Description

Technical Field

[0001] This utility model belongs to the field of battery rich liquefaction formation technology, specifically relating to a multi-form industrial battery rich liquefaction formation process acid absorption device. Background Technology

[0002] Electrolyte is a crucial component of a battery, playing a vital role in ion transport and current conduction between the positive and negative electrodes, and is essential for battery performance and lifespan. Currently, most industrial batteries employ a rich electrolyte formation process, which involves injecting an excess of electrolyte into the battery. After formation is complete, the excess electrolyte is removed, improving the formation effect and extending battery life.

[0003] Traditional methods involve using a syringe to extract acid from the battery, which is cumbersome, inefficient, and the amount of acid extracted is affected by the manual operation, resulting in deviations in the remaining electrolyte capacity in different cells. This leads to inconsistent voltage across individual cells and affects battery lifespan.

[0004] Therefore, how to provide a multi-form industrial battery rich-liquidation acid absorption device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a multi-form industrial battery rich liquefaction formation process acid absorption device, which can select the appropriate use mode according to different use needs, and has high acid absorption consistency.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a multi-form industrial battery rich-liquid formation process acid absorption device, comprising:

[0007] A negative pressure suction and storage component, which can be in a fixed or mobile form, is used to create a negative pressure environment and store the extracted electrolyte.

[0008] The liquid suction assembly is connected to the negative pressure suction and storage assembly by a vacuum pipeline. The liquid suction assembly has a manual hand-held operation mode and an automatic control mode. Multiple liquid suction heads are arranged side by side on the liquid suction assembly, and the multiple liquid suction heads simultaneously extend into the battery injection hole to synchronously draw electrolyte.

[0009] An automated transport mechanism is arranged below the suction head and completes the battery transport, start-up, and shutdown process.

[0010] The beneficial technical effects of this utility model are as follows: The negative pressure suction and storage component is used to create a negative pressure environment, which can draw out the electrolyte in the battery. In addition, the drawn-out electrolyte can be temporarily stored and collected. The liquid suction component is the execution end of acid suction. During acid suction, since multiple liquid suction heads are inserted into the battery injection hole at the same time to synchronously draw out the electrolyte, the consistency of acid suction is improved, thereby ensuring that the remaining electrolyte capacity in each cell of the battery is consistent. It can be understood that the liquid suction component of this utility model has multiple modes depending on the application. It can be a simple manual hand-held liquid suction, or it can be a mechanized liquid suction in conjunction with an automated production line. The automated transport mechanism can transport the battery, and after completing the liquid suction operation, it can be transported to the next process, thereby improving the overall liquid suction efficiency.

[0011] Preferably, the negative pressure suction storage assembly includes a vacuum pump, a vacuum cylinder, and a drainage tube assembly. The suction port of the vacuum pump is connected and communicates with the top air outlet of the vacuum cylinder. The top of the vacuum cylinder is provided with an acid suction port, which is connected to the liquid outlet of the drainage tube assembly. The liquid inlet of the drainage tube assembly is quickly connected to the liquid suction assembly.

[0012] The resulting technical effect is that the vacuum pump is the source of negative pressure, the vacuum cylinder is used to temporarily store the extracted acid, and in practice, the drainage pipe group is not a single pipe, but a radial arrangement of multiple pipes in the workshop or factory, which can effectively support the use of multiple operating stations.

[0013] Preferably, the vacuum pump and vacuum cylinder are arranged on the factory floor in a fixed manner, or the vacuum pump and vacuum cylinder are installed on a mobile trolley in a mobile manner.

[0014] The resulting technical effect is that when the vacuum pump and vacuum cylinder are arranged on the factory floor, the negative pressure suction and storage component is fixed, which can effectively support large-scale acid suction operations. When the vacuum pump and vacuum cylinder are arranged on a mobile trolley, this configuration is suitable for small-scale production, is easy to use, is not limited by the site, can be reused, and is easy for workers to operate when combined with the handheld liquid suction component.

