Abstract
Description
Technical Field
[0001] This application relates to the field of semiconductor technology, and in particular to a film cutting device and a film applicator for a film applicator. Background Technology
[0002] Manual wafer laminators use manually controlled blades to rotate around a wafer at a fixed distance, circumferentially cutting the wafer film into a shape that fits the wafer's size. The wafer film protects either the front or back of the wafer, facilitating subsequent single-sided wafer processing without damaging the other side. However, manually controlling the blade rotation makes it difficult to precisely control the required rotation distance, which can easily lead to film flakes, particles, or debris that negatively impact subsequent processes.
[0003] Currently, the manual rotation distance is controlled by a brief audible prompt when the blade rotates one revolution, but in reality, the distance is still manually controlled, which cannot effectively prevent membrane filament formation. Summary of the Invention
[0004] This application provides a film cutting device for a film applicator, comprising:
[0005] A film cutting tool, comprising a film cutting blade and a first winding shaft fixedly connected to the film cutting blade;
[0006] A cutting control structure includes a cutting control line and a knot blocking part; the cutting control line can be wound around a first winding shaft and includes at least one or more continuous control line unit segments, each control line unit segment matching the circumference of the film-coated wafer, and each control line unit segment having a knot at its tail end; the knot blocking part has an outlet for the cutting control line to pass through, and the size of the outlet is smaller than the size of the knot; when the film-cutting blade makes one cut, the control line unit segment is wound around the first winding shaft once, and the knot of the control line unit segment is locked at the outlet.
[0007] In some embodiments, the cutting control structure has a control wire storage box, the control wire storage box having a housing forming a control wire storage cavity, the cutting control wire being stored in the control wire storage cavity, and a portion of the housing serving as a knot blocking portion.
[0008] In some embodiments, the housing has a bottom wall and a side wall, a portion of which serves as the knot blocking portion.
[0009] In some embodiments, the control line storage cavity is provided with a second winding shaft for winding the cutting control line.
[0010] In some embodiments, the cutting control structure further includes a control line processing tool, disposed at the outlet and located on the side where the knot is stuck, for processing the knot so that the cutting control line can continue to move out from the outlet;
[0011] The control line processing tool includes a knot cutter for cutting the control line at the knot; or, the control line processing tool includes a knot flattener for flattening the knot so that it can pass through the outlet.
[0012] In some embodiments, the cutting control structure further includes a support platform adapted to the control line processing tool for supporting the cutting control line when the control line processing tool processes the knot.
[0013] In some embodiments, the cutting control structure has a control wire storage box, the control wire storage box has a housing forming a control wire storage cavity, and the control wire processing tool includes a processing operation part located in the control wire storage cavity and a cutting button connected to the processing operation part and exposed outside the housing. When the cutting button is subjected to a pressing operation force, the processing operation part can cut the knot.
[0014] In some embodiments, the cutting control line is a metal wire.
[0015] In some embodiments, the film cutting tool further includes an operating handle connected to the film cutting blade for driving the film cutting blade and the first winding shaft to rotate;

[0018] The main technical effects achieved by the embodiments of this application are:
[0019] The film cutting device and film applicator provided in this application embodiment, by setting a first winding shaft fixedly connected to the film cutting blade on the film cutting blade, and setting a cutting control structure including a cutting control line and a knot blocking part, the tail end of each control line unit segment of the cutting control line has a knot, and the length of each control line unit segment of the cutting control line matches the circumference of the film-applying wafer, so that when the film cutting blade cuts around the outer perimeter of the wafer, the knot is just located at the outlet of the knot blocking part and is blocked by the outlet. In this way, by setting the length of the control line unit segment, it is possible to control the film cutting blade to stop rotating and cutting when it has just cut one circle, so as to more accurately control the film cutting operation of the film cutting blade and prevent the generation of film filaments due to the film cutting blade cutting too long.

The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.
[0024] The following is in conjunction with the appendix Figure 1 and Figure 2 The following describes some embodiments of this application in detail. Unless otherwise specified, the embodiments and features described below can be combined with each other.
