Utility Model Content

[0005] In view of this, this utility model proposes a turret flying welding dust removal mechanism for cylindrical batteries, which can be used in conjunction with turret flying welding and can provide a greater flow rate and negative pressure effect, effectively removing welding slag and welding fumes, reducing the pollution of the battery by welding slag and fumes, improving the cleanliness and electrical performance of the battery, thereby extending the battery's service life.

[0006] The technical solution of this utility model is achieved as follows: This utility model provides a turret-type flying welding dust removal mechanism for cylindrical batteries, including a housing, a first air duct, and a dust suction window, wherein...

[0007] The shell is relatively movable on one side of the turret flying welding station, and the interior of the shell is hollow. Both sides of the shell in the vertical direction have hollow windows to provide clearance space for laser welding.

[0008] The first air duct is located on the shell, and the air outlet of the first air duct is set parallel to the turret flight welding station.

[0009] The dust extraction window is located on the housing and is positioned opposite to the first air duct. The first air duct blows horizontally, blowing the welding slag into the dust extraction window and out of the housing.

[0010] Based on the above technical solutions, preferably, the shell is arc-shaped, and the axis of the shell is at the same position as the axis of the turret flying welding equipment.

[0011] Based on the above technical solutions, preferably, the hollow windows on both sides are arc-shaped and are at the same position on the vertical projection plane, and the hollow window below is set on the same horizontal plane as the turret flight welding station.

[0012] Based on the above technical solutions, preferably, a first protrusion is provided on the side of the housing away from the dust extraction window, a first air duct is opened in the first protrusion and is connected to the interior of the housing, and a plurality of first air inlets are opened on the first protrusion and are connected to the first air duct. The plurality of first air inlets are connected to the air outlet of the external air supply equipment, and the air outlet of the external air supply equipment is sent into the first air duct to blow air horizontally to the turret welding station.

[0013] Based on the above technical solutions, preferably, the number of the first protrusions is at least two, and the at least two first protrusions are arranged at intervals along the vertical direction of the housing, and the width of the first air duct matches the width of the dust extraction window.

[0014] Based on the above technical solutions, preferably, it also includes at least two negative pressure suction pipes, which are respectively arranged on both sides of the longitudinal direction of the shell, and the negative pressure suction pipes and the suction window are connected to the suction end of the external suction equipment for suctioning welding slag in the longitudinal direction.

[0015] Based on the above technical solutions, preferably, the first air duct below is on the same horizontal plane as the negative pressure suction pipe and the suction window.

[0016] Based on the above technical solution, preferably, a second protrusion is provided on the side of the shell away from the turret flight welding station, and the second protrusion is located at the edge of the upper hollow window.

[0019] The dust removal mechanism for turret-type flying welding of cylindrical batteries of this invention has the following advantages over the prior art:

[0020] (1) The hollowed-out windows on both sides of the shell provide space for laser welding, ensuring the normal progress of the welding process. At the same time, the horizontal airflow generated by the first air duct and the dust extraction window can provide a greater flow rate and negative pressure effect through the relative setting of the first air duct and the dust extraction window. This blows the welding slag and dust generated during the welding process to the dust extraction window, reducing the pollution of the battery by the welding slag and dust, improving the cleanliness and electrical performance of the battery, and thus extending the battery's service life.

[0023] (4) By opening the second air duct and tilting it towards the inside of the shell, the oblique air blowing can more effectively capture and disperse the welding slag and dust generated during the welding process, preventing them from escaping from the hollow window above the shell, thereby improving the dust removal efficiency.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] like Figure 1-4 As shown, this utility model discloses a dust removal mechanism for a cylindrical battery turret flying welder, characterized in that it includes: a housing 1, a first air duct 2, and a dust extraction window 3. The housing 1 is movably disposed on one side of the turret flying welder station, and the interior of the housing 1 is hollow. Hollow windows 100 are provided on both sides of the housing 1 in the vertical direction to provide clearance space for laser welding. The first air duct 2 is opened on the housing 1, and the air outlet of the first air duct 2 is arranged parallel to the turret flying welder station. The dust extraction window 3 is opened on the housing 1 and is arranged opposite to the first air duct 2. The first air duct 2 blows horizontally, blowing the welding slag into the dust extraction window 3 and out of the housing 1.

[0031] It should be noted that the perforated windows 100 on both sides of the housing 1 provide clearance for laser welding, ensuring the normal progress of the welding process. At the same time, through the relative arrangement of the first air duct 2 and the dust extraction window 3, the horizontal airflow generated by the first air duct 2 blows the welding slag and fumes generated during the welding process to the dust extraction window 3, reducing the pollution of the battery by welding slag and fumes, improving the cleanliness and electrical performance of the battery, and thus extending the battery's service life.

[0032] In this embodiment, the housing 1 is arc-shaped, and the axis of the housing 1 is at the same position as the axis of the turret flying welding equipment.

[0033] It should be noted that the housing 1 is arc-shaped, and the axis of the housing 1 is at the same position as the axis of the turret flying welding equipment. This ensures that the housing 1 can maintain a precise relative position with the welding equipment during the rotation of the turret flying welding equipment, thereby improving the accuracy and stability of dust removal.

[0034] Specifically, a circular track is set along the turret flying welding equipment, and the housing 1 is relatively slidably set on the circular track, so that the housing 1 can rotate along the center of the turret flying welding equipment and pass through each welding station of the turret flying welding equipment in sequence.

