Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a transmission switching mechanism, a loading and unloading transmission device and a grinding device. Background Art
[0002] Silicon wafers are important materials for solar photovoltaic power generation. The manufacturing process of silicon wafers used in solar panels is divided into several steps: crystal pulling, truncation, squaring, grinding, slicing, etc. Crystal pulling is to generate cylindrical silicon rods in a crystal pulling furnace by chemical deposition, with a maximum length of 11 meters; truncation refers to cutting the silicon rods pulled out of the crystal into small sections of varying lengths (100-950mm); squaring refers to cutting the truncated silicon rods of different lengths into rectangular shapes; grinding refers to the process of grinding and polishing the four surfaces of the rectangular single crystal silicon rod after squaring with a grinding tool, and rounding the four edges.
[0003] In the process of squaring the silicon rod, in addition to the rectangular usable crystal rod, four edge materials with arc surfaces are also produced. In the traditional processing technology of single crystal silicon rods, the edge silicon materials are usually regarded as "waste materials". After being broken, they are returned to the furnace and re-pulled into single crystal silicon rods. The processing technology is complicated and the production efficiency is low. In order to further improve the efficiency of silicon rod processing, the existing edge material processing equipment obtains usable silicon blocks by squaring, cutting and grinding the edge materials again.
[0004] For large-scale processing systems such as edge material processing, multiple devices are often required to work in coordination. This involves the reasonable layout of multiple devices. It is necessary to meet the requirements of the material docking between the unloading station and the loading station of the processing equipment of two adjacent processes to meet the specific angle. This makes the layout between the equipment not flexible enough, and it is difficult to flexibly and quickly layout the processing system according to the characteristics of the factory.

[0044] In order to better understand the purpose, structure and function of the utility model, the grinding equipment of the utility model is further described in detail below in conjunction with the accompanying drawings.
[0045] The grinding device provided by the utility model is used to perform cutting operations on edge leather materials, such as Figure 1 As shown, Figure 1 a is the uncut silicon rod, Figure 1 b is the square stick in the middle and the four sides obtained after square root extraction. Figure 1 c is to cut off the end materials on both sides and the arc top material of the edge skin to obtain the long strip material in the middle. Figure 1 d is to cut off the long strip in the middle. Figure 1 e is the finished silicon block obtained after truncation and cutting.
[0046] The grinding device provided by the utility model is used for grinding rectangular silicon blocks to achieve the processing surface (such as the attached Figure 2 The device specifically comprises a loading and unloading transmission device, a turret clamping mechanism 4 and a sliding table grinding wheel mechanism 6.
[0047] like Figure 3-Figure 5 As shown, a plurality of clamping assemblies 5 are arranged on the turret clamping mechanism 4. By controlling the rotation of the turret clamping mechanism 4, the plurality of clamping assemblies 5 can be controlled to switch between a plurality of different stations to cooperate in completing the grinding process and loading and unloading operations of the silicon block. The plurality of stations include at least one loading and unloading station and at least one grinding station; the loading and unloading transmission device is arranged at the loading and unloading station to complete the loading and unloading of the silicon block at the loading and unloading station; the sliding table grinding wheel mechanism 6 is arranged on the grinding station, and the sliding table grinding wheel mechanism 6 reciprocates along the radial direction of the turret clamping mechanism 4 on the grinding station to perform grinding operations on the silicon block.
[0048] The grinding equipment provided by the embodiment of the utility model completes the conversion of silicon blocks at different workstations by clamping the silicon block through the turret clamping mechanism 4 and rotating it, so that continuous preparation and continuous processing of silicon blocks can be realized, and the processing efficiency is high. In addition, the vertical turret form is adopted, which occupies a small area, and the silicon block processing output per unit area of the equipment is higher.
[0049] The loading and unloading transmission device, turret clamping mechanism 4 and slide grinding wheel mechanism 6 of the grinding equipment of the utility model are introduced respectively below. It should be noted that the grinding equipment of the utility model can be used not only for grinding silicon blocks, but also for processing other materials. Therefore, silicon block grinding is not used as a basis for limiting the protection scope of the grinding equipment provided by the utility model.
[0050] Furthermore, since each station is arranged around the turret clamping mechanism (circumferential direction), the utility model defines a coordinate system for each station to describe each component. Fig.12 For example, the utility model takes the vertical direction of each workstation as the third direction of the current workstation, that is, the z-axis direction, and the radial direction of the central turret 41 of the current workstation as the second direction of the current workstation, that is, the y-axis direction, and the tangent direction of the central turret 41 of the current workstation as the first direction of the current workstation, that is, the x-axis direction.
[0051] 1. Loading and unloading transmission device:
[0052] The loading and unloading transmission device provided in the embodiment of the utility model comprises a transmission switching mechanism 1, a material storage device 2 and a transfer centering mechanism 3.
[0053] like Figure 6-Figure 8As shown, the transmission and transfer mechanism 1 provided in the embodiment of the utility model includes a first transmission component 11 and a second transmission component 12. The first transmission component 11 can be rotatably arranged between a first preset station and the second transmission component 12, and the end of the second transmission component 12 away from the first transmission component 11 is arranged at the second preset station.
[0054] In a specific embodiment of the present invention, the first preset station is a material unloading station of an upstream device docked with the grinding device, and the second preset station is a material loading station of the grinding device. Since the material transmission directions between the first preset station and the second preset station may be different, the present invention adopts a transmission transfer mechanism 1 that can transmit materials between two stations in the same transmission direction, and can also transmit materials between two stations in different transmission directions.
[0055] That is, the material transmission direction between the first preset station and the second preset station can be at any angle, and the material can be transferred between the first preset station and the second preset station by controlling the rotation of the first transmission component 11, so that the material can be transferred between the first preset station and the second preset station through the first transmission component 11 and the second transmission component 12, thereby making it unnecessary to consider that the transmission direction of the unloading station of the upstream processing equipment and the loading station of the downstream processing equipment must be the same when the two equipment are laid out as a whole, thereby improving the layout flexibility between different equipment in the same processing system and improving the utilization rate of the factory space.
