[0001] The invention relates to the field of circuit board production, and in particular to a machine for drilling holes in circuit boards. Background Art

[0002] During the processing of PCB circuit boards, it is necessary to punch holes in the PCB circuit boards. When punching holes in the PCB circuit boards, most of the existing methods use clamping power equipment to clamp and fix the circuit boards at both ends, which results in a large area of ​​​​the bottom of the circuit board being suspended. When the drilling position is located in the suspended area of ​​the circuit board, it is not conducive to drilling the circuit board, and it is easy to cause the suspended position to bend or break when it is pressed. Secondly, it is difficult to ensure the accuracy of drilling. Summary of the invention

[0003] The purpose of the present invention is to provide a machine for drilling holes in a circuit board.

[0004] The technical problem of the present invention is mainly solved by the following technical solutions:

[0005] A machine for drilling holes in a circuit board, comprising a table suspended by legs:

[0006] A collecting hopper is suspended below the table, wherein a vertical pipe is provided at the discharge port at the bottom of the collecting hopper, a fan is provided in the vertical pipe, and a dust bag is coated on the bottom end of the vertical pipe, and a dropping port is provided on the table inside the opening of the collecting hopper, wherein an auxiliary mechanism is mounted above the dropping port, and a fixing plate and a clamping plate parallel to the auxiliary mechanism are also arranged on the table on both sides of the dropping port, the clamping plate is driven by an electric push rod I, wherein a rectangular notch is arranged on the corner edge on one side of the top of the clamping plate, the auxiliary mechanism comprises a support plate mounted above the dropping port, wherein the support plate is driven by an electric push rod II, and a long strip dropping opening is arranged in the middle of the support plate, and a plurality of groups of arc grooves are evenly arranged on the top surface of the support plate on both sides of the dropping opening, wherein a U-shaped pipe connecting two groups of arc grooves corresponding to both sides of the dropping opening is arranged at the bottom of the support plate, and exhaust pipes are also arranged on both sides of the support plate, wherein one group of exhaust pipes is connected to the arc groove in the middle area of ​​the support plate through a pipe, and the other group of exhaust pipes is connected to the arc grooves at both ends of the support plate through a pipe.

[0007] Preferably, the top of the support plate and the bottom of the rectangular notch are in the same horizontal plane, and the length of the clamping plate is greater than the width of the blanking opening.

[0008] Preferably, a sliding opening for the electric push rod II to pass through is provided at the bottom of the fixing plate.

[0009] Preferably, the exhaust pipe is fixed on the outer side wall of the support plate, wherein the height of the exhaust pipe is lower than the horizontal plane of the top end of the support plate, and the exhaust pipe is connected to the vacuum pump through a hose.

[0010] Preferably, discharge pipes are provided on the side walls of the collecting hopper on both sides of the vertical pipe, wherein the side walls of the vertical pipe in the collecting hopper are of a mesh structure, and a protective cover with a mesh structure is also provided on the top of the vertical pipe.

[0011] The beneficial effects of the present invention are as follows: the present invention clamps and fixes the circuit board above the support plate by means of the clamping plate and the fixing plate, and changes the position of the support plate according to the drilling position of the circuit board. The specific steps are as follows: the electric push rod II drives the support plate to move so that the drilling position of the circuit board is located directly above the blanking opening on the support plate. At this time, the vacuum pump works to evacuate the arc groove through the exhaust pipe and the U-shaped pipe to adsorb and fix the circuit board on the support plate. At this time, the support plate plays a supporting and fixing role on the suspended areas on both sides of the drilling position of the circuit board, so as to improve the stability and drilling accuracy of the circuit board when drilling it. When the drilling mechanism is reset upward, the circuit board is adsorbed and fixed on the support plate, so that it is not easy to lift the circuit board when the drill bit is pulled out from the drilling position.

