[0063] In some exemplary embodiments, Figure 1-Figure 3 As shown, a battery stacking device is used to assemble and stack batteries (not shown in the figure). The battery includes two liquid cooling plates and stacked battery cells, and the battery cells are arranged along a first horizontal direction (refer to Figure 1 X-axis shown) and / or a second horizontal direction (reference Figure 1 The two liquid cooling plates are arranged on opposite sides, such as on both sides of the plurality of battery cells along the first horizontal direction, and the two liquid cooling plates are respectively connected to the plurality of battery cells to achieve assembly.

[0064] The battery stacking device includes a frame 1, a carrying mechanism 2, a supporting mechanism 3, a hot pressing mechanism 4 and a first limiting mechanism 5. The frame 1 is provided with a channel 11 along the second horizontal direction to facilitate the accommodation and passage of the carrying mechanism 2. Multiple battery cells can be placed on the carrying mechanism 2 so that the carrying mechanism 2 can drive them to move and realize transportation.

[0065] The supporting mechanism 2 is detachably connected to the frame 1, so as to fix or remove the supporting mechanism 2. When pressurizing the supporting mechanism 2, it can effectively avoid the supporting mechanism 2 from being misplaced or moved, which affects the pressurization effect. The supporting mechanism 2 includes a supporting plate 21 to support multiple battery cells.

[0066] The support mechanism 3 is used to support the carrier plate 21 so as to limit the movement of the carrier plate 21 and ensure the corresponding connection between the liquid cooling plate and the battery cell.

[0067] The hot pressing mechanism 4 can drive the liquid cooling plate to move along the first horizontal direction, so as to pressurize the battery cell so that the liquid cooling plate and the battery cell can be connected together. The first horizontal direction and the extension direction of the channel 11 are perpendicular to each other.

[0068] The first limiting mechanism 5 is used to suppress the liquid cooling plate to avoid misalignment of the liquid cooling plate, further ensuring that the connection between the liquid cooling plate and the battery cell can be accurately aligned, thereby improving assembly accuracy.

[0069] Here, it should be noted that the above-mentioned support mechanism 3 can be, for example, four, and is separately arranged below the carrying plate 21. Specifically, it can be arranged near the four ends of the carrying plate 21, so as to provide a balanced and stable support force for the carrying plate 21 and prevent the carrying plate 21 from tilting. Of course, the support mechanism 3 is not limited to four, and the specific situation shall prevail.

[0070] In addition, the heat pressing mechanism 4 may be, for example, two, arranged along the first horizontal direction on both sides of the battery cell, so as to pressurize and heat the liquid cooling plate, and realize the setting of the liquid cooling plate on the side of the battery cell. For example, two first limiting mechanisms 5 are arranged in each heat pressing mechanism 4, and are arranged along the second horizontal direction on both sides of the liquid cooling plate, so as to press down and fix the two ends of the liquid cooling plate respectively, and improve the stability of the liquid cooling plate.

[0071] In some exemplary embodiments, Figure 1 , Figure 5 , Figure 6 As shown, the hot pressing mechanism 4 includes a hot pressing support frame 41 , a hot pressing member 42 and a hot pressing driving unit 43 .

[0072] The hot pressing member 42 is, for example, disposed on the side of the hot pressing support frame 41, and the liquid cooling plate is disposed in close contact with the hot pressing member 42 to facilitate application of pressure. The hot pressing driving unit 43 drives the hot pressing member 42 to move along the first horizontal direction through the hot pressing support frame 41.

[0073] The hot pressing driving unit 43 may be, for example, one, located in the middle of the hot pressing support frame 41, so as to apply pressure to the battery cell. Two hot pressing driving units 43 may be provided, for example, on both sides along the second horizontal direction, so as to ensure that the hot pressing mechanism 4 can apply balanced pressure to the liquid cooling plate.

