Description

Technical Field

[0001] The present invention relates to the technical field of ingot processing, and particularly to an automatic conveying system for ingot products. Background Art

[0002] In the semiconductor and photovoltaic industries, as a key raw material, the efficient and stable conveying of ingot products is an important link to ensure the continuous operation of subsequent processes such as slicing. Ingot products are usually bonded by an ingot carrier and an ingot. During the conveying process, it is necessary to not only meet the high-efficiency requirements of automated production but also cope with the feeding requirements in case of emergencies, such as equipment failures and temporary shortages of raw materials.

[0003] There are generally two major problems in the existing ingot product conveying systems:

[0004] First, there is a lack of manual feeding interface. Traditional conveying systems mostly rely on a single automated feeding system (such as a double-speed chain conveyor line, a robotic arm, etc.). Although continuous conveying can be achieved, when the ingot products are exhausted at the upstream feeding end, the conveyor line fails, or the production plan needs to be adjusted temporarily, the system cannot quickly access the manual feeding operation, resulting in production interruption and insufficient flexibility. Although a pure manual sorting system has a certain degree of flexibility, its efficiency is low and it is difficult to meet the continuity requirements of large-scale industrial production.

[0005] Second, shortages are likely to occur during the conveying and distribution process. When conveying ingot products to the next processing step (such as a slicing machine), the existing systems usually adopt direct conveying or simple buffering methods, lacking an efficient buffering and distribution mechanism. When the demand frequency of the ingot products by the subsequent processing equipment is high or there is mixed-line production of multiple product models, the simple buffering structure cannot store a sufficient number of ingot products, resulting in the processing equipment stopping due to waiting for feeding, seriously affecting production efficiency.

[0006] Therefore, an automatic conveying system for ingot products is provided to solve the above technical problems. Summary of the Invention

[0007] The purpose of the present invention is to provide an automatic conveying system for ingot products in view of the deficiencies of the prior art, so as to solve the technical problems of the lack of a manual feeding interface in the existing ingot product conveying system and the easy occurrence of shortages when conveying and distributing ingot products to the next process.

[0008] To achieve the above purpose, the technical solution of the present invention is as follows:

[0009] An automatic conveying system for a crystal bar product, comprising at least two first double-speed chain conveying lines. An artificial feeding mechanism for manually feeding the crystal bar product is correspondingly arranged at the discharging end of each first double-speed chain conveying line. The system further comprises a material distributing and transferring mechanism connected to the ends of a number of artificial feeding mechanisms at the same time. The artificial feeding mechanism can convey the crystal bar product manually fed or the crystal bar product conveyed by the first double-speed chain conveying line to the material distributing and transferring mechanism; an artificial feeding station is arranged beside the artificial feeding mechanism.

[0010] The system further comprises a number of buffer feeding mechanisms for buffering a plurality of crystal bar products. The material distributing and transferring mechanism is connected to the number of buffer feeding mechanisms through a second double-speed chain conveying line, and the material distributing and transferring mechanism, the second double-speed chain conveying line and the buffer feeding mechanisms are connected in series in sequence.

[0011] The beneficial effects of the present invention: During operation, the two first double-speed chain conveying lines continuously convey the crystal bar products at a preset speed. The crystal bar products move along the first double-speed chain conveying line from its feeding end to the discharging end. After reaching the discharging end of the first double-speed chain conveying line, they are received by the artificial feeding mechanism at the end, and then the artificial feeding mechanism continues to convey the crystal bar products to convey them onto the material distributing and transferring mechanism. When the system detects that the crystal bar products at the feeding end of the first double-speed chain conveying line are conveyed out or the first double-speed chain conveying line needs to be repaired, the staff places the crystal bar products on the artificial feeding mechanism at the artificial feeding station, and then directly conveys them to the material distributing and transferring mechanism through the artificial feeding mechanism to achieve timely replenishment of materials. Under the action of the artificial feeding mechanism, a feeding system mainly based on automation and supplemented by manual labor is constructed, which not only retains the continuity of automated production but also endows the flexibility of manual intervention; compared with the traditional single automatic feeding system or pure manual sorting system, the present conveying system realizes the diversification of feeding methods through the organic combination of automatic conveying and manual intervention, and can still perform feeding processing in case of emergencies.

