Description

Technical Field

[0001] The utility model relates to the field of automatic foam attachment of automobile parts, in particular to a foam fixture for automatic foam attachment equipment of automobile exterior decoration parts. Background Art

[0002] Automotive exterior parts include A-pillars, B-pillars, C-pillars, D-pillars and other parts installed on the outside of the car. For example, during the automobile manufacturing process, the B-pillar needs to be pasted with foam at multiple locations to achieve functions such as heat insulation, sound insulation, and shock absorption, thereby improving the comfort and safety of the car. However, the existing pasting method is mainly manual, which has many disadvantages.

[0003] Firstly, it is difficult to ensure the accuracy of the pasting position when manually pasting. Due to the complex shapes of automobile exterior trims and the differences in size and structure of exterior trims of different models, it is difficult to accurately attach the foam to the predetermined position when manually pasting it. This will not only affect the heat insulation and sound insulation effects of the foam, but may also cause gaps between the foam and the exterior trim, reducing the overall sealing and aesthetics of the car.

[0004] Secondly, manual pasting is inefficient. On large-scale automobile production lines, manual pasting of foam requires a lot of manpower and time. Operators need to cut, position and paste the foam one by one to various positions of the exterior parts. This process is cumbersome and time-consuming. In a high-intensity working environment, manual operation is also prone to fatigue, which further reduces work efficiency, seriously affecting the overall work efficiency of foam pasting, and has become a bottleneck in the automobile production process.

[0005] In summary, the existing manual foam pasting method has many problems in the production and manufacturing of automotive exterior parts. There is an urgent need for an automated foam pasting device that can improve the accuracy of pasting position and work efficiency to meet the strict requirements of modern automobile manufacturing industry on production efficiency and product quality. Summary of the invention

[0006] The technical problem to be solved by the utility model is to provide a foam tooling fixture for an automatic foam attaching device for automobile exterior trim parts in view of the deficiencies of the above-mentioned prior art.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foam tooling fixture for an automatic foam attachment device for automobile exterior parts, comprising: a mechanical arm connection seat, used to connect with a mechanical arm; multiple groups of foam suction cups, arranged on the mechanical arm connection seat for absorbing and transferring foam; multiple groups of foam grippers, arranged on the mechanical arm connection seat for clamping and transferring foam;

[0008] The foam pressing plate is arranged on the robot arm connecting seat and is used to press the foam after it is attached to the exterior decoration.

[0009] Using the above technical solution, the robot arm connecting seat is the core support and connection component of the entire foam tooling fixture. The robot arm connecting seat is designed to be compatible and connected with the industrial robot arm, and ensure that the entire device can be accurately positioned and moved by the robot arm, thereby realizing diversified work steps. The foam suction cup is installed on the robot arm connecting seat to adsorb the foam material. These suction cups generate suction through negative pressure, thereby firmly grasping the foam to achieve foam picking and transportation. It is suitable for some foams that are long or too wide to be difficult to clamp. The foam clamp is also installed on the robot arm connecting seat to clamp and transport foam. The design of the clamp enables it to stably clamp small-sized foam to ensure the stability of the foam during transportation. The foam pressure plate is also a component installed on the robot arm connecting seat, which is used to clamp the foam after it is attached to the automotive exterior. Pressing, the design of the pressure plate ensures close contact between the foam and the exterior trim to improve the bonding effect and completion, and improve the quality of the cotton pasting. This tooling reduces manual intervention through automated operation, significantly improves the speed of foam pasting and the efficiency of the entire production process. The automated equipment can perform tasks with higher repeatability accuracy, ensuring that the foam is accurately attached to the predetermined position of the exterior trim. Precise control and pressing ensure close contact between the foam and the exterior trim, improve heat insulation, sound insulation and shock absorption, thereby improving the quality and performance of the final product. The automated cotton pasting equipment undertakes repetitive and physically demanding work, reduces the labor intensity of operators, and reduces errors caused by fatigue. The entire tooling fixture realizes automation and precise control of the foam pasting process, thereby improving production efficiency, product quality and operational safety.

