[0005] The fixture assembly is used to pick up the solar cells in the solar cell storage assembly and move them towards the conveying assembly. The conveying assembly is used to convey the solar cells into the film laminating assembly. The pretreatment assembly is used to clean the surface of the solar cells, and at the same time, it can also clean the film laminating assembly and enable the solar cells to accurately enter the film laminating assembly.

[0006] Preferably, the support assembly includes four support feet and a power supply box. The four support feet are all placed on the ground, and the power supply box is fixedly installed on the top of the four support feet, and a power supply is stored inside the power supply box.

[0007] Preferably, the fixture assembly includes a fixture bracket, a first slide rail, a second slide rail and a plurality of fixtures. The fixture bracket is fixedly installed on the top of the power supply box, the first slide rail is fixedly installed on the top of the fixture bracket, the second slide rail is slidably installed in the first slide rail, and the plurality of fixtures are slidably installed in the second slide rail.

The storage box bracket is fixedly installed on the top of the power supply box, and the tops of the plurality of fixtures are placed on the storage box bracket. The solar cell storage box is installed on the top of the end of the storage box bracket away from the conveying assembly. The plurality of solar cells are stored in the solar cell storage box. An end cleaning brush is installed on the top of the side of the storage box bracket away from the conveying assembly.

[0009] Preferably, the packaging assembly includes a post-treatment bracket, a laminating member, a flattening member and a cleaning member. The post-treatment bracket is installed on the top of the conveying assembly, and the post-treatment bracket is connected to the film laminating bracket. The laminating member, the flattening member and the cleaning member are all installed on the top of the post-treatment bracket. The laminating member is installed at one end of the post-treatment bracket adjacent to the film laminating bracket. The flattening member is installed on the side of the laminating member away from the film laminating bracket. The cleaning member is installed at one end of the flattening member away from the laminating member.

[0010] The present invention also provides an automatic packaging process for solar cells, including the following steps:

[0011] Step S1: Turn on the control switch. The plurality of fixtures of the fixture assembly pick up the solar cells from the bottom of the solar cell storage box. After picking up the solar cells, the fixtures move the solar cells towards the conveying assembly side. While the solar cells are moving towards the conveying assembly side, the solar cells can abut against the end cleaning brush, and the end cleaning brush can clean the ends of the solar cells.

[0012] Step S2: When the solar cell moves to the end of the storage box bracket adjacent to the conveying component, the clamp will release the solar cell, and the toggle plate of the conveying component will move in the conveying slide rail, so that the toggle plate moves above the solar cell, and the pushing member moves downward to push the solar cell towards one end of the conveying platform adjacent to the film laminating component. While moving, when the solar cell passes through the top cleaning brush member, the top cleaning brush member can clean the top of the solar cell.

[0013] Step S3: After the solar cell passes through the top cleaning brush member and moves to one end adjacent to the film laminating component, the bottom of the solar cell will abut against the two buffer alignment plates, and the two buffer alignment plates respectively abut against the side walls of the solar cell. The solar cell continues to move, and the two buffer alignment plates flip, and finally the two buffer alignment plates respectively abut against the side walls of the solar cell. At the same time, when the two buffer alignment plates flip, the solar cell will squeeze the airbag, so that the air flow inside the airbag blows out from the cleaning hole, and the air flow blown out from the cleaning hole is used to blow and brush the conveying platform, so that the dust on the conveying platform falls from the dust removal grooves at the bottoms of the two side walls of the conveying platform.

[0014] Step S4: When the solar cell continues to move towards the film laminating component after squeezing the airbag, the solar cell will push the connecting rod to flip, so that the flattening block of the flattening member extends out of the storage groove. The flattening block is located above the film, and the air outlet exposes the opening facing the film. The first conductive sheet is conducted with the second conductive sheet, and the heating member starts to blow out hot air flow. The hot air flow blown out by the heating member blows out from the air outlet and enters the inside of the film. After the solar cell enters the film, the connecting rod returns to its original position under the action of the restoring force of the tension spring. At the same time, when the airbag follows the connecting rod to recover, the flattening block can flatten the film. After the solar cell enters the film, under the push of the film laminating moving member, it enters the packaging component, and the film laminating is completed under the action of the laminating member of the packaging component. Under the action of the flattening member, the lamination is further completed. Finally, under the cleaning of the cleaning member, the operation is completed.