[0012] In addition, different first double-speed chain conveying lines uniformly convey the crystal bar products onto the material distributing and transferring mechanism, and then operate the material distributing and transferring mechanism to transfer the crystal bar products one by one, transfer them onto the second double-speed chain conveying line for continuous conveying, and convey and distribute them to the corresponding buffer feeding mechanisms through the second double-speed chain conveying line for buffering. While buffering, the crystal bar products will be carried to the subsequent mechanism for processing one by one. By setting the buffer feeding mechanism, a plurality of crystal bar products can be stored at one time, enabling continuous feeding without running out of materials, and improving the processing efficiency.

[0029] The following describes in detail an automatic conveying system for a crystal bar product of the present invention with reference to the accompanying drawings.

[0030] As Figure 1 shown, an embodiment of an automatic conveying system for a crystal bar product of the present invention includes at least two first double-speed chain conveying lines 1. The first double-speed chain conveying lines 1 are used to convey crystal bar products 100 for feeding. An artificial loading mechanism 2 for manually loading crystal bar products 100 is correspondingly arranged at the discharge end of each first double-speed chain conveying line 1. The system further includes a material distribution and transfer mechanism 3 that is simultaneously connected to the ends of a number of artificial loading mechanisms 2. The artificial loading mechanism 2 can convey the crystal bar products 100 manually loaded or conveyed by the first double-speed chain conveying lines 1 to the material distribution and transfer mechanism 3.

[0031] Two first-speed chain conveyor lines 1 continuously convey the ingot products 100 at a preset speed. The ingot products 100 move along the first-speed chain conveyor line 1 from its feeding end to the discharging end. After reaching the discharging end of the first-speed chain conveyor line 1, they are received by the manual loading mechanism 2 at the end, and then the manual loading mechanism 2 continues to convey the ingot products 100 to convey them to the material distribution and transfer mechanism 3. There is a manual loading station 27 beside the manual loading mechanism 2. When the system detects the need for manual loading (such as when the ingot products 100 placed at the feeding end of the first-speed chain conveyor line 1 are conveyed out, or the first-speed chain conveyor line 1 needs to be repaired), the staff places the ingot products 100 on the manual loading mechanism 2 at the manual loading station 27, and then the manual loading mechanism 2 directly conveys the ingot products 100 to the material distribution and transfer mechanism 3 to achieve timely replenishment of materials. Under the action of the manual loading mechanism 2, a feeding system with automatic as the main and manual as the auxiliary is constructed, which not only retains the continuity of automated production but also endows the flexibility of manual intervention. Compared with the traditional single automatic feeding system (lacking a manual replenishment interface) or pure manual sorting system, this conveying system realizes the diversification of feeding methods through the organic combination of automatic conveying and manual intervention, and can still perform feeding processing in case of emergencies.

[0032] This conveying system also includes several buffer loading mechanisms 5 for buffering multiple ingot products 100. The material distribution and transfer mechanism 3 is connected to several buffer loading mechanisms 5 through a second-speed chain conveyor line 4, and the material distribution and transfer mechanism 3, the second-speed chain conveyor line 4, and the buffer loading mechanisms 5 are connected in series in sequence to form a chain-type conveying structure. Each buffer loading mechanism 5 is respectively connected to different ingot processing production lines (not shown in the figure). The ingot processing production line is used to perform slicing processing on the ingot products 100, that is, to process the ingots into silicon wafers, and silicon wafers of different sizes or models can be processed according to different ingot processing production lines. Different first-speed chain conveyor lines 1 uniformly convey the ingot products 100 to the material distribution and transfer mechanism 3, and then operate the material distribution and transfer mechanism 3 to transfer the ingot products 100 one by one, transfer them to the second-speed chain conveyor line 4 for continuous conveying. Before the transfer, it is necessary to scan and identify the ingot products 100. After identifying the size or model that the ingot products 100 need to be processed subsequently, they are conveyed and distributed to the corresponding buffer loading mechanism 5 through the second-speed chain conveyor line 4 for buffering. While buffering, the ingot products 100 will be carried to the corresponding ingot processing production line for slicing processing one by one. By setting the buffer loading mechanism 5, multiple ingot products 100 can be stored at one time, and in the slicing process, continuous feeding can be realized without the situation of material shortage, improving the processing efficiency.

