Description

Technical Field

[0001] The present invention belongs to the technical field of testing equipment, and particularly relates to an optical testing equipment for mobile phone lenses. Background Art

[0002] In recent years, mobile phone manufacturers have continuously invested resources in improving lens hardware and technology, such as enabling lenses to have higher pixel counts, larger sensor sizes, more advanced optical image stabilization systems, and configuring multiple lenses in mobile phones, in order to enhance the user's photo-taking experience. Before a mobile phone is produced or when developing mobile phone camera imaging, the lens is generally tested. Conventional lens testing generally involves taking pictures of the lens against a specific test chart and using software algorithms to analyze the taken pictures to determine the lens performance. In order to more accurately obtain the performance of the lens in different scenarios, the lens will take pictures and test against multiple specific test charts.

[0003] In conventional mobile phone lens testing equipment, it is generally through manual operation to replace the test chart so that the mobile phone lens can take pictures of multiple test charts. Therefore, the operator needs to stay by the testing equipment and wait for the lens to finish taking pictures of a certain test chart before being able to take out the test chart and replace it with another one, resulting in high labor costs and low testing efficiency. For the testing equipment, the testing equipment needs to wait for the operator to complete taking out the test chart in the equipment and putting in another test chart before it can continue the testing work. In addition, after the operator completes replacing the test chart, the operator also needs to register the information of the test chart replaced into the testing equipment in the testing software so that the testing software can match the test chart being photographed during photo analysis, resulting in cumbersome operations and low testing efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide an optical testing equipment for mobile phone lenses to solve the technical problems described in the background art.

[0005] An optical testing equipment for mobile phone lenses includes:

[0006] A machine cover, which is used to shield external light interference so as to form a testing environment inside the machine cover;

[0007] A testing station, which is located inside the machine cover. A Nest testing module, a conveying and circulation module, and a backlight module are arranged on the testing station. The Nest testing module is used to set the product to be tested. The conveying and circulation module is used to convey the test chart to the front of the Nest testing module for the product to be tested to take pictures of the test chart for testing. The backlight module is used to illuminate the test chart;

[0008] Storage station. A frame and a linear motor drive module are arranged on the storage module. At least two storage positions are arranged in the frame. The storage positions are used for placing graphic cards. A loading and unloading mechanism is installed on the storage positions. The linear motor drive module is used to drive the frame to drive each storage position to move to align with the conveying and circulation module respectively. The loading and unloading mechanism is used to send the graphic cards in the storage positions to the conveying and circulation module and to recycle the graphic cards on the conveying and circulation module into the storage positions, so that the conveying and circulation module can convey different graphic cards to different products to be tested or take pictures and tests of the same product to be tested.

[0009] Based on the above technical solution, the present invention achieves the following beneficial effects:

[0010] 1. When a product to be tested needs to take a picture test of a specific graphic card, the linear motor drive module drives the frame to drive each storage position to move, so that the storage position where the graphic card is placed moves to align with the conveying and circulation module. After that, the loading and unloading mechanism can convey the graphic card to the conveying and circulation module, so that the conveying and circulation module conveys the graphic card to the front of the Nest test module to give the product to be tested a picture shooting test, thus realizing the loading of the graphic card.

[0011] 2. After the product to be tested completes the picture shooting test of the graphic card on the conveying and circulation module, the loading and unloading mechanism or the conveying and circulation module can recycle the graphic card into the storage position for storage for the next use, thus realizing the unloading of the graphic card and centralized storage management of the graphic cards.

[0012] 3. When the product to be tested needs to continue to take a picture test of another graphic card after completing the picture shooting test of the graphic card on the conveying and circulation module, after the graphic card on the conveying and circulation module is recycled into the storage position for storage, the linear motor drive module can be used to drive the frame to drive each storage position to move again, so that the storage position where another graphic card is placed moves to align with the conveying and circulation module. After that, the loading and unloading mechanism can convey another graphic card to the conveying and circulation module, so that the conveying and circulation module conveys the graphic card to the front of the Nest test module to give the product to be tested a picture shooting test. Therefore, by mechanical movement, the graphic cards can be replaced, so that the mobile phone lens can take pictures of multiple graphic cards, and the operator does not need to wait for the test equipment to replace the graphic cards, thus improving the test efficiency and reducing the labor cost.

[0013] In order to further optimize the above technical solution, without conflict, one or more of the following embodiments can be optionally combined.

[0014] In some embodiments, the conveying and circulation module includes a first chassis and a first top frame. The first chassis is equipped with a first supporting wheel and a first motor. The first supporting wheel is used to carry the graphic card. A first bottom supporting wheel for supporting the graphic card to stand upright on the first supporting wheel is fixedly arranged beside the first supporting wheel. The first motor is used to drive the first supporting wheel to move, so that the first supporting wheel can send the graphic card thereon to the storage position or take out the graphic card from the storage position. The first top frame is equipped with a first top supporting wheel for supporting the graphic card to stand upright on the first supporting wheel.

[0015] Based on the above technical solution, the present invention can achieve the following beneficial effects:

[0016] 1. Since the graphic card is placed on the first supporting wheel and the first motor can drive the first supporting wheel to move, the first supporting wheel can send the graphic card thereon to the storage position or take out the graphic card from the storage position. At the same time, the position between the graphic card and the product to be tested can be adjusted horizontally and parallelly to improve the test accuracy.

[0017] 2. When the product to be tested takes a picture of the graphic card, the product to be tested and the graphic card need to be parallel. Therefore, enabling the graphic card to be set upright for the product to be tested to take pictures can facilitate the installation and disassembly of the product to be tested on the Nest test module and also reduce the height of the test space.

