DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

As shown in Figures 1 to 8, in at least one embodiment, a welding tape conveying device for a string welding machine is provided, comprising: a conveyor belt 2, the conveyor belt 2 is arranged on a support frame 1; the conveyor belt 2 is suitable for driving the battery cell to move horizontally; the support frame 1 is provided with a feeding rack 10 near the feeding end of the conveyor belt 2, and the welding tape 4 is rolled and rotatably arranged on the feeding rack 10. The welding tape 4 extends from the feeding rack 10 to the direction of the conveyor belt 2 until the welding tape 4 passes through the deflection correction component 3, and the deflection correction component 3 is suitable for placing the welding tape 4 horizontally in the groove of the battery cell. The deflection correction component 3 is arranged above the conveyor belt 2, and the welding tape 4 is suitable for passing through the deflection correction component 3; the deflection correction component 3 includes two trimming pieces 34 arranged opposite to each other, wherein when the welding tape 4 moves horizontally, the trimming piece 34 moves horizontally intermittently to trim the outer wall of the welding tape 4 on both sides. By setting the deviation correction component 3, when the welding strip 4 passes through the positioning plate 31, the trimming piece 34 can intermittently move horizontally to trim the outer wall of the welding strip 4, so that the welding strip 4 can always be located on the center line of the groove of the battery cell, avoiding the phenomenon of the welding strip 4 running off on the battery cell, and improving the quality of welding; when the horizontal movement stroke of the trimming piece 34 is greater than the preset value, resulting in the incision 44 being too large, the enlarged burr 45 drives the linkage piece 37 to move upward, and the nail storage box 40 is suitable for launching fixing nails 42 to the outer wall of the welding strip 4 to fix the upper part of the burr 45 on the welding strip 4.

Referring to FIG. 3 , the deviation correction component 3 includes: a positioning plate 31, the positioning plate 31 is horizontally arranged, the positioning plate 31 is arranged above the conveyor belt 2, the positioning plate 31 is provided with a positioning groove 32 along the length direction, the welding strip 4 is suitable for horizontal movement in the positioning groove 32, and the slot width of the positioning groove 32 is greater than the outer diameter of the welding strip 4. The length direction of the positioning groove 32 is consistent with the conveying direction of the conveyor belt 2; the welding strip 4 described in this embodiment is a circular welding strip 4, and the diameter of the welding strip 4 is less than the width of the groove of the battery cell. Therefore, when the welding strip 4 is placed on the groove of the battery cell, the welding strip 4 will deviate, resulting in the appearance of whitening during welding. In the present embodiment, when the welding strip 4 passes through the positioning plate 31, the trimming piece 34 intermittently cuts an incision 44 on the outer wall of the welding strip 4 from both sides, and the burr 45 of the cut incision 44 will be turned outward, and the turned-up burr 45 will abut against the inner wall of the groove of the battery cell; through such an arrangement, when the welding strip 4 is placed on the groove of the battery cell, the welding strip 4 can always be kept on the center line of the groove, thereby avoiding the occurrence of the welding strip 4 deviation phenomenon.

Furthermore, the inner wall of the discharge port of the positioning groove 32 is provided with an inclined surface 33, and the trimming piece 34 is slidably provided on the inclined surface 33. When the trimming piece 34 moves horizontally along the inclined surface 33, the trimming piece 34 gradually approaches the outer wall of the welding strip 4.

Referring to FIG. 3 , the trimming member 34 includes: a slider 35 and a cutter 36. The slider 35 is vertically arranged and is suitable for intermittently horizontally moving on the inclined surface 33. A driving member is arranged in the positioning plate 31, and the driving member is in transmission connection with the slider 35, and the driving member is suitable for driving the slider 35 to intermittently horizontally move. The driving member is suitable for pushing the slider 35 to intermittently move horizontally along the inclined surface 33, so that the cutter 36 can intermittently cut the outer wall of the welding strip 4. The cutter 36 is obliquely arranged on the side wall of the slider 35, and the cutting edge of the cutter 36 faces the welding strip 4; wherein, when the slider 35 intermittently moves horizontally, the cutter 36 intermittently cuts the outer wall of the welding strip 4, so that the burrs 45 after cutting are turned over toward the outer wall direction of the positioning groove 32.

