For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0050] Figure 1 , Figure 2 A preferred embodiment of the present invention is given; see Figure 1 , Figure 2 A soft-pack battery cell processing line includes a battery cell carrier 2, a conveying mechanism 1, and a cutting and bending mechanism, a dog-ear folding mechanism 5, and a foam mounting mechanism which are sequentially arranged along the conveying direction of the conveying mechanism 1; the battery cell carrier 2 is used to carry a battery cell 6, and the conveying mechanism 1 is used to transport the battery cell carrier 2 to the processing mechanism along the line to improve the production and processing efficiency of the entire line; the cutting and bending mechanism is used to cut the battery cell pole ear to a fixed length and bend it 90 degrees, and the purpose of the 90-degree bending is to prevent the battery cell from interfering with the bracket; the dog-ear folding mechanism 5 is used to fold the dog ears of the battery cell 6, and the foam mounting mechanism is used to perform foam mounting on the battery cell 6, thereby completing the automation of the pre-processing process of the soft-pack battery cell.

[0051] Specifically, the conveying mechanism 1 is preferably a magnetic suspension line. The magnetic suspension line has the characteristics of high speed and high precision. Its moving speed is three times that of the traditional step-feeding line, so that under the same production rhythm, the stations of each processing mechanism can be reduced by at least half, and the length of the entire line machine can be shortened by at least half, which greatly reduces the cost. Under the same output of 20PPM, the length of the traditional step-feeding line needs to be 8.2 meters, while the length of the entire line is shortened to 4.7 meters after magnetic suspension. The spacing between each processing station of the entire magnetic suspension line is 300mm; conveying mechanism 1 is divided into two layers, the upper layer is the working layer, and the lower layer is the carrier return layer. A loading mechanism 11 and a unloading mechanism 18 are respectively arranged at the line head and the line tail. The loading mechanism 11 is used to lift the battery carrier 2 from the carrier return layer to the working layer. The loading mechanism 11 transports two battery carriers 2 to the magnetic suspension line at a time. The unloading mechanism layer is used to lower the battery carrier 2 from the working layer to the carrier return layer. The unloading mechanism 18 refluxes one carrier at a time. The loading mechanism 11 and the unloading mechanism 18 are both completed by the lifting mechanism to complete the lifting action.

[0052] Specifically, the soft-pack battery cell processing line also includes a long side positioning mechanism 12, a battery cell scanning mechanism 13, an IV / OCV testing mechanism 14, an NG exclusion mechanism 15, and a flipping and matching mechanism 17. The long side positioning mechanism 12 and the battery cell scanning mechanism 13 are all arranged at the feeding mechanism 11, and the IV / OCV testing mechanism 14, the NG exclusion mechanism 15, the cutting and bending mechanism 16, the dog ear folding mechanism 5, the flipping and matching mechanism 17, and the foam mounting mechanism are arranged in sequence along the conveying direction of the conveying mechanism 1 (from front to back);

[0053] After the battery cell 6 is loaded at the loading mechanism 11, the long side positioning mechanism 12 first completes the centering, and the battery cell scanning mechanism 13 simultaneously performs the battery cell scanning, and then the IV / OCV testing mechanism 13 tests the resistance and voltage of the battery cell 6. After the test is completed, the handling robot in the NG exclusion mechanism 15 takes away the battery cell that is NG in the scanning or NG in the IV / OCV test, and puts it on the NG pull belt for buffering, retains the qualified battery cell 6, and continues to be sent by the battery cell carrier 2 to the cutting and bending mechanism 16 for fixed-length cutting and bending of the battery cell pole ear. After bending, the dog ear folding mechanism 5 folds the dog ear inward. After folding the dog ear, the flipping and matching mechanism 17 selectively flips and matches the battery cell 6 according to the stacking order. After flipping and matching, the foam mounting mechanism performs foam mounting. After foam mounting, the battery cell 6 is sent to the module stacking line for stacking, bracket pre-installation, steel belt covering and other operations. The empty battery cell carrier 2 is sent to the carrier reflow layer through the unloading mechanism 18.

