Description

Technical Field

[0001] This utility model relates to the field of battery cell texturing technology, specifically to a flipping mechanism and a battery cell texturing device having the same. Background Technology

[0002] Before applying a UV coating to the surface of the battery cell, its six sides need to be roughened using a laser. Currently, this is typically done by a conveyor line that moves the battery cell sequentially through the working areas of various laser generators. To ensure stable movement of the battery cell on the conveyor line, a fixture is installed to clamp the cell along the conveying direction. Therefore, only the vertically upward side and the two sides perpendicular to the conveying direction are exposed. After the preceding laser generator roughens these three sides, a flipping mechanism is needed to flip the battery cell, exposing the other three sides.

[0003] The existing flipping mechanism requires first rotating the battery cell 180° around the conveying direction as the axis, and then rotating the battery cell 90° in the horizontal plane to expose the other three sides of the battery cell. Although this can also achieve the flipping of the battery cell, the operation is cumbersome and requires moving the battery cell twice, resulting in low production efficiency. Utility Model Content

[0040] The technical solution provided by this utility model has the following advantages:

[0041] 1. This utility model provides a flipping mechanism, which includes a flipping drive and a clamping member.

[0042] This structure requires only one mechanism to rotate the gripper 90° in the horizontal plane and flip it over simultaneously with a single action. This exposes the other three sides of the battery cell, improving the flipping efficiency.

[0043] 2. This utility model provides a battery cell texturing device, which includes a conveying mechanism, two sets of texturing processors, and a flipping mechanism. The conveying mechanism is used to convey battery cells in a first direction.

The flipping mechanism is disposed between the first and second conveying sections. The flipping mechanism is used to flip the battery cells on the first conveying section and place them on the second conveying section, so that the battery cells switch from the first state to the second state.

[0044] This structure utilizes a first positioning component to match the front and rear surface texturing processors, and a second positioning component to match the upper surface texturing processor. After the battery cell is transported to the texturing station via a conveyor line, the positioning component clamps and fixes the battery cell, calibrates its position, and prevents the battery cell from shaking during texturing, which would affect the texturing effect.

[0064] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0065] Example 1

[0066] This embodiment provides a flipping mechanism 1, such as... Figures 1 to 2 As shown, it includes a flipping drive 11, a clamping member 12, a rotating plate 13, and a fixing plate 14.

[0067] like Figure 1 As shown, the flipping drive 11 is a rotary motor. In this embodiment, the flipping drive 11 is placed vertically, and its rotation axis at the drive end is in the horizontal direction. The rotating plate 13 is installed at the drive end of the flipping drive 11, and the rotating plate 13 is perpendicular to the rotation axis of the drive end of the flipping drive 11. The fixing plate 14 and the rotating plate 13 are an integrated structure. The fixing plate 14 is fixed to the side of the rotating plate 13, and the included angle between the rotating plate 13 and the fixing plate 14 is greater than 90°. The clamping member 12 is installed on the fixing plate 13. The angle between the rotating plate 13 and the fixing plate needs to ensure that the rotation axis of the drive end of the flipping drive 11 intersects the clamping direction of the clamping member 12. The preset axis is the rotation axis of the drive end of the flipping drive 11.

[0068] The clamping component 12 includes a drive cylinder 122 and a gripper 121. The drive cylinder 122 is a double-headed cylinder and is fixed on the fixing plate 14. There are two grippers 121, which are symmetrically arranged on the two drive ends of the drive cylinder 122. The extension lines of the axis of symmetry of the two grippers 121 are perpendicular to the fixing plate 14.

[0069] like Figure 3 As shown, when it is necessary to change the state of cell 2, for example, from Figure 3 The front, vertically placed orientation is changed to the back, horizontally placed orientation.

