[0053] To make the technical problems solved by the present utility model, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the present utility model will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0054] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected", "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0055] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0056] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left" and "right" are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0057] Before welding and fixing the cover plate to the side wall at the open end of the housing, it is necessary to press-fit and fix the cover plate, the battery cell and the housing to ensure the subsequent welding effect between the cover plate and the housing. In the prior art, for the press-fitting and fixing of the cover plate, the battery cell and the housing, it is usually manually pressed by workers. The manual press-fitting method not only has low press-fitting efficiency, but also has inconsistent press-fitting specifications, affecting the subsequent welding between the cover plate and the housing. In addition, the labor intensity of workers manually pressing the battery is relatively large and fatigue is easily generated.

[0058] To solve the above problems, as Figure 1 and Figure 2 shown, this embodiment provides a battery press-fitting device. The battery press-fitting device includes a horizontal clamping mechanism 100, a vertical support mechanism 200, a press-fitting mechanism 300 and a mounting fixture 400. Among them, the mounting fixture 400 is used to support the battery. The horizontal clamping mechanism 100 can clamp and position the battery horizontally relative to the preset press-fitting position. The vertical support mechanism 200 and the press-fitting mechanism 300 are arranged at both ends of the preset press-fitting position in the vertical direction. The vertical support mechanism 200 can support and position the mounting fixture 400 vertically relative to the preset press-fitting position. The output end of the press-fitting mechanism 300 can extend vertically into the open end of the battery housing and press-fit and fix the battery cell and the battery cover plate.

[0059] The battery pressing device can improve the protection of the battery by setting the installation fixture 400 to support the battery. By setting the horizontal clamping mechanism 100 to clamp and position the battery in the horizontal direction, and by setting the vertical support mechanism 200 and the pressing mechanism 300 at both ends in the vertical direction of the preset pressing position respectively, the horizontal clamping mechanism 100 can realize the horizontal positioning of the opening of the battery case in the battery relative to the preset pressing position, ensuring that the output end of the subsequent pressing mechanism 300 is directly opposite to the opening of the battery case in the vertical direction, solving the problem that the opening of the battery case deviates horizontally relative to the preset pressing position. By using the vertical support mechanism 200 to support and position the installation fixture 400 in the vertical direction, it can provide support feedback for the pressing mechanism 300 when pressing and fixing the battery, realizing the pressing and fixing of the battery cell and the battery cover plate in the battery relative to the battery case by the pressing mechanism 300, ensuring the pressing quality of the pressing mechanism 300. It not only has a good pressing effect and high pressing efficiency, but also has a high degree of automation, effectively reducing the labor intensity of the staff.

[0060] It should be noted that, in this embodiment, the vertical support mechanism 200 is arranged at the lower end in the vertical direction of the preset pressing position, and the pressing mechanism 300 is arranged at the upper end in the vertical direction of the preset pressing position, so that the vertical support mechanism 200 supports the installation fixture 400 from the lower end of the preset pressing position, and the pressing mechanism 300 extends into the opening of the battery case from the upper end of the preset pressing position to press and fix the battery cell and the battery cover plate.

[0061] In addition, in this embodiment, the battery pressing device further includes a frame 500, and the horizontal clamping mechanism 100, the vertical support mechanism 200 and the pressing mechanism 300 are all installed on the frame 500 to ensure the structural compactness and structural strength of the battery pressing device.

[0062] As an alternative solution, the horizontal clamping mechanism 100 includes two horizontal clamping components 110. Among them, the two horizontal clamping components 110 are arranged oppositely on the frame 500 along a preset direction, and the battery and the preset pressing position are arranged between the two horizontal clamping components 110. The output end of each horizontal clamping component 110 can reciprocate along the preset direction, and the preset direction is parallel to the horizontal direction. By setting two horizontally opposite horizontal clamping components 110, the battery and the preset pressing position are located between the two horizontal clamping components 110. By using the reciprocating movement of the two horizontal clamping components 110 along the preset direction, the clamping, positioning and relaxation of the battery relative to the preset pressing position can be realized.