[0015] Preferably, the liquid aspiration assembly includes a collection tube, a diversion tube, a liquid aspiration frame, and a liquid aspiration head. Multiple diversion tubes are connected in parallel to the collection tube. The collection tube is quickly connected to the inlet end of the drainage tube assembly and collects the acid in the diversion tubes into the drainage tube assembly. Multiple liquid aspiration heads are provided to match the number of battery acid injection holes. The liquid aspiration frame has slots for mounting the liquid aspiration heads. The liquid aspiration heads are mounted in adjustable positions on the slots and connected to the multiple diversion tubes. The spacing between the multiple liquid aspiration heads corresponds to the spacing between the battery acid injection holes.

[0016] The resulting technical effect is that the collecting pipe can collect the acid in the diversion pipe. It can be understood that multiple collecting pipes are connected to the drainage pipe group, which makes it possible to perform liquid suction operation at multiple workstations and can also better realize the workstation layout in the factory. The diversion pipes are arranged in groups. The grouped suction heads and the grouped diversion pipes are used in conjunction with the suction rack to complete the acid suction process of the battery acid injection hole. It should be noted that due to different battery models, the number and arrangement of battery acid injection holes are also different. At this time, it is necessary to adjust the position of the suction head to match the layout of the battery acid injection hole.

[0017] Preferably, the suction frame is a door-shaped frame structure. Bolt hole seats are provided on the two outer sides of the bottom of the suction frame. The bolt hole seats are provided with waist-shaped bolt holes. At least one support positioning plate for installing suction heads is bolted to the bottom of the suction frame. The support positioning plate is provided with an elongated slot. The length direction of the slot is perpendicular to the length direction of the waist-shaped bolt holes. Multiple suction heads are installed in the slot at adjustable intervals.

[0018] The resulting technical effect is that the position of the support positioning plate can be adjusted appropriately using the waist-shaped bolt holes. When multiple support positioning plates are installed, the spacing between the multiple support positioning plates can also be adjusted to match the positional relationship of the multiple rows of acid injection holes in the battery.

[0019] Preferably, the suction cup is available in both handheld and automatically controlled versions. When manually operated, the suction cup has C-shaped handles on one or both sides for easy gripping, and multiple through holes for limiting the flow diversion tube on its top. When controlled by a control console, a telescopic cylinder is fixedly connected to the top of the suction cup, guide rods are provided on both sides of the top, a support plate is provided on the control console, multiple guide sleeves for sliding connection of the guide rods are provided on the support plate, and a through hole for an adjustment screw is provided on the support plate. An adjustment nut is threaded onto the adjustment screw and is located on the top surface of the support plate. The bottom end of the adjustment screw is fixedly connected to the free end of the telescopic cylinder. A data scale is fixed on the support plate, and the adjustment screw adjusts the initial position height of the suction cup with reference to the data scale. The automated transport mechanism is arranged below the suction cup.

[0020] The resulting technical advantages are: the handheld suction cup has a C-shaped handle, making it easy for staff to grip and use; when the suction cup is used with a control console, the suction cup is raised and lowered by a telescopic cylinder, and the adjustable screw can be adjusted to the initial raising and lowering position of the suction cup according to different battery models, with the adjustment made by referring to the data scale, making it convenient to use.

[0021] Preferably, the suction head is a tube that runs vertically through the body. From top to bottom, the suction head includes an insertion tube section, a positioning platform section, a suction extension tube adapter section, and a suction extension tube. The insertion tube section is connected to the end of the diversion tube. The insertion tube section has an external thread near the positioning platform section, and a locking nut is connected to the external thread. The insertion tube section is located in the slot of the support positioning plate. The locking nut cooperates with the positioning platform section to fix the suction head on the support positioning plate. The suction extension tube adapter section has an internal thread, and the suction extension tube has a threaded thread that matches the internal thread. The bottom end of the suction extension tube has a conical chamfer.

