Problems solved by technology

However, the shortcoming of this device is that the heat-pressing platform is made of tempered glass material with good heat-resistant effect. Although a flat heat-pressing platform can be provided for semi-finished products during the heat-pressing process, the heat-gathering effect of the heat-pressing platform is not good. Good, even has the effect of heat dissipation, the heat supply heat is not enough and the second conductive adhesive 18 cannot smoothly enter the circuit on the die 11 from the hole on the spacer, resulting in poor contact between the upper part 13 and the circuit on the die 11, Even the phenomenon of open circuit reduces the pass rate of the keyboard circuit and wastes the manpower and material resources required for production.

Embodiment 1

[0053] Such as figure 2 as well as image 3 As shown, this embodiment proposes a hot pressing station for keyboard production, including: a hot pressing platform 1, on which a heat collecting groove is opened, and a heat collecting bearing sheet 2 is arranged in the heat collecting groove. The surface of the heat-bearing sheet 2 and the surface of the hot pressing platform 1 are on the same plane. The hot pressing platform 1 is provided with positioning posts through which the positioning holes of the semi-finished products pass. After the semi-finished products are placed on the hot pressing platform 1, the second conductive adhesive is uniform. Located directly above the heat gathering carrier sheet 2;

[0054] Such as Figure 4 As shown, specifically, the heat gathering bearing sheet 2 includes:

[0055] The thermal conductive cloth layer 21 is made of thermal conductive cloth material; and

[0056] The shaping layer 22 is adhered below the thermally conductive cloth layer 21 an...

Embodiment 2

[0062] The difference between this embodiment and embodiment 1 is that in order to keep the temperature of air everywhere in the supply cavity 321 consistent, the rotating tube is set to have an L-shaped structure to prevent the gas from directly rushing into a certain heat conduction hole 322 after air intake and cause air out of each heat conduction hole 322 At the same time, the rotating tube is set to rotate during jetting, so that the air in the supply chamber 321 is evenly mixed during the hot air jetting process.

[0063] Such as figure 2 , Figure 5 , Image 6 as well as Figure 7 As shown, the air receiving part 34 for connecting the air outlet pipe 51 is connected to the air receiving hole;

[0064] The air receiving part 34 includes:

[0065] The rotating tube 341 has an L-shaped structure. The rotating tube 341 passes through the air hole of the compression plate 32. The bent section of the rotating tube 341 extends into the supply chamber 321. The outlet tube 51 of the...

Embodiment 3

[0089] The difference between this embodiment and Embodiment 2 is only that: in order to avoid excessively high hot air derived from the heat conducting hole 322 causing deformation and damage of the semi-finished product, a temperature compensation system is added to this embodiment.

[0090] Such as figure 2 as well as Image 6 Specifically shown, the temperature compensation system includes:

[0091] The cold air supply system 71 has a cold air pipe 711 connected at its output end, and a cold air hole communicating with the cold air pipe 711 is provided on the compression plate 32 to provide cold air in the supply cavity 321;

[0092] The temperature sensor 72 is disposed at the heat conducting hole 322 of the pressing plate 32 to detect the temperature of the air flowing out from the heat conducting hole 322; and

[0093] The solenoid valve (not shown in the figure) is arranged on the cold air pipe 711, and the temperature sensor 72, the cold air supply system 71 and the solenoid ...

Abstract

The invention provides a hot-pressing station for keyboard production. The hot-pressing station comprises a hot-pressing platform, a heat collection groove is formed in the hot-pressing platform, a heat collection bearing piece is arranged in the heat collection groove, the surface of the heat collection bearing pieces and the surface of the hot-pressing platform are on the same plane, a positioning post for the positioning hole of a semi-finished product to pass through is arranged on the hot-pressing platform, and second conductive adhesive is located right above the heat collection bearing piece after the semi-finished product is placed on the hot-pressing platform; specifically, the heat collection bearing piece comprises a heat conductive layer made from heat conductive cloth materials and a sizing layer attached under the heat conductive cloth layer and made from heat resistance materials. The hot pressing station has the advantages that under the condition that the lower bearing of the semi-finished product is assuredly smooth during hot pressing, heat collection effect borne by the semi-finished product is improved.

Description

Technical field [0001] The invention relates to a hot pressing device, in particular to a hot pressing station for keyboard production. Background technique [0002] Such as figure 1 As shown, in the keyboard production process, after the die 11, the spacer 12, and the upper piece 13 (the die 11, the spacer 12, and the upper piece 13 are arranged in order from bottom to top), they need to be placed on the surface of the output part. Paste the reinforcing sheet, and paste the adhesive on the connection between the output part 16 and the body part 17 to obtain a semi-finished product, and then need to use a punch to punch holes on the semi-finished product to prevent the internal circuits from sticking together after the silver paste is overheated. Both sides of the main body 17 are provided with positioning holes 15. The die 11 and the upper pin 13 are both provided with circuits, and the die 11 is printed with the connection lines between the buttons. The upper pin 13 is mainly ...
