At the same time, the connecting rod assembly can rotate with a second mounting point as the center, and drive the grabbing assembly to rotate with a third mounting point as the center, so that while the bracket assembly drives the grabbing assembly to rotate to different workstations, the connecting rod assembly drives the grabbing assembly to rotate to adjust the placement direction of the sheet material.

DETAILED DESCRIPTION
[0028] 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.
[0029] Figure 1 FIG2 is a schematic diagram of a sheet material transport mechanism in a sheet material transmission 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 and will not be described in detail later.
[0030] The present disclosure provides a sheet material transport mechanism. Figure 1 The sheet material transport mechanism 1 is applied to a sheet material transmission system 10 , which has two or more working stations. The sheet material transport mechanism 1 is configured to transport sheets between different working stations.
[0031] Optionally, the sheet material may be a solar cell. In the embodiment of the present disclosure, for ease of description, the solar cell is set to be rectangular, and the rectangular solar cell is referred to as a "substrate" without specific limitation.
[0032] The sheet material transport system 10 can be used for processes such as laser grooving and printing that require the placement direction of the substrate 5. For ease of understanding, the embodiment of the present disclosure is described in detail using the sheet material transport system 10 used for laser grooving as an example.
[0033] The sheet material transport system 10 includes an input mechanism 2, an output mechanism 4, a laser slotting mechanism 3, and a sheet material handling mechanism 1. The input mechanism 2, the laser slotting mechanism 3, and the output mechanism 4 are arranged in a U-shaped configuration around the sheet material handling mechanism 1. The input mechanism 2 has a first working station 21, the laser slotting mechanism 3 has a second working station 31, and the output mechanism 4 has a third working station 41. The input mechanism 2 and the output mechanism 4 are symmetrically arranged on either side of the sheet material handling mechanism 1 along a first direction X, while the laser slotting mechanism 3 is arranged on one side of the sheet material handling mechanism 1 along a second direction Y. The sheet material handling mechanism 1 is configured to transport substrates 5 from the first working station 21 to the second working station 31 of the laser slotting mechanism 3 for processing such as imaging and laser slotting. Furthermore, the sheet material handling mechanism 1 is configured to transport substrates 5 that have been laser slotted at the second working station 31 to the third working station 41. The substrates 5 at the first working station 21 are placed in the same orientation as the substrates 5 at the third working station 41. For example, the first end 51 of the substrate 5 placed at the first workstation 21 is located on the side facing the second workstation 31 in the first direction X. When the substrate 5 is transported from the first workstation 21 and the second workstation 31 to the third workstation 41 through the sheet transporting mechanism 1, the first end 51 of the substrate 5 located at the third workstation 41 is also facing the second workstation 31 in the first direction X, which means that the substrate 5 is placed in the same direction in the first workstation 21 and the third workstation 41.
[0034] In some optional embodiments, the substrate 5 to be transported by the sheet transport system 10 can be a whole substrate 5 or two half-sheets. The input mechanism 2, the output mechanism 4, the sheet transport mechanism 1, and the laser slotting mechanism 3 can be adaptively adjusted according to actual needs, and no further details are given. For ease of understanding, the present disclosure uses a whole substrate 5 as an example for description.
[0035] Figure 2 Shown is a schematic diagram of a sheet material transporting mechanism provided by an embodiment of the present disclosure in a first working state. Figure 3 Shown is a schematic diagram of a sheet material transporting mechanism provided by an embodiment of the present disclosure in a second working state. Figure 4 Shown is a top view of a sheet material transporting mechanism provided by an embodiment of the present disclosure in a first working state. Figure 5 FIG2 is a top view of a sheet material transport mechanism provided by an embodiment of the present disclosure in a second working state. It is understood that for ease of description, Figure 4 The state of the sheet material conveying mechanism 1 when the grabbing assembly 14 is located above the second working position 31 is regarded as the first working state. Figure 5The state of the sheet conveying mechanism 1 when the grabbing component 14 is located above the third working position 41 is taken as the second working state. In other examples, the first working state may also be the state of the sheet conveying mechanism 1 when the grabbing component 14 is located above the first working position 21, and the second working state may also be the state of the sheet conveying mechanism 1 when the grabbing component 14 is located above the second working position 31, etc., without specific limitation.