[0022] The resulting technical effect is as follows: the suction head is the terminal component used to draw acid. The locking nut on the suction head and the positioning platform section cooperate to achieve a fixed connection with the support positioning plate. It should be noted that the outer side of the positioning platform section is a hexagonal shape that is easy to turn with a wrench. The suction extension tube is detachably connected to the suction extension tube adapter section. A suitable suction extension tube can be replaced as needed. The conical chamfer on the suction extension tube facilitates entry into the battery acid filling hole. In addition, the conical chamfer can prevent puncturing the separator at the top of the electrode group. After the separator is soaked in acid, it is similar to wet toilet paper and is easily broken. When it is punctured or stabbed by a sharp object, the separator can be easily penetrated, causing a short circuit between the positive and negative electrode plates.

[0023] Preferably, the automated conveying mechanism includes a conveying frame, a transmission roller assembly, a lifting and weighing component, and a positioning fixture. The transmission roller assembly is rotatably connected to the conveying frame and forms a conveying roller track. The conveying roller track is used to connect to the automated production line and has a roller track gap. The lifting and weighing component is arranged at the bottom of the conveying frame and corresponds to the bottom of the liquid suction component. The lifting and weighing component is provided with a lifting frame for passing through the roller track gap and supporting the weighing of the battery. The positioning fixture is installed on one side of the conveying frame in an adjustable position relative to the width direction of the conveying frame. The positioning fixture is provided with a guide plate. The end edge of the positioning fixture is provided with a sensing sensor and a telescopic rod. The sensing sensor is used to detect the conveying position of the battery on the conveying roller track. The extension of the telescopic rod cooperates with the guide plate to limit the stopping position of the battery on the conveying roller track. At the stopping position, the liquid suction component completes liquid suction. The side of the conveying frame away from the positioning fixture is provided with an adjustment plate to guide the battery to the guide plate.

[0024] The resulting technical effect is as follows: the drive roller assembly is rotatably connected to the conveyor frame, forming a conveyor roller track. It is understood that there are gaps between adjacent rollers on the conveyor roller track. The lifting and weighing assembly is located below the conveyor roller track; it rises during use to lift the battery and complete the weighing process, and lowers and hides below the drive roller assembly when not in use, thus not affecting the battery's movement. The positioning fixture positions the battery at the acid absorption point; it stops the battery on the conveyor roller track, and the stopping position corresponds precisely to the working position of the liquid absorption assembly. After the liquid absorption is completed, the telescopic rod releases the restriction on the battery's continued forward movement.

[0025] Preferably, the lifting and weighing assembly includes a fixed platform, a lifting cylinder, and an electronic scale. The fixed platform is fixed to the bottom of the conveyor frame, the lifting cylinder is vertically fixed to the fixed platform, the electronic scale is located at the top of the lifting cylinder and connected to the free end of the lifting cylinder, multiple sets of guide members are provided between the electronic scale and the fixed platform, a lifting frame is installed on the top of the electronic scale, and multiple sets of upright plates are spaced apart on the lifting frame.

[0026] The resulting technical effect is that the lifting cylinder in the lifting and weighing assembly can drive the electronic scale to rise and fall, thereby causing the lifting frame on the electronic scale to extend out of the conveyor roller to lift the battery. During this process, the weight of the battery can be detected to check whether it meets the requirements for liquid extraction.

[0027] It should be noted that an automated production line is a system control process, which requires a control system to control the negative pressure suction and storage components, automated conveying mechanisms, and related parts.

[0028] This utility model's acid absorption operation can be performed manually or automatically, depending on usage and environmental requirements. It is not limited to one mode. Whether in manual or automatic mode, it can ensure the consistency of acid absorption in multiple battery cells, resulting in high work efficiency and long battery life. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] See appendix to this utility model Figures 1 to 6 According to an embodiment of the present invention, a multi-form industrial battery acid absorption device for rich liquefaction formation process includes:

[0038] Negative pressure suction storage component 1, which can be in a fixed or mobile form, is used to create a negative pressure environment and store the extracted electrolyte.

