Description

Technical Field

[0001] The invention relates to the field of lead-acid battery manufacturing, and in particular to a burr removal structure for a lead-acid battery grid. Background Art

[0002] As the most economical and environmentally friendly way to produce grids, the continuous casting technology for lead-acid battery grids has been widely recognized by lead-acid battery manufacturers.

[0003] Lead-acid battery grids are produced by continuous casting, which uses a rotating mold (rotating mold) and a fixed mold (fixed mold) to flush the lead liquid through the fixed mold into the cavity where the rotating mold and the fixed mold are in contact. After the rotating mold rotates away from the fixed mold, it is cooled and shaped, and then the grid is pulled out. Due to the uncontrollability of casting itself, and the mechanical processing errors and deformation differences after heating between the rotating mold and the fixed mold, the gap between the two is too large or the fit is uneven, and the continuously cast lead-acid battery grid will have defects such as burrs and burrs, which will affect the coating of lead paste during subsequent plate production and reduce the contact area between the lead paste and the grid, thereby affecting the battery performance. At the same time, during the continuous casting process, lead oxide will gradually accumulate on the surface of the rotating mold, and foreign matter such as oil stains will also affect the forming quality of the grid. The traditional grid is cooled and then burrs are removed. The burrs become harder after cooling, which increases the difficulty of removal and the overall removal effect is not good.

[0004] Therefore, in order to solve the above problems, a lead-acid battery grid strip burr removal structure is needed to solve the above production problems. Summary of the invention

[0005] In view of this, the lead alloy grid burr removal device of the present technical solution is arranged between the grid exiting the fixed mold and separating from the rotating mold, and adopts a rotating brush wheel method to rotate rapidly to remove burrs and burrs on the surface of the grid. At the same time, it can also remove foreign matter such as lead oxide and oil accumulated on the surface of the rotating mold, thereby improving the surface quality of the grid and facilitating subsequent product production.

[0006] A lead alloy grid burr removal device comprises a burr removal mechanism arranged on a mold base plate, wherein the burr removal mechanism is arranged between the grid fixed mold and the grid traction roller, and the burr removal mechanism is used to cooperate with the grid to remove surface burrs.

[0007] Furthermore, the burr removal mechanism includes a positioning plate installed in conjunction with the mold substrate, a driving motor installed in conjunction with the positioning plate, and a wheel brush assembly installed on the mold substrate, and the power output end of the driving motor is installed in conjunction with the wheel brush assembly and provides power input.

[0008] Furthermore, the wheel brush assembly includes a positioning seat arranged below the mold substrate, a wheel brush mounting seat installed in conjunction with the positioning seat, and a wheel brush shaft rotatably installed in conjunction with the wheel brush mounting seat, and the output end of the drive motor is connected and installed in conjunction with the wheel brush shaft.

[0009] Furthermore, a wheel brush is installed on the outer sleeve of the wheel brush shaft, and the wheel brush includes a middle wheel brush and an outer wheel brush arranged in the middle of the wheel brush shaft, and the outer wheel brush includes a left wheel brush and a right wheel brush arranged symmetrically relative to the middle wheel brush.

[0010] Furthermore, the left wheel brush and the right wheel brush have the same structure, and the radius of the left wheel brush is larger than the radius of the middle wheel brush.

[0011] Furthermore, a coupling is provided between the wheel brush rotating shaft and the output shaft of the driving motor.

[0012] The beneficial effects of the present invention are:

[0013] 1. The installation position of the whole device should be between the grid exiting the fixed die and the grid leaving the rotating die. The burrs and burrs on the grid at this position have not been completely cooled and are easy to remove.

[0014] 2. The device is located between the grid exiting the fixed mold and separating from the rotary mold. At this position, the grid body is embedded in the rotary mold cavity and has not yet completely protruded from the outer circle of the rotary mold. The burrs and burrs are outside the grid body and protrude from the outer circle of the rotary mold. When removing the burrs and burrs, the grid body will not be damaged.

[0015] 3. Because the burrs and burrs protrude from the outer circle of the rotating mold, the back of the grid is supported, which makes it easier to remove. If there is no support, the burrs and burrs will be bent when the removal device is working, but it is not easy to brush off;

[0016] 4. Use the brush wheel method, which can better dynamically fit the outer circle of the rotating mold and better remove the burrs and edges attached to the outer circle of the rotating mold;

[0017] 5. The wheel brush method can simultaneously remove foreign matter such as lead oxide and oil accumulated on the surface of the rotating mold, thereby improving product quality;

[0018] 6. When using the wheel brush method, you can replace the wheel brushes of different materials and structures according to the different grid alloys and forming states, including nylon brushes, wire brushes, etc., to achieve different rolling brush effects.

[0019] 7. The driving motor adopts a servo motor, which can match different speeds and directions according to requirements and roller brush effects, and realize forward and reverse rotation of the wheel brush at different speeds.

[0020] 8. The servo motor and the wheel brush are connected through an expansion sleeve coupling, which ensures the stability of the transmission and cuts off the power in the event of an abnormal jam of the wheel brush, thus protecting the rotating mold surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In this embodiment, the burr removal mechanism includes a positioning plate 8 installed in cooperation with the mold substrate 1, a driving motor 7 installed in cooperation with the positioning plate 8, and a wheel brush assembly installed on the mold substrate 1. The power output end of the driving motor 7 is installed in cooperation with the wheel brush assembly and provides power input. The positioning plate 8 is fixedly installed on the side of the mold substrate 1 to provide a mounting position for the driving motor. The driving motor adopts a servo motor, which can match different speeds and directions according to requirements and rolling brush effects to achieve forward and reverse rotation of the wheel brush at different speeds.

[0027] In this embodiment, the wheel brush assembly includes a positioning seat 9 arranged below the mold substrate 1, a wheel brush mounting seat 10 installed in conjunction with the positioning seat 9, and a wheel brush shaft 12 rotatably installed in conjunction with the wheel brush mounting seat, and the output end of the drive motor is connected and installed in conjunction with the wheel brush shaft 12. The positioning seat 9 is fixedly installed on the lower surface of the mold substrate 1, and the wheel brush mounting seat 10 is connected and installed in conjunction with the positioning seat 9. The wheel brush mounting seat 10 is two mutually parallel arrangements for rotatably mounting the wheel brush shaft 12. The output end of the drive motor 7 provides power input for the wheel brush shaft 12. Preferably, a spring structure or elastic member can also be provided between the wheel brush mounting seat 10 and the positioning seat 9, so that the wheel brush shaft 12 can provide an elastic contact effect with the grid when in use, thereby further improving the burr removal effect.
