Description

Technical Field

[0001] This utility model relates to the field of battery separator technology, and in particular to a cutting device for new energy battery separators. Background Technology

[0002] A lithium battery pack is a complex system, mainly composed of battery cells, battery management system, thermal management system, electrical system, structural components, etc. Battery cells are the most basic elements of battery packs and battery modules, including cylindrical lithium batteries, cubic lithium batteries, and pouch lithium batteries. Lithium metal batteries generally use manganese dioxide as the positive electrode material, lithium metal or its alloy metals as the negative electrode material, and use a non-aqueous electrolyte solution.

[0003] When assembling battery packs, it is often necessary to install separators between adjacent battery packs to isolate them. During production, separators are generally large-sized thin plate structures. When in use, they need to be cut using appropriate cutting equipment to form small-sized separators of suitable dimensions. Based on this, a cutting device for new energy battery separators is proposed for rapid cutting of separators. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cutting device for separators of new energy batteries, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a cutting device for a new energy battery separator, including a base plate with one side curved upwards. A cutting plate is embedded in the middle of the top surface of the base plate. Two limiting grooves are formed on one side of the top surface of the base plate, and a movable seat that slides along its length is installed between the two grooves. An arc-shaped operating handle is installed in the middle of the top surface of the movable seat, and a pressing mechanism is installed on one side of the top surface of the movable seat. A fixed seat is installed on the side of the base plate near the cutting plate, and a rotatable pressing handle is installed in the middle of the fixed seat. A cutting blade that cooperates with the cutting plate is installed on its bottom surface.

[0006] Preferably, in any of the above embodiments, support legs are installed at the four corners of the bottom surface of the base plate, and a stepped groove adapted to the base plate is provided near the cutting plate. The support legs in this embodiment facilitate stable support of the base plate, giving the top surface of the base plate a certain height, which makes it easier for operators to place and remove the battery separators. At the same time, the bottom end of the stepped groove allows the debris generated when the battery separators are cut to fall off in time, avoiding blockage of the cutting plate. Meanwhile, the operator can use tools to clean up the debris in a timely manner.

[0007] Preferably, in any of the above embodiments, a scale is installed on the side of the base plate near the fixed seat, and a pointer pointing to the scale is installed at one end of the movable seat. In this embodiment, the pointer moves with the movable seat to measure the required cutting length of the battery separator, which is convenient for the user to operate. The movable seat can be pushed to slide left and right to adjust the cutting length of the battery separator as needed. The adjustment is free. At the same time, the end face of the movable seat is T-shaped, which makes it easy for the operator to move the movable seat left and right. Its structure is simple and easy for the user to operate.

[0008] Preferably, in any of the above embodiments, the end face of the movable seat is T-shaped, and two sliders are installed on the bottom surface of the movable seat. The two sliders are slidably installed inside two limiting grooves. In this embodiment, the two sliders are installed inside the limiting grooves, which facilitates the limiting of the left and right movement of the movable seat and ensures the sliding accuracy of the movable seat. At the same time, the two sliders are connected to the movable seat by bolts. By adjusting the tightening length of the two bolts, the relative friction between the movable seat and the base plate is adjusted, thereby adjusting the magnitude of the pushing force of the movable seat.

[0009] Preferably, as described in any of the above embodiments, a tension spring is installed between the top surface of the pressing handle and the top end of one side of the fixed base, and a protective sleeve is installed at the end of the pressing handle. This embodiment facilitates pulling the pressing handle, allowing it to be released after the battery separator has been cut. The tension spring causes the pressing handle to rotate upwards and reset, making it easy for the user to pick up and put down the battery separator. The protective sleeve at the end of the pressing handle provides a gripping position for the operator, facilitating the rotation of the pressing handle. The protective sleeve can be made of rubber or silicone to improve the operator's grip comfort.

[0010] Preferably, in any of the above embodiments, the clamping mechanism includes a clamping plate, two limiting shafts, two springs, a limiting plate, and two locking nuts. The two limiting shafts are installed on both sides of the top surface of the clamping plate, and the two springs are installed on the outer walls of the two limiting shafts. The top ends of the two limiting shafts are slidably connected to the middle of the top surface of the movable seat. The two ends of the limiting plate are installed on the top ends of the limiting shafts and locked by the two nuts. In this embodiment, the two springs facilitate pushing the clamping plate to form a clamping force, which facilitates clamping the battery separator. At the same time, the two limiting shafts slide relative to the movable seat, which facilitates guiding the movement of the clamping mechanism. Furthermore, the top end of the limiting shaft is stepped, which facilitates limiting the installation of the limiting plate. After being connected with the two locking nuts, it is convenient to clamp the limiting plate.

