A type of workwear

Abstract

This application relates to a tooling, belonging to the field of battery manufacturing technology. The tooling has a cavity containing a plurality of isolation platforms on at least one side of its cavity wall. These isolation platforms are spaced apart along a first direction. The isolation platforms support a negative electrode coating and a current collector with the negative electrode coating. The cavity contains a positive electrode coating. Each isolation platform has an injection hole, which communicates with both the cavity and the side of the cavity wall opposite to the cavity. By supporting the edges of the negative electrode coating and the current collector with the negative electrode coating through the isolation platforms, insulating adhesive can flow through the injection holes into the gaps between two adjacent negative electrode coatings to support both the negative electrode coating and the current collector. This eliminates the need to individually inject insulating adhesive into each gap of the negative electrode coating and eliminates the need to adjust the position of the current collector during the injection of insulating adhesive, thereby improving battery production efficiency.

Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, specifically to a tooling. Background Technology

[0002] To prevent short circuits in the electrodes stacked on both sides of the electrolyte layer along its thickness, the electrodes on both sides are of unequal size, with one side's electrode being larger in both length and width than the other. This results in the larger electrode's edge being unsupported and suspended. To ensure good conductivity at the solid-solid interface, the electrodes and electrolyte need to be pressed together during battery fabrication. The unsupported edges of the larger electrode will collapse or break circumferentially under pressure, causing a short circuit. Therefore, insulating adhesive needs to be introduced around the smaller electrode to support and insulate it.

[0003] In related technologies, insulating adhesive is introduced around smaller electrodes using a dispensing machine to support larger electrodes. However, dispensing with a dispensing machine requires individual dispensing of adhesive to multiple electrodes, and the alignment of the electrodes needs to be adjusted during the dispensing process. This cumbersome procedure results in low battery production efficiency. Summary of the Invention

[0004] This application provides a tooling to improve battery production efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides a tooling having a receiving cavity and an injection hole. At least one side of the cavity wall of the receiving cavity is provided with a plurality of isolation platforms, which are arranged at intervals along a first direction. The isolation platforms are used to support a negative electrode coating and a current collector having the negative electrode coating. The receiving cavity is used to receive a positive electrode coating. The isolation platforms are provided with the injection hole, which is connected to the receiving cavity and the side of the cavity wall of the receiving cavity away from the receiving cavity.

[0006] In this embodiment, the insulating adhesive can flow into the gap between every two adjacent negative electrode coatings through the injection hole to support the negative electrode coating and the current collector with the negative electrode coating, thereby improving battery production efficiency.

[0007] In some embodiments, each of the isolation platforms is provided with the injection hole.

[0008] In this embodiment, insulating adhesive is simultaneously injected into the gap between every two adjacent negative electrode coatings to improve the adhesive injection efficiency.

[0009] In some embodiments, the opening at one end of the injection hole is located on the surface of the isolation platform facing the receiving cavity.

[0010] In this embodiment, the insulating adhesive is made easier to flow directly into the outer side of the positive electrode coating where it needs to be supported, thus shortening the flow path of the insulating adhesive and improving production efficiency.

[0011] In some embodiments, each of the isolation platforms is provided with a plurality of injection holes arranged circumferentially spaced along the receiving cavity.

[0012] In this embodiment, adhesive can be injected at multiple locations along the circumference of the receiving cavity on each isolation platform, thereby improving the injection efficiency.

[0013] In some embodiments, the tooling includes: Top cover; The base is spaced apart from the top cover along a first direction; A surrounding wall is provided around the upper cover, and the surrounding wall is respectively provided on opposite sides of the upper cover and the base along the first direction, so that the surrounding wall, the upper cover and the base enclose the receiving cavity, and the surrounding wall is provided with the isolation platform and the injection hole.

[0014] In this embodiment, the accommodating cavity, which is sealed by the top cover and the base, is located on opposite sides of the first direction, which reduces the possibility of insulating adhesive flowing out of the accommodating cavity and improves the uniformity of the insulating adhesive thickness between two adjacent negative electrode coatings.

[0015] In some embodiments, the enclosure includes a first sub-component and a second sub-component, the first sub-component and the second sub-component are arranged in a second direction, the second direction is intersected with the first direction, the first sub-component and the second sub-component are detachably connected, and the first sub-component and / or the second sub-component are provided with the isolation platform.

