Description

Technical Field

[0001] The invention belongs to the technical field of cleaning devices and relates to a rotary cleaning and fixing device. Background Art

[0002] Ultrasonic cleaning involves an ultrasonic generator emitting a high-frequency oscillation signal, which is converted by a transducer into high-frequency mechanical vibrations and propagated into the cleaning solvent. Ultrasonic waves radiate forward in the cleaning solvent in a sparse and dense pattern, causing the liquid to flow and generate tens of thousands of tiny bubbles with diameters of 50-500μm. These tiny bubbles in the liquid vibrate under the influence of the acoustic field, achieving a cleaning effect. This method offers the advantages of excellent cleaning effectiveness and simple operation. To achieve optimal cleaning results, the wash basket containing the workpieces needs to be rotated and tossed within the cleaning tank.

[0003] For example, a throwing and rotating device in a hydrocarbon cleaning machine has been designed and a Chinese patent application has been applied for, with application number: 201310516062.3 and publication number: CN103551331B. The throwing and rotating device in the hydrocarbon cleaning machine includes a throwing mechanism and a rotating mechanism provided on the cleaning tank of the hydrocarbon cleaning machine. The throwing mechanism includes a cylinder mounted on the side wall of the cleaning tank and a guide rod mechanism driven by the cylinder to drive the washing basket in the cleaning tank to move up and down. The rotating mechanism includes a roller provided under the washing basket, which is driven to rotate by a matching sprocket set and a chain. A driving mechanism for driving the rotating mechanism is provided on the inner wall of the cleaning tank. The driving mechanism includes a ratchet mechanism provided on the inner wall of the cleaning tank, the ratchet mechanism includes a ratchet, a pawl and a driven sprocket, wherein the driven sprocket is connected to the sprocket set by a chain, and the pawl is adjusted to cooperate with the ratchet by a gear mechanism. The gear mechanism includes a rack fixed vertically on the guide rod mechanism and a gear provided on the inner wall of the cleaning tank and meshing with the rack. Before the driving mechanism drives the washing basket to rotate, the washing basket and the driving mechanism need to be relatively fixed to prevent the washing basket from rolling freely in the washing tank.

[0004] The existing cleaning process involves first fixing the wash basket and the drive mechanism relative to each other and maintaining this fixed relationship without removing the wash basket. The workpiece to be cleaned is then placed into the wash basket. After the workpiece is completely cleaned, it is removed from the wash basket to allow other workpieces to be placed in the wash basket for cleaning. This method of placing and removing workpieces is time-consuming and labor-intensive, resulting in low workpiece cleaning efficiency. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose a rotary cleaning fixture to solve the problem of low efficiency in the rotary cleaning of existing workpieces.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] The cleaning basket of claim 1, wherein the cleaning basket is secured to the bottom of the support frame and is secured to the bottom of the support frame with a plurality of handles.

[0008] This rotary cleaning fixture is designed for use within a side-opening cleaning chamber. The front opening of the rotating frame is positioned opposite the opening of the cleaning chamber. The rotating frame is connected to a drive mechanism, enabling the drive mechanism to drive the rotating frame to rotate circumferentially about a horizontal axis. To clean workpieces, a large number of workpieces are loaded into a plurality of cleaning baskets. Conventional cleaning baskets can be used. A drive member drives rods 1 and 2 to move axially forward against the elastic force of an elastic member. Drives on the opposing ends of rods 1 and 2 drive two clamping jaws to swing upward to clear the opening. One of the cleaning baskets is then pushed horizontally into the rotating frame through the opening. The bottom of the rotating frame is supported by a support member. The drive member resets, and rods 1 and 2 move axially in opposite directions under the elastic force of the elastic member. Drives on both ends drive the two clamping jaws to swing downward toward each other, securing the basket from the front and rear sides. The cleaning chamber is then closed, and the rotating frame is driven to rotate circumferentially to ultrasonically clean the workpieces held in the cleaning basket within the rotating frame. After cleaning is completed, the driving member drives the first and second sub-rods to drive the two clamps to release the cleaning basket, and the cleaning basket can be taken out from the opening of the rotating frame to facilitate the next cleaning basket to be sent to the rotating frame and repeat the above steps for cleaning.