[0015] The present invention provides a fixture. When the control switch is activated, multiple fixtures of the fixture assembly will move on the second slide rail, and the second slide rail will move within the first slide rail, enabling the multiple fixtures to move within the cassette bracket. As a result, the fixtures can pick up solar cells from the bottom of the solar cell cassette. After picking up the solar cells, the fixtures will move the solar cells towards the conveying assembly. While the solar cells are moving towards the conveying assembly, the solar cells can abut against the end cleaning brush, and the end cleaning brush can clean the ends of the solar cells to prevent dust and debris from adhering to the ends of the solar cells, thereby affecting the quality and appearance of the film laminating. By providing a top cleaning brush assembly, when the solar cells move to the end of the cassette bracket adjacent to the conveying assembly, the fixtures will release the solar cells. The toggle plate of the conveying assembly will move within the conveying slide rail, causing the toggle plate to move above the solar cells. The pushing member will move downward, pushing the solar cells towards one end of the conveying platform adjacent to the film laminating assembly. During the movement, when the solar cells pass through the top cleaning brush assembly, the top cleaning brush assembly can clean the tops of the solar cells to prevent dust and debris from adhering to the solar cells, thereby affecting the quality and appearance of the film laminating. By providing a buffer and alignment plate, after the solar cells pass through the top cleaning brush assembly and move to one end adjacent to the film laminating assembly, the bottoms of the solar cells will abut against the two buffer and alignment plates. The two buffer and alignment plates are used to buffer the solar cells to prevent the solar cells from moving too fast and generating a large arc when leaving the conveying platform, which may prevent the solar cells from entering the film properly. At the same time, the buffer and alignment of the solar cells can also correct the alignment of the solar cells, enabling the solar cells to enter the film while remaining in the same position. The solar cells continue to move, and the two buffer and alignment plates flip, eventually abutting against the side walls of the solar cells respectively. At the same time, when the two buffer and alignment plates clean the side walls of the solar cells, the solar cells will squeeze the airbag, causing the air flow inside the airbag to blow out from the cleaning holes. The air flow blown out from the cleaning holes is used to blow and brush the conveying platform, causing the dust and debris on the conveying platform to fall from the dust removal grooves at the bottoms of the two side walls of the conveying platform. By providing a heating element, when the solar cells continue to move towards the film laminating assembly after squeezing the airbag, the solar cells will push the connecting rod to flip, causing the smoothing block of the smoothing member to extend from the receiving groove, positioning the smoothing block above the film. The air outlet exposes the opening towards the film. The first conductive sheet and the second conductive sheet are electrically connected, and the heating element is activated to blow out hot air flow. The hot air flow blown out by the heating element enters the interior of the film through the air outlet. On one hand, the hot air flow is used to enlarge the opening of the film to ensure that the solar cells can enter the film. On the other hand, the hot air flow circulates within the film, softening the film. After the hot air flow stops blowing, the temperature of the film and the solar cells returns to normal and they contract, enabling the film and the solar cells to be simply adhered. This makes it easier for the film to be adhered in the next step. At the same time, the smoothing member can prevent the hot air flow flowing out of the air outlet from being too large, which may cause the opening of the film to be too large and is not conducive to the subsequent extrusion and adhesion.After the battery cell enters the film, the connecting rod returns to its original position under the action of the restoring force of the tension spring, and the airbag follows the connecting rod to recover. When the push-bevel surface abuts against the conveying platform, the smoothing block moves upward back to the storage slot, and the spring is compressed. At the same time, when the airbag follows the connecting rod to recover, the smoothing block can smooth the film to prevent the film opening from being too large, which is not conducive to film lamination. The structure of the present invention is ingenious, and can well enable the battery cell to enter the film, and through the hot air flow, the film is softened and drooped and solidified on the battery cell, making the next step of lamination simpler and more complete.

