Detailed implementation manners

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In order to solve the technical problem in the prior art that the dust cleaning section 320 cannot contact the outer wall of the electrical component to be dust cleaned after rotation, resulting in poor dust cleaning effect, the present invention provides a dust cleaning device, which can realize that the dust cleaning section 320 capable of contacting the outer circumferential wall of the workpiece is connected to the elastic section 334, so that the dust cleaning section 320 can slide relative to the workbench 100 driven by the elastic section 334, so that the dust cleaning section 320 can always actively abut against the workpiece, thereby increasing the degree of fit between the dust cleaning section 320 and the side wall of the workpiece, and ensuring that the dust cleaning section 320 contacts the outer circumferential wall of the rotated workpiece, improving the dust cleaning effect.

[0021] It should be noted that the dust cleaning device of the present invention is used in but not limited to the technical field of weak current engineering construction. For the convenience of description, in the present invention, only the case where the dust cleaning device is applied to the equipment in the technical field of weak current engineering construction is taken as an example for description, and the principle of the dust cleaning device applied to other types of equipment is substantially the same as that applied to the equipment in the technical field of weak current engineering construction, and will not be elaborated here one by one.

[0022] Please refer to Figures 1 to 5 , Figure 1 , Figure 2 is a schematic structural diagram of a dust cleaning device in an embodiment of the present invention. The dust cleaning device includes: a workbench 100, a clamping assembly 200 and a dust cleaning assembly. The clamping assembly 200 is rotatably connected to the workbench 100 and can rotate relative to the workbench 100 for clamping a workpiece. The dust cleaning assembly 300 includes at least one dust cleaning part 310. The dust cleaning part 310 includes a dust cleaning section 320 and an elastic section 334. The dust cleaning section 320 is arranged opposite to the workpiece and can abut against the workpiece. The elastic section 334 is connected to the dust cleaning section 320 and the workbench 100 for driving the dust cleaning section 320 to slide relative to the workbench 100 and making the dust cleaning section 320 always actively abut against the workpiece.

[0023] In this device, a clamping assembly 200 for clamping a workpiece is provided on a workbench 100. The clamping assembly 200 is used to drive the workpiece relative to the workbench 100. At least one dust cleaning part 320 is arranged relative to the workpiece and is connected to the workbench 100 via an elastic part 334. The dust cleaning part 320 can slide relative to the workbench 100 under the drive of the elastic part 334 and always contacts the rotated workpiece, so as to remove the dust on the surface of the workpiece.

[0024] Further, the clamping assembly 200 is a common and easily purchasable tooling fixture device on the market. The clamping assembly 200 has an adjustable clamping gap. The user first enlarges the size of the clamping gap, then places the workpiece to be dust-cleaned into the clamping gap, and finally reduces the clamping gap to fix the workpiece to be dust-cleaned. Here, the clamping assembly 200 can also rotate relative to the workbench 100 under the drive of a motor. The specific structure here can refer to the Chinese utility model patent with the publication number: CN218873110U, titled: A dust cleaner for weak current engineering construction. Here, the clamping assembly 200 belongs to the conventional settings well-known to those skilled in the art and will not be elaborated here too much.

[0025] Further, the dust cleaning part 320 here is a common and easily purchasable cleaning roller brush, brush, and sponge block on the market. The dust cleaning part 320 is in a long strip shape and has an anti-static function to prevent dust from adhering to the surface of the dust cleaning part 320. Here, this belongs to the conventional settings well-known to those skilled in the art and will not be elaborated here too much.

[0026] In this embodiment, as Figure 1 、 Figure 2 shown, this device further includes a dust removal assembly 400. The dust removal assembly 400 includes a dust removal cover 410, a negative pressure part 420, a dust collection box 430, a filter screen 440, and a knocking part 450.

[0027] Among them, as one implementation method, as Figure 2 、 Figure 3 shown, the dust cleaning assembly 300 further includes a sliding part 330. The sliding part 330 includes at least one fixed seat 331, a mounting seat 332, and at least one sliding rod 333. The fixed seat 331 is connected to the inner wall of the dust removal cover 410. The mounting seat 332 is arranged relative to the workpiece, and the dust cleaning part 320 is detachably connected to the mounting seat 332. The fixed seat 331 is provided with a sliding groove, and one end of the sliding rod 333 is connected to the mounting seat 332 and the other end is slidably inserted into the fixed seat 331.

[0028] The sliding rod 333 cooperates with the sliding groove on the fixed seat 331 to form a sliding connection, so that the dust cleaning part 320 is slidably connected to the fixed seat 331 and the dust removal cover 410 via the mounting seat 332 and the sliding rod 333.

[0029] Further, the dust cleaning part 320 is arranged opposite to the workpiece and can slide closer to or away from the workpiece relative to the dust removal cover 410. When the workpiece rotates, the dust cleaning part 320 can adaptively move relative to the surface of the workpiece to ensure effective abutment against the side wall of the workpiece.

[0030] Further, the fixing seats 331 and the sliding rods 333 are arranged in one-to-one correspondence, and a plurality of fixing seats 331 are arranged at intervals in sequence along the length direction of the dust cleaning part 320.

