Description

Technical Field

[0001] This application relates to the field of crystal processing equipment technology, specifically to a crystal shearing device. Background Technology

[0002] During the crystal ingot production process, after the crystal ingot has finished growing in the single crystal furnace, it needs to be removed from the furnace. When removing the crystal, the ingot to be removed must first be clamped and held, and then the part of the ingot connected to the seed crystal (i.e., the narrow neck section) is cut off.

[0003] The applicant disclosed a crystal shearing device in Chinese Utility Model Patent CN221166844U. This device has an anti-twist plate with a limiting groove. During crystal shearing, the limiting groove limits the narrow neck segment. However, in production, it was found that due to the uneven thickness of the narrow neck segment, if the limiting groove of the anti-twist plate is too narrow, the narrow neck segment cannot easily enter the limiting groove for fixation; if the limiting groove is too wide, the narrow neck segment may wobble after entering, failing to be properly fixed. This adversely affects the smooth operation of crystal shearing. Therefore, it is necessary to improve the existing crystal shearing device to solve the above problems. Utility Model Content

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application provides a crystal shearing device to solve the problem that existing crystal shearing devices, when processing thin neck segments with uneven thickness, suffer from poor fixing effect due to unreasonable limiting methods, which in turn affects the smooth crystal shearing process.

[0005] The objective of this application can be achieved through the following technical solutions:

[0006] This application provides a crystal shearing device, which includes:

[0007] Base plate;

[0008] A shearing mechanism is mounted on the base plate. The shearing mechanism is configured to perform a shearing action on the narrow neck section, which is the part where the top of the crystal rod connects to the seed crystal.

[0009] The clamping mechanism includes a first clamping part and a second clamping part disposed opposite to each other. The first clamping part and the second clamping part are configured to clamp a thin neck segment. Both the first clamping part and the second clamping part include a clamping plate, an elastic component and a mounting plate. The clamping plate is located above the shearing mechanism and is connected to the mounting plate through the elastic component. The elastic component is configured to release pressure through elastic deformation when the clamping plate clamps the thin neck segment.

[0010] The drive mechanism is configured to drive the shearing mechanism to perform the shearing action.

[0011] By setting up a clamping mechanism, the clamping plate of the clamping mechanism located above the shearing mechanism can firmly clamp the thin neck section before the shearing mechanism performs shearing, thereby improving the shearing efficiency; in addition, the clamping plate is not limited to the thickness variation of the thin neck section, and can accommodate various thickness variations of the thin neck section.

[0012] Optionally, the shearing mechanism includes a first blade holder, a second blade holder, a first blade, and a second blade, wherein the first blade is detachably mounted on the mounting end of the first blade holder; and the second blade is detachably mounted on the mounting end of the second blade holder.

[0013] The first and second tool holders are arranged symmetrically and intersecting, and the intersection of the first and second tool holders is hinged by a first pin mounted on the base plate. The drive mechanism drives the first and second tool holders to rotate relative to each other around the first pin, so as to drive the first blade and the second blade to close or open relative to each other.

[0014] The detachable blade installation facilitates blade replacement. When the blade wears or is damaged after long-term use, a new blade can be quickly replaced without replacing the entire shearing mechanism, reducing maintenance costs and ensuring the continuous and efficient operation of the crystal shearing device.

[0015] Optionally, the mounting plate of the first clamping part is fixedly mounted on the first tool holder, and the mounting plate of the second clamping part is fixedly mounted on the second tool holder. When the first tool holder and the second tool holder rotate relative to each other around the first pin, they synchronously drive the first blade and the second blade, as well as the clamping plate on the first clamping part and the clamping plate on the second clamping part, to close or open relative to each other.

[0016] The mounting plates of the first clamping part and the second clamping part are respectively fixed on the first knife handle and the second knife handle, so that the rotational motion of the knife handle can be directly transmitted to the clamping plate of the clamping part, realizing the synchronous opening and closing action of the clamping plate and the blade, and enabling the clamping mechanism and the shearing mechanism to be driven by the same drive source.

