This is a key functional and appearance requirement.

[0003] On the production line of multi-seat airline seats, a certain process involves adjusting the preset angles and consistency of multiple dining tables when they are unfolded. As the operator sequentially adjusts the inclination angles of the seat's multiple dining tables, they need to visually observe the changes in the angles and then use a spirit level to measure them.

[0033] As a preferred embodiment, the trigger sensitivity of the torque sensor 340 is less than 0.1N. In the civil aviation seat assembly line, a collaborative robot is used to integrate adjustment tooling and sensors to achieve human-machine collaboration in the seat production line to assemble and adjust the preset angles and consistency requirements of the dining table of the multi-seat aviation seat 1.

[0034] As a preferred embodiment, the total mass of the reference unit 300 is about 6 kg, and the robot load is 10 kg, which meets the robot load requirement.

[0035] As a preferred embodiment, the length of the reference plate 310 is 1300 mm.

[0036] As a preferred embodiment, the support beam 330 is a 4080 standard profile, which is light in weight and has good strength.

[0037] In order to better understand the present invention, the following Figure 1 - Figure 6 The working principle of the technical solution of the present invention is described in detail: When in use, each of the support bodies 100 is placed on the conveyor line in sequence and at intervals, and then each of the multi-seat aviation seats 1 is placed on each of the support plates 110 in sequence. When the multi-seat aviation seat 1 is placed on the support plate 110, the upper ends of each of the positioning pins 120 are respectively used to insert into the respective mounting holes of the bottom plate of the multi-seat aviation seat 1, thereby realizing the detachable and portable connection between the multi-seat aviation seat 1 and the support plate 110. The loading and unloading of the multi-seat aviation seat 1 are very quick. When the support body 100 carrying the multi-seat aviation seat 1 is transported to the preset workstation by the conveyor line, the first telescopic drive member 225 is started, and the telescopic end of the first telescopic drive member 225 is extended to drive the top plate 22 2 moves upward, so that the top of the turntable 223 and each of the carriers 224 abuts against the bottom of the support plate 110, and pushes the support plate 110 to move upward to a preset position. At this time, the support plate 110 is separated from the conveyor line. Then, the second telescopic driving member 232 is started, and the telescopic end of the second telescopic driving member 232 is extended to drive the mounting frame 231 to move upward until the clamping assembly 240 reaches the support plate 110. When the clamping assembly 240 reaches the support plate 110, the telescopic end of the third telescopic driving member 2423 retracts. Under the elastic force of the two elastic members 2422, the two driving rods 2421 can approach each other, thereby driving the two clamping blocks 241 are close to each other, so that the two V-shaped clamping grooves 2411 on the two clamping blocks 241 are engaged with the corresponding two V-shaped protrusions 131 on the support plate 110, thereby clamping the support plate 110, so that the support plate 110 can be fixed, and the stability during the adjustment process is improved. Then the operator adjusts the inclination angle of each dining table board of the multi-seat aviation seat 1 in turn until the top surface of each dining table board is in contact with the reference plate 310. When the operator adjusts the dining table board to contact the reference plate 310 upward, if over-adjustment occurs, the torque sensor 340 is stressed and sends an alarm signal to remind the operator. When the dining table board is adjusted downward to break away from the reference plate 310, the alarm prompt disappears. When the multi-seat aviation seat 1 is adjusted, the operator adjusts the dining table board to contact the reference plate 310 upward. After the inclination adjustment of each dining table board is completed, the telescopic end of the third telescopic driving member 2423 is extended, and under the elastic force of the two elastic members 2422, the two driving rods 2421 can move away from each other, thereby driving the two clamping blocks 241 to move away from each other, so that the two V-shaped clamping grooves 2411 on the two clamping blocks 241 are separated from the corresponding two V-shaped protrusions 131 on the supporting plate 110, thereby releasing the supporting plate 110, and the second telescopic driving member 232 is started, and the telescopic end of the second telescopic driving member 232 is retracted, which can drive the mounting frame 231 to move downward until the clamping assembly 240 reaches the bottom of the conveyor line, and then the first telescopic driving member 225 is started,The retracting end of the first telescopic driving member 225 can drive the top plate 222 to move downward, and the pallet 110 to move downward, so that the pallet 110 is repositioned on the conveyor line. The pallet 110 and the multi-seat aviation seat 1 are then moved to the next processing step on the conveyor line.

[0038] The online adjustment production line for multi-seat aviation seat dining tables provided by the present invention has the following beneficial effects: (1) The end of the docking block 130 has a V-shaped protrusion 131, and the ends of the two clamping blocks 241 have a V-shaped clamping groove 2411, and the V-shaped clamping groove 2411 is used to clamp or separate with the V-shaped protrusion 131, thereby improving the clamping effect of the support plate 110; (2) When the operator adjusts the dining table board upward to contact the reference plate 310, if over-adjustment occurs, the torque sensor 340 is stressed and sends an alarm signal to remind the operator. When the dining table board is adjusted downward to separate from the reference plate 310, the alarm prompt disappears. Based on the robot coordinate path motion technology of the user's seat configuration changes and process requirements, the dining table board contact feedback prompt system during the adjustment process is adapted to the workstation precision positioning system of the assembly line; (3) This multi-seat aviation seat dining table online adjustment production line can provide a benchmark for online assembly and adjustment of the preset angles and consistency requirements of multiple dining tables of multi-seat seats, thereby realizing portable dining table inclination adjustment and improving the efficiency of dining table inclination adjustment.

[0039] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
