For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0032] like Figure 1 As shown, a memory card automatic test machine can realize automatic detection of memory cards, and can classify and discharge qualified products and defective products after detection, effectively improving the detection efficiency and detection accuracy of memory cards. The automatic test machine of this embodiment includes a workbench 1 and a loading mechanism 2, a detection mechanism 3 and a discharge mechanism 4 arranged in sequence along the workbench 1, wherein the memory card to be tested is stored in the loading mechanism 2, and after being loaded into the detection mechanism 3 and tested, it is discharged into the discharge mechanism 4 according to the test results for classified storage, thereby realizing the separation of qualified products and defective products. The bottom of the loading mechanism 2 and the unloading mechanism 4 of this embodiment are both provided with a switching component 5, and the switching component 5 can switch the loading position of the loading mechanism 2, so that when there are multiple groups of memory cards to be tested stored in the loading mechanism 2, the switching component 5 can switch the position of the loading mechanism 2 after the detection of one group of memory cards to be tested is completed, so as to load and test the other group of memory cards to be tested, which can avoid frequent adding of materials by operators and reduce labor costs; at the same time, the switching component 5 at the unloading mechanism 4 can switch the unloading position of the unloading mechanism 4, so that after the memory card detection is completed, qualified products and defective products can be respectively unloaded to different positions of the unloading mechanism 4 under the action of the switching component 5 according to the detection results, thereby realizing the automatic classification and unloading of qualified products and defective products in this embodiment.

[0033] like Figure 1 As shown, in this embodiment, a loading bracket 6 is set between the loading mechanism 2 and the detection mechanism 3, and a unloading bracket 7 is set between the detection mechanism 3 and the unloading mechanism 4, so that when the memory card is tested, it can be first transferred from the loading mechanism 2 and temporarily stored in the loading bracket 6, which is convenient for sequential loading and avoids affecting the memory card during the loading process; at the same time, after the tested memory card is tested in the detection mechanism 3, it can also be first transferred and temporarily stored in the unloading bracket 7, so that when the switching component 5 in the unloading mechanism 4 switches the unloading position of the unloading mechanism 4 according to the detection result, the tested memory card can first wait in the unloading bracket 7 for the unloading position to switch, avoiding occupying the position of the detection mechanism 3, so that when the memory card is unloading, the new memory card to be tested can be tested in the detection component, which can improve the detection efficiency of this embodiment.

[0034] In order to realize automatic loading and unloading of memory cards, the present embodiment sets a synchronous conveying mechanism 8 at the position corresponding to the workbench 1 and the detection mechanism 3, which can convey the memory cards to be tested temporarily stored in the loading bracket 6 to the detection mechanism 3 for detection, and at the same time convey the tested memory cards that have completed the detection in the detection mechanism 3 to the unloading bracket 7, which not only realizes the automatic loading and unloading of memory cards, but also realizes the synchronization of loading and unloading, which can effectively improve the detection efficiency and simplify the overall structure of the memory card testing machine.

[0035] Specifically, Figure 1 and Figure 2 As shown, the synchronous conveying mechanism 8 of this embodiment includes a conveying frame 81 and a synchronous plate 82, wherein the conveying frame 81 is fixedly installed on the workbench 1 and is located at the rear side of the detection mechanism 3, and the left and right sides of the conveying frame 81 extend to the rear of the loading bracket 6 and the unloading bracket 7 respectively. At the same time, the surface of the conveying frame 81 is provided with a conveying track arranged along its length direction. The synchronous plate 82 of this embodiment is slidably installed on the conveying track on the surface of the conveying bracket, so that it can move along the conveying track to the loading bracket 6 to load the storage card or move along the conveying track to the unloading bracket 7 to unload the storage card.

[0036] In order to realize the loading and unloading of memory cards, lifting rails 83 are vertically installed on both sides of the end surface of the synchronization plate 82 of the present embodiment facing the detection mechanism 3, wherein a conveying suction cup 84 is movably installed on the lifting rail 83 close to the side of the loading bracket 6, and the conveying suction cup 84 can move downward under the action of the lifting rail 83 to adsorb the memory card temporarily stored on the unloading bracket 7, and then move to the top of the detection mechanism 3 under the action of the synchronization plate 82 to place the memory card on the detection mechanism 3 for detection, thereby realizing the loading of the memory card; a detection head 85 is movably installed on the lifting rail 83 close to the side of the unloading bracket 7 of the present embodiment, and unloading suction cups 851 are arranged around the bottom of the detection head 85, and the detection head 85 can be moved down by the lifting rail and pressed on the detection mechanism 3 to detect the memory card. After the detection is completed, the unloading suction cups 851 around its bottom absorb the detected memory card, and are moved to the unloading bracket 7 for storage under the drive of the synchronization plate 82, thereby realizing the detection and unloading of the memory card.

