Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and in particular relates to a switching piece welding device. Background Art

[0002] During battery manufacturing, adapters are typically welded to the terminals on the battery's top cover. This allows for electrical connection between the battery's tabs and the terminals on the top cover, enabling the input and output of electrical energy within the battery. Currently, laser welding is commonly used to secure the adapters to the battery's top cover. During welding, dust removal devices are typically installed to remove welding slag and prevent it from affecting weld quality.

[0003] In the prior art CN218136063U, a welding clamping device is provided with a vacuum pipe to apply negative pressure to the pressure head, so that the welding slag and dust generated by welding can be sucked out of the welding clamping device, thereby maintaining a clean welding environment and improving welding quality. However, in actual application, the vacuum pipe cannot completely remove the welding slag. Some of the welding slag will splash through the inner cavity of the pressure head onto the laser light output lens, causing the light output lens to be dirty, requiring frequent replacement and cleaning.

[0041] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0042] In the description of this application, it should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0043] Example 1:

[0044] This embodiment provides an adapter plate welding device, including:

[0045] A substrate 1 is provided with a laser channel 11 for the welding laser to pass through;

[0046] The connecting base 2 is mounted on the substrate 1 and is used to connect to the laser. The connecting base 2 is provided with a light inlet channel 21, which is connected to the laser channel 11;

[0047] The protective sheet 3 is detachably mounted on the connecting base 2 and is provided with a light inlet 31;

[0048] The pressing head assembly 4 is mounted on the substrate 1 for pressing the adapter, and the pressing head assembly 4 includes a light output channel 41, which is connected to the laser channel 11;

[0049] The first dust removal mechanism is installed on the substrate 1 and is connected to the light output channel 41, and is used to absorb welding slag generated by welding.

[0050] In the present technical solution, the connecting seat 2 and the pressure head assembly 4 can be installed on the substrate 1 by setting fasteners, or can be connected to the substrate 1 as a whole. When the adapter welding device is in use, the pressure head assembly 4 abuts against the adapter to be welded, pressing the adapter onto the battery top cover, and the connecting seat 2 is connected to the light output lens of the laser. The laser emitted by the laser first passes through the light inlet 31 of the protective plate 3, then passes through the laser channel 11, and then is emitted from the light output channel 41 to weld the adapter. It should be noted that the light output size of the laser is adjusted and set according to the number and area of ​​the weld prints, and the light inlet 31 of the protective plate 3 is set according to the light output size of the laser, ensuring that the size of the light inlet 31 of the protective plate 3 is compatible with the light output size of the laser.

[0051] During the welding process, the welding slag generated will splash onto the laser's light output lens along the light output channel 41, laser channel 11, and light input channel 21 in sequence. A protective sheet 3 is provided at the light input channel 21 of the connector 2. The light input hole 31 of the protective sheet 3 is adapted to the size of the laser's light output, which not only ensures that the laser can effectively weld the adapter, but also isolates the splashing welding slag, preventing the laser lens from being contaminated, and effectively extending the lens's service life. In addition, the protective sheet 3 is detachably connected to the connector 2, and the protective sheet 3 can be removed to clean the welding slag remaining on the protective sheet 3, so that the protective sheet 3 can be recycled, reducing production costs and improving economic benefits.

[0052] A first dust removal mechanism connected to the light output channel 41 is also provided on the substrate 1. The first dust removal mechanism can absorb the welding slag generated by welding to ensure the cleanliness of the welding part of the adapter plate, thereby improving the welding quality; it can also reduce the welding slag splashing onto the protective plate 3, effectively extending the service life of the protective plate 3, and is highly practical.

[0053] In addition, the first dust removal mechanism is connected to the light output channel 41 of the pressure head assembly 4, and the light output channel 41 is close to the welding position of the adapter plate. Therefore, the first dust removal mechanism can directly absorb the welding slag generated at the welding position, thereby reducing the amount of welding slag splashing toward the side of the protective plate 3.

[0054] Example 2:

[0055] This embodiment provides an adapter plate welding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0056] Furthermore, the connecting seat 2 also includes:

[0057] The protective sheet 3 is detachably installed in the slot 22 and is locked on the connecting base 2 by a fastener.

[0058] In this technical solution, the slot 22 is a "cross" structure and is arranged to penetrate the connecting base 2 along the first direction X and the second direction Y. Two notches are formed on both sides of the connecting base 2 along the first direction X and the second direction Y, respectively. The protective sheet 3 can be directly inserted into the slot 22 of the connecting base 2 through either notch. Then, a hexagonal bolt is provided on the top of the connecting base 2, and the hexagonal bolt is used to tighten the protective sheet 3 and the connecting base 2, thereby achieving a detachable connection between the protective sheet 3 and the connecting base 2. This structural design makes installation and removal of the protective sheet 3 and the connecting base 2 more convenient, effectively improving work efficiency and high practicality.

[0059] Example 3:

[0060] This embodiment provides an adapter plate welding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] Furthermore, a pressing mark 23 is provided on the connecting seat 2, and an identification arrow 32 is provided on the protective sheet 3;

[0062] When the protective sheet 3 is installed in the slot 22 , the marking arrow 32 is aligned with the pressing mark 23 .