[0056] In a specific embodiment of the present invention, when the transmission and transfer mechanism 1 is arranged at the loading end of the grinding equipment, that is, when it is docked with the storage device 2, the first preset station is the unloading end of the upstream edge skin cutting equipment, and the second preset station is the storage device 2. The storage device 2 can receive incoming materials from any direction of the edge skin cutting equipment. The edge skin cutting equipment and the grinding equipment do not have to be limited to the transmission direction of loading and unloading, making the layout of different equipment more flexible. Therefore, the transmission and transfer mechanism 1 of the embodiment of the present invention can make the installation of the entire edge skin material processing system more flexible. As shown in the attached figure Figure 7 and attached Figure 8 As shown, the transmission and transfer mechanism 1 provided in the embodiment of the utility model can achieve 0° and 90° docking, and can also achieve docking at other angles.
[0057] It can be understood that the transfer mechanism 1 provided in the embodiment of the utility model can also be arranged at the unloading end of the grinding equipment, or between two processing equipment of other large-scale processing systems, to complete the material transfer between processing equipment with different material transmission directions.
[0058] Furthermore, the first transmission component 11 and the second transmission component 12 are both transmission belts, and the delivery of materials is completed by controlling the transmission belts to rotate along the transmission direction. Figure 6As shown, the second transmission assembly 12 includes a second transmission belt and a second belt driving assembly, and the second belt driving assembly drives the second transmission belt to rotate.
[0059] Specifically, the first transmission component 11 in the embodiment of the utility model includes a rotating drive support 111 and a first transmission belt component arranged on the rotating drive support 111. The first transmission belt component is driven to rotate as a whole by controlling the rotation of the rotating drive support 111. The first transmission belt component includes a first transmission belt and a first belt drive component. The material placed on the first transmission belt is driven to move by controlling the rotation of the first transmission belt.
[0060] Furthermore, in one embodiment of the utility model, a preset avoidance distance is maintained between the first transmission component 11 and the second transmission component 12 in the transmission direction of the second transmission component 12 to avoid interference between the first transmission component 11 and the second transmission component 12. Specifically, the first transmission component 11 can be prevented from interfering with the second transmission component 12 during rotation. Since the first transmission component 11 is rotatable, in order to avoid interference between the first transmission component 11 and the second transmission component 12 during rotation, a first preset distance can be set between the first transmission component 11 and the second transmission component 12. The distance should be less than the length of the transmitted material to ensure that the material can be smoothly transferred between the first transmission component 11 and the second transmission component 12.
[0061] In another embodiment of the utility model, a first translation drive assembly (not shown in the drawings) is provided below the rotation drive support 111, and the first translation drive assembly controls the first transmission assembly 11 to reciprocate and translate along the transmission direction of the second transmission assembly 12, so as to avoid interference between the first transmission assembly 11 and the second transmission assembly 12 by controlling the translation of the first translation drive assembly. Specifically, when the first transmission assembly 11 rotates, the first translation drive assembly is controlled to translate in a direction away from the second transmission assembly 12, so as to avoid interference between the first transmission assembly 11 and the second transmission assembly 12. As an alternative embodiment, when the second transmission assembly 12 needs to rotate, the second transmission assembly 12 is controlled to move in a direction away from the second transmission assembly 12 as a whole, so as to avoid interference with the second transmission assembly 12. When the first transmission assembly 11 finishes rotating, the first transmission assembly 11 can be controlled to move in a direction close to the second transmission assembly 12, so as to avoid the transmission material from falling during the delivery process between the first transmission assembly 11 and the second transmission assembly 12.
[0062] Furthermore, a second translation drive assembly (not shown in the drawings) is provided below the rotation drive support 111. The second translation drive assembly controls the first transmission assembly 11 to reciprocate in the vertical direction. While allowing the first transmission assembly 11 to adapt to materials of different transmission heights, it can also avoid interference between the first transmission assembly 11 and the second transmission assembly 12 and other equipment during rotation by raising the first transmission assembly 11.
[0063] Furthermore, a first bracket 112 is provided under the first transmission component 11, and a second bracket 121 is provided under the second transmission component 12. The height of the first bracket 112 is lower than that of the second bracket 121, so that the transmission height of the first transmission component 11 can be switched between above, flush with, and below the second transmission component 12.
[0064] Furthermore, a liftable anchor device 13 is provided below the first bracket 112 and the second bracket 121 , and the lifting and lowering of the entire conveying and switching mechanism 1 is controlled by controlling the lifting and lowering of the anchor device 13 to adapt to different heights of the grinding equipment.
[0065] In a specific embodiment of the present invention, one end of the second transmission component 12 is arranged at the loading station and / or unloading station of the grinding device, and the first transmission component 11 is arranged at the unloading end of the upstream processing equipment (edge skin cutting integrated machine) of the grinding device and / or the loading end of the downstream processing equipment (silicon block pasting equipment). It can be understood that the first transmission component 11 can also be arranged at the loading end or unloading end of the grinding device. Since the first transmission component 11 is rotatable, the grinding device can adapt to incoming or unloading materials in different directions (such as Figure 7 , Figure 8 As shown), the entire edge material processing system is more adaptable to the spatial environment.
[0066] The transmission and switching mechanism 1 provided in the embodiment of the utility model is not only applicable to the grinding equipment of the utility model, but also applicable to various material processing systems. By being arranged between various processing equipment in the system, the layout of various equipment in the processing system is more flexible, and the processing system has lower requirements for factory space.
[0067] like Figure 9-11 As shown, the storage device 2 provided in the embodiment of the utility model is arranged at the feeding end of the grinding equipment, and includes a transverse transmission device 22 and a storage bin 21, wherein one end of the transverse transmission device 22 is docked with the transmission switching mechanism 1 to receive the silicon blocks transmitted by the transmission switching mechanism 1, and the other end extends to the inside of the grinding equipment to cooperate with the transfer centering mechanism 3 to complete the feeding and centering of the silicon blocks. The transverse transmission device 22 passes through the inside of the storage bin 21, and the storage bin 21 is provided with a plurality of groups of storage positions 211 that can be raised and lowered, and the storage and discharge of materials in the storage bin 21 are realized by controlling the lifting and lowering of the storage positions 211.
[0068] Further, the transverse transmission device 22 transmits the material to the storage bin 21 along the first direction, and the storage bin 21 is provided with a plurality of storage positions 211, and the plurality of storage positions 211 reciprocate along the third direction to transfer the material on the transverse transmission device 22 to the storage position 211 or transfer the material in the storage position 211 to the transverse transmission device 22;
[0069] Furthermore, the transverse transmission device 22 includes a transmission belt and a driving assembly for controlling the rotation of the transmission belt. After receiving the silicon blocks, the transverse transmission device 22 controls the rotation of the transmission belt to drive the silicon blocks to be transmitted to the storage bin 21 .
