Description

Technical Field

[0001] The present invention belongs to the technical field of power line production equipment, and in particular relates to a power line positioning method, a device, a power line production equipment and a storage medium. Background Art

[0002] The power plug cable is produced by going through various processes: for example, a certain length is cut according to needs, and then the outer insulation of the power cord is stripped to expose the inner core wire with inner insulation. Then, the inner insulation on the front section of each single-core wire is stripped to expose the metal wire, and then a corresponding terminal is installed on the metal wire of each single-core wire one by one. After the terminal is installed, it needs to be pressurized and crimped to make a cable for connecting electrical equipment to alternating current.

[0003] The power cord positioning is mostly done by visually identifying the color with the human eye, and then the power cord is manually positioned by hand, and then put into the next process for processing. The core wire of the power cord is mostly shaped manually, that is, the live wire, ground wire, and neutral wire are manually shaped separately, and then put into the mold to rivet the terminal. Manual positioning is mostly used in the alignment and riveting processing of the plug inner frame, that is, the live wire, ground wire, and neutral wire are manually inserted into the riveting holes of the plug inner frame, and then riveted. The manual connection of the power cord and the plug not only increases labor costs and low work efficiency, but also makes people easily fatigued, resulting in incorrect wiring sequence. Power cords with incorrect wiring sequence enter the market, which are easy to burn electrical appliances, causing huge economic losses and casualties. Summary of the invention

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] Figure 1 The following is a schematic diagram showing a flow chart of a method for locating a power line. Figure 1As shown, a power line positioning method provided by the present invention is used for power line production equipment, comprising the following steps:

[0048] S10, collecting an image of the power line, and selecting a range to be detected by selecting a rectangular frame;

[0049] The power cord production equipment of the present application includes an industrial camera and a strip light source arranged directly above the power cord to capture an image of the power cord so that the image is displayed clearly.

[0050] Among them, a rectangular frame is created to select the area to be detected, that is, the range to be detected, so as to narrow the detection range. The present invention can realize the judgment of the position of the wire core from the selected range to be detected.

[0051] S20, extracting the area where each core of the power line within the range to be detected is located;

[0052] Specifically, the color extraction module extracts the color of each wire core of the power line within the detection range, thereby distinguishing the areas where the live wire, the neutral wire and the ground wire of the power line are located.

[0053] S30, when the target core is blocked by the upper core, matching the target rotation parameter of the target core according to the blocking condition of the target core;

[0054] In this embodiment, after the area where each core is located is determined by the color extraction module, it can be judged whether the target core is blocked by the upper core. Specifically, the judgment is made as follows:

[0055] Determine whether three wire cores are detected within the to-be-detected range;

[0056] If three wire cores are detected within the detection range, it is determined whether the target wire core is located at the target position. If the target wire core is at the target position, the positioning is completed and the next process is entered; if the target appears not to be at the target position, it is determined that the target wire core is blocked.

[0057] By judging the shielding condition of the target wire core and the real-time position of the target wire core, it is determined whether the power cord needs to be rotated.

[0058] S40, controlling the target wire core to rotate to a target position with the target rotation parameter.

[0059] The power cord positioning provided by the embodiment of the present invention determines the target rotation parameters of the power cord by detecting whether the target wire core is blocked by the top wire core within the detection range, so that the target wire core can be quickly rotated to the target position, thereby improving production efficiency and greatly enhancing positioning accuracy.

[0060] In this embodiment, after completing the image acquisition of the power line, there are many situations, such as: the target line core is already at the target position; the upper layer line core includes two and completely blocks the target line core, etc. In order to distinguish the above situations, Figure 2 As shown, the method also includes:

[0061] If three wire cores are not detected within the to-be-detected range, the power line is controlled to rotate along a first direction by a preset first rotation angle, and the image of the power line is recaptured for positioning.

[0062] If only two colors of cores can be found through the script module, the script module sends a command to the controller, and the controller sends a rotation command to the motor that controls the rotation of the power cord. After the motor is turned on, the motor drives the power cord to rotate in a first direction by a preset first rotation angle, so that the three colors of cores are displayed in the image. For example, the power cord is controlled to rotate 15° in a counterclockwise direction, or the power cord is controlled to rotate so that it is located on the left side of the upper core after rotation.

[0063] In this embodiment, after extracting the area where each core of the power line within the to-be-detected range is located, the method further includes:

[0064] Noise is filtered out through particle analysis to make the boundaries of each core clearer.

[0065] The analysis module is used to eliminate noise interference, and then the script module is used to determine whether the three colors of wire cores can be detected, so that the detection efficiency is improved.

[0066] In this embodiment, the target rotation parameter of the target core includes a target rotation direction;

[0067] The step of matching the target rotation parameter of the target core according to the shielding condition of the target core includes:

[0068] When the target wire core is on the first side of the upper wire core, the target rotation direction is the first rotation direction;

[0069] When the target wire core is on the second side of the upper wire core, the target rotation direction is a second rotation direction, wherein the first rotation direction and the second rotation direction are opposite.

[0070] For example, when the target core is on the left side of the upper core, the target rotation direction is clockwise, and the target core can be quickly rotated to the target position by rotating the power cord clockwise; when the target core is on the right side of the upper core, the target rotation direction is counterclockwise, and the target core can be quickly rotated to the target position by rotating the power cord counterclockwise.

[0071] The target wire core in this application can be a neutral wire, a live wire or a ground wire, and the target position is the upper layer.

[0072] Further, the target rotation parameter of the target core includes a target rotation angle;

[0073] The step of matching the target rotation parameter of the target core according to the shielding condition of the target core includes:

[0074] Within the range to be detected, measuring the exposed width of the target wire core;

[0075] The target rotation angle of the target wire core that matches the exposed width of the target wire core is searched according to a preset corresponding relationship table.

[0076] The corresponding relationship table in this embodiment is prepared and configured in the controller when the controller leaves the factory. The corresponding relationship table is used to record the corresponding relationship between the exposed width of the target wire core and the target rotation angle of the target wire core.

[0077] The controller can be used to obtain the target rotation angle of the target core corresponding to the width according to the acquired exposed width of the target core and call the corresponding relationship table.

[0078] If three core wires can be found, extract the brightness channel image of the original color image, and use a caliper or other straight line finding tool to measure the exposed wire width of the target wire core. Finally, through the linear relationship between the exposed wire width and the target rotation angle, the angle that the motor needs to rotate is obtained, and the power cord is rotated to rotate the ground wire to the target position.

[0079] The power cord positioning method provided by the embodiment of the present invention detects the width of the exposed wire core after the target wire core is blocked by the top wire core, obtains the target rotation angle of the power cord by looking up the table, and determines the target rotation direction of the power cord according to the relative position relationship between the target wire core and the upper wire core, so that the target wire core can be quickly rotated to the target position, thereby improving production efficiency and greatly improving positioning accuracy.

[0080] In this embodiment, the positioning result and the detection image are saved by the data storage module for easy backtracking. The positioning result is fed back to the controller through the TCP communication protocol of the network communication module, and the controller controls the motor to rotate, so that the ground wire is facing upward.

[0081] For the method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should know that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously.
