[0003] Chinese Patent with Application No. CN202410347896.4 discloses a PCB circuit board and its processing equipment, including a drilling component. The drilling component includes a socket block, a second electric telescopic rod, and a drill bit. The second electric telescopic rod is fixedly connected to the socket block. The socket block has a slot for the top end of the drill bit to be vertically inserted. A positioning hole for the telescopic end of the second electric telescopic rod to be embedded is provided on the surface of the drill bit.

A frame is installed on one side of the chassis. A top cover is installed on the surface of the frame. A horizontal movement component is provided at the bottom of the top cover. The purpose of this invention is to solve the problem that during the drilling process of the processing equipment on the substrate, heat is generated, which easily makes the PCB circuit board soft, resulting in a reduction in the mechanical strength of the PCB circuit board and being unfavorable for mechanical processing.

[0004] Although the above invention conveniently solves the problem that during the drilling process of the processing equipment on the substrate, heat is generated, which easily makes the PCB circuit board soft, resulting in a reduction in the mechanical strength of the PCB circuit board and being unfavorable for mechanical processing, the hardness and rigidity of the PCB board are relatively low. During drilling, the cutting force of the drill bit easily causes the PCB board to deform. Especially for thin-walled or softer PCB boards, it is more likely to collapse, which will affect its overall appearance defects and reduce dimensional accuracy. And some PCB boards have high elasticity. During drilling, the material cannot recover to its original state in time due to elastic deformation, resulting in collapse.

Since the stroke of the cylinder is constant, when the thickness of the PCB board is thicker, the upward distance of the fixed cover in the telescopic groove will be more.

On the other hand, when the drilling is completed and the output end of the cylinder is controlled to fully retract, the piston moves downward inside the piston cylinder, discharging the air inside the piston cylinder into the suction groove, and then blowing the waste chips on the PCB board after drilling, which can save the time of manual cleaning and improve production efficiency.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] Example 1

[0037] During the drilling process of the PCB board, due to the relatively low hardness and rigidity of the PCB board, the cutting force of the drill bit 35 during drilling can easily cause the PCB board to deform, especially thin-walled or soft PCB boards, which are more likely to collapse, affecting their overall appearance and reducing dimensional accuracy.

[0038] like Figures 1 to 8 As shown, a PCB board manufacturing device according to an embodiment of the present invention includes a workbench 1, a moving mechanism 2 is provided on the top of the workbench 1, and a drilling mechanism 3 is provided on the moving mechanism 2.

[0039] like Figure 1 and Figure 2 As shown, the moving mechanism 2 includes a first screw module 21 for adjusting the Y-direction movement of the drilling mechanism 3. The first screw module 21 is installed with a second screw module 22 for adjusting the X-direction movement of the drilling mechanism 3. The drilling mechanism 3 is installed on the second screw module 22.

[0040] like Figures 1 to 8As shown in the figure, the drilling mechanism 3 includes an installation box 31. A cylinder 32 is fixedly connected to the top of the installation box 31. A motor 33 fixedly connected to the output end of the cylinder 32 is slidably connected inside the installation box 31. A transmission shaft 34 is fixedly connected to the output end of the motor 33. The transmission shaft 34 is slidably connected inside the installation box 31 and can rotate. A drill bit 35 is provided at one end of the transmission shaft 34 away from the motor 33. The drill bit 35 is used for drilling the PCB board.

[0041] As Figures 4 to 8 shown in the figure, it further includes an adjustment mechanism 4. The adjustment mechanism 4 is arranged on the drilling mechanism 3 and is used to adjust the drilling depth of the drilling mechanism 3 for the PCB board according to the thickness of the PCB board. The adjustment mechanism 4 includes a rotating block 41 fixedly connected to one end of the transmission shaft 34 away from the motor 33. A sliding groove 42 is opened at one end of the rotating block 41 away from the transmission shaft 34. The drill bit 35 is slidably connected inside the sliding groove 42. A first elastic member 43 is connected between one end of the drill bit 35 located inside the sliding groove 42 and the sliding groove 42.

[0042] Since the drill bit 35 and the sliding groove 42 are in a sliding connection relationship, the drill bit 35 can only slide inside the sliding groove 42. Therefore, when the rotating block 41 rotates, it will drive the drill bit 35 to rotate.

[0043] As Figure 6 shown in the figure, a telescopic cover 44 is rotatably connected to one end of the rotating block 41 away from the transmission shaft 34. A telescopic groove 45 is opened at one end of the telescopic cover 44 away from the rotating block 41. A fixed cover 46 is slidably connected inside the telescopic groove 45. A second elastic member 47 is connected between one end of the fixed cover 46 located inside the telescopic groove 45 and the telescopic groove 45. A sealing rotating sleeve 48 is rotatably connected to the outer wall of the rotating block 41. A communication hole 49 is opened between the sliding groove 42 and the sealing rotating sleeve 48. An air inlet hole 410 is opened in a penetrating manner on the outer wall of the sealing rotating sleeve 48. An air outlet hole 411 communicating with the inside of the telescopic groove 45 is opened on the outer wall of the telescopic cover 44. The air outlet hole 411 and the air inlet hole 410 are communicated through a first transmission pipe 412.

