Description
Technical Field
[0001] The present application relates to the technical field of wire cutting machines, and in particular to a wire cutting machine. Background Art
[0002] The wire cutting machine is mainly composed of three parts: machine tool, CNC system and high-frequency power supply. The wire cutting machine can cut materials such as high-strength, high-toughness, high-hardness, high-brittleness, magnetic materials, as well as precise and small parts with complex shapes.
[0003] Wire cutting machines are currently the main equipment for processing materials such as silicon carbide, photovoltaic silicon rods, semiconductors, and sapphire. The wire cutting machine brings abrasive particles into the processing area of the crystal rod for grinding through the back-and-forth movement of the cutting wire net, thereby processing the crystal rod into several thin slices. The feed assembly of the wire cutting machine includes a feed mechanism and a swing mechanism. The feed mechanism is fixed to the main frame and is responsible for vertically feeding the crystal rod up and down. The swing mechanism is assembled to the lifting structure of the feed mechanism and moves up and down with the feed mechanism, while clamping and swinging the crystal holder.
[0004] At present, the swing mechanism of the wire cutting machine causes relative movement between the crystal rod and the feeding mechanism while clamping and swinging the crystal rod, which makes it difficult to achieve waterproof sealing. In addition, the clamping part of the swing mechanism generally uses a cylinder or a gas cylinder to drive the piston to lock the crystal holder, which increases the horizontal or vertical layout space of the clamping part, thereby increasing the manufacturing difficulty and manufacturing cost of the wire cutting machine.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.
[0025] It should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly indicate the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.
[0026] like Figure 1 As shown, a wire cutting machine 100 includes a frame 11, a feed device 12, a swing device 13 and a wafer support device 14. In order to clearly illustrate the technical solution of the present application, the following are also defined: Figure 1 The up-down, left-right, and front-back directions shown in the figure correspond to the vertical, width, and length directions described below. Figure 1 The up-down, left-right, and front-back directions of the center wire saw 100.
[0027] like Figure 2 As shown, the feed device 12 is fixed on the frame 11, and the feed device 12 includes a lifting mechanism 121. The feed device 12 moves relative to the frame 11 in the vertical direction through the lifting mechanism 121, so that the wire cutting machine 100 feeds the crystal rod 200 in the vertical direction.
[0028] The swing device 13 is connected to the lower part of the lifting mechanism 121 to move synchronously with the feed device 12, and clamps and swings the crystal support device 14. The swing device 13 includes a swing component 131 and a clamping component 132. The swing component 131 is connected to the lifting mechanism 121. The clamping component 132 is arranged below the swing component 131. At least part of the crystal support device 14 is arranged below the clamping component 132. The crystal support device 14 is used to fix the crystal rod 200. The swing device 13 clamps the crystal support device 14 through the clamping component 132, and drives the crystal rod 200 to swing through the swing component 131, so as to realize the swing-type cutting of the crystal rod 200 by the wire cutting machine 100.
[0029] like Figure 2 and Figure 3As shown, as an implementation, the swing assembly 131 includes a first fixed plate 1311 and an arc-shaped guide rail 1312, and the clamping assembly 132 includes a second fixed plate 1321. The first fixed plate 1311 is connected to the lower part of the lifting mechanism 121, and the arc-shaped guide rail 1312 is installed below the first fixed plate 1311, and the arc-shaped guide rail 1312 is slidably connected to the first fixed plate 1311, and the arc-shaped guide rail 1312 can slide relative to the first fixed plate 1311 along its own contour direction, and drive the crystal rod 200 to swing along the contour direction of the arc-shaped guide rail 1312. The arc-shaped guide rail 1312 is installed on the second fixed plate 1321 and the second fixed plate 1321 is located below the arc-shaped guide rail 1312, so that a swing chamber 1313 is formed between the first fixed plate 1311 and the second fixed plate 1321, and the arc-shaped guide rail 1312 is arranged in the swing chamber 1313.
[0030] Since the wire cutting machine 100 may generate tiny metal particles and debris when cutting the crystal rod 200, these metal particles may not be completely discharged under the flushing of the working fluid, causing these liquids, particles and debris to enter the swing chamber 1313, thereby affecting the operation of the swing device 13 and damaging the components in the swing chamber 1313.
