Description

TECHNICAL FIELD

[0001] The utility model relates to membrane electrode production equipment technical field, especially the membrane electrode frame processing device of a kind of, simultaneously, the utility model also relates to the membrane electrode production system of application this membrane electrode frame processing device. BACKGROUND

[0002] Currently, in the membrane electrode frame processing process, the membrane electrode frame needs to be roll-cut according to requirements, and the waste needs to be discharged into the waste collection part after roll-cut, and the equipment stability is not affected during the waste discharge process.

[0003] However, after roll-cutting, because there is a certain static electricity between the waste and the supporting film, the waste will be delayed to fall, affecting the subsequent visual inspection and tape running stability.

[0004] The existing waste discharge method generally discharges waste in the following ways.

[0005] 1. Use waste removal tape to remove waste by adhesion. This waste removal method increases additional materials, resulting in increased costs; at the same time, the use of waste removal tape introduces a new tension factor, which affects the stability of the equipment. Because the waste may fall directly due to gravity after cutting, the waste removal tape cannot adhere to the waste during cutting.

[0006] 2. Increase the waste removal suction cup mechanism and place it in the waste box by suction cup handling. Because the state of the waste after cutting is unstable, there is a situation where the waste falls due to gravity in advance, so there is a situation where the suction cup cannot adsorb the waste.

[0023] In addition, the waste discharge part is a waste discharge rod extending in the vertical direction, which is beneficial to the natural falling of the waste from the membrane electrode frame material belt under the action of gravity, and has a small contact area with the membrane electrode frame material belt and causes less damage to the membrane electrode frame material belt. The lower end of the waste discharge rod is provided in a semispherical shape, which can further reduce the damage of the waste discharge part to the membrane electrode frame material belt. The lower part of the waste discharge part is provided with a rotating wheel, which also has the effect of reducing the damage to the membrane electrode frame material belt.

[0038] The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0039] Embodiment One

[0040] The present embodiment relates to a membrane electrode frame processing device, which can make the waste material fall smoothly from the membrane electrode frame material belt 4 after roll cutting, and can improve the smoothness and processing efficiency of the membrane electrode frame processing.

[0041] Based on the above design idea, an exemplary structure of the membrane electrode frame processing device of the present embodiment is shown in Figure 1 and Figure 2 As a whole, the membrane electrode frame processing device of the present embodiment mainly includes a pair of rotating rollers 1 and a waste discharge part 2, wherein the pair of rotating rollers 1 is used to roll cut the continuously conveyed membrane electrode frame material belt 4, and the waste discharge part 2 is arranged downstream of the pair of rotating rollers 1 along the conveying path of the membrane electrode frame material belt 4. As shown in Figure 2 The left side of the rotating roller 1 is the downstream of the rotating roller 1.

[0042] In a specific arrangement, the waste discharge section 2 is specifically located above the membrane electrode frame strip 4, and the waste discharge section 2 is used to apply downward pressure to the membrane electrode frame strip 4 after roll cutting.

[0043] To better understand the membrane electrode frame processing apparatus of this embodiment, the structure of the membrane electrode frame strip 4 will be briefly described first. During production, the raw material for preparing the membrane electrode frame is generally rolled from the membrane electrode frame strip 4.

[0044] like Figure 3 The structure shown is a partial cross-sectional view of the membrane electrode frame strip 4. Specifically, the membrane electrode frame strip 4 generally includes four layers: a base film 402, a mask 403, a frame film 404, and a frame release film 405. The base film 402, mask 403, frame film 404, and frame release film 405 are stacked sequentially. The mask 403 is square and consists of multiple units spaced apart along the length of the membrane electrode frame strip 4, as can be seen in existing structures.

[0045] During the processing of the membrane electrode frame strip 4, such as Figure 1 In the shown configuration, the base film 402 is located on the upper side, and the frame release film 405 is located on the lower side. In this embodiment, after the membrane electrode frame processing apparatus roll-cuts the membrane electrode frame strip 4, the cut portions are the frame film 404 and the frame release film 405. The removed portions from the frame film 404 and the frame release film 405 form waste material 401, which is specifically square in shape. Waste material 401 needs to fall off the base film 402 and the mask 403.

[0046] As a preferred embodiment, reference is still made to... Figure 1 and Figure 2 As shown, the aforementioned pair of rollers 1 includes an upper pressure roller 101 and a lower pressure roller 102, which are arranged vertically, and a gap is provided between the upper pressure roller 101 and the lower pressure roller 102 for the membrane electrode frame material strip 4 to pass through. The roller cutters on the upper pressure roller 101 and the lower pressure roller 102 are specifically designed according to the structure in the prior art, so as to roll cut the membrane electrode frame material strip 4 passing through the gap between them.

