The moving seat 52 can be movably arranged in the Y direction or the reverse side of the Y direction of the support frame 51 along the Y direction; the limit block 53 can be movably arranged in the upper part of the moving seat 52 along the vertical direction, the first driving member 54 is used to drive the moving seat 52 to move along the Y direction, and the second driving member 55 is connected between the moving seat 52 and the limit block 53 to drive the limit block 53 to move along the vertical direction; the upper part of the limit block 53 facing the side of the support frame 51 is provided with a first inclined surface 531, the inclination of the first inclined surface 531 is 30-60 degrees, and the lower surface of the limit block 53 is provided with a heating plate 533;

[0052] A cutting mechanism 8, which is disposed between the guide support seat 4 and the adhesive bonding mechanism 5 and is used to cut off the adhesive tape body 11;

[0053] In the first state, the first inclined surface 531 of the limit block 53 moves to be in the same plane as the inclined guide edge 41;

[0054] In the second state, after the tape body 11 is pressed by the pressing roller group 3, it is guided to the support platform 511 by the guide support seat 4, and the folded edge 111 of the tape body 11 abuts against the first inclined surface 531;

[0055] In the third state, the cutting mechanism 8 cuts off the tape body 11 at a position between the guide support seat 4 and the glue sticking mechanism 5;

[0056] In the fourth state, one side of the U-shaped steel belt 9 moves to the tape body 11 pressed against the support platform 511 and positioned;

[0057] In the fifth state, the limiting block 53 is controlled to move inward and downward successively, so that the folded edge 111 of the tape body 11 is guided inward, and the folded edge 111 of the tape body 11 is pressed against the surface of the steel belt 9 through the lower surface of the limiting block 53 .

[0058] The automatic tape attaching method of the above battery clamp automatic tape attaching machine structure comprises the following steps:

[0059] Step 1: The guide roller set 2 leads the tape body 11 in the tape roll 1; the first inclined surface 531 of the control limit block 53 moves to the same plane as the inclined guide edge 41; (this is the first state)

[0060] Step 2: The tape body 11 is pressed and guided by the pressing roller group 3, so that the two sides of the tape body 11 passing between the upper pressing roller 31 and the lower pressing roller 32 form a folded edge 111 bent upward by 30-60 degrees;

[0061] Step 3: The tape body 11 passing through the embossing roller set 3 is extended to the support platform 511 of the gluing mechanism 5 to a fixed length under the guidance of the guide support seat 4, and the folded edge 111 of the tape body 11 abuts against the first inclined surface 531; (this is the second state)

[0062] In this step, a position sensor or a photoelectric sensor may be provided on the frame to sense the conveying position of the tape body 11. When the end of the tape body 11 reaches a predetermined position of the support platform 511, the guide roller group 2 and the pressing roller group 3 are controlled to stop working.

[0063] Step 4: Control the cutting mechanism 8 to cut the tape body 11 at the position between the guide support seat 4 and the glue sticking mechanism 5; (this is the third state)

[0064] Step 6: Move one side of the U-shaped steel belt 9 to the tape body 11 pressed against the support platform 511 for positioning; (this is the fourth state)

[0065] Step 7: Control the limit block 53 to move inward and downward successively under the drive of the first driving member 54 and the second driving member 55, so that the folded edge 111 of the tape body 11 is guided inward, and the folded edge 111 of the tape body 11 is pressed against the surface of the steel belt 9 through the lower surface of the limit block 53. (This is the fifth state)

[0066] In the above implementation mode, it should be noted that the steel belt 9 clamp is still a semi-finished product, i.e., a U-shape, when the tape is applied. Later, the two ends of the U-shaped steel belt need to be bent and welded to form a frame-shaped clamp. These are the existing technologies for making the steel belt 9, and reference can be made to Figure 11 of the Chinese patent disclosed in CN216335741U.

[0067] As a preferred embodiment, a second inclined surface 532 is provided at a lower portion of the limiting block 53 facing the supporting frame 51 .

[0068] In the above embodiment, in step 7 (fifth state), the limiting block 53 can better guide the folded edge 111 of the tape body 11 to be bent inwardly and covered on the surface of the steel strip 9 through the second inclined surface 532 during movement.

[0069] As a preferred embodiment, a heating guide platform 6 is provided between the guide roller group 2 and the embossing roller group 3, and a heating strip 61 is provided on the upper surface of the heating guide platform 6. The position of the heating strip 61 is the corner position of the folding edge 111 of the tape body 11, and the temperature of the heating strip 61 is 40-45°C.

[0070] Reference Figure 6 When the tape body 11 passes through the heating guide platform 6, the corner of the lower part of the tape body 11 that needs to be bent to form the folded edge 111 will be heated by the heating strip 61, so that when it passes through the embossing roller group 3 later, the corner is heated and softened, making it easier to form the folded edge 111 that bends upward.

[0071] As a preferred embodiment, a heating plate 533 is provided on the lower surface of the limiting block 53, and the heating temperature of the heating plate 533 is 50-55°C.

[0072] In step 7 (fifth state), when the folded edge 111 of the tape body 11 is pressed against the surface of the steel belt 9 by the lower surface of the limit block 53, the heating plate 533 enables the tape body 11 to fit more closely to the surface of the steel belt 9 to avoid falling off.

[0073] As a preferred embodiment, an anti-sticking guide limiter 7 is provided on the X-direction side of the upper pressure roller 31, and the anti-sticking guide limiter 7 is connected to the frame. A guide plane 71 is provided at the lower part of the anti-sticking guide limiter 7, and the X-direction reverse side of the guide plane 71 extends to near the lower end of the upper pressure roller 31, and a vertical plane 72 is provided on the X-direction side of the anti-sticking guide limiter 7 for limiting the end of the steel belt 9.

[0074] In the above embodiment, since the upper pressing roller 31 presses the tape body 11, the upper part of the tape body 11 is easily adhered to the surface of the upper pressing roller 31, and the guide plane 71 of the anti-sticking guide limiter 7 can guide the tape body 11 after pressing in the X direction, and the vertical plane 72 is used to position the end of the U-shaped steel strip 9 in step 6 (the fourth state), referring to Figure 2 .

[0075] As a preferred embodiment, the first driving member 54 includes a bidirectional screw 541 with an axial direction in the Y direction and a limiting guide column 542, and the two movable seats 52 are respectively provided with a nut threadedly matched with the bidirectional screw 541 and a guide sleeve slidingly matched with the limiting guide column 542, and also include a driving motor 543 transmission connected to the bidirectional screw 541.

[0076] In the above implementation mode, refer to Figure 5 As long as the driving motor 543 is controlled to rotate and drive the bidirectional screw 541 to rotate, the two moving seats 52 can be controlled to move synchronously in opposite directions, thereby driving the two limit blocks 53 to move.

[0077] As a preferred embodiment, the second driving member 55 is a cylinder, a hydraulic cylinder or an electric cylinder.

[0078] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
