[0001] The utility model relates to the technical field of hard and brittle material processing equipment, and specifically provides a grinding machine production line. Background Art

[0002] Equipment for processing hard and brittle materials usually includes cutting machines, squaring machines, grinders and slicers. Taking the workpiece of hard and brittle material as silicon rod as an example, the cutting machine is mainly used to cut longer silicon rods into shorter silicon rods (such as silicon rods with a circular cross-section, referred to as round rods) by methods such as wire cutting, the squarer is mainly used to cut round rods into silicon rods with a rectangular cross-section (such as a square) by methods such as wire cutting (referred to as square rods, if the square rods at this stage have not been ground, they can usually be called rough rods), the grinder is mainly used to make the surface accuracy of the rough rod meet the standard through grinding operations (such as the square rods at this stage meet the surface accuracy after grinding, and they can usually be called finished rods), and the slicer is mainly used to obtain thin silicon wafers for use from the finished rods through methods such as multi-wire cutting (wire mesh cutting).

[0003] Take the grinding operation as an example. The grinding operation of the existing grinding machine is concentrated near the grinding station. Each grinding operation is a stand-alone operation for a single silicon rod. Since each grinding operation usually includes multiple operation steps and includes manual intervention of operators on site (such as in the loading / unloading link), this processing method often has the following problems: the operation of the grinding machine requires high professionalism and proficiency of the operator. Once the operator makes a mistake, it may cause grinding anomalies of varying degrees and lead to waste of raw materials.

On the one hand, each grinding operation usually includes multiple operation steps and includes manual intervention of the operator on site (such as in the loading / unloading link). Such a processing method often has the following problems: the operation of the grinder requires high professionalism and proficiency of the operator. Once the operator makes a mistake, it may cause grinding anomalies of varying degrees and thus waste raw materials.

[0032] With such a configuration, it is possible to realize the overall rotation of the clamping jaw assembly through the second adjustment assembly, thereby making it possible to adjust the axis of the workpiece clamped by the clamping jaw assembly.

[0033] It is understandable that those skilled in the art can determine the structure, number, and specific manner of relative motion between the first / second clamping jaw assembly according to actual needs. For example, the manner in which the first / second clamping jaw assembly produces relative motion can be that one of the clamping jaw assemblies moves or both of the clamping jaw assemblies move.

[0034] In addition, in addition to meeting the basic clamping requirements, the posture of the clamped silicon rod (such as whether it is centered, tilted, etc.) can be adjusted through other forms of movement or motion.

[0035] For the above-mentioned grinding machine production line, in a possible implementation manner, the clamping assembly includes a clamping base, the first clamping assembly and the second clamping assembly are arranged on the clamping base, and the second adjustment assembly can drive the clamping base, the first clamping assembly and the second clamping assembly to rotate.

In this way, the fixed jaw assembly can be fixedly arranged on the transport mechanism or movably arranged on the transport mechanism by switching the switching assembly, such as a movement similar to the movement form and direction of the adjustment jaw assembly or a movement that is partially different from or relatively independent of the adjustment jaw assembly.

[0056] It is understandable that those skilled in the art can determine the structural form of the switching component and the state switching mode under the driving of the switching driving component and the specific implementation mode of establishing / releasing the constraint with the fixed jaw assembly according to the actual situation. For example, the switching component can be a plate-like structure, a rod-like structure, etc., which can change its state through movement modes such as extension and rotation under the driving of the switching driving component.

[0057] For the above-mentioned grinding machine production line, in a possible implementation manner, the switching component is a clamping structure, and the switching driving component can drive the clamping structure to extend and cause the clamping jaw to move laterally to establish a constraint between the transmission structure and the fixed clamping jaw assembly.

[0062] With such a configuration, it is possible to change the local position of the workpiece by vertical fine adjustment on the side of the adjusting jaw assembly, and thereby adjust the posture to be processed so that its accuracy meets the grinding standard.

[0063] For the above-mentioned grinding machine production line, in a possible implementation manner, the first adjustment assembly includes a first eccentric structure, and the first adjustment driving component drives the first jaw and the second jaw of the adjustment jaw assembly to move in a vertical direction through the first eccentric structure.

[0064] Through such a structure, a possible implementation method for adjusting the first / second clamping jaw of the clamping jaw assembly to achieve its lifting movement is provided.

[0180] In addition, in order to better illustrate the present invention, many specific details are given in the specific embodiments below. Those skilled in the art should understand that the present invention can also be implemented without certain specific details. In some examples, the grinding control logic of the grinding machine, which is well known to those skilled in the art, is not described in detail in order to highlight the main purpose of the present invention.

[0181] Refer to the following Figures 1 to 29 At least a part of the present invention is described herein.

[0182] In a possible implementation, the utility model provides a grinding machine production line capable of realizing the automated production of multiple grinding machines. The grinding machine production line 100 mainly includes a production line body, such as the production line body may include (but not limited to) a control terminal configured at the work site, a collection terminal (such as visual signals, sound signals, etc.) that can collect the grinding operation at the site, a central control terminal that can analyze and control the grinding operation at the site, and a reminder terminal that can send signals such as voice / alarm when necessary. The production line body is configured with multiple single machines (grinding components). Based on this, it is expected that multiple single machines can simultaneously grind a group of silicon rods (grinded square rods) to be processed (a group containing multiple silicon rods) or select a part of them to grind a corresponding number of silicon rod groups. If multiple single machines are configured in a removable manner in the grinding machine production line, the scale of the grinding machine production line can be flexibly adjusted, and the single machine can be replaced or repaired after removal. In addition, the structural form, grinding operation method and the method of configuring the multiple single machines in the production line body can be the same or different. For example, the main body of the production line has multiple grinding stations, each of which is equipped with a single machine (if required, multiple machines can also be configured). The structural form and processing accuracy of the single machines corresponding to different grinding stations can be the same or different. For example, one or several of the single machines are mainly used to process silicon rods with more stringent grinding requirements, so the single machine corresponding to the corresponding station needs to have higher processing accuracy.

[0183] In a possible embodiment, in the grinding machine production line of the utility model, corresponding to any one grinding unit (a unit capable of completing a complete grinding operation), it mainly includes a grinding component 1 as a single machine, a transfer mechanism 2 shared by multiple single machines, and a loading and unloading component shared by multiple single machines, wherein the transfer mechanism 2 mainly includes a gantry component 21, a moving component 22, and a clamping component 23. In this example, the gantry component mainly includes a basic support part 211 and a gantry 212 arranged on the basic support part. The moving component mainly includes a transverse moving component 221 capable of moving the clamping component 23 along the length direction of the gantry and a longitudinal moving component 222 capable of moving the clamping component 23 along the vertical direction. The clamping component 23 can clamp the silicon rod and the clamping component 23 and the clamping component are arranged on the moving component so as to realize the movement of the silicon rod along different dimensions with the help of the moving component. Among them, the loading and unloading components mainly include a loading component 31 and a unloading component 32. The silicon rods that have completed squaring (square rods formed after removing the edge skin) enter the main body of the production line through the loading component, and the silicon rods that have completed grinding (usually including grinding of the sides and edges) leave the main body of the grinder production line through the unloading component.

[0184] For example, for the grinding operation of any grinding unit, when the silicon rod is clamped in the clamping jaw assembly (the clamping jaw assembly holds the silicon rod), the moving assembly can be used to realize the transfer of the rough rod from the loading assembly to the grinding assembly corresponding to the grinding unit and the transfer of the finished rod from the grinding assembly to the unloading assembly.

[0185] In this example, the main body of the production line has four grinding stations 101 (such as four stations in this example) arranged along the length direction of the gantry, each grinding station is provided with a grinding assembly 1 as a single machine, and the manipulator including the moving assembly 22 and the clamping assembly 23 in the transfer mechanism 2 (the part of the moving assembly except the partial structure of the lateral moving assembly 221) can move along the gantry, and any grinding assembly and the transfer mechanism constitute a fully functional grinding unit. Obviously, the number of grinding stations and the relative position relationship between each station are only a specific form of the main body of the production line. Obviously, those skilled in the art can flexibly determine the scale and specific composition of the main body of the production line according to actual needs. For example, it can include but is not limited to: the walking path of the gantry is roughly an L-shaped structure, and a transfer mechanism is respectively configured in the horizontal area and the vertical area of ​​the L-shaped structure; the gantry includes multiple parallel ones, and a transfer mechanism is configured for each gantry; corresponding to a certain grinding station, another gantry extends in a direction perpendicular to the gantry, and multiple grinding stations can be set along the walking direction of the other gantry; etc.

[0186] In a possible implementation, multiple stand-alone machines share one loading assembly and one unloading assembly, and similar loading and unloading control logic is used for the stand-alone machines. Obviously, the structure of the loading / unloading assembly can also be adjusted according to actual needs, such as but not limited to: configuring multiple loading assemblies and unloading assemblies for multiple stand-alone machines, such as configuring one loading assembly and unloading assembly for one or more stand-alone machines according to the orientation, priority, product model, and the properties of the silicon rods to be ground (such as the particularity or importance of a batch of products, etc.), for example, on the basis of configuring one loading assembly and unloading assembly for multiple stand-alone machines along the length direction of the gantry, additionally configuring a separate loading assembly and unloading assembly for a certain stand-alone machine; multiple stand-alone machines share one loading assembly and one unloading assembly, but configuring a separate loading / unloading control logic for one or several stand-alone machines (such as also according to the aforementioned orientation, priority, product model, and the properties of the silicon rods to be ground, etc.).

[0187] Still taking the example of multiple single machines sharing one group of loading components and one group of unloading components, the transfer mechanism of the grinding machine production line is mainly used to realize the transfer of silicon rods to be ground and the ground silicon rods between the loading component, the grinding component and the unloading component, as well as to perform corresponding docking, adjustment and other work at the loading station corresponding to the loading component, the unloading station corresponding to the unloading component and the grinding station corresponding to the grinding component, such as transferring the silicon rods to be ground between the loading component and the grinding component (loading operation), transferring the ground silicon rods between the grinding component and the unloading component (unloading operation), performing corresponding docking operations with the upper / lowering components at the loading / unloading stations (such as alignment of the clamping position with the upper / lowering components, clamping / loosening of the silicon rods in the clamping position, etc.), and performing connection operations such as picking up and discharging materials at the upper / lowering components and the area between the two.

[0188] In this example, the manipulator including the gripper assembly in the transfer mechanism can walk on the gantry along the direction between the loading assembly, the unloading assembly and the different grinding stations, and the manipulator and the gantry cooperate to realize the movement requirements of the manipulator walking between the loading assembly and the unloading assembly (such as in the length direction corresponding to the grinding machine production line, which can be called the length direction) and along the width direction of the gantry. And the movement of the gripper assembly in the vertical direction realized by the manipulator realizes the movement requirements of the silicon rod approaching / moving away from the grinding station in the vertical direction. In practice, the number of corresponding single grinders can be calculated according to the logical beat of the group control system of the grinding machine production line, so as to realize the grinding operation and loading and unloading operation of the silicon rod for the single grinder / grinding machine production line by the walking of the manipulator on the gantry and the lifting and lowering movement of the silicon rod realized by the manipulator. For example, the group control system can match the appropriate single machine for the silicon rod or silicon rod group that needs to be ground currently and give a specific control strategy for the grinding operation in combination with the number of silicon rods to be ground, the equipment status of the single grinder, the status of the manipulator, etc.

