DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0036] Embodiment one

[0037] In the process of drilling the PCB, due to the relatively low hardness and rigidity of the PCB, the cutting force of the drill bit 35 is easy to cause the deformation of the PCB, especially the thin-walled or soft PCB, which is more prone to collapse, which will affect the overall appearance defect and reduce the dimensional accuracy.

[0038] As shown in Figures 1 to 8 , the PCB manufacturing equipment described in the embodiment of the present application comprises a workbench 1, and the top end of the workbench 1 is provided with a moving mechanism 2, and the moving mechanism 2 is provided with a drilling mechanism 3.

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

[0040] As shown in Figures 1 to 8As shown, the drilling mechanism 3 comprises a mounting box 31, the top of the mounting box 31 is fixedly connected with a cylinder 32, the inside of the mounting box 31 is slidably connected with a motor 33 fixedly connected with the output end of the cylinder 32, the output end of the motor 33 is fixedly connected with a transmission shaft 34, the transmission shaft 34 is slidably connected in the inside of the mounting box 31 and can rotate, the end of the transmission shaft 34 away from the motor 33 is provided with a drill bit 35, and the drill bit 35 is used for drilling the PCB board.

[0041] As shown, Figures 4 to 8 It also comprises an adjusting mechanism 4, the adjusting mechanism 4 is arranged on the drilling mechanism 3, is used for adjusting the drilling depth of the drilling mechanism 3 to the PCB board according to the thickness of the PCB board, the adjusting mechanism 4 comprises a rotating block 41 fixedly connected with the end of the transmission shaft 34 away from the motor 33, the end of the rotating block 41 away from the transmission shaft 34 is provided with a sliding groove 42, the drill bit 35 is slidably connected in the inside of the sliding groove 42, and the end of the drill bit 35 located in the inside of the sliding groove 42 is connected with a first elastic element 43 between 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 in the sliding groove 42, so that the rotating block 41 drives the drill bit 35 to rotate when rotating.

[0043] As shown, Figure 6 The end of the rotating block 41 away from the transmission shaft 34 is rotatably connected with an extension cover 44, the end of the extension cover 44 away from the rotating block 41 is provided with an extension groove 45, the inside of the extension groove 45 is slidably connected with a fixed cover 46, the end of the fixed cover 46 located in the inside of the extension groove 45 is connected with a second elastic element 47 between the extension groove 45, the outer wall of the rotating block 41 is rotatably connected with a sealing sleeve 48, the sliding groove 42 and the sealing sleeve 48 are provided with a communication hole 49, the outer wall of the sealing sleeve 48 is provided with an air inlet hole 410 arranged in a penetrating manner, the outer wall of the extension cover 44 is provided with an air outlet hole 411 in communication with the inside of the extension groove 45, and 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 sleeve 48 are in a rotating connection relationship, the rotating block 41 does not forcibly drive the sealing sleeve 48 to rotate when rotating, and since the rotating block 41 and the extension cover 44 are in a rotating connection relationship, the rotating block 41 does not forcibly drive the sealing sleeve 48 to rotate when rotating, so that the normal rotation of the rotating block 41 is not affected.

[0045] In actual use, first, the PCB board is placed on the workbench 1, the position of the drilling mechanism 3 in the Y direction is adjusted through the first lead screw module 21, the position of the drilling mechanism 3 in the X direction is adjusted through the second lead screw module 22, and the drilling mechanism 3 corresponds to the drilling position of the PCB board.

[0046] When the drilling mechanism 3 corresponds to the PCB drilling position, the control cylinder 32 drives the motor 33 to slide down, and the motor 33 slides down to drive the adjusting mechanism 4 to move down, so that the adjusting mechanism 4 is tightly pressed on the PCB for positioning.

