Description

Technical Field

[0001] The present invention relates to the field of charger testing equipment, and particularly to a fully automatic mobile phone charger plug obliquely inserted testing instrument. Background Art

[0002] After the commonly used mobile phone chargers are produced, a series of detection tests are required to ensure the quality and durability of the products. Among them, spot-check plugging and unplugging tests are carried out on the chargers to test the influence on the connection stability between the data cable connector and the charger interface after multiple pluggings and unplugging of the data cable and the charger.

[0003] The prior art includes a driving structure and a movable part. The movable part fixes the joint of the data cable, and the driving structure drives the movable part to move towards or away from the charger interface, and so on repeatedly to achieve multiple plugging and unplugging tests. For example, in the prior art (Publication No.: CN206248258U, Publication Date: June 13, 2017), a charger head USB interface plugging and unplugging force testing device is disclosed. When performing the plugging and unplugging test, the lower clamping part is aligned with the upper clamping part, thereby realizing the plugging and unplugging force test of the charger head USB interface.

[0004] During the plugging and unplugging process, the data cable is always in a state of being parallel and aligned with the charger interface. However, in the actual use process, the direction of plugging and unplugging the data cable often forms a certain angle with the direction of the socket. Therefore, the existing plugging and unplugging test method does not conform to the actual plugging and unplugging method, and the test result is not objective enough. For this reason, in the prior art (Publication No.: CN220154564U, Publication Date: December 8, 2023), a charger plugging and unplugging test device is also disclosed. Its adjusting mechanism is arranged on the fixed frame, used to fix the data cable and adjust the orientation of the joint of the data cable. The adjusting mechanism is set to adjust the orientation of the data cable joint to simulate the situation where the direction of plugging and unplugging the data cable forms a certain angle with the direction of the socket in real life.

[0005] However, the adjusting mechanism in the above solution can only adjust the unilateral direction of the data cable. In the normal use process of the charger, the plugging and unplugging of the data cable are often irregularly obliquely inserted. Therefore, it is very difficult for the above solution to accurately imitate the randomness in the actual use process. In addition, the charger is not powered on during the plugging and unplugging test, so it is impossible to know whether there is a poor contact situation. Moreover, the charger is also prone to displacement during the plugging and unplugging test, and specific fixtures need to be equipped for clamping, resulting in inaccurate test results.

[0023] Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention.

[0024] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. 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 an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0027] As Figures 1-7 shown, a fully automatic mobile phone charger plug obliquely inserted test instrument of the present invention includes a machine platform 1, and a gantry bracket 2 is fixedly installed on the machine platform 1; An X-axis pusher 3 is fixedly installed on the front side of the gantry bracket 2. A Z-axis pusher 4 is driven and connected to the X-axis pusher 3. A jaw cylinder 5 is installed on the Z-axis pusher 4. Two wire clips 6 that approach and clamp each other are driven and connected to the jaw cylinder 5; A positioning platform 7 is fixedly installed on the machine platform 1. A Y-axis pusher 8 is fixedly installed on the positioning platform 7. A slide 9 is driven and connected to the Y-axis pusher 8. A socket 10 is fixedly installed on the slide 9. The socket 10 is arranged below the wire clips 6; A buffer mechanism 11 is arranged inside the positioning platform 7. The upper end of the buffer mechanism 11 is fixedly installed with a U-shaped bracket 12. A U-shaped slot 13 is formed on the U-shaped bracket 12. The socket 10 is arranged in the U-shaped slot 13 with a clearance fit; The principle is as follows: First, insert the charger plug 23 into the socket 10 of the slide 9, and then use the U-shaped bracket 12 to provide positioning for the charger plug 23. During the plugging and unplugging test, the charger plug 23 will not shift, ensuring the stability of the plugging and unplugging test, and effectively avoiding damage to the charger plug 23 during the plugging and unplugging test; in addition, the X-axis pusher 3 is set to push the Z-axis pusher 4 to move left and right, realizing the random left and right inclination during the plugging and unplugging of the data cable 24. Then, the Y-axis pusher 8 is used to drive the slide 9 to move back and forth on the positioning platform 7, realizing the random front and back inclination during the plugging and unplugging of the data cable 24. The left and right inclination and the front and back inclination of the data cable 24 are used to simulate the effect of plugging and unplugging the charger in real life. Finally, the Z-axis pusher 4 is used to drive the jaw cylinder 5 to move up and down, thereby realizing the automatic plugging and unplugging action during random inclination to test the plugging and unplugging reliability of the charger plug 23; at the same time, the socket 10 can be powered on so that the data cable 24 can be powered on when inserted into the charger plug 23, thereby realizing the counting of the effective number of plugging and unplugging.

[0028] Further: A universal joint 14 is fixedly installed between the Z-axis pusher 4 and the jaw cylinder 5. A limiting cylinder 15 is sleeved outside the universal joint 14 at intervals, and the limiting cylinder 15 is fixedly installed on the Z-axis pusher 4. The universal joint 14 can be used to realize the random inclination of the wire clamp 6. At the same time, the setting of the limiting cylinder 15 can limit the inclination angle of the wire clamp 6 and avoid the phenomenon of abnormal insertion and extraction caused by excessive inclination.

