Description

Technical Field

[0001] The present invention belongs to the technical field of automated equipment, and particularly relates to a graphic card storage device. Background Art

[0002] The design purpose of an optical lens is to focus the incident light beam onto 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 image quality, so scientific methods are needed to evaluate and control them.

[0003] Graphic cards are standard test patterns used to evaluate and test imaging devices and related systems. They are usually made on cardboard and have the characteristics of convenient measurement and quick judgment, and can effectively improve the clarity and color reproduction of the output image quality of cameras. In industrial production, especially for products with high quality requirements such as camera lenses, microscopes, telescopes, etc., strict imaging quality control is crucial. Graphic card testing not only provides valuable feedback information in the R & D stage, but also plays an indispensable role in mass production and quality inspection processes.

[0004] In order for manufacturers to use graphic card testing to ensure that each batch of products meets the established standards and can achieve the best performance in terms of consistency and stability, manufacturers generally use various types of graphic cards to test the products sequentially. In conventional testing equipment, it mainly relies on manual replacement of the used graphic cards, so the testing efficiency is low and the labor cost is high. In addition, in conventional testing equipment, the pictures are generally stacked and stored. Therefore, when taking and placing the graphic cards, the adjacent two graphic cards will rub against each other, resulting in damage to the graphics of the graphic cards, thus affecting the testing accuracy of the products.

[0005] In addition, when loading and unloading the graphic cards, in order to accurately load a specific graphic card, register information with the product to be tested after loading, and unload the specific graphic card and put it back into a specific storage location, a vision system or a barcode scanner is generally set in the testing equipment to achieve registration and positioning of the graphic card after loading and unloading. In conventional automatic equipment, a vision recognition system is generally used to scan the graphic card to obtain the information of the graphic card. Since each graphic card has various image test patterns and textures on its surface, and these patterns and textures are relatively dense and complex, the graphic card is likely to interfere with the vision recognition system, resulting in the vision recognition system being unable to recognize and obtain the information of the graphic card, or when recognizing and obtaining the information of the graphic card, the vision recognition system needs to process a large amount of data, resulting in low efficiency of recognizing and obtaining information and increased power consumption. Summary of the Invention

[0006] The object of the present invention is to provide a picture card storage device to solve the technical problems described in the background art.

[0007] A linear drive assembly, the linear drive assembly includes a linear motor and a track, and the linear motor is drivingly connected to a slide plate that slides on the track;

[0008] A frame, the frame is mounted on the slide plate, and a plurality of storage units for placing picture cards are arranged in the frame. The storage units are used for storing picture cards. The linear motor is used to drive the slide plate 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, for the card taking mechanism to take and place the picture cards in the storage unit;

[0009] Each picture 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 picture card can obtain a unique number through different resistance values. The signal contacts are electrically connected to the resistor. The signal contacts are located on the outer wall of the picture card. Both the storage unit and the card taking mechanism are provided with signal antennae for contacting the signal contacts, so that when the picture card is located in the storage unit or the card taking mechanism, the storage unit or the card taking mechanism can obtain information of different picture cards according to different resistance values, and position different picture cards.

[0010] Based on the above technical solutions, the present invention can achieve the following beneficial effects:

[0011] 1. It is possible to accurately reach multiple decimal places of the resistance value or to infinitely increase the resistance of the resistor. That is, the selection range of the resistance can be infinite. That is, when sensing the resistance value of the resistor, the display of the resistance value (numerical value) can be a specific long string of numbers. Therefore, using this long string of numbers can be used to label different picture cards, so as to realize information registration of different picture cards, and when different picture cards move to the card taking mechanism or each storage unit, each picture card can be positioned;

[0012] 2. When obtaining the "encoding" of the picture card, only need the signal antenna to contact the signal contact to read the resistance value. 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 picture card, thereby improving the efficiency of reading the picture card information and positioning the picture card, and reducing the power consumption when the hardware processes data;

[0013] 3. Compared with the conventional visual recognition system, when the present invention obtains the picture card information and positions the picture card, it will not be interfered by various image test patterns and textures displayed on the surface of the picture card itself, so as to obtain the picture card information and position the picture card more accurately and efficiently.

[0014] To further optimize the above technical solution, without conflict, it can be optionally combined with one or more of the following embodiments.