[0009] During use of the present rotary cleaning fixture, a driving member is used in conjunction with the first and second branch rods, an elastic member, and two clamping claws to quickly secure and release the cleaning basket, thereby greatly shortening the time interval between loading and unloading materials between two cleanings and improving cleaning efficiency. In addition, the front opening of the rotating frame allows the conveyor belt or assembly line for transporting the cleaning basket to be positioned lower than the opening, thereby reducing the height of the entire rotary cleaning fixture, making the present rotary cleaning fixture suitable for use in environments with insufficient height. The bottom of the rotating frame is used to support the support portion of the cleaning basket, which not only provides a foundation for horizontally transporting the cleaning basket, but also the support portion is configured to withstand the weight of the cleaning basket, reducing the driving force required for components such as the robot that transports the cleaning basket in or out of the rotating frame, thereby reducing the cost of automation.

[0010] In the above-mentioned rotating cleaning and fixing device, a long guide hole is provided on the top of the rotating frame, and the length direction of the guide hole is consistent with the front-to-back direction. The sides of the clamping jaws are penetrated by strip holes. The driving part is rod-shaped and vertically fixed to the sides of the branch rod one and the branch rod two. The driving part passes through the strip hole and the guide hole in turn. When the branch rod one and the branch rod two drive the driving part to move to the rear ends of the strip holes on the two clamping jaws respectively under the elastic force of the elastic member, the front end portion of the strip hole on the front clamping jaw is lower than the position of the guide hole and the front end portion of the strip hole on the rear clamping jaw is higher than the position of the guide hole. The guide holes arranged in front and behind the length are used to provide movement guides for the driving part inserted into the guide holes, ensuring the horizontal axial movement of the branch rod one, the branch rod two and the driving part. The strip holes opened on the clamping jaws, because the clamping jaws are hinged on the rotating frame, when the driving part moves forward and backward along the guide holes, it can act on the upper and lower side walls of the two strip holes to drive the two clamping jaws to swing downward or upward together, thereby realizing the control of the clamping jaw movement. The linkage structure is relatively simple and has strong stability.

[0011] In the aforementioned rotating cleaning fixture, the clamping jaws comprise two vertically arranged plate-shaped side panels and a reinforcement portion secured between the two side panels. The bottoms of the two side panels each have recessed tabs for snapping onto the cleaning basket. The clamping jaws comprise two spaced-apart side panels and a reinforcement portion secured between the two side panels, increasing their horizontal width. The two recessed tabs secure the cleaning basket, ensuring stable securement of the basket.

[0012] In the aforementioned rotating cleaning and securing device, a gap is provided between the opposing ends of the first and second sub-rods. Two elastic members are provided, one end of each acting on the first and second sub-rods, respectively, while the other end of each member abuts the rotating frame. The first and second sub-rods are separated by a small distance, and the two elastic members, supported by the rotating frame, each drive two clamping jaws to clamp the cleaning basket. This ensures that the clamping action of the two clamping jaws does not affect each other, ensuring the clamping degree of the clamps and the stability of the cleaning basket. Furthermore, the small distance between the first and second sub-rods does not affect the unlocking action of the driver driving the two, thus ensuring the stability and effectiveness of the unlocking.

[0013] In the aforementioned rotary cleaning fixture, the driving member is a pneumatic cylinder, the piston rod of which extends forward through the rotating frame. This linear drive of the cylinder piston rod directly propels the first and second branch rods axially, eliminating the need for other transmission mechanisms. This results in a simpler structure and more stable driving process.

[0014] In the aforementioned rotating cleaning and securing device, the support portion includes several rollers rotatably connected to the bottom of the rotating frame, with the rollers distributed along the front-to-back direction. The rollers facilitate horizontal insertion and removal of the cleaning basket, reducing wear and tear. Furthermore, the two clamping jaws can be used to properly adjust the front-to-back position of the cleaning basket when it is clamped, ensuring a more stable holding position.

[0015] In the aforementioned rotating cleaning fixture, the rotating frame has stoppers on both sides and the rear side for limiting the position of the cleaning basket. The stoppers on both sides and the rear side of the rotating frame can be used to assist in limiting the position, ensuring the accuracy of the position of the cleaning basket when entering the rotating frame, thereby ensuring the accuracy and stability of the clamping claws.

[0016] Compared with the existing technology, during the use of this rotary cleaning and fixing device, a driving member is used in conjunction with the first and second branch rods, an elastic member and two clamping claws to achieve rapid fixing and loosening of the cleaning basket, so that the time interval between loading and unloading between two cleanings is greatly shortened, thereby improving the cleaning efficiency.

DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figure 1 As shown, the rotating cleaning fixture includes a rotating frame 2 for accommodating a cleaning basket 1 therein, an opening 21 for the cleaning basket 1 to pass through is provided on the front side of the rotating frame 2, a supporting portion 22 for supporting the cleaning basket 1 is provided at the bottom of the rotating frame 2, and limiting portions 24 are provided on both sides and the rear side of the rotating frame 2 for limiting the cleaning basket 1. In this embodiment, the support part 22 is a roller, and there are several rollers, which are rotatably fixed to the bottom of the rotating frame 2 in two rows on the left and right sides. The axial direction of the roller is the left and right direction, that is, the roller can roll when the cleaning basket 1 is pushed in or taken out, so as to facilitate the entry and exit of the cleaning basket 1; the limiting part 24 includes a plate-shaped limiting plate, a limiting block and a back plate. There are two limiting plates and they are horizontally fixed on the opposite sides of the lower part of the rotating frame 2. The position of the limiting plate is higher than the position of the supporting part 22, and can be abutted against the side of the bottom of the cleaning basket 1 to limit the left and right positions of the cleaning basket 1. The back plate is located on the rear side of the rotating frame 2, and the limiting block is fixed on the front side of the back plate to abut against the rear side of the cleaning basket 1 to achieve limiting.

[0024] like Figure 2 and Figure 4As shown, the rotating cleaning fixture also includes two clamping jaws 3, a rod-shaped branch rod 1 41 and a branch rod 2 42, both of which are rod-shaped and coaxially arranged adjacent to each other, an elastic member 5, and a driving member 6 fixed to the rear of the rotating frame 2. The two clamping jaws 3 are arranged at the top of the rotating frame 2 and are respectively hinged to the front and rear of the rotating frame 2 through a horizontally arranged hinge shaft 7 located at the bottom of the clamping jaws 3. The branch rod 1 41 and the branch rod 2 42 are arranged on the top of the rotating frame 2 in the front-to-back direction, and the opposite ends of the branch rod 1 41 and the branch rod 2 42 each have a driving portion 43 that can act on the two clamping jaws 3 respectively. The branch rod 1 41 and the branch rod 2 42 can move axially under the elastic force of the elastic member 5 and drive the two clamping jaws 3 to swing downward toward each other. The driving member 6 can drive the branch rod 1 41 and the branch rod 2 42 to overcome the elastic force of the elastic member 5 and move and cause the two clamping jaws 3 to swing in opposite directions. In this embodiment, the driving portion 43 on the branch rod 1 41 and the branch rod 2 42 is located further forward than the corresponding hinge shaft 7, that is, the position of the driving portion 43 located at the front end side of the branch rod 1 41 and the branch rod 2 42 is further forward than the position of the hinge shaft 7 of the clamping jaw 3 located at the front, and the position of the driving portion 43 located at the rear end side of the branch rod 1 41 and the branch rod 2 42 is also further forward than the position of the hinge shaft 7 of the clamping jaw 3 located at the rear.

[0025] Specifically, both sides of the top front and rear of the rotating frame 2 have vertically erected vertical plates. Each of the four vertical plates has correspondingly long, strip-shaped guide holes 23 extending in the left-right direction, and the length direction of the four guide holes 23 is consistent with the front-to-back direction. The upper side portions of the two clamping jaws 3 each have a strip-shaped hole 31 extending through them. The drive unit 43 is in the shape of a round rod and is vertically fixed on both sides of the opposing ends of the first and second rods 41 and 42. Each drive unit 43 passes through the strip hole 31 and the guide hole 23 in sequence from the inside to the outside, and when the drive unit 43 moves back and forth along the guide hole 23, it can respectively rest against the two side walls of the strip hole 31. Preferably, the diameter of the drive unit 43 can be only slightly smaller than the width of the strip hole 31, so that the movement of the drive unit 43 can better drive the movement of the clamping jaws 3. The four drive units 43 are located on both sides of the opposing ends of the first and second rods 41 and 42. A limit nut 9 and a guide nut 8 are sleeved on the outside of the branch rod 1 41 and the branch rod 2 42. The two guide nuts 8 are fixed to the rotating frame 2. The branch rod 1 41 and the branch rod 2 42 respectively pass through a guide nut and can move freely axially relative to the guide nut 8. The two limit nuts 9 are threadedly connected to the branch rod 1 41 and the branch rod 2 42 respectively. The elastic member 5 is a spring, and there are two of them. The two springs are respectively sleeved on the outside of the branch rod 1 41 and the branch rod 2 42, and the two ends of each spring are respectively against the corresponding limit nut 9 and wire nut. The branch rod 1 41 and the branch rod 2 42 both move axially backward under the elastic force of the two springs. When the lever 41 is in the forward position and the lever 42 is in the forward position, the two levers 43 are in the forward position and the lever 42 is in the forward position.

