Description

Technical Field

[0001] This utility model relates to the field of megasonic cleaning machine technology, and in particular to a workpiece cooling mechanism for a megasonic cleaning machine. Background Technology

[0002] Megasonic cleaning machines have been widely used in the industrial cleaning field. Megasonic waves are high-frequency sound waves with frequencies between 800kHz and 1MHz. Their cleaning principle utilizes high-frequency vibrations to generate countless tiny cavitation bubbles in the cleaning fluid. When these cavitation bubbles come into contact with the workpiece surface, they burst instantly, generating a powerful impact force that removes dirt, particles, and other impurities from the workpiece surface.

[0003] However, during mega-sonic cleaning, the transfer of acoustic energy causes the cleaning fluid temperature to rise. This is mainly because the mechanical energy of the acoustic waves is partially converted into heat energy in the cleaning fluid. Especially during long-term, high-intensity cleaning operations, the temperature rise of the cleaning fluid is more significant. For some temperature-sensitive workpieces, high temperatures may cause workpiece deformation and also alter the physicochemical properties of the cleaning fluid, affecting the cleaning quality. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a workpiece cooling mechanism for a megasonite cleaning machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a workpiece cooling mechanism for a megasonic cleaning machine, comprising a receiving frame and a support. A coolant tank is fixedly connected to the lower center of the receiving frame, and the coolant tank is fixedly connected to the upper side of the support. A circulating cooling assembly is provided on the outer side of the coolant tank. The circulating cooling assembly includes a single heat-absorbing assembly and a circulating assembly. Multiple sets of single heat-absorbing assemblies are arranged in a ring array on the outer side of the circulating assembly, and multiple sets of single heat-absorbing assemblies are simultaneously attached to the inner side of the receiving frame. Each single heat-absorbing assembly includes a connecting seat, a double-folded tube, a connecting pipe, and fins. Multiple sets of fins are parallel to each other and sleeved on the outer side of the double-folded tube. The upper edge of the fins contacts the inner wall of the receiving frame. The connecting seat is snapped onto the outer ring surface of the double-folded tube. One end of the double-folded tube is fixedly connected to the circulating assembly through the connecting pipe, and the other end of the double-folded tube is fixedly connected to the coolant tank.

[0006] Preferably, the circulation assembly includes a ring pipe, an input pipe, a cylindrical shell, a motor, an output pipe, a fan wheel, and a side cover. The ring pipe is located outside the coolant reservoir and is simultaneously fixedly connected to multiple sets of connecting pipes.

[0007] Preferably, the input pipe is fixedly connected to the bottom of the coolant tank, and the input pipe is fixedly connected to the cylindrical shell.

[0008] Preferably, the motor is fixedly connected to the middle of one side of the cylindrical shell, and the output shaft of the motor extends into the inner cavity of the cylindrical shell.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by installing the mechanism inside a mega-sonic cleaning machine, the workpiece is fixed on the upper surface of the receiving frame. The cleaning fluid, in conjunction with the sonic waves, cleans the workpiece. The circulation component distributes the coolant with a lower temperature from the coolant tank to multiple sets of connecting pipes, which then enter the corresponding double-folded pipes. Multiple sets of fins on the outside of the double-folded pipes are attached to the inner wall of the receiving frame. The heat of the workpiece is transferred to the fins through the receiving frame, absorbed by the coolant with a lower temperature inside the double-folded pipes, and returned to the coolant tank to restore the initial temperature and continue to participate in the circulation process. A certain amount of coolant is injected into the coolant tank to maintain the cooling effect for a period of time, thereby achieving the transfer of heat from the workpiece, preventing the workpiece from overheating and deforming during the cleaning process, and ensuring the cleaning quality.

[0014] 2. In this utility model, by controlling the motor to start, the motor drives the fan wheel to rotate inside the column housing. The middle part of the column housing is an annular cavity. The coolant stored in the coolant tank enters from the inlet of the column housing through the bottom inlet pipe. The middle part of the fan wheel is in contact with the middle part of the column housing, and the edge of the fan wheel is located in the annular cavity. The fan wheel rotates counterclockwise, in the same direction as the coolant entering the annular cavity of the column housing, accelerating the coolant into the annular cavity and discharging it from the outlet of the column housing. It then enters the ring pipe through the outlet pipe. Under the continuous pushing action, the coolant is distributed to multiple sets of individual heat absorption components to ensure stable circulation of the coolant. Attached Figure Description

A circulating cooling assembly 3 is arranged on the outer side of the coolant tank 2.

Multiple sets of individual heat-absorbing components 31 are arranged in a ring array on the outer side of the circulating assembly 32, and the multiple sets of individual heat-absorbing components 31 are simultaneously attached to each other. Inside the receiving frame 1, the single heat absorption component 31 includes a connecting seat 311, a double-fold tube 312, a connecting pipe 313, and fins 314. Multiple sets of fins 314 are parallel to each other and sleeved on the outside of the double-fold tube 312. The upper edge of the fins 314 contacts the inner wall of the receiving frame 1. The connecting seat 311 is snapped onto the outer ring surface of the double-fold tube 312. One end of the double-fold tube 312 is fixedly connected to the circulation component 32 through the connecting pipe 313, and the other end of the double-fold tube 312 is fixedly connected to the coolant tank 2.

