Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 4, the liquid injection device 10 of the preferred embodiment of the present invention includes a bottom plate 100, a platform 200, a liquid injection chamber 300, a residual liquid collecting assembly 400 and a lifting assembly 500.
The base plate 100 is load bearing and may be secured to a table. The bottom plate 100 is generally made of metal, has high strength and is not easily deformed, thereby facilitating the lifting of the precision of the liquid injection chamber 300 and the movement of the residual liquid collecting assembly 400. The base plate 100 may have a bar shape, a rectangular shape, or the like. The liquid injection device 10 has a liquid injection station and a loading station arranged at intervals along a first direction. For an elongated base plate 100, the first direction may coincide with the extension direction of the base plate 100. As shown in fig. 1, the first direction refers to a horizontal direction, and the second direction perpendicular to the first direction refers to a vertical direction.
The platform 200 is used to mount a pour cup (not shown). Moreover, the bearing platform 200 can also be made of a metal material with high strength and difficult deformation. The bearing platform 200 is fixedly arranged at the liquid injection station and arranged at an interval with the bottom plate 100 in the second direction. Therefore, a channel is formed between the bottom plate 100 and the supporting platform 200. Specifically, the supporting platform 200 may be fixed to the base plate 100 by a bracket, or may be fixed to the worktable.
The electrolyte injection chamber 300 is used for installing a battery shell (not shown), and the electrolyte injection device 10 is used for injecting electrolyte into an empty battery shell. The electrolyte injection chamber 300 can generally fix a plurality of battery cases at the same time, thereby realizing the simultaneous electrolyte injection of a plurality of battery cases. Specifically, in the present embodiment, the liquid injection cavity 300 is a cavity structure with an opening at one end, and a plurality of battery cases to be injected can be accommodated inside the cavity structure to be fixed. Moreover, the liquid injection cavity 300 can be conveniently vacuumized, so that the subsequent liquid injection effect is improved.
Further, the injection cavity 300 is disposed on the bottom plate 100 and can slide between the injection station and the loading station. Specifically, the injection cavity 300 is located between the channel formed by the bottom plate 100 and the supporting platform 200, and can slide in the channel. The injection device 10 may be provided with a power assembly (e.g., a motor) to drive the injection chamber 300 to slide on the base plate 100 in the first direction, or may be driven by an external power assembly.
When the liquid injection cavity 300 slides to the feeding station, the battery shell after liquid injection is finished can be taken out, and the battery shell to be injected is loaded; when the liquid injection chamber 300 slides to the liquid injection station, the lifting assembly 500 can drive the liquid injection chamber 300 to move along the second direction, so that the battery shell and the liquid receiving cup 410 are in butt joint, and liquid injection is completed; after the liquid injection is completed, the lifting assembly 500 drives the liquid injection chamber 300 to move in the second direction and reversely, so as to separate the battery case from the liquid receiving cup 410. The electrolyte injection process of the battery shell can be realized by circulating the process.
In this embodiment, the injection device 10 further includes a first mounting plate 600 slidably mounted to the base plate 100. The lift assembly 500 includes a first cylinder 510, the first cylinder 510 being secured to the first mounting plate 600, and the injection chamber 300 being secured to the drive end of the first cylinder 510.
The first mounting plate 600 can be mounted on the base plate 100 by means of the guide rail and the slider, so that the sliding is more stable. The first cylinder 510 is slidable with the first mounting plate 600 and is configured to drive the striper chamber 300 in a second direction relative to the first mounting plate 600 to engage and disengage the battery housing on the striper chamber 300 with and from the striper cup on the platform 200.
Further, in the present embodiment, the bottom plate 100 is provided with limiting members 110 at two ends, and the limiting members 110 are used for limiting the movement of the first mounting plate 600.
The two limiting members 110 are arranged at intervals in the first direction, and the first mounting plate 600 is abutted against the limiting members 110 to limit the movement. For the elongated base plate 100, two position-limiting members 100 are respectively located at two opposite ends of the base plate 100. The position of the limiting members 110 is calibrated in advance, and when the bottom plate 100 abuts against the two limiting members 110, the liquid injection cavity 300 is just located at the feeding station and the liquid injection station, respectively. Therefore, the position of the injection cavity 300 can be quickly positioned by the limiting member 110, so that the injection cavity 300 can be accurately moved to the loading station or the injection station.
