Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a charging device for square lithium batteries that prevents spontaneous combustion. Background Art

[0002] Lithium batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptops use lithium-ion batteries, which are commonly known as lithium batteries. Batteries generally use materials containing lithium elements as electrodes. They are the representative of modern high-performance batteries. Lithium batteries need to be pre-charged during the production process. Some unqualified batteries are prone to spontaneous combustion during charging, so square lithium battery anti-spontaneous combustion charging devices are needed;

[0003] For example, Chinese patent CN211239383U discloses a charging device for preventing spontaneous combustion of a square lithium battery. By setting an upper cylinder body, a lower cylinder body, a sealing ring, a cylinder, a nitrogen interface and a vacuum interface, the battery is placed between the rotating shafts of the inlay groove in sequence. The nitrogen interface and the vacuum interface are respectively connected to an external nitrogen generator and a vacuum pump. The cylinder is started. Under the action of the sealing ring, the upper cylinder body and the lower cylinder body form a closed space. The vacuum pump is used to drain the air in the closed space, which can prevent the battery from spontaneous combustion when charging. After the battery is charged, the nitrogen generator is used to inject nitrogen into the closed space. Then the cylinder is started to separate the upper and lower cylinder bodies, thereby taking out the battery.

[0004] However, there are certain defects in this patent. When installing the battery block, the device needs to install the battery block in the middle position of the rotating shaft. When the battery block is fully charged, the operator needs to take out multiple batteries one by one. The process requires the operator to spend a lot of time and increases the operator's workload.

[0017] Preferably, the adjusting mechanism includes a sleeve, which is fixedly mounted on the top of the fixed plate, and a rotating handle is rotatably mounted on the side wall of the sleeve, and the other end of the rotating handle movably passes through the inner wall of the sleeve and extends to the inner wall of the sleeve, and a bevel gear 2 is installed for transmission, and a bevel gear 1 is installed on the side wall of the bevel gear 2, and a threaded rod is fixedly mounted on the top of the bevel gear 1, and the side wall of the threaded rod is rotatably connected to the inner wall of the sleeve through a bearing, and a socket block is installed on the side wall of the threaded rod, and a rectangular plate is fixedly mounted on the top of the socket block, and a long rod is fixedly mounted on the top of the rectangular plate, and an extrusion block is fixedly mounted on the other end of the long rod, and the side wall of the extrusion block is slidably connected to the inner wall of the lower cylinder body.

[0019] The utility model provides a charging device for square lithium batteries to prevent spontaneous combustion. It has the following beneficial effects:

[0031] A pulley 2 is fixedly mounted on the bottom of the fixed plate 1. There are four pulleys 2. The four pulleys 2 are of equal shape and size. The four pulleys 2 are respectively fixedly mounted at the four corners of the bottom of the fixed plate 1. The pulleys 2 facilitate the operator to move the position of the device;

[0032] A support block 3 fixedly mounted on the top of the fixed plate 1;

[0033] A lower cylinder body 5 is fixedly mounted on the top of the support block 3, an arc-shaped bracket 6 is fixedly mounted on the side wall of the lower cylinder body 5, and a top plate 7 is fixedly mounted on the other end of the arc-shaped bracket 6;

[0034] and a processing assembly 4 disposed on the side wall of the fixed plate 1;

[0035] The processing assembly 4 includes an adjustment mechanism 41 installed at the top position of the fixed plate 1, and one end of the adjustment mechanism 41 is connected to the inner wall of the lower cylinder body 5;

[0036] A charging mechanism 42 is installed at the top of the fixing plate 1 , and the charging mechanism 42 is located at the top of the adjusting mechanism 41 .

[0037] The adjusting mechanism 41 includes a sleeve 415, which is fixedly mounted on the top of the fixed plate 1, and a rotating handle 416 is rotatably mounted on the side wall of the sleeve 415, and the other end of the rotating handle 416 movably passes through the inner wall of the sleeve 415 and extends to the inner wall of the sleeve 415, and a bevel gear 2 419 is transmission-mounted, and a bevel gear 1 418 is mounted on the side wall of the bevel gear 2 419, and a threaded rod 417 is fixedly mounted on the top of the bevel gear 1 418, and the side wall of the threaded rod 417 is rotatably connected to the inner wall of the sleeve 415 through a bearing, and a socket block 414 is mounted on the side wall of the threaded rod 417, and a rectangular plate 413 is fixedly mounted on the top of the socket block 414, and a long rod 412 is fixedly mounted on the top of the rectangular plate 413, and an extrusion block 411 is fixedly mounted on the other end of the long rod 412, and the side wall of the extrusion block 411 is slidably connected to the inner wall of the lower cylinder body 5.

[0038] In this embodiment, the side wall of the bevel gear 2 419 meshes with the side wall of the bevel gear 1 418 , the side wall of the threaded rod 417 is threadedly connected to the inner wall of the socket block 414 , and the side wall of the socket block 414 is slidably connected to the inner wall of the sleeve 415 .
