DETAILED DESCRIPTION
[0027] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0028] Figure 1 The diagram shown is a structural schematic of a sheet carrier and sheet material provided in an embodiment of this disclosure. Figure 2 The image shown is a front view of a sheet carrier and sheet material provided in an embodiment of this disclosure. Figure 3 The image shown is a rear view of a sheet carrier and sheet material provided in an embodiment of this disclosure. Figure 4 The diagram shown is a structural schematic of a sheet carrier provided in one embodiment of this disclosure. Figures 1 to 4 As shown, the sheet carrier 10 is used in the passivation process of the sheet material 2, which includes a first cross-section 21 and a second cross-section 22 parallel to and opposite to the thickness direction of the sheet material 2. The sheet carrier 10 includes a cavity 100 and a support member 200. The cavity 100 has an interconnected receiving space 1001 and an opening. The receiving space 1001 is used to receive the sheet material 2. The cavity 100 is detachable or has an inlet / outlet channel 101 for the sheet material 2 to enter and exit the receiving space 1001. The opening is used for the passivation gas to flow into or out of the receiving space 1001, or for the passivation gas to flow into and out of the receiving space 1001. The support member 200 is disposed at the bottom of the receiving space 1001 for supporting the sheet material 2 located within the receiving space 1001. When the accommodating space 1001 accommodates the sheet material 2, the top of the accommodating space 1001 can approach the first section 21 and form a first gap 1011, and the bottom of the accommodating space 1001 can approach the second section 22 through the isolation of the support member 200 and form a second gap 1021. Both the first gap 1011 and the second gap 1021 are used for the passage of passivation gas.
[0029] The sheet carrier 10 provided by the embodiments of the present disclosure comprises a cavity 100 and a support 200. The cavity 100 has a containing space 1001 and an opening which are in communication with each other, and the containing space 1001 is used for containing a sheet material 2. The cavity 100 is detachable or has an access passage 101 for the sheet material 2 to access the containing space 1001. The support 200 is arranged at the bottom of the containing space 1001 of the cavity 100 and is capable of supporting the sheet material 2. The sheet material 2 has a first section 21 and a second section 22 which are arranged oppositely. In the case that the support 200 supports the sheet material 2, a first gap 1011 is formed between the first section 21 and the top of the containing space 1001, and a second gap 1021 is formed between the second section 22 and the bottom of the containing space 1001. A passivation gas can flow into the containing space 1001 through the opening, flow through the first gap 1011 and the second gap 1021, and passivate the first section 21 and the second section 22 of the sheet material 2.
[0030] Exemplarily, the support 200 is in a long rod shape, and the support 200 extends into the containing space 1001 from the access passage 101, so that the support 200 can support a plurality of sheet materials 2 which are stacked and placed.
[0031] Exemplarily, the sheet material 2 can be a silicon wafer, a battery plate, a glass substrate, etc.
[0032] Exemplarily, the cross-sectional shape of the cavity 100 can be a rectangle, a parallelogram, or other polygons or irregular shapes. Exemplarily, the cross-sectional shape of the access passage 101 can be a rectangle, a trapezoid, or other polygons or irregular shapes. Exemplarily, the cross-sectional shape of the first opening 103 can be a rectangle, a trapezoid, or other polygons or irregular shapes.
[0033] In some embodiments, the support 200 is in point contact or line contact with the second section 22.
[0034] The contact mode of point contact or line contact can reduce the contact area of the support 200 with the second section 22 as much as possible, so as to reduce the shielding of the support 200 to the second section 22 as much as possible, so that the second section 22 can be exposed as much as possible, thereby ensuring the passivation quality of the second section 22.
[0035] In some embodiments, the top of the support 200 has an arc surface 201 which is curved towards the bottom of the containing space 1001.
[0036] The support 200 is in line contact with the second section 22 through the arc surface 201, so as to reduce the shielding of the support 200 to the second section 22 as much as possible, while ensuring that the support 200 can stably support the sheet material 2.
[0037] In some embodiments, the number of the supports 200 is two, and the two supports 200 are respectively located at two sides of the bottom of the accommodating space 1001, so that the two supports 200 can respectively support two ends of the second section 21, and the stability of the placement state of the sheet material 2 is further improved.
[0038] In some embodiments, when the cavity 100 is detachable, the top of the cavity 100 is detachable, so that when the top of the cavity 100 is in a detached state, the sheet material 2 can enter and exit the accommodating space 1001.