[0047] When the adjusting mechanism 4 is pressed on the PCB, the fixed cover 46 slides up in the telescopic groove 45 to extrude the second elastic member 47, so that the fixed cover 46 extrudes the air in the telescopic groove 45 into the sealing sleeve 48 through the first transmission pipe 412, and then into the sliding groove 42 through the communication hole 49. The air in the sliding groove 42 pushes the drill bit 35 to move down, and at the same time, stretches the first elastic member 43, so as to drill the PCB. Since the stroke of the cylinder 32 is unchanged, when the thickness of the PCB is thicker, the distance of the fixed cover 46 sliding up in the telescopic groove 45 is greater, the air extruded by the fixed cover 46 into the sliding groove 42 from the telescopic groove 45 is more, and the distance of the drill bit 35 moving down is greater, and vice versa, so that the drill bit 35 can adaptively adjust the drilling depth according to the thickness of the PCB.

[0048] After the drilling is completed, the control cylinder 32 drives the motor 33 to slide up, and the motor 33 slides up to drive the adjusting mechanism 4 to move up, so that the adjusting mechanism 4 is away from the PCB. Since the fixed cover 46 is in contact with the PCB after the adjusting mechanism 4 moves up, the second elastic member 47 pushes the fixed cover 46 to move down and return to the initial position. In the process of the fixed cover 46 returning to the initial position, the air in the sliding groove 42 is sucked back into the telescopic groove 45 through the first transmission pipe 412, so that the drill bit 35 compresses the first elastic member 43 to return to the initial position, preparing for the next drilling.

[0049] In summary, through the setting of the adjusting mechanism 4, when the drilling mechanism 3 drills the PCB, the fixed cover 46 slides up in the telescopic groove 45, so that the air in the telescopic groove 45 enters the sliding groove 42, and the air in the sliding groove 42 pushes the drill bit 35 to move down, so as to drill the PCB. Since the stroke of the cylinder 32 is unchanged, when the thickness of the PCB is thicker, the distance of the fixed cover 46 sliding up in the telescopic groove 45 is greater, the air extruded by the fixed cover 46 into the sliding groove 42 from the telescopic groove 45 is more, and the distance of the drill bit 35 moving down is greater, and vice versa, so that the drill bit 35 can adaptively adjust the drilling depth according to the thickness of the PCB. It can ensure that the drilling depth matches the thickness of the PCB, thereby avoiding errors caused by improper manual setting. At the same time, automatic depth adjustment can reduce the time of manual adjustment, thereby improving the production efficiency.

[0050] Embodiment Two

[0051] In actual use, some PCBs have high elasticity, and the material cannot recover in time due to elastic deformation during drilling, resulting in collapse. The heat generated by the drill bit 35 during drilling also causes the PCB to deform and cannot recover after cooling. Therefore, the device described in the above embodiment is improved in this embodiment.

[0052] As shown in Figures 1 to 8 , it further comprises a fixing mechanism 5 arranged on the drilling mechanism 3 for fixing the PCB in cooperation with the drilling mechanism 3 and the adjusting mechanism 4.

[0053] As shown in Figures 3 to 6 , the fixing mechanism 5 comprises a piston cylinder 51 fixedly connected to the top of the mounting box 31, a piston 52 slidingly installed in the interior of the piston cylinder 51, a transmission cylinder 53 fixedly connected to the bottom of the piston 52, a rotating groove 54 formed in the interior of the mounting box 31, and a lifting groove 55 formed in the interior of the mounting box 31 between the piston cylinder 51 and the rotating groove 54. The transmission cylinder 53 is slidingly connected in the interior of the lifting groove 55, and a threaded lead screw 516 is threadedly connected in the interior of the transmission cylinder 53. The end of the threaded lead screw 516 away from the piston 52 is rotatably connected in the interior of the rotating groove 54.

[0054] As shown in Figure 4 , a first gear 56 and a second gear 57 are fixedly connected to the outer wall of the threaded lead screw 516 in the interior of the rotating groove 54, and a drive gear 58 is fixedly connected to the outer wall of the transmission shaft 34 in the interior of the rotating groove 54. The drive gear 58 can engage with the first gear 56 and the second gear 57. When the output end of the air cylinder 32 is fully extended, the drive gear 58 engages with the first gear 56. When the output end of the air cylinder 32 is fully retracted, the drive gear 58 engages with the second gear 57.

