[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 bottom plate and a plurality of core mold assemblies 200 arranged on the core mold bottom plate. In the manufacturing process of the detonator, there is a step of putting a detonator bottom cover 300 on the core shaft 2001 of the core mold assembly 200. The bottom cover 300 is provided with a plurality of holes 3001. Since the holes 3001 need to allow the core shaft of the core mold assembly 200 to pass through, the holes on the bottom cover need to correspond to the corresponding core shafts during the installation of the bottom cover to the detonator core mold. Otherwise, the bottom cover and the detonator core mold cannot be assembled. In addition, due to the presence of other structures such as the boss 3002 on the bottom cover 300, the relative positions of the holes on the bottom cover in the horizontal plane are fixed. The prior art generally detects the hole position of the bottom cover by visual inspection, then rotates the bottom cover to adjust the bottom cover, and then assembles the bottom cover to the core shaft of the core mold assembly. The whole process is time-consuming, and the corresponding mechanism structure is relatively complicated, resulting in a high manufacturing cost of the detonator bottom cover assembly machine.

[0043] The working process of the detonator bottom cover assembly machine is briefly described as follows:

[0044] The bottom cover loading robot places the grabbed bottom cover on the bottom cover carrier. After the carrier conveyor line moves the bottom cover carrier to the adjustment position, the adjustment lifting drive drives the adjustment lifting frame to rise. The rotating head passes through the window to lift the bottom cover in the bottom cover placement slot, so that the upper part of the bottom cover contacts the bottom surface of the supporting block. At the same time, the top surface of the latch member contacts the bottom surface of the bottom cover. When the hole on the bottom 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 drives the rotating head to rotate one circle. During the rotation of the rotating head, the hole on the bottom cover is aligned with the corresponding latch member, the elastic member recovers its deformation, the latch member is inserted into the corresponding hole of the bottom cover, and the rotating head is rotated. Continuing rotation of the head will drive the bottom cover to rotate, so that the bottom cover is rotated to the initial position, and then according to the detection result of the light detection sensor, the rotary drive member selects whether to continue to drive the rotary head to rotate, thereby completing the adjustment of the bottom cover; taking the bottom cover with two holes as an example, when the bottom cover is rotated to the initial position, when the detection path of the light detection sensor is not blocked by the boss on the bottom cover, the rotary drive member continues to drive the rotary head to rotate 180°, so that the bottom cover is rotated to the preset position, when the detection path of the light detection sensor is blocked by the boss on the bottom cover, the rotary drive member remains stopped, and at this time, the initial position of the bottom cover is the preset position.

[0045] When all the bottom covers on the bottom cover carrier are adjusted, the carrier conveyor line moves the bottom cover carrier to the unloading position to wait for the bottom cover unloading robot to unload the bottom cover;

[0046] When the detonator core mold with the bottom cover sleeved on the core shaft flows to the working position of the bottom cover crimping mechanism, the bottom cover crimping mechanism performs secondary crimping on the bottom cover sleeved on the core shaft of the detonator core mold.

[0047] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention.
