Description

Technical Field

[0001] The utility model relates to a material receiving device, in particular to a material receiving device for reducing surface impurities of wafer-type electronic ceramic blanks. Background Art

[0002] At present, in the production process of wafer-type electronic ceramic components such as ceramic capacitors, varistors, NTC / PTC thermistors and other electronic ceramic components, the manufacturing of ceramic blanks is a very important link. Generally, ceramic blanks need to go through two processes: die pressing and die pressing forming. There will be some burrs and impurities on the ceramic blanks after die pressing forming.

[0003] After the ceramic blanks are die pressed and formed, they need to be transported in batches. Usually, each varistor blank is arranged vertically, and is transported in a strip-shaped plastic pipe with the notch facing up. The material of this strip-shaped plastic pipe is polyvinyl chloride (PVC); however, during the transportation process, the friction between the edge of the ceramic blank and the inner wall of the strip-shaped plastic pipe is relatively large. The burrs and impurities on the ceramic blank are likely to rub against the inner wall of the strip-shaped plastic pipe, causing the burrs and impurities on the ceramic blank to fall into the strip-shaped plastic pipe. As the strip-shaped plastic pipe is used for a long time, the impurities in it accumulate more and more, which instead increases the impurities on the surface of the ceramic blank and affects the use of the ceramic blank. Summary of the Utility Model

[0004] The problem to be solved by the utility model is to provide a material receiving device for reducing surface impurities of wafer-type electronic ceramic blanks, which can reduce the surface impurities of wafer-type electronic ceramic blanks.

[0005] In order to solve the above technical problems, the technical scheme adopted by the utility model is as follows:

[0006] A material receiving device for reducing surface impurities of wafer-type electronic ceramic blanks, including a strip-shaped pipe with the notch facing up and a vibration mechanism capable of driving the strip-shaped pipe to vibrate. The strip-shaped pipe is arranged to gradually incline downward from front to back. It is characterized in that: it further includes a negative pressure dust suction mechanism. The negative pressure dust suction mechanism is provided with a plurality of dust suction nozzles. A plurality of ash filtering through holes are provided on the trough bottom of the strip-shaped pipe from front to back. The number of ash filtering through holes is the same as that of the dust suction nozzles and they correspond one by one. The dust suction port of each dust suction nozzle is located below the corresponding ash filtering through hole; the material of the strip-shaped pipe is stainless steel.

[0007] Generally, the above vibration mechanism is a vibrator.

[0008] During material receiving, the negative pressure dust suction mechanism is turned on. First, the circular ceramic blanks after die pressing are guided from the die pressing and forming equipment to the inlet of the strip-shaped pipeline by gravity, and then the strip-shaped pipeline is vibrated by the vibration mechanism to drive each circular ceramic blank to be neatly arranged and conveyed backward along the inclined direction of the strip-shaped pipeline. Since multiple ash filtering through holes are provided at the bottom of the groove of the strip-shaped pipeline from front to back, during the conveying process, the burrs and impurities falling from the ceramic blanks will fall into the corresponding dust suction nozzles through the ash filtering through holes with the vibration of the strip-shaped pipeline, and the burrs and impurities will be sucked away by the negative pressure dust suction mechanism, filtering out the impurities on the surface of the ceramic blanks to prevent the accumulation of more and more impurities in the strip-shaped pipeline during long-term use. Also, since the pipe wall of the strip-shaped pipeline made of stainless steel is relatively smooth, it can reduce the friction between the edges of the ceramic blanks and the pipe wall of the strip-shaped pipeline, facilitating the maintenance of the integrity of the edges of the circular ceramic blanks and the conveying of the circular ceramic blanks.

[0009] In the preferred solution, the negative pressure dust suction mechanism further includes a dust suction box, a dust suction pipe, an air extraction pipe, and an air extraction pump. One end of the dust suction pipe is connected to the air inlet of the dust suction box, the air outlet of the dust suction box is connected to the air inlet end of the air extraction pump through the air extraction pipe, and the dust suction pipe is provided with dust suction holes corresponding to the multiple ash filtering through holes. Each dust suction nozzle is respectively installed in the corresponding dust suction hole. When sucking dust, the air extraction pump is turned on, and air is extracted successively through the air extraction pipe, the dust suction box, the dust suction pipe, and each dust suction nozzle, forming a negative pressure at the dust suction port of each dust suction nozzle to adsorb the impurities passing through the ash filtering through holes downward into the dust suction box.

[0010] In a further preferred solution, a filter screen is provided at the air outlet of the dust suction box. Using the filter screen can prevent the dust in the dust suction box from entering the air extraction pipe and prevent the dust from polluting the air extraction pipe and the air extraction pump.

[0011] In the preferred solution, the cross-section of the strip-shaped pipeline is semi-circular. Through this setting, the strip-shaped pipeline with a semi-circular cross-section is more matched with the outer edge of the circular electronic ceramic blank, enabling the outer edge of the circular electronic ceramic blank to better contact the inner wall of the strip-shaped pipeline, making the conveying process more stable and efficient.

[0012] Compared with the prior art, the present utility model has the following advantages:

[0013] The present utility model vibrates and conveys the circular electronic ceramic blanks, and then adsorbs and collects the impurities in the strip-shaped pipeline by negative pressure, which can reduce the impurities on the surface of the circular electronic ceramic blanks, keep the surface of the ceramic blanks clean, and improve the production quality and reliability.

[0019] During material receiving, the negative - pressure dust - suction mechanism 1 is turned on.

One end of the dust - suction pipe 13 is connected to the air - suction port of the dust - suction box 12, the air - outlet of the dust - suction box 12 is connected to the air - inlet end of the air - extraction pump 15 through the air - extraction pipe 14. A plurality of dust - suction holes 131 corresponding to the ash - filtering through - holes 21 are provided on the dust - suction pipe 13, and each dust - suction nozzle 11 is respectively installed in the corresponding dust - suction hole 131. During dust - suction, the air - extraction pump 15 is turned on, and air is extracted in sequence through the air - extraction pipe 14, the dust - suction box 12, the dust - suction pipe 13, and each dust - suction nozzle 11, forming a negative pressure at the dust - suction ports of each dust - suction nozzle 11, and adsorbing the impurities passing through the ash - filtering through - holes 21 downward into the dust - suction box 12.

[0021] A filter screen 16 is provided at the air outlet of the dust suction box 12. Using the filter screen 16 can prevent the dust in the dust suction box 12 from entering the air extraction pipe 14, and prevent the dust from polluting the air extraction pipe 14 and the air extraction pump 15.

[0022] The cross-section of the strip-shaped pipe 2 is semi-circular. Through this setting, the strip-shaped pipe 2 with a semi-circular cross-section is more matched with the outer edge of the wafer-type electronic ceramic blank, and can make the outer edge of the wafer-type electronic ceramic blank better contact with the inner wall of the strip-shaped pipe 2, making the conveying process more stable and efficient.
