Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a supporting plate assembly for supporting a dielectric block. Background Art

[0002] With the advent of the 5G communication era, more stringent technical requirements have been placed on mobile communication systems. While achieving efficient and large-capacity communications, the modules in the mobile communication system need to be highly integrated, miniaturized, lightweight, and low-cost. Dielectric filters are used to filter out clutter or interference signals outside the communication signal frequency and are one of the most important components in mobile communication systems. Among them, dielectric filters can produce microwave wavelength compression effects because their resonant cavities are filled with materials such as ceramics with high dielectric constants, which can greatly compress the effective size of the resonant cavity and miniaturize the overall size of the dielectric filter.

[0003] The dielectric filter is composed of multiple dielectric resonators, which are formed by metallizing the surface of the dielectric block. The metallization of the dielectric block will affect the key performance of the filter, such as the Q value and reliability. The gaps in the surface metal layer formed by the metallization will leak signal energy, increase signal attenuation, and affect the working performance of the dielectric resonator. Summary of the invention

[0004] The main technical problem solved by the present application is to provide a supporting plate assembly, which can ensure that the metal layer of the dielectric block has a higher degree of integrity after being dried.

[0005] In order to solve the above technical problems, a technical solution adopted in the present application is: to provide a supporting plate assembly for supporting a medium block, comprising: a supporting plate and a plurality of supporting protrusions; the supporting plate comprises a relative supporting surface and a bottom surface; the supporting plate is arranged on the supporting surface, and the supporting protrusion has a pointed end, and the pointed end is used to support the medium block.

[0006] The supporting plate includes an outer frame and an inner hollow area, and the supporting protrusion is arranged on the outer frame.

[0007] The supporting plate is also provided with an isolation strip connected to the frame, and the isolation strip is used to separate the hollow area into multiple areas, and a supporting protrusion is provided on the isolation strip.

[0008] Among them, a plurality of through holes are arranged on the supporting plate, and a plurality of supporting protrusions respectively pass through the through holes and are fixed to the supporting plate.

[0010] The supporting protrusion includes a nail cap, a nail rod and a nail tip. The nail rod and the nail tip pass through the through hole and protrude from the supporting plate. The nail cap is located between the supporting plate and the fixed bottom plate to fix the supporting protrusion.

[0011] Wherein, the nail rod is provided with an avoidance groove, which is located at the connection between the nail rod and the nail tip and is used to prevent the nail rod from contacting the dielectric block.

[0012] The fixed bottom plate and the supporting plate have the same shape and size.

[0013] Among them, a plurality of connecting parts are also arranged on the supporting surface of the supporting plate. The connecting parts are grooves or protrusions, which are used for clamping with corresponding protrusions or grooves.

[0014] The connecting piece includes a plurality of connecting components, each of which includes connecting columns and connecting column sockets that cooperate with each other, and the plurality of connecting components are arranged opposite to each other in pairs at the edges of both sides of the supporting surface.

[0015] The beneficial effects of the present application are as follows: Different from the prior art, the support plate assembly disclosed in the present application is used to support the dielectric block for drying.

[0035] In order to make the purpose, technical solution and effect of the present application clearer and more specific, the present application is further described in detail below with reference to the accompanying drawings and examples.

[0036] The preparation process of dielectric resonator mainly includes the steps of powder preparation, pressing, sintering, metallization, electrode preparation, SMA (Surface Mount Assembly) patch and debugging. Powder preparation refers to grinding and mixing a predetermined amount of powder to obtain powder that meets the predetermined conditions; pressing refers to placing the powder on a mold and extruding it for preliminary forming to obtain a dielectric block embryo; sintering refers to placing the dielectric block embryo in a sintering furnace and firing it at high temperature to obtain a dielectric block; metallization refers to forming a metal layer on the surface of the dielectric block, so that the dielectric block becomes a complete conductor, namely a dielectric resonator; electrode preparation refers to removing a part of the metal layer in a specified area (for example, forming a ring shape), so that the dielectric block covered with the metal layer can distinguish between positive and negative electrodes; SMA patch refers to pasting the SMA patch on the dielectric resonator; debugging refers to grinding the metal layer at the bottom and side wall of the blind hole on the dielectric resonator, so as to debug the filtering performance of the dielectric resonator.

[0037] Among them, the role of metallization on the surface of the dielectric resonator is to confine the electromagnetic field within the dielectric block to prevent signal overflow, that is, to suppress signal attenuation. The metallized material can be a variety of metal materials or metal mixed materials, such as silver, copper, aluminum, titanium, tin, gold and other materials, or any combination thereof. For ease of description, this application takes silver as an example. It should be noted that the metallization process or equipment disclosed in this application is not limited to the metallization material being silver.

[0038] Traditional metallization processes mostly use screen printing methods, but dielectric resonators have higher requirements on the thickness and adhesion of the metal film layer due to their own porous and multi-grooved structure. The metallization method of dielectric resonators can form a metal layer on the surface of the dielectric block by dipping, electroplating, magnetron sputtering or welding. Among them, the dipping method has the advantages of simple process steps and low cost.

[0039] See also Figure 1 , Figure 1 FIG. 1 is a schematic diagram of a process of an impregnation method according to an embodiment of the present application. Figure 1 As shown, the method includes: an impregnation step, a drying step, and a sintering step.

[0040] The dipping step refers to dipping the dielectric block in the dipping liquid and drying it. Specifically, the dielectric block can be placed in a carrier, immersed in the dipping liquid, and after dipping for a certain period of time, the carrier is lifted and rotated to dry.

[0041] The applicant has found in long-term research that the dielectric block itself is small in size and has more blind holes and small holes in the chamber. Due to the viscosity of the impregnation liquid, the dielectric block is directly immersed in the impregnation liquid, and it is difficult for the impregnation liquid to penetrate into the blind holes and small holes. For example, the impregnation liquid can be a silver paste, and the silver paste can include: silver powder, organic carrier, inorganic additives, etc.; the organic carrier can include resin and organic solvent, and generally has a high viscosity. The viscosity of the silver paste used for impregnation can be 40-50dPa·s. The fluidity of the liquid of this viscosity on the surface of the dielectric block will be relatively poor, so it is more difficult to flow into the blind holes or small holes of the dielectric block during the impregnation process. In one embodiment, the impregnation liquid can be dripped into the blind holes and holes of the dielectric block first, and then the dielectric block can be placed in the impregnation liquid for silver immersion. However, this method not only requires the addition of a large number of dripping hole equipment, but also requires more manpower. In addition, during the metallization process of the dielectric block, in order to meet the metal layer thickness required by the product, the metallization process is often required to be repeated, that is, the dripping process is also required to be repeated, which prolongs the production cycle.

[0042] The medium block needs to be placed in the carrier, and then the carrier is connected and fixed to the impregnation device, and then the impregnation and drying steps are performed. In one embodiment, the carrier and the impregnation device can be fixed by a threaded connection. However, this connection method requires the operator to tighten or loosen the screw to complete the connection and separation of the carrier and the impregnation device, which consumes a lot of time and affects the efficiency of the metallization process; and in the process of screwing the screw, at least two operators are generally required to cooperate, which consumes a lot of manpower.

[0043] The dielectric blocks can be directly placed in the carrier for impregnation. However, in this way, the dielectric blocks will be stacked together, and the dielectric blocks will fit each other, and the impregnation liquid in the part that fits each other is difficult to penetrate. Therefore, this method is prone to problems such as uneven coverage of the impregnation liquid, or no impregnation liquid coverage in the stacked area, which affects the quality of the dielectric blocks.

