Technical Field
[0001] This application relates to the field of photovoltaic production equipment, specifically a solar cell straightening and conveying device. Background Technology
[0002] Before various processing steps are performed, the solar cells need to be positioned. The traditional positioning method is to set positioning components on both sides of the solar cell conveyor line. Positioning components may include positioning plates and driving mechanisms. Positioning plates are fixedly installed on the driving end of the driving mechanism. The driving mechanism drives the positioning plates to approach the solar cells to push the two sides of the solar cells and position them.
[0003] Traditional straightening methods involve clamping the solar cells from both sides. However, this method can easily damage thin and fragile solar cells. Utility Model Content
[0004] To address the aforementioned technical problems, this application provides a battery cell straightening and conveying device, the detailed technical solution of which is as follows:
[0005] A solar cell straightening and conveying device includes a conveying section, a first straightening section, and a second straightening section, wherein:
[0006] The conveying section is used to convey battery cells along a first direction, and a first regularization station and a second regularization station are formed on the conveying path of the conveying section;
[0007] The first aligning section is located on the first side of the conveying section at the first aligning station. The first aligning section is configured to move toward or away from the first aligning station in a second direction to push the battery cell at the first aligning station from the first side.
[0008] The second alignment section is located on the second side of the conveying section at the second alignment station. The second alignment section is configured to move toward or away from the second alignment station in a second direction to push the battery cells at the second alignment station from the second side.
[0009] The solar cell straightening and conveying device provided in this application first straightens the solar cells from a first side of the conveying section using a first straightening part, and then straightens them from a second side of the conveying section using a second straightening part. Ultimately, the two side edges of the solar cells are parallel to the conveying direction of the conveying section, and the centerline of the solar cells is aligned with the centerline of the conveying section. This single-sided straightening method ensures the straightening effect while avoiding damage to the solar cells.
[0010] In some embodiments, the first alignment section includes a first translation drive module, a first alignment frame, and a first alignment component, wherein: the first alignment frame is connected to a movable component of the first translation drive module, the first alignment frame extends along a first direction, the first alignment component is disposed on the first alignment frame, and the first alignment component includes a first alignment surface extending along the first direction; the first translation drive module is used to drive the first alignment frame to move toward or away from the first alignment station along a second direction, so as to drive the first alignment surface of the first alignment component to push the battery cell of the first alignment station from the first side.
[0011] When the first translation drive module drives the first alignment frame to move toward the battery cell located at the first alignment station, the first alignment component cooperates to push and align one side of the battery cell, and can make the center line of the battery cell located on the second side of the center line of the conveying section.
[0012] In some embodiments, the first alignment frame is adjustablely connected to the movable part of the first translation drive module.
[0013] The first alignment component will wear down after prolonged contact with the battery cells, leading to a decrease in alignment effectiveness. By adjusting the height of the first alignment frame, the worn parts of the first alignment component can be offset from the battery cells, while the unworn parts are used to align the battery cells, thus ensuring the alignment effect of the battery cells.
[0014] In some embodiments, the second alignment section includes a second translation drive module, a second alignment frame, and a second alignment member, wherein: the second alignment frame is connected to a movable component of the second translation drive module, the second alignment frame extends along a first direction, the second alignment member is disposed on the second alignment frame, and the second alignment member includes a second alignment surface extending along the first direction; the second translation drive module is used to drive the second alignment frame to move toward or away from the second alignment station along a second direction, so as to drive the second alignment surface of the second alignment member to push the battery cell of the second alignment station from the second side.
[0015] When the second translation drive module drives the second alignment frame to move toward the battery cell located at the second alignment station, the second alignment component cooperates to push and align the other side of the battery cell, and aligns the center line of the battery cell with the center line of the conveying section.
[0016] In some embodiments, the second alignment frame is adjustablely connected to the movable part of the second translation drive module.
[0017] The second alignment component will wear down after prolonged contact with the solar cells, leading to a decrease in alignment effectiveness. By adjusting the height of the second alignment frame, the worn parts of the second alignment component can be offset from the solar cells, thereby ensuring the alignment effect on the solar cells.