The flattening piece 83 is installed on the side of the fitting piece 82 away from the film pasting bracket 61. The cleaning piece 84 is installed at one end of the flattening piece 83 away from the fitting piece 82.

[0033] The present invention also provides an automatic packaging process for solar cells, including the following steps:

[0034] Step S1: Start the control switch (not shown in the figure). Multiple clamps 24 of the clamp component 20 clamp out the solar cell 33 from the bottom of the solar cell storage box 32. After clamping the solar cell 33, the clamp 24 moves the solar cell 33 toward the conveying component 50. While the solar cell 33 is moving toward the conveying component 50, the solar cell 33 can abut against the end cleaning brush 34, and the end cleaning brush 34 can clean the end of the solar cell 33.

[0035] Step S2: When the solar cell 33 moves to the end of the storage box bracket 31 adjacent to the conveying component 50, the clamp 24 releases the solar cell 33. The toggle plate 54 of the conveying component 50 moves in the conveying slide rail 52, so that the toggle plate 54 moves above the solar cell 33, and the pushing member 53 moves downward to push the solar cell 33 toward one end of the conveying platform 510 adjacent to the film pasting component 60. While moving, when the solar cell 33 passes through the top cleaning brush member 71, the top cleaning brush member 71 can clean the top of the solar cell 33.

[0036] Step S3: After the solar cell 33 passes through the top cleaning brush member 71 and moves to one end adjacent to the film pasting component 60, the bottom of the solar cell 33 abuts against two buffer alignment plates 73. The two buffer alignment plates 73 respectively abut against the side walls of the solar cell 33. The solar cell 33 continues to move, and the two buffer alignment plates 73 flip. Finally, the two buffer alignment plates 73 respectively abut against the side walls of the solar cell 33. At the same time, when the two buffer alignment plates 73 flip, the solar cell 33 squeezes the airbag 75, so that the air flow inside the airbag 75 blows out from the cleaning hole 750. The air flow blown out from the cleaning hole 750 is used to blow and brush the conveying platform 510, so that the dust on the conveying platform 510 falls from the dust removal grooves 512 at the bottoms of the two side walls of the conveying platform 510.

[0037] Step S4: After the battery cell 33 squeezes the airbag 75 and continues to move toward the film assembly 60, the battery cell 33 pushes the connecting rod 74 to flip, so that the smoothing block 754 of the smoothing member 753 extends from the storage groove 752, and the smoothing block 754 is located above the film 64. The air outlet 751 exposes the opening toward the film 64, the first conductive sheet is connected to the second conductive sheet, and the heating element 730 starts to blow out a hot air flow. The hot air flow blown out by the heating element 730 is blown out from the air outlet 751 into the interior of the film 64. After the battery cell 33 enters the film 64, the connecting rod 74 returns to its original position under the action of the restoring force of the tension spring. At the same time, when the airbag 75 follows the connecting rod 74 to recover, the smoothing block 754 can smooth the film 64. After entering the film 64, the battery cell 33 enters the packaging component 80 under the push of the film-sticking moving part 63, completes the film sticking under the action of the sticking part 82 of the packaging component 80, and further completes the sticking under the action of the flattening part 83.

The laminating part 82, the flattening part 83 and the cleaning part 84 are all installed on the top of the post-processing bracket 81, and the laminating part 82 is installed on the end of the post-processing bracket 81 adjacent to the film sticking bracket 61, the flattening part 83 is installed on the side of the laminating part 82 away from the film sticking bracket 61, and the cleaning part 84 is installed on the end of the flattening part 83 away from the laminating part 82.

[0039] During use: 1. A control switch is installed on the side wall of the power supply box 12. When the control switch is started, multiple clamps 24 of the clamp assembly 20 will move on the second slide rail 23, and the second slide rail 23 will move in the first slide rail 22, so that the multiple clamps 24 can move in the storage box bracket 31. Furthermore, the clamp 24 can pick up the battery cell 33 from the bottom of the battery cell storage box 32. After the clamp 24 picks up the battery cell 33, it will move the battery cell 33 towards the conveying assembly 50 side. While the battery cell 33 is moving towards the conveying assembly 50 side, the battery cell 33 can abut against the end cleaning brush 34, and the end cleaning brush 34 can clean the end of the battery cell 33 to prevent dust and debris from sticking to the end of the battery cell 33, thereby affecting the quality and appearance of the film pasting.

