Description

Technical Field

[0001] The present application relates to the field of welding technology, and in particular to a welding device and battery production equipment. Background Art

[0002] During the welding process, a clamping component is usually used to clamp the object to be welded, and the welding equipment welds the object to be welded clamped by the clamping component. This causes the welding ash generated during the welding process to inevitably fall onto the clamping component.

[0003] In order to prevent excessive welding ash from accumulating on the clamping parts and affecting the quality of the object to be welded, workers usually manually clean the welding ash accumulated on the clamping parts every once in a while. However, manual cleaning will affect the progress of the welding process and further affect the production capacity of the object to be welded. Therefore, how to automatically clean the welding ash on the clamping parts has become an urgent problem to be solved. Utility Model Content

[0004] The present application aims to solve at least one of the technical problems existing in the background technology. To this end, one purpose of the present application is to provide a welding device and a battery production equipment to solve the problem of how to automatically clean the welding ash on the clamping parts in the related art.

[0005] An embodiment of the first aspect of the present application provides a welding device, comprising: a clamping component for clamping an object to be welded; a welding assembly, configured to weld the object to be welded clamped by the clamping component according to a preset welding trajectory; a dust removal component, configured to: move to the clamping component and remove dust from the clamping component during a period when the welding assembly is not welding, and move away from the clamping component after the dust removal is completed; and a driving component, configured to drive the dust removal component to move.

[0006] In the technical solution of the embodiment of the present application, the dust removal component is moved to the clamping component by the driving component to remove dust from the clamping component only when dust removal is required, and the dust removal component is removed from the clamping component after the dust removal is completed. In this way, the dust removal component will not affect the welding of the welding assembly to the object to be welded, and can realize automatic dust removal of the clamping component, while solving the problem of affecting the quality of the object to be welded due to excessive welding ash accumulated on the clamping component, and reducing the impact of the dust removal step of the dust removal component on the production capacity of the object to be welded.

[0007] In some embodiments, the clamping component is used to define a clamping position for accommodating the object to be welded, and the welding assembly is configured to be located above the clamping position to weld the object to be welded. In this way, the welding assembly is directly opposite to the object to be welded, and the object to be welded clamped by the clamping component can be welded well. And because the dust removal component is only moved to the clamping component when the welding component is not welding, the dust removal of the clamping component by the dust removal component will not affect the welding process of the welding assembly located above the clamping position on the object to be welded, thereby reducing the impact of the dust removal step of the dust removal component on the production capacity of the object to be welded.

[0008] In some embodiments, the dust removal component is configured to be able to move to the surface of the clamping component close to the welding assembly to remove dust from the clamping component. In this way, the dust removal component can be in close contact with the clamping component surface, thereby being able to more efficiently remove the welding ash on the clamping component surface.

[0009] In some embodiments, the dust removal component is configured to move along the welding track to remove dust from the clamping component. Since the welding assembly moves along the welding track during welding, there is more welding ash on the welding track. Therefore, the dust removal component moves along the welding track to remove dust from the clamping component, which can remove more welding ash on the welding track in a targeted manner.

[0010] In some embodiments, when the clamping component is used to define the clamping position, the orthographic projection of the welding track on the clamping position coincides with the periphery of the clamping position. In other words, the welding ash generated by the welding assembly during the welding process falls more on the periphery of the clamping position, and then the welding ash on the surface of the clamping component at the periphery of the clamping position is distributed along the welding track. The dust removal component removes dust from the clamping component along the welding track, which can remove as much welding ash distributed on the surface of the clamping component as possible, thereby improving the dust removal efficiency of the clamping component.

[0011] In some embodiments, the driving component includes: a first sub-driving component configured to drive the dust removal component to move along the welding track; a second sub-driving component configured to drive the dust removal component to move to the clamping component, and after the dust removal is completed, drive the dust removal component to move away from the clamping component. The first sub-driving component is used to drive the movement of the dust removal component during the dust removal process, and the second sub-driving component is used to drive the movement of the dust removal component before and after the dust removal, so as to accurately control the travel of the dust removal component, and enable the dust removal component to automatically remove dust from the clamping component without affecting the welding of the welding assembly to the object to be welded.

[0012] In some embodiments, the first sub-driving component is further configured to: drive the welding assembly to move along the welding track. That is, the welding assembly and the dust removal component share the first sub-driving component. On the one hand, there is no need to set up an additional driving component for driving the dust removal component to move along the welding track, which saves costs. On the other hand, the moving track of the dust removal component is highly overlapped with the moving track of the welding assembly, which improves the reliability of the dust removal component moving along the welding track.

[0013] In some embodiments, the welding assembly includes: a first mounting seat; a welding head disposed on the first mounting seat, the welding head being used to weld the object to be welded, wherein the dust removal component is disposed on the first mounting seat. In other words, the dust removal component and the welding head are disposed on the same first mounting seat, so that the first sub-driving component can drive both the dust removal component and the welding head to move, and the moving tracks of the dust removal component and the welding head are highly overlapped.

[0014] In some embodiments, the welding device further includes: a first mounting structure disposed on the first mounting seat, the dust removal component is rotatably mounted on the first mounting structure via a rotating shaft, and the second sub-driving component is configured to: drive the dust removal component to rotate around the rotating shaft to the clamping component, and after the dust removal is completed, drive the dust removal component to move away from the clamping component. In this way, through the second sub-driving component, the dust removal component is rotated to the clamping component only when dust removal is required, and the dust removal component and the welding assembly can share the first driving component, so that the first sub-driving component can drive the dust removal component to move according to the welding trajectory.

[0015] In some embodiments, the second sub-driving component is mounted on the first mounting seat. That is, the second sub-driving component, the welding head and the dust removal component are all mounted on the first mounting seat, so that the first sub-driving component drives the dust removal component to move along the welding track while driving the second sub-driving component to move along the welding track, thereby maintaining the relative position between the second sub-driving component and the dust removal component unchanged, avoiding the problem of the dust removal component moving away from the clamping component during the dust removal process.

[0016] In some embodiments, the dust removal component includes: a second mounting seat; a dust removal head mounted on the second mounting seat, the dust removal head is used to contact the surface of the clamping component, the dust removal head has a first hollow cavity, and the first hollow cavity is used to define a first dust removal port of the dust removal head. In this way, the dust removal airflow can be transported through the first hollow cavity and efficiently remove the welding ash on the surface of the clamping component at a close distance through the first dust removal port.

[0017] In some embodiments, the dust removal head includes: a first mounting portion, fixed to a second mounting seat; a cleaning portion connected to the first mounting portion, a first hollow cavity axially extending through the first mounting portion and the cleaning portion, the cleaning portion being used to contact the surface of the clamping component, and the surface of the cleaning portion being used to contact the clamping component is a flexible surface. In this way, the dust removal head can be stably connected to the second mounting seat through the first mounting portion, and the cleaning portion can contact the surface of the clamping component during movement to clean the welding ash on the surface of the clamping component, thereby strengthening the removal of welding ash attached to the surface of the clamping component, and the cleaning portion contacts the clamping component through a flexible surface, thereby reducing the damage caused to the surface of the clamping component by the cleaning portion during movement.

[0018] In some embodiments, the cleaning part is a brush. The brush is relatively soft and can reduce scratches and damage to the surface of the clamping component during the dust removal process. In addition, when the brush contacts the surface of the clamping component, a certain friction is generated between the brush and the surface of the clamping component, which can shovel up the welding ash firmly attached to the surface of the clamping component, and then remove the shoveled welding ash through the first dust removal port, thereby achieving efficient dust removal on the surface of the clamping component.

[0019] In some embodiments, the dust removal component further includes: a collector, which is mounted on the second mounting seat and has a second hollow cavity, the dust removal head is mounted in the second hollow cavity, and the second hollow cavity is connected to the first hollow cavity, and the collector is configured to form a negative pressure in the second hollow cavity during dust removal by the dust removal component. The collector has the function of concentrating the airflow, and the second hollow cavity in the collector forms a negative pressure, so that the first hollow cavity connected to the second hollow cavity also forms a negative pressure, so that the first hollow cavity absorbs the welding ash on the surface of the clamping component through the first dust removal port.

[0020] In some embodiments, the collector includes: a first portion, a second mounting portion, and a second portion connected in sequence, a second hollow cavity axially penetrates the first portion, the second mounting portion, and the second portion, a dust removal head is mounted on the inner wall of the second mounting portion along the axial direction of the second hollow cavity, and the second hollow cavity in the second portion also surrounds a portion of the outer circumference of the dust removal head. In this way, the second hollow cavity in the second portion surrounding a portion of the outer circumference of the dust removal head can also absorb welding ash on the surface of the clamping component, so that the welding ash is sucked away from the gap between the second hollow cavity and the dust removal head, thereby further enhancing the dust removal efficiency of the dust removal component on the clamping component.

[0021] In some embodiments, the inner diameter of the first portion gradually increases in the direction from the second portion to the first portion, so as to enhance the effect of the concentrated airflow of the collecting cover and improve the cleaning power of the dust removal head on the surface of the clamping component.

