The present disclosure relates to a high-precision automatic weighing device for powder samples, including a three-dimensional moving track and a working area, wherein the three-dimensional moving track includes a horizontal length track, a vertical track and a horizontal width track, the vertical track being slidingly connected to the horizontal length track, the horizontal width track being slidingly connected to the vertical track; the horizontal length track is arranged on one side of the working area, and a cleaning area, a sample storage area and a weighing area are provided in sequence along the horizontal length track within the working area; a series of slideways are connected to a mechanical claw for grabbing a sample tube in the sample storage area, a fine-tuning sample releasing mechanism to release samples in trace amounts, a sample head clamping part for mounting or dismounting of a sample head, and a sample loosening pestle.

High-precision automatic weighing device for powder samples

Embodiments of the present invention provide a detaching tool The detaching tool includes a detaching plate. A detaching part of the detaching plate is adapted to be inserted between a printed circuit board and a backlight source back plate. The detaching tool is configured to separate and detach the PCBA, adhered to the backlight source back plate, from the backlight source back plate.

Detaching tool

A separation device for a backlight source is provided. The separation device includes a machine table, at least one separation platform, where each separation platform is located above the machine table and secured at a fixed position relative to the machine table and is configured to support a display module and secure a backlight source of the display module thereon; a plurality of guide columns arranged perpendicular to the machine table, at least one adsorption mechanism arranged in a one-to-one correspondence with the at least one separation platform, where each adsorption mechanism is arranged at a side of the corresponding separation platform away from the machine table and configured to adsorb a display screen of the display module on the corresponding separation platform, and a driving unit configured to drive each adsorption mechanism to move in the lengthwise direction of the plurality of guide columns.
