Description

Technical Field

[0001] This application belongs to the field of cleaning device technology, and specifically relates to a cleaning device. Background Technology

[0002] Threaded connections are suitable for assembling various products. For example, metal products are typically secured by threaded holes and fasteners. However, during the machining of threaded holes, metal shavings and other foreign objects inevitably remain inside. These foreign objects can prevent fasteners from being effectively tightened, affecting the assembly of products and parts.

[0003] In related technologies, foreign objects are mainly removed manually, which is inefficient and makes it difficult to guarantee cleanliness. Utility Model Content

[0004] This application provides a cleaning device that can improve the cleaning efficiency of threaded holes.

[0005] Embodiments of this application provide a cleaning device, including a base and a cleaning assembly. The base is configured to support a workpiece. The cleaning assembly includes a support, a guide, and an air supply component. The support is disposed on one side of the base. The guide is rotatably disposed on the support and has opposing first and second ends, and a channel passing through the first and second ends. The air supply component is connected to the first end and configured to supply gas into the channel. When the second end of the guide faces the base, it can guide the gas to blow towards the workpiece. Rotation of the guide relative to the support can increase the distance between the second end and the base.

[0006] In the aforementioned cleaning device, by driving the guide member to rotate relative to the support, when the second end of the guide member faces the base, gas can enter the channel and be blown towards the workpiece under the guidance of the channel to clean the workpiece. By driving the guide member to rotate relative to the support, the distance between the second end and the base can be increased, that is, the guide member can be rotated and retracted to facilitate operation on the workpiece on the base. When the workpiece has a threaded hole, the gas is guided into the threaded hole through the channel of the guide member, which can clean foreign objects in the threaded hole. Compared with manual cleaning of foreign objects, the cleaning device described above has a high degree of automation and can improve cleaning efficiency.

[0007] In some embodiments, the first end is rotatably connected to the bracket.

[0008] When it is necessary to operate the workpiece on the base, the second end is driven to rotate around the first end to increase the distance between the second end and the base; while the distance between the second end and the base increases, the distance between the first end and the base remains unchanged, which can prevent the guide from being damaged by collision when the first end gets close to the base.

[0009] In some embodiments, the guide has a first position and a second position and is configured to be rotatable to the first position and the second position. When the guide is in the first position, the second end faces the base. The guide rotates relative to the bracket by an included angle α so that the guide is in the second position, 90°≤α≤180°.

[0010] When the guide is in the first position, the channel can guide the gas to blow towards the workpiece to clean it; when the guide is in the second position, the distance between the guide and the base increases, and the larger the included angle α is, the greater the distance between the second end and the base; when the guide is in the second position, it can be rotated and retracted to leave space for the operator to operate the workpiece on the base.

[0011] In some embodiments, the guide is provided with a connecting block, and the connecting block is provided with a clearance groove; the cleaning assembly further includes a power member and a positioning member, the power member is provided on the bracket, the power member is connected to the connecting block, and the power member is configured to drive the connecting block to extend, retract and rotate; when the connecting block extends, the connecting block can drive the guide to rotate, and when the guide is in the first position, the positioning member is inserted into the clearance groove, and the two side walls of the clearance groove stop the positioning member.

[0012] When the power component drives the connecting block to extend, the connecting block can drive the guide to rotate between the first position and the second position. When the guide rotates to the first position, the positioning component is inserted into the clearance groove. The two side walls of the clearance groove stop the positioning component to limit the relative displacement of the positioning component relative to the connecting block, thereby preventing the guide from deviating from the first position.

[0013] In some embodiments, the connecting block is provided with a protrusion, which is configured to abut against a positioning member when the guide is in the second position. The positioning member is configured to restrict the connecting block from causing the guide to rotate toward the first position.

[0014] When the guide rotates to the second position, the protrusion abuts against the positioning element, and the positioning element can restrict the connecting block from driving the guide to rotate toward the first position.

[0015] In some embodiments, the channel includes an inlet and an outlet, with the inlet located at a first end and the outlet located at a second end; the size of the inlet is larger than the size of the outlet.

[0016] The gas supply unit introduces gas into the channel through the inlet. When the size of the inlet is larger than the size of the outlet, the inlet can accept more gas flow, while the outlet compresses the airflow, increasing the gas pressure blown onto the workpiece and making the gas impact on the workpiece stronger, thus cleaning the workpiece more thoroughly.

[0017] In some embodiments, the cleaning device further includes a lifting assembly, a bracket disposed on the lifting assembly, and the lifting assembly is configured to move the bracket toward the base in a first direction.

[0018] By using the lifting assembly to move the bracket along the first direction, the distance between the second end and the base can be adjusted, thereby adjusting the magnitude of the gas impact force on the workpiece.

