Technical Field

[0001] The invention belongs to the technical field of testing equipment, and in particular relates to an optical testing equipment for a mobile phone lens. Background Art

[0002] In recent years, mobile phone manufacturers have continuously invested resources to improve lens hardware and technology, such as making the lens have a higher number of pixels, a larger sensor size, a more advanced optical image stabilization system, and configuring multiple lenses in the phone to enhance the user's photo-taking experience. Before the phone is produced or when developing mobile phone camera imaging, the lens is generally tested. Conventional lens testing generally involves shooting the lens against a specific chart card and using software algorithms to analyze the photos taken to determine the lens performance. In order to more accurately obtain the performance of the lens in different scenarios, the lens will be tested by shooting multiple specific chart cards.

[0003] In conventional mobile phone lens testing equipment, it is common to replace the picture cards manually so that the mobile phone lens can take pictures of multiple picture cards. Therefore, the operator needs to stay with the test equipment and wait for the lens to take a picture of a certain picture card before taking out the picture card and replacing it with another one, which leads to high labor costs and low testing efficiency. For the test equipment, the test equipment needs to wait for manual work to complete the removal of the picture card in the equipment and put in another picture card before continuing the test work. In addition, after the operator completes the replacement of the picture card, he also needs to register the information of the picture card replaced in the test equipment in the test software, so that the test software can match the photographed picture card when analyzing the photo, resulting in cumbersome operation and low testing efficiency.

According to the existing technology, when testing the resistance value, it can be accurate to multiple decimal places, or when setting the resistance, the resistance value can be increased to multiple digits by adding resistance. Therefore, by setting resistors with different resistance values ​​on the chart card, a unique code (resistance value) is given to the chart card. When sensing the resistance of the resistor of the chart card, the code of the chart card is read according to the resistance value (digital value). At this time, the corresponding chart card can be given information registration, information reading and positioning according to the code; 2. When obtaining the "code (resistance value)" of the image card, the resistance value can be read only when the signal antenna contacts the signal contact. Therefore, compared with traditional visual code scanning and visual positioning, the present invention can simplify the logic of code reading and image card positioning, thereby improving the efficiency of reading image card information and positioning the image card.

[0017] In some embodiments, the resistor includes a resistance slider and a conductive slider, the conductive slider slides on the resistance slider, the conductive slider is electrically connected to one of the signal contacts, and one end of the resistance slider is electrically connected to another signal contact, so as to adjust to a specific resistance value according to the distance between the conductive slider and one end of the resistance slider, thereby giving the chart number; Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. Since the conductive slider can slide on the resistance slider, and the distance between the resistance conductive slider and one end of the resistance slider changes, the resistance of the resistor can be adjusted by adjusting the distance between the conductive slider and one end of the resistance slider, thereby giving the chart number; 2. Since the resistance of the resistor can be customized, compared with the resistor with fixed resistance, when the "numbering" between the charts conflicts, the charts can be renumbered; 3. Since the resistance value of the resistor can be custom edited, the above resistor is more suitable for mass production than resistors that produce a single unique resistance.

The Nest test module 21 is used to set the product to be tested, the conveying and circulation module 3 is used to convey the picture card 9 to the front of the Nest test module 21, so that the product to be tested can shoot the picture card 9, and the backlight module 22 is used to illuminate the picture card 9; The storage station 5 has a frame 51 and a linear motor drive module 52 set on the storage module. At least two storage positions 6 are set in the frame 51. The storage position 6 is used to place the image card 9. The loading and unloading mechanism is installed on the storage position 6. The linear motor drive module 52 set is used to drive the frame 51 to drive each storage position 6 to move to align with the conveying circulation module 3. The loading and unloading mechanism is used to send the image card 9 in the storage position 6 to the conveying circulation module 3 and to recover the image card 9 on the conveying circulation module 3 to the storage position 6, so that the conveying circulation module 3 can transport different image cards 9 to different products to be tested or shoot and test the same product to be tested.

[0022] The product to be tested can be a mobile phone lens, a camera, etc. The conveying and circulation module 3 can be a conventional conveying line, a conveying belt, a clamp or other modules that can drive the chart card 9 to move.

