Description

Technical Field

[0001] This invention relates to the field of battery processing technology, specifically to a novel general-purpose semi-automatic aluminum-plastic film folding and pressing machine for lithium batteries. Background Technology

[0002] Lithium-ion batteries are a new generation of high-performance, green, and high-energy batteries, and have become a key focus of high-tech development. Lithium-ion batteries possess the following characteristics: high voltage, high capacity, low power consumption, no memory effect, no pollution, small size, low internal resistance, low self-discharge, and a high cycle life. Due to these characteristics, lithium-ion batteries are widely used in numerous civilian and military fields, including mobile phones, laptops, and tablets.

[0003] In the production process of soft-pack lithium batteries, the battery cells generally need to be packaged. In the traditional lithium battery production process, the battery packaging technology and methods are usually as follows: first, the rolled aluminum-plastic film is cut into sheets by hand or semi-automatic machinery, then punched and trimmed to form packaging bags. Then, the battery cells are manually placed into the packaging bags, the packaging bags are folded to cover the battery cells, and the packaging bags and battery cells are transferred to the top sealing and side sealing machines to complete the top and side sealing. The existing packaging method is generally to fold the sides and then heat press them. In the current battery production process, two separate stations are usually used to perform the folding and heat pressing work. The battery cells need to be manually or automatically moved between processes, which is time-consuming and labor-intensive. At the same time, because the aluminum-plastic film is elastic, it is easy for the battery cells to spring back after the folding driving force is removed, resulting in low folding accuracy. It is also easy for the cells to be skewed during heat pressing, resulting in low battery aesthetics and low sealing level. Summary of the Invention

[0004] The technical problem to be solved by this invention is that in the existing battery manufacturing process, two separate workstations are generally used to perform the folding and hot pressing work. The cells need to be moved manually or by automated equipment between processes, which is time-consuming and labor-intensive. At the same time, the aluminum-plastic film is elastic after the cells are folded, and it is easy for them to spring back after the folding driving force is removed, resulting in low folding accuracy. Furthermore, the cells are prone to skewing during hot pressing, which leads to low aesthetics and sealing level of the battery.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a novel general-purpose semi-automatic aluminum-plastic film folding and pressing machine for lithium batteries, comprising a folding and pressing mechanism for sequentially completing the folding and pressing of lithium batteries, and a battery limiting mechanism for installing batteries and cooperating with the folding and pressing mechanism during battery folding and pressing. The battery limiting mechanism has a battery mounting station for installing batteries. The folding and pressing mechanism has at least one folding and pressing component, which is arranged around the battery mounting station. The folding and pressing component has a heating part and a folding and pressing part for sequentially folding and pressing the edge of the aluminum-plastic film. The heating part of the folding and pressing component heats the aluminum-plastic film according to preset control parameters. The folding and pressing part of the folding and pressing component is aligned with the battery mounting station and cooperates with the folding and pressing mechanism to sequentially complete the folding and pressing of lithium batteries in one operation.

[0006] In operation, this invention integrates the folding and hot-pressing processes into a single mechanism, enabling the folding and hot-pressing of lithium batteries to be completed in one go. This reduces the time spent transferring and waiting batteries between different workstations, avoids secondary positioning, and prevents repeated alignment errors, thereby significantly improving battery production efficiency and folding / pressing accuracy. Simultaneously, it allows for preheating of the aluminum-plastic film during folding, reducing folding stress and preventing cracks or springback in the film. This ensures that the pressed battery folds have high structural strength and a high sealing rating. Furthermore, through the cooperation between the integrated folding / pressing mechanism and the battery limiting mechanism, it can be easily adapted to different battery specifications based on actual needs, making it widely applicable.

[0007] Preferably, the folding and ironing integrated mechanism further includes a folding and ironing fixing frame, a folding and ironing sliding frame, and a dual-stroke folding and ironing drive assembly. The folding and ironing fixing frame is arranged around the battery installation station and extends towards the battery installation station. The folding and ironing sliding frame is slidably and limitedly mounted on the folding and ironing fixing frame along the extension direction of the folding and ironing fixing frame. The folding and ironing assembly is connected to the output part of the dual-stroke folding and ironing drive assembly through a transmission assembly and is mounted on the folding and ironing fixing frame through the dual-stroke folding and ironing drive assembly.

