Description

Technical Field

[0001] The present application relates to the field of photovoltaic cell assembly production, and specifically to a cell string transport device. Background Art

[0002] When performing string welding of busbar-less cells, since there is no busbar on the busbar-less cells, the bonding force between the cells and the welding ribbon is poor after the cells are welded into a string, which can easily cause the welding ribbon to be partially or completely separated from the cells, affecting the normal production of the assembly. In order to ensure the connection strength between the cells and the welding ribbon, the commonly used solution is to apply glue to the cell string after the string connection is completed, so that the welding ribbon is bonded to the cells through the glue.

[0003] For battery strings with welding strips on both the upper and lower surfaces, it is necessary to apply glue to both sides of the battery cells. After the traditional battery string gluing equipment completes the gluing on the first surface of the battery string, the battery string is picked up and flipped 180° by a flipping mechanism, and then the flipping mechanism is used to drive the battery string to move under the gluing mechanism to apply glue on the second surface of the battery string (the surface facing away from the first surface). The flipping mechanism usually uses a suction cup or adsorption plate to adsorb the battery string, and is driven to translate by a linear module. On the one hand, it is difficult for the suction cup or adsorption plate to ensure the horizontal position of the battery string during the process of lifting the battery string for gluing. On the other hand, the battery string is easily shaken during the translation of the battery string driven by the linear module, thereby affecting the gluing accuracy and quality of the battery string.

[0004] In order to solve the above-mentioned problems existing in traditional battery string gluing equipment, a feasible solution is to convey the battery string to the bottom of the first gluing mechanism through the first conveyor line to implement first surface gluing, and then the battery string handling device picks up the battery cells that have completed the first surface gluing from the first conveyor line, and flips the battery string, and then transfers the flipped battery string to the second conveyor line, and conveys the battery string to the bottom of the second gluing mechanism through the second conveyor line to implement second surface gluing.

[0005] In the above solution, a battery string handling device is required to flip and transport the battery string. Common battery string handling devices usually include a battery string flipping mechanism and a battery string handling manipulator. Both the battery string flipping mechanism and the battery string handling manipulator are provided with suction cups. When in use, the flipping mechanism is first used to suck the battery string from the first conveyor line and flip the battery string, and then the battery string handling manipulator is used to suck the flipped battery string from the flipping mechanism and transport the flipped battery string to the second conveyor line.

[0006] When the battery string transport device is used to flip and transport the battery string, the battery string needs to be sucked and placed twice, which increases the risk of hidden cracks in the battery string. Utility Model Content

[0007] In view of the problems existing in the traditional battery string transport device, the present application provides a battery string transport device, and its detailed technical solution is as follows:

[0008] A battery string handling device includes a turning mechanism and a conveying mechanism, wherein:

[0009] The flipping mechanism is arranged along a first horizontal direction and is configured to absorb the battery string and flip the battery string;

[0010] The conveying mechanism is located above the flipping mechanism, and the flipping mechanism is also configured to lift the flipped battery string upward to above the conveying surface of the conveying mechanism;

[0011] The conveying mechanism is configured to receive the battery string on the turning mechanism when the turning mechanism descends, and to convey the battery string to a rear channel along a first horizontal direction.

[0012] The battery string handling device of the present application includes a flipping mechanism and a conveying mechanism. When in use, the flipping mechanism sucks the battery string and flips the battery string, then lifts the battery string upward and lowers it to the conveying surface of the conveying mechanism, and then the conveying mechanism conveys the flipped battery string backward. That is, the present application does not need to transfer the battery string on the flipping mechanism to the conveying mechanism through a battery string handling manipulator, thereby reducing the risk of hidden cracks in the battery cells. In addition, the flipping mechanism and the conveying mechanism are arranged up and down, which reduces the size of the battery string handling device.

[0013] In some embodiments, the flipping mechanism includes a lifting drive unit, a lifting frame, a flipping frame, a flipping drive unit and a suction assembly, wherein: the lifting frame is connected to the driving end of the lifting drive unit, the flipping frame is rotatably connected to the lifting frame, and the flipping frame is transmission-connected to the flipping drive unit disposed on the lifting frame; the suction assembly includes a plurality of suction cups disposed on the flipping frame at intervals along a first horizontal direction; the lifting drive unit is configured to drive the suction assembly to descend so that the suction assembly adsorbs the first surface of the battery string; the flipping drive unit is configured to drive the suction assembly to flip, so as to drive the battery string adsorbed on the suction assembly to flip, so that the second surface of the battery string facing away from the first surface faces upward; the lifting drive unit is also configured to drive the suction assembly to rise so as to lift the flipped battery string to above the conveying surface of the conveying mechanism, and drive the suction assembly to descend so that the battery string falls onto the conveying surface of the conveying mechanism.

