The loading mechanism 200 includes a tray upper bin 202 and an empty tray lower bin 203 of conventional technology. The tray upper bin 202 and the empty tray lower bin 203 are arranged side by side. The structure of the empty tray lower bin 203 is the same as that of the tray upper bin 202. The tray upper bin 202 and the empty tray lower bin 203 both include a frame 2021, a tray and a lifting drive component 2024 for driving the tray to move upward. The difference between the tray upper bin 202 and the empty tray lower bin is that the rotation directions of the lifting drive component 2024 are opposite, and the frame 2021 is equipped with a device for positioning the 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 forward and backward. The lifting drive component 2024 includes a driving motor and a screw lifting module of conventional technology. When the driving motor is working, its output shaft drives the screw to rotate. Since the thread on the screw and the spiral groove in the nut are engaged with each other, the nut will move up and down along the axial direction of the screw, thereby driving the tray to move up and down. By changing the rotation direction of the driving motor, the rotation direction of the screw can be controlled, and then the lifting direction of the tray can be controlled;

[0039] The feeding robot 201 is a conventional technology. The feeding robot 201 is equipped 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 includes 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 to the tray clamping arm 2013 and drives the tray clamping arm 2013 to open or close.

Specifically, the variable pitch cylinder 2015 drives the variable pitch slider to move toward the outer end, and multiple variable pitch sliders are stretched. In the open state, the distance between two adjacent feeding clamps 2019 becomes larger. On the contrary, the variable pitch cylinder 2015 drives the variable pitch slider to move inward, and multiple variable pitch sliders are in the inward state, and the distance between two adjacent feeding clamps 2019 becomes smaller. Since it is necessary to take into account the subsequent detection action and measurement action, the distance between the positioning fixture 3051 will be designed to be larger than the distance between the material tray and the material trough. By setting a fixture with a variable pitch function, the material tray and the positioning fixture 3051 can be better matched;

[0068] After the rotating clamping assembly 304 places the product on the limiting plate 603, the rotating driving module drives the rotating disk to rotate and rotates the product to the first detection position. The linear driving component 701 drives the linear slide 703 to move, and the linear slide 703 drives the CCD camera 705 to move. During the movement, the CCD camera 705 detects the water guide hole of each product to detect whether the water guide hole of the watch case is blocked. Moreover, when the CCD camera 705 moves to the front side of a certain limiting plate 603, the corresponding lifting and pushing component 604 drives the limiting plate 603 to rise to facilitate the CCD camera 705 to detect. After completing the water guide hole detection action, the rotating driving module drives the rotating disk to rotate, and the rotating disk drives the product that has completed the water guide hole detection action to rotate to the second detection position.

The two-dimensional code scanner 904 scans the two-dimensional code on each watch case during the movement to record information. After completing the sharp edge detection and scanning action, the rotary drive module drives the rotating disk to rotate, and rotates the product that has completed the sharp edge detection and scanning action to the unloading position. After the handling robot clamps the product away, the rotary drive module drives the rotating disk to rotate to the loading position, and the rotary clamping assembly 304 places the product that has completed the thickness measurement action on the limit plate 603, and repeats the above steps. This method has a high degree of automation and can effectively improve the overall work efficiency of the watch case size measurement.

When the product is full, the first driving component 1005 drives the upper slide 1002 to move, and the upper slide 1002 drives the first turnover plate 1001 to move backward. The second driving component 1007 drives the lower slide 1006 to move, and the lower slide 1006 drives the second turnover plate 1004 to move forward. Since the first turnover plate 1001 and the second turnover plate 1004 are arranged in the upper and lower layers, they move without interfering with each other. The plate placing robot 2100 grabs the product and places it on the second turnover plate 1004. At this time, the unloading robot 2200 drives the product clamping component to move To the top of the first turntable 1001, the clamping arm driving body 2201 drives the product clamping arm 2202 to close to clamp the product, and then the unloading robot 2200 drives the product clamping component to move to the corresponding product unloading bin or defective product unloading bin. After the tray of the product unloading bin or defective product unloading bin is placed on the plate, the lifting driving component 2024 of the product unloading bin or defective product unloading bin drives the tray to descend an empty position, and the unloading robot 2200 drives the empty tray clamping assembly to move to the empty tray upper bin 202, and the claw driving module 2205 drives The tray clamp 2204 closes to clamp the empty tray, and the unloading robot 2200 drives the empty tray clamping assembly to move to the product unloading bin or above the defective product unloading bin that needs to be replenished with the empty tray. At the same time, the lifting drive component 2024 in the empty tray upper bin 202 drives the tray to rise to drive a new empty tray to rise one empty position, and repeat the above steps to realize automatic sorting of good products and different types of defective products. The different types of defective products are wall thickness measurement defective products, thickness measurement defective products, sharp edge detection defective products and water guide hole detection defective products.

[0071] Compared with the traditional technology: by integrating the wall thickness measuring mechanism 401, the thickness measuring mechanism, the water guide hole detection mechanism 700 and the sharp edge detection mechanism on the workbench 100, the equipment can measure the thickness of the case, measure the thickness of the "hole of the bar" of the case, detect whether the water guide hole of the case is blocked, and detect whether the installation groove of the case strap has a sharp edge. Only one mechanical equipment is needed to complete the above-mentioned measurement and detection functions, which can reduce the floor space of the equipment on the one hand, and greatly improve the overall work efficiency of the case size measurement and detection on the other hand. The setting of the product handling mechanism 300 and the product turnover mechanism 600 can greatly enhance the connectivity of the wall thickness measuring mechanism 401, the thickness measuring mechanism, the water guide hole detection mechanism 700, the sharp edge detection mechanism, and the code scanning mechanism 900, and further improve the overall work efficiency of the case size measurement. The setting of the plate placing mechanism 1000 can realize the automatic sorting of good and bad products, which can save the manual sorting workflow on the one hand, and effectively improve the overall work efficiency of the case size measurement on the other hand.
