Description

Technical Field

[0001] This invention relates to the field of battery cell stacking diaphragm flipping technology, specifically to a high-speed battery cell diaphragm stacking machine flipping platform. Background Technology

[0002] During the cell stacking process, the outermost layer is covered by a separator layer. The stacking machine controls the separator to move left and right and presses electrode sheets onto the separator so that the separator and electrode sheets are stacked sequentially. In the existing stacking machine equipment, after completing the stacking of the previous cell, the conveyed separator needs to be cut. The direction of the cut separator is not in the initial position of the stacking. At this time, the separator needs to be flipped.

[0003] For example, patent CN113241468B discloses a stacking mechanism and method for diaphragm flipping and covering. The stacking mechanism includes a stacking table, a feeding assembly, and a diaphragm flipping and covering assembly. The feeding assembly can move closer to or away from the stacking table. The diaphragm flipping and covering assembly includes a fixed support plate and a flipping suction plate that is movably connected to the end of the fixed support plate near the stacking table and can be flipped and pressed onto the fixed support plate. The stacking method is based on the above-mentioned stacking mechanism. After the last electrode of the electrode cell is stacked on the stacking table, the electrode cell can be transferred to the fixed support plate of the diaphragm flipping and covering assembly while the diaphragm is stretched. After the stretched diaphragm is cut, the flipping suction plate covers the cut diaphragm onto the surface of the last electrode of the electrode cell, and the first electrode of the next electrode cell is stacked simultaneously. This greatly shortens the auxiliary time between the stacking processes of two electrode cells and improves production efficiency.

[0004] For example, patent CN111162306B discloses a lithium-ion secondary battery, its electrode stacked cell, and a cell stacking method. The method includes taking a primary electrode assembly, placing a first positive electrode on one side of the separator, and placing a first negative electrode on the other side of the separator to form a primary electrode assembly; obtaining a central stacked assembly, rotating the primary electrode 180° around the rotation axis so that the separator covers the first positive electrode and the first negative electrode, and forming a central stacked assembly; obtaining an outer stacked assembly, placing a second positive electrode and a second negative electrode on both sides of the separator covering the central stacked assembly, rotating the central stacked assembly 180° around the rotation axis so that the separator covers the second positive electrode and the second negative electrode, and forming an outer stacked assembly. It adopts an overall folding and wrapping form to avoid the technical problems of short battery life and low safety performance caused by lithium plating, and improves the battery life and input / output characteristics.

[0005] For example, patent CN207269043U discloses a separator flipping system for lithium battery lamination, which consists of a film-laying device and a stacking platform that moves left and right. The film-laying device, equipped with a separator flipping mechanism, is located above the stacking platform and is situated on the left side of the film-laying device. The separator flipping mechanism includes an air-blowing pipe for blowing the separator from the film-laying device onto the stacking platform. The separator flipping mechanism at the lower end of the film-laying device includes air-blowing pipes fixed to both ends of the guide rollers. When air is supplied, the cut end of the separator can be blown from the right side of the film-laying device onto the stacking platform on the left side of the film-laying device, ready for further processing. The processing of a battery cell; the lower part of the membrane placement device is equipped with a membrane pressing assembly; this facilitates automatic correction after the diaphragm is flipped, enabling a stacking process with no tail roll of the battery cell and saving on the amount of diaphragm used; traditionally, the diaphragm flipping adopts a gas flipping mechanism. When the gas flipping mechanism is working, the airflow may carry impurities in the air, such as dust, metal shavings, fibers, etc. Once these impurities adhere to the diaphragm, they will cause diaphragm contamination, which will affect the performance of the battery cell. In addition, during the gas flipping process, the airflow distribution on the diaphragm surface may be uneven, resulting in inconsistent stress on different parts of the diaphragm, which can easily lead to wrinkles, folds and other phenomena.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing cell stacking and separator flipping platform. Summary of the Invention

