Description

Technical Field

[0001] The present invention relates to the field of circuit boards, and particularly to a circuit board pin cutting device. Background Art

[0002] In the field of electronic device manufacturing, circuit boards are key components for connecting and transmitting electronic signals. Traditional circuit boards are usually composed of multiple-layer printed circuit boards (PCBs), and pins for connecting other electronic components are installed at the bottom. The accuracy and consistency of these pins are crucial for the performance of the circuit board.

[0003] In the prior art, pin cutting methods usually rely on manual operation or simple mechanical cutting, resulting in inconsistent pin lengths and affecting the connection quality of the circuit board. At the same time, due to the accuracy limitations of the cutting equipment, the cutting surface of the pins is often not smooth enough, prone to burrs, and affecting the electrical performance of the circuit board. Utility Model Content

[0004] Aiming at the deficiencies in the prior art, the present invention provides a circuit board pin cutting device. The pin cutting device has a simple structure and can neatly cut the pins under the components of the circuit board through a cutting disc, so that the pin lengths on the circuit board are kept consistent.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A circuit board pin cutting device, comprising:

[0006] A frame;

[0007] A cutting assembly, the cutting assembly includes a cutting chamber, a cutting motor is fixed in the cutting chamber, and a cutting disc is fixed on the cutting motor;

[0008] A feeding assembly, the feeding assembly includes a feeding chute, the feeding chute is fixed in the frame and is located above the cutting disc. A feeding slideway is slidably connected in the feeding chute, and a clamping portion is provided at the bottom of the feeding slideway;

[0009] A limiting and pushing assembly, the limiting and pushing assembly is fixed at the end of the feeding slideway and includes a limiting frame and a pushing head.

[0010] Further, a support frame is fixed above the cutting disc on the frame, and the feeding assembly is fixed on the support frame.

[0011] Further, the limiting and pushing assembly further includes a mounting block, the limiting frame is fixed on the upper part of the mounting block, a pushing head is fixed on the side of the mounting block, and a control handle is further fixed on the top of the mounting block.

[0012] Further, auxiliary chutes are provided on both sides of the frame, and an auxiliary slideway is also fixed at the end of the feeding slideway. The auxiliary slideway is slidably connected to the auxiliary chute.

[0013] Further, a blanking support is provided at the end of the frame, and a blanking guide plate is fixed on the blanking support.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, by integrating the cutting component and the feeding component on a frame, the device occupies a small space, is convenient for installation and use. The fixed design of the cutting motor and the cutting disc ensures the stability during the cutting process, thereby improving the accuracy and consistency of the pin cutting.

[0016] Second, the design of the pushing head and the operating handle of the limiting and pushing component enables the operator to more flexibly control the pushing process, improving the flexibility and accuracy of the operation. In addition, due to the setting of the limiting frame, the circuit board can be limited in the vertical direction, so that the circuit board will not move up and down when the pins of the circuit board below are being processed;

[0017] Third, the coordinated operation of the auxiliary chute and the auxiliary slideway can make the feeding component move more stably and smoothly during movement, and is not prone to deviation and jamming;

[0018] Fourth, since a high-speed rotating cutting motor is used to drive the cutting disc to rotate, the pins can be kept smooth and flat after cutting. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0024] As Figures 1-3 shown, a circuit board pin cutting device includes:

[0025] A frame 1 for connecting a cutting component and a feeding component;

[0026] A cutting component, the cutting component includes a cutting bin 2, a cutting motor is fixed in the cutting bin 2, a cutting disc 4 is fixed on the cutting motor, the cutting disc 4 is above the surface of the cutting bin, and its edge is sharp, ensuring that when cutting the pins, the pins can be flat. At the same time, since the cutting disc always rotates in the same plane, all the pins it cuts can maintain the same length;

[0027] A feeding component, the feeding component includes a feeding chute 5, the feeding chute 5 is fixed in the frame 1 and is located above the cutting disc 4. A feeding slideway 6 is slidably connected in the feeding chute 5. The bottom of the feeding slideway 6 has a clamping portion 7. Through the setting of the clamping portion 7, the circuit board can be clamped above this clamping portion;

[0028] A limiting and pushing component, the limiting and pushing component is fixed at the end of the feeding slideway 6, and it includes a limiting frame 8 and a pushing head 9. After the circuit board is clamped on the clamping portion, the circuit board is pushed to the right so that the circuit board contacts the pushing head. At the same time, the vertical movement of the circuit board is restricted by the limiting frame. When the circuit board needs to move, the pushing head is directly moved to the left.

[0029] The process of using the present utility model is as follows. First, place the circuit board whose pins need to be cut on the feeding component. Specifically, it is limited above the clamping portion 7 at the bottom of the feeding slideway 6. After the circuit board is positioned, it is pushed forward by the limiting and pushing component. During the process of pushing the circuit board forward, the cutting disc 4 can cut the pins at the bottom of the circuit board. Finally, take out the cut circuit board.

[0030] Further, a support frame 10 is fixed above the cutting disc 4 on the frame 1, and the feeding component is fixed on the support frame 10. Specifically, the feeding component of the present utility model is fixed on the support frame 10, and its installation is more rapid and convenient.

[0031] Further, the limiting and pushing component further includes a mounting block 11. The limiting frame is fixed on the upper part of the mounting block 11. A pushing head 9 is fixed on the side of the mounting block 11. A control handle 13 is also fixed on the top of the mounting block 11. Specifically, the pushing head 9 and the limiting frame 8 of the limiting and pushing component of the present utility model are both fixed on the mounting block 11, and the mounting block 11 is controlled by the control handle 13.

[0032] Further, auxiliary chutes 14 are also provided on both sides of the frame 1. An auxiliary slideway 15 is further fixed at the end of the feeding slideway 6. The auxiliary slideway 15 is slidably connected in the auxiliary chute 14. In order to make the feeding assembly slide more smoothly and stably, auxiliary chutes 14 are also provided on both sides of the frame 1, and the auxiliary slideway 15 is slidably connected in the auxiliary chute 14.

[0033] Further, a blanking support 12 is provided at the end of the frame 1. A blanking guide plate 3 is fixed on the blanking support 12. The blanking support 12 is fixed at the end of the frame 1. The blanking guide plate 3 on the blanking support 12 can guide the cut circuit board. That is, after the circuit board processing is completed, the operator manually pushes it to the left to make it fall onto the blanking guide plate 3 for sliding. When it slides downward, it can move along the direction of the guide plate.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