[0070] Furthermore, the storage bin 21 includes a plurality of oppositely arranged storage racks 213, and two opposite storage racks 213 are respectively arranged on both sides of the transverse transmission device 22 to form a storage position 211. As shown in the accompanying drawings, the transverse width of the material placed on the transverse transmission device 22 is greater than the width of the transverse transmission device 22 (the width of the transmission belt), so that both ends of the material protrude from the transverse transmission device 22 and are located above the storage racks 213. When material storage is required, the storage racks 213 on both sides are controlled to rise at the same time, and the storage racks 213 drive the material to leave the transverse transmission device 22 to complete the material storage; when material discharge is required, the storage racks 213 on both sides are controlled to descend at the same time, so that the material is placed on the transverse transmission device 22 again, and at this time, the transverse transmission device 22 is controlled to drive the material to move horizontally to the loading station to complete the material loading.
[0071] The material storage device 2 provided in the embodiment of the utility model can be used as a material buffer of the entire automated production line to store silicon blocks of the upstream production line, so that the automation level of the entire system is higher. In addition, since the material storage bin 21 is arranged perpendicular to the horizontal transmission device 22, the space of the horizontal transmission device will not be occupied when storing materials. While realizing the storage of silicon blocks, the entire material storage device 2 occupies a smaller area, making the equipment structure more compact.
[0072] Furthermore, the storage bin 21 provided in the embodiment of the utility model further includes a lifting assembly 212 disposed on both sides of the transverse transmission device 22, and the storage rack 213 is evenly disposed on the lifting assembly 212. By controlling the two relative lifting assemblies 212 to synchronously reciprocate along the third direction, the relatively disposed storage rack 213 is driven to synchronously reciprocate along the third direction. The lifting assembly 212 can specifically be a lifting chain assembly, and the storage rack 213 is fixedly disposed on the lifting assembly 212. In order to maintain stability, two or more lifting assemblies 212 are disposed on one side of the transverse transmission device 22, and the storage rack 213 is evenly fixed on the lifting assembly 212, so that the storage rack 213 remains stable during the lifting movement.
[0073] Furthermore, the storage bin 21 provided in the embodiment of the utility model further includes a lifting drive assembly 214, which is used to drive the lifting assembly 212 to rise or fall. Specifically, the lifting drive assembly 214 includes a first driven gear and a second driven gear meshing with each other, and a chain transmission assembly is respectively sleeved on the first driven gear and the second driven gear, and the other end of the chain transmission assembly is respectively connected to the lifting assemblies 212 on both sides of the transverse transmission device 22, so as to drive the lifting assemblies 212 on both sides to achieve lifting movement at the same time through a set of motor drive, thereby ensuring the synchronous lifting of the storage rack 213 and avoiding the material from tipping over due to the asynchronous movement of the storage racks 213 on both sides during the rising or falling process.
[0074] The material storage device provided in the embodiment of the utility model is not only applicable to the grinding equipment of the utility model, but also applicable to the incoming material buffer device of other processing equipment. For the processing system of edge materials, since the edge materials of the previous process will produce multiple silicon blocks at one time after cutting, the grinding equipment cannot process multiple silicon blocks produced at one time at the same time during the grinding process. Therefore, the material storage device 2 makes the grinding equipment more adaptable to the upstream processing equipment, without manual participation in material preparation, so that the whole system has a higher degree of automation.
[0075] like Figure 12-Figure 15 As shown, the transfer and centering mechanism 3 provided by the embodiment of the utility model is arranged at the loading and unloading station, and includes a transfer component and a centering component. The transfer component includes a space transfer device and a grabbing execution device at the end of the space transfer device, so as to drive the grabbing execution device to transfer materials at the loading station through the space transfer device. The centering component includes a relatively arranged jaw assembly, and the jaw assembly performs a centering operation on the material by synchronous relative movement along a first direction. Specifically, the jaw assembly performs a centering operation on the silicon block placed on the clamping assembly 5 at the loading station.
[0076] In a specific embodiment of the utility model, the loading and unloading of the grinding equipment are located at the same station, so the transfer assembly can complete the loading and unloading of the silicon block at the same time. After the transfer assembly places the silicon block on the second clamping head of the clamping assembly 5 of the turret clamping mechanism 4, the centering assembly performs a centering clamping operation on the silicon block so that the center of the silicon block coincides with the center of the clamping assembly 5, that is, the material center coincides with the material clamping center of the loading station, so as to facilitate the subsequent grinding operation.
[0077] Furthermore, the transfer and centering mechanism 3 also includes a support assembly 31, one end of the support assembly 31 is fixed at the loading station, and the other end is connected to the spatial transfer device of the transfer assembly; the support assembly 31 is also provided with a centering assembly sliding guide rail 36 extending along the third direction, and the clamping assembly also includes a centering clamping jaw base plate 310, one side of the centering clamping jaw base plate 310 is slidably connected to the centering assembly sliding guide rail 36, and the other side of the centering clamping jaw base plate 310 is connected to the clamping jaw assembly.
[0078] Specifically, a centering screw extending along the third direction is provided on the support assembly 31, and a centering bolt is provided on the centering jaw base plate 310. The centering bolt is connected to the centering screw to control the rotation of the centering assembly screw to control the reciprocating motion of the entire jaw assembly along the third direction.
[0079] In the embodiment of the utility model, the spatial transfer device is coaxially designed with the centering component, and the materials at the loading station are clamped, transferred and centering are performed in coordination, which saves space at the loading station and makes the device structure compact. The centering component as a whole can reciprocate along the third direction, which is convenient for centering and clamping materials of different thicknesses and heights.
[0080] In a specific embodiment of the utility model, the support assembly 31 is a support frame extending along the third direction, one end of which is fixed on the base 7 of the grinding equipment, and the other end is connected to the first direction beam 32 of the space transfer device. The space transfer device provided by the embodiment of the utility model includes a first direction beam 32 and a first direction driving assembly. A third direction vertical beam 33 is slidably connected to the first direction beam 32, and a third direction driving assembly is arranged on the third direction vertical beam 33. The first direction driving assembly drives the third direction vertical beam 33 to reciprocate on the first direction beam 32. A suction cup assembly is connected to the end of the third direction vertical beam 33. The third direction driving assembly drives the suction cup assembly to reciprocate on the third direction vertical beam 33. The suction cup assembly serves as a grabbing execution device of the transfer assembly to absorb materials.
