Description

Technical Field

[0001] The present application relates to the technical field of mobile phone case performance testing, and more specifically, to a wireless charging mobile phone case durability testing device; and also to a wireless charging mobile phone case durability testing method. Background Art

[0002] Mobile phone cases are products used to protect or decorate mobile phones. As mobile phones become more and more important in people's lives, the performance of mobile phone cases is becoming more and more important. Especially for wireless charging mobile phone cases, first of all, they are harder than ordinary mobile phone cases used for protection. They are made of PC+TPU material. Compared with ordinary leather or silicone mobile phone cases, they are harder and stronger, and have higher durability requirements. Therefore, a single method of testing cannot meet the quality inspection requirements for wireless charging mobile phone cases; secondly, the concave surface of the wireless charging mobile phone case is embedded with an IM magnet coil. Therefore, when disassembling the mobile phone case, the IM magnet coil embedded in the concave surface of the mobile phone case cannot be separated or have poor functionality.

[0003] There are many indicators for evaluating the performance of mobile phone cases, such as UV weather resistance, abrasion resistance, scratch resistance, stain resistance, durability, etc. Among them, durability is an important test indicator.

[0004] The existing methods for testing the durability of ordinary mobile phone cases include corner bending disassembly and assembly and backward loading disassembly and assembly. After a certain number of cycles of disassembly and assembly, check for defects and make judgments based on the judgment criteria. Figure 1 , Figure 2 As shown, Figure 1 The four corners A, B, C, and D of the mobile phone case 10 are: Figure 2 Schematic diagram of the four corners A1, B1, C1, and D1 of the mobile phone 20, where:

[0005] Corner bending disassembly method: Insert the phone into the phone case 5400 cycles. One cycle includes pressing the B and C corners of the phone case. First, remove the phone case from the B1 corner of the phone and push it. After 2 seconds, put the phone case back in place, then remove the phone case from the C corner and push it back in place after 2 seconds.

[0006] Backward loading and disassembly method: The experimental device was inserted and removed for 1000 cycles. One cycle included insertion and removal. The phone was first inserted at the top edge AD, and then pressed at the bottom edge BC. After that, the B corner of the phone case was removed first, and then the C corner was removed to take out the entire phone.

[0007] For the durability test of ordinary mobile phone cases, in order to ensure the accuracy of the test, manual operation is generally used for testing both inside and outside the industry. The test efficiency is very low and the labor intensity of the testers is high. There are also simple durability testing tools for ordinary mobile phone cases in the existing technology, but they cannot meet the durability test requirements of wireless mobile phone cases, and thus cannot guarantee the accuracy of the test.

[0088] like Figures 3 to 12 As shown, an embodiment of the present invention provides a wireless charging mobile phone case durability testing device, including: a positioning platform 100 provided with a positioning portion 110, the positioning portion 110 is used to accommodate a mobile phone case 10 and position the mobile phone case 10; a test platform 200 for fixing a mobile phone 20; a manipulator 300 that moves the mobile phone case 10 onto the mobile phone 20 by suction and puts the mobile phone case 10 on the mobile phone 20 by pressing; four lifting members 400 corresponding to the four corners 11 of the mobile phone case 10, respectively acting on the four corners 11; wherein the lifting member 400 includes: a vertically arranged lifting cylinder 410, installed on a lifting telescopic rod 411 of the lifting cylinder 410, and acting on a lifting portion 420 of the corner 11.

[0089] The wireless charging mobile phone case durability testing device provided in the embodiment of the present invention first places the mobile phone case 10 on the positioning part 110 for positioning, and then the manipulator 300 adsorbs and moves the mobile phone case 10 to the test platform 200, and places it on the mobile phone 20. Then the manipulator 300 presses the mobile phone case 10 onto the mobile phone 20, and the lifting telescopic rod 411 of the lifting cylinder 410 extends out and acts on the corner 11 of the mobile phone case 10 through the lifting part 420 to push the corner 11 out of the mobile phone 20. Since the manipulator 300 is used to put the mobile phone case 10 on the mobile phone 20, the action of a person putting the mobile phone 20 can be simulated, and the setting of the four lifting parts 400 can be applicable to various existing testing methods. Therefore, compared with the prior art, the wireless charging mobile phone case durability testing device provided by the embodiment of the present invention can test the coating cracking, PC cracking, TPU-PC separation, IM magnet coil separation or poor functionality of the wireless charging mobile phone case, power button / volume button / mute hole / camera hole / large surface damage and other problems of the wireless charging mobile phone case, and the test is accurate.

