Description

Technical Field

[0001] This invention relates to the field of surface acoustic wave filter packaging frame technology, specifically to milling equipment for surface acoustic wave filter packaging frames. Background Technology

[0002] A surface acoustic wave (SAW) filter is a radio frequency (RF) filter based on piezoelectric materials. It achieves signal filtering by utilizing the physical properties of surface acoustic waves propagating on the crystal surface. The SAW filter's packaging frame is a key structure that protects its core functional area and enables electrical connections. Because it needs to achieve electrical connections between the chip and external circuits, it requires milling the cavity using SAW filter packaging frame milling equipment to facilitate chip mounting on the SAW filter's packaging frame.

[0003] In existing technologies, after the surface acoustic wave (SAW) filter packaging frame is milled, the placement recesses after milling need to be polished to ensure that the chip is easy to place and to prevent burrs from affecting the chip. Since the milling and polishing of the SAW filter packaging frame are usually not performed simultaneously, the SAW filter packaging frame needs to be transferred to a polishing area after milling, which is too time-consuming and reduces production efficiency. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. When the circular grinding block rotates via the rotating rod, it drives the first ring rack to rotate, which in turn drives the second gear to rotate, which in turn drives the second ring rack to rotate, thus causing the circular grinding block to rotate. The circular and ring grinding blocks rotate in opposite directions, allowing the milling cutter body to mill layer by layer. Simultaneously, the circular grinding block slowly descends, first grinding the top of the groove in a forward rotation. As it descends, it grinds the lower portion of the groove, while the circular grinding block grinds the top of the groove in a reverse rotation. This forward and reverse grinding process makes it easier to remove burrs from the groove, improving grinding efficiency, reducing grinding time, and further enhancing both grinding efficiency and effect.

[0017] 2. During milling, the milling cutter body rotates, driving the ring rack five to rotate via the connecting plate. Because the ring rack five meshes with a set of gears five, the rotation of the ring rack five drives the gears five to rotate, which in turn drives the rotating rod five and the suction fan blades to rotate, generating suction. This causes the debris generated during milling to be caught by the suction shell and then drawn into the square shell for collection. This ensures that the debris is collected and processed, preventing it from affecting subsequent grinding. Furthermore, debris located within the surface acoustic wave (SAW) filter packaging frame can easily affect subsequent milling processes. This debris handling solves the problem of debris causing defects in the milling of the SAW filter packaging frame, thus improving the yield rate of the milled SAW filter packaging frame.

[0030] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] Please see Figures 1-10As shown, a surface acoustic wave (SAW) filter encapsulation frame milling machine includes a frame 1; a mobile device 2 is mounted on the top of the inner wall of the frame 1; a worktable 3 is mounted on the bottom of the inner wall of the frame 1; a fixing mechanism is mounted on the top of the outer wall of the worktable 3; a lifting device 4 is mounted on the bottom of the outer wall of the mobile device 2; a milling device 5 is mounted on the bottom of the outer wall of the lifting device 4; a milling cutter body 66 is mounted on the output end of the milling device 5; a sliding plate 6 is fixedly connected to one side of the outer wall of the milling device 5; a slider 7 is mounted on the bottom of the outer wall of the sliding plate 6; a rotating rod 8 is rotatably connected to the bottom of the outer wall of the slider 7; a circular grinding block 9 is fixedly connected to the bottom of the outer wall of the rotating rod 8; sprockets 10 are fixedly connected to the outer walls of both the rotating rod 8 and the milling cutter body 66, and a pair of sprockets 10 are connected by a chain 11. By placing the SAW filter encapsulation frame on the worktable 3 and fixing it with the fixing mechanism, the mobile device 2 moves to a designated position through the control system, and the lifting device 4 drives the milling device. The milling machine 5 descends, causing the milling cutter body 66 to move and mill the surface acoustic wave filter (SAW) filter packaging frame. The milling cutter body 66 mills the SAW filter packaging frame layer by layer. When one placement recess is completed, the milling cutter body 66 processes the second placement recess. Because the placement grooves on the SAW filter packaging frame are mostly regularly arranged, when the milling cutter body 66 processes the second placement groove, it drives the rotating rod 8 to rotate via the sprocket 10 and chain 11. The rotating rod 8 then drives the circular grinding block 9 to rotate, allowing the circular grinding block 9 to grind the first placement groove. This allows the device to simultaneously mill the placement grooves of the SAW filter packaging frame and grind the placement grooves, saving the time required for grinding the placement grooves and improving the overall production efficiency of the SAW filter packaging frame milling process.

