Description

Technical Field

[0001] This invention relates to the field of energy storage battery welding technology, specifically to a novel rapid welding assembly for energy storage batteries. Background Technology

[0002] The connection reliability, conductivity, heat dissipation efficiency, and safety stability of batteries are all important considerations. The welding objects of energy storage batteries mainly include cell tabs and busbars. The tabs are mostly made of aluminum (positive electrode), copper (negative electrode), or copper plated with nickel. The core goal of welding is to achieve a low-resistance, high-strength metallurgical bond between the tabs and the busbars / connectors without damaging the cell body. Common welding processes need to be selected based on the cell type, structure, and mass production requirements. Laser welding machines use a high-energy laser beam to focus on the welding area, instantly melting the metal to form a molten pool. In existing technologies, rapid welding components for energy storage batteries have certain drawbacks. Laser welding machines produce small particles of slag when welding electrode ears. These particles splash irregularly, and the high-temperature slag can easily burn operators, causing injury to workers. If the fixture positioning accuracy is insufficient or the cell loading is off-center, the electrode ears are often thin and have slight positioning deviations. The welding head is very prone to colliding with the rigid battery casing. There is a lack of components to protect the end of the welding head. Therefore, a new type of rapid welding component for energy storage batteries is proposed. Summary of the Invention

[0010] As a preferred embodiment of the present invention, a closing assembly is detachably installed at the bottom of the connecting plate. The closing assembly includes a second fixing plate, which is installed at the bottom of the connecting plate. The second fixing plate is connected to a third fixing plate via fixing bolts. A plurality of closing blocks are provided between the second fixing plate and the third fixing plate. A second actuating pin is threadedly connected to the middle of the upper surface of each closing block. A connecting pin is installed at the end of the closing block. The connecting pin is slidably connected to the second fixing plate and the third fixing plate. The second actuating pin is slidably connected to the second fixing plate.

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1:

[0020] Please see Figure 1 - Figure 5As shown, a novel rapid welding assembly for energy storage batteries includes a welding machine base 1 and a column 2. The column 2 is located at the top of the welding machine base 1. A rotary motor 3 is mounted on the surface of the column 2, and a lifting column 4 and a welding head 5 are mounted at the end of the rotary motor 3. The welding head 5 is located at the bottom of the lifting column 4. The rotary motor 3 can rotate the lifting column 4 and the welding head 5, thereby adjusting the angle of the end of the welding head 5. Similarly, the welding head 5 can be raised and lowered along the lifting column 4 to adjust its position, so that the welding head 5 can be directly facing the electrode plates of the battery. A protective component 6 is provided at the top of the welding head 5 and at the intersection of the welding head 5 and the lifting column 4. The protective component 6 includes a first fixing plate 61, on which the welding head is welded. At the top of component 5, a connecting block 63 is provided inside the first fixing plate 61. The upper end of the connecting block 63 is slidably connected to the inside of the first fixing plate 61. The bottom end of the protective component 6 contacts the electrode plate of the battery, causing the first fixing plate 61 and the connecting block 63 to slide relative to each other. A fixed base 66 is connected to the bottom end of the connecting block 63. The connecting block 63 and the fixed base 66 rotate relative to each other. A connecting plate 68 is welded to the bottom end of the fixed base 66. The connecting plate 68 is used to prevent welding slag from splashing when the welding head 5 welds the electrode plate of the battery. The fixed base 66 and the connecting block 63 are assembled together. The fixed base 66 and the connecting plate 68 rotate synchronously. The opening direction of the connecting plate 68 is to face the electrode plate of the battery to avoid welding slag splashing to the workers when the welding head 5 contacts the electrode plate.

[0021] Please see Figure 3 and Figure 4 As shown, a mating groove 62 is provided on the surface of the first fixing plate 61 at the intersection of the first fixing plate 61 and the connecting block 63. The connecting block 63 moves up and down along the mating groove 62 of the first fixing plate 61. When the protective component 6 contacts, the connecting block 63 can move up and down normally. A reserved groove 64 is provided on the surface of the connecting block 63 at the intersection of the first fixing plate 61 and the connecting block 63. A telescopic spring 65 is provided inside the reserved groove 64. One end of the telescopic spring 65 is connected to the first fixing plate 61, and the other end of the telescopic spring 65 is connected to the bottom end of the reserved groove 64. The telescopic spring 65 is used to keep the fixed base 66 pressed against the surface of the battery. When the bottom end of the protective component 6 contacts the electrode plate of the battery, the telescopic spring 65 can be compressed. When the telescopic spring 65 is compressed, the connecting block 63 moves relative to the first fixing plate 61. When the bottom end of the protective component 6 separates from the electrode plate of the battery, the connecting plate 68 is lowered under the action of the telescopic spring 65 to protect the welding head 5.

