Description

Technical Field

[0001] This invention relates to the field of crystalline silicon processing equipment technology, and more specifically, to an edge-cutting device and a dual-station squaring device using the same. Background Technology

[0002] Monocrystalline silicon, as a key basic material in the modern semiconductor and photovoltaic industries, plays an irreplaceable role in integrated circuit manufacturing, solar cell production, and other fields. In the monocrystalline silicon production process, processing cylindrical monocrystalline silicon rods into square rods with specific cross-sectional shapes is a crucial step, better meeting the demands of subsequent processes such as battery module manufacturing. However, traditional monocrystalline silicon rod squaring technology and equipment face several pressing problems. First, most traditional monocrystalline silicon rod squaring equipment operates in a single-station mode. In this mode, the equipment can only square one monocrystalline silicon rod at a time; only after one rod is squared can the next be processed. This sequential processing method results in extremely low overall processing efficiency, far from meeting the ever-increasing production demands of the current market. With the rapid development of the photovoltaic industry and the continuous rise in demand for monocrystalline silicon from the semiconductor industry, improving the processing efficiency of monocrystalline silicon rod squaring has become an urgent need for industry development. Second, in terms of edge removal, a large amount of edge waste is generated during the monocrystalline silicon rod squaring process. The traditional method of edge cleaning is manual operation after the equipment is shut down. This method not only leads to frequent production interruptions, severely impacting production efficiency, but also involves high labor intensity for manual cleaning, and the cleaning effect is easily affected by human factors, making it impossible to guarantee the timeliness and stability of cleaning. Furthermore, during the removal of the edge skin, due to the coolant used in the cutting process, the edge skin is easily adsorbed by water onto the crystal rod, making it difficult for the grippers to remove the edge skin smoothly, further increasing the difficulty and time cost of edge skin cleaning. Summary of the Invention

[0003] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0004] To at least partially solve the above problems, the present invention provides an edge-cutting device, comprising:

[0005] Edge gripper mechanism, used to grip the edge leather;

[0006] The lateral drive mechanism is connected to the edge gripper mechanism and can drive the edge gripper mechanism to move and separate the edge skin from the crystal rod laterally.

[0007] The longitudinal drive mechanism is connected to the transverse drive mechanism and can drive the edge gripper mechanism on the transverse drive mechanism to cause longitudinal displacement and separation between the edge and the crystal rod.

[0008] Furthermore, the longitudinal drive mechanism includes: a base, a base frame mounted on the base, a lifting conveyor belt longitudinally arranged on the base frame, the front end of the lifting conveyor belt being connected to a lifting beam longitudinally slidably disposed in two inner sliding openings at the front of the base frame; and the front part of the lifting beam being connected to a transverse drive mechanism.

[0009] Furthermore, a balance shaft is mounted on the lifting beam, and balance wheels at both ends of the balance shaft are rolled relative to each other in two balance vertical grooves at the front of the base frame.

[0010] Furthermore, the lifting conveyor belt is a chain conveyor belt, and the chain of the chain conveyor belt is connected to the lifting beam by bolts.

[0011] Furthermore, the lateral drive mechanism includes: a lateral frame fixed to the front of the lifting beam, a laterally arranged bidirectional lead screw rotating in front of the lateral frame, and two side gripper mechanisms that are relatively slidably engaged on the bidirectional lead screw; one end of the bidirectional lead screw is connected to a separate drive motor assembled on the lateral frame.

[0012] Furthermore, the edge gripper mechanism includes: a slide assembly screwed onto a bidirectional lead screw, the slide assembly being connected to a movable frame slidably mounted on a transverse frame, two protrusions on the movable frame being slidably mounted in the top and bottom transverse grooves of the transverse frame respectively; sliding beams are slidably mounted in the upper and lower front and rear sliding grooves at the front end of the movable frame, the front ends of the two sliding beams being connected to gripper seats, the lower end of the inner side of the gripper seat being fixedly connected to a lower gripper, the upper gripper being slidably connected in the longitudinal sliding groove of the gripper seat, the middle part of the upper gripper being slidably mounted on a vertical shaft in the longitudinal sliding groove, and the outer side of the upper gripper being connected to a clamping cylinder installed on the outer side of the gripper seat; the rear ends of the two sliding beams are connected by a limiting slide rod slidably mounted in the limiting groove of the movable frame, and a tension spring is fixedly connected between the limiting slide rod and the movable frame.

