Description

Technical Field

[0001] The utility model relates to the technical field of PCB drilling, in particular to an automatic drilling target device for X-ray transmission of circuit boards. Background Art

[0002] The Chinese name of PCB is printed circuit board, also known as printed wiring board. It is an important electronic component, a support for electronic components, and a carrier for electrical interconnection of electronic components. Since it is made by electronic printing technology, it is called "printed" circuit board.

[0003] A PCB drilling machine is a machine used in the drilling process of PCB processing. Small holes must be drilled on the PCB before inserting components so that the pins of the components can be inserted, or to conduct the circuits on different layers up and down. As the integration degree of PCB boards is getting higher and higher, the quality requirements for the hole diameter are also getting higher and higher.

[0004] Among them, the utility model with the application number CN202223598626.6 discloses a drilling machine for PCB production, which relates to the technical field of drilling equipment. The utility model includes a base plate and a mounting convex rail fixedly arranged on the top surface of the base plate. An installation base is mounted on the mounting convex rail. A backing plate is fixedly arranged on the top surface of the installation base. An installation base column is fixedly arranged on one side of the base plate. A drilling group is fixedly installed on the side wall of the installation base column close to the installation base, and the drilling group is directly opposite to the top surface of the backing plate. A positioning component acting on the top surface of the backing plate is mounted on the installation base column. Compared with the existing one, this device pushes the movable frame through an electric push rod, so that the movable frame slides down along the limit vertical frame. At this time, the extrusion piece on one side of the movable frame will squeeze the circuit board, so that the circuit board can be stably placed on the backing plate. At this time, start the drilling group to drill the circuit board, which can prevent the circuit board from occurring slight deviation and jitter, and ensure the safety and stability of the circuit board production.

[0005] In the above solution, after drilling, the PCB board needs to be unloaded. The existing unloading method is to use belt conveying for unloading. Since belt conveying needs to occupy the surface space of the equipment, and some large PCB boards require a large amount of space, it will affect the layout of other mechanical equipment.

[0049] The present utility model will be described in detail below with reference to the accompanying drawings.

[0050] As Figures 1-9 shown, an automatic drilling target device for X - ray transmission of a circuit board includes a drilling platform 10. The drilling platform 10 is provided with a drilling device 10, and the drilling platform 10 is provided with a drilling work plate 61 for sliding support of the PCB board.

[0051] The drilling device 10 includes a pair of drilling modules. The two drilling modules can simultaneously perform drilling operations on the PCB board, further improving the efficiency.

[0052] The drilling device 10 further includes a bottom work plate 36. The bottom work plate 36 is horizontally provided with a linear module and a bottom guide rail 37 parallel to the linear module. The bottom work plate 36 is slidably installed with a pair of bottom support plates 38 through the bottom guide rail 37. The drilling modules are respectively installed on the bottom support plates 38. The two drilling modules can approach or move away from each other under the drive of the linear module to drill PCB boards of different sizes.

[0053] The drilling module includes a drilling tool 20 on one side of the PCB board. On the other side of the PCB board, there is a guide cylinder 22. The guide cylinder 22 is provided with a guide drilling 23 for the drilling tool 20 to guide into. The guide drilling 23 of the guide cylinder 22 is provided with a strip 17 through which the drilling tool 20 passes during drilling.

[0054] The PCB board is located between the drilling tool 20 and the guide cylinder 22. The strip 17 is attached to the guide drilling 23 of the guide cylinder 22, and the PCB board is also attached to the strip 17. During drilling, after the drilling tool 20 passes through the PCB board, the drilling tool 20 simultaneously passes through the strip 17 and enters the guide drilling 23 of the guide cylinder 22. The strip 17 cooperating with the guide cylinder 22 can press the hole position of the PCB board. When the drilling tool 20 passes through, the hole position will not be deformed. With the buffering of the strip 17, the generation of burrs can be reduced, and the drilling quality of the PCB board can be improved.

[0055] The strip 17 can prevent burrs from being generated at the hole positions of the PCB board.