[0017] Optionally, the opening angle between the clamping plates on the first clamping part and the clamping plates on the second clamping part is equal to the opening angle between the first blade and the second blade, and the openings face the same direction.

[0018] The opening angle between the two clamping plates is equal to the opening angle between the two blades, and the openings face the same direction. This ensures that the clamping force and the shearing force act in the same direction during the crystal shearing operation. It avoids displacement or damage to the thin neck section due to uneven force during shearing caused by angular deviation. This ensures that the clamping mechanism and the shearing mechanism always maintain coordinated cooperation, improves the accuracy and success rate of crystal shearing, ensures the quality of crystal shearing, reduces the scrap rate, and improves the production quality of the product.

[0019] Optionally, the clamping mechanism further includes a mounting bracket, and the driving mechanism includes a first driving member and a second driving member. The first driving member is mounted on the base plate, and the driving end of the first driving member is connected to the shearing mechanism in a transmission manner. The first driving member is configured to drive the shearing mechanism to perform a shearing action. The second driving member is mounted on the mounting bracket, and the driving end of the second driving member is connected to the first clamping part and the second clamping part in a transmission manner. The second driving member is configured to drive the clamping mechanism to perform a clamping action.

[0020] By setting up a first driving component and a second driving component to drive the shearing mechanism and the clamping mechanism respectively, independent control of the shearing and clamping actions is achieved, improving the flexibility and operational accuracy of the device.

[0021] Optionally, non-metallic isolation pads are provided on the sides of the clamping plates of the first clamping part and the clamping plates of the second clamping part that are close to each other.

[0022] The non-metallic isolation pads on the opposite sides of the clamping plate can prevent the clamping plate from directly contacting the narrow neck section, thus avoiding metal contamination of the crystal rod during clamping.

[0023] Optionally, the elastic component includes a guide post and a spring. The guide post is disposed between the mounting plate and the clamping plate. The first end of the guide post is fixedly connected to the side of the clamping plate near the mounting plate, and the second end of the guide post is slidably engaged with the mounting plate. The spring is sleeved on the guide post, and the two ends of the spring abut against the clamping plate and the mounting plate, respectively.

[0024] The elastic assembly consisting of guide posts and springs not only enables the clamping plate to release pressure through elastic deformation during clamping, ensuring the shearing mechanism is fully closed, but also provides stable guidance for the movement of the clamping plate through the sliding fit between the guide posts and the mounting plate. The elasticity of the springs allows the clamping plate to automatically adjust the clamping force under different neck diameters, ensuring clamping stability. At the same time, during the opening and closing of the shearing mechanism, the guide posts prevent the clamping plate from shifting or wobbling, further improving the reliability and accuracy of the entire clamping mechanism.

[0025] Optionally, the shearing device also includes a substrate and a rotating mechanism. The substrate is mounted on the substrate at a certain angle via the rotating mechanism, so as to drive the shearing mechanism to adapt to the twisting angle.

[0026] The base plate can be rotated and mounted on the substrate at a certain angle via a rotating mechanism, allowing the shearing and clamping mechanisms to adapt to situations such as the neck segment being out of center. When the neck segment is slightly off-center, the entire shearing device can automatically adjust its angle to ensure that the shears are accurately aligned with the neck segment for shearing. This improves the adaptability of the shearing device to neck segments in different positions and reduces shearing failures or poor shearing quality caused by inaccurate neck segment positioning.

[0027] Optionally, a slotted photoelectric sensor is provided on one of the base plate and the substrate, and a photoelectric sensing sheet corresponding to the slotted photoelectric sensor is provided on the other of the base plate and the substrate. When the base plate is twisted and reset, the photoelectric sensing sheet is located in the photoelectric sensing area of ​​the slotted photoelectric sensor.

[0028] The combined use of slotted photoelectric sensors and photoelectric induction plates provides precise detection and positioning functions for the torsion reset of the base plate, ensuring that the mechanism can accurately return to the initial position after each shearing operation, preparing for the next crystal shearing operation, and improving the repeatability and stability of the entire crystal shearing process.

