Therefore, the present application provides a battery negative electrode bottom welding device to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a battery negative electrode bottom welding device to solve the problem that the battery position needs to be readjusted after the existing welding device welds a single battery.

[0005] In order to solve the above technical problems, the present utility model provides the following technical solutions.

[0010] It also includes: a pressing plate, which is arranged in the placing frame; a cylinder, which is arranged on the top of the placing frame, and the output end of the cylinder passes through the placing frame and is connected to the pressing plate.

[0011] It also includes: multiple baffles, which are slidably set in the placement frame, and the baffles include: a first connecting plate, which is slidably set at the bottom of the inner cavity of the placement frame, and the outermost first connecting plate is connected to the second electric slide rail; the top of the first connecting plate is convex; the second connecting plate is slidably set at the top of the inner cavity of the placement frame; a placement groove is set in the second connecting plate, and matches the convex shape of the first connecting plate.

[0012] It also includes: a plurality of springs, one end of which is connected to the top of the first connecting plate and the other end is connected to the placement groove; a plurality of limiting cylinders, which are sleeved on the surface of the springs and connected to the first connecting plate.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects.

DETAILED DESCRIPTION

[0027] The following describes in detail a battery negative electrode bottom welding device provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for known techniques. Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0028] like Figure 1 - Figure 8 As shown, an embodiment of the present invention provides a battery negative electrode bottom welding device, comprising: a workbench 1; a turntable 4, rotatably arranged on the top of the workbench 1; a rotating component 6, arranged on the workbench 1, for driving the turntable 4 to rotate; a plurality of fixed components 5, arranged on the turntable 4, distributed in a circular pattern; a plurality of battery bodies 7, arranged in the fixed components 5; a welding component 2, arranged on the workbench 1, for welding the battery body 7; an infrared sensor 3, arranged on the welding component 2, for positioning the battery body 7.

[0029] By setting up the infrared sensor 3, high-precision positioning of the battery body 7 can be achieved. When the turntable 4 drives the multiple fixed components 5 with fixed batteries to rotate, the infrared sensor 3 can accurately detect when each battery reaches the welding position. This precise positioning effect can control the positioning error within an extremely small range.

[0030] The welding assembly 2 includes a first electric slide 22 mounted on the workbench 1 and a laser generator 21 mounted on the first electric slide 22. The first electric slide 22 provides a movable platform for the laser generator 21. Once the infrared sensor 3 detects that the battery body 7 has reached the welding position, the first electric slide 22 can precisely move the laser generator 21 to the optimal welding starting point according to a preset program or the specific location information of the battery.

[0031] Rotating assembly 6 includes a mounting frame 61 positioned at the center of the bottom of workbench 1; and a motor 62 disposed within mounting frame 61. The output end of motor 62 extends through workbench 1 and connects to turntable 4. By securing motor 62 to turntable 4, the output end generates rotational force when an external current is applied to motor 62, driving turntable 4 to synchronize its motion and providing the power source for its rotation.

[0032] The fixing assembly 5 includes a placement frame 51, which is mounted on the workbench 1; and a second motorized slide 55, which is mounted at the bottom of the placement frame 51. The second motorized slide 55 drives the outermost baffle 54 to move, thereby moving the multiple battery bodies 7 and the baffle 54, securing the sides of the battery bodies 7 and limiting horizontal movement of the batteries.

[0033] The device also includes a pressure plate 52, which is disposed within the placement frame 51; and a cylinder 53, which is disposed at the top of the placement frame 51, with the output end of the cylinder 53 extending through the placement frame 51 and connected to the pressure plate 52. The pressure plate 52 cooperates with the cylinder 53 during the battery securing process to effectively secure the battery in the vertical direction, firmly confining the battery to its lower position. A sponge or gasket can be placed on the pressure plate 52 to cushion and evenly distribute pressure, ensuring a more even pressure on the top of the battery and preventing the pressure plate 52 from scratching or wearing the top surface of the battery during the securing process.

[0034] It also includes: multiple baffles 54, which are slidably set in the placement frame 51, and the baffles 54 include: a first connecting plate 541, which is slidably set at the bottom of the inner cavity of the placement frame 51, and the outermost first connecting plate 541 is connected to the second electric slide rail 55; the top of the first connecting plate 541 is convex; the second connecting plate 543, which is slidably set at the top of the inner cavity of the placement frame 51; a placement groove is set in the second connecting plate 543, and matches the convex shape of the first connecting plate 541.

[0035] By setting up the second connecting plate 543, when the cylinder 53 drives the pressure plate 52 to move downward, the second connecting plate 543 moves synchronously, avoiding the interference between the limiting pressure plate 52 and the second connecting plate 543 during the descending process. At the same time, the placement groove in the second connecting plate 543 is inserted into the convex shape of the first connecting plate 541, thereby adjusting the height of the baffle 54.

[0036] It also includes: multiple springs 544, one end of which is connected to the top of the first connecting plate 541 and the other end is connected to the placement groove; multiple limiting cylinders 542, which are sleeved on the surface of the springs 544 and connected to the first connecting plate 541.

[0037] By setting the spring 544, when the second connecting plate 543 moves downward, the spring 544 is compressed, thereby providing elastic force for the subsequent reset of the second connecting plate 543. At the same time, the compression degree of the spring 544 is limited by the limiting cylinder 542 to avoid excessive deformation of the spring 544, which makes it impossible to reset.

[0038] The technical solution provided by the present invention is to adjust the gap between the baffle 54 and the placement frame 51, and place multiple battery bodies 7 therein respectively. The second electric slide 55 and the cylinder 53 are operated simultaneously, and the cylinder 53 is extended to drive the pressure plate 52 to move downward, so that the second connecting plate 543 moves downward, and the spring 544 is compressed to fix the top of the battery body 7. The second electric slide 55 drives one of the baffles 54 to move, thereby fixing the side of the battery body 7; the motor 62 is turned on by the peripheral controller to drive the turntable 4 to rotate, and the battery body 7 is rotated to the laser generator 21. The laser generator 21 is driven to move by the first electric slide 22 and the infrared sensor 3, so that the battery body 7 is welded. After the welding is completed, the turntable 4 rotates to move the new battery body 7 to the laser generator 21 for welding.

[0039] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
