Description

Technical Field

[0001] This utility model belongs to the technical field of welding equipment, and more specifically, it relates to a narrow-edge magnetic vacuum fixing welding device for bimetallic laser welding. Background Technology

[0002] In the bimetallic laser welding process, the upper thin metal layer usually needs to be fixed by a pressure plate to prevent thermal deformation or poor welding. When the edge width of the nickel sheet is too narrow, the traditional pressure plate will not be able to achieve effective pressing due to size limitations. It is necessary to replace the pressure plate with a micro clamp to fix the nickel sheet and copper busbar.

[0003] For example, CN213163629U discloses a metal bipolar plate laser welding device, including a welding machine platform, a machine cover, a motion mechanism, a load platform, and a clamping structure. The machine cover is sealed and fastened to the welding machine platform, and a vacuum port is opened on the machine cover. The load platform is installed on the welding machine platform via the motion mechanism. The clamping structure includes a permanent magnet chuck, a tooling base, and a tooling pressure plate. The permanent magnet chuck is installed on the load platform, the tooling base is fixed on the permanent magnet chuck, the metal bipolar plate is positioned on the tooling base, and the tooling pressure plate is positioned on the metal bipolar plate. The tooling base and the tooling pressure plate cooperate with the lower and upper bipolar plates, respectively. The tooling pressure plate is made of magnetic material to apply uniform downward pressure when magnetization is applied, so that the metal bipolar plate is tightly attached to the tooling pressure plate and the tooling base. A welding laser head is installed on the machine cover, and a through hole is opened in the upper part of the machine cover and a light-transmitting plate is installed. This device not only helps to improve the quality of metal bipolar plate laser welding, but also has a simple structure, is easy to operate, and has good performance.

[0004] Based on the above, when welding nickel sheets and copper busbars of different sizes, workers need to frequently change pressure plates and miniature clamps, which not only increases the workload of workers but also causes long downtime of the welding equipment, affecting the welding efficiency of nickel sheets and copper busbars.

It also significantly shortens the downtime of the welding device, ensuring continuous and stable welding operations and effectively improving the welding efficiency of nickel sheets and copper busbars. The relative positions of the nickel sheets and copper busbars are initially limited by a position limiting rod. A negative pressure air pump and extraction pipe ensure the copper busbar is stably adsorbed above the heat-insulating ceramic sheet.

Adjusting the position of the strong positioning magnet facilitates the fixing of nickel sheets and copper busbars of different sizes, effectively improving the applicability of the welding device.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. Example 1

[0021] As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a narrow-edge magnetic vacuum fixed welding device for bimetallic laser welding, including a laser welding machine body 1, a linear module 2, a limiting welding table 3, a limiting structure, heat-insulating ceramic sheets 4, guide connecting grooves 5, and positioning strong magnets 6; the linear module 2 is located on the front side of the laser welding machine body 1, and a slider is slidably connected to the upper part of the linear module 2; the limiting welding table 3 is bolted to the upper side of the upper slider of the linear module 2; the limiting structure is located on the upper part of the limiting welding table 3; multiple heat-insulating ceramic sheets 4 are provided, and the multiple heat-insulating ceramic sheets 4 are evenly distributed and fixedly connected to the upper part of the limiting welding table 3; multiple guide connecting grooves 5 are formed in a circular array on the lower part of each heat-insulating ceramic sheet 4; multiple positioning strong magnets 6 are provided, and the multiple positioning strong magnets 6 are slidably connected to the inner side of the multiple guide connecting grooves 5 respectively.

[0022] The limiting structure includes a drive winding shaft 303 and a reciprocating self-locking drive component 304. Multiple drive winding shafts 303 are provided, and the multiple drive winding shafts 303 are rotatably connected to the middle of multiple heat-insulating ceramic sheets 4. The multiple drive winding shafts 303 are all rotatably connected to the limiting welding table 3. Multiple reciprocating self-locking drive components 304 are provided, and the multiple reciprocating self-locking drive components 304 are bolted to the left and right sides of the limiting welding table 3. The multiple drive winding shafts 303 are coaxially fixedly connected to the output shafts of the multiple reciprocating self-locking drive components 304.

