[0002] In today's industrial manufacturing field, the requirements for metal connection technology are increasing day by day. Due to its unique physical and chemical properties, metal foil has been widely used in many fields such as electronics, aerospace, new energy, etc. However, traditional welding methods often face many challenges when dealing with metal foil. With the continuous progress of technology, laser technology has gradually become an ideal choice for metal foil welding due to its significant advantages such as high precision, high energy density, and small heat affected zone. Laser welding can achieve a firm connection while minimizing the impact on the material properties of the metal foil, ensuring the quality and reliability of the welded part.

[0003] Currently, the disadvantages of metal foil laser welding devices on the market are as follows: When a general laser welding device welds metal foil, it is necessary for workers to manually hold two metal foils against the operating table for fixation and then perform welding. Holding the metal foil for a long time easily causes soreness in the worker's hands and is likely to cause the metal foil to shift, thus affecting the welding stability of the metal foil. For this reason, we have designed a metal foil laser welding device. Summary of the Utility Model

[0004] The technical problem solved by the utility model is to provide a metal foil laser welding device with high practicability, which can be operated simply and has a relatively simple structure, and solves the problems of soreness in the worker's hands easily caused by holding the metal foil for a long time and the metal foil being likely to shift, thus affecting the welding stability of the metal foil as mentioned in the above background art.

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A metal foil laser welding device includes a base and a movable clamping mechanism assembled inside the base;

[0006] The base includes a U-shaped frame and brackets fixedly connected to both sides of the U-shaped frame. A rectangular groove is provided in the bracket. A first hydraulic rod is fixedly connected to one side of the bracket. The output end of the first hydraulic rod is fixedly connected to a slider.

The output end of the second hydraulic rod is fixedly installed with a laser welding device body. Sliding grooves are provided on both sides of the inner wall of the U-shaped frame;

[0007] The movable clamping mechanism includes two placing plates slidably connected inside the chute, a third hydraulic rod fixedly connected to the center of the inner bottom wall of the U-shaped frame, and a bidirectional threaded rod mounted inside the U-shaped frame. The output end of the third hydraulic rod is fixedly connected to a fixing plate. Two movable plates are slidably connected to the top of the fixing plate. The two movable plates are threadedly connected to the bidirectional threaded rod. Four through slots are formed on the surfaces of the two placing plates. Four rectangular plates are slidably connected inside the four through slots. The bottoms of the four rectangular plates are fixedly connected to the two sides of the top of the movable plates. Two rectangular blocks are fixedly connected to the tops of the four rectangular plates. Six springs are fixedly connected to the bottoms of the two rectangular blocks. Buffer rods are sleeved inside the six springs. Two pressing plates are fixedly connected to the bottoms of the six springs. Four telescopic rods are fixedly connected to the tops of the two movable plates. One ends of the four telescopic rods are fixedly connected to the bottoms of the placing plates.

[0008] Optionally, a T-shaped slot is formed on one side of the two placing plates, and a rectangular placing groove is formed on the tops of the two placing plates.

[0013] The metal foil laser welding device, through the settings of the base and the movable welding device, places two metal foils to be welded on the placement plate, making one side of the metal foil extend a small part outside the placement plate in parallel, so that the parts of the two metal foils to be welded are in a suspended state. Then, the hydraulic rod is opened to drive the fixed plate and the movable plate to descend, thereby driving the rectangular plate to descend, driving the rectangular block and the spring at its bottom to descend, pressing the pressure plate against the metal foil, and the spring can preferably press the metal foils of different thicknesses against the placement plate. Then, the bidirectional threaded rod is rotated to make the two movable plates approach each other.

