Description

Technical Field

[0001] The utility model relates to the technical field of heterojunction battery suckers, in particular to a sucker structure for reducing blockage of heterojunction batteries. Background Art

[0002] Heterojunction batteries are a popular battery technology at present. They have the advantages of high efficiency, low-temperature manufacturing process, no PID phenomenon, and can be developed into thin sheets. They have broad development prospects, but compared with other types of batteries, the automation structure is complex, resulting in more fragments. Therefore, reducing the equipment fragmentation rate has also become a top priority. At present, the suction cups used in the automated kicking mechanisms of various processes of heterojunctions are suction cups with relatively few holes. Some small fragments cannot be removed and will flow to the back and cause blockage of fragments, especially in the impurity suction process. Blockage will cause a large amount of fragments; this application is to modify the suction cup structure on the automated kicking mechanism and increase the suction cup holes, so as to achieve the purpose of sucking and kicking small fragments and reduce the blockage of fragments. Utility Model Content

[0003] In view of the shortcomings of the prior art mentioned above, the purpose of the utility model is to provide a suction cup structure for heterojunction batteries to reduce blockage, which is used to solve the problem that the suction cups used in the automated kicking mechanisms of various processes of heterojunction in the prior art are suction cups with relatively few holes, and some small fragments cannot be removed, and will flow to the back and cause blockage of the fragments, especially in the impurity suction process, blockage will cause a large number of fragments.

[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0005] A suction cup structure for reducing blockage in heterojunction batteries is used for removing debris from an automated kicking mechanism, comprising a suction cup seat and suction cup holes arranged on the suction cup seat, wherein the suction cup holes include a plurality of central suction cup holes arranged in the center of the suction cup seat and in a circular array, peripheral suction cup holes arranged circumferentially and symmetrically distributed around the central suction cup hole, end suction cup holes symmetrically arranged at both ends of the suction cup seat, and middle suction cup holes symmetrically arranged between the peripheral suction cup holes and the end suction cup holes.

[0006] To implement the above technical solution, the suction cups used in the automatic kicking mechanisms in various heterojunction processes currently have fewer suction cup holes, so some small fragments cannot be removed, and will flow into the back and cause blockage and fragments, especially in the impurity suction process, blockage will cause a large amount of fragments. The present application increases suction cup holes on the suction cup seat, and after the suction cup structure absorbs the battery cell, it is tested by AOI or PL. When fragments are detected, the automatic kicking mechanism will put the fragments into the defective box. The rational distribution of the suction cup holes allows smaller fragments to be removed, thereby greatly reducing the blockage and fragments.

[0007] In one embodiment of the present invention, the central suction cup hole and the peripheral suction cup holes have the same diameter, the central suction cup hole has a larger diameter than the end suction cup holes, and the end suction cup holes have a larger diameter than the middle suction cup hole.

[0008] To implement the above technical solution, the suction cup holes are rationally distributed so that the battery cell is evenly stressed during the adsorption process, thereby preventing the battery cell from being deformed or broken during the adsorption process.

[0009] In one embodiment of the present invention, the central suction cup hole, the peripheral suction cup holes, the end suction cup holes and the middle suction cup holes are all circular.

[0010] To implement the above technical solution, the larger the area of ​​the suction cup hole, the greater the suction force. In the present application, the suction cup hole is preferably circular for ease of processing. In addition, an elliptical or other shape may also be used.

[0011] In one embodiment of the present invention, the suction cup seat is rectangular.

[0012] To implement the above technical solution, since the battery cell is generally rectangular, in order to ensure that the battery cell is subjected to uniform force during the adsorption process, the suction cup structure also adopts a rectangular shape.

[0013] In an embodiment of the present invention, a plurality of the central suction cup holes form two concentric circles.

[0014] To implement the above technical solution, a plurality of central suction cups form two concentric circles, and the middle part of the battery cell will be more evenly stressed when the battery cell is adsorbed.

[0015] In one embodiment of the present invention, defective battery fragments are sucked into a defective box through AOI or PL inspection.