[0013] Furthermore, the slide assembly includes: a first seat plate screwed onto a bidirectional lead screw, the first seat plate sliding on the inner side of the transverse frame, the first seat plate being fixed to one end of a polygonal guide rod, the middle part of the polygonal guide rod sliding in a transverse polygonal hole of the second seat plate, and the other end of the polygonal guide rod being fixed with an anti-loosening bolt for locking the second seat plate on the outside; the second seat plate being fixed to the movable frame, and the first seat plate and the second seat plate being connected by a compression spring sleeved on the polygonal guide rod.

[0014] Furthermore, the slide assembly also includes: a gear, which is fixedly connected to the middle of the axle, the axle is rotatably mounted on the second seat plate through two upper and lower wheel seats, a turntable is fixedly connected to the end of the axle, an off-axis is fixedly connected to the eccentric part of the turntable, the off-axis is rotatably connected to one end of the separation push rod, and the other end of the separation push rod is rotatably connected to the limiting slide rod; a rack is installed in the groove on the front side of the polygonal guide rod, and when the bidirectional screw controls the first seat plate to move towards the second seat plate and compresses the compression spring to a preset amplitude, the rack contacts the gear and meshes with the gear to rotate.

[0015] Furthermore, an adjusting screw is rotatably connected in the groove on the front side of the polygonal guide rod. The adjusting screw is threadedly connected to a rack that slides in the groove on the front side to control the rack to slide in the groove on the front side. The inner end of the anti-loosening bolt abuts against the adjusting screw.

[0016] A dual-station squaring equipment, including the edge-cutting device described in any one of the above claims, further includes: a base, on which a loading / unloading mechanism for loading or unloading monocrystalline silicon rods is installed, the loading / unloading mechanism being located between two stations on the base; a positioning mechanism for positioning and fixing the monocrystalline silicon rods and a cutting mechanism for cutting the monocrystalline silicon rods from round rods into square rods are installed on the base; the edge-cutting device is installed on the base and is used to control the separation of the edge-cutting device generated after the monocrystalline silicon rods are cut from the square rods.

[0017] Furthermore, in the dual-station squaring equipment, a sensing device is installed on the contact surface between the lower gripper and the edge skin. When the edge skin is clamped by the upper and lower grippers, if the sensing device does not detect the edge skin, the sensing device transmits a signal to the alarm, activates the alarm program, controls the clamping signal light to light up, and suspends the action being performed at this station and subsequent actions. Then, manual inspection is performed to avoid mechanical damage and product loss until the edge skin and debris in the station are completely removed. After carefully checking the relevant parameters such as the position of the feed head, the manual edge skin removal function can be used to restore the normal operation of the squaring machine.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] This invention provides an edge-cutting device that, through the coordinated operation of an edge-cutting gripper mechanism, a lateral drive mechanism, and a longitudinal drive mechanism, achieves the lateral and longitudinal displacement separation of the edge-cutting material from the crystal rod. The edge-cutting gripper mechanism can firmly grasp the edge-cutting material, while the lateral and longitudinal drive mechanisms provide sufficient power and precise displacement control to overcome the adsorption force between the edge-cutting material and the crystal rod, successfully separating the edge-cutting material from the crystal rod and effectively solving the problem of difficult edge-cutting removal. In addition, the dual-station squaring equipment of this invention is equipped with two stations, which can process two monocrystalline silicon rods simultaneously, realizing the parallelization of the production process. This is equivalent to completing twice the processing tasks in the same amount of time, significantly improving the processing efficiency of the equipment and better meeting the growing market demand for monocrystalline silicon square rods.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0035] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0036] The following is in conjunction with the appendix Figure 1-10 The present invention will be described in further detail below.

[0037] Example 1:

[0038] like Figures 1-10 As shown, the edge strip feeding device of the present invention includes: an edge strip gripper mechanism 100 for gripping the edge strip; a transverse drive mechanism 200 connected to the edge strip gripper mechanism 100 and capable of driving the edge strip gripper mechanism 100 to cause transverse displacement separation between the edge strip and the crystal rod; and a longitudinal drive mechanism 300 connected to the transverse drive mechanism 200 and capable of driving the edge strip gripper mechanism 100 on the transverse drive mechanism 200 to cause longitudinal displacement separation between the edge strip and the crystal rod.

