Description

Technical Field

[0001] This invention relates to the field of workpiece positioning, and more particularly to a correction and positioning component and method. Background Technology

[0002] A photovoltaic module is a product that converts light energy into electrical energy. Its main component is a silicon solar cell, which is made by cutting high-purity monocrystalline silicon rods.

[0003] Currently, the cutting of monocrystalline silicon rods has become an assembly line operation, but the production process often results in deviations and inaccurate positioning, which prevents subsequent processes from proceeding normally. Therefore, it is necessary to correct and position the monocrystalline silicon rods before production. In the existing correction process, the monocrystalline silicon rods are finally positioned through a single correction. However, since monocrystalline silicon rods are brittle materials, they are prone to collisions or wear due to excessive impact force during a single correction and positioning process, resulting in a large amount of waste. At the same time, a single correction process can easily lead to insufficient correction accuracy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a correction and positioning component and method for correcting and positioning a monocrystalline silicon rod without damaging it.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A correction and positioning component is used for the correction and positioning of a monocrystalline silicon rod, comprising an installation platform, a support rail, and a correction component, wherein the support rail and the correction component are both disposed on the installation platform;

[0007] The correction assembly includes a first correction assembly and a second correction assembly; the first correction assembly includes a first correction cylinder and a first positioning plate positioned opposite each other, the first correction cylinder and the first positioning plate being respectively disposed on both sides of the support rail;

[0008] The second correction component is located behind the first correction component. The second correction component includes a second correction cylinder and a second positioning plate that are positioned opposite each other. The second correction cylinder and the second positioning plate are respectively located on both sides of the support rail.

[0009] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is as follows:

[0010] A correction and positioning method, applied to a correction and positioning component, includes the following steps:

[0011] S1. Use the first correction cylinder to press the single crystal silicon rod against the buffer plate;

The monocrystalline silicon rod is initially positioned by a first correction cylinder and a first positioning plate, and then the monocrystalline silicon rod is positioned secondary by a second correction cylinder and a second positioning plate.

[0034] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0035] Please refer to Figures 1 to 9 A correction and positioning component is used for the correction and positioning of a monocrystalline silicon rod, including an installation platform 1, a support rail 2 and a correction component 3, wherein the support rail 2 and the correction component 3 are both disposed on the installation platform 1;

[0036] The correction component 3 includes a first correction component 31 and a second correction component 32; the first correction component 31 includes a first correction cylinder 311 and a first positioning plate 312 positioned opposite each other, and the first correction cylinder 311 and the first positioning plate 312 are respectively disposed on both sides of the support rail 2.

[0037] The second correction component 32 is located behind the first correction component 31. The second correction component 32 includes a second correction cylinder 321 and a second positioning plate 322 that are positioned opposite each other. The second correction cylinder 321 and the second positioning plate 322 are respectively located on both sides of the support rail 2.

[0038] As can be seen from the above description, the beneficial effects of the present invention are as follows: a correction and positioning component and method are provided, which divides the correction process into primary correction and secondary correction. The monocrystalline silicon rod is initially positioned by a first correction cylinder and a first positioning plate, and then the monocrystalline silicon rod is positioned secondary by a second correction cylinder and a second positioning plate. This reduces the stress on the monocrystalline silicon rod during the positioning process, prevents damage, and improves the positioning accuracy.

[0039] Furthermore, the support rail 2 includes a ball bearing support rail 21 and a flexible support rail 22 that are connected along the axial direction of the support rail. The ball bearing support rail 21 is located between the first straightening cylinder 311 and the first positioning plate 312, and the flexible support rail 22 is located between the second straightening cylinder 321 and the second positioning plate 322.