[0025] Reference Figure 1 This application provides a film cutting device 100 for a film applicator. The film cutting device 100 for a film applicator includes a film cutting blade 10 and a cutting control structure 20.
[0026] The film cutting tool 10 has a film cutting blade 11 and a first winding shaft 12 fixedly connected to the film cutting blade 11.
[0027] The cutting control structure 20 includes a cutting control line 21 and a knot blocking part 22. The cutting control line 21 can be wound around the first winding shaft 12 and includes at least one or more continuous control line unit segments 210. Each control line unit segment 210 matches the circumference of the film-coated wafer 200. Each control line unit segment 210 has a knot 211 at its tail end. The knot blocking part 22 has an outlet 220 for the cutting control line 21 to pass through. The size of the outlet 220 is smaller than the size of the knot 211. When the cutting blade 11 makes one cut, the control line unit segment 210 is wound around the first winding shaft 12, and the knot 211 of the control line unit segment 210 is locked in the outlet 220.
[0028] The film cutting device 100 for the above-mentioned laminating machine has a first winding shaft 12 fixedly connected to the film cutting blade 11 on the film cutting blade 10, and a cutting control structure 20 including a cutting control line 21 and a knot blocking part 22. Each control line unit segment 210 of the cutting control line 21 has a knot 211 at its tail end, and the length of each control line unit segment 210 of the cutting control line 21 matches the circumference of the laminating wafer 200. When the film cutting blade 11 cuts around the outer perimeter of the wafer 200, the knot 211 is located at the outlet 220 of the knot blocking part 22 and is blocked by the outlet 220. By setting the length of the control line unit segment 210, the cutting blade 11 can be controlled to stop rotating and cutting when it has just cut one circle, so as to more accurately control the film cutting operation of the cutting blade 11 and prevent the generation of film filaments due to the cutting blade 11 cutting too long.
[0029] In some embodiments, the cutting control structure 20 has a control wire storage box 25, the control wire storage box 25 has a housing 250 forming a control wire storage cavity 201, the cutting control wire 21 is stored in the control wire storage cavity 201, and a portion of the housing 250 serves as the knot blocking portion 22.
[0030] In some embodiments, the housing 250 has a bottom wall 252 and a side wall 251, a portion of the side wall 251 serving as the knot blocking portion 22.
[0031] In some embodiments, the control line storage cavity 201 is provided with a second winding shaft 26 for winding the cutting control line 21, which facilitates the setting of multiple control line unit segments 210 and facilitates the continuous cutting of the film layers of multiple film-coated wafers 200.
[0032] In some embodiments, the cutting control structure 20 further includes a control line processing tool 23, which is located at the outlet 220 and on the side where the knot 211 is stuck, for processing the knot 211 so that the cutting control line 21 can continue to move out from the outlet and for cutting the knot 211.
[0033] In some embodiments, the control line processing tool 23 includes a knot cutter for cutting the control line 21 at the knot 211.
[0034] In this embodiment, when the cutting control line 21 at the knot 211 is cut, the knot 211 can also be cut off. The cutting control line 21 at the front end of the knot 211 can be removed from the outlet 220. Correspondingly, the subsequent cutting control line 21 can pass through the outlet 220, and its end is fixed to the first winding shaft 12. The end of the cutting control line can be fixed to the first winding shaft 12 by knotting or fixing structure.
[0035] In this embodiment, the cutting control line 21 includes multiple control line unit segments 210, and each control line unit segment 210 has the same length.
[0036] The length of each control line unit segment 210 can be determined based on the outer perimeter of the film-coated wafer 200, the distance from the control line storage box 25 to the first winding shaft 12, and the length of one turn of the cutting control line 21 wound on the winding shaft, so that when the cutting control line 21 is cut once by the film cutting blade 11, the knot 211 is just stuck at the outlet 220.
[0037] In other embodiments, the control line processing tool 23 includes a knot-pressing tool for flattening the knot 211 to allow it to pass through the outlet 220. In this embodiment, the knot 211 is flattened during processing, but the cutting control line 21 at the knot 211 is not cut. Accordingly, subsequent cutting control lines can pass through the outlet 220.
