DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0028] In the process of preparing solar cells, silicon wafers usually need to go through production processes such as texturing, diffusion, laser cutting, etching, coating, printing, sintering, and testing. After laser cutting, silicon wafers will have cross sections. If the laser-cut silicon wafers are directly soldered, the conversion efficiency of the solar cells will be attenuated. Therefore, the industry adopts the passivation treatment of the cross sections of the laser-cut silicon wafers before the silicon wafers are soldered to ensure the conversion efficiency of the solar cells.

[0029] At present, the industry uses deposition equipment to coat the cross-section of silicon wafers to achieve passivation treatment. If the laser-cut silicon wafer is directly placed in the deposition equipment for coating, the non-cross-section of the silicon wafer will be exposed, and the passivation gas will diffuse to the non-cross-section of the silicon wafer, resulting in the phenomenon of wrapping plating on the non-cross-section of the silicon wafer, which will greatly affect the conversion efficiency of the battery cell. Therefore, in order to reduce the phenomenon of wrapping plating on the non-cross-section of the silicon wafer, a carrier is usually used to hold the silicon wafer to cover the non-cross-section of the silicon wafer.

[0030] However, most of the related technologies use manual methods to place silicon wafers on carriers. It is easy to produce large errors when manually placing silicon wafers, resulting in poor consistency in the placement position and placement angle of the silicon wafers in the carrier, which in turn leads to poor consistency in the process processing effects of the silicon wafers.

[0031] In addition, the manual method of taking and placing silicon wafers is slow, resulting in a long time for the silicon wafer taking and placing process, which in turn leads to a long processing time for the silicon wafers and low processing efficiency.

[0032] In view of the above problems, an embodiment of the present disclosure provides a sheet carrier, which is applied to a sheet handling system. The sheet handling system includes a sheet handling device and a lifting device. The sheet handling device is configured to place multiple sheets of sheet materials on the lifting device or take them away from the lifting device. The lifting device is configured to carry multiple sheets of sheet materials and place multiple sheets of sheet materials on the sheet carrier or send them out from the sheet carrier. The sheet carrier includes a cavity, which has a first accommodating cavity. The first accommodating cavity is configured to accommodate multiple sheets of sheet materials placed in a stacked manner. The cavity also has a first opening, which is connected to the first accommodating cavity, and the sheet material enters and exits the first accommodating cavity through the first opening. The cavity also has at least one first notch, which is connected to the first accommodating cavity. The lifting device can enter the first accommodating cavity through the first notch. The lifting device carries the sheet material and drives the sheet material to move along a first direction. The first direction intersects with the plane where the first opening is located. The cavity also has a second opening, which is communicated with the first accommodating cavity and arranged opposite to the first opening, so that the passivation gas can enter and exit the first accommodating cavity and passivate the sheet material.

[0033] The sheet carrier provided by the embodiment of the present disclosure is applied to a sheet handling system, and the sheet handling system includes a sheet handling device and a lifting device. The sheet handling device is configured to place multiple sheets of sheet materials on the lifting device or take them away from the lifting device. The lifting device is configured to carry multiple sheets of sheet materials and place multiple sheets of sheet materials on the sheet carrier or send them out from the sheet carrier. The sheet carrier has a first accommodating cavity, a first opening, at least one first notch and a second opening. The sheet material enters and exits the first accommodating cavity through the first opening, and the first notch is connected to the first accommodating cavity, so that when the lifting device carries multiple sheets of sheet materials with a good degree of consistency in placement angle and enters the first accommodating cavity from the first opening, the first notch can allow the lifting device to pass through, avoiding the obstruction of the lifting device by the cavity of the sheet carrier, so that the lifting device can smoothly place multiple sheets of sheet materials into the sheet carrier, maintain the consistency of the placement position and placement angle of the multiple sheets of sheet materials placed in the sheet carrier, and improve the consistency of the process processing effect of the multiple sheets of sheet materials placed in the sheet carrier.

[0034] In addition, using a sheet material handling device to automatically pick up and place multiple sheets of sheet materials, and using a lifting device to place multiple sheets of sheet materials on a sheet material carrier or send them out from a sheet material carrier, can speed up the picking and placing of sheet materials, and the picking and placing process takes a short time, which can shorten the processing time of sheet materials and improve the efficiency of the processing of sheet materials.

[0035] The specific structure of the sheet carrier is described below in conjunction with an embodiment.

