Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, and particularly relates to a circuit board router cutter forming device. Background Art

[0002] A circuit board is a carrier for electrical connection of electronic components. To improve the production output of circuit boards, in the prior art, multiple circuit boards are usually arranged on a large substrate, and then a router cutter is used to divide the large substrate to obtain multiple smaller finished circuit boards. However, during this division process, a large amount of debris is easily generated. If it is not cleaned in time, it will have an adverse impact on the finished product quality of the circuit board.

[0003] Chinese Patent with the publication number CN220560503U discloses a rapid circuit board splitting device for a photodetector circuit board. The solution includes a base, a positioning plate, a cover plate, and a milling cutter assembly. A dust suction port is arranged at the upper end of the base, the positioning plate is arranged at the upper end of the base, the milling cutter assembly includes a milling cutter, and air jet nozzles are distributed outside the milling cutter. The above solution uses the air jet nozzles to blow up the debris generated by the milling cutter cutting, and the dust suction port on the base collects it.

[0004] When the above solution is used, it is necessary to use the air jet nozzles to blow up the debris generated by the milling cutter. The blown-up debris may still fall on the positioning plate again, and it is necessary for the air jet nozzles to work multiple times until all the debris on the positioning plate is blown out. This process takes a long time, resulting in low work efficiency and relatively wasteful energy. Content of the Utility Model

[0005] The utility model aims to provide a circuit board router cutter forming device to solve the problems of low work efficiency and relatively wasteful energy existing in the above solution.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A circuit board router cutter forming device includes a base, a fixture, and a router cutter assembly. The base has an inner cavity, an opening is arranged at the top of the inner cavity, a clamping assembly is arranged at the top of the base. The fixture includes a base and a movable seat. Both sides of the base are connected to the clamping assembly. A limiting groove is arranged at the top of the base, and multiple groups of through grooves are arranged in an array on the bottom wall of the limiting groove. The movable seat is rotatably arranged in the limiting groove, and the movable seat is also connected to the base through a locking mechanism. The router cutter assembly is located below the fixture, and the router cutter assembly includes a first motor and a router cutter. The router cutter is arranged at the top of the first motor and is in transmission connection with the first motor. The first motor is movably arranged in the inner cavity through a displacement mechanism.

[0008] The principle and effect of this technical solution:

[0009] Before forming the circuit board, release the locking mechanism and rotate the movable seat to open the limit slot, place the circuit board in the limit slot, then rotate the movable seat in the opposite direction and lock the locking mechanism so that the movable seat presses the circuit board, and the displacement mechanism drives the motor to move in the inner cavity, so that the gong cutter passes through the through slot and the circuit board, and moves along the length direction of the through slot, thereby completing the division of the circuit board.

[0010] Through the above-mentioned arrangement, by arranging a gong cutter assembly under the circuit board, after the gong cutter separates the circuit board, the debris generated by the gong cutter separating the circuit board will automatically fall downward due to gravity, and there is no need to clean it repeatedly, thereby improving the work efficiency of circuit board forming and saving energy at the same time.

[0011] In the utility model, the clamping assembly includes two cross bars slidably arranged on the top of the base, a protrusion is fixedly arranged on one side of the cross bars close to each other, a slot is opened on the side facing the protrusion, and a plurality of through screw holes are spaced apart on the top wall of the slot, and a bolt is inserted into each screw hole.

[0012] In the utility model, a bidirectional screw is rotatably arranged on both sides of the opening at the top of the base, the axial direction of the bidirectional screw is perpendicular to the length direction of the cross bar, the two ends of the cross bar are respectively fitted on the two bidirectional screws, and the two cross bars are respectively located at the positive and negative thread sections of the bidirectional screws, the two bidirectional screws are connected by a transmission belt, and a second motor is fixedly arranged on the outer side wall of the base, and the second motor is transmission-connected to one of the bidirectional screws.

[0013] The principle and effect of this technical solution:

[0014] Before installing the fixture, adjust the distance between the two cross bars by turning the two bidirectional screws so that the two ends of the base can be located above the bottom wall of the slot respectively. Then place the two ends of the base on the bottom wall of the slot, and turn the bolt located above the base so that the bottom of the bolt presses the top of the base.

[0015] Through the above arrangement, by adjusting the distance between the two cross bars, the clamping assembly can fix bases of various sizes, thereby broadening the applicable scenarios of the utility model.

[0016] In the utility model, the displacement mechanism includes a moving frame, a Y-axis linear module and a Z-axis linear module, wherein the moving frame is rotatably provided with travel gears at both ends, the Y-axis linear module is mounted on the moving frame, the Z-axis linear module is mounted on the Y-axis linear module, and the first motor is mounted on the Z-axis linear module. Through the above arrangement, the first motor and the gong cutter are moved in the inner cavity along the three directions of the X, Y and Z axes respectively by utilizing the cooperation of the moving frame, the Y-axis linear module and the Z-axis linear module.

[0017] In the present utility model, the locking mechanism includes a plurality of limiting blocks rotatably arranged on the top of the base, and the bottom of the limiting block can abut against the top of the movable seat.

[0018] Principle and effect of this technical solution:

[0019] Before rotating the movable seat, rotate the limiting block to move the whole limiting block outside the limiting groove; when rotating the movable seat into the limiting groove and it needs to be fixed, rotate the limiting block so that one end of it moves into the projection range of the limiting groove. During this process, the bottom of the limiting block pushes the movable seat to press tightly against the circuit board.

[0020] Through the above settings, the purpose of connecting the base and the movable seat through the locking mechanism is achieved. At the same time, the movable seat presses tightly against the circuit board, avoiding the displacement of the circuit board in the vertical direction when the router processes the circuit board, and improving the forming quality of the circuit board.

[0021] In the present utility model, a dust suction mechanism is further included. The dust suction mechanism includes a ventilation hose. The air inlet end of the ventilation hose is fixedly arranged on the side wall of the first motor, and the air inlet of the ventilation hose is located below the router. The other end of the ventilation hose is communicated with a suction fan.

[0022] Principle and effect of this technical solution:

[0023] When the router processes the circuit board, some chips with smaller mass may adhere to the surface of the circuit board. While rotating the router, drive the suction fan to work, forming a negative pressure below the contact position between the router and the circuit board, thereby sucking away the chips attached to the surface of the circuit board.

[0024] Through the above settings, the cleaning ability of the chips on the surface of the circuit board can be further improved, and thus the forming effect of the circuit board can be improved.

[0025] In the present utility model, anti-slip teeth are respectively arranged on the bottom wall of the card slot and the bottom walls at both ends of the base and are mutually matched. Through the above settings, the base can be prevented from moving along the length direction of the cross bar, and the stability of the device during operation can be improved.