[0056] The drilling tool 20 and the guiding cylinder 22 are both longitudinally coaxially aligned. The drilling tool 20 is located below the guiding cylinder 22. During drilling, the drilling tool 20 penetrates the PCB board from bottom to top. The strip 17 cooperates with the guiding cylinder 22 to press against the hole positions at the top of the PCB board. When the drilling tool 20 passes through, the hole positions will not be deformed. With the buffering of the strip 17, the generation of burrs can be reduced, and the drilling quality of the PCB board can be improved.

[0057] Preferably, according to requirements, the positions of the drilling tool 20 and the guiding cylinder 22 can be interchanged. During drilling, the drilling tool 20 penetrates the PCB board from top to bottom; they can also be arranged horizontally, and the drilling tool 20 drills the PCB board by passing through the PCB board from left to right or from right to left.

[0058] Specifically, the punching mechanism further includes a winding mechanism 11 for installing the strip 17. The winding mechanism 11 includes a first winding reel 12 and a second winding reel 13. The strip 17 intermittently moves from the first winding reel 12 to the second winding reel 13. During punching, the second winding reel 13 rotates to wind up the strip 17. Each time a hole is punched, the strip 17 moves a distance greater than the diameter of one hole, so that after the drilling tool 20 passes through the PCB board, it can contact the strip 17. By fitting the strip 17 to the hole positions, burrs on the hole positions of the PCB board can be prevented.

[0059] The punching mechanism further includes a top driving arm 101 for installing the guiding cylinder 22. The top driving arm 101 is equipped with a height adjusting member 19 for adjusting the height of the guiding cylinder 22. The height of the guiding cylinder 22 can be adjusted through the height adjusting member 19 to facilitate adaptation to PCB boards of different thicknesses. One end of the top driving arm 101 is formed with a longitudinal support column, and the bottom of the longitudinal support column is connected to the bottom support plate 38 to realize the longitudinal support of the top support arm 101.

[0060] Preferably, the height adjusting member 19 is a longitudinally arranged lifting cylinder, and the guiding cylinder 22 is installed at the driving end of the lifting cylinder.

[0061] Furthermore, the winding mechanism 11 further includes a plurality of winding wheels 18 installed on the top driving arm 101. The top driving arm 101 is equipped with a sliding table 2 flush with the bottom surface of the guiding cylinder 22. One of the winding wheels 18 is installed on one side of the sliding table 2. The strip 17 can move along the sliding table 2. Driven by the winding wheel 18, the strip 17 can move along the winding wheel 18 and the sliding table 2 and pass through the guiding cylinder 22.

[0062] The sliding table 2 is formed with a through hole 21 coaxially aligned with the guide cylinder 22. The guide cylinder 22 is installed in the through hole 21 such that the bottom of the guide cylinder 22 is flush with the bottom of the sliding table 2. One of the winding wheels 18 is installed on the left side of the sliding table 2. An arc surface 24 for the feeding tape 17 to fit through is formed on the right side of the sliding table 2. The arc surface 24 can prevent the tape 17 from breaking when passing through the sliding table 2. When the tape 17 fits and moves along the bottom of the sliding table 2, it will also slide and fit with the guide cylinder 22, ensuring that the guiding drill hole 23 of the tape 17 and the guide cylinder 22 can be contacted after the drilling tool 20 drills a hole.

[0063] A bottom driving seat 25 is installed at the bottom of the top driving arm 101. The second coil reel 13 is installed on the bottom driving seat 25. One or more of the winding wheels 18 are installed beside the second coil reel 13. The punched tape 17 enters the second coil reel 13 along the remaining winding wheels 18. The second coil reel 13 rotates and winds under the drive of a servo motor. The servo motor can drive the second coil reel 13 to make intermittent rotations, ensuring the utilization rate of the tape 17.

