[0027] The heating and material transfer assembly 3 is composed of a heating platform 18, a feeding area 15, a Z1 lead screw, a Z1 motor, and an X1-axis lead screw and an X1 motor. A feeding area 15 is fixedly installed on one side of the heating platform 18, a Z1 motor and an X1 motor are arranged on the top of the workbench 1, and the output ends of the Z1 motor and the X1 motor are respectively fixedly connected to the Z1 lead screw and the X1-axis lead screw.

[0028] It should be noted that by installing a mechanical structure, a large LED chip can be fixed to the circuit board. Through different temperature zones, the temperature is raised and the chip is heated and fixed in a negative pressure space. The magazine 9 automatically loads and unloads materials, reducing labor costs and the rejection rate, thereby improving the product yield.

[0029] Specifically, when using this fully automatic eutectic furnace, an operator puts the LED chips into the magazine 9, starts the elevator motor 7, drives the screw to move up and down, and stops at each layer of the magazine 9 for feeding. The elevator stops accurately at each floor, and the elevator floor stop position can be set randomly. The operator puts the materials into the elevator through the magazine 9, reducing the generation of defects caused by direct contact with the product. Subsequently, the LED chips are moved to the feeding area 15, lifted up and down by the Z1 screw and the Z1 motor, and then moved left and right by the X1-axis screw and the X1 motor.

[0032] It should be noted that this fully automatic eutectic furnace simultaneously performs automatic feeding and discharging, without spending a large amount of time and effort to adjust the position of the LED chips, thereby improving the efficiency and quality of LED eutectic.

[0033] Specifically, this fully automatic eutectic furnace heats and moves the LED chips to the vacuum eutectic platform 13. Subsequently, the descending cylinder 17 is started to drive the sealing cover 12 to move downwards to cover the product and keep it in a sealed state. The vacuum pump is automatically turned on to pump air until the required negative pressure value is reached to achieve the eutectic effect of the product. After vacuum eutectic, the product is lifted up and down by the Z2 screw and the Z2 motor, and then moved left and right by the X2 screw to move the product to each cooling zone for cooling. After cooling, the product is pushed into the magazine 9 by the pushing cylinder 10 in the receiving platform. The elevator motor 7 drives the screw to move up and down, and stops at each layer of the magazine 9 for feeding. The elevator stops accurately at each floor, and the elevator floor stop position can be set randomly. The operator picks up the magazine 9 without direct contact with the product.

[0034] The working principle of the above embodiments is as follows:

[0035] (1) When using this fully automatic eutectic furnace, an operator manually places the LED chips into the material box 9, starts the elevator motor 7, which drives the screw rod to move up and down to make each layer of the material box 9 stay for feeding work. The elevator floor stop position is accurate, and the elevator floors can be set randomly. The operator reduces the chance of direct contact with the products by placing the materials in the material box 9 into the elevator. Subsequently, the LED chips are moved to the feeding area 15, and are lifted up and down by the Z1 screw rod and the Z1 motor, and then the products are moved left and right by the X1 axis screw rod and the X1 motor, and the same product is preheated eutectically in different temperature zones.

[0036] (2) For this fully automatic eutectic furnace, the LED chips are heated and moved to the vacuum eutectic platform 13. Subsequently, the descending cylinder 17 is started to drive the sealing cover (12) to move downwards to cover the product to maintain a sealed state. Then the vacuum pump is automatically turned on to pump air until the required negative pressure value is reached to achieve the eutectic effect of the product. After vacuum eutectic, the product is lifted up and down by the Z2 screw rod and the Z2 motor, and then moved left and right by the X2 screw rod to move the product to each cooling zone for cooling. After cooling, the product is pushed into the material box 9 by the pushing cylinder 10 in the receiving platform. The elevator motor 7 drives the screw rod to move up and down to make each layer of the material box 9 stay for feeding work. The elevator floor stop position is accurate, and the elevator floors can be set randomly. The operator picks up the material box 9 without direct contact with the products.
