[0029] Please refer to Figure 1 and Figure 2 , and now the dust removal mechanism 10 provided by the embodiment of the present application will be described. The dust removal mechanism 10 provided by the embodiment of the present application includes a suction member 101 and an air delivery member 102. The suction member 101 is provided with a through hole 1013 with two open ends. One opening of the through hole 1013 is the first air inlet 103 of the suction member 101, and the other opening of the through hole 1013 is the first air outlet 104 of the suction member 101. The first air outlet 104 of the suction member 101 is used to connect to a negative pressure source; the air delivery member 102 is disposed at the edge of the first air inlet 103 of the suction member 101. The air delivery member 102 is provided with a communicated second air inlet 1031 and a second air outlet 1041. The second air inlet 1031 of the air delivery member 102 is used to connect to an air delivery source, and the second air outlet 1041 of the air delivery member 102 is disposed facing the side of the first air inlet 103 of the suction member 101.

[0030] In the dust removal mechanism 10 provided by the embodiment of the present application, the air delivery member 102 is used to guide the airflow output from the air delivery source to the side of the first air inlet 103 of the suction member 101, and the suction member 101 is used to absorb particulate impurities or dirt on the side of its first air inlet 103 under the action of a negative pressure source.

[0031] Among them, in the dust removal for a workpiece, the second air outlet 1041 of the air delivery member 102 and the first air inlet 103 of the suction member 101 are directed towards the part of the workpiece to be dusted. The airflow blown out by the air delivery source through the air delivery member 102 blows the particulate impurities or dirt on the workpiece away from the workpiece, so that the particulate impurities or dirt are in a free state on the side of the first air inlet 103 of the suction member 101. Under the action of the negative pressure source, the suction effect generated by the suction member 101 sucks the particulate impurities or dirt in this free state into the suction member 101 from its first air inlet 103 and discharges them from the first air outlet 104 of the suction member 101, preventing the particulate impurities or dirt from falling back onto the workpiece. Therefore, the cooperation of the air delivery member 102 and the suction member 101 of the dust removal mechanism 10 in the embodiment of the present application can effectively clean the particulate impurities or dirt on the workpiece.

[0032] Taking the second air outlet 1041 of the air delivery member 102 of the embodiment of the present application as an example, it is arranged inside the edge of the first air inlet 103 of the suction member 101, that is, the second air outlet 1041 of the air delivery member 102 is within the opening range of the first air inlet 103 of the suction member 101. It can also be understood that the suction station of the suction member 101 overlaps with the blowing station of the air delivery member 102. In this way, it can help the suction member 101 effectively absorb and discharge the particulate impurities or dirt blown up by the air delivery member 102. Of course, the air delivery member 102 can also be movably adjusted to adjust the orientation of the second air outlet 1041 of the air delivery member 102, so that the output airflow acts precisely on the position of the workpiece that needs dust removal.

[0033] Please refer to Figure 1 , further, the suction member 101 of the above embodiment may include a dust collection part 1011 and a dust guiding part 1012 connected along the direction of the through hole 1013. The through hole 1013 communicates the dust collection part 1011 and the dust guiding part 1012. The radial dimension of the through hole 1013 in the dust collection part 1011 is greater than or equal to the radial dimension of the through hole 1013 in the dust guiding part 1012; the opening of the through hole 1013 in the dust collection part 1011 is the first air inlet 103 of the suction member 101, and the opening of the through hole 1013 in the dust guiding part 1012 is the first air outlet 104 of the suction member 101.

[0034] It can be understood that the structure of the suction member 101 in the embodiments of the present application is formed by connecting the dust collection part 1011 and the dust guiding part 1012. The dust collection part 1011 and the dust guiding part 1012 can be integrally arranged or detachably connected. In the embodiments of the present application, taking the seamless connection of the dust collection part 1011 and the dust guiding part 1012 as an example, the through hole 1013 of the suction member 101 penetrates through the dust collection part 1011 and the dust guiding part 1012. The opening of the through hole 1013 in the dust collection part 1011 is the first air inlet 103 of the suction member 101, and the opening of the through hole 1013 in the dust guiding part 1012 is the first air outlet 104 of the suction member 101. That is, during the process of the suction member 101 sucking particulate impurities or dirt, etc., the particulate impurities or dirt, etc. are sucked from the dust collection part 1011 of the suction member 101 and then discharged through the dust guiding part 1012.

