Description

Technical Field

[0001] This utility model relates to the field of photoconductors, and specifically to a photosensitive drum counting device. Background Technology

[0002] A photosensitive drum, also known as an OPC drum, is a photoelectric conversion device formed by coating the surface of a conductive aluminum tube with OPC material (organic photoconductor material). After production, photosensitive drums need to be packaged. A certain number of photosensitive drums are packed into boxes, and the quantity in the boxes needs to be checked to avoid shortages or over-packing. Currently, the drums are usually counted manually during packing, and then weighed before sealing. However, because the error range of weighing cannot accurately reflect the difference in quantity, shortages or over-packing still occur. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a photosensitive drum counting device, comprising: a flat metal detector, a packaging box containing multiple vertically placed photosensitive drums (each photosensitive drum has a copper electrode at its top), a column located on one side of the flat metal detector, and a main control device located at the top of the column and electrically connected to the flat metal detector.

[0004] The flat-panel metal detector is used to sense the copper electrode at the top of each photosensitive drum in the packaging box and output a sensed voltage corresponding to the number of copper electrodes.

[0005] The main control device receives the induced voltage output by the flat-panel metal detector and calculates the number of copper electrode sheets based on the induced voltage, thereby determining the number of photosensitive drums in the packaging box (the number of photosensitive drums is equal to the number of copper electrode sheets).

[0006] Preferably, the main control device is also equipped with a display, and the main control device controls the display to show the number of photosensitive drums in the packaging box.

[0007] Preferably, the main control device is also equipped with an alarm, and the main control device also determines whether the calculated number of copper electrode sheets is qualified, and controls the alarm to sound when it determines that the number of copper electrode sheets is unqualified (too few or too many copper electrode sheets, i.e., too few or too many photosensitive drum sheets are installed).

[0008] Preferably, the alarm is an audible and visual alarm.

[0009] Preferably, the top surface of the flat metal detector is provided with a frame line for marking the area where the packaging box is placed; the packaging box is placed within the frame line.

[0010] The advantages and beneficial effects of this utility model are as follows: It provides a photosensitive drum counting device that can automatically count the number of photosensitive drums in a single packaging box and can issue an alarm when there are fewer or more photosensitive drums in the packaging box, thus avoiding the situation of fewer or more photosensitive drums in the packaging box. It can solve the problem of inaccurate quantity of products per box caused by manual counting and weighing differences, reduce the intensity of manual labor, and improve the automation level of the production line.
