Description

Technical Field

[0001] The invention relates to the technical field of brazing equipment, in particular to a brazing equipment and a welding process for processing a semiconductor heating disk. Background Art

[0002] A semiconductor heating plate, also known as a semiconductor wafer heating plate, is a device specifically used for heat treatment of silicon wafers in the semiconductor manufacturing process. It is usually made of high-temperature corrosion-resistant materials, such as high-purity aluminum, high-silicon metal, and ceramic quartz glass, to ensure the purity and reliability of the wafer during heat treatment. It usually uses electric heating wires or heating cores as heating elements, and transfers heat through the bottom of the heating plate. During the processing and manufacturing of the semiconductor heating plate, the various components need to be welded.

[0003] The Chinese patent application with publication number CN118417661A proposes a welding method for an aluminum wafer heating plate. First, a customized sleeve for accommodating the aluminum wafer heating plate is prepared. The customized sleeve includes a T-shaped sleeve, a first cover plate and a second cover plate. The first cover plate and the second cover plate correspond to the small opening and the large opening of the T-shaped sleeve, respectively. Then, the assembled aluminum wafer heating plate is sealed in the customized sleeve. After welding, the customized sleeve as a whole is degassed, hot isostatically pressed, and removed in sequence to complete the welding of the aluminum wafer heating plate. Based on the customized sleeve, hot isostatic pressing welding is used to achieve the welding of aluminum wafer heating plates with irregular structures, which can ensure that the welding bonding rate between the upper and lower plates of the aluminum wafer heating plate is greater than 95%, and the welding strength is greater than 50MPa, thereby ensuring the performance of the aluminum wafer heating plate.

[0004] When the above device is welding, the welding is carried out by using a customized sleeve to be installed on the outside of the heating plate workpiece. Accordingly, additional steps such as sleeve application and sleeve removal are required, and the process is relatively cumbersome. Secondly, the customized sleeve also increases the welding cost. In view of the situation proposed in the above application that the high temperature conditions of hot isostatic pressing are prone to deformation when the customized sleeve is not used, the method of brazing can avoid such problems.

[0034] Another technical problem to be solved by the present invention is to provide a brazing device for use in a welding process for processing a semiconductor heating plate, comprising the following steps: Workpiece placement The part of the heating plate workpiece 3 to be welded is stacked and placed on the top of the placement table 2, and the top part is inserted through the connection frame 693, and then the second bidirectional threaded rod 698 is rotated to control the two second clamping plates 682 to clamp the part of the heating plate workpiece 3 inserted through the connection frame 693, and finally the fourth electric push rod 69 is slightly pulled downward, so that the second clamping plate 682 can press the heating plate workpiece 3 downward, thereby ensuring the stability of the heating plate workpiece 3; Welding adjustment During the welding process, the placement table 2 is controlled to rotate by controlling the movement of the moving plate 63. During the rotation of the placement table 2, the transmission relationship between the second gear 65, the third gear 694, the fourth gear 695 and the fifth gear 696 can achieve the effect of synchronous rotation of the connection frame 693 and the placement table 2, thereby ensuring that the second clamping plate 682 can stably clamp the heating plate workpiece 3 while the heating plate workpiece 3 rotates; Welding Process The tank 597 delivers the fuel required for welding to the welding gun body 591 through a pipeline, and during welding, the connecting plate 54 can be adjusted to swing on the inner side of the mounting seat 53 with the rotating shaft 55 as the axis to adjust the welding angle.

Based on this step and the effect of controlling the rotation of the placement table 2 mentioned above, effective welding can be performed on different positions of the heating plate workpiece 3, and the entire process does not require excessive human involvement.

