[0030] In related technologies, the coating process involves extruding a coating slurry through a coating die at a specific flow rate and pressure, thereby uniformly transferring it onto the substrate. To achieve high-precision coating, it is necessary to precisely control the flow rate and pressure of the slurry extruded from the coating die. The slurry feeding equipment typically uses devices such as screw pumps. However, screw pumps offer poor controllability in terms of slurry flow rate and pressure, making it difficult to regulate and hindering the improvement of substrate coating quality.

[0031] Reference Figures 1 to 6 According to the flow distribution device of this utility model embodiment, the flow distribution device is provided with a receiving cavity 110, a feeding channel 120 and a plurality of discharging channels 130. The feeding channel 120 is connected to the discharging channel 130 through the receiving cavity 110. The plurality of discharging channels 130 are arranged at intervals around the axis of the receiving cavity 110. The minimum distance between the outlet of each discharging channel 130 and the axis of the feeding channel 120 is equal. In this way, the flow rate and pressure of the slurry flowing out from each discharging channel 130 are equal, which can accurately control the flow rate and pressure of the slurry, thereby improving the coating quality of the substrate.

[0032] For example, the discharge end of the screw pump is connected to the feed channel 120 through the first pipe, and the discharge port of the discharge channel 130 is connected to the corresponding feed hole of the coating die head through the second pipe. The slurry delivered by the screw pump enters the receiving cavity 110 through the feed channel 120, and then is distributed to the corresponding second pipe through multiple discharge channels 130. Since the minimum distance between the discharge port of each discharge channel 130 and the axis of the feed channel 120 is equal, the flow rate and pressure of the slurry flowing out of each discharge channel 130 are equal, which can accurately control the flow rate and pressure of the slurry, thereby improving the coating quality of the substrate.

[0033] In this embodiment, the discharge channel 130 includes a first channel 131, a second channel 132, and a third channel 133 connected in sequence. The first channel 131 is connected to the receiving cavity 110, and the third channel 133 has a discharge port. The axis of the second channel 132 is staggered with the axis of the first channel 131, which can buffer the slurry in the discharge channel 130 so that the flow rate of the slurry in the discharge channel 130 is uniform, which is beneficial to accurately control the flow rate and pressure of the slurry.

[0034] For example, the first channel 131, the second channel 132, and the third channel 133 are arranged in a bent manner. The axis of the second channel 132 is perpendicular to the axis of the first channel 131, and the axis of the third channel 133 is perpendicular to the axis of the first channel 131. In this way, on the one hand, the slurry can flow smoothly through the second channel 132 and the third channel 133, so that the flow rate of the slurry in the discharge channel 130 is uniform, which is conducive to precise control of the slurry flow rate and pressure. On the other hand, the second channel 132 and the third channel 133 are easy to process and the processing accuracy is controllable, thereby meeting the requirements for precise control of slurry flow rate and pressure.

[0035] In this embodiment, the flow distribution device includes a first base 200, a second base 300, and a gasket 400. The gasket 400 is connected between the first base 200 and the second base 300. A receiving cavity 110 is formed between the first base 200, the second base 300, and the gasket 400. A first channel 131 is provided in the gasket 400. A feeding channel 120, a second channel 132, and a third channel 133 are all provided in the first base 200, which facilitates the manufacturing of the flow distribution device.

[0036] For example, the gasket 400 is sandwiched between the first seat 200 and the second seat 300. The second seat 300 is threadedly connected to the first seat 200 by bolts. By setting the first channel 131 on the gasket 400, the structure of the first seat 200 can be simplified, and the flow distribution device can be manufactured more easily.

[0037] In this embodiment, the gasket 400 is provided with a first cavity 111, and a plurality of first channels 131 are respectively connected to the first cavity 111. The first seat 200 is provided with a second cavity 112. The first cavity 111 and the second cavity 112 constitute a receiving cavity 110, which facilitates the production and manufacturing of the flow distribution device.