[0035] Among them, the radial dimension of the through hole 1013 in the dust collection part 1011 is set to be greater than or equal to the radial dimension of the through hole 1013 in the dust guiding part 1012. In the embodiments of the present application, taking the radial dimension of the through hole 1013 in the dust collection part 1011 being set to be greater than the radial dimension of the through hole 1013 in the dust guiding part 1012 as an example, so that the absorption range of the dust collection part 1011 is larger to prevent particulate impurities or dirt, etc. from being left out.

[0036] Furthermore, the radial dimension of the through hole 1013 in the dust collection part 1011 of the above embodiment gradually decreases along the direction of the through hole 1013 approaching the dust guiding part 1012.

[0037] It can be understood that along the direction of the through hole 1013 from the first air inlet 103 to the first air outlet 104, for the part of the through hole 1013 on the dust collection part 1011, the radial dimension of the through hole 1013 is set to gradually decrease, similar to a horn-shaped structure. With such a setting, not only can the absorption range of the dust collection part 1011 be larger, but also as the radial dimension of the through hole 1013 decreases, the air flow velocity of the suction effect is faster, that is, the greater the air pressure difference generated, so that the suction force on particulate impurities or dirt, etc. becomes stronger and stronger, which helps to effectively discharge the absorbed particulate impurities or dirt, etc.

[0038] Furthermore, the air delivery member 102 of the above embodiment surrounds the first air inlet 103 of the suction member 101 along the edge of the first air inlet 103 of the suction member 101, and the air delivery member 102 is symmetrically arranged with respect to the first air inlet 103 of the suction member 101.

[0039] The air delivery member 102 is disposed around the edge of the first air inlet 103 of the suction member 101 to surround the first air inlet 103 of the suction member 101. Specifically, the second air outlet 1041 of the air delivery member 102 is disposed around the edge of the first air inlet 103 of the suction member 101 to surround the first air inlet 103 of the suction member 101. When the dust-removing part of the workpiece to be dust-removed is located at the suction station of the suction member 101 and the air-blowing station of the air delivery member 102, it can be understood that the second air outlet 1041 of the air delivery member 102 surrounds the dust-removing part of the workpiece to be dust-removed, so that air flow can be output to the dust-removing part of the workpiece to be dust-removed in all directions, so as to blow off the particulate impurities or dirt, etc. on the dust-removing part of the workpiece to be dust-removed cleanly.

[0040] Specifically, taking the second air outlet 1041 of the air delivery member 102 being symmetrically arranged with respect to the first air inlet 103 of the suction member 101 as an example, when the relatively symmetric second air outlets 1041 of the air delivery member 102 output air flow and act on the workpiece, there is a certain counteracting effect, thus producing an effect of suspending the blown particulate impurities or dirt, etc. on the workpiece, which is helpful for the suction function of the suction member 101, and avoiding the situation that the particulate impurities or dirt, etc. are directly blown away from the workpiece farther due to the relatively disordered and staggered arrangement of the second air outlets 1041 of the air delivery member 102, or even far away from the first air inlet 103 of the suction member 101, resulting in some particulate impurities or dirt, etc. not being absorbed and discharged by the suction member 101 and falling on other positions in the processing environment.

[0041] Please refer to Figure 2 Furthermore, the dust removal mechanism 10 in any of the above embodiments may further include a mounting frame 106 and at least one set of clamping components 105. The suction member 101, the air delivery member 102 and the clamping components 105 are disposed on the mounting frame 106, and the clamping components 105 are disposed on the side close to the first air inlet 103 of the suction member 101; the second air outlet 1041 of the air delivery member 102 and the first air inlet 103 of the suction member 101 are respectively oriented towards the clamping station of the clamping components 105.

