Description

Technical Field

[0001] This invention relates to the field of single crystal cutting technology, and specifically to a cutting method and system based on a multi-head cutting machine. Background Technology

[0002] When using a multi-head cutting machine to cut N-type crystal rods, the multi-head cutting machine is generally a 7-head or 9-head cutting machine. The multi-head cutting machine only has double-wire mesh cutters at the head and tail, so that the head and tail pieces of the crystal rod can be taken at the same time after cutting for oxygen and carbon detection.

[0003] However, most crystal rods cannot be cut from both the beginning and end of the wafer at the same time. Therefore, the equipment needs to be cut off and then a second wafer is taken, which adds an extra step of processing, a single-head cutting process, and a long waiting time, resulting in various production backlogs and making normal production impossible. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting method and system based on a multi-blade cutter. By shielding the cutter heads, the multi-blade cutter can meet the needs of most crystal rods, not only removing the length of the head and tail sections at the same time, but also improving production efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A cutting method based on a multi-blade cutter, the method specifically includes the following steps:

[0007] S1. Place a crystal rod with k segments to be cut under an N-head cutting machine. Based on the shape and size of the crystal rod and the number to be cut, obtain the initial cutting parameters corresponding to the cutting head and the initial cutting distance between two adjacent cutting heads. The N-head cutting machine includes N cutting heads arranged in a horizontal direction, and k = 1, 2, ..., n, N = 1, 2, ..., n.

[0008] And determine whether N is greater than k and whether k is equal to N-1. If yes, start the N-head cutting machine to perform synchronous cutting work according to the initial cutting parameters of the cutter head and the initial cutting distance between two adjacent cutters. If no, go to step S2.

[0009] S2. Eliminate the first-ranked head cutter and the last-ranked tail cutter from the N cutter heads. Then, randomly select N-1-k cutter heads from the remaining cutter heads as shield cutter heads.

[0010] The area to be processed is divided on N sequentially arranged cutter heads according to the position of the shielding cutter heads. The area to be processed consists of cutter heads arranged horizontally on the left side of the shielding area, a shielding area composed of i shielding cutter heads, and cutter heads located on the right side of the shielding area, where i <N-1-k;

[0011] S3. Adjust the parameters according to the initial cutting parameters to obtain the shielding parameters corresponding to the shielding head;

[0012] Based on the number i of shielded cutters in the area to be processed, the initial cutting distance between two adjacent cutters in the area to be processed is segmented to obtain the segmented cutting distance between two adjacent cutters in the area to be processed, so that the N-cutter cutter can perform synchronous cutting work according to the processed parameters.

[0013] Furthermore, the cutting parameters refer to the cutting head's ability to contact and cut the crystal rod when performing cutting work according to the corresponding cutting parameters.

[0014] Furthermore, in S3, the parameter adjustment process specifically involves:

[0015] After adjusting the initial cutting parameters, shielding parameters corresponding to the shielded cutter head are obtained. These shielding parameters are used when the N-cutter head cutting machine performs synchronous cutting work according to the processed parameters, and there is a gap between the corresponding shielded cutter head and the upper surface of the crystal rod.

[0016] Furthermore, in S3, the distance segmentation process specifically involves:

[0017] Based on the number i of shielded cutting heads in the area to be processed, the initial cutting distance between two adjacent cutting heads in the area to be processed is segmented to obtain the segmented cutting distance between two adjacent cutting heads in the area to be processed. The segmented cutting distance is used when the N-head cutting machine performs synchronous cutting work according to the processed parameters, so that the length of the crystal rod generated by the cutting head on the left side of the shielded area and the cutting head on the right side of the shielded area in the area to be processed according to the segmented cutting distance is the same as the length of the crystal rod generated by the two adjacent cutting heads according to the cutting distance.

[0018] Furthermore, S3 specifically includes the following steps:

[0019] S31. Obtain the cutting speed and descent distance of the cutting head in the initial cutting parameters. Reduce the cutting speed and descent distance of the cutting head in the initial cutting parameters. Generate shielding parameters corresponding to the shielded cutting head based on the reduced cutting speed and descent distance of the cutting head.

[0020] S32. Based on the number i of shielded cutter heads in the area to be processed, divide the initial cutting distance between two adjacent cutter heads in the area to be processed into i+1 segments to obtain the segmented cutting distance between two adjacent cutter heads in the area to be processed, i.e., segmented cutting distance = initial cutting distance / (i+1).

[0021] S33. Start the N-head cutting machine for synchronous cutting based on the processed parameters.

