Description

Technical Field

[0001] This invention relates to the field of electronic detonator spot welding technology, specifically to an electronic detonator spot welding machine. Background Technology

[0002] An electronic detonator is a device used to detonate explosives, commonly used in mining, construction, and demolition. It is an electronic component consisting of a circuit board, capacitor, resistor, coil, and leads. An electronic detonator generates a magnetic field by passing current through a coil, causing an electric spark in the coil's wires. This spark ignites the explosive or detonates the fuse, thus triggering an explosion. Compared to traditional gunpowder detonators, electronic detonators offer greater precision and controllability. They can be precisely timed using electronic equipment, allowing the explosive to detonate at a specific point in time, achieving a more accurate blasting effect.

[0003] Therefore, when producing electronic detonators, it is necessary to solder their circuit boards. At present, the production equipment usually adopts dual-head simultaneous soldering to improve the efficiency of spot welding. Since the spacing of the detonator receiving cavities on the placement tray of different detonators is different, the position between the two welding heads needs to be adjusted when spot welding different detonators. However, the existing method of adjusting the welding heads is usually the means of bolt disassembly and installation, which requires manual adjustment, so it is inconvenient. Summary of the Invention

[0004] Purpose of the invention

[0005] To address the shortcomings of existing technologies, this invention provides an electronic detonator spot welding machine, which has advantages such as easy adjustment of the welding head, thus solving the aforementioned technical problems.

[0006] Technical solution

[0008] As a preferred embodiment of the present invention, the top of the placement frame is connected to a placement tray for placing goods, and the second telescopic rod is fixedly installed on the upper part of the bottom of the inner side of the spot welding machine housing. The maximum extension length of the second telescopic rod should ensure that the top surface of the jet guide plate is higher than the height of the placement tray, and the second telescopic rod should ensure that the end of the jet guide plate is inside the placement frame after it is retracted.

[0009] As a preferred embodiment of the present invention, the flipping block is rotatably connected to the area outside the two placement disks on the top surface of the placement frame by a torsion spring, and the opening and closing direction of the flipping block is outward.

[0010] As a preferred embodiment of the present invention, the air pump output end is connected to the jet guide plate by a rigid tube, and the rigid tube can slide on the inner wall of the jet guide plate without causing gas leakage. The end of the jet guide plate has an opening facing the center of the spot welding machine housing, and the opening is flush with the surface of the placement tray.

[0011] As a preferred embodiment of the present invention, the two air pumps have opposite air inlet and outlet directions.

[0012] As a preferred embodiment of the present invention, the welding module includes a welding frame, a sliding block, a first bevel gear, a second bevel gear, a lead screw, and a first telescopic rod.

[0013] As a preferred technical solution of the present invention, the welding frame is fixedly installed at the bottom end of the Z motion module. The welding frame is a hollow block with a detachable bottom surface. A motor is fixedly installed at the middle of the bottom surface of the welding frame. There is a downwardly extending partition at the center of the top surface of the inner wall of the welding frame. The partition does not contact the bottom end of the inner wall of the welding frame. The same slide rails are provided on both sides of the partition and both sides of the welding frame. Sliding blocks are slidably connected in the slide rails on both sides of the partition.

[0014] As a preferred embodiment of the present invention, the outer end face of the sliding block is rotatably connected to a lead screw, the lead screw passes through the slide rail and is connected to the output end of the first telescopic rod, and a first bevel gear is fixedly installed on the outer end of the lead screw. When the sliding block is at the highest point of the slide rail, the friction coefficient at the point where the first bevel gear coincides with the partition is greater than the friction coefficient between the first bevel gear and the partition when the sliding block is at the lowest point of the slide rail.

[0015] As a preferred embodiment of the present invention, the second bevel gear is fixedly installed at the motor output end, and there is a gap between the second bevel gear and the welding frame. When the sliding block is at the lowest point of the slide, the first bevel gear can mesh with the second bevel gear, and the welding head is threadedly connected to the outer end of the lead screw.

The support block is rotatably connected to the lead screw, and there is damping at the rotating shaft connecting the support block and the lead screw.

[0017] Compared with the prior art, the present invention provides an electronic detonator spot welding machine, which has the following beneficial effects:

[0018] 1. This invention requires the selection of a placement plate according to the processing model before spot welding begins, which necessitates adjusting the position of the welding head. During adjustment, the motor is started at low speed, and the first telescopic rod is slowly lowered until the position of the welding head changes, indicating that the first bevel gear and the second bevel gear are meshing. At this point, the motor is accelerated, and the position of the two welding heads is adjusted repeatedly.

