While achieving efficient and high-capacity communication, it is required that the modules in the mobile communication system 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 component elements in mobile communication systems. Among them, since the resonant cavities of dielectric filters are filled with materials such as ceramics with high dielectric constant, a microwave wavelength compression effect can be generated, which can greatly compress the effective size of the resonant cavities and miniaturize the overall size of the dielectric filters. A dielectric filter is composed of multiple dielectric resonators, and the dielectric resonators are formed by metallizing the surface of the dielectric blocks. The metallization of the dielectric blocks will affect key performance such as the Q value and reliability of the filter.
[0003] The metallization method of dielectric resonators can adopt the dipping method. An incomplete dipping liquid layer on the surface of the dielectric block during the dipping process will cause gaps in the formed surface metal layer, thereby leaking signal energy, increasing signal attenuation, and affecting the working performance of the dielectric resonator. Summary of the Invention

[0035] To make the objectives, technical solutions and effects of the present application clearer and more definite, the following further describes the present application in detail with reference to the accompanying drawings and by way of examples.
[0036] The preparation process of the dielectric resonator mainly includes steps such as powder preparation, pressing into shape, sintering, metallization, electrode making, SMA (Surface Mount Assembly) patching, and debugging. Powder preparation means grinding and mixing a predetermined amount of powder to obtain powder that meets predetermined conditions; pressing into shape means placing the powder on a mold and extruding it for preliminary shaping to obtain a dielectric block embryo; sintering means placing the dielectric block embryo in a sintering furnace and firing it at a high temperature to obtain a dielectric block; metallization means forming a metal layer on the surface of the dielectric block so that the dielectric block becomes a complete conductor, that is, a dielectric resonator; electrode making means removing a part of the metal layer in a specified area (for example, forming a circular ring shape) so that the dielectric block covered with the metal layer can distinguish between positive and negative electrodes; SMA patching means patching an SMA patch on the dielectric resonator; debugging means grinding the metal layer at the bottom and side walls of the blind holes on the dielectric resonator to debug the filtering performance of the dielectric resonator.
[0037] Among them, the function of metallizing the surface of the dielectric resonator is: to confine the electromagnetic field within the dielectric block and prevent signal spillage, that is, to suppress signal attenuation. The metallization material can be various metal materials or metal composite materials, such as: materials such as silver, copper, aluminum, titanium, tin, gold, etc., or any combination thereof. For the sake of description, the present application takes silver as an example for introduction. It should be noted that the metallization process or equipment disclosed in the present application is not limited to the metallization material being silver.
[0038] Traditional metallization processes mostly adopt the screen printing method. However, due to its own porous and multi-grooved structure and complex structure, the dielectric resonator has higher requirements for the thickness and adhesion of the metal film layer. The metallization method of the dielectric resonator can adopt methods such as dipping method, electroplating method, magnetron sputtering method or welding method to form a metal layer on the surface of the dielectric block. Among them, the dipping method has advantages such as simple process steps and low cost.
[0039] Refer to Figure 1 , Figure 1 is a schematic flow chart of the dipping method according to an embodiment of the present application. As Figure 1 shown, the method includes: a dipping step, a drying step, and a sintering step.
[0040] The impregnation step refers to impregnating the dielectric block in the impregnating solution and then spin-drying it. Specifically, the dielectric block can be placed in a carrying device, immersed in the impregnating solution, and after impregnating for a certain period of time, the carrying device is lifted and spin-silvered.
[0041] The applicant has found in long-term research that the dielectric block itself is relatively small in size and has many chamber blind holes and fine holes. Due to the viscosity of the impregnating solution, when the dielectric block is directly impregnated in the impregnating solution, it is very difficult for the impregnating solution to penetrate into the blind holes and fine holes. For example, the impregnating solution can be 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 relatively high viscosity. The viscosity of the silver paste used for impregnation can be 40-50 dPa·s. The fluidity of the liquid with this viscosity on the surface of the dielectric block is relatively poor, so it is difficult to flow into the blind holes or fine holes of the dielectric block during the impregnation process. In one embodiment, the impregnating solution can be first dropped into the blind holes and holes of the dielectric block, and then the dielectric block is placed in the impregnating solution for silver impregnation. However, this method not only requires adding a large number of drop-hole devices but also consumes more manpower. In addition, during the metallization process of the dielectric block, in order to meet the required metal layer thickness of the product, the metallization process often needs to be repeated, that is, the drop-hole process also needs to be repeated, resulting in a longer production cycle.
[0042] The dielectric block needs to be placed in a carrying device, and after the carrying device is connected and fixed to the impregnating equipment, the impregnation and spin-drying steps are carried out. In one embodiment, the carrying device and the impregnating equipment can be fixed by means of threaded connection. However, this connection method requires the operator to tighten or loosen the screw to complete the connection and separation of the carrying device and the impregnating equipment, which consumes a lot of time and affects the efficiency of the metallization process; moreover, during the process of turning the screw, generally at least two operators are required to cooperate, consuming more manpower.
[0043] The dielectric block can be directly placed in the carrying device for impregnation. However, in this way, the dielectric blocks will be stacked together, and the dielectric blocks will fit together, and it is very difficult for the impregnating solution to penetrate into the mutually contacting parts. Therefore, problems such as uneven coverage of the impregnating solution or no coverage of the impregnating solution in the stacked area are likely to occur, affecting the quality of the dielectric block.
[0044] The drying step refers to drying the impregnating solution on the dielectric block and fixing 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 fixture for drying. However, during the drying process, the contact between the dielectric block and the supporting fixture will cause the wet impregnating solution to adhere to the fixture, resulting in gaps 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 carrying device to the supporting fixture used for drying. For example, clamping tools such as clips or tweezers can be used to transfer the dielectric block. However, during the transfer process, when the clip or tweezer touches the wet impregnating solution, it may scratch the impregnating solution layer on the dielectric block, resulting in unqualified products.
[0047] The silver sintering step refers to putting the dried dielectric block into a sintering furnace to sinter and form a metal layer, which is used to remove organic substances in the metal layer, making the metal layer firmly attached, and finally forming a conductive metal layer. Among them, since organic substances need to be burned during the sintering process, the temperature of the sintering furnace can be 800°C - 900°C.
