Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a drill needle grinding mechanism. Background Art
[0002] PCB, also known as printed circuit board or printed circuit board, is generally made of several layers of resin materials bonded together, with copper foil wiring inside, which can realize the wiring and electrical connection or electrical insulation between various electronic components such as integrated circuits. The production of PCB often requires drilling, so a large number of drill bits are needed. Since the drill bit is prone to wear during use, a collar is generally required to be installed on the drill bit after it is produced for clamping and positioning of the drill bit.
[0003] In the prior art, the production and processing of drill bits are generally carried out by a drill bit grinding mechanism. However, the existing drill bit grinding mechanism does not have the function of automatically putting a collar on the drill bit. Some drill bit grinding equipment has the function of adjusting the collar, but it only adjusts the original collar when recycling the old drill bit that already has a collar for secondary processing, rather than putting a collar on the newly produced drill bit without a collar. Therefore, the collaring of the drill bit often needs to be carried out by another collaring equipment. This production and processing method has the following problems: (1) The production and processing of the drill bit and the collaring of the drill bit need to be carried out by two separate devices, which increases the equipment cost; (2) After the drill bit is produced by the drill bit grinding equipment, it needs to be transported to the collaring equipment for secondary processing before the collaring can be put on, which increases the turnover time and transportation cost.

[0027] like Figure 1 , Figure 2As shown, the utility model provides a drill bit grinding mechanism, including a grinding module 2 and an upper sleeve ring module 1. The grinding module 2 is a prior art structure used for grinding and producing a drill bit 21; the upper sleeve ring module 1 is used to install the sleeve ring 11 onto the drill bit 21 newly produced by the above-mentioned grinding module 2.
[0028] The drill bit grinding mechanism with the above structure is provided with an upper ring module 1 in the drill bit grinding mechanism to increase the function of the upper ring 11, so that the drill bit 21 can be directly provided with the ring 11 during production without being transported to another upper ring equipment for processing, thereby reducing equipment cost and transportation cost.
[0029] In some embodiments, Figure 3 , Figure 4 As shown, the upper ring module 1 includes an upper ring fixing base 12, on which a ring vibration tray 13 is fixedly installed. The ring vibration tray 13 is used to load the rings 11 required in the production process and provide the rings 11 to the ring installation mechanism by vibration; a ring guide plate 14 is connected to the ring outlet of the ring vibration tray 13, and the connection can be a direct connection or an indirect connection through other connecting parts; a first pushing mechanism 15 and a ring guide column 16 are respectively provided at both ends of the ring guide plate 14, the ring guide column 16 is perpendicular to the ring guide plate 14, and a second pushing mechanism 17 is fixed above the ring guide column 16, the first pushing mechanism 15 is used to push the ring 11 on the ring guide plate 14 into the ring guide column 16, and the second pushing mechanism 17 is used to push the ring 11 in the ring guide column 16 downward to install it on the drill needle 21.
[0030] With the drill bit grinding mechanism of the above structure, the ring vibration material tray 13 transports the ring 11 to the ring guide plate 14 by vibration, and then the first pushing mechanism 15 moves to the side of the ring guide column 16 to push the ring 11 located in the ring guide plate 14 into the ring guide column 16, and then the second pushing mechanism 17 moves downward to install the ring 11 located in the ring guide column 16 onto the drill bit 21 located below the ring guide column 16, completing the ring-installing action, realizing automatic ring-installing of the drill bit, and improving production efficiency.
[0031] In some embodiments, the ring guide plate 14 is provided with a first slide groove 141 and a second slide groove 142, and the diameters of the first slide groove 141 and the second slide groove 142 are adapted to the ring 11, so that the ring 11 can move in the slide groove; the first slide groove 141 is located between the first pushing mechanism 15 and the ring guide column 16, connecting the first pushing mechanism 15 and the ring guide column 16; one end of the second slide groove 142 intersects with the first slide groove 141, so that the ring 11 can move from the second slide groove 142 to the first slide groove 141; the other end of the second slide groove 142 is connected to the ring outlet of the ring vibration tray 13, so that the ring 11 coming out of the ring vibration tray 13 can move into the second slide groove 142; the other end of the second slide groove 142 can be directly connected to the ring outlet of the ring vibration tray 13, or it can be indirectly connected through other connecting parts.
[0032] With the drill bit grinding mechanism of the above structure, after the ring 11 is vibrated out by the ring vibration material tray 13, it moves to the second slide groove 142. As more and more rings 11 are vibrated out by the ring vibration material tray 13, the ring 11 gradually moves toward the first slide groove 141. Then the first pushing mechanism 15 moves toward the side of the ring guide column 16 to push the ring 11 in the first slide groove 141 into the ring guide column 16. Then the second pushing mechanism 17 moves downward to install the ring 11 in the ring guide column 16 onto the drill bit 21 below the ring guide column 16 to complete the ring mounting action and improve production efficiency.

