A piezoelectric ceramic component packaging device

Abstract

This invention discloses a piezoelectric ceramic component packaging device, relating to the field of piezoelectric ceramic component packaging technology. It includes a fixing mechanism comprising a base plate with two sets of auxiliary plates fixedly connected to its top. A material injection mechanism is disposed above the base plate. The invention uses a main hydraulic rod to push a front plate, connecting the inflation pipe and air outlet to the exhaust pipe and suction pipe. This allows an air pump to extract air from the negative pressure chamber, creating a negative pressure environment. When resin is poured into the mold, air bubbles within the resin are expelled by the negative pressure, allowing the resin inside the mold to better encapsulate the piezoelectric ceramic component. Furthermore, the negative pressure inside the chamber promotes resin flow towards the injection port, increasing the resin pouring speed. During the air pump's extraction of air from the negative pressure chamber, this air is injected into an air bladder, clamping and fixing the mold to prevent displacement during the packaging process.

Description

Technical Field

[0001] This invention relates to the field of piezoelectric ceramic component packaging technology, specifically to a piezoelectric ceramic component packaging device. Background Technology

[0002] Piezoelectric ceramics are functional ceramic materials that can convert mechanical energy and electrical energy into each other—the piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric and elastic properties, and have been widely used in medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezoelectric ceramics are mainly used to manufacture ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic frequency discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optic devices, ignition and detonation devices, and piezoelectric gyroscopes, etc. Of course, epoxy resin encapsulation is essential to the production process of piezoelectric ceramics.

[0003] Existing semiconductor packaging technology achieves the packaging effect of piezoelectric ceramic components by pouring resin into a mold and mixing the resin in a mixing tank, followed by vacuuming the mixing tank to remove air bubbles. However, during the pouring process into the mold, some air bubbles are still mixed in with the resin, resulting in a large number of air bubbles on the outside of the packaged piezoelectric ceramic components, which affects the packaging quality. To address this, a packaging device for piezoelectric ceramic components is proposed. Summary of the Invention

[0017] In summary, the present invention has the following main beneficial effects:

[0018] 1. This invention uses a main hydraulic rod to push the front plate, connecting the inflation pipe and air outlet to the exhaust pipe and suction pipe. This allows the air pump to extract air from the negative pressure chamber, creating a negative pressure environment inside. When resin is poured into the mold, air bubbles inside the resin are expelled by the negative pressure, allowing the resin inside the mold to better encapsulate the piezoelectric ceramic components. The negative pressure inside the chamber also promotes the flow of resin into the injection port, increasing the resin pouring speed. During the process of the air pump extracting air from the negative pressure chamber, this air is injected into the airbag, thereby clamping and fixing the mold and preventing the mold position from shifting during the encapsulation process.

[0019] 2. This invention uses the main hydraulic rod to push the front plate, causing the rack to slide and thus pushing the rotating arm to flip. During the flipping of the rotating arm, the bracket can also be flipped, allowing the clamp to flip when the bracket is in different positions. This ensures that during the sealing process, the clamp fixes the negative pressure chamber and the top cover, maintaining a sealed state between the top cover and the negative pressure chamber. Furthermore, during the extension and retraction of the main hydraulic rod, the suction pipe and exhaust pipe can be connected or disconnected from the negative pressure chamber, greatly improving the automation level of the entire sealing device and reducing labor costs.

[0020] 3. This invention uses a motor to drive an auger to rotate, which pushes the resin into the discharge pipe. A piston inside the injection head prevents excess resin from flowing out after the discharge pipe separates from the injection port. A heating wire and insulation layer inside the injection head heat the resin upon entry, increasing its fluidity and preventing it from becoming viscous in low-temperature environments. This allows the resin to fill the mold more quickly during encapsulation, improving encapsulation efficiency. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of the present invention will now be described.

