Description

Battery module curing production line Technical Field

[0001] This utility model relates to the field of battery curing equipment technology, and in particular to a battery module curing production line. Background Technology

[0002] Current UV curing methods involve the UV coating line moving forward together with the UV coating process. On the production line where UV-cured batteries are coated, the batteries are placed at their placement station and then moved to the curing zone for curing. This curing operation places high demands on the production line's conveyor speed. The conveyor speed must be adapted to both the cycle time of the coating line and the battery's curing time. Different cycle times require different curing parameters, the number of curing lamps, and their layout. Too short or too long a time in the curing zone will affect the curing effect, thus limiting the flexibility of the production line's cycle time. Furthermore, since the curing zone typically uses a tunnel-like structure, if the line malfunctions and stops, the batteries remain in the curing zone, making them difficult to remove. Continuous exposure to the curing lamps can easily lead to over-curing. If the battery temperature continues to rise, the UV coating may fail, or even the electrolyte inside the battery may decompose at high temperatures, resulting in the scrapping of a batch of batteries.

[0003] Therefore, there is an urgent need for a battery module solidification production line to solve the above problems. Summary of the Invention

[0004] Based on the above, the purpose of this utility model is to provide a battery module curing production line with higher production cycle flexibility, better curing effect, and effectively improved yield.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Battery module curing production line, including:

[0007] The first sub-production line has multiple placement positions arranged along a first direction and can transport the placement positions along the first direction. The placement positions are used to place battery modules, and the first sub-production line is arranged in sequence along the first direction as a feeding section, a curing section and a unloading section.

[0008] The second sub-production line is set parallel to one side of the first sub-production line;

[0009] A lifting device is connected to the second sub-production line. The second sub-production line can transport the lifting device along the first direction. The lifting device can lift the battery module in the loading section so that the battery module is removed from the first sub-production line. After the battery module passes through the curing section, the battery module is placed on the first sub-production line in the unloading section.

[0010] The beneficial effects of this utility model are as follows:

[0011] This invention establishes a first sub-production line with multiple placement positions for battery modules along a first direction for transporting the modules. The first sub-production line includes a loading section, a curing section, and an unloading section along the first direction. The battery module curing production line also includes a lifting device connected to a second sub-production line. This lifting device can lift the battery modules in the loading section, allowing them to be removed from the first sub-production line. Simultaneously, the battery module curing production line also has a second sub-production line parallel to the first sub-production line. This second sub-production line transports the lifting device and the lifted battery modules along the first direction, allowing them to pass through the curing section and finally reach the unloading section. The lifting device can then place the battery modules back into the first sub-production line in the unloading section. In other words, the second and first sub-production lines are independent of each other. Only the speed of the second sub-production line passing through the curing section needs to be matched with the curing time. This allows for greater flexibility in setting the cycle times of the remaining sections and production lines, while also ensuring curing effectiveness and effectively improving the yield rate.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] As shown in Figures 1-6, this embodiment provides a battery module curing production line, which includes a first sub-production line 100, a second sub-production line 200, and a lifting device 300. The first sub-production line 100 can be provided with multiple placement positions along a first direction and can transport the placement positions along the first direction. The placement positions are used to place battery modules 1. The first sub-production line 100 is provided with a feeding section 101, a curing section 102, and a discharging section 103 in sequence along the first direction. The second sub-production line 200 is arranged parallel to the first sub-production line 100. The lifting device 300 is connected to the second sub-production line 200 and can transport the lifting device 300 along the first direction. The lifting device 300 can lift the battery module 1 at the feeding section 101 so that the battery module 1 is removed from the first sub-production line 100. After passing through the curing section 102, the battery module 1 is placed back into the first sub-production line 100 at the discharging section 103.

[0031] A first sub-production line 100 is set up, and the first sub-production line 100 has multiple placement positions for placing battery modules 1 along a first direction for transporting battery modules 1 along the first direction. The first sub-production line 100 is sequentially set up with a loading section 101, a curing section 102, and a unloading section 103 along the first direction. The first direction is the direction of the arrow in Figure 1. The battery module curing production line is also equipped with a lifting device 300 connected to the second sub-production line 200. The lifting device 300 can lift the battery modules 1 in the loading section 101 so that the battery modules 1 can be removed from the transport of the first sub-production line 100. Meanwhile, the battery module curing production line also has a second sub-production line 200 parallel to the first sub-production line 100. The second sub-production line 200 can transport the lifting device 300 along the first direction, so that the lifting device 300 and the battery module 1 it lifts pass through the curing section 102 and finally arrive at the unloading section 103. The lifting device 300 can then place the battery module 1 back into the first sub-production line 100 in the unloading section 103. That is, the second sub-production line 200 and the first sub-production line 100 are independent of each other. It is only necessary to ensure that the speed of the second sub-production line 200 passing through the curing section 102 is adapted to the curing time. The cycle time settings of the remaining sections and production lines are more flexible, while ensuring the curing effect and effectively improving the yield rate.

