[0041] In order to solve the problem of poor production quality of solar cells in the prior art, the present application provides a carrying device.

[0042] like Figures 1 to 8 As shown, the bearing device includes a bottom plate 10, a side plate 20, a plurality of bearing structures 30 and a plurality of supporting structures 40. The side plate 20 is arranged on the bottom plate 10. The plurality of bearing structures 30 are arranged at intervals along the length direction or width direction of the side plate 20, and a bearing recess 31 is formed around two adjacent bearing structures 30 and at least part of the side wall of the side plate 20, and the bottom wall of the bearing recess 31 contacts the part to be carried 1 to carry the part to be carried 1. The plurality of supporting structures 40 are arranged on the bottom plate 10, and the plurality of supporting structures 40 are arranged one by one corresponding to the plurality of bearing recesses 31. Among them, the supporting structure 40 has an initial position and a supporting position. When the supporting structure 40 is in the initial position, the supporting structure 40 has a preset distance with the part to be carried 1. When the supporting structure 40 is in the supporting position, the supporting structure 40 abuts against the bottom of the part to be carried 1 away from the bearing recess 31 to support the part to be carried 1.

[0043] Applying the technical solution of this embodiment, the side plate 20 of the load-bearing device is arranged on the bottom plate 10. A plurality of load-bearing structures 30 are arranged at intervals along the length direction or width direction of the side plate 20, and a load-bearing recess 31 is formed around two adjacent load-bearing structures 30 and at least part of the side wall of the side plate 20, and the bottom wall of the load-bearing recess 31 is in contact with the part to be carried 1 to carry the part 1. A plurality of support structures 40 are arranged on the bottom plate 10, and the plurality of support structures 40 are arranged one-to-one with the plurality of load-bearing recesses 31. Among them, the support structure 40 has an initial position and a support position, and when the support structure 40 is in the initial position, the support structure 40 has a preset distance with the part to be carried 1. When the support structure 40 is in the support position, the support structure 40 abuts against the bottom of the part to be carried 1 away from the load-bearing recess 31 to support the part to be carried 1. In this way, when the staff places the solar cell on the carrying device, the support structure 40 is in the initial position, which is convenient for the staff to easily and accurately place the solar cell in the carrying recess 31, so that the carrying recess 31 can preliminarily position and carry the solar cell. Afterwards, the support structure 40 is in the supporting position, supporting the part of the solar cell away from the carrying recess 31, so that the solar cell is doubly supported, achieving the uniformity and reliability of the carrying of the carrying device, avoiding the phenomenon that the solar cell is affected by its own gravity and causes the middle part of the solar cell to fall, adjusting the overall levelness of the solar cell, thereby reducing the phenomenon of warping of the solar cell during the heating and curing process, improving the production quality of the solar cell, and thus solving the problem of poor production quality of solar cells in the prior art.

[0044] In this embodiment, the component 1 to be carried is a solar cell.

[0045] In this embodiment, a plurality of bearing structures 30 are arranged at intervals along the length direction of the side plate 20 .

[0046] In this embodiment, the length direction of the side plate 20 is perpendicular to the bottom plate 10 .

[0047] Specifically, Figure 2 As shown in FIG. 1 , when the support structure 40 is in the initial position, the plane where the support structure 40 is located is below the plane where the bottom wall of the bearing recess 31 is located. Figure 3 As shown, when the support structure 40 is in the supporting position, the plane where the support structure 40 is located is parallel to the plane where the bottom wall of the bearing recess 31 is located, or the plane where the support structure 40 is located is above the plane where the bottom wall of the bearing recess 31 is located.

[0048] like Figure 1As shown, there are at least two side panels 20, and the bearing device also includes a top plate 50, which is connected to one end of at least two side panels 20 away from the bottom plate 10, and a bearing space 51 is formed between at least two side panels 20 and at least part of the top plate 50, and at least part of the bearing structure 30 and at least part of the support structure 40 are both located in the bearing space 51. In this way, the two side panels 20 arranged on the bottom plate 10 can bear the two edges of the solar cell, and the two side panels 20 combined with the support structure 40 can triple support the solar cell, further adjusting the overall horizontality of the solar cell and improving the bearing uniformity of the bearing device. At the same time, the setting method of the bearing space 51 realizes the bearing stability of the bearing device, which can ensure the stability and safety of the placement of the solar cell, thereby ensuring the stability of the solar cell during the curing and heating process, and improving the production quality of the solar cell.