[0074] The hot pressing part 42 is, for example, a heating resistance wire, which is placed in a receiving box and is energized with an external device through a wire. The hot pressing support frame 41 is provided with a receiving groove 414, and the hot pressing part 42 is received in the receiving groove 414 to ensure the flatness of the appearance. The outer surface of the hot pressing part 42 is flush with the edge of the receiving groove 414, so that the hot pressing part 42 can pressurize and heat the liquid cooling plate.

[0075] Some examples include Figure 5 As shown, the hot pressing support frame 41 includes, for example, a first hot pressing support frame 411 and a second hot pressing support frame 412. The second hot pressing support frame 412 is arranged above the first hot pressing support frame 411. The hot pressing driving unit 43 is installed on the first hot pressing support frame 411. The driving shaft of the hot pressing driving unit 43 drives the second hot pressing support frame 412 to move along the first horizontal direction to facilitate squeezing the battery cell or moving away from the battery cell.

[0076] The hot pressing driving part 43 is, for example, a driving motor, and a driving shaft of the driving motor is connected to the hot pressing supporting frame 41 to drive the hot pressing supporting frame 41 to move.

[0077] In addition, a heating support slide rail 413 may be provided between the first hot pressing bracket 411 and the second hot pressing bracket 412, and the second hot pressing bracket 412 is slidably connected to the first hot pressing bracket 411 through the heating support slide rail 413. For example, there may be two heating support slide rails 413, which can not only provide support for the second hot pressing bracket 412, but also limit the movement direction of the second hot pressing bracket 412 to ensure that the liquid cooling plate and the battery cell can be connected in position.

[0078] In this embodiment, if Figure 1 , Figure 5 , Figure 6 As shown, the hot pressing mechanism 4 further includes a pressure monitoring component 44 disposed on the hot pressing driving part 43 to monitor the pressurizing state of the hot pressing mechanism 4 .

[0079] The pressure monitoring component 44 is, for example, a pressure sensor 441 and a mounting plate 442. The mounting plate 442 is connected to the hot pressing drive unit 43. The pressure sensor 441 is installed and fixedly connected to the mounting plate 442. The mounting plate 442 is connected to the second hot pressing bracket 412, so that when the hot pressing mechanism 4 applies pressure, the pressure sensor 441 can monitor the pressure value to provide a suitable pressure value for the liquid cooling plate and the battery cell. Among them, the pressure value has a preset pressure value. When the preset pressure value is reached, the hot pressing drive unit 43 stops running, and the hot pressing component 42 starts to heat the liquid cooling plate, so that the glue on the liquid cooling plate slowly solidifies, and the liquid cooling plate and the battery cell are glued together. When the glue is formed and starts to stand still, the hot pressing component 42 stops heating after the standing still is completed.

[0080] The mounting plate 442 may also be slidably connected to the first hot pressing bracket 411 via a limiting slide rail 443, for example, to ensure that the mounting plate 442 can move along the first horizontal direction, and the liquid cooling plate and the battery cell can be precisely aligned.

[0081] In some exemplary embodiments, Figure 1 , Figure 5-Figure 7 As shown, the first limiting mechanism 5 includes a first limiting mounting bracket 51 , a first limiting driving portion 52 and a rotating pressing block 53 .

[0082] The first position-limiting mounting bracket 51 is disposed on the hot pressing support frame 41 of the hot pressing mechanism 4 , and the first position-limiting driving part 52 and the rotating pressing block 53 are respectively disposed on the first position-limiting mounting bracket 51 .

[0083] The first limit driving part 52 is, for example, a cylinder, a cylinder body of which is fixedly connected to the hot pressing support frame 41 , and a driving shaft of which is fixedly connected to the rotating pressing block 53 .

[0084] In some examples, the driving shaft of the first position limiting driving part 52 can drive the rotating pressing block 53 to move vertically. When moving upward, the liquid cooling plate can be placed conveniently, and when moving downward, the liquid cooling plate can be pressed.

