Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery production technology, specifically a vacuum integrated system for lithium battery production. Background Technology
[0002] Lithium-ion batteries are characterized by high nominal voltage, high specific energy, long cycle life, and no memory effect. They are also environmentally friendly and pollution-free, making them widely used in digital products such as mobile phones and laptops, as well as various portable devices. The moisture content in lithium-ion batteries has a significant impact on their performance. When the moisture content in the battery electrodes exceeds the standard, it can undergo side reactions with the electrolyte, causing damage to the battery. This can result in lower battery capacity, battery expansion and explosion, lower internal resistance, larger size, and reduced cycle performance. Therefore, controlling the moisture content in batteries is a crucial factor in battery manufacturing.

The motor is fixedly mounted at the center of the bottom of the chamber via a bracket. The output shaft of the motor is fixedly sleeved onto the fixed shaft, and the top of the fixed shaft penetrates the bottom of the chamber and extends into the interior of the chamber. This invention effectively solves the problems of uneven heat distribution inside existing vacuum ovens for lithium battery production, leading to reduced drying efficiency, and the inability to quickly lower the internal temperature of the oven after drying, thus affecting work efficiency.
[0004] In the aforementioned patent, although the device can place lithium batteries in an oven for baking, after the lithium batteries are dried, the oven door needs to be opened, the dried lithium batteries need to be removed, and new lithium batteries need to be placed in, which increases the cumbersomeness of the operation and reduces the work efficiency. Therefore, this utility model provides a vacuum integrated system for lithium battery production. Utility Model Content

[0012] Beneficial effects
[0013] This invention provides a vacuum integrated system specifically for lithium battery production. Compared with existing technologies, it has the following advantages:
[0014] (1) The dedicated vacuum integrated system for lithium battery production uses a U-shaped frame to move the lithium batteries on the placement rack in one of the rotating components into the box, while the placement rack in the other rotating component moves to the outside of the box. After the lithium batteries are moved into the box, multiple heating rods inside the box start to work to heat and dry the lithium batteries.

