Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, and in particular to an adhesive coating device for automotive exterior panels. Background Technology

[0002] In today's era, technology is developing at an unprecedented pace, and consumer demands are becoming increasingly diverse. Automotive exterior components, as external decorative products, play a crucial role in the overall design of a vehicle. They not only provide essential protection but also significantly enhance the vehicle's aesthetics, satisfying consumers' pursuit of personalized and high-quality vehicle appearance.

[0003] In the manufacturing process of automotive exterior parts, a crucial step is bonding the accessories to the exterior parts using adhesives. The quality of this process directly affects the performance and lifespan of the exterior parts. To achieve efficient and precise adhesive application, various adhesive application equipment has emerged on the market.

[0004] Among them, patent CN118950380A discloses a glue-applying device for the production of lightweight exterior parts. This device mainly consists of a worktable, a moving mechanism, a glue-feeding mechanism, and a glue-scraping mechanism. Several positioning blocks are set on the worktable for accurately placing exterior parts; the moving mechanism is mounted on a fixed frame and can move the glue-applying head; the glue-feeding mechanism is also located on the fixed frame and includes a glue-holding tank, a first cylinder, a second cylinder, and a sliding plate. The glue-holding tank is placed on the support of the fixed frame, and the first cylinder is mounted on the top of the support. The lower end of its piston rod has a push plate that slides through the inner wall of the glue-holding tank. The glue-applying head is connected to the glue outlet at the bottom of the glue-holding tank via a glue-feeding hose, and the glue is dispensed from the outlet by the push of the first cylinder; the glue-scraping mechanism is located at the lower end of the moving frame and sleeved on the glue-applying head, used to smooth the applied glue.

[0005] However, the aforementioned glue application equipment has some obvious drawbacks. First, the glue tank is mounted on a bracket on a fixed frame, which increases the pressure load on the worktable. Prolonged high load can affect the stability and lifespan of the worktable, thus impacting the overall performance of the glue application equipment. Second, glue replenishment becomes very inconvenient. When the glue in the tank runs out, it needs to be replenished, but due to the installation location limitations, the operation is cumbersome, wasting time and labor costs. Furthermore, the equipment only controls glue dispensing through the push of the first cylinder, which has low precision. In actual glue application, different exterior parts may require different glue amounts and speeds, and simple cylinder operation cannot meet these diverse needs, easily leading to uneven glue application, glue waste, and other problems, thus affecting the processing quality of the exterior parts. Therefore, developing a more efficient, precise, and easy-to-operate glue application equipment is of significant practical importance. Utility Model Content

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] like Figures 1 to 4 As shown, this utility model claims protection for an adhesive application device for automotive exterior panels, comprising a frame 1, a worktable 2, a three-axis robotic arm system 3, an adhesive application gun head 4, a placement table 5, and an adhesive supply system. The frame 1 serves as the main support structure, providing stable support for the entire adhesive application device. The worktable 2 is mounted on the frame 1 to support the automotive exterior panels to be adhesive-applied. An electrical cabinet 101 is located on the frame 1 below the worktable 2, providing centralized installation of electrical control components for convenient electrical control of the entire device. The electrical cabinet 101 has an openable door on its front, allowing for maintenance of the electrical control components.

[0031] In this embodiment, a three-axis robotic arm system 3, fixedly mounted on the frame 1, has an adhesive applicator head 4 connected to its actuator. The three-axis robotic arm system 3 can drive the adhesive applicator head 4 to move along a preset adhesive application trajectory. In actual operation, the operator can preset the adhesive application trajectory in the control system according to the specific adhesive application requirements of the automotive exterior panel. After receiving the instruction, the three-axis robotic arm system 3 accurately drives the adhesive applicator head 4 to move, thereby realizing automated adhesive application to the surface of the automotive exterior panel. The control system is a PLC system, which is electrically connected to the three-axis robotic arm system 3 and used to control the movement of the three-axis robotic arm. This control technology is a mature existing technology and will not be described in detail here.

[0032] A placement platform 5 is provided on the worktable 2, which is used to fix the automotive exterior panels placed on the worktable 2. At least one guide rail 14 is provided on the worktable 2, and the placement platform 5 is slidably mounted on the guide rail 14. A drive device is also provided, which is connected to the placement platform 5. Driven by the drive device, the placement platform 5 can move along the guide rail 14, thereby adjusting its positioning on the automotive exterior panels to accommodate panels of different sizes and shapes. The drive device can be a cylinder or a lead screw module, which is not limited here.

