Detection apparatus and battery production device

A detection apparatus for detecting battery deformation, comprising:

• a scanning frame;
• a radiation source connected to the scanning frame;
• a detector connected to the scanning frame, wherein the detector is opposite an emission port of the radiation source;
• and
• a carrying platform located between the radiation source and the detector, wherein the carrying platform is configured to hold a to-be-tested battery on a carrying surface;
• wherein the radiation source and the detector are arranged for rotating around a same rotation axis, a rotation direction of the radiation source is the same as a rotation direction of the detector, such that during rotation, the detector remains opposite the emission port of the radiation source, and the carrying platform is located between the radiation source and the detector;
• wherein the detection apparatus further comprises:
• a controller, wherein the radiation source is electrically and/or communicatively connected to the controller, and the detector is electrically and/or communicatively connected to the controller;
• wherein the controller is configured to:
• control the radiation source and the detector to rotate around the rotation axis;
• control, when the radiation source rotates, the radiation source to emit radiation that passes through the to-be-tested battery on the carrying platform and that is projected onto the detector;
• acquire a detection image of the to-be-tested battery based on the radiation received by the detector;
• and
• determine deformation information of the to-be-tested battery based on the detection image;
• wherein the to-be-tested battery comprises a bottom surface, the bottom surface has a gluing region, and the controller is further configured to:
• position the carrying platform such that the rotation axis is located on the carrying surface of the carrying platform during rotation of the radiation source and the detector to control the bottom surface of the to-be-tested battery, said bottom surface being attached to the carrying surface of the carrying platform.
