Description

Technical Field

[0001] The invention belongs to the technical field of automation equipment, and in particular relates to a picture card storage device. Background Art

[0002] The purpose of optical lens design is to focus the incident light beam to an ideal point to form a clear image. However, in practical applications, due to physical limitations and manufacturing errors, the lens cannot perfectly reproduce this ideal state, resulting in various aberrations. These aberrations affect the quality of the image, so they need to be evaluated and controlled through scientific methods.

[0003] Charts are standard test patterns used to evaluate and test camera equipment and related systems. They are usually made on cardboard and are easy to measure and quick to judge. They can effectively improve the clarity and color reproduction of camera output images. In industrial production, especially for products with high quality requirements such as camera lenses, microscopes, telescopes, etc., strict imaging quality control is essential. Chart tests not only provide valuable feedback information for the R&D stage, but also play an indispensable role in mass production and quality inspection.

[0004] In order for manufacturers to use chart tests to ensure that each batch of products meets established standards and can achieve the best performance in terms of consistency and stability, manufacturers generally use multiple types of charts to test products in sequence. In conventional testing equipment, the charts used are mainly replaced manually, resulting in low testing efficiency and high labor costs; in addition, in conventional testing equipment, pictures are generally stacked and stored, so when taking and placing the charts, two adjacent charts will rub against each other, causing damage to the chart graphics, thereby affecting the test accuracy of the product.

[0005] In addition, when loading and unloading the image card, in order to accurately load the specific image card, match the specific image card with the product to be tested and register the information after loading, and put the specific image card back to the specific storage position, a visual system or a barcode scanner is generally set in the test equipment to realize the registration and positioning of the image card after loading and unloading. In conventional automatic testing equipment, a visual recognition system is generally used to scan the image card to obtain the information of the image card. Since the image card itself has various image test patterns and textures, and these patterns and textures are relatively dense and complex, the image card is easy to interfere with the visual recognition system, resulting in the visual recognition system being unable to recognize and obtain the information of the image card, or when recognizing and obtaining the information of the image card, the visual recognition system needs to process a large amount of data, resulting in low efficiency in recognizing and obtaining information, and increased power consumption. Summary of the invention

[0006] The purpose of the present invention is to provide a picture card storage device to solve the technical problems mentioned in the background technology.

[0007] A linear drive assembly, the linear drive assembly comprising a linear motor and a track, the linear motor being transmission-connected to a slide plate sliding on the track; A frame, the frame is mounted on the slide, a plurality of storage units for placing image cards are arranged in the frame, the storage units are used to store image cards, the linear motor is used to drive the slide to drive the frame to move, so that the specific storage unit in the frame moves to align with the entrance of the card taking mechanism, so that the card taking mechanism can take and place the image cards in the storage unit; Each of the image cards is provided with a resistor and at least two signal contacts, and the resistance value of each of the resistors is different, so that each of the image cards obtains a unique number through different resistance values. The signal contact is electrically connected to the resistor, and the signal contact is located on the outer wall of the image card. The storage unit and the card retrieval mechanism are both provided with signal antennae for contacting the signal contacts, so that when the image card is located in the storage unit or the card retrieval mechanism, the storage unit or the card retrieval mechanism can obtain information of different image cards according to different resistance values, and locate different image cards.

[0008] Based on the above technical solution, the present invention achieves the following beneficial effects: 1. The resistance value can be accurately measured to multiple decimal places or the resistance of the resistor can be infinitely increased, that is, the range of resistance selection can be infinite, that is, when the resistance value of the sensing resistor is sensed, the resistance value (digital value) can be displayed as a specific long string of numbers. Therefore, the long string of numbers can be used to label different image cards, thereby realizing information registration of different image cards, and when different image cards are moved to the card retrieval mechanism or each storage unit, each image card can be located; 2. When obtaining the "code" of the image card, the resistance value can be read only when the signal antenna contacts the signal contact point. Therefore, compared with the 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, and reducing the power consumption of the hardware when processing data; 3. Compared with conventional visual recognition systems, the present invention will not be disturbed by various image test patterns and textures on the surface of the picture card itself when acquiring picture card information and positioning the picture card, thereby acquiring picture card information and positioning the picture card more accurately and efficiently.