[0032] Specifically, to achieve the lifting of the battery module 1 by the lifting device 300, the lifting device 300 includes a base 310, a movable seat 320, and a lifting arm 330. The second sub-production line 200 is used to transport the base 310. The movable seat 320 is slidably disposed on the base 310 in a direction that approaches or moves away from the first sub-production line 100, and is used to drive the lifting arm 330 to approach or move away from the first sub-production line 100. The lifting arm 330 is slidably disposed on the movable seat 320 in a vertical direction. When the lifting arm 330 abuts against the bottom of the battery module 1, the vertical movement of the lifting arm 330 can realize the lifting and lowering of the battery module 1, thereby allowing the battery module 1 to detach from or be placed on the first sub-production line 100.

[0033] Furthermore, to enable the movement of the movable seat 320, the lifting device 300 also includes a horizontal drive assembly 340 disposed on the base 310. The movable seat 320 is disposed at the drive end of the horizontal drive assembly 340, which drives the movable seat 320 to move in a direction approaching or away from the first sub-production line 100. In the loading section 101, the movable seat 320 approaching the first sub-production line 100 enables the lifting arm 330 to engage with the battery module 1; in the unloading section 103, the movable seat 320 approaching the first sub-production line 100 enables the lifting arm 330 to disengage from the battery module 1 after the battery module 1 has been placed on the first sub-production line 100. Optionally, the base 310 is provided with a guide rail extending in a direction approaching or away from the first sub-production line 100, and the movable seat 320 slides with the guide rail, improving guidance and making the movement smoother. It is worth noting that each section includes multiple placement positions, which can accommodate multiple battery modules 1, allowing for simultaneous operation of multiple battery modules 1, which helps improve work efficiency.

[0034] For example, to realize the lifting device 300, a lifting drive assembly 350 is also provided on the movable seat 320. The lifting arm 330 is provided on the drive end of the lifting drive assembly 350, and the lifting drive assembly 350 is used to drive the lifting arm 330 to move in the vertical direction. The lifting drive assembly 350 drives the lifting arm 330 to rise, so that the battery module 1 is detached from the loading section 101 of the first sub-production line 100; the lifting drive assembly 350 drives the lifting arm 330 to fall, so that the battery module 1 is placed in the unloading section 103 of the first sub-production line 100, thereby realizing the independent transportation of the battery module 1 between the first sub-production line 100 and the second sub-production line 200. Optionally, the movable seat 320 is provided with a guide rail extending in the vertical direction, and the lifting arm 330 slides with the guide rail, which improves guidance and makes the movement smoother.

[0035] Preferably, to improve the reliability of supporting the battery module 1, each battery module 1 is supported by two lifting arms 330, that is, the two lifting arms 330 form a support unit 303 to support one battery module 1; further, to improve curing efficiency, the lifting device 300 is provided with two or more support units 303, which are spaced apart along the first direction, that is, the lifting drive component 350 can synchronously drive two or more support units 303 to lift and lower each time, resulting in higher efficiency and better synchronization. Optionally, the two lifting arms 330 of one support unit 303 are integrated.

[0036] As an alternative solution for the battery module solidification production line, in order to avoid the battery module 1 and the lifting device 300, the lifting arm 330 includes a crossbeam 332 and a longitudinal beam 333. The longitudinal beam 333 is connected to the drive end of the lifting drive assembly 350, and the crossbeam 332 extends toward the first sub-production line 100.

[0037] Specifically, the lifting arm 330 has an anti-detachment component 331 protruding from one end near the first sub-production line 100. The anti-detachment component 331 is used to abut against the side of the battery module 1 away from the second sub-production line 200. By setting the anti-detachment component 331, the problem of the battery module 1 tilting or even falling over in the direction away from the second sub-production line 200 when the lifting arm 330 supports the battery module 1 can be effectively avoided, thus improving the reliability of the lifting arm 330 in supporting the battery module 1. It can be understood that in the unloading section 103, the disengagement of the lifting arm 330 from the battery module 1 includes not only the disengagement of the lifting arm 330 from the bottom of the battery module 1, but also the disengagement of the anti-detachment component 331 from the side of the battery module 1.

[0038] Furthermore, a positioning groove 12 is provided at the bottom of the battery module 1. When the lifting arm 330 is placed at the bottom of the battery module 1 and lifts the battery module 1, the lifting arm 330 can be placed within the positioning groove 12. The positioning groove 12 effectively avoids problems such as misalignment and swaying of the lifting support, and effectively improves the accuracy and stability of the cooperation between the lifting arm 330 and the battery module 1. For example, the depth of the positioning groove 12 is not less than 3mm, so as to make the limiting more stable and reliable.

