Problems solved by technology

However, the suction nozzle of the existing suction pen is perpendicular to the body of the pen, which makes the suction nozzle not fully engage with the horizontal crystal grains when in use, requiring greater energy consumption (vacuum pressure) to complete the suction.

Embodiment Construction

[0014] The present invention as figure 1 As shown: it includes a hollow pen holder 2, an air pipe 1 connected to the tail end of the pen holder 2, and a suction nozzle 6 arranged at the head end of the pen holder 2, and a press-type air valve is provided at a distance of 2-4 cm from the suction nozzle 6 on the shaft of the pen holder 2, The end surface of the suction nozzle 6 forms an included angle of 45-70° with the horizontal plane.

[0015] It also includes a tapered nib 9 , which is fixedly connected to the suction nozzle 6 , and is pivotally connected to the pen holder 2 in an airtight manner, so that the nib 9 can rotate relative to the pen holder 2 .

[0016] The push type air valve includes a cylindrical button 8 with a radial through hole 7 and a spring 4, and the penholder 2 is provided with a circular air valve chamber that is transverse to the section of the penholder 2, and the air valve chamber is set There are an upper hole 3 and a lower hole 5, the button 8 i...

Abstract

The invention relates to a grain sorting suction pen, belonging to improvement of a sorting suction pen. The invention can control the operating airflow, accords with the operating habit of people and reduces the energy consumption. The grain sorting suction pen comprises a hollow pen holder, an air tube connected to the tail end of the pen holder and a suction nozzle arranged on the head of the pen holder. A press-type air valve is arranged at 2-4cm of the pen holder body away from the suction nozzle; and an included angle of 45-70 degrees is formed between the end surface of the suction nozzle and the horizontal plane. In order to save energy and reduce emission, the suction pen is provided with a switch for controlling connection and disconnection of the operating airflow and the pen holder is under the normally-closed state in the normal state so as to reduce the energy consumption of a vacuum press. Besides, the end surface of the suction nozzle is arranged to be an inclined surface in order to meet a general condition that a certain degree is formed between the pen holder and the horizontal plane for operators, therefore the suction nozzle and a wafer are sucked more efficiently, and the phenomenon of improving the energy consumption because of long-time air leakage before suction is avoided.

Description

technical field [0001] The present invention relates to the improvement of sorting suction pen. technical background [0002] In the microelectronics industry, a single wafer is divided into several tiny grains. When the yield rate is low and the defective products are scattered, it is very important to sort the good and defective products in an effective, fast and energy-saving method. Since a single grain is very small, the minimum can reach 38mil (mil: one-thousandth of an inch, 1000mil=25.4mm), and the grain is easily polluted by the surrounding air, so it is not possible to directly touch the grain with good electrical properties with your fingers . Generally, the defective products are marked by testing equipment, and then the defective products are sorted out manually by using a suction pen after splitting. [0003] Adopt self-made suction pen on the applicant's production line at present, be to adopt the shell of the ballpoint pen that reclaims to scrap and drill a...