[0011] Preferably, in any of the above solutions, the arc-shaped position of the arc-shaped operating handle is aligned with the center of the bottom surface of the limiting plate. This solution facilitates the relative rotation between the arc-shaped structure of the operating handle and the limiting plate by pressing the arc-shaped operating handle, thereby raising the limiting plate to a higher position and causing the pressing plate to move synchronously, thus releasing the pressure on the battery separator and making it easier for the operator to pick up and put down the battery separator.

[0012] This utility model has the following advantages:

[0013] 1. This new energy battery separator cutting device has a base plate with a horizontally sliding movable seat installed on one side of its top surface. The movable seat is equipped with a clamping mechanism, which can clamp and fix one side of the battery separator and slide with the movable seat. The pointer measures the moving distance of the movable seat. After the moving distance is reached, the lower handle is pressed to make the cutting blade cooperate with the cutting plate to complete the cutting operation of the battery separator. The overall structure is simple, the design is reasonable, and it is easy to promote and use.

[0014] 2. The cutting device for the new energy battery separator has a base plate with one side tilted upwards, and the moving seat end face is T-shaped, which facilitates the placement and positioning of the battery separator. It has an arc-shaped operating handle and a clamping mechanism. One side of the arc-shaped operating handle is attached to the middle of the bottom surface of the limiting plate, and then one side of the arc-shaped operating handle is pressed down, so that its arc position slides relative to the limiting plate, causing the clamping plate to be lifted up, which makes it easy for the operator to pick up and put down the battery separator.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 6 As shown, a cutting device for a new energy battery separator includes a base plate 1 with one side curved upwards. A cutting plate 2 is embedded in the middle of the top surface of the base plate 1. Two limiting grooves 3 are opened on one side of the top surface of the base plate 1, and a movable seat 4 that slides along its length is installed between the two grooves. An arc-shaped operating handle 6 is installed in the middle of the top surface of the movable seat 4. A pressing mechanism 5 is installed on one side of the top surface of the movable seat 4. A fixed seat 9 is installed on the side of the base plate 1 near the cutting plate 2. A rotatable pressing handle 11 is installed in the middle of the fixed seat 9. A cutting blade 12 that cooperates with the cutting plate 2 is installed on the bottom surface of the fixed seat 9. One side of the cutting blade 12 is fixedly connected to the middle of the pressing handle 11 by bolts, which facilitates the unscrewing of the bolts later for grinding or replacement of the cutting blade 12.

[0024] Support legs are installed at the four corners of the bottom surface of the base plate 1. A stepped groove 13 is provided on the base plate 1 near the cutting plate 2. As an optional technical solution of this utility model, the support legs can provide stable support for the base plate 1, so that the top surface of the base plate 1 has a certain height, which makes it easier for the operator to place and remove the battery separator. At the same time, the bottom end of the stepped groove 13 allows the debris generated when the battery separator is cut to fall down in time, avoiding blockage of the cutting plate 2. Meanwhile, the operator can use tools to clean up the debris in time.

[0025] A scale 8 is installed on the side of the base plate 1 near the fixed seat 9, and a pointer 7 pointing to the scale 8 is installed on one end of the movable seat 4. As an optional technical solution of this utility model, the pointer 7 can move with the movable seat 4 to measure the required cutting length of the battery separator, which is convenient for the user to operate. The movable seat 4 can be pushed to slide left and right to adjust the cutting length of the battery separator as needed. The adjustment is free. At the same time, the end face of the movable seat 4 is T-shaped, which makes it easy for the operator to move the movable seat 4 left and right. Its structure is simple and easy for the user to operate.

