Description

[0001] The utility model relates to the technical field of hard and brittle material cutting, in particular to a rod body stabilizing mechanism and a cutting machine. Background Art

[0002] In the processing of single crystal silicon rods, the cutting process is an important link. However, existing cutting devices often encounter some problems when processing single crystal silicon rods, especially when processing short rod materials. When a single crystal silicon rod is cut into shorter rod bodies, these short rod materials are likely to sink on the roller rack because their lengths are less than the preset spacing between the rollers on the roller rack, resulting in the rod body being unable to stay stably on the roller rack. This situation not only affects the normal progress of subsequent processes but may also cause equipment damage or product quality problems.

[0003] Most of the existing cutting devices on the market do not fully consider the support problem of short rod materials in their designs. When short rod materials appear during the cutting process, operators need to manually intervene or take additional measures to support the short rod materials, increasing the complexity of the operation and the labor intensity. In addition, manual intervention cannot completely avoid the risk of short rod materials sinking between the roller racks, affecting the production efficiency and the stability of product quality.

[0029] To describe in detail the technical content, achieved purpose and effects of the present invention, the following is described in conjunction with the implementation manners and with reference to the accompanying drawings.

[0030] Please refer to Figures 1 to 6 , a rod body stabilizing mechanism, including a roller frame 1 and a floating support component 2;

[0031] The roller frame 1 includes at least two roller rows 11 arranged symmetrically, and each roller row 11 is provided with rollers arranged at a preset spacing;

[0032] The floating support component 2 is arranged between the roller rows 11. The floating support component 2 includes a first driving part 21 and a support part 22. The first driving part 21 is used to drive the support part 22 to perform a lifting movement, and the length of the support part 22 is greater than the preset spacing. Specifically, the preset spacing in this example is expressed as the distance between the centers of two adjacent rollers in a roller row.

[0033] From the above description, it can be seen that the beneficial effect of the present invention is: to provide a rod body stabilizing mechanism, which is mainly applied to a cutting device for single crystal silicon rods. A floating support component 2 is arranged between the roller rows 11. The floating support component 2 uses a driving part to realize the lifting of the support part 22. In the case of a short rod with a length less than the preset spacing between the rollers, the floating component is used to support the short rod, avoiding the short rod from falling between the roller frames 1 and improving the stability of the operation of the corresponding device.

[0034] It can be understood that the floating support assembly 2, as a part of the mechanism, can be used to provide support for short rods (with a length less than the preset spacing) in any situation where short rods appear, such as providing stable support at the bottom of the single crystal silicon rod at the cutting position of the single crystal silicon rod or at the temporary storage position of the single crystal silicon rod; at the same time, under the working condition where no support is required, the first drive part 21 controls the support part 22 to rise and fall to avoid blocking the transportation of the single crystal silicon rod.

[0035] Please refer to Figures 1 to 4 , further comprising a clamping jaw assembly 3, wherein the clamping jaw assembly 3 is disposed between the roller rows 11;

[0036] The clamping jaw assembly 3 includes a fixed baffle 31 , a clamping plate 32 , a second driving portion 33 and a mounting platform 34 . The fixed baffle 31 and the clamping plate 32 are arranged on the mounting platform 34 . The second driving portion 33 is used to drive the clamping plate 32 to move closer to or away from the fixed baffle 31 .

[0037] As can be seen from the above description, by adding the clamping jaw assembly 3, through the cooperation of the clamping plate 32 and the fixed baffle 31, the clamping jaw assembly 3 can further stabilize the position of the rod body, especially when it is necessary to fix or clamp the rod body, provide additional support and fixing capabilities, and improve stability. Specifically, the clamping jaw assembly 3 can be used to clamp the unloading rod body. When the unloading rod body is transported to the setting position of the clamping jaw assembly 3, one end of the rod body is held against the fixed baffle 31, and the clamping plate 32 is subsequently driven to gradually approach the fixed baffle 31 to complete the stable clamping of the rod body, thereby preventing the short rod from being placed on the roller frame 1 and falling. Preferably, the clamping jaw assembly 3 can also be used to collect slices of single crystal silicon rods.

[0038] Please refer to Figures 3 to 4 Furthermore, the clamping jaw assembly 3 also includes a guide wheel 35 and a guide rail 36 parallel to the axial direction of the roller frame 1; the guide rail 36 is arranged on the mounting platform 34, the guide wheel 35 is arranged on the clamping plate 32 and the guide wheel 35 can move along the axial direction of the guide rail 36.