[0033] The top of the outer wall of slider 7 is slidably connected to the bottom of the outer wall of slide plate 6; the bottom of the outer wall of slide plate 6 is rotatably connected to threaded rod 19 via block 1, and one end of the outer wall of threaded rod 19 passes through slider 7; threaded rod 19 is threadedly connected to slider 7; a square plate 20 is fixedly connected to one side of the outer wall of slide plate 6; a square block 21 is fixedly connected to one side of the outer wall of slide plate 6 via a spring, and the top of the outer wall of square block 21 is slidably connected to the bottom of the outer wall of square plate 20; a rotating rod 22 is rotatably connected to the bottom of the outer wall of square block 21; a gear 23 is rotatably connected to the bottom of the outer wall of rotating rod 22, and gear 23 is connected to a pair of sprockets 10 via chain 11. By rotating threaded rod 19, threaded rod 19... The rotation of the slider 7 causes the slider 7 to move, which in turn causes the rotating rod 8 and the circular grinding block 9 to move. This allows the position of the circular grinding block 9 and the milling cutter body 66 to be adjusted according to the processing requirements of the placement groove of the surface acoustic wave filter packaging frame. This facilitates the milling processing of various types of surface acoustic wave filter packaging frames. When the rotating rod 8 moves, since gear 23 and a pair of sprockets 10 are connected by a chain 11, the sprockets 10 on the rotating rod 8 move. The spring will extend and retract, causing the square block 21, the rotating rod, and gear 23 to move, thereby adjusting the tension of the chain 11. This allows the rotating rod 8 and the circular grinding block 9 to operate normally without the need to replace the chain 11, making the device more intelligent, convenient, and practical.

[0034] An electric telescopic rod 28 is fixedly connected to one side of the outer wall of the milling machine 5 via a block five; an adjusting block 29 is fixedly connected to the bottom end of the outer wall of the electric telescopic rod 28; a suction shell 30 is fixedly connected to one side of the outer wall of the adjusting block 29; a set of square shells 31 are fixedly connected to the outer wall of the suction shell 30, and all of the square shells 31 are connected to the suction shell 30; a rotating rod 32 is rotatably connected to one side of the outer wall of the square shell 31, and one end of the outer wall of the rotating rod 32 extends into the square shell 31; a set of suction fan blades are fixedly connected to the outer wall of the end of the rotating rod 32 located inside the square shell 31. 33; A filter screen 34 is fixedly connected to the inner wall of the square shell 31; A gear 35 is fixedly connected to one end of the rotating rod 32 located on the outer wall of the square shell 31; A connecting plate 36 is slidably connected to one side of the outer wall of the milling cutter body 66; A ring rack 37 is fixedly connected to the bottom end of the outer wall of the connecting plate 36, and the ring rack 37 meshes with a set of gears 35; Auxiliary blocks 38 are fixedly connected to one side of the outer wall of a set of square shells 31, and one side of the outer wall of a set of auxiliary blocks 38 is slidably connected to the inner wall of the ring rack 37. When the milling cutter body 66 rotates into... During milling, the milling cutter body 66 drives the ring rack 37 to rotate via the connecting plate 36. Because the ring rack 37 meshes with a set of gears 35, the rotation of the ring rack 37 drives the gears 35 to rotate, which in turn drives the rotating rod 32 and the suction fan blades 33 to rotate, generating suction. This causes the chips and other debris generated during milling to be caught by the suction housing 30 and then drawn into the square housing 31 for collection. This ensures that the chips and other debris are collected and processed, preventing them from affecting subsequent operations. The continuous grinding process, and the fact that the debris located in the surface acoustic wave filter packaging frame can easily affect the subsequent milling process, makes the debris handling a solution to the problem that debris can easily cause defects in the milling process of the surface acoustic wave filter packaging frame, thereby improving the yield of the milling process of the surface acoustic wave filter packaging frame. In addition, the position of the suction shell 30 can be controlled by the electric telescopic rod 28, so that the suction shell 30 can be cleaned up in a better position. And the filter screen 34 will block the debris, so that the debris will not easily affect the operation of the suction fan blade 33.