[0033] The adhesive supply system is used to supply adhesive to the glue gun head 4. Specifically, it includes an adhesive container 6 located beside the frame 1, used to hold the adhesive. The container 6 has a jacketed heating layer 601 on its wall, within which electric heating wires 602 are evenly wound. When energized, the electric heating wires 602 generate heat, which heats and maintains the adhesive in the container 6, ensuring good flowability at a suitable temperature. An agitator is installed inside the container 6. The drive motor 10 of the agitator is mounted on the container lid, and the agitator shaft 11 extends into the container and is connected to agitator blades 12. The drive motor 10 rotates the agitator shaft 11 and agitator blades 12, preventing sedimentation or stratification of the adhesive during settling.

[0034] In addition, a liquid level sensor 13 is installed on the glue container 6, which can monitor the remaining amount of adhesive in the container in real time. When the remaining amount of adhesive reaches the preset low level, the liquid level sensor 13 will issue a prompt or alarm signal to remind the operator to replenish the adhesive in time.

[0035] To ensure that the adhesive can be fully pumped and utilized and to reduce residue, in this embodiment, the bottom of the adhesive container 6 is designed in a conical shape, and the adhesive outlet is opened at the bottom of the adhesive container 6. The adhesive outlet is connected to the gear pump 803 through a pipe, which helps to completely discharge the adhesive.

[0036] The adhesive container 6 is connected to a plunger pump 7, which extracts the adhesive from the container 6 and delivers it to the delivery pipe, thus pressurizing the adhesive. The delivery pipe uses high-pressure Teflon tubing, which has excellent pressure resistance and corrosion resistance, ensuring stable delivery of the adhesive. The delivery pipe is connected to a metering system 8, which includes a servo motor 801, a reducer 802, and a gear pump 803 connected in sequence. The servo motor 801 provides power, which, after being reduced in speed by the reducer 802, drives the gear pump 803. The outlet end of the delivery pipe is connected to the inlet of the gear pump 803, which further delivers the adhesive to the outlet pipe. The gear pump 803 prioritizes high metering accuracy, facilitating precise and stable adhesive output.

[0037] The outlet of gear pump 803 is connected to the glue gun head 4 via a glue dispensing line. A pressure sensor 9 is installed at the outlet of gear pump 803 to monitor the glue dispensing pressure in real time, ensuring stable adhesive pressure during the glue application process. A glue valve is also installed on the glue dispensing line between gear pump 803 and glue gun head 4. The glue valve is used to precisely control the flow of adhesive, accurately controlling the supply of adhesive according to the application requirements, thus controlling the glue dispensing.

[0038] The working principle of this utility model is as follows: The operator places the car exterior panel to be glued on the placement platform 5 of the workbench 2 and fixes it. The drive device is started, causing the placement platform 5 to move along the guide rail 14 to a suitable position. Then, the three-axis robotic arm system 3 and the glue supply system are started. The plunger pump 7 in the glue supply system delivers the adhesive in the glue tank 6 to the metering system 8, and then further delivers it to the glue application gun head 4 via the gear pump 803. The glue dispensing pressure is monitored in real time by the pressure sensor 9, and the glue valve precisely controls the flow of adhesive. The three-axis robotic arm system 3 drives the glue application gun head 4 to move along a preset trajectory to perform automated glue application on the surface of the car exterior panel.

[0039] During the adhesive application process, the liquid level sensor 13 monitors the remaining amount of adhesive in the glue container 6 in real time, and issues a prompt or alarm signal when the remaining amount is insufficient. During the operation, the temperature and uniformity of the adhesive are ensured by turning on the jacketed heating layer 601 and the stirring device of the glue container 6.

[0040] Compared with existing technologies, by placing the glue container 6 on the side of the frame 1, the pressure on the worktable 2 is not increased, ensuring its stability and lifespan; the glue supply system has a metering system 8, a pressure sensor 9 and a glue valve, which accurately controls the glue dispensing pressure and on / off, meets diverse glue application needs, avoids uneven glue application and glue waste, and improves the processing quality of exterior parts.

[0041] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