[0035] In the actual operation process, firstly, the device is connected to the power supply. When working, the heating disk workpiece 3 to be welded is stacked and spliced ​​on the top of the placement table 2 in sequence. After placement, the fourth electric push rod 69 works to pull the extension plate, and the extension plate drives the control plate 68 to be raised and lowered, and the control plate 68 drives the connection frame 693 to move. After the connection frame 693 moves to the top of the heating disk workpiece 3 and is inserted into the connection frame 693, the second two-way threaded rod 698 is rotated, and the second two-way threaded rod 698 drives the two second threaded blocks 699 to move toward each other. The threaded block drives the push plate 681 to move, and the push plate 681 drives the second clamping plate 682 to move to the position where the heating disk workpiece 3 is inserted into the connection frame 693 and clamped. After clamping, repeat the above steps of the fourth electric push rod 69 to cause the connection frame 693 to move slightly downward. It can be seen from the above connection relationship that at this time, the clamping plate forms an effect of driving the top of the heating disk workpiece 3 to press downward, thereby improving the overall stability of the heating disk workpiece 3 after splicing. After being placed, the welding gun body 591 can perform welding operations after working. During this period, the first electric push rod 52 pushes the mounting seat 53 horizontally after working. It can be known from the above connection relationship that the distance between the welding gun body 591 and the heating plate workpiece 3 can be adjusted at this time. During specific welding, the first control rod 56 and the second control rod 57 can be rotated separately during the welding work to adjust the angle between the brazing material rod 59 and the welding gun body 591, so that one end of the brazing material rod 59 can be at an angle that is melted by the high temperature of the welding gun body 591. After adjustment, the first two-way threaded rod 586 is rotated, and the first two-way threaded rod 586 drives the first threaded block 587 to move, and the first threaded block 587 drives the first clamping plate 588 to move until the two second clamping plates 682 are respectively attached to the outer surfaces of the first control rod 56 and the second control rod 57. There is friction, which can ensure the stability of the first control rod 56 and the second control rod 57 after adjustment, and ensure the stability of the welding work; During the welding process, as the solder rod 59 is consumed, the first motor 596 drives the connected guide wheel 595 to rotate after it starts working, and the guide wheel 595 drives the solder rod 59 to move, so that the end of the solder rod 59 can always be at the welding end position of the welding gun body 591 during the movement. At the same time, the second motor 599 drives the threaded adjustment rod 598 to rotate after it starts working, and the threaded adjustment rod 598 drives the lifting block 51 to move up and down, and the lifting block 51 drives the first electric push rod 52 to move, and the first electric push rod 52 drives the mounting seat 53 to move. It can be seen from the above connection relationship that the solder rod 59 can be adjusted at this time. The welding height of the welding gun body 591 is adjusted, and the second electric push rod 583 can push and pull the strip plate 581 up and down after working. The second electric push rod 583 pushes and pulls the strip plate 581 up and down, and the strip plate 581 drives the first rack 584 to move, and the first rack 584 drives the first gear 585 to rotate, and the first gear 585 drives the rotating shaft 55 to rotate, and the rotating shaft 55 drives the mounting seat 53 to swing and flip around the rotating shaft as the axis. It can be seen from the above connection relationship that the purpose of adjusting the welding angle can be achieved in this way, and there is no need for excessive human participation in the entire welding process, which saves manpower; Finally, after the third electric push rod 64 works, it pushes and pulls the moving plate 63, and the moving plate 63 drives the second rack 66 to move. After the second rack 66 moves, it drives the second gear 65 to rotate, and the second gear 65 drives the placement table 2 to rotate, and the placement table 2 drives the heating plate workpiece 3 on the top to rotate. During this period, the second gear 65 also drives the third gear 694 to rotate, the third gear 694 drives the square rod 691 to rotate, the square rod 691 drives the sleeve 692 to rotate, the sleeve 692 drives the fourth gear 695 to rotate, the fourth gear 695 drives the fifth gear 696 to rotate, and the fifth gear 697 drives the fifth gear 698 to rotate. 96 drives the connecting frame 693 to rotate, and the connecting frame 693 drives the auxiliary frame 697 to rotate. It can be seen from the above connection relationship that at this time, the clamping plate and the heating disk workpiece 3 rotate synchronously, and the two are in a static state relative to each other. Accordingly, the heating disk workpiece 3 is controlled to rotate while ensuring its stability when placed, which effectively ensures the smooth progress of the welding work. The operation of controlling the rotation of the heating disk workpiece 3 is coordinated with the height and angle operation of the above welding gun body 591, so that different positions of the heating disk workpiece 3 can be properly and effectively welded, and the welding process is more flexible.
