Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to a slitting device for circuit board processing. Background Technology

[0002] A circuit board is an important electronic component that provides electrical connections and physical support for electronic elements. Its basic structure mainly consists of an insulating substrate, copper foil traces, and various holes, forming the foundation of the circuit board and serving both support and insulation functions. A commonly used insulating substrate material is FR-4, which possesses good mechanical strength, insulation properties, and chemical stability. In some specialized applications, vias are used for mounting electronic components (including through-holes) and establishing electrical connections between different layers. The size of through-holes depends on the size of the component leads, while vias typically have smaller diameters and are mainly used to connect different layers of the circuit board, such as the connection between the inner and outer layers of a multilayer circuit board.

[0003] In some existing circuit board processing slitting devices, when slitting circuit boards, the circuit board is placed on a worktable, clamped and fixed by clamping plates and bars, and then the cutting tool is driven by the cutting motor to rotate at high speed to cut the circuit board.

[0004] Existing slitting devices for circuit board processing have the following problems: the circuit boards are not securely fixed during slitting, and they are prone to shifting, which reduces the slitting quality. To address this, we propose a slitting device for circuit board processing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a slitting device for circuit board processing. When slitting the circuit board, the left and right ends and the upper edge of the circuit board are fixed, which improves the fixing effect and makes it less likely to shift, thereby improving the slitting quality of the circuit board and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a slitting device for circuit board processing, comprising a machine base, a robotic arm provided on the upper rear side of the machine base, a laser cutting head provided on the upper front side of the robotic arm, and a clamping mechanism;

[0007] Clamping mechanism: It includes guide posts, sliding plates, support rods, top bars, connecting rods, linking rods, and pressure bars. Symmetrical guide posts are fixedly connected between the left and right inner walls of the machine base. Sliding plates are slidably connected to the left and right ends of the two guide posts. Support rods are fixedly connected to the upper ends of the sliding plates. Top bars are fixedly connected to the upper ends of the support rods. Connecting rods are rotatably connected to the upper sides of the support rods. Linking rods are fixedly sleeved on the outer sides of the left and right sides of the connecting rods. Pressure bars are fixedly connected between the inner ends of two longitudinally adjacent linking rods. When cutting the circuit board, the left and right ends and the upper edge of the circuit board are fixed, resulting in better fixation, less likelihood of displacement, and improved cutting quality.

[0008] Furthermore, a microcontroller is installed on the outside of the machine tool. The input terminal of the microcontroller is electrically connected to an external power source, and the input terminals of the robotic arm and the laser cutting head are both electrically connected to the output terminal of the microcontroller, providing electrical connections for all electrical components.

[0009] Furthermore, the clamping mechanism also includes a vertical plate, a C-shaped rod, and a sliding groove. The upper end of the sliding plate is provided with symmetrical vertical plates. A C-shaped rod is rotatably connected between two longitudinally adjacent vertical plates. A sliding groove is opened at the lower end of the connecting rod. The outer surface of the inner end of the C-shaped rod is slidably connected to the inner surface of the vertically adjacent sliding groove, providing a rotatable connection.

[0010] Furthermore, the clamping mechanism also includes gear one, gear two, and motor two. Gear one is fixedly sleeved in the middle part of the C-shaped rod, and motor two is respectively provided at the upper end of the sliding plate. Gear two is fixedly connected to the rear end of the output shaft of motor two. Gear one meshes with the adjacent gear two in the lateral direction. The input end of motor two is electrically connected to the output end of the microcontroller to provide rotation drive.

[0011] Furthermore, the clamping mechanism also includes a bidirectional lead screw, which is rotatably connected to the middle between the left and right inner walls of the machine base. The left and right ends of the bidirectional lead screw are respectively threaded to the threaded holes in the middle of the vertically adjacent sliding plates, providing a rotatable connection.

[0012] Furthermore, the clamping mechanism also includes a motor, which is located at the left end of the machine base. The right end of the output shaft of the motor is fixedly connected to the left end of the bidirectional lead screw. The input end of the motor is electrically connected to the output end of the microcontroller to provide movement drive.

[0013] Furthermore, the lower end of the machine tool is provided with support legs.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This circuit board processing slitting device has the following advantages:

[0015] Driven by motor one, the support rod and the top bar clamp the two ends of the circuit board through the double-acting screw and the sliding plate of the threaded plate. Then, driven by motor two, the C-shaped rod rotates through gear two and meshing gear one. The two ends of the C-shaped rod slide and rotate inside the groove, which in turn drives the middle part of the connecting rod at both ends to rotate downward with the connecting rod as the rotation point. This drives the pressure bar to clamp the upper end of the circuit board. When cutting the circuit board, the left and right ends and the upper edge of the circuit board are fixed, which has a better fixing effect and is less likely to shift, thus improving the cutting quality of the circuit board.

The sliding plate 504 comprises a plate 510, a C-shaped rod 511, and a sliding groove 512. The upper end of the sliding plate 504 is provided with symmetrical vertical plates 510. Two longitudinally adjacent vertical plates 510 are rotatably connected by C-shaped rods 511. The lower end of the connecting rod 508 is provided with a sliding groove 512. The outer surface of the inner end of the C-shaped rod 511 is slidably connected to the inner surface of the vertically adjacent sliding groove 512. The clamping mechanism 5 also includes a first gear 513, a second gear 514, and a second motor 515. The middle part of the C-shaped rod 511 is fixedly fitted with a first gear 513.

Then, by controlling the microcontroller 6, motor 501 operates, and the output shaft of motor 501 drives the bidirectional lead screw. Rotation of screw 502 causes the threaded sliding plate 504 to move towards each other between guide posts 503, which in turn causes the top bar 506 to move towards each other via support rod 505, clamping both ends of the circuit board.

Then, by controlling the microcontroller 6, motor 1 501 operates. The output shaft of motor 1 501 drives the bidirectional lead screw 502 to rotate. The rotation of the bidirectional lead screw 502 drives the threaded sliding plate 504 to move towards each other between the guide posts 503, which in turn drives the top bar 506 to move towards each other through the support rod 505 to clamp the two ends of the circuit board. Then, by controlling the microcontroller 6, motor 2 515 operates. The output shaft of motor 2 515 will drive gear 2 514 to rotate.

The two ends of C-shaped rod 511 slide and rotate inside the slide groove 512, which will drive the middle part of the connecting rod 508 at both ends to rotate downward with the connecting rod 507 as the rotation point. This will drive the pressure bar 509 to clamp the upper end of the circuit board. Then, through the control of the microcontroller 6, the robotic arm 3 and the laser cutting head 4 will operate to cut the circuit board.
