Description

Technical Field

[0001] This invention relates to the field of power battery technology, and more specifically, to an automatic cleaning device and method for workpieces. Background Technology

[0002] After being molded, metal structural components for power batteries often retain oil residue on their surface. This oil residue can easily cause poor welding during the welding process, affecting product quality; therefore, cleaning is necessary. Current cleaning methods typically involve placing the product in a designated carrier, then having a worker place the carrier onto a lifting mechanism. The lifting mechanism lowers the carrier into an ultrasonic cleaner for cleaning. After cleaning, the carrier is raised and removed for the next process. This existing lifting and cleaning method for metal structural components is inefficient. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide an automatic cleaning device and method for workpieces, which can improve the efficiency of automated production of workpieces.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] This invention provides an automatic cleaning device for workpieces, comprising:

[0006] A frame, wherein the front and rear ends of the frame are respectively the inlet and the outlet;

[0007] An ultrasonic cleaning mechanism is mounted on the frame and positioned near the feed inlet.

[0008] A drying mechanism is mounted on the frame and positioned near the discharge port.

[0009] A conveying mechanism is used to transport the workpiece from the inlet to the outlet, with the workpiece placed on the conveying mechanism and passing through the ultrasonic cleaning mechanism and the drying mechanism in sequence.

[0010] A pressing mechanism is provided on the side of the workpiece away from the conveying mechanism. There is a gap between the pressing mechanism and the conveying mechanism for the workpiece to pass through. The pressing mechanism is at least partially located within the ultrasonic cleaning mechanism. During the conveying process, the pressing mechanism limits the workpiece and cleans the surface of the workpiece.

[0011] The present invention also provides an automatic cleaning method for workpieces, comprising the following steps:

[0012] Place the workpiece on the conveyor mechanism;

[0013] The workpiece is conveyed by the conveying mechanism and then subjected to ultrasonic cleaning and drying in sequence.

[0014] During the ultrasonic cleaning and drying processes, a pressing mechanism is used to contact the upper surface of the workpiece, thereby limiting the position of the workpiece and cleaning its surface.

[0015] Implementing the embodiments of the present invention will have the following beneficial effects:

[0016] This invention discloses an automatic workpiece cleaning device and method. The automatic cleaning device includes a frame, an ultrasonic cleaning mechanism, a drying mechanism, a conveying mechanism, and a pressing mechanism. The front and rear ends of the frame are the inlet and outlet, respectively. The workpiece is placed on the conveying mechanism, which sequentially passes through the ultrasonic cleaning mechanism and the drying mechanism, transporting the workpiece from the inlet to the outlet. The pressing mechanism is located on the side of the workpiece away from the conveying mechanism, and is at least partially located within the ultrasonic cleaning mechanism.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Reference Figures 1-3 The automatic cleaning device for workpieces disclosed in this invention includes a frame 1, an ultrasonic cleaning mechanism 2, a drying mechanism 3, a conveying mechanism 4, and a pressing mechanism 5.

[0025] The front and rear ends of the frame 1 are the inlet and outlet, respectively. The ultrasonic cleaning mechanism 2 is set on the frame 1 and is located near the inlet. The drying mechanism 3 is set on the frame 1 and is located near the outlet.

[0026] The workpiece is placed on the conveying mechanism 4. The conveying mechanism 4 passes through the ultrasonic cleaning mechanism 2 and the drying mechanism 3 in sequence, driving the workpiece from the inlet to the outlet. The pressing mechanism 5 is set on the side of the workpiece away from the conveying mechanism 4. There is a gap between the pressing mechanism 5 and the conveying mechanism 4 for the workpiece to pass through. The pressing mechanism 5 is at least partially located inside the ultrasonic cleaning mechanism 2. During the conveying process, the pressing mechanism 5 limits the workpiece and cleans the surface of the workpiece.

[0027] It is understood that in this embodiment, the workpiece is placed on the conveying mechanism 4 at the feed port, and the conveying mechanism 4 moves to the discharge port to convey the workpiece. During the conveying process, the conveying mechanism 4 passes through the ultrasonic cleaning mechanism 2 and the drying mechanism 3 in sequence, so that the workpiece completes ultrasonic cleaning and drying during the conveying process, thereby realizing automated production.