[0070] Two grippers 121 are used to hold the battery cell 2. A drive cylinder 122 drives the two grippers 121 to move away from each other until the distance between them is greater than the length of the battery cell 2, forming a clamping space. The two grippers 121 are then moved to the sides of the battery cell 2 until it is within the clamping space. The drive cylinder 122 then drives the two grippers 121 to come closer together and fit against the sides of the grippers 121 to hold the battery cell 2 in its upright position. The flipping drive 11 is activated, rotating 180 degrees counterclockwise or clockwise, flipping the battery cell 2 to its reverse, horizontal position. The drive cylinder 122 then drives the two grippers 121 to move away from each other again, releasing the flipped battery cell 2. The integrated rotating plate 13 and fixed plate 14 drive the gripper 12 to flip, requiring only one mechanism to perform a single action to rotate the grippers 121 90° horizontally while simultaneously flipping the battery cell 2. This changes the position of cell 2, exposing the other three sides and improving the flipping efficiency.

[0071] In this embodiment, preferably, after the two grippers 121 clamp the battery cell 2, the rotation axis of the drive end of the flipping drive 11 passes through the center of the battery cell 2. This ensures that along... Figure 3The clamping direction of the clamping member 12 on the front flipping mechanism 1 is such that the axis of symmetry of the battery cell 2 in the first direction before flipping coincides with the axis of symmetry in the first direction after flipping, which facilitates subsequent processing.

[0072] Example 2

[0073] This embodiment provides a cell texturing device, such as... Figures 3 to 8 As shown, the cell texturing device includes a conveying mechanism 3, two sets of texturing processors, and the flipping mechanism 1 in Embodiment 1. As... Figure 4 and Figure 8 As shown, direction A is the conveying direction, which is the first direction.

[0074] like Figure 3 and Figure 4 As shown, the conveying mechanism 3 is used to convey the battery cell 2 in a first direction. The conveying mechanism 3 includes a first conveying section 31 and a second conveying section 32 arranged sequentially along the first direction. The battery cell 2 on the first conveying section 31 is in a first state of facing vertically, that is, when on the first conveying section 31, the extension line of the long side of the battery cell 2 extends in the first direction. The battery cell 2 on the second conveying section 32 is in a second state of facing horizontally, that is, when on the second conveying section 32, the extension line of the wide side of the battery cell 2 extends in the first direction.

[0075] like Figure 4 and Figure 5 As shown, two sets of texturing processors are respectively located on the sides of the first conveying section 31 and the second conveying section 32. Specifically, taking the set of texturing processors located in the first conveying section 31 as an example, its specific structure is explained. The structure and installation position of the set of texturing processors in the second conveying section 32 are the same as those of the corresponding texturing processors in the first conveying section 31. Figure 5 As shown, the texturing processor includes a front surface texturing processor 41, a rear surface texturing processor 42, and an upper surface texturing processor 43. The front surface texturing processor 41 is installed in front of the first conveying section 31, with its output end facing the first conveying section 31 and at the same level as the front surface of the battery cell 2. The rear surface texturing processor 42 is installed behind the first conveying section 31, with its output end facing the first conveying section 31 and at the same level as the rear surface of the battery cell 2. The fixed end of the upper surface texturing processor 43 is installed behind the first processing section, and its output end is located above the end of the first output section, directly facing the upper surface of the battery cell 2 on the first conveying section 31.

[0076] like Figure 4As shown, the flipping mechanism 1 is disposed between the first conveying section 31 and the second conveying section 32. The flipping mechanism 1 is used to switch the battery cell 2 in the first state on the first conveying section 31 to the battery cell 2 in the second state. In this embodiment, as... Figure 3 As shown, the flipping mechanism 1 also includes a base 15, a sliding module 16, and a lifting module 18. The base 15 is installed on the ground between the first output section and the second output section, located on one side. The sliding module 16 is installed on the base 15, and a first bracket 17 is installed on the sliding end of the sliding module 16. The lifting module 18 is fixed to the side of the first bracket 17 near the conveying mechanism 3, and the lifting end of the lifting module 18 is located near the conveying mechanism 3. A second bracket 19 is installed on the lifting end, and two flipping mechanisms 1 are spaced apart along the first direction on the side of the second bracket 19 near the conveying mechanism 3. Specifically, the flipping drive component 11 of the flipping mechanism 1 is fixed to the second bracket 19, and the flipping drive component 11 is inclined, that is, the extension direction of the rotation axis of the flipping drive component 11 intersects the first direction, with an intersection angle preferably of 45 degrees. The sliding module 16 can drive the lifting module 18 and the flipping mechanism 1 to reciprocate along the first direction via the first bracket 17. The lifting module 18 can drive the flipping mechanism 1 to vertically lift up and down via the second bracket 19. Preferably, the second bracket 19 is provided with two flipping drive members spaced apart along the first direction, which can respectively drive a pair of grippers 121 to work. Figure 3 The two flipping drive units in the diagram drive different cells 2 to different positions only for ease of understanding. In actual operation, the two flipping drive units can work synchronously.