[0044] The drying step is to dry the impregnation liquid on the dielectric block and fix the metal layer on the surface of the dielectric block. During the drying process, the temperature of the silver drying furnace can be about 160°C-220°C.

[0045] The dielectric block needs to be placed on a supporting jig for drying. However, during the drying process, the contact between the dielectric block and the supporting jig causes the wet impregnation liquid to adhere to the jig, resulting in a gap in the metal layer after drying, exposing the dielectric block embryo.

[0046] In addition, before drying, the dielectric block needs to be transferred from the carrier to a holding fixture used for drying. For example, a clamping tool such as a clamp or tweezers can be used to transfer the dielectric block. However, during the transfer process, the clamp or tweezers may contact the wet impregnation liquid and may scratch the impregnation liquid layer on the dielectric block, thereby causing the product to be unqualified.

[0047] The silver burning step refers to placing the dried dielectric block into a sintering furnace to sinter and form a metal layer, which is used to remove organic matter in the metal layer, so that the metal layer adheres firmly, thereby finally forming a conductive metal layer. In the sintering process, since the organic matter needs to be burned, the temperature of the sintering furnace can be 800℃-900℃.

[0048] To solve the above problems, the relevant equipment structure in the metallization process can refer to the description of the following embodiments.

[0049] The impregnation device is used to immerse the dielectric block in the impregnation liquid so that the surface of the dielectric block is covered with the impregnation liquid, and then rotate to shake off the excess impregnation liquid on the surface of the dielectric block, so that a uniform wet impregnation liquid layer is formed on the surface of the dielectric block.

[0050] The impregnation device may include an impregnation chamber and a control device, etc. The impregnation chamber may be used to carry the impregnation liquid and the medium block to be impregnated for impregnation; the control device may be used to control the movement of the components in the impregnation chamber, and may also be used to control the environmental conditions in the impregnation chamber, etc.

[0051] See also Figure 2 , Figure 2 1 is a schematic diagram of the structure of an impregnation device according to an embodiment of the present application, wherein the impregnation device 1 comprises an impregnation barrel 11 and a vacuum system 12 ; the impregnation barrel 11 comprises a barrel body 111 and a cover plate 112 .

[0052] The impregnation barrel 11 is used to carry the impregnation liquid required for impregnation. For example, the impregnation liquid can be a silver slurry. The impregnation liquid has a certain viscosity, and its fluidity is limited by itself.

[0053] Specifically, the barrel body and the cover plate 112 of the dipping barrel 11 can move relative to each other to realize the opening and closing of the dipping barrel 11. Specifically, the cover plate 112 can move relative to the dipping barrel 11 in the axial direction of the dipping barrel 11, or move relative to each other in a direction perpendicular to the axial direction. When the barrel body 111 and the cover plate 112 are separated, the medium block to be impregnated can be placed in the dipping barrel 11 or taken out of the dipping barrel 11. When the barrel body 111 and the cover plate 112 are closed, a closed space can be formed in the dipping barrel 11. The barrel body 111 and the cover plate 112 can be made of alloy steel, aluminum alloy, stainless steel or glass. The barrel body 111 and the cover plate 112 can be made of the same material or different materials.

[0054] In one embodiment, the vacuum system 12 is connected to the impregnation barrel 11 to provide a negative pressure environment for the enclosed space in the impregnation barrel 11. The vacuum system 12 may include any applicable air moving components, such as a fan, a vacuum pump, a pipeline, a throttle valve, etc. The vacuum system 12 may be connected to the barrel body 111 or to the cover plate 112.

[0055] Specifically, during the use of the above-mentioned impregnation equipment, the objects to be impregnated are placed in the impregnation barrel 11, and then the cover plate 112 is closed, and the vacuum system 12 is started to evacuate the impregnation barrel 11, and the objects to be impregnated are impregnated under a negative pressure environment.

[0056] The impregnation device disclosed in the present application can provide a negative pressure environment when the dielectric block is impregnated. The suction force generated by the negative pressure can firmly adsorb the impregnation liquid on the surface of the dielectric block and immerse it into the blind holes or small holes of the dielectric block, so that the entire surface area of ​​the dielectric block is covered with silver paste. No other hole-dropping auxiliary equipment is required, which saves the hole-dropping time before impregnation and reduces the manpower and equipment costs.

[0057] See also Figures 3A-3C , Figure 3A It is a schematic structural diagram of an impregnation barrel according to one embodiment of the present application. Figure 3B It is a schematic diagram of an axial cross-section of a driving rod according to an embodiment of the present application. Figure 3C yes Figure 3A The immersion barrel 11 includes a barrel body 111 and a cover plate 112 .

[0058] In one embodiment, the cover plate 112 is provided with a pressure detection device 1121. The pressure detection device 1121 can be used to detect the pressure in the soaking barrel 11 in real time. The pressure detection device 1121 can be any suitable detection device such as a pressure gauge.

[0059] In one embodiment, the cover plate 112 may also be provided with an exhaust valve 1122 for ventilating the inside of the dipping barrel 11 to relieve the negative pressure environment. Specifically, the safety valve may be a solenoid valve. Under negative pressure, the cover plate 112 and the dipping barrel 11 cannot be separated, and air needs to be introduced into the dipping barrel 11 to make the pressure inside the barrel the same as that outside the barrel before the dipping barrel 11 can be opened.

[0060] In one embodiment, the cover plate 112 is provided with an air duct 1123 that penetrates the cover plate 112 and is used to connect with a vacuum system. When the dipping barrel 11 is closed, the vacuum system can extract the gas in the dipping barrel 11 through the air duct 1123. It should be noted that the air duct 1123 can also be provided on the dipping barrel 11 for connecting with a vacuum system.

[0061] In one embodiment, the impregnation device further includes a driving device 13, which is connected to the impregnation barrel 11 and is used to drive the barrel body 111 and the cover plate 112 to move relative to each other, so as to realize the opening and closing of the impregnation barrel 11. It should be noted that the driving device 13 can have multiple implementations, and the barrel body 111 can be connected to the driving device 13, or the cover plate 112 can be connected to the driving device, or both the barrel body 111 and the cover plate 112 are connected to the driving device 13, and the driving device 13 is used to drive the barrel body 111 and the cover plate 112 to move relative to each other. For example, the driving device 13 can drive the cover plate 112 to move, or it can drive the impregnation barrel 11 to move. Alternatively, the cover plate 112 and the barrel body 111 can be driven to move in different directions at the same time, for example, the cover plate 112 moves along the axial direction of the impregnation barrel 11, and the barrel body 111 moves along the vertical direction of the axial direction of the impregnation barrel 11, so as to facilitate the loading and unloading of the impregnated material.

[0062] In one embodiment, the driving device 13 may include a driving rod 131 fixed on the top of the dipping barrel 11 and fixedly connected to the cover plate 112. The cover plate 112 can move under the drive of the driving rod 131, so as to realize the closing and opening of the dipping barrel 11. The driving rod 131 can also pass through the cover plate 112 and extend to the barrel body 111 to be connected to the carrying device of the material to be dipping. The driving rod 131 can drive the carrying device to move up and down, or rotate.

[0063] In one embodiment, a fixing portion 1311 is further provided at the bottom end of the driving rod 131 for connecting with a carrying device of the material to be impregnated. The fixing portion 1311 may be circular, oval or square. For example, the fixing portion 1311 may be a flange.

