Description

Technical Field

[0001] This application relates to the field of welding technology, and in particular to a welding apparatus and battery production equipment. Background Technology

[0002] Welding technology is a commonly used technology in industrial production processes. Common applications of welding technology include, for example, the production process of batteries. Types of welding include arc welding and laser welding. Common laser welding can achieve the welding operation by sending a laser beam through an optical fiber to a galvanometer, and then projecting the laser beam through the galvanometer.

[0003] Laser welding equipment may experience temperature drift and incomplete welding during production and use, requiring maintenance of the welding equipment. However, existing welding equipment has problems such as easy contamination of the galvanometer during maintenance. Utility Model Content

[0004] The main purpose of this application is to provide a welding device and battery production equipment, which aims to solve the technical problems of easy contamination of the galvanometer during the maintenance of existing welding devices.

[0005] To address the aforementioned problems, this application provides a welding apparatus comprising a first mounting component, a second mounting component, a galvanometer assembly, an optical fiber protection assembly, and a rotating component. The galvanometer assembly is connected to the first mounting component and is used to project a welding laser. The optical fiber protection assembly is connected to the first mounting component and is used to guide the optical fiber to connect with the galvanometer assembly. The optical fiber protection assembly has an optical fiber inlet. The rotating component is connected to the first mounting component and the second mounting component. The rotating component is configured such that the first mounting component drives the galvanometer assembly and the optical fiber protection assembly to rotate relative to the second mounting component, thereby changing the position of the optical fiber inlet.

[0006] In the above embodiments, the optical fiber protection component has an optical fiber inlet. The optical fiber protection component is used to guide the connection between the optical fiber and the galvanometer component, so as to fix the optical fiber through the optical fiber protection component and simplify the assembly difficulty of the welding device. The galvanometer component is used to project the welding laser, so that the welding device can perform welding operations by emitting the laser through the optical fiber and the galvanometer component. The galvanometer component and the optical fiber protection component are connected to the first mounting component. The rotating component is connected to the first mounting component and the second mounting component. The rotating component is configured such that the first mounting component drives the galvanometer component and the optical fiber protection component to rotate relative to the second mounting component. This allows the rotating component to drive the first mounting component and the second mounting component to rotate relative to each other, changing the position of the optical fiber inlet. This, in turn, drives the optical fiber protection component and the galvanometer component to rotate to a specific position that is conducive to the insertion and removal of the optical fiber, reducing the maintenance difficulty and contamination risk of the welding device. At the same time, it can also shorten the maintenance time of the welding device and improve the welding efficiency.

[0007] In some embodiments, the first mounting member has a first side and a second side disposed opposite to each other, and the galvanometer assembly and the fiber optic protection assembly are connected to the first side; the second mounting member has a third side facing the second side; the rotating member is configured such that the first mounting member rotates relative to the second mounting member about a first direction, wherein the first direction is perpendicular to the third side.

[0008] In the above embodiments, the galvanometer assembly and the fiber protection assembly are connected to the first surface, and the second mounting member has a third surface facing the second surface, which reduces interference between the galvanometer assembly and the fiber protection assembly and facilitates welding operations by the welding device. The rotating member is configured to allow the first mounting member to rotate relative to the second mounting member around a first direction, which allows the first mounting member to rotate in a smaller space and improves the reliability of the rotation of the first mounting member.

[0009] In some embodiments, the rotating member is fixedly connected to the first mounting member and movably connected to the second mounting member. The rotating member is used to drive the first mounting member to rotate relative to the second mounting member about a first direction.

[0010] In the above embodiments, the rotating member is fixedly connected to the first mounting member and movably connected to the second mounting member, so as to connect the first mounting member and the second mounting member through the rotating member, and to drive the first mounting member to rotate relative to the second mounting member around the first direction through the rotating member, so that the first mounting member can rotate in a smaller space, thereby further improving the reliability of the rotation of the first mounting member.

[0011] In some embodiments, the rotating member includes a first shaft portion and a second shaft portion, which are connected. The first shaft portion extends along a first direction, and along a second direction perpendicular to the first direction, the size of the first shaft portion is smaller than the size of the second shaft portion. The second mounting member is provided with a first through hole, which includes a first hole segment and a second hole segment. The first hole segment connects the second hole segment and a third surface, and along the second direction, the diameter of the first hole segment is smaller than the diameter of the second hole segment. The first shaft portion passes through the first hole segment and is connected to the first mounting member, and the second shaft portion is disposed in the second hole segment.

[0012] In the above embodiment, along the second direction perpendicular to the first direction, the size of the first shaft portion is smaller than the size of the second shaft portion, and along the second direction, the diameter of the first hole segment is smaller than the diameter of the second hole segment. The first shaft portion passes through the first hole segment and is connected to the first mounting member, and the second shaft portion is disposed in the second hole segment so as to limit the installation of the rotating member through the first through hole, which is more conducive to the movable connection between the rotating member and the second mounting member and simplifies the installation difficulty of the rotating member.

[0013] In some embodiments, the first mounting member is provided with a second through hole, which penetrates the first surface and the second surface, and the second through hole and the first through hole correspond to each other in a first direction; the second shaft portion passes through the second through hole, and the rotating member includes a third shaft portion, which is located on the side of the first mounting member away from the second mounting member, and the third shaft portion is connected to the second shaft portion and the first mounting member.

