Description

Technical Field

[0001] The utility model belongs to the technical field of drilling equipment, and in particular relates to a fast positioning drilling device for PCB circuit board production. Background Art

[0002] PCB circuit board, or printed circuit board for short, is one of the important components of the electronics industry. Almost every electronic device, from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use circuit boards to make electrical interconnections between the various components. Before installing components on the PCB circuit board, holes must be drilled on the board so that the pins of the components can be inserted or the circuits on different levels can be connected up and down. Therefore, workers need to use drilling devices when producing circuit boards.

[0003] However, there are some problems with the prior art: although the existing drilling device can clamp and position the circuit board to ensure stability during drilling, in actual use, workers often need to drill holes of different sizes on the circuit board so as to subsequently install different types of plug-in components on the circuit board. However, the existing drilling device is usually only equipped with one set of drilling rigs, so the workers may need to frequently disassemble and replace the drill bits on the drilling rigs to drill holes of different sizes, which reduces the production efficiency of the circuit board. Therefore, we propose a fast positioning drilling device for PCB circuit board production. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a fast positioning drilling device for PCB circuit board production, which can improve the production efficiency of circuit boards by facilitating the adjustment of different drill bits for drilling holes in the circuit boards.

[0005] The utility model is implemented as follows: a fast positioning drilling device for PCB circuit board production comprises a base, a first guide rail is fixedly installed on the base, an electric slide is slidably connected to the first guide rail, a vertical plate is arranged on the electric slide, the vertical plate and the electric slide are connected by a driving mechanism, a brake motor is fixedly installed on the vertical plate, the output shaft of the brake motor is fixedly sleeved with a rotating shaft, the other end of the rotating shaft is fixedly connected with a disc, a notch is opened on the disc, a drill is arranged at the bottom of the disc, a drill bit is fixedly sleeved on the output shaft of the drill, the drill and the disc are connected by a reset mechanism, a first electric push rod is also fixedly installed on the vertical plate for driving the drill bit to descend to drill holes in the circuit board, and a clamping mechanism is arranged on the base for positioning the circuit board.

[0006] Optionally, the resetting mechanism comprises a guide rod, the guide rod is fixedly mounted on the disc, a frame is movably sleeved on the outer surface of the guide rod, and the drilling rig is fixedly mounted on the frame.

[0007] Optionally, a spring is movably sleeved on the outer surface of the guide rod, and two ends of the spring are respectively fixedly connected to the surfaces of the disc and the frame.

[0008] Optionally, the driving mechanism includes a second guide rail, the second guide rail is fixedly mounted on the electric slide, a driving motor is fixedly mounted on the second guide rail, a screw rod is fixedly sleeved on the output shaft of the driving motor, and the vertical plate is threadedly connected to the outer surface of the screw rod.

[0009] Optionally, a through hole is formed on the base, and the clamping mechanism comprises a clamp, a connecting block located in the through hole is fixedly connected to the clamp, and a round block is fixedly connected to the bottom of the connecting block.

[0010] Optionally, a second electric push rod is fixedly installed at the bottom of the base, and a push-pull plate is fixedly connected to the telescopic end of the second electric push rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a brake motor, a rotating shaft, a disc, a drilling rig and a drill bit.

Subsequently, starting the first electric push rod can move the drill bit downward to drill holes in the circuit board, thereby eliminating the need for workers to disassemble and replace the drill bit, thereby improving the production efficiency of the circuit board.

DETAILED DESCRIPTION

[0021] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, a fast positioning drilling device for PCB circuit board production provided by an embodiment of the utility model includes a base 1, a first guide rail 2 is fixedly installed on the base 1, an electric slide 3 is slidably connected to the first guide rail 2, a vertical plate 4 is arranged on the electric slide 3, the vertical plate 4 and the electric slide 3 are connected by a driving mechanism, a brake motor 5 is fixedly installed on the vertical plate 4, the output shaft of the brake motor 5 is fixedly sleeved with a rotating shaft 6, the other end of the rotating shaft 6 is fixedly connected with a disc 7, a notch 8 is opened on the disc 7, a drill rig 9 is arranged at the bottom of the disc 7, a drill bit 10 is fixedly sleeved on the output shaft of the drill rig 9, the drill rig 9 and the disc 7 are connected by a reset mechanism, a first electric push rod 11 is also fixedly installed on the vertical plate 4 for driving the drill bit 10 to descend to drill holes in the circuit board, and a clamping mechanism is arranged on the base 1 for positioning the circuit board.