The lifting device 20 is configured to carry multiple sheets of sheet materials 2 and place multiple sheets of sheet materials 2 on the sheet carrier 10 or send them out from the sheet carrier 10. The sheet carrier 10 includes a cavity 100, which has a first accommodating cavity 101, and the first accommodating cavity 101 is configured to accommodate multiple sheets of sheet materials 2 placed in layers. The cavity 100 also has a first opening 102, which is connected to the first accommodating cavity 101, and the sheet materials 2 enter and exit the first accommodating cavity 101 through the first opening 102. The cavity 100 also has at least one first notch 103, which is in communication with the first accommodating cavity 101. The lifting device 20 can enter the first accommodating cavity 101 through the first notch 103. The lifting device 20 moves along the first direction X1. The lifting device 20 carries the sheet material 2 and drives the sheet material 2 to move along the first direction X1 to place the sheet material 2 in the first accommodating cavity 101. The first direction X1 intersects with the plane where the first opening 102 is located. The cavity 100 also has a second opening 104, which is in communication with the first accommodating cavity 101 and is arranged opposite to the first opening 102, so that the passivation gas can enter and exit the first accommodating cavity 101 and passivate the sheet material 2.

[0037] Exemplarily, the sheet material transporting device 30 may include a robot arm, a suction cup or other components, which is not specifically limited in the present disclosure.

[0038] Exemplarily, the lifting device 20 may include a cylinder, a linear module, a robotic arm or other components, which is not specifically limited in the present disclosure.

[0039] Exemplarily, the lifting device 20 includes a first driving component 2010 and at least one push rod component 2020, the push rod component 2020 is connected to the first driving component 2010, the first driving component 2010 drives the push rod component 2020 to move along the first direction X1, the push rod component 2020 can pass through the first notch 103 to enter the first accommodating cavity 101, the push rod component 2020 carries the sheet material 2 and drives the sheet material 2 to move along the first direction X1 to place the sheet material 2 in the first accommodating cavity 101.

[0040] The sheet material 2 can be a silicon wafer, a battery panel, a glass substrate, etc.

[0041] The cross-sectional shape of the cavity 100 may be a rectangle, a parallelogram, or other polygonal or irregular shapes, which is not specifically limited in the present disclosure.

[0042] The cross-sectional shape of the second opening 104 may be a rectangle, a convex shape, or other polygonal or irregular shapes, which is not specifically limited in the present disclosure.

[0043] The sheet carrier 10 provided in the embodiment of the present disclosure is applied to a sheet transport system 1, which includes a sheet transport device 30 and a lifting device 20. The sheet transport device 30 is configured to place multiple sheets of sheet materials 2 on the lifting device 20 or take them away from the lifting device 20. The lifting device 20 is configured to carry multiple sheets of sheet materials 2 and place multiple sheets of sheet materials 2 on the sheet carrier 10 or send them out from the sheet carrier 10. The sheet carrier 10 has a first accommodating cavity 101, a first opening 102, at least one first notch 103 and a second opening 104. The stacked multiple sheets of sheet material 2 enter and exit the first accommodating chamber 101 through the first opening 102, and the first notch 103 is connected to the first accommodating chamber 101, so that when the lifting device 20 carries the stacked multiple sheets of sheet material 2 with a good consistency in placement angle into the first accommodating chamber 101 from the first opening 102, the first notch 103 can allow the lifting device 20 to pass through, thereby avoiding the cavity 100 of the sheet carrier 10 from blocking the lifting device 20, so that the lifting device 20 can smoothly place the stacked multiple sheets of sheet material 2 with a good consistency in placement angle into the sheet carrier 10, maintain the consistency of the placement position and placement angle of the stacked multiple sheets of sheet material 2 in the sheet carrier 10, and improve the consistency of the process processing effect of the stacked multiple sheets of sheet material 2.

[0044] In addition, the sheet material handling device 30 is used to automatically pick up and place multiple sheets of sheet material 2, and the lifting device 20 is used to place multiple sheets of sheet material 2 on the sheet carrier 10 or send them out from the sheet carrier 10. This can speed up the picking and placing of the sheet material 2, and the picking and placing process takes a short time, which can shorten the processing time of the sheet material 2 and improve the efficiency of the processing of the sheet material 2.

