[0002] Copper clad laminates are widely used in the manufacture of printed circuit boards (PCBs), and their quality and precision directly affect the performance and reliability of the circuit boards. In traditional copper clad laminate cutting technology, there are several technical problems and challenges, especially in terms of cutting accuracy and operating efficiency.

[0003] Traditional cutting equipment usually relies on simple mechanical transmission and clamping mechanisms. This method often faces problems such as sheet slippage and inaccurate cutting when dealing with large-scale or high-precision cutting operations. The slippage of copper-clad laminates during cutting is particularly prominent, mainly due to the deficiencies in the conveying and clamping mechanisms of traditional equipment. In addition, when copper-clad laminates shake or produce burrs during cutting, it not only reduces the appearance and functionality of the product, but may also cause the entire batch of products to be unqualified, thereby increasing production costs and material waste.

[0012] Furthermore, the output end of the motor is connected to a rack belt, and the first gear and the second gear are both connected to the rack belt.

[0013] Furthermore, a tensioning wheel is rotatably connected to the outer side of the mounting frame.

[0014] Furthermore, a lower pressure roller is rotatably connected to the inner side of the mounting frame, and the lower pressure roller is located above the middle of the first driving roller and the second driving roller.

[0036] See also Figure 5 The conveying assembly 2 includes a mounting frame 24 installed on the outside of the supporting frame 1, and the interior of the mounting frame 24 is symmetrically connected to the first driving roller 21 and the second driving roller 22 for rotation, and one end of the first driving roller 21 and the second driving roller 22 are respectively connected to the first gear 211 and the second gear 221; the bottom of the mounting frame 24 is provided with a motor 23 for driving the first driving roller 21 and the second driving roller 22 to rotate, and the motor 23 ensures the stability and synchronization of the copper clad laminate during the conveying process through its high-efficiency power output, thereby effectively avoiding the slippage phenomenon commonly seen in traditional cutting methods.

[0041] The working principle of the utility model is:

[0042] When in use, the copper-clad laminate to be cut is placed between the first driving roller 21 and the lower pressing roller 26. Under the drive of the motor 23 and the cooperation between the rack belt 231, the first gear 211 and the second gear 221, the first driving roller 21 and the second driving roller 22 can be made to rotate synchronously. Under the drive of the first driving roller 21 and the second driving roller 22, the copper-clad laminate to be cut is conveyed to the bottom of the pressing assembly 3. In the process of conveying, the lower pressing roller 26 located above the first driving roller 21 and the second driving roller 22 can prevent the copper-clad laminate from slipping between the first driving roller 21 and the second driving roller 22 during the conveying process.

[0043] When the copper clad laminate is conveyed to the bottom of the clamping assembly 3, the first cross bar 31 is driven downward by the first cylinder 34, and the copper clad laminate is clamped by the pressing plate 32. Then, the blade 44 is driven by the second cylinder 43 to cut the copper clad laminate. During the cutting process, the blade 44 fits the outer side surface of the pressing plate 32. In this way, the copper clad laminate will not shake during the cutting process, thereby avoiding burrs on the copper clad laminate at the cutting point, and making the cutting of the copper clad laminate more neat.