[0035] The fixing mechanism includes clamping plates 12; a groove 13 is provided at the top of the outer wall of the worktable 3; the outer walls of a pair of clamping plates 12 are slidably connected to the inner wall of the groove 13; a double-threaded rod 14 is rotatably connected to one side of the inner wall of the groove 13, and one end of the outer wall of the double-threaded rod 14 passes through the worktable 3 and the pair of clamping plates 12; the double-threaded rod 14 is threadedly connected to the pair of clamping plates 12; fixed plates 15 are hinged to opposite sides of the outer walls of the pair of clamping plates 12; torsion springs are provided at the junctions of the two pairs of fixed plates 15 and the pair of clamping plates 12, and the two pairs of fixed plates 15 are symmetrical about the center line of the worktable 3. By rotating the double-threaded rod 14, the clamping plates 12 can be connected to the worktable 3. The rotation of the threaded rod 14 causes a pair of clamping plates 12 to move towards the center, thereby clamping and fixing the surface acoustic wave filter packaging frame. When the clamping plates 12 fix the surface acoustic wave filter packaging frame, the two pairs of fixing plates 15 also abut against the outer wall of the surface acoustic wave filter packaging frame. At this time, the fixing plates 15 compress the surface acoustic wave filter packaging frame through the force of the torsion spring, making the surface acoustic wave filter packaging frame more stable. Furthermore, since the two pairs of fixing plates 15 and the pair of clamping plates 12 respectively form two triangular shapes, the stability of the fixation is further improved.

[0036] A collecting shell 39 is provided at the bottom of the outer wall of the square shell 31; a square through groove 40 is provided at the bottom of the inner wall of the square shell 31, and the square through groove 40 is connected to the collecting shell 39; a strip block 41 is fixedly connected to one side of the outer wall of the square shell 31; a bolt 42 is threadedly connected to one side of the outer wall of the strip block 41, and one end of the outer wall of the bolt 42 passes through the strip block 41; a threaded groove 43 is provided on one side of the outer wall of the collecting shell 39, and the bolt 42 matches the threaded groove 43. When debris enters the square shell 31, the debris will pass through the square through groove 49. The debris is stored in the collection shell 39 through the channel 40. The vibration generated by the operation of the equipment will not cause the debris to move out of the square shell 31. On the contrary, it will make the debris easier to enter the collection shell 39 and be collected. Once the debris enters the collection shell 39, it is not easy to move out due to gravity. This makes the debris easier to collect and allows the device to collect more debris. When the debris needs to be recycled, the bolt 42 can be rotated to move the bolt 42 out of the threaded groove 43 and release the fixation.

[0037] A circular grinding block 9 has an annular grinding block 24 rotatably connected to its outer top; an annular rack 25 is fixedly connected to its outer top; an annular rack 26 is fixedly connected to the inner side wall of the annular grinding block 24; a gear 27 is rotatably connected to the bottom of the outer wall of the adjusting plate 18 via a connecting rod; the annular rack 25, gear 27, and annular rack 26 mesh with each other. When the circular grinding block 9 rotates via the rotating rod 8, the circular grinding block 9 drives the annular rack 25 to rotate, the rotation of the annular rack 25 drives the gear 27 to rotate, and the rotation of the gear 27 drives the annular rack 26 to rotate, thereby driving the annular grinding block 24 to rotate. 4. The annular grinding block 24 and the circular grinding block 9 rotate in opposite directions, so that the milling cutter body 66 performs milling layer by layer. At the same time, the annular grinding block 24 and the circular grinding block 9 will slowly descend. The circular grinding block 9 first performs forward grinding on the top of the placement groove. When descending, the circular grinding block 9 grinds the lower part, while the annular grinding block 24 performs reverse grinding on the top of the placement groove. Through forward and reverse grinding, the device can more easily grind and clean the burrs in the placement groove, making the grinding efficiency of the device better, thereby reducing the grinding time required and further improving the grinding efficiency and grinding effect.

