Technical Field

[0001] The present disclosure relates to the photovoltaic field, and in particular to a sheet carrier and a sheet transport system. Background Art

[0002] At present, the industry uses deposition equipment to coat laser-cut silicon wafers to achieve passivation treatment. If the laser-cut silicon wafer is directly placed in the deposition equipment for coating, the non-section of the silicon wafer will be exposed, and the passivation gas will diffuse to the non-section of the silicon wafer, resulting in the phenomenon of wrapping plating on the non-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-section of the silicon wafer, a carrier is usually used to hold the silicon wafer to cover the non-section of the silicon wafer.

DETAILED DESCRIPTION

[0028] 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.

[0029] 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.

[0030] 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.

[0031] However, most of the related technologies use manual methods to place silicon wafers in or take them out of carriers. Due to the poor stability of manually placed silicon wafers, the placement position and placement angle of the silicon wafers in the carrier are inconsistent, which in turn leads to poor consistency in the process processing effects of the silicon wafers.

[0032] 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.

[0033] In view of the above problems, an embodiment of the present disclosure provides a sheet carrier, which is applied to a sheet handling device, and the sheet handling device is configured to place multiple sheets of stacked sheet materials on the sheet carrier or take away multiple sheets of stacked sheet materials from the sheet carrier. The sheet carrier includes a cavity, which has a first accommodating cavity, and the first accommodating cavity is configured to accommodate multiple sheets of stacked sheet materials. The cavity also has a first opening, which is connected to the first accommodating cavity, and the multiple sheets of stacked sheet materials enter and exit the first accommodating cavity through the first opening. The cavity also has at least one first avoidance gap, each of which is connected to the first accommodating cavity and the first opening, respectively, and the first avoidance gap is configured to avoid the sheet handling device, wherein the first avoidance gap extends along a first direction, and the first direction intersects with the plane where the first opening is located. The cavity also has a second opening, which is connected to the first accommodating cavity and is arranged opposite to the first opening, so that the passivation gas can enter and exit the first accommodating cavity and passivate the sheet material.

[0034] The sheet carrier provided by the embodiment of the present disclosure is applied to a sheet handling device, and the sheet carrier has a first accommodating cavity, a first opening, at least one first avoidance notch, and a second opening. Multiple sheets of stacked sheet materials enter and exit the first accommodating cavity through the first opening, and the first avoidance notch is respectively connected to the first accommodating cavity and the first opening, so that when the sheet handling device enters the first accommodating cavity from the first opening while clamping multiple sheets of stacked sheet materials with a relatively good degree of consistency in placement angles, the first avoidance notch can allow the sheet handling device to pass through, thereby avoiding the obstruction of the sheet handling device by the cavity of the sheet carrier, so that the sheet handling device can smoothly place multiple sheets of stacked sheet materials with a relatively good degree of consistency in placement angles into the sheet carrier, maintain the consistency of the placement position and placement angle of the multiple sheets of stacked sheet materials in the sheet carrier, and improve the consistency of the process processing effect of the multiple sheets of stacked sheet materials.

[0035] In addition, using a sheet material handling device to automatically pick up and place multiple stacked sheets of sheet materials can speed up the picking and placing of sheet materials, shorten the picking and placing process, shorten the processing time of sheet materials, and improve the processing efficiency of sheet materials.

[0036] The specific structure of the sheet carrier is described below in conjunction with an embodiment.

[0037] Figure 1 Shown is a schematic structural diagram of a sheet carrier and a sheet transporting device provided in one embodiment of the present disclosure. Figure 2 FIG. 1 is a schematic diagram of the structure of a sheet carrier provided by an embodiment of the present disclosure. Figure 1 to Figure 2 As shown, the sheet carrier 10 is applied to a sheet conveying device 20 , and the sheet conveying device 20 is configured to place a plurality of stacked sheet materials 2 on the sheet carrier 10 or remove a plurality of stacked sheet materials 2 from the sheet carrier 10 .

[0038] 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 a stacked manner. The cavity 100 also has a first opening 102, which is in communication with the first accommodating cavity 101, and the multiple sheets of sheet materials 2 placed in a stacked manner enter and exit the first accommodating cavity 101 through the first opening 102. The cavity 100 also has at least one first avoidance gap 103, each of which is in communication with the first accommodating cavity 101 and the first opening 102, and the first avoidance gap 103 is configured to avoid the sheet transport device 20, wherein the first avoidance gap 103 extends along a first direction X1, and the first direction X1 intersects with the plane where the first opening 102 is located. The cavity 100 further has a second opening 104 , which is communicated with the first accommodating cavity 101 and 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 .