[0040] As described above, the friction generated by the monocrystalline silicon rod during the straightening process is reduced by setting the ball bearing support rail. At the same time, the first straightening component is used to perform preliminary straightening of the monocrystalline silicon rod. After the preliminary positioning is completed, the dynamic friction between the monocrystalline silicon rod and the rail is changed to static friction by using the flexible support rail. At the same time, the position of the monocrystalline silicon rod is finely adjusted and clamped by the second straightening component, thereby completing the final positioning, reducing the material loss of the monocrystalline silicon rod during the straightening process and achieving the straightening and positioning effect.

[0041] Furthermore, the installation platform 1 is provided with an installation groove 11, and the first positioning plate 312 and the second positioning plate 322 are detachably connected to the installation platform 1 through the installation groove 11;

[0042] The axis of the mounting groove 11 is parallel to the axis of the support rail 2; there are multiple mounting grooves 11, which are arranged sequentially at a first preset interval along a direction perpendicular to the axis of the support rail 2.

[0043] As described above, in order to accommodate monocrystalline silicon rods of different sizes, the positioning plate is detachably connected to the mounting platform 1 via the mounting groove 11. At the same time, the axis of the mounting groove 11 is parallel to the axis of the support rail 2 and multiple mounting grooves 11 are arranged sequentially at a first preset interval along a direction perpendicular to the axis of the support rail 2 (that is, multiple mounting grooves 11 for positioning plates are provided in the width direction of the monocrystalline silicon rod). Thus, the positioning plate can be placed in different mounting grooves 11 according to the actual width of the monocrystalline silicon rod, thereby ensuring that the center of gravity of the monocrystalline silicon rod is always located on the support rail 2 and preventing the monocrystalline silicon rod from falling off the support rail 2 during the correction and positioning process.

[0044] Furthermore, the projection perpendicular to the axis of the support rail is a first projection plane. On the first projection plane, the horizontal distance between the installation position of the first positioning plate and the center of the support rail is less than the horizontal distance between the installation position of the second positioning plate and the center of the support rail.

[0045] As described above, in order to prevent wear between the monocrystalline silicon rod and the positioning plate, the horizontal distance between the installation position of the first positioning plate and the center of the support rail is less than the horizontal distance between the installation position of the second positioning plate and the center of the support rail. The principle is as follows: after the monocrystalline silicon rod is initially positioned by the first straightening cylinder 311 and the first positioning plate 312, the side of the monocrystalline silicon rod is in contact with the first positioning plate 312. In order to prevent the side of the monocrystalline silicon rod from colliding with or generating large friction with the second positioning plate 322 during transportation, which would cause damage to the monocrystalline silicon rod, the minimum distance between the second positioning plate 322 and the support rail 2 is controlled to be greater than the minimum distance between the first positioning plate 312 and the support rail 2.

[0046] Furthermore, both the first positioning plate 312 and the second positioning plate 322 are provided with buffer plates 33, and the installation positions of the buffer plates 33 are respectively opposite to the first correcting cylinder 311 and the second correcting cylinder 321.

[0047] As described above, in order to prevent the monocrystalline silicon rod from colliding with the positioning plate under the action of the straightening cylinder, thus causing damage to the monocrystalline silicon rod, a buffer plate 33 is set on the positioning plate at the position corresponding to the straightening cylinder to absorb the inertial force. At the same time, it is not necessary to distribute the buffer plate 33 evenly throughout the entire positioning plate, thus saving materials and reducing costs.

[0048] Furthermore, the number of support rails 2 is greater than or equal to 2; it also includes a slide 4, which is disposed between the support rails 2, and the slide 4 is provided with a telescopic part, which is used to control the movement of the slide 4 in the vertical direction.

[0049] As described above, in order to accommodate monocrystalline silicon rods of different sizes and provide stable support for them, the number of support rails 2 is greater than or equal to 2. This ensures that the center of gravity of the monocrystalline silicon rod falls on or between the support rails 2, preventing the monocrystalline silicon rod from slipping or tipping over. To facilitate the transportation of the monocrystalline silicon rod, a slide 4 is installed between the support rails 2. The slide 4 can both run along the axis of the support rail 2 and lift the monocrystalline silicon rod through the telescopic part, thereby allowing the monocrystalline silicon rod to detach from the support rail 2 during transportation and reducing friction.

