[0036] Please see attached Figure 1 and attached Figure 2 The present embodiment relates to a key test device for testing a key 100, specifically comprising an adjustment component 1, a first mechanical arm 2, a flipping mechanism 3, a second mechanical arm 4 and a detection component 5. The adjustment component 1 can make the clamping portion 110 of the key 100 face upward, and the clamping portion 110 is located on the side of the key 100 opposite to the button 120; the first mechanical arm 2 is arranged downstream of the adjustment component 1, and the first mechanical arm 2 is used to clamp the clamping portion 110; the flipping mechanism 3 is arranged downstream of the first mechanical arm 2, and the first mechanical arm 2 clamps the clamping portion 110 and moves the key 100 to the flipping mechanism 3, and the flipping mechanism 3 is used to flip the key 100; the second mechanical arm 4 and the detection component 5 are both arranged downstream of the flipping mechanism 3, and the second mechanical arm 4 moves the flipped key 100 to the position to be detected of the detection component 5, and the detection component 5 is used to perform performance detection on the key 100.

[0037] In this embodiment, the adjustment component 1 first turns over some of the keys 100. Specifically, the adjustment component 1 can adjust some of the keys 100 to a state where the clamping portion 110 faces upward and the button 120 faces downward; then the first mechanical arm 2 clamps the clamping portion 110 and places the entire key 100 on the turning mechanism 3, and the turning mechanism 3 turns the key 100 180°, that is, the key 100 is now in a state where the clamping portion 110 faces downward and the button 120 faces upward; further, the second mechanical arm 4 places the key 100 with the button 120 facing upward on the to-be-tested position of the detection component 5, and the detection component 5 is used to test the performance of the key 100. When a key 100 is tested and qualified, the process is repeated until all keys 100 are fully tested. The key testing equipment can realize complete automated operation from a series of processes including the selection, movement, flipping, loading, and detection of the keys 100, effectively avoiding manual participation and reducing labor costs, while also further improving the automation level and testing efficiency of the key 100 detection. In addition, the key testing equipment can also improve the safety and security of functional key testing, the automation level of self-production and self-inspection, and the test accuracy, and can reduce the error rate and time cost of manual mispicking, thereby reducing costs and increasing efficiency for enterprises.

[0038] Optionally, the adjustment component 1 includes a vibration table 11 , and a plurality of keys 100 to be detected are located on the vibration table 11 . The vibration table 11 can move the clamping parts 110 located on the keys 100 upwards through vibration.

[0039] In this embodiment, a vibration plate is provided on the surface of the vibration table 11, and the vibration plate is used to hold a certain number of keys 100. First, a certain number of keys 100 can be directly and randomly poured into the vibration plate. The vibration plate will keep a part of the keys 100 in a state where the clamping part 110 is facing upward through the vibration of the vibration table 11. Exemplarily, the clamping part 110 can be a part of the key 100 with a spring sheet. After the first mechanical arm 2 gradually removes the key 100 with the clamping part 110 facing upward from the vibration plate, when there is no key 100 with the clamping part 110 facing upward inside the vibration plate, the vibration table 11 can be started again to flip the remaining number of keys 100 through the vibration until all the keys 100 are removed from the vibration plate. The vibration frequency of the vibration table 11 can be adjusted according to the number of buttons 100 placed on the vibration plate and the weight of the buttons 100, and can also be verified through a preliminary test process to obtain the best vibration parameters. The vibration table 11 used in this embodiment can effectively adapt to the vibration screening of such small components as buttons 100. A conventional vibration screening table can be used for the vibration table 11, and the specific vibration generation and transmission principles will not be repeated in this application.

[0040] Furthermore, the adjustment component 1 includes a bracket 12, a vibration table 11 is arranged on the bracket 12, a visual module 13 is provided on the top of the bracket 12, and the visual module 13 is connected to the first robotic arm 2 by signal; the visual module 13 is used to obtain the image of the key 100 on the vibration table 11, and transmit the position information of the key 100 with the clamping part 110 facing upward to the first robotic arm 2.

[0041] In this embodiment, the bracket 12 is arranged on the workbench, and the bracket 12 is used to provide a limit and support function for the vibration table 11. At the same time, a visual module 13 is provided on the top of the bracket 12. The visual module 13 can directly take a picture of the vibration plate, and obtain the position coordinates of the keys 100 on each clamping part 110 according to the photo through the processor, and further control the first robotic arm 2 to accurately move and grab the corresponding key 100 according to the coordinate information through the processor.

[0042] Optionally, the flipping mechanism 3 includes a flipping plate 31 and a first driving member 32 . The first mechanical arm 2 can clamp the clamping portion 110 and move the button 100 to the flipping plate 31 . The first driving member 32 is used to drive the flipping plate 31 to flip 180°.

