Automatic positioning error correction device used for plastic-shell low-voltage electric appliance integration characteristic detection

Abstract

The invention relates to an automatic positioning error correction device used for plastic-shell low-voltage electric appliance integration characteristic detection. The device comprises a clamping mechanism and a detection mechanism which are adjacent to each other. The clamping mechanism comprises a first frame, a support plate horizontally arranged on the first frame and a tooling base plate which can be rotated relative to the support plate. The first frame is provided with one or more hinge flip components which compact and position the rotated tooling base plate. Each hinge flip component comprises a first air cylinder, an air cylinder joint connected to an output terminal of the first air cylinder, a pressing rod whose one end is rotatably connected to the air cylinder joint and a first hinge moving block, wherein one end of the first hinge moving block is rotatably connected to the pressing rod and the other end is rotatably connected to a fixing plate which supports the first air cylinder. The detection mechanism comprises a second frame and a test framework arranged on the second frame. The test framework is provided with one or more groups of probe mechanisms, a CCD mechanism used for capturing a target position and a targeting laser mechanism, wherein the probe mechanisms move along an X axis and an Z axis; the CCD mechanism can move along the X axis, a Y axis and the Z axis; and the targeting laser mechanism can move along the X axis.

Description

technical field [0001] The invention relates to a device in a characteristic detection production line of low-voltage electrical appliances with molded cases, in particular to an automatic positioning and deviation correction device for comprehensive characteristic detection of low-voltage electrical appliances with plastic cases. Background technique [0002] With the development and application of high technology, the parameter testing equipment for comprehensive characteristic testing has become an integrated product of light, machinery and electricity, and is developing in the direction of high speed, unattended, general purpose and high quality. The detection has become an indispensable function. The parameters of comprehensive characteristic detection include pull-in and release voltage; coil holding current; contact opening distance and overtravel; three-phase synchronous difference (opening / closing time); contact bounce time; loop resistance test; auxiliary contact p...

AI Technical Summary

Problems solved by technology

[0004] The detection of open distance and overtravel requires a high-speed DSP acquisition module (TI TMS320F28335) to acquire displacement (generally using a laser sensor, such as KEYENCE LK-H150). Due to manual clamping on the position of the assembly line tray, it is impossible to ensure uniformity, and the assembly line is generally Need to adapt to a wide variety of products, so the method of mechanical positioning cannot guarantee that the laser will hit the target every time
