Description

Technical Field

[0001] This application belongs to the field of welding technology, specifically relating to a welding apparatus. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. The laser radiation heats the surface of the workpiece, and the surface heat diffuses into the interior through heat conduction. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool.

[0003] In related technologies, laser welding devices use clamping jaws and copper pillars to hold the workpieces to be welded. During the welding process, welding slag accumulates near the copper pillars. Currently, the treatment of welding slag mostly relies on manual cleaning of the clamping jaws and copper pillars periodically using brushes. Manual cleaning is time-consuming and labor-intensive, and the cleaning effect is greatly affected by human factors, making it difficult to guarantee the cleaning effect. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] The welding apparatus provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0036] like Figures 1 to 4 As shown, a welding apparatus according to some embodiments of this application is used for welding workpieces, including a welding station 10, a support member 20, and a welding mechanism (not shown in the figure). The welding station 10 has a first direction X and is provided with a first slag leakage hole 11 that extends through the first direction X. The support member 20 is disposed on the welding station 10 for fixing the workpiece to be welded. The support member 20 is provided with a second slag leakage hole 21 that extends through the first direction X. The second slag leakage hole 21 is adapted to face the workpiece and communicates with the first slag leakage hole 11. The welding mechanism is disposed on one side of the welding station 10 for welding workpieces.

[0037] In this embodiment, the welding station 10 of the welding device is provided with a first slag leakage hole 11 extending along the first direction X, and the support member 20 is provided with a second slag leakage hole 21 extending along the first direction X, and the second slag leakage hole 21 communicates with the first slag leakage hole 11, thereby forming a slag leakage channel extending along the first direction X. The workpiece is fixed on the support member 20 and located on the side of the second slag leakage hole 21 along the first direction X. When the welding mechanism welds the workpiece, the welding slag generated by the workpiece can enter the second slag leakage hole 21 and then leak out from the first slag leakage hole 11, thereby realizing automatic slag leakage. This process eliminates the need for manual cleaning of welding slag at the welding position, reducing manual labor and minimizing the impact of human factors on the cleaning effect.

[0038] Among them, such as Figure 1 As shown, the welding station 10 is a structural component for placing and installing the support 20 and other clamping or fixing components. For example, mounting holes can be provided on the welding station 10 to enable the installation of various components on it.

[0039] like Figure 2 As shown, the welding station 10 has a first direction X, which is perpendicular to the surface of the welding station 10. During welding, the first direction X is vertical. The welding station 10 is provided with a first slag leakage hole 11 that extends through the first direction X.

[0040] like Figure 2 As shown, the support member 20 is mounted on the welding station 10, for example, by bolts. The support member 20 is provided with a second slag leakage hole 21 that extends through the support member 20 along the first direction X. The second slag leakage hole 21 communicates with the first slag leakage hole 11, thereby forming a slag leakage channel.

[0041] The workpiece to be welded (e.g., a battery cell) is fixed on the support member 20, and the workpiece covers the second slag leakage hole 21. When the welding mechanism performs welding, the welding slag produced can fall into the second slag leakage hole 21, and then into the first slag leakage hole 11, and leak out from the first slag leakage hole 11, thus achieving slag removal. The workpiece to be welded can be fixed on the support member 20 by the clamping member 70, which can move closer to and further away from the support member 20 along the first direction X, thereby achieving clamping and loosening of the workpiece.

[0042] It should be noted that a container for collecting welding slag can be placed below the welding station 10. This container is opposite to the first slag leakage hole 11, so that the welding slag falling from the first slag leakage hole 11 can enter the container and achieve the collection of welding slag.

[0043] For example, the welding mechanism can be a laser welding mechanism, and correspondingly, the welding device is a laser welding device. Of course, the welding mechanism can also be other types of mechanisms, and can be flexibly set according to the actual situation. This application embodiment does not limit this.