[0047] It should be noted that in this embodiment, the upper pressure roller 101 and the lower pressure roller 102 are arranged vertically relative to each other, which facilitates the overall arrangement. The size of the gap between the upper pressure roller 101 and the lower pressure roller 102 needs to be determined according to the thickness of the membrane electrode frame strip 4 and the processing requirements to ensure that the strip can pass through smoothly without being over-compressed or damaged.

[0048] For ease of installation, in a preferred embodiment, the waste discharge section 2 is provided on the roller mounting section 5 for mounting a pair of rollers 1. As in this embodiment, refer to...Figure 2 As shown, the roller mounting portion 5 specifically adopts an existing tool holder, and the aforementioned upper pressing roller 101 and lower pressing roller 102 are rotatably mounted on the tool holder, and the specific mounting manner can still refer to the existing structure.

[0049] It should be noted that the waste discharge portion 2 is arranged on the roller mounting portion 5, which is convenient for overall arrangement. The roller 1 is responsible for conveying and processing the material belt, and the waste discharge portion 2 is responsible for applying downward pressure to the membrane electrode frame material belt 4, which facilitates the waste 401 generated after the roll cutting to fall off. Through the cooperative work of the roller 1 and the waste discharge portion 2, the entire processing process of the membrane electrode frame material belt 4 can be ensured to be smoothly carried out, and the production efficiency and product quality can be improved.

[0050] In order to facilitate the installation of the waste discharge portion 2, in the embodiment, the waste discharge portion 2 is specifically mounted on the roller mounting portion 5 through a first mounting bracket 6. The first mounting bracket 6 is fixedly mounted on the roller mounting portion 5 through a first connecting piece 8 such as a connecting shaft, and the waste discharge portion 2 is fixed on the first mounting bracket 6.

[0051] Specifically, the first mounting bracket 6 can be processed with a mounting hole through which the waste discharge portion 2 passes, and the first mounting bracket 6 is provided with a threaded hole in communication with the mounting hole. The axial direction of the mounting hole and the axial direction of the threaded hole are arranged orthogonally, and a bolt is screwed in the threaded hole. When the waste discharge portion 2 is arranged in the mounting hole, the bolt in the threaded hole is tightened, and one end of the bolt screwed into the threaded hole abuts against the waste discharge portion 2, so that the waste discharge portion 2 can be fixed on the first mounting bracket 6.

[0052] As a preferred embodiment, the waste discharge portion 2 includes a waste discharge rod extending in the vertical direction. As shown, Figure 1 As shown, along the axial direction of the roller 1, the waste discharge rod is specifically located at the middle position of the waste 401 region, so as to facilitate the waste 401 to fall off from the membrane electrode frame material belt 4.

[0053] It should be noted that the waste discharge rod can be one, but also can be multiple, such as two, three, etc. Along the axial direction of the roller 1, multiple waste discharge rods are arranged at intervals, which can be uniformly or non-uniformly arranged, so as to facilitate the waste 401 to smoothly fall off from the membrane electrode frame material belt 4.

[0054] In the above structure, the waste discharge portion 2 is arranged as a waste discharge rod extending in the vertical direction, which facilitates the waste 401 to naturally fall off from the membrane electrode frame material belt 4 under the action of gravity, and the contact area with the membrane electrode frame material belt 4 is small, and the damage to the membrane electrode frame material belt 4 is small.

[0055] In order to prevent the waste discharge portion 2 from damaging the membrane electrode frame material belt 4, as a preferred embodiment, still referring to Figure 1As shown, the cross-sectional shape of the upper section of the waste discharge rod is circular, and the lower end of the waste discharge rod is hemispherical, so that the film electrode frame strip 4 is pressed by the spherical area, which can further reduce the damage of the waste discharge part 2 to the film electrode frame strip 4.

[0056] In a preferred embodiment, the part of the waste discharge rod close to the spherical area of the lower end is inverted conical, which facilitates the processing of the spherical area and reduces the damage to the film electrode frame strip 4. In addition, in addition to directly setting the lower end of the waste discharge rod as a hemisphere, for example, a ball can be hinged at the lower end of the waste discharge rod, and the waste discharge rod presses the film electrode frame strip 4 through the ball, which can also better reduce the damage to the film electrode frame strip 4.