[0014] In the above embodiment, the second shaft passes through the second through hole, and the third shaft is located on the side of the first mounting member away from the second mounting member, reducing interference between the third shaft and the second mounting member. The third shaft is connected to the second shaft and the first mounting member, so that the rotating member can be fixedly connected to the first mounting member through the third shaft, simplifying the installation difficulty of the rotating member.

[0015] In some embodiments, along the first direction, the length of the second shaft portion is greater than or equal to the sum of the length of the first hole segment and the length of the through hole.

[0016] In the above embodiments, along the first direction, the length of the second shaft portion is greater than the sum of the length of the first hole segment and the length of the through hole, which allows the first mounting member to form a gap with the second mounting member during the process of needing to rotate relative to the second mounting member, thereby reducing the interference of the second mounting member with the rotation of the first mounting member and improving the rotation efficiency of the first mounting member.

[0017] In some embodiments, the difference between the sum of the lengths and the length of the second shaft portion is greater than or equal to 1 mm and less than or equal to 2 mm.

[0018] In the above embodiments, the difference between the sum of the lengths and the length of the second shaft is greater than or equal to 1 mm and less than or equal to 2 mm. By setting an appropriate length difference, the compactness of the welding device can be improved while reducing the risk of the second mounting part interfering with the first mounting part.

[0019] In some embodiments, the first mounting member includes a main mounting portion and an assembly portion, a second through hole is disposed in the assembly portion, and the main mounting portion is provided with a third through hole extending along a first direction; the assembly portion includes a first part and a second part, and along a second direction, the size of the first part is smaller than the size of the second part, wherein the first part is disposed in the third through hole, the second part is located on the side of the main mounting portion away from the second mounting member, the second part is connected to the first part, and a third shaft portion is located on the side of the second part away from the first part.

[0020] In the above embodiment, the first part is disposed in the third through hole, the second part is located on the side of the main mounting part away from the second mounting part, the second part is connected to the first part, and the third shaft part is located on the side of the second part away from the first part. The assembly tolerance between the rotating part and the first mounting part can be reduced by the assembly part cooperating with the main mounting part, thereby improving the assembly accuracy of the welding device.

[0021] In some embodiments, along the second direction, the size of the second shaft portion is smaller than the diameter of the second hole segment.

[0022] In the above embodiment, along the second direction, the size of the second shaft portion is smaller than the diameter of the second hole segment, which reduces the interference of the second mounting member with the rotation of the first mounting member and improves the rotation efficiency of the first mounting member.

[0023] In some embodiments, the welding apparatus includes an auxiliary rotating rod connected to a first mounting member.

[0024] In the above embodiments, the auxiliary rotating rod is connected to the first mounting component, and the first mounting component can be rotated by the auxiliary rotating rod, thereby reducing the external force required to rotate the first mounting component and reducing the difficulty of rotating the first mounting component.

[0025] In some embodiments, the rotating member is configured to rotate the first mounting member relative to the second mounting member to switch the welding apparatus between an operating state and a maintenance state; the fiber optic protection component is connected to the fiber optic cable through the fiber optic inlet, and when the welding apparatus is in the maintenance state, the opening of the fiber optic inlet faces non-upstream along the direction of gravity.

[0026] In the above embodiments, the optical fiber protection component is connected to the optical fiber through the optical fiber inlet. When the welding device is under maintenance, the opening of the optical fiber inlet faces non-upstream along the direction of gravity, which facilitates the insertion and removal of optical fibers in the welding device and reduces the risk of contaminating the galvanometer during the insertion and removal of optical fibers.

[0027] In some embodiments, the welding apparatus includes a fixing member that is detachably connected to a first mounting member and a second mounting member when the welding apparatus is in operation.

[0028] In the above embodiments, when the welding device is in operation, the fixing member is detachably connected to the first mounting member and the second mounting member to maintain the relative fixation of the first mounting member and the second mounting member, thereby improving the reliability of the welding device during operation. Furthermore, the detachable connection of the fixing member to the first mounting member and the second mounting member facilitates the switching of the welding device from operation to maintenance.

[0029] In some embodiments, the welding apparatus includes a stop member, a first mounting member is provided with a fourth through hole, the stop member is connected to the first mounting member through the fourth through hole, wherein the stop member is used to stop a second mounting member, and the position of the stop member is adjustable along the direction toward the second mounting member.

[0030] In the above embodiment, the first mounting member is provided with a fourth through hole, and the abutment member is connected to the first mounting member through the fourth through hole. The abutment member is used to abut against the second mounting member. The position of the abutment member is adjustable along the direction toward the second mounting member. The distance between the first mounting member and the second mounting member can be changed by the abutment member abutting against the first mounting member, so as to facilitate the switching of the welding device from the working state to the maintenance state.

[0031] In some embodiments, the welding apparatus includes a locking member, a first mounting member having a first locking hole, and a second mounting member having a second locking hole; when the welding apparatus is in a maintenance state, the first locking hole and the second locking hole correspond to each other, and the locking member is simultaneously provided in the first locking hole and the second locking hole.