[0039] Exemplarily, the sheet material transporting device 20 may include a robotic arm or other components, which is not specifically limited in the present disclosure.

[0040] For example, Figure 1 As shown, the sheet material transporting device 20 comprises a supporting assembly 2010, a first driving assembly 2020, a transporting assembly 2030 and a first pressing assembly 2040. The first driving assembly 2020 is connected to the supporting assembly 2010 and the transporting assembly 2030 respectively, the first pressing assembly 2040 is connected to the transporting assembly 2030, and the first driving assembly 2020 is configured to provide a driving force to drive the transporting assembly 2030 and the pressing assembly 20 to move, so that the pressing assembly 20 presses the stacked multiple sheets of sheet materials 2, and the transporting assembly 2030 grabs the stacked multiple sheets of sheet materials 2, and places the stacked multiple sheets of sheet materials 2 on the sheet carrier 10, or takes the stacked multiple sheets of sheet materials 2 away from the sheet carrier 10. By using the clamping assembly 20 to compress the stacked multiple sheets of sheet material 2, it is possible to prevent the stacked multiple sheets of sheet material 2 from shifting or even falling due to vibration during the process of the sheet material conveying device 20 conveying the stacked multiple sheets of sheet material 2. As a result, the state of the stacked multiple sheets of sheet material 2 remains unchanged during the conveying process, thereby improving the consistency of the placement position and placement angle of the stacked multiple sheets of sheet material 2 in the first accommodating cavity 101.

[0041] Exemplarily, the handling assembly 2030 includes at least one first clamping structure 2031, and the first clamping structure 2031 is configured to grasp the stacked multiple sheet materials 2. When the sheet handling device 20 places the stacked multiple sheet materials 2 on the sheet carrier 10 or removes the stacked multiple sheet materials 2 from the sheet carrier 10, the first avoidance gap 103 avoids the first clamping structure 2031.

[0042] The sheet material 2 can be a silicon wafer, a battery panel, a glass substrate, etc.

[0043] 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.

[0044] 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.

[0045] The sheet carrier 10 provided in the embodiment of the present disclosure is applied to a sheet transporting device 20 . The sheet carrier 10 has a first accommodating cavity 101 , a first opening 102 , at least one first avoidance notch 103 and a second opening 104 . The stacked multiple sheets of sheet materials 2 enter and exit the first accommodating chamber 101 through the first opening 102, and the first avoidance gap 103 is connected to the first accommodating chamber 101 and the first opening 102 respectively, so that when the sheet material handling device 20 enters the first accommodating chamber 101 from the first opening 102 with the stacked multiple sheets of sheet materials 2 having a relatively good consistency in placement angle, the first avoidance gap 103 can allow the sheet material handling device 20 to pass through, thereby avoiding obstruction of the sheet material handling device 20 by the cavity 100 of the sheet carrier 10, so that the sheet material handling device 20 can smoothly place the stacked multiple sheets of sheet materials 2 having a relatively good consistency in placement angle into the sheet carrier 10, thereby maintaining the consistency of the placement position and placement angle of the stacked multiple sheets of sheet materials 2 in the sheet carrier 10, and improving the consistency of the process processing effects of the stacked multiple sheets of sheet materials 2.

[0046] In addition, the sheet material handling device 20 is used to automatically pick up and place multiple stacked sheets of sheet materials 2. The picking and placing speed of the sheet materials 2 is fast and the picking and placing process takes a short time, which can shorten the processing time of the sheet materials 2 and improve the processing efficiency of the sheet materials 2.

[0047] 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 21 of the sheet materials faces the top plate 120. There is a gap between the cross section 21 of the sheet materials and the top plate 120, and the gap forms a gas circulation space 1010. 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. Exemplarily, the cavity 100 has a first avoidance notch 103, and the first avoidance notch 103 is located on the first side plate 130, or the first avoidance notch 103 is located on the second side plate 140. Exemplarily, the cavity 100 has two first avoidance notches 103, and the two first avoidance notches 103 are respectively located on the first side plate 130 and the second side plate 140. The third side plate 150 is arranged 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, and the second opening 104 is formed between the third side plate 150 and the top plate 120. The cavity 100 has a simple structure.

[0048] Exemplarily, the passivation gas enters the first accommodation chamber 101 from the second opening 104 , passes through the gas circulation space 1010 , part of the passivation gas passivates the cross section 21 of the sheet material, and the other part of the passivation gas flows out from the first opening 102 .