[0035] In this embodiment, the hollow windows 100 on both sides are arc-shaped and are at the same position on the vertical projection plane, and the hollow window 100 below is set on the same horizontal plane as the turret flight welding station.

[0036] In this embodiment, a first protrusion 11 is provided on the side of the housing 1 away from the dust extraction window 3. A first air duct 2 is opened in the first protrusion 11 and is connected to the interior of the housing 1. A plurality of first air inlets 110 are provided on the first protrusion 11 and are connected to the first air duct 2. The plurality of first air inlets 110 are all connected to the air outlet of the external air supply equipment. The air outlet of the external air supply equipment is sent into the first air duct 2 to blow air horizontally to the turret welding station.

[0037] It should be noted that the first protrusion 11 provides space for the first air duct 2 without interfering with the welding operation and dust collection function. Multiple first air inlets 110 provide access points for external air supply equipment, allowing air to smoothly enter the first air duct 2. Horizontal air blowing blows the welding slag and fumes generated during the welding process to the direction of the dust collection window 3, where they are effectively collected and treated, improving dust removal efficiency and reducing the amount of welding slag and fumes escaping.

[0038] In this embodiment, there are at least two first protrusions 11, and at least two first protrusions 11 are arranged at intervals along the vertical direction of the housing 1, and the width of the first air duct 2 matches the width of the dust extraction window 3.

[0039] It should be noted that at least two first protrusions 11 are distributed vertically, which enhances the dust removal effect. The cleanliness of the welding area is improved by the simultaneous action of multiple first air ducts 2. Furthermore, the horizontal airflow generated by the first air ducts 2 blows the welding slag and fumes to the dust collection window 3, which is responsible for discharging these pollutants outside the housing 1. The matching width makes the process more efficient and smooth.

[0040] This embodiment also includes at least two negative pressure suction pipes 4, which are respectively arranged on both sides of the longitudinal direction of the housing 1. The negative pressure suction pipes 4 and the suction window 3 are connected to the suction end of the external suction device for suctioning welding slag in the longitudinal direction.

[0041] It should be noted that by setting negative pressure dust suction pipes 4 on both sides of the longitudinal direction of the shell 1, the welding area can be fully covered, reducing the escape of welding slag and fumes and improving the dust removal effect.

[0042] In this embodiment, the first air duct 2 below, the negative pressure suction pipe 4, and the suction window 3 are on the same horizontal plane.

[0043] It should be noted that the first air duct 2, the negative pressure suction pipe 4, and the suction window 3 are on the same horizontal plane, which reduces the turning and resistance of the airflow during transmission, reduces the possibility of airflow interference, and allows the horizontal airflow blown out from the first air duct 2 to more directly and effectively blow the welding slag and dust to the negative pressure suction pipe 4 and the suction window 3, thereby improving the dust removal effect, reducing the pollution of the battery by welding slag and dust, and improving the cleanliness and electrical performance of the battery.

[0044] In this embodiment, a second protrusion 12 is provided on the side of the housing 1 away from the turret flight welding station, and the second protrusion 12 is located at the edge of the upper hollow window 100. A second air duct 5 is opened in the second protrusion 12 and is inclined towards the inside of the housing 1. A plurality of second air inlets 120 are opened on the outside of the second protrusion 12. The plurality of second air inlets 120 are all connected to the air outlet of the external air supply equipment. The air outlet of the external air supply equipment is sent into the second air duct 5 and blows air obliquely into the housing 1.

[0045] It should be noted that the second protrusion 12 is located on the side of the housing 1 away from the turret flight welding station and at the edge of the upper hollow window 100. This does not affect the welding operation and can effectively provide installation space for the second air duct 5. The second protrusion 12 is provided with multiple second air inlets 120, which provide access points for external air supply equipment, allowing air to enter the air duct smoothly. The second air duct 5 is opened inside the second protrusion 12 and is inclined towards the inside of the housing 1. The oblique airflow can more effectively capture and disperse the welding slag and dust generated during the welding process, preventing them from escaping from the upper hollow window 100 of the housing 1, thereby improving the dust removal efficiency.

[0046] In this embodiment, the second air duct 5 is tilted downward at an angle of 10-30°, specifically, the second air duct 5 is tilted downward at an angle of 20°.

[0047] In this embodiment, the distance from the inner side of the hollow window 100 to the turret flight welding station is 2-4 mm.

[0048] It should be noted that the distance between the perforated window 100 and the welding station is controlled at 2-4mm, achieving precise avoidance of the laser welding path while ensuring efficient coordination between the dust removal airflow and the welding area. This balances the risk of mechanical interference with the requirement for dust removal efficiency, allowing the airflow to directly cover the welding slag and fumes generated during welding.

[0049] Working principle:

[0050] During the welding process, air is supplied to the first air inlet 110 and the second air inlet 120 by external air supply equipment, and flows into the first air duct 2 and the second air duct 5 respectively. The first air duct 2 forms a horizontal airflow, and the second air duct 5 forms an oblique airflow. The horizontal airflow blows the welding slag and dust generated during welding to the direction of the dust collection window 3. At the same time, the oblique airflow blows air into the inside of the shell 1. The oblique airflow covers the welding area, captures the escaped light dust, prevents it from escaping from the shell 1, and blows it towards the direction of the dust collection window 3. The external dust collection equipment simultaneously sucks in the negative pressure dust collection pipe 4 and the dust collection window 3 to discharge the welding slag and dust from the shell 1, thereby achieving all-round dust removal.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
