Description

Technical Field

[0001] This utility model relates to the field of flow battery processing technology, and in particular to a flow battery ion exchange membrane positioning and cutting device. Background Technology

[0002] Ion exchange membranes are one of the most critical components of flow battery stacks, and their processing is a key step in the manufacturing process. Currently, ion exchange membranes are shipped pre-processed rolls, requiring further cutting before application. During this cutting process, in addition to ensuring the integrity of the ion exchange membrane and dimensional accuracy, it is also crucial to maximize the utilization rate of the rolls to reduce processing costs.

[0003] Currently, the main methods for cutting ion exchange membranes include laser cutting, ultrasonic vibrating knife cutting, and machine cutting. Laser cutting generates heat that can affect the properties of the ion exchange membrane. While ultrasonic vibrating knives offer good cutting results, the equipment is expensive, and its parameters must match the size of the roll material; changing the roll material type may render the equipment incompatible. Machine cutting requires precise pressure settings, and prolonged cutting can damage the cutting tools, leading to decreased cutting accuracy. Furthermore, the utilization rate of the roll material using these methods needs improvement. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning and cutting device for ion exchange membranes in flow batteries, which has the advantages of improving roll material utilization and low cost.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] According to an embodiment of this disclosure, a positioning and cutting device for a flow battery ion exchange membrane is provided, comprising:

[0007] A mounting base for mounting with a cutting equipment base;

[0008] A cutting platform is elastically connected to the fixed base and used to support the film material to be cut, and a buffer gap is formed between the cutting platform and the fixed base;

[0009] Positioning strips are disposed on the adjacent two side edges of the cutting platform. These positioning strips are used to position the adjacent two side edges of the film material to be cut, and inlet and outlet ends are formed on the other two sides of the cutting platform, respectively; and...

[0010] A cutting die connected to the drive unit of a cutting device for punching the film material to be cut, wherein the side of the cutting die is in contact with the positioning strip.

[0011] To achieve the above technical solution, during use, the fixed base is fixed to the machine platform of the cutting equipment, and the cutting die is fixed to the drive unit of the cutting equipment. Then, the membrane material to be cut is fed from the feeding end and placed on the cutting platform, with the adjacent sides of the membrane material to be cut aligned with the positioning strip. Next, the drive unit of the cutting equipment drives the cutting die to descend, cutting along the positioning strip to cut out ion exchange membranes that meet the size requirements, and then unloading from the discharge end. Because the membrane material to be cut is precisely positioned during cutting, the cutting accuracy is high, and the membrane material can be maximized during cutting, improving the utilization rate of the roll material and effectively reducing processing costs. Furthermore, because the cutting platform and the fixed base are elastically connected, the punching force can be effectively buffered during punching, reducing the chance of die damage. At the same time, the requirements for processing equipment are lower, and it can be adapted to different equipment installation combinations. When cutting roll materials of different specifications, only the corresponding cutting die needs to be replaced, without the need for frequent equipment replacement, making it more applicable.

[0012] In some exemplary embodiments, a plurality of elastic elements arranged in an array are provided between the cutting platform and the fixed base to form an elastic connection.

[0013] The above technical solution achieves a stable and elastic connection between the cutting platform and the fixed base.

[0014] In some exemplary embodiments, the positioning strip includes: a first positioning strip disposed along the width direction of the cutting platform, and a second positioning strip disposed along the length direction of the cutting platform.

[0015] To achieve the above technical solution, positioning in two directions is achieved through the first positioning bar and the second positioning bar.

[0016] In some exemplary embodiments, the outer periphery of the cutting die is provided with a limiting flange, which is used to abut against the outer surface of the positioning strip to limit the descent position of the cutting die, and when the limiting flange contacts the positioning strip, the bottom end of the cutting die contacts the cutting platform.

[0017] The above technical solution achieves the goal of limiting the descent position of the cutting die by using a limiting flange, thereby preventing the cutting die from being damaged by a large rigid impact with the cutting platform.

[0018] In some exemplary embodiments, the first positioning strip is provided with a plurality of first mounting holes, the second positioning strip is provided with a plurality of second mounting holes, the cutting platform is provided with a plurality of first locking holes adapted to the first mounting holes and second locking holes adapted to the second mounting holes, and locking members for connecting with the first locking holes and the second locking holes are respectively provided in the first mounting holes and the second mounting holes.

[0019] The above technical solution facilitates the installation of the first positioning strip and the second positioning strip.

[0020] In some exemplary embodiments, the fixed base is provided with a first positioning hole at each of its four corners, and the cutting platform is provided with a second positioning hole at each of its four corners corresponding to the first positioning hole. The second positioning hole is used to connect a guide that passes through the first positioning hole.

[0021] Implementing the above technical solution facilitates the guidance and positioning of the cutting platform.