[0018] 3. Through the arrangement of the first bottom supporting wheel and the first top supporting wheel, when the graphic card is vertically supported, it can effectively avoid blocking the shooting line of sight of the graphic card over a large area.

[0019] In some embodiments, the first chassis is provided with a first auxiliary supporting wheel and a first shifting mechanism. The first auxiliary supporting wheel and the first bottom supporting wheel are arranged at intervals. The first auxiliary supporting wheel is used to carry the graphic card. The first top frame is equipped with a first auxiliary top wheel located between adjacent first top supporting wheels. The first auxiliary top wheel is used to laterally support the outer top surface of the graphic card on the first auxiliary supporting wheel, so that the graphic card can stand upright on the first auxiliary supporting wheel. The first shifting mechanism is used to drive the first supporting wheel and the first top supporting wheel to move away between two adjacent first auxiliary supporting wheels, and drive the first top supporting wheel to move up and down away between two adjacent first auxiliary top wheels, so as to push the graphic card away from the first auxiliary supporting wheel through the first bottom supporting wheel and the first top supporting wheel. At this time, the storage position can convey another graphic card to the first auxiliary supporting wheel for the product to be tested to take a test picture. At the same time, the first bottom supporting wheel can send the graphic card thereon back to the storage position. Subsequently, the first shifting mechanism drives the first supporting wheel, the first bottom supporting wheel and the first top supporting wheel to reset and move up and down, so that the first bottom supporting wheel can carry the graphic card on the first auxiliary supporting wheel to prepare for moving another graphic card away from the first auxiliary supporting wheel.

[0020] Based on the above technical solution, the present invention can further achieve the following beneficial effects:

[0021] 1. Before the figure card is sent to the conveying and circulation module at the storage position for taking pictures of the product to be tested, the first shifting mechanism drives the first supporting wheel and the first bottom supporting wheel to move away between two adjacent first auxiliary supporting wheels, and drives the first top supporting wheel to move up and down to move away between two adjacent first auxiliary top wheels, so as to push the figure card in the conveying and circulation module away from the first auxiliary supporting wheel through the first supporting wheel and the first top supporting wheel, making room for the storage position to send in the figure card. After that, the first bottom supporting wheel is driven by the first motor to send the figure card on it back to the storage position where the figure card was just sent out for storage. Therefore, it can solve the problem of idle waste of space after the storage position sends out the figure card;

[0022] 2. After the first bottom supporting wheel sends the figure card on it back to the storage position for storage, the first shifting mechanism drives the first supporting wheel and the first bottom supporting wheel to move back to the position between two adjacent first auxiliary supporting wheels for resetting, and drives the first top supporting wheel to move up and down to move back to the position between two adjacent first auxiliary top wheels for resetting. During the resetting of the first supporting wheel and the first top supporting wheel, the first shifting mechanism drives the first supporting wheel and the first top supporting wheel to open relative to each other, thus avoiding the upper and lower sides of the figure card on the first auxiliary supporting wheel from conflicting with the first supporting wheel and the first top supporting wheel.

[0023] In some embodiments, the testing station is further provided with a circulation height adjustment component, which is used to drive the conveying and circulation module to move up and down to adjust the height of the figure card located in the conveying and circulation module;

[0024] Based on the above technical solutions, the present invention can further achieve the following beneficial effects:

[0025] After the figure card is sent from the storage position to the conveying and circulation module and before the product to be tested takes pictures of the figure card, the circulation height adjustment component can be used to drive the conveying and circulation module to move up and down to adjust the height of the figure card located in the conveying and circulation module. At the same time, the first motor can be used to drive the first supporting wheel to move, thereby driving the figure card to move horizontally, so as to correct the midpoint position between the figure card and the product to be tested and improve the test accuracy.

[0026] In some embodiments, the loading and unloading mechanism includes a second bottom frame and a second top frame. The second bottom frame is installed with a second supporting wheel and a second motor. The second supporting wheel is used to support the figure card. A second bottom supporting wheel for supporting the figure card upright on the second supporting wheel is arranged beside the second supporting wheel. The second motor is used to drive the second supporting wheel to move, so that the second supporting wheel can send the figure card on it to the conveying and circulation module or retrieve the figure card from the conveying and circulation module. The second top frame is installed with a second top supporting wheel for supporting the figure card upright on the second supporting wheel;

[0027] Based on the above technical solutions, the present invention can further achieve the following beneficial effects:

[0028] 1. Since the graphic card is placed on the second supporting roller, and the second motor can drive the second supporting roller to move, it is possible to send the graphic card on the second supporting roller into the conveying and circulation module or retrieve the graphic card from the conveying and circulation module.

[0029] 2. Through the arrangement of the second bottom supporting wheel and the second top supporting wheel, the graphic card can be stored upright in the storage position, which is convenient for vertically feeding the graphic card into the conveying and circulation module and for storing the graphic card retrieved from the conveying and circulation module.

[0030] 3. The graphic card is stored upright in the storage position, which is convenient for the linear motor to drive the frame to align the graphic cards in each storage position with the conveying and circulation module.

