DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] This embodiment discloses a multi-wire cutting machine processing system, referring to Figure 1-Figure 7 The multi-wire saw 900 is described in detail, and includes a tooling mechanism 100. The tooling mechanism 100 is mounted on a worktable 6 of the multi-wire saw 900, and a workpiece 1 to be cut is mounted on the tooling mechanism 100. The cutting wire 9 in the multi-wire saw 90 is wound around a guide roller 91 to form a plurality of parallel and equidistantly distributed cutting segments 901, which can cut the workpiece 1 into a plurality of wafers 11.

[0034] Reference Figure 3-Figure 6 As shown, the tooling mechanism 100 plays the role of installing the workpiece 1. The tooling mechanism 100 includes a tooling base plate 5, a tooling base 4, a fillet layer 3 and an auxiliary material layer 2. The tooling base plate 5, the tooling base 4, the fillet layer 3 and the auxiliary material layer 2 are arranged from bottom to top.

[0035] The tooling base 4 is fixedly mounted on the upper side of the tooling base plate 5, and the tooling base 4 and the tooling base plate 5 are fixedly connected to form a single structure. The tooling base 5 is located on the lower side, connecting to the worktable 6 of the multi-wire saw 900; the tooling base 4 is located on the upper side, connecting to the workpiece 1 and other components above.

[0036] A fillet layer 3 is installed on the upper side of the tooling base 4. This layer 3 is divided into multiple sections, specifically several fillet strips 31. Each fillet strip 31 is of uniform shape and size, roughly forming a long rectangular parallelepiped structure. Each fillet strip 31 is arranged parallel and equidistantly. After the fillet strips 31 are installed, gaps 32 are formed between adjacent fillet strips 31. The positions of the gaps 32 correspond to the cutting positions of the cutting lines 9. The width of the gaps 32 is greater than that of the cutting lines 9, allowing them to accommodate the cutting lines 9.

[0037] Auxiliary material layer 2 is mounted on top of fillet layer 3, and the upper side of auxiliary material layer 2 is used to mount workpiece 1. Auxiliary material layer 2 is bonded to the upper workpiece 1 and the lower fillet layer 3, respectively, to secure workpiece 1. For example, auxiliary material layer 2 can be made of a single piece of polymer resin and bonded to workpiece 1 and fillet layer 3 by adhesive bonding.

[0038] Reference Figure 1 、 Figure 2 As shown, in this embodiment, the multi-wire cutting machine processing system further includes a multi-wire cutting machine 900, and the multi-wire cutting machine 900 includes a cutting wire 9, which is supported by a drive system and multiple rollers and can achieve continuous operation;

[0039] In the working position, the multi-wire saw 900 is equipped with two guide rollers 91. The cutting wire 9 is supported and guided by the guide rollers 91. It passes through the two guide rollers 91 to form a number of parallel and equidistant cutting segments 901. The cutting segments 901 can cut the workpiece 1. The cutting segments 901 are arranged in parallel and equidistant from each other. The distance between adjacent cutting segments 901 is roughly the thickness of the wafer 11 after the workpiece 1 is cut.

[0040] The multi-wire cutting machine 900 has a lifting platform 7 that can be adjusted up and down. A workbench 6 is installed on the upper side of the lifting platform 7, and a tooling mechanism 100 is installed on the upper side of the workbench 6. The cutting section 901 of the cutting wire 9 is located directly above the tooling mechanism 100 and can cut the workpiece 1.

[0041] During the cutting process, the driver drives the roller to rotate, driving the cutting line 9, and the lifting platform 7 moves upward. The upper side of the workpiece 1 first contacts the cutting line 9 for cutting, until the cutting line 9 completely cuts the workpiece 1, and the cutting line 9 will leave the lower side of the workpiece 1; the lifting platform 7 continues to rise, and the cutting line 9 will continue to cut the auxiliary material layer 2 until the auxiliary material layer 2 is completely cut, and the cutting line 9 will be embedded in the gap groove 32 between adjacent fillets 31, and the cutting line 9 will be temporarily stored through the gap groove 32; the multi-wire cutting machine 900 suspends operation, removes the cut workpiece 1 and the tooling mechanism 100, and then lowers the lifting platform 7 to move the cutting line 9 out of the gap groove 32 between adjacent fillets 31, waiting for the next cutting.

