[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0056] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0057] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0058] In order to solve the technical problems in the prior art of low efficiency and inability to position and assemble end plates and battery cells, which affects product quality, the present application provides a battery cell packaging device that can position and place end plates, pre-embed steel belts, and directly attach steel belts to bind battery cell modules during pre-pressing, thereby improving product quality and efficiency.

[0061] In some exemplary embodiments, a battery cell packaging device is used to package a plurality of stacked battery cells, and bind the battery cells and end plates together through steel belts.

[0062] like Figure 1 , Figure 5 , Figure 6 As shown, the battery cell packaging device includes a platform 1, a supporting mechanism 2, two pressure members 3 and two end plate fixing members 4.

[0063] The carrying mechanism 2 is slidably disposed on the platform 1, and includes a carrying bracket 21 and a plurality of clamping portions 22. The carrying bracket 21 is used to carry a plurality of battery cells and provide a support position and a packaging position for the battery cells. The carrying bracket 21 is, for example, a rectangular bracket structure, and a pad platform 211 is disposed on the top to facilitate the placement of the battery cells.

[0064] A plurality of clamping portions 22 are arranged along the circumference of the support bracket 21 and are fixedly connected to the support bracket 21. The support bracket 21 is arranged along the first horizontal direction (refer to Figure 1 The X-axis shown in FIG. 1 has a first side and a second horizontal direction (refer to FIG. Figure 1 The Y-axis shown in the figure has a second side, and the first side and the second side can both be provided with a clamping portion 22.

[0065] The clamping part 22 is used to clamp the steel belt A, so that the steel belt A can be pre-buried in advance for subsequent quick binding. The first side and the second side can each be provided with at least two clamping parts 22, and the clamping parts 22 are provided near the corner ends of the bearing bracket 21 to prop open the steel belt A and ensure that the steel belt A can form a regular loop for easy binding.

[0066] Two end plate fixing members 4 are arranged on both sides of the supporting mechanism 2 along the first horizontal direction, and the end plate fixing members 4 are used to fix the end plate B. The end plate fixing members 4 are connected to the corresponding pressure members 3 .

[0067] One of the pressure members 3 is movable, and the other pressure member 3 can be fixed. One of the pressure members 3 can drive the corresponding end plate fixing member 4 to move and squeeze multiple battery cells so that they abut against the end plate fixing member 4 on the other pressure member 3. The multiple battery cells become compact and flat through squeezing. When one of the pressure members 3 squeezes the battery cells, the other pressure member 3 can provide resistance for it, further ensuring that the multiple battery cells are compressed.

[0068] The end plate B is connected to the adjacent battery cell (not shown in the figure), and the steel strip A can bind the end plate B and the battery cell together to complete the packaging.

[0069] In some exemplary embodiments, Figure 1-Figure 4 As shown, one of the end plate fixing members 4 is connected to the movable pressure member 3 and moves with it, and the other end plate fixing member 4 is connected to the fixed pressure member 3 .

[0070] The end plate fixing member 4 includes a mounting base plate 41, a fixing portion 42 and a positioning portion 43. The mounting base plate 41 is connected to the pressure member 3, and one of the pressure members 3 drives the corresponding mounting base plate 41 to move. The mounting base plate 41 can be fixedly connected to the pressure member 3 through a bearing 411, for example, to achieve assembly.

[0071] In order to improve the stability during installation, the mounting substrate 41 can also be connected to the pressure member 3 through a plurality of connectors 412. The connectors 412 are arranged along the circumference of the bearing 411, so that the connection between the mounting substrate 41 and the pressure member 3 is more reliable.

[0072] The connecting member 412 can be, for example, a compression spring with a certain resilience. When the mounting substrate 41 is connected to the pressure member 3 through the bearing 411, there will be an installation gap, which will make the connection between the mounting substrate 41 and the pressure member 3 unreliable, and the end plate fixing member 4 will tend to fall due to its own gravity. Therefore, the connection member 412 is provided to make the connection between the mounting substrate 41 and the pressure member 3 more reliable, and the connecting member 412 uses a compression spring to resist its slight misalignment or deformation. When the extrusion is finished, the connecting member 412 can restore it to its original state.

