Description

Technical Field

[0001] This invention belongs to the field of cleaning device technology, and relates to a cleaning chamber for ultrasonic cleaning. Background Technology

[0002] Ultrasonic cleaning involves an ultrasonic generator emitting a high-frequency oscillation signal, which is converted into a high-frequency mechanical oscillation by a transducer and propagated into the cleaning solvent. The ultrasonic waves radiate forward in the cleaning solvent in alternating dense and sparse patterns, causing the liquid to flow and generating tens of thousands of tiny bubbles with a diameter of 50-500 μm. These tiny bubbles in the liquid vibrate under the action of the acoustic field, thus achieving a cleaning effect. It has the advantages of good cleaning effect and simple operation.

[0003] For example, a fully automatic ultrasonic cleaning and drying machine has been designed and a Chinese patent has been applied for, with application number 202020938957.1 and publication number CN212821424U. This fully automatic ultrasonic cleaning and drying machine includes an ultrasonic cleaning and drying chamber, a cleaning liquid recovery tank, and a control panel. The cleaning and drying chamber has a drain basket inside, with a liquid level sensor located on the top of the drain basket on the side wall of the chamber. A high-pressure gas nozzle is located on the top of the drain basket, connected via a gas guide pipe to an air pump located below the cleaning and drying chamber. Several ultrasonic transmitters are located above the air pump at the bottom of the cleaning and drying chamber. A heating wire is located on the inner wall of the cleaning and drying chamber, and a temperature sensor is located at the bottom of the chamber. The cleaning liquid recovery tank is connected to a water pump via a water guide pipe, extending into the cleaning and drying chamber. A filter cotton is located on one side of the water guide pipe inside the cleaning liquid recovery tank, with a drain outlet on the top of the filter cotton located at the bottom of the cleaning and drying chamber. In order to prevent the cleaning fluid from leaking out of the chamber, the ultrasonic cleaning and drying chamber of this fully automatic ultrasonic cleaning and drying machine has its opening facing upwards, and is sealed and opened by a top cover.

[0004] To ensure a tight seal when the top cover is on top of the drying chamber, a ring-shaped sealing ring is often installed around the opening. The top cover is then moved axially towards the sealing ring until it presses against the top end face of the sealing ring to achieve a seal. This is achieved by moving the top cover downwards to press it firmly against the top of the drying chamber. However, when the drain basket is fed into and removed from the drying chamber, the conveying direction is also up and down; that is, the direction of opening and closing the drying chamber opening is the same as the feeding direction. This easily causes interference between the top rod, the drain basket, and the feeding device. To address this, the conventional technique used by those skilled in the art is to increase the lifting height of the top cover to provide sufficient space for the conveying of the drain basket. However, this method not only significantly increases the required height of the entire equipment, reducing its applicability, but also increases the time required to open and close the top cover, reducing cleaning efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a cleaning chamber for ultrasonic cleaning, which solves the problem of how existing cleaning chambers for ultrasonic cleaning can reduce the environmental space requirements for use while ensuring airtightness.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A cleaning chamber for ultrasonic cleaning includes a chamber cover and a chamber body with a chamber opening. An annular sealing ring is fixed to the chamber body around the chamber opening. The chamber opening is located on the side of the chamber body. The cleaning chamber also includes two guide rails, a guide frame, and a driving component. The two guide rails are vertically fixed to the chamber body and are respectively located on both sides of the chamber opening. The guide frame extends into the two guide rails on both sides and can move up and down along the guide rails under the drive of the driving component. The chamber cover is vertically disposed between the guide frame and the chamber opening. Between the guide frame and the bin cover, several rod-shaped hinges are provided. One end of each hinge is hinged to the guide frame, and the other end of each hinge is hinged to the bin cover. The position of the hinged end that is hinged to the guide frame is higher than the position of the other end, allowing the bin cover to swing relative to the guide frame towards the bin opening. The side of the bin body below the bin opening has a protruding limiting part. When the bin cover moves down with the guide frame, it can abut against the limiting part, and when the drive component drives the guide frame to continue moving down, the bin cover can move towards the bin opening and press tightly against the aforementioned sealing ring.