[0039] In this embodiment, the lifting arm 330 can rise to a preset height relative to the first sub-production line 100, with the preset height set to 5mm-30mm. If the lifting arm 330 rises too low, it will cause interference between the lifting arm 330 and the first sub-production line 100; if the lifting arm 330 rises too high, it will result in low loading and unloading efficiency in one direction, and will also occupy too much space in the height direction, increasing the overall size of the battery module curing production line.

[0040] Preferably, there are two second sub-production lines 200, which are respectively located on both sides of the first sub-production line 100. Each second sub-production line 200 is equipped with a lifting device 300. By setting up the second sub-production lines 200, when one second sub-production line 200 lifts the battery module 1 for curing, the other second sub-production line 200 can independently perform the operation of picking up and placing the battery module 1. That is, the lifting devices 300 on different second sub-production lines 200 can be used to lift or lower the battery module 1 respectively, so as to realize the alternating operation of the battery module 1, reduce the waiting time required for resetting only one second sub-production line 200, and thus improve the curing efficiency.

[0041] In this embodiment, the battery module 1 includes a battery to be cured and a tray 11. The battery to be cured is placed on the tray 11, and the lifting device 300 is used to lift the tray 11. The positioning groove 12 is provided at the bottom of the tray 11, and the anti-detachment component 331 abuts against the side of the tray 11 away from the second sub-production line 200.

[0042] To achieve positioning of the tray 11, a positioning pin 110 is provided at the placement position. The positioning pin 110 can at least partially pass through the tray 11, which not only positions the tray 11 but also improves the stability of the tray 11 when the first sub-production line 100 moves, preventing the tray 11 and the battery to be cured from falling off. The positioning pin 110 extends vertically to avoid interference with the lifting device 300 lifting the tray 11. Correspondingly, the bottom of the tray 11 is also provided with a positioning groove or positioning through hole that mates with the positioning pin 110. To improve the reliability of the connection between the battery to be cured and the tray 11, the tray 11 can be configured to magnetically connect with the battery to be cured, resulting in a more reliable connection without damaging the battery.

[0043] Furthermore, the battery module curing production line also includes a curing device 400, which includes a curing lamp. The curing lamp is located in the curing section 102 and is angled to the horizontal plane to improve the coverage of the top and sides of the battery to be cured, thereby ensuring the curing effect. Preferably, the curing device 400 also includes an adjustment component for adjusting the angle between the curing lamp and the horizontal plane to adapt to different curing scenarios and improve the versatility of the battery module curing production line.

[0044] For example, the curing device 400 also includes a mounting plate on which the curing lamp is disposed. One end of the mounting plate is rotatably disposed relative to the first sub-production line 100. The adjustment assembly includes an adjustment cylinder disposed at the other end of the mounting plate. The tilt angle of the mounting plate is adjusted by adjusting the extension and retraction of the cylinder, thereby adjusting the angle between the curing lamp and the horizontal plane.

[0045] The working process of the above-mentioned battery module curing production line is as follows: The coated batteries to be cured are placed on tray 11 and transported via the first sub-production line 100 to the loading section 101, where they stop. Then, the horizontal drive component 340 of the lifting device 300 drives the movable seat 320 closer to the first sub-production line 100, placing the lifting arm 330 below the tray 11. Next, the lifting drive component 350 drives the lifting arm 330 to rise vertically, detaching at least two battery modules 1 from the first sub-production line 100. The second sub-production line 200 drives the lifting device 300 and the battery modules 1 to the curing section 102 for curing. At this time, the first sub-production line 100 and the second sub-production line 200 can move relatively independently. After curing, the battery module 1 enters the unloading section 103. The lifting drive component 350 drives the lifting arm 330 to descend vertically, placing at least two battery modules 1 back into the first sub-production line 100. Next, the horizontal drive component 340 drives the movable seat 320 away from the first sub-production line 100, so that the lifting arm 330 is away from below the tray 11. While the second sub-production line 200 is performing the above actions, another second sub-production line 200 can simultaneously complete the lifting of other battery modules 1 to be cured. When the second sub-production line 200 that has completed curing resets in the first direction, the battery modules 1 on the other second sub-production line 200 can directly enter the curing section 102 for curing, which is more efficient. In addition, it is worth noting that, based on the different production cycle designs of the battery module curing production line, when the lifting device 300 of one sub-production line has not completed its reset, the lifting device 300 of the other sub-production line can simultaneously enter the curing section 102 for curing, without having to wait for one lifting device 300 to be fully reset before the other lifting device 300 can be cured, thereby reducing waiting time and further improving efficiency.

[0046] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