[0045] In some embodiments, the cavity 100 includes a bottom plate 110, a top plate 120, a first side plate 130, a second side plate 140, and a third side plate 150. The top plate 120 is arranged opposite to the bottom plate 110. When the first accommodating cavity 101 accommodates a plurality of stacked sheets of sheet materials 2, the plurality of sheet materials 2 are stacked along a first direction X1, and the cross section of the sheet materials 2 faces the top plate 120. There is a gap between the cross section of the sheet materials 2 and the top plate 120, and the gap forms a gas circulation space. The first side plate 130 connects the bottom plate 110 and the top plate 120, and the second side plate 140 is arranged opposite to the first side plate 130 and connects the bottom plate 110 and the top plate 120. The bottom plate 110, the top plate 120, the first side plate 130, and the second side plate 140 form a first opening 102. The third side plate 150 is disposed opposite to the first opening 102, and the third side plate 150 connects the first side plate 130 and the second side plate 140, and is connected to the bottom plate 110. The first notch 103 is disposed on the third side plate 150, and a second opening 104 is formed between the third side plate 150 and the top plate 120. The cavity 100 has a simple structure.

[0046] In some embodiments, the cavity 100 is an axisymmetric structure, and the number of the first notches 103 is multiple, and the multiple first notches 103 are arranged on the third side plate 150. When the number of the first notches 103 is two, the two first notches 103 are arranged at two opposite edge areas of the third side plate 150, and the lifting device 20 can pass through the two first notches 103 to enter the first accommodating cavity 101, and respectively carry the two sides of the sheet material 2, so as to improve the stability of the lifting device 20 in carrying the sheet material 2.

[0047] For example, Figures 2 to 4 As shown, the lifting device 20 includes two push rod assemblies 2020, and the two push rod assemblies 2020 are respectively connected to the two sides of the first driving assembly 2010. The first driving assembly 2010 drives the two push rod assemblies 2020 to move simultaneously along the first direction X1. The two push rod assemblies 2020 can respectively pass through the two first notches 103 and enter the first accommodating cavity 101. The two push rod assemblies 2020 respectively support the two sides of the sheet material 2.

[0048] Exemplarily, each push rod assembly 2020 includes two push rods 2021, and the two push rods 2021 respectively support the two edges on one side of the sheet material 2, and the other two push rods 2021 respectively support the two edges on the other side of the sheet material 2, so that the four push rods 2021 respectively support the four edges of the sheet material 2, so as to further improve the stability of the lifting device 20 in carrying the sheet material 2.

[0049] Exemplarily, the cross-sectional shape of the first notch 103 may be a rectangle, a parallelogram, or other polygonal or irregular shapes, which is not specifically limited in the present disclosure.

[0050] In some embodiments, the sheet carrier 10 further includes a first pad 200, which is disposed separately from the cavity 100, and can be placed in the first receiving cavity 101, and is configured to carry the sheet material 2. When the first pad 200 carries the sheet material 2, the first surface 201 of the first pad 200 contacts the sheet material 2, the lifting device 20 abuts against the second surface 202 of the first pad 200, and the second surface 202 is disposed opposite to the first surface 201. When the first receiving cavity 101 accommodates a plurality of stacked sheets of sheet material 2, the second surface 202 of the first pad 200 can contact the third side plate 150, wherein in the direction from the bottom plate 110 vertically pointing to the top plate 120, the size of the first pad 200 is smaller than the size of the third side plate 150, so as to prevent the first pad 200 from blocking the second opening 104. The first pad 200 is used to support the stacked multiple sheets of sheet material 2, so that the lifting device 20 can place the stacked multiple sheets of sheet material 2 in the first accommodating cavity 101. It can also prevent the lifting device 20 from directly contacting the sheet material 2, so as to prevent the lifting device 20 from applying too much force to the sheet material 2, thereby causing marks on the surface of the sheet material 2 or even breaking the sheet material 2.

[0051] Exemplarily, the passivation gas enters the first accommodation cavity 101 from the second opening 104 , passes through the gas circulation space, part of the passivation gas passivates the cross section of the sheet material 2 , and the other part of the passivation gas flows out from the first opening 102 .

[0052] Exemplarily, the passivation gas enters the first accommodating chamber 101 from the first opening 102 , passes through the gas circulation space, part of the passivation gas passivates the cross section of the sheet material 2 , and the other part of the passivation gas flows out from the second opening 104 .

[0053] The cross-sectional shape of the first pad 200 may be a rectangle, a parallelogram, or other polygonal or irregular shapes, which is not specifically limited in the present disclosure.

