DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0033] In the production process of USB data cables, appearance testing is one of the important links to ensure product quality. However, there are still many problems in the appearance testing of USB data cables. On the one hand, the traditional appearance testing method mainly relies on manual inspection. The inspectors observe the appearance of the data cable with the naked eye to determine whether there are defects. This method is not only inefficient, but the test results are easily affected by subjective factors of the inspectors, such as fatigue and lack of concentration, resulting in a high rate of misjudgment. On the other hand, with the continuous advancement of science and technology, some automated appearance inspection equipment has gradually been applied to production. However, these devices have also exposed some shortcomings in actual use. For example, the detection accuracy of some equipment is limited, and it is difficult to accurately identify some subtle appearance defects; it is often impossible to achieve an efficient automated production process. In order to improve the production quality and efficiency of USB data cables and meet the market demand for high-quality data cables, a batch testing device for USB data cable production is provided to solve the existing defects. The specific operations are as follows:

[0034] Combination Figure 1-Figure 9 The present invention provides a batch testing device for USB data cable production, comprising a base 11, a top of the base 11 is embedded with a propulsion assembly 2, two groups of propulsion assemblies 2 are arranged on the left and right sides of the base 11, a detection assembly 3 is arranged in the middle of the base 11, a first group of propulsion assemblies 2 is arranged on the left side of the detection assembly 3, and a second group of propulsion assemblies 2 is arranged on the right side of the base 11;

[0035] The propulsion assembly 2 includes a first electric push rod 24, the output end of the first electric push rod 24 is connected to a side push bar 23, the end of the side push bar 23 is connected to a support frame 21, the outer surface of the support frame 21 is installed with a lower platform 15, the top of the lower platform 15 is connected to a clamping arm 16, the top of the clamping arm 16 is connected to an upper platform 12, the clamping arm 16 is used to connect the upper platform 12 and the lower platform 15 together, the top side of the upper platform 12 is connected to a connecting plate 14, the upper surface of the connecting plate 14 is installed with a CCD scanner 13, the base 11 and the lower platform 15 are connected through the first electric push rod 24, the side push bar 23 and the support frame 21, the lower platform 15 is arranged at the top of the base 11 and the two are kept in sliding connection;

[0036] The upper platform 12 and the lower platform 15 are both provided with a reserved groove 26, and a propulsion belt 22 is embedded in the reserved groove 26. The propulsion belt 22 is driven by a motor, and an inner nesting ring 25 is also provided on the propulsion belt 22. The inner nesting ring 25 is embedded with the line body 17 to be detected. The upper platform 12 and the lower platform 15 are both installed with the propulsion belt 22. The outer surface of the propulsion belt 22 is provided with a circular groove, and the inner nesting ring 25 is embedded in the circular groove. The circular grooves on the two groups of propulsion belts 22 correspond to each other. The circular grooves on the first group of propulsion belts 22 and the circular grooves on the second group of propulsion belts 22 are engaged to clamp the line body 17 to be detected therein;

[0037] The inner wall of the inner nesting ring 25 is provided with an anti-skid pad, and the inner nesting ring 25 is driven by a micro motor, and the micro motor drives the inner nesting ring 25 to rotate in the groove provided on the inner side of the propulsion belt 22;

[0038] In the batch inspection of the line body 17 to be inspected, the first thing to do is to integrate the line body 17 to be inspected, so that it is convenient to test its appearance after integration to ensure the integrity of the line body 17 to be inspected. When the motor drives the propulsion belt 22 to rotate, the data lines are put into the grooves on the propulsion belt 22 in sequence. When the grooves on the two groups of propulsion belts 22 approach each other during the transmission process until they correspond to each other, the line body 17 to be inspected is fixed by the propulsion belt 22. With the synchronous transmission of the propulsion belt 22, the line body 17 to be inspected is pushed outward in an orderly manner. As the line body 17 to be inspected is pushed through the bottom end of the CCD scanner 13, its appearance state is detected by the CCD scanner 13, thereby realizing the test of the line body 17 to be inspected. When the line body 17 to be inspected is tested by the CCD scanner 13, in order to improve the accuracy of the test, the following are provided:

[0039] Ensure that the CCD scanner 13 is correctly installed and connected to the control system, and can collect image data normally. An LED light group with adjustable ambient light is also provided and installed in a suitable position to ensure that the detection area of the to-be-detected line body 17 can be evenly illuminated. Finally, set the parameter combinations of different ambient lights in the control system so that they can be quickly switched when needed.

[0040] The operations are as follows:

[0041] S1: The CCD scanner 13 performs an appearance inspection on the to-be-detected line body 17. When it detects a possible appearance defect but is unable to determine, the CCD scanner 13 sends a signal to the control system.