[0008] When this invention is in operation, the dual-stroke folding and pressing drive assembly drives the two different working strokes of folding and pressing respectively, which can achieve precise sequence control. At the same time, it allows the folding and pressing sliding frame to be adjusted along the folding and pressing fixed frame, which can easily adjust the relative position of the folding and pressing assembly and the battery installation station according to actual needs. It is applicable to batteries of different specifications and has high transmission accuracy and high action repeatability.

[0009] Preferably, the folding and ironing assembly includes a folding and ironing bracket, a folding and ironing section, and a heating component. The folding and ironing section extends along the edge of the aluminum-plastic film and is connected to the output part of the dual-stroke folding and ironing drive assembly via the folding and ironing bracket. The heating part of the heating component is embedded inside the folding and ironing section and dynamically adjusts the temperature of the folding and ironing section according to preset control parameters when the folding and ironing section performs the edge folding and ironing work of the lithium battery. The folding and ironing section operates under the drive of the dual-stroke folding and ironing drive assembly to complete the edge folding and ironing work of the lithium battery in sequence in one go.

[0010] Preferably, the folding and ironing assembly further includes a heat insulation component, which is arranged around the periphery of the folding and ironing part. The folding and ironing part is mounted on the folding and ironing bracket through the heat insulation component, and the heat insulation component has an opening on the side near the battery mounting station for the folding and ironing part to be exposed to the outside.

[0011] In operation, this invention completes the folding and pressing of lithium batteries in one go through the folding and pressing section with embedded heating components, driven by a dual-stroke folding and pressing drive component. It features high heat conduction efficiency, rapid heating, and convenient precise temperature control. The temperature can be dynamically adjusted according to different processing stages or aluminum-plastic film materials, offering strong adaptability. Simultaneously, the aluminum-plastic film can be preheated during the folding process, improving the folding effect and ensuring the shape of the folding and pressing section matches the edge of the aluminum-plastic film. This guarantees the continuity and fit of the folding and pressing work. The use of heat insulation components allows for precise control of the contact area between the folding and pressing section and the battery, preventing overheating of the battery, improving finished product quality, and helping to adjust and maintain the preset pressing temperature of the folding and pressing section, thus enhancing process stability.

[0012] Preferably, the dual-stroke folding and ironing drive assembly includes a first folding and ironing drive device, a fixed reinforcing plate, and a second folding and ironing drive device. The first folding and ironing drive device is installed on the top of the folding and ironing sliding frame, and the second folding and ironing drive device is installed on the output part of the first folding and ironing drive device through the fixed reinforcing plate. The output part of the second folding and ironing drive device is connected to the folding and ironing assembly in a transmission manner. The first folding and ironing drive device and the second folding and ironing drive device operate according to preset control parameters to drive the folding and ironing part to complete the folding and ironing work of the lithium battery in sequence in one go.

[0013] Preferably, the folding and ironing integrated mechanism further includes a correction component for correcting the position of the lithium battery before performing the lithium battery folding and ironing work. The correction component is installed on the folding and ironing sliding frame and is connected to the battery driving mechanism on the battery limiting mechanism to drive the battery to move into the battery installation station before performing the lithium battery folding and ironing work.

[0014] Preferably, the correction assembly includes a correction guide rail, a correction slide, a correction part, and a correction drive device. The correction guide rail is mounted on the folding and pressing sliding frame and extends along the direction close to the battery mounting station. The correction part is slidably limited and mounted on the correction guide rail via the correction slide and is connected to the output part of the correction drive device via a transmission assembly. Before performing lithium battery folding and pressing, the correction part is connected to the battery on the battery limiting mechanism under the drive of the correction drive device according to the corresponding control command, and drives the battery to move into the battery mounting station.

[0015] When this invention is in operation, it can eliminate positional deviations caused by manual feeding or previous processes, ensuring that the folding and pressing components always act on the correct edge of the aluminum-plastic film, thereby avoiding defects such as uneven folding and misaligned pressing caused by battery misalignment, reducing scrap rate, and also reducing the labor intensity of operators, reducing manual intervention, and improving production efficiency.