[0054] Exemplarily, the four push rods 2021 of the lifting device 20 respectively abut against the four edges of the first pad 200 to improve the stability of the lifting device 20 in carrying the first pad 200 , thereby improving the stability of the lifting device 20 in carrying the sheet material 2 .

[0055] In some embodiments, the third side plate 150 has a first positioning hole 1501, and the second surface 202 of the first pad 200 has a positioning portion 210, and the positioning portion 210 can penetrate the first positioning hole 1501. By using the first positioning hole 1501 and the positioning portion 210 to cooperate, the accuracy and stability of placing multiple stacked sheet materials 2 in the first accommodating cavity 101 can be improved.

[0056] The cross-sectional shape of the first positioning hole 1502 may be rectangular, circular, or other polygonal or irregular shapes, which is not specifically limited in the present disclosure.

[0057] The cross-sectional shape of the positioning portion 210 may be rectangular, circular, or other polygonal or irregular shapes, which is not specifically limited in the present disclosure. For example, the cross-sectional shape of the first positioning hole 1501 is circular, and the cross-sectional shape of the positioning portion 210 is circular.

[0058] In some embodiments, the sheet carrier 10 further includes a second pad 300, which is disposed separately from the cavity 100. The second pad 300 can be placed in the first accommodating cavity 101. When the first accommodating cavity 101 accommodates a plurality of stacked sheet materials 2, the second pad 300 is located on the side of the stacked sheet materials 2 away from the first pad 200. When the lifting device 20 places the stacked sheet materials 2 in the first accommodating cavity 101, the second pad 300 is used to shield the surface of the sheet material 2 away from the first pad 200 to reduce the plating phenomenon on the surface of the sheet material 2 away from the first pad 200. In the direction from the bottom plate 110 vertically to the top plate 120, the size of the second pad 300 is smaller than the size of the first opening 102 to avoid the second pad 300 completely shielding the first opening 102.

[0059] The cross-sectional shape of the second pad 300 may be a rectangle, a parallelogram, or other polygonal or irregular shapes, which is not specifically limited in the present disclosure.

[0060] In some embodiments, when the first accommodating cavity 101 accommodates multiple sheets of sheet materials 2 stacked in layers, the difference between the vertical distance between the first side plate 130 and the second side plate 140 and the length of the sheet material 2 in the second direction X2 is less than 3 mm and greater than 0.1 mm, wherein the second direction X2 is the direction from the first side plate 130 vertically pointing to the second side plate 140. By reasonably setting the size of the first accommodating cavity 101, the first accommodating cavity 101 can shield the non-section of the sheet material 2, and at the same time, it is convenient for the sheet material 2 to be placed in the first accommodating cavity 101 or sent out from the first accommodating cavity 101.

[0061] In some embodiments, the sheet carrier 10 further includes at least one handle 400, which is disposed on a side of the top plate 120 away from the first accommodating cavity 101. When the sheet carrier 10 includes one handle 400, the handle 400 is disposed in the middle of the top plate 120. When the sheet carrier 10 includes multiple handles 400, the multiple handles 400 are disposed at two opposite edge regions of the top plate 120. By reasonably setting the position of the handle 400, the stability of the sheet carrier 10 during the pick-up and placement process is improved.

[0062] For example, Figure 3 and Figure 4 As shown, the sheet carrier 10 includes two handles 400 . The two handles 400 are disposed at two opposite edge regions of the top plate 120 , and the two handles 400 extend along the first direction X1 .

[0063] like Figure 1 As shown, the sheet material handling system 1 provided by the embodiment of the present disclosure includes: the sheet material carrier 10, the lifting device 20, the sheet material handling device 30, the sheet material carrier handling device 40 and the boat 50 mentioned in the above embodiment, the sheet material carrier 10 is configured to contain multiple sheets of sheet materials 2 placed in layers. The lifting device 20 can enter the first accommodating chamber 101 through the first notch 103, and the lifting device 20 is configured to carry multiple sheets of sheet materials 2, and place multiple sheets of sheet materials 2 on the sheet material carrier 10 or send them out from the sheet material carrier 10. The sheet material handling device 30 is configured to place the sheet material 2 on the lifting device 20 or take it away from the lifting device 20. The sheet material carrier handling device 40 is configured to press the multiple sheets of sheet materials 2 placed in layers contained in the sheet material carrier 10, and transport the sheet material carrier 10. The boat 50 has at least one second accommodating chamber 501, and the second accommodating chamber 501 is configured to accommodate at least one sheet material carrier 10. The boat 50 further has a third opening 502 , which is in communication with the second accommodating chamber 501 . The passivating gas enters the second accommodating chamber 501 through the third opening 502 . The third opening 502 is disposed adjacent to or opposite to the second opening 104 of the sheet carrier 10 .

