Description

Technical Field

[0001] This application relates to the field of photovoltaic production equipment, specifically a wafer picking and conveying mechanism and a wafer feeding device. Background Technology

[0002] The stringing machine can receive solar cells from baskets. Generally, a conveyor mechanism is inserted into the basket to remove the vertically stacked solar cells. Then, a transport mechanism moves the solar cells from the conveyor mechanism to the loading station of the stringing machine, where the stringing machine processes the solar cells into strings.

[0003] Existing battery strings are sometimes formed by connecting whole battery cells, and sometimes by connecting half battery cells. Correspondingly, flower baskets are divided into half-filler baskets and whole-filler baskets. A half-filler basket contains a column of left half cells and a column of right half cells, and is generally supported by three sets of spaced-apart support rods to support two columns of half cells simultaneously. A whole-filler basket, on the other hand, uses two sets of spaced-apart support rods to support a single column of whole cells.

[0004] Because of the obstruction of a set of support rods in the middle of the half-basket, and because the conveying mechanism needs to extend into the basket to retrieve the battery cells, the support rods in the middle of the half-basket will prevent the conveying mechanism adapted to the full basket from extending into the half-basket, causing the cell retrieval conveying mechanism adapted to the full basket to be unable to match the half-basket. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a solar cell picking and conveying device, the detailed technical solution of which is as follows:

[0006] A film picking and conveying mechanism, characterized in that the film picking and conveying mechanism includes a base, a first mounting plate, a second mounting plate, a first sliding plate, a second sliding plate, a first drive module, a first pulley assembly, a first conveyor belt, a second pulley assembly, a second conveyor belt, and a second drive module, wherein:

[0007] The first mounting plate and the second mounting plate are spaced apart on the base along the first direction, and are both adjustablely connected to the base along the first direction.

[0008] The first sliding plate is slidably connected to the first mounting plate, the second sliding plate is slidably connected to the second mounting plate, and the first driving module is disposed on the first mounting plate and the second mounting plate. The first driving module is used to drive the first sliding plate and the second sliding plate to slide synchronously along the second direction, which is perpendicular to the first direction.

[0009] The first pulley assembly is at least partially mounted on the first sliding plate. The first conveyor belt is fitted along the second direction on the movable parts of the first pulley assembly and the second drive module. The second pulley assembly is at least partially mounted on the second sliding plate. The second conveyor belt is fitted along the second direction on the movable parts of the second pulley assembly and the second drive module. The second drive module is used to drive the first conveyor belt and the second conveyor belt to synchronously convey the battery cells along the second direction.

[0010] By adjusting the positions of the first mounting plate and the second mounting plate on the base, so that the distance between the first mounting plate and the second mounting plate is adjusted to the first distance, the first conveyor belt and the second conveyor belt are respectively used to carry and transport one and a half battery cells.

[0011] By adjusting the positions of the first mounting plate and the second mounting plate on the base, so that the distance between the first mounting plate and the second mounting plate is adjusted to a second distance, the first conveyor belt and the second conveyor belt are used to cooperate in carrying and conveying a whole battery cell, wherein the second distance is smaller than the first distance.

[0012] The wafer-retrieving conveyor mechanism provided in this application allows for adjustment of the distance between a first mounting plate for mounting a first conveyor belt and a second mounting plate for mounting a second conveyor belt. When it is necessary to retrieve a half-cell from a half-cell basket, adjusting the distance between the first and second mounting plates to a larger first distance allows the first and second conveyor belts to extend into the two storage bins of the half-cell basket, retrieving two half-cells simultaneously each time. When it is necessary to retrieve a whole-cell from a full-cell basket, adjusting the distance between the first and second mounting plates to a smaller first distance allows the first and second conveyor belts to extend into the storage bin of the full-cell basket simultaneously, retrieving one whole-cell at a time. Therefore, the wafer-retrieving conveyor mechanism provided in this application achieves compatibility with both full-cell and half-cell basket retrieval.

[0013] In some embodiments, the second mounting plate and the first mounting plate are connected to the base in the same way. The base is provided with a waist-shaped hole extending in a first direction, and the first mounting plate is provided with a screw hole communicating with the waist-shaped hole. The first mounting plate is screwed onto the base by bolts passing through the waist-shaped hole and the screw hole.

[0014] An adjustable mounting method for a simple first mounting plate and a second mounting plate is provided. Taking the first mounting plate as an example, when it is necessary to adjust the mounting position of the first mounting plate in the first direction, first loosen the bolts, then push the first mounting plate to slide along the oblong hole. After sliding into place, tighten the bolts again to fix the first mounting plate to the base.

[0015] In some embodiments, the first drive module includes a first motor, a fixed plate, a support shaft, a drive pulley, a driven pulley, a belt, and a drive slider, wherein: the first motor is detachably mounted on the fixed plate, the fixed plate is detachably mounted on a first mounting plate or a second mounting plate, the drive pulley is connected to the drive end of the first motor; the driven pulley is rotatably mounted on the support shaft, the support shaft is detachably mounted on the first mounting plate or the second mounting plate along a first direction; the belt is fitted onto the drive pulley and the driven pulley along a second direction, the belt being located between the first mounting plate and the second mounting plate; the drive slider is connected to one side of the belt body, and both ends of the drive slider are detachably connected to the first sliding plate and the second sliding plate, respectively.