[0039] In some embodiments, as shown in Figures 2 to 4 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 bottom plate 110 is connected with the support 200 and is configured to support the support 200. When the sheet material 2 is accommodated in the accommodating space 1001, the second section 22 faces the bottom plate 110 and has a second gap 1021 with the bottom plate 110. The top plate 120 is arranged opposite to the bottom plate 110, and when the sheet material 2 is accommodated in the accommodating space 1001, the first section 21 faces the top plate 120 and has a first gap 1011 with the top plate 120, and the first gap 1011 and the second gap 1021 form a gas flow space. The first side plate 130 connects the bottom plate 110 and the top plate 120. 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 an access channel 101. The third side plate 150 is arranged opposite to the access channel 101, connects the first side plate 130 and the second side plate 140, and is connected with the bottom plate 110. The bottom of the third side plate 150 has a first opening 103. The first opening 103 is close to the bottom of the accommodating space 1001 and communicates with the second gap 1021, and the passivation gas can flow into the second gap 1021 through the first opening 103 and flow out through the access channel 101.
[0040] The structure of the cavity 100 is simple. In addition, the above-mentioned way of introducing the passivation gas into the second gap 1021 through the first opening 103 is simple, reliable, and facilitates the circulation of the passivation gas in the second gap 1021, which can not only ensure that there is enough passivation gas in the second gap 1021, but also facilitate the flow of excess passivation gas out of the access channel 101.
[0041] Exemplarily, the connection between the mutually connected plates adopts a detachable connection mode, so as to facilitate the replacement and maintenance of each plate.
[0042] In some embodiments, as shown in Figure 3As shown, the third side plate 150 and the top plate 120 form a second opening 102, which is close to the top of the accommodating space 1001 and communicates with the first gap 1011. The passivation gas can flow into the first gap 1011 through the second opening 102 and flow out through the access passage 101.
[0043] The above-mentioned way of passing the passivation gas into the first gap 1011 through the second opening 102 is simple, reliable, and facilitates the circulation of the passivation gas in the first gap 1011, which can ensure that there is sufficient passivation gas in the first gap 1011 and facilitate the flow of excess passivation gas out of the access passage 101.
[0044] In some embodiments, the top plate 120 has a plurality of gas inlet holes 1201, which communicate the accommodating space 1001 and the outside of the cavity 100. The passivation gas can flow into the first gap 1011 through the gas inlet holes 1201 and flow out through the access passage 101.
[0045] For example, as shown in Figure 5 The plurality of gas inlet holes 1201 are uniformly arranged to further improve the uniformity of gas intake.
[0046] In the case where the top plate 120 has a plurality of gas inlet holes 1201, the third side plate 150 is sealingly connected to the top plate 120, which can control the amount of passivation gas flowing into the first gap 1011 and save energy.
[0047] For example, the cross-sectional shape of the second opening 102 can be rectangular, trapezoidal, or other polygonal or irregular shape.
[0048] In some embodiments, as shown in Figure 6 and Figure 8 The sheet material carrier 10 further includes a first backing plate 300. The first backing plate 300 is separately provided from the cavity 100 and can be placed in the accommodating space 1001. The support 200 is further configured to support the first backing plate 300. In the case where the first backing plate 300 and the sheet material 2 are located in the accommodating space 1001, the first surface 301 of the first backing plate is in contact with the third side plate 150, the second surface 302 of the first backing plate is in contact with the surface of the sheet material 2, and the first surface 301 of the first backing plate is oppositely arranged to the second surface 302 of the first backing plate.
[0049] The first backing plate 300 is used to shield the surface of the sheet material 2 to reduce the phenomenon of around-plating of the surface of the sheet material 2.
[0050] For example, the second surface 302 of the first backing plate is in contact with the first surface 2001 of the sheet material.
[0051] In addition, when the first pad plate 300 and the sheet material 2 are simultaneously taken out of the accommodating space 1001, the sheet taking and placing assembly 20 is in contact with the first surface 301 of the first pad plate, so as to avoid the sheet taking and placing assembly 20 directly contacting the first surface 2001 of the sheet material 2, thereby avoiding the first surface 2001 of the sheet material 2 being marked or even the sheet material 2 being broken due to the sheet taking and placing assembly 20 applying too large force to the sheet material 2.