[0034] With the drill bit grinding mechanism of the above structure, when the collar 11 moves into the first slide groove 141, the collar pushing cylinder 151 drives the collar pushing plate 152 to move toward the collar guide column 16 in the first slide groove 141, pushing the collar 11 in the first slide groove 141 into the collar guide column 16.
[0035] In some embodiments, the second pushing mechanism 17 includes an upper collar cylinder 171 and a collar push rod 172; the collar push rod 172 is a hollow columnar structure, and the diameter of the collar push rod 172 is adapted to the inner diameter of the collar guide column 16, so that the collar push rod 172 can move up and down on the collar guide column 16; the inner diameter of the collar push rod 172 is adapted to the diameter of the drill needle 21, so that the collar push rod 172 can move downward to install the collar 11 on the drill needle 21.
[0036] With the drill bit grinding mechanism of the above structure, when the collar 11 moves from the first slide groove 141 to the collar guide column 16, the upper collar cylinder 171 drives the collar push rod 172 to move downward in the collar guide column 16, pushing the collar 11 located in the collar guide column 16 downward, thereby installing it on the drill bit 21.
[0037] In some embodiments, a drill bit ejector block 18 is disposed on the upper collar fixing base 12 , and the drill bit ejector block 18 is located below the collar guide column 16 .
[0038] By adopting the drill grinding mechanism of the above structure, the drill push block 18 can push against the drill 21 during the process of putting on the ring to prevent the drill 21 from moving, so that the ring 11 can be installed at a specific position of the drill 21; the height of the drill push block 18 can also be adjusted according to actual production needs to meet customer requirements for drills 21 of different specifications and different depths of rings 11.

[0041] In some embodiments, the multi-station chuck module 3 includes a multi-station chuck fixed base 31, on which a longitudinal linear guide 32 and a slider plate 33 adapted to the linear guide 32 are installed, a chuck base plate 34 perpendicular to the slider plate 33 is arranged on the top of the slider plate 33, a multi-station chuck 35 is arranged on the chuck base plate 34, and the multi-station chuck 35 is provided with at least two drill chucks 351 for clamping the drill bit 21; the multi-station chuck fixed base 31 is also provided with a lifting cylinder 36 for controlling the sliding of the slider plate 33 on the linear guide 32; a rotating motor 37 is arranged at the bottom of the multi-station chuck 35, and the rotating motor 37 can control the rotation of the multi-station chuck 35.
[0042] With the drill bit grinding mechanism of the above structure, under the control of the lifting cylinder 36 and the rotating motor 37, the multi-station chuck module 3 can clamp the drill bit 21 to achieve up and down lifting and rotation between different stations, which can make the production process of the drill bit more efficient.
[0043] In some embodiments, the multi-station chuck module 3 is also provided with at least one clamping cylinder 38, and the clamping cylinder 38 can control the loosening and clamping of the drill chuck 351.

[0044] The drill bit grinding mechanism with the above structure is provided with at least one loosening cylinder 38 that can control the loosening and tightness of the drill bit chuck 351, so that in some workstations where the position of the drill bit 21 needs to be transferred (such as the grinding workstation where the drill bit 21 needs to be transferred to the grinding module), the drill bit 21 can be automatically loosened and clamped, so that the drill bit 21 can be transferred to the relevant workstation for processing and then return to the drill bit chuck 351 to continue the next process.
[0045] In some embodiments, Figure 7 , Figure 8As shown, the multi-station chuck 35 also includes a multi-station chuck body 352 located in the middle, and the drill chuck 351 is distributed on the outer peripheral surface of the multi-station chuck body 352; the drill chuck 351 includes a main chuck 351A and a sub-chuck 351B distributed on the left and right, wherein the main chuck 351A is fixedly connected to the multi-station chuck body 352; in addition, the main chuck 351A is provided with a hollow protrusion 353 on one side close to the sub-chuck 351B, and a bearing 354 is installed in the hollow hole of the protrusion 353; the sub-chuck 351B is provided with A mounting groove 355 for accommodating the protrusion 353 and a stud hole 356 passing through the mounting groove 355 from top to bottom can be embedded therein; the auxiliary chuck 351B is installed on the main chuck 351A by means of a stud 357 passing through the stud hole 356 and the bearing 354; the main chuck 351A and the auxiliary chuck 351B form a drill needle clamping end at one end away from the multi-station chuck body 352, and a spring 358 is installed at one end close to the multi-station chuck body 352, and the two ends of the spring 358 elastically press against the main chuck 351A and the auxiliary chuck 351B respectively.
[0046] The drill bit grinding mechanism adopts the above structure, and the auxiliary chuck 351B is installed on the main chuck 351A through the coordinated installation of the protrusion 353, the bearing 354, the installation groove 355, the stud hole 356, the stud 357, etc., and moves relative to the main chuck 351A with the dots of the bearing 354 and the stud 357 as fixed points, so that the two ends of the auxiliary chuck 351B are close to or away from the main chuck 351A, thereby realizing the opening and clamping of the clamping end of the drill bit; in addition, by installing a spring 358 at both ends that elastically presses against the main chuck 351A and the auxiliary chuck 351B respectively, the elastic force of the spring 358 will keep the clamping end of the drill bit in a clamped state, thereby preventing the drill bit from falling during the rotation between the various workstations.
[0047] In some embodiments, the drill bit grinding mechanism further includes a mechanism base 4, a workstation gantry 5, a pre-grinding cleaning module 6 and / or a post-grinding cleaning module 7 and / or a blade surface detection module 8 and / or an angle detection module 9; the upper collar module 1, the grinding module 2, the multi-station chuck module 3, the pre-grinding cleaning module 6 and / or the post-grinding cleaning module 7 and / or the blade surface detection module 8 and / or the angle detection module 9 are installed on the mechanism base 4 or the workstation gantry (5).

[0054] (6) After the ringing process is completed, the rotary motor 37 rotates to make the drill needle 21 reach the post-grinding cleaning station, and the post-grinding cleaning module 7 fixed on the station gantry 5 cleans the drill needle 21;
[0055] (7) After the post-grinding cleaning process is completed, the rotary motor 37 rotates to return the drill needle 21 to the loading and unloading station. At this time, the ground drill needle 21 can be taken out and another drill needle 21 to be ground can be inserted.