[0032] In the above embodiments, when the welding device is under maintenance, the first locking hole and the second locking hole correspond to each other, and the locking member is simultaneously provided in the first locking hole and the second locking hole, so that the welding device is kept under maintenance by the locking member cooperating with the first locking hole and the second locking hole, thereby reducing the difficulty of maintenance.

[0045] Welding technology is a commonly used technology in industrial production processes. Common applications of welding technology include, for example, the production process of batteries. Types of welding include arc welding and laser welding. Common laser welding can achieve the welding operation by sending a laser beam through an optical fiber to a galvanometer, and then projecting the laser beam through the galvanometer.

[0046] Laser welding equipment may experience temperature drift and incomplete welding during production and use, requiring maintenance of the welding equipment. However, existing welding equipment has problems such as easy contamination of the galvanometer during maintenance.

[0047] To address the technical problems existing in related technologies, this application provides a welding apparatus and a welding system. The welding apparatus includes a first mounting component, a second mounting component, a galvanometer assembly, an optical fiber protection assembly, and a rotating component. The galvanometer assembly is connected to the first mounting component and is used to project a welding laser. The optical fiber protection assembly is connected to the first mounting component and is used to guide the optical fiber to connect with the galvanometer assembly. The optical fiber protection assembly has an optical fiber inlet. The rotating component is connected to the first mounting component and the second mounting component. The rotating component is configured such that the first mounting component drives the galvanometer assembly and the optical fiber protection assembly to rotate relative to the second mounting component, thereby changing the position of the optical fiber inlet. The rotating component can drive the first mounting component and the second mounting component to rotate relative to each other, thereby driving the optical fiber protection assembly and the galvanometer assembly to rotate to a specific position that facilitates the insertion and removal of the optical fiber. This reduces the maintenance difficulty and contamination risk of the welding apparatus, while also shortening the maintenance time of the welding apparatus and improving welding efficiency.

[0048] Specifically, see Figure 1 and Figure 2 , Figure 1 This is a first structural schematic diagram of a welding apparatus in operation according to one or more embodiments of this application. Figure 2 This is a structural schematic diagram of a welding apparatus in a maintenance state according to one or more embodiments of this application.

[0049] This application provides a welding apparatus 1, which includes a first mounting member 10, a second mounting member 20, a galvanometer assembly 30, an optical fiber protection assembly 40, and a rotating member 50. The galvanometer assembly 30 is connected to the first mounting member 10 and is used to project a welding laser. The optical fiber protection assembly 40 is connected to the first mounting member 10 and is used to guide an optical fiber to connect with the galvanometer assembly 30. The optical fiber protection assembly 40 has an optical fiber inlet 41. The rotating member 50 is connected to the first mounting member 10 and the second mounting member 20. The rotating member 50 is configured such that the first mounting member 10 drives the galvanometer assembly 30 and the optical fiber protection assembly 40 to rotate relative to the second mounting member 20, thereby changing the position of the optical fiber inlet 41.

[0050] The shapes and structures of the first mounting member 10 and the second mounting member 20 can be set according to actual conditions. For example, at least part of the structure of the first mounting member 10 and the second mounting member 20 can be flat or the like. The second mounting member 20 can be mounted on other devices, such as a transmission device. The first mounting member 10 and the second mounting member 20 are connected, and the galvanometer assembly 30 and the fiber optic protection assembly 40 are connected to the first mounting member 10. The transmission device can then drive the first mounting member 10, the second mounting member 20, the galvanometer assembly 30, and the fiber optic protection assembly 40 to move.

[0051] Both the fiber optic protection assembly 40 and the galvanometer assembly 30 are connected to the first mounting member 10. For example, the fiber optic protection assembly 40 and the galvanometer assembly 30 can be located on the same side of the first mounting member 10, and the fiber optic protection assembly 40 and the galvanometer assembly 30 are spaced apart from each other. The fiber optic protection assembly 40 can be used to guide the fiber optic cable to connect with the galvanometer assembly 30, and the galvanometer assembly 30 is used to project the welding laser to a predetermined position to realize the laser welding operation. The galvanometer assembly 30 may include a collimating lens, a deflecting lens, a focusing lens, etc.

[0052] The fiber optic protection assembly 40 may have an internal channel for accommodating optical fibers. The optical fibers can be inserted into the fiber optic protection assembly 40 and can be used to transmit high-power laser light generated by the laser to the galvanometer assembly 30. The fiber optic inlet 41 can be understood as a port in the fiber optic protection assembly 40 for fiber optic insertion. Optical fibers can be inserted into the fiber optic protection assembly 40 through the fiber optic inlet 41. In some embodiments, the fiber optic protection assembly 40 may have an internal fiber optic guiding channel with a fiber optic inlet 41 and a fiber optic outlet. Optical fibers can be inserted through the fiber optic inlet 41 and exited from the fiber optic outlet along the fiber optic guiding channel to connect with the galvanometer assembly 30. Since the galvanometer assembly 30 moves according to the position of the target welding point during the welding process, the optical fibers may undergo deformation such as twisting or stretching during this movement, posing a risk of damage. Therefore, the fiber optic protection assembly 40 can protect the optical fibers.