[0016] In this embodiment, the first sub-component and the second sub-component can be disassembled along the second direction, so that the battery can be moved along the second direction relative to the first sub-component or the second sub-component to move into or out of the receiving cavity, which facilitates the movement of the negative electrode coating and the current collector with the negative electrode coating into the corresponding isolation platform along the second direction.

[0017] In some embodiments, the accommodating cavity is provided with the isolation platform on at least one side along a third direction, the third direction being arranged to intersect the first direction and the second direction respectively, and the isolation platform spanning the first sub-component and the second sub-component.

[0018] In this embodiment, the first sub-component and the second sub-component move closer to each other toward the battery on opposite sides along the second direction, reducing the travel distance of the isolation stage relative to the battery on one side along the second direction.

[0019] In some embodiments, the first sub-component and / or the second sub-component have a magnetic part, the first sub-component is attracted to the second sub-component by the magnetic attraction generated by the magnetic part, and the magnetic part can be magnetized or demagnetized.

[0020] In this embodiment, the first sub-component and the second sub-component are magnetically connected, which facilitates the assembly and disassembly of the first and second sub-components and the removal and placement of the battery.

[0021] In some embodiments, the accommodating cavity is provided with isolation platforms on opposite sides along a third direction, and the third direction is arranged to intersect the first direction and the second direction respectively.

[0022] In this embodiment, the negative electrode coating and the current collector with the negative electrode coating are respectively supported by isolation platforms on opposite sides along the third direction, which facilitates the injection of insulating adhesive on opposite sides along the third direction.

[0023] In some embodiments, the isolation platform is disposed on the first sub-component, and the second sub-component is located on one side of the isolation platform along the second direction.

[0024] In this embodiment, the second sub-component may not have an isolation platform, which facilitates the processing of the second sub-component.

[0025] The embodiments of this application have the following beneficial effects: The tooling provided in this application embodiment includes an isolation platform for supporting the negative electrode coating and the current collector with the negative electrode coating, and a receiving cavity for accommodating the positive electrode coating. The isolation platform has injection holes that communicate with the receiving cavity and the side of the cavity wall opposite to the receiving cavity. By supporting the edges of the negative electrode coating and the current collector with the negative electrode coating through the isolation platform, the deformation of the edges of the negative electrode coating and the current collector with the negative electrode coating can be reduced, thus reducing the obstruction of the gaps between two adjacent negative electrode coatings. Insulating adhesive can flow into the gaps between every two adjacent negative electrode coatings through the injection holes to support the negative electrode coating and the current collector with the negative electrode coating. It is not necessary to apply insulating adhesive to each gap of the negative electrode coating separately, and the position of the current collector does not need to be adjusted during the injection of insulating adhesive, thereby improving battery production efficiency. By supporting the negative electrode coating and the current collector with the negative electrode coating through the isolation platform, it is easier to keep the height of the gap between every two adjacent negative electrode coatings consistent along the first direction, which is beneficial to improving the uniformity of the thickness of the insulating adhesive between every two adjacent negative electrode coatings along the first direction.

It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0029] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0030] This application provides a tooling embodiment; please refer to [link / reference]. Figures 1-10 The tooling has a receiving cavity 1 and an injection hole 2. At least one side of the cavity wall of the receiving cavity 1 is provided with a plurality of isolation platforms 31. The plurality of isolation platforms 31 are arranged at intervals along a first direction. The isolation platforms 31 are used to support the negative electrode coating 102 and the current collector 101 provided with the negative electrode coating 102. The receiving cavity 1 is used to receive the positive electrode coating 103. The isolation platforms 31 are provided with injection holes 2. The injection holes 2 are respectively connected to the receiving cavity 1 and the side of the cavity wall of the receiving cavity 1 away from the receiving cavity 1.

[0031] It should be noted that "multiple" refers to at least two.

[0032] For example, the number of isolation tables 31 is two, four, six, ten, and fifteen.

[0033] For example, the first direction is parallel to the vertical direction.

[0034] For example, the cavity wall of the receiving cavity 1 without the isolation platform 31 is provided with injection holes 2.

[0035] For example, when projected along the first direction, the projection area of ​​the positive electrode coating 103 is located within the projection area of ​​the negative electrode coating 102, and at least one side edge of the projection area of ​​the positive electrode coating 103 is spaced apart from the corresponding side edge of the projection area of ​​the negative electrode coating 102.

[0036] For example, battery 10 is a bipolar battery 10.

[0037] For example, the battery 10 includes a plurality of negative electrode coatings 102 and a current collector 101 on which the negative electrode coatings 102 are disposed.

