Description

Technical Field

[0001] The utility model relates to the field of automatic foam attachment of automobile parts, in particular to an automatic foam attachment device 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 trim, which is a cumbersome and time-consuming process. In a high-intensity working environment, manual operation is also prone to fatigue, further reducing work efficiency, seriously affecting the overall work efficiency of foam pasting, and becoming 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

[0008] With the above technical solution, the multi-axis manipulator has multiple degrees of freedom, can move and position flexibly, and realize complex spatial movement. It can accurately move the foam fixture to the predetermined position through precise control algorithms and drive systems to ensure that the foam can be accurately attached to the exterior parts. The manipulator connecting seat is used as a connecting part between the foam fixture and the multi-axis manipulator to ensure that the fixture can be firmly installed on the manipulator and move with the manipulator. The foam suction cup is used to absorb large specifications (long length or too wide width is not easy to clamp) ) of foam, and the negative pressure system generates adsorption force to firmly adsorb the foam on the suction cup. The foam clamp is used to clamp small-sized foam. The surface of the workpiece cotton-pasting platform is provided with a positioning groove to accommodate the exterior decoration, ensuring that the exterior decoration maintains a stable position without change during the cotton-pasting process. The workpiece positioning component is used to firmly adsorb the exterior decoration in the positioning groove to prevent it from detaching during the cotton-pasting process. The multi-axis manipulator drives the foam suction cup and foam clamp on the foam fixture to accurately attach the foam to the exterior decoration on the workpiece cotton-pasting platform. Through the precise control of the multi-axis manipulator and the adsorption and clamping functions of the foam fixture, the automatic attachment of the foam is realized, and the foam can be accurately attached to the exterior decoration of complex shapes and different positions. On large-scale automobile production lines, it can significantly reduce manpower and time consumption, improve overall production efficiency, and solve the problem of inaccurate manual pasting position.

[0010] Using the above technical solution, the foam pressing plate is also a component installed on the manipulator connecting seat, which is used to press the foam after it is attached to the automobile exterior trim. The design of the pressing plate ensures close contact between the foam and the exterior trim to improve the bonding effect and completion, and improve the quality of the foam. The pressing plate lifting mechanism usually adopts actuators such as sliding cylinders or electric push rods, which can accurately control the vertical movement of the pressing plate and realize independent compression control of the foam.

[0011] The above-mentioned foam automatic attaching device for the foam automatic attaching 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 manipulator 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.

[0012] With the above technical solution, the platen lifting mechanism is composed of a platen slide cylinder, which is a linear actuator usually used to provide linear motion. In this design, the platen slide cylinder is installed on the clamp mounting plate to ensure that the platen lifting mechanism can be stably fixed and perform its functions. The end of the foam platen away from the manipulator connection seat is bent outward to form a clamping plate. This allows the platen to apply pressure to the foam at a certain angle and area during the lifting process, thereby achieving more effective clamping. The platen slide cylinder is extended and retracted to drive the clamping plate to perform axial lifting so that the clamping 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 quality of the production line.

[0013] The above-mentioned foam automatic attaching device for the foam automatic attaching equipment of automobile exterior parts can be further configured as follows: the manipulator 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, and 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 clamps.

[0014] With the above technical solution, a special mounting plate is provided on the manipulator 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, which improves the efficiency and flexibility of the operation. 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 and foam clamps are equipped with independent lifting mechanisms, which usually adopt actuators such as slide cylinders or electric push rods. These lifting mechanisms can accurately control the suction The vertical movement of the disc and the clamping jaws enables independent picking up and placement of the foam, and both can work independently without interfering with other parts, ensuring that the suction cup can reach the working position smoothly and accurately, improving the accuracy and repeatability of the operation. Through the side-by-side arrangement of the suction cups and clamping jaws and their respective independent lifting mechanisms, synchronous or asynchronous operation of multiple groups of suction cups and clamping jaws 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, improving the flexibility and adaptability of the production line, and significantly improving the efficiency of foam attachment.

[0016] 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.