[0057] It should be understood that the shape of the waste discharge rod can also be other shapes, for example, the waste discharge part 2 is a waste discharge plate, and the waste discharge plate extends along the axial direction of the rotating roller 1, so that the projection of the lower end of the waste discharge plate on the cross section perpendicular to the axial direction of the rotating roller 1 is arc-shaped, for example Figure 2 The shape shown in the figure also reduces the damage to the film electrode frame strip 4, but in this case, it is necessary to prevent the waste discharge plate from being too large in the axial direction of the rotating roller 1 and damaging the film electrode frame strip 4.

[0058] As another preferred embodiment, in order to facilitate smooth waste discharge and reduce damage to the film electrode frame strip 4, the lower part of the waste discharge part 2 can be provided with a rotating wheel not shown in the figure, which is rotatably installed on the waste discharge part 2, and the axial direction of the rotating wheel is parallel to the axial direction of the rotating roller 1. The waste discharge part 2 presses the film electrode frame strip 4 through the rotating wheel, which also has the effect of reducing the damage to the film electrode frame strip 4.

[0059] During the falling of the waste material 401, there is a certain probability of being rolled into the pressing roller 102, affecting the subsequent cutting. Therefore, as a preferred embodiment, still referring to Figure 1 and Figure 2 As shown, the film electrode frame processing device of the present embodiment also includes a guide part 3 along the conveying path of the film electrode frame strip 4, the guide part 3 is arranged downstream of the pair of rotating rollers 1, and the guide part 3 is arranged below the waste material 401, and the guide part 3 is used to guide the waste material 401 to slide into the waste material collecting part.

[0060] As shown in the state Figure 2 The waste material collecting part can be arranged below and left of the guide part 3 to facilitate the accommodation of the waste material 401 falling from the guide part 3. The waste material collecting part can refer to the existing structure, which has an upper opening accommodating cavity, and the waste material 401 can fall into the accommodating cavity through the opening.

[0061] Specifically, as Figure 2As shown, the guide part 3 is mounted on the rotating roller mounting part 5, i.e. the aforementioned tool seat, through the second mounting bracket 7. More specifically, the second mounting bracket 7 is fixed to the rotating roller mounting part 5 through a second connecting member 9, such as a connecting shaft, and the guide part 3 is mounted on the second mounting bracket 7, for example, through bolts, and the machining and assembly are relatively convenient.

[0062] The guide part 3 provided herein can guide the waste 401 to slide into the waste collecting part, facilitating the smooth waste discharge and the collection of the waste 401. Referring back to Figure 1 and Figure 2 As a preferred embodiment, the guide part 3 includes a guide plate arranged parallel to the axial direction of the rotating roller 1, which can better receive the waste 401 and thus smoothly guide the waste 401 to slide into the waste collecting part.

[0063] As a preferred embodiment, the guide plate gradually inclines downward from a position close to the gap to a position away from the gap, where the gap refers to the gap between the upper pressing roller 101 and the lower pressing roller 102. The guide plate extending from the position close to the gap to the position away from the gap and gradually inclining downward can set the waste collecting part below the membrane electrode border strip 4, facilitating the collection of the waste 401 and the arrangement of the waste collecting part.

[0064] As a preferred embodiment, referring back to Figure 2 As shown, the included angle between the guide plate and the horizontal plane is between 30° and 60°, such as 30°, 40°, 45°, 50°, 60°, etc., which also has the effect of smoothly guiding the waste 401 into the waste collecting part.

[0065] The membrane electrode border processing device of the present embodiment can smoothly drop the waste 401 from the membrane electrode border strip 4 by applying a downward pressure to the waste 401, causing slight deformation of the membrane electrode border strip 4 when passing through the waste discharge part 2, and generating internal stress inside the membrane electrode border strip 4. Due to the presence of the waste area mask 403, there is only slight electrostatic adsorption force between the waste 401 and the bottom supporting film 402, and under the combined action of the aforementioned internal stress and gravity, the waste 401 can overcome the electrostatic force between the waste 401 and the bottom supporting film 402 and smoothly drop from the membrane electrode border strip 4.

[0066] In addition, the waste discharge part 2 and the guide part 3 of the present embodiment have simple structure, are convenient to realize, have low manufacturing cost, and are suitable for waste discharge in a narrow space.

[0067] Embodiment Two

[0068] The present embodiment relates to a membrane electrode production system for preparing a membrane electrode, which includes the membrane electrode border processing device of embodiment one.

[0069] The membrane electrode production system of the embodiment has the same beneficial effects as the membrane electrode frame processing device of the embodiment one relative to the prior art, and will not be described here.

[0070] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