[0063] When it is necessary to clamp and position the battery horizontally relative to the preset pressing position, when the two horizontal clamping components 110 move relative to each other in the preset direction, the battery on the mounting fixture 400 can be clamped and fixed in the preset direction, thereby realizing the horizontal clamping and positioning of the battery relative to the preset pressing position; when it is necessary to release the battery that has completed the horizontal clamping and positioning relative to the preset pressing position, the two horizontal clamping components 110 move away from each other in the preset direction to realize the release of the battery that has completed the horizontal clamping and positioning relative to the preset pressing position. It should be noted that in this embodiment, the preset direction is the left-right direction, and the two horizontal clamping components 110 are arranged opposite to each other in the left-right direction. In other embodiments, the specific direction of the preset direction can also be changed according to actual needs, and this embodiment does not make specific limitations.

[0064] Specifically, the horizontal clamping component 110 includes a first driving member 111 and a first abutting member 114. Among them, the first abutting member 114 is movably installed on the frame 500, the first abutting member 114 is connected to the output end of the first driving member 111, and the other end of the first abutting member 114 arranged opposite to each other can abut and fix the battery, and the first driving member 111 can drive the first abutting member 114 to reciprocate in the preset direction. By connecting one end of the first abutting member 114 to the output end of the first driving member 111 and driving the first abutting member 114 to reciprocate in the preset direction by the first driving member 111, the effect of the first abutting member 114 reciprocating in the preset direction is realized, so that the two first abutting members 114 can jointly clamp and fix the battery from both ends in the preset direction. It should be noted that in this embodiment, the first driving member is a cam mechanism, and the cam mechanism drives the first abutting member 114 to reciprocate in the preset direction. The cam mechanism has a simple structure and stable driving. In other embodiments, the first driving member 111 can also be a linear cylinder, a linear motor or other linear driving structures, and this embodiment does not make specific limitations.

[0065] In addition, in this embodiment, the battery is a cylindrical battery, the cylindrical battery is placed vertically on the mounting fixture 400, and the upper end of the battery case has an opening. To improve the horizontal clamping and positioning effect of the cylindrical battery, a semicircular groove is opened at one end of the first abutting member 114 that abuts against the cylindrical battery. The diameter of the semicircular groove is adapted to the diameter of the cylindrical battery, so that when the two first abutting members 114 jointly clamp and position the cylindrical battery, the semicircular grooves on the two first abutting members 114 can form a circular groove, and the cylindrical battery is accommodated and positioned in the circular groove, thereby clamping and positioning the cylindrical battery from the outer periphery of the cylindrical battery, achieving the effect of improving the horizontal clamping and positioning of the cylindrical battery. In other embodiments, the battery can also be a square battery. At this time, only the semicircular groove on the first abutting member 114 needs to be replaced with a rectangular groove adapted to the square battery, and this embodiment does not make specific limitations.

[0066] In this embodiment, a first guiding slider 1141 is provided on the first abutting member 114, and a first guiding slide rail 510 is defined in the frame 500. The first guiding slide rail 510 extends along a preset direction. The first guiding slider 1141 is in sliding fit with the first guiding slide rail 510. By providing the first guiding slider 1141 on the first abutting member 114 and providing the first guiding slide rail 510 extending along the preset direction on the frame 500, and making the first guiding slider 1141 in sliding fit with the first guiding slide rail 510, guiding can be provided for one end of the first abutting member 114 along the preset direction, the moving accuracy of the first abutting member 114 can be improved, and further the clamping and fixing effect of the first abutting member 114 on the battery can be ensured.

