Abstract

This application discloses a welding nozzle protective cover transfer module and welding equipment, including a support, a receiving box, and a transfer mechanism. The support includes a base and a support arm. The support arm is located on one side of the base and connected to the base, serving to receive the welding nozzle protective cover. The receiving box is mounted on the base. The transfer mechanism is driven by the support and can drive the support to move back and forth between a first position and a second position. When the support receives the welding nozzle protective cover via the support arm, the receiving box is located directly below the welding nozzle protective cover in the vertical direction, serving to receive welding slag that falls off the inner wall of the welding nozzle protective cover. By setting a receiving box on the support and using the receiving box to receive welding slag that falls off the welding nozzle protective cover during transfer, this application prevents welding slag from falling off the support, thus preventing contamination problems caused by welding slag adhering to the welding nozzle protective cover falling off, and reducing the workload of subsequent cleaning of the welding equipment using this welding nozzle protective cover transfer module.

Description

Technical Field

[0001] This utility model belongs to the technical field of welding nozzle protective cover replacement, and in particular relates to a welding nozzle protective cover transfer module and welding equipment. Background Technology

[0002] During laser welding, a welding nozzle protective cover is installed on the outside of the welding nozzle, primarily to block welding spatter (such as weld slag and metal particles), preventing these spatter from adhering to the welding nozzle or laser lens, thereby ensuring welding quality and equipment stability. Because the welding nozzle protective cover is in prolonged contact with high-temperature molten metal spatter, weld slag gradually accumulates on its inner wall, leading to a decrease in its protective performance. Therefore, the welding nozzle protective cover needs to be replaced periodically.

[0003] In the lithium-ion battery cell production and assembly process, existing laser welding equipment requires a support to hold the protective cover at the nozzle's location before transferring it to the target position for replacement by a robotic arm. Because welding slag accumulates on the inner wall of the protective cover, this slag can easily detach and fall onto the support during transport. This detached slag not only rolls and scatters on the support surface but also directly falls onto the battery cells, fixtures, and critical parts of the laser welding equipment. This poses a serious risk of product contamination, affecting battery cell quality and safety, and significantly increases the difficulty and workload of equipment cleaning and maintenance, negatively impacting production efficiency and product yield. Utility Model Content

[0004] In view of this, it is necessary to provide a welding nozzle protective cover transfer module and welding equipment for solving the above-mentioned technical problems.

[0005] A welding nozzle protective cover transfer module is used to receive the welding nozzle protective cover and drive the welding nozzle protective cover to switch back and forth between a first position and a second position; the welding nozzle protective cover transfer module includes:

[0006] The support includes a base and a support arm, wherein the support arm is disposed on one side of the base and connected to the base, and is used to support the welding nozzle protective cover;

[0007] A receiving box is installed on the substrate;

[0008] A transfer mechanism is connected to the support in a transmission manner, and the transfer mechanism is capable of driving the support to move back and forth between the first position and the second position;

[0009] When the support receives the welding nozzle protective cover via the support arm, the receiving box is positioned directly below the welding nozzle protective cover in the vertical direction to receive welding slag that falls off from the inner wall of the welding nozzle protective cover.

[0010] Understandably, by setting a receiving box on the support and using the receiving box to catch the welding slag that falls off the welding nozzle protective cover during the transfer process, the welding slag is prevented from falling off the support. This can prevent pollution problems caused by the welding slag adhering to the welding nozzle protective cover falling off, and reduce the workload of cleaning the welding equipment using the welding nozzle protective cover transfer module.

[0011] In one embodiment, the receiving box is detachably connected to the substrate.

[0012] Understandably, the detachable connection between the receiving box and the base allows users to remove the receiving box from the base to clean the welding slag inside the receiving box, which facilitates subsequent cleaning of the welding slag inside the receiving box.

[0013] In one embodiment, the receiving box is covered with an adhesive backing, and the substrate is able to support the receiving box through the adhesive backing.

[0014] Understandably, the material properties of the adhesive backing can be used to dampen shocks and cushion the assembly of the receiving box onto the substrate. On the other hand, the elastic deformation of the adhesive backing can be used to facilitate the removal of the receiving box from the substrate.

[0015] In one embodiment, the receiving box is at least partially embedded in the substrate.

[0016] Understandably, embedding the receiving box into the base body can reduce the impact of the receiving box assembly on the support on the overall height of the support, and facilitate the assembly of the receiving box onto the base body.

[0017] In one embodiment, the receiving box is configured as a non-metallic box.

