Description

Technical Field

[0002] With the development of the concept of new energy and the emergence of new energy vehicles and other industries, batteries are becoming more and more important. Lithium batteries are a type of battery. In the process of lithium battery production and processing, it is necessary to weld the outer shell and other parts of the lithium battery. Lithium batteries are generally welded by laser welding. When the existing welding device is used to weld lithium batteries, the laser welding gun is prone to deflection during the welding process, resulting in misalignment of the welding position. The laser welding gun will cause damage to the components. At the same time, during welding, the laser will melt the metal at the welding point and bond them together. After the metal at the weld solidifies, it is prone to unevenness. Subsequent processing is required to keep the weld flat. In addition, the existing welding device cannot detect the welding effect, so it is impossible to determine the welding situation, resulting in the possibility of cracking of the components after welding, which is not conducive to welding.

[0032] After the driving motor 13 is started, its output end drives the rotating rod 63 to rotate, so that the first gear 64 fixedly sleeved on the rotating rod 63 rotates accordingly, driving the fixed gear ring 65 and the fixed cylinder 61 to rotate, so that the rotating cylinder 66 connected to the fixed cylinder 61 through the connecting support rod 67 rotates accordingly. When the rotating cylinder 66 rotates, the angular momentum generated by its self-rotation maintains a stable state to ensure that the rotating cylinder 66 and the laser welding gun 4 inside it can always be stable without angular deflection. At the same time, the rotation of the fixed cylinder 61 will rotate the grinding wheel 62, so that the grinding wheel 62 grinds the surrounding of the weld to keep the weld flat and avoid uneven welds. In addition, the rotation of the fixed gear ring 65 will rotate the second gear 68 meshing with it, so that the rotating shaft 610 rotates accordingly. The rotation of the rotating shaft 610 will drive the fixed fan 611 to rotate together, so that the vaporized metal and the metal particles generated by grinding are sucked into the inner side of the fixed tube 69 for cleaning.

[0033] like Figure 4 and Figure 6As shown, the detection structure 7 includes a worm sleeve 712 fixedly sleeved on the side wall of the fixed cylinder 61, and a connecting shaft 710 rotatably connected to the inner wall of the fixed shell 5 is installed on the rear side of the worm sleeve 712. A connecting worm wheel 711 meshing with the worm sleeve 712 is fixedly sleeved on the connecting shaft 710. The meshing relationship between the connecting worm wheel 711 and the worm sleeve 712 makes the rotation speed of the connecting worm wheel 711 slow, so that the knocking block 78 will not frequently knock on the weld, causing the weld to crack, and the inner wall of the fixed shell 5 is rotated to connect The fixing shaft 713 is connected to the connecting shaft 710, and the fixing shaft 713 penetrates the inner wall of the fixing housing 5 and extends to the inside of the connecting housing 9. The fixing shaft 713 and the connecting shaft 710 are connected to each other through a first belt transmission assembly 715. The fixing shaft 713 is located at one end of the inner side of the connecting housing 9 and is fixedly connected to a fixing cam 714. A fixing plate 71 is fixedly connected between the inner walls of the connecting housing 9, and the fixing plate 71 is installed above the fixing cam 714. The bottom end of the fixing plate 71 is slidably connected to a fixing rod 72, and the fixing rod 72 penetrates the fixing plate 71 and extends to the inside of the connecting housing 9. The bottom end of the fixing rod 72 is fixedly connected to the moving plate 73, the bottom end of the moving plate 73 is in contact with the top end of the fixed cam 714, a fixing spring 74 is fixedly installed between the moving plate 73 and the fixing plate 71, the bottom end of the moving plate 73 is fixedly connected to the fixing screw 75, the outer thread of the fixing screw 75 is sleeved with a screw sleeve 76, the bottom end of the screw sleeve 76 is provided with a groove, the inner wall of the groove is slidably connected with a connecting rod 77, the bottom end of the connecting rod 77 is fixedly connected to a knocking block 78, the top end of the connecting rod 77 A connecting spring is fixedly connected between the upper inner walls of the groove. Under normal conditions, the bottom wall of the knocking block 78 is located below the bottom end of the grinding wheel 62, and cooperates with the connecting spring 79 to enable the knocking block 78 to knock on the weld, and the elastic force of the connecting spring 79 can also prevent the knocking block 78 from being damaged. A collecting structure 8 is installed on the top of the fixed rod 72; the connection on the fixed screw 75 is rotatably connected with a damping ring, and the damping ring is fixedly connected to the top of the screw sleeve 76. The damping ring is a kind of damper, which can prevent the fixed screw 75 from automatically rotating.

