Description

Drill point grinding device and method thereof
Technical Field
The present invention relates to a drill point grinding device and a method thereof, and more particularly, to a drill point grinding device and a method thereof, in which the opening, closing, and up-and-down movement of a clamping jaw are limited to a grinding preparation position.
Background
In order to mount electronic components on a printed circuit board, a drill (or micro-drill) is typically used to drill a hole, and after the drill is used for a period of time, the drill needs to be ground by a grinder to restore its sharp edge. Referring to fig. 1, a rotary four-station module of chinese patent application No. 201611005501.4 (taiwan No. 105133462) includes four stations, i.e., a drill point clamping station 11, a rotation angle and front and rear position adjusting station 12, a drill point grinding station 13, and a drill point taking-out station 14, and a grinding seat 16 of a grinder 15 (i.e., a grinding wheel module) is provided with a double grinding wheel (including a right grinding wheel 17 for grinding and cutting a 75 ° angle of a back of a drill point and a left grinding wheel 18 for grinding and forming a 65 ° angle of a drill point blade). Before the right grinding wheel 17 grinds the drill bit 19, a clamping jaw (not shown in the figure) is used to hold the front end of the drill bit 19 (the holding position is a position which is about 1-1.5 times of the diameter of the drill bit from the needle head of the drill bit 19) so as to protect the drill bit 19 from being broken by the right grinding wheel 17 and the left grinding wheel 18 during grinding.
When the drill point 19 is finished, the grinding seat 16 of the grinder 15 is completely removed, the clamping jaws are removed again, and the drill point 19 is transferred to the drill point removal station 14. Although the grinding of the drill bit 19 can be automated, it is still necessary to manually perform the related setting at first, since the right grinding wheel 17 and the left grinding wheel 18 are both inclined toward the clamping jaws, when the clamping jaws are opened and moved downward, if the operator forgets the further "retreating" action of the grinder 15 carelessly, and moves the clamping jaws longitudinally before the grinder 15 is not retreated, the clamping jaws may collide with the left grinding wheel 18, so that the problem that the accidental collision between the clamping jaws and the grinding wheel needs to be solved is solved, and the operation modes of four work stations are respectively provided, which is also considered to be too costly.
Therefore, the inventor of the present invention has made an effort to provide a drill point grinding apparatus and method thereof, which can effectively avoid the accidental collision between the clamping jaw and the grinding wheel, and can reduce the cost and simplify the structure. The problem to be solved by the present invention is how to overcome the problem that the clamping jaw and the grinding wheel may accidentally collide with each other, so that the vertical movement of the clamping jaw is more secured, how to overcome the problem that the drill point clamping module needs to move back and forth between the grinding position and the grinding preparation position, and how to overcome the problem that the collet chuck assembly needs to move synchronously with the protection cylinder assembly.

Detailed Description
In order to ensure that the clamping jaws for fixing the drill point can not collide with a grinding wheel any more when being moved away, the invention provides a drill point grinding device comprising a drill point clamping module and a grinding wheel module and a grinding method thereof. That is, after the completion of grinding, before or after further operation of the grinding wheel module, the drill point of the present invention moves the holding jaws away from the grinding wheel module to the grinding preparation position so that the holding jaws and the grinding wheel module do not collide with each other.
Referring to fig. 2, a drill point grinding device 202 of the present invention is shown, which includes a drill point clamping module 201 (i.e., an integrated module), a moving module 301, and grinding wheel modules of the right grinding wheel 17 and the left grinding wheel 18 shown in fig. 1, wherein the drill point clamping module 201 includes a collet assembly 21 and a protection cylinder assembly 23 shown in fig. 3. The collet assembly 21 includes a collet 22 for holding the drill bit 20, and the protection cylinder assembly 23 includes jaws 24 for grasping and fixing the drill bit 20 to protect the drill bit 20 from breaking during grinding.