[0029] Optionally, the crystal shearing device also includes a support column, a lifting mechanism, and a translation mechanism, wherein:

[0030] The support column is installed vertically, and the lifting mechanism is installed on the support column;

[0031] The translation mechanism is located at the drive end of the lifting mechanism, and the lifting mechanism is configured to drive the translation mechanism to move up and down along the support column;

[0032] The substrate is set at the drive end of the translation mechanism, which is configured to drive the shearing mechanism and the clamping mechanism to move toward or away from the thin neck segment to be sheared by driving the substrate.

[0033] The support column provides vertical support for the entire crystal shearing device. The lifting mechanism can adjust the vertical positions of the translation mechanism, shearing mechanism, and clamping mechanism to adapt to the crystal ingot shearing requirements of different heights. The translation mechanism can precisely control the horizontal movement of the shearing mechanism and clamping mechanism, achieving accurate clamping and shearing of narrow neck sections. The coordinated operation of these three components allows the crystal shearing device to flexibly manipulate crystal ingots in three-dimensional space, greatly improving its applicability and working efficiency, and meeting the crystal shearing tasks under different production environments and process requirements.

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] Please see Figure 2-4 As shown, in some embodiments, this application provides a crystal shearing device, which includes a base plate 100, a shearing mechanism 110, a clamping mechanism 120, and a driving mechanism 130. The base plate 100 serves as a basic support platform, providing an installation reference for other components. The shearing mechanism 110 is mounted on the base plate 100 and is specifically used to perform shearing operations on the narrow neck section where the top of the crystal rod connects to the seed crystal.

[0053] The clamping mechanism 120 consists of a first clamping part 121 and a second clamping part 122 arranged opposite to each other, used to securely clamp the thin neck segment. Each clamping part includes a clamping plate 123, an elastic component 124, and a mounting plate 128. The clamping plate 123 is located above the shearing mechanism 110 and is connected to the mounting plate 128 through the elastic component 124. When the clamping plate 123 clamps the thin neck segment, the elastic component 124 undergoes elastic deformation to release pressure, ensuring that the two clamping plates 123 can be fully closed to achieve stable clamping. The drive mechanism 130 is responsible for providing power to the shearing mechanism 110 and driving it to complete the shearing action. It can be a power device such as a motor or cylinder, connected to the shearing mechanism 110 through a transmission component to transmit power.

[0054] By incorporating a clamping mechanism 120 that can flexibly adapt to variations in the thickness of the neck segment, the neck segment is firmly clamped before shearing, significantly improving shearing efficiency. The elastic component 124 is designed to automatically adjust the clamping force according to the actual condition of the neck segment, ensuring stable clamping unaffected by uneven thickness of the neck segment.

[0055] Please see Figure 3 and Figure 4 As shown, in one possible embodiment, the shearing mechanism 110 includes a first handle 111, a second handle 112, a first blade 113, and a second blade 114. The first blade 113 is detachably mounted on the mounting end of the first handle 111 via bolt connection, snap-fit, or other means. The second blade 114 is detachably mounted on the mounting end of the second handle 112 in the same manner, facilitating replacement when the blades are worn or damaged. The first handle 111 and the second handle 112 are arranged crosswise and symmetrically, and their intersection is hinged by a first pin 115 mounted on the base plate 100. When the drive mechanism 130 is working, it drives the first handle 111 and the second handle 112 to rotate relative to each other around the first pin 115. During rotation, the movements of the first handle 111 and the second handle 112 cooperate with each other, like the opening and closing action of scissors, thereby causing the first blade 113 and the second blade 114 to close or open relative to each other, achieving the shearing of narrow neck sections.