[0016] A simple and stable first drive module is provided, which drives a belt to rotate via a first motor, thereby driving the first and second sliding plates to slide synchronously along a second direction via drive sliders connected to both the first and second sliding plates. Only one motor is needed to synchronously drive the first and second sliding plates, reducing drive costs and ensuring the synchronicity of their sliding.

[0017] Specifically, since the first motor, fixed plate, support shaft, and drive slider are all designed to be detachable, the first motor, fixed plate, support shaft, and drive slider can be removed before adjusting the distance between the first and second mounting plates. Of course, the drive pulley and driven pulley can also be removed. After adjusting the distance between the first and second mounting plates, the fixed plate, support shaft, and drive slider of the corresponding size are reinstalled according to the distance between the first and second mounting plates. Then, the first motor, drive pulley, and driven pulley are reinstalled, and the belt is fitted. This ensures that the drive pulley, driven pulley, and belt remain in the exact center of the first and second sliding plates, ultimately ensuring that the belt and drive slider provide balanced drive to the first and second sliding plates.

[0018] In some embodiments, the second drive module includes a second motor, a rotating shaft, a first drive pulley, and a second drive pulley, wherein: the rotating shaft is detachably mounted on a first mounting plate and a second mounting plate via two bearing seats along a first direction; the first drive pulley and the second drive pulley are spaced apart on the rotating shaft; the second motor is mounted on the first mounting plate or the second mounting plate and is drively connected to the rotating shaft; the first conveyor belt is further configured to engage with the first drive pulley, and the second conveyor belt is further configured to engage with the second drive pulley; the second motor is used to drive the rotating shaft to rotate, so as to drive the first conveyor belt and the second conveyor belt to transport synchronously via the first drive pulley and the second drive pulley.

[0019] A simple and stable second drive module is provided, which drives a rotating shaft to rotate via a second motor, thereby driving the first and second conveyor belts to transport materials synchronously via the first and second drive pulleys. Only one motor is needed to synchronously drive the first and second conveyor belts, reducing drive costs and ensuring consistent conveying speeds for both belts.

[0020] Specifically, the rotating shaft is designed to be detachable. Therefore, before adjusting the distance between the first and second mounting plates, the rotating shaft, along with the first and second drive pulleys attached to it, can be removed.

[0021] After adjusting the distance between the first and second mounting plates, the rotating shafts with the first and second drive pulleys of corresponding length are reinstalled according to the distance between them. The first and second conveyor belts are then re-mounted to ensure that the length of the rotating shaft matches the distance between the first and second mounting plates. For example, when the distance between the first and second mounting plates is a larger first distance, a longer rotating shaft is used; conversely, when the distance between the first and second mounting plates is a smaller second distance, a shorter rotating shaft is used.

[0022] In some embodiments, at least two corresponding sets of first pulley groups and first conveyor belts are provided, and at least two first drive pulleys are also provided, with each first conveyor belt mounted on a corresponding first pulley group and first drive pulley; at least two corresponding sets of second pulley groups and second conveyor belts are provided, and at least two second drive pulleys are also provided, with each second conveyor belt mounted on a corresponding second pulley group and second drive pulley; when the distance between the first mounting plate and the second mounting plate is adjusted to a first distance, each first conveyor belt is used to cooperate in carrying at least one half-cell battery arranged in a second direction, and each second conveyor belt is used to cooperate in carrying at least one half-cell battery arranged in a second direction; when the distance between the first mounting plate and the second mounting plate is adjusted to a second distance, all the first and second conveyor belts are used to cooperate in carrying at least one whole cell battery arranged in a second direction.

[0023] Since there are at least two first conveyor belts and at least two second conveyor belts, when the distance between the first and second mounting plates is adjusted to a first distance, at least two first conveyor belts can cooperate to carry and transport half a solar cell, thereby ensuring the stability of the transport of the half solar cell. Similarly, at least two second conveyor belts can cooperate to carry and transport the half solar cell, thereby ensuring the stability of the transport of the half solar cell. When the distance between the first and second mounting plates is adjusted to a second distance, at least two first conveyor belts and at least two second conveyor belts cooperate to carry and transport the entire solar cell, thereby ensuring the stability of the transport of the entire solar cell.

[0024] In some embodiments, the cell-collecting and conveying mechanism further includes a first aligning wheel, a second aligning wheel, a third aligning wheel, and a fourth aligning wheel, wherein: the first aligning wheel is mounted on the outer side wall of the first mounting plate, the second aligning wheel is detachably mounted on the inner side wall of the first mounting plate, the third aligning wheel is detachably mounted on the inner side wall of the second mounting plate, and the fourth aligning wheel is mounted on the outer side wall of the second mounting plate. The first and second aligning wheels are located on opposite sides of the first conveyor belt, and the third and fourth aligning wheels are located on opposite sides of the second conveyor belt. The first and second aligning wheels are used to align and align half-cells of solar cells located on the first conveyor belt. The third and fourth aligning wheels are used to align and align half-cells of solar cells located on the second conveyor belt. The first and fourth aligning wheels are also used to align and align whole-cell solar cells located on the first and second conveyor belts.

