[0060] In view of the technical problem that the existing wafer packaging machine requires manual assistance to complete wafer packaging, this application provides a wafer packaging machine. Refer to Figure 1 , the wafer packaging machine includes:

[0061] Auxiliary material picking and placing device 1, used to place auxiliary materials at the upper and lower ends of the wafer group respectively;

[0062] Wafer arranging device 2, used to regularize the wafer group so that the wafers in the wafer group are arranged neatly;

[0065] The second transfer device 6 is used to transfer the solar cell group at the cell arranging device 2 to the packaging device 4.

[0066] The working process of the solar cell packaging machine is as follows:

[0067] First, the auxiliary material picking and placing device 1 places the auxiliary materials at the upper and lower ends of the solar cell group; then, the first transfer device 5 transfers the solar cell group and the auxiliary materials on the solar cell group to the cell arranging device 2, and the cell arranging device 2 arranges the solar cells; finally, the second transfer device 6 transfers the arranged solar cell group and the auxiliary materials on the solar cell group to the packaging device 4, and the packaging device 4 packages the solar cells.

[0068] As described above, the solar cell packaging machine provided by the present application can automatically complete steps such as placing auxiliary materials, arranging cells, and packaging for solar cells, and has advantages such as high automation degree and high working efficiency.

[0069] It should be noted that the solar cell group is composed of a plurality of solar cells arranged in layers, and the function of the auxiliary material is to prevent the upper and lower end faces of the solar cell group from being exposed, protecting the solar cells from damage. The auxiliary material can be one or more of sulfur-free paper, hollow board, bubble film, or other protective materials, which are not limited herein.

[0070] Referring to Figure 2 , the auxiliary material picking and placing device 1 includes a material box conveying mechanism 11, an auxiliary material storage mechanism 12, and an auxiliary material transfer mechanism 13, where:

[0071] The material box conveying mechanism 11 is used to convey an empty material box 100 or a material box 100 containing a solar cell group to the auxiliary material placing station;

[0072] The auxiliary material storage mechanism 12 is used to store auxiliary materials;

[0073] The auxiliary material transfer mechanism 13 is used to pick up the auxiliary materials in the auxiliary material storage mechanism 12 and place them in the material box 100 at the auxiliary material placing station.

[0074] Continuing to refer to Figure 2 , the material box conveying mechanism 11 includes a first conveying component 111, a second conveying component 112, and a lifting component 113, where: the first conveying component 111 and the second conveying component 112 are arranged in parallel in the height direction; the lifting component 113 can realize the transfer of the material box 100 between the first conveying component 111 and the second conveying component 112.

[0075] In this embodiment, both the first conveying assembly 111 and the second conveying assembly 112 are belt conveyors.

[0076] Referring to Figure 3 and Figure 4 , the lifting assembly 113 includes a slide rail 1131, a slide block 1132, a lifting platform 1133 and a lifting drive source 1134, where: the slide rail 1131 is parallel to the vertical direction, the slide block 1132 is slidably mounted on the slide rail 1131, the lifting platform 1133 is fixedly arranged on the slide block 1132, and the lifting drive source 1134 is used to drive the slide block 1132 to slide on the slide rail 1131. In this embodiment, the lifting drive source 1134 is specifically a motor.

[0077] Referring to Figure 4 , the lifting platform 1133 includes a lifting conveyor belt 11331, and one end of the lifting conveyor belt 11331 can be docked with the first conveying assembly 111 or the second conveying assembly 112. Specifically, when the lifting drive source 1134 drives the lifting platform 1133 to lift to a set height, the lifting platform 1133 is docked with the first conveying assembly 111; when the lifting drive source 1134 drives the lifting platform 1133 to descend to a set height, the lifting platform 1133 is docked with the second conveying assembly 112. The lifting platform 1133 further includes a motor for driving the lifting conveyor belt 11331 to rotate forward and backward, so as to realize the transfer of the material box 100 between the lifting platform 1133 and the first conveying assembly 111 or the second conveying assembly 112.

[0078] It should be noted that when the lifting platform 1133 is lifted to the set height, the material box 100 on the lifting platform 1133 is at the auxiliary material placing station.