[0026] like Figure 3As shown, the clamping jaw 3 includes two vertically arranged plate-shaped side panels 32 and a plate-shaped reinforcement portion 33 fixed between the two side panels 32. The two side panels 32 are each provided with a corresponding strip-shaped hole 31. The bottom of each side panel 32 has a recessed snap-on notch 34 for snapping onto the front and rear sides of the top of the cleaning basket 1. In this embodiment, the snap-on notch 34 on the bottom of the front clamping jaw 3 is located in front of the hinge axis 7 of the clamping jaw 3, while the snap-on notch 34 on the bottom of the rear clamping jaw 3 is located behind the hinge axis 7 of the clamping jaw 3, facilitating the clamping of the cleaning basket 1 from both sides.

[0027] This rotary cleaning fixture is installed and used within a cleaning chamber. The cleaning chamber includes a chamber body with a side opening and a chamber cover capable of opening and closing the opening. The rear side of the back plate of the rotating frame 2 is connected to an existing drive mechanism, such as a drive motor, which drives the entire rotating frame 2 in circumferential rotation. Of course, the drive motor is located outside the cleaning chamber and penetrates the cleaning chamber through an existing transmission structure, such as a gear rack, a screw nut, etc., to drive the rotating frame 2 in circumferential rotation.

[0028] When the workpiece is not cleaned, the first and second branch rods 41 and 42 drive the driving parts 43 at both ends to move to the rear ends of the strip holes 31 on the two clamping jaws 3 respectively under the elastic force of the elastic member 5. The front end portion of the strip hole 31 on the front clamping jaw 3 is lower than the position of the guide hole 23, and the front end portion of the strip hole 31 on the rear clamping jaw 3 is higher than the position of the guide hole 23.

[0029] When cleaning workpieces, a large number of workpieces can be loaded into several cleaning baskets 1. The piston rod of the driver 6 pushes forward, pushing the first and second rods 41 and 42 axially forward, overcoming the elastic force of the elastic member 5. Because the strip hole 31 in the front clamping jaw 3 is inclined and the front end of the strip hole 31 is lower than the guide hole 23, the first rod 41 pushes the front driver 43 forward and abuts against and acts on the upper side wall of the strip hole 31, thereby forcing the latch 34 at the bottom of the front clamping jaw 3 to swing upward about the hinge axis 7. At the same time, because the front end of the strip hole 31 in the rear clamping jaw 3 is higher than the guide hole 23, the second rod 42 pushes the rear driver 43 forward and abuts against and acts on the lower side wall of the strip hole 31 in the rear clamping jaw 3, forcing the latch 34 at the rear of the rear clamping jaw 3 to swing upward about the hinge axis 7, causing the two clamping jaws 3 to leave their clamping position and vacate their position. Then, the cleaning basket 1 is pushed horizontally into the rotating frame 2 through the warehouse opening and the opening 21 of the rotating frame 2 by a robot or other structure, and is slid and supported by the rollers at the bottom of the rotating frame 2 .

[0030] Then, the piston rod of the driving member 6 is reset, and the branch rod 1 41 and the branch rod 2 42 are moved backward in the opposite axial direction under the elastic force of the elastic member 5, and the two clamping jaws 3 are driven by the driving parts 43 at both ends to swing downward in the opposite directions, and the cleaning basket 1 is fastened from the front and rear sides to fix the cleaning basket 1.

[0031] Afterwards, the cleaning chamber is closed and the rotating frame 2 is driven to rotate circumferentially, performing rotary ultrasonic cleaning on the workpieces in the cleaning basket 1 fixed therein. After cleaning is complete, the driving member 6 drives the first and second rods 41 and 42 to cause the two clamping jaws 3 to release the cleaning basket 1. The cleaning basket 1 can then be removed from the opening 21 of the rotating frame 2, facilitating the transfer of the next cleaning basket 1 into the rotating frame 2 and the above steps to repeat.

[0032] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