[0025] Since both the second and third aligning rollers are detachable, when conveying a whole solar cell, they can be removed to ensure that the first and second conveyor belts can transport the whole solar cell, and the first and fourth aligning rollers can align the whole solar cell so that its sides are parallel to the conveying direction. When conveying half solar cells, the second and third aligning rollers are reinstalled. During transport, the first, second, third, and fourth aligning rollers can simultaneously align the two half solar cells being conveyed side-by-side on the first and second conveyor belts, ensuring that the sides of both half solar cells are parallel to the conveying direction.

[0026] This application also provides a film feeding device, which includes a basket-loading mechanism, a lifting mechanism, a film-collecting and conveying mechanism as described in any one of the above, a basket-removing mechanism, and a transport mechanism, wherein:

[0027] The basket-loading mechanism is used to transport a full basket containing whole battery cells or a half basket containing half battery cells to the lifting mechanism. The full basket has a first storage bin in which whole battery cells are stacked vertically. The half basket has a second storage bin and a third storage bin arranged side by side along a first direction, in which half battery cells are stacked vertically.

[0028] When the entire flower basket is on the wafer picking conveyor, the distance between the first mounting plate and the second mounting plate of the wafer picking conveyor is adjusted to the second distance. The first conveyor belt and the second conveyor belt of the wafer picking conveyor are configured to extend into the bottom of the first storage bin of the entire flower basket on the lifting mechanism under the drive of the first sliding plate and the second sliding plate, so as to cooperate with the lifting mechanism to take out the entire battery cells in the first storage bin one by one.

[0029] When the half-filled basket is on the wafer picking conveyor, the distance between the first mounting plate and the second mounting plate of the wafer picking conveyor is adjusted to the first distance. The first conveyor belt and the second conveyor belt of the wafer picking conveyor are configured to enter the bottom of the second storage bin and the third storage bin of the half-filled basket located on the lifting mechanism under the drive of the first sliding plate and the second sliding plate, respectively, so as to cooperate with the lifting mechanism to synchronously pick out the half-filled battery cells in the second storage bin and the third storage bin one by one.

[0030] After each piece is picked up by the picking and conveying mechanism, the lifting mechanism is configured to drive the whole flower basket or half flower basket to descend to a predetermined height.

[0031] The conveying mechanism is configured to pick up a whole cell or two half cells from the cell picking conveyor, and to transport the picked-up whole cell or two half cells to the next work station.

[0032] The layup mechanism is located below the layup mechanism and is configured to receive the empty full or half flower basket output by the lifting mechanism.

[0033] The feeding device provided in this application includes a feeding and conveying mechanism that enables compatible feeding of both whole and half-cell baskets. This allows the feeding device to supply both whole and half-cell batteries, achieving feeding compatibility. Furthermore, the loading mechanism automatically feeds whole-cell baskets or half-cell baskets onto a lifting mechanism. The lifting mechanism then lowers the whole-cell baskets or half-cell baskets one by one onto the feeding and conveying mechanism, ensuring that the feeding and conveying mechanism removes the whole or half-cell batteries one by one. The transport mechanism automatically transports the removed whole or half-cell batteries to a subsequent processing station for automatic supply of whole or half-cell batteries. The unloading mechanism automatically removes the empty whole or half-cell baskets from the lifting mechanism.

[0034] In some embodiments, the lifting mechanism includes a lifting drive and a transfer unit, wherein: the transfer unit is connected to a movable part of the lifting drive, the lifting drive is configured to drive the transfer unit to switch between a high position and a low position, and the transfer unit is configured to receive a half-flower basket or a whole flower basket and drive the half-flower basket or the whole flower basket to move along a second direction; when the transfer unit rises to a high position, it docks with the basket-raising mechanism to receive the whole flower basket or half-flower basket conveyed by the basket-raising mechanism; when the transfer unit descends to a low position, it docks with the basket-lowering mechanism to convey the empty whole flower basket or half-flower basket to the basket-lowering mechanism.

[0035] The lifting drive unit drives the transfer unit to rise and fall, enabling the transfer unit to alternately dock with the basket-up mechanism and the basket-down mechanism. This allows the transfer unit to automatically accept whole baskets containing whole battery cells or half baskets containing half battery cells from the basket-up mechanism, and to transport empty whole baskets or half baskets to the basket-down mechanism.

[0036] In some embodiments, the transfer unit includes a support frame, an upper pressing assembly, a lower pressing assembly, and a carrying assembly, wherein: the support frame is connected to the movable part of the lifting drive unit, and an accommodating space for accommodating a whole flower basket or a half flower basket is formed between the top and bottom of the support frame; the upper pressing assembly is disposed at the top of the support frame, and the lower pressing assembly and the carrying assembly are both disposed at the bottom of the support frame; the carrying assembly is used to carry and transport the whole flower basket or half flower basket along the second direction; the upper pressing assembly is used to press down on the top of the whole flower basket or half flower basket; and the lower pressing assembly is used to press against the bottom of the whole flower basket or half flower basket.