[0038] An annular plate 44 is fixedly connected to the top of the inner wall of the connecting plate 36 via a square plate 8; an auxiliary shell 45 is fixedly connected to the outer wall of the annular plate 44; the auxiliary shell 45 matches the inner wall of the suction shell 30; the auxiliary shell 45 matches the square shell 31; a triangular block 46 is fixedly connected to one side of the inner wall of the suction shell 30, and the bottom end of the outer wall of the triangular block 46 is in contact with the bottom end of the inner wall of the suction shell 30; an inclined plate 47 is fixedly connected to one side of the outer wall of the triangular block 46. When the connecting plate 36 rotates, the connecting plate 36 drives the annular plate 44 via the square plate 8. When the shaped plate 44 rotates, the annular plate 44 drives a set of auxiliary shells 45 to rotate. When the auxiliary plate rotates, it can scrape and collect the debris on the inner wall of the suction shell 30. Because the suction size and inlet of the inner wall of the suction shell 30 are different, the debris that cannot be sucked into the square shell 31 located on the inner wall of the suction shell 30 is scraped to the opening of the square shell 31 by the scraping of the auxiliary shell 45, and then sucked in and collected. This allows more debris to be collected and further improves the debris collection effect of this device.

[0039] The rotating rod 8 includes a circular shell 801 and a circular rod 802; the outer wall of the circular rod 802 is slidably connected to the inner wall of the circular shell 801; a motor 16 is fixedly connected to one side of the outer wall of the slider 7 via a fixing block; the output end of the motor 16 is provided with a threaded shaft 17; an adjusting plate 18 is threadedly connected to the outer wall of the threaded shaft 17, and the adjusting plate 18 is rotatably connected to the circular rod 802. The motor 16 drives the threaded shaft 17 to rotate, causing the rotation of the threaded shaft 17 to drive the adjusting plate 18 to move up and down, which in turn causes the adjusting plate 18 to drive the circular rod 802 and the circular grinding block 9 to move up and down. When the milling cutter body 66 processes the first placement groove, the motor 16 drives the circular grinding block 9 to move upward, so that the circular grinding block 9 does not contact the surface acoustic wave filter packaging frame, thus making it less likely to damage the surface acoustic wave filter packaging frame. When the milling cutter body 66 processes the second placement groove, the motor 16 drives the circular grinding block 9 to move to a suitable position, so that the surface acoustic wave filter packaging frame is milled and ground at the same time, thereby saving a lot of time, improving production efficiency, and allowing the circular grinding block 9 to perform grinding operations more flexibly.

[0040] Example 2:

[0041] Please see Figures 9-10 As shown, a rotating rod 48 is rotatably connected to one side of the outer wall of the auxiliary shell 45, and one end of the outer wall of the rotating rod 48 extends into the auxiliary shell 45; a spiral blade 49 is fixedly connected to the outer wall of the end of the rotating rod 48 inside the auxiliary shell 45; a gear 50 is fixedly connected to the outer wall of the rotating rod 48 outside the auxiliary shell 45; an annular rack 51 is fixedly connected to the inner wall of the suction shell 30; the annular rack 51 meshes with a set of gears 50; the spiral blade 49 is located below the inclined plate 47. When the auxiliary shell 45 rotates, the auxiliary shell 45 drives the rotating rod 48 and the gear 50 to rotate, because the annular rack 51 meshes with the gear 50. A set of gears 950 mesh with each other, and the ring rack 951 is fixed. When the gears 950 rotate, the ring rack 951 rotates, which in turn drives the rotating rod 948 to rotate. The rotating rod 948 drives the threaded blades to rotate, so that the debris is collected in the auxiliary shell 45 through the triangular block 46 and the inclined plate 47. Through the rotation of the rotating rod 948 and the threaded blades, the debris at the bottom gradually moves upward under the rotation of the threaded blades, which makes it easier for the suction to draw the debris into the square shell 31 and the collection shell 39 for storage. It also makes it less likely that the debris at the bottom of the auxiliary shell 45 will accumulate due to the suction.

