[0002] With the development of science and technology, mobile phones have become an indispensable communication tool in people's lives. However, when using a mobile phone, the data cable will become loose when it is plugged and unplugged many times. Therefore, before the mobile phone leaves the factory, it is necessary to conduct a data cable interface plug-in test on the mobile phone sample to detect whether the data cable interface of the mobile phone can reach the qualified plug-in and unplug times. If manual testing is used, the test efficiency is low, the measurement results are inaccurate, and manpower is greatly wasted.

[0003] At the same time, with the current multi-directional testing of mobile phones, it is necessary to simulate the charging and plugging detection of mobile phones in different environments.

DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-Figure 8 , an automatic plug-in and pull-out test device for a mobile phone charging port, comprising a test stand 1; a fixed table 4; a test component 3, used for performing a cyclic plug-in and pull-out test on a mobile phone charging port; a drive component 2, used for providing a cyclic driving force for the test component 3; a high-temperature switching component 7, used for continuously switching the plug-in and pull-out test environment of the mobile phone charging port; the test component 3 comprises a push rod 301, the push rod 301 is mounted on the drive component 2, a tripod 302 is mounted on the left side of the push rod 301, a plurality of different types of charging heads are mounted on the tripod 302, an organic slot 5 is provided on the fixed table 4, and a mobile phone to be tested is placed in the organic slot 5.

[0021] In this embodiment, the driving assembly 2 includes a driving motor 201, the output end of the driving motor 201 is fixedly connected to a driving wheel 202, the eccentric position of the driving wheel 202 is connected to a bearing wheel 203, the surface of the bearing wheel 203 is slidably connected to a sliding seat 204, the sliding seat 204 is slidably connected to the test frame 1 through a slide rail, and the push rod 301 is installed on the sliding seat 204. The rotation of the driving motor 201 drives the rotation of the driving wheel 202. At this time, the bearing wheel 203 located at the eccentric position will move in a circular motion, driving the sliding seat 204 to move horizontally to the left and right. After that, the sliding seat 204 drives the push rod 301 to reciprocate left and right under the sliding restriction of the slide rail, and the push rod 301 will drive the charging head on the tripod 302 to be inserted horizontally into the charging port position of the mobile phone, realizing plug-in reciprocating motion, and then performing high-frequency testing on the position of the mobile phone charging port.

[0022] Furthermore, a spiral groove 304 and a straight groove 305 are provided on the push rod 301. The straight groove 305 is connected to the two spiral grooves 304. A limit pin 307 is slidably connected to the straight groove 305. A rotating piece 308 is fixedly connected to the limit pin 307. The left end of the rotating piece 308 is rotatably connected to the test frame 1. The bottom of the rotating piece 308 is connected to the extrusion spring 306, and the bottom of the extrusion spring 306 is connected to the test frame 1. When the push rod 301 moves laterally, the limit pin 307 will slide inside the straight groove 305, so the position of the push rod 301 when inserted will remain unchanged. When it is reset and pulled out, the extrusion spring 306 will provide a downward pulling force for the rotating piece 308, thereby driving the limit pin 307 to have a downward pressure. Then, as the push rod 301 returns to its original position, the limit pin 307 will be controlled to enter the entrance position of the spiral groove 304. At this time, when the push rod 301 continues to return to its original position, the sliding of the limit pin 307 in the spiral groove 304 will drive the push rod 301 to rotate 180 degrees, thereby driving the charging head on the tripod 302 to flip over, realizing repeated plugging and unplugging tests after flipping, and then simulating the cyclic flip charging test of the charging head.

[0023] Furthermore, the push rod 301 is provided with a sliding groove 310 and a card slot 311, and the middle of the tripod 302 is connected with a center rod 303, the center rod 303 is slidably connected in the sliding groove 310, and the tripod 302 is carded in the card slot 311. Because there are currently multiple standards for the location of the charging port of a mobile phone, including a type-c interface and a Lightning interface, if a mobile phone with a different charging port is used, the center rod 303 can be slid to the left and the tripod 302 can be rotated to align the corresponding charging head with the test station, and then slid to the right to card it inside the card slot 311 for fixation, thereby improving the diversity of product testing options.

