Description

Technical Field

[0001] This application relates to the field of battery processing technology, and in particular to a stacking machine that eliminates waste separator material at the bottom layer. Background Technology

[0002] In existing lamination processes, when the bottom layer needs to be designed as an electrode, the diaphragm at the bottom must first be cut and discarded. However, current waste disposal methods have some technical shortcomings: existing diaphragm rollers are installed above the stacking platform and can reciprocate, while the stacking platform is fixed. During the process of waste diaphragm grippers grabbing and discarding waste, spatial interference and collisions are very likely to occur with the diaphragm rollers, causing the waste to be unable to be accurately placed into the collection device, affecting the normal operation of the equipment.

[0003] Therefore, there is an urgent need to develop a new solution to address the aforementioned technical issues and improve the reliability and product yield of the wafer stacking process. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a stacking machine without bottom waste diaphragm, thereby improving the reliability of the stacking process and the product yield.

[0005] To achieve the above technical objectives, this application provides a stacking machine for diaphragms without bottom waste, including a diaphragm pulling roller device, a stacking table device, and a stacking table moving device;

[0006] The diaphragm roller device is fixedly installed;

[0007] The stacking device includes a stacking body and a cutting mechanism;

[0008] The cutting mechanism is located at one edge of the stack body;

[0009] The stacking platform moving device is connected to the stacking platform device and is used to drive the stacking platform device to move relative to the diaphragm roller device.

[0010] Furthermore, the diaphragm roller device is disposed above the stacking platform body;

[0011] The stacking platform is a Z-shaped stacking platform.

[0012] Furthermore, the stacking platform moving device includes a first moving mechanism and a second moving mechanism;

[0013] The first moving mechanism is connected to the stacking platform device and is used to drive the stacking platform device to move relative to the diaphragm roller device in the stacking length direction;

[0014] The second moving mechanism is connected to the first moving mechanism and is used to move the stacking platform relative to the diaphragm roller device in the stacking thickness direction by moving the first moving mechanism.

[0015] Furthermore, the cutting mechanism includes a cutting body and a cutting drive mechanism;

[0016] The cutter drive mechanism is arranged parallel to the side of the stacking platform body and connected to the cutter body, and is used to drive the cutter body to move.

[0017] Furthermore, the stacking device also includes a pressure knife;

[0018] The pressure knife is used to press the diaphragm on the stack.

[0019] Furthermore, it also includes waste collection devices;

[0020] The waste collection device is located on one side of the stacking platform device;

[0021] The stacking platform moving device can move the stacking platform closer to or away from the waste collection device.

[0022] Furthermore, the waste collection device includes a waste collection tank and a waste disposal mechanism;

[0023] The waste disposal mechanism is used to grab diaphragm waste at the waste grabbing station and transport it to the waste collection tank.

[0024] Furthermore, the waste disposal mechanism includes waste grippers and a waste moving mechanism;

[0025] The waste moving mechanism is connected to the waste gripper and is used to drive the waste gripper to move between the waste grabbing station and the waste collection tank;

[0026] The waste gripper is used to grab diaphragm waste.

[0027] Furthermore, the waste moving mechanism includes a rocker arm assembly and a rotary drive assembly;

[0028] The swing arm assembly is connected between the rotary drive assembly and the waste gripper;

[0029] The rotary drive assembly is used to drive the swing arm assembly to move, thereby causing the waste gripper to swing.

[0030] The movement trajectory of the waste gripper is tangent to both the stacking platform and the waste collection trough.

[0031] Furthermore, the waste gripper is also equipped with an air blowing assembly for blowing air onto the diaphragm waste on the waste gripper when it is discarded.

[0032] As can be seen from the above technical solutions, the stacking machine without bottom waste diaphragm designed in this application fixes the diaphragm pull roller device and moves the stacking platform device relative to the diaphragm pull roller device through the stacking platform moving device. This allows the diaphragm pull roller device to be avoided when picking up diaphragm waste material, thus avoiding spatial interference and collision with the diaphragm pull roller device, improving the reliability of the stacking process and the product yield, and achieving a fast material cutting and stacking effect.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0043] This application discloses a stacking machine that eliminates waste diaphragm at the bottom layer.

