Description

Technical Field

[0001] This utility model relates to the field of PCB, and in particular to an automatic PCB board cutting machine. Background Technology

[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for electrical connections. Because it is manufactured using electronic printing technology, it is called a "printed" circuit board. In current PCB cutting operations, the PCB is usually fixed by manual pressing. However, manual operation makes it difficult to ensure that the pressure, angle, and position of each press are consistent. This can easily lead to instability and wobbling during cutting. If this instability continues, it will inevitably cause cutting errors, ultimately affecting the cutting quality of the PCB and potentially resulting in products that do not meet the corresponding specifications and standards. Utility Model Content

[0004] The technical implementation scheme of this utility model is as follows: an automatic PCB board cutting machine includes a base, a cutting machine, a cutting table, a motor, a first screw, a limiting rod, a clamping mechanism, and a limiting mechanism. The cutting machine is fixedly installed on the right rear side of the base. A rearwardly inclined guide surface is provided on the base located below the cutting machine. A cutting table is provided on the top of the base and is located in front of the cutting machine. A motor is fixedly connected to the left side of the base. A first screw is rotatably connected to the middle of the base. The output shaft of the motor is fixedly connected to the first screw. The bottom of the cutting table is threadedly connected to the first screw. Limiting rods are symmetrically fixedly connected to the middle of the base.

A clamping mechanism for clamping and fixing the PCB board is provided on the cutting table. A limiting mechanism for limiting the PCB cutting length adjustment is provided on the base. The limiting mechanism is located on the left side of the cutting machine.

[0005] More preferably, the clamping mechanism includes a fixed frame, a cylinder, and a pressure plate.

[0006] More preferably, the limiting mechanism includes a limiting plate, a limiting frame, a second screw, a rotating wheel, and rollers.

[0010] Compared with the prior art, the present invention has the following advantages: 1.

[0011] 2. By rotating the rotating wheel behind the limiting plate, the second screw is driven to rotate, causing the limiting frame and the roller to move in position.

The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0017] Example: An automatic PCB board cutting machine, such as Figure 1-3 As shown, the system includes a base 1, a cutting machine 2, a cutting table 3, a motor 4, a first screw 5, a limiting rod 6, a fixing frame 7, a cylinder 8, a pressure plate 9, a limiting plate 10, a limiting frame 1001, a second screw 11, a rotating wheel 12, and a guide roller 13. The cutting machine 2 is bolted to the right rear side of the base 1. A backward-sloping guide surface is provided on the base 1 below the cutting machine 2. The cutting table 3 is located on the top of the base 1, in front of the cutting machine 2. The motor 4 is bolted to the left side of the base 1. The first screw 5 is rotatably connected to the middle of the base 1. The output shaft of the motor 4 is fixedly connected to the first screw 5. The bottom of the cutting table 3 is threaded to the first screw 5. Limiting rods 6 are symmetrically fixed to the front and rear of the middle of the base 1. The first screw 5 is located between the front and rear limiting rods 6. The limiting rods 6 and the cutting table 3 are connected to each other. The bottom sliding fit is provided. A fixed frame 7 is fixedly connected to the top rear side of the cutting table 3. A cylinder 8 is fixedly connected to the top of the fixed frame 7 in a horizontal arrangement. A pressure plate 9 is fixedly connected to the telescopic rod of the cylinder 8. The pressure plate 9 is located in the middle of the fixed frame 7 and is used to fix the PCB board. A limit plate 10 is fixedly connected to the left rear side of the base 1. The limit plate 10 is located on the left side of the cutting machine 2. Sliding rods are slidably connected to the left and right sides of the front side of the limit plate 10. A limit frame 1001 is connected between the front ends of the two sliding rods. A second screw 11 is threadedly connected to the middle of the limit plate 10. The front end of the second screw 11 is rotatably connected to the rear side of the limit frame 1001. The second screw 11 is used to adjust the position of the limit frame 1001. A rotating wheel 12 is fixedly connected to the rear end of the second screw 11. Multiple rollers 13 are rotatably connected to the front side of the limit frame 1001.

[0018] like Figure 1-2 As shown, it also includes a fan 14, which is installed on the front side of the cutter 2 for removing debris.

[0019] like Figure 1-2 As shown, it also includes a collection box 15, which is fixedly connected to the right rear side of the base 1. The collection box 15 is located on the rear side of the cutting machine 2.

[0020] like Figure 1-2 As shown, it also includes a gasket 16. The bottom of the pressure plate 9 is fixedly connected to the gasket 16, which is made of a flexible, non-slip material.

[0021] When using this device, first adjust the position of the limiting frame 1001 according to the cutting size of the PCB board. By rotating the rotating wheel 12 behind the limiting plate 10, the second screw 11 is driven to rotate, thereby moving the limiting frame 1001. Adjusting the position of the limiting frame 1001 provides a suitable and stable limiting channel for the subsequent transport of the PCB board, ensuring that the PCB board can move smoothly along the defined path before entering the cutting area. Next, place the PCB board to be cut smoothly on the cutting table 3, with its front end close to the guide roller 13 of the limiting frame 1001. The guide roller 13 can reduce the frictional resistance when the PCB board moves. Force is applied, and initial positioning is achieved through rolling contact, ensuring the PCB board is accurately and stably positioned on the cutting table 3. The top cylinder 8 of the fixing frame 7 is then activated. The telescopic rod of cylinder 8 drives the pressure plate 9 to gradually move downwards until the flexible anti-slip pad 16 installed at the bottom of the pressure plate 9 makes tight contact with the upper surface of the PCB board. The flexible material prevents damage to the PCB board surface, while the anti-slip property increases the friction between the pressure plate 9 and the PCB board, allowing the PCB board to be more firmly fixed on the cutting table 3 during the cutting process, preventing displacement and further ensuring cutting stability. Subsequently, the operator starts the motor 4 and the cutting... Simultaneously, machine 2 operates, and motor 4 drives the first screw 5 to rotate. The first screw 5 drives the cutting table 3 to move to the right along the limit rod 6, moving the fixed PCB board closer to the cutting position below the cutting machine 2. When the PCB board moves to the cutting position, the cutting machine 2 automatically performs the cutting operation. At the same time, the fan 14 installed in front of the cutting machine 2 is turned on. The airflow generated by the fan 14 blows the debris generated during the cutting process to one side, preventing debris from accumulating in the cutting area and affecting the cutting operation, and avoiding debris residue on the PCB board surface from affecting its quality. After cutting, the PCB board will be removed from the cutting machine. The inclined guide surface below machine 2 slides into the collection box 15 to collect the cut PCB boards. After cutting, motor 4 is started again. Motor 4 drives the first screw 5 to rotate in the opposite direction. At the same time, the first screw 5 drives the cutting table 3 and the PCB board to reset to the left. Then, cylinder 8 is started again to retract the telescopic rod of cylinder 8, which drives the pressure plate 9 to lift up and release the fixation of the PCB board. The cut PCB board is taken out from the cutting table 3 and collected. If it is necessary to continue cutting other PCB boards, the above steps can be repeated. If it is not necessary to cut PCB boards, the cutting machine 2 can be turned off.