[0043] In this embodiment, the flipping plate 31 is a plate-shaped member with a size slightly larger than the area of ​​the key 100, the first driving member 32 is a servo rotary motor, the output end of the first driving member 32 is a rotating shaft, and the first driving member 32 can control the flipping plate 31 to flip back and forth. In this embodiment, the key 100 is placed on the flipping plate 31 through the first mechanical arm 2, and the flipping plate 31 flips 180°, so that the key 100 is flipped, that is, the key 100 should be kept in a state where the button 120 is facing upward. Of course, there are many mechanisms that can realize the flipping of the key 100, but the method of directly using the flipping plate 31 and driving it through the first driving member 32 in this embodiment is relatively direct, and there is no complicated intermediate transmission link, which can ensure the compactness of the overall structure.

[0044] Optionally, a positioning groove is provided on the turning plate 31 , and the first mechanical arm 2 can clamp the clamping portion 110 and move the button 100 into the positioning groove.

[0045] In this embodiment, the shape of the positioning groove matches the shape of the key 100. The first robotic arm 2 can clamp the clamping portion 110 and place the key 100 in the positioning groove. When the flipping plate 31 makes a flipping motion, due to the positioning effect of the positioning groove, the key 100 can be prevented from detaching from the flipping plate 31 during the flipping process, thereby ensuring the smoothness of the flipping of the key 100.

[0046] Furthermore, the key testing device also includes a conveying mechanism 6, which includes a transmission plate 61, and a limiting hole is provided on the transmission plate 61. The flipping plate 31 flips the key 100 and places it on the transmission plate 61, and the clamping part 110 is located in the limiting hole. A second driving member 62 is provided under the transmission plate 61, and the second driving member 62 is driven and connected to the clamping part 110 to drive the key 100 to move along the extension direction of the limiting hole.

[0047] In this embodiment, the transmission plate 61 extends along the transmission direction, and a strip-shaped limiting hole is opened on the transmission direction of the transmission plate 61. The flipping plate 31 flips the key 100 and places it on the transmission plate 61. At this time, the clamping part 110 extends into the limiting hole. The second driving member 62 can be a hydraulic cylinder or a linear motor. A lever is provided on the driving end of the second driving member 62, and the key 100 can be driven to slide along the limiting hole through the lever. In this embodiment, by setting a conveying mechanism 6 between the flipping mechanism 3 and the detection component 5, the length of the product detection line can be adapted, and the layout of different components in the key test device can also be convenient.

[0048] Optionally, a loading block 63 is provided at the end of the conveying plate 61 , and the button 100 can move along the conveying plate 61 to the loading block 63 , and the second robot arm 4 can move the button 100 on the loading block 63 to the detection component 5 .

[0049] In this embodiment, when the key 100 moves along the conveying plate 61, the loading block 63 ensures the final position of the key 100 and also limits the initial position of the second robotic arm 4 to extract the key 100. Therefore, the position of the key 100 can be fixed by the loading block 63, and the second robotic arm 4 can determine the exact position no longer relying on the recognition structure.

[0050] Optionally, the end of the second mechanical arm 4 includes a suction end 41 , and the suction end 41 can suction the button 100 .

[0051] In this embodiment, when the button 100 is located at the loading block 63, the button 100 is in a state where the button 120 is arranged upward, and an adsorption end 41 is provided at the end of the second robotic arm 4, and a vacuum adsorption hole is provided on the adsorption end 41. When the second robotic arm 4 is required to pick up the button 100, the vacuuming effect of the adsorption end 41 can smoothly fix the button 100, and when the button 100 is placed on the detection component 5, the adsorption end 41 can be closed to facilitate the drop of the button 100.

[0052] Optionally, the detection component 5 includes a detection platform 51 , a plurality of detection blocks 511 are disposed on the detection platform 51 , a plurality of positions to be detected are disposed on the detection blocks 511 , and the second mechanical arm 4 can place the button 100 at the position to be detected.

[0053] In this embodiment, a plurality of positions to be inspected are provided on the inspection table 51. When the key 100 has been moved to the corresponding position to be inspected by the second robotic arm 4, the keys 100 on the plurality of positions to be inspected on the same inspection block 511 can be inspected simultaneously, thereby effectively improving the inspection efficiency.

[0054] Furthermore, the detection component 5 also includes a testing mechanism 52. The detection table 51 is circular, and multiple detection blocks 511 are arranged at intervals along the circumferential direction. The testing mechanism 52 is located above the detection table 51. The detection table 51 rotates around the axis to move the detection blocks 511 to the bottom of the testing mechanism 52 in sequence. The testing mechanism 52 is used to detect the resistance, pressing force and / or stroke of the button 100.

[0055] In this embodiment, the detection table 51 is circular, and the detection table 51 is divided into a detection area every 90°. A detection block 511 is arranged in each detection area, and two positions to be detected are arranged on each detection block 511 at intervals. When the two positions to be detected on the same detection block 511 have been placed with corresponding two keys 100, the detection table 51 can be rotated around the axis to drive the detection block 511 to move to the bottom of the testing mechanism 52. The testing mechanism 52 can detect the resistance, pressing force and / or stroke of the key 100. Specifically, a cylinder is provided on the testing mechanism 52, and the working end of the cylinder can squeeze the button 120 of the key 100. At the same time, the testing mechanism 52 can further obtain whether the resistance, pressure and stroke are within the qualified range at this time.
