Description

Technical Field

[0001] This invention relates to the field of crystal rod processing technology, and in particular to a crystal rod transfer trolley, a crystal rod processing and storage system, and a crystal rod transportation method. Background Technology

[0002] In precision manufacturing fields such as photovoltaic silicon wafers and semiconductor chips, crystal ingots are core raw materials. Their production and processing are highly continuous and precise, requiring multiple steps and processes. Crystal ingot transfer trolleys, as key transfer and temporary storage equipment between these processes, play a crucial role in these core stages. For example, after crystal ingots are drawn, they are typically placed on a transfer trolley for natural cooling. Then, they are transferred to a trolley for trolling to correct dimensional parameters such as roundness and perpendicularity. After trolling, the ingots are transported again by the transfer trolley to a cutting machine for cutting. Finally, the cut ingots are placed back on the trolley and transferred to a temporary crystal ingot storage warehouse for storage and recording.

[0003] However, when the crystal ingots are cut and transported to the temporary storage warehouse, information such as the ingot's mass and length needs to be entered into the warehouse's system. Currently, this is done by using a dedicated weighing device to weigh the ingots, which is then recorded by staff and entered into the system during storage. Although the length information after cutting can be read by the cutting machine, there are multiple carts transporting ingots to the temporary storage warehouse. To avoid mismatches between the ingot length information and the cut ingots, the cutting machine typically does not directly transmit the ingot length information to the warehouse's system. Instead, the ingot length information is manually copied and transported with the carts for entry. This method, which requires dedicated weighing and relies entirely on manual recording, is not only inefficient but also prone to errors due to misrecording, omissions, or incorrect entries. This can lead to errors or difficulties in processes that depend on the recorded data, impacting silicon single crystal production. Summary of the Invention

[0004] In view of this, and to address the above shortcomings, it is necessary to propose a crystal rod transfer trolley, a crystal rod processing and storage system, and a crystal rod transportation method, so as to realize the weighing of crystal rods through the crystal rod transfer trolley and the uploading of crystal rod data to the crystal rod temporary storage library.

[0010] Preferably, a sliding rod is provided on the support frame below the crystal rod along the axial direction of the crystal rod, and a plurality of isolation components are slidably disposed on the sliding rod; wherein, the lower end of each isolation component is slidably disposed on the sliding rod, and the upper end is a retractable structure covered with a silicone layer, which is used to extend the upper end of the isolation component and place it between two adjacent crystal rods when the crystal rod transfer trolley transfers multiple segments of the crystal rod after they have been cut, so as to prevent the two adjacent crystal rods from colliding.

[0011] Preferably, a level is provided on the load-bearing frame, and a leveling component is provided below the weighing mechanism for leveling the weighing mechanism according to the level.

[0012] Preferably, the motion mechanism is a swivel wheel.

[0013] In a second aspect, the present invention provides a crystal rod processing and storage system, comprising: a crystal rod transfer trolley, a grinding machine, a cutting machine and a crystal rod temporary storage warehouse as described in the first aspect; The control mechanism of the crystal rod transfer trolley is connected to the systems of the grinding machine, the cutting machine and the crystal rod temporary storage warehouse. The crystal rod transfer trolley is used to transfer crystal rods and weigh them.

Detailed Implementation

[0024] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0025] See Figure 1-5 This invention provides a crystal rod transfer trolley 100, characterized in that it includes: a fixed frame 10, a load-bearing frame 20, a motion mechanism 30, a weighing mechanism 40, and a control mechanism 50; the motion mechanism 30 is disposed below the fixed frame 10 and is used to drive the fixed frame 10 to move; the weighing mechanism 40 is fixedly installed on the fixed frame 10; the upper end of the load-bearing frame 20 is used to place the crystal rod 001, and the lower end extends from above the fixed frame 10 into the inner side of the fixed frame 10 and bears the load. The lower end of the frame 20 is connected to the upper surface of the weighing mechanism 40 so as to weigh the crystal rod 001 by the weighing mechanism 40; the control mechanism 50 is disposed on the fixed frame 10 and electrically connected to the weighing mechanism 40, and is used to receive the crystal rod weighing data sent by the weighing mechanism 40; the control mechanism 50 is also communicatively connected to the crystal rod temporary storage 400 system, and is used to upload the weighing data of the stored crystal rod to the crystal rod temporary storage 400 system when the crystal rod is stored in the crystal rod temporary storage 400.

[0026] In this embodiment, the ingot transfer cart 100 can weigh the ingots during the transfer process, eliminating the need for a dedicated weighing device. Furthermore, this solution establishes a communication connection between the ingot transfer cart 100 and the tumbling mill 200, the cutting machine 300, and the ingot temporary storage system 400. This allows the cart to store weighing data, tumbling data, and cutting data, which are then uploaded to the ingot temporary storage system 400 during ingot storage. This enables autonomous data recording and transmission, improving efficiency and avoiding errors caused by manual recording.

