Description

Technical Field

[0001] The present application relates to the technical field of battery manufacturing, and in particular to a supporting tooling. Background Art

[0002] The water-cooling plate and battery cells of the battery pack are usually connected by structural adhesive so that the water-cooling plate will not be separated from the battery cells after the battery pack is assembled. Compared with traditional connection methods such as welding and screwing, structural adhesive has good mechanical properties, thermal conductivity, aging resistance and fatigue resistance.

[0003] In the process of bonding the water-cooling plate and the battery cell with structural adhesive, a flat plate structure is usually used to support the bottom of the water-cooling plate and apply pressure to the battery cell so that the structural adhesive between the battery cell and the water-cooling plate can be compressed. Since the battery pack water-cooling plate as a whole is a plate-like structure with a certain curvature, the water-cooling plate will deform during the glue pressing process. The deformation of the water-cooling plate after glue pressing will rebound, causing a gap between the glue and the bottom of the battery cell, resulting in poor bonding effect.

[0022] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0024] At present, the interior of the battery pack 20 usually includes a battery cell 23 and a water-cooling plate 21. The battery cell 23 and the water-cooling plate 21 are usually bonded together by structural adhesive. In the bonding process between the battery cell 23 and the water-cooling plate 21 of the battery pack, a flat plate structure is usually used to support the supported surface 22 of the water-cooling plate 21. However, the existing water-cooling plate 21 products are generally plate-like structures with a certain curvature. In the process of using the flat plate structure to support the glue pressing, the water-cooling plate 21 with a curvature will deform, and the plate will rebound after deformation, causing a gap to appear between the glue and the bottom of the battery cell, thereby affecting the bonding effect.

[0025] In order to solve the problems of the related technology, an embodiment of the present application provides a supporting tool. The supporting tool provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in combination with the accompanying drawings.

[0026] like Figures 1 to 3 As shown, an embodiment of the present application provides a supporting tool, wherein the supporting tool 10 includes a fixing portion 11 and a plurality of supporting members 12, wherein the plurality of supporting members 12 are arranged in an array on the fixing portion 11, and each supporting member 12 includes a connecting portion 121 and a supporting portion 122 which are sequentially connected along a first direction X, wherein the connecting portion 121 is connected to the fixing portion 11, and wherein the supporting portion 122 is movably arranged relative to the connecting portion 121 along the first direction X, and ends of the plurality of supporting portions 122 jointly form a supporting surface, and a shape of the supporting surface matches a shape of a surface 22 to be supported.

[0027] In specific implementation, the support tooling of the embodiment of the present application can be applied to the assembly process of the water-cooling plate 21 of the battery pack 20. The support tooling 10 includes a fixing portion 11 and a plurality of support members 12. The plurality of support members 12 are arranged in an array on the fixing portion 11. The support member 12 includes a connecting portion 121 and a supporting portion 122. The connecting portion 121 is connected to the fixing portion 11 for fixing the support member 12. The supporting portion 122 is movably arranged relative to the connecting portion 121, so that the distance between the supporting surface 22 of the water-cooling plate 21 can be adjusted to achieve support for the supporting surface 22. Since the ends of the plurality of support portions 122 can jointly form a supporting surface, the shape of the supporting surface matches the shape of the supporting surface 22. Therefore, each position of the supporting surface 22 of different shapes can be supported by the supporting portion 122, so that the water-cooling plate 21 will not deform as a whole when subjected to pressure, thereby avoiding rebound and ensuring the bonding effect between the water-cooling plate 21 and the battery cell 23. Moreover, since the water-cooled plate 21 will not rebound, there is no need to always maintain the supporting tooling 10 at the bottom of the water-cooled plate 21 to maintain the shape of the water-cooled plate 21, thereby eliminating the need to add static workstations to the entire production line, thereby reducing overall costs.

[0028] It should be noted that the support tooling of the present application is not limited to supporting the water-cooled plate 21. The multiple support parts 122 of the support tooling 10 are independently and adjustable and can be supported on a supported surface 22 of any shape, so other products that need to be supported can be supported.

[0029] like Figure 1 As shown, the supporting tooling of the embodiment of the present application, wherein, in a plane perpendicular to the first direction X, the orthographic projection of the surface to be supported 22 is completely covered by the orthographic projection of the fixing portion 11 .

