Description

Technical Field

[0001] The utility model belongs to the technical field of solar cell preparation, and particularly relates to a conveying mechanism suitable for solar cells and a gluing device including the conveying mechanism. The conveying mechanism can be used for loading, conveying or unloading solar cells. Background Art

[0002] In the production process of solar cells, a process of gluing the solar cells is involved. For example, in the process of preparing grid lines on the solar cells by electroplating method, it is necessary to pre-apply glue on the side of the solar cells to form a protective layer to protect the side of the solar cells from electroplating. For conventional rectangular solar cells, it is necessary to apply glue on the upper and lower sides of the four edges and chamfers and other edge structures in the length and width directions, and this process is also called the gluing treatment process of solar cells.

[0003] After the gluing treatment, there is glue on the four edges of the solar cells. When unloading, usually a manipulator directly adsorbs the middle area of the upper surface of the solar cells from the carrier. In this way, during the transmission of the solar cells, it is necessary to wait until the manipulator completely adsorbs the solar cells before the carrier can return to carry other solar cells that have just completed gluing, and the production rhythm is slow.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Such as Figures 1-4As shown in the figure, the glue - coating device 1 of the battery cell in this embodiment includes a glue - coating mechanism 2, a conveying mechanism 3, and a blanking mechanism 4. The glue - coating mechanism 2 and the blanking mechanism 4 are arranged in sequence along the conveying direction of the battery cell 7. The glue - coating mechanism 2 is used for applying glue to the edge of the battery cell 7. The conveying mechanism 3 is arranged below the glue - coating mechanism 2 and is used for conveying the battery cell 7 into the glue - coating mechanism 2 for glue - coating and then conveying it to the blanking mechanism 4. The blanking mechanism 4 is used for blanking the battery cell 7 after glue - coating.

[0026] The glue - coating mechanism 2 in this embodiment includes a glue - coating member 21 and a driver for driving the glue - coating member 21 to move horizontally and vertically. The glue - coating member 21 of the glue - coating mechanism 2 is correspondingly arranged on the moving path of the battery cell 7 and is arranged corresponding to the edge of the battery cell 7, and is used for applying glue to the side surface and the upper and lower surfaces near the edge of the battery cell 7. In this embodiment, the glue - coating member 21 of the glue - coating mechanism 2 can specifically adopt the structure and scheme disclosed in the Chinese patent document CN221132955U.

[0027] The conveying mechanism 3 in this embodiment includes a base 9, a support member 5 fixed on the base 9, and at least two groups of bearing components 6 capable of moving relative to the support member 5. The bearing components 6 are used for bearing the battery cell 7 and driving the battery cell 7 to move. The support member 5 is used for supporting the battery cell 7. Multiple groups of bearing components 6 alternately convey the battery cell 7 with the support member 5. The support member 5 in this embodiment is used for receiving the battery cell 7 conveyed by the bearing component 6 to realize the conveyance of the battery cell 7. The support member 5 is arranged between the glue - coating mechanism 2 and the blanking mechanism 4.

[0028] Each bearing component 6 includes a bearing table 61 and a driver for driving the bearing table 61 to move. The driver includes a first driver for moving in the first direction and a second driver 8 for moving in the second direction. The first direction is the conveying direction of the battery cell 7, and the second direction is perpendicular to the first direction. In this embodiment, the first direction is the horizontal direction, and the second direction is the up - and - down direction. By setting drivers moving in different directions, it is realized that there is no interference when the multiple bearing tables 61 move reciprocally. And the size of the bearing table 61 needs to be smaller than the size of the battery cell 7 to facilitate the glue - coating member 21 to apply glue to the edge of the battery cell 7 and avoid interference between the bearing table 61 and the glue - coating member 21, which affects the glue - coating of the battery cell 7 and the adhesion after glue - coating. In some embodiments, the first direction and the second direction may not be strictly perpendicular, but intersect at an angle close to 90°.