[0081] Specifically, a first direction screw and a screw driving motor for driving the first direction screw to rotate are provided on the first direction horizontal beam 32, and the third direction vertical beam 33 is connected to the first direction screw by bolts, and the rotation direction of the first direction screw is controlled by the screw driving motor, thereby realizing the reciprocating motion of the third direction vertical beam 33 in the first direction.
[0082] Furthermore, a vertical beam cylinder is provided on the vertical beam 33 in the third direction, and a suction cup assembly is provided at the end of the vertical beam cylinder. By controlling the telescopic movement of the vertical beam cylinder, the reciprocating movement of the suction cup assembly in the third direction is realized.
[0083] The spatial transfer device provided by the embodiment of the utility model can clamp silicon blocks and quickly transfer them between the storage device 2 and the loading station due to its simple structure of spatial motion control, thereby improving the overall operation efficiency of the equipment.
[0084] In a specific embodiment of the present utility model, since the suction cup assembly needs to place the silicon block on the clamping head of the clamping assembly 5 of the turret clamping mechanism 4, in order to avoid interference with the clamping assembly 5 of the turret clamping mechanism 4, the suction cup assembly provided in the embodiment of the present utility model includes a second direction extension plate 34, one end of the second direction extension plate 34 is connected to the end of the third direction vertical beam 33, and the other end is connected to at least one suction cup 35. The second direction extension plate 34 maintains a preset extension distance between the suction cup 35 and the end of the third direction vertical beam 33, thereby avoiding interference between the transfer assembly and the clamping assembly 5 on the turret clamping mechanism 4.
[0085] Furthermore, the clamping jaw assembly provided in the embodiment of the utility model includes a centering jaw 37 and a synchronous drive assembly which are relatively arranged along a first direction. The synchronous drive assembly can drive the two centering jaws 37 to move synchronously relative to each other along the first direction, thereby realizing the centering operation of the silicon block on the loading station, so that the center of the silicon block coincides with the clamping center of the loading station.
[0086] Specifically, the synchronous drive assembly of the embodiment of the utility model can be a device such as a gear rack structure, a ball screw structure, etc. that can realize the synchronous reverse movement of the two centering jaws 37. In the specific embodiment of the utility model, the synchronous drive assembly includes a centering drive motor, a bidirectional lead screw and a centering guide rail, the bidirectional lead screw and the centering guide rail are arranged in parallel along the first direction, the two centering jaws 37 are respectively installed on the positive thread segment and the negative thread segment of the bidirectional lead screw, and are respectively slidably arranged on the centering guide rail, the centering drive motor is connected to the bidirectional lead screw, and the bidirectional lead screw is driven by the centering drive motor to rotate, driving the relatively arranged centering jaws 37 to synchronously reverse movement, the centering jaws 37 of the utility model synchronously reverse movement, so that the stroke of each movement of the relatively arranged centering jaws 37 is the same, thereby ensuring the accuracy of the centering operation.
[0087] Furthermore, the clamping jaw assembly is also provided with a centering probe assembly 38, as shown in the attached Fig.15 As shown, the centering probe assembly 38 is arranged at the front side of the centering jaw 37 and is used synchronously with the centering jaw 37. When the centering jaw 37 approaches the material, the centering probe assembly 38 first detects the position of the side of the material, so that the centering jaw 37 can control the movement speed according to the distance from the material. When the centering probe assembly 38 does not contact the material, the centering jaw 37 is controlled to move quickly. When the centering probe assembly 38 contacts the material, the centering probe is controlled to retract and the centering jaw 37 is controlled to perform the centering operation slowly, thereby improving the centering clamping efficiency and preventing the centering jaw 37 from bumping against the material due to excessive movement. In addition, by simultaneously detecting the position of the material through the centering probe assemblies 38 on both sides, the distance between the relative sides of the material can be obtained, thereby determining the grinding allowance of the material.
[0088] Furthermore, the centering probe assembly 38 includes a centering probe and a probe driving assembly, and the probe driving assembly drives the centering probe to reciprocate along the first direction to control the centering probe to protrude or retract the clamping surface of the centering clamp 37. When the centering probe protrudes from the clamping surface of the centering clamp 37, the position of the material is detected and measured, and when the probe retracts from the clamping surface, the centering clamp 37 is controlled to move to complete the centering clamping operation of the silicon block, so as to avoid the probe affecting the centering clamping operation of the centering clamp 37.
[0089] It can be understood that in addition to driving the centering probe to protrude or retract the clamping surface of the centering jaw 37 through the probe driving assembly, the centering probe can also be connected to the centering jaw 37 through an elastic member. When the centering jaw 37 performs the centering clamping operation, the centering probe retracts under the action of the material pressure. When the centering jaw 37 releases the material, the centering probe extends out of the clamping surface of the centering jaw 37 under the action of the elastic force, so as to facilitate the measurement and detection of the material.
[0090] Furthermore, the centering jaw 37 provided in the embodiment of the present invention includes a clamping block disposed on the opposite side of the centering jaw 37, and the clamping surface of the clamping block maintains a preset length and width to accommodate clamping of materials of different sizes.
[0091] Furthermore, the centering assembly provided in the embodiment of the utility model further includes a second direction driving assembly 39, the centering jaw bottom plate 310 is connected to the second direction driving assembly 39, and the second direction driving assembly 39 controls the centering jaw bottom plate 310 to drive the jaw assembly as a whole to reciprocate in the second direction. By controlling the centering assembly to reciprocate in the second direction, the centering jaw 37 as a whole is driven to move in a direction close to the material.
[0092] Specifically, the second direction driving assembly 39 is a rack arranged on the clamping jaw assembly and extending along the second direction, and a rack driving assembly fixed on the base. The gear at the driving end of the rack driving assembly is engaged with the rack on the clamping jaw assembly, and the rack is driven to reciprocate along the second direction by rotating the driving gear.
