[0002] During the manufacturing process of mobile phone buttons, a comprehensive inspection of their appearance is required, meaning that multiple surfaces of the buttons need to be inspected to improve the pass rate. Existing mobile phone button appearance inspection equipment is generally customized according to the inspection types of multiple surfaces of the buttons, possessing the function of inspecting specific button surfaces. For example, inspecting six surfaces of a mobile phone button requires six customized inspection devices with corresponding inspection functions. Furthermore, the inspection process necessitates multiple transfers of the mobile phone buttons between these inspection devices, resulting in low inspection efficiency.

[0003] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0054] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0055] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0056] In this application, the term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of only one centrifugal vortex magnetic pump, the simultaneous existence of one centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, or the existence of only one centrifugal vortex magnetic pump. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0057] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0058] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0059] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0060] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0061] Please see Figures 1 to 7 This embodiment provides a mobile phone button appearance inspection device, which includes a frame 1, multiple inspection mechanisms, a feeding mechanism 2, a discharging mechanism 3, a transfer mechanism 4, a first conveying mechanism 5, and a second conveying mechanism (not shown in the figure).

[0062] Multiple inspection mechanisms are arranged along a preset direction on the frame 1, forming an inspection channel 70. These mechanisms are used to inspect multiple surfaces of the mobile phone buttons. A feeding mechanism 2 is mounted on the frame 1 and configured to supply the mobile phone buttons to the uppermost part of the inspection channel 70. A discharging mechanism 3 is mounted on the frame 1 and configured to collect and / or output the mobile phone buttons from the lowermost part of the inspection channel 70. A transfer mechanism 4 is mounted on the frame 1 and located within the inspection channel 70, configured to carry and rotate the mobile phone buttons. A first conveying mechanism 5 is mounted on the frame 1 and located upstream of the transfer mechanism 4, configured to pick up and transport the mobile phone buttons supplied by the feeding mechanism 2 to the transfer mechanism 4. A second conveying mechanism is mounted on the frame 1 and located downstream of the transfer mechanism 4, configured to pick up and transport the mobile phone buttons from the transfer mechanism 4 to the discharging mechanism 3.

[0063] In actual testing, the feeding mechanism 2 first supplies the mobile phone button to the uppermost part of the testing channel 70. Then, the first conveying mechanism 5 picks up and transports the mobile phone button supplied by the feeding mechanism 2 until it is transported to the transfer mechanism 4. At the same time, some testing mechanisms inspect some surfaces of the mobile phone button. Then, the transfer mechanism 4 carries and rotates the mobile phone button. The second conveying mechanism picks up and transports the mobile phone button on the transfer mechanism 4 until it is transported to the unloading mechanism 3. At the same time, the remaining testing mechanisms inspect the remaining surfaces of the mobile phone button. This completes the inspection of all surfaces of the mobile phone button. Finally, the unloading mechanism 3 collects and / or outputs the mobile phone button at the lowermost end of the testing channel 70.

[0064] This setup allows a single testing device to inspect multiple surfaces of the phone's buttons, eliminating the need to move the buttons between multiple devices and thus improving testing efficiency. It also avoids damage such as bumps and scratches to the buttons during transport. Furthermore, sequentially inspecting multiple surfaces of the phone buttons while transporting them further enhances testing efficiency.

[0065] It should be noted that the unloading mechanism 3 can adopt the loading and conveying mechanism in the next process, which can improve the efficiency of mobile phone button handling, and will not be described in detail here. Of course, in other embodiments, the unloading mechanism 3 can also adopt other existing structures with functions such as collection and screening, and no specific requirements or limitations are made for this.

[0066] To further improve testing efficiency, the feeding mechanism 2 includes a moving part 21 and a feeding gripper 22. The moving part 21 slides along a preset direction on the frame 1. The feeding gripper 22 is mounted on the moving part 21 and can move up and down, and can grip two rows of mobile phone buttons. It is understood that the feeding gripper 22 can grip two rows of mobile phone buttons, thus enabling simultaneous feeding of two rows of buttons, thereby improving the testing efficiency of the mobile phone buttons.

