[0031] It is worth adding that:

[0032] The door liner thermoforming machine 1 is specifically a three-station door liner thermoforming machine.

[0033] The conveying device 2 is specifically a material supporting and positioning carrier trolley, which is used for the initial centering and positioning of the door inner liner, picking up the formed door inner liner, and accurately feeding it under the subsequent conveying first manipulator 3. The conveying device 2 is composed of a chassis, a door liner long side positioning component, a door liner wide side positioning component, a servo motor, a linear guide rail, a ball screw, a guide rod cylinder, a pneumatic control system, an electric control system, etc. When the edge trimming machine fails, the carrier trolley sends the door liner outside the line for temporary manual blanking.

[0034] The first manipulator 3 is a loading manipulator, which is used to convey the formed door inner liner to a specified position. It adopts an independent drive structure to meet the left and right horizontal feeding functions, and is composed of a suction cup assembly, a guide rail and a drive assembly, etc. The manipulator is lifted by a cylinder, translated by a servo motor, and the vacuum suction cup is controlled by a pneumatic vacuum generator. The guide rail and the drive assembly are composed of a cross beam, a linear guide rail, a gear rack, a servo motor, etc.

[0035] The edge trimming and hole punching device 4 is a standardized positioning tooling platform, which mainly completes the processes of edge trimming of the door inner liner and punching air holes in the door inner liner. It is mainly composed of a base, a gantry mounting frame, an automatic edge trimming machine, a changeover table, a door inner liner positioning tooling, the lower part of the air hole punching tooling, a CNC numerical control cutting tool, a positioning material supporting mechanism, an automatic edge pressing mechanism, a cylinder, a linear guide rail, a gear rack, a servo motor and other parts. The edge trimming of the door inner liner is completed on the platform. The edge trimming machine cuts open the waste around the door inner liner, replacing manual edge trimming. The air holes are punched in the door inner liner on the platform. When the blanking manipulator descends to pick up the door liner, the upper and lower parts of the air hole punching tooling are closed to realize automatic air hole punching.

[0036] The second manipulator 5 is a blanking manipulator, which realizes the automatic separation of the door inner liner and the surrounding waste by controlling the manipulator suction cup, conveys the door inner liner that has completed edge trimming and hole punching above the blanking belt line, and conveys the surrounding waste above the waste conveying line. It is composed of a top frame, a suction cup assembly, the upper part of the air hole punching tooling, an automatic material separating device, a linear guide rail, a gear rack, a lifting cylinder and a driving motor, etc.

[0037] The blanking belt line 6 picks up the door inner liner that has completed edge trimming and air hole punching and conveys it to the manual material taking position. It is composed of a bracket, a driving shaft, a driven shaft, a support plate, a tensioning shaft, a roller, a tensioning mechanism, a motor and a flat belt.

[0038] The inner liner that has completed edge trimming and vent hole punching is conveyed out of the edge trimming machine. The door liner and waste materials are separated and stacked on the blanking belt line through the automatic material distribution device on the robot arm.

[0039] The waste material transmission device 7 picks up the waste materials around the door inner liner after edge trimming and conveys them into the waste material box. It consists of a bracket, a driving shaft, a driven shaft, a support plate, a motor, and a belt.

[0040] The track frame 8 is a double-track truss. The loading robot arm and the unloading robot arm are installed on the double-track truss, and it consists of a double truss, linear guide rails, brackets, helical gears and racks, servo motors, an automatic lubrication system, etc.

[0041] For the electrical system and pneumatic system, the centralized air distribution method is adopted, and it consists of accessories such as a triple unit, solenoid valves, vacuum components, and pipelines. The electric control system adopts Mitsubishi PLC control and a CNC numerical control operating system to achieve separate manual and automatic control, and can be connected for automatic flow production.

[0042] The punching device 9 is used to drill holes in the door inner liner.

[0043] After the door inner liner is formed by a three-station door liner thermoforming machine, the servo clamp of the thermoforming machine moves according to parameters to clamp the door inner liner, and the door inner liner is conveyed out by the conveyor chain. After the door inner liner reaches above the carrier cart, the clamp is released, and the door inner liner falls onto the carrier cart. The carrier cart holds the door inner liner and completes centering and positioning according to the product size. The cart moves to accurately send the door inner liner to the working position of the loading robot arm and waits for the robot arm to pick it up. The loading robot arm extracts the door inner liner and conveys it above the edge trimming and hole punching platform. The suction cup of the loading robot arm is released, and the door inner liner falls onto the positioning fixture. Secondly, the positioning fixture and the edge pressing mechanism work to complete the positioning and fitting of the door inner liner. Secondly, the CNC numerical control cutting tool starts to work to complete the trimming of the waste materials around the perimeter. Secondly, the unloading robot arm moves above the edge trimming and hole punching platform and descends to work, synchronously realizing punching vent holes and picking up the door inner liner. Secondly, the unloading robot arm conveys the door inner liner and the waste materials around the perimeter to fall onto the blanking belt line and the waste material transmission line respectively. Finally, the qualified door inner liners are taken by workers.
