Abstract
A dimension measurement apparatus is disclosed, including a carrier plate and a line scan camera. The carrier plate is configured to carry a to-be-measured item. The line scan camera is disposed opposite to the carrier plate along a first direction and configured to photograph the to-be-measured item. The line scan camera is configured to be movable relative to the carrier plate along a second direction, and the first direction is perpendicular to the second direction. The dimension measurement apparatus can improve the shooting efficiency.
Claims21
A dimension measurement apparatus, comprising:
- a carrier plate, configured to carry a to-be-measured item, the to-be-measured item is an electrode assembly comprising an electrode body and two tabs, the electrode body comprising a top region and a bottom region disposed opposite to each other, the two tabs extending out from the top region;
- and
- a line scan camera, disposed opposite to the carrier plate along a first direction and configured to photograph the to-be-measured item, wherein the line scan camera is configured to be movable relative to the carrier plate along a second direction, and the first direction is perpendicular to the second direction,
- wherein a plurality of the line scan cameras are disposed, and the plurality of line scan cameras comprise a first line scan camera and a second line scan camera,
- wherein the first line scan camera and the second line scan camera are arranged along a third direction, and the third direction intersects the second direction and is parallel to an arrangement direction of the top region and the bottom region.
A dimension measurement apparatus comprising:
- a carrier plate, configured to carry a to-be-measured item;
- and
- a line scan camera, disposed opposite to the carrier plate along a first direction and configured to photograph the to-be-measured item, wherein the line scan camera is configured to be movable relative to the carrier plate along a second direction, and the first direction is perpendicular to the second direction,
- wherein a movement speed of the line scan camera along the second direction is v, satisfying:
- 450 mm/s<v<600 mm/s.
A dimension measurement apparatus comprising:
- a carrier plate, configured to carry a to-be-measured item;
- a line scan camera, disposed opposite to the carrier plate along a first direction and configured to photograph the to-be-measured item, wherein the line scan camera is configured to be movable relative to the carrier plate along a second direction, and the first direction is perpendicular to the second direction;
- a shelf, wherein the carrier plate and the line scan camera are disposed on the shelf;
- and
- a backlight source connected to the shelf, wherein the carrier plate comprises a carrier surface configured to carry an electrode assembly and a back surface opposite to the carrier surface, and the backlight source is located on a side of back surface, the side facing away from the carrier surface.
