The invention relates to the field of button
cell detection, in particular to a button
cell detecting and screening device. The button
cell detecting and screening device comprises a rack, a feeding mechanism, a
capacitance detecting mechanism, a pressure detecting mechanism, an optical detecting mechanism and a discharging mechanism, and the feeding mechanism, the
capacitance detecting mechanism, the pressure detecting mechanism, the optical detecting mechanism and the discharging mechanism are sequentially and annularly arranged on the rack. An annular conveying belt for conveying button cells is arranged on a
machine base. The
capacitance detecting mechanism comprises a
capacitance probe and a first push head. A
capacitance probe linear power source is vertically installed on a top frame and drives the
capacitance probe to move in the vertical direction, and the first push head is driven by a first push head linear power source to move in the direction perpendicular to the tangent line of the annular conveying belt. The capacitance detecting mechanism, the pressure detecting mechanism and the optical detecting mechanism are annularly integrated on one device, feeding, capacitance detection,
pressure detection, optical detection and discharging are carried out in sequence, the detection process is shortened, the occupied area is reduced, and the space
utilization rate is increased.