[0077] In this embodiment, as Figure 5As shown, the conveying mechanism 3 includes a driving component 33, a conveying component 34, and limiting components 5. The driving component 33 consists of a horizontally placed motor and a conveying roller, and the conveying component 34 is a conveyor belt fitted onto the conveying roller. A plurality of limiting components 5 are spaced apart along a first direction on the outer surface of the conveying component 34. Specifically, the limiting components 5 include a first stop 51, a second stop 52, a first pad 53, and a second pad 54. The first stop 51, the first pad 53, the second pad 54, and the second stop 52 are sequentially arranged on the conveying component 34 along the first direction. The thickness of the first pad 53 is less than the thickness of the second pad 54, so that the bearing surface on the upper side of the first pad 53 is lower than the bearing surface on the upper side of the second pad 54. The distance between the first stop 51 and the second pad 54 is equal to the width of the battery cell 2, allowing the battery cell 2 to be secured above the first pad 53 between the first stop 51 and the second pad 54. The bearing surface of the first pad 53 alone supports the battery cell 2 in the second position. The first stop 51 and the second pad 54 are attached to the two longer side end faces of the battery cell 2. The distance between the opposing walls of the first stop 51 and the second stop 52 is equal to the length of the battery cell 2. The battery cell 2 in the first position is placed between the first stop 51 and the second stop 52. The thickness of the second pad 54 is the same as the thickness of the base plate of the first stop 51 and the second stop 52. The first stop 51, the second stop 52 and the second pad 54 together support the battery cell 2 in the first position. The first stop 51 and the second stop 52 are attached to the two narrower side end faces of the battery cell 2.

[0078] Specifically, in this embodiment, such as Figure 8 As shown, the first stop 51 and the second stop 52 are L-shaped blocks arranged opposite each other. A clearance opening is provided below the two grippers 121 to allow passage between the first stop 51 and the second stop 52. The diameter of the clearance opening is larger than the width of the first stop 51 and the second stop 52 themselves. When the grippers 121 hold the battery cell in its first state, the clearance opening faces the first stop 51 and the second stop 52, and the battery cell is held by the stop plates on both sides of the clearance opening. At this time, the first stop 51 and the second stop 52 are located within the clearance opening.

[0079] In this embodiment, as Figure 5 As shown, the cell texturing device also includes a positioning mechanism 6, which is provided on both the first conveying section 31 and the second conveying section 32. Specifically, the positioning mechanism 6 includes a first positioning component 61 and a second positioning component 64.

