[0031] The ion-exchange membrane is a core component of a flow battery, a polymer membrane used for selective ion permeation of the electrolyte. During flow battery production, the ion-exchange membrane typically needs to be cut to the appropriate size. In existing technologies, operators usually use a rotary cutter for this purpose. The cutting process involves first measuring the ion-exchange membrane's dimensions on a self-healing cutting pad, then using a ruler for straightness positioning, manually fixing the membrane, and finally using the rotary cutter for cutting. This method requires operators to change tools and perform a series of operations including measurement, positioning, fixing, and cutting, which is cumbersome, slow, and time-consuming, resulting in low efficiency.
[0032] Therefore, this embodiment provides an ion exchange membrane cutting fixture and cutting device, which can improve the cutting efficiency and accuracy of ion exchange membranes. Specifically, the cutting device includes a worktable and the aforementioned ion exchange membrane cutting fixture, both of which are placed at a preset position on the worktable.
[0033] Specifically, such as Figure 1As shown, the ion exchange membrane cutting fixture includes a positioning frame 1, a second slide rail 2, and a roller cutter 3. The positioning frame 1 is a frame extending along a first direction, and its interior is used to place the ion exchange membrane. A scale 111 extending along the first direction is provided on the upper surface of the positioning frame 1. A scale value is also provided on the worktable. The preset position of the ion exchange membrane cutting fixture on the worktable refers to the position where the scale 111 on the positioning frame 1 corresponds one-to-one with the scale value on the worktable. The second slide rail 2 extends along a second direction and is slidably mounted on the positioning frame 1 along the first direction. The roller cutter 3 is rotatably mounted on the second slide rail 2 and also slidably mounted on the second slide rail 2 along the second direction for cutting the ion exchange membrane. The first direction is perpendicular to the second direction. For ease of understanding, in this embodiment, the first direction is defined as the X-axis direction in the attached figure, and the second direction is the Y-axis direction.
[0034] In use, first place the ion membrane cutting fixture in the preset position on the worktable, so that the scale 111 on the positioning frame 1 corresponds one-to-one with the scale value on the worktable. Then place the ion membrane on the upper surface of the worktable and position it in the positioning frame 1, so that one end of the ion membrane is aligned with the zero scale. Then push the second slide rail 2, so that the second slide rail 2 drives the roller 3 to slide along the first direction on the positioning frame 1. Since the upper surface of the positioning frame 1 is provided with a scale 111 extending along the first direction, the position of the roller 3 can be determined by the scale 111, thereby adjusting the cutting length. Then push the roller 3 to slide along the second direction on the second slide rail 2. At the same time, the ion membrane is cut by the rolling of the roller 3. After cutting a section, simply push the ion membrane forward continuously to complete the cutting of multiple sections in sequence. Therefore, this ion membrane cutting fixture has a simple structure, low manufacturing cost, and is easy to operate. It can complete the cutting of ion membranes through rapid positioning and cutting. The original operation method of measurement, positioning, fixing, and cutting can be optimized into a positioning and cutting operation method, which improves the cutting efficiency and accuracy of ion membranes.
[0035] Furthermore, such as Figure 1 As shown, the positioning frame 1 includes two first slide rails 11 and a connecting rod 12 connecting one end of the two first slide rails 11. The two first slide rails 11 are spaced apart along a second direction and both extend along a first direction. A second slide rail 2 is slidably mounted on the two first slide rails 11. At least one second slide rail 2 has a scale 111 on its upper end surface. As can be seen from 1, one end of the two second slide rails 2 is connected by the connecting rod 12 to form an integral structure. The connecting rod 12 can be fixed to the end face of the second slide rail 2 by welding, soldering, or screw connection. The other end of the two second slide rails 2 is open for placing the ion membrane into the positioning frame 1. When the ion membrane abuts against the connecting rod 12, the end of the ion membrane can be precisely aligned with the zero scale. Therefore, the positioning frame 1 has a simple structure and low manufacturing cost.
