DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present disclosure.
[0029] Figure 1 Fig. 1 is a schematic view of a sheet handling system according to an embodiment of the present disclosure. The direction indicated by arrow X is the first direction, and the direction indicated by arrow Y is the vertical direction. The first direction X and the vertical direction Y are perpendicular, and will not be emphasized separately hereinafter.
[0030] The sheet guiding mechanism according to the present disclosure can be applied to a sheet loading and unloading system Figure 1 The sheet guiding mechanism 1 is applied to a sheet loading and unloading system 10, which includes a sheet inserting mechanism 3, a carrying mechanism 2 and the sheet guiding mechanism 1 arranged in sequence from top to bottom along a vertical direction Y. The sheet inserting mechanism 3 is configured to insert a sheet downwardly into the carrying mechanism 2 along the vertical direction Y. The carrying mechanism 2 includes a bottom bar 21 located on a side away from the sheet inserting mechanism 3, and the bottom bar 21 is provided with a plurality of first tooth grooves 211 arranged along a first direction X. The sheet guiding mechanism 1 is configured to lift the sheet in the carrying mechanism 2, or carry the sheet inserted by the sheet inserting mechanism 3, and place the sheet in the first tooth grooves 211, so as to play a role of intermediate transfer.
[0031] It can be understood that the carrying mechanism 2 can be a boat structure for carrying a plurality of sheets, and the boat structure includes two side plates 23 arranged at intervals along the first direction X, and a plurality of top bars 22 and a plurality of bottom bars 21 connected between the two side plates 23, and the top bars 22 are located above the bottom bars 21 along the vertical direction Y. For example, the number of the top bars 22 and the bottom bars 21 is both set to two, so as to form a square frame structure, and the space enclosed by the square frame is used for carrying the sheets. The bottom bar 21 is provided with a plurality of first tooth grooves 211 on a side facing the sheet inserting mechanism 3, and the plurality of first tooth grooves 211 are arranged along the first direction X. The top bars 22 can also be provided with tooth grooves. In the process of inserting the sheet into the boat structure by the sheet inserting mechanism 3, the sheet will first enter the tooth grooves of the top bars 22, and can continue to move downwardly relative to the tooth grooves, and in this downward movement, the sheet is carried to the sheet guiding mechanism 1, and then the sheet guiding mechanism 1 transfers the sheet into the first tooth grooves 211 of the bottom bars 21.
[0032] Optionally, the sheet can be a solar cell sheet, which needs to be processed through different processes to finally become a solar cell product that can be used. The shape of the solar cell sheet can be, for example, rectangular, square, circular, etc., without specific limitation. In the present disclosure, for the convenience of description, the solar cell sheet is set to be square, and the square solar cell sheet is simply referred to as a silicon sheet 4, which will not be emphasized separately in the following.
[0033] Optionally, the plurality of first tooth grooves 211 are arranged along the first direction X, and the cross section of the first tooth groove 211 can be, for example, V-shaped, U-shaped, etc. The opening of the first tooth groove 211 has a first size in the first direction X. The first size can also be understood as the distance between the top of the adjacent first tooth grooves 211 in the first direction X. The first size can be matched according to the thickness of the silicon sheet 4, the inclination angle of the silicon sheet 4 relative to the vertical plane when placed, etc., without specific limitation.
[0034] Specifically, the sheet guiding mechanism 1 comprises a first carrier 13, a first driving member 14 and a second driving member 15, the sheet guiding mechanism 1 is arranged on the side of the carrier mechanism 2 away from the sheet inserting mechanism 3 in the vertical direction Y; the first carrier 13 is provided with a plurality of second tooth grooves 13a arranged in the first direction X on the side facing the sheet inserting mechanism 3, the second tooth grooves 13a are configured to carry the silicon wafer 4; the first driving member 14 is connected with the first carrier 13 and is configured to drive the first carrier 13 to move in the first direction X, so that the second tooth grooves 13a correspond to the silicon wafers 4 one by one in the vertical direction Y, or the centers of the second tooth grooves 13a are aligned with the centers of the first tooth grooves 211; the second driving member 15 is configured to drive the first carrier 13 to ascend and descend in the vertical direction Y, so that the first carrier 13 lifts the silicon wafer 4 in the first tooth groove 211 or places the silicon wafer 4 in the second tooth groove 13a into the first tooth groove 211.
[0035] It can be understood that the first carrier 13 is located between the two bottom rods 21 in the second direction Z and between the two side plates 23 in the first direction X, and the two bottom rods 21 and the two side plates 23 of the boat structure enclose an inlet and outlet in communication with the space. The first carrier 13 is located directly below the inlet and outlet, and when the second driving member 15 drives the first carrier 13 to ascend and descend in the vertical direction Y, at least the second tooth grooves 13a of the first carrier 13 can enter or move out of the space through the inlet and outlet.
