[0035] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0036] It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof in subsequent figures is not necessary.

[0037] First, the feeding mechanism 100 according to an embodiment of the present invention will be specifically described with reference to the accompanying drawings.

[0038] As Figures 1 to 5 shown, the feeding mechanism 100 according to an embodiment of the present invention includes: a base 10, a suction member 20, and a blowing assembly 30.

[0039] Specifically, a receiving space 11 adapted to accommodate sheets and protective sheets stacked in a staggered manner along a first direction is defined on the base 10. The suction member 20 is movably disposed on the base 10 along the first direction and is located on the top side of the receiving space 11, and the suction member 20 is used for sucking the sheets or the protective sheets. The blowing assembly 30 is disposed on the base 10. The blowing assembly 30 includes a first blowing member and a second blowing member. The second blowing member 33 is located on the side of the first blowing member 35 close to the suction member 20. A first air outlet 31 is provided on the surface of the first blowing member facing the receiving space 11. The second blowing member extends along a second direction, the second direction is perpendicular to the first direction, and at least one second air outlet 32 is provided on the second blowing member.

[0040] In other words, the feeding mechanism 100 according to an embodiment of the present invention is mainly composed of a base 10, a suction member 20, and a blowing assembly 30. The base 10 can serve as a carrier. A receiving space 11 can be provided on the base 10, and sheets can be accommodated in the receiving space 11. The sheets can be composed of sheets and protective sheets stacked in a staggered manner along a first direction. Optionally, the sheets can be photovoltaic cell sheets, the protective sheets can be paper sheets, and paper sheets can be interposed between adjacent two photovoltaic cell sheets to protect the surfaces of the photovoltaic cell sheets.

[0041] The adsorbing member 20 can move relative to the machine base 10 in a first direction, and the adsorbing member 20 can adsorb the material sheet or the protective sheet. During the feeding process of the feeding mechanism 100, since the material sheets and the protective sheets are arranged in an interleaved and stacked manner, the adsorbing member 20 needs to successively adsorb the material sheets and the protective sheets, convey the material sheets to the next station, and convey the protective sheets to the centralized storage location. Optionally, the adsorbing member 20 can include a suction cup. The first direction can be the vertical direction.

[0042] In addition, a blowing assembly 30 can be connected to the machine base 10. The blowing assembly 30 can mainly be composed of a first blowing member 35 and a second blowing member 33. The first blowing member 35 has a first blowing port 31, and the second blowing member 33 has a second blowing port 32. The number of the first blowing port 31 and the second blowing port 32 is not limited herein. The first blowing port 31 and the second blowing port 32 can be respectively connected to a blower and can respectively control the blowing of the first blowing port 31 and the second blowing port 32.

[0043] Among them, the first blowing port 31 can be arranged on the side of the accommodating space 11 and can blow air toward the side of the material sheet. The side of the material sheet can be one side or multiple sides of the material sheet in the horizontal direction, that is, any one side or multiple sides of the material sheet except its own top side and bottom side. The air flow blown out by the first blowing port 31 can flow substantially in the horizontal direction. That is to say, the air flow blown out by the first blowing port 31 can be parallel to the material sheet and the protective sheet, so as to be able to blow into the space between the material sheet and the protective sheet, enabling the stacked material sheets and protective sheets to be separated, especially one or more sheets at the topmost layer.

[0044] A second blowing member 33 can be connected to the machine base 10. The connection between the second blowing member 33 and the machine base 10 can include but is not limited to direct connection, indirect connection, fixed connection, and detachable connection.

[0045] In addition, the extending direction of the second blowing member 33 can be perpendicular to the moving direction of the adsorbing member 20. For example, the adsorbing member 20 moves in the vertical direction, and the second blowing member 33 extends in the horizontal direction. Photovoltaic cells are usually square, and the axis of the second blowing member 33 can be parallel to one edge of the photovoltaic cell.

[0046] A blowing channel can be provided in the second blowing member 33, and the blowing channel can be communicated with a blower. One or more second blowing ports 32 can be provided on the surface of the second blowing member 33, and the second blowing ports 32 can be communicated with the blowing channel.

