Description

Technical Field

[0001] This utility model relates to the field of solar cell production equipment technology, and more specifically, to a flipping device for reducing camera misjudgment and a solar cell production equipment. Background Technology

[0002] In the production of solar cells, cell fragments may be generated at multiple stages. If these fragments are not cleaned up in time, they will greatly affect the cleanliness of the manufacturing environment. For example, they can affect automatic detection devices for film color and appearance, causing them to misjudge the presence of fragments. Specifically, when cell fragments are present on the red background plate of the automatic detection device, the device may misjudge the cells, resulting in a large number of normal cells being mistakenly identified as defective and rejected. In this case, manual inspection is required, meaning that on-site workers need to enter the main unit to remove the fragments from the background plate.

[0003] Although there are technologies that provide tilted slides to allow debris to slide off and collect the debris, these tilted slides are difficult to clean up completely and are not suitable for scenarios that require the use of colored (e.g., red) backgrounds to inspect battery cells. Utility Model Content

The flipping device that reduces camera misjudgment can be used in battery cell production equipment. It can reliably pour out the fragments on the background plate, which greatly reduces the problem of misjudgment of battery cells by the detection device (e.g., camera). This is beneficial to improving the output and production efficiency of battery cells, and reduces the probability of manual entry into the main machine to clean the fragments, thus reducing the probability of dirt caused by human intervention.

The ends of the first side plate away from the base plate, the second side plate away from the base plate, the third side plate away from the base plate, and the fourth side plate away from the base plate together form a drop opening. The first side plate has an insertion opening.

[0017] In an optional implementation, the flipping device for reducing camera misjudgment also includes a collection box located below the flipping frame for collecting debris that falls from the background plate placed in the receiving slot.

[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] This embodiment provides a solar cell production equipment, which includes a solar cell conveying device and a testing device; the solar cell conveying device is used to convey solar cells, and the testing device is used to detect whether the solar cells conveyed on the solar cell conveying device are qualified solar cells.

[0035] Alternatively, the cell conveying device may refer to a conveyor belt assembly, the working principle and structure of which are similar to related technologies and will not be described in detail here.

[0036] Optionally, the inspection device may refer to a PECVD camera, which can be used in conjunction with a colored (e.g., red) background to inspect the film color and appearance of the solar cells transported by the solar cell transport device. The structure and working principle of the inspection device are similar to related technologies and will not be described in detail here.

[0037] To prevent fragments from falling onto the background panel used with the testing device and causing qualified (normal) solar cells to be mistakenly identified as unqualified, please refer to... Figure 1 The battery cell production equipment in this embodiment also includes a flipping device 010 to reduce camera misjudgment. The flipping device includes a flipping frame 100 and a driving mechanism 200. The flipping frame 100 is provided with a receiving groove 110, an insertion port 111, and a drop port 112. The insertion port 111 and the drop port 112 are both connected to the receiving groove 110. The orientation of the insertion port 111 and the orientation of the drop port 112 are distributed at an angle. The insertion port 111 is used to pick up and put the background plate into the receiving groove 110, and the drop port 112 is used to let the fallen battery cell fragments fall into the receiving groove 110. The driving mechanism 200 is connected to the flipping frame 100 for driving the flipping frame 100 to rotate so as to pour out the fragments on the background plate placed in the receiving groove 110.

[0038] The flipping device can empty the fragments from the background plate, greatly reducing the problem of misjudging the battery cells by the detection device (e.g., camera). This helps to improve the output and production efficiency of the battery cells, and reduces the probability of manual entry into the main unit to clean the fragments, thus reducing the probability of dirt caused by human intervention. Moreover, after the fragments are emptied from the receiving slot 110 of the flipping frame 100, the flipping frame 100 can be reset under the drive of the drive mechanism 200, so that the background plate in the receiving slot 110 can continue to be used in conjunction with the detection device to detect whether the battery cells are qualified.

[0039] It should be noted that the drop opening 112 is configured to face upwards to ensure that fragments falling from the battery cells reliably fall from the drop opening 112 into the receiving slot 110.

[0040] Optionally, the angle between the orientation of the drop-out 112 and the orientation of the insertion port 111 is 90°; of course, in other embodiments, the angle between the orientation of the drop-out 112 and the orientation of the insertion port 111 is 88°, 93°, etc., which are not specifically limited here.