[0031] In order to prevent liquid and debris from entering the swing chamber 1313, Figure 3 and Figure 5 As shown, the swing device 13 also includes a protective component 133 for waterproofing and sealing the swing component 131, and the protective component 133 includes a first protective cover 1331 and a second protective cover 1332. The first protective cover 1331 is installed inside the second protective cover 1332, so as to prevent liquid and debris from directly entering the swing chamber 1313 after the second protective cover 1332 is damaged. The first protective cover 1331 can further prevent liquid and debris from entering the swing chamber 1313, thereby improving the protective ability of the protective component 133 to the swing component 131.
[0032] like Figure 3 As shown, the first protective cover 1331 is disposed around the swing chamber 1313 to protect the components in the swing chamber 1313, such as the arc guide rail 1312. Exemplarily, the first protective cover 1331 can be a sheet metal cover, which has a high load-bearing capacity and corrosion resistance, and can improve its waterproof and debris-proof capabilities.
[0033] Specifically, the first protective cover 1331 is connected to the first fixing plate 1311 and the second fixing plate 1321 respectively by adhesion, surrounding and closing the swing chamber 1313. The above connection method is used to ensure the sealing of the swing chamber.
[0034] like Figure 5As shown, the second protective cover 1332 is disposed outside the first protective cover 1331 to provide double protection for the swing assembly 131. For example, the second protective cover 1332 may be an accordion protective cover, which has good flexibility, occupies little space, and can improve its ability to prevent collision deformation and improve its sealing effect.
[0035] In order to further improve the waterproof sealing effect of the swing assembly 131, as Figure 6 As shown, the swing device 13 also includes a humidity sensor 134, which is arranged in the swing chamber 1313 to sample the humidity in the swing chamber 1313. The wire cutting machine 100 is also equipped with a control system (not shown) connected to the humidity sensor 134. The humidity sensor 134 transmits a sampling signal representing the humidity in the swing chamber 1313 to the control system, and the control system performs corresponding display according to the sampling signal. Exemplarily, when the humidity is greater than or equal to the set threshold, the control system issues a prompt message to remind the operator to take timely measures.
[0036] As a way to achieve this, Figure 2 and Figure 3 As shown, the clamping assembly 132 includes a first clamping mechanism 1322 and a second clamping mechanism 1323, and the first clamping mechanism 1322 and the second clamping mechanism 1323 are both arranged below the second fixed plate 1321, and the first clamping mechanism 1322 and the second clamping mechanism 1323 are distributed on both sides of the crystal support device 14 along the width direction of the wire cutting machine 100, so as to achieve the clamping of the crystal support device 14 by the clamping assembly 132, thereby improving the accuracy of cutting the crystal rod.
[0037] Alternatively, if Figure 4 As shown, the first clamping mechanism 1322, the second clamping mechanism 1323, and the second fixing plate 1321 surround and form a receiving groove 1324 for accommodating the crystal support device 14. The width D1 above the receiving groove 1324 is greater than the width D2 below the receiving groove 1324. The receiving groove 1324 is shaped like a dovetail, so the clamping assembly 132 is more suitable for clamping the dovetail-shaped crystal support device 14.
[0038] The first clamping mechanism 1322 , the second clamping mechanism 1323 and the second fixing plate 1321 are preferably of split structure, that is, the first clamping mechanism 1322 and the second clamping mechanism 1323 are detachably mounted on the second fixing plate 1321 , which is easy to process and saves materials.
[0039] Furthermore, if Figure 3As shown, the first clamping mechanism 1322 includes a first clamping base 1322a and a first clamping bar 1322b. The first clamping bar 1322b is disposed on a side of the first clamping base 1322a facing the wafer support device 14 so that the clamping assembly 132 can accurately control the clamping and loosening of the wafer support device 14.
[0040] The first clamping strip 1322b has the freedom of movement relative to the second fixing plate 1321 in the width direction, and a movable gap extending in the width direction is provided between the first clamping base 1322a and the first clamping strip 1322b.
[0041] As an implementation method, the length of the active gap is greater than or equal to 0 and less than or equal to 2.4 mm. The first clamping mechanism 1322 can adjust the distance between the first clamping bar 1322b and the first clamping base 1322a within the above range to clamp or loosen the crystal support device 14. This setting allows the operator to change the clamping force by adjusting the active gap between the first clamping base 1322a and the first clamping bar 1322b. This setting enables the clamping assembly 132 to adapt to crystal support devices 14 of different sizes or shapes, thereby improving the applicability and flexibility of wire cutting.
