Description

Technical Field

[0001] The present invention relates to the field of battery pole piece cutting dies, and in particular to a battery pole piece cutting die. Background Art

[0002] In the field of battery manufacturing, cutting of battery pole pieces is a key step that has a direct impact on the performance and safety of the battery. As the core tool of this step, the precision and stability of the cutting mold are key factors in ensuring the size consistency and quality of the battery pole pieces. However, during the cutting process, the cutting knife of the mold is easily contaminated with pole piece material residues or other contaminants. If these contaminants are not removed in time, it will seriously affect the cutting accuracy and may accelerate the wear of the mold, thereby reducing production efficiency and product quality.

[0003] In order to keep the cutter clean, existing battery electrode cutting molds are usually equipped with special cutter cleaning devices. These cleaning devices clean the cutter during or after cutting to ensure the sharpness of the cutter and the accuracy of cutting. However, in actual applications, due to the limitations of equipment layout, especially the lack of space in front of the mold, the installation and use of the cleaning device has brought challenges.

[0004] Specifically, when the space in front of the die is limited, the cleaning device may not be installed directly on the front side of the die, resulting in the cleaning device being unable to effectively contact the cutter for cleaning. In this case, either a portion of the cleaning effect needs to be sacrificed, or the equipment needs to be substantially modified to accommodate the installation requirements of the cleaning device. However, both solutions are not ideal because sacrificing the cleaning effect will affect the cutting quality, while modifying the equipment will increase cost and complexity.

[0027] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0028] A battery electrode cutting die, such as Figure 1 As shown, it includes a mold frame 1, an upper cutting mold 2, a lower cutting mold 3 and a cutter cleaning device 4.

[0029] The mold frame 1 serves as the supporting structure of the entire mold, and an upper cutting mold 2 and a lower cutting mold 3 are arranged relatively up and down inside the mold frame. Figure 2 As shown, the upper cutting die 2 and the lower cutting die 3 are respectively equipped with an upper cutting knife 21 and a lower cutting knife 31 for cutting the battery pole pieces.

[0030] like Figure 2 and Figure 3 As shown, the cutter cleaning device 4 is arranged on one side of the upper cutting die 2, and is used to clean the upper cutter 21 and / or the lower cutter 31. The cutter cleaning device 4 comprises a cleaning portion 41, a cleaning portion transverse driving device 42 and a transverse guide rail 43.

[0031] like Figure 4 As shown, the cleaning unit 41 is the core component of the cutter cleaning device 4, on which cleaning elements such as a cleaning brush or a cleaning cloth or a cleaning sponge are installed for actually contacting and cleaning the cutter. The cleaning unit 41 is installed on a transverse guide rail 43 and can move along the transverse guide rail 43.

[0032] like Figure 4 As shown, the cleaning unit transverse driving device 42 is the power source for driving the cleaning unit 41 to move, and it can be a cylinder, a motor or other suitable driving device. The cleaning unit transverse driving device 42 is connected to the cleaning unit 41 through a driving rope 421, and can drive the cleaning unit 41 to move transversely along the transverse guide rail 43.

[0033] like Figure 4 As shown, the lateral guide rail 43 includes a horizontal guide rail 431 and a position-avoiding curved guide rail 432. The horizontal guide rail 431 is arranged at the front side of the upper cutting die 2, and its extension direction is parallel to the length direction of the upper cutting die 2, and is used for the movement of the cleaning part 41 during normal cleaning operation. The position-avoiding curved guide rail 432 is arranged on one side of the horizontal guide rail 431, and the position-avoiding curved guide rail 432 is arranged on one side of the upper cutting die 2 along the length direction, and its shape is curved, and is used for the cleaning part 41 to avoid position after cleaning is completed.

[0034] During operation, the cleaning part transverse driving device 42 drives the cleaning part 41 to move along the horizontal guide rail 431, so that the cleaning part 41 contacts and cleans the upper cutter 21 and / or the lower cutter 31. After cleaning, the cleaning part transverse driving device 42 continues to drive the cleaning part 41 to move, so that the cleaning part 41 enters the avoidance curved guide rail 432 and avoids the normal operation of the mold.

[0035] In this embodiment, the cleaning section transverse driving device 42 is driven by a motor. Specifically, the motor is connected to the cleaning section 41 through a transmission rope and a guide roller. When the motor is working, the transmission rope and the guide roller convert the rotational motion of the motor into the linear motion of the cleaning section 41, thereby driving the cleaning section 41 to move along the transverse guide rail 43.

