Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1-12 As shown, the present invention provides a watch case size measurement and appearance inspection device, including a workbench 100, which is provided with a material loading station, a wall thickness measurement station 400, a thickness measurement station 500, a water guide hole inspection station, a sharp edge inspection station, a barcode scanning station, a plate display station, and a material unloading station.

[0038] The loading station is equipped with a loading mechanism 200 and a loading robot 201. The loading mechanism 200 includes a conventional material tray loading bin 202 and an empty material tray unloading bin 203. The material tray loading bin 202 and the empty material tray unloading bin 203 are arranged side by side. The structure of the empty material tray unloading bin 203 is the same as that of the material tray loading bin 202. Both the material tray loading bin 202 and the empty material tray unloading bin 203 include a frame 2021, a tray, and a lifting drive component 2024 for driving the tray to move upward. The difference between the material tray loading bin 202 and the empty material tray unloading bin 203 is that the lifting drive component 2024 rotates in opposite directions, and the frame 2021 is equipped with a tool for positioning the material tray. The tray positioning component includes a tray positioning cylinder 2023 and a tray positioning block 2022. The tray positioning cylinder 2023 is connected to the tray positioning block 2022 to drive the tray positioning block 2022 to move back and forth. The lifting drive component 2024 includes a conventional drive motor and a lead screw lifting module. When the drive motor is working, its output shaft drives the lead screw to rotate. Since the thread on the lead screw and the spiral groove in the nut mesh with each other, the nut will move up and down along the axial direction of the lead screw, thereby driving the tray to lift and lower. By changing the rotation direction of the drive motor, the rotation direction of the lead screw can be controlled, thereby controlling the lifting and lowering direction of the tray.

[0039] The feeding manipulator 201 is a conventional technology, and the feeding manipulator 201 is provided with a tray clamping assembly for clamping the tray and a product clamping assembly for clamping the product on the tray. The tray clamping assembly comprises a tray clamping arm 2013, a clamping arm driving cylinder 2012, a clamping arm lifting plate 2014 and a clamping arm lifting cylinder 2011. The clamping arm driving cylinder 2012 is connected with the tray clamping arm 2013 and drives the tray clamping arm 2013 to open or close. The clamping arm lifting cylinder 2011 is connected with the clamping arm lifting plate 2014 and drives the clamping arm lifting plate 2014 to lift and descend, and makes the clamping arm lifting plate 2014 drive the clamping arm driving cylinder 2012 and the tray clamping arm 2013 to lift and descend synchronously. The product clamping assembly comprises a variable distance cylinder 2015, a variable distance track 2017 and a plurality of variable distance sliders and feeding clamps 2019. The number of the variable distance sliders corresponds to the number of the positioning jigs 3051. The plurality of variable distance sliders are arranged on the variable distance track 2017 at intervals and are in sliding fit with the variable distance track 2017. Each variable distance slider is provided with a mounting seat 2016. The mounting seat 2016 is provided with a clamp driving cylinder 2018. The clamp driving cylinder 2018 is connected with the feeding clamp 2019 and drives the feeding clamp 2019 to open or close. The variable distance cylinder 2015 is connected with the outermost variable distance slider and drives it to move, and makes the variable distance slider drive other variable distance sliders to move. Specifically, the variable distance cylinder 2015 drives the variable distance slider to move to the outer end direction, and the plurality of variable distance sliders are in an open state, and the distance between the adjacent two feeding clamps 2019 is increased. Conversely, the variable distance cylinder 2015 drives the variable distance slider to move to the inner end direction, and the plurality of variable distance sliders are in a retracted state, and the distance between the adjacent two feeding clamps 2019 is decreased. Since the subsequent detection action and measurement action need to be considered, the distance between the positioning jigs 3051 is designed to be larger than the distance between the tray grooves. By setting the clamp with the variable distance function, the tray and the positioning jigs 3051 can be better matched;