[0036] Optionally, the sheet inserting mechanism 3 can be arranged with a plurality of silicon wafers 4 in the first direction X for inserting the silicon wafers into the space of the boat structure, and the specific structure of the sheet inserting mechanism 3 is not described in detail.
[0037] When the sheet inserting mechanism 3 inserts the vertically placed silicon wafer 4 into the boat structure, since the bottom rod 21 of the boat structure is far away from the position of the sheet inserting mechanism 3, and the opening size of the first tooth groove 211 of the bottom rod 21 in the first direction X is small, when the silicon wafer 4 has a positional deviation in the first direction X or a process deformation problem, it is difficult for the lower edge of the silicon wafer 4 to be inserted into the first tooth groove 211. Therefore, the sheet guiding mechanism 1 provided by the embodiment of the present disclosure can first drive the first carrier 13 to move in the first direction X by the first driving member 14 to align the centers of the second tooth grooves 13a with the centers of the silicon wafers 4 in the sheet inserting mechanism 3, and then drive the first carrier 13 to extend into the space from the inlet and outlet in the vertical direction Y by the second driving member 15, and make the second tooth grooves 13a higher than the first tooth grooves 211, so that the lower edge of the silicon wafer 4 can extend into the second tooth groove 13a during the sheet inserting process. After the sheet inserting mechanism 3 completes the sheet inserting, the first driving member 14 can drive the first carrier 13 to move in the first direction X to align the centers of the second tooth grooves 13a with the centers of the first tooth grooves 211, and the second driving member 15 drives the first carrier 13 to descend, and during the descending process, the sheet guiding mechanism 1 can transfer the silicon wafer 4 from the second tooth groove 13a to the first tooth groove 211.
[0038] The sheet guiding mechanism 1 provided by the embodiment of the present disclosure utilizes the cooperation of the first driving member 14 driving the lateral movement of the first carrier 13 and the second driving member 15 driving the vertical movement of the first carrier 13, so that when the second tooth groove 13a is used to carry the sheet mechanism 3, the second tooth groove 13a is adjusted to correspond to the silicon wafer 4 to be inserted, and when the second tooth groove 13a is used to further guide the silicon wafer 4 inserted into the boat structure into the first tooth groove 211 of the bottom rod 21, the second tooth groove 13a is adjusted to correspond to the first tooth groove 211, so that the silicon wafer 4 is smoothly guided into the first tooth groove 211 of the bottom rod 21. Such a cooperation structure enables the inserted silicon wafer 4 to be guided into the first tooth groove 211 of the bottom rod 21 even if there is a deviation or process deformation, so as to reduce the probability of carding and fragmentation in the subsequent process.
[0039] Optionally, the first tooth groove 211 has a first opening, and the second tooth groove 13a has a second opening, and the size of the second opening in the first direction X is greater than the size of the first opening in the first direction X, so as to facilitate the smooth guidance of the inserted silicon wafer 4 into the second tooth groove 13a and from the second tooth groove 13a to the first tooth groove 211.
[0040] In some optional embodiments, the sheet guiding mechanism 1 further comprises a base 11 and a second carrier 12, the base 11 is detachably connected to the workbench below the boat structure, the second carrier 12 is connected to the base 11, and the second driving member 15 is installed to the base 11 or the second carrier 12; the first driving member 14 is installed to the second carrier 12, and the first carrier 13 is movably connected above the second carrier 12 in the first direction X. The base 11 and the second carrier 12 are provided to facilitate the adaptive adjustment of the installation position of the sheet guiding mechanism on the workbench according to the specific position of the boat structure, and facilitate the installation of the first driving member 14 and the second driving member 15, so that the first carrier 13 can realize the movement in the first direction X and the lifting in the vertical direction Y.
[0041] Optionally, the second carrier 12 comprises a second carrier plate 121, which is movably connected above the base 11 in the vertical direction Y, and the first carrier 13 is movably connected to the second carrier plate 121 in the first direction X.

Figure 3 The figure shows a schematic view of the adjusting block in the second position in the sheet guiding mechanism provided by an embodiment of the present disclosure. Figure 2 The figure shows a partial enlarged view of part A in the sheet guiding mechanism.