[0038] A piezoelectric ceramic component packaging device, such as Figure 1 - Figure 11 As shown, it includes a fixing mechanism 1, which includes a base plate 101. Two sets of sub-plates 102 are fixedly connected to the top of the base plate 101. An injection mechanism 3 is provided above the base plate 101. A defoaming mechanism 2 is provided above each set of sub-plates 102.

[0039] The defoaming mechanism 2 includes two sets of negative pressure chambers 201. Multiple pressure frames 202 are fixedly connected to the bottom of the inner wall of each set of negative pressure chambers 201. The side walls of the multiple pressure frames 202 are connected to inflation pipes 203 extending to the outside of the negative pressure chambers 201. One end of the inflation pipe 203 outside the pressure frame 202 is connected to an air inlet 204. The side wall of the negative pressure chamber 201 is connected to an air outlet 205 located next to the inflation pipe 203. A set of limiting devices is fitted inside each of the multiple pressure frames 202. The inner walls of the multiple pressure frames 202 are respectively connected to multiple airbags 207. Each set of limiting frames 206 is respectively sleeved on the outside of the multiple airbags 207. The top of the negative pressure chamber 201 is provided with a top cover 208. The top of the top cover 208 is provided with a material injection port 209. The outer wall of the air outlet 205 is provided with a suction pipe 215. The outer wall of the air inlet 204 is provided with an exhaust pipe 216. The side walls of the suction pipe 215 and the exhaust pipe 216 are connected to an air pump 214.

[0040] Each set of sub-plates 102 has a set of first rotating shafts 107 rotatably connected to its inner wall. Each set of first rotating shafts 107 has a set of rotating arms 109 fixedly fitted at both ends of its outer wall. Each set of rotating arms 109 has a set of second rotating shafts 110 rotatably fitted at its ends. A bracket 111 is fixedly connected between the two sets of second rotating shafts 110. Each set of brackets 111 has a set of negative pressure chambers 201 fitted on its inner wall.

[0041] The top end of the inflation tube 203 is connected to a pressure relief port 210. A silicone sheet 211 is fitted on the inner wall of the pressure relief port 210. The silicone sheet 211 is attached to the connection between the pressure relief port 210 and the suction tube 215. A spring sheet 213 is fixedly connected to the inner wall of the pressure relief port 210. A pressure ring 212 is fixedly connected to the bottom end of the spring sheet 213. The pressure ring 212 is attached to the top end of the silicone sheet 211.

[0042] The piezoelectric ceramic component is placed inside the mold, and then the mold is placed inside the limiting frame 206, so that multiple airbags 207 surround the outside of the mold. The rotation of the first rotating shaft 107 drives the rotating arm 109 to rotate. During the rotation of the rotating arm 109, the second rotating shaft 110 rotates, causing the bracket 111 to rotate with the second rotating shaft 110, thereby causing the negative pressure chamber 201 to rotate. After the negative pressure chamber 201 rotates to below the discharge pipe 311, the suction pipe 215 is sleeved on the outer wall of the air outlet 205, and the exhaust pipe 216 is sleeved on the outer wall of the air inlet 204. Then the airbags 207 draw the air inside the negative pressure chamber 201 into the suction pipe 215. 5. Then, the air enters the pressure frame 202 through the inflation tube 203, causing the airbag 207 to inflate and expand, thus making the airbag 207 fit against the outer wall of the mold and fixing the mold in place. During the inflation process of the airbag 207, when the pressure is too high, the silicone sheet 211 is subjected to greater pressure, causing the silicone sheet 211 to bend upward, thereby pushing the pressure ring 212 and causing the spring sheet 213 to bend. At this time, the excess air will be discharged through the pressure relief port 210. After the pressure drops to a reasonable range, the spring sheet 213 rebounds, causing the pressure ring 212 to press the silicone sheet 211 down and reset, thereby sealing the inflation tube 203.

