Description

Technical Field

[0001] This invention generally relates to the field of lithium battery technology. More specifically, this invention relates to a lithium battery baking production line. Background Technology

[0002] In recent years, the lithium battery industry has developed rapidly, and the production process of lithium batteries is also changing towards diversification in terms of variety and small batches in order to meet the ever-changing consumer market. Traditional lithium battery production urgently needs to be improved in many aspects such as efficiency and technological advancement.

[0003] Traditional baking production lines often require the use of forks to pick up and move the lithium battery fixtures into or out of the baking chamber. This process takes up a lot of space and involves a lot of wasted motion during the process of picking up the fixtures and moving them into or out of the baking chamber. This does not meet the requirements of lean manufacturing and cannot adequately meet the capacity requirements of upstream and downstream processes. The baking process in lithium battery production has become a bottleneck in capacity.

[0004] In addition, after the lithium batteries are baked in the baking chamber, nitrogen is often added to the baking chamber for pressurization and initial cooling. Then the fixture holding the lithium batteries is removed and moved to the cooling chamber for final cooling. However, during the process of removing the lithium battery fixture from the baking chamber, the ambient temperature in the workshop is much lower than the temperature of the lithium battery fixture. Therefore, the lithium batteries that have already undergone the baking process are very likely to absorb moisture from the workshop environment again, affecting the baking effect of the lithium batteries. At the same time, when the baking chamber is opened, nitrogen is directly released into the working environment of the production workshop. The lack of a dedicated exhaust pipe causes nitrogen to leak into the working environment.

[0005] In view of this, there is an urgent need to provide a lithium battery baking production line to solve the above problems. Summary of the Invention

[0006] To address at least one or more of the technical problems mentioned in the background section, this invention proposes a lithium battery baking production line.

[0007] Therefore, the present invention provides the following technical solution.

[0008] This invention discloses a lithium battery baking production line, comprising:

[0009] The track is fixedly laid on the workshop floor;

[0010] The baking module includes multiple baking chambers for baking lithium batteries to remove moisture from them. The baking chambers are arranged in two rows and are respectively located on both sides of the track. The side of each baking chamber used for the lithium battery to enter or exit faces the track.

[0011] A cooling module includes at least one set of cooling chambers for cooling lithium batteries removed from the baking chamber, wherein the cooling chambers are positioned so that the side of the lithium batteries entering or exiting faces the track.

[0012] A transport module, which can travel along the track, is used to transport lithium batteries and move them into the baking oven or the cooling oven, or to remove lithium batteries from the baking oven or the cooling oven.

[0013] The feeding module is used to store the lithium batteries to be baked, so that the lithium batteries can be moved to the handling module;

[0014] The unloading module is used to receive lithium batteries that have been baked and / or cooled;

[0015] A sealing module is used to form a closed, independent space to isolate it from the workshop environment. When the transport module transfers the lithium battery between the baking module and the cooling module, the lithium battery is in the closed, independent space, and the pressure in the closed, independent space is greater than the pressure of the workshop environment. The sealing module is provided with sealing doors at the positions of the loading module and the unloading module.

[0016] Preferably, it also includes a temporary storage module for temporarily storing the baked and / or cooled lithium batteries, wherein the lithium battery storage location of the temporary storage module is located within the sealed independent space.

[0017] Preferably, both the baking chamber and the cooling chamber have sliding doors on the side for the lithium battery to enter and exit.

[0018] Preferably, the sealing module includes a cover, and the orthographic projection of the sliding door of the baking chamber and the cooling chamber onto the workshop floor is located within the range of the orthographic projection of the cover onto the workshop floor, such that the cover allows the sliding door to be located within the sealed independent space.

[0019] Preferably, the transport module includes a car capable of moving along a first preset trajectory on the track. The car is equipped with a lifting platform capable of moving up and down. A telescopic platform is provided above the lifting platform. Openings are provided on the left and right sides of the car. The telescopic platform can move horizontally along a second preset trajectory within a preset range to different sides of the track through the openings. The telescopic platform also includes a gripper for moving the lithium battery clamp from the telescopic platform into the baking oven or the cooling oven, or for moving the lithium battery clamp from the baking oven or the cooling oven to the telescopic platform.

