In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0025] See also Figure 1 and Figure 2The utility model provides a cell module leveling device, a conveyor belt 1 and a packaging device, including a leveling drive module 3, a cell tray 4 and a pole pressing plate 41. The pole pressing plate 41 is installed on both sides of the cell tray 4 along the first direction L1, and the leveling drive module 3 is symmetrically arranged on both sides of the pole pressing plate 41, and is used to drive the pole pressing plate 41 to move along the first direction L1 to level the cell module 2 placed on the cell tray 4.

[0026] In an exemplary embodiment, the pole pressing plate 41 is a strip-shaped plate structure. Specifically, the length of the pole pressing plate 41 is greater than or equal to the length of the battery cell module 2 , and the height of the pole pressing plate 41 is greater than or equal to the pole height of the battery cell module 2 .

[0027] The first direction L1 indicates the direction in which the pole pressing plate 41 moves from both sides of the cell tray 4 to the center of the cell tray 4 . The pole pressing plate 41 is used to squeeze the poles on both sides of the cell module 2 and level the cell module under the driving action of the leveling driving module 3 .

[0028] Preferably, the pole pressing plate 41 is perpendicular to the cell tray 4 and is arranged with a gap on both sides of the cell module 2 provided with poles, so that the installation space between the oppositely arranged pole pressing plates 41 is sufficient to accommodate the cell module 2. It should be noted that the pole pressing plate 41 is slidably installed on both sides of the cell tray 4 along the first direction L1, so that a moving space is provided when the leveling drive module 3 drives the pole pressing plate 41 to move toward the pole of the cell module 2.

[0029] In this embodiment, movable pole pressure plates 41 are symmetrically arranged on both sides of the battery tray 4 along the first direction L1, and cooperate with the leveling drive module 3. Under the push of the leveling drive module 3, the pole pressure plates 41 move toward the battery module 2 along the first direction L1. In this way, not only the leveling of the battery module placed on the battery tray 4 is achieved, but also the poles on both sides of the battery module can be flattened by the pole pressure plates 41 under the drive of the leveling drive module 3. The device has a simple structure, low cost, no manual operation is required, and the degree of automation is high.

[0030] A pressure plate connector 44 is provided on the battery cell tray 4, and a first mounting hole 411 extending along a third direction L3 is provided on the pole pressure plate 41, and the third direction L3 is perpendicular to the battery cell tray 4; the pressure plate connector 44 is accommodated in the first mounting hole 411, and the diameter of the pressure plate connector 44 is smaller than the aperture of the first mounting hole 411, and the first direction L1 and the third direction L3 are perpendicular to each other.

[0031] In an exemplary embodiment, the pressure plate connector 44 is disposed on the first surface along the third direction L3; the pressure plate connector 44 matches the first mounting hole 411, and each pressure plate connector 44 is respectively received in a corresponding first mounting hole 411. The pressure plate connector 44 may be integrally formed with the first surface of the cell tray 4, or may be detachably mounted on the first surface.

[0032] In one embodiment, the above-mentioned pressing plate connecting member 44 is a cylindrical guide rod, for example, the above-mentioned cylindrical guide rod is welded and fixed on the above-mentioned first surface, and is integrally formed with the first surface of the battery tray 4. The cylindrical guide rod is accommodated in the first mounting hole 411, and here, the diameter of the cylindrical guide rod is smaller than the diameter of the above-mentioned first mounting hole 411. Therefore, the above-mentioned cylindrical guide rod, that is, the pressing plate connecting member 44, is accommodated in the first mounting hole 411 with a gap, so that the pole pressing plate 41 can be driven by the leveling drive 3 to move along the first direction L1 on the first surface.