[0079] Continuing to refer to Figure 2 , the working process of the auxiliary material picking and placing device 1 is as follows:

[0080] First, the first conveying component 111 conveys the empty bin 100 to the lifting component 113; then, the auxiliary material transfer mechanism 13 takes the auxiliary materials in the auxiliary material storage mechanism 12 and places them in the bin 100; after the auxiliary materials are placed, the lifting component 113 transfers the bin to the second conveying component 112, and the second conveying component 112 conveys the bin to the battery cell placement station; after the battery cells are placed, the first conveying component 111 conveys the bin 100 to the lifting component 113 again. Subsequently, the auxiliary material transfer mechanism 13 takes the auxiliary materials in the auxiliary material storage mechanism 12 again and places them in the bin 100. Thus, a feeding process is completed. After the feeding is completed, the bin 100 contains auxiliary materials, a battery cell group, and auxiliary materials in sequence from bottom to top. Through the above process, the reciprocating conveyance of the bin 100 between the auxiliary material placement station and the battery cell placement station is realized, so that auxiliary materials can be placed at both the upper and lower ends of the battery cell group.

[0081] Referring to Figure 5 and Figure 6 , the first transfer device 5 includes a first robot and a bin clamping component 51. The bin clamping component 51 is installed at the power output end of the first robot and is used for clamping the bin 100, and the bin 100 is used for carrying a battery cell group. The bin clamping component 51 includes a pair of bin clamping jaws and a first jaw driving source for driving the pair of bin clamping jaws to close or open. During the working process, the bin clamping component 51 can clamp the bin 100 containing the battery cell group and auxiliary materials at the auxiliary material taking and placing device 1 and transfer the bin 100 to the cell arranging device 2.

[0082] Referring to Figure 7 , the cell arranging device 2 includes:

[0083] A flipping platform 21, which is used for carrying and fixing the bin 100 containing the battery cell group, and has a first state in a horizontal setting and a second state in a vertical setting;

[0084] A flipping driving mechanism 22, which is used for driving the flipping platform 21 to switch between the first state and the second state;

[0085] A material blocking mechanism 23, which includes a floating blocking member 231; when the flipping platform 21 switches between the first state and the second state, the blocking member 231 can block at the opening of the bin 100;

[0086] A blowing mechanism 24, which is used for blowing air into the bin 100.

[0087] The working process of the cell arranging device 2 is as follows:

[0088] Referring to Figure 7 , in the initial state, the flipping platform 21 is in the first state, and the first transfer device 5 places the bin 100 containing the battery cell group and auxiliary materials on the flipping platform 21;

[0089] Referring to Figure 8 , then, the flipping drive mechanism 22 drives the flipping platform 21 to rotate from the horizontal setting (the first state) to the vertical setting (the second state). When the flipping platform 21 rotates by a certain angle but does not fully rotate to the second state, the blocking member 231 moves to the opening of the bin 100 to block the battery wafers in the bin 100 and prevent the battery wafers from falling;

[0090] The flipping drive mechanism 22 drives the flipping platform 21 to continue rotating until the flipping platform 21 rotates to the vertical setting (the second state). During this process, by the gravity of the battery wafers themselves, the whole battery wafers naturally fall to the bottom of the bin 100; at this time, the blowing mechanism 24 is aligned with the bin 100 on the flipping platform 21;

[0091] Subsequently, the blowing mechanism 24 blows air into the bin 100 through the gaps on the side wall of the bin 100. The air flow blows the battery wafers apart, so that each battery wafer can fall to the bottom of the bin 100 under the action of gravity, thereby enabling the battery wafers to be neatly arranged;

[0092] After the wafer sorting is completed, the flipping drive mechanism 22 drives the flipping platform 21 to rotate from the vertical setting (the second state) to the horizontal setting (the first state). The neatly arranged battery wafers fall to the bottom of the bin 100 under the action of gravity, and thus the wafer sorting step of the battery wafers is completed.

[0093] In this embodiment, when the flipping platform 21 is in the vertical setting (the second state), one edge of the bin 100 is at the bottommost. When the flipping platform 21 rotates to the horizontal setting (the first state), the battery wafers are neatly arranged at a corner of the bin 100.

