[0040] In the description of this embodiment, unless otherwise specified, the term "plurality" refers to a quantity of two or more than two.

[0041] Embodiment 1

[0042] The present embodiment provides a solar cell unloading tool, which can reduce the manual actions of employees to organize solar cells, thereby reducing damage to the solar cells, improving work efficiency and saving costs.

[0043] like Figure 1-Figure 3 As shown, the solar cell blanking tooling mainly includes a base 100 and an organizing component 200. Among them, there are at least two organizing components 200, and each two organizing components 200 form a group and are relatively arranged on the base 100, and each group of organizing components 200 can organize the opposite side edges of the solar cell 10. Each organizing component 200 respectively includes a first connecting portion 210 and a second connecting portion 220 that are interconnected, and the first connecting portion 210 and the base 100 are adjustably connected along a first direction. At least two second connecting portions 220 and the base 100 are arranged to form an accommodating space for accommodating the solar cell 10, and the two second connecting portions 220 can respectively contact the opposite side edges of the solar cell 10. It should be noted that the first direction in this embodiment is Figure 1 The X-axis direction.

[0044] Based on the above design, in this embodiment, the first connection part 210 is provided to achieve a stable connection between the organizing component 200 and the base 100, and the second connection part 220 is provided to enable the robot to limit and organize the solar cell 10 during the process of unloading the solar cell 10, thereby avoiding the manual adjustment of the solar cell 10 by employees, reducing the occurrence of scratches, missing corners, fingerprints and other undesirable phenomena on the solar cell 10, saving time and effort, improving work efficiency and saving costs.

[0045] In order to improve the efficiency of the solar cell unloading tool in organizing the solar cells 10, the base 100 in the present embodiment can be tilted, and the tilt angle can be set to 10° to 30°, etc. In this way, during the unloading process of the robot, each solar cell 10 can slide toward a lower position of the base 100 under the action of gravity, thereby improving the efficiency of the organization of the solar cells 10 and saving time and effort.

[0046] It is understandable that at least one second connection portion 220 is provided at a lower position of the base 100 in this embodiment to limit and reorganize each fallen solar cell 10. In order to improve the reorganization efficiency, the operator can set different numbers of reorganization components 200 according to actual needs. For example, reorganization components 200 can be provided on all four sides of the base 100.

[0047] like Figure 3 As shown, in this embodiment, the second connection portion 220 includes an inclined portion 2202, and the angle between the inclined portion 2202 or the extension line of the inclined portion 2202 and the base 100 is greater than 90 degrees. Specifically, the inclined portion 2202 is inclined in a direction away from the base 100, which can increase the area of ​​the upper region of the accommodating space, prevent the solar cell 10 from sliding and falling outside the area of ​​the sorting component 200 or colliding with the edge of the sorting component 200 during the falling process, and is conducive to improving the flexibility of the robot to unload materials.

[0048] Exemplarily, the inclined portion 2202 may be configured to be in a straight line or an arc shape.

[0049] Furthermore, the second connection part 220 in this embodiment also includes a straight part 2201, and the inclined part 2202 is arc-shaped, one end of the straight part 2201 is connected to the first connection part 210, and the other end of the straight part 2201 is connected to the inclined part 2202; the inclined part 2202 is bent in a direction away from the accommodation space. The setting of the inclined part 2202 can improve the flexibility of the robot in unloading the solar cell 10. In other words, it can increase the area of ​​the upper region of the accommodation space, which is more conducive to the robot unloading the solar cell 10 and avoids the interference between the solar cell 10 and the second connection part 220.

[0050] Optionally, in this embodiment, the first connection portion 210 and the second connection portion 220 are integrally formed, and the straight portion 2201 and the inclined portion 2202 of the second connection portion 220 are also integrally formed, thereby improving the processing efficiency of the integration component 200 and saving costs.

[0051] In this embodiment, there is no limitation on the curvature of the inclined portion 2202, and operators can flexibly set it according to actual needs.

[0052] Optionally, the base 100 in this embodiment is made of aluminum alloy, and the first connecting portion 210 and the second connecting portion 220 are both made of polyamide.

[0053] like Figure 3 As shown, in this embodiment, a sliding layer 230 is provided on the side of the second connection portion 220 facing the accommodating space, and the sliding layer 230 is configured to reduce the friction between the second connection portion 220 and the falling solar cell 10, so that the solar cell 10 can fall more smoothly and avoid edge collapse or scratches. Furthermore, a buffer layer 240 is also provided between the second connection portion 220 and the sliding layer 230, and the buffer layer 240 is configured to buffer the falling solar cell 10 in the first direction, reducing or even avoiding undesirable phenomena such as cracks and missing corners caused by the solar cell 10 falling.

