Description

Technical Field

[0001] This invention relates to a grinding apparatus, and more particularly to a grinding apparatus that provides grinding micro drill bits and has a precision and stable drill bit rotation. Background Technology

[0002] Currently, micro drill bits are frequently used for some precision drilling processes. These micro drill bits are manufactured by grinding a high-speed steel material that meets the requirements through a precision grinding device, especially the cylindrical end of which must be sharpened for use in drilling. The grinding quality is also closely related to the stability, quality, or efficiency of drilling.

[0003] Because of the small size of the drill bit and its high length-to-diameter ratio, it must be ground with great care. In addition to using precise image detection to determine its cutting length, drill diameter, angle correction and feed rate positioning, it must also be fixed with a well-designed fixture in order to re-grind a drill bit that meets the standard and restore it to a state where it can smoothly drill holes on the circuit board.

[0004] Current grinding equipment, while capable of holding drill bits, is prone to wobble when the drill bits rotate, making grinding difficult, increasing the defect rate and affecting costs. In addition, it requires additional manpower for manual adjustment, affecting work efficiency and hindering the development of automation. Summary of the Invention

[0005] In view of the above-mentioned shortcomings, the present invention has a high-speed precision drill bit grinding device to solve the problems of existing grinding equipment, which are prone to wobble when the drill bit rotates, making it difficult to grind, increasing the defect rate and affecting costs. In addition, it also requires additional manpower for manual adjustment, which affects work efficiency and is not conducive to the development of automation.

[0006] It includes: a grinding unit, which includes a grinding assembly; a clamping unit, which includes a first power source and a clamping part connected to the first power source, the clamping part providing a clamping end for a micro drill bit, the other end of the micro drill bit facing the grinding assembly; and a support unit, which includes a second power source, a first transmission module connected to the second power source, and a support module, the first transmission module being connected to the support module, the support module including a first support member and a second support member. When grinding the micro drill bit, the first power source drives the clamping part to rotate, causing the micro drill bit to rotate synchronously and contact the grinding assembly for grinding. The second power source drives the first transmission module, the first transmission module driving the first support member and the second support member to reciprocate and pivot, thereby clamping the micro drill bit and keeping the micro drill bit stable.

[0007] Furthermore, the second power source has a drive shaft with a cam on it; the first transmission module includes a base and a slider. One side of the base has a groove facing the second power source, and the slider slides within the groove. The front end and top of the slider are respectively provided with a first pusher and at least one second pusher. The bottom of the slider has an elastic component that contracts to pull the slider downwards. When the second power source operates, the cam contacts the first pusher, causing the slider to move upwards. The support module also includes a plate, with the first and second supports pivotally mounted on it. The bottom of each support has a column, and each column is provided with at least one first transmission component and at least one second transmission component. The first and second transmission components are located on opposite sides of the second pusher component, and each component has a spring connecting its two ends at the other end. The first transmission module is driven by the second power source. When the second power source operates, the cam contacts the first pusher component, causing the slider to move upward. The second pusher component pushes the first and second transmission components, causing the first and second support components to pivot, so that the tops of the first and second support components move away from each other. When the slider moves downward, the second pusher component moves away from the first and second transmission components, and the tension of the spring causes the first and second support components to pivot, so that the tops of the first and second support components move closer together to clamp the tip of the micro drill bit.

[0008] Furthermore, the groove is also provided with at least one slide rail that engages with the slider.

[0009] Furthermore, the first pusher, the second pusher, the first transmission member, and the second transmission member are bearings.

[0010] Furthermore, the plate includes a shaft, one end of which is provided with at least one bearing, and the other end is provided with a locking part that is connected to the first support member. The other side of the locking part is also provided with a bearing. The second support member passes through the shaft and is connected to the other side of the locking part.

[0011] Furthermore, the first support member includes a first bottom rod, a disc body, and a first top rod. The disc body has a first through hole for passing through the shaft body and engaging with the locking part. The first bottom rod is located on one side of the bottom of the disc body, and the first top rod is located on the other side of the top of the disc body. The second support member includes a second bottom rod, a chamber, and a second top rod. The chamber has a second through hole for passing through the shaft body and enclosing the locking part and the disc body. The second bottom rod is located on one side of the bottom of the chamber, and the second top rod is located on the other side of the top of the chamber. A predetermined distance is provided between the first bottom rod and the second bottom rod, and between the first top rod and the second top rod.