[0038] In this embodiment, on a cross-section perpendicular to the axis of the receiving cavity 110, the outer contour of the first seat 200 is a regular polygonal structure. The outer contours of the gasket 400 and the second seat 300 are both matched with the outer contour of the first seat 200. The outer peripheral surface of the first seat 200 includes multiple side surfaces, and the discharge port is located on the corresponding side surface, so that the minimum distance between the discharge port of each discharge channel 130 and the axis of the feed channel 120 is equal. In this way, the flow rate and pressure of the slurry flowing out from each discharge channel 130 are equal, which can accurately control the flow rate and pressure of the slurry, thereby improving the coating quality of the substrate.

[0039] For example, in a cross-section perpendicular to the axis of the receiving cavity 110, the outer contours of the first seat 200, the gasket 400, and the second seat 300 are all regular octagonal structures. The outer peripheral surface of the first seat 200 has eight side surfaces, and a discharge port is provided in the middle of each side surface, so that the minimum distance between the discharge port of each discharge channel 130 and the axis of the inlet channel 120 is equal. In this way, the flow rate and pressure of the slurry flowing out from each discharge channel 130 are equal, which can accurately control the flow rate and pressure of the slurry, thereby improving the coating quality of the substrate.

[0040] In this embodiment, a plurality of adjustment components 500 are also included. The plurality of adjustment components 500 are disposed on the second seat 300. The number of adjustment components 500 is equal to the number of discharge channels 130. The adjustment components 500 are used to enter or exit the discharge channel 130 and can adjust the size of the minimum flow cross section of the discharge channel 130, thereby precisely controlling the flow rate and pressure of the slurry.

[0041] In this embodiment, the adjustment component 500 includes a bracket 510, a screwing component 520, and an adjustment block 530. The bracket 510 is located on the side of the second seat 300 away from the first seat 200. The adjustment block 530 is movably located on the second seat 300 to enter or exit the discharge channel 130. The screwing component 520 is rotatably connected to the bracket 510 and threadedly connected to the adjustment block 530 to drive the adjustment block 530 to enter or exit the feed channel 120. This allows adjustment of the minimum flow cross-section of the discharge channel 130, thereby precisely controlling the flow rate and pressure of the slurry.

[0042] For example, the bracket 510 is detachably connected to the second base 300 by bolts, and the screwing part 520 drives the adjusting block 530 to move through the threaded drive, so that the adjusting block 530 enters or exits the feed channel 120, which can adjust the size of the minimum flow cross section of the discharge channel 130, thereby precisely controlling the flow rate and pressure of the slurry.

[0043] As another implementation, the screwing member 520 can also drive the adjusting block 530 to move through a gear and rack transmission structure. For example, the screwing member 520 is provided with a gear, and the adjusting block 530 is provided with a rack. The gear and the rack mesh, which can also drive the adjusting block 530 to move. This is not a limitation.

[0044] As another implementation, the screwing component 520 can also be replaced by a cylinder or motor or other driving component, which can automatically drive the adjusting block 530 to move without manual operation, thereby improving the automation level of the flow distribution device.

[0045] In this embodiment, the flow distribution device also includes a plurality of protective rods 600. The plurality of protective rods 600 are located on the side of the second base 300 away from the first base 200, and a protective space is formed between the plurality of protective rods 600. The plurality of brackets 510 are all located within the protective space, which can reduce the occurrence of collision damage to the screwing part 520, thereby improving the service life of the flow distribution device.

[0046] In this embodiment, the protective rod 600 is detachably connected to the second base 300, which facilitates the assembly of the protective rod 600.

[0047] In this embodiment, the protective rod 600 is provided with an external thread structure, and the second seat 300 has a threaded hole that matches the external thread structure, so that the protective rod 600 and the second seat 300 are threadedly connected. The operation is simple, convenient and quick, and it is easy to assemble the protective rod 600.

[0048] As another implementation, the protective rod 600 can also be detachably connected to the second base 300 by bolting, which is not limited here.

[0049] As another implementation, the protective rod 600 can also be detachably connected to the second base 300 by a snap-fit ​​mechanism, which is not limited here.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