[0033] In another embodiment, the pressure plate connector 44 is detachably mounted on the first surface. A connector mounting hole is provided on the cell tray, and the connector mounting hole is used to mount the pressure plate connector 44. The pressure plate connector 44 may be any other connector such as a screw, and the present application does not limit the specific structure of the pressure plate connector 44. In an exemplary embodiment, the pressure plate connector 44 is a screw, and the first mounting hole 411 is a step hole. For example, the step hole includes a second mounting hole and a third mounting hole, and the aperture of the second mounting hole is greater than or equal to the aperture of the third mounting hole, and the aperture of the third through hole is greater than the diameter of the screw rod. An internal thread is provided in the connector mounting hole, and the screw is detachably mounted in the connector mounting hole, further realizing the detachable installation of the pole pressure plate 41 and the cell tray 4, and the nut portion of the screw is provided in the second mounting hole, and the diameter of the nut is greater than the diameter of the second mounting hole, so as to limit the pole pressure plate 41 in the third direction L3. The pole pressing plate 41 can be detachably mounted on the battery tray 4 so that the size of the pole pressing plate 41 can be adjusted according to the model of the battery module 2. The equipment has high flexibility and good adaptability, and the detachable installation is convenient for maintenance and replacement.

[0034] The surface of the battery cell tray 4 on which the pressure plate connector 44 is provided is the first surface, on which a pole pressure plate limit block 412 is provided, and the pole pressure plate 41 is provided with a limit block mounting groove, one end of the pole pressure plate limit block 412 is fixed on the battery cell tray 4, and the other end of the pole pressure plate limit block 412 is provided in the limit block mounting groove.

[0035] In an exemplary embodiment, the pole pressure plate 41 is detachably mounted on the battery tray 4 through the pole pressure plate stopper 412, and the pole pressure plate stopper 412 is also used to prevent the pole pressure plate 41 from moving in the third direction L3. Specifically, the pole pressure plate stopper 412 is a trapezoidal positioning block, which includes a first end and a second end, the cross section of the first end is larger than the cross section of the second end, the first end is slidably mounted in the stopper mounting groove, and the second end is fixed on the battery tray 4. Figure 4 As shown, the bottom width of the limit block installation groove is greater than the width at the slot opening. Therefore, when the trapezoidal positioning block is installed in the limit block installation groove, the pole pressure plate 41 can be limited in the vertical direction, and the pole pressure plate 41 can be moved toward the battery cell module 2 along the installation direction of the trapezoidal positioning block under the driving action of the leveling drive module 3, thereby realizing the movable function of the pole pressure plate 41 on the first surface, and the device structure is simple and the cost is low.

[0036] The leveling driving module 3 includes a first power device 31 and a first push rod 32 . One end of the first push rod 32 is connected to the first power device 31 , and the other end of the first push rod 32 abuts against the pole pressure plate 41 .

[0037] Specifically, the first power device 31 can be any one of other power devices such as a cylinder and a servo motor. In one embodiment, taking the first power device 31 as an example, the first power device 31 drives the first push rod 32 to move toward the pole pressure plate 41, so that the pole pressure plate 41 abuts against the battery cell module 2, and the first power device 31 continuously provides driving force to the first push rod 32 to drive the first push rod 32 to squeeze the pole of the battery cell module 2 toward the center of the battery cell tray 4 until the pole of the flattened battery cell module 2 is flattened, so as to achieve the effect of flattening the poles on both sides of the battery cell module while flattening the battery cell module placed on the battery cell tray 4, and the device has a simple structure, low cost, no manual operation, and a high degree of automation.

[0038] In another embodiment, the pole pressing plate 41 can also be directly fixedly mounted on one end of the first push rod 32 close to the battery module 2, and the pole pressing plate 41 is perpendicular to the battery tray 4. Taking the first power device 31 as an example, which is a servo motor, the first push rod 32 is connected to the servo motor, and driven by the servo motor, the pole pressing plate 41 is driven to move toward the battery module 2, thereby realizing the pole pressing plate 41 to squeeze the pole and level the battery module 2.

[0039] At least two first limit blocks 42 are provided on the cell tray 4 , and the at least two first limit blocks 42 are installed on both sides of the cell tray 4 along the second direction L2 . The at least two first limit blocks 42 cooperate with the pole pressure plate 41 to form the installation position of the cell module 2 .

[0040] Specifically, the first limit block 42 may be any structure such as a hexahedron, a cylinder, etc. The present application does not limit the specific shape of the first limit block 42. The first limit block 42 can limit the battery cell module 2 in the second direction L2.

