Description

Powered suction air knife

This creation is about a kind of etching power-type suction air knife. It belongs to the field of metal etching technology. It has the effect of removing the pool effect, producing thin plate or soft board performance, avoiding board skew or card board to improve product quality.

Etching refers to the operation of removing all or part of a metal surface by the erosive action of a chemical agent. At present, the etching industry is widely used in the electronics industry, such as semiconductor device wafers, manufacturing of circuit boards, and the like. Taking China's etching patent as an example, the publication No. M386597 is used for the stage of the flexible substrate etching process (refer to the patent announcement on August 11, 2010), and the stage is applied to the flexible substrate roll to roll circuit. In the etching process, in addition to supporting the flexible substrate under the etchant spray, the soft substrate can form a lower curved surface on both sides of the intermediate protrusion, thereby making the etchant sprayed on the curved flexible substrate Increase the fluidity to reduce the phenomenon of pools accumulated in the center of the flexible substrate, so that the flexible substrate can be etched into any fine lines or patterns to achieve a comprehensive uniform etching effect. An improved structure of the etching machine No. M296469 (refer to the patent publication of August 21, 2006), which comprises a body, a sprayer, a storage tray and a linear or curved track, and the upper or lower end of the body is provided with an etchable spray a liquid guiding member, which is disposed on the upper or lower end of the body, and includes a connecting pipe and a plurality of branching pipes extending outwardly from one side or both sides, wherein the plurality of branching pipes are at an angle with a horizontal displacement direction of the storage tray, The storage tray is disposed inside the body, and has a seat body with a rotating shaft below or above, and has a top or bottom thereon a plurality of protective films affixed to the object to be etched for etching, the linear or curved track being disposed in the body, and having grooves for linearly moving the trays thereon or below, thereby removing the tray of the etching machine Rotate outside and make a moderate linear or curved displacement, so that the etching spray is always at right angles to the object to be etched, and because the object to be etched is left and right, the dead angle can be eliminated, so that the etching operation is all-round and the upper view of the object to be etched The size of the pattern is more uniform. Since the etchant sprayed by the nozzle is easy to form a pool on the surface of the etchant, which is called a pool effect, the pool effect tends to cause uneven etching, and how to avoid the pool effect is a problem that various industries need to overcome.

The author of the creative researcher previously created the M406253 etching device patent, in the etching process, using the principle of the difference in flow rate to form a similar vacuum attraction, which will spray the etching liquid on the surface of the object to be etched, using this attraction, Take it away from the surface of the object to be etched to avoid the pool effect. The utility model mainly comprises a plurality of spray nozzles, each spray nozzle pipeline is connected with an injection power source for supplying the spray nozzle etching liquid, and further comprises a plurality of suction air cutters, each of which attracts the air knife pipeline to provide attractiveness for attracting the wind knife attraction. The device and the circulating power source are characterized in that: the suction device comprises a three-way pipe, the three-way pipe has a first pipe body and a second pipe body arranged in a straight line, and the first pipe body and the second pipe body have a third pipe body connected to the outside, the first pipe body is connected to the circulating power source, the second pipe body is connected to the etching liquid tank, the third pipe body is connected to the suction air knife, and the first pipe body is externally large and small Conical mouth, the second tube body has a conical opening with small inside and outside, which has excellent attracting effect and can effectively remove the pool effect. It has been highly praised by the industry since its launch. However, due to the vacuum etching machine in the production of thin plates (or soft boards), because of the attraction of the vacuum, the thin plate (or soft board) is sucked up and adhered to the air knife, causing the thin plate (or soft board) to be skewed or even the card board. In the absence of this, the creation solves the limitation that the vacuum etching machine cannot produce thin or soft plates, and the etching device patent is more perfect.

This creative researcher has been continuously researching, in view of the lack of conventional technology. After the improvement, the creation of this creation was successful and made known to the world.

The reason is that the main purpose of this creation is to provide a "powered suction air knife", which mainly includes a body having a pipeline inside the body, one end of the pipeline is closed, and the other side is connected with a suction device, and the seat body has a suction side with respect to the suction side. a plurality of gaps are connected to each other, and each of the gaps is connected to the suction body. The suction body has at least one passage, one end of each passage communicates with the gap of the seat body, and the other end has a suction port, and each suction port has a smaller gap than the seat body, and the foregoing suctions are attracted. The main body is provided with a transmission shaft parallel to the seat body, and the transmission shaft is coupled to the main transmission mechanism of the machine and is driven by the transmission shaft. The transmission shaft is provided with a wheel on each suction body side, and each wheel piece rotates with the transmission shaft, and The wheel piece protrudes from the lower edge of the suction body, and the creation attracts the air knife structure in addition to having a better attraction effect, and can effectively remove the pool effect, and can also press the rotating wheel to suppress the object to be etched, so that the object to be etched is to be etched. When the board is a thin board or a soft board, the object to be etched is not adhered to the attracting body due to the vacuum attraction, which causes the card board or the board to be skewed, thereby solving the vacuum etching machine. Limiting the production of flexible sheet or plate.