[0038] For example, the current collector 101 is a steel foil.

[0039] For example, the negative electrode coating 102 and the current collector 101 on which the negative electrode coating 102 is disposed constitute a negative electrode sheet.

[0040] For example, an electrolyte layer is provided between adjacent negative electrode coating 102 and positive electrode coating 103 along the first direction. The electrolyte layer is a solid electrolyte or a solid-liquid mixed electrolyte.

[0041] For example, insulating adhesive or molten insulating plastic is injected into the receiving cavity 1 through the injection hole 2.

[0042] The first direction is shown by arrow R1 in the figure.

[0043] In this embodiment, the isolation platform 31 is used to support the negative electrode coating 102 and the current collector 101 with the negative electrode coating 102, and the receiving cavity 1 is used to receive the positive electrode coating 103. The isolation platform 31 is provided with an injection hole 2, which is connected to the receiving cavity 1 and the side of the cavity wall of the receiving cavity 1 away from the receiving cavity 1. The isolation platform 31 supports the edges of the negative electrode coating 102 and the current collector 101 with the negative electrode coating 102, reducing the deformation of the edges of the negative electrode coating 102 and the current collector 101 with the negative electrode coating 102 that obstructs the gap between two adjacent negative electrode coatings 102. The insulating adhesive can flow into the gap between every two adjacent negative electrode coatings 102 through the injection hole 2 to support the negative electrode coating 102 and the current collector 101 with the negative electrode coating 102. It is not necessary to apply insulating adhesive to the gap of each negative electrode coating 102 separately, and the position of the current collector 101 does not need to be adjusted during the injection of insulating adhesive, thereby improving the production efficiency of the battery 10. The negative electrode coating 102 and the current collector 101 with the negative electrode coating 102 are supported by the isolation platform 31, which makes it easier to keep the height of the gap between each two adjacent negative electrode coatings 102 consistent along the first direction, which is beneficial to improving the uniformity of the thickness of the insulating adhesive between each two adjacent negative electrode coatings 102 along the first direction.

[0044] In some embodiments, please refer to Figure 3 and Figure 8 Each isolation platform 31 is equipped with an injection hole 2.

[0045] For example, the axial direction of the injection hole 2 intersects the first direction.

[0046] In this embodiment, each isolation platform 31 is provided with an injection hole 2, which can simultaneously inject insulating glue into the gap between every two adjacent negative electrode coatings 102, thereby improving the glue injection efficiency.

[0047] It is understood that the injection hole 2 is not limited to each isolation table 31. For example, some isolation tables 31 do not have injection holes 2, and the isolation tables 31 have through holes to connect the space between each two adjacent isolation tables 31.

[0048] In some embodiments, please refer to Figure 3 and Figure 8 The opening at one end of the injection hole 2 is located on the surface of the isolation platform 31 facing the receiving cavity 1.

[0049] It should be noted that the surface of the isolation platform 31 facing the receiving cavity 1 refers to the surface of the isolation platform 31 that intersects with the first direction.

[0050] For example, the opening at one end of the injection hole 2 is located on the surface of the tooling away from the receiving cavity 1.

[0051] In this embodiment, the opening at one end of the injection hole 2 is located on the surface of the isolation platform 31 facing the receiving cavity 1, and the opening at one end of the injection hole 2 faces the positive electrode coating 103, which facilitates the direct flow of insulating adhesive to the outer side of the positive electrode coating 103 where insulating adhesive support is required, shortening the flow path of the insulating adhesive and improving production efficiency.

[0052] It is understood that the opening at one end of the injection hole 2 is not limited to the surface of the isolation platform 31 facing the receiving cavity 1. Exemplarily, the opening at one end of the injection hole 2 is located on the surface of one isolation platform 31 facing the other isolation platform 31 along a first direction.

[0058] In this embodiment, each isolation platform 31 is provided with a plurality of injection holes 2 arranged circumferentially along the receiving cavity 1, which can inject glue at multiple positions along the circumference of the receiving cavity 1 on each isolation platform 31, thereby improving the glue injection efficiency.

[0059] It is understood that each isolation stage 31 is not limited to having multiple injection holes 2 spaced apart along the second direction. Exemplarily, each isolation stage 31 has only one injection hole 2.