[0085] In other examples, the driving shaft of the first limit driving unit 52 can drive the rotating pressing block 53 to rotate in the horizontal direction to stagger the position of the liquid cooling plate. When the liquid cooling plate is placed, the rotating pressing block 53 can be driven to rotate to the top of the liquid cooling plate to press it.

[0086] Of course, it is understandable that the driving shaft of the first limit driving part 52 can drive the rotating block 53 to rotate horizontally or move vertically, so that the first limit mechanism 5 is more flexible and can meet different scenarios or requirements of the liquid cooling plate.

[0087] The rotating pressing block 53 may be, for example but not limited to, an inverted L shape, so as to extend the pressing portion and improve the pressing effect.

[0088] In this embodiment, if Figure 1 , Figure 5-Figure 7 As shown, the first position limiting mechanism 5 further includes a slide rail 54, and the first position limiting mounting bracket 51 is slidably connected to the hot pressing support frame 41 of the hot pressing mechanism 4 through the slide rail 54, so as to adjust the position of the first position limiting mechanism 5. The slide rail 54 extends along the second horizontal direction, and adjusts the position of the first position limiting mechanism 5 on both sides of the hot pressing mechanism 4 to ensure that the first position limiting mechanism 5 can press the liquid cooling plate.

[0089] The slide rail 54 may be provided with a driving cylinder 541 , for example. The driving cylinder 541 is connected to the first position-limiting mounting bracket 51 , so as to drive the first position-limiting mounting bracket 51 to move on the slide rail 54 , thereby realizing automatic control and improving precision.

[0090] The first limiting mechanism 5 includes a liquid cooling support plate 55 disposed on the first limiting mounting bracket 51, and the liquid cooling plate is placed on the liquid cooling support plate 55 to provide support for the liquid cooling plate. The liquid cooling support plate 55 protrudes from the hot pressing support frame 41 along the first horizontal direction so that the liquid cooling plate can be placed.

[0091] The liquid cooling support plate 55 is provided with a limit stopper 551, which is located on the side of the liquid cooling support plate 55 away from the hot pressing mechanism 4, and is used to limit the movement of the liquid cooling plate along the second horizontal direction, which is the same as the extension direction of the channel 11. The limit stopper 551 is, for example, an L-shaped corner stopper, so as to clamp the liquid cooling plate and limit it in both the first horizontal direction and the second horizontal direction.

[0092] In some exemplary embodiments, Figure 1 , Figure 3 , Figure 4 As shown, the supporting mechanism 3 includes a lifting member 31 and a supporting member 32 .

[0093] The lifting member 31 can drive the bearing plate 21 to move in the vertical direction (refer to Figure 1 The support member 32 is used to support the lifting member 31 and provide a double supporting force for the bearing plate 21 to ensure the balance of the bearing plate 21.

[0094] In some examples, the lifting member 31 includes a lifting drive unit 311 and a lifting platform 312 . The lifting drive unit 311 is disposed on the frame 1 . The lifting drive unit 311 is connected to the lifting platform 312 to drive the lifting platform 312 to move in a vertical direction.

[0095] The lifting drive part 311 is, for example, an electric cylinder, which is placed vertically, and the cylinder body is fixedly connected to the frame 1. Its driving shaft passes through the frame 1 and is connected to the lifting platform 312 to drive the lifting platform 312 to move in the vertical direction.

[0096] The lifting platform 312 is located below the carrying plate 21 . When the carrying mechanism 2 is placed at a target position, the lifting driving unit 311 drives the lifting platform 312 to lift up to support the carrying plate 21 .

[0097] In order to ensure that the supporting plate 21 is placed in place, the lifting platform 312 can be provided with a limit pin 3121, and the supporting plate 21 can be provided with a limit pin hole 211, and the limit pin 3121 is plugged into the limit pin hole 211 to ensure that the lifting platform 312 will not be misplaced.