[0044] Please see Figure 1 An embodiment of a stacking machine without a bottom waste diaphragm provided in this application includes:

[0045] The diaphragm roller device 3, the stacking platform device 1, and the stacking platform moving device 2.

[0046] The diaphragm roller device 3 is fixedly installed, and the stacking device 1 includes a stacking body 12 and a cutting mechanism 11, which is located at one edge of the stacking body 12.

[0047] The stacking platform moving device 2 is connected to the stacking platform device 1 and is used to drive the stacking platform device 1 to move relative to the diaphragm roller device 3.

[0048] The bottom-layer waste separator stacking machine designed in this application adopts a novel structural layout. The separator roller device 3 is fixedly installed, while the stacking platform device 1 is connected to the stacking platform moving device 2. This allows the stacking platform device 1 to achieve precise and controllable displacement relative to the fixed separator roller device 3 under the drive of the stacking platform moving device 2. This relative motion design enables the stacking platform device 1 to effectively avoid the working area of ​​the separator roller device 3 during separator waste material handling, thus avoiding spatial interference and the risk of mechanical collision. This design not only significantly improves the overall operational reliability of the stacking process but also effectively reduces equipment failure rate and product defect rate caused by mechanical interference. Furthermore, by optimizing the motion trajectory and shortening the ineffective travel, it achieves high-speed and efficient sheet cutting and stacking operations, providing a superior process solution for power battery production.

[0049] The above is Embodiment 1 of a wafer stacking machine without a bottom layer waste diaphragm provided in this application. The following is Embodiment 2 of a wafer stacking machine without a bottom layer waste diaphragm provided in this application. Please refer to the following for details. Figures 1 to 5 .

[0050] Based on the solution of Embodiment 1 above:

[0051] Furthermore, such as Figure 1 As shown, the diaphragm roller device 3 is positioned above the stacking platform body 12. This layout allows the diaphragm to fall naturally from above onto the stacking platform body 12, which is more conducive to achieving precise stacking operations. Moreover, this layout also facilitates equipment maintenance and repair. The diaphragm roller device 3 and the stacking platform device 1 are relatively independent and have a certain spatial separation, allowing operators to easily inspect, repair, and replace various components, reducing maintenance costs and downtime.

[0052] The stacking platform body 12 in this application can specifically be a Z-type stacking platform (the stacking platform body of a Z-type stacking machine). A Z-type stacking machine is a key piece of equipment in the production of square lithium batteries, mainly used to alternately stack pre-fabricated positive / negative electrode sheets with separators as intervals, forming Z-type stacked cells. It is understood that the improved stacking machine design in this application can be applied to existing Z-type stacking machines; of course, it can also be applied to other stacking machines as needed.

[0053] Furthermore, such as Figure 1 as well as Figure 5As shown, the stacking platform moving device 2 includes a first moving mechanism 21 and a second moving mechanism 22. The first moving mechanism 21 is connected to the stacking platform device 1 and is used to move the stacking platform device 1 relative to the diaphragm roller device 3 in the stacking length direction. The second moving mechanism 22 is connected to the first moving mechanism 21 and is used to move the first moving mechanism 21 to move the stacking platform device 1 relative to the diaphragm roller device 3 in the stacking thickness direction. The first moving mechanism 21 can be a horizontal moving mechanism, while the second moving mechanism 22 can be a lifting moving mechanism.

[0054] Through the coordinated operation of the first moving mechanism 21 and the second moving mechanism 22, the stacking device 1 can move flexibly in two key directions to adapt to the requirements of battery stacking of different specifications and sizes. In actual operation, when different lengths of stacking are required, the first moving mechanism 21 precisely drives the stacking device 1 to move in the stacking length direction to ensure that the length of the separator matches the length of the stacked cells. In the stacking thickness direction, the second moving mechanism 22 can precisely adjust the position of the stacking device 1 according to the number of layers required by the battery to achieve precise thickness control.

[0055] This dual-movement mechanism design makes the stacking process more automated and intelligent. Operators only need to set the relevant parameters according to production requirements, and the first moving mechanism 21 and the second moving mechanism 22 will move according to the predetermined program, greatly improving production efficiency and product quality stability. Moreover, the dual-movement mechanism design enhances the equipment's versatility and adaptability, meeting the diverse needs of different customers for battery stacking. Whether it's small consumer batteries or large power lithium batteries, this stacking machine without a bottom-layer waste separator can achieve efficient and precise stacking operations through the precise control of the first moving mechanism 21 and the second moving mechanism 22.