[0064] For example, Figure 1 and Figure 2 As shown, the lifting device 20 also has a first positioning component 2030, the first driving component 2010 is connected to the first positioning component 2030, and the sheet carrier 10 is placed on the first positioning component 2030. The first positioning component 2030 is configured to position the placement position and placement angle of the sheet carrier 10 to ensure that the sheet transport device 30 can accurately place the sheet material 2 on the lifting device 20, and the lifting device 20 can accurately place the sheet material 2 on the sheet carrier 10.

[0065] For example, Figure 1 , Figure 5and Figure 6 As shown, the sheet carrier transport device 40 includes a first transport device 410 and a second transport device 420. The first transport device 410 is configured to transport the sheet carrier 10 so that the sheet carrier 10 is transported to the first position by the lifting device 20. The second transport device 420 is configured to press the stacked multiple sheets of sheet material 2 contained in the sheet carrier 10 and transport the sheet carrier 10 so that the sheet carrier 10 is transported from the first position to the boat 50.

[0066] Exemplarily, the first handling device 410 may include a robotic arm, a linear module, or other structures, which are not specifically limited in the present disclosure.

[0067] Exemplarily, the second handling device 420 may include a robotic arm, a linear module, or other structures, which are not specifically limited in the present disclosure.

[0068] For example, Figure 4 and Figure 5 As shown, the first transport device 410 includes a second drive assembly 4110 and at least one second positioning assembly 4120. The cavity 100 of the sheet carrier 10 also has at least one second positioning hole 106. The second positioning assembly 4120 is connected to the second drive assembly 4110, and the second drive assembly 4110 drives the second positioning assembly 4120 to move so that the second positioning assembly 4120 penetrates the second positioning hole 106, thereby realizing the first transport device 410 to grasp the sheet carrier 10. The second drive assembly 4110 drives the second positioning assembly 4120 to move, and the first positioning assembly 4120 drives the sheet carrier 10 to move, so as to transport the sheet carrier 10 from the first positioning assembly 2030 of the lifting device 20 to the first position.

[0069] Exemplarily, the number of the second positioning holes 106 is four, two second positioning holes 106 are arranged at two opposite edge regions of the first side plate 130, and the other two second positioning holes 106 are arranged at two opposite edge regions of the second side plate 140, and the second positioning holes 106 on the second side plate 140 are arranged opposite to the second positioning holes 106 on the first side plate 130. The number of the second positioning components 4120 is four, two second positioning components 4120 are respectively inserted into the two second positioning holes 106 on the first side plate 130, and the other two second positioning components 4120 are respectively inserted into the two second positioning holes 106 on the second side plate 140, so as to enable the first handling device 410 to grasp the sheet carrier 10, and this grasping method is stable and reliable.

[0070] For example, Figure 6As shown, the second transport device 420 includes a third driving assembly, at least one third positioning assembly 4220, at least one clamping assembly 4230 and at least one clamping assembly 4240. The third driving assembly is respectively connected to the third positioning assembly 4220, the clamping assembly 4230 and the clamping assembly 4240. The third driving assembly simultaneously drives the third positioning assembly 4220, the clamping assembly 4230 and the clamping assembly 4240 to move to the sheet carrier 10 close to the first position.

[0071] For example, Figure 3 and Figure 6 As shown, the handle 400 has at least one third positioning hole 401, and the third positioning assembly 4220 moves so that the third positioning assembly 4220 is inserted into the third positioning hole 401, so that the second handling device 420 can grasp and position the sheet carrier 10. The pressing assembly 4230 moves so that the pressing assembly 4230 abuts against the side of the second pad 300 away from the sheet material 2, and applies force to the second pad 300 to compress the stacked multiple sheets of sheet material 2. The side of the top plate 120 away from the first accommodating cavity 101 has at least one avoidance groove 1201, and the clamping claw assembly 4240 penetrates into the avoidance groove 1201, and grasps the handle 400 by the side of the handle 400 close to the top plate 120, so that the second handling device 420 can grasp the sheet carrier 10. The third driving assembly drives the third positioning assembly 4220 , the pressing assembly 4230 and the clamping assembly 4240 to move simultaneously, so that the second transporting device 420 transports the sheet carrier 10 from the first position to the boat 50 .

