[0002] In order to improve the efficiency of crystal rod slicing, the Chinese patent application number 202310258440.6 discloses a method and system for matching and cutting crystal rods. By retrieving the crystal rods stored in the vertical warehouse according to the length of the wire mesh on the machine, the crystal rods that match the length of the machine wire mesh are preferentially retrieved and cut, so as to reduce the number of wire mesh adjustments during the crystal rod slicing process and improve the slicing efficiency. In the current implementation process, the length of the crystal rod is mostly based on the length data provided by the crystal pulling end. However, after the crystal rod is solidified by bonding, the length of the crystal rod will change, resulting in a deviation between the length of the crystal rod stored in the system and the actual length, which makes the above-mentioned cutting method unable to be implemented smoothly. For this reason, it is necessary to design a new unloading logistics line, which can accurately measure the length of the crystal rod again during the transportation of the crystal rod, and bind the length of the crystal rod to the number of the crystal rod and store it in the system.

DETAILED DESCRIPTION

[0025] The embodiments of the present invention are described in detail below. Figure 1 、 Figures 5 to 7 , an embodiment of the present invention provides a material unloading logistics line of a die bonding and solidification line, comprising a plurality of crystal trays 100, a flow line 200, and a rod unloading robot. The crystal tray 100 is used to carry the crystal rod, the flow line 200 is used to transport the crystal tray 100 carrying the crystal rod to the vertical warehouse, and the rod unloading robot is arranged at the front end of the flow line 200, and is used to transport the crystal tray 100 carrying the crystal rod from the die bonding and solidification line to the flow line 200. The rod unloading robot is provided with a length measuring mechanism, which is used to measure the length of the crystal rod grasped by the rod unloading robot, and at least one label reader 210 is provided at the front end of the flow line 200. The label reader 210 is used to scan the label on the crystal rod to obtain the production number information of the crystal rod through the label. It can be understood that the label can be a QR code, barcode or string engraved on the crystal rod, or an NFC tag installed on the crystal rod, and the label reader 210 can be a barcode scanner, a camera or an NFC card reader.

[0026] The unloading logistics line of the crystal bonding and solidification line of the embodiment of the present invention can perform high-precision measurement of the length of the crystal ingot on the crystal tray 100 being transported through the length measuring mechanism on the unloading robot, and scan the label on the crystal ingot through the label reader 210 at the front end of the flow line 200 to obtain the production number information of the crystal ingot, so that the measured length of the crystal ingot and the production number information of the crystal ingot can be bound together and uploaded to the MES system for storage. This facilitates the retrieval of crystal ingots with matching lengths from the vertical library according to the wire mesh length when slicing the crystal ingot, thereby improving the efficiency of crystal ingot slicing. This logistics line can obtain the precise length of the crystal ingot after crystal bonding and solidification while transporting the crystal ingot, so that the wire mesh length of the machine can be accurately matched according to the measured crystal ingot length information when cutting the crystal ingot, reducing the number of adjustments to the wire mesh length, thereby improving the efficiency of crystal ingot slicing.

[0027] Reference Figures 5 to 7In this embodiment, the unloading manipulator uses a multi-axis robot arm to complete the transportation of the crystal ingot and the crystal tray 100. The end of the multi-axis robot arm is provided with a mechanical gripper 300, which is used to clamp the crystal tray 100 to avoid damage to the crystal ingot during transportation. At the same time, in order to further avoid damage to the crystal ingot during transportation, the length measuring mechanism should use a non-contact sensor to detect the length of the crystal ingot, such as by laser, ultrasonic wave or millimeter wave. Figure 5 and Figure 7 In this embodiment, the length measurement mechanism includes two laser ranging sensors 330, which are respectively mounted at both ends of a mechanical gripper 300 via two sensor brackets 331. The mechanical gripper 300 is provided with an escape hole 323 through which the laser light emitted by the laser ranging sensors 330 can pass. The two laser ranging sensors 330 respectively measure the distance between themselves and the end face of the crystal ingot, and the exact length of the crystal ingot is calculated based on the distance between the two laser ranging sensors 330.