[0047] In addition, the second blowing member 33 is located on the side of the first blowing member 35 close to the adsorbing member 20, which can make the second blowing port 32 closer to the adsorbing member 20. For example, the height of the second blowing port 32 is higher than the height of the first blowing port 31. Therefore, the second blowing port 32 can blow air to the topmost material sheet and protective sheet adsorbed by the adsorbing member 20.

[0048] The second air outlet 32 is arranged on the second air blowing member 33, and the orientation of the second air blowing member 33 can be adjusted by adjusting the attitude of the second air blowing member 33. After adjusting to a suitable attitude, the second air blowing member 33 is fixed to the machine base 10, so that it can be adjusted according to different requirements, which is beneficial to improving the applicability of the loading mechanism 100. In addition, the second air blowing member 33 also has the advantages of simple structure, easy manufacturing, small occupied space and convenient installation.

[0049] During the lifting process of the adsorbing member 20, the protective sheet may be adsorbed on the surface of the sheet due to static electricity.

[0050] When the adsorbing member 20 picks up the sheet, although the protective sheet will be misaligned with the sheet under the action of the air flow blown out by the first air outlet 31, it is difficult for the side air flow blown out by the first air outlet 31 to enter between the sheet and the protective sheet, while the air flow blown out by the second air outlet 32 can blow off the protective sheet along the gap.

[0051] When the adsorbing member 20 picks up the protective sheet, since the sheet is harder and the protective sheet is softer, the inclined air flow blown out by the second air outlet 32 can deform the protective sheet, so that the adhered sheet drops off.

[0052] The working process of the loading mechanism 100 of this embodiment will be described in detail below.

[0053] When the adsorbing member 20 does not pick up the sheet, the first air outlet 31 can blow a gentle breeze continuously to disperse the sheet and the protective sheet in advance. When the adsorbing member 20 picks up the sheet, during the process of the adsorbing member 20 descending and lifting, the first air outlet 31 on the side strengthens the blowing to make the sheet and the protective sheet separate as much as possible. When the adsorbing member 20 picks up the sheet and lifts to a predetermined height until before the adsorbing member 20 performs lateral movement and transportation, the first air outlet 31 on the side stops blowing, and at the same time the second air outlet 32 is opened to blow, so as to blow off the adhered protective sheet or sheet, thus solving the problem of sheet / paper sticking in the loading process.

[0054] Therefore, according to the loading mechanism 100 of the embodiment of the present invention, the first air outlet 31 and the second air outlet 32 are arranged in sequence from low to high on the side of the accommodation space 11. The wind blown out by the first air outlet 31 is used to disperse the sheet and the protective sheet in advance, and the adhered sheet and protective sheet are blown off by the second air outlet 32 when the adsorbing member 20 picks up the sheet and lifts. This effectively reduces the situation of the protective sheet sticking when picking up the sheet or the sheet sticking when picking up the protective sheet, solves the problem of sheet / paper sticking during the loading of photovoltaic cells, avoids equipment shutdown and alarm, reduces the manual processing time, and is beneficial to improving the production capacity.

[0055] According to an embodiment of the present invention, the axis of the second air outlet extends obliquely towards the machine base.

[0056] Specifically, the axis of the second air outlet 32 can be inclined relative to the first direction. For example, it can be arranged to face obliquely downward, so that the second air outlet 32 can blow air from the upper oblique direction. The included angle between the blowing direction of the second air outlet 32 and the blowing direction of the first air outlet 31 can be an acute angle.

[0057] Therefore, the force of the airflow blown out by the second air outlet 32 acting on the adhered sheet and the protective sheet can be inclined towards the machine base, prompting the separation of the sheet and the protective sheet, and more effectively solving the problem of sheet / tape carrying during the feeding of photovoltaic cells.

[0058] According to some other embodiments of the present invention, a plurality of second air outlets 32 arranged at intervals along the second direction are provided on the second blowing member 33. Thus, multiple airflows blown out from the plurality of second air outlets 32 can blow towards the sheet and the protective sheet along the inclined direction together, which is beneficial to improving the intensity of the airflow. At the same time, the multiple airflows blown out can converge to form a turbulent flow, which is beneficial to the separation of the adhered sheet and the protective sheet, and further reduces the problem of sheet / tape carrying.

[0059] In some specific embodiments of the present invention, the second blowing member 33 and the first air outlet 31 are located on the same side of the accommodation space 11.