[0064] Further, a first guide wheel 14 and a second guide wheel 15 are installed on the right side of the sliding table 2. The tape 17 passes between the first guide wheel 14 and the second guide wheel 15. A lateral moving member 16 for driving the second guide wheel 15 to approach or move away from the first guide wheel 14 is horizontally arranged on the top driving arm 101; after the tape 17 is unwound, it passes between the first guide wheel 14 and the second guide wheel 15. Driven by the lateral moving member 16, the second guide wheel 15 can approach or move away from the first guide wheel 14. When it is necessary to adjust its friction force, the second guide wheel 15 can be moved to cooperate with the first guide wheel 14 to clamp the tape 17 and prevent it from moving forward.

[0065] Preferably, the lateral moving member 16 is a horizontally arranged telescopic cylinder.

[0066] The punching mechanism includes a bottom driving seat 25 for installing the drilling tool 20. The bottom driving seat 25 is provided with a driving tool seat 26 for installing the drilling tool 20 and a lifting power member 27 for driving the drilling tool 20 to move longitudinally. The lifting power member 27 is a linear module or a lifting cylinder. Driven by the lifting power member 27, the drilling tool 20 can move vertically to drill a hole in the PCB located above.

[0067] Further, the bottom driving seat 25 is also provided with a photographing mechanism. The photographing mechanism includes an X-RAY camera 28. The X-RAY camera 28 is longitudinally installed on the bottom driving seat 25. After the PCB board is placed on the drilling platform, the position to be drilled can be photographed and positioned by the X-RAY camera 28 to determine the drilling position. Since both the X-RAY camera 28 and the drilling tool 20 are installed on the bottom driving seat 25 and the distance between them is a fixed value, after the X-RAY camera 28 determines the drilling position, the position where the drilling tool 20 needs to move can be calculated.

[0068] Subsequently, after the PCB board is positioned by the pressing mechanism, the drilling tool 20 of the drilling device 10 can drill the determined position.

[0069] The drilling device 10 further includes a tool changing mechanism 3. The tool changing mechanism 3 includes a tool changing platform 30. The tool changing platform 30 includes a driving plate 31 and a tool changing disc 32. The driving plate 31 and the tool changing disc 32 can move relative to each other in the Y-axis direction; beside the tool changing platform 30, there is a tool changing manipulator 33 horizontally aligned with the tool changing disc 32. The driving end of the tool changing manipulator 33 is installed with a tool changing module 34 capable of moving in the X and Z axes, and the drilling tool 20 can move in the X and Y axes.

[0070] When a tool change is needed, the driving plate 31 and the tool changing disc 32 can move relative to each other in the Y-axis direction, so that the tool changing disc 32 can be exposed outward from the driving plate 31, making the tool changing disc 32 flush with the tool changing module 34 and the drilling tool 20 in the X-axis direction. The tool changing manipulator 33 replaces the drilling tool 20 with the tool changing module 34 onto the tool changing disc 32; during the replacement, the movement path of the tool changing module 34 is reduced, enabling a quick replacement, improving the replacement efficiency, and meeting the requirements of mass production.

[0071] Preferably, the tool changing module 34 is driven by a linear module arranged in the X-axis direction and a linear module arranged in the Z-axis direction to move in the X and Z axes.

[0072] Preferably, the tool changing platform 30 further includes a tool changing driving seat 33. The driving plate 31 and the tool changing disc 32 are both installed on the tool changing driving seat 33. The tool changing driving seat 33 is provided with a tool disc driving member for driving the tool changing driving seat 33 to move in the Y-axis direction. The tool disc driving member is a horizontal telescopic cylinder 35. When the horizontal telescopic cylinder 35 makes an extending movement, the tool disc support plate 34 remains stationary, and the tool changing disc 32 moves away from the driving plate 31 until the driving plate 31 no longer blocks the tool changing disc 32, enabling the tool changing disc 32 to be exposed until it moves to be aligned with the tool changing module 34 of the tool changing manipulator 33 in the X-axis direction, facilitating a quick tool change.

[0073] The drilling platform 1 is provided with a blanking component 4. The blanking component 4 includes a blanking support arm 41 arranged above the drilling platform 1. The blanking support arm 41 is arranged along the moving direction of the PCB board. A blanking support frame 5 is slidably installed on the blanking support arm 41. The blanking support frame 5 is provided with a suction frame 50 capable of moving longitudinally. The suction frame 50 is installed with a plurality of suction cups 54 for sucking the PCB board.