Referring to Figure 7, the slider 35 moves horizontally along the inclined surface 33 until the cutting edge of the cutter 36 abuts against the outer wall of the welding strip 4. As the slider 35 continues to move, the cutter 36 is suitable for cutting the outer wall of the welding strip 4 to form a notch. At the same time, the welding strip 4 separated by the cutter 36 will form a burr 45 on its outer side. The burr 45 is pushed to turn outward by the cutter 36. After the welding strip 4 moves horizontally from the positioning plate 31 to the battery cell, the burr 45 is suitable for abutting against the side wall of the groove of the battery cell; the cutter 36 intermittently cuts the welding strip 4, so that each burr 45 limits the welding strip 4 from both sides to prevent it from deviating in the groove of the battery cell.

Refer to Figure 6. A linkage piece 37 is slidably provided on the inner wall of the positioning groove 32. The linkage piece 37 is provided at the discharge end of the positioning groove 32. The linkage piece 37 is suitable for contacting with the burr 45 of the welding strip 4. A return spring is fixed in the positioning groove 32. One end of the return spring is fixed on the linkage piece 37. The return spring is suitable for pulling the linkage piece 37 to retract it into the positioning plate 31. When the burr 45 cut by the cutter 36 moves horizontally between the two linkage pieces 37, the outer wall of the burr 45 contacts the inner wall of the linkage piece 37. At this time, the burr 45 will not push the linkage piece 37 to slide outward.

Referring to Figure 8, when the driving member pushes the cutter 36 to move horizontally for a stroke greater than the normal stroke range, at this time, the notch cut by the cutter 36 on the outer wall of the welding strip 4 is larger than the normal range, and the burr 45 is turned outward by a distance greater than the normal range. When the burr 45 passes between the two linkage pieces 37, the burr 45 is suitable for pushing the linkage piece 37 to slide outward, and the linkage piece 37 protrudes from the positioning plate 31 until the inner end side wall of the linkage piece 37 is separated from the connecting tube 41, and the nail storage box 40 is suitable for conveying fixing nails 42 into the connecting tube 41, and the fixing nails 42 are suitable for fixing the burr 45 on the welding strip 4.

Referring to Figure 3, the correction component 3 also includes an adjustment member 38, which is arranged along the width direction of the positioning plate 31, and the adjustment member 38 is linked with the driving member; wherein, after the driving member is pushed by the burr 45 to protrude outward from the positioning plate 31, the adjustment member 38 is suitable for generating fixing nails 42 on the outer wall of the welding strip 4 to fix the upper part of the burr 45 on the welding strip 4.

6 , the adjusting member 38 comprises: a fixing frame 39, which is arranged above the positioning plate 31; a nail storage box 40, wherein the two nail storage boxes 40 are respectively fixed at the two ends of the fixing frame 39; a connecting pipe 41, which passes through the positioning plate 31 and is suitable for connecting the nail storage box 40 with the positioning groove 32; a sensor is arranged at the end of the connecting pipe 41 close to the linkage piece 37, and a control module is arranged in the nail storage box 40, and the control module is connected with the sensor by electrical signals. When the linkage piece 37 moves outward and the linkage piece 37 is separated from the connecting pipe 41, the sensor detects that the linkage piece 37 is pushed outward by the burr 45, and the control module is suitable for controlling the driving unit in the nail storage box 40, and the driving unit is suitable for driving the fixing nail 42 in the nail storage box 40 so that it passes through the connecting pipe 41 toward the outer wall of the welding strip 4, and the fixing nail 42 is suitable for fixing the upper part of the burr 45 on the outer wall of the welding strip 4, thereby preventing the burr 45 from turning outward too much. The nail storage box 40 is suitable for launching the fixing nails 42, so that the fixing nails 42 pass through the connecting pipe 41 and are fixed on the outer wall of the welding strip 4. The axis of the connecting pipe 41 is arranged at the upper part of the axis of the welding strip 4.