[0012] Furthermore, a tube is fitted onto each bearing of the shaft, one end of which has a stop, and multiple bearings are spaced apart on the outer side of the tube. The stop is connected to the outer side of the enclosure of the second support member.

[0013] Furthermore, a bracket extends from the outer side of the enclosure of the second support member, and an elastic component two is provided at the bottom of the bracket. The other end of the elastic component two is connected to the plate body, and the tension of the elastic component two pushes the second support member.

[0014] Furthermore, the first push rod and the second push rod have a predetermined angle, and the top surface of the first push rod and the second push rod are respectively provided with a clamping piece, each clamping piece corresponding to each other, and clamping the micro drill bit with each clamping piece.

[0015] Furthermore, the grinding unit also includes at least one optical module for capturing images of the micro drill bit and outputting the image of the micro drill bit to a display.

[0016] The beneficial effects of this invention are:

[0017] The present invention has a high-speed precision drill bit grinding device that can automatically complete the feeding, clamping and grinding, cleaning and outputting of micro drill bits. Furthermore, the device adopts a three-dimensional configuration, which can reduce the size of the invention. Therefore, more units of the present invention can be placed in the same space.

[0050] Please refer to Figures 8 to 12The usage process of this invention is as follows:

[0051] A drill bit conveying platform 40 is provided on one side of the clamping unit 20. The drill bit conveying platform 40 includes a first conveying unit 41, which includes a first bearing part 410, a second transmission module 411 and a second bearing part 412.

[0052] The first support portion 410 is provided with at least one transverse limiting hole 4101, and a notch 4102 is provided on one side of the first support portion 410.

[0053] The second transmission module 411 includes a sliding member 4111 and a third power source connected to the sliding member 4111. The sliding member 4111 is disposed on the bottom surface of the first bearing part 410. The top surface of the sliding member 4111 is provided with a push rod 4112 that passes through the limiting hole 4101. The third power source drives the sliding member 4111 to move.

[0054] The first support portion 410 has a predetermined angle, making the first support portion 410 inclined. The first support portion 410 has an accommodating space that communicates with the outside and the notch 4102. The second transmission module 411 also includes a sensor electrically connected to the third power source, which is used to start or stop the third power source. The first support portion 410 is provided to hold multiple boxes B, each box B is provided with multiple accommodating slots, and each accommodating slot is provided to insert a miniature drill bit A. The sensor is used to monitor the notch 4102.

[0055] The second support portion 412 is located below the first support portion 410.

[0056] A second conveying unit 42, one end of which is connected to the notch 4102, the second conveying unit 42 includes a fourth power source, and the second conveying unit 42 is driven by the fourth power source.

[0057] When at least one of the boxes B enters the second conveying unit 42 through the notch 4102, the sensor drives the third power source to move the sliding member 4111, and the push rod 4112 pushes each box B. Since the first bearing part 410 is inclined, each box B slides toward the notch 4102 after being pushed.

[0058] The fourth power source of the second conveying unit 42 is electrically connected to a sensor. The fourth power source is started or stopped by the sensor. The second conveying unit 42 moves the box B forward a predetermined distance and then stops the fourth power source.

[0059] A lifting unit 43 includes a third conveying unit 430 and a third transmission module 431 connected to the third conveying unit 430. The third conveying unit 430 is slidably mounted on the third transmission module 431 and adjacent to the other end of the second conveying unit 42. The third transmission module 431 includes a fifth power source, which drives the third conveying unit 430 to rise or fall.

[0060] A stop 420 is pivotally mounted on one end of the second conveying unit 42 facing the lifting unit 43. The stop 420 is connected to a pivoting module, which includes at least one motor and one sensor. The stop 420 is pivoted by the pivoting module to stand upright on the second conveying unit 42, or the stop 420 is pivoted by the pivoting module to be stored below the second conveying unit 42. The stop 420 prevents the box B from entering the lifting unit 43.

[0061] A fourth conveying unit 44 is located below the second conveying unit 42. One end of the fourth conveying unit 44 is connected to the second bearing part 412, and the other end is adjacent to the lifting unit 43. When the third conveying unit 430 of the lifting unit 43 descends, the third conveying unit 430 is connected to the fourth conveying unit 44.

