Referring to fig. 1-5, the arc battery roll forming machine provided by the invention comprises a supporting mechanism 1, a roll forming mechanism 2, a pressing mechanism 3 arranged above the roll forming mechanism 2 and used for stamping a battery to be processed, a positioning piece 4 used for positioning the battery to be processed, and a touch display screen 5 used for adjusting machine parameters by an operator.
The support mechanism 1 includes a base 11, a support plate 12 fixed above the base, a fixing plate 13 fixed to the top end of the support plate 12, and a front panel 14 connected to the support plate 12 and the fixing plate 13.
The rolling mechanism 2 comprises a lower roller support 21 arranged on the base 11, a lower roller 22 arranged on the lower roller support 21, a support member 23 arranged on the base 11, and a first driving member 25 fixed on the support member 23 and connected with the lower roller 22. A decelerator 24 is further provided between the first driving member 25 and the lower roller 22. Two identical rotation sensors 26 and 27 are also provided above the support 23, which are at the same angle and distance from the vertical line of the center of the lower roller, and which cooperate with a first stop 29 fixed to the reducer to define the rotation angle of the lower roller 22. Further, the rotation angle of the lower roller 22 can be adjusted by adjusting the angle between the two rotation sensors and the central vertical line, so as to process batteries with different sizes. The lower roller 22 has a groove 221 formed inwardly on the circumferential surface thereof for accommodating a battery to be processed, and a soft material 28 is provided on the bottom surface of the groove 221.
The pushing mechanism 3 includes a second driving member 31 fixed to the fixing plate 13, a screw rod 33 connected to the second driving member 31 through a coupling 32 for converting the circular motion of the second driving member 31 into a vertical lifting motion, a connecting plate 34 fixed to the screw rod 33, a fixing block 36 fixed to the connecting plate 34, and an upper roller 35 disposed at the bottom of the fixing block 36. The upper roller 35 is sized to mate with the recess 221 of the lower roller and is insertable into the recess 221 to stamp the battery to be processed. The fixing block 36 is connected to the slide rail 15 provided on the front panel 14 through a connecting member 37 provided on the side surface, thereby realizing the movement and positioning of the pressing mechanism 3 in the vertical direction. The connection plate 34 is further provided with a second blocking piece 341, which can limit the vertical movement of the pushing mechanism 3 by cooperating with two identical lifting sensors 38 and 39 provided on the support plate. Two identical vertical face bearings 331 and 332 are respectively arranged at two ends of the screw rod 33, and the vertical face bearings are fixed on an upper fixing piece 16 and a lower fixing piece 17 which are connected with the front panel 14 of the supporting mechanism 1.

In operation, the battery to be processed is first placed in the groove 221 of the lower roller 22, and the positioning member 4 accurately positions the battery to be processed. Then the power supply is started, the upper roller 35 of the pressing mechanism 3 is pressed down under the drive of the second driving member 31, inserted into the groove 221 of the lower roller 22, then the positioning member 4 is removed, the first driving member 25 drives the lower roller 22 to perform reciprocating rotary motion under the cooperation of the rotary inductor, and simultaneously, the second driving member 31 drives the upper roller to perform vertical reciprocating motion under the cooperation of the lifting inductor, and the battery is repeatedly punched.

On the other hand, the soft material 28 disposed in the groove 221 of the lower roller 22 will elastically deform when the upper roller 35 is pressed down, so as to further disperse the stress applied to the battery, and greatly improve the quality and yield of the battery. After repeated rolling for a plurality of times, the battery is processed and molded, the pressing mechanism returns to the initial position, the worker takes away the processed battery, the positioning piece 4 resets, and the processing of the next battery is started.
According to the arc battery roll forming machine provided by the invention, the rotation angle of the lower roller can be changed by adjusting the angle between the two rotation sensors and the central vertical line, and meanwhile, parameters such as the number of times and the strength of the pressing mechanism in a certain time can be changed by adjusting the rotation speed of the second driving piece, the distance between the two lifting sensors and the thickness of the soft material, so that the processing requirements of different types of batteries can be flexibly met.
While the invention has been described in conjunction with the specific embodiments above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, all such alternatives, modifications, and variations are included within the scope of the appended claims.