[0015] In some embodiments, when performing optical tests on different products in the optical test system, the linear motor is used to drive the slide plate 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, thereby realizing taking out the graphic card in the specific storage unit to the card taking mechanism for the card taking mechanism to take the graphic card to the test space for a specific device under test to take pictures. Or after the device under test completes the shooting test of a certain graphic card, the graphic card in the card taking mechanism is sent to the storage unit for storage. Or when performing a shooting test on a specific device under test, the graphic card in the card taking mechanism is sent to the storage unit for storage, and the linear motor is used to drive the slide plate to drive the frame to move, so that another specific storage unit in the frame moves to align with the entrance of the card taking mechanism for the card taking mechanism to take out another graphic card, thereby providing different test environments for manufacturing / replacing the device under test;

[0016] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0017] 1. When the test system tests different devices under test or supplies different types of graphic cards for the device under test to take pictures, the linear motor can be used to drive the slide plate 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, thereby realizing taking out the graphic card in the specific storage unit to the card taking mechanism for the card taking mechanism to take the graphic card to the test space for a specific device under test to take pictures. Therefore, replacing graphic cards is realized through mechanical movement, thereby reducing the high labor cost;

[0018] 2. According to different devices under test, specific graphic cards can be supplied to the device under test for shooting tests through the movement of the mechanical mechanism, thereby improving the convenience of testing different devices under test and improving the test efficiency;

[0019] 3. The same device under test can be replaced with different types of graphic cards for taking pictures and testing, providing different test environments for manufacturing / replacing the device under test, thereby improving the test accuracy.

[0020] In some embodiments, a support bar is provided at the bottom end of the storage unit, and support rollers for supporting the graphic card are arranged on the support bar in a row. A fixing plate is provided at the top end of the storage unit, and a limiting groove for the top end of the graphic card to slide in is provided in the middle of the fixing plate. Upper guide rollers for supporting both sides of the top edge of the graphic card are provided on both sides of the limiting groove, so that the graphic card can slide vertically onto the support rollers;

[0021] 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.

[0022] 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;

[0023] 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.

[0024] 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;

[0025] 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.

[0026] 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;

[0027] 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.

[0028] 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;

[0029] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0030] 1. When registering information for each card, the slider can slide on the slide rail to drive the moving conductive pulley to move to a certain position on the resistance slide bar. At this time, the distance between the conductive pulley and one end of the resistance slide bar also changes. Therefore, the resistance of the resistor is adjusted to a specific value to encode the card.

[0031] 2. When there are a large number of cards and a conflict occurs when the resistances of two or more resistors are the same, the resistance value of the resistor can be adjusted.

[0032] In some embodiments, a magnet is installed on the slider, and a numbered lead screw module is provided in the storage unit or the card taking mechanism. The numbered lead screw module is drivingly connected to an adjustment block, and an electromagnet for adsorbing the magnet is installed on the adjustment block. When the numbered lead screw module drives the adjustment block to move, the adjustment block drives the conductive pulley to move to a specific position on the resistance slide bar by adsorbing the magnet through the electromagnet, thereby adjusting the resistance value of the resistor.

[0033] According to the above 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 energizing the electromagnet to make the electromagnet adsorb the magnet, 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 a specific position on the resistance slide bar, thereby realizing the adjustment of the resistance value of the resistor.

[0034] In some embodiments, when adjusting the resistance value of the resistor, the electromagnet is energized. Thereafter, the numbered lead screw module drives the adjustment block to drive the electromagnet to move from one end of the resistance slide bar to the other end, so that the electromagnet can adsorb the magnets at different positions on the resistance slide bar.

[0035] Based on the above technical solution, the electromagnet can adsorb the magnets staying at different positions on the slide rail, thereby realizing the ability to drive the magnets at different positions to move.

[0036] In some embodiments, a finger clip and a fixing spring are installed on the slider. The fixing spring pushes the finger clip to clamp the slide rail so that the slider is fixed at a certain position on the slide rail. The magnet is floatingly arranged on the slider. When the electromagnet adsorbs the magnet, the magnet drives the finger clip to separate from the slide rail so that the slider can slide on the slide rail.

