Description

Technical Field

[0001] This utility model relates to the field of fully automatic bare capacitor cleaning technology, and in particular to a shock-absorbing and protective device for a fully automatic ultrasonic cleaning machine for bare capacitors. Background Technology

[0002] With the widespread adoption of fully automated production lines for bare capacitors, ultrasonic cleaning machines face the problem of equipment damage caused by severe vibration transmission during continuous operation. Common shock absorption devices used in ultrasonic cleaning machines are mostly integral rubber pads or spring structures. Because they are made of a single material, they cannot simultaneously absorb high-frequency vibrations and buffer impact loads, resulting in insufficient attenuation efficiency. Furthermore, because this type of structure is a single unit, the entire unit must be replaced when partial damage occurs, leading to long downtime. In addition, fixed bases cannot compensate for uneven ground surfaces, easily causing vibration to worsen due to support imbalance. Moreover, the ultrasonic waves generated by the cleaning machine are reflected multiple times within the sealed cavity, causing resonance noise. Existing solutions using multi-layered steel plates for shock absorption, while improving rigidity, exacerbate the transmission of high-frequency vibrations. Some solutions using magnetic fluid shock absorbers are costly and lack modular maintenance. Therefore, there is an urgent need for a shock absorption and protection device for fully automated ultrasonic cleaning machines for bare capacitors. Utility Model Content

[0003] The purpose of this utility model is to address the deficiencies in the existing technology by proposing a shock-absorbing and protective device for a fully automatic ultrasonic cleaning machine for bare capacitors.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A shock-absorbing and protective device for a fully automatic ultrasonic cleaning machine for bare capacitors includes: a top connecting plate, which is a square metal plate with protrusions at the four corners and bolt holes at the center of each protrusion;

[0006] The bottom box has a composite edging, and the bottom of the bottom box has a cross-shaped reinforcing rib and a flow guide cavity, with the flow guide cavity located on the cross-shaped reinforcing rib.

[0007] Four sets of adjustable support feet are installed at the four bottom corners of the bottom housing via adjusting screws;

[0008] Four sets of mounting claw modules are symmetrically connected to the four corners of the top connecting plate and the bottom housing.

[0009] Furthermore, the mounting claw module includes: an upper claw: an inverted L-shaped spring steel sheet, with one vertical section facing upward to cooperate with the boss, and one horizontal section extending towards the center of the top connecting plate, and having a concave dovetail groove;

[0010] The lower claw is an L-shaped spring steel sheet. The vertical section two is connected to the bottom box body by an inclined vertical plate, and the horizontal section two extends to the outside of the top connecting plate and is provided with a convex dovetail tenon.

[0011] The interlocking gap between the dovetail groove and the dovetail tenon is filled with silicone blocks.

[0012] Furthermore, the composite edging comprises, from the outside to the inside, an outer layer, a damping intermediate layer, and a perforated inner layer. The damping intermediate layer has a plurality of circular holes evenly distributed on it, and rubber particles are injected into the damping intermediate layer. The density of the silicone block decreases sequentially from the outside to the inside.

[0013] Furthermore, the flow guiding cavity includes several radial grooves and an embedded copper tube, the copper tube having an internal hollow structure and being filled with magnetic particles.

[0014] Furthermore, the copper tube has a U-shaped structure, is wrapped with a silicone sleeve, and its two ends are connected to the damping intermediate layer.

[0015] Furthermore, the adjusting screw penetrates the bottom of the bottom housing.

[0016] Furthermore, the bottom chamber is filled with sound-absorbing sponge, which is composed of alternating layers of closed-cell sponge and open-cell sponge, with stainless steel wire mesh sandwiched between the two layers.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] By employing a dovetail interlocking structure with an inverted L-shaped upper claw and a regular L-shaped lower claw, vertical vibration is decomposed into oblique shear force. During this process, high-frequency micro-vibrations are absorbed by gradient density silicone blocks, and the low-hardness central area of ​​the gradient density silicone blocks can buffer peak impacts, achieving step-like energy dissipation. A spatial gradient attenuation barrier is formed by using a three-layer composite edging structure. In addition, magnetic particles are placed inside the U-shaped copper tube. During use, collisions and friction generate heat, and eddy currents are generated by cutting magnetic lines of force, achieving mixed energy dissipation. The four sets of mounting claw modules can be independently disassembled and replaced, shortening maintenance time. This system is particularly suitable for high-frequency start-stop and continuous impact conditions in fully automated production lines. Attached Figure Description

[0030] The bottom box 2 is provided with a composite edging 21, and the bottom of the bottom box 2 is provided with a cross reinforcing rib 22 and a flow guiding cavity 25, wherein the flow guiding cavity 25 is provided on the cross reinforcing rib 22.