[0031] In addition, in one embodiment, a clamping groove is formed in the length direction of the mounting seat 332, and the dust cleaning part 320 can be elastically clamped in the clamping groove to realize the detachable connection between the dust cleaning part 320 and the mounting seat 332, which is convenient for the user to clean or replace the dust cleaning part 320, and will not be elaborated here too much.

[0032] As one implementation manner, as Figure 3 shown, the elastic part 334 includes at least one spring. The spring is sleeved on the sliding rod 333, and one end of the spring is connected to the dust cleaning part 320 and the other end is connected to the fixing seat 331, so as to drive the dust cleaning part 320 to slide relative to the fixing seat 331 and automatically reset.

[0033] The elastic restoring force generated by the spring is used to push the sliding rod 333 to slide relative to the fixing seat 331 to ensure that the dust cleaning part 320 can actively abut against the surface of the workpiece.

[0034] Further, here the spring can also be replaced by an elastic block or an elastic sheet, which will not be elaborated here too much.

[0035] In this embodiment, as Figure 2 、 Figure 3 shown, the dust cleaning assembly 300 further includes at least one nozzle 335 and an air pump 336. The nozzle 335 is arranged opposite to the workpiece and is connected to the mounting seat 332. The air pump 336 is connected to the dust removal cover 410, and the air outlet end of the air pump 336 is communicated with the inside of the nozzle 335.

[0036] By further arranging at least one nozzle 335 on one side of the dust cleaning part 320 and using the air pump 336 to supply air into the nozzle 335 to generate high-speed gas, the dust on the surface of the workpiece can be assisted to be blown off, and the dust cleaning effect can be improved.

[0037] Further, here the nozzle 335 and the air pump 336 are both common and easy-to-purchase devices in the market, which are conventional settings well-known to those skilled in the art, and will not be elaborated here too much.

[0038] As one implementation manner, as Figure 2As shown, the number of nozzles 335 is two. The two nozzles 335 are spaced along the length direction of the dust cleaning part 320. The dust cleaning assembly 300 further includes a plurality of connecting hoses 337. The air outlet end of the air pump 336 is connected to the inside of the nozzle 335 via the connecting hose 337.

[0039] By sequentially arranging a plurality of nozzles 335 at intervals along the length direction of the dust cleaning part 320, the dust cleaning effect can be effectively improved. The connecting hose 337 is used to realize the connection between the nozzle 335 and the air outlet end of the air pump 336.

[0040] Furthermore, the number of the dust cleaning assemblies 300 in this device is two. The two dust cleaning parts 320 are symmetrically distributed with the rotation axis of the clamping assembly 200 as the center line, and are respectively connected to both sides of the dust collection hood 410. And the two dust cleaning parts 320 can respectively abut against the outer wall of the workpiece to improve the dust cleaning effect.

[0041] Among them, as an implementation manner, as Figure 1 、 Figure 2 shown, the dust collection hood 410 is connected to the workbench 100 and has an opening relative to the clamping assembly 200. The dust collection hood 410 covers the clamping assembly 200 via the opening. The air inlet end of the negative pressure part 420 is connected to the inside of the dust collection hood 410.

[0042] The dust collection hood 410 can prevent the dust on the surface of the workpiece from being swept off by the dust cleaning part 320 and flying everywhere. The negative pressure generated by the negative pressure part 420 is used to centrally collect the flying dust, which can purify the working and production environment.

[0043] Furthermore, the negative pressure part 420 here is a common and easily purchasable device on the market, which is a conventional setting well-known to those skilled in the art, and will not be elaborated here too much.

[0044] Furthermore, the dust collection hood 410 is arranged above the clamping assembly 200 and the workpiece through a bracket. The negative pressure part 420 is connected to the bracket to form a stable structure, which will not be elaborated here too much.

[0045] Among them, as an implementation manner, as Figure 1 、 Figure 2 and Figure 4 shown, the dust collection box 430 is connected to the workbench 100. The inside of the dust collection box 430 is hollow and is connected to the inside of the dust collection hood. The negative pressure part 420 is connected to the dust collection box 430, and its air inlet end is placed inside the dust collection box 430. The filter screen 440 is arranged relative to the air inlet end of the negative pressure part 420 and is connected to the inner wall of the dust collection box 430. The knocking part 450 is arranged relative to the filter screen 440 and is connected to the dust collection box 430, and the knocking part 450 can reciprocally impact the filter screen 440.

[0046] The filter screen 440 can separate and filter out the dust entering the negative pressure member 420 of the dust box 430, and temporarily store the dust in the dust box 430 for subsequent centralized processing.

[0047] Furthermore, by repeatedly knocking the filter 440 with the knocking piece 450, dust can be prevented from accumulating on the filter 440, thereby preventing the filtering effect from being affected and improving the efficiency of dust cleaning.

