Description

Technical Field

[0001] This application relates to the field of battery cell production equipment, specifically a battery cell straightening mechanism. Background Technology

[0002] A battery cell module is formed by stacking multiple battery cells. Before being stacked into a battery cell module, the battery cells need to undergo multiple processing steps. Currently, the battery cells are generally transported to each processing step in sequence via a conveyor line.

[0003] During the process of the battery cell being transported by the conveyor line, the battery cell may shift relative to the conveyor line due to imbalance or vibration of the conveyor line itself. Therefore, before unloading, the battery cell needs to be sized by a sizing mechanism to ensure that the battery cell is accurately clamped by the handling mechanism. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a cell alignment mechanism, the specific technical solution of which is as follows:

[0005] The cell alignment mechanism includes a base, a sliding seat, a first clamping plate, a second clamping plate, two rollers, a push plate, a transmission plate, a spring, and a driving component, wherein:

[0006] The sliding seat is slidably mounted on the base along a first direction, and the push plate is mounted on the end face of the sliding seat;

[0007] The first clamping plate and the second clamping plate are slidably mounted on the sliding seat along a second direction, which is perpendicular to the first direction on a horizontal plane. The two rollers are respectively mounted on the first clamping plate and the second clamping plate, and the two ends of the spring abut against the first clamping plate and the second clamping plate respectively.

[0008] The transmission plate is slidably mounted on the base along the first direction. The transmission plate has two waist-shaped holes, which are inclined outward from the middle of the transmission plate. The two rollers are respectively inserted into one of the waist-shaped holes. The driving member is mounted on the base and is used to drive the transmission plate to slide along the first direction.

[0009] In this application, when the driving component pushes the transmission plate to slide towards the battery cell in the first direction, the sliding seat, the first clamping plate, the second clamping plate, and the push plate all move closer to the battery cell along with the transmission plate. When the push plate abuts against the battery cell, the sliding seat can no longer slide forward. The push plate then pushes the battery cell along the first direction, achieving alignment of the battery cell in the first direction. At this time, the first and second clamping plates are located on opposite sides of the battery cell. The driving component continues to push the transmission plate closer to the battery cell, causing the transmission plate to slide relative to the sliding seat in the first direction. Through the cooperation of the oblong hole in the transmission plate and the rollers of the first and second clamping plates, the first and second clamping plates move closer together and clamp the battery cell, achieving alignment of the battery cell in the second direction. By using a single driving component to drive the push plate, the first clamping plate, and the second clamping plate to align the battery cell in the first and second directions respectively, the structure of the battery cell alignment mechanism is simplified, production costs are reduced, and the positional accuracy of the battery cell in both directions is ensured.

[0010] In some embodiments, a guide rod extending in a second direction is fixedly mounted on the first clamping plate, and a guide hole is provided on the second clamping plate for the guide rod to be inserted into, and the spring is sleeved on the guide rod.

[0011] The guide rod limits the spring to extend and retract only in the second direction. Before the push plate comes into contact with the battery cell, the first and second clamping plates are at their furthest positions under the push of the spring, so that the first and second clamping plates can slide to both sides of the battery cell in the first direction.

[0012] In some embodiments, the base is provided with two first slide rails extending along the first direction, and the sliding seat is slidably mounted on the two first slide rails by two sliders.

[0013] The sliding seat is slidably mounted on two first slide rails by two symmetrical sliders, which can keep the sliding seat stable when sliding in the first direction, reduce wear on individual sliders and first slide rails, and extend the service life of the mechanism.

[0014] In some embodiments, a limiting block is provided on the base between the two first slide rails, the limiting block being close to the end of the first slide rail away from the driving member, and the limiting block being located on the sliding path of the sliding seat.

[0015] When the pusher plate is pressed against the battery cell and a certain amount of force is applied, the sliding seat will press against the limit block, and the sliding seat will not be able to continue sliding in the first direction. This prevents the pusher plate from applying too much force to the battery cell, which could cause the battery cell to be damaged by the pusher plate.

