Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery assembly, in particular to a limiting device for lithium battery assembly. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use place very high demands on the environment. With the advancement of technology, lithium batteries have been widely used and promoted, becoming a mainstream product in the mobile power supply industry. During the processing of lithium batteries, they are generally assembled, and during this process, they require the use of fixtures to secure them for convenient operation.

[0003] However, when assembling lithium batteries, most of them are placed horizontally on a workbench and then assembled. This makes it easy for workers to move the lithium batteries during the assembly process. Usually, a limit device is set to block the batteries. However, when assembling lithium batteries of different shapes, traditional clamping devices are difficult to achieve stable clamping, which affects the clamping effect. For this reason, we propose a limit device for lithium battery assembly to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a limiting device for lithium battery assembly.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] Preferably, one end of the screw rod passes through one end of the support frame, and a rotating block is fixed to one side of the screw rod.

[0008] Preferably, a rubber sleeve is provided on the outer side wall of the rotating block.

[0009] Preferably, the clamping block is fixed to the upper end of the connecting plate by two screws.

[0010] Preferably, a rubber layer is provided on one side of the clamping block.

[0011] Preferably, two clamping plates are fixed to one end of the two connecting plates on the same side.

[0012] In the present invention, when lithium batteries need to be assembled, the corresponding multiple groups of battery blocks are placed on the operating table. The operator presses the switch to send a signal to control the servo motor to start, which rotates to the corresponding formation, drives the screw to rotate, and realizes the movement of the two moving blocks in the direction of the rotating block, and then realizes the contraction of the folding frame, driving the two mounting blocks to move toward the middle at the same time. As the mounting blocks move, the clamping blocks are driven to move toward the middle through the connecting plate to achieve full clamping of the lithium batteries. When lithium batteries of different specifications need to be assembled, the position of the clamping plate and the clamping block can be adjusted by adjusting the position of the nut on the stud. Figure 4 As shown, it can meet the assembly requirements of lithium batteries of different specifications and shapes.

[0013] The utility model can not only realize stable clamping during the assembly of lithium batteries, ensuring the adequacy and stability of the assembly, but also can adapt to the assembly needs of lithium batteries of different specifications and shapes, and can adjust the clamping position according to their shape and size, fully improving the adaptability and enhancing the convenience and flexibility of use.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1

[0022] Reference Figure 1-4 A limiting device for lithium battery assembly includes a bottom plate 13, a support frame 6 is fixed to the middle of the upper end of the bottom plate 13, a screw rod 2 is rotatably sleeved on the support frame 6, one end of the screw rod 2 passes through one end of the support frame 6, and a rotating block 7 is fixed to one side of the screw rod 2. The rotating block 7 can be manually adjusted in an emergency situation to facilitate emergency operation. A rubber sleeve is sleeved on the outer wall of the rotating block 7;

[0023] A servo motor 1 is fixed to one side of the support frame 6. The output shaft of the servo motor 1 is connected to one end of the screw 2. The rotation of the output shaft of the servo motor 1 drives the screw 2 to rotate, thereby realizing the movement of the moving block 8, and then realizing the adjustment of the structures at both ends;

[0024] Two moving blocks 8 are threadedly sleeved on the screw rod 2. The upper end of the moving block 8 is rotatably connected to two folding frames 3, and the two folding frames 3 are rotatably connected to each other. One end of the two folding frames 3 on the same side is rotatably connected to a mounting block 5. Studs 4 are fixed to both ends of one side of the mounting block 5. A connecting plate 10 and two nuts 9 are provided through the studs 4. Two nuts 9 clamp a connecting plate 10 to ensure the stability and firmness of its installation. The position of the connecting plate 10 is adjusted by the nuts 9 to fully meet the assembly and clamping requirements of lithium batteries of different shapes.

[0025] The two nuts 9 on the same side respectively abut against the two sides of a connecting plate 10, and support columns 14 are fixed to the four corners of the upper end of the base plate 13. The upper end of the support column 14 is fixed to an operating table 11, and two slots 12 are provided on the operating table 11. The two connecting plates 10 on the same side respectively pass through the two ends of the slot 12 and extend to the upper end of the operating table 11. A clamping block 15 is fixed to one side of the upper end of the connecting plate 10, and the two clamping blocks 15 in the same direction are opposite to each other. The clamping block 15 is fixed to the upper end of the connecting plate 10 by two screws. A rubber layer is provided on one side of the clamping block 15. The clamping block 15 can achieve fully stable clamping to ensure the stability and speed of clamping.

[0026] Example 2

[0027] Reference Figure 5The difference between this embodiment 2 and embodiment 1 is that this embodiment 2 also includes two clamping plates 16 fixed to one end of the two connecting plates 10 on the same side. Through the setting of the clamping plates 16, large workpiece parts can be clamped, thereby improving the application range of clamping and further improving uniformity.

[0028] In the present invention, when lithium batteries need to be assembled, the corresponding multiple groups of battery blocks are placed on the operating table 11. The operator presses the switch to send a signal to control the servo motor 1 to start, which rotates to the corresponding formation, drives the screw 2 to rotate, and realizes the movement of the two moving blocks 8 in the direction of the rotating block 7, and then realizes the contraction of the folding frame 3, driving the two mounting blocks 5 to move toward the middle at the same time. As the mounting blocks 5 move, the clamping block 15 is driven to move toward the middle through the connecting plate 10 to achieve full clamping of the lithium batteries. When lithium batteries of different specifications need to be assembled, the position of the clamping plate 10 and the clamping block 15 can be adjusted by adjusting the position of the nut 9 on the stud 4. Figure 4 As shown, it can meet the assembly requirements of lithium batteries of different specifications and shapes.