[0022] In some embodiments, the second mounting portion further includes: a plurality of third hollow cavities spaced apart along the outer periphery of the dust removal head, the third hollow cavity penetrating the second mounting portion along the axial direction of the second hollow cavity, and communicating with the second hollow cavities of the first portion and the second portion. In this way, the first hollow cavity forms a dust removal channel located inside the dust removal head, and the third hollow cavity forms a dust removal channel located outside the dust removal head. Through the plurality of dust removal channels, the welding ash of the clamping component is adsorbed, further enhancing the dust removal efficiency of the dust removal component on the clamping component.

[0023] In some embodiments, the bottom of the dust removal head protrudes from the bottom of the second hollow cavity, and the bottom of the dust removal head is used to contact the surface of the clamping component. The bottom of the second hollow cavity is the bottom of the current collecting cover, so that only the bottom of the dust removal head contacts the surface of the clamping component, reducing the probability of the bottom of the current collecting cover touching the surface of the clamping component, thereby reducing the scratches or damages of the dust removal component to the surface of the clamping component.

[0024] In some embodiments, the bottom of the dust removal head protrudes from the bottom of the second hollow cavity by 2 mm to 7 mm. Within this range, the dust removal component can have a better dust removal effect on the clamping component and reduce the probability of the bottom of the collector touching the surface of the clamping component.

[0025] In some embodiments, the dust removal component further includes: a vibration component mounted on the second mounting seat, the vibration component being configured to control the dust removal head to vibrate during dust removal by the dust removal component. The vibration component can vibrate the welding ash attached to the surface of the clamping component, thereby improving the adsorption efficiency of the dust removal head on the welding ash, and thereby improving the dust removal efficiency of the dust removal component on the clamping component.

[0026] In some embodiments, when the dust removal component includes a current collecting cover, the second mounting seat includes a mounting cavity, the mounting cavity includes a first side wall and a second side wall opposite to each other, the vibration component is located in the mounting cavity and fixed to the first side wall, and the current collecting cover is located outside the mounting cavity and fixed to the second side wall. In other words, the vibration component and the current collecting cover are respectively mounted on different side walls of the mounting cavity, so that the vibration amplitude transmitted from the vibration component to the current collecting cover is not too large, so that the current collecting cover is firmly connected to the outer wall of the mounting cavity.

[0027] In some embodiments, when the dust removal head includes the first mounting portion, the dust removal head is fixed in the current collecting cover by a spring locking pin. The spring locking pin has a certain shock absorbing effect, which can solve the problem of the dust removal head becoming loose due to excessively strong vibration, thereby reducing the risk of the dust removal head falling off from the current collecting cover. In other words, the dust removal head can be locked in the current collecting cover even under strong vibration, which is conducive to vibration conduction.

[0028] In some embodiments, when the welding assembly includes a first mounting seat, the dust removal component further includes a buffer component, and the mounting cavity is mounted on the first mounting seat through the buffer component. In this way, the vibration of the vibration component in the mounting cavity can be reduced from being transmitted to other structures of the first mounting seat.

[0029] In some embodiments, when the welding assembly includes a first mounting seat, and the welding head and the dust removal component of the welding assembly are both disposed on the first mounting seat, the welding assembly further includes a dust removal hood disposed on the first mounting seat, the dust removal hood has a second dust removal port, and the dust removal component is configured to move to the first hollow cavity of the dust removal head to face the second dust removal port, so that the dust removal hood removes dust from the clamping component via the second dust removal port and the first dust removal port of the first hollow cavity. The dust removal hood can be a component in the welding assembly used to remove dust from the welding head. Using the existing dust removal hood in the welding assembly as an exhaust device for the dust removal head can save costs and reduce the space occupied by the welding device.

[0030] In some embodiments, the dust hood is provided on the outer peripheral surface of the welding head. In this way, the dust hood can not only remove the welding ash generated by the welding head during the welding process, but also can be used to remove dust from the clamping component, so that there is no need to additionally set up an exhaust device for forming a negative pressure in the dust removal head of the dust removal component, thereby saving costs. In addition, because the dust hood is provided on the outer peripheral surface of the welding head, the movement trajectory of the dust removal component is highly overlapped with the movement trajectory of the welding head and the dust hood, so that during the movement of the dust removal component, the dust hood can accurately face the first hollow cavity of the dust removal head, thereby improving the reliability of the dust removal component in removing dust from the clamping component.

[0031] In some embodiments, when the dust removal component includes a flow collecting cover, the dust removal component is configured to move to the second hollow cavity of the flow collecting cover to face the second dust removal port. In this way, the flow collecting cover can collect the airflow transmitted from the second dust removal port and guide the airflow to the first dust removal port of the dust removal head, which is conducive to improving the dust removal strength of the dust removal head on the clamping component.

[0032] In some embodiments, when the collector includes a first portion, a second mounting portion, and a second portion, the second dust removal port is directly opposite to the first portion, and the orthographic projection of the second dust removal port on the surface of the first portion coincides with the opening of the first portion toward the second dust removal port. In this way, the collector can further enhance the concentration effect of the airflow transmitted at the second dust removal port, guide more of the airflow transmitted at the second dust removal port to the first dust removal port, and further enhance the dust removal strength of the dust removal head on the clamping component.

[0033] The second aspect of the present application provides a battery production device, which includes the welding device in the above embodiment, and the welding device is configured to weld the battery. Since the welding device can realize automatic dust removal of the clamping component without affecting the welding process of the welding assembly, in the process of using the battery production equipment to produce batteries, the welding ash on the clamping component can be removed without stopping the machine, and the welding ash on the clamping component can be kept less, reducing the impact of the welding ash on the quality of the battery, and at the same time, maintaining a high production capacity of the battery.

[0034] In some embodiments, the welding device is configured to weld the end cap and the shell of the battery. In this way, the dust removal component in the welding device can remove the welding ash generated during the welding process of the end cap and the shell of the battery, thereby improving the problem that the subsequent welding process of the end cap and the shell of the battery is affected by excessive welding ash on the clamping component, so that the produced battery has a higher quality.

[0035] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0080] A large amount of welding ash is generated during the welding process, and the welding ash will fall onto the surface of the clamping component used to clamp the object to be welded during the welding process. After the clamping component has been used for a period of time, a lot of welding ash will accumulate on the clamping component. In this way, when the clamping component clamps the object to be welded, the welding ash on the clamping component will also fall onto the surface of the object to be welded, affecting the quality of the object to be welded.

[0081] In the related art, in order to prevent excessive welding ash from accumulating on the clamping parts and affecting the quality of the object to be welded, the staff will manually clean the welding ash on the clamping parts after each welding process. For example, the clamping parts are cleaned for 3 to 5 minutes after every two hours of welding process.

[0082] During the manual cleaning of welding ash, in order to ensure the safety of personnel, the welding equipment needs to be shut down, and all components in the welding equipment will be reset due to the shutdown. When the welding equipment is restarted, all components in the welding equipment need to be started again to put all components in place. In addition, it takes a long time to manually clean the welding ash, resulting in the welding equipment being shut down for too long, and it takes a long time to restart, which affects the welding process of the welding equipment on the object to be welded, and further affects the production capacity of the object to be welded.

[0083] In addition, manually cleaning welding ash is likely to cause problems such as untimely or incomplete cleaning of the clamping parts, which can easily cause welding defects in the object to be welded, thereby affecting the quality of the object to be welded.

[0084] Based on the above considerations, in order to solve the problem that the welding ash on the clamping component cannot be automatically cleaned, which affects the production capacity and quality of the object to be welded, a welding device is designed. By setting a dust removal component and a driving component, the dust removal component is moved to the clamping component by the driving component only when dust removal is needed to remove dust from the clamping component. After the dust removal is completed, the dust removal component is removed from the clamping component. In this way, during the welding of the welding assembly, the dust removal component will not affect the welding process of the object to be welded, and the automatic dust removal of the clamping component can be achieved. While solving the problem that the quality of the object to be welded is affected by excessive welding ash accumulated on the clamping component, the dust removal step of the dust removal component reduces the impact on the production capacity of the object to be welded.

[0085] The welding device disclosed in the embodiment of the present application can be used for, but not limited to, welding of battery cells / batteries, and the battery cells / batteries can be used in, but not limited to, electrical devices such as vehicles, ships, or aircraft.

[0089] In the battery 100, there may be multiple battery cells 20, and the multiple battery cells 20 may be connected in series, in parallel, or in mixed connection, where mixed connection means that the multiple battery cells 20 are connected in series and in parallel. The battery 100 may also include other structures, for example, the battery 100 may also include a busbar component for realizing electrical connection between the multiple battery cells 20.

[0090] Each battery cell 20 may be a secondary battery or a primary battery, or a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 may be cylindrical, flat, rectangular, or in other shapes.

A battery cell 20 refers to the smallest unit that constitutes a battery. Figure 2 The battery cell 20 includes an end cover 21, a shell 22, a battery cell assembly 23 and other functional components.