[0055] As shown in Figures 4 to 6 , a shunt cavity 59 is formed in the interior of the telescopic cover 44, an air suction groove 510 is formed in the bottom of the telescopic cover 44, a plurality of shunt holes 511 are uniformly formed between the shunt cavity 59 and the air suction groove 510, a first exhaust hole 512 is formed in the outer wall of the telescopic cover 44 and communicates with the interior of the shunt cavity 59, a second exhaust hole 513 and a third exhaust hole 514 are formed in the outer wall of the piston cylinder 51, and the first exhaust hole 512 and the second exhaust hole 513 communicate through a second transmission pipe 515.

[0056] As shown in Figures 3 to 6 , when the piston 52 moves upward in the piston cylinder 51, the gas in the air suction groove 510 can be drawn into the piston cylinder 51 through the second transmission pipe 515. When the piston 52 moves downward in 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 PCB drilling position, the control cylinder 32 drives the motor 33 to slide down, the motor 33 slides down to drive the driving gear 58 fixedly connected to the outer wall of the transmission shaft 34 to slide in the rotating groove 54, when the output end of the cylinder 32 is completely extended, the control motor 33 drives the transmission shaft 34 to rotate forward, and the PCB is drilled, at this time, the driving gear 58 on the transmission shaft 34 will mesh with the first gear 56 on the threaded rod 516 to rotate clockwise, however, the threaded rod 516 is threadedly connected with the transmission cylinder 53, when the first gear 56 rotates clockwise, the threaded rod 516 is driven to rotate, so that the transmission cylinder 53 drives the piston 52 to move upward in the piston cylinder 51, in the process of moving upward in the piston cylinder 51, the piston 52 drives the air in the air suction groove 510 and the shunt cavity 59 to enter the second transmission pipe 515 through the shunt hole 511 and the first exhaust hole 512, and then the air is sucked into the piston cylinder 51 through the second transmission pipe 515, so that the negative pressure is generated in the air suction groove 510, thereby adsorbing the position of the PCB to be punched, preventing the position of the PCB to be punched from collapsing in the punching process of the drill bit 35.

[0058] When the drilling is completed, the control cylinder 32 drives the motor 33 to slide up, the motor 33 slides up to drive the driving gear 58 fixedly connected to the outer wall of the transmission shaft 34 to slide in the rotating groove 54, when the output end of the cylinder 32 is completely retracted, the control motor 33 drives the transmission shaft 34 to reverse, the driving gear 58 on the transmission shaft 34 will mesh with the second gear 57 on the threaded rod 516 to rotate counterclockwise, when the second gear 57 rotates counterclockwise, the threaded rod 516 is driven to rotate, so that the transmission cylinder 53 drives the piston 52 to move downward in the piston cylinder 51, in the process of moving downward in the piston cylinder 51, the piston 52 drives the air in the piston cylinder 51 to be discharged into the shunt cavity 59 through the second exhaust hole 513 and the second transmission pipe 515, and then is discharged into the air suction groove 510 through the shunt hole 511 in the shunt cavity 59, and then the drillings on the PCB after drilling are blown away.

[0059] In summary, by the arrangement of the fixing mechanism 5, on the one hand, when the output end of the air cylinder 32 is fully extended and the PCB is drilled, the piston 52 moves upward in the piston cylinder 51 and sucks the air in the air suction groove 510 into the piston cylinder 51, thereby generating negative pressure in the air suction groove 510, so as to adsorb the position of the PCB to be drilled, prevent the position of the PCB to be drilled from collapsing during drilling by the drill bit 35, and prevent the PCB from moving due to vibration during drilling, thereby ensuring the accuracy of the drilling position. On the other hand, when the drilling is completed and the output end of the air cylinder 32 is fully retracted, the piston 52 moves downward in the piston cylinder 51 and discharges the air in the piston cylinder 51 into the air suction groove 510, thereby blowing away the waste on the PCB after drilling, so as to save the time for manual cleaning and improve the production efficiency.
