[0038] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it should not be construed as a limitation to the present invention.

[0039] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0040] First, please refer to Figure 1 As shown, when assembling the leg wire 1 of the electronic detonator, it is necessary to first connect it to the adapter 2, then weld the capacitor 3 to the adapter 2, and finally install the adapter 2 into the outer tube 4. Since the positioning groove 6 is provided on the periphery of the end plate 5 of the adapter 2, and the positioning rib 7 corresponding to the positioning groove 6 is provided on the inner side of the outer tube 4, it is necessary to align the positioning rib 7 with the positioning groove 6 during assembly to accurately install the adapter 2 into the outer tube 4.

A defective product discharging manipulator 17 is provided on the side of the vision inspection mechanism 16 away from the capacitor welding mechanism 41. Since the lead wires have a certain length, in order to make the conveying of the lead wires more stable, a secondary conveyor belt 13 parallel to the main conveyor belt 11 is further provided on the frame 10 in front of the main conveyor belt 11. In this way, when conveying the lead wires, one end of the lead wire is clamped and fixed on the fixture 12 of the main conveyor belt 11, and the other end is supported on the secondary conveyor belt 13, thereby avoiding the situation that the lead wires are wound or caught on the frame 10 during the conveying process due to their excessive length, resulting in pulling.

A first connecting arm is provided on the first rotating seat 35. The adapter feeding clamp 36 is fixedly provided at the end of the first connecting arm. During operation, after the adapter feeding clamp 36 clamps the adapter, it rotates horizontally by 90° under the drive of the adapter feeding steering cylinder 33, so that the end of the adapter provided with terminals faces the lead wire. Then, under the drive of the adapter feeding driving mechanism 34, it is riveted to the lead wire at the adapter riveting mechanism 30, and then is moved to the adapter welding mechanism 31 for welding and fixing under the conveyance of the main conveyor belt 11. In the present utility model, the adapter riveting mechanism 30 and the adapter welding mechanism 31 are both conventional technical solutions that are easily conceivable by those skilled in the art, and will not be elaborated here.

Then, the second capacitor transfer manipulator 45 sends the capacitor with expanded pins to one side of the capacitor riveting mechanism 40. Then, the third capacitor transfer manipulator 46 clamps the capacitor to the capacitor riveting mechanism 40. The upper capacitor riveting cylinder 402 and the lower capacitor riveting cylinder 403 respectively control the activities of the capacitor upper riveting knife and the capacitor lower riveting knife 406, so as to rivet the pins of the capacitor to the terminals on the adapter. Finally, it is conveyed to the capacitor welding mechanism 41 by the main conveyor belt 11 for welding and fixing. By setting the first capacitor transfer manipulator 44, the turning of the capacitor feeding can be realized, so that the pins of the capacitor can extend towards the terminals on the adapter. By setting the pin expanding assembly 43, the pin spacing on the capacitor can be enlarged to adapt to the spacing of the terminals on the adapter.

During operation, the outer tube transported by the outer tube feeding track 61 enters the first accommodating groove in a horizontal state. Then, the first outer tube transferring cylinder 623 drives the activity of the first outer tube transferring seat 621. The guiding roller first moves along the horizontal transferring section of the guiding groove 625, so that the outer tube first horizontally moves out of the outer tube feeding track 61.

By providing the outer tube positioning mechanism 63, the positioning of the outer tube direction is achieved. By providing the first outer tube rotation cylinder 657, the direction of the outer tube is adjusted according to the assembly direction, so that the positioning rib 7 on the outer tube is aligned with the positioning groove 6 on the adapter 2 during the assembly of the outer tube.

The outer tube preloading and picking clamp 531 is mounted on the outer tube preloading and picking seat 532. The outer tube preloading and picking cylinder 533 is mounted on the outer tube preloading sliding seat. During operation, the leg wire is conveyed by the main conveyor belt 11 to the outer tube preloading mechanism 50. First, the adapter is clamped and positioned by the positioning clamp 515. Then, the upper clamping plate 511 and the lower clamping plate 512 are respectively clamped on the upper and lower sides of the adapter end plate. Then, the positioning clamp 515 is opened and moved down. Then, the outer tube turning and picking clamp 521 of the outer tube turning mechanism 52 clamps the outer tube from the second outer tube material transfer mechanism 64 and turns the outer tube from a vertical state to a horizontal state. The outer tube preloading manipulator 53 clamps the outer tube in the horizontal state and sleevs it outside the adapter. To prevent the outer tube from falling, an outer tube support plate 19 is provided between the outer tube preloading mechanism 50 and the adapter pushing mechanism 70.

In the present utility model, the pushing and transferring manipulator 18 is provided with a blanking open-clamp mechanism, a pushing and picking clamp, and a blanking and picking clamp. During operation, the blanking open-clamp mechanism of the pushing and transferring manipulator 18 opens the clamp 12 on the main conveyor belt 11. The pushing and picking clamp takes out the leg wire with the outer tube pre-installed from the main conveyor belt 11 and sends it to the adapter pushing mechanism 70. At the same time, the blanking and picking clamp takes out the leg wire after pushing from the adapter pushing mechanism 70 and sends it to the blanking unit. The outer tube on the leg wire sent to the adapter pushing mechanism 70 is placed in the outer tube positioning groove at the upper end of the outer tube fixing base 71. The clamp block driving cylinder 76 controls the outer tube fixing clamp block 72 to fix the outer tube in the outer tube fixing groove. Then, the pushing driving cylinder 75 drives the pushing rod mounting seat 74 to move, and the adapter pushing rod 73 is driven by the pushing rod mounting seat 74 to further push the adapter into the inner part of the outer tube.