[0063] In the present technical solution, the clamping mark 23 can be a scale line. Two scale lines are set at the top of the connecting seat 2 along the third direction Z, one scale line is set along the first direction X, and the other scale line is set along the second direction Y. There are two identification arrows 32 at the top of the protective sheet 3 along the third direction Z, pointing to the first direction X and the second direction Y respectively. The protective sheet 3 is installed in the slot 22 of the connecting seat 2. When the two identification arrows 32 point to the zero scale position of the two scale lines respectively, it indicates that the protective sheet 3 is installed in the center position of the slot 22.

[0064] Through this structural design, when the protective sheet 3 is removed for cleaning and then reinstalled, the identification arrow 32 and the compression mark 23 are aligned so that the protective sheet 3 can be quickly installed in the center position of the slot 22, effectively improving the installation efficiency of the protective sheet 3.

[0065] Example 4:

[0066] This embodiment provides an adapter plate welding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0067] In this technical solution, a dust suction channel 44 is provided on one side of the pressure head assembly 4. The dust suction channel 44 is connected to the light outlet channel 41. The first dust removal mechanism removes welding slag through the dust suction channel 44. In this technical solution, the dust suction channel 44 provided on the side of the pressure head assembly 4 guides the welding slag from the side of the pressure head assembly 4 to be sucked away by the first dust suction mechanism under the action of negative pressure. The dust suction channel 44 located on the side does not interfere with other mechanisms, maximizing the use of redundant space in the welding device.

[0068] Furthermore, the pressure head assembly 4 includes:

[0069] The fixing seat 42 is installed on the substrate 1, and the light output channel 41 is arranged along the third direction Z through the fixing seat;

[0070] The welding pressure head 43 can be detachably mounted on the fixing seat 42 along the first direction X. The fixing seat 42 and the welding pressure head 43 jointly define a dust suction channel 44. The welding pressure head 43 is also provided with a light outlet.

[0071] Among them, for different models of adapters, they need to adapt to the corresponding welding pressure head 43 to meet the welding requirements. When changing the production model, it is only necessary to remove the welding pressure head 43 from the fixing seat 42 and replace it with a new welding pressure head 43 to complete the replacement of the welding device, thereby improving the compatibility of the welding device.

[0072] Furthermore, the fixing seat 42 includes:

[0073] A first groove is provided on a side of the fixing seat 42 close to the welding pressure head 43;

[0074] The welding head 43 comprises:

[0075] A second groove is provided on a side of the welding pressure head 43 close to the fixing seat 42;

[0076] When the welding pressure head is installed and connected to the fixing seat, the first groove and the second groove form a dust suction channel 44.

[0077] A first groove is provided on the end surface of the fixing seat 42 close to the welding pressure head 43, and a second groove is provided on the end surface of the welding pressure head 43 close to the fixing seat 42. When the welding pressure head 43 is installed on the fixing seat 42, the first groove and the second groove are arranged opposite to each other to form a dust suction channel 44. The output end of the first dust removal mechanism is connected to the dust suction channel 44 to remove the welding slag generated by welding.

[0082] A first dust suction pipe 6 is mounted on the connecting plate 5 and communicates with the through hole 51;

[0083] A driving member 7 is mounted on the base plate 1 and is used to control the connecting plate 5 to abut against the pressure head assembly 4 along the first direction X;

[0084] When the connecting plate 5 abuts against the pressure head assembly 4 along the first direction X, the dust suction channel 44 and the through hole 51 are connected.

[0085] Furthermore, the substrate 1 further comprises:

[0086] The connecting plate 5 is movably disposed in the guide area 12 along the first direction X.

[0087] Furthermore, the driving member 7 is a cylinder.

[0088] In this technical solution, the cylinder is installed on the base plate 1, the connecting plate 5 is arranged in the guide area 12 and connected to the output end of the cylinder, and the first dust suction pipe 6 is installed on one side of the connecting plate 5 by setting fasteners. After the welding pressure head 43 is installed on the fixed seat 42, the cylinder controls the connecting plate 5 to move along the first direction X in the guide area 12, so that the other side of the connecting plate 5 abuts the end of the fixed seat 42 and the welding pressure head 43, and the first dust suction pipe 6, the through hole 51 and the dust suction channel 44 are connected in sequence. The first dust suction pipe 6 is connected to the external negative pressure device to achieve the function of sucking away the welding slag generated during welding.

[0089] At the same time, the two ends of the welding pressure head 43 along the first direction X respectively abut the inner wall of the slide groove of the fixed seat 42 and the connecting plate 5, which can limit the welding pressure head 43 and ensure that the welding pressure head 43 can be fixedly installed on the fixed seat 42, thereby eliminating the need for additional fasteners for locking connection, which helps to achieve rapid disassembly and assembly of the welding pressure head 43 and is highly practical.

[0090] Example 6:

[0094] In this technical solution, the connector 52 can be a pin, which is installed on one side of the connecting plate 5 close to the fixing seat 42. When the cylinder drives the connecting plate 5 to abut the welding pressure head 43 along the first direction X, the pin is plugged into the socket 45 on the fixing seat 42, thereby effectively enhancing the connection stability between the connecting plate 5 and the fixing seat 42.

[0095] In other alternative embodiments, the socket 45 is provided on the welding head 43 .