[0036] The following describes the specific structure of the sheet conveying mechanism 1 when the sheet conveying mechanism 1 is in the first operating state.
[0037] like Figure 2 and Figure 3 The sheet transport mechanism 1 includes a base 11, a bracket assembly 13, a grabbing assembly 14 and a connecting rod assembly 15. The bracket assembly 13 is rotatably connected to the first mounting point 1a of the base 11. The grabbing assembly 14 includes at least one grabbing group 14a. The grabbing group 14a is rotatably connected to the end of the bracket assembly 13 away from the base 11 and is driven by the bracket assembly 13 to rotate around the first mounting point 1a as the center, so as to drive the grabbing assembly 14 to move to any working position to pick up and place the substrate 5; the connecting rod assembly 15 includes at least one connecting rod group 15a. One end of each connecting rod group 15a is rotatably connected to the second mounting point 1b of the base 11, and the other end is connected to the third mounting point 1c of a grabbing group 14a; wherein, when the bracket assembly 13 drives the grabbing assembly 14 to rotate synchronously around the first mounting point 1a as the center, the connecting rod group 15a rotates around the second mounting point 1b as the center, and can drive the grabbing group 14a to rotate around the third mounting point 1c as the center to adjust the placement direction of the substrate 5 on the grabbing assembly 14.
[0038] The rotatable support assembly 13 is used to drive the gripping assembly 14 to rotate between the first working position 21, the second working position 31, and the third working position 41, with the first mounting point 1a as the center. This allows the gripping assembly 14 to move to the corresponding working position to pick up and place the substrate 5. Simultaneously, the connecting rod assembly 15a can rotate with the second mounting point 1b as the center, driving the gripping assembly 14a to rotate with the third mounting point 1c as the center. As the support assembly 13 drives the gripping assembly 14 to rotate to different working positions, the connecting rod assembly 15 drives the gripping assembly 14a to rotate to adjust the placement direction of the substrate 5. The provision of the connecting rod assembly 15 links the rotation angle of the gripping assembly 14a with the rotation angle of the support assembly 13, facilitating more stable and accurate adjustment of the placement direction of the substrate 5.
[0039] In addition, the movement of the connecting rod assembly 15 depends on the rotation of the bracket assembly 13. It is a passive adjustment component and does not require the installation of additional drive motors or other structures that require active drive, thereby saving costs. There is no need to consider the wear or damage of the drive motor over a long period of use, which may cause the control adjustment of the substrate 5 to have low placement accuracy and poor stability.
[0040] It is understandable that the base 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. A rotating assembly 12 is mounted on the base 11, and the rotating assembly 12 includes a drive shaft 121 and a drive member 122. The drive member 122 can be specifically arranged inside the box. The drive shaft 121 is rotatably mounted at the first mounting point 1a of the base 11, and the output end of the drive member 122 is connected to the drive shaft 121. The drive member 122 can drive the drive shaft 121 to move so that the drive shaft 121 can rotate in the horizontal plane. Among them, the straight-line distances between the two or more working positions and the first mounting point 1a are equal. For example, the linear distance between the center of the first working station 21 and the first mounting point 1a is L1, the linear distance between the center of the second working station 31 and the first mounting point 1a is L2, and L1 is equal to L2. Furthermore, the linear distance between the center of the third working station 41 and the first mounting point 1a is L3, and L1 is equal to L3. This allows the gripping assembly 14 to rotate between the three working stations with the drive shaft 121 at the first mounting point 1a as the center, thereby transporting the substrate 5 to the corresponding working station. Optionally, the driving member 122 can be a motor, which is not specifically limited.
