Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone card tray quality inspection, and particularly to a mobile phone card tray quality inspection device and method. Background Art

[0002] With the rapid development of mobile communication technology and the popularization of smart phones, users' requirements for the quality of mobile phone accessories are also increasing day by day; as a key small component of a mobile phone, the mobile phone card tray undertakes the important task of fixing the SIM card and accurately inserting it into the mobile phone main board slot. Therefore, its structural design and material properties directly affect the user experience and the stability of the SIM card connection. In the production and manufacturing process, the mobile phone card tray is usually made of metal or polymer materials and has a certain locking function to ensure that the mobile phone card tray can be firmly locked in the mobile phone. In order to ensure the reliability and durability of the mobile phone card tray in actual use, it is necessary to conduct strict quality inspections by sampling before leaving the factory, especially for the fatigue resistance of its locking mechanism.

[0003] Currently, a commonly used test method in the industry is a cyclic test that simulates the user's plugging and unplugging operations. This method simulates the operation process in a real use environment by repeatedly performing the actions of "insertion - locking - ejection". During the test process, a standard number of times is usually set to evaluate whether the mobile phone card tray can still maintain a good locking function after long-term use. After reaching the standard number of times, manual observation is used to determine whether the quality of the mobile phone card tray is qualified; however, in the above method, firstly, traditional detection devices are mostly semi-automatic or manual operations, relying on manual judgment of results, with low efficiency and difficult to meet the requirements of modern large-scale production lines for rhythm and production capacity; secondly, the existing test method only uses the set number of times as the qualification standard and cannot further test the exact limit number of uses before the card tray fails functionally, thus limiting the performance optimization and material selection in the product R & D stage. Summary of the Invention

[0004] In view of this, the present invention provides a mobile phone card tray quality inspection device and method, which can solve the disadvantages of the existing method in detecting the quality of the mobile phone card tray, such as low efficiency, difficult to meet the requirements of modern large-scale production lines for rhythm and production capacity, and unable to test the exact limit number of uses before the card tray fails functionally.

[0005] The technical solution is as follows: A mobile phone card tray quality detection device includes a support platform and a controller. The controller is installed on the side of the support platform. A simulation part is arranged on the support platform. A card slot is opened on the simulation part. A guide rail frame is slidably arranged on the support platform. A translation mechanism is arranged on the support platform. A sliding frame is slidably arranged on the guide rail frame. A spring is connected between the sliding frame and the guide rail frame. A hollow frame is installed on the side of the sliding frame. The hollow frame is used to store glue. A heater is arranged at the bottom of the hollow frame. The heater is used to melt the glue. The mobile phone card tray is adhered to the side of the hollow frame by the melted glue for fixation. Then, the translation mechanism drives the guide rail frame to move, so that the mobile phone card tray moves with the guide rail frame and is inserted into the card slot. A pressure sensor is also arranged on the sliding frame. The pressure sensor is used to detect the pulling force on the mobile phone card tray. An unlocking mechanism and a cutting mechanism are arranged on the guide rail frame. The unlocking mechanism is used to unlock the mobile phone card tray in the card slot, and the cutting mechanism cuts off the connection between the mobile phone card tray and the glue.

[0006] Preferably, the translation mechanism includes a motor and a lead screw. The motor is installed on the support platform. The lead screw is rotatably arranged in the support platform. The end of the lead screw is connected to the output shaft of the motor. The guide rail frame is threadedly connected to the lead screw.

[0007] Preferably, the unlocking mechanism includes a first electric push rod and a needle. The first electric push rod is installed on the guide rail frame. The needle is connected to the telescopic rod of the first electric push rod. The needle is used to unlock the mobile phone card tray in the card slot.

[0008] Preferably, the cutting mechanism includes a connecting frame, a second electric push rod and a cutter. The connecting frame is connected to the hollow frame. The connecting frame is slidably connected to the guide rail frame. The second electric push rod is installed on the connecting frame. The cutter is connected to the telescopic rod of the second electric push rod.

[0009] Preferably, a cooling mechanism is further included. The cooling mechanism includes a pipeline, a cooling box, a water pump, a first water pipe and a second water pipe. The pipeline is installed on the side of the hollow frame. The cooling box and the water pump are installed on the side of the guide rail frame. The water inlet of the water pump is communicated with the cooling box. The water outlet of the water pump is communicated with one end of the pipeline through the first water pipe. The other end of the pipeline is communicated with the cooling box through the second water pipe.