[0010] The above-mentioned foam tooling fixture for the automatic foam attachment equipment of automobile exterior parts can be further configured as follows: the mechanical arm connecting seat is respectively provided with a suction cup mounting plate for arranging the foam suction cups side by side and a clamping jaw mounting plate for arranging the foam clamping jaws side by side, the suction cup mounting plate is provided with a suction cup lifting mechanism for controlling the lifting of the foam suction cup corresponding to each group of foam suction cups, the clamping jaw mounting plate is provided with a clamping jaw lifting mechanism for controlling the lifting of the foam clamping jaws corresponding to each group of foam clamping jaws, and the suction cup mounting plate or the clamping jaw mounting plate is provided with a pressure plate lifting mechanism for controlling the lifting of the foam pressure plate.

[0011] With the above technical solution, a special mounting plate is provided on the robot arm connection seat, which is used for the side-by-side installation of the foam suction cup and the foam clamp. This design allows multiple sets of suction cups and clamps to work at the same time, and cooperates with the transfer of longer foam strips, thereby improving the efficiency and flexibility of the operation. Both the suction cup mounting plate and the clamp mounting plate are designed with precise positioning holes and fixing devices to ensure the correct installation and stable operation of the suction cup and clamp. Each set of foam suction cups, foam clamps and foam pressing plates are respectively equipped with independent lifting mechanisms, usually using actuators such as slide cylinders or electric push rods. These lifting mechanisms can accurately control the vertical movement of the suction cups, clamps and pressing plates to achieve independent picking, placement and pressing of foam, and can work independently without interfering with other components, ensuring that the suction cups can reach the work smoothly and accurately. The position improves the accuracy and repeatability of the operation, and accurately controls the clamping force and position. Through the side-by-side arrangement of suction cups and clamps and their respective independent lifting mechanisms, synchronous or asynchronous operation of multiple sets of suction cups and clamps can be achieved, and the side-by-side structure enables adjacent components to work together, so that the equipment can adapt to foams and exterior trims of different sizes and shapes, improves the flexibility and adaptability of the production line, and significantly improves the efficiency of foam attachment. The independently controlled lifting mechanism can accurately control the position of the suction cups and clamps to ensure accurate picking, handling and placement of the foam, improving the accuracy of the operation. Precise suction cup and clamp control and precise clamping of the pressure plate ensure close contact between the foam and the exterior trim, improve the heat insulation, sound insulation and shock absorption effects of the product, thereby improving product quality.

[0012] The above-mentioned foam tooling fixture for the automatic foam attachment equipment of automobile exterior parts can be further configured as follows: the pressure plate lifting mechanism includes a pressure plate slide cylinder, the pressure plate slide cylinder is installed on the clamp mounting plate, and the output end is connected to the foam pressure plate, the end of the foam pressure plate away from the robot arm connecting seat is bent outward to form a clamping plate, and the pressure plate is driven to rise and fall axially by the pressure plate slide cylinder.

[0013] With the above technical solution, the pressure plate lifting mechanism is composed of a pressure plate slide cylinder, which is a linear actuator usually used to provide linear motion. In this design, the pressure plate slide cylinder is installed on the clamp mounting plate to ensure that the pressure plate lifting mechanism can be stably fixed and perform its function. The end of the foam pressure plate away from the robot arm connection seat is bent outward to form a clamping plate. This allows the pressure plate to apply pressure to the foam at a certain angle and area during the lifting process, thereby achieving more effective clamping. Through the extension and retraction of the pressure plate slide cylinder, the pressure plate is driven to be lifted axially so that the pressure plate can move in the vertical direction to adapt to foams and exterior trims of different thicknesses, ensuring the adaptability and effectiveness of the clamping process. The automated clamping process can be carried out quickly and continuously, significantly improving the efficiency and cotton pasting quality of the production line.

