Description

Technical Field

[0001] The utility model relates to the technical field of battery detection, in particular to a detection device for a negative pressure system of a formation cabinet. Background Art

[0002] Secondary batteries, also known as rechargeable batteries or storage batteries, refer to batteries that can be recharged to activate the active materials and continue to be used after the battery is discharged. As an emerging energy source, secondary batteries have been widely used due to their high efficiency, pollution-free and recyclable advantages. During the preparation of secondary batteries, it is necessary to complete the formation process to activate the battery, which specifically refers to the process of placing the battery in the corresponding formation cabinet, activating the negative electrode of the battery and forming an SEI film (Solid Electrolyte Interface) on its surface.

[0003] In this process, various gases are often generated due to side reactions between the negative electrode of the battery and the electrolyte. The generated gases will be extracted from the electrolyte through the negative pressure system of the formation cabinet. Since batteries are generally produced in a high temperature and low dew point environment, the electrolyte is easy to crystallize after a period of use, resulting in blockage of the pipeline of the negative pressure system of the formation cabinet. If it is not discovered and handled in time, the various gases generated during the battery formation process will not be discharged and will be retained in the battery, which will cause the battery shell to swell, be scrapped, or even explode, causing great harm and loss. Therefore, it is very necessary to timely detect whether the pipeline of the negative pressure system of the formation cabinet is blocked.

Therefore, for multiple types of formation cabinets, multiple sets of detection devices need to be equipped, which greatly increases the cost of battery production and causes a waste of resources, and cannot meet the current production needs.

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] See also Figure 1 to Figure 4 The detection device of the negative pressure system of a forming cabinet of the embodiment of the utility model comprises a plurality of negative pressure suction nozzles 2, a detection box 3 and a plurality of detection hoses 4. The plurality of negative pressure suction nozzles 2 are arranged in the cabinet of the forming cabinet 1 to connect the negative pressure system of the forming cabinet 1 with the outside. When the negative pressure system of the forming cabinet 1 is not detected, the plurality of negative pressure suction nozzles 2 are in a closed state. The detection box 3 is arranged outside the cabinet of the forming cabinet 1, and an air pressure detector is arranged on the detection box 3.

[0031] When the negative pressure system of the formation cabinet 1 is detected, a plurality of negative pressure nozzles 2 are opened first, and then one end of a plurality of detection hoses 4 is communicated with the air pressure detector, and the other end is communicated with the plurality of negative pressure nozzles 2 respectively, so that the negative pressure system of the formation cabinet 1 is detected by the air pressure detector. The air pressure detector is used to judge whether the pipeline of the negative pressure system of the formation cabinet 1 is blocked, so as to prevent the various gases generated in the battery formation process from being unable to be discharged and being retained in the battery, thereby causing the battery shell to swell, be scrapped, or even explode.

[0032] In the prior art, the device for detecting the negative pressure system of the formation cabinet 1 is configured separately according to the type of the formation cabinet 1. Specifically, according to different types of formation cabinets 1, a detection box 3 is separately provided, and an air pressure detector is provided on the detection box 3, and a plurality of detection channels are used to respectively connect the air pressure detector with a plurality of negative pressure nozzles 2 of the formation cabinet 1.

[0033] Since different types of chemical formation cabinets 1 have different numbers and positions of negative pressure nozzles 2, the detection channels of the detection boxes 3 configured according to different types of chemical formation cabinets 1 correspond one to one with the negative pressure nozzles 2 of the chemical formation cabinet 1. When performing the detection of the negative pressure system of the chemical formation cabinet 1, the detection box 3 is installed in the cabinet of the chemical formation cabinet 1, so that the multiple detection channels of the detection box 3 are respectively opposite to the multiple negative pressure nozzles 2 of the chemical formation cabinet 1, thereby detecting whether the pipeline of the negative pressure system of the chemical formation cabinet 1 is blocked through the air pressure detector on the detection box 3.

[0034] Since the detection box 3 configured for one type of formation cabinet 1 has a size that is only compatible with the size of the formation cabinet 1 of this type, and the number and position of its detection channels are only compatible with the negative pressure nozzle 2 of the formation cabinet 1 of this type, it cannot be applied to other types of formation cabinets 1. Therefore, for multiple types of formation cabinets 1, it is necessary to equip multiple sets of detection devices, which greatly increases the cost of battery production and causes a waste of resources, and cannot meet the current production needs.

