Problems solved by technology

The working environment of photovoltaic modules is relatively harsh, and the maximum temperature can reach 90-120 degrees Celsius. Generally, the tolerance range of the outer diameter of the cable is ±0.3mm, but the deviation of the outer diameter of the cable directly affects the installation of the cable and the sealing of the cable and the connector. When the diameter is large, the cable and connector cannot be installed. When the outer diameter of the cable is small, a hole will be formed between the cable and the connector at low temperature, resulting in water ingress, which directly affects the power generation efficiency of the photovoltaic module.
The existing technology uses manual detection of the outer diameter of the cable, and a set of data is detected every 5-10 minutes, about 5-10 data, while the cable production speed is generally 200m / min, and only 5-10 data are tested for 1000 meters , the outer diameter of the cable cannot be controlled in real time

Embodiment 1

[0019] Such as figure 1 As shown, an online SPC detection and data acquisition method for the outer diameter of the cable, the location of the data acquisition of the outer diameter of the tested cable is at the back of the cooling water tank, and the outer surface of the tested cable is dry, and the laser beam emitted by the semiconductor laser (1) is irradiated to the The octagonal prism (3) drives the octagonal prism (3) to rotate through the motor (2), and the laser beam reflected by the octagonal prism (3) is scanned and converted into parallel light through the prism (4) and passes through the test area (5). When the test area ( 5) When the cable under test passes through, it will block part of the parallel light and convert it into a low-level electrical signal on the photoelectric receiving tube (7) through the focusing prism (6), but there is no parallel light blocked by the cable under test It is then converted into a high-level electrical signal, and by calculating ...

Embodiment 2

[0022] A method for on-line SPC detection and data acquisition of the outer diameter of a cable. The data acquisition position of the outer diameter of the tested cable is at the rear side of a cooling water tank, and the outer surface of the tested cable is dry, and a laser beam emitted by a semiconductor laser (1) is irradiated to an octagonal mirror ( 3), the motor (2) drives the octagonal prism (3) to rotate, and the laser beam reflected by the octagonal prism (3) scans and passes through the prism (4) into parallel light and passes through the test area (5). When the test area (5) has When the cable under test passes through, it will block part of the parallel light and convert it into a low-level electrical signal on the photoelectric receiving tube (7) through the focusing prism (6), while the parallel light not blocked by the cable under test will be converted into High-level electrical signal, by calculating the scanning time of the low-level signal, calculate the oute...

Abstract

The invention discloses an online outside-diameter SPC detecting and data acquiring method for cables. The online outside-diameter SPC detecting and data acquiring method includes that a semiconductor laser emits laser beams to irradiate an octagonal prism, a motor drives the octagonal prism to rotate, and the laser beams reflected by the octagonal prism scan to pass the prism and are converted into parallel light passing a test area; when a cable to be tested passes the test area, part of parallel light is shaded, outer diameter of the cable to be tested in the scanning direction of the laser beams is calculated and transmitted to a computer through a communication line and is displayed on a screen in real time, a deviation relation of test values and standard values is displayed in real time via a curve chart, and data of the measured outer diameter are stored in the computer. By the online outside-diameter SPC detecting and data acquiring method, actual outer diameter of the cable on a cable production line is acquired in real time, and data of the outer diameter of the cable are stored, and traction speed or extrusion speed is controlled in real time, so that the outer diameter of cable production is controlled in real time.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an online SPC detection and data collection method for the outer diameter of a cable. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. The solar cells are packaged and protected after being connected in series to form a large-area solar cell module, and then cooperate with power controllers and other components to form a photovoltaic power generation device. [0003] Among many photovoltaic modules, photovoltaic cables and connectors are the key to connecting solar cells in series. The MC4 connector is a commonly used connector for photovoltaic modules. There is a rubber ring at the connection with the cable, which can prevent oil and water after connecting with the cable. The working environment of photovoltaic modules is rel...