[0050] Furthermore, it also includes a loading sensor 5 and a distance sensing sensor 6 disposed on the mounting platform 1; the loading sensor 5 is located on one side of the support rail 2 and is positioned opposite to the first corrective cylinder 311; the distance sensing sensor 6 is located on both sides of the support rail 2 between the first corrective cylinder 311 and the second corrective cylinder 321.

[0051] The distance sensing sensor 6 has two distance sensing units 61 arranged at a fixed interval in the vertical direction.

[0052] As described above, in order to improve the accuracy of the correction and positioning process, a feeding sensor 5 and a distance sensing sensor 6 are set up. The feeding sensor 5 is positioned opposite the first correction cylinder 311. The first correction cylinder 311 is only started when the feeding sensor 5 detects the presence of complete material. At the same time, in order to accurately position, a distance sensing sensor 6 is set up to accurately sense the travel distance of the monocrystalline silicon rod and control the second correction cylinder 321 to clamp the monocrystalline silicon rod at a preset position. Preferably, the distance sensing sensor 6 has two distance sensing parts 61 at a fixed interval in the vertical direction. The principle is that in order to prevent defects or tilting on the side of the detected monocrystalline silicon rod, which would cause a large error in the distance sensing, the two distance sensing parts 61 in the vertical direction are used to simultaneously project and sense the side of the monocrystalline silicon rod. After obtaining the projected distance (the distance between the distance sensing part 61 and the side of the monocrystalline silicon rod), if the two are different, the average of the two projected distances is taken as the final projected distance. At the same time, the midpoint between the two distance sensing parts 61 is taken as the sampling point.

[0053] A correction and positioning method, applied to a correction and positioning component, includes the following steps:

[0054] S1. Use the first correction cylinder 311 to press the single crystal silicon rod against the buffer plate 33;

[0055] S2, Control the first corrective cylinder 311 to retract;

[0056] S3. The sliding table 4 assembly is moved using the monitoring data generated by the distance sensing sensor 6.

[0057] S4. After reaching the preset position, stop the slide table 4 assembly and use the second correction cylinder 321 to push the single crystal silicon rod against the buffer plate 33.

[0058] As described above, the correction and positioning method is mainly divided into two stages: the first stage uses the first correction cylinder 311 to perform preliminary correction on the single crystal silicon rod, and the second stage, under the control of the distance sensing sensor 6, controls the second correction cylinder 321 to perform secondary correction on the single crystal silicon rod at the corresponding position and complete the positioning.

[0059] Further, step S3 specifically includes:

[0060] S31. Obtain the cutting distance Z, the length Y of the single crystal silicon rod, and the distance X between the distance sensing sensor 6 and the operating component;

[0061] S32. After performing defect balance calculations on the single-crystal silicon rod, obtain the relative distance U between the distance sensing sensor 6 and the zero-position of the loading.

[0062] S33. According to the formula: W=U+X+ZY, the absolute travel distance W of the slide 4 is calculated;

[0063] S34, control the slide 4 to travel a distance W from the zero position.

[0064] As described above, the fixed values ​​of the correction component 3 are obtained in advance, including the required cutting distance Z of the monocrystalline silicon rod, the length Y of the monocrystalline silicon rod, and the distance X between the distance sensing sensor 6 and the operating component. At the same time, the monocrystalline silicon rod is balanced by the distance sensing sensor 6 to obtain the relative distance U between the distance sensing sensor 6 and the zero position of the loading. Then, the absolute travel distance W to the slide table 4 is calculated according to the formula. Finally, the slide table 4 is controlled to travel a distance W from the zero position, that is, to transport the monocrystalline silicon rod to the cutting position. Here, the zero position is the starting position for placing the monocrystalline silicon rod on the support rail. In one embodiment of the present invention, the zero position is located at the head of the ball support rail.

