Description

Technical Field

[0001] This application relates to the technical field of dust removal devices, and particularly relates to a dust removal equipment. Background Art

[0002] When processing electronic products such as marking and welding, it is necessary to remove dust such as welding fumes and welding slag generated during product processing to avoid adverse effects of the welding fumes and welding slag on the processing effect.

[0003] Currently, a common practice is to set multiple air outlets along the processing path of the product. The multiple air outlets are connected to one air supply device or are respectively connected to multiple air supply devices and discharge the dust removal gas simultaneously. When the multiple air outlets are connected to one air supply device, the wind force is weak after the dust removal gas generated by one air supply device is discharged through the multiple air outlets simultaneously, thus affecting the dust removal effect. When the multiple air outlets are respectively connected to multiple air supply devices, since the air supply devices are expensive, the dust removal cost is increased. Utility Model Content

[0063] Please refer to Figure 1 , an embodiment of the present application provides a dust removal device 100 for removing dust from a product (not shown in the figure). Among them, the product can be a circuit board, a housing, etc. of electronic devices such as mobile phones and tablet computers. For the convenience of understanding and description, an embodiment of the present application takes the housing of a mobile phone as an example, and defines the first direction as Figure 1 and Figure 2 the X-axis direction shown in Figure 1 and Figure 2 the Y-axis direction shown in

[0064] Please refer to Figure 1 and Figure 2 , in this embodiment, the dust removal device 100 includes a base 10, a dust removal member 20, a rotating member 30, a gas supply joint 40, a rotation driving mechanism 50, and a positioning assembly 60.

[0065] The dust removal member 20 is provided on the base 10 and extends along the first direction. The dust removal member 20 is provided with a receiving hole 21 that extends along the first direction and penetrates both ends of the dust removal member 20. A plurality of air blowing holes 22 that are arranged at intervals along the first direction and communicate with the receiving hole 21 are also provided on the circumferential side wall of the dust removal member 20.

[0066] The rotating member 30 is rotatably provided in the receiving hole 21 and extends along the first direction. One end of the rotating member 30 is provided with an air delivery channel 34 that extends along the first direction toward the other end of the rotating member 30. A plurality of communication holes 321 that are arranged along the first direction and communicate with the air delivery channel 34 are provided on the circumferential side wall of the rotating member 30. The plurality of communication holes 321 are sequentially staggered along the circumferential direction of the rotating member 30 and respectively correspond to the plurality of air blowing holes 22 one by one, and each air blowing hole 22 is located on the movement track of the corresponding communication hole 321.

[0067] The gas supply joint 40 is inserted into the air delivery channel 34. One end of the gas supply joint 40 away from the air delivery channel 34 is connected to an external gas supply device (not shown in the figure). The gas supply joint 40 is used to deliver gas to the air delivery channel 34.

[0068] The rotation driving mechanism 50 is connected to one end of the rotating member 30 away from the air supply joint 40. The rotation driving mechanism 50 is used to drive the rotating member 30 to rotate, so that a plurality of communication holes 321 are sequentially communicated with the corresponding air blowing holes 22, so that gas is discharged through a group of connected communication holes 321 and air blowing holes 22 for dust removal.

[0069] The positioning assembly 60 is arranged on one side of the dust removal member 20 and is arranged opposite to a plurality of air blowing holes 22. The positioning assembly 60 is used to carry and position the product to be dusted.

[0070] In this embodiment, the dust removal device 100 removes dust from the product when the processing device (not shown in the figure) performs processing such as marking and welding on the product. The first direction is the extending direction of the processing path of the product. When the processing device processes the product and the dust removal device 100 removes dust from the product, first, the product is placed on the positioning assembly 60 for positioning, and a plurality of air blowing holes 22 are respectively opposite to a plurality of processing positions of the product. Then, the processing device processes the product. Along with the change of the processing position of the product by the processing device, the rotation driving mechanism 50 drives the rotating member 30 to rotate, and a group of communication holes 321 corresponding to the current processing position and the air blowing holes 22 are communicated, and the remaining communication holes 321 and the corresponding air blowing holes 22 are all misaligned and not communicated, and the gas is discharged through a group of connected communication holes 321 and air blowing holes 22 for dust removal. Thus, the dust removal device 100 of the embodiment of the present application can use one air supply device to specifically provide dust removal gas with a large wind force according to the change of the specific processing position of the product, thereby improving the dust removal effect and reducing the dust removal cost.

[0071] In this embodiment, the air supply device can be an ion blower. The ion wind blown by the ion blower can effectively eliminate static electricity while removing dust, which is beneficial to improving the quality of processing the product by the processing device.

