Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic production equipment, in particular to a feeding production line. Background Art

[0002] At present, for short silicon rods, short rods need to be spliced ​​together to form a fixed-length bonding rod. Before bonding these short rods, in order to improve the bonding accuracy, the splicing seam needs to be precisely controlled by a rod splicing device to ensure the bonding effect.

[0003] However, when conveying multiple silicon rods, the silicon rods are prone to move on the conveyor line, causing each silicon rod to be skewed to varying degrees. Thus, when the robot simultaneously clamps multiple silicon rods, the robot is often unable to clamp them in place due to the skewness of the silicon rods, causing the silicon rods to fall easily, affecting the normal operation of the machine, and thus causing production safety failures.

[0063] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0064] like Figures 1 to 9As shown, an embodiment of the utility model provides a feeding production line, which includes a first conveying mechanism 10, a positioning mechanism 20 and a first transfer mechanism 30. The conveying part of the first conveying mechanism 10 can be movably arranged to transport at least two silicon rods. The positioning mechanism 20 is arranged at the unloading end of the first conveying mechanism 10. The positioning mechanism 20 has a first positioning structure 21 and a second positioning structure 22 that are arranged at intervals. At least one of the first positioning structure 21 and the second positioning structure 22 is arranged close to or far away from the other of the first positioning structure 21 and the second positioning structure 22 to clamp and position at least two silicon rods. The transfer part 31 of the first transfer mechanism 30 is movably arranged, and the transfer part 31 has a material picking position and a transfer position; when the transfer part 31 is in the material picking position, the transfer part 31 is arranged relative to the positioning space between the first positioning structure 21 and the second positioning structure 22 to clamp at least two silicon rods located in the positioning space; when the transfer part 31 is in the transfer position, the transfer part 31 drives at least two silicon rods to transfer to the first predetermined position.

[0065] The feeding production line provided by the embodiment of the utility model can clamp and position at least two silicon rods transported from the first conveying mechanism 10 to the unloading end through the setting of the positioning mechanism 20, thereby ensuring that the silicon rods are placed in the same direction, and at least two silicon rods that have been positioned on the positioning mechanism are transferred at the same time through the transfer part 31 of the first transfer mechanism 30, so as to carry out subsequent processes, effectively ensuring that the transfer part 31 of the first transfer mechanism 30 can stably drive the transfer of at least two silicon rods, and will not be unable to drive the transfer or fall during the transfer process due to the skewness of the silicon rods during transportation. Therefore, the feeding production line provided by this embodiment can solve the technical problem of poor transfer stability of silicon rods in the process of automatic splicing of silicon rods in the prior art.

[0066] Specifically, the first conveying mechanism 10 includes a first supporting seat, and the conveying part is movably disposed on the first supporting seat.

[0067] Specifically, the first transfer mechanism 30 includes a first base 32 and a first mechanical arm 33, the first mechanical arm 33 is rotatably arranged relative to the first base 32, and the transfer part 31 is rotatably arranged on the first mechanical arm 33. With such a structural arrangement, the relative position relationship between the transfer part 31 and at least two silicon rods can be adjusted by rotating the first mechanical arm 33 and the transfer part 31, so that the extension direction of the transfer part 31 is consistent with the extension direction of at least two silicon rods, and the stable transfer of the silicon rods is effectively ensured.

[0068] Specifically, the first predetermined position is set on the seam mechanism 40 , and when the transfer part 31 is at the transfer position, the transfer part 31 drives at least two silicon rods to be transferred to the seam mechanism 40 .

[0069] Specifically, the positioning mechanism 20 spans across or is embedded in the first conveying mechanism 10 .

[0070] Specifically, the positioning mechanism 20 also includes an end face pushing structure 23, which is movably arranged at the ends of the first positioning structure 21 and the second positioning structure 22, and the end face pushing structure 23 has a positioning position and an avoidance position. When the end face pushing structure 23 is in the positioning position, at least part of the end face pushing structure 23 abuts against one end of a combination body composed of at least two silicon rods; when the end face pushing structure 23 is in the avoidance position, the end face pushing structure 23 avoids the positioning space setting. With such a structural setting, the silicon rod can be abutted and pushed by the end face pushing structure 23, ensuring that the silicon rod is within a safe range that is easy to clamp, ensuring the consistency of the position before each silicon rod loading, thereby ensuring that the transfer part 31 of the first transfer mechanism 30 can stably grasp and transfer the silicon rod.