The material of the end cap 21 may also be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc. In some embodiments, an insulating member may also be provided on the inner side of the end cap 21, and the insulating member may be used to isolate the electrical connection components in the housing 22 from the end cap 21 to reduce the risk of short circuit. Exemplarily, the insulating member may be plastic, rubber, etc.

[0094] The shell 22 is a component used to cooperate with the end cover 21 to form the internal environment of the battery cell 20, wherein the formed internal environment can be used to accommodate the battery cell assembly 23, electrolyte and other components. The shell 22 and the end cover 21 can be independent components, and an opening can be set on the shell 22, and the internal environment of the battery cell 20 is formed by covering the opening with the end cover 21. The end cover 21 and the shell 22 can be connected by welding. For example, the edge of the end cover can be welded to the edge of the opening of the shell so that the end cover covers the opening of the shell.

[0095] The housing 22 may be in various shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, a hexagonal prism, etc. Specifically, the shape of the housing 22 may be determined according to the specific shape and size of the battery cell assembly 23. The housing 22 may be made of various materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc.

[0096] The cell assembly 23 is a component where electrochemical reactions occur in the battery cell 20. The housing 22 may contain one or more cell assemblies 23. The cell assembly 23 is mainly formed by winding or stacking a positive electrode sheet and a negative electrode sheet, and a separator is usually provided between the positive electrode sheet and the negative electrode sheet.

[0097] refer to Figures 3 to 5 , Figure 3 A schematic diagram of the three-dimensional structure of a dust removal device in some embodiments of the present application; Figure 4 This is a schematic diagram of the main structure of the dust removal device of some embodiments of the present application; Figure 5 This is a schematic side view of the structure of the dust removal device of some embodiments of the present application.

[0098] An embodiment of the present application provides a welding device, including: a clamping component 101, used to clamp an object to be welded; a welding assembly 102, configured to be able to weld the object to be welded clamped by the clamping component 101 according to a preset welding trajectory; a dust removal component 103, configured to: be able to move to the clamping component 101 and remove dust from the clamping component 101 during a period when the welding assembly 102 is not welding, and move away from the clamping component 101 after the dust removal is completed; and a driving component 104, configured to be able to drive the dust removal component 103 to move.

[0099] The welding track refers to the welding position on the object to be welded when the welding assembly 102 welds the object to be welded. For example, in the case of welding the end cap and the shell of a battery, the end cap and the opening of the shell are welded, and the welding track can be the junction where the end cap and the opening of the shell are welded. Specifically, it can be the periphery of the opening of the shell.

[0100] The welding machine device may include a welding driving component, which drives the welding assembly 102 to move along the welding track to weld the object to be welded.

[0101] It is understandable that after the clamping component 101 clamps the object to be welded, the welding assembly 102 moves to a position close to the object to be welded to weld the object to be welded. After welding is completed, the welding assembly 102 moves away from the position close to the object to be welded so as to take out the welded object from the clamping component 101, and put the next object to be welded in the clamping component 101 so that the clamping component 101 clamps the next object to be welded. After that, the welding assembly 102 approaches the object to be welded again and welds the object to be welded according to the welding track. The above steps are repeated to realize that the welding assembly 102 welds a batch of objects to be welded.

[0102] In some embodiments, the welding drive component can not only drive the welding assembly 102 to move along the welding trajectory, but also drive the welding assembly 102 to move away from a position close to the object to be welded after welding the current object to be welded is completed, and after the next object to be welded is clamped by the clamping component 101, drive the welding assembly 102 to move in a direction close to the object to be welded so as to weld the object to be welded.

[0103] It is understandable that when the dust removal component 103 is removing dust from the clamping component 101, the clamping component 101 is not clamping the object to be welded, and the welding assembly 102 is located away from the clamping component 101, so that the dust removal component 103 can clean the clamping component 101 in all directions.

[0104] In some embodiments, the welding drive component can be controlled to control the welding assembly 102 to move away from a position close to the object to be welded after the welding of the previous object to be welded is completed. That is, the welding assembly 102 is placed at a position away from the clamping component 101, so that the welding assembly 102 will not affect the dust removal of the clamping component 101 by the dust removal component 103, thereby eliminating the need to shut down the welding device for dust removal.

[0105] When the dust removal component 103 completes dust removal on the clamping component 101 and moves away from the clamping component 101, the welding driving component can immediately drive the welding assembly 102 to descend so that the welding assembly 102 continues to weld the object to be welded. In other words, through the welding driving component and the driving component 104, the welding process of the welding assembly 102 and the dust removal process of the dust removal component 103 can be prevented from interfering with each other, so that the welding device does not need to be stopped for dust removal.

[0106] The dust removal component 103 moves to the clamping component 101 when the welding assembly 102 is not welding: the gap between the welding assembly 102 dusting the previous object to be welded and the next object to be welded.

[0107] That is to say, in the interval between two welding processes of the welding assembly 102, the dust removal component 103 can be arranged to move to the clamping component 101 to remove dust from the clamping component 101, so that the welding device can remove dust from the clamping component 101 without stopping.

[0108] The dust removal component 103 moves to the clamping component 101 by: moving to a position directly facing the surface of the clamping component 101 close to the welding assembly 102. In some embodiments, the dust removal component 103 can directly face the surface of the clamping component 101 without contacting it. In other embodiments, the dust removal component 103 can also contact the surface of the clamping component 101.

[0109] The dust removal component 103 may be moved away from the clamping component 101 to a position that is not directly opposite to the surface of the clamping component 101 close to the welding assembly 102. For example, the dust removal component 103 may be moved to one side of the clamping component 101.

[0110] In some embodiments, the driving component 104 can drive the dust removal component 103 to move to the clamping component 101, and control the dust removal component 103 to move along a preset dust removal path during the dust removal process of the dust removal component 103. The driving component 104 can also drive the dust removal component 103 to move away from the clamping component 101 after the dust removal process of the dust removal component 103 is completed.

[0111] In the above technical solution, the dust removal component 103 will not affect the welding of the object to be welded by the welding assembly 102, and can realize automatic dust removal of the clamping component 101. While solving the problem of the quality of the object to be welded being affected by excessive welding ash accumulated on the clamping component 101, it reduces the influence of the dust removal step of the dust removal component 103 on the production capacity of the object to be welded.

[0112] Continue to refer Figures 3 to 5 According to some embodiments of the present application, the clamping component 101 is used to define a clamping position 1011 for accommodating an object to be welded, and the welding assembly 102 is configured to be located above the clamping position 1011 to weld the object to be welded.

[0113] The clamping member 101 clamps the object to be welded in the clamping position 1011. Specifically, when the object to be welded is in the clamping position 1011, the clamping member 101 clamps the outer peripheral surface of the object to be welded. The welding assembly 102 is located above the clamping position 1011, that is, the welding assembly 102 is located above the object to be welded, so as to weld the object to be welded.

[0114] The upward direction may be a direction opposite to the direction indicated by the gravity of the clamping member 101 .

[0115] In some embodiments, the clamping member 101 may enclose a receiving cavity as a clamping position 1011. The object to be welded is located in the clamping position 1011, and the outer peripheral surface of the object to be welded is clamped by the clamping member 101. The number of the clamping positions 1011 may be one or more, such as two, three or more.

[0116] In some embodiments, the clamping member 101 may include two first clamping structures 101a disposed opposite to each other along a first direction and two second clamping structures 101b disposed opposite to each other along a second direction. The two first clamping structures 101a and the two second clamping structures 101b are combined to form a clamping position 1011. When the object to be welded is located in the clamping position 1011, the inner walls of the first clamping structure 101a and the second clamping structure 101b facing the clamping position 1011 both contact the object to be welded to clamp the object to be welded.

[0117] The clamping method of the clamping component 101 is described below by taking the battery shell as an example of the object to be welded.

[0118] The shell has an opening, and when the shell is located in the clamping position 1011, the opening is arranged upward, and the first clamping structure 101a and the second clamping structure 101b contact the outer peripheral surface of the shell arranged along the circumference of the opening. The opening shape of the clamping position 1011 can match the opening shape of the shell, so that the opening of the shell and the opening of the clamping position 1011 overlap.

[0119] The end cover is covered on the opening, and the welding assembly 102 welds the covered end cover and the shell.

[0120] It is understandable that, since the welding assembly 102 is located above the clamping position 1011 , the welding ash generated during welding of the welding assembly 102 inevitably falls onto the surface of the clamping part 101 near the clamping position 1011 under the action of gravity.

[0121] When the welding assembly 102 is not welding, the welding assembly 102 can move in a direction away from the clamping position 1011 and still be located above the clamping position 1011, so as to reduce the moving stroke while not hindering the dust removal of the dust removal component 103.

[0122] When dusting the clamping part 101, the dust removal part 103 moves to the side of the welding assembly 102 close to the clamping position 1011 and is located above the clamping part 101, so as to clean the welding ash on the surface of the clamping part 101 close to the welding assembly 102. After the dust removal is completed, it is moved away from the clamping part 101.