[0098] In this embodiment, if Figure 1 , Figure 3 , Figure 4 As shown, the support member 32 includes a support block 321 and a support driving part 322. The support driving part 322 drives the support block 321 to move along the second horizontal direction. The support block 321 is used to support the lifting platform 312. The support driving part 322 is, for example, a driving cylinder, and in order to ensure that the support block 321 moves along the second horizontal direction, the support block 321 can be slidably connected to the frame 1 through a support slide rail 323, and the support slide rail 323 extends along the second horizontal direction.

[0099] In order to ensure the support balance, two support members 32 can be provided, for example, and the two support members 32 are arranged on both sides of the lifting member 31 along the second horizontal direction, so as to provide support force for both ends of the lifting member 31 and ensure the balance of the lifting member 31.

[0100] In the initial state, the support block 321 is away from the lifting member 31 to avoid the lifting member 31 and provide it with movement space. The lifting driving part 311 of the lifting member 31 drives the lifting platform 312 to lift the supporting plate 21, and the support driving part 322 drives the support block 321 to approach the lifting member 31 and move to the bottom of the lifting platform 312. The lifting driving part 311 of the lifting member 31 drives the lifting platform 312 to move downward, so that the lifting platform 312 can be placed on the support block 321 to provide a balanced and stable supporting force for the supporting plate 21.

[0101] In some exemplary embodiments, Figure 1 , Figure 3 As shown, the bearing mechanism 2 includes, for example, a bearing support frame 22 , which is movably disposed in the channel 11 , and the bearing plate 21 is disposed on the bearing support frame 22 , and the bearing support frame 22 can provide support for the bearing plate 21 .

[0102] The load-bearing support frame 22 can be moved to facilitate the transportation of the battery cells. For example, a plurality of universal wheels are arranged below the load-bearing support frame 22, such as the first universal wheel 221 with self-locking function, so that the battery cells can be transported without any effort and can be locked at any time to prevent them from moving.

[0103] In this embodiment, if Figure 1-Figure 3 As shown, in order to ensure the stability of the bearing support frame 22, the liquid cooling plate and the battery cell can be connected in alignment, and the bearing support frame 22 can also be provided with a limit socket 251, and the rack 1 is provided with a plug-in portion 12, and the plug-in portion 12 and the limit socket 251 are plugged to ensure that the bearing mechanism 2 will not be misaligned or moved, and further improve the alignment accuracy between the liquid cooling plate and the battery cell. Among them, the limit socket 251 can be set on the limit block 25, for example, the limit block 25 is installed on the bearing support frame 22, and the limit socket 251 is formed on the limit block 25.

[0104] The plug-in portion 12 may be, for example, a cylinder, the cylinder body of which is fixedly connected to the bearing support frame 22, and the telescopic rod of which may be plugged into or out of the limiting plug hole 251. When plugging is not required, the telescopic rod of the plug-in portion 12 may be retracted to avoid collision with the outside during transportation.

[0105] The rack 1 may also be provided with an abutment portion 13, which may be a cylinder, whose cylinder body is fixedly connected to the rack 1, and the telescopic rod of the abutment portion 13 abuts against the side of the bearing support frame 22, further resisting the movement of the bearing support frame 22 to ensure the stability of the bearing mechanism 2 and prevent it from shaking or misalignment. The plug-in portion 12 and the abutment portion 13 double limit the movement of the bearing support frame 22, further ensuring the stability of the bearing mechanism 2, thereby achieving precise alignment of the liquid cooling plate and the battery cell.

[0106] In this embodiment, if Figure 1-Figure 3 As shown, the frame 1 is provided with a roller bracket 14 and a plurality of rollers 15 rotatably arranged on the roller bracket 14, and the rollers 15 are in contact with the side of the bearing support frame 22.

[0107] When the carrying mechanism 2 moves along the channel 11, the roller 15 can abut against the carrying support frame 22 to limit the movement direction of the carrying mechanism 2. The roller 15 can also reduce the friction between the carrying support frame 22, avoid wear of the carrying support frame 22, and extend the service life of the carrying support frame 22.

