Description

Technical Field

[0001] The invention belongs to the technical field of lead-acid battery enrichment forming technology, and particularly relates to a multi-form acid suction device and method for an industrial lead-acid battery enrichment forming process. Background Art

[0002] The electrolyte is one of the important components of a lead-acid battery. It plays a role in ion transportation and current conduction between the positive and negative electrodes of the battery, and is crucial for the performance and lifespan of the battery. Currently, most industrial lead-acid batteries adopt the enrichment forming process, that is, an excessive amount of electrolyte is injected into the battery. After the forming is completed, the excess electrolyte is sucked out to improve the forming effect and extend the lifespan of the battery.

[0003] The traditional method uses a syringe to suck out the acid liquid in the battery. The operation is cumbersome, the efficiency is low, and the acid suction amount is affected by the manual operation method, resulting in a deviation in the remaining electrolyte capacity in multiple cells of the battery, leading to poor consistency of the single-cell voltages of the battery and affecting the lifespan of the battery.

[0004] Therefore, how to provide a multi-form acid suction device and method for an industrial lead-acid battery enrichment forming process is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the invention provides a multi-form acid suction device for an industrial lead-acid battery enrichment forming process, which can select a suitable usage mode according to different usage needs and has high acid suction consistency.

[0006] To achieve the above object, the invention adopts the following technical scheme: A multi-form acid suction device for an industrial lead-acid battery enrichment forming process, which comprises:

[0007] A negative pressure suction and storage assembly, the negative pressure suction and storage assembly is in a fixed form or a mobile form, and the negative pressure suction and storage assembly is used to create a negative pressure environment and store the extracted electrolyte;

[0008] A liquid suction assembly, a communication vacuum pipeline is provided between the liquid suction assembly and the negative pressure suction and storage assembly. The liquid suction assembly has a manual hand-held operation mode and an automatic control mode. A plurality of liquid suction heads are arranged side by side on the liquid suction assembly, and the plurality of liquid suction heads simultaneously extend into the battery liquid injection holes to synchronously suck the electrolyte;

[0009] An automatic transportation mechanism, the automatic transportation mechanism is arranged below the liquid suction head and completes the start and stop process of the battery transportation.

[0010] The beneficial technical effect of the present invention is that the negative pressure suction storage component is used to create a negative pressure environment, and the generated negative pressure can suck the electrolyte in the battery. In addition, the sucked electrolyte can be temporarily stored and concentrated. The liquid suction component is the execution end of acid suction. When absorbing acid, since multiple liquid suction heads are simultaneously extended into the battery injection hole to synchronously absorb the electrolyte, the consistency of acid absorption 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 the present invention has multiple modes according to different users. It can be a simple manual hand-held operation to absorb liquid, or it can be a mechanized liquid suction in conjunction with an automated assembly line. The automated transportation mechanism can transport the battery over, 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 group, the suction port of the vacuum pump is connected and communicated with the top air outlet of the vacuum cylinder, the top of the vacuum cylinder is provided with an acid suction port, the acid suction port is connected to the liquid outlet end of the drainage tube group, and the liquid inlet end of the drainage tube group is quickly connected to the liquid suction assembly.

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

[0013] Preferably, the vacuum pump and the vacuum cylinder are arranged on the floor of a factory to form a fixed configuration, or the vacuum pump and the vacuum cylinder are installed on a mobile vehicle to form a mobile configuration.

[0014] The resulting technical effect is: when the vacuum pump and the vacuum cylinder are arranged on the factory floor, the negative pressure suction storage assembly is fixed, and in this state it can effectively support large-scale acid suction operations; and when the vacuum pump and the vacuum cylinder are arranged on a mobile cart, this state is adapted to small-scale production needs, is easy to use, is not restricted by the site, can be used in rotation, and is convenient for workers to operate in conjunction with a manually held liquid suction assembly.

[0015] Preferably, the liquid pipetting assembly includes a liquid collecting tube, a shunt tube, a liquid pipetting rack and a liquid pipetting head. There are multiple shunt tubes and they are connected in parallel to the liquid collecting tube. The liquid collecting tube is quickly connected to the liquid inlet end of the drainage tube group and gathers the acid in the shunt tube into the drainage tube group. There are multiple groups of liquid pipetting heads and they match the number of battery acid injection holes. The liquid pipetting rack is provided with slots for mounting the liquid pipetting heads. The liquid pipetting heads can be mounted on the slots in an adjustable position and are correspondingly connected to multiple shunt tubes. The spacing distance between the multiple liquid pipetting heads corresponds to the spacing distance between the battery acid injection holes.