[0030] In a specific implementation, a plurality of support members 12 are arranged on the surface of the fixing portion 11, so that the orthographic projection of the fixing portion 11 in a plane perpendicular to the first direction X covers the orthographic projection of the surface to be supported 22, thereby ensuring that the plurality of support members 12 can support any position of the surface to be supported 22, thereby avoiding the situation where the edge of the surface to be supported 22 is not supported by the support force of the support member 12, resulting in deformation during the glue pressing process.

[0031] like Figure 1 As shown, the supporting tooling of an embodiment of the present application, wherein the connecting portion 121 is a cylindrical structure extending along the first direction X, the connecting portion 121 has an installation space inside, the supporting portion 122 includes a supporting head 123 and a supporting rod 124 connected to each other, the supporting rod 124 extends along the first direction X and is slidably arranged in the installation space, and the supporting head 123 is connected to one end of the supporting rod 124 away from the connecting portion 121.

[0032] In specific implementation, since the connecting portion 121 is a cylindrical structure extending along the first direction X, the installation space inside it also extends along the first direction X, and the support rod 124 extending along the first direction X can slide in the installation space along the first direction X, thereby driving the support head 123 to move toward the surface to be supported 22 at its corresponding position until it contacts the surface to be supported 22, thereby completing the support of the surface to be supported 22. Driven by the corresponding support rod 124, multiple support heads 123 can contact the surface to be supported 22 at their corresponding positions, so that the support positions of the multiple support heads 123 are different, and they are adapted to the shape of the surface to be supported 22, so as to complete the support effect of the surfaces to be supported 22 of different shapes. In the process of pressing the glue of the battery cell 23 into the box, it can provide reverse support force to each position of the water-cooling plate 21 to prevent the water-cooling plate 21 from being deformed, thereby avoiding the rebound phenomenon caused by the compression deformation of the water-cooling plate 21, and further avoiding the problem of lack of glue at the bottom of the battery cell 23 caused by the rebound phenomenon.

[0033] The supporting tooling of the embodiment of the present application, wherein the supporting tooling further includes a sensing element, which is connected to the supporting head 123 and is used to detect the contact state between the supporting head 123 and the surface 22 to be supported.

[0034] In specific implementation, the sensing component connected to the support head 123 can detect the contact state between the support head 123 and the surface to be supported 22. When the support head 123 moves to contact with the surface to be supported 22, the sensing component can detect the contact state between the support head 123 and the surface to be supported 22, thereby transmitting a contact signal. According to the contact signal, the support head 123 can be fixed in the contact position, thereby forming a stable support for the surface to be supported 22 and avoiding deformation of the surface to be supported 22.

[0035] Specifically, the sensing element is a force sensor or a displacement sensor. When the support head 123 is subjected to a reverse force from the supported surface 22 or when the support head 123 is slightly deformed by contact with the supported surface 22, the sensing element can detect and transmit a contact signal.

[0036] In specific implementation, when the sensing element of a support member 12 detects a contact signal, all support members 12 are in a locked state, that is, no relative movement occurs between the connecting portion 121 and the supporting portion 122. At this time, all support heads 123 can form a planar structure that matches the surface 22 to be supported.

[0037] In the supporting tooling of the embodiment of the present application, the sensing element is arranged on the surface of the supporting head 123 facing the surface to be supported 22. When the surface of the supporting head 123 facing the surface to be supported 22 contacts the surface to be supported 22, the sensing element can detect a contact signal. Such a setting improves the detection accuracy of the sensing element for the contact state, so that the shape of the supporting surface formed by the multiple supporting heads 123 of the supporting tooling 10 can be more adapted to the surface to be supported 22.

[0038] In the supporting tooling of the embodiment of the present application, the sensing element has a sensing end, and the sensing end and the surface of the supporting head 123 facing the surface to be supported 22 are in the same plane.

[0039] During specific implementation, the sensing end and the surface of the support head 123 facing the surface to be supported 22 are in the same plane, so that when the surface to be supported 22 is in contact with the surface of the support head 123 facing the surface to be supported 22, the surface to be supported 22 can be in contact with the sensing end, so that the sensing end can detect the contact signal in the first time, thereby ensuring the detection accuracy; moreover, the setting in the same plane prevents the sensing end from protruding from the surface setting of the support head 123, so that in the process of the support head 123 moving toward the surface to be supported 22, the surface to be supported 22 can be in contact with the sensing end and the surface of the support head 123 at the same time, and will not contact the sensing end first, thereby avoiding the situation where the sensing end detects the contact signal when the surface to be supported 22 is not in contact with the support head 123, thereby ensuring the detection accuracy of the sensing component.