[0064] In one embodiment, the driving rod 131 includes a rotating rod 1312 and a sleeve rod 1313, wherein the sleeve rod 1313 is sleeved on the outer periphery of the rotating rod 1312, and the sleeve rod 1313 is sealed and fixedly connected to the cover plate 112. The sleeve rod 1313 and the cover plate 112 can be sealed and fixedly connected by using rubber material, silicone material, etc. Thus, it is prevented that gas enters the dipping barrel 11 from the gap between the sleeve rod and the cover plate, which is conducive to forming a closed space when the dipping barrel 11 is closed.

[0065] In one embodiment, the driving device 13 further includes a driving motor 132, a connecting device 133, a sliding plate 134 and a fixing plate 135. The driving motor 132 is disposed above the dipping barrel 11 and connected to the driving rod 131, and is used to drive the driving rod 131 to move or rotate axially. The driving motor 132 includes a first driving motor 1321 and a second driving motor 1322. The first driving motor 1321 can drive the rotating rod 1312 and the sleeve rod 1313 to move axially along the driving rod. Thus, the sleeve rod 1313 can drive the cover plate 112 to move axially along the driving rod 131 to realize the opening and closing of the dipping barrel 11.

[0066] Specifically, the rotating rod 1312, the sleeve rod 1313 and the second drive motor 1322 are fixedly connected to the connecting device 133. The connecting device 133 is fixed to one side of the sliding plate 134 and can slide along the sliding plate 134. In addition, the other side of the sliding plate 134 is fixedly connected to the nut 137. Among them, the sliding plate 134 is located on the front side of the fixed plate 135, and the back side of the fixed plate 135 is provided with a screw rod 136 and a first drive motor 1321. The first drive motor 1321 can drive the screw rod 136 to rotate. The nut 137 is sleeved on the outer periphery of the screw rod 136, and when the screw rod 136 rotates, the nut 137 can move along the axial direction of the screw rod 136.

[0067] When in use, the first drive motor 1321 drives the screw rod 136 to rotate, and the nut 137 moves along the axial direction of the screw rod 136 as the screw rod 136 rotates, thereby driving the sliding plate 134 set on the front side of the fixed plate 135 and the rotating rod 1312 and the sleeve rod 1313 fixedly connected to the sliding plate 134 to move.

[0068] The second driving motor 1322 is connected to the rotating rod 1312, and the second driving motor 1322 can drive the rotating rod 1312 to rotate. When the rotating rod 1312 rotates, the rotating rod 1312 will not drive the sleeve rod 1313 to rotate. A fixing portion 1311 is provided at one end of the rotating rod 1312 close to the barrel body. Therefore, under the drive of the second driving motor, the rotating rod 1312 can drive the fixing portion 1311 to rotate.

[0069] In one embodiment, at least one end of the sleeve rod 1313 is provided with a sealing structure 1314, and the sealing structure 1314 fills the gap between the sleeve rod 1313 and the rotating rod 1312. The sealing structure is used to achieve the seal between the sleeve rod and the rotating rod. For example, the sleeve rod 1313 can be provided with a sealing structure 1314 at both ends, so that the gas cannot enter the impregnation barrel from the gap between the sleeve rod and the rotating rod, which is conducive to the formation of a closed space when the impregnation barrel is closed. The sealing structure can be made of rubber material, silicone material, etc. During the impregnation process, it is necessary to place the medium block to be impregnated in the impregnation carrier device, and then fix the impregnation carrier device to the impregnation equipment, and then the medium block to be impregnated can be impregnated. The present application discloses a carrier device used in an impregnation equipment, which can realize the fixed connection between the carrier device and the impregnation equipment by clamping, which is simple to operate and can effectively improve the metallization efficiency.

Figure 6 It is a schematic diagram of a partially enlarged structure of a connection portion according to an embodiment of the present application. Figure 7 It is a schematic diagram of the structure of a clamping block according to an embodiment of the present application. Figure 8 It is a schematic structural diagram of a supporting device used in an impregnation device according to another embodiment of the present application.

[0071] The impregnation bearing device 2 comprises a bearing frame 21, a connecting portion 22 and a clamping block 23. It should be noted that the bearing device includes but is not limited to a medium block for bearing.

[0072] The connecting part is connected to the impregnation device. The connecting part can be a plate-like structure or a frame structure. The supporting frame 21 includes a frame body 212 and a connecting rod 211. The connecting rod 211 can be one or more. One end of the connecting rod 211 is connected to the frame body 212. The other end of the connecting rod 211 is provided with a clamping groove 2111 for connecting with the connecting part 22. The clamping block 23 is movably connected to the connecting part 22. The clamping block 23 can be at least partially embedded in the clamping groove 2111 to engage with the connecting rod 211, thereby realizing the connection between the connecting rod 211 and the connecting part 22.

[0073] The carrier device used in the impregnation equipment disclosed in the present application can complete the fixed connection between the carrier frame 21 and the connecting portion 22 by only pushing the clamping block 23 to move so that the clamping block 23 is embedded in the clamping groove 2111. The fixing process of the carrier frame 21 and the connecting portion 22 does not require operations such as screwing, which greatly saves operation time and improves metallization efficiency.

[0074] The connecting portion 22 includes a connecting plate 221, and a through hole 2211 is provided on the connecting plate 221 for accommodating a connecting rod 211 and connecting the connecting portion 22. The width of the through hole 2211 is greater than or equal to the maximum diameter of the connecting rod 211, so that the connecting rod 211 can pass through the through hole 2211. In one embodiment, the connecting portion 22 can be provided with a connecting structure for connecting with an impregnation device. For example, a screw hole or a card hole can be provided at the center of the connecting plate 221. The connecting plate 221 can be connected to a moving device in the impregnation device, so that the bearing frame 21 can be driven to move. The connecting plate 221 can be made of a material with a large bearing capacity, such as a metal material. Specifically, the connecting plate 221 can be made of alloy steel, aluminum alloy or stainless steel. The connecting plate 221 can be square, round or oval. For example, the connecting plate 221 can be a flange. A flange refers to a metal body similar to a disk with a plurality of holes for fixing opened around it for connecting other components.

[0075] The clamping block 23 includes a frame 231 and a clamping groove 232 formed by the frame 231. The clamping groove 232 includes a first clamping groove 2321 and a second clamping groove 2322 that are connected. The groove width of the first clamping groove 2321 is greater than the groove width of the second clamping groove 2322, so that the first clamping groove 2321 can allow the connecting rod 211 to pass through but does not clamp the connecting rod 211. The shape of the second clamping groove 2322 matches the shape of the clamping groove 2111, so that the second clamping groove 2322 clamps the connecting rod 211. That is, after the connecting rod 211 passes through the first clamping groove 2321, the clamping block 23 moves to embed the second clamping groove 2322 into the clamping groove 2111 to complete the clamping.

[0076] In one embodiment, the shape of the second clamping groove 2322 may be similar to that of the clamping groove 2111. This allows the clamping block 23 to be more tightly fitted and clamped with the connecting rod 211. Specifically, if the clamping groove 2111 is square, the clamping block 23 may have a square second clamping groove 2322 structure. If the clamping groove 2111 is cylindrical, the clamping block 23 may have an arc-shaped second clamping groove 2322 structure with a similar or identical radius, for example. Figure 7 as shown in .