[0039] From the above description, it can be seen that the setting of the guide wheel 35 and the guide rail 36 ensures that the clamping plate 32 can move axially along the guide rail 36, ensures that the direction of the clamping force during the clamping process is stable, makes the clamped short rod or slice stable in force, avoids damage to the single crystal silicon rod due to sudden changes in the clamping force point, and improves the flexibility and applicability of the mechanism.

[0040] Specifically, the second driving part 33 is a cylinder, and the guide rail 36 is arranged between the cylinder and the fixed baffle 31. Using a cylinder as the second driving part 33 to drive the clamping plate 32 to move can achieve fast and stable clamping and releasing operations, simplify the structural design, and improve the efficiency and reliability of the clamping operation. At the same time, using a cylinder as the driving part can control the clamping force. For rod types, a high-pressure mode can be used for clamping, and for slice types, a low-pressure mode can be used for clamping to avoid damaging the slices. Preferably, the second driving part further includes a pressure controller, which has two modes: low-pressure clamping and high-pressure clamping. Both modes control the pressure generated after the cylinder is ventilated through command transmission to control and switch the clamping force, realizing the switching between the above high-pressure mode and low-pressure mode.

[0041] Furthermore, the clamping plate 32 assembly further includes a dust cover 37, and the dust cover 37 is arranged above the guide wheel 35 and connected to the clamping plate 32.

[0042] As can be seen from the above description, since the cut rod or slice inevitably has some residues or dust invisible to the naked eye, these impurities are likely to mix into some components during the operation of the mechanism, resulting in component wear. To solve this problem, a dust cover 37 is arranged above the guide wheel 35, which can effectively protect the guide wheel 35 from the influence of dust and debris, extend the service life of the equipment, ensure the stable operation of the jaw assembly 3, and reduce the maintenance cost.

[0043] Furthermore, the jaw assembly 3 further includes a buffer plate 38, and the buffer plate 38 is respectively arranged on the opposite end faces of the fixed baffle 31 and the clamping plate 32.

[0044] As can be seen from the above description, the setting of the buffer plate 38 can provide a buffering effect during the clamping process, reduce the impact and wear caused by the direct contact between the clamping plate 32 and the fixed baffle 31, protect the surface of the rod, and at the same time, the buffer plate 38 is easy to replace, which can extend the service life of the jaw assembly 3.

[0045] Furthermore, the jaw assembly 3 further includes a third driving part 39, and the third driving part 39 is used to control the installation platform 34 to approach or move away from the roller rack 1.

[0046] As can be seen from the above description, the third driving part 39 can control the height of the installation platform 34, enabling the jaw assembly 3 to operate at different height positions, providing a more flexible clamping and supporting method, and adapting to the operation requirements at different heights.

[0047] Please refer to Figures 5 to 6, Further, the support portion 22 includes a support platform 221 and symmetrically arranged support plates 222. The support plates 222 are disposed on the upper end surface of the support platform 221, and the driving portion is connected to the lower end surface of the support platform 221.

[0048] As can be seen from the above description, the support platform 221 and the symmetrically arranged support plates 222 provide a stable support structure. The symmetric design of the support plates 222 can distribute the force more evenly, avoid tilting or offset of the support portion 22, and improve the stability of the support. Specifically, the included angle between the support plates 222 and the horizontal plane is an acute angle. When using the support plates 222 to support the single crystal silicon rod, the center of gravity of the single crystal silicon rod is automatically adjusted between the two support plates 222 under the action of gravity, thereby ensuring the stability of the support.

[0049] Further, the number of the support portions 22 is greater than or equal to two, and the first driving portion 21 drives the support portions 22 to perform lifting movements respectively.

[0050] As can be seen from the above description, during the cutting process of the single crystal silicon rod, there may be two or more short rods. In order to prevent the short rods from falling, the number of the support portions 22 is set to be greater than or equal to two to meet the production requirements. In addition, since the support portion 22 provides the support function through lifting, in order to avoid excessive inertial force caused by lifting and causing the rod to be ejected, multiple support portions 22 can be selected to perform the support effect successively, thereby reducing the influence brought by the inertial force.