[0016] The resulting technical effects are as follows: The liquid collecting pipe can converge the acid liquid in the shunt pipes. It can be understood that multiple liquid collecting pipes are connected to the drainage pipe group, making it possible to perform liquid suction operations at multiple workstations and better realizing the layout of workstations in the factory building. The shunt pipes are arranged in groups, and the liquid suction heads arranged in groups and the shunt pipes arranged in groups are used in cooperation with the liquid suction rack to complete the acid suction process of the battery acid injection holes. 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, the position of the liquid suction head needs to be adjusted to match the layout of the battery acid injection holes.

[0017] Preferably, the liquid suction rack is of a portal frame structure. Bolt hole seats are provided on the two outer sides of the bottom of the liquid suction rack, and waist-shaped bolt holes are opened in the bolt hole seats. At least one support positioning plate for installing the liquid suction head is bolted to the bottom of the liquid suction rack. A long strip-shaped slot is opened in the support positioning plate, and the length direction of the slot is perpendicular to the length direction of the waist-shaped bolt hole. Multiple liquid suction heads are installed in the slot at adjustable interval positions.

[0018] The resulting technical effects are as follows: The position of the support positioning plate can be appropriately adjusted by using the waist-shaped bolt holes. When multiple support positioning plates are installed, the distance between the multiple support positioning plates can also be adjusted, so as to match the positional relationship of the multi-row acid injection holes of the battery.

[0019] Preferably, there are two types of the liquid suction rack in use: handheld type and automatic control type. When the liquid suction rack is held and operated manually, C-shaped handles for easy holding are provided on one side or both sides of the liquid suction rack, and multiple through holes for limiting the shunt pipes are provided on the top of the liquid suction rack. When the liquid suction rack is controlled and operated by a control console, a telescopic cylinder is fixedly connected to the top of the liquid suction rack, and guide rods are provided on both sides of the top of the liquid suction rack. A support plate is provided on the control console, and multiple guide sleeves for slidably connecting the guide rods are provided on the support plate. A perforation for avoiding the position adjustment screw is provided on the support plate. An adjustment screw is threadedly connected with an adjustment nut, and the adjustment nut 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 liquid suction rack with reference to the data scale. The automatic transportation mechanism is arranged below the liquid suction rack.

[0020] The resulting technical effects are as follows: The handheld liquid suction rack is provided with C-shaped handles, which is convenient for the staff to hold and use. When the liquid suction rack is used in combination with a control console, the liquid suction rack is lifted and lowered by the telescopic cylinder. The set adjustment screw can adjust the initial lifting position of the liquid suction rack according to different battery models, and it is adjusted with reference to the data scale, which is convenient to use.

[0021] Preferably, the liquid suction head is a tube body that is penetrated up and down. The liquid suction head successively includes an insertion tube section, a positioning table section, a liquid suction extension tube adapter section, and a liquid suction extension tube from top to bottom. The insertion tube section is connected to the end of the shunt tube. The insertion tube section is provided with an external thread near the positioning table section, and a locking nut is connected to the external thread. The insertion tube section is located in the slot hole of the support positioning plate. The locking nut cooperates with the positioning table section to fix the liquid suction head on the support positioning plate. The liquid suction extension tube adapter section is provided with an internal thread, and the liquid suction extension tube is provided with a thread thread that matches the internal thread. The bottom end of the liquid suction extension tube is provided with a conical chamfer.

[0022] The resulting technical effect is that the liquid suction head is a terminal component for sucking acid solution. The locking nut and the positioning table section on the liquid suction head cooperate to achieve its fixed connection with the support positioning plate. It should be noted that the outer side of the positioning table section is in a hexagonal shape for easy wrenching. The liquid suction extension tube is detachably connected to the liquid suction extension tube adapter section, and a suitable liquid suction extension tube can be replaced according to needs. The conical chamfer on the liquid suction extension tube facilitates entry into the battery acid injection hole. In addition, the conical chamfer can prevent piercing the separator on the upper part of the electrode group. After the separator is soaked in acid, it is similar to wet toilet paper and is easily broken. When pierced by a sharp object, the separator is easily penetrated, causing a short circuit between the positive and negative plates.