[0009] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0010] In some embodiments, when optical tests are performed on different products in the optical testing system, the slide is driven by the linear motor to move the frame, so that a specific storage unit in the frame is moved to align with the entrance of the card taking mechanism, thereby taking out the image card in the specific storage unit to the card taking mechanism, so that the card taking mechanism takes the image card to the test space for shooting of a specific device under test, or after the device under test completes the shooting test of a certain image card, the image card in the card taking mechanism is sent to the storage unit for storage, or when a shooting test is performed on a specific device under test, the image card in the card taking mechanism is sent to the storage unit for storage, and the slide is driven by the linear motor to move the frame, so that another specific storage unit in the frame is moved to align with the entrance of the card taking mechanism, so that the card taking mechanism takes out another image card, thereby providing different test environments for manufacturing / replacing the device under test; Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. When the test system tests different devices under test or provides different types of image cards for the devices under test to shoot, the linear motor can drive the slide to drive the frame to move, so that a specific storage unit in the frame moves to align with the entrance of the card taking mechanism, so that the image card in the specific storage unit can be taken out to the card taking mechanism, and the card taking mechanism takes the image card to the test space for shooting of the specific device under test. Therefore, the image card can be replaced through mechanical movement, thereby reducing the high labor cost; 2. According to different devices under test, the specific chart can be supplied to the device under test through the movement of the mechanical mechanism for shooting test, thereby improving the convenience of testing different devices under test and improving the test efficiency; 3. The same device under test can be replaced with different types of charts for photo testing, and different test environments can be created / changed for the device under test, thereby improving the accuracy of the test.

[0011] In some embodiments, a support bar is provided at the bottom end of the storage unit, and support rollers for carrying the picture card are arranged in an array on the support bar. A fixing plate is provided at the top end of the storage unit, and a limiting groove is provided in the middle of the fixing plate for the top end of the picture card to slide into. The two sides of the limiting groove are upper guide rollers for supporting the two sides of the top edge of the picture card, so that the picture card can slide upright onto the support rollers. Based on the above technical solution, since each chart card is independently stored in the corresponding storage unit, and at the same time, the upper guide rollers support both sides of the top edge of the chart card, and the support rollers are used to support the chart card, therefore, when a large number of chart cards are stored in the test system, and when the chart cards are sent into or out of the storage unit, it is possible to effectively avoid the friction between the two chart cards, which may cause damage to the graphics of the chart cards, thereby improving the test accuracy of the product.

[0012] In some embodiments, a feeding and taking material motor is installed on the support bar, and the feeding and taking material motor is drivingly connected to a rotating shaft, and the rotating shaft is drivingly connected to the support roller, so that the support roller can deliver the image card placed on it to the card taking mechanism or transport the image card in the card taking mechanism to the support roller; Based on the above technical solution, the feeding and feeding motor can drive the rotating shaft to drive all the supporting rollers in the storage unit to rotate, thereby realizing the picture card from the supporting rollers on the storage unit into the card retrieval mechanism, and the picture card is extracted from the card retrieval mechanism to the supporting rollers on the storage unit.

[0013] In some embodiments, lower guide rollers for supporting two sides of the bottom edge of the picture card are provided on both sides of the supporting roller; Based on the technical solution, the lower guide rollers are used to support both sides of the bottom edge of the picture card. When the picture card is carried on the support rollers, when the picture card enters the card retrieval mechanism from the support rollers on the storage unit, and when the picture card is extracted from the card retrieval mechanism to the support rollers on the storage unit, the picture card can be placed more stably upright.

[0014] In some embodiments, a buffer pulley is installed at one end of the support bar, and the buffer pulley is used to position the chart card and limit the chart card from sliding out from one end; Based on the above technical solution, after the picture card slides from the card taking mechanism into the support roller on the support bar, the picture card can be prevented from sliding out of one end of the support bar and leaving the storage unit, and the picture card can be allowed to stay at a specific position of the storage unit.