[0019] 2. After the air pump is started, the present invention sprays inert gas into the closed area inside the spot welding machine housing, allowing the inert gas to quickly cover the surface of the welding point, preventing oxidation of the welding point, and at the same time allowing the heat at the welding point to be quickly carried away. The air pump on the other side draws air outward, allowing the heat and inert gas inside the spot welding machine housing to be quickly discharged, ensuring the temperature inside the spot welding machine housing.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Please see Figure 1-6An electronic detonator spot welding machine includes a spot welding machine housing 1 and a welding head 12. A placement frame 2 is connected to the top of the spot welding machine housing 1. X-motion modules 4 are connected to both end faces of the placement frame 2. A Y-motion module 3 is connected to the top edge of the X-motion module 4. A Z-motion module 5 is connected to the output end of the Y-motion module 3. The movement of the welding head 12 is achieved through the X-motion module 4, Y-motion module 3, and Z-motion module 5. A through hole is opened at the top of the placement frame 2, and a flipping block 11 is connected inside the through hole. A welding module 7 is connected to the output end of the Z-motion module 5. The welding module 7 includes... The welding frame 701, sliding block 702, first bevel gear 703, second bevel gear 704, lead screw 705, and first telescopic rod 706 are included. A motor 6 is connected to the middle of the bottom surface of the welding frame 701. An air pump 8 is connected to the bottom surface of the spot welding machine housing 1. A second telescopic rod 9 is equidistantly connected to the upper end of the bottom inner side of the spot welding machine housing 1. An air jet guide plate 10 for cooling and protecting the weld point is connected to the output end of the second telescopic rod 9. The welding head 12 is connected to the lead screw 705. Explosion-proof glass is installed around the spot welding machine housing 1, except for the feed hopper door, to form a sealed processing space.

[0033] Furthermore, the top of the placement frame 2 is connected to a placement tray for placing goods. During processing, the workpiece to be welded is placed on the placement tray. The second telescopic rod 9 is fixedly installed on the upper bottom of the inner side of the spot welding machine housing 1. The maximum extension length of the second telescopic rod 9 should ensure that the top surface of the jet guide plate 10 is higher than the height of the placement tray, thereby ensuring that the air outlet of the jet guide plate 10 is horizontal with the top surface of the placement tray. The end of the jet guide plate 10 has an opening facing the center of the spot welding machine 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 of the jet guide plate 10 and can just cover the surface of the workpiece being welded. After the second telescopic rod 9 is retracted, it should ensure that the end of the jet guide plate 10 is inside the placement frame 2. The jet guide plate 10 can be retracted after processing, 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 via a rigid tube. When the jet guide plate 10 moves up and down, the rigid tube will slide relative to the opening of the jet guide plate 10, ensuring the airtightness between the air pump 8 and the jet guide plate 10. At the same time, after one side of the air pump 8 is started, it will spray inert gas into the closed area inside the spot welding machine housing 1, allowing the inert gas to quickly cover the surface of the welding point, preventing oxidation of the welding point, and allowing the heat at the welding point to be quickly carried away. The other side of the air pump 8 will draw air outward, allowing the heat and inert gas inside the spot welding machine housing 1 to be quickly discharged, ensuring the temperature inside the spot welding machine housing 1.

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

[0036] Furthermore, the welding frame 701 is fixedly installed at the bottom of the Z-motion module 5. The welding frame 701 is a hollow block with a detachable bottom surface, which can be disassembled and repaired in case of internal damage. There is a downward-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 of the inner wall of the welding frame 701, thus providing sufficient rotation space for the second bevel gear 704. The same slide rails are provided on both sides of the partition and both sides of the welding frame 701, and sliding blocks 702 are slidably connected in the slide rails on both sides of the partition. The outward end face of the sliding block 702 is rotatably connected to the lead screw 705. The lead screw 705 passes through the slide rail 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 protruding top at the middle 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 lead screw 705 move, which in turn causes the sliding block 702 to rotate within the slide. There is damping at the rotating shaft connecting the support block and the lead screw 705, so that the rotation of the lead screw 705 requires a certain torque from the outside to rotate. This avoids the displacement of the lead screw 705 and the welding head 12 connected to its outer end caused by the vibration generated by the movement of the motion module during spot welding. When the first telescopic rod 706 rises, the meshing between the first bevel gear 703 and the second bevel gear 704 will disengage. When the first telescopic rod 706 falls, the motor 6 rotates at low speed until the position of the welding head 12 changes, indicating that the first bevel gear 703 and the second bevel gear 704 have meshed. That is, the second bevel gear 704 drives the first bevel gear 703 to rotate, thereby causing the lead screw 705 to rotate, and thus adjusting the position of the welding head 12.

[0037] Furthermore, a first bevel gear 703 is fixedly installed on the outer end of the lead screw 705. When the sliding block 702 is at the highest point of the slide, the friction coefficient between the first bevel gear 703 and the partition plate is greater than that between the first bevel gear 703 and the partition plate when the sliding block 702 is at the lowest point of the slide. This can further strengthen the first bevel gear 703 and prevent the torsion caused by the vibration of the moving module during the spot welding process. 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 the arbitrary adjustment of the welding head 12.

[0038] During use, before spot welding begins, the placement tray needs to be selected according to the model being processed, which requires adjusting the position of the welding head 12. During adjustment, the motor 6 is started at low speed, and the first telescopic rod 706 is slowly lowered until the position of the welding head 12 changes, indicating that the first bevel gear 703 and the second bevel gear 704 are meshing. At this point, the motor 6 is accelerated, and the positions of the two welding heads 12 are adjusted repeatedly. After the adjustment is completed, the chamber door is closed, the second telescopic rod 9 is moved upward, the flipping block 11 is pushed open, and the jet guide plate 10 is pulled out to spray inert gas at the welding point and to discharge the gas inside the chamber, thereby completing the spot welding process of the electronic detonator.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
