The invention relates to a device for detecting the height of an SMD LED lamp on an LED lamp bar. The device for detecting the height of the SMD LED lamp on the LED lamp bar comprises an L-shaped support, wherein the support comprises a locating platform which is arranged horizontally and used for containing the LED lamp bar, and a detecting frame perpendicularly connected with the locating platform. The detecting frame is provided with a detecting mechanism, the detecting mechanism faces the LED lamp bar and comprises a lengthwise detecting plate, the detecting plate is provided with multiple detecting blind holes which face the LED lamp and correspond to the LED lamp in position, a horizontal elastic piece is arranged at the position, close to the bottom of each detecting blind hole, in the blind hole, each elastic piece is provided with a first contact chip, a second contact chip is arranged on the bottom of each detecting blind hole, and all the second contact chips are electrically connected with indicator lights. According to the device for detecting the height of the SMD LED lamp on the LED lamp bar, whether the first contact chips make contact with the second contact chips is utilized to reflect detection results through the indicator lights, detecting personnel can detect the LED lamps which do not meet height requirements rapidly and conveniently, the structure is simple, and the detection precision is high.
Description
technical field [0001] The invention relates to a height detection device, in particular to a device for detecting the height of a patch LED lamp on an LED light bar. Background technique [0002] In order to ensure the qualified rate of the LED light bar, the LED light bar manufacturer needs to test the LED light bar before leaving the factory, which includes testing the height of the patch LED light on the LED light bar, because the LED on the LED light bar The lights are pasted on the light strips in batches by a placement machine, and it is inevitable that there will be poor contact between the LED lights and the light strips. After testing, when the height of the SMD LED light on the light bar is 3.4mm, the contact state is the best, and the service life of the LED light bar is the longest. When the placement machine sticks the LED light, it will produce ±0.1mm Tolerance, and the tolerance of the LED light allowed on the light bar is -0.1mm, that is, when the height of...