[0031] In some embodiments, the second chassis is provided with a second auxiliary supporting roller, a second auxiliary supporting bottom wheel and a second shifting mechanism. The second auxiliary supporting roller and the second auxiliary supporting bottom wheel are arranged at intervals and staggeredly with the second supporting roller. The second auxiliary supporting roller is used to support the graphic card. The second top frame is installed with a second auxiliary top wheel. The second auxiliary top wheel is arranged at intervals and staggeredly with the second top supporting wheel. The second auxiliary top wheel is used to laterally support the outer top surface of the graphic card located on the second auxiliary supporting roller, so that the graphic card can stand upright on the second auxiliary supporting roller. The second shifting mechanism is used to drive the second auxiliary supporting roller and the second auxiliary supporting bottom wheel to move into the space between two adjacent second bottom supporting wheels, and to drive the second auxiliary top wheel to move into the space between two adjacent second top supporting wheels, so that the graphic card located on the second auxiliary supporting roller is transferred to the second supporting roller for the second bottom supporting wheel to send the graphic card into the conveying and circulation module. Subsequently, the second shifting mechanism drives the second auxiliary supporting roller, the second auxiliary supporting bottom wheel and the second auxiliary top wheel to reset and lift. The second auxiliary supporting roller and the second auxiliary supporting bottom wheel move away from the space between two adjacent second bottom supporting wheels, and the second auxiliary top wheel moves away from the space between two adjacent second top supporting wheels, waiting for the conveying and circulation module to send another graphic card to the second auxiliary supporting roller.

[0032] Based on the above technical solutions, the present invention further achieves the following beneficial effects:

[0033] 1. Since the second auxiliary supporting roller is arranged at intervals and staggeredly with the second bottom supporting wheel, the graphic card can be selectively placed on the second auxiliary supporting roller and another graphic card can be placed on the second bottom supporting wheel. After the graphic card on the second supporting roller is sent into the conveying and circulation module, the second shifting mechanism drives the second auxiliary supporting roller and the second auxiliary supporting bottom wheel to move into the space between two adjacent second bottom supporting wheels, and drives the second auxiliary top wheel to move into the space between two adjacent second top supporting wheels, so that the graphic card located on the second auxiliary supporting roller is pushed onto the second supporting roller for the second bottom supporting wheel to send the graphic card into the conveying and circulation module. Therefore, the storage capacity of the graphic cards in each storage position is increased.

[0034] 2. Additionally, optionally, during the period when the second bottom support wheel feeds the graphic card thereon onto the first auxiliary support wheel of the conveying and circulation module, the first bottom support wheel synchronously feeds the graphic card above it onto the second auxiliary support wheel of the storage position. Thereafter, the second shifting mechanism drives the second auxiliary support wheel and the second auxiliary support bottom wheel to move into the space between two adjacent second bottom support wheels, and drives the second auxiliary top wheel to move into the space between two adjacent second top support wheels, so that the graphic card located on the second auxiliary support wheel is transferred to the second support wheel, for the second bottom support wheel to feed the graphic card into the conveying and circulation module. Therefore, when replacing the graphic card in the conveying and circulation module, there is no need to wait for the graphic cards in the conveying and circulation module and the storage position to be taken out before putting in another graphic card, thereby improving the card replacement efficiency. At the same time, when replacing the card, there is no need to additionally set up another storage position to cache the graphic card;

[0035] 3. During the period when the second shifting mechanism drives the second auxiliary support bottom wheel and the second auxiliary top wheel to reset, the second shifting mechanism simultaneously drives the second auxiliary support bottom wheel and the second auxiliary top wheel to open and avoid each other to make way for the upper and lower sides of the graphic card on the second auxiliary support wheel, so as to prevent the second auxiliary support bottom wheel and the second auxiliary top wheel from colliding with the graphic card on the second auxiliary support wheel when resetting.

[0036] In some embodiments, the Nest test module includes a temperature control module, a double linear drive module, a rotary module, and a DUT module. The temperature control module is used to dissipate heat from the Nest test module. The double linear drive module is used to drive the product under test to move, so as to adjust the distance and the center point between the product under test and the graphic card located in the conveying and circulation module. The rotary module is used to drive the product under test to rotate, so as to adjust the inclination between the product under test and the graphic card in the conveying and circulation module. The DUT module is used to obtain the data information of the product under test;

[0037] Based on the above technical solutions, the present invention further achieves the following beneficial effects:

[0038] 1. The setting of the temperature control module can dissipate heat from the entire Nest test module, so as to avoid affecting the test results due to overload and overheating during the test process;

[0039] 2. By driving the product under test to move through the double linear drive module and adjusting the distance and the center point between the product under test and the graphic card located in the conveying and circulation module, the product under test can accurately photograph the graphic card in the conveying and circulation module, improving the test accuracy;

[0040] 3. By driving the product under test to rotate through the rotary module and adjusting the inclination between the product under test and the graphic card in the conveying and circulation module, the product under test can be kept parallel to the graphic card in the conveying and circulation module, thereby improving the accuracy of the photographing test.

[0041] In some embodiments, a backlight moving module, an inclined supplementary light module, and an inclined supplementary rotation module are provided at the test station. The backlight moving module is used to drive the backlight module to move, so as to adjust the distance and the center point between the backlight module and the card located in the conveying and circulation module. The inclined supplementary light module is located on both sides of the Nest test module. The inclined supplementary light module is used to provide supplementary light to the card in the conveying and circulation module. The inclined supplementary rotation module is used to drive the inclined supplementary light module to rotate, so as to adjust the inclination between the inclined supplementary light module and the card in the conveying and circulation module;

[0042] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0043] 1. The backlight moving module drives the backlight module to move, so as to adjust the distance and the center point between the backlight module and the card located in the conveying and circulation module, so that the backlight module can illuminate different cards more evenly;

[0044] 2. The setting of the inclined supplementary light module can enhance, weaken or supply other test ambient light to the photographed surface of the card, so that the product to be tested can photograph and test the card more efficiently;

[0045] 3. The inclined supplementary rotation module drives the inclined supplementary light module to rotate, so as to adjust the inclination between the inclined supplementary light module and the card in the conveying and circulation module, so that the inclined supplementary rotation module can illuminate different cards more evenly.