[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 impregnating equipment is used to impregnate the dielectric block in the impregnating solution so that the surface of the dielectric block is covered with the impregnating solution, and then rotate to shake off the excess impregnating solution on the surface of the dielectric block, so that a uniform wet impregnating solution layer is formed on the surface of the dielectric block.
[0050] The impregnating equipment can include an impregnating chamber and a control device, etc. Among them, the impregnating chamber can be used to carry the impregnating solution and the dielectric block to be impregnated for impregnation; the control device can be used to control the movement of the internal components in the impregnating chamber and can also be used to control the environmental conditions in the impregnating chamber, etc.
[0051] Refer to Figure 2 , Figure 2 is a schematic structural diagram of the impregnating equipment according to an embodiment of the present application. Among them, the impregnating equipment 1 includes an impregnating barrel 11 and a vacuum system 12; the impregnating barrel 11 includes a barrel body 111 and a cover plate 112.
[0052] The impregnating barrel 11 is used to carry the impregnating solution required for impregnation. For example, the impregnating solution can be silver slurry. The impregnating solution has a certain viscosity, and its fluidity is limited by itself.
[0053] Specifically, the barrel body of the impregnating barrel 11 and the cover plate 112 can move relative to each other to realize the opening and closing of the impregnating barrel 11. Specifically, the cover plate 112 can move relative to the impregnating barrel 11 in the axial direction of the impregnating barrel 11 or in a direction perpendicular to the axial direction. When the barrel body 111 and the cover plate 112 are separated, the dielectric block to be impregnated can be put into the impregnating barrel 11 or taken out from the impregnating barrel 11. When the barrel body 111 and the cover plate 112 are closed, a closed space can be formed inside the impregnating barrel 11. The barrel body 111 and the cover plate 112 can be made of materials such as 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 tank 11 to provide a negative pressure environment for the enclosed space inside the impregnation tank 11. The vacuum system 12 may include any applicable air moving components, such as a blower, a vacuum pump, pipes, throttle valves, etc. The vacuum system 12 may be connected to the tank body 111 or to the cover plate 112.
[0055] Specifically, during the use of the above-mentioned impregnation equipment, the article to be impregnated is placed into the impregnation tank 11, then the cover plate 112 is closed, and the vacuum system 12 is started to evacuate the impregnation tank 11, and the article to be impregnated is impregnated in the negative pressure environment.
[0056] The impregnation equipment disclosed in the present application can provide a negative pressure environment when impregnating the dielectric block. The suction force generated by the negative pressure can firmly adsorb the impregnating 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, saving the hole-dropping time before impregnation and reducing the labor and equipment costs at the same time.
[0057] Refer to Figures 3A - 3C , Figure 3A is a schematic structural diagram of an impregnation tank according to an embodiment of the present application. Figure 3B is a schematic axial sectional view of the drive rod according to an embodiment of the present application. Figure 3C is Figure 3A a schematic diagram behind the fixed plate in . Among them, the impregnation tank 11 includes a tank 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 inside the impregnation tank 11 in real time. The pressure detection device 1121 can be any applicable 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 impregnation tank 11 to relieve the negative pressure environment. Specifically, the safety valve can be an electromagnetic valve. In the negative pressure state, the cover plate 112 cannot be separated from the impregnation tank 11. Air needs to be introduced into the impregnation tank 11 to make the pressure inside the tank the same as that outside the tank before the impregnation tank 11 can be opened.
[0060] In one embodiment, a gas guide pipe 1123 penetrating the cover plate 112 is provided on the cover plate 112 for connection with the vacuum system. When the impregnation tank 11 is closed, the vacuum system can extract the gas inside the impregnation tank 11 through the gas guide pipe 1123. It should be noted that the gas guide pipe 1123 can also be provided on the impregnation tank 11 for connection with the 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 open and close the impregnation barrel 11. It should be noted that the driving device 13 can have various implementation manners. 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. 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 drive the impregnation barrel 11 to move. Or, drive the cover plate 112 and the barrel body 111 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 direction perpendicular to 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 above the impregnation 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 impregnation barrel 11. The driving rod 131 can also pass through the cover plate 112 and extend towards the barrel body 111 for connecting with the loading device of the material to be impregnated. The driving rod 131 can drive the loading 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 the loading device of the material to be impregnated. The shape of the fixing portion 1311 can be circular, oval or square. For example, the fixing portion 1311 can be a flange.
[0064] In one embodiment, the driving rod 131 includes a rotating rod 1312 and a sleeve rod 1313. The sleeve rod 1313 is sleeved around the rotating rod 1312, and the sleeve rod 1313 is fixedly connected to the cover plate 112 in a sealed manner. The sleeve rod 1313 and the cover plate 112 can be fixedly connected in a sealed manner by using rubber materials, silica gel materials, etc. Thus, it can prevent gas from entering the impregnation barrel 11 through the gap between the sleeve rod and the cover plate, which is beneficial to forming a closed space when the impregnation 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. Among them, the driving motor 132 is arranged above the impregnation barrel 11 and is connected to the driving rod 131 for driving the driving rod 131 to move or rotate along the axial direction. 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 along the axial direction of the driving rod. Thus, the sleeve rod 1313 can drive the cover plate 112 to move along the axial direction of the driving rod 131 to realize the opening and closing of the impregnation barrel 11.
[0066] Specifically, the rotating rod 1312, the sleeve rod 1313, and the second driving 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 with 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 fixing plate 135, and a lead screw 136 and a first driving motor 1321 are arranged on the back side of the fixing plate 135. The first driving motor 1321 can drive the lead screw 136 to rotate. The nut 137 is sleeved around the lead screw 136, and when the lead screw 136 rotates, the nut 137 can move along the axial direction of the lead screw 136.
