[0001] This invention relates to the field of pull-out testing, and more particularly to an automated pull-out testing device. Background Technology

[0002] After the Type-C plug is connected and fixed to the Type-C interface, a pull-out test is required to check the stability of the Type-C plug connection and ensure product quality.

[0003] For example, Chinese patent CN118347927A discloses a plug pull-out detection device, which uses a turntable to drive multiple Type-C plugs to rotate sequentially to the bottom of the Type-C interface, realizing rapid switching of multiple Type-C plugs during the testing process, replacing manual switching, and improving switching accuracy and efficiency. However, it has the following defects: During the automated pull-out test, the Type-C plug and the Type-C interface are connected and fixed by an electric drive push rod. The electric drive push rod is a rigid push. When the Type-C plug is damaged or deformed during production or transportation, the Type-C plug cannot be inserted into the Type-C interface. The rigid push of the electric drive push rod into the Type-C interface can easily damage the Type-C interface. Summary of the Invention

Detailed Implementation

[0023] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0024] Example 1: An automated pull-out testing device, such as Figures 1-5 As shown, the system includes a base 1, a telescopic drive component 4, a tension sensor 5, and an upper fixed seat 6. The telescopic drive component 4, an electrically driven push rod, is mounted on the top of the base 1. A tension sensor 5 is mounted on the driving end of the telescopic drive component 4. The upper fixed seat 6 is mounted on the detection end of the tension sensor 5. The system also includes a rotating assembly, a second telescopic drive component 7, a lower fixed seat 10, and a buffer assembly. A rotating assembly is mounted on the bottom of the base 1. Multiple second telescopic drive components 7, electrically driven push rods, are mounted on the rotating part of the rotating assembly. Each second telescopic drive component 7 has a lower fixed seat 10 mounted on its driving end, located below the upper fixed seat 6. A buffer assembly connects each second telescopic drive component 7 to its corresponding lower fixed seat 10.

[0025] The rotating assembly includes a rotating drive component 2 and a mounting plate 3; the rotating drive component 2 is mounted on the base 1, and the rotating drive component 2 is a motor; the driving end of the rotating drive component 2 is mounted on the mounting plate 3; all the telescopic drive components 7 are mounted in a circular array on the mounting plate 3.

[0026] The buffer assembly includes a mounting base 8 and an elastic telescopic rod 9; each of the telescopic drive components 7 has a mounting base 8 installed at its drive end; one end of an elastic telescopic rod 9 is connected to each mounting base 8; the other end of the elastic telescopic rod 9 is connected to the corresponding lower fixed base 10.

[0027] An outer cover 12 is installed on the mounting base 8; the outer cover 12 surrounds the outer side of the elastic telescopic rod 9 and the lower fixed base 10; a locking structure is provided between the outer cover 12 and the corresponding lower fixed base 10.

[0028] The lower fixing seat 10 has a groove 102 on its side, and a spring bead 103 is installed in the groove 102. The outer cover 12 has a through groove 121 on its side. The locking structure is composed of the spring bead 103 and the through groove 121.

[0029] The top of the inner wall of the outer casing 12 is provided with a groove 122, and a heating tube 13 is installed in the groove 122.

[0030] The outer casing 12 is made of transparent material, making it easy for staff to observe.

[0031] The telescopic drive component 2 7, mounting base 8, elastic telescopic rod 9, lower fixed base 10, spring ball 103, rotating clamp 11, outer cover 12 and heating tube 13 are all shown in four examples, and are divided into four groups.

[0032] In this embodiment, the operator places the test interface with the opening facing downwards inside the upper fixed seat 6 and fixes it. By controlling the rotation drive 2 to drive the mounting plate 3 to rotate, the mounting plate 3 drives the four telescopic drive 7 to rotate and adjust their positions, so that the four lower fixed seats 10 can rotate in turn, making it convenient for the operator to place the plug into the lower fixed seat 10 one by one with the head facing upwards. The lower fixed seats 10 with the plug placed are rotated and moved one by one to the bottom of the upper fixed seat 6. When the lower fixed seat 10 with the plug placed and fixed is moved directly below the upper fixed seat 6, the telescopic drive 7 is controlled to push the mounting seat 8, the elastic telescopic rod 9, the lower fixed seat 10 and the plug on the lower fixed seat 10 upwards, so that the plug can be inserted upwards into the interface inside the upper fixed seat 6, thus completing the preparation for the pull-out test. Then, the telescopic drive 4 is controlled to pull the tension sensor 5, the upper fixed seat 6 and the interface inside the upper fixed seat 6 upwards, so that the interface can be separated from the plug. The tension sensor 5 detects the tension data during the separation process, thus completing the pull-out test.

