Description

Technical Field

[0001] This utility model belongs to the field of cutting machine technology, and in particular relates to a cutting machine for a computer carrier board. Background Technology

[0002] With the rapid development of the electronic information industry, the demand for printed circuit boards (PCBs), as the core carrier of electronic devices, has exploded. PCBs play a crucial role in smartphones, computers, and IoT devices. Their dimensional accuracy and edge quality directly determine the integration level of electronic components, signal transmission efficiency, and overall product reliability. In the production process, the cutting machine, as an essential piece of equipment for dividing large-size copper-clad laminates into standard small pieces, is crucial to the yield rate and production cost of the PCB.

[0003] However, existing cutting machines are not convenient for positioning the carrier plate during use, making it difficult to ensure that the carrier plate is always perpendicular to the cutting line, which leads to deviations in cutting size and position, affecting the subsequent processing quality. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting machine for computer carrier boards. By setting a central positioning part, it solves the problem that existing cutting machines are not convenient for positioning the carrier board during use, and it is difficult to ensure that the carrier board is always perpendicular to the cutting line, which leads to deviations in cutting size and position and affects the subsequent processing quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a cutting machine for a computer carrier board, comprising a base plate and two support platforms mounted on the top of the base plate, and further comprising: a support part disposed on the top of the base plate; two centering positioning parts disposed on the two support platforms respectively; a cutting part disposed on the base plate; each centering positioning part includes a power component disposed on a corresponding support platform; and a positioning component disposed on a corresponding support platform; the power component includes a rectangular groove formed on the right support platform, a slider slidably connected to the inner wall of the rectangular groove, two hinge rods hinged to the slider, each hinge rod having a hinge shaft passing through it, and a power component disposed within the rectangular groove; the two hinge shafts are rotatably connected to the two hinge rods respectively, and the power component includes a hydraulic cylinder fixedly connected to the inner wall of the top of the rectangular groove; the output shaft of the hydraulic cylinder is fixedly connected to the slider.

[0007] Furthermore, the positioning component includes annular blocks respectively hinged on two hinge axes, each annular block having two guide pins passing through it, and a positioning block fixedly connected to the side of the two annular blocks that is close to each other; a plurality of guide pins are fixedly connected to the right support platform on the side that is close to the right support platform.

[0008] Furthermore, the support includes workbenches fixedly connected to the tops of the two support platforms respectively, and a support member is provided above the base plate; the two workbenches are mirror images of each other, and the support member includes a support rod fixedly connected between two rectangular rods; the top of the support rod is flush with the top of the two workbenches.

[0009] Furthermore, the cutting section includes a pressing assembly mounted on the top of the base plate; and a cutting assembly positioned above the base plate. The pressing assembly includes two rectangular rods fixedly connected to the top of the base plate, a rectangular box fixedly connected between the two rectangular rods, a second hydraulic cylinder fixedly connected to the top inner wall of the rectangular box, and a rectangular pressure plate fixedly connected to the output shaft of the second hydraulic cylinder. The outer wall of the rectangular pressure plate is slidably connected to the inner wall of the rectangular box, and the bottom of the rectangular pressure plate extends outside the rectangular box.

[0010] Furthermore, the cutting assembly includes a mounting groove formed at the bottom of a rectangular pressure plate. A motor is fixedly connected to the right side of the rectangular pressure plate. The output shaft of the motor is fixedly connected to a threaded rod via a coupling. The threaded rod extends rotatably into the mounting groove, and a cutting element is provided on the threaded rod. The motor is located below the rectangular box. The cutting element includes a mounting block threadedly connected to the outer wall of the threaded rod, and a cutting module is mounted on the mounting block. The outer wall of the mounting block is slidably connected to the inner wall of the mounting groove.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting a central positioning part, during positioning, its power component uses a hydraulic cylinder as the power source to drive the slider to slide in the rectangular groove, and then drives the positioning component to move through the transmission of the hinge rod and hinge shaft; the positioning component uses the directional movement of the ring block on the guide pin to bring the two positioning blocks closer to each other and clamp the computer carrier board placed on the worktable in a centered manner. This design can effectively reduce the positional deviation when the carrier board is placed and ensure that the carrier board is always perpendicular to the cutting line, thereby avoiding problems such as deviation in cutting size and position and irregular edges caused by carrier board offset.

[0013] 2. By setting up a cutting section, during cutting, a rectangular pressure plate is driven up and down by a hydraulic cylinder. Before cutting, the plate is firmly pressed onto the worktable and support rod, preventing the plate from being affected by vibration or displacement during the cutting process, thus ensuring the safety of the cutting operation. The cutting assembly is powered by a motor, which drives the threaded rod to rotate, causing the mounting block to slide in the mounting groove, thereby driving the cutting module to move. Combined with the pressing action of the lowering assembly, stable cutting of the plate is achieved. This structure, through reasonable power transmission and structural design, realizes automatic cutting of the plate, avoiding intermittent stops in manual operation, reducing manual training costs and the probability of human error, and ensuring the safety and continuity of the production process.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
