Description

Technical Field

[0001] The utility model relates to the technical field of circuit board segmentation, in particular to a circuit board segmentation device. Background Art

[0002] Traditionally, a roller cutter is used to cut a circuit board. After the staff takes the circuit board from the assembly line, they cut it on the roller cutter. Since the circuit board is generally a quadrilateral, the staff needs to place the circuit board on the roller cutter for four times. If the staff operates improperly or is not focused, there is a risk of cutting, and manual operation without fixing it can easily lead to inaccurate cutting accuracy.

[0003] An existing circuit board cutting machine includes a base plate, an upper fixed shaft is arranged above the base plate, a plurality of upper cutting knives are arranged on the upper fixed shaft, a lower fixed shaft is also arranged between the upper fixed shaft and the base plate, lower cutting knives are arranged on the lower fixed shaft at positions corresponding to the upper cutting knives, a plurality of positioning rods rotatably connected to the upper fixed shaft are also arranged on the upper fixed shaft, a positioning wheel rotatably connected to the positioning rod is arranged at the end of the positioning rod, a torsion spring is arranged between the positioning rod and the upper fixed shaft, a support plate is also arranged between the positioning rod and the base plate, a plurality of ball bearings are arranged on the upper end surface of the support plate, the support plate is fixed to the base plate through a supporting device, a plurality of sliding rods are fixed above the base plate on both sides of the support plate, a fixed seat is also arranged above the base plate on both sides of the support plate, and the two fixed seats are driven to move by a motor.

[0004] However, the splitting machine controls the movement of the circuit board and cuts the side of the circuit board through the upper and lower cutters. If the circuit board is set to a rectangle, the front and back sides of the circuit board cannot be cut at the same time. If the front and back sides of the circuit board are to be cut, they need to be cut again, which wastes the cutting time of the circuit board. Utility Model Content

[0005] The utility model aims to provide a circuit board dividing device which can divide the side edge and the bottom edge of the circuit board simultaneously.

[0006] In order to achieve the above-mentioned purpose, the circuit board dividing device provided by the utility model comprises a base plate, a positioning plate is arranged above the base plate, a support rod is fixed on the positioning plate, and a lever arm is movably connected to the support rod; a mounting plate is also arranged on the base plate, a guide arm is movably connected to the mounting plate, the guide arm is provided with a first slide groove, and the guide arm is connected with the lever arm; a connecting hole is arranged on the top of the positioning plate, a guide block is arranged above the positioning plate, a connecting shaft is arranged below the guide block, the connecting shaft passes through the connecting hole, an elastic component is sleeved outside the connecting shaft, a first end of the elastic component abuts against the guide block, and a second end of the elastic component abuts against the positioning plate; a second slide groove is arranged on the guide block, the first slide groove is connected to the second slide groove, and an end of the first slide groove close to the second slide groove is arranged at the same height as the second slide groove; a pressing mechanism is arranged below the support rod, and the pressing mechanism is fixed above the guide block; the positioning plate is also provided with a cutting knife, and the blade end of the cutting knife is adjacent to the guide block.

[0007] It can be seen from the above scheme that when the circuit board needs to be cut, the circuit board is placed between the first slide slot and the second slide slot, and the staff can move the guide arm downward so that the circuit board is broken between the first slide slot and the second slide slot. At this time, the circuit board cutting device cuts the bottom edge of the circuit board. Since a pressing mechanism is provided under the lever arm, when the staff moves the guide arm, the lever arm is simultaneously driven to move toward the pressing mechanism. At this time, the lever arm can apply pressure to the pressing mechanism, the guide block moves downward, the elastic component is compressed, and the guide block drives the circuit board to move downward, and the cutter can cut the side of the circuit board. The staff can move the guide arm downward once to cut the bottom edge and the side edge of the circuit board, thereby improving the work efficiency of circuit board cutting.

[0008] In a further solution, a limiting mechanism is further connected to the bottom plate, and a third sliding groove is arranged on the limiting mechanism, and the third sliding groove and the second sliding groove are arranged at the same height.

[0009] It can be seen that the limiting mechanism can limit the position of the circuit board, so that the circuit board can be accurately positioned during cutting.

[0010] In a further solution, a guide arm is provided on a first side of the guide block, and a limit mechanism is provided on a second side of the guide block.

[0011] It can be seen that the height of the circuit board is determined by setting the limiting mechanism and the guide arm.

[0012] In a further solution, a collecting mechanism is provided on the second side of the limiting mechanism.

[0013] It can be seen that the collecting mechanism can collect the residual materials after the circuit board is cut on the guide block.

[0014] In a further solution, the first end of the lever arm is movably connected to the support rod, and the second end of the lever arm is connected to the first end of the adjusting column; the second end of the adjusting column is connected to the first end of the guide arm, and the second end of the guide arm is movably connected to the mounting plate.

[0015] It can be seen that by adjusting the column, the distance between the lever arm and the support rod can be adjusted, thereby adjusting the height of the lever arm and the guide block when pressing.

[0016] In a further solution, the pressing mechanism includes a support frame, a first end of the support frame is fixed to the guide block, a second end of the support frame is provided with a mounting hole, and the adjustment mechanism is provided on the mounting hole.

[0017] In a further solution, the adjustment mechanism includes a first screw, a first nut and a second nut, the first screw passes through the mounting hole, the first nut and the second nut pass through the first screw, and the first nut and the second nut are arranged at both ends of the mounting hole.

[0018] It can be seen that the height of the pressing mechanism and the lever arm can be adjusted through the adjusting mechanism, thereby adjusting the height of the worker when splitting the circuit board.

[0019] In a further solution, a limit plate is arranged above the guide block, and the limit plate is fixed to the mounting plate.

[0020] It can be seen that the limiting plate can limit the upward movement of the guide block and the upward movement of the guide arm.

[0021] In a further solution, two support rods are provided, and the connecting rod passes through the two support rods; two lever arms are provided, and one lever arm is movably connected to one support rod through the connecting rod.

[0022] It can be seen that the connecting rod can connect the two support rods and is a movable connection of the lever arm.

[0023] In a further solution, the mounting plate and the guide arm are provided in two, one mounting plate is movably connected to one guide arm, and a pressing arm is provided between the two guide arms.

[0024] It can be seen that providing the pressing arm facilitates operation by the staff. BRIEF DESCRIPTION OF THE DRAWINGS
