When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] The present invention provides an automatic testing device, referring to Figures 1 to 3 The automatic testing device includes a material taking and turning mechanism 100, a mounting mechanism 200 and a testing mechanism.

[0039] The testing mechanism includes a main conveyor belt 301, a jig reflux structure 302 and a plurality of aging jigs 303. The main conveyor belt 301 has a feed position 3011 and a discharge position 3012. The jig reflux structure 302 has a feed end and a discharge end. The feed end of the jig reflux structure 302 is cascaded to the discharge position 3012 of the main conveyor belt 301. The discharge end of the jig reflux structure 302 is cascaded to the feed position 3011 of the main conveyor belt 301. The plurality of aging jigs 303 are transmission-connected to the main conveyor belt 301. Each of the aging jigs 303 is provided with a plurality of testing positions 3031.

[0040] The material taking and flipping mechanism 100 is used to transfer the adapter to be tested and perform an angle flipping process on the adapter to be tested according to the test position 3031 .

[0041] The installation mechanism 200 is used to plug the adapters to be tested into the test positions 3031 one by one.

[0042] In one example, the mounting mechanism 200 may be disposed above the feed of the main conveyor belt 301 to plug the adapters to be tested one by one into the aging fixture 303 entering the main conveyor belt 301 .

[0043] It should be noted that the aging fixture here can be provided with a test circuit, and the adapter to be tested is plugged into the test position 3031 corresponding to the aging fixture, so that each adapter to be tested is connected to the test circuit of the corresponding test position 3031. According to actual use, a test station can be set at the discharge position 3012 of the main conveyor belt 301, and a backplane can be set at the test station. The backplane is provided with a circuit, and each aging fixture 303 is provided with a connecting terminal. The aging fixture 303 conveyed from the feed position of the main conveyor belt 301 to the discharge position 3012 is connected to the backplane circuit through the connecting terminal, and the corresponding adapter to be tested is judged whether it is a good product according to whether the circuit is conductive, thereby completing the performance test of the adapter to be tested, and the product quality of the power adapter can be further controlled through the performance test.

[0044] A material picking and flipping mechanism 100 is provided, which takes out the adapter to be tested transmitted from the previous process, and performs an angle flipping process on the adapter to be tested according to the test position 3031 of the aging fixture 303 before testing, so that the adapter to be tested can be aligned with the test position 3031 when being transmitted to the test position 3031, thereby avoiding positional deviation of the adapter to be tested, and effectively improving the test quality and stability.

[0045] To improve the test efficiency, each aging fixture 303 is provided with a plurality of test positions 3031 to perform performance tests on each adapter to be tested at the same time. The adapter to be tested is clamped and plugged in by the jack of the test position 3031 of the aging fixture 303 to complete the plugging of the AC end of the adapter to be tested, thereby avoiding the need to manually complete the plugging of the AC end and the DC end at the same time, simplifying the processing procedure, and reducing dependence on manual labor and processing errors.

[0046] Optionally, in the automatic testing device described in the present invention, a manual workstation can be set along the main conveyor belt 301 for inserting the DC end of the tape product into the testing position.

[0047] In one embodiment, the jig reflow structure 302 further includes a plurality of detection components 3043 and a plurality of first blocking structures 3041 .

[0048] Each of the detection components 3043 is arranged along the conveying direction of the main conveyor belt 301 and is used to detect the position of the aging fixture 303 .

[0049] A plurality of first blocking structures 3041 are arranged at intervals along the conveying direction of the main conveyor belt 301 , and are used to block the aging jig 303 when the aging jig 303 is detected.

[0050] It can be understood that the plurality of detection components 3043 correspond one-to-one to the plurality of first blocking structures 3041, and the position of the aging jig 303 is detected by the detection component 3043. The blocking structure can be a cylinder or connected to a cylinder. When the aging jig 303 is detected to be approaching, the blocking structure automatically rises to block the passage of the corresponding aging jig 303 so as to manually insert the DC end of the product with a line. The detection component 3043 can use a camera device, a position sensor, etc. to detect whether there is an aging jig approaching on the main conveyor belt.

