AI Technical Summary
Existing suction hole fixtures require a large flow suction pump when processing large-size or multi-hung porcelain substrates, resulting in an increase in production costs. However, when processing small-size or few-hung porcelain substrates, the substrate is easily deformed, and the product quality cannot be guaranteed.
A metallized suction hole fixture of ceramic casting sheet is designed. By installing the current limiting push plate and the leakage plate on the top of the cavity, the sliding cooperation between the current limiting push plate and the leakage plate is used to form an appropriate slurry flow channel, and flow adjustment is achieved in combination with the suction pump. It is suitable for raw ceramic substrates of different sizes and number of hanging holes.
Without replacing the cavity and suction pump, effective hole wall metallization of the raw ceramic substrates of different sizes and number of hanging holes is achieved, which improves production efficiency, reduces production costs, and ensures product quality.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ceramic package production and processing, in particular to a metallized suction hole fixture for ceramic tape. Background Art
[0002] The suction hole fixture is mainly used for suction holes after hanging holes in the production of green ceramics for ceramic packages. By discharging the excess slurry in the holes and only retaining the slurry adsorbed on the hole walls, the effect of hole wall metallization is achieved.
[0003] For the existing suction hole fixtures, the slurry is mainly pumped away by a large-flow suction system to achieve hole wall metallization. The suction hole equipment mainly consists of a green ceramic substrate, a leak plate, a cavity and a special suction pump. The leak plate is fixed on the cavity through positioning pin columns, and the green ceramic substrate is positioned through positioning pin columns, forming a slurry flow channel between the substrate, the leak plate and the cavity, and the slurry is pumped away through the suction system.
[0004] However, for the existing such suction hole fixtures, for large-size green ceramic substrates and green ceramic substrates with a large number of hanging holes, a large-flow suction pump and a cavity are required, which increases the production cost. For small-size green ceramic substrates and green ceramic substrates with a small number of hanging holes, using a large-flow suction pump will cause deformation of the green ceramic substrates and the product quality cannot be guaranteed. Therefore, a metallized suction hole fixture for ceramic tape is needed, which is suitable for the production of hole wall metallization of green ceramic substrates with different sizes and different numbers of hanging holes. Without replacing the cavity and the suction pump, by pushing the flow-limiting push plate, the suction flow requirements of green ceramic substrates with different sizes and different numbers of hanging holes can be reduced, while ensuring the product quality, improving the efficiency and reducing the later production cost. Summary of the Utility Model
[0005] In order to solve the technical problem that for the existing such suction hole fixtures, for large-size green ceramic substrates and green ceramic substrates with a large number of hanging holes, a large-flow suction pump and a cavity are required, which increases the production cost, and for small-size green ceramic substrates and green ceramic substrates with a small number of hanging holes, using a large-flow suction pump will cause deformation of the green ceramic substrates and the product quality cannot be guaranteed, the utility model provides a metallized suction hole fixture for ceramic tape.
[0006] The utility model is realized by adopting the following technical solutions: A metallized suction hole fixture for ceramic tape includes a cavity and a suction pump. A cavity opening is provided at the top of the cavity. Two groups of leak plates are installed at the top of the cavity opening. A flow-limiting push plate is slidably installed in the sandwich gap between the two groups of leak plates. A plurality of leak holes are distributed and penetrated through the top of the leak plate. Two groups of limiters are distributed and installed at both ends of the flow-limiting push plate. A flow-limiting opening is penetrated through the top of the flow-limiting push plate.
[0007] Preferably, the leak plate covers the top opening of the cavity opening, and the opening size of the flow-limiting opening is one-third of the opening size of the cavity opening.
[0008] Preferably, a plurality of groups of pin holes are distributed on the top of the cavity opening, pins are installed on the inner walls of the pin holes, and the two groups of leak plates are installed on the top of the cavity opening by means of pin limiters.
[0009] Preferably, a connection port is installed on one side outer wall of the cavity, and one end of the connection port is connected to the internal cavity of the cavity.
[0010] Preferably, the external port of the connecting port is connected to the suction pump via a connecting pipe, and a valve switch is installed on the connecting pipe.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] During use of the utility model, the staff can use the two groups of leak plates to cooperate with the pin holes and the pins to install the current limiting push plate between the two groups of leak plates, and then use the pins to position the raw ceramic substrate with the pin holes above the top group of leak plates. The staff can pull the current limiting push plate to slide relative to the two groups of leak plates through the limiter to drive the current limiting opening to move to an appropriate position, and cooperate with the leak holes on the two groups of leak plates and the number of hanging holes of different sizes on the raw ceramic substrate to form a slurry flow channel between the raw ceramic substrate, the leak plates, the current limiting push plate, and the cavity. The excess hanging hole slurry on the raw ceramic substrate is sucked away by a suction pump, thereby achieving the effect of hole wall metallization. Therefore, without replacing the cavity and the suction pump, the demand for suction flow of raw ceramic substrates with different sizes and different numbers of hanging holes can be reduced by pushing the current limiting push plate. The utility model is suitable for the production of hole wall metallization of raw ceramic substrates of different sizes and different numbers of hanging holes, and improves the practicality of the overall suction hole clamp, while ensuring product quality, improving efficiency, and reducing later production costs.