[0020] Preferably, the gripper is a hook-type gripper.

[0021] Preferably, there are two hook-type grippers, which are symmetrically arranged at the first and second ends of the telescopic platform and are used to alternately hook from both sides of the lithium battery clamp to move the lithium battery clamp out or in.

[0022] Preferably, the two hook-type grippers can move horizontally relative to the telescopic platform within a first preset stroke, and can move vertically relative to the telescopic platform within a second preset stroke.

[0023] Preferably, the track has multiple preset positions, which are located directly in front of each baking oven or cooling oven. The car is used to travel along the first preset trajectory on the track and reach the preset position. An adjustment plate is provided below the telescopic platform, and a rotary bearing is provided between the adjustment plate and the lifting platform. The car also includes a drive cylinder, the telescopic end of which is hinged to the adjustment plate, and the fixed end of which is hinged to the telescopic platform.

[0024] Preferably, a plurality of support parts for supporting the adjustment plate are provided between the adjustment plate and the lifting platform.

[0025] Preferably, the support includes multiple sets of fixed supports disposed on the upper surface of the lifting platform, each fixed support being provided with a bearing, the bearing being used to contact the bottom of the adjusting plate and support the adjusting plate to rotate relative to the lifting platform.

[0026] Preferredly, each fixed support is evenly arranged on a predetermined circumference centered on the slewing bearing.

[0027] The technical solution provided in this application may include the following beneficial effects:

[0028] By utilizing the apparatus described above and in several embodiments of the present invention, namely, by arranging baking and cooling chambers on both sides of a track and installing a transport module that can move along the track, while simultaneously constructing a sealed, independent space under positive pressure, the different functional chambers arranged on both sides of the track are placed within this sealed, independent space. This solves the problem of the impact of uncontrollable factors caused by human operation on the baking effect, prevents the lithium batteries from reabsorbing moisture from the workshop environment after baking or cooling, thus avoiding damage to the lithium batteries, effectively ensuring the achievement of the purpose of baking and dehydration, and improving the automation level of the production line and the baking effect of the lithium batteries. At the same time, using the technical solution of the present invention, the nitrogen gas already filled into the baking chamber is directly discharged into the casing when the sliding door is opened, instead of directly leaking into the natural environment of the workshop, ensuring the safety of the production workshop.

[0029] This invention not only solves the aforementioned defects, but also moves the lithium battery clamps in and out by installing a telescopic platform inside the car that travels along the track, and using two hook-type grippers at both ends of the telescopic platform to alternately hook and pull the clamps as the sliding door of the baking chamber opens. The space required for moving the clamps in and out using the hook-type grippers is extremely small, effectively solving the problem of the large operating space required for the large range of motion of a six-axis robot's fork arm in grasping the clamps. This significantly improves the utilization rate of the workshop space, and the space saved allows for the arrangement of more baking chambers, helping to further increase the production capacity of the lithium battery baking process. In addition, this invention is inexpensive. Compared to the construction investment required for equipping robots and complex robotic arms, this invention saves on the construction cost of the baking production line and further solves the problem of wasted motion in existing technologies using six-axis robot fork arms to grasp clamps.

[0036] Embodiments will now be described with reference to the accompanying drawings. It should be understood that, for the sake of simplicity and clarity, reference numerals may be repeated in the drawings to indicate corresponding or similar elements where deemed appropriate. Furthermore, numerous specific details are set forth in this invention to provide a thorough understanding of the embodiments described herein. However, those skilled in the art will understand that the embodiments described herein can be practiced without these specific details. In other instances, well-known methods, processes, and components have not been described in detail so as not to obscure the embodiments described herein. Moreover, this description should not be construed as limiting the scope of the embodiments described herein.

[0037] According to one embodiment of the present invention, a lithium battery baking production line is provided, comprising:

[0038] Track 11 is fixedly laid on the workshop floor;

[0039] The baking module includes multiple baking chambers 12, which are used to bake lithium batteries to remove moisture from the lithium batteries. Each baking chamber 12 is arranged in two rows and is respectively located on both sides of the track 11. The side of each baking chamber 12 used for the lithium battery to enter and exit faces the track 11.

