The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0019] Next, according to the overall structure of the present invention, its embodiments will be described.

[0020] A piezoelectric ceramic component packaging device, as Figure 1 - Figure 11 shown, includes a fixing mechanism 1. The fixing mechanism 1 includes a bottom plate 101. Two groups of auxiliary plates 102 are fixedly connected to the top end of the bottom plate 101. A material injection mechanism 3 is arranged above the bottom plate 101. An air defoaming mechanism 2 is arranged above each group of auxiliary plates 102; The air defoaming mechanism 2 includes two groups of negative pressure chambers 201. A plurality of pressure frames 202 are respectively fixedly connected to the bottom ends of the inner walls of each group of negative pressure chambers 201. A plurality of air charging pipes 203 extending to the outside of the negative pressure chamber 201 are communicated with the side walls of the plurality of pressure frames 202. One end of the air charging pipe 203 located outside the pressure frame 202 is communicated with an air inlet 204. An air outlet 205 located beside the air charging pipe 203 is communicated with the side wall of the negative pressure chamber 201. A group of limiting frames 206 are respectively sleeved inside the plurality of pressure frames 202. A plurality of air bags 207 are respectively communicated with the inner walls of the plurality of pressure frames 202. Each group of limiting frames 206 is respectively sleeved outside the plurality of air bags 207. The top end of the negative pressure chamber 201 is provided with an upper cover 208. A material injection port 209 is arranged through the top end of the upper cover 208. An air extraction pipe 215 is sleeved on the outer wall of the air outlet 205. An exhaust pipe 216 is sleeved on the outer wall of the air inlet 204. An air pump 214 is communicated with the side walls of the air extraction pipe 215 and the exhaust pipe 216; A first rotating shaft 107 is respectively rotatably connected to the inner walls of each group of auxiliary plates 102. A group of rotating arms 109 are respectively fixedly sleeved on the outer walls of each first rotating shaft 107 at positions near both ends. A second rotating shaft 110 is respectively rotatably sleeved at the ends of the two groups of rotating arms 109. A bracket 111 is fixedly connected between the two groups of second rotating shafts 110. A group of negative pressure chambers 201 are respectively sleeved inside the inner walls of each group of brackets 111; The top end of the air charging pipe 203 is communicated with a pressure relief port 210. A silica gel sheet 211 is sleeved on the inner wall of the pressure relief port 210. The silica gel sheet 211 is attached to the connection part between the pressure relief port 210 and the air extraction pipe 215. A spring sheet 213 is fixedly connected to the inner wall of the pressure relief port 210. A pressing ring 212 is fixedly connected to the bottom end of the spring sheet 213. The pressing ring 212 is attached to the top end of the silica gel sheet 211.

[0021] Place the piezoelectric ceramic component inside the mold, and then place the mold inside the limit frame 206, so that multiple airbags 207 surround the outside of the mold. Drive the swing arm 109 to turn by rotating the first rotating shaft 107. During the turning of the swing arm 109, drive the second rotating shaft 110 to turn, so that the bracket 111 turns with the second rotating shaft 110, thereby driving the negative pressure chamber 201 to turn. After the negative pressure chamber 201 turns 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 airbag 207 pumps the air inside the negative pressure chamber 201 into the suction pipe 215, and then through the charging pipe 203, these air enters into the pressure frame 202, making the airbag 207 inflate and expand, so that the airbag 207 fits on the outer wall of the mold, thereby fixing the mold. During the process of inflating the airbag 207, when the pressure is too high, the silica gel sheet 211 is subjected to a large pressure, causing the silica gel sheet 211 to bend upward, thereby pushing and squeezing the pressure ring 212 to make the spring sheet 213 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, making the pressure ring 212 press the silica gel sheet 211 down and reset again, thereby sealing the charging pipe 203.

[0022] Please refer particularly to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7, a main hydraulic rod 103 is fixedly connected to the top end of the bottom plate 101 and is 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 an air pump 214. An air suction pipe 215 and an exhaust pipe 216 are fixedly connected to the top end of the front plate 104. A plurality 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 end inner wall of the auxiliary plates 102. The end of each sliding rod 105 is fixedly connected to a set of racks 106 respectively. Two sets of gears 108 are fixedly sleeved on the outer wall of each first rotating shaft 107 respectively. Each set of gears 108 meshes with a set of racks 106 respectively. A set of first synchronous wheels 112 are rotatably sleeved at both ends of the first rotating shaft 107 respectively. The first synchronous wheels 112 are fixedly connected to the inner wall of the auxiliary plates 102. A set of second synchronous wheels 113 are fixedly sleeved at the end of each second rotating shaft 110 respectively. A synchronous belt 114 is sleeved on the outer walls of the first synchronous wheels 112 and the second synchronous wheels 113 on the same side. A set of chucks 115 are hinged to both sides of each bracket 111 respectively. A set of sliding frames 116 are fixedly connected to the side wall of each chuck 115 respectively. A set of ejector rods 117 are slidably sleeved in the inner wall of each sliding frame 116 respectively. The two ends of the ejector rod 117 are fixedly connected to sliders 118. The sliders 118 are slidably connected to the inner wall of the bracket 111. A plurality of fixing springs 119 are fixedly connected to the inner wall of the bracket 111. The bottom ends of the plurality of fixing springs 119 are fixedly connected to the side walls of the two sliders 118 respectively.