[0039] The working principle and technical effects of the above scheme are as follows:

[0040] In the edge-cutting device of the present invention, the edge-cutting gripper mechanism 100 serves as the front-end execution component of the entire device. After the single-crystal silicon rod completes the squaring operation to generate edge-cutting, the edge-cutting gripper mechanism 100 can move to the position of the edge-cutting under the control of the transverse drive mechanism 200 and the longitudinal drive mechanism 300, and clamp the edge-cutting, firmly fixing it in place to prepare for subsequent separation operations. The transverse drive mechanism 200 is connected to the edge-cutting gripper mechanism 100. When the edge-cutting gripper mechanism 100 clamps the edge-cutting, the transverse drive mechanism 200 starts working, driving the clamped edge-cutting to move laterally relative to the crystal rod, thereby achieving separation of the edge-cutting from the crystal rod in the transverse direction. The longitudinal drive mechanism 300 is connected to the transverse drive mechanism 200, and the longitudinal drive mechanism 300 can drive the clamped edge-cutting relative to the crystal rod in the transverse direction. The crystal rod moves longitudinally, separating the edge skin from the crystal rod in the longitudinal direction. The edge skin feeding device of the present invention uses the edge skin gripper mechanism 100 to grip the edge skin, and then uses the transverse drive mechanism 200 and the longitudinal drive mechanism 300 to realize the displacement separation of the edge skin and the crystal rod in the transverse and longitudinal directions, respectively. This helps to overcome the adsorption force between the edge skin and the crystal rod, and smoothly separates the edge skin from the crystal rod, solving the problem of difficult edge skin removal. Compared with the traditional edge skin cleaning method, which requires manual operation after machine shutdown, which is not only inefficient but also causes production interruption, the edge skin feeding device of the present invention can automatically complete the gripping and separation operation of the edge skin without stopping the equipment, greatly reducing the time required for edge skin cleaning, improving the overall production efficiency, and making the single crystal silicon rod squaring production process more continuous and efficient.

[0041] Example 2:

[0042] like Figures 1-10 As shown, in the edge-cutting device of the present invention, the longitudinal drive mechanism 300 includes: a base 301, a base frame 302 mounted on the base 301, a longitudinally arranged lifting conveyor belt 303 on the base frame 302, the front end of the lifting conveyor belt 303 being connected to a lifting beam 304 longitudinally sliding in two inner sliding openings at the front of the base frame 302; the front part of the lifting beam 304 being connected to a transverse drive mechanism 200. A balance shaft 305 is rotatably mounted on the lifting beam 304, and balance wheels 306 at both ends of the balance shaft 305 are rolled relative to each other in two balance vertical grooves at the front of the base frame 302. The lifting conveyor belt 303 is a chain conveyor belt, and the chain of the chain conveyor belt is connected to the lifting beam 304 by bolts.

[0043] The working principle and technical effects of the above scheme are as follows:

[0044] In the edge-cutting device of the present invention, the longitudinal drive mechanism 300 is supported by a base 301, which provides a stable mounting platform for the entire mechanism. A base frame 302 is mounted on the base 301, serving as the main load-bearing and guiding structure. A longitudinally mounted lifting conveyor belt 303 on the base frame 302 is the power source for longitudinal displacement. When the lifting conveyor belt 303 operates, its front end is connected to a lifting beam 304 (specifically, the chain of the chain conveyor belt is bolted to the lifting beam 304). The movement of the lifting conveyor belt 303 drives the lifting beam 304 to slide longitudinally along the two inner sliding openings at the front of the base frame 302. The front of the lifting beam 304 is connected to the transverse drive mechanism 200. When the lifting beam 304 moves longitudinally, it drives the transverse drive mechanism 200 and the edge gripper mechanism 100 connected to the transverse drive mechanism 200 to move longitudinally together. A balance shaft 305 is mounted on the lifting beam 304. The balance wheels 306 at both ends of the balance shaft 305 roll relative to each other in the two balance vertical grooves at the front of the base frame 302. When the lifting beam 304 moves longitudinally under the drive of the lifting conveyor belt 303, the balance wheels 306 will roll in the balance vertical grooves, playing a balancing and guiding role, ensuring that the lifting beam 304 remains stable during longitudinal movement, avoiding tilting or shaking, so that the edge gripper mechanism 100 can drive the edge to move longitudinally more accurately and smoothly. In this invention, the lifting beam 304 is driven longitudinally by the lifting conveyor belt 303, providing stable and reliable longitudinal displacement power for the edge skin gripper mechanism 100. The chain conveyor belt has strong load-bearing capacity and transmission stability, ensuring sufficient force to overcome resistance such as adsorption between the edge skin and the crystal rod when driving the edge skin for longitudinal separation, allowing the edge skin to be smoothly separated longitudinally from the crystal rod. The balance shaft 305 and balance wheel 306 effectively balance and guide the lifting beam 304 during longitudinal movement. The balance wheel 306 rolls within the balance groove, limiting the lateral sway and tilt of the lifting beam 304, improving the accuracy and stability of longitudinal displacement.

