Description

Technical Field

[0001] This invention relates to the field of foam processing equipment technology, and more particularly to a foam winding device. Background Technology

[0002] Expanding foam is a polymer material with special physical properties: at high temperatures, its volume easily expands and its surface stickiness increases significantly; while at low temperatures, the material becomes harder and almost non-sticky. Currently, manufacturers typically produce expanding foam in the form of thin sheets for sale.

[0003] In the commercial aerospace field, to meet the structural requirements of specific components, thin sheets of expanded polystyrene (EPS) need to be tightly wrapped around the workpiece to form a cylindrical structure. This process demands high precision in the wrapping, uniformity, and adhesion between the EPS layers. Currently, this wrapping process relies entirely on manual operation under constant temperature conditions: operators manually wrap the EPS tape around the workpiece layer by layer, applying pressure to prevent it from detaching. As the batch sizes of workpieces in commercial aerospace increase and the requirements for wrapping accuracy and consistency become more stringent, manual operation reveals several significant problems: first, it is time-consuming, often requiring several minutes or even longer to wrap a single product, severely hindering production efficiency; second, labor costs are high, and prolonged repetitive labor easily leads to operator fatigue and inconsistent wrapping quality; and third, it fails to meet the rapid iteration and large-scale production demands of commercial aerospace. Therefore, there is an urgent need for equipment that can automatically complete the entire process of EPS feeding, clamping, wrapping, and unloading to replace manual labor and improve production efficiency and product quality consistency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a foam wrapping device to solve the problems of low efficiency, high cost and unstable quality of manual wrapping, and to realize the full automation of foam wrapping operation.

The guide plates ensure that the workpiece to be wound does not deviate too much from the center during the conveying process, and the oblong hole design allows the guide plates to be adjusted left and right to accommodate more specifications; the baffle blocks the workpiece to be wound from falling off, and a gap is left between the surface of the baffle and the belt to avoid interference.

[0014] Furthermore, a sensor mounting plate is fixedly provided on the upper side of the base plate at a position corresponding to the winding unit and the clamping rotation unit. A sensor is installed on the sensor mounting plate to sense the feeding position of the foam tape.

With detachable and replaceable clamping fingers and an adjustable guide plate with oblong holes, it can quickly adapt to different sizes and specifications of parts to be wrapped, offering strong versatility. The wrapping unit employs a round bar combined with a rotary table structure; during the wrapping process, the round bar applies controllable pressure to the foam tape, ensuring tight wrapping and preventing it from falling off.

The clamping and rotating unit 5 includes a second linear module 51 provided on the upper side of the base plate 1, a movable connecting plate 52 movably provided on the second linear module 51, a rotating table fixing plate 53 provided on the movable connecting plate 52, a second rotating table 54 provided on the rotating table fixing plate 53, a three-finger gripper 55 provided at the output end of the second rotating table 54, and a gripper 56 provided on the three-finger gripper 55.

[0035] An outer cover 6 is provided on the upper side of the base plate 1, enclosing the belt conveyor unit 2, the feeding unit 3, the winding unit 4, and the clamping and rotating unit 5. A feed inlet 61 for the workpiece to be wound is located on the side of the outer cover 6 corresponding to the position of the belt conveyor unit 2. A feed port 62 is located on the upper side of the outer cover 6 corresponding to the position of the winding unit 4. A winding workpiece outlet 63 is located on one side of the outer cover 6 corresponding to the position of the winding unit 4. A chute plate 9 is provided on the upper side of the base plate 1, corresponding to the position between the winding workpiece outlet 63 and the winding unit 4. A sensor mounting plate 7 is fixedly installed on the upper side of the base plate 1, corresponding to the position between the winding unit 4 and the clamping and rotating unit 5, and a sensor 8 is mounted on the sensor mounting plate 7.

[0036] The working principle and complete workflow of this invention are as follows:

[0037] Manual feeding: The worker places the part to be wound 10 on the belt conveyor unit 2 and starts the equipment. The belt conveyor unit 2 transports the part to be wound 10 to the end, where it is stopped by the baffle 22.

[0038] Material feeding unit picking up material: The first linear module 32 of the feeding unit 3 moves downward to the gripping height, and the electric claw 36 grips the workpiece 10 to be wrapped by the gripping fingers 37. Then, the first linear module 32 moves upward, and the first rotating table 34 drives the workpiece 10 to be wrapped to rotate 90° towards the clamping rotating unit 5 until the center of the workpiece 10 to be wrapped coincides with the center of the three-finger gripper 55.

[0039] Material receiving by clamping rotating unit: During the above rotation process, the second linear module 51 of clamping rotating unit 5 moves from the initial position toward the electric claw until the claw 56 can clamp the workpiece 10 to be wound.

[0040] Preparation for winding: After the gripper 56 clamps the workpiece 10 to be wound, the electric gripper 36 releases. The first linear module 32 of the feeding unit 3 moves upward, while the first rotary table 34 rotates 90° to return to its initial state. At the same time, the foam tape is manually fed through the feeding port 62 of the outer cover 6 for a certain distance and then released.

[0041] Winding operation: After sensor 8 detects the foam tape, the third linear module 41 moves the round bar 46 close to the part to be wound 10 until the closest distance between the outer surface of the part to be wound 10 and the outer surface of the round bar 46 is less than the thickness of the foam tape, and the initial horizontal plane of the round bar 46 is at the same height as the horizontal plane of the part to be wound 10. Then, the third rotary table 44 moves the disc 45 and the round bar 46 counterclockwise around the part to be wound 10. From the perspective of the three-finger gripper, after the rotation angle is greater than 180° (preferably about 200°), it quickly returns to the starting position and starts to rotate counterclockwise again. At the same time, the second rotary table 54 moves the three-finger gripper 55 counterclockwise (from the perspective of the three-finger gripper). After the round bar 46 rotates again by 180° (preferably about 200°), the third linear module 41 moves the round bar 46 slowly towards the first module, but the outer surface of the round bar 46 maintains a certain distance from the surface of the wrapped foam tape, ensuring that the round bar 46 applies a certain pressure to it during the tape winding process to prevent the tape from falling off.

[0042] Material feeding: After the tape is wrapped, the three-finger gripper 55 and the round bar 46 stop rotating. The second linear module 51 retracts to the feeding position, opens the gripper 56, and the wrapped finished product slides out through the chute plate 9 and the wrapping part outlet 63 of the outer cover 6. The third linear module 41 returns to the initial position, and the process ends.

[0043] In addition, to accommodate the high-temperature and easy-to-adhere properties of foam adhesive, the round bar 46 and the guide plate in contact with the foam tape are coated or pasted with a layer of anti-adhesion material, such as polytetrafluoroethylene, to prevent the foam tape from sticking to it during the winding process.

[0044] All of the above processes were completed under constant temperature conditions.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