[0072] In this embodiment, the base 10 includes a base plate 11, two fixing frames 12 and a connecting plate 13. The two fixing frames 12 are arranged on the base plate 11 at intervals along the first direction. Both ends of the dust removal member 20 are respectively connected to the two fixing frames 12. The connecting plate 13 is arranged on the base plate 11 and is located on one side of the dust removal member 20. The rotation driving mechanism 50 is connected to the connecting plate 13. Thus, it is convenient to install the dust removal member 20 and the rotation driving mechanism 50.

[0073] In this embodiment, the dust removal member 20 is cylindrical. In some other embodiments, the dust removal member 20 can also be of other shapes, such as the cross-sectional shape of the dust removal member 20 is rectangular, triangular, etc. The embodiment of the present application does not make specific limitations on this.

[0074] In this embodiment, the gas delivery channel 34 is a blind hole. In some other embodiments, the gas delivery channel 34 can also be a through hole, but a plugging member (not shown in the figure) needs to be provided to plug one end of the gas delivery channel 34 away from the gas supply joint 40 to prevent air leakage from the gas delivery channel 34. The embodiments of the present application do not make specific limitations on this.

[0075] In this embodiment, a plurality of air blowing holes 22 are arranged at equal intervals along the first direction on the circumferential side wall of the dust removing member 20, which is beneficial to improving the coverage area of the plurality of air blowing holes 22.

[0076] In this embodiment, a plurality of communication holes 321 are arranged in sequence at equal intervals and staggered along the circumferential direction of the rotating member 30, so as to facilitate the rotation driving mechanism 50 to drive the rotating member 30 to rotate to accurately control the corresponding communication holes 321 to communicate with the air blowing holes 22.

[0077] In this embodiment, when the number of both the air blowing holes 22 and the communication holes 321 is N, the angle between the axial sections of the rotating member 30 passing through two adjacent communication holes 321 is 360° / (N + 1), and the rotating member 30 is provided with N + 1 rotation positions (not shown in the figure), where N rotation positions respectively correspond to N communication holes 321, and the other rotation position is a closed position. For example, when the number of both the air blowing holes 22 and the communication holes 321 is five, the angle between the axial sections of the rotating member 30 passing through two adjacent communication holes 321 is 60 degrees, and the rotating member 30 is provided with six rotation positions, where five rotation positions respectively correspond to five communication holes 321, and the other rotation position is a closed position. When the rotating member 30 rotates to the rotation position corresponding to any one of the communication holes 321, the corresponding group of communication holes 321 and air blowing holes 22 communicate. When the rotating member 30 rotates to the closed position, all the communication holes 321 and the corresponding air blowing holes 22 are misaligned, and gas cannot be discharged from any one of the air blowing holes 22.

[0078] In this embodiment, the dust removing device 100 further includes two bearings 70, and the two bearings 70 are respectively arranged at both ends of the receiving hole 21 and sleeved on both ends of the rotating member 30. In this way, it is beneficial to improve the smoothness and stability of the rotation driving mechanism 50 driving the rotating member 30 to rotate.

[0079] Please refer to Figure 3 , in this embodiment, the receiving hole 21 includes a rotating section 211 and two receiving sections 212 respectively connected to both ends of the rotating section 211. The diameters of the two receiving sections 212 are larger than the diameter of the rotating section 211, and the two bearings 70 are respectively arranged in the two receiving sections 212. In this way, it is convenient to install the bearings 70.

[0080] In this embodiment, a plurality of air-blowing protrusions 23 are convexly provided on the peripheral side wall of the dust removing member 20 and are arranged at intervals in the first direction. The plurality of air-blowing protrusions 23 respectively correspond to the plurality of air-blowing holes 22 one by one, and the plurality of air-blowing holes 22 respectively pass through the plurality of air-blowing protrusions 23. By arranging the plurality of air-blowing holes 22 to respectively pass through the plurality of air-blowing protrusions 23, the lengths of the plurality of air-blowing holes 22 are increased, so that the gas converges closer to the product after passing through the corresponding air-blowing holes 22, which is beneficial to improving the dust removal effect of the dust removal device 100.

[0081] Please refer to again Figure 1 and Figure 2 In this embodiment, the rotating member 30 includes a first connecting portion 31, a rotating portion 32, and a second connecting portion 33 that are sequentially connected in the first direction. The first connecting portion 31, the rotating portion 32, and the second connecting portion 33 are all cylindrical. The diameters of the first connecting portion 31 and the second connecting portion 33 are both smaller than the diameter of the rotating portion 32. The air delivery channel 34 is opened on the side of the first connecting portion 31 facing away from the rotating portion 32 and extends towards the second connecting portion 33. The plurality of communication holes 321 are all opened on the peripheral side wall of the rotating portion 32. Two bearings 70 are respectively sleeved on the first connecting portion 31 and the second connecting portion 33. In this way, it is convenient to connect the rotating member 30 and the bearings 70.