[0007] The purpose of this invention is to provide a high-speed separator stacking machine flipping platform for battery cells, in order to solve the problem mentioned in the background art that the traditional separator flipping mechanism uses a gas flipping mechanism. When the gas flipping mechanism is working, the airflow may carry impurities in the air, such as dust, metal shavings, fibers, etc. Once these impurities adhere to the separator, they will cause separator contamination, thereby affecting the performance of the battery cell. In addition, during the gas flipping process, the airflow distribution on the separator surface may be uneven, resulting in inconsistent stress on different parts of the separator, which can easily lead to problems such as wrinkles and folds.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

A support frame is fixedly mounted on the processing platform, and a separator feeding mechanism is provided on the support frame. The separator feeding mechanism includes a feeding shaft rotatably mounted on the support frame, and multiple guide shafts are provided on the support frame to guide the separator's transmission path. A dual-axis control assembly for controlling the left and right flipping direction of the separator is mounted on the support frame below the guide shafts. A mounting frame is fixed on the support frame, and a flipping mechanism for mechanically stabilizing and switching the separator stacking direction is provided on the mounting frame. A power component for driving the flipping mechanism to move laterally is provided on the support frame.

[0010] Preferably, the power assembly includes a slide bar fixed on a mounting bracket, a sliding frame slidably mounted on the slide bar, a movable block fixedly mounted on the sliding frame, and a flipping mechanism mounted on the movable block; a threaded rod is rotatably connected to the mounting bracket, and the movable block is threadedly sleeved on the outside of the threaded rod.

[0011] Preferably, the flipping mechanism includes a fixed shaft fixedly connected to the movable block, the fixed shaft being arranged in a direction parallel to the axis of the guide shaft; a rotating cylinder is rotatably sleeved on the movable block, a sliding frame is fixedly installed on the rotating cylinder, a sliding column is slidably connected through the sliding frame, a movable shaft is fixedly installed on the sliding column, and a pressure rod is fixedly installed on the movable shaft.

[0012] Preferably, the rotation range of the rotating drum is 0-90°, and the rotation of the rotating drum drives the movable shaft and the pressure rod to switch between the horizontal and vertical planes, and the pressure rod is arranged between the movable shaft and the fixed shaft.

[0013] Preferably, the support frame is provided with a clamping mechanism that drives the flipping mechanism to hold and stretch the diaphragm. The clamping mechanism can stretch the diaphragm to eliminate wrinkles and adjust the tension of its stacked sheets.

[0014] Preferably, the clamping mechanism includes a gear ring fixedly sleeved on the outside of the rotating drum, and a rack fixedly mounted on the mounting frame, wherein the gear ring moves laterally and meshes with the rack.

[0015] Preferably, the support frame is provided with a transverse slide rail, and a groove is provided through the side of a part of the transverse slide rail, the position of the groove corresponding to the position of the rack; a protrusion is fixedly installed on the outside of the rotating cylinder, and a cylindrical slide rod is fixedly connected to the protrusion. The cylindrical slide rod is slidably connected in the transverse slide rail, and the cylindrical slide rod is off-axis and located next to the rotating cylinder.

[0016] Preferably, a vertical rod is fixedly installed in the sliding frame, a sliding column is slidably sleeved on the outside of the vertical rod, and a return spring is elastically connected between the sliding column and the sliding frame.

[0017] Preferably, a transmission bracket is fixed on the mounting bracket, and a transmission column is fixed at the end of the sliding column away from the moving shaft, with the transmission column pressed tightly against the side of the transmission bracket.

