Description

Technical Field

[0001] The utility model relates to the technical field of lithium - ion battery case production, in particular to a die - cutting machine for lithium - ion battery cases. Background Art

[0002] The lithium - ion battery case has high mechanical strength, which can protect the internal structure of the battery from the outside world and also helps to maintain the shape and stability of the battery. There are mainly three types of lithium - ion battery cases: steel cases, aluminum cases and soft cases. A die - cutting machine is a mechanical device mainly used for die - cutting, indentation and gilding operations on materials. The die - cutting machine uses a cutter to cut the material into a certain shape. When producing lithium - ion battery cases, a die - cutting machine is needed to cut the plate - shaped raw material of the lithium - ion battery case into a suitable shape for subsequent assembly.

[0003] The current die - cutting machine is operated manually to cut the plate - shaped raw material. The operation process is as follows: Select a suitable cutter according to the need and install it on the tool die base of the die - cutting machine. Then determine the plate - shaped raw material to be cut and place it on the workbench of the die - cutting machine. After starting the die - cutting machine, the die will press down on the plate - shaped raw material and cut it into the specified shape. After the plate - shaped raw material is cut into the required shape, the die will rise and leave the plate - shaped raw material. At this time, the cut plate - shaped raw material can be taken out from the workbench. The above is the entire cutting process of the plate - shaped raw material. However, there are still deficiencies in practice. For example, every time when cutting plate - shaped raw materials of different specifications, it is necessary to re - select a suitable cutter and install it on the tool die base of the die - cutting machine. The installation of the cutter and the tool die base usually uses connecting parts such as bolts and nuts for installation, resulting in cumbersome installation steps and inconvenient cutter replacement.

[0004] Therefore, there is a particular need for a die - cutting machine for lithium - ion battery cases to solve the problems existing in the prior art. Summary of the Utility Model

[0005] In order to overcome the shortcomings that the installation steps of the cutter and the tool die base of the current die - cutting machine are cumbersome and it is inconvenient to replace the cutter, the utility model provides a die - cutting machine for lithium - ion battery cases.

The top of the mounting plate is fixedly connected to the support plate, and the pull rod is slidably connected to the support plate. The lower end of the pull rod is fixedly connected to the connecting plate, and a plurality of clamping rods are fixedly connected to the bottom of the connecting plate. The clamping rod is clamped with the tool so that the tool is fixed inside the mounting plate, and the pull rod is pulled upward, so that the connecting plate drives the clamping rod to move upward and disengage from the tool.

[0007] Optionally, a second electric push rod and a push plate are also included. The second electric push rod is installed on the front side of the lower part of the support frame, and the push plate is fixedly connected to the telescopic rod of the second electric push rod.

[0010] Optionally, a spring is also included, and the outer sleeve of the pull rod is provided with a spring for assisting reset.

[0011] Optionally, a controller is also included. The controller is installed on the front side of the right part of the support frame, and the controller is electrically connected to the first electric push rod, the second electric push rod and the fan.

[0012] From the above description of the structure of the utility model, it can be known that the design starting point, concept and advantages of the utility model are: 1. By setting a support plate, a pull rod, a connecting plate and a clamping rod, the original tool is taken out of the mounting plate and a suitable tool is placed in. After placing it in, the pull rod is released, and the spring returns to its original state to make the pull rod move downward.

[0013] 2. By setting up a second electric push rod and a push plate, turn on the second electric push rod, control its telescopic rod to retract and extend back and forth, and when retracting, the push plate moves backward to push the waste in the aggregate trough down, thereby eliminating the need for manual picking up of the waste.

[0014] 3. By setting the connecting rod and the cleaning brush, controlling the telescopic rod of the second electric push rod to extend and retract back and forth, the cooperation of the push plate and the connecting rod enables the cleaning brush to move back and forth and back and forth, brushing off foreign matters and other impurities on the surface of the plate-shaped raw material, so as to keep the position to be cut on the surface of the plate-shaped raw material clean, and avoid the influence of foreign matters and other impurities on the surface of the plate-shaped raw material on the cutting quality.

[0015] 4. By setting the blower and the nozzle, turning on the blower, the blower operates to draw in outside air and deliver the outside air into the nozzle for spraying.