[0022] Furthermore, the head and tail blades are double-wire mesh, and the remaining blades after elimination are single-wire mesh.

[0023] Furthermore, the N-head cutting machine includes a 7-head cutting machine and a 9-head cutting machine.

[0024] A cutting system based on a multi-blade cutter includes:

[0025] N-head cutting machine: includes N cutting heads arranged sequentially in the horizontal direction, where N = 1, 2, ..., n, used for cutting crystal rods;

[0026] Initial cutting parameter acquisition module: Based on the shape and size of the crystal rod and the number to be cut, the module obtains the initial cutting parameters corresponding to the cutting head, as well as the initial cutting distance between two adjacent cutting heads;

[0027] The N-head cutting machine operation status judgment module determines whether N is greater than k and whether k is equal to N-1. If yes, the N-head cutting machine is started to perform synchronous cutting work according to the initial cutting parameters of the cutting head and the initial cutting distance between two adjacent cutting heads. If no, synchronous cutting work is performed according to the processed parameters.

[0028] Module for obtaining shielded cutting heads: Exclude the first-ranked head cutting head and the last-ranked tail cutting head from the N cutting heads, and then randomly select N-1-k cutting heads from the remaining cutting heads as shielded cutting heads;

[0029] The module for obtaining the area to be processed divides the area to be processed onto N sequentially arranged cutting heads according to the position of the shielding cutting heads. The area to be processed consists of cutting heads arranged horizontally in sequence on the left side of the shielding area, a shielding area composed of i shielding cutting heads, and cutting heads located on the right side of the shielding area. Where i... <N-1-k;

[0030] Parameter processing module: Based on the initial cutting parameters, the parameter is adjusted to obtain the shielding parameters corresponding to the shielding head; and based on the number i of shielding heads in the area to be processed, the initial cutting distance between two adjacent heads in the area to be processed is segmented to obtain the segmented cutting distance between two adjacent heads in the area to be processed.

[0031] The beneficial effects of this invention are:

[0032] This invention provides a cutting method based on a multi-blade cutter. By shielding the cutter heads, the multi-blade cutter can meet the needs of most crystal rods. It can not only remove the length of the head and tail of the wafers at the same time, but also improve production efficiency. Attached Figure Description

[0042] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0044] Example 1

[0045] When using a multi-head cutting machine to cut N-type crystal rods, these machines are typically 7-head or 9-head cutting machines. However, the multi-head cutting machine only has double-wire mesh cutting heads at the head and tail, allowing the crystal rods located at the head and tail to be simultaneously sampled for oxygen and carbon detection after cutting.

[0046] However, most crystal rods cannot be cut from both the beginning and end of the wafer at the same time. Therefore, the equipment needs to be cut off and then a second wafer is taken, which adds an extra step of processing, a single-head cutting process, and a long waiting time, resulting in various production backlogs and making normal production impossible.

[0047] Therefore, the present invention provides a cutting method based on a multi-blade cutter, the method specifically including the following steps:

[0048] S1. Place a crystal rod with k segments to be cut under an N-head cutting machine. Based on the shape and size of the crystal rod and the number to be cut, obtain the initial cutting parameters corresponding to the cutting head and the initial cutting distance between two adjacent cutting heads. The N-head cutting machine includes N cutting heads arranged in a horizontal direction, and k = 1, 2, ..., n, N = 1, 2, ..., n.

[0049] And determine whether N is greater than k and whether k is equal to N-1. If yes, start the N-head cutting machine to perform synchronous cutting work according to the initial cutting parameters of the cutter head and the initial cutting distance between two adjacent cutters. If no, go to step S2.

[0050] S2. Eliminate the first-ranked head cutter and the last-ranked tail cutter from the N cutter heads. Then, randomly select N-1-k cutter heads from the remaining cutter heads as shield cutter heads.

[0051] The area to be processed is divided on N sequentially arranged cutter heads according to the position of the shielding cutter heads. The area to be processed consists of cutter heads arranged horizontally on the left side of the shielding area, a shielding area composed of i shielding cutter heads, and cutter heads located on the right side of the shielding area, where i <N-1-k;

[0052] S3. Adjust the parameters according to the initial cutting parameters to obtain the shielding parameters corresponding to the shielding head;

[0053] Based on the number i of shielded cutters in the area to be processed, the initial cutting distance between two adjacent cutters in the area to be processed is segmented to obtain the segmented cutting distance between two adjacent cutters in the area to be processed, so that the N-cutter cutter can perform synchronous cutting work according to the processed parameters.