[0189] Based on this, the working mode of the grinding machine production line is roughly as follows: the manipulator, in accordance with the control instructions of the group control system, starts the silicon rod to be ground from the loading station corresponding to the loading assembly, and through the coordination between the manipulator's movement along the length direction and the width direction of the gantry, transports the silicon rod to a preset target position that can be connected with the single grinder of the target grinding station, such as the target position is usually above the grinding assembly in the corresponding grinding station. When the silicon rod is delivered to the target position, the group control system reconfirms the status information of the single grinder corresponding to the current delivery operation based on equipment management information, such as status information including but not limited to information such as in operation, debugging, maintenance, troubleshooting, and standby. After the single grinder completes the grinding operation of the silicon rod including the sides and edges, the manipulator first lifts the silicon rod to the top of the grinding assembly, and then moves the ground square rod to the unloading station corresponding to the unloading assembly through the unloading walking path.

[0190] It can be seen that in the grinding production line of the utility model, the functional area mainly includes a loading station corresponding to the loading assembly, a grinding area corresponding to multiple single machines (including multiple grinding stations), and a unloading station corresponding to the unloading assembly. Based on this, with the help of the transfer mechanism, the switching of silicon rods between different grinding stations and the accurate docking between the silicon rods and any grinding station can be realized.

[0191] [Cantilever crane assembly, sampling assembly, blow-drying assembly, abnormal workpiece collection assembly]

[0192] In a possible implementation, the production line body is equipped with a cantilever hanging assembly 4, such as the cantilever hanging assembly is arranged at a position of the production line body corresponding to the loading / unloading station. Based on this, the silicon rods that have been squared can be delivered to the loading station of the loading assembly with the help of the cantilever hanging assembly 4. If the loading / unloading assembly cannot be docked with the grinding machine production line, the loading / unloading can be realized by manual operation with the help of the cantilever hanging assembly.

[0193] Among them, the unloading component can be directly connected to the downstream process end of a grinder such as a slicer that can slice silicon rods. For example, the structural arrangement of the slicer can also be a slicing production line including multiple slicers. Under normal circumstances, a degumming workshop is set up on the downstream side of the slicer. The degumming workshop is mainly used to degumming silicon rods (silicon wafer groups) that have been bonded to the crystal support and have completed the slicing operation. For example, the cart carrying the silicon rods can be manually transferred to the degumming workshop or the silicon rods can be automatically moved through ACV / RGV.

[0194] In a possible implementation, the production line body is equipped with a sampling inspection component 5, such as a sampling inspection component arranged in an area where the production line body can be connected with the unloading station. Based on this, the sampling inspection component can be used to perform sampling inspections on the finished square bars after grinding, thereby ensuring the reliability of the grinding operation.

[0195] In a possible embodiment, the sampling inspection component 5 mainly includes a sampling inspection platform bracket 51, and a first support seat 52 (driving shaft support seat) is provided at the front end of the sampling inspection platform bracket 51 (the short end close to the unloading platform assembly), and a driving shaft is installed in the driving shaft support seat, and two driving synchronous wheels 53 are provided on the driving shaft, and one end of the driving shaft is connected to a sampling inspection drive motor 54. A second support seat 55 (driven shaft support seat) is provided at the rear end of the sampling inspection platform bracket 51, and a driven shaft is installed in the driven shaft support seat, and two driven synchronous wheels 56 are provided on the driven shaft, and the driving synchronous wheels and the driven synchronous wheels are connected by a synchronous belt 57. A guide groove 58 is provided at the end of the driven shaft support seat, and an adjustment screw 59 is provided in the guide groove. The adjustment screw passes through the driven shaft support seat and is screwed with the driven shaft. The position of the driven shaft support seat can be adjusted by moving the adjustment screw in the guide groove, thereby tightening the synchronous belt between the driving shaft and the driven shaft.

[0196] Obviously, the above structure is only a specific structural form that can realize the transmission of rod materials when sampling silicon rods. Technical personnel in this field can flexibly adjust the relevant drive transmission adjustment structure according to actual needs. For example, the matching of the synchronous belt and the synchronous wheel can be adjusted to the matching of the belt and the pulley, the matching of the guide rail and the lead screw, the matching of the guide rail and the gear / rack, the matching of the cylinder and the guide rail, etc.

[0197] Among them, the sampling inspection component is connected with the unloading component. When the pre-set sampling inspection conditions are met, the clamping claw component first clamps the finished square rod after grinding to the unloading table of the unloading component. By reversing the unloading table driving component, the finished square rod that has arrived at the unloading table can be transferred to the sampling inspection table, based on which the current finished silicon rod can be sampled. After the sampling inspection is completed, assuming that the finished square rod is qualified, the sampling inspection table driving component can be rotated forward to transfer the finished square rod from the sampling inspection table to the unloading table of the unloading component, or the finished square rod can be directly transferred to the unloading conveyor line of the unloading component.

[0198] In a possible implementation, the main body of the production line is provided with a blow-drying assembly 6, such as a blow-drying assembly disposed between the unloading platform assembly 321 and the unloading conveyor line 322 of the unloading assembly 31. Based on this, when it is detected that a finished square rod is transferred from the unloading platform to the unloading conveyor line, the unloading speed of the unloading conveyor line is reduced, so that the finished silicon rod slowly passes through the blow-drying assembly, thereby drying the residual water stains on the surface of the finished square rod.

[0199] In a possible embodiment, the drying assembly 6 mainly includes a drying base, and the drying base includes a support frame 61, and a mounting portion (such as a mounting plate 62, etc.) is provided on the support frame 61, and the mounting plate can be connected to the position of the unloading assembly corresponding to the unloading platform assembly and the unloading conveyor line. A water retaining assembly is provided on the support frame, and the water retaining assembly includes a first water retaining portion 631 (such as a water retaining box, etc.) and a second water retaining portion 632 that are relatively arranged, and the first water retaining portion and the second water retaining portion form a space allowing the finished silicon rod to pass through, and a water retaining brush 64 is provided between the first water retaining portion and the second water retaining portion at a position close to the top. The support frame 61 is provided with a wind knife assembly 65 in the space enclosed by the first water retaining portion and the second water retaining portion, and the wind knife assembly can blow air to the surface of the finished silicon rod when the finished silicon rod passes through the space formed by the first water retaining portion and the second water retaining portion.

[0200] For example, in order to ensure that the surface of the finished silicon rod can be fully dried, wind knife assemblies can be provided at the bottom, sides and top of the support frame. For example, if the support frame is a roughly rectangular structure, a wind knife assembly is provided near the bottom / side of the support frame corresponding to, close to or parallel to the edge, and a wind knife assembly is provided at a position near the middle of the top of the support (water-blocking brush) to ensure that the finished square rods can be dried in all directions.

[0201] In a possible implementation, the drying assembly 6 includes an air inlet assembly 66 and an air path assembly (not shown), and the gas can reach the air knife assembly from the air inlet assembly through the air path assembly to dry the surface of the finished silicon rod. In this example, the air inlet assembly is arranged below the water retaining assembly (outside the bottom), and the air knife assemblies are arranged in four directions of the top, bottom, left and right inside the drying assembly, which can ensure that the finished square rod is dried in all directions.

[0202] Obviously, the above structure is only a specific structural form when the silicon rod is dried for the second time. Technical personnel in this field can flexibly adjust the relevant structure according to actual needs, such as: replacing the wind knife assembly with other structural forms such as a nozzle; integrating the water retaining box, the mounting plate and the support frame; etc.

[0203] In a possible implementation, the production line body is equipped with an abnormal workpiece collection assembly 7, such as an abnormal workpiece collection assembly also arranged in an area where the production line body can be connected with the unloading station. Based on this, the silicon rods sampled by the sampling assembly or directly determined as unqualified can be collected (and transported), thereby ensuring the sustainability of the grinding operation.

[0204] In a possible implementation, the abnormal workpiece collection assembly 7 mainly includes an abnormal workpiece collection base and an abnormal workpiece collection trolley 71, and the abnormal workpiece collection base includes a positioning assembly and a guide wheel assembly. The positioning assembly includes a photoelectric switch 72, a limit switch 73, and a rotary cylinder 74, etc., wherein the photoelectric switch 72 can detect whether there is material (silicon rod) on the collection position 711 of the abnormal workpiece collection trolley, the limit switch 73 is used to detect whether the abnormal workpiece collection trolley is pushed into place, and the rotary cylinder 74 is used to hook the abnormal workpiece collection trolley when the abnormal workpiece collection trolley is pushed into place, so as to prevent the abnormal workpiece collection trolley from moving relative to the abnormal workpiece collection base after positioning.

[0205] In one possible embodiment, the abnormal workpiece collecting base includes a guide wheel assembly 75, and the abnormal workpiece collecting trolley enters the abnormal workpiece collecting base along the guide wheel assembly and is pushed toward the positioning assembly. When the front end of the abnormal workpiece collecting trolley contacts the limit switch 73, the rotary cylinder hooks the abnormal workpiece collecting trolley according to the feedback signal of the limit switch to prevent the abnormal workpiece collecting trolley from moving again. In this way, the positioning of the abnormal workpiece collecting trolley is completed.

[0206] Obviously, the above-mentioned abnormal workpiece collection component is only an exemplary description, and those skilled in the art can adopt a suitable structure to collect abnormal silicon rods according to actual needs to ensure the sustainability of the grinding machine production line.

[0207] During the operation of the grinding machine production line, when abnormal silicon rods appear at any stage, the abnormal silicon rods can be clamped to the empty collection position of the abnormal workpiece collection trolley through the transfer mechanism. If the grinding machine production line has an abnormal rod detection function, when an abnormal rod is detected, the abnormal rod can be directly clamped to the abnormal rod collection component through the clamping claw assembly. The abnormal workpiece collection component 7 determines whether there is material on each collection position of the abnormal workpiece collection trolley based on the feedback signal of the photoelectric switch. When the abnormal workpiece collection trolley is full of material (silicon rods are collected on each collection position), the full abnormal workpiece collection trolley can be removed.

[0208] It can be seen that in this example, multiple single machines of the grinding machine production line share a set of loading components, a set of unloading components, and a set of sampling components, which improves the utilization rate of the loading and unloading components, saves the overall equipment floor space of the grinding machine production line, and reduces the cost of the production line. It can be understood that the way in which the aforementioned loading and unloading components, sampling components, and abnormal workpiece collection components constitute the grinding machine production line is only an exemplary description. Those skilled in the art can flexibly arrange the loading / unloading stations, sampling stations, and abnormal workpiece collection stations corresponding to the loading and unloading components, sampling components, and abnormal workpiece collection components according to actual needs. For example, the installation position of the corresponding functional components can be flexibly adjusted according to the production needs of different sites. Taking the aforementioned gantry's walking path as an example, which is roughly an L-shaped structure, it can include but is not limited to: adding loading / unloading stations, sampling stations, and / or abnormal workpiece collection stations at the junction of the L-shaped structure; integrating the sampling stations and abnormal workpiece collection stations to a certain extent; etc.