[0017] The above-mentioned foam automatic attaching device for the foam automatic attaching equipment of automobile exterior 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.

[0018] 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.

[0019] The above-mentioned foam automatic attaching device for 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.

[0020] 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.

[0021] The above-mentioned foam automatic attaching device for automobile exterior parts can be further configured as follows: a solenoid valve group connected to an external air source is provided on the manipulator connecting seat, and the solenoid valve group respectively controls the opening and closing actions of the suction cup slide cylinder, the clamp slide cylinder and the pressure plate slide cylinder, the finger cylinder and the needle suction cup.

[0022] Using the above technical solution, the suction cup lifting mechanism, the pressure plate lifting mechanism and the gripper lifting mechanism all use sliding cylinders, and the air pipes of all sliding cylinders are integrated on the manipulator connecting seat, which means that the air supply lines of all cylinders, finger cylinders and needle suction cups are centrally managed, simplifying the complexity of the air source connection and facilitating maintenance and troubleshooting. The solenoid valve group is used to control the compressed air supply of the sliding cylinder, finger cylinder and needle suction cup. The solenoid valve can respond quickly to electrical signals to ensure that all components 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.

[0023] The above-mentioned foam automatic attaching device for an automobile exterior foam automatic attaching device can be further configured as follows: the manipulator connecting seat is provided with an optical lens, the optical lens is used to capture the image of the exterior trim and the foam, the manipulator connecting seat is provided with light sources at both ends close to the optical lens, the manipulator connecting seat is provided with a light source mounting frame at the location corresponding to the light source, the light sources are respectively mounted on both sides of the light source mounting frame, and a make way groove is formed in the middle for the optical lens to capture the image.

[0024] By adopting the above technical solution, an optical lens and light sources on both sides are integrated on the manipulator connection seat. The lens is responsible for capturing real-time images of automotive exterior trim and foam, and comparing them with pre-set images, so as to accurately determine whether the foam is placed incorrectly 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 manipulator to accurately attach the foam to a 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 visual guidance system makes the entire attachment process more automated, reduces manual intervention, and improves the automation level of the production line. The visual guidance system can adapt to exterior trims of different models and sizes, improving the flexibility and adaptability of the production line. Automated visual guidance reduces the possibility of human error and improves the consistency and reliability of operations. The light source provides the necessary lighting for the optical lens to capture the image, ensuring image clarity and accuracy, highlighting the features of the exterior trim and foam, reducing shadows and reflections, and thus improving the accuracy and reliability of image recognition.

[0025] The above-mentioned foam automatic attaching device for automobile exterior parts foam automatic attaching equipment can be further configured as follows: the workpiece positioning assembly includes a plurality of workpiece suction cups arranged in the positioning groove, vacuum generators respectively connected to the workpiece suction cups, and a digital display pressure switch connected to the vacuum generator.

[0026] By adopting the above technical scheme, the workpiece suction cup uses the negative pressure generated by the vacuum generator to firmly adsorb the exterior decoration in the positioning groove, ensuring that the exterior decoration will not be displaced or fall off during the cotton pasting process, thereby improving the stability and reliability of the cotton pasting operation. Multiple workpiece suction cups can be evenly distributed at various contact points of the exterior decoration to provide uniform adsorption force, which is suitable for exterior decorations of different shapes and sizes, enhancing the versatility and adaptability of the device. The digital pressure switch monitors the pressure in the vacuum system in real time to ensure that the pressure is within the set range. If the pressure is abnormal, the digital pressure switch will send a signal in time to prompt the operator or control system to make adjustments. By monitoring the pressure in real time, the exterior decoration caused by vacuum system failure can be prevented from falling off, and cotton pasting failure or quality problems caused by insufficient adsorption force can be reduced, thereby improving the stability of the production process and product quality. The cooperation between the digital pressure switch and the vacuum generator realizes the automatic control of the vacuum system, reduces manual intervention, improves production efficiency, reduces foam scrapping caused by displacement or falling off of exterior decorations, improves material utilization, and reduces production costs.