[0042] Reference Figure 5 、 Figure 6 As shown, the upper side of the tooling base 4 is provided with a plurality of mounting slots 41. The width of the mounting slots 41 matches the fillet 31, and the number of mounting slots 41 corresponds to the number of fillet 31. During installation, the fillet 31 has its lower portion embedded in the mounting slot 41, while its upper portion protrudes from the mounting slot 41. The upper side surfaces of the fillet 31 are coplanar, providing smooth support for the auxiliary material layer 2 and the workpiece 1.

[0043] The appropriate tooling mechanism 100 is selected based on the thickness of the wafer 11 being cut from the workpiece 1, and the width and spacing of the fillet 31 are specifically set. For example, in this embodiment, the thickness of the wafer 11 to be cut from the workpiece 1 is 3 mm, and a 0.20 mm diameter cutting line 9 is selected for cutting. The width of the fillet 31 is 2 mm (±0.01 mm), approximately 1.99 mm to 2.01 mm. The width of the mounting groove 41 is also adapted to the desired thickness, and the edges of the fillet 31 are chamfered to facilitate insertion and installation. The mounting groove 41 on the upper side of the tooling base 4 is 5 mm deep, and the spacing between adjacent mounting grooves 41 is 1.2 mm (+0.05 / -0 mm), approximately 1.20 mm to 1.25 mm. When installed, the molding 31 can be smoothly embedded in the installation groove 41, with approximately 1 / 3 of the molding 31 embedded in the installation groove 41, and approximately 2 / 3 of the upper side of the molding 31 exposed on the upper side of the tooling base 4 to form a gap groove 32 for accommodating the cutting line.

[0044] Reference Figure 5-Figure 7 As shown, the tooling mechanism 100 further includes a fixing assembly 8, through which the molding 31 can be fixed to the tooling base 4. The fixing assembly 8 is an annular structure, which is sleeved on the outer periphery of the tooling base 4 and can press and fix the molding 31 installed on the tooling base 4.

[0045] The fixing assembly 8 includes a connecting enclosure 81, a movable enclosure 83, and two fixed enclosures 82. The connecting enclosure 81 and the movable enclosure 83 are arranged opposite each other, and the two fixed enclosures 82 are arranged opposite each other. The four enclosures surround the four edges of the outer periphery of the tooling base 4. The ends of the fixed enclosure 82 are fixedly connected to the connecting enclosure 81 and the movable enclosure 83 respectively, and the connection points can be fixed with bolts.

[0046] Reference Figure 5As shown, both ends of the mounting groove 41 are continuous, and the length of the molding 31 is greater than that of the mounting groove 41, so that when the molding 31 is installed, the ends of the molding 31 extend from the ends of the mounting groove 41. Two fixed enclosures 82 are located at the two ends of the mounting groove 41. On the side of the fixed enclosure 82 facing the mounting groove 41, there are limit grooves 822 corresponding to the molding 31. The two ends of the molding 31 are respectively inserted into the limit grooves 822 of the two fixed enclosures 82. After the molding 31 is inserted into the limit grooves 822, the ends of the molding 31 can abut against the inner walls of the limit grooves 822, applying pressure to the ends of the molding 31. When the fixing assembly 8 is installed, the molding 31 can be compressed and fixed.

[0047] To improve the installation stability of the fixed enclosure 82, a horizontal positioning ridge 821 is integrally connected to the lower side of the fixed enclosure 82. A positioning groove 3 42 is provided on the outer side of the tooling base 4. The positioning ridge 821 fits into the positioning groove 3 42, achieving horizontal locking and limiting, thereby improving the positioning accuracy of the fixed enclosure 82.