[0016] Preferably, the folding and ironing integrated mechanism further includes a guide component, which is mounted on the folding and ironing component, and the folding and ironing component abuts against a corresponding guide base through the guide component.

[0017] Preferably, the battery limiting mechanism includes a limiting mounting frame, an upper mounting plate, a lower mounting plate, an upper mounting drive device, and a lower mounting drive device. The upper mounting plate and the lower mounting plate are arranged vertically and alternately inside the limiting mounting frame and are respectively connected to the upper mounting drive device and the lower mounting drive device. The upper mounting plate and the lower mounting plate cooperate with each other under the drive of the upper mounting drive device and the lower mounting drive device to form a battery mounting station for installing batteries.

[0018] When this invention is in operation, the lifting upper and lower mounting plates, together with the folding and pressing integrated mechanism, complete the folding and pressing of the lithium battery in sequence in one go. The distance between the upper and lower mounting plates is adjustable, which can hold lithium batteries of different thicknesses. It is highly versatile and can easily change the position of the battery installation station according to actual needs. At the same time, the lifting upper and lower mounting plates also provide more space for inserting and removing the battery, and the operation window facilitates semi-automatic operation.

[0019] Preferably, the system also includes a mounting plate, a protective cabinet, an operation panel, and an operation table. Both the folding and ironing mechanism and the battery limiting mechanism are mounted on the mounting plate. The protective cabinet is mounted on the mounting plate and covers the periphery of the folding and ironing mechanism and the battery limiting mechanism. The front of the protective cabinet has an operation window that exposes the battery mounting position of the battery limiting mechanism to the outside. The operation panel is mounted on the top front of the protective cabinet and is electrically connected to both the folding and ironing mechanism and the battery limiting mechanism to drive them according to preset control parameters. The operation table is mounted on the mounting plate and located near the operation window. The operation panel has an indicator section for displaying the working status of the folding and ironing mechanism and the battery limiting mechanism. Both the operation panel and the operation table have control buttons for controlling the operation of the folding and ironing mechanism and the battery limiting mechanism.

[0020] The beneficial technical effects of this invention include:

Simultaneously, it allows for preheating of the aluminum-plastic film during folding, reducing folding stress and preventing cracks or springback in the film. This ensures that the pressed battery folds have high structural strength and a high sealing rating. Furthermore, through the cooperation between the integrated folding / pressing mechanism and the battery limiting mechanism, it can be easily adapted to different battery specifications based on actual needs, making it widely applicable.

It is applicable to batteries of different specifications and has high transmission accuracy and high action repeatability.

[0023] 3. This invention completes the folding and pressing of lithium batteries in one step under the drive of a dual-stroke folding and pressing drive component by embedding a heating element in the folding and pressing part. It has high heat conduction efficiency, rapid heating, and convenient and precise control of heating temperature. The temperature can be dynamically adjusted according to different processing stages or aluminum-plastic film materials, making it highly adaptable. At the same time, the aluminum-plastic film can be preheated simultaneously during the folding process to improve the folding effect and make the shape of the folding and pressing part match the edge position of the aluminum-plastic film.

The following is a detailed description with reference to the accompanying drawings.

[0039] In this embodiment, the battery limiting mechanism 2 is provided with a battery mounting station for installing the battery, and the folding and heat-pressing integrated mechanism 1 is provided with at least one folding and heat-pressing component 11. The folding and heat-pressing component 11 is arranged around the battery mounting station. The folding and heat-pressing component 11 is provided with a heating part and a folding and heat-pressing part for sequentially folding and pressing the edge of the aluminum-plastic film. The heating part of the folding and heat-pressing component 11 heats the aluminum-plastic film according to preset control parameters. For example, the aluminum-plastic film is preheated when the folding and heat-pressing part folds the edge of the aluminum-plastic film, and the temperature of the aluminum-plastic film is kept at a preset heat-pressing temperature when the folding and heat-pressing part presses the aluminum-plastic film. The folding and heat-pressing part of the folding and heat-pressing component 11 is aligned with the battery mounting station and cooperates with the folding and heat-pressing integrated mechanism 1 to sequentially complete the folding and heat-pressing of the lithium battery in one go.