[0014] The above-mentioned foam tooling fixture for the automatic foam attachment equipment of automobile exterior parts can be further configured as follows: the clamp lifting mechanism includes a clamp slide cylinder, the foam clamp includes a finger cylinder, the clamp slide cylinder is installed on the clamp mounting plate, and the output end of the clamp slide cylinder is connected to the finger cylinder, and the finger cylinder is driven to rise and fall axially through the clamp slide cylinder.

[0015] Using the above technical solution, the gripper lifting mechanism adopts a gripper slide cylinder, which is responsible for controlling the vertical movement of the foam gripper, so that the gripper can be accurately moved to the desired position to pick up or release the foam. The foam gripper is composed of a finger cylinder, which is used to accurately clamp and release small-sized foam. The design of the finger cylinder enables it to open and close flexibly. The telescopic movement of the gripper slide cylinder can directly drive the finger cylinder to perform axial lifting and lowering, thereby realizing the opening and closing of the gripper. The automated clamping process can be carried out quickly and continuously, significantly improving the efficiency of the production line.

[0016] The above-mentioned foam tooling fixture for the automatic foam attachment equipment of automobile exterior decoration parts can be further configured as follows: the output ends of the finger cylinders are respectively installed with corresponding external clamping plates, one end of the external clamping plate is connected to the output end of the finger cylinder, and the other end is bent toward each other to form an L-shaped clamping enlargement part, and there is a clamping space for clamping foam between the clamping enlargement parts, the clamping spaces of adjacent finger cylinders are on the same horizontal plane, and the finger cylinders drive the clamping enlargement parts to move closer to or separate from each other.

[0017] By adopting the above technical scheme, an external clamping plate is installed at the output end of the finger cylinder so that it can be synchronized with the movement of the finger cylinder to ensure precise clamping action. One end of the external clamping plate is connected to the output end of the finger cylinder, and the other end is bent toward each other to form an L-shaped clamping enlarged portion, which increases the clamping area and improves the stability and reliability of clamping. The clamping spaces of adjacent finger cylinders are on the same horizontal plane, which ensures that adjacent clamping claws can synchronously and cooperatively clamp foams of different specifications, while ensuring that the foam is evenly stressed during the clamping process, thereby avoiding deformation or damage of the foam due to uneven stress.

[0018] The above-mentioned foam tooling fixture for the automatic foam attachment equipment of automobile exterior parts can be further configured as follows: the suction cup lifting mechanism includes a suction cup slide cylinder, the foam suction cup is a needle suction cup, the suction cup slide cylinder is installed on the suction cup mounting plate, and the output end of the suction cup slide cylinder is connected to the needle suction cup, and the needle suction cup is driven to rise and fall axially through the clamp slide cylinder.

[0019] Using the above technical solution, the suction cup lifting mechanism is composed of a suction cup slide cylinder, which is responsible for controlling the vertical movement of the needle suction cup. The needle suction cup is accurately moved to the required position to pick up or release the foam. The needle suction cup is selected because it can provide multiple tiny adsorption points, thereby providing a larger contact area and stronger adsorption force when adsorbing the foam, thereby achieving stable clamping and transfer of the breathable foam. The automated adsorption and release process reduces the need for manual operation and improves production efficiency and automation.

[0020] The above-mentioned foam tooling fixture for the automatic foam attachment equipment for automobile exterior trims can be further configured as follows: the mechanical arm connecting seat is provided with an optical lens, and the optical lens is used to capture images of the exterior trims and foam.

