They primarily consist of an electronic control module, energy storage capacitors, a bridgewire electric ignition head, and a conventional detonator charge. Their core principle is to receive coded instructions via a built-in microelectronic chip, achieving millisecond or even microsecond precision delay control. Compared to traditional electric detonators, they offer inherent safety and enhanced resistance to stray current interference.

[0003] For example, a device for detecting spot welding defects of electronic detonators disclosed in Chinese patent publication number (CN117428365B) states: "It comprises a rotating disk and two support plates, and the rotating disk is provided with a linear reciprocating drive structure to drive the two support plates to perform linear reciprocating motion; the detection device provided by the present invention not only greatly reduces the labor intensity of the detection personnel, but also can use two multimeters to simultaneously detect two welding points of the electronic control module at one time, thereby improving the detection efficiency; and when performing welding point detection, the multimeter probes will also be polished and cleaned to prevent the accumulated impurities, dust and oxide layer on the surface of the probes from affecting the quality of the detection work."

After completion, the horizontal electric push rod 13 is turned on to drive the L-shaped connecting frame 15 to move closer to the center through the U-shaped connecting frame 14. While the L-shaped connecting frame 15 moves, it drives the sliding frame 16 to slide on the surface of the polished rod 12. At the same time, the sliding frame 16 drives the middle connecting rod 17 to cooperate with the clamping plate 18 to clamp and position the control board. After the clamping plate 18 clamps, the rubber pad 19 is in close contact with the surface of the control board. After completion, the longitudinal electric push rod 37 is turned on to control the contraction of its output end. The contraction of the longitudinal electric push rod 37 drives the top lifting frame 8 to descend inside the sliding sleeve 7, and at the same time drives the test needle 10 at the lower end of the test meter 9 to contact the solder joint on the surface of the control board. At this time, the value of the test meter 9 can be observed to determine whether there is a welding leak problem.

[0033] Example 2

[0034] The electronic detonator spot welding defect detection device provided in Example 1 is further optimized, specifically, as follows Figures 6-10 As shown, both ends of the top plate 6 are fixedly connected with a circulation positioning frame 20, the interior of the circulation positioning frame 20 is fixedly connected with a fixed rod 21, the surface of the fixed rod 21 is rotatably provided with a first gear 22, the surface of the first gear 22 is provided with a chain 23, and the surface of the chain 23 is fixedly connected with a placement plate 38.

[0036] Specifically, the surface of the horizontal support rod 25 is fixedly connected to the first bevel gear 27, the top surface of the bottom supporting plate 1 is rotatably provided with a driven rod 28, the top end of the driven rod 28 is fixedly connected to the second bevel gear 29, the second bevel gear 29 is engaged with the first bevel gear 27, and the surface of the driven rod 28 is rotatably provided with a third gear 30.

[0037] Specifically, a connecting block 31 is fixedly connected to the bottom surface of the U-shaped connecting frame 14 , and a rack 32 is fixedly connected to one end of the connecting block 31 away from the U-shaped connecting frame 14 . The rack 32 is meshed with the third gear 30 .

[0038] Specifically, a ratchet 33 is fixedly connected to the surface of the driven rod 28, a positioning shaft 34 is fixedly connected to the top surface of the third gear 30, a ratchet 35 is rotatably provided on the top end of the positioning shaft 34, the ratchet 35 is engaged with the ratchet 33, and a torsion spring 36 is sleeved on the surface of the positioning shaft 34, and the two ends of the torsion spring 36 are fixedly connected to the third gear 30 and the ratchet 35 respectively.

[0039] Specifically, the test structure 4 includes a sliding sleeve 7 fixedly connected to the top surface of the top plate 6, a top lifting frame 8 is slidingly provided inside the sliding sleeve 7, a test table 9 is fixedly connected to the top of the top lifting frame 8, and a test needle 10 is longitudinally provided at the test end of the test table 9.

[0040] Through the above structural design, the control panel is placed in the middle of the placement plate 38 during inspection. After completion, the horizontal electric push rod 13 is turned on to drive the L-shaped connecting frame 15 to move closer to the center through the U-shaped connecting frame 14. While the L-shaped connecting frame 15 moves, it drives the sliding frame 16 to slide on the surface of the polished rod 12. At the same time, the sliding frame 16 drives the middle connecting rod 17 to cooperate with the clamping plate 18 to clamp and position the control panel. After the clamping plate 18 is clamped, the rubber pad 19 is in close contact with the surface of the control panel. When the U-shaped connecting frame 14 moves, the rack 32 can be driven to move through the connecting block 31 at the lower end, thereby causing the third gear 30 to cooperate with the ratchet 33 and the ratchet 35 to drive the driven rod 28 to rotate. When the driven rod 28 rotates, the second gear 26 and the cross support rod 25 can be driven to rotate through the first bevel gear 27. When the cross support rod 25 rotates, the chain 23 is driven to rotate. The rotation of the chain 23 drives the placement plate 38 to move to the middle of the clamping plate 18. By bringing the clamping plates 18 closer to each other, the control panel can be quickly switched and clamped. After completion, the longitudinal electric push rod 37 is turned on to control the contraction of its output end. The contraction of the longitudinal electric push rod 37 drives the top lifting frame 8 to descend inside the sliding sleeve 7, and at the same time drives the test needle 10 at the lower end of the test meter 9 to contact the solder joint on the surface of the control board. At this time, the value of the test meter 9 can be observed to determine whether there is a welding leak problem; After the detection is completed, the output end of the horizontal electric push rod 13 extends, driving the rack 32 to move through the U-shaped connecting frame 14 and the connecting block 31. While the rack 32 moves, it drives the third gear 30 to rotate on the surface of the driven rod 28. At this time, the ratchet 33 and the ratchet teeth 35 stop engaging and are tightly attached to the surface of the ratchet 33 through the action of the torsion spring 36. At this time, the third gear 30 can only rotate on its own and cannot drive the driven rod 28 to rotate, so that the one-way circulation conveying and monitoring of the control board can be achieved.