[0042] The clamping components 105 in the embodiments of the present application are used to clamp the workpiece to be dust-removed. The clamping station of the clamping components 105 is located in the regions where the second air outlet 1041 of the air delivery member 102 and the first air inlet 103 of the suction member 101 can respectively act. Specifically, the second air outlet 1041 of the air delivery member 102 and the first air inlet 103 of the suction member 101 are respectively oriented towards the clamping station of the clamping components 105, so as to be able to improve the efficient dust removal of the workpiece clamped and fixed by the clamping components 105. Of course, other fixing methods may also be adopted in the embodiments of the present application, and the corresponding structural components are used to fix the workpiece, as long as the fixing required for dust removal is satisfied.

[0043] Taking the example that the air extraction component, the air delivery component 102, and the clamping component 105 are respectively arranged to be relatively movably adjustable on the mounting frame 106, for the debugging and positioning during the installation process, so that the air extraction component, the air delivery component 102, and the clamping component 105 can be precisely coordinated for efficient dust removal. Specifically, the setting of the movable adjustment is not limited, and it can be the setting of using screws and strip holes, or the way of sliding adjustment, etc. The specific number of groups of the clamping component 105 in the embodiment of the present application can be determined according to needs, and it can be one group or multiple groups in cooperation. It should be noted that the air extraction component, the air delivery component 102, and the clamping component 105 can be directly connected to the mounting frame 106 respectively, or can be indirectly connected to the mounting frame 106 through an intermediate component.

[0044] Specifically, in the embodiment of the present application, the clamping station of the clamping component 105 is arranged corresponding to the central area of the first air inlet 103 of the suction component 101. It can be understood that the workpiece clamped and fixed by the clamping component 105 is located within the central area range of the first air inlet 103 of the suction component 101, so that the first air inlet 103 of the suction component 101 completely covers the corresponding surface of the workpiece, improving the dust removal efficiency.

[0045] Among them, the dust removal mechanism 10 may further include a driving component 107. The driving component 107 is arranged on the mounting frame 106. The clamping component 105 includes two clamping parts 1051 arranged oppositely. Between the two clamping parts 1051 is the clamping station of the clamping component 105; the driving component 107 is drivingly connected to the two clamping parts 1051, and the driving component 107 can drive the two clamping parts 1051 to move relatively closer or farther away.

[0046] The driving component 107 is used to drive the two clamping parts 1051 in the clamping component 105 to move relatively closer or farther away to clamp or release the workpiece. Specifically, the two clamping parts 1051 of each group of the clamping component 105 can be drivingly connected to the driving component 107, and the driving component 107 drives the two clamping parts 1051 to move synchronously; or one clamping part 1051 in each group of the clamping component 105 can be fixed, while the other clamping part 1051 is drivingly connected to the driving component 107, and the driving component 107 drives the corresponding clamping part 1051 to move. Among them, the driving component 107 can be a cylinder or a driving motor, as long as it meets the driving requirements. Specifically, taking the example that the dust removal mechanism 10 includes two groups of clamping components 105 in the present application, the driving component 107 is drivingly connected to each clamping part 1051 of the two groups of clamping components 105, and the driving component 107 drives the two groups of clamping components 105 to clamp or release synchronously. The two clamping parts 1051 of each group of the clamping component 105 move synchronously. The movable setting of the two clamping parts 1051 of each group of the clamping component 105 can make the clamping stroke larger and can be used to clamp workpieces with a larger range of clamping action sizes; and the cooperation of the two groups of clamping components 105 can improve the clamping stability.

[0047] Specifically, the dust removal mechanism 10 may further include two connecting members 108. The two connecting members 108 are respectively movably disposed on the mounting bracket 106 along the clamping direction of the two clamping members 1051. The driving member 107 is drivingly connected to the two connecting members 108. One clamping member 1051 of each set of clamping assemblies 105 is movably adjustable and disposed on one connecting member 108. The driving member 107 drives the two connecting members 108 to move so as to drive the corresponding clamping members 1051 to move synchronously.

