Detailed Implementation

[0035] Example 1: As Figures 1 to 7 As shown, an automatic electrode welding device includes a welding device frame 1. The front and left and right sides of the welding device frame 1 are equipped with glass windows, which not only facilitate manual observation of the operation of the automatic welding device, but also prevent welding slag and sparks from flying and injuring personnel during the welding process. Of course, due to the influence of the left and right conveying equipment bodies 30, a certain space needs to be reserved below the left and right sides of the welding device frame 1 to ensure the normal transport of the battery. Two guide shafts 2 are sleeved inside the welding device frame 1. A cross plate 3 is fixedly connected to the top of the guide shaft 2. A locking ring 4 is fixedly connected to the outside of the guide shaft 2. A positioning frame 5 is fixedly connected to the outside of the locking ring 4.

[0036] An optical axis 6 is fixedly connected inside the positioning frame 5, and an adjusting screw 7 is also fixedly connected inside the positioning frame 5. A wedge-shaped positioning frame 8 is set outside the adjusting screw 7. The position of the wedge-shaped positioning frame 8 can be manually adjusted according to the different spacing of the battery terminals. At this time, the wedge-shaped positioning frame 8 will move and adjust outside the adjusting screw 7 and outside the optical axis 6, and be fixed by nuts after adjustment. A mounting plate 9 is fixedly connected to the top of the wedge-shaped positioning frame 8. The ignition device 10 is installed and fixed to one side of the mounting plate 9 by bolts. The ignition device 10 is fixedly connected to one side of the mounting plate 9. The ignition device 10 generates an electric spark by instantaneous high voltage discharge to ignite the gas sprayed by the flame gun 26. The technology of the ignition device 10 is very mature. It is connected to an external power source through wires. Those skilled in the art can and should understand its specific functions and structure, so it will not be described in detail here.

[0037] The wedge-shaped positioning frame 8 has a bowl-shaped mold 11 fixedly connected inside. When the flame gun 26 is working, it will only move inside the bowl-shaped mold 11 to perform welding work on the pole. The bottom of the bowl-shaped mold 11 is provided with a positioning insert 12 with rounded corners. Because the positioning insert 12 has rounded corners inside, the pole will be shaped by the positioning insert 12 during welding. Therefore, the rounded corners will be automatically generated after the pole is welded, and no further processing of the rounded corners is required. The top of the wedge-shaped positioning frame 8 is fixedly connected with a limiting square shell 13. The limiting square shell 13 is set above the bowl-shaped mold 11. The limiting square shell 13 shields and protects the area where the flame gun 26 is welding, preventing the strong light and welding slag from spreading and affecting the surrounding environment.

[0038] A hydraulic cylinder 14 is fixedly connected to the top of the welding device frame 1. The output end of the hydraulic cylinder 14 is fixedly connected to the middle of the cross plate 3. The output end of the hydraulic cylinder 14 pushes the cross plate 3 to descend, causing the cross plate 3 to drive the guide shaft 2, wedge positioning frame 8, and support platform 15 to descend as a whole. This allows the bowl-shaped mold 11 and positioning insert 12 to position and fix the battery terminals. Then, the flame gun 26 is used to weld the terminals. During the welding process, the output end of the second electric push rod 29 pushes the lifting rod 28 to drive the support platform 15 and other components, as well as the flame gun 26, to descend. This allows the flame gun 26 to approach the bowl-shaped mold 11 and continue welding the terminals. After the terminals are welded, the flame gun 26 is raised away from the bowl-shaped mold 11. Then, the guide shaft 2, wedge positioning frame 8, and support platform 15 are raised as a whole, and the battery can then be transported out of the welding device frame 1.

[0039] The guide shaft 2 is externally slidably connected to a support 15. The bottom of the support 15 is fixedly connected to two sleeves 16. When the support 15 is raised or lowered, the two sleeves 16 will also be raised or lowered outside the guide shaft 2, which can improve the stability of the support 15 during the raising or lowering. The inside of the sleeves 16 is slidably connected to the inside of the guide shaft 2. The top of the support 15 is fixedly connected to a top cover 17.

[0040] A positioning rod 18 is fixedly connected inside the top cover 17. The positioning rod 18 connects to the reciprocating table 20, providing limiting support and improving the stability of the reciprocating table 20 during operation. A lead screw 19 is rotatably connected inside the top cover 17, and the reciprocating table 20 is threadedly connected to the outside of the lead screw 19. The inside of the reciprocating table 20 is slidably connected to the outside of the positioning rod 18. A first electric push rod 21 is fixedly connected to the top of the reciprocating table 20. A movable plate 22 is fixedly connected to the push rod of the first electric push rod 21, and the output end of the motor drives the lead screw 19 to rotate. Simultaneously, the positioning rod 18 allows the reciprocating table 20 to move outside the lead screw 19 and the positioning rod 18. At the same time, the first electric push rod 21 on the reciprocating table 20 will also drive the movable plate 22 to move through its push rod. It should be noted that the direction of movement of the reciprocating table 20 is perpendicular to the direction of movement of the movable plate 22 driven by the push rod. Therefore, by working together with the push rod, the reciprocating table 20 drives the movable plate 22 to perform circular movement, so that the movable plate 22 drives the flame gun 26 to perform circular movement through the connecting long block 23, thereby improving the work quality when welding the pole post.