DETAILED DESCRIPTION

[0016] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0017] A machine for drilling holes in a circuit board, comprising a table 1 suspended by legs:

[0018] A collecting hopper 2 is suspended below the table 1, wherein a vertical pipe 3 is provided at the discharge port at the bottom of the collecting hopper 2, a fan 4 is provided in the vertical pipe 3, wherein a dust bag 5 is provided on the bottom end of the vertical pipe 3, a material drop port 6 is provided on the table 1 in the opening of the collecting hopper 2, wherein an auxiliary mechanism 7 is arranged above the material drop port 6, and a fixing plate 8 and a clamping plate 9 parallel to the auxiliary mechanism 7 are also provided on the table 1 on both sides of the material drop port 6, wherein the clamping plate 9 is driven by an electric push rod 110, wherein a rectangular notch 11 is provided on the corner edge of one side of the top of the clamping plate 9;

[0019] The auxiliary mechanism 7 includes a support plate 71 mounted on the upper side of the blanking opening 6, wherein the support plate 71 is driven by an electric push rod II72, and a sliding opening 12 for the electric push rod II72 to pass through is provided at the bottom of the fixed plate 8, and a long strip blanking opening 73 is also provided in the middle of the support plate 71, and a plurality of groups of arc grooves 74 are evenly provided on the top end surface of the support plate 71 on both sides of the blanking opening 73, wherein a U-shaped tube 75 connecting two groups of arc grooves 74 corresponding to both sides of the blanking opening 73 is provided at the bottom of the support plate 71, and exhaust pipes 76 are also provided on both sides of the support plate 71, wherein one group of exhaust pipes 76 is connected to the arc groove 74 in the middle area of ​​the support plate 71 through a pipe, and the other group of exhaust pipes 76 is connected to the arc grooves 74 at both ends of the support plate 71 through a pipe.

[0020] like Figure 1 As shown, the top of the support plate 71 and the bottom of the rectangular notch 11 are in the same horizontal plane, and the length of the clamping plate 9 is greater than the width of the blanking opening 73 .

[0021] In this embodiment, the exhaust pipe 76 is fixed on the outer wall of the support plate 71, wherein the height of the exhaust pipe 76 is lower than the horizontal plane of the top of the support plate 71, and the exhaust pipe 76 is connected to the vacuum pump through a hose.

[0022] like Figure 1 As shown, discharge pipes 13 are arranged on the side walls of the hopper 2 on both sides of the vertical pipe 3, wherein the side walls of the vertical pipe 3 in the hopper 2 are of a mesh structure, and a protective cover 14 of a mesh structure is buckled on the top of the vertical pipe 3. The discharge pipe 13 is used to discharge large-volume impurities accumulated at the bottom of the hopper 2, and the protective cover 14 prevents large-volume impurities from entering the vertical pipe 3 and the dust bag 5.

[0023] The working principle of the present invention is as follows: when in use, one end of the circuit board is placed in the rectangular notch 11, and the other end is located on the support plate 71 and supported by it. Then the electric push rod I10 drives the clamping plate 9 to move leftward, and the circuit board is clamped and fixed above the support plate 71 through the clamping plate 9 and the fixing plate 8, and the position of the support plate 71 is changed according to the drilling position of the circuit board. The specific steps are as follows: the electric push rod II72 drives the support plate 71 to move, so that the drilling position of the circuit board is located just above the blanking opening 73 on the support plate 71. At this time, the vacuum pump works to vacuum the arc groove 74 through the exhaust pipe 76 and the U-shaped pipe 75, so as to adsorb and fix the circuit board on the support plate 71. At this time, the support plate 71 plays a supporting and fixing role on the suspended areas on both sides of the drilling position of the circuit board, so as to improve the stability and drilling accuracy of the circuit board when drilling it. When the drilling mechanism is reset upward, the circuit board is adsorbed and fixed on the support plate 71, so that it is not easy to bring up the circuit board when the drill bit is pulled out from the drilling position;

[0024] When drilling, the corresponding exhaust pipe 76 and vacuum pump are opened according to the width of the circuit board. When the width of the circuit board only covers the arc groove 74 in the middle area of ​​the top of the support plate 71, only the exhaust pipe 76 and vacuum pump connected to the middle arc groove 74 need to be opened. When the circuit board completely covers the arc groove 74 above the support plate 71, all the exhaust pipes 76 and vacuum pumps can be opened to prevent waste.

[0025] When drilling, the debris falls into the collecting hopper 2 through the drop port 6, and the fan 4 generates suction to draw the debris obtained from the drilling and the dust diffused in the collecting hopper 2 into the vertical pipe 3 and the dust removal bag 5 for filtration, thereby processing and collecting the dust, and large-volume impurities are filtered through the vertical pipe 3 and the aperture of the side wall of the protective cover 14, so that the large-volume impurities are accumulated in the collecting hopper 2 and discharged through the discharge pipe 13.

[0026] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