[0067] During use, the first driving motor 1321 drives the lead screw 136 to rotate, and the nut 137 moves along the axial direction of the lead screw 136 as the lead screw 136 rotates, thereby driving the sliding plate 134 arranged on the front side of the fixing plate 135, 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 does not drive the sleeve rod 1313 to rotate. A fixing portion 1311 is arranged at one end of the rotating rod 1312 close to the barrel body. Thus, driven by 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. This sealing structure is used to achieve the sealing between the sleeve rod and the rotating rod. For example, the sleeve rod 1313 can be provided with sealing structures 1314 at both ends so that gas cannot enter the impregnation barrel from the gap between the sleeve rod and the rotating rod, which is beneficial to forming a closed space when the impregnation barrel is closed. This sealing structure can be made of rubber material, silicone material, etc. During the impregnation process, the medium block to be impregnated needs to be placed in the impregnation carrier device, and then the impregnation carrier device is fixed in the impregnation equipment before the medium block to be impregnated can be impregnated. The present application discloses a carrier device for an impregnation equipment, which can realize the fixed connection between the carrier device and the impregnation equipment by clamping, with simple operation and can effectively improve the metallization efficiency.
[0070] Refer to Figures 4 - 8 , Figure 4 is a schematic structural diagram of a carrier device for an impregnation equipment according to an embodiment of the present application. Figure 5 is Figure 4 an exploded structural diagram ofFigure 6 It is a schematic diagram of a partial enlarged structure of a connecting part 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 diagram of the structure of a bearing device in an impregnation device according to another embodiment of the present application.
[0071] The impregnation bearing device 2 includes a bearing frame 21, a connecting part 22, and a clamping block 23. It should be noted that the bearing device includes but is not limited to being used for bearing a medium block.
[0072] The connecting part is connected to the impregnation device. The connecting part can be a plate-like structure or a frame structure. The bearing frame 21 includes a frame body 212 and connecting rods 211. There can be one or more connecting rods 211. One end of the connecting rod 211 is connected to the frame body 212, and a clamping groove 2111 is provided at the other end of the connecting rod 211 for connecting with the connecting part 22. The clamping block 23 is movably connected to the connecting part 22, and the clamping block 23 can at least partially embed into the clamping groove 2111 to engage with the connecting rod 211, realizing the connection between the connecting rod 211 and the connecting part 22.
[0073] For the bearing device in the impregnation device disclosed in the present application, only by pushing the clamping block 23 to move so that the clamping block 23 embeds into the clamping groove 2111, the fixed connection between the bearing frame 21 and the connecting part 22 can be completed. The fixing process of the bearing frame 21 and the connecting part 22 does not require operations such as screwing, greatly saving the operation time and improving the metallization efficiency.
[0074] The connecting part 22 includes a connecting plate 221. A through hole 2211 is provided on the connecting plate 221 for accommodating the connecting rod 211 and connecting with the connecting part 22. Among them, 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 an embodiment, the connecting part 22 can be provided with a connecting structure for connecting with the impregnation device. For example, a screw hole or a clamping hole can be provided at the center position of the connecting plate 221. The connecting plate 221 can be connected to a moving device in the impregnation device, so as to drive the bearing frame 21 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, etc. The connecting plate 221 can be square, circular, or oval. For example, the connecting plate 221 can be a flange. A flange refers to a disc-shaped metal body with several fixing holes opened at its periphery for connecting other components.
[0075] The clamping block 23 includes a frame 231 and a clamping groove 232 formed by enclosing the frame 231. The clamping groove 232 includes a first clamping groove 2321 and a second clamping groove 2322 that communicate with each other. The groove width of the first clamping groove 2321 is greater than that 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 form a clamping connection with 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, and the second clamping groove 2322 is embedded into the clamping groove 2111 to complete the clamping.
[0076] In an embodiment, the shape of the second clamping groove 2322 may be similar to the shape of the clamping groove 2111. This enables the clamping block 23 to fit more closely with the connecting rod 211 for clamping. Specifically, if the clamping groove 2111 is square, the clamping block 23 may have a square structure for the second clamping groove 2322. If the clamping groove 2111 is cylindrical, the clamping block 23 may have an arc-shaped structure for the second clamping groove 2322 with a similar or the same radius, such as Figure 7 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 movement range of the clamping block 23. This enables the clamping block 23 to move linearly within a specified range, avoiding the situation where the clamping block 23 is offset due to uneven force.
[0078] The carrying device includes a pushing member 24. The pushing member 24 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 an embodiment, the pushing member 24 includes an elastic member (not shown). The elastic member can be any suitable elastic component. 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 as to push the clamping block 23 to move. The number of elastic members can be one or more. For example, the elastic members can be two, arranged in parallel at both ends of the clamping block 23 perpendicular to the elastic members. The clamping block 23 can be pushed by an external force to move on the connecting portion 22. At the same time, the elastic block deforms during the movement of the clamping block 23. After the external force is cancelled, the clamping block 23 can be pulled back to its initial position by the elastic block.
[0080] In an embodiment, the elastic member is specifically a spring. The spring has advantages such as good energy storage effect, convenient installation, and low cost, 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 upright columns 2123. The upright columns 2123 are located between the two top frames 2121 and the bottom frame 2122, connecting the top frame 2121 and the bottom frame 2122. Herein, the top frame 2121 is the one close to the connecting portion 22, and the bottom frame 2122 is the one far from the connecting portion 22. The top frame 2121 and the bottom frame 2122 are parallel to each other, and the upright columns 2123 are perpendicular to the top frame 2121 / bottom frame 2122. The upright columns 2123 are disposed at the edges and / or centers 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, elliptical, square, etc. The top frame 2121 only includes the edge frame, and the bottom frame 2122 includes the edge frame and load-bearing rods 21221 disposed between the edge frames for loading the articles to be impregnated. The carrier frame 21 can be used to carry a fixing device on which the articles to be impregnated are fixed, etc. Of course, a screen can also be directly coated on the carrier frame 21, and the articles to be impregnated can be directly placed in the carrier frame 21 for impregnation.
[0082] In one embodiment, the connecting rod 211 can be disposed on the top frame 2121 of the carrier frame 21 and be higher than the top frame 2121 of the carrier frame 21. The connecting rod 211 can be fixed to the carrier frame 21 by means of screwing, clamping, welding, etc. For example, as Figure 6 shown, the top frame 2121 of the carrier frame 21 has screw holes, and the connecting rod 211 passes through the screw holes and is fixedly connected to the carrier frame 21 through nuts.