[0033] When the plug is damaged or deformed and cannot be inserted into the interface, in this case, when the lower fixing seat 10 moves the plug upward to contact the interface, the telescopic drive component 7 continues to push the mounting seat 8 upward. Since the lower fixing seat 10 and the plug cannot move upward, the upward movement of the mounting seat 8 compresses the elastic telescopic rod 9, and the mounting seat 8 moves the outer cover 12 upward until the spring ball 103 in the groove 102 aligns with the through slot 121 of the outer cover 12 and pops out from the through slot 121. The operator observes; if the spring ball 103 has popped out from the through slot 121, but the plug is not fully inserted into the interface, it indicates that the plug is damaged or deformed and needs to be removed. To remove the damaged or deformed plug, the telescopic drive component 7 is controlled to move the mounting base 8 downwards, causing the lower fixing base 10 and the plug to move downwards. Then, the operator can press the spring bead 103, causing it to retract back into the groove 102. Utilizing the rebound effect of the elastic telescopic rod 9, the lower fixing base 10 is moved upwards again to its initial state, with its upper surface flush with the upper surface of the outer casing 12. The operator can then remove the damaged or deformed plug and replace it with a new plug to be tested. Thus, through the design of the mounting base 8 and the elastic telescopic rod 9, elastic buffering is achieved during the plug insertion process into the interface, avoiding additional damage caused by forced insertion.

[0034] It should be noted that the resistance when the plug is inserted into the interface normally cannot cause the elastic telescopic rod 9 to be compressed significantly.

[0035] It should be noted that the telescopic principle of the spring bead 103 is the same as the telescopic fixing principle of the umbrella handle. The spring bead 103 consists of a rod and a hemispherical end. When the spring bead 103 pops out into the through groove 121, the rod part of the spring bead 103 is located in the through groove 121. Only by manually pressing the hemispherical end of the spring bead 103 will the spring bead 103 retract. Therefore, it will not affect the pull-out test of the plug and interface.

[0036] Furthermore, considering that electronic devices generate heat during use, the plug and interface are in a very low-temperature environment when plugged in. Existing pull-out tests are conducted at room temperature, which cannot reflect pull-out data under extremely high-temperature conditions. Therefore, in this invention, a heating element 13 is added. When the plug can be properly inserted into the interface, the telescopic drive component 7 continues to push the mounting base 8 upwards. Since the plug is properly inserted into the interface and remains stationary, the mounting base 8 continues to move upwards, compressing the elastic telescopic rod 9. Simultaneously, the mounting base 8 drives the outer casing 12 to move upwards, causing the spring ball 103 to pop out from the through slot 121 to lock the lower fixing base 10 and the outer casing 12. The outer casing 12 then moves upwards above the lower fixing base 10. At this point, a space is formed between the upper fixing base 6 and the lower fixing base 10 for plug-in interface insertion, thus allowing the outer casing 12 to be higher than the lower fixing base 10. The outer casing 12 partially surrounds the space between the upper fixed seat 6 and the lower fixed seat 10. At this time, the heating tube 13 in the groove 122 is located at the part of the outer casing 12 that is higher than the lower fixed seat 10. Then, the heating tube 13 is activated, and the space between the upper fixed seat 6 and the lower fixed seat 10 is brought to a specified temperature environment by the heating tube 13. Then, the telescopic drive 4 is activated to pull the upper fixed seat 6 and the interface for a pull-out test. The process of removing the plug is the same as the above principle. The operator presses the spring bead 103, so that the lower fixed seat 10 bounces upward under the elastic telescopic rod 9. This simulates a very low temperature environment during the pull-out process, so that the pull-out data can better reflect the real user experience. Moreover, the outer casing 12 reduces heat leakage and energy consumption by surrounding the plug. When testing multiple plugs, the heating tubes 13 can be heated to different temperatures for comparison testing.

[0037] During daily storage, the outer casing 12 can seal and protect the heating tube 13, achieving dust prevention and impact protection. In addition, the outer casing 12 can cover most of the elastic telescopic rod 9, also achieving dust prevention.

[0038] Example 2: Based on Example 1, such as Figures 1-5As shown, the upper fixing seat 6 has a fixing groove 63 at its bottom. The upper fixing seat 6 is screwed with a fixing bolt 61. The screw end of the fixing bolt 61 passes into the fixing groove 63 and is connected to a fixing piece 62. The head of the fixing bolt 61 protrudes outside the upper fixing seat 6.

[0039] The lower fixing seat 10 has a fixing groove 2 101 on its top, and two symmetrically arranged rotating clamps 11 are installed on the top of the lower fixing seat 10; the two rotating clamps 11 are respectively located on both sides of the fixing groove 2 101.

[0040] When the two rotating clamps 11 are rotated to a horizontal position, they cover the opening of the fixing groove 101.

[0041] In this embodiment, the operator places the interface to be tested in the fixing slot 63 and rotates the fixing bolt 61 to move the fixing plate 62, so that the fixing plate 62 moves to contact the interface and squeezes and fixes the interface. Afterwards, when removing the interface, simply rotate the fixing bolt 61 in the opposite direction.

[0042] Furthermore, the staff places the plug to be tested in the fixing slot 2 101, and then controls the micro motor on the lower fixing base 10 to drive the rotating clamp 11 to rotate, so that the two rotating clamps 11 rotate to clamp the plug, thereby fixing the plug. Afterwards, when removing the plug, simply control the two rotating clamps 11 to rotate in the opposite direction to release the plug. In addition, when not being tested, the two rotating clamps 11 are controlled to rotate horizontally to cover and block the opening of the fixing slot 2 101, reducing dust from entering the fixing slot 2 101 with the opening facing upward, thus reducing maintenance workload. During testing, simply rotate the rotating clamps 11 upward.