[0028] In the ultrasonic cleaning mechanism 2, the workpiece passes through the gap between the conveying mechanism 4 and the pressing mechanism 5. The pressing mechanism 5 limits the workpiece to prevent it from shifting and leaving the conveying mechanism 4. While the workpiece is being ultrasonically cleaned, the pressing mechanism 5 cleans the surface of the workpiece. The pressing mechanism 5 and the ultrasonic cleaning mechanism 2 clean synchronously, which improves the cleaning efficiency.

[0029] In some alternative embodiments, refer to Figure 1 The conveying mechanism 4 includes a conveyor belt 41 and a drive wheel set. The conveyor belt 41 is sleeved on the drive wheel set, and the workpiece is placed on the conveyor belt 41. The drive wheel set drives the conveyor belt 41 to circulate from the feed port to the discharge port.

[0030] Specifically, the transmission wheel assembly includes a driving wheel 42 and a driven wheel 43. Driving wheels 42 or driven wheels 43 are provided at least at the feed inlet and discharge outlet. The driving wheels 42 and driven wheels 43 tension the conveyor belt 41. The conveying mechanism 4 also includes a drive motor 44. The driving wheel 42 is connected to the drive motor 44. The drive motor 44 drives the driving wheel 42 to rotate, and the rotation of the driving wheel 42 drives the conveyor belt 41 to move, causing the conveyor belt 41 to circulate from the feed inlet to the discharge outlet.

[0031] The workpiece is placed directly on the conveyor belt 41 for transport, eliminating the need for a cleaning basket and saving costs. At the same time, the pressing mechanism 5 can directly contact the workpiece to clean its surface, improving cleaning efficiency.

[0032] In some alternative embodiments, the pressing mechanism 5 includes a pressing component 51 and a supporting component 52 disposed opposite to each other, forming a channel for the conveyor belt 41 and the workpiece to pass through.

[0033] It should be noted that the conveyor belt 41 passes through the channel between the pressing component 51 and the supporting component 52. The supporting component 52 is positioned below the conveyor belt 41 to support it. The pressing component 51 is positioned above the conveyor belt 41 to limit the workpieces on the conveyor belt 41 while cleaning the workpiece surface. The pressing component 51 and the supporting component 52 limit the upper and lower movement of the conveyor belt 41 to ensure stable conveying.

[0034] Furthermore, the pressing assembly 51 includes multiple pressing roller brushes arranged sequentially from the feed inlet to the discharge outlet. Specifically, each pressing roller brush includes a roller core and a bristle layer surrounding the roller core. The roller core is rotatably connected to the frame 1. During workpiece conveying, the workpiece contacts the surface of the bristle layer, causing the pressing roller brush to rotate, and the bristle layer cleans the workpiece surface.

[0035] In other embodiments, the pressing assembly 51 may also be a cleaning sponge brush, which is fixed on the frame 1 to clean the surface of the workpiece.

[0036] Furthermore, the support assembly 52 includes a plurality of support rollers disposed below the conveyor belt 41, with the support rollers spaced apart from the inlet to the outlet, and used to support the conveyor belt 41. Preferably, the support rollers also include a brush layer surrounding them, so that the support assembly 52 can brush the lower surface of the workpiece while supporting the conveyor belt 41, thereby improving cleaning efficiency.

[0037] In other embodiments, the conveying mechanism 4 consists of multiple drive rollers (not shown in the figure), arranged closely from the feed inlet to the discharge outlet. The workpiece is placed on the drive rollers, and the drive rollers rotate to convey the workpiece. In this case, the pressing mechanism 5 consists of multiple pressing roller brushes, which are located on the side of the workpiece away from the drive rollers.

[0038] In some alternative embodiments, refer to Figure 1 The ultrasonic cleaning mechanism 2 includes a first housing 21 for holding cleaning fluid; the channel located inside the first housing 21 is below the surface of the cleaning fluid.

[0039] It should be noted that the supporting component 52 located in the first housing 21 is below the surface of the cleaning fluid, and the pressing component 51 located in the first housing 21 is at least below the surface of the cleaning fluid, so that the channel located in the first housing 21 is below the surface of the cleaning fluid, ensuring that the conveyor belt 41 and the workpiece it conveys are immersed in the cleaning fluid. Under the action of ultrasonic cavitation, the pressing mechanism 5 cleans the oil stains and residual particles on the surface of the workpiece.