[0072] Exemplarily, there are two third positioning assemblies 4220 and two clamping jaw assemblies 4240, and two avoidance grooves 1201. During the process of the second conveying device 420 conveying the sheet carrier 10, the clamping assembly 4230 presses the stacked multiple sheets of sheet materials 2 to avoid displacement or even falling of the stacked multiple sheets of sheet materials 2 due to vibration, so that the placement position and placement angle of the sheet material 2 in the sheet carrier 10 remain unchanged during the conveying process of the sheet carrier 10, so as to improve the consistency of the placement position and placement angle of the stacked multiple sheets of sheet materials 2 in the boat 50.

[0073] For example, Figure 7 As shown, when the sheet carrier 10 is placed in the second receiving cavity 501 , the top plate 120 of the sheet carrier 10 is located above the boat 50 , and there is a gap between the top plate 120 and the boat 50 , and the gap forms the third opening 502 .

[0074] In some embodiments, the sheet material handling system 1 further includes at least one sensor 60 , which is disposed on the lifting device 20 , and the sensor 60 is configured to detect the placement positions of the multiple stacked sheet materials 2 contained in the sheet material carrier 10 .

[0075] In some embodiments, the sheet material handling system 1 further includes at least one sensor 60 , which is disposed on the sheet material carrier 10 , and the sensor 60 is configured to detect the placement position of the stacked sheet materials 2 contained in the sheet material carrier 10 .

[0076] Exemplarily, the cavity 100 of the sheet carrier 10 further has at least one third notch 107, and the third notch 107 is configured to install the sensor 60. Exemplarily, as Figure 1 and Figure 3 As shown, the cavity 100 of the sheet carrier 10 has two third notches 107 , and a sensor 60 is installed at each third notch 107 .

[0077] The sensor 60 may be a micro switch, a through-beam photoelectric sensor, or other types of sensors, which are not specifically limited in the present disclosure.

[0078] In some embodiments, the sheet material handling system 1 further includes at least one limiting device 70. The sheet material carrier 10 further has at least two second notches 105, and the limiting device 70 can pass through the second notches 105 and enter the sheet material carrier 10. In the case where the sheet material carrier 10 contains a plurality of stacked sheet materials 2, the limiting device 70 is configured to limit the position of the sheet material 2 in the sheet material carrier 10. The limiting device 70 is used to limit the position of the sheet material 2 in the sheet material carrier 10 so that the sheet material 2 is placed in the center of the sheet material carrier 10 to avoid the edge of the sheet material 2 from contacting the sheet material carrier 10, thereby avoiding the generation of friction between the sheet material 2 and the sheet carrier 10 when the sheet material 2 is sent out of the sheet carrier 10 by the lifting device 20, and the friction hinders the lifting device 20 from sending the sheet material 2 out of the sheet carrier 10, or causes the edge of the sheet material 2 to be worn, thereby damaging the sheet material 2.

[0079] Exemplarily, the limiting device 70 includes a cylinder assembly, a mechanical arm or other structures, which are not specifically limited in the present disclosure.

[0080] For example, Figure 4 and Figure 8As shown, the sheet carrier 10 also has two second notches 105, one second notch 105 is provided on the first side plate 130, and the other second notch 105 is provided on the second side plate 140, and the two second notches 105 are arranged opposite to each other, and the second notches 105 are communicated with the first accommodating cavity 101. A limiting device 70 is provided corresponding to a second notch 105, and the two limiting devices 70 can respectively pass through the second notch 105 and enter the first accommodating cavity 101.

[0081] Exemplarily, the two limiting devices 70 respectively abut against the two edges of the first pad 200 to adjust the placement angle of the first pad 200 in the sheet carrier 10, so that the limiting devices 70 adjust the placement position and placement angle of the multiple stacked sheet materials 2 carried by the first pad 200 in the sheet carrier 10, so that the sheet material 2 is placed centrally in the sheet carrier 10, thereby avoiding contact between the sheet material 2 and the inner wall of the sheet carrier 10, and further avoiding friction between the sheet material 2 and the sheet carrier 10, so that the sheet material 2 can be smoothly sent out of the first accommodating cavity 101 by the lifting device 20, and the sheet material 2 will not be damaged.

[0082] Since the sheet material transporting system 1 includes the sheet material carrier 10 , the sheet material transporting system 1 includes all the technical features and technical effects of the sheet material carrier 10 , which will not be described in detail herein.