[0039] The liquid absorption component 2 is connected to the negative pressure suction and storage component 1 by a vacuum pipeline. The liquid absorption component 2 has a manual hand operation mode and an automatic control mode. Multiple liquid absorption heads 24 are arranged side by side on the liquid absorption component 2. Multiple liquid absorption heads 24 are simultaneously inserted into the battery injection hole to synchronously absorb electrolyte, thereby improving the consistency of the remaining electrolyte in the battery.

[0040] The automated transport mechanism 3 is located below the liquid suction head 24 and completes the start-up and shutdown process of the battery 4.

[0041] It should be noted that the automated transport mechanism needs to be used in conjunction with a control system. Understandably, the control system can connect the negative pressure suction and storage components and the automated transport mechanism to complete the automated acid suction work.

[0042] In other embodiments, the negative pressure suction storage component 1 includes a vacuum pump 11, a vacuum cylinder 12, and a drainage tube assembly 13. The vacuum pump is the source of negative pressure. The suction port of the vacuum pump 11 is connected to and communicates with the top air outlet of the vacuum cylinder 12. The top of the vacuum cylinder 12 is provided with an acid suction port. When suctioning liquid, the acid liquid enters the vacuum cylinder from the acid suction port. The vacuum cylinder plays the role of temporarily storing the acid liquid. The acid suction port is connected to the liquid outlet of the drainage tube assembly 13. The liquid inlet of the drainage tube assembly 13 is quickly connected to the suction component 2. It can be connected by plugging and unplugging the pipeline plug or quick connector. Specifically, there is a ball valve switch on the branch of the vacuum pipeline. The ball valve switch controls the opening and closing of the pipeline to facilitate the installation of local components without affecting the overall working process.

[0043] In other embodiments, the vacuum pump 11 and vacuum cylinder 12 are arranged on the factory floor in a fixed configuration, or the vacuum pump 11 and vacuum cylinder 12 are mounted on a mobile trolley 14 in a mobile configuration. The mobile configuration is suitable for small-scale, simple operation, especially for batteries that are not easy to automate.

[0044] The mobile trolley includes casters, a trolley platform, and a push handle. The casters are located at the four corners of the bottom of the trolley platform, and the push handle is located on one side of the trolley platform and is fixedly welded to the trolley platform to facilitate pushing the trolley forward or backward. The vacuum pump is located on the top surface of the trolley platform near the trolley handle, and the vacuum cylinder is located on the other side.

[0045] In some other specific embodiments, the liquid aspiration assembly 2 includes a collection tube 21, a diversion tube 22, a liquid aspiration frame 23, and a liquid aspiration head 24. There are multiple diversion tubes 22 connected in parallel to the collection tube 21. The collection tube 21 is quickly connected to the inlet end of the drainage tube group 13 and collects the acid in the diversion tube into the drainage tube group. There are multiple sets of liquid aspiration heads 24 that match the number of battery acid injection holes. The liquid aspiration frame 23 has slots for installing liquid aspiration heads. The liquid aspiration heads 24 are installed in adjustable positions in the slots and are connected to the multiple diversion tubes 22. The spacing between the multiple liquid aspiration heads 24 corresponds to the spacing between the battery acid injection holes. In specific implementation, the pipeline must be kept in a sealed state; otherwise, a negative pressure suction environment cannot be established.

[0046] In some other embodiments, the suction holder 23 is a door-shaped frame structure. Bolt hole seats are provided on the two outer sides of the bottom of the suction holder 23. The bolt hole seats have waist-shaped bolt holes, similar to long strip slots, to provide a wide adjustment space for the bolts. The bottom of the suction holder 23 is bolted to at least one support positioning plate 231 for installing the suction head. When multiple support positioning plates are installed, the spacing between the support positioning plates can be adjusted due to the waist-shaped slots. The support positioning plate 231 has long strip slots 232. The length direction of the slots 232 is perpendicular to the length direction of the waist-shaped bolt holes. Multiple suction heads 24 can be installed in the slots 232 with adjustable spacing. The distance between multiple suction heads arranged side by side can also be adjusted to match the position of the battery acid injection hole.