[0027] After the crystal ingot is drawn and removed from the furnace, its temperature is typically around 90 degrees Celsius. At this point, the ingot needs to be placed on a transfer trolley for natural cooling to room temperature. To accelerate the cooling efficiency of the crystal ingot, thereby improving the processing efficiency and shortening the processing time, in one embodiment, a cooling mechanism 60 is considered to be installed on the support frame 20 to accelerate the cooling of the crystal ingot placed on the transfer trolley after the crystal ingot is drawn and before it is tumbled. The control mechanism 50 is electrically connected to the cooling mechanism 60 and is used to control the start / stop and power of the cooling mechanism 60.

[0028] Specifically, the cooling mechanism 60 may include several cooling fans, which are fixedly mounted on the support frame 20 and located below the crystal rod, with the airflow direction directly facing the crystal rod above. Thus, the control mechanism 50 controls the start and stop of the cooling fans to achieve rapid cooling of the crystal rod. Of course, the control mechanism 50 can also control the output power of the cooling fans, thereby adjusting the airflow rate to ensure high cooling efficiency while avoiding damage to the crystal rod.

[0029] To achieve greater uniformity in the cooling of the crystal ingot and ensure consistent cooling efficiency across all surfaces, in one embodiment, a crystal ingot rotation mechanism 70 is also considered for rotating the crystal ingot on the support frame 20. The control mechanism 50 is electrically connected to the crystal ingot rotation mechanism 70 and is used to control the start, stop, and rotation speed of the crystal ingot rotation mechanism 70. Thus, by controlling the operation of the crystal ingot rotation mechanism 70 through the control mechanism 50, the crystal ingot placed on the crystal ingot can rotate, resulting in more uniform cooling of the crystal ingot by the cooling mechanism 60 below, and higher cooling consistency across all surfaces.

[0030] Specifically, the crystal rod rotation mechanism 70 may include two identical roller shaft groups 71, a first gear 72, a second gear 73, a chain 74, and a drive motor 75. The two roller shaft groups 71 are arranged parallel to each other on the upper end of the support frame 20 and located on both sides of the crystal rod, so that the crystal rod is placed on the two roller shaft groups 71. Each roller shaft group 71 consists of at least one roller shaft, and both ends of each roller shaft are rotatably mounted on the support frame 20 through bearings. When there is more than one roller shaft in the roller shaft group 71, the closer ends of two adjacent roller shafts share a bearing. The outermost roller shaft of one of the roller shaft groups 71 is connected to the first gear 72. The first gear 72 is connected to the second gear 73 through the chain 74. The second gear 73 is connected to the drive end of the drive motor 75 so that the drive motor 75 drives the second gear 73 to rotate, thereby driving the roller shaft group 71 to rotate, and thus realizing the rotation of the crystal rod.

[0031] In this embodiment, each roller group 71 can be composed of a single roller. Of course, in order to improve the strength of the roller and avoid the situation where a roller is deformed or even broken due to being suspended in the middle without support, each roller group 71 can be composed of multiple short rollers connected together.

[0032] Furthermore, considering that the crystal ingots will be cut into multiple short crystal ingots after passing through the cutting machine 300, in order to ensure that crystal ingots of the same batch are stored together, multiple short crystal ingots will be placed simultaneously on the crystal ingot transfer trolley 100 and transported to the crystal ingot temporary storage warehouse 400 for storage. However, when multiple short crystal ingots are transported simultaneously on the crystal ingot transfer trolley 100, the crystal ingots may collide due to the trolley's starting, unstable operation, and sudden braking, resulting in damage to the crystal ingots. Accordingly, a sliding rod 81 is installed on the support frame 20 below the crystal ingots, along the axial direction of the crystal ingots. Several isolation components 82 are slidably mounted on the sliding rod 81. The lower end of each isolation component 82 is slidably mounted on the sliding rod 81, and the upper end is a retractable structure covered with a silicone layer. When the crystal ingot transfer trolley 100 transports the cut crystal ingot segments, the upper end of the isolation component 82 extends out and is placed between two adjacent crystal ingots to prevent collisions between adjacent crystal ingots.

[0033] In this embodiment, each isolation component 82 includes multiple components and is adjustable by sliding. Thus, according to the number of short crystal rods cut by the cutting machine 300, the corresponding number of isolation components 82 can be selected and slid to the corresponding position so that the isolation component 82 is located between two adjacent crystal rods, so as to avoid collisions between crystal rods during the transfer process.

[0034] In addition, in one embodiment, a level 90 may be provided on the load-bearing frame 20, and a leveling component is provided below the weighing mechanism 40 for leveling the weighing mechanism 40 according to the level 90, so as to ensure the accuracy of weighing the crystal rod.

[0035] The motion mechanism 30 can be a caster wheel, which has a locking function so that it can be locked when the crystal rod transfer trolley 100 is not needed to run.