[0067] In an actual installation scenario, if the first driving member 111 is directly connected to the first abutting member 114, at this time the driving direction of the first driving member 111 is the preset direction, and it is necessary to sequentially connect the first driving member 111 and the first abutting member 114 along the preset direction, occupying a relatively large installation space. To save the installation space of the horizontal clamping assembly 110, as Figure 3 and Figure 4 shown, the horizontal clamping assembly 110 further includes a first adapter 112 and a second adapter 113. Among them, the first adapter 112 is rotatably installed on the frame 500, the second adapter 113 is movably installed on the frame 500, the input end of the first adapter 112 is movably connected to the output end of the first abutting member 114, the output end of the first driving member 111 can drive the first adapter 112 to rotate vertically, the input end of the second adapter 113 is movably connected to the output end of the first adapter 112, the second adapter 113 is fixedly connected to the input end of the first abutting member 114, and the first adapter 112 can drive the second adapter 113 to reciprocate along the preset direction. By rotatably connecting the input end of the first adapter 112 to the output end of the first driving member 111, movably connecting the input end of the second adapter 113 to the output end of the first adapter 112, and fixedly connecting the first abutting member 114 to the output end of the second adapter 113, the first driving member 111 drives the first adapter 112 to rotate vertically, and then drives the second adapter 113 to reciprocate along the preset direction, achieving the effect of driving the first abutting member 114 to reciprocate along the preset direction. There is no need for the driving direction of the first driving member 111 to be the preset direction. By changing the driving direction of the first driving member 111, the installation position of the first driving member 111 can be changed, so that the first driving member 111 is installed at the vacant position in the battery pressing device, improving the structural compactness of the horizontal clamping assembly 110 and saving the installation space.

[0068] Combined with Figures 3 to 6The specific transfer principle of the first transfer member 112 and the second transfer member 113 will be described. The first transfer member 112 includes a first transfer portion 1121, a second transfer portion 1122, and a pivot shaft 1123. Among them, the input end of the first transfer portion 1121 is rotatably connected to the output end of the first driving member 111. The first transfer portion 1121 can rotate vertically relative to the output end of the first driving member 111. The second transfer portion 1122 is fixedly connected to the first transfer portion 1121. A chute 1131 is formed at the input end of the second transfer member 113. The output end of the second transfer portion 1122 can slide in the chute 1131 and rotate vertically relative to the chute 1131. The pivot shaft 1123 is pivotally connected to both the first transfer portion 1121 and the second transfer portion 1122. The first transfer portion 1121 and the second transfer portion 1122 can rotate vertically along the pivot shaft 1123.

[0069] As Figure 5 and Figure 6 shown, taking the horizontal clamping assembly 110 on the left side of the battery as an example, when it is necessary to drive the first abutting member 114 to move to the right and abut against the battery, the first driving member 111 drives the first transfer portion 1121 and the second transfer portion 1122 to rotate clockwise around the pivot shaft 1123. At this time, the output end of the second transfer portion 1122 rotates in the chute 1131. Since the second transfer member 113 can only move in a preset direction (left - right direction) and cannot rotate around the pivot shaft 1123, the output end of the second transfer portion 1122 will drive the second transfer member 113 to move to the right, and the output end of the second transfer portion 1122 will slide from the upper end of the chute 1131 to the lower end of the chute 1131, thereby driving the first abutting member 114 to move to the right. When it is necessary to drive the first abutting member 114 to move to the left, the first driving member 111 drives the first transfer portion 1121 and the second transfer portion 1122 to rotate counterclockwise around the pivot shaft 1123. At this time, the output end of the second transfer portion 1122 rotates in the chute 1131. Since the second transfer member 113 can only move in a preset direction (left - right direction) and cannot rotate around the pivot shaft 1123, the output end of the second transfer portion 1122 will drive the second transfer member 113 to move to the left, and the output end of the second transfer portion 1122 will slide from the lower end of the chute 1131 to the upper end of the chute 1131, thereby driving the first abutting member 114 to move to the left.

[0070] To improve the movement accuracy of the second transfer member 113, a second guiding slider 1132 is provided on the second transfer member 113, and a first guiding slide rail 510 extending along the preset direction is provided on the frame 500. The second guiding slider 1132 is slidably engaged with the first guiding slide rail 510 on the frame 500 to provide guidance for the movement of the second transfer member 113, achieving the effect of improving the movement accuracy of the second transfer member 113.