[0049] In the present application, the number of side panels 20 provided is two.

[0050] It should be noted that the number of side panels 20 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of side panels 20 is three, four, six, eight, or more.

[0051] like Figure 1 As shown, the bearing device also includes a driving structure 60, which is arranged on the top plate 50 and / or the bottom plate 10, and the driving structure 60 is drivingly connected to the multiple supporting structures 40 to drive the supporting structures 40 to switch between the initial position and the supporting position. In this way, the staff can realize the movement of the supporting structure 40 by starting the driving structure 60, without the need for manual control by the staff, thereby reducing the labor intensity of the staff and improving the work efficiency of the staff. At the same time, the driving structure 60 can provide accurate and efficient driving force, which is conducive to achieving the support accuracy and convenience of the supporting structure 40.

[0052] like Figure 1 and Figure 4 As shown, the bearing device also includes a transmission structure 70, which is adjustably arranged on the bottom plate 10, and the transmission structure 70 is columnar, and multiple support structures 40 are arranged at intervals along the length direction or width direction of the transmission structure 70. Among them, the driving structure 60 is drivingly connected with the transmission structure 70 to drive the transmission structure 70 to reciprocate along the first preset direction to drive the support structure 40 to move. In this way, the arrangement of the transmission structure 70 enables the driving structure 60 to drive multiple support structures 40 to move at the same time, realizes the adjustment of the horizontality of multiple solar cells, improves the bearing efficiency of the bearing device, and also improves the production quality of multiple solar cells.

[0053] In this embodiment, the transmission structure 70 is vertically disposed on the base plate 10 , and the first preset direction is the extension direction of the transmission structure 70 itself.

[0054] In this embodiment, the driving structure 60 is disposed on the base plate 10 .

[0055] In one embodiment, the driving structure 60 is one of a pneumatic cylinder and a hydraulic cylinder, one of the cylinder body or the piston rod of the driving structure 60 is disposed on the bottom plate 10, and the other of the cylinder body or the piston rod of the driving structure 60 is drivingly connected to the transmission structure 70. In this way, the driving structure 60 can provide a stable and efficient driving force, and ensure the movement stability of the transmission structure 70.

[0056] In another embodiment, Figures 1 to 3 As shown, the bearing device also includes a transmission structure 70, and the transmission structure 70 includes a transmission shaft 71 and a sleeve portion 72. The driving structure 60 is connected to the transmission shaft 71 to drive the transmission shaft 71 to rotate. The sleeve portion 72 is sleeved on the transmission shaft 71 and threadedly matched with the transmission shaft 71. The sleeve portion 72 is block-shaped, and multiple support structures 40 are arranged at intervals along the length direction or width direction of the sleeve portion 72. In the process of the sleeve portion 72 passing through the bottom plate 10 and moving along the extension direction of the transmission shaft 71, the sleeve portion 72 drives the support structure 40 to move. In this way, the driving structure 60 is one of a motor and a rotary cylinder. The driving structure 60 drives the transmission shaft 71 of the transmission structure 70 to rotate, and through the cooperation between the transmission shaft 71 and the sleeve portion 72, the driving of the multiple support structures 40 is realized. At the same time, the cooperation relationship between the transmission shaft 71 and the sleeve portion 72 makes the setting position of the driving structure 60 more flexible, and also reduces the installation space of the driving structure 60, thereby realizing the structural miniaturization of the bearing device.

[0057] Specifically, the bearing device further includes a bearing 100 , which is disposed on the bottom plate 10 and the top plate 50 to be connected to the transmission shaft 71 to improve the rotation smoothness and stability of the transmission shaft 71 .