[0051] In one embodiment, the main conveyor belt 301 is further provided with a first blocking switch, and there are multiple first blocking switches. The multiple first blocking structures 3041 are divided into multiple blocking groups, and each blocking group includes at least one first blocking structure 3041. The multiple blocking switches are connected to the multiple blocking groups one by one, and each blocking switch is used to control the work of the corresponding connected blocking group to release the aging jig 303. After completing the manual plugging, the corresponding blocking switch is manually pressed, and the blocking structure descends to release the corresponding aging jig 303.

[0052] In one example, one blocking group is used to block one aging fixture. According to actual conditions, a plurality of the blocking groups may be arranged at intervals along the main conveyor belt to block a plurality of aging fixtures accordingly.

[0053] Optionally, the main conveyor belt can be set as a guide rail structure, the aging jig is placed on the guide rail structure and moves along the guide rail structure, the main conveyor belt can include one or more guide rail structures, and the first blocking switch is fixed and does not move with the main conveyor belt. When the main conveyor belt has only one guide rail structure, the first blocking switch can be set on the side of the guide rail structure or close to the guide rail structure to achieve blocking of the aging jig; when there are multiple guide rail structures, the aging jig is set between multiple guide rail structures to follow the movement, and the first blocking switch is set between the multiple guide rail structures to achieve blocking of the aging jig.

[0054] In one embodiment, in order to prevent the aging jig 303 from backflowing, the main conveyor belt 301 is further provided with a plurality of second blocking structures 3042 , and each of the second blocking structures 3042 is provided between any two adjacent first blocking structures 3041 .

[0055] Although the automatic testing device shown in the present invention can limit the movement of the corresponding aging jig 303 through the first blocking structure 3041, since the main conveyor belt 301 is in a conveying operation state from the beginning, the first blocking structure 3041 only limits the forward movement of the aging jig 303 but cannot limit the backward movement of the aging jig 303 due to rebound or the like after the forward movement is blocked. The second blocking structure 3042 is provided to prevent the corresponding aging jig 303 from flowing back.

[0056] Optionally, multiple second blocking structures 3042 may be provided, and multiple second blocking structures 3042 may be divided into multiple groups, each group including at least one second blocking structure 3042. Further, a control switch may be provided, and multiple control switches may be provided. According to actual needs, optionally, multiple control switches may be connected one-to-one with multiple groups of second blocking structures 3042, and each control switch may be used to control the operation of each correspondingly connected group of second blocking structures 3042 to prevent the aging jig 303 from flowing back. The operation of the second blocking structure 3042 may be controlled by setting the control switch.

[0057] The specific implementation of the second blocking structure is similar to that of the first blocking structure, and will not be described in detail herein.

[0058] In one embodiment, the jig reflow structure 302 includes a reflow conveyor belt 3021, a first lifting assembly 3022 and a second lifting assembly (not shown in the figure), the reflow conveyor belt 3021 is opposite to the conveying direction of the main conveyor belt 301, the feed position 3011 of the main conveyor belt 301 is cascaded with the first lifting assembly 3022, the discharge position 3012 of the main conveyor belt 301 is cascaded with the second lifting assembly, the reflow conveyor belt 3021 has a feed position and a discharge position, the feed position of the reflow conveyor belt 3021 is cascaded with the second lifting assembly, and the discharge position of the reflow conveyor belt 3021 is cascaded with the first lifting assembly 3022.

[0059] The position where the second lifting component is connected to the main conveyor belt 301 is used as the feed end of the jig reflux structure 302, and the position where the first lifting component 3022 is connected to the main conveyor belt 301 is used as the discharge end of the jig reflux structure 302. The jig reflux structure 302 is set, and the aging jig 303 is transferred from the feed position 3011 of the main conveyor belt 301 to the discharge position 3012, and the performance test of the adapter to be tested is completed at the discharge position 3012 of the main conveyor belt 301. After the test is completed, the adapter can be removed from the aging jig 303, and the aging jig 303 is refluxed to the main conveyor belt 301 through the jig reflux structure 302.