[0123] In the above technical solution, since the dust removal component 103 is moved to the clamping component 101 only when the welding assembly 102 is not welding, it will not affect the welding process of the welding assembly 102 located above the clamping position 1011 on the object to be welded, thereby reducing the impact of the dust removal step of the dust removal component 103 on the production capacity of the object to be welded.

[0124] According to some embodiments of the present application, the dust removal component 103 is configured to be able to move to a surface of the clamping component 101 close to the welding assembly 102 to remove dust from the clamping component 101 .

[0125] That is, during the dust removal process, the dust removal components 103 are in contact with the surface of the clamping component 101 close to the welding assembly 102 .

[0126] In this way, the welding ash on the surface of the clamping component 101 can be removed more efficiently. Most of the welding ash generated by the welding component 102 is attached to the surface of the clamping component 101 close to the welding component 102. Therefore, the dust removal component 103 is arranged to contact the surface of the clamping component 101 close to the welding component 102, so that the clamping component 101 can be cleaned in a targeted manner to improve the dust removal efficiency.

[0127] According to some embodiments of the present application, the dust removal component 103 is configured to move along the welding track to remove dust from the clamping component 101 .

[0128] During the welding process, the welding assembly 102 moves along the welding track to weld the object to be welded. Therefore, the welding ash generated by the welding assembly 102 also falls along the welding track, so that the welding ash is distributed along the welding track.

[0129] The dust removing component 103 removes dust from the clamping component 101 while moving along the welding track.

[0130] In the above technical solution, the dust removal component 103 moves along the welding track to remove dust from the clamping component 101, so that more welding ash on the welding track can be removed in a targeted manner.

[0131] According to some embodiments of the present application, when the clamping component 101 is used to define the clamping position 1011 , the orthographic projection of the welding trajectory on the clamping position 1011 coincides with the periphery of the clamping position 1011 .

[0132] That is to say, during the welding process, the welding assembly 102 moves along the periphery of the clamping position 1011 to weld the object to be welded at the periphery of the clamping position 1011 .

[0133] For example, when the battery shell is located in the clamping position 1011, the opening of the shell coincides with the opening of the clamping position 1011, that is, the periphery of the opening of the shell coincides with the periphery of the clamping position 1011, and the clamping component 101 clamps the outer peripheral surface arranged along the periphery of the opening of the shell, and the welding trajectory is the periphery of the opening of the shell.

[0134] In other words, the welding trajectory is the boundary line where the clamping member 101 contacts the object to be welded.

[0135] In this way, welding ash generated by the welding assembly 102 during the welding process will fall on the periphery of the clamping position 1011, so that the welding ash on the surface of the clamping component 101 at the periphery of the clamping position 1011 is distributed along the welding track.

[0136] In the above technical solution, the dust removal component 103 removes dust from the clamping component 101 along the welding track, which can remove as much welding ash distributed on the surface of the clamping component 101 as possible, thereby improving the dust removal efficiency of the clamping component 101.

[0137] Continue to refer Figures 3 to 5 According to some embodiments of the present application, the driving component 104 includes: a first sub-driving component 104a, which is configured to drive the dust removal component 103 to move along the welding trajectory; a second sub-driving component 104b, which is configured to drive the dust removal component 103 to move to the clamping component 101, and after the dust removal is completed, drive the dust removal component 103 to move away from the clamping component 101.

[0138] In some embodiments, when the dust removal component 103 contacts the surface of the clamping component 101 during dust removal, the second sub-driving component 104b can drive the dust removal component 103 to move above the clamping component 101, and the first sub-driving component 104a can also drive the dust removal component 103 located above the clamping component 101 to move toward the clamping component 101, so that the dust removal component 103 contacts the surface of the clamping component 101. Then, the first sub-driving component 104a drives the dust removal component 103 in contact with the surface of the clamping component 101 to move along the welding track.

[0139] In other embodiments, the dust removal component 103 does not contact the surface of the clamping component 101 during dust removal, but is only located above the clamping component 101. The second sub-driving component 104b drives the dust removal component 103 to move above the clamping component 101, and then the first clamping component 101 drives the dust removal component 103 located above the clamping component 101 to move along the welding track.

[0140] The first sub-driving component 104a is used to drive the movement of the dust removal component 103 during the dust removal process, and the second sub-driving component 104b is used to drive the movement of the dust removal component 103 before and after dust removal, so as to accurately control the stroke of the dust removal component 103 and enable the dust removal component 103 to automatically remove dust from the clamping component 101 without affecting the welding of the welding assembly 102 on the object to be welded.

[0141] According to some embodiments of the present application, the first sub-driving component 104a is further configured to: drive the welding assembly 102 to move along a welding track.

[0142] That is, the welding assembly 102 and the dust removal component 103 share the first sub-driving component 104 a .

[0143] In some embodiments, when the second sub-driving component 104b drives the dust removal component 103 to move above the clamping component 101, the welding assembly 102 is located above the dust removal component 103. In this way, the welding track driven by the first sub-driving component 104a to drive the dust removal component 103 to move is highly consistent with the welding track driven by the welding assembly 102 to move.

[0144] When the dust removing component 103 needs to contact the surface of the clamping component 101, after the dust removing component 103 moves above the clamping component 101, the first sub-driving component 104a drives the dust removing component 103 and the welding assembly 102 located above the dust removing component 103 to descend together until the dust removing component 103 contacts the surface of the clamping component 101, and then the first sub-driving component 104a drives the dust removing component 103 and the welding assembly 102 to move along the welding trajectory.

[0145] When the dust removing component 103 does not need to contact the surface of the clamping component 101, after the dust removing component 103 moves above the clamping component 101, the first sub-driving component 104a directly drives the dust removing component 103 and the welding assembly 102 located above the dust removing component 103 to move along the welding track.

[0146] It can be understood that in the process of the first sub-driving component 104a driving the welding assembly 102 and the dust removal component 103 to move together, the welding assembly 102 is located above the dust removal component 103, the welding assembly 102 does not perform welding, and does not hinder the dust removal component 103 from dusting the clamping component 101. Only the position of the welding assembly 102 changes.

[0147] It is worth noting that the first sub-driving component 104a and the welding driving component can be the same mechanism.

[0148] The first sub-driving component 104a may include a first driving unit and a second driving unit. The first driving unit is used to drive the dust removal component 103 and the welding assembly 102 to move up and down. The direction of the up and down movement is: the same direction as the gravity direction of the dust removal component 103 / welding assembly 102 and the opposite direction. The first driving unit may be a Z-axis servo motor.

[0149] The second driving unit is used to drive the dust removal component 103 and the welding assembly 102 to move along the welding track. The second driving unit may include an X-axis servo motor and a Y-axis servo motor.

[0150] It is understandable that the first sub-driving component 104a and the second sub-driving component 104b have already set the travel in advance, including the moving track of the welding component 102 during the welding process of the welding component 102, and the moving track of the dust removal component 103 when the dust removal component 103 is removing dust. For example, after the first sub-driving component 104a drives the welding component 102 to move to complete the welding of a preset number of objects to be welded, the second sub-driving component 104b moves the dust removal component 103 to the clamping component 101, and then the first sub-driving component 104a drives the dust removal component 103 to move, and at the same time drives the welding component 102 located above the dust removal component 103 to move together, so that the dust removal component 103 removes dust from the clamping component 101.

[0151] In the above technical solution, the welding component 102 and the dust removal component 103 share the first sub-driving component 104a. On the one hand, there is no need to additionally set up a driving component 104 for driving the dust removal component 103 to move along the welding trajectory, thereby saving costs. On the other hand, the moving trajectory of the dust removal component 103 is highly overlapped with the moving trajectory of the welding component 102, thereby improving the reliability of the dust removal component 103 moving along the welding trajectory, so that the dust removal component 103 can efficiently remove the welding ash dropped on the clamping component 101 during the welding process of the welding component 102.

[0152] Continue to refer Figures 3 to 5 According to some embodiments of the present application, the welding assembly 102 includes: a first mounting seat 1021; a welding head 102a disposed on the first mounting seat 1021, the welding head 102a is used to weld the object to be welded, wherein the dust removal component 103 is disposed on the first mounting seat 1021.

[0153] In some embodiments, the welding head 102a may include but is not limited to ultrasonic welding of the object to be welded.

[0154] In some embodiments, the welding head 102a is used to perform ultrasonic welding on the object to be welded, and the welding assembly 102 may also include: a transducer, a horn and a cylinder. The horn is connected to the end of the welding head 102a, the cylinder is connected to the end of the horn away from the welding head 102a, and the transducer is connected to the horn.

[0155] The first mounting seat 1021 can be slidably connected to the first sub-driving component 104a, so that the first sub-driving component 104a can drive the first mounting seat 1021 to move, thereby driving the welding head 102a and the dust removal component 103 connected to the first mounting seat 1021 to move. The first mounting seat 1021 and the first sub-driving component 104a can be connected in a manner well known to those skilled in the art, and it is only necessary to realize that the first sub-driving component 104a can control the first mounting seat 1021 to move in the above manner.