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

[0038] 1. When the electromagnet does not adsorb the magnet, that is, when the resistance of the resistor does not need to be adjusted, the fixing spring pushes the finger clip to clamp the slide rail so that the slider is fixed at a certain position on the slide rail. Therefore, after editing the resistance value of the resistor, it can be avoided that the slider moves due to the inertia of the card movement and changes the resistance value.

[0039] 2. When the electromagnet adsorbs the magnet and prepares to adjust the position of the slider, since the magnet is floatingly arranged on the slider, when the electromagnet adsorbs the magnet, the magnet drives the clamping finger to separate from the slide rail so that the slider can slide on the slide rail.

[0052] To make the objectives, technical solutions, and advantages of the present invention more clear and understandable, the following provides a further detailed description of the present invention with reference to the accompanying drawings.

[0053] As Figures 1 to 9 shown, this specific embodiment provides a card storage device, which is applied to an optical test system. The optical test system is provided with a card taking mechanism 7 for taking a card 8 to a test space for a device under test to photograph. The card taking mechanism 7 can be a conventional movable fixture or a roller, conveyor line, or bracket for supporting the card 8 to stand upright.

[0054] The card storage device includes:

[0055] A linear drive assembly 1, which includes a linear motor 11 and a track 12. The linear motor 11 is drivingly connected to a slide plate 13 that slides on the track 12;

[0056] A frame 2, which is installed on the slide plate 13. A plurality of storage units 3 for placing the card 8 are arranged inside the frame 2. A support bar 31 is provided at the bottom end of the storage unit 3. Support rollers 311 for supporting the card 8 are arranged in a row on the support bar 31. A fixing plate 32 is provided at the top end of the storage unit 3. A limiting groove 321 for the top end of the card 8 to slide into is provided in the middle of the fixing plate 32. Upper guide rollers 322 for supporting both sides of the top edge of the card 8 are provided on both sides of the limiting groove 321, so that the card 8 can slide upright onto the support rollers 311;

[0057] When performing optical tests on different products in the optical test system, the linear motor 11 can be used to drive the slide plate 13 to drive the frame 2 to move, so that a specific storage unit 3 inside the frame 2 moves to align with the entrance of the card taking mechanism 7, thereby realizing taking out the card 8 in the specific storage unit 3 to the card taking mechanism 7 for the card taking mechanism 7 to take the card 8 to the test space for a specific device under test to photograph. Or after the device under test completes the photographing test of a certain card 8, the card 8 in the card taking mechanism 7 is sent to the storage unit 3 for storage. Or when performing a photographing test on a specific device under test, the card 8 in the card taking mechanism 7 is sent to the storage unit 3 for storage, and the linear motor 11 is used to drive the slide plate 13 to drive the frame 2 to move, so that another specific storage unit 3 inside the frame 2 moves to align with the entrance of the card taking mechanism 7 for the card taking mechanism 7 to take out another card 8, thereby providing different test environments for the device under test for manufacturing / replacing.

[0058] When the test system tests different devices under test or supplies the device under test to photograph different types of test cards 8, the linear motor 11 can drive the slide plate 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, so that the test 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 test card 8 to the test space for a specific device under test to photograph. Therefore, the replacement of the test card 8 is realized through mechanical movement, thereby reducing the high labor cost.

[0059] In addition, according to different devices under test, a specific test card 8 can be supplied to the device under test for photographing and testing through the movement of the mechanical mechanism, 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 test cards 8 for photographing and testing, and different test environments can be created / replaced for the device under test, thereby improving the test accuracy.

[0060] Since each test card 8 is independently stored in the corresponding storage unit 3, and at the same time, the top edges of both sides of the test card 8 are supported by the upper guiding rollers 322, and the test card 8 is carried by the supporting rollers 311, when a large number of test cards 8 are stored in the test system and the test cards 8 are sent into or out of the storage unit 3, the mutual friction of the two test cards 8 can be effectively avoided, so as to prevent the pattern of the test card 8 from being damaged, and the test accuracy of the product is improved.

[0061] In some embodiments, a feeding motor 312 is installed on the support bar 31. The feeding motor 312 is drivingly connected to a rotating shaft 313, and the rotating shaft 313 is drivingly connected to the supporting roller 311, so that the supporting roller 311 can send the test card 8 placed above it to the card taking mechanism 7 or transport the test card 8 in the card taking mechanism 7 to the supporting roller 311.