[0060] Of course, according to actual use, if the aging jig 303 is provided with test positions 3031 on both sides, it is not ruled out that a flipping structure is provided at the connection end of the first lifting structure and / or the connection end of the second lifting structure, so that the aging jig 303 is flipped after entering the jig reflow structure 302 and is re-uploaded to the main conveyor belt 301, so that the adapter to be tested can be plugged one-to-one into the test position 3031 on the other side.

[0061] Optionally, the first blocking switch and the second blocking switch may also be arranged on the return conveyor belt 3021. The specific implementation of the first blocking switch and the second blocking switch arranged on the return conveyor belt is similar to the above-mentioned implementation of being arranged on the main transmission belt, and will not be repeated here.

[0062] In one embodiment, the automatic testing device also includes a transfer mechanism, which is installed between the material picking and flipping mechanism 100 and the installation mechanism 200. The transfer mechanism includes a transmission assembly and a transfer station 402. The transmission assembly has a relative starting position 4011 and a test position 4012 along its transmission direction. The starting position 4011 is adjacent to the material picking and flipping mechanism 100, and the test position 4012 is adjacent to the installation mechanism 200. The transfer station 402 is arranged on the transmission path of the transmission assembly and is used to move back and forth between the material picking and flipping mechanism 100 and the installation mechanism 200.

[0063] It is understandable that the transfer station 402 is in transmission connection with the transmission assembly to drive the transfer station 402 to move back and forth between the starting position 4011 and the test position 4012, so as to transfer the adapter to be tested to the installation mechanism 200 to test the adapter to be tested. In one example, the transmission assembly adopts a transmission device such as a cylinder.

[0064] In one embodiment, the transfer mechanism also includes a first movable guide rail 403 and a mounting frame 404, there are two first movable guide rails 403, the two first movable guide rails 403 are spaced apart at the top of the transfer mechanism, the mounting mechanism 200 is disposed on the mounting frame 404, and the mounting frame 404 is erected between the two first movable guide rails 403, for allowing the mounting mechanism 200 to move back and forth between the transfer mechanism and the testing mechanism.

[0065] Optionally, two of the first movable rails 403 may be disposed on both sides of the transfer mechanism, and the installation mechanism 200 may use an installation robot arm to clamp the adapter to be tested and plug the adapter to be tested into the corresponding test position 3031 one by one.

[0066] Furthermore, the installation mechanism 200 is arranged to be liftable on the installation frame 404. In one example, the main conveyor belt 301 is arranged below the transfer mechanism. Based on this example, the installation robot arm is also provided with a lifting component 201, and the clamping claw of the installation robot arm is arranged on the lifting component 201, so that the installation robot arm can move back and forth between the transfer mechanism and the testing mechanism. The clamping claw of the installation robot arm is driven by the lifting component 201 to approach and / or move away from the aging fixture 303 of the main conveyor belt 301.

[0067] Optionally, the adapter to be tested is provided with a barcode, and the barcode is provided on each adapter to be tested in the form of pasting or laser engraving.

[0068] In one embodiment, the transfer mechanism further includes a scanning component, a recovery mechanism 406 and a second movable guide rail 4041 .

[0069] The scanning component is disposed between the starting position 4011 and the position to be tested 4012, and is used to scan the adapter to be tested on the transfer mechanism to determine whether the adapter to be tested is a defective product.

[0070] The recovery mechanism 406 is arranged on the side of the transmission assembly in alignment with the scanning assembly.

[0071] The second movable guide rail 4041 is disposed on the mounting frame 404 , and the mounting mechanism 200 is slidably connected to the second movable guide rail 4041 .

[0072] When the adapter to be tested is a defective product after scanning, the installation mechanism 200 is used to transfer the adapter to be tested to the recycling mechanism 406;

[0073] When the adapter to be tested is not a defective product after scanning, the installation mechanism 200 is used to plug the adapter to be tested into the test position 3031 one by one.