[0023] When the product to be tested needs to undergo a photographic test on a specific picture card 9, the linear motor drive module 52 drives the frame 51 to move each storage position 6 so that the storage position 6 where the picture card 9 is placed moves to align with the conveying and circulation module 3. Thereafter, the loading and unloading mechanism can convey the picture card 9 to the conveying and circulation module 3, so that the conveying and circulation module 3 can convey the picture card 9 to the front of the Nest test module 21, and the product to be tested can undergo a photographic test on the picture card 9, thereby realizing the loading of the picture card 9.

[0024] After the product to be tested completes the photographic test of the picture card 9 on the conveying and circulation module 3, the loading and unloading mechanism or the conveying and circulation module 3 can recycle the picture card 9 to the storage position 6 for storage until the next use, thereby realizing the unloading of the picture card 9 and the centralized storage management of the picture card 9.

[0025] After the product to be tested completes the photographing test of the picture card 9 on the conveying and circulation module 3 and needs to continue photographing the test of another picture card 9, the picture card 9 on the conveying and circulation module 3 is recovered and stored in the storage position 6. The linear motor drive module 52 group drive frame 51 can be used to drive each storage position 6 to move again, so that the storage position 6 with another picture card 9 is moved to be aligned with the conveying and circulation module 3. Thereafter, the loading and unloading mechanism can transport another picture card 9 to the conveying and circulation module 3, so that the conveying and circulation module 3 can transport the picture card 9 to the front of the Nest test module 21, so that the product to be tested can be given a photographing test of the picture card 9. Therefore, the picture card 9 is replaced through mechanical movement, so that the mobile phone lens can take pictures of multiple picture cards 9, and the operator does not need to wait for the test equipment to replace the picture card 9, thereby improving the test efficiency and reducing the labor cost.

[0026] In some embodiments, the conveying circulation module 3 includes a first bottom frame 31 and a first top frame 32. The first bottom frame 31 is equipped with a first supporting wheel 311 and a first motor 312. The first supporting wheel 311 is used to support the chart card 9. A first bottom supporting wheel 313 is fixedly arranged next to the first supporting wheel 311 to support the chart card 9 upright on the first supporting wheel 311. The first motor 312 is used to drive the first supporting wheel 311 to move so that the first supporting wheel 311 can send the chart card 9 thereon to the storage position 6 or take the chart card 9 out of the storage position 6. The first top frame 32 is equipped with a first top supporting wheel 321 to support the chart card 9 upright on the first supporting wheel 311.

[0027] Since the chart card 9 is placed on the first supporting wheel 311, and the first motor 312 can drive the first supporting wheel 311 to move, the first supporting wheel 311 can deliver the chart card 9 thereon to the storage position 6 or take the chart card 9 out of the storage position 6. At the same time, the position between the chart card 9 and the product to be tested can be adjusted horizontally and parallelly to improve the test accuracy.

[0028] Because the product to be tested and the picture card 9 need to remain parallel when taking a picture of the picture card 9, the picture card 9 can be set upright to take a picture of the product to be tested, which can facilitate the installation and disassembly of the product to be tested on the Nest test module 21 and also reduce the height of the test space; in addition, by setting the first supporting wheel 311 and the first top supporting wheel 321, when the picture card 9 is supported upright, it can effectively avoid blocking the line of sight of the picture card 9 over a large area.

