Description

Technical Field

[0001] The invention relates to a cutting blade replacement method and a cutting device, and in particular to a cutting blade replacement method and a cutting device for cutting a sheet wafer in the process of electronic components. Background Art

[0002] In the process of general electronic components, there is often a need to cut the workpiece into multiple chips to facilitate subsequent processing into electronic components. Taking the process of passive components as an example, Patent No. I627042 "Chip Cutting Device" has disclosed a cutting device that can cut the workpiece such as a sheet chip of a ceramic substrate into strip chips. The workpiece is placed on a carrier, and the carrier can be horizontally displaced relative to a frame. When the carrier is displaced to the bottom of the frame, a feeding device on the frame will drive a cutting device to move up and down to cut the workpiece on the carrier. The cutting device is provided with a main body and a fixed seat, and the fixed seat can pivot relative to the main body so that a cutter is selectively clamped between the main body and the fixed seat.

[0003] The prior art disclosed in the patent case No. 1627042 "Wafer Cutting Device" is that the cutting device of the cutting equipment mainly uses a plurality of screws to pass through the body and the fixing seat, so that the fixing seat is fixed on the body to keep the cutter clamped by the two. When the operator needs to replace the cutter, the operator needs to manually unscrew the plurality of screws one by one, and then manually separate the fixing seat from the body to remove the old cutter. After replacing the new cutter, the operator manually brings the fixing seat and the body closer together, and manually tightens the plurality of screws one by one, so that the fixing seat is fixed on the body so that the new cutter is clamped by the two. In addition to requiring many manpower-consuming and time-consuming operations, the prior art also requires the operator to lean over the carrier and reach out to the cutting device to apply force to replace the sharp cutter when replacing the cutter. Not only is the body prone to accidentally touching the mechanism, but the hands are also at risk of being cut by the cutter, which requires further research and improvement. Summary of the invention

Figure 3 The restoring force of the elastic element B131 pushes the second knife holder B12, so that the first clamping portion B112 is separated from the second clamping portion B121 to form a clamping gap B14, thereby releasing the old cutting knife E.

[0113] See also Figure 1 , 6 The knife placement mechanism D is provided on the base frame D1, and is provided with a first knife placement seat D2 which is located relatively close to the carrier C and driven by a first driving member D21 to be able to move up and down, and a second knife placement seat D3 which is located relatively far from the carrier C and driven by a second driving member D31 to be able to move up and down; wherein,

The new cutter F is positioned and erected on the side of the second cutter support portion D32 toward the carrier C in a manner that the knife surface F3 is adsorbed by the third holding portion D34, and the knife tip F1 faces downward and corresponds to the top of the film layer D25 of the bottom seat D35. Since the surface of the third holding portion D34 slightly protrudes from the second supporting surface D33, a gap is maintained between the knife surface F3 of the new cutter F that is positioned and erected and the second supporting surface D33.

[0117] See also Figure 1 , 7 In the embodiment of the present invention, when the old cutter E is blunt and needs to be replaced, the cutter mechanism B1 of the cutting device is supported by the clamping mechanism B3 with the pressing block B332 against one side of the second cutter seat B12, so that the second cutter seat B12 moves relative to the first cutter seat B11 and the old cutter E is clamped by the first clamping part B112 and the second clamping part B121; when replacing, the operator can place the new cutter F on the second cutter seat D3.

[0118] See also Figure 1 , 38, and then the knife placement mechanism D is made to move linearly in the X-axis direction along with the carrier C on the slide rail A3, so that the first knife placement seat D2 is moved to the first knife support portion D22 corresponding to the bottom of the old cutter E of the cutter mechanism B1, and the output rod B321 of the clamping mechanism B3 is retracted so that the first connecting member B341 is linked to be approximately horizontal in the X-axis direction, and the abutting member B33 is linked to be approximately vertical in the Z-axis direction so that the pressing block B332 is separated from the abutment on one side of the second knife seat B12, and the restoring force of the elastic element B131 will push the second knife seat B12, so that the first clamping portion B112 is separated from the second clamping portion B121 to form the clamping gap B14 and release the old cutter E. At this time, the old cutter E is still clamped. Figure 3 The first holding portion B114 on the surface of the first clamping surface B113 of the first clamping portion B112 is held by negative pressure adsorption.

[0119] See also Figure 1 , 3 9, the first knife holder D2 is driven to make the first knife support portion D22 rise and enter the gap B14 formed by the separation of the first clamping portion B112 and the second clamping portion B121 of the cutter mechanism B1, until the second holding portion D24 corresponds to the blade surface E3 of the old cutter E. At this time, the second holding portion D24 will start to negatively absorb and hold the old cutter E. Figure 3 The old cutter E is adsorbed and held by the first holding portion B114 of the first clamping portion B112, and the negative pressure of the first holding portion B114 is also closed to allow the old cutter E to be switched to be adsorbed and held by the second holding portion D24.

[0120] See also Figure 1 , 3 10. After the old cutter E is transferred to the second holding portion D24 for adsorption and holding, the first cutter holder D2 is driven to make the first knife support portion D22 descend to carry the old cutter E out of the slit B14 of the cutter mechanism B1.

[0121] See also Figure 1 , 3 , 11, and then the knife placement mechanism D is moved linearly along the X-axis on the slide rail A3 with the carrier C, so that the second knife placement seat D3 is moved to the lower side of the clamping gap B14 corresponding to the cutting knife mechanism B1, and the second knife placement seat D3 is driven to make the second knife support portion D32 carry the new cutting knife F to rise into the clamping gap B14 until the third holding portion D34 is positioned in the preset position corresponding to the first clamping surface B113, at which time the back F2 of the new cutting knife F will be pressed against Figure 3The lower edge of the blocking portion B1111 of the blocking member B111 is moved, and the first holding portion B114 on the surface of the first clamping surface B113 of the cutter mechanism B1 will start to negatively pressure and adsorb and hold the new cutter F that was originally adsorbed and held by the third holding portion D34 of the second knife portion D32. At this time, the negative pressure of the third holding portion D34 will be closed to allow the new cutter F to be transferred to be adsorbed and held by the first holding portion B114, so that the new cutter F is completely installed in the cutter mechanism B1.

[0122] See also Figure 1 , 3 , 12, the new cutter F completes the conversion to Figure 3 After the first holding portion B114 is adsorbed and held, the second knife holder D3 is driven to descend so that the second knife support portion D32 moves out of the slit B14.

Figure 3 The cutting blade E is moved into the gap B14, and the cutting blade placement mechanism D moves linearly in the X-axis direction on the slide rail A3 along with the carrier C to return to the original position to complete the automatic replacement operation of the old cutting blade E and the new cutting blade F.

[0124] In the cutter replacement method and cutting device of the embodiment of the present invention, since the old cutter E is moved out of the cutter mechanism B1 and the new cutter F is installed in the cutter mechanism B1 by the cutter placement mechanism D, the operator can avoid the time-consuming operation of manually replacing the cutter, thereby increasing the efficiency of replacing the cutter and reducing the risk of the operator.