[0043] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The top of the base plate 101 is fixedly connected to a main hydraulic rod 103 located between two sets of auxiliary plates 102. The end of the main hydraulic rod 103 is fixedly connected to a front plate 104. The side wall of the front plate 104 is fixedly connected to the side wall of the air pump 214. The suction pipe 215 and the exhaust pipe 216 are fixedly connected to the top of the front plate 104. Multiple sets of sliding rods 105 are fixedly connected to the side wall of the front plate 104. The sliding rods 105 are slidably connected to the bottom of the inner wall of the auxiliary plate 102. Each set of sliding rods 105 is fixedly connected to a set of racks 106 at its end. Two sets of gears 108 are fixedly sleeved on the outer wall of each set of first rotating shafts 107. Each set of gears 108 meshes with a set of racks 106. A set of first synchronous pulleys 112 are rotatably sleeved at both ends of the first rotating shaft 107. The first synchronous pulley 112 is fixedly connected to the inner wall of the auxiliary plate 102. A set of second synchronous pulleys 113 are fixedly sleeved at the end of each set of second rotating shafts 110. A synchronous belt 114 is sleeved on the outer wall of the first synchronous pulley 112 and the second synchronous pulley 113 located on the same side. A set of clamps 115 are hinged to both sides of each set of brackets 111. A set of sliding frames 116 are fixedly connected to the side wall of each set of clamps 115. A set of top rods 117 are slidably sleeved on the inner wall of each set of sliding frames 116. A slider 118 is fixedly connected to both ends of the top rod 117. The slider 118 is slidably connected to the inner wall of the bracket 111. Multiple sets of fixing springs 119 are fixedly connected to the inner wall of the bracket 111. The bottom ends of the multiple sets of fixing springs 119 are fixedly connected to the side walls of the two sets of sliders 118.

[0044] The retraction of the main hydraulic rod 103 causes the front plate 104 to slide. The front plate 104 pushes the rack 106 to slide via the slide rod 105, thereby causing the gear 108 to rotate. This causes the gear 108 to drive the first rotating shaft 107 to rotate. Since the first synchronous pulley 112 is sleeved on the outer wall of the first rotating shaft 107, but is fixedly connected to the inner wall of the auxiliary plate 102, the first synchronous pulley 112 will not be driven to rotate by the first rotating shaft 107. The second rotating shaft 110 is rotatably connected to the rotating arm 109, while the second rotating shaft 110 is fixedly connected to the second synchronous pulley 113. The second rotating shaft 110 is rotated... During the rotation process driven by arm 109, since the outer walls of the first synchronous pulley 112 and the second synchronous pulley 113 are fitted with the same set of synchronous belts 114, the second rotating shaft 110 rotates while the arm 109 drives the second rotating shaft 110 to rotate. This causes the second rotating shaft 110 and the arm 109 to rotate, keeping the bracket 111 and the sub-plate 102 parallel. After the arm 109 rotates 180 degrees, the bracket 111 rotates the slider 118 during the rotation process, causing the slider 118 to separate from the sub-plate 102. At this time, the fixing spring 119 rebounds and pushes the slider 118 downward, thereby causing the slider 118 to drive the push rod 117 to move downward. 7. During the downward movement, the sliding frame 116 is pulled, causing the clamp 115 to flip, thereby pressing the upper cover 208 against the top of the negative pressure chamber 201. This causes the bracket 111 to flip from one end of the sub-plate 102 to the other end. At this time, the bottom end of the bracket 111 is in contact with the inner wall of the sub-plate 102, but the slider 118 does not contact the sub-plate 102. Therefore, during the pouring process, the upper cover 208 is always pressed against the top of the negative pressure chamber 201. After the resin is poured, the main hydraulic rod 103 extends, causing the front plate 104 to slide in the opposite direction. At this time, the rack 106 slides in the opposite direction, thereby causing the gear 108 to rotate in the opposite direction, causing the rotating arm 109 to rotate 180 degrees in the opposite direction. This causes the rotating arm 109 to flip and reset. During this process, the bracket 111 flips from one end of the sub-plate 102 to the other end of the sub-plate 102, causing the slider 118 to contact the reset inner wall, thereby pushing the slider 118 to slide upward, causing the fixing spring 119 to be compressed. At this time, the slider 118 pushes the push rod 117 to slide upward, causing the push rod 117 to push the sliding frame 116, thereby causing the chuck 115 to flip, causing the chuck 115 to separate from the upper cover 208. Then the upper cover 208 can be picked up, and the mold filled with resin inside the limiting frame 206 can be taken out. Then the mold containing the unencapsulated piezoelectric ceramic components can be placed inside the limiting frame 206.