[0028] Reference Figure 5 and Figure 6 In this embodiment, the mechanical gripper 300 includes an adapter substrate 310, two gripper brackets 320, and a gripper drive mechanism. The adapter substrate 310 is used to connect to the multi-axis robot arm. A connecting flange 311 is provided at the center of the upper surface of the adapter substrate 310. The connecting flange 311 is used to connect to the flange of the rotor of the DD motor at the end of the multi-axis robot arm. The two gripper brackets 320 are symmetrically slidably arranged at both ends of the adapter substrate 310. The upper ends of the gripper brackets 320 are slidably connected to the adapter substrate 310 via slide rails and can slide relative to the adapter substrate 310 in the longitudinal direction of the crystal support 100. The lower ends of the two gripper brackets 320 are both provided with L-shaped hook plates 321. The two hook plates 321 are used to hook the two ends of the crystal support 100 to achieve gripping of the crystal support 100. The two hook plates 321 are symmetrically arranged. The clamping mechanism is used to drive the two clamping brackets 320 to move toward each other to adjust the distance between the two hook plates 321 to achieve the clamping and release of the wafer holder 100. In this embodiment, the clamping mechanism includes two clamping cylinders, which are fixed to the transfer base plate 310 through two cylinder fixing plates 312 symmetrically arranged on the upper surface of the transfer base plate 310. The piston rods of the clamping cylinders are connected to the clamping brackets 320 on the same side. Figure 6 and Figure 7 In this embodiment, two sensor brackets 331 are respectively arranged on the outside of the two clamping jaw brackets 320, and the avoidance holes 323 are provided on the clamping jaw brackets 320. A rubber strip 322 is provided on the contact surface between the hook plate 321 and the side edge of the crystal holder 100 to form a buffer when clamping the crystal holder 100.

[0029] Reference Figures 1 to 4The flow line 200 includes a support frame and a conveyor belt mechanism. A transport channel 220 with a width matching that of the wafer tray 100 is located at the upper end of the support frame. The conveyor belt mechanism is located within the transport channel 220. Side guard plates 221 are located on both sides of the transport channel 220 to limit and guide the movement of the wafer tray 100. A tag reader 210 is mounted on the support frame via a reader bracket 211. It is understood that the conveyor mechanism 230 can use a conveyor belt, roller array, or conveyor chain to transport the wafer tray 100.

[0030] Reference Figure 1 and Figure 4 In this embodiment, the conveying mechanism 230 uses a chain to transport the crystal support 100. The conveying mechanism 230 includes two conveying chains 234, a driving shaft 231, a driven shaft 232 and a driving motor 235. The driving shaft 231 and the driven shaft 232 are respectively rotatably arranged at the two ends of the transportation channel 220, and the directions of the driving shaft 231 and the driven shaft 232 are perpendicular to the transportation direction. Two sprockets 233 are provided on the driving shaft 231 and the driven shaft 232. The spacing between the two sprockets 233 on the same shaft matches the width of the bottom surface of the crystal support 100. The two conveying chains 234 are arranged in parallel in the transportation direction in the transportation channel 220. The two ends of each conveying chain 234 are respectively sleeved on the sprockets 233 of the driving shaft 231 and the driven shaft 232, so that the spacing between the two conveying chains 234 also matches the width of the bottom surface of the crystal support 100. Refer to Figure 2 The output shaft of the drive motor 235 is connected to the drive shaft 231 via a speed reducer. The drive motor 235 rotates through the drive shaft 231, thereby driving the two conveyor chains 234 to rotate in a circular manner along the transport direction, thereby transporting the wafer tray 100. Multiple support beams are provided within the transport channel 220 to support the conveyor chains 234 and prevent them from being broken by the crystal ingot and wafer tray 100.