[0024] See also Figures 1 - 3 As shown, it also includes a second electric push rod 4, a push plate 401, a connecting rod 301 and a cleaning brush 3. The second electric push rod 4 is connected to the front side of the lower part of the support frame 2 by bolts. The push plate 401 is connected to the telescopic rod of the second electric push rod 4 by welding. The push plate 401 is located in front of the aggregate trough 801 and can extend into the aggregate trough 801. The push plate 401 is connected to the connecting rod 301 by bolts. The left end of the connecting rod 301 is connected to the cleaning brush 3, and the bristles of the cleaning brush 3 are in contact with the top surface of the base 8.

[0025] See also Figure 1 and Figure 2 As shown, it also includes a fan 5 and a nozzle 6. The fan 5 is connected to the rear side of the lower part of the support frame 2 by bolts. The fan 5 is connected to the nozzles 6 distributed on the left and right. The nozzles of the nozzles 6 are downward facing the aggregate trough 801 and the surroundings of the aggregate trough 801.

[0026] See also Figure 1 As shown, a controller 7 is also included. The front right side of the support frame 2 is connected to the controller 7 by bolts. The controller 7 is electrically connected to the first electric push rod 1 , the second electric push rod 4 and the fan 5 .

[0027] Initially, the telescopic rod of the second electric push rod 4 is in the extreme extended state. When cutting the plate-shaped raw material, first, the staff places the plate-shaped raw material to be cut on the left side of the base 8, and then turns on the second electric push rod 4 through the controller 7 to control the telescopic rod of the second electric push rod 4 to extend and retract back and forth. Thus, the push plate 401 drives the connecting rod 301 to move back and forth, and the connecting rod 301 drives the cleaning brush 3 to move back and forth. Subsequently, the staff pushes the plate-shaped raw material from left to right. During the pushing process, the cleaning brush 3 contacts the plate-shaped raw material and brushes off foreign matters and other impurities on its surface, so that the position to be cut on the surface of the plate-shaped raw material is kept clean, avoiding the influence of foreign matters and other impurities on the cutting quality. When the plate-shaped raw material is pushed to a suitable position and the position to be cut is located below the cutter 102, wait for the telescopic rod of the second electric push rod 4 to extend to the initial state and turn it off. Then turn on the first electric push rod 1 and control the telescopic rod of the first electric push rod 1 to extend, so that the mounting plate 101 drives the cutter 102 to move downward to cut the plate-shaped raw material. The waste generated during cutting falls into the aggregate tank 801. After cutting is completed, control the telescopic rod of the first electric push rod 1 to retract, so that the mounting plate 101 drives the cutter 102 to move upward to reset. Finally, take the cut plate-shaped raw material off the base 8. After taking it off, turn on the second electric push rod 4 again and control its telescopic rod to retract and extend back and forth once. When retracting, the push plate 401 moves backward to push the waste in the aggregate tank 801 down, so that the waste falls into the collection box placed at the rear side of the base 8 in advance, thus eliminating the need for manual removal of the waste. Then turn on the blower 5. The blower 5 operates to draw in outside air and deliver the outside air to the nozzle 6 for spraying. When the air is sprayed, the waste debris remaining in the aggregate tank 801 and around the aggregate tank 801 is blown away, thereby realizing the automatic cleaning of the waste debris and reducing the workload of the staff. After cleaning is completed, turn off the blower 5 and repeat the above steps to perform cutting operations on the next plate-shaped raw material. When the cutter 102 needs to be replaced, the staff pulls the pull rod 105 upward by hand, and the spring 104 is compressed accordingly. The connecting plate 103 drives the clamping rod 107 to move upward to disengage from the cutter 102. Then take out the original cutter 102 from the mounting plate 101 and put in a suitable cutter 102. After putting it in, release the pull rod 105, and the spring 104 returns to its original state, causing the pull rod 105 to move downward. The connecting plate 103 drives the clamping rod 107 to move downward to be clamped with the suitable cutter 102, fixing the suitable cutter 102 in the mounting plate 101, thereby realizing the quick disassembly and fixing of the cutter 102, facilitating the replacement of the cutter 102, and meeting the cutting requirements of plate-shaped raw materials of different specifications.