[0071] Specifically, the positioning mechanism 20 further includes a lifting structure 24, which is drivingly connected to the end surface pushing structure 23, so that the end surface pushing structure 23 moves closer to or farther away from the first conveying mechanism 10. In this way, the end surface pushing structure 23 can avoid the positioning space, thereby ensuring that the silicon rods can enter the positioning space.

[0072] Specifically, at least one of the first positioning structure 21 and the second positioning structure 22 includes a positioning plate and a positioning portion, and the positioning plate can be movably arranged. The positioning portion is arranged on the positioning plate, and the outer peripheral surface of the positioning portion is an arc surface, and at least part of the outer peripheral surface of the positioning portion protrudes from the end surface of the positioning plate. Among them, the positioning plate extends along a preset direction, and there are multiple positioning portions, and the multiple positioning portions are arranged on the positioning plate at intervals along the preset direction. With such a structural arrangement, at least one of the first positioning structure 21 and the second positioning structure 22 can be driven by the positioning plate to move closer to or away from the other of the first positioning structure 21 and the second positioning structure 22. At the same time, the arrangement of the positioning portion can reduce the contact area with the silicon rod, reduce the possibility of damaging the surface of the silicon rod during the positioning process, and effectively protect the silicon rod.

[0073] Specifically, the first positioning structure 21 includes a first positioning plate 211 and a first positioning portion 212, and the first positioning plate 211 is movably arranged. The first positioning portion 212 is arranged on the first positioning plate 211, and the outer peripheral surface of the first positioning portion 212 is an arc surface, and at least part of the outer peripheral surface of the first positioning portion 212 protrudes from the end surface of the first positioning plate 211. Among them, the first positioning plate 211 extends along a preset direction, and there are multiple first positioning portions 212, and multiple first positioning portions 212 are arranged on the first positioning plate 211 at intervals along the preset direction. With such a structural arrangement, the first positioning plate 211 can drive the first positioning structure 21 to move closer to or away from the second positioning structure 22. At the same time, the arrangement of the first positioning portion 212 can reduce the contact area with the silicon rod, reduce the possibility of damaging the surface of the silicon rod during the positioning process, and effectively protect the silicon rod.

[0074] Specifically, the second positioning structure 22 includes a second positioning plate and a second positioning portion 221, and the second positioning plate can be movably arranged. The second positioning portion 221 is arranged on the second positioning plate, and the outer peripheral surface of the second positioning portion 221 is an arc surface, and at least part of the outer peripheral surface of the second positioning portion 221 protrudes from the end surface of the second positioning plate. Among them, the second positioning plate extends along a preset direction, and there are multiple second positioning portions 221, and multiple second positioning portions 221 are arranged on the second positioning plate at intervals along the preset direction. With such a structural arrangement, the second positioning plate can drive the second positioning structure 22 to move closer to or away from the first positioning structure 21. At the same time, the arrangement of the second positioning portion 221 can reduce the contact area with the silicon rod, reduce the possibility of damaging the surface of the silicon rod during the positioning process, and effectively protect the silicon rod.

[0075] Specifically, the positioning part is rotatably arranged on the positioning plate. In this way, the friction between the silicon rod and the positioning part can be reduced, and when the silicon rod is pushed by the end surface pushing structure 23, the clamping and positioning of the silicon rod by the first positioning structure 21 and the second positioning structure 22 will not affect the smooth pushing of the end surface pushing structure 23, and can also effectively protect the surface of the silicon rod from damage.

[0076] Specifically, the pushing portion of the end surface pushing structure 23 forms at least a part of the end surface pushing structure 23, and the pushing portion is made of plastic. In this way, the silicon rod can be effectively protected and the surface of the silicon rod is not easily damaged when pushing.