[0016] In some embodiments, the sliding seat extends along the first direction with two extension plates, and a clearance space is formed between the two extension plates for the limiting block to pass through. The push plate is fixedly installed on the two extension plates, and a clearance notch for avoiding the limiting block is provided at the bottom end of the push plate.

[0017] By rationally arranging the positional relationship between the push plate, the sliding seat, and the limiting block, it is ensured that the push plate can pass over the limiting block and abut against the battery cell, while the limiting block can also limit the sliding seat.

[0018] In some embodiments, a first end plate is provided on the first clamping plate, and a second end plate is provided on the second clamping plate. The first end plate and the second end plate are disposed opposite to each other and are respectively located on both sides of the push plate. The push plate is perpendicular to the first end plate.

[0019] By replacing the first clamping plate and the second clamping plate with the first end plate and the second end plate to clamp the battery cell along the second direction, the contact area with the battery cell can be effectively increased, avoiding deformation of the battery cell after local pressure, thus protecting the battery cell.

[0020] In some embodiments, the sliding seat is provided with a second slide rail extending along the second direction, and the first clamping plate and the second clamping plate are respectively slidably mounted on the second slide rail by a slider.

[0021] By installing both the first and second clamping plates on the second slide rail, the moving reference of the first and second clamping plates is the same, ensuring the alignment of the first and second clamping plates and improving the clamping and regularity of the battery cell by the first and second clamping plates.

[0022] In some embodiments, a support block is provided on the base, a third slide rail is provided on the transmission plate, the first end of the third slide rail is fixedly mounted on the transmission plate, the second end of the third slide rail is slidably mounted on the support block along the first direction via a slider, and the driving component is mounted on the support block.

[0023] The cooperation of the third slide rail and the slider ensures that the transmission plate can only slide relative to the base in the first direction, preventing the transmission plate from shifting during movement and ensuring the accuracy of the transmission plate's movement.

[0024] To address the aforementioned technical problems, this application also provides a battery cell delivery device, the specific technical solution of which is as follows:

[0025] The battery cell conveying device includes a conveying line, a positioning element, and a battery cell straightening mechanism. The conveying line is used to convey battery cells along the second direction. The positioning element and the battery cell straightening mechanism are respectively located on both sides of the conveying line. The positioning element cooperates with the push plate to clamp the battery cell at a predetermined position on the conveying line.

[0026] After the conveyor line transports the battery cell to the predetermined position between the battery cell straightening mechanism and the positioning component, the drive component of the battery cell straightening mechanism drives the transmission plate, sliding seat, first clamping plate, second clamping plate, and push plate to move synchronously closer to the battery cell. When the push plate abuts against the first surface of the battery cell, the drive component continues to push the battery cell forward, causing the second surface of the battery cell to abut against the positioning component, thus completing the positioning of the battery cell in the first direction. At this time, the sliding seat and push plate are relatively stationary with respect to the battery cell. After the drive component continues to push the transmission plate forward, the first clamping plate and the second clamping plate will move closer to each other in the second direction and clamp the battery cell, thereby completing the positioning of the battery cell in the second direction. Subsequently, the drive component pulls the transmission plate away from the battery cell. After the first clamping plate and the second clamping plate lose the pushing force of the transmission plate, the spring separates the first clamping plate and the second clamping plate from each other in the second direction and detaches them from the battery cell. Then, the drive component pulls the transmission plate, sliding seat, first clamping plate, second clamping plate, and push plate away from the battery cell, and the conveyor line transports the straightened battery cell to the next process.

[0027] To address the aforementioned technical problems, this application also provides another cell delivery device, the specific technical solution of which is as follows:

[0028] The cell conveying device includes a conveying line and two sets of cell straightening mechanisms. The conveying line is used to convey cells along the second direction. The two sets of cell straightening mechanisms are located opposite each other on both sides of the conveying line. The push plates of the two sets of cell straightening mechanisms cooperate to clamp the cells at predetermined positions on the conveying line.