[0033] In addition, two or more second double-speed chain conveyor lines 4 can be provided, and the feeding ends of the two second double-speed chain conveyor lines 4 are both connected to the material distribution and transfer mechanism 3. By operating the material distribution and transfer mechanism 3, the ingot products 100 can be respectively transported and distributed onto different second double-speed chain conveyor lines 4 to achieve the effect of material distribution.

[0034] As Figures 2 - 3 shown, the manual loading mechanism 2 includes a support frame 21 and a lifting table 22 that is movably arranged up and down on the support frame 21. The lifting table 22 is equipped with a first conveying module 23 for supporting and conveying the ingot product 100. When the lifting table 22 moves to the apex, the initial end of the first conveying module 23 is connected to the discharging end of the corresponding first double-speed chain conveyor line 1, and the terminal end of the first conveying module 23 is connected to the material distribution and transfer mechanism 3. After the first double-speed chain conveyor line 1 transports the ingot product 100 onto the first conveying module 23, it is then transported to the material distribution and transfer mechanism 3 for transfer and conveyance, and finally conveyed to the designated buffer loading mechanism 5 through the second double-speed chain conveyor line 4 for buffering. In addition, when manual loading is required, the lifting table 22 is controlled to move downward to the bottom point. At this time, after the operator places the ingot product 100 on the first conveying module 23 at the manual loading station 27, the lifting table 22 is controlled to move upward to the apex to reconnect it to the material distribution and transfer mechanism 3, and the manually loaded ingot product 100 is transported to the material distribution and transfer mechanism 3.

[0035] Furthermore, the manual loading mechanism 2 further includes a control mechanism 24 for controlling the up and down movement of the lifting table 22 and a support crossbar 25 installed at the top of the support frame 21. A handling mechanism 26 for transporting the ingot product 100 placed at the manual loading station 27 onto the first conveying module 23 is horizontally movably arranged on the support crossbar 25.

[0036] As Figure 4As shown in the figure, the control mechanism 24 includes a right-angle steering gear 241 (model can be T-type corner converter XCT2) installed on the lifting platform 22. Coaxial rotating shafts 242 are arranged on the two laterally arranged output shafts of the right-angle steering gear 241. The two rotating shafts 242 on both sides are laterally arranged and their axes are perpendicular to the moving direction of the lifting platform 22. The right-angle steering gear 241 is used to control the two rotating shafts 242 on both sides to rotate in the same direction simultaneously. A pair of racks 244 with a length direction parallel to the moving direction of the lifting platform 22 are installed on the support frame 21. The two racks 244 on both sides are respectively close to different rotating shafts 242. First gears 243 are arranged at the mutually remote ends of the two rotating shafts 242 on both sides. The two first gears 243 on both sides are respectively engaged with different racks 244. It also includes a driving motor 245. The output shaft of the driving motor 245 is connected to the vertically arranged output shaft of the right-angle steering gear 241. By operating the driving motor 245, the right-angle steering gear 241 is driven to control the two rotating shafts 242 on both sides to rotate in the same direction simultaneously. Since the racks 244 are fixedly arranged, in cooperation with the two first gears 243 on both sides, the lifting platform 22 is driven to move up and down on the support frame 21.