[0094] Continuing to refer to Figure 7 and Figure 8 , a clamping member 211 and a clamping drive source 212 for driving the clamping member 211 to move in a direction approaching or away from the bin 100 are provided on the flipping platform 21. The clamping member 211 is used to press the bin 100 against the flipping platform 21.

[0095] Furthermore, the wafer sorting device 2 further includes a wafer sorting bracket 25. The flipping drive mechanism 22, the material blocking mechanism 23, and the blowing mechanism 24 are all installed on the wafer sorting bracket 25. The power output end of the flipping drive mechanism 22 is connected to the flipping platform 21, and the wafer sorting device 2 is formed into a whole through the wafer sorting bracket 25.

[0096] Further, a support roller 213 is also provided on the flipping platform 21. The support roller 213 is arranged at the bottom of the flipping platform 21 in the second state, and the support roller 213 can support the material box 100 when the flipping platform 21 is in the second state to prevent the material box 100 from falling. In this embodiment, the number of the support rollers 213 is two, and the support effect on the material box 100 can be improved by multiple support rollers 213.

[0097] Further, the air blowing mechanism 24 includes at least one air nozzle 241 for blowing air into the material box 100; when the number of the air nozzles 241 is multiple, the air nozzles 241 are distributed along the circumferential direction of the flipping platform 21 in the second state. Multiple air nozzles 241 can blow air into the material box 100 from multiple angles, further improving the effect of sheet sorting. In this embodiment, there are four gaps on the side wall of the material box 100. Correspondingly, the number of the air nozzles 241 is four, and when the flipping platform 21 is in the second state, the four air nozzles 241 correspond to the four gaps one by one.

[0098] On the basis of the above structure, the air blowing mechanism 24 further includes at least one air nozzle driving source 242. The air nozzle driving source 242 corresponds to the air nozzle 241 one by one, and the air nozzle driving source 242 is used to drive the corresponding air nozzle 241 to reciprocate horizontally. During the process of air blowing and sheet sorting, the air nozzle driving source 242 drives the air nozzle 241 to reciprocate horizontally, thereby effectively regularizing the battery sheets.

[0099] Continue to refer to Figure 7 and Figure 8 , the material blocking mechanism 23 further includes:

[0100] A fixed seat 232;

[0101] A blocking driving source 233, which is slidably installed on the fixed seat 232 along the direction of approaching or departing from the flipping platform 21, and is used to drive the blocking member 231 to move along the direction of approaching or departing from the flipping platform 21;

[0102] An elastic member 234, which is connected between the fixed seat 232 and the blocking driving source 233, and is used to provide an elastic force for driving the blocking driving source 233 to approach the flipping platform 21.

[0103] The working principle of the material blocking mechanism 23 is as follows:

[0104] Refer to Figure 7 , in the initial state, the flipping platform 21 is horizontally arranged, and the piston rod of the blocking driving source 233 retracts; refer to Figure 2, then, the flipping drive mechanism 22 drives the flipping platform 21 to rotate from the horizontal setting to the vertical setting. When the flipping platform 21 rotates by a certain angle, the piston rod of the blocking drive source 233 extends, driving the blocking member 231 to move to the opening of the material box 100; then, the flipping drive mechanism 22 drives the flipping platform 21 to continue rotating. During this process, under the action of the elastic member 234, the blocking member 231 can be adaptively adjusted horizontally according to the flipping degree of the battery cell. This flexible clamping method can avoid damaging the battery cell; subsequently, the air blowing mechanism 24 blows air into the material box 100 through the gap on the side wall of the material box 100, and the blocking member 231 can float adaptively during the process of air blowing and sheet arranging, further avoiding damaging the battery cell; after the sheet arranging is completed, the flipping drive mechanism 22 drives the flipping platform 21 to rotate from the vertical setting to the horizontal setting. When the flipping platform 21 rotates by a certain angle, the piston rod of the blocking drive source 233 retracts, driving the blocking member 231 away from the material box 100 so as not to interfere with the rotation of the flipping platform 21.

[0105] Continue to refer to Figure 6 , the battery cell packaging machine further includes a detection device 3 for detecting the form of the battery cell group; the second transfer device 6 is also used to sequentially transfer the battery cell group between the sheet arranging device 2, the detection device 3, and the encapsulation device 4.

