3. Tablet pressing: Place the vibrating screen mold with copper particles on the ceramic substrate and fix it, and then cover the copper particles on the ceramic substrate through the blanking machine. A steel needle matching the through hole on the vibrating screen mold, the steel needle passes through the through hole to push the copper particles out and cover the ceramic substrate;

4. Sintering: stack the ceramic substrate covered with copper particles in 3 to 5 layers of brackets, put them into a sintering box for sintering;

5. Cutting: cutting the sintered ceramic substrate to obtain a single finished product.

As a preference, the vibrating screen machine includes a motor base and two vibrating frames, and two vibrating screen molds can be placed in the vibrating frames.

As a preference, the blanking machine includes a base, a down-pressing cylinder and a down-pressing plate, through which the steel needle on the down-pressing plate is penetrated into the through hole, and the copper particles are pushed out and covered on the ceramic substrate.

As a preference, 16 to 54 concave mold groups matching the position and size of a single tile copper particle are arranged in the rectangular body, and the groove depth of each concave mold is 0.3mm.

The present invention is a current transduction type piece, through the control of the input current, it can complete high-precision temperature control, coupled with temperature detection and control methods, it is very simple to complete remote control, program control, and computer control, and it is convenient to form an automatic control system. The thermal inertia of the product is very small, and the cooling and heating time is very fast. In the case of good heat dissipation at the hot end and no load at the cold end, the maximum temperature difference can be reached in less than one minute after power on. The efficiency of a single pair of cooling elements of the product is very small, but if they are combined into a stack, and the same type of stacks are combined in series or parallel to form a refrigeration system, the efficiency can be made very high, so the cooling efficiency can reach several milliwatts to tens of thousands of watts. The temperature range of the product is large, and it can be completed from a positive temperature of 90°C to a negative temperature of 130°C.

The beneficial effects of the present invention are: by adopting the mould, a plurality of ceramic refrigerating plates can be coated with copper at the same time, and mechanized operation is used to save time and labor, and the quality is stable, reducing the number of workers and improving work efficiency.
