Description

Technical Field

[0001] This invention relates to the field of electronic component processing, specifically to a device for separating circuit boards of an air flow meter. Background Technology

[0002] An air flow meter is a monitoring device used to monitor the amount of air entering the intake manifold of a car engine. The circuit board of this device is usually made by soldering electronic components on a large circuit board to obtain a large board composed of multiple identical circuit boards. These individual circuit boards need to be separated and then installed into their respective housings.

[0003] Traditionally, board separation is done manually by holding the circuit board and aligning its V-groove with the saw blade. The saw blade is then activated, causing it to move and separate the board. This method is inefficient, so automated equipment is now commonly used. However, our existing board separation equipment lacks specificity, requiring multiple passes and lacking corresponding positioning equipment, making it prone to misalignment. Furthermore, the separation process generates significant dust, and adding specialized dust removal equipment would increase costs. This is also detrimental to cost reduction when multiple machines are needed. Therefore, we require a dedicated board separation device specifically designed for our products. Summary of the Invention

[0004] The purpose of this invention is to provide an air flow meter circuit board splitting device to solve the problems mentioned in the background art.

[0005] An air flow meter circuit board separation device includes a base plate, a sliding plate, a positioning mold, and a rotating assembly. The base plate is equipped with a translation device that drives the sliding plate to move linearly on the base plate. A frame is fixedly connected to the base plate, and the frame is equipped with the separation device and two waste collection devices. The separation device separates the circuit boards on the positioning mold. The positioning mold is rotatably connected to the sliding plate and is driven to rotate by the rotating assembly. The waste collection devices use the rotation of the rotating shaft in the separation device as a driving source to collect waste from the circuit boards separated on the positioning mold.

[0006] Preferably, the positioning mold includes a lower plate, an upper plate, and a cover plate. The upper plate has electromagnets and L-shaped positioning blocks at its four corners. The cover plate is attracted to the upper plate by the electromagnets to press the circuit board. Both the upper plate and the cover plate have several horizontal and vertical reserved slots, which correspond to the board separation lines of the circuit board. A cavity is formed between the lower plate and the upper plate. Several through slots communicating with the cavity are provided in the reserved slots. An air extraction pipe is provided at the bottom of the lower plate. The air extraction pipe passes through the slide plate and is rotatably connected to the slide plate.

[0007] Preferably, the rotating assembly includes a motor and a worm gear. The worm gear is fixedly connected to the air extraction pipe. The motor is fixedly connected to the bottom of the slide plate. The output shaft of the motor is fixedly connected to a worm, which meshes with the worm gear.

[0008] Preferably, the translation device includes a linear module and guide rails. Two guide rails are fixedly connected to the base plate, and the base plate is slidably connected to the guide rails. The linear module is fixedly connected to the base plate, and its slide is fixedly connected to the base plate.

[0009] Preferably, the plate separating device includes a rotating shaft and a second motor. The rotating shaft is fixedly connected to the frame, and several saw blades are fixedly connected to the rotating shaft. A sprocket is fixedly connected to one end of the rotating shaft. The second motor is fixedly connected to the top of the frame, and its output shaft is also fixedly connected to a sprocket. The two sprockets are connected by a chain.

[0010] Preferably, the waste collection device includes an elliptical cam and an air suction cylinder. The elliptical cam is fixedly connected to a rotating shaft and located between two adjacent saw blades. The major axes of the two elliptical cams are perpendicular to each other. The air suction cylinder is fixedly connected to the top of the frame, and its piston rod passes downward through the frame and is fixedly connected to a wheel frame. A roller is rotatably connected to the wheel frame, and the roller is in tangential contact with the elliptical cam. A spring is provided on the piston rod between the wheel frame and the frame. The top of the air suction cylinder is provided with an air suction pipe and an air discharge pipe. Both the air suction pipe and the air discharge pipe are provided with one-way valves. The air suction pipe is connected to a suction pipe through a rotary joint, and a filter cylinder is provided on the connecting pipe between the air suction pipe and the suction pipe. A filter screen is provided inside the filter cylinder.

