Abstract
Description
Technical Field
[0001] This utility model relates to the field of new energy equipment manufacturing technology, and more specifically, to a battery cell flipping device. Background Technology
[0002] In production, there are sometimes requirements to flip the cut materials after cutting. For example, when cutting solar cells, it is usually necessary to flip the back side of the solar cell 180 degrees so that the front side is facing up, which is convenient for subsequent stacking and welding. Therefore, the solar cell flipping device plays a very important role in the solar cell processing system.
[0003] However, some existing cell flipping devices may cause the turntable to continue rotating after the cells have been flipped if the flipping sensor malfunctions. This can cause the cells on the support plate of the turntable to come into contact with the discharge track and continue rotating, which can easily lead to damage and fragmentation of the cells. Utility Model Content
[0004] The purpose of this invention is to provide a battery cell flipping device that can solve the problem of battery cell damage caused by sensor malfunction during the flipping process.
[0005] The embodiments of this utility model can be implemented as follows:
[0006] In a first aspect, this utility model provides a battery cell flipping device, comprising:
[0007] A turntable is equipped with a support component, which includes a tilting part. The tilting part includes a connecting shaft and a support plate connected together. The support plate is connected to the turntable through the connecting shaft, which is used to fix the support plate. The support plate has vacuum adsorption holes, which allow the support plate to adsorb material sheets. The turntable can drive the tilting part to rotate along a preset axis.
[0008] The support plate rotates relative to the turntable around the axis of the connecting shaft under the action of external force. After the external force disappears, the connecting shaft and the support plate are reset, and the axis of the connecting shaft is parallel to the surface of the support plate.
[0009] In an optional implementation, the connecting shaft is a torsion spring shaft with a preset torque.
[0010] In an optional embodiment, the turntable is provided with a plurality of support members arranged at intervals along the circumference of the turntable.
[0011] In an optional embodiment, there are two turntables, and the two turntables are arranged at an axial interval along the shaft. The support members on the two turntables are opposite to each other and are correspondingly arranged. The two turntables are divided into a first turntable and a second turntable. The support member on the first turntable is a first support member, and the support member on the second turntable is a second support member. Each first support member and the corresponding second support member are used to connect a material sheet.
[0012] Secondly, this utility model provides a battery cell flipping device according to claim 4, wherein a first turntable has a plurality of first support members arranged at intervals around its own circumference, and a second turntable has a plurality of second support members arranged at intervals around its own circumference, wherein the plurality of first support members on the first turntable and the plurality of second support members on the second turntable are arranged in a one-to-one correspondence.
[0013] In an optional embodiment, the support member further includes a locking part, which is arranged sequentially with the support plate in the first direction. The locking part is used to lock the support plate or to unlock it from the support plate. When the locking part is locked with the support plate and the support plate is subjected to a force in the second direction, the connecting plate is locked. When the locking part is unlocked from the support plate, the connecting plate can rotate around the axis of the connecting shaft in the first direction or the second direction under the action of an external force. The second direction is opposite to the first direction.
[0014] In an optional embodiment, the locking part is located on the side of the support plate away from the material sheet. The locking part includes a connecting part and a support pin. The connecting part is located on the turntable and has a through hole that is close to the preset axis relative to the support plate. The support pin is clearance-fitted with the through hole and can move relative to the through hole along its own axis to lock the support plate or release it from the support plate. The axis of the through hole is parallel to the axis of the connecting shaft, and the preset axis is perpendicular to the height direction.
[0015] In an optional embodiment, the turntable can rotate around a preset axis in a first direction. In the first direction, when the support plate rotates with the turntable around the preset axis in the first direction and when the support member rotates from the lowest point to the highest point, the support pin abuts against the side of the support plate away from the material. When the turntable rotates around the preset axis in the first direction and when the support member rotates from the highest point to the lowest point, the support pin disengages from the support plate, and the preset axis is perpendicular to the height direction.
[0016] In an optional embodiment, baffles are provided at both ends of the support pin along its own axial direction, and the baffles are used to abut against the end of the connecting part in the axial direction of the through hole.
[0017] In an optional embodiment, the cell flipping device further includes a rotating shaft, a turntable mounted on the rotating shaft, the axis of the rotating shaft being a preset axis, and the cell flipping device further includes a drive motor, the drive shaft of the drive motor being connected to the rotating shaft via a coupling.
[0018] This utility model provides a battery cell flipping device including a turntable with a support member mounted on it. The support member includes a flipping part, which includes a connecting shaft and a support plate connected to each other. The support plate is connected to the turntable via the connecting shaft, which is used to fix the support plate. The support plate has vacuum adsorption holes, through which it can adsorb battery cells. Under external force, the connecting shaft can drive the support plate to rotate along its own axis. After the external force disappears, the connecting shaft and the support plate return to their original positions. The axis of the connecting shaft is parallel to the surface of the support plate. The turntable can drive the flipping part to rotate along a preset axis. When the support plate contacts the battery cell on the discharge track and the turntable continues to rotate, the discharge track will exert a force on the support plate in the opposite direction to the rotation of the turntable. This will cause the support plate to rotate relative to the turntable around the axis of the connecting shaft, thereby reducing the pressure exerted by the support plate on the battery cell and solving the problem of battery cell damage caused by the failure of the flipping sensor.