[0010] Preferably, a shielding film is further included. One end of the shielding film is connected to the support platform, and the other end of the shielding film is connected to the guide rail frame. The shielding film is used to shield the lead screw.

[0011] Preferably, a material changing mechanism is further included. The material changing mechanism includes a loading frame, a third electric push rod, a tray, a baffle, a push plate, a rotating plate, a spring piece and a discharging frame. The loading frame and the third electric push rod are installed on the support platform. The loading frame is used for loading the mobile phone card tray. A tray is slidably arranged on the support platform. The tray is connected to the telescopic rod of the third electric push rod. A baffle and a push plate are connected to the tray. The baffle is used for blocking the mobile phone card tray in the loading frame, and the push plate is used for pushing out the mobile phone card tray that has completed the detection. A rotating plate is rotatably installed on the tray. A spring piece is connected between the rotating plate and the tray. A discharging frame for discharging the mobile phone card tray is installed on the side of the support platform.

[0012] The present invention also provides a detection method for a mobile phone card tray quality detection device, including the following steps: First, load the hot melt adhesive into the hollow frame and press the right end of the mobile phone card tray against the left end of the hollow frame; Subsequently, heat the hot melt adhesive in the hollow frame through a heater so that the hot melt adhesive adheres the right end of the mobile phone card tray to the left end of the hollow frame through melting and cooling; Then, drive the guide rail frame to move leftward through the translation mechanism, driving the mobile phone card tray to be stuck into the card slot of the simulation part; After that, drive the guide rail frame to move rightward through the translation mechanism, and then operate according to the subsequent situation: If the guide rail frame cannot drive the sliding frame, the hollow frame and the mobile phone card tray to move rightward through the spring, the guide rail frame will apply a pulling force and a pressure to the spring and the pressure sensor, so that the spring uses the elastic force to apply a pulling force to the mobile phone card tray, thereby detecting whether the locking function of the mobile phone card tray can resist the pulling force, and the pressure sensor monitors the force. After the mobile phone card tray has been detected, unlock the mobile phone card tray through the unlocking mechanism, and drive the guide rail frame to move rightward and reset through the translation mechanism. After that, the controller will determine that the locking function of the mobile phone card tray is qualified after the guide rail frame moves and resets, and then repeat the above operations for multiple detections; If the guide rail frame can drive the mobile phone card tray to move rightward and reset through the spring, the mobile phone card tray will leave the card slot without being unlocked by the unlocking mechanism. In this way, the controller will determine that the locking function of the mobile phone card tray is unqualified after the guide rail frame moves and resets.

[0013] The technical implementation scheme of the present invention is as follows: 1. By using the cooperative structure of the spring and the pressure sensor, the present invention can externally pull the mobile phone card tray in the unlocked state to detect whether the locking function of the mobile phone card tray can be normally used under an appropriate pulling force, thereby automatically detecting the quality of the mobile phone card tray, which is not only time-saving and labor-saving, but also has high efficiency. Moreover, the actual number of pluggings and unpluggs of the mobile phone card tray before functional failure can be recorded during the detection process, breaking through the limitation of the traditional set standard number of times, providing real and reliable fatigue life data for R & D personnel, and contributing to material selection, structural optimization and quality improvement.

[0014] 2. By setting the cooling mechanism, the present invention can quickly reduce the temperature of the hot melt adhesive through water circulation, significantly shortening the waiting time for the hot melt adhesive to cool and improving the overall detection efficiency.

[0015] 3. By providing a material changing mechanism, the present invention can drive the tray to move back and forth through the third electric push rod, and combine the linkage mechanism of the baffle, push plate, rotating plate and elastic piece, so as to complete multiple actions of feeding, fitting and discharging at one time, greatly reducing manual intervention and realizing a fully automated detection process.