[0074] Optionally, a scanning station 4051 can be set in the transmission component of the transfer mechanism. The scanning station 4051 is set between the starting position 4011 and the position to be tested 4012 and is set close to the position to be tested 4012. The scanning component is set at the scanning station 4051 or the scanning component is set close to the transmission component of the transfer mechanism, so that the scanning component can scan and process the adapter to be tested entering the scanning station 4051. The barcode of each adapter to be tested is scanned by the scanning component to perform a preliminary screening of the adapter to be tested, and defective products are screened out to reduce the workload of subsequent performance testing. Defective products are recycled by the recycling mechanism 406 to avoid mixing defective products with other adapters to be tested, resulting in repeated processing. Specifically, the code scanning component can be connected to the control circuit of the automatic testing device, and the code scanning component transmits the detection signal to the control circuit. When the adapter to be tested is a defective product, the control circuit controls the installation mechanism 200 to transfer the adapter to be tested to the recycling mechanism; when the adapter to be tested is not a defective product, the control circuit controls the installation mechanism 200 to plug the adapter to be tested into the test position 3031 one by one.

[0075] Optionally, the transfer mechanism may be provided with one or more transfer stations 402. Corresponding to the number of the transfer stations 402, one or more conveying components may be provided to respectively convey each transfer station. Similarly, one or more scanning components may be provided to scan one or more adapters to be tested on the transfer mechanism, with one clamp grasping one adapter accordingly. The installation robot may be provided with one or more clamps.

[0076] In one embodiment, the material taking and turning mechanism 100 includes a lifting robot arm 101 and a conversion robot arm 102 .

[0077] The lifting mechanical arm 101 is used to grab and transfer the adapter to be tested. The lifting mechanical arm 101 performs a first flipping process on the adapter to be tested in a first direction during the transfer of the adapter to be tested.

[0078] The conversion mechanical arm 102 is disposed above the lifting mechanical arm 101 and is used to transfer the adapter to be tested that has completed the first flipping process. The conversion mechanical arm 102 performs a second flipping process on the adapter to be tested toward a second direction during the process of transferring the adapter to be tested.

[0079] Optionally, the lifting robot arm 101 is used to grab and transfer the adapter to be tested that flows in from the previous process, and flip the adapter to be tested according to the angle difference between the adapter to be tested and the test position, so that the adapter to be tested can be directly plugged into the test position 3031 when it is transferred to the testing organization without further angle adjustment.

[0080] It should be noted that the first direction and the second direction can be defined here according to the flipping direction in the actual implementation process, and the first direction includes but is not limited to rotating 180° counterclockwise or clockwise to complete vertical flipping, and rotating 180° in the direction toward or away from the main conveyor belt 301 to complete horizontal flipping; the same applies to the second direction. In one example, if the AC end of the adapter to be tested flowing in from the previous process is facing upward, the adapter to be tested can be flipped for the first time by the lifting mechanical arm 101, and the second flipping can be performed by the conversion mechanical arm 102. Specifically, the adapter to be tested can be flipped vertically first and then horizontally; or vice versa. Specifically, the lifting mechanical arm 101 performs the first flipping process on the adapter to be tested in the first direction during the conversion of the adapter to be tested, so that the adapter to be tested completes vertical flipping, and the conversion mechanical arm 102 performs the second flipping process on the adapter to be tested in the second direction during the conversion of the adapter to be tested, so that the adapter to be tested completes horizontal flipping; or vice versa. Optionally, the clamping claws of the lifting robot arm 101 are parallel to the plane where the main transmission belt is located, and the clamping claws of the conversion robot arm 102 are perpendicular to the plane where the main conveyor belt 301 is located. To facilitate adjustment and flipping, the lifting robot arm 101 can be arranged to drive the adapter to be tested to rotate 180° counterclockwise or clockwise, and the conversion robot arm 102 can drive the adapter to be tested to rotate 180° in the direction toward or away from the main conveyor belt 301.

