Description

Technical Field

[0001] This utility model relates to the field of battery processing, and in particular to a cell rounding detection and reversing device. Background Technology

[0002] For conventional button cell, cylindrical cell, and capacitor winding equipment on the market, the existing rotation methods are mostly cylinder clamping rotation or relying on cylinder clamping followed by motor-driven clamp rotation. Cylinder clamping rotation relies on the cylinder to clamp the cell from the material tray and then rotate it. The air source stability of the rotating cylinder is poor, resulting in poor synchronization. In the method of relying on cylinder clamping followed by motor-driven clamp rotation, the rotation speed of the cylinder is not as stable as that of the motor, and the efficiency is not as high as that of the motor. Moreover, the above clamping methods can also cause deformation of the battery and capacitor during the clamping process, or the clamping force is insufficient, causing the cell to fall off during rotation or the clamp to scratch the cell. Utility Model Content

[0003] To improve the stability of battery cell feeding, this utility model provides a cell roundness detection and commutation device.

[0004] This utility model provides a technical solution that adopts the following approach:

[0005] A cell roundness detection and commutation device, comprising:

[0006] A material handling assembly is used to pick up materials and move the battery cells onto a transfer assembly. The material handling assembly includes a drive component and a suction cup, which is used to pick up the battery cells from the material tray.

[0007] A transfer assembly is used to transfer battery cells from a pick-up assembly to a discharge assembly. The transfer assembly includes a first clamping member. When the transfer assembly transfers the battery cells, the pick-up assembly resets and picks up the cells again.

[0008] A feeding assembly is used to transfer battery cells to a processing device. The feeding assembly includes a second clamping member. When the feeding assembly feeds the battery cells, the picking assembly docks with the transfer assembly to pick them up.

[0009] The material handling assembly uses a drive unit and a suction cup to pick up the battery cell from the material tray and transfer it to the transfer assembly. Then, the drive unit moves the suction cup and the battery cell to the first clamping member. The suction cup brings the battery cell into the clamping center of the first clamping member. The first clamping member starts and clamps the battery cell. At this time, the suction cup leaks air and releases the battery cell. When the first clamping member can limit the displacement of the battery cell, the material handling assembly exits the first clamping member and resets to perform a second material handling.

[0010] After the first clamping component grips the battery cell, the transfer component and the unloading component move closer together, allowing the second clamping component to mate with the first clamping component and clamp the battery cell onto the second clamping component. Simultaneously, the first clamping component retracts to receive a battery cell retrieved by the picking component. At this point, the second clamping component immediately shifts and releases the battery cell after clamping. The picking component, transfer component, and unloading component relay the battery cell transfer, shortening the operation time required for sequential processing. Furthermore, the suction cup of the picking component protects the battery cell during movement, improving the stability of battery cell transfer and reducing breakage rate.

[0011] Preferably, the first clamping member includes four limiting rollers and a drive group. The length direction of the four limiting rollers is consistent. When the battery cell is clamped in the four limiting rollers, the four limiting rollers are evenly distributed around the circumference of the battery cell. The drive group drives the four limiting rollers to move closer to or away from the battery cell.

[0012] When the feeding assembly places the battery cell between its four limiting rollers, the drive unit drives the four limiting rollers to move toward each other, thereby clamping the battery cell. When it is necessary to transfer the battery cell to the second clamping member, the four limiting rollers can move away from each other.

[0013] The battery cell has tabs on both sides and four limiting rollers to securely restrain the battery cell. At the same time, the gaps between the limiting rollers can avoid the tabs, making the overall structure more reasonable.

[0014] The drive group can be configured as four cylinders or motors pointing to the same center, or as four horizontally driven motors or cylinders. Furthermore, the drive group can also be a device that drives the limiting rollers to move away from each other in multiple directions to avoid the material handling components.

[0015] Preferably, the second clamping member includes a pneumatic finger and a clamping cylinder, wherein the clamping cylinder drives the pneumatic finger to clamp.

[0016] The pneumatic fingers make the battery cells less likely to be damaged by being pinched or fall off the pneumatic fingers, and the pneumatic fingers are easy to adjust.