[0037] When the transfer unit connects with the basket-mounting mechanism, the carrying component receives the full basket containing a complete battery cell or the half basket containing a half battery cell from the basket-mounting mechanism and inputs the full or half basket into the receiving space. Subsequently, the upper and lower pressing components work together to press the full or half basket from above and below, preventing it from tilting or falling during the material removal process. When the full or half basket is emptied, and the transfer unit connects with the lower basket mechanism, the upper and lower pressing components release the emptied full or half basket, and the carrying component transports the full or half basket toward the lower basket mechanism, thus allowing the emptied full or half basket to automatically enter the lower basket mechanism.

[0038] In some embodiments, two lifting mechanisms and two cell picking and conveying mechanisms are provided, wherein: each lifting mechanism is configured to translate along a first direction to dock with the basket mechanism, the corresponding cell picking and conveying mechanism or the basket lowering mechanism; the conveying mechanism is configured to alternately pick up whole cells or half cells from the two cell picking and conveying mechanisms, and to convey the picked whole cells or half cells to the next work station.

[0039] Two cell picking and conveying mechanisms simultaneously pick up cells from the full or half cell baskets on the corresponding lifting mechanisms, enabling the conveying mechanism to alternately pick up full or half cell cells from the two cell picking and conveying mechanisms, and to transport the picked-up full or half cell cells to the next work station, thereby improving the cell feeding efficiency of the cell feeding device.

[0040] In some embodiments, the conveying mechanism includes a translation drive unit, a rotation drive unit, a spacing drive unit, a first suction cup assembly, and a second suction cup assembly, wherein: the rotation drive unit is connected to a movable part of the translation drive unit, the spacing drive unit is connected to a movable part of the rotation drive unit, and the first suction cup assembly and the second suction cup assembly are connected side-by-side to the movable part of the spacing drive unit; the spacing drive unit is configured to drive the first suction cup assembly and the second suction cup assembly to move closer together or separate to both sides, so as to adjust the spacing between the first suction cup assembly and the second suction cup assembly to a third spacing or a fourth spacing, wherein, when the third spacing is less than the fourth spacing, the first suction cup assembly and the second suction cup assembly are used to cooperate to pick up a whole battery cell; when the spacing between the first suction cup assembly and the second suction cup assembly is the fourth spacing, the first suction cup assembly and the second suction cup assembly are used to pick up a half battery cell respectively; the translation drive unit is used to drive the first suction cup assembly and the second suction cup assembly to translate synchronously, and the rotation drive unit is used to drive the first suction cup assembly and the second suction cup assembly to rotate synchronously in the horizontal plane.

[0041] When a whole solar cell needs to be picked up and transported from the pick-up and transport mechanism, the distance between the first and second suction cup assemblies is adjusted to a smaller third distance, and the first and second suction cup assemblies work together to pick up and transport one whole solar cell. When two half solar cells need to be picked up and transported from the pick-up and transport mechanism, the distance between the first and second suction cup assemblies is adjusted to a larger fourth distance, and the first and second suction cup assemblies pick up and transport one half solar cell respectively. It is evident that the transport mechanism provided in this application achieves compatibility in transporting both whole and half solar cells. Furthermore, the rotary drive unit can drive the first and second suction cup assemblies to rotate synchronously in the horizontal plane, thereby achieving orientation adjustment of the whole or half solar cell during transport to meet the requirements of subsequent processing.

[0078] To make the above-mentioned objects, 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. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0079] As described in the background section, due to the obstruction of a set of support rods in the middle of the half-basket, and since the conveying mechanism needs to extend into the basket to retrieve the battery cells, the support rods in the middle of the half-basket prevent the conveying mechanism adapted to the full-basket from extending into the half-basket. This results in the retrieval conveying mechanism adapted to the full-basket being unable to match the half-basket. In other words, the existing retrieval conveying mechanism is not compatible with retrieval operations for both full-basket and half-basket operations.

[0080] In view of this, this application provides a flower picking and conveying mechanism that is compatible with picking up both whole flower baskets and half flower baskets.

[0081] like Figure 1 As shown, the wafer picking and conveying mechanism 100 in this embodiment includes a base 1, a first mounting plate 2, a second mounting plate 3, a first sliding plate 4, a second sliding plate 5, a first drive module 6, a first pulley group 7, a first conveyor belt 8, a second pulley group 9, a second conveyor belt 10, and a second drive module 110, wherein:

[0082] The first mounting plate 2 and the second mounting plate 3 are disposed on the base 1 at intervals along a first direction (such as the X direction), and are both adjustablely connected to the base 1 along the first direction.

[0083] The first sliding plate 4 is slidably connected to the first mounting plate 2, the second sliding plate 5 is slidably connected to the second mounting plate 3, and the first driving module 6 is disposed on the first mounting plate 2 and the second mounting plate 3. The first driving module 6 is used to drive the first sliding plate 4 and the second sliding plate 5 to slide synchronously along a second direction (such as the Y-axis direction), the second direction being perpendicular to the first direction.