[0053] During production and use, welding device 1 may experience temperature drift and incomplete welding. The entire optical path may be contaminated by checking the lenses in the galvanometer assembly 30 by plugging and unplugging the optical fiber. However, if the position of the optical fiber protection component 40 is not adjusted before plugging and unplugging the optical fiber, impurities may enter and contaminate the galvanometer assembly 30. If the galvanometer assembly 30 and / or the optical fiber protection component 40 are disassembled and the optical fiber is plugged and unplugged directly, the length of the optical fiber is required, and the overall maintenance process will be too complicated and time-consuming.

[0054] The first mounting member 10 and the second mounting member 20 are connected by a rotating member 50. The rotating member 50 is configured such that the first mounting member 10 drives the galvanometer assembly 30 and the fiber optic protection assembly 40 to rotate relative to the second mounting member 20, thereby changing the position of the fiber optic inlet 41. This allows the fiber optic protection assembly 40 and the galvanometer assembly 30 to rotate to a specific position that facilitates the insertion and removal of the fiber optic cable. Changing the position of the fiber optic inlet 41 can be understood as adjusting the fiber optic inlet 41 from a first position to a second position by rotation, wherein the opening orientation of the fiber optic inlet 41 in the first position is different from that in the second position. Figure 1 and Figure 2 As shown, Figure 1 The relative position of the first mounting member 10 with respect to the second mounting member 20 is different. Figure 2The relative positions of the first mounting member 10 and the second mounting member 20 in the middle, thereby causing Figure 1 The positions of the fiber optic protection component 40 and the galvanometer component 30 are different. Figure 2 The positions of the fiber optic protection assembly 40 and the galvanometer assembly 30. Understandably, Figure 1 The fiber optic inlet 41 is in the first position, with its opening facing... Figure 2 The optical fiber inlet 41 is in the second position, and its opening is horizontal. The shape and structure of the rotating member 50 can be set according to the actual situation. For example, the rotating member 50 can be spherical or cylindrical. The rotating member 50 can drive the first mounting member 10 to rotate relative to the second mounting member 20 in one direction, or drive the first mounting member 10 to rotate relative to the second mounting member 20 around a center point, etc.

[0055] Through the above embodiments, the optical fiber protection component 40 has an optical fiber inlet 41. The optical fiber protection component 40 is used to guide the optical fiber to connect with the galvanometer component 30, so as to fix the optical fiber through the optical fiber protection component 40 and simplify the assembly difficulty of the welding device 1. The galvanometer component 30 is used to project the welding laser, so that the welding device 1 can perform welding operations by emitting the laser through the optical fiber and the galvanometer component 30. The galvanometer component 30 and the optical fiber protection component 40 are connected to the first mounting member 10. The rotating member 50 is connected to the first mounting member 10 and the second mounting member 20. The rotating member 50 is configured such that the first mounting member 10 drives the galvanometer component 30 and the optical fiber protection component 40 to rotate relative to the second mounting member 20, so that the first mounting member 10 and the second mounting member 20 can be rotated relative to each other by the rotating member 50, changing the position of the optical fiber inlet 41, thereby driving the optical fiber protection component 40 and the galvanometer component 30 to rotate to a specific position that is conducive to the insertion and removal of the optical fiber, reducing the maintenance difficulty and contamination risk of the welding device 1, and also shortening the maintenance time of the welding device 1 and improving the welding efficiency.

[0056] In some embodiments, the rotating member 50 is configured to rotate the first mounting member 10 relative to the second mounting member 20 to switch the welding device 1 between an operating state and a maintenance state; the fiber optic protection component 40 is connected to the optical fiber through the optical fiber inlet 41, the welding device 1 is in the maintenance state, and the opening of the optical fiber inlet 41 is oriented non-upstream along the gravity direction Z.

[0057] The operating status can be understood as: the position of the galvanometer assembly 30 and the fiber optic protection assembly 40 during the welding operation of welding device 1, such as... Figure 1As shown, this illustrates the positions of the galvanometer assembly 30 and the fiber optic protection assembly 40 in the operating state of the welding apparatus 1. In the operating state, the opening of the fiber optic outlet faces upstream in the gravitational direction Z, i.e., the opening of the fiber optic outlet faces upwards. The galvanometer assembly 30 is located downstream of the fiber optic protection assembly 40 along the gravitational direction Z, so that the laser emitted from the fiber optic cable can be projected to a predetermined position through the galvanometer assembly 30. In some embodiments, the welding apparatus 1 is positioned as follows... Figure 1 In the state shown, the optical fiber guiding channel inside the optical fiber protection component 40 can pass through both sides of the optical fiber protection component 40 along the gravity direction Z, that is, the optical fiber inlet 41 and the optical fiber outlet are located at both ends of the optical fiber guiding channel along the gravity direction Z.

[0058] The maintenance status can be understood as: the position of the galvanometer assembly 30 and the fiber optic protection assembly 40 during the maintenance operation of welding device 1, such as... Figure 2 As shown, this illustrates the positions of the galvanometer assembly 30 and the fiber optic protection assembly 40 in the maintenance state of the welding apparatus 1. In the maintenance state, the opening of the fiber optic inlet 41 faces non-upstream along the gravity direction Z, i.e., the opening of the fiber optic outlet faces downwards or as shown... Figure 2 The horizontal orientation is shown. In the maintenance state, the opening of the fiber optic inlet 41 is oriented non-upstream along the gravity direction Z. During operations such as inserting or removing the fiber, external impurities are unlikely to enter the fiber protection assembly 40 vertically from the fiber optic inlet 41, reducing the risk of contaminating the galvanometer during fiber insertion and removal.