[0062] By driving the rotating shaft 313 by the feeding motor 312 to drive the test card 8 to rotate on all the supporting rollers 311 in the storage unit 3, the test card 8 can be taken from the supporting roller 311 on the storage unit 3 into the card taking mechanism 7 and the test card 8 can be extracted from the card taking mechanism 7 to the supporting roller 311 on the storage unit 3.

[0063] In some embodiments, lower guiding rollers 314 for supporting both sides of the bottom edge of the test card 8 are arranged on both sides of the supporting roller 311.

[0064] By supporting both sides of the bottom edge of the test card 8 with the lower guiding rollers 314, when the test card 8 is carried on the supporting roller 311, when the test card 8 enters the card taking mechanism 7 from the supporting roller 311 on the storage unit 3, and when the test card 8 is extracted from the card taking mechanism 7 to the supporting roller 311 on the storage unit 3, the test card 8 can be placed more stably and upright.

[0065] 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.

[0066] 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 .

[0067] 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.

[0068] 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.

[0069] Compared with conventional visual recognition systems, when acquiring information of the picture card 8 and positioning the picture card 8, it will not be disturbed by various image test patterns and textures 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.

[0070] In some embodiments, the resistor includes a slide rail 41 and a resistive slider 42. A slider 43 slides on the slide rail 41. A conductive pulley 44 is mounted on the slider 43. The conductive pulley 44 contacts the resistive slider 42 and slides on the resistive slider 42. The conductive pulley 44 is electrically connected to one of the signal contacts 33, and one end of the resistive 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 resistive slider 42, achieving numbering the graphics card 8.

[0071] When registering information for each graphics card 8, the slider 43 can slide on the slide rail 41 to drive the moving conductive pulley 44 to move to a certain position on the resistive slider 42. At this time, the distance between the conductive pulley 44 and one end of the resistive slider 42 also changes accordingly. Therefore, the resistance of the resistor is adjusted to a specific value, thereby encoding the graphics card 8. When there are a large number of graphics cards 8 and a conflict occurs when the resistances of two or more resistors are the same, the resistance value of the resistor can be adjusted.

[0072] In some embodiments, a magnet 45 is mounted on the slider 43. The storage unit 3 or the card taking mechanism 7 is provided with a numbered lead screw module 5. The numbered lead screw module 5 is drivingly connected to an adjusting block 51. The numbered lead screw module 5 is used to drive the adjusting block 51 to move. An electromagnet 52 for adsorbing the magnet 45 is mounted on the adjusting block 51, so that when the numbered lead screw module 5 drives the adjusting block 51 to move, the adjusting block 51 drives the conductive pulley 44 to move to a characteristic position of the resistive slider 42 by adsorbing the magnet 45 through the electromagnet 52, thereby adjusting the resistance value of the resistor.

[0073] 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 energizing the electromagnet 52, the electromagnet 52 adsorbs the magnet 45. Thereafter, when the numbered lead screw module 5 drives the adjusting block 51 to move, the electromagnet 52 on the adjusting block 51 drives the magnet 45 to move, and the magnet 45 drives the conductive pulley 44 to move to a characteristic position of the resistive slider 42, thereby realizing the adjustment of the resistance value of the resistor.

[0074] In some embodiments, when adjusting the resistance value of the resistor, the electromagnet 52 is energized. Thereafter, the numbered lead screw module 5 drives the adjusting block 51 to drive the electromagnet 52 to move from one end of the resistive slider 42 to the other end, so that the electromagnet 52 can adsorb the magnets 45 at different positions on the resistive slider 42; so that the electromagnet 52 can adsorb the magnets 45 staying at different positions on the slide rail 41, thereby realizing the ability to drive the magnets 45 at different positions to move.

[0075] In some embodiments, a finger 46 and a fixing spring 47 are mounted on the slider 43. The fixing spring 47 pushes the finger 46 to clamp the slide rail 41, so that the slider 43 is fixed at a certain position on the slide rail 41. The magnet 45 is floatingly arranged on the slider 43. When the electromagnet 52 adsorbs the magnet 45, the magnet 45 drives the finger 46 to separate from the slide rail 41, so that the slider 43 can slide on the slide rail 41.

