The invention relates to the technical field of manufacturing of discrete semiconductor devices, and discloses a detection device for manufacturing a cylindrical capacitor of a discrete semiconductordevice, which comprises a base, an arc-shaped iron sheet is arranged on the left side in a fixed disc, a coil corresponding to a detection needle is arranged on the right side of the arc-shaped iron sheet, and a rectangular magnetic block is arranged on the right side in the fixed disc. The upper portion of the threaded disc is connected with a sliding magnetic block, a guide pipe is arranged on the upper side of the main rotary disc, and an arc-shaped magnetic block is arranged on the upper left portion of the guide pipe. The main rotary disc rotates to drive the driven disc to rotate and rubwith the fixed disc, so that the driven disc is driven to rotate through friction force, the driven disc drives the capacitor to rotate through the supporting rod on the driven disc, it is guaranteedthat the capacitor rotates by a circle within the range of the corresponding arc-shaped iron sheet, and the pins and the detection pins are further communicated once. Therefore, the damaged capacitoris prevented from being affected by the magnetism of the arc-shaped iron sheet, and whether the capacitor is powered on or not is detected in front of the left of the main turntable.
Description
technical field [0001] The invention relates to the technical field of manufacturing semiconductor discrete devices, in particular to a detection device for manufacturing cylindrical capacitors of semiconductor discrete devices. Background technique [0002] Semiconductor discrete devices generally refer to semiconductor crystal diodes, semiconductor triodes, referred to as diodes, triodes and semiconductor special devices. In terms of product applications, the growing demand for power conversion and power management of electronic complete products directly promotes the development of power transistor products. . With the global economy's emphasis on energy conservation and environmental protection, power semiconductor technology will be further developed, thereby driving the rapid growth of the discrete device market. [0003] Among them, in the production and manufacture of cylindrical capacitors, it is necessary to detect whether the cylindrical capacitors are energized....
