Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1, an embodiment of an adjustable cushion plate mechanism for a battery cell two-sealing machine according to the present invention includes a battery cell cushion plate 10 and an adjusting plate 20, and the distance between the two plate members is adjusted to achieve the purpose of adjusting the overall thickness of the two-sealing machine cushion plate, in this embodiment, the battery cell cushion plate 10 is disposed above the adjusting plate 20, and a battery cell is positioned on the battery cell cushion plate 10, so that the battery cell cushion plate 10 has no displacement except for moving in the up-down direction, and in order to adjust the distance between the two plate members, the lower surface of the battery cell cushion plate 10 and the upper surface of the adjusting plate 20 are respectively provided with a wedge 30 that is mutually matched, the wedge 30 on the lower surface of the battery cell cushion plate 10 is opposite to the inclined plane of the wedge 30 on the upper surface of the adjusting plate 20, the adjusting plate 20 is placed on a fixing bracket, so that the height of the adjusting plate 20, adjusting part 40 drive adjusting plate 20 is along the inclined plane direction horizontal migration of its last wedge 30, at this moment, on electric core backing plate 10 not with the basis of adjusting plate 20 syntropy removal, electric core backing plate 10 is kept upwards or is removed downwards in the top on the inclined plane of wedge 30, in this embodiment, in order to improve the stability between electric core backing plate 10 and the adjusting plate 20, electric core backing plate 10 back and the positive wedge 30 of adjusting plate 20 are provided with many pairs, specifically are provided with 5 pairs, when guaranteeing the angle of wedge 30, make the angle of wedge 30 be unlikely to too high, and electric core backing plate 10 is supported evenly simultaneously, ensures the stability of electric core backing plate 10. The battery cell base plate 10 is connected with the fixed support in a vertical sliding mode through the guide assembly 50, so that the battery cell base plate 10 can move up and down freely and cannot move in the horizontal direction. Further, in this embodiment, the adjusting assembly 40 includes an adjusting screw 41, the adjusting screw 41 is disposed along the moving direction of the adjusting plate 20, the nut end of the adjusting screw 41 is rotatably connected to the adjusting plate 20, and the other end of the adjusting screw 41 is rotatably fixed on the fixing bracket. Because the length direction of the adjusting screw 41 is consistent with the moving direction of the adjusting plate 20, when the adjusting screw 41 is screwed in or out in the direction of the fixing bracket, the adjusting plate 20 moves horizontally along with the adjusting screw 41, and then the cell cushion plate 10 moves up and down along the inclined plane of the wedge block 30 on the adjusting plate 20, thereby realizing the adjustment of the height of the cushion plate. Since the adjusting plate 20 is a flat plate structure, which is not convenient for connecting the adjusting screw 41, in this embodiment, the adjusting assembly 40 further includes a mounting plate 42, the mounting plate 42 is perpendicular to the plane of the adjusting plate 20 and is connected to one end of the adjusting plate, so that the adjusting screw 41 can pass through the mounting plate 42 and be rotatably connected to the mounting plate, the adjusting screw 41 is rotatably connected to the mounting plate 42, the adjusting screw 41 can not be screwed into or out of the fixing bracket, and meanwhile, the adjusting screw 41 can be moved to drive the mounting plate 42 to move, thereby driving the adjusting plate 20 to move. For reducing the friction between regulating plate 20 and the fixed, conveniently drive regulating plate 20, be provided with horizontal guide on the fixed bolster of regulating plate 20 below, regulating plate 20 sliding connection in horizontal guide.
Referring to fig. 1, fig. 2 and fig. 3, for the utility model discloses guide assembly 50 structure sketch map, guide assembly 50 includes guide pillar 51, guide pillar 51 one end is passed regulating plate 20 and electric core backing plate 10, the guide pillar 51 other end is fixed in on the fixed bolster, regulating plate 20 with guide pillar 51's department of meeting is waist type hole 21, waist type hole 21 with the moving direction of electric core backing plate 10 is unanimous. Because guide pillar 51 one end is fixed in the fixed bolster, and guide pillar 51 passes electric core backing plate 10, therefore electric core backing plate 10 can only follow guide pillar 51 axial displacement, can not produce the displacement on the plane, and waist type hole 21's setting on regulating plate 20, make regulating plate 20 still can follow the length direction removal in waist type hole 21, under the drive of regulating assembly 40, regulating plate 20 translation, electric core backing plate 10 moves under guide pillar 51 under holding on the top of wedge 30, waist type hole 21's length has restricted regulating plate 20's displacement distance, guarantee that wedge 30 of electric core backing plate 10 lower surface and the wedge 30 of regulating plate 20 upper surface cooperate all the time, prevent that wedge 30 from misplacing. Further, in order to ensure that the cell cushion plate 10 slides smoothly along the guide post 51 and reduce friction between the guide post 51 and the cell cushion plate 10, a guide sleeve 52 is disposed on the cell cushion plate 10, and the guide post 51 penetrates through the guide sleeve 52.
Referring to fig. 4, a push plate 11 and a limit baffle 12 are further respectively disposed on two sides of the cell pad plate 10, and the push plate 11 is movably disposed on one side of the cell pad plate 10 and is parallel to the limit baffle 12. The push pedal 11 will be placed the electric core on electric core backing plate 10 and push to limit baffle 12 location, and electric core side lower part butt limit baffle 12 waits that the banding stretches out limit baffle 12 and takes and put in low head upper surface, adjusts electric core backing plate 10 highly makes the lower surface of waiting the banding and the upper surface of low head be in same height, utilizes the low head to carry out the heat-seal. Because the height of treating the banding during the heat-seal is highly unanimous with the low head, is difficult for appearing the seal after two sealings are accomplished, and unsmooth phenomenon can not appear in the region that two banding and electric core both ends top seal overlap, has ensured the effect of electric core heat-seal, and then guarantees the quality of electric core and the whole outward appearance of electric core. In this embodiment, the push plate 11 may be disposed on the fixing support, or may be disposed on the electrical core backing plate 10, and the push plate 11 is driven by an air cylinder or a motor.