[0029] In this embodiment, the first driver is fixed on the base 9, and the second driver 8 moves synchronously with the carrier 61. When the solar cell 7 is being conveyed, the carrier 61 reciprocates relative to the support member 5 on the base 9. The two sets of carrier assemblies 6 move interactively and alternately convey the solar cell 7 to the support member 5. In this embodiment, for the two sets of carrier assemblies 6, the carrier 61 is located above the base 9 and is arranged corresponding to the support member 5. In this embodiment, for the two sets of carrier assemblies 6, the first driver and the second driver 8 corresponding to one set of carrier assemblies 6 are installed on one side of the base 9, and the first driver and the second driver 8 corresponding to the other set of carrier assemblies 6 are installed on the opposite side of the base 9 to avoid interference between the drivers when the two sets of carrier assemblies 6 move.

[0030] As Figure 4 shown, in this embodiment, the support member 5 includes a support rod 51, a support base 53, and a buffer member 52. The buffer member 52 is arranged on the surface of the support rod 51 that contacts the solar cell 7 and is preferably made of a flexible material to avoid damaging the solar cell 7. The support base 53 is used to be fixed on the base 9.

[0031] When the solar cell 7 and the support member 5 approach each other, at least a part of the support member 5 is inserted into the carrier 61. Specifically, a groove 62 is provided on the carrier 61 and is opened along the moving direction of the solar cell 7. When the solar cell 7 is conveyed between the support member 5 and the carrier 61, at least a part of the support rod 51 is inserted into the groove 62 along the length direction. The height of the support rod 51 is less than the depth of the groove 62 so that the support rod 51 can be inserted into the groove 62.

[0032] When the solar cell 7 is being conveyed, the support rod 51 is located between the bottom surface of the groove 62 and the bottom surface of the solar cell 7 so that the support rod 51 can be inserted into the groove 62. At the same time, after the support rod 51 receives the solar cell 7, the height of the carrier 61 drops so that the solar cell 7 remains on the support rod 51.

[0033] In this embodiment, at least two grooves 62 are provided on the carrier 61, and the support member 5 has at least two corresponding support rods 51 to stably convey and receive the solar cell 7.

[0034] In this embodiment, the blanking mechanism 4 includes a rotating base and adsorption components evenly spaced on the rotating base. The adsorption components are used to adsorb the solar cell 7 on the support rod 51 and drive the rotation by the rotating base to the next station to wait for processing or conveyance. The blanking mechanism 4 in this embodiment can specifically adopt the structure and solution disclosed in the Chinese patent document CN220781055U.

[0035] The following briefly describes the working process of the glue coating device 1 for the solar cell 7 in this embodiment:

[0036] A carrier 61 carries the solar cell 7 and moves it towards the blanking mechanism 4. When passing through the gluing mechanism 2, the gluing member 21 applies glue to the edge of the solar cell 7. During the gluing process, the carrier 61 continues to move forward while carrying the solar cell 7 to complete the gluing.

[0037] When the carrier 61 reaches the position of the support member 5, the support rod 51 is located between the bottom surface of the groove 62 and the bottom surface of the solar cell 7. Then the carrier 61 continues to move forward while carrying the solar cell 7 so that the support rod 51 is inserted into the groove 62. After the support rod 51 passes through the groove 62, the second driver 8 controls the height of the carrier 61 to decrease so that the solar cell 7 remains on the support rod 51 and is completely supported by the support rod 51 and waits to be adsorbed by the blanking mechanism 4.

[0038] After that, the first driver drives the carrier 61 to move away from the blanking mechanism 4 and repeats the above steps. At the same time, while the first driver drives the carrier 61 to move away from the blanking mechanism 4, another carrier 61 also carries another solar cell 7 and moves it towards the blanking mechanism 4, following the same process as above.

[0039] After the solar cell 7 is supported on the support rod 51, it is adsorbed by the adsorption component of the blanking mechanism 4 and transferred to the next station for blanking or waiting for processing or transportation.

[0040] For the conveying mechanism 3 of the solar cell 7 in this embodiment, a fixed support member 5 and a carrier assembly 6 that moves relative to the support member 5 are provided. Among them, the carrier assembly 6 only transports the solar cell 7, and the support member 5 receives the solar cell 7 and waits to be adsorbed by the blanking mechanism 4, enabling the alternating carrier assembly 6 to continuously convey with the support member 5 and wait for the next conveyance or process on the support member 5 or the carrier assembly 6, which can effectively improve the conveyance efficiency during the preparation of the solar cell 7, reduce the blanking time, and increase the production rhythm.