[0084] The first pulley assembly 7 is at least partially mounted on the first sliding plate 4, and the first conveyor belt 8 is fitted along the second direction onto the moving parts of the first pulley assembly 7 and the second drive module 110. The second pulley assembly 9 is at least partially mounted on the second sliding plate 5, and the second conveyor belt 10 is fitted along the second direction onto the moving parts of the second pulley assembly 9 and the second drive module 110. That is, the first pulley assembly 7 includes a plurality of first pulleys, at least some of which are mounted on the first sliding plate 4 and can slide synchronously with the first sliding plate 4 in the second direction, thereby driving the first conveyor belt 8 to extend and retract in the second direction. Similarly, the second pulley assembly 9 includes a plurality of second pulleys, at least some of which are mounted on the second sliding plate 5 and can slide synchronously with the second sliding plate 5 in the second direction, thereby driving the second conveyor belt 10 to extend and retract in the second direction.

[0085] The second drive module 110 is used to drive the first conveyor belt 8 and the second conveyor belt 10 to synchronously transport battery cells along the second direction.

[0086] By adjusting the positions of the first mounting plate 2 and the second mounting plate 3 on the base 1, so that the distance between the first mounting plate 2 and the second mounting plate 3 is adjusted to a first distance, the first conveyor belt 8 and the second conveyor belt 10 are respectively used to carry and transport one half-cell battery cell. By adjusting the positions of the first mounting plate 2 and the second mounting plate 3 on the base 1, so that the distance between the first mounting plate 2 and the second mounting plate 3 is adjusted to a second distance, the first conveyor belt 8 and the second conveyor belt 10 are used to cooperate in carrying and transporting one whole cell battery cell, wherein the second distance is smaller than the first distance.

[0087] The process of picking up and conveying half-flower baskets 600 by the film picking and conveying mechanism 100 in this embodiment is as follows:

[0088] First, adjust the distance between the first mounting plate 2 and the second mounting plate 3 to a larger first distance.

[0089] Subsequently, the first drive module 6 drives the first sliding plate 4 and the second sliding plate 5 to move synchronously along the second direction toward the half-flower basket 600, so that the first conveyor belt 8 and the second conveyor belt 10 respectively extend into the two storage bins of the half-flower basket (the second storage bin 601 and the third storage bin 602, respectively).

[0090] The second drive module 110 drives the first conveyor belt 8 and the second conveyor belt 10 to synchronously transport away from the half-cell basket 600 along the second direction, so that the first conveyor belt 8 and the second conveyor belt 10 synchronously take out the half-cells of the corresponding storage bins one by one.

[0091] The process of picking and conveying whole flower baskets by the picking and conveying mechanism 100 in this embodiment is as follows:

[0092] First, adjust the spacing between the first mounting plate 2 and the second mounting plate 3 to a smaller second spacing.

[0093] Subsequently, the first drive module 6 drives the first sliding plate 4 and the second sliding plate 5 to move synchronously along the second direction toward the whole flower basket, so that the first conveyor belt 8 and the second conveyor belt 10 simultaneously extend into the storage bin (referred to as the first storage bin) of the whole flower basket.

[0094] The second drive module 110 drives the first conveyor belt 8 and the second conveyor belt 10 to move away from the half-battery basket 600 in the second direction simultaneously, so that the first conveyor belt 8 and the second conveyor belt 10 cooperate with each other to take out the whole battery cell from the storage bin one by one.

[0095] As can be seen, the flower picking and conveying mechanism provided in this application embodiment achieves compatibility with picking up both whole flower baskets and half flower baskets.

[0096] Optionally, the second mounting plate 3, the first mounting plate 2, and the base 1 are connected in the same way. Taking the connection between the first mounting plate 2 and the base 1 as an example, the base 1 is provided with a waist-shaped hole extending along the first direction, the first mounting plate 2 is provided with a screw hole communicating with the waist-shaped hole, and the first mounting plate 2 is screwed onto the base 1 by bolts passing through the waist-shaped hole and the screw hole.

[0097] Specifically, when it is necessary to adjust the installation position of the first mounting plate 2 in the first direction, first loosen the bolts, then push the first mounting plate 2 to slide along the waist-shaped hole, and after sliding into place, tighten the bolts again to fix the first mounting plate 2 to the base 1.

[0098] Of course, the connection between the second mounting plate 3, the first mounting plate 2, and the base 1 can also adopt other implementation methods, as long as the installation position of the second mounting plate 3 and the first mounting plate 2 in the first direction can be adjusted. Taking the first mounting plate 2 as an example, for instance, the first mounting plate 2 is slidably connected to the base 1 via a short slide rail extending along the first horizontal direction. Bolts are also passed through the first mounting plate 2. The base 1 has a number of screw holes that match the bolts at intervals along the first horizontal direction. When the first mounting plate 2 slides into place along the short slide rail, it can be screwed and fixed into the corresponding screw holes.

[0099] like Figure 3 As shown, optionally, the first mounting plate 2 and the second mounting plate 3 are respectively provided with slide rails 160 extending along the second direction, and the first sliding plate 4 and the second sliding plate 5 are respectively slidably mounted on the corresponding slide rails 160. With this configuration, the sliding guidance of the first sliding plate 4 and the second sliding plate 5 can be implemented to prevent the first sliding plate 4 and the second sliding plate 5 from getting stuck during the sliding process.