[0093] Furthermore, the centering assembly also includes a centering calibration device, and the positional relationship between the centering calibration device and the loading station is relatively fixed. The centering probe assembly 38 determines the material clamping center of the loading station by detecting the centering calibration device.
[0094] The control process of the loading and unloading transmission device of the utility model embodiment is briefly introduced below:
[0095] S1, the transmission and transfer mechanism 1 transfers the material to the storage device 2;
[0096] S2, the storage bin 21 of the storage device 2 stores the material to the storage position 211;
[0097] S3. When the grinding equipment needs to be loaded with materials, the storage bin 21 transfers the materials to the transverse transmission device 22 of the storage device 2, and the transverse transmission device 22 transfers the materials to the material grabbing position of the transfer component;
[0098] S4, the grabbing execution device of the transfer component grabs the material and then the spatial transfer device transfers the material to the loading and unloading station;
[0099] S5. The centering component detects the position and size of the materials at the loading and unloading stations and completes the centering displacement operation of the materials;
[0100] S6. When the grinding equipment needs to unload materials, the grabbing execution device of the transfer component grabs the materials at the loading and unloading stations, and then the spatial transfer device transfers the materials to the unloading end.
[0101] The above steps are the complete operation flow of the loading and unloading material transmission device. The centering operation of the material by the centering component in step S5 specifically includes:
[0102] S51, the turret clamping mechanism 4 drives the first clamping assembly to rotate to the loading and unloading station, and the transfer assembly clamps the material and places it on the second clamping head of the first clamping assembly;
[0103] S52, the centering component performs a centering operation on the first processing side surface of the material, and detects the first processing side surface through a centering detection probe to determine the processing allowance of the first processing side surface;
[0104] S53, the second chuck drives the material to rotate as a whole so that the second processing side is arranged opposite to the centering component, the centering component performs a centering operation on the second processing side of the material, and the second processing side is detected by the centering detection probe to determine the processing allowance of the second processing side.
[0105] The loading and unloading transmission device provided in the embodiment of the utility model can not only receive materials from different transmission directions, but also store the materials through the storage device 2, and simultaneously complete the loading and unloading transmission of the materials, the centering operation of the materials and the size detection. The structure of the whole system is compact and the degree of automation is higher, which simplifies the workflow for subsequent processing operations and simplifies the structural complexity of the equipment.
[0106] 2. Turret clamping mechanism 4:
[0107] The turret clamping mechanism 4 provided in the embodiment of the utility model can be rotatably arranged on the base 7, including a central turret 41 and a plurality of clamping components 5 arranged in the circumferential direction of the central turret 41. The central turret 41 can rotate along its central axis. In the specific embodiment of the utility model, the central axis of the central turret 41 is a rotation axis perpendicular to the direction of the base 7. The central turret 41 rotates along the central axis to drive each clamping component 5 to rotate between different stations. The corresponding base 7 is provided with a station corresponding to the clamping component 5 on the turret clamping mechanism. Therefore, after a silicon block is clamped and centered once, multiple processing stations can simultaneously perform rough grinding, fine grinding and other grinding operations on the silicon block, so as to achieve the purpose of processing multiple silicon blocks simultaneously in one processing cycle, thereby improving the grinding efficiency of the silicon block.
[0108] like Figure 16-Figure 19 As shown, in a specific embodiment of the utility model, the turret clamping mechanism 4 includes a central turret 41 and three clamping assemblies 5 evenly arranged in the circumferential direction of the central turret 41, that is, the angle between two adjacent clamping assemblies 5 is 120°, and corresponding to the turret clamping mechanism 4, a loading and unloading station, a rough grinding station and a fine grinding station are arranged on the base 7 of the grinding equipment, and the angle between each station is also 120°. Therefore, after the silicon block completes the centering and clamping operation at the loading and unloading station, the rough grinding and fine grinding can be completed in sequence by controlling the rotation of the turret clamping mechanism 4, and finally rotated to the loading and unloading station to complete the unloading of the silicon block by the transfer centering mechanism 3.
[0109] Furthermore, a rotation drive assembly 42 is provided on the base 7, and the rotation drive assembly 42 drives the central turret 41 to rotate as a whole. A rotation gear is provided at one axial end of the central turret 41, and the turret clamping mechanism 4 also includes a gear drive assembly meshed with the rotation gear, and the gear drive assembly drives the rotation gear to rotate, so as to drive the central turret 41 to rotate as a whole. In a specific embodiment of the utility model, the rotation gear is provided at the bottom end of the central turret 41, and the gear drive assembly includes a driving gear provided on the base 7 and meshed with the rotation gear, and a gear drive motor located in the base that drives the driving gear to rotate. The utility model controls the rotation angle of the central turret 41 by means of gear drive, which can ensure the rotation accuracy of the central turret 41, and further ensure the processing accuracy of silicon block grinding.
[0110] Further, a slip ring bracket 43 and a slip ring assembly are provided at one axial end of the central turret 41, the slip ring bracket 43 fixes the slip ring assembly at a preset position of the central turret 41, the fixed end of the slip ring assembly is connected to a preset external power source, the external power source is connected to the rotating end of the slip ring assembly through the inside of the slip ring assembly, and the rotating end of the slip ring assembly is connected to the power device inside the turret clamping mechanism 4, so as to transmit the external power source to the power device inside the turret clamping mechanism 4. The external power source can be a power source, a gas source, or an oil source, and the power device can be not only a rotating power device, but also other devices suitable for gas or oil.
[0111] In a specific embodiment of the utility model, the turret clamping mechanism 4 includes a slip ring bracket 43 and a slip ring assembly at the top, the slip ring assembly is fixed above the central turret 41 of the turret clamping mechanism 4 through the slip ring bracket 43, and the slip ring assembly transports electricity, gas, and lubricating oil to the inside of the central turret 41. The utility model uses an electric slip ring device to provide energy and power for the electricity, gas, and lubrication equipment of the central turret 41, and also avoids the line winding problem caused by continuously providing energy and power to the electrical equipment of the rotating material loading unit.
[0112] The turret clamping mechanism 4 of the embodiment of the utility model rotates along the central axis through the central turret 41 to drive each clamping assembly 5 to rotate between different workstations, thereby realizing simultaneous processing of multiple materials within one working cycle and improving the processing efficiency of the equipment.