[0082] In this embodiment, a plurality of mounting grooves 322 are further opened on the peripheral side wall of the rotating member 30 and are arranged in the first direction. The plurality of mounting grooves 322 respectively correspond to the plurality of communication holes 321 one by one, and the plurality of mounting grooves 322 are respectively arranged around the corresponding communication holes 321. The dust removal device 100 further includes a plurality of sealing members 80. The plurality of sealing members 80 are respectively arranged in the plurality of mounting grooves 322 and are in contact with the inner wall of the receiving hole 21. The plurality of sealing members 80 can all be sealing rings. By arranging the plurality of sealing members 80 to be respectively arranged in the plurality of mounting grooves 322 and in contact with the inner wall of the receiving hole 21, a closed space is formed between the sealing members 80 and the inner wall of the receiving hole 21. Only when the rotating member 30 rotates to the rotation position corresponding to any one of the communication holes 321, the gas can be discharged through a set of connected communication holes 321 and air-blowing holes 22 for dust removal. Moreover, the sealing members 80 can prevent the gas from entering the receiving hole 21 through other communication holes 321 and further being discharged through other air-blowing holes 22, thereby ensuring the wind force magnitude of the gas discharged through a set of connected communication holes 321 and air-blowing holes 22, and further being beneficial to improving the dust removal effect of the dust removal device 100.

[0083] In this embodiment, the difference between the diameter of the rotating section 211 and the diameter of the rotating portion 32 is less than or equal to 1 mm, so that the sealing members 80 are in closer contact with the inner wall of the receiving hole 21, which is beneficial to improving the sealing effect of the sealing members 80.

[0084] In some other embodiments, without providing the seal 80, the inner diameter of the rotating section 211 may be set to be equal to the diameter of the rotating part 32. The embodiments of the present application do not make specific limitations in this regard.

[0085] In some other embodiments, the rotating member 30 may be made of an elastic material such as rubber. The positions of the rotating member 30 where a plurality of communication holes 321 are provided respectively protrude outward and abut against the inner wall of the receiving hole 21, and the sealing effect can also be achieved. The embodiments of the present application do not make specific limitations in this regard.

[0086] In this embodiment, the air supply joint 40 includes a fixed part 41 and a rotating part 42. The fixed part 41 is inserted into the air delivery channel 34. The rotating part 42 is connected to one end of the fixed part 41 away from the air delivery channel 34 and can rotate relative to the fixed part 41, so as to effectively reduce the probability of the air supply joint 40 getting knotted when the rotating member 30 rotates.

[0087] In this embodiment, the rotation driving mechanism 50 includes a transmission gear 51 and a rotation driving component 52. The transmission gear 51 is connected to the end of the rotating member 30 away from the air supply joint 40. The rotation driving component 52 is arranged on the substrate 11 of the base 10 and is connected to the transmission gear 51. The rotation driving component 52 is used to drive the rotating member 30 to rotate through the transmission gear 51. Since the accuracy of gear transmission is relatively high, it is beneficial to improve the accuracy of the rotation driving mechanism 50 in driving the rotating member 30 to rotate.

[0088] In this embodiment, on the side of each tooth 511 of the transmission gear 51 facing away from the rotating member 30, a contact protrusion 5111 is convexly provided. The rotation driving component 52 includes a moving driving member 521, a pushing member 522, a connecting member 523 and a pulling member 524. The moving driving member 521 is arranged on the connecting plate 13 of the base 10 and is located on one side of the dust removing member 20. The pushing member 522 is connected to the moving driving member 521 to approach or move away from the transmission gear 51 along the second direction under the drive of the moving driving member 521. A positioning groove 5221 is provided on the side of the pushing member 522 facing the transmission gear 51. One end of the connecting member 523 is connected to the pushing member 522. The pulling member 524 is arranged on the side of the transmission gear 51 away from the pushing member 522 and is connected to the other end of the connecting member 523. The side of the pulling member 524 facing the transmission gear 51 has a contact inclined surface 5241. The included angle between the contact inclined surface 5241 and the plane of the second direction and the first direction is an acute angle, and the contact inclined surface 5241 at least partially overlaps with the projection of one of the contact protrusions 5111 along the second direction.