[0023] Preferably, the automatic transportation mechanism includes a transportation frame, a transmission roller group, a lifting and weighing assembly, and a positioning tooling. The transmission roller group is rotatably connected to the transportation frame and forms a conveying roller path. The conveying roller path is used to connect to the automatic production line. There is a roller path gap on the conveying roller path. The lifting and weighing assembly is arranged at the bottom of the transportation frame and corresponds to the lower part of the liquid suction assembly. The lifting and weighing assembly is provided with a lifting frame for passing through the roller path gap and supporting the battery for weighing. The positioning tooling is installed on one side of the transportation frame with an adjustable position in the width direction of the transportation frame. The positioning tooling is provided with a guide plate. The end edge of the positioning tooling is provided with an induction sensor and a telescopic rod. The induction sensor is used to detect the transportation position of the battery on the conveying roller path. The extension of the telescopic rod cooperates with the guide plate to define the stop position of the battery on the conveying roller path. At the stop position, the liquid suction assembly completes the liquid suction. An adjustment plate for guiding the battery to the guide plate is provided on the side of the transportation frame away from the positioning tooling.

[0024] The resulting technical effects are as follows: The driving roller group is rotatably connected to the transport rack to form a conveying roller path. It can be understood that there are gaps between adjacent roller shafts on the conveying roller path. The lifting and weighing assembly is located below the conveying roller path and is raised during use to lift the battery to complete the weighing process, and is lowered and hidden below the driving roller group when not in use, so as not to affect the movement of the battery. The positioning tooling is used to position the acid suction position of the battery. It can be understood that the positioning tooling stops the battery on the conveying roller path, and the stopping position exactly corresponds to the working position of the liquid suction assembly. After the liquid suction work is completed, the telescopic rod releases the restriction on the battery to continue moving forward.

[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 transport rack. The lifting cylinder is vertically fixed on the fixed platform. The electronic scale is located at the top of the lifting cylinder and is connected to the free end of the lifting cylinder. There are multiple groups of guiding members between the electronic scale and the fixed platform. A lifting frame is installed on the top of the electronic scale, and multiple groups of vertical plates are arranged at intervals on the lifting frame.

[0026] The resulting technical effects are as follows: The lifting cylinder in the lifting and weighing assembly can drive the electronic scale to lift, so that the lifting frame on the electronic scale extends out of the conveying roller path to lift the battery, and the weight detection of the battery can be completed during this process to check whether the liquid pumping requirements are met.

[0027] It should be noted that the automated production line is a process of system control, which requires the control system to control the negative pressure suction and storage assembly, the automated transport mechanism and related components.

[0028] The present invention also discloses a method for acid suction in the liquefaction process of industrial storage batteries with multiple forms, which uses the above-mentioned acid suction device and includes the following steps:

[0029] Step 1: Assemble the acid suction system, connect the negative pressure suction and storage assembly with the liquid suction assembly and ensure the connection relationship of the negative pressure pipeline. The negative pressure suction and storage assembly is set into a fixed form according to the use needs or constitutes a mobile form by supporting a mobile trolley. The liquid suction assembly has two modes: a hand-held operation mode and an automatic control mode according to different use objects;

[0030] Step 2: Adjust the number and positional relationship of the liquid suction heads according to different battery models. The liquid suction heads are installed on the liquid suction frame. There are support positioning plates for installing the liquid suction heads on the liquid suction frame. Adjust the liquid suction heads on the support positioning plates according to the number and positional relationship of the acid injection holes of different battery models so that their numbers and positional relationships match;

[0031] Step 3: Based on Steps 1 and 2, it is used in cooperation with an automated transportation mechanism. There is a positioning tooling on the automated transportation mechanism for positioning the battery liquid suction position. After the positioning tooling locates the battery stop position, the liquid suction component above the battery descends and cooperates with the negative pressure suction storage component to complete the liquid suction process;

[0032] Step 4: Based on Step 3, start the lifting and weighing component on the automated transportation mechanism. The lifting and weighing component rises, and the lifting frame on it passes through the conveying roller path and then lifts the battery to complete weighing. If the battery weight parameter requirements are met, control the lifting and weighing component to move down, and the lifting frame hides below the conveying roller path, and the conveying roller path continues to transport the battery downstream; if the weighing result does not meet the battery weight parameter requirements, control the liquid suction component to continue sucking the acid liquid inside the battery until the battery weight parameter requirements are met. The weighing result of the battery directly reflects the liquid pumping volume;

[0033] Step 5: After the negative pressure suction storage component works for a period of time, it is necessary to discharge the acid liquid in the vacuum cylinder of the negative pressure suction storage component to facilitate the subsequent battery liquid suction process.