[0083] When the above-mentioned loading device is in use, the sample to be impregnated is placed in the carrier frame 21, and the clamping block 23 is pushed to open the through hole 2211. At this time, the elastic member is compressed. The connecting rod 211 on the carrier frame 21 is passed through the through hole 2211, and then the clamping block 23 is released. The elastic member rebounds, pushing the clamping block 23 to move above the through hole 2211 and be clamped with the clamping groove 2111 of the connecting rod 211 to fixedly connect the carrier frame 21 and the connecting portion 22. In the clamped state, the thicker end of the connecting rod 211 is placed above the connecting portion 22, and the thinner area of the connecting rod 211 is clamped between the side walls of the clamping groove 232 and the side wall of the clamping block 23, so that the carrier frame 21 and the connecting portion 22 are fixedly connected.
[0084] Refer to Figure 8, in one embodiment, the carrying device is further provided with a protective cover 25, which is connected to the fixing part and is used to accommodate at least part of the clamping block 23 and the pushing member 24. Specifically, the protective cover 25 is disposed 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 side shell walls 252. The upper shell wall 251 may cover the elastic member and a partial area of the clamping block 23. The side shell walls 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 may 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 separate from the connecting part 22.
[0085] In one embodiment, the connecting part 22 may be connected to a connecting rod 211 in the impregnation device. Specifically, the connecting part 22 is connected to a fixing disk at the end of the connecting rod 211, and the connection method may include screwing, clamping or welding. Driven by the connecting rod 211, the carrying device can be driven to move up and down or rotate. Of course, the connecting part 22 of the carrying device and the fixing disk at the end of the connecting rod 211 may be the same component, that is, the connecting part 22 of the carrying device is directly connected and fixed to the connecting rod 211.
[0086] The present application discloses an impregnation fixing device, which can isolate the articles to be impregnated from each other, so as to solve the problem of uneven impregnation caused by the mutual stacking of the articles to be impregnated during the impregnation process. The articles to be impregnated may refer to the articles themselves or the fixtures for clamping the articles, such as dielectric blocks or the fixtures for clamping dielectric blocks. For the sake of convenience of description only, the present application takes the article to be impregnated as a dielectric block as an example for illustration. It should be noted that the impregnation fixing device disclosed in the present application is not limited to being used for fixing dielectric blocks or the fixtures for clamping dielectric blocks.
[0087] Refer to Figure 9 、 Figure 10 , Figure 9 is a schematic structural view of an impregnation fixing device according to an embodiment of the present application. Figure 10 is a schematic structural view of a support plate according to an embodiment of the present application.
[0088] The impregnation fixing device 3 includes a housing rack 31 and at least one support plate 32. The housing rack 31 includes a supporting bottom plate 311 and supporting rods 312; at least one support plate 32 is fixed on the supporting rods 312, is stacked and spaced apart from the supporting bottom plate 311, and a plurality of accommodation grooves 321 are provided on the support plate 32, and the accommodation grooves 321 are used to accommodate the articles to be impregnated.
[0089] Among them, the supporting bottom plate 311 plays a supporting role and is mainly used to support the articles to be impregnated, such as the dielectric block or the fixture for clamping the dielectric block. In one embodiment, the supporting bottom plate 311 can be made of metal materials, such as alloy steel, aluminum alloy or stainless steel, etc. The shape of the supporting bottom plate 311 can be polygonal, circular or elliptical, etc. 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, and the hollow area 3111 and the accommodating groove 321 partially overlap or do not overlap in the orthographic projection on the supporting bottom plate 311. During the impregnation process, the dielectric block needs to be impregnated in the impregnating solution. The supporting bottom plate 311 being set as a hollow plate can enable the impregnating solution to directly contact the article to be impregnated 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 impregnating solution can pass through the supporting bottom plate 311 to directly contact the article to be impregnated during the impregnation process.
[0091] The support rod 312 plays a supporting role and a fixing role. The support rod 312 can be made of materials such as alloy steel, aluminum alloy or stainless steel. The support rod 312 and the supporting bottom plate 311 can be detachably connected or non-detachably connected. Specifically, the support rod 312 can be non-detachably connected to the supporting bottom plate 311 by means of welding or bonding, or can be detachably connected to the supporting bottom plate 311 by means of screwing or clamping. The support rod 312 can be perpendicular to the bottom plate. For example, when the bottom 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 on the support plate 32, the number of support rods 312 is reduced, effectively reducing the processing cost of the accommodating rack 31.
[0093] The support rod 312 is provided with a limiting structure for limiting the position of the support plate 32 on the accommodating rack 31. Specifically, the support rod 312 can be tapered step by step in the extending direction from the supporting bottom plate 311, so that the support plate 32 can be limited and cannot slide towards the supporting bottom plate 311. The limiting structure can also be any other structure that can play a role in limiting the position of the support plate 32, such as a card slot, a clip, a limiting protrusion, etc. The support rod 312 can be made of materials such as alloy steel, aluminum alloy or stainless steel.
[0094] The accommodating groove 321 is used to accommodate the articles to be impregnated, such as the dielectric block or the fixture for clamping the dielectric block. The accommodating groove 321 is a through groove penetrating the support plate 32, so that the article to be impregnated is clamped in the accommodating groove 321 and abuts against the supporting bottom plate 311. Therefore, the shape and size of the accommodating groove 321 can be determined according to the shape and size of the article to be accommodated. For example, the accommodating groove 321 can be rectangular.
[0095] The shape of the support plate 32 can be square or circular. In an embodiment, the support plate 32 is circular, and the accommodating 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 articles to be impregnated do not affect each other, and at the same time, the number of the accommodating grooves 321 can be as large as possible.
[0096] In an embodiment, refer to Figure 9 , the support plate 32 is circular, the extension line of the accommodating groove 321 can pass through the center of the circle, and the position of the accommodating groove 321 coincides with the radius of the support plate 32. This arrangement can, while ensuring the number of the accommodating grooves 321, maximize the distance between the accommodating grooves 321 as much as possible, thereby reducing the mutual influence between the accommodated dielectric blocks during the impregnation and spin-drying processes.
