Description

Technical Field

[0001] The present disclosure relates to the fields of semiconductor and photovoltaic technology, and in particular to a sheet material transfer device and a material conveying system. Background Art

[0002] With the development of photovoltaic technology, solar cells are widely used in various fields. Depending on the size requirements, the processing steps of solar cells may include cutting, so that the whole solar cell is cut into two halves. The cut halves are then transported to the subsequent processing steps, such as laser grooving and printing.

[0003] The two halves of a cut sheet need to be adjusted during transport. For example, if the corners of the full sheet are chamfered before cutting, the two halves may be mirror images. In some processing steps where this orientation is required, a robotic arm must align the two halves while handling them, ensuring that the chamfers are on the same side rather than mirror images. Currently, there is no device capable of adjusting the orientation of the halves. Utility Model Content

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0027] Figure 1 FIG2 is a schematic diagram of a material conveying system according to an embodiment of the present disclosure, wherein the direction indicated by arrow X is a first direction, and the direction indicated by arrow Y is a second direction. The first direction X and the second direction Y are perpendicular to each other in a horizontal plane and will not be emphasized separately in the following.

[0028] The present disclosure provides a sheet material transfer device, such as Figure 1 The sheet material transfer device 1 is applied to a material conveying system 10 having two or more processing positions. The sheet material transfer device 1 is configured to transport one or more sheet material groups 5 between different processing positions.

[0029] Optionally, the wafer group 5 may include two wafers spaced apart. That is, the wafer group 5 may be a whole solar silicon wafer (also known as a silicon wafer) before being cut, which is then divided into two halves after cutting. The silicon wafer may be, for example, a square wafer with chamfered corners, so that the two halves are arranged in a mirror-image arrangement after being cut.

[0030] The material conveying system 10 can be used for processes such as laser grooving and printing that require the placement direction of silicon wafers. For example, when the two cut halves of the wafer are transported to the laser grooving position, there is a requirement for the placement direction of the chamfers of the two halves of the wafer. The chamfers of the two halves of the wafer need to be on the same side, rather than in a mirrored arrangement. The sheet transfer device 1 is configured to be able to adjust the two halves of the wafer so that the placement direction of the chamfers is consistent during the process of transporting the two halves of the wafer to the laser grooving position. For ease of understanding, the embodiment of the present disclosure is described in detail using the material conveying system 10 for laser grooving as an example.

[0031] The material conveying system 10 includes a sheet conveying device, a processing device, and a sheet transfer device 1. The processing device may be a laser slotting device 3. The sheet conveying device includes an input device 2 and an output device 4. The input device 2, output device 4, and laser slotting device 3 are arranged in a U-shaped configuration around the sheet transfer device 1. Multiple processing stations can be located for the input device 2, output device 4, and laser slotting device 3, respectively. The input device 2 has a first processing station 21, the laser slotting device 3 has a second processing station 31, and the output device 4 has a third processing station 41. The input device 2 and output device 4 are symmetrically arranged on either side of the sheet transfer device 1 along a first direction X. The laser slotting device 3 is arranged on one side of the sheet transfer device 1 along a second direction Y. The input device 2 has a first conveying direction Q, and the output device 4 has a second conveying direction S. The first conveying direction Q and the second conveying direction S are opposite. The two halves of the same sheet group 5 move in opposite directions along the second direction Y on the input device 2 and output device 4, respectively.

[0032] The sheet group 5 includes a first half sheet 51 and a second half sheet 52 arranged at intervals. The first half sheet 51 and the second half sheet 52 of the sheet group 5 located in the input device 2 are arranged at intervals along a first direction X. The first half sheet 51 and the second half sheet 52 of the sheet group 5 located in the output device 4 are arranged at intervals along the first direction X. The first half sheet 51 and the second half sheet 52 of the sheet group 5 located in the laser slotting mechanism 3 are arranged at intervals along a second direction Y. The sheet transfer device 1 rotates about its own axis to transfer at least one sheet group 5 from the first processing station 21 to the second processing station 31 for laser slotting. It can also transfer at least one sheet group 5 from the second processing station 31 to the third processing station 41 to transfer the two laser slotted halves to the next process.