[0077] A limiting hole 2311 is provided on the frame 231 of the clamping block 23, and a limiting rod 222 is provided on the connecting portion 22. The limiting rod 222 is inserted into the limiting hole 2311 to limit the range of motion of the clamping block 23. Thus, the clamping block 23 can move linearly within a specified range, avoiding the situation where the clamping block 23 is offset due to uneven force.

[0078] The supporting device includes a pushing member 24, which is connected to the clamping block 23 and is used to push the clamping block 23 to move so that the connecting rod 211 moves relative to the clamping block 23, moving from the first clamping groove 2321 to the second clamping groove 2322 to achieve clamping with the clamping block 23.

[0079] In one embodiment, the pusher 24 includes an elastic member (not shown). The elastic member can be any applicable elastic member. One end of the elastic member is fixed to the connecting portion 22, and the other end is fixed to the clamping block 23, so that the clamping block 23 can be pushed to move. The number of elastic members can be one or more. For example, there can be two elastic members, which are arranged in parallel at both ends of the clamping block 23 that are perpendicular to the elastic member. The clamping block 23 can be pushed to move on the connecting portion 22 by an external force, and the elastic block is deformed during the movement of the clamping block 23. After the external force is removed, the clamping block 23 can be pulled back to its initial position by the elastic block.

[0080] In one embodiment, the elastic member is specifically a spring, which has the advantages of good energy storage effect, convenient installation, low cost, etc., and can be replaced in time when damaged.

[0081] In one embodiment, the frame body 212 of the carrier frame 21 includes a first frame (top frame) 2121, a second frame (bottom frame) 2122 and a column 2123, wherein the column 2123 is located between the two top frames 2121 and the bottom frame 2122, connecting the top frame 2121 and the bottom frame 2122. Among them, the top frame 2121 is close to the connecting portion 22, and the bottom frame 2122 is far away from the connecting portion 22. The top frame 2121 and the bottom frame 2122 are parallel to each other, and the column 2123 and the top frame 2121 / bottom frame 2122 are perpendicular to each other. The column 2123 is arranged at the edge and / or center of the top frame 2121 and the bottom frame 2122. The top frame 2121 and the bottom frame 2122 have the same shape and size. The top frame 2121 and the bottom frame 2122 can be circular, oval or square, etc. The top frame 2121 only includes the edge frame, and the bottom frame 2122 includes the edge frame and the bearing rod 21221 arranged between the edge frames, which is used to carry the items to be impregnated. Among them, the bearing frame 21 can be used to carry a fixing device that fixes the items to be impregnated. Of course, the screen can also be directly covered on the bearing frame 21, and the items to be impregnated can be directly placed in the bearing frame 21 for impregnation.

[0082] In one embodiment, the connecting rod 211 can be disposed on the top frame 2121 of the carrying frame 21 and is higher than the top frame 2121 of the carrying frame 21. The connecting rod 211 can be fixed to the carrying frame 21 by screwing, clamping or welding. Figure 6 As shown, the top frame 2121 of the carrying frame 21 has a screw hole, and the connecting rod 211 passes through the screw hole and is fixedly connected to the carrying frame 21 through a nut.

[0083] When the above-mentioned carrying device is used, the sample to be impregnated is placed in the carrying frame 21, and the clamping block 23 is pushed to open the through hole 2211. At this time, the elastic member is compressed, and the connecting rod 211 on the carrying frame 21 is passed through the through hole 2211. Then the clamping block 23 is released, and the elastic member rebounds, pushing the clamping block 23 to move above the through hole 2211, and clamping with the clamping groove 2111 of the connecting rod 211 to fix the connection between the carrying frame 21 and the connecting part 22. In the clamped state, the thicker end of the connecting rod 211 is placed on the connecting part 22, and the thinner area of ​​the connecting rod 211 is clamped between the side wall of the clamping groove 232 and the side wall of the clamping block 23, so that the carrying frame 21 and the connecting part 22 are fixedly connected.

[0084] See also Figure 8In one embodiment, the bearing device is further provided with a protective cover 25, which is connected to the fixing portion and is used to accommodate at least part of the clamping block 23 and the pushing member 24. Specifically, the protective cover 25 is arranged above and on the side of the clamping block 23 and the elastic member. Specifically, the protective cover 25 may include an upper shell wall 251 and a side shell wall 252, wherein the upper shell wall 251 may cover the elastic member and a partial area of ​​the clamping block 23, and the side shell wall 252 may include at least three side cover plates, which are respectively located at one end of the elastic member away from the clamping block 23 and can be connected to the elastic member; and on both sides parallel to the elastic member. The protective cover 25 can protect the clamping block 23 and the elastic member from being contaminated, and further limit the clamping block 23 so that the clamping block 23 will not be separated from the connecting portion 22.

[0085] In one embodiment, the connection part 22 can be connected to the connection rod 211 in the impregnation device. Specifically, the connection part 22 is connected to the fixing disk at the end of the connection rod 211, and the connection method can include screw connection, clamping or welding. Under the drive of the connection rod 211, the load-bearing device can be driven to move up and down or rotate. Of course, the connection part 22 in the load-bearing device and the fixing disk at the end of the connection rod 211 can be the same component, that is, the connection part 22 of the load-bearing device is directly connected and fixed to the connection rod 211.

[0086] The present application discloses an impregnation fixture, which can isolate impregnated objects from each other, thereby solving the problem of uneven impregnation caused by the objects to be impregnated stacking on each other during the impregnation process. The objects to be impregnated can refer to the objects themselves or to a fixture for clamping the objects, such as a medium block or a fixture for clamping the medium block. For ease of description only, the present application takes the medium block as an example for explanation. It should be noted that the impregnation fixture disclosed in the present application is not limited to a fixture for fixing a medium block or a fixture for clamping a medium block.

[0087] See also Fig. 9 , Fig.10 , Fig. 9 It is a schematic structural diagram of an impregnation and fixing device according to one embodiment of the present application. Fig.10 It is a schematic structural diagram of a support plate according to one embodiment of the present application.

[0088] The impregnation and fixing device 3 includes a receiving frame 31 and at least one supporting plate 32. The receiving frame 31 includes a supporting bottom plate 311 and a supporting rod 312. At least one supporting plate 32 is fixed on the supporting rod 312, and is stacked and spaced apart with the supporting bottom plate 311. A plurality of receiving grooves 321 are provided on the supporting plate 32, and the receiving grooves 321 are used to receive items to be impregnated.

[0089] The supporting bottom plate 311 plays a supporting role and is mainly used to support the items to be impregnated, such as a dielectric block or a fixture for holding a dielectric block. In one embodiment, the supporting bottom plate 311 can be made of a metal material, such as alloy steel, aluminum alloy or stainless steel. The shape of the supporting bottom plate 311 can be polygonal, circular or elliptical. Specifically, the shape of the supporting bottom plate 311 can be circular.

[0090] In one embodiment, the supporting bottom plate 311 is a hollow plate, wherein the hollow area 3111 and the orthographic projection of the accommodating groove 321 on the supporting bottom plate 311 partially overlap or do not overlap. During the impregnation process, the medium block needs to be immersed in the impregnation liquid. The supporting bottom plate 311 is set as a hollow plate so that the impregnation liquid can directly contact the impregnated items through the supporting bottom plate 311, thereby improving the impregnation effect. It should be noted that the supporting bottom plate 311 can also be a mesh structure, as long as it can play a supporting role and the impregnation liquid can directly contact the items to be impregnated through the supporting bottom plate 311 during the impregnation process.

