Description

Technical Field

[0001] The present invention relates to the technical field of frame assembly devices, and in particular to a frame assembly device for a sound barrier. Background Art

[0002] A sound barrier is a device designed to block the spread of noise. It is typically installed between the noise source and the protected area to reduce noise interference with the surrounding environment and people. It reduces noise transmission through reflection, absorption, and diffraction attenuation, and is widely used in transportation, industry, construction, and other fields.

[0003] In sound barrier manufacturing, glass wool is often used as a sound insulation material. Glass wool has a high sound absorption coefficient, effectively absorbing and attenuating the propagation of sound waves. Its complex internal fiber structure causes sound waves to reflect and scatter multiple times between the fibers, thereby reducing the propagation energy of the sound waves.

[0004] The prior art has the following deficiencies:

[0005] 1. Most sound barriers are assembled manually. Manual operation is easily affected by factors such as fatigue and rest, making it difficult to achieve continuous production, resulting in low production efficiency. During the installation process, workers need to frequently move and install components, which is labor-intensive and lacks safety.

[0006] 2. The production process mostly uses artificial filling of glass wool. The speed of artificial filling is relatively slow and it is difficult to meet the needs of large-scale sound barrier production. The fibers of glass wool are easily broken and produce dust during the filling process. Long-term exposure of workers to it will cause respiratory diseases. Summary of the Invention

[0034] Symmetrical fixing seats 104 are fixedly installed on the upper surfaces of the two upper slides 103, and an electric push rod 105 is fixedly installed on the lower end of each fixing seat 104. Every two adjacent electric push rods 105 are arranged at a 45° angle, and the upper slide 103 close to the side of the horizontal push rod 101 is located at the upper end of the through slot 13.

A connecting rod 208 is rotatably installed at one end of the lower surface of the rotating arm 206. Clamps 209 are fixedly installed on both sides of the lower end of the connecting rod 208.

[0037] like Figure 7 As shown, the mobile cutting mechanism includes a mobile motor 303 fixedly installed on the upper end of the cutting table 301, a hanging arm 305 is slidably installed on the output end of the mobile motor 303, and a cutting blade 306 is rotatably installed on the lower end of the hanging arm 305. A feed port 302 is fixedly installed at the rear end of the cutting table 301, and a roller 304 is rotatably installed inside the cutting table 301. The glass wool is pre-treated according to production requirements, and then the glass wool is placed inside the feed port 302 at the rear end of the cutting table 301. The glass wool is input to one end of the interior of the equipment through the roller 304 and is set according to the length of the internal installation groove of the sound barrier. The mobile motor 303 drives the cutting blade 306 to cut the glass wool for filling.

[0038] like Figure 8As shown, the pushing mechanism includes a material storage trough 401 fixedly mounted on the lower surface of the base 1, an inner slide groove 404 is opened inside the material storage trough 401, and hydraulic rods 402 are fixedly mounted on the four corners of the bottom of the material storage trough 401. The output end of each hydraulic rod 402 passes through the lower surface of the material storage trough 401 and a push plate 403 is fixedly mounted. The push plate 403 moves up and down along the inner slide groove 404 through the hydraulic rod 402. A feeding trough 6 is fixedly mounted on the outer surface of the base 1, and the feeding trough 6 is connected to the interior of the material storage trough 401. Before processing, the outer frame of the sound barrier is transported to the interior of the material storage trough 401 through the feeding trough 6, and the hydraulic rod 402 transports the outer frame upward for processing according to operation requirements.

[0039] Working principle: Inside the base 1 of the equipment, a pushing mechanism is fixedly installed at the lower end of the through groove 13. The core of the pushing mechanism is the storage trough 401, which is the material storage center of the entire equipment. An inner chute 404 is provided inside the storage trough 401 to guide the movement of the push plate 403. Hydraulic rods 402 are fixedly installed at the four corners of the bottom of the storage trough 401, and the output end of each hydraulic rod 402 passes through the lower surface of the storage trough 401 and a push plate 403 is fixedly installed. The push plate 403 moves up and down along the inner chute 404 through the hydraulic rod 402 to realize the pushing operation of the material. Before the frame assembly process, the operator first puts the outer frame of the sound barrier into the storage trough 401 through the feeding trough 6. The feeding trough 6 is connected to the inside of the storage trough 401, and the design is ingenious, which makes it convenient for the operator to quickly put in materials. When the outer frame enters the storage trough 401, the hydraulic rod 402 is activated according to the operation requirements, pushing the push plate 403 to move upward along the inner chute 404. The rising of the push plate 403 pushes the outer frames one by one to the same height of the operation panel 10, so as to prepare for subsequent transportation and processing.