[0018] In some embodiments, the second translation drive module includes a first motor, a first guide rail, a first lead screw, a first nut, and a movable bracket, wherein: the first guide rail is arranged along a second direction, the movable bracket is slidably connected to the first guide rail, the first lead screw is arranged along the second direction and connected to the drive end of the first motor; the first nut is fixedly connected to the bottom of the movable bracket and screwed onto the first lead screw; the first motor is used to drive the first lead screw to rotate, so as to push the movable bracket to slide along the first guide rail via the first nut; and the second alignment frame is arranged on the movable bracket.
[0019] The second translation drive module is configured as a screw drive mechanism consisting of a first motor, a first guide rail, a first lead screw, a first nut, and a moving bracket. This mechanism enables slow and precise driving of the second alignment frame, thereby ensuring the alignment accuracy of the second alignment component on the other side of the battery cell. Ultimately, this aligns the centerline of the battery cell with the centerline of the conveying section.
[0020] In some embodiments, the second alignment part further includes a lifting bracket, an adjusting seat, and an adjusting bolt, wherein: the lifting bracket is slidably mounted on the movable bracket, and the second alignment bracket is disposed on the top of the lifting bracket; the adjusting seat is fixedly disposed on the movable bracket, and the upper end of the adjusting seat is provided with an adjusting screw hole; the adjusting bolt is arranged vertically, the upper end of the adjusting bolt is disposed on the lifting bracket, and the lower end of the adjusting bolt is screwed into the adjusting screw hole.
[0021] By turning the adjusting bolt, the lifting bracket can be pushed to slide up and down relative to the moving bracket, thereby adjusting the height of the second alignment bracket and the second alignment component, so that the wear part of the second alignment component is misaligned with the battery cell, ensuring the alignment effect of the second alignment component on the battery cell.
[0022] In some embodiments, a third sizing station is formed on the conveying path of the conveying unit, located after the second sizing station. The cell sizing conveying device also includes a third sizing part, which is disposed on both sides of the conveying unit at the third sizing station. The third sizing part is configured to size the cells located at the third sizing station in a first direction.
[0023] The third alignment section aligns the position of the solar cells in the first direction, ensuring that the front and rear edges of the solar cells are perpendicular to the conveying direction of the conveying section, and that the position of the solar cells in the first direction meets predetermined requirements.
[0024] In some embodiments, the third alignment section includes a third translation drive module, a first lifting drive module, a second lifting drive module, a third alignment frame, a fourth alignment frame, a plurality of third alignment components, and a plurality of fourth alignment components, wherein: the third translation drive module is located below the conveying section; the first lifting drive module is connected to the movable part of the third translation drive module; the third alignment frame is connected to the movable part of the first lifting drive module and located on the first side of the conveying section at the third alignment station; a plurality of third alignment components are spaced apart on the third alignment frame along a first direction, and the spacing between two adjacent third alignment components is greater than the width of the battery cell along the first direction; the second lifting drive module is connected to the movable part of the third translation drive module; and the fourth alignment frame is connected to the third translation drive module. On the moving parts of the second lifting drive module and located on the second side of the conveying section at the third alignment station, a plurality of fourth alignment components are spaced apart on the fourth alignment frame along the first direction. The fourth alignment components correspond one-to-one with the third alignment components, and the line connecting the fourth alignment component and the corresponding third alignment component is parallel to the second direction. The first lifting drive module and the second lifting drive module are configured to synchronously drive the third alignment frame and the fourth alignment frame to rise, so that the fourth alignment components and the corresponding third alignment components extend to the front or rear side of the battery cell at the third alignment station along the first direction. The third translation drive module is configured to drive the third alignment frame and the fourth alignment frame to translate along the first direction, so as to drive the fourth alignment components and the corresponding third alignment components to push the battery cell to be aligned in the first direction.
[0025] By configuring the third alignment section, it is possible to align the solar cells located at the third alignment station from both the front and rear sides, ensuring that the front and rear edges of the solar cells are perpendicular to the conveying direction of the conveying section. Furthermore, the third alignment section can also avoid obstructing the movement of the solar cells, allowing them to be smoothly conveyed to and from the third alignment station.