[0074] Furthermore, the blanking support frame 5 is provided with a lifting cylinder to drive the suction frame 50 to perform a lifting motion.

[0075] The blanking support arm 41 is installed above the drilling platform 1 and does not occupy the space of the drilling platform 1. The remaining mechanical equipment of the drilling platform 1 can be arranged according to requirements. When it is necessary to blank the drilled PCB board, the blanking support frame 5 moves along the blanking support arm 41 until it is longitudinally aligned with the PCB board. Then, the suction frame 50 descends to suck the PCB board through the suction cups 54, and then moves along the blanking support arm 41 to the outside for blanking, ensuring the blanking efficiency without affecting the arrangement of the remaining mechanical mechanisms of the drilling equipment.

[0076] Furthermore, the blanking component 4 further includes a blanking transmission member for driving the blanking support frame 5 to move along the length direction of the blanking support arm 41. The blanking transmission member includes a belt transmission member 44 arranged parallel to the blanking support arm 41. One of the long sides of the belt transmission member 44 is installed with a transmission seat 48 along the way. The transmission seat 48 is connected to the blanking support frame 5. Driven by the belt transmission member 44, the transmission seat 48 can reciprocally move along the blanking direction of the PCB board. Since the transmission seat 48 is connected to the blanking support frame 5, it can drive the blanking support frame 5 to move along the length direction of the blanking support arm 41 to achieve the blanking of the PCB board.

[0077] Preferably, the belt transmission member 44 further includes transmission support seats 45 installed at both ends of the blanking support arm 41. The transmission support seats 45 are installed with belt transmission wheels 46. A transmission belt 47 is nested between the two belt transmission wheels 46. The belt transmission wheels 46 are in transmission connection with the transmission belt 47. One of the belt transmission wheels 46 is a driving wheel and can rotate forward and backward under the drive of a forward and reverse motor. When the forward and reverse motor rotates forward, the transmission seat 48 can move along the forward direction of the blanking of the PCB board. When the forward and reverse motor rotates backward, the transmission seat 48 can move backward along the blanking direction of the PCB board to reciprocally blank the PCB board.

[0078] Furthermore, a support guide rail 42 is arranged along the length direction of the blanking support arm 41. A support sliding seat 43 is slidably installed on the support guide rail 42. The blanking support frame 5 is connected to the support sliding seat 43. Through the sliding fit between the support guide rail 42 and the support sliding seat 43, the linear movement stability of the blanking support frame 5 can be further improved, and the stability of the PCB board blanking can be improved.

[0079] Preferably, the number of the blanking support arms 41 is two, and they are arranged in parallel at intervals. The support guide rail 42 is installed at the bottom of the blanking support arms 41. The top of the blanking support frame 5 is connected to the support sliding seat 43, so that the blanking support frame 5 moves at the bottom of the blanking support arms 41.

[0080] Specific structure of the adsorption frame 50: The adsorption frame 50 includes an adsorption plate 51 and a plurality of adsorption strips 22 arranged on the adsorption plate 51. One end of the adsorption strip 22 extends outward from the adsorption plate 51. The suction cups 54 are respectively installed on the adsorption strips 22 and the adsorption plate 51. The plurality of suction cups 54 are arranged on the adsorption plate 51 and the adsorption strips 22 of the adsorption frame 50. When contacting the PCB board, the adsorption area can be increased, and the stability of the adsorption of the PCB board is further increased. After being lifted, it is not easy to fall off and will not tilt, ensuring that the PCB board is smoothly blanked from the drilling platform 1.