[0037] In this embodiment, the distance between the two lifting rails 83 is the same as the distance between the loading bracket 6 and the detection mechanism 3 and the distance between the detection mechanism 3 and the unloading bracket 7, so that when the conveying suction cup 84 adsorbs the storage card at the loading bracket 6, the detection head 85 is just located at the position of the detection mechanism 3 under the action of the synchronization plate 82 to perform downward pressure detection on the storage card on the detection mechanism 3; after the detection is completed, when the unloading suction cup 851 at the bottom of the detection head 85 adsorbs the tested storage card and transfers it to the unloading bracket 7, the conveying suction cup 84 can be located above the detection mechanism 3 under the action of the synchronization plate 82, thereby placing the storage card adsorbed from the loading bracket 6 on the detection mechanism 3, realizing the simultaneous loading and unloading of this embodiment, effectively improving the detection efficiency, and simplifying the overall structure of the testing machine, which is convenient for miniaturization.

[0038] In order to realize the movement of the synchronization plate 82, thereby realizing the synchronization of loading and unloading in this embodiment, a horizontally arranged transmission motor is arranged at one end of the transmission frame 81 in this embodiment, and a transmission screw rod arranged along the length direction of the synchronization plate 82 is connected to the output shaft of the transmission motor, and the back of the synchronization plate 82 is threadedly connected to the transmission screw rod, so that when the transmission motor is started, it can drive the transmission screw rod to rotate, and the synchronization plate 82 can move along the transmission screw rod under the action of the thread, so as to realize the movement of the synchronization plate 82 on the transmission track, and then the transmission suction cup 84 and the detection head 85 on the left and right sides of the synchronization plate 82 can move simultaneously under the action of the synchronization plate 82, so as to realize the function of synchronous loading and unloading in this embodiment.

[0039] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the storage card is adsorbed from the loading bracket 6 by the conveying suction cup 84 of the synchronous conveying mechanism 8 and placed on the detection mechanism 3, and the detection head 85 of the synchronous conveying mechanism 8 is pressed down onto the detection mechanism 3 to realize the downward pressure detection of the storage card; the detection mechanism 3 of this embodiment includes a detection table 31 arranged on the workbench 1, an elastic buffer 32 arranged on the end surface of the detection table 31 and a detection fixture 33 connected to the top of the elastic buffer 32, and the storage card can be placed on the detection fixture 33 for detection, which can ensure the detection accuracy. The detection fixture 33 of the present embodiment is provided with a plurality of detection holes 331 corresponding to the contacts of the memory card, and the end surface of the detection platform 31 is provided with a support stem and a detection pin 311 inserted into the detection hole 331. When no detection is performed, the detection fixture 33 is lifted up by the elastic buffer 32, so that the detection pin 311 is hidden in the detection hole 331, which can avoid the memory card being directly contacted with the detection pin 311 when placed on the detection fixture 33, resulting in detection errors and other problems. When performing detection, the detection head 85 is moved down under the drive of the lifting slide rail 83 to press on the detection pin 311. On the testing jig 33, the testing jig 33 moves downward to compress the elastic buffer 32 and make the testing pin 311 pass through the testing hole 331 and contact the contact on the memory card, and then the memory card is powered on to test whether the memory card can work normally; after the detection is completed, the unloading suction cup 851 on the detection head 85 sucks the memory card and moves it upward and transfers it to the unloading bracket 7. The testing jig 33 moves upward under the action of the elastic buffer 32 to make the testing pin 311 return to the testing hole 331, which can protect the testing pin 311 and prevent the testing pin 311 from being worn.

[0040] The detection mechanism 3 of this embodiment is detachably connected to the workbench 1, so that when this embodiment detects a certain type of memory card, the detection mechanism 3 can be disassembled and replaced with an appropriate detection mechanism 3, which is suitable for the detection of various memory cards and has a wide range of applications.