The movable clamping mechanism 2 includes two placing plates 201 slidably connected inside the sliding grooves 108, a third hydraulic rod 202 fixedly connected to the center of the inner bottom wall of the U-shaped frame 101, and a bidirectional threaded rod 203 erected inside the U-shaped frame 101. The output end of the third hydraulic rod 202 is fixedly connected to a fixing plate 204. Two movable plates 205 are slidably connected to the top of the fixing plate 204. The bidirectional threaded rod 203 is threadedly connected to the surfaces of the two movable plates 205. Four through grooves 206 are provided on the surfaces of the two placing plates 201. Four rectangular plates 207 are slidably connected inside the four through grooves 206. The bottoms of the four rectangular plates 207 are fixedly connected to both sides of the top of the movable plate 205. Two rectangular blocks 208 are fixedly connected to the tops of the four rectangular plates 207. Six springs 209 are fixedly connected to the bottoms of the two rectangular blocks 208. A buffer rod is sleeved inside the six springs 209. Two pressing plates 210 are fixedly connected to the bottoms of the six springs 209. Four telescopic rods 211 are fixedly connected to the tops of the two movable plates 205. One ends of the four telescopic rods 211 are fixedly connected to the bottom of the placing plate 201. Place the two metal foils to be welded on the placing plate 201, so that one side of the metal foil extends a small part outside the placing plate 201 in parallel, and the places where the two metal foils are to be welded are in a suspended state. Then turn on the hydraulic rod to drive the fixing plate 204 and the movable plate 205 to descend, thereby driving the rectangular plate 207 to descend, driving the rectangular block 208 and the springs 209 at its bottom to descend, so that the pressing plate 210 presses the metal foil on the base 1, and the springs 209 can preferably press the metal foils of different thicknesses against the placing plate 201. Then rotate the bidirectional threaded rod 203 to make the two movable plates 205 approach each other. At the same time, drive the placing plate 201 and the movable plate 205 to move synchronously through the telescopic rods 211, so that the places where the two clamped metal foils extend out of the placing plate 201 approach each other. Then start the laser welding device body 107, turn on the first hydraulic rod 104 and the second hydraulic rod 106 to push the laser welding device body 107 to weld along the place where the two metal foils are close to each other, which plays the role of not requiring manual resistance to the metal foil during welding, reduces the labor force of the staff during welding, and improves the welding stability of the device for metal foils at the same time.

[0021] Further, a T-shaped groove is formed on one side of each of the two placement plates 201, and a rectangular placement groove is formed on the top of the two placement plates 201.

After alignment, with the start of the third hydraulic rod 202, the guide rods 4 are driven to move through the connecting blocks 3, and then the other end of the guide rod 4 drives the pressing block 5 to slide in the T-shaped groove of the placement plate 201, so that the pressing block 5 no longer blocks the metal foil.

[0023] Further, movable grooves for the pressing block 5 to move are formed on both sides of the U-shaped frame 101, and a rubber pad 6 is fixedly connected to the bottom of the U-shaped frame 101. Among them, the rubber pad 6 can reduce the slipping of the device when placed.

[0026] After placing the metal foil on the placement plate 201, push one side of the metal foil until it abuts against one side of the abutting block 5, then the alignment of the metal foil can be quickly completed, so that the parts of the two metal foils to be welded are on the abutting block 5. Then, turn on the hydraulic rod to drive the fixed plate 204 and the movable plate 205 to descend, thereby driving the rectangular plate 207 to descend, driving the rectangular block 208 and the spring 209 at its bottom to descend, so that the pressing plate 210 presses the metal foil on the base 1, and the spring 209 can preferably press metal foils of different thicknesses against the placement plate 201. With the start of the third hydraulic rod 202, the connecting block 3 is driven to move downward through the movable plate 205, and at the same time the guide rod 4 is driven to move. Then, the other end of the guide rod 4 drives the abutting block 5 to slide in the T-shaped groove of the placement plate 201, so that the abutting block 5 no longer blocks the metal foil. Then, rotate the bidirectional threaded rod 203 to make the two movable plates 205 approach each other, and at the same time drive the placement plate 201 and the movable plate 205 to move synchronously through the telescopic rod 211, so that the parts of the two clamped metal foils extending out of the placement plate 201 approach each other.