[0042] like Figure 3 As shown, the second clamping mechanism 1323 is relatively fixed with the second fixed plate 1321 and the second clamping mechanism 1323 includes a second clamping base 1323a and a second clamping strip 1323b. The second clamping strip 1323b is fixedly mounted on the other side of the second clamping base 1323a toward the crystal support device 14 to ensure that when the first clamping mechanism 1322 clamps or releases the crystal support device 14, the second clamping base 1323a and the second clamping strip 1323b can provide fixed support and buffering effect to the crystal support device 14, thereby improving the stability of the clamping assembly 132.
[0043] In the example of the present application, the first clamping strip 1322 b and the second clamping strip 1323 b are both made of rubber material to reduce the wear of the crystal support device 14 and the first clamping mechanism 1322 and the second clamping mechanism 1323 .
[0044] Preferably, if Figure 3 As shown, the first clamping mechanism 1322 further includes a fastener 1322c, which is inserted through the first clamping base 1322a and abuts against the first clamping strip 1322b. The fastener 1322c is manipulated to drive the first clamping strip 1322b to move toward the crystal support device 14 until the first clamping strip 1322b abuts against the crystal support device 14, thereby clamping the crystal support device 14. The fastener 1322c is manipulated to drive the first clamping strip 1322b to move away from the crystal support device 14, thereby releasing the crystal support device 14.
[0045] As a way to achieve this, Figure 6 As shown, the swing assembly 131 also includes a pulley 1314, which is installed above the second fixed plate 1321 and located in the swing chamber 1313. Two arc-shaped guide rails 1312 are provided and distributed along the length direction of the wire cutting machine 100. The double arc-shaped guide rails 1312 can provide good guiding stability to achieve smooth and accurate swinging of the swing assembly 131. The pulley 1314 is located between the two arc-shaped guide rails 1312, and the contact surfaces of the two arc-shaped guide rails 1312 and the second fixed plate 1321 are defined as the first contact surface and the second contact surface, respectively. The contact surface of the pulley 1314 and the second fixed plate 1321 is defined as the third contact surface. The first contact surface, the second contact surface and the third contact surface are on the same horizontal plane, so that the pulley 1314 and the arc-shaped guide rail 1312 can be accurately installed, so that the swing assembly 131 can achieve smooth arc motion.
[0046] As a way to achieve this, Figure 6 As shown, the clamping assembly 132 also includes a limit piece 1325. The crystal support device 14 moves in the receiving groove 1324 along the length direction of the wire cutting machine 100 until it abuts against the limit piece 1325. Through the interaction between the receiving groove 1324 and the limit piece 1325, the movement of the crystal support device 14 is restricted to prevent the crystal support device 14 from accidentally moving or sliding when moving in the receiving groove 1324, thereby improving the installation accuracy and stability of the crystal support device 14.
[0047] As a way to achieve this, Figure 6 As shown, the clamping assembly 132 further includes a vent hole 1326, which is disposed on the second fixing plate 1321, that is, the vent hole 132 passes through the second fixing plate 1321 along the height direction, and the swing chamber 1313 is connected to the receiving groove 1324 via the vent hole 1326 to detect whether the crystal support device 14 is clamped.
[0048] Specifically, when the clamping assembly 132 clamps the crystal support device 14, the vent 1326 is blocked by the crystal support device 14. At this time, the inside of the swing chamber 1313 is pressurized. If there is no gas leakage, a certain pressure will be maintained inside the swing chamber 1313, indicating that the crystal support device 14 is tightly clamped by the clamping assembly 132; if there is a gas leakage, the internal pressure of the swing chamber 1313 will decrease, indicating that the seal is still incomplete, that is, the vent 1326 is not blocked by the crystal support device 14, and it is necessary to further check the clamping process and clamping state of the crystal support device 14 to facilitate timely resolution of the clamping problem of the crystal support device 14.
[0049] In summary, by setting up a multi-layer waterproof sealing structure, such as the first protective cover 1331, the second protective cover 1332 and the humidity sensor 134 mentioned above, it is ensured that the cutting liquid cannot enter the swing chamber 1313 during the crystal rod cutting process, and the waterproof sealing effect of the wire cutting machine 100 is improved, so that the wire cutting machine 100 can work stably. In addition, the arrangement of the first clamping mechanism 1322 and the second clamping mechanism 1323 makes the overall structure of the wire cutting machine 100 more compact.

[0051] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