[0090] In the embodiment of the present invention, a curved portion 421 matching the corner of the mobile phone 20 is provided on the side of the lifting portion 420 corresponding to the mobile phone 20. With this structure, the lifting portion 420 can be made consistent with the corner shape of the mobile phone 20, so that the lifting portion 420 is completely in contact with the corner, long side, and short side of the mobile phone case 10, and the human thumb is more accurately simulated to remove the mobile phone case.

[0091] As a preferred embodiment, in the embodiment of the present invention, a protrusion 422 matching the shape of the arc-shaped portion 421 is provided on the upper surface of the lifting portion 420. The provision of the protrusion 422 makes it possible for the lifting portion 420 to act on the corner 11 not on the upper surface of the lifting portion 420, but on the protrusion 422. In this way, the lifting portion 420 is further in full contact with the corner, long side, and short side of the mobile phone case 10, and the simulated action is closer to the action of a person removing the mobile phone case 10, thereby making the test more accurate.

[0092] The positioning portion 110 in the embodiment of the present invention includes: a positioning enclosure 111 acting on the circumference of the mobile phone case 10; an adjustment position 112 arranged on the positioning enclosure 111; and an adjustment block 113 connected to the positioning enclosure 111 and arranged on the adjustment position 112, the adjustment block 113 having an adjustment state acting on the circumference of the mobile phone case 10.

[0093] When positioning the mobile phone case 10, the mobile phone case 10 is first placed on the positioning portion 110, that is, placed in the area enclosed by the positioning enclosure 111. In actual operation, the area enclosed by the positioning enclosure 111 is larger than the shape of the mobile phone case 10. In order to achieve accurate positioning, an adjustment block 113 is provided. When the mobile phone case 10 is placed on the positioning portion 110, the adjustment block 113 acts on the peripheral surface of the mobile phone case 10, so that the mobile phone case 10 contacts the positioning enclosure 111.

[0094] It should be noted that the positioning enclosure 111 in the embodiment of the present invention can be a positioning column or a positioning block. Preferably, the embodiment of the present invention adopts a continuous positioning block, that is, the area enclosed by the positioning enclosure 111 forms a positioning groove, and the mobile phone case 10 is placed in the positioning groove.

[0095] Specifically, the connection between the adjustment block 113 and the positioning enclosure 111 is that the adjustment block 113 can rotate relative to the positioning enclosure 111 at the adjustment position 112. The preferred connection mode is that a rotating shaft is provided on the positioning enclosure 111, and the adjustment block 113 is connected to the rotating shaft. The rotation of the adjustment block 113 can be driven by a cylinder, or other structures that can rotate the adjustment block 113, such as an oil cylinder, an electric telescopic mechanism, etc.

[0096] The positioning platform 100 in the embodiment of the present invention further includes: a positioning bracket 120 disposed at the bottom of the positioning portion 110 ; and a positioning base plate 130 disposed on an end of the positioning bracket 120 away from the positioning portion 110 .

[0097] The positioning bracket 120 preferably adopts a positioning rod, and the positioning rod is distributed at the bottom of the positioning part 110. The positioning rod can be set to a certain height of the positioning part 110 through the simplest structure, so that the positioning part 110 and the mobile phone 20 on the test platform 200 are in the same plane as much as possible, reducing the range of movement of the manipulator 300, which helps to improve the service life of the manipulator 300. Of course, the positioning bracket 120 can also adopt other structures, such as a columnar or block structure.

[0098] The positioning base plate 130 is provided with mounting holes for mounting with the positioning platform 100 .

[0099] The robot arm 300 in the embodiment of the present invention includes: a six-axis robot arm 310 ; and a suction component 320 and a pressing component 330 disposed on the six-axis robot arm 310 .

[0100] Among them, the six-axis robot arm 310 is a multi-joint, multi-degree-of-freedom robot arm with multiple movements, flexible changes and more "freedom of action". The use of the six-axis robot arm 310 can simulate human arm operation more realistically and control more accurately.

[0101] Among them, the adsorption component 320 is also used to adsorb the mobile phone case 10 when the lifting part 420 lifts the corner 11 of the mobile phone case 10. Such a setting makes the test process closer to the action of people removing the mobile phone case, further improving the accuracy of the durability test of the mobile phone case 10.

[0102] The pressing assembly 330 in the embodiment of the present invention includes: a vertically arranged pressing cylinder 331; and a pressing head 332 arranged on a pressing telescopic rod 3311 of the pressing cylinder 331. When the mobile phone case 10 is placed on the mobile phone 20, the pressing cylinder 331 works, and the pressing telescopic rod 3311 extends downward, so that the pressing head 332 acts on the mobile phone case 10, and the mobile phone case 10 is placed on the mobile phone 20.