In order to reduce the impact, the battery case attached to the injection chamber 300 is prevented from falling off. Specifically, in the present embodiment, the limiting member 110 is a buffer. The buffer can be a spring, a damper or other elastic energy storage elements. Therefore, when the first mounting plate 600 can slide to abut against the limiting member 110, the limiting member 100 can effectively absorb kinetic energy, thereby avoiding hard contact.
The residual liquid collecting assembly 400 comprises a liquid receiving cup 410, and when the liquid receiving cup 410 is in butt joint with a liquid injection cup on the bearing platform 200, residual liquid collection can be achieved. The raffinate collection assembly 400 is linked to the injection chamber 300, and the liquid receiving cup 410 is located at the injection station when the injection chamber 300 slides to the loading station.
When the liquid receiving cup 410 is located at the liquid injection station, the lifting assembly 500 can drive the liquid receiving cup 410 to move along the second direction, so that the liquid receiving cup 410 is in butt joint with the liquid injection cup, and therefore residual liquid collection is achieved; after collecting the residual liquid, the lifting assembly 500 can drive the liquid receiving cup 410 to move reversely in the second direction, so that the liquid receiving cup 410 is separated from the liquid injecting cup.
When the liquid injection device 100 performs the liquid injection process, the liquid injection cavity 300 and the liquid receiving cup 410 are alternately positioned at the liquid injection station. After the primary liquid injection is completed, the liquid injection cavity 300 can be slid to the feeding station, and then the liquid receiving cup 410 is driven to come to the liquid injection station. The liquid injection cavity 300 completes discharging of the battery shell after liquid injection at the charging station and charging of the battery shell to be injected. Meanwhile, the liquid receiving cup 410 collects the residual liquid of the liquid injection cup at the liquid injection station. Therefore, the residual liquid collection and the charging process of the battery shell are not interfered with each other and can be carried out simultaneously.
Moreover, only one calibration positioning of the raffinate collection assembly 400 is required. That is, when the receiving cup 410 is at the priming station for the first time, the positions of the receiving cup 410 and the priming cup can be calibrated until the two are aligned. Therefore, the liquid injection cup 410 can be aligned with the liquid injection cup when being driven by the liquid injection cavity 300 to move to the liquid injection station, and repeated positioning is not needed.
The manner of collecting the residual liquid in the liquid receiving cup 410 can be various. For example, the liquid can be pressurized or the cup 410 can be evacuated to create a negative pressure that draws the residue away from the cup.
Specifically, in this embodiment, the raffinate collecting assembly 400 further includes a vacuum generator 440, and the vacuum generator 440 is in communication with the liquid receiving cup 410.
The vacuum generator 440 can generate negative pressure inside the liquid receiving cup 410, thereby sucking out the electrolyte remaining in the liquid filling cup. The liquid receiving cup 410 is generally provided in a plurality, so that a plurality of liquid pouring cups can be cleaned independently at the same time. Finally, vacuum generator 440 may be in communication with a waste reservoir (not shown) from which the collected raffinate is stored.
Further, referring to fig. 5 and fig. 6, in the present embodiment, the liquid receiving cup 410 includes a first section 412, a second section 414, and a connecting section 416 for connecting the first section 412 and the second section 414, a pipe diameter of the first section 412 is larger than that of the second section 414, the second section 414 is connected to the vacuum generator 440, and the connecting section 416 is funnel-shaped.
Specifically, the liquid receiving cup 410 has a hollow cylindrical structure. The outer wall of the second section 414 may be provided with a slot, a thread, etc. Moreover, since the tube diameter of the second section 414 is small, reliable communication with the vacuum generator 400 is achieved. Due to the difference of pipe diameters between the first section 412 and the second section 414, the funnel-shaped connecting section 416 can better play a role in transition and better guide the electrolyte entering the liquid receiving cup 410, so as to prevent the electrolyte from accumulating at the connecting part of the first section 412 and the second section 414 to cause blockage.