[0040] The supporting tooling of the embodiment of the present application, wherein the supporting tooling has a positioning state and a supporting state. In the positioning state, the supporting tooling moves along the first direction X toward the surface to be supported 22, and part of the supporting portion 122 contacts the surface to be supported 22 and moves with the surface to be supported 22, and the sensing element corresponding to the part of the supporting portion 122 in contact with the surface to be supported 22 has a sensing signal; in the supporting state, all the supporting portions 122 are in contact with the surface to be supported 22, and all the sensing elements have a sensing signal, and all the supporting portions 122 are fixed to form a supporting surface for supporting the surface to be supported 22.

[0041] In specific implementation, in the positioning state, the support part 122 can move with the surface 22 to be supported after contacting the surface 22 to be supported, until the last support part 122 contacts the surface 22 to be supported, at which time the sensing end of the last support part 122 can detect the contact signal and control all the support parts 122 to be fixed at the current position, and the support tooling enters the supporting state, and the ends of each fixed support part 122 jointly form a supporting surface. By setting the positioning state and the supporting state, each support part 122 of the support tooling can form a supporting surface with the same shape as the surface 22 to be supported, and stably support the surface 22 to be supported, thereby avoiding the movement of each support part 122 when supporting the surface 22 to be supported.

[0042] like Figure 1 As shown, the supporting tooling of the embodiment of the present application, wherein, in a plane perpendicular to the first direction X, the orthographic projection of the supporting rod 124 is fully covered by the orthographic projection of the supporting head 123 .

[0043] In a specific implementation, the projection of the support head 123 covers the projection of the support rod 124, which can ensure that the support head 123 has sufficient contact area when supporting the supported surface 22, thereby avoiding the situation where the contact area between the two is too small and causes deformation of the water cooling plate 21.

[0044] In the supporting tooling of the embodiment of the present application, the supporting portion 122 has a maximum movement stroke D along the first direction X, and the maximum movement stroke D has a range: D≤10 mm.

[0045] During specific implementation, since the water-cooling plate 21 only bends slightly and its overall structure is still a flat structure, the maximum value of the maximum movement stroke D is set to 10 mm, which can not only meet the requirement that the support part 122 can support any position of the water-cooling plate 21, but also avoid the situation where the support of the support part 122 is unstable due to excessive movement stroke, or the overall cost of manufacturing the support tooling increases.

[0046] In the supporting tooling of the embodiment of the present application, a clamping portion is provided in the installation space, and a plurality of clamping protrusions spaced apart along the first direction X are provided on the outer circumferential surface of the supporting rod 124, and each clamping protrusion can be clamped in the clamping portion.

[0047] In specific implementation, when the support rod 124 moves along the first direction X until the support head 123 connected to it contacts the surface to be supported 22, the support rod 124 can be engaged with the engaging portion through its engaging protrusion, so that the support rod 124 can be fixed in this position, so that the support head 123 can stably support the surface to be supported 22.

[0048] The supporting fixture of the embodiment of the present application, wherein the supporting fixture 10 further includes a driving member, which is drivingly connected to the supporting rod 124 and is used to drive the supporting rod 124 to move in the installation space along the first direction X. The setting of the driving member can control the moving distance of the supporting rod 124, and when the supporting head 123 contacts the surface to be supported 22, the driving member can also control the supporting rod 124 to stop. It should be noted that, in the case where the driving member can control the supporting rod 124 to be fixed in the supporting position, the support rod 124 can be fixed without using the clamping portion and the clamping protrusion.

[0049] Specifically, the driving member is a driving motor or a hydraulic driving member. Both the driving motor and the hydraulic driving member can drive the support rod 124 steplessly. Moreover, when the support head 123 contacts the surface to be supported 22, the driving motor and the hydraulic driving member can also provide supporting force, so that the support head 123 can be stably supported at the bottom of the surface to be supported 22.

[0050] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
