Description

Technical Field

[0001] This invention relates to the field of circuit board manufacturing, and more particularly to a circuit board slitting device. Background Technology

[0002] In order to improve the production efficiency of circuit boards, multiple circuit boards are often made from a single circuit board during the production process. This method can significantly improve the production efficiency of circuit boards. After production is completed, the circuit boards are usually slit by a slitting device.

[0003] Patent application number CN202323489178.0 discloses a circuit board slitting device, including a placement platform and a limiting device. A placement block is fixedly connected to the upper surface of the placement platform, and a mold is provided on the inner wall of the placement block. A connecting arm is fixedly connected to the side of the placement platform, and a cutter is provided on the surface of the connecting arm. The limiting device is located on the surface of the mold and includes a limiting rod and a groove. The groove is formed on the surface of the mold, and the limiting rod is fixedly connected to the inner wall of the mold. A slot is formed on the inner wall of the groove. When using the device, the user places the material to be cut inside the mold and then starts the cutter to cut the material. However, this type of slitting device requires removing the slitting circuit board and repositioning it after slitting before the next slitting operation can be performed, severely affecting the production efficiency of the circuit boards.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a circuit board slitting device.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a circuit board slitting device, comprising a table, on which positioning devices are symmetrically fixed on both sides. Each positioning device includes multiple positioning blocks. A vertical plate is also fixed on one side of the table. A lead screw and a sliding rod are provided on the vertical plate. The lead screw is driven to rotate by a positioning motor. A sliding plate threadedly connected to the lead screw is provided on the lead screw. The sliding rod passes through the sliding plate and is slidably connected to the sliding plate. A rotary motor is also fixed on the sliding plate. A rotating shaft is fixed to the output end of the rotary motor. A fixing plate is fixed to the end of the rotating shaft. Multiple lifting cylinders are evenly fixed on the fixing plate. An mounting plate is also provided below the fixing plate. The piston rod ends of the lifting cylinders are fixed to the mounting plate. A cutting shaft is provided on the mounting plate. Multiple cutting wheels are evenly fixed on the cutting shaft. The circuit board to be cut is placed in the positioning device position. After the circuit board is fixed by the positioning block, the lifting cylinder is activated, the piston rod of the lifting cylinder extends, the cutting wheel descends, and the cutting motor drives the cutting shaft to rotate. The cutting wheel rotates at high speed with the cutting shaft, and the positioning motor drives the lead screw to rotate. When the lead screw rotates, the slide moves in the direction of the lead screw, and the cutting wheel moves towards the circuit board. After the cutting wheel contacts the circuit board, it cuts the circuit board. After the cutting wheel moves from one side of the circuit board to the other side, it cuts the circuit board into multiple pieces. After the circuit board is cut, the lifting cylinder is activated, the piston rod of the lifting cylinder shortens, the cutting wheel rises, the rotary motor drives the rotary shaft to rotate 180 degrees, the fixing plate rotates 180 degrees around the rotary shaft, and the cutting wheel rotates 180 degrees with the fixing plate around the rotary shaft. At 0 degrees, the lifting cylinder restarts, the cutting wheel descends again, and reaches the side of another positioning device. The positioning motor drives the lead screw to rotate in the opposite direction, and the cutting wheel moves towards the circuit board at the other positioning device position, cutting the other circuit board. This device can cut circuit boards, and positioning devices are set on both sides of the table. When the cutting wheel cuts one circuit board, the circuit board can be placed at the other positioning device position. After the circuit board is cut, it is rotated 180 degrees to cut another circuit board. The cut circuit board is removed, and the circuit board to be cut is placed again. This device can continuously cut circuit boards without waiting to remove and place the circuit board, which greatly improves the cutting efficiency of circuit boards.

[0008] Preferably, the positioning device further includes a support plate fixed to the table surface, with positioning blocks evenly distributed around the periphery of the support plate, and blade grooves provided at the upper end of the support plate corresponding to the cutting wheel. When the circuit board is placed on the support plate, the bottom of the cutting wheel moves within the blade grooves during circuit board cutting, thereby completely cutting the circuit board.

[0009] Preferably, the positioning block passes through the tabletop and is slidably connected to it. Positioning plates are provided below each of the positioning device locations on the tabletop, and each positioning block is fixed to a corresponding positioning plate. Multiple positioning cylinders are also fixed to the lower end of the tabletop, and the piston rods of these cylinders are fixed to corresponding positioning plates. After the circuit board is cut, the positioning cylinders are activated, the piston rods of the positioning cylinders extend, and the positioning block reaches below the tabletop, facilitating the removal of the cut circuit board.

[0010] Preferably, a material receiving device is fixed on one side of the platform of the positioning device. The material receiving device includes a pushing cylinder fixed on the platform, and a push plate is fixed to the end of the piston rod of the pushing cylinder. A support rod is also fixed on the platform, and the support rod passes through the push plate and is slidably connected to the push plate. After the positioning block reaches below the platform, the pushing cylinder is activated, the piston rod of the pushing cylinder extends, the push plate moves, and the push plate pushes the slit circuit board to one side of the platform for collection.

[0011] Preferably, pressure rods are provided on both sides of the cutting shaft, and multiple pressure rollers are evenly arranged on the pressure rods. Support blocks are fixed on both sides of the pressure rods, and limit rods are fixed on the support blocks. The limit rods pass through the mounting plate and are slidably connected to the mounting plate. Limit blocks are fixed to the top of the limit rods, and springs are also fixed between the support blocks and the mounting plate. When the cutting rollers cut the circuit board, the pressure rollers press the circuit board down to prevent it from moving and ensure the quality of the cut circuit board.

[0012] Compared with existing technologies, the present invention has the following advantages:

[0013] This device can cut circuit boards and has positioning devices on both sides of the table. When the cutting wheel cuts one circuit board, the circuit board can be placed at the other positioning device. After the circuit board is cut, it is rotated 180 degrees to cut another circuit board. The cut circuit board is then removed and the circuit board to be cut is placed again. This device can continuously cut circuit boards without waiting to remove and place the circuit board, which greatly improves the cutting efficiency of circuit boards. Attached Figure Description

The cutting wheel 22 rotates at high speed with the cutting shaft 20, and the positioning motor 13 drives the lead screw 11 to rotate. When the lead screw 11 rotates, the slide plate 14 moves in the direction of the lead screw 11, and the cutting wheel 22 moves towards the circuit board. After the cutting wheel 22 contacts the circuit board, it cuts the circuit board. After the cutting wheel 22 moves from one side of the circuit board to the other side, it cuts the circuit board into multiple pieces.