[0091] The support rod 312 plays a supporting and fixing role. The support rod 312 can be made of alloy steel, aluminum alloy or stainless steel. The support rod 312 and the supporting base plate 311 can be detachably connected or non-detachably connected. Specifically, the support rod 312 can be non-detachably connected to the supporting base plate 311 by welding or bonding, or can be detachably connected to the supporting base plate 311 by screwing or clamping. The support rod 312 can be perpendicular to the base plate, for example, when the base plate is placed on a horizontal plane, the support rod 312 extends in the vertical direction.

[0092] The support rods 312 can be arranged at intervals along the edge of the supporting bottom plate 311, or can be arranged at intervals near the center of the supporting bottom plate 311. Thus, the support rods 312 arranged between the center and the edge of the supporting bottom plate 311 are reduced, so that while ensuring the fixing effect of the support plate 32, the number of support rods 312 is reduced, and the processing cost of the accommodating frame 31 is effectively reduced.

[0093] The support rod 312 is provided with a limiting structure for limiting the position of the support plate 32 on the accommodating frame 31. Specifically, the support rod 312 may be tapered in a stepwise manner from the supporting bottom plate 311 in the extension direction, so that the support plate 32 may be limited from sliding in the direction of the supporting bottom plate 311. The limiting structure may also be any other structure capable of limiting the position of the support plate 32, such as a slot, a clip, a limiting protrusion, etc. The support rod 312 may be made of alloy steel, aluminum alloy, stainless steel, etc.

[0094] The receiving groove 321 is used to receive the object to be impregnated, such as a dielectric block or a fixture for holding the dielectric block. The receiving groove 321 is a through groove that penetrates the support plate 32, so that the object to be impregnated is clamped in the receiving groove 321 and touches the supporting bottom plate 311. Therefore, the shape and size of the receiving groove 321 can be determined according to the shape and size of the object to be accommodated. For example, the receiving groove 321 can be rectangular.

[0095] The shape of the support plate 32 can be square or circular. In one embodiment, the support plate 32 is circular, and the receiving grooves 321 are arranged in an array in the circumferential direction of the support plate 32 with the center of the circle of the support plate 32 as the center. This arrangement can ensure that the objects to be dipped do not affect each other, and the number of receiving grooves 321 can be as large as possible.

[0096] In one embodiment, see Fig. 9 The support plate 32 is circular, the extension line of the receiving groove 321 may pass through the center of the circle, and the position of the receiving groove 321 coincides with the radius of the support plate 32. This arrangement can maximize the distance between the receiving grooves 321 while ensuring the number of the receiving grooves 321, thereby reducing the mutual influence between the received medium blocks during the immersion and drying process.

[0097] In one embodiment, see Fig.10 , the support plate 32 may also be circular, and the extension line of the receiving groove 321 may not pass through the center of the circle, and may have a certain angle with the radius of the support plate 32. The angles between the extension lines of all the receiving grooves on the support plate 32 and the radius of the support plate 32 are the same. This arrangement can reduce the angle between the receiving groove and the tangent line of the support plate 32, thereby reducing the mutual interference between the received objects to be impregnated during the spin-drying process after impregnation, improving the spin-drying effect, and making the thickness of the impregnation liquid layer on the objects to be impregnated uniform, for example, making the thickness of the metal layer on the dielectric block uniform.

[0098] There are at least two support plates 32, which are stacked and spaced apart. Both support plates 32 are provided with a receiving groove 321 that penetrates the support plates 32. The receiving grooves 321 of the two support plates 32 are arranged opposite to each other, so that the object to be impregnated passes through the receiving groove 321 and is clamped between the two support plates 32. Therefore, multi-stage fixation of the object to be impregnated (the dielectric block or the clamp holding the dielectric block) can be achieved. The multi-stage fixation method can effectively improve the stability of the object to be impregnated placed on the impregnation fixture 3, and prevent the object to be impregnated from falling off the impregnation fixture 3 during the impregnation process, which affects the metallization effect.

[0099] In one embodiment, there are two support plates 32, which are respectively arranged near the top and the bottom of the support rod 312. Thus, the upper and lower parts of the objects to be dipped can be fixed. This ensures that the objects to be dipped will not fall off the dipping fixture 3 when the dipping fixture 3 rotates or moves up and down. At the same time, the number of support plates 32 is only two, which can reduce the manufacturing cost of the dipping fixture 3.

[0100] The support plate 32 may also be provided with a first limiting structure 322, such as a through hole, which cooperates with the limiting device of the support rod 312. The arrangement position of the first limiting structure 322 on the support plate 32 corresponds to the arrangement position of the support rod 312. The support plate 32 may be made of materials such as alloy steel, aluminum alloy or stainless steel. When the above-mentioned impregnation fixing device 3 is used, it is necessary to insert the object to be impregnated (the medium block or the clamp holding the medium block) into a plurality of correspondingly connected accommodating grooves 321, and the plurality of connected accommodating grooves 321 are respectively arranged on a plurality of support plates 32, so that the object to be impregnated contacts the supporting bottom plate. Thus, the bottom surface of the object to be impregnated is supported on the supporting bottom plate 311, and the side wall of the object to be impregnated passes through a plurality of correspondingly connected accommodating grooves 321 to realize multi-stage fixation of the object to be impregnated, which effectively improves the stability of the object to be impregnated during the impregnation or spin-drying process. In addition, since the objects to be impregnated are respectively fixed in the mutually spaced receiving grooves 321, the objects to be impregnated will not overlap each other, the objects to be impregnated can be fully in contact with the impregnation liquid, and a uniform and complete impregnation liquid layer can be formed on the surface of the objects to be impregnated, thereby improving the impregnation effect.

[0101] In one embodiment, the impregnation fixture 3 is further provided with a second limiting structure 33, which is used to limit the position of the impregnation fixture 3 when connected and fixed with the impregnation equipment, so as to drive the displacement of the impregnation fixture 3. Specifically, the second limiting structure 33 may include a slot 331 provided at the edge of the support plate 32 and the supporting bottom plate 311, and a positioning hole 332 provided at the center of the support plate 32 and the supporting bottom plate 311.

[0102] The impregnation fixture 3 can be placed in the aforementioned bearing frame, wherein the second limiting structure 33 can be used to limit the position of the impregnation fixture 3 in the bearing frame so that it will not slide in the bearing frame. In addition, the second limiting structure 33 can also drive the impregnation fixture 3 to rotate with the bearing frame. Specifically, the column 2123 arranged at the center of the bearing frame can pass through the positioning hole 332 in the center of the support plate 32 and the supporting bottom plate 311 to limit the position of the impregnation fixture 3 in the bearing frame. The column 2123 of the bearing frame can also be provided with a limiting protrusion for cooperating with the card slot 331 arranged at the edge of the support plate 32 and the supporting bottom plate 311, so that the impregnation fixture 3 will not rotate relative to the bearing frame.

[0103] The present application discloses a dielectric block clamp, which can isolate dielectric blocks from each other, thereby solving the problem of uneven impregnation caused by dielectric blocks stacking on each other during the impregnation process. In addition, the dielectric block is fixed in the dielectric block clamp, and when the dielectric block is taken out of the impregnation device, the clamping tool does not need to directly contact the dielectric block, thereby avoiding the situation where the clamping tool damages the impregnation liquid layer on the surface of the dielectric block.