[0042] In use, the present invention involves placing the surface acoustic wave (SAW) filter encapsulation frame on the workbench 3, and then rotating the bidirectional threaded rod 14. This rotation causes a pair of clamping plates 12 to move towards the center, thus clamping and fixing the SAW filter encapsulation frame. When the clamping plates 12 have fixed the SAW filter encapsulation frame, two pairs of fixing plates 15 also abut against the outer side wall of the SAW filter encapsulation frame. At this time, the fixing plates 15 compress the SAW filter encapsulation frame through the force of the torsion spring, making the SAW filter encapsulation frame more stable. Furthermore, since the two pairs of fixing plates 15 and the pair of clamping plates 12 each form two triangular shapes, the stability of the fixation is further improved.

[0043] After the surface acoustic wave (SAW) filter encapsulation frame is fixed, it is moved to the designated position by the mobile device 2 through the control system. At this time, the lifting device 4 drives the milling device 5 to descend, causing the milling device 5 to drive the milling cutter body 66 to run, so that the milling cutter body 66 can mill the SAW filter encapsulation frame. At this time, the milling cutter body 66 mills the SAW filter encapsulation frame layer by layer. When one placement recess is completed, when the milling cutter body 66 processes the second placement recess, since the placement grooves on the SAW filter encapsulation frame are mostly set in a regular pattern, when the milling cutter body 66 processes the second placement groove, the milling cutter body 66 drives the rotating rod 8 to rotate through the sprocket 10 and chain 11, so that the rotating rod 8 drives the circular grinding block 9 to rotate, so that the circular grinding block 9 grinds the first placement groove. Thus, this device can mill the placement grooves of the SAW filter encapsulation frame and grind the placement grooves at the same time, thereby saving the time required for grinding the placement grooves and improving the overall production efficiency of the milling of the SAW filter encapsulation frame.

[0044] The motor 16 drives the threaded shaft 17 to rotate, which in turn moves the adjusting plate 18 up and down. The adjusting plate 18 then moves the circular rod 802 and the circular grinding block 9 up and down. When the milling cutter body 66 is machining the first placement groove, the motor 16 moves the circular grinding block 9 upward, preventing it from contacting the surface acoustic wave filter (SAW) filter encapsulation frame and thus minimizing damage. When the milling cutter body 66 is machining the second placement groove, the motor 16 moves the circular grinding block 9 to the appropriate position, allowing the SAW filter encapsulation frame to be milled and ground simultaneously. This saves a significant amount of time, improves production efficiency, and allows the circular grinding block 9 to perform grinding operations more flexibly.

[0045] By rotating the threaded rod 19, the slider 7 moves, which in turn moves the rotating rod 8 and the circular grinding block 9. This allows the position of the circular grinding block 9 and the milling cutter body 66 to be adjusted according to the processing requirements of the placement groove of the surface acoustic wave filter packaging frame. This facilitates milling processing of various types of surface acoustic wave filter packaging frames. When the rotating rod 8 moves, since gear 23 and a pair of sprockets 10 are connected by a chain 11, the sprockets 10 on the rotating rod 8 move. The spring will extend and retract, causing the square block 21, the rotating rod, and gear 23 to move, thereby adjusting the tension of the chain 11. This allows the rotating rod 8 and the circular grinding block 9 to operate normally without the need to replace the chain 11, making the device more intelligent, convenient, and practical.