[0045] Example 3:

[0046] like Figures 1-10 As shown, in the edge skin feeding device of the present invention, the transverse drive mechanism 200 includes: a transverse frame 201 fixed to the front of the lifting beam 304, a transversely arranged bidirectional screw 202 rotating in front of the transverse frame 201, and two edge skin gripper mechanisms 100 that are relatively slidably engaged on the bidirectional screw 202; one end of the bidirectional screw 202 is connected to a separate drive motor 203 assembled on the transverse frame 201.

[0047] The working principle and technical effects of the above scheme are as follows:

[0048] In the edge-feeding device of the present invention, the transverse drive mechanism 200 is based on the transverse frame 201, which is fixed to the front of the lifting beam 304, so that the transverse drive mechanism 200 can move with the longitudinal movement of the lifting beam 304 in the longitudinal drive mechanism, providing transverse displacement for the edge-feeding gripper mechanism 100 while also cooperating with longitudinal displacement; a bidirectional lead screw 202 is transversely arranged in front of the transverse frame 201, and two edge-feeding gripper mechanisms 100 are screwed onto the bidirectional lead screw 202, and these two edge-feeding gripper mechanisms 100 are relatively slidably engaged with the transverse frame 201; one end of the bidirectional lead screw 202 is connected to the separation drive motor 203 mounted on the transverse frame 201. When the separation drive motor 203 is started, it will drive the bidirectional lead screw 202 to rotate. Since the two edge-feeding gripper mechanisms 100 are engaged with the bidirectional lead screw 202 through threads, and the edge-feeding gripper mechanisms 100 are also slidably engaged with the transverse frame 201, the bidirectional drive mechanism 200 is also relatively slidably engaged with the bidirectional lead screw 202. The upper part restricts its rotation, causing the bidirectional lead screw 202 to rotate and drive the two edge skin gripper mechanisms 100 to make relative or opposite linear movements along the transverse frame 201, thereby adjusting the relative position of the two edge skin gripper mechanisms 100. This facilitates the control of the two edge skin gripper mechanisms 100 to grip and fix the edge skin on both sides. After the edge skin gripper mechanism 100 grips the edge skin, the opposite movement can drive the edge skin and the crystal rod to perform lateral displacement separation. In this invention, the bidirectional lead screw 202 is driven to rotate by the separation drive motor 203, which can quickly and accurately drive the two edge skin gripper mechanisms 100 to drive the edge skin to perform lateral displacement. Using the separation drive motor 203 as a power source makes it easy to accurately control it through the electrical control system. The speed, direction and other parameters of the motor can be adjusted according to actual needs, thereby flexibly controlling the lateral displacement speed and distance of the edge skin gripper mechanism 100 to adapt to the edge skin separation requirements under different sizes and working conditions.

[0049] Example 4:

[0050] like Figures 1-10 As shown, in the edge-feeding device of the present invention, the edge-feeding gripper mechanism 100 includes: a slide assembly 101 screwed onto a bidirectional lead screw 202, the slide assembly 101 being connected to a movable frame 102 slidably mounted on a transverse frame 201, two protrusions on the movable frame 102 being slidably mounted in the top and bottom transverse grooves of the transverse frame 201 respectively; sliding beams 103 are slidably mounted in the upper and lower front and rear sliding grooves at the front end of the movable frame 102, and the front ends of the two sliding beams 103 are connected to the gripper seat 100. 04 Connection: The lower jaw 105 is fixedly connected to the lower inner side of the jaw seat 104. The upper jaw 106 is slidably connected in the longitudinal sliding groove of the jaw seat 104. The middle part of the upper jaw 106 is slidably mounted on the vertical shaft in the longitudinal sliding groove. The outer side of the upper jaw 106 is connected to the clamping cylinder 107 installed on the outer side of the jaw seat 104. The rear ends of the two sliding beams 103 are connected by the limiting slide rod 108 slidably mounted in the limiting groove of the moving frame 102. The tension spring 109 is fixedly connected between the limiting slide rod 108 and the moving frame 102.