[0065] Further, step S32 specifically includes:

[0066] When the distance sensing sensor 6 detects the tail of the monocrystalline silicon rod on one side, record the travel distance U1 of the slide table 4 at this time; when the distance sensing sensor 6 detects the tail of the monocrystalline silicon rod on the other side, record the travel distance U2 of the slide table 4 at this time.

[0067] Using the formula: The relative distance U between the distance sensing sensor 6 and the zero position of the feeding is calculated.

[0068] As described above, in order to balance the error caused by defects on the end face of the monocrystalline silicon rod, the distance sensing sensors 6 on both sides of the monocrystalline silicon rod are used to monitor the tail of the rod, and the end face with defects or tilting is used to perform balance calculation. The result of the balance calculation is used as the relative distance U between the distance sensing sensor 6 and the zero position of the loading. The adjacent surface is the side of the monocrystalline silicon rod closest to the distance sensing sensor, and the end of the monocrystalline silicon rod away from the zero position is regarded as the tail of the monocrystalline silicon rod.

[0069] This invention provides a correction and positioning component and method, mainly applied to the positioning and correction of single-crystal silicon rods before processing. The following is a detailed description with reference to embodiments:

[0070] Please refer to Figures 1 to 9Embodiment 1 of the present invention is as follows: a correction and positioning component applied to the correction and positioning of a single crystal silicon rod, comprising an installation platform 1, a support rail 2, and a correction component 3, wherein the support rail 2 and the correction component 3 are both disposed on the installation platform 1; the support rail 2 includes a ball bearing support rail 21 and a flexible support rail 22 assembled and connected along the axial direction of the rail; the correction component 3 includes a first correction component 31 and a second correction component 32; the first correction component 31 includes a first correction cylinder 311 and a first positioning plate 312 positioned opposite each other, and the ball bearing support rail 21 is located between the first correction cylinder 311 and the first positioning plate 312; the second correction component 32 includes a second correction cylinder 321 and a second positioning plate 322 positioned opposite each other, and the flexible support rail 22 is located between the second correction cylinder 321 and the second positioning plate 322.

[0071] In this embodiment, a correction and positioning component is provided. The ball bearing support rail 21 reduces the friction generated by the monocrystalline silicon rod during the correction process. At the same time, the first correction component 31 is used to perform preliminary correction on the monocrystalline silicon rod. After the preliminary positioning is completed, the position of the monocrystalline silicon rod is finely adjusted and clamped by the second correction component 32, thereby completing the final positioning, reducing the material loss of the monocrystalline silicon rod during the correction process while achieving the correction and positioning effect.

[0072] Preferably, in this embodiment, the ball bearing support rail 21 includes a ball bearing fixing plate and balls. The upper surface of the ball bearing fixing plate is provided with ball bearing fixing grooves at fixed intervals along the axial direction. The balls are placed in the ball bearing fixing grooves and protrude from the upper surface of the ball bearing fixing plate.

[0073] Please refer to Figures 1 to 9 The second embodiment of the present invention is as follows: Based on the first embodiment, the installation platform 1 is provided with an installation groove 11, and the first positioning plate 312 and the second positioning plate 322 are detachably connected to the installation platform 1 through the installation groove 11.

[0074] The axis of the mounting groove 11 is parallel to the axis of the support rail 2; multiple mounting grooves 11 are provided, and the mounting grooves 11 are arranged sequentially at a first preset interval along the direction perpendicular to the axis of the support rail 2;

[0075] The projection perpendicular to the axis of the support rail is the first projection plane. On the first projection plane, the horizontal distance between the installation position of the first positioning plate and the center of the support rail is less than the horizontal distance between the installation position of the second positioning plate and the center of the support rail.