[0048] As an implementation method, Figure 4 , Figure 5 As shown, the knocking member 450 includes a rotating rod 451, a knocking part 452 and a driving part 453. The rotating rod 451 is rotatably connected to the inner wall of the dust box 430. The knocking part 452 is arranged relative to the filter 440 and is connected to one end of the rotating rod 451. The driving part 453 is connected to the dust box 430 and the other end of the rotating rod 451, and is used to drive the knocking part 452 to reciprocately knock the filter 440.

[0049] By intermittently moving the other end of the rotating rod 451 by the driving part 453, the rotating rod 451 can be driven to rotate around the rotation axis between the rotating rod 451 and the inner wall of the dust collecting box 430, so that the knocking part 452 located at one end can repeatedly knock the filter 440 to achieve the purpose of shaking off the dust.

[0050] Furthermore, the weight of the knocking part 452 at one end of the rotating rod 451 is greater than the weight of the other end, so the knocking part 452 can automatically reset after the rotation, which will not be described in detail here.

[0051] Furthermore, a pull-out drawer is provided inside the dust box 430. The pull-out drawer is provided below the filter 440 and is slidably connected to the side wall of the dust box 430. After use, the user can regularly pull the pull-out drawer out of the dust box 430 to dump the dust collected in the pull-out drawer to avoid dust accumulation affecting the cleaning and dust removal effect. The pull-out drawer here is a common and easy-to-purchase equipment on the market. It is a conventional setting known to technical personnel in this field and will not be elaborated here.

[0052] As an implementation method, Figure 5 As shown, the driving part 453 includes a cam 4531 and a driving motor 4532. The cam 4531 is rotatably connected to the inner wall of the dust box 430 and can abut against the other end of the rotating rod 451. The fixed end of the driving motor 4532 is connected to the dust box 430, and the output shaft is connected to the rotating axis of the cam 4531, which is used to drive the cam 4531 relative to the inner wall of the dust box 430 and move the other end of the rotating rod 451 to rotate in a direction close to the filter 440.

[0053] The driving motor 4532 is provided to drive the cam 4531 to rotate, and the rotated cam 4531 can intermittently abut against the rotating rod 451 to drive the rotating rod 451 to rotate.

[0054] Furthermore, the driving part 453 here can also be a crank slider structure composed of a rotating disk and a connecting rod, and the reciprocating sliding of the crank slider is used to drive the rotating rod 451 to rotate relative to the dust box 430, thereby realizing reciprocating knocking of the filter 440. The crank slider structure here is a common and easy-to-purchase device on the market. It is a conventional setting known to technical personnel in this field and will not be elaborated here.

[0055] As an implementation method, Figure 5 As shown, the knocking member 450 further includes an abutting sleeve 454 , which is detachably mounted on the knocking portion 452 .

[0056] The abutting sleeve 454 is provided to reduce the impact force of the knocking portion 452 on the filter screen 440 .

[0057] Furthermore, in some embodiments, the abutment sleeve 454 is elastic, for example, a rubber sleeve, a polyurethane sleeve or a polyethylene sleeve, which will not be described in detail here.

[0058] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the present invention is described in detail: A clamping assembly 200 for clamping a workpiece is provided on the workbench 100, and the clamping assembly 200 is used to drive the workpiece to be set relative to the workbench 100. At least one cleaning section 320 is set relative to the workpiece and is connected to the workbench 100 via an elastic section 334. The cleaning section 320 can slide relative to the workbench 100 driven by the elastic section 334, and is always in contact with the rotated workpiece, so as to remove dust from the surface of the workpiece. Compared with the prior art, it is possible to connect the cleaning section 320 that can contact the circumferential outer wall of the workpiece with the elastic section 334, so that the cleaning section 320 can slide relative to the workbench 100 driven by the elastic section 334, so that the cleaning section 320 can always be movably abutted against the workpiece, thereby increasing the fit between the cleaning section 320 and the side wall of the workpiece, and ensuring that the cleaning section 320 is in contact with the circumferential outer wall of the rotated workpiece, thereby improving the cleaning effect.

[0059] The specific working process of the present invention, when in use, first place the workpiece to be dust-cleaned into the clamping gap of the clamping assembly 200, and adjust the size of the clamping gap to fix the workpiece to be dust-cleaned; then adjust the position of the workpiece so that the two dust-cleaning parts 320 can respectively abut against the side walls of the workpiece to be dust-cleaned. Then start the negative pressure part 420 so that the negative pressure part 420 can generate a negative pressure suction force to suck away the dust. At the same time, start the air pump 336 to blow air to the workpiece through the nozzle 335. Finally, start the motor on the clamping assembly 200 that can drive the clamping assembly 200 to rotate relative to the workbench 100, so that the workpiece to be dust-cleaned rotates relative to the dust-cleaning part 320, which can remove the dust on the surface of the workpiece to be dust-cleaned and collect the dust in the dust collection box 430, and can improve the dust-cleaning effect on the surface of the workpiece to be dust-cleaned.

[0060] Through the above structure, the device can solve the technical problem in the prior art that the dust-cleaning part 320 cannot contact with part of the outer wall of the electrical component to be dust-cleaned after rotation, which easily leads to poor dust-cleaning effect.

[0061] The above specific embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention shall be included in the protection scope of the claims of the present invention.