[0031] Four sets of adjustable support feet 26 are installed at the four bottom corners of the bottom housing 2 via adjusting screws 261;

[0032] Four sets of mounting claw modules 3 are symmetrically connected to the four corners of the top connecting plate 1 and the bottom box 2. In one specific implementation, the top connecting plate 1 is made of aluminum alloy and is made into a square plate. The four corners are welded with protrusions 11 that are higher than the plate surface. Bolt holes are drilled in the center of the protrusions. The bottom box 2 is formed by welding steel plates. The edges are surrounded by composite edging 21. The bottom is welded with cross reinforcing ribs 22 of sufficient thickness. The guide cavity 25 is milled out on the rib plate.

[0033] Four sets of adjustable support feet 26 are fixed to the four corners of the box by adjusting screws 261, and anti-slip pads are added to the bottom of the screws;

[0034] Four sets of mounting claw modules 3 are symmetrically installed between the four corners of the top connecting plate 1 and the bottom box 2;

[0035] When the equipment is running, ultrasonic vibration is transmitted to the mounting claw module 3 through the top connecting plate 1. The vibration energy is decomposed by the elastic claw and then transmitted to the bottom box 2. The adjustable support foot 26 adapts to the unevenness of the ground through the adjusting screw 261 to ensure the overall stability of the device.

[0036] The mounting claw module 3 includes: an upper claw 31, which is an inverted L-shaped spring steel sheet, with a vertical section 311 facing upward and cooperating with the boss 11, and a horizontal section 312 extending towards the center of the top connecting plate 1, and having a concave dovetail groove 313.

[0037] Lower claw 32: It is a positive L-shaped spring steel sheet. The vertical section 321 faces downward and is connected to the bottom box 2 through the inclined vertical plate 24. The horizontal section 322 extends outward to the top connecting plate 1 and is provided with a convex dovetail tenon 323.

[0038] The interlocking gap between the dovetail groove 313 and the dovetail tenon 323 is filled with a gradient density silicone block 33, the density of which decreases from the outside to the inside.

[0039] The composite edging 21 comprises, from the outside to the inside, an outer layer 211, a damping intermediate layer 212, and a perforated inner layer 213. The damping intermediate layer 212 has a plurality of evenly distributed circular holes 212a, and rubber granules 212b are injected into it. In one specific embodiment, the vertical section 311 of the upper claw 31 is vertically locked to the boss 11 by bolts, and the horizontal section 312 extends towards the center. The vertical section 321 of the lower claw 32 is welded to the bottom housing 2. The inclined vertical plate 24 has horizontal section 322 extending outward, and the composite edging 21 has vertical corrugated grooves stamped on its surface; butyl rubber granules 212b are injected into the round holes 212a of the damping intermediate layer 212, and carbon fiber cloth is pasted on the back of the perforated inner layer 213. When the vibration energy passes through the mounting claw module 3, the dovetail structure of the upper claw 31 and the lower claw 32 generates oblique shear force. The silicone block 33 is a silicone block with gradient density, whose outer layer absorbs high-frequency vibration and the center buffers peak impact.

[0040] In addition, the outer layer 211 of the composite edging 21 disperses stress, the rubber particles 212b of the middle layer 212 dissipate energy through friction, and the perforated inner layer 213 reflects residual sound waves.

[0041] The flow guiding cavity 25 includes a plurality of radial grooves 251 and an embedded copper tube 252, wherein the copper tube 252 has an internal hollow structure and is filled with magnetic particles.

[0042] The copper tube 252 has a U-shaped structure and is wrapped with a silicone sleeve. Both ends of the copper tube 252 are connected to the damping intermediate layer 212. In one specific embodiment, the radial grooves 251 of the flow guiding cavity 25 radiate outwards from the center of the cross-shaped reinforcing rib 22, with the U-shaped copper tube 252 embedded along the groove path. Both ends of the copper tube 252 are welded to the damping intermediate layer 212 of the composite edging, forming a conductive circuit. When vibrational energy is transmitted into the flow guiding cavity 25, the magnetic particles inside the copper tube 252 collide and rub against each other due to vibration, simultaneously cutting magnetic field lines to generate eddy currents, converting mechanical energy into heat energy. The silicone sleeve suppresses copper tube resonance, and the conductive circuit enhances the electromagnetic damping effect.

[0043] The adjusting screw 261 penetrates the bottom of the bottom housing 2, and the top of the adjusting screw 261 is connected to the hydraulic damper via a ball joint.

[0044] The bottom housing 2 is filled with sound-absorbing sponge 23, which is composed of alternating layers of closed-cell sponge 231 and open-cell sponge 232, with stainless steel wire mesh 233 sandwiched between the two layers. In one specific embodiment, the adjusting screw 261 of the adjusting support foot 26 has a knurled anti-slip surface, and the top is connected to a hydraulic damper through a ball joint to adjust the stroke. The sound-absorbing sponge 23 is composed of alternating layers of closed-cell sponge 231 and open-cell sponge 232, with stainless steel wire mesh 233 sandwiched between the layers. The adjusting screw 261 adjusts the support height by rotating, so that the four corner mounting claw modules 3 are evenly stressed. In the sound-absorbing sponge 23, the closed-cell sponge 231 blocks high-frequency sound waves, the open-cell sponge 232 absorbs mid- and low-frequency vibrations, and the stainless steel wire mesh 233 blocks the sound wave diffraction path.