[0023] By contracting the main hydraulic rod 103, the front plate 104 slides. The front plate 104 pushes the rack 106 to slide through the slide rod 105, thereby causing the gear 108 to drive the gear 108 to rotate, causing the gear 108 to drive the first rotating shaft 107 to rotate. And because the first synchronous pulley 112 is sleeved on the outer wall of the first rotating shaft 107, but the first synchronous pulley 112 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, and the connection between the second rotating shaft 110 and the second synchronous pulley 113 is a fixed connection. During the process of the second rotating shaft 110 being driven by the rotating arm 109 to flip, since the same set of synchronous belts 114 is sleeved on the outer walls of the first synchronous pulley 112 and the second synchronous pulley 113, during the process of the rotating arm 109 driving the second rotating shaft 110 to rotate, rotation occurs between the second rotating shaft 110 and the rotating arm 109, so that the bracket 111 and the auxiliary plate 102 always maintain a parallel state. After the rotating arm 109 flips 180 degrees, during the flipping process of the bracket 111, the slider 118 is driven to flip, causing the slider 118 to separate from the auxiliary plate 102. At this time, the fixed spring 119 rebounds and pushes the slider 118 to slide downward, so that the slider 118 drives the ejector rod 117 to move downward. During the downward movement of the ejector rod 117, the sliding frame 116 is pulled, causing the chuck 115 to flip, thereby pressing the upper cover 208 on the top of the negative pressure chamber 201, so that the bracket 111 flips from one end of the auxiliary plate 102 to the other end. At this time, the bottom end of the bracket 111 fits against the inner wall of the auxiliary plate 102, but there is no contact between the slider 118 and the auxiliary plate 102. Therefore, during the pouring process, the upper cover 208 is always pressed on 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 reverse direction. At this time, the rack 106 slides in the reverse direction, thereby causing the gear 108 to rotate in the reverse direction, causing the rotating arm 109 to flip 180 degrees in the reverse direction, causing the rotating arm 109 to flip back to its original position. During this process, the bracket 111 flips from one end of the auxiliary plate 102 to the other end of the auxiliary plate 102, causing the slider 118 to contact the inner wall of the reset position, thereby pushing the slider 118 to slide upward, causing the fixed spring 119 to be compressed. At this time, the slider 118 pushes the ejector rod 117 to slide upward, causing the ejector rod 117 to push the sliding frame 116, thereby driving 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 in 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.

[0024] Please refer particularly to Figure 1 、 Figure 2 、 Figure 3 and Figure 11, the material injection mechanism 3 includes a raw material barrel 301 which is fixedly connected to the top end of the bottom plate 101 and is located above the defoaming mechanism 2. A material injection head 302 is communicated with the bottom end of the raw material barrel 301. A heat preservation layer 303 is fixedly sleeved on the inner wall of the material injection head 302. An electric heating wire 304 located inside the fixed sleeve is fixedly connected to the inner wall of the material injection head 302. An auger 305 is rotatably connected to the inner wall of the material injection head 302. A motor 306 is fixedly connected to the side wall of the material 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 material injection head 302. A return spring 309 is fixedly connected to the side wall of the piston 308, and the end of the return spring 309 is fixedly connected to the inner wall of the material injection head 302. A distribution pipe 307 is communicated with the bottom end of the material injection head 302. Two hoses 312 are communicated with the bottom end of the distribution pipe 307. The ends of the two hoses 312 are respectively communicated with a set of discharge pipes 311. Two second hydraulic rods 310 are respectively fixedly connected to the side walls of each set of discharge pipes 311, and the bottom ends of the second hydraulic rods 310 are fixedly connected to the top end of the auxiliary plate 102.

[0025] By adding the mixed resin into the raw material barrel 301, after the bracket 111 drives the negative pressure chamber to turn over to the lower part of the discharge pipe 311, the second hydraulic rod 310 drives the discharge pipe 311 to descend, so that the discharge pipe 311 is inserted into the injection port 209, thus making the inside of the negative pressure chamber 201 in a closed environment. Then, the motor 306 drives the auger 305 to rotate, thereby pushing the resin, so that the resin pushes the piston 308, making the piston 308 slide inside the material injection head 302 and compress the return spring 309. When the piston 308 slides past the connection between the material injection head 302 and the distribution pipe 307, the resin flows into the distribution pipe 307, and then flows into the two discharge pipes 311 through the two hoses 312 respectively. After the resin perfusion is completed, the motor 306 stops rotating, and at this time, the second hydraulic rod 310 pushes the discharge pipe 311 to rise, so that the discharge pipe 311 is separated from the injection port 209, and space is left for the bracket 111 to turn over, avoiding obstruction between the upper cover 208 and the blanking pipe during the process of the bracket 111 driving the negative pressure chamber 201 to turn over. After the discharge pipe 311 is separated from the injection port 209, the return spring 309 rebounds to push the piston 308 to reset, so that the piston 308 blocks the material injection head 302, avoiding the flow of excess resin to the distribution pipe 307. And the electric heating wire 304 and the heat preservation layer 303 are arranged inside the material injection head 302, so that the resin is heated by the electric heating wire 304 after entering the material injection head 302, thereby improving the fluidity of the resin.

[0026] During use, the front plate 104 is pushed by the main hydraulic rod 103, so that the air charging pipe 203 and the air outlet 205 are communicated with the exhaust pipe 216 and the air extraction pipe 215, thereby enabling the air pump 214 to extract the air inside the negative pressure chamber 201, making the inside of the negative pressure chamber 201 in a negative pressure state. After the resin is poured into the mold, the bubbles inside the resin are removed by the negative pressure, so that the resin inside the mold can better encapsulate the piezoelectric ceramic components. Moreover, the negative pressure inside the negative pressure chamber can promote the resin to flow into the feeding port 209, improving the resin pouring speed. During the process of the air pump 214 extracting the air inside 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. The parts not involved in this device are the same as or can be implemented using the prior art.