[0060] Specifically, since the first air outlet 31 can disperse the sheet and the protective sheet in advance, a dislocation or gap can be formed at one end of the sheet and the protective sheet close to the first air outlet 31. Arranging the second blowing member 33 on the same side as the first air outlet 31 is beneficial for the second air outlet 32 to blow off the adhered sheet and the protective sheet through the formed dislocation or gap, and more effectively avoids the occurrence of adhesive picking.

[0061] According to some alternative embodiments of the present invention, at least two second blowing members 33 are spaced apart along the third direction on both sides of the accommodation space 11, and the third direction is perpendicular to the first direction and the second direction respectively.

[0062] Specifically, as Figure 2 shown, in the third direction, the two second blowing members 33 can be spaced apart, and the accommodation space 11 can be located between the two second blowing members 33. That is to say, the second air outlets 32 on the two second blowing members 33 can blow air obliquely on the attracted member attracted by the suction member 20 from both sides of the accommodation space 11 respectively. Therefore, when the attracted member includes an adhered sheet and a protective sheet, the blowing assembly 30 can separate the two from both ends of the sheet and the protective sheet respectively. On the one hand, the reliability of the separation can be improved, and on the other hand, it is beneficial to improve the separation efficiency.

[0063] In some other embodiments, the number of the second blowing members 33 can be greater than two, and a plurality of second blowing members 33 can be arranged on one side of the accommodation space 11 to further improve the reliability of the separation.

[0064] According to some other embodiments of the present utility model, the blowing assembly 30 further includes an adjusting bracket 34. The adjusting bracket 34 is disposed on the machine base 10, and the second blowing member 33 is connected to the adjusting bracket 34. The adjusting bracket 34 is used to adjust the height and tilt angle of the second blowing port 32.

[0065] Specifically, an adjusting bracket 34 can be connected to the machine base 10, and the height of the adjusting bracket 34 is adjustable relative to the machine base 10. For example, the adjusting bracket 34 is detachably connected to the machine base 10, and the adjusting bracket 34 can be provided with a plurality of mounting points extending in the first direction. By adjusting the mounting points of the connection between the adjusting bracket 34 and the machine base 10, the height of the adjusting bracket 34 can be changed, thereby changing the height of the second blowing member 33 on the adjusting bracket 34.

[0066] In addition, the tilt angle of the second blowing port 32 on the second blowing member 33 can also be adjusted by the adjusting bracket 34. For example, the second blowing member 33 is rotatable about its own axis relative to the adjusting bracket 34, thereby changing the tilt angle of the second blowing port 32. After the attitude adjustment of the second blowing member 33 is completed, the adjusting bracket 34 can lock the second blowing member 33.

[0067] In this embodiment, the adjusting bracket 34 can be used to adjust the height and tilt angle of the second blowing port 32, so that the feeding mechanism 100 can be adjusted according to different requirements, which is beneficial to improving the applicability.

[0068] In some specific embodiments of the present utility model, the feeding mechanism 100 further includes a first detector 40, a second detector 50, and a controller (not shown in the figure). The first detector 40 and the second detector 50 are spaced apart along the first direction and are respectively connected to the machine base 10. The first detector 40 is used to detect the first side surface of the object to be adsorbed adsorbed by the adsorbing member 20, and the second detector 50 is used to detect the second side surface of the object to be adsorbed adsorbed by the adsorbing member 20. The controller is electrically connected to the first detector 40 and the second detector 50 respectively, and is used to control the adsorbing member 20 to convey the object to be adsorbed to the next working station or drop it back into the accommodating space 11 according to the detection results.

[0069] Specifically, as Figure 3 shown, the first detector 40 and the second detector 50 can be arranged at intervals along the first direction, wherein the position of the first detector 40 is higher and the position of the second detector 50 is lower. After the adsorbing member 20 picks up the material, the first detector 40 can detect the top surface of the object to be adsorbed, and the second detector 50 can detect the bottom surface of the object to be adsorbed.

[0070] The detected factors may include, but are not limited to, color. For example, if the material sheet and the protective sheet have different colors, the first detector 40 and the second detector 50 can be used to detect the colors of the top and bottom surfaces of the adsorbed object to determine whether adhesion occurs.

[0071] When the detection results of the first detector 40 and the second detector 50 are the same, for example, the same color is detected, it can be determined that no adhesion has occurred, and the controller can control the adsorbed object 20 to continue horizontal movement and handling.