[0022] Please see Figure 3 and Figure 4As shown, a fixing hoop 67 is provided at the intersection of the bottom end of the connecting block 63 and the top end of the fixed base 66. The fixing hoop 67 is used to limit the connecting block 63 and the fixed base 66 to each other. The relative rotation of the connecting block 63 and the fixed base 66 is used to rotate the fixed base 66 to the direction of welding slag spatter. The bottom end of the connecting block 63 and the top end of the fixed base 66 are limited by the fixing hoop 67, so that the connecting block 63 and the fixed base 66 will not separate. Similarly, the connecting block 63 can rotate relative to the fixed base 66. Before welding, the opening direction of the connecting plate 68 can be aligned with the electrode plate of the battery in advance, so as not to affect the welding head 5 to weld the battery plate. Alternatively, the connecting plate 68 can rotate freely after contacting the battery terminal, without affecting the welding head 5 to move freely for welding.

[0023] Please see Figure 4 and Figure 5 As shown, a rotating disk 610 is slidably connected inside the connecting disk 68. Both the connecting disk 68 and the rotating disk 610 are truncated cones, and the truncated cone shape of the connecting disk 68 matches the truncated cone shape of the rotating disk 610. The rotating disk 610 can be inserted into the interior of the connecting disk 68, so that the rotating disk 610 and the connecting disk 68 rotate relative to each other. The connecting disk 68 is welded to the bottom of the fixed base 66. The relative rotation of the connecting disk 68 and the rotating disk 610 is used to assemble the connecting disk 68 and the rotating disk 610 into a complete truncated cone shape. The welding head 5 is located in the middle of the connecting disk 68 and the rotating disk 610. When welding, the welding head 5 can block the welding slag through the connecting disk 68, or the welding slag can be blocked through the connecting disk 68 and the rotating disk 610. When welding is not required, the connecting disk 68 and the rotating disk 610 are staggered to protect the welding head 5. The connecting disk 68 can not only prevent welding slag from splashing onto the workers, but also prevent the welding head 5 from being damaged or impacted.

[0024] Please see Figure 4 and Figure 5 As shown, the connecting plate 68 has a reserved cavity 69 inside, and the rotating plate 610 is located inside the reserved cavity 69. The rotating plate 610 is slidably connected to the inside of the reserved cavity 69. The generatrix taper of the reserved cavity 69 corresponds to the generatrix taper of the rotating plate 610, so that the rotating plate 610 can be normally inserted into the inside of the reserved cavity 69. The fixed base 66 has a first sliding groove 611 inside. The top of the rotating plate 610 and located inside the fixed base 66 are welded with a first actuating pin 612. The inside of the first sliding groove 611 is slidably connected to the first actuating pin 612. When the first actuating pin 612 slides along the inside of the first sliding groove 611, it can move the rotating plate 610 along the inside of the reserved cavity 69 of the connecting plate 68, so that the connecting plate 68 and the rotating plate 610 can be opened or closed relative to each other.

[0025] Please see Figure 5As shown, the first actuating pin 612 consists of two fixing pins arranged in a cross shape, with the thinner fixing pin being fixed to the thicker fixing pin by a thread. The cross-sectional shape of the first sliding groove 611 is arranged in a cross shape, allowing the first actuating pin 612 to be installed inside the first sliding groove 611. The first actuating pin 612 is used to rotate the rotating disk 610 relative to the reserved cavity 69. The central angle of the connecting disk 68 ranges from 120° to 135°, and the central angle of the rotating disk 610 ranges from 60° to 75°. The central angles of the connecting disk 68 and the rotating disk 610 are used to ensure that the connecting disk 68 and the rotating disk 610 are assembled into a frustum shape. The central angles of the connecting disk 68 and the rotating disk 610 can ensure that the connecting disk 68 and the rotating disk 610 are completely closed, or that the battery terminals can be placed inside the connecting disk 68 after the connecting disk 68 is opened.

[0026] It should be noted that after placing the battery on the worktable of the welding machine base 1, adjusting the front-back and left-right positions of the worktable, and rotating the motor 3 to align the end of the welding head 5 with the electrode plate of the battery, the lifting column 4 is used to move the welding head 5 to the appropriate position and height. The adjusted welding head 5 can then weld the electrode plate. The protective component 6 can protect the area around the electrode plate. Specifically, when the lifting column 4 rises or falls, the connecting plate 68 contacts the battery casing, which in turn drives the connecting block 63 and the fixed base 66 to rise or fall. The connecting block 63 slides relative to the mating groove 62 of the first fixed plate 61, compressing the telescopic spring 65 in the reserved groove 64. At this time, it will not affect the welding head 5. When welding electrode sheets with welding head 5, some welding slag will splash out when welding head 5 contacts the electrode sheet. Since the welding slag is small, it can slide down along the inner wall of connecting plate 68 and rotating plate 610 without affecting the electrode sheet in the middle of connecting plate 68. In order to prevent welding slag from splashing to the outside, the opening direction of connecting plate 68 can be adjusted in advance. Welding slag can only splash out from the opening direction of connecting plate 68 and will not splash out from connecting plate 68 and injure the workers. By moving the first actuating pin 612 along the inside of the first sliding groove 611, the rotating plate 610 is rotated from the reserved cavity 69 of connecting plate 68. Thus, connecting plate 68 and rotating plate 610 can be assembled into a whole frustum shape, so that welding slag will not splash out when welding electrode sheets.