[0019] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.
[0020] Please refer to Figure 1 - Figure 5 , a metalized suction hole fixture for ceramic tape of this embodiment includes a cavity 1 and a suction pump 7. A cavity opening 2 is provided at the top of the cavity 1. Two groups of leakage plates 3 are installed at the top of the cavity opening 2. A current-limiting push plate 4 is slidably installed in the sandwich gap between the two groups of leakage plates 3. A plurality of leakage holes 301 are distributed and penetrated through the top of the leakage plate 3. The arrangement manner of the leakage holes 301 depends on the layout manner of the production product. Two groups of limiters 401 are distributed and installed at both ends of the current-limiting push plate 4. A current-limiting opening 402 is penetrated through the top of the current-limiting push plate 4;
[0021] Further, a plurality of pin holes are distributed at the top of the cavity opening 2. A pin 5 is installed on the inner wall of the pin hole. The two groups of leakage plates 3 are installed at the top of the cavity opening 2 by being limited by the pin 5. The leakage plate 3 covers the top opening of the cavity opening 2. The opening size of the current-limiting opening 402 is one-third of the opening size of the cavity opening 2;
[0022] Further, a connection port 6 is installed on the outer wall of one side of the cavity 1, and one end of the connection port 6 is communicated with the internal cavity of the cavity 1. The external port of the connection port 6 is connected to the suction pump 7 through a connecting pipe. A valve switch 8 is installed on the connecting pipe;
[0023] Further, during the use process, the staff can use the cooperation of the two groups of leakage plates 3 through the pin holes and the pins 5 to install the current-limiting push plate 4 between the two groups of leakage plates 3, and then position and install the green ceramic substrate with pin holes above the topmost group of leakage plates 3 through the pins 5. The staff can pull the current-limiting push plate 4 to slide relative to the two groups of leakage plates 3 through the limiter 401. At the same time, the limiter 401 plays a limiting role to prevent the current-limiting push plate 4 from sliding out between the two groups of leakage plates 3;
[0024] Furthermore, in the process of pulling the current limiting push plate 4 to move, the current limiting opening 402 on the current limiting push plate 4 moves to an appropriate position accordingly, and cooperates with the leakage holes 301 on the two groups of leakage plates 3 and the number of hanging holes of different sizes on the raw ceramic substrate. The valve switch 8 is opened to start the suction pump 7, and a slurry flow channel is formed between the raw ceramic substrate, the leakage plate 3, the current limiting push plate 4, and the cavity 1, so that the excess hanging hole slurry on the raw ceramic substrate is sucked away, thereby achieving the effect of hole wall metallization. Therefore, without replacing the cavity 1 and the suction pump 7, the demand for suction flow of raw ceramic substrates of different sizes and different numbers of hanging holes can be reduced by pushing the current limiting push plate 4. This is suitable for the production of metallization of hole walls of raw ceramic substrates of different sizes and different numbers of hanging holes, thereby improving the practicability of the overall suction hole fixture, while ensuring product quality, improving efficiency, and reducing later production costs.
[0025] Working principle: During use, the staff can use the two groups of leak plates 3 to cooperate with the pin holes and the pins 5 to install the current limiting push plate 4 between the two groups of leak plates 3, and then use the pins 5 to position the raw ceramic substrate with the pin holes above the top group of leak plates 3. The staff can pull the current limiting push plate 4 to slide relative to the two groups of leak plates 3 through the limiter 401, and the current limiting opening 402 on the current limiting push plate 4 moves to the appropriate position accordingly, and cooperates with the leak holes 301 on the two groups of leak plates 3 and the number of hanging holes of different sizes on the raw ceramic substrate. Turn on the valve switch 8 to start the suction pump 7, and a slurry flow channel is formed between the raw ceramic substrate, the leak plate 3, the current limiting push plate 4, and the cavity 1. The excess hanging hole slurry on the raw ceramic substrate is sucked away, thereby achieving the effect of hole wall metallization. By pushing the current limiting push plate 4, the demand for suction flow of raw ceramic substrates of different sizes and different numbers of hanging holes is reduced, which is suitable for the production of hole wall metallization of raw ceramic substrates of different sizes and different numbers of hanging holes.
[0026] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
