Description

Technical Field

[0001] The present application relates to the technical field of cable production testing, and more specifically, to a fully automatic testing device and method for cable coding adhesion. Background Art

[0002] During the production process of cables, key information such as voltage, current, model, code, batch, manufacturer, etc. is usually printed on the surface of the cable. Accurate identification of this information is crucial for the correct use of cables and can effectively avoid electrical failures caused by misuse. When maintaining or repairing electrical equipment, clear and complete character identification can help technicians quickly and accurately determine the type, specification and purpose of the cable, so as to make appropriate decisions and operations.

[0003] However, during the production, transportation and wiring of cables, friction between cables and between cables and other objects is inevitable. If the characters printed on the cables have insufficient adhesion, they are prone to fall off and wear during these circulation processes, leading to quality problems.

[0004] In order to avoid marking problems on cables leaving the factory due to poor adhesion of the coded characters, companies will first use the same inkjet to print on a section of cable before officially putting it into production, and then manually test the adhesion of the printed characters. Once it is found that the adhesion is not up to standard, the ink ratio will be adjusted, or the material of the cable sheath will be replaced. By conducting adhesion tests, companies can effectively improve the reliability of their products, enhance their brand image and user trust, and at the same time reduce various risks that may be caused by marking failure.

[0005] However, the current cable coding character adhesion test mainly relies on manual operation. This method not only has low testing efficiency, but also has low levels of automation and intelligence. It is also difficult to quantify the size of the adhesion, and it is difficult to meet the current cable manufacturers' needs for efficient and accurate testing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0044] Next, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described herein.

[0045] Embodiment 1:

[0046] The detailed structural design of the fully automatic test device for the adhesion of cable inkjet coding in the embodiments of the present application is as Figures 1 - 3 shown. It adopts an integrated design and is divided into upper and lower layers. The upper layer includes a touch display 1, a moving slider 6, a linear motor 7, sensors, a workbench 8, a linear guide 10, a cable guide groove 17, a cable clamping module, a detection component, a friction adjustment component, etc.

[0047] The touch display 1 is installed on the workbench 8 through a display bracket 24 for convenient operation and data viewing.

[0048] The cable clamping module includes a first clamping table 15 and a second clamping table 20, which are aligned with the notch of the cable guide groove 17 and are fixedly arranged side by side on the workbench 8; the cable guide groove 17 is used to place the cable 16 to be measured, and its guide groove is arc-shaped, jointly restricting the displacement of the cable with the clamping table to prevent the cable from rotating.

[0049] The detection component includes a line array camera 2, a line array light source 3, etc. The line array camera 2 and the line array light source 3 are respectively installed on the moving slider 6 through a camera mounting bracket 18 and a light source mounting bracket 4. The moving slider 6 is assembled on the linear guide 10 and can slide along the linear guide 10.

[0050] The linear motor 7 is installed on the linear guide 10 and is located on the side close to the first clamping table 15, driving the moving slider 6 to reciprocate on the linear guide 10; the sensors include a second sensor 5 and a first sensor 11, which are used to position the moving slider 6 and can adjust the sensor position according to the character length; among them, the second sensor 5 and the first sensor 11 are fixed to both sides of the workbench 8 through a sensor bracket 21 and are parallel to the linear guide 10.

[0051] The friction adjustment component includes a friction material, a counterweight sliding table 12, a counterweight block 13, a drip pipe 14, a friction component mounting bracket 19, a counterweight sliding table guide rail 23, etc. Here, a wool felt 9 is selected as the friction material. The wool felt 9 is placed in the guide groove at the lower part of the counterweight sliding table 12 and is inserted into the counterweight sliding table guide rail 23 together. The counterweight sliding table 12 contacts the counterweight sliding table guide rail 23 through a ball, and they are all installed on the friction component mounting bracket 19. The friction component mounting bracket 19 is then fixed to the moving slider 6. The drip pipe 14 is fixed to the counterweight sliding table 12 through a drip pipe fixing buckle 22, and the counterweight block 13 is installed on the counterweight sliding table 12 and is an equal-weight stainless steel block for increasing friction.

