DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] The utility model provides Figure 1-4The shown tool for assembling lithium batteries that is easy to weld includes a bottom plate 1 with a limited mounting groove 2 on the top, a dual-axis motor 3 is fixedly installed in the limited mounting groove 2, and an adjusting screw 4 is fixedly installed on the two output shafts of the dual-axis motor 3, and the two adjusting screws 4 are rotatably connected to the inner walls on both sides of the limited mounting groove 2. In order to rotatably install the adjusting screw 4 in the limited mounting groove 2, a rotating groove is respectively provided on the inner walls on both sides of the limited mounting groove 2, and the two ends of the two adjusting screws 4 extend into the two rotating grooves and are respectively fixedly sleeved with bearings, and the outer rings of the two bearings are respectively fixedly connected to the inner walls of the rotating grooves, and the adjusting screw 4 is made to rotate more stably in the limited mounting groove 2 through the bearings, and a limited connecting plate 5 is respectively threadedly installed on the two adjusting screws 4, and the tops of the two limited connecting plates 5 extend to the top of the limited mounting groove 2, and the tops of the two limited connecting plates 5 are respectively fixedly installed with a frame plate 7, and the two frame plates are fixedly mounted on the tops of the two limited connecting plates 5. Two limit slots 12 are respectively provided on the top of the plate 7, and a rotating rod 11 is respectively rotatably installed in the two frame plates 7, and the top ends of the two rotating rods 11 extend to the outside of the corresponding frame plates 7, and the bottom ends of the two rotating rods 11 are respectively fixed with a clamping plate 9, and a plurality of arc-shaped clamping openings 10 are respectively provided on the outer wall of the two clamping plates 9 close to each other. The arc-shaped clamping openings 10 greatly increase the clamping contact surface between the clamping plate 9 and the cylindrical lithium battery, which makes the clamping of the cylindrical lithium battery more stable, so that the cylindrical lithium battery always remains stable during welding, thereby improving the welding efficiency. A horizontal plate 13 is respectively fixedly installed on the top of the two rotating rods 11, and a rotating plate 14 is respectively provided above the two horizontal plates 13. Two card rods 15 are respectively slidably installed on the two horizontal plates 13, and the bottom ends of the four card rods 15 extend into the corresponding limit slots 12, and the top ends of the four card rods 15 are respectively fixedly connected to the corresponding rotating plates 14.
[0021] In order to ensure that one end of the card rod 15 is always located in the limit card slot 12 without being affected by other external forces, and thus the splint 9 is always stably maintained in the current position, compression springs 16 are fixedly installed on the top of the two horizontal plates 13. In order to improve the service life of the compression springs 16, the two compression springs 16 are tin-plated springs, and the top ends of the two compression springs 16 are fixedly connected to the corresponding rotating plates 14 respectively.
[0022] In order to limit the card rod 15 so that the card rod 15 is always slidably installed on the horizontal plate 13, and to prevent people from moving the card rod 15 due to excessive force, which may cause the card rod 15 to move out of the horizontal plate 13 and cause unnecessary trouble, a limiting circular plate 17 is fixedly sleeved on the two card rods 15.
[0023] In order to place the welded lithium batteries, two support rods 6 are fixedly installed on the top of the base plate 1, and a placement plate 8 is fixedly installed on the top of the two support rods 6. In order to increase the friction between the lithium battery and the placement plate 8, and thereby make the lithium battery placed on the placement plate 8 more stably, a number of friction stripes are opened on the placement plate 8, and the placement plate 8 passes through the two frame plates 7 and is movably connected to the two frame plates 7.
[0024] The working principle of the tooling for assembling lithium batteries for easy welding provided by the present invention is as follows: in the initial state, the compression spring 16 is in a compressed state, and one end of the clamping rod 15 is located in the limit clamping groove 12 to stably maintain the clamping plate 9 in the current position. When the cylindrical lithium battery needs to be welded, first place a number of cylindrical lithium batteries on the placement plate 8, start the dual-axis motor 3, and the dual-axis motor 3 rotates to drive the adjusting screw 4 to rotate. The adjusting screw 4 rotates to drive the two limit connecting plates 5 to approach each other. The two limit connecting plates 5 approach each other and drive the two frame plates 7 to approach each other. The two frame plates 7 approach each other and drive the two rotating rods 11 to approach each other. The two rotating rods 11 approach each other and drive the two clamping plates 9 to approach each other so that the arc-shaped clamping opening 10 contacts the cylindrical lithium battery. The arc-shaped clamping opening 10 greatly increases the clamping contact surface between the clamping plate 9 and the cylindrical lithium battery, which clamps the cylindrical lithium battery. After the clamping plate 14 is released, the clamping rod 15, the horizontal plate 13 and the rotating rod 11 are rotated, and then the clamping plate 9 is finally driven to rotate, so that the two planar clamping surfaces on the clamping plate 9 are in a relative state, and then the rotating plate 14 is released and the clamping rod 15 is pulled into the limit slot 12 again under the action of the compression spring 16 to keep the clamping plate 9 stably in the current state, and then the dual-axis motor 3 is started to rotate and drive the adjusting screw 4 to rotate. The adjusting screw 4 rotates and drives the two clamping plates 9 to approach each other to clamp and fix the rectangular lithium battery with a flat surface, so that people can perform rectangular welding on the rectangular lithium battery.
[0025] Compared with the related art, the lithium battery assembly tool provided by the present invention that is easy to weld has the following beneficial effects:
[0026] The utility model provides a tool for assembling lithium batteries that is convenient for welding. A plurality of cylindrical lithium batteries are placed on the placement plate 8, and the two clamping plates 9 are driven by the dual-axis motor 3 to rotate and drive the two clamping plates 9 to approach each other so that the arc-shaped clamping opening 10 contacts the cylindrical lithium batteries. The arc-shaped clamping opening 10 greatly increases the clamping contact surface of the clamping plate 9 and the cylindrical lithium batteries, so that the cylindrical lithium batteries are clamped more stably, and the cylindrical lithium batteries are always kept in a stable state during welding, thereby improving welding efficiency. By placing the rectangular lithium battery on the placement plate 8, the rotating plate 14 is moved upward to drive the clamping rod 15 to move upward and leave the limit clamping groove 12, and the rotating plate 14 is rotated 180 degrees so that the two flat clamping surfaces on the clamping plates 9 are in a relative state, and then the rotating plate 14 is released, and the clamping rod 15 is pulled into the limit clamping groove 12 again under the action of the compression spring 16 to stably maintain the clamping plates 9 in the current state, and the dual-axis motor 3 is started again to rotate and drive the two clamping plates 9 to approach each other to clamp and fix the rectangular lithium battery with a flat surface, so that people can perform rectangular welding on the rectangular lithium battery.
