After the assembly is completed, the servo motor 2 8131 is started to drive the two sets of belts 813 2 is rotated, so that the shaping tube rotates forward and backward, and the large plastic core and the large white head assembled at the bottom are pulled into the shaping tube at the same time, and the height adjustment module 807 is started to drive it to lift upward, and the inner tube is extended for a distance. At this time, the upper clamping claw clamps the inner tube, and the cutting cylinder 808 is pushed out, so that the V-shaped cutter 810 on the blade clamp 809 can extend into the knife groove 812 opened inside the cutter head 811, and then the inner tube is cut off. The height adjustment module 807 rises to its position again, and the tube threading, assembly, clamping of the inner tube by the clamping claw, and cutting of the inner tube are completed at this station, and the small plastic core is rotated to the next station to be assembled;

[0047] Start the screw motor 902, so that the adjustment screw 903 can drive the screw slide 904 to move up and down, and automatically adjust the height to adapt to different lengths of the shaped tubes, 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, and then pressurize it downward for assembly. When pressurized, the reciprocating cylinder 906 reciprocates to drive the small plastic core to rotate, making it easier to thread the tube. While threading the tube, blow air through the air outlet 909 to quickly assemble it. Since the internal mechanism of the device is a turntable operation, and the cylinder and the sensor rotate with it, all air sources and sensor power supplies are connected by air slip rings and electric slip rings. This equipment is controlled by an industrial computer and a human-machine interface.

[0048] Through the above steps, the inner tube assembly machine can realize a series of operations such as automatic grasping, positioning, assembly and transportation of the inner tube of the shaped tube and the seal by setting the bottom assembly mechanism, the upper assembly mechanism, the inner tube assembly mechanism and the small plastic core assembly mechanism. This greatly improves the degree of automation of assembly and reduces manual intervention to solve the problem that traditional inner tube assembly machines use manual assembly, which is time-consuming and labor-intensive and has uncontrollable efficiency.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
