Description

Technical Field

[0001] The present invention relates to the technical field of data line concentricity detection, and in particular to a data line concentricity detection device and a detection process. Background Art

[0002] During the factory inspection of data cables, it is generally necessary to inspect the appearance of the wire harness and the concentricity of the wire core inside the wire. Among them, the concentricity inspection of the wire core inside the wire is more troublesome. It is often necessary to cut a certain length of wire and then conduct sampling inspection. Not only is the inspection time-consuming, but it also consumes a certain amount of wire, wastes resources, and has high inspection costs.

[0003] At present, most companies use sampling to conduct testing, extract a certain amount of samples, cut them off, and then observe and measure the concentricity of all data cables. That is to say, conventional sampling testing can only be carried out after the cables are processed or produced, and online testing cannot be completed. This will not only affect the continuity of cable production and reduce production efficiency, but also lead to the scrapping of a large number of data cables when defective products are found in sampling testing, resulting in a waste of raw materials and resources. At the same time, although sampling testing can reflect the concentricity of the entire cable to a certain extent, the data cable still needs to be packaged after production, and packaging may also have a certain impact on the concentricity of the data cable. Therefore, it cannot be guaranteed that the concentricity of the data cable meets the standard after packaging. Summary of the invention

Of course, they are only examples, and the purpose is not to limit the present invention.

[0037] like Figure 1-6 As shown, this embodiment provides a data line concentricity detection device, including a bottom plate 1 and a data line 2. The upper end surface of the bottom plate 1 is sequentially provided with an ultrasonic probe 6, a positioning assembly 3 and a limiting roller 4 along the axial direction. The ultrasonic probe 6, the positioning assembly 3 and the limiting roller 4 each have two groups, and are symmetrically arranged along the axial center line of the bottom plate 1. The data line 2 passes through the positioning assembly 3, the limiting roller 4, the tension sensor 5, the limiting roller 4 and the positioning assembly 3 in sequence and then twisted 180°;

[0038] The tension sensor 5 and the ultrasonic probe 6 are externally connected to a computer, which is used to control the transmission of the data cable 2 and display and analyze the images collected by the ultrasonic probe 6. A winding machine is provided at the outlet end of the data cable 2, which is used to wind up the data cable 2.

[0039] Specifically, the two ultrasonic probes 6 can detect the information of the data cable 2 and feed the information back to the computer. Since the position of the data cable is twisted 180° when passing through the two sets of ultrasonic probes 6, the environment of the data cable after use is simulated, thereby ensuring that the detection results of the second set of ultrasonic probes 6 are close to the data from the time the data cable is packaged and wound until shipment (or after the data cable has been used for a period of time).

[0040] Furthermore, the positioning assembly 3 includes a positioning wheel 31, and the positioning wheel 31 is externally rotatably connected to the extrusion assembly 33. A locker 32 is installed outside the positioning wheel 31, and the locker 32 is used to limit the rotation of the extrusion assembly 33. The locker 32 includes a pressure plate 321, and the lower end surface of the pressure plate 321 is symmetrically fixedly connected with two sets of sliding connecting rods 322.

[0041] Furthermore, the positioning wheel 31 includes a positioning wheel body 311, a mounting groove 312 is provided on the outside of the positioning wheel body 311, a through hole is provided on the front end surface of the positioning wheel body 311, an elastic pad 315 is provided on the inner wall of the through hole, and three groups of sliding connection grooves 314 are spaced apart from each other in the positioning wheel body 311, and an extrusion plate 313 is slidably connected inside the sliding connection groove 314.

[0042] Furthermore, the extrusion assembly 33 includes a rotating ring 331 , an elastic ring 332 is formed outside the rotating ring 331 , and an extrusion groove 333 is formed on the front end surface of the rotating ring 331 .

[0043] Furthermore, a handle is provided on the outside of the extrusion assembly 33 , and one side of the extrusion plate 313 is in contact with the inner wall of the extrusion groove 333 .

[0044] Specifically, after the data line passes through the positioning assembly 3, the extrusion assembly 33 is rotated by turning the handle, and the inner wall of the extrusion groove 333 will squeeze the extrusion plate 313, so that the three groups of extrusion plates 313 squeeze the elastic pad 315 to complete the locking of the data line.

[0045] It should be noted that a positioning groove is provided inside the positioning wheel 31, and the sliding connecting rod 322 is slidably connected inside the positioning groove. A sliding connecting plate is fixedly connected to the bottom of the sliding connecting rod 322, and the size of the sliding connecting plate is adapted to the positioning groove. A spring is provided on the upper part of the sliding connecting plate, and the end of the spring facing away from the sliding connecting plate is fixedly connected to the inner wall of the positioning groove.

[0046] It is understandable that a protrusion is provided at the bottom of the pressing plate 321 , and the protrusion is used to squeeze the elastic ring 332 .

[0047] Furthermore, two groups of ultrasonic probes 6 are used to detect both sides of the data line 2 , and the data line 2 between the two groups of ultrasonic probes 6 has a fixed length.

[0048] Furthermore, the tension sensor 5 is used to wind the data cable 2 and send the tension data of the data cable 2 to the computer, so that the data cable 2 is transmitted with a preset tension through the computer.