[0038] In this embodiment, the outlet 220 can be adapted to a shape that can block the flattened knot from passing through, but allows the flattened knot to pass through, such as the height of the outlet being less than the width of the outlet.
[0039] In this embodiment, the cutting control line 21 includes multiple control line unit segments 210. The first control line unit segment 210, which is initially fixed to and wound around the first winding shaft 12, is relatively long. The subsequent control line unit segments 210 are of equal length and shorter than the first control line unit segment 210.
[0040] The length of the first control line unit segment 210 can be determined based on the outer perimeter of the film-coated wafer 200, the distance from the control line storage box 25 to the first winding shaft 12, and the length of one turn of the cutting control line 21 wound on the winding shaft, so that when the first control line unit segment 210 is cut once with the film cutting blade 11, the knot 211 is just stuck at the exit 220. The lengths of the other control line unit segments 210 subsequently connected to the first control line unit segment 210 are determined based on the outer perimeter of the film-coated wafer 200 and the length of one turn of the cutting control line 21 wound on the winding shaft.
[0041] In some embodiments, the cutting control structure 20 further includes a support platform 27 adapted to the control line processing tool 23 for supporting the cutting control line 21 when the control line processing tool 23 processes the knot 211.
[0042] The support platform 27 is positioned opposite to the control line processing tool 23. For example... Figure 1 As shown, the support platform 27 is located below the control line processing tool 23.
[0043] In some embodiments, the cutting control structure 20 includes a control wire storage box 25, which has a housing 250 forming a control wire storage cavity 201. The control wire processing cutter 23 includes a processing operation unit 231 located within the control wire storage cavity 201 and a cutting button 232 connected to the processing operation unit 231 and exposed outside the housing 250. When the cutting button 232 is pressed, the processing operation unit 231 can cut the knot 211. The cutting button 232 can be connected to the processing operation unit 231 via a connecting part 233.
[0044] In some embodiments, the control line storage box 25 is provided with a mounting and fixing structure 24 for fixing the control line processing tool 23 to the control line storage box 25. For example... Figure 1 As shown, the mounting and fixing structure 24 can fix the control line processing tool 23 to the housing 250 of the control line storage box 25.
[0045] In some embodiments, the cutting control line 21 is a metal wire with a knot 211.
[0046] The material of the knot 211 can be the same as the material of the other parts of the cut control line 21, and the cut control line 21 can be integrally formed.
[0047] In some embodiments, the film cutting tool 10 further includes an operating handle 13 connected to the film cutting blade 11 for driving the film cutting blade 11 and the first winding shaft 12 to rotate.
[0048] In some embodiments, the operating handle 13 is disposed on the first winding shaft 12.
[0049] In some embodiments, the operating handle 13 may be located on the side of the first winding shaft 12 away from the film cutting blade 11 for convenient operation.
[0050] like Figure 1 As shown, in some embodiments, the first winding shaft 12 includes a first rod 121, a second rod 122, and a third rod 123 connecting the first rod 121 and the second rod 122. The first rod 121 and the second rod 122 extend in the same direction. A cutting blade 11 is connected to the end of the first rod 121 opposite to the third rod 123. An operating handle 13 can be connected to the third rod 123 and extends toward the side opposite to the cutting blade 11.
[0051] In some embodiments, the operating handle 13 is rod-shaped. The extending direction of the operating handle 13 is the same as the extending direction of the first rod 121 and the second rod 122.
[0052] It should be noted that in some other embodiments, the cutting tool can also be configured with other structures, and the first winding shaft can also be configured with other structural forms, such as sheet-like or columnar.
[0053] This application also provides a laminating machine. The laminating machine includes a laminating head, an operating platform, a control device, and a film cutting device 100 for the laminating machine as described above. The laminating head can laminate wafers. The operating platform may include a vacuum adsorption platform to adsorb and fix the wafer during the lamination process. The control device can control the laminating operation of the laminating head and the adsorption operation of the vacuum adsorption platform.
