Description

Technical Field

[0001] The present invention relates to the technical field of product detection, and particularly to a quality detection device for mobile phone data cables. Background Art

[0002] As an indispensable electronic device accessory in our daily life, the data cable mainly undertakes the functions of charging and data transmission. The quality and performance of the data cable are directly related to the usage experience and safety of the device. Therefore, the detection standards for data cables are of great significance for ensuring user safety and product performance; The detection of data cables mainly includes: electrical safety, physical durability, environmental adaptability, material environmental protection, as well as compatibility and electromagnetic compatibility, etc. Since there are many types of data cable detections, a relatively wide range of equipment types are required. In actual applications, a device called a "data cable comprehensive detector" can achieve the detection of most of the above functions. Therefore, in the production of data cables, a data cable comprehensive detector is mostly used to detect the quality of data cables; The usage method of the data cable comprehensive detector is relatively simple, that is, first set the detection indicators of the instrument, and then manually insert both ends of the data cable into the detection holes of the instrument. After the data cable is powered on, the detection will be automatically completed, and the detection data will be displayed through the display screen; The above detection method requires a long and repetitive process. Since the diameter of the detection hole of the detector is small, and people will also have visual and hand muscle fatigue under long-term repetitive work, it is inevitable that there will be jams and mistakes during the process of inserting the data cable connector into the detection hole, which will affect the detection speed and reduce the efficiency of the quality detection of mobile phone data cables. Summary of the Invention

[0003] The purpose of the present invention is to propose a solution to solve the problem that it is easy to jam during the repeated plugging and unplugging operation of the data cable connector in traditional detection, resulting in low detection efficiency.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions: A quality detection device for mobile phone data cables includes a machine body and a detection component arranged on the surface of the machine body for detecting the quality of the data cable, and further includes a quick plugging and unplugging component arranged on the upper part of the machine body for improving the plugging and unplugging efficiency of the data cable connector: The quick plugging and unplugging component includes a driving shaft rotatably connected to the upper part of the machine body. A detection roller is fixedly connected to the outside of the driving shaft. Photoelectric sensors are arranged on both sides of the upper end of the machine body.

[0006] As a further description of the above technical solution: The pushing assembly includes a first chute opened on the front and rear inner side walls of the detection roller corresponding to the position of the quick plugging and unplugging assembly. The sliding seat is slidably connected to the inside of the first chute, and an electric push rod for pushing the sliding seat to horizontally displace is fixedly connected inside the first chute.

[0007] As a further description of the above technical solution: An unloading assembly is provided in the middle of the detection roller.

Driving wheels are rotatably connected to one end of the movable seat close to each other, and the circumferences of the driving wheels are in pressing contact with the circumference of the clamping block. A motor for driving the driving wheels to rotate is fixedly connected to one side of the movable seat.

[0010] As a further description of the above technical solution: The adjustment assembly further includes a pressure sensor arranged at the far end inside the sliding seat. The electric push rod penetrates into the inside of the sliding seat and is movably connected with the inner wall of the sliding seat by a third spring. The elastic force of the third spring is greater than the resistance suffered by the sliding seat when sliding inside the first chute.

Compared with manual plugging and unplugging, the error rate is greatly reduced. At the same time, inserting and unplugging flat also reduces the wear between the data cable connector and the detection jack and reduces the life loss of the detection jack.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0018] As Figures 1-8 shown, what the present invention provides: A mobile phone data cable quality detection device, including a body 10 and a detection component 20 arranged on the surface of the body 10 for detecting the quality of the data cable, and further including a quick plug - and - unplug component 30 arranged on the upper part of the body 10 for improving the plug - and - unplug efficiency of the data cable connector: The detection component 20 includes a display screen 22 and a control key 21 movably connected to the front end of the body 10. The front end of the body 10 is provided with a detection cavity 24, and both inner walls of the detection cavity 24 are provided with detection jacks 23. The quick plug - and - unplug component 30 is arranged inside the detection cavity 24; The quick plug - and - unplug component 30 includes a drive shaft 31 rotatably connected to the upper part of the body 10. The outside of the drive shaft 31 is fixedly connected with a detection roller 32. Photoelectric sensors 34 are arranged on both sides of the upper end of the body 10. A stepper motor 33 for driving the drive shaft 31 to rotate is arranged on one side of the body 10; The quick plug - and - unplug component 30 further includes a clamping component 35 disposed on both sides of the detection roller 32 for fixing the data - line connector and a pushing component 36 for pushing the data - line connector to complete the plugging operation. The clamping component 35 includes sliding seats 351 disposed on both sides of the detection roller 32. A movable seat 352 slidably penetrates through one end of the sliding seats 351 that are close to each other. A first spring 353 is fixedly connected between the movable seat 352 and the sliding seats 351. One end of the movable seat 352 that is close to each other is movably connected to a clamping block 354. Both the upper and lower ends of the clamping block 354 are rounded off. A clamping groove 355 is formed at one end of the clamping block 354 that is close to each other. The pushing component 36 includes first chutes 361 formed on the front and rear inner side walls of the detection roller 32 corresponding to the position of the quick plug - and - unplug component 30. The sliding seats 351 are slidably connected to the inside of the first chutes 361. An electric push rod 362 for pushing the sliding seats 351 to horizontally displace is fixedly connected inside the first chutes 361.

