In general, the terms "comprises" and "comprising" merely indicate that steps and elements are included which are explicitly identified, that the steps and elements do not form an exclusive list, and that a method or apparatus may include other steps or elements.

It will be appreciated that if the device of the icon were turned upside down, the element described as "upper" would become the element "lower". When a structure is "on" another structure, it may mean that the structure is integrally formed with the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via another structure.
Before describing the detailed description of the card tray detection method provided by the embodiment of the present application, the terms and related technologies related to the embodiment of the present application will be briefly described.
Referring to fig. 1, fig. 1 is a terminal with a card holder structure in the related art, as shown in fig. 1, a card holder (not shown) is disposed in a frame of a terminal 10, a card holder 101 is generally used for placing a SIM card or a Secure Digital (SD) card, etc., and is mounted in the card holder, a card holder ejection mechanism is disposed in the card holder, and when the SIM card or the memory card mounted in the terminal needs to be replaced, a card taking method is generally adopted: the card holder is ejected out of the card bracket by inserting the card taking hole, and the card taking operation is carried out. In fig. 1, the card holder 101 is a SIM card holder, and is provided with an ejector pin hole 102, when a card needs to be taken or replaced, an ejector pin is inserted into the ejector pin hole 102, and a card holder ejecting device (not shown) is pressed, so that the card holder 101 can be ejected from the card holder.
In the existing terminal assembly production line, a tester randomly matches an SIM card support with a terminal body, manually ejects out an SIM card by using a spring ejector pin after the SIM card support is manually inserted into a terminal so as to check whether an SIM card ejection mechanism in the terminal is normal or not and whether ejection hand feeling (ejection force) is normal or not. The spring in the spring thimble is equipped with the maximum stroke for thimble ejecting power is not more than the setting value, in order to prevent that ejection mechanism card from dying back, and the too big ejection dynamics of tester leads to ejection mechanism even the mainboard further to damage.
The prior art has the following defects: the tester holds in the palm the SIM card by hand and inserts the terminal, and the inserting dynamics and the depth of insertion that the uncontrollable card held in the palm can't prevent slow-witted simultaneously manually operation, probably causes phenomenons such as lou examined: 1) if foreign matters in the SIM card slot are blocked, the internal ejection mechanism or the mainboard is easily damaged due to overlarge force for inserting the card support; 2) if the size of the SIM card support is larger, the card support and the card support groove are too tightly matched, a tester forcibly inserts the card support, the situation that the spring thimble cannot eject the card support can be caused, at the moment, the hard thimble must be used for forcibly ejecting the card support, the forced ejection force is too large, and the damage to an internal ejection mechanism is easily caused. If the card support cannot be ejected after the ejection mechanism is damaged, disassembly and maintenance are required, so that the maintenance cost is increased; 3) if the size of the SIM card support is larger, the card support is over tightly matched with the card support groove, but a tester does not insert the card support into the card support groove completely, and then the spring thimble is used for ejecting the card support. At the moment, the tester can think that the ejecting hand feeling of the card support is normal, and defective products flow out. When the card support is used by a user, the card support is found to be difficult to eject after being completely inserted, and the ejection mechanism is damaged due to overlarge ejection force, so that the user needs to perform after-sale maintenance, the after-sale maintenance cost is increased, and the brand reputation is influenced.
Based on at least one of the above problems in the related art, the embodiments of the present application provide a card holder detection device, which can automatically complete a series of actions, such as "eject the card holder with a thimble," detect the state of the ejected position of the card holder, "and push back the card holder," to avoid bad outflow due to errors of a tester in the actions, thereby achieving fool-proofing.

If the insertion is not forced to be inserted under the conditions of over-tightness, no insertion and the like, defective products are reserved and fed back.
Step S802, fixing the terminal to be detected in the card holder detection device.
Here, when the terminal 10 to be tested is placed, attention is paid to placing the terminal against the stopper 302 of the fixing module 22. The terminal 10 to be tested can be in a bare state, or a special protective case can be designed to be put into the range limited by the fixing module 22 while wearing the protective case in a state of ensuring positioning and exposing the SIM card holder 101.
In step S803, the reset start button is pressed.
Here, after the terminal 10 to be tested inserted into the card holder 101 is fixed to the card holder detection device 20 by the fixing module, the reset start button 2114 on the base 21 is pressed.
Step S804, the push rod extends out of the set stroke to push the card holder.
Here, in response to the reset start button, the jig is pressed down to fix the terminal to be tested while the push rod of the reset module 25 is extended, and the card holder 101 is pushed into the card holder groove by a set stroke. During the pushing process, the force sensor in the reset module 25 measures the pushing resistance and records the change curve of the pushing resistance along with the time in the whole pushing process.
Step S805, it is determined whether the push rod push resistance test is successful.
Here, when the pushing force of the push rod is greater than a set threshold (the set threshold is determined by a value which is obtained by a previous experiment and can cause the SIM card holder 101 or the internal mechanism of the terminal 10 to be tested to fail), it is determined that the push rod pushing resistance test fails, and at this time, the force sensor sends an instruction to stop the operation of the motor which controls the push rod, and step S806 is executed to stop the test flow; otherwise, step S807 is executed to continue to complete the testing process.
In step S806, the screen displays "the push-rod push resistance test failed".

And step S809, judging whether the thimble pushing resistance test is successful.
Here, when the resistance in the pushing process of the thimble is greater than a certain set threshold (the set threshold is determined by a value which is obtained by a previous experiment and can cause the internal mechanism of the terminal 10 to be tested to fail), it is determined that the thimble pushing resistance test fails, and at this time, the force sensor sends out an instruction to cause the motor controlling the thimble to stop working, and step S810 is executed to stop the test; otherwise, if the thimble push resistance test is determined to be OK, step S811 is executed to continue the test.
Step S810, displaying on the screen that the thimble push resistance test fails.
Here, the gripper 27 is in the released state, and the screen 105 displays "the thimble-pushing resistance test failed".
Step S811, the thimble retracts automatically, and the card holder is ejected.
Here, if the thimble module 23 pushes the resistance test OK, the thimble module 23 is automatically retracted. At this time, normally, card holder 101 should have been ejected.
In step S812, it is determined whether the card holder is ejected to the designated position.
Here, the infrared emitter of the positioning module 24 emits light, and the infrared receiver determines whether the card holder is ejected out of the designated position by measuring the intensity of the received light and comparing the measured intensity with a set value (the set value is determined by the intensity of infrared light that the infrared receiver can receive when the card holder is ejected out normally according to the previous experiment).
If the intensity of the received light is greater than the set value, judging that the card holder is not ejected out of the designated position, executing step S813, and stopping the testing process; otherwise, if the card holder is pushed out of the designated position, step S814 is executed to continue to complete the testing process.
In step S813, the screen displays "the card holder is not ejected to the designated position".
Here, when the light intensity is out of the defined range, the clamp 27 is released, and the screen 105 displays "the card holder is not ejected to the designated position".
In step S814, the push rod automatically pushes the card holder back to the card holder slot.
Here, if the card holder 101 is ejected to a designated position, the reset module 25 automatically pushes the card holder 101 back into the card holder slot of the terminal 10 to be tested.
And step S815, taking down the terminal to be tested from the positioning mould.
Here, after the jig 27 is released and the terminal 10 to be tested is removed from the positioning mold 301, the terminal 10 to be tested flows to the next station, and thus the entire automatic inspection process is completed.