[0018] Preferably, a primary inclined slide is provided on one side of the transmission bracket, a secondary inclined slide is provided on the other side of the transmission bracket, and a horizontal slide is provided between the primary and secondary inclined slides; the transmission column slides along the direction of the primary inclined slide, the horizontal slide and the secondary inclined slide.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The high-speed diaphragm stacking machine flipping platform for this battery cell uses mechanical force to switch the diaphragm flipping. After a set of battery cells is stacked, the diaphragm is cut and the stacking module is controlled to move and reset. The flipping mechanism then pushes the diaphragm to move and flip. This flipping method does not cause contamination to the diaphragm surface and the way the diaphragm is controlled to flip is relatively stable, avoiding wrinkles or folds in the flipped diaphragm.

[0021] The mounting frame is equipped with a mechanically stable flipping mechanism that switches the direction of the diaphragm stacking. Under the transmission action of the threaded rod and the moving block, the flipping mechanism is driven to move laterally through the moving block. The flipping mechanism is attached to one side of the diaphragm. During its lateral movement, it can push the diaphragm to move closer to the platform of the stacking module. The diaphragm is flipped over by mechanical pushing, keeping the diaphragm flipped to the initial processing position of the stacking process after cutting.

[0022] The main body of the flipping mechanism includes a fixed shaft, a movable shaft, and a pressure rod. During the process of laterally pushing the diaphragm to reset, the fixed shaft, the movable shaft, and the pressure rod are supported below the diaphragm. Their support surface is relatively wide, which can push the diaphragm to flip and reset relatively stably.

[0023] The support frame is equipped with a drive flipping mechanism to clamp and stretch the diaphragm. When the diaphragm is pushed laterally to the surface of the stacking module, under the meshing transmission of the gear ring and rack, the rotating cylinder controls the sliding frame, sliding column, moving shaft, and pressure rod to rotate from a horizontal state to a vertical state, so that the moving shaft and pressure rod are above the diaphragm, while the fixed shaft is below the diaphragm. As the moving block continues to move laterally, under the contact and pressing transmission of the transmission bracket and transmission column, the moving shaft and pressure rod can be controlled to move downward, so that the pressure rod presses down on the diaphragm surface, and the diaphragm is pressed and limited between the pressure rod and the fixed shaft. When the pressure rod and the fixed shaft continue to move laterally, they can drive the clamped diaphragm moving cabinet to tighten, thereby adjusting the output tension of its winding between the guide shafts, keeping the diaphragm stably stretched and set above the stacking module for subsequent stacking processing operations, and avoiding wrinkles or folds on the surface of the diaphragm after flipping.

[0024] After the transmission column moves from the horizontal slide on the transmission bracket to the secondary inclined slide, the pressure rod and the moving shaft move upward under the elastic thrust of the return spring, thereby realizing the autonomous separation of the pressure rod and the fixed shaft. This allows the pressure rod and the fixed shaft to move and separate autonomously from the diaphragm after clamping and stretching it, so that this part of the structure can move to one side of the stacking module without affecting the cell stacking process, allowing the stacking process to be carried out continuously.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a high-speed battery cell separator stacking machine flipping platform, comprising a processing platform 1 and an electric slide rail assembly 2 fixedly installed on the processing platform 1, a moving platform 3 installed on the sliding end of the electric slide rail assembly 2, a stacking module 4 for processing battery cells installed on the moving platform 3, a support frame 5 fixedly installed on the processing platform 1, a separator feeding mechanism provided on the support frame 5, the separator feeding mechanism including a feeding shaft 6 rotatably installed on the support frame 5, and multiple guide shafts 7 for guiding the separator transmission path provided on the support frame 5, a control dual-axis assembly 8 for controlling the left and right flipping direction of the separator installed below the guide shafts 7 on the support frame 5; a mounting frame 9 fixedly installed on the support frame 5, a flipping mechanism 10 for mechanically stabilizing and switching the separator stacking direction provided on the mounting frame 9, and a power component for driving the flipping mechanism 10 to move laterally on the support frame 5.