[0067] Correspondingly, the first conveying mechanism 5 includes a first conveying component (not shown in the figure) and two first gripping components 51. The first conveying component is slidably mounted on the frame 1 along a preset direction. Both first gripping components 51 are mounted on the first conveying component, and both first gripping components 51 are capable of rising and falling, with each first gripping component 51 capable of gripping a row of mobile phone buttons.

[0068] Similarly, the second conveying mechanism includes a second conveying component and two second gripping components. The second conveying component is slidably mounted on the frame 1 along a preset direction. Both second gripping components are mounted on the second conveying component, and both second gripping components are capable of rising and falling, with each second gripping component capable of gripping a row of mobile phone buttons.

[0069] With this configuration, both the first conveying mechanism 5 and the second conveying mechanism can simultaneously transport two rows of mobile phone buttons. In this embodiment, one row of mobile phone buttons contains 8 buttons, and two rows contain 16 buttons. Of course, in other embodiments, the design can be tailored to the actual application scenario, such as setting the mobile phone buttons to 3, 4, or more rows, with corresponding settings for the loading gripper 22, the first gripper 51, and the second gripper. This embodiment does not impose specific requirements or limitations in this regard. It should be noted that the loading gripper 22, the first gripper 51, and the second gripper are all selected from existing vacuum suction heads with lifting functions. For example, the first gripper 51 has a row of vacuum suction cups arranged in a preset direction.

[0070] It is understandable that the phone buttons may shift during the loading process, causing deviations in the detection positions of multiple inspection mechanisms and thus affecting the accuracy of the inspection results. Therefore, to address this issue, the phone button appearance inspection equipment also includes an alignment mechanism 6. The alignment mechanism 6 is mounted on the frame 1 and located between the loading mechanism 2 and the first conveying mechanism 5. The alignment mechanism 6 is configured to align the two rows of phone buttons supplied by the loading mechanism 2. This configuration ensures the alignment of the phone buttons during the inspection process, guaranteeing the accuracy of the inspection results.

[0071] Specifically, the alignment mechanism 6 includes a base component 61, a pusher component 62, and a drive component 63. The base component 61 is mounted on the frame 1 and has adjustment holes 611. The cross-section of the adjustment holes 611 is tapered, and the smallest side of the adjustment holes 611 can fit and conform to the mobile phone buttons. Two rows of adjustment holes 611 are arranged corresponding to the mobile phone buttons, and multiple adjustment holes 611 can correspond one-to-one with multiple mobile phone buttons. The pusher component 62 is slidably mounted on the base component 61, extending into the adjustment holes 611 and capable of pushing the mobile phone buttons to the smallest side of the adjustment holes 611. The number of pusher components 62 corresponds to the number of adjustment holes 611. The drive component 63 is mounted on the base component 61 and is configured to drive all the pusher components 62 to slide synchronously.

[0072] It should be noted that the driving component 63 is selected as a cylinder in the prior art, and all the pushing components 62 are connected to the telescopic end of the cylinder. In other embodiments, the driving component 63 can also be any other linear drive mechanism in the prior art, such as a linear module, an electric cylinder, etc.

[0073] In practical applications, the feeding mechanism 2 first places the two rows of mobile phone buttons into the two rows of adjustment holes 611 one by one. Then, the driving component 63 drives multiple pushing components 62 to move, so that each pushing component 62 can push its corresponding mobile phone button to slide to the smallest side of the adjustment hole 611. This achieves the positioning of the two rows of mobile phone buttons. Finally, the first conveying mechanism 5 picks up and transports the two rows of mobile phone buttons.

[0074] In this embodiment, the mobile phone button is elongated, therefore, multiple testing agencies need to test all six sides of the mobile phone button.

[0075] Specifically, one of the multiple testing mechanisms is a back-side inspection camera module 80, which is located below the loading gripper 22 to inspect the back of the phone button when the loading gripper 22 transports the phone button.

