Description

Technical Field

[0001] This application relates to the field of battery production technology, and in particular to a battery baking apparatus. Background Technology

[0002] With the increasing application of batteries in all aspects of people's lives, battery safety is becoming an important factor in battery performance. Current battery technology requires strict control over the internal moisture content during production. This is because rechargeable batteries generate heat during use; if moisture is present inside, prolonged heating will cause the moisture to evaporate and expand dramatically, leading to the battery bulging outwards.

[0003] In severe cases, the battery may explode. Moreover, moisture has a significant impact on the performance of secondary batteries, including indicators such as voltage, internal resistance, and self-discharge. Excessive moisture content can lead to product scrap, quality degradation, and even the safety hazard of explosion. Therefore, vacuum baking is required in multiple production processes of secondary batteries to remove moisture as much as possible and minimize harm.

[0004] In related technologies, semi-finished batteries undergo moisture content testing before baking, and the moisture content of these batteries typically varies before baking. However, current baking equipment does not differentiate between batteries with different moisture contents during the manufacturing process. Batteries with abnormal moisture content are not subject to dedicated baking control (i.e., batteries with different moisture contents are placed in the same baking oven for baking), which can easily lead to the failure of moisture content control after baking, ultimately resulting in battery scrap and significantly increasing the cost of battery cell manufacturing. Summary of the Invention

[0005] This application provides a battery baking device to solve the problems in related technologies that do not differentiate between batteries to be baked during the manufacturing process based on their moisture content and have low working efficiency.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] This application provides a battery baking device that solves the problems in related technologies where batteries to be baked during the manufacturing process are not differentiated based on their moisture content, and where the working efficiency is low.

[0029] See Figure 1 As shown, this application embodiment provides a battery baking apparatus, including:

[0030] The battery sorting module includes a conveyor line 11, on which a sensor 12 for identifying battery information is installed. Each battery 1 has a label indicating its information. The water content of the battery 1 can be determined by identifying the label information through the sensor 12. A battery tray 2 is provided on one side of the conveyor line 11. The battery tray 2 is used to classify and place batteries 1 with different water contents, and a first handling mechanism 13 is provided to classify and place the batteries 1 on each battery tray 2.

[0031] All batteries 1 entering the conveyor line 11 undergo moisture detection and are labeled. The sensing device 12 automatically identifies the batteries based on the labels, thus the water content information of each battery is available. The label can represent the water content information of each battery 1. For example, the label can be set with different colors, patterns, or shapes according to the different water contents of the batteries, or different QR codes can be set according to the different water contents of the batteries. The sensing device 12 can obtain the water content information of the battery 1 by recognizing the label or QR code.

[0032] A battery baking module includes at least two baking ovens 21 for sorting and placing battery trays 2 and drying batteries. One of the baking ovens 21 must be used independently to bake batteries 1 with abnormal moisture content. Batteries 1 with abnormal moisture content and batteries 1 with normal moisture content are baked independently in different baking ovens 21 at set times, pressures, and temperatures to improve production efficiency and product quality. A second conveying mechanism 22 is provided between the baking ovens 21 and the battery trays 2 to sort and place the battery trays 2 into the respective baking ovens 21.

[0033] The battery baking apparatus of this application embodiment includes a sensing device 12 for automatically identifying information of the batteries 1 delivered by the conveyor line 11. The sensing device 12 obtains the water content of each battery 1 based on the identification information and sends the information to the first conveying mechanism 13. The first conveying mechanism 13 automatically sorts batteries 1 with different water content ranges from the conveyor line 11 onto each battery tray 2 to complete the automatic sorting and classification operation.

[0034] Those skilled in the art can set specific water content thresholds for batteries according to actual needs. Batteries with water content within a certain threshold range are defined as batteries with normal water content, while batteries with water content exceeding the upper limit of the threshold are defined as batteries with excessive water content. For example, in actual production, only the upper limit of the water content threshold is set to ≤650ppm. Batteries below this threshold are considered qualified, while batteries exceeding the threshold are considered unqualified.

[0035] The batteries to be baked are classified into two types based on their respective water content. Each type of battery is identified by a different identifier to indicate its water content. At least two baking ovens 21 are also provided for baking each of the two types of batteries. These ovens independently bake each type of battery at a set time, pressure, and temperature (the baking parameters for batteries with abnormal water content are specifically set by those skilled in the art according to actual needs). For batteries exceeding the water content threshold, the baking oven 21 and baking process can be specified separately according to the water content gradient; these do not affect each other and can be configured as needed.

[0036] The battery baking module uses the second conveying mechanism 22 to classify and place the batteries 1 on each battery tray 2 into each baking oven 21. Each baking oven 21 has a set time, pressure and temperature, so that batteries 1 with different moisture content ranges are baked and dehumidified individually, thereby improving the production efficiency of batteries 1 and improving the production quality of batteries 1.

[0037] In some alternative implementations: see Figure 1 and Figure 2 As shown in the figure, the application embodiment provides a battery baking device, which further includes a tray support 14 supporting the battery tray 2. The tray support 14 is provided with at least two sets of battery trays 2 stacked on each other, and the tray support 14 is provided with positioning platforms 16 for placing each battery tray 2, and each positioning platform 16 is provided with a lifting mechanism 17 for lifting the battery tray 2 upward.

[0038] In this embodiment, the tray support 14 is provided with positioning platforms 16 for placing each battery tray 2, and a lifting mechanism 17 for lifting each positioning platform 16 and the battery tray 2 on the positioning platform 16. The lifting mechanism 17 can move freely up and down. When the second conveying mechanism 22 moves the top battery tray 2 into the baking oven 21, the lifting mechanism 17 lifts the remaining battery tray 2 upwards to a set height.