[0040] The cooling module includes at least one set of cooling boxes 13, which are used to cool lithium batteries removed from the baking box 12. The side of the cooling box 13 where the lithium batteries enter and exit is positioned facing the track 11.

[0041] The transport module 14 can travel along the track 11. It is used to transport lithium batteries and move them into the baking chamber 12 or the cooling chamber 13, or to remove lithium batteries from the baking chamber 12 or the cooling chamber 13.

[0042] The feeding module is used to store the lithium batteries to be baked, so that the lithium batteries can be moved to the handling module 14;

[0043] The unloading module is used to receive lithium batteries that have been baked and / or cooled;

[0044] The sealing module is used to form a closed and independent space to isolate it from the workshop environment. When the handling module 14 transfers the lithium battery between the baking module and the cooling module, the lithium battery is in a closed and independent space, and the pressure in the closed and independent space is greater than the pressure of the workshop environment. The sealing module is equipped with sealing doors at the positions of the loading module and the unloading module.

[0045] Before opening the baking chamber 12 after the lithium battery baking is complete, nitrogen gas must be introduced to adjust the pressure inside the baking chamber 12 to be approximately the same as the environmental pressure in the production workshop, making it easier to open the baking chamber 12. Without a sealed independent space, nitrogen gas is directly discharged into the workshop environment, while with a sealed independent space, nitrogen gas is discharged into that sealed independent space.

[0046] The pressure inside the sealed independent space mentioned in the above embodiments is greater than the pressure of the workshop environment. This can be addressed by installing a high-efficiency fan filter unit on the top of the sealing module to fill the housing 41 of the sealing module with clean and dry air. This pressurizes the housing 41 of the sealing module and maintains its internal pressure above the atmospheric pressure of the workshop environment. At the same time, an exhaust pipe connected to the sealed independent space is installed so that the nitrogen in the sealed independent space is replaced by continuously input clean and dry air and discharged to the outside, preventing nitrogen from directly entering the production workshop.

[0047] In one embodiment, considering the possibility that the loading and unloading modules cannot keep up with the production capacity, a temporary storage module 21 is also provided. The temporary storage module 21 is used to temporarily store the baked and / or cooled lithium batteries. The lithium batteries in the temporary storage module 21 are stored in a sealed, independent space. This is to prevent the baked lithium batteries from absorbing moisture from the air in the workshop environment after being transported there by the unloading module, thus protecting them from damage. Therefore, the temporary storage module 21 in this sealed, independent space provides protection for the baked lithium batteries.

[0048] In the aforementioned embodiments, both the baking chamber 12 and the cooling chamber 13, used for the entry and exit of lithium batteries, are equipped with sliding doors. Compared to hinged doors, sliding doors require minimal surrounding space during opening and closing, meaning they can be opened and closed within a limited space. This helps to improve the compactness of the production line layout and increase the utilization rate of the production workshop space.

[0049] In one embodiment, the sealing module includes a cover 41, and the orthographic projection of the sliding door of the baking chamber 12 and cooling chamber 13 onto the workshop floor is located within the orthographic projection of the cover 41 onto the workshop floor, limited to the cover 41 allowing the sliding door to be located within a sealed, independent space. For example, the edge of the cover 41 can be fixed to the edge around the door frame of the sliding door of the baking chamber 12, and a sealing strip or sealant can be used to seal the joint between the cover 41 and the baking chamber 12. This arrangement can save on the amount of material required to manufacture the cover 41, i.e., it is not necessary to include all the baking chamber 12, cooling chamber 13, loading module, unloading module, etc., within the sealed, independent space; only the area around the side of the baking chamber 12 and cooling chamber 13 used for lithium battery entry and exit needs to be included within the sealed, independent space.

[0050] In one embodiment, the structure of the transport module 14 may include a car 51 that can travel along a first preset trajectory on the track 11, a lifting platform 52 that can move up and down inside the car 51, a telescopic platform 53 above the lifting platform 52, openings on the left and right sides of the car 51, and the telescopic platform 53 that can move horizontally along a second preset trajectory within a preset range to different sides of the track 11 through the openings. The telescopic platform 53 also includes a gripper 54, which is used to move the lithium battery clamp from the telescopic platform 53 into the baking oven 12 or the cooling oven 13, or to move the lithium battery clamp from the baking oven 12 or the cooling oven 13 onto the telescopic platform 53.