[0041] In some embodiments, as Figure 4 and Figure 5The rotation direction of the support assembly 13 about the first mounting point 1a is the same as the rotation direction of the gripping assembly 14a about the third mounting point 1c. The angle of rotation of the gripping assembly 14 about the first mounting point 1a driven by the support assembly 13 is a first angle a, and the angle of rotation of the gripping assembly 14 about the third mounting point 1c driven by the connecting rod assembly 15a is a second angle b. The first angle a and the second angle b are the same. Specifically, in the first working state, the gripping assembly 14 is in the second working position 31 to pick up and place the substrate 5. At this time, the first end 51 of the substrate 5 is facing the sheet transport mechanism 1 in the second direction Y. After the driving member 122 drives the bracket assembly 13 to rotate clockwise by a first angle a of 90° about the first mounting point 1a, the gripping assembly 14 rotates to be located above the third working position 41. Furthermore, during the rotation from the second working position 31 to the third working position 41, the connecting rod assembly 15a rotates about the second mounting point 1b, causing the gripping assembly 14a to rotate clockwise by a second angle b of 90° about the third mounting point 1c, so that the first end 51 of the substrate 5 on the third working position 41 is located along the first direction X at the end facing the laser slotting mechanism 3. It will be understood that the first angle a and the second angle b may vary depending on the angle between adjacent working positions and are not specifically limited thereto.
[0042] It is understood that the gripping assembly 14 rotatably connected to the support assembly 13 may include one gripping group 14a, and one gripping group 14a may be used to pick up and place the substrate 5 on the corresponding work position, or the gripping assembly 14 rotatably connected to the support assembly 13 may include two or more gripping groups 14a, without specific limitation. Figure 4 In the embodiment of the present disclosure, the grabbing assembly 14 rotatably connected to the bracket assembly 13 includes two grabbing groups 14a, so as to realize the simultaneous transportation of multiple substrates 5 and improve the transportation efficiency. In the first working state, the two grabbing groups 14a are arranged at intervals along the first direction X, and the bracket assembly 13 includes a first bracket 131. Each grabbing group 14a is provided with a rotating shaft 14b at the third mounting point 1c and is rotatably connected to the first bracket 131 through the rotating shaft 14b. One end of each connecting rod group 15a is fixedly connected to a rotating shaft 14b. The first bracket 131 is configured as a T-shaped bracket, that is, it includes a first rod and a second rod arranged perpendicular to each other, the first rod is parallel to the first direction X, and the second rod is parallel to the second direction Y. The two grabbing groups 14a are respectively connected to the second rod symmetrically with respect to the first rod through the rotating shaft 14b provided at the third mounting point 1c, and the first rod is fixedly connected to the driving shaft 121.
[0043] It is understandable that the first rod and the second rod of the first bracket 131 can be set as an integrally formed T-shaped structure, and the second rod can be integrally formed or welded with the driving shaft 121 to improve the strength of the structure.
[0044] In some embodiments, the second mounting point 1b of the base 11 is fixedly connected to a fixed shaft 111, and the straight-line distances between the second mounting point 1b and two adjacent workstations are different. It is understandable that the number of connecting rod groups 15a can be the same as the number of grabbing groups 14a. In the embodiment of the present disclosure, two connecting rod groups 15a can also be provided, and both connecting rod groups 15a are connected to the fixed shaft 111. For example, the straight-line distance from the center of one adjacent workstation to the second mounting point 1b is L4, and the straight-line distance from the center of another workstation to the second mounting point 1b is L5, and L4 is not equal to L5, so that when the connecting rod group 15a rotates around the second mounting point 1b, it can drive the grabbing group 14a to rotate around the third mounting point 1c.