[0015] In some embodiments, the resistor includes a slide rail and a resistance slider, a slider slides on the slide rail, a conductive pulley is mounted on the slider, the conductive pulley contacts the resistance slider and slides on the resistance slider, the conductive pulley 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 pulley and one end of the resistance slider, so as to give the chart card a number; Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. When registering information on each image card, the slider can slide on the slide rail to drive the movable conductive pulley to a certain position of the resistance slider. At this time, the distance between the conductive pulley and one end of the resistance slider also changes. Therefore, the resistance of the resistor is adjusted to a specific value, so as to encode the image card; 2. When there are a large number of graphic cards, and two or more resistors have the same resistance and conflict occurs, the resistance value of the resistor can be adjusted.

[0016] In some embodiments, a magnet is installed on the slider, and the storage unit or the card taking mechanism is provided with a numbering screw module, which is transmission-connected to an adjustment block, and an electromagnet for adsorbing the magnet is installed on the adjustment block, so that when the numbering screw module drives the adjustment block to move, the adjustment block drives the conductive pulley to move to a characteristic position of the resistance slider by adsorbing the magnet through the electromagnet, thereby adjusting the resistance value of the resistor; According to the technical solution, when adjusting the resistance of the resistor, the signal antenna contacts the signal contact to obtain the resistance value of the resistor. Thereafter, by powering on the electromagnet, the electromagnet attracts the magnet. Thereafter, when the numbered lead screw module drives the adjustment block to move, the electromagnet on the adjustment block drives the magnet to move, and the magnet drives the conductive pulley to move to the characteristic position of the resistor slider, thereby adjusting the resistance value of the resistor.

[0017] In some embodiments, when adjusting the resistance value of the resistor, the electromagnet is energized, and thereafter, the numbered lead screw module drives the adjustment block to drive the electromagnet to move from one end of the resistance slider to the other end, so that the electromagnet can absorb the magnets located at different positions of the resistance slider; Based on the above technical solution, the electromagnet can adsorb magnets that stay at different positions on the slide rail, thereby driving the magnets at different positions to move.

[0018] In some embodiments, a clamping finger and a fixing spring are installed on the slider, and the fixing spring pushes the clamping finger to clamp the slide rail so that the slider is fixed at a certain position of the slide rail. The magnet is floatingly arranged on the slider, and when the electromagnet attracts the magnet, the magnet drives the clamping finger to separate from the slide rail so that the slider can slide on the slide rail. Based on the technical solution, the present invention further achieves the following beneficial effects: 1. When the electromagnet does not attract the magnet, that is, when the resistance of the resistor does not need to be adjusted, the fixed spring pushes the clamping finger to clamp the slide rail so that the slider is fixed at a certain position of the slide rail. Therefore, after editing the resistance value of the resistor, it can be prevented that the slider moves with the inertia of the chart card and changes the resistance value; 2. When the electromagnet attracts the magnet and is ready to adjust the position of the slider, since the magnet is floatingly arranged on the slider, when the electromagnet attracts the magnet, the magnet drives the clamping finger to separate from the slide rail, so that the slider can slide on the slide rail.

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clear, this specific implementation method further describes the present invention in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 9As shown, this specific embodiment provides a picture card storage device, which is used in an optical test system, and the optical test system is provided with a card taking mechanism 7 for taking a picture card 8 to a test space for photographing the device under test. The card taking mechanism 7 can be a conventional movable fixture or a device with rollers, conveyor lines or brackets for supporting the picture card 8 to stand upright.

[0024] The image card storage device comprises: A linear drive assembly 1, the linear drive assembly 1 comprises a linear motor 11 and a track 12, the linear motor 11 is transmission-connected to a slide plate 13 sliding on the track 12; The frame 2 is mounted on the slide plate 13. A plurality of storage units 3 for placing the picture cards 8 are arranged in the frame 2. A support bar 31 is arranged at the bottom of the storage unit 3. Support rollers 311 for carrying the picture cards 8 are arranged in a row on the support bar 31. A fixing plate 32 is arranged at the top of the storage unit 3. A limiting groove 321 for the top of the picture card 8 to slide into is arranged in the middle of the fixing plate 32. The two sides of the limiting groove 321 are upper guide rollers 322 for supporting the two sides of the top edge of the picture card 8, so that the picture card 8 can slide upright onto the support rollers 311. When optical tests are performed on different products in the optical testing system, the linear motor 11 can drive the slide 13 to drive the frame 2 to move, so that a specific storage unit 3 in the frame 2 moves to align with the entrance of the card taking mechanism 7, thereby taking out the picture card 8 in the specific storage unit 3 and sending it to the card taking mechanism 7, so that the card taking mechanism 7 can take the picture card 8 to the test space for the specific device under test to shoot, or after the device under test completes the shooting test of a certain picture card 8, the picture card 8 in the card taking mechanism 7 is sent to the storage unit 3 for storage, or when the specific device under test is subjected to a shooting test, the picture card 8 in the card taking mechanism 7 is sent to the storage unit 3 for storage, and the linear motor 11 drives the slide 13 to drive the frame 2 to move, so that another specific storage unit 3 in the frame 2 moves to align with the entrance of the card taking mechanism 7, so that the card taking mechanism 7 can take out another picture card 8, thereby providing different test environments for manufacturing / replacing the device under test.