[0026] The conveying section is equipped with a preheating component, which is configured to preheat the conveying surface of the conveying section and the battery cells thereon.
[0027] In some applications, after the solar cells are aligned, film strips need to be stacked at the edges of the cells to form a battery cell. The cells are preheated by a preheating device, and the film strips become sticky due to the heat, thus adhering to the cells to form an integrated battery cell.
[0028] In some embodiments, the third alignment section further includes a third lifting drive module, a fourth lifting drive module, a first heating plate, and a second heating plate, wherein: the third lifting drive module is disposed on a movable component of the third translation drive module, the first heating plate is connected to the movable component of the third lifting drive module and located on the first side of the third alignment station, and the third lifting drive module is used to drive the first heating plate to rise to heat the first side edge of the battery cell located at the third alignment station; the fourth lifting drive module is disposed on a movable component of the third translation drive module, the second heating plate is connected to the movable component of the fourth lifting drive module and located on the second side of the third alignment station, and the fourth lifting drive module is used to drive the second heating plate to rise to heat the second side edge of the battery cell located at the third alignment station.
[0029] The first and second edges of the battery cell protrude outside the conveying section. During the movement of the battery cell on the conveying section, the conveying section does not heat the first and second edges of the battery cell properly. By setting the first heating plate and the second heating plate, the first and second edges of the battery cell can be heated, so that the entire battery cell is heated. This ensures that the film strips stacked on the edge of the battery cell are firmly bonded to the battery cell after being heated. Attached Figure Description

[0064] 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.
[0065] As described in the background section, traditional cell straightening methods use a clamping method from both sides to straighten the cells. For thin and fragile cells, this clamping method can easily cause damage. Therefore, this application provides a cell straightening and conveying device.
[0066] like Figure 1 As shown, the battery cell straightening and conveying device of this application includes a conveying section 1, a first straightening section 2, and a second straightening section 3, wherein:
[0067] The conveying unit 1 is used to convey battery cells along a first direction (such as the X direction), and a first aligning station A and a second aligning station B are formed on the conveying path of the conveying unit 1.
[0068] The first straightening section 2 is disposed on the first side of the conveying section 1 at the first straightening station A. The first straightening section 2 is configured to move toward or away from the first straightening station A in a second direction to push the battery cell of the first straightening station A from the first side.
[0069] The second straightening section 3 is disposed on the second side of the conveying section 1 at the second straightening station B. The second straightening section 3 is configured to move toward or away from the second straightening station B along a second direction (such as the Y direction) to push the battery cell at the second straightening station B from the second side.
[0070] like Figure 7 As shown, the optional operating process of the solar cell straightening and conveying device of this application is as follows:
[0071] Before being transported to the first straightening station A, there is an angle between the center line a of the battery cell 100 and the center line b of the transport section 1, that is, the two side edges (first side edge 101 and second side edge 102) of the battery cell 100 are inclined relative to the transport direction of the transport section 1.
[0072] The conveying unit 1 conveys the battery cell 100 in a step-by-step manner. When the battery cell 100 is conveyed to the first straightening station A, the battery cell 100 is paused. Subsequently, the first straightening unit 2 pushes the first side edge of the straightening battery cell 100 from the first side, so that the center line a of the battery cell 100 is located on the second side of the center line b of the conveying unit 1.
[0073] When the conveying unit 1 continues to convey the battery cell 100 to the second straightening station B, the battery cell 100 is paused. Subsequently, the second straightening unit 3 pushes the straightened battery cell 100 from the second side until the center line a of the battery cell 100 is aligned with the center line b of the conveying unit 1. During this process, the two side edges of the battery cell 100 are parallel to the conveying direction of the conveying unit 1.
[0074] The battery cell straightening and conveying device of this application first straightens the battery cell 100 from the first side of the conveying section 1 via the first straightening part 2, and then straightens the battery cell 100 from the second side of the conveying section 1 via the second straightening part 3. Ultimately, the two side edges of the battery cell 100 are parallel to the conveying direction of the conveying section 1, and the centerline of the battery cell is aligned with the centerline of the conveying section 1. This single-sided straightening method ensures the straightening effect while avoiding damage to the battery cell.