[0209]

Gantry assembly

[0210] In a possible implementation, the gantry assembly 21 includes a basic support portion 211 and a gantry 212. In this example, the basic support portion 211 includes a gantry column and a gantry frame arranged on the gantry column. The gantry 212 includes a main end and a secondary end arranged in parallel on the gantry frame. A reinforcing structure such as a connecting rib 213 is also arranged between the main end and the secondary end to improve the integrity of the gantry assembly and thus make the structure more stable. The gantry assembly mainly plays a supporting role and provides an installation / movement environment for the mobile assembly.

[0211] [Horizontal movement component of mobile component]

[0212] In a possible implementation, the lateral movement assembly 221 includes a lateral movement drive component, a lateral movement transmission mechanism, and a lateral movement guide component. As in this example, the lateral movement drive component is a lateral movement drive motor 2211, and the lateral movement transmission mechanism is a lateral movement rack and pinion mechanism 2212. One of the two gantries (the main end) is equipped with a drive motor (as well as a lateral movement transmission mechanism, a lateral movement guide mechanism, etc.) and is therefore called the main end, while the other is not equipped with a drive mechanism and is therefore called the secondary end. As in this example, the lateral movement transmission mechanism is a rack and pinion mechanism. Obviously, other transmission components / transmission mechanisms such as a screw nut mechanism, a belt mechanism, and a chain mechanism can also be used according to actual needs.

[0213] The lateral moving assembly 221 can realize the lateral movement of the clamping assembly 23 along the length direction of the gantry, and also plays a supporting role for the longitudinal moving assembly. Since structures such as the clamping assembly and the silicon rod are also arranged on the lateral moving assembly, the weight borne when playing a supporting role is relatively large. In order to ensure the reliability of the supporting role, in a possible embodiment, the lateral moving guide assembly includes a lateral moving hard rail 22131, a lateral moving guide wheel 22132 capable of walking on the lateral moving hard rail 22131, and a lateral moving load-bearing wheel 22133 that mainly bears its load. In the process of the lateral moving guide assembly realizing its guiding role, the aforementioned weight is mainly borne by the load-bearing wheel. For example, according to actual needs, other guide rail structures such as guide rails, optical axes, etc. that can also ensure transmission accuracy can be used to replace the lateral moving hard rail.

[0214] In a possible implementation, the moving assembly 22 includes a slide 223, the clamping assembly 23 is arranged on the slide, and the lateral movement driving motor drives the slide to move on the lateral movement hard rail through the lateral movement gear rack mechanism, so that the slide drives the clamping assembly to move along the gantry. In this way, the slide and the clamping assembly arranged on the slide can be accurately moved along the gantry through the servo control of the lateral movement driving motor. For example, limit detection switches can be respectively arranged on both sides of the slide along its lateral movement direction to ensure that the slide can accurately move within its effective stroke.

[0215] In a possible implementation, the lateral movement guide wheel 22132 of the lateral movement assembly 221 is arranged on a side (lower side) close to the lateral movement hard rail 22131, and the lateral movement load-bearing wheel 22133 is arranged on a side (upper side) close to the slide 223, so that the main pressure-bearing effect can be shared by the load-bearing wheel. Compared with the method of pressing the entire weight on the slider in the guide rail slider assembly, such a structure can obtain better pressure-bearing reliability.

[0216] In a possible embodiment, the slide 223 is provided with a transverse movement guide assembly installation part at the end near the gantry, and the aforementioned transverse movement guide wheel 22132 and transverse movement bearing wheel 22133 are both arranged on the transverse movement guide assembly installation part. For example, the transverse movement guide wheel 22132 includes two wheels riding on the transverse movement hard rail 22131, one of which is used as a reference wheel and the other is used as an adjustment wheel. It is adapted to the movement direction of the transverse movement assembly, such as the rolling direction of the transverse movement bearing wheel 22133 is consistent with the lateral movement direction (the length direction of the gantry), that is, the axis (vertical direction) of the transverse movement guide wheel 22132 is approximately perpendicular to the axis (horizontal direction) of the transverse movement bearing wheel 22133. In order to better ensure the pressure-bearing reliability, a plurality of transverse movement bearing wheels 22133 can be arranged on the transverse movement guide assembly installation part. Exemplarily, one or a group (such as a pair of equal) of transverse movement bearing wheels 22133 are respectively arranged at the positions near the four corners of the transverse movement guide assembly installation part. Taking the case where the lateral moving load-bearing wheels 22133 include a pair as an example, the pair of lateral moving load-bearing wheels 22133 can be arranged along the width direction or the length direction of the gantry.

[0217] [Moving components of vertical moving components]

[0218] In a possible embodiment, the longitudinal moving assembly 222 includes a longitudinal moving slide 2221 (located between the main end and the secondary end and slidably connected to the slide), a longitudinal moving driving component and a longitudinal moving transmission mechanism. In this example, the longitudinal moving driving component is a longitudinal moving driving motor 2222, and the longitudinal moving transmission mechanism is a longitudinal moving gear rack mechanism 2223. For example, the longitudinal moving driving component can also be a motor, a motor with a reducer and other driving parts / driving mechanisms; the longitudinal moving transmission mechanism can also be a sprocket chain mechanism, a screw nut mechanism, etc. For example, the longitudinal moving gear rack mechanism includes a longitudinal moving gear connected to the longitudinal moving driving motor and a longitudinal moving rack arranged on the longitudinal moving slide. The longitudinal moving driving motor is arranged on the slide and thus makes the slide and the longitudinal moving slide produce relative movement in the vertical direction. Under the limitation of the aforementioned lateral moving assembly, the slide cannot produce movement in the vertical direction, so the longitudinal moving slide can produce movement in the vertical direction. Based on this, the longitudinal moving driving motor can drive the longitudinal moving slide and the clamping claw assembly arranged thereon to produce movement in the vertical direction through the longitudinal moving gear rack mechanism. In this way, the slide can be accurately moved in the longitudinal direction by servo control of the longitudinal drive motor. The power from the longitudinal drive motor is transmitted by the meshing of the longitudinal gear / rack, and such a structure can effectively save the layout space of the longitudinal movement components including the longitudinal gear rack mechanism.

[0219] In a possible embodiment, a longitudinal moving guide assembly is also provided on the longitudinal moving slide 2221, such as the longitudinal moving guide assembly includes a longitudinal moving linear guide 2224, to ensure the stability of the longitudinal moving process. For example, if the cross-section of the longitudinal moving slide is roughly rectangular, a longitudinal moving linear guide is respectively provided near each edge of the rectangle, so there are four longitudinal moving linear guides in total, so that the slide can obtain better stability when moving relative to the longitudinal moving slide along the longitudinal moving direction. Among them, the four longitudinal moving linear guides are located on three of the surfaces of the longitudinal moving slide to prevent the problem of over-positioning. Exemplarily, the longitudinal moving rack is fixedly arranged between the two longitudinal moving linear guides.

[0220] In a possible embodiment, the longitudinal movement drive motor is arranged on the slide 223 in the following manner: a longitudinal movement drive motor mounting component 2231 is arranged on the slide 223, such as the longitudinal movement drive motor mounting component is an annular support structure that can be sleeved on the outer side of the aforementioned longitudinal movement slide, such as the inner side of the annular support structure is provided with a guide groove that can cooperate with the aforementioned two pairs of longitudinal movement linear guide rails, and the longitudinal movement drive motor is arranged on the longitudinal movement drive motor mounting frame. For example, the annular support structure includes a vertical part and a transverse part extending outward from the bottom of the vertical part, such as the transverse part is fixed to the upper surface of the slide 223 by means of fasteners such as screws, and in order to ensure the strength of the annular support structure, a reinforcing structure such as a reinforcing plate can be added between the vertical part and the transverse part. Obviously, those skilled in the art can determine the structural form of the longitudinal movement drive motor mounting component and its assembly relationship with the slide and the longitudinal movement drive motor according to actual needs, and illustratively, the longitudinal movement drive motor mounting component can be a support frame, a U-shaped structure with one side along the circumferential direction as an open side, etc.

[0221]

Gripper assembly

[0222] In a possible implementation, the clamping jaw assembly 23 includes a fixed clamping jaw assembly 231 and an adjustable clamping jaw assembly 232 arranged along the axial direction of the silicon rod. The main functions of the clamping jaw assembly include:

[0223] 1) Silicon rods in two postures can be clamped. For example, in this example, the clamping jaw assembly can clamp the silicon rod in a V-shaped manner at 45° and in a conventional manner at 0°. For example, the silicon rod is clamped in a V-shaped manner when loading, and in a conventional vertical manner when unloading. Obviously, the clamping method can be changed according to actual needs or any of the same clamping methods can be used.

[0224] 2) The fixed jaw assembly and the adjustable jaw assembly can generate relative movement along the axial direction of the silicon rod so as to achieve reliable clamping of silicon rods of different sizes. The relative movement includes two situations:

[0225] One is that the single movement of the adjusting jaw assembly can be realized by switching the assembly (the fixed jaw assembly is in a first state, in which the fixed jaw assembly is relatively stationary and only the adjusting jaw assembly moves in a manner of approaching / moving away from the fixed jaw assembly).

[0226] The other is: the linkage between the fixed jaw assembly and the adjustable jaw assembly (the fixed jaw assembly is in the second state, in which the fixed jaw assembly and the adjustable jaw assembly are relatively still and can synchronously generate movement along the axial direction of the silicon rod).

[0227] 3) By adjusting the internal adjustment of the clamping jaw assembly, the axis of the silicon rod can be fine-tuned, so as to better meet the accurate clamping requirements of the silicon rod (rough rod) from the feeding assembly and effectively compensate for the incoming deviation of the rough rod.

[0228] 4) The center alignment of the silicon rod can be better achieved by grasping the material at a 45° angle from the loading assembly. Specifically, during the loading process, the silicon rod can be aligned with the material by grasping and clamping it at a 45° angle. In this way, there is no need to add a structure corresponding to the alignment and the alignment step is omitted. Therefore, the structure is simplified and the operation efficiency is improved while ensuring the reliability of the silicon rod posture.

[0229] In a possible implementation, the clamping jaw assembly 23 mainly includes a clamping jaw base (such as a fixed seat, etc.) 230, a fixed clamping jaw assembly 231 and an adjustable clamping jaw assembly 232 are arranged on the clamping jaw base, and the fixed clamping jaw assembly and the adjustable clamping jaw assembly can cooperate to form a clamping space for clamping a silicon rod. Among them, a clamping jaw lateral movement mechanism 233 is arranged on the clamping jaw base, and the fixed clamping jaw assembly and the adjustable clamping jaw assembly can generate relative movement towards / away from each other by means of the clamping jaw lateral movement mechanism.

[0230] In a possible embodiment, the jaw lateral movement mechanism 233 includes a jaw lateral movement drive motor 2331 and a jaw lateral movement gear chain mechanism 2332. The jaw lateral movement drive motor is connected to the gear drive of the jaw lateral movement gear chain mechanism to drive the chain meshing with the gear to move along its axial direction. The chain is provided with a first mounting position 23331 and a second mounting position 23332 along its axis. The fixed jaw assembly can be provided at the first mounting position, and the adjustable jaw assembly is fixedly provided at the second mounting position and can thus move with the movement of the chain. Exemplarily, the first / second mounting position includes a mounting seat fixed to the chain, and the mounting seats corresponding to the first / second mounting position can be the same or different. Obviously, those skilled in the art can flexibly select the specific structural form of the mounting seat and the method and position of fixing it to the chain according to actual needs.

