The following embodiments are used to illustrate the present invention.

[0041] Example 1

[0042] like Figures 1 to 8 As shown, a modular lithium battery includes: an all-plastic casing 100, which includes a plastic casing base at the bottom; multiple battery cells are installed inside the all-plastic casing 100; each battery cell includes a battery core 101; an insulating layer 102 is installed on the outside of the battery core 101; and a fireproof and heat-insulating layer is also provided inside the all-plastic casing 100; a sub-positive electrode assembly 103 is disposed at one end of the battery core 101; a sub-negative electrode assembly 109 is disposed at the other end of the battery core 101; and multiple battery cells are connected at both ends to separate connecting plates 115, which are connected by an integrated connecting plate 114.

[0043] like Figures 5 to 7As shown, in a specific embodiment, the sub-positive electrode assembly 103 includes a first insulating ring 104, inside which a positive electrode panel 105 is installed. A pure aluminum electrode post 106 is installed at one end of the positive electrode panel 105. A sealing nail 107 is also provided at one end of the sub-positive electrode assembly 103, and a sealing aluminum nail 108 is installed at one end of the sealing nail 107. The sub-negative electrode assembly 109 includes a second insulating ring 110, inside which a negative electrode panel 111 is installed.

A temperature acquisition device 118 and a voltage acquisition device 119 are also installed on the top of the all-plastic casing 100. In this configuration, the temperature acquisition device 118 is used to acquire the temperature of the battery cells, and the voltage acquisition device 119 is used to acquire the voltage of the battery cells.

[0045] Example 2

[0046] like Figures 9 to 14 As shown, a production equipment for packaging modular lithium batteries includes a feeding unit, which includes a lifting mechanism. A mounting platform 208 is mounted on the bottom of the lifting mechanism, and a feeding component is provided on the side of the mounting platform 208. The feeding component includes a clamp 210, and a negative pressure component is provided on one side of the clamp 210. The mounting unit includes a workbench 300, a support plate 303 is provided on the top of the workbench 300, a sliding component is rotatably mounted on the top of the support plate 303, and a guide component is provided at the bottom of the sliding component. The guide component includes a guide post 309 and a guide groove 310. The guide groove 310 is fixedly mounted on the top of the support plate 303, and a clamping component is provided on the top of the sliding component. When the sliding component rotates, the guide post 309 and the guide groove 310 drive the clamping component to slide on the sliding component.

[0047] There are three chucks 210, which are distributed on the three sides of the mounting platform 208. The directions of two adjacent chucks 210 are perpendicular to each other. The normal of the guide groove 310 at the corresponding point of the chuck 210 passes through the rotation center of the sliding component, so that the direction of the clamping component is aligned with the chuck 210 when it rotates to the corresponding point. The distance between the guide groove 310 and the rotation center of the sliding component is different at different points.

[0048] like Figures 9 to 10As shown, in a specific embodiment, the lifting mechanism includes a hydraulic cylinder 201. A sleeve 202 is installed at the output end of the hydraulic cylinder 201. A support column 203 is movably inserted into the sleeve 202. A meshing assembly is provided on one side of the support column 203. The meshing assembly includes a toothed groove 204 formed on the support column 203 and a toothed plate 205 that meshes with the toothed groove 204. A fixing plate 206 is fixedly installed on one side of the toothed plate 205. The fixing plate 206 is fixedly connected to one side of the hydraulic cylinder 201. A sliding device 200 is installed on the top of the hydraulic cylinder 201. A support member 207 is fixedly installed at one end of the support column 203. The support member 207 is fixedly connected to the mounting platform 208. In this configuration, a feeding device 400 is provided at one end of the sliding device 200. The feeding device 400 is used to place multiple lithium batteries, and the feeding direction of the feeding device 400 includes three directions, which can feed the clamps 210 in different directions.

[0049] like Figure 10 As shown, the feeding assembly further includes a telescopic cylinder 209 fixedly installed on the side of the mounting platform 208. The output end of the telescopic cylinder 209 is fixedly connected to the chuck 210. A connecting pressure plate 211 is fixedly installed on the top of the chuck 210. The negative pressure assembly includes a negative pressure pump 213. An air hole 212 is opened on one side of the chuck 210. The air hole 212 is connected to the negative pressure pump 213 through an air pipe.