[0051] The working principle and technical effects of the above scheme are as follows:

[0052] In the edge-cutting device of the present invention, the slide assembly 101 is screwed onto the bidirectional lead screw 202. When the separation drive motor 203 drives the bidirectional lead screw 202 to rotate, due to the threaded engagement between the slide assembly 101 and the bidirectional lead screw 202, the slide assembly 101 will move laterally along the bidirectional lead screw 202 on the transverse frame 201. The slide assembly 101 is connected to the movable frame 102, and the two protrusions on the movable frame 102 are respectively slidably disposed in the top and bottom transverse grooves of the transverse frame 201, so that the movable frame 102 slides laterally on the transverse frame 201 together with the slide assembly 101, thereby driving the entire edge-cutting claw mechanism 100 to achieve lateral displacement; the outer side of the upper claw 106 is connected to the clamping cylinder 107 installed on the outer side of the claw seat 104; when the clamping cylinder 107 is activated, it will push The upper gripper 106 slides vertically along the vertical axis within the longitudinal groove of the gripper seat 104, thereby adjusting the distance between the upper gripper 106 and the lower gripper 105 and controlling their cooperation to grip edge skins of different sizes. The rear ends of the two sliding beams 103 are connected by limiting slide rods 108 that slide within the limiting grooves of the moving frame 102. A tension spring 109 is fixed between the limiting slide rod 108 and the moving frame 102. When the edge skin gripper mechanism 100 is impacted by an external force during the gripping or moving of the edge skin, the sliding beams 103 will slide within the front and rear sliding grooves, and the tension springs 109 will be stretched or compressed, providing a buffering effect. When the external force disappears, the elastic force of the tension springs 109 will reset the sliding beams 103, ensuring the normal operation of the edge skin gripper mechanism 100. In this invention, the bidirectional lead screw 202 drives the sliding block assembly 101 and the moving frame 102 to achieve precise lateral displacement of the edge skin gripper mechanism 100. The bidirectional lead screw 202 has high transmission accuracy and can accurately control the lateral movement distance of the edge skin gripper mechanism 100 according to requirements, ensuring that the edge skin can be accurately separated from the crystal rod. The moving frame 102, through the engagement of the protrusion with the transverse groove of the transverse frame 201, ensures the stability of the edge skin gripper mechanism 100 during lateral movement, reducing shaking and deviation. The clamping cylinder 107 drives the upper gripper 106 to engage with the lower gripper 105, providing sufficient clamping force to ensure that the edge skin will not fall off during gripping and separation. The design of the upper gripper 106 sliding along the vertical axis in the longitudinal groove ensures the straightness and accuracy of the gripping process, improving the reliability of gripping. The setting of the tension spring 109 and the limiting slide bar 108 gives the edge skin gripper mechanism 100 a buffer function. When subjected to external impact, the tension spring 109 can absorb energy, reducing damage to the edge gripper mechanism 100 itself and the edge. The elasticity of the tension spring 109 can automatically reset the sliding beam 103 after the external force disappears, ensuring that the edge gripper mechanism 100 can work continuously and stably, and improving the service life and working efficiency of the equipment.

[0053] Example 5:

[0054] like Figures 1-10 As shown, in the edge-cutting device of the present invention, the slide assembly 101 includes: a first seat plate 110 screwed onto the bidirectional lead screw 202, the first seat plate 110 sliding on the inner side of the transverse frame 201, the first seat plate 110 fixed to one end of the polygonal guide rod 111, the middle part of the polygonal guide rod 111 sliding in the transverse polygonal hole of the second seat plate 112, and the other end of the polygonal guide rod 111 fixed with an anti-loosening bolt 113 for locking the second seat plate 112 on the outside; the second seat plate 112 fixed to the movable frame 102, and the first seat plate 110 and the second seat plate 112 are connected by a compression spring 114 sleeved on the polygonal guide rod 111.

[0055] The working principle and technical effects of the above scheme are as follows:

[0056] In the edge-feeding device of the present invention, when the bidirectional lead screw 202 rotates, since the first seat plate 110 is screwed onto the bidirectional lead screw 202, the threaded engagement between the bidirectional lead screw 202 and the first seat plate 110 allows the bidirectional lead screw 202 to change its contact position with the first seat plate 110, thereby controlling the first seat plate 110 to slide on the inner side of the transverse frame 201. The first seat plate 110 is fixed to one end of the polygonal guide rod 111, and the second seat plate 112 is fitted onto the middle of the polygonal guide rod 111 through a transverse polygonal hole. The first seat plate 110 and the second seat plate 112... The two sides are connected by a compression spring 114 sleeved on the polygonal guide rod 111. When the bidirectional lead screw 202 controls the first seat plate 110 to move away from the transverse frame 201 on the inner side of the transverse frame 201, the first seat plate 110 will compress the spring 114 to generate elastic force. This elastic force will be transmitted to the second seat plate 112, causing the second seat plate 112 to move away from the transverse frame 201. Since the second seat plate 112 is fixed to the moving frame 102, and the moving frame 102 is connected to the edge skin gripper mechanism, the edge skin will eventually be separated from the crystal rod.

