Embodiment 1

[0044] Embodiment 1: a kind of cast method film production line, such as figure 1 As shown, a frame 1 is included, and the frame 1 includes two transverse rails 11 and two longitudinal rails 12 connected to adjacent transverse rails 11, the longitudinal rails 12 are higher than the transverse rails 11 and part of the longitudinal rails 12 overlap with the transverse rails 11 above.

[0045] The horizontal track 11 is provided with a hard film-making plate, a carrying platform for carrying the film-making plate, a coating mechanism 2 for coating the film-forming solution on the film-making plate, a pre-baking mechanism 3 located above the carrying platform, and a driving pre-drying mechanism. The drying mechanism 3 lifts the first lifting assembly 31 and the oven 4 located downstream of the carrying platform. Wherein the film-making plate is generally glass, the coating mechanism 2 is arranged above the carrying platform, and the frame 1 is provided with a coating power mechan...

Embodiment 2

[0069] Embodiment 2: as Figure 9 As shown, the difference from Embodiment 1 is that the valve 22 also includes a second valve plate 225 that slides along the surface of the partition plate 215 to cover the connecting hole 2151 and is fixed on the base 21 to drive the second valve plate 225 moves the second push cylinder 22624.

[0070] The second valve plate 225 and the first valve plate 222 both can complete the opening and closing action at the same time, and can also complete the opening and closing action respectively; The amount of solution can be kept at a constant liquid level at the bottom, and can also be kept at a constant flow rate; quantitative coating can be completed when they are respectively opened and closed, that is, when the liquid outlet 216 is closed, the solution begins to accumulate in the casting tank 218, Then close the connection hole 2151 when coating.

Embodiment 3

[0071] Embodiment 3: as Figure 10 As shown, the difference from Embodiment 1 or 2 is that the end plate 214 abuts and closes with the bottom plate 211, the end plate 214 is lower than the other side walls of other casting grooves 218, and the ends of the end plates 214 are respectively provided with Inclined inner guide surface and outer guide surface; when closed, the end of the first valve plate 222 abuts against the inner guide surface and the outer guide surface at the same time.

Abstract

The invention discloses a tape casting membrane preparation production line, and relates to the field of membrane preparation equipment. The tape casting membrane preparation production line comprisesa machine frame, wherein a hard membrane preparation plate, a bearing platform, a coating mechanism, a pre-drying mechanism, a drying oven and a conveying system are arranged on the machine frame; the bearing platform is used for bearing the membrane preparation plate; the coating mechanism is used for coating the membrane preparation plate with a membrane preparation solution; the pre-drying mechanism is positioned above the bearing platform; the drying oven is positioned at the downstream part of the bearing platform; the conveying system is used for conveying the membrane preparation plateto the drying oven from the bearing platform and then cyclically conveying to the bearing platform; the coating mechanism is arranged above the bearing platform. The continuous membrane preparation on a hard plate is realized; compared with a traditional flexible conveying belt membrane preparation mode, the device can effectively provide stable, flat and continuous membrane preparation conditions for the coating mechanism; the conditions are provided for preparing thinner and more uniform diaphragms.

Description

technical field [0001] The invention relates to the field of film-making equipment, in particular to a casting film-making production line. Background technique [0002] In electronic components, ceramic insulating substrates, ceramic substrates, dielectric layers, protective layers, and ion diaphragms are usually prepared by tape casting: that is, the raw materials are first made into slurry, and then cast on a tape casting machine after treatment. The film is formed into a green body, which is then dried and fired into shape. [0003] Existing membrane-making equipment is such as, and the Chinese patent that authorized announcement number is CN2779625Y discloses a kind of natural casting method polymer lithium-ion battery diaphragm manufacturing equipment, comprises frame, is provided with transmission base belt on the frame, and the lower surface of transmission base belt is provided with There are a plurality of passing rollers, the right end of the frame is provided wi...