[0033] Optionally, the first conveying direction Q and the second conveying direction S are respectively parallel to the second direction Y, and the line connecting the center point of the first processing position 21 and the center point of the sheet material transfer device 1 and the line connecting the center point of the second processing position 31 and the center point of the sheet material transfer device 1 form a 90° angle, and the line connecting the center point of the second processing position 31 and the center point of the sheet material transfer device 1 and the line connecting the center point of the third processing position 41 and the center point of the sheet material transfer device 1 form a 90° angle. In other examples, if the material conveying system 10 is used for other processing techniques, it can also include a fourth processing position, a fifth processing position, etc., and the lines connecting the center points of adjacent processing positions and the center point of the sheet material transfer device 1 can also be arranged at non-zero angles such as 45°, 60°, etc. The sheet material transfer device 1 can enable the sheet group 5 to flow between different processing positions, without specific limitation. For ease of description, the sheet material transfer device 1 is described in detail in the embodiment of the present disclosure by taking the laser grooving process in which the line connecting the center points of adjacent processing positions and the center point of the sheet material transfer device 1 forms a 90° angle as an example.

[0034] Figure 2 Shown is a schematic diagram of a sheet material transfer device provided by an embodiment of the present disclosure in a first working state. Figure 3 Shown is a schematic diagram of a sheet material transfer device provided by an embodiment of the present disclosure in a second working state. Figure 4 Shown is a schematic diagram of a sheet material transfer device provided in one embodiment of the present disclosure. Figure 5 The figure shows a simple schematic diagram of a synchronous pulley group in a sheet material transfer device provided by an embodiment of the present disclosure moving from a first processing position to a second processing position. Figure 6 Shown Figure 4 A partial enlarged view of part A in the sheet material transfer device is shown. Figure 7 Shown Figure 4 A partial enlarged view of part B in the sheet material transfer device is shown.

[0035] The following describes an exemplary structure of the sheet transfer device 1 for transferring at least one sheet group 5 between the first processing station 21 and the second processing station 31 .

[0036] like Figures 2 to 6The sheet material transfer device 1 includes a fixed seat 11, a first fixed frame 12, one or more first adsorption components 13, a first drive component 15, one or more second adsorption components 14 and one or more second drive components 16. The fixed seat 11 is arranged at the center position of the U-shaped structure surrounded by the first processing position 21, the second processing position 31 and the third processing position 41. The first fixed frame 12 is rotatably connected to the fixed seat 11. The first adsorption component 13 is rotatably connected to the first fixed frame 12. The first adsorption component 13 is configured to take and place a half sheet in the sheet group 5. The first drive component 15 is arranged on the first fixed frame 12. The first drive component 15 is connected to the hinge point 13a of the first adsorption component 13, and drives the first adsorption component 13 to rotate in the horizontal plane with the hinge point 13a as the center to adjust the placement direction of the half sheet adsorbed by the first adsorption component 13. The second adsorption component 14 is movably connected to the first fixed frame 12, and the second adsorption component 14 is configured to take and place the other half sheet in the sheet group 5; the second driving component 16 is arranged on the first fixed frame 12, and each second driving component 16 is connected to more than one second adsorption component 14, and the second driving component 16 is configured to drive the second adsorption component 14 to move in the vertical direction, so that the half sheet adsorbed by the first adsorption component 13 and the half sheet adsorbed by the second adsorption component 14 can be staggered in the vertical direction.