[0014] The flipping mechanism is configured so that the flipping mechanism can absorb the battery string and then flip the battery string immediately, and place the flipped battery string on the conveying surface of the conveying mechanism by lifting and lowering.

[0015] In some embodiments, the suction assembly further includes a support plate, which is mounted on the flip frame along a first horizontal direction, and a plurality of suction cups pass through the support plate; after the plurality of suction cups absorb the battery string, the battery string rests on the support plate.

[0016] By providing a support plate, the battery string sucked by the suction cup is supported to prevent the battery cell and the welding ribbon from being pulled apart due to deformation of the suction cup.

[0017] In some embodiments, the suction component includes a first suction component and a second suction component, the suction surface of the first suction component and the suction surface of the second suction component are opposite to each other, and when the suction surface of the first suction component is flipped downward, the suction surface of the second suction component is flipped upward.

[0018] The first suction assembly and the second suction assembly alternately suck the battery string, and alternately flip the battery string and place it on the conveying surface of the conveying mechanism, thereby improving the flipping efficiency of the battery string.

[0019] In some embodiments, the conveying mechanism includes a fixed frame, an opening and closing mechanism, a first connecting frame, a second connecting frame, a first conveyor belt and a second conveyor belt, wherein: the opening and closing mechanism is arranged on the fixed frame; the first connecting frame and the second connecting frame are both slidably connected to the bottom of the fixed frame along the second horizontal direction, and are respectively connected to the opening and closing mechanism in a transmission manner, and the opening and closing mechanism is configured to drive the first connecting frame and the second connecting frame to slide apart to both sides or slide together to the middle along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction; the first conveyor belt is installed on the first connecting frame along the first horizontal direction, and the second conveyor belt is installed on the second connecting frame along the first horizontal direction, and the first conveyor belt is connected to the second connecting frame along the first horizontal direction. A lifting space is formed between the two conveyor belts for the turning mechanism to pass through; when the opening and closing mechanism drives the first connecting frame and the second connecting frame to slide apart on both sides, a lifting space with a first width is formed between the first conveyor belt and the second conveyor belt, and the first width is greater than the width of the battery string, and the turning mechanism lifts the flipped battery string to above the first conveyor belt and the second conveyor belt through the lifting space; when the opening and closing mechanism drives the first connecting frame and the second connecting frame to slide closer to the middle, a lifting space with a second width is formed between the first conveyor belt and the second conveyor belt, and the second width is less than the width of the battery string, and the turning mechanism descends through the lifting space, so that the battery string falls onto the first conveyor belt and the second conveyor belt.

[0020] By configuring the conveying mechanism, the flipping mechanism can lift the flipped battery string above the conveying surface of the conveying mechanism, and when the flipping mechanism descends to return to its original position, the battery string on the flipping mechanism automatically falls onto the conveying surface of the conveying mechanism.

[0021] In some embodiments, the battery string handling device also includes a first regularizing plate, a second regularizing plate, a first regularizing drive assembly and a second regularizing drive assembly, wherein: the first regularizing plate and the second regularizing plate are relatively arranged on both sides of the conveying mechanism, and the length directions of the first regularizing plate and the second regularizing plate are parallel to the first horizontal direction; the first regularizing drive assembly is installed on the first connecting frame and is driven and connected to the first regularizing plate, and the second regularizing drive assembly is installed on the second connecting frame and is driven and connected to the second regularizing plate; the first regularizing drive assembly and the second regularizing drive assembly are configured to drive the first regularizing plate and the second regularizing plate to move relative to each other along the second horizontal direction to push the sides of the battery strings carried on the first conveyor belt and the second conveyor belt to correct the position of the battery strings.

[0022] During the process of transferring the battery string from the flipping mechanism to the conveying mechanism, the battery cells therein may be misaligned. The first regularizing plate and the second regularizing plate, driven in cooperation with the first regularizing drive component and the second regularizing drive component, correct the position of the battery string to eliminate the misalignment between the battery cells and restore the alignment of all the battery cells in the battery string.

[0023] In some embodiments, the first regularizing plate includes a plurality of elastic plates spaced side by side, and the second regularizing plate is a rigid plate; after the second regularizing drive component drives the second regularizing plate to push the battery string, the first regularizing drive component drives the first regularizing plate to push the battery string.

