Description

Technical Field

[0001] This utility model relates to a thin film flipping heating mechanism, belonging to the field of membrane electrode processing technology. Background Technology

[0002] CCM (catalyst-coated membrane) and border film are materials used in membrane electrode products. In membrane electrode fabrication equipment, the encapsulation process for CCM and border film typically involves the following steps: When using a hot-melt border film with initial tack (border films are categorized as hot-melt or pressure-sensitive, requiring heating), the CCM and border film are first adsorbed and positioned in a fixture, then pressed together by the upper and lower pressure plates of the fixture, and finally hot-pressed. This method is complex and affects encapsulation efficiency. Furthermore, because conventional membrane electrode fabrication equipment uses two separate mechanisms to adsorb the CCM and border film before subsequent hot-pressing processes, it also results in a complex overall equipment structure, large space requirements, and high costs.

[0003] In the prior art, utility model patent CN219626693U discloses a tooling for preparing a membrane electrode, which includes a hot-pressing mechanism and two rotatably connected adsorption platforms for adsorbing a CCM and a sealing frame with initial tack, respectively. The two adsorption platforms rotate relative to each other to bring the sealing frame with initial tack into contact with the CCM, and then the hot-pressing mechanism achieves encapsulation. This method is simple to operate, suitable for mass production, and improves the encapsulation efficiency of the membrane electrode. While this patent solves the problem of complex processes affecting encapsulation efficiency in the aforementioned methods, it still has the following drawbacks: because the two adsorption platforms are normally set at a 180° angle, they still occupy a large space, resulting in a large, complex, and costly overall membrane electrode preparation equipment. Utility Model Content

[0004] The present invention aims to provide a thin film flipping heating mechanism to solve the problems of complex structure, large space occupation, and high cost of the original mechanism.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A thin-film flipping heating mechanism includes a bracket, a CCM suction plate, a frame suction plate, and a heating element disposed within the frame suction plate. The bracket has a mounting cavity, and a mounting frame is disposed within the mounting cavity. A drive unit connected to the mounting frame is mounted on the bracket. The CCM suction plate and the frame suction plate are respectively connected to both sides of the mounting frame.

[0007] Therefore, when the film needs to be flipped, the drive unit drives the mounting frame to rotate, thereby driving the mounting frame to rotate 180°, thus realizing the flipping of the CCM and the frame film and heating the frame film, thereby solving the problems of complex structure, large space occupation and high cost of the original mechanism.

[0008] Furthermore, the drive unit includes a drive motor fixed in the mounting cavity, a transmission device connected to the drive motor, and a drive shaft connected to the transmission device. The output shaft of the drive motor is perpendicular to the drive shaft, and the drive shaft is fixed to the mounting bracket.

[0009] Furthermore, the transmission device is a worm gear mechanism.

[0010] Furthermore, the drive shaft is a hollow shaft, the bracket is equipped with a vacuum generator and an electrical slip ring connected to the hollow shaft, the CCM suction plate and the frame suction plate pass through the hollow shaft through pipes and are connected to the vacuum generator or the electrical slip ring, and the heating element passes through the hollow shaft through a line and is connected to the electrical slip ring.

[0011] Furthermore, the vacuum generator is connected to the electrical slip ring via a pipeline, and the CCM suction plate and the frame suction plate are respectively connected to the electrical slip ring via pipelines passing through the hollow shaft.

[0012] Furthermore, the hollow shaft is provided with a through hole, through which the pipe and line pass respectively.

[0013] Furthermore, a heat insulation layer is provided between the CCM suction plate and the mounting bracket and / or between the frame suction plate and the mounting bracket.

[0014] Furthermore, both the CCM suction plate and the frame suction plate are honeycomb panel structures, and the mounting frame is a hollow skeleton with several pores.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The thin film flipping heating mechanism of this utility model integrates the structure of adsorbing CCM and the frame film and the structure of heating the frame film into one mechanism. Compared with the original mechanism, it is smaller in size and has the advantages of small space occupation, simple structure and low cost.

[0017] 2. The thin film flipping heating mechanism of this utility model reduces the space occupied and makes the spatial layout more compact and reasonable by setting the output shaft of the drive motor perpendicular to the drive shaft and connecting them with a transmission device, namely a worm gear mechanism, compared with the setting of directly connecting the output shaft of the drive motor and the drive shaft coaxially.

[0018] 3. The film flipping heating mechanism of this utility model has good heat insulation performance by setting a heat insulation layer between the CCM suction plate and the mounting frame and / or between the frame suction plate and the mounting frame.

[0019] 4. The film flipping heating mechanism of this utility model reduces weight by setting both the CCM suction plate and the frame suction plate as honeycomb plate structures and setting the mounting frame as a hollow skeleton with several pores, making the structure lighter and cheaper.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "up," "down," "left," and "right" appearing below only indicate that they correspond to the up, down, left, and right directions in the accompanying drawings and do not limit the structure.

[0028] like Figures 1 to 5 As shown, the thin-film flipping heating mechanism of this embodiment is widely used in industries such as lithium batteries and hydrogen batteries, and is used in equipment for preparing and processing membrane electrodes. The thin-film flipping heating mechanism of this embodiment includes a bracket 1 for mounting other components, a CCM suction plate 2 for adsorbing CCM, a frame suction plate 3 for adsorbing frame film, a heating element for heating the frame film disposed in the frame suction plate 3, a mounting frame 4 on both sides for mounting the CCM suction plate 2 and the frame suction plate 3 respectively, and a drive unit connected to the mounting frame 4; wherein, the bracket 1 has a mounting cavity 12, and the mounting frame 4 is installed in the mounting cavity 12.