[0103] Among them, as a preferred implementation, the pressing head 332 in the embodiment of the present invention adopts a rubber pressing head. Such a configuration can prevent the pressing head 332 from causing damage to the mobile phone case 10 during the test.

[0104] Of course, in order to control the pressure of the pressing head 332, a sensor can be provided to detect the pressure of the pressing head 332 and adjust it.

[0105] The adsorption assembly 320 in the embodiment of the present invention includes: a horizontally arranged adsorption mounting member 321; a first suction cup 322 and a second suction cup 323 vertically mounted on the adsorption mounting member 321. The first suction cup 322 and the second suction cup 323 can act on the same plane. The arrangement of the first suction cup 322 and the second suction cup 323 can ensure the suction force when the mobile phone case 10 is adsorbed from the positioning portion 110, and improve the stability of the mobile phone case 10 during movement. Of course, the suction force of the first suction cup 322 and the second suction cup 323 can be set to be adjustable.

[0106] The manipulator 300 in the embodiment of the present invention further includes: a mounting plate 340 with a suction mounting member 321 mounted on one end and a pressing cylinder 331 mounted on the other end, and the mounting plate 340 is mounted on the six-axis manipulator 310. Such a configuration can ensure the realization of the suction function and the pressing function on the manipulator 300, and can effectively avoid interference between the suction component 320 and the pressing component 330.

[0107] The lifting member 400 in the embodiment of the present invention further includes: a first horizontal moving component 430 and a second horizontal moving component 440, the lifting cylinder 410 is installed on the first slider 431 of the first horizontal moving component 430, and the first horizontal moving component 430 is installed on the second slider 441 of the second horizontal moving component 440, wherein the moving directions of the first slider 431 and the second slider 441 are perpendicular.

[0108] With such an arrangement, each lifting portion 420 has three moving dimensions of XYZ, so that the wireless charging mobile phone case durability testing device provided by the embodiment of the present invention can not only be applicable to various existing testing methods, but also can be applicable to mobile phones of different sizes, and the versatility is further enhanced.

[0109] The first horizontal moving assembly 430 includes: a first moving cylinder 432 arranged horizontally, a first slider 431 installed on a first telescopic rod 433 of the first moving cylinder 432; and a first guide member 434 acting on the first slider 431. With this structure, the lifting member 400 can be more stable during the movement in one horizontal direction (such as the X direction).

[0110] The second horizontal moving assembly 440 includes: a second moving cylinder 442 arranged horizontally, a second slider 441 installed on a second telescopic rod 443 of the second moving cylinder 442; and a second guide member 444 acting on the second slider 441. With this structure, the lifting member 400 can be more stable during the movement in one horizontal direction (such as the Y direction).

[0111] The test platform 200 in the embodiment of the present invention includes: a vertically arranged support column 210 at the top for fixing the mobile phone 20 ; and a base 220 arranged at the bottom of the support column 210 .

[0112] The mobile phone 20 is glued to the top of the support column 210. The setting of the support column 210 can not only keep the mobile phone 20 at a certain height, but also has a simple structure.

[0113] The base 220 is provided with a mounting hole for mounting the test platform 200 .

[0114] The wireless charging mobile phone case durability testing device provided in the embodiment of the present invention further includes: an installation platform 500 , and the positioning platform 100 , the testing platform 200 , the manipulator 300 and the lifting member 400 are all installed on the installation platform 500 .

[0115] The positioning platform 100 is installed on the mounting platform 500 via the positioning base plate 130 ; and the testing platform 200 is installed on the mounting platform 500 via the base 220 .

[0116] The mounting platform 500 preferably adopts a plate-like structure. The setting of the mounting platform 500 can integrate the positioning platform 100, the test platform 200, the manipulator 300 and the lifting component 400 together, so that the structure of the wireless charging mobile phone case durability testing device is more compact and convenient for assembly and transportation.

[0117] The wireless charging mobile phone case durability testing device provided by the embodiment of the present invention further includes: a protective cover 600, and the mounting platform 500 is arranged in the protective cover 600. The setting of the protective cover 600 can prevent dust from entering the wireless charging mobile phone case durability testing device, thereby ensuring the accuracy of the test of the wireless charging mobile phone case durability testing device.