[0029] After the conveyor line transports the battery cell to a predetermined position between two sets of battery cell straightening mechanisms, the driving components of the two sets of mechanisms drive their corresponding transmission plates to move closer together in a first direction. Once the push plates of the two sets of straightening mechanisms are against the first and second surfaces of the battery cell, the battery cell is straightened in the first direction. The driving components of the two sets of straightening mechanisms continue to drive the corresponding transmission plates closer together, causing the two sets of first and second clamping plates to clamp the battery cell in the second direction, thus achieving automatic straightening of the battery cell in the second direction. By cooperating with each other, the two sets of straightening mechanisms achieve automated bidirectional straightening of the battery cell at the predetermined position, improving the positional accuracy of the battery cell.

[0039] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 and Figure 2 As shown, this application provides a cell alignment mechanism, including a base 1, a sliding seat 2, a first clamping plate 3, a second clamping plate 4, two rollers 31, a push plate 21, a transmission plate 5, a spring, and a driving member 6. The sliding seat 2 is slidably mounted on the base 1 along a first direction X, and the push plate 21 is mounted on the end face of the sliding seat 2. The first clamping plate 3 and the second clamping plate 4 are slidably mounted on the sliding seat 2 along a second direction Y, which is perpendicular to the first direction X on a horizontal plane. The two rollers 31 are respectively mounted on the first clamping plate 3 and the second clamping plate 4, and the two ends of the spring abut against the first clamping plate 3 and the second clamping plate 4, respectively. The transmission plate 5 is slidably mounted on the base 1 along the first direction X. The transmission plate 5 has two oblong holes 51, which are inclined outward from the middle of the transmission plate 5. The two rollers 31 are respectively inserted into one of the oblong holes 51. The driving member 6 is mounted on the base 1 and is used to drive the transmission plate 5 to slide along the first direction X.

[0041] Figure 1At this time, the transmission plate 5 is located away from the battery cell 9. When the driving component 6 pushes the transmission plate 5 to slide towards the battery cell 9 along the first direction X, the sliding seat 2, the first clamping plate 3, the second clamping plate 4, and the push plate 21 will all move closer to the battery cell 9 along with the transmission plate 5. When the push plate 21 is against the battery cell 9, the sliding seat 2 can no longer slide forward. With the help of the push plate 21, the battery cell 9 is pushed along the first direction X, thus achieving the alignment of the battery cell 9 in the first direction X. At this time, as Figure 2 As shown, the first clamping plate 3 and the second clamping plate 4 are located on both sides of the battery cell 9. The driving member 6 continues to push the transmission plate 5 closer to the battery cell 9, causing the transmission plate 5 to slide relative to the sliding seat 2 along the first direction X. With the help of the waist-shaped hole 51 of the transmission plate 5 and the cooperation of the rollers 31 of the first clamping plate 3 and the second clamping plate 4, the first clamping plate 3 and the second clamping plate 4 move closer to each other and clamp the battery cell 9 (see reference). Figure 2 This mechanism achieves the alignment of the battery cell 9 in the second direction Y. By using a single driving component 6 to drive the push plate 21, the first clamping plate 3, and the second clamping plate 4 to align the battery cell 9 in the first direction X and the second direction Y respectively, the structure of the battery cell alignment mechanism is simplified, production costs are reduced, and the positional accuracy of the battery cell 9 in the first direction X and the second direction Y is ensured.

[0042] When the transmission plate 5 is in Figure 1 When the distance between the two rollers 31 and the battery cell 9 is far, the two rollers 31 are located at the end of the oblong hole 51 that is tilted outwards, and the distance between the first clamping plate 3 and the second clamping plate 4 is the smallest at this time. When the transmission plate 5 is in the position of Figure 2 When the two rollers 31 are located near the battery cell 9, they are at the end of the waist-shaped hole 51 that is tilted inward. At this time, the distance between the first clamping plate 3 and the second clamping plate 4 is the farthest.