[0024] The specific setup and function of this embodiment are described below: By installing this mechanism inside the mega-sonic cleaning machine, the workpiece is fixed on the upper surface of the receiving frame 1. The cleaning fluid, in conjunction with the sonic waves, cleans the workpiece. The circulation component 32 distributes the coolant with a lower temperature from the coolant tank 2 to multiple sets of connecting pipes 313, which then enter the corresponding double-fold pipes 312. Multiple sets of fins 314 on the outside of the double-fold pipes 312 are attached to the inner wall of the receiving frame 1. The heat of the workpiece is transferred to the fins 314 through the receiving frame 1, absorbed by the coolant with a lower temperature inside the double-fold pipes 312, and returned to the coolant tank 2 to restore the initial temperature and continue to participate in the circulation process. A certain amount of coolant is injected into the coolant tank 2 to maintain the cooling effect for a period of time, thereby achieving the transfer of heat from the workpiece, preventing the workpiece from overheating and deforming during the cleaning process, and ensuring the cleaning quality.

[0025] Example 2: Figure 1 - Figure 5 As shown, the circulation assembly 32 includes a ring pipe 321, an input pipe 322, a cylindrical housing 323, a motor 324, an output pipe 325, a fan 326, and a side cover 327. The ring pipe 321 is located outside the coolant reservoir 2 and is fixedly connected to multiple sets of connecting pipes 313. The input pipe 322 is fixedly connected to the bottom of the coolant reservoir 2 and is fixedly connected to the cylindrical housing 323. The motor 324 is fixedly connected to the middle of one side of the cylindrical housing 323, and the output shaft of the motor 324 extends into the inner cavity of the cylindrical housing 323. The middle of one side of the fan 326 is attached to the middle of the cylindrical housing 323 and is fixedly installed on the output shaft of the motor 324. The output pipe 325 is fixedly connected to the output end of the cylindrical housing 323 and is fixedly connected to the ring pipe 321. The side cover 327 is fixedly connected to the other side of the cylindrical housing 323 by screws, and the middle of one side of the side cover 327 is attached to the middle of the other side of the fan 326.

[0026] The overall effect of this embodiment is that by controlling the start of the motor 324, the motor 324 drives the fan 326 to rotate inside the cylindrical housing 323. The central part of the cylindrical housing 323 is an annular cavity, such as... Figure 5 The coolant stored inside the coolant tank 2 enters through the inlet of the cylindrical shell 323 via the bottom inlet pipe 322. The middle part of the fan 326 is in contact with the middle part of the cylindrical shell 323, and the edge of the fan 326 is located in the annular cavity. The fan 326 rotates counterclockwise, in the same direction as the coolant entering the annular cavity of the cylindrical shell 323, accelerating the coolant into the annular cavity and discharging it from the outlet of the cylindrical shell 323. It then enters the ring pipe 321 through the outlet pipe 325. Under the continuous pushing action, the coolant is distributed to multiple sets of individual heat absorption components 31 to ensure stable circulation of the coolant.

[0027] The device's operation and working principle are as follows: This mechanism is installed inside a mega-sonic cleaning machine. Support 4 connects to the machine's drive unit. The workpiece is fixed to the upper surface of the receiving frame 1. The cleaning fluid, combined with sonic waves, cleans the workpiece. At this time, the control motor 324 starts, driving the fan wheel 326 to rotate inside the cylindrical shell 323. The central part of the cylindrical shell 323 is an annular cavity. Coolant stored in the coolant tank 2 enters the cylindrical shell 323 through the bottom inlet pipe 322. The central part of the fan wheel 326 is flush with the central part of the cylindrical shell 323, with its edge located within the annular cavity. The fan wheel 326 rotates counterclockwise, in the same direction as the coolant entering the annular cavity of the cylindrical shell 323, thus cleaning the coolant. The coolant is accelerated and pushed into the annular cavity, discharged from the outlet of the cylindrical shell 323, and enters the ring pipe 321 through the output pipe 325. Under the continuous pushing action, the coolant is distributed to multiple sets of connecting pipes 313 and enters the corresponding double-fold pipe 312. Multiple sets of fins 314 on the outside of the double-fold pipe 312 are attached to the inner wall of the receiving frame 1. The heat of the workpiece is transferred to the fins 314 through the receiving frame 1, absorbed by the coolant with a lower temperature inside the double-fold pipe 312, and returned to the coolant tank 2 to restore the initial temperature and continue to participate in the circulation process. A certain amount of coolant is injected into the coolant tank 2 to maintain the cooling effect for a period of time. In this way, the heat of the workpiece is transferred, and the workpiece is prevented from overheating and deforming.