Referring to fig. 4, the collet assembly 21 of the present invention includes a collet 22 (or elastic collet), a gas nozzle 50, a first motor 51 and a second motor 52. When air cap 50 is inflated, collet 22 is opened forward as shown in FIG. 5 to insert drill bit 20, and when air cap 50 is stopped, collet 22 is retracted rearward as shown in FIG. 6 to grip drill bit 20. The first motor 51 is used to drive the drill 20 in forward rotation NT or reverse rotation RT as shown in fig. 7, in order to rotate the drill 20 for adjustment to a more precise grinding angle, and the second motor 52 is used to drive the drill 20 in forward and backward movement GF or backward movement DB as shown in fig. 8, in order to adjust the drill 20 to a more precise grinding length.
Referring to fig. 9-11, the protection cylinder assembly 23 of the present invention includes a supporting platform 110, a cylinder 101 connected to the clamping jaw 24, and a third motor 123 disposed at the other side of the supporting platform 110 opposite to the clamping jaw 24. The carrying table 110 is used for carrying the clamping jaws 24 and the collet carrying part 111 carrying the collet assembly 21, the cylinder 101 is used for controlling the opening and closing OP, CL of the clamping jaws 24 (as shown in FIG. 10), and the third motor 123 is used for controlling the up-and-down movement of the clamping jaws 24 (as shown in FIG. 11).
Referring to fig. 12, the moving module 301 of the present invention includes a groove 32 and a moving rail 31 located in the groove 32 and allowing the drill point clamping module 201 to move linearly. The carrier 110 of the drill-pin clamping module 201 further includes a driving portion 112 (as shown in fig. 9), and the driving portion 112 can move the carrier 110 on the moving rail 31, so that the drill-pin clamping module 201 can move between the grinding-ready position and the grinding position.
Referring to fig. 3, the drill clamping module 201 of the present invention further includes a laser sensor 25 connected to the collet assembly 21 through a sensor carrying portion 26 for detecting whether there is a drill 20 in the collet 22.
Referring to fig. 2 and 12, before grinding, the drill-pin clamping module 201 is located at the grinding-preparation position 40 (shown in fig. 2). In the grind ready position 40, the collet 22 first grips the drill bit 20 and then moves the jaws 24 into position to grip and hold the drill bit 20. After the collet 22 and the jaws 24 both hold the drill bit 20, the drill bit holding module 201 moves linearly along the moving track 31 to the polishing position 30 (shown in FIG. 12) for polishing. At the grinding position 30, the drill point 20 is ground using the right grindstone 17 and the left grindstone 18 in the grinder 15 shown in fig. 1. After the grinding is completed, the drill point clamping module 201 will first return from the grinding position 30 to the grinding preparation position 40 along the moving track 31, and when the drill point 20 on the drill point clamping module 201 is located at the grinding preparation position 40, the clamping jaw 24 will move up and down and open and close to clamp or release the drill point 20, so that the effect that the clamping jaw 24 and the right grinding wheel 17 and the left grinding wheel 18 are not easy to collide with each other can be obtained.
When the drill point 20 is at the grinding position 30 and grinding is completed, i.e. any up-and-down movement of the jaws 24 at the grinding position 30 is excluded, the drill point holding module 201 must first return to the grinding preparation position 40 before the drill point 20 is withdrawn, then the jaws 24 are opened, the jaws 24 release the ground drill point 24 at the grinding preparation position 40, then the jaws 24 are moved downwards again, and then the action of holding the next drill point to be ground (not shown) can be performed. Of course, before the drill point 20 is ground, the clamping jaws 24 must first clamp the drill point 20 at the grinding preparation position 40, and then the drill point clamping module 201 moves linearly from the grinding preparation position 40 to the grinding position 30, so that the right grinding wheel 17 and the left grinding wheel 18 grind the drill point 20.
In accordance with another aspect of the invention, a method for grinding a drill point 20 using a drill point grinding apparatus 202 is disclosed, wherein the drill point grinding apparatus 202 comprises a grinding wheel module (i.e. a grinder 15) and a drill point holding module 201 for holding the drill point 20, such that the grinding wheel module grinds the drill point 20, the method comprising, before grinding, holding the drill point 20 with holding jaws 24 to protect the drill point 20 from breaking during grinding, after grinding, before or after further action of the grinding wheel module, moving the holding jaws 24 laterally away from the grinding wheel module to a grinding preparation position 40 (i.e. a position where the holding jaws 24 are intended to be moved longitudinally) where they do not collide with each other, and releasing the ground drill point 20 at the grinding preparation position and holding the next drill point to be ground.