[0040] Please see Figures 3-10 The power assembly includes a slide bar 91 fixed on the mounting bracket 9, a sliding frame 92 slidably mounted on the slide bar 91, a moving block 93 fixedly mounted on the sliding frame 92, and a tilting mechanism 10 mounted on the moving block 93; a threaded rod 94 is rotatably connected to the mounting bracket 9, and the moving block 93 is threadedly sleeved on the outside of the threaded rod 94; the tilting mechanism 10 includes a fixed shaft 101 fixedly connected to the moving block 93, the fixed shaft 101 being parallel to the axis of the guide shaft 7; the moving block 93... The upper rotating sleeve is equipped with a rotating cylinder 102, and a sliding frame 103 is fixedly installed on the rotating cylinder 102. A sliding column 104 is slidably connected through the sliding frame 103. A movable shaft 105 is fixedly installed on the sliding column 104, and a pressure rod 106 is fixedly installed on the movable shaft 105. The rotation range of the rotating cylinder 102 is 0-90°, and the rotation of the rotating cylinder 102 drives the movable shaft 105 and the pressure rod 106 to switch between the horizontal and vertical planes. The pressure rod 106 is located between the movable shaft 105 and the fixed shaft 101.

[0041] The diaphragm roll is installed outside the feeding shaft 6, and the stretched diaphragm is wound around the outside of multiple guide shafts 7. Finally, the diaphragm passes through the directional dual-shaft group 8 and is stretched onto the stacking module 4. During the stacking process, the moving platform 3 and the stacking module 4 are controlled to move laterally and reciprocally by the electric slide rail group 2. The components on the stacking module 4 are pressed against the diaphragm surface, so that the diaphragm moves synchronously with the stacking module 4. During the left and right movement of the diaphragm, the direction of the diaphragm is restricted by the directional dual-shaft group 8, so that the diaphragm is continuously stacked above the stacking module 4. During the stacking process, electrode sheets are pressed onto the diaphragm to form a battery cell stack. The number of layers of the diaphragm stack is controlled according to the required height of the battery cell stack. When a battery cell stack is completed, the diaphragm is cut by the cutting equipment, and the completed battery cell stack is removed from the stacking module 4, completing the processing of a battery cell stack. At this time, the direction of the diaphragm is not the initial direction of the stack, and the diaphragm needs to be flipped.

[0042] The control module 4 is moved and reset, and the motor on the mounting bracket 9 controls the rotation of the threaded rod 94. The moving block 93 is threadedly connected to the threaded rod 94. Under the threaded transmission, the moving block 93 can drive the flipping mechanism 10 to move synchronously laterally. The flipping mechanism 10 moves from the left side of the diaphragm to the right side of the diaphragm, and then the moving block 93 drives the flipping mechanism 10 to move in the opposite direction. The moving shaft 105 on the flipping mechanism 10 first contacts the diaphragm surface, pushing the diaphragm to move closer to the reset stacked module 4 (e.g., ...). Figure 5 As shown), when the diaphragm is pushed above the stacking module 4, the moving shaft 105, the pressure rod 106, and the fixed shaft 101 in the flipping mechanism 10 are all supported below the diaphragm (as shown). Figure 6 As shown in the figure, its pushing direction has a wide range, which can stably assist the diaphragm to flip onto the surface of the stacking module 4. The flipping mechanism 10 controls the diaphragm flipping in a way that will not contaminate the diaphragm surface and can push the diaphragm flipping relatively stably, thereby improving the stacking processing quality.

[0043] Example 2: Please refer to Figures 6-12 Based on Embodiment 1, a clamping mechanism is also disclosed, the specific structure of which is as follows: a clamping mechanism for holding and stretching the diaphragm is provided on the support frame 5, the clamping mechanism can stretch the diaphragm to eliminate wrinkles and adjust the tension of its stacked sheets; the clamping mechanism includes a toothed ring 15 fixedly sleeved on the outside of the rotating cylinder 102, and a rack 16 fixedly installed on the mounting frame 9, the toothed ring 15 moving laterally and engaging with the rack 16.