[0029] In some embodiments, the first bottom frame 31 can be optionally provided with a first auxiliary supporting wheel 41 and a first shifting mechanism 42, the first auxiliary supporting wheel 41 and the first bottom supporting wheel 313 are arranged at intervals, the first auxiliary supporting wheel 41 is used to support the chart card 9, the first top frame 32 is installed with a first auxiliary top wheel 43 located between adjacent first top supporting wheels 321, the first auxiliary top wheel 43 is used to laterally support the outer top surface of the chart card 9 located on the first auxiliary supporting wheel 41, so that the chart card 9 can stand upright on the first auxiliary supporting wheel 41, and the first shifting mechanism 42 is used to drive the first supporting wheel 311 and the first bottom supporting wheel 313 to move away from between two adjacent first auxiliary supporting wheels 41, and drive the first top supporting wheel 321 to move the first auxiliary supporting wheel 311 and the first bottom supporting wheel 313 away from between two adjacent first auxiliary supporting wheels 41. The wheel 321 is lifted and moved away from between the two adjacent first auxiliary top wheels 43, so as to push the picture card 9 away from the first auxiliary supporting wheel 41 through the first supporting wheel 311 and the first top supporting wheel 321. At this time, the storage position 6 can transport another picture card 9 to the first auxiliary supporting wheel 41 for the product to be tested to be photographed and tested. At the same time, the first bottom supporting wheel 313 can send the picture card 9 on it back to the storage position 6. Subsequently, the first shifting mechanism 42 drives the first bottom supporting wheel 313, the first supporting wheel 311 and the first top supporting wheel 321 to reset and lift, so that the first bottom supporting wheel 313 can carry the picture card 9 on the first auxiliary supporting wheel 41, so as to be ready to move another picture card 9 away from the first auxiliary supporting wheel 41.

[0030] The first displacement mechanism 42 may be a cylinder, a screw module or other mechanism capable of driving the first bottom support wheel 313, the first supporting wheel 311 and the first top support wheel 321 to move and rise and fall.

[0031] Before the storage position 6 delivers the picture card 9 into the conveying and circulation module 3 for photographing the product to be tested, the first shifting mechanism 42 drives the first supporting wheel 311 and the first bottom supporting wheel 313 to move away from between the two adjacent first auxiliary supporting wheels 41, and drives the first top supporting wheel 321 to move up and down and away from between the two adjacent first auxiliary top wheels 43, so as to push the picture card 9 in the conveying and circulation module 3 away from the first auxiliary supporting wheel 41 by the first supporting wheel 311 and the first top supporting wheel 321, and make room for the storage position 6 to deliver the picture card 9, and thereafter, the first bottom supporting wheel 313 is driven by the first motor 312 to deliver the picture card 9 on it back to the storage position 6 where the picture card 9 has just been delivered for storage, thereby solving the problem of idle and wasted space after the picture card 9 is delivered by the storage position 6.

[0032] After the first bottom support wheel 313 returns the picture card 9 on it to the storage position 6 for storage, the first shifting mechanism 42 drives the first supporting wheel 311 and the first bottom support wheel 313 to move back to between the two adjacent first auxiliary supporting wheels 41 for reset, and drives the first top support wheel 321 to rise and fall and move back to between the two adjacent first auxiliary top wheels 43 for reset. During the reset of the first supporting wheel 311 and the first top support wheel 321, the first shifting mechanism 42 drives the first bottom support wheel 313 and the first top support wheel 321 to open to each other, thereby avoiding the first bottom support wheel 313 and the first top support wheel 321 from colliding with the upper and lower sides of the picture card 9 on the first auxiliary supporting wheel 41.

[0033] In some embodiments, the test station 2 is further provided with a circulation height adjustment component 33 , and the circulation height adjustment component 33 is used to drive the conveying circulation module 3 to rise and fall, so as to adjust the height of the chart card 9 located in the conveying circulation module 3 .

[0034] The circulation height adjustment component 33 can be a cylinder, a screw module, a chain module, a mechanical arm or other components that can drive the circulation height adjustment component 33 to rise and fall as a whole.

[0035] After the image card 9 is sent from the storage position 6 to the conveying circulation module 3, and before the image card 9 is photographed and tested by the product to be tested, the circulation height adjustment component 33 can be used to drive the conveying circulation module 3 to rise and fall, and adjust the height of the image card 9 located in the conveying circulation module 3. At the same time, the first motor 312 can be used to drive the first supporting wheel 311 to move and drive the image card 9 to move horizontally, thereby realizing the correction of the midpoint position between the image card 9 and the product to be tested, so as to improve the test accuracy.

[0036] In some embodiments, the loading and unloading mechanism includes a second bottom frame 61 and a second top frame 62. The second bottom frame 61 is equipped with a second supporting wheel 611 and a second motor 612. The second supporting wheel 611 is used to support the chart card 9. A second bottom supporting wheel 613 is provided next to the second supporting wheel 611 for supporting the chart card 9 to stand upright on the second supporting wheel 611. The second motor 612 is used to drive the second supporting wheel 611 to move so that the second supporting wheel 611 can deliver the chart card 9 on it to the conveying circulation module 3 or retrieve the chart card 9 from the conveying circulation module 3. The second top frame 62 is equipped with a second top supporting wheel 621 for supporting the chart card 9 to stand upright on the second supporting wheel 611.

