DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Embodiment 1

[0019] Reference Figure 1-Figure 7 , a PCB board drilling machine intelligent feeding and positioning equipment, including a working component, a lifting component and a pre-alignment component; The working component is used for collecting drilling targets on PCB boards, and the working component includes a pre-alignment input machine 1 and an X-Ray target drilling machine 2 fixedly arranged on one side of the pre-alignment input machine 1; The lifting assembly is used to automatically convey and load incoming PCB boards, and the lifting assembly includes a base frame 4 fixedly arranged on the pre-alignment feeding machine 1 and a transport arm 12 fixedly arranged inside the pre-alignment feeding machine 1; A lifting motor 5 is fixedly connected to the bottom of the base frame 4, a guide rail 6 fixedly connected to the driving end of the lifting motor 5 is fixedly arranged on the base frame 4, a lifting frame 7 slidably connected to the base frame 4 is penetrated through the guide rail 6, carrier positioning cylinders 8 are fixedly arranged on both sides of the lifting frame 7, a material box 9 clamped between two carrier positioning cylinders 8 is arranged on the lifting frame 7, a fixed frame 13 is fixedly connected to the movable end of the transport arm 12, a shaking plate pneumatic cylinder 14 is fixedly arranged on both sides of the fixed frame 13, a color sensor 15 is fixedly arranged on one side of the fixed frame 13, and an extension frame 16 is fixedly connected to the bottom of the two shaking plate pneumatic cylinders 14, and a plurality of vacuum suction cups 17 are fixedly arranged on the extension frame 16; Both sides of the base frame 4 are fixedly provided with a thickness measuring assembly for detecting the thickness of the PCB board. The thickness measuring assembly includes a thickness measuring platform 10 fixedly connected to the base frame 4, and a thickness gauge 11 is fixedly connected to the top of the thickness measuring platform 10; The pre-alignment component is used to automatically pre-align the position of the PCB board after loading, and the pre-alignment component includes two sheet metal bases 18 fixedly connected to the base frame 4 and two laser sensors 19 fixedly connected to both sides of the sheet metal base 18; A Teflon fixture 20 fixedly connected to the sheet metal base 18 is disposed above the two laser sensors 19 and inside the sheet metal base 18. Three support columns 21 are fixedly disposed inside the base frame 4. A movable track 22 is fixedly disposed on the top of the three support columns 21. A vacuum pump 23 is slidably connected to the movable track 22. A vacuum suction cup 24 connected to the vacuum pump 23 is fixedly disposed on the top of the vacuum pump 23. In this embodiment, a Teflon fixture 20 fixedly connected to the sheet metal base 18 is provided above the two laser sensors 19 and inside the sheet metal base 18, three support columns 21 are fixedly provided inside the base frame 4, a moving track 22 is fixedly provided on the top of the three support columns 21, a vacuum pump 23 is slidably connected to the moving track 22, and a vacuum suction cup 24 connected to the vacuum pump 23 is fixedly provided on the top of the vacuum pump 23; Furthermore, the material box 9 filled with PCB boards is stably placed on the lifting frame 7, and the position sensor on the carrier positioning cylinder 8 starts to work to detect the placement position deviation of the material box 9. According to the data fed back by the sensor, the control system calculates the deviation amount and sends an action command to the carrier positioning cylinder 8. The piston of the carrier positioning cylinder 8 extends or retracts to push the material box 9 for fine adjustment until the material box 9 is accurately positioned at the preset position. At the same time, the transport arm 12 moves the fixed frame 13 to the top of the material box 9 according to the preset motion trajectory and under the command of the control system through the servo motor at the joint. The air pressure valve of the plate-shaking pneumatic cylinder 14 is opened, and compressed air enters the cylinder to push the piston downward, thereby driving the extension frame 16 to descend. When the vacuum suction cup 17 contacts the surface of the PCB board, the vacuum generator is started to form a negative pressure inside the vacuum suction cup 17, tightly adsorbing the PCB board. The air pressure valve of the plate-shaking pneumatic cylinder 14 moves in the opposite direction, and the piston retracts, driving the extension frame 16 and the adsorbed PCB board to rise. The transport arm 12 moves again to transport the PCB board to the loading station of the pre-alignment input machine 1, completing a loading process. Repeat this step to achieve continuous automatic loading, greatly improving the loading efficiency and reducing the manual operation cost. In addition, after the transport arm 12 places the PCB board on the thickness measuring platform 10, the detection probe of the thickness gauge 11 starts to work. The thickness gauge 11 uses the principle of laser ranging or ultrasonic ranging to transmit a detection signal to the PCB board. After the signal is reflected back, the thickness gauge 11 calculates the thickness of the PCB board according to parameters such as the round-trip time or phase difference of the signal. The thickness gauge 11 transmits the measured thickness data to the control system in real time through the data line. The control system compares the received thickness data with the preset standard thickness range. If the thickness is not within the standard range, the control system immediately triggers an alarm device, such as an audible and visual alarm, to prompt the operator to handle it, so as to avoid subsequent processing errors caused by thickness problems. The PCB board that has completed the thickness detection is transported and moved to the pre-alignment component. The two laser sensors 19 in the sheet metal base 18 simultaneously emit laser beams. The laser beams are irradiated on the edge contour of the PCB board at a certain angle. The laser sensor 19 receives the reflected laser signal and converts it into an electrical signal and transmits it to the control system. The control system calculates the position deviation of the PCB board according to the signals transmitted by the two laser sensors 19, including translation deviation and rotation deviation. The control system sends an action instruction to the drive device of the Teflon fixture 20 according to the calculated deviation. The drive device of the Teflon fixture 20 is activated to fine-tune the PCB board to achieve a precise pre-alignment state, providing a precise positioning basis for subsequent target drilling work, improving target drilling accuracy, and reducing scrap rate.