[0231] In a possible embodiment, the jaw lateral movement mechanism is provided with a set of switching components 2334 at a position corresponding to the first installation position. When the fixed jaw assembly needs to move with the adjusting jaw assembly, the fixed jaw assembly can be switched to the first state by means of the switching component, specifically, the fixed jaw assembly is fixed to the first installation position. When the fixed jaw assembly does not need to move with the adjusting jaw assembly, the fixed jaw assembly can be switched to the second state by means of the switching component, specifically, the fixed jaw assembly is in a state where the fixed constraint relationship with the first installation position is released. In this way, the fixed jaw assembly can be switched between the first state and the second state by means of the cooperation of the switching component, the jaw lateral movement gear chain mechanism, and the mounting seat provided on the jaw lateral movement gear chain mechanism. Based on this, it is expected that the fixed jaw assembly and the adjusting jaw assembly can better meet the needs of the silicon rod in the transportation process. For example, for silicon rods of the same size, the clamping position can be flexibly adjusted according to the actual situation. For silicon rods of different sizes, a clamping position that is more suitable for them can be found.

[0232] In a possible embodiment, the switching assembly 2334 includes a switching drive component. For example, in this example, the switching drive component is a cylinder 23341, and the power output end of the cylinder is connected to a clamping block 23342. In this way, when the power output end of the cylinder is pushed downward, the clamping block can be pushed downward so that the clamping block abuts against the first mounting position or abuts against the fixed jaw assembly on the first mounting position (abuts directly or indirectly with the fixed jaw assembly), so that the fixed jaw assembly is locked with the chain. In this way, the fixed jaw assembly and the adjustment jaw assembly can move together with the movement of the chain. Accordingly, when the position of the fixed jaw assembly needs to be relatively fixed (not moving with the movement of the chain, and the adjustment jaw assembly can be close to the fixed jaw assembly with the movement of the chain), it is only necessary to retract the power output end of the cylinder upward so that the clamping block is separated from the first mounting position or the fixed jaw group arranged on the first mounting position. As in this example, the switching assembly 2334 includes a mounting frame 23343 disposed at a position corresponding to the first mounting position of the fixed jaw assembly, and the mounting seat, cylinder, clamping block and fixed jaw assembly corresponding to the first mounting position are all disposed on the mounting frame. For example, a reset structure such as a reset spring 23344 may be disposed between the mounting frame and the transfer mechanism. In this way, after the fixed jaw assembly is separated from the chain, the fixed jaw assembly and other structures disposed on the mounting frame may return to the set position of the transfer mechanism under the action of the reset spring. The reset structure may also be other structural forms such as a power cylinder, a linear module including a motor, etc. that can provide a pulling force along the set direction. Obviously, under the premise that no interference occurs, those skilled in the art may determine the specific position of the transfer mechanism corresponding to the set position returned to according to the actual situation.

[0233] It is understandable that the above structure is only one exemplary description of the switching component, and those skilled in the art can determine the structural form, the first state, the second state, and the switching method between the two of the switching component according to actual needs. For example, the constraint relationship between the clamping block and the first mounting position can be changed from abutment to other matching relationships such as plug-in, meshing, and mortise and tenon, and the switching drive component can be changed from a cylinder to other power cylinders such as a hydraulic cylinder, an electric cylinder, or a linear module with equivalent functions. In addition to the above-mentioned cylinder and clamping block assembly, any form of clutch device can also be reasonably modified to serve as the switching component of the utility model.

[0234] [Fixed jaw assembly of the jaw assembly (the first jaw assembly can achieve horizontal fine-tuning of the silicon rod axis but cannot achieve longitudinal fine-tuning)]

[0235] In a possible embodiment, the fixed jaw assembly 231 mainly includes a fixed jaw base 2311 (such as a connecting seat, etc.), a fixed jaw driving component, a fixed jaw transmission mechanism and a fixed jaw group. In this example, the fixed jaw driving component is a fixed jaw driving motor 2312, and the fixed jaw transmission mechanism is a fixed jaw lead screw nut mechanism 2313, wherein the fixed jaw group includes a first fixed jaw 23141 and a second fixed jaw 23142, such as the fixed jaw base is roughly a U-shaped connecting seat, the lead screw of the fixed jaw lead screw nut mechanism is arranged between the two vertical parts of the connecting seat, the fixed jaw driving motor is arranged on the horizontal part of the connecting seat, and the lead screw of the fixed jaw lead screw nut mechanism is provided with two sections of thread segments with opposite rotation directions, and the first fixed jaw and the second fixed jaw are respectively fixed to the two nuts of the fixed jaw lead screw nut mechanism that match the two thread segments. Based on this, the fixed jaw drive motor drives the screw in the fixed jaw screw nut mechanism to rotate, so that the (first and second) fixed jaws can move towards / away from each other at the same time, thereby completing the centering clamping function of the silicon rod. In addition, while the fixed jaw drive motor completes the feeding and clamping, the cross-sectional size of the silicon rod can also be directly calculated based on this, saving the cycle time of the feeding and transportation link.

[0236] It is understandable that the fixed jaw drive motor and the fixed jaw lead screw nut mechanism are only an exemplary description of realizing the relative movement between the first / second fixed jaws. Those skilled in the art can reasonably select the fixed jaw drive component / transmission mechanism according to actual needs. For example, if the drive transmission form remains unchanged, the fixed jaw drive motor can be changed to a rotating module that can realize movement, the fixed jaw lead screw nut mechanism can be changed to a gear rack pair, and a set of fixed jaw lead screw nut mechanisms can be configured for each of the two fixed jaws (the two fixed jaws can move relatively independently), etc. In the case of adjusting the drive transmission form, the fixed jaw drive motor can be changed to a power cylinder (such as a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc.) and other linear modules, and the fixed jaw lead screw nut mechanism can be correspondingly changed to other component forms that can realize the corresponding transmission, etc.

[0237] In a possible embodiment, the first fixed clamping jaw 23141 and the second fixed clamping jaw 23142 respectively have a first clamping position 23151 and a second clamping position 23152 on the clamping parts facing each other, so that a first clamping space can be formed between the two through a pair of first clamping positions and a second clamping space can be formed through a pair of second clamping positions, wherein the first clamping space can clamp the silicon rod with a 45° surface (first posture, V-type clamping, or inclined clamping), and the second clamping space can clamp the silicon rod with a 0° surface (second posture, vertical clamping, or 0° conventional clamping). In this way, the clamping of silicon rods in two postures can be achieved by the same set of fixed clamping jaw assemblies. In this example, the first clamping space is mainly used to clamp the silicon rod (rough rod) before grinding operation by V-type clamping, and the second clamping space is mainly used to clamp the silicon rod (finished rod) after grinding operation by vertical clamping, and the first clamping space is located below the second clamping space.

[0238] For example, when vertical clamping is required, the two fixed jaws are moved close to each other until they are in close contact with the side of the silicon rod to clamp the silicon rod. For silicon rods of the same specification (size), when V-clamping is required, the two fixed jaws are moved further close to each other so that the silicon rod can be clamped in a V-clamping manner. Compared with the vertical clamping method, the V-clamping method can achieve the coincidence of the diagonal of the silicon rod with the center of the first clamping space. Therefore, in the case of V-clamping, the centering operation of the silicon rod can be completed simultaneously during the clamping process. In addition, the cross-sectional dimensions of the silicon rod can be accurately calculated based on the opening and closing distance between the two fixed jaws.

[0239] In a possible implementation, the fixed clamping jaw assembly 231 also includes an anti-falling assembly 2316. The reason for adding the anti-falling assembly is that: when the fixed clamping jaw assembly 231 is vertically clamping the silicon rod at the 0° surface, the clamping stability of the silicon rod is mainly guaranteed by the friction between a pair of vertical clamping fitting surfaces corresponding to the second clamping space and a pair of vertical side surfaces of the silicon rod. For example, vertical clamping is used when unloading materials. Since the surface of the silicon rod after grinding is very smooth (the friction coefficient is very small), if the friction between the clamping fitting surface and the side of the silicon rod is insufficient, there may be a risk of slipping or even falling off the rod. Therefore, the cooperation between the second clamping space and the anti-falling assembly ensures the clamping reliability in the vertical clamping situation.

[0240] In a possible implementation, referring to the orientation relationship in which the first clamping space is located below the second clamping space in this example, an anti-falling assembly can be configured near the bottom of the two fixed clamping jaws. In this way, when the silicon rod is clamped in a vertical clamping manner, the anti-falling assembly can provide a certain auxiliary supporting force for the silicon rod, so that the silicon rod can be reliably clamped in the second clamping space. For example, the anti-falling assembly can be used to support the clamping reliability of the clamping jaw assembly during the period of clamping the silicon rod in a vertical clamping manner.

[0241] In a possible embodiment, the anti-falling assembly 2316 includes a pair of anti-falling hooks 23161 that are pivotally arranged corresponding to a pair of fixed jaws. When the silicon rod is clamped by a pair of fixed jaws in a vertical clamping manner, the anti-falling hook can be rotated to provide a certain auxiliary pressing force and / or supporting force. Exemplarily, the anti-falling hook includes a first hook 231611 and a second hook 231612 that are arranged at an angle, and the intersection of the first hook 231611 and the second hook 231612 is pivotally connected to the corresponding first fixed claw or the second fixed claw. In this way, when the silicon rod is clamped by a pair of fixed jaws in a vertical clamping manner, the anti-falling hook is rotated relative to the corresponding first fixed claw or the second fixed claw to such a state that the end of the first hook is abutted against the side wall of the silicon rod, and the chamfered surface between the bottom surface and the side surface of the rod (the narrow surface formed after the edge is chamfered) is abutted against the wall of the second hook. If the second hook is roughly a strip-shaped structure, the wall can be understood as a strip-shaped structure with a narrower surface (or line) in the direction of the chamfered surface between the bottom surface and the side surface facing the rod. When the wall of the second hook abuts against the chamfered surface between the bottom surface and the side surface of the rod, the pressure-bearing area is roughly a line contact or a line contact with a width (such as a narrow surface contact), so that the second hook can be used to hook the bottom of the silicon rod. Through the dual protection of increasing the clamping force on the side and increasing the supporting force on the bottom, the clamping stability of the silicon rod when it is clamped vertically can be effectively guaranteed, thereby effectively ensuring the reliability and safety of the grabbing operation performed by the second clamping position of the fixed jaw assembly.

[0242] Taking vertical clamping as an example when unloading, since the silicon rod clamped at this time is a finished rod with surface accuracy that has been ground, in order to prevent the side and chamfered surface of the finished rod from being scratched, a buffer structure such as a polyurethane layer can be provided at least at the end of the first hook and the side of the second hook.

