Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning equipment technology, specifically a rotating cleaning mechanism in an ultrasonic cleaning tank. Background Technology

[0002] An ultrasonic cleaner is a cleaning device based on the combined action of ultrasonic vibration and cleaning fluid. It utilizes the high-frequency vibration of ultrasound and the flow of cleaning fluid to quickly remove dirt, oil stains, and other impurities adhering to the surface of the workpiece, thereby achieving a highly efficient and thorough cleaning effect.

[0003] However, it is difficult to meet the particle size cleaning requirements of some products with high cleaning requirements. If used in an automated production line linked with a robotic arm and vision inspection system, in order to avoid uneven cleaning (such as striped residue), affecting the efficiency of vision inspection and reducing the automatic generation of the production line, it is necessary to propose a rotating cleaning mechanism in an ultrasonic cleaning tank. Utility Model Content

[0004] The purpose of this invention is to provide a rotating cleaning mechanism in an ultrasonic cleaning tank, so as to solve the above-mentioned technical problems to a certain extent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes an ultrasonic chamber, a drive motor fixedly mounted on one side of the ultrasonic chamber, ultrasonic generators mounted on both sides and the bottom of the ultrasonic chamber, an active shaft assembly and a passive shaft assembly respectively mounted at both ends of the ultrasonic chamber, an outer frame rotatably mounted inside the ultrasonic chamber, the active shaft assembly being driven by the drive motor, and the outer frame being supported by the active shaft assembly and the passive shaft assembly for rotating inside the ultrasonic chamber, an inner frame for gripping and cleaning products placed inside the outer frame, a top cover frame mounted above the inner frame, and U-shaped fixing rods slidably inserted into both sides of the top of the top cover frame, two adjustment holes symmetrical to the U-shaped fixing rods respectively opened on both sides of the outer frame, the adjustment holes being multiple longitudinally distributed circular holes, and one end of the U-shaped fixing rod being inserted into the outer frame through the adjustment hole.

[0006] Preferably, the drive shaft assembly includes a first mounting base fixedly disposed on the inner edge of the ultrasonic housing, a coupling disposed on the output end of the drive motor, a first bearing seat fixedly disposed on the first mounting base, and a drive connecting shaft rotatably disposed inside the first bearing seat and fixedly connected to the coupling and the outer frame edge.

[0007] Preferably, the passive shaft assembly includes a second mounting base fixedly disposed on the other side inside the ultrasonic chamber, a second bearing seat fixedly disposed on the second mounting base, and a passive connecting shaft rotatably connected to the other side of the outer frame at one end inside the second bearing seat.

[0008] Preferably, the two protruding parts on the top of the upper cover frame are respectively provided with through holes that match the U-shaped fixing rods, and the two ends of the U-shaped fixing rods are respectively inserted into the protruding parts on the top edge of the upper cover frame through the through holes.

[0009] Preferably, the outer wall edge of the ultrasonic chamber is provided with a drain pipe for draining internal water.

[0010] Preferably, two basket lifting shafts are fixedly installed on the upper sides of both sides of the outer frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In use, this utility model uses a drive motor to drive the active shaft assembly, causing the outer frame to rotate inside the ultrasonic chamber. The inner frame is placed below the outer frame and then placed on top of the inner frame by the upper cover frame. The U-shaped fixing rods that slide and insert on the protruding parts on both sides of the top of the upper cover frame constrain and fix the inner frame placed inside the outer frame. When the outer frame rotates, it causes the product in the inner frame to rotate inside the ultrasonic chamber. The ultrasonic generators set on both sides and bottom of the ultrasonic chamber cause the cleaning product to rotate dynamically. The ultrasonic waves penetrate from multiple angles, eliminating blind spots and dead angles (such as deep holes and threads) and rotating disturbance of the liquid, enhancing the impact force of cavitation bubble rupture, improving the dirt removal efficiency by 30%-70%, and avoiding uneven cleaning caused by the standing wave effect in fixed positions.

[0013] 2. When this utility model is used, the adjustment holes are multiple longitudinally distributed round holes, which can constrain and fix inner frames of different specifications, and are suitable for small parts and large workpieces respectively, thus improving space utilization; at the same time, the first bearing seat and the second bearing seat are bolted together, which facilitates the disassembly of the outer frame.

[0025] The outer frame 6 is supported and rotates inside the ultrasonic chamber 1 by the active shaft assembly 3 and the passive shaft assembly 4. The active shaft assembly 3 is driven by the drive motor 2, which drives the outer frame 6 to rotate inside the ultrasonic chamber 1. The inner frame 8 is placed inside the lower part of the outer frame 6 and then placed on top of the inner frame 8 by the upper cover frame 7. The U-shaped fixing rods 71, which are slidably inserted into the protruding parts on both sides of the top of the upper cover frame 7, are inserted into the adjustment holes 62 opened on the edge of the outer frame 6 to constrain and fix the inner frame 8 placed inside the outer frame 6. The adjustment holes 62 are multiple longitudinally distributed round holes, which can constrain and fix inner frames 8 of different specifications, and are suitable for cleaning products of different specifications. When the outer frame 6 rotates, it drives the product in the inner frame 8 to rotate inside the ultrasonic chamber 1. The ultrasonic generators 5, which are set on both sides and the bottom of the ultrasonic chamber 1, make the product rotate dynamically. The ultrasonic waves penetrate from multiple angles, eliminating blind spots and dead corners such as deep holes and threads. The rotation disturbs the liquid, enhances the impact force of cavitation bubble rupture, and improves the dirt removal efficiency by 30%-70%, avoiding uneven cleaning caused by the standing wave effect in the fixed position.

One end of the active connecting shaft 34 is connected to the coupling 32, and the other end is fixedly connected to the outer frame 6, so that the drive motor 2 drives the outer frame 6 to rotate. The first bearing seat 33 has a ball bearing shaft. The first bearing seat 33 is fixed to the first mounting base 31 by bolt installation, which facilitates the subsequent disassembly of the outer frame 6.

The passive connecting shaft 43 is supported by the second bearing seat 42, which is bolted to the second mounting base 41.

The two ends of the U-shaped fixing rod 71 are threaded, and the two ends of the U-shaped fixing rod 71 can be fixed by nuts to prevent the U-shaped fixing rod 71 from coming off during rotation.

[0032] In a further preferred embodiment, a drain pipe 9 for draining internal water is provided on the outer edge of the ultrasonic chamber 1.

[0033] The drain pipe 9 installed on the outer wall of the ultrasonic chamber 1 is used to drain water from the ultrasonic chamber 1.

[0035] The basket lifting shafts 61 provided on both sides of the outer frame 6 facilitate the removal of the outer frame 6 from the ultrasonic chamber 1 after disassembly.