[0073] The fixing portion 42 is mounted on the mounting substrate 41 , and the fixing portion 42 is used to fix the end plate B so as to drive the fixed end plate B to move closer to the battery cell.

[0074] Some examples include Figure 3 , Figure 4As shown, the fixing part 42 includes, for example, a fixing base plate 421 and a plurality of suction cups 422. The fixing base plate 421 is provided with a plurality of mounting through holes 4211, and the suction cups 422 are embedded in the corresponding mounting through holes 4211. The first side of the end plate B in contact with the battery cell is a plane, and the other side of the end plate B connected with the suction cup 422 is a special-shaped surface. The fixing base plate 421 can be provided with a plurality of avoidance holes 4212, which can not only avoid the special-shaped part of the end plate B to play a role in positioning and limiting, but also the special-shaped part can be correspondingly plugged into the avoidance hole 4212.

[0075] Of course, it is understandable that the shape of the above-mentioned special-shaped surface shall be based on the actual situation. Here, no specific limitation is made on its shape. The shape and number of the avoidance holes 4212 may correspond to the special-shaped part.

[0076] In other examples, the fixing portion 42 may be a clamp (not shown in the figure) to clamp the end plate B. Alternatively, the fixing portion 42 may be a magnet to attract the end plate B, which depends on the actual situation.

[0077] In this embodiment, if Figure 3 , Figure 4 As shown, the positioning portion 43 is disposed on the side of the mounting substrate 41 to position the end plate B. Exemplarily, the positioning portion 43 includes a limit reference plate 431 and a first detection member 432, which are disposed on opposite sides of the mounting substrate 41 along the second horizontal direction.

[0078] The limit reference plate 431 is fixedly connected to the mounting base plate 41, and part of the structure protrudes from the surface of the mounting base plate 41. The limit reference plate 431 provides a positioning reference for the end plate B. When the end plate B is placed, the end plate B can be against the limit reference plate 431 to limit and position the end plate B.

[0079] The first detection member 432 is, for example, a first sensing element, which is, for example, a sensor or an image acquisition device, for detecting the presence of the end plate B and determining the position of the end plate B, so as to judge whether the end plate B is in place.

[0080] In this embodiment, if Figure 3 As shown, the battery packing device further includes a first limiting track 44. The mounting base plate 41 of one of the end plate fixing members 4 is slidably connected to the first limiting track 44 to achieve limiting movement.

[0081] Since the end plate fixing member 4 is connected to the pressure member 3 through the connecting member 412, the end plate fixing member 4 will fall downward due to its own weight, which will affect the installation accuracy and extrusion effect of the entire end plate fixing member 4 over time. The mounting substrate 41 is slidably arranged on the first limiting track 44, which can not only provide a limit for the end plate fixing member 4, but also further support the end plate fixing member 4 to prevent it from falling. Among them, the mounting substrate 41 can be directly slidably connected to the first limiting track 44, or it can be slidably connected to the first limiting track 44 through the connecting bracket 413.

[0082] In some exemplary embodiments, Figure 1 , Figure 2 As shown, the pressure member 3 includes, for example, a pressure plate 31, a pressure plate support frame 35 and a pressure sensor (not shown in the figure). The pressure plate 31 is fixedly mounted on the pressure plate support frame 35 to support the pressure plate 31. The pressure sensor is used to monitor the pressure value when the pressure member 3 pushes the battery cell to avoid excessive squeezing force and damage to the battery cell. The fixed pressure member 3 can be directly fixedly connected to the platform 1 through the pressure plate support frame 35, and the movably arranged pressure member 3 can be driven by an external force. For example, the packaging equipment for the battery cell also includes a first drive unit 32 and a first chain 33, and the first drive unit 32 and the first chain 33 are respectively mounted on the platform 1.

