Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a material strip terminal cutting device. Background Technology

[0002] Terminal strips consist of a series of terminals arranged in a standard pitch. During production, the equipment cuts the terminals from the strip and then crimps them onto the workpiece to complete product manufacturing. For terminal crimping, the terminals must first be separated from the strip before being fed into the crimping mechanism. After the strip is cut by the blade, burrs are formed at the cut point. As the strip is conveyed forward, these burrs can encounter the cutting wall of the bottom blade, causing the strip to become blocked and unable to be conveyed properly. Summary of the Invention

[0003] According to an embodiment of the present invention, a material strip terminal cutting device is provided for cutting material strips, comprising: a bottom blade and a cutting blade;

[0004] The bottom cutter has a first surface and a second surface. A receiving groove is provided on the first surface of the bottom cutter. A slit is provided at the bottom of the receiving groove. The slit extends through the bottom of the receiving groove to the second surface of the bottom cutter. The second surface of the bottom cutter has a misalignment plate. The misalignment plate is located on the side of the second surface closer to the material strip. The edge of the misalignment plate is on the same plane as the side wall of the slit. The cutter is set to correspond to the slit. The vertical distance between the misalignment plate and the second surface of the bottom cutter is not less than the length of the burr produced by the cutter cutting the material strip.

[0005] Furthermore, a guide hole is provided on the bottom cutter, and the guide hole is set at the position of the cut, with the guide hole and the cut on the same straight line.

[0006] Furthermore, the cutter includes: a blade body, a blade head, and a guide plate;

[0007] One end of the blade body is connected to the cutter head and the guide plate. The cutter head is set to correspond to the cutting edge, and the guide plate is set to correspond to the guide hole. The length of the guide plate is greater than the length of the cutter head.

[0008] Furthermore, the second surface of the bottom cutter has a stepped surface, which is provided at the cut, and the stepped surface is concave inward along the conveying direction of the material belt.

[0009] Furthermore, a guide groove is provided on the second surface of the bottom cutter, which is used to guide the material strip.

[0010] Furthermore, the guide groove is V-shaped and located between the two cuts.

[0011] According to an embodiment of the present invention, a material strip terminal cutting device is provided. During the conveying process, the material strip moves along the surface of the misalignment plate to the cutting edge. The cutter cuts off the terminal of the material strip, and burrs are generated on the material strip. Since there is a certain misalignment distance between the misalignment plate and the second surface of the bottom cutter, the burrs will not hit the side wall of the subsequent cutting edge during the movement of the material strip, effectively avoiding the phenomenon of blockage of the material strip during the conveying process.

[0012] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

Detailed Implementation

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0021] like Figures 1-6 As shown, a material strip terminal cutting device according to an embodiment of the present invention is used to cut material strips, including: a bottom knife 1 and a cutting knife 2;

[0022] The bottom blade 1 has a first surface and a second surface. A receiving groove 11 is provided on the first surface of the bottom blade 1. A cut 12 is provided at the bottom of the receiving groove 11. The cut 12 extends through the bottom of the receiving groove to the second surface of the bottom blade 1. The second surface of the bottom blade 1 has a misalignment plate 13. The misalignment plate 13 is located on the side of the second surface closer to the material strip. The edge of the misalignment plate 13 is on the same plane as the side wall of the cut 12. The cutter 2 is set corresponding to the cut 12. The vertical distance between the misalignment plate 13 and the second surface of the bottom blade 1 is not less than the length of the burr generated by the cutter 2 when cutting the material strip.

[0023] During the conveying process, the material strip moves along the surface of the misalignment plate 13 to the cut 12. The cutter 2 cuts off the terminals of the material strip, and burrs will be generated on the material strip. Since there is a certain misalignment distance between the misalignment plate 13 and the second side of the bottom cutter 1, the burrs will not hit the side wall of the cut 12 behind the material strip during the movement, effectively avoiding the phenomenon of blockage of the material strip during the conveying process.

[0024] like Figures 1-6 As shown, a guide hole 14 is provided on the bottom knife 1. The guide hole 14 is set at the position corresponding to the cut 12, and the guide hole 14 and the cut 12 are on the same straight line.

[0025] The cutter 2 includes: a cutter body 21, a cutter head 22, and a guide plate 23;

[0026] One end of the blade body 21 is connected to the blade head 22 and the guide plate 23. The blade head 22 is set to the cut 12, and the guide plate 23 is set to the guide hole 14. The length of the guide plate 23 is greater than the length of the blade head 22.

[0027] When the cutter 2 is to cut the strip, the guide plate 23 is first inserted into the guide hole 14 so that the cutter head 22 can be smoothly inserted into the cut 12, ensuring the stability of the strip cutting.

[0028] like Figures 1-4 As shown, the second surface of the bottom cutter 1 has a stepped surface 15, which is provided at the cut 12. The stepped surface 15 is concave inward along the conveying direction of the material belt. A guide groove 16 is provided on the second surface of the bottom cutter 1 to guide the material belt. The guide groove 16 is V-shaped and is located between the two cuts 12.

[0029] The guide chute 16 can guide the conveying direction of the material belt, avoiding misalignment of the conveying direction caused by the material belt being cut.

[0030] Above, refer to Figures 1-6This invention describes a tape terminal cutting device according to an embodiment of the present invention. During the conveying process, the tape moves along the surface of the misalignment plate 13 to the cut 12. The cutter 2 cuts off the terminal of the tape, and burrs are generated on the tape. Since there is a certain misalignment distance between the misalignment plate 13 and the second surface of the bottom cutter 1, the burrs will not hit the side wall of the cut 12 during the movement of the tape, effectively avoiding the phenomenon of tape blockage during the conveying process.
