Description

Technical Field

[0001] This utility model belongs to the field of sheet pressing technology, specifically relating to an LED sheet pressing device. Background Technology

[0002] LED wafers require multiple layers of materials to be bonded together during the production process. The production of these LED wafers requires the use of a vacuum press. The vacuum press heats and evacuates the material to press it together in order to process the LED wafers.

[0003] However, the current vacuum pressing machine has too large an internal space, which causes the vacuum pressing machine to take too long to create a vacuum during the vacuuming process. This results in an excessively long production time for LED wafers. Furthermore, during the pressing process of the aforementioned vacuum pressing machine, the wafers placed on the lower platen are not fixed and may shift during pressing, resulting in loose LED wafers, uneven molding pressure, and manufacturing defects such as air bubbles. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides an LED wafer pressing device. The LED wafer is placed on a pressing plate, and a pressing cover plate is clamped to the pressing base by a hydraulic telescopic rod. A heating plate heats the pressing plate, and a vacuum pump, through a vacuum pipeline and vacuum extraction port, evacuates air to adhere the wafer to the pressing plate, preventing displacement. Simultaneous heating and evacuation achieve vacuum heating and pressing of the LED wafer, resulting in even pressure application, better sealing, and prevention of loosening and air bubbles during wafer pressing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an LED wafer pressing device, including a machine housing, a protective frame covering the machine housing, a control unit installed inside the machine housing, and an input keyboard for operating the control unit located at the top of the machine housing via a keyboard drawer; a pressing mechanism is installed on the top of the machine housing, the pressing mechanism including a pressing base and a pressing cover plate rotatably connected to each other via a retaining spring shaft, a vacuum chamber inside the pressing base, a vacuum pump connected to the vacuum chamber via a vacuum pipeline installed on one side of the machine housing; and a cooling fan is installed on one side of the machine housing.

[0006] As a preferred embodiment, the pressing base is provided with hydraulic telescopic rods on both sides via rotating seats, and the upper ends of the hydraulic telescopic rods are connected to both sides of the pressing cover plate via rotating seats; a pressing plate is installed on the pressing base, and a pressing template is provided on the pressing plate; a heating plate is installed around the inside of the vacuum chamber.

[0007] As a preferred embodiment, the bottom of the vacuum chamber is connected to the vacuum pipeline through a vacuum extraction hole, and a handle is provided on the front end of the pressing cover plate; the pressing cover plate flips on the pressing base through a snap ring shaft and is sealed and pressed with the pressing base.

[0008] As a preferred embodiment, a three-color alarm light is installed on the top of the protective frame.

[0009] As a preferred embodiment, the bottom of the equipment chassis is equipped with casters with brakes.

[0010] As a preferred embodiment, the equipment chassis is equipped with a control switch panel for controlling the start and stop of the vacuum pump and heating plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention places LED wafers on a pressing template on a pressing plate, and presses a pressing cover plate and a pressing base together. A hydraulic telescopic rod maintains the pressure between the two. A heating plate heats the pressing plate, and a vacuum pump creates negative pressure in the vacuum chamber through a vacuum extraction pipeline. Air is then extracted through vacuum extraction holes on the pressing plate to firmly adhere the multi-layered wafers to the pressing plate, preventing displacement and shaping the soft LED wafers. This achieves vacuum heating and pressing of the LED wafers. The pressing cover plate and pressing base apply force while heating and evacuating simultaneously, resulting in even pressure distribution and better adhesion of the processed material. This prevents loosening and air bubbles during pressing and improves the pressing efficiency of the LED wafers. Attached Figure Description
