The design combines mechanical structure and electronic sensing technology and is widely used in electronic component manufacturing, warehousing logistics and other fields.

[0003] The existing light-shielded photoelectric sensing counter in the diode counting device will block the infrared light emitted by the infrared light-emitting tube when the object passes through the counter, causing the light signal received by the photoelectric receiving tube to change. The photoelectric receiving tube converts this changing signal into an electrical signal, usually a voltage or current change. After amplification and processing, the electrical signal forms a counting pulse. The counting pulse is recorded and displayed by the counting logic circuit, thereby realizing the counting of the object.

[0004] Due to the different sizes of the objects to be counted in actual work, when the volume of the diode to be counted is small, the distance between the inductive switch of the counter and the diode is too large, and when the object to be counted is far away from the inductive switch of the counter, it may not be counted, thereby causing counting errors and reducing the accuracy of counting, and increasing the probability of false triggering and missing triggering of the counter.

[0029] The counter 2 is a light shielding photoelectric inductive counter, when the diodes pass through the counter 2 during operation, the infrared light emitted by the infrared light emitting tube is blocked, so that the light signal received by the photoelectric receiving tube changes.