[0106] Continue to refer to Figure 6 , the battery cell packaging machine further includes a recycling conveyor 7 that extends from the detection device 3 to the manual operation area; the second transfer device 6 is also used to transfer the battery cell group that does not meet the packaging requirements at the detection device 3 to the recycling conveyor 7. In this embodiment, the recycling conveyor 7 is specifically a belt conveyor, which is used to convey the battery cell group that does not meet the packaging requirements to the manual operation area, and the operator trims or removes the battery cell group that does not meet the packaging requirements.

[0107] Refer to Figure 9 , the second transfer device 6 includes a second robot and a battery cell clamping assembly 61, and the battery cell clamping assembly 61 is installed at the power output end of the second robot and is used to clamp the battery cell group. The second transfer device 6 can take out the battery cell group that has completed sheet arranging together with the auxiliary materials on the battery cell group from the material box 100 and place it at the detection device 3; according to the detection result of the detection device 3, the second transfer device 6 can transfer the battery cell group that meets the packaging requirements together with the auxiliary materials on the battery cell group from the detection device 3 to the encapsulation device 4, and can also transfer the battery cell group that does not meet the packaging requirements together with the auxiliary materials on the battery cell group from the detection device 3 to the recycling conveyor 7.

[0108] Furthermore, the cell gripping assembly 61 includes four cell grippers evenly distributed around the same center line and a second gripper driving source for driving the four cell grippers to close or separate. During the process of the cell gripping assembly 61 gripping the cell group, the four grippers can center and regularize the cell group, thereby further improving the neatness of the cell group.

[0109] Referring to Figure 10 and Figure 11 , the dotted area in the figure represents the cell group. The detection device 3 includes:

[0110] A cell stage 31 for carrying the cell group;

[0111] A side detection assembly 32 for obtaining a first image of the side of the cell group and transmitting the first image to the control and recognition system;

[0112] A corner detection assembly 33 for obtaining a second image of the corners of the cell group and transmitting the second image to the control and recognition system.

[0113] The working process of the detection device 3 is as follows:

[0114] First, the second transfer device 6 places the cell group after sheet sorting and the auxiliary materials on the cell group on the cell stage 31; then, the side detection assembly 32 and the corner detection assembly 33 take pictures of the side and corners of the cell group in sequence and transmit the captured images to the control and recognition system; the control and recognition system can identify and analyze the images to determine whether there are missing cells, breakages, etc. in the cell group.

[0115] As an optional embodiment, the number of the side detection assemblies 32 is four and they respectively correspond to photographing the four sides of the cell group. The number of the corner detection assemblies 33 is four and they respectively correspond to photographing the four corners of the cell group.

[0116] As another optional embodiment, referring to Figure 11 and Figure 12 , the number of the side detection assemblies 32 is two and they are respectively arranged opposite to the two sides of the cell stage 31; the number of the corner detection assemblies 33 is two and they are respectively arranged opposite to the two corners of the cell stage 31; the detection device 3 further includes a rotation driving assembly 34 for driving the cell stage 31 to rotate. The working principle of this embodiment is: first, the two side detection assemblies 32 and the two corner detection assemblies 33 respectively detect the forms of two sides and two corners of the cell group; after the detection is completed, the rotation driving assembly 34 drives the cell stage 31 to rotate 180°, and then, the two side detection assemblies 32 and the two corner detection assemblies 33 respectively detect the forms of the other two sides and the other two corners of the cell group.

[0117] Optionally, the rotation drive assembly 34 includes a motor, a speed reducer, and a speed reducer support. Among them, the motor, the speed reducer, and the solar cell stage 31 are sequentially connected in transmission, and the speed reducer is fixedly arranged on the speed reducer support.

[0118] Continue to refer to Figure 12 , each group of side detection components 32 includes a side shooting camera 321 and a first camera drive source (not shown in the drawings). Among them: the shooting end of the side shooting camera 321 is oppositely arranged with a side of the solar cell group on the solar cell stage 31; the first camera drive source is used to drive the side shooting camera 321 to reciprocate along the length direction of the side of the solar cell group corresponding to the side shooting camera 321.