[0044] Optionally, such as Figure 3 and Figure 4 As shown, the support member 20 includes a support block 22 and a support column 23. The support block 22 is disposed on and connected to the welding station 10. The support column 23 is detachably connected to the side of the support block 22 away from the welding station 10 along the first direction X. The second slag leakage hole 21 includes a first sub-hole 221 and a second sub-hole 231. The first sub-hole 221 penetrates the support block 22 along the first direction X, and the second sub-hole 231 penetrates the support column 23 along the first direction X. The first sub-hole 221 communicates with the first slag leakage hole 11, and the second sub-hole 231 communicates with the first sub-hole 221.

[0045] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, the support member 20 includes a detachable support block 22 and a support column 23, allowing the support column 23 to be detached from the support block 22. After repeated welding, the support member 20 may become damaged. By designing the support member 20 as two separate parts, only the damaged part needs to be replaced, eliminating the need to replace the entire support member 20 and reducing replacement costs.

[0046] Specifically, such as Figure 3 and Figure 4 As shown, the support component 20 includes a support block 22 and a support column 23. The support column 23 is detachably connected to the side of the support block 22 facing away from the welding station 10 along the first direction X. A first sub-hole 221 penetrates the support block 22 along the first direction X, and a second sub-hole 231 penetrates the support column 23 along the first direction X. The first sub-hole 221 communicates with the first slag leakage hole 11, and the second sub-hole 231 communicates with the first sub-hole 221, maintaining the continuity of the slag leakage channel. The support column 23 is the component that directly contacts the workpiece and needs to withstand the high temperature of welding. After multiple welding operations, the support column 23 may be damaged. The support column 23 can be removed from the support block 22 and replaced with a new one. This avoids replacing the entire support component 20, resulting in lower costs.

[0047] It should be noted that the support post 23 can be made of a material that does not easily adhere to the material of the part to be welded on the workpiece. For example, in the process of welding the tabs of a battery cell, the support post 23 can be made of brass. The support post 23 does not easily adhere to the tabs (copper foil or aluminum foil) of the battery cell, avoiding the need for subsequent separation if adhesion occurs, and improving the overall welding efficiency.

[0048] Optionally, such as Figure 4 As shown, the projected area of ​​the second sub-hole 231 on the plane perpendicular to the first direction X is smaller than the projected area of ​​the first sub-hole 221 on the plane perpendicular to the first direction X.

[0049] In this embodiment, the projected areas of the second sub-hole 231 and the first sub-hole 221 on a plane perpendicular to the first direction X are sequentially increased, so that welding slag can enter the first sub-hole 221 from the second sub-hole 231 along the ground.

[0050] Optionally, such as Figure 4 As shown, the projected area of ​​the first sub-hole 221 on the plane perpendicular to the first direction X is smaller than the projected area of ​​the first slag leakage hole 11 on the plane perpendicular to the first direction X.

[0051] In this embodiment, the projected areas of the first sub-hole 221 and the first slag leakage hole 11 on a plane perpendicular to the first direction X are sequentially increased, so that welding slag can enter the first slag leakage hole 11 from the first sub-hole 221 along the ground.

[0052] Therefore, the projected areas of the second sub-hole 231, the first sub-hole 221, and the first slag leakage hole 11 on the plane perpendicular to the first direction X increase sequentially. The welding slag enters the second sub-hole 231, the first sub-hole 221, and the first slag leakage hole 11 sequentially, thus reducing the probability of blockage when the welding slag moves within the entire slag leakage channel.

[0053] Specifically, such as Figure 4As shown, the support block 22 has a projection plane perpendicular to the first direction X, and the projection areas of the second sub-hole 231, the first sub-hole 221 and the first slag leakage hole 11 on the projection plane increase sequentially.

[0054] It should be noted that the "projected area of ​​the second sub-hole 231 on the plane perpendicular to the first direction X" should be understood as the area of ​​the shape enclosed by the projection of the edge of the second sub-hole 231 onto the plane perpendicular to the first direction X. Similarly, the first sub-hole 221 and the first slag leakage hole 11 should be understood in the same way.

