Description

Technical Field

[0001] The utility model relates to an electronic ignition element ignition test device special for electronic detonators, belonging to the field of civilian blasting equipment. Background Art

[0002] At present, domestic industrial electronic detonators have completely replaced electric detonators and detonating cord detonators. As the key timing control component in electronic detonators, the quality control of electronic ignition elements is very important. Before being assembled with detonators, they must be inspected and tested. Only after passing the test can they be used in the assembly and production of detonators.

[0003] The original electronic ignition element inspection test mode is to first dock the electronic ignition element with the electronic detonator foot line element, then connect the wire clip clip accessories on the foot line element to the detonation busbar, and then connect the detonation busbar to the detonator, and finally set the electronic ignition element delay time and other parameters through the detonator to test the ignition of the electronic ignition element. This mode has the following disadvantages: 1. It is time-consuming to dock the electronic ignition element with the electronic detonator foot line element. If the docking is not firm, it is necessary to use solder to repair it. 2. It is also time-consuming to connect the detonation fuse. After the ignition test, the detonation busbar and the electronic detonator foot line need to be pulled out and separated, which is also time-consuming. 3. A certain amount of electronic detonator foot line elements (line length 3m, including wire clips) need to be consumed, resulting in an increase in production costs, thereby affecting production efficiency. In order to shorten the test time, reduce the operating intensity, further reduce the production cost, and improve production efficiency, it is necessary to invent a test ignition device that is easy to operate and has less consumables, which is exactly the purpose of the present invention.

[0006] The circuit wiring components include a wiring board, a probe, a needle sleeve and a wire; the wiring board is connected to the needle sleeve and the wire respectively, the middle part of the needle sleeve is fixed on the base plate, and the probe is arranged at the upper end of the needle sleeve and partially enters the test hole. The probe is used to contact and conduct with the pin of the electronic ignition element in the test hole during testing.

[0007] Furthermore, the number of test holes correspondingly arranged on the test table, the bottom plate and the circuit wiring components is 80.

[0008] Furthermore, the 80 test holes correspond to 80 sets of probes and needle sleeves respectively, and every two sets of probes and needle sleeves form a group of detection units for correspondingly testing one electronic ignition element.

[0009] Furthermore, the pressure strip fixing component includes a pressure strip and a pressure strip fixing plate.

[0010] Furthermore, the guide component includes a guide column, a guide sleeve and a compression spring. The guide sleeve and the compression spring are arranged in the guide sleeve. The guide column is fixed to the test platform, the guide sleeve is fixed to the base plate, the guide column moves up and down along the guide sleeve, and the compression spring is used to automatically return the test platform after the test is completed.

[0022] The test table 2, the bottom plate 3 and the circuit wiring component 5 are respectively provided with 80 holes arranged regularly. 80 sets of probes 11 and needle sleeves 12 are respectively installed in the corresponding holes, and every two sets of probes 11 and needle sleeves 12 form a group of detection units, which correspondingly test one electronic ignition element 8. The number of electronic ignition elements 8 tested by the device each time ranges from 1 to 40.

[0023] The needle sleeve 12 in the circuit wiring component 5 is soldered on the wiring board 13 and fixed with AB glue through the corresponding hole on the bottom plate 3. After the needle sleeve 12 is fixed, 80 probes 11 are inserted into the needle sleeve 12 in sequence, and the needles of the probes 11 extend into the corresponding test holes of the test table 2 to a depth of 1 to 2 mm. The guide components 4 are symmetrically installed at both ends of the test table 2, and the guide pillars 17 in the guide components 4 are fixed together with the test table 2, and the guide sleeves 19 are fixed together with the bottom plate 3.