[0037] As Figure 5 shown in the figure, the handling mechanism 26 includes a movable seat 261 that is horizontally movably arranged on the support cross bar 25. A fixed frame 263 is installed on the movable seat 261. A vertically arranged first cylinder 265 and a lifting frame 264 that can move up and down are arranged on the fixed frame 263. The end of the telescopic rod of the first cylinder 265 is fixedly arranged with the lifting frame 264. The telescopic rod of the first cylinder 265 expands and contracts to drive the lifting frame 264 to move up and down. An installation frame 266 is arranged at the bottom of the lifting frame 264, and a number of vacuum suction cups 267 for sucking the ingot product 100 are installed on the installation frame 266. When the staff pushes the movable seat 261 to move horizontally on the support cross bar 25, a number of vacuum suction cups 267 are driven to move horizontally together. When it moves to the manual loading station 27 and is placed directly above the ingot product 100, the first cylinder 265 is operated to control the lifting frame 264 to move downward, so that a number of vacuum suction cups 267 are in contact with the ingot product 100, and then vacuum is pumped to suck the ingot product 100. Finally, by controlling the upward and horizontal movement of the vacuum suction cups 267, the ingot product 100 can be transported to the first conveying module 23.

[0038] In this embodiment, in order to improve the accuracy of handling, the movable seat 261 is equipped with a first sensor 268 for sensing its position, and is also equipped with a second cylinder 269 with a telescopic rod arranged upward. A stop block 2610 for generating friction after contacting the support cross bar 25 is installed at the end of the telescopic rod of the second cylinder 269. The movable seat 261 moves horizontally. When the first sensor 268 senses the manual loading station 27 or the first conveying module 23, the second cylinder 269 operates to control the stop block 2610 to contact the top surface of the support cross bar 25 to generate a frictional force, and the frictional force is such that the staff cannot push the movable seat 261 to move. When the vacuum suction cup 267 sucks the ingot product 100 or places the ingot product 100 on the first conveying module 23, the stop block 2610 is controlled to separate from the support cross bar 25, so that the vacuum suction cup 267 is accurately placed at the designated handling position and unloading position.

[0039] In addition, a chute is formed inside the support cross bar 25, and the movable seat 261 is equipped with a roller set 262 slidably arranged in the chute; by providing the chute and the roller set 262, the resistance when pushing the vacuum suction cup 267 to move horizontally is reduced.

[0040] As Figures 6 - 7As shown in the figure, the material distribution and transfer mechanism 3 includes a first transfer module 31 and a second transfer module 32 that are respectively connected to different manual feeding mechanisms 2. The number of transfer modules is determined by the number of manual feeding mechanisms 2. The first transfer module 31 and the second transfer module 32 have the same structure and the same operating mode. After they operate, they can be respectively connected to different second double-speed chain conveyor lines 4. Among them, the first transfer module 31 includes a fixed plate 311 and a rotating plate 312 rotatably arranged on the fixed plate 311. The axis of rotation of the rotating plate 312 is arranged vertically, and a second conveying module 313 for supporting and conveying the ingot product 100 is installed on the rotating plate 312. In order to drive the rotation of the rotating plate 312, a toothed ring 314 with its center point coaxially arranged with the axis of rotation is installed on the rotating plate 312, and a first servo motor 315 is installed on the fixed plate 311. A second gear 316 meshing with the toothed ring 314 is installed on the output shaft of the first servo motor 315. The initial state of the second conveying module 313 is to be connected to the end of the first conveying module 23. After the first conveying module 23 conveys the ingot product 100, it is received by the second conveying module 313. Subsequently, the first servo motor 315 is operated. Under the transmission of the second gear 316 and the toothed ring 314, the rotating plate 312 is driven to rotate, and the second conveying module 313 rotates together to adjust the orientation. When it is adjusted to be connected to the corresponding second double-speed chain conveyor line 4, the second conveying module 313 is operated to convey the ingot product 100 to the second double-speed chain conveyor line 4, realizing the transfer of the ingot product 100. Finally, the ingot product 100 is conveyed to the corresponding buffer feeding mechanism by the second double-speed chain conveyor line 4 for buffering, realizing the distribution of the ingot product 100.