[0076] In this embodiment, to accommodate monocrystalline silicon rods of different sizes, the positioning plate is detachably connected to the mounting platform 1 via the mounting groove 11. At the same time, the axis of the mounting groove 11 is parallel to the axis of the support rail 2 and multiple mounting grooves 11 are arranged sequentially at a first preset interval along a direction perpendicular to the axis of the support rail 2 (i.e., multiple mounting grooves 11 for positioning plates are provided in the width direction of the monocrystalline silicon rod). Thus, the positioning plate can be placed in different mounting grooves 11 according to the actual width of the monocrystalline silicon rod, thereby ensuring that the center of gravity of the monocrystalline silicon rod is always located on the support rail 2 and preventing the monocrystalline silicon rod from falling off the support rail 2 during the correction and positioning process.

[0077] Meanwhile, to prevent wear between the monocrystalline silicon rod and the positioning plate, the horizontal distance between the installation position of the first positioning plate and the center of the support rail is less than the horizontal distance between the installation position of the second positioning plate and the center of the support rail. The principle is as follows: after the monocrystalline silicon rod is initially positioned by the first straightening cylinder 311 and the first positioning plate 312, the side of the monocrystalline silicon rod is in contact with the first positioning plate 312. In order to prevent the side of the monocrystalline silicon rod from colliding with or generating large friction with the second positioning plate 322 during transportation, which would cause damage to the monocrystalline silicon rod, the minimum distance between the second positioning plate 322 and the support rail 2 is controlled to be greater than the minimum distance between the first positioning plate 312 and the support rail 2.

[0078] Please refer to Figures 1 to 9 The third embodiment of the present invention is as follows: based on the second embodiment, the number of support rails 2 is greater than or equal to 2; it also includes a slide 4, which is disposed between the support rails 2, and the slide 4 is provided with a telescopic part, which is used to control the movement of the slide 4 in the vertical direction; both the first positioning plate 312 and the second positioning plate 322 are provided with buffer plates 33, and the installation positions of the buffer plates 33 are respectively opposite to the first correction cylinder 311 and the second correction cylinder 321.

[0079] In this embodiment, to accommodate monocrystalline silicon rods of different sizes and provide stable support, the number of support rails 2 is greater than or equal to two. This ensures that the center of gravity of the monocrystalline silicon rod falls on or between the support rails 2, preventing slippage or tipping. Simultaneously, to facilitate transportation of the monocrystalline silicon rod, a slide 4 is provided between the support rails 2. The slide 4 can both run along the axis of the support rail 2 and lift the monocrystalline silicon rod via a telescopic section, allowing it to detach from the support rails 2 during transportation and reducing friction. Furthermore, to prevent the monocrystalline silicon rod from colliding with the positioning plate under the action of the straightening cylinder, thus preventing damage, a buffer plate 33 is provided on the positioning plate at a position corresponding to the straightening cylinder to absorb inertial force. This eliminates the need to evenly distribute the buffer plate 33 across the entire positioning plate, saving materials and costs.

[0080] Please refer to Figures 1 to 9The fourth embodiment of the present invention is as follows: Based on the third embodiment, it further includes a feeding sensor 5 and a distance sensing sensor 6 disposed on the mounting platform 1; the feeding sensor 5 is located on one side of the support rail 2 and is opposite to the first correction cylinder 311; the distance sensing sensor 6 is located on both sides of the support rail 2 between the first correction cylinder 311 and the second correction cylinder 321.

[0081] The distance sensing sensor 6 has two distance sensing units 61 arranged at a fixed interval in the vertical direction.

