Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile component manufacturing equipment, in particular to a waste removal device of a continuous power battery shell forming equipment. BACKGROUND

[0002] At present, the application of automobile power batteries is more and more widely, and the power battery needs to be packaged in a battery shell. The battery shell is generally a square barrel-shaped shell obtained by stretching the aluminum plate through the stamping process.

[0003] The stamping die of the battery shell is a progressive stamping die, such as the power battery shell progressive forming die disclosed in Chinese Patent No. CN113500140A. When stamping in the last stage, the waste material at the edge of the semi-finished power battery shell needs to be punched out, and the waste material is a long rectangular thin-walled square frame suspended above the finished battery shell after being punched out. Subsequently, the material advancing device of the stamping equipment clamps the shell body and the waste material of the finished battery shell and continues to move. In the related art, the stamping equipment is provided with a slope at this position, the upper end of the slope is located between the shell body and the waste material, and the lower end extends into the waste material box beside; when the advancing device clamps the shell body and the waste material and moves to this position, the clamp clamping the waste material is loosened, the waste material falls on the slope, and under the action of gravity, the waste material slides into the waste material box along the slope.

[0004] Because the stamping stroke of the die is limited, the distance between the punched waste material and the shell body is not large, so the slope extending between the two has a small slope. As the unloading work continues, the lubrication condition of the surface of the slope becomes worse and worse, and the situation that the waste material cannot successfully slide down by gravity and fails to discharge easily occurs.

[0031] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0032] This application discloses a waste removal device for a continuous power battery casing molding equipment, such as... Figure 1 As shown, the system includes a frame 1, on which a conveying mechanism 3 and a unloading mechanism 4 are mounted. After the final stage of stamping by the progressive die, the battery casing blank is punched into finished casings 2 and scrap 21. Casings 2 have a rectangular barrel shape, while scrap 21 is a rectangular thin-walled frame. The conveying mechanism 3 is used for intermittently and directionally conveying batches of casings 2 and scrap 21, while the unloading mechanism 4 is used to remove and collect the scrap 21.

[0033] like Figure 1As shown, the rack 1 is fixedly provided with a receiving plate 12, the transmission mechanism 3 includes slide rods 31, clamp cylinders 32 and a conveying belt 33, the conveying belt 33 is arranged on the rack 1, and the receiving plate 12 is located directly above the starting end of the conveying belt 33. The slide rods 31 are two and are located on opposite sides of the conveying belt respectively, the two slide rods 31 are synchronously reciprocated on the rack 1, the clamp cylinders 32 are installed on the slide rods 31, the waste 21 separated from the shell 2 is located directly above the shell 2 and maintains a distance with the shell 2; the clamp cylinders 32 are used for clamping the shell 2 and the waste 21, the slide rods 31 are moved to carry the clamp cylinders 32 and the shell 2 and the waste 21 clamped by the clamp cylinders 32 to continue to move to the receiving plate 12, the shell 2 is located below the receiving plate 12, and the waste 21 is located above the receiving plate 12; after the clamp cylinders 32 are loosened, the waste 21 falls on the receiving plate 12, and the shell 2 falls on the conveying belt 33 and is carried by the conveying belt 33 to continue to convey.

[0034] As shown in the figure, Figure 1 The plate surface of the receiving plate 12 facing the waste 21 is inclined to the moving direction of the shell 2, a bent part 121 is fixedly connected to one side edge of the receiving plate 12 along which the shell 2 travels, and when the waste 21 falls on the receiving plate 12, the waste 21 slides along the inclined direction of the receiving plate 12 until the edge of the waste 21 abuts against the bent part 121. The unloading mechanism 4 includes a jet pipe 41, one end of the jet pipe 41 is fixed to one of the slide rods 31, and the nozzle of the jet pipe 41 faces the direction perpendicular to the moving direction of the shell 2 and the waste 21. After the clamp cylinders 32 lower the waste 21, the slide rods 31 are moved, the clamp cylinders 32 move away from the side of the receiving plate 12, and at the same time, the jet pipe 41 moves to the side of the receiving plate 12, and the nozzle of the jet pipe 41 faces the side wall of the waste 21 on the receiving plate 12.

[0035] As shown in the figure, Figure 1 The unloading mechanism 4 further includes guide rods 42, the guide rods 42 are two, one end of the guide rod 42 is fixedly connected to the side of the receiving plate 12 away from the jet pipe 41, the other end of the guide rod 42 is connected to the rack 1, and accommodating grooves 421 are formed on the opposite side walls of the two guide rods 42 along the length direction of the guide rods 42, that is, the shape of the guide rod 42 is similar to that of a channel steel. When the waste 21 abuts against the bent part 121, the waste 21 is located in the extension range of the accommodating grooves 421 along the length direction of the accommodating grooves 421, that is, the airflow sprayed by the jet pipe 41 can push the waste 21 to slide laterally from the receiving plate 12 into the guide rod 42, and the two sides of the waste 21 are located in the accommodating grooves 421 respectively; the guide rods 42 are used for supporting and guiding the sliding direction of the waste 21.

[0036] As shown in the figure, Figure 1 , 2As shown in Figure 3, the guide rail rod 42 includes a fixed section 422 and a discharge section 423. The fixed section 422 is directly connected to the receiving plate 12, and the discharge section 423 is located at the end of the fixed section 422 away from the receiving plate 12, and the discharge section 423 rotates relative to the fixed section 422.

A receiving platform 5 is provided on the frame 1 and directly below the dropping section 423. When the waste material 21 slides to the end of the guide rail rod 42, it abuts against the abutting wedge surface 431 of the deceleration block 43. The elasticity of the deceleration block 43 itself allows the waste material 21 to stop moving quickly and stably, reducing the chance of rebound. At this time, the waste material 21 is completely located within the dropping section 423. Then, the two dropping sections 423 rotate in opposite directions at the same time, and the opening of the receiving groove 421 tilts downward. At this time, the guide rail rod 42 loses its support for the waste material 21, and the waste material 21 can fall naturally to the receiving platform 5.

The drive motor 441 is fixedly connected to the frame 1 and located above the speed reduction block 43. The drive wheel 442 is coaxially connected to the output shaft of the drive motor 441. A force-receiving wheel 4231 is fixedly connected to the end of the dropping section 423 away from the fixed section 422. The axis of the force-receiving wheel 4231 coincides with the rotation axis of the dropping section 423. There are two drive ropes 443, with one drive rope 443 corresponding to each force-bearing wheel 4231. One end of the drive rope 443 is fixedly connected to the wheel surface of the force-bearing wheel 4231, and the other end is fixedly connected to the wheel surface of the drive wheel 442. A reset torsion spring is connected to the rotating shaft between the fixed section 422 and the dropping section 423 (not shown in the figure). The reset torsion spring continuously applies torque to the dropping section 423. In its natural state, the receiving grooves 421 of the fixed section 422 and the dropping section 423 are aligned and connected. After the drive motor 441 is started, the drive wheel 442 rotates and pulls the two drive ropes 443. The two force-bearing wheels 4231 rotate in opposite directions at the same time, and the receiving grooves 421 of the two dropping sections 423 flip downward synchronously to remove the waste material 21. After removal, the drive wheel 442 reverses, and the two dropping sections 423 return to their original posture under the elastic force of the reset torsion spring.