[0017] Preferably, the feeding assembly further includes a support frame and a rotary cylinder for driving the support frame to rotate. The rotary cylinder is also connected to a feeding cylinder and a discharging cylinder. The second clamping member is disposed on the support frame. The feeding cylinder drives the rotary cylinder to approach the first clamping member, and the discharging cylinder drives the rotary cylinder to approach the discharging point.

[0018] The rotary cylinder is activated, causing the second clamping member to rotate to a position directly opposite the first clamping member. Then, the feeding cylinder is activated, driving the pneumatic finger to approach the first clamping member for clamping. Alternatively, the first clamping member can be moved closer to the pneumatic finger, and then the clamping cylinder drives the pneumatic finger to clamp. Next, the feeding cylinder drives the rotary cylinder to retract, thus avoiding the first clamping member. Then, the rotary cylinder is activated, causing the pneumatic finger to rotate to a position directly opposite the discharge point. The discharge cylinder is then activated, driving the pneumatic finger to approach the discharge point. At this point, the clamping cylinder is activated, placing the battery cell at the discharge point, thus completing the transfer of the battery cell.

[0019] Preferably, the limiting roller is fitted with a bearing.

[0020] The bearings protect the battery cells, and their rotational arrangement relative to the limiting rollers converts the sliding friction between the battery cells and the limiting rollers into rolling friction, which helps reduce the wear on the battery cells when they are clamped on the limiting rollers.

[0021] Preferably, one of the limiting rollers has no sleeve bearing at its end, and the limiting roller is configured as a circular roller, which is connected to a rotating motor that drives the circular roller to rotate.

[0022] When the battery cell is held between the limiting rollers, the rounding roller rotates and works with other limiting rollers to round the battery cell. This helps improve the quality of the battery cell, reduces the occurrence of elliptical battery cells, and helps improve the yield rate.

[0023] Preferably, the bearing is detachably connected to the limiting roller.

[0024] The bearing can be detached from the end of the limiting roller, and a variety of bearing sizes can be selected to accommodate different sized battery cells.

[0025] Preferably, the transfer assembly includes an optical fiber sensor that emits detection light toward the clamping center of a plurality of limiting rollers, and the optical fiber sensor is used to detect the position of the tabs.

[0026] When the limiting roller clamps the battery cell, the battery cell rotates. When the fiber optic sensor detects the position of the tab and determines that the position of the tab can avoid the clamping body of the second clamping member, the battery cell stops rotating. This prevents the tab from being damaged when the battery cell is transferred between the first clamping member and the second clamping member, which helps to protect the battery cell tab.

[0027] Preferably, the fiber optic sensor is slidably disposed along the length direction of the limiting roller, and the transfer assembly is provided with an electric drive for driving the movement of the fiber optic sensor.

[0028] To adapt to different operating environments, the tabs on both sides of the battery cell can be positioned on the front, rear, or one in front of the other along the thickness direction of the cell. Therefore, by using an electric motor to drive the fiber optic sensor, various tab placement methods can be accommodated. In the frame of the device in this solution, a sliding hole is provided for inserting the sliding fiber optic sensor to improve its movement stability.

[0029] Preferably, the transfer assembly includes a laser ranging assembly that emits light toward the clamping center of the plurality of limiting rollers.

[0030] By combining the distance from the laser ranging component to the clamping center of the limiting roller and the distance from the peripheral wall of the battery cell detected by the laser ranging component, the diameter of the battery cell can be calculated, thereby detecting whether the diameter of the battery cell meets the standard.

[0031] In summary, this utility model has the following beneficial technical effects:

[0032] The material handling assembly uses a drive unit and a suction cup to pick up the battery cell from the material tray and transfer it to the transfer assembly. Then, the drive unit moves the suction cup and the battery cell to the first clamping member. The suction cup brings the battery cell into the clamping center of the first clamping member. The first clamping member starts and clamps the battery cell. At this time, the suction cup leaks air and releases the battery cell. When the first clamping member can limit the displacement of the battery cell, the material handling assembly exits the first clamping member and resets to perform a second material handling.