[0057] When the adsorption force between the edge skin and the crystal rod is large, the second base plate 112 cannot move directly with the first base plate 110 due to the large resistance. At this time, the first base plate 110 continues to move outward, which will compress the compression spring 114. When the compression spring 114 is compressed to the preset amplitude, the edge skin and the crystal rod still cannot be separated, and the first base plate 110 comes into contact with the pressure sensor set on the second base plate 112. The pressure sensor will sense the pressure change and transmit the signal to the alarm and the controller. After receiving the signal, the alarm will sound an alarm to remind the operator that the edge skin separation is abnormal; after receiving the signal, the controller will control the separation drive motor 203 to stop running to avoid applying excessive pressure.

[0058] In this invention, the compression spring 114 acts as a buffer. When the adhesion force between the edge skin and the crystal rod is large, the compression spring 114 can absorb some energy, avoiding excessive instantaneous impact force on the edge skin and crystal rod, reducing the risk of edge skin breakage and crystal rod damage, protecting the integrity of the edge skin and crystal rod, and improving product quality. The cooperation of the pressure sensor, alarm, and controller realizes intelligent early warning and protection functions. When the separation of the edge skin and crystal rod encounters difficulties, the system can promptly detect and issue an alarm, while stopping the operation of the separation drive motor 203 to prevent the pressure from continuously increasing and causing greater damage to the equipment and products, improving the safety and reliability of equipment operation, and reducing the probability of equipment failure and product scrap. The cooperative design of the polygonal guide rod 111 and the transverse polygonal hole ensures the stability of motion transmission between the first seat plate 110 and the second seat plate 112, preventing the guide rod from rotating during movement, so that the movement of the first seat plate 110 can be accurately transmitted to the second seat plate 112 through the compression spring 114, ensuring that the edge skin gripper mechanism can move laterally as expected, improving the accuracy and stability of the edge skin separation operation.

[0059] This invention can adapt to different adsorption forces between the edge skin and the crystal rod. When the adsorption force is small, the edge skin can be separated smoothly; when the adsorption force is large, corresponding protective measures can be automatically taken, which enhances the versatility and adaptability of the equipment, reduces manual intervention, and improves production efficiency.

[0060] Example 6:

[0061] like Figures 1-10 As shown, in the edge-cutting device of the present invention, the slide assembly 101 further includes: a gear 115, which is fixedly connected to the middle of the axle 116. The axle 116 is rotatably mounted on the second seat plate 112 through two upper and lower wheel seats. The end of the axle 116 is fixedly connected to a turntable 117. An off-center shaft 118 is fixedly connected to the eccentric part of the turntable 117. The off-center shaft 118 is rotatably connected to one end of the separation push rod 119. The other end of the separation push rod 119 is rotatably connected to the limiting slide rod 108. A rack 120 is installed in the groove on the front side of the polygonal guide rod 111. When the bidirectional screw 202 controls the first seat plate 110 to move towards the second seat plate 112 and compresses the compression spring 114 to a preset amplitude, the rack 120 contacts the gear 115 and meshes with the gear 115 to rotate.

[0062] The working principle and technical effects of the above scheme are as follows:

[0063] In the edge-feeding device of the present invention, in order to further enhance the separation effect between the edge and the crystal rod, when the bidirectional lead screw 202 controls the first seat plate 110 to move towards the second seat plate 112 and compresses the compression spring 114 to a preset amplitude, the rack 120 contacts and meshes with the gear 115 and the gear 115 rotates. The rotation of the gear 115 drives the wheel shaft 116 to rotate, and through the wheel shaft 116 drives the turntable 117 to rotate. When the turntable 117 rotates, it drives the offset shaft 118 to perform a circumferential motion. The offset shaft 118 drives one end of the separation push rod 119 to rotate. The other end of the separating push rod 119 reciprocates the pushing and pulling motion of the limiting slide rod 108, thereby controlling the limiting slide rod 108 to drive the two sliding beams 103 to slide in the upper and lower front and rear sliding grooves at the front end of the moving frame 102 in the front and back directions. This drives the gripper seat 104 and the upper gripper 106 and lower gripper 105 to move in the front and back directions. Thus, the upper gripper 106 and lower gripper 105 control the edge skin to slide on the cutting surface of the crystal rod when it cannot move away from the crystal rod. After the contact area between the two becomes smaller, they are easier to separate.