[0047] In some other specific embodiments, the suction cup 23 can be used in two ways: handheld and automatically controlled. When the suction cup 23 is manually operated, one or both sides of the suction cup 23 are provided with C-shaped handles 25 for easy hand holding. The top of the suction cup 23 is provided with multiple through holes for limiting the diversion tube. It should be noted that in the handheld state, the worker can directly operate the suction cup, and the requirements for automation control are low.

[0048] When the suction rack 23 is operated by the control console 5, a telescopic cylinder 52 is fixedly connected to the top of the suction rack 23, and guide rods 53 are provided on both sides of the top of the suction rack 23. A support plate 51 is provided on the control console 5, and multiple guide sleeves for sliding connection of the guide rods 53 are provided on the support plate 51 to ensure the stable lifting and lowering process of the suction rack. A through hole for the adjustment screw 54 is provided on the support plate 51, and an adjustment nut 55 is threadedly connected to the adjustment screw 54 and the adjustment nut 55 is located on the top surface of the support plate 51. The bottom end of the adjustment screw 54 is fixedly connected to the free end of the telescopic cylinder. A data scale 56 is fixed on the support plate 51. The adjustment screw 54 is adjusted with reference to the data scale 56 to adjust the initial position height of the suction rack 23. Since the height of different types of batteries is different, adjusting the initial position of the suction rack can ensure that the suction head can enter the acid hole normally. The automated transport mechanism 3 is arranged below the suction rack 23.

[0049] In some other specific embodiments, the suction head 24 is a tube that runs vertically through the body and is integrally formed from an acid-resistant material. The suction head 24 includes, from top to bottom, an insertion tube section 241, a positioning platform section 242, a suction extension tube adapter section 243, and a suction extension tube 244. The insertion tube section 241 is connected to the end of the diversion tube 22. The insertion tube section 241 is provided with an external thread near the positioning platform section 242, and a locking nut 245 is connected to the external thread. The insertion tube section 241 is located in the slot of the support positioning plate 231. The locking nut 245 cooperates with the positioning platform section 242 to fix the suction head on the support positioning plate 231. The suction extension tube adapter section 243 is provided with an internal thread, and the suction extension tube 244 is provided with a threaded thread that matches the internal thread. The bottom end of the suction extension tube 244 is provided with a conical chamfer to prevent the sharp head from piercing the partition plate above the electrode group. In addition, it also facilitates the suction head to enter the acid injection hole.

[0050] In some other embodiments, the automated conveying mechanism 3 includes a conveying frame 31, a drive roller assembly 32, a lifting and weighing component 33, and a positioning fixture 34. The drive roller assembly 32 is rotatably connected to the conveying frame 31 and forms a conveying roller track, which is used to connect to the automated production line. The conveying roller track has roller gaps. The lifting and weighing component 33 is arranged at the bottom of the conveying frame 31 and corresponds to the area below the liquid suction component 2. The lifting and weighing component 33 is provided with a lifting frame 334 for passing through the roller gap and supporting the weighing of the battery. The positioning fixture 34 is installed on one side of the conveying frame in an adjustable position relative to the width direction of the conveying frame. Since the width of different battery models is different, it can be adjusted accordingly. It is understood that the positioning fixture can be adjusted in position on the width of the conveyor rollers (there are fixing bolts on the conveyor frame, and long slots on the end body of the positioning fixture; after adjusting the position, the nuts can be tightened). The positioning fixture 34 is equipped with a guide plate 341, and the end edge of the positioning fixture 34 is equipped with a sensor 342 and a telescopic rod 343. The sensor 342 is used to detect the conveying position of the battery on the conveyor rollers. When the battery passes the sensor, the sensor senses the sensor and feeds the data back to the control system center. The control system center controls the telescopic rod to extend, so that the battery is limited to the angle formed by the guide plate and the telescopic rod.

[0051] The extension of the telescopic rod 343, in conjunction with the guide plate 341, defines the stopping position of the battery on the conveyor roller. At the stopping position, corresponding to the working position of the liquid suction component, the control center controls the telescopic cylinder to move down, so that the liquid suction component enters the acid injection hole to complete the liquid suction process. The side of the conveyor frame 31 away from the positioning fixture 34 is provided with an adjustment plate 35 to guide the battery to the guide plate 341. This allows for more precise control of the battery position, so that the battery is stopped within the angle formed by the guide plate and the telescopic rod.