[0046] In some embodiments, each card is provided with a resistor and at least two signal contacts. The resistance values of each resistor are different from each other, so that each card obtains a unique number through different resistance values. When setting the resistance value of the resistor, the resistor has a resistance value accurate to a specific decimal place or is increased to a resistance value with a specific number of digits, so as to number each card through the resistance value. The signal contacts are electrically connected to the resistor. The signal contacts are located on the outer wall of the card. The storage position and the conveying and circulation module are both provided with signal antennas for contacting the signal contacts, so that when the card is located in the storage position and the conveying and circulation module, the storage position and the conveying and circulation module can obtain information of different cards according to different resistance values, and position different cards, and register the corresponding cards for the product to be tested;

[0047] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0048] 1. 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 reach multiple digits by increasing the resistance. Therefore, by setting resistors with different resistance values on the card, a unique code (resistance value) is given to the card during setting. When sensing the resistance of the resistor on the card, the code of the card is read according to the resistance value (digital value). At this time, the corresponding card can be registered for information, the information can be read, and the position can be located according to this code;

[0049] 2. When obtaining the "code (resistance value)" of the card, only by contacting the signal antenna with the signal contact can the resistance value be read. Therefore, compared with the traditional visual code scanning and visual positioning, the present invention can simplify the logic of reading the code and positioning the card, thereby improving the efficiency of reading the card information and positioning the card.

[0050] 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 the other signal contact to adjust to a specific resistance value according to the distance between the conductive slider and one end of the resistance slider, thereby realizing numbering the card;

[0051] Based on the above technical solutions, the present invention further achieves the following beneficial effects:

[0052] 1. Since the conductive slider can slide on the resistance slider, and at the same time, 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 realizing numbering the card;

[0053] 2. Since the resistance of the resistor can be custom - edited, compared with the resistor with a fixed resistance, when the "numbers" between the cards conflict, the card can be renumbered;

[0054] 3. Since the resistance value of the resistor can be custom - edited, compared with the resistor that produces a single unique resistance, the above - mentioned resistor is more suitable for mass production. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following is described with reference to the accompanying drawings.

[0075] As shown Figures 1 to 18 in the figure, an optical testing device for a mobile phone lens in this specific embodiment includes:

[0076] A hood 1, which is used to shield external light interference so as to form a testing environment inside the hood 1;

[0077] A testing station 2, which is located inside the hood 1. A Nest testing module 21, a conveying and circulation module 3, and a backlight module 22 are arranged on the testing station 2. The Nest testing module 21 is used to set the product to be tested. The conveying and circulation module 3 is used to convey the chart 9 to the front of the Nest testing module 21 for the product to be tested to take a picture test of the chart 9. The backlight module 22 is used to illuminate the chart 9;

[0078] A storage station 5, on which a frame 51 and a linear motor driving module 52 are arranged. At least two storage positions 6 are arranged inside the frame 51. The storage positions 6 are used to place the chart 9. A loading and unloading mechanism is installed on the storage positions 6. The linear motor driving module 52 is used to drive the frame 51 to drive each storage position 6 to move to align with the conveying and circulation module 3 respectively. The loading and unloading mechanism is used to send the chart 9 in the storage position 6 to the conveying and circulation module 3 and to recycle the chart 9 on the conveying and circulation module 3 back into the storage position 6, so that the conveying and circulation module 3 can convey different charts 9 to different products to be tested or take a picture test of the same product to be tested.

[0079] The product to be tested can be products such as mobile phone lenses and cameras. The conveying and circulation module 3 can be a conventional conveying line, conveyor belt, fixture or other modules that can drive the chart 9 to move.

[0080] When the product to be tested needs to take a picture test of a certain specific chart 9, 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 the chart 9 is placed moves to align with the conveying and circulation module 3. After that, the loading and unloading mechanism can send the chart 9 to the conveying and circulation module 3, so that the conveying and circulation module 3 conveys the chart 9 to the front of the Nest testing module 21 for the product to be tested to take a picture test of the chart 9, thereby realizing the loading of the chart 9.

[0081] After the product to be tested completes the picture test of the chart 9 on the conveying and circulation module 3, the loading and unloading mechanism or the conveying and circulation module 3 can recycle the chart 9 into the storage position 6 for storage for the next use, thereby realizing the unloading of the chart 9 and centralized storage management of the chart 9.

[0082] When the product to be tested needs to continue the photographing test on another card 9 after completing the photographing test on the card 9 on the conveying and circulation module 3, after the card 9 on the conveying and circulation module 3 is recycled to the storage position 6 for storage, the linear motor driving module 52 can drive the frame 51 to drive each storage position 6 to move again, so that the storage position 6 where another card 9 is placed moves to align with the conveying and circulation module 3. After that, the loading and unloading mechanism can convey another card 9 to the conveying and circulation module 3 for the conveying and circulation module 3 to convey the card 9 in front of the Nest test module 21 for the product to be tested to perform the photographing test on the card 9. Therefore, the replacement of the card 9 is realized through mechanical movement, enabling the mobile phone lens to take pictures of multiple cards 9, and the operator does not need to wait beside the test equipment to replace the card 9, thus improving the test efficiency and reducing the labor cost.