The residual liquid collecting assembly 400 and the liquid injection chamber 300 can be linked through an intermediate connecting piece or can be directly connected to realize linkage.
Referring to fig. 1 again, in the present embodiment, the residual liquid collecting assembly 400 further includes a fixing bracket 420 and a second mounting plate 430. The fixing bracket 420 is fixedly connected with the injection cavity 300, the second mounting plate 430 is mounted on the fixing bracket 420, and the liquid receiving cup 410 is mounted on the second mounting plate 430.
Specifically, the fixing bracket 420 and the second mounting plate 430 are both made of metal, so that they are not easily deformed. The fixing bracket 420 can be directly fixed with the liquid injection chamber 300 by welding, thread fastening and the like, thereby avoiding the use of an intermediate connecting piece and effectively simplifying the structure of the liquid injection device 10. Moreover, the transmission between the liquid injection cavity 300 and the residual liquid collecting component 400 is more direct, which is beneficial to ensuring the transmission precision.
Further, in this embodiment, the lifting assembly 500 further includes a second cylinder 520, the second cylinder 520 is fixed to the fixing bracket 420, and the second mounting plate 430 is slidably mounted on the fixing bracket 420 and is in transmission connection with a driving end of the second cylinder 520.
The second mounting plate 430 may be slidably mounted to the fixing bracket 420 by means of a slider-to-rail fit. Also, the sliding direction of the second mounting plate 430 coincides with the second direction. When the liquid receiving cup 410 is located at the liquid injecting station, the second cylinder 520 drives the second mounting plate 430 to slide, so that the liquid receiving cup 410 can be driven to be in butt joint with or separated from the liquid injecting cup on the bearing platform 200.
It should be noted that in other embodiments, the same drive member (e.g., linear motor or cylinder) may be used for the liquid receiving cup 410 and the liquid pouring chamber 300 to achieve the elevation in the second direction. That is, the drip cup 410 and the drip chamber 300 can be lifted and lowered at the same time to allow either one of them to be docked with or undocked from the drip cup on the platform 200.
Further, referring to fig. 5 and fig. 6 again, in the present embodiment, the liquid receiving cup 410 includes a blocking piece 411 disposed along the circumferential direction, the liquid receiving cup 410 is disposed through the second mounting plate 430, and the blocking piece 411 abuts against the surface of the second mounting plate 430.
The stopper 411 is integrally formed with the body of the liquid-receiving cup 410. Mounting holes can be reserved on the second mounting plate 430, and the aperture of the mounting holes is slightly larger than the outer diameter of the main body of the liquid receiving cup 410 and smaller than the outer diameter of the blocking piece 411. Therefore, when liquid receiving cup 410 passes through the mounting hole, baffle 411 can abut against second mounting plate 430, thereby effectively preventing liquid receiving cup 410 from moving up and down. Specifically, the blocking piece 411 may be provided with a screw hole and is fixed to the second mounting plate in cooperation with a threaded fastener.
After the electrolyte remaining in the liquid pouring cup enters the liquid receiving cup 410, crystals may be formed inside the liquid receiving cup 410 because the electrolyte may not be discharged in time. During the next collection of the residual liquid, when the liquid receiving cup 410 is butted with the liquid injection cup, the crystallization of the electrolyte in the liquid receiving cup 410 may cause cross contamination to the liquid injection nozzle of the liquid injection cup.
In order to avoid the cross contamination caused by the above reasons, in this embodiment, the filling device 10 further has a cleaning station located on a side of the filling station opposite to the loading station, and when the filling chamber 300 slides to the filling station, the liquid receiving cup 410 is located at the cleaning station.
The cleaning station, the liquid injection station and the feeding station are all spaced in the first direction. As shown in fig. 1, the liquid injection station is located in the middle, and the loading station and the cleaning station are respectively located on the left side and the right side of the liquid injection station. By presetting the distance between the cleaning station and the liquid injection station, the liquid injection chamber 300 can slide to the liquid injection station, and the liquid receiving cup 410 is just positioned at the cleaning station.