[0034] When the fixed cylinder 61 rotates, the worm sleeve 712 fixedly sleeved on the outside thereof rotates accordingly, so that the connecting worm wheel 711 meshing with the worm sleeve 712 rotates, so that the connecting shaft 710 rotates together. Under the action of the first belt transmission assembly 715, the fixed shaft 713 and the fixed cam 714 rotate together. When the fixed cam 714 rotates, it squeezes the movable plate 73, so that the movable plate 73 moves upward, driving the fixed screw 75, the connecting rod 77 and the knocking block 78 to move accordingly, and at the same time causing the fixed spring 74 to contract. After the fixed cam 714 rotates, the elastic force of the fixed spring 74 Move the movable plate 73 downward, push the knocking block 78 to knock on the weld, and by observing whether the weld is cracked, the quality of welding can be judged. At the same time, since different positions have different requirements for welding, the screw sleeve 76 is rotated, and the screw sleeve 76 can be moved under the action of the thread, so as to adjust the distance between the screw sleeve 76 and the movable plate 73, so that the screw sleeve 76 is closer to the weld. When the knocking block 78 knocks on the weld, the contraction amount of the fixed spring 74 is greater, that is, the force of the fixed spring 74 is greater, so the force of the knocking block 78 knocking on the weld is greater, thereby improving the detection standard;

[0035] like Figure 7 , Figure 8 and Fig. 9As shown, the collecting structure 8 includes a cooling plate 81 slidably mounted inside the connecting shell 9, and an opening corresponding to the cooling plate 81 is opened on the side wall of the connecting shell 9. Metal particles and vaporized metal enter the connecting shell 9 through the fixed tube 69. After the vaporized metal contacts the cooling plate 81, it will condense into a solid. A screw sleeve 84 is rotatably connected to the inner wall of the connecting shell 9. The screw sleeve 84 penetrates the inner wall of the fixed shell 5 and extends into the interior of the fixed shell 5. The screw sleeve 84 is located at one end of the inner side of the fixed shell 5 and is connected to the fixed shaft 713 through a second belt drive assembly 85. The screw sleeve 84 is located at one end of the inner side of the connecting shell 9 and is slidably sleeved with a reciprocating screw 86. The end of the reciprocating screw 86 is slidably connected to a fixed scraper 83. The reciprocating screw 86 cannot rotate. The bottom end of the fixed scraper 83 is in close contact with the bottom wall of the cooling plate 81, and the fixed scraper 8 The side wall of the cooling plate 81 is slidably connected with a stabilizing block, the fixed scraper 83 and the stabilizing block can slide up and down, the stabilizing block is slidably connected with the inner wall of the connecting shell 9, the stabilizing block and the connecting shell 9 can slide left and right, the top of the fixed rod 72 is against the bottom end of the cooling plate 81, the side wall of the reciprocating screw rod 86 is fixedly connected with a sliding block 87, the side wall of the fixed scraper 83 is provided with a sliding groove 88 matching the sliding block 87, the top of the sliding block 87 is fixedly connected with a spring rod 89, the top of the spring rod 89 is fixedly connected with the inner wall of the sliding groove 88, the effect of the spring rod 89 is the same as that of an ordinary spring, and its elastic force enables the fixed scraper 83 to move up and down, and it is always in contact with the cooling plate 81 when moving up and down, the end of the cooling plate 81 passes through the opening, and the end of the cooling plate 81 is fixedly connected with a pulling plate 82, the pulling plate 82 can pull the cooling plate 81 out of the connecting shell 9 to recycle the metal;

[0036] Under the action of the second belt transmission assembly 85, the screw sleeve 84 rotates with the fixed shaft 713. Since the reciprocating screw 86 cannot rotate, the rotation of the screw sleeve 84 will cause the reciprocating screw 86 to move back and forth, thereby driving the fixed scraper 83 to move, scraping the cooling plate 81 and scraping off the metal adhering to the fixed scraper 83. At the same time, when the movable plate 73 moves up and down, the fixed rod 72 will move accordingly. The up and down movement of the fixed rod 72 will push the cooling plate 81 to move, causing the cooling plate 81 and the fixed scraper 83 to vibrate up and down, shaking up the metal on the cooling plate 81 and the fixed scraper 83, and further avoiding metal adhesion;

[0037] like Figure 3 As shown, a protrusion is fixedly connected to the rear side of the fixed housing 5, and an adjusting screw 11 is rotatably installed on the protrusion, and the adjusting screw 11 passes through the protrusion and is threadedly connected to the bracket plate 10; a fixed clamp is slidably installed on the top of the placement plate 3, and the position of the fixed housing 5 and the components inside it can be adjusted by adjusting the screw 11, so that the grinding wheel 62 can be pressed on the surface of the object to be welded, so as to facilitate the grinding of the grinding wheel 62;

[0038] like Figure 1 and Figure 2 As shown, a fixed clamp is slidably installed on the top of the placement plate 3 to fix the welding object;

[0039] like Fig.10 As shown, a moving motor is fixedly installed on one side wall of the moving platform 2, and a moving rod 14 is fixedly connected to the output end of the moving motor. A moving block 15 fixedly connected to the bottom end of the placement plate 3 is threadedly sleeved on the moving rod 14. After the moving motor is started, its output end drives the moving rod 14 to rotate, while the moving block 15 cannot rotate. Therefore, the rotation of the moving rod 14 will move the moving block 15 and the placement plate 3, so that the welding object moves accordingly, thereby performing automatic welding;

[0040] like Figure 1 and Figure 2 As shown, a control terminal is fixedly connected to the side wall of the workbench 1. The control terminal is a prior art. The laser welding gun 4, the driving motor 13 and the moving motor can be controlled through the control terminal.

