[0111] Embodiment 9:

[0112] like Figure 1-9 As shown, the following is the operating principle of the assembled finished product detection machine of the present invention:

[0113] The tray transporting robot 600 transports the assembled finished product [the finished product after the camera frame and the lens are assembled] from the belt conveyor line 700 to the pre-push firmness detection mechanism 200. The pre-push firmness detection mechanism 200 detects the assembly firmness. After the detection, the pre-push component product placement platform 2 is pushed out, and the tray transporting robot 600 transports the pre-pushed and tested product tray to the transfer platform.

[0114] The two groups of robot assemblies are the first robot assembly and the second robot assembly on the left. The first robot assembly is used to move the pre-pushed inspection 0K products to the transfer platform, and the second robot assembly is used to move the pre-pushed inspection 0K products and the material tray on the transfer platform to the height offset detection mechanism 500.

[0115] The transfer platform includes a fixed transfer platform and a mobile transfer platform. The fixed transfer platform is used to store the material trays. The finished products after inspection are classified and automatically compensated by the sorting robot. The mobile transfer platform can be moved by the sorting robot.

[0116] The sorting and tray changing robot mechanism 400 moves the sorting robot in the Y direction, and the sorting robot on it moves the tray to the fixed transfer platform to classify and automatically compensate the products. The sorting robot moves the tray of 0K products after compensation and pre-pushing detection to the mobile transfer platform.

[0117] The mobile transfer platform runs the full tray of 0K products for pre-push inspection to the tray handling robot [i.e., the second robot assembly], and the tray handling robot transports the pre-pushed 0K products to the height offset detection platform [i.e., the tray placement platform 8] on the height offset detection mechanism 500. The height offset detection moves in the Y direction of the tray of pre-pushed 0K products, and performs height offset detection on the assembled finished products. After the detection, the height offset detection platform [i.e., the tray placement platform 8] moves in the Y direction again, runs to the bottom of the sorting robot, and transports its tray to the fixed sorting platform.

[0118] After the sorting robot sorts and automatically compensates for the height deviation detection 0K and NG, the sorting robot transports the tray full of height deviation detection 0K products to the mobile transfer platform, and the mobile transfer platform carries the 0K products to the discharging robot.

[0119] The unloading robot moves the tray containing 0K products to the unloading platform, and the unloading platform moves the detected 0K products to the plasma cleaning area for cleaning and unloading.

[0120] The high-precision assembly inspection and sorting machine for optical devices is mainly used for the inspection of the firmness of the frame and lens of the camera lens after assembly, the inspection of the assembly height offset, and the classification of the finished products with different assembly conditions and automatic compensation to the corresponding trays. The whole process is completed automatically by various mechanical components. According to the above requirements, this high-precision assembly inspection and sorting machine for optical devices is equipped with a pre-push component structure to measure the firmness of the combination of the lens and the frame structure by detecting the deformation of the lens after assembly. In order to ensure the interchangeability of the specifications of the assembled finished products and subsequent use, a height displacement deviation detection structure is also set up. In order to distinguish different situations of firmness and height deviation inspection, different types of automatic throwing bins and replenishing bins are set up. The robot has the function of transporting the tray and transporting the single assembled finished products of the sorted products to the designated tray.

[0121] When using the mechanism of the present invention, both the pre-push firmness detection component and the height displacement deviation detection component use marble as the installation base plate, which makes the entire detection process stable; the pre-push firmness detection component is provided with the function of cleaning the pre-push head to ensure the cleanliness of the product firmness detection. The push head moves up and down by using a low-friction cylinder plus a guide rail slider to drive the push head up and down, ensuring the stable balance of the push head pushing the product into the correction plate, and the force sensor is used to detect the thrust of the cylinder at all times. When the thrust is constant, the upper ball head displacement sensor is lowered to contact the lens to detect the displacement deformation, and the detection accuracy reaches ±3μm. The detection platform for the assembly offset of the finished frame and lens adopts a double tray placement structure, and the vacuum structure for adsorbing the product and the tray is independently set, and a mechanism for automatically correcting the tray is provided. The detection mechanism uses two sets of linear laser sensors to detect the height of any four points of the frame and lens of each finished product, and then transmits the data to the system to quickly calculate the offset. The scanning head of the linear sensor detects while moving, with a detection accuracy of ±2.5μm; this optical device high-precision assembly detection deviation calculation mechanism can quickly, stably and accurately detect the assembly height deviation calculation of the frame and lens of the assembled finished product. The manipulator has the functions of calibrating, sorting products, and transporting trays; it is equipped with multiple groups of silos to classify products with different assembly effects and load them into designated trays. This invention mechanism has complete detection functions and high precision. Different products are loaded into designated trays, which greatly improves production efficiency and reflects the use of the interchangeability of the assembled finished products. The whole process is automatically detected and calculated, which reduces the production of finished products and replaces the detection that cannot be completed manually.

[0122] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