[0018] Understandably, using a non-metallic receiving box not only avoids hard collisions and wear between the receiving box and the welding nozzle protective cover, but also facilitates the subsequent replacement of the receiving box on the support.

[0019] In one embodiment, the receiving box includes a peripheral wall for abutting and limiting the contact with the welding nozzle protective cover.

[0020] Understandably, by using the contact limit between the peripheral wall of the receiving box and the welding nozzle protective cover, the welding nozzle protective cover can be prevented from shaking when it moves with the support. This not only improves the stability of the support when it receives the welding nozzle protective cover, but also allows the welding slag that falls off the welding nozzle protective cover to be completely received by the receiving box.

[0021] In one embodiment, the peripheral wall can be partially overlapped with the welding nozzle protective cover in the vertical direction.

[0022] In one embodiment, the number of the support arms is configured to be two, with the two support arms disposed at both ends of the base, and the two support arms together serve to support the welding nozzle protective cover.

[0023] It is understandable that using two support arms to jointly support the welding nozzle protective cover allows the support to simplify its structure while fulfilling its function of supporting the welding nozzle protective cover.

[0024] In one embodiment, the support arm and the base are connected as an integral structure.

[0025] It is understandable that connecting the support arm to the base as a whole allows the support to be cast in one piece, which facilitates the production and manufacturing of the support.

[0026] This application also provides a welding device, including the welding nozzle protective cover transfer module described above.

[0027] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0028] The welding nozzle protective cover transfer module and welding equipment claimed in this application, by setting a receiving box on the support and using the receiving box to receive the welding slag that falls off the welding nozzle protective cover during the transfer process, can prevent the welding slag from falling off the support. This can prevent the pollution problem caused by the falling of welding slag adhering to the welding nozzle protective cover and reduce the workload of subsequent cleaning of the welding equipment using the welding nozzle protective cover transfer module.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] The welding nozzle protective cover transfer module 100 claimed in this application is used to receive the welding nozzle protective cover 200 and to move the welding nozzle protective cover back and forth between a first position (not shown) and a second position (not shown), thereby achieving the purpose of transferring the welding nozzle protective cover 200. Here, the first position is specifically the position of the welding nozzle protective cover 200 on the welding nozzle (not shown); the second position is the position when the robotic arm changes the welding nozzle protective cover 200 on the welding nozzle protective cover transfer module 100. It can be understood that the above-mentioned first position and second position can be interchanged as needed, which will not be elaborated here.

[0037] like Figure 1 , Figure 2As shown, the welding nozzle protective cover transfer module 100 provided in this application includes a support 10, a receiving box 20, and a transfer mechanism 30. The support 10 includes a base 11 and a support arm 12. The support arm 12 is disposed on one side of the base 11 and connected to the base 11, and is used to receive the welding nozzle protective cover 200. The receiving box 20 is installed on the base 11. The transfer mechanism 30 is connected to the support 10 in a transmission manner, and the transfer mechanism 30 can drive the support 10 to move back and forth between a first position and a second position. When the support 10 receives the welding nozzle protective cover 200 through the support arm 12, the receiving box 20 is disposed directly below the welding nozzle protective cover 200 in the vertical direction, and is used to receive the welding slag that falls off from the inner wall of the welding nozzle protective cover 200. It is understood that the welding nozzle protective cover transfer module 100 of this application sets a receiving box 20 on the support 10 and uses the receiving box 20 to receive the welding slag that falls off the welding nozzle protective cover 200 during the transfer process, so as to prevent the welding slag from falling off the support 10. This can prevent the pollution problem caused by the welding slag adhering to the welding nozzle protective cover 200 falling off, and reduce the workload of cleaning the welding equipment using the welding nozzle protective cover transfer module 100.

[0038] like Figure 2 As shown, in one embodiment, the number of support arms 12 is configured as two, with the two support arms 12 disposed at both ends of the base 11, and the two support arms 12 jointly support the welding nozzle protective cover 200. That is, the support 10 of this embodiment can use two support arms 12 to jointly support the welding nozzle protective cover 200, thus simplifying the structure of the support 10 while fulfilling the function of supporting the welding nozzle protective cover 200. It is understood that in other embodiments, the number of support arms 12 may also be configured as three, four, or even more, or the support arm 12 may be configured as a single ring; these will not be elaborated upon here.