[0076] Furthermore, four of the multiple detection mechanisms are first side detection camera modules 81. These four first side detection camera modules 81 are configured corresponding to the first transport mechanism 5 to detect the two opposite sides of the phone button when the first transport mechanism 5 transports the phone button. In this embodiment, two first side detection camera modules 81 are configured corresponding to one first gripper 51. The two first side detection camera modules 81 are located on opposite sides of the same first gripper 51; that is, two first side detection camera modules 81 form a group, and the two first side detection camera modules 81 in the same group are used to detect the two long sides of the phone button.

[0077] Accordingly, four of the multiple detection mechanisms are second side detection camera modules 82. These four second side detection camera modules 82 are configured corresponding to the second transport mechanism to detect the two opposite sides of the phone button when the second transport mechanism transports the phone button. In this embodiment, two second side detection camera modules 82 are configured corresponding to one second gripper. The two second side detection camera modules 82 are located on opposite sides of the same second gripper; that is, two second side detection camera modules 82 form a group, and the two second side detection camera modules 82 in the same group are used to detect the two short sides of the phone button.

[0078] Furthermore, at least two of the multiple inspection mechanisms are front-facing inspection camera modules 83, which are located above the first transport mechanism 5 and / or the second transport mechanism to inspect the front of the mobile phone button when the first transport mechanism 5 and / or the second transport mechanism transport the mobile phone button.

[0079] It should be noted that in this embodiment, four front detection camera modules 83 are set, two of which are set above the two second grippers and the other two are set above the two first grippers 51, so that the front of the mobile phone buttons can be detected twice, thereby helping to improve the accuracy of the detection results.

[0080] It should also be noted that in this embodiment, the back detection camera module 80, the first side detection camera module 81, the second side detection camera module 82, and the front detection camera module 83 have the same structure. The following description uses the front detection camera module 83 as an example. The front detection camera module 83 includes a flying camera and an LED light. The flying camera is used to capture images of the front of the phone's buttons, and the LED light is used to illuminate the front of the phone's buttons. It is worth noting that the flying camera is existing technology and can capture images of a specific feature during movement. This embodiment does not make any improvements to the specific structure and working principle of the flying camera, so it will not be described in detail here.

[0081] To facilitate the arrangement of multiple testing units, the testing process requires the two rows of mobile phone buttons to be rotated one by one. In this embodiment, a transfer mechanism 4 is used to rotate the two rows of mobile phone buttons one by one. In addition, in this embodiment, the rotation angle of the mobile phone buttons is 90°.

[0082] Specifically, the transfer mechanism 4 includes a transfer platform (not shown in the figure), a first transfer component 41, a second transfer component (not shown in the figure), multiple first rotating grippers 42, and multiple second rotating grippers (not shown in the figure). The transfer platform is mounted on the frame 1 and is configured to support two rows of mobile phone buttons. Both the first transfer component 41 and the second transfer component are vertically slidable on the frame 1. Multiple first rotating grippers 42 are arranged in a row on the first transfer component 41, each corresponding to one row of mobile phone buttons. Each first rotating gripper 42 is configured to grip and rotate its corresponding mobile phone button. Multiple second rotating grippers are arranged in a row on the second transfer component, each corresponding to one row of mobile phone buttons. Each second rotating gripper is configured to grip and rotate its corresponding mobile phone button. It should be noted that the transfer platform is provided with two rows of cross slots capable of supporting the mobile phone buttons before or after rotation.

[0083] In the actual testing process, the first conveying mechanism 5 first transports two rows of mobile phone buttons to the transfer platform. Then, the first transfer component 41 and the second transfer component both descend vertically. Next, multiple first rotating grippers 42 and multiple second rotating grippers grab the corresponding mobile phone buttons. Then, the first transfer component 41 and the second transfer component both rise vertically. Then, multiple first rotating grippers 42 and multiple second rotating grippers rotate the corresponding mobile phone buttons. Then, the first transfer component 41 and the second transfer component both descend vertically. Then, multiple first rotating grippers 42 and multiple second rotating grippers release the corresponding mobile phone buttons, so that the two rows of mobile phone buttons are placed on the transfer platform. Finally, the second conveying mechanism grabs and transports the two rows of mobile phone buttons that have been rotated on the transfer platform.

[0084] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