[0080] like Figure 6As shown, the first positioning component 61 is configured to correspond to the front surface texturing processor 41 and the rear surface texturing processor 42. The first positioning component 61 includes a first positioning support frame 62, a main positioning unit 67, and a first auxiliary positioning unit 63. The first positioning support frame 62 can be fixed to the ground or the conveying mechanism 3, maintaining its position. The first positioning support frame 62 has a gantry-like structure, allowing the rear surface texturing processor 42 to pass through the first positioning support frame 62 and contact the rear surface of the battery cell 2. The main positioning unit 67 in the first positioning component 61 is vertically positioned on one side of the conveyor 34. The main positioning unit 67 is installed on the side of the first positioning support frame 62 near the battery cell 2. The main positioning unit 67 includes a positioning drive component 671, a sliding component 672, and a leveling component 673. The positioning drive component 671 can be a bidirectional cylinder. The movement direction of one drive end of the positioning drive component 671 is the same as the first direction, and the movement direction of the other drive end is opposite to the first direction. Two sliding components 672 are provided, and the upper ends of the two sliding components 672 are respectively fixed to the two drive ends of the positioning drive component 671. The two sliding components 672 are symmetrically arranged. The leveling component 673 is a combination of a V-shaped swing arm and a leveling wheel. The middle part of the V-shaped swing arm is rotatably mounted on the first positioning support frame 62. The upper end of the V-shaped swing arm is hinged to the output end of the positioning drive component 671, and the lower end of the V-shaped swing arm is equipped with a leveling wheel. Two leveling components 673 are also provided, and the two leveling components 673 are respectively fixed to the lower ends of the two sliding components 672 near the conveying mechanism 3. One of the sliding components 672 has a first guide surface 674 inclined towards the regularizing component 673 on the side away from the regularizing component 673. The first auxiliary positioning unit 63 includes a first clamping block 631, a first connecting rod 632, a first return spring 633, and a first guide wheel 634. The first clamping block 631 is vertically mounted on the first positioning support frame 62. The first clamping block 631 is connected to the lower end of the first connecting rod 632. The upper end of the first connecting rod 632 is rotatably connected to a first guide wheel 634, which is adapted to rest on the first guide surface 674. The lower end of the first return spring 633 is fixed to the first clamping block 631, and the upper end of the first return spring 633 is fixed to the positioning protrusion of the first positioning support frame 62.

[0081] like Figure 7As shown, the second positioning component 64 is positioned corresponding to the upper surface texturing processor 43. The second positioning component 64 includes a second positioning support frame 65, a main positioning unit 67, and a second auxiliary positioning unit 66. Two second positioning support frames 65 are provided, each fixed to one side of the conveyor 34. Two main positioning units 67 are provided, positioned opposite each other and fixed to the two side second positioning support frames 65. The main positioning units 67 in the second positioning component 64 are horizontally placed. The structure of the main positioning units 67 in the second positioning component 64 is the same as that in the first positioning component 61, with improvements made only to ensure clamping stability and adaptability dimensions; further details are omitted here.

[0082] like Figure 7 As shown, in the second positioning assembly 64, any sliding member 672 of the two main positioning units 67 has a second guide surface 675 inclined towards the regularizing member 673 on the side away from the regularizing member 673. Two second auxiliary positioning units 66 are also provided, corresponding to the two main positioning units 67 respectively. Taking one as an example, its specific structure is described as follows: the second auxiliary positioning unit 66 includes a second clamping block 661, a second connecting rod 662, a second return spring 663, and a second guide wheel 664. The first clamping block 631 is mounted on the second positioning support frame 65. The second clamping block 661 is connected to the end of the second connecting rod 662 near the battery cell 2. The end of the first connecting rod 632 away from the battery cell 2 is rotatably connected to a second guide wheel 664, which is adapted to rest on the second guide surface 675. The end of the second return spring 663 near the battery cell 2 is fixed to the second clamping block 661, and the side of the second return spring 663 away from the battery cell 2 is fixed to the second positioning support frame 65.

[0083] Taking a battery cell 2 as an example, the working principle of the battery cell texturing device is explained. When the battery cell 2 needs to be texturized, firstly, the upstream feeding structure places the battery cell 2 on the positioning mechanism 6 on the first conveying section 31. At this time, the battery cell 2 is in the first vertical position, placed on the upper surface of the first stop 51, the second stop 52, and the second pad 54. The first stop 51 and the second stop 52 are close to the side of the battery cell 2. Then, it will first reach the working area between the front surface texturing processor 41 and the rear surface texturing processor 42, where the first positioning component 61 is also located. Figure 6As shown, when the battery cell 2 is about to reach below the first positioning assembly 61, the positioning drive 671 in the first positioning assembly 61 is driven. The positioning drive 671 drives the sliding members 672 on both sides to move towards each other. Under the principle of leverage, the right-side alignment member 673 rotates counterclockwise, and the left-side alignment member 673 rotates clockwise, until the height of the alignment wheel in the alignment member 673 is higher than the upper surface of the battery cell 2. At this time, the first guide wheel 634 moves along the first guide surface 674, thereby driving the entire first auxiliary positioning unit 63 to move upward, squeezing the first return spring 633. When the battery cell 2 reaches the middle of the two alignment members 673, the conveyor 34 stops. The positioning drive 671 in the first positioning assembly 61 restarts, driving the two sliding members 672 to move away from each other. Under the principle of leverage, the right-side alignment member 673 rotates clockwise, and the left-side alignment member 673 rotates counterclockwise, until the two alignment members 673 respectively adhere to the two smaller side surfaces of the battery cell 2 that intersect with the axis of the first direction, thereby restricting the movement of the battery cell 2 in the first direction. At the same time, as the two sliding members 672 move away from each other, the first guide wheel 634 moves diagonally downward on the first guide surface 674, and the first return spring 633 resets, using its elastic force to drive the entire first auxiliary positioning unit 63 downward until the first pressing block 631 presses against the upper surface of the battery cell 2, pressing the entire battery cell 2 onto the first conveying section 31.