[0027] Embodiment: A mobile phone card tray quality detection device and method. Refer to Figures 1-6 As shown in the figure, it includes a support platform 1 and a controller 2; the controller 2 is installed at the right rear side of the support platform 1; it also includes a simulation part 3, a guide rail frame 4, a translation mechanism, a sliding frame 6, a spring 7, a hollow frame 8, a heater 9, a pressure sensor 10, an unlocking mechanism and a cutting mechanism; a simulation part 3 is arranged at the left front side of the top of the support platform 1, and the simulation part 3 is used to simulate a mobile phone. A card slot 301 is opened on the right side of the simulation part 3, and the card slot 301 is used to simulate the card tray slot of the mobile phone; the guide rail frame 4 is slidably arranged at the front side inside the support platform 1; a translation mechanism is arranged on the support platform 1, and the translation mechanism is used to drive the guide rail frame 4 to translate; the sliding frame 6 is slidably arranged on the upper side of the guide rail frame 4, and two springs 7 are connected between the left side inside the sliding frame 6 and the upper left side of the guide rail frame 4; the hollow frame 8 is installed on the left side of the sliding frame 6, and the hollow frame 8 is used to store glue; the heater 9 is arranged at the bottom of the hollow frame 8, and the heater 9 is electrically connected to the controller 2. The heater 9 is used to melt the glue, and the mobile phone card tray 101 is adhered to the left side of the hollow frame 8 by melting the glue for fixation. Then, the translation mechanism drives the guide rail frame 4 to move, so that the mobile phone card tray 101 moves with the guide rail frame 4 and is inserted into the card slot 301; the pressure sensor 10 is arranged on the right side inside the sliding frame 6, and the pressure sensor 10 is electrically connected to the controller 2. The pressure sensor 10 is used to detect the pulling force on the mobile phone card tray 101; the unlocking mechanism and the cutting mechanism are arranged on the guide rail frame 4. The unlocking mechanism is used to unlock the mobile phone card tray 101 in the card slot 301, so that the mobile phone card tray 101 can normally pop out of the card slot 301, and the cutting mechanism cuts off the connection between the mobile phone card tray 101 and the glue, so as to detect the next mobile phone card tray 101.

[0028] Refer to Figure 2 As shown in the figure, the translation mechanism includes a motor 501 and a lead screw 502; the motor 501 is installed on the support platform 1, and the motor 501 is installed at the left front side of the bottom of the support platform 1. The motor 501 is electrically connected to the controller 2; the lead screw 502 is rotatably installed at the front side inside the support platform 1, the left end of the lead screw 502 is connected to the output shaft of the motor 501, and the guide rail frame 4 is threadedly connected to the lead screw 502.

[0029] Refer to Figure 4 As shown in the figure, the unlocking mechanism includes a first electric push rod 1101 and a needle 1102; the first electric push rod 1101 is installed at the rear part of the upper side of the guide rail frame 4, the first electric push rod 1101 is electrically connected to the controller 2, and the needle 1102 is connected to the telescopic rod of the first electric push rod 1101. The needle 1102 is used to unlock the mobile phone card tray 101 in the card slot 301.

[0030] Refer to Figure 5As shown in the figure, the cutting mechanism includes a connecting frame 1201, a second electric push rod 1202 and a cutter 1203; the connecting frame 1201 is connected to the hollow frame 8, and the connecting frame 1201 is slidably connected to the guide rail frame 4; two second electric push rods 1202 are installed on the left part of the lower side of the connecting frame 1201, and the second electric push rods 1202 are electrically connected to the controller 2; a cutter 1203 is connected between the telescopic rods of the two second electric push rods 1202, the cutter 1203 contacts the lower left side of the hollow frame 8, and the left side surface of the cutter 1203 is flush with the left side surface of the hollow frame 8.