[0024] In addition, a water tank 9 is provided inside the fixed platform 4, and an aqueous solution is provided inside the water tank 9. A piston plate 10 is slidably connected to the inner wall of the water tank 9, and a push rod 8 is fixedly connected to the right side of the piston plate 10. The right end of the push rod 8 is connected to the push rod 301. A water outlet tank 11 is provided on the fixed platform 4, and the water outlet tank 11 is located inside the machine tank 5. When the push rod 301 is inserted and moved, the piston plate 10 will be driven to move through the connection of the push rod 8, and then the aqueous solution will be squeezed from the inside of the water tank 9 into the mouth of the water outlet tank 11 by the piston extrusion and discharged, and then soaked on the entire test mobile phone, providing charging port plug-in detection in a soaked state.

[0025] In addition, the high temperature switching assembly 7 includes a cover plate 6, which is rotatably connected to the fixed platform 4, and a hollow plate 701 is slidably connected inside the cover plate 6. A heating tube 703 is arranged inside the hollow plate 701, and a collar 312 is rotatably connected to the push rod 301, and a push rod 313 is connected to the collar 312. A positioning frame 309 is slidably connected to the collar 312 through a key slot, and the positioning frame 309 is fixed on the test frame 1. The heating tube 703 can provide a heating environment to radiate to the inside of the machine slot 5, heat up the mobile phone, and then simulate the charging port plug-in test state when the mobile phone is heated. And the setting of the push rod 313 can promote the hiding and popping out of the hollow plate 701. The whole process is similar to the principle of the "drawer" press type. Popping out forms a closed heating space, and shrinking forms an open normal temperature test environment.

[0026] It is worth noting that a tail frame 704 is fixedly connected to the left side of the cover plate 6, and a guide rod 705 is slidably connected to the tail frame 704. A compression spring 706 is sleeved on the surface of the guide rod 705, and the compression spring 706 is located between the hollow plate 701 and the tail frame 704. A sliding plate 707 is slidably connected to the tail frame 704. A locking groove 711 is provided on the sliding plate 707, and a locking pin 710 is slidably connected in the locking groove 711. A rocker arm 709 is connected to the locking pin 710, and the rocker arm 709 is rotatably connected to the tail frame 704. A pull rod 708 is slidably connected to the tail frame 704, and one end of the pull rod 708 is connected to the hollow plate 701, and the other end of the pull rod 708 is connected to the sliding plate 707. The push rod 301 will synchronously drive the shaft ring 312 to move, drive the push rod 313 to move forward, and abut against the position of the hollow plate 701, thereby controlling the hollow plate 701 to move left, squeezing the compression spring 706, and driving the sliding plate 707 to slide inside the tail frame 704 through the pull rod 708. The sliding of the sliding plate 707 will be through the special structure of the locking groove 711, so that the locking pin 710 is locked in the notch position of the leftmost and rightmost ends of the locking groove 711, and the hollow plate 701 is positioned after contraction and expansion, making the overall simulation environment more stable.

[0027] It is worth noting that a heat-insulating plate 712 is fixedly connected to the bottom of the hollow plate 701, and a ventilation groove 702 is provided on the hollow plate 701. Two guide rods 705 and two compression springs 706 are provided, and the two guide rods 705 and compression springs 706 are symmetrically distributed with the center line of the tail frame 704 as the symmetry axis. The provision of the heat-insulating plate 712 can isolate the temperature when the hollow plate 701 contracts, so that the entire heating tube 703 is in a closed environment, and then the ventilation groove 702 is used to dissipate the temperature of the air heated last time, ensuring that the internal hot air of the machine slot 5 can be dissipated at this time, and is in a normal temperature state, which is convenient for subsequent plug-in and unplug tests at normal temperature.

