[0002] With the development of automobile technology, people have put forward more new requirements for automobile functions, one of which is the removable hardtop. In order to achieve the product sound insulation requirements, the removable hardtop must be equipped with sound insulation felt. The installation of the removable hardtop felt is a key link, which directly affects the sealing, sound insulation effect and interior comfort of the car. The existing installation method of the removable hardtop felt mainly relies on manual laying and rolling, which has many problems and limitations.

[0003] First of all, the manual laying process is not precise and efficient, and it is difficult to ensure that the felt fits the hardtop surface perfectly, which can easily lead to hollowing, wrinkles and other problems between the felt and the hardtop. This not only affects the flatness of the felt, but may also cause noise and poor sealing during driving. At the same time, the process of manually laying and rolling the felt is cumbersome and time-consuming, requiring a lot of time and human resources, and has low production efficiency, making it difficult to meet the needs of modern automobile manufacturing for efficient and high-quality production. In addition, the felt primer has a certain degree of toxicity, and the primer liquid has a certain odor and chemical hazard. The working environment of manually laying the felt is harsh and can easily cause harm to the human body.

[0004] Therefore, an automated and precise operation method and equipment system is needed to realize the automated operation of hardtop felt primer and avoid contact between personnel and the primer environment. Summary of the invention

[0052] First Embodiment

[0053] like Figure 1 to Figure 6 As shown, the present embodiment provides a detachable hardtop felt primer system for automobiles, including a primer liquid supply system 100, a spraying robot 200, a rotating workbench 300 and a control module. The above components work in coordination with each other to replace manual felt primer coating and realize automated operation of hardtop felt primer coating.

[0054] Among them, Figure 6 As shown, the primer liquid supply system 100 includes a primer liquid metering pump 101 and a primer liquid supply tank 102. The primer liquid metering pump 101 is connected to the spraying robot 200 through a pipeline, and the primer liquid metering pump 101 pumps a certain amount of primer liquid from the primer liquid supply tank 102 into the spraying robot 200.

[0055] like Figure 1 to Figure 3 As shown, under the control of the control module, the spray robot 200 can apply the primer liquid on the detachable hardtop workpiece according to the planned path, which includes a robot mounting support 201, a robot moving arm 202, a robot coating tool and a primer liquid supply pipeline 203. Among them, the robot moving arm 202 is fixed on the robot mounting support 201, and the primer liquid supply pipeline 203 is fixed on the robot moving arm 202. A coating tool is arranged at the end of the robot moving arm 202, which can drive the coating tool to move in all directions. The coating tool includes a coating nozzle 204, a robot connecting flange 205, and a robot and operation buffer telescopic joint 206. A liquid supply pipeline interface 207 is arranged on the side of the coating nozzle 204. Among them, the robot connecting flange 205 connects the robot moving arm 202 and the robot and operation buffer telescopic joint 206. A coating nozzle 204 is connected below the robot and the working buffer telescopic joint 206, and a liquid supply pipeline interface 207 is provided on the coating nozzle 204. The liquid supply pipeline interface 207 is connected to the primer liquid supply pipeline 203, so that the quantitative primer liquid pumped out from the primer liquid supply system 100 is sprayed from the coating nozzle 204 to the primer workpiece located on the rotating workbench 300.

[0056] like Figure 4 , Figure 5 As shown, the rotating workbench 300 is used to fix and transfer the primer tooling, including a workbench table and a rotary drive system. The workbench table is divided into two parts: a loading position 301 and a robot coating position 302. The loading position 301 is used to fix the workpiece to be coated, and the robot coating position 302 is arranged below the spray robot 200 for coating the primer liquid on the workpiece to be coated. In addition, a locking cylinder 301 and a clamping cylinder 302 are arranged below the rotating workbench 300 table to realize the positioning and fixing of the workpiece on the workbench. In addition, a rotating cylinder 303 is also arranged on the rotating workbench 300 to rotate the workbench table 180 degrees. When the workpiece on the coating position is coated, the rotating table rotates 180 degrees under the drive of the rotating cylinder 303, and the coated workpiece is rotated to the loading position 301 for unloading. At the same time, the uncoated workpiece on the original loading position 301 reaches the robot coating position 302 for primer coating.

[0060] Step S2: The rotating worktable 300 rotates 180 degrees, and the workpiece to be coated reaches the robot's operating position and is positioned and locked.

[0061] Step S3: The end coating tool of the spraying robot 200 coats the primer on the workpiece according to the planned path. Meanwhile, the next workpiece to be coated is placed on the loading position 301.

[0062] Step S4: After the coating is completed, the rotating table rotates 180 degrees to rotate the coated workpiece to the loading position 301. At the same time, the new workpiece to be coated reaches the robot coating position 302.