[0043] Figure 4Fig. 6 shows a schematic view of the sheet guiding mechanism according to an embodiment of the present disclosure, wherein the adjusting block is located at the second position. Figure 5 Fig. 7 shows a schematic view of the sheet guiding mechanism according to an embodiment of the present disclosure. Figure 4 Fig. 8 shows a partial enlarged view of the B part of the sheet guiding mechanism. Figure 6 Fig. 6 shows a schematic view of the sheet guiding mechanism according to an embodiment of the present disclosure, wherein the adjusting block is located at the second position.
[0044] As shown in Fig. 6, the first carrier 13 includes a first carrier plate 131, one or more supporting tooth bars 1311 and an adjusting block 132, the first carrier plate 131 is connected with the supporting tooth bars 1311 arranged along the second direction Z on one side of the sheet guiding mechanism 3, each supporting tooth bar 1311 has a second tooth groove 13a, the adjusting block 132 is fixedly connected to the first carrier plate 131, and the first driving member 14 is connected with the adjusting block 132 to drive the first carrier plate 131 and the supporting tooth bars 1311 to move along the first direction X, wherein the supporting tooth bars 1311 are arranged in a staggered manner with the bottom bars, and the supporting tooth bars 1311 are located between the two bottom bars at the edge. Figures 2 to 6 In some embodiments, the first center 2a of the carrier mechanism 2 is positionally offset from the second center 3a of the sheet inserting mechanism 3 along the first direction X, i.e., the first center 2a and the second center 3a have a first offset distance L1 therebetween, the sheet guiding mechanism 1 can be installed on the workbench with the carrier mechanism 2 as a reference, the third center 1a of the sheet guiding mechanism 1 is aligned with the first center 2a, and the second tooth grooves 13a are one-to-one corresponding to the first tooth grooves 211 of the bottom bars 21, at this time, the adjusting block 132 is located at the first position, which is also the initial position of the adjusting block 132. When the first driving member 14 drives the adjusting block 132 to move to the second position, the first center 2a and the second center 3a coincide, the distance between the first position and the second position is the first offset distance L1, by driving the adjusting block 132 to move to the second position through the first driving member 14, the second tooth grooves 13a can be one-to-one corresponding to the offset silicon wafer 4, so that the silicon wafer 4 can be guided into the second tooth grooves 13a. And by driving the adjusting block 132 to reset to the initial position through the first driving member 14, the second tooth grooves 13a can be one-to-one corresponding to the first tooth grooves 211, so as to guide the offset silicon wafer 4 into the first tooth grooves 211.

When the silicon wafer 4 inserted by the sheet inserting mechanism 3 is a process-deformed silicon wafer, there is a deformation distance between the position where the lower edge of the silicon wafer 4 is deformed and the position of the undeformed area of the silicon wafer 4 in the first direction X. When the first driving member 14 drives the adjusting block 132 to move to the second position, the second tooth grooves 13a correspond to the deformed lower edge of the silicon wafer 4 one by one, and the distance between the first position and the second position is the deformation distance, so that the silicon wafer 4 can be guided into the second tooth grooves 13a. And the first driving member 14 drives the adjusting block 132 to reset to the initial position, so that the second tooth grooves 13a can correspond to the first tooth grooves 211 one by one, so as to guide the deformed silicon wafer 4 into the first tooth grooves 211.

When the second tooth grooves 13a correspond to the silicon wafer 4 in the vertical direction Y and / or the centers of the second tooth grooves 13a are aligned with the centers of the first tooth grooves 211, the first driving member 14 drives the first bearing member 13 to abut against the first positioning surface 133a, specifically, the surface of the adjusting block 132 abuts against the first positioning surface 133a, at this time, the adjusting block 132 is in the second position. The first positioning member 133 can make the first driving member 14 quickly position the adjusting block 132 to the second position when driving the adjusting block 132 to move, and ensure the alignment accuracy of the second tooth grooves 13a and the silicon wafer 4.

For example, only the first positioning member 133 is provided, the first driving member 14 is provided as a driving cylinder 141, the end of a cylinder rod 142 of the driving cylinder 141 is connected to the adjusting block 132, the driving cylinder 141 can drive the cylinder rod 142 to extend in the first direction X, in the process of driving the cylinder rod 142 to extend by the driving cylinder 141, the cylinder rod 142 drives the adjusting block 132 to move in the first direction X to abut against the first positioning member 133 and then stop, at this time, the adjusting block 132 is in the second position, the driving cylinder 141 can also drive the cylinder rod 142 to retract to an initial state, so that the adjusting block 132 returns to the initial position, i.e., the initial position. In this cooperation structure, the second positioning member 134 does not need to be provided, so as to reduce the complexity of the sheet material guiding mechanism 1 and save costs.