[0015] (2) The dedicated vacuum integrated system for lithium battery production is started by the second motor, which drives the placement rack to rotate. The lithium batteries placed on the multiple placement plates on the inner wall of the placement rack rotate accordingly, so that the lithium batteries can be heated and dried evenly. In order to ensure the drying effect, the vacuum pump at the top of the box is started to draw the inside of the box into a vacuum state, reducing the influence of air on the drying process.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides two technical solutions:
[0023] Figures 1-4 The first embodiment is shown: a vacuum integrated system for lithium battery production, including a base 1, a guide groove 11 extending through the top of the base 1, and a drying mechanism for drying lithium batteries, the drying mechanism including: a heating component 2, disposed on the top of the base 1, the heating component 2 including a housing 21 fixedly installed on the top of the base 1, with openings 23 on both the left and right sides of the housing 21; a moving component 3, disposed inside the heating component 2, the moving component 3 including a moving seat 33 movably disposed inside the guide groove 11, a U-shaped frame 31 fixedly installed on the top of the moving seat 33, the U-shaped frame 31 contacting the top surface of the base 1, a partition 32 fixedly connected to the inner bottom of the U-shaped frame 31 near the middle, and the partition 32 dividing the inner side of the U-shaped frame 31 into two parts; and a rotating component 4, disposed inside the moving component 3, with multiple heating rods 22 installed on the front and rear inner walls of the housing 21, and openings 23. The surface of the moving assembly 3 is in contact with the sides of the U-shaped frame 31 and the partition 32. The moving assembly 3 also includes a first motor 34 and a guide rod 36. The first motor 34 is fixedly installed on the right side of the base 1. The output end of the first motor 34 moves through the left side of the base 1 and extends into the interior. A lead screw 35 is fixedly installed on the output end of the first motor 34. The lead screw 35 is threaded through the moving seat 33. The left end of the lead screw 35 is rotatably set on the inner wall of the base 1. The guide rod 36 slides through the moving seat 33, and the two ends of the guide rod 36 are respectively fixed on the inner walls of the two sides of the base 1. By placing the lithium battery to be dried on the placement plate 42 of the placement rack 41, the first motor 34 is started, which drives the lead screw 35 to rotate, so that the moving seat 33 moves along the guide rod 36 in the guide groove 11, moving the U-shaped frame 31 and the internal placement rack 41 and lithium battery into the box 21. The openings 23 on both sides of the box 21 are in contact with the sides of the U-shaped frame 31 and the partition 32, forming a relatively closed space.
[0024] Figures 1-4The second embodiment is shown, and its main difference from the first embodiment is that the rotating assembly 4 includes two second motors 44 equidistantly mounted on the bottom of the movable base 33. The output ends of both second motors 44 movably penetrate the bottom of the movable base 33 and extend upward. Placement racks 41 are mounted on the output ends of the second motors 44. The two placement racks 41 are symmetrically arranged on the left and right sides of the inner side of the U-shaped frame 31. Multiple placement plates 42 are fixedly connected to the inner wall of the placement racks 41. Limiting holes 43 are provided at the bottom of both placement racks 41. Two cylinders 5 are fixedly mounted on the bottom of the movable base 33. The telescopic ends of the cylinders 5 slide sequentially through the bottom of the movable base 33 and the U-shaped frame 31 and extend upward. Limiting devices that cooperate with the limiting holes 43 are installed on the telescopic ends of the cylinders 5. A vacuum pump 6 is installed on the top of the housing 21 and column 51. The input end of the vacuum pump 6 passes through the top of the housing 21 and extends to the inside. The heating rod 22 is activated to heat and dry the lithium battery. At the same time, the second motor 44 is activated to drive the placement rack 41 to rotate, so that the lithium battery is heated evenly. To ensure the drying effect, the vacuum pump 6 is activated to evacuate the inside of the housing 21 into a vacuum state. When the placement rack 41 moves with the U-shaped frame 31, the second motor 44 stops and the cylinder 5 is activated. The extension end of the cylinder 5 drives the limiting column 51 to move upward and insert it into the limiting hole 43 at the bottom of the placement rack 41, thereby fixing the placement rack 41. This ensures that the placement rack 41 stays at the correct angle and prevents the placement rack 41 from rotating during movement.
[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0026] During operation, firstly, the first motor 34 is started. The output end of the first motor 34 drives the lead screw 35 to rotate. Since the lead screw 35 is threaded through the movable seat 33 and the movable seat 33 is restricted by the guide rod 36 to move only in the direction of the guide rod 36, the movable seat 33 moves within the guide groove 11 of the base 1. The U-shaped frame 31 on top of the movable seat 33 and the internal partition 32 move accordingly. The U-shaped frame 31 carries the lithium batteries on the placement rack 41 in one of the rotating components 4 into the housing 21, while the placement rack 41 in the other rotating component 4 moves to the outside of the housing 21. After the lithium batteries move into the housing 21, the multiple heating rods 22 inside the housing 21 start working to heat and dry the lithium batteries. During the drying process, the operator uses this time difference to place a new batch on the placement plate 42 in the outer placement rack 41. The process of drying lithium batteries is achieved by removing either the lithium batteries that are to be dried or the lithium batteries that have already been dried, thereby greatly improving work efficiency. During the drying process, the second motor 44 is started, which drives the placement rack 41 to rotate. The lithium batteries placed on the multiple placement plates 42 on the inner wall of the placement rack 41 rotate accordingly, so that the lithium batteries can be heated and dried evenly. In order to ensure the drying effect, the vacuum pump 6 at the top of the box 21 is started to create a vacuum inside the box 21, reducing the influence of air on the drying process. When the placement rack 41 moves with the U-shaped frame 31, the second motor 44 stops and the cylinder 5 is started. The extension end of the cylinder 5 drives the limiting post 51 to move upward, so that it is inserted into the limiting hole 43 at the bottom of the placement rack 41, thereby fixing the placement rack 41. This ensures that the placement rack 41 stays at the correct angle and prevents the placement rack 41 from rotating during the movement.
