[0028] Please refer to Figures 1-3 The two cutting-off plates 3 fixed to the bottom of the fixed plate 2 and the two cutting-off plates 3 fixed to the top of the fixed plate 2 are clamped to the upper end and the lower end of the lead belt 1 respectively, the fixed plate 2 clamped to the upper end of the lead belt 1 and the fixed plate 2 clamped to the lower end of the lead belt 1 are staggered relative to the lead belt 1, so that the two cutting-off plates 3 fixed to the bottom of the fixed plate 2 shape and cut off the burrs 101 on the two side edges of the upper end of the lead belt 1, and the two cutting-off plates 3 fixed to the top of the fixed plate 2 shape and cut off the burrs 101 on the two side edges of the lower end of the lead belt 1, which not only can ensure that the cutting-off forces in the upper and lower directions can act on the lead belt more evenly during the trimming process, thereby realizing more uniform trimming effect, helping to reduce the residual burrs and improve the surface quality of the trimmed lead belt, but also can ensure that the lead belt is clamped stably during the trimming process, helping to prevent the lead belt from deviating or sliding during the trimming process, and effectively improving the accuracy and stability of the trimming.

[0029] The working principle and use process of the utility model are as follows: Figures 1-7As shown, after the lead strip side edge burr trimming device is assembled, the operator installs the device on the grid manufacturing equipment (the functions and structures of conventional equipment such as the grid manufacturing equipment are well known in the art, and the connection settings are also well known, so this will not be described in detail, and the grid manufacturing equipment is not shown in the drawings), that is, the fixed plate 2 clamped on the upper end of the lead strip 1 is fixed on the upper part of the lead strip conveying device (the functions and structures of conventional equipment such as the lead strip conveying device are well known in the art, and the connection settings are also well known, so this will not be described in detail, and the lead strip conveying device is not shown in the drawings) in the grid manufacturing equipment, and the fixed plate 2 clamped on the lower end of the lead strip 1 is fixed on the lower part of the lead strip conveying device in the grid manufacturing equipment, so that the two are staggered relative to the lead strip 1.

[0030] When the burrs 101 on both sides of the lead strip 1 need to be trimmed, the operator first clamps the upper end of the lead strip 1 between the two cutting plates 3 fixed on the bottom of the fixed plate 2, so that the burrs 101 on both sides of the upper end of the lead strip 1 are cut off under the shaping of the two cutting plates 3, and the lower end of the lead strip 1 is clamped between the two cutting plates 3 fixed on the top of the fixed plate 2, so that the burrs 101 on both sides of the lower end of the lead strip 1 are also cut off under the shaping of the two cutting plates 3. Specifically, the lead strip 1 is first horizontally moved and transmitted by the lead strip conveying device (the transmission direction of the lead strip is shown by the arrow direction in Figure 1 The wedge surface 401 and the arc surface 402 of the shaping block 4 integrally formed with the cutting plate 3 gradually increase the contact area with the side edge of the lead strip 1, so that the vertical extension burrs 101 (i.e. perpendicular to the surface of the lead strip) on both sides of the lead strip 1 are gradually adjusted to horizontal extension burrs 101 (i.e. horizontal to the surface of the lead strip) under the lead strip 1 horizontal movement and the wedge surface 401 and the arc surface 402 resistance, and then the lead strip 1 will continue to move horizontally until the horizontal extension burrs 101 come into contact with the cutting edge 501 of the cutting block 5. Since the cutting edge 501 is vertically arranged relative to the horizontal extension burrs 101 on the lead strip 1, the horizontal extension burrs 101 are cut off from the side edge of the lead strip 1 by the cutting edge 501 when they come into contact with the cutting edge 501 in the vertical direction, so that the lead strip 1 becomes smooth on both sides due to the cutting of the burrs 101 (as shown in Figure 1The lead belt side edge burr trimming device is arranged at the right end of the lead belt (as shown in the rightmost end of the lead belt), thereby solving the defects of the lead belt 1 in subsequent processing caused by burr residues, such as perforation and delamination, and significantly improving the product quality and service life of the lead-acid storage battery.
