[0002] The detonator is also called the booster column. It is used to detonate low-sensitivity explosives such as ammonium nitrate oil explosives, slurry explosives, emulsion explosives and other explosives without detonator sensitivity. The detonation principle of the detonator is to detonate the detonator through the detonator or detonating cord inserted in the detonator, and then the detonator detonates the low-sensitivity explosives. The detonator plays the role of amplifying the detonation wave.

[0003] In the process of producing detonators, detonator core molds are used. Figure 1 A detonator core mold is shown. The detonator core mold 100 includes a core mold base plate and a plurality of core mold assemblies 200 arranged on the core mold base plate. In the manufacturing process of the detonator, there is a step of installing an upper cover 400 on the top of a cylindrical body 300 sleeved on the core mold base of the core mold assembly 200. The upper cover 400 is provided with a plurality of holes 4001 for the core shaft of the core mold assembly 200 to pass through. Different holes 4001 have different sizes. Therefore, in the process of installing the upper cover to the cylindrical body, the holes on the upper cover need to correspond to the corresponding core shafts, otherwise the upper cover and the cylindrical body cannot be assembled. The prior art generally detects the hole position of the upper cover by visual detection, then rotates the upper cover to adjust the upper cover, and then assembles the upper cover to the cylindrical body. The whole process is time-consuming, and the corresponding mechanism structure is relatively complicated, resulting in a high manufacturing cost of the detonator upper cover assembly machine.

[0054] The working process of the detonator cover assembly machine is briefly described as follows:

[0055] The upper cover loading manipulator places the grabbed upper cover on the upper cover carrier. After the carrier conveyor line moves the upper cover carrier to the adjustment position, the adjustment lifting drive member drives the adjustment lifting frame to descend, so that the bottom surface of the latch member contacts the top surface of the upper cover. When the hole on the upper cover is misaligned with the corresponding latch member, the latch member retracts into the rotating head, the elastic member is compressed, and the rotating drive member drives the rotating head to rotate one circle. During the rotation of the rotating head, the hole on the upper cover is aligned with the corresponding latch member, the elastic member recovers its deformation, and the latch member is inserted into the corresponding hole of the upper cover. The rotating head continues to rotate to drive the upper cover to rotate, so that the upper cover is rotated to the preset position, and the adjustment work of the upper cover is completed;

[0056] When all the upper covers on the upper cover carrier are adjusted, the carrier conveyor line moves the upper cover carrier to the unloading position to wait for the upper cover unloading robot to unload the materials;

[0057] The lifting drive in the first lifting and positioning mechanism drives the core mold of the detonator on the core mold conveying line to rise, the positioning lifting drive drives the positioning clamping plate to descend, and the clamping drive drives the positioning clamping plate to clamp the cylindrical body on the core mold of the detonator. Then, the upper cover unloading manipulator inserts the bottom end of the upper cover it clamps into the top of the cylindrical body; then, the upper cover unloading manipulator is reset, and the positioning lifting drive drives the positioning clamping plate to rise so that the core mold of the detonator conveyed on the core mold conveying line can pass from under the positioning clamping plate, and the first lifting and positioning mechanism is reset, and the core mold of the detonator flows to the lower station of the core mold conveying line;

[0058] The second lifting and positioning mechanism works, and its working process is the same as that of the first lifting and positioning mechanism. After the positioning clamp in the second lifting and positioning mechanism clamps the cylindrical body on the core mold of the detonator, the upper cover crimping mechanism performs secondary crimping on the upper cover on the cylindrical body, and the second lifting and positioning mechanism is reset, and the core mold of the detonator flows to the lower station of the core mold conveying line;

[0059] The light detection mechanism performs top surface inspection on the assembled upper cover to distinguish good from defective products. The core molds of the detonators carrying defective products are transferred to the collection table, and the core molds of the detonators carrying all the semi-finished products of good products continue to flow to the next workstation along the core mold conveyor line.

[0060] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
