A plurality of terminals are arranged in a row, and the lead frame is connected to both sides. The purpose of cutting is to cut off the lead frame, separate the lead frame from the terminals, obtain a plurality of independent terminals, and finally collect the terminals into a strip-shaped packaging strip. The problem is that manual cutting of the lead frame not only has low efficiency but also is not convenient for quickly collecting a plurality of terminals into the packaging strip. Summary of the Utility Model

[0003] To solve the deficiencies of the prior art, the utility model provides a cutting device for terminals and lead frames, which can automatically cut off the lead frame and is convenient for collecting the terminals.

[0004] To achieve the purpose of the utility model, the following scheme is proposed:

[0005] A cutting device for terminals and lead frames includes a power mechanism, a cutting mechanism, and a cutting groove.

[0006] The cutting groove is arranged at the top of the base. The cutting groove is used to accommodate the terminals. The lead frame connected to the terminals is supported on the top of the side wall of the cutting groove. Both ends of the cutting groove are open, and a rectangular frame is arranged at one end. The open end of the packaging strip is used to be inserted into the rectangular frame.

[0007] The cutting mechanism includes a cutter and a plurality of guide rods arranged on the top of the cutter. The guide rods penetrate upward through the bracket. The bracket is arranged on the base. A spring is arranged on the outer periphery of the guide rod. Both ends of the spring are respectively connected to the bracket and the cutter. The cutter is located above the cutting groove and is used to cut off the lead frame.

[0008] The power mechanism is arranged on the bracket and is used to control the up and down movement of the cutter.

[0009] Further, a plurality of bases are sequentially arranged on the top of the cutter along the long axis direction of the cutter. A roller is rotatably arranged on the base. The power mechanism includes a motor, a rotating shaft, and a plurality of driving blocks. The end of the rotating shaft is rotatably connected to the bracket. The motor is used to drive the rotating shaft. The plurality of driving blocks are sequentially arranged on the rotating shaft. The side surface of the driving block is closely attached to the side surface of the corresponding roller. The side surface of the driving block sequentially includes a first arc surface, a first plane, a second arc surface, and a second plane. The centers of the first arc surface and the second arc surface are located on the axis of the rotating shaft. The radius of the first arc surface is smaller than the radius of the second arc surface. When the second arc surface is closely attached to the side surface of the roller, it is used to cut off the lead frame by the cutter.

[0010] Further, a total of four guide rods are provided. Two flat plates are arranged on each side of the cutter. The guide rods are arranged on the top of the corresponding flat plates.

[0011] Further, a circular plate with a diameter larger than its own is provided at the top of the guide rod.

[0012] Further, the top of the side wall of the base is set as an inclined surface, and this inclined surface is used for the lead frame to slide down.

[0013] The beneficial effects of the utility model are as follows: The connection body of the terminal and the lead frame is placed in the slitting groove. Through the cooperation of the power mechanism and the slitting mechanism, the lead frame can be automatically cut off, and the separation of the lead frame and the terminal is completed, solving the problem of manually cutting the lead frame. After slitting, the terminals are arranged in the slitting groove. First, insert the open end of the packaging strip into one end of the slitting groove, and then all the terminals can be directly pushed into the packaging strip with the help of tools, thus completing the collection and packaging of the terminals. The operation is simple and fast, without the need to pick up the terminals one by one manually and put the terminals into the packaging strip. Description of the Drawings

[0018] As Figure 2 shown, this embodiment provides a slitting device for a terminal and a lead frame, including a power mechanism 1, a slitting mechanism 2, and a slitting groove 3.

[0019] Specifically, the slitting groove 3 is set as a strip structure, and the slitting groove 3 is fixedly arranged at the top of the base 31. Before slitting, the slitting groove 3 is used to accommodate the terminals, and the lead frame connected to the terminals is supported on the top of the side wall of the slitting groove 3. After slitting, the terminals will remain in the slitting groove 3, while the lead frame will fall outside the slitting groove 3. In order to facilitate the sliding of the lead frame and prevent the lead frame from accumulating around the slitting groove 3 and affecting the subsequent slitting process, the top of the side wall of the base 31 in this embodiment is set as an inclined surface, and this inclined surface facilitates the sliding of the lead frame.