[0037] Since the chart card 9 is placed on the second supporting wheel 611 and the second motor 612 can drive the second supporting wheel 611 to move, the second supporting wheel 611 can deliver the chart card 9 thereon to the conveying circulation module 3 or retrieve the chart card 9 from the conveying circulation module 3.

[0038] By setting the second bottom support wheel 613 and the second top support wheel 621, it is possible to store the chart card 9 upright in the storage position 6, so as to facilitate the upright delivery of the chart card 9 into the conveying circulation module 3, and to facilitate the storage of the chart card 9 retrieved from the conveying circulation module 3; in addition, the chart card 9 is stored upright in the storage position 6, which can facilitate the linear motor drive frame 51 to drive the chart card 9 in each storage position 6 to align with the conveying circulation module 3.

[0039] Optionally, in some embodiments, the second bottom frame 61 is provided with a second auxiliary supporting wheel 71, a second auxiliary supporting bottom wheel 72 and a second shifting mechanism 73, the second auxiliary supporting wheel 71 and the second auxiliary supporting bottom wheel 72 are arranged at intervals and staggered with the second supporting wheel 611, the second auxiliary supporting wheel 71 is used to carry the chart card 9, the second top frame 62 is installed with a second auxiliary top wheel 74, the second auxiliary top wheel 74 is arranged at intervals and staggered with the second top supporting wheel 621, the second auxiliary top wheel 74 is used to laterally support the outer top surface of the chart card 9 located on the second auxiliary supporting wheel 71, so that the chart card 9 can stand upright on the second auxiliary supporting wheel 71, and the second shifting mechanism 73 is used to drive the second auxiliary supporting wheel 71 and the second auxiliary supporting bottom wheel 72 to move into an adjacent The second auxiliary supporting wheel 71 is moved between the two second bottom support wheels 613, and the second auxiliary top wheel 74 is driven to move between the two adjacent second top support wheels 621, so that the picture card 9 on the second auxiliary supporting wheel 71 is transferred to the second supporting wheel 611, so that the second bottom support wheel 613 can deliver the picture card 9 to the conveying circulation module 3. Subsequently, the second shifting mechanism 73 drives the second auxiliary supporting wheel 71, the second auxiliary supporting bottom wheel 72 and the second auxiliary top wheel 74 to reset and lift, and the second auxiliary supporting wheel 71 and the second auxiliary supporting bottom wheel 72 move away from between the two adjacent second bottom support wheels 613, and the second auxiliary top wheel 74 moves away from between the two adjacent second top support wheels 621, so as to wait for the conveying circulation module 3 to deliver another picture card 9 to the second auxiliary supporting wheel 71.

[0040] The second shifting mechanism 73 can be selected to be a cylinder, a screw module or other mechanism that can drive the second auxiliary supporting wheel 71, the second auxiliary supporting bottom wheel 72 and the second auxiliary top wheel 74 to move horizontally and rise and fall.

[0041] Since the second auxiliary supporting wheel 71 and the second bottom supporting wheel 613 are arranged at intervals and staggered, it is possible to selectively place a picture card 9 on the second auxiliary supporting wheel 71 and another picture card 9 on the second bottom supporting wheel 613. After the picture card 9 on the second supporting wheel 611 is delivered to the conveying circulation module 3, the second shifting mechanism 73 drives the second auxiliary supporting wheel 71 and the second auxiliary supporting bottom wheel 72 to move between two adjacent second bottom supporting wheels 613, and drives the second auxiliary top wheel 74 to move between two adjacent second top supporting wheels 621, so that the picture card 9 on the second auxiliary supporting wheel 71 is pushed onto the second supporting wheel 611, so that the second bottom supporting wheel 613 can deliver the picture card 9 to the conveying circulation module 3, thereby increasing the storage capacity of picture cards 9 in each storage position 6.