[0084] After the above steps, the battery cell 2 is fixed between the first stop 51 and the second stop 52, leaving only the front and rear sides of the battery cell 2, formed by the long side and the height, exposed. The front and rear surfaces of the battery cell 2 are then cleaned by the front surface roughening processor 41 and the rear surface roughening processor 42, respectively. After cleaning, the positioning drive 671 in the first positioning assembly 61 is driven. The positioning drive 671 drives the two sliding parts 672 to move closer to each other. Under the principle of leverage, the right-side leveling part 673 rotates counterclockwise, and the left-side leveling part 673 rotates clockwise. The leveling part 673 moves away from the surface of the battery cell 2 until the height of the leveling wheel in the leveling part 673 is higher than the upper surface of the battery cell 2. At the same time, the first guide wheel 634 moves along the first guide surface 674, thereby driving the entire first auxiliary positioning unit upwards, away from the upper surface of the battery cell 2. Restarting the drive unit 33 causes the conveyor 34 to continue moving, transporting the battery cell 2 along the first direction. When it is about to reach the position of the second positioning component 64, the positioning drive unit 671 in the second positioning component 64 is activated. The positioning drive unit 671 causes the sliding parts 672 on both sides to move in a direction closer to each other. Figure 7From a top-down perspective, in the main positioning unit 67 on the upper side of the battery cell 2, the aligning element 673 near the feeding end of the conveyor 34 rotates counterclockwise, while the aligning element 673 away from the feeding end of the conveyor 34 rotates clockwise, until the aligning wheel in the aligning element 673 is positioned away from the center of the conveyor 34, thus opening up. Similarly, in the main positioning unit 67 on the lower side of the battery cell 2, the aligning element 673 near the feeding end of the conveyor 34 rotates clockwise, while the aligning element 673 away from the feeding end of the conveyor 34 rotates counterclockwise, until the aligning wheel in the aligning element 673 is positioned away from the center of the conveyor 34, thus opening up. This ensures that a gap is left between the two main positioning units 67 in the second positioning assembly 64 for the battery cell 2 to pass through. At this time, the second guide wheel 664 slides on the first guide surface 674, causing the entire second auxiliary positioning unit 66 to move outward in a direction perpendicular to the first direction, compressing the second return spring 663. When cell 2 reaches between the two main positioning units 67, the positioning drive 671 in the second positioning assembly 64 is re-driven, causing the two sliding parts 672 to move away from each other. Under the principle of leverage, the aligning part 673 in the main positioning unit 67 on the upper side of cell 2, near the feeding end of the conveyor 34, rotates clockwise, and the aligning part 673 away from the feeding end of the conveyor 34 rotates counterclockwise, until the aligning wheel in the aligning part 673 is attached to the two smaller side surfaces of the cell that intersect with the first direction. Similarly, the aligning part 673 in the main positioning unit 67 on the lower side of cell 2, near the feeding end of the conveyor 34, rotates counterclockwise, and the aligning part 673 away from the feeding end of the conveyor 34 rotates clockwise, until the two aligning parts 673 are respectively attached to the two smaller side surfaces of the cell 2 that intersect with the axis of the first direction, thereby restricting the movement of cell 2 in the first direction. Simultaneously, as the two sliding members 672 move away from each other, the second guide wheel 664 moves diagonally downward on the second guide surface 675. At the same time, the second return spring 663 resets, causing the entire second auxiliary positioning unit 66 to move closer until the second clamping block 661 presses against the side surface of the battery cell 2, thus coordinating with the main positioning unit 67 to perform bidirectional positioning of the battery cell 2. At this time, the second positioning component 64 positions the side surface of the battery cell 2, exposing the upper surface, and the upper surface roughening processor 43 roughens the upper surface of the battery cell 2. The first conveying section 31 process is completed, processing the side surface and the top surface of the battery cell 2 formed by its length and height.

