Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to a cast welding device and a cast welding method for a pole terminal. Background Art

[0002] The pole terminal is a component that is directly connected to the busbar at one end and connected to an external conductor or to one pole of an adjacent single cell in a battery pack at the other end. The pole terminal serves as a conductive connection in a battery pack and is usually used to connect storage batteries.

[0003] With the increase of labor and material costs, the overall manufacturing cost of batteries is also increasing, but the market demand is: high quality and low price. In order to meet the market demand, higher requirements are required for the pole terminal process. In the pole terminal component, the tinning process is optimized to bare copper casting flux and tinning process, which also saves some costs. However, in the process of mass use, the pore defect rate of the formed pole terminal is relatively high, reaching about 4%. To solve this problem, we optimize the bare copper forming process. After the optimization, the terminal copper parts produced have zero pore defect rate, low cost, qualified torque, and improve the market competitiveness of batteries. The existing terminal copper parts and bare copper parts process are: bare copper parts + casting flux + tinning liquid + casting molding, and the casting flux composition is zinc chloride + phosphorous acid + pure water. Under the high temperature of lead liquid, it reacts quickly and produces a large amount of white gas. A large amount of gas is difficult to be discharged from the mold in a short time. The gas that is not discharged is wrapped by the lead liquid after cooling, which produces pores, resulting in the unqualified pole terminal. Summary of the invention

[0016] A solution to the problem of bad blowholes in the cast welding of pole terminals comprises the following steps:

[0017] Place multiple pole terminal materials in the material placement slots of the material frame;

[0018] Start the lateral displacement cylinder to push the material frame at the bottom of the displacement slide block to move horizontally to the top of the casting flux box, and start the longitudinal displacement cylinder to drive the material frame to move downward into the casting flux box, so that the material is immersed in the casting flux and the casting flux is dipped;

[0019] After resetting the material frame by activating the longitudinal displacement cylinder again, the transverse displacement cylinder is activated to move the material frame horizontally to the top of the tin liquid tank, and the longitudinal displacement cylinder drives the material frame to go deep into the tin liquid tank to complete the tin liquid dipping;

[0020] After the dipping is completed, the longitudinal displacement cylinder is activated to lift the material frame to the top of the feeding guide plate and the servo motor is turned on. The servo motor drives the deflection block and the material frame to deflect through the output shaft and pour out the material. The material rolls to the alcohol tank through the feeding guide plate;

[0021] Turn on the drive motor to drive the drive shaft to rotate on the drive bearing. The drive shaft drives multiple sets of drive shafts to rotate synchronously through the transverse belt on the double-belt pulley, and drives the guide roller on the guide bearing to rotate through the longitudinal belt on the double-belt pulley, thereby driving multiple materials to move in the alcohol tank through friction, and controlling the soaking time of the materials in the alcohol by controlling the motor speed;

[0022] The soaked materials fall into the collecting frame of the collecting box through the material discharge chute, and then the lifting cylinder is turned on to drive the collecting frame to move up to the discharging chute, and the soaked materials are discharged through the material guide slope on the collecting frame;

[0023] The alcohol in the alcohol tank will be stored at the bottom of the liquid storage tank after passing through the drain holes at the bottom of the aggregate frame, the leakage inner plate and the filter holes at the bottom of the collection drawer. The impurities will remain in the collection drawer, and the alcohol at the bottom of the tank will be pumped out by starting the liquid extraction pump and re-injected into the alcohol tank for circulating soaking.

[0024] The beneficial effects of the present invention are:

[0025] (1) The present invention drives the lateral displacement cylinder and the longitudinal displacement cylinder in the dipping mechanism to move the material at the pole terminal in the material frame to dip into the casting flux and the tin liquid, and drives the material frame to deflect after the dipping is completed by the servo motor, so that the material can be dumped into the alcohol tank. The dipping method is highly efficient and avoids contact between the staff and the casting flux and the tin liquid, thereby greatly improving the practicality and safety of the device.

[0026] (2) The present invention collects the wetted materials into a liquid storage tank through a feeding guide plate and soaks them in alcohol in the tank. During soaking, a plurality of guide rollers are driven to rotate by a driving motor and various belts and pulleys, so that the materials can be moved and transported by the friction between the materials and the motor. The motor speed can be controlled by a control unit, so that the time for the materials to stay and soak in the alcohol tank can be controlled by controlling the speed of the guide rollers. After soaking for a specified time, the casting flux on the surface of the tinned copper parts can be dissolved, because the zinc chloride and phosphorous acid components in the casting flux are easily soluble in alcohol, and alcohol is volatile. When the lead liquid is cast for the tinned bare copper parts after soaking, the presence of zinc chloride + phosphorous acid + pure water on the surface of the materials will be avoided. Under the high temperature of the lead liquid, the reaction is rapid, and a large amount of white gas is produced. A large amount of gas is difficult to be discharged from the outside of the mold in a short time. The gas that is not discharged is wrapped by the lead liquid after cooling, and pores are generated.

[0027] (3) The present invention collects the soaked materials through the collecting frame in the collecting box, and drives it to rise through the lifting cylinder. When it rises to the discharge trough, the alcohol-soaked materials are discharged through the slope, and the alcohol overflowing from the alcohol tank is filtered through the filter holes on the collecting drawer in the liquid storage box. The filtered alcohol is pumped back into the alcohol tank by the liquid pump for recycling, thereby facilitating material unloading while reducing resource damage and further reducing production costs.

[0028] In summary, the present invention has the advantages of high efficiency, low cost and significant effect. BRIEF DESCRIPTION OF THE DRAWINGS
