Description

Technical Field

[0001] The invention relates to the technical field of electronic detonator spot welding, in particular to an electronic detonator spot welding machine. Background Art

[0002] Electronic detonators are devices used to detonate explosives, usually in mining, construction, demolition and other fields. They are electronic components composed of circuit boards, capacitors, resistors, coils and leads. Electronic detonators generate magnetic fields by passing current through the coils, causing the wires in the coils to generate electric sparks, igniting explosives or detonating fuses, thereby causing explosions. Electronic detonators have higher accuracy and controllability than traditional gunpowder detonators. They can be precisely timed through electronic equipment to detonate explosives at specific times, thereby achieving more precise blasting effects.

[0003] Therefore, when producing electronic detonators, it is necessary to perform welding operations on the circuit boards. Current production equipment usually adopts double-head simultaneous welding to improve the efficiency of spot welding. Since the spacing between the detonator accommodating cavities on the trays where different detonators are placed is different, it is necessary to adjust the position between the two welding heads when spot welding different detonators. However, the existing method of adjusting the welding heads is usually a means of disassembly and installation of bolts, and the adjustment needs to be performed manually, so it is inconvenient to adjust.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] See also Figure 1-6An electronic detonator spot welding machine comprises a spot welding machine housing 1 and a welding head 12. The top of the spot welding machine housing 1 is connected to a placing frame 2. The end faces of the placing frame 2 are connected to X motion modules 4. The edge of the top surface of the X motion module 4 is connected to a Y motion module 3. The output end of the Y motion module 3 is connected to a Z motion module 5. The movement of the welding head 12 is realized by the X motion module 4, the Y motion module 3 and the Z motion module 5. A through hole is opened at the top of the placing frame 2, and a flip block 11 is connected in the through hole. The output end of the Z motion module 5 is connected to a welding module 7. The welding module 7 includes It includes a welding frame 701, a sliding block 702, a first bevel gear 703, a second bevel gear 704, a screw 705 and a first telescopic rod 706. The middle end of the bottom surface of the welding frame 701 is connected to a motor 6, the bottom surface of the spot welding casing 1 is connected to an air pump 8, the top of the inner wall of the spot welding casing 1 is equidistantly connected to a second telescopic rod 9, the output end of the second telescopic rod 9 is connected to a jet guide plate 10 for cooling and protecting the welding spot, the welding head 12 is connected to the screw 705, and explosion-proof glass is arranged around the spot welding casing 1 except for the feed bin door, so as to form a closed space for processing.

[0033] Furthermore, a placement tray for placing goods is connected to the top of the placement frame 2. During processing, the parts to be welded are placed above the placement tray. The second telescopic rod 9 is fixedly installed on the top of the inner wall of the spot welding housing 1. The maximum extension length of the second telescopic rod 9 should ensure that the top surface height of the jet guide plate 10 is higher than the height of the placement tray, thereby ensuring that the air outlet port of the jet guide plate 10 is level with the top surface of the placement tray. There is an opening at the end of the jet guide plate 10 facing the center part of the spot welding housing 1, and the opening is flush with the surface of the placement tray, so that the gas can be discharged from the air outlet port of the jet guide plate 10 to just cover the surface of the workpiece being welded. After the second telescopic rod 9 is retracted, it should be ensured that the end of the jet guide plate 10 is inside the placement frame 2. The jet guide plate 10 can be recovered after the processing is completed, so that the jet guide plate 10 is protected inside the placement frame 2.

[0034] Furthermore, the output end of the air pump 8 is connected to the jet guide plate 10 by a hard tube. When the jet guide plate 10 moves up and down, the hard tube will slide relatively at the opening of the jet guide plate 10, while ensuring the air tightness between the air pump 8 and the jet guide plate 10. At the same time, after the air pump 8 on one side is started, it will spray inert gas toward the closed area inside the spot welding casing 1, so that the inert gas can quickly cover the surface of the welding point, avoiding oxidation of the welding point, and at the same time allowing the heat at the welding point to be quickly taken away. The air pump 8 on the other side draws air outward, so that the heat and inert gas inside the spot welding casing 1 are quickly discharged, thereby ensuring the temperature inside the spot welding casing 1.

[0035] Furthermore, the flip block 11 is rotatably connected to the area outside the two placement plates on the top surface of the placement frame 2 through a torsion spring. When the jet guide plate 10 moves upward with the second telescopic rod 9, the flip block 11 is pushed upward to open outward.

[0036] Furthermore, the welding frame 701 is fixedly installed at the bottom end of the Z motion module 5. The welding frame 701 is a hollow block with a detachable bottom surface. When internal damage occurs, the welding frame 701 can be disassembled for inspection and repair. There is a downwardly extending partition at the center of the top surface of the inner wall of the welding frame 701, and the partition does not contact the bottom end of the inner wall of the welding frame 701, thereby reserving sufficient rotation space for the second bevel gear 704. The same slideway is provided on both sides of the partition and the welding frame 701, and sliding blocks 702 are slidably connected in the slideways on both sides of the partition. The outward end surface of the sliding block 702 is rotatably connected with a screw rod 705, which passes through the slideway and is rotatably connected to the support block at the output end of the first telescopic rod 706. The first telescopic rod 706 is fixedly installed at the raised top end of the middle end of the bottom edge of the welding frame 701. During the up and down movement of the first telescopic rod 706, it will drive The support block and the screw rod 705 move, and then drive the sliding block 702 to rotate in the slideway. There is damping at the connecting rotating shaft between the support block and the screw rod 705, so that the rotation of the screw rod 705 requires a certain torque from the outside to rotate, thereby avoiding the vibration caused by the movement of the motion module during the spot welding process to offset the position of the screw rod 705 and the welding head 12 connected to its outer end. When the first telescopic rod 706 rises, the first bevel gear 703 will disengage from the meshing point between the second bevel gear 704. When the first telescopic rod 706 descends, the motor 6 rotates at a low speed until the position of the welding head 12 changes, indicating that the first bevel gear 703 and the second bevel gear 704 are meshed, that is, the second bevel gear 704 drives the first bevel gear 703 to rotate, thereby causing the screw rod 705 to rotate, and then adjusting the position of the welding head 12.

[0037] Furthermore, a first bevel gear 703 is fixedly installed on the outer end of the screw rod 705. When the sliding block 702 is at the highest point of the slide, the friction coefficient at the overlap between the first bevel gear 703 and the partition is greater than the friction coefficient between the first bevel gear 703 and the partition when the sliding block 702 is at the lowest point of the slide. The first bevel gear 703 can be further strengthened to avoid torsion caused by vibration generated by the movement of the moving module during spot welding. The second bevel gear 704 is fixedly installed on the output end of the motor 6. There is a gap between the second bevel gear 704 and the welding frame 701. When the sliding block 702 is at the lowest point of the slide, the first bevel gear 703 can mesh with the second bevel gear 704, thereby completing any adjustment of the welding head 12.

[0038] When in use, before spot welding begins, it is necessary to select a placement plate according to the model to be processed, so that the position of the welding head 12 needs to be adjusted. When adjusting, start the motor 6 at a low speed, and slowly lower the first telescopic rod 706 until the position of the welding head 12 changes, indicating that the first bevel gear 703 and the second bevel gear 704 are engaged. At this time, let the motor 6 speed up, and adjust the positions of the two welding heads 12 in this way. After the adjustment is completed, close the warehouse door, move the second telescopic rod 9 upward, push open the flip block 11, pull out the jet guide plate 10 to spray inert gas on the welding point, and discharge the gas in the warehouse, thereby completing the spot welding process of the electronic detonator.