[0113] like Figure 19-22 As shown, the clamping assembly 5 on the turret clamping mechanism 4 includes a first clamping head assembly 51 and a second clamping head assembly 52 which are arranged opposite to each other along the axial direction of the central turret 41. The first clamping head assembly 51 and the second clamping head assembly 52 reciprocate along the axial direction of the central turret 41 to clamp or release the material.
[0114] It should be noted that the clamping assembly 5 provided in the embodiment of the utility model can be applied not only to the turret clamping mechanism 4 of the grinding equipment, but also to other rotating frames or moving frames.
[0115] Furthermore, the first chuck assembly 51 includes a clamping chamber and a first chuck 511. A clamping drive assembly 513 is arranged in the clamping chamber. The clamping chamber forms an internally enclosed space, so that the clamping chamber isolates the clamping drive assembly 513 from the external environment, thereby preventing dust and water mist generated during the equipment processing from entering the clamping drive assembly 513.
[0116] Furthermore, the clamping chamber includes a cover body 541 and a clamping drive assembly 513 in the cover body 541, the cover body 541 is connected to the side wall of the central turret 41, the first clamp 511 extends through the first opening on the cover body 541 to the outside of the cover body 541, and the clamping drive assembly 513 drives the first clamp 511 to reciprocate along the axial direction of the central turret 41. The utility model uses a clamping chamber to protect the clamping drive assembly 513 in the cover body 541, avoids the influence of silicon powder and water mist on the clamping drive assembly 513 during the processing process, and ensures the operation stability of the equipment.
[0117] Furthermore, the first chuck assembly 51 also includes a first chuck bracket 512 and a first chuck 511. A clamping slide rail is arranged in the cover body 541 of the clamping chamber. Specifically, the clamping slide rail is arranged on the side wall of the central turret 41. One end of the first chuck bracket 512 is slidably connected to the clamping slide rail, and the other end extends along the radial direction of the central turret 41 away from the central brick tower 41 and is connected to the first chuck 511. The clamping drive assembly 513 drives the first chuck bracket 512 to reciprocate on the clamping slide rail to drive the first chuck 511 located at the end of the first chuck bracket 512 to reciprocate along the clamping direction.
[0118] Furthermore, the clamping drive assembly 513 also includes a clamping screw and a clamping screw driving motor. The first chuck bracket 512 is connected to the clamping screw. The clamping screw driving motor drives the clamping screw to rotate and drives the first chuck bracket 512 to reciprocate along the axial direction of the clamping screw.
[0119] In a specific embodiment of the utility model, the first chuck 511 is arranged at the upper end of the central turret 41, the second chuck 521 is arranged at the lower end of the central turret 41, and the silicon block is placed on the second chuck 521. The clamping and loosening of the silicon block are achieved by controlling the lifting and reciprocating motion of the first chuck 511, thereby ensuring the stable placement of the silicon block on the second chuck 521, avoiding the movement of the second chuck 521 during the clamping process to affect the position of the silicon block on the second chuck 521, and improving the stability during the clamping operation.
[0120] Furthermore, since the first clamp 511 needs to reciprocate at the first opening of the clamping chamber, in order to prevent silicon powder and water mist from entering the cover body 541 through the first opening, the clamping chamber provided by the embodiment of the utility model further includes a clamp accordion cover 542, which is a closed annular cover body, one axial end of which is connected to the first clamp bracket 512, and the other end is connected to the first opening. The clamp accordion cover 542 prevents dust and water mist from entering the cover body 541 through the first opening while ensuring the reciprocating motion of the first clamp 511, further improving the protection level of the clamping chamber.
[0121] Furthermore, a second opening 543 is provided on the cover body 541, and the second opening 543 is connected to an external air source to blow air into the clamping chamber, so that the inner cavity of the clamping chamber is in a slightly positive pressure state. The slightly positive pressure state increases the resistance of external dust and water mist to enter the clamping chamber, further improving the protection level of the clamping chamber.
[0122] Furthermore, the second chuck 521 includes a second chuck bracket 522 and a second chuck 521, one end of the second chuck bracket 522 is connected to the side wall of the rotating frame, and the other end extends in the radial direction of the rotating frame away from the rotating frame, and the second chuck 521 is connected to the end of the second chuck bracket 522.
[0123] Furthermore, the second chuck 521 of the embodiment of the utility model can rotate around the central axis of the second chuck 521 to drive the material placed on the second chuck 521 to rotate as a whole, so as to facilitate the rotation of the material through the second chuck 521 to cooperate with the processing device to perform processing operations on different sides of the material.
[0124] Specifically, the second chuck assembly 52 also includes a chuck rotation drive assembly, which includes a chuck rotation motor 524 and a chuck bearing 523. The second chuck 521 is connected to the rotating shaft of the chuck rotation motor 524 through the chuck bearing 523. The second chuck 521 is driven to rotate by the chuck rotation motor 524 to drive the material on the second chuck 521 to rotate.
[0125] Furthermore, the first clamp assembly 51 further includes a driven bearing 515 and a floating clamp 514, and the floating clamp 514 is connected to the first clamp 511 through the driven bearing 515, so that the floating clamp 514 rotates with the second clamp 521. By arranging the floating clamp 514 on the first clamp 511, the utility model can make the clamp assembly 5 clamp the material and drive the material as a whole to rotate along the central axis of the clamp assembly 5, so as to avoid the material from being offset on the clamp assembly during the rotation process, and keep the center of the material coincident with the center of the clamp assembly 5.
[0126] When grinding a silicon block, it is necessary to grind the silicon block in the directions of 0° and 90°. In order to ensure that the silicon block can be rotated while being clamped, the utility model adopts a method in which the second chuck 521 actively rotates the first chuck 511 passively rotates. While rotating the silicon block, the position of the silicon block will not be offset, thereby ensuring that the clamping center always coincides with the center of the silicon block, thereby ensuring the grinding accuracy.
[0127] like Fig. 22As shown, when performing the grinding operation, the grinding wheel 624 rotates at a high speed between the first chuck 511 and the second chuck 521, so the clamping assembly 5 needs to provide a grinding avoidance space for the grinding wheel 624. Specifically, the utility model connects the central turret 41 through the first chuck bracket 512 and the second chuck bracket 522, so that the clamping center of the first chuck 511 and the second chuck 521 maintains a certain distance from the side wall of the central turret 41, providing a processing avoidance space for the grinding wheel to perform the grinding operation.