[0075] like Figure 2 As shown, optionally, the first alignment section 2 includes a first translation drive module 21, a first alignment frame 22, and a first alignment component 23, wherein: the first alignment frame 22 is connected to a movable part of the first translation drive module 21, the first alignment frame 22 extends along a first direction, the first alignment component 23 is disposed on the first alignment frame 22, and the first alignment component 23 includes a first alignment surface extending along the first direction. The first translation drive module 21 is used to drive the first alignment frame 22 to move toward or away from the first alignment station A along a second direction, so as to drive the first alignment surface of the first alignment component 23 to push the battery cell 100 of the first alignment station A from the first side. Specifically, when the first translation drive module 21 drives the first alignment frame 22 to move toward the battery cell 100 located at the first alignment station A, the first alignment component 23 cooperates to push one side of the battery cell 100 until the centerline of the battery cell 100 is located on the second side of the centerline of the conveying section 1.
[0076] Figure 2 In the embodiment shown, the first translation drive module 21 is a cylinder. Of course, the first translation drive module 21 can also be a linear drive module with other existing structures such as a motor and a lead screw and nut mechanism.
[0077] Figure 2 In the illustrated embodiment, the first aligning element 23 is a plurality of aligning rollers. Of course, the first aligning element 23 can also be a aligning block, aligning rod, or other aligning element with different structures. When the first aligning element 23 is a plurality of aligning rollers, the plurality of aligning rollers are arranged at intervals along a first direction, with their center lines arranged vertically. A plane that is tangent to the outer peripheral surfaces of all the aligning rollers simultaneously forms a first aligning surface, and the first aligning surface faces the conveying unit 1. When the first aligning element 23 is a aligning block or aligning rod, the first aligning surface is the side surface of the aligning block or aligning rod facing the conveying unit 1.
[0078] The first alignment component 23 will wear down after prolonged contact with the battery cell 100, resulting in a decrease in its alignment effect on the battery cell 100. To solve this problem, optionally, the first alignment frame 22 can be adjusted and height-adjusted to the moving part of the first translation drive module 21.
[0079] When significant wear occurs at the part of the first alignment component 23 that contacts the battery cell 100, affecting the alignment effect, the height of the first alignment frame 22 can be adjusted to offset the worn part from the battery cell 100, thereby ensuring the alignment effect of the first alignment component 23 on the battery cell 100.
[0080] Figure 3 In the illustrated embodiment, the second alignment section 3 includes a second translation drive module 31, a second alignment frame 32, and a second alignment component 33. The second alignment frame 32 is connected to a movable component of the second translation drive module 31 and extends along a first direction. The second alignment component 33 is disposed on the second alignment frame 32 and includes a second alignment surface extending along the first direction. The second translation drive module 31 drives the second alignment frame 32 to move towards or away from the second alignment station B along a second direction, thereby causing the second alignment surface of the second alignment component 33 to push the battery cell 100 at the second alignment station B from the second side. Specifically, when the second translation drive module 31 drives the second alignment frame 32 to move towards the battery cell 100 located at the second alignment station B, the second alignment surface of the second alignment component 33 cooperates to push and align the other side of the battery cell 100, aligning the centerline of the battery cell 100 with the centerline of the conveying section 1.
[0081] Similar to the first standard part 23, Figure 3 In the embodiment shown, the second aligning element 33 can also be multiple aligning rollers. Of course, the second aligning element 33 can also be aligning blocks, aligning rods, or other aligning elements.
[0082] Similarly, the second alignment member 33 will wear down after prolonged contact with the battery cell 100, resulting in a decrease in its alignment effect on the battery cell 100. To solve this problem, optionally, the second alignment frame 32 can be vertically and adjustablely connected to the moving part of the second translation drive module 31.
[0083] When significant wear occurs at the part of the second alignment member 33 that contacts the battery cell 100, affecting the alignment effect, the height of the second alignment frame 32 can be adjusted so that the worn part is offset from the battery cell 100, thereby ensuring the alignment effect of the second alignment frame 32 on the battery cell 100.