[0044] Since the rotating block 41 and the sealing rotating sleeve 48 are in a rotating connection relationship, when the rotating block 41 rotates, it will not forcibly drive the sealing rotating sleeve 48 to rotate. At the same time, since the rotating block 41 and the telescopic cover 44 are in a rotating connection relationship, when the rotating block 41 rotates, it will not forcibly drive the sealing rotating sleeve 48 to rotate either, thus not affecting the normal rotation of the rotating block 41.

[0045] During actual use, first place the PCB board on the workbench 1. Adjust the position of the drilling mechanism 3 in the Y direction through the first lead screw module 21, and adjust the position of the drilling mechanism 3 in the X direction through the second lead screw module 22, so that the drilling mechanism 3 corresponds to the drilling position of the PCB board.

[0046] After the drilling mechanism 3 corresponds to the drilling position of the PCB board, control the air cylinder 32 to drive the motor 33 to slide downward. The downward sliding of the motor 33 will drive the adjusting mechanism 4 to move downward through the transmission shaft 34, so that the adjusting mechanism 4 presses tightly on the PCB board for positioning.

[0047] When the adjusting mechanism 4 presses on the PCB board, it will cause the fixed cover 46 to slide upward in the telescopic groove 45, squeezing the second elastic member 47, so that the fixed cover 46 squeezes the air in the telescopic groove 45 into the sealing rotating sleeve 48 through the first transmission pipe 412, and then enters the sliding groove 42 through the communication hole 49. The air entering the sliding groove 42 will push the drill bit 35 downward, and at the same time stretch the first elastic member 43, thereby drilling the PCB board. Since the stroke of the air cylinder 32 is constant, when the thickness of the PCB board is thicker, the upward distance of the fixed cover 46 in the telescopic groove 45 will be more, and the more air in the telescopic groove 45 is squeezed into the sliding groove 42 by the fixed cover 46, the more the drill bit 35 moves downward, and vice versa, the less the downward movement distance, so that the drill bit 35 can adaptively adjust the drilling depth according to the thickness of the PCB board.

[0048] After drilling is completed, control the air cylinder 32 to drive the motor 33 to slide upward. The upward sliding of the motor 33 will drive the adjusting mechanism 4 to move upward through the transmission shaft 34, so that the adjusting mechanism 4 moves away from the PCB board. Since the fixed cover 46 will continue to contact the PCB board after the adjusting mechanism 4 moves upward, at this time the second elastic member 47 will push the fixed cover 46 to move downward and return to the initial position. During the process of the fixed cover 46 returning to the initial position, it will re-pump the air in the sliding groove 42 back into the telescopic groove 45 through the first transmission pipe 412, so that the drill bit 35 compresses the first elastic member 43 and returns to the initial position to prepare for the next drilling.

[0049] In summary, through the setting of the adjusting mechanism 4, when the drilling mechanism 3 drills the PCB board, it will cause the fixed cover 46 to slide upward in the telescopic groove 45, so that the air in the telescopic groove 45 enters the sliding groove 42, and the air inside the sliding groove 42 pushes the drill bit 35 downward, thereby drilling the PCB board. Since the stroke of the air cylinder 32 is constant, when the thickness of the PCB board is thicker, the upward distance of the fixed cover 46 in the telescopic groove 45 will be more, and the more air in the telescopic groove 45 is squeezed into the sliding groove 42 by the fixed cover 46, the more the drill bit 35 moves downward, and vice versa, the less the downward movement distance, so that the drill bit 35 can adaptively adjust the drilling depth according to the thickness of the PCB board, which can ensure that the drilling depth matches the thickness of the PCB board, thereby avoiding errors caused by improper manual setting. At the same time, the automatic adjustment of the depth can reduce the time of manual adjustment, thereby improving production efficiency.

[0050] Example 2

[0051] During actual use, since some PCB boards have high elasticity, the material will not be able to return to its original state in time due to elastic deformation during drilling, resulting in collapse. In addition, the heat generated by the drill bit 35 during drilling will also cause the PCB board to deform and not be able to recover after cooling. Therefore, the device described in the above embodiment is improved in this embodiment.

[0052] As Figures 1 to 8 shown, it further includes a fixing mechanism 5. The fixing mechanism 5 is arranged on the drilling mechanism 3 and is used to cooperate with the drilling mechanism 3 and the adjusting mechanism 4 to fix the PCB board.

[0053] As Figures 3 to 6 shown, the fixing mechanism 5 includes a piston cylinder 51 fixedly connected to the top of the installation box 31. A piston 52 is slidably installed inside the piston cylinder 51. The bottom of the piston 52 is fixedly connected to a transmission cylinder 53. A rotating groove 54 is opened inside the installation box 31. A lifting groove 55 is opened inside the installation box 31 between the piston cylinder 51 and the rotating groove 54. The transmission cylinder 53 is slidably connected inside the lifting groove 55. A threaded lead screw 516 is threadedly connected inside the transmission cylinder 53. One end of the threaded lead screw 516 away from the piston 52 is rotatably connected inside the rotating groove 54.