[0029] Further: An elastic member 151 is arranged between the limiting cylinder 15 and the universal joint 14. The elastic member 151 is made of silica gel material. This elastic stress can simulate the phenomenon of normal insertion and extraction of chargers in real life, thereby ensuring the reliability and accuracy of the insertion and extraction test.

[0030] Further: The X-axis pusher 3 includes a first cam 31, a first tension spring 32, a first motor 33, an X-axis slider 34, and an X-axis guide rail 35. The X-axis guide rail 35 is arranged horizontally and fixedly installed on the front side of the gantry bracket 2. The X-axis slider 34 is slidably fitted left and right on the X-axis guide rail 35. A right-angle bracket 16 is formed on the rear side of the X-axis slider 34. The right-angle bracket 16 is located above the gantry bracket 2. The first motor 33 is fixedly installed on the gantry bracket 2. The first cam 31 is rotatably fitted on the gantry bracket 2, and the first motor 33 drives the first cam 31 to rotate. The first tension spring 32 is fixedly installed between the upper side of the gantry bracket 2 and the right-angle bracket 16, and the first tension spring 32 drives the right-angle bracket 16 to always abut against the first cam 31. The principle of the X-axis pusher 3 is to use the first motor 33 to drive the first cam 31 to rotate, and the first tension spring 32 drives the right-angle bracket 16 to always abut against the first cam 31. Therefore, when the first cam 31 rotates, it can drive the X-axis slider 34 to move left and right on the X-axis guide rail 35, achieving the effect of random left and right inclination of the data cable 24.

[0031] Further: The Z-axis pusher 4 includes a second cam 41, a second tension spring 42, a second motor 43, a Z-axis slider 44, a Z-axis guide rail 45, and a lifting plate 46. The Z-axis slider 44 is fixedly installed on the front side of the X-axis slider 34. The Z-axis guide rail 45 is slidably fitted up and down in the Z-axis slider 44. The lifting plate 46 is fixedly installed on the front side of the Z-axis guide rail 45, and the lifting plate 46 and the Z-axis slider 44 are arranged at intervals in the front and rear directions. The second motor 43 is fixedly installed on the X-axis slider 34. The second cam 41 is rotatably fitted on the X-axis slider 34, and the second motor 43 drives the second cam 41 to rotate. A transverse frame 17 is formed on the side of the lifting plate 46. The two ends of the second tension spring 42 are respectively fixedly installed between the transverse frame 17 and the X-axis slider 34, and the second tension spring 42 drives the transverse frame 17 to always abut against the second cam 41. The working principle of the Z-axis pusher 4 is that the second motor 43 drives the second cam 41 to rotate. At the same time, the second tension spring 42 drives the transverse frame 17 to always abut against the second cam 41. The Z-axis guide rail 45 and the Z-axis slider 44 slide up and down relative to each other, thereby driving the lifting plate 46 to perform a stable lifting action. When the lifting plate 46 moves up and down, the wire clamp 6 at the bottom can be close to or away from the socket 10. When the wire clamp 6 clamps the data cable 24 and inserts the charger plug 23 into the socket 10, the data cable 24 can be automatically plugged and unplugged on the charger plug 23 to achieve the plugging and unplugging test.

[0032] Furthermore: The Y-axis pusher 8 includes a Y-axis slider 81, a Y-axis guide rail 82, a side plate 83, a third motor 84, a third cam 85, and a third tension spring 86. The Y-axis slider 81 is fixedly installed on the positioning platform 7, the Y-axis guide rail 82 is fixedly installed on the bottom side of the sliding table 9, and the Y-axis guide rail 82 is slidably installed in the Y-axis slider 81. The third cam 85 is rotatably installed on the sliding table 9, the third motor 84 is fixedly installed on the sliding table 9, and the third motor 84 drives the third cam 85 to rotate. The side plate 83 is vertically and fixedly installed on the rear side of the Y-axis guide rail 82. A right-angle frame 18 is formed on the front side of the sliding table 9. The two ends of the third tension spring 86 are respectively fixedly installed on the front end of the bottom side of the sliding table 9 and the right-angle frame 18, and the third tension spring 86 drives the side plate 83 to always abut against the third cam 85. The working principle of the Y-axis pusher 8 is that the third motor 84 drives the third cam 85 to rotate. At the same time, the third tension spring 86 drives the side plate 83 to always abut against the third cam 85, thereby effectively driving the Y-axis guide rail 82 to move back and forth on the Y-axis slider 81, effectively driving the sliding table 9 to move back and forth, achieving the effect of randomly moving the socket 10 back and forth, and further increasing the stress during the plugging and unplugging of the data cable 24. Cooperating with the X-axis pusher 3 to drive the data cable 24 to tilt left and right, the effect of randomly plugging and unplugging the data cable 24 at an angle on the charger plug 23 is achieved.