[0041] like Figure 1 and Figure 4 As shown, the present embodiment stacks and stores the memory cards to be tested and the memory cards that have been tested by means of a loading mechanism 2 and a unloading mechanism 4, respectively, wherein the loading mechanism 2 and the unloading mechanism 4 both include a storage table 21 and a storage rack 22 provided on the storage table 21 for stacking and storing the memory cards. The storage rack 22 of the present embodiment is a square frame structure connected at both ends, and an opening at one end of the storage rack 22 of the loading mechanism 2 corresponds to a loading bracket 6, so that the memory cards to be tested stored in the storage rack 22 of the loading mechanism 2 can enter the loading bracket 6 through the opening for temporary storage and loading; an opening at one end of the storage rack 22 of the unloading mechanism 4 corresponds to an unloading bracket 7, so that the tested memory cards temporarily stored on the unloading bracket 7 can enter the storage rack 22 through an opening at one end of the storage rack 22 to complete unloading.

[0042] like Figure 4 and Figure 5 As shown, in the present embodiment, a plurality of storage racks 22 are arranged side by side, and the storage table 21 is connected to the switching component 5, so that during the process of storage card loading detection or unloading and classification storage, the switching component 5 can drive the storage table 21 to move, so that the storage rack 22 in the loading mechanism 2 and the storage rack 22 in the unloading mechanism 4 can be switched respectively under the action of the switching component 5, realizing the switching of the loading position and the unloading position, thereby realizing the functions of group loading and automatic classification unloading. Specifically, the switching assembly 5 of the present embodiment includes a mounting plate 51 and a switching track 52 and a switching motor 53 which are arranged on the mounting plate 51 and along the arrangement direction of the material storage rack 22, wherein the material storage table 21 is slidably mounted on the switching track 52, and the output shaft of the switching motor 53 is connected to a switching screw which is threadedly connected to the material storage table 21, so that when the switching motor 53 is started, it can drive the switching screw to rotate, so that the material storage table 21 moves along the switching track 52 under the action of the threaded connection, so that the loading bracket 6 or the unloading bracket 7 corresponds to another material storage rack 22 arranged side by side in the loading mechanism 2 or the unloading mechanism 4, respectively, thereby realizing the automatic switching of the loading position and the unloading position of the present embodiment, reducing the manual feeding process, and realizing the automatic classification and storage of qualified products and defective products.

[0043] like Figure 6 and Figure 8 As shown, the loading bracket 6 and the unloading bracket 7 of this embodiment both include a mounting bracket 61 fixedly mounted on the workbench 1 and mounting blocks 62 symmetrically arranged on both sides of the top of the mounting bracket 61, and the two mounting blocks 62 are combined to form a transmission channel 63 adapted to the memory card. In addition, the two mounting blocks 62 of this embodiment are arranged parallel to the moving direction of the memory card, so that the feeding end or the discharging end of the transmission channel 63 formed by the combination of the two mounting blocks 62 can correspond to and be connected to the port of the storage rack 22, thereby enabling the memory card in the storage rack 22 of the loading mechanism 2 of this embodiment to directly enter the transmission channel 63 of the loading bracket 6 from the port of the storage rack 22 to realize loading, and at the same time, the memory card in the transmission channel 63 of the unloading bracket 7 can also directly enter the unloading mechanism 4 through the port of the storage rack 22 to realize unloading.

[0044] like Figure 1 and Figure 7As shown, in order to move the memory card to be tested in the loading mechanism 2 to the conveying channel 63 of the loading bracket 6 for loading, a loading pushing component 64 is arranged at the end of the loading mechanism 2 away from the loading bracket 6 in this embodiment, and the loading pushing component 64 corresponds to the port of the storage rack 22, and can push the memory card from the port on one side of the storage rack 22 to enter from the port on the other side of the storage rack 22 into the conveying channel 63 of the loading bracket 6 to wait for the synchronous conveying component to adsorb and load; in order to move the tested memory card in the conveying channel 63 of the unloading bracket 7 to the storage rack 22 of the unloading mechanism 4 for storage, a unloading pushing component 71 is arranged on the unloading bracket 7 in this embodiment, and the unloading pushing component 71 can push the tested memory card on the conveying channel 63 of the unloading bracket 7 from the port of the storage rack 22 into the storage rack 22 for unloading and storage.