[0100] like Figure 2 and Figure 4 As shown, optionally, the first drive module 6 includes a first motor 61, a fixed plate 62, a support shaft 63, a drive pulley 64, a driven pulley 65, a belt 66, and a drive slider 67. The first motor 61 is detachably mounted on the fixed plate 62, which is detachably mounted on either the first mounting plate 2 or the second mounting plate 3. The drive pulley 64 is connected to the drive end of the first motor 61. The driven pulley 65 is rotatably mounted on the support shaft 63, which is detachably mounted on either the first mounting plate 2 or the second mounting plate 3 along a first direction. The belt 66 is fitted onto the drive pulley 64 and the driven pulley 65 along a second direction, and is located between the first mounting plate 2 and the second mounting plate 3. The drive slider 67 is connected to one side of the belt 66 (e.g., the upper side), and both ends of the drive slider 67 are detachably connected to the first sliding plate 4 and the second sliding plate 5, respectively.

[0101] When the first motor 61 drives the belt 66 to rotate, the belt 66 can drive the first sliding plate 4 and the second sliding plate 5 to slide synchronously in the second direction via the drive slider 67, which is connected to both the first sliding plate 4 and the second sliding plate 5. In other words, only one drive motor is needed to achieve synchronous driving of the first sliding plate 4 and the second sliding plate 5, reducing the driving cost and ensuring the sliding synchronization of the first sliding plate 4 and the second sliding plate 5.

[0102] Specifically, since the first motor 61, fixed plate 62, support shaft 63, and drive slider 67 are all designed to be detachable, the first motor 61, fixed plate 62, support shaft 63, and drive slider 67 can be removed before adjusting the distance between the first mounting plate 2 and the second mounting plate 3. Of course, the drive pulley 64 and driven pulley 65 are also removed. After adjusting the distance between the first mounting plate 2 and the second mounting plate 3, the fixed plate 62, support shaft 63, and drive slider 67 of the corresponding dimensions are reinstalled according to the distance between the first mounting plate 2 and the second mounting plate 3. Then, the first motor 61, drive pulley 64, and driven pulley 65 are reinstalled, and the belt 66 is fitted. This ensures that the drive pulley 64, driven pulley 65, and belt 66 remain in the exact center of the first sliding plate 4 and the second sliding plate 5, ultimately ensuring that the belt 66 and drive slider 67 provide balanced drive to the first sliding plate 4 and the second sliding plate 5.

[0103] For example, such as Figure 6 As shown, when the distance between the first mounting plate 2 and the second mounting plate 3 is adjusted to a larger first distance, by replacing the support shaft 63 and the drive slider 67 with the larger length dimension along the first direction, it can be finally ensured that the driving pulley 64, the driven pulley 65 and the belt 66 are still in the middle position of the first sliding plate 4 and the second sliding plate 5.

[0104] For example, such as Figure 7 As shown, when the distance between the first mounting plate 2 and the second mounting plate 3 is adjusted to a smaller second distance, by replacing the support shaft 63 and the drive slider 67 with smaller length dimensions along the first direction, it can be finally ensured that the driving pulley 64, the driven pulley 65 and the belt 66 are still in the middle position of the first sliding plate 4 and the second sliding plate 5.

[0105] like Figure 3 and Figure 5 As shown, optionally, the second drive module 110 includes a second motor 111, a rotating shaft 112, a first drive pulley 113 and a second drive pulley 114, wherein: the rotating shaft 112 is detachably mounted on the first mounting plate 2 and the second mounting plate 3 along the first direction via two bearing seats 115, and the first drive pulley 113 and the second drive pulley 114 are spaced apart on the rotating shaft 112.

[0106] The second motor 111 is mounted on either the first mounting plate 2 or the second mounting plate 3, and is connected to the rotating shaft 112 for transmission. The first conveyor belt 8 is also configured to engage with the first drive pulley 113, and the second conveyor belt 10 is also configured to engage with the second drive pulley 114. The second motor 111 drives the rotating shaft 112 to rotate, thereby driving the first conveyor belt 8 and the second conveyor belt 10 to transport synchronously via the first drive pulley 113 and the second drive pulley 114.

[0107] When the second motor 111 drives the rotating shaft 112 to rotate, the rotating shaft 112 drives the first conveyor belt 8 and the second conveyor belt 10 to transport synchronously via the first drive pulley 113 and the second drive pulley 114. In other words, only one motor is needed to synchronously drive the first conveyor belt 8 and the second conveyor belt 10, reducing the driving cost and ensuring the consistency of the conveying speed of the first conveyor belt 8 and the second conveyor belt 10.

[0108] Specifically, the rotating shaft 112 is designed to be detachable. Therefore, before adjusting the distance between the first mounting plate 2 and the second mounting plate 3, the rotating shaft 112, along with the first drive pulley 113 and the second drive pulley 114 attached to it, can be removed. After adjusting the distance between the first mounting plate 2 and the second mounting plate 3, the rotating shaft 112 with the corresponding length of the first drive pulley 113 and the second drive pulley 114 is reinstalled according to the distance between the first mounting plate 2 and the second mounting plate 3, and the first conveyor belt 8 and the second conveyor belt 10 are re-attached, thus ensuring that the length of the rotating shaft 112 matches the distance between the first mounting plate 2 and the second mounting plate 3.