[0044] Please see Figures 8-12A transverse slide rail 11 is provided on the support frame 5. A groove 12 is provided through a part of the transverse slide rail 11 on the side. The position of the groove 12 corresponds to the position of the rack 16. A protrusion 13 is fixedly installed on the outside of the rotating cylinder 102. A cylindrical slide rod 14 is fixedly connected to the protrusion 13. The cylindrical slide rod 14 is slidably connected in the transverse slide rail 11 and is off-axis positioned next to the rotating cylinder 102. A vertical rod 17 is fixedly installed in the sliding frame 103. A sliding column 104 is slidably sleeved on the outside of the vertical rod 17. A return spring 18 is elastically connected between the sliding column 104 and the sliding frame 103.

[0045] Please see Figures 8-11 A transmission bracket 20 is fixed on the mounting bracket 9. A transmission column 19 is fixed to one end of the slide column 104 away from the moving shaft 105, and the transmission column 19 is pressed against the side of the transmission bracket 20. A primary inclined slide 201 is provided on one side of the transmission bracket 20, and a secondary inclined slide 202 is provided on the other side of the transmission bracket 20. A horizontal slide 203 is provided between the primary inclined slide 201 and the secondary inclined slide 202. The transmission column 19 slides along the direction of the primary inclined slide 201, the horizontal slide 203 and the secondary inclined slide 202.

[0046] During the lateral movement of the flipping mechanism 10, the cylindrical slide rod 14 on the protrusion 13 moves laterally along the direction of the lateral slide rail 11. When the flipping mechanism 10 pushes the diaphragm to flip and move above the stacking module 4, the gear ring 15 on the rotating cylinder 102 gradually moves closer to the rack 16. After the gear ring 15 moves and meshes with the rack 16, the cylindrical slide rod 14 moves into the groove 12. Under the meshing transmission, the gear ring 15 and the rotating cylinder 102 can be controlled to rotate. The rotating cylinder 102 drives the sliding frame 103, the moving shaft 105, and the pressure rod 106 to rotate from the horizontal state to the vertical state. At this time, the moving shaft 105 and the pressure rod 106 are located above the diaphragm, and the fixed shaft 101 is located below the diaphragm. The column slide rod 14 moves to the transverse slide rail 11 on the other side of the convex groove 12. The slide column 104 is slidably disposed in the vertical slide frame 103. At this time, the transmission column 19 on the slide column 104 is pressed against the transmission bracket 20. The moving block 93 continues to move laterally. The transmission column 19 moves laterally and contacts the first-stage inclined slide rail 201 on the transmission bracket 20. At this time, the transmission column 19 drives the slide column 104 to move downward on the outside of the upright rod 17. The slide column 104 compresses the return spring 18. At this time, the slide column 104 drives the moving shaft rod 105 and the pressure rod 106 to move downward, so that the pressure rod 106 presses against the upper surface of the diaphragm. The diaphragm is clamped and limited between the pressure rod 106 and the fixed shaft rod 101 (e.g., Figure 7As shown, when the flipping mechanism 10 moves laterally, it can clamp and control the diaphragm to stretch laterally, adjust the tension of the diaphragm transmitted between the guide shafts 7, and keep the diaphragm taut and set above the stacking module 4. When the transmission column 19 moves from the horizontal slide 203 to the secondary inclined slide 202, under the elastic thrust of the return spring 18, the transmission column 19 drives the slide column 104, the moving shaft 105 and the pressure rod 106 to move upward, so that the pressure rod 106 loosens the force pressing on the diaphragm. By continuing to control the lateral movement of the flipping mechanism 10, the flipping mechanism 10 can be separated from the diaphragm, thereby realizing the diaphragm flipping and adhering to the upper surface of the stacking module 4. By controlling the flipping of the diaphragm by clamping and stretching, it is possible to avoid wrinkles, folds and other situations on the surface of the diaphragm after the flipping process.