[0081] Preferably, the adsorption plate 51 is formed with a plurality of first installation long grooves 55, and the adsorption strip 22 is formed with a plurality of second installation long grooves 56 along the length direction. The first installation long grooves 55 and the second installation long grooves 56 are both slidably installed with sliding installation blocks 53. The suction cups 54 are respectively installed on the first installation long grooves 55 and the second installation long grooves 56 through the sliding installation blocks 53. The sliding installation blocks 53 can move along the corresponding first installation long grooves 55 and second installation long grooves 56, so that the positions of the sliding installation blocks 53 change, that is, the suction cups 54 installed on the sliding installation blocks 53 can change positions. According to the drilling positions of the PCB board, the contact positions of the suction cups 54 with the PCB board can be adjusted to prevent air suction, ensure that a plurality of suction cups 54 are all adsorbed to the PCB board, and ensure the stability of adsorption.

[0082] Preferably, the adsorption plate 51 is further formed with installation holes 57 for installing the adsorption strips 22. One end of the adsorption strip 22 is formed with an installation column 58 that is rotationally matched with the installation holes 57. The adsorption plate 51 is provided with a blanking adjustment member 59 that is tightly connected to the installation column 58. Through the rotational matching of the installation column 58 with the installation holes 57 of the adsorption plate 51, the adsorption strip 22 can swing and adjust the angle, that is, the positions of the suction cups 54 will change, further increasing the diversity of the position adjustment of the suction cups 54. After adjusting to the required position, the installation column 58 can be locked with the adsorption plate 51 through the blanking adjustment member 59 to prevent loosening.

[0083] Preferably, the installation column 58 is formed with an external thread structure, and the blanking adjustment member 59 can be a threaded sleeve handle. By twisting the threaded sleeve handle, the tightness between the installation column 58 and the adsorption plate 51 can be adjusted.

[0084] The drilling platform 1 is also provided with a pushing plate mechanism 65 arranged along the advancing direction of the PCB board. The pushing plate mechanism 65 includes a drilling positioning plate 67 for supporting the PCB board. The drilling positioning plate 67 can reciprocate along the advancing direction of the PCB board. Initially, the PCB board is first placed into the drilling positioning plate 67. The drilling positioning plate 67 moves along the advancing direction of the PCB board to be coaxially aligned with the drilling tool 20 at the drilling position. Subsequently, after the PCB board is positioned by the pressing mechanism, the drilling tool 20 of the drilling device 17 can drill holes at the determined position.

[0085] After the drilling is completed, the pressing mechanism retracts. The drilling positioning plate 67 continues to move along the advancing direction of the PCB board to the waiting-for-unloading station. The unloading support frame 5 of the unloading assembly 4 moves along the unloading support arm 41 to the waiting-for-unloading station and is longitudinally aligned with the drilled PCB board. The adsorption frame 50 moves longitudinally, and the PCB board is adsorbed by a plurality of suction cups 54. The unloading support frame 5 moves along the unloading support arm 41 in a direction away from the waiting-for-unloading station to achieve unloading.

[0086] Preferably, the pushing plate mechanism 65 further includes a pushing linear module 66. The drilling positioning plate 67 is installed at the driving end of the pushing linear module 66, and the pushing linear module 66 drives the drilling positioning plate 67 to reciprocate along the advancing direction of the PCB board.

[0087] The drilling working plate 61 is provided with a drilling guiding groove 62 for the drilling tool 20 of the drilling device 10 to pass through. Above the drilling working plate 61, there is a pressing mechanism for positioning the PCB board. The pressing mechanism includes a pair of pressing seats 63 arranged at intervals. The pressing seats 63 are installed with longitudinally arranged pressing blocks 64. The pressing blocks 64 can longitudinally move to press the PCB board on the drilling working plate 61.

[0088] Preferably, the pressing seat 63 is installed with a lifting cylinder. The driving end of the lifting cylinder is connected to the pressing block 64. When the PCB board moves to the drilling working plate 61 in place, the lifting cylinder drives the pressing block 64 to press down to prevent the PCB board from shifting laterally.

[0089] The drilling working plate 61 is formed with a guiding through groove 68 for the guiding and sliding of the drilling positioning plate 67 along the length direction. The drilling working plate 61 shields a part of the pushing linear module 66. The guiding through groove 68 can guide the movement of the drilling positioning plate 67 to prevent the drilling positioning plate 67 from being knocked or collided.