[0039] like Figure 2 As shown, in this embodiment, each support arm 12 is provided with a limiting groove 121. Specifically, the limiting groove 121 can be configured as an arc-shaped groove. The limiting groove 121 is used to match the protrusion (not shown) of the welding nozzle protective cover 200. When the support 10 moves to the first position under the drive of the transfer mechanism 30, the support arm 12 on the support 10 can be limited by the abutment between the groove wall of the limiting groove 121 and the corresponding protrusion on the welding nozzle protective cover 200, so that the support 10 supports the welding nozzle protective cover 200. Then the welding nozzle protective cover 200 is released by the fixing structure fixed to the welding nozzle. In this way, the welding nozzle protective cover 200 can be transferred to the support arm 12 of the support 10 under the action of gravity, and the support 10 can receive the welding nozzle protective cover 200.

[0040] In one embodiment, the support arm 12 and the base 11 are connected as an integral structure, allowing the support 10 to be integrally cast, which facilitates the production of the support 10. Here, the material of the support 10 can be configured as a conventional metal material in the prior art.

[0041] In one embodiment, the receiving box 20 is detachably connected to the base 11, allowing the user to remove the receiving box 20 from the base 11 to clean the welding slag inside the receiving box 20, which facilitates subsequent cleaning of the welding slag inside the receiving box 20.

[0042] In one embodiment, an adhesive backing pad (not shown) is attached to the receiving box 20, and the substrate 11 can support the receiving box 20 through the adhesive backing pad, so that the receiving box 20 can be shock-absorbing and buffered when it is assembled on the substrate 11. In addition, the elastic deformation material properties of the adhesive backing pad can be used to facilitate the removal of the receiving box 20 from the substrate 11, thereby facilitating the replacement of the receiving box 20.

[0043] like Figure 1 , Figure 2 As shown, in one embodiment, the receiving box 20 is at least partially embedded within the base 11, thereby enabling the assembly of the receiving box 20 onto the base 11 and achieving the purpose of detachable connection of the receiving box 20 to the base 11. Because the receiving box 20 is embedded within the base 11, the impact of the assembly of the receiving box 20 on the support 10 on the overall height of the support 10 is reduced, and it facilitates the assembly of the receiving box 20 onto the base 11. Here, the receiving box 20 is entirely embedded within the base 11.

[0044] like Figure 2 As shown, in one embodiment, the receiving box 20 includes a peripheral wall 21, which is used to abut and limit the welding nozzle protective cover 200. This can realize the assembly limitation of the receiving box 20 on the support 10, and prevent the welding nozzle protective cover 200 from shaking when it moves back and forth between the first position and the second position with the support 10. This not only improves the stability of the support 10 when it receives the welding nozzle protective cover 200, but also allows the welding slag that falls off the welding nozzle protective cover 200 to be completely received by the receiving box 20.

[0045] like Figure 1 As shown, in this embodiment, the peripheral wall 21 can partially overlap with the welding nozzle protective cover 200 in the vertical direction Z. That is, when the support arm 12 on the support 10 receives the welding nozzle protective cover 200, the welding nozzle protective cover 200 is partially inserted into the receiving box 20. In this way, the positional interference between the welding nozzle protective cover 200 and the receiving box 20 can be used to achieve the abutment and limiting between the peripheral wall 21 of the receiving box 20 and the welding nozzle protective cover 200.

[0046] In one embodiment, the receiving box 20 is configured as a non-metallic box, meaning that the receiving box 20 can be manufactured from a non-metallic material. This not only avoids hard contact and wear between the receiving box 20 and the welding nozzle protective cover 200, but also facilitates subsequent replacement of the receiving box 20 on the support 10. Specifically, the material of the receiving box 20 can be configured as high-temperature resistant nylon, ceramic, quartz glass, etc.

[0047] like Figure 1 As shown, in one embodiment, the transfer mechanism 30 can drive the support 10 to rotate, lift, extend, and laterally move when it is working, thereby enabling the transfer mechanism 30 to move the support 10 back and forth between the first position and the second position. Here, the rotation of the support 10 by the transfer mechanism 30 is to facilitate the subsequent replacement of the welding nozzle protective cover 200 on the support 10 by a robotic arm, so as to avoid positional interference between the robotic arm and other components in the welding equipment when replacing the welding nozzle protective cover 200. It should be noted that the specific structure and working principle of how the transfer mechanism 30 drives the support 10 to move when it is working can adopt existing conventional methods, and will not be elaborated here.

[0048] In addition, this application also provides a welding device, including the aforementioned welding nozzle protective cover transfer module 100. Specifically, this welding device can be used to weld the tabs to the battery cover plate during the lithium-ion cell production and assembly process. It is understood that in other embodiments, this welding device can also be applied to welding other products, which will not be elaborated upon here.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