[0036] Furthermore, such as Figure 1 and Figure 2 As shown, both ends of the bottom of the second slide rail 2 are connected to sliders 4 that correspond one-to-one with the two first slide rails 11. Each slider 4 has a groove 41, and the first slide rail 11 is housed within the groove 41 and slides in cooperation with it. By pushing the second slide rail 2, the slider 4 slides along the first slide rail 11. The sliding cooperation between the slider 4 and the first slide rail 11 ensures smoothness and stability of the sliding.
[0037] Specifically, such as Figure 2 As shown, the slider 4 has a U-shaped structure, including a first limiting part 42, a second limiting part 43, and a connecting part 44. The connecting part 44 is connected to the second slide rail 2. The first limiting part 42 and the second limiting part 43 are respectively perpendicularly connected to the two ends of the connecting part 44 to form a sliding groove 41. The slider 4 rests on the first slide rail 11. The first limiting part 42 and the second limiting part 43 are located on the left and right sides of the first slide rail 11, which are used for left and right limiting to ensure the stability of sliding.
[0038] Furthermore, combined Figure 1 and Figure 2 The first slide rail 11 has a first sliding hole 112 extending in a first direction. The first limiting part 42 has a light hole 421 corresponding to the position of the first sliding hole 112. The second limiting part 43 has a threaded hole 431 facing the light hole 421. The ion membrane cutting fixture also includes a locking screw 5. The shank of the locking screw 5 passes through the light hole 421 and the first sliding hole 112 in sequence and is threadedly connected to the threaded hole 431. The head of the locking screw 5 can abut against the outer surface of the first limiting part 42. After loosening the locking screw 5, the slider 4 can drive the second slide rail 2 and the roller cutter 3 to slide along the first slide rail 11, and at the same time drive the locking screw 5 to slide along the first sliding hole 112. When the second slide rail 2 drives the roller cutter 3 to the position to be cut, tighten the locking screw 5. After the locking screw 5 is tightened, the first limiting part 42 and the second limiting part 43 hold the first slide rail 11 on both sides, thereby locking the position of the slider 4 and ensuring that the slider 4 will not move during cutting.
[0039] like Figure 2 As shown, in this embodiment, one of the first slide rails 11 has a first sliding hole 112, and the slider 4 corresponding to the first slide rail 11 has a smooth hole 421 and a threaded hole 431, and a locking screw 5 passes through the slider 4. In other optional embodiments, both first slide rails 11 may have first sliding holes 112, both sliders 4 may have smooth holes 421 and threaded holes 431, and each slider 4 may have a locking screw 5. The configuration can be flexibly set according to actual needs, and no specific limitation is made here.
[0040] Furthermore, such as Figure 1 and Figure 2 As shown, the second slide rail 2 has a second sliding hole 21 extending in a second direction. The ion membrane cutting fixture also includes a connecting screw 6. The shank of the connecting screw 6 passes through the second sliding hole 21 and can slide along the second sliding hole 21. The roller cutter 3 is rotatably mounted on the shank of the connecting screw 6, and the head of the connecting screw 6 abuts against the second slide rail 2. By sliding the connecting screw 6 along the second sliding hole 21, the roller cutter 3 can move in the second direction. While moving, the roller cutter 3 can roll on the ion membrane, thereby completing the cutting work.
[0041] In this embodiment, as Figure 2 As shown, to achieve the rotation of the hob 3, a bearing 7 is fixedly mounted on the connecting screw 6. The bearing 7 is annular, specifically comprising an inner ring, an outer ring, and rolling elements such as balls disposed between the inner and outer rings. The inner and outer rings rotate relative to each other via the balls. The connecting screw 6 engages with the inner ring of the bearing 7, and the hob 3 is rotatably mounted on the connecting screw 6 and connected to the outer ring of the bearing 7. Alternatively, the hob 3 can be directly mounted on the outer ring of the bearing 7. After the hob 3 contacts the ion membrane, as the hob 3 moves along the second direction, it drives the outer ring of the bearing 7 to rotate relative to the inner ring of the bearing 7. During the rotation of the hob 3, the bearing 7 supports the hob 3, reduces friction during its movement, and ensures its rotational accuracy.