[0020] Reference Figure 8 and Fig. 9Compared with the first embodiment, in this embodiment, an X-Ray detection component for detecting the PCB board is arranged inside the base frame 4, and the X-Ray detection component includes a fixed base frame 25 fixedly connected to the inside of the base frame 4, a mounting frame 26 is slidably arranged on the fixed base frame 25, a moving track 27 is arranged on the fixed base frame 25, one end of the moving track 27 is fixedly connected to the fixed base frame 25, and the other end of the moving track 27 is fixedly connected to the mounting frame 26, an image intensifier 28 is fixedly connected to the mounting frame 26, a ray blocking plate 30 is fixedly connected to the top of the mounting frame 26, a lifting cylinder 31 is fixedly connected to the top of the mounting frame 26, and an X-ray light tube 29 is fixedly connected to the lifting end of the lifting cylinder 31.

[0021] In this embodiment, the pre-alignment platform PCB uses program-specific parameters, and the PCB-specific MARK target will be moved into the X-ray effective field of view to capture two or more targets. By comparing the captured MARK target graphics with the program preset, the software calculates the deviation of the current position of the product, compares the product attributes, and outputs the data to the control program of the transport arm 12.

[0022] Furthermore, after receiving the deviation data calculated from the X-ray image unit, the data is sent to the transport arm 12 through the PC and PLC for mechanical adjustment, so that the preset drilling target of the PCB is within the effective field of view of the X-ray drilling machine: the maximum field of view is 10*10mm, and the interface signal is interacted with the X-RAY drilling machine 2 through the pre-alignment input machine 1, and the IO signal is sent to the X-ray drilling machine, so that after the X-ray drilling machine receives the signal from the pre-alignment input machine 1, it performs mechanical movement and PCB processing operations according to a specific program. Embodiment 3

[0023] Reference Figure 10-Figure 14 Compared with the first and second embodiments, in the present embodiment, a fixing plate 32 is fixedly connected to one side of the base frame 4 close to the lifting assembly, and a slicing assembly is provided on the fixing plate 32 for slicing two plates adsorbed by static electricity during the loading process. The slicing assembly includes a fixing rod 33 fixedly connected to the fixing plate 32, a baffle 34 rotatably connected to the fixing plate 32 is sleeved on the outer side of the fixing rod 33, a torsion spring 35 is fixedly connected between the inner wall of the baffle 34 and the fixing rod 33, a fixing block 36 is fixedly connected to the bottom of the baffle 34, a swing rod 37 is rotatably connected to the bottom of the fixing block 36, a spring 38 is fixedly connected between the top of the swing rod 37 and the fixing block 36, a suction cup 39 is fixedly connected to the bottom of the swing rod 37, an inner bin 40 is provided on one side of the interior of the fixing plate 32, and a negative pressure assembly for sucking and releasing air from the suction cup 39 is provided inside the inner bin 40.

[0024] The negative pressure assembly includes a threaded rod 41 which is rotatably connected to the interior of the inner bin 40 and fixedly connected to the baffle 34, a nut 42 is threadedly sleeved on the threaded rod 41, an air box 43 is fixedly connected to the bottom of the inner bin 40, an air pumping rod 44 which is fixedly connected to the nut 42 on one side of the air box 43 through a piston sliding connection, and an air guide hose 45 which is connected to the suction cup 39 is fixedly connected to the other side of the air box 43.

[0025] In this embodiment, when two plates stuck together due to electrostatic adsorption move to the sheeting assembly position along with the loading process, the baffle 34 on the fixed plate 32 first contacts the plates, and the plates push the baffle 34 to rotate around the fixed rod 33. The torsion spring 35 on the fixed rod 33 is stretched to store elastic potential energy. When the baffle 34 rotates, it drives the fixed block 36 to move together.

[0026] Furthermore, the fixed block 36 is connected to the swing rod 37 through a pin shaft. Under the buffering action of the spring 38, the swing rod 37 moves downward, causing the suction cup 39 to gradually approach the plate. At the same time, the rotation of the baffle 34 drives the threaded rod 41 to rotate. The nut 42 on the threaded rod 41 moves axially along the threaded rod 41 under the action of the thread. The nut 42 pushes the air pump 44 to perform a piston movement in the air box 43. The gas in the air box 43 is extracted through the air guide hose 45, so that a negative pressure is formed inside the suction cup 39. The suction cup 39 adsorbs the lowest plate. As the baffle 34 continues to rotate, the adhered plates are successfully separated, ensuring the accuracy of each feeding, avoiding processing errors caused by overlapping plates, and improving production stability.