[0008] When the cleaning chamber for ultrasonic cleaning is opened, the drive unit moves the guide frame upward along the guide rail. The chamber cover, under its own weight, naturally droops and is connected to the guide frame through several hinges. The guide frame then uses these hinges to smoothly move the chamber cover upward, separating it from the chamber opening, allowing the workpiece basket to be pushed in or removed horizontally. When closing, the drive unit moves the guide frame downward along the guide rail. The chamber cover, under its own weight, moves downward synchronously with the guide frame until the lower side of the cover abuts against the upper side of the limiting part. At this point, the drive unit continues to move the guide frame downward along the guide rail. Because the lower side of the chamber cover is blocked from moving further, the chamber cover and the guide frame will swing relative to each other around the hinge points at both ends of the hinges. Due to the limiting effect of the guide rail on both sides of the guide frame, horizontal displacement cannot occur. Therefore, the chamber cover moves away from the guide frame around the hinge points and closer to the chamber opening until the chamber cover moves horizontally and presses tightly against the sealing ring, achieving a seal on the chamber opening.

[0009] In this ultrasonic cleaning chamber, the use of hinges, limiting parts, and guide rails allows a single linear drive unit to both move the chamber lid up and down and press it horizontally, resulting in a simple structure that ensures a tight seal. When the chamber lid opens, it moves upward with the guide frame, allowing the workpiece basket to be horizontally fed into the chamber opening. This means the opening direction of the lid and the feeding direction of the workpiece basket are perpendicular and not in the same direction, minimizing interference. This eliminates the need for the lid to move a large distance to make way when opening, reducing the space requirements and making the ultrasonic cleaning chamber more convenient to arrange and applicable to a wider range of situations. Therefore, the above-described structure of this ultrasonic cleaning chamber ensures a tight seal while reducing the space requirements.

[0010] In the aforementioned cleaning chamber for ultrasonic cleaning, the limiting part includes a limiting seat fixed to the side of the chamber body, a rod-shaped rotating shaft, and a block-shaped limiting block. The limiting block is rotatably connected to the limiting seat via the rotating shaft horizontally passing through it, and the top of the limiting block is higher than the top of the limiting seat. This higher-positioned, rotatable limiting block can better support and limit the movement of the chamber cover as it moves downwards and towards the chamber opening, ensuring the stability of the seal between the chamber cover and the outer sealing ring of the chamber opening.

[0011] In the aforementioned cleaning chamber for ultrasonic cleaning, the limiting block is fixed to the rotating shaft, which is rotatably mounted on the limiting seat. The limiting seat has a locking hole, and a locking element is threaded into the locking hole. When the locking element is screwed in along the thread, it presses tightly against the outer surface of the rotating shaft. After the limiting block rotates relative to the limiting seat, the rotating shaft can be locked by screwing in the locking element, thereby locking the position of the limiting block. For example, the top surface of the limiting block can be locked at an angle where the side closer to the chamber opening is lower and the other side is higher, allowing the limiting block to better guide the movement of the chamber cover towards the chamber opening.

[0012] In another scenario, in the aforementioned cleaning chamber for ultrasonic cleaning, the limiting part and the chamber body are separate structures, and the limiting part is detachably connected to the side of the chamber body. The detachable limiting part can be adjusted according to actual usage, without changing the stroke of the drive component, by changing the size and specifications of the limiting block to change the position limiting the lower side of the chamber cover, thereby changing the tightness between the chamber cover and the sealing ring. This ensures a good seal even after long-term use.

[0013] In the aforementioned cleaning chamber for ultrasonic cleaning, the guide frame includes a frame, several sliding rollers rotatably connected to both sides of the frame, and several limiting rollers rotatably connected to both sides of the frame. The outer surfaces of the sliding rollers abut against the bottom surface of the guide rail, and the outer surfaces of the limiting rollers abut against the side walls of the guide rail. The sliding rollers allow for rolling friction between the guide frame and the guide rail as the guide frame moves up and down, ensuring smooth lifting and lowering of the guide frame. The limiting rollers abut against the side walls of the guide rail to limit the horizontal position of the guide frame, preventing horizontal swaying and thus ensuring the stability and sealing effect of the chamber cover relative to the guide frame and its contact with the sealing ring.

