The working principle of the drilling control method for the circuit board is described in the following with reference to fig. 1 and fig. 2:
after the circuit board is cut, the circuit board is conveyed to a feeding area of a two-dimensional code drilling machine through a conveyor belt, the machine feeding area senses the circuit board through a sensor, the circuit board is fixed on a board conveying device through a board beating device and then conveyed to a drilling area of the machine, the drilling machine automatically generates a unique two-dimensional code at the same time, the two-dimensional code is converted into drilling file data, the two-dimensional code is simultaneously uploaded to a client server or production management control software for backup, the circuit board is conveyed to the drilling area and then fixed on a board again through a mechanism (meanwhile, the board conveying mechanism returns to the machine feeding area to receive the board again to wait for the board after the board is drilled in the drilling area and then to be conveyed to a discharging area to indicate feeding), then the drilling machine drills out the minimum drilling number of 10 x 10 matrix two-dimensional codes at the fixing position of the circuit board, and conveys the circuit board to the discharging area after the board is drilled out (the sensor of the discharging area senses the, and the discharging area sends the material to the next production process, before entering each different next process, the drilled holes on the circuit board are scanned by using a scanning gun or a camera and decoded into character information and uploaded to a client server or production management control software until the circuit board is produced (if the circuit board is a small board, a client can read the code and mark the code on each small board by using a laser marking or silk screen printing and the like in a proper process section). The customer can track the production time of the circuit board drilled with the matrix two-dimensional code graph in each process and the information of which equipment produces the circuit board through production management software, and the like, so that the customer can conveniently track production and manage and control quality.
Wherein, the upper computer transmits the board to the prepositioning work area which is butted with the board. When a sensor at the joint of the prepositioning working area and the upper computer senses that a board enters, a transmission motor of the prepositioning working area is started, a stepping motor rotates to drive a transmission conveyor belt to work to carry out plate receiving action, the conveyor belt conveys the board to a preset position, the in-place sensor senses that the board exists, the feeding stop cylinder rises at the moment, and the transmission belt stops transmitting according to specified delay time. The plate receiving station is moved to a preset position of a prepositioning working area by a servo motor through a synchronous belt. The lifting platform cylinder (with a secondary lifting function) executes primary lifting action, so that the substrate platform is lifted to be flush with the table top of the pre-positioning working area, and the left blocking cylinder fixed on the joint plate platform is kept in a disengaged state and lifted. Then, the mounting plate of the left blocking cylinder is contracted through the action of the cylinder. The conveyer belt motor begins to operate, makes the board on the conveyer belt transport near the cylinder pin that blocks that is close to the fishplate bar platform, and the sensor on the fishplate bar platform senses the board this moment, conveyer belt stall. The right blocking cylinder of the joint plate platform is driven by the cylinder to be close to the plate from a position far away from the plate until the plate is clamped between the left blocking cylinder and the right blocking cylinder. The rear blocking rod on the joint plate platform drives the fixed front blocking edge which pushes the plate to the pre-positioning area by using the blocking rod. The left and right blocking cylinders contract and press down to clamp the plate materials, so that the plate materials are fixed on the plate receiving platform. And the lifting platform cylinder executes secondary lifting action to separate the plate fixed on the plate receiving platform from the conveying belt.
The plate receiving platform is driven by a servo motor to move to a drilling work area formulation position, the lifting platform cylinder performs a first-level descending action to enable the plate receiving platform to be level with the work area work platform, and the work area clamping plate cylinder performs a pressing and contracting action to clamp a plate. And the left blocking cylinder and the right blocking cylinder on the joint plate platform perform ascending action, and then the left blocking cylinder and the right blocking cylinder are far away from the plate through the action of the cylinders. And after the left and right blocking cylinders are far away from the plate, the blocking cylinders contract and descend. Meanwhile, the cylinder of the lifting platform performs a two-stage descending action, and the joint plate platform descends to be lower than the working table surface of the working area. At this time, the drilling machine starts the drilling process according to the specified data.

The plate receiving platform is connected with the plate receiving platform through the connecting plate, the synchronous movement state is kept, when the plate receiving platform is far away from the working area workbench and moves towards the pre-positioning working area, the plate receiving platform moves simultaneously, and the plate receiving platform stops at the designated position of the working area.
The plate connecting platform lifting cylinder executes primary lifting action to enable the plate connecting platform to be level to the working area workbench, the left clamping plate cylinder on the plate connecting platform keeps a contraction state, and the cylinder drives the left clamping plate cylinder mounting plate to be far away from the plate. And the left clamping plate cylinder of the joint plate platform rises to wait. After drilling of the drilling machine is completed, the left clamping plate cylinder of the joint plate platform drives the clamping plate cylinder mounting plate to enable the left clamping plate cylinder to be close to the plate through cylinder movement, the clamping plate cylinder contracts and presses downwards, and the plate is fixedly clamped on the joint plate workbench. And the plate receiving platform lifting cylinder executes secondary lifting action, and the plate receiving platform rises to lift the plate fixed on the plate receiving platform and separate from the working area workbench. The joint plate workstation moves to receive the board workspace assigned position, and joint plate platform lift cylinder carries out the one-level descending action, makes joint plate platform and receipts material workspace mesa keep level. The left clamping plate cylinder of the joint plate platform rises, the cylinder acts to drive the mounting plate of the left clamping plate cylinder of the joint plate platform to be far away from the plate, and the plate loosening and placing actions are completed. The left clamping plate cylinder of the connecting plate platform descends, and meanwhile, the connecting plate platform lifting cylinder executes secondary descending action, so that the connecting plate platform descends and is lower than the table top of a plate receiving working area.
And after the plate is placed, the conveyor belt in the plate receiving area works, the plate placed in the plate receiving area is transported to a lower computer, and when the plate is separated from the plate receiving area, the sensor in the plate receiving area senses that no plate exists, and the conveyor belt stops acting.
The plate receiving platform is connected with the plate receiving platform through the connecting plate, the synchronous movement state is kept, and the plate receiving platform transports the plate materials positioned in the pre-positioning working area to the drilling working area when the plate receiving platform moves to the plate receiving working area. When the plate receiving platform places the positioned plate materials in the drilling working area and returns to the pre-positioning working area after the positioning is finished, the plate receiving platform moves the drilling working area to execute corresponding actions and waits for the drilling machine to complete drilling.