[0033] After the first clamping component grips the battery cell, the transfer component and the unloading component move closer together, allowing the second clamping component to mate with the first clamping component and clamp the battery cell onto the second clamping component. Simultaneously, the first clamping component retracts to receive a battery cell retrieved by the picking component. At this point, the second clamping component immediately shifts and releases the battery cell after clamping. The picking component, transfer component, and unloading component relay the battery cell transfer, shortening the operation time required for sequential processing. Furthermore, the suction cup of the picking component protects the battery cell during movement, improving the stability of battery cell transfer and reducing breakage rate.

[0036] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below.

[0037] This utility model discloses a cell rounding detection and commutation device.

[0038] Reference Figure 1 A cell rounding detection and commutation device, comprising:

[0039] The material handling assembly is used to pick up the material and move the battery cell 1 onto the transfer assembly. The material handling assembly includes a drive component and a suction cup, which is used to pick up the battery cell 1 from the material tray.

[0040] A transfer assembly is used to transfer the battery cell 1 from the pick-up assembly to the unloading assembly. The transfer assembly includes a first clamping member. When the transfer assembly transfers the battery cell 1, the pick-up assembly resets and picks up the battery cell again.

[0041] The feeding assembly is used to transfer the battery cell 1 to the processing device. The feeding assembly includes a second clamping member. When the feeding assembly feeds the battery cell 1, the picking assembly docks with the transfer assembly to pick up the battery cell 1.

[0042] In the attached diagram, the material handling assembly is not shown. The material handling assembly uses a drive unit and a suction cup to pick up the battery cell 1 from the material tray and transfer it to the transfer assembly. Then, the drive unit moves the suction cup and the battery cell 1 to the first clamping member. The suction cup brings the battery cell 1 into the clamping center of the first clamping member. The first clamping member is activated and clamps the battery cell 1. At this time, the suction cup leaks air and releases the battery cell 1. When the first clamping member can limit the displacement of the battery cell 1, the material handling assembly exits the first clamping member and resets to perform a second material handling.

[0043] After the first clamping component clamps the battery cell 1, the transfer component and the unloading component move closer together, causing the second clamping component to engage with the first clamping component and clamp the battery cell 1 onto the second clamping component. Simultaneously, the first clamping component retracts to receive the battery cell 1 from the second material handling component. At this point, the second clamping component immediately shifts and releases the battery cell 1 after clamping. The material handling component, transfer component, and unloading component relay the transfer of the battery cell 1, shortening the operation time required for sequential operation. Furthermore, the suction cup of the material handling component protects the battery cell 1 during movement, improving the stability of the battery cell 1 transfer and reducing the breakage rate.

[0044] Reference Figure 1 In this embodiment, the first clamping member includes four limiting rollers 2 and a drive group. The length direction of the four limiting rollers 2 is consistent. When the battery cell 1 is clamped in the four limiting rollers 2, the four limiting rollers 2 are evenly distributed around the battery cell 1. The drive group drives the four limiting rollers 2 to move closer to or away from the battery cell 1.

[0045] When the feeding assembly places the battery cell 1 between the four limiting rollers 2, the drive unit drives the four limiting rollers 2 to move toward each other, thereby clamping the battery cell 1. When it is necessary to transfer the battery cell 1 to the second clamping member, the four limiting rollers 2 can move away from each other.

[0046] Both sides of the battery cell 1 are provided with tabs 3. The four limiting rollers 2 can securely limit the battery cell 1. At the same time, the gap between the limiting rollers 2 can avoid the tabs 3, making the overall structure more reasonable.

[0047] The drive group can be configured as four cylinders or motors pointing to the same center, or as four horizontally driven motors or cylinders. Furthermore, the drive group can also be a device that drives the limiting rollers 2 to move away from each other in multiple directions to avoid the material handling components.

[0048] Reference Figure 1 In this embodiment, the second clamping member includes a pneumatic finger 4 and a clamping cylinder 5, and the clamping cylinder 5 drives the pneumatic finger 4 to clamp.

[0049] The pneumatic finger 4 makes the battery cell 1 less likely to be damaged by being pinched, and it is also less likely to fall off the pneumatic finger 4. In addition, the pneumatic finger 4 is easy to adjust.

