TECHNICAL FIELD

[0001] The application belongs to the technical field of polishing devices, and particularly relates to a robot seat arm polishing device. BACKGROUND

[0002] Large castings are key structural components in the industrial fields of heavy machinery, ships, power equipment, etc. In the casting production process, due to the need for mold gap and pouring system, flash, burrs and residual tumors will be formed at the parting surface and pouring riser after the casting is demolded. These irregular parts must be removed before entering the finishing and assembly, and the traditional rough polishing method mainly has the following problems:

[0003] The working environment is poor, and the health and safety risk is great: the polishing process produces high-concentration metal dust and huge noise, which seriously endangers the health of the operators. At the same time, the handheld heavy tool is operated at a high place, and there are high-falling, tool falling off, and mechanical injury risks such as flying debris.

[0004] It is difficult to collect dust, and the environmental protection pressure is great: due to the fixed polishing point, the traditional fixed dust collection system is difficult to effectively cover the entire operation area, resulting in workshop dust diffusion, environmental pollution, and increased enterprise management cost. SUMMARY

[0005] To achieve the above purpose, the application provides the following technical scheme: a robot seat arm polishing device, comprising: a soundproof and dustproof room, characterized in that the soundproof and dustproof room is divided into an upper operation room and a lower function room by a horizontally arranged partition;

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] This invention relates to a robot arm grinding device, such as... Figures 1-4 As shown, the system includes a soundproof and dustproof room 1. The soundproof and dustproof room 1 is characterized by being divided into an upper operating room 14 and a lower functional room 3 by a horizontally arranged partition. The operating room 14 contains a grinding robot arm 5 and an operating table 6 for fixing workpieces. A material discharge hole is provided in the partition area corresponding to the area below the operating table 6. A material collection bin 12 located in the functional room 3 is provided below the material discharge hole. The functional room 3 contains a first dust removal system, and the top of the soundproof and dustproof room 1 contains a second dust removal system. The first dust removal system includes a dust suction device connected to the material collection bin 12, and the second dust removal system includes an air outlet device. The first and second dust removal systems together form a top-to-bottom airflow organization within the operating room 14.

[0031] The installation of this embodiment follows the sequence from the main structure to the internal systems:

[0032] Step 1: Installation of the room body and partitions. First, construct the frame and wall panels of the soundproof and dustproof room 1. Then, weld or bolt the first mounting plate 11 and the second mounting plate 7 to the predetermined height. Together, they form a horizontal partition, firmly dividing the room body into the operating room 14 and the functional room 3.

[0033] Step 2: Equipment Installation in the Control Room. Inside the control room 14, the bases of the two grinding robotic arms 5 are fixed to the first mounting plates 11 on both sides, and mechanical and electrical adjustments are made. At the same time, the control panel 6 is hoisted and fixed to the second mounting plate 7 in the middle, ensuring that its position is centered and stable.

[0034] Step 3: Functional room system integration.

[0035] Hoist the bucket-shaped collection bin 12 into the functional chamber 3, aligning its top opening with the material drop hole area on the second mounting plate 7, and seal it by welding or adding a sealing strip to prevent dust leakage.

[0036] The vacuum cleaner 13 is placed on one side of the soundproof and dustproof room, and its inlet is connected to the outlet at the lower part of the side wall of the collection bin 12 through a connecting pipe. All pipe connections are made airtight.

[0037] Step 4: Top System Installation. Install the static pressure box 8 on the top of the soundproof and dustproof room 1, with its air outlet 9 facing the operating room 14. The first fan 10 can be installed on the outer side of the top of the functional room 3, and connected to the static pressure box 8 through the air inlet pipe passing through the roof.

[0038] Step 5: Pipeline connection. Connect the inlet 16 to the workshop water supply system via a valve; lead the outlet 15 to the workshop drainage ditch or a dedicated sedimentation tank via a pipe.

[0039] Workflow:

[0040] Loading and Grinding: The operator opens the sliding door 2 via the control panel and uses a crane or AGV to transport the large casting to the operating table 6, where it is locked with clamps. After closing the sliding door 2, the system starts automatically. The first fan 10 runs, and clean air is evenly delivered downwards from the air outlet 9 after being balanced by the static pressure box 8; at the same time, the vacuum cleaner 13 starts, generating suction at both the inlet of the collection bin 12 and the air outlet 17 of the functional chamber. A stable downward airflow curtain is formed in the operating chamber 14. At this time, the grinding robotic arm 5 grinds the casting according to the preset program, and the generated dust is firmly suppressed by the airflow and carried into the collection bin 12.