[0030] It should be noted that the sheet material in this embodiment can be understood as a battery cell, in order to... Figure 1 For reference, the first direction is direction a.
[0031] Please refer to the patent drawings below for a detailed description of the specific structure of a battery cell flipping device 1 provided in this utility model embodiment and the corresponding technical effects it brings.
[0032] Please refer to Figures 1-3The present invention provides a battery cell flipping device 1, which includes a turntable and a support member 300 mounted on the turntable. The support member 300 includes a flipping part 310, which includes a connecting shaft 312 and a support plate 311 connected to each other. The support plate 311 is connected to the turntable through the connecting shaft 312. The connecting shaft 312 is used to fix the support plate 311. The support plate 311 has a vacuum adsorption hole, which can adsorb the material sheet 2. The connecting shaft 312 can drive the support plate 311 to rotate along its own axis under the action of external force. After the action of external force disappears, the connecting shaft 312 and the support plate 311 are reset. The axis of the connecting shaft 312 is parallel to the plate surface of the support plate 311. The turntable can drive the flipping part 310 to rotate along a preset axis.
[0033] In this embodiment, the axis of the connecting shaft 312 is perpendicular to the preset axis.
[0034] It should be noted that the connecting shaft 312 supports the plate 311 with a preset support force, which enables the plate 311 to adsorb the material piece 2 and make the material piece 2 rotate with the turntable, thereby realizing the flipping of the material piece 2. After the material piece 2 is flipped 180° under the drive of the support plate 311, the material piece 2 will enter the discharge track. At this time, the operator can break the vacuum of the support plate 311 that adsorbs the material piece 2 so that the material piece 2 falls onto the discharge track.
[0035] In some existing turntables, the support plate 311 is fixedly installed on the turntable and cannot rotate under the action of external force. Therefore, when the material piece 2 falls onto the discharge track and the flip sensor malfunctions, that is, when the material piece 2 moves onto the discharge track, the turntable cannot stop in time. As a result, the turntable continues to move, causing the support plate 311 to press on the material piece 2. Since the support plate 311 on some existing turntables is fixedly installed on the turntable, the support plate 311 is prone to crushing the material piece 2 during the continued rotation, causing damage to the material piece 2.
[0036] In this embodiment, since the support plate 311 is connected to the turntable via the connecting shaft 312, and the support plate 311 can rotate relative to the turntable around the axis of the connecting shaft 312 under the action of external force, that is, even if the sheet 2 falls from the support plate 311 onto the discharge track and the turntable continues to rotate, when the support plate 311 contacts the sheet 2 on the discharge track and the turntable continues to rotate, the discharge track will give the support plate 311 a force opposite to the direction of the turntable's rotation, which will cause the support plate 311 to rotate relative to the turntable around the axis of the connecting shaft 312, thereby reducing the pressing force of the support plate 311 on the sheet 2, so as to solve the problem of battery cell damage caused by the failure of the flip sensor.
[0037] In detail, in this embodiment, the connecting shaft 312 is a torsion spring shaft, which has a preset torque to enable the support plate 311 to support the sheet 2.
[0038] In this embodiment, a plurality of support members 300 are arranged at intervals along the circumference of the turntable. It can be understood that by setting up a plurality of support members 300, a plurality of material pieces 2 can be flipped during rotation, thereby improving the flipping efficiency of the material pieces 2.
[0039] Optionally, in this embodiment, there are two turntables, and the two turntables are arranged at intervals along the axial direction of the rotating shaft 400. The support members 300 on the two turntables are opposite to each other and are correspondingly arranged. The two turntables are a first turntable 100 and a second turntable 200. The support member 300 on the first turntable 100 is a first support member, and the support member 300 on the second turntable 200 is a second support member. Each first support member and the corresponding second support member are used to connect a material sheet 2.
[0040] Understandably, by setting up the first turntable 100 and the second turntable 200, the stability of the adsorption of the material piece 2 in the arrangement direction of the first turntable 100 and the second turntable 200 can be guaranteed when it is flipped, and the side tipping can be effectively avoided when flipping the material piece 2.
[0041] In detail, the first turntable 100 has multiple first support members arranged at intervals around its circumference, and the second turntable 200 has multiple second support members arranged at intervals around its circumference. The multiple first support members on the first turntable 100 and the multiple second support members on the second turntable 200 are set in a one-to-one correspondence.
[0042] It should be noted that the first support member on the first turntable 100 has the same structure as the second support member on the second turntable 200.