[0060] In some embodiments, please refer to Figures 1-7 and Figure 10 The tooling includes an upper cover 4, a base 5, and a surrounding wall 3. The base 5 and the upper cover 4 are arranged at intervals along a first direction. The surrounding wall 3 is arranged around the upper cover 4. The surrounding wall 3 is arranged on the upper cover 4 and the base 5 on opposite sides along the first direction, so that the surrounding wall 3, the upper cover 4, and the base 5 form a receiving cavity 1. The surrounding wall 3 is provided with an isolation platform 31 and an injection hole 2.

[0061] For example, the enclosure 3 is detachably connected to the top cover 4 and the base 5 on opposite sides along the first direction.

[0062] For example, the upper part of the side wall of the enclosure 3 is provided with an isolation platform 31, and the upper part of the side wall of the enclosure 3 is not provided with an isolation platform 31.

[0063] For example, the side wall of the enclosure 3 that does not have an isolation platform 31 is also provided with injection holes 2.

[0064] In this embodiment, the enclosure 3 is respectively disposed on the upper cover 4 and the base 5 on opposite sides along the first direction, so that the enclosure 3, the upper cover 4 and the base 5 enclose a receiving cavity 1. The enclosure 3 is provided with an isolation platform 31 and an injection hole 2. The negative electrode coating 102 and the current collector 101 with the negative electrode coating 102 are supported by the isolation platform 31 on the enclosure 3. The enclosure 3, the upper cover 4 and the base 5 enclose a closed receiving cavity 1, reducing the possibility of the insulating adhesive flowing out of the receiving cavity 1, so that the insulating adhesive can fully fill the gap between two adjacent negative electrode coatings 102 and improve the uniformity of the insulating adhesive thickness.

[0065] It is understood that the tooling is not limited to including the top cover 4. Exemplarily, the top of the enclosure 3 is open.

The first sub-component 32 and the second sub-component 33 are detachably connected. The first sub-component 32 and / or the second sub-component 33 are provided with an isolation platform 31. The first sub-component 32 and the second sub-component 33 can be disassembled along the second direction, so that the battery 10 can be moved relative to the first sub-component 32 or the second sub-component 33 along the second direction to move into or out of the receiving cavity 1. This facilitates the movement of the negative electrode coating 102 and the current collector 101 provided with the negative electrode coating 102 onto the corresponding isolation platform 31 along the second direction.

[0072] It is understood that the first sub-component 32 and the second sub-component 33 are not detachably connected.

The third direction is arranged to intersect with the first direction and the second direction respectively. The isolation platform 31 spans across the first sub-component 32 and the second sub-component 33.

[0074] It should be noted that the third direction intersecting with the first direction and the second direction respectively means that the third direction is not parallel to the first direction and the third direction is not parallel to the second direction.

[0075] For example, the third direction intersects the first direction perpendicularly.

[0076] For example, the third direction intersects the second direction perpendicularly.

[0077] The third direction is shown by arrow R3 in the figure.

[0078] For example, the isolation platform 31 located on the third-direction side of the receiving cavity 1 extends in the second direction.

[0079] For example, a plurality of injection holes 2 on each isolation platform 31 located on the third direction side of the receiving cavity 1 are spaced apart along the second direction.

[0080] For example, a plurality of injection holes 2 on each isolation platform 31 located on one side of the receiving cavity 1 along the second direction are arranged at intervals along the third direction.

[0081] For example, the receiving cavity 1 is provided with a plurality of injection holes 2 on opposite sides along a third direction.

[0082] For example, the receiving cavity 1 is provided with a plurality of injection holes 2 on opposite sides along the second direction.

[0085] For example, the first sub-component 32 is detachably connected to the upper cover 4 and the base 5 respectively, and the second sub-component 33 is detachably connected to the upper cover 4 and the base 5 respectively.

[0086] For example, the receiving cavity 1 is not provided with an isolation platform 31 on the side facing the electrode 105 along the extension direction of the electrode 105.

[0087] For example, the tab 105 of the battery 10 is located on one side of the battery 10 along the second direction, and the receiving cavity 1 is not provided with an isolation platform 31 on the side of the receiving cavity 1 facing the tab 105 along the second direction.

[0088] For example, one tab 105 is clamped between the first sub-component 32 and the upper cover 4 along the first direction, and the other tab 105 is clamped between the first sub-component 32 and the base 5 along the first direction.

[0089] For example, one tab 105 is clamped between the second sub-component 33 and the top cover 4 along a first direction, while the other tab 105 is clamped between the second sub-component 33 and the base 5 along a first direction.

[0090] For example, the tab 105 of the battery 10 is located on one side of the battery 10 along a third direction, and the receiving cavity 1 is not provided with an isolation platform 31 on the side facing the tab 105 along a third direction.