[0045] For example, the third mounting point 1c of each grabbing group 14a includes a rotating shaft 14b, which is rotatably connected to the second rod, so that the two grabbing groups 14a are spaced apart in the first direction X. Each connecting rod group 15a includes a connecting rod 151a, a hinge shaft 152a, and a push rod 153a. One end of the connecting rod 151a is fixedly connected to the rotating shaft 14b located at the third mounting point 1c of the grabbing group 14a; the other end of the connecting rod 151a is rotatably connected to the hinge shaft 152a; one end of the push rod 153a is fixedly connected to the hinge shaft 152a, and the other end is rotatably connected to the fixed shaft 111. The center distance between the drive shaft 121 and the fixed shaft 111 is equal to the center distance between the rotating shaft 14b and the hinge shaft 152a. By setting the center distances between the axes to be equal, when the driving member 122 drives the drive shaft 121 to rotate, the grabbing groups 14a can rotate synchronously by the same angle.
[0046] In the first working state, the connecting rods 151a in the two connecting rod groups 15a at the same working position extend in a direction perpendicular to the arrangement direction of the two or more grabbing groups 14a at the same working position. When the drive shaft 121 drives the bracket assembly 13 to rotate horizontally to the second working state of the sheet material transporting mechanism 1, the connecting rods 151a in the two connecting rod groups 15a at the same working position extend in a direction parallel to the arrangement direction of the two or more grabbing groups 14a at the same working position. A first angle p is formed between the connecting rod 151a and the push rod 153a in one connecting rod group 15a, and a second angle w is formed between the connecting rod 151a and the push rod 153a in the other connecting rod group 15a. The first angle p and the second angle w are complementary angles. The two connecting rod groups 15a can simultaneously adjust the placement direction of the substrates 5 on the two grabbing groups 14a. While being able to simultaneously transport multiple substrates 5, the placement direction of the multiple substrates 5 being transported can be accurately and stably adjusted, and the adjusted placement directions are the same.
[0047] Figure 6 Shown is a top view of a sheet material transporting mechanism provided by another embodiment of the present disclosure in a first working state. Figure 7Shown is a top view of a sheet material transporting mechanism provided by another embodiment of the present disclosure in a second working state. Figure 8 Shown is a side view of a sheet material transporting mechanism provided in accordance with an embodiment of the present disclosure.
[0048] In some embodiments, the sheet material transport mechanism 1 includes the following Figure 4 and Figure 5 Based on the structure in FIG, the bracket assembly 13 may further include a second bracket 132, with the central axis of the first bracket 131 and the central axis of the second bracket 132 forming a 90° angle in the horizontal plane. Each grabbing group 14a is provided with a rotating shaft 14b at the third mounting point 1c. The two or more grabbing groups 14a are rotatably connected to the first bracket 131 and the second bracket 132 via the rotating shafts 14b, respectively. The two or more connecting rod groups 15a have one end rotatably connected to the second mounting point 1b, and the other end fixedly connected to the two or more rotating shafts 14b.
[0049] It is understood that the second bracket 132 can be configured as a T-shaped structure similar to the first bracket 131, and the first bracket 131 and the second bracket 132 can be configured as an integral L-shaped structure to improve support stability and strength. In addition, a counterweight 133 can be provided at the connection between the first bracket 131 and the second bracket 132 to further improve the stability and strength of the first bracket 131 and the second bracket 132 in supporting the grab assembly 14.
[0050] Specifically, the grabbing assembly 14 provided on the first bracket 131 includes a first grabbing group 141 and a second grabbing group 142. The first grabbing group 141 has a first rotating shaft 1411 at the third mounting point 1c, and the first rotating shaft 1411 is rotatably connected to the second rod; the second grabbing group 142 has a second rotating shaft 1421 at the third mounting point 1c, and the second rotating shaft 1421 is rotatably connected to the second rod, and the second grabbing group 142 is located on one side of the first grabbing group 141 in the first direction X; the connecting rod assembly 15 includes The first link group 151 and the second link group 152 have one end fixedly connected to the second rotating shaft 1411 and the other end rotatably connected to the fixed shaft 111; the second link group 152 has one end fixedly connected to the second rotating shaft 1421 and the other end rotatably connected to the fixed shaft 111. While the drive shaft 121 rotates the support assembly 13 in the horizontal plane, the first link group 151 and the second link group 152 can drive the first grabbing group 141 and the second grabbing group 142 to rotate synchronously. The first link group 151 and the second link group 152 can simultaneously adjust the placement direction of the substrates 5 on the two grabbing groups 14a, ensuring that multiple substrates 5 can be transported simultaneously while accurately and stably adjusting the placement direction of the multiple substrates 5 being transported, and the adjusted placement directions are the same.