[0037] Illustratively, two cut halves of at least one sheet group 5 enter the first processing station 21 via the input device 2 in the first conveying direction Q. At this time, the chamfers of the first half sheet 51 and the second half sheet 52 of the same sheet group 5 located at the first processing station 21 are arranged opposite to each other in the first direction X. In a first working state, the first fixed frame 12 rotates relative to the fixed base 11 until the first suction assembly 13 and the second suction assembly 14 are located above the first processing station 21, with the first suction assembly 13 located above the second half sheet 52 and the second suction assembly 14 located above the first half sheet 51. The first suction assembly 13 and the second suction assembly 14 are capable of suctioning the first half sheet 51 and the second half sheet 52 of at least one sheet group 5 at the first processing station 21. The first fixed frame 12 rotates relative to the fixed base 11 to a second working state. In the second working state, the first suction assembly 13 and the second suction assembly 14 place the suctioned first half sheet 51 and the second half sheet 52 on the second processing station 31. During the transfer process from the first working state to the second working state, the second driving assembly 16 can drive the second adsorption assembly 14 to rise or fall in the vertical direction, so that the first half sheet 51 and the second half sheet 52 are staggered in the vertical direction. The first driving assembly 15 then drives the first adsorption assembly 13 to rotate about the hinge point 13a, so that the second half sheet 52 adsorbed by the first adsorption assembly 13 can be adjusted in direction, so that the chamfers of the first half sheet 51 and the second half sheet 52 finally placed on the second processing position 31 are adjusted to be on the same side. That is, at the second processing position 31, the chamfers of the first half sheet 51 and the second half sheet 52 are both located on the side facing the sheet transfer device 1 in the second direction Y.

[0038] The sheet material transfer device 1 provided by the embodiment of the present disclosure utilizes the first adsorption component 13 and the second adsorption component 14 to respectively take and place two half sheets of the same sheet material group 5. In the process of the first adsorption component 13 and the second adsorption component 14 adsorbing the two half sheets to transfer them to the corresponding processing position, the second driving component 16 can drive the second adsorption component 14 to drive one of the half sheets to be misaligned with the other half sheet in the height direction, so that the first driving component 15 can drive the first adsorption component 13 to drive the half sheet to rotate, thereby realizing the adjustment of the placement direction of the two half sheets of the same sheet material group 5 during the transfer process, and thereby making the placement direction of the chamfers of the two half sheets transferred to the corresponding processing position consistent.

[0039] It is understandable that the fixing seat 11 can be configured as a hollow box structure, and the interior of the box can be used to arrange electronic devices such as a power supply.

[0040] Optionally, a first rotating shaft 17 is rotatably connected to the rotation center 11a of the fixed base 11, and the first fixed frame 12 is fixedly connected to the first rotating shaft 17. The rotation of the first rotating shaft 17 can drive the first fixed frame 12 to rotate about the center of the first rotating shaft 17. It is understood that the straight-line distance from the center of the first rotating shaft 17 to the center of any processing position is equal.

[0041] In some embodiments, the first drive assembly 15 includes a drive member 151 and a synchronous pulley assembly 152. The drive member 151 is connected to the fixed base 11 and is configured to drive the first fixed frame 12 to rotate in the horizontal plane by a first preset angle a. One or more first adsorption assemblies 13 are rotatably connected to the first fixed frame 12 via the synchronous pulley assembly 152. When the drive member 151 drives the first fixed frame 12 to rotate by the first preset angle a, the synchronous pulley assembly 152 simultaneously drives the first adsorption assembly 13 to rotate about the hinge point 13a by a second preset angle b. Utilizing the design of the transmission matching structure, a single drive source (drive member 151) can simultaneously achieve the rotation of the first fixed frame 12 around the axis of the first rotating shaft 17 to the corresponding processing position and the rotation of the first adsorption assembly 13 about the hinge point 13a to adjust the direction of the second half 52. This matching structure is simple, energy-saving, and has higher precision and better stability in controlling the rotation angle.

[0042] Optionally, a second rotating shaft 18 is provided at the hinge point 13a of the first adsorption assembly 13, and the second rotating shaft 18 is rotatably connected to the first fixed frame 12. A synchronous pulley assembly 152 is respectively connected to the first rotating shaft 17 and the second rotating shaft 18, so that when the driving member 151 drives the first rotating shaft 17 to rotate, the synchronous pulley assembly 152 drives the second rotating shaft 18 to rotate, so that the first half sheet 51 and the second half sheet 52 can be transported from the first processing station 21 to the second processing station 31 while adjusting the placement direction of the second half sheet 52.