[0104] See also Figure 11-13 , Fig.11 It is a schematic structural diagram of a dielectric block clamp according to an embodiment of the present application. Fig.12 It is a schematic structural diagram of a splint according to one embodiment of the present application. Fig.13 It is a partial enlarged structural schematic diagram of a carrier according to an embodiment of the present application. It should be noted that the dielectric block disclosed in the present application is not limited to being used for clamping dielectric blocks for impregnation.

[0105] The dielectric block fixture 4 includes at least two clamping plates 41, which are movably connected to each other, and the dielectric block 6 can be fixed between the two clamping plates 41. Of course, the dielectric block fixture 4 can also include three or more clamping plates 41, and the dielectric block 6 can be fixed between two adjacent clamping plates 41. The clamping plates 41 can be made of metal materials or polymer materials with a certain strength.

[0106] Each clamping plate 41 includes: a placement position 411 and at least two bearing platforms 412. The placement position 411 is formed by a plurality of frame strips 413 connected in sequence, and is used to accommodate the dielectric block 6. That is, the placement position 411 is a frame structure, and is hollow inside. At least two bearing platforms 412 are arranged on the frame strips 413 and are located at the bottom of the placement position 411. The two bearing platforms 412 can be arranged on the frame strips 413 opposite to each other, and the bearing platforms 412 are used to prevent the dielectric block 6 from leaking out of the placement position 411. The placement positions 411 of at least two clamping plates 41 are arranged relative to each other, so that the bearing platforms 412 on the clamping plates 41 can clamp the dielectric block 6. When the two clamping plates 41 are closed, the two placement positions 411 can form a accommodating cavity, and the dielectric block 6 is located in the accommodating cavity. The bearing platforms 412 in the two placement positions 411 clamp the two sides of the dielectric block 6 to fix the dielectric block 6.

[0107] When the dielectric block fixture 4 is used, the clamping plates 41 of the dielectric block fixture 4 are separated, one clamping plate 41 is placed horizontally with the support platform 412 located at the bottom, and the dielectric blocks 6 are placed on the support platforms 412 in the hollowed-out parts of the clamping plate 41; the other clamping plate 41 is placed on the dielectric block 6 with the support platform 412 of the other clamping plate 41 located at the top. The two clamping plates 41 are fixedly connected, and the dielectric block 6 is clamped and carried between the two clamping plates 41.

[0108] In the embodiment disclosed in the present application, the dielectric block 6 can be fixed in the fixture 4, and there is no contact between the dielectric blocks 6, so that it can effectively avoid that part of the dielectric block 6 cannot be covered by the impregnation liquid due to the contact between the dielectric blocks 6, reduce the situation of uneven impregnation, and improve the impregnation effect. In addition, the dielectric block 6 is fixed in the placement position 411 by using the carrier 412. The placement position 411 is a frame structure, which can reduce the contact area between the fixture 4 and the dielectric block 6, so that the impregnation liquid can better contact with the dielectric block 6.

[0109] The frame strip 413 includes a plate frame 4131 surrounding the clamping plate 41 and a partition rod 4132 connected to the plate frame 4131 . The partition rod 4132 is used to partition the clamping plate 41 into a plurality of placement positions 411 .

[0110] The plate frame 4131 includes a first plate frame, a second plate frame, a third plate frame and a fourth plate frame, and the four plate frames are connected end to end. The partition rod 4132 spans between the first plate frame and the third plate frame or between the second plate frame and the fourth plate frame. A plurality of partition rods 4132 are arranged in parallel with each other and are perpendicular to the spanned plate frames 4131. A placement position 411 is sandwiched between every two adjacent partition rods 4132. A plurality of placement positions 411 are arranged in parallel with each other. When the two clamping plates 41 are closed, the medium block 6 can be fixed in the placement position 411.

[0111] In one embodiment, a plurality of liquid leakage grooves 414 are provided on one side of the frame strip 413 away from the carrier 412, so as to allow the immersion liquid to flow into the fixture 4 and contact the dielectric block 6. When the two clamping plates 41 are closed, the liquid leakage grooves 414 on the two clamping plates 41 can form through holes, and the immersion liquid can enter the fixture 4 from the through holes, so that each side of the dielectric block 6 is easy to contact with the immersion liquid. Specifically, a first liquid leakage groove 4141 is provided on the plate frame 4131 perpendicular to the partition rod 4132, and the first liquid leakage groove 4141 can be provided between the two partition rods 4132. Each partition rod 4132 is provided with at least one second liquid leakage groove 4142, so that the liquid leakage groove 414 is provided on the frame strip 413 around each placement position 411. The width of the first liquid leakage groove 4141 and the second liquid leakage groove 4142 can be smaller than the width of the dielectric block 6, so as to prevent the dielectric block 6 from falling from the liquid leakage groove 414. In addition, the connection of the frame strips 413 around each placement position 411 is also provided with a third liquid leakage groove 4143, which facilitates the immersion liquid to flow into the fixture 4 and contact the dielectric block 6. Therefore, the corners of the dielectric block 6 can also fully contact with the immersion liquid to avoid dead corners.

[0112] In one embodiment, each frame strip 413 is provided with an isolation protrusion 415 on one side facing the inner side of the placement position 411. The isolation protrusion 415 is in direct contact with the dielectric block 6, and is used to reduce the contact area between the frame strip 413 and the dielectric block 6. The isolation protrusion 415 can effectively avoid the problem that the dielectric block 6 is difficult to cover the partial area of ​​the dielectric block 6 with the immersion liquid due to the close contact between the side of the dielectric block 6 and the frame strip 413. Specifically, a plurality of first isolation protrusions 4151 are provided on the opposite sides between the plate frames 4131, and a plurality of second isolation protrusions 4152 are provided on the opposite sides between the partition rods 4132, that is, at least four isolation protrusions 415 are provided on the inner side of each placement position 411. In order to further optimize the isolation effect, each frame strip 413 side around each placement position 411 includes at least two isolation protrusions 415, so that the dielectric block 6 can remain stable.

[0113] In one embodiment, a plurality of fixing members 416 are provided on one side of the plate frame 4131 away from the support platform 412. The fixing members 416 are grooves or protrusions for engaging with corresponding protrusions or grooves. The fixing members 416 include multiple groups of fixing components, each group of fixing components includes mutually cooperating fixing columns 4161 and fixing column sockets 4162, and the multiple groups of fixing components are arranged opposite to each other on two opposite sides of the frame strip 413. The fixing member 416 is used to fix the two clamping plates 41 when the two clamping plates 41 are closed. The shape of the fixing column socket 4162 can be determined according to the fixing column 4161, for example, the fixing column 4161 can be a screw, and the fixing column socket 4162 can have a threaded structure. For another example, the fixing column 4161 can be a pin, and the fixing column socket 4162 has a structure for use with the pin.

[0114] In one embodiment, there are multiple carriers 412, which are respectively arranged on the frame strips 413 around the placement position 411 and at the corners where two frame strips 413 are connected. The carrier 412 is connected to the plate frame 4131 and / or the partition rod 4132. The side of the carrier 412 in contact with the dielectric block 6 is also provided with a third isolation protrusion 4153, which is used to reduce the contact area between the dielectric block 6 and the carrier 412, so that the dielectric block 6 can fully contact with the immersion liquid. The carrier 412 can also be provided with a leakage hole 4121, so that the immersion liquid flows into the fixture 4 from the leakage hole 4121 and contacts with the dielectric block 6. Specifically, the leakage hole 4121 can be provided at the connection between the plate frame 4131 and the partition rod 4132, and is connected to the leakage groove 414.