[0056] In the design and manufacturing process of the moving mechanism, high-precision guide rails, lead screws and drive motors can be used to ensure the stability and accuracy of the stacking device 1 during movement. Those skilled in the art can make design variations according to actual needs without limitation.

[0057] Furthermore, such as Figure 1 As shown, the design of the cutting mechanism 11 includes a cutting body 111 and a cutting drive mechanism 112. The cutting drive mechanism 112 is arranged parallel to the side of the stack body 12 and connected to the cutting body 111, and is used to drive the cutting body 111 to move.

[0058] The design of this cutting mechanism 11 enables the cutting body 111 to smoothly and accurately cut the diaphragm under the drive of the cutting drive mechanism 112. The cutting drive mechanism 112 is arranged laterally parallel to the stacking platform 12, ensuring that the movement path of the cutting body 111 matches the placement direction of the diaphragm on the stacking platform 12, thus achieving efficient cutting operations. The cutting drive mechanism 112 can employ a linear motor, cylinder, or other power device to provide stable and controllable driving force, ensuring that the cutting body 111 can complete the cutting action quickly and accurately.

[0059] In addition, the design of the cutter drive mechanism 112 and the cutter body 111 can be flexibly adjusted according to different battery production needs, such as adjusting parameters such as cutting speed and cutting length, to meet diverse production requirements.

[0060] The cutting mechanism 11 can be designed or reused from existing cutting modules, so it will not be described in detail here.

[0061] Furthermore, such as Figure 1 As shown, the stacking device 1 also includes a pressure knife 13, which is used to press the diaphragm on the stacking platform.

[0062] The pressure knife 13 effectively prevents the diaphragm from shifting or wrinkling during stacking, thus ensuring the quality of the stacked membranes. Once the diaphragm is placed on the stacking table, the pressure knife 13 quickly presses down, firmly fixing the diaphragm to the table, allowing for more precise subsequent cutting and stacking operations. The pressure knife 13 can be pneumatically or electrically driven to achieve fast and stable clamping action. The structure and driving method of the pressure knife 13 are existing designs and will not be described in detail.

[0063] Furthermore, such as Figure 2 as well as Figure 3 As shown, it also includes a waste collection device 4; the waste collection device 4 is located on one side of the stacking device 1; the stacking device moving device 2 can drive the stacking device 1 to move closer to or away from the waste collection device 4. It can be understood that the waste collection device 4 and the stacking device 1 move closer or further away from each other through the first displacement mechanism, so as to avoid the diaphragm roller device 3 above the stacking body 12.

[0064] Furthermore, such as Figure 2 as well as Figure 3 As shown, the waste collection device 4 includes a waste collection tank 41 and a waste disposal mechanism 42; the waste disposal mechanism 42 is used to grab diaphragm waste at the waste grabbing station and transport it to the waste collection tank 41.

[0065] The waste disposal mechanism 42 is designed to promptly remove diaphragm waste generated during the lamination process, preventing waste accumulation from affecting normal equipment operation. At the waste grabbing station, the waste disposal mechanism 42 precisely grabs the diaphragm waste and then quickly transports it to the waste collection tank 41. This operation process makes waste removal efficient and orderly, ensuring the continuity of the lamination operation.

[0066] The design of the waste collection tank 41 should take into account the storage capacity of the waste and the ease of cleaning. The size and shape of the waste collection tank 41 can be reasonably designed according to the amount of diaphragm waste generated in actual production. At the same time, in order to facilitate the cleaning of waste, the waste collection tank 41 can adopt a detachable or flip-up structure so that the staff can easily remove the collected waste.

[0067] Furthermore, such as Figures 2 to 4 As shown, the waste disposal mechanism 42 includes a waste gripper 421 and a waste moving mechanism 422; the waste moving mechanism 422 is connected to the waste gripper 421 and is used to drive the waste gripper 421 to move between the waste grabbing station and the waste collection tank 41; the waste gripper 421 is used to grab diaphragm waste.