[0042] In addition, it is also possible to choose that while the second bottom support wheel 613 is sending the image card 9 on it to the first auxiliary support wheel 41 of the conveying and circulation module 3, the first bottom support wheel 313 synchronously sends the image card 9 above it to the second auxiliary support wheel 71 of the storage position 6. Thereafter, the second shifting mechanism 73 drives the second auxiliary support wheel 71 and the second auxiliary support bottom wheel 72 to move between the two adjacent second bottom support wheels 613, and drives the second auxiliary top wheel 74 to move between the two adjacent second top support wheels 621, so that the image card 9 located on the second auxiliary support wheel 71 is moved to the second support wheel 611, so that the second bottom support wheel 613 can send the image card 9 to the conveying and circulation module 3. Therefore, when replacing the image card 9 in the conveying and circulation module 3, there is no need to wait for the image card 9 in the conveying and circulation module 3 and the storage position 6 to be taken out before another image card 9 can be put in, thereby improving the card replacement efficiency. At the same time, when changing the card, there is no need to set up an additional storage position 6 to cache the image card 9.

[0043] While the second shifting mechanism 73 drives the second auxiliary supporting bottom wheel 72 and the second auxiliary top wheel 74 to reset, the second shifting mechanism 73 simultaneously drives the second auxiliary supporting bottom wheel 72 and the second auxiliary top wheel 74 to open to each other to avoid the chart card 9 on the second auxiliary supporting wheel 71, so as to avoid the second auxiliary supporting bottom wheel 72 and the second auxiliary top wheel 74 from colliding with the chart card 9 on the second auxiliary supporting wheel 71 when they are reset.

[0044] In some embodiments, the Nest test module 21 includes a temperature control module 211, a dual linear drive module 212, a rotation module 213 and a DUT module 214. The temperature control module 211 is used to dissipate heat for the Nest test module 21. The dual linear drive module 212 is used to drive the product to be tested to move so as to adjust the distance and center point between the product to be tested and the chart card 9 in the conveying and circulation module 3. The rotation module 213 is used to drive the product to be tested to rotate so as to adjust the inclination between the product to be tested and the chart card 9 in the conveying and circulation module 3. The DUT module 214 is used to obtain data information of the product to be tested.

[0045] The dual linear drive module 212 can drive the product to be tested to move horizontally and vertically, or horizontally and vertically, and its power source can be a cylinder or a screw module, etc. The rotary module 213 can drive the product to be tested to rotate by means of a motor driving a turntable, etc.

[0046] The setting of the temperature control module 211 can provide overall heat dissipation for the Nest test module 21, thereby preventing the Nest test module 21 from affecting the test results due to overload and overheating during the test; the dual linear drive module 212 is used to drive the product to be tested to move, and the distance and center point between the product to be tested and the image card 9 in the conveying and circulation module 3 are adjusted, so that the product to be tested can accurately photograph the image card 9 in the conveying and circulation module 3, thereby improving the test accuracy; the rotation module 213 is used to drive the product to be tested to rotate, and the inclination between the product to be tested and the image card 9 in the conveying and circulation module 3 is adjusted, so that the product to be tested can maintain a parallel state with the image card 9 in the conveying and circulation module 3, thereby improving the accuracy of the photo test.

[0047] In some embodiments, the test station 2 is provided with a backlight moving module 221, a diagonal fill light module 23 and a diagonal fill rotation module 231. The backlight moving module 221 is used to drive the backlight module 22 to move so as to adjust the distance and the center point between the backlight module 22 and the picture card 9 located in the conveying circulation module 3. The diagonal fill light module 23 is located on both sides of the Nest test module 21. The diagonal fill light module 23 is used to provide fill light to the picture card 9 in the conveying circulation module 3. The diagonal fill rotation module 231 is used to drive the diagonal fill light module 23 to rotate so as to adjust the inclination between the diagonal fill light module 23 and the picture card 9 in the conveying circulation module 3.

[0048] The backlight moving module 221 drives the backlight module 22 to move, so as to adjust the distance and center point between the backlight module 22 and the image card 9 in the conveying and circulation module 3 , so that the backlight module 22 can illuminate different image cards 9 more evenly.