[0041] Workpiece cleaning: The grinding process ends, and robotic arm 5 resets. The first fan 10 runs continuously or with increased intensity for about 30-60 seconds, and the strong clean airflow sweeps the surface of the casting to completely remove the residual dust. The dust is carried by the airflow into the collection bin through the discharge hole.

[0042] Material unloading and circulation: After dust removal is completed, the system prompts that the operation is complete. The operator opens sliding door 2, unloads the processed workpiece, loads a new workpiece, and repeats steps S1-S3.

[0043] Collection bin cleaning (intermittent): After the system has been running for a period of time (such as after a shift), the operator initiates the flushing procedure. The control panel opens the inlet valve, and pressurized water is injected from the high-level inlet 16, forming a rapid flow along the sloping bottom of the bin. This washes away the deposited metal debris to the low-level outlet 15, and finally discharges it into the sedimentation tank for solid-liquid separation. The water supply is turned off after flushing is complete.

[0044] Design effects and advantages: This embodiment constructs a closed dust treatment cycle through "top-suction and bottom-suction" airflow organization and negative pressure design of the functional chambers. The operating chamber is the main dust removal area, while the functional chambers serve as the safety and collection areas.

[0045] Source capture and efficient dust removal: The top-down airflow can effectively suppress dust diffusion, controlling and guiding dust away near the dust generation point, with a dust removal efficiency of over 95%.

[0046] Preventing secondary pollution: The air outlet 17 of the functional room can actively suck up the fine dust raised by the impact of falling materials, ensuring the cleanliness of the functional room, avoiding the risk of maintenance personnel being hit by dust when opening the door, and also protecting other equipment in the functional room.

[0047] Online dust removal improves efficiency: The workpiece is cleaned before leaving the chamber, eliminating the need for a separate cleaning process and improving overall operational efficiency.

[0048] Automated maintenance: The automatic water flushing design of the collection bin transforms the heavy manual cleaning work into a simple automatic operation, greatly reducing labor intensity and equipment downtime.

[0049] Example 2:

[0050] Installation details (differences from Embodiment 1): The main difference between Embodiment 1 and Embodiment 1 is the dust collection structure inside the collection bin 12. When installing the internal components of the collection bin 12, two dust collection branch pipes with pre-drilled air inlets are first arranged in parallel about 10-2 cm above the bottom of the collection bin 12 and fixed with pipe clamps.

[0051] Use a tee fitting to connect one end of the two vacuum cleaner branch pipes together, and then connect them to the inlet of the vacuum cleaner 13 through a connecting pipe. Seal the other end of the two branch pipes tightly with end caps. The remaining installation steps are exactly the same as in Example 1.

[0052] Workflow: The workflow is basically the same as in Example 1. The key difference lies in the suction process: When the vacuum cleaner 13 is started, negative pressure acts simultaneously on both suction pipes. The negative pressure suction is released through numerous air inlets distributed on the pipes, forming a large-area, uniform negative pressure field across the entire cross-section of the collection bin 12. This ensures that both heavy metal particles and light dust are quickly and evenly adsorbed after falling into the collection bin, preventing accumulation in certain areas due to insufficient suction.

[0053] Design effects and advantages: By using distributed suction branch pipes, the "single-point strong suction" is improved into "wide-area uniform suction", which greatly optimizes the flow field distribution inside the collection bin.

[0054] Eliminating adsorption dead zones: This solves the problem of weak suction in the corner areas of large collection bins, ensuring that dust in all areas of the bin, especially easily airborne light dust, can be effectively captured, and the dust collection efficiency is improved by about 15%-30% compared to Example 1.

[0055] Improved system stability: Uniform adsorption force avoids localized dust accumulation in the silo, reduces the risk of blockage in the collection silo, and makes the entire dust removal system operate more stably and reliably.

[0056] Enhanced compatibility: It is particularly suitable for grinding large castings with wider worktables and a wider dust generation range, demonstrating better process adaptability.

[0057] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