[0054] For example, the sliding layer 230 in this embodiment can be set as a polyethylene member, for example, the sliding layer 230 is made of 3M5423 ultra-high molecular polyethylene material with high temperature resistance and wear resistance. And the sliding layer 230 can be set as a layer, and the sliding layer 230 covers the entire second connecting portion 220. The size of the sliding layer 230 can be set to a length of 8 cm, a width of 2 cm, a thickness of 0.3 mm, and the like.

[0055] Illustratively, the buffer layer 240 in this embodiment is a foam piece, that is, it is made of foam material to save costs.

[0056] In some optional embodiments, two sides of the buffer layer 240 are respectively bonded to the second connection portion 220 and the sliding layer 230 , which saves time and effort and improves the reliability and stability of the solar cell blanking tooling.

[0057] The solar cell blanking tool in this embodiment further includes a first fixing member (not shown in the figure), such as Figure 3 As shown, a mounting hole 2203 is opened on the second connecting part 220, and the first fixing member is passed through the mounting hole 2203 and fixes the buffer layer 240 on the second connecting part 220, and the side of the buffer layer 240 away from the second connecting part 220 is bonded to the sliding layer 230.

[0058] Optionally, the first fixing member can be configured as a component with a locking function such as a screw or a clip. The setting of the first fixing member can realize the fixation and later disassembly of the buffer layer 240. When the buffer layer 240 and the sliding layer 230 need to be replaced later, the operator can easily remove the first fixing member, thereby realizing the replacement of the buffer layer 240 and the sliding layer 230, saving costs.

[0059] like Figure 1-Figure 2 As shown, in this embodiment, the solar cell blanking tool also includes a second fixing member 300, a strip hole 2101 is opened on the first connecting portion 210, and the second fixing member 300 is passed through the strip hole 2101 to fix the first connecting portion 210 on the base 100 in an adjustable position along the first direction.

[0060] By providing the second fixing member 300 and the strip-shaped hole 2101 , the solar cell blanking tool can be suitable for blanking solar cells 10 of different sizes and types, thereby improving the flexibility and applicability of the solar cell blanking tool and saving costs.

[0061] Optionally, the second fixing member 300 may be configured as a screw, a bolt or other components.

[0062] Optionally, the organizing component 200 in this embodiment has a structure that is wide at the top and narrow at the bottom, thereby achieving the purpose of saving consumables and saving costs.

[0063] This embodiment also provides a solar cell processing device, which includes a manipulator and the above-mentioned solar cell unloading tooling, and the manipulator can place the solar cell 10 on the solar cell unloading tooling. The solar cell processing device can reduce damage to the solar cell 10, improve operating efficiency, and save costs.

[0064] Exemplarily, the solar cell processing equipment includes but is not limited to a dicing machine.

[0065] Embodiment 2

[0066] like Figure 1-Figure 2 As shown, this embodiment provides a solar cell unloading tool, and the main difference from the first embodiment is that the solar cell unloading tool includes a tilted pad block 400, which is arranged on the base 100, and the tilted pad block 400 is located in the accommodating space, and the second connecting portion 220 is located at the side of the tilted pad block 400, and the tilted pad block 400 is used to place the solar cell 10 and can make the solar cell 10 slide along the tilt direction of the tilted pad block 400, so that the tilted pad block 400 can adjust the other side of the solar cell 10.

[0067] The tilt angle of the tilt pad 400 can be set to 10° to 30°, so that during the unloading process of the robot, each solar cell 10 can slide down in the tilt direction of the tilt pad 400 under the action of gravity, thereby improving the efficiency of arranging the solar cells 10 and saving time and effort. Furthermore, a plurality of second connecting parts 220 can be set around the tilt pad 400 in this embodiment, or the second connecting parts 220 can be set only on the opposite sides of the tilt pad 400 and at a lower position of the tilt pad 400 along the tilt direction.

[0068] Specifically, the inclined pad 400 in this embodiment has an inclined surface and a blocking surface. The inclined surface is inclined toward the blocking surface. The inclined surface is used to place the solar cell 10, and the blocking surface is used to block one side of the solar cell 10. In this way, when the robot arm is unloading the solar cell 10, the solar cell 10 can slide along the inclined direction of the inclined surface and then be blocked by the blocking surface, thereby achieving the effect of arranging the other side of the solar cell 10.

[0069] The remaining structures of the solar cell blanking tool in this embodiment are the same as those in the first embodiment, and will not be described in detail here.

[0070] Obviously, the above are only preferred embodiments of the present invention and the technical principles used.