[0097] In an embodiment, refer to Figure 10 , the support plate 32 can also be circular, the extension line of the accommodating groove 321 does not pass through the center of the circle, and has a certain included angle with the radius of the support plate 32. The included angles between the extension lines of all the accommodating grooves on the support plate 32 and the radius of the support plate 32 are the same. This arrangement can reduce the included angle between the accommodating groove and the tangent of the support plate 32, thereby reducing the mutual interference between the accommodated articles 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 articles 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, the two support plates 32 are stacked and arranged at intervals, and the accommodating grooves 321 penetrating the support plates 32 are provided on both support plates 32. The accommodating grooves 321 of the two support plates 32 are arranged opposite to each other, so that the article to be impregnated passes through the accommodating groove 321 and is clamped between the two support plates 32. Therefore, multi-stage fixation of the article to be impregnated (dielectric block or fixture for clamping the dielectric block) can be realized. The multi-stage fixation method can effectively improve the stability of the article to be impregnated placed on the impregnation fixing device 3, and prevent the article to be impregnated from falling off the impregnation fixing device 3 during the impregnation process, affecting the metallization effect.
[0099] In one embodiment, the number of the support plates 32 is two, which are respectively arranged at positions close to the top end and the bottom end of the support rod 312. Thus, the upper and lower parts of the article to be impregnated can be fixed, so as to ensure that the article to be impregnated will not fall off the impregnation fixing device 3 when the impregnation fixing device 3 rotates or moves up and down. At the same time, only two support plates 32 can reduce the manufacturing cost of the impregnation fixing device 3.
[0100] The support plate 32 can also be provided with a first limiting structure 322 that cooperates with the limiting device of the support rod 312, such as a through hole. The arrangement positions of the first limiting structure 322 on the support plate 32 correspond to the arrangement positions of the support rod 312. The support plate 32 can be made of materials such as alloy steel, aluminum alloy or stainless steel. When the above-mentioned impregnation fixing device 3 is used, the article to be impregnated (medium block or fixture for clamping the medium block) needs to be inserted into a plurality of correspondingly connected accommodation grooves 321, and the plurality of connected accommodation grooves 321 are respectively arranged on a plurality of support plates 32, so that the article to be impregnated contacts the supporting bottom plate. Thus, the bottom surface of the article to be impregnated is supported on the supporting bottom plate 311, and the side wall of the article to be impregnated passes through a plurality of correspondingly connected accommodation grooves 321 to realize multi-stage fixing of the article to be impregnated, effectively improving the stability of the article to be impregnated during impregnation or drying. In addition, since the articles to be impregnated are respectively fixed in the mutually spaced accommodation grooves 321, the articles to be impregnated do not overlap each other, and the articles to be impregnated can be in full contact with the impregnation liquid, and a uniform and complete impregnation liquid layer can be formed on the surface of the articles to be impregnated, improving the impregnation effect.
[0101] In one embodiment, the impregnation fixing device 3 is further provided with a second limiting structure 33 for limiting the position of the impregnation fixing device 3 when it is connected and fixed to the impregnation equipment, so as to drive the displacement of the impregnation fixing device 3. Specifically, the second limiting structure 33 can include a clamping groove 331 arranged at the edges of the support plate 32 and the supporting bottom plate 311 and a positioning hole 332 arranged at the centers of the support plate 32 and the supporting bottom plate 311.
[0102] The impregnation fixing device 3 can be placed in the aforementioned carrying frame, wherein the second limiting structure 33 can be used to limit the position of the impregnation fixing device 3 in the carrying frame so that it will not slide in the carrying frame. And the second limiting structure 33 can also drive the impregnation fixing device 3 to rotate along with the carrying frame. Specifically, the column 2123 arranged at the center of the carrying frame can pass through the positioning hole 332 at the centers of the support plate 32 and the supporting bottom plate 311 to limit the position of the impregnation fixing device 3 in the carrying frame. The column 2123 of the carrying frame can also be provided with a limiting protrusion for cooperating with the clamping groove 331 arranged at the edges of the support plate 32 and the supporting bottom plate 311, so that the impregnation fixing device 3 will not rotate relative to the carrying frame.
[0103] The present application discloses a dielectric block fixture, which can isolate dielectric blocks from each other, thereby solving the problem of uneven impregnation caused by mutual stacking of dielectric blocks during the impregnation process. In addition, the dielectric blocks are fixed in the dielectric block fixture. When the dielectric blocks are taken out of the impregnation device, the clamping tool does not need to directly contact the dielectric blocks, thereby avoiding the situation where the clamping tool damages the impregnation liquid layer on the surface of the dielectric blocks.
[0104] Refer to Figures 11 - 13 , Figure 11 which is a schematic structural view of a dielectric block fixture according to an embodiment of the present application. Figure 12 which is a schematic structural view of a splint according to an embodiment of the present application. Figure 13 which is a partially enlarged schematic structural view of a carrier table according to an embodiment of the present application. It should be noted that the dielectric blocks disclosed in the present application are not limited to being used for clamping dielectric blocks for impregnation.
[0105] The dielectric block fixture 4 includes at least two splints 41, which are movably connected between the splints 41, and the dielectric blocks 6 can be fixed between the two splints 41. Of course, the dielectric block fixture 4 can also include three or more splints 41, and the dielectric blocks 6 can be fixed between adjacent two splints 41. The splints 41 can be made of a metal material or a polymer material with a certain strength.
[0106] Each splint 41 includes: a placement position 411 and at least two carrier tables 412. The placement position 411 is surrounded by a plurality of frame bars 413 connected in sequence for accommodating the dielectric blocks 6. That is, the placement position 411 is a frame structure with a hollow interior. At least two carrier tables 412 are arranged on the frame bars 413 and at the bottom of the placement position 411. The two carrier tables 412 can be arranged on the frame bars 413 opposite to each other, and the carrier tables 412 are used to prevent the dielectric blocks 6 from leaking out of the placement position 411. The placement positions 411 of at least two splints 41 are arranged opposite to each other to clamp the dielectric blocks 6 by using the carrier tables 412 on the splints 41. When the two splints 41 are closed, the two placement positions 411 can form an accommodation cavity, the dielectric blocks 6 are located in the accommodation cavity, and the carrier tables 412 in the two placement positions 411 clamp both sides of the dielectric blocks 6 to fix the dielectric blocks 6.