[0051] The present utility model provides a rod body stabilizing mechanism, which is mainly applied to solve the problem that the rod body on the roller frame 1 is prone to falling. The following is a specific description with reference to the embodiments.

[0052] Please refer to Figures 1 to 6 , Embodiment 1 of the present utility model is as follows:

[0053] A rod stabilizing mechanism includes a roller frame 1 and a floating support assembly 2; the roller frame 1 includes at least two roller rows 11 arranged symmetrically, and each roller row 11 is provided with rollers arranged at a preset spacing; the floating support assembly 2 is arranged between the roller rows 11, and the floating support assembly 2 includes a first driving part 21 and a support part 22. The first driving part 21 is used to drive the support part 22 to perform lifting motion, and the length of the support part 22 is greater than the preset spacing. That is, in this embodiment, the floating support assembly 2 is arranged between the roller rows 11. The floating support assembly 2 uses the driving part to realize the lifting of the support part 22. In the case of a short rod with a length less than the preset spacing between the rollers, the floating assembly is used to support the short rod to prevent the short rod from falling between the roller frames 1 and improve the stability of the operation of the corresponding device. Specifically, the floating support assembly 2 is applied to the cutting position of the corresponding device to support the short rod generated after cutting; or, it is applied to the rod storage position to support the temporarily placed rod.

[0054] Please refer to Figures 2 to 4 , Embodiment 2 of the present utility model is as follows:

[0055] On the basis of Embodiment 1, it further includes a jaw assembly 3, and the jaw assembly 3 is arranged between the roller rows 11; the jaw assembly 3 includes a fixed baffle 31, a clamping plate 32, a second driving part 33 and a mounting platform 34. The fixed baffle 31 and the clamping plate 32 are arranged on the mounting platform 34, and the second driving part 33 is used to drive the clamping plate 32 to approach or move away from the fixed baffle 31. Specifically, the jaw assembly 3 can be used to clamp the rod during blanking. When the blanking rod is transported to the position where the jaw assembly 3 is arranged, one end of the rod is abutted against the fixed baffle 31, and then the clamping plate 32 is driven to gradually approach the fixed baffle 31 to complete the stable clamping of the rod, preventing the short rod from falling when placed on the roller frame 1. At the same time, the jaw assembly 3 can also be used to collect the slices of the single crystal rod. At the same time, the jaw assembly has the following functions in the corresponding rod processing device: during the feeding or blanking process of the rod before and after processing, the rod is temporarily stored in the jaw assembly and is grabbed by an external manipulator or manually for feeding or blanking.

[0056] The jaw assembly 3 further includes a guide wheel 35 and a guide rail 36 parallel to the axial direction of the roller frame 1; the guide rail 36 is arranged on the mounting platform 34, and the guide wheel 35 is arranged on the clamping plate 32 and the guide wheel 35 can move along the axial direction of the guide rail 36. The arrangement of the guide wheel 35 and the guide rail 36 ensures that the clamping plate 32 can move axially along the guide rail 36, ensures the stability of the clamping force direction during the clamping process, enables the short rod or slice being clamped to be stressed stably, avoids situations such as sudden change of the clamping force action point from damaging the single crystal rod, and improves the flexibility and applicability of the mechanism.

[0057] The second driving part 33 is a cylinder, and the guide rail 36 is arranged between the cylinder and the fixed baffle 31. Using a cylinder as the second driving part 33 to drive the clamping plate 32 to move can achieve fast and stable clamping and releasing operations, simplify the structural design, and improve the efficiency and reliability of the clamping operation. At the same time, using a cylinder as the driving part can control the clamping force. For the rod type, normal clamping can be used, and for the slice type, low-pressure mode clamping can be used to avoid damaging the slices.

[0058] The clamping plate 32 assembly further includes a dust cover 37, and the dust cover 37 is arranged above the guide wheel 35 and connected to the clamping plate 32. Since the cut rod or slice inevitably has some residues or dust invisible to the naked eye, these impurities are likely to mix into some components during the operation of the mechanism, resulting in component wear. To solve this problem, a dust cover 37 is arranged above the guide wheel 35, which can effectively protect the guide wheel 35 from the influence of dust and debris, extend the service life of the equipment, ensure the stable operation of the jaw assembly 3, and reduce the maintenance cost.