[0041] Exemplarily, taking the first limit block 42 as a rectangular parallelepiped structure, two first limit blocks 42 are arranged on both sides of the second direction L2 of the battery tray. It should be noted that the installation position of the battery module 2 is formed between the first limit block 42 and the pole pressure plate 41, and the setting distance between the two first limit blocks 42 is greater than the length distance of the battery module 2 along the second direction L2. Therefore, the accommodation space of the battery module 2 formed between the first limit block 42 and the pole pressure plate 41 is greater than the volume of the battery module, making the installation of the battery module 2 more convenient and improving the tray loading efficiency.

[0042] The above-mentioned battery cell module leveling device also includes a battery cell clamping unit, which is arranged on the side of the first limit block away from the center of the battery cell tray 4. The battery cell clamping unit includes a clamping rack 45, a first mounting frame 46 and a second power device 47. The clamping rack 45 is arranged on the first mounting frame 46, and the first mounting frame 46 is slidably arranged on the second power device 47.

[0043] In an exemplary embodiment, the battery cell pressing unit is used to press the battery cell module 2. It should be noted that the pressing direction of the battery cell pressing unit on the battery cell module 2 is the second direction L2, and the pressing direction of the leveling drive module 3 on the battery cell module 2 is the first direction L1, and the first direction L1 and the second direction L2 are perpendicular to each other. Driven by the second power device 47, the first mounting frame 46 moves the pressing rack 45 to abut against the surface of the battery cell module 2, and the pressing rack 45 cooperates with the first limit block 42 away from the battery cell pressing unit to achieve the pressing of the battery cell module 2, thereby improving the leveling effect of the battery cell module 2 and facilitating the subsequent processing of the product.

[0044] The cell tray 4 is provided with a first installation slot for accommodating magnetic material, and the first installation slot is used to install the packing tape, which is adsorbed in the first installation slot by the magnetic material. Figure 3As shown, the first installation groove 43 is used to install the strapping tape to package the battery module 2. It should be noted that the magnetic material is a magnet, and the material of the strapping tape can be any material that can be adsorbed by a magnet, such as iron, nickel, cobalt, etc. Taking the strapping tape as steel as an example, a magnet is provided in the first installation groove 43 to strengthen the adsorption of the strapping tape, so that the installation of the strapping tape is more stable, which is convenient for the subsequent processing of the battery module 2.

[0045] According to one aspect of an embodiment of the utility model, a conveyor belt is provided. The conveyor belt 1 is applied to the above-mentioned battery cell module leveling device, and the battery cell tray 4 is placed on the conveyor belt 1 .

[0046] In an exemplary embodiment, the battery cell tray 4 is placed on a conveyor belt 1 for movement, and the leveling drive module 3 is fixedly installed on both sides of the conveyor belt 1. When the battery cell module 2 moves to the processing area of ​​the leveling drive module 3, the leveling drive module 3 starts to work.

[0047] According to one aspect of an embodiment of the utility model, a battery cell module packaging device is provided, comprising a guiding module, a tensioning module, a conveyor belt 1 and the above-mentioned battery cell module leveling device.

[0048] Working principle: The first surface of the battery tray 4 is provided with a plurality of pressure plate connectors 44 along the third direction L3 to match the first mounting hole 411 on the pole pressure plate. Specifically, the pressure plate connectors 44 are integrally formed and arranged on the first surface. The pole pressure plate 41 is detachably mounted on the battery tray 4 via the pole pressure plate limit block 412. Since the diameter of the pressure plate connector 44 is smaller than the aperture of the first mounting hole 411, the pole pressure plate 41 can be driven by the leveling drive module 3 to move toward the pole of the battery module 2 until it abuts against the surface of the battery module. Under the driving force of the leveling drive module 3, the pole pressure plate not only achieves the leveling of the battery module, but also achieves the effect of flattening the poles on both sides of the battery module. Figure 2 and Figure 5 As shown, the cell module leveling module is fixedly installed on both sides of the conveyor belt 1. When the cell module 2 moves to the cell module leveling module processing area, the leveling drive module 3 starts to work, and the first power device 31 drives the first push rod 32 to move toward the cell module 2, and then abuts against the pole pressing plate 41, thereby driving the pole pressing plate 41 to move toward the cell module 2, and realizing the leveling of the cell module pole.