[0034] The beneficial effects of the present invention are as follows: The acid suction operation of the present invention can have a manual operation mode and an automatic operation mode according to the use requirements and environmental requirements. The use form is not limited to one kind. Whether it is the manual operation mode or the automatic operation mode, it can ensure the consistency of multi-cell acid suction of the battery, with high working efficiency and long battery service life.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Refer to the attached Figures 1 to 6 According to an acid suction device for the liquefaction process of industrial storage batteries in multiple forms according to an embodiment of the present invention, it includes:

[0044] A negative pressure suction storage assembly 1, the negative pressure suction storage assembly 1 is in a fixed form or a mobile form, and the negative pressure suction storage assembly 1 is used to create a negative pressure environment and store the extracted electrolyte;

[0045] A liquid suction assembly 2, a vacuum pipeline is provided between the liquid suction assembly 2 and the negative pressure suction storage assembly 1. The liquid suction assembly 2 has a manual hand-held operation mode and an automatic control mode. A plurality of liquid suction heads 24 are arranged side by side on the liquid suction assembly 2, and the plurality of liquid suction heads 24 simultaneously extend into the battery liquid injection holes to synchronously suck the electrolyte, improving the consistency of the remaining electrolyte in the battery;

[0046] An automatic transport mechanism 3, the automatic transport mechanism 3 is arranged below the liquid suction head 24 and completes the start and stop process of transporting the storage battery 4.

[0047] It should be noted that the automatic transport mechanism needs to be used in conjunction with a control system. It can be understood that the control system can connect the negative pressure suction storage assembly and the automatic transport mechanism to cooperate to complete the automatic acid suction work.

[0048] In some other embodiments, the negative pressure suction storage assembly 1 includes a vacuum pump 11, a vacuum cylinder 12, and a drainage tube group 13. The vacuum pump is the source of generating negative pressure. The suction port of the vacuum pump 11 is connected and communicated with the top air outlet of the vacuum cylinder 12. An acid suction port is provided at the top of the vacuum cylinder 12. When sucking liquid, the acid liquid enters the vacuum cylinder from the acid suction port. The vacuum cylinder plays a role in temporarily storing the acid liquid. The acid suction port is connected to the liquid outlet end of the drainage tube group 13, and the liquid inlet end of the drainage tube group 13 is quickly detachably connected to the liquid suction assembly 2, and can be connected and disconnected by using a pipeline plug or a quick connector. Specifically, there is a ball valve switch on the branch of the vacuum pipeline, and the ball valve switch controls the on-off of the pipeline to facilitate the installation of local components and will not affect the overall working process.

[0049] In some other embodiments, the vacuum pump 11 and the vacuum cylinder 12 are arranged on the factory floor to form a fixed form, or the vacuum pump 11 and the vacuum cylinder 12 are installed on a mobile trolley 14 to form a mobile form. The mobile form is suitable for small-scale simple operations, for those batteries that are not convenient for automated operation.

[0050] The mobile trolley includes universal wheels, a trolley platform, and a trolley handle. The universal wheels are respectively arranged at the four corners of the bottom of the trolley platform, and the trolley handle is arranged 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 arranged on the top surface of the trolley platform near one side of the trolley handle, and the vacuum cylinder is arranged on the other side.

[0051] In some other specific embodiments, the liquid suction assembly 2 includes a liquid collecting tube 21, a shunt tube 22, a liquid suction rack 23, and a liquid suction head 24. There are multiple shunt tubes 22 and they are connected in parallel to the liquid collecting tube 21. The liquid collecting tube 21 is quickly detachably connected to the liquid inlet end of the drainage tube group 13 and converges the acid liquid in the shunt tubes into the drainage tube group. There are multiple groups of liquid suction heads 24 and they match the number of battery acid injection holes. There are slot holes for installing the liquid suction heads on the liquid suction rack 23. The liquid suction heads 24 are adjustably installed in the slot holes and are correspondingly connected to multiple shunt tubes 22. The spacing distance between multiple liquid suction heads 24 corresponds to the spacing distance of the battery acid injection holes. During specific implementation, ensure the airtight state of the pipeline, otherwise a negative pressure suction environment cannot be established.