[0045] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 11The injection mechanism 3 includes a raw material tank 301, which is fixedly connected to the top of the base plate 101 and located above the defoaming mechanism 2. The bottom of the raw material tank 301 is connected to an injection head 302. An insulation layer 303 is fixedly sleeved on the inner wall of the injection head 302. A heating wire 304 located inside the fixed sleeve is fixedly connected to the inner wall of the injection head 302. An auger 305 is rotatably connected to the inner wall of the injection head 302. A motor 306 is fixedly connected to the side wall of the injection head 302, and the output end of the motor 306 is fixedly connected to the end of the auger 305. A piston 308 is slidably sleeved on the inner wall of the injection head 302. A return spring 309 is fixedly connected to the side wall of the piston 308. The end of the return spring 309 is fixedly connected to the inner wall of the injection head 302. The bottom end of the injection head 302 is connected to a distribution pipe 307. The bottom end of the distribution pipe 307 is connected to two sets of hoses 312. The ends of the two sets of hoses 312 are respectively connected to a set of discharge pipes 311. The side wall of each set of discharge pipes 311 is fixedly connected to two sets of second hydraulic rods 310. The bottom end of the second hydraulic rod 310 is fixedly connected to the top end of the sub-plate 102.

[0046] By adding the mixed resin into the raw material tank 301, the bracket 111 rotates the negative pressure chamber to below the discharge pipe 311. The second hydraulic rod 310 then lowers the discharge pipe 311, inserting it into the injection port 209, thus creating a sealed environment inside the negative pressure chamber 201. Next, the motor 306 drives the auger 305 to rotate, pushing the resin and causing it to push against the piston 308. The piston 308 slides inside the injection head 302, compressing the return spring 309. After the piston 308 passes the connection between the injection head 302 and the distribution pipe 307, the resin flows into the distribution pipe 307 and then into the two discharge pipes 311 via two sets of hoses 312. This process is completed after the resin infusion is finished. The motor 306 stops rotating, and at this time the second hydraulic rod 310 pushes the discharge pipe 311 upward, thereby separating the discharge pipe 311 from the injection port 209, and leaving space for the bracket 111 to flip, so as to avoid obstruction between the upper cover 208 and the discharge pipe during the process of the bracket 111 driving the negative pressure chamber 201 to flip. After the discharge pipe 311 separates from the injection port 209, the return spring 309 rebounds and pushes the piston 308 to reset, so that the piston 308 blocks the injection head 302, preventing excess resin from flowing into the distribution pipe 307. The injection head 302 is equipped with an electric heating wire 304 and a heat insulation layer 303, so that the resin is heated by the electric heating wire 304 after entering the injection head 302, thereby improving the fluidity of the resin.

[0047] In use, the main hydraulic rod 103 pushes the front plate 104, connecting the inflation pipe 203 and the air outlet 205 to the exhaust pipe 216 and the suction pipe 215. This allows the air pump 214 to extract air from the negative pressure chamber 201, creating a negative pressure environment inside the chamber. This negative pressure removes air bubbles from the resin after it is poured into the mold, allowing the resin to better encapsulate the piezoelectric ceramic components. The negative pressure inside the chamber also promotes the flow of resin into the injection port 209, increasing the resin pouring speed. During the process of the air pump 214 extracting air from the negative pressure chamber 201, this air is injected into the airbag 207 to clamp and fix the mold, preventing the mold from shifting during the encapsulation process. Any parts of this device not described herein are the same as or can be implemented using existing technologies.