[0055] Optionally, such as Figure 3 As shown, the support block 22 has multiple mounting slots 222 on the side away from the welding station 10, and at least one mounting slot 222 is detachably connected to the support column 23.

[0056] In this embodiment, the support block 22 has multiple mounting slots 222 on the side opposite to the welding station 10. The support column 23 can be selectively installed into one of the mounting slots 222, which is suitable for workpieces at different welding positions. Alternatively, there can be multiple support columns 23, which can be installed into multiple mounting slots 222 to support multiple positions of the workpiece, suitable for multi-point welding; or to support multiple workpieces simultaneously, suitable for multi-workpiece welding.

[0057] Specifically, such as Figure 3 As shown, the support block 22 is provided with multiple mounting slots 222, which extend along the first direction X and can penetrate the support block 22 from one side, facilitating the installation of the support column 23. After the support column 23 is installed into the mounting slot 222, it can be secured in the mounting slot 222 by means of a clamping plate 24 and bolts, thus achieving the snap-fit ​​installation of the support column 23.

[0058] Optionally, such as Figure 1 and Figure 2 As shown, the welding device also includes a base 30, a welding station 10 is rotatably connected to the base 30 about the first direction X, a plurality of first slag leakage holes 11 are arranged at intervals about the first direction X, a plurality of support members 20 are arranged at intervals about the first direction X, and each second slag leakage hole 21 is connected to a first slag leakage hole 11.

[0059] In this embodiment, the welding station 10 is rotatable relative to the base 30. Multiple welding positions can be provided on the welding station 10, each welding position having a first slag-removing hole 11. Multiple support members 20 are present, and each support member 20 has a second slag-removing hole 21 connected to a first slag-removing hole 11, thereby forming multiple slag-removing channels spaced apart around a first direction X. In this way, multiple welding positions are formed on the welding station 10, and each welding position can automatically remove slag through its corresponding slag-removing channel.

[0060] Specifically, such as Figure 1 and Figure 2 As shown, the welding station 10 is rotatably connected to the base 30 about the first direction X. Specifically, a driving component (such as a motor) can be installed on the base 30, and the driving component is driven to the welding station 10 to realize the rotation of the welding station 10. There are multiple first slag leakage holes 11 on the welding station 10, and the multiple first slag leakage holes 11 are arranged at intervals about the first direction X. There are also multiple support members 20, and the multiple support members 20 are arranged at intervals about the first direction X. Each second slag leakage hole 21 is connected to a first slag leakage hole 11, thereby forming multiple slag leakage channels, which can correspond to the situation where multiple welding stations are set on the welding station 10.

[0061] For example, the number of welding stations and the number of first slag leakage holes 11 on the welding station 10 are both four. The four welding stations and the four first slag leakage holes 11 are evenly distributed on the welding station 10 around the first direction X. The welding station is changed every time the welding station 10 rotates 90 degrees. Of course, the number of welding stations and the number of first slag leakage holes 11 can be flexibly set according to the actual situation, and this application embodiment does not limit this.

[0062] Optionally, such as Figure 2 and Figure 5 As shown, the welding apparatus also includes a slag suction assembly 40, which includes a storage container 41 and a slag suction pipe 42. The storage container 41 is adapted to be connected to a first negative pressure device (not shown in the figure) to generate a negative pressure in the storage container 41. The slag suction pipe 42 is connected to the storage container 41, and one end of the slag suction pipe 42 away from the storage container 41 is connected to a first slag leakage hole 11.

[0063] In this embodiment, the first negative pressure device can create a negative pressure environment in the storage container 41, thereby creating a negative pressure in the slag suction pipe 42, so that the end of the slag suction pipe 42 away from the storage container 41 can suck up the welding slag in the first slag leakage hole 11, thereby better cleaning the welding slag, improving the cleaning effect of the welding slag, and also reducing the probability of welding slag blockage.