[0243] Obviously, the structural form, number and pivot setting method of the above-mentioned anti-fall hook are only an exemplary description. Those skilled in the art can flexibly change them according to actual needs, such as: the end of the first hook has a multi-claw structure (similar to an octopus) or a deformable structure (such as silicone, etc.) to better achieve its abutment with the silicon rod; the side of the second hook is concave outward and the end has a structure similar to the first hook, so that the supporting force can be provided by double-end support; only the first hook or the second hook is included; the first hook and / or the second hook include multiple ones; the angle between the first hook and the second hook can be fixed or adjusted; the anti-fall hook can be pivotally set to the first / second fixed claw, and can also be set at any reasonable position that can achieve the rotation of the anti-fall hook without interference and does not interfere with the movement of other parts.

[0244] In a possible implementation, the anti-falling assembly 2316 also includes an anti-falling reset assembly 23162 such as a reset spring. For example, in this example, one end of the reset spring is disposed on the corresponding first fixed jaw or the second fixed jaw, and the other end is connected to a reasonable position of the anti-falling unhooking such as the outer side of the second hook. In this way, when the anti-falling assembly does not need to work, the anti-falling unhooking can be in a state such as not interfering with the clamping operation of the first clamping space under the action of the reset spring. Obviously, in addition to the reset spring, any method that can ensure the position reliability of the anti-falling unhooking in the non-working state can also be used, such as various forms of springs, structural components that can provide tension, and by extending a protrusion on the fixed jaw to achieve the position reliability of the anti-falling unhooking in the non-working state.

[0245] For example, when the silicon rod is clamped at 0°, the silicon rod is already in a horizontal position after the previous process. At this time, the first fixed jaw 23141 and the second fixed jaw 23142 first reach the expected clamping position through axial movement (synchronous movement or relative movement) according to the size of the silicon rod. After that, the pair of jaws of the first fixed jaw 23141 and the second fixed jaw 23142 approach each other to clamp the silicon rod. After the silicon rod is clamped, the anti-fall assembly is rotated at a certain angle so that the first hook and the second hook are in a working state, and the 0° conventional clamping operation can be completed. When unloading is required, the pair of jaws of the first fixed jaw 23141 and the second fixed jaw 23142 move to both sides to loosen the silicon rod, and the pair of anti-fall hooks return to the initial position of the non-interference jaw assembly under the action of the anti-fall reset assembly.

[0246] In addition, a pair of rotatable anti-falling hooks is only an exemplary description of the anti-falling component. Technical personnel in this field can choose any reasonable structural form according to actual needs to ensure the clamping stability of the second clamping space, such as providing an abutment structure that can telescopically move along the clamping direction on the two clamping surfaces of the second clamping space, and providing a tightening structure on the outside that can provide an upward supporting force for the silicon rod.

[0247] In addition, although in this example the anti-falling component plays an auxiliary role only when the second clamping space is in the working state, it is obvious that when the first clamping space is in the working state, the anti-falling component can also provide a certain auxiliary effect when necessary.

[0248] [Adjustment of the jaw assembly of the jaw assembly (the second jaw assembly can achieve horizontal fine-tuning of the silicon rod axis and also achieve longitudinal fine-tuning), and longitudinal fine-tuning of the silicon rod axis can be achieved through the first adjustment assembly]

[0249] In a possible implementation, the adjusting jaw assembly 232 mainly includes an adjusting jaw base 232 (such as a connecting seat, etc.) and an adjusting jaw group disposed on the adjusting jaw base. The adjusting jaw group includes a first adjusting jaw 23221 and a second adjusting jaw 23222. In this example, the first / second adjusting jaws are similar in structure and function to the aforementioned first / second fixed jaws, and mainly form a first clamping space and a second clamping space through the cooperation between a pair of jaws and complete V-shaped clamping and vertical clamping of the silicon rod.

[0250] Different from the aforementioned fixed jaw group, the adjusting jaw assembly further comprises a first adjusting assembly (longitudinal fine adjustment) for realizing the movement of the two adjusting jaws in the vertical direction.

[0251] In a possible implementation, the first adjustment jaw and the second adjustment jaw are equipped with a set of first adjustment components, and the first adjustment components can realize the movement of the first / second adjustment jaw along the longitudinal direction (vertical direction) thereof.

[0252] In a possible embodiment, the first adjustment assembly includes a second adjustment drive motor 23231 (first adjustment drive component), a first adjustment cam 23232 (first adjustment transmission mechanism) and a first adjustment guide structure 23233, a reserved space is provided on the connection bracket of the adjustment jaw base, the power output shaft of the first adjustment drive motor is connected to the first adjustment cam and the cam is freely accommodated in the reserved space and abuts against the connection bracket (such as line contact or narrow surface contact), and the first adjustment guide structure is arranged on the bracket body of the adjustment jaw base and only allows the first / second adjustment jaw to move in the vertical direction. As in this example, the reserved space is a circular hole, and the first adjustment cam abuts against the connection bracket corresponding to the position of the circular hole near the top. If the first adjustment guide structure is a first adjustment linear slide rail, a groove structure matching the first adjustment linear slide rail is correspondingly provided on the connection bracket of the adjustment jaw base. For example, the reserved space can also be other structural forms such as a square hole or a groove with an open bottom side, and the first adjustment guide structure can also be other structures such as an optical axis. In this way, under the driving action of the first adjustment drive motor, the first adjustment cam abuts against the position near the top of the reserved space, thereby driving the connecting bracket of the adjustment jaw base to move in the vertical direction and thereby driving the first / second adjustment jaw to move (the first / second adjustment jaw is connected to the first adjustment linear guide rail of the connecting bracket arranged on the aforementioned adjustment jaw base). At the same time, due to the constraint of the first adjustment guide structure, the first / second adjustment jaw can achieve fine-tuning of its position along the longitudinal direction.

[0253] In this way, when the axis of the silicon rod in the clamped state is slightly offset from the horizontal direction (an angle is formed between the axis of the silicon rod and the horizontal plane), the two adjustment claws of the adjustment jaw assembly can be driven by the second adjustment assembly to move synchronously in the longitudinal direction, thereby causing a certain height difference between the clamping position of the silicon rod in the fixed clamping jaw assembly and the clamping position corresponding to the adjustment clamping jaw assembly. Such a height difference can effectively suppress the offset of the corresponding center axis relative to the horizontal plane.

[0254] It is understandable that the structural form of the aforementioned first adjustment component is only an exemplary description, and those skilled in the art can flexibly change it according to actual needs, such as changing the cam to an eccentric shaft or other eccentric structures. In addition, a first adjustment component can be configured for each of the first / second adjustment clamps, or a part of the first adjustment components of the two can be shared. And, under the premise of being able to achieve lifting in the height direction, other drive transmission forms can also be adopted to achieve it, such as changing the drive motor to a power cylinder, a linear module, a rotating module, etc., such as changing the cam to a screw nut mechanism, a worm gear pair, a gear rack mechanism, a sprocket chain mechanism, etc. Exemplarily, the power cylinder pushes a pair of connecting blocks with inclined surfaces to move, and the inclined surfaces of the pair of connecting blocks are respectively provided with lifting wheels that can roll along them, and the wheel axles of the lifting wheels are arranged on the connecting bracket of the adjustment clamp base.

[0255] In a possible implementation, based on the aforementioned fixed jaw assembly and adjustable jaw assembly, the jaw assembly 23 further includes a second adjustment assembly, wherein the fixed jaw assembly and the adjustable jaw assembly share a set of second adjustment assemblies, and the function of the second adjustment assembly is: when the axis of the silicon rod is offset left and right in the horizontal plane, the axis of the silicon rod is made to coincide with the ideal position by rotating the silicon rod as a whole and the fixed jaw assembly and the adjustable jaw assembly and other related structures that clamp the silicon rod. Therefore, the second adjustment assembly mainly ensures the clamping accuracy of the axis of the silicon rod in the horizontal plane by performing a whole lateral micro-rotation of the fixed jaw assembly and the adjustable jaw assembly.

[0256] In a possible embodiment, the second adjustment component includes a second adjustment drive component and a second adjustment transmission mechanism. For example, in this example, the second adjustment drive component is a second adjustment drive motor 23241, and the second adjustment transmission mechanism includes a second adjustment cam 23242. The bottom of the longitudinal moving slide 2221 of the longitudinal moving component 222 is pivotally connected to the clamping base 230 of the clamping assembly 23. In this way, the position of the axis of the silicon rod clamped between the fixed clamping assembly and the adjusting clamping assembly in the horizontal plane can be fine-tuned by rotating the clamping base 230 and the fixed / adjusting clamping assembly thereon slightly relative to the longitudinal moving slide 2221.

[0257] In a possible embodiment, the longitudinal movable slide 2221 is pivotally connected to the clamping jaw base 230 through a second adjustment rotation center assembly. For example, in this example, the second adjustment rotation center assembly includes a cross roller bearing 23243. A second adjustment connection component 22211 is provided at the bottom of the longitudinal movable slide 2221. For example, the second adjustment connection component is generally a connecting plate. The cross roller bearing 23243 is provided between the connecting plate and the clamping jaw base. The second adjustment drive motor 23241 is fixed to the side of the clamping jaw base 230 corresponding to the adjustment clamping jaw assembly 232. A second adjustment hole 222111 capable of cooperating with the second adjustment cam is provided on the connecting plate. The outer edge of the second adjustment cam can abut against the hole wall of the second adjustment hole. In this way, when the axis of the silicon rod has a certain deviation in the horizontal plane, the second adjustment drive motor 23241 drives the second adjustment cam to rotate in the second adjustment hole. Since the longitudinal movable slide 2221 cannot rotate under the restriction of the slide, the clamping jaw base 230 can be slightly rotated relative to the longitudinal movable slide 2221. Based on this micro-rotation, the position of the axis of the silicon rod in the horizontal plane can be slightly adjusted. On this basis, it is expected to achieve the clamping accuracy of the axis of the silicon rod in the horizontal plane.

[0258] It can be understood that the structural form of the aforementioned second adjustment component is only an exemplary description, and technical personnel in this field can flexibly change it according to actual needs. For example, the second adjustment transmission mechanism can be any other form of eccentric structure, and it can also be a screw nut mechanism, a worm gear mechanism, a gear rack mechanism, a sprocket chain mechanism, etc. The second adjustment drive component can be any form of rotating module, power cylinder (such as a cylinder, a hydraulic cylinder, an electric cylinder, etc.) and any form of linear module, etc. The second adjustment rotating center component can be any structure that can achieve pivotal connection, such as a rotating shaft and a turntable.

[0259] In addition, although in this example, the second adjustment drive motor and the second adjustment cam are arranged on a side close to the adjustment jaw assembly, it is obvious that they can also be arranged on a side close to the fixed jaw assembly or the second adjustment drive / transmission structure can be arranged on both sides. Of course, in the case where pivoting is achievable, the second adjustment drive / transmission structure can also be directly arranged at a position close to the second adjustment rotation center assembly, such as by using the second adjustment drive / transmission structure as a rotation structure / module, and the second adjustment rotation structure / module directly drives the second adjustment rotation center assembly to rotate.

[0260] It can be seen that in a preferred embodiment of the utility model, the longitudinal fine-tuning of the axis of the silicon rod in the vertical direction can be achieved through the setting of the aforementioned first adjustment component. Through the setting of the second adjustment component, the overall micro-rotation of the clamping jaw base and the fixed / adjusting clamping jaw assembly arranged on the clamping jaw base can achieve fine-tuning of the axis position of the silicon rod in the horizontal plane. Specifically, if the central axis of the silicon rod is offset in the vertical direction when the silicon rod is clamped, the first adjustment component can be used to drive the first adjustment cam to rotate the silicon rod relative to the slide. If the central axis of the silicon rod is offset in the horizontal plane when the silicon rod is clamped, the second adjustment component can be used to drive the second adjustment cam to rotate the silicon rod relative to the slide. The movement is performed synchronously in the direction that can suppress the offset, so that the horizontal position accuracy of the silicon rod can be guaranteed.

