Description

Technical Field

[0001] The present invention relates to the technical field of back bolt drilling, and in particular to an automated back bolt drilling device, method and medium. Background Art

[0002] In the field of stone processing, bolt drilling is a key process. With the continuous prosperity of the stone industry, stone processing plants have increasingly higher requirements for the efficiency and precision of bolt drilling.

[0003] Traditional back-bolt drilling devices mostly use commercial systems, which are highly closed and lack openness. Before processing, professional technicians must perform tedious size verification work on each plate according to the printed drawings, and program input on the equipment host computer before the back-bolt drilling equipment can start processing operations. However, since the drilling hole positions of each plate are different, this means that in each preparation process, technical workers need to repeat the programming input operation, which not only greatly consumes manpower and time, resulting in low production efficiency, but also increases the company's labor costs.

[0004] In addition, the existing back bolt drilling device has serious deficiencies in determining the processing origin. It does not have the function of automatically determining the processing origin, and can only rely on professional and technical workers to manually mark the processing origin through measuring tools. In the manual measurement process, it is inevitable to introduce large uncertainties and errors due to various factors such as the worker's operating level, the accuracy of the measuring tool, and the measuring environment. This makes the actual plate hole position often deviate from the design drawing, which cannot meet the high-precision processing requirements, thus affecting product quality, and may even cause product scrapping, causing economic losses to the company.

[0092] On the basis of the above embodiment, in an optional embodiment of the present invention, step S08 specifically includes steps S081 to S086.

[0093] S081. Determine whether the design origin of the workpiece is the center point of the workpiece according to the information to be processed.

[0094] S082. When it is determined that the design origin is the center point, the shape of the workpiece is obtained according to the edge information.

In other embodiments, the first limit switch 14 and the second limit switch 15 can also use limit switches of other structures, and the present invention does not make specific limitations on this, as long as it can detect that the workpiece and the three moving axes move to the preset position.

[0115] Preferably, the auxiliary device 7 further comprises a cooling water valve 19. The cooling water valve 19 is configured to spray water to the drill hole when the back-bolt drill bit is working, so as to dissipate heat for the tool.

[0116] On the basis of the above-mentioned embodiment, in an optional embodiment of the present invention, the automated back-bolt drilling equipment further comprises a control device electrically connected to the execution device 5, the detection device 6 and the auxiliary device 7. The control device comprises a microcontroller development board 1 electrically connected to the drill mechanism 8, the jacking mechanism 9, the clamping mechanism 10, the three-axis moving mechanism, the tool setting instrument 13, the first limit switch 14 and the distance measuring mechanism 17, and a communication mechanism and a screen 3 electrically connected to the microcontroller development board 1.

The mouse, keyboard and lamp peripherals can be removed through the touch screen, and the file server 4 directly reads the processing file through wireless communication through the PCB antenna 2, making the appearance of the automated back-bolt drilling equipment more concise. The microcontroller development board 1 is connected to the screen 3, the code scanning mechanism 16 and the distance measuring mechanism 17 through a serial communication interface, and the microcontroller development board 1 is connected to the drill mechanism 8, the lifting mechanism 9, the clamping mechanism 10, the reaming mechanism 11, the driving mechanism 18 and the cooling water valve 19 through a relay or a driving circuit.

The microcontroller development board 1 is connected to the tool setting instrument 13, the first limit switch 14 and the second limit switch 15 through a digital or analog input port.

[0118] In summary, during the operation of the automatic back-bolt drilling method, the lifting mechanism 9 first lifts the roller component, and then the driving mechanism 18 drives the roller component to rotate to transport the plate to the designated processing area. When the plate reaches the preset position, the first limit switch 14 is triggered, the driving mechanism 18 stops immediately, the lifting mechanism 9 drops down and puts down the roller component, and then the clamping mechanism 10 secures the plate in the processing area.

[0119] Then, the microcontroller development board 1 automatically issues a command to control the servo motor 12 to move the X, Y, and Z axes to their respective second limit switches 15 for reset operation, and then moves to the tool setting instrument 13 for tool setting, recording the current position of the tool tip. After the tool setting is completed, the barcode scanning mechanism 16 reads the barcode information on the edge of the plate and transmits it to the microcontroller development board 1.

[0120] The microcontroller development board 1 is equipped with an antenna 2, which communicates with the file server 4 via Wi-Fi, automatically downloads and parses the corresponding processing files according to the barcode information, and performs automated drilling operations according to the file information. In this process, the distance measuring mechanism 17 is activated, moves along the preset path to detect the edge of the plate, and calculates the processing origin of the plate. Then, based on the processing file information and the processing origin information, the device will automatically complete the back bolt drilling process. The specific operation includes: starting the drill mechanism 8 to rotate the tool, and simultaneously starting the cooling water valve 19 to dissipate heat; then, the servo motor 12 drives the X and Y axes to move above the hole to be processed, and the Z axis slowly descends for preliminary drilling. When the drilling reaches the predetermined depth, the reaming mechanism 11 is started, so that the drill mechanism 8 swings at a set angle, completes the reaming action, and forms a complete back bolt hole. Subsequently, according to the processing file information, the above logic is repeated to complete the processing of all holes. In addition, the screen 3 can display the processing information in real time, which is convenient for users to monitor and operate.