[0024] The rigid second regularizing plate pushes the battery string first, and then the elastic first regularizing plate elastically presses against the battery string. After the regularization of the battery string is completed, the elastic first regularizing plate retreats first, and then the rigid second regularizing plate retreats. In this way, the regularization accuracy of the battery string can be improved.

[0025] In some implementations, at least one first inclined guide groove is provided on the first connecting frame, and an angle greater than 0° and less than 90° is formed between the first inclined guide groove and the second horizontal direction; at least one second inclined guide groove corresponding to the first inclined guide groove is provided on the second connecting frame, and the second inclined guide groove and the corresponding first inclined guide groove are symmetrical about the central axis of the lifting space; the opening and closing mechanism includes a translation drive assembly, a first connecting rod and a second connecting rod, wherein: the translation drive assembly is provided on the fixed frame; the first connecting rod is fixedly connected to the movable part of the translation drive assembly, and the first connecting rod is provided with a The first inclined guide grooves correspond to the first bearings one by one, and the first bearings are connected in the corresponding first inclined guide grooves and can slide along the first inclined guide grooves; the second connecting rod is fixedly connected to the movable part of the translation drive assembly, and the second connecting rod is provided with second bearings corresponding to the second inclined guide grooves one by one, and the second bearings are connected in the corresponding second inclined guide grooves and can slide along the second inclined guide grooves; the translation drive assembly is configured to drive the first connecting rod and the second connecting rod to translate back and forth along the first horizontal direction, so as to drive the first connecting frame and the second connecting frame to slide to both sides and separate or slide to the middle and approach each other along the second horizontal direction.

[0026] By configuring the first connecting frame, the second connecting frame and the opening and closing mechanism, the opening and closing mechanism can drive the first connecting frame and the second connecting frame to slide apart toward both sides or slide toward the middle along the second horizontal direction, and ensure that the movement amount of the first connecting frame and the second connecting frame is consistent, and finally ensure that the two side edges of the battery string fall onto the first conveyor belt and the second conveyor belt respectively.

[0028] Ensure that the first connecting rod and the second connecting rod slide stably to prevent the first connecting rod and the second connecting rod from getting stuck or deflected during the sliding process.

[0054] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] like Figures 1 to 3 As shown, the battery string transport device 3 in the embodiment of the present application includes a flipping mechanism 31 and a conveying mechanism 32, wherein:

[0056] The flipping mechanism 31 is arranged along a first horizontal direction (eg, the X-axis direction in the figure), and is configured to absorb the battery string and flip the battery string.

[0057] The conveying mechanism 32 is located above the flipping mechanism 31 , and the flipping mechanism 31 is further configured to lift the flipped battery string upward to above the conveying surface of the conveying mechanism 32 .

[0058] The conveying mechanism 32 is configured to receive the battery string on the turning mechanism 31 when the turning mechanism 31 descends, and to convey the battery string to a downstream path along a first horizontal direction.

[0059] It can be seen that in the battery string handling device in the embodiment of the present application, after the flipping mechanism 31 completes the flipping of the battery string, the battery string is lifted up and lowered to the conveying surface of the conveying mechanism 32, and then the conveying mechanism 32 conveys the flipped battery string backward. In other words, with the battery string handling device provided in the embodiment of the present application, there is no need to transfer the battery string on the flipping mechanism 31 to the conveying mechanism 32 by the battery string handling manipulator, thereby reducing the risk of hidden cracks in the battery cells. In addition, the flipping mechanism 31 and the conveying mechanism 32 are arranged up and down, thereby reducing the size of the battery string handling device.

[0060] The battery string transport device in the embodiment of the present application is suitable for use as a transport device for a battery string gluing device. Specifically, the flipping mechanism 31 is located above the first conveyor line, and the conveying mechanism 32 is docked with the second conveyor line. The flipping mechanism 31 picks up the battery string that has completed the first surface gluing from the first conveyor line, flips the battery string, and then lifts the flipped battery string to the conveying mechanism 32, which conveys the battery string to the second conveyor line, where the battery string completes the second surface gluing. It can be seen that the battery string transport device only performs one suction and placement of the battery string in the process of flipping and transporting the battery string on the first conveyor line to the second conveyor line, thereby reducing the risk of hidden cracks in the battery string.