[0083] In some embodiments, the conveying and circulation module 3 includes a first chassis 31 and a first top frame 32. The first chassis 31 is equipped with a first supporting wheel 311 and a first motor 312. The first supporting wheel 311 is used to support the card 9. A first bottom supporting wheel 313 for supporting the card 9 to stand upright on the first supporting wheel 311 is fixedly arranged beside 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 card 9 thereon to the storage position 6 or take out the card 9 from the storage position 6. The first top frame 32 is equipped with a first top supporting wheel 321 for supporting the card 9 to stand upright on the first supporting wheel 311.

[0084] Since the card 9 is placed on the first supporting wheel 311 and the first motor 312 can drive the first supporting wheel 311 to move, it is possible to send the card 9 on the first supporting wheel 311 to the storage position 6 or take out the card 9 from the storage position 6. At the same time, it is also possible to horizontally and parallelly adjust the position between the card 9 and the product to be tested to improve the test accuracy.

[0085] When the product to be tested takes a picture of the card 9, the product to be tested and the card 9 need to be parallel. Therefore, enabling the card 9 to be erected for the product to be tested to take pictures can facilitate the installation and disassembly of the product to be tested on the Nest test module 21, and at the same time, it can also reduce the height of the test space. In addition, through the settings of the first supporting wheel 311 and the first top supporting wheel 321, when the card 9 is erected and supported, it can effectively avoid blocking the shooting line of sight of the card 9 on a large area.

[0086] Optionally, in some embodiments, the first chassis 31 is provided with a first auxiliary supporting wheel 41 and a first shifting mechanism 42. The first auxiliary supporting wheels 41 are arranged at intervals with the first bottom supporting wheels 313. The first auxiliary supporting wheels 41 are used to support the graphic 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 graphic card 9 located on the first auxiliary supporting wheel 41, so that the graphic card 9 can stand upright on the first auxiliary supporting wheel 41. 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 to drive the first top supporting wheel 321 to move up and down away from between two adjacent first auxiliary top wheels 43, so as to push the graphic 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 convey another graphic card 9 to the first auxiliary supporting wheel 41 for the test product to take a photo test. At the same time, the first bottom supporting wheel 313 can send the graphic card 9 thereon 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 move up and down, so that the first bottom supporting wheel 313 can support the graphic card 9 on the first auxiliary supporting wheel 41, in preparation for moving another graphic card 9 away from the first auxiliary supporting wheel 41.

[0087] The first shifting mechanism 42 can be a cylinder, a lead screw module or other mechanisms that can drive the first bottom supporting wheel 313, the first supporting wheel 311 and the first top supporting wheel 321 to move and lift.

[0088] Before the storage position 6 sends the graphic card 9 into the conveying and circulation module 3 for the test product to take a photo, the first shifting mechanism 42 drives 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 drives the first top supporting wheel 321 to move up and down away from between two adjacent first auxiliary top wheels 43, so as to push the graphic card 9 in the conveying and circulation module 3 away from the first auxiliary supporting wheel 41 through the first supporting wheel 311 and the first top supporting wheel 321, creating space for the storage position 6 to send the graphic card 9 in. After that, the first motor 312 drives the first bottom supporting wheel 313 to send the graphic card 9 thereon back to the storage position 6 that just sent out the graphic card 9 for storage. Therefore, it can solve the problem of idle waste of space after the storage position 6 sends out the graphic card 9.

[0089] After the first bottom support wheel 313 sends the graphic card 9 thereon back 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 and reset between two adjacent first auxiliary supporting wheels 41, and drives the first top support wheel 321 to move up and down and reset between two adjacent first auxiliary top wheels 43. During the resetting 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 wide from each other, so as to avoid the upper and lower sides of the graphic card 9 on the first auxiliary supporting wheel 41 from colliding with the first bottom support wheel 313 and the first top support wheel 321.

[0090] In some embodiments, the testing station 2 is further provided with a circulation height adjustment assembly 33, and the circulation height adjustment assembly 33 is used to drive the conveying and circulation module 3 to lift, so as to adjust the height of the graphic card 9 located in the conveying and circulation module 3.

[0091] The circulation height adjustment assembly 33 can be a cylinder, a lead screw module, a chain module, a robotic arm or other components that can realize the overall lifting of the circulation height adjustment assembly 33.

[0092] After the graphic card 9 is sent from the storage position 6 into the conveying and circulation module 3 and before the product to be tested takes a picture of the graphic card 9, the circulation height adjustment assembly 33 can be used to drive the conveying and circulation module 3 to lift and adjust the height of the graphic card 9 located in the conveying and 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 graphic card 9 to move horizontally, so as to realize the correction of the midpoint position between the graphic card 9 and the product to be tested and improve the test accuracy.

[0093] 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 installed with a second supporting wheel 611 and a second motor 612. The second supporting wheel 611 is used to support the graphic card 9. A second bottom support wheel 613 for supporting the graphic card 9 to stand upright on the second supporting wheel 611 is arranged beside 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 send the graphic card 9 thereon to the conveying and circulation module 3 or retrieve the graphic card 9 from the conveying and circulation module 3. The second top frame 62 is installed with a second top support wheel 621 for supporting the graphic card 9 to stand upright on the second supporting wheel 611.

[0094] Since the graphic card 9 is placed on the second supporting wheel 611 and the second motor 612 can drive the second supporting wheel 611 to move, therefore, it can be realized that the second supporting wheel 611 can send the graphic card 9 thereon into the conveying and circulation module 3 or retrieve the graphic card 9 from the conveying and circulation module 3.