[0019] Specifically, first, the staff fixes the connectors at both ends of the data line through the clamping component 35. When fixing, since both the upper and lower ends of the clamping block 354 are rounded off, by pressing, the force can be applied to the clamping block 354 by using the arc - shaped edge of the rounded corner, so that the clamping blocks 354 move away from each other and push the movable seat 352 to slide along the surface of the sliding seats 351. In this process, the first spring 353 is compressed. Until the data - line connector is stuck into the clamping groove 355 and then the pressing on the data - line connector is released. At this time, the first spring 353 resets and pushes the clamping block 354 to clamp the connector of the data line by using the clamping groove 355. In addition, since photoelectric sensors 34 are provided on both sides of the upper end of the machine body 10, when fixing the data - line connector, the hands of the staff will block the photoelectric sensors 34, making the photoelectric sensors 34 on both sides in an open - circuit state. When the data - line connector is fixed, the blocking of the photoelectric sensors 34 is removed, and at this time the circuit is in a closed - circuit state. Therefore, the controller controls the stepping motor 33 to work. The stepping motor 33 drives the detection roller 32 to rotate clockwise by 180 degrees through the drive shaft 31, so that the data line originally located at the top of the detection roller 32 is displaced to the bottom of the detection roller 32. Then, under the control of the controller, the electric push rod 362 pushes the sliding seats 351 to slide along the inside of the first chutes 361, so that the connector of the data line is inserted into the detection jacks 23 on both sides of the detection cavity 24. At this time, by observing the data on the display screen 22, it can be known whether the detection result is qualified. It should be noted that the photoelectric sensors 34, the stepping motor 33, the electric push rod 362 and the controller are all prior arts, so the operating principles between them will not be elaborated here. Through the cooperation of the quick clamping assembly 35 and the pushing assembly 36, the data cable connector can be accurately inserted into the interior of the detection jack 23. Compared with manual plugging and unplugging, the error rate is greatly reduced. At the same time, the flat insertion and extraction also reduce the wear between the data cable connector and the detection jack 23, and reduce the life loss of the detection jack 23. Moreover, when a group of data cables are being detected, the other group of data cables are clamped and fixed, and the detection process is closely connected, further improving the detection efficiency.

[0020] As Figure 3 shown, in the middle of the detection roller 32, there is an unloading assembly 40. The unloading assembly 40 includes a storage groove 41 opened in the middle of the upper and lower end faces of the detection roller 32. At the notch of the storage groove 41, a cover plate 42 is hinged through a hinge 43, and a second spring 44 is fixedly connected between the cover plate 42 and the groove wall of the storage groove 41 in a linear array: Figure 4 The unloading assembly 40 further includes a force-receiving block 45 fixedly connected to the surface of the movable seat 352. In the middle of the rear end of the machine body 10, there is a material discharge port 47, and on both sides of the front end of the material discharge port 47, there are fixedly connected toggle rods 46.

[0021] Specifically, when fixing the data cable connector, since the length of the data cable is generally set between 1 and 1.5 meters, and the width of the machine body 10 is generally between 20 and 30 centimeters, the part between the two ends of the data cable will fall outside the detection roller 32. On the one hand, it affects the rotation of the detection roller 32, and on the other hand, the unstable swinging of the cable will also affect the detection data; Based on this, when clamping the data cable connector, the excess cable can be placed inside the storage groove 41. When placing it, just press the cover plate 42 towards the inside of the storage groove 41, so that the cover plate 42 rotates and folds along the hinge 43. At this time, the second spring 44 is compressed. Then, put the excess cable into the storage groove 41, and then release the pressure on the cover plate 42. Under the action of the reset of the second spring 44, the cover plate 42 is pushed to close the storage groove 41, so that the cable between the two ends of the connector will not cause interference during the rotation of the detection roller 32, and its own swinging amplitude is also relatively small, making the detection data more stable and reliable; In addition, when the detection roller 32 rotates 180 degrees, the original upper area rotates to the lower part. At this time, under the action of gravity, the cover plate 42 rotates and folds outwards from the storage groove 41 along the hinge 43, so that the excess cable falls from the inside of the storage groove 41. After the detection is completed, the detection roller 32 rotates again. During the rotation, the toggle rod 46 inside the detection cavity 24 will contact the force-receiving block 45 on the movable seat 352 and push the movable seat 352 to displace along the surface of the sliding seat 351, so that the clamping block 354 separates and releases the clamping of the data cable connector. Then, combined with the centrifugal force generated when the detection roller 32 rotates, the fixed data cable is discharged from the material discharge port 47, completing the unloading of the detected data cable.​