[0052] In some other embodiments, the liquid suction rack 23 is of a portal frame structure. Bolt hole seats are provided on the two outer sides of the bottom of the liquid suction rack 23, and waist-shaped bolt holes are formed in the bolt hole seats, which are similar to long strip-shaped slot holes. The purpose is to provide a wide adjustment space for the bolts. At least one support positioning plate 231 for installing the liquid suction head is bolted to the bottom of the liquid suction rack 23. When multiple support positioning plates are installed, due to the setting of the waist-shaped slot holes, the spacing between the support positioning plates can be adjusted. A long strip-shaped slot hole 232 is formed in the support positioning plate 231. The length direction of the slot hole 232 is perpendicular to the length direction of the waist-shaped bolt hole. Multiple liquid suction heads 24 can be installed in the slot hole 232 at adjustable interval positions, and the distance between the multiple side-by-side liquid suction heads can also be adjusted to match the positions of the battery acid injection holes.

[0053] In some other specific embodiments, there are two types of operations for the liquid suction rack 23: handheld and automatic control. When the liquid suction rack 23 is held and operated manually, C-shaped handles 25 for easy handholding are provided on one side or both sides of the liquid suction rack 23. A plurality of through holes for limiting the flow dividing pipe are provided at the top of the liquid suction rack 23. It should be noted that in the handheld state, workers can directly operate the liquid suction rack, and the requirement for automatic control is relatively low.

[0054] When the liquid suction rack 23 is controlled and operated by the control console 5, a telescopic cylinder 52 is fixedly connected to the top of the liquid suction rack 23. Guide rods 53 are provided on both sides of the top of the liquid suction rack 23. A support plate 51 is provided on the control console 5, and a plurality of guide sleeves for slidably connecting the guide rods 53 are provided on the support plate 51, so as to ensure the stable lifting process of the liquid suction rack. A perforation for avoiding the position adjustment screw rod 54 is provided on the support plate 51. An adjustment nut 55 is threadedly connected to the adjustment screw rod 54 and the adjustment nut 55 is located on the top surface of the support plate 51. The bottom end of the adjustment screw rod 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 rod 54 adjusts the initial position height of the liquid suction rack 23 with reference to the data scale 56. Since the heights of different types of batteries are different, adjusting the initial position of the liquid suction rack can ensure that the liquid suction head can normally enter the acid hole. The automatic transportation mechanism 3 is arranged below the liquid suction rack 23.

[0055] In some other specific embodiments, the liquid suction head 24 is a tube body that penetrates up and down. It is integrally formed of acid-resistant material. The liquid suction head 24 successively includes an insertion tube section 241, a positioning table section 242, a liquid suction extension tube adapter section 243, and a liquid suction extension tube 244 from top to bottom. The insertion tube section 241 is connected to the end of the shunt tube 22. An external thread is provided on the insertion tube section 241 near the positioning table 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 table section 242 to fix the liquid suction head on the support positioning plate 231. An internal thread is provided on the liquid suction extension tube adapter section 243, and a thread thread matching the internal thread is provided on the liquid suction extension tube 244. A conical chamfer is provided at the bottom end of the liquid suction extension tube 244, which can prevent the sharp head from piercing the separator on the upper part of the electrode group. In addition, it is also convenient for the liquid suction head to enter the acid injection hole.

[0056] In some other embodiments, the automatic transportation mechanism 3 includes a transportation frame 31, a transmission roller group 32, a lifting and weighing assembly 33, and a positioning tooling 34. The transmission roller group 32 is rotatably connected to the transportation frame 31 and forms a conveying roller path. The conveying roller path is used to connect to the automatic production line. There is a roller path gap on the conveying roller path. The lifting and weighing assembly 33 is arranged at the bottom of the transportation frame 31 and corresponds to the lower part of the liquid suction assembly 2. A lifting frame 334 for passing through the roller path gap and supporting the battery for weighing is provided on the lifting and weighing assembly 33. The positioning tooling 34 is installed on one side of the transportation frame with an adjustable position relative to the width direction of the transportation frame. Since the widths of different models of batteries are different, it can be understood that the positioning tooling can adjust the installation position on the width of the conveying roller path (there are fixing bolts on the transportation frame, and there are long slot holes on the end body of the positioning tooling. After adjusting the position, the locking nut can be tightened). A guide plate 341 is provided on the positioning tooling 34. An induction sensor 342 and a telescopic rod 343 are provided at the edge of the end of the positioning tooling 34. The induction sensor 342 is used to detect the transportation position of the battery on the conveying roller path. When the battery passes by the induction sensor, the induction sensor feeds back the data to the control system center after sensing the sensor. The control system center controls the telescopic rod to extend, so that the battery is limited within the included angle formed by the guide plate and the telescopic rod;

[0057] The extension of the telescopic rod 343 cooperates with the guide plate 341 to define the stop position of the battery on the conveying roller path. When the battery is at the stop position, corresponding to the working position of the liquid suction assembly, the control center controls the telescopic cylinder to move down, so that the liquid suction assembly enters the acid injection hole to complete the liquid suction process. An adjustment plate 35 for guiding the battery to the guide plate 341 is provided on the side of the transportation frame 31 away from the positioning tooling 34. In this way, the position of the battery can be controlled more precisely, so that the battery is intercepted within the included angle formed by the guide plate and the telescopic rod.