[0028] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0029] Working principle: first, at the beginning of the test, the mobile phone to be tested needs to be placed inside the machine slot 5, locked in place, and the position of the mobile phone charging port is facing the push rod 301, and then the drive motor 201 is started to rotate, driving the drive wheel 202 to rotate. At this time, the bearing wheel 203 located in the eccentric position will move in a circular motion, driving the sliding seat 204 to move horizontally to the left and right. After that, the sliding seat 204 drives the push rod 301 to reciprocate left and right under the sliding restriction of the slide rail, and the push rod 301 will drive the charging head on the tripod 302 to be inserted horizontally into the charging port position of the mobile phone to achieve insertion. After that, during the reset movement, it will drive the charging head to be pulled out, and the whole realizes reciprocating automatic plugging and unplugging. The technical solution also provides a spiral groove 304 and a straight groove 305, mainly to control the 180-degree flipping of the tripod 302 each time, because the charging port of the mobile phone can be inserted forwards and backwards, but when the user uses it for too long, it may not be charged when inserted forwards, and it will only work when inserted backwards, which indicates that there is a certain problem with the position of the mobile phone charging port. Therefore, the solution sets the forward and reverse plug-in synchronization in the automatic test environment. Specifically, when the push rod 301 moves horizontally, the limit pin 307 will slide inside the straight groove 305, so it will limit the insertion of the push rod 301 The position remains unchanged, and when it is reset and pulled out, the extrusion spring 306 will provide a downward pulling force for the rotating piece 308, thereby driving the limit pin 307 to have a downward pressure, and then as the push rod 301 returns to its original position, it will control the limit pin 307 to enter the entrance position of the spiral groove 304. At this time, when the push rod 301 continues to return to its original position, the sliding of the limit pin 307 in the spiral groove 304 will drive the push rod 301 to rotate 180 degrees, and then drive the charging head on the tripod 302 to flip over, realizing repeated plugging and unplugging tests after flipping, and then simulating the cyclic flip charging test of the charging head. A water tank 9 is provided in the fixed platform 4. When the push rod 301 is inserted and moved, the piston plate 10 will be driven to move through the connection of the push rod 8, and then the aqueous solution will be squeezed from the inside of the water tank 9 into the mouth of the water tank 11 through the piston extrusion, and then soaked on the entire test mobile phone, providing a charging port plug-in detection in a soaked state, and the outflowing water will flow back to the inside of the water tank 9 again, and then as the piston plate 10 returns to its position, it will squeeze the aqueous solution inside the right water tank 9. After reaching the opening position, the aqueous solution will overflow the height of the piston plate 10 and re-enter the left side of the water tank 9 to provide an environment for the next soaking. Of course, the operator can also choose not to soak the environment, as long as the water tank 9 is not filled with water.The technical solution also provides a high temperature switching component 7, which is mainly used to provide a more complex high temperature environment for testing. However, the high temperature environment can be switched with the plug-in cycle to achieve environmental scene switching. When a high temperature environment switching test is required, the cover plate 6 needs to be placed on the fixed platform 4. Then, with the first insertion test, the push rod 301 will synchronously drive the shaft ring 312 to move. Although the push rod 301 is rotating, the shaft ring 312 is limited to sliding in the left and right directions due to the key slot, thereby driving the push rod 313 to move forward, and the forward movement of the push rod 313 will abut against the empty space. The position of the core plate 701 is controlled, thereby controlling the hollow plate 701 to move left, squeezing the compression spring 706, and driving the sliding plate 707 to slide inside the tail frame 704 through the pull rod 708. The sliding of the sliding plate 707 is set by the special structure of the locking groove 711, so that the locking pin 710 is locked in the slot position at the far left and right ends of the locking groove 711. Therefore, when the hollow plate 701 is pressed, the locking pin 710 is controlled to slide to the hypotenuse slot of the locking groove 711, thereby driving the swing rod 709 to swing at the connection point position of the tail frame 704, driving the locking pin 710 to slide and enter the rightmost side. When the push rod 301 is reset to the right, the air permeable groove 702 on the hollow plate 701 will coincide with the groove on the cover plate 6. At this time, the machine slot 5 will be in a connected state with the outside world, and the insulation plate 712 will abut against the inside of the cover plate 6, so that the heating tube 703 is hidden inside the cover plate 6 and the radiation temperature of the heating tube 703 is isolated. Only when the hollow plate 701 is pressed again, the sliding plate 707 is driven to move, so that the latch pin 710 is disengaged from the right convex groove position of the rightmost locking groove 711, and then with the elasticity of the compression spring 706, The force stretching will drive the hollow plate 701 to pop out, and then control the latch 710 to move to the groove mouth position of the leftmost latch slot 711. At this time, after the hollow plate 701 pops out, it will drive the internal heating tube 703 to move right and be exposed, and the hollow plate 701 will fill the groove of the cover plate 6, and the air permeable groove 702 will be hidden deep inside the cover plate 6. At this time, the cover plate 6 will form a closed flip cover, and the heating tube 703 will radiate heat to the entire mobile phone, simulating the charging state of the mobile phone under high temperature, so as to finally realize the continuous conversion between normal temperature and high temperature, and the plug-in cycle test of the charging port.

[0030] In summary, through changes in multiple simulated environments, the position of the mobile phone charging port is plugged in and tested, thereby testing the overall charging status and charging performance of the mobile phone. Compared with the traditional plug-in straight insertion, this technical solution is more stringent in testing the charging port of the mobile phone and can better test the problems of the mobile phone charging port.
