In traditional manual welding, the welding position of the lead wire and the electronic control module depends on the operator's experience, which can easily lead to misalignment or displacement.

[0003] For example, Chinese utility model patent (CN211759071U) discloses a welding fixture for hook welding of electronic detonator lead wires, including a base plate, a control module cover plate for fixing and pressing the electronic control module, and a lead wire pressing mechanism for pressing the lead wires with plugs; the base plate has multiple grooves with plugs arranged side by side for positioning the lead wires of the electronic detonator, and the base plate at the upper end of the grooves with plugs has two through slots that extend laterally and pass through each other, and welding pads and pads are respectively installed in the two through slots.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1

[0033] Reference Figures 1-6 A welding fixture for hooking electronic detonator leads includes a base plate 1. The base plate 1 has multiple grooves arranged side by side for positioning the lead wires of the electronic detonator. The base plate 1 also has multiple positioning grooves for positioning and fixing electronic control modules. The positioning grooves of the electronic control modules correspond one-to-one with the lead wire grooves. A first pressure plate 2 is rotatably connected to one end of the top side of the base plate 1. A fixing rod 3 is rotatably connected to the end of the top side of the base plate 1 away from the first pressure plate 2. A second pressure plate 4 is rotatably connected to the outer side of one side of the base plate 1. A lifting mechanism is provided on the base plate 1 for lifting the detonator after welding.

[0034] The lifting mechanism includes a first rotating rod 5, a first bevel gear 6, a second bevel gear 7, a second transmission rod 8, and a third bevel gear 9. The first rotating rod 5 is rotatably connected to the inner side of the base plate 1, and the first bevel gear 6 is fixed to the outer side of the first rotating rod 5. The first bevel gear 6 is located in the middle of the first rotating rod 5 and is located on the inner side of the base plate 1. The second bevel gear 7 is rotatably connected to one side of the first bevel gear 6, and the second transmission rod 8 is fixed to one side of the second bevel gear 7. The second transmission rod 8 is rotatably connected to the base plate 1, and the third bevel gear 9 is fixed through the base plate 1 at both ends of the first rotating rod 5.

[0035] The lifting mechanism also includes a fourth bevel gear 10, a lead screw 11, a connecting plate 12, and a pad 13. The top of the third bevel gear 9 is meshed with the fourth bevel gear 10. The top of the fourth bevel gear 10 is fixed with the lead screw 11. The lead screw 11 is rotatably connected to the base plate 1. The outer side of the lead screw 11 is threaded with the connecting plate 12. Pads 13 are fixed on both sides of the connecting plate 12. The pads 13 are slidably connected to the base plate 1. A limiting component is provided on the outer side of the second transmission rod 8.

[0036] After welding is completed, the lifting mechanism controls the pad 13 to lift, and the pad 13 drives the electronic control module and lead wires to lift as a whole, so that the electronic control module and lead wires are separated from the positioning groove, reducing the tedious manual removal.

[0037] Guide grooves 14 are provided on the inner sides of both ends of the base plate 1. Guide plates 15 are slidably connected to the inner sides of the guide grooves 14. The guide plates 15 are fixedly connected to the corresponding connecting plates 12.

[0038] Example 2

[0039] Reference Figure 5 and Figure 7 A welding fixture for hooking electronic detonator leads, the limiting components include a limiting gear 16, a limiting rack 17, a fixing plate 18, a guide rod 19, a spring 20, a rotating rod 21, and a cam 22. The limiting gear 16 is fixed on one side of the outer side of the second transmission rod 8, and the limiting rack 17 is snapped onto the top of the limiting gear 16. Two fixing plates 18 are fixed on one side of the base plate 1, and the guide rod 19 is fixed on the inner side of the fixing plate 18. The guide rod 19 is slidably connected to the limiting rack 17. The spring 20 is sleeved on the outer side of the bottom of the guide rod 19, and the top of the spring 20 is fixedly connected to the limiting rack 17. The rotating rod 21 is rotatably connected to the side of the base plate 1 close to the limiting rack 17 and located on the top of the limiting rack 17. The cam 22 is fixed on the outer side of the rotating rod 21, and the bottom of the cam 22 contacts the top of the limiting rack 17.

[0040] The lifting mechanism can be locked by the design of the limiting components, preventing it from being touched arbitrarily.

[0041] The guide plate 15 is I-shaped. The I-shaped design allows the guide plate 15 to be snapped into the inner side of the base plate 1. At the same time, the guide plate 15 can guide the movement of the connecting plate 12.

[0042] The process of using the electronic detonator lead hook welding fixture provided by this utility model is as follows: multiple electronic control modules are installed one by one into the electronic control module positioning groove. After installation, the second pressure plate 4 is rotated downward around the two bolts and pressed onto the electronic control module to complete the positioning and fixing of the electronic control module. Then, the outer plastic layer of the lead wire to be welded is removed from the plugged lead wire end, the lead wire end to be welded is cut flat, the head of the lead wire end to be welded is bent, and multiple plugged lead wires are installed one by one into the plugged lead wire groove. The bent head of the lead wire to be welded is inserted into the hole of the corresponding electronic control module. The lead wire is fixed on the welding fixture, and welding can be completed on the automatic soldering machine.

[0043] After welding, in order to make it easier to remove the welded module, rotate the first pressure plate 2 and the second pressure plate 4. At this time, the first pressure plate 2 and the second pressure plate 4 will no longer press the electronic detonator with plug wire and electronic control module.

[0044] Then rotate the rotating rod 21, so that the cam 22, which is fixedly connected to the rotating rod 21, also rotates. At this time, the cam 22 no longer presses the limiting rack 17. At this time, under the action of the spring force of the spring 20, the limiting rack 17 moves to the top along the guide rod 19. At this time, the limiting rack 17 no longer engages with the limiting gear 16. At this time, the second transmission rod 8, which is fixedly connected to the limiting gear 16, can rotate freely.

[0045] Then, the second transmission rod 8 is rotated, causing the second bevel gear 7, which is fixedly connected to the second transmission rod 8, to also rotate. Since the second bevel gear 7 is meshed with the first bevel gear 6 and the first bevel gear 6 is fixedly connected to the first rotating rod 5, the rotation of the second transmission rod 8 drives the first rotating rod 5 to rotate, causing the two third bevel gears 9, which are fixedly connected to the first rotating rod 5, to also rotate. Since the third bevel gear 9 is meshed with the fourth bevel gear 10, the lead screw 11, which is fixedly connected to the fourth bevel gear 10, also rotates. Since the connecting plate 12 is threadedly connected to the lead screw 11, the synchronous rotation of the two lead screws 11 drives the connecting plate 12 to move, thereby causing the two pads 13, which are fixed to the connecting plate 12, to move synchronously.

[0046] As the two pads 13 move synchronously to the top, they remove the welded detonator from the placement slot, making it easier to retrieve the welded parts.

[0047] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to specific implementations.