[0059] In some embodiments, the welding apparatus 1 includes a fixing member 70, which is detachably connected to the first mounting member 10 and the second mounting member 20 when the welding apparatus 1 is in operation.

[0060] like Figure 1 As shown, the fixing member 70 can be a bolt or similar structure. The first mounting member 10 and the second mounting member 20 can be provided with corresponding fixing holes. In the working state, the fixing holes on the first mounting member 10 and the second mounting member 20 can be correspondingly set, and the fixing member 70 can be simultaneously inserted into the fixing holes of the first mounting member 10 and the second mounting member 20 to maintain the relative fixation of the first mounting member 10 and the second mounting member 20, thereby improving the reliability of the welding device 1 during operation. When it is necessary to adjust the welding device 1 from the working state to the maintenance state, the fixing member 70 can be disassembled to release the fixing state of the first mounting member 10 and the second mounting member 20, so that the welding device 1 can switch from the working state to the maintenance state.

[0061] In some embodiments, the welding device 1 includes a stop member 80, and the first mounting member 10 is provided with a fourth through hole 16. The stop member 80 is connected to the first mounting member 10 through the fourth through hole 16. The stop member 80 is used to abut against the second mounting member 20, and the position of the stop member 80 is adjustable along the direction toward the second mounting member 20.

[0062] The abutment 80 can be a bolt, and the fourth through hole 16 can be a screw hole. The abutment 80 can be disposed within the fourth through hole 16. The abutment 80 can be used to abut against the second mounting member 20, thereby increasing the gap between the first mounting member 10 and the second mounting member 20, so as to facilitate the adjustment of the welding device 1 from the working state to the maintenance state. In some application scenarios, when the welding device 1 is in the working state, the fixing member 70 can be removed first to release the fixing state of the first mounting member 10 and the second mounting member 20. Then, from the side of the first mounting member 10 away from the second mounting member 20, the abutment 80 is inserted into the fourth through hole 16 to abut against the second mounting member 20. The abutment 80 gradually moves towards the direction of the second mounting member 20 to increase the gap between the first mounting member 10 and the second mounting member 20. The first mounting member 10 is then rotated relative to the second mounting member 20 to the maintenance state via the rotating member 50.

[0063] The number of abutment members 80 and the number of fourth through holes 16 can both be multiple, with multiple fourth through holes 16 spaced apart. One abutment member 80 can be inserted into one fourth through hole 16 to stabilize the gap between the first mounting member 10 and the second mounting member 20. The shape of the abutment member 80 can be set according to the actual situation. For example, the abutment member 80 can be columnar, and the periphery of the abutment member 80 can be provided with external threads corresponding to the internal threads of the fourth through holes 16. The end of the abutment member 80 facing the second mounting member 20 can be hemispherical to reduce the contact area between the abutment member 80 and the second mounting member 20 and reduce the obstruction of the abutment member 80 to the rotation of the first mounting member 10 relative to the second mounting member 20.

[0064] See Figures 1 to 3 , Figure 3 yes Figure 1 A schematic diagram of the disassembled structure of the welding device 1 shown.

[0065] The welding device 1 includes a locking member 90. The first mounting member 10 is provided with a first locking hole 17, and the second mounting member 20 is provided with a second locking hole 23. When the welding device 1 is under maintenance, the first locking hole 17 and the second locking hole 23 correspond to each other, and the locking member 90 is simultaneously provided in the first locking hole 17 and the second locking hole 23.

[0066] The first locking hole 17 can be a through hole, and the second locking hole 23 can be a through hole or a blind hole, such as... Figure 2As shown, when the welding device 1 is in the maintenance state, the first locking hole 17 and the second locking hole 23 correspond to each other. The locking member 90 is simultaneously inserted into the first locking hole 17 and the second locking hole 23. By cooperating with the first locking hole 17 and the second locking hole 23, the welding device 1 is kept in the maintenance state, reducing the difficulty of maintenance. The shape of the locking member 90 can be set according to the actual situation. For example, the locking member 90 can be T-shaped. Part of the locking member 90 is inserted into the first locking hole 17 and the second locking hole 23, while the remaining part of the locking member 90 abuts against the surface of the first mounting member 10 away from the second mounting member 20, so as to facilitate the insertion and removal of the locking member 90.

[0067] See further Figure 4 and Figure 5 , Figure 4 yes Figure 1 A schematic diagram of the cross-sectional structure of the welding device 1 along the AA direction. Figure 5 yes Figure 4 The structural diagram within the dashed box.

[0068] The first mounting member 10 has a first surface 11 and a second surface 12 facing away from each other, and the galvanometer assembly 30 and the fiber optic protection assembly 40 are connected to the first surface 11; the second mounting member 20 has a third surface 21 facing the second surface 12; the rotating member 50 is configured such that the first mounting member 10 rotates relative to the second mounting member 20 about a first direction X, wherein the first direction X is perpendicular to the third surface 21.