[0022] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0023] This utility model provides a positioning and cutting device for a flow battery ion exchange membrane, comprising: a fixed base for assembly with a cutting equipment; a cutting platform elastically connected to the fixed base for supporting the membrane material to be cut, wherein a buffer gap is formed between the cutting platform and the fixed base; positioning strips disposed on adjacent side edges of the cutting platform, the positioning strips being used to position adjacent side edges of the membrane material to be cut, and forming an inlet end and an outlet end on the other two sides of the cutting platform respectively; and a cutting die connected to the drive unit of the cutting equipment for punching the membrane material to be cut, wherein the side of the cutting die is in contact with the positioning strips. In use, the fixed base is fixed to the machine platform of the cutting equipment, and the cutting die is fixed to the drive unit of the cutting equipment. Then, the membrane material to be cut is fed from the feeding end and placed on the cutting platform, with the adjacent sides of the membrane material to be cut aligned with the positioning strip. Next, the drive unit of the cutting equipment drives the cutting die to descend and cut along the positioning strip to cut out ion exchange membranes that meet the size requirements, and then unloads the material from the discharge end.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 3 As shown, this utility model provides a positioning and cutting device for a flow battery ion exchange membrane, including: a fixed base 10 for assembly with a cutting equipment; a cutting platform 20 elastically connected to the fixed base 10 for carrying the membrane material to be cut, and a buffer gap is formed between the cutting platform 20 and the fixed base 10; positioning strips disposed on adjacent side edges of the cutting platform 20, the positioning strips being used to position the adjacent side edges of the membrane material to be cut, and infeed end and discharge end being formed on the other two sides of the cutting platform 20 respectively; and a cutting die 40 connected to the drive unit of the cutting equipment for punching the membrane material to be cut, the side of the cutting die 40 being in contact with the positioning strips.

[0031] Specifically, the cutting base can be fixed to the cutting equipment table by welding, bonding, bolting or other means. There are several elastic elements 11 arranged in an array between the cutting platform 20 and the fixed base 10 to form an elastic connection. The elastic elements 11 are springs. Usually, 4-12 sets of elastic elements 11 can be set to achieve a stable elastic connection between the cutting platform 20 and the fixed base 10.

[0032] Meanwhile, a first positioning hole 12 is provided at the four corners of the fixed base 10, and a second positioning hole 23 corresponding to the first positioning hole 12 is provided at the four corners of the cutting platform 20. The second positioning hole 23 is used to connect the guide member passing through the first positioning hole 12. The second positioning hole 23 can be a countersunk hole, for example. The guide member can be a guide post. The head of the guide post is embedded in the second positioning hole 23 and does not protrude from the cutting platform 20. The second positioning hole 23 cooperates with the guide post, thereby facilitating the guiding and positioning of the cutting platform 20. In some embodiments, a guide post adapted to the guide post can also be provided at the second positioning hole 23 to improve the stability of the movement of the cutting platform 20.

[0033] The positioning strip includes a first positioning strip 31 arranged along the width direction of the cutting platform 20 and a second positioning strip 32 arranged along the length direction of the cutting platform 20, forming positioning in two directions through the first positioning strip 31 and the second positioning strip 32. Specifically, the first positioning strip 31 is provided with a plurality of first mounting holes 33, and the second positioning strip 32 is provided with a plurality of second mounting holes 34. The cutting platform 20 is provided with a plurality of first locking holes 21 that are adapted to the first mounting holes 33 and second locking holes 22 that are adapted to the second mounting holes 34. Locking members for connecting with the first locking holes 21 and the second locking holes 22 are respectively inserted into the first mounting holes 33 and the second mounting holes 34. The first mounting holes 33 and the second mounting holes 34 are countersunk holes, and the first locking holes 21 and the second locking holes 22 are threaded holes. The locking members are screws, which are inserted into the first mounting holes 33 and the second mounting holes 34 and threadedly connected to the first locking holes 21 and the second locking holes 22, thereby realizing the installation and fixation of the first positioning strip 31 and the second positioning strip 32.

[0034] The cutting die 40 has a limiting flange 41 on its outer periphery. The limiting flange 41 abuts against the outer surface of the positioning strip to limit the descent position of the cutting die 40. When the limiting flange 41 contacts the positioning strip, the bottom end of the cutting die 40 contacts the cutting platform 20. The limiting flange 41 can limit the descent position of the cutting die 40 and prevent the cutting die 40 from being damaged by a large rigid impact with the cutting platform 20. In some embodiments, the cutting die 40 is specifically a frame structure, and a circular sleeve-shaped cutter corresponding to the cutting hole of the ion exchange membrane is provided on its inner side. The outer side of the cutting die 40 can also be provided with a connector for connecting to the drive unit. The drive unit can be, for example, a cylinder, an electric cylinder, a hydraulic cylinder, or the like.

[0035] In use, the fixed base 10 is fixed on the machine platform of the cutting equipment, and the cutting die 40 is fixed on the drive unit of the cutting equipment. Then, the membrane material to be cut is fed from the feeding end and placed on the cutting platform 20, with the adjacent sides of the membrane material to be cut in contact with the positioning strip. Then, the drive unit of the cutting equipment drives the cutting die 40 to descend and cut along the positioning strip to cut out ion exchange membranes that meet the size requirements, and unloads the material from the discharge end. Because the membrane material to be cut is precisely positioned during cutting, the cutting accuracy is high, and the membrane material can be maximized during cutting, improving the utilization rate of the roll material and effectively reducing the processing cost. Moreover, because the cutting platform 20 is elastically connected to the fixed base 10, the punching force can be effectively buffered during punching, reducing the chance of die damage. At the same time, the requirements for processing equipment are lower, and it can be adapted to different equipment installation combinations. When cutting roll materials of different specifications, only the corresponding cutting die 40 needs to be replaced, without the need for frequent equipment replacement, making it more applicable.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model.