[0128] Furthermore, the first clamp 511 has a preset first axial length in the axial direction, and the second clamp 521 has a second axial length in the axial direction, so as to provide a processing avoidance space when the clamping assembly 5 clamps the material.
[0129] In a specific embodiment of the present invention, since the size of the silicon block is small, the size of the grinding wheel used to grind the silicon block is larger than the size of the silicon block. Therefore, the present invention provides an escape space for the grinding wheel during the grinding operation by extending the axial length of the first chuck 511 and the second chuck 521.
[0130] The turret clamping mechanism 4 provided in the embodiment of the utility model is not only applicable to the grinding equipment of the utility model, but also applicable to other processing equipment. The turret clamping mechanism 4 can cooperate to complete simultaneous processing operations at different workstations, making the entire equipment structure compact, improving processing efficiency, and ensuring stable operation of the equipment.
[0131] 3. Slide grinding wheel mechanism 6
[0132] In the embodiment of the utility model, a slide grinding wheel mechanism 6 is provided at both the rough grinding station and the fine grinding station of the grinding equipment, and the grinding operation of the silicon block is realized by controlling the grinding wheel assembly 62 of the slide grinding wheel mechanism 6 to reciprocate along the radial direction of the central turret 41.
[0133] like Figure 23-Figure 27 As shown, the slide grinding wheel mechanism 6 provided by the embodiment of the utility model includes a slide feed guide rail 63 arranged along the second direction of the grinding station, a grinding wheel slide 61 slidably connected to the slide feed guide rail 63, and a slide feed drive assembly, two grinding wheel assemblies 62 are relatively arranged on the grinding wheel slide 61, and the slide feed drive assembly drives the grinding wheel slide 61 to reciprocate along the second direction to approach or move away from the clamping assembly 5.
[0134] Furthermore, a grinding wheel feed guide rail and a grinding wheel feed drive assembly are relatively arranged on the grinding wheel slide 61 along the first direction of the grinding station, and the grinding wheel assemblies 62 are slidably arranged on the grinding wheel feed guide rails. The grinding wheel feed drive assembly drives the grinding wheel assembly 62 to reciprocate along the first direction so that the two relative grinding wheel assemblies 62 are close to or away from each other.
[0135] The slide grinding wheel mechanism 6 provided in the embodiment of the utility model controls the grinding wheel assembly 62 to be close to the clamping assembly 5 as a whole through the grinding wheel slide 61, ensuring synchronous feeding of the left and right grinding wheels during high-speed grinding, and the grinding process is more stable.
[0136] Furthermore, when the grinding wheel assembly 62 performs a grinding operation, the grinding wheel 624 rotates at a high speed and feeds along the grinding direction, which may cause the grinding wheel to overheat. If the grinding wheel 624 is in such a working condition for a long time, defects may appear on the surface, which eventually affects the quality of the surface of the ground silicon block. Therefore, a corresponding cooling system is designed for the grinding wheel in the embodiment of the utility model.
[0137] Specifically, the grinding wheel assembly 62 includes a grinding wheel drive assembly 623, a grinding wheel 624 and a spindle unit, wherein the spindle unit includes a rotating spindle (not shown in the drawings) and a spindle housing 621 coaxially arranged with the rotating spindle, wherein the rotating spindle is wrapped in the spindle housing 621 inside the spindle housing 621, and the rotating spindle and the spindle housing 621 are relatively independent, and the rotating spindle maintains high-speed rotation while the spindle housing remains relatively stationary, therefore, the grinding wheel drive assembly 623 drives the rotating spindle to rotate, so as to drive the grinding wheel 624 connected to the end of the rotating spindle to rotate, and a grinding wheel cooling assembly 625 is provided at one end of the spindle housing 621, and the grinding wheel cooling assembly 625 cools the grinding wheel.
[0138] Furthermore, the grinding wheel cooling assembly 625 includes a liquid inlet and a nozzle extending to the side of the grinding wheel 624. The liquid inlet is connected to an external coolant, and the coolant is sprayed onto the grinding wheel 624 through the nozzle. The grinding wheel cooling assembly 625 provided in the embodiment of the utility model can effectively reduce the temperature of the grinding wheel 624 and improve the grinding efficiency and grinding quality by spraying the coolant on the grinding wheel alone.
[0139] Furthermore, since silicon powder and water mist are generated during the grinding process, the slide grinding wheel mechanism 6 of the embodiment of the utility model further includes a grinding wheel drive chamber, a grinding wheel drive assembly 623 is arranged inside the grinding wheel drive chamber, one end of the spindle unit extends into the grinding wheel drive chamber to connect the rotating spindle with the grinding wheel drive assembly 623, and the other end extends out of the grinding wheel drive chamber and is connected to the grinding wheel at the end. The grinding wheel drive chamber includes a grinding wheel cover 641, which protects each drive assembly in an internal closed space to prevent water mist and silicon powder from affecting the drive assembly.
[0140] Furthermore, an accordion protective cover 642 is provided on the spindle unit outside the grinding wheel driving chamber, one end of the accordion protective cover 642 is fixedly connected to the grinding wheel driving chamber, and the other end is connected to the end of the spindle housing 621. The accordion protective cover 642 prevents water mist and silicon powder from entering the grinding wheel driving chamber through the gap of the spindle unit, further ensuring the stable operation of the equipment.
[0141] Furthermore, the grinding wheel driving chamber is provided with an air inlet 643, so that air is blown into the grinding wheel driving chamber through the air inlet 643. The air inlet 643 is connected to an external air source, so that the grinding wheel driving chamber presents a slightly positive pressure state, providing resistance to the entry of external dust and water mist, and playing a secondary auxiliary sealing role.
[0142] Furthermore, the grinding wheel driving assembly 623 includes a grinding wheel rotation driving motor and a tensioning belt. The rotating shaft of the grinding wheel rotation driving motor is connected to the rotating main shaft through the tensioning belt. The grinding wheel rotation driving motor drives the tensioning belt to rotate to drive the rotating main shaft to rotate.
[0143] Furthermore, the grinding wheel drive assembly 623 also includes a belt adjusting device, which includes a belt shaft mounting plate and a plurality of oblong holes on the belt shaft mounting plate. The rotating shaft at one end of the tensioning belt is installed in the oblong hole through a bolt assembly, and the other end of the tensioning belt is connected to the rotating spindle. The tension of the tensioning belt is adjusted by adjusting the position of the bolt assembly in the oblong hole.