[0031] During use, first load the hot melt adhesive into the hollow frame 8, then press the right end of the mobile phone card tray 101 against the left end of the hollow frame 8, and then control the heater 9 to heat the hot melt adhesive in the hollow frame 8 through the controller 2 until the hot melt adhesive melts, so that the melted hot melt adhesive contacts the right end of the mobile phone card tray 101, and then wait for the hot melt adhesive to cool down, so that the hot melt adhesive sticks the right end of the mobile phone card tray 101 to the left end of the hollow frame 8 (as Figure 6 shown in the figure). In this way, the mobile phone card tray 101 can be fixed. Then, control the motor 501 to drive the lead screw 502 to rotate through the controller 2, so that the lead screw 502 drives the guide rail frame 4 to move to the left, so that the guide rail frame 4 drives the sliding frame 6, the hollow frame 8 and the mobile phone card tray 101 to move to the left through the spring 7 until the mobile phone card tray 101 is inserted into the card slot 301 of the simulation part 3, so that the mobile phone card tray 101 is locked in the card slot 301. Then, control the motor 501 to drive the lead screw 502 to reverse through the controller 2, so that the lead screw 502 drives the guide rail frame 4 to move to the right. Then, it is divided into two cases: If the guide rail frame 4 fails to drive the sliding frame 6, the hollow frame 8, and the mobile phone card tray 101 to move to the right through the spring 7, the guide rail frame 4 will pull the spring 7, causing the spring 7 to stretch and the elastic force of the spring 7 to gradually increase. After the spring 7 stretches, the spring 7 will apply a pulling force to the sliding frame 6, the hollow frame 8, and the mobile phone card tray 101 using the elastic force, and the applied pulling force will gradually increase with the elastic force of the spring 7. This is used to detect whether the locking function of the mobile phone card tray 101 can withstand the pulling force. When the guide rail frame 4 moves to the right and contacts the pressure sensor 10, the guide rail frame 4 will apply pressure to the pressure sensor 10, causing the pressure sensed by the pressure sensor 10 to gradually increase. When the pressure sensed by the pressure sensor 10 is greater than the preset value, the pressure sensor 10 will send a signal. After receiving the signal, the controller 2 will control the motor 501 to drive the lead screw 502 to stop reversing, causing the guide rail frame 4 to stop moving to the right. Then, the controller 2 will control the first electric push rod 1101 to drive the needle 1102 to move to the left, causing the needle 1102 to unlock the mobile phone card tray 101. When the mobile phone card tray 101 is unlocked, the controller 2 will control the first electric push rod 1101 to drive the needle 1102 to move to the right to reset. And as the mobile phone card tray 101 is unlocked, the mobile phone card tray 101 will automatically pop out. Since the locking function of the mobile phone card tray 101 is released, the spring 7 will return to its original state at this time, and the spring 7 will pull the sliding frame 6, the hollow frame 8, and the mobile phone card tray 101 to move to the right. Then, the controller 2 will control the motor 501 to drive the lead screw 502 to continue reversing, causing the guide rail frame 4 to continue moving to the right until the guide rail frame 4 moves back to its original position. After that, the controller 2 will count the detection data after the guide rail frame 4 moves back to its original position and determine that the locking function of the mobile phone card tray 101 is qualified. In this way, the locking function of the mobile phone card tray 101 can be detected once. Then, by repeating the above operations, the locking function of the mobile phone card tray 101 can be detected multiple times; If the guide rail frame 4 can drive the sliding frame 6, the hollow frame 8, and the mobile phone card holder 101 to move rightward and reset through the spring 7, the mobile phone card holder 101 will leave the card slot 301 without being unlocked by the card pin 1102. In this way, after the guide rail frame 4 moves and resets, the controller 2 will stop counting the detection data for this time, take the previous value as the final number, and determine that the locking function of the mobile phone card holder 101 is unqualified. In this way, the locking function of the mobile phone card holder 101 can be completed for detection, and the accurate number of detections can be obtained. Then, the controller 2 controls the heater 9 to briefly heat the hot melt adhesive in the hollow frame 8 to soften the hot melt adhesive (without melting). Subsequently, the controller 2 controls the second electric push rod 1202 to drive the cutting knife 1203 to move upward, so that the cutting knife 1203 cuts off the softened hot melt adhesive, so that the mobile phone card holder 101 that has completed the detection falls on the support table 1 under the influence of gravity. Then, the controller 2 controls the second electric push rod 1202 to drive the cutting knife 1203 to move downward and reset. Finally, the mobile phone card holder 101 that has completed the detection can be taken out from the support table 1.

[0032] See Figure 7 and Figure 8 As shown, it further includes a cooling mechanism. The cooling mechanism includes a pipeline 13, a cooling box 14, a water pump 15, a first water pipe 16, and a second water pipe 17; the pipeline 13 is installed on the left part of the outer side of the hollow frame 8; the cooling box 14 and the water pump 15 are installed on the right side of the guide rail frame 4, the water pump 15 is located behind the cooling box 14, both the cooling box 14 and the water pump 15 are electrically connected to the controller 2, the water inlet of the water pump 15 is communicated with the cooling box 14, the water outlet of the water pump 15 is communicated with one end of the pipeline 13 through the first water pipe 16, and the other end of the pipeline 13 is communicated with the cooling box 14 through the second water pipe 17.

[0033] By setting the cooling mechanism, the coolant can be added into the cooling box 14 during use; when it is necessary to wait for the hot melt adhesive to cool, the controller 2 can control the cooling box 14 and the water pump 15 to be turned on, so that the cooling box 14 cools the coolant, and the water pump 15 pumps the cooled coolant into the pipeline 13 through the first water pipe 16, so that the coolant in the pipeline 13 cools the hot melt adhesive in the hollow frame 8 through heat transfer, so as to accelerate the cooling of the hot melt adhesive and reduce the waiting time of the operator. When the coolant enters the pipeline 13, the coolant in the pipeline 13 will flow back to the cooling box 14 through the second water pipe 17 for recycling. When the hot melt adhesive is completely cooled, the controller 2 controls the cooling box 14 and the water pump 15 to be turned off.