[0051] The lifting platform 52 can be raised and lowered relative to the car 51 by a sprocket and chain drive structure. The openings on the left and right sides of the car 51 refer to the openings on both sides of the car 51 facing the baking box 12 and the cooling box 13 located on both sides of the track 11.

[0052] When the lifting platform 52 inside the car 51 stops at a preset height, the gripper 54 picks up the lithium battery clamp and moves it into or out of the baking chamber 12. It is understood that this preset height is such that the height of the upper surface of the lifting platform 52 is consistent with the height of the bottom surface of one of the baking chambers in the baking chamber 12. Of course, this preset height varies depending on the position of the bottom surface of the baking chamber or cooling chamber for each pick-up or drop of the lithium battery clamp.

[0053] In one embodiment, the gripper 54 may be a hook-type gripper 54. Specifically, there are two hook-type grippers 54, which are symmetrically arranged at the first and second ends of the telescopic platform 53 and are used to alternately hook from both sides of the lithium battery clamp to move the lithium battery clamp out or in.

[0054] The claw gripper 54 may have multiple downward-facing hook slots. The hook slots are designed to engage with the lithium battery clamp. The hook slots are used to hook the edge of the lithium battery clamp to pick up the lithium battery clamp. Alternatively, protrusions may be provided on both sides of the lithium battery clamp so that the lithium battery clamp can be picked up when any of the hook slots of the gripper 54 moves to the protrusion.

[0055] In the above embodiment, the two hook-type grippers 54 can move horizontally relative to the telescopic platform 53 within a first preset stroke, and can move vertically relative to the telescopic platform 53 within a second preset stroke, so that the relative positions of the grippers 54 with the telescopic platform 53 in the vertical and horizontal directions can be adjusted.

[0056] Taking the removal of the lithium battery clamp from the baking oven 12 as an example, the process of the two grippers 54 hooking the lithium battery clamp in an alternating manner is as follows: Initially, the proximal hooks of the two grippers 54 can simultaneously hook the lithium battery clamp. When the horizontal movement of the two grippers 54 relative to the telescopic platform 53 reaches its limit within the first preset stroke, it can be understood that at least part of the lithium battery clamp has entered the telescopic platform 53. The first gripper 54 is kept in place with its proximal hook hooked on the lithium battery clamp and stationary relative to it to prevent the clamp from shaking. The second gripper 54 is then raised vertically within the second preset stroke, and after horizontal adjustment within the first preset stroke, it is lowered again vertically within the second preset stroke. For example, it can be lowered to its original height before being raised. The first gripper 54 is ready to hook the lithium battery clamp again, provided that the distal hook groove can hook the lithium battery clamp. At the same time, the first gripper 54 is raised or lifted vertically within the second preset stroke range to remove the obstruction to the hooking action of the second gripper 54. However, the second gripper 54 still needs to remain stationary. Meanwhile, the relative position of the first gripper 54 and the telescopic platform 53 is adjusted in the same way as above so that the distal hook groove of the first gripper 54 can hook the lithium battery clamp. After the first gripper 54 is adjusted into place, the two grippers 54 continue to hook the lithium battery clamp simultaneously. The above action process is repeated so that the two grippers 54 hook the lithium battery clamp in an alternating manner until the lithium battery clamp is moved from the baking chamber 12 onto the telescopic platform 53. Obviously, in the process of gripping or hooking the lithium battery fixture using the gripper 54 in this embodiment, the range of motion of the gripper 54 and the required space are extremely narrow. The space required for the movement of the gripper 54 can be utilized by the gap between the lithium battery fixture and the baking chamber inside the baking box 12, or by the gap inside the lithium battery fixture, which greatly improves the utilization rate of the limited space in the production workshop.

[0057] The process of moving the lithium battery clamp in is the reverse of the process of moving it out, and will not be described in detail here.