[0048] Reference Figure 7 As shown, the movable enclosure 83 includes a connecting piece 1 831 and a connecting piece 2 832. The movable enclosure 83 is composed of two parts, the connecting piece 1 831 and the connecting piece 2 832, forming a detachable structure, which can easily realize the disassembly and assembly of the fixed assembly 8. Specifically, the ends of the connecting piece 1 831 and the connecting piece 2 832 that are separated from each other are fixedly connected to the fixed enclosure 82 on both sides, and the ends of the connecting piece 1 831 and the connecting piece 2 832 that are close to each other are detachably connected by a quick-release joint, which can realize two types of disassembly and assembly. Specifically, the quick-release joint includes a joint 1 834 and a joint 2 835. The joint 1 834 is installed at the end of the connecting piece 1 831, and the joint 2 835 is installed at the end of the connecting piece 2 832. The joint 1 834 and the joint 2 835 can be fixed by a snap connection, and can also be easily disassembled and assembled, thereby realizing the disassembly and assembly of the fixed assembly 8.

[0049] An arc-shaped elastic portion 1 811 is formed in the middle section of the connecting enclosure 81, and an arc-shaped elastic portion 2 833 is formed in the connecting piece 1 831. By bending the middle section into an arc, the arc-shaped structure can form a certain elastic expansion space, which is convenient for fine-tuning. Moreover, after the fixing component 8 is locked and fixed, the elasticity formed by stretching the arc-shaped segment can form a locking force, which can maintain the pressing force of the fixing component 8 on the end of the molding 31, thereby maintaining the installation stability of the molding 31.

[0050] Reference Figure 3-Figure 7As shown, the tooling base plate 5 is a detachable structure that is snap-fitted onto the workbench 6. A positioning baffle 61 is fixedly attached to one periphery of the workbench 6, and spring clips 62 are attached to the other three peripheries. The upper edge of the positioning baffle 61 protrudes from the upper side of the workbench 6, and a second positioning protrusion 611 is integrally fixedly attached to the side of the positioning baffle 6 facing the center of the workbench 6. The upper side of the spring clip 62 protrudes from the upper side of the workbench 6, and a first positioning protrusion 621 is integrally formed on the side facing the center of the workbench 6.

[0051] The tooling base plate 5 is mounted on the upper side of the workbench 6, with one edge of the tooling base plate 5 abutting against the positioning stop plate 61 to achieve a pressure-limited position. A second positioning groove 52 is defined on the side of the tooling base plate 5 facing the positioning stop plate 61. The second positioning groove 52 and the second positioning protrusion 611 form a mutually compatible hemispherical structure, and the second positioning protrusion 611 is inserted into the second positioning groove 52 to achieve a snap-fit ​​position.

[0052] The tooling base 5 has three side edges facing the spring clip 62, each with a first positioning groove 51. The second positioning groove 52 is a semi-cylindrical depression; correspondingly, the first positioning protrusion 621 matches the shape of the first positioning groove 51, also forming a semi-circular protrusion. The first positioning protrusion 621 of the spring clip 62 and the first positioning groove 51 can be interlocked and fixed.

[0053] When installing the tooling base 5, first directly engage one side of the tooling base 5 with the positioning stopper 61, and then press the tooling base 5 downward to engage the tooling base 5 between the spring clips 62 to complete the installation of the tooling base 5. When removing the tooling base 5, pull the tooling base 5 upward, and the spring clips 62 will produce a certain elastic deformation, allowing them to disengage from the positioning groove 1 51, thus completing the removal.

[0054] This embodiment also discloses a control method for a multi-wire cutting machine processing system. When using the multi-wire cutting machine processing system as described above, the workpiece 1 is mounted using the above-mentioned tooling mechanism 100, and the multi-wire cutting machine 900 is operated to cut the workpiece 1 into multiple chips 11 through the cutting segment 901 of the cutting wire 9.