[0033] Furthermore: The operating speeds of the first motor 33, the second motor 43, and the third motor 84 are different from each other. By using three motors with different operating speeds, it is avoided that the inclination angles are the same every time due to the same speed, increasing the randomness of the inclined plugging and unplugging, being able to better simulate the plugging and unplugging actions in actual use, and making the test results more accurate.

[0034] Furthermore, a support base 19 is fixedly installed on the U-shaped bracket 12. A tapered slot 20 is formed in the support base 19. The socket 10 is arranged at the bottom side within the tapered slot 20. A silica gel part 21 is installed in the tapered slot 20 with a clearance fit. When the wire clamp 6 descends, it is arranged to press the silica gel part 21 within the tapered slot 20. When the wire clamp 6 presses down, it can simultaneously press the silica gel part 21, and the silica gel part 21 utilizes the tapered slot 20 to press the charger plug 23 installed inside, ensuring the firmness of the charger plug 23 during the plugging and unplugging tests, effectively avoiding the situation that the charger plug 23 is displaced due to the plugging and unplugging tests, and also avoiding the phenomenon that the socket 10 is damaged due to the charger plug 23 being plugged and unplugged in the socket 10 multiple times.

[0035] Furthermore, a square slot 22 is formed in the silica gel part 21. A charger plug 23 is installed in the square slot 22 with a clearance fit. The bottom end of the charger plug 23 is inserted into the socket 10 to complete the electrical connection. A data cable 24 is clamped and installed on the wire clamp 6. A USB female socket 25 is arranged at the upper end of the charger plug 23. When the wire clamp 6 descends, the lower end of the data cable 24 is inserted into the USB female socket 25 with a clearance fit to complete the electrical connection. At the same time, the wire clamp 6 presses the silica gel part 21, and the square slot 22 within the silica gel part 21 presses the charger plug 23 to complete the locking. The effect of automatic plugging and unplugging and power-on is achieved. At the same time, when plugging and unplugging, the square slot 22 can be made to contract inward by pressing the silica gel part 21 with the wire clamp 6, achieving the effect of stably clamping the charger plug 23 and avoiding the phenomenon of displacement during the plugging and unplugging process.

[0036] Furthermore, a power supply 26 is electrically connected and installed in the socket 10. The charger plug 23 is electrically connected to the power supply 26 through the socket 10. The lower end of the data cable 24 is inserted into the USB female socket 25 of the charger plug 23 to complete the electrical connection. The other end of the data cable 24 is electrically connected and installed with a first counter 27. When the data cable 24 is powered on, the first counter 27 can be used for counting, thereby recording the number of effective connections of the charger plug 23.

[0037] Furthermore, the first counter 27 performs plugging and unplugging counting each time it is powered on. A second counter 28 is arranged on the Z-axis pusher 4. The second counter 28 performs counting each time it moves downward. Finally, the value of the first counter 27 is compared with the value of the second counter 28 to obtain the plugging and unplugging reliability of the charger plug 23.

[0038] A pressing frame 61 is fixedly installed on the lower side of the wire clamp 6. The wire clamp 6 presses the silica gel part 21 through the pressing frame 61. The wire clamp 6 can more stably press the silica gel part 21, and the silica gel part 21 is deformed to lock the charger plug 23, effectively avoiding the phenomenon that the charger plug 23 is displaced during the plugging and unplugging tests.

[0039] Further: The buffer mechanism 11 includes a buffer plate 111 and a spring 112, and the positioning platform 7 includes a bottom plate 71, support columns 72 and a top plate 73; there are four support columns 72, and the four support columns 72 are respectively fixedly installed at the four ends of the bottom side of the top plate 73, and the bottom ends of the support columns 72 are fixedly installed on the bottom plate 71, and the bottom plate 71 is fixedly installed on the machine table 1; four guide sleeves 29 are fixedly installed on the buffer plate 111, and the guide sleeves 29 are slidably fitted on the support columns 72 one by one. There are four springs 112, and the four springs 112 are respectively abutted and installed between the four ends of the bottom side of the buffer plate 111 and the bottom plate 71; a right-angled vertical plate 30 is formed on the bottom side of the front end of the U-shaped bracket 12, and the right-angled vertical plate 30 is fixedly installed on the front side of the buffer plate 111; the buffer mechanism 11 can be used to provide elastic buffering for the U-shaped bracket, and can avoid damaging the USB female socket 25 of the charger plug 23 when the data line 24 is misaligned.

[0040] It should be noted that: the lifting stroke of the Z-axis pusher 4 driving the wire clamp 6 should be less than the depth of the USB female socket 25, so the port of the data line 24 will not be completely separated from the USB female socket 25 during insertion and extraction, so that the phenomenon that it cannot be reinserted into the USB female socket 25 due to inclination will not occur after the data line 24 is pulled out. Coupled with the random inclination of this application, the random inclination insertion and extraction test is realized, which can simulate the actual situation of normal use of the charger plug 23 in real life and ensure the accuracy of the insertion and extraction test.

[0041] This embodiment does not make any formal restrictions on the shape, material, structure, etc. of the present invention. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention all belong to the protection scope of the technical solution of the present invention.