[0043] In some embodiments, such as Figure 3 As shown, a guide rod 32 extending along the second direction Y is fixedly installed on the first clamping plate 3, and a guide hole is opened on the second clamping plate 4 for the guide rod 32 to be inserted into. A spring is sleeved on the guide rod 32. The guide rod 32 limits the spring to only extend and retract along the second direction Y. Before the push plate 21 comes into contact with the battery cell 9, the first clamping plate 3 and the second clamping plate 4 are in the farthest position under the push of the spring, so that the first clamping plate 3 and the second clamping plate 4 can slide along the first direction X to both sides of the battery cell 9.

[0044] To avoid obstructing the guide rod 32, Figure 3 The spring is not shown in the figure. The spring selected in this application is a helical spring commonly used in the field. It is sufficient that the spring will contract along its own length direction after being subjected to force, and will rebound and reset along its own length direction after the external force is removed.

[0045] In some embodiments, the drive unit 6 is a cylinder, which can provide sufficient thrust to the transmission plate 5 and save equipment costs.

[0046] In some embodiments, such as Figure 3 As shown, the base 1 is provided with two first slide rails 11 extending along the first direction X, and the sliding seat 2 is slidably mounted on the two first slide rails 11 by two sliders.

[0047] The sliding seat 2 is slidably mounted on two first slide rails 11 by two symmetrical sliders, which can keep the sliding seat 2 stable when sliding in the first direction X, and reduce the wear on individual sliders and first slide rails 11, thus extending the service life of the mechanism.

[0048] In some embodiments, such as Figure 4 As shown, a limiting block 12 is provided on the base 1 between the two first slide rails 11. The limiting block 12 is located near the end of the first slide rail 11 away from the driving member 6, and the limiting block 12 is located on the sliding path of the sliding seat 2. When the push plate 21 abuts against the cell 9 and increases the pushing force to a certain extent, the sliding seat 2 will abut against the limiting block 12, and the sliding seat 2 will not be able to continue to slide along the first direction X, thus avoiding excessive pushing force applied by the push plate 21 to the cell 9, which could cause the cell 9 to be damaged by the push plate 21.

[0049] In some embodiments, such as Figure 4 and Figure 5 As shown, the sliding seat 2 extends along the first direction X with two extension plates 22, forming a clearance space between the two extension plates 22 for the limiting block 12 to pass through. The push plate 21 is fixedly installed on the two extension plates 22, and the bottom end of the push plate 21 has a clearance notch for the limiting block 12. By reasonably arranging the positional relationship of the push plate 21, the sliding seat 2, and the limiting block 12, it is ensured that the push plate 21 can pass over the limiting block 12 and abut against the battery cell 9, while also enabling the limiting block 12 to limit the sliding seat 2.

[0050] In some embodiments, such as Figure 4 As shown, a first end plate 33 is provided on the first clamping plate 3, and a second end plate 41 is provided on the second clamping plate 4. The first end plate 33 and the second end plate 41 are arranged opposite each other and are located on both sides of the push plate 21, with the push plate 21 being perpendicular to the first end plate 33. By using the first end plate 33 and the second end plate 41 instead of the first clamping plate 3 and the second clamping plate 4 to clamp the battery cell 9 along the second direction Y, the contact area with the battery cell 9 can be effectively increased, preventing the battery cell 9 from deforming due to local pressure, thus protecting the battery cell 9.

[0051] In some embodiments, such as Figure 3As shown, a second slide rail 23 extending along the second direction Y is provided on the sliding base 2. The first clamping plate 3 and the second clamping plate 4 are respectively slidably mounted on the second slide rail 23 via sliders. By mounting both the first clamping plate 3 and the second clamping plate 4 on the second slide rail 23, the moving reference of the first clamping plate 3 and the second clamping plate 4 is the same, ensuring the alignment of the first clamping plate 3 and the second clamping plate 4, and improving the clamping and regularity effect of the first clamping plate 3 and the second clamping plate 4 on the battery cell 9.

