Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece processing equipment technology, and in particular to a cleaning device. Background Technology
[0002] In the production process of workpieces, to improve their corrosion resistance and aesthetics, surface coating is usually required. For example, a sprocket may be a workpiece surface coated with a powder coating. However, before coating, the workpiece surface often contains impurities such as oil and dust. If not thoroughly cleaned, these impurities will affect the coating quality, leading to reduced coating adhesion, bubbles, and peeling. In related technologies, workpiece cleaning methods mostly rely on manual cleaning or simple cleaning equipment. Manual cleaning is inefficient, labor-intensive, and inconsistent in its results; while simple cleaning equipment often fails to clean thoroughly, unable to meet the requirements of high-quality coating. Therefore, an automated cleaning device capable of efficiently and thoroughly cleaning workpiece surfaces is needed. Utility Model Content
[0003] This invention provides a cleaning device, the purpose of which is to improve the cleaning effect of workpieces.
[0004] To achieve the above objectives, this utility model provides a cleaning device for cleaning workpieces, the cleaning device comprising:
[0005] The cleaning tank is configured to contain cleaning fluid;
[0006] The clamping assembly includes a rotating shaft, clamping plates, and a limiting member. The rotating shaft is rotatably connected to the cleaning tank. The clamping plates are configured in pairs, forming a placement groove to accommodate the workpiece. The arrangement direction of the two clamping plates in the pair is a first direction. The rotating shaft passes through the clamping plates along the first direction. The clamping plates are able to remain relatively stationary with respect to the rotating shaft. The limiting member is connected to the clamping plates and protrudes along the first direction from the side of the clamping plates near the placement groove. The limiting member can abut against the workpiece so that the workpiece can remain relatively stationary with respect to the limiting member.
[0007] A cleaning assembly includes a cleaning brush rotatably connected within the cleaning tank, the cleaning brush being configured to clean the workpiece.
[0008] In one embodiment, the clamping piece has a limiting groove, the opening of the limiting groove facing the placement groove, and the limiting member is slidably connected to the placement groove.
[0009] In one embodiment, the clamping assembly further includes an elastic element, one end of which is connected to the bottom wall of the limiting groove along the first direction, and the other end of which is connected to the limiting element, so that the limiting element can move relative to the clamping piece along the first direction.
[0010] In one embodiment, the limiting member includes a limiting block and a clamping plate connected to each other, wherein the limiting block is disposed between the clamping piece and the clamping plate along the first direction.
[0011] In one embodiment, the radial dimension of the clamping piece is smaller than the radial dimension of the workpiece.
[0012] In one embodiment, the bristles of the cleaning brush can be located within the gap between the clamping plate and the corresponding workpiece.
[0013] In one embodiment, the cleaning assembly includes a water pump and spray pipes that are interconnected, the water pump being configured to increase the water pressure in the spray pipes, the spray pipes being spaced apart within the cleaning tank along the first direction.
[0014] In one embodiment, the cleaning apparatus includes a heating component configured to increase the temperature of the cleaning fluid.
[0015] The above-mentioned solution of this utility model has the following beneficial effects:
[0016] In this embodiment, the workpiece is positioned between a pair of clamping plates, and a limiting member protruding from the clamping plates abuts against the surfaces of the workpiece on opposite sides along the first direction. This clamps the workpiece, allowing it to rotate synchronously with the rotating shaft when it rotates. This ensures the workpiece is thoroughly immersed in the cleaning fluid and prevents it from slipping or moving along the first direction under the scrubbing action of the cleaning brush, thus improving the cleaning effect of the cleaning device. Furthermore, the limiting member protrudes from the clamping plate towards the placement groove along the first direction and abuts against the workpiece, creating a preset distance between the clamping plate and the corresponding workpiece. This preset distance allows the brush bristles of the cleaning brush to pass through. The limiting member is smaller than the clamping plate, reducing the area where the workpiece is clamped and increasing the area of the workpiece surface that can be cleaned by the cleaning brush. This allows the cleaning device of this application to maximize the cleanable area of the workpiece while limiting its position, reducing the possibility of oil and dust on the workpiece surface and improving the cleaning effect.