[0056] In this embodiment, the transmission component may include a first connecting rod 131 and a second connecting rod 132. The first end of the first connecting rod 131, the first end of the second connecting rod 132, and the driving end of the driving component are hinged together by a second pin. The second end of the first connecting rod 131 is hinged to the connecting end of the first blade holder 111 via a third pin, and the second end of the second connecting rod 132 is hinged to the connecting end of the second blade holder 112 via a fourth pin. Through the transmission component composed of the first connecting rod 131, the second connecting rod 132, and the pins, the linear drive of the driving mechanism 130 is converted into the relative rotational motion of the first blade holder 111 and the second blade holder 112. This transmission method has a compact structure and can effectively transmit the power of the driving component to the scissor component, achieving precise opening and closing control. Simultaneously, utilizing the characteristics of the linkage mechanism, the opening and closing angle and speed of the scissor component can be adjusted as needed to adapt to different crystal cutting requirements, improving the flexibility and versatility of the crystal cutting mechanism.

[0057] Please see Figure 3 and Figure 4 As shown, in one possible embodiment, the mounting plate 128 of the first clamping part 121 is firmly fixed to the first tool holder 111 by welding, bolting, or other means, and the mounting plate 128 of the second clamping part 122 is similarly fixed to the second tool holder 112. When the first tool holder 111 and the second tool holder 112 rotate relative to each other around the first pin 115, due to the fixed connection between the mounting plate 128 and the tool holder, the rotation of the tool holder is directly transmitted to the mounting plate 128, thereby causing the clamping plates 123 on the first clamping part 121 and the clamping plates 123 on the second clamping part 122 to synchronously close or open relative to each other, and also causing the first blade 113 and the second blade 114 to move synchronously. Throughout the entire movement, the movements of each component are coordinated and consistent, ensuring the synchronicity of the clamping and shearing actions.

[0058] This structural design allows the clamping mechanism 120 and the shearing mechanism 110 to be driven by the same drive source, simplifying the drive structure of the device, reducing the number and complexity of parts, and lowering equipment costs. At the same time, it improves the coordination and stability of the mechanism's movements, ensuring smooth crystal shearing and improving the quality and efficiency of crystal shearing.

[0059] In another possible embodiment, the clamping mechanism 120 further includes a mounting bracket (not shown), and the drive mechanism 130 is further refined into a first drive member (not shown) and a second drive member (not shown). The first drive member is mounted on the base plate 100, and its drive end is connected to the shearing mechanism 110 via a transmission component such as a transmission rod. When the first drive member is activated, power is transmitted to the shearing mechanism 110 through the transmission component, driving it to perform the shearing action. The second drive member is mounted on the mounting bracket, and its drive end is connected to the first clamping part 121 and the second clamping part 122 via a transmission structure such as a connecting rod and a slider. When the second drive member is working, it drives the clamping plate 123 of the clamping part to open and close, realizing the clamping operation of the thin neck section. Of course, the second drive member can also be a thumb cylinder, omitting the relevant transmission structure, and the first clamping part 121 and the second clamping part 122 are directly fixed on the two thumbs of the thumb cylinder.

[0060] The independent configuration of the first and second driving components allows for separate control of the shearing and clamping actions. In actual operation, the timing and force of shearing and clamping can be flexibly adjusted according to different working requirements and the condition of the crystal rod, improving the operational flexibility and precision of the device. This design also facilitates the debugging and maintenance of the device, enhancing its practicality and reliability.

[0061] Please see Figure 3 As shown, in one possible implementation, the opening angle between the clamping plate 123 on the first clamping part 121 and the clamping plate 123 on the second clamping part 122 remains equal to the opening angle between the first blade 113 and the second blade 114 throughout the entire working process, and the openings face the same direction.

[0062] The opening angle between the two clamping plates 123 is equal to the opening angle between the two blades, and the openings face the same direction. This ensures that the clamping force and the shearing force act in the same direction during the crystal shearing operation. It avoids displacement or damage to the thin neck section due to uneven force during shearing caused by angular deviation. This ensures that the clamping mechanism 120 and the shearing mechanism 110 always maintain coordinated cooperation, improves the accuracy and success rate of crystal shearing, ensures the quality of crystal shearing, reduces the scrap rate, and improves the production quality of the product.

