Embodiment 1

[0033] Such as figure 1 As shown, this embodiment provides a support table with an automatically adjustable inclination angle, including a controller, a support plate 11, a base 12 and at least three telescopic cylinders 13, the base 12 is arranged horizontally, and the support plate 11 is arranged Above the base 12, a plurality of the telescopic cylinders 13 are vertically installed on the base 12 and distributed in concentric circles on the base 12, and each of the telescopic cylinders 13 is located on the base 12. 12 can slide radially along concentric circles, the telescopic ends of a plurality of said telescopic cylinders 13 are all upward, and are all connected with the lower end of said support plate 11 through universal balls 14, each of said telescopic cylinders 13 There is a telescopic length measuring device for measuring the elongation length of the telescopic cylinder, and a plurality of the telescopic length measuring devices and a plurality of the telescopic cyl...

Embodiment 2

[0043] Such as Image 6 As shown, the present embodiment provides a laser chip detection device, including an optical receiver 2 (belonging to the prior art, not described in detail here) and a support table 1 with an automatically adjustable tilt angle as described in Embodiment 1, so The light receiver 2 is set and suspended on the side above the support plate 11 (the light-receiving end thereof is tilted downward and faces the support plate downward), and the support plate 11 is used to place the laser chip, so The support table 1 with automatically adjustable inclination angle is used to adjust the inclination angle of the support plate 11 so that the laser beam emitted by the laser chip is aligned with the light receiver 2, or adjust the support plate 11 to the level so that Reset has a simple structure and a high degree of automation. Wherein, the support plate is provided with a mounting seat for the laser chip (which is the prior art, and will not be described in deta...

Abstract

The invention discloses an inclination-angle-automatically adjustable supporting table and a laser chip detection device. The inclination-angle-automatically adjustable supporting table comprises a controller, a supporting plate, a base and at least three telescopic cylinders, the base is horizontally arranged, the supporting plate is arranged above the base, the telescopic cylinders are vertically installed on the base and are distributed on the base in a concentric circle mode, each telescopic cylinder can slide on the base in the radial direction of the concentric circle, the telescopic ends of the telescopic cylinders face upwards and are connected with the lower end of the supporting plate through universal balls, and each telescopic cylinder is provided with a telescopic length measuring device used for measuring the extension length of the telescopic cylinder, the multiple telescopic length measuring devices and the multiple telescopic cylinders are electrically connected with the controller, and the controller adjusts the telescopic amount of the multiple telescopic cylinders according to the measured values of the multiple telescopic length measuring devices so as to adjust the inclination angle of the supporting plate. Thus, the automation degree is high, and the inclination angle of the supporting plate can be flexibly adjusted.

Description

technical field [0001] The invention belongs to the field of chip detection equipment, and in particular relates to a support platform with an automatically adjustable tilt angle and a laser chip detection device. Background technique [0002] The parameters to be measured of the laser chip generally include power, peak wavelength, pulse frequency, beam width, divergence angle, etc. When performing laser chip testing, it is necessary to ensure that the angle and height of the test bench carrying the laser chip are adjustable, so that the laser to be tested can reach the correct position of the test device at the correct angle, otherwise system errors will be introduced, and even the test cannot be completed. For example, if the laser optical path is not perpendicular to the sensor, the measured spot size will be too large, which will affect the measurement results of the beam width and divergence angle; what's more, if the optical fiber is used as the receiver, its effective...