[0017] Other beneficial effects of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0026] This application provides a cleaning device for cleaning a workpiece 5, for example, the workpiece 5 can be an annular sprocket. Specifically, please refer to... Figure 1 and Figure 2 The cleaning device includes a cleaning tank 1, a clamping assembly 2, and a cleaning assembly 3. The cleaning tank 1 is configured to contain a cleaning solution containing components that remove oil stains from the surface of the workpiece 5, thereby improving the cleaning effect on the workpiece 5. The cleaning tank 1 can be made of a material with a certain strength and hardness, such as stainless steel. The cleaning tank 1 can be a box with an opening to allow the clamping assembly 2, the cleaning assembly 3, and the workpiece 5 to enter the cleaning tank 1 through the opening. For example, please refer to... Figure 2 The cleaning device may include multiple support legs 7, which are positioned below the cleaning tank 1 to support it. The clamping assembly 2 includes a rotating shaft 21, a clamping plate 22, and a limiting member 23. The rotating shaft 21, clamping plate 22, and limiting member 23 are all made of materials with sufficient strength and hardness, such as stainless steel. The rotating shaft 21 is rotatably connected inside the cleaning tank 1. For example, the rotating shaft 21 may extend along the length of the cleaning tank 1 from one end to the other. (See also...) Figure 3 The clamping pieces 22 are configured in pairs, and the paired clamping pieces 22 surround a placement groove 221 to accommodate the workpiece 5. The arrangement direction of the two paired clamping pieces 22 is a first direction. For example, Figure 1 and Figure 2 The direction indicated by R1 is the first direction. The rotating shaft 21 passes through the clamping piece 22 along the first direction, so that the placement groove 221 surrounds the outer circumference of the rotating shaft 21. The clamping piece 22 can remain relatively stationary with respect to the rotating shaft 21. For example, the clamping piece 22 can be as follows: Figure 3The workpiece 5 is configured in a circular shape. The limiting member 23 is connected to the clamping piece 22, allowing the limiting member 23 to remain relatively stationary with respect to the clamping piece 22. The limiting member 23 protrudes along a first direction from the side of the clamping piece 22 closest to the placement groove 221, and can abut against the workpiece 5, allowing the clamping piece 22 to maintain a preset distance from the workpiece 5 in the first direction, and also allowing the workpiece 5 to remain relatively stationary with respect to the limiting member 23. The cleaning assembly 3 includes a cleaning brush 31, which is rotatably connected to the cleaning tank 1 and is configured to clean the workpiece 5. For example, please refer to... Figure 1 and Figure 2 The cleaning brush 31 can extend from one end of the cleaning box 1 to the other end along the first direction. There are two cleaning brushes 31, and the two cleaning brushes 31 are arranged at intervals along the direction intersecting the first direction so that the workpiece 5 can be brushed by the cleaning brushes 31 on both sides of the radial direction, so as to improve the cleaning effect of the workpiece 5.
[0027] For example, the clamping assembly 2 further includes a fixing member configured to fix the relative position between the clamping piece 22 and the rotating shaft 21, so that the clamping piece 22 can adjust its relative position with respect to the rotating shaft 21, so that the clamping piece 22 can adjust its position relative to the rotating shaft 21 according to the thickness of the workpiece 5, so that the workpiece 5 can be better clamped.
[0028] For example, please refer to Figure 1 A rotating shaft 21 passes through the workpiece 5 along a first direction. The workpiece 5 is positioned between two paired clamping plates 22 along the first direction. A limiting member 23 abuts against both sides of the workpiece 5 along the first direction, allowing the workpiece 5, clamping plates 22, limiting member 23, and rotating shaft 21 to remain relatively stationary. At least a portion of the workpiece 5 is immersed in the cleaning fluid. When the rotating shaft 21 rotates, it drives the workpiece 5 to rotate synchronously, ensuring that the cleaning fluid wets the workpiece 5 as much as possible. Please refer to [link to relevant documentation]. Figure 2 The cleaning brush 31 is positioned above the rotating shaft so that the bristles of the cleaning brush 31 do not directly contact the cleaning liquid contained in the cleaning tank 1. When the cleaning brush 31 rotates and the rotation direction of the cleaning brush 31 is opposite to the rotation direction of the rotating shaft 21, the cleaning brush 31 can thoroughly clean the surface of the workpiece 5.
[0029] For example, please refer to Figure 1 and Figure 2The cleaning device may further include a first drive member 41 and a second drive member 42. The first drive member 41 is configured to drive the rotating shaft 21 to rotate, and the first drive member 41 may be a motor. The second drive member 42 may include a drive motor, a driving gear, and a driven gear. There may be two cleaning brushes 31, one of which is connected to the output shaft of the drive motor to drive the cleaning brush 31 to rotate. The output shaft of the drive motor is also connected to the driving gear, which meshes with the driven gear. The other cleaning brush 31 is connected to the driven gear so that the two cleaning brushes 31 can rotate simultaneously.
[0030] For example, please refer to Figure 3 The number of limiting members 23 can be multiple, for example, two, with the two limiting members 23 spaced apart on the side of the clamping piece 22 near the placement groove 221.
[0031] In this embodiment, the workpiece 5 is disposed between a pair of clamping plates 22, and the limiting member 23 protruding from the clamping plate 22 abuts against the surfaces of the workpiece 5 on opposite sides along the first direction, so that the workpiece 5 can be clamped. As a result, when the rotating shaft 21 rotates, the workpiece 5 can rotate synchronously with the rotating shaft 21 by relying on the static friction between itself and the limiting member 23, so that the workpiece 5 can be wetted by the cleaning liquid as much as possible, and the workpiece 5 is less likely to slip and move along the first direction under the brushing of the cleaning brush 31, which is beneficial to improving the cleaning effect of the cleaning device on the workpiece 5. Furthermore, the limiting member 23 protrudes from the side of the clamping piece 22 facing the placement groove 221 along the first direction and abuts against the workpiece 5, so that the clamping piece 22 and the corresponding workpiece 5 are at a preset distance along the first direction. This preset distance allows the bristles of the cleaning brush 31 to pass through. The size of the limiting member 23 is smaller than that of the clamping piece 22, which reduces the area of the workpiece 5 being clamped, thereby increasing the area of the workpiece 5 surface that can be cleaned by the cleaning brush 31. This allows the cleaning device of this application to maximize the area of the workpiece 5 that can be cleaned while limiting the workpiece 5, thereby reducing the possibility of oil and dust on the surface of the workpiece 5 and improving the cleaning effect of the workpiece 5.