[0076] When the electromagnet 52 does not adsorb the magnet 45, that is, when the resistance of the resistor does not need to be adjusted, the fixing spring 47 pushes the finger 46 to clamp the slide rail 41, so that the slider 43 is fixed at a certain position on the slide rail 41. Therefore, after editing the resistance value of the resistor, it is possible to prevent the slider 43 from moving due to the inertia of moving with the graphic card 8 and changing the resistance value.

[0077] When the electromagnet 52 adsorbs the magnet 45 and is ready to adjust the position of the slider 43, since the magnet 45 is floatingly arranged on the slider 43, when the electromagnet 52 adsorbs the magnet 45, the magnet 45 drives the finger 46 to separate from the slide rail 41, so that the slider 43 can slide on the slide rail 41.

[0078] To more clearly illustrate a graphic card storage device described in this specific embodiment, the following embodiments are listed. Embodiment

[0079] As Figures 1 to 6 shown, this embodiment provides a graphic card storage device, which is applied to an optical test system. The optical test system is provided with a card taking mechanism 7 for taking the graphic card 8 to the test space for the device under test to photograph.

[0080] The graphic card storage device includes a linear drive assembly 1 and a frame 2.

[0081] The linear drive assembly 1 includes a linear motor 11 and a track 12. The linear motor 11 is drivingly connected to a slide plate 13 that slides on the track 12.

[0082] The frame 2 is mounted on the slide plate 13. A plurality of storage units 3 for placing the graphic cards 8 are arranged in the frame 2.

[0083] At the bottom of the storage unit 3, there is a support bar 31. Arranged on the support bar 31 are support rollers 311 for supporting the graphic card 8. An inlet and outlet motor 312 is installed on the support bar 31. The inlet and outlet motor 312 is drivingly connected to a rotating shaft 313. The rotating shaft 313 is drivingly connected to the support rollers 311. On both sides of the support rollers 311, there are lower guiding rollers 314 for supporting both sides of the bottom edge of the graphic card 8. At one end of the support bar 31, there is a buffer pulley 315 for positioning the graphic card 8 and restricting the graphic card 8 from sliding out from one end. At the top of the storage unit 3, there is a fixing plate 32. In the middle of the fixing plate 32, there is a limiting groove 321 for the top end of the graphic card 8 to slide into.

The linear motor 11 is used to 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 card taking mechanism 7 can take and place the picture cards 8 in the storage unit 3.

[0090] Each of the image cards 8 is provided with a resistor and at least two signal contacts 33, and the resistance value of each of the resistors is different from each other, so that each of the image cards 8 obtains a unique number through different resistance values. The signal contact 33 is electrically connected to the resistor, and the signal contact 33 is located on the outer wall of the image card 8. The storage unit 3 and the card retrieval mechanism 7 are both provided with signal antennae 6 for contacting the signal contacts 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. Example

[0091] like Figures 1 to 9 As shown, this embodiment provides a picture card storage device, which is applied to an optical test system. The optical test system is provided with a card taking mechanism 7 for taking a picture card 8 into a test space for photographing a device under test.

[0092] The image card storage device includes a linear drive component 1 and a frame 2 .

[0093] 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 .

[0094] 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 .

[0095] A support bar 31 is provided at the bottom of the storage unit 3. Support rollers 311 for supporting the graphic cards 8 are arranged on the support bar 31. A feeding motor 312 is installed on the support bar 31. The feeding motor 312 is drivingly connected to a rotating shaft 313, and the rotating shaft 313 is drivingly connected to the support rollers 311. Lower guiding rollers 314 for supporting both sides of the bottom edge of the graphic card 8 are provided on both sides of the support rollers 311. A buffer pulley 315 is installed at one end of the support bar 31. The buffer pulley 315 is used to position the graphic card 8 and prevent the graphic card 8 from sliding out from one end. A fixing plate 32 is provided at the top of the storage unit 3. A limiting groove 321 for the top end of the graphic card 8 to slide into is provided in the middle of the fixing plate 32. Upper guiding rollers 322 for supporting both sides of the top edge of the graphic card 8 are provided on both sides of the limiting groove 321, so that the graphic card 8 can slide vertically onto the support rollers 311.