[0040] 2. When the battery cell 33 moves to the end of the storage box bracket 31 adjacent to the conveying assembly 50, the clamp 24 will release the battery cell 33. The toggle plate 54 of the conveying assembly 50 will move in the conveying slide rail 52, so that the toggle plate 54 moves above the battery cell 33, and the pushing member 53 moves downward to push the battery cell 33 towards one end of the conveying platform 510 adjacent to the film pasting assembly 60. While moving, when the battery cell 33 passes through the top cleaning brush member 71, the top cleaning brush member 71 can clean the top of the battery cell 33 to prevent dust and debris from sticking to the battery cell 33, thereby affecting the quality and appearance of the film pasting.

[0041] 3. After the battery cell 33 passes through the top cleaning brush member 71 and moves to one end adjacent to the film pasting assembly 60, the bottom of the battery cell 33 will abut against the two buffer and alignment plates 73. The two buffer and alignment plates 73 are used to buffer the battery cell 33 to prevent the battery cell 33 from moving too fast and generating a large arc when leaving the conveying platform 510, so that the battery cell 33 cannot enter the film 64 well. At the same time, buffering the battery cell 33 can also correct the position of the battery cell 33, so that the battery cell 33 can enter the film 64 at the same position. The battery cell 33 continues to move, and the two buffer and alignment plates 73 flip, and finally the two buffer and alignment plates 73 respectively abut against the side walls of the battery cell 33. At the same time, when the two buffer and alignment plates 73 clean the two side walls of the battery cell 33, the battery cell 33 will squeeze the airbag 75, so that the air flow inside the airbag 75 blows out from the cleaning hole 750. The air flow blown out from the cleaning hole 750 is used to blow the conveying platform 510, so that the dust on the conveying platform 510 falls from the dust removal grooves 512 at the bottom of the two side walls of the conveying platform 510.

[0042] 4. When the solar cell 33 continues to move towards the film laminating assembly 60 after squeezing the airbag 75, the solar cell 33 will push against the connecting rod 74 and turn over, so that the smoothing block 754 of the smoothing member 753 extends out of the storage groove 752. The smoothing block 754 is located above the film 64, and the air outlet 751 exposes the opening facing the film 64. The first conductive sheet is conducted with the second conductive sheet, and the heating member 730 is activated to blow out hot air flow. The hot air flow blown out by the heating member 730 blows out from the air outlet 751 and enters the inside of the film 64. On the one hand, the flowing air flow is used to make the opening of the film 64 larger to ensure that the solar cell 33 enters the film 64. On the other hand, the hot air flow flows in the film 64 to soften the film 64. After the film 64 is softened, it droops on the solar cell 33. After stopping blowing the hot air flow, the temperatures of the film 64 and the solar cell 33 recover and contract, so that the film 64 and the solar cell 33 can be simply attached, and further, when the film 64 is laminated in the next step, the lamination is simpler. At the same time, the smoothing member 753 can prevent the hot air flow flowing out from the air outlet 751 from being too large, so that the opening of the film 64 is too large, which is not conducive to the subsequent extrusion lamination. After the solar cell 33 enters the film 64, the connecting rod 74 returns to its original position under the action of the restoring force of the tension spring, and the airbag 75 follows the connecting rod 74 to recover. When the pushing inclined surface 755 abuts against the conveying platform 510, the smoothing block 754 moves upward and returns to the storage groove 752, and the spring is compressed. At the same time, when the airbag 75 follows the connecting rod 74 to recover, the smoothing block 754 can smooth the film 64 to prevent the opening of the film 64 from being too large, which is not beneficial to film lamination. After the solar cell 33 enters the film 64, under the push of the film laminating moving member 63, it enters the packaging assembly 80. Under the action of the laminating member 82 of the packaging assembly 80, the film lamination is completed. Under the action of the flattening member 83, the lamination is further completed. Finally, under the cleaning of the cleaning member 84, the operation is completed.