[0032] In one embodiment, please refer to Figure 3 The clamping piece 22 has a limiting groove 222, the opening of which faces the placement groove 221. The limiting member 23 is slidably connected to the placement groove 221 to improve the adjustment capability of the limiting member 23, so that the limiting member 23 can adjust its position relative to the clamping piece 22 according to different types of workpieces 5 to obtain a better clamping effect.
[0033] In one embodiment, please refer to Figure 3The clamping assembly 2 also includes an elastic element 24. The elastic element 24 can be a spring. One end of the elastic element 24 along the first direction is connected to the bottom wall of the limiting groove 222, and the other end of the elastic element 24 is connected to the limiting element 23, so that the limiting element 23 can move relative to the clamping piece 22 along the first direction. On the one hand, when the surfaces of the workpiece 5 on both sides along the first direction are abutted and clamped by the limiting element 23, the elastic element 24 can be compressed to store potential energy. When the workpiece 5 is cleaned, during the process of disassembling the workpiece 5, the potential energy stored in the elastic element 24 can act on the limiting element 23, so that the limiting element 23 and the clamping piece 22 can be disassembled from the rotating shaft 21, thereby improving the convenience of disassembling the workpiece 5. On the other hand, the elastic element 24, which can be compressed or stretched, can reduce the possibility that the limiting element 23 over-clamps the workpiece 5, which helps to reduce the possibility that the workpiece 5 will be damaged by the limiting element 23 due to over-clamping.
[0034] In one embodiment, please refer to Figure 3 The limiting member 23 includes a limiting block 231 and a clamping plate 232 connected to each other. The limiting block 231 is disposed between the clamping piece 22 and the clamping plate 232 along a first direction. For example, the projected area of the clamping plate 232 on the surface of the workpiece 5 is larger than the projected area of the limiting block 231 on the surface of the workpiece 5, so as to appropriately increase the contact area between the limiting member 23 and the workpiece 5. On the one hand, it can reduce the pressure applied by the limiting member 23 to the surface of the workpiece 5, and reduce the possibility of the limiting member 23 damaging the workpiece 5 due to over-clamping. On the other hand, it can also increase the friction between the limiting member 23 and the surface of the workpiece 5, so as to clamp the workpiece 5 more firmly.
[0035] In one embodiment, please refer to Figure 1 and Figure 2 The radial dimension of the clamping piece 22 is smaller than that of the workpiece 5 in order to reduce the obstruction of the workpiece 5 by the clamping piece 22 during the cleaning process of the cleaning brush 31, so that the bristles of the cleaning brush 31 can directly contact the surface of the workpiece 5 as much as possible and clean the workpiece 5, which is beneficial to improving the cleaning effect of the workpiece 5.
[0036] In one embodiment, please refer to Figure 1 and Figure 2 The bristles of the cleaning brush 31 can be located in the gap between the clamping plate 22 and the corresponding workpiece 5, so that the surface of the workpiece 5 located within the gap range can also be cleaned by the bristles of the cleaning brush 31, thereby increasing the area of the workpiece 5 surface that can be cleaned by the cleaning brush 31, which is beneficial to improving the cleaning effect of the workpiece 5.
[0037] In one embodiment, please refer to Figure 1 and Figure 2The cleaning assembly 3 includes a water pump 32 and spray pipes 33 that are interconnected. The water pump 32 is configured to increase the water pressure within the spray pipes 33, which are spaced apart within the cleaning tank 1 along a first direction. For example, please refer to... Figure 1 and Figure 2 The spray pipes 33 extend from one end of the cleaning tank 1 to the other end in a direction intersecting the first direction. Multiple spray pipes 33 are interconnected and spaced apart within the cleaning tank 1 along the first direction. Under the pressure of the water pump 32, the multiple spray pipes 33 can spray water jets or water mist with a certain pressure. After the cleaning brush 31 finishes cleaning the workpiece 5, the cleaning liquid in the cleaning tank 1 can be emptied. Then, the spray pipes 33 can be controlled to spray water jets or water mist to clean the residual foam (generated by the cleaning brush 31 brushing the surface of the workpiece 5) and residual oil and dust on the surface of the workpiece 5, further improving the cleaning effect of the workpiece 5.
[0038] In one embodiment, please refer to Figure 2 The cleaning device includes a heating element 6, which is configured to increase the temperature of the cleaning fluid to maintain it at an optimal operating temperature, thereby enhancing the fluid's activity and improving its cleaning effect on oil and dust on the surface of the workpiece 5. For example, the heating element 6 can be an electric heating element connected to an external power source, with at least a portion of its structure immersed in the cleaning fluid to increase its temperature.
[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