[0041] As Figures 8 - 10As shown in the figure, the buffer loading mechanism 5 includes a support platform 51 and a support conveying part 52 installed on the support platform 51. At both ends of the support conveying part 52, a third conveying module 53 and a fourth conveying module 54 are respectively connected, and the two can be respectively connected to different second double-speed chain conveying lines 4 or to the same second double-speed chain conveying line 4. After the second double-speed chain conveying line 4 conveys the ingot product 100 onto the third conveying module 53 or the fourth conveying module 54, it is finally conveyed onto the support conveying part 52. Transversely arranged linear drive modules 55 are installed on both the third conveying module 53 and the fourth conveying module 54. The length direction of the linear drive module 55 is perpendicular to the conveying direction of the support conveying part 52. On the movable ends of each linear drive module 55, a material blocking block 56 for blocking the ingot product 100 onto the support conveying part 52 is installed. After the ingot product 100 is conveyed onto the support conveying part 52 by the third conveying module 53 or the fourth conveying module 54, the linear drive modules 55 on both sides operate simultaneously to control the material blocking blocks 56 to be respectively placed on both sides of the ingot product 100, so as to accurately block the ingot product 100 onto the support conveying part 52, facilitating subsequent handling and buffering.

[0042] Furthermore, the buffer loading mechanism 5 of the present invention further includes a support plate 57 disposed beside the support conveying part 52. There are a pair of support plates 57 and both are in a vertical posture. A lifting plate 58 that can move up and down is arranged between the two support plates 57. A transverse movement frame 59 that can move horizontally in a direction approaching or departing from the support conveying part 52 is arranged on the lifting plate 58. At least three placing blocks 511 for placing the ingot product 100 are installed on the tops of the two support plates 57. The placing blocks 511 on the same side are arranged in an equidistant array along the movement direction of the transverse movement frame 59, and the positions of the placing blocks 511 on both sides correspond to each other. The transverse movement frame 59 is in a U shape, and a number of supporting blocks 510 for supporting the ingot product 100 are installed at both top ends. The number of supporting blocks 510 on the same side is the same as the number of placing blocks 511 arranged on the same support plate 57, and the positions of the equidistant arrays of the supporting blocks 510 correspond to the positions of the equidistant arrays of the placing blocks 511.

[0043] Specifically, after the ingot product 100 is accurately conveyed onto the support conveying part 52, first control the lifting plate 58 to move downward, thereby driving the transverse movement frame 59 and several supporting blocks 510 to move upward together, so that the top surface of the supporting block 510 is lower than the top surface of the support conveying part 52. At this time, the lifting plate 58 stops moving. Then control the transverse movement frame 59 to move towards the support conveying part 52, so as to drive the first supporting block 510 (the supporting block 510 closest to the support conveying part 52) placed at both ends of the transverse movement frame 59 to be placed at both ends of the support conveying part 52 and directly below the ingot product 100. Then control the lifting plate 58 to move upward. After moving until the top surface of the supporting block 510 is higher than the top surface of the support conveying part 52, the ingot product 100 can be lifted to separate it from the support conveying part 52. Then control the transverse movement frame 59 to move away from the support conveying part 52. After moving the ingot product 100 directly above the first placing block 511 (the placing block 511 closest to the support conveying part 52) placed on the support plate 57, then control the lifting plate 58 to move downward, driving the ingot product 100 to move downward together to place it on the first placing block 511 for caching, thus completing the handling process of the ingot product 100. However, repeat the above handling process. When the first supporting block 510 is directly below the ingot product 100 to be handled, the second supporting block 510 is exactly directly below the ingot product 100 placed on the first placing block 511. While the first supporting block 510 lifts the ingot product 100 placed on the support conveying part 52, the second supporting block 510 lifts the ingot product 100 placed on the first placing block 511. While the first supporting block 510 transports the ingot product 100 to the first placing block 511, the second supporting block 510 transports the ingot product 100 to the second placing block 511. Repeat the above operations to achieve the alternating handling of the ingot product 100, so that at least three ingot products 100 can be placed and cached on the two support plates 57.