[0115] The dielectric block fixture 4 disclosed in the present application is provided with a plurality of liquid leakage grooves 414 or liquid leakage holes 4121, which can facilitate the impregnation liquid to enter the dielectric block fixture 4 and fully contact the entire surface of the dielectric block 6. At the same time, it is provided with a plurality of isolation protrusions 415, which are used to reduce the contact area between the dielectric block 6 and the fixture 4, thereby avoiding the situation of uneven impregnation caused by the contact between the dielectric block 6 and the fixture 4.

[0116] The dielectric block fixture can be used in conjunction with the aforementioned carrying device of the impregnation device. Specifically, the dielectric block is clamped in the dielectric block fixture, and the dielectric block fixture with the dielectric block is directly placed into the carrying frame of the carrying device, and the carrying frame is fixedly connected to the connecting part before the subsequent impregnation process is performed.

[0117] The above-mentioned dielectric block clamp can also be used in conjunction with the aforementioned fixing device. Specifically, the dielectric block is clamped in the dielectric block clamp, the dielectric block clamp with the dielectric block is inserted into the receiving groove of the fixing device, and then the fixing device is placed in the impregnation device for the subsequent impregnation process.

[0118] The dielectric block fixture can also be used in conjunction with the aforementioned fixing device and the carrying device. Specifically, the dielectric block is clamped and carried in the dielectric block fixture, and the dielectric block fixture with the dielectric block is inserted into the receiving groove of the fixing device, and then the fixing device is placed in the carrying frame of the carrying device, and after the carrying frame is fixedly connected to the connecting part, the subsequent impregnation process is performed.

[0119] The above-mentioned dielectric block clamp can also be used in conjunction with the aforementioned fixing device, carrying device, and impregnation equipment. Specifically, the dielectric block is clamped in the dielectric block clamp, and the dielectric block clamp with the dielectric block is inserted into the receiving groove of the fixing device, and then the fixing device is placed in the carrying frame of the carrying device, and after the carrying frame is fixedly connected to the connecting part, the impregnation barrel of the impregnation equipment is closed, vacuumized, and the subsequent impregnation process is carried out.

[0120] The present application discloses a supporting plate assembly, which can be used to support a dielectric block during a drying process after impregnation, thereby reducing damage to a metal layer caused by contact with the supporting plate assembly during the drying process and improving the metallization quality of the dielectric block.

[0121] See also Figure 14-17 , Fig.14 It is a schematic diagram of the structure of a support plate assembly according to one embodiment of the present application. Fig.15 It is a schematic diagram of the structure of a support plate assembly according to another embodiment of the present application. Fig.16 yes Fig.15 Exploded diagram. Fig.17 It is a schematic structural diagram of a support protrusion according to an embodiment of the present application.

[0122] The supporting plate assembly 5 is used to support the medium block 6 during the drying process. The supporting plate assembly 5 includes a supporting plate 51, which includes a supporting surface and a bottom surface opposite to each other; and a plurality of supporting protrusions 52, which are arranged on the supporting surface.

[0123] In one embodiment, the support protrusion has a pointed end 5231, and the pointed end 5231 is used to support the dielectric block 6. The support protrusion 52 can be detachably fixed or non-detachably fixed. Since the end of the support protrusion 52 is pointed, the contact area between the support protrusion 52 and the dielectric block 6 is very small. The interval between the support protrusions 52 can be determined according to the length or width of the dielectric block 6. The dielectric block 6 can be supported by at most four support protrusions 52. For example, the support protrusions 52 can support the four corners of the dielectric block 6 respectively.

[0124] In the embodiment disclosed in the present application, the dielectric block 6 is supported by the supporting protrusion 52, and the contact area between the dielectric block 6 and the supporting plate is extremely small. During the drying process, the exposed porcelain area caused by the contact between the dielectric block 6 and the supporting plate is very small, and there will be no large-area exposed porcelain phenomenon. The metal layer of the dielectric block 6 has good integrity, which effectively improves the quality of the resonator.

[0125] In one embodiment, the supporting plate 51 includes an outer frame 511 and an inner hollow area 512, and the supporting protrusion 52 is arranged on the frame 511. By setting the hollow structure, not only can the heat energy absorbed by the supporting plate 51 in the drying device be reduced, but also the heat conduction of the medium block 6 during the drying process can be smoother, so that the drying is more complete.

[0126] The support plate 51 is also provided with an isolation strip 513 connected to the frame 511. The isolation strip 513 is used to separate the hollow area 512 into a plurality of areas. The isolation strip 513 is provided with a support protrusion 52. In one embodiment, the isolation strip 513 is provided in the frame 511 and connected to at least two sides of the frame 511. In one embodiment, the isolation strip 513 can be parallel to any side of the frame 511 and connected to two opposite sides of the frame 511. Specifically, the support plate 51 can be rectangular, and the isolation strip 513 is parallel to the long side or short side of the frame 511.

[0127] For example, Fig.14 As shown, there are two isolation bars 513 , and the isolation bars 513 are parallel to the long sides of the frame 511 . The dielectric blocks can be arranged in a row on the supporting plate 51 , and the arrangement direction of the dielectric blocks is parallel to the long sides of the frame 511 .

[0128] For example, Fig.15 As shown, there are four isolation bars 513, and the isolation bars 513 are parallel to the short sides of the frame 511 of the supporting plate 51. The dielectric blocks can be arranged in two columns on the supporting plate 51, and the arrangement direction between the columns is parallel to the long sides of the frame 511. The arrangement direction of the dielectric blocks in each column is parallel to the short sides of the frame 511.

[0129] For another example, the number of the isolation bars 513 is two, and the isolation bars 513 are parallel to the short side of the frame 511 of the supporting plate 51. The dielectric blocks can be arranged in two columns on the supporting plate 51, and the arrangement direction between the columns is parallel to the long side of the frame 511. The arrangement direction of the dielectric blocks in each column is parallel to the short side of the frame 511.

[0130] Of course, the number of the isolation strips 513 can be any other value, and the isolation strips 513 can also be arranged obliquely in the frame 511, not parallel to any side of the frame 511. The isolation strips 513 can be connected to any single side of the frame 511, or to both sides, such as two sides of the frame 511 that are parallel to each other, or two sides of the frame 511 that are perpendicular to each other. The arrangement of the dielectric blocks 6 can be determined according to the arrangement direction of the isolation strips 513.

[0131] The supporting plate assembly 5 further includes a fixed bottom plate 53 , which is disposed on the bottom surface of the supporting plate 51 and is used to fix the supporting protrusion 52 on the supporting plate 51 .

[0132] In one embodiment, the fixed base plate 53 is detachably connected to the supporting plate 51. The connection method between the fixed base plate 53 and the supporting plate 51 can be a snap connection, a pin connection or a screw connection, which is not limited here. The fixed base plate 53 and the supporting plate 51 can be provided with corresponding structures for connection and fixation. For example, the fixed base plate 53 and the supporting plate 51 can be connected by screws, and the fixed base plate 53 and the supporting plate 51 are provided with a plurality of threaded holes 515 for the screws to pass through to fix the fixed base plate 53 and the supporting plate 51. The fixed base plate 53 and the supporting plate 51 have the same shape and size. Of course, the fixed base plate 53 can also be a plurality of strip plates, which are respectively fixed to the areas of the supporting plate 51 where the support protrusions 52 are provided.