[0021] By adopting the above technical solution, an optical lens is integrated on the robot arm connecting seat, which is responsible for capturing real-time images of automobile exterior trim and foam, and comparing them with pre-set images, so as to accurately determine whether the foam is incorrectly placed or omitted, and also determine whether the exterior trim has the same problem, and accurately perform steps such as foam re-inspection. Specifically, the image captured by the optical lens will be used to guide the robot arm to accurately attach the foam to the specific position of the exterior trim, and perform real-time analysis of the image to determine the exact position of the foam and the exterior trim. The vision guidance system makes the entire attachment process more automated, reduces human intervention, and improves the automation level of the production line. The vision guidance system can adapt to exterior trims of different models and sizes, improves the flexibility and adaptability of the production line, and automated visual guidance reduces the possibility of human error and improves the consistency and reliability of operations.

[0022] The above-mentioned foam tooling fixture for the automatic foam attachment equipment of automobile exterior parts can be further configured as follows: a light source is provided at one end of the robotic arm connecting seat close to the optical lens, and the light source is used to provide lighting for the optical lens. The foam tooling fixture also includes a control system, which is used to integrate the control of the foam pressing plate, foam clamp, foam suction cup, optical lens and light source to achieve automated operation.

[0023] By adopting the above technical solution, light sources are set at one end of the robot arm connecting seat close to the optical lens. These light sources provide necessary lighting for the optical lens to capture images, ensure image clarity and accuracy, highlight the characteristics of exterior parts and foam, reduce shadows and reflections, and thus improve the accuracy and reliability of image recognition. The control system is the brain of the entire fixture, responsible for receiving operation instructions and controlling all active parts on the robot arm connecting seat (including foam suction cups, foam clamps and foam pressure plates). The control system includes PLC (programmable logic controller), human-machine interface (HMI) and related software to achieve automated operation and precise control. The control system integrates the control of foam pressure plates, foam clamps, foam suction cups, optical lenses and light sources, so that all components are coordinated with each other to achieve automated operation. Through the control system, the entire process from image capture, foam picking, handling to attachment and pressing can be automated. The control system automatically adjusts the movements of foam pressure plates, foam clamps and foam suction cups according to the image data captured by the optical lens, thereby improving the consistency and reliability of the operation.

[0024] The above-mentioned foam tooling fixture for the automatic foam attachment equipment of automobile exterior parts can be further configured as follows: the number of the light sources is at least 2, and a light source mounting frame is provided at the position of the robotic arm connecting seat corresponding to the light source, and the light sources are respectively mounted on both sides of the light source mounting frame, and a clearance groove is formed in the middle for the optical lens to capture the picture.

[0025] By adopting the above technical solution, auxiliary lighting sources are set on both sides of the optical lens, allowing the optical lens to capture images without obstacles, while ensuring that the light source can evenly illuminate the entire working area, reducing shadows and reflections, and improving the clarity and accuracy of image capture.

[0026] The above-mentioned foam tooling fixture for the automatic foam attachment equipment of automobile exterior parts can be further configured as follows: the suction cup lifting mechanism, the pressure plate lifting mechanism and the clamp lifting mechanism are all slide cylinders, and the mechanical arm connecting seat is provided with an electromagnetic valve group that integrates the slide cylinder air pipe and connects to the air source.

[0027] Using the above technical solution, the suction cup lifting mechanism, the pressure plate lifting mechanism and the clamp lifting mechanism all use a sliding cylinder, which is an actuator that converts the pressure of compressed air into linear motion. It has the advantages of stability, controllability and precision. The fact that they are all set as sliding cylinders facilitates the maintenance of the equipment. The air pipes of all sliding cylinders are integrated on the robot arm connecting seat, which means that the air supply lines of all cylinders are centrally managed, simplifying the complexity of the air source connection, facilitating maintenance and troubleshooting. The solenoid valve group is used to control the compressed air supply of the sliding cylinder while also controlling the operation of the finger cylinder and the needle suction cup. The solenoid valve can respond quickly to electrical signals to ensure that the cylinder can receive compressed air to perform lifting and clamping actions. The design of the air pipe integration and the solenoid valve group simplifies the maintenance and operation of the system, allowing maintenance personnel to more easily perform fault diagnosis and system maintenance.