[0044] In this embodiment, in order to control the transverse movement frame 59 to move horizontally on the lifting plate 58 towards or away from the support conveying part 52, the lifting plate 58 is provided with a second servo motor 513, and a screw rod 512 with an axis parallel to the movement direction of the transverse movement frame 59 is installed on the output shaft of the second servo motor 513. A threaded sleeve 514 is arranged in a threaded connection with the screw rod 512, and the threaded sleeve 514 is fixedly arranged with the transverse movement frame 59. By operating the second servo motor 513 to drive the screw rod 512 to rotate, in cooperation with the threaded connection with the threaded sleeve 514, the transverse movement frame 59 can be controlled to move horizontally on the lifting plate 58 towards or away from the support conveying part 52.

[0045] In addition, a number of guide blocks 515 are provided on both support plates 57. On both sides of the lifting plate 58 close to the support plate 57, guide rails 516 slidably arranged with the guide blocks 515 are provided. The guide rails 516 are slidably arranged up and down on the guide blocks 515. Under the action of the arranged guide rails 516 and guide blocks 515, the lifting plate 58 is more stable during the up and down movement. Moreover, guide rails 516 and guide blocks 515 can also be provided between the lifting plate 58 and the transverse movement frame 59 to make the transverse movement frame 59 more stable when moving horizontally on the lifting plate 58.

[0046] To control the up and down movement of the lifting plate 58, a first slide rail 517 with a length direction parallel to the movement direction of the transverse movement frame 59 is provided on the support table 51. A sliding frame 518 is slidably arranged horizontally on the first slide rail 517, and a number of wedge-shaped blocks 519 are installed on the sliding frame 518; on the bottom surface of the lifting plate 58, mounting blocks 520 with the same number as the number of the wedge-shaped blocks 519 are installed. On each mounting block 520, a rolling wheel 521 for cooperating with the wedge-shaped block 519 to apply an upward thrust to the lifting plate 58 is rotatably arranged. The wedge-shaped block 519 is formed with an inclined side for contacting the surface of the rolling wheel 521. When the sliding frame 518 drives a number of wedge-shaped blocks 519 to move horizontally together, the inclined sides on each wedge-shaped block 519 contact different rolling wheels 521 respectively. During the continuous horizontal movement, the rolling wheel 521 rolls on the inclined side of the wedge-shaped block 519 and jacks up the rolling wheel 521, thereby applying an upward thrust to the lifting plate 58 and pushing the lifting plate 58 to move upward. When the sliding frame 518 drives a number of wedge-shaped blocks 519 to separate from the rolling wheels 521, the lifting plate 58 automatically moves downward under the action of its own gravity. In addition, a third air cylinder 522 (as Figure 8 shown) for pushing the sliding frame 518 to slide is also installed on the support table 51. The end of the telescopic rod of the third air cylinder 522 is fixedly arranged with the sliding frame 518.

[0047] After the ingot products 100 are alternately carried to the last storage block 511, they need to be flipped and transported. First, they are flipped and then transported to a specified position to facilitate the subsequent transportation of the ingot products 100 to the ingot processing production line for slicing processing.

[0048] As Figure 11As shown in the figure, the buffer loading mechanism 5 further includes a pedestal bearing 523 and a reduction gearbox 525 disposed on the support table 51. A turning seat 524 is arranged between the pedestal bearing 523 and the reduction gearbox 525. One end of the turning seat 524 is rotatably connected to the pedestal bearing 523, and the other end is fixedly connected to the output shaft of the reduction gearbox 525. The axis of rotation of the turning seat 524 is arranged horizontally and perpendicular to the moving direction of the transverse movement frame 59. The support table 51 is equipped with a third servo motor 526 whose output shaft is connected to the input shaft of the reduction gearbox 525.