[0107] When the above-mentioned dielectric block fixture 4 is used, the splints 41 of the dielectric block fixture 4 are separated, one splint 41 is placed horizontally with the carrier table 412 below, and the dielectric blocks 6 are respectively placed on the carrier tables 412 in the hollow parts of the splint 41; another splint 41 is placed on the dielectric blocks 6, and the carrier table 412 of the other splint 41 is above. The two splints 41 are fixedly connected, and the dielectric blocks 6 are clamped between the two splints 41.
[0108] In the embodiments disclosed in the present application, the dielectric blocks 6 can be fixed in the fixture 4, and there is no contact between the dielectric blocks 6, so that it is possible to effectively avoid the situation that some areas of the dielectric blocks 6 cannot be covered by the impregnating liquid due to the mutual contact of the dielectric blocks 6, reduce the uneven impregnation, and improve the impregnation effect. In addition, the dielectric blocks 6 are fixed in the placement positions 411 by using the carrier table 412. The placement positions 411 are of a frame structure, which can reduce the contact area between the fixture 4 and the dielectric blocks 6, so that the impregnating liquid can better contact the dielectric blocks 6.
[0109] The frame bar 413 includes a frame 4131 that encloses and forms the clamping plate 41 and a partition bar 4132 connected to the frame 4131. The partition bar 4132 is used to divide the clamping plate 41 into a plurality of placement positions 411.
[0110] Among them, the frame 4131 includes a first frame, a second frame, a third frame, and a fourth frame. The four frames are connected end to end. The partition bar 4132 straddles between the first frame and the third frame or between the second frame and the fourth frame. A plurality of partition bars 4132 are arranged parallel to each other and are perpendicular to the frame 4131 they straddle. There is a placement position 411 between every two adjacent partition bars 4132. A plurality of placement positions 411 are arranged parallel to each other. When the two clamping plates 41 are closed, the dielectric blocks 6 can be fixed in the placement positions 411.
[0111] In one embodiment, a plurality of liquid leakage grooves 414 are provided on the side of the frame bar 413 away from the carrier table 412 for allowing the impregnating liquid to flow into the fixture 4 and contact the dielectric blocks 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 impregnating liquid can enter the fixture 4 from the through holes, so that all sides of the dielectric blocks 6 are easily contacted by the impregnating liquid. Specifically, a first liquid leakage groove 4141 is provided on the frame 4131 perpendicular to the partition bar 4132, and the first liquid leakage groove 4141 can be provided between two partition bars 4132. At least one second liquid leakage groove 4142 is provided on each partition bar 4132, so that liquid leakage grooves 414 are provided on the frame bars 413 around each placement position 411. The widths 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 to prevent the dielectric block 6 from falling from the liquid leakage groove 414. In addition, a third liquid leakage groove 4143 is also provided at the connection of the frame bars 413 around each placement position 411 to facilitate the impregnating liquid to flow into the fixture 4 and contact the dielectric blocks 6. Thus, the corners of the dielectric blocks 6 can also be fully contacted by the impregnating liquid, avoiding dead corners.
[0112] In one embodiment, an isolation protrusion 415 is provided on each side of the frame bar 413 facing the inner side of the placement position 411. The isolation protrusion 415 is in direct contact with the medium block 6 and is used to reduce the contact area between the frame bar 413 and the medium block 6. The isolation protrusion 415 can effectively avoid the problem that it is difficult to cover the impregnating liquid in some areas of the medium block 6 due to the side surface of the medium block 6 being in close contact with the frame bar 413. Specifically, a number of first isolation protrusions 4151 are provided on the opposite sides between the plate frames 4131, and a number 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. To further optimize the isolation effect, each side of the frame bar 413 around each placement position 411 includes at least two isolation protrusions 415, so that the medium block 6 can be kept stable.
[0113] In one embodiment, a number of fixing members 416 are provided on the side of the plate frame 4131 away from the bearing platform 412. The fixing members 416 are grooves or protrusions and are used for snap connection with corresponding protrusions or grooves. The fixing members 416 include multiple groups of fixing components. Each group of fixing components includes a cooperating fixing post 4161 and a fixing post insertion hole 4162. The multiple groups of fixing components are arranged in pairs on the opposite sides of the frame bar 413. The fixing members 416 are used to fix the two clamping plates 41 when the two clamping plates 41 are closed. The shape of the fixing post insertion hole 4162 can be determined according to the fixing post 4161. For example, the fixing post 4161 can be a screw, and the fixing post insertion hole 4162 can have a threaded structure. Another example is that the fixing post 4161 can be a pin, and the fixing post insertion hole 4162 has a structure for cooperating with the pin.
[0114] In one embodiment, there are multiple bearing platforms 412, which are respectively arranged on the surrounding frame bars 413 of the placement position 411 and at the corners where the two frame bars 413 are connected. The bearing platform 412 is connected to the plate frame 4131 and / or the partition rod 4132. A third isolation protrusion 4153 is also provided on the surface of the bearing platform 412 in contact with the medium block 6, which is used to reduce the contact area between the medium block 6 and the bearing platform 412, so that the medium block 6 can fully contact the impregnating liquid. The bearing platform 412 can also be provided with liquid leakage holes 4121, which are convenient for the impregnating liquid to flow into the fixture 4 from the liquid leakage holes 4121 and contact the medium block 6. Specifically, the liquid leakage holes 4121 can be provided at the connection between the plate frame 4131 and the partition rod 4132 and communicate with the liquid leakage groove 414.
[0115] The medium block fixture 4 disclosed in the present application is provided with multiple liquid leakage grooves 414 or liquid leakage holes 4121, which can facilitate the impregnating liquid to enter the medium block fixture 4 and fully contact all surfaces of the medium block 6. At the same time, the fixture is provided with multiple isolation protrusions 415, which are used to reduce the contact area between the medium block 6 and the fixture 4, thereby avoiding the uneven impregnation caused by the contact between the medium block 6 and the fixture 4.
