Description

Intelligent high-precision temperature measurement hot pressing equipment for aluminum substrate production Technical Field The invention relates to the technical field of aluminum substrate processing, in particular to intelligent high-precision temperature measurement hot pressing equipment for aluminum substrate production. Background The aluminum substrate is a metal-based copper-clad plate with good heat dissipation function, and a single panel is generally composed of a three-layer structure, namely a circuit layer (copper foil), an insulating layer and a metal base layer. Is common in LED lighting products. The LED lamp is characterized in that the LED lamp is provided with a front side and a back side, the white side is welded with LED pins, the other side is aluminum, and the white side is generally contacted with the heat conducting part after heat conducting gel paste is smeared. But traditional aluminium base board hot pressing equipment simple structure, result of use is not good. The utility model discloses a hot pressing box for aluminum substrate production, which is characterized by comprising a box body, wherein a filter cavity and a mounting cavity are arranged in the box body, a mounting frame is fixed on the inner side of the mounting cavity, a cylinder is arranged on the surface of the mounting frame, a connecting block is fixedly connected with the lower end of the cylinder, a pressing plate is arranged at the lower end of the connecting block, and a heating block and a temperature sensor are arranged on the surface of the pressing plate. The hot pressing box directly heats the pressing plate through the heating block and is electrically connected with the temperature controller through the temperature sensor, compared with the traditional method that the heating device is used for heating heat conduction oil in advance, the structure is simple, the heating efficiency is effectively improved when the heat conduction oil flows into the pressing plate inside the pressing plate, the hot pressing box pushes the bottom plate to push the sealing door to open through the electric telescopic rod, the aluminum substrate is replaced outside the box, compared with the existing method that the box door is opened, the hand stretches into the box to replace the aluminum substrate, and the high-temperature baking of the hand and the large opening and closing of the box door are reduced, and the internal heat leakage is greatly reduced. First, the hot pressing box for aluminum substrate production of the prior art solves the problem that hands extend into the box body to replace aluminum substrates to a certain extent, but the structural design is unreasonable, when the aluminum substrates are replaced outside the box, the hot pressing box is in a non-sealing state, and meanwhile, the aluminum substrates need to be replaced for a sufficient time, so that time and labor are wasted, the temperature in the hot pressing box is lost, the temperature of a pressing plate is further influenced, the follow-up pressing quality is reduced, and the follow-up continuous aluminum substrate pressing industry is not facilitated. Secondly, the hot pressing box for aluminum substrate production in the prior art has poor use effect, specifically, the temperature control of the pressing plate is not accurate enough, and further analysis is carried out, and the pressing plate temperature sensor in the prior art is controlled by a temperature controller, so that the hot pressing box is only schematically illustrated and not intelligent enough. In the hot pressing production and processing process of the aluminum substrate, different and more accurate temperature requirements may be required for aluminum substrate series products with different specifications, and the temperature controller mentioned in the prior art cannot realize diversified temperature sampling, screening and algorithm recognition of the limit value temperature of the pressing plate, so that intelligent and reasonable temperature regulation feedback command operation cannot be performed on the pressing plate. Thirdly, the design of the platen driving structure of the hot pressing box for aluminum substrate production in the prior art is unreasonable, specifically, the prior art only adopts a single air cylinder to operate, and the driving speed and the driving pressure of the air cylinder are not required and specified, and the pressing speed and the pressing force of different degrees are required in the hot pressing process for aluminum substrates with different thicknesses. Meanwhile, the lamination of the aluminum substrates in the production and processing process is more required to meet the pressure requirements of layering and step-by-step loading, and the production quality of the aluminum substrate hot pressing can be improved, so that intelligent high-precision temperature measurement hot pressing equipment for aluminum substrate production i