[0083] In some examples, the first driving part 32 is, for example, an electric cylinder, whose cylinder body is installed on the platform 1 through a driving support frame 321, and the piston rod of the electric cylinder passes through the driving support frame 321 and is connected to a pressure plate support frame 35 of one of the pressure members 3, so as to drive its pressure plate 31 to move along the first direction.

[0084] In other examples, the first driving part 32 can also be a motor (not shown in the figure), and its motor housing is installed on the platform 1 through the driving support frame 321, and the driving shaft of the motor rotates through the driving support frame 321 and is connected to the pressure plate support frame 35.

[0085] Among them, in order to ensure that the pressure plate 31 makes linear motion along the first direction, a screw (not shown in the figure) is arranged between the pressure plate support frame 35 and the driving support frame 321, one end of the screw is fixedly connected to the driving support frame 321, and the pressure plate support frame 35 is provided with a mounting hole, and the other end of the screw is movably connected to the pressure plate support frame 35 through the mounting hole.

[0086] The pressure plate support frame 35 of one of the pressure members 3 is connected to the first driving part 32 and the first chain 33 respectively. The first driving part 32 drives the pressure plate support frame 35 of the pressure member 3 to move along the first horizontal direction, and the pressure plate support frame 35 drives the pressure plate 31 to move. The first driving part 32 is located on the side of the pressure member 3 away from the end plate fixing member 4, so as to squeeze multiple battery cells onto the other end plate fixing member 4.

[0087] In this implementation, if Figure 1 , Figure 2 As shown, the battery packing device further includes at least one second limiting track 34. For example, two second limiting tracks 34 may be provided and are arranged on both sides of the first limiting track 44 along the second horizontal direction.

[0088] The second limiting rail 34 is installed on the platform 1, and a pressure plate support frame 35 of a pressure member 3 is slidably connected to the second limiting rail 34. The second limiting rail 34 can not only limit the pressure plate support frame 35, but also support the pressure plate support frame 35 to prevent it from falling due to its own gravity and being difficult to move.

[0089] In some exemplary embodiments, Figure 1 , Figure 5 As shown, the battery packing device also includes two side pressure members 5, which are arranged on both sides of the supporting mechanism 2 along the second horizontal direction to provide the battery cells with position limits in the second horizontal direction. Multiple battery cells are placed on the pad platform 211 of the supporting mechanism 2. During the placement process, multiple battery cells will appear uneven, which can be corrected by the side pressure members 5. For example, one of the side pressure members 5 can move relative to the supporting mechanism 2 and push all the battery cells to the other side pressure member 5, so that the multiple battery cells become flat and easy to bind.

[0090] The side pressure member 5 includes, for example, a side pressure plate 51 and a side pressure plate bracket 52. The side pressure plate 51 is connected to the bearing mechanism 2 via the side pressure plate bracket 52. The side pressure plate bracket 52 provides support for the side pressure plate 51, and the side pressure plate bracket 52 is used to squeeze the battery cells so that the multiple battery cells become flat.

[0091] Here, it should be noted that only one side pressure member 5 is shown in the figure, and the side pressure member 5 is movable, and the other side pressure member 5 that is fixed is not drawn. The other side pressure member 5 is arranged on the opposite side of the movable side pressure member 5 and is fixedly connected to the supporting mechanism 2 to limit the battery cell.

[0092] In this embodiment, if Figure 1 , Figure 5 , Figure 8 As shown, in order to realize automation during extrusion and reduce manual labor, the battery cell packaging equipment also includes a second driving unit 53.

[0093] The second driving part 53 is, for example, an electric cylinder, and the cylinder body 531 of the second driving part 53 is arranged on the supporting bracket 21. The piston end 532 of the second driving part 53 is connected to the side pressure plate bracket 52 of one of the side pressure members 5 to drive one of the side pressure members 5 to move relative to the supporting mechanism 2, so that one of the side pressure members 5 can push the battery cell on the supporting mechanism 2 to the other side pressure member 5.