[0261] It should be noted that in the description of this embodiment, the adjusting jaw assembly is configured with a first adjusting assembly alone, and the fixed jaw assembly and the adjusting jaw assembly share a second adjusting assembly. Since the second adjusting drive component / transmission mechanism of the second adjusting assembly is configured on a side close to the adjusting jaw, for the convenience of description, the jaw assembly for clamping the silicon rod is described after being divided into a fixed jaw assembly and an adjusting jaw assembly. However, in fact, the fixed jaw assembly also participates in the fine-tuning of the axis of the silicon rod in the horizontal plane. That is, the adjustment object of the first adjustment assembly is the adjusting jaw assembly, and the adjustment object of the second adjustment assembly is the structure including the fixed jaw assembly, the adjusting jaw assembly and the jaw base.

[0262] In a possible implementation, a first adjustment jaw and a second adjustment jaw are each equipped with a pair of photoelectric switches on both sides along the axial direction of the silicon rod, and the two pairs of photoelectric switches are mainly used to measure the length of the silicon rod before loading. The following describes the determination of the length of the silicon rod using a pair of photoelectric switches (respectively referred to as the first photoelectric switch and the second photoelectric switch) configured on the first adjustment jaw.

[0263] For example, the process of clamping a silicon rod by a fixed jaw assembly and an adjustable jaw assembly is usually as follows: first, the fixed jaw assembly clamps one side of the silicon rod, and then the adjustable jaw assembly starts from the initial clamping position of the silicon rod and moves along the length direction of the silicon rod. It is known that the distance between the initial clamping position of the adjustable jaw assembly and the front end (left side) of the silicon rod is a, the distance between the first opposite-shooting photoelectric switch on the left and the center of the first adjusting jaw is n, and the distance between the second opposite-shooting photoelectric switch on the right and the center of the first adjusting jaw is m.

[0264] Based on this, for a silicon rod with a longer length, the first / second paired photoelectric switch can both receive signals, and the first / second adjustment jaw can be moved along the axis direction of the silicon rod until the second paired photoelectric switch on the right side receives no signal. At this time, according to the detected distance x of the first / second adjustment jaw moving to the right, the length L=a+m+x of the silicon rod can be determined. For a silicon rod with a shorter length, the first paired photoelectric switch on the left side can receive signals while the second paired photoelectric switch on the right side cannot receive signals, and the first / second adjustment jaw can be moved along the axis direction of the silicon rod until the first paired photoelectric switch on the left side receives no signal. At this time, according to the detected distance x of the first / second adjustment jaw moving to the right, the length L=a+xn of the silicon rod can be determined.

[0265] Based on the above structure, in a possible implementation mode, for any grinding unit in the grinding machine production line of the utility model, the main operations of the transfer mechanism 2 include four steps: V-shaped grabbing of rough rods, V-shaped loading, 0° grabbing of finished rods, and 0° placement of finished rods (unloading).

[0266] 1. V-shaped grabbing stick:

[0267] In a possible embodiment, when the transfer mechanism is ready to load and clamp the rough rod to be ground, the slide moves horizontally along the gantry with the help of the lateral moving assembly, thereby driving the clamping assembly arranged on the slide to move to the top of the loading assembly, and the clamping assembly moves downward with the help of the longitudinal moving assembly to a loading clamping position capable of grabbing the V-shaped rough rod placed on the loading assembly, and the clamping assembly is fixed / adjusted to release the first clamping space so as to smoothly clamp the silicon rod on this basis.

[0268] For example, the usual clamping process is: first, the two fixed jaws of the fixed jaw assembly use the first clamping space corresponding to the V-shaped clamping to clamp the silicon rod, and because the first clamping space and the silicon rod at this time have a matching V-shaped posture, the centering operation of the silicon rod can be completed while the silicon rod is clamped. When the clamping operation of the fixed jaw assembly has been completed, the adjustment jaw assembly is moved along the length direction of the silicon rod (with the help of the switching assembly to put the fixed jaw assembly in the second state) to the set position and the two adjustment jaws are brought close to each other to clamp the rod. In this process, the length of the silicon rod can be measured by two pairs of opposing photoelectric switches configured on the adjustment jaw assembly.

[0269] In the case where the posture of the silicon rod in the clamped state is slightly offset, the position of the silicon rod can be adjusted by adjusting the clamping jaw assembly. Specifically, if there is a certain displacement (lateral deviation) between the central axis of the silicon rod and the ideal position (vertical plane) when the silicon rod is clamped, the deviation can be suppressed / eliminated by the first adjustment assembly. And if there is a certain angle (longitudinal deviation) between the central axis of the silicon rod and the horizontal plane when the silicon rod is clamped, the deviation can be suppressed / eliminated by the second adjustment assembly.

[0270] 2. V-type feeding:

[0271] After the clamping of the silicon rod is completed, the longitudinal moving assembly drives the jaw assembly holding the silicon rod to move vertically upward, and the slide including the longitudinal moving assembly and the jaw assembly moves along the gantry through the transverse moving assembly to reach the top of the clamping position corresponding to the grinding assembly. On this basis, the jaw assembly holding the silicon rod moves vertically downward through the longitudinal moving assembly to reach the clamping position of the grinding assembly. When the clamping assembly of the grinding assembly begins to clamp the silicon rod, the potential energy of the jaw assembly is removed so that the jaw assembly can move with the movement of the silicon rod. After the clamping assembly of the grinding assembly clamps the silicon rod firmly, the fixed jaw assembly and the adjustment jaw assembly of the jaw assembly release each other, thereby releasing the first clamping space (the jaw assembly releases the silicon rod).

[0272] After the clamping jaw assembly releases the constraint on the silicon rod, similar to the aforementioned approach principle, the clamping jaw assembly can be driven to a position that does not interfere with grinding through the aforementioned lateral moving assembly and longitudinal moving assembly, such as a position corresponding to other grinding stations on the grinding machine production line or a specified position (such as a position close to the end of the gantry, or still located at the current grinding station but in a position that does not interfere with the grinding operation (such as a waiting grinding position), and then the grinding assembly can be used to grind the sides and edges of the silicon rod.

[0273] 3. Grab the finished rod at 0°:

[0274] After the grinding operation of the silicon rod is completed, a finished rod with surface accuracy that meets the standard can be obtained. At this time, the jaw assembly (the second clamping space) moves to the post-grinding clamping position of the silicon rod through the lateral moving assembly and the longitudinal moving assembly. On this basis, the fixed jaw assembly and the adjustable jaw assembly of the jaw assembly are brought close to each other and the finished rod is grasped in a conventional 0° clamping manner. At this time, the two pairs of anti-falling hooks of the anti-falling assembly are pivoted to a position that can provide auxiliary pressing force / supporting force to the finished rod to prevent the silicon rod with surface accuracy that meets the standard from slipping or even falling off.

[0275] After the silicon rod is grasped, the clamping jaw assembly moves vertically upward through the longitudinal moving assembly, and the clamping jaw assembly including the longitudinal moving assembly and the slide moves to a material unloading position corresponding to the material unloading assembly through the transverse moving assembly.

[0276] 4. 0° blanking:

[0277] After the jaw assembly moves vertically downward to the unloading position corresponding to the unloading assembly through the longitudinal moving assembly, the fixed jaw assembly and the adjusting jaw assembly of the jaw assembly are released from each other, and the two pairs of anti-falling hooks on the adjusting jaw assembly are pivoted and released, thereby releasing the second clamping space. At this time, the silicon rod can fall onto the unloading table of the unloading assembly, and a complete operation is completed. For example, the finished rod can be connected with the unloading assembly through AGV, etc., so as to be transported to a position such as a workstation of a slicer corresponding to the downstream process.

[0278] Afterwards, the gripper assembly including the slide and the longitudinal movement assembly can be moved back to the loading position of the grinding production line to prepare for the second loading and grabbing.

[0279] In a specific embodiment, in the grinding machine production line of the utility model, the operation process for any grinding operation generally includes the following steps:

[0280] S1. Place the silicon rod (rough rod to be processed) on the loading assembly.

[0281] S2. The lateral moving assembly is started, and the clamping jaw assembly is thus transferred laterally to a loading position corresponding to the loading assembly.

[0282] S3. The fixed jaw assembly and the adjusting jaw assembly of the jaw assembly are opened to a position where the silicon rod can be freely accommodated, such as a pair of jaws of the fixed jaw assembly and the adjusting jaw assembly are opened to the maximum position.

[0283] S4, the clamping jaw assembly clamps the silicon rod. During this process, in order to ensure the clamping accuracy, the posture of the silicon rod may need to be fine-tuned by the first / second adjustment assembly.

[0284] S5. The longitudinal moving assembly starts, and the gripper assembly grabs the silicon rod upward.

[0285] S6. The lateral moving assembly is started, and the clamping jaw assembly moves laterally to the grinding station corresponding to the grinding assembly (located above the grinding processing area).

[0286] S7, the longitudinal moving assembly is started, the clamping assembly moves downward to the position corresponding to the clamping assembly, and then moves upward to the waiting state. At this time, the silicon rod can be ground at the current grinding station.

[0287] S8. After the grinding operation is completed, the longitudinal moving assembly is started, and the clamping jaw assembly moves downward to the position of the grinding assembly and clamps the silicon rod. After that, the clamping jaw assembly moves upward to a state where the material can be unloaded without interfering with the grinding assembly.

[0288] S9, the lateral moving assembly is started, and the clamping jaw assembly moves laterally to the unloading position corresponding to the unloading assembly.

[0289] S10, the fixed jaw assembly and the adjusting jaw assembly of the jaw assembly loosen the silicon rod, thereby transferring the silicon rod to the unloading station of the unloading assembly.

[0290] In a possible implementation, in the grinding machine production line of the present invention, the loading assembly and the unloading assembly are located on the same side of the gantry assembly (the left side in the figure). In this way, the integration of the grinding machine production line is improved. In addition, when the grinding machine production line is equipped with a cantilever hanging assembly, only one set of cantilever hanging assembly is needed to realize the auxiliary operations for the loading and unloading links, which saves costs and reduces the corresponding space occupied while ensuring full functions.

[0291] At this point, the single grinding operation of a single silicon rod in the grinding machine production line, including transfer, is completed.

[0292] Based on similar logic, multiple grinding stations of the grinding machine production line can be put into working state. For example, after the transfer mechanism completes the loading operation of grinding station one, it can then complete the unloading operation of grinding station two, the loading operation of grinding station three, and the waiting state.