[0072] When the detection results of the first detector 40 and the second detector 50 are different, for example, different colors are detected, it can be determined that adhesion has occurred, and the controller can control the adsorbed object 20 to release the adsorbed object, so that the adhered material sheet and the protective sheet fall back into the accommodation space 11, and the material taking is performed again.

[0073] Optionally, both the first detector 40 and the second detector 50 can be photoelectric sensors.

[0074] In this embodiment, the first detector 40 and the second detector 50 can be used to detect the result of material taking. When striping / papering occurs, the controller can control the adsorbed object 20 to take the material again, realizing material taking feedback and reasonably processing the feedback. With the airflow of the first air outlet 31 and the second air outlet 32, the equipment alarm rate is greatly reduced, the manual processing time is reduced, which is beneficial to improving the equipment production capacity.

[0075] According to some optional embodiments of the present invention, the adsorbed object 20 is movable between a first state and a second state along a first direction. When the adsorbed object 20 is in the first state, the height of the adsorbed object 20 is h1, and the adsorbed object 20 is in contact with the topmost material sheet or protective sheet in the accommodation space 11. When the adsorbed object 20 is in the second state, the height of the adsorbed object 20 is h2, h2 > h1, and the first detector 40 is higher than the adsorbed object 20, and the second detector 50 is lower than the adsorbed object 20.

[0076] Specifically, the first state of the adsorbed object 20 can be the state when the adsorbed object 20 falls to contact the topmost material sheet, and the second state of the adsorbed object 20 can be the state when the adsorbed object 20 takes the material and is lifted by a preset distance. The first detector 40 and the second detector 50 can detect the adsorbed object after the adsorbed object 20 takes the material and is lifted by a preset distance, thus realizing material taking feedback, and then the controller controls the adsorbed object 20 to perform the next action according to the feedback, which can avoid the problem of striping / papering.

[0077] According to other some embodiments of the present invention, as Figure 5 shown, the first air outlet 31 extends along the first direction, so that the airflow blown out by the first air outlet 31 can cover multiple material sheets and multiple protective sheets, which is beneficial to the separation of the material sheet and the protective sheet.

[0078] In addition, the first air outlet 31 can be a long and narrow slit. Thus, when the air flow flows out of the first air outlet 31, the flow rate is faster, which is more conducive to separating the material sheet and the protective sheet.

[0079] In some specific embodiments of the present utility model, at least two first air outlets 31 are spaced apart in the third direction on both sides of the accommodation space 11.

[0080] Specifically, as Figure 2 shown, in the third direction, the two first air outlets 31 can be arranged at intervals, and the accommodation space 11 can be located between the two first air outlets 31. That is to say, the two first air outlets 31 can blow air on the material sheet from both sides of the accommodation space 11 respectively. Therefore, the blowing assembly 30 can separate the overlapping material sheets and protective sheets from both ends respectively. On the one hand, the reliability of separation can be improved, and on the other hand, it is beneficial to improve the separation efficiency.

[0081] In some other embodiments, the number of the first air outlets 31 can be more than two, and multiple first air outlets 31 can be arranged on one side of the accommodation space 11 to further improve the reliability of separation.

[0082] In some specific embodiments, the first blowing member 35 can be a blowing block. An air duct can be provided in the blowing block, and a first air outlet 31 can be provided on the surface of the blowing block facing the accommodation space 11. The first air outlet 31 is connected to the air blower through the air duct.

[0083] The embodiment of the present utility model also provides a photovoltaic cell production device, which includes the feeding mechanism 100 according to any one of the above embodiments. Since the feeding mechanism 100 according to the embodiment of the present utility model has the above technical effects, therefore, the photovoltaic cell production device according to the embodiment of the present utility model also has corresponding technical effects, that is, effectively reducing the situation of sticking to the protective sheet when taking the material sheet or sticking to the material sheet when taking the protective sheet, solving the problem of taking the sheet / paper when feeding the photovoltaic cell, avoiding the equipment from stopping and alarming, reducing the manual processing time, and being beneficial to improving the production capacity.

[0084] In the actual application process, the above controller is not limited to a certain brand and model. The present utility model does not need to make an explanation for this. It should be noted that the computer program loaded by the above controller is not within the protection scope of the present utility model.