[0068] Specifically, when the cutter cuts the diaphragm, the waste gripper 421 clamps the free end of the diaphragm, the pressure knife 13 presses the diaphragm firmly, and the cutter, positioned between the waste gripper 421 and the pressure knife 13, lifts up to cut the diaphragm. The waste gripper 421 then holds the waste diaphragm material and throws it into the waste collection trough 41. This cooperation between the waste gripper 421 and the waste moving mechanism 422 automates the grabbing and transporting of diaphragm waste. The waste moving mechanism 422 can be designed with different motion forms according to actual needs, such as linear motion, rotary motion, or a combination of both. Through precise control, the waste moving mechanism 422 can accurately move the waste gripper 421 to the waste grabbing station and the waste collection trough 41, ensuring that the diaphragm waste is efficiently cleaned.

[0069] Traditional waste collection troughs 41 are typically located adjacent to the side of the stacking device 1. This layout makes it easy for dust to fly during the disposal of diaphragm waste. These tiny particles can spread to the working area of ​​the stacking device 1, causing secondary pollution to the stacked electrodes or diaphragms and seriously affecting product quality. To solve the above problems, the waste moving mechanism 422 of this application includes a swing arm assembly 4221 and a rotary drive assembly 4222. The swing arm assembly 4221 is connected between the rotary drive assembly 4222 and the waste gripper 421. The rotary drive assembly 4222 is used to drive the swing arm assembly 4221 to move, thereby causing the waste gripper 421 to swing. The movement trajectory of the waste gripper 421 is tangent to both the stacking body 12 and the waste collection trough 41. By using the rotary drive assembly 4222 to drive the waste gripper 421 to swing, the gripping and disposal of the waste gripper 421 can be adjusted at multiple angles, avoiding dust and secondary pollution.

[0070] Furthermore, the coordinated design of the rotary drive assembly 4222 and the swing arm assembly 4221 enables precise control of the movement trajectory of the waste gripper 421. In actual operation, the rotary drive assembly 4222 can flexibly adjust the swing angle and speed of the waste gripper 421 according to different production needs, allowing the waste gripper 421 to reach the waste grabbing station and waste collection tank 41 more accurately. This precise control not only improves the efficiency of waste cleaning but also further reduces problems such as waste falling due to inaccurate movement of the waste gripper 421.

[0071] Meanwhile, the structural design of the waste gripper 421 is also crucial. To better grip the diaphragm waste, the waste gripper 421 can utilize special materials and surface treatment processes to increase the friction between it and the diaphragm waste, ensuring that the waste does not easily fall off during gripping and transport. Furthermore, the opening and closing action of the waste gripper 421 can be achieved through a high-precision drive device, ensuring that the opening and closing force and speed can be adjusted according to actual conditions, thus adapting to different types and sizes of diaphragm waste.

[0072] In addition, auxiliary devices such as dust collection devices or filtration devices can be installed inside the waste collection tank 41. The dust collection device can promptly remove dust generated during waste collection, further reducing the impact of dust on the working environment and product quality. The filtration device can filter the intake air, preventing dust from being emitted into the external environment and achieving environmentally friendly production.

[0073] Furthermore, such as Figure 3 As shown, the waste gripper 421 is also equipped with an air blowing assembly 43, which is used to blow air onto the diaphragm waste on the waste gripper 421 when it is discarded, so that the diaphragm waste falls off quickly and to remove dust from the waste gripper 421.

[0074] The air blowing assembly 43 further optimizes the waste disposal process. When the waste gripper 421 reaches above the waste collection trough 41 to dispose of the diaphragm waste, the air blowing assembly 43 activates. An airflow acts on the diaphragm waste, allowing it to quickly separate from the gripper 421 and fall into the collection trough 41. Simultaneously, the airflow also blows off fine dust adhering to the gripper 421, achieving a good dust removal effect, ensuring the cleanliness of the gripper 421, and preventing dust from affecting the stability of gripping the diaphragm waste during subsequent handling.

[0075] The air source for the air blowing assembly 43 can be selected from various sources, such as compressed air tanks or air compressors. During actual production, the operating status of the air blowing assembly 43 can be monitored in real time. Through sensors and other equipment, any malfunctions or abnormal airflow in the air blowing assembly 43 can be detected promptly, allowing for timely maintenance and adjustments to ensure the normal operation of the entire waste collection system.

[0076] The above provides a detailed description of a stacking machine without a bottom waste diaphragm provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
