Embodiment Construction

[0022] The circuit board counting device provided by the present invention uses sensors, amplifiers, counters and mechanical design structures to convert the presence or absence of targets into pulsed electrical signals for accurate counting, and converts the quantity change signals of tiny targets into The electric pulse signal that the counter can recognize, and the counter finally displays the final technical result in the form of LED through processing the input signal. The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0023] see figure 1 , a counting device for a circuit board, including a sensor fixed on a slide rail driven by a motor, the slide rail drives the sensor to reciprocate between the two ends of the target to be counted; the sensor checks the presence or absence of the target during the movement Detect, and input the detection res...

Abstract

The invention discloses a counting device for a circuit board. The counting device comprises a sensor fixed on a slide rail driven by a motor. The slide rail drives the sensor to reciprocate between two ends of a to-be-counted object. The sensor detects presence of the object during motion and outputs corresponding optical signals into an amplifier. The amplifier performs presence judgment to the object through a preset threshold and converts input optical signals into pulse signals. A counter counts the pulse signals transmitted by the amplifier accumulatively, and displays the counting result. The problem that manual counting is low in efficiency and poor in accuracy is solved, and highly accurate and efficient counting is achieved.

Description

technical field [0001] The invention belongs to the technical field of counters and relates to a counting device for circuit boards. Background technique [0002] At present, there is no counting device specially used for counting the number of integrated circuits in the industry. The current circuit packaging production line uses manual counting for each batch of circuits. This method is not only time-consuming (about 5 for each batch of circuits). —8 minutes) and due to the individual differences of operators and other reasons, there may be differences between the counted quantity and the actual quantity, so there will often be quality problems such as more materials and less materials, mixed batches, etc. Contents of the invention [0003] The problem solved by the present invention is to provide a counting device for circuit boards, which converts the presence or absence of objects into pulsed electrical signals for accurate counting, effectively solving the problems o...
