On extension line of the PIN grooves 1111 to Y-axis negative direction, and with the end interval setting of PIN grooves 1111, i.e. PIN grooves 1111 with PIN
The X-axis coordinate of groove 1113 is identical.
Also interval offers multiple flutings 1115 on work top 111, and fluting 1115 is the strip of insertion workbench 11
Groove, fluting 1115 extends along parallel to X-direction, that is, 1115 bearing of trend of slotting hangs down with the bearing of trend of PIN grooves 1111
Directly.The end of each fluting 1115 is spaced with PIN grooves 1111.In the present embodiment, multiple flutings 1115 are respectively at PIN grooves
1111 both sides, with the both sides of PIN grooves 111 formed two groups totally 6 fluting 1115, i.e., first group flutings 1115 opened with second group
Groove 1115.Every group totally 3 fluting 1115.First group of fluting 1115 sets with second group of fluting 1115 in interlaced in Y direction
Put, i.e., one of first group fluting 1115 in Y direction (bearing of trend of PIN grooves 1111) in second group of fluting 1115
Most edge, first group remaining fluting 1115 is between two flutings 1115 that second group is in Y direction.
Multiple pressing part 13 is actively located in fluting 1115 respectively, i.e., each pressing part 13 is arranged in corresponding one and opens
In groove 1115.Pressing part 13 includes compressing tablet 131 and the connector 133 being connected on compressing tablet 131.Compressing tablet 131 is thin rounded flakes, living
It is dynamic to be arranged on corresponding fluting 1115, and have a diameter larger than the width of fluting 1115.Connector 133 is round bar shape, and one
End is coaxially connected on compressing tablet 131, and the other end is actively located in fluting 1115.Compressing tablet 131 can also for square, triangle,
The symmetric figures such as regular polygon, strip.In the present embodiment, compressing tablet 131 is pressing plate mushroom head, and connector 133 is metal
Roller.
Multiple actuators 15 are arranged at the lower section of work top 111, and the connector 133 with multiple pressing part 13 connects respectively
Connect.Each actuator 15 correspondence fluting 1115 is arranged under work top 111, and with connector 133 away from compressing tablet 131 one end
Connection.Actuator 15 is also electrically connected with control module 50.In the present embodiment, actuator 15 is cylinder and multiple actuators
15 are independently arranged mutually.
The correspondence of main axle structure 30 is suspended in work top 111 and sets, and is used to drill the PCB on work top 111
Operation.Main axle structure 30 includes drill spindle 31 and the presser feet 33 being movably arranged on drill spindle 31.Drill spindle 31 with
Control module 50 is electrically connected with.
Control module 50 is set adjacent to workbench 10, and is electrically connected with multiple actuators 15 and main axle structure 30.Control
The controllable pressing part 13 positioning PCB of module 50, to coordinate the bore operation of main axle structure 30.In the present embodiment, mould is controlled
Group 50 is servo controller.
During assembling PCB drilling equipments 100, pressing part 13 is actively located in corresponding fluting 1115, by actuator 15
It is arranged at work top 111 times and is connected with corresponding pressing part 13.Main axle structure 30 is correspondingly arranged on work top 111
Side.Control module 50 is set adjacent to workbench 10 and is electrically connected with respectively at drill spindle 31 and multiple actuators 15.
During PCB 100 operations of drilling equipment, actuator 15 drives pressing part 13 to be moved along fluting 1115, and will press part 13
It is positioned at edge of the fluting 1115 away from work top 111, and makes orthogonal between multiple pressing parts 13 and respective independence.Will
PCB is placed on work top 111, and PIN grooves 1111 position direction and the angle of PCB, and PIN groove 1113 coordinates PIN grooves 1111
PCB is positioned on work top 111.The control control main axle structure 30 of module 50 is moved to work top 111.When presser feet 33 is touched
During to PCB, be pressed in PCB on work top 111 by the control control pause movement of presser feet 33 of module 50.And drill spindle 31
Continue to move down 5~20 seconds and carry out bore operation with to PCB.Within a period of time of the pause of presser feet 33, presser feet can be ensured
33 have time enough to flatten PCB.
During drilling, when needing the warpage position to PCB to carry out pressing plate, actuator 15 control it is corresponding pressing part 13 along
Fluting 1115 is moved to the center of work top 111.When edge of the part 13 in PCB is pressed, actuator 15 drives pressing part
13 move to work top 111, to drive compressing tablet 131 to carry out pressing plate to the warpage position of PCB.Pressing plate pressure of the compressing tablet 131 to PCB
Power determined by actuator 15, and the order of severity that can be stuck up according to plate is adjusted.In the present embodiment, actuator 15 is adjusted
Air pressure size be adjustable platen pressure.
There is the plate of the PCB of dissymmetrical structure to stick up position by pressing part 13 pairs carries out pressing plate, and then solves because plate sticks up
And the problem of the hole position low precision for causing, improve borehole accuracy.The breaking rate also reduced simultaneously caused by plate sticks up is high, abnormal
Alarm is frequent and controls the quality problems such as deep low precision.
When PCB drilling equipments 100 are in off position or need not carry out pressing plate to the somewhere of PCB, correspondence position
The pressing part 13 put can be at halted state and stay in one end of fluting 1115, i.e. the outer end or the inner of fluting 1115.Now,
Because the movement between multiple pressing part 13 is unaffected mutually, other pressing parts 13 can carry out pressing plate to warpage position, without
The pressing part 13 of work will not be formed to the hole site to be drilled of PCB and stopped.Further, since multiple flutings 1115 are in PIN grooves 1111
Both sides it is usually staggered, which determine the positions of multiple pressing parts 13, so when ensure that pressing plate operation PCB stress
Uniformity.
It is appreciated that every group of number of fluting 1115 can be set as needed, first group and second group of fluting
1115 number also can be unequal.
It is appreciated that the bearing of trend of fluting 1115 can also be set with the bearing of trend oblique angles of PIN grooves 111.
Embodiment described above only expresses several embodiments of the invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Shield scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
