Description

Technical Field

[0001] The present application relates to the technical field of automated control, and in particular to a precise testing mechanism for a watch screen module. Background Art

[0002] Before assembling a watch, the quality of the watch parts to be assembled needs to be evaluated, and parts such as the watch battery, watch screen and watch case need to be tested.

[0003] The existing technology usually uses a semi-automatic form to inspect the watch screen. The staff manually places the watch screen at the specified position of the inspection station and aligns the position of the watch screen. Then, a special inspection equipment is used to inspect the appearance of the watch screen and the interface chip of the cable electrically connected to the watch screen to check whether the interface chip of the cable can be normally connected to the main control chip of the watch, thereby completing the inspection of the quality of the watch screen. When the staff manually moves the watch screen, it is easy to drive the surrounding air, causing dust and other impurities to fall on the watch screen, affecting the quality of the watch screen. Moreover, when the watch is mass-produced, a higher labor cost is required, and the inspection efficiency of the watch screen is relatively low, so it needs to be improved. Utility Model Content

[0004] In order to reduce the frequency of manual operations performed by staff during quality inspection of watch screens and improve the efficiency of inspection of watch screen modules, the present application provides a precise testing mechanism for watch screen modules.

[0005] The watch screen module precision testing mechanism provided in this application adopts the following technical solution:

[0006] A watch screen module precision testing mechanism comprises a frame, and an alignment platform and a detection station which are sequentially arranged on the frame, wherein the alignment platform is movably connected to the upper surface of the frame, and the alignment platform can slide back and forth on the upper surface of the frame; an alignment camera is arranged on one side of the frame, and the image acquisition end of the alignment camera faces the upper surface of the alignment platform; the mechanism also comprises a transport component, which is used to transport the material to be tested to the alignment platform or the upper surface of the detection station; the mechanism also comprises a detection component, which is arranged at the detection station and is used to detect whether the watch screen cable can be electrically connected to an external chip.

[0007] By adopting the above technical solution, when inspecting the watch screen, the watch screen to be inspected is placed on the upper surface of the alignment platform; the alignment camera collects the image of the watch screen, and the alignment platform adjusts the position of the alignment platform according to the position information of the mobile phone screen in the image collected by the alignment camera, thereby adjusting the placement orientation of the watch screen; the transportation component can move the aligned watch screen from the upper surface of the alignment platform to the inspection station, and the inspection component can automatically inspect the quality of the watch screen and the cable, thereby reducing the frequency of manual operations of the staff during the quality inspection of the watch screen and improving the efficiency of the inspection of the watch screen module.

[0008] Optionally, a first vacuum adsorption component is embedded on both the alignment platform and the detection station, and the first vacuum adsorption component is used to limit and fix the watch screen, and the first vacuum adsorption component is connected to a power supply.

[0009] By adopting the above technical solution, the first vacuum adsorption component can limit and fix the watch screen. When the watch screen is placed on the alignment platform (or detection station), the first vacuum adsorption component is energized. When the first vacuum adsorption component is energized, it can adsorb the watch screen, thereby limiting and fixing the watch screen and the alignment platform (or detection station), reducing the possibility of displacement of the watch screen due to external force.

[0010] Optionally, the alignment platform and the inspection station are distributed in sequence along the length direction of the frame, and the transport assembly includes a slide rail and a transport arm, the slide rail is arranged on the upper surface of the frame, and the length direction of the slide rail is consistent with the length direction of the frame; the transport arm is movably connected to the slide rail, and the transport arm can slide back and forth along the length direction of the slide rail, and the transport arm is used to move the watch screen.

[0011] By adopting the above technical solution, the transport arm can fix and move the watch screen. When the transport arm slides back and forth along the length direction of the slide rail, it can drive the watch screen to move between the alignment platform and the inspection station, thereby realizing the transportation of the watch screen.

[0012] Optionally, the carrying arm includes a support seat, a telescopic cylinder, a support plate and a suction cup, the support seat is slidably connected to the slide rail, and the support seat can slide back and forth along the length direction of the slide rail; the telescopic cylinder is arranged on a side of the side wall of the support seat close to the detection station, the base of the telescopic cylinder is fixedly connected to the side wall of the support seat, and the output end of the telescopic cylinder extends toward the ground; the support plate is fixedly connected to the output end of the telescopic cylinder, and the support plate is parallel to the upper surface of the detection station; the suction cup is connected to a power supply, and the suction cup is arranged on a side of the support plate close to the detection station.