[0054] Further, such as Figures 3 to 5As shown, the battery carrier 2 includes a carrier plate 22, two clamping assemblies 23 symmetrically arranged on both sides of the carrier plate 22, the clamping assembly 23 includes a mounting frame 231, a pressure block 232, an elastic member 233, a cross plate, and two clamping blocks 234.

The elastic member 233 is sleeved on the outside of the guide rod. The pressure block 232 is an L-shaped structure, and its bottom is fixedly connected to the middle part of the cross plate, and the two ends of the cross plate are respectively connected to the bottom of the two clamping blocks 234, and the top of the clamping block 234 is in contact with the long side of the battery cell 6;

[0055] The soft-pack battery cell processing line also includes a clamping mechanism 21, which is used to drive the two clamping assemblies 23 to move in opposite directions to release the battery cell 6;

[0056] Under normal conditions, the two clamping assemblies 23 automatically press the battery cell 6 under the spring force of the elastic member 233, so that the battery cell 6 can maintain its position during high-speed movement, and the accuracy of subsequent processing can be guaranteed without secondary positioning; when the battery cell carrier 2 needs to be opened to remove or clamp the battery cell 6, the clamping blocks 234 in the two clamping assemblies 23 are driven to move in reverse through the clamping mechanism 21, and the elastic member 233 is compressed, and the battery cell carrier 2 is opened. For example, a clamping mechanism 21 is provided at each of the loading mechanism 11, the unloading mechanism 18, the NG removal mechanism 15, and the flipping and matching mechanism 17, so as to open the battery cell carrier 2.

[0057] like Figure 4 , Figure 5 As shown, a pulley 235 is connected to the bottom of the clamping block 234, and the clamping mechanism 21 includes a driving mechanism and two wedge-shaped top blocks 211. One end of the wedge-shaped top block 211 is provided with a chamfer 212, and the inclined surface of the chamfer 212 cooperates with the inner side of the pulley 235. The driving mechanism is used to push the two wedge-shaped top blocks 211. The driving mechanism is preferably a telescopic cylinder. During the pushing process of the telescopic cylinder, the pulley 235 moves along the inclined surface of the chamfer 212 close to the end face of the wedge-shaped top block 211 toward the side face of the wedge-shaped top block 211. The pulley 235 is squeezed by the wedge-shaped top block 211, so that the clamping blocks 234 in the two clamping assemblies 23 move backwards, and finally the battery cell 6 is released.

[0058] like Figure 3 , Figure 4 As shown, a clamping block 234 in one clamping assembly 23 is connected to a cross bar 236 at the top, and the cross bar 236 contacts one long side of the battery cell 6; a floating rod 237 is passed through the top of the clamping block 234 in another clamping assembly 23, and the floating rod 237 contacts the other long side of the battery cell 6; a limit block is provided at the bottom of the carrier plate 22 to prevent the battery cell 6 from being crushed due to excessive compression.

Specifically, the battery core glue spraying mechanism 3 includes a movable glue valve, through which the battery core is sprayed with glue.

[0062] Furthermore, the discharge port is opened at the bottom of the foam silo 41, the X-axis linear module 421 is located below the foam silo 41, and multiple foam silos 41 are arranged along the length direction of the X-axis linear module 421; after each foam is taken out from the foam silo 41, the remaining foam falls naturally and waits for material collection, and there is no need to set a foam position adjustment mechanism; the number of foam silos 41 is at least four, and each foam silo 41 buffers at least 250 pieces of foam, so that the material can be continuously fed for at least 50 minutes; a material collection baffle is provided at the discharge port, and the material collection baffle is opened when the material is collected, and the material collection baffle rebounds after the material collection is completed, blocking the foam inside the foam silo 41 to prevent the foam from falling out.