[0061] like Figures 1 to 4 As shown, optionally, the flip mechanism 31 includes a lifting drive unit 311, a lifting frame 312, a flip frame 313, a flip drive unit 314 and a suction assembly 315, wherein: the lifting frame 312 is connected to the driving end of the lifting drive unit 311, the flip frame 313 is rotatably connected to the lifting frame 312, and the flip frame 313 is drivingly connected to the flip drive unit disposed on the lifting frame 312. The suction assembly 315 includes a plurality of suction cups spaced along the first horizontal direction on the flip frame.

[0062] The working process of the turnover mechanism 31 is:

[0063] The lifting driving unit 311 drives the suction component 315 to descend, so that the suction component 315 absorbs the first surface of the battery string.

[0064] Subsequently, the lifting drive unit 311 drives the suction assembly 315 to pick up the battery string, and the flipping drive unit 314 drives the suction assembly 315 to flip, so as to cause the battery string adsorbed on the suction assembly 315 to flip, so that the second surface of the battery string facing away from the first surface faces upward.

[0065] Next, the lifting drive unit 311 drives the suction assembly 315 to rise so as to lift the flipped battery string to above the conveying surface of the conveying mechanism 32 .

[0066] Finally, the lifting drive unit 311 drives the suction assembly 315 to descend and return to its original position, so that the battery string falls onto the conveying surface of the conveying mechanism 32 .

[0067] like Figure 4 As shown, optionally, the suction assembly 315 also includes a support plate 318, and the support plate 318 is installed on the flip frame 313 along the first horizontal direction, and a plurality of suction cups 317 pass through the support plate 318. After the plurality of suction cups 317 suck the battery string, the battery string is attached to the support plate 318. By providing the support plate 318, the battery string sucked by the suction cups 317 is supported, and the battery cell and the welding ribbon are prevented from being pulled off due to the deformation of the suction cups 317. In particular, for a battery cell without a main grid, the connection strength between the battery cell and the welding ribbon is relatively small. When the suction cup 317 adsorbs the battery cell and deforms, it is particularly easy to cause the battery cell and the welding ribbon to be pulled off. By providing the support plate, the pulling-off phenomenon can be effectively avoided.

[0068] Figure 4 In the illustrated embodiment, the support plate 318 is a split structure, which includes a plurality of support plates spaced apart along the first horizontal direction, each support plate corresponding to a battery cell in the battery string, and each support plate is provided with a suction cup 317. When a plurality of suction cups 317 adsorb the battery string, each battery cell in the battery string is supported on a corresponding support plate. Of course, the support plate 318 may also be a single strip plate extending along the first horizontal direction.

[0069] like Figure 4 As shown, the suction assembly 315 is provided in two groups, namely, the first suction assembly and the second suction assembly. The suction surface of the first suction assembly and the suction surface of the second suction assembly are opposite to each other. When the suction surface of the first suction assembly is flipped to face downward, the suction surface of the second suction assembly is flipped to face upward. In this way, the first suction assembly and the second suction assembly can alternately absorb the battery string, and alternately flip the battery string to the second surface facing upward and place it on the conveying surface of the conveying mechanism 32, thereby improving the flipping and transportation efficiency of the battery string.

[0070] like Figures 1 to 3 and Figures 5 to 7As shown, optionally, the conveying mechanism 32 includes a fixed frame 321, an opening and closing mechanism 322, a first connecting frame 323, a second connecting frame 324, a first conveyor belt 325 and a second conveyor belt 326, wherein the opening and closing mechanism 322 is arranged on the fixed frame 321. The first connecting frame 323 and the second connecting frame 324 are both slidably connected to the bottom of the fixed frame 321 along the second horizontal direction (such as the Y-axis direction in the figure), and are respectively connected to the opening and closing mechanism 322 in a transmission manner. The opening and closing mechanism 322 is configured to drive the first connecting frame 323 and the second connecting frame 324 to slide apart to both sides or slide close to the middle along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction. The first conveyor belt 325 is installed on the first connecting frame 323 along the first horizontal direction, and the second conveyor belt 326 is installed on the second connecting frame 324 along the first horizontal direction. A lifting space for the turning mechanism 31 to pass through is formed between the first conveyor belt 325 and the second conveyor belt 326. The upper surface of the first conveyor belt 325 and the upper surface of the second conveyor belt 326 constitute the conveying surface of the conveying mechanism 32 .

[0071] The cooperation process of the conveying mechanism 32 and the turning mechanism 31 is as follows:

[0072] The opening and closing mechanism 322 drives the first connecting frame 323 and the second connecting frame 324 to slide apart to both sides, so that a lifting space with a first width is formed between the first conveyor belt 325 and the second conveyor belt 326, and the first width is greater than the width of the battery string.