[0091] For example, one tab 105 is clamped between the first sub-component 32 and the top cover 4 along the first direction, while the other tab 105 is clamped between the second sub-component 33 and the base 5 along the first direction.

The first sub-component 32 and the second sub-component 33 are arranged in a second direction, which facilitates the alignment of the negative electrode coating 102 and the current collector 101 with the negative electrode coating 102 to the corresponding isolation platform 31. After the negative electrode coating 102 and the current collector 101 with the negative electrode coating 102 are aligned with the corresponding isolation platform 31, the negative electrode coating 102 and the current collector 101 with the negative electrode coating 102 can be moved onto the corresponding isolation platform 31 from the second direction. The isolation platform 31 spans the first sub-component 32 and the second sub-component 33. The first sub-component 32 and the second sub-component 33 are close to each other on opposite sides of the battery 10 along the second direction, so that the negative electrode coating 102 and the current collector 101 with the negative electrode coating 102 are placed on the corresponding isolation platform 31, reducing the travel distance of the isolation platform 31 relative to the battery 10 along one side of the second direction.

[0093] It is understood that the receiving cavity 1 is not limited to having an isolation platform 31 provided on at least one side along a third direction. Exemplarily, the isolation platform 31 is located on at least one side of the receiving cavity 1 along a second direction.

The first sub-component 32 is attracted to the second sub-component 33 by the magnetic attraction generated by the magnetic part 34. The magnetic part 34 can be magnetized or demagnetized.

[0096] It should be noted that the magnetic part 34 can generate a magnetic field after being magnetized, so that the first sub-component 32 and the second sub-frame can be magnetically connected.

[0097] It should be noted that after demagnetization, the magnetic part 34 has almost no magnetic field, there is no magnetic attraction between the first sub-component 32 and the second sub-component 33, and the first sub-component 32 and the second sub-component 33 can be separated.

[0101] For example, the magnetic part 34 is demagnetized by alternating current magnetic demagnetization.

[0102] For example, the magnetic part 34 is magnetized by a DC magnetic field.

[0103] For example, the tooling is insulated from the contact area of ​​the battery 10.

[0104] For example, insulating varnish is sprayed onto the part of the tooling that contacts the battery 10.

[0105] In this embodiment, the first sub-component 32 and / or the second sub-component 33 have a magnetic part 34. The first sub-component 32 is attracted to the second sub-component 33 by the magnetic attraction generated by the magnetic part 34. The magnetic part 34 can be magnetized or demagnetized, which facilitates the assembly and disassembly of the first sub-component 32 and the second sub-component 33 and facilitates the removal and placement of the battery 10.

[0106] It is understood that, not limited to, the first sub-component 32 is detachably connected to the upper cover 4 and the base 5 respectively, nor limited to, the second sub-component 33 is detachably connected to the upper cover 4 and the base 5 respectively. Exemplarily, the first sub-component 32, the upper cover 4 and the base 5 are integrally formed, and the second sub-component 33 is not connected to the upper cover 4 and the base 5.

[0107] It is understood that the first sub-component 32 is not limited to being attracted to the second sub-component 33 by the magnetic attraction generated by the magnetic part 34. For example, the first sub-component 32 and the second sub-component 33 are not provided with the magnetic part 34, and the first sub-component 32 and the second sub-component 33 are snapped together.

[0108] In some embodiments, please refer to Figure 2 and Figure 7 Isolation platforms 31 are respectively provided on opposite sides of the receiving cavity 1 along the third direction, and the third direction is arranged to intersect with the first direction and the second direction respectively.

[0109] For example, the isolation platforms 31 on both sides of the receiving cavity 1 along the third direction are both spanned with the first sub-component 32 and the second sub-component 33.

[0110] For example, the isolation platforms 31 on both sides of the receiving cavity 1 along the third direction are both disposed on the first sub-component 32.

[0111] In this embodiment, the receiving cavity 1 is provided with isolation platforms 31 on opposite sides along the third direction. The negative electrode coating 102 and the current collector 101 with the negative electrode coating 102 are supported by the isolation platforms 31 on opposite sides along the third direction, which facilitates the injection of insulating glue on opposite sides along the third direction.

[0112] It is understood that the receiving cavity 1 is not limited to having isolation platforms 31 respectively provided on opposite sides along a third direction. Exemplarily, the isolation platform 31 is located on one side of the receiving cavity 1 along a third direction.