[0081] Optionally, according to actual use, it is not excluded to set one or two lifting mechanical arms 101. When one lifting mechanical arm 101 is set, the lifting mechanical arm 101 drives the adapter to be tested to rotate 180° counterclockwise or clockwise to complete the vertical flip; when two lifting mechanical arms 101 are set, the lifting mechanical arm 101 includes a first lifting mechanical arm 1011 and a second lifting mechanical arm 1012. The first lifting mechanical arm 1011 drives the adapter to be tested to rotate 90° counterclockwise or clockwise, and the second lifting mechanical arm 1012 drives the adapter to be tested to continue to rotate 90° in the same direction to jointly complete the vertical flip. Of course, it is not excluded that when two lifting mechanical arms are provided, the first lifting mechanical arm 1011 drives the adapter to be tested to rotate 180° counterclockwise or clockwise to complete the vertical flip, and the second lifting mechanical arm 1012 only serves as a transmission to transmit the adapter to be tested to the bottom of the conversion mechanical arm 102.

[0082] Optionally, one clamp is used to grasp one adapter, and the first lifting robot arm 1011 may be provided with one or more clamps, and the second lifting robot arm 1012 and the conversion robot arm 102 may be provided with one or more clamps.

[0083] Optionally, the lifting robot arm 101 and the conversion robot arm 102 are suspended above a conveyor belt, and the adapter to be tested that has completed the first flipping process can be conveyed to the bottom of the conversion robot arm 102 through the conveyor belt.

[0084] In one embodiment, the material picking and flipping mechanism 100 further includes a third movable guide rail 103, and the conversion robot arm 102 is slidably connected to the third movable guide rail 103, so as to transfer the adapter to be tested to the transfer mechanism.

[0085] In one example, the third transfer rail is arranged toward the transfer mechanism. Optionally, according to actual use, another transfer rail can be arranged on the material picking and flipping mechanism, and the transfer rail is perpendicular to the transfer direction of the transfer mechanism transfer component. The transfer mechanism can be provided with a plurality of transfer stations, and the third transfer rail is connected to the transfer rail in a transmission manner to drive the conversion bracket to clamp the adapter to be tested to a plurality of transfer stations.

[0086] Optionally, the automatic test device of the present invention can be assembled to a mounting bracket 500, and a roller can be assembled at the bottom of the mounting bracket 500 according to actual use. To avoid mutual interference affecting operation, the various structural components of the automatic test device of the present invention can be aligned in advance, and the running time, running speed, running path and running steps can be preset, so that each structural component operates according to the preset execution process.

[0087] The specific implementation process of the automatic testing device shown in the present invention is as follows:

[0088] The adapter to be tested flows in, and according to the angle of the test position 3031, the lifting robot arm 101 grabs and transfers the adapter to be tested, and in the process of converting the adapter to be tested, performs a first flipping process on the adapter to be tested in a first direction; the adapter to be tested is then transferred by the conversion robot arm 102, and in the process of converting the adapter to be tested, the conversion robot arm 102 performs a second flipping process on the adapter to be tested in a second direction, and transfers the adapter to be tested that has completed the flipping process to the transfer station 402 of the transfer mechanism.

[0089] Driven by the conveying component, the transfer station 402 is transferred from the starting position 4011 of the conveying component to the position to be tested 4012. During this transfer process, the adapter to be tested on the conveying component is scanned by the scanning component to determine whether the adapter to be tested is a defective product. If it is a defective product, it is transferred to the recycling mechanism through the installation mechanism 200; if it is not a defective product, it is plugged into the test position 3031 of the aging fixture 303 one by one through the installation mechanism 200. During the process of the aging fixture 303 being transferred from the feed position 3011 of the main conveyor belt 301 to the discharge position 3012, the plugging is completed manually, and the adapter to be tested that has completed the plugging is then transferred to the discharge position 3012 through the main conveyor belt for pre-testing, and after completing the pre-testing, it enters the aging cabinet from the discharge position 3012 of the main conveyor belt 301.