[0156] In the above technical solution, the dust removal component 103 and the welding head 102a are arranged on the same first mounting seat 1021, so that the first sub-driving component 104a can drive both the dust removal component 103 and the welding head 102a to move, and the moving trajectories of the dust removal component 103 and the welding head 102a are highly overlapped.

[0157] refer to Figures 3 to 11 ,in, Figure 6 A schematic diagram of a three-dimensional structure in which a dust removal component of some embodiments of the present application is installed on a first installation structure; Figure 7 This is a schematic diagram of a front view structure in which a dust removal component of some embodiments of the present application is installed on a first installation structure; Figure 8A schematic diagram of a side view of a dust removal component installed on a first installation structure in some embodiments of the present application;

[0159] According to some embodiments of the present application, the welding device also includes: a first mounting structure 1022 arranged on a first mounting seat 1021, the dust removal component 103 is rotatably mounted on the first mounting structure 1022 through a rotating axis, and the second sub-driving component 104b is configured to: drive the dust removal component 103 to rotate around the rotating axis to the clamping component 101, and after the dust removal is completed, drive the dust removal component 103 to move away from the clamping component 101.

[0160] In some embodiments, the second sub-driving component 104b may include but is not limited to a component such as a rotary cylinder that can drive the dust removal component 103 to rotate.

[0161] In some embodiments, the rotating shaft may be a rotating flange in a rotating cylinder, and the rotating motor in the rotating cylinder may drive the rotating flange to rotate, and the dust removal component 103 may be connected to the rotating flange through a guide post mounting plate 105. One end of the guide post mounting plate 105 is connected to the dust removal component 103, and the other end of the guide post mounting plate 105 may include a plurality of circumferentially arranged first mounting holes 51, and each first mounting hole 51 is connected to the rotating flange by a bolt, so that the guide post mounting plate 105 is connected to the rotating flange.

[0162] refer to Figures 12 to 17 , Fig.12 This is a schematic diagram of the three-dimensional structure of the guide post mounting plate of some embodiments of the present application; Fig.13 This is a schematic diagram of the front structural view of the guide post mounting plate of some embodiments of the present application; Fig.14 This is a schematic diagram of the rear view structure of the guide post mounting plate of some embodiments of the present application; Fig.15 for Fig.14 The cross-sectional view in the AA direction; Fig.16 It is a side view structural schematic diagram of the guide post mounting plate of some embodiments of the present application; Fig.17 This is a schematic diagram of the top view of the guide column mounting plate of some embodiments of the present application.

[0163] In some embodiments, the guide post mounting plate 105 may include a guide post mounting seat 1051 and a mounting plate portion 1052 fixed to the guide post mounting seat 1051. The dust removal component 103 is connected to the guide post mounting seat 1051, and the first mounting hole 51 is located at the end of the mounting plate portion 1052 away from the guide post mounting seat 1051.

[0164] refer to Figure 7 as well as Fig.11 In some embodiments, the second sub-driving component 104b can drive the rotating flange to rotate in a clockwise direction until the dust removal component 103 rotates to the first position (refer to Figure 7 ), and rotate counterclockwise until the dust removal component 103 rotates to the second position (reference Fig.11 ), the angle between the first position and the second position may be 180°. That is, the second sub-driving component 104b can drive the dust removal component 103 to move back and forth between the first position and the second position. The first position may be a position above the clamping component 101, for example, a position directly opposite to the welding head 102a, and the second position may be a position where the dust removal component 103 is located after being removed from the clamping component 101.

[0165] refer to Figures 6 to 10 In some embodiments, the first mounting structure 1022 may include a supporting rib 1022a, a first mounting plate 1022b, and a second mounting plate 1022c. The first mounting plate 1022b and the second mounting plate 1022c are respectively connected to opposite sides of the supporting rib 1022a. The first mounting plate 1022b may be connected to the guide column mounting plate 105, and the second mounting plate 1022c may be connected to the first mounting seat 1021. The second mounting plate 1022c may also be slidably connected to the first sub-driving component 104a. For example, the second mounting plate 1022c may be slidably connected to the slide rail on the first sub-driving component 104a, so that the first sub-driving component 104a can drive the first mounting structure 1022 to move.

[0166] In the above technical solution, through the second sub-driving component 104b, the dust removal component 103 is rotated to the clamping component 101 only when dust removal is needed, and the dust removal component 103 and the welding assembly 102 can share the first sub-driving component 104a, so that the first sub-driving component 104a can drive the dust removal component 103 to move according to the welding trajectory.

[0167] refer to Figures 3 to 10 According to some embodiments of the present application, the second sub-driving component 104b is installed on the first mounting seat 1021.

[0168] In some embodiments, the second sub-driving component 104 b can be mounted on the first mounting seat 1021 by being fixed to the first mounting structure 1022 .

[0169] Specifically, in some embodiments, the guide column mounting plate 105 is connected to the first mounting plate 1022 b, thereby connecting the dust removal component 103 and the first mounting structure 1022 .

[0170] The second sub-driving component 104b can be installed on a side of the first mounting plate 1022b away from the guide post mounting plate 105, and then fixed to the first mounting structure 1022. In other words, the guide post mounting plate 105 and the second sub-driving component 104b are integrated on the first mounting plate 1022b.

[0171] Specifically, the second sub-driving component 104b can be a rotating cylinder, and the first mounting plate 1022b has multiple second mounting holes matching the multiple first mounting holes 51. The bolts pass through the first mounting holes 51 and the second mounting holes and are fixed to the rotating flange, thereby installing the second sub-driving component 104b on the first mounting plate 1022b.

[0172] In the above technical solution, the second sub-driving component 104b, the welding head 102a and the dust removal component 103 are all installed on the first mounting seat 1021, so that the first sub-driving component 104a drives the dust removal component 103 to move along the welding track while driving the second sub-driving component 104b to move along the welding track, thereby maintaining the relative position between the second sub-driving component 104b and the dust removal component 103 unchanged, thereby avoiding the problem of the dust removal component 103 moving away from the clamping component 101 during the dust removal process.

[0173] refer to Figures 3 to 10 According to some embodiments of the present application, the dust removal component 103 includes: a second mounting seat 40; a dust removal head 1031, mounted on the second mounting seat 40, the dust removal head 1031 is used to contact the surface of the clamping component 101, the dust removal head 1031 has a first hollow cavity 31, and the first hollow cavity 31 is used to define a first dust removal port 31a of the dust removal head 1031.

[0174] The first hollow cavity 31 allows dust removal airflow to pass through, and dust is removed from the clamping component 101 through the first dust removal port 31 a.

[0175] In some embodiments, negative pressure may be formed in the first hollow cavity 31 , thereby adsorbing welding ash on the surface of the clamping component 101 through the first dust removal port 31 a .

[0176] In some other embodiments, a positive pressure may also be formed in the first hollow cavity 31, so that the welding ash on the surface of the clamping component 101 can be blown away through the first dust removal port 31a.

[0177] In some embodiments, the first dust removal port 31 a is an end opening of the first hollow cavity 31 , and the first dust removal port 31 a is used to contact the surface of the clamping member 101 .

[0178] In the above technical solution, the dust removal airflow can be transported through the first hollow cavity 31, and the welding ash on the surface of the clamping component 101 can be efficiently removed at a close distance through the first dust removal port 31a.

[0179] refer to Figures 6 to 10 ,as well as Figures 18 to 20 ,in, Fig.18 A schematic diagram of the three-dimensional structure of a dust removal head according to some embodiments of the present application; Fig.19 This is a schematic diagram of the main structure of the dust removal head of some embodiments of the present application; Fig. 20 for Fig.19 Cross-sectional view along the BB direction.

[0180] According to some embodiments of the present application, the dust removal head 1031 includes: a first mounting portion 41, fixed to a second mounting seat 40; a cleaning portion 42 connected to the first mounting portion 41, the first hollow cavity 31 axially penetrates the first mounting portion 41 and the cleaning portion 42, the cleaning portion 42 is used to contact the surface of the clamping component 101, and the surface of the cleaning portion 42 used to contact the clamping component 101 is a flexible surface.

[0181] The flexible surface means that the surface of the cleaning portion 42 for contacting with the clamping member 101 has a soft property.

[0182] In some embodiments, the cleaning portion 42 may be made of a flexible material.

[0183] In some embodiments, the first mounting portion 41 may be made of a material having a greater hardness than the cleaning portion 42 , so that the first mounting portion 41 can be stably mounted on the second mounting seat 40 .

[0184] In some embodiments, the material of the first mounting portion 41 may include but is not limited to metal, ceramic, and other materials with relatively high rigidity.

[0185] In the above technical solution, the dust removal head 1031 may include a first mounting portion 41 and a cleaning portion 42 with different functions, so that the dust removal head 1031 can be stably connected to the second mounting seat 40 through the first mounting portion 41. The cleaning portion 42 is also in contact with the surface of the clamping component 101 during the movement, and the welding ash on the surface of the clamping component 101 is cleaned, which can strengthen the removal of welding ash attached to the surface of the clamping component 101. The cleaning portion 42 is in contact with the clamping component 101 through a flexible surface, which can reduce the damage caused by the cleaning portion 42 to the surface of the clamping component 101 during the movement.