[0109] For example, such as Figure 6As shown, when the distance between the first mounting plate 2 and the second mounting plate 3 is a large first distance, a longer rotating shaft 112 is used, and the distance between the first drive pulley 113 and the second drive pulley 114 on it is large.

[0110] For example, such as Figure 7 As shown, when the distance between the first mounting plate 2 and the second mounting plate 3 is a smaller second distance, a shorter rotating shaft 112 is used, and the distance between the first drive pulley 113 and the second drive pulley 114 on it is smaller.

[0111] Optionally, the first pulley set 7 and the first conveyor belt 8 are configured as at least two corresponding sets (e.g., Figures 1 to 3 In the two sets shown in the embodiment, the first drive pulley 113 is also configured with at least two, and each first conveyor belt 8 is fitted onto the corresponding first pulley set 7 and first drive pulley 113. Similarly, the second pulley set 9 and the second conveyor belt 10 are configured with at least two corresponding sets (e.g., Figures 1 to 3 In the two sets shown in the embodiment, the second drive pulley 114 is also set to at least two, and each second conveyor belt 10 is fitted onto the corresponding second pulley set 9 and the second drive pulley 114.

[0112] When the distance between the first mounting plate 2 and the second mounting plate 3 is adjusted to the first distance, each of the first conveyor belts 8 is used to carry at least one half of the battery cell arranged in the second direction, and each of the second conveyor belts 10 is used to carry at least one half of the battery cell arranged in the second direction.

[0113] When the distance between the first mounting plate 2 and the second mounting plate 3 is adjusted to the second distance, all the first conveyor belts 8 and the second conveyor belts 10 are used to carry at least one whole cell arranged in the second direction.

[0114] Since there are at least two first conveyor belts 8 and at least two second conveyor belts 10, when the distance between the first mounting plate 2 and the second mounting plate 3 is adjusted to a first distance, at least two first conveyor belts 8 can cooperate to carry and transport half of the solar cell, thereby ensuring the stability of the transport of the half solar cell. Similarly, at least two second conveyor belts 10 can cooperate to carry and transport half of the solar cell, thereby ensuring the stability of the transport of the half solar cell. When the distance between the first mounting plate 2 and the second mounting plate 3 is adjusted to a second distance, at least two first conveyor belts 8 and at least two second conveyor belts 10 cooperate to carry and transport the entire solar cell, thereby ensuring the stability of the transport of the entire solar cell.

[0115] like Figure 1As shown, the wafer conveying mechanism 100 in this embodiment further includes a first aligning wheel 120, a second aligning wheel 130, a third aligning wheel 140, and a fourth aligning wheel 150. The first aligning wheel 120 is mounted on the outer wall of the first mounting plate 2; the second aligning wheel 130 is detachably mounted on the inner wall of the first mounting plate 2; the third aligning wheel 140 is detachably mounted on the inner wall of the second mounting plate 3; and the fourth aligning wheel 150 is mounted on the outer wall of the second mounting plate 3. The first aligning wheel 120 and the second aligning wheel 130 are located on opposite sides of the first conveyor belt 8, while the third aligning wheel 140 and the fourth aligning wheel 150 are located on opposite sides of the second conveyor belt 10.

[0116] The first alignment roller 120 and the second alignment roller 130 are used to align and align half-cells located on the first conveyor belt 8. The third alignment roller 140 and the fourth alignment roller 150 are used to align and align half-cells located on the second conveyor belt 10. The first alignment roller 120 and the fourth alignment roller 150 are also used to align and align whole-cells located on the first conveyor belt 8 and the second conveyor belt 10.

[0117] Since both the second aligning wheel 130 and the third aligning wheel 140 are detachable, when it is necessary to transport a whole solar cell, removing the second aligning wheel 130 and the third aligning wheel 140 ensures that the first conveyor belt 8 and the second conveyor belt 10 can transport the whole solar cell, and the first aligning wheel 120 and the fourth aligning wheel 150 can align the whole solar cell so that the side of the whole solar cell is parallel to the transport direction. When it is necessary to transport half solar cells, the second aligning wheel 130 and the third aligning wheel 140 are reinstalled. The first aligning wheel 120, the second aligning wheel 130, the third aligning wheel 140, and the fourth aligning wheel 150 can synchronously align the two half solar cells being transported side by side on the first conveyor belt 8 and the second conveyor belt 10 during the transport process, so that the side of both half solar cells is parallel to the transport direction.

[0118] Based on the same concept, this application also provides a film feeding device. For example... Figure 8 As shown, the film supply device in this embodiment includes a basket loading mechanism 200, a lifting mechanism 300, a film picking and conveying mechanism 100 as described in any of the above embodiments, a basket unloading mechanism 400, and a transport mechanism 500, wherein:

[0119] The basket-loading mechanism 200 is used to transport a full basket containing whole battery cells or a half basket containing half battery cells to the lifting mechanism 300. The full basket has a first storage bin, in which whole battery cells are stacked vertically. Figure 1As shown, the half-battery basket 600 has a second storage bin 601 and a third storage bin 602 arranged side by side along the first direction, and half-battery cells are stacked vertically in the second storage bin 601 and the third storage bin 602 respectively.