[0031] It is understood that each straight line of the flow line 200 can be composed of a set of conveyor chains 234, such as Figure 4 As shown, it can also be made up of multiple sets of conveyor chains 234, such as Figures 1 to 3 As shown. Figures 1 to 3 In the embodiment where the flow line 200 is composed of multiple conveying mechanism units, in order to facilitate the change of the transport direction of the wafer tray 100 during the flow process and make the splicing between the conveying mechanism units more flexible, the conveying mechanism 230 and the transport channel 220 are set on the support frame through a turning platform 240. The turning platform 240 is rotatably set on the support frame. A turning drive mechanism is set in the support frame. The turning drive mechanism can drive the turning platform 240 to turn horizontally, thereby changing the transport direction of the wafer tray 100. Figure 3In this embodiment, the steering drive mechanism includes a steering motor 242, a driving gear 241 and a driven gear 243. The driven gear 243 is sleeved on the rotating shaft of the steering platform 240. The output shaft of the steering motor 242 is connected to the driving gear 241 through a speed reducer, and the driving gear 241 is meshed with the driven gear 243. Figure 1 and Figure 2 In this embodiment, two buffer mechanisms 270 are further provided on the support frame. The two buffer mechanisms 270 are oriented vertically. The two buffer mechanisms 270 are respectively used to contact the side of the transport channel 220 when the turning platform 240 rotates horizontally 90 degrees and resets, so as to absorb the impact force when the transport channel 220 turns, so as to avoid the transport channel 220 carrying the crystal rod and the crystal support 100 from having a deviation in the stopping position due to excessive inertia after turning, and being unable to accurately dock with other conveying mechanism units. The buffer mechanism 270 can be a gas spring or a buffer pad.

[0032] Reference Figures 1 to 4 To ensure stable and accurate acquisition of the production number information of the crystal ingot, in this embodiment, two label readers 210 are installed at the front end of the flow line 200. The labels on the crystal ingots are QR codes, and correspondingly, the label readers 210 are barcode scanners. The two barcode scanners are installed on the support frame at a certain distance along the transportation direction of the crystal holder 100. When the crystal ingot moves along the transportation channel 220 driven by the conveyor mechanism 230, the two barcode scanners successively scan the QR code on the crystal ingot. This reduces the probability that one barcode scanner will not accurately read the information on the QR code on the crystal ingot due to external light interference, thereby improving the accuracy of obtaining the crystal ingot production number information.

[0033] Reference Figures 1 to 3 In this embodiment, several stoppers 260 and in-position sensors 250 are also provided within the transport channel 220. The in-position sensors 250 are used to detect whether the wafer holder 100 has reached a specific position, thereby controlling the triggering of the tag reader 210, the stoppers 260, or the steering platform 240 to achieve stable reading of the label on the ingot or to prevent the wafer holder 100 from moving outside the conveyor unit and obstructing the steering platform 240 from turning. The stoppers 260 are used to prevent the wafer holder 100 from moving along the transport channel 220 when necessary, allowing the wafer holder 100 to remain at a specific position. The in-position sensor 250 generally uses a photoelectric switch or a travel switch, and the material blocking mechanism 260 generally uses a material blocking cylinder. When the blocking pin of the material blocking cylinder is extended, the height of the blocking pin is higher than the bottom surface of the crystal support 100 in the transportation channel 220, thereby hindering the movement of the crystal support 100 and stopping the crystal support 100 at a specific position; when the blocking pin of the material blocking cylinder is retracted, the height of the blocking pin will be lower than the bottom surface of the crystal support 100 in the transportation channel 220, so that the material blocking mechanism 260 will not hinder the movement of the crystal support 100.

[0034] The working process of the unloading logistics line of the crystal bonding and solidification line of the embodiment of the present invention is as follows: the unloading robot clamps a crystal tray 100 carrying a crystal rod from the crystal bonding and solidification line each time, and measures the length of the crystal rod on the crystal tray 100 through two laser ranging sensors 330. After the measurement is completed, the crystal tray 100 is placed in the transportation channel 220 of the flow line 200; after the crystal tray 100 is placed in the transportation channel 220, the crystal tray 100 flows along the transportation channel 220 driven by the conveying mechanism 230, and the two barcode scanners scan and read the QR code on the crystal rod in turn. If the content read by the two barcode scanners is the same, the read content is bound to the measured length of the crystal rod and uploaded to the MES system to complete the measurement of the length of the crystal rod and data update.