[0049] Specifically, a preset tension can ensure that the data cable itself will not be overly tight or loose during the transmission process, thereby avoiding the twisting of the data cable during the transmission process.

[0050] It can be understood that the 180° twisting of the data line is mainly concentrated between the two groups of limit rollers 4 and the tension sensor 5. After the data line is twisted 180° in the conveying direction, the two groups of positioning components 3 will squeeze the data line, so that the data line is twisted 180° between the two groups of positioning components 3. That is, after the data line passes through the first group of positioning components 3, the twisted data line in the front will drive the data line that has just passed through the first group of positioning components 3 to twist, and the data line passing through the second group of positioning components 3 will be squeezed by the extrusion plate 313, and maintained in a state of being twisted 180° with the feed end while being conveyed.

[0051] Wherein, the positioning component 3 has a certain length.

[0052] Specifically, the data monitored by the ultrasonic probe 6 can form different waveform image models in the computer, and the waveform images obtained based on the data line detection whose concentricity is within the standard range can be compared to complete the online detection of the concentricity of the data line. There is no need to cut the data line, which effectively improves the convenience of detection and ensures the integrity of the wire.

[0053] The present invention also provides a method for detecting the concentricity of a data line, which is used to detect the concentricity of a data line, and comprises the following steps:

[0054] S1: Transmit the data line at a preset speed and tension;

[0055] S2: Detecting data lines through the first set of ultrasonic probes 6 and sending the detected data to the computer;

[0056] S3: Pass the data cable 2 through the first group of positioning components 3, and rotate the locker 32 through the handle to squeeze the extrusion plate 313 through the inner wall of the extrusion groove 333, so that the outside of the data cable 2 is squeezed and positioned, and then the data cable is sequentially wound around the limit roller 4, the tension sensor 5 and the limit roller 4 while twisting 180°, and finally the data cable 2 is passed through the second group of positioning components 3. The two groups of positioning components 3 complete the positioning of the data cable 2 during transmission;

[0057] S4: Processing the first received detection data by a computer to obtain a first waveform image, comparing the first waveform image with the standard waveform image, and if the deviation is greater than a first threshold, an alarm is issued and transmission to the data line 2 is stopped, and a mark is made on the data line 2;

[0058] S5: Detecting the data line through the second group of ultrasonic probes 6, and sending the detection data to the computer, wherein the first group of ultrasonic probes 6 and the second group of ultrasonic probes 6 detect two sides of the axial direction of the data line respectively;

[0059] S6: Processing the second received detection data by a computer to obtain a second waveform image, and comparing the second waveform image with the first waveform image and the standard waveform respectively; if the deviation between the second waveform image and the first waveform image is greater than the second threshold or the deviation between the second waveform image and the standard waveform image is greater than the first threshold, an alarm is issued, transmission to data line 2 is stopped, and a mark is made on data line 2.

[0060] like Figure 7 As shown, the data line that has just been produced can be led to the detection device. If an alarm occurs during the detection process, it can be marked and the production parameters can be adjusted in time to effectively improve the production yield.

[0061] It is understandable that when comparing the first waveform image with the standard waveform image, if the deviation is greater than the first threshold, it means that the concentricity is unqualified. At the same time, the second waveform image is obtained by twisting and squeezing the data line and then testing it, so the wire harness inside the data may have a slight offset, which may be positive or negative. Figure 8 It can be seen that if the deviation between the second waveform and the first waveform is greater than the second threshold, it means that the data line stability is not high and therefore unqualified. If the deviation between the second waveform and the standard waveform is greater than the first threshold, it means that the concentricity deviation of the data line will be too large after use.

[0062] Furthermore, the preset speed is specifically 8-15 cm / s, the preset tension is specifically 20N-25N, and the data line with qualified concentricity of the standard waveform is detected by an ultrasonic probe and then analyzed and processed by a computer to obtain the waveform.

[0063] Specifically, the data line is moved at a preset tension, thereby ensuring that the data line can be twisted 180° after passing through the positioning component 3, the limit roller 4 and the tension sensor 5 during the movement.

[0064] In summary, the data line concentricity detection device and detection process disclosed in the present application are provided with a positioning component 3, a limit roller 4 and a tension sensor 5, wherein the extrusion component 33 is rotated by turning the handle, so that the inner wall of the extrusion groove 333 will squeeze the extrusion plate 313, so that the three groups of extrusion plates 313 squeeze the elastic pad 315 to complete the locking of the data line, and at the same time, after the data line passes through the first group of positioning components 3, the data line twisted at the front will drive the data line that has just passed through the first group of positioning components 3 to twist, and the data line passing through the second group of positioning components 3 will be squeezed by the extrusion plate 313, and maintained in a state of 180° twisted with the feed end to be transported, so that when the data line is detected, the initial state and the twisted state of the data line can be detected at the same time, and the two groups of ultrasonic probes 6 will detect the information of the data line 2 and feed the information back to the computer, and by comparing the first waveform image, the second waveform image and the standard waveform, it can be accurately judged whether the concentricity of the data line is qualified, and whether the concentricity will be too large after its own use, and the comparison process does not need to cut the data line, which effectively improves the convenience of detection and ensures the integrity of the wire.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