[0040] In this embodiment, by integrating the folding and hot-pressing processes into a single mechanism, the folding and hot-pressing of lithium batteries can be completed in one go. This reduces the time spent transferring and waiting batteries between different workstations, avoids secondary positioning, and prevents repeated alignment errors, thereby significantly improving battery production efficiency and folding / pressing accuracy. Simultaneously, it allows for preheating of the aluminum-plastic film during folding, reducing folding stress and preventing cracks or springback in the film. This ensures that the pressed battery folds have high structural strength and a high sealing rating. Furthermore, through the cooperation of the integrated folding / pressing mechanism 1 and the battery limiting mechanism 2, simple adaptive adjustments can be made according to actual needs, making it suitable for batteries of different specifications and thus having a wide range of applications.

[0041] Preferably, to improve the protective effect and facilitate operation, the system also includes a mounting plate 3, a protective cabinet 4, an operation panel 5, and an operation table 6. The folding and ironing mechanism 1 and the battery limiting mechanism 2 are both mounted on the mounting plate 3, which provides a reliable rigid mounting base to prevent vibration of the mechanisms. The protective cabinet 4 is mounted on the mounting plate 3 and covers the folding and ironing mechanism 1 and the battery limiting mechanism 2, effectively preventing foreign objects from entering the workspace or operators from accidentally touching the moving parts. The front of the protective cabinet 4 has an operation window 41 that exposes the battery mounting position of the battery limiting mechanism 2 to the outside. The operation panel 5 is mounted on the top front of the protective cabinet 4 and is connected to the folding and ironing mechanism 1 and the battery limiting mechanism 2. The main body mechanism 1 and the battery limiting mechanism 2 are electrically connected to drive the folding and ironing mechanism 1 and the battery limiting mechanism 2 to work according to preset control parameters. The operating table 6 is installed on the mounting plate 3 and is located near the operating window 41. The operating panel 5 is provided with an indicator 51 for displaying the working status of the folding and ironing mechanism 1 and the battery limiting mechanism 2. Both the operating panel 5 and the operating table 6 are provided with control buttons 52 for controlling the operation of the folding and ironing mechanism 1 and the battery limiting mechanism 2. During operation, the operator can control the folding and ironing machine through the operating panel 5 and the operating table 6. It can adapt to different operating habits and facilitates the operator to monitor the working status of the folding and ironing machine in real time according to the indicator 51, which is convenient for monitoring.

[0042] Preferably, the battery limiting mechanism 2 includes a limiting mounting frame 21, an upper mounting plate 22, a lower mounting plate 23, an upper mounting drive device 24, and a lower mounting drive device 25. The upper mounting plate 22 and the lower mounting plate 23 are arranged vertically and alternately inside the limiting mounting frame 21 and are respectively connected to the upper mounting drive device 24 and the lower mounting drive device 25. The upper mounting plate 22 and the lower mounting plate 23 cooperate with each other under the drive of the upper mounting drive device 24 and the lower mounting drive device 25 to form a battery mounting station for installing batteries. During operation, the size of the upper mounting plate 22 and the lower mounting plate 23 is adjustable, which facilitates the replacement of the corresponding upper mounting plate 22 and the lower mounting plate 23 according to different battery specifications. The adjustment is convenient and the versatility is good. Furthermore, by controlling the driving force of the upper mounting drive device 24 and the lower mounting drive device 25, the battery can be shaped while being firmly clamped, which can further improve product quality.

[0043] In this embodiment, the lifting upper mounting plate 22 and lower mounting plate 23 work in conjunction with the folding and pressing integrated mechanism 1 to complete the folding and pressing of the lithium battery in sequence in one go. The distance between the upper mounting plate 22 and lower mounting plate 23 is adjustable, which can clamp lithium batteries of different thicknesses. It has strong versatility and makes it easy to change the position of the battery installation station according to actual needs. At the same time, the lifting upper mounting plate 22 and lower mounting plate 23 also make the space for battery insertion and removal larger, and together with the operation window 41, it facilitates semi-automatic operation.

