Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts assembly, in particular to a foam feeding device of an automobile exterior decoration part foam automatic attaching device. 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] First, it is difficult to ensure the accuracy of the pasting position when pasting manually. Due to the complex shape of the car B-pillar and the differences in the size and structure of the B-pillar of different models, it is difficult to accurately attach the foam to the predetermined position when pasting it manually, which will not only affect the heat insulation and sound insulation effect of the foam, but also may cause a gap between the foam and the B-pillar, 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 B-pillar. 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 becoming a bottleneck in the automobile production process.

[0005] In summary, there is an urgent need for an automated foam pasting device that can improve pasting position accuracy and work efficiency to meet the strict requirements of modern automobile manufacturing industry on production efficiency and product quality. Summary of the invention

[0008] The utility model with the above characteristics: the foam feeding device drives the clamping roller assembly and the waste collection roller to rotate through the power component, thereby realizing automatic material transportation and automatic waste recovery, and improving the efficiency of foam feeding; by arranging a pressing component on the discharge table, the material to be peeled is positioned, effectively avoiding material deviation, and cooperating with the next process of the whole machine to improve the working efficiency and working accuracy of the equipment; the clamping roller assembly arranged in the discharge frame can assist the pressing component to flatten the material, and at the same time assist the waste collection roller to recover the waste.

[0009] The utility model is further configured as follows: the pressing assembly comprises a lifting cylinder and a pressing piece arranged on both sides of the discharge rack, the two ends of the pressing piece are connected to the output ends of the lifting cylinder, the end face of the pressing piece is arranged parallel to the discharge platform, and a rectangular frame is opened thereon.

[0010] The utility model with the above-mentioned characteristics: the pressing piece is connected to the output end of the lifting cylinder through both ends, so that the pressing piece can intermittently press the material. When pressing the material, the lifting cylinder drives the pressing piece to descend until the pressing piece and the material are against each other. The rectangular frame opened on the pressing piece just frames the foam to be peeled off, avoiding affecting other foams to be peeled off. After the foam is peeled off, the lifting cylinder lifts the pressing piece again, and the material moves forward driven by the power component.

[0017] A further configuration of the utility model is that the clamping roller assembly includes a pressure roller and a rotating roller linked to a power assembly, the discharging frame includes two vertically arranged vertical plates, the vertical plates are provided with mounting grooves, the mounting grooves are provided with mounting blocks slidably connected to the mounting grooves, both ends of the pressure roller are plugged into the mounting blocks, one end of the pressure roller extends to the outside of the mounting block and is connected to a handle, the upper end of the mounting groove is open, a sealing strip is provided on it, and a spring is provided between the mounting block and the sealing strip.

[0018] The utility model with the above characteristics: the material includes foam and a base glue that supports the foam. After the foam is peeled off, the base glue passes through between the pressure roller and the rotating roller and is wound around the waste collection roller. The pressure roller is always pressed down under the action of the spring, so that the base glue can move with the rotating roller and thus be transported toward the waste collection roller. A handle is provided at one end of the pressure roller to lift the pressure roller when threading the material, thereby increasing the distance between the pressure roller and the rotating roller to facilitate threading.

[0019] A further configuration of the utility model is that a fixing plate is embedded in the lower part of the installation groove, and the fixing plate abuts against the lower part of the installation block.

[0020] The utility model with the above characteristics: by arranging the fixing plate to press against the mounting block, the mounting block is prevented from falling off from the mounting groove, thereby improving the installation stability of the pressing roller and ensuring the normal operation of the pressing roller.

[0021] A further configuration of the utility model is that guide strips are arranged on the inner walls on both sides of the installation groove, and guide grooves plugged with the guide strips are arranged on the inner walls on both sides of the installation block.

[0022] The utility model with the above characteristics: the guide strip in the installation groove has a guiding effect on the installation block, and when the pressure roller is lifted by the handle, it is ensured that the pressure roller can be lifted steadily and smoothly.