[0054] Preferably, the cutting parameters refer to the cutting head being able to contact the crystal rod and cut the crystal rod when performing the cutting work according to the corresponding cutting parameters.

[0055] Preferably, in S3, the parameter adjustment process specifically involves:

[0056] After adjusting the initial cutting parameters, shielding parameters corresponding to the shielded cutter head are obtained. These shielding parameters are used when the N-cutter head cutting machine performs synchronous cutting work according to the processed parameters, and there is a gap between the corresponding shielded cutter head and the upper surface of the crystal rod.

[0057] Preferably, in S3, the distance segmentation process specifically includes:

[0058] Based on the number i of shielded cutting heads in the area to be processed, the initial cutting distance between two adjacent cutting heads in the area to be processed is segmented to obtain the segmented cutting distance between two adjacent cutting heads in the area to be processed. The segmented cutting distance is used when the N-head cutting machine performs synchronous cutting work according to the processed parameters, so that the length of the crystal rod generated by the cutting head on the left side of the shielded area and the cutting head on the right side of the shielded area in the area to be processed according to the segmented cutting distance is the same as the length of the crystal rod generated by the two adjacent cutting heads according to the cutting distance.

[0059] Preferably, step S3 specifically includes the following steps:

[0060] S31. Obtain the cutting speed and descent distance of the cutting head in the initial cutting parameters. Reduce the cutting speed and descent distance of the cutting head in the initial cutting parameters. Generate shielding parameters corresponding to the shielded cutting head based on the reduced cutting speed and descent distance of the cutting head.

[0061] S32. Based on the number i of shielded cutter heads in the area to be processed, divide the initial cutting distance between two adjacent cutter heads in the area to be processed into i+1 segments to obtain the segmented cutting distance between two adjacent cutter heads in the area to be processed, i.e., segmented cutting distance = initial cutting distance / (i+1).

[0062] S33. Start the N-head cutting machine for synchronous cutting based on the processed parameters.

[0063] Preferably, the head and tail blades are double-wire mesh, and the remaining blades after elimination are single-wire mesh.

[0064] Preferably, the N-head cutting machine includes a 7-head cutting machine and a 9-head cutting machine.

[0065] Based on the above principles, the present invention will be further described as follows:

[0066] Because most multi-blade cutting machines on the market are 7-blade or 9-blade cutting machines, only the head and tail blades have double-wire mesh, while the rest are single-wire mesh. This means that only when the head and tail blades cut the crystal rod can the requirement to remove the head and tail wafers for oxygen and carbon testing be met. Therefore, in actual production, most crystal rods cannot have their head and tail wafers removed simultaneously. For example, a 7-blade cutting machine can only meet this requirement when cutting the crystal rod into 6 segments; a 9-blade cutting machine can only meet this requirement when cutting the crystal rod into 8 segments.

[0067] To address the aforementioned issues, current technologies employ a secondary strip removal process after the strip is removed from the machine. This results in the following actual processing flow for the cutting machine: loading a round bar - cutting with a blade - removing a 2mm head strip - transferring it to a transport vehicle - waiting for the tail strip to be cut - removing the tail strip with a single blade - measuring oxygen and carbon - stamping and transferring. This single-step processing flow is extremely complex, resulting in excessive waiting time during the entire production process, leading to slow production efficiency and an inability to meet production demands.

[0068] Therefore, in order to avoid adding steps, this invention eliminates the secondary wafer removal process after the original processing flow. Instead, it uses a multi-head cutting machine with a shielded cutter head to process the crystal rod. The improved processing flow is: top round rod - cut with a blade - remove 2mm head and tail wafers - transfer to a transport vehicle - measure oxygen and carbon - stamp and transfer. This greatly saves process time. Compared with the efficiency of the existing processing flow, the efficiency of the processing flow in this invention is improved by more than 50%.

[0069] Because the distance between the cutters of different models of multi-head cutting machines is limited and there is a minimum cutting distance between the cutters, it is necessary to select the cutter based on the minimum cutting distance between the cutters when cutting different quantities of crystal rods. Otherwise, the cutting distance between the cutters cannot be adjusted, and the crystal rods generated between the cutters on the left and right sides of the shielded cutter will not reach the required length.