[0050] Reference Figure 1 In this embodiment, the feeding assembly also includes a support frame and a rotating cylinder 7 for driving the support frame to rotate. The rotating cylinder 7 is also connected to a feeding cylinder and a feeding cylinder. The second clamping member is disposed on the support frame. The feeding cylinder drives the rotating cylinder 7 to approach the first clamping member, and the feeding cylinder drives the rotating cylinder 7 to approach the feeding point.

[0051] The rotary cylinder 7 is activated, causing the second clamping member to rotate to a position directly opposite the first clamping member. Then, the feeding cylinder is activated, driving the pneumatic finger 4 to approach the first clamping member for clamping. Alternatively, the first clamping member can move closer to the pneumatic finger 4. Then, the clamping cylinder 5 drives the pneumatic finger 4 to clamp. Next, the feeding cylinder drives the rotary cylinder 7 to retract, thus avoiding the first clamping member. Then, the rotary cylinder 7 is activated, causing the pneumatic finger 4 to rotate to a position directly opposite the discharge point. The discharge cylinder is then activated, driving the pneumatic finger 4 to approach the discharge point. At this point, the clamping cylinder 5 is activated, placing the battery cell 1 at the discharge point, thus completing the transfer of the battery cell 1.

[0052] Reference Figure 1 In this embodiment, the limiting roller 2 is fitted with a bearing 6.

[0053] The bearing 6 can protect the battery cell 1, and the bearing 6 is rotatably arranged relative to the limiting roller 2, which can convert the sliding friction between the battery cell 1 and the limiting roller 2 into rolling friction, which helps to reduce the wear of the battery cell 1 when it is clamped on the limiting roller 2.

[0054] Reference Figure 1 In this embodiment, the bearing 6 is detachably connected to the limiting roller 2.

[0055] The bearing 6 can be detached from the end of the limiting roller 2, and various sizes of bearing 6 can be selected to accommodate different sizes of battery cells 1.

[0056] Reference Figure 1 In this embodiment, one of the limiting rollers 2 has no sleeve bearing 6 at its end. The limiting roller 2 is set as a circular roller 9, which is connected to a rotating motor 10. The rotating motor drives the circular roller 9 to rotate.

[0057] When the battery cell 1 is clamped between the limiting rollers 2, the rounding roller 9 rotates and, together with the other limiting rollers 2, rounds the battery cell 1, which helps to improve the quality of the battery cell 1, reduces the occurrence of the battery cell 1 being elliptical, and helps to improve the yield.

[0058] Reference Figure 1 In this embodiment, the transfer assembly includes an optical fiber sensor 8, which emits detection light toward the clamping center of the plurality of limiting rollers 2. The optical fiber sensor 8 is used to detect the position of the tabs 3.

[0059] When the limiting roller 2 clamps the battery cell 1, the battery cell 1 rotates. When the fiber optic sensor 8 detects the position of the tab 3 and determines that the position of the tab 3 can avoid the clamping body of the second clamping member, the battery cell 1 stops rotating. This prevents the tab 3 from being damaged when the battery cell 1 is transferred between the first clamping member and the second clamping member, which helps to protect the tab 3 of the battery cell 1.

[0060] Reference Figure 1 In this embodiment, the fiber optic sensor 8 is slidably disposed along the length direction of the limiting roller 2, and the transfer assembly is provided with an electric drive for driving the fiber optic sensor 8 to move.

[0061] To adapt to different operating environments, the tabs 3 on both sides of the battery cell 1 can be positioned on the front or rear side, or one in front of the other on both sides of the battery cell 1 along its thickness. Therefore, by using an electric motor to drive the fiber optic sensor 8 to slide, various tab 3 positioning methods can be accommodated. In the frame of the device in this solution, a sliding hole is provided for inserting the sliding fiber optic sensor 8 to improve the movement stability of the fiber optic sensor 8.

[0062] Reference Figure 1 In this embodiment, the transfer component includes a laser ranging component, which emits light toward the clamping center of the plurality of limiting rollers 2.

[0063] By combining the distance from the laser ranging component to the clamping center of the limiting roller 2 and the distance from the peripheral wall of the battery cell 1 detected by the laser ranging component, the diameter of the battery cell 1 can be calculated, thereby detecting whether the diameter of the battery cell 1 meets the standard.

[0064] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