[0052] In some embodiments, as shown in Figs. 1 and 2, the sheet material carrier 10 further comprises a first pad plate 300. The first pad plate 300 is separate from the cavity 100 and is capable of being placed in the accommodating space 1001. The support 200 is further configured to support the first pad plate 300. When the accommodating space 1001 contains at least one sheet material 2, a first surface 301 of the first pad plate 300 is in contact with a surface of the outermost sheet material 2. Figure 7 Figure 8 In some embodiments, as shown in Figs. 1 and 2, the sheet material carrier 10 further comprises a first pad plate 300. The first pad plate 300 is separate from the cavity 100 and is capable of being placed in the accommodating space 1001. The support 200 is further configured to support the first pad plate 300. When the accommodating space 1001 contains at least one sheet material 2, a first surface 301 of the first pad plate 300 is in contact with a surface of the outermost sheet material 2.
[0053] Exemplarily, the first surface 301 of the first pad plate 300 is in contact with the first surface 2001 of the outermost sheet material 2.
[0054] The first surface 301 of the first pad plate 300 shields the first surface 2001 of the outermost sheet material 2, so as to reduce the edge plating phenomenon of the first surface 2001 of the outermost sheet material 2.
[0055] In addition, when the first pad plate 300 and the sheet material 2 are simultaneously taken out of the accommodating space 1001, the sheet taking and placing assembly 20 is in contact with the first surface 301 of the first pad plate, so as to avoid the sheet taking and placing assembly 20 directly contacting the first surface 2001 of the sheet material 2, thereby avoiding the first surface 2001 of the sheet material 2 being marked or even the sheet material 2 being broken due to the sheet taking and placing assembly 20 applying too large force to the sheet material 2.
[0056] In some embodiments, when the accommodating space 1001 contains the sheet material 2, a vertical distance between the first side plate 130 and the second side plate 140 is less than 2 mm and greater than 1 mm than a size of the sheet material 2 in the first direction X1, the first direction X1 being a direction perpendicular to the second side plate 140 from the first side plate 130.
[0057] By reasonably setting the size of the accommodating space 1001 in the first direction X1, the sheet material 2 is facilitated to be placed in or taken out of the accommodating space 1001, and the accommodating space 1001 is facilitated to shield the non-cross section of the sheet material 2, so as to reduce the edge plating phenomenon of the non-cross section of the sheet material 2.
[0058] In some embodiments, as shown in Figure 4 and Figure 6 The bottom plate 110 includes a first sub-bottom plate 1110 and a second sub-bottom plate 1120. The first sub-bottom plate 1110 is connected with the first side plate 130 and the third side plate 150 respectively. The second sub-bottom plate 1120 is connected with the second side plate 140 and the third side plate 150 respectively. The first sub-bottom plate 1110 and the second sub-bottom plate 1120 form a first avoiding opening 1002. The third side plate 150 has a second avoiding opening 1003, which is in communication with the first avoiding opening 1002.
[0059] By setting the first avoiding opening 1002 and the second avoiding opening 1003, the sheet taking and placing assembly 20 is avoided so as to facilitate the sheet taking and placing assembly 20 to take and place the first backing plate 300, the second backing plate 400 and the sheet material 2.
[0060] Exemplarily, the two supports 200 are detachably connected with the first sub-bottom plate 1110 and the second sub-bottom plate 1120 respectively, so as to facilitate the replacement and maintenance of the supports 200.
[0061] Figure 9 The application scenario of the sheet conveying device provided by an embodiment of the present disclosure is shown. As shown in Figure 9 The sheet conveying device 1 includes the sheet carrier 10, the sheet taking and placing assembly 20 and the carrier conveying assembly 30 mentioned in the above embodiments. The sheet carrier 10 is configured to contain the sheet material 2, and the sheet taking and placing assembly 20 is configured to take and place the sheet material 2 in the sheet carrier 10. The carrier conveying assembly 30 is configured to compress the sheet material 2 contained in the sheet carrier 10 and convey the sheet carrier 10.
[0062] Exemplarily, as shown in Figure 4 The sheet carrier 10 further includes two handles 500, which are arranged at opposite edge regions of the top plate 120 and extend in the direction indicated by the access passage 101 to the third side plate 150. The carrier conveying assembly 30 conveys the sheet carrier 10 by grabbing the two handles 500. In addition, by reasonably setting the number and position of the handles 500, the conveying stability of the carrier conveying assembly 30 to the sheet carrier 10 is improved.