[0045] Specifically, Figure 7 As shown, the loading pushing assembly 64 of the present embodiment includes a pushing frame 641 fixedly mounted on the workbench 1, a loading track 642 horizontally arranged on the pushing frame 641 and extending toward the loading mechanism 2, and a push rod 643 slidably mounted on the loading track 642. The pushing frame 641 of the present embodiment corresponds to the port of the material storage rack 22 of the loading mechanism 2, so that the push rod 643 can be inserted from the port of the material storage rack 22 away from the loading bracket 6, thereby pushing the storage card stored in the material storage rack 22 from the port on the other side of the material storage rack 22 into the loading bracket 6 for loading; in order to realize the movement of the push rod 643 and thus push the storage card into the loading bracket 6, the present embodiment is provided with a loading driving assembly 644 on the pushing frame 641, which can drive the push rod 643 to move along the loading track 642 so as to be inserted into the material storage rack 22 to push the storage card for loading.

[0046] like Figure 7 As shown, the loading drive assembly 644 of this embodiment includes transmission wheels arranged at both ends of the pushing frame 641, a transmission motor connected to any transmission wheel and a transmission belt mounted on the transmission wheel, and the push rod 643 is connected to one side of the transmission belt, so that when the transmission motor is started to drive the transmission wheel to rotate, the transmission belt can rotate under the drive of the transmission wheel, thereby driving the push rod 643 connected to one side of the transmission belt to move, and then the push rod 643 can be inserted into the storage rack 22 under the drive of the transmission belt to push the storage card to move to the loading bracket 6.

[0047] like Figure 8As shown, the material unloading and pushing assembly of this embodiment includes a material unloading track 711 arranged on one side of the conveying channel 63 and a pushing block 712 movably mounted on the material unloading track 711. The pushing block 712 of this embodiment is arranged on the side of the conveying channel 63 away from the material unloading bracket 7. When the synchronous conveying assembly adsorbs the measured memory card to unload it onto the unloading bracket 7, the pushing block 712 abuts against the side of the memory card away from the unloading bracket 7. The pushing block 712 moves along the material unloading track 711 to push the memory card from the conveying channel 63 to the storage rack 22 of the unloading mechanism 4, thereby completing the unloading and storage of the memory card. The unloading bracket 7 of this embodiment is also provided with a material unloading drive assembly 713 connected to the pushing block 712, so that the pushing block 712 can move along the material unloading track 711 driven by the material unloading drive assembly 713, thereby pushing the unloading and storage of the memory card.

[0048] Specifically, the unloading drive assembly 713 of the present embodiment includes driving wheels arranged at both ends of the unloading bracket 7, a driving motor connected to any driving wheel and a driving belt mounted on the driving wheel. The pushing block 712 is connected to one side of the driving belt, so that when the driving motor is started to drive the driving wheel to rotate, the driving belt can rotate under the drive of the driving wheel, thereby driving the pushing block 712 connected to one side of the driving belt to move, and then the pushing block 712 can be driven by the driving belt to move along the conveying channel 63 on the unloading bracket 7, thereby pushing the storage card in the conveying channel 63 of the unloading bracket 7 to the storage rack 22 of the unloading mechanism 4.

[0049] The loading drive assembly 644 and the unloading drive assembly 713 of the present embodiment are both belt drive mechanisms. In another embodiment, the loading drive assembly 644 and the unloading drive assembly 713 may also be cylinder drive mechanisms. The same technical effect can be achieved by arranging a cylinder on the pushing frame 641 and at a position of the unloading bracket 7 away from one end of the unloading mechanism 4 to push the storage card, which will not be repeated here.

[0050] In this embodiment, a loading push component 64 is provided to push the storage cards in the storage rack 22 into the loading bracket 6, and a unloading push component 71 is provided to push the storage cards on the unloading bracket 7 into the storage rack 22 of the unloading mechanism 4 for storage, thereby realizing the loading and unloading storage of the storage cards; at the same time, during the unloading and storage process of the loading machine, the switching component 5 can be equipped to switch the loading position of the loading mechanism 2 and the unloading position of the unloading mechanism 4, thereby realizing the function of loading multiple groups of storage cards and realizing the function of classified storage of qualified storage cards and defective storage cards.