[0070] Specifically, such as Figure 2As shown, in this embodiment, a 7-blade cutter is selected to cut a crystal rod with 5 segments. Based on the crystal rod, initial cutting parameters corresponding to the cutter heads and the initial cutting distance between two adjacent cutter heads can be obtained. The initial cutting parameters include a cutter head cutting speed of 4 mm / min, a cutter head descent distance of 100 mm, and an initial cutting distance between two adjacent cutter heads of 500 mm. The cutter head cutting speed refers to the feed rate of the cutter head, which is generally set between 0.1-5 mm / min. The cutter head descent distance is generally set between 80-120 mm, and the cutting distance between two adjacent cutter heads is generally greater than 240 mm and less than 900 mm.

[0071] The operating status of the 7-cutter cutter is determined by comparing the number of cutters in the 7-cutter cutter with the number of crystal rods to be cut. The 7-cutter cutter has two operating states: The first is normal operation, where the 7-cutter cutter cuts 6 segments of crystal rod, and an N-cutter cutter is started synchronously based on the initial cutting parameters and the initial cutting distance between two adjacent cutters. The second is shielded cutting state, where the 7-cutter cutter cuts fewer than 6 segments of crystal rod, requiring parameter processing of the initial cutting parameters and the initial cutting distance between two adjacent cutters before starting the N-cutter cutter synchronously.

[0072] In this embodiment, a 7-blade cutting machine is used to cut a crystal rod with 5 segments to be cut, which is the second shielded blade operating state. Then, a blade is randomly selected between the head blade and the tail blade as the shielded blade. For the shielded blade, the initial cutting parameters and the initial cutting distance between two adjacent blades are first processed. Specifically, according to the initial cutting parameters, the blade cutting speed and the blade descent distance are reduced, so that the blade cutting speed of the shielded blade is 3mm / min and the blade descent distance is 80mm.

[0073] Based on the reduced cutting speed and decreased descent distance of the cutter head, shielding parameters corresponding to the shielded cutter head are generated. When the N-cutter head cutting machine performs synchronous cutting according to these processed parameters, a gap exists between the shielded cutter head and the upper surface of the crystal ingot. In other words, the shielded cutter head will not cut the crystal ingot. Figure 3 As shown.

[0074] Then, since the shielding cutter does not cut the crystal rod, no segmented crystal rod will be generated between the shielding cutter and the two adjacent cutters. Instead, segmented crystal rod will be generated between the two cutters located on the left and right sides of the shielding cutter. The initial cutting distance refers to the distance between two adjacent cutters. Therefore, when the parameters are not adjusted, the length of the segmented crystal rod generated between the two cutters located on the left and right sides of the shielding cutter will be 1000mm according to the initial cutting distance.

[0075] Therefore, the initial cutting distance between the shielding cutter head and its two adjacent cutter heads is segmented. Since there is only one shielding cutter head, and only one shielding cutter head exists between any two adjacent cutter heads, the initial cutting distance between the shielding cutter head and its two adjacent cutter heads is divided into two segments. This results in a segmented cutting distance of 250mm between the shielding cutter head and the corresponding left and right side cutter heads, making the cutting distance between the two cutter heads located on the left and right sides of the shielding cutter head 500mm. Figure 4 As shown, if the length of the crystal rod generated by the two cutters located on the left and right sides of the shielding cutter head according to the segmented cutting distance is the same as the length of the crystal rod generated by the two adjacent cutters according to the cutting distance, the cutting of the crystal rod can be completed.

[0077] A cutting system based on a multi-blade cutter includes:

[0078] N-head cutting machine: includes N cutting heads arranged sequentially in the horizontal direction, where N = 1, 2, ..., n, used for cutting crystal rods;

[0079] Initial cutting parameter acquisition module: Based on the shape and size of the crystal rod and the number to be cut, the module obtains the initial cutting parameters corresponding to the cutting head, as well as the initial cutting distance between two adjacent cutting heads;

[0080] The N-head cutting machine operation status judgment module determines whether N is greater than k and whether k is equal to N-1. If yes, the N-head cutting machine is started to perform synchronous cutting work according to the initial cutting parameters of the cutting head and the initial cutting distance between two adjacent cutting heads. If no, synchronous cutting work is performed according to the processed parameters.

[0081] Module for obtaining shielded cutting heads: Exclude the first-ranked head cutting head and the last-ranked tail cutting head from the N cutting heads, and then randomly select N-1-k cutting heads from the remaining cutting heads as shielded cutting heads;

[0082] Parameter processing module: Based on the initial cutting parameters, the module performs parameter adjustment to obtain the shielding parameters corresponding to the shielding head. Based on the initial cutting distance between two adjacent heads, the module performs distance segmentation processing on the cutting distance between the two heads located on the left and right sides of the shielding head to obtain the segmented cutting distance between the shielding head and the adjacent heads.