[0034] See Figure 8 As shown, it further includes a shielding film 18; the left end of the shielding film 18 is connected to the support table 1, the right end of the shielding film 18 is connected to the guide rail frame 4, and the shielding film 18 is used to shield the lead screw 502.

[0035] In the initial state, the shielding film 18 is pulled by the guide rail frame 4, so that the shielding film 18 is in a deformed state; By setting the shielding film 18, when the guide rail frame 4 moves to the left, the shielding film 18 will return to its original state. When the guide rail frame 4 moves to the right and resets, the guide rail frame 4 will pull the shielding film 18 to deform. After the cutter 1203 cuts the softened hot melt adhesive, the mobile phone card tray 101 that has completed the detection will fall on the shielding film 18 under the influence of gravity. In this way, it can prevent the mobile phone card tray 101 that has completed the detection from getting stuck on the lead screw 502, and use the shielding film 18 to shield the lead screw 502, and it can also prevent foreign objects from falling on the lead screw 502 and affecting the movement of the guide rail frame 4.

[0036] See Figure 9 and Figure 10 As shown in, it further includes a material changing mechanism. The material changing mechanism includes a loading frame 19, a third electric push rod 20, a tray 21, a baffle 22, a push plate 23, a rotating plate 24, a spring piece 25 and a discharging frame 26; the loading frame 19 is installed on the right side of the top of the support table 1, and the loading frame 19 is used for loading the mobile phone card tray 101; the third electric push rod 20 is installed on the rear side of the top of the support table 1, and the third electric push rod 20 is electrically connected to the controller 2; the tray 21 is slidably arranged on the support table 1, and the tray 21 is connected to the telescopic rod of the third electric push rod 20; the upper part of the rear side of the tray 21 is connected with the baffle 22, and the baffle 22 is used to block the mobile phone card tray 101 in the loading frame 19; the lower part of the front side of the tray 21 is connected with the push plate 23, and the push plate 23 is used to push out the mobile phone card tray 101 that has completed the detection; the rotating plate 24 is rotatably installed on the upper front side of the tray 21; two spring pieces 25 are connected between the front side of the rotating plate 24 and the front side of the tray 21; the discharging frame 26 for discharging the mobile phone card tray 101 is installed on the right part of the front side of the support table 1.

[0037] By setting up a material changing mechanism, during use, an appropriate amount of mobile phone card holders 101 can be stacked in the loading frame 19, and the lowermost mobile phone card holder 101 falls on the tray 21; when it is necessary to make the right end of the mobile phone card holder 101 closely adhere to the left end of the hollow frame 8, the controller 2 can be used to control the third electric push rod 20 to drive the tray 21, the baffle 22, the push plate 23 and the rotating plate 24 to move forward, so that the tray 21 drives the lowermost mobile phone card holder 101 to move forward until the right end of the lowermost mobile phone card holder 101 closely adheres to the left end of the hollow frame 8. At the same time, as the baffle 22 and the push plate 23 move forward, the baffle 22 will block the remaining mobile phone card holders 101 in the loading frame 19, and the push plate 23 will push forward the mobile phone card holder 101 that has completed the detection and fallen on the top of the shielding film 18, so that the mobile phone card holder 101 that has completed the detection slides out from the discharging frame 26. After the right end of the lowermost mobile phone card holder 101 closely adheres to the left end of the hollow frame 8, the right end of the mobile phone card holder 101 is adhered to the left end of the hollow frame 8 with hot melt adhesive to fix the mobile phone card holder 101. Then, the controller 2 is used to control the third electric push rod 20 to drive the tray 21, the baffle 22, the push plate 23 and the rotating plate 24 to move backward and reset. During this period, the rotating plate 24 is blocked by the mobile phone card holder 101, and the mobile phone card holder 101 will squeeze the rotating plate 24 to rotate, and the elastic piece 25 deforms. When the rotating plate 24 is separated from the mobile phone card holder 101, the elastic piece 25 returns to its original state, and the elastic piece 25 drives the rotating plate 24 to reverse and reset. At the same time, as the baffle 22 moves backward and resets, the baffle 22 will release the remaining mobile phone card holders 101 in the loading frame 19, so that the remaining mobile phone card holders 101 in the loading frame 19 fall downward, so that the lowermost mobile phone card holder 101 falls on the tray 21 again. In this way, automatic loading and unloading of the mobile phone card holder 101 to be detected can be realized.