[0043] Optionally, the support member 300 further includes a locking part 320, which is arranged sequentially with the support plate 311 in the first direction. The locking part 320 is used to lock the support plate 311 or to unlock it from the support plate 311. When the locking part 320 is locked with the support plate 311 and when the support plate 311 is subjected to a force in the second direction, the connecting plate is locked. That is, at this time, the connecting part 321 cannot rotate relative to the turntable around the axis of the connecting shaft 312 in the second direction. When the locking part 320 contacts and locks with the support plate 311, the connecting plate can rotate around the axis of the connecting shaft 312 in the first or second direction under the action of external force. The first direction is opposite to the second direction.
[0044] Understandably, by setting the locking part 320, when the support plate 311 drives the material sheet 2 to flip and the vacuum is not broken to transport the material sheet 2 to the discharge track, the locking part 320 can lock the support plate 311 to ensure that the material sheet 2 is stably adsorbed on the support plate 311.
[0045] In detail, in this embodiment, the locking part 320 is disposed on the side of the support plate 311 away from the material sheet 2. That is, when the material sheet 2 is adsorbed onto the support plate 311, the locking part 320 is located on the side of the support plate 311 away from the material sheet 2. The locking part 320 includes a connecting part 321 and a support pin 322. The connecting part 321 is disposed on the turntable. The connecting part 321 has a through hole and is close to the preset axis relative to the support plate 311. The pin is clearance-fitted with the through hole and can move relative to the through hole along its own axis to lock the support plate 311 or release it from the support plate 311. The axis of the through hole is parallel to the axis of the connecting shaft 312.
[0046] In detail, the turntable can rotate around a preset axis in a first direction. In this first direction, and as the support plate 311 rotates along the preset axis in the first direction while the support member 300 rotates from its lowest point to its highest point, the support pin 322 abuts against the side of the support plate 311 away from the material sheet 2. This abuts against the side of the support plate 311 away from the side used to adsorb the material sheet 2, preventing the support plate 311 from rotating around the axis of the connecting shaft 312 under external force. During the rotation of the turntable around the preset axis in the first direction, and as the support member 300 rotates from its highest point to its lowest point, the support pin 322 disengages from the support plate 311, and the preset axis becomes perpendicular to the height direction.
[0047] As can be seen from the above, the support plate 311 of the multiple support members 300 arranged sequentially from the lowest point to the highest point along the first direction is abutted by the support pin 322. The support members 300 in this range are close to the feeding track, and the battery cells on the feeding track can be fed into the support members 300 so that they can be attracted by the first support member on the first turntable 100 and the corresponding second support member on the second turntable 200, and then rotated by the first turntable 100 and the second turntable 200 to be close to the discharge track.
[0048] Among them, the support pin 322 located at the highest point will move along the through hole under the action of gravity and eventually detach from the support plate 311.
[0049] In detail, in this embodiment, in order to prevent the support pin 322 from dislodging from the connecting part 321 when it moves through the hole relative to the connecting part 321, baffles 3221 are provided at both ends of the support pin 322 along its own axial direction. The baffles 3221 are used to abut against the end of the connecting part 321 in the direction of the through hole axis to prevent the support pin 322 from dislodging from the connecting part 321.
[0050] In this embodiment, the cell flipping device 1 further includes a rotating shaft 400, and a turntable is mounted on the rotating shaft 400. That is, in this embodiment, the first turntable 100 and the second turntable 200 are arranged at intervals along the axial direction of the rotating shaft 400. The axial direction of the rotating shaft 400 is a preset axial direction. The cell flipping device 1 also includes a drive motor 600. The drive shaft of the drive motor 600 is connected to the rotating shaft 400 through a coupling 500 to ensure the connection strength between the drive shaft of the drive motor 600 and the rotating shaft 400.
[0051] It should be noted that a vacuum tube is also provided in this embodiment, which is connected to the vacuum adsorption hole of the support plate 311 of the connector.
[0052] In summary, the battery cell flipping device 1 provided by this utility model embodiment includes a turntable, on which a support member 300 is installed. The support member 300 includes a flipping part 310, which includes a connecting shaft 312 and a support plate 311 connected together. The support plate 311 is connected to the turntable through the connecting shaft 312. The connecting shaft 312 is used to fix the support plate 311. The support plate 311 has a vacuum adsorption hole, through which the support plate 311 can adsorb the material sheet 2. Under the action of external force, the connecting shaft 312 can drive the support plate 311 to rotate along its own axis. After the action of external force disappears, the connecting shaft 312 and the support plate 311 are reset. The axis of the connecting shaft 312 is parallel to the plate surface of the support plate 311. The turntable can drive the flipping part 310 to rotate along a preset axis. After the support plate 311 contacts the material piece 2 on the discharge track and the turntable continues to rotate, the discharge track will give the support plate 311 a force opposite to the rotation direction of the turntable, which will cause the support plate 311 to rotate relative to the turntable around the axis of the connecting shaft 312, thereby reducing the pressing force of the support plate 311 on the material piece 2, so as to solve the problem of battery cell damage caused by the failure of the flip sensor.
[0053] 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.