[0043] In the present invention, by providing the fixture 24, when the control switch is activated, multiple fixtures 24 of the fixture assembly 20 will move on the second slide rail 23, and the second slide rail 23 moves in the first slide rail 22, enabling the multiple fixtures 24 to move in the storage box bracket 31. Further, the fixture 24 can pick up the battery slice 33 from the bottommost part of the battery slice storage box 32. After picking up the battery slice 33, the fixture 24 moves the battery slice 33 towards the conveying assembly 50 side. While the battery slice 33 is moving towards the conveying assembly 50 side, the battery slice 33 can abut against the end cleaning brush 34, and the end cleaning brush 34 can clean the end of the battery slice 33, preventing dust and debris from sticking to the end of the battery slice 33, thereby affecting the quality and appearance of the film pasting. By providing the top cleaning brush member 71, when the battery slice 33 moves to the end of the storage box bracket 31 adjacent to the conveying assembly 50, the fixture 24 will release the battery slice 33. The toggle plate 54 of the conveying assembly 50 will move in the conveying slide rail 52, causing the toggle plate 54 to move above the battery slice 33, and the pushing member 53 moves downward to push the battery slice 33 towards one end of the conveying platform 510 adjacent to the film pasting assembly 60. During the movement, when the battery slice 33 passes through the top cleaning brush member 71, the top cleaning brush member 71 can clean the top of the battery slice 33, preventing dust and debris from sticking to the battery slice 33, thereby affecting the quality and appearance of the film pasting. By providing the buffer and deviation correction plates 73, after the battery slice 33 passes through the top cleaning brush member 71 and moves to one end adjacent to the film pasting assembly 60, the bottom of the battery slice 33 will abut against the two buffer and deviation correction plates 73. The two buffer and deviation correction plates 73 are used to buffer the battery slice 33, preventing the battery slice 33 from having too high a speed and thus generating a large arc when leaving the conveying platform 510, which may cause the battery slice 33 to not enter the film 64 well. At the same time, buffering the battery slice 33 can also correct the deviation of the battery slice 33, enabling the battery slice 33 to enter the film 64 while maintaining the same position. The battery slice 33 continues to move, and the two buffer and deviation correction plates 73 flip, and finally the two buffer and deviation correction plates 73 respectively abut against the side walls of the battery slice 33. At the same time, when the two buffer and deviation correction plates 73 clean the two side walls of the battery slice 33, the battery slice 33 will squeeze the airbag 75, causing the air flow inside the airbag 75 to blow out from the cleaning holes 750. The air flow blown out from the cleaning holes 750 is used to blow the conveying platform 510, causing the dust and debris on the conveying platform 510 to fall from the dust removal grooves 512 at the bottoms of the two side walls of the conveying platform 510.By setting the heating element 730, when the battery cell 33 continues to move towards the film laminating assembly 60 after squeezing the airbag 75, the battery cell 33 will push against the connecting rod 74 and flip, causing the flattening block 754 of the flattening member 753 to extend from the receiving groove 752, such that the flattening block 754 is located above the film 64, and the air outlet 751 exposes the opening facing the film 64. The first conductive sheet and the second conductive sheet are electrically connected, and the heating element 730 is activated to blow out hot air flow. The hot air flow blown out by the heating element 730 blows out from the air outlet 751 and enters the interior of the film 64. On the one hand, the flowing air flow is used to make the opening of the film 64 larger to ensure that the battery cell 33 enters the film 64. On the other hand, the hot air flow flows in the film 64, causing the film 64 to soften, such that after the film 64 softens, it droops onto the battery cell 33. After stopping the blowing of the hot air flow, when the temperatures of the film 64 and the battery cell 33 recover and contract, the film 64 and the battery cell 33 can be simply adhered, making it easier to adhere the film 64 in the next step. At the same time, the flattening member 753 can prevent the hot air flow flowing out from the air outlet 751 from being too large, thereby causing the opening of the film 64 to be too large, which is not conducive to the subsequent squeezing and adhering. After the battery cell 33 enters the film 64, the connecting rod 74 returns to its original position under the action of the restoring force of the tension spring, and the airbag 75 follows the connecting rod 74 to recover. When the pushing inclined surface 755 abuts against the conveying platform 510, the flattening block 754 moves upward and returns to the receiving groove 752, and the spring is compressed. At the same time, when the airbag 75 follows the connecting rod 74 to recover, the flattening block 754 can flatten the film 64 to prevent the opening of the film 64 from being too large, which is not beneficial for film laminating. The structure of the present invention is ingenious, and it can well enable the battery cell 33 to enter the film 64, and through the hot air flow, the film 64 is softened, droops, and solidifies on the battery cell 33, making it easier and more complete to adhere in the next step.