[0046] When the circular grinding block 9 rotates via the rotating rod 8, it drives the annular rack 25 to rotate. The rotation of the annular rack 25 drives the gear 27 to rotate, and the rotation of the gear 27 drives the annular rack 26 to rotate, thereby driving the annular grinding block 24 to rotate. The annular grinding block 24 and the circular grinding block 9 rotate in opposite directions, so that the milling cutter body 66 performs milling layer by layer. The annular grinding block 24 and the circular grinding block 9 will also slowly descend. The circular grinding block 9 first performs forward grinding on the top of the placement groove. When descending, the circular grinding block 9 grinds the lower part, while the annular grinding block 24 performs reverse grinding on the top of the placement groove. Through forward and reverse grinding, the device can more easily grind and clean the burrs in the placement groove, making the grinding efficiency of the device better, thereby reducing the grinding time and further improving the grinding efficiency and grinding effect.

[0047] When the milling cutter body 66 rotates to perform milling, the milling cutter body 66 drives the annular rack 37 to rotate via the connecting plate 36. Because the ring rack 37 meshes with a set of gears 35, the rotation of the ring rack 37 drives the gears 35 to rotate, which in turn drives the rotating rod 32 and the suction fan blades 33 to rotate, generating suction. When the milling cutter body 66 produces debris, it is blocked by the suction shell 30 and then sucked into the square shell 31 for collection. This ensures that the debris is collected and processed, preventing it from affecting subsequent grinding. Debris in the surface acoustic wave filter packaging frame can also easily affect subsequent milling. This debris processing solves the problem that debris can easily cause defects in the milling of the surface acoustic wave filter packaging frame, improving the yield of the milling of the surface acoustic wave filter packaging frame. Furthermore, the position of the suction shell 30 can be controlled by the electric telescopic rod 28, allowing the suction shell 30 to perform debris cleaning in a better position. The filter screen 34 also blocks debris, preventing it from affecting the operation of the suction fan blades 33.

[0048] When debris enters the square shell 31, it is collected in the collection shell 39 through the square through groove 40. The vibration generated by the operation of the equipment will not cause the debris to move out of the square shell 31, but will make it easier for the debris to enter the collection shell 39 for collection. Once the debris enters the collection shell 39, it is not easy to move out due to gravity, making it easier to collect. This also allows the device to collect more debris. When it is necessary to recycle the debris, the bolt 42 is rotated to move the bolt 42 out of the thread groove 43 and the fixation is released.

[0049] When the connecting plate 36 rotates, it drives the annular plate 44 to rotate via the square plate 8. The annular plate 44 drives a set of auxiliary shells 45 to rotate. When the auxiliary plate rotates, it can scrape and collect the debris on the inner wall of the suction shell 30. Because the suction size and inlet of the inner wall of the suction shell 30 are different, the debris that cannot be sucked into the square shell 31 from the inner wall of the suction shell 30 is scraped to the opening of the square shell 31 by the scraping of the auxiliary shell 45, and then sucked in and collected. This results in more debris being collected and further improves the debris collection effect of this device.

[0050] When the auxiliary shell 45 rotates, it drives the rotating rod 9 48 and the gear 9 50 to rotate. Since the annular rack 9 51 meshes with a set of gears 9 50 and the annular rack 9 51 is in a fixed state, when the gear 9 50 rotates, the annular rack 9 51 rotates, thereby driving the rotating rod 9 48 to rotate. The rotating rod 9 48 drives the threaded blades to rotate, so that the debris is collected by the auxiliary shell 45 through the triangular block 46 and the inclined plate 47. Through the rotation of the rotating rod 9 48 and the threaded blades, the debris at the bottom gradually moves upward under the rotation of the threaded blades, which makes it easier for the suction to draw the debris into the square shell 31 and the collection shell 39 for storage. It also makes it less likely that the debris at the bottom of the auxiliary shell 45 will accumulate due to the suction.
