[0001] The invention relates to the field of eutectic, and in particular to a socket chip eutectic device. Background Art

[0002] At present, in the eutectic process of the chip and the tube socket, the material picking fingers of the existing eutectic machine need to be clamped for many times before the eutectic is finally completed, resulting in many deep scratches on the surface of the tube socket. The main reason is that the fingers and the positioning parts are in hard contact with the tube socket for many times, so the quality requirements cannot be met. In addition, the existing eutectic tables heat the eutectic through the heating seat. Since the heating seat is set below the eutectic table, the air flow above the eutectic table is fast, so the stability of the temperature above the eutectic table cannot be effectively controlled, affecting the eutectic effect. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a socket chip eutectic device, which can complete the eutectic by only one clamping of the TO socket positioning clamping, and solve the problem of multiple and deep scratches on the socket surface caused by multiple clamping in the prior art.

[0026] Combined with Figure 1 , 2 As shown in Figure 3, a tube socket chip eutectic device includes a base 1, a eutectic table 2 and a control system. A heating seat 3 is provided below the eutectic table 2. A heating rod is provided inside the heating seat 3 for heating the eutectic table 2, and then the tube socket, heat sink and chip are eutectically fused together. It also includes a nitrogen heating device 4, a TO tube socket positioning and clamping device 5 and a push rod positioning device; the TO tube socket positioning and clamping device 5 is provided in two groups and used alternately. When the first group of TO tube socket positioning and clamping devices 5 completes the tube socket eutectic, the first group of TO tube socket positioning and clamping devices 5 withdraws from the eutectic table, and an external suction nozzle takes away the tube socket after eutecticization, and a new tube socket without eutecticization is put in at the same time. At this time, the second group of TO tube socket positioning and clamping devices 5 sends the previously taken tube socket into the eutectic table for eutecticization. After the eutecticization is completed, the external suction nozzle takes away the tube socket after eutecticization, and a new tube socket without eutecticization is put in at the same time, so as to achieve alternating work and improve work efficiency.

[0027] like Figure 4As shown, the TO tube seat positioning and clamping device 5 includes a tube seat suction nozzle 12, a finger clamp 13, a guide rail slider 16, a cylinder 18 and a cylinder mounting seat 19. The finger clamp 13 is fixed on both sides of the guide rail slider 16, and horizontal movement is achieved through the cylinder 18 to locate the center position of the TO tube seat 39. The tube seat suction nozzle 12 is set in the middle of the finger clamp 13, fixed by the suction nozzle mounting seat 14, and connected to the air pipe joint 15, and connected to the external air pipe; the guide rail slider 16 is fixed by the upper mounting seat 20 and the lower mounting seat 23, so that the finger clamp 13 can be opened and closed with high precision and horizontally moved. A limit block 17 is also provided on one side of the guide rail slider 16 to limit the forward and backward movement of the guide rail slider. A spring assembly is provided on the rear side of the finger clamp 13, and the spring assembly includes a compression spring 21 and a spring mounting seat 22. The compression spring 21 is matched and sleeved with the hole set in the upper mounting seat 20, and plays a buffering role when the finger clamp 13 moves forward and backward.

[0028] During operation, the TO tube socket positioning and clamping device 5 places the TO tube socket 39 to be eutectic from the external material taking nozzle onto the tube socket suction nozzle 12, and clamps and positions it through the left and right two finger clamps 13. After the positioning is completed, the tube socket suction nozzle 12 vacuums and sucks the TO tube socket 39, and then sends the TO tube socket 39 to the eutectic table 2. At this time, the compression spring 21 plays a buffering role to prevent the tube socket suction nozzle 12 from damaging the TO tube socket 39 due to excessive force. After the TO tube socket 39 contacts the eutectic table 2, the finger clamps 13 are opened to both sides by the cylinder 18, and do not contact the TO tube socket 39, so as to prevent the finger clamps 13 from scratching the surface of the TO tube socket 39 when the push rod 33 moves. The tube socket suction nozzle 12 is always in a vacuum state during the eutectic process, and the vacuum state is achieved by connecting the suction nozzle mounting seat 8 and the air pipe joint 4 to the external air path. The finger clamps 13 are installed on the high-precision guide rail slider 16, and the high-precision opening and closing action is achieved by the cylinder 18.

[0029] Combined with Figure 1 , 5 As shown in Figure 6, the nitrogen heating device 4 is arranged on one side of the eutectic table 2, including a nitrogen heating component and a eutectic table cover 6. The nitrogen heating component includes a heating tube mounting seat 8, a heating tube 9, an air inlet copper tube 10 and an air outlet copper tube 11. The air outlet copper tube 11 extends into the eutectic table cover 6. The upper panel of the eutectic table cover 6 is a glass panel 7, which is convenient for observation and better ensures the stability of the product eutectic. The heating tube 9 includes a quartz glass tube 24, an upper end cover 25 and a lower end cover 26 to form a heating cavity. The quartz glass tube 24 is provided with an electric furnace wire 27 and a temperature sensor 40. The electric furnace wire 27 is connected to the upper joint 31 and the lower joint 32 of the electric furnace wire for power supply. The heating tube 9 is fixed by the upper and lower fixing plates 28 on the heating tube mounting seat 8. A nitrogen blowing block 29 is provided on the top of the heating tube mounting seat 8 to blow away the air on the eutectic table; a gas pipe connector 30 is provided on one side of the nitrogen blowing block 29.

[0030] During operation, the electric furnace wire 27 is powered on to generate heat, so that the nitrogen in the heating tube 9 is heated to 420°C. The quartz glass tube 24, the upper end cover 25 and the lower end cover 26 form a heating cavity, and a high temperature resistant sealant is applied at the connection. The heated nitrogen enters from the inlet copper tube 10 provided on the lower end cover 26, and then comes out from the outlet copper tube 11 provided on the upper end cover 25, and is blown into the eutectic table cover 6 through the outlet copper tube 11, so that the temperature above the eutectic table 2 is kept stable.

[0031] like Figure 7 As shown, the push rod positioning device includes a push rod 33, a push rod mounting seat 34, a push rod cylinder 35, a cylinder mounting seat 36 and a connector 37 for connecting the push rod and the cylinder. The push rod positioning device also includes a push rod limit block 38 to limit the lowest position of the push rod 33 sliding up and down.

[0032] During operation, the push rod cylinder 35 pushes the cylinder push rod connecting block 38 and the push rod mounting seat 36, driving the push rod 33 to press the TO tube seat 39 upward, thereby realizing the positioning of the TO tube seat 39 in the vertical direction.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