[0040] Preferably, the conveyor belt 41 enters the first housing 44 below the surface of the cleaning fluid from the upper edge of the first housing 21, and exits the first housing 21 from the upper edge of the first housing 11. That is, after the conveyor belt 41 carries the workpiece into the first housing 21 from the upper edge, the conveyor belt 41 descends to below the surface of the cleaning fluid. During its transport within the first housing 21, the workpiece is immersed in the cleaning fluid for cleaning. When leaving the first housing 21, the conveyor belt 41 ascends and exits the first housing 21 from the upper edge. When there are two or more first housings 21, the transport path of the conveyor belt 41 is wavy. Since the conveyor belt 41 enters or exits the first housing 21 from the upper edge, the first housing 21 does not need to have openings in its side walls for the conveyor belt 41 to pass through, thus minimizing the risk of cleaning fluid overflow.

[0041] Furthermore, the ultrasonic cleaning mechanism 2 also includes a circulating pump 22, a filter 23, and a storage tank 24. An ultrasonic transducer 25 is installed inside the first housing 21. The conveying mechanism 4 passes through the first housing 21 to allow the workpiece to undergo ultrasonic cleaning within the first housing 21. The cleaning solution, after cleaning, is filtered by the filter 23 and enters the storage tank 24. The circulating pump 22 draws the filtered cleaning solution and delivers it back to the first housing 21, allowing the cleaning solution to be recycled, saving resources and reducing costs. A cooling pipe 26 can also be installed inside the storage tank 24 to regulate the temperature of the cleaning solution. Specifically, the cleaning solution can be a hydrocarbon cleaning solution.

[0042] In some optional embodiments, the drying mechanism 3 includes a second housing 35 and a drying air knife. The drying air knife is disposed within the second housing 35, which also contains a pressing mechanism 5. The drying air knife is disposed on the side of the pressing mechanism 5 opposite to the workpiece. During drying, the pressing mechanism 5 limits the workpiece to prevent it from shifting position and cleans the workpiece surface, thereby improving drying efficiency.

[0043] Preferably, the pressing mechanism 5 extends from the feed port to the discharge port to ensure stable conveying of the workpiece from the feed port to the discharge port.

[0044] Furthermore, the drying mechanism 3 also includes a drying fan, which is connected to the drying air knife. It should be noted that the drying air knife includes a water-cutting air knife 31 and / or a drying air knife 32. Preferably, the drying air knife includes a water-cutting air knife 31 and a drying air knife 32 arranged sequentially. The water-cutting air knife 31 is connected to a water-cutting fan 33, which supplies air to the water-cutting air knife 31 to peel off the surface liquid film. The drying air knife 32 is connected to a drying fan 34, which supplies air to the drying air knife 34 to dry the workpiece. The angles of the water-cutting air knife 31 and the drying air knife 32 are adjustable. Multiple drying methods are used to dry the workpiece, adapting to different drying needs, ensuring thorough drying of the workpiece, and facilitating subsequent processing and storage. In other embodiments, the drying mechanism 3 can also be an oven.

[0045] Furthermore, a third housing 11 is provided on the frame 1, and there is a gap between the third housing 11 and the second housing 35. The drying fan is disposed inside the third housing 11.

[0046] It should be noted that the first box 21, the second box 35, and the third box 11 can all be equipped with covers. The cover of the first box 21 closes the first box 21 to prevent the cleaning fluid from splashing. The cover of the second box 35 closes the second box 35 to prevent the cleaning fluid from splashing and to prevent the liquid from splashing onto the surface of the workpiece during drying. The cover of the third box 11 closes the third box 11, creating a gap between the third box 11 and the second box 35, which has an explosion-proof function.

[0047] Furthermore, the automatic cleaning device for the workpiece also includes a liquid-blocking air knife 6 and a liquid-blocking fan 7 connected to each other. The liquid-blocking air knife 6 is located on the side of the first housing 21 near the discharge port, and the liquid-blocking fan 7 is also located in the third housing 11.

[0048] Understandably, the liquid-blocking air knife 6 is supplied with air by the liquid-blocking fan 7 to blow away most of the liquid on the surface of the workpiece, reducing the amount of liquid brought into the drying zone. The angle of the liquid-blocking air knife 6 is adjustable; for example, the liquid-blocking air knife 6 can be tilted at 30° to point at the surface of the workpiece and blow the liquid on the surface of the workpiece into the first chamber 21.