[0058] Specifically, the shaft sleeve portion 72 is in the shape of a rectangular block, and the base plate 10 is provided with a through hole matching the shaft sleeve portion 72 to limit and stop the shaft sleeve portion 72, thereby avoiding the rotation of the shaft sleeve portion 72 itself, so that the shaft sleeve portion 72 can move along the extension direction of the transmission shaft 71, thereby ensuring the transmission reliability of the transmission structure 70.

[0059] Specifically, the plurality of support structures 40 are arranged at intervals along the length direction of the sleeve portion 72 .

[0060] In this embodiment, the length direction of the shaft sleeve portion 72 is perpendicular to the bottom plate 10 .

[0061] like Figures 4 to 8As shown, the bearing device also includes a matching structure 80 and a limiting structure 90. The matching structure 80 is arranged at one end of the transmission structure 70 away from the bottom plate 10. The limiting structure 90 can be movably arranged on the top plate 50. Among them, when the support structure 40 is in the initial position, the limiting structure 90 avoids the matching structure 80. When the support structure 40 is in the supporting position, the limiting structure 90 abuts against the side of the matching structure 80 close to the bottom plate 10 to limit the transmission structure 70. In this way, when the driving structure 60 drives the transmission structure 70 to drive the support structure 40 to move to the supporting position, the limiting structure 90 abuts against the matching structure 80, so that the transmission structure 70 and the top plate 50 can be closely matched, avoiding the influence of the external environment and the gravity of the solar cell, which causes the shaking of the transmission structure 70, ensuring the stability of the transmission structure 70, and then ensuring the support stability and reliability of the support structure 40 when it is in the supporting position.

[0062] like Figures 6 to 8 As shown, the top plate 50 has a mounting recess 52, and the mounting recess 52 has a first matching portion 521, and the limiting structure 90 includes a sliding portion 91 and a limiting portion 92. The sliding portion 91 has a second matching portion 911, one of the first matching portion 521 and the second matching portion 911 is a protrusion, and the other of the first matching portion 521 and the second matching portion 911 is a recess, and the protrusion extends into the recess and is slidably arranged along the extension direction of the recess. The limiting portion 92 is arranged at one end of the sliding portion 91 close to the matching structure 80, and the limiting portion 92 abuts against the side of the matching structure 80 close to the bottom plate 10. In this way, the cooperation between the first matching portion 521 and the second matching portion 911, on the one hand, realizes the sliding connection between the limiting structure 90 and the top plate 50; on the other hand, it makes the structure of the first matching portion 521 and the second matching portion 911 more flexible and diverse, and improves the processing flexibility of the staff. At the same time, the limiting structure 90 achieves an abutting connection with the matching structure 80 through the limiting portion 92 , thereby ensuring the structural stability of the transmission structure 70 and improving the supporting reliability of the supporting structure 40 .

[0063] In this embodiment, the first matching portion 521 is a recessed portion, and the second matching portion 911 is a protrusion.

[0064] Specifically, the sliding portion 91 includes a main body, and the second matching portion 911 passes through the main body to be slidably matched with the first matching portion 521 .

[0065] like Figures 7 and 8As shown, there are at least two limiting parts 92, and a receiving space 921 is formed between at least two limiting parts 92. The matching structure 80 includes a main body 81 and an abutting part 82. The main body 81 is arranged on the transmission structure 70. The abutting part 82 is arranged on a side of the main body 81 away from the transmission structure 70. When the supporting structure 40 is in the supporting position, the receiving space 921 is used to accommodate the main body 81, and at least two limiting parts 92 are abutted against a side of the abutting part 82 close to the transmission structure 70. In this way, the matching structure 80 realizes the connection with the transmission structure 70 through the main body 81, and realizes the connection with the limiting structure 90 through the abutting part 82. At the same time, when the support structure 40 supports the solar cell, the accommodating space 921 formed by the two limiting parts 92 matches the main body 81, and the limiting part 92 abuts against the abutting part 82, so that the cooperation between the limiting structure 90 and the matching structure 80 is closer, thereby improving the structural stability of the transmission structure 70 and improving the supporting stability and reliability of the support structure 40.