[0025] When the test system tests different devices under test or provides different types of picture cards 8 for the devices under test to shoot, the linear motor 11 can drive the slide 13 to drive the frame 2 to move, so that the specific storage unit 3 in the frame 2 moves to align with the entrance of the card taking mechanism 7, so that the picture card 8 in the specific storage unit 3 can be taken out to the card taking mechanism 7, and the card taking mechanism 7 can take the picture card 8 to the test space for the specific device under test to shoot. Therefore, the picture card 8 can be replaced by mechanical movement, thereby reducing the high labor cost.

[0026] In addition, according to different devices under test, a specific image card 8 can be supplied to the device under test through the movement of a mechanical mechanism for shooting test, thereby improving the convenience of testing different devices under test and improving the test efficiency; at the same time, the same device under test can be replaced with different types of image cards 8 for photo testing, and different test environments can be created / replaced for the device under test, thereby improving the accuracy of the test.

[0027] Since each image card 8 is independently stored in the corresponding storage unit 3, and at the same time, the upper guide rollers 322 support both sides of the top edge of the image card 8, and the support rollers 311 are used to support the image card 8, when a large number of image cards 8 are stored in the test system, and when the image cards 8 are sent into or out of the storage unit 3, it is possible to effectively avoid the friction between two image cards 8 and cause damage to the graphics of the image cards 8, thereby improving the test accuracy of the product.

[0028] In some embodiments, a feed and take material motor 312 is installed on the support bar 31, and the feed and take material motor 312 is connected to a rotating shaft 313, and the rotating shaft 313 is connected to a support roller 311, so that the support roller 311 can deliver the image card 8 placed on it to the card taking mechanism 7 or transport the image card 8 in the card taking mechanism 7 to the support roller 311.

[0029] The feeding and taking motor 312 drives the rotating shaft 313 to drive all the supporting rollers 311 in the storage unit 3 to rotate, thereby enabling the picture card 8 to enter the card taking mechanism 7 from the supporting rollers 311 on the storage unit 3, and to extract the picture card 8 from the card taking mechanism 7 to the supporting rollers 311 on the storage unit 3.

[0030] In some embodiments, lower guide rollers 314 for supporting two sides of the bottom edge of the picture card 8 are arranged on both sides of the supporting roller 311 .

[0031] The lower guide roller 314 supports both sides of the bottom edge of the picture card 8, so that when the picture card 8 is carried on the supporting roller 311, when the picture card 8 enters the card retrieval mechanism 7 from the supporting roller 311 on the storage unit 3, and when the picture card 8 is extracted from the card retrieval mechanism 7 to the supporting roller 311 on the storage unit 3, the picture card 8 can be placed upright more stably.

[0032] In some embodiments, a buffer pulley 315 is installed at one end of the support bar 31, and the buffer pulley 315 is used to position the chart card 8 and limit the chart card 8 from sliding out from one end.

[0033] After the picture card 8 slides from the card taking mechanism 7 into the support roller 311 on the support bar 31 , the picture card 8 can be prevented from sliding out of one end of the support bar 31 and detaching from the storage unit 3 , and the picture card 8 can be allowed to stay at a specific position of the storage unit 3 .

