[0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and non-aqueous electrolyte solution. With the rapid development of science and technology, lithium batteries have been widely promoted and applied. In the processing of multi-stage modular lithium batteries, they need to be assembled by assembly equipment; such as a lithium battery assembly device with application number CN211529985U, including support feet, positioning components, brackets, clamping components, electric control cabinets, PLC controllers and displays. By setting the positioning components, when the battery lower cover is placed in the positioning groove, the positioning column plays a positioning role on the battery lower cover to ensure that the battery lower cover is accurately positioned.

[0003] The above utility model has the following shortcomings: when applied to a multi-stage modular lithium battery, when multiple multi-stage modular lithium batteries are placed on the battery lower cover for assembly, due to the smoothness of the lower battery cover, the multiple multi-stage modular lithium batteries are easy to move, resulting in inconsistent heights of the assembled multi-stage modular lithium batteries, thereby affecting the assembly effect of the multi-stage modular lithium battery. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a multi-stage modular lithium battery assembly device.

[0005] According to the technical solution provided in the embodiments of this application,

[0006] A multi-stage modular lithium battery assembly equipment, wherein bottom columns are installed at the corners of the bottom end of the operating table, a frame is vertically installed at the top edge of the operating table, a built-in cavity is dug inside the operating table, a power box is installed in the middle of the bottom end of the operating table, a PLC controller is installed on the right side of the operating table, a control panel is mounted on the front side of the operating table, a storage slot is dug in the middle of the upper end of the operating table, a slide slot and a limit slot are dug at the upper end of the operating table and on the left and right sides of the storage slot, vertical plates are suspended on both sides of the upper end of the operating table, a group of electric control lifting rods are installed at the top of the frame, and a lower pressure plate is horizontally installed at the telescopic end of the electric control lifting rod. The pressure plate corresponds to the storage slot and is located on the same horizontal line. Positioning rods are installed at the inner corners of the storage slot, and a bidirectional motor is installed in the middle of the built-in cavity. The two ends of the bidirectional motor are respectively rotated and installed with screw rods. The two screw rods are equipped with screw barrels that are compatible with the threaded transmission set. The slide groove is connected to the built-in cavity. The limit grooves are grouped in two and are distributed correspondingly front and back. The slide groove is installed between the limit grooves adjacent to the front and rear. A lower support plate is installed in the middle of the bottom end of the vertical plate, and limit rods are installed on the front and rear sides of the bottom end of the vertical plate. A damping member and a plurality of evenly distributed high-pressure springs are installed on the opposite side of the vertical plate.

[0007] Furthermore, the lower support plate extends into the slide groove and is connected with the screw barrel, and the limiting rods extend into the corresponding limiting grooves and are slidably connected.

[0008] Furthermore, the other ends of the high-pressure spring and the damping member are jointly mounted with a clamping plate.

[0009] Furthermore, a pressure sensor is installed in the middle of the clamping plate.

[0010] Furthermore, the pressure sensor is connected to the control panel and the PLC controller respectively by means of sensing control lines.

[0011] Furthermore, the power box is connected to the control panel, PLC controller and other electrical components through wire lines.

[0012] In summary, the beneficial effects of this application are:

[0013] 1. Through the arrangement of a bidirectional motor, a lead screw, a screw barrel, a vertical plate and a clamping plate, the bidirectional motor drives the lead screw to rotate forward, and the screw barrels on the two lead screws drive the vertical plate to approach the multi-stage modular lithium battery on the storage slot through the lower support rod until the clamping plate contacts the left and right sides of the multi-stage modular lithium battery. The multi-stage modular lithium battery can remain stable during the assembly process, and the heights of the multi-stage modular lithium batteries are consistent. A high-pressure spring and a damping member are installed between the clamping plate and the vertical plate. The clamping plate adheres to the multi-stage modular lithium battery, which can generate a force to achieve buffering and shock absorption, avoid excessive clamping of the clamping plate, and cause damage to the multi-stage modular lithium battery. At the same time, a pressure sensor is installed on the clamping plate, and the pressure can be monitored in real time through the PLC controller, effectively avoiding the pressure value from exceeding the standard value, improving practical performance, and further improving the assembly quality of the multi-stage modular lithium battery.

DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a multi-stage modular lithium battery assembly equipment is provided, wherein a bottom column 101 is arranged at the corner of the bottom end of an operating table 1, a frame 102 is vertically arranged at the top edge of the operating table 1, a built-in cavity 5 is excavated inside the operating table 1, a power box 18 is installed in the middle of the bottom end of the operating table 1, a plc controller 16 is installed on the right side of the operating table 1, a control panel 17 is mounted on the front side of the operating table 1, a storage groove 4 is excavated in the middle of the upper end of the operating table 1, a positioning rod 401 is arranged at the inner corner of the storage groove 4, a slide groove 9 and a limit groove 11 are excavated at the upper end of the operating table 1 and on the left and right sides of the storage groove 4, vertical plates 10 are suspended on both sides of the upper end of the operating table 1, a group of electric control lifting rods 2 are installed at the top of the frame 102, and the telescopic end of the electric control lifting rod 2 is horizontally installed below A pressure plate 3 and a bidirectional motor 6 are installed in the middle of the built-in cavity 5, and screw rods 7 are respectively rotated and installed at both ends of the bidirectional motor 6. The two screw rods 7 are both equipped with screw barrels 8 that are compatible with the threaded transmission set. A lower support plate 1001 is installed in the middle of the bottom end of the vertical plate 10, and limit rods 1002 are installed on the front and rear sides of the bottom end of the vertical plate 10. A damping member 13 and a plurality of evenly distributed high-pressure springs 12 are installed on the opposite side of the vertical plate 10. The other ends of the high-pressure springs 12 and the damping member 13 are jointly installed with a clamping plate 14, and a pressure sensor 15 is installed in the middle of the clamping plate 14. The lower support plate 1001 extends into the slide groove 9 and is connected with the screw barrel 8, and the limit rods 1002 respectively extend into the corresponding limit grooves 11 and are slidably connected.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, when in use, the lower cover is laid flat in the storage slot 4, and the positioning rod 401 supports and limits it. Multiple multi-stage modular lithium batteries are installed vertically and placed side by side on the lower cover in turn. At this time, the bidirectional motor 6 in the built-in cavity 5 drives the screw rod 7 to rotate forward, and the screw barrel 8 on the two screw rods 7 drives the vertical plate 10 to approach the multi-stage modular lithium battery through the lower support rod 1001 until the clamping plate 14 conflicts with the left and right sides of the multi-stage modular lithium battery. The multi-stage modular lithium battery can remain stable during the assembly process and keep the same height. The limiting rod 1002 on the lower side of the vertical plate 10 extends into the corresponding limiting groove, thereby assisting the vertical plate 10 to be stable in left and right translation. At the same time, the bottom end of the vertical plate 10 can remain upright under the support of the lower support plate 1001 and the limiting rod 1002 to avoid tilting forward and backward. A pressure sensor 15 is installed on the clamping plate 14, and the pressure can be monitored and adjusted in real time through the PLC controller 16 and the control panel 17, thereby improving the assembly quality of the multi-stage modular lithium battery.

[0023] like Figure 1 and Figure 2 As shown, after the preliminary assembly of multiple multi-stage modular lithium batteries is completed, the electric-controlled lifting rod 2 is started through the control panel 17 to move the lower pressure plate 3 downward until the cover is installed on the top of the assembled multi-stage modular lithium battery, and then the bidirectional motor 6 is started for the second time through the control panel 17. The bidirectional motor 6 drives the screw rod to reverse, and the vertical plate 10 and the clamping plate 14 are driven by the screw barrel 8 to move away from the multi-stage modular lithium battery, and finally the assembly and cover installation of multiple multi-stage modular lithium batteries are completed. The staff takes them out and then repeats the above steps to carry out a new round of multi-stage modular lithium battery assembly and processing. During the entire assembly process, the power box 18 provides power support for the entire device to ensure that the multi-stage modular lithium battery assembly can operate normally.