[0014] In the aforementioned cleaning chamber for ultrasonic cleaning, several hinge seats 1 are fixed on the guide frame, and several hinge seats 2 are correspondingly fixed on the chamber cover. The number of hinge seats 1, hinge seats 2, and hinge components is the same. Each hinge component has both ends hinged to the corresponding hinge seat 1 and hinge seat 2, respectively. The several hinge seats 1 are arranged in a square pattern. The several hinge seats are arranged in a square pattern on one side, i.e., at four corners. This arrangement of hinge seats 1 and their corresponding hinge seats 2 provides a more stable connection and support for the chamber cover, preventing the vertically positioned chamber cover from swinging freely, thus ensuring stability during sealing.

[0015] Compared with existing technologies, the cleaning chamber used for ultrasonic cleaning has the following advantages:

[0016] 1. By utilizing the combination of hinges, limiting parts, guide rails and other structures, the linear drive of a single drive component can both push the lid up and down and press the lid horizontally, reducing the number of drive components, resulting in a simple structure and good sealing effect.

[0017] 2. When the chamber cover is opened, it moves upward with the guide frame, and the workpiece basket can be horizontally fed into the side-opening chamber opening. That is, the opening direction of the chamber cover and the feeding direction of the workpiece basket are perpendicular to each other and not in the same direction, so interference is not likely to occur. There is no need for the chamber cover to move a greater distance to make way when opening, which reduces the requirements for environmental space and makes the layout of the cleaning chamber originally used for ultrasonic cleaning more convenient and has a wider range of applications.

Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] Example 1

[0025] like Figure 1 As shown, the cleaning chamber for ultrasonic cleaning includes a plate-shaped chamber cover 1 and a chamber body 2 with a circular opening 21 on the side. The side of the chamber body 2 with the opening 21 is flat, and a recessed annular sealing groove is provided around the opening 21 on this side of the chamber body 2. An annular sealing ring 3 is fixed in the sealing groove, and the sealing ring 3 partially extends out of the sealing groove. The sealing ring 3 can be made of an elastic material such as rubber.

[0026] The cleaning chamber for ultrasonic cleaning also includes two straight guide rails 4, a vertically arranged flat guide frame 5, and a drive unit 6 positioned above the guide frame 5. Both guide rails 4 are vertically fixed to one side of the chamber body 2 with an opening 21, and the two guide rails 4 are located on opposite sides of the opening 21. The two sides of the guide frame 5 extend into the two guide rails 4 and can move up and down along the guide rails 4 under the drive of the drive unit 6. The bin cover 1 is vertically positioned between the guide frame 5 and the bin opening 21. Several hinge seats 51 are fixed on the guide frame 5, and several hinge seats 11 are correspondingly fixed on the bin cover 1. Rod-shaped hinge members 7 are provided between each of the hinge seats 51 and 11, with each hinge member 7 hinged at both ends to the corresponding hinge seat 51 and 11 via a horizontally positioned hinge shaft 9. Each hinge member 7 is inclined relative to the vertical direction, and the position of one end hinged to the hinge seat 51 is higher than the other end. The bin body 2 below the bin opening 21 has a protruding limiting part 8 on its side, which abuts against the upper side of the limiting part 8 when the bin cover 1 moves downward with the guide frame 5. In this embodiment, the two guide rails 4 are recessed on opposite sides to form a track, so that the cross-section of the guide rail 4 is U-shaped; the guide frame 5 includes a square frame 52; the driving component 6 is a cylinder, the cylinder body is fixed to the chamber 2 or other components or brackets other than the cleaning chamber used for ultrasonic cleaning, the piston rod of the cylinder faces downward and the lower end of the piston rod is hinged to the guide frame 5; there are four hinge seats 1 51 and four hinge seats 2 11, which are distributed at the four corners of a square.

[0027] like Figure 2 As shown, both hinge seat 1 51 and hinge seat 2 11 consist of two vertically arranged plate-shaped side plates with a gap between them to allow the hinge member 7 to extend into. Hinge seat 1 51 is fixed to the side of the cover 1 facing the guide frame 5, and hinge seat 2 11 is fixed to the lower side of the upper and lower parts of the frame 52, with the position of hinge seat 2 11 slightly lower than that of hinge seat 1 51. The two ends of the hinge member 7 extend into hinge seat 1 51 and hinge seat 2 11 respectively and are hinged to hinge seat 1 51 and hinge seat 2 11 respectively through horizontally arranged hinge shafts 9.