[0049] The setting of the oblique fill light module 23 can enhance, weaken or supply other test environment light to the photographed surface of the picture card 9, so that the product to be tested can shoot and test the picture card 9 more efficiently; in addition, the oblique fill light module 23 is driven to rotate by the oblique fill rotation module 231 to adjust the inclination between the oblique fill light module 23 and the picture card 9 in the conveying circulation module 3, so that the oblique fill rotation module 231 can provide different picture cards 9 with fill light more evenly.

[0050] Optionally, in some embodiments, each image card 9 is provided with a resistor 8 and at least two signal contacts 81, and the resistance value of each resistor 8 is different from each other, so that each image card 9 obtains a unique number through a different resistance value. When setting the resistance value of the resistor 8, the resistor 8 is accurate to a specific decimal point or is increased to a resistance value with a specific digit, so as to give each image card 9 a number through the resistance value. The signal contact 81 is electrically connected to the resistor 8, and the signal contact 81 is located on the outer wall of the image card 9. The storage position 6 and the conveying circulation module 3 are both provided with a signal antenna 84 for contacting the signal contact 81, so that when the image card 9 is located in the storage position 6 and the conveying circulation module 3, the storage position 6 and the conveying circulation module 3 can obtain information of different image cards 9 according to different resistance values, and locate different image cards 9, and register the image card 9 corresponding to the product to be tested.

[0051] According to the existing electronic circuit technology, when testing the resistance value, it can be accurate to multiple decimal places, or when setting the resistance, the resistance value can reach multiple digits by increasing the resistance. Therefore, by setting resistors 8 with different resistance values ​​on the chart card 9, a unique code (resistance value) is given to the chart card 9. When sensing the resistance of the resistor 8 of the chart card 9, the code of the chart card 9 is read according to the resistance value (digital value). At this time, the corresponding chart card 9 can be given information registration, information reading and positioning according to the code.

[0052] When obtaining the "code (resistance value)" of the image card 9, the resistance value can be read only when the signal antenna 84 contacts the signal contact 81. Therefore, compared with traditional visual code scanning and visual positioning, the present invention can simplify the logic of code reading and positioning of the image card 9, thereby improving the efficiency of reading the image card 9 information and positioning the image card 9.

[0053] Optionally, in some embodiments, the resistor 8 includes a resistor slider 82 and a conductive slider 83, the conductive slider 83 slides on the resistor slider 82, the conductive slider 83 is electrically connected to one of the signal contacts 81, and one end of the resistor slider 82 is electrically connected to the other signal contact 81, so as to adjust to a specific resistance value according to the distance between the conductive slider 83 and one end of the resistor slider 82, thereby achieving numbering of the image card 9.

[0054] Since the conductive slider 83 can slide on the resistor slider 82, and the distance between the conductive slider 83 and one end of the resistor slider 82 changes, the resistance of the resistor 8 can be adjusted by adjusting the distance between the conductive slider 83 and one end of the resistor slider 82, so that the numbering of the graphic card 9 can be achieved; in addition, since the resistance of the resistor 8 can be custom edited, compared with the resistor 8 with fixed resistance, when the "numbering" between the graphic cards 9 conflicts, the graphic cards 9 can be renumbered; at the same time, since the resistance value of the resistor 8 can be custom edited, compared with the resistor 8 that produces a single unique resistance, the above-mentioned resistor 8 is more suitable for mass production.

[0080] The following is a description of the use of a mobile phone lens optical testing device described in this embodiment.

[0081] After the product to be tested completes the photographic test of the image card 9 on the conveying and circulation module 3 and needs to continue photographing the other image card 9, the first shifting mechanism 42 drives the first supporting wheel 311 and the first bottom supporting wheel 313 to move away from between the two adjacent first auxiliary supporting wheels 41, and drives the first top supporting wheel 321 to rise and fall to move away from between the two adjacent first auxiliary top wheels 43, so as to push the image card 9 in the conveying and circulation module 3 away from the first auxiliary supporting wheel 41 through the first bottom supporting wheel 313 and the first top supporting wheel 321; at the same time, the linear motor driving module 52 drives the frame 51 to drive each storage position 6 to move, so that the storage position 6 where another image card 9 is placed is moved to be aligned with the conveying and circulation module 3.