[0035] In the present application, the detection box 3 for detecting the negative pressure system of the formation cabinet 1 is arranged outside the cabinet of the formation cabinet 1 and does not need to be installed inside the cabinet of the formation cabinet 1. Therefore, the size of the detection box 3 of the detection device does not need to be designed according to the size of a single type of formation cabinet 1, so that when the detection box 3 detects the negative pressure system of other types of formation cabinets 1, there is no need to consider the problem that the size of the detection box 3 is not compatible with the size of other types of formation cabinets 1.

[0036] Furthermore, since the detection device connects the multiple negative pressure nozzles 2 of the formation cabinet 1 with the air pressure detector through multiple detection hoses 4, and the detection hoses 4 have deformability, the multiple negative pressure nozzles 2 of different types of formation cabinets 1 have different positions, and the multiple detection hoses 4 can respectively connect the multiple negative pressure nozzles 2 with the air pressure detector of the detection box 3. Moreover, according to the different numbers of negative pressure nozzles 2 of different types of formation cabinets 1, the number of detection hoses 4 can be increased or decreased accordingly, so that the detection device can meet the negative pressure system detection requirements of different types of formation cabinets 1, thereby greatly reducing the production cost and saving resources.

[0037] In this embodiment, the detection device also includes an adapter, which is arranged in the cabinet body of the formation cabinet 1. The other end of the detection hose 4 is connected to the corresponding negative pressure suction nozzle 2 through the adapter, so that the connection between the detection hose 4 and the negative pressure suction nozzle 2 is simpler, more convenient, and easier to implement, thereby enhancing the practicality of the detection device.

[0038] Specifically, in the present application, the adapter is a plurality of discarded batteries 5 that are detachably mounted in the cabinet of the formation cabinet 1. Since the discarded batteries 5 themselves have a cavity and a liquid injection port for injecting electrolyte into the cavity, the liquid injection port of the discarded batteries 5 communicates the cavity of the discarded batteries 5 with the outside world. When actually implemented, first, according to different types of formation cabinets 1, a corresponding number of discarded batteries 5 are installed in the cabinet of the formation cabinet 1, so that the liquid injection holes of a plurality of discarded batteries 5 are respectively opposite to a plurality of negative pressure suction nozzles 2 of the formation cabinet 1, thereby a plurality of negative pressure suction nozzles 2 of the formation cabinet 1 are respectively communicated with the cavities of a plurality of discarded batteries 5.

[0039] Then, one end of the multiple detection hoses 4 connected to the multiple negative pressure suction nozzles 2 is connected to the cavities of the multiple discarded batteries 5 respectively, so that the multiple detection hoses 4 are connected to the multiple negative pressure suction nozzles 2 through the multiple discarded batteries 5 respectively, which makes the connection between the detection hoses 4 and the negative pressure suction nozzles 2 simpler, more convenient and easier to implement, thereby enhancing the practicability of the present detection device, and also makes use of the discarded batteries 5, further reducing production costs and saving resources.

[0040] Specifically, in the present application, each waste battery 5 is provided with a threaded hole, which connects the cavity of the waste battery 5 with the outside. One end of each detection hose 4 used for connecting with the negative pressure suction nozzle 2 is provided with an external threaded joint, and the end of the detection hose 4 is screwed onto the corresponding waste battery 5 through the cooperation of the external threaded joint and the threaded hole, so that the detection hose 4 can be connected with the cavity of the waste battery 5, and then the detection hose 4 can be connected with the negative pressure suction nozzle 2.

[0041] In the present embodiment, the reason why the detection hose 4 is connected with the negative pressure suction nozzle 2 through the conversion of the discarded battery 5 is that the negative pressure suction nozzle 2 is non-detachably arranged in the cabinet body of the formation cabinet 1. Compared with providing an internal thread on the negative pressure suction nozzle 2 for screwing with the external threaded joint of the detection hose 4 to realize the connection between the detection hose 4 and the negative pressure suction nozzle 2, the operation of providing a threaded hole on the discarded battery 5 detachably installed on the formation cabinet 1 in the present application is easier to implement, and the discarded battery 5 itself has a cavity, as well as a liquid injection port that connects the cavity of the discarded battery 5 with the outside world, and no other hole opening operation is required, thereby making the connection between the detection hose 4 and the negative pressure suction nozzle 2 simpler and more convenient, easy to implement, and enhancing the practicality of the present detection device.