[0028] like Figure 3 As shown, the limiting part 8 includes a U-shaped limiting seat 81 fixed to the side of the compartment 2, a cylindrical rotating shaft 82, and a square-shaped limiting block 83. The limiting block 83 is rotatably connected to the limiting seat 81 via the rotating shaft 82, which is horizontally inserted through the limiting seat 81. The top surface of the limiting block 83 is flat. In this embodiment, the limiting block 83 is fixed to the rotating shaft 82, and the rotating shaft 82 is rotatably inserted through the limiting seat 81. The limiting seat 81 has a locking hole 84, and a locking member is threaded into the locking hole 84 of the limiting seat 81. When the locking member is screwed in along the thread, it can press tightly against the outer surface of the rotating shaft 82. Here, the locking member can be a screw.

[0029] like Figure 4 As shown, the guide frame 5 also includes several sliding rollers 53 rotatably connected to both sides of the frame 52 and several limiting rollers 54 rotatably connected to both sides of the frame 52. Both the sliding rollers 53 and the limiting rollers 54 are vertically arranged. There are at least four sliding rollers 53, with at least two sliding rollers 53 connected to each side of the frame 52. The two sliding rollers 53 on each side are distributed at the upper and lower parts of the frame 52. The axial direction of each sliding roller 53 is aligned with the orientation of the opening 21, and the outer surfaces of the sliding rollers 53 on both sides of the frame 52 can abut against the bottom surfaces of the two guide rails 4 respectively. The axial direction of the limiting rollers 54 is perpendicular to the axial direction of the sliding rollers 53, allowing the outer surfaces of the limiting rollers 54 to abut against the opposite side walls of the guide rails 4. To more clearly describe the orientation of the sliding roller 53 and the limiting roller 54, taking the opening 21 on the front side of the compartment 2 as an example, the guide rails 4 are respectively set on the left and right sides of the opening 21. The axis of the sliding roller 53 is the front-back direction, while the axis of the limiting roller 54 is the left and right sides.

[0030] When the cleaning chamber used for ultrasonic cleaning is opened, the piston rod of the drive unit 6 retracts, the drive guide frame 5 moves upward along the guide rail 4, and the chamber cover 1 is smoothly moved upward by several hinges 7. The chamber cover 1 leaves the chamber opening 21, and the chamber opening 21 is opened, allowing the workpiece basket to be pushed in or taken out horizontally.

[0031] When the cleaning chamber used for ultrasonic cleaning needs to be closed, the piston rod of the drive unit 6 extends, driving the guide frame 5 to move downward along the guide rail 4. Under the action of gravity, the chamber cover 1 moves downward synchronously with the guide frame 5 until the lower side of the chamber cover 1 abuts against the upper side of the limiting block 83. At this time, the drive unit 6 drives the guide frame 5 to continue moving downward along the guide rail 4. Because the lower side of the chamber cover 1 is blocked by the top surface of the limiting block 83 and cannot move downward, and there are no other limiting structures set on the front and rear sides of the chamber cover 1 except for the guide frame 5 and the chamber body 2, the chamber cover 1 and the guide frame 5 will swing back and forth relative to each other around the hinge seat 1 51 and the hinge seat 2 11. Because the front and rear sides of the guide frame 5 are limited by the guide rail 4 through the limiting roller 54, they cannot make horizontal displacement. Therefore, the chamber cover 1 moves away from the guide frame 5 around the hinge point and moves backward towards the chamber opening 21 until the chamber cover 1 is pressed tightly against the sealing ring 3, thus sealing the chamber opening 21. Here, as needed, the locking device can be loosened, and the rotating shaft 82 and the limiting block 83 can be rotated so that the top surface of the limiting block 83 is tilted towards the opening 21, so as to better guide the cover 1 closer to the opening 21.

[0032] Example 2

[0033] The technical solution of this embodiment is largely the same as that of Embodiment 1, except that the limiting part 8 and the chamber 2 are separate structures, and the limiting part 8 is detachably connected to the side of the chamber 2.

[0034] Here, the limiting part 8 can be square-shaped, and it can be detachably connected to the chamber body 2 by a screw that passes horizontally through the limiting part 8 and is threadedly connected to the chamber body 2.

[0035] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