[0034] Optionally, in some embodiments, each image card 8 is provided with a resistor and at least two signal contacts 33, and the resistance value of each resistor is different, so that each image card 8 obtains a unique number through different resistance values, and the signal contact 33 is electrically connected to the resistor. The signal contact 33 is located on the outer wall of the image card 8, and the storage unit 3 and the card retrieval mechanism 7 are both provided with a signal antenna 6 for contacting the signal contact 33, so that when the image card 8 is located in the storage unit 3 or the card retrieval mechanism 7, the storage unit 3 or the card retrieval mechanism 7 can obtain information of different image cards 8 according to different resistance values, and position different image cards 8.

[0035] By accurately measuring the resistance value to multiple decimal places and being able to infinitely increase the resistance of the resistor, that is, the range of resistor selection can be infinite, that is, when sensing the resistance value of the resistor, the resistance value (digital value) can be displayed as a specific long string of numbers. Therefore, the long string of numbers can be used to label different picture cards 8, thereby realizing information registration of different picture cards 8, and when different picture cards 8 are moved to the card retrieval mechanism 7 or each storage unit 3, each picture card 8 can be positioned. When obtaining the "code" of the picture card 8, the resistance value can be read by only contacting the signal antenna 6 with the signal contact 33. Therefore, compared with traditional visual code scanning and visual positioning, the present invention can simplify the logic of code reading and positioning the picture card 8, thereby improving the efficiency of reading the picture card 8 information and positioning the picture card 8.

[0036] Compared with conventional visual recognition systems, when acquiring information of the picture card 8 and positioning the picture card 8, there will be no interference caused by various image test patterns and textures appearing on the surface of the picture card 8 itself, thereby acquiring information of the picture card 8 and positioning the picture card 8 more accurately and efficiently.

[0037] In some embodiments, the resistor includes a slide rail 41 and a resistor slider 42, a slider 43 slides on the slide rail 41, a conductive pulley 44 is installed on the slider 43, the conductive pulley 44 contacts the resistor slider 42 and slides on the resistor slider 42, the conductive pulley 44 is electrically connected to one of the signal contacts 33, and one end of the resistor slider 42 is electrically connected to the other signal contact 33, so as to adjust to a specific resistance value according to the distance between the conductive pulley 44 and one end of the resistor slider 42, so as to give the chart card 8 a number.

[0038] When registering information for each image card 8, the slider 43 can slide on the slide rail 41 to drive the movable conductive pulley 44 to move to a certain position of the resistance slide bar 42. At this time, the distance between the conductive pulley 44 and one end of the resistance slide bar 42 also changes accordingly, so that the resistance of the resistor is adjusted to a specific value, thereby encoding the image card 8. When there are a large number of image cards 8, when the resistance of two or more resistors is the same and conflicts occur, the resistance value of the resistor can be adjusted.

[0039] In some embodiments, a magnet 45 is installed on the slider 43, and the storage unit 3 or the card retrieval mechanism 7 is provided with a numbered screw module 5, which is transmission-connected to an adjustment block 51, and the numbered screw module 5 is used to drive the adjustment block 51 to move. An electromagnet 52 for adsorbing the magnet 45 is installed on the adjustment block 51, so that when the numbered screw module 5 drives the adjustment block 51 to move, the adjustment block 51 drives the conductive pulley 44 to move to a characteristic position of the resistance slider 42 by adsorbing the magnet 45 through the electromagnet 52, thereby adjusting the resistance value of the resistor.

[0040] When adjusting the resistance of the resistor, the signal antenna 6 contacts the signal contact 33 to obtain the resistance value of the resistor. Thereafter, by powering on the electromagnet 52, the electromagnet 52 attracts the magnet 45. Thereafter, when the numbered lead screw module 5 drives the adjustment block 51 to move, the electromagnet 52 on the adjustment block 51 drives the magnet 45 to move, and the magnet 45 drives the conductive pulley 44 to move to the characteristic position of the resistance slider 42, thereby adjusting the resistance value of the resistor.

[0041] In some embodiments, when adjusting the resistance value of the resistor, the electromagnet 52 is energized, and thereafter, the numbered screw module 5 drives the adjustment block 51 to drive the electromagnet 52 to move from one end of the resistance slider 42 to the other end, so that the electromagnet 52 can adsorb the magnets 45 located at different positions of the resistance slider 42; so that the electromagnet 52 can adsorb the magnets 45 that stay at different positions on the slide rail 41, thereby achieving the ability to drive the magnets 45 at different positions to move.