[0063] Please see Figure 3 As shown, in one possible embodiment, non-metallic isolation pads 129 are provided on the sides of the clamping plates 123 of the first clamping part 121 and the clamping plates 123 of the second clamping part 122 that are close to each other. The pads 129 are typically made of high-temperature resistant plastic and are fixed to the clamping plates 123 by means of adhesive bonding, slot embedding, or other methods. When clamping the narrow neck section, the pads 129 are located between the clamping plates 123 and the narrow neck section, effectively isolating the clamping plates 123 from direct contact with the narrow neck section.

[0064] The non-metallic isolation pad 129 can prevent the clamping plate 123 from directly contacting the narrow neck of the crystal rod during the clamping process, thus avoiding metal contamination of the crystal rod.

[0065] Please see Figure 3 As shown, in one possible embodiment, the elastic component 124 includes a guide post 125 and a spring 126. The guide post 125 is disposed between the mounting plate 128 and the clamping plate 123, and is perpendicular to the extension direction of the blade edge of the corresponding blade. The first end of the guide post 125 is firmly fixed to the side of the clamping plate 123 near the mounting plate 128 by welding, integral molding, or other methods to ensure reliable connection. The second end of the guide post 125 is slidably engaged with the mounting plate 128 through an oil-free bushing 127. The oil-free bushing 127 is fixedly installed on the side of the mounting plate 128 away from the clamping plate 123. The mounting plate 128 has a through hole that allows the second end of the guide post 125 to pass through. The second end of the guide post 125 passes through the through hole in the mounting plate 128 and slidably engages with the oil-free bushing 127, allowing the guide post 125 to slide smoothly relative to the mounting plate 128. The spring 126 is sleeved on the guide post 125, with both ends tightly abutting against the clamping plate 123 and the mounting plate 128, respectively. When the clamping plate 123 clamps the narrow neck section, the spring 126 undergoes elastic deformation under force, which plays a role in relieving pressure. At the same time, the guide post 125 provides stable guidance for the movement of the clamping plate 123.

[0066] The elastic component 124 provides elastic pressure relief for the clamping plate 123 during clamping, ensuring the shearing mechanism 110 is fully closed and improving the shearing effect. The sliding fit between the guide post 125 and the mounting plate 128 provides stable guidance for the movement of the clamping plate 123, preventing the clamping plate 123 from shifting or wobbling during movement. The elasticity of the spring 126 allows the clamping plate 123 to automatically adjust the clamping force according to the thickness of the narrow neck section, ensuring clamping stability and further improving the reliability and accuracy of the entire clamping mechanism 120, thus enhancing the working performance of the crystal shearing device.

[0067] Please see Figure 3 and Figure 4As shown, in one possible embodiment, the crystal shearing device further includes a substrate 140 and a rotating mechanism 150. The base plate 100 is mounted on the substrate 140 at a certain angle via the rotating mechanism 150. The rotating mechanism 150 can be one of a crossed roller bearing, a deep groove ball bearing, or an angular contact bearing, or a combination of a shaft and a bushing. Preferably, the rotating mechanism 150 can be a crossed roller bearing, making the rotating mechanism 150 sufficiently flat and reducing the space occupied by the rotating mechanism 150. The base plate 100 is mounted on the inner or outer ring of the crossed roller bearing, and the substrate 140 is connected to another part of the crossed roller bearing. When the thin neck section is not in the center position, due to the weight of the crystal rod, the thin neck section will pull the entire shear. At this time, the rotating mechanism 150 provides rotational freedom for the shear, allowing the base plate 100 to drive the shearing mechanism 110 to adaptively rotate the angle, ensuring that the shear can accurately align with the thin neck section for shearing.