[0069] The first surface 11 and the second surface 12 can be the main surfaces of the first mounting member 10, that is, the first surface 11 and the second surface 12 can be two opposite surfaces of the first mounting member 10 with larger areas. The third surface 21 can be the side of the second mounting member 20 facing the first mounting member 10, and the second surface 12 and the third surface 21 are arranged opposite each other. The galvanometer assembly 30 and the fiber optic protection assembly 40 are both connected to the first surface 11, reducing interference between the galvanometer assembly 30 and the fiber optic protection assembly 40, and facilitating welding operations by the welding device 1. The rotating member 50 can extend along the first direction X, and the rotating member 50 can rotate around the first direction X, thereby driving the first mounting member 10 to rotate relative to the second mounting member 20 around the first direction X, which allows the first mounting member 10 to rotate in a smaller space and improves the reliability of the rotation of the first mounting member 10.

[0070] The first surface 11 can be a flat surface or an arc surface, or it can be multiple surfaces of the first mounting member 10 located on different planes on the side facing away from the second mounting member 20. The second surface 12 can be a flat surface or an arc surface, or it can be multiple surfaces of the first mounting member 10 located on different planes on the side facing the second mounting member 20. The third surface 21 can be a flat surface or an arc surface, or it can be multiple surfaces of the second mounting member 20 located on different planes on the side facing the first mounting member 10.

[0071] Furthermore, the rotating member 50 is fixedly connected to the first mounting member 10, and the rotating member 50 is movably connected to the second mounting member 20. The rotating member 50 is used to drive the first mounting member 10 to rotate relative to the second mounting member 20 around the first direction X.

[0072] The rotating component 50 is fixedly connected to the first mounting component 10 and movably connected to the second mounting component 20, so as to connect the first mounting component 10 and the second mounting component 20 through the rotating component 50, and to drive the first mounting component 10 to rotate relative to the second mounting component 20 around the first direction X through the rotating component 50, so that the first mounting component 10 can rotate in a smaller space, further improving the reliability of the rotation of the first mounting component 10.

[0073] See further Figures 3 to 5 The rotating member 50 includes a first shaft portion 51 and a second shaft portion 52, which are connected. The first shaft portion 51 extends along a first direction X and along a second direction Y perpendicular to the first direction X. The size of the first shaft portion 51 is smaller than that of the second shaft portion 52. The second mounting member 20 is provided with a first through hole 22, which includes a first hole segment 221 and a second hole segment 222. The first hole segment 221 connects the second hole segment 222 and the third surface 21 along the second direction Y. The diameter of the first hole segment 221 is smaller than that of the second hole segment 222. The first shaft portion 51 passes through the first hole segment 221 and is connected to the first mounting member 10. The second shaft portion 52 is disposed in the second hole segment 222.

[0074] The first shaft portion 51 can be cylindrical, and its axial direction can be perpendicular to the third surface. The second shaft portion 52 can be disc-shaped, and its axial direction can coincide with that of the first shaft portion 51. The second shaft portion 52 is connected to one end of the first shaft portion 51 and extends along a second direction Y perpendicular to the first direction X. The size of the first shaft portion 51 is smaller than that of the second shaft portion 52, so that the first shaft portion 51 and the second shaft portion 52 together form a T-shaped structure.

[0075] The first hole segment 221 can be cylindrical, and its axial direction can be perpendicular to the third surface. The second hole segment 222 can be cylindrical, and its axial direction can coincide with that of the first hole segment 221. The second hole segment 222 is connected to the first hole segment 221 along a second direction Y perpendicular to the first direction X. The size of the first hole segment 221 is smaller than that of the second hole segment 222, and a step can be formed at the connection between the first hole segment 221 and the second hole segment 222.

[0076] The first shaft portion 51 passes through the first hole section 221 and is fixedly connected to the first mounting member 10. The second shaft portion 52 is disposed in the second hole section 222. The step at the connection between the first hole section 221 and the second hole section 222 limits the second shaft portion 52 in the first direction X. The second shaft portion 52 is also limited in the second direction Y by the hole wall of the second hole section 222. The second shaft portion 52 and the first shaft portion 51 can rotate in the circumferential direction of the second hole section 222, that is, the second shaft portion 52 and the first shaft portion 51 can rotate around the first direction X, thereby realizing the movable connection between the rotating member 50 and the second mounting member 20.

[0077] Furthermore, the first mounting member 10 is provided with a second through hole 13, which penetrates the first surface 11 and the second surface 12. The second through hole 13 and the first through hole 22 correspond to each other in the first direction X. The second shaft portion 52 passes through the second through hole 13. The rotating member 50 includes a third shaft portion 53, which is located on the side of the first mounting member 10 away from the second mounting member 20. The third shaft portion 53 is connected to the second shaft portion 52 and the first mounting member 10.