[0073] Subsequently, the flipping mechanism 31 lifts the flipped battery string through the lifting space to above the first conveyor belt 325 and the second conveyor belt 326. Since the width of the lifting space is greater than the width of the battery string, the battery string can pass through the lifting space upward and reach above the first conveyor belt 325 and the second conveyor belt 326.

[0074] Next, the opening and closing mechanism 322 drives the first connecting frame 323 and the second connecting frame 324 to slide toward the middle, so that a lifting space with a second width is formed between the first conveyor belt 325 and the second conveyor belt 326, and the second width is smaller than the width of the battery string.

[0075] Finally, the turning mechanism 31 descends to its position through the lifting space. Since the width of the lifting space is smaller than the width of the battery string, the two sides of the battery string are blocked by the first conveyor belt 325 and the second conveyor belt 326 respectively, and then fall onto the first conveyor belt 325 and the second conveyor belt 326.

[0076] It can be seen that during the process of transferring the battery string from the flipping mechanism 31 to the conveying mechanism 32 , there is no need to pick up the battery string, thereby preventing damage to the battery string.

[0077] When the battery string is transferred from the flip mechanism 31 to the conveying mechanism 32, the battery cells therein may be misaligned. To solve this problem, it is optional, such as Figure 8 As shown, the battery string handling device in the embodiment of the present application further includes a first regularization plate 33, a second regularization plate 34, a first regularization drive assembly 35, and a second regularization drive assembly 36, wherein: the first regularization plate 33 and the second regularization plate 34 are relatively arranged on both sides of the conveying mechanism 32, and the length direction of the first regularization plate 33 and the second regularization plate 34 is parallel to the first horizontal direction. The first regularization drive assembly 35 is installed on the first connecting frame 323 and connected to the first regularization plate 33, and the second regularization drive assembly 36 is installed on the second connecting frame 324 and is drivingly connected to the second regularization plate 36.

[0078] After the battery string is transferred to the conveying mechanism 32 by the flipping mechanism 31, the first regularization drive assembly 9 and the second regularization drive assembly 10 drive the first regularization plate 7 and the second regularization plate 4 to move relative to each other along the second horizontal direction to push the side edges of the battery string carried on the first conveyor belt 325 and the second conveyor belt 326, thereby completing the position correction of the battery string, thereby eliminating the misalignment between the battery cells and restoring the alignment of all the battery cells in the battery string.

[0079] Optionally, the first regularization plate 33 includes a plurality of elastic sheets arranged side by side and spaced apart, and the second regularization plate 34 is a rigid plate. After the second regularization drive assembly 36 drives the second regularization plate 34 to push the battery string, the first regularization drive assembly 35 drives the first regularization plate 33 to push the battery string.

[0080] When the battery string is transferred from the flip mechanism 31 to the conveying mechanism 32, the rigid second regularization plate 34 first pushes the battery string, and the elastic first regularization plate 33 then elastically presses against the battery string. After the regularization of the battery string is completed, the elastic first regularization plate 33 is first withdrawn, and the rigid second regularization plate 34 is then withdrawn, so that the regularization accuracy of the battery string can be improved.

[0081] like Figures 5 to 7 As shown, optionally, at least one first inclined guide groove 327 is provided on the first connecting frame 323, and an angle greater than 0° and less than 90° is formed between the first inclined guide groove 327 and the second horizontal direction. At least one second inclined guide groove 328 corresponding to the first inclined guide groove 327 is provided on the second connecting frame 324, and the second inclined guide groove 328 is symmetrical with the corresponding first inclined guide groove 327 about the central axis L of the lifting space.

[0082] Correspondingly, the opening and closing mechanism 322 includes a translation driving assembly 329, a first connecting rod 330 and a second connecting rod 331, wherein the translation driving assembly 329 is arranged on the fixed frame 321. The first connecting rod 330 is fixedly connected to the movable part of the translation driving assembly 329, and the first connecting rod 330 is provided with a first bearing 332 corresponding to the first inclined guide groove 327 one by one, and the first bearing 332 is inserted into the corresponding first inclined guide groove 327 and can slide along the first inclined guide groove 327. The second connecting rod 331 is fixedly connected to the movable part of the translation driving assembly 329, and the second connecting rod 331 is provided with a second bearing 333 corresponding to the second inclined guide groove 328 one by one, and the second bearing 333 is inserted into the corresponding second inclined guide groove 328 and can slide along the second inclined guide groove 328.