[0095] By providing the second bottom support wheel 613 and the second top support wheel 621, the drawing card 9 can be stored upright in the storage position 6, facilitating the upright feeding of the drawing card 9 into the conveying and circulation module 3 and the storage of the drawing card 9 retrieved from the conveying and circulation module 3. In addition, storing the drawing card 9 upright in the storage position 6 enables the linear motor to drive the frame 51 to align the drawing cards 9 in each storage position 6 with the conveying and circulation module 3.

[0096] Optionally, in some embodiments, the second chassis 61 is provided with a second auxiliary support wheel 71, a second auxiliary support bottom wheel 72, and a second displacement mechanism 73. The second auxiliary support wheel 71 and the second auxiliary support bottom wheel 72 are arranged at intervals and offset from the second support wheel 611. The second auxiliary support wheel 71 is used to support the drawing card 9. The second top frame 62 is installed with a second auxiliary top wheel 74, which is arranged at intervals and offset from the second top support wheel 621. The second auxiliary top wheel 74 is used to laterally support the outer top surface of the drawing card 9 located on the second auxiliary support wheel 71, enabling the drawing card 9 to stand upright on the second auxiliary support wheel 71. The second displacement mechanism 73 is used to drive the second auxiliary support wheel 71 and the second auxiliary support bottom wheel 72 into the space between two adjacent second bottom support wheels 613, and to drive the second auxiliary top wheel 74 into the space between two adjacent second top support wheels 621, so as to transfer the drawing card 9 located on the second auxiliary support wheel 71 to the second support wheel 611 for the second bottom support wheel 613 to feed the drawing card 9 into the conveying and circulation module 3. Subsequently, the second displacement mechanism 73 drives the second auxiliary support wheel 71, the second auxiliary support bottom wheel 72, and the second auxiliary top wheel 74 to reset and lift. The second auxiliary support wheel 71 and the second auxiliary support bottom wheel 72 move away from the space between two adjacent second bottom support wheels 613, and the second auxiliary top wheel 74 moves away from the space between two adjacent second top support wheels 621, waiting for the conveying and circulation module 3 to send another drawing card 9 to the second auxiliary support wheel 71.

[0097] The second displacement mechanism 73 can optionally be a cylinder, a lead screw module, or other mechanisms capable of driving the second auxiliary support wheel 71, the second auxiliary support bottom wheel 72, and the second auxiliary top wheel 74 to move horizontally and lift.

[0098] Since the second auxiliary supporting wheel 71 and the second bottom supporting wheel 613 are arranged at intervals and offset, the card 9 can be selectively placed on the second auxiliary supporting wheel 71 and another card 9 can be placed on the second bottom supporting wheel 613. When the card 9 on the second supporting wheel 611 is sent to the conveying and circulation module 3, the second shifting mechanism 73 drives the second auxiliary supporting wheel 71 and the second auxiliary supporting bottom wheel 72 into the space between two adjacent second bottom supporting wheels 613, and drives the second auxiliary top wheel 74 into the space between two adjacent second top supporting wheels 621, so that the card 9 on the second auxiliary supporting wheel 71 is pushed onto the second supporting wheel 611, and the second bottom supporting wheel 613 sends the card 9 into the conveying and circulation module 3. Therefore, the storage capacity of the card 9 in each storage position 6 is increased.

[0099] In addition, optionally, during the period when the second bottom supporting wheel 613 sends the card 9 thereon to the first auxiliary supporting wheel 41 of the conveying and circulation module 3, the first bottom supporting wheel 313 synchronously sends the card 9 above it to the second auxiliary supporting wheel 71 of the storage position 6. After that, the second shifting mechanism 73 drives the second auxiliary supporting wheel 71 and the second auxiliary supporting bottom wheel 72 into the space between two adjacent second bottom supporting wheels 613, and drives the second auxiliary top wheel 74 into the space between two adjacent second top supporting wheels 621, so that the card 9 on the second auxiliary supporting wheel 71 is transferred to the second supporting wheel 611, and the second bottom supporting wheel 613 sends the card 9 into the conveying and circulation module 3. Therefore, when replacing the card 9 in the conveying and circulation module 3, there is no need to wait for the cards 9 in the conveying and circulation module 3 and the storage position 6 to be taken out before putting in another card 9, thus improving the card replacement efficiency. At the same time, when replacing the card, there is no need to additionally set up another storage position 6 to cache the card 9.

[0100] 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 and avoid each other to give way to the card 9 on the second auxiliary supporting wheel 71, so as to prevent the second auxiliary supporting bottom wheel 72 and the second auxiliary top wheel 74 from colliding with the card 9 on the second auxiliary supporting wheel 71 when resetting.

[0101] In some embodiments, the Nest test module 21 includes a temperature control module 211, a double linear drive module 212, a rotary module 213, and a DUT module 214. The temperature control module 211 is used to dissipate heat from the Nest test module 21. The double linear drive module 212 is used to drive the product under test to move, so as to adjust the distance and the center point between the product under test and the card 9 in the conveying and circulation module 3. The rotary module 213 is used to drive the product under test to rotate, so as to adjust the inclination between the product under test and the card 9 in the conveying and circulation module 3. The DUT module 214 is used to obtain the data information of the product under test.

[0102] The double linear drive module 212 is a module that can drive the product under test to move horizontally and vertically, or horizontally and lift, and its power source can be a cylinder or a lead screw module, etc. The rotary module 213 can drive the product under test to rotate by means of a motor driving a turntable, etc.

