[0023] See also Figure 1-7 An embodiment of an automatic heat shrink tube sleeve machine for electronic detonator ignition elements comprises a machine platform 1, a material discharging rack 2 for placing bent continuous heat shrink tube coils is arranged on the adjacent side of the machine platform 1, N heat shrink tube coils 20 are placed on the material discharging rack 2, in this embodiment, the number of heat shrink tube coils 20 is 5, a tube pressing, pulling and cutting mechanism 3 for continuously feeding the tube forward and cutting it into small sections is arranged on the machine platform 1, a feeding mechanism 5 for transferring the arranged products to be sleeved (in this embodiment, the products to be sleeved are electronic detonator ignition elements, and heat shrink tubes need to be sleeved on one end of the electronic detonator ignition elements) is arranged on one side of the feeding mechanism 5, a tube taking, moving and sleeve mechanism 4 for taking away the small section and sleeveing ​​it on the electronic detonator ignition element is arranged on one side of the feeding mechanism 5, and a hot air blowing mechanism 6 is arranged on one side of the tube taking, moving and sleeve mechanism 4 for blowing hot air to shrink the heat shrink tube.

[0024] The tube pressing, pulling and cutting mechanism 3 includes a first frame 31, on which a tube feeding cylinder 32 is arranged, which is connected to a carrier platform 33 and can drive the carrier platform 33 to move forward and backward along the X-axis direction, a pressing block 35 is arranged on the upper side of the carrier platform 33, and a pressing block cylinder 36 installed on the carrier platform 33 drives the pressing block 35 to move up and down along the Z-axis direction, and five guide channels 34 for heat shrink tubes are arranged on the carrier platform 33, and five spring pressure rods 351 are arranged on the upper side of the guide channel 34, which are driven by a spring pressure rod cylinder 36 installed on the first frame 31. 52 drives the five spring pressure rods 351 to move up and down along the Z axis. A tube cutting cylinder 37 is provided at the upper end of the first frame 31. The tube cutting cylinder 37 drives a cutter 38 to move up and down along the Z axis. A lifting seat 39 is provided below the cutter 38. Five through holes are provided on the lifting seat 39. Five groups of optical fiber sensors are provided in the five through holes to detect and sense whether there is material leakage. The lifting seat 39 is driven by a lifting seat cylinder 391 installed on the first frame 31 to move up and down along the Z axis. The working principle is as follows: 5 heat shrink tubes are passed through the load-bearing In the guide channel 34 on the platform 33, in the initial state, the pressing block 35 presses down to press the five heat shrink tubes onto the bearing platform 33. At this time, the spring pressing rod 351 is in a loose state, and then the tube delivery cylinder 32 drives the bearing platform 33 and the compressed heat shrink tube to move forward along the X-axis direction to deliver the tube (pull the tube). The front end of the heat shrink tube extends into the five through holes of the lifting seat 39, and then the spring pressing rod cylinder 352 drives the five spring pressing rods 351 to press down along the Z-axis direction to press the five heat shrink tubes, and then the pressing block 35 rises, and the bearing platform 33 retreats back to the initial position; the spring pressing rod 35 The heat shrink tube is compressed to prevent it from shifting during subsequent cutting. Then, the tube cutting cylinder 37 drives the cutter 38 to move down along the Z-axis direction to cut off the front end of the heat shrink tube. The cut small segments of the heat shrink tube are retained in the five through holes of the lifting seat 39. Then, the lifting seat 39 moves down, and the tube removal and transfer sleeve mechanism 4 on the other side comes to take away the five small segments. Then, the lifting seat 39 rises and returns to the initial position. Then, the pressing block 35 is pressed down again, and the bearing platform 33 moves forward again to pull the tube, entering the next cycle, thus ensuring that the heat shrink tube is continuously fed forward (pulled) and cut.

[0025] The feeding mechanism 5 has two groups, each group includes a third frame 51, a linear slide along the Y-axis direction is installed on the third frame 51, a slide seat 52 is installed on the linear slide, a Y-axis linear driving element is arranged on one side of the linear slide, the slide seat 52 is connected to a card seat 53 for fixing the casing product (electronic detonator ignition element), and a plurality of card slots arranged in a linear array are arranged on the card seat 53. The Y-axis linear driving element includes a Y-axis motor 54 installed on the third frame 51, and the output shaft of the Y-axis motor 54 drives the connection A driving wheel 55 is connected to a driven wheel 56 through a belt 57. The driving wheel 55 and the driven wheel 56 are both rotatably set on the third frame 51. The belt 57 is connected to the slide 52. The working principle is: two groups of card seats 53 are alternately moved along the Y-axis direction to feed materials (electronic detonator ignition elements), one group is when the heat shrink tube is installed, and the other group is loading. The card seat with the heat shrink tube installed is moved to the hot air blowing mechanism 6, and hot air is blown to shrink the heat shrink tube. The two are performed alternately to improve the assembly efficiency.

[0026] The tube removal and transfer sleeve mechanism 4 includes a second frame, on which an X-axis linear module 41 is arranged, and the X-axis linear module 41 drives and connects an X-axis slide 42 to move back and forth along the X-axis direction, and a Z-axis driving element 43 is installed on the X-axis slide, and the Z-axis driving element 43 drives a Z-axis mounting seat 44 to move up and down along the Z-axis direction, and a rotation driving element 45 is arranged on the Z-axis mounting seat, and the rotation driving element 45 drives a vacuum suction seat 46 to rotate around the Y-axis direction, and the vacuum suction seat 46 is provided with N vacuum suction holes, and the vacuum suction holes are provided with An annular suction groove matching the heat shrink tube is provided. In this example, the Z-axis driving element 43 is a slide cylinder, and the rotation driving element 45 is a rotary cylinder. The working principle is: the vacuum suction seat 46 of the tube removal and transfer sleeve mechanism 4 takes the small section of the heat shrink tube out of the lifting seat 39, and then the vacuum suction seat 46 is driven to move along the X-axis direction or rotate 90 degrees around the Y-axis (there is no order of precedence between the two movements), and moves to the top of the electronic detonator ignition element. Finally, the vacuum suction seat 46 moves down along the Z-axis to put the 5 small sections of the heat shrink tube on the electronic detonator ignition element in the holder 53.

[0027] The hot air blowing mechanism 6 includes a fourth frame, on which a hot air gun cylinder 61 is installed. The hot air gun cylinder 61 drives a hot air gun 62 to move back and forth along the X-axis direction. The air outlet tube of the hot air gun 62 is vertically downward facing the passing card seat 53. Since there are two sets of feeding mechanisms 5, the hot air gun cylinder 61 drives the hot air gun 62 to move back and forth to blow hot air to a group of passing card seats 53, so that the heat shrink tube on the electronic detonator ignition element shrinks after being heated.

[0028] In addition, in order to realize fully automatic operation of the equipment according to the preset program, it is also necessary to connect each actuator (such as a motor, a solenoid valve of a cylinder, a sensor, etc.) to a main controller. There are many options for the main controller. In this embodiment, the main controller preferably uses Mitsubishi's FX-5U type PLC controller. The principle of PLC automatic control is a prior art and will not be elaborated here.