[0013] By adopting the above technical scheme, the specific structure of the transport arm is clarified, and the telescopic cylinder can pull the suction cup to move back and forth in the direction close to or away from the upper surface of the alignment platform (or detection station); when transferring the watch screen from the alignment platform to the detection station, first control the support seat to move to the alignment platform, and the telescopic cylinder pulls the suction cup to move in the direction close to the upper surface of the alignment platform until the suction cup abuts against the watch screen to be detected; the suction cup is energized so that the watch screen can be adsorbed on the suction cup, and then the support seat is controlled to move along the slide rail to the detection station, so that the watch screen stops directly above the detection station; the suction cup and the watch screen are controlled to move in the direction close to the upper surface of the detection station and the suction cup is controlled to be powered off, so that the watch screen falls on the detection station, thereby realizing automatic transfer of the watch screen.

[0014] Optionally, a plurality of the inspection stations are provided, and the plurality of the inspection stations are evenly distributed along the length direction of the frame.

[0015] By adopting the above technical solution and setting up multiple inspection stations, the watch screen module precision testing mechanism can inspect multiple watch screens at the same time, thereby improving the inspection efficiency of the watch screen module precision testing mechanism.

[0016] Optionally, it also includes a flip component, which is communicatively connected to the alignment camera; the flip component is used to adjust the front and back sides of the watch screen on the alignment platform.

[0017] By adopting the above technical solution, the alignment camera can control the opening and closing of the flip component. When the watch screen is placed on the alignment platform, there is a possibility that the connecting pins of the cable are hidden between the cable and the alignment platform due to the watch screen being placed upside down, making it possible that the detection component cannot automatically contact the connecting pins of the cable; the flip component can adjust the front and back sides of the watch screen on the alignment platform, so that when the transport component transfers the watch screen to the detection station, the connecting pins of the cable can be exposed to the detection component, so as to facilitate the detection of the watch screen by the detection component.

[0018] Optionally, the flip assembly includes a flap and a driving member, the flap having an open state and a closed state when in use, the driving member being used to drive the flap to switch back and forth between the open state and the closed state, and when the flap is in the closed state, the flap and the alignment platform are stacked; a second vacuum suction member is provided on the flap, and the second vacuum suction member is used to limit and fix the watch screen, and the second vacuum suction member is connected to a power supply, and when the flap is in the closed state, the second vacuum suction member is located between the flap and the upper surface of the alignment platform.

[0019] By adopting the above technical solution, the driving component can drive the flap to switch back and forth between the open state and the closed state. When the watch screen is turned upside down, the flap is controlled to move toward the direction of the alignment platform; the watch screen is adsorbed by the second vacuum adsorption component, so that the watch screen can be flipped together with the flap, so that the end of the watch screen cable with the connecting pin faces upward; subsequently, it is only necessary to control the transport arm to move to the flap and transfer the watch screen directly to the inspection station, so as to facilitate the convenience of the inspection component in subsequent inspection of the watch screen.

[0020] Optionally, the driving member includes a rotating shaft, a bracket and a driving motor, the bracket is arranged on the upper surface of the frame, and two mounting plates are protruded from the side of the bracket away from the upper surface of the frame; the two ends of the rotating shaft in the length direction are respectively penetrated and rotatably connected to the two mounting plates, the length direction of the rotating shaft is consistent with the length direction of the alignment platform, a connecting part is protruded from one side of the flap, and the connecting part is fixedly connected to the rotating shaft; the base of the driving motor is fixedly connected to the upper surface of the frame, and the output shaft of the driving motor is coaxially fixed to the rotating shaft.

[0021] By adopting the above technical solution, the driving motor can drive the rotating shaft to rotate circumferentially around the axis of the rotating shaft when working, thereby driving the flap to rotate circumferentially around the axis of the rotating shaft, thereby realizing the adjustment of the flap state.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The watch screen to be inspected is placed on the upper surface of the alignment platform; the alignment camera collects the image of the watch screen and adjusts the position of the alignment platform, and adjusts the placement of the watch screen to facilitate the subsequent inspection of the watch screen quality by the inspection component; the transportation component can move the aligned watch screen from the upper surface of the alignment platform to the inspection station, and the inspection component automatically inspects the quality of the watch screen and the cable, reducing the frequency of manual operations of staff during the quality inspection of the watch screen and improving the efficiency of the inspection of the watch screen module.