6. An automatic packaging process for solar cell wafers, characterized in that, using the automatic packaging machine for solar cell wafers as described in claim 5, the packaging process includes the following steps: Step S1: Turn on the control switch. Multiple clamps (24) of the clamp assembly (20) will pick up the solar cell (33) from the bottom of the solar cell storage box (32). After picking up the solar cell (33), the clamp (24) will move the solar cell (33) towards the conveying assembly (50). While the solar cell (33) is moving towards the conveying assembly (50), the solar cell (33) can abut against the end cleaning brush (34), and the end cleaning brush (34) can clean the end of the solar cell (33). Step S2: When the solar cell (33) moves to the end of the storage box bracket (31) adjacent to the conveying assembly (50), the clamp (24) will release the solar cell (33). The toggle plate (54) of the conveying assembly (50) will move in the conveying slide rail (52) so that the toggle plate (54) moves above the solar cell (33), and the pushing member (53) moves downward to push the solar cell (33) towards one end of the conveying platform (510) adjacent to the film laminating assembly (60). While moving, when the solar cell (33) passes through the top cleaning brush member (71), the top cleaning brush member (71) can clean the top of the solar cell (33). Step S3: After the solar cell (33) passes through the top cleaning brush member (71), when the solar cell (33) moves to one end adjacent to the film laminating assembly (60), the solar cell (33) will abut against two buffer and alignment plates (73). The two buffer and alignment plates (73) respectively abut against the side walls of the solar cell (33). The solar cell (33) continues to move, and the two buffer and alignment plates (73) flip. Eventually, the two buffer and alignment plates (73) respectively abut against the side walls of the solar cell (33). At the same time, when the two buffer and alignment plates (73) flip, the solar cell (33) will squeeze the airbag (75), so that the air flow inside the airbag (75) blows out from the cleaning hole (750). The air flow blowing out from the cleaning hole (750) is used to blow the conveying platform (510), so that the dust on the conveying platform (510) falls from the dust removal grooves (512) at the bottoms of the two side walls of the conveying platform (510). Step S4: When the solar cell (33) continues to move towards the film laminating assembly (60) after squeezing the airbag (75), the solar cell (33) will push against the connecting rod (74) to flip, so that the flattening block (754) of the flattening member (753) extends out of the storage groove (752). The flattening block (754) is located above the film (64), and the air outlet (751) exposes the opening facing the film (64). The first conductive sheet and the second conductive sheet are conducted, and the heating member (730) starts to blow out hot air flow. The hot air flow blown out by the heating member (730) blows out from the air outlet (751) and enters the inside of the film (64). After the solar cell (33) enters the film (64), the connecting rod (74) returns to its original position under the action of the restoring force of the tension spring. At the same time, when the airbag (75) follows the connecting rod (74) to recover, the flattening block (754) can flatten the film (64). After the solar cell (33) enters the film (64), it is pushed by the film laminating moving member (63) and enters the packaging assembly (80). Under the action of the fitting member (82) of the packaging assembly (80), film laminating is completed. Under the action of the flattening member (83), further fitting is completed. Finally, under the cleaning of the cleaning member (84), the operation is completed.