[0103] The setting of the temperature control module 211 can dissipate heat from the overall Nest test module 21, so as to avoid affecting the test results due to overload and overheating of the Nest test module 21 during the test process; by driving the product under test to move through the double linear drive module 212 and adjusting the distance and center point between the product under test and the graphic card 9 located in the conveying and circulation module 3, the product under test can accurately photograph the graphic card 9 in the conveying and circulation module 3, improving the test accuracy; by driving the product under test to rotate through the rotary module 213 and adjusting the inclination between the product under test and the graphic card 9 in the conveying and circulation module 3, the product under test can be kept parallel to the graphic card 9 in the conveying and circulation module 3, thereby improving the accuracy of the photographing test.

[0104] In some embodiments, the test station 2 is provided with a backlight moving module 221, an inclined fill light module 23 and an inclined fill light 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 center point between the backlight module 22 and the graphic card 9 located in the conveying and circulation module 3. The inclined fill light module 23 is located on both sides of the Nest test module 21, and the inclined fill light module 23 is used to provide fill light for the graphic card 9 in the conveying and circulation module 3. The inclined fill light rotation module 231 is used to drive the inclined fill light module 23 to rotate, so as to adjust the inclination between the inclined fill light module 23 and the graphic card 9 in the conveying and circulation module 3.

[0105] By driving the backlight module 22 to move through the backlight moving module 221, the distance and center point between the backlight module 22 and the graphic card 9 located in the conveying and circulation module 3 are adjusted, so that the backlight module 22 can illuminate different graphic cards 9 more evenly.

[0106] The setting of the inclined fill light module 23 can enhance, weaken or supply other test ambient light to the photographed surface of the graphic card 9, so that the product under test can photograph and test the graphic card 9 more efficiently; in addition, by driving the inclined fill light module 23 to rotate through the inclined fill light rotation module 231, the inclination between the inclined fill light module 23 and the graphic card 9 in the conveying and circulation module 3 is adjusted, so that the inclined fill light rotation module 231 can illuminate different graphic cards 9 more evenly.

[0107] Optionally, in some embodiments, each card 9 is provided with a resistor 8 and at least two signal contacts 81. The resistance values of each resistor 8 are different from each other, so that each card 9 can obtain a unique number through different resistance values. When setting the resistance value of the resistor 8, the resistor 8 has a resistance value accurate to a specific decimal place or is increased to a resistance value with a specific number of digits, so as to number each card 9 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 card 9. The storage bit 6 and the conveying and circulation module 3 are both provided with signal antennae 84 for contacting the signal contact 81, so that when the card 9 is located in the storage bit 6 and the conveying and circulation module 3, the storage bit 6 and the conveying and circulation module 3 can obtain information of different cards 9 according to different resistance values, and position different cards 9, and register the corresponding card 9 for the product to be tested.

[0108] 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 card 9, a unique code (resistance value) is set for the card 9. When sensing the resistance of the resistor 8 on the card 9, the code of the card 9 is read according to the resistance value (numerical value). At this time, the corresponding card 9 can be registered for information, the information can be read, and the card 9 can be positioned according to this code.

[0109] When obtaining the "code (resistance value)" of the card 9, only the signal antenna 84 needs to contact the signal contact 81 to read the resistance value. Therefore, compared with the traditional visual code scanning and visual positioning, the present invention can simplify the logic of code reading and positioning of the card 9, thereby improving the efficiency of reading information of the card 9 and positioning the card 9.

[0110] Optionally, in some embodiments, the resistor 8 includes a resistance slider 82 and a conductive slider 83. The conductive slider 83 slides on the resistance slider 82. The conductive slider 83 is electrically connected to one of the signal contacts 81. One end of the resistance 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 resistance slider 82, thereby realizing numbering the card 9.

[0111] Since the conductive slider 83 can slide on the resistance slider 82, and at the same time, the distance between the resistance conductive slider 83 and one end of the resistance slider 82 changes, therefore, by adjusting the distance between the conductive slider 83 and one end of the resistance slider 82, the resistance of the resistor 8 can be adjusted, so as to realize numbering the graphics card 9; in addition, since the resistance of the resistor 8 can be custom - edited, compared with the resistor 8 with a fixed resistance, when the "numbers" between the graphics cards 9 conflict, the graphics card 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.

[0124] When the loading and unloading mechanism sends the card 9 at the storage position 6 to the conveying and circulation module 3, the second motor 612 drives the second supporting wheel 611 to move, so that the second supporting wheel 611 can send the card 9 thereon to the first supporting wheel 311 in the conveying and circulation module 3. Subsequently, the first motor 312 drives the first supporting wheel 311 to move, so as to move the card 9 in front of the product to be tested in the Nest testing module 21 and position the card 9.

Thereafter, the loading and unloading mechanism can convey another card 9 to the conveying and circulation module 3 for the conveying and circulation module 3 to convey the card 9 in front of the Nest testing module 21 for the product to be tested to perform the photographing test on the card 9.

[0127] When the conveying and circulation module 3 sends the card 9 back to the storage position 6, the first motor 312 drives the first supporting wheel 311 to move, so as to send the card 9 on the first supporting wheel 311 to the second supporting wheel 611 at the storage position 6.