[0052] The lower layer of the device adopts a sealed design for installing processing and control components such as processors, control boards, and solenoid valves. Specifically, Figure 4 The shown electrical principle block diagram, combined with the lower-layer sealed design, clarifies the layout of the device control core as follows: The processor, control board, solenoid valve, etc. are installed inside the enclosed cabinet of the lower layer of the device. The processor is used to detect software operation and image processing; the control board is used for the peripheral expansion of the processor, such as signal acquisition and external control; the solenoid valve controls the on-off of water flow and is used to wet the friction head and flush the cable; the touch display 1 is used for human-machine interaction; the linear array light source 3 has high brightness and is less affected by the external environmental light source, and is used to irradiate the cable to highlight the cable character features; to reduce the influence of the external environment and improve the recognition accuracy, a linear array camera 2 is selected to adopt a line-by-line scanning imaging method to collect a continuous string of inkjet characters; the sensor is used to determine the position of the moving slider 6 driven by the linear motor 7, and the sensor position can be adjusted according to the character length; the alarm light is used for alarm reminders during test end and when characters are worn or fallen off.

[0053] Figure 5 The 3D schematic diagram of the device in the embodiment of the present application is shown. This figure intuitively shows the integrated layered structure of the device, and completely presents the upper and lower layered layout of the device and the spatial positions of each component from a three-dimensional perspective, avoiding the perspective limitations of the two-dimensional view.

[0054] Particularly, in this device, the process of cable inkjet adhesion detection is specifically as follows: When performing cable inkjet adhesion detection, first place the cable characters upward into the cable guide groove 17, clamp both ends with the first clamping table 15 and the second clamping table 20, and add the number of weight blocks 13 according to requirements. Then set relevant parameters (such as the number of friction times, friction speed, etc.) through the touch display 1, and then click start test. The system will automatically open the solenoid valve to intermittently control the water flow to wet the wool felt 9, and at the same time the sliding table will drive the camera, light source, and friction device to start running from left to right (the left side of the linear guide 10 is the starting point). After the first friction and scanning are completed, the system automatically generates an image to automatically recognize the characters, and takes the characters recognized for the first time as the template characters and displays them on the main interface. After that, the characters recognized in each subsequent friction and scanning are compared with the template characters. If the characters recognized after a certain movement do not match the characters recognized for the first time, or the number of movements reaches the set number of times, the test system stops the test, records the number of movements, and gives an alarm reminder.

[0055] It is worth mentioning that this device can not only be applied to the inkjet adhesion tests of various specifications of wires, cables, and optical cables, but also be used for the character adhesion tests of straight or rolled materials, and has certain application value and application space.

[0056] Embodiment 2:

[0057] Figure 6 The flowchart of the method according to the embodiments of the present application is illustrated. As Figure 6 shown, the specific implementation steps of the method include: after the system is powered on, perform initialization operations and wait for the input of detection signals; after receiving the detection signals, the system drives the linear motor 7 through pulse output, and at the same time turns on the linear array light source 3. The linear array camera 2 scans the cable inkjet characters in a manner synchronized with the motor pulse frequency. When the sensor feeds back the motor in-place signal, stop scanning and generate a complete inkjet image; perform denoising and binarization preprocessing operations on the generated inkjet image; locate the inkjet character area in the image through traditional vision technology and split the characters or character strings into independent units; call the AI model to recognize the split characters to obtain the recognition result. If this test is the first recognition, set the recognition result as the standard characters. If it is not the first recognition, further determine whether the preset scanning times are reached. If so, end the test and trigger an audible and visual alarm. If not, compare the currently recognized characters with the standard characters. If the current characters are incorrect, stop the test and alarm. If the current characters are correct, control the motor to reverse for the next scan; until the preset scanning times are reached or the character comparison is incorrect, stop the test and issue an alarm reminder.

[0058] In summary, this method uses a combination of machine vision technology, AI character recognition technology, and automatic control technology to quantitatively test the adhesion of cable inkjet. While reducing the dependence on manual labor and realizing the quantification of test indicators, it greatly improves the intelligence and automation level of the test.

[0059] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit of the technical solutions of the present invention.