[0186] According to some embodiments of the present application, the cleaning part 42 is a brush.

[0187] The brush has a certain electrostatic adsorption property, which can adsorb welding ash on the brush.

[0188] In other embodiments, the material of the cleaning portion 42 may also include other flexible materials besides the brush.

[0189] In the above technical solution, since the brush is relatively soft, it can reduce scratches and damages to the surface of the clamping component 101 during the dust removal process. In addition, when the brush contacts the surface of the clamping component 101, a certain friction is generated between the brush and the surface of the clamping component 101, so that the welding ash firmly attached to the surface of the clamping component 101 can be shoveled up, and then the shoveled welding ash is removed through the first dust removal port 31a, thereby achieving efficient dust removal on the surface of the clamping component 101.

[0190] refer to Figures 6 to 10 According to some embodiments of the present application, the dust removal component 103 also includes: a collector 1032, which is installed on the second mounting seat 40 and has a second hollow cavity 32, the dust removal head 1031 is installed in the second hollow cavity 32, and the second hollow cavity 32 is connected to the first hollow cavity 31, and the collector 1032 is constructed to form a negative pressure in the second hollow cavity 32 during dust removal by the dust removal component 103.

[0191] The collecting hood 1032 can concentrate more airflow, forming negative pressure in the second hollow cavity 32, thereby forming negative pressure in the first hollow cavity 31 connected to the second hollow cavity 32, so that the first dust removal port 31a can absorb the welding ash on the surface of the clamping component 101 into the first hollow cavity 31.

[0192] In some embodiments, the collecting cover 1032 may be connected to an exhaust device, so that the exhaust device can exhaust air from the second hollow cavity 32 , thereby forming a negative pressure in the second hollow cavity 32 .

[0193] In the above technical solution, the collecting cover 1032 has the function of concentrating the airflow, so that the second hollow cavity 32 forms a larger negative pressure space, thereby enhancing the ability of the first hollow cavity 31 to adsorb welding ash on the surface of the clamping component 101 through negative pressure.

[0194] Continue to refer Figures 6 to 10According to some embodiments of the present application, the collecting cover 1032 includes: a first part 1032a, a second mounting part 1032b and a second part 1032c connected in sequence, the second hollow cavity 32 axially penetrates the first part 1032a, the second mounting part 1032b and the second part 1032c, the dust removal head 1031 is axially installed on the inner wall of the second mounting part 1032b, and the second hollow cavity 32 in the second part 1032c also surrounds part of the outer circumference of the dust removal head 1031.

[0195] During the period when the dust removal component 103 removes dust from the clamping component 101, the second portion 1032c is disposed closer to the clamping component 101 than the first portion 1032a. The dust removal head 1031 may be located only in the second mounting portion 1032b and the second hollow cavity 32 of the second portion 1032c.

[0196] In some embodiments, the inner diameter of the second hollow cavity 32 in the second mounting portion 1032b can be smaller than the inner diameter of the second hollow cavity 32 in the first portion 1032a and the second portion 1032c. When the dust removal head 1031 is fixed in the second mounting portion 1032b, the dust removal head 1031 contacts the inner wall of the second mounting portion 1032b to improve the stability of the installation of the dust removal head 1031.

[0197] refer to Figures 8 to 9 In some embodiments, the first mounting portion 41 of the dust removal head 1031 is mounted on the inner wall of the second mounting portion 1032b. Figures 18 to 20 The outer periphery of the first mounting portion 41 may have two mounting grooves 41a disposed opposite to each other. Figure 23 to Figure 24 The second mounting portion 1032b has a third mounting hole 52, and the third mounting hole 52 has a locking member adapted to the mounting groove 41a. The locking member is embedded in the mounting groove 41a to limit the first mounting portion 41.

[0198] Continue to refer Figures 6 to 10 The second portion 1032c is disposed around at least a portion of the outer circumference of the cleaning portion 42, and an annular cavity is defined between the second portion 1032c and the outer circumference of the cleaning portion 42. In this way, when the dust removal head 1031 absorbs the welding ash on the surface of the clamping component 101 by negative pressure, the welding ash can also be sucked into the annular cavity, thereby increasing the dust removal area of ​​the dust removal component 103 on the surface of the clamping component 101, thereby enhancing the dust removal effect.

[0199] In some embodiments, the inner diameter of the second hollow cavity 32 in the first part 1032a is larger than the inner diameter of the second hollow cavity 32 in the second part 1032c, so that the first part 1032a can concentrate more airflow to form a larger negative pressure space, thereby enhancing the adsorption effect of the first dust removal port 31a of the first hollow cavity 31 on the welding ash on the surface of the clamping part 101.

[0200] In the above technical solution, by providing the first portion 1032a, it is possible to concentrate the airflow to form a negative pressure. By providing the second mounting portion 1032b, the dust removal head 1031 can be fixed. By providing the second portion 1032c surrounding a portion of the outer circumference of the dust removal head 1031, the welding ash is sucked away through the annular cavity formed between the second hollow cavity 32 and the dust removal head 1031, thereby further enhancing the dust removal efficiency of the dust removal component 103 on the clamping component 101.

[0201] According to some embodiments of the present application, in a direction from the second portion 1032c to the first portion 1032a, the inner diameter of the first portion 1032a gradually increases.

[0202] That is, the first portion 1032a is in a funnel shape.

[0203] In some embodiments, the opening shape of the first portion 1032a away from the second portion 1032c may be rectangular, and the opening shape of the first portion 1032a close to the second portion 1032c may be circular. In this way, the cross-sectional shape of the second mounting portion 1032b and the second portion 1032c may continue the circular opening shape to form a columnar shape, thereby simplifying the manufacturing process.

[0204] In the above technical solution, by setting the first portion 1032a to be in a funnel shape, the airflow can be concentrated into the first hollow cavity 31, thereby enhancing the cleaning power of the dust removal head 1031 on the surface of the clamping component 101.

[0205] refer to Figure 21 to Figure 25 , Fig.21 A schematic diagram of the three-dimensional structure of a dust removal component in some embodiments of the present application; Fig. 22 A schematic diagram of the top view of the dust removal component of some embodiments of the present application; Fig.23 A schematic diagram of the structure of the dust removal component in some embodiments of the present application from a bottom view; Fig.24 for Fig.23 Cross-sectional view in CC direction; Fig.25 for Fig.23 Schematic diagram of the side view structure in the D direction.

[0206] According to some embodiments of the present application, the second mounting portion 1032b also includes: a plurality of third hollow cavities 33 arranged at intervals along the outer periphery of the dust removal head 1031, the third hollow cavity 33 penetrates the second mounting portion 1032b along the axial direction of the second hollow cavity 32, and is connected to the second hollow cavities 32 of the first portion 1032a and the second portion 1032c.

[0207] The third hollow cavity 33 is located at the periphery of the dust removal head 1031 , and the first hollow cavity 31 is located inside the dust removal head 1031 , and both are connected to the second hollow cavity 32 , and both can form negative pressure to remove dust from the clamping component 101 .

[0208] In some embodiments, an annular cavity is defined between the second portion 1032c and the outer circumferential surface of the cleaning portion 42, and one end of the third hollow cavity 33 in the axial direction is connected to the second hollow cavity 32 of the first portion 1032a, and the other end is connected to the annular cavity. Weld ash is sucked from the annular cavity and adsorbed into the second hollow cavity 32 of the first portion 1032a through the third hollow cavity 33.

[0209] When the cleaning part 42 is a brush, during the dust removal process, the first hollow cavity 31 in the brush, the outer peripheral surface of the brush, and the gap in the brush will absorb welding ash. Since the third hollow cavity 33 is provided, the welding ash absorbed in the annular cavity can be sucked away, and the annular cavity surrounds the brush, so that the welding ash on the outer peripheral surface of the brush can also be absorbed away, which can enhance the cleaning power of the brush on the clamping component 101.

[0210] In some embodiments, the third hollow cavity 33 also exposes the outer circumference of the first mounting portion 41 .

[0211] In some embodiments, a plurality of third hollow cavities 33 may be arranged at equal intervals around the outer circumference of the dust removal head 1031, so as to evenly absorb the welding ash in the annular cavity along the circumference of the annular cavity. The number of third hollow cavities 33 may include but is not limited to 2, 3, 4 or more.

[0212] In some embodiments, the locking member in the second mounting portion 1032 b may be disposed between two adjacent third hollow cavities 33 .

[0213] In the above technical solution, the first hollow cavity 31 forms a dust removal channel located inside the dust removal head 1031, and the third hollow cavity 33 forms a dust removal channel located outside the dust removal head 1031. Through multiple dust removal channels, the welding ash of the clamping component 101 is adsorbed, further enhancing the dust removal efficiency of the dust removal component 103 on the clamping component 101.

[0214] refer to Figures 3 to 9 According to some embodiments of the present application, the bottom of the dust removal head 1031 protrudes from the bottom of the second hollow cavity 32 , and the bottom of the dust removal head 1031 is used to contact the surface of the clamping component 101 .