[0051] like Figure 1 , Figure 4 and Figure 5As shown, a lifting assembly 10 for driving the material storage rack 22 to lift vertically is further provided at the bottom of the mounting plate 51 of the present embodiment. The lifting assembly 10 can drive the material storage rack 22 to move up and down, so that when the stacking height changes due to loading or unloading of the memory cards stacked and stored in the material storage rack 22, the lifting assembly 10 can start to adjust the height position of the material storage rack 22, thereby facilitating the loading of the next layer of memory cards or stacking the detected memory cards and storing them on the material storage rack 22 of the unloading mechanism 4. Specifically, the lifting assembly 10 of the present embodiment includes a lifting motor, a lifting screw and a lifting nut seat. The lifting nut seat of the present embodiment is fixedly installed on the workbench 1, and the lifting motor is arranged at the bottom of the workbench 1. One end of the lifting screw is connected to the driving shaft of the lifting motor, and the other end of the lifting screw passes through the lifting nut seat and is connected to the bottom of the switching assembly 5. At the same time, a lifting guide rod is connected between the switching assembly 5 and the lifting motor, so that when the lifting motor is started, the lifting screw is driven to rotate. At this time, the threaded connection between the lifting screw and the lifting nut seat causes the lifting screw to move up and down, thereby driving the switching assembly 5 and the lifting motor to move vertically under the action of the lifting guide rod, thereby driving the storage rack 22 connected to the lifting guide rod to move up and down, realizing the switching of the height position of the storage rack 22, and facilitating the loading or unloading of storage cards.

[0052] like Figure 1 and Figure 2 As shown, a laser marking mechanism 9 is further provided on the workbench 1 of the present embodiment and at a position corresponding to the unloading bracket 7. The laser marking mechanism 9 can laser mark unqualified memory cards, thereby recording the unqualified memory cards for easy identification by the staff; specifically, the laser marking mechanism 9 of the present embodiment includes a vertically arranged movable slide rail 91 and a mounting seat 92 slidably mounted on the movable slide rail 91, a laser 93 is fixedly mounted on the mounting seat 92, and the laser 93 is arranged toward the unloading bracket 7, so that after the memory card is detected in the detection mechanism 3 and transferred to the unloading bracket 7 driven by the synchronous transmission component, the laser 93 can laser mark the surface of the unqualified memory card from top to bottom, thereby marking the unqualified memory card; a height adjustment component 94 connected to the mounting seat 92 is also provided on the top of the movable slide rail 91 of the present embodiment, so that the laser 93 can adjust the height position under the action of the height adjustment component 94, so as to facilitate accurate marking.

[0053] Specifically, the height adjustment assembly 94 of this embodiment includes a rotating handle arranged on the top of the movable slide rail 91 and an adjusting screw rod vertically connected to the bottom of the rotating handle, wherein the adjusting screw rod passes through the mounting seat 92 and is threadedly connected to the mounting seat 92, so that when the rotating handle is rotated, the adjusting screw rod can be driven to rotate, and then the mounting seat 92 can be moved up and down along the movable slide rail 91 under the action of the threaded connection, thereby adjusting the height of the laser 93 on the mounting seat 92, and the adjustment method is convenient.

[0054] In summary, the working principle of this embodiment is:

[0055] In this embodiment, a loading mechanism 2, a detection mechanism 3 and a unloading mechanism 4 are arranged on a workbench 1, so that when the memory card is detected, it can be automatically loaded from the loading mechanism 2 to the detection mechanism 3 for detection, and then automatically unloaded into the unloading mechanism 4 after the detection is completed, thereby realizing automatic detection of the memory card.

[0056] Furthermore, by arranging a switching component 5 at the bottom of the loading mechanism 2 and the bottom of the unloading mechanism 4, the switching component 5 can switch the loading position during the loading process, thereby reducing the number of manual filling times. At the same time, the switching component 5 can switch the unloading position, so that the present application can switch the unloading position of the memory card according to the detection results, thereby realizing the automatic separation of qualified products and defective products.

[0057] At the same time, this embodiment sets a synchronous transmission component at the position corresponding to the workbench 1 and the detection mechanism 3, so that after the memory card detection is completed, it can be transferred to the unloading mechanism 4 under the action of the synchronous transmission mechanism 8. At the same time, during the transfer and unloading process, the synchronous transmission mechanism 8 can also simultaneously transfer the new memory card to be tested to the detection mechanism 3 for testing, thereby realizing the simultaneous loading and unloading of the memory card, which can effectively improve the detection efficiency.

Any non-substantial changes and modifications made by those skilled in the art on the basis of the invention shall fall within the protection scope of the present invention.