[0011] The advantages of this invention are:

[0012] The rotation of the shaft drives the piston rod to move up and down, thereby generating an outward suction force in the suction pipe without adding additional vacuuming equipment. Then, the dust and debris generated at the dividing point can be collected through the reserved cavity between the upper and lower plates, along with the reserved slots and through slots.

[0013] By setting a rotatable positioning mold and using a multi-blade board separating device, the circuit board can be rotated after one pass, so that the circuit board can be passed again on the return trip. The board can be separated in one round trip. Compared with using general equipment, it is more efficient and more suitable for the batch separation of the same type of circuit board.

[0032] In this embodiment, the plate separating device 7 includes a rotating shaft 71 and a second motor 72. The rotating shaft 71 is fixedly connected to the frame 6.

The second motor 72 is fixedly connected to the top of the frame 6, and its output shaft is also fixedly connected to a sprocket 74. The two sprockets 74 are connected by a chain.

[0033] In this embodiment, the waste collection device 8 includes an elliptical cam 81 and an air suction cylinder 82. The elliptical cam 81 is fixedly connected to the rotating shaft 71 and located between two adjacent saw blades 73. The major axes of the two elliptical cams 81 are perpendicular to each other.

[0034] Working process and its principle:

[0035] During the separation process, the circuit board 9 is first placed between the four positioning blocks 311 on the upper plate 32. The positioning blocks 311 are used for the initial positioning of the circuit board 9. Then, the cover plate 33 is placed on the circuit board 9, and the electromagnet 34 is activated. The electromagnet 34 can attract the cover plate 33, thereby pressing the cover plate 33 tightly against the four sides of the circuit board 9.

[0036] The area of ​​the circuit board 9 to be cut corresponds to the reserved slot 35. The second motor 72 and the linear module 51 are started. The slide plate 2 moves towards the saw blade 73. The second motor 72 drives the rotating shaft 71 to rotate through two sprockets 74, which in turn drives the saw blade 73 to rotate. The reserved slot 35 can be used to accommodate the saw blade 73. The saw blade 73 passes through the reserved slot 35 and cuts the circuit board 9 above the reserved slot 35.

[0037] The rotation of the shaft 71 also drives the elliptical cam 81 to rotate, causing the roller 85 to move up and down in contact with the elliptical cam 81, thereby driving the piston rod 83 to slide inside the suction cylinder 82. Since the major axes of the two elliptical cams 81 are perpendicular to each other, that is, the movement trajectories of the two piston rods 83 at the same time are opposite, ensuring that one suction cylinder 82 is always in the suction state. When the suction cylinder 82 sucks in air, the airflow enters from the reserved groove 35, and then enters the cavity 38 through the through groove 36, so that the cutting dust generated at the reserved groove 35 can enter the cavity 38 and be finally collected by the filter cylinder 87.

[0038] When the vertical cutting of circuit board 9 is completed, the linear module 51 pauses, the motor 41 rotates, and the worm gear 43 drives the worm wheel 42 to rotate 90 degrees, so that the originally horizontal groove to be cut is rotated to a vertical state. Then the linear module 51 restarts, driving the slide plate 2 to return, thereby cutting the cutting groove in another direction on circuit board 9. After the cutting is completed, the solenoid valve is closed, and circuit board 9 can be taken out.

[0039] The slide plate 2 can divide the circuit board 9 into multiple individual circuit boards 9 by moving back and forth once. Compared with the existing general-purpose board splitting equipment, the board splitting efficiency is higher and the structure is simple. It is suitable for the batch splitting of the same type of circuit board 9.

[0040] As is known from common technical knowledge, an invention can be realized through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of the invention or equivalent to the invention are included in the invention.
