Description

Technical Field

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

[0002] A semiconductor heating plate, also known as a semiconductor wafer heating plate, is a device specifically used in semiconductor manufacturing processes to perform heat treatment on silicon wafers. It is usually made of high-temperature corrosion-resistant materials, such as high-purity aluminum, high-silicon metal, and ceramic quartz glass, etc., to ensure the purity and reliability during the wafer heat treatment process. It usually uses heating wires or heating cores as heating elements and transfers heat through the bottom of the heating plate. During the processing and manufacturing of semiconductor heating plates, welding is required for each component.

[0003] Chinese Patent Application with Publication No. CN118417661A proposed a welding method for an aluminum wafer heating plate. First, prepare a customized sleeve for accommodating the aluminum wafer heating plate. The customized sleeve includes a T-shaped sleeve barrel, a first cover plate, and a second cover plate. The first cover plate and the second cover plate respectively correspond to the small opening and the large opening of the T-shaped sleeve barrel. Then, seal the assembled aluminum wafer heating plate into the customized sleeve, and perform degassing, hot isostatic pressing welding, and sleeve removal on the whole customized sleeve 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 the irregularly structured aluminum wafer heating plate, which can ensure that the welding bonding rate between the upper and lower plate bodies of the aluminum wafer heating plate is > 95%, and the welding strength is > 50 MPa, ensuring the service performance of the aluminum wafer heating plate.

[0004] When the above device performs welding, it welds by sleeving a customized sleeve outside the heating plate workpiece. Correspondingly, it needs to additionally go through steps such as sleeving and sleeve removal, and the process is relatively cumbersome. Secondly, the customized sleeve also increases the welding cost. In the case of not using a customized sleeve as proposed in the above application, the high-temperature conditions of hot isostatic pressing are prone to cause deformation. The welding method using brazing can well avoid such problems. However, existing brazing generally uses manual welding, which is relatively labor-consuming. Therefore, a brazing equipment and a welding process for semiconductor heating plate processing are proposed here to solve the above problems. Summary of the Invention

And during this period, the welding height can be adjusted by controlling the lifting of the lifting block, and the connecting plate can also be controlled to swing around the rotating shaft, so as to achieve the purpose of adjusting the welding angle, thereby realizing the purpose of flexible welding. Compared with hot isostatic pressing welding, the welding method will not cause the deformation of non-welded parts of the heating plate workpiece due to excessive temperature. Secondly, little manual participation is required during the welding process, which greatly saves the expenditure of labor costs.

[0058] Another technical problem to be solved by the present invention is to provide a brazing device applied to the welding process of semiconductor heating plate processing, including the following steps:

[0059] Workpiece placement

[0060] Stack the parts to be welded of the heating plate workpiece 3 on the top of the placement table 2, and insert its top through the adapter frame 693. Then rotate the second bidirectional threaded rod 698 to control the two second clamping plates 682 to clamp the part of the heating plate workpiece 3 passing through the adapter frame 693. Finally, after the fourth electric push rod 69 pulls down slightly, the effect that the second clamping plate 682 presses the heating plate workpiece 3 downward can be achieved, so as to ensure the stability of the heating plate workpiece 3;

[0061] Welding adjustment

[0062] During the welding process, control the rotation of the placement table 2 by controlling the movement of the moving plate 63. During the rotation of the placement table 2, due to the transmission relationship between the second gear 65, the third gear 694, the fourth gear 695 and the fifth gear 696, the effect that the adapter frame 693 rotates synchronously with the placement table 2 can be achieved. In this way, while the heating plate workpiece 3 is rotating, the second clamping plate 682 can still stably clamp it;

[0063] Welding processing

[0064] The tank 597 delivers the fuel required for welding to the welding gun body 591 through a pipeline, and during welding, the adjustable connecting plate 54 swings with the rotating shaft 55 as the axis inside the mounting seat 53 to adjust the welding angle, and the welding height can be adjusted by controlling the lifting block 51 to move up and down. Based on this step and the effect of controlling the rotation of the placement table 2 above, different positions of the heating plate workpiece 3 can be properly welded, and the whole process does not require excessive human involvement.

[0065] In the actual operation process, firstly, the device is powered on. 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 being placed, 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 make the connection frame 693 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;

[0066] After being placed, the welding gun body 591 can perform welding operation 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;

[0067] During the welding process, as the filler metal rod 59 is consumed, the first motor 596 drives the connected guide wheel 595 to rotate after working. This guide wheel 595 drives the filler metal rod 59 to move, so that the end of the filler metal rod 59 can always be in the welding end position of the welding torch body 591 during the movement. At the same time, the second motor 599 drives the threaded adjusting rod 598 to rotate after working. The threaded adjusting rod 598 drives the lifting block 51 to move up and down. The lifting block 51 drives the first electric push rod 52 to move. The first electric push rod 52 drives the mounting seat 53 to move. Then, through the above connection relationship, it can be known that at this time, the welding height of the welding torch body 591 can be adjusted.