[0043] Optionally, the center point of an adjacent processing position and the center point of the fixed seat 11 have a first connecting line, and the center point of another processing position and the center point of the fixed seat 11 have a second connecting line, and there is a first preset angle a between the first connecting line and the second connecting line, which is the angle at which the first fixed frame 12 rotates in the horizontal plane during transportation. The first preset angle a can specifically be 90°, and the second preset angle b is 180°, so that the placement direction of the chamfers of the two half-sheets is adjusted to be consistent when they are transferred from one processing position to another adjacent processing position. In other examples, the first preset angle a ranges from 20° to 160°. For example, the first preset angle a can also be 45°, 60°, etc., and the second preset angle b can be 40°, 90°, etc., and is adaptively adjusted according to the arrangement of the processing positions and the different placement direction requirements of the two half-sheets, without specific limitation.

[0044] Specifically, the synchronous pulley group 152 includes a first synchronous pulley 1521, one or more second synchronous pulleys 1522 and a synchronous belt 1523. The first synchronous pulley 1521 is connected to the rotation center 11a of the fixed seat 11, and the first synchronous pulley 1521 has first gear teeth; each second synchronous pulley 1522 is connected to a first adsorption component, and the second synchronous pulley 1522 has second gear teeth, and the number of second gear teeth is greater than the number of first gear teeth; the synchronous belt 1523 is meshed and connected with the first synchronous pulley 1521 and the second synchronous pulley 1522. By means of the meshing cooperation of the first synchronous wheel 1521, the second synchronous wheel 1522 and the synchronous belt 1523, the first fixed frame 12 can be accurately controlled to rotate 90° around the axis of the first rotating shaft 17, while each first adsorption component 13 can rotate 180° around the axis of the second rotating shaft 18, thereby realizing the second half sheet 52 adsorbed by the first adsorption component 13 to rotate 180° in the horizontal plane, thereby adjusting the chamfer placement direction of the two half sheets of the sheet group 5 from mirror image to the same direction.

[0045] It is understandable that the number of the first gear teeth of the first synchronous gear 1521 and the number of the second gear teeth of the second synchronous gear 1522 can be obtained by calculation and can be calculated and selected according to actual conditions.

[0046] In some embodiments, the first synchronous wheel 1521 can be fixedly connected to the rotation center 11a of the fixed base 11, that is, the first synchronous wheel 1521 can be hinged to the first rotating shaft 17, and the two are coaxial. When the driving member 151 drives the first rotating shaft 17 to rotate the first preset angle a around the rotation center 11a, the hinged first synchronous wheel 1521 is fixed, and the rotation of the first fixed frame 12 forces the synchronous belt 1523 to rotate accordingly, so that the synchronous belt 1523 moves relative to the first synchronous wheel 1521, and then the synchronous belt 1523 drives the second synchronous wheel 1522 to rotate the second preset angle b. For example, Figure 5 For ease of understanding, the solid-line synchronous pulley assembly 152 in the figure indicates that it is currently in the first processing position 21, and the dashed-line synchronous pulley assembly 152 indicates that it can reach the second processing position 31 after rotating through a first preset angle a. Assuming that the angular velocity and number of first teeth of the first synchronous pulley 1521 are W1 and Z1, respectively, and the angular velocity and number of second teeth of the second synchronous pulley 1522 are W2 and Z2, respectively, the angular velocity of the first fixed frame 12 revolving about the rotation center 11a of the first rotating shaft 17 (rotating from the first processing position 21 to the second processing position 31) is Wh, which is also the angular velocity of the synchronous belt 1523 revolving about the rotation center 11a of the first rotating shaft 17. The transmission characteristics of the synchronous belt 1523 indicate that when the first synchronous pulley 1521 is stationary, the second synchronous pulley 1522 rotates in the opposite direction of the first fixed frame 12. The following formula can be derived from the calculation:

[0047] In an alternative embodiment, the first synchronous wheel 1521 can be directly rotatably connected to the first rotating shaft 17. When the driving member 151 drives the first rotating shaft 17 to rotate by the first preset angle a, the first synchronous wheel 1521 can also synchronously rotate by the first preset angle a. The rotation of the first synchronous wheel 1521 is transmitted through the meshing synchronous belt 1523, so that the second synchronous wheel 1522 drives the second rotating shaft 18 to rotate by the second preset angle b. At this time, the orbital direction of the first fixed frame 12 is the same as the rotation direction of the second synchronous wheel 1522. It is understood that the transmission ratio between the first synchronous wheel 1521 and the second synchronous wheel 1522 can be adaptively adjusted according to needs and is not specifically limited.