[0058] In some 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 transport rack 31. The lifting cylinder 332 is vertically fixed on the fixed platform 331. The electronic scale 333 is located at the top of the lifting cylinder 332 and connected to the free end of the lifting cylinder 332. A plurality of groups of guiding members are provided between the electronic scale 333 and the fixed platform 331. A lifting frame 334 is installed on the top of the electronic scale 333. A plurality of groups of vertical plates are arranged at intervals on the lifting frame 334. 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.

[0059] The present invention also discloses a method for sucking acid in the liquefaction process of an industrial battery with multiple forms, which uses the above-mentioned acid sucking device and includes the following steps:

[0060] Step 1: Assemble the acid sucking system, connect the negative pressure suction storage component and the liquid suction component and ensure the connection relationship of the negative pressure pipeline. The negative pressure suction storage component is set into a fixed form according to the use needs or constitutes a mobile form with a supporting mobile trolley. The liquid suction component has two modes: a handheld operation mode and an automatic control mode according to different use objects;

[0061] Step 2: Adjust the number and positional relationship of the liquid suction heads according to different battery models. The liquid suction heads are installed on the liquid suction rack. There are supporting positioning plates for installing the liquid suction heads on the liquid suction rack. Adjust the liquid suction heads on the supporting positioning plates according to the number and positional relationship of the acid injection holes of different battery models and make their numbers and positional relationships match;

[0062] Step 3: Based on Steps 1 and 2, use it in cooperation with the automatic transport mechanism. There is a positioning tooling for positioning the battery liquid suction position on the automatic transport mechanism. After the positioning tooling positions the stopping position of the battery, the liquid suction component above the battery descends and cooperates with the negative pressure suction storage component to complete the liquid suction process;

[0063] Step 4: Based on Step 3, start the lifting and weighing assembly on the automatic transport mechanism. The lifting and weighing assembly rises, and the lifting frame on it passes through the conveying roller path and then lifts the battery and completes the weighing. If the battery weight parameter requirements are met, control the lifting and weighing assembly to move down, and the lifting frame hides under the conveying roller path, and the conveying roller path continues to transport the battery downstream; if the weighing result does not meet the battery weight parameter requirements, control the liquid suction component to continue sucking the acid liquid inside the battery until the battery weight parameter requirements are met. The weighing result of the battery directly reflects the liquid pumping volume;

[0064] Step 5: After the negative pressure suction storage component works for a period of time, it is necessary to discharge the acid liquid in the vacuum cylinder of the negative pressure suction storage component to facilitate the subsequent battery liquid suction process.

[0065] After the formation of the storage battery is completed, the battery moves forward (x-axis) driven by the conveying roller path. After passing through the adjustment plate, the battery approaches one side of the guide plate. When the battery passes through the induction sensor, the telescopic rod expands and contracts (y-axis). After a specified delay in seconds, the conveying roller path stops moving forward. At this time, the storage battery travels to the angle between the telescopic rod and the guide plate, achieving the positioning of the storage battery in the x-axis and y-axis directions. At this time, the lifting cylinder extends, and the lifting bracket lifts the storage battery and moves upward along the z-axis. The lifting bracket lifts the storage battery above the plane of the conveying roller path, and the electronic scale display stably shows the weight of the battery. Further, the telescopic cylinder extends, causing the liquid suction frame of the liquid suction assembly to move downward, and the liquid suction extension tube extends into the acid injection hole of the storage battery to suck the remaining electrolyte after the formation of the rich liquid using vacuum negative pressure. After the extension of the telescopic cylinder ends, the liquid suction frame rises to the high position, and the electronic scale stably shows the weight of the battery after liquid extraction; the weight of the liquid extraction can be calculated through the computer program; the lifting cylinder contracts, the telescopic rod in the y-axis direction contracts, the conveying roller path starts, and the storage battery descends onto the conveying roller path and continues to flow to the next process.