[0064] In this invention, when the adsorption force between the edge skin and the crystal rod is large, and it is difficult to separate the edge skin from the crystal rod by relying solely on the lateral movement of the edge skin gripper mechanism driven by the bidirectional lead screw 202, this solution provides additional separation power. When the compression spring 114 is compressed to a preset amplitude, the rack 120 and gear 115 mesh, driving the relevant components to move, causing the edge skin to slide on the cutting surface with the crystal rod. This sliding can break the adsorption force between the edge skin and the crystal rod, effectively overcoming the adsorption resistance, making it easier for the edge skin to separate from the crystal rod, and improving the success rate of edge skin separation. By controlling the upper gripper 106 and lower gripper 105 to drive the edge skin to move back and forth on the cutting surface, the contact area between the edge skin and the crystal rod is reduced. According to the principles of friction and adsorption, the reduction of the contact area will reduce the adsorption and friction between the two, thereby further reducing the difficulty of edge skin separation and enhancing the edge skin separation effect. In actual production, the adsorption force between the edge skin and the crystal rod may vary due to various factors (such as cutting process, crystal rod surface characteristics, etc.). This invention enables the edge-skin feeding device to automatically adjust the separation method according to the specific adsorption conditions. When the adsorption force is low, separation is mainly achieved by the lateral drive of the bidirectional lead screw 202; when the adsorption force is high, the rack and pinion mechanism is triggered to provide additional separation action, allowing the equipment to adapt to different working conditions and improving its versatility and applicability. Compared with the separation method of simply increasing the lateral tension, this separation method, which allows the edge skin to slide on the cutting surface, is gentler, avoiding the risk of edge skin breakage or crystal rod damage caused by excessive lateral tension, protecting product quality, reducing scrap rate, and improving production efficiency.

[0065] The polygonal guide rod 111 is rotatably connected to the adjusting screw 121 in the front groove. The adjusting screw 121 is threadedly connected to the rack 120 that slides in the front groove to control the rack 120 to slide in the front groove. The inner end of the anti-loosening bolt 113 abuts against the adjusting screw 121.

[0066] The working principle and technical effects of the above scheme are as follows:

[0067] In the edge-feeding device of the present invention, a control screw 121 is rotatably connected to the front groove of the polygonal guide rod 111. A rack 120 is slidably disposed in the front groove and threadedly connected to the control screw 121. When the control screw 121 is rotated, the rack 120 slides within the front groove due to the threaded transmission. The inner end of the anti-loosening bolt 113 abuts against the control screw 121, which can limit the control screw 121 to a certain extent, ensuring it works in the appropriate position. The magnitude of the adsorption force between the edge-feed and the crystal rod varies depending on the crystal rod material, cutting process, and other factors. By adjusting the position of the rack 120, the timing of contact between the rack 120 and the gear 115 under different pressures (i.e., different compression amplitudes of the compression spring 114) can be changed. When the adsorption force between the edge-feed and the crystal rod is small, the position of the rack 120 can be adjusted so that it contacts the gear 115 when the compression spring 114 has a small compression amplitude, allowing the additional separation auxiliary action (the back-and-forth movement of the edge-feed gripper mechanism) to intervene earlier, thereby improving the separation efficiency. When the adsorption force is strong, the rack 120 is adjusted so that it only contacts the gear 115 when the compression spring 114 is at its maximum compression amplitude. This avoids premature triggering of the auxiliary action, which would prevent sufficient separation force from being generated. It ensures that the separation effect is enhanced by the back-and-forth movement of the edge gripper mechanism at the appropriate time. This adjustment method allows operators to make precise adjustments based on different situations in actual production. For example, for certain special-sized crystal rods or edge strips, precise adjustment of the rack 120 position allows the edge strip to slide back and forth under the most suitable pressure and timing, further breaking the adsorption force between the edge strip and the crystal rod, thereby achieving more precise separation operation and improving the separation quality and success rate of the product. If the adhesion force between the edge skin and the crystal rod is small, the rack 120 contacts the gear 115 when the compression spring 114 is compressed to a small extent. This allows the edge skin gripper mechanism to initiate forward and backward movement to assist separation in advance. This avoids the bidirectional lead screw 202 continuously applying excessive lateral force, reducing the stress on various components of the equipment (such as the bidirectional lead screw and slide assembly), lowering the wear and failure risk of the equipment, and extending its service life. Appropriate rack 120 position adjustment can make the force on the edge skin more reasonable during separation. When the adhesion force between the edge skin and the crystal rod is large, the forward and backward movement of the edge skin gripper mechanism is triggered under appropriate pressure, avoiding edge skin breakage or crystal rod surface damage due to excessive lateral tension. This ensures the quality of the edge skin and crystal rod and reduces the scrap rate.