[0023] By providing a plurality of sets of drills 9 and drill bits 10, and each set of drill bits 10 has a different size, holes of different sizes can be drilled on the circuit board, and the staff can start the brake motor 5 to make the rotating shaft 6 drive the disc 7 to rotate, so that the drill 9 required for drilling can be rotated to the bottom of the first electric push rod 11, and then the first electric push rod 11 is started to make the drill bit 10 descend to drill the circuit board, without the need for the staff to disassemble and replace the drill bit 10, which is more convenient to use.

[0024] Furthermore, the reset mechanism includes a guide rod 12 , which is fixedly mounted on the disc 7 , and a frame 13 is movably sleeved on the outer surface of the guide rod 12 , and the drilling rig 9 is fixedly mounted on the frame 13 .

[0025] Furthermore, a spring 14 is movably sleeved on the outer surface of the guide rod 12 , and two ends of the spring 14 are fixedly connected to the surfaces of the disc 7 and the frame 13 , respectively.

[0026] By setting the spring 14 to a compressed state, the frame 13 will tend to move upward due to the elastic recovery effect of the spring 14, so that when the frame 13 is not pushed by the first electric push rod 11, it will be stretched back to its original position by the spring 14, thereby not affecting the drilling of the circuit board by the drill 9 and the drill bit 10 on other frames 13.

[0027] Furthermore, the driving mechanism includes a second guide rail 15 , which is fixedly mounted on the electric slide 3 , and a driving motor 16 is fixedly mounted on the second guide rail 15 . A screw rod 17 is fixedly sleeved on the output shaft of the driving motor 16 , and the vertical plate 4 is threadedly connected to the outer surface of the screw rod 17 .

[0028] By starting the driving motor 16 to rotate the screw rod 17, the vertical plate 4 can be moved to the left or right, and the position of the drill bit 10 can be adjusted to achieve drilling at different positions on the surface of the circuit board.

[0029] Furthermore, a through hole 18 is formed on the base 1 , and the clamping mechanism includes a clamp 19 , a connecting block 20 located in the through hole 18 is fixedly connected to the clamp 19 , and a round block 21 is fixedly connected to the bottom of the connecting block 20 .

[0030] Furthermore, a second electric push rod 22 is fixedly installed at the bottom of the base 1, and a push-pull plate 23 is fixedly connected to the telescopic end of the second electric push rod 22. An inclined hole 24 is opened on the push-pull plate 23, and the inner wall of the inclined hole 24 is slidably connected to the outer surface of the round block 21.

[0031] By starting the second electric push rod 22, the push-pull plate 23 can be pushed to move, so that the inner wall of the inclined hole 24 can squeeze the outer surface of the round block 21, and then the two round blocks 21 can drive the two clamps 19 to move toward each other through the two connecting blocks 20, so that the two clamps 19 can clamp the circuit board in place to ensure stability during drilling.

[0032] Furthermore, the frame 13 has an inverted "U" shape, and the width of the frame 13 is greater than the width of the slot 8. Since the width of the frame 13 is greater than the width of the slot 8, the frame 13 will abut against the bottom of the disc 7 after being reset, and will not protrude above the disc 7 to cause interference between the frame 13 and the telescopic end of the first electric push rod 11 when the disc 7 rotates.

[0033] During use, the staff places the PCB circuit board between the two clamps 19, and then starts the second electric push rod 22 to push the push-pull plate 23 to move, so that the two clamps 19 can move toward each other to clamp the circuit board in place, and then the vertical plate 4 can be adjusted to the top of the position where the circuit board needs to be drilled through the electric slide 3 and the drive motor 16. When drill bits 10 of different sizes need to be selected for drilling, the brake motor 5 can be started to make the rotating shaft 6 drive the disc 7 to rotate, so that different drill bits 10 can be rotated to the bottom of the first electric push rod 11. After selecting the drill bit 10 that needs to be drilled, the staff can start the first electric push rod 11 and the drill rig 9 directly below the first electric push rod 11, so that the telescopic end of the first electric push rod 11 pushes the frame 13 to move downward and stretches the spring 14, so that the drill rig 9 can drive the rotating drill bit 10 to move downward, and finally the clamped and positioned circuit board can be drilled.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