[0293] [Grinding operation method in which the clamping assembly and the silicon rod it holds are stationary and the grinding assembly reciprocates]

[0294] The current grinders mainly include two types: horizontal grinders and vertical grinders. The horizontal grinders generally include a movable slide that can move along the length direction of the silicon rod, a clamping assembly that can clamp the silicon rod and a grinding assembly that can grind the silicon rod. Based on such a structure, the workflow of the existing grinders for grinding silicon rods is as follows: the clamping assembly clamps the silicon rod (the clamping assembly generally includes a movable chuck and a fixed chuck, and the movable chuck moves relative to the fixed chuck to clamp the silicon rod), and the clamping assembly that clamps the silicon rod is driven to slide on the movable slide, so that the grinding assembly that is relatively fixed in position along the length direction of the silicon rod can grind the side and chamfer of the entire length range of the silicon rod along with the sliding of the clamping assembly, thereby completing the grinding operation of the silicon rod. Taking the workpiece to be processed as a silicon rod as an example, the process of grinding the silicon rod is usually as follows: first, the squared silicon rod (the aforementioned rough rod) is fixed to the loading device, and after the initial adjustment of the posture of the silicon rod, the silicon rod is delivered between the two chucks of the feed slide device, and the silicon rod is delivered to the position corresponding to the grinding assembly by the movement of the feed slide device along the axial direction (feed direction) of the silicon rod. Based on this, by bringing the grinding assembly close to the silicon rod and reciprocating the silicon rod along the feed direction, one group of surfaces to be ground or a pair of edges of the silicon rod can be subjected to corresponding grinding operations. Afterwards, by rotating the silicon rod, it is rotated to the second group of surfaces to be ground or another pair of edges, and so on, the rough rod can be processed into a finished rod by a grinder as described above.

[0295] It can be seen that the current horizontal grinder mainly relies on the reciprocating motion of the silicon rod along the feed direction to complete its grinding operation. Since the reciprocating motion of the silicon rod requires a large moving stroke, the linear operation corresponding to the large moving stroke will have a certain impact on the accuracy of the silicon rod after grinding (such as the straightness of the linear guide matching the linear motion has a greater impact on the accuracy of the silicon rod). Such an impact will bring a large grinding allowance, and the grinding accuracy of the silicon rod will not meet the standard. Therefore, after careful analysis and research, the inventor proposed a grinder as a single grinder of a grinding machine production line. During the grinding of the silicon rod by the single grinder, the processing method of the grinder is that the silicon rod does not move, and the grinding component that performs the grinding operation on the silicon rod reciprocates along the axial direction of the silicon rod.

[0296] Different from the existing grinding machines, the grinding machine of the utility model adopts an operation mode in which the grinding assembly 1 moves along the length direction of the silicon rod 8, and the clamping assembly 18 (usually including a fixed chuck and a movable chuck, or both movable chucks) is relatively fixed in position after the silicon rod is clamped. Specifically, the movement of the grinding assembly during the grinding operation of the silicon rod includes rotational movement and linear movement along the length direction of the silicon rod. Among them, the grinding assembly usually includes a rough grinding wheel and a fine grinding wheel, and the rotational movement is mainly to grind the surface of the silicon rod by rotating the rough grinding wheel and the fine grinding wheel while ensuring a certain cutting depth and cutting force along the radial direction of the silicon rod. Along with the linear movement of the grinding assembly along the length direction of the silicon rod, the chamfer between the side of the silicon rod and the adjacent side can be ground. Exemplarily, the linear motion of the grinding assembly along the length direction of the silicon rod is achieved as follows: the grinding machine includes a slide mechanism, and the grinding assemblies arranged in pairs are slidably arranged on the slide mechanism, so that under the action of corresponding driving transmission components, the grinding assemblies can move along the length direction of the silicon rod.

[0297] In a possible implementation, the grinding assembly 1 mainly includes a fine grinding wheel 11 for fine grinding of silicon rods, and a rough grinding wheel 12 for rough grinding of silicon rods. In the present invention, the rough grinding wheel and the fine grinding wheel are concentrically arranged at the same station, and the rough grinding wheel is freely accommodated in the reserved space formed inside the fine grinding wheel. In this way, the grinding assembly can realize rough grinding and fine grinding of silicon rods at the same station.

[0298] In a possible embodiment, the grinding assembly also includes a composite shaft, the composite shaft includes a bearing box 13, the bearing box includes a first transmission shaft (bushing) 14 of a cylindrical structure and a second transmission shaft 15 (inner shaft) accommodated in the cylindrical structure, wherein the bushing is connected to the fine grinding wheel so as to drive the fine grinding wheel to be connected when the bushing rotates, and the second transmission shaft is connected to the rough grinding wheel so as to drive the rough grinding wheel to be connected when the second transmission shaft rotates. The first transmission shaft and the second transmission shaft are connected by a guide flat key, so that the first transmission shaft and the second transmission shaft can be driven to rotate synchronously by a driving component such as a motor. Exemplarily, the motor 16 is connected to the rear end of the composite shaft through a pulley mechanism 17 and thus drives the first transmission shaft and the second transmission shaft to rotate synchronously.

[0299] In a possible embodiment, the grinding assembly 1 also includes a clamping assembly 18 located at the grinding station, and the movable chuck of the clamping assembly can move relative to the fixed chuck, so that after the silicon rod to be ground is clamped by the clamping assembly, the silicon rod is ground by the cooperation of the rough grinding wheel and the fine grinding wheel.

[0300] Based on this, a mechanism is mainly configured for the second transmission shaft corresponding to the rough grinding wheel to realize its extension and retraction, so as to realize the switching of the rough grinding operation and the fine grinding operation. Specifically, when the silicon rod needs to be rough ground, it is extended relative to the fine grinding wheel, and when the silicon rod needs to be fine ground, it is retracted relative to the fine grinding wheel (reserved space). Exemplarily, one way to realize the switching of the rough grinding operation and the fine grinding operation of the rough grinding wheel is that the telescopic mechanism includes a spring, and the second transmission shaft is in a state of retraction relative to the fine grinding wheel under the action of the preload force of the spring. In this way, when the silicon rod needs to be fine ground, it is sufficient to maintain a state without external force. And when the silicon rod needs to be rough ground, the rough grinding wheel associated with it is extended out of the fine grinding wheel by applying external force to the spring. For example, an external force mechanism such as a power cylinder, a linear module, or a drive transmission mechanism capable of realizing telescopic movement can be used to apply an external force to the pressure cover supporting the rear end of the bearing box, so that the spring is deformed under the action of the external force and the rough grinding wheel is extended.

[0301] Compared with the method of separately setting the stations for the rough grinding wheel and the fine grinding wheel, the grinding assembly of the utility model integrates the rough grinding wheel and the fine grinding wheel with the help of the bearing box and sets them in the same station, that is, each grinding station of the grinding machine production line only needs to reserve the same station area to realize the rough grinding and fine grinding operations of the silicon rod at the same time, and the structure is more compact, which greatly reduces the installation space of the grinding assembly. Corresponding to the centralized setting of the rough grinding wheel and the fine grinding wheel in the same station area, each grinding station will reduce a set of supporting mechanisms of the grinding assembly, thereby saving the number of components and reducing the equipment cost of the grinding machine production line. In addition, since the grinding assembly of the utility model needs to reciprocate along the length direction of the silicon rod, the integrated setting can also effectively avoid problems such as the impact on grinding accuracy caused by the movement of multiple components, and is therefore more suitable for the grinding operation method in the grinding machine production line of the utility model.

[0302] In a possible embodiment, the structures of the loading assembly and the unloading assembly are roughly the same, that is, the grinding machine production line adopts the same structure that can be used as the loading assembly and the unloading assembly (such as being called the loading and unloading assembly). In a possible embodiment, the loading and unloading assembly mainly includes a storage table assembly, a table assembly and a table flip assembly, wherein the table assembly can transfer the silicon rods (rough rods) to be processed to a designated position to wait for loading, or receive processed silicon rods (finished rods) for unloading. The storage table assembly can be placed on the square rods waiting for loading / unloading, and the square rods can be transferred along their length direction. The table flip assembly is configured on the table assembly, and the table flip assembly can flip the square rods placed therein along the axis of the square rods at a certain angle according to the requirements of loading / unloading, such as corresponding to the aforementioned loading requirements (first clamping space) to the state where the angle between the side and the horizontal plane is 45° or corresponding to the aforementioned unloading requirements (second clamping space) to the state where the angle between the side and the horizontal plane is 0°.

[0303] In a possible implementation, a connection component is provided between the material storage platform component and the material platform component, so that the square rods can be smoothly transferred between the material storage platform component and the material platform component, and through such connection, the upper and lower material components can better adapt to the transportation requirements of square rods of different lengths. For example, detection components such as photoelectric switches are configured on the material storage platform component and the material platform component to detect the presence or absence of silicon rods, the length of the rods, etc. For example, photoelectric switches are provided at the front end of the material platform component and the front, middle, and rear ends of the material storage platform component.

[0304] In a possible implementation, the material platform flip assembly mainly includes a material platform flip driving component and a material platform flip bracket, wherein the material platform flip bracket is pivotally arranged on the aforementioned material platform frame and forms a bearing space capable of bearing silicon rods, and the material platform flip driving component is used to drive the material platform flip bracket to flip relative to the material platform frame and thus change the posture of the silicon rods carried thereon. In this example, the material platform flip bracket includes a bottom wall portion and a side wall portion.

[0305] In a possible embodiment, the material table flip bracket is pivotally arranged on the aforementioned material table frame in the following manner: two flip shaft support seats equipped with bearings are arranged at the bottom of the material table flip bracket, and the flip shaft support seats are fixedly arranged on the material table frame, such as a flip shaft guide seat can be arranged between the two flip shaft support seats, and the flip shaft is pivotally arranged on the flip shaft support seat and the flip shaft guide seat. The material table flip driving component drives the material table flip bracket to flip by driving the flip shaft to rotate. Since the material table flip bracket needs to be in direct contact with the silicon rod, a material or structure with a buffering function can be arranged on the material table flip bracket, such as adding a non-metallic protective plate inside the material table flip bracket.

[0306] In a possible embodiment, a material platform flipping clamping assembly is provided at a position near the end of the material platform flipping bracket in the length direction and opposite to the side wall portion of the flipping bracket, so as to clamp the silicon rods when they rotate to ensure the reliability of the flipping operation.

[0307] In a possible implementation, the material table flipping bracket is provided with a material table flipping guide wheel near the end in the length direction thereof, and a first material table flipping detection switch is provided near the material table guide wheel to detect whether the silicon rods are delivered to the right position.

[0308] In a possible embodiment, the material table flipping driving component is a power cylinder (such as a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc., and obviously it can also be a mechanism or a motor that can provide linear drive composed of a linear module, a driving component and a transmission component. For example, in the case where the material table flipping driving component is a motor, the power output shaft of the motor should be connected to the flipping axis), the power cylinder is fixed to the aforementioned material table support seat, and the power output end of the power cylinder is fixed to the material table flipping bracket. In this way, by extending or retracting the power output end of the power cylinder, the material table flipping bracket can be rotated around the flipping axis, thereby changing the posture of the silicon rods carried thereon.

[0309] In a possible embodiment, the material platform flipping assembly is also provided with a material platform flipping limit assembly to determine the flipping range of the discharging platform flipping assembly. Exemplarily, the material platform flipping limit assembly includes a material platform flipping limit base, a material platform flipping limit screw and a material platform flipping buffer arranged thereon. The flipping angle of the flipping assembly can be adjusted by adjusting the material platform flipping limit screw, and the material platform flipping buffer is used to buffer the flipping motion with the help of the buffer when the flipping is in place, thereby protecting the silicon rods. In addition, a material platform flipping detection switch can be respectively provided at the initial position and the flipping position of the material platform flipping assembly to detect whether the material platform flipping assembly has returned to the initial position and whether it has flipped in place.