[0042] S2: After receiving the signal, the control system immediately issues an instruction to stop the forward movement of the to-be-detected line body 17 to ensure that the to-be-detected line body 17 stays at the current detection position.

[0043] S3: According to the preset program, the control system sequentially switches different ambient light parameters. First, adjust the brightness from low to high, and then adjust the color temperature. After each ambient light switch, the CCD scanner 13 re-collects the image of the data line to obtain the appearance image of the data line under the new ambient light.

[0044] S4: The control system analyzes the images collected under different ambient lights. If the appearance defect still exists under any ambient light, then it is determined that the data line is a defective product; record the defect information, including the defect type and location, for subsequent quality analysis and improvement; if the appearance defect disappears after the ambient light switch, it is judged as normal appearance.

[0045] S5: When it is determined that the appearance of the data line is normal, the control system issues an instruction to let the data line continue to move forward and enter the next detection link or packaging link.

[0046] Where the image feature value collected is X, and the normal feature value range is [A, B]. The judgment logic is: If X B, there is a suspected appearance defect, and at this time, a signal is sent to the control system to stop the advancement of the data line.

[0047] When n kinds of ambient lights are switched, respectively judge whether there is an appearance defect under each ambient light, and use variables p1, p2,..., pn to represent. Among them, pi being true means that there is no appearance defect under the i-th ambient light, and being false means that there is.

[0048] The operation formula for judging a defective product: As long as there is an appearance defect under one of the ambient lights, that is, p1 or p2 or... or pn is true, then it is judged as a defective product.

[0049] The calculation formula for judging whether the appearance is normal is: Only when all pi are true, that is, p1 and p2 and ... and pn are true, can it be judged that the appearance is normal.

[0050] When the CCD scanner 13 is in the detection stage, the inner nested ring 25 in the groove of the propulsion belt 22 is driven by the motor to rotate. After the inner nested ring 25 rotates, the inner nested ring 25 engages with the wire body 17 to be detected, thereby driving the wire body 17 to be detected to twist. During the twisting process, the CCD scanner 13 is used to measure the condition of the surface of the wire body 17 to be detected, so as to determine whether there are cracks on the surface.

[0051] In the test of the line body 17 to be tested, in order to further improve the test and improve the test results, a detection component 3 is also provided, and the specific operation is as follows:

[0052] The base 11 is also provided with a detection assembly 3, which includes a detection platform 31, a cushion block 32 is connected to the top surface of the detection platform 31, a groove 33 is provided on the side of the cushion block 32, a sliding block 36 is embedded in the groove 33, a lever 34 is connected to one side of the sliding block 36, a second electric push rod 35 is connected to the end of the lever 34, grooves 33 are provided on both sides of the cushion block 32, the grooves 33 are arranged in a Z shape, the lever 34, the second electric push rod 35 and the sliding block 36 are provided in two groups, the lever 34, the second electric push rod 35 and the sliding block 36 are respectively arranged on the left and right sides of the cushion block 32, and the two groups of levers 34 are staggered and arranged on both sides of the cushion block 32, when one group of levers 34 slides to the highest point of the groove 33 through the sliding block 36, the sliding block 36 in the other group of levers 34 is located at the lowest point, one group of levers 34 is arranged on the left side of the line body 17 to be detected, and the other group of levers 34 is arranged on the right side of the line body 17 to be detected;

[0053] When testing, it is necessary to determine whether the connector and the wire on the wire body 17 to be tested are tightly connected. The side push bar 23 is pushed by the first electric push rod 24 arranged on the base 11, and the side push bar 23 is pushed to move outward. When the side push bar 23 moves, the position of the support frame 21 also moves. The movement of the support frame 21 drives the upper platform 12 and the lower platform 15 to move. When the clamp arm 16 is clamped on the connector of the wire body 17 to be tested, the support frame 21 moves outward so that the connector and the wire are pulled. Under a reasonable force, it is determined whether the connection between the two is firm. After the test connection is firm, the push of the second electric push rod 35 drives the lever 34 and the sliding block 36 inside the groove 33. During the sliding process, the sliding block 36 will move along the track of the groove 33. At this time, as the second electric push rod 35 pushes the lever 34 to rise, the second electric push rod 35 continues to push after rising, so that the lever 34 moves to one side of the wire body 17 to be detected, and then pushes the wire to make the wire body 17 to be detected taut, so as to be analyzed by the CCD scanner 13. After the first group of levers 34 pushes the wire to move in one direction to make it taut, the first group of levers 34 descends, and the second group of levers 34 pushes the wire to the opposite direction to make it taut. By stretching in different directions, the test of the wire body 17 to be detected is further strengthened, and the accuracy of the test of the wire body 17 to be detected is improved.