[0059] The jaw assembly 3 further includes a buffer plate 38, and the buffer plate 38 is respectively arranged on the opposite end faces of the fixed baffle 31 and the clamping plate 32. The setting of the buffer plate 38 can provide a buffering effect during the clamping process, reduce the impact and wear caused by the direct contact between the clamping plate 32 and the fixed baffle 31, protect the surface of the rod, and at the same time, the buffer plate 38 is easy to replace, which can extend the service life of the jaw assembly 3.

[0060] The jaw assembly 3 further includes a second driving part 33, and the second driving part 33 is used to control the mounting platform 34 to approach or move away from the roller rack 1. The second driving part 33 can control the height of the mounting platform 34, so that the jaw assembly 3 can operate at different height positions, providing a more flexible clamping and supporting method to meet the operation requirements at different heights.

[0061] Please refer to Figures 5 to 6 , Embodiment 3 of the present utility model is:

[0062] On the basis of Embodiment 1, the support portion 22 includes a support platform 221 and symmetrically arranged support plates 222. The support plates 222 are provided on the upper end surface of the support platform 221, and the driving portion is connected to the lower end surface of the support platform 221. The support platform 221 and the symmetrically arranged support plates 222 provide a stable support structure. The symmetric design of the support plates 222 can distribute the force more evenly, avoid tilting or offset of the support portion 22, and improve the stability of the support. Specifically, the angle between the support plates 222 and the horizontal plane is an acute angle. When using the support plates 222 to support the single crystal silicon rod, the center of gravity of the single crystal silicon rod is automatically adjusted between the two support plates 222 under the action of gravity, thereby ensuring the stability of the support. At the same time, during the silicon rod cutting process, the equipment usually needs to spray a large amount of water for cooling and chip removal. The acute angle setting of the support plates 222 and the horizontal plane can well guide and drain the accumulated water during the cutting process.

[0063] Specifically, the number of the support portions 22 is two, and the first driving portion 21 drives the support portions 22 to move up and down respectively. During the cutting process of the single crystal silicon rod, short rods in two sections may appear. In order to prevent the short rods from falling, the number of the support portions 22 is set to two to meet the production requirements. In addition, since the support portion 22 provides a support function through lifting, in order to avoid excessive inertial force caused by lifting and causing the rod to be ejected, multiple support portions 22 can be selected to lift successively to complete the support effect, thereby reducing the influence brought by the inertial force. At the same time, an avoidance groove for the construction of the cutting wire is provided between the two support portions. During the cutting wire operation, the two support portions support the rod body at both ends of the cutting wire respectively to ensure the stability of the cutting process.

[0064] Please refer to Figure 7 , a rod body stabilizing mechanism provided by the present utility model is particularly applied to a rod body cutting machine. The cutting machine further includes a front anti-tilting suction cup assembly 4. When cutting a short rod, the jaw assembly 3 rises, and the short rod is placed in the jaw assembly 3 through a manipulator. Then, the front anti-tilting suction cup assembly 4 sucks the short rod, and the jaw assembly 3 descends. The short rod is stabilized on the roller rack. Then, through the front anti-tilting suction cup assembly 4, the short rod is pushed to the cutting position for cutting. It further includes a rear anti-tilting suction cup assembly 5. The two groups of suction cup assemblies can simultaneously adsorb on both end faces of the short rod to stabilize the short rod. After cutting (the cut rod material or sheet material can be cut according to actual requirements), the two groups of suction cup assemblies successively send the cut rod material or sheet material to the jaw assembly 3 for temporary storage, and the material is discharged by the manipulator. The jaw assembly 3 and the suction cup assembly are provided with corresponding avoidance structures. The two groups of suction cup assemblies are provided with moving mechanisms in corresponding directions and can move along the length direction and the vertical direction of the roller rack.

[0065] It has the following beneficial effects:

[0066] Provide stable support: By setting a floating support component between the roller rows and using the driving part to realize the lifting of the support part, in the case of a short bar with a length less than the preset distance between the rollers, the floating support component can effectively support the short bar, prevent the short bar from falling between the roller racks, and improve the stability of the device operation.

[0067] Enhance the clamping function: The jaw component can be used to clamp the bar being fed. Through the cooperation of the fixed baffle and the clamping plate, ensure the bar is stably clamped on the roller rack, prevent the short bar from falling, and can also be used to collect the slices of the single crystal bar.
