Description
Technical field
The utility model relates to a kind of equipment improving the accuracy of coated ceramic body or metallic honeycomb bodies, and described ceramic body or metallic honeycomb bodies can be used as the catalyst reducing motor vehicle exhaust gases usually.It is be ready to be delivered to material all in one piece or need to give replacing before coating material all in one piece directly test that the utility model achieves for the coating in coating room.
Background technology
With liquid coated media (so-called aqueous coating) coated with under be referred to as the ceramic body of matrix or material all in one piece or metallic honeycomb bodies/filter during can produce various problem.A kind of feasible program for coated substrates impels the opening of matrix side to be formed with the coated media that can obtain from the below of material all in one piece or top to contact, and pass through the passage extracting liquid coated media of matrix by applying vacuum to the opposite side of matrix.If plan only applies passage in a part of length of passage, so cause due to the inevitable flow behavior occurred when using these deemed-to-satisfy4 means and apply different passages with different length, this is disadvantageous.
If overcoming gravity forces by pressure is pressed in passage by coated media, so just need to check when (normally being checked by sensor) occurs liquid at top when completing passage coating.When applying a part of length of passage, the liquid-column height of the coated media in passage is generally by with sensor (capacitance sensor; Vision sensor; Infrared sensor; Vibrating sensor) directly or indirectly measure and determine.But be in this case equally, if such as coating starts with the irregular coating surface formed in the coating room below material all in one piece, that just may cause coating uneven in the passage of material all in one piece anterior.Especially, if apply fast coating speed and coating tends to be pumped in coating room at short notice time become turbulent flow, that just there will be this situation below.
A kind of preferred coating equipment and method is disclosed in DE102010007499A1, wherein cylindrical carrier all has two end faces, peripheral surface and axial length L, and is horizontally through by the passage that many scribble liquid-liquid coated media from the first end face to the second end face.Described equipment has cylinder that liquid is housed and has piston, and the cylinder that liquid is wherein housed is communicated with tank, is arranged in such a way displacement body in the inside of tank: when piston moves, displacement body is moved pro rata by liquid.Tank is communicated with the coating unit for matrix, and displacement body acts in liquid coated media thus, consequently causes the proportional change (Fig. 1 see this application) of the liquid level of liquid coated media in coating unit.Two sensors are arranged on the phase co-altitude in coating equipment, and object is to check whether the paint surface locations in coating room has reached certain liquid level.
It is evident that the painting method can implementing coating processing in order to disposable coating parts as much as possible is more rapidly preferred.This process should not reduce the accuracy of coating certainly; Particularly when regionality coating material all in one piece, the area end that the accuracy of coating height must be applicable to the coating allowed in monolith channels in the threshold range of ± 5mm, preferably in ± 3mm or even less threshold range.
If coating speed increases, so the filler of coating room must carry out in the short period of time.This just causes the filler that the turbulent flow in the coating room of the characteristic of bearing aqueous coating and erecting tools is possibly stronger, causes irregular coating surface in coating room or cause to occur bubble significantly around the coating near coating room wall portion.If coating processing continues, this just will also cause irregular coating anterior in the passage of material all in one piece, and therefore will increase the coated substandard risk of parts.
Therefore target of the present utility model is to provide a kind of equipment and using method thereof for reducing above-mentioned adverse effect when performing the coating of automotive catalysts.Especially, which coating surface described equipment directly and easily should be able to distinguish between the coating surface in coating room relative to out-of-flatness or slightly to rise and fall may be maybe smooth containing those coating surfaces alveolate.If coating continue, so out-of-flatness or slightly rise and fall maybe may containing alveolate coating surface will make the mistake coating parts.

Detailed description of the invention
A kind of favourable process for applying described matrix is realized by the utility model.Can check whether the coating be introduced in coating room 100 has been ready to be accepted by attached material all in one piece 121 by equipment of the present utility model.Coating seems out-of-flatness or comprises bubble in some cases, as by the agency of (Fig. 2).If coating processing continues, this forms disturbed coating by causing in the passage 110 of material all in one piece.For the coating processing only performed in a part of length of material all in one piece, this causes the different zone length for different passage in itself, thus correspondingly obviously increases the coated substandard risk of material all in one piece.If coating speed increases further, and the speed therefore introducing coating in coating room increases further, and this situation even can become more obvious.
But, if the surface exhibits being pumped into the coating 130 in coating room is smooth outward appearance (Fig. 1), so coating processing is just obtained by coating 113 or even the material all in one piece 121 of humidity, and in the passage 110 of material all in one piece, form the coating 132 of equal area width.At this, equipment in the utility model can carry out detecting and distinguishing between the surface of smooth and out-of-flatness just before will applying material all in one piece in coating room 100 or disturbed coating 130, coating processing can produce the material all in one piece of mistake coating and must destroy subsequently or even cause client reject before interrupt in time.On the contrary, if necessary, after emptying coating room along backflow direction 118, can be introduced by pipeline 116 and start the new filler of coating room 110 along filler flow direction 117 in advance, and if equipment shows smooth coating surface 130 in coating room, so advantageously just material all in one piece can be applied at this moment.
The measurement of the apparent height of the coating in coating room 100 is implemented by the sensor 123-125 being connected to CPU 140.From below 116,117 in coating room 100 during pumping coating, first coating arrive the sensor 124 of coating room 100 compared with low side, and then, in the ideal case, sensor 124 is contacted by liquid coating with 125 simultaneously.Therefore, processing unit 140 detects the signal from two sensors within certain still very short time period.Whether smooth in order to check the surface of coating, described at least the first and second sensors preferably around coating room with Distance positioning maximum to each other.Contribute to the possibility maximizing flat appearance coating really being detected like this.When have such as have three or four sensors more than two higher sensors, be similar to the first and second sensors, described sensor is respective but the distribution on identical height advantageously realizes according to these rules in coating room 100.Therefore, more three sensors around coating room 100 with the angle orientation of 120 degree to each other, by that analogy.Processing unit 140 is connected to like these more sensor class.