[0049] Exemplarily, the passivation gas enters the first accommodation chamber 101 from the first opening 102 , passes through the gas circulation space 1010 , part of the passivation gas passivates the cross section 21 of the sheet material, and the other part of the passivation gas flows out from the second opening 104 .

[0050] In some embodiments, the cavity 100 is an axisymmetric structure, and the edge of the third side plate 150 has a second avoidance gap 1501, and the second avoidance gap 1501 is connected to the first avoidance gap 103. The first side plate 130 includes a first baffle 1310 and a second baffle 1320, the first baffle 1310 is connected to the top plate 120, and the second baffle 1320 is connected to the bottom plate 110, and the first baffle 1310 and the second baffle 1320 form a first avoidance gap 103. When the sheet material handling device 20 places the stacked multiple sheet materials 2 in the first accommodating cavity 101, the sheet material handling device 20 moves along the first direction X1 and penetrates the first avoidance gap 103 and the second avoidance gap 1501. The first avoidance gap 103 has a simple structure.

[0051] In some embodiments, the second side plate 140 includes a third baffle 1410 and a fourth baffle 1420, the third baffle 1410 is connected to the top plate 120, the fourth baffle 1420 is connected to the bottom plate 110, and the third baffle 1410 and the fourth baffle 1420 form a first avoidance gap 103. When the sheet material transporting device 20 places the stacked multiple sheet materials 2 in the first accommodating cavity 101, the sheet material transporting device 20 moves along the first direction X1 and penetrates the first avoidance gap 103 and the second avoidance gap 1501. The first avoidance gap 103 has a simple structure.

[0052] In some embodiments, Figures 1 to 3 As shown, there are two second avoidance gaps 1501, one second avoidance gap 1501 is set at the edge of the third side plate 150 connected to the first side plate 130 to communicate with the first avoidance gap 103 on the first side plate 130, and the other second avoidance gap 1501 is set at the edge of the third side plate 150 connected to the second side plate 140 to communicate with the first avoidance gap 103 on the second side plate 140. When the sheet material conveying device 20 places the stacked multiple sheet materials 2 in the first accommodating chamber 101, the sheet material conveying device 20 grabs the two edges of the stacked multiple sheet materials 2, and the sheet material conveying device 20 moves along the first direction X1 and penetrates the first avoidance gap 103 and the second avoidance gap 1501. The sheet material conveying device 20 conveys the stacked multiple sheet materials 2 stably and reliably.

[0053] 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. When the first receiving cavity accommodates a plurality of stacked sheets of sheet material 2, the first surface 201 of the first pad contacts the sheet material 2, the second surface 202 of the first pad contacts the third side plate 150, and the second surface 202 of the first pad is disposed opposite to the first surface 201 of the first pad, wherein in the direction perpendicularly pointing from the bottom plate 110 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. When the sheet transporting device 20 places the stacked sheets of sheet material 3 in the first receiving cavity 101, the sheet transporting device 20 abuts against the second surface 202 of the first pad. The first pad 200 is used to support multiple stacked sheets of sheet materials 2, which makes it easier for the sheet material handling device 20 to place the multiple stacked sheets of sheet materials 2 into the first accommodating cavity 101 at the same time. It can also prevent the sheet material handling device 20 from directly contacting the sheet material 2, so as to prevent the sheet material handling device 20 from applying excessive force to the sheet material 2, thereby causing marks on the surface of the sheet material 2 or even breaking the sheet material 2.

[0054] For example, Figure 4 and Figure 5 As shown, the first clamping claw structure 2031 of the sheet material transporting device 20 abuts against the second surface 202 of the first pad.

[0055] 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.

[0056] In some embodiments, Figure 3 and Figure 6 As shown, the second surface 202 of the first pad has a positioning portion 210, and the third side plate 150 has a first positioning hole 1502, and the positioning portion 210 can be inserted into the first positioning hole 1502. The first positioning hole 1502 cooperates with the positioning portion 210 to improve the accuracy and stability of placing multiple stacked sheet materials 2 in the first accommodating cavity 101.

[0057] 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.

[0058] 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 1502 is circular, and the cross-sectional shape of the positioning portion 210 is circular.