[0022] As shown Figures 3-6 in the figure, an adjustment assembly 50 is provided between the movable seat 352 and the clamping block 354. The adjustment assembly 50 includes second sliding grooves 51 opened on both sides of the clamping block 354, and a sliding rod 52 is slidably connected inside the second sliding grooves 51. The sliding rod 52 is fixedly connected to the inner side wall of the movable seat 352. Driving wheels 53 are rotatably connected to the closer ends of the movable seat 352, and the circumferences of the driving wheels 53 are in pressing contact with the circumference of the clamping block 354. A motor 54 for driving the driving wheels 53 to rotate is fixedly connected to one side of the movable seat 352: The adjustment assembly 50 further includes a pressure sensor 55 provided at the far ends of the inside of the sliding seat 351. The electric push rod 362 penetrates into the inside of the sliding seat 351 and is movably connected to the inner wall of the sliding seat 351 by a third spring 56. The elastic force of the third spring 56 is greater than the resistance suffered by the sliding seat 351 when sliding inside the first sliding groove 361.

[0023] Specifically, since the data cable connector has a front and a back side, if it is directly inserted without distinguishing during insertion, it will not only affect the detection efficiency, but also damage the data cable connector and the detection jack 23, thus affecting the reliability of the subsequent detection data; Based on this, when the fixed data cable rotates 180 degrees following the detection roller 32, during the process of the electric push rod 362 pushing the sliding seat 351 to slide, if the positions of the data cable connector and the detection jack 23 are opposite, the data cable connector cannot penetrate into its interior after contacting the detection jack 23. At this time, the electric push rod 362 continuously pushes the sliding seat 351. Since the sliding seat 351 cannot move due to the influence of the data cable connector, the telescopic end of the electric push rod 362 pushes the third spring 56 to contract until the telescopic end of the electric push rod 362 contacts the pressure sensor 55 and squeezes it. After that, the pressure sensor 55 transmits a signal to the controller, and the controller controls the motor 54 to work. The motor 54 drives the driving wheel 53 to rotate through its output shaft. Since the circumferences of the driving wheels 53 are in pressing contact with the circumference of the clamping block 354, the driving wheels 53 drive the clamping block 354 to rotate synchronously when rotating. When the clamping block 354 rotates, the sliding rod 52 slides inside the second sliding groove 51, so as to prevent the clamping block 354 from detaching from the clamping block 354 during the rotation process until the positions of the two clamping blocks 354 are replaced, completing the flipping of the data cable connector. After that, the electric push rod 362 pushes the sliding seat 351 to move again, so that the data cable connector is inserted into the detection jack 23 to complete the detection. By quickly adjusting the data cable connector, the influence on the detection speed caused by the insertion problem is further reduced; It should be noted that the pressure sensor 55, the electric push rod 362, the motor 54 and the controller are all prior arts, so the operating principles between them will not be elaborated here.

[0024] As Figure 7 withFigure 8 As shown, a pressing component 60 is provided inside the storage groove 41. The pressing component 60 includes storage cavities 61 that are arranged in a linear array and staggered in the detection roller 32. A rubber sheet 63 is slidably connected inside the storage cavity 61. One end of the rubber sheet 63 away from each other is fixedly connected with a movable rod 62, and one end of the movable rod 62 away from each other penetrates outside the storage cavity 61 and is fixedly connected with a counterweight block 64. Overflow holes are formed on the surface of the rubber sheet 63, and the overflow holes are frustum-shaped with a wider inner width and a narrower outer width. The storage cavity 61 is filled with non-Newtonian fluid: the gravity of the counterweight block 64 is greater than the resistance suffered by the movable rod 62 when it moves inside the storage cavity 61, and the aperture of the overflow hole of the rubber sheet 63 gradually decreases from one side to the other side.

[0025] Specifically, if there is an open circuit between the lines, but the disconnected lines happen to be overlapped during the detection, the open circuit cannot be detected at this time, thus affecting the accuracy of the detection result; Based on this, when the detection roller 32 is flipped 180 degrees, the detection operation starts. During the detection process, the movable rod 62 originally inside the storage cavity 61 will move from the center of the detection roller 32 to its circumference under the action of the gravity traction of the counterweight block 64. During the movement, the movable rod 62 will pull the rubber sheet 63 to move synchronously. Since the storage cavity 61 is filled with non-Newtonian fluid and the overflow holes on the surface of the rubber sheet 63 are frustum-shaped with a wider inner width and a narrower outer width, the non-Newtonian fluid cannot quickly pass through the narrow openings of the overflow holes when the rubber sheet 63 moves, so that the movable rod 62 can only move slowly, so that during the rotation of the detection roller 32, the movable rod 62 will not be affected by the centrifugal force and extend outside the storage cavity 61. At the same time, because the apertures of the overflow holes of the multiple rubber sheets 63 gradually decrease from one side to the other side, the speeds at which the multiple movable rods 62 extend outside the storage cavity 61 gradually decrease, so that the multiple counterweight blocks 64 press the data line in sequence. By pressing the data line, when the open circuit position happens to be overlapped together, it can be separated again, thus ensuring the rigor of the detection. In addition, by sequentially pressing in a peristaltic manner, the data line can be pressed in all directions, further improving the accuracy of the detection.

[0026] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