[0064] Specifically, such as Figure 2 and Figure 5As shown, the slag suction assembly 40 includes a storage container 41 and a slag suction pipe 42. The storage container 41 is a component for storing welding slag, and the slag suction pipe 42 is a component for sucking welding slag from the first slag leakage hole 11. The storage container 41 is connected to the first negative pressure device, and a negative pressure environment is formed in the storage container 41, so that the welding slag can be sucked out through the slag suction pipe 42.

[0065] For example, the first negative pressure device can be a vacuum generator, a fan, or other components capable of creating a negative pressure environment. Of course, the specific type of the first negative pressure device can be flexibly selected according to the actual situation, and this application embodiment does not limit this.

[0066] Optionally, such as Figure 2 and Figure 5 As shown, the slag suction assembly 40 also includes a connecting pipe 43 and a sealing ring gasket 44. The connecting pipe 43 is located at the end of the slag suction pipe 42 away from the storage container 41 and is connected to the slag suction pipe 42. The connecting pipe 43 is connected to the first slag leakage hole 11. The sealing ring gasket 44 is located between the connecting pipe 43 and the welding station 10 and is used to seal the gap between the connecting pipe 43 and the welding station 10.

[0067] In the embodiments of this application, such as Figure 5 As shown, a connecting pipe 43 is connected to the slag suction pipe 42. The outer diameter of the connecting pipe 43 is larger than that of the slag suction pipe 42, giving the end of the connecting pipe 43 a larger mounting surface. A sealing ring gasket 44 is provided between the connecting pipe 43 and the welding station 10. The sealing ring gasket 44 is installed on the mounting surface of the connecting pipe 43. When the sealing ring gasket 44 abuts against the welding station 10, it can seal the gap between the connecting pipe 43 and the welding station 10. This reduces the probability of welding slag falling outside and improves the suction effect of welding slag in the first slag leakage hole 11.

[0068] Specifically, such as Figure 5 As shown, the connecting pipe 43 is located at the end of the slag suction pipe 42 away from the storage container 41 and communicates with the slag suction pipe 42. The sealing ring gasket 44 is located at the end of the connecting pipe 43 facing the welding station 10. The sealing ring gasket 44 can be made of a soft material, allowing the connecting pipe 43 to compress the sealing ring gasket 44, causing the sealing ring gasket 44 to deform to better seal the gap between the connecting pipe 43 and the welding station 10. For example, the sealing ring gasket 44 can be made of foamed silicone material. Of course, the specific material of the sealing ring gasket 44 can be flexibly selected according to the actual situation, and this embodiment does not limit it.

[0069] Optionally, such as Figure 1 and Figure 5As shown, the welding device also includes a displacement component 50, which has a second direction Y, perpendicular to the first direction X. The displacement component 50 includes a first driving member 51 and a second driving member 52. The second driving member 52 is disposed on one side of the base 30, and the first driving member 51 is disposed on the second driving member 52. The slag suction pipe 42 is disposed on the first driving member 51. The second driving member 52 can drive the first driving member 51 to move along the second direction Y, and the first driving member 51 can drive the slag suction pipe 42 to move along the first direction X.

[0070] It should be noted that the first direction X and the second direction Y are perpendicular, which can be strictly "perpendicular," for example, the angle between the first direction X and the second direction Y is 90°; or it can be "approximately perpendicular," specifically meaning that the angle between the first direction X and the second direction Y includes a certain error, taking into account the measurement and the error associated with the measurement of a specific quantity (i.e., the limitation of the measurement system), the error is within the acceptable deviation range for a specific value as determined by a person skilled in the art; for example, the angle between the first direction X and the second direction Y is 90°±5°.