[0059] In some embodiments, the sheet carrier 10 further includes a second pad 300, which is disposed separately from the cavity 100 and can be placed in the first accommodating cavity 101. When the first accommodating cavity 101 accommodates the stacked multiple sheets of sheet materials 2, the second pad 300 is located on the side of the stacked multiple sheets of sheet materials 2 away from the first pad 200. When the sheet transporting device 20 places the stacked multiple sheets of sheet materials 2 in the first accommodating cavity 101, the sheet transporting device 20 abuts against the side of the second pad 300 away from the sheet materials 2 and applies force to the second pad 300 to compress the stacked multiple sheets of sheet materials 2. 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 addition, the sheet material handling device 20 can be prevented from directly contacting the sheet material 2, so as to prevent the sheet material handling 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. In the direction from the bottom plate 110 vertically pointing to the top plate 120, the size of the second pad 300 is smaller than the size of the first opening 102, so as to prevent the second pad 300 from completely covering the first opening 102.

[0060] For example, Figure 4 and Figure 5 As shown, in the process of the sheet material handling device 20 placing multiple stacked sheets of sheet material 2 in the first accommodating cavity 101, the first clamping assembly 2040 of the sheet material handling device 20 abuts against the side of the second pad 300 away from the sheet material 2, and the side of the second pad 300 away from the sheet material 2 is the first surface 301 of the second pad.

[0061] 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.

[0062] 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 size 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 22 of the sheet material, and at the same time, it is convenient to take and put the sheet material 2.

[0063] 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 receiving cavity 101. The handle 400 is provided to facilitate taking and placing the sheet carrier 10.

[0064] 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 properly arranging the positions of the handles 400, the stability of the sheet carrier 10 during the process of taking and placing is improved.

[0065] For example, Figure 2 and Figure 3 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 .

[0066] Figure 7 FIG. 1 is a schematic diagram of the structure of a sheet material handling system provided by an embodiment of the present disclosure. Figure 7As shown, the sheet material handling system 1 includes a sheet material carrier 10, a sheet material handling device 20, a sheet material carrier handling device 30, and a boat 40. The sheet material carrier 10 is configured to contain multiple sheets of sheet materials 2 placed in layers, and the sheet material handling device 20 is configured to place multiple sheets of sheet materials 2 placed in layers on the sheet material carrier 10 or take multiple sheets of sheet materials 2 placed in layers away from the sheet material carrier 10. The sheet material carrier handling device 30 is configured to press the multiple sheets of sheet materials 2 placed in layers contained in the sheet material carrier 10 and to transport the sheet material carrier 10. The boat 40 has at least one second accommodating cavity 4001, and the second accommodating cavity 4001 is configured to accommodate at least one sheet material carrier 10. The boat 40 further has a third opening 4002 , which is in communication with the second accommodating chamber 4001 . The passivating gas enters the second accommodating chamber 4001 through the third opening 4002 . The third opening 4002 is disposed adjacent to or opposite to the second opening 104 of the sheet carrier 10 .

[0067] For example, Figure 8 As shown, the sheet carrier handling device 30 includes a second drive assembly, and at least one positioning assembly 3020, at least one second clamping structure 3030, and at least one second pressing assembly 3040 respectively connected to the second drive assembly. The second drive assembly simultaneously drives the positioning assembly 3020, the second clamping structure 3030, and the second pressing assembly 3040 to move close to the sheet carrier 10.

[0068] Exemplarily, the side of the top plate 120 away from the first accommodating cavity 101 has at least one avoidance groove 1201, the handle 400 has at least one second positioning hole 401, the positioning assembly 3020 is inserted into the second positioning hole 401 to realize the gripping and positioning of the sheet carrier 10 by the sheet carrier handling device 30, the second clamping claw structure 3030 penetrates into the avoidance groove 1201, and the handle 400 is gripped by the side of the handle 400 close to the top plate 120, the second clamping assembly 3040 abuts against the first surface 301 of the second pad, and applies force to the second pad 300 to compress the multiple sheets of sheet materials 2 stacked. The second driving assembly drives the positioning assembly 3020, the second clamping claw structure 3030 and the second clamping assembly 3040 to move to transport the sheet carrier 10 to the boat 40. Exemplarily, as Figure 2 , Figure 8 and Fig. 9As shown, there are two positioning components 3020 and two second clamping claw structures 3030. When the sheet carrier transporting device 30 transports the sheet carrier 10 to the boat 40, the second pressing component 3040 presses the stacked multiple sheets of sheet material 2 to prevent the stacked multiple sheets of sheet material 2 from shifting or even falling due to vibration, so that the state of the sheet material 2 remains unchanged during the transport 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 material 2 in the boat 40.

[0069] For example, Fig.10 As shown, when the sheet carrier 10 is placed in the second accommodating cavity 4001 , the top plate 120 of the sheet carrier 10 is located above the boat 40 , and there is a gap between the top plate 120 and the boat 40 , and the gap forms the third opening 4002 .

[0070] 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.