[0096] Each graphic card 8 is provided with a resistor and at least two signal contacts 33. The resistance values of each resistor are different from each other, so that each graphic card 8 can obtain a unique number through different resistance values. The signal contacts 33 are electrically connected to the resistors. The signal contacts 33 are located on the outer wall of the graphic card 8. Both the storage unit 3 and the card taking mechanism 7 are provided with signal antennas 6 for contacting the signal contacts 33. When the graphic 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 graphic cards 8 according to different resistance values, and position different graphic cards 8. When the resistor is set to a specific resistance,

[0097] by being able to infinitely accurately reach multiple decimal places of the resistance value and by being able to infinitely increase the resistance of the resistor (that is, the selection range of the resistance can be infinite), the resistances of the resistors on each graphic card 8 are made different from each other. When sensing the resistance value of the resistor, the display of the resistance value (numerical value) can be a specific long string of numbers. Therefore, by using this long string of numbers, different graphic cards 8 can be numbered, and thus information registration of different graphic cards 8 can be achieved.

[0098] The resistor includes a slide rail 41 and a resistance slide bar 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 resistance slide bar 42 and slides on the resistance slide bar 42. The conductive pulley 44 is electrically connected to one of the signal contacts 33. One end of the resistance slide bar 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 resistance slide bar 42, and achieve numbering of the graphic card 8.

[0099] A magnet 45 is installed on the slider 43, a numbered lead screw module 5 is installed on the storage unit 3 or the card taking mechanism 7, the numbered lead screw module 5 is drivingly connected to an adjusting block 51, the numbered lead screw module 5 is used to drive the adjusting block 51 to move, and an electromagnet 52 for adsorbing the magnet 45 is installed on the adjusting block 51, so that when the numbered lead screw module 5 drives the adjusting block 51 to move, the adjusting block 51 drives the conductive pulley 44 to move to a specific position of the resistance slide bar 42 by adsorbing the magnet 45 through the electromagnet 52, thereby adjusting the resistance value of the resistor. A finger 46 and a fixing spring 47 are installed on the slider 43, and the fixing spring 47 pushes the 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 adsorbs the magnet 45, the magnet 45 drives the finger 46 to separate from the slide rail 41, so that the slider 43 can slide on the slide rail 41.

[0100] When performing optical tests on different products in the optical test system, the linear motor 11 drives the slide plate 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. At this time, the feeding motor 312 drives the rotating shaft 313, and the rotating shaft 313 drives all the supporting rollers 311 to rotate, and the graphic card 8 in the specific storage unit 3 is taken out to the card taking mechanism 7 for the card taking mechanism 7 to take the graphic card 8 to the test space for a specific device under test to take pictures.

[0101] After the device under test completes the shooting test of a certain graphic card 8, the graphic card 8 in the card taking mechanism 7 is sent to the storage unit 3 for storage.

[0102] When performing a shooting test on a specific device under test, the graphic 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 plate 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 feeding motor 312 drives the rotating shaft 313, and the rotating shaft 313 drives all the supporting rollers 311 to rotate, and the graphic card 8 in the other specific storage unit 3 is taken out to the card taking mechanism 7 to create / replace different test environments for the device under test.

[0103] When encoding the graphic card 8 (i.e., adjusting the resistance value of the resistor of the graphic card 8), the signal antenna 6 is pre - contacted with the signal contact 33 to obtain the resistance value of the resistor. Thereafter, the electromagnet 52 is powered on, and the numbered lead screw module 5 drives the adjusting block 51 to drive the electromagnet 52 to move from one end of the resistance slide bar 42 to the other end, so that the electromagnet 52 can adsorb the magnet 45 at different positions on the resistance slide bar 42. Thereafter, when the numbered lead screw module 5 drives the adjusting block 51 to move, the electromagnet 52 on the adjusting block 51 drives the magnet 45 to move, and the magnet 45 drives the conductive pulley 44 to move to a specific position of the resistance slide bar 42, thereby realizing the adjustment of the resistance value of the resistor.

[0104] When the card 8 moves to a certain storage unit 3 or the card taking mechanism 7, and it is necessary to read the number of the card 8 for registering information of the card 8, obtaining information of the card 8, and positioning the card 8, only by contacting the signal antenna 6 with the signal contact 33 can the resistance value be read. According to the display of the resistance value (digital value), it can be a specific long string of numbers, so as to realize obtaining the code of the card 8.