[0058] The horizontal movement of the telescopic platform 53 can be achieved by setting a screw and nut transmission structure, and the vertical movement can be achieved by setting a small cylinder. For example, the gripper 54 can be fixed to the movable end of the small cylinder, and the fixed end of the small cylinder can be set on the connecting plate. The connecting plate is fixedly connected to the screw and nut.

[0059] To ensure the accuracy of the gripper 54's displacement in both the horizontal and vertical directions, a slide rail and slider structure can be used. For example, in the above embodiment, to improve the accuracy of the gripper 54's vertical displacement, a slide rail or groove can be provided on the connecting plate, and a slider can be provided on the gripper 54, allowing the slider to slide within the slide rail or groove; similarly, the accuracy of the gripper 54's horizontal displacement can also be controlled by using a similar structure.

[0060] In another embodiment, the track 11 has multiple preset positions, which are located directly in front of each baking box 12 or cooling box 13. The car 51 is used to travel along the first preset trajectory on the track 11 and reach the preset position. An adjustment plate 91 is provided below the telescopic platform 53. A rotary bearing is provided between the adjustment plate 91 and the lifting platform 52. The car also includes a drive cylinder. The telescopic end of the drive cylinder is hinged to the adjustment plate 91, and the fixed end of the drive cylinder is hinged to the telescopic platform 53.

[0061] Taking the grabbing of a lithium battery clamp located inside the baking chamber 12 as an example, before grabbing, the car 51 first moves along the track 11 to one of the preset positions, opens the sliding door of the baking chamber 12, and adjusts the height of the telescopic platform 53 so that the height of the upper surface of the telescopic platform 53 is the same as the height of the bottom surface of the baking chamber of the baking chamber 12. The telescopic platform 53 then moves horizontally along a second preset trajectory within a preset range through the openings on either side of the car 51, approaching the baking chamber 12 located on different sides of the track 11. When the telescopic platform 53 moves to the entrance / exit point of the baking chamber 12 for the lithium battery clamp, without colliding with the baking chamber 12, the gripper 54 grabs the lithium battery clamp located inside the baking chamber of the baking chamber 12 and moves it onto the telescopic platform 53. The specific grabbing action is as described above and will not be repeated here.

[0062] The preset range can be determined based on the relative positions of the track 11 and the baking chamber 12. It is understood that the preset range is slightly larger than or equal to the shortest distance between the car 51 and the baking chamber 12. This layout can improve the utilization rate of the limited space in the production workshop.

[0063] Furthermore, when the car 51 reaches the preset position, there is still a deviation between it and the lithium battery inlet / outlet of the baking chamber 12. For example, the lithium battery baking clamp itself is already tilted when it is placed into the baking chamber 12. Even if one side of the cuboid baking chamber of the baking chamber 12 is set parallel to the length direction of the track 11, or in other words, one side of the cuboid baking chamber is in the same horizontal movement direction as the hook-type gripper 54 of the telescopic platform 53, the two grippers 54 cannot hook the lithium battery clamp synchronously due to the tilt of the lithium battery clamp itself. Therefore, it is necessary to adjust the telescopic platform 53 to adapt to the placement posture of the lithium battery clamp in the baking chamber 12. By adjusting the relative position of the telescopic platform 53, the problem of difficulty in taking out the lithium battery clamp from the baking chamber 12 caused by the placement deviation is overcome.

[0064] Specifically, when it is necessary to adjust the relative position of the telescopic platform 53 and the baking chamber 12, the telescopic platform 53 can be rotated at a certain angle relative to the baking chamber 12 so that the telescopic platform 53 is aligned with the inlet and outlet of the lithium battery in the baking chamber 12, thus overcoming the problem of difficulty in removing the lithium battery caused by the placement deviation of the lithium battery clamp.

[0065] In the above embodiment, a plurality of support parts for supporting the adjustment plate 91 are provided between the adjustment plate 91 and the lifting platform 52.

[0066] Furthermore, the support includes multiple sets of fixed supports disposed on the upper surface of the lifting platform 52. Each fixed support is equipped with a bearing, which is used to contact the bottom of the adjusting plate 91 and support the rotation of the adjusting plate 91 relative to the lifting platform 52. The fixed supports can be evenly arranged on a predetermined circumference centered on the slewing bearing.