[0082] Thereafter, the first motor 312 drives the first bottom support wheel 313 to move, and sends the picture card 9 on the first bottom support wheel 313 to the second auxiliary support wheel 71; at the same time, the second motor 612 drives the second support wheel 611 to move, and synchronously sends another picture card 9 on the second support wheel 611 to the first auxiliary support wheel 41, so that the product to be tested can be tested by shooting the picture card 9.

[0083] Afterwards, the first shifting mechanism 42 drives the first supporting wheel 311 and the first bottom supporting wheel 313 to move back to between the two adjacent first auxiliary supporting wheels 41 for reset, and drives the first top supporting wheel 321 to move up and down and move back to between the two adjacent first auxiliary top wheels 43 for reset. During the reset of the first supporting wheel 311 and the first top supporting wheel 321, the first shifting mechanism 42 drives the first bottom supporting wheel 313 and the first top supporting wheel 321 to open to each other, and the first bottom supporting wheel 313 and the first top supporting wheel 321 bypass the chart card 9 on the first auxiliary supporting wheel 41. at the same time, the second shifting mechanism 73 drives the second auxiliary supporting wheel 71 and the second auxiliary supporting bottom wheel 72 to move between the two adjacent second bottom supporting wheels 613, and drives the second auxiliary top wheel 74 to move between the two adjacent second top supporting wheels 621. During the period when the second shifting mechanism 73 drives the second auxiliary supporting bottom wheel 72 and the second auxiliary top wheel 74 to reset, the second shifting mechanism 73 simultaneously drives the second auxiliary supporting bottom wheel 72 and the second auxiliary top wheel 74 to open each other to avoid the upper and lower sides of the chart card 9 on the second auxiliary supporting wheel 71.

[0084] The following is Example 3 like Fig.18 As shown, the present embodiment provides a mobile phone lens optical testing device, which includes all the features of the mobile phone lens optical testing device of embodiment 1 or 2, and at the same time, each picture card 9 is provided with a resistor 8 and at least two signal contacts 81, the resistance value of each resistor 8 is different from each other, so that each picture card 9 obtains a unique number through a different resistance value, and when setting the resistance value of the resistor 8, the resistor 8 is accurate to a specific decimal point of resistance or is increased to a resistance value with a specific digit, so as to give each picture card 9 a number through the resistance value, the signal contact 81 is electrically connected to the resistor 8, the signal contact 81 is located on the outer wall of the picture card 9, the storage position 6 and the conveying circulation module 3 are both provided with a signal antenna 84 for contacting the signal contact 81, so that when the picture card 9 is located in the storage position 6 and the conveying circulation module 3, the storage position 6 and the conveying circulation module 3 can obtain information of different picture cards 9 according to different resistance values, and locate different picture cards 9, and register the picture card 9 corresponding to the product to be tested.

[0085] The resistor 8 includes a resistor slider 82 and a conductive slider 83. The conductive slider 83 slides on the resistor slider 82. The conductive slider 83 is electrically connected to one of the signal contacts 81. One end of the resistor slider 82 is electrically connected to the other signal contact 81 to adjust to a specific resistance value according to the distance between the conductive slider 83 and one end of the resistor slider 82, thereby giving the chart 9 a number.

[0086] Since the resistance value can be tested accurately to multiple decimal places, or the resistance value can be increased to multiple digits when setting the resistance, resistors 8 with different resistance values ​​are set on the chart card 9, and a unique code (resistance value) is set on the chart card 9. When sensing the resistance of the resistor 8 of the chart card 9, the code of the chart card 9 is read according to the resistance value (digital value). At this time, information registration, information reading and positioning can be performed on the corresponding chart card 9 according to the code.

[0087] When adjusting the resistance of the resistor 8 (i.e., renumbering the chart card 9), since the conductive slider 83 can slide on the resistor slider 82, and at the same time, the distance between the conductive slider 83 and one end of the resistor slider 82 changes, the resistance of the resistor 8 can be adjusted by adjusting the distance between the conductive slider 83 and one end of the resistor slider 82, thereby achieving renumbering of the chart card 9.