[0077] Specifically, the end surface pushing structure 23 includes a pushing plate 231 and a pushing block 232. The pushing block 232 forms a pushing portion. The pushing block 232 is protruding from the pushing plate 231. There are multiple pushing blocks 232, and the multiple pushing blocks 232 are spaced apart on the pushing plate 231. In this way, the silicon rod can be evenly stressed by the abutment of the multiple pushing blocks 232 against the silicon rod, and the silicon rod can be pushed stably.

[0078] Specifically, the end surface pushing structure 23 also includes an end surface driving member 233, which is drivingly connected to the pushing plate 231, so that the end surface pushing structure 23 can move in a direction close to or away from the positioning space. In this way, it is convenient to make the end surface pushing structure 23 avoid the positioning space, thereby ensuring that the silicon rod can enter the positioning space.

[0079] Specifically, the first positioning structure 21 has a first positioning portion 212 for contacting at least two silicon rods, and the first positioning portion 212 is made of plastic. In this way, the silicon rods can be effectively protected and the surfaces of the silicon rods are not easily damaged during positioning.

[0080] Specifically, the second positioning structure 22 has a second positioning portion 221 for contacting at least two silicon rods, and the second positioning portion 221 is made of plastic. In this way, the silicon rods can be effectively protected and the surfaces of the silicon rods are not easily damaged during positioning.

[0081] Specifically, the pusher, the first positioning portion 212 and the second positioning portion 221 are all made of ultra-high molecular weight polyethylene material, so that the silicon rod can be effectively protected and the surface of the silicon rod is not easily damaged when being pushed.

[0082] Specifically, the positioning mechanism 20 further includes a position detection member, the detection head of which is disposed toward the positioning space or in the positioning space. In this way, the position detection member can detect whether there is a silicon rod in the positioning space, and can also detect whether the position of the silicon rod is within a safe range, thereby facilitating the control of the operation of the first transfer mechanism 30.

[0083] In order to more conveniently control the opening and closing of the detection, the positioning mechanism 20 is provided with a material presence switch, a machine type detection switch and an over-limit switch.

[0084] In this embodiment, the feeding production line further includes a seam mechanism 40, a cleaning mechanism 60 and a second transfer mechanism 50. The seam mechanism 40 has a seam space for splicing silicon rods. The cleaning mechanism 60 is used to wipe the silicon rods. The transfer part of the second transfer mechanism 50 is movably arranged, and the second transfer mechanism 50 has a first working position, a second working position and a third working position; when the second transfer mechanism 50 is in the first working position, the transfer part of the second transfer mechanism 50 is arranged opposite to the seam space to clamp the spliced ​​silicon rods; when the second transfer mechanism 50 is in the second working position, the transfer part of the second transfer mechanism 50 drives the spliced ​​silicon rods to transfer to the second predetermined position; when the second transfer mechanism 50 is in the third working position, the transfer part of the second transfer mechanism 50 is arranged opposite to the cleaning mechanism 60 to clean the silicon rods on the second transfer mechanism 50. With such a structural arrangement, the grabbing, cleaning and feeding of the spliced ​​silicon rods can be controlled by the second transfer mechanism 50. When the silicon rods are spliced, the second transfer mechanism 50 moves to the first working position to grab the silicon rods. Then the second transfer mechanism 50 drives the silicon rods to move to the third working position to clean the silicon rods. After cleaning, the second transfer mechanism 50 moves to the second working position to load the spliced ​​silicon rods. The overall process can be automated through the second transfer mechanism 50, which effectively improves the loading efficiency and the degree of automation.

[0085] Specifically, the stitching mechanism 40 includes a frame 41, a tail end positioning structure 42, a splicing rod structure 43, an end face distance measurement structure 44 and a visual detection structure 45, and the tail end positioning structure 42, the splicing rod structure 43, the end face distance measurement structure 44 and the visual detection structure 45 are all arranged on the frame 41.

