[0058] The assembly line of the present application has set the parameters and programs of the control system before use, and the flow of the assembly line of the present application for assembling complex mechanical products is as follows:

[0059] 1. Feeding;

[0060] The material box 6 loaded with materials and parts is moved to the upper and lower material box conveying frame 1 by a trolley, wherein each material box 6 is provided with a two-dimensional code matched with the materials in the material box 6.

[0061] 2. Material buffering and transfer;

[0062] The material box 6 is fixed and clamped by the robot 15 with clamping jaws, after stable clamping, the linear motor is started to drive the sliding table to move horizontally along the ground rail 14, and the robot 15 moves synchronously with the sliding table, so as to move the material box 6 to the buffer rack 2 for temporary storage or to the component assembly area 3 for component assembly.

[0063] The process of clamping jaw grabbing the material box 6 is as follows: the linear motor matched with the clamping jaw drives the sliders at both ends of the sliding rail 18 to relatively approach, the clamping plate 19 moves synchronously with the sliders, until the limiting protrusions on the inner sides of the two clamping plates 19 are embedded in the limiting grooves on the two sides of the material box 6, at this time the material box 6 is stably clamped and fixed; when it is needed to release the clamping and limiting of the material box 6 by the clamping jaw, the linear motor matched with the clamping jaw is reversed.

[0064] 3. Component assembly;

[0065] The material box 6 moved to the component assembly area 3 is subjected to component assembly, the component assembly area 3 is used for completing the assembly, gluing, marking, detection and automatic assembly of sealing rings and leather cups of product components, and the assembled material is transferred to the component supermarket 4, the component supermarket 4 is used for storing product components which have completed component operation and components which need to be cured after gluing, the material box 6 for storing product components is arranged in the component supermarket 4, and the two-dimensional code corresponding to each product component is arranged on the material box 6.

[0066] 4. Whole machine assembly;

[0067] First, the shell of the complex mechanical product is fixed on the six-face rotating tool 13, and then the remaining components are assembled to the shell in the assembly sequence. The product components placed in the material box 6 in the component supermarket 4 are transferred to the conveying line body 12 through the ground rail 14 and the robot 15 with clamping jaws, and the material box 6 loaded with product components moves with the conveying line body 12, first entering the head docking station 7, then flowing through each assembly station 11 of the whole machine assembly area 5, the automatic measurement station 10, the 3D scanning station 9, and finally flowing out of the tail docking station 8. The whole machine assembly area 5 is used to complete the assembly, measurement, 3D scanning and appearance detection of the product.

[0068] During the assembly process of each assembly station 11 in the component assembly area 3 and the whole machine assembly area 5, the display screen of each assembly station 11 will display the assembly process, the parts, tools and torque required for each step, and the station itself will also be lighted to guide the staff to operate.

[0069] For example, when the current assembly step needs to take a certain part, the drawer 16 storing the target part will be automatically pulled out and opened under the action of the telescopic rod, and at the same time the lamp panel on the top of the assembly station 11 will emit a "cross" laser to the target part in the corresponding grid, guiding the staff to take the correct part. After the target part is taken, the pressure sensor senses that the target part has been taken, and the telescopic rod drives the drawer 16 to retract and reset.

The six-face rotating tool 13 drives the special-shaped support 25 to rotate in the vertical plane through the first motor 24, and drives the fixed support to rotate in the plane perpendicular to the vertical plane through the second motor 26, so as to adjust the orientation of each face of the complex mechanical product shell according to the needs, and facilitate the assembly.

[0073] The six-surface rotating tool 13 is fixedly connected with the carrier plate through the base 23, the carrier plate flows with the conveying line body 12, and the six-surface rotating tool 13 needs to be powered first when flowing to each station. The power connection process is as follows: first, set the target station of the six-surface rotating tool 13, the target station detects whether the six-surface rotating tool 13 approaches the target position through a proximity switch, after the proximity switch detects the six-surface rotating tool 13, the stop cylinder of the target station is started to stop the carrier plate loaded with the six-surface rotating tool 13, and then the lifting positioning mechanism 27 is started, the lifting positioning mechanism 27 drives the electric plug to move upward and is flexibly inserted into the socket at the bottom of the carrier plate through the spring.