[0019] In some embodiments, the base includes a support platform and a movable element. The support platform is configured to support a workpiece, and the movable element is connected to the support platform and configured to drive the support platform to move along a second direction and / or a third direction; the third direction is perpendicular to the second direction and the first direction.

[0020] The moving component drives the carrier platform to move, and the carrier platform moves the workpiece. This allows the second end to correspond to different positions on the workpiece, so that gas can be blown to different positions on the workpiece to clean them.

[0021] In some embodiments, the guide includes a mounting portion and a needle, the needle being detachably connected to the mounting portion.

[0022] By replacing the needles with different models at the mounting section, the size of the outlet can be adjusted to suit different workpieces.

[0023] In some embodiments, the first end is provided with a connector that connects to a channel; the gas supply component is connected to a pipe that is connected to the connector, allowing gas to enter the channel through the pipe and the connector.

[0024] The air supply unit and the guide unit are connected by pipes and connectors, which is convenient and quick to connect. When the guide unit rotates relative to the support, the pipes can rotate with the rotation of the guide unit, without the need to disconnect or reconnect the air supply unit and the guide unit, thus saving operation time and improving the workpiece cleaning efficiency.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0038] Threaded connections are suitable for assembling various products. For example, metal products typically use threaded holes to secure parts, and fasteners are used to connect these threaded holes. However, during the machining of threaded holes, metal shavings and other foreign objects inevitably remain inside. These foreign objects can prevent fasteners from being effectively tightened, affecting the assembly of products and parts. In related technologies, the main method of cleaning these foreign objects is manual, which is inefficient and makes it difficult to guarantee cleanliness.

[0039] Embodiments of this application provide a cleaning device, including a base and a cleaning assembly. The base is configured to support a workpiece. The cleaning assembly includes a support, a guide, and an air supply component. The support is disposed on one side of the base. The guide is rotatably disposed on the support and has opposing first and second ends, and a channel passing through the first and second ends. The air supply component is connected to the first end and configured to supply gas into the channel. When the second end of the guide faces the base, it can guide the gas to blow towards the workpiece. Rotation of the guide relative to the support can increase the distance between the second end and the base.

[0040] In the aforementioned cleaning device, by driving the guide member to rotate relative to the support, when the second end of the guide member faces the base, gas can enter the channel and be blown towards the workpiece under the guidance of the channel to clean the workpiece. By driving the guide member to rotate relative to the support, the distance between the second end and the base can be increased, that is, the guide member can be rotated and retracted to facilitate operation on the workpiece on the base. When the workpiece has a threaded hole, the gas is guided into the threaded hole through the channel of the guide member, which can clean foreign objects in the threaded hole. Compared with manual cleaning of foreign objects, the cleaning device described above has a high degree of automation and can improve cleaning efficiency.

[0041] The embodiments of this application will be further described below with reference to the accompanying drawings. Unless otherwise specified, the various embodiments in this application can be combined with each other.

[0042] Please see Figure 1 and Figure 2 An embodiment of this application provides a cleaning device 100, including a base 10 and a cleaning assembly 20, wherein the base 10 is configured to support a workpiece 200. Along a first direction Z, the cleaning assembly 20 is located above the base 10 and is configured to blow gas toward the workpiece 200 to clean the workpiece 200.

[0043] In some embodiments, the cleaning device 100 further includes a lifting assembly (not shown). The lifting assembly is located above the base 10 along a first direction Z. A cleaning assembly 20 is disposed on the lifting assembly, and the lifting assembly is configured to move the cleaning assembly 20 toward the base 10 along the first direction Z, thereby adjusting the distance between the cleaning assembly 20 and the base 10, thereby adjusting the magnitude of the impact force of the gas on the workpiece 200.

[0044] In some embodiments, the lifting assembly is the spindle of a CNC machine tool.

[0045] In some embodiments, the cleaning device 100 further includes a control module (not shown) configured to control the cleaning assembly 20 to blow out gas.

[0046] In some embodiments, the workpiece 200 has a threaded hole 2001, and the gas blown out by the cleaning component 20 acts on the threaded hole 2001 to blow out foreign objects inside the threaded hole 2001. The gas is a positive pressure gas.

[0047] In some embodiments, the base 10 includes a support platform 11 and a movable element 12. The support platform 11 is configured to support the workpiece 200. The movable element 12 is connected to the support platform 11 and configured to drive the support platform 11 to move along a second direction X and / or a third direction Y.

[0048] In some embodiments, the third direction Y is perpendicular to the second direction X and the first direction Z. The first direction Z is a vertical direction, and the second direction X and the third direction Y are horizontal directions.

