Small-sized electric vacuum pen

Abstract

The invention relates to a small-sized electric vacuum pen. The pen comprises a suction head, a handle cylinder, an upper handle, a lower handle, an air suction pump, a button and a power source assembly. The power source assembly is composed of a battery and a switch component; the switch component is connected with the air suction pump and the battery, so that an integral structure can be formed, and the integral structure is installed in an inner cavity formed by the handle cylinder, the upper handle and the lower handle; the switch component is composed of the button, a battery positive electrode wire, an air suction pump wire, and a spring seat, wherein the button is connected with a button spring and a rubber pad, the battery positive electrode wire is connected with a positive electrode conductive sheet and is welded on a conductive sheet, the air suction pump wire is connected with an air suction pump conductive sheet and is welded onto the positive electrode of the air suctionpump, and the spring seat is provided with a battery negative electrode spring and is welded on the negative electrode of the air suction pump; an air suction three-way shaft is matched with the button; one end of the air suction three-way shaft is connected with the air suction pump; and the other end of the air suction three-way shaft passes through via holes at end portions of the upper handleand the lower handle and is connected with the suction head provided with a suction cup. The small-sized electric vacuum pen can be conveniently assembled without tools. The power source assembly andthe air suction pump are directly installed in the electric vacuum pen, and therefore, the small-sized electric vacuum pen has the advantages of compact structure, small size, easiness in carrying and convenient, fast, comfortable and safe operation. Different suction cups can be exchanged, so that the small-sized electric vacuum pen can absorb electronic parts of different sizes.

Description

technical field [0001] The invention relates to a small electric suction pen which is a special tool for picking up and placing small parts such as lens optical elements and electronic parts during the production process of electronic products, and carrying a convenient and easy-to-use special tool. Background technique [0002] In the production process of large-scale electronic products, automatic placement machines are generally used to install surface components, but in the process of new product testing and small batch production, manual placement is still required. In order to improve installation efficiency , To ensure product quality, it is necessary to use some special tools that are easy to operate. [0003] Patent No. 201510174272.8 "A Vacuum Suction Pen with Telescopic Suction Head" and Patent No. 201620968643.X "A Vacuum Suction Pen", although they both provide a light weight, fast mounting speed, and are not easy to cause false welding and false welding Phenom...