[0094] In this embodiment, if Figure 1 , Figure 5 As shown, the battery packing device further includes a third limiting rail 54 installed on the carrying mechanism 2, and the third limiting rail 54 is installed in the carrying bracket 21, and a side pressure plate bracket 52 of one side pressure member 5 is slidably connected to the third limiting rail 54 to further limit the moving direction of the side pressure plate bracket 52. For example, the side pressure plate bracket 52 is slidably connected to the third limiting rail 54 through a guide block 521.

[0095] In an exemplary embodiment, Figure 1 , Figure 5 As shown, the battery packing device further includes a third driving unit 6 installed on the platform 1. The third driving unit 6 is arranged at another pressure member 3, and the third driving unit 6 is, for example, an electric cylinder, and the third driving unit 6 can push the supporting mechanism 2 to move along the first horizontal direction to provide a place for removing the packaged battery cells.

[0096] In this embodiment, if Figure 1 , Figure 5 As shown, the battery cell packaging equipment also includes a fourth limiting rail 7 installed on the platform. The supporting mechanism 2 is slidably connected to the platform 1 through the fourth limiting rail 7 to limit the movement direction of the supporting mechanism 2 to ensure that the supporting mechanism 2 moves linearly.

[0097] In this embodiment, if Figure 1 , Figure 5-Figure 7 As shown, the supporting mechanism 2 includes a second detection member 23. The second detection member 23 can be one to detect the battery cells on the supporting bracket 21; or, the second detection member 23 can be multiple to detect different positions of the battery cells to further improve the detection results.

[0098] The second detection member 23 , for example, can be disposed on the support bracket 21 , and is used to detect the position of the battery cell. The second detection member 23 , for example, includes two first-type sensors 231 and two second-type sensors 232 .

[0099] Two first-type sensors 231 are located at both ends of the pad platform 211 along the first horizontal direction. The first-type sensor 231 is, for example, a reflective sensor, and the sensing part of the reflective sensor is a triangle. The tip of the triangle is used for the reflected sensing distance, which is used to sense whether there is a battery cell on the pad platform 211.

[0100] Two second-type sensors 232 are located at two ends of the pad platform 211 along the second horizontal direction. The second-type sensors 232 are used to sense whether there are battery cells on the pad platform 211 .

[0101] The first type of sensor 231 and the second type of sensor 232 are located in front, back, left and right of the pad platform 211 to determine whether the battery cells are placed in place to avoid deviation during placement.

[0102] In an exemplary embodiment, Figure 1 , Figure 5 , Figure 7 As shown, the clamping portion 22 includes a first baffle 221 and a second baffle 222. The first baffle 221 and the second baffle 222 are arranged at intervals, and the steel strip A is clamped between the first baffle 221 and the second baffle 222 to limit the position of the steel strip A.

[0103] In this embodiment, if Figure 1 , Figure 5 As shown, the battery packing device also includes a driving motor 8 and a driving gear 9. The housing of the driving motor 8 is fixedly connected to the platform 1 through a motor bracket 81, and the driving motor 8 is placed upside down. A through hole 11 is provided on the platform 1. The output shaft of the driving motor 8 rotates through the through hole 11 of the platform 1 and is connected to the driving gear 9. The driving gear 9 is connected to an external device. The driving motor 8 can drive the entire platform 1 to rotate through the driving gear 9 to rotate it to the target position.

[0104] The battery packing equipment proposed in this application is simple and easy to debug, and includes a bearing mechanism, a pressure member, an end plate fixing member, and a side pressure member. Among them, the end plate fixing member can position and install the end plate, and a manipulator or robot places a single row of battery cells on the pad platform, and the pressure member pre-presses it, and the side pressure member flattens the side of the battery cell to facilitate the insertion of the steel belt and bind the battery cell and the end plate.

[0105] Among them, the steel belt is pre-buried and quickly positioned and installed through the clamping part, and inserted into the battery cell and end plate from the bottom to the top, realizing rapid installation, improving the production efficiency of the machine, improving quality, and reducing safety risks. When the binding is completed, the movable pressurizing part withdraws from the platform, and the third drive unit pushes the platform to expand the operating space, and the packaged battery cell is removed by the aerial crane.