[0054] As Figure 4 shown, a first gear 56 and a second gear 57 are fixedly connected to the outer wall of the threaded lead screw 516 inside the rotating groove 54. A driving gear 58 is fixedly connected to the outer wall of the transmission shaft 34 inside the rotating groove 54. The driving gear 58 can mesh with the first gear 56 and the second gear 57. When the output end of the air cylinder 32 fully extends, the driving gear 58 meshes with the first gear 56. When the output end of the air cylinder 32 fully retracts, the driving gear 58 meshes with the second gear 57.

[0055] As Figures 4 to 6 shown, a shunt cavity 59 is opened inside the telescopic cover 44. An air suction groove 510 is opened at the bottom of the telescopic cover 44. A plurality of shunt holes 511 are evenly opened between the shunt cavity 59 and the air suction groove 510. A first exhaust hole 512 communicating with the inside of the shunt cavity 59 is opened on the outer wall of the telescopic cover 44. A second exhaust hole 513 and a third exhaust hole 514 are opened on the outer wall of the piston cylinder 51. The first exhaust hole 512 and the second exhaust hole 513 are communicated through a second transmission pipe 515.

[0056] As Figures 3 to 6 shown, when the piston 52 moves upward inside the piston cylinder 51, the gas in the air suction groove 510 can be pumped into the piston cylinder 51 through the second transmission pipe 515. When the piston 52 moves downward inside the piston cylinder 51, the gas in the piston cylinder 51 can be discharged into the air suction groove 510 through the second transmission pipe 515.

[0057] When the drilling mechanism 3 corresponds to the drilling position of the PCB board, control the air cylinder 32 to drive the motor 33 to slide downward. The downward sliding of the motor 33 will drive the driving gear 58 fixedly connected to the outer wall of the transmission shaft 34 to slide inside the rotating groove 54. When the output end of the air cylinder 32 fully extends, control the motor 33 to drive the transmission shaft 34 and the drill bit 35 to rotate forward to drill the PCB board. At this time, the driving gear 58 on the transmission shaft 34 will engage with the first gear 56 on the threaded screw rod 516 to rotate clockwise. However, the threaded screw rod 516 is threadedly connected to the transmission cylinder 53. When the first gear 56 rotates clockwise, it will drive the threaded screw rod 516 to rotate, so that the transmission cylinder 53 drives the piston 52 to move upward inside the piston cylinder 51. During the upward movement of the piston 52 inside the piston cylinder 51, the air in the suction groove 510 and the diversion chamber 59 will enter the second transmission pipe 515 through the diversion holes 511 and the first exhaust holes 512, and then the air will be sucked into the piston cylinder 51 through the second transmission pipe 515, thereby generating a negative pressure in the suction groove 510, so as to adsorb the position of the PCB board that needs to be drilled, preventing the position of the PCB board from collapsing during the drilling process by the drill bit 35.

[0058] After the drilling is completed, control the air cylinder 32 to drive the motor 33 to slide upward. The upward sliding of the motor 33 will drive the driving gear 58 fixedly connected to the outer wall of the transmission shaft 34 to slide inside the rotating groove 54. When the output end of the air cylinder 32 fully retracts, control the motor 33 to drive the transmission shaft 34 and the drill bit 35 to rotate reversely. The driving gear 58 on the transmission shaft 34 will engage with the second gear 57 on the threaded screw rod 516 to rotate counterclockwise. When the second gear 57 rotates counterclockwise, it will drive the threaded screw rod 516 to rotate, so that the transmission cylinder 53 drives the piston 52 to move downward inside the piston cylinder 51. During the downward movement of the piston 52 inside the piston cylinder 51, the air inside the piston cylinder 51 will be discharged into the diversion chamber 59 through the second exhaust holes 513 and the second transmission pipe 515, and then discharged into the suction groove 510 through the diversion holes 511 in the diversion chamber 59, thereby blowing away the waste chips on the PCB board after drilling.

[0059] In summary, through the setting of the fixing mechanism 5, on the one hand, when drilling the PCB board when the output end of the cylinder 32 is fully extended, the piston 52 will move upward inside the piston cylinder 51, and suck the air in the air suction groove 510 into the inside of the piston cylinder 51, thereby generating a negative pressure in the air suction groove 510, so as to adsorb the position of the PCB board to be drilled, prevent the position of the PCB board to be drilled from collapsing during the drilling process by the drill bit 35, and also prevent it from moving due to vibration during the drilling process, thus ensuring the accuracy of the drilling position. On the other hand, when the drilling is completed and the output end of the control cylinder 32 is fully retracted, the piston 52 moves downward inside the piston cylinder 51, discharges the air inside the piston cylinder 51 into the air suction groove 510, and then blows off the waste chips on the PCB board after drilling, thereby saving the time of manual cleaning and improving the production efficiency.