[0068] Please see Figure 3 As shown, in one possible implementation, a slotted photoelectric sensor 160 is disposed on one of the base plate 100 and the substrate 140, and a corresponding photosensitive element 170 is disposed on the other. For example, the slotted photoelectric sensor 160 is mounted on the base plate 100, and the photosensitive element 170 is mounted on the substrate 140, or vice versa. During device operation, when the base plate 100 is twisted and reset, the photosensitive element 170 will accurately enter the photosensitive area of ​​the slotted photoelectric sensor 160. During installation, the positions and angles of the slotted photoelectric sensor 160 and the photosensitive element 170 need to be precisely adjusted to ensure the accuracy and reliability of the detection.

[0069] Please see Figure 1 and Figure 2As shown, in one possible embodiment, the crystal shearing device further includes a support column 180, a lifting mechanism 190, and a translation mechanism 200. The support column 180 is arranged vertically, providing stable vertical support for the entire device. The lifting mechanism 190 is mounted on the support column 180. Its driving method can be a motor driving a lead screw and nut; when the motor rotates, the lead screw rotates accordingly, causing the nut to move up and down along the support column 180. Alternatively, it can be hydraulically driven, using the pressure of hydraulic oil to push a piston, thus achieving the lifting and lowering of the lifting mechanism 190. The translation mechanism 200 is located at the drive end of the lifting mechanism 190. The translation mechanism 200 can also be driven by a lead screw and nut in conjunction with a motor; when the motor rotates, the lead screw rotates accordingly, causing the nut to move horizontally, thereby achieving the horizontal movement of the translation mechanism 200. The substrate 140 is disposed at the drive end of the translation mechanism 200. When the lifting mechanism 190 is working, it drives the translation mechanism 200 to rise and fall along the support column 180, adjusting the position of the device in the vertical direction. When the translation mechanism 200 is working, it drives the substrate 140 to move the shearing mechanism 110 and the clamping mechanism 120 in the horizontal direction toward or away from the thin neck section to be sheared, so as to realize accurate clamping of the thin neck section and shearing of the connecting part.

[0070] The support column 180, lifting mechanism 190, and translation mechanism 200 work together to enable the crystal shearing device to operate flexibly in three-dimensional space. The lifting mechanism 190 can adjust the device position according to the different heights of the crystal rod, while the translation mechanism 200 can precisely control the horizontal movement of the shearing mechanism 110 and the clamping mechanism 120, achieving precise positioning and operation of the narrow neck section. This design greatly improves the applicability and working efficiency of the crystal shearing device, meeting the crystal shearing tasks under different production environments and process requirements, and enhancing the equipment's versatility and practicality.

[0071] The working principle of a crystal shearing device combining the above embodiments is described below as an example:

[0072] The lifting mechanism 190 and the translation mechanism 200 operate separately (the order of operation is not limited), lifting and translating the shearing mechanism 110 (if the clamping mechanism 120 is set on the shearing mechanism 110, it moves together with the shearing mechanism 110; if the clamping mechanism 120 is set independently, it remains in its original position) to the position corresponding to the narrow neck section of the crystal rod to be sheared (i.e., the position of the narrow neck section within the shearing area of ​​the first blade 113 and the second blade 114).

[0073] If the clamping mechanism 120 is set independently, the second driving member first drives the clamping mechanism 120 to clamp the thin neck section, and the first driving member drives the first blade 113 and the second blade 114 to close relative to each other to cut the thin neck section.

[0074] If the clamping mechanism 120 is mounted on the shearing mechanism 110, the drive mechanism drives the first blade 113 and the second blade 114 to close relative to each other, and simultaneously drives the first clamping part 121 and the second clamping part 122 mounted on the two blade holders to close relative to each other. As the clamping plates 123 of the first clamping part 121 and the second clamping part 122 gradually approach each other and clamp the narrow neck section, the elastic component 124 releases pressure, allowing the first blade 113 and the second blade 114 to close further, completing the shearing.

[0075] If the base plate 100 twists during shearing, the rotation mechanism 150 compensates for the twist angle, and the slotted photoelectric sensor 160 and the photoelectric sensor 170 confirm whether the base plate 100 has been reset.