[0049] The moving component 12 drives the carrier platform 11 and the workpiece 200 to move horizontally, so that the cleaning component 20 can correspond to different positions of the workpiece 200, thereby allowing gas to be blown to different positions of the workpiece 200. In this way, the gas blown out by the cleaning component 20 can be blown to the threaded holes 2001 of different workpieces 200, or to different threaded holes 2001 of the same workpiece 200.

[0050] In some embodiments, the moving component 12 includes two linear drive structures connected to each other. The support platform 11 is disposed on either of the linear drive structures. The two linear drive structures are respectively driven along the second direction X and the third direction Y, enabling the support platform 11 to move along the second direction X and the third direction Y. The linear drive structure includes a slide cylinder or an electric slide rail, which is not limited in this application.

[0051] Please see Figures 1 to 4 In some embodiments, the cleaning assembly 20 includes a bracket 21, a guide 22, and an air supply component 23. The bracket 21 is fixedly connected to the lifting assembly. The guide 22 is rotatably disposed on the bracket 21 and has opposing first ends 22a and second ends 22b, and a channel 2201 passing through the first ends 22a and 22b. The air supply component 23 is connected to the first end 22a. The air supply component 23 is connected to a control module to supply gas into the channel 2201 under the control of the control module.

[0052] Please see Figure 1 and Figure 3When the second end 22b faces the base 10, the air supply component 23 can supply gas into the channel 2201. Under the guidance of the guide component 22, the gas is blown into the threaded hole 2001 of the workpiece 200 to clean the foreign objects in the threaded hole 2001. At this time, the guide component 22 is in the first position. Compared with manual cleaning of foreign objects, the cleaning device 100 has a high degree of automation in cleaning foreign objects and can improve the cleaning efficiency of the threaded hole 2001.

[0053] In some embodiments, when the guide 22 is in the first position, the distance between the second end 22b and the opening of the threaded hole 2001 is 0.5mm-2mm, so that the gas has a stronger impact force on the threaded hole 2001, and foreign objects in the threaded hole 2001 can be blown out from the opening.

[0054] Please see Figure 2 and Figure 4 When the guide 22 in the first position rotates at an angle α relative to the bracket 21, the distance between the second end 22b and the base 10 in the first direction Z increases. At this time, the guide 22 is in the second position and the guide 22 is rotated and retracted.

[0055] When the guide 22 is in the second position, the workpiece 200 on the base 10 can be operated, for example, the cleaned workpiece 200 can be removed by an operator or a robot, or the workpiece 200 to be cleaned can be placed, in order to prevent collision with the guide 22 from causing damage or breakage to the guide 22.

[0056] By driving the guide 22 to rotate between the first position and the second position, the usage state of the cleaning device 100 can be switched. When the workpiece 200 needs to be cleaned, the guide 22 is driven to rotate to the first position. When the base 10 needs to be loaded or unloaded, the guide 22 is driven to rotate to the second position. The guide 22 can be folded up in a limited space to increase the distance between the base 10 and the guide 22 in the first direction Z, leaving operating space for loading and unloading the base 10.

[0057] In some embodiments, 90°≤α≤180°. The larger the included angle α, the greater the distance between the second end 22b and the base 10 in the first direction Z.

[0058] The side on which the operator or robot removes the cleaned workpiece 200 or places the workpiece 200 to be cleaned is defined as the outer side of the base 10, and the side opposite to the outer side is defined as the inner side of the base 10; the guide 22 rotates relative to the bracket 21 toward the inner side of the base 10 to prevent the guide 22 from interfering with the operation of the operator or robot.

[0059] Please combine Figure 3 and Figure 4 In some embodiments, the first end 22a is rotatably connected to the bracket 21.

[0060] During the process of the guide 22 rotating from the first position to the second position, the second end 22b rotates around the first end 22a toward the inside of the base 10, that is, the guide 22 will rotate and fold toward the inside of the base 10, and the guide 22 will not extend to the outside of the base 10 during the rotation and folding process, so as to prevent the guide 22 from interfering with the operation of the operator or the robot arm.

[0061] Please see Figure 4 In some embodiments, the included angle α is configured to be 90°.

[0062] Please combine Figure 3 and Figure 4 During the process of the guide 22 rotating from the first position to the second position, the distance between the second end 22b and the base 10 gradually increases along the first direction Z, while the distance between the first end 22a and the base 10 remains unchanged. When the guide 22 in the first position rotates 90° relative to the bracket 21, the guide 22 is in the second position, at which time the distance between the first end 22a and the second end 22b and the base 10 in the first direction Z is the same.

[0063] Please see Figure 5 In some embodiments, the channel 2201 includes an inlet 2202 and an outlet 2203, with the inlet 2202 located at a first end 22a and the outlet 2203 located at a second end 22b; the size of the inlet 2202 is larger than the size of the outlet 2203.