[0310] In a possible embodiment, the material storage platform assembly mainly includes a material storage platform frame and a material storage platform transmission mechanism arranged on the material storage platform frame, wherein the material storage platform transmission mechanism is similar to the aforementioned material storage platform assembly, and the silicon rod is also realized by belt transmission, which will not be repeated here. Exemplarily, since the material storage platform assembly needs to be connected with the external environment, a plurality of casters and foot cups can be provided at the bottom of the material storage platform frame, and when the material storage platform assembly needs to be moved, the foot cup is lifted (the caster is in contact with the ground at this time). When the material storage platform assembly needs to be fixed, the foot cup is put down (the foot cup is in contact with the ground at this time). For example, the combination of the foot cup and the caster can also be replaced by a forma wheel, etc.

[0311] It can be understood that the belt drive and its specific form are only an exemplary description of the material table / storage table transmission mechanism. Technical personnel in this field can adopt other structural forms of belt drives or other transmission methods besides belt drives to realize the transportation of silicon rods according to actual needs. For example, in addition to belt drives, the transportation of silicon rods can also be realized through the cooperation of sprockets and chains, belts and pulleys, guide rails and screw nut mechanisms, guide rails and gear rack pairs, power cylinders and guide rails, etc.

[0312] In a possible embodiment, the connection assembly includes a connection bracket and a transition wheel assembly disposed on the connection bracket, and the transition wheel assembly includes a pair of first transition wheels (such as radially larger rollers, hereinafter referred to as large rollers) pivotally disposed on the connection bracket. Exemplarily, the large roller is pivotally disposed on the connection bracket in the following manner: the large roller is disposed on the transition wheel shaft, and the transition wheel shaft is disposed between a pair of transition wheel support seats fixedly disposed on the connection bracket. For example, in this example, the connection bracket is a bracket of a roughly L-shaped structure, the transition wheel shaft support seat is disposed on the lateral portion of the connection bracket, and the vertical portion of the connection bracket is mounted to the front end position of the storage platform frame of the aforementioned storage platform assembly.

[0313] In a possible embodiment, a driven sprocket is provided on the transition wheel shaft, a driving sprocket is provided on the driven shaft of the storage platform assembly, and the driving sprocket and the driven sprocket are connected by a chain. A plurality of pairs of second transition wheels (such as radially smaller rollers, hereinafter referred to as small rollers) are also pivotally provided on the connection bracket. For example, in this example, a pair of small rollers are respectively arranged on both sides of a pair of large rollers along the conveying direction. For example, the surface of the large / small rollers should be a structure or material (such as a non-metallic material) that will not cause damage to the surface of the silicon rod. Through such an arrangement, it can be ensured that the silicon rod is better connected between the material platform assembly and the storage platform assembly, and can adapt to the transmission of square rods of various lengths.

[0314] It can be understood that the transmission of silicon rods on the transition wheel assembly through the cooperation of sprockets and chains is only one of the implementation forms. Technical personnel in this field can flexibly change it according to actual needs. For example, the driving sprocket can be set on the driving shaft of the material table assembly, and the cooperation of the sprocket and the chain can be changed to other methods such as the cooperation of gear pairs, synchronous belts and synchronous pulleys, belts and pulleys, guide rails and screw nut mechanisms, guide rails and gear rack pairs, cylinders and guide rails.

[0315] Based on the above structure, when the loading and unloading assembly is used as the loading assembly of the grinder, its working process generally includes: the silicon rods (rough rods) to be loaded can be placed in the carrying space of the storage table assembly by manual, robot, truss manipulator, KBK, AGV, conveyor line, etc., and the length of the silicon rods can be determined by the detection assembly. The storage table drive motor is started to smoothly convey the silicon rods to the material table assembly through the connection assembly by belt transmission. The material table assembly drive motor is started to convey the silicon rods into place by belt transmission (first material table detection switch). The material table flipping and clamping assembly presses the silicon against the side wall of the flip bracket. Under the action of the flipping drive component, the silicon rod flips 45° according to the demand to meet the loading demand compatible with the first clamping space mentioned above. The material table detection switch can detect whether the silicon rod is flipped into place. After flipping into place, the material table flipping and clamping assembly can release the silicon rod for the next step of grabbing.

[0316] When the loading and unloading assembly is used as the unloading assembly of the grinder, its working process generally includes: according to the unloading demand, the material table flip assembly flips to the 0° regular position to receive the silicon rods (finished rods) unloaded vertically, and the material table flip pressing assembly presses the finished silicon rods against the inner side of the side wall of the material table flip bracket. Under the action of the flip driving component, the material table flip assembly drives the rods back to the 0° position. When the second flip detection switch detects whether the silicon rods return to the 0° position, the material table flip pressing assembly releases the rods to facilitate the next step of unloading and transportation. If the unloading demand does not require the rods to flip, the flip-related actions can be omitted. The material table drive motor starts, and the silicon rods are output outward by belt transmission. In order to ensure the effectiveness of the connection assembly, the storage table drive component must also be started when the silicon rods have not reached the storage table assembly. If necessary, the silicon rods can be transported to any position of the storage table assembly to meet the smooth connection with unloading methods such as manual, robot, truss manipulator, KBK, AGV, and conveyor line.

[0317] In one possible embodiment, a storage table flip assembly is provided at the end of the storage table assembly away from the storage table assembly along the length direction of the silicon rods, so that when the storage table assembly is flipped open to the spliced ​​state, it can meet the storage needs of silicon rods with longer lengths, and when the storage table assembly is flipped and folded, it can meet the storage needs of silicon rods with shorter lengths.

[0318] In a possible embodiment, the material storage table flip assembly mainly includes a material storage table flip plate. Similar to the aforementioned material storage table flip plate, a non-metallic protective block is installed on the inner side (bottom wall and side wall) of the material storage table flip plate. A pair of mounting plates are extended downward from the material storage table flip plate. An elongated hole extending in the vertical direction is provided on the mounting plate, and an arc-shaped slot hole is provided at the bottom end of the elongated hole. A non-metallic protective block is installed on the material storage table flip plate. A pair of mounting blocks corresponding to the pair of mounting plates are provided on the material storage table flip plate. A blocking screw, a first rotating shaft adapted to the elongated hole, and a second rotating shaft adapted to the slot hole are provided on the mounting blocks. In this way, the state switching of the material storage table flip plate can be realized through two sets of cooperation.

[0319] When the length of the storage platform assembly is insufficient and the storage platform flip assembly needs to be used, the storage platform flip plate is dropped so that the two rotating shafts on the mounting block are respectively at the top of the two long holes of the storage platform flip bracket. The storage platform flip plate can be placed in a horizontal position by blocking the screws, which can lengthen and extend the storage platform assembly to accommodate the placement of rectangular bars. When the length of the storage platform assembly is sufficient, the storage platform flip plate is lifted so that the two rotating shafts on the mounting block are respectively at the bottom of the two long holes of the storage platform flip bracket. The storage platform flip plate is rotated so that the storage platform flip plate rotates around the upper rotating shaft, so that the storage platform flip plate can be placed in a vertical position, saving space. That is, when the length of the silicon rod is long and the length of the storage platform assembly is insufficient, the storage platform flip plate is unfolded, so that the storage platform assembly can be lengthened and extended, so that it can better accommodate the placement of long bars. When the silicon rod is short and the storage table assembly is long enough, the storage table flip plate is folded, thereby effectively saving the space occupied by the storage table assembly along the length of the silicon rod without interfering with the function of the storage table assembly.

[0320] In a possible implementation, the loading and unloading assembly further includes a protection assembly, which is mainly used to protect the loading and unloading assembly, such as a protection net or a light curtain.

[0321] In a preferred embodiment of the utility model, the transfer mechanism transfers the rough rod from the grinding assembly in a V-shaped clamping manner. On this basis, the grinding operation of the silicon rod is completed by fixing the silicon rod and reciprocating the grinding assembly. After the grinding is completed, the transfer mechanism transfers the finished square rod from the grinding station to the unloading assembly in a conventional 0° surface clamping manner. During this period, the posture of the silicon rod axis can be fine-tuned by the first adjustment assembly and the second adjustment assembly of the clamp assembly, thereby ensuring the clamping accuracy of the clamp assembly.

[0322] It can be seen that in the preferred embodiment of the present utility model, the grinding machine production line mainly has the following advantages:

[0323] (1) By designing the dual clamping spaces of the clamping jaw assembly differently, the transfer mechanism can better meet the transport operations for loading before grinding and unloading after grinding. Specifically, the clamping jaw assembly uses the first clamping space and the second clamping space to perform V-shaped clamping (rough rod before grinding) and 0° clamping (finished square rod after grinding) on ​​the silicon rod. In addition, by configuring an anti-falling assembly for the second clamping space corresponding to the 0° clamping, the risk of the finished square rod slipping or even falling off can be effectively prevented.

[0324] (2) The adjusting jaw assembly in the jaw assembly is configured with a first adjusting assembly capable of realizing longitudinal fine adjustment, and the jaw base, the fixed jaw assembly and the adjusting jaw assembly of the jaw assembly are integrally configured with a second adjusting assembly capable of realizing lateral fine adjustment. Based on this, the jaw assembly can be used to grasp silicon rods with certain deviations in size / posture, so the grinding machine production line has stronger adaptability to silicon rods.

[0325] (3) Through the setting of the transfer mechanism, it is possible to accommodate the transport operations of pre-grinding loading and post-grinding unloading for each grinding station in the grinding machine production line, which can significantly reduce the cost and floor space of the grinding machine production line. In addition, the transmission accuracy of the lateral moving component and the longitudinal moving component of the transfer mechanism is relatively high, so the transport reliability during pre-grinding loading and post-grinding unloading can be further guaranteed. In addition, when the clamping assembly is taking materials from the loading assembly or discharging materials to the lowering assembly, there will be no relative displacement between the silicon rod and the clamping assembly, thereby reducing the risk of silicon rod damage, thereby ensuring the operational reliability of the grinding machine production line for any grinding station.

[0326] (4) The loading and unloading components in the grinding machine production line are located on the same side of the gantry component, which improves the compactness of the equipment. For example, only one cantilever crane component is needed to realize the auxiliary loading and unloading operations for the grinding machine production line, saving the equipment cost.

[0327] (5) The clamping jaw assembly can measure the length of the silicon rod during loading (before clamping), saving the grinding cycle for any grinding station. During loading, the clamping jaw assembly can grasp and center the silicon rod through the cooperation of the threaded segments with opposite rotation directions at both ends of the screw nut mechanism, and the clamping jaw drive motor can directly calculate the cross-sectional size of the silicon rod while driving the screw nut mechanism, saving the grinding cycle for any grinding station.

[0328] (6) The grinding machine production line based on the utility model can better connect with the upstream processes such as squaring and the downstream processes such as slicing. On this basis, it is expected to achieve the integration of automated operations through multi-process assembly line operations and reduce manual intervention in multiple processes.

[0329] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
