[0006] To achieve the above object, the application is implemented by the following technical scheme: a cutting device for double-sided PCBs is used for quickly clamping a PCB and comprises a clamping device: a square column, which is used for bearing a device for cutting the PCB; a cutting machine, which is used for cutting the PCB; A fixing plate, the fixing plate being fixedly mounted on the front face of the square column, a through slot being formed on the top of the fixing plate, the free end of the elastic telescopic rod being fixedly mounted on the front face of the fixing plate, one end of the short plate being fixedly mounted on the free end of the elastic telescopic rod, and the rubber block being fixedly mounted on the bottom of the other end of the short plate, the rubber block being used to clamp the PCB and prevent damage to the PCB; An elongated plate, the elongated plate being fixedly mounted on the top of the fixed plate, the convex block being fixedly mounted on a side of the elongated plate close to the cutting machine, the convex block being used to generate vibration to reduce the possibility that the cut PCB board is stuck in the through-slot of the fixed plate; A long diagonal rod is fixedly installed on the front side of the square column, and the position plate is slidably installed on the surface of the long diagonal rod. The position plate is used to push the PCB board residue between the fixed plate and the square column to prevent the residue from being stuck. When the PCB board is placed, the staff will take both hands off the top of the fixed plate. At the same time, the staff needs to use both hands to pull the card rod and step on the free end of the telescopic plate. When the free end of the telescopic plate is stepped on, it will move toward the fixed end.

[0007] According to the above technical solution, the clamping device also includes a telescopic plate, a long column, a connecting column, a long plate, a pulley plate, a sliding card plate, a trapezoidal block and a top plate, the fixed end of the telescopic plate is fixedly installed on the front bottom of the square column, one end of the long column is fixedly installed on the free end of the telescopic plate, the connecting column is fixedly installed on the other end of the long column, the top plate is fixedly installed on the front of the square column, the sliding card plate is slidably installed on the top of the top plate, one end of the long plate is fixedly installed on the left side of the telescopic plate, the trapezoidal block is fixedly installed on the top of the sliding card plate, the pulley plate is fixedly installed on the other end of the long plate, and the pulley plate is used to push the trapezoidal block outward, and when the trapezoidal block moves, it will drive the sliding card plate to move, and when the sliding card plate moves, the limit on the protective plate will be released, and when the limit of the protective plate is released, the protective plate will flip down.

[0008] According to the above technical solution, the clamping device also includes an elastic telescopic column, a clamping rod, a baffle plate and a protective plate.

At the same time, a No. 2 spring is set on the side of the baffle plate close to the square column, so that the protection plate can be prevented from being directly flipped over and causing damage.

[0009] According to the above technical solution, the separation device includes an elastic telescopic plate, a rotating plate, a protrusion and a supporting rod. The elastic telescopic plate is fixedly installed on the top of the fixed plate close to the side of the elastic telescopic rod, the supporting rod is fixedly installed on the front of the cutting machine, the protrusion is fixedly installed on the bottom of the supporting rod, and the rotating plate is rotatably installed on the bottom of the supporting rod. When the rotating plate moves, it will contact the elastic telescopic plate. Since the supporting rod is rotatably connected to the top of the rotating plate close to the cutting machine, when the rotating plate contacts the elastic telescopic plate during the forward movement, the rotating plate will be flipped.

[0010] According to the above technical solution, the elastic telescopic plate contacts the convex block, the elastic telescopic plate contacts the rotating plate, and the convex block contacts the long oblique rod.

The cover plate is slidably installed on the left side of the fixed plate, the telescopic rotating plate is rotatably installed on the left side of the fixed plate, the elastic telescopic inclined plate is fixedly installed on the left side of the fixed plate, and the box loading device is slidably installed on the left side of the square column. When the box loading device moves downward, it will drive the elastic telescopic inclined plate to be squeezed. When the elastic telescopic inclined plate is squeezed, it will first move away from the direction of the box loading device. When the elastic telescopic inclined plate moves, it will drive the telescopic rotating plate to rotate.

[0012] According to the above technical solution, the collection device also includes an L-plate and an elastically retractable rectangular plate. The L-plate is slidably installed on the left side of the square column, one end of the elastically retractable rectangular plate is fixedly installed on the back of the cutting machine, and the position plate is fixedly connected to the other end of the elastically retractable rectangular plate. When the box is moved, the L-plate will be squeezed to move, and when the L-plate is squeezed, it moves downward.

[0013] According to the above technical solution, a No. 1 spring is provided between the L-plate and the square column, the free end of the telescopic rotating plate is rotatably connected to the free end of the elastic telescopic inclined plate, the cover plate is rotatably connected to the free end of the telescopic rotating plate, and a No. 3 spring is provided between the elastic telescopic rectangular plate and the fixed plate. When the L-plate moves, the elastic force of the No. 1 spring will cause the L-plate to return to its original position when the limit is released.

[0014] The present invention provides a double-sided PCB cutting device. It has the following beneficial effects: (1) In this invention, when the elastic telescopic rod moves, it drives the short plate to move, and when the short plate moves, it drives the rubber block to move. When the rubber block moves, it quickly clamps the PCB board and can prevent the PCB board from being damaged by a large clamping force. After the staff has placed the PCB board, they need to use both hands to pull the clamping rod outward, which can effectively prevent the staff from operating improperly and causing work injuries. When the sliding clamping plate moves, the limit on the protective plate at the bottom of the top plate is released. When the limit of the protective plate is released, it protects the staff and prevents small items inside the PCB board from flying out when cutting and affecting the staff's eyes.

[0015] (2) In this invention, when the rotating plate moves, it drives the elastic telescopic plate to move, and when the elastic telescopic plate moves, it pushes the items on the fixed plate, and the finished products are discharged from the through holes on the fixed plate, which can realize the separation of the finished products and the residual materials. When the elastic telescopic plate moves, it contacts the convex blocks on the long plate, and when the convex blocks contact the elastic telescopic plate, vibration is generated, which shakes off the finished products that may remain in the through holes of the fixed plate, thereby preventing the finished products stuck inside the fixed plate from lifting the PCB board above and affecting the subsequent cutting.

[0016] (3) In this invention, when the elastically retractable rectangular plate moves, it will drive the position plate to move as well. When the position plate moves, it will align the residual materials between the fixed plate and the square column, facilitating subsequent sorting operations. When the box is moved downward, it will drive the L plate to move downward. When the L plate moves downward, the limit on the box is released. When the limit on the box is released, it can effectively save the time for replacing the box, and can also avoid the difficulty in sorting and removing when too many boxes are piled up, and avoid the inability to effectively collect the remaining residual materials when the staff is sorting the residual materials.