[0029] In practical applications, some embodiments of the drive unit include a drive motor 5 fixed within the mounting cavity 12, a transmission device 6 connected to the drive motor 5, and a drive shaft 7 connected to the transmission device 6 and fixed to the mounting frame 4. The drive motor 5 drives the drive shaft 7 to rotate via the transmission device 6, thereby driving the mounting frame 4 to rotate and achieving the flipping of the CCM and frame film adsorbed by the suction plates on both sides of the mounting frame 4. The output shaft of the drive motor 5 is perpendicular to the drive shaft 7, and the transmission device 6 between them is a worm gear mechanism. Thus, compared to directly connecting the output shaft of the drive motor 5 to the drive shaft 7 coaxially, the film flipping heating mechanism of this embodiment can reduce the space occupied and has a more compact and reasonable spatial layout. The drive shaft 7 is rotatably connected to the bracket 1, which facilitates smoother rotation of the drive shaft 7 and provides support for the drive shaft 7, making the entire structure more stable. In implementation, a bearing 11 is provided on the bracket 1, and the drive shaft 7 is fitted into the bearing 11.

[0030] In practical applications, the drive shaft 7 in some embodiments is a hollow shaft made of seamless steel tubing. The bracket 1 is equipped with a vacuum generator 8 and an electrical slip ring 9 connected to the hollow shaft. The vacuum generator 8 serves to draw air and attract, while the hollow shaft and electrical slip ring 9 prevent wire tangling. To ensure the attraction of the CCM suction plate 2 and the frame suction plate 3, the CCM suction plate 2 and the frame suction plate 3 are respectively connected to the vacuum generator 8 via pipes through the hollow shaft; alternatively, the CCM suction plate 2 and the frame suction plate 3 are respectively connected to the electrical slip ring 9 via pipes, and then the vacuum generator 8 is connected to the electrical slip ring 9 via pipes (this arrangement is simpler and more convenient for wiring). To ensure the heating effect of the heating element, the heating element is connected to the electrical slip ring 9 via a wire passing through the hollow shaft. The heating element is a heating wire arranged inside the frame suction plate 3. A wire hole 71 is provided in the middle of the hollow shaft. The wire hole 71 is used for the pipes connecting the CCM suction plate 2 and the frame suction plate 3 and the lines connecting the heating element to pass through the hollow shaft.

[0031] In practical applications, to ensure that the film flipping heating mechanism of this embodiment has good heat insulation performance, a heat insulation layer 10 is provided between the CCM suction plate 2 and the mounting frame 4 and / or between the frame suction plate 3 and the mounting frame 4. The heat insulation layer 10 can be a heat insulation strip made of any heat insulation material, arranged according to the structural shape of the mounting frame 4.

[0032] In practical applications, both the CCM suction plate 2 and the frame suction plate 3 are honeycomb aluminum plate structures, and the mounting frame 4 is a hollow skeleton with several pores composed of several interlaced aluminum plates; this arrangement can reduce weight, making the structure lighter and cheaper. The bracket 1 is a frame structure, and the drive unit is located inside the frame structure or in other words, inside the mounting cavity 12 (the drive motor 5 and the transmission device 6 are located inside the frame structure, and the drive shaft 7 passes through the center of the frame structure), while the vacuum generator 8 and the electric slip ring 9 are located outside the frame structure.

[0033] The working principle of the thin film flipping heating mechanism in this embodiment is as follows:

[0034] The CCM is adsorbed by the CCM suction plate 2, and the frame film is adsorbed by the frame suction plate 3, which is heated by the heating element inside the frame suction plate 3. When flipping is required, the drive unit operates, that is, the drive motor 5 drives the drive shaft 7 to rotate 180° through the transmission device 6, thereby driving the mounting frame 4 to rotate 180°. After adsorption and flipping are completed, the next process can be carried out (such as rolling or other corresponding operations performed by the rolling device in the equipment for preparing processed film electrodes). In practice, the corresponding operations or steps can be flexibly adjusted according to requirements.

[0035] The advantages of this invention are as follows: By integrating the structure of the adsorption CCM and the frame film, as well as the structure of heating the frame film, into a single mechanism, the film flipping heating mechanism of this embodiment is smaller in size than the original mechanism, and has advantages such as small footprint, simple structure, and low cost. By setting the output shaft of the drive motor 5 perpendicular to the drive shaft 7 and connecting them with the transmission device 6, i.e., the worm gear mechanism, compared to directly connecting the output shaft of the drive motor 5 to the drive shaft 7 coaxially, the film flipping heating mechanism of this embodiment can reduce the space occupied and has a more compact and reasonable spatial layout. By setting a heat insulation layer 10 between the CCM suction plate 2 and the mounting frame 4 and / or between the frame suction plate 3 and the mounting frame 4, the film flipping heating mechanism of this embodiment has good heat insulation performance. By setting both the CCM suction plate 2 and the frame suction plate 3 as honeycomb plate structures, and setting the mounting frame 4 as a hollow skeleton with several pores, the film flipping heating mechanism of this embodiment can reduce weight, making the structure lighter and the cost lower.
