Description

Technical Field

[0001] The invention relates to the field of busbar welding, in particular to a battery busbar welding device with a stirring device. Background Art

[0002] The welding process is a crucial step in the battery production process, and the quality of welding will directly affect the quality of the finished battery.

[0003] Chinese patent publication number CN115007965A discloses a lead-acid battery cast welding device and a drip welding method thereof, comprising a wire conveyor rack for automatically conveying the lead wire. The wire conveyor rack is provided with a conveying mechanism for uniformly conveying the lead wire, a driving mechanism for driving the wire conveyor rack to move in a horizontal direction, and a flame head for moving synchronously with the wire conveyor rack to heat and melt the end of the lead wire to form lead liquid, and then drip the lead liquid into a mold cavity.

[0004] In actual use, after the molten lead flows into the cavity, it takes a certain amount of time to cool down. During the continuous falling process of the molten lead, certain bubbles will often invade the cavity. Although the vertical flame head used can reheat the molten lead to squeeze out certain bubbles, there are still some bubbles in the molten lead, which makes the welding effect worse.

[0005] Therefore, a busbar welding device is needed that can stir the molten lead up and down when the molten lead is injected into the cavity, thereby reducing bubbles in the molten lead and improving welding quality. Summary of the Invention

[0006] In order to solve the problems existing in the prior art, the present invention provides a battery busbar welding device with a stirring device. During welding, as the lead wire is transported, the top moves up and down to reduce bubbles in the lead liquid in the cavity, thereby improving the welding quality.

[0007] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a battery busbar welding device with a stirring device, comprising A battery busbar welding device with a stirring device includes a wire conveyor frame, a drive motor is installed on the wire conveyor frame, and the drive motor is connected to a drive wheel in a transmission manner. When the drive wheel rotates, the wire is conveyed from the wire conveyor frame to an obliquely arranged flame head, where it is heated, melted, and dripped into a mold cavity. A vertically arranged pin is arranged in front of the flame head. The drive wheel is coaxially fixedly connected to a rotating wheel A, which is connected to a crank slider assembly in a transmission manner. The crank slider assembly drives the pin to reciprocate in the vertical direction.

[0008] Further, the crank-slider assembly is fixedly connected to the wire conveying frame. The crank-slider assembly includes a transmission wheel B. One end of a connecting rod A is eccentrically rotatably connected to the transmission wheel B. The other end of the connecting rod A is rotatably connected to one end of a guide rail. The guide rail is slidably connected to a slider. The slider is vertically fixedly connected to the wire conveying frame. The pin is fixedly connected to the free end of the guide rail.

[0009] Further, a cross-shaped groove is provided at the free end of the pin. Further, the depth of the cross-shaped groove is 2 - 3 mm, and the width is 1.5 - 2 mm.

[0010] Further, the fixed end of a cylinder is vertically fixedly connected to the end of the guide rail. The pin is fixedly connected to the end of the guiding rod of the cylinder.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: When the wire is conveyed through the wire conveying frame, a flame jet head arranged obliquely towards the wire conveying surface is used to melt the wire into molten lead and drip it into the cavity. Since the transmission wheel A and the driving wheel are coaxially arranged, the transmission wheel B is rotated through the synchronous belt to drive the transmission wheel B. Then, through the connecting rod A eccentrically fixed to the transmission wheel B, the guide rail slides up and down along the slider, thereby driving the pin to move vertically, and further driving the molten lead to move, making it more uniform. At the same time, a cross-shaped groove is provided at the free end of the pin. The cross-shaped groove is inserted into the molten lead to squeeze the bubbles and reduce the bubble rate in the molten lead. Meanwhile, by arranging a cylinder to connect the pin, the insertion depth of the pin can be adjusted as needed. When stirring is not required, the position of the pin can be raised by contracting the cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] A battery busbar soldering device with a stirring device, including a lead wire conveying rack 10, a driving motor 101 is installed on the lead wire conveying rack 10, the driving motor 101 is drivingly connected to a driving wheel 102, when the driving wheel 102 rotates, the lead wire is conveyed from the lead wire conveying rack 10 to a flame spraying head 103 arranged obliquely for heating and melting and dripping into a cavity. A vertically arranged inserting needle 205 is arranged in front of the flame spraying head 102. The driving wheel 102 is coaxially and fixedly connected with a rotating wheel A 104, and the rotating wheel A 104 is drivingly connected to a crank-slider assembly 20, and the crank-slider assembly 20 drives the inserting needle 205 to reciprocate in the vertical direction.

[0017] Specifically, during use, the lead wire moves along the lead wire conveying rack 10 and is conveyed along the conveying surface on the lead wire conveying rack 10 under the action of the driving wheel 102 driven by the driving motor 101. At the same time, the flame spraying head 103 arranged obliquely towards the conveying surface heats the lead wire. After the lead wire melts, it enters the cavity along the conveying surface. Adjust the position of the inserting needle 205. The inserting needle 205 is made of a heat-resistant metal rod. The crank-slider assembly 20 moves up and down under the action of the rotating wheel A 104 to stir the lead liquid in the cavity to make it more uniform, and at the same time reduce the bubble rate in the lead liquid.

[0018] A further solution is that the crank-slider assembly 20 is fixedly connected to the lead wire conveying rack 10. The crank-slider assembly 20 includes a transmission wheel B 201. One end of a connecting rod A 202 is eccentrically rotatably connected to the transmission wheel B 201. The other end of the connecting rod A 202 is rotatably connected to one end of a guide rail 203. The guide rail 203 is slidably connected to a slider 204. The slider 204 is vertically fixedly connected to the lead wire conveying rack 10. The inserting needle 205 is fixedly connected to the free end of the guide rail 203. Specifically, by installing the inserting needle 205 on the guide rail 203, the inserting needle 205 can stir the lead liquid more stably as the guide rail 203 moves up and down.

[0019] A further solution is that a cross-shaped groove 2051 is provided at the free end of the inserting needle 205. By providing the cross-shaped groove, when the inserting needle 205 is inserted into the lead liquid, the lead liquid can be better divided, enhancing the turbulent flow effect of the lead liquid. The depth of the cross-shaped groove is 2-3 mm, and the width is 1.5-2 mm.

By providing the cylinder 2031, the position of the insertion pin 205 can be adjusted as needed, effectively controlling the position of the insertion pin 205.

[0021] During specific use, the driving motor 101 rotates to drive the driving wheel 102 to rotate and drive the lead wire to be conveyed. The transmission wheel A104 coaxially fixed with the driving wheel 102 uses synchronous belt transmission and at the same time rotates through the transmission wheel B201 in the crank-slider assembly 20. Through the setting of the transmission ratio between the transmission wheel A104 and the transmission wheel B201, the insertion pin 205 is driven to reciprocate vertically at a frequency of 10 - 20 times per minute; the cross grooves 2051 of the insertion pin 205 generate four-way turbulent bubbles in the lead liquid and discharge along the surface of the insertion pin, thereby improving the uniformity of the lead liquid.

[0022] It should be noted that the above-mentioned embodiments can be freely combined according to needs. The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