[0036] The control mechanism 50 may include a human-machine interface module, such as a human-machine interface display screen. Operators can use the human-machine interface module to control the start and stop of the cooling mechanism 60 and the crystal rod rotation mechanism 70, as well as to adjust parameters. Furthermore, through the human-machine interface module, operators can establish communication connections with the tumbling machine 200 and the cutting machine 300, thereby enabling data transmission. For example, when the crystal rod transfer trolley 100 transports the crystal rod to the No. 3 tumbling machine 200, operators can use the human-machine interface module to establish a communication connection between the control mechanism 50 and the No. 3 tumbling machine 200, allowing the No. 3 tumbling machine 200 to send tumbling data to the control mechanism 50 for storage. After tumbling is completed, the control mechanism 50 automatically disconnects from the No. 3 tumbling machine 200, or operators can disconnect from the No. 3 tumbling machine 200 via the human-machine interface module. Similarly, establishing a communication connection between the crystal rod transfer trolley 100 and the cutting machine 300 is similar to establishing a communication connection with the tumbling machine 200.

[0037] like Figure 6 As shown, the present invention also provides a crystal rod processing and storage system, including: a crystal rod transfer trolley 100, a grinding machine 200, a cutting machine 300, and a crystal rod temporary storage 400 as described in the above embodiments; The control mechanism 50 of the crystal rod transfer trolley 100 is connected to the system communication of the grinding machine 200, the cutting machine 300 and the crystal rod temporary storage 400 respectively. The crystal rod transfer trolley 100 is used to transfer crystal rods and weigh them. The tumbling mill 200 is used to tumble the crystal rods transported by the crystal rod transfer trolley 100 and send the tumbling data to the control mechanism 50 of the crystal rod transfer trolley 100 for storage. The cutting machine 300 is used to cut the crystal rods transported by the crystal rod transfer cart 100 and send the cutting data to the control mechanism 50 of the crystal rod transfer cart 100 for storage. The crystal rod transfer trolley 100 is used to upload the weighing data, tumbling data and cutting data of the stored crystal rods to the system of the crystal rod temporary storage 400 when storing the cut crystal rods in the crystal rod temporary storage 400, so that the system of the crystal rod temporary storage 400 can record the storage.

[0038] like Figure 6 As shown, the present invention also provides a method for transporting crystal rods, which is based on the crystal rod processing and storage system described above, and the method may include the following steps: S1: The pulled crystal rod is placed on the crystal rod transfer trolley 100; S2: The cooling mechanism 60 is activated by the control mechanism 50 to cool the crystal rod; S3: The crystal rod transfer trolley 100 weighs the crystal rod, obtains the first weighing data, and stores the first weighing data in the control mechanism 50; S4: After the crystal rod is cooled to room temperature, the crystal rod transfer trolley 100 transports the crystal rod to the grinding machine 200, uses the grinding machine 200 to grind the crystal rod, and sends the grinding data to the crystal rod transfer trolley 100. S5: After the tumbling process is completed, when the crystal rod is transferred from the tumbling machine 200 to the crystal rod transfer trolley 100, the crystal rod transfer trolley 100 weighs the crystal rod, obtains the second weighing data, and stores the second weighing data in the control mechanism 50. S6: After tumbling, the crystal rod transfer trolley 100 transports the crystal rod to the cutting machine 300, which cuts the crystal rod and sends the cutting data to the crystal rod transfer trolley 100. S7: When placing the cut crystal rods on the crystal rod transfer trolley 100, record the weighing data of each crystal rod before and after placement in sequence, and send it to the control mechanism 50 so that the control mechanism 50 can determine the weight of each cut crystal rod and obtain the third weighing data. S8: The crystal rod transfer trolley 100 transports the cut crystal rods to the crystal rod temporary storage warehouse 400 for storage, and uploads various weighing data, rolling data and cutting data to the system of the crystal rod temporary storage warehouse 400 so that the system of the crystal rod temporary storage warehouse 400 can record the entry and bind it to the corresponding crystal rod.

[0039] In this embodiment, the grinding data may include the diameter data, surface flatness, diameter tolerance, and abrasive grinding process parameters of the crystal rod, while the cutting data of the cutting machine 300 may include the length data and cutting accuracy of each crystal rod segment. By combining the first weighing data with the feeding data of the single crystal furnace, not only can the feeding of the next furnace be guided, but also the first weighing data combined with the second and third weighing data can determine the loss of the crystal rod during processing.

[0040] In addition, after the drawn crystal rod is placed on the crystal rod transfer trolley 100, the temperature of the crystal rod can be monitored in real time by a temperature sensor, and the cooling mechanism 60 can be turned on or off according to the monitored temperature, and the power of the cooling mechanism 60 can be adjusted.

[0041] The method embodiments and apparatus and system embodiments in this specification are based on the same inventive concept. For detailed descriptions, please refer to the descriptions of the apparatus and systems, which will not be repeated here.

Those skilled in the art will understand that implementing all or part of the processes of the above embodiments and making equivalent changes according to the claims of this invention still fall within the scope of the invention.