[0215] The bottom of the second hollow cavity 32 is the bottom of the current collecting cover 1032, and the bottom of the dust removal head 1031 protrudes from the bottom of the second hollow cavity 32, that is, the bottom of the dust removal head 1031 is closer to the surface of the clamping component 101 close to the welding assembly 102 than the bottom of the current collecting cover 1032. In this way, when the bottom of the dust removal head 1031 contacts the surface of the clamping component 101, the bottom of the current collecting cover 1032 will not touch the surface of the clamping component 101.

[0216] In the above technical solution, only the bottom of the dust removal head 1031 contacts the surface of the clamping component 101, reducing the probability of the bottom of the collecting cover 1032 touching the surface of the clamping component 101, thereby reducing the scratches or damages to the surface of the clamping component 101 caused by the dust removal component 103.

[0217] According to some embodiments of the present application, the bottom of the dust removal head 1031 protrudes from the bottom of the second hollow cavity 32 by 2 mm to 7 mm.

[0218] Optionally, the bottom of the dust removal head 1031 may protrude from the bottom of the second hollow cavity 32 by a dimension of 2 mm, 5 mm, etc.

[0219] Within the above range, the size of the bottom of the dust removal head 1031 protruding from the second hollow cavity 32 is not too small, which can greatly reduce the probability of the bottom of the collector 1032 touching the surface of the clamping component 101. On the other hand, within the above range, the distance between the bottom of the collector 1032 and the surface of the clamping component 101 is not too large, so that the second part 1032c arranged around the dust removal head 1031 can also have a good negative pressure dust removal effect on the clamping component 101.

[0220] refer to Figures 3 to 10 According to some embodiments of the present application, the dust removal component 103 further includes: a vibration component 1033 mounted on the second mounting seat 40, and the vibration component 1033 is configured to control the vibration of the dust removal head 1031 during dust removal by the dust removal component 103.

[0221] The vibration component 1033 itself can generate mechanical vibration. The vibration component 1033 and the dust removal head 1031 are both installed on the second mounting seat 40. In this way, the vibration component 1033 can transmit the vibration to the dust removal head 1031 through the second mounting seat 40, thereby controlling the vibration of the dust removal head 1031.

[0222] In some embodiments, the vibration component 1033 may be an ultrasonic transducer, which is an energy conversion device that can convert electrical energy into mechanical vibration.

[0223] In other embodiments, the vibration component 1033 may also include any other mechanism capable of generating mechanical vibration, such as but not limited to an electromechanical converter, an electromagnetic vibrator, a pneumatic actuator, a hydraulic motor, etc.

[0224] In the above technical solution, the vibration component 1033 can vibrate the welding ash attached to the surface of the clamping component 101, thereby improving the adsorption efficiency of the dust removal head 1031 on the welding ash, and further improving the dust removal efficiency of the dust removal component 103 on the clamping component 101.

[0225] refer to Figures 6 to 10 ,as well as Figure 21 to Figure 25 According to some embodiments of the present application, when the dust removal component 103 includes a current collecting cover 1032, the second mounting seat 40 includes a mounting cavity 40a, the mounting cavity 40a includes a first side wall 401 and a second side wall 402 relative to each other, the vibration component 1033 is located in the mounting cavity 40a and fixed to the first side wall 401, and the current collecting cover 1032 is located outside the mounting cavity 40a and fixed to the second side wall 402.

[0226] That is, the vibration component 1033 is installed on the inner wall of the installation cavity 40a, and the current collecting cover 1032 is installed on the outer wall of the installation cavity 40a. The vibration generated by the vibration component 1033 is transmitted to the current collecting cover 1032, and the vibration in the current collecting cover 1032 is then transmitted to the dust removal head 1031 installed in the current collecting cover 1032. The vibration component 1033 and the current collecting cover 1032 are respectively installed on different side walls of the installation cavity 40a, so that the path for the vibration generated by the vibration component 1033 to be transmitted to the current collecting cover 1032 is relatively long, and the vibration generated by the current collecting cover 1032 can be controlled not to be too strong.

[0227] There may be a gap between the vibration component 1033 and the second side wall 402 , that is, the vibration component 1033 and the second side wall 402 are not in contact with each other.

[0228] In some embodiments, the vibration component 1033 may be mounted on the first side wall 401 by bolt connection or the like. The first side wall 401 may have a fourth mounting hole 53 , and the bolt may be connected to the vibration component 1033 through the fourth mounting hole 53 .

[0229] In some embodiments, the current collecting cover 1032 may be mounted to the second side wall 402 by bolt connection or the like, so as to facilitate installation and removal of the current collecting cover 1032 .

[0230] In other embodiments, the side of the second side wall 402 away from the center of the installation cavity 40a can also be an annular groove with a notch adapted to the outer peripheral shape of the second installation portion 1032b. The second installation portion 1032b enters the annular groove from the notch and is installed on the outer wall of the installation cavity 40a by snap-fitting.

[0231] In the above technical solution, the vibration component 1033 and the current collecting cover 1032 are respectively installed on different side walls of the installation cavity 40a, so that the vibration amplitude transmitted from the vibration component 1033 to the current collecting cover 1032 is not too large, so that the current collecting cover 1032 is firmly connected to the outer wall of the installation cavity 40a.

[0232] refer to Figures 8 to 9 According to some embodiments of the present application, when the dust removal head 1031 includes a first mounting portion 41 , the dust removal head 1031 is fixed in the collector 1032 by a spring locking pin 43 .

[0233] The first mounting portion 41 can be connected to the second mounting portion 1032 b of the current collecting cover 1032 through a spring locking pin 43 . That is, the locking member is a spring locking pin 43 .

[0234] In some embodiments, the spring locking pin 43 can pass through the second mounting portion 1032b in an axial direction perpendicular to the second hollow cavity 32, that is, one end of the spring locking pin 43 is exposed from the outer wall of the second mounting portion 1032b, and the other end is exposed from the second hollow cavity 32 of the second mounting portion 1032b, and is embedded in the mounting groove on the outer periphery of the first mounting portion 41.

[0235] In some embodiments, the spring locking pin 43 may include: a plug 43a, a spring 43b, and a locking pin 43c connected in sequence. The end of the plug 43a away from the spring 43b is exposed to the outer wall of the second mounting portion 1032b. The locking pin 43c is exposed in the second mounting cavity 40a and embedded in the mounting groove of the first mounting portion 41 to lock the second mounting portion 1032b to the first mounting portion 41.

[0236] The plug 43a can play a role in blocking and shock absorption. The spring 43b has elastic deformation and can play a shock absorption effect. The locking pin 43c is used to fix, connect and prevent loosening. In this way, the spring locking pin 43 has a certain shock absorption effect, and the first mounting part 41 is fixed to the second mounting part 1032b, so that the dust removal head 1031 can be locked in the collector 1032 even under strong vibration, which is conducive to vibration conduction.

[0237] refer to Figures 6 to 10 According to some embodiments of the present application, when the welding assembly 102 includes a first mounting seat 1021 , the dust removal component 103 further includes: a buffer component 106 , and the mounting cavity 40a is mounted on the first mounting seat 1021 through the buffer component 106 .

[0238] In some embodiments, the dust removal component 103 can be mounted on the guide post mounting plate 105 through the buffer component 106, the guide post mounting plate 105 is mounted on the first mounting structure 1022, and the first mounting structure 1022 is connected to the first mounting seat 1021, and the buffer component 106 is located on the side of the mounting cavity 40a away from the collector 1032. In this way, the vibration generated by the vibration component 1033 in the mounting cavity 40a can be reduced by the buffer component 106. The vibration transmitted to the first mounting structure 1022 can further reduce the vibration transmitted to the first mounting seat 1021.

[0239] In some embodiments, a guide post 105a is installed on the guide post mounting plate 105. The guide post 105a is located at one end of the guide post 105a mounting plate 105 away from the first mounting structure 1022. The guide post 105a is used to connect the mounting cavity 40a. The guide post 105a can be installed on the guide post 105a mounting plate 105 by bolt connection. In some embodiments, the number of guide posts 105a can be two, and the two guide posts 105a are arranged opposite to each other.

[0240] The outer wall of the installation cavity 40a is provided with a connecting portion 40b adapted to the guide post 105a, and the connecting portion 40b has a guide post 105a installation hole, and the connecting portion 40b is sleeved on the guide post 105a through the guide post 105a installation hole. The buffer component 106 has a fifth installation hole so that the buffer component 106 can also be sleeved on the guide post 105a.

[0241] Specifically, the buffer component 106 may include a first sub-buffer component 106a and a second sub-buffer component 106b, wherein the first sub-buffer component 106a is located between the connecting portion 40b and the end of the guide column 105a mounting plate 105, and the second sub-buffer component 106b is located on the side of the connecting portion 40b away from the guide column 105a mounting plate 105. The guide column 105a mounting plate 105 and the mounting cavity 40a are not in direct contact, but are separated by the second sub-buffer component 106b. The first sub-buffer component 106a and the second sub-buffer component 106b are arranged along the axial direction of the guide column 105a, which can reduce the reciprocating vibration of the vibration component 1033 in the axial direction of the guide column 105a.