[0051] In some embodiments, the first link assembly 151 includes a first link 1511, a first hinge shaft 1512, and a first push rod 1513. One end of the first link 1511 is fixedly connected to the first rotating shaft 1411; the other end of the first link 1511 is rotatably connected to the first hinge shaft 1512; one end of the first push rod 1513 is fixedly connected to the first hinge shaft 1512, and the other end is rotatably connected to the fixed shaft 111. The second link assembly 152 includes a second link 1521, a second hinge shaft 1522, and a second push rod 1523. One end of the second link 1521 is fixedly connected to the second rotating shaft 1421; the other end of the second link 1521 is rotatably connected to the second hinge shaft 1522; one end of the second push rod 1523 is fixedly connected to the second hinge shaft 1522, and the other end is rotatably connected to the fixed shaft 111. In the first working state, the first connecting rod group 151 and the second connecting rod group 152 are symmetrically arranged relative to the first rod, the extension direction of the first connecting rod 1511 and the extension direction of the second connecting rod 1521 are both perpendicular to the first direction X, and the driving shaft 121 drives the bracket assembly 13 to rotate in the horizontal plane to the second working state. The extension direction of the first connecting rod 1511 and the extension direction of the second connecting rod 1521 are perpendicular to the first direction X, and the first angle p between the first connecting rod 1511 and the first push rod 1513 is different from the second angle w between the second connecting rod 1521 and the second push rod 1523. In the process of the rotation of the driving shaft 121 to drive the bracket assembly 13 to rotate from the second working position 31 to the third working position 41, the first push rod 1513 and the second push rod 1523 rotate relative to the fixed shaft 111 respectively, and driven by the first hinge shaft 1512 and the second hinge shaft 1522, the first connecting rod 1511 and the second connecting rod 1521 rotate around the third installation point 1 respectively, thereby driving the first grabbing group 141 to rotate around the first rotating shaft 1411 and the second grabbing group 142 to rotate around the second rotating shaft 1421. Therefore, in the process of the grabbing assembly 14 rotating to the corresponding working position, the substrate 5 grabbed on the grabbing assembly 14 is rotated to adjust the placement direction under the drive of the connecting rod assembly 15. This matching structure is simple, and the stability and control accuracy of the adjustment of the placement direction of the substrate 5 are high.
[0052] It can be understood that when the grabbing assembly 14 is only provided with one grabbing group 14a, the connecting rod assembly 15 also correspondingly includes only one connecting rod group 15a, that is, the corresponding number of connecting rod groups 15a is adaptively matched according to the number of grabbing groups 14a provided on a bracket assembly 13, without specific limitation.
[0053] In some embodiments, the gripping assembly 14 further includes a third gripping group 143 and a fourth gripping group 144, which are rotatably connected to the second bracket 132.

The second bracket 132 positions the third and fourth gripping groups 143, 144 above the first workstation 21 to access and place substrates 5 therein. The drive shaft 121 drives the first and second brackets 131, 132 to rotate simultaneously, allowing the third and fourth gripping groups 143, 144 to transfer substrates 5 captured at the first workstation 21 to the second workstation 31, and the first and second gripping groups 141, 142 to transfer substrates 5 captured at the second workstation 31 to the third workstation 41.

While the drive shaft 121 drives the first bracket 131 and the second bracket 132 to rotate in the horizontal plane, the third link group 153 and the fourth link group 154 can drive the third grabbing group 143 and the fourth grabbing group 144 to rotate synchronously.