[0071] As an alternative, the horizontal clamping assembly 110 further includes a first elastic buffer 115. One end of the first elastic buffer 115 is connected to the output end of the second adapter 113, and the other end of the first elastic buffer 115 is connected to the input end of the first abutting member 114. By providing the first elastic buffer 115 between the output end of the second adapter 113 and the input end of the first abutting member 114, when the output end of the first abutting member 114 abuts against the battery, if the first driving member 111 continues to operate, the second adapter 113 will continue to drive the first abutting member 114 to move towards the battery under the drive of the first driving member 111. At this time, the first elastic buffer 115 provided between the second adapter 113 and the first abutting member 114 can use its own elastic deformation to provide a buffer for the movement of the first abutting member 114, thereby improving the protection of the battery. It should be noted that, in this embodiment, the first elastic buffer 115 is a spring. The spring has a simple structure and is convenient for disassembly and assembly. In other embodiments, the first elastic buffer 115 can also be an elastic block made of an elastic material or other structures with elastic deformation, and this embodiment does not make specific limitations.

[0072] In this embodiment, to simplify the structure of the horizontal clamping mechanism 100, the first elastic buffer 115 is only provided in one horizontal clamping assembly 110, and the first elastic buffer 115 is not provided in the other horizontal clamping assembly 110. In other embodiments, the first elastic buffer 115 can also be provided in both horizontal clamping assemblies 110 at the same time, and this embodiment does not make specific limitations.

[0073] In an alternative embodiment, the vertical support mechanism 200 includes a second driving member 210 and a vertical support main body 220. The vertical support main body 220 is movably installed on the frame 500, and the vertical support main body 220 is connected to the output end of the second driving member 210. The second driving member 210 can drive the vertical support main body 220 to move in the vertical direction relative to the preset pressing position, and the vertical support main body 220 is used to support and position the installation jig 400. By installing the vertical support main body 220 on the frame 500 and connecting the vertical support main body 220 to the output end of the second driving member 210, the second driving member 210 drives the vertical support main body 220 to move in the vertical direction relative to the preset pressing position, realizing the vertical support of the vertical support main body 220 for the installation jig 400. The structure is simple and the support effect is good. It should be noted that, in this embodiment, the second driving member 210 is a linear cylinder. The linear cylinder has a simple structure, is sensitive in response, and has a stable output power. In other embodiments, the second driving member 210 can also be a linear motor or other linear driving structures, and this embodiment does not make specific limitations.

[0074] In this embodiment, as Figure 7As shown, the vertical support mechanism 200 supports the mounting jig 400 from the lower end of the mounting jig 400. A first docking protrusion 221 extending upward is provided on the upper end surface of the vertical support main body 220, and a second docking protrusion 410 extending downward is provided on the lower end surface of the mounting jig 400. The first docking protrusion 221 abuts against the second docking protrusion 410, and the support for the mounting jig 400 is realized by the abutment of the first docking protrusion 221 against the second docking protrusion 410.

[0075] To improve the docking accuracy between the first docking protrusion 221 and the second docking protrusion 410, as Figure 8 shown, a third guiding slider 222 is provided on the vertical support main body 220, and a second guiding slide rail 520 is provided on the frame 500. The second guiding slide rail 520 extends in the vertical direction, and the third guiding slider 222 is slidably engaged with the second guiding slide rail 520. By providing the third guiding slider 222 on the vertical support main body 220 and providing the second guiding slide rail 520 extending in the vertical direction on the frame 500, and making the third guiding slider 222 slidably engaged with the second guiding slide rail 520, when the second driving member 210 drives the vertical support main body 220 to move in the vertical direction, the third guiding slider 222 can slide along the second guiding slide rail 520, thereby providing guidance for the movement of the vertical support main body 220 in the vertical direction.

[0076] As an alternative solution, the pressing mechanism 300 includes a third driving member 310 and a pressing member 320.