[0041] In the present invention, the welded parts are first placed on the placement plate 3 and fixed by the fixing clamps. Then, the positions of the fixed housing 5 and the parts inside the housing are adjusted by adjusting the screw 11, so that the grinding wheel 62 can be pressed on the surface of the welded object to facilitate the grinding of the grinding wheel 62. When the moving motor is started, the output end of the moving motor drives the moving rod 14 to rotate, while the moving block 15 cannot rotate. Therefore, the rotation of the moving rod 14 will move the moving block 15 and the placement plate 3, so that the welding object moves accordingly, thereby performing automatic welding.

[0042] During welding, the laser welding gun 4 melts the metal at the welding point and welds them together. Part of the metal will be directly vaporized, and the weld will be uneven. During the welding process, the drive motor 13 is started. After the drive motor 13 is started, its output end drives the rotating rod 63 to rotate, so that the first gear 64 fixedly mounted on the rotating rod 63 rotates accordingly, driving the fixed gear ring 65 and the fixed cylinder 61 to rotate, and the rotating cylinder 66 connected to the fixed cylinder 61 through the connecting support rod 67 rotates accordingly. When the rotating cylinder 66 rotates, the angular momentum generated by its self-rotation maintains a stable state. , to ensure that the rotating cylinder 66 and the laser welding gun 4 inside it can be always stable without angle deflection. At the same time, the rotation of the fixed cylinder 61 will rotate the grinding wheel 62, so that the grinding wheel can grind the surrounding of the weld to keep the weld flat and avoid the weld being uneven. In addition, the rotation of the fixed gear ring 65 will rotate the second gear 68 meshing with it, so that the rotating shaft 610 rotates accordingly. The rotation of the rotating shaft 610 will drive the fixed fan 611 to rotate together, so that the vaporized metal and the metal particles generated by grinding are sucked into the inner side of the fixed tube 69;

[0043] At the same time, when the fixed cylinder 61 rotates, the worm sleeve 712 fixedly sleeved on the outside thereof rotates accordingly, so that the connecting worm wheel 711 meshing with the worm sleeve 712 rotates, so that the connecting shaft 710 rotates together. Under the action of the first belt transmission assembly 715, the fixed shaft 713 and the fixed cam 714 rotate together. When the fixed cam 714 rotates, it squeezes the movable plate 73, so that the movable plate 73 moves upward, driving the fixed screw 75, the connecting rod 77 and the knocking block 78 to move accordingly, and at the same time causing the fixed spring 74 to contract. After the fixed cam 714 rotates, the fixed spring 74 The elastic force causes the movable plate 73 to move downward, pushing the knocking block 78 to knock on the weld. By observing whether the weld is cracked, the quality of welding can be judged. At the same time, since different positions have different requirements for welding, the screw sleeve 76 is rotated, and the screw sleeve 76 can be moved under the action of the thread, thereby adjusting the distance between the screw sleeve 76 and the movable plate 73, so that the screw sleeve 76 is closer to the weld. When the knocking block 78 knocks on the weld, the fixed spring 74 contracts more, that is, the force of the fixed spring 74 is greater, so the knocking block 78 knocks on the weld with greater force, thereby improving the detection standard;

[0044] After the vaporized metal and metal particles enter the fixed tube 69, they will follow the fixed tube 69 into the connecting shell 9 and fall onto the cooling plate 81. After the vaporized metal contacts the cooling plate 81, it will condense into a solid. At this time, under the action of the second belt transmission assembly 85, the screw sleeve 84 rotates with the fixed shaft 713. Since the reciprocating screw 86 cannot rotate, the rotation of the screw sleeve 84 will cause the reciprocating screw 86 to move back and forth, thereby driving the fixed scraper 83 to move, scrape the cooling plate 81, and scrape off the metal adhered to the fixed scraper 83. At the same time, when the movable plate 73 moves up and down, the fixed rod 72 will move accordingly. The up and down movement of the fixed rod 72 will push the cooling plate 81 to move, causing the cooling plate 81 and the fixed scraper 83 to vibrate up and down, and vibrate the metal on the cooling plate 81 and the fixed scraper 83 to further avoid metal adhesion.