[0078] The second through hole 13 can be cylindrical, penetrating through the first surface 11 and the second surface 12. The first through hole 22 and the second through hole 13 can be coaxially arranged. The third shaft portion 53 is located on the side of the first mounting member 10 away from the second mounting member 20, reducing interference between the third shaft portion 53 and the second mounting member 20. The third shaft portion 53 is fixedly connected to the first mounting member 10. The second shaft portion 52 can protrude from the first surface 11, and the second shaft portion 52 is fixedly connected to the first shaft portion 51. The rotating member 50 can be fixedly connected to the first mounting member 10 through the third shaft portion 53, simplifying the installation difficulty of the rotating member 50.

[0079] In some embodiments, along the second direction Y, the size of the second shaft portion 52 is smaller than the diameter of the second hole segment 222.

[0080] Along the second direction Y, the size of the second shaft portion 52 is smaller than the diameter of the second hole segment 222, allowing the second shaft portion 52 and the second hole segment 222 to have a clearance fit. For example, the difference between the diameter of the second shaft portion 52 in the second direction Y and the diameter of the second hole segment 222 can be greater than or equal to 0.4 and less than or equal to 0.6. Exemplarily, the difference between the diameter of the second shaft portion 52 in the second direction Y and the diameter of the second hole segment 222 can be 0.4, 0.45, 0.5, 0.55, or 0.6. This can reduce the interference of the second mounting member 20 with the rotation of the first mounting member 10, thereby improving the rotation efficiency of the first mounting member 10. The second shaft portion 52 and the second through hole 13 can have a clearance fit, an interference fit, or a transition fit. For example, an interference fit or a transition fit between the second shaft portion 52 and the second through hole 13 is more conducive to the rotation of the first mounting member 10 relative to the second mounting member 20 with the rotating member 50.

[0081] In some embodiments, the first mounting member 10 includes a main mounting portion 14 and an assembly portion 15. A second through hole 13 is disposed in the assembly portion 15. The main mounting portion 14 is provided with a third through hole 141 extending along a first direction X. The assembly portion 15 includes a first portion 151 and a second portion 152. Along a second direction Y, the size of the first portion 151 is smaller than the size of the second portion 152. The first portion 151 is disposed in the third through hole 141. The second portion 152 is located on the side of the main mounting portion 14 away from the second mounting member 20. The second portion 152 is connected to the first portion 151. A third shaft portion 53 is located on the side of the second portion 152 away from the first portion 151.

[0082] The main mounting portion 14 can be plate-shaped. A third through hole 141 penetrates both opposite surfaces of the main mounting portion 14 along the first direction X. The third through hole 141 can be coaxially arranged with the first through hole 22. A second through hole 13 is provided in the assembly portion 15. The second through hole 13 can penetrate both opposite surfaces of the assembly portion 15 along the first direction X. When the assembly portion 15 is provided in the main mounting portion 14, the second through hole 13 can be coaxially arranged with the third through hole 141. The shape of the first portion 151 can match the shape of the third through hole 141. For example, both the first portion 151 and the third through hole 141 can be cylindrical, or both can be polygonal prisms, etc. The shape of the second portion 152 can be set according to the actual situation. For example, the shape of the third portion can be cylindrical, polygonal prism, etc. Along the second direction Y, the size of the first portion 151 is smaller than the size of the second portion 152, so that the first portion 151 and the second portion 152 can together form a T-shaped structure. The first part 151 is disposed in the third through hole 141, the second part 152 is located on the side of the main mounting part 14 away from the second mounting member 20, the second part 152 is connected to the first part 151, the first part 151 and the second part 152 can be integrally formed, the second part 152 can be detachably connected to the main mounting part 14, the third shaft part 53 is located on the side of the second part 152 away from the first part 151, the third shaft part 53 can be detachably connected to the main mounting part 14, the assembly tolerance between the rotating member 50 and the first mounting member 10 can be reduced by the assembly part 15 cooperating with the main mounting part 14, and the assembly accuracy of the welding device 1 can be improved.

[0083] See further Figure 4 and Figure 5 Along the first direction X, the length of the second shaft portion 52 is greater than the sum of the length of the first hole segment 221 and the length of the through hole.

[0084] Along the first direction X, the length of the second shaft portion 52 is greater than the sum of the length of the first hole segment 221 and the length of the through hole, which allows the first mounting member 10 to form a gap with the second mounting member 20 when it needs to rotate relative to the second mounting member 20, thereby reducing the interference of the second mounting member 20 with the rotation of the first mounting member 10 and improving the rotation efficiency of the first mounting member 10.

[0085] When the welding device 1 is in operation, the first mounting member 10 and the second mounting member 20 can be detachably connected via the fixing member 70. The second surface 12 of the first mounting member 10 can fit against the third surface 21 of the second mounting member 20. Since the length of the second shaft portion 52 is greater than the sum of the length of the first hole segment 221 and the length of the through hole, a gap can be formed between the third shaft portion 53 and the first mounting member 10, and / or a gap can be formed between the second shaft portion 52 and the second mounting member 20. Figure 5As shown, when the welding device 1 is in operation, the second surface 12 of the first mounting member 10 can fit against the third surface 21 of the second mounting member 20, and there is a gap between the third shaft portion 53 and the first mounting member 10.