[0042] In actual production, for the battery that reaches the scrap standard, the staff can carry out centralized treatment to the electrolyte in the battery to prevent it from harming the environment. Therefore it is foreseeable that: in the present application, the used waste battery 5 is a battery that reaches the scrap standard and the electrolyte in its cavity has completely run off. Because the size of a single battery is smaller than the size of the internal space of the formation cabinet 1, therefore for different types of formation cabinets 1, the quantity of the waste battery 5 is increased or reduced in the cabinet of the formation cabinet 1, and will not be affected by the size of the formation cabinet 1, thereby enabling this detection device to meet the negative pressure system detection demand of different types of formation cabinets 1.

[0043] In the present embodiment, the detection box 3 comprises a plurality of side beams 31, and the plurality of side beams 31 are connected end to end, so that the plurality of side beams 31 are surrounded in a circle to form a rectangular frame. The air pressure detector is a plurality of barometers 32, and the plurality of barometers 32 are axially arranged on one of the side beams 31 of the rectangular frame, one end of the detection hose 4 is connected to a barometer 32, and the other end is connected to a negative pressure suction nozzle 2, so that the plurality of positions of the negative pressure system of the formation cabinet 1 are respectively detected by the plurality of barometers 32, so as to better judge whether the pipeline of the negative pressure system of the formation cabinet 1 is blocked.

[0044] It is foreseeable that: in actual production, the number of barometers 32 of the detection device corresponds to the number of negative pressure nozzles 2 arranged in the body of the formation cabinet 1, so that multiple barometers 32 can respectively pass through multiple negative pressure nozzles 2 to simultaneously detect multiple positions of the negative pressure system of the formation cabinet 1. Since the detection device of the present application can be applied to different types of formation cabinets 1, the number of barometers 32 arranged on the detection box 3 can exceed the number of negative pressure nozzles 2 of different types of formation cabinets 1.

[0045] When testing the negative pressure systems of different types of chemical forming cabinets 1, the number of detection hoses 4 is increased or decreased accordingly according to the number of negative pressure suction nozzles 2 arranged in the chemical forming cabinet 1, so that each negative pressure suction nozzle 2 is connected to the corresponding air pressure gauge 32 through the detection hose 4, so that the detection device can meet the negative pressure system detection requirements of different types of chemical forming cabinets 1.

[0046] As mentioned in the previous embodiments, since the detection box 3 of the present application is arranged outside the cabinet body of the chemical formation cabinet 1, the size of the detection box 3 may not be limited by the size of the chemical formation cabinet 1. Therefore, when multiple pressure gauges 32 are axially arranged on one of the side beams 31 of the rectangular frame, the size of the rectangular frame can be appropriately increased, and the multiple pressure gauges 32 are axially arranged on a longer side beam 31 of the rectangular frame, so as to meet the requirement of the pressure gauges 32 whose number exceeds the number of negative pressure nozzles 2 of different types of chemical formation cabinets 1, and are axially arranged on the side beam 31.

[0047] In this embodiment, the detection box 3 also includes a crossbeam 33, which is arranged in the middle of a rectangular frame surrounded by a plurality of side beams 31, and the crossbeam 33 connects two oppositely arranged side beams 31. In this application, a plurality of negative pressure nozzles 2 are arranged in the cabinet of the formation cabinet 1, a plurality of barometers 32 are arranged on the detection box 3, and the plurality of negative pressure nozzles 2 are connected to the plurality of barometers 32 through a plurality of detection hoses 4, respectively. In this process, the routing of the plurality of detection hoses 4 is chaotic, which easily causes entanglement and pulling between the detection hoses 4, thereby affecting both the service life of the detection hoses 4 and the detection effect of the detection device.

[0048] Therefore, in the present application, when one end of the detection hose 4 is connected to the barometer 32 and the other end is connected to the negative pressure nozzle 2, the middle part of the detection hose 4 is routed on the crossbeam 33, so that the middle part of the detection hose 4 is limited by the crossbeam 33, and then when the negative pressure system of the formation cabinet 1 is tested, the routing of multiple detection hoses 4 is made more regular, which not only ensures the service life of the detection hose 4, but also ensures the detection effect of the present detection device.