[0041] The bottom of the movable plate 22 is fixedly connected to a connecting block 23. The inside of the connecting block 23 is provided with two support L plates 24. The top of the support L plates 24 is fixedly connected to a connecting plate 25. The connecting block 23 drives the connecting plate 25 and the flame gun 26 to move through the support L plates 24. It should be noted that the support L plates 24 can be manually adjusted to move inside the connecting block 23. After moving to the appropriate position, they can be connected and fixed to the connecting block 23 with bolts to adjust the position of the flame gun 26 so that the position of the flame gun 26 corresponds to the position of the bowl-shaped mold 11.

[0042] A flame gun 26 is fixedly connected inside the connecting plate 25. A gas supply pipe 27 is fixedly connected to the top of the flame gun 26. The gas supply pipe 27 is connected to external equipment to deliver combustible gas to the flame gun 26 for use. The gas supply pipe 27 is relatively long, so when the flame gun 26 is in circular motion, the extra length of the gas supply pipe 27 is sufficient to meet its normal operation and will not affect the normal operation of the flame gun 26. The outside of the gas supply pipe 27 runs through the inside of the welding device frame 1. The flame gun 26 is used to weld the battery terminals, thereby welding the terminals and collar together. The inside of the flame gun 26 is also equipped with a valve to control the delivery of combustible gas. The flame gun 26 is a known technology, and those skilled in the art can and should understand its specific functions and structure. This utility model has not made any improvements, so it will not be described in detail here.

[0043] A motor is installed on one side of the top cover 17. The output end of the motor is fixedly connected to one end of the lead screw 19. Two lifting rods 28 are fixedly connected to the top of the top cover 17. The outside of the lifting rods 28 is sleeved with the inside of the welding device frame 1.

[0044] Two second electric push rods 29 are fixedly connected to the top of the cross plate 3, and the output end of the electric push rod is fixedly connected to the top of the lifting rod 28.

[0045] A nut is provided on the outside of the adjusting screw 7. The wedge positioning bracket 8 is connected and fixed to the outside of the screw through the nut. The position of the two wedge positioning brackets 8 can be manually adjusted according to the different distances between the two terminals of the battery. After adjustment, the wedge positioning bracket 8 is connected and fixed to the outside of the adjusting screw 7 through the nut.

[0046] A conveying equipment body 30 is provided on one side of the welding device frame 1. Two mounting blocks 31 are fixedly connected to the top of the conveying equipment body 30. A detector 32 is fixedly connected to the top of one of the mounting blocks 31. The detector 32 is a diffuse reflection photoelectric sensor. Its technology is currently very mature and well-known. Those skilled in the art can and should understand its specific functions and structure. It uses a light emitter to emit a light beam. When an object enters the sensing range, the light beam is diffusely reflected in all directions after hitting the object's surface. Part of the reflected light returns and is received by the light receiver. The receiver converts the light signal into an electrical signal. After circuit processing, it determines whether an object exists and then triggers an output signal to detect the object. Therefore, the detector 32 is used to detect the battery on the conveying equipment body 30. When the battery is detected, the cylinder 34 will work to position and intercept the battery. At the same time, the conveying equipment body 30 temporarily stops working, and then the battery terminals are welded.

[0047] Another mounting block 31 is fixedly connected to a mounting platform 33, and a cylinder 34 is fixedly connected to the top of the mounting platform 33. A fixing plate 35 is fixedly connected to the output end of the cylinder 34. The fixing plate 35 is moved by the piston rod of the output end of the cylinder 34, so that the fixing plate 35 can position and fix the battery. After the battery terminal welding is completed, the battery is released so that the battery can continue to be transported.

[0048] An automatic electrode welding device, the working principle of which is as follows:

[0049] First, the battery on the main body 30 of the conveying equipment is detected by the detector 32. When the battery is detected, the cylinder 34 will work to locate and intercept the battery. At the same time, the main body 30 of the conveying equipment will temporarily stop working. Then, the battery terminals will be welded.

[0050] Secondly, the output end of the hydraulic cylinder 14 pushes the cross plate 3 to descend, causing the cross plate 3 to drive the guide shaft 2, wedge positioning frame 8, and support platform 15 to descend as a whole. This allows the bowl-shaped mold 11 and positioning insert 12 to position and fix the battery terminals. Then, the flame gun 26 is used to weld the terminals. During the welding process, the output end of the second electric push rod 29 pushes the lifting rod 28 to drive the support platform 15 and other components, as well as the flame gun 26, to descend. This allows the flame gun 26 to approach the bowl-shaped mold 11 and continue welding the terminals. After the terminals are welded, the flame gun 26 is raised away from the bowl-shaped mold 11. Then, the guide shaft 2, wedge positioning frame 8, and support platform 15 are raised as a whole, and the battery can then be transported out of the welding device frame 1.

[0051] During the electrode welding process, the output end of the motor drives the lead screw 19 to rotate, and at the same time, the positioning rod 18 causes the reciprocating table 20 to move outside the lead screw 19 and the positioning rod 18. At the same time, the first electric push rod 21 on the reciprocating table 20 also drives the movable plate 22 to move through its push rod. It should be noted that the direction of movement of the reciprocating table 20 is perpendicular to the direction of movement of the movable plate 22 driven by the push rod. Therefore, by working together with the push rod, the reciprocating table 20 drives the movable plate 22 to perform circumferential movement, so that the movable plate 22 drives the flame gun 26 to perform circumferential movement through the connecting long block 23, thereby improving the work quality of electrode welding.

[0052] Finally, the piston rod at the output end of cylinder 34 pushes the fixed plate 35 to move, so that the fixed plate 35 releases the battery after the battery terminal welding work is completed, allowing the battery to continue to be transported.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