[0085] The flipping mechanism 1 is used to flip and move the battery cell 2 in the first state in the first conveying section 31 to the second state and place it on the second conveying section 32. The specific process is as follows: the sliding module 16 drives the lifting module 18 and the flipping mechanism 1 to slide back and forth along the first direction. The lifting module 18 is used to drive the flipping mechanism 1 to move vertically up and down. The sliding module 16 and the lifting module 18 are linked to drive the flipping mechanism 1 to approach the battery cell 2 in the first state that has been processed by the upper surface texturing processor 43, the front surface texturing processor 41 and the rear surface texturing processor 42 at the end of the first conveying section 31. The drive cylinder 122 drives the two grippers 121 to move away from each other until the distance between the two grippers 121 is greater than the length of the battery cell 2. The two grippers 121 form a clamping space. The sliding module 16 and the lifting module 18 work together to move the two grippers 121 to the two sides of the battery cell 2 that intersect in the first direction until the battery cell 2 is located in the clamping space. At this time, the clamping movement direction of the two grippers 121 is perpendicular to the first direction. The drive cylinder 122 drives the two grippers 121 to come closer to each other and fit against the two sides of the grippers 121 to clamp the battery cell 2 in the first posture of being placed vertically. The lifting module 18 is raised to make room for the flipping mechanism 1 to flip. The flipping drive 11 is activated and rotates 180 degrees counterclockwise or clockwise, so that the battery cell 2 is in the second posture of being placed horizontally on the reverse side. The sliding module 16 and the lifting module 18 work together to place the battery cell 2 in the second position onto the first pad 53 in the second conveying section 32. The drive cylinder 122 drives the two grippers 121 to move back toward each other, releasing the battery cell 2.

[0086] The first positioning component 61, the second positioning component 64, the front surface texturing processor 41, the rear surface texturing processor 42, and the upper surface texturing processor 43 on the second conveying section 32 process the battery cell 2 suitable for the second position. The processing steps are the same as those on the first conveying section 31, except that the main positioning unit 67 on the second conveying section 32 clamps the long side intersecting in the first direction, exposing the short side for texturing. This will not be elaborated further here. After the process in the second conveying section 32 is completed, the side surface formed by the width and height of the battery cell 2 and the reverse side opposite to the upper surface are processed.

[0087] With the above setup, the first positioning component 61 is used to match the front surface texturing processor 41 and the rear surface texturing processor 42, and the second positioning component 64 is used to match the upper surface texturing processor 43. After the battery cell 2 is transported to the texturing processing station via the conveyor line, the positioning components clamp and fix the battery cell 2, calibrate the position of the battery cell 2, and prevent the battery cell 2 from shaking during the texturing process, which would affect the texturing effect. The flipping mechanism 1 flips the battery cell 2 from the first state to the second state, and processes three of its surfaces on the first conveying section 31 and the other three surfaces on the second conveying section 32, thereby improving processing efficiency.

[0088] In other feasible embodiments, this invention can process multiple battery cells simultaneously. For example, two front surface texturing processors 41, two rear surface texturing processors 42, and two upper surface texturing processors 43 are provided on each of them. Two flipping drive members 11 are provided on the flipping mechanism 1. Two are provided on each of the first conveying section 31 and the second conveying section 32 along the first direction. This allows the entire battery cell texturing device to process multiple battery cells simultaneously, thereby improving work efficiency.

[0089] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