[0020] In order to facilitate the collection and packaging of the terminals, both ends of the slitting groove 3 in this embodiment are provided with openings, and a rectangular frame 32 is provided at one end of the slitting groove 3. When in use, insert the open end of the packaging strip into the rectangular frame 32, and then push the terminals in the slitting groove 3 into the packaging strip with the help of tools such as a push rod.

[0021] Specifically, asFigure 2 As shown, the slitting mechanism 2 includes a cutter 21 and four guide rods 22. The four guide rods 22 can be directly arranged on the top of the cutter 21. In order to make room for the power mechanism 1, in this embodiment, two flat plates 213 are arranged on each side of the cutter 21, and the guide rods 22 are arranged on the tops of the corresponding flat plates 213. The guide rods 22 penetrate upward through the support 23, and the support 23 is fixedly arranged on the base 31. A spring 24 is arranged on the outer periphery of the guide rod 22, and the two ends of the spring 24 are respectively connected to the support 23 and the cutter 21. A round plate 221 with a diameter larger than its own is arranged at the top of the guide rod 22 to prevent the cutter 21 from accidentally falling. The cutter 21 is located above the slitting groove 3 and is used to cut the lead frame when it moves downward.

[0022] Specifically, the power mechanism 1 is arranged on the support 23 and is used to control the up and down movement of the cutter 21. The specific implementation method of the power mechanism 1 in this embodiment is as follows:

[0023] As Figures 2 - 4 shown, the power mechanism 1 includes a motor 11, a rotating shaft 12 and two driving blocks 13. The end of the rotating shaft 12 is rotatably connected to the support 23, and the output shaft of the motor 11 is used to drive the rotating shaft 12. Two bases 211 are sequentially arranged on the top of the cutter 21 along its long axis direction, and rollers 212 are rotatably arranged on the bases 211. The two driving blocks 13 are sequentially arranged on the rotating shaft 12, and the side surface of the driving block 13 is closely attached to the side surface of the corresponding roller 212. As Figure 4 shown, the driving block 13 is a symmetric structure. In the clockwise direction, the side surface of the driving block 13 sequentially includes a first arc surface, a first plane, a second arc surface, and a second plane. The centers of the first arc surface and the second arc surface are located on the axis of the rotating shaft 12, and the radius of the first arc surface is smaller than the radius of the second arc surface.

[0024] When the first arc surface is closely attached to the side surface of the roller 212, the cutter 21 is located above the slitting groove 3; when the second arc surface is closely attached to the side surface of the roller 212, it is used to make the cutter 21 cut the lead frame.

[0025] The usage method is as follows: Place as Figure 1The connecting body of the terminal and the lead frame shown is placed in the slitting groove 3, where the terminal is located in the slitting groove 3, and the lead frame connected to the terminal is supported on the top of the side wall of the slitting groove 3; the motor 11 drives the rotating shaft 12, and the driving block 13 rotates accordingly. When the second arc surface of the driving block 13 gradually approaches and closely adheres to the side surface of the roller 212, the cutter 21 is urged to move downward to cut the lead frame; the motor 11 continues to drive the rotating shaft 12, and the second arc surface of the driving block 13 gradually moves away from the side surface of the roller 212, while the first arc surface of the driving block 13 gradually approaches and closely adheres to the side surface of the roller 212, and the cutter 21 moves upward and returns to its original position; after slitting, the terminal remains in the slitting groove 3, and the lead frame falls outside the slitting groove 3 and slides down along the inclined surface of the side wall of the base 31; the open end of the packaging strip is inserted into the rectangular frame 32, and then the terminal in the slitting groove 3 is pushed into the packaging strip by means of tools such as a push rod, thus completing the collection and packaging of the terminal.