[0242] In some embodiments, the material of the buffer component 106 may include an elastic material, for example, including but not limited to rubber, polyurethane, etc.

[0243] In some embodiments, the diameter of the guide post 105a is smaller than the inner diameter of the fifth mounting hole, and a buffer retaining ring 60 may be sleeved on the guide post 105a to fill the gap between the buffer component 106 and the guide post 105a, specifically between the second sub-buffer component 106b and the guide post 105a.

[0244] In the above technical solution, the buffer component 106 can reduce the vibration of the vibration component 1033 in the installation cavity 40a from being transmitted to other structures of the first installation seat 1021 , thereby reducing the impact of the vibration on other structures on the first installation seat 1021 .

[0245] refer to Figures 3 to 5 According to some embodiments of the present application, when the welding assembly 102 includes a first mounting seat 1021, and the welding head 102a and the dust removal component 103 of the welding assembly 102 are both arranged on the first mounting seat 1021, the welding assembly 102 also includes a dust removal cover 102b arranged on the first mounting seat 1021, and the dust removal cover 102b has a second dust removal port, and the dust removal component 103 is constructed as follows: move to the first hollow cavity 31 of the dust removal head 1031 to face the second dust removal port, so that the dust removal cover 102b removes dust from the clamping component 101 via the second dust removal port and the first dust removal port 31a of the first hollow cavity 31.

[0246] During the movement of the dust removal component 103 along the welding track, the welding head 102a and the dust removal cover 102b will also be driven to move synchronously, so that the dust removal cover 102b can continuously remove dust from the clamping component 101 through the second dust removal port and the first dust removal port 31a during the dust removal process of the dust removal component 103.

[0247] In some embodiments, the welding assembly 102 and the dust removal component 103 share the first sub-driving component 104a, and the second sub-driving component 104b is used to drive the dust removal component 103 to move to a position where the first hollow cavity 31 of the dust removal head 1031 is opposite to the second dust removal port. The first sub-driving component 104a drives the first mounting seat 1021 to move along the welding track, so that when the dust removal head 1031 moves along the welding track, the second dust removal port of the dust cover 102b is always opposite to the first dust removal port 31a.

[0248] In some embodiments, during the dust removal of the dust removal component 103, negative pressure may be formed in the dust removal cover 102b, and the airflow in the first hollow cavity 31 may be sucked through the second dust removal port, thereby causing negative pressure to be formed in the first hollow cavity 31, so that the first dust removal port 31a absorbs welding ash on the surface of the clamping component 101. In other words, the dust removal cover 102b may serve as an exhaust device for the dust removal head 1031.

[0249] The dust cover 102b has an air suction port, which can be connected to an air suction device to form a negative pressure in the dust cover 102b.

[0250] In the above technical solution, the dust hood 102b can be a component in the welding assembly 102 for removing dust from the welding head 102a. During the welding process of the welding assembly 102, the dust hood 102b can be opened to allow the dust hood 102b to absorb the welding ash generated by the welding head 102a during the welding process in real time. Using the existing dust hood 102b in the welding assembly 102 as the exhaust device of the dust head 1031 can save costs and reduce the occupied space of the welding device.

[0251] According to some embodiments of the present application, the dust cover 102b is disposed on the outer peripheral surface of the welding head 102a.

[0252] During the welding process of the welding assembly 102, the dust cover 102b is covered on the outer peripheral surface of the welding head 102a, which can absorb the welding ash generated by the welding head 102a in real time and efficiently, reduce the amount of welding ash, and further reduce the welding ash falling on the surface of the clamping component 101.

[0253] When the welding assembly 102 is not welding, the first sub-driving component 104a drives the welding head 102a to rise in a direction away from the clamping position 1011. The second sub-driving component 104b drives the dust removal head 1031 to move to the welding head 102a directly below the clamping component 101, so that the dust cover 102b arranged around the periphery of the welding head 102a is also directly opposite to the first hollow cavity 31 of the dust removal head 1031. When the first sub-driving component 104a drives the dust removal head 1031 to move, the welding head 102a and the dust removal cover 102b also move together.

[0254] Since the dust removal hood 102b is covered on the outer peripheral surface of the welding head 102a, the dust removal head 1031 is directly opposite to the dust removal hood 102b and the welding head 102a, so that the moving trajectory of the dust removal head 1031 is highly overlapped with the moving trajectory of the welding head 102a and the dust removal hood 102b. In addition, during the movement of the dust removal head 1031, the dust removal hood 102b can accurately face the first hollow cavity 31 of the dust removal head 1031, thereby improving the reliability of the dust removal component 103 in removing dust from the clamping component 101.

[0255] According to some embodiments of the present application, when the dust removal component 103 includes the flow collecting cover 1032 , the dust removal component 103 is configured to move to the second hollow cavity 32 of the flow collecting cover 1032 to face the second dust removal port.

[0256] The dust removal hood can suck the airflow in the second hollow cavity 32 through the second dust removal port, thereby forming a negative pressure in the second hollow cavity 32 .

[0257] In the above technical solution, in order to better concentrate the dust removal airflow to the first hollow cavity 31, a collecting hood 1032 is provided. The collecting hood 1032 can collect the negative pressure airflow at the second dust removal port in a relatively concentrated manner and guide it to the first hollow cavity 31, so that a larger negative pressure is formed in the first hollow cavity 31, which is beneficial to enhance the dust removal force of the dust removal head 1031 on the clamping component 101.

[0258] According to some embodiments of the present application, when the collecting cover 1032 includes a first part 1032a, a second mounting part 1032b and a second part 1032c, the second dust removal port is directly opposite to the first part 1032a, and the orthographic projection of the second dust removal port on the surface of the first part 1032a coincides with the opening of the first part 1032a toward the second dust removal port.

[0259] That is, the shape of the second dust removal port is the same as the opening shape of the first portion 1032a toward the second dust removal port, and the size is the same.

[0260] The second dust removal opening and the first part 1032a may be directly opposite to each other: there is a gap between the first part 1032a and the second dust removal opening, or the first part 1032a and the second dust removal opening may be connected, that is, the opening edge of the first part 1032a facing the second dust removal opening is connected to the edge of the second dust removal opening.

[0261] In the above technical solution, the size and shape of the opening in the first part 1032a facing the second dust removal port are matched with the second dust removal port, which can further enhance the concentration effect of the collecting cover 1032 on the airflow transmitted from the second dust removal port, and guide more negative pressure airflow transmitted from the second dust removal port to the first dust removal port 31a, thereby further enhancing the dust removal effect of the dust removal head 1031 on the clamping component 101.

[0262] An embodiment of the present application provides a battery production device, which includes the welding device in the above embodiment, and the welding device is configured to weld the battery.

[0263] Battery production equipment is used to produce batteries.

[0264] The battery production equipment may have a conveying device for conveying the batteries. Figures 3 to 5 The conveying device can convey the batteries to be welded to the welding device one by one. After the clamping component 101 clamps the batteries to be welded, the welding assembly 102 moves toward the batteries to be welded and welds them.

[0265] After the welding of the battery to be welded currently in the clamping part 101 is completed, the welding assembly 102 moves away from the battery to be welded so as to take out the battery. At the same time, the conveying device conveys the next battery to be welded to the welding device. During the conveying, the welding assembly 102 does not perform welding.

[0266] Therefore, in some embodiments, the dust removal component 103 can be moved to the clamping component 101 during the transfer of the next battery to be welded, and the clamping component 101 is dusted. Before the next battery to be welded is transferred to the welding device, the dust removal component 103 completes the dust removal and moves away from the clamping component 101. In this way, the battery production equipment does not need to be shut down, and only a dust removal process is added between the two welding processes of the welding assembly 102, which will not affect the welding process of the welding assembly 102 on the batch of batteries.

[0267] Since the welding device can realize automatic dust removal of the clamping part 101 without affecting the welding process of the welding assembly 102, in the process of producing batteries using the battery production equipment, the welding ash on the clamping part 101 can be removed without stopping the machine, which can keep the welding ash on the clamping part 101 less, reduce the impact of the welding ash on the quality of the battery, and at the same time, maintain a high battery production capacity.

[0268] According to some embodiments of the present application, the welding device is configured to weld an end cover and a shell of a battery.

[0269] For the description of welding the end cover and the shell of the battery by the welding device, reference may be made to the relevant description in the above embodiment, which will not be repeated below.

[0270] It is understandable that in other embodiments, the welding device may not be limited to welding the end cover and the shell of the battery, but may also be used to weld other parts of the battery, such as welding the battery tabs and adapters.

[0271] In the above technical solution, the dust removal component in the welding device can remove the welding ash generated during the welding process of the end cover and the shell of the battery, thereby improving the problem of excessive welding ash on the clamping component affecting the subsequent welding process of the end cover and the shell of the battery, so that the produced batteries have higher quality.