[0052] In some embodiments, such as Figure 2 As shown, a support block 14 is provided on the base 1, and a third slide rail 13 is provided on the transmission plate 5. The first end of the third slide rail 13 is fixedly installed on the transmission plate 5, and the second end of the third slide rail 13 is slidably installed on the support block 14 along the first direction X via a slider. The driving component 6 is installed on the support block 14. Through the cooperation of the third slide rail 13 and the slider, the transmission plate 5 can only slide relative to the base 1 along the first direction X, avoiding the transmission plate 5 from shifting during movement and ensuring the accuracy of the movement of the transmission plate 5.

[0053] like Figure 6 As shown, this application also provides a battery cell conveying device, including a conveying line 7, a positioning member 8, and a battery cell straightening mechanism. The conveying line 7 is used to convey battery cells 9 along the second direction Y. The positioning member 8 and the battery cell straightening mechanism are respectively located on both sides of the conveying line 7. The positioning member 8 cooperates with the push plate 21 to clamp the battery cell 9 at a predetermined position on the conveying line 7.

[0054] After the conveyor line 7 transports the battery cell 9 to the predetermined position between the battery cell straightening mechanism and the positioning member 8, the driving member 6 of the battery cell straightening mechanism drives the transmission plate 5, the sliding seat 2, the first clamping plate 3, the second clamping plate 4, and the push plate 21 to move closer to the battery cell 9 simultaneously. When the push plate 21 abuts against the first surface of the battery cell 9, the driving member 6 continues to push the battery cell 9 forward, causing the second surface of the battery cell 9 to abut against the positioning member 8, thus completing the position straightening of the battery cell 9 in the first direction X. At this time, the sliding seat 2 and the push plate 21 are relatively stationary with respect to the battery cell 9. After the driving member 6 continues to push the transmission plate 5 forward, the first clamping plate 3 and the second clamping plate 4 will move closer to each other in the second direction Y and clamp the battery cell 9, thereby completing the position straightening of the battery cell 9 in the second direction Y. Subsequently, the drive unit 6 pulls the transmission plate 5 away from the battery cell 9. After the first clamping plate 3 and the second clamping plate 4 lose the pushing force of the transmission plate 5, the spring separates the first clamping plate 3 and the second clamping plate 4 from each other along the second direction Y and detaches them from the battery cell 9. Then, the drive unit 6 pulls the transmission plate 5, the sliding seat 2, the first clamping plate 3, the second clamping plate 4 and the push plate 21 away from the battery cell 9. The conveyor line 7 transports the shaped battery cell 9 to the next process.

[0055] like Figure 7As shown, this application also provides another battery cell conveying device, including a conveying line 7 and two sets of battery cell straightening mechanisms. The conveying line 7 is used to convey battery cells 9 along the second direction Y. The two sets of battery cell straightening mechanisms are located opposite each other on both sides of the conveying line 7. The push plates 21 of the two sets of battery cell straightening mechanisms cooperate to clamp the battery cells 9 at predetermined positions on the conveying line 7.

[0056] After the conveyor line 7 transports the battery cell 9 to the predetermined position between the two battery cell straightening mechanisms, the driving components 6 of the two battery cell straightening mechanisms drive the corresponding transmission plates 5 to move closer to each other along the first direction X. When the push plates 21 of the two battery cell straightening mechanisms abut against the first and second surfaces of the battery cell 9, the battery cell 9 is straightened in the first direction X. The driving components 6 of the two battery cell straightening mechanisms continue to drive the corresponding transmission plates 5 to move closer to each other, so that the two sets of first clamping plates 3 and second clamping plates 4 clamp the battery cell 9 in the second direction Y, realizing the automatic straightening of the battery cell 9 in the second direction Y. By cooperating with each other, the two battery cell straightening mechanisms achieve automated bidirectional straightening of the battery cell 9 at the predetermined position, improving the positional accuracy of the battery cell 9.

[0057] In this application, the conveyor line 7 can be a belt conveyor line 7 or a plate chain conveyor line 7 commonly used in the art, and no special design is required.

[0058] The foregoing has provided a sufficiently detailed and specific description of this application. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within the protection scope of this application. The scope of protection claimed in this application is defined by the claims, not by the above descriptions in the embodiments. Furthermore, the embodiments mentioned in this application are not limited to a single implementation; some embodiments can also be combined.