Further, the liquid injection device 10 further comprises a cleaning assembly 700 arranged at the cleaning station and used for cleaning the liquid receiving cup 410 at the cleaning station. When the injection chamber 300 is positioned at the injection station, the liquid-receiving cup 410 is positioned at the cleaning station. Therefore, the liquid injection operation of the battery shell and the cleaning operation of the butt joint liquid cup 410 can be simultaneously carried out, so that the efficiency of liquid injection and residual liquid collection cannot be influenced.
Further, in the present embodiment, the cleaning assembly 700 includes a nozzle 710 and a reservoir (not shown) in communication with the nozzle 710, wherein the nozzle 710 is used for injecting the cleaning solution in the reservoir into the receiving cup 410.
Specifically, the nozzle 710 may be fixed by the washing bracket 720. Nozzle 710 injects a cleaning fluid into cup 410 to flush away electrolyte remaining in cup 410. Optionally, the cleaning solution is an electrolyte solvent, and may react with the residual electrolyte, so as to effectively prevent the electrolyte from forming crystals in the liquid receiving cup 410.
Also, when the lift assembly 500 actuates the battery housing into docking with the pour cup, the pour cup 410 is docked with the nozzle 710. That is, the movement of the nozzle 710 and the injection chamber 300 in the second direction is synchronized. When the pour chamber 300 is raised to allow the battery case to dock with the pour cup, the drip cup 410 just docks with the nozzle 710. It can be seen that the cleaning process performed on the liquid cup 410 and the liquid injection process performed on the battery case are performed simultaneously, and the cleaning process performed on the liquid cup 410 does not affect the normal liquid injection process. Moreover, since the nozzle 710 is in contact with the liquid receiving cup 410, the cleaning liquid can be prevented from being spilled.
The operation of the above-mentioned liquid injection device 100 will be briefly described with reference to the accompanying drawings:
the battery shell is filled with liquid, the liquid filling cavity 300 is positioned at a liquid filling station, and the liquid receiving cup 410 is positioned at a cleaning station. Under the driving of the driving assembly 500, the pouring chamber 300 and the liquid receiving cup 410 are lifted, the battery shell in the pouring chamber 300 is butted with the pouring cup on the carrying platform 200, and the liquid receiving cup 410 is butted with the nozzle 710. At this time, the state of the liquid injection device 100 is as shown in fig. 1;
after the injection is completed, the driving assembly 500 drives the injection chamber 300 and the receiving cup 410 to move back to prepare for the next process. At this time, the state of the liquid injection device 100 is as shown in fig. 2;
the preparation begins to carry out the raffinate and collects, annotates liquid chamber 300 and moves to the material loading station under power component's drive, and liquid cup 410 moves to annotating liquid station below along with annotating the removal of liquid chamber 300. At this time, the state of the liquid injection device 100 is as shown in fig. 3;
and collecting residual liquid, wherein the driving assembly 500 drives the liquid receiving cup 410 to ascend, and the liquid receiving cup 410 is butted with a liquid injection cup on the liquid injection bearing platform 200. Meanwhile, the battery shell which is filled with the liquid in the liquid filling cavity 300 on the feeding station can be taken out and filled with the battery shell to be filled with the liquid. At this time, the state of the liquid injection device 100 is as shown in fig. 4;
after the residual liquid is collected, the liquid injection device 10 returns to the state shown in fig. 1, and performs the next liquid injection and cleans the liquid cup 410. The processes are circulated in sequence, and the liquid injection process of the battery shell can be continuously executed.
In the liquid filling device 10, the liquid filling chamber 300 and the liquid receiving cup 410 can be alternately positioned at the liquid filling station because the liquid filling chamber 300 is linked with the residual liquid collecting assembly 400. After the primary liquid injection is completed, the liquid injection cavity 300 can be slid to the feeding station, and then the liquid receiving cup 410 is driven to come to the liquid injection station. Therefore, the residual liquid collecting assembly 400 is calibrated and positioned only once, so that the liquid receiving cup 410 at the liquid injection station is aligned with the liquid injection cup, and repeated positioning is not needed subsequently. Moreover, the processes of collecting the residual liquid and feeding the battery shell are not interfered with each other, so that the residual liquid collection and the feeding of the battery shell can be carried out simultaneously. Therefore, the injection device 10 can significantly improve the efficiency of the injection process.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