[0023] The limiting structure also includes a position limiting rod 301 and an air extraction pipe 401; multiple position limiting rods 301 are provided, and multiple position limiting rods 301 are evenly distributed and fixedly connected to the upper end face of the limiting welding table 3; multiple air extraction pipes 401 are provided, and multiple air extraction pipes 401 are respectively fixedly connected to the inner side of multiple heat insulation ceramic sheets 4, and multiple air extraction pipes 401 are all connected to a negative pressure air pump.

[0024] The specific usage and function of this embodiment are as follows: When welding nickel sheets and copper busbars using a laser welding machine, the copper busbar is first placed above the limiting welding table 3, and then the nickel sheet is placed on top of the copper busbar. At this time, the position limiting rod 301 will pass through the positioning holes of the nickel sheet and the copper busbar, and the relative position of the nickel sheet and the copper busbar will be initially limited by the position limiting rod 301. The negative pressure air pump will draw away the air below the copper busbar through the air extraction pipe 401, so that the copper busbar is adsorbed above the heat insulation ceramic sheet 4. At the same time, the attraction of the positioning strong magnet 6 on the nickel sheet will make the nickel sheet and the copper busbar fit tightly together, so as to avoid the nickel sheet and the copper busbar shifting during the welding process. During the welding process, the linear module 2 can drive the limiting welding table 3 to change position, so that the nickel sheet and the copper busbar to be welded are moved below the welding head. Example 2

[0025] As attached Figure 2 To be continued Figure 6 As shown: Based on Embodiment 1, an adjustment structure is also included; the adjustment structure is located inside the limiting welding station 3.

[0026] The adjustment structure includes a drive gear 306 and a driven gear 307. Multiple drive gears 306 are provided, and the multiple drive gears 306 are evenly distributed and fixedly connected to the lower part of multiple drive winding shafts 303. Multiple driven gears 307 are provided, and the multiple driven gears 307 are evenly distributed and rotatably connected to the inner side of the limiting welding table 3. The multiple driven gears 307 mesh with the multiple drive gears 306 respectively.

[0027] The adjustment structure also includes guide grooves 302 and guide connecting blocks 601; multiple guide grooves 302 are provided, and multiple guide grooves 302 are evenly distributed in the middle of the limiting welding table 3; multiple guide connecting blocks 601 are provided, and multiple guide connecting blocks 601 are fixedly connected to the lower part of multiple positioning strong magnets 6, and multiple guide connecting blocks 601 are slidably connected to multiple guide grooves 302 respectively.

[0028] The adjustment structure also includes a limiting baffle 305, a reset elastic element 602, and a traction rope 603; two limiting baffles 305 are fixedly connected to the middle of each drive winding shaft 303; multiple reset elastic elements 602 are provided, and multiple guide connecting blocks 601 are elastically connected to the limiting welding table 3 through multiple reset elastic elements 602; multiple traction ropes 603 are provided, and multiple traction ropes 603 are fixedly connected to the middle of multiple guide connecting blocks 601 respectively, and multiple traction ropes 603 are fixedly connected to multiple drive winding shafts 303 respectively.

[0029] The specific usage and function of this embodiment are as follows: When welding small-sized nickel sheets and copper busbars is required, the reciprocating self-locking drive 304 is activated, causing it to rotate the drive winding shaft 303. The rotation of the drive winding shaft 303 drives the driving gear 306 to rotate, which in turn drives the driven gear 307 to rotate. This driven gear 307 then drives the adjacent driving gear 306 and the drive winding shaft 303 to rotate. The rotation of the drive winding shaft 303 then engages the traction rope 603. The winding process causes the traction rope 603 to pull the guide connecting block 601 and the positioning strong magnet 6 to slide inward along the guide slide groove 302 and the guide connecting groove 5, changing the position of the positioning strong magnet 6. The limiting baffle 305 can limit the traction rope 603, so that the traction rope 603 overlaps with each other during winding. When it is necessary to weld larger nickel sheets and copper busbars, the reciprocating self-locking drive 304 reverses, causing the reset elastic element 602 to push the guide connecting block 601 and the positioning strong magnet 6 to slide outward, thereby fixing nickel sheets and copper busbars of different sizes.
