Description

TECHNICAL FIELD

[0001] The application relates to the field of PCB controlled depth drilling, in particular to a 5G communication PCB controlled depth drilling device and process. BACKGROUND

[0002] PCB controlled depth drilling is a technology for accurately controlling the drilling depth in the manufacturing process of a printed circuit board (PCB). The principle is to use the contact of a drill bit to the surface of the PCB to send a conductive signal, which is used as a zero interface to process a specified drilling depth. When the drill tip contacts the copper foil, a weak current is generated, and the device accurately senses the change in the small current to obtain accurate information about the height position of the board surface, and then performs drilling operation according to the pre-set drilling depth. When the pre-set depth is reached, the device stops drilling. The residual thickness of the processed board is controlled to achieve hole depth drilling, and the residual thickness is defined as the height from the table to the processing position of the drill bit. The actual drilling depth is equal to the total thickness of the board minus the residual thickness. A first coil is arranged at a predetermined position in the PCB, and a second coil is arranged on the drill bit. One of them is an excitation coil, and the other is a power coil. The drill bit is controlled to drill from the first surface of the PCB at the predetermined drilling position to the predetermined position. When the inductive electromotive force / inductive current detected by the sensing device is greater than or equal to a predetermined threshold value, the drill bit is stopped from sinking.

[0003] With the development of science and technology, 5G communication has also been applied to PCB controlled depth drilling. 5G communication has high frequency and fast data transmission rate, and has extremely strict requirements on signal integrity. For example, in the millimeter wave band, the signal transmission loss reaches 15%, resulting in a signal attenuation of 7. The controlled depth drilling needs to achieve extremely high precision, and the current back drilling depth control precision can reach ±6 mil, to ensure the accuracy of the drilling depth, reduce signal reflection, scattering and delay, and ensure signal quality. The electronic components on the 5G communication PCB are more dense, and the wiring space is tight, so small-diameter controlled depth drilling is needed to realize more via connections, while ensuring the hole wall quality and drilling precision to meet the requirements of high-density interconnection.

[0004] However, when drilling the existing PCB, in order to realize the electrical connection between the layers of the circuit board or the structural requirements, drilling needs to be performed back and forth on both surfaces of the PCB. The existing PCB is generally fixed on the processing table by adhesive tape, and cannot be turned over during drilling. Generally, the PCB is drilled one side at a time. When drilling the upper and lower holes needs to be coaxial, a large error will be generated, affecting the stability of subsequent circuit transmission. Therefore, a 5G communication PCB controlled depth drilling device and process are proposed. SUMMARY

[0017] A 5G communication PCB depth control drilling process, comprising the following steps:

[0018] Step one: first determine the thickness of the PCB to be drilled, then control the push rod motor to adjust the height of the lower clamping plate, so that when the PCB is clamped between the lower clamping plate and the upper clamping plate, the middle surface of the thickness of the PCB is coplanar with the axis of the rotating shaft one, then control the two side bases to slide towards each other until the lower clamping plate and the upper clamping plate on the two side bases can clamp the two side edges of the PCB;

[0019] Step two: control the two ends of the bidirectional telescopic piece to shrink synchronously, drive the two side slides to move towards each other, and then act on the lower clamping plate and the upper clamping plate through the leveling assembly, so that the lower clamping plate and the upper clamping plate can be parallel to the machining plane, and the PCB clamped by the lower clamping plate and the upper clamping plate can also be parallel to the machining plane, and then the PCB is drilled based on the G communication control drilling module;

[0021] Step four: when the PCB needs to be turned over for processing, the two side slides of the slide frame are driven to move away from each other, the horizontal limiting of the leveling assembly on the lower clamping plate and the upper clamping plate is cancelled, the bevel seats are lowered, and the bevel seats are gradually driven upwards through the linkage assembly to act on the ratchet wheel, so that the ratchet wheel is driven to rotate, and the PCB can be turned over;

[0024] The beneficial effects of the present application are:

[0025] 1. The technical scheme of the present application can clamp the two sides of the PCB by the cooperation of the lower clamping plate and the upper clamping plate on the two side bases, and the height of the lower clamping plate can be adjusted by the push rod motor, so that the middle surface of the PCB thickness can be coplanar with the axial direction of the shaft during clamping, facilitating the turning of the PCB during processing by the rotation of the shaft. By the leveling assembly, the PCB can be limited to a horizontal state after being clamped by the lower clamping plate and the upper clamping plate, thereby improving the processing precision. Meanwhile, the linkage assembly can drive the inclined angle seat to move upwards, so that the inclined angle seat at the front and rear ends of the PCB can limit it to a state of being centered in front and rear while the leveling assembly levels the PCB, facilitating positioning and processing.

[0026] 2. The technical scheme of the present application can drive the two side slides to move close to each other by the bidirectional extension piece, thereby driving the leveling assembly to level the PCB. When the two side slides are driven to move close to each other, the linkage assembly can drive the two side inclined angle seats to move downwards first, and then drive the mounting seat to rotate by the meshing with the ratchet wheel, thereby realizing the 180° turning of the PCB clamped by the lower clamping plate and the upper clamping plate, and facilitating the drilling of both sides at any time during processing, thereby further improving the processing precision.

[0027] 3. The technical scheme of the present application can drive the two side slides to move close to each other by the bidirectional extension piece, thereby driving the leveling assembly to level the PCB. When the drilling module drills the upward side of the PCB, the linkage assembly can drive the cleaning assembly to move upwards, and the cleaning assembly can clean the side that has been drilled and turned downwards, thereby avoiding the influence of waste on the drilling quality during subsequent turning processing, and improving the drilling quality.