[0144] Conventional mobile phone case disassembly and assembly testing devices and methods, firstly, mostly adopt the method of driving the mobile phone to move to separate the mobile phone from the mobile phone case, because in actual use, when the mobile phone case is removed from the mobile phone, it is inevitable that the mobile phone case will bend and deform, and the existing disassembly and assembly testing device adopts the method of fixing the mobile phone case and moving the mobile phone, and fixes the mobile phone case during the disassembly and assembly process, especially for the wireless charging mobile phone case, the hard PC layer and the TPC layer are stacked and fitted, and the mobile phone case is not bent and deformed, and it is not possible to detect whether the PC layer and the TPC layer are separated, whether the PC layer is cracked, and whether the coating on the side wall of the mobile phone case is cracked. The key coils, chips and other components are arranged in the middle of the mobile phone case, and the middle of the mobile phone case is well positioned, and it is even more impossible to detect defects that may occur in the key parts in the middle, and the present device adopts the method of fixing the mobile phone, through the adsorption component, the pressing component and the four sets of lifting parts, and simulates the method of separating the mobile phone case from the mobile phone in the real scene in the test, so that the mobile phone case is bent and deformed during disassembly and assembly, so that the durability test of the wireless charging mobile phone is rigorous, and the high testing requirements of the smart phone case are met.

[0145] Second, conventional devices can only simulate one disassembly and assembly method, and cannot truly simulate that people may use a variety of different methods to disassemble and assemble mobile phones according to their own habits in actual use, so they cannot detect possible defects. However, this device can flexibly achieve the disassembly of one corner, one side, or four corners by setting four groups of lifting parts that can control their own activities. Through the combination of adsorption components, pressing components and lifting parts on the manipulator, and the automatic control of the rotation and reposition of the adsorption components and pressing components, it can flexibly achieve the adsorption of one corner of the mobile phone case, the disassembly of the other corner and the immediate reassembly, or the installation of one side of the mobile phone case on the mobile phone, or the adsorption of one side of the mobile phone case and the removal of the other side, and other disassembly and assembly methods, thereby improving the accuracy of the durability test of wireless charging mobile phones.

[0146] Third, the device sets up five different testing methods, which include disassembly and assembly methods at different angles and with different strengths in daily life. It conducts durability tests on multiple mobile phone cases from the same batch, so that any mobile phone case may use one of the five testing methods, further improving the accuracy of the test on smart phone cases.

[0147] Among them, S1: 5400 cycles of corner bending and disassembly; S2: 1000 cycles of backward assembly and disassembly; S3: 300 cycles of one corner removal and disassembly; S4: 1000 cycles of right-side assembly and disassembly; S5: 1000 cycles of left-side assembly and disassembly.

[0148] Taking the backward assembly and disassembly in step S2 as an example, the process of testing the durability of the wireless charging mobile phone case by the wireless charging mobile phone case durability testing device provided by the embodiment of the present invention is as follows:

[0149] S21. First, compile the program on the panel PLC controller;

[0150] S22. The tester places the mobile phone case 10 with the concave surface facing downward on the positioning portion 110 on the positioning platform 100, and clamps the mobile phone case 10 by means of the cylinder acting on the adjustment blocks 113 on both sides, so that the mobile phone case 10 is positioned at the center of the positioning portion 110 on the positioning platform 100, and then loosens the adjustment blocks 113 on both sides by means of the cylinder, and removes the mobile phone case 10 by means of the adsorption assembly 320 of the manipulator 300;

[0151] S23. The manipulator 300 moves the mobile phone case 10 to the right side of the mobile phone 20, aligns it with the mute hole, and slides the mobile phone case 10 toward the top of the mobile phone 20;

[0152] S24. The adsorption component 320 of the manipulator 300 breaks the vacuum and rises, the six-axis manipulator 310 rotates, and the pressing head 332 on the pressing component 330 acts on the B corner and the C corner of the mobile phone case 10, and the mobile phone case 10 is loaded into the mobile phone 20;

[0153] S25. After the mobile phone case 10 is loaded, the six-axis robot 310 rotates, the adsorption assembly 320 sucks the mobile phone case 10, and the lifting portion 420 of the lifting member 400 acts on the B corner and the C corner of the mobile phone case 10, respectively, to push the corner 11 of the mobile phone case 10 out of the mobile phone 20;

[0154] S26. The adsorption assembly 320 of the manipulator 300 sucks the mobile phone case 10 and moves in the direction of the angle A and the angle D of the mobile phone case 10 to remove the mobile phone case 10;

[0155] S27. After 1000 cycles from S23 to S26 and then back to S23, the adsorption component 320 of the robot 300 places the mobile phone case 10 on the positioning part 110 on the positioning platform 100 for the inspector to check the appearance.