[0042] In some embodiments, a clamping finger 46 and a fixing spring 47 are installed on the slider 43. The fixing spring 47 pushes the clamping finger 46 to clamp the slide rail 41 so that the slider 43 is fixed at a certain position of the slide rail 41. The magnet 45 is floatingly arranged on the slider 43. When the electromagnet 52 attracts the magnet 45, the magnet 45 drives the clamping finger 46 to separate from the slide rail 41 so that the slider 43 can slide on the slide rail 41.

[0043] When the electromagnet 52 does not attract the magnet 45, that is, when there is no need to adjust the resistance of the resistor, the fixing spring 47 pushes the clamping finger 46 to clamp the slide rail 41 so that the slider 43 is fixed at a certain position of the slide rail 41. Therefore, after editing the resistance value of the resistor, it is possible to prevent the slider 43 from moving with the inertia of the chart 8 and changing the resistance value.

[0044] When the electromagnet 52 attracts the magnet 45 and prepares to adjust the position of the slider 43, since the magnet 45 is floatingly arranged on the slider 43, when the electromagnet 52 attracts the magnet 45, the magnet 45 drives the clamping finger 46 to separate from the slide rail 41, so that the slider 43 can slide on the slide rail 41.

[0045] In order to more clearly illustrate the image card storage device described in this specific implementation, the following embodiments are listed. Example

[0051] When optical testing is performed on different products in the optical testing system, the linear motor 11 drives the slide 13 to move the frame 2 so that the specific storage unit 3 in the frame 2 moves to align with the entrance of the card taking mechanism 7. At this time, the feed motor 312 drives the rotating shaft 313, and the rotating shaft 313 drives all the supporting rollers 311 to rotate, and the image card 8 in the specific storage unit 3 is taken out to the card taking mechanism 7, so that the card taking mechanism 7 takes the image card 8 to the test space for the specific device under test to be photographed.

[0052] After the device under test completes the shooting test of a certain picture card 8 , the picture card 8 in the card taking mechanism 7 is sent to the storage unit 3 for storage.

[0053] When performing a shooting test on a specific device under test, the picture card 8 in the card taking mechanism 7 is sent to the storage unit 3 for storage, and the linear motor 11 drives the slide 13 to drive the frame 2 to move, so that another specific storage unit 3 in the frame 2 moves to align with the entrance of the card taking mechanism 7. At this time, the feed motor 312 drives the rotating shaft 313, and the rotating shaft 313 drives all the supporting rollers 311 to rotate, and the picture card 8 in another specific storage unit 3 is taken out to the card taking mechanism 7, giving the device under test a different test environment for manufacturing / replacement.

[0060] The linear drive assembly 1 comprises a linear motor 11 and a track 12 . The linear motor 11 is transmission-connected to a slide plate 13 which slides on the track 12 .

[0061] The frame 2 is mounted on the slide plate 13 , and a plurality of storage units 3 for placing picture cards 8 are arranged in the frame 2 .

[0063] Each image card 8 is provided with a resistor and at least two signal contacts 33. The resistance value of each resistor is different from each other, so that each image card 8 obtains a unique number through different resistance values. The signal contact 33 is electrically connected to the resistor. The signal contact 33 is located on the outer wall of the image card 8. The storage unit 3 and the card taking mechanism 7 are both provided with a signal feeler 6 for contacting the signal contact 33, so that when the image card 8 is located in the storage unit 3 or the card taking mechanism 7, the storage unit 3 or the card taking mechanism 7 can obtain information of different image cards 8 according to different resistance values, and position different image cards 8. When the resistor is set to a specific resistance, The resistance of the resistors on each chart card 8 can be made different from each other by infinitely being precise to multiple decimal places of the resistance value and by infinitely increasing the resistance of the resistor (that is, the selection range of the resistance can be infinite). When sensing the resistance value of the resistor, the resistance value (digital value) can be displayed as a specific long string of numbers. Therefore, the long string of numbers can be used to label different chart cards 8, thereby realizing information registration for different chart cards 8.