[0041] Optionally, the flip frame 100 is positioned below the cell conveying device so that the cells conveyed by the cell conveying device can pass over the flip frame 100. The detection device is positioned above the cell conveying device and distributed opposite to the flip frame 100. In this way, when the cells conveyed by the cell conveying device move between the detection device and the flip frame 100, the detection device and the background plate inside the flip frame 100 can be used to reliably detect whether the cells are qualified and ensure that the fragments falling from the cells can reliably enter the receiving groove 110 of the flip frame 100.

[0042] Alternatively, please refer to Figure 1 The flipping device 010, which reduces camera misjudgment, includes a track 300 and a drive mechanism 200 including a motor 210. The motor 210 is configured to slide relative to the track 300 for easy mounting and dismounting. The motor 210 is also connected to the flipping frame 100 for driving the frame to rotate, thereby emptying the fragments from the background board placed in the receiving slot 110. Configuring the motor 210 to slide relative to the track 300 ensures the ease of assembly of the drive mechanism 200; driving the flipping frame 100 to rotate using the motor 210 ensures the reliability of emptying the fragments from the background board placed in the receiving slot 110.

[0043] Furthermore, the drive mechanism 200 also includes a drive shaft 220 and a first slider 230. The flip frame 100 is driven by the output shaft of the motor 210 via the drive shaft 220, and the drive shaft 220 is rotatably inserted into the first slider 230. That is, one end of the drive shaft 220 is driven by the output shaft of the motor 210, and after the drive shaft 220 passes through the first slider 230, its other end is fixedly connected to the flip frame 100. The first slider 230 is slidably connected to the track 300. The arrangement of the first slider 230 and the drive shaft 220 ensures the ease of operation of rotatably mounting the motor 210 onto the track 300, while also ensuring that the motor 210 reliably drives the flip frame 100 to rotate via the drive shaft 220.

[0044] Furthermore, the drive mechanism 200 also includes a support shaft 240 and a second slider 250. The flipping frame 100 has a first side and a second side distributed opposite to each other. The drive shaft 220 is connected to the first side, and the second side is connected to the support shaft 240. The drive shaft 220 and the support shaft 240 are coaxially distributed. The support shaft 240 is rotatably inserted into the second slider 250, and the second slider 250 is slidably connected to the track 300. The arrangement of the second slider 250 and the support shaft 240 ensures the reliability and stability of the flipping frame 100 rotating under the drive of the motor 210.

[0045] The first slider 230 and the second slider 250 have similar structures. Here, we will only use the first slider 230 and its assembly structure with the track 300 as an example for explanation; please refer to... Figure 1 , Figure 2 and Figure 3 The track 300 includes a track body 310 and a first limiting rib 320. The track body 310 is provided with a groove 311, and the first limiting rib 320 is connected to the track body 310. The first slider 230 includes a slider body 231 and a second limiting rib 232 connected to the slider body 231. Parts of the slider body 231 and the second limiting rib 232 can both move along a first direction ( Figure 1 The slider body 231 (in the direction of arrow ab) can be slidably inserted into the groove 311, and the first limiting rib 320 can abut against the second limiting rib 232 to prevent the slider body 231 from moving along the second direction ( Figure 1 The slider 230 disengages from the slide groove 311 in the direction of the central (cd) arrow, wherein the first direction and the second direction are distributed at an angle. This arrangement ensures both the ease of assembly of the first slider 230 onto the track 300 and the stability of the first slider 230 in the second direction after it is assembled onto the track 300.

[0046] Furthermore, the slide 311 has a first groove 312 and a second groove 313. The first groove 312 is located at the end of the slide 311 in the length direction, and the second groove 313 is located at the end of the slide 311 in the depth direction. The first limiting rib 320 is located at the second groove 313, and the slider body 231 and the second limiting rib 232 can be loaded and unloaded from the first groove 312 into the slide 311.

[0047] The connection between the first limiting rib 320 and the track body 310 includes, but is not limited to, integral molding and welding; the connection between the second limiting rib 232 and the slider body 231 includes, but is not limited to, integral molding and welding.

[0048] In this embodiment, the first direction is the length extension direction of the slide groove 311, and the angle between the first direction and the second direction is 90°. Of course, in other embodiments, the angle between the first direction and the second direction can also be 88°, 92°, etc., and is not specifically limited here.

[0049] Optionally, the insertion port 111 is oriented towards the motor 210. Of course, in other embodiments, the insertion port 111 may also be oriented away from the track 300 or away from the motor 210, which is not specifically limited here.