[0084] like Figure 3As shown, optionally, the second translation drive module 31 includes a first motor 311, a first guide rail 312, a first lead screw 313, a first nut 314, and a moving bracket 315, wherein: the first guide rail 312 is arranged along a second direction, the moving bracket 315 is slidably connected to the first guide rail 312, and the first lead screw 313 is arranged along the second direction and connected to the drive end of the first motor 311. The first nut 314 is fixedly connected to the bottom of the moving bracket 315 and screwed onto the first lead screw 313. The first motor 311 is used to drive the first lead screw 313 to rotate, so as to push the moving bracket 315 to slide along the first guide rail 312 via the first nut 314. The second alignment frame 32 is arranged on the moving bracket 315.
[0085] The second translation drive module 31 is configured as a screw drive mechanism consisting of a first motor 311, a first guide rail 312, a first lead screw 313, a first nut 314 and a moving bracket 315. This mechanism can achieve slow and precise drive of the second straightening frame 32, thereby improving the straightening accuracy of the second straightening component 33 on the other side of the battery cell, and ultimately ensuring that the center line of the battery cell is aligned with the center line of the conveying unit 1.
[0086] Of course, the second translation drive module 31 can also adopt other existing linear drive modules, such as cylinders, electric cylinders, etc.
[0087] like Figure 3 As shown, optionally, the second alignment section 3 also includes a lifting bracket 34, an adjusting seat 35, and an adjusting bolt 36, wherein: the lifting bracket 34 is slidably mounted on the movable bracket 315, and the second alignment frame 32 is located on top of the lifting bracket 34. The adjusting seat 35 is fixedly mounted on the movable bracket 315, and an adjusting screw hole is provided at the upper end of the adjusting seat 35. The adjusting bolt 36 is arranged vertically, with its upper end mounted on the lifting bracket 34 and its lower end screwed into the adjusting screw hole.
[0088] By turning the adjusting bolt 36, the lifting bracket 34 can be pushed to slide up and down relative to the moving bracket 315, thereby realizing the height adjustment of the second alignment bracket 32 and the second alignment component 33, so that the wear part of the second alignment component 33 is misaligned with the battery cell, and ultimately ensuring the alignment effect of the second alignment component 33 on the battery cell.
[0089] It should be noted that the structures of the first straightening part 2 and the second straightening part 3 in the battery cell straightening and conveying device of this application may be different. For example, the first straightening part 2 is... Figure 2 In the regularized structure shown in the embodiment, the second regularized part 3 is Figure 3 The regularization mechanism in the illustrated embodiment. The structures of the first regularization part 2 and the second regularization part 3 can also be the same; for example, both the first regularization part 2 and the second regularization part 3 are... Figure 2The regularization mechanism in the illustrated embodiment, for example, the first regularization part 2 and the second regularization part 3 are both Figure 3 The regularization mechanism in the illustrated embodiment.
[0090] like Figure 1 As shown, optionally, a third alignment station C is formed on the conveying path of the conveying unit 1, located after the second alignment station B. The cell alignment conveying device also includes a third alignment unit 4, which is disposed on both sides of the conveying unit 1 at the third alignment station C. The third alignment unit 4 is configured to align the cell 100 located at the third alignment station C in a first direction, thereby ensuring that the front and rear edges of the cell 100 are perpendicular to the conveying direction of the conveying unit 1, and that the position of the cell 100 in the first direction meets predetermined requirements.
[0091] like Figures 4 to 6 As shown, optionally, the third alignment section 4 includes a third translation drive module 41, a first lifting drive module 42, a second lifting drive module 43, a third alignment frame 44, a fourth alignment frame 45, a plurality of third alignment components 46, and a plurality of fourth alignment components 47, wherein:
[0092] The third translation drive module 41 is located below the conveying section 1. The first lifting drive module 42 is connected to the movable part of the third translation drive module 41. The third alignment frame 44 is connected to the movable part of the first lifting drive module 42 and is located on the first side of the conveying section 1 at the third alignment station. A plurality of third alignment components 46 are spaced apart on the third alignment frame 44 along the first direction. The distance between two adjacent third alignment components 46 is greater than the width of the battery cell 100 along the first direction.