[0144] The utility model drives the synchronous belt through the motor, the synchronous belt drives the spindle unit, and the spindle unit drives the grinding wheel 624, and finally realizes the high-speed rotation of the grinding wheel 624. In this device, a belt tensioning device is designed to adjust the tension of the belt to achieve the purpose of stable operation. The whole structure is compact and has high space utilization.
[0145] In addition, the grinding wheel drive assembly of the embodiment of the utility model further includes a calibration probe assembly 65, which is used to detect the position of the material to be ground. The calibration probe assembly 65 includes a calibration probe and a calibration probe drive assembly, and the calibration probe drive assembly drives the calibration probe to reciprocate along the first direction to protrude or retract from the grinding surface of the grinding wheel 624. The calibration probe assembly 65 and the turret clamping mechanism 4 constitute a processing position correction system of the processing equipment provided in the embodiment of the utility model, and the processing position correction system is further introduced below.
[0146] 4. Processing position correction system
[0147] like Fig.26 As shown, in the embodiment of the utility model, a calibration device 54 is further provided on the clamping assembly 5. In order to prevent the rotation error of the central turret 41 during the rotation process from affecting the grinding accuracy of the silicon block, the embodiment of the utility model introduces a calibration probe on the grinding wheel assembly 62 and a position calibration assembly on the clamping assembly 5. The rotation angle of the central turret 41 can be calibrated to further improve the grinding accuracy of the silicon block.
[0148] The present invention comprises a turret clamping mechanism 4, a clamping assembly 5 and a calibration device 54 on the turret clamping mechanism 4, a calibration probe assembly 65 on the slide grinding wheel mechanism 6 and a positioning device 71 on the grinding station, which together constitute a processing position correction system provided by an embodiment of the present invention.
[0149] It should be noted that the position correction system can be applied not only to the grinding equipment of the embodiment of the utility model, but also to other processing equipment with similar structure to the utility model, such as a slide mechanism with a structure similar to the slide grinding wheel mechanism 6, and a corresponding processing component is arranged on the slide mechanism. By arranging a corresponding calibration probe component 65 on the processing component, the processing position correction of the above embodiment can be realized.
[0150] Specifically, the system includes a base 7, a turret clamping mechanism 4 and a slide mechanism (corresponding to the slide grinding wheel mechanism of the grinding equipment), at least one processing station is arranged on the base 7, a positioning device 71 and a slide mechanism are arranged at the processing station, the slide mechanism includes a processing component and a calibration probe component 65, the slide mechanism reciprocates along the second direction of the processing station so that the processing component performs processing operations on the material at the processing station, a clamping component 5 is arranged on the turret clamping mechanism 4, a calibration device 54 is arranged on the clamping component 5, the turret clamping mechanism 4 drives the clamping component 5 to rotate to the processing station, and the calibration probe component 65 respectively detects the positioning device 71 and the calibration device 54 to determine the position offset of the clamping component 5 relative to the processing station.
[0151] Furthermore, the calibration device 54 is a position calibration reference plate, the positioning device 71 is a position positioning reference plate, and the calibration probe assembly 65 respectively detects the positions of the position positioning reference plate and the position calibration reference plate in the first direction of the processing station, and determines the displacement difference between the position positioning reference plate and the position calibration reference plate in the first direction of the processing station, so as to determine the position difference of the clamping assembly 5 on the turret clamping mechanism 4 from the processing station.
[0152] Furthermore, the processing position correction system provided by the embodiment of the utility model also includes a transfer centering mechanism 3 provided at the loading and unloading station provided by the aforementioned embodiment, so as to complete the centering of the material center and the clamping center of the clamping assembly 5 during loading through the transfer centering mechanism 3, which serves as the basis for subsequent processing correction. Since it has been described in detail in the aforementioned embodiment, it will not be repeated here.
[0153] The following is a detailed description of the correction method of the processing position correction system of the processing equipment in the above embodiment, which includes:
[0154] S1, the turret clamping mechanism 4 drives the clamping assembly 5 to rotate to the processing position corresponding to the clamping assembly 5;
[0155] S2, the slide mechanism at the processing station moves along the radial direction of the turret clamping mechanism 4 close to the clamping assembly 5, so as to detect the positioning device 71 and the calibration device 54 respectively through the calibration probe assembly 65, and determine the position offset of the clamping assembly 5 relative to the current processing station;
[0156] S3. Control the processing component of the slide mechanism to move along the first direction to compensate for the position offset of the clamping component at the current processing station.
[0157] Among them, controlling the processing component of the slide mechanism to move in the first direction to compensate for the position offset of the clamping component at the current processing station is specifically to control the processing component of the slide mechanism as a whole to move the corresponding position offset in the opposite direction of the position offset in the first direction of the current processing station, at this time, the distance between the two processing components on the slide mechanism remains fixed, and the distance between the two processing components is the target processing distance of the processing side of the material to be processed. In addition, the centering operation at the loading and unloading station included in the method has been described in the aforementioned embodiment, and it may also specifically include:
[0158] S01, the turret clamping mechanism 4 drives the first clamping assembly to rotate to the loading and unloading station, and the transfer assembly transfers the material to the first clamping assembly;
[0159] S02, the centering assembly at the loading and unloading station moves along the radial direction of the turret clamping mechanism close to the first clamping assembly, and detects the material position through the centering probe assembly 38;
[0160] S03, the centering component moves synchronously relative to the first direction of the loading and unloading station to perform a centering operation on the material;
[0161] S04. The centering probe assembly 38 of the centering assembly extends out to detect the relative distance between the two processed sides of the material.
[0162] The processing position correction system provided by the embodiment of the utility model has the following advantages: after the turret clamping mechanism drives the clamping assembly 5 to rotate to the processing station, the calibration probe assembly 65 on the slide mechanism respectively detects the positioning device 71 of the processing station and the calibration device 54 on the clamping assembly 5, and determines the position offset of the clamping assembly 5 at the current processing station, so as to compensate for the position offset of the clamping assembly 5 by controlling the overall movement of the processing assembly along the first direction, and compensate for the control accuracy of the rotation angle of the turret clamping mechanism 4, thereby improving the processing accuracy of the processing equipment.
[0163] 6. Knife repair system
