Description

Technical Field

[0001] The utility model relates to the technical field of detonator production equipment, in particular to an automatic pipe loading mechanism for electronic detonator leg wires. Background Art

[0002] In the civil explosive industry, electronic detonators are commonly used detonators. The core electronic hardware is an electronic module installed in the detonator shell. The electronic module includes components such as a circuit board and a single-chip microcomputer. The electronic module is powered on through the external leg wires of the detonator. During actual production, it is necessary to first assemble the leg wires of the electronic detonator. During assembly, one end of the leg wire needs to be welded and fixed to the terminal on the adapter, then the capacitor is welded to the adapter, and finally the end of the leg wire with the adapter is inserted into the outer tube. Since there are special requirements for the insertion angle of the adapter into the outer tube, it is difficult to correctly insert the adapter into the outer tube when the angle is incorrect. Therefore, at present, the pipe loading of electronic detonator leg wires is usually completed manually. Such a production method has low production efficiency, consumes a large amount of labor, and has high production costs. Content of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the utility model provides an automatic pipe loading mechanism for electronic detonator leg wires, which can improve the production efficiency of electronic detonators and reduce production costs.

[0031] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" 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 a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] 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 peripheral side 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, the adapter 2 can be accurately installed into the outer tube 4 only when the positioning rib 7 is aligned with the positioning groove 6 during assembly.

[0033] As Figures 2-3 shown, an automatic tube loading mechanism for the leg wire of an electronic detonator of the present utility model includes a frame 10. A main conveyor belt 11 for conveying the leg wire is provided on the frame 10. A fixture 12 for clamping the leg wire is provided on the main conveyor belt 11.

The guiding roller is movably disposed in the guiding groove 625. During operation, the outer tube conveyed 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. When the guiding roller moves along the arc-shaped turning section and the vertically extending section of the guiding groove 625, the first outer tube turning seat 622 rotates 90°, so that the outer tube is changed from a horizontal state to a vertical state.

[0035] Specifically, the outer tube positioning mechanism 63 includes an outer tube positioning sleeve 631 and an outer tube positioning servo motor 632 for driving the rotation of the outer tube positioning sleeve 631.

When the outer tube transferring manipulator 65 takes the vertically placed outer tube into the second accommodating groove of the outer tube positioning sleeve 631, the outer tube positioning servo motor 632 drives the rotation of the outer tube positioning sleeve 631, and detects the direction of the outer tube through the cooperation of the optical fiber transmitter and the optical fiber receiver. When the outer tube turns to the correct direction, the rotation stops.

[0036] The second outer tube transfer mechanism 64 includes a second outer tube transfer base 641 and a second outer tube transfer cylinder 642 for driving the movement of the second outer tube transfer base 641.

A first outer tube transfer clamp 655 for moving the outer tube from the first accommodation groove to the second accommodation groove and a second outer tube transfer clamp 656 for moving the outer tube from the second accommodation groove to the third accommodation groove are provided on the fourth outer tube transfer base 653. A first outer tube rotation cylinder 657 for driving the horizontal rotation of the second outer tube is further provided on the fourth outer tube transfer base 653. 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. Next, 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 horizontal outer tube and sleeves it outside the adapter.

The propulsion material-gripping clamp 182 takes out the leg wire with the outer tube pre-installed from the main conveyor belt 11 and sends it to the adapter propulsion mechanism 70. At the same time, the blanking material-gripping clamp 183 takes out the leg wire after propulsion from the adapter propulsion mechanism 70 and sends it to the blanking unit. The outer tube on the leg wire sent to the adapter propulsion mechanism 70 is placed in the outer tube positioning groove at the upper end of the outer tube fixed seat 71.

Then, the propulsion driving cylinder 75 drives the propulsion rod mounting seat 74 to move, and the propulsion rod mounting seat 74 drives the adapter propulsion rod 73 to further push the adapter into the inner part of the outer tube. It should be noted that in the present utility model, the blanking open-clamping mechanism 181, the propulsion material-gripping clamp 182, and the blanking material-gripping clamp 183 are all conventional technologies that are easily conceived by those skilled in the art and will not be elaborated herein.