[0108] In this embodiment, if Figure 1 , Figure 3 As shown, the carrying mechanism 2 may further include a cell placement platform 23 , and the cell placement platform 23 may be slidably disposed on the carrying plate 21 .

[0110] Of course, it is understandable that the supporting mechanism 2 is not limited to the above structure, and a pressure sensor may be provided but not limited to monitor the pressure value when the battery cells are stacked; or, a plurality of rings 212 are provided on the upper surface of the supporting plate 21 so that external equipment can grasp the supporting plate 21 through the rings 212. The specific structure shall be subject to the actual situation.

[0111] In some exemplary embodiments, Figure 1 , Figure 8 As shown, the battery stacking device includes a second position limiting driving unit 6, which is located above the battery cells and is used to press the battery cells so that the multiple battery cells become flatter.

[0112] The second position-limiting driving part 6 includes a second position-limiting mounting bracket 61, a second position-limiting driving part 62 and a position-limiting member 63. The second position-limiting mounting bracket 61 is arranged on the frame 1, and the second position-limiting mounting bracket 61 is, for example, slidably arranged on the frame 1, so as to adjust the position of the second position-limiting driving part 6 to ensure that the second position-limiting driving part 6 can be aligned with the battery cell. Among them, the second position-limiting mounting bracket 61 can, for example, realize the sliding and limiting of the second position-limiting mounting bracket 61 by pressing down the slide rail 611 and the position-limiting chain 612, and the pressing down the slide rail 611, for example, extends along the first horizontal direction.

[0113] The second limit driving part 62 is installed on the second limit mounting bracket 61. The second limit driving part 62 is, for example, a cylinder, which is placed vertically. The driving shaft of the second limit driving part 62 can drive the limit member 63 to move in the vertical direction to facilitate pressing the battery cell.

[0114] In this embodiment, if Figure 1 , Figure 8 As shown, the limiting member 63 includes a suspension bracket 631 and a plurality of lower pressing rollers 632, and the plurality of lower pressing rollers 632 are installed on the suspension bracket 631. The second limiting driving unit 62 is connected to the suspension bracket 631 to drive the suspension bracket 631 to move in a vertical direction so that the lower pressing rollers 632 press the battery cells or withdraw from the battery cells.

[0115] The lower pressing roller 632 has a smooth curved surface, which can avoid damaging the surface of the battery cell, improve the safety during pressing, and effectively reduce the defective rate of the battery.

[0116] like Figure 1 , Figure 2 As shown, the battery stacking device also includes at least one of the following: a control unit 7, a universal wheel, and a support column. The control unit 7 is arranged on the frame 1 to control and monitor the battery stacking device. The control unit 7 includes, for example, a display screen 71 and a control box 72 to realize the automation of the battery stacking device.

[0117] Universal wheels, for example, can be provided on the frame 1 and / or the supporting mechanism 2. The supporting mechanism 2 has been described in detail above and will not be described again here. The frame 1, for example, is provided with a plurality of supporting universal wheels 16 to facilitate pushing the frame 1. In addition, the frame 1 can also be provided with a plurality of supporting columns 17. The supporting columns 17 can, for example, be provided at the bottom, side, etc. of the frame 1, and are all connected to the ground to facilitate supporting the entire frame 1 and prevent the frame 1 from being unstable and moving. The specific number and setting position shall be subject to the actual situation.

[0118] The battery stacking equipment proposed in this application uses a hot pressing mechanism to heat the glue on the liquid cooling plate on one side, which effectively improves the heating effect and makes the heating efficiency faster. The hot pressing mechanism extrude the battery cell and the liquid cooling plate in two directions. Different pressures can be controlled at different distances, and the application range is wider. The pressure state is monitored by a pressure monitoring device, which has a high degree of automation and realizes the battery stacking heating molding process.

[0119] The lifting member can ensure that the carrier plate is positioned in the center, and the first limiting mechanism presses the liquid cooling plate tightly, so that the assembly accuracy of the liquid cooling plate and the battery cell is higher.