[0116] The above-mentioned medium block fixture can be used in conjunction with the carrying device of the aforementioned impregnation equipment. Specifically, the medium block is clamped in the medium block fixture, and the medium block fixture with the clamped medium block is directly placed into the carrying frame of the carrying device. After the carrying frame is fixedly connected to the connecting part, the subsequent impregnation process is carried out.
[0117] The above-mentioned medium block fixture can also be used in conjunction with the aforementioned fixing device. Specifically, the medium block is clamped in the medium block fixture, and the medium block fixture with the clamped medium block is inserted into the accommodating groove of the fixing device. Then, the fixing device is placed into the impregnation equipment for the subsequent impregnation process.
[0118] The above-mentioned medium block fixture can also be used in conjunction with the aforementioned fixing device and carrying device. Specifically, the medium block is clamped in the medium block fixture, and the medium block fixture with the clamped medium block is inserted into the accommodating groove of the fixing device. Then, the fixing device is placed into the carrying frame of the carrying device. After the carrying frame is fixedly connected to the connecting part, the subsequent impregnation process is carried out.
[0119] The above-mentioned medium block fixture can also be used in conjunction with the aforementioned fixing device, carrying device, and impregnation equipment. Specifically, the medium block is clamped in the medium block fixture, and the medium block fixture with the clamped medium block is inserted into the accommodating groove of the fixing device. Then, the fixing device is placed into the carrying frame of the carrying device. After the carrying frame is fixedly connected to the connecting part, the impregnation barrel of the impregnation equipment is closed, evacuated, and the subsequent impregnation process is carried out.
[0120] This application discloses a supporting and placing plate assembly, which can be used to support and place medium blocks during the drying process after impregnation, can reduce the damage to the metal layer caused by contact with the supporting and placing plate assembly during the drying process, and improve the metallization quality of the medium blocks.
[0121] Refer to Figures 14 - 17 , Figure 14 which is a schematic structural diagram of the supporting and placing plate assembly according to an embodiment of the present application. Figure 15 which is a schematic structural diagram of the supporting and placing plate assembly according to another embodiment of the present application. Figure 16 is Figure 15 exploded view of Figure 17 which is a schematic structural diagram of the supporting protrusion according to an embodiment of the present application.
[0122] The supporting and placing plate assembly 5 is used to support and place the medium block 6 during the drying process. The supporting and placing plate assembly 5 includes a supporting and placing plate 51, and the supporting and placing plate 51 includes an opposite supporting surface and a bottom surface; a plurality of supporting protrusions 52 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 respectively support the four corners of the dielectric block 6.
[0124] In the embodiments disclosed in the present application, the dielectric block 6 is supported by the support protrusion 52, and the contact area between the dielectric block 6 and the placement plate is extremely small. During the drying process, since the contact between the dielectric block 6 and the placement plate causes a very small exposed porcelain area, there will be no phenomenon of large-area exposed porcelain. The integrity of the metal layer of the dielectric block 6 is good, effectively improving the quality of the resonator.
[0125] In one embodiment, the placement plate 51 includes a peripheral frame 511 and an internal hollow area 512, and the support protrusion 52 is provided on the frame 511. By providing the hollow structure, not only can the heat energy absorbed by the placement plate 51 in the drying equipment be reduced, but also the heat conduction during the drying process of the dielectric block 6 can be made smoother, making the drying more thorough.
[0126] The placement plate 51 is further provided with a partition strip 513 connecting the frame 511. The partition strip 513 is used to divide the hollow area 512 into multiple areas, and the support protrusion 52 is provided on the partition strip 513.

Specifically, the placement plate 51 can be rectangular, and the partition strip 513 is parallel to the long side or the short side of the frame 511.
[0127] For example, as Figure 14 shown, the number of partition strips 513 is two, and the partition strips 513 are parallel to the long side of the frame 511. The dielectric blocks can be arranged in a row on the placement plate 51, and the arrangement direction of the dielectric blocks is parallel to the long side of the frame 511.
[0128] For another example, as Figure 15 shown, the number of partition strips 513 is four, and the partition strips 513 are parallel to the short side of the frame 511 of the placement plate 51. The dielectric blocks can be arranged in two rows on the placement plate 51, and the arrangement direction between the rows is parallel to the long side of the frame 511. The arrangement direction of the dielectric blocks in each row is parallel to the short side of the frame 511.
[0129] For another example, the number of the isolation strips 513 is two, and the isolation strips 513 are parallel to the short sides of the frame 511 of the placement plate 51. The dielectric blocks can be arranged in two columns on the placement 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 within the frame 511 and 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 parallel sides of the frame 511 or two perpendicular sides of the frame 511. The arrangement of the dielectric blocks 6 can be determined according to the arrangement direction of the isolation strips 513.
[0131] The placement plate assembly 5 further includes a fixed bottom plate 53, and the fixed bottom plate 53 is arranged on the bottom surface of the placement plate 51 and is used for fixing the support protrusions 52 on the placement plate 51.
[0132] In an embodiment, the fixed bottom plate 53 is detachably connected to the placement plate 51. The connection manner between the fixed bottom plate 53 and the placement plate 51 can be snap connection, pin connection or screw connection, which is not limited herein. The fixed bottom plate 53 and the placement plate 51 can be provided with corresponding structures for connection and fixation. For example, the fixed bottom plate 53 and the placement plate 51 can be connected by screws, and the fixed bottom plate 53 and the placement plate 51 are provided with a plurality of threaded holes 515 for the screws to pass through to fix the fixed bottom plate 53 and the placement plate 51. The fixed bottom plate 53 and the placement plate 51 have the same shape and size. Of course, the fixed bottom plate 53 can also be multiple strip-shaped plates, which are respectively fixed to the area of the placement plate 51 where the support protrusions 52 are provided.
[0133] In an embodiment, a plurality of through holes 514 are provided on the placement plate 51, and a plurality of support protrusions 52 respectively pass through the through holes 514 and are fixed to the placement plate 51.