[0040] When the outer frame is pushed to the same height as the operating panel 10, the workpiece conveying mechanism starts working. The workpiece conveying mechanism is fixedly mounted on the upper surface of the operating panel 10, and its main components include a slide rail 11, an upper slide 103, a drive motor 8, a horizontal push rod 101, and a connecting push rod 102. The slide rail 11 provides a stable sliding path for the upper slide 103, ensuring the stability of the outer frame during the conveying process. The drive motor 8 is fixedly mounted on one side of the operating panel 10, and a horizontal push rod 101 is fixedly mounted on the upper end of the hanging platform 7 on the other side. The output end of the horizontal push rod 101 passes through the limit table 9 and is slidably mounted with a connecting push rod 102, and one end of the connecting push rod 102 is fixedly mounted with the upper slide 103. After the drive motor 8 is started, it drives the upper slide 103 to move along the slide rail 11. The movement of the upper slide 103 is transmitted through the connecting push rod 102, and finally pushes the outer frame to move along the slide rail 11 to the middle position of the equipment. Symmetrical mounting blocks 104 are fixedly mounted on the upper surface of the upper slide 103. An electric push rod 105 is fixedly mounted at the lower end of each mounting block 104. The push rods 105 can be adjusted according to the length of the outer frame, ensuring stability and accuracy during conveying. The upper slide 103, located near the side of the horizontal push rod 101, is located at the upper end of the through slot 13. This design allows the outer frame to smoothly transition from the material storage trough 401 to the workpiece conveying mechanism, achieving continuous material conveying.

[0041] A cross arm 3 is fixedly installed on the upper end of the column 2, and a rotating base 202 is slidably installed between the two cross arms 3. A clamping claw 209 for grasping and adjusting the position is provided on one side surface of the rotating base 202. The telescopic rod 203 is controlled according to the processing position, and multiple rotating motors 205 located between the support arm 204 and the rotating arm 206 are controlled so that the clamping claw 209 can adjust the position of the outer frame for easy processing.

[0042] At this time, the drive motor 8 located on the other side of the operation panel 10 starts to work, and the drive motor 8 drives the upper slide 103 to move. The electric push rod 105 located on the upper slide 103 pushes according to the length of the outer frame, and the two upper slides 103 cooperate to fix the position of the outer frame.

[0043] When the outer frame is transported to the middle position of the operating panel 10, the rotating robotic arm mechanism starts working to precisely adjust the position of the outer frame. The rotating robotic arm mechanism is slidably mounted on the upper end of the mobile cutting mechanism, and its core components include a telescopic rod 203, a rotating base 202, a turntable 207, a support arm 204, a rotating arm 206, and a clamp 209. The telescopic rod 203 is fixed to the upper end of the slider 201, and its output end passes through the slider 201 and is fixedly mounted with a rotating base 202. A turntable 207 is fixedly mounted on one side surface of the rotating base 202, and the turntable 207 is rotatably mounted with the support arm 204, and one end of the support arm 204 is rotatably mounted with the rotating arm 206. Rotating motors 205 are rotatably mounted at the connection between the turntable 207 and the support arm 204, as well as at the connection between the support arm 204 and the rotating arm 206. These rotating motors 205 provide power for the multi-degree-of-freedom movement of the robotic arm.

[0044] A connecting rod 208 is rotatably mounted on one end of the lower surface of the rotating arm 206, and clamps 209 are fixedly mounted on both sides of the lower end of the connecting rod 208. The clamps 209 are the key executive components of the rotating robotic arm mechanism, and are used to clamp the outer frame of the sound barrier. When the outer frame reaches the specified position, the clamps 209 are activated to firmly clamp the outer frame. At this time, according to the requirements of the processing position, the control system issues instructions to control the telescopic rod 203 to perform telescopic movements. At the same time, multiple rotating motors 205 work together to drive the turntable 207, the support arm 204 and the rotating arm 206 to perform precise angle adjustments. Through this series of actions, the outer frame is adjusted to the optimal processing position, ready for the subsequent glass wool filling and cutting processes.

[0045] In the manufacturing process of sound barriers, the cutting and filling of glass wool is one of the key steps. The frame device realizes the automation and precision of this process through the mobile cutting mechanism. The mobile cutting mechanism is fixedly installed at the upper end of the workpiece conveying mechanism, and its core components include a cutting table 301, a mobile motor 303, a hanging arm 305, a cutting blade 306, a feed port 302 and a roller 304. The cutting table 301 is fixedly installed on the cross rail 12 at the outer end between the two limit tables 9, and the cross rail 12 provides a stable sliding path for the cutting table 301. The mobile motor 303 is fixedly installed on the upper end of the cutting table 301, and the hanging arm 305 is slidably installed on the output end of the mobile motor 303. The cutting blade 306 is rotatably installed at the lower end of the hanging arm 305. The feed port 302 is fixedly installed at the rear end of the cutting table 301, and the roller 304 is rotatably installed inside. These components work together to ensure the efficiency and precision of the cutting and filling process of the glass wool.

[0046] Before cutting the glass wool, the operator pre-treats the glass wool according to the length of the internal installation groove of the sound barrier. The pre-treated glass wool is placed inside the feed port 302 at the rear end of the cutting table 301. Driven by the equipment, the roller 304 begins to rotate, feeding the glass wool into one end of the equipment. When the glass wool reaches the cutting area, the mobile motor 303 starts according to the set parameters, driving the cutting blade 306 to move and cut along the hanging arm 305. The precise cutting of the cutting blade 306 ensures that the size of the glass wool meets the requirements of the internal installation groove of the sound barrier. The cut glass wool falls into the outer frame of the sound barrier under the action of gravity, completing the filling process. The design of the mobile cutting mechanism allows the cutting length of the glass wool to be flexibly adjusted according to the actual needs of the sound barrier. Through precise motor control and high-speed rotation of the cutting blade 306, the cutting quality of the glass wool is effectively guaranteed. At the same time, the automated filling process reduces errors in manual operation and improves the overall quality and production efficiency of the sound barrier.