[0042] Furthermore, such as Figure 1 and Figure 2 As shown, the ion exchange membrane cutting fixture also includes a handle 8, which is threaded to the free end of the connecting screw 6. The operator can pull the connecting screw 6 through the handle 8 to slide it in the second sliding hole 21, thereby driving the roller 3 to move in the second direction. The operation is convenient and easy to apply force, achieving the purpose of saving time and effort.
[0043] Specifically, such as Figure 1 and Figure 2As shown, the second sliding hole 21 includes a first horizontal section 211, a second horizontal section 212, and an inclined section 213. Both the first horizontal section 211 and the second horizontal section 212 extend along a second direction. The first horizontal section 211 is higher than the second horizontal section 212 and is located outside the positioning frame 1 in the second direction. The inclined section 213 connects the first horizontal section 211 and the second horizontal section 212. When the hob 3 is not working, the connecting screw 6 is pushed into the first horizontal section 211 via the handle 8. Because the first horizontal section 211 is higher and located outside the positioning frame 1, the hob 3 deviates from the ion membrane and does not contact it. At this time, the position of the ion membrane can be adjusted to prevent the hob 3 from being too low and contacting the ion membrane, thus avoiding unnecessary cutting marks. When the roller cutter 3 is needed for cutting, by pulling the handle 8, the connecting screw 6 moves from the first horizontal section 211 through the inclined section 213 to the second horizontal section 212, so that the roller cutter 3 contacts the ion membrane. The connecting screw 6 slides in the second horizontal section 212, thereby driving the roller cutter 3 to move in the second direction. While moving, the roller cutter 3 can roll on the ion membrane, thereby completing the cutting operation.
[0044] The working process of the ion membrane cutting fixture and cutting device provided in this embodiment is as follows:
[0045] 1) First, place the ion membrane cutting fixture in the preset position on the worktable so that the scale 111 on the positioning frame 1 corresponds one-to-one with the scale value on the worktable. Then, place the ion membrane into the positioning frame 1 and abut against the connecting rod 12 so that the end of the ion membrane is aligned with the zero scale.
[0046] 2) Then, loosen the locking screw 5 and push the second slide rail 2 so that the second slide rail 2 drives the roller 3 to slide along the first direction on the first slide rail 11. According to the scale 111 on the upper surface of the first slide rail 11, determine the position of the roller 3 and thus determine the size of the ion membrane cutting length.
[0047] 3) When the second slide rail 2 drives the roller cutter 3 to the position to be cut, tighten the locking screw 5. After the locking screw 5 is tightened, the first limiting part 42 and the second limiting part 43 hug the two sides of the first slide rail 11 to lock the position of the slider 4 and ensure that the slider 4 will not move during cutting.
[0048] 4) Then, by pulling the handle 8, the connecting screw 6 is moved from the first horizontal section 211 through the inclined section 213 to the second horizontal section 212, so that the roller 3 contacts the ion membrane. The connecting screw 6 slides in the second horizontal section 212, thereby driving the roller 3 to move in the second direction. While moving, the roller 3 can roll on the ion membrane, thereby completing the cutting operation of a section of ion membrane.
[0049] 5) After removing the cut section of ion membrane, push the handle 8 so that the connecting screw 6 moves from the second horizontal section 212 through the inclined section 213 back into the first horizontal section 211. At this time, the roller 3 does not contact the ion membrane. Then push the ion membrane forward and re-engage it with the connecting rod 12 so that the end of the ion membrane is aligned with the zero mark again. Repeat step 4) above to complete the cutting of multiple sections of ion membrane in sequence.
[0050] 6) When it is necessary to readjust the cutting length of the ion exchange membrane and cut it, simply perform steps 2) to 5) above.
[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