[0093] The second lifting drive module 43 is connected to the movable part of the third translation drive module 41. The fourth alignment frame 45 is connected to the movable part of the second lifting drive module 43 and is located on the second side of the third alignment station along the conveying part 1. A plurality of fourth alignment parts 47 are spaced apart on the fourth alignment frame 45 along the first direction. The fourth alignment parts 47 correspond one-to-one with the third alignment parts 46. The line connecting the fourth alignment parts 47 and the corresponding third alignment parts 46 is parallel to the second direction.
[0094] like Figure 6 As shown, the optional conditioning process for the third conditioning section 4 of the solar cells 100 is as follows:
[0095] In the initial state, each of the third guide member 46 and the fourth guide member 47 is in a low position to avoid obstacles, that is, the height of the third guide member 46 and the fourth guide member 47 is lower than the height of the conveying surface of the conveying unit 1.
[0096] Waiting for several (for example) Figure 1When the three battery cells 100 are transported to the third alignment station C, the first lifting drive module 42 and the second lifting drive module 43 simultaneously drive the third alignment frame 44 and the fourth alignment frame 45 to rise, so that the fourth alignment component 47 and the corresponding third alignment component 46 extend to the front or rear side of the battery cell 100 at the third alignment station C along the first direction.
[0097] Subsequently, the third translation drive module 41 drives the third alignment frame 44 and the fourth alignment frame 45 to translate along the first direction, so as to drive the fourth alignment component 47 and the corresponding third alignment component 46 to push the battery cell 100 to be aligned in the first direction.
[0098] It can be seen that by setting the third straightening section 4, the third straightening section 4 can straighten the battery cell 100 located at the third straightening station C from the front and rear sides, so that the front and rear edges of the battery cell 100 are perpendicular to the conveying direction of the conveying section 1, and the position of the battery cell 100 in the first direction meets the predetermined requirements.
[0099] In addition, the third straightening unit 4 can also avoid the solar cell 100, so that the solar cell 100 can be smoothly transported to the third straightening station C, and the straightened solar cell can be smoothly transported out of the third straightening station C.
[0100] like Figure 4 As shown, optionally, the third translation drive module 41 includes a second motor 411, a second guide rail 412, a second lead screw 413, a second nut 414, and a movable seat 415, wherein: the second guide rail 412 is arranged along a first direction, the movable seat 415 is slidably connected to the second guide rail 412, and the second lead screw 413 is arranged along the first direction and connected to the drive end of the second motor 411. The second nut 414 is fixedly connected to the bottom of the movable seat 415 and screwed onto the second lead screw 413. The second motor 411 is used to drive the second lead screw 413 to rotate, so as to push the movable seat 415 to slide along the second guide rail 412 via the second nut 414. The first lifting drive module 42 and the second lifting drive module 43 are arranged on the movable seat 415.
[0101] By configuring the third translation drive module 41 as a screw drive mechanism consisting of a second motor 411, a second guide rail 412, a second lead screw 413, a second nut 414, and a moving seat 415, a slow and precise drive is implemented for the third alignment frame 44 and the fourth alignment frame 45, thereby improving the alignment accuracy of the third alignment component 46 and the fourth alignment component 47 for the battery cells in the first direction.
[0102] Optionally, the second lifting drive module 43 has the same structure as the first lifting drive module 42. Taking the first lifting drive module 42 as an example, it includes a cylinder 421 and a support base 422, wherein the third aligning frame 44 is mounted on the support base 422. The cylinder 421 is mounted on the movable base 415, and the cylinder 421 is connected to the support base 422 in a transmission manner. The cylinder 421 is used to drive the support base 422 and the third aligning frame 44 to lift.
[0103] Of course, the first lifting drive module 42 and the second lifting drive module 43 can also adopt other existing linear drive modules, as long as they can drive the third aligning frame 44 and the fourth aligning frame 45 to lift.
[0104] Optionally, the conveying section 1 is provided with a preheating component, which is configured to preheat the conveying surface of the conveying section 1 and the battery cells 100 thereon.