[0064] The gas supply component 23 introduces gas into the channel 2201 through the inlet 2202. When the size of the inlet 2202 is larger than the size of the outlet 2203, the inlet 2202 can accept more gas flow, while the outlet 2203 compresses the airflow, increasing the gas pressure blown toward the workpiece 200, making the gas impact on the workpiece 200 stronger, and thus cleaning the workpiece 200 more thoroughly.

[0065] In some embodiments, the cleaning assembly 20 further includes a power member 24 disposed on the bracket 21. The power member 24 is configured to drive the second end 22b of the guide 22 to rotate about the first end 22a, so that the guide 22 rotates between a first position and a second position.

[0066] Please see Figure 6 In some embodiments, the power component 24 is connected to the connecting block 223 and configured to drive the connecting block 223 to extend, retract, and rotate. The cleaning assembly 20 also includes a positioning component 25, which is fixedly mounted on the bracket 21. The first end 22a of the guide 22 is fixedly connected to a connecting block 223, and the connecting block 223 is provided with a clearance groove 2231, the two sidewalls of which are spaced apart along the third direction Y.

[0067] When the power component 24 drives the connecting block 223 to extend, the connecting block 223 moves away from the bracket 21 along the second direction X. At this time, the positioning component 25 does not contact the connecting block 223, and the connecting block 223 can drive the guide 22 to rotate between the first position and the second position under the drive of the power component 24. Please refer to [link / reference]. Figure 3 When the guide 22 rotates to the second end 22b facing the base 10, the power member 24 can drive the connecting block 223 to retract, so that the connecting block 223 moves towards the bracket 21 along the second direction X. At this time, the guide 22 is in the first position, and the positioning member 25 is inserted into the relief groove 2231. The two side walls of the relief groove 2231 stop the positioning member 25 to limit the relative displacement of the positioning member 25 relative to the connecting block 223, which would cause the guide 22 to deviate from the first position.

[0068] Please see Figure 4 In some embodiments, the connecting block 223 is fixedly provided with a protrusion 2232 that protrudes toward the positioning member 25. When the guide member 22 in the first position rotates 90° relative to the bracket 21, the power member 24 can drive the connecting block 223 to retract, so that the connecting block 223 moves toward the bracket 21 along the second direction X. At this time, the guide member 22 is in the second position, and the positioning member 25 abuts against the protrusion 2232 to restrict the connecting block 223 from rotating toward the first position.

[0069] In some embodiments, the power component 24 is a rotary telescopic cylinder. The power component 24 may also include a slide cylinder and a rotary cylinder. The rotary cylinder is disposed on the slide cylinder. The rotary cylinder is used to fix the connecting block 223 and drive the connecting block 223 to rotate. The slide cylinder is used to drive the rotary cylinder to move the connecting block 223 along the second direction X, so that the connecting block 223 can both extend and rotate.

[0070] In some embodiments, the positioning element 25 is a positioning pin.

[0071] Please combine Figures 3 to 5 In some embodiments, the guide 22 is rod-shaped. The guide 22 includes a mounting portion 221 and a needle 222, the needle 222 being detachably connected to the mounting portion 221. A channel 2201 extends through the mounting portion 221 and the needle 222 along a first direction Z.

[0072] By replacing the needle 222 with a different model to the mounting part 221, the size of the outlet 2203 can be adjusted to fit threaded holes 2001 of different sizes.

[0073] In some embodiments, the needle 222 is threaded to the mounting portion 221.

[0074] Please see Figure 3 and Figure 4In some embodiments, the gas supply component 23 is provided with a pipe 231. The first end 22a is provided with a connector 224, which connects to the channel 2201. The pipe 231 is connected to the connector 224, allowing gas to enter the channel 2201 through the pipe 231 and the connector 224.

[0075] The air supply component 23 and the guide component 22 are connected by a pipe 231 and a connector 224, which is convenient and quick to connect. When the guide component 22 rotates relative to the support 21, the pipe 231 can rotate with the rotation of the guide component 22, without having to disconnect or reconnect the air supply component 23 and the guide component 22, thus saving operation time and improving the cleaning efficiency of the workpiece 200.

[0076] In some embodiments, the control module includes a controller and a solenoid valve (not shown) that are electrically connected to each other.

[0077] In some embodiments, the air supply component 23 includes a compressor and an air tank (not shown). The compressor compresses the air volume and stores it in the air tank. A pipe 231 connects the air tank and the interface. A solenoid valve is located on the pipe 231. When the solenoid valve receives a signal from the controller, it opens or closes instantaneously. When the solenoid valve is continuously open, the air supply component 23 can continuously blow air onto the workpiece 200. When the solenoid valve is periodically opened, the air supply component 23 can intermittently blow air onto the workpiece 200. The controller is a programmable logic controller (PLC) or a timer.

[0078] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