The splicing rod structure 43 is movably arranged on the frame 41 along the extension direction of the stitching space, and the visual detection structure 45 is movably arranged on the frame 41 along the extension direction of the stitching space. With such a structural arrangement, after the first transfer mechanism 30 places the silicon rod on the splicing mechanism 40, the silicon rod can be positioned by the tail end positioning structure 42, and the splicing of the silicon rod can be achieved through the cooperation of the splicing rod structure 43 and the visual detection structure 45. The end face ranging structure 44 detects and feeds back the position of the end face of the silicon rod, which facilitates the second transfer mechanism 50 to grab the spliced ​​silicon rod.

The spraying part 62 and the wiping part 63 are arranged on the loading part 61, and the spraying part 62 is arranged on one side of the wiping part 63. With such a structural arrangement, other structural components of the cleaning mechanism 60 can be supported and fixed by the loading part 61, and related cleaning supplies can be stored at the same time. The cleaning agent is sprayed on the silicon rod by the spraying part 62, and then the silicon rod is wiped and cleaned by the wiping part 63.

[0087] Specifically, the second transfer mechanism 50 includes a second base and a second mechanical arm, the second mechanical arm is rotatably arranged relative to the second base, and the transfer part of the second transfer mechanism 50 is rotatably arranged on the second mechanical arm. With such a structural arrangement, the relative position relationship between the transfer part of the second transfer mechanism 50 and the silicon rod can be adjusted by the rotation of the second mechanical arm and the transfer part of the second transfer mechanism 50, so that the extension direction of the transfer part of the second transfer mechanism 50 is consistent with the extension direction of the silicon rod, and the stable transfer of the silicon rod is effectively ensured.

[0088] Specifically, the stitching mechanism 40 and the cleaning mechanism 60 are respectively arranged on both sides of the second transfer mechanism 50. The feeding production line also includes a second conveying mechanism 70, and the conveying part of the second conveying mechanism 70 is movably arranged to convey the positioning tool 80. The second conveying mechanism 70 is arranged between the stitching mechanism 40 and the second transfer mechanism 50.

[0089] Specifically, the second conveying mechanism 70 is disposed between the cleaning mechanism 60 and the second transfer mechanism 50. In this way, the second transfer mechanism 50 can be conveniently docked with the cleaning mechanism 60 and the second conveying mechanism 70 respectively.

[0090] Specifically, the positioning tool 80 is used to clamp and position the silicon rods after splicing. The positioning tool 80 includes a main body 81, a silicon rod clamping part 82 and a resin plate clamping part 83.

The positioning tool 80 also includes a tool guide wheel 84, which is arranged on the side of the main body 81 to facilitate the guidance and cooperation with the conveying part of the second conveying mechanism 70. With such a structural arrangement, it is convenient to clamp the silicon rod so that its position remains unchanged.

[0091] In this embodiment, the loading production line further includes a carrier 90, which is arranged on the first conveying mechanism 10. The carrier 90 includes a main body 91 and a partition 92. The main body 91 encloses a bearing space suitable for at least two silicon rods.

With such a structural arrangement, it is convenient to transport at least two silicon rods at the same time by the carrier 90, and the adjacent silicon rods are separated by the partition 92 to prevent the silicon rods from being damaged due to direct collision.

[0092] Specifically, the carrier 90 is compatible with silicon rods of various specifications such as 182 mm, 210 mm, and 230 mm.

The carrier guide wheel 93 is arranged on the side of the bottom plate 911 to facilitate the guiding cooperation with the conveying part of the first conveying mechanism 10.

[0094] Specifically, the bottom plate 911 , the first side plate 912 and the second side plate 913 are all made of ultra-high molecular weight polyethylene.

[0095] Specifically, there are at least two partitions 92, and at least two partitions 92 are arranged in the bearing space at intervals along the extension direction of the bearing space. Such a structural arrangement facilitates separation of adjacent silicon rods and prevents the silicon rods from being damaged due to direct collision.

[0096] Specifically, the partitions 92 are detachably arranged on the main body 91. With such a structural arrangement, the number of the partitions 92 can be adjusted according to the number of silicon rods.

[0097] Specifically, the partition plate 92 is movably arranged on the main body 91 along the extension direction of the bearing space. With such a structural arrangement, the position of the partition plate 92 can be adjusted according to the length of the silicon rod.