[0083] The translation driving assembly 329 is configured to drive the first connecting rod 330 and the second connecting rod 331 to translate back and forth along the first horizontal direction, thereby driving the first connecting frame 323 and the second connecting frame 324 to slide apart toward both sides or slide toward the middle along the second horizontal direction.

[0084] By configuring the first connecting frame 323, the second connecting frame 324 and the opening and closing mechanism 322, the opening and closing mechanism 322 can drive the first connecting frame 323 and the second connecting frame 324 to slide apart toward both sides or slide toward the middle along the second horizontal direction, and ensure that the movement amount of the first connecting frame 323 and the second connecting frame 324 is consistent, and finally ensure that the two side edges of the battery string fall onto the first conveyor belt 325 and the second conveyor belt 326 respectively.

[0085] Optionally, two first inclined guide grooves 327 are provided on the first connecting frame 323, and a first bearing 332 is provided at each end of the first connecting rod 330, and the two first bearings 332 are connected in a one-to-one correspondence in the two first inclined guide grooves 327. Two second inclined guide grooves 328 are provided on the second connecting frame 324, and a second bearing 333 is provided at each end of the second connecting rod 331, and the two second bearings 333 are connected in a one-to-one correspondence in the two second inclined guide grooves 328. Such a configuration can ensure that the first connecting rod 330 and the second connecting rod 331 slide stably, and prevent the first connecting rod 330 and the second connecting rod 331 from being stuck or deflected during the sliding process.

[0086] like Figure 7 As shown, optionally, the translation drive assembly 329 includes a driving member 334 and a driving plate 335, wherein the driving member 334 is mounted on the fixed frame 321, the driving plate 335 is connected to the driving end of the driving member 334, the first connecting rod 330 and the second connecting rod 331 are fixedly connected at both ends of the driving plate 335, and the driving member 334 drives the driving plate 335 to translate back and forth along the first horizontal direction, thereby driving the first connecting rod 330 and the second connecting rod 331 to translate synchronously along the first horizontal direction.

[0087] In addition, the opening and closing mechanism 322 further includes a first limiter 336 and a second limiter 337 which are arranged on the fixing frame 321 and located on both sides of the driving plate 335 . The driving member 334 drives the driving plate 335 to translate back and forth between the first limiter 336 and the second limiter 337 .

[0088] By setting the first limiter 336 and the second limiter 337, the movement stroke of the first connecting rod 330 and the second connecting rod 331 is limited. Finally, it is ensured that after the first connecting frame 323 and the second connecting frame 324 slide to both sides and separate into place, a lifting space with a first width is formed between the first conveyor belt 325 and the second conveyor belt 326. After the first connecting frame 323 and the second connecting frame 324 slide to the middle and close to place, a lifting space with a second width is formed between the first conveyor belt 325 and the second conveyor belt 326.

[0089] For example, Figure 7 In the illustrated embodiment, when the driving member 334 drives the driving plate 335 to translate toward the second stopper 337, the driving plate 335 finally abuts against the second stopper 337, so that a lifting space with a first width is formed between the first conveyor belt 325 and the second conveyor belt 326. When the driving member 334 drives the driving plate 335 to translate toward the first stopper 336, the driving plate 335 finally abuts against the first stopper 336, so that a lifting space with a second width is formed between the first conveyor belt 325 and the second conveyor belt 326.

[0090] Optionally, the first limiting member 336 and the second limiting member 337 have the same structure. Taking the first limiting member 336 as an example, it includes a limiting block and a limiting bolt, wherein: the limiting block is fixedly mounted on the fixing frame 321, the limiting block is provided with a screw hole extending along the first horizontal direction, the limiting bolt is screwed in the screw hole, and the limiting end of the limiting bolt points to the driving plate.

[0091] By screwing the limit bolt, the distance between the limit end of the limit bolt and the driving plate 335 can be adjusted, thereby implementing the adjustment of the moving stroke of the first connecting rod 330 and the second connecting rod 331, and finally achieving the adjustment of the first width and the second width, so that the battery string transport mechanism of the present application can achieve compatibility with battery strings of different widths.

[0092] like Figure 7 As shown, optionally, a slide rail extending along the second horizontal direction is further provided on the fixed frame 321, and the first connecting frame 323 and the second connecting frame 324 are respectively slidably connected to the slide rail via a slider. By providing the slide rail, the sliding guide of the first connecting frame 323 and the second connecting frame 324 is realized to prevent the first connecting frame 323 and the second connecting frame 324 from deviating.