[0066] In the present application, the number of the limiting parts 92 is two.

[0067] It should be noted that the number of the limit parts 92 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of the limit parts 92 is three, four, six, eight, or more.

[0068] like Figures 1 to 4 As shown, the support structure 40 is columnar, and the length L of the support structure 40 satisfies: 17mm≤L≤21mm. In this way, the above arrangement increases the direct contact area between the support structure 40 and the solar cell, further improves the support stability and reliability of the support structure 40 for the solar cell, further improves the levelness of the solar cell, and improves the production quality of the solar cell.

[0069] In this embodiment, the length L satisfies: L=19 mm, so as to ensure that the value of L is most appropriate.

[0070] like Figure 2 and Figure 3As shown, the support structure 40 is columnar, and along the extension direction perpendicular to the support structure 40, the cross-sectional diameter D of the support structure 40 satisfies: 0.8mm≤D≤1.2mm; wherein, the distance H between two adjacent support structures 40 satisfies: 2.0mm≤H≤2.4mm. In this way, the above arrangement enables the support structure 40 to support the solar cell while ensuring that the solar cell is smoothly placed in the bearing recess 31, thereby ensuring the bearing reliability and smoothness of the bearing device. At the same time, the above arrangement of the support structure 40 can also provide support for the solar cell while ensuring the heating area of ​​the solar cell and the heating reliability of the solar cell.

[0071] In this embodiment, the cross-sectional diameter D satisfies: D=1 mm, so as to ensure that the value of the cross-sectional diameter D is most appropriate.

[0072] In this embodiment, the distance H satisfies: H=2.2 mm, so as to ensure that the value of the distance H is most appropriate.

[0073] Specifically, when the staff needs to heat and cure the solar cell, the staff will place the solar cell horizontally into the bearing space 51, and place the two sides of the solar cell into the bearing recess 31, so that the bearing recess 31 can provide preliminary support for the solar cell. At this time, the support structure 40 is in the initial position, and the limiting structure 90 avoids the matching structure 80. After that, the staff starts the driving structure 60 to drive the transmission structure 70 to move, and the transmission structure 70 drives the support structure 40 to move to the supporting position. The support structure 40 abuts against the bottom of the solar cell to provide further support for the solar cell. At this time, the limiting structure 90 abuts against the side of the matching structure 80 close to the bottom plate 10 to avoid shaking of the transmission structure 70 and improve the support stability of the support structure 40 when it is in the supporting position.

[0074] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0075] The side plates of the bearing device are arranged on the bottom plate. A plurality of bearing structures are arranged at intervals along the length direction or width direction of the side plate, and a bearing recess is formed around two adjacent bearing structures and at least part of the side wall of the side plate, and the bottom wall of the bearing recess contacts the part to be carried to carry the part to be carried. A plurality of supporting structures are arranged on the bottom plate, and the plurality of supporting structures are arranged one by one corresponding to the plurality of bearing recesses. Among them, the supporting structure has an initial position and a supporting position, and when the supporting structure is in the initial position, the supporting structure has a preset distance with the part to be carried. When the supporting structure is in the supporting position, the supporting structure abuts against the bottom of the part to be carried away from the bearing recess to support the part to be carried. In this way, when the staff places the solar cell on the bearing device, the supporting structure is in the initial position, which is convenient for the staff to easily and accurately place the solar cell in the bearing recess, so that the bearing recess can perform preliminary positioning and carrying of the solar cell. Afterwards, the supporting structure is in the supporting position, supporting the portion of the solar cell away from the bearing recess, so that the solar cell is doubly supported, achieving uniformity and reliability of the bearing of the bearing device, avoiding the phenomenon of the solar cell being affected by its own gravity and causing the middle part to fall, adjusting the overall levelness of the solar cell, thereby reducing the warping of the solar cell during the heating and curing process, improving the production quality of the solar cell, and thus solving the problem of poor production quality of solar cells in the prior art.