[0016] To implement the above technical solution, AOI or PL detection is provided in the battery kicking process. After the battery cells sucked up by the suction cup structure are inspected, the battery cells with fragments are sucked into the defective box to prevent the battery cells from flowing to the subsequent processes and causing blockage by fragments.

[0017] As described above, the utility model discloses a suction cup structure for reducing blockage of heterojunction batteries, which has the following beneficial effects: currently, the suction cups used in the automatic kicking mechanisms in various processes of heterojunction have fewer suction cup holes, so some small fragments cannot be removed, and flow into the back and cause blockage and debris, especially in the impurity suction process, blockage will cause a large amount of debris. The present application increases suction cup holes on the suction cup seat so that small fragments can be sucked up. After the suction cup structure sucks the battery cell, it is tested by AOI or PL. When debris is detected, the automatic kicking mechanism will put the fragments into the defective box. The rational distribution of the suction cup holes allows smaller fragments to be removed, thereby greatly reducing the blockage and debris. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1The utility model provides a suction cup structure for reducing blockage of heterojunction batteries, which is used for removing debris of an automated kicking mechanism, including a suction cup seat 1 and suction cup holes arranged on the suction cup seat 1, wherein the suction cup holes include a plurality of central suction cup holes 2 arranged in the center of the suction cup seat 1 and in a circular array, peripheral suction cup holes 3 arranged circumferentially and symmetrically distributed above the central suction cup holes 2, end suction cup holes 4 symmetrically arranged at both ends of the suction cup seat 1, and middle suction cup holes 5 symmetrically arranged between the peripheral suction cup holes 3 and the end suction cup holes 4.

[0024] At present, the suction cups used in the automatic kicking mechanisms in various heterojunction processes have fewer suction cup holes, so some small fragments cannot be removed and flow into the back, causing blockage and fragments. Especially in the impurity absorption process, blockage will cause a large amount of fragments. The present application increases suction cup holes on the suction cup seat 1. After the suction cup structure absorbs the battery cell, it is tested by AOI or PL. When fragments are detected, the automatic kicking mechanism will put the fragments into the defective box. The rational distribution of the suction cup holes allows smaller fragments to be removed, thereby greatly reducing the blockage and fragments.

[0025] The central suction cup hole 2 has the same diameter as the peripheral suction cup holes 3, the central suction cup hole 2 has a larger diameter than the end suction cup holes 4, and the end suction cup holes 4 have a larger diameter than the middle suction cup holes 5. By rationally distributing the suction cup holes, the battery cell is subjected to uniform force during the adsorption process, thereby preventing the battery cell from being deformed or broken during the adsorption process.

[0026] The central suction cup hole 2, the peripheral suction cup hole 3, the end suction cup hole 4 and the middle suction cup hole 5 are all circular. The larger the area of ​​the suction cup hole, the greater the suction force. In the present application, the suction cup hole is preferably circular for easy processing. In addition, an elliptical or other shape can also be used.

[0027] The suction cup seat 1 is rectangular. Since the battery cell is generally rectangular, in order to ensure that the battery cell is evenly stressed during the adsorption process, the suction cup structure is also rectangular.

[0028] A plurality of the central suction cup holes 2 form two concentric circles. By forming two concentric circles with a plurality of central suction cups, the middle part of the battery cell will be more evenly stressed when the battery cell is adsorbed.

[0029] The defective battery fragments are sucked into the defective box through AOI or PL inspection. In the battery kicking process, AOI or PL inspection is set. After the battery cells sucked by this suction cup structure are inspected, the battery cells with fragments are sucked into the defective box to prevent the flow to the subsequent process and cause the fragments to block the cells.

[0030] The present application adds suction cup holes on the suction cup seat 1. After the suction cup structure absorbs the battery cell, it is inspected by AOI or PL. When fragments are detected, the automatic kicking mechanism will put the fragments into a defective box. The rational distribution of the suction cup holes allows smaller fragments to be removed, thereby greatly reducing the situation of blockage and fragments.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