[0052] In other embodiments, the lifting and weighing assembly 33 includes a fixed platform 331, a lifting cylinder 332, and an electronic scale 333. The fixed platform 331 is fixed to the bottom of the conveyor frame 31, the lifting cylinder 332 is vertically fixed on the fixed platform 331, the electronic scale 333 is located on top of the lifting cylinder 332 and connected to the free end of the lifting cylinder 332, multiple sets of guide members are provided between the electronic scale 333 and the fixed platform 331, and a lifting frame 334 is installed on the top of the electronic scale 333. Multiple sets of upright plates are provided on the lifting frame 334 at intervals. The lifting and weighing assembly needs to be linked with the control system to realize the systematic liquid suction and weighing process. The electronic scale display can accurately display the weighing value of the electronic scale.

[0053] In practical use, it includes the following steps:

[0054] Step 1: Assemble the acid suction system. Connect the negative pressure suction and storage component to the liquid suction component and ensure the negative pressure pipeline is connected. The negative pressure suction and storage component can be set to a fixed form or a mobile form with a mobile cart, depending on the use. The liquid suction component has two modes: handheld operation mode and automatic control mode, depending on the user.

[0055] Step 2: Adjust the number and position of the suction heads according to different battery models. The suction heads are installed on the suction rack, which has a support positioning plate for installing the suction heads. Adjust the number and position of the suction heads on the support positioning plate according to the number and position of the acid injection holes of different battery models.

[0056] Step 3: Based on Step 1 and Step 2, use in conjunction with an automated transport mechanism. The automated transport mechanism has a positioning fixture for positioning the battery liquid suction position. After the positioning fixture positions the battery to stop, the liquid suction component above the battery descends and works with the negative pressure suction storage component to complete the liquid suction process.

[0057] Step 4: Based on Step 3, activate the lifting and weighing component on the automated conveying mechanism. The lifting and weighing component rises, and the lifting frame on it passes through the conveyor rollers to lift the battery and complete the weighing. If the battery weight parameter requirements are met, control the lifting and weighing component to move down, and the lifting frame will be hidden below the conveyor rollers. The conveyor rollers will continue to transport the battery downstream. If the weighing result does not meet the battery weight parameter requirements, control the liquid suction component to continue to suck the acid inside the battery until the battery weight parameter requirements are met. The battery weighing result directly reflects the amount of liquid sucked.

[0058] Step 5: After the negative pressure suction storage component has been working for a period of time, the acid in the vacuum cylinder of the negative pressure suction storage component needs to be discharged to facilitate the subsequent battery liquid absorption process.

[0059] After the battery formation process is complete, the battery moves forward (x-axis) driven by the conveyor rollers. After passing the adjustment plate, the battery approaches the guide plate. When the battery passes the sensor, the telescopic rod extends or retracts (y-axis). After a specified delay of seconds, the conveyor rollers stop moving forward. At this point, the battery has moved to the angle between the telescopic rod and the guide plate, achieving positioning of the battery in the X and Y axes. Then, the lifting cylinder extends, and the lifting frame lifts the battery and moves it upward along the Z-axis. The lifting frame raises the battery above the plane of the conveyor rollers, and the electronic scale displays a stable battery weight. Further, the telescopic cylinder extends, causing the liquid suction component's suction frame to move downward. The liquid suction extension tube extends into the battery's acid injection hole, using vacuum negative pressure to suck up the remaining electrolyte after the rich electrolyte formation process. After the extension delay of the telescopic cylinder ends, the liquid suction rack rises to the high position, and the electronic scale stably displays the weight of the battery after liquid suction; the weight of liquid suction can be calculated by the computer program; the lifting cylinder retracts, the telescopic rod in the Y-axis direction retracts, the conveyor roller starts, the battery descends onto the conveyor roller, and continues to flow to the next process.