[0048] In some optional embodiments, the synchronous pulley assembly 152 further includes one or more tensioning pulleys 1524 rotatably connected to the first fixed frame 12, and configured to tension the synchronous belt 1523; and / or one or more idler pulleys 1525 rotatably connected to the first fixed frame 12, and configured to support the synchronous belt 1523. The provision of the tensioning pulleys 1524 and the idler pulleys 1525 further improves the stability and accuracy of the transmission of the synchronous driving pulley assembly 152.

[0049] In some embodiments, the second drive assembly 16 includes a cylinder 161 and a connecting portion 162. The cylinder 161 is connected to the first fixing frame 12, and the connecting portion 162 is connected to the output end of the cylinder 161. The connecting portion 162 is also connected to the second adsorption assembly 14. The cylinder 161 is configured to push the connecting portion 162 in a vertical direction to drive the second adsorption assembly 14 to rise or fall. It is understood that the distance by which the cylinder 161 drives the second adsorption assembly 14 to rise or fall can be adjusted according to actual conditions, for example, to 5 mm, 10 mm, 20 mm, etc., without specific limitation, as long as the first half of the sheet 51 does not collide with the second half of the sheet 52 during the horizontal rotation of the second half of the sheet 52 grasped by the first adsorption assembly 13.

In the embodiment of the present disclosure, the sheet material transfer device 1 is capable of simultaneously transporting two sheet material groups 5, that is, the first processing position 21 of the input device 2 carries two sheet material groups 5 spaced apart along the second direction Y. In the first working state, the first adsorption components 13 are arranged in two spaced-apart manner along the second direction Y, so as to correspond to the two second halves 52 of the two sheet material groups 5, respectively.

[0055] Optionally, one synchronous pulley set 152 can simultaneously connect two second rotating shafts 18 and two first rotating shafts 17 to achieve synchronous transmission.

The second drive component 16 is connected to the connecting rod so that the second drive component 16 can drive the two second adsorption components 14 to rise or fall simultaneously in the vertical direction, without specific limitation.

[0057] The following describes an exemplary structure of the sheet material transfer device 1 for transferring at least one sheet material group 5 between the second processing station 31 and the third processing station 41 .

[0058] In some embodiments, the sheet transfer device 1 also includes a second fixed frame 19, one or more third adsorption components 191 and one or more fourth adsorption components 192, the second fixed frame 19 is fixedly connected to the first fixed frame 12; one or more third adsorption components 191 are connected to the second fixed frame 19, and the third adsorption component 191 is configured to take and place one half sheet in the sheet group 5; one or more fourth adsorption components 192 are connected to the second fixed frame 19, and the fourth adsorption component 192 is configured to take and place the other half sheet in the sheet group 5.

Even if one of the third adsorption component 191 and the fourth adsorption component 192 can move up and down and the other can rotate around itself, it can be adaptively adjusted according to actual conditions without specific limitation.

The fourth adsorption assembly 192 includes a fourth fixed seat 1921, which is fixedly connected to the second fixed frame 19; a fourth suction cup 1922 is connected to the fourth fixed seat 1921, and the fourth suction cup 1922 is configured to adsorb the other half of the sheet; a fourth adjustment member 1923 is connected between the fourth fixed seat 1921 and the fourth suction cup 1922, and the fourth adjustment member 1923 is configured to adjust the inclination angle of the fourth suction cup 1922 relative to the horizontal plane, so that the surface of the half sheet adsorbed by the fourth suction cup 1922 is parallel to the horizontal plane.