[0134] In an embodiment, the support protrusion 52 includes a nail head 521, a nail rod 522 and a nail tip 523. The nail tip 523 is conical, with a gradually decreasing diameter, and the end with a smaller diameter is pointed, and its larger diameter end is 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 placement plate 51, and the nail head 521 is located between the placement plate 51 and the fixed bottom plate 53 to fix the support protrusion 52. The placement plate 51 and the fixed bottom plate 53 are fixedly connected, and the top cap of the support protrusion 52 is clamped between the placement plate 51 and the fixed bottom plate 53, so that the support protrusion 52 is fixed. When the placement plate 51 is separated from the fixed bottom plate 53, the support protrusion 52 can be taken out. When the support protrusion 52 is damaged, the damaged support protrusion 52 can be taken out and replaced, which can effectively extend the service life of the placement plate 51 and save costs.
[0136] In one embodiment, referring to Figure 17 , the nail rod 522 is provided with an avoidance groove 5221, and the avoidance groove 5221 is located at the connection between the nail rod 522 and the nail tip 523 for avoiding contact between the nail rod 522 and the dielectric block. Specifically, a groove is provided in the area of the nail rod 522 close to 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 in a mushroom shape covering the nail rod 522.
[0137] A plurality of blind holes are provided on the surface of the dielectric block 6, and after metallization, the dielectric block 6 can be debugged by grinding the metal layer at the bottom of the blind hole. Therefore, when drying, positioning the contact point between the support protrusion 52 and the dielectric block 6 in the blind hole 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 carrying the dielectric block 6, the entire area of the nail tip 523 is located in the blind hole of the dielectric block 6. When the dielectric block 6 shakes slightly on the placement 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 there is adhesion of the impregnating liquid, the exposed magnetic area is very small after the dielectric block 6 is separated, ensuring the quality of metallization of the dielectric block 6.
[0139] In one embodiment, a plurality of connectors 54 are further provided on the placement surface of the placement plate 51. The connectors 54 are grooves or protrusions for snap-connecting with corresponding protrusions or grooves. The connectors 54 include multiple groups of connection components, and each group of connection components includes a mutually cooperating connection post 541 and a connection post socket 542. The multiple groups of connection components are arranged in pairs on opposite sides of the bearing surface. In each group of connection components, the connection post 541 and the connection post socket 542 are respectively arranged on the two opposite sides of the bearing surface. Thus, when the dielectric block 6 is transferred between two placement plates 51, the two placement plates 51 are buckled, and the connection post 541 can be inserted into the connection post socket 542, thereby playing a positioning role. The connection post socket 542 can also be a boss structure protruding from the placement surface to play a supporting role.
[0140] The above-mentioned placing plate assembly can be used in cooperation with the aforementioned medium block fixture. Specifically, during the use process, after opening the medium block fixture clamping the medium block, the medium block is located above the clamping plate. The support protrusion of the placing plate assembly is oriented towards the medium block and placed on the medium block. The connecting column of the placing plate assembly is inserted into the fixing column insertion hole of the clamping plate, or the fixing column on the clamping plate is inserted into the connecting column insertion hole of the placing plate assembly for positioning and fixing. After fixing, it is flipped. After flipping, the placing plate assembly is located below, the clamping plate is located above, and the medium block is placed on the placing plate assembly. Then the clamping plate is removed, and the transfer of the medium block is completed.
[0141] Through the above-mentioned medium block transfer method, the transfer of the medium block can be completed without using a clamping tool, effectively avoiding the damage of the impregnation liquid layer caused by the contact between the clamping tool and the wet impregnation liquid layer of the medium block, and improving the metallization effect. In addition, during the transfer process, multiple medium blocks can be transferred simultaneously without using a clamping tool to transfer the medium blocks one by one, effectively improving the efficiency of the metallization process and increasing the production capacity.
[0142] Using the embodiments disclosed in the present application for medium block metallization includes the following steps: placing the medium block in the placement position of one clamping plate of the medium block fixture, and then fixedly connecting the two clamping plates. Inserting the fixture clamping the medium block into the accommodation groove of the fixing device, and then placing the fixing device into the carrying frame. Pushing the clamping block on the connecting plate, the through hole on the connecting plate is opened, passing the connecting rod on the carrying frame through the through hole, and loosening the clamping block to complete the clamping of the carrying frame to the connecting plate. The driving rod of the impregnation device descends, immersing the carrying frame in the impregnation liquid, closing the cover plate, starting the vacuum system, and performing impregnation under vacuum conditions. After impregnation is completed, the vacuum system is closed. Then the driving rod rises to make the carrying frame leave the impregnation liquid, rotating the carrying frame to spin dry, opening the solenoid valve to make the air pressure in the impregnation barrel return to normal pressure, opening the cover plate, and pushing the clamping block to remove the carrying frame. Taking out the fixture and placing it on a horizontal plane, removing the clamping plate located above, placing the placing surface of the placing plate of the placing plate assembly downward on the medium block, flipping the placing plate assembly and the clamping plate together, placing the placing plate assembly below, and removing the clamping plate. The medium block is placed on the support protrusion of the placing plate assembly, and the placing plate assembly is placed in a drying oven 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 impregnating the dielectric block. The suction force generated by negative pressure can firmly adsorb the impregnating liquid on the surface of the dielectric block and immerse it into the blind holes or small holes of the dielectric block, resulting in a better impregnation effect and improving the metallization processing efficiency. (2) For the carrying device in the impregnation equipment disclosed in the present application, only by pushing the clamping block can the fixed connection between the carrying frame and the connecting plate be completed; this greatly saves operation time and improves the metallization efficiency. (3) For the impregnation fixing device disclosed in the present application, the articles to be impregnated are respectively fixed in the accommodating grooves at intervals, and the articles to be impregnated do not overlap each other, and a uniform and complete impregnating liquid layer can be formed on the surface of the articles to be impregnated. For the dielectric block fixture disclosed in the present application, there is no contact between the dielectric blocks, so that it can effectively avoid the situation that some areas of the dielectric blocks cannot be covered by the impregnating liquid due to the mutual contact of the dielectric blocks, reduce the uneven impregnation, and improve the impregnation effect. (4) The placing plate assembly disclosed in the present application is used for drying the dielectric block. The contact area between the dielectric block and the placing plate assembly is extremely small, so that there will be no phenomenon of large-area porcelain exposure, and the integrity of the metal layer of the dielectric block is good, effectively improving the quality of the resonator.