[0062] Please refer to Figures 13 to 16 Above the second conveying unit 42 of the drill bit conveying platform 40, a drill bit cleaning device 50 is provided. The drill bit cleaning device 50 includes: a transmission unit 51, which includes a sixth power source 510, a first frame 511 connected to the sixth power source 510, and at least one sliding member 512 connected to the first frame 511. The sliding member 512 is slidably mounted on at least one track 513.

[0063] The first frame 511 is provided with a first hollow part 5111 and at least one second hollow part 5112. The sixth power source 510 is connected to the first hollow part 5111, and the sliding member 512 is connected to the second hollow part 5112.

[0064] A cleaning unit 52 includes a second frame 520 and at least one clay layer 521 attached to the bottom surface of the second frame 520, one end of the second frame 520 being attached to the bottom of the first frame 511.

[0065] The second frame 520 is provided with at least one first through hole 5201, and the clay layer 521 is disposed in the first through hole 5201; the top surface and bottom surface of the second frame 520 are respectively provided with a plate 5202, and each plate 5202 is provided with a plurality of second through holes 5203, each second through hole 5203 corresponding to the first through hole 5201 and the clay layer 521, and the clay layer 521 is exposed intermittently in each second through hole 5203 by using each plate 5202.

[0066] The bottom of the second frame 520 is provided with a positioning plate 522. The positioning plate 522 is at a predetermined distance from the second frame 520. The positioning plate 522 is provided with a plurality of third through holes 5220, and each third through hole 5220 corresponds to each second through hole 5203.

[0067] When the drill bit delivery platform 40 delivers the box B to the area below the drill bit cleaning device 50, the sixth power source 510 is activated by a sensor, and the first frame 511 moves rapidly down along the track 513, causing the cutting edge A1 of each micro drill bit A in the box B to insert into the clay layer 521. Then, the sixth power source 510 drives the first frame 511 to move up, thus completing the cleaning of each micro drill bit A.

[0068] The dimensions of the box body B are the same as those of the second frame 520 and the positioning plate 522, and each of the slots of the box body B corresponds to each of the second through holes 5203 and each of the third through holes 5220. Therefore, the drill bit cleaning device 50 can achieve the purpose of cleaning multiple micro drill bits A at the same time, overcoming the disadvantage of the existing drill bit cleaning device that cannot clean multiple drill bits at the same time.

[0069] Please refer to Figure 1 The clamping part 22 provides a clamping part for holding one end of the cleaned micro drill bit A. The cutting edge A1 of the micro drill bit A faces the grinding assembly 11. The front end of the micro drill bit A is clamped by each clamping piece 3314 and 3324. The optical module captures the image of the micro drill bit A and outputs the image of the micro drill bit A to a display (not shown in the figure).

[0070] Before grinding the micro drill bit A, the first power source 21 drives the clamping part 22 to rotate so that the cutting edge A1 of the micro drill bit A faces the grinding assembly 11. The position of the cutting edge of the micro drill bit A is confirmed by the optical module. At the same time, the second power source 31 drives the first transmission module 32, and the first transmission module 32 drives the first support member 331 and the second support member 332 to reciprocate and pivot.

[0071] Furthermore, when the second power source 31 operates, the cam 312 contacts the first pusher 3221, causing the slider 322 to move upward. When the slider 322 moves upward, the second pusher 3222 simultaneously pushes the first transmission member 334 and the second transmission member 335, causing the first support member 331 and the second support member 332 to pivot and separate from each other, allowing the micro drill bit A to move between the clamping plates 3314 and 3324. When the slider 322 moves downward, the second pusher 3222 leaves the space between the first transmission member 334 and the second transmission member 335. Therefore, the columns 3315 and 3325 are pulled by the contraction force of the spring 336 to pull the first support member 331 and the second support member 332, causing the clamping plates 3314 and 3324 to come together and assist in clamping the front end of the micro drill bit A.

[0072] Since each clamping piece 3314 and 3324 clamps the front end of the micro drill bit A, it can counteract the sway caused by the clamping part 22 driving the micro drill bit A to rotate, so that the micro drill bit can maintain stability in grinding assembly 11, and the user can adjust the speed of the second power source 31 according to the sway amplitude when the micro drill bit A rotates.

[0073] The above detailed description is a specific description of a feasible embodiment of the present invention. However, the embodiment is not intended to limit the patent scope of the present invention. All equivalent implementations or modifications that do not depart from the spirit of the present invention should be included in the patent scope of the present invention.