[0044] Example 2:

[0045] Please see Figures 1 to 7 This embodiment provides a novel universal lithium battery semi-automatic aluminum-plastic film folding and ironing machine. The similarities with other embodiments will not be repeated here. The differences will be described in detail below.

[0046] In this embodiment, the folding and ironing integrated mechanism 1 further includes a folding and ironing fixing frame 12, a folding and ironing sliding frame 13, and a dual-stroke folding and ironing drive assembly 14. The folding and ironing fixing frame 12 is arranged around the battery installation station and extends towards the battery installation station. The folding and ironing sliding frame 13 is slidably and limitedly mounted on the folding and ironing fixing frame 12 along the extension direction of the folding and ironing fixing frame 12. The folding and ironing assembly 11 is connected to the output part of the dual-stroke folding and ironing drive assembly 14 through a transmission assembly and is mounted on the folding and ironing fixing frame 12 through the dual-stroke folding and ironing drive assembly 14.

[0047] In this embodiment, the dual-stroke folding and pressing drive assembly 14 drives the two different working strokes of folding and pressing respectively, which can achieve precise sequence control. At the same time, the folding and pressing sliding frame 13 can be adjusted along the folding and pressing fixed frame 12, which makes it convenient to adjust the relative position of the folding and pressing assembly 11 and the battery installation station according to actual needs. It can be applied to batteries of different specifications, with high transmission accuracy and high action repeatability.

[0048] In practical implementation, the folding and pressing assembly 11 includes a folding and pressing bracket 111, a folding and pressing section 112, and a heating assembly. The folding and pressing section 112 extends along the edge of the aluminum-plastic film and is connected to the output section of the dual-stroke folding and pressing drive assembly 14 via the folding and pressing bracket 111. The heating section of the heating assembly is embedded inside the folding and pressing section 112, and its temperature is dynamically adjusted according to preset control parameters when the folding and pressing section 112 performs the folding and pressing of the lithium battery. The folding and pressing section 112 operates under the drive of the dual-stroke folding and pressing drive assembly 14 to complete the folding and pressing of the lithium battery in sequence in one go. Preferably, the folding and ironing assembly 11 also includes a heat insulation assembly 113. The heat insulation assembly 113 is arranged around the folding and ironing part 112. The folding and ironing part 112 is mounted on the folding and ironing bracket 111 through the heat insulation assembly 113. The heat insulation assembly 113 has an opening on the side near the battery installation station for the folding and ironing part 112 to be exposed to the outside. During operation, the shape, size and position of the opening are adjustable, which facilitates different folding and ironing processes, has a high degree of customization, a wide range of applications, and can reduce heat loss to non-working areas, reduce energy consumption and prevent high temperature burns to operators or damage to batteries and surrounding components.

[0049] In this embodiment, the folding and pressing of the lithium battery is completed in one go by the folding and pressing part 112, which is equipped with a heating component, driven by the dual-stroke folding and pressing drive component 14. It has high heat conduction efficiency, fast heating, and convenient precise control of heating temperature. The temperature can be dynamically adjusted according to different processing stages or aluminum-plastic film materials, making it highly adaptable. At the same time, the aluminum-plastic film can be preheated simultaneously during the folding process to improve the folding effect and make the shape of the folding and pressing part 112 match the edge position of the aluminum-plastic film. This ensures the continuity and fit of the folding and pressing work. The heat insulation component 113 can accurately control the contact area between the folding and pressing part 112 and the battery, avoid overheating the battery, improve the quality of the finished product, and help to adjust and maintain the preset pressing temperature of the folding and pressing part 112, thereby improving process stability.