[0105] In some applications, after the solar cells 100 are aligned, film strips need to be stacked onto the edges of the solar cells 100 to form a battery cell. The solar cells 100 on the conveyor section 1 are preheated by a preheating device, causing the film strips to become adhesive and adhere to the solar cells 100, thus forming an integrated battery cell. The conveyor section 1 can be a conveyor belt, and the preheating device includes a preheating plate attached to the underside of the conveyor belt, with heating elements such as heating rods or heating wires embedded in the preheating plate.
[0106] like Figures 5 to 6 As shown, optionally, the third alignment section 4 also includes a third lifting drive module 48, a fourth lifting drive module 49, a first heating plate 410, and a second heating plate 420, wherein:
[0107] The third lifting drive module 48 is mounted on the movable part of the third translation drive module 41. The first heating plate 410 is connected to the movable part of the third lifting drive module 48 and is located on the first side of the third straightening station C. The third lifting drive module 48 is used to drive the first heating plate 410 to rise so as to heat the first side edge of the battery cell 100 located in the third straightening station C.
[0108] The fourth lifting drive module 49 is mounted on the movable part of the third translation drive module 41. The second heating plate 420 is connected to the movable part of the fourth lifting drive module 49 and is located on the second side of the third straightening station C. The fourth lifting drive module 49 is used to drive the second heating plate 420 to rise so as to heat the second side edge of the battery cell 100 located in the third straightening station C.
[0109] Optionally, the third lifting drive module 48 is a cylinder, electric cylinder, or other linear motion module. The third lifting drive module 48 is mounted on the movable seat 415. The first heating plate 410 is a horizontal strip plate, and the length direction of the first heating plate 410 extends along the first direction so that the first heating plate 410 can simultaneously contact and heat the lower surface of the first side edge of all the battery cells 100 at the third alignment station C. The first heating plate 410 is provided with a heating rod or other heating element inside. To ensure that the first heating plate 410 lifts and lowers smoothly, one end of the first heating plate 410 is connected to a vertical first support plate 430. The first support plate 430 and the movable seat 415 are connected by a first linear guide pair. The first linear guide pair is arranged vertically to guide the lifting and lowering of the first heating plate 410.
[0110] Similarly, the fourth lifting drive module 49 can also be a cylinder, an electric cylinder, or other linear motion module. The fourth lifting drive module 49 is mounted on the moving seat 415. The second heating plate 420 is a horizontal strip plate, and the length direction of the second heating plate 420 extends along the first direction so that the second heating plate 420 can simultaneously contact and heat the lower surface of the second side edge of all the battery cells 100 at the third straightening station C. The second heating plate 420 is equipped with a heating rod or other heating element inside. To ensure that the second heating plate 420 lifts and lowers smoothly, one end of the second heating plate 420 is connected to a vertical second support plate 440. The second support plate 440 and the moving seat 415 are connected by a second linear guide pair. The second linear guide pair is arranged vertically to guide the lifting and lowering of the second heating plate 420.
[0111] Specifically, in the initial state, the first heating plate 410 and the second heating plate 420 are in a low position to avoid obstacles, that is, the first heating plate 410 and the second heating plate 420 are lower than the height of the conveying surface of the conveying unit 1.
[0112] After the battery cell 100 is conveyed to the third straightening station C and straightened, the third lifting drive module 48 drives the first heating plate 410 to rise, so that the first heating plate 410 is close to the first side edge of the battery cell 100. At the same time, the fourth lifting drive module 49 drives the first heating plate 410 to rise, so that the second heating plate 420 is close to the second side edge of the battery cell 100.
[0113] To facilitate the straightening of the third straightening section 4, the first and second edges of the battery cell 100 protrude beyond the conveying section 1. During the movement of the battery cell 100 on the conveying section 1, the conveying section 1 does not heat the first and second edges of the battery cell 100 properly. By setting the first heating plate 410 and the second heating plate 420, the first and second edges of the battery cell 100 can be heated, so that the entire battery cell 100 is heated, thereby ensuring that the film strips stacked on the edge of the battery cell 100 are firmly bonded to the battery cell 100 after being heated.