[0048] In the embodiment of the present application, the connecting member 108 is used as an intermediate member for drivingly connecting the driving member 107 and the clamping member 1051. That is, one clamping member 1051 of each set of clamping assemblies 105 is connected to one connecting member 108, and the other clamping member 1051 is connected to the other connecting member 108. The driving member 107 drives the two connecting members 108 to move relatively closer or farther away, thereby synchronously controlling the two sets of clamping assemblies 105. Among them, taking the connection mode between the clamping member 1051 and the connecting member 108 as a movably adjustable connection mode as an example, so as to install and debug the clamping member 1051 to the required appropriate position. The specific movably adjustable connection mode can be a screw cooperating with a strip-shaped hole, or other movable adjustable modes, as long as the conditions are met.

[0049] Please refer to Figure 2 and Figure 3 Furthermore, define the relative setting direction of the two clamping members 1051 as the first direction, denoted as X. The first direction is parallel to the horizontal plane. Define the second direction perpendicular to the horizontal plane, denoted as Y. The clamping member 1051 is provided with two limiting blocks 1052 opposite to each other along the second direction. The two limiting blocks 1052 protrude along the first direction toward the clamping station side of the clamping assembly 105. The limiting block 1052 closer to the upper end of the clamping member 1051 along the second direction is elastically arranged along the first direction.

[0050] It can be understood that the second direction is the vertical direction. The two limiting blocks 1052 provided on the clamping member 1051 are arranged at intervals along the vertical direction. Here, the upper limiting block 1052 and the lower limiting block 1052 are used to describe the two limiting blocks 1052. Both limiting blocks protrude along the first direction toward the clamping station side of the clamping assembly 105. So that when clamping a workpiece, the lower limiting block 1052 can be used to support the workpiece, and the upper limiting block 1052 can be used to press the workpiece. The upper limiting block 1052 and the lower limiting block 1052 cooperate to achieve the positioning effect of the workpiece in the vertical direction. At the same time, the clamping effect of the clamping assembly 105 can be used to position the workpiece in the horizontal direction.

[0051] Among them, the upper limiting block 1052 is elastically arranged along the first direction. When used to clamp the workpiece along the first direction, it can avoid hard collision with the workpiece and damage the workpiece. Of course, when used for different workpieces, the function of the upper limiting block 1052 is also different, but being elastically arranged along the first direction can prevent hard contact with the workpiece and damage the workpiece. The specific elastic arrangement can be to elastically connect the upper limiting block 1052 with an elastic member such as a spring.

[0052] It should be noted that in the embodiment of the present application, the upper limiting block 1052 and / or the lower limiting block 1052 are / is movably adjustable along the vertical direction as an example, so as to be able to debug the vertical use range of the clamping member 1051 and improve the use accuracy and versatility of the clamping member 1051.

[0053] Please refer to Figure 4 , the embodiment of the present application also provides a processing device 20, including a transportation mechanism 201, a laser welding mechanism 202, and the dust removal mechanism 10 in any of the above embodiments. The transportation mechanism 201 is used to transport the workpiece, and the transportation mechanism 201 can transport the workpiece to the dust removal mechanism 10 for dust removal and transport the workpiece to the laser welding mechanism 202 for welding.

[0054] The processing device 20 of the embodiment of the present application, because it includes the dust removal mechanism 10 in any of the above embodiments, has the beneficial effects brought by the dust removal mechanism 10 in any of the above embodiments, which will not be elaborated here. Among them, the transportation mechanism 201 is used to transport the workpiece to the clamping station of the clamping assembly 105, and then the clamping assembly 105 clamps the workpiece. The air delivery member 102 and the suction member 101 of the dust removal mechanism 10 cooperate to dust the workpiece that has been clamped and fixed. After dust removal, the clamping assembly 105 docks with the transportation mechanism 201 again for the workpiece, and the transportation mechanism 201 transports the dust-removed workpiece to the laser welding mechanism 202, and the laser welding mechanism 202 is used to weld and process the dust-removed workpiece.

[0055] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