[0049] Furthermore, the number of first chambers 21 is two or more. A liquid-blocking air knife 6 can be installed after each first chamber 21 to blow away residual waste liquid on the workpiece surface. The figure shows an example with three first chambers 21, which improves the cleaning effect on the workpiece.

[0050] In some optional embodiments, the second housing 35 includes a gas outlet (not shown in the figure), and the first housing 21 includes a gas inlet (not shown in the figure). The gas outlet and the gas inlet are connected by a pipeline. During the drying process, the liquid on the surface of the workpiece is converted into gas and returns to the first housing 21 through the gas outlet and the gas inlet. The cleaning liquid is recycled, which protects the environment and saves costs.

[0051] Furthermore, the second chamber 35 also includes a protective gas inlet. Before the workpiece enters the second chamber 35, protective gas is introduced into the second chamber 35 to prevent the workpiece from oxidizing during the drying process.

[0052] The automatic cleaning method for workpieces disclosed in this invention includes the following steps:

[0053] (1) Place the workpiece on the conveying mechanism 4.

[0054] (2) The workpiece is conveyed by the conveying mechanism 4 and then subjected to ultrasonic cleaning and drying in sequence. During the ultrasonic cleaning and drying process, the pressing mechanism 5 also contacts the upper surface of the workpiece, which limits the workpiece and cleans the surface of the workpiece.

[0055] Understandably, the workpiece undergoes ultrasonic cleaning and drying during the conveying process, enabling automated production. During the ultrasonic cleaning and drying process, the pressing mechanism 5 limits the workpiece and cleans its surface, improving cleaning efficiency.

[0056] Furthermore, the conveying mechanism 4 conveys the workpiece through the ultrasonic cleaning mechanism 2 and the drying mechanism 3 in sequence for ultrasonic cleaning and closed drying, respectively. The gas generated during the drying process is circulated back to the ultrasonic cleaning mechanism 2.

[0057] Optionally, the cleaning fluid includes hydrocarbon cleaning fluid. Hydrocarbon cleaning fluid has a strong dissolving ability for oil stains, and it is easy to evaporate after cleaning, leaving little residue. After cleaning with hydrocarbon cleaning fluid, the workpiece can be dried directly without rinsing. The hydrocarbon cleaning fluid gas generated during drying can be recycled to the ultrasonic cleaning unit 2 for reuse, reducing solvent consumption costs and waste liquid treatment costs.

[0058] Furthermore, the drying process is a closed drying process. Before the workpiece enters the drying mechanism 3, a protective gas, such as an inert gas, is introduced into the drying mechanism 3 to drive out the air before heating and drying, thus preventing the workpiece from coming into contact with oxygen and oxidizing during the heating and drying process.

[0059] Furthermore, the workpiece is conveyed by the conveying mechanism 4 for ultrasonic cleaning, including:

[0060] After the conveying mechanism 4 enters the ultrasonic cleaning mechanism 2 from the upper edge, the conveying mechanism 4 drives the workpiece to descend until it is below the surface of the cleaning fluid in the ultrasonic cleaning mechanism 2.

[0061] The workpiece is conveyed forward by the conveying mechanism 4 and ultrasonically cleaned below the surface of the cleaning fluid;

[0062] The conveying mechanism 4 drives the workpiece to rise until it leaves the ultrasonic cleaning mechanism 2 from the upper edge of the ultrasonic cleaning mechanism 2.

[0063] It can be understood that when there are two or more ultrasonic cleaning mechanisms 2, the transmission path of the transmission mechanism 4 is wavy. The transmission mechanism 4 enters or exits the ultrasonic cleaning mechanism 2 through the upper edge of the ultrasonic cleaning mechanism 2. The ultrasonic cleaning mechanism 2 does not need to have an opening in its side wall for the transmission mechanism 4 to pass through, which makes it less likely to cause the cleaning fluid to overflow.

[0064] In this embodiment, the ultrasonic cleaning mechanism 2, drying mechanism 3, conveying mechanism 4, and pressing mechanism 5 can be the ultrasonic cleaning mechanism 2, drying mechanism 3, conveying mechanism 4, and pressing mechanism 5 described in any of the above embodiments of the automatic cleaning device, and will not be repeated here.

[0065] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