The second auxiliary supporting wheel 71 is used to support the graphic card 9. The second top frame 62 is provided with a second auxiliary top wheel 74. The second auxiliary top wheel 74 is arranged at intervals and offset with respect to the second top supporting wheel 621. The second auxiliary top wheel 74 is used to laterally support the outer top surface of the graphic card 9 located on the second auxiliary supporting wheel 71, so that the graphic card 9 can stand upright on the second auxiliary supporting wheel 71. 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 the space between two adjacent second bottom supporting wheels 613, and to drive the second auxiliary top wheel 74 to move into the space between two adjacent second top supporting wheels 621, so as to transfer the graphic card 9 located on the second auxiliary supporting wheel 71 to the second supporting wheel 611, and the second bottom supporting wheel 613 sends the graphic card 9 into the conveying and 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. The second auxiliary supporting wheel 71 and the second auxiliary supporting bottom wheel 72 move away from the space between two adjacent second bottom supporting wheels 613, and the second auxiliary top wheel 74 moves away from the space between two adjacent second top supporting wheels 621, waiting for the conveying and circulation module 3 to send another graphic card 9 to the second auxiliary supporting wheel 71. The positional relationship between the second supporting wheel 611, the second bottom supporting wheel 613, the second top supporting wheel 621, the second auxiliary supporting wheel 71, the second auxiliary supporting bottom wheel 72, the second shifting mechanism 73 and the second auxiliary top wheel 74 and the graphic card 9 can be referred to Figure 15 the positional relationship between the first supporting wheel 311, the first bottom supporting wheel 313, the first top supporting wheel 321, the first auxiliary supporting wheel 41 and the first auxiliary top wheel 43 and the graphic card 9 shown in

[0139] The following is the instruction for using a mobile phone lens optical testing device according to this embodiment.

[0140] When the product to be tested needs to continue the photographing test on another graphic card 9 after completing the photographing test on the graphic card 9 on the conveying and circulation module 3, the first shifting mechanism 42 drives the first supporting wheel 311 and the first bottom supporting wheel 313 to move away from the space between two adjacent first auxiliary supporting wheels 41, and drives the first top supporting wheel 321 to lift and move away from the space between two adjacent first auxiliary top wheels 43, so as to push the graphic 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 graphic card 9 is placed moves to align with the conveying and circulation module 3.

[0141] Thereafter, the first motor 312 drives the first bottom support wheel 313 to move, and sends the graphic 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 graphic card 9 on the second support wheel 611 to the first auxiliary support wheel 41 for the product under test to perform a photographing test on the graphic card 9.

[0142] Thereafter, the first shifting mechanism 42 drives the first support wheel 311 and the first bottom support wheel 313 to move back and reset between two adjacent first auxiliary support wheels 41, and drives the first top support wheel 321 to move up and down and reset between two adjacent first auxiliary top wheels 43. During the reset of the first support 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 relative to each other, and the first bottom support wheel 313 and the first top support wheel 321 bypass the upper and lower sides of the graphic card 9 on the first auxiliary support wheel 41; at the same time, the second shifting mechanism 73 drives the second auxiliary support wheel 71 and the second auxiliary support bottom wheel 72 to move into between two adjacent second bottom support wheels 613, and drives the second auxiliary top wheel 74 to move into between two adjacent second top wheels 621. During the reset of the second auxiliary support bottom wheel 72 and the second auxiliary top wheel 74 by the second shifting mechanism 73, the second shifting mechanism 73 simultaneously drives the second auxiliary support bottom wheel 72 and the second auxiliary top wheel 74 to open relative to each other to avoid the upper and lower sides of the graphic card 9 on the second auxiliary support wheel 71.

[0143] The following is Embodiment 3

[0144] As Figure 18 shown, this embodiment provides a mobile phone lens optical test device, which includes all the features of the mobile phone lens optical test device in Embodiment 1 or 2. At the same time, a resistor 8 and at least two signal contacts 81 are provided on each graphic card 9, and the resistance values of each resistor 8 are different from each other, so that each graphic card 9 obtains a unique number through different resistance values. When setting the resistance value of the resistor 8, the resistor 8 uses a resistance value accurate to a specific decimal place or increases to a resistance value with a specific number of digits, so as to number each graphic card 9 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 graphic card 9. The storage position 6 and the conveying and circulation module 3 are both provided with signal antennas 84 for contacting the signal contacts 81, so that when the graphic card 9 is located in the storage position 6 and the conveying and circulation module 3, the storage position 6 and the conveying and circulation module 3 can obtain information of different graphic cards 9 according to different resistance values, and position different graphic cards 9, and register the corresponding graphic card 9 for the product under test.

[0145] The resistor 8 includes a resistive slider 82 and a conductive slider 83. The conductive slider 83 slides on the resistive slider 82. The conductive slider 83 is electrically connected to one of the signal contacts 81, and one end of the resistive 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 resistive slider 82, thereby numbering the graphics card 9.

[0146] Since the resistance value can be accurate to multiple decimal places when testing the resistance value, or the resistance value can reach multiple digits by increasing the resistance when setting the resistance, therefore, by setting the resistor 8 with different resistance values on the graphics card 9, a unique code (resistance value) is set for the graphics card 9. When sensing the resistance of the resistor 8 of the graphics card 9, the code of the graphics card 9 is read according to the resistance value (numerical value). At this time, the corresponding graphics card 9 can be registered for information, read information and located according to this code.

[0147] When adjusting the resistance of the resistor 8 (i.e., re-numbering the graphics card 9), since the conductive slider 83 can slide on the resistive slider 82, and at the same time, the distance between the conductive slider 83 and one end of the resistive slider 82 changes, therefore, the resistance of the resistor 8 can be adjusted by adjusting the distance between the conductive slider 83 and one end of the resistive slider 82, thereby realizing the numbering of the graphics card 9.