[0071] In this embodiment of the application, by installing the slag suction pipe 42 onto the first driving member 51 and the first driving member 51 onto the second driving member 52, the slag suction pipe 42 can be driven along the first direction X and the second direction Y, so that the slag suction pipe 42 can approach and move away from the welding station 10 along the first direction X and the second direction Y, so that the welding slag pipe can avoid the rotating welding station 10 and avoid collision between the welding slag pipe and the welding station 10.

[0072] Specifically, such as Figure 1 and Figure 5 As shown, the displacement component 50 includes a first driving member 51 and a second driving member 52. The second driving member 52 is located on one side of the base 30, specifically on the side of the base 30 close to the slag suction component 40. The first driving member 51 is located on the second driving member 52, and the slag suction tube 42 is located on the first driving member 51, thereby enabling the slag suction tube 42 to be driven along the first direction X and the second direction Y.

[0073] For example, the first driving member 51 and the second driving member 52 can be components that achieve linear drive, such as cylinders or electric push rods. Of course, the specific types of the first driving member 51 and the second driving member 52 can be flexibly selected according to the actual situation, and the embodiments of this application do not limit this.

[0074] It should be noted that the storage container 41 can be fixed on the ground, and the slag suction pipe 42 can be a metal pipe. The slag suction pipe 42 is connected to the storage container 41 through a corrugated hose, so that the corrugated hose can adapt to the driving of the first driving member 51 and the second driving member 52, and the position of the slag suction pipe 42 can be easily changed.

[0075] Optionally, such as Figure 1 and Figure 6 As shown, the welding apparatus includes a fumigation assembly 60, which includes a fumigation tube 61 and a support 63. The support 63 is located on one side of the base 30, and the fumigation tube 61 is located on the support 63. The fumigation tube 61 is adapted to communicate with a second negative pressure device (not shown in the figure) to generate negative pressure in the fumigation tube 61. One end of the fumigation tube 61 faces the support member 20 to absorb the fumes generated during welding.

[0076] In this embodiment, the second negative pressure device can generate a negative pressure environment within the fumigation tube 61, thereby enabling the fumigation tube 61 to have a suction effect and to extract the fumes generated during the welding process. For example, during laser welding, the fumes near the support member 20 can be extracted, reducing the impact of the fumes on the laser, improving the welding effect, and reducing the probability of defects such as incomplete or insufficient welding.

[0077] Specifically, such as Figure 1 and Figure 6 As shown, the bracket 63 can be positioned on the side of the base 30 closer to the welding mechanism, allowing the smoke extraction tube 61 on the bracket 63 to be closer to the welding position, resulting in better smoke extraction. Furthermore, the bracket 63 can be configured as an adjustable structure, allowing for adjustment of the position of the smoke extraction tube 61 to suit different smoke extraction conditions.

[0078] For example, the second negative pressure device can be a vacuum generator, a fan, or other components capable of creating a negative pressure environment. Of course, the specific type of the second negative pressure device can be flexibly selected according to the actual situation, and this application embodiment does not limit this.

[0079] Optionally, such as Figure 6 As shown, the smoking assembly 60 also includes a smoking hood 62, which has a first end 621, a second end 622, and a channel 623 connecting the first end 621 and the second end 622. The first end 621 is connected to the end of the smoking tube 61 near the support member 20, and the channel 623 is connected to the smoking tube 61. The cross-sectional area of ​​the channel 623 gradually increases from the first end 621 to the second end 622.

[0080] In this embodiment, the smoking hood 62 has a larger smoking area than the smoking tube 61, thus improving the smoking effect. Furthermore, the cross-sectional area of ​​the channel 623 gradually increases from the first end 621 to the second end 622, making the entire smoking hood 62 trumpet-shaped, further enhancing the smoking effect.

[0081] Specifically, such as Figure 6 As shown, the fume hood 62 is trumpet-shaped, with the larger end of the fume hood 62 closer to the workpiece, so as to better absorb the fumes generated during the welding process.