[0050] In specific implementation, the dual-stroke folding and ironing drive assembly 14 includes a first folding and ironing drive device 141, a fixed reinforcing plate 142, and a second folding and ironing drive device 143. The first folding and ironing drive device 141 is installed on the top of the folding and ironing sliding frame 13, and the second folding and ironing drive device 143 is installed on the output part of the first folding and ironing drive device 141 through the fixed reinforcing plate 142. The output part of the second folding and ironing drive device 143 is connected to the folding and ironing assembly 11 in a transmission manner. The first folding and ironing drive device 141 and the second folding and ironing drive device 143 operate according to preset control parameters to drive the folding and ironing part 112 to complete the folding and ironing work of the lithium battery in sequence. During operation, the speed, position, and pressure of the two strokes can be flexibly adjusted through preset control parameters, which is convenient for adjusting the folding depth and ironing pressure for different battery models. It can adapt to aluminum-plastic films of different thicknesses or materials, and at the same time, it can ensure that the folding pressure and ironing pressure are stable and uniform, thereby improving the folding effect and ironing effect.

[0051] Preferably, the folding and pressing integrated mechanism 1 further includes a correction component 15 for correcting the position of the lithium battery before performing the lithium battery folding and pressing work. The correction component 15 is mounted on the folding and pressing sliding frame 13 and is connected to the battery drive on the battery limiting mechanism 2 before performing the lithium battery folding and pressing work to drive the battery to move into the battery mounting station. In a specific implementation, the correction component 15 includes a correction guide rail 151, a correction slide 152, a correction part 153, and a correction drive device 154. The correction guide rail 151 is mounted on the folding and pressing sliding frame 13 and extends along the direction close to the battery mounting station. The correction part 153 corrects the position of the lithium battery by adjusting the position of the battery. The slide block 152 is slidably and limitedly mounted on the calibration guide rail 151 and is connected to the output part of the calibration drive device 154 through the transmission component. Before the lithium battery folding and hot pressing work is carried out, the calibration part 153 is connected to the battery on the battery limiting mechanism 2 under the drive of the calibration drive device 154 according to the corresponding control command, and drives the battery to move into the battery installation position. During operation, the calibration part 153 of different shapes and materials can be selected according to actual needs. For example, the calibration part 153 can be made of flexible material to avoid damaging the battery surface. Of course, the calibration part 153 with a matching shape can also be selected as needed.

[0052] When this embodiment is in operation, it can eliminate the positional deviation caused by manual feeding or previous processes, ensuring that the folding and pressing component 11 always acts on the correct edge of the aluminum-plastic film, thereby avoiding defects such as uneven folding and misaligned pressing caused by battery misalignment, reducing scrap rate, and also reducing the labor intensity of operators, reducing manual intervention, and improving production efficiency.

[0053] As a further improvement of this embodiment, the folding and ironing integrated mechanism 1 also includes a guide component 16. The guide component 16 is installed on the folding and ironing component 11, and the folding and ironing component 11 abuts against the corresponding guide base through the guide component 16. In this embodiment, the guide component 16 includes at least two guide connecting rods 161 and at least two guide rollers 162. The top of the guide connecting rod 161 is connected to the folding and ironing bracket 111, and the bottom of the guide connecting rod 161 is rolledly connected to the top surface of the mounting plate 3 through the guide rollers 162. During operation, the movement direction of the folding and ironing component 11 can be constrained to prevent the folding and ironing component 11 from falling or shifting due to lateral force or wear, ensuring that the folding and ironing part 112 is precisely aligned with the edge of the aluminum-plastic film. The rolling guide can reduce friction and extend the service life of the equipment. It can still maintain the repeatability of the folding and ironing position during long-term operation, making it suitable for mass production.

[0054] The beneficial technical effects of this embodiment include: By integrating the folding and hot pressing processes into the same mechanism, the present invention can complete the folding and hot pressing of lithium batteries in one go, reducing the time spent transferring and waiting batteries between different workstations, avoiding secondary positioning, and preventing repeated alignment errors, thereby significantly improving battery production efficiency and folding and hot pressing accuracy. At the same time, it can also preheat the aluminum-plastic film during folding, which can reduce folding stress, prevent cracks or springback of the aluminum-plastic film, and ensure that the folded battery edge has high structural strength and sealing level after hot pressing. Through the cooperation between the integrated folding and hot pressing mechanism and the battery limiting mechanism, it can be easily adapted to different battery specifications according to actual needs, and has a wide range of applications.