[0119] Furthermore, each group of corner detection components 33 includes a corner shooting camera 331 and a second camera drive source (not shown in the drawings). Among them: the shooting end of the corner shooting camera 331 is oppositely arranged with a corner of the solar cell group on the solar cell stage 31; the second camera drive source is used to drive the corner shooting camera 331 to move along the direction approaching or departing from the corner of the solar cell group corresponding to the corner shooting camera 331.

[0120] Optionally, the first camera drive source and the second camera drive source are cylinders or motors.

[0121] The setting of the first camera drive source increases the shooting range of the side shooting camera 321, making the image captured by the side shooting camera 321 more comprehensive. The setting of the second camera drive source enables the corner shooting camera 331 to avoid the moving path of the side shooting camera 321 during the detection process of the side detection components 32. At the same time, the corner shooting camera 331 is as close as possible to the corner of the solar cell group during the detection process to obtain a clearer image.

[0122] The encapsulation device 4 in this embodiment is of an existing structure and will not be elaborated here.

[0123] Refer to Figure 1 and Figure 2 , the specific working process of the solar cell packaging machine provided in this embodiment is as follows:

[0124] S1: After the equipment is powered on, the lifting platform 1133 is lifted to be docked with the first conveying component 111, and the first conveying component 111 conveys an empty material box 100 to the lifting platform 1133;

[0125] S2: The auxiliary material transfer mechanism 13 grabs the auxiliary materials and places them in the material box 100 on the lifting platform 1133;

[0126] S3: The lifting platform 1133 descends to dock with the second conveying component 112. The lifting platform 1133 transfers the bin 100 containing auxiliary materials onto the second conveying component 112, and the second conveying component 112 conveys the bin 100 to the battery cell placement station;

[0127] S4: Manually or via a robot, stack the battery cells on the bin 100 at the battery cell placement station. At this time, the bin 100 contains auxiliary materials and a battery cell group from bottom to top in sequence;

[0128] S5: Manually or via a robot, place the bin 100 containing battery cells back on the first conveying component 111. The lifting platform 1133 rises to dock with the first conveying component 111, and the first conveying component 111 conveys the bin 100 containing battery cells onto the lifting platform 1133;

[0129] S6: The auxiliary material transfer mechanism 13 grabs the auxiliary materials again and places them in the bin 100 on the lifting platform 1133. At this time, the bin 100 contains auxiliary materials, a battery cell group, and auxiliary materials from bottom to top in sequence;

[0130] S7: The first transfer device 5 transfers the loaded bin 100 to the flipping platform 21 of the cell arranging device 2, and the cell arranging device 2 arranges the battery cells;

[0131] S8: The second transfer device 6 takes out the arranged battery cell group from the bin 100 and transfers it to the battery cell carrier 31 of the detection device 3, and the detection device 3 detects whether the battery cell group meets the packaging requirements;

[0132] If the battery cell group meets the packaging requirements, proceed to step S9;

[0133] If the battery cell group does not meet the packaging requirements, proceed to step S10;

[0134] S9: The second transfer device 6 grabs the battery cell group on the battery cell carrier 31 and transfers it to the encapsulation device 4. The first transfer device 5 grabs the empty bin 100 on the flipping platform 21 onto the lifting platform 1133, and then return to step S2;

[0135] S10: The first transfer device 5 grabs the empty bin 100 on the flipping platform 21 onto the recycling conveying device 7. The second transfer device 6 grabs the battery cell group on the battery cell carrier 31 into the empty bin 100 on the recycling conveying device 7, and the recycling conveying device 7 conveys the bin 100 to the manual operation area for manual trimming; Meanwhile, the first conveying component 111 conveys an empty bin 100 onto the lifting platform 1133, and then return to step S2.

[0136] It can be understood that during actual use, the operator can adjust the working steps of the cell packaging machine according to personal preferences. For example, in step S10, the program can be adjusted so that the second transfer device 6 first places the cell group that does not meet the packaging requirements into the empty bin 100 on the flipping platform 21, and then the first transfer device 5 grabs the bin 100 and places it on the recycling conveyor 7.

[0137] As described above, the cell packaging machine provided by the present application can automatically complete steps such as placing auxiliary materials for cells, aligning cells, detecting, removing unqualified products, and encapsulating, with little need for manual participation, and has advantages such as high automation and high working efficiency.