[0133] In one embodiment, a plurality of through holes 514 are disposed on the supporting plate 51 , and a plurality of supporting protrusions 52 pass through the through holes 514 and are fixed to the supporting plate 51 .

[0134] In one embodiment, the support protrusion 52 includes a nail cap 521, a nail rod 522 and a nail tip 523. The nail tip 523 is conical, with a gradually decreasing diameter, a pointed end with a smaller diameter, and a larger diameter end connected to the nail rod 522.

[0135] The nail rod 522 and the nail tip 523 pass through the through hole 514 and protrude from the supporting plate 51, and the nail cap 521 is located between the supporting plate 51 and the fixed bottom plate 53 to fix the supporting protrusion 52. The supporting plate 51 is fixedly connected to the fixed bottom plate 53, and the top cap of the supporting protrusion 52 is clamped between the supporting plate 51 and the fixed bottom plate 53, so that the supporting protrusion 52 is fixed. When the supporting plate 51 is separated from the fixed bottom plate 53, the supporting protrusion 52 can be taken out. When the supporting protrusion 52 is damaged, the damaged supporting protrusion 52 can be taken out and replaced, which can effectively extend the service life of the supporting plate 51 and save costs.

[0136] In one embodiment, see Fig.17 The nail rod 522 is provided with an avoidance groove 5221, which is located at the connection between the nail rod 522 and the nail tip 523, and is used to prevent the nail rod 522 from contacting the dielectric block. Specifically, a groove is provided in the area of ​​the nail rod 522 near the nail tip 523, and the diameter of the nail rod 522 in the groove part is smaller than the maximum diameter of the nail tip 523, and the nail tip 523 is covered on the nail rod 522 in a mushroom shape.

[0137] The surface of the dielectric block 6 is provided with a plurality of blind holes, and after metallization, the dielectric block 6 can be debugged by grinding the metal layer at the bottom of the blind holes. Therefore, during drying, the contact point between the support protrusion 52 and the dielectric block 6 is positioned in the blind hole, which can avoid damaging the metal layer on other surfaces and further improve the integrity of the metal layer on the surface of the dielectric block 6.

[0138] In one embodiment, the height of the nail tip 523 is less than the depth of the blind hole of the dielectric block 6, so that when the dielectric block 6 is carried, the entire area of ​​the nail tip 523 is located in the blind hole of the dielectric block 6. When the dielectric block 6 is slightly shaken on the supporting plate 51, only the edge of the larger diameter end of the nail tip 523 contacts the side wall of the blind hole, and the contact area is small. Even if the impregnation liquid adheres, the exposed magnetic area is very small after the dielectric block 6 is detached, thereby ensuring the quality of the metallization of the dielectric block 6.

[0139] In one embodiment, the supporting surface of the supporting plate 51 is further provided with a plurality of connecting members 54, and the connecting members 54 are grooves or protrusions, which are used to engage with corresponding protrusions or grooves. The connecting members 54 include multiple groups of connecting components, each group of connecting components includes connecting columns 541 and connecting column sockets 542 that cooperate with each other, and the multiple groups of connecting components are arranged opposite to each other on the two side edges of the supporting surface. The connecting columns 541 and the connecting column sockets 542 in each group of connecting components are respectively arranged on the two side edges of the supporting surface, and are arranged opposite to each other. Therefore, when the medium block 6 is transferred between the two supporting plates 51, the two supporting plates 51 are interlocked, and the connecting columns 541 can be inserted into the connecting column sockets 542, so as to play a positioning role. The connecting column sockets 542 can also be a boss structure protruding from the supporting surface to play a supporting role.

[0140] The above-mentioned support plate assembly can be used in conjunction with the above-mentioned medium block clamp. Specifically, in the use process, after the medium block clamp holding the medium block is opened, the medium block is located above the clamp, and the support protrusion of the support plate assembly is facing the medium block and placed on the medium block. The connecting column of the support plate assembly is inserted into the fixed column socket of the clamp, or the fixed column on the clamp is inserted into the connecting column socket of the support plate assembly to position and fix. After fixing, it is flipped over. After flipping over, the support plate assembly is located at the bottom, the clamp is located at the top, the medium block is supported on the support plate assembly, and the clamp is removed to complete the transfer of the medium block.

[0141] By using the above-mentioned dielectric block transfer method, the dielectric block can be transferred without using a clamping tool, which effectively avoids the damage of the impregnation liquid layer caused by the contact between the clamping tool and the dielectric block, thereby improving the metallization effect. In addition, during the transfer process, multiple dielectric blocks can be transferred at the same time without using a clamping tool to transfer the dielectric blocks one by one, which effectively improves the efficiency of the metallization process and increases production capacity.

[0142] The metallization of the dielectric block using the embodiment disclosed in the present application includes the following steps: placing the dielectric block in the placement position of a clamp of a dielectric block clamp, and then fixing and connecting the two clamps. Inserting the clamp holding the dielectric block into the receiving groove of the fixing device, and then placing the fixing device into the bearing frame. Pushing the clamping block on the connecting plate, the through hole on the connecting plate is opened, passing the connecting rod on the bearing frame through the through hole, loosening the clamping block, and completing the clamping of the bearing frame to the connecting plate. The driving rod of the impregnation equipment descends, immersing the bearing frame in the impregnation liquid, and closing the cover plate, starting the vacuum system, and impregnating under vacuum conditions. After the impregnation is completed, the vacuum system is closed. After that, the driving rod rises to make the bearing frame leave the impregnation liquid, rotating the bearing frame to spin dry, opening the solenoid valve, so that the air pressure in the impregnation barrel returns to normal pressure, opening the cover plate, and pushing the clamping block to remove the bearing frame. Take out the fixture and place it on a horizontal surface, remove the clamping plate on the top, place the support surface of the support plate assembly downward on the dielectric block, flip the support plate assembly together with the clamping plate, place the support plate assembly at the bottom, and remove the clamping plate. The dielectric block is placed on the supporting protrusion of the support plate assembly, and the support plate assembly is placed in a drying furnace for drying. Finally, sintering is performed to complete the metal process.

[0143] The beneficial effects that may be brought about by the embodiments of the present application include but are not limited to: (1) The impregnation equipment disclosed in the present application can provide a vacuum environment for the impregnation of dielectric blocks. The suction force generated by the negative pressure can firmly adsorb the impregnation liquid on the surface of the dielectric block and immerse it into the blind holes or small holes of the dielectric block, so that the impregnation effect is better and the metallization processing efficiency is improved. (2) The bearing device used in the impregnation equipment disclosed in the present application can complete the fixed connection between the bearing frame and the connecting plate by only pushing the clamping block; it greatly saves the operation time and improves the metallization efficiency. (3) The impregnation fixing device disclosed in the present application, the objects to be impregnated are respectively fixed in the mutually spaced accommodating grooves, and the objects to be impregnated will not overlap with each other, and a uniform and complete impregnation liquid layer can be formed on the surface of the objects to be impregnated. The dielectric block clamp disclosed in the present application has no contact between the dielectric blocks, so that it can effectively avoid the situation that part of the dielectric block area cannot be covered by the impregnation liquid due to the contact between the dielectric blocks, reduce the situation of uneven impregnation, and improve the impregnation effect. (4) The support plate assembly disclosed in the present application is used for drying the dielectric block. The contact area between the dielectric block and the support plate assembly is extremely small, so that there will be no large-area porcelain exposure. The metal layer of the dielectric block has good integrity, which effectively improves the quality of the resonator.