[0082] In this embodiment, to improve the accuracy of the correction and positioning process, a feeding sensor 5 and a distance sensing sensor 6 are provided. The feeding sensor 5 is positioned opposite the first correction cylinder 311, and the first correction cylinder 311 is activated only when the feeding sensor 5 detects the presence of complete material. At the same time, for precise positioning, the distance sensing sensor 6 is provided to accurately sense the travel distance of the monocrystalline silicon rod and control the second correction cylinder 321 to clamp the monocrystalline silicon rod at a preset position. Preferably, the distance sensing sensor 6 has two distance sensing parts 61 at a fixed interval in the vertical direction. The principle is that, in order to prevent defects or tilting on the side of the detected monocrystalline silicon rod, which would cause a large error in distance sensing, the two distance sensing parts 61 in the vertical direction are used to simultaneously project and sense the side of the monocrystalline silicon rod. After obtaining the projected distance (the distance between the distance sensing part 61 and the side of the monocrystalline silicon rod), if the two are different, the average of the two projected distances is taken as the final projected distance, and the midpoint between the two distance sensing parts 61 is taken as the sampling point.

[0083] Please refer to Figures 1 to 9 Embodiment 5 of the present invention is: a correction and positioning method, applied to any one of the correction and positioning components in Embodiments 1 to 4 above, comprising the following steps:

[0084] S1. Use the first correction cylinder to press the single crystal silicon rod against the buffer plate;

[0085] S2, Control the first correction cylinder to retract;

[0086] S3. The sliding table assembly is moved using monitoring data generated by the distance sensing sensor.

[0087] S4. After reaching the preset position, stop the slide assembly and use the second correction cylinder to push the single crystal silicon rod against the buffer plate.

[0088] In this embodiment, the correction and positioning method is mainly divided into two stages: the first stage uses the first correction cylinder to perform preliminary correction on the monocrystalline silicon rod, and the second stage, under the control of the distance sensing sensor, controls the second correction cylinder to perform secondary correction on the monocrystalline silicon rod at the corresponding position and complete the positioning.

[0089] Please refer to Figures 1 to 9 Embodiment Six of the present invention is as follows: Based on Embodiment Five, step S3 specifically includes:

[0090] S31. Obtain the cutting distance Z, the length Y of the single crystal silicon rod, and the distance X between the distance sensing sensor and the operating component;

[0091] S32. After performing defect balance calculations on the single-crystal silicon rod, obtain the relative distance U between the distance sensing sensor and the zero-position of the loading.

[0092] S33. According to the formula: W=U+X+ZY, the absolute travel distance W of the slide is calculated;

[0093] S34. Control the slide to travel a distance W from the zero position.

[0094] Step S32 is as follows:

[0095] When the distance sensing sensor detects the tail of the monocrystalline silicon rod on one side, record the travel distance U1 of the slide table at this time; when the distance sensing sensor detects the tail of the monocrystalline silicon rod on the other side, record the travel distance U2 of the slide table at this time.

[0096] Using the formula: The relative distance U between the distance sensing sensor and the zero position of the material feed is calculated.

[0097] In this embodiment, fixed values ​​of the correction component are obtained in advance, including the required cutting distance Z of the monocrystalline silicon rod, the length Y of the monocrystalline silicon rod, and the distance X between the distance sensing sensor and the operating component. At the same time, the monocrystalline silicon rod is balanced by the distance sensing sensor to obtain the relative distance U between the distance sensing sensor and the zero position of the loading. Then, the absolute travel distance W to the slide is calculated according to the formula. Finally, the slide is controlled to travel a distance W from the zero position, that is, to transport the monocrystalline silicon rod to the cutting position.

[0098] Meanwhile, in order to balance the error caused by defects on the end face of the monocrystalline silicon rod, distance sensing sensors on both sides of the monocrystalline silicon rod are used to monitor the tail of the rod, and balance calculations are performed on the end face with defects or tilt. The result of the balance calculation is used as the relative distance U between the distance sensing sensor and the zero position of the feeding.

[0099] In summary, a correction and positioning component and method are provided, which divides the correction process into primary correction and secondary correction. The monocrystalline silicon rod is initially positioned by a first correction cylinder and a first positioning plate, and then the monocrystalline silicon rod is positioned secondary by a second correction cylinder and a second positioning plate. This reduces the stress on the monocrystalline silicon rod during the positioning process, prevents damage, and improves the positioning accuracy.