[0026] The end face of the movable seat 4 is T-shaped. Two sliders 14 are installed on the bottom surface of the movable seat 4. The two sliders 14 are slidably installed inside the two limiting grooves 3. As an optional technical solution of this utility model, the two sliders 14 are installed inside the limiting grooves 3, which facilitates the limitation of the left and right movement of the movable seat 4 and ensures the sliding accuracy of the movable seat 4. At the same time, the two sliders 14 are connected to the movable seat 4 by bolts. By adjusting the tightening length of the two bolts, the relative friction between the movable seat 4 and the base plate 1 is adjusted, and the magnitude of the pushing force of the movable seat 4 is adjusted.

[0027] A tension spring 10 is installed between the top surface of the pressing handle 11 and the top of one side of the fixed base 9. A protective sleeve is installed at the end of the pressing handle 11. As an optional technical solution of this utility model, this facilitates the pulling of the pressing handle 11. After the battery separator is cut, the pressing handle 11 can be released and the tension spring 10 causes the pressing handle 11 to rotate upward and reset, making it convenient for the user to pick up and put down the battery separator. The protective sleeve at the end of the pressing handle 11 provides a grip position for the operator and facilitates the rotation of the pressing handle 11. The material of the protective sleeve can be rubber or silicone to improve the operator's grip comfort.

[0028] The clamping mechanism includes a clamping plate 501, two limiting shafts 502, two springs 503, a limiting plate 504, and two locking nuts 505. The two limiting shafts 502 are mounted on both sides of the top surface of the clamping plate 501, and the two springs 503 are mounted on the outer walls of the two limiting shafts 502. The top ends of the two limiting shafts 502 are slidably connected to the center of the top surface of the movable seat 4. The two ends of the limiting plate 504 are mounted on the top ends of the limiting shafts 502 and locked by the two nuts 505. In a novel optional technical solution, two springs 503 facilitate pushing the pressing plate 501 to form a pressing force, which facilitates pressing the battery separator. At the same time, the two limiting shafts 502 slide relative to the moving seat 4, which facilitates guiding the movement of the pressing mechanism 5. The top of the limiting shaft 502 is stepped, which facilitates limiting the installation of the limiting plate 504. After being connected with two locking nuts 505, it is convenient to press the limiting plate 504.

[0029] The arc-shaped operating handle 6 is positioned to fit against the center of the bottom surface of the limiting plate 504. As an optional technical solution of this utility model, this facilitates the relative rotation between the arc-shaped structure of the operating handle 6 and the limiting plate 504 by pressing the arc-shaped operating handle 6, thereby raising the limiting plate 504 to a higher position. This, in turn, drives the pressing plate 501 to move synchronously, releasing the pressure on the battery separator and making it easier for the operator to pick up and put down the battery separator.

[0030] The following steps are required when using this new energy battery separator cutting device:

[0031] 1) When using, align one side of the battery separator with the raised position of the base plate 1;

[0032] 2) Press down the arc-shaped operating handle 6 to lift the clamping mechanism 5 a certain distance, and at the same time place one end of the battery separator at the vertical corner of the movable seat 4 to abut against it.

[0033] 3) Release the arc-shaped operating handle 6, and the clamping mechanism 5 will clamp the partition;

[0034] 4) Push the movable seat 4 to move horizontally, and at the same time adjust the cutting size of the battery separator by referring to the relative position of the pointer 7 and the scale 8;

[0035] 5) After adjustment, move the pressing handle 11 downward to make the cutting blade 12 cooperate with the cutting plate 2 to complete the cutting process of the battery separator.

[0036] In summary, during use, the base plate 1 has a horizontally sliding movable seat 4 mounted on one side of its top surface. A clamping mechanism 5 is installed on the movable seat 4, which effectively clamps and fixes one side of the battery separator. The movable seat 4 slides along with the clamping mechanism 4. The pointer 7 measures the movement distance of the movable seat 4. Once the movement distance is reached, pressing down the handle 11 activates the cutting blade 12, which engages with the cutting plate 2 to complete the cutting operation of the battery separator. The overall structure is simple and the design is reasonable. The design facilitates widespread use. A base plate 1 is designed with one side raised, and the movable seat 4 has a T-shaped end face, which helps to limit the placement of the battery separator. An arc-shaped operating handle 6 and a pressing mechanism 5 are provided. One side of the arc-shaped operating handle 6 is aligned with the center of the bottom surface of the limiting plate 504. Pressing down on one side of the arc-shaped operating handle 6 allows it to slide relative to the limiting plate 504, raising the pressing plate 501 and facilitating the operator's placement and removal of the battery separator.