[0027] Please see Figure 2 , Figure 6 - Figure 8As shown, a closure assembly 7 is detachably installed at the bottom of the connecting plate 68. The closure assembly 7 includes a second fixing plate 71, which is installed at the bottom of the connecting plate 68. The closure assembly 7 can be installed at the bottom of the connecting plate 68. The lower part of the second fixing plate 71 is connected to a third fixing plate 72 by fixing bolts 79. A plurality of closing blocks 73 are provided between the second fixing plate 71 and the third fixing plate 72. The closing blocks 73 can be installed between the second fixing plate 71 and the third fixing plate 72, so that the closing blocks 73 can be adjusted between the second fixing plate 71 and the third fixing plate 72. Each closing block 73 has a second actuating pin 74 threadedly connected to the middle of its upper surface. A connecting pin 76 is installed at the end of the closing block 73. The connecting pin 76 is slidably connected to the second fixing plate 71 and the third fixing plate 72. The second actuating pin 74 is slidably connected to the second fixing plate 71. The closing block 73 is used to expose or close the welding head 5 inside the connecting plate 68 for work or for protection. The connecting pin 76 of the closing block 73 slides inside the third sliding groove 77. By moving some of the second actuating pins 74, the position of the closing block 73 can be changed, and the size of the closing of the closing block 73 can be adjusted.

[0028] Please see Figure 6 - Figure 8 As shown, the closing blocks 73 are arranged in a circular array, and the sum of the angles of the tips of all closing blocks 73 is 360°. The tips of the closing blocks 73 are close to the center of the second fixed plate 71, which can close the second fixed plate 71. The second sliding grooves 75 and the third sliding grooves 77 are also arranged in a circular array. The directions of the second sliding grooves 75 and the third sliding grooves 77 are intersected. The connecting pin 76 and the second actuating pin 74 are used to control the position of the closing blocks 73. When the tips of the closing blocks 73 move closer to the center of the second fixed plate 71, the second fixed plate 71 is closed. When not in use, it can protect the welding head 5 from damage. When the tips of the closing blocks 73 move closer to the edge of the second fixed plate 71, the second fixed plate 71 is opened, and the welding head 5 can be exposed from the second fixed plate 71 for operation.

[0029] Please see Figure 7 and Figure 8 As shown, the surfaces of the second fixing plate 71 and the third fixing plate 72 are provided with several pairs of corresponding connecting holes 78. The fixing bolts 79 are located inside the connecting holes 78 of the second fixing plate 71 and the third fixing plate 72. The length of the fixing bolts 79 is greater than the sum of the thickness of the second fixing plate 71, the thickness of the third fixing plate 72 and the thickness of the closing block 73. Each closing block 73 can be placed between the second fixing plate 71 and the third fixing plate 72. Then the fixing bolts 79 pass through the second fixing plate 71 and the third fixing plate 72, so that the second fixing plate 71, the third fixing plate 72 and the closing block 73 will not be separated, and the closing block 73 can rotate normally between the second fixing plate 71 and the third fixing plate 72.

[0030] Please see Figure 7 and Figure 8 As shown, the bottom end of the connecting plate 68 has several threaded holes, each threaded hole corresponding to the connecting hole 78. The end of the fixing bolt 79 passes through the inside of the connecting hole 78 and is fixed to the threaded hole of the connecting plate 68. The second fixing plate 71 is detachably installed with the connecting plate 68 by means of the fixing bolt 79. The fixing bolt 79 can be passed through the third fixing plate 72 and the second fixing plate 71, and then the end of the fixing bolt 79 can be screwed into the bottom end of the connecting plate 68 for fixation. The closing component 7 can be fixed to the bottom end of the connecting plate 68.

[0031] It should be noted that when welding the battery electrode plates, the welding head 5 needs to be exposed from inside the second fixing plate 71. Specifically, by manually moving one of the second actuating pins 74, the second actuating pin 74 moves along the second sliding groove 75, causing the connecting pin 76 on the closing block 73 to move along the third sliding groove 77. As a result, the tips of each closing block 73 move closer to the edge of the second fixing plate 71. The closing block 73 will not affect the exposure of the welding head 5 from the second fixing plate 71. Alternatively, the fixing bolts 79 on the second fixing plate 71 can be removed from the connecting plate 68. The bottom end is disassembled to separate the closing component 7 from the connecting plate 68, without affecting the welding head 5 from the inside of the second fixing plate 71 to expose the welding electrode piece; when the electrode piece of the battery does not need to be welded, the closing component 7 is installed at the bottom end of the connecting plate 68, and then the second toggle pin 74 is moved to change the position of the closing block 73. The connecting pin 76 slides along the inside of the third sliding groove 77, so that the tip of the closing block 73 moves closer to the center, and the welding head 5 can be stored inside the closing component 7. When not in use, the battery casing will not hit the welding head 5.

[0032] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