[0068] Example 7:

[0069] like Figures 1-10 As shown, the dual-station squaring equipment includes the aforementioned edge-cutting device, and further includes: a base, on which a loading / unloading mechanism for loading or unloading monocrystalline silicon rods is installed, the loading / unloading mechanism being located between two stations on the base; each of the two stations on the base is equipped with a positioning mechanism for positioning and fixing the monocrystalline silicon rods and a cutting mechanism for cutting the monocrystalline silicon rods from round rods into square rods; the edge-cutting device is installed on the base and is used to control the separation of the edge-cutting device from the square rods after the monocrystalline silicon rods are cut. In a dual-station squaring machine, a sensing device is installed on the contact surface between the lower gripper 105 and the edge skin. When the edge skin is clamped by the upper gripper 106 and the lower gripper 105, if the sensing device does not detect the edge skin, it sends a signal to the alarm, activates the alarm program, illuminates the clamping indicator light, and suspends the ongoing action at that station and subsequent actions. Manual inspection is then performed to prevent mechanical damage and product loss until the edge skin and debris in the station are completely removed. After carefully checking the feed head position and other relevant parameters, the machine can be manually removed to resume normal operation. The sensing device can be a pressure sensor.

[0070] The working principle and technical effects of the above scheme are as follows:

[0071] The dual-station squaring equipment has a loading and unloading mechanism mounted on its base, located between two stations. This mechanism is responsible for transporting the monocrystalline silicon rod to the corresponding station for processing and removing the processed square rod from the station. Positioning mechanisms at the two stations on the base position and fix the monocrystalline silicon rod, ensuring accurate positioning during the cutting process. Then, the cutting mechanism cuts the monocrystalline silicon rod from a round rod into a square rod, generating edge trimmings in the process. An edge trimming device mounted on the base controls the separation of the edge trimmings from the square rod after cutting. The edge trimming device clamps the edge trimmings using upper jaw 106 and lower jaw 105, thus separating the edge trimmings from the square rod. A sensor is installed on the contact surface between the lower jaw 105 and the edge trimmings. When the edge trimmings are clamped by the upper jaw 106 and lower jaw 105, if the edge trimmings are properly clamped, the sensor will detect a certain pressure signal. However, if the sensor does not detect the edge trimmings, i.e., no corresponding pressure signal is detected, the sensor will transmit this signal to an alarm. Upon receiving a signal, the alarm system activates its alarm procedure, illuminating the clamping indicator light. Simultaneously, the system pauses the ongoing operation at that station and subsequent actions, awaiting manual inspection and handling. Continuing with edge separation or other operations if the edge material is not properly clamped may subject the mechanical structure of the edge material feeding device to abnormal forces, potentially causing equipment damage. The sensor system can promptly detect instances of loose edge material, pausing the station's operation to prevent continued operation under abnormal conditions, reducing the risk of equipment damage and extending its lifespan. Performing separation operations with loose edge material may result in incomplete separation or even damage to the square bar, affecting product quality. Timely detection and pausing prevents this, ensuring product quality and integrity and minimizing losses. The sensor system automatically detects whether the edge material is clamped and triggers an alarm upon detection of an abnormality, eliminating the need for constant manual monitoring and enhancing the equipment's intelligence. This allows operators to be promptly informed of any abnormalities and take appropriate action. The system automatically pauses the operation at that station and subsequent actions upon detecting loose edge material, preventing erroneous continuation. After manually inspecting and removing the edge skin and debris from the workstation, and carefully checking the relevant parameters such as the position of the feed head, the manual edge skin removal function can be used to restore the normal operation of the squaring machine. This realizes automated control and flexible recovery of equipment operation, and improves production efficiency.