[0089] Specifically, the pushing member 522 and the pulling member 524 are respectively disposed on opposite sides of the transmission gear 51 along the second direction. When the rotation driving assembly 52 drives the rotating member 30 to rotate through the transmission gear 51, first, the moving driving member 521 drives the pushing member 522 to approach the transmission gear 51 along the second direction. At this time, the positioning groove 5221 is located on the movement track of the abutting protrusion 5111. At this time, the pulling member 524 is driven by the connecting member 523 to move away from the transmission gear 51. The groove wall of the positioning groove 5221 abuts against an abutting protrusion 5111 and drives the transmission gear 51 to rotate, positioning the transmission gear 51 at the first preset angle and making the corresponding other abutting protrusion 5111 face the abutting inclined surface 5241. The pulling member 524 avoids the transmission gear 51 when the transmission gear 51 rotates. Then, the moving driving member 521 drives the pushing member 522 to move away from the transmission gear 51 along the second direction. At this time, the pulling member 524 is driven by the connecting member 523 to approach the transmission gear 51. The abutting inclined surface 5241 is located on the movement track of the abutting protrusion 5111, and the abutting inclined surface 5241 abuts against the corresponding other abutting protrusion 5111 and drives the transmission gear 51 to rotate by a second preset angle. The pushing member 522 avoids the transmission gear 51 when the transmission gear 51 rotates. In this way, the rotation driving assembly 52 has a simple structure and can improve the accuracy of driving the rotating member 30 to rotate through the transmission gear 51.

[0090] In this embodiment, the number of teeth P of the transmission gear 51 and the number of rotation positions N + 1 satisfy the following relational expression: P = K×(N + 1), where K is a positive integer greater than or equal to 1, and the sum of the first preset angle and the second preset angle is equal to 360° / P. For example, the number of both the air blowing holes 22 and the communication holes 321 is five, the number of rotation positions is six, and the angle between the axial sections of the rotating member 30 passing through two adjacent communication holes 321 is 60 degrees. When K is 1, the number of teeth P of the transmission gear 51 is six, and the sum of the first preset angle and the second preset angle is 60 degrees. Then, the moving driving member 521 drives the pushing member 522, the connecting member 523, and the pulling member 524 to perform a reciprocating motion once, and the transmission gear 51 can drive the rotating member 30 to rotate from one rotation position to an adjacent rotation position (i.e., the rotating member 30 rotates 60 degrees). When K is 2, the number of teeth P of the transmission gear 51 is twelve, and the sum of the first preset angle and the second preset angle is 30 degrees. Then, the moving driving member 521 drives the pushing member 522, the connecting member 523, and the pulling member 524 to perform two reciprocating motions, and the transmission gear 51 can drive the rotating member 30 to rotate from one rotation position to an adjacent rotation position (i.e., the rotating member 30 rotates 60 degrees).

[0091] In this embodiment, the shape of the positioning groove 5221 is V-shaped. The bottom of the positioning groove 5221 and the abutting protrusion 5111 can cooperate to position the transmission gear 51 when the transmission gear 51 rotates by a first preset angle, which is beneficial to improving the accuracy of the positioning groove 5221 to push the transmission gear 51 to rotate by the first preset angle.

[0092] In this embodiment, the moving driving member 521 is a telescopic cylinder. In some other embodiments, the moving driving member 521 can also be a linear slide table, an electric push rod or other linear driving members, and the embodiments of the present application do not make specific limitations thereto.

[0096] In summary, in the dust removal device 100 according to the embodiment of the present application, the rotating member 30 is rotatably arranged in the receiving hole 21 formed in the dust removal member 20. A plurality of air blowing holes 22 are formed in the peripheral side wall of the dust removal member 20 at intervals in the first direction and communicated with the receiving hole 21. A plurality of communication holes 321 are formed in the peripheral side wall of the rotating member 30 and arranged in the first direction and communicated with the air supply channel 34. The rotation driving mechanism 50 is provided to drive the rotation of the rotating member 30 and make the plurality of communication holes 321 communicate with the corresponding air blowing holes 22 in sequence. When the dust removal device 100 removes dust from the product being processed, the dust removal device 100 can be connected to only one air supply device. The rotation driving mechanism 50 drives the rotation of the rotating member 30 according to the specific processing position of the product, and makes a group of communication holes 321 corresponding to the specific processing position communicate with the air blowing holes 22. The dust removal gas with a larger wind force is discharged only through the connected group of communication holes 321 and air blowing holes 22 for dust removal, thereby improving the dust removal effect and reducing the dust removal cost.