[0039] In some alternative implementations: see Figure 1 and Figure 2 As shown in the figure, the application embodiment provides a battery baking device. The tray support 14 of the device has a rectangular frame structure. Inside the tray support 14, there is a receiving space for storing battery trays 2. The receiving space can hold multiple stacked battery trays 2 side by side. The top of the tray support 14 has a top opening for taking out and putting in battery trays 2.

[0040] The lifting mechanism 17 includes multiple vertical linear modules respectively fixed on the pallet support 14. The sliding blocks of the vertical linear modules reciprocate up and down along the height direction of the pallet support 14. The multiple vertical linear modules are arranged vertically, and the sliding blocks of each vertical linear module are fixedly connected to the positioning platform 16. Each vertical linear module moves up and down synchronously, thereby driving the positioning platform 16 to move up and down smoothly.

[0041] In some alternative implementations: see Figure 1 and Figure 2 As shown in the figure, the application embodiment provides a battery baking device. The top of the tray support 14 of the device is provided with a position sensor (not shown in the figure) for detecting the position and height of the top battery tray 2. The position sensor is electrically connected to the lifting mechanism 17. When the lifting mechanism 17 drives the top battery tray 2 upward to a set height, the position sensor controls the lifting mechanism 17 to stop moving upward.

[0042] The top of the positioning platform 16 is provided with multiple guide pins and positioning blocks, and the bottom of the battery tray 2 is provided with guide holes that match the guide pins and positioning grooves that match the positioning blocks. The guide pins and positioning blocks are used to achieve precise positioning of the battery tray 2 placed on the positioning platform 16, so as to prevent the position of the battery tray 2 placed on the positioning platform 16 from changing and affecting the subsequent handling of the battery 1 by the first handling mechanism 13 and the battery tray 2 by the second handling mechanism 22.

[0043] In some alternative implementations: see Figure 1 and Figure 2As shown in the illustration, the application embodiment provides a battery baking device. The top of the tray support 14 of the device is provided with multiple cameras 19 for detecting the number of batteries 1 on each top battery tray 2. A controller is connected between the cameras 19 and the second conveying mechanism 22. When the camera 19 detects that the top battery tray 2 is full of batteries 1, it sends a control signal to the controller, thereby controlling the second conveying mechanism 22 to place the top battery tray 2 into the baking oven 21.

[0044] Two sets of pallet supports 14 are provided. Each set of pallet supports 14 has a sliding rail 15 at its bottom, and a guide pulley 18 that rolls along the sliding rail 15 at its bottom. A drive module drives the pallet supports 14 to move along the sliding rail 15. The two sets of pallet supports 14 work alternately. When one set of pallet supports 14 is stacking batteries 1, the other set of pallet supports 14 is stacking battery pallets 2, thereby improving the efficiency of battery 1 sorting and increasing the work cycle.

[0045] In some alternative implementations: see Figure 1 and Figure 2 As shown in the illustration, an embodiment of the application provides a battery baking device. The sensing device 12 of the device includes a barcode reader or color mark sensor for reading the identification information on the battery 1, and a controller connected to the barcode reader or color mark sensor. A first conveying mechanism 13 is connected to the controller. When the barcode reader reads that the moisture content in the identification information on the battery 1 is abnormal, the controller controls the first conveying mechanism 13 to place the battery 1 on the battery tray 2 with abnormal moisture content.

[0046] In some alternative implementations: see Figure 1 and Figure 2 As shown in the illustration, the application embodiment provides a battery baking device. The first transport mechanism 13 and the second transport mechanism 22 of this device are both industrial robots, each equipped with a gripper for picking up or releasing the battery 1. The baking ovens 21 are arranged side-by-side. A horizontal linear module 23 is provided on the front of each baking oven 21, driving the second transport mechanism 22 to reciprocate sequentially on the front of each baking oven 21. The length of the horizontal linear module 23 is greater than the sum of the lengths of all baking ovens 21, thereby increasing the working area of ​​the second transport mechanism 22.

[0047] Working principle

[0048] This application provides a battery baking device. The battery baking device of this application is equipped with a battery sorting module, which includes a conveyor line 11, a sensing device 12 for identifying battery information on the conveyor line 11, a battery tray 2 on one side of the conveyor line 11, and a first conveying mechanism 13 for classifying and placing batteries 1 on each battery tray 2; the battery baking module includes at least two baking ovens 21 for classifying and placing battery trays 2 and drying batteries 1, and a second conveying mechanism 22 for classifying and placing battery trays 2 in each baking oven 21 is provided between the baking ovens 21 and the battery trays 2.

[0049] Therefore, the battery baking apparatus of this application is equipped with a sensor device 12 that automatically identifies the information of the batteries 1 delivered by the conveyor line 11. The sensor device 12 obtains the moisture content of each battery 1 based on the identification information and sends the information to the first conveying mechanism 13. The first conveying mechanism 13 automatically sorts the batteries 1 with different moisture content ranges from the conveyor line 11 onto each battery tray 2 to complete the automatic sorting and classification operation. The battery baking module uses a second conveying mechanism 22 to classify and place the batteries 1 on each battery tray 2 into each baking oven 21. Each baking oven 21 bakes and dehumidifies the batteries 1 with different moisture content ranges separately, thereby improving the production efficiency of the batteries 1 and improving the product quality of the batteries 1.