[0036] In addition, in order to more accurately control the moving position and speed of the cleaning unit 41, the present embodiment may also install detection elements such as encoders or position sensors on the motor to monitor the moving state of the cleaning unit 41 in real time and adjust the speed and direction of the motor as needed.

[0037] In summary, the battery electrode cutting mold of the present application realizes automatic cleaning of the upper and lower cutters by setting a cutter cleaning device, thereby improving the cleaning efficiency and production efficiency of the mold. At the same time, the transverse guide rail includes a horizontal guide rail and a curved guide rail for avoiding position, so that the cleaning part can be easily avoided after cleaning is completed, avoiding interference with the normal operation of the mold.

[0038] This embodiment is based on the previous embodiment and specifies the structure of the cleaning unit.

[0039] like Figure 4 As shown, the cleaning unit 41 includes a slider 411, a moving frame 412 and a cleaning block 413. The slider 411 is slidably mounted on the transverse guide rail 43 to ensure that the cleaning unit 41 can move smoothly along the transverse guide rail 43. The cleaning block 413 is mounted on the slider 411 through the moving frame 412, so that the position of the cleaning block 413 can be adjusted according to actual needs.

[0040] like Figure 5 and Figure 6 As shown, the cleaning block 413 may have different structures according to different cleaning objects.

[0041] When the cleaning block 413 cleans only the upper cutter 21 , the cleaning block 413 includes an upper cleaning portion 413 a , and the upper cleaning portion 413 a cleans the upper cutter 21 .

[0042] When the cleaning block 413 cleans only the lower cutter 31 , the cleaning block 413 includes a lower cleaning portion 413 b , and the lower cleaning portion 413 b cleans the lower cutter 31 .

[0043] When the cleaning block 413 needs to clean the upper cutter 21 and the lower cutter 31 at the same time, the cleaning block 413 includes an upper cleaning portion 413a and a lower cleaning portion 413b. The upper cleaning portion 413a cleans the upper cutter 21, and the lower cleaning portion 413b cleans the lower cutter 31.

[0044] like Figure 5 As shown, specifically, the upper cleaning portion 413a may include a V-shaped cleaning groove 413a1, which is used to wipe the front side and the rear side of the upper cutter 21 to ensure the cleanliness of the upper cutter 21. In addition, the upper cleaning portion 413a may also include an upper cleaning protrusion, which is used to specifically wipe the rear side of the upper cutter 21 to perform deep cleaning on a specific part.

[0045] Likewise, the lower cleaning portion 413 b may include a lower cleaning protrusion, which is used to clean the front side of the lower cutter 31 to ensure a cleaning effect of the lower cutter 31 .

[0046] This embodiment improves the installation method of the mold frame 1, the upper cutting mold 2 and the lower cutting mold 3, thereby improving the disassembly and installation efficiency of the mold.

[0047] like Figure 7 As shown, the mold further includes a support plate assembly 5, which is mounted on the mold frame 1 to provide support for the upper cutting mold 2. The upper cutting mold 2 is mounted on the support plate assembly 5 via a first quick-release assembly 6.

[0048] like Figure 7 As shown, the first quick-release assembly 6 includes a first quick-release block 61 and a first quick-release column 62. The first quick-release block 61 is mounted on the upper surface of the upper cutting die 2, and a T-slot 611 is provided on the first quick-release block 61. The first quick-release column 62 is mounted on the bottom of the support plate of the support plate assembly 5, and a columnar joint 621 is provided on the first quick-release column 62 corresponding to the T-slot 611. The columnar joint 621 can be inserted into the T-slot 611 to achieve the upper cutting die 2 being quickly and firmly mounted on the support plate.

[0049] like Figure 7 As shown, the lower cutting die 3 is installed on the lower base plate 11 of the die frame 1 through the second quick-release assembly 7. The second quick-release assembly 7 includes a second quick-release roller 71, and inclined quick-release portions 111 are respectively provided on both sides of the lower base plate 11. The second quick-release roller 71 is pressed against the inclined surface of the inclined quick-release portion 111, and finally locked by bolts to ensure the stable installation of the lower cutting die 3.

[0050] By adopting the first quick-release assembly 6 and the second quick-release assembly 7, the battery pole piece cutting mold of this embodiment realizes the rapid disassembly and installation of the upper cutting mold 2 and the lower cutting mold 3, thereby improving the maintenance efficiency and production efficiency of the mold.