[0064] The resistor includes a slide rail 41 and a resistor slider 42. A slider 43 slides on the slide rail 41. A conductive pulley 44 is installed on the slider 43. The conductive pulley 44 contacts the resistor slider 42 and slides on the resistor slider 42. The conductive pulley 44 is electrically connected to one of the signal contacts 33. One end of the resistor slider 42 is electrically connected to the other signal contact 33, so as to adjust to a specific resistance value according to the distance between the conductive pulley 44 and one end of the resistor slider 42, so as to give the chart 8 a number.

[0065] The slider 43 is provided with a magnet 45, the storage unit 3 or the card taking mechanism 7 is provided with a numbered screw module 5, the numbered screw module 5 is connected to the adjusting block 51 in a transmission manner, the numbered screw module 5 is used to drive the adjusting block 51 to move, and the adjusting block 51 is provided with an electromagnet 52 for adsorbing the magnet 45, so that when the numbered screw module 5 drives the adjusting block 51 to move, the adjusting block 51 drives the electromagnet 52 to adsorb the magnet 45 and drives the conductive pulley 44 to move to a characteristic position of the resistance slide bar 42, thereby adjusting the resistance value of the resistor. The slider 43 is provided with a clamping finger 46 and a fixing spring 47, the fixing spring 47 pushes the clamping finger 46 to clamp the slide rail 41, so that the slider 43 is fixed at a certain position of the slide rail 41, the magnet 45 is floatingly arranged on the slider 43, and when the electromagnet 52 adsorbs the magnet 45, the magnet 45 drives the clamping finger 46 to separate from the slide rail 41, so that the slider 43 can slide on the slide rail 41.

[0066] When optical testing is performed on different products in the optical testing system, the linear motor 11 drives the slide 13 to move the frame 2 so that the specific storage unit 3 in the frame 2 moves to align with the entrance of the card taking mechanism 7. At this time, the feed motor 312 drives the rotating shaft 313, and the rotating shaft 313 drives all the supporting rollers 311 to rotate, and the image card 8 in the specific storage unit 3 is taken out to the card taking mechanism 7, so that the card taking mechanism 7 takes the image card 8 to the test space for the specific device under test to be photographed.

[0067] After the device under test completes the shooting test of a certain picture card 8 , the picture card 8 in the card taking mechanism 7 is sent to the storage unit 3 for storage.

[0068] When performing a shooting test on a specific device under test, the picture card 8 in the card taking mechanism 7 is sent to the storage unit 3 for storage, and the linear motor 11 drives the slide 13 to drive the frame 2 to move, so that another specific storage unit 3 in the frame 2 moves to align with the entrance of the card taking mechanism 7. At this time, the feed motor 312 drives the rotating shaft 313, and the rotating shaft 313 drives all the supporting rollers 311 to rotate, and the picture card 8 in another specific storage unit 3 is taken out to the card taking mechanism 7, giving the device under test a different test environment for manufacturing / replacement.

[0069] When encoding the chart card 8 (i.e., adjusting the resistance value of the resistor of the chart card 8), the signal antenna 6 is contacted with the signal contact 33 in advance to obtain the resistance value of the resistor. Thereafter, the electromagnet 52 is energized, and the numbered screw module 5 drives the adjustment block 51 to drive the electromagnet 52 to move from one end of the resistance slider 42 to the other end, so that the electromagnet 52 can absorb the magnet 45 located at different positions of the resistance slider 42. Thereafter, when the numbered screw module 5 drives the adjustment block 51 to move, the electromagnet 52 on the adjustment block 51 drives the magnet 45 to move, and the magnet 45 drives the conductive pulley 44 to move to the characteristic position of the resistance slider 42, thereby adjusting the resistance value of the resistor.

[0070] When the picture card 8 is moved to a storage unit 3 or a card retrieval mechanism 7, it is necessary to read the number of the picture card 8 to register the information of the picture card 8, obtain the information of the picture card 8, and locate the picture card 8. The resistance value can be read by simply contacting the signal antenna 6 with the signal contact 33. The resistance value (digital value) can be displayed as a specific long string of numbers, thereby obtaining the code of the picture card 8.