The guide plates 122 have inclined track grooves 122a, which extend along the direction of the track grooves 122a and include at least a third position B1 and a fourth position B2, pointing from the third position B1 to the fourth position B2. The direction of the track grooves 122a is inclined upward. The second driving member 15 includes a roller 152 and a driving part 151. The roller 152 rolls into the track groove 122a. The driving part 151 is disposed on the base 11 and is configured to drive the roller 152 to move in a first direction X, so that the roller 152 moves in the track groove 122a. The movement of the roller 152 from the third position B1 to the fourth position B2 can drive the second support plate 121 to descend in the vertical direction Y, and the movement of the roller 152 from the fourth position B2 to the third position B1 can drive the second support plate 121 to rise in the vertical direction Y. By cooperating with the inclined track groove 122a, the lateral movement of the roller 152 driven by the drive unit 151 along the first direction X is converted into the movement in the vertical direction Y, thus saving the space occupied by the sheet guide mechanism 1 in the vertical direction Y.
[0055] In addition, when the drive unit 151 is unable to work due to power failure, the roller 152 and the track groove 122a can remain in the corresponding engagement position and will not fall due to power failure of the drive unit 151, thus ensuring the safety of the silicon wafer 4 carried by the second tooth groove 13a.
[0056] Optionally, the driving part 151 can be a transversely placed air cylinder, the output end of the air cylinder is connected to the roller 152 to drive the roller 152 to reciprocate in the first direction X by the jacking action of the air cylinder in the transverse direction.
[0057] In some optional embodiments, the number of the second driving members 15 includes two or more, and the plurality of second driving members 15 are arranged in the first direction X at intervals in the accommodation space 11a, and the number of the guide plates 122 can match the number of the second driving members 15. For example, the number of the guide plates 122 is two, and the two guide plates 122 are arranged at positions close to the two ends of the second bearing plate 121 respectively, and the two driving parts 151 are arranged at positions corresponding to the two guide plates 122 respectively, so that the two driving parts 151 are used to jack up the second bearing member 12 and the first bearing member 13 at the same time, to be suitable for the gusset of a larger boat structure, and the use range of the sheet guiding mechanism 1 is improved.
[0058] Optionally, one of the second bearing member 12 and the base 11 is provided with a second sliding rail 16 extending in the vertical direction Y, and the other is provided with a second sliding block 17 matched with the second sliding rail 16, and the relative movement of the second sliding block 17 and the second sliding rail 16 in the vertical direction Y can drive the second bearing member 12 to slide relative to the base 11 in the vertical direction Y. It should be emphasized that the matched second sliding rail 16 and the second sliding block 17 can be arranged as a group, or as a plurality of groups arranged at intervals in the first direction X, to provide stable guiding action for the second bearing member 12 and the first bearing member 13 in the vertical direction Y, without specific limitation.
[0059] The working principle of the sheet guiding mechanism 1 is as follows: Figure 1 In the initial state, the sheet guiding mechanism 1 is arranged below the bearing mechanism 2, the roller 152 is located at the fourth position B2, and the first driving member 14 drives the adjusting block 132 to be located at the first position as the initial position, at this time, the second tooth groove 13a is located below the first tooth groove 211 of the bottom rod 21 in the vertical direction Y, and the center of the second tooth groove 13a is respectively aligned with the center of the first tooth groove 211. Figure 2 Before the gusset mechanism 3 inserts the gusset, the second driving member 15 is driven to drive the second bearing member 12 and the first bearing member 13 to rise together in the vertical direction Y, until the second tooth groove 13a is higher than the first tooth groove 211 in the vertical direction Y, at this time, the roller 152 moves from the fourth position B2 to the third position B1 along the track groove 122a. Figure 4The first driving member 14 drives the adjusting block 132 to move along the first direction X, so that the adjusting block 132 moves from the first position to the second position, and the second toothed groove 13a corresponds one-to-one with the silicon wafer 4 of the insertion mechanism 3. The insertion mechanism 3 inserts the silicon wafer 4 into the carrying mechanism 2, and the silicon wafer 4 continues to move downward from the toothed groove of the top rod 22 until the lower edge of the silicon wafer 4 extends into the second toothed groove 13a. After the insertion is completed, the first driving member 14 drives the adjusting block 132 to reset to the first position along the first direction X, so that the second toothed groove 13a is above the first toothed groove 211 and the centers of the two are aligned. Figure 8 The second driving member 15 drives the roller 152 to move from the third position B1 back to the fourth position B2. During the process of the second carrier 12 and the first carrier 13 descending in the vertical direction Y, the silicon wafer 4 in the second tooth groove 13a is guided into the first tooth groove 211, so that the silicon wafer 4 is inserted into the first tooth groove 211 of the bottom rod 21.