[0049] In this embodiment, a plurality of wiring grooves 331 are provided on the cross beam 33. The plurality of wiring grooves 331 are arranged longitudinally on the cross beam 33 and extend axially, so that one end of each of the wiring grooves 331 passes through one of the side beams 31 connected to the cross beam 33. When the plurality of negative pressure suction nozzles 2 are connected to the plurality of barometers 32 through the plurality of detection hoses 4, one end of the detection hose 4 is first connected to the barometer 32, and the other end is routed in the corresponding wiring groove 331, and one end of the side beam 31 is extended out of the detection box 3 through the wiring groove 331, and then the other end of the detection hose 4 is fixed to the corresponding waste battery 5 by threaded connection, and the waste battery 5 is transferred so that the other end of the detection hose 4 is connected to the corresponding negative pressure suction nozzle 2.

[0050] In this process, the plurality of routing grooves 331 respectively limit the middle parts of the plurality of detection hoses 4, further making the routing of the plurality of detection hoses 4 more regular, thereby ensuring the service life of the detection hoses 4 and the detection effect of the detection device.

[0051] In the present application, a plurality of barometers 32 are axially arranged on the side beam 31, and in order to facilitate the detection of the connection between one end of the hose 4 and the barometer 32, and the routing of the other end in the corresponding wiring groove 331, the axial extension length of each wiring groove 331 on the cross beam 33 needs to be determined according to the axial position of the barometer 32 corresponding to the wiring groove 331 on the side beam 31, so that the axial extension length range of the wiring groove 331 on the cross beam 33 covers the axial position of the corresponding barometer 32 on the side beam 31, thereby making the routing of the detection hose 4 simpler, more convenient, and easier to implement, thereby enhancing the practicality of the detection device.

[0052] In this embodiment, each wiring groove 331 is provided with binding holes 332 on the upper and lower sides. When one end of the detection hose 4 is connected to the barometer 32 and the other end is routed in the corresponding wiring groove 331, a cable tie can be used to pass through the binding holes 332 on the upper and lower sides of the wiring groove 331 to bind and fix the detection hose 4, thereby further making the routing of multiple detection hoses 4 more regular, which not only ensures the service life of the detection hose 4, but also ensures the detection effect of the detection device.

[0053] In specific implementation, since each wiring groove 331 has a different axial extension length on the crossbeam 33, the lengths of the multiple detection hoses 4 routed in the multiple wiring grooves 331 are also different, so the multiple detection hoses 4 can be tied and fixed by cable ties at different axial positions on the crossbeam 33. Therefore, in this application, the tying holes 332 between two adjacent wiring grooves 331 can be shared, that is, the tying holes 332 on the upper side of the wiring groove 331 located below are the same as the tying holes 332 on the lower side of the wiring groove 331 located above, so that the implementation of the detection device is simpler and more convenient.

[0054] In actual production, the detection device of the present application needs to detect the negative pressure systems of different types of formation cabinets 1, and different types of formation cabinets 1 are usually distributed in various locations in the workshop or in different workshops. Therefore, in the present embodiment, the detection device also includes a mobile cart 6, a universal wheel 61 is provided at the bottom of the mobile cart 6, and a pushing handle 62 is provided on one side of the mobile cart 6. The detection box 3 is placed on the mobile cart 6. By pushing the handle 62, the mobile cart 6 can be pushed to move, thereby driving the detection box 3 to move, thereby making the movement of the detection device simple and convenient, and easy to implement.

[0055] Due to the different types of formation cabinets 1 and the different heights of the negative pressure systems inside the cabinets, the heights of the negative pressure nozzles 2 used to connect the negative pressure systems with the outside world are different. Therefore, in the present application, a telescopic cylinder 63 is vertically arranged on the mobile trolley 6, and a support platform 64 is arranged on the top of the telescopic cylinder 63.

[0056] A limiting groove 641 is provided on the support platform 64. When the detection box 3 is placed on the support platform 64, the limiting groove 641 limits the detection box 3. The support platform 64 and the detection box 3 can be driven to move in the vertical direction by the extension and contraction of the telescopic cylinder 63, so that when the detection box 3 is located on the mobile trolley 6, the height of the detection box 3 can be adjusted accordingly according to different types of formation cabinets 1, so that the use of the detection device is simpler and more convenient, and easy to implement.
