Description

Drill pin grinding device

This creation is a drill pin grinding device, especially a drill pin grinding device that only opens and closes the jaws and moves up and down in the preparation position.

In order to mount electronic components on a printed circuit board, a drill pin (or micro drill pin) is usually used for drilling. When the drill pin is used for a period of time, it needs to be ground with a grinder. To restore its sharp blade. Please refer to the first figure, that is, the rotary type four-station module of Taiwan Patent Application No. 105133462, which includes a clamping drill station 11, a rotation angle adjustment and front-back position station 12, and a drill grinding station 13 and a drill pin removal station 14 and other four work stations, and a grinding wheel 16 (that is, a grinding wheel module) is equipped with a double grinding wheel (including a 75 ° included angle of the back of the drill bit that is ground first) Grinding wheel 17, and a left grinding wheel 18 after grinding to form a 65 ° included angle of the blade of the drill. Before the right grinding wheel 17 grinds the drill pin 19, it needs to be held by a clamping jaw (not shown in the figure). The front end of the drill 19 (the grip position is about 1 ~ 1.5 times the diameter of the drill from the needle of the drill 19) to protect the drill 19 from being broken by the right grinding wheel 17 and the left grinding wheel 18 during grinding. .

When the drilling pin 19 is finished grinding, it is necessary to completely retract the grinding seat 16 of the grinder 15, then remove the clamping jaw, and then transfer the drilling pin 19 to the drilling pin removal station 14. Although the grinding of the drilling pin 19 can be automated, it is still necessary to manually set the relevant settings at the beginning. Since the right and left grinding wheels 17 and 18 are inclined toward the jaw, the jaws are opened and When moving down, if the operator accidentally forgets that the grinder 15 must have this further "retract" action, and if the gripper 15 is moved longitudinally before the grinder 15 is retracted, it may cause the gripper Hit the left grinding wheel 18, so how to prevent the accidental collision between the gripper and the grinding wheel is a problem that needs to be solved urgently, and there are doubts about the high cost of setting up the work mode of the four workstations.

The reason is how to solve the problem of accidental collision between the clamping jaw and the grinding wheel that may occur when the drill is finished. After the author devoted himself to experiments, tests and studies, he finally got a drill grinding device. In addition to the problem of accidental collision between the claw and the grinding wheel, it can also have the effects of reducing costs and simplifying the structure. That is to say, the problem to be solved in this creation is how to overcome the problem of accidental collision between the jaw and the grinding wheel, so that the upper and lower movement of the jaw can be more secure, and how to overcome the need for the drill pin clamping module to The problem of moving back and forth between the grinding position and the grinding preparation position, and how to overcome the problem that the collet assembly needs to move synchronously with the protection cylinder assembly.

This creation discloses a drill pin grinding device, including a drill pin clamping module, including a protection cylinder assembly, including a bearing platform, a clamping jaw and a collet bearing portion on the bearing platform, and a collet. The assembly is arranged on the collet bearing part and comprises a collet for holding a drill pin, wherein the clamping jaw is used for fixing the drill pin to protect the drill pin from breaking during grinding and a movement The module includes a moving track for linearly moving the bearing platform on the moving track to move the drill pin holding module back and forth between a grinding preparation position and a grinding position. When the needle clamping module is located at the grinding preparation position, the clamping jaw can be moved up and down to open and close to clamp or release the drilling needle.

This case can also be a drill pin grinding device, including a collet assembly, including a collet for holding a drill pin, a protection cylinder assembly, including a clamping jaw for fixing the drill pin, to protect the drill. The needle does not break during grinding, and a moving module includes a moving track for the collet assembly and the protection cylinder assembly to move linearly, so that the drill pin back and forth between a grinding preparation position and a grinding position Movement, wherein when the drill pin is located at the grinding preparation position, the clamping jaw can be moved up and down to be clamped or released The drill.

The rotation of the drill pin 20 is to adjust to a more accurate grinding angle, and the second motor 52 It is used to drive the drill bit 20 to advance GF or back DB as shown in the eighth figure. To move the drill bit 20 back and forth, it is to adjust to a more precise grinding length.

Please refer to the ninth to eleventh figures. The protective cylinder assembly 23 of this creation includes a bearing platform 110, a cylinder 101 connected to the clamping jaw 24, and a third motor disposed at a position opposite to the clamping jaw 24 and on the other side of the bearing platform 110. 123. The supporting platform 110 is used for supporting the collet supporting part 111 of the clamping jaw 24 and the collet assembly 21, the cylinder 101 is used to control the opening and closing OP, CL of the clamping jaw 24 (as shown in the tenth figure), and the third motor 123 It is used to control the jaw 24 to move up and down (as shown in the eleventh figure).

Please refer to the twelfth figure. The mobile module 301 of the present invention includes a groove 32 and a moving track 31 located in the groove 32 and used for the linear movement of the drill bit clamping module 201. The loading platform 110 of the drill pin clamping module 201 further includes a driving portion 112 (as shown in the ninth figure). The stage 110 moves on the moving rail 31 to move the drill pinching module 201 between the grinding preparation position and the grinding position.

Please refer to the second and twelfth figures together. Before grinding, the drill pin holding module 201 will be located at the grinding preparation position 40 (as shown in the second figure). At the grinding preparation position 40, the collet 22 will first hold the drill pin 20, and then move the jaw 24 to an appropriate position to hold and fix the drill pin 20. After both the collet 22 and the jaw 24 hold the drill pin 20, the drill pin holding module 201 moves linearly along the moving track 31 to the grinding position 30 (as shown in FIG. 12) for grinding. In the grinding position 30, the right grinding wheel 17 and the left grinding wheel 18 in the grinding machine 15 as shown in the first figure are used to grind the drill pin 20. After the grinding is completed, the drill pin holding module 201 will first move from the grinding position 30 to the grinding preparation position 40 along the moving track 31. When the drill pin 20 on the drill pin holding module 201 is located at the grinding preparation position 40, the clamp The claw 24 then moves up and down and opens and closes to clamp or release the drill pin 20, so that the effect that the two mechanisms of the claw 24 and the right grinding wheel 17 and the left grinding wheel 18 do not easily collide with each other can be obtained.

When the drilling pin 20 is located at the grinding position 30 and the grinding is completed, that is, the clamping jaw 24 is excluded from any upward and downward movement in the grinding position 30. Before the drilling pin 20 is withdrawn, the drilling pin clamping module 201 must first return to the grinding preparation position 40 , Then open the clamping jaw 24, the clamping jaw 24 releases the drill bit 20 after grinding at the grinding preparation position 40, and then moves the clamping jaw 24 downward, and then the next drill bit to be ground can be clamped (not shown in the figure) )Actions. of course, Before the drill 20 is ground, the clamping jaw 24 must first hold the drill 20 at the grinding preparation position 40, and then the drill holding module 201 moves linearly from the grinding preparation position 40 to the grinding position 30 for the right grinding wheel 17 and the left The grinding wheel 18 grinds the drill pin 20.
