Embodiment
Relevant the technical content and a detailed description of the present utility model, existing accompanying drawings is as follows.
The utility model provides a kind of coating shower nozzle with protector; as extremely shown in Figure 4 in Fig. 2; coating shower nozzle 20 comprises the narrow slit structure 22 for coated substrates 40; also comprise protector 21; protector 21 is arranged on the coating front side of shower nozzle 20 on traffic direction; and protector 21 has inlet mouth 211, air flue 213 and the air outlet 212 that is interconnected, and the opening direction of air outlet 212 deviates from the Way out of narrow slit structure 22.Concrete, described protector 21 can be positioned at the bottom of the front side of coating shower nozzle 20 on traffic direction.
Wherein, substrate 40 can for be glass substrate, quartz base plate etc. based on the underlay substrate of inorganic materials, can be also the underlay substrate that adopts organic materials.Correspondingly, the coating carried out of narrow slit structure 22 can include but not limited to gluing.
When the substrate 40 on 20 pairs of base stations 30 of coating shower nozzle is coated with, the coating protector 21 of shower nozzle 20 in the front side on traffic direction utilizes pressurized gas (such as CDA) to blow away foreign matter (particle, dust etc.) on substrate 40, and the Way out that deviates from narrow slit structure 22 due to the opening direction of air outlet 212, the opening direction that is air outlet 212 is not the Way out towards narrow slit structure 22, so, can guarantee that the foreign matter that blows away is also away from the Way out of narrow slit structure 22; Afterwards, be positioned at substrate 40 coatings after 22 pairs of cleanings of narrow slit structure at protector 21 rears, like this, greatly reduce the generation of the fraction defective that causes due to foreign matter.
As shown in Figure 4, the aperture of air outlet 212 can be less than or equal to the caliber of air flue 213, and the aperture of air outlet 212 is less than the aperture of inlet mouth 211.The aperture of inlet mouth 211 is larger, is convenient to the input of CDA; And the aperture of air outlet 212 is less, makes air-flow more concentrated when ejection, and the effect of getting rid of foreign matter is better.In the utility model, do not limit concrete size and the shape of inlet mouth 211, air flue 213 and air outlet 212, the setting of its size can guarantee that CDA blows away smoothly foreign matter and can wounded substrate 40 not get final product.In addition, also do not limit for parameters such as the flow of the CDA of inlet mouth 211, incidence rates, as long as guarantee to blow away foreign matter.And the position of inlet mouth 211 also can be set as required.
In addition, the angle between air outlet 212 and substrate 40 is between 45 degree are spent to 90.Different from the distance of narrow slit structure 22 outlets along with air outlet 212, between air outlet 212 and substrate 40, the setting of angle also can respective change.For example, when the distance of air outlet 212 and narrow slit structure 22 outlets became large, this angle also can suitably increase, with can not cause foreign matter that air-flow blows afloat backward the Way out of narrow slit structure 22 (namely towards) motion get final product.
Preferably, coating shower nozzle 20 is made by stainless steel; In addition, coating shower nozzle 20 is formed in one, and for example can adopt the casting mode to form inlet mouth 211, air flue 213 and the air outlet 212 of narrow slit structure 22 and protector 21.
Preferably, coating shower nozzle 20 also comprises the sensor (not shown) for detection of foreign matter, specifically, after substrate 40 is placed into base station 30, and before coating shower nozzle 20 begins to be coated with, at first utilize this sensor to carry out foreign matter to substrate 40 and detect, as finding foreign matter, begin again coating after removing.Because of design reasons, the installation site of this sensor is not limited.This sensor can be arranged on any suitable position of coating shower nozzle 20, even is arranged on outside coating shower nozzle 20 for example all can on base station.
The utility model also provides a kind of coating machine with above-mentioned coating shower nozzle, and the coating shower nozzle of this coating machine adopts structure and the use-pattern thereof of above-mentioned coating shower nozzle 20, does not repeat them here.
The above is only preferred embodiment of the present utility model, is not be used to limiting protection domain of the present utility model.