[0086] When it is necessary to switch the welding device 1 from the working state to the maintenance state, the fixing state of the first mounting member 10 and the second mounting member 20 can be released first. Since the length of the second shaft 52 is greater than the sum of the length of the first hole section 221 and the length of the through hole, the second mounting member 20 can be abutted by the abutment member 80, so that the first mounting member 10 and the second mounting member 20 are separated. At the same time, the second shaft 52 abuts against the second mounting member 20, and the third shaft 53 abuts against the first mounting member 10, so as to fix the third shaft 53 and the first mounting member 10, so as to reduce the interference of the second mounting member 20 with the rotation of the first mounting member 10 and improve the rotation efficiency of the first mounting member 10.

[0087] Furthermore, the difference between the sum of the lengths and the length of the second shaft portion 52 is greater than or equal to 1 mm and less than or equal to 2 mm.

[0088] The difference between the length of the first hole segment 221 and the length of the through hole, and the length of the second shaft portion 52, can be 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, etc. Specifically, the difference between the length of the first hole segment 221 and the length of the through hole, and the length of the second shaft portion 52, can be greater than or equal to 1 mm and less than or equal to 1.5 mm, greater than or equal to 1.5 mm and less than or equal to 2 mm, greater than or equal to 1.2 mm and less than or equal to 1.8 mm, greater than or equal to 1.4 mm and less than or equal to 1.6 mm, greater than or equal to 1.3 mm and less than or equal to 1.9 mm, greater than or equal to 1 mm and less than or equal to 1.4 mm, etc. By setting an appropriate length difference, the risk of the second mounting member 20 interfering with the first mounting member 10 can be reduced, and the compactness of the welding device 1 can also be improved.

[0089] See Figure 6 , Figure 6 This is a second structural schematic diagram of the welding apparatus 1 in operation according to one or more embodiments of this application.

[0090] The welding device 1 includes an auxiliary rotating rod 60, which is connected to the first mounting component 10.

[0091] The auxiliary rotating rod 60 can be long and rod-shaped. One end of the auxiliary rotating rod 60 is connected to the first mounting member 10. The auxiliary rotating rod 60 can extend away from the first mounting member 10 and the second mounting member 20, that is, the auxiliary rotating rod 60 extends beyond the first mounting member 10, or in other words, the orthogonal projection of the auxiliary rotating rod 60 along the first direction X does not coincide with the first mounting member 10 at least partially. The first mounting member 10 can be rotated by the auxiliary rotating rod 60, reducing the external force required to rotate the first mounting member 10 and lowering the difficulty of rotating the first mounting member 10. For example, an external force can be applied to the auxiliary rotating rod 60 to switch the welding device 1 between the working state and the maintenance state. The length of the auxiliary rotating rod 60 can be set according to the actual situation. For example, the length of the auxiliary rotating rod 60 can be between 700mm and 900mm. The specific length of the auxiliary rotating rod 60 can be 700mm, 800mm or 900mm, etc. The weight of the galvanometer assembly 30 can be 35KG. The external force applied to the auxiliary rotating rod 60 can be reduced according to the torque balance principle, and the first mounting member 10 can also rotate relative to the second mounting member 20.

[0092] In summary, the fiber optic protection component 40 is used to guide the connection between the fiber optic cable and the galvanometer assembly 30, so as to fix the fiber optic cable through the fiber optic protection component 40 and simplify the assembly difficulty of the welding device 1. The galvanometer assembly 30 is used to project the welding laser, so that the welding device 1 can perform welding operations by emitting the laser through the fiber optic cable and the galvanometer assembly 30. The galvanometer assembly 30 and the fiber optic protection component 40 are connected to the first mounting component 10. The rotating component 50 is connected to the first mounting component 10 and the second mounting component 20. The rotating component 50 is configured such that the first mounting component 10 drives the galvanometer assembly 30 and the fiber optic protection component 40 to rotate relative to the second mounting component 20. This allows the first mounting component 10 and the second mounting component 20 to rotate relative to each other through the rotating component 50, thereby driving the fiber optic protection component 40 and the galvanometer assembly 30 to rotate to a specific position that facilitates the insertion and removal of the fiber optic cable. This reduces the maintenance difficulty and contamination risk of the welding device 1, and also shortens the maintenance time of the welding device 1 and improves the welding efficiency.

[0093] To address the technical problems existing in the related technologies, this application also provides a battery production equipment, which includes a welding device 1 as described in any of the above embodiments.

[0094] The welding device 1 can be used in any process during battery production that requires welding. For example, a battery cell is a basic component of a battery module, and a connector bar (or electrode plate) acts as a connector between battery cells, linking multiple battery cells together to form a battery module. The electrode plate rationally distributes the current and voltage between the battery cells, thereby ensuring the normal operation of the entire battery module. The welding device 1 can weld the terminals of the battery cells in the battery module to the electrode plate.

[0095] Battery production equipment may include a transmission device, a laser, and optical fibers. The second mounting component 20 of the welding device 1 can be connected to the transmission device, which can drive the first mounting component 10, the second mounting component 20, the galvanometer assembly 30, and the optical fiber protection assembly 40 to a specific position to perform the welding operation. The optical fiber can be inserted into the optical fiber protection assembly 40 and connected to the galvanometer assembly 30 of the welding device 1. The other end of the optical fiber can be connected to the laser, and the high-power laser generated by the laser can be transmitted to the galvanometer assembly 30 through the optical fiber.