[0050] It should be noted that a drive mechanism 200 can be installed on the track 300, and a flip frame 100 is set for each drive mechanism 200; of course, drive mechanisms 200 can be installed on both sides of the track 300, that is, two drive mechanisms 200 can also be installed on the track 300, and the two drive mechanisms 200 are respectively connected to a flip frame 100.

[0051] Optionally, the drive mechanism 200 also includes a coupling (not shown in the figure), and the motor 210 is connected to the flipping frame 100 through the coupling; specifically, the motor 210 is connected to the drive shaft 220 through the coupling, and the drive shaft 220 is used to achieve the transmission connection with the flipping frame 100.

[0052] Alternatively, please refer to Figure 4 The flip frame 100 includes a base plate 101 and a first side plate 102, a second side plate 103, a third side plate 104 and a fourth side plate 105 connected to the base plate 101. The first side plate 102, the second side plate 103, the third side plate 104 and the fourth side plate 105 are connected end to end at an angle. The first side plate 102, the second side plate 103, the third side plate 104 and the fourth side plate 105 together form a receiving groove 110. The end of the first side plate 102 away from the base plate 101, the end of the second side plate 103 away from the base plate 101, the end of the third side plate 104 away from the base plate 101 and the end of the fourth side plate 105 away from the base plate 101 together form a drop opening 112. The first side plate 102 has an insertion opening 111.

[0053] Of course, in other embodiments, the insertion port 111 may also be provided with a second side plate 103 or a third side plate 104, which is not specifically limited here.

[0054] Furthermore, the drive shaft 220 and the support shaft 240 are respectively connected to the first side plate 102 and the third side plate 104, and the connection methods include but are not limited to welding, bonding, and threaded connection.

[0055] The included angles of the first side plate 102 and the second side plate 103, the included angles of the second side plate 103 and the third side plate 104, the included angles of the third side plate 104 and the fourth side plate 105, and the included angles of the fourth side plate 105 and the first side plate 102 are including but not limited to 90°, 89°, 91°, etc.

[0056] Optionally, the flip frame 100 also includes a flange 106. The ends of the first side plate 102 away from the bottom plate 101, the second side plate 103 away from the bottom plate 101, the third side plate 104 away from the bottom plate 101, and the fourth side plate 105 away from the bottom plate 101 are all connected to the flange 106. The flange 106 is used to prevent the background plate from falling out of the receiving groove 110 from the drop hole 112. That is, when the drive mechanism 200 drives the flip frame 100 to flip so that the drop hole 112 faces down, the flange 106 can abut against the background plate to prevent the background plate from falling out of the receiving groove 110 from the drop hole 112.

[0057] Of course, in other embodiments, the flip frame 100 may not include the flange 106, and the background plate may be fixed in the receiving groove 110 by means of adhesive or other methods.

[0058] Optionally, the flipping device 010, which reduces camera misjudgment, also includes a collection box 400, which is located below the flipping frame 100 and is used to collect debris that falls from the background plate placed in the receiving slot 110. Using the collection box 400 to collect debris improves the cleanliness of the battery cell production process.

[0059] In this embodiment, the battery cell production equipment transports battery cells by a battery cell conveying device during battery cell production. When a battery cell passes through the flipping frame 100, any fragments falling from the battery cell can enter the receiving groove 110 of the flipping frame 100. When no battery cell passes through the flipping frame 100, the flipping frame 100 is driven to rotate by the motor 210 so that the drop outlet 112 faces downward, allowing the fragments placed on the background plate in the receiving groove 110 to be poured out.

[0060] It should be noted that the time for the battery cell conveying device to convey the battery cells through the flipping frame 100 is usually fixed. Therefore, the motor 210 can be configured to drive the flipping frame 100 to rotate at a fixed time period to dump out the fragments. The fixed time mentioned above can refer to a fixed moment or a fixed time interval.

[0061] In summary, the flipping device 010 of this utility model for reducing camera misjudgment can be used in battery cell production equipment. It can reliably pour out the fragments on the background plate, greatly reducing the problem of misjudgment of battery cells by the detection device (e.g., camera), which is conducive to improving the output and production efficiency of battery cells, and reducing the probability of manual entry into the main unit to clean the fragments, thus reducing the probability of dirt caused by human intervention.

[0062] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