[0050] In this configuration, the connecting pressure plate 211 is used to restrict the upward movement of the lithium battery, preventing the lithium battery from being not securely installed on the plastic shell base when the clamping assembly moves the plastic shell base upward to install the lithium battery. The dual function of the negative pressure assembly and the connecting pressure plate 211 ensures that the lithium battery will not easily fall off.

[0051] like Figure 14 As shown, a lifting cylinder 302 is fixedly installed on the top of the worktable 300. The output end of the lifting cylinder 302 is fixedly connected to the support plate 303. A lifting rod 301 is fixedly installed on the bottom of the support plate 303. The lifting rod 301 is movably inserted into the top of the worktable 300. A power device is also installed on the bottom of the support plate 303. In this configuration, the power device is a servo motor, which can provide precise angle control for the rotation of the sliding component. When the lifting cylinder 302 drives the support plate 303 to rise and fall, the lifting rod 301 can limit the movement of the support plate 303.

[0052] like Figure 11 , Figure 13As shown, the sliding assembly further includes a guide rail 304, one end of which is connected to the output end of the power device, and the other end is equipped with a slider 305. A slide rail 306 is slidably mounted on the bottom of the slider 305, and the slide rail 306 is fixedly connected to the support plate 303. A movable block 307 is slidably mounted on the guide rail 304, and an mounting plate 308 is fixedly mounted on the bottom of the movable block 307. A guide post 309 is fixedly mounted on the bottom of the mounting plate 308. The clamping assembly includes a support block 311 fixedly mounted on the movable block 307. An electric cylinder 312 is mounted on the output end of the support block 311, and a moving part 313 is mounted on the output end of the electric cylinder 312. A movable clamping block 315 is fixedly mounted on the top of the moving part 313. A limit rod 314 is mounted on one side of the support block 311, and the moving part 313 is movably sleeved on the limit rod 314. A fixed clamping block 316 is fixedly mounted on the top of the support block 311.

[0053] In this configuration, the slide rail 306 is annular, and the slider 305 supports one end of the guide rail 304, increasing the stability of the guide rail 304 when it moves. When the electric cylinder 312 moves, it drives the movable clamping block 315 to move through the moving part 313, so that the movable clamping block 315 clamps the plastic shell base under the action of cooperating with the fixed clamping block 316. Both the movable clamping block 315 and the fixed clamping block 316 have slots on one side to adapt to the side shape of the plastic shell base and achieve the positioning effect.

[0054] Example 3

[0055] A packaging process, implemented based on the aforementioned production equipment, involves the following steps during packaging: First, a sliding device 200 moves the loading assembly to the loading device 400. Then, a telescopic cylinder 209 is controlled to extend the clamp 210 so that it fits against the side of the lithium battery to be loaded. At this time, a negative pressure pump 213 operates and generates negative pressure through an air hole 212, allowing the clamp 210 to hold the lithium battery. The sliding device 200 then resets the loading assembly holding the lithium battery. The hydraulic cylinder 201 retracts to move the support column 203 and the mounting platform 208 upward. During the upward movement of the support column 203, the mounting platform 208 rotates through the meshing action of the toothed groove 204 and the toothed plate 205. When the rotation angle reaches 180 degrees, the hydraulic cylinder 201 stops working. At this time, the worker can weld the split connecting plate 115 to one end of the lithium battery. After welding, the hydraulic cylinder 201 operates to reset the lithium battery.

[0056] By controlling the movement of the electric cylinder 312, the movable clamping block 315 is moved, and under the action of cooperating with the fixed clamping block 316, the plastic shell base is clamped. At this time, the power device drives the guide rail 304 to rotate, and the guide rail 304 drives the movable block 307 to rotate, so that the guide post 309 rotates. The guide post 309 moves along the guide groove 310 and drives the movable block 307 to move along the guide rail 304, so that the plastic shell base is in different positions of the guide rail 304 in different directions, which makes it easy to install lithium batteries in different positions of the plastic shell base.

[0057] When the guide rail 304 rotates to the position aligned with the lithium battery on one side, the power unit stops rotating. At this time, the lifting cylinder 302 drives the support plate 303 to rise, and the plastic shell base follows suit and abuts against the bottom of the lithium battery to complete the installation. At this time, the negative pressure pump 213 stops working so that the lithium battery is disengaged from the negative pressure pump 213. After the lifting cylinder 302 resets, the power unit rotates again to continue the installation of the lithium battery.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