[0120] When the wafer picking conveyor 100 is carrying a whole wafer, the distance between the first mounting plate 2 and the second mounting plate 3 of the wafer picking conveyor 100 is adjusted to a smaller second distance. The first conveyor belt 8 and the second conveyor belt 10 of the wafer picking conveyor 100 are configured to extend simultaneously into the bottom of the first storage bin of the whole wafer on the lifting mechanism 300 under the drive of the first sliding plate 4 and the second sliding plate 5, so as to cooperate with the lifting mechanism 300 to take out the whole wafers one by one from the first storage bin.

[0121] When the half-cell basket 600 is on the cell picking conveyor 100, the distance between the first mounting plate 2 and the second mounting plate 3 of the cell picking conveyor 100 is adjusted to a larger first distance. The first conveyor belt 8 and the second conveyor belt 10 of the cell picking conveyor 100 are configured to enter the bottom of the second storage bin 601 and the third storage bin 602 of the half-cell basket 600 located on the lifting mechanism 300 under the drive of the first sliding plate 4 and the second sliding plate 5, respectively, so as to cooperate with the lifting mechanism 300 to synchronously pick out the half-cells of the battery cells in the second storage bin 601 and the third storage bin 602 one by one.

[0122] After each cell retrieval by the cell retrieval and conveying mechanism 100, the lifting mechanism 300 is configured to drive the whole or half cell basket to descend a predetermined height, so that the whole or half cell currently located at the bottom of the whole or half cell basket falls onto the cell retrieval and conveying mechanism 100.

[0123] The conveying mechanism is configured to pick up a whole cell or two half cells from the cell picking conveyor 100, and to transport the picked-up whole cell or two half cells to the next work station.

[0124] The layup mechanism 400 is located below the layup mechanism 200 and is configured to receive the empty full or half flower basket output by the lifting mechanism 300.

[0125] The feeding device provided in this application, by adjusting the distance between the first mounting plate 2 and the second mounting plate 3 through its feeding and conveying mechanism 100, can achieve compatibility in feeding both whole and half battery cells. Thus, the feeding device can supply both whole and half battery cells, thereby achieving compatibility in feeding both whole and half battery cells.

[0126] In addition, the basket loading mechanism 200 can automatically load whole flower baskets containing whole battery cells or half flower baskets containing half battery cells onto the lifting mechanism 300.

[0127] The lifting mechanism 300 can lift and lower the entire battery cell in the whole basket or the half battery cell in the half basket so that they can fall one by one onto the cell picking and conveying mechanism 100, ensuring that the cell picking and conveying mechanism 100 can pick out the whole battery cell or the half battery cell one by one.

[0128] The conveying mechanism 500 can automatically transport the removed whole or half battery cells to the next processing station to achieve automatic feeding of whole or half battery cells.

[0129] The basket-dropping mechanism 400 can automatically remove the emptied whole or half flower basket from the lifting mechanism 300.

[0130] like Figures 8 to 9 As shown, optionally, the lifting mechanism 300 includes a lifting drive unit 301 and a transfer unit 302, wherein: the transfer unit 302 is connected to the movable part of the lifting drive unit 301, the lifting drive unit 301 is configured to drive the transfer unit 302 to switch between a high position and a low position, and the transfer unit 302 is configured to receive a half-flower basket or a whole flower basket and drive the half-flower basket or the whole flower basket to move along a second direction. When the transfer unit 302 rises to the high position, it docks with the basket-raising mechanism 200 to receive the whole flower basket or half-flower basket conveyed by the basket-raising mechanism 200. When the transfer unit 302 descends to the low position, it docks with the basket-lowering mechanism 400 to convey the emptied whole flower basket or half-flower basket to the basket-lowering mechanism 400.

[0131] The lifting drive unit 301 drives the transfer unit 302 to rise and fall, so that the transfer unit 302 can alternately dock with the basket mechanism 200 and the basket mechanism 400. This allows the transfer unit 302 to automatically accept whole baskets containing whole battery cells or half baskets containing half battery cells from the basket mechanism 200, and to transport empty whole baskets or half baskets to the basket mechanism 400.

[0132] The lifting drive unit 301 can adopt various existing linear drive modules that can drive the transfer unit 302 to lift, such as a screw drive module consisting of a motor, a lead screw, a lead screw nut, etc.

[0133] like Figure 9As shown, optionally, the transfer unit 302 includes a support frame 303, an upper pressing component 304, a lower pressing component 305, and a carrying component 306. The support frame 303 is connected to the movable part of the lifting drive unit 301, and a receiving space for accommodating a whole or half flower basket is formed between the top and bottom of the support frame 303. The upper pressing component 304 is disposed at the top of the support frame 303, while the lower pressing component 305 and the carrying component 306 are both disposed at the bottom of the support frame 303. The carrying component 306 is used to carry and transport the whole or half flower basket along the second direction. The upper pressing component 304 is used to press the top of the whole or half flower basket downwards, and the lower pressing component 305 is used to press the bottom of the whole or half flower basket against it.

[0134] When the transfer unit 302 docks with the basket loading mechanism 200, the carrying component 306 receives the whole basket containing a whole battery cell or the half basket containing a half battery cell from the basket loading mechanism 200 and inputs the whole basket or half basket into the receiving space. Subsequently, the upper pressing component 304 and the lower pressing component 305 work together to press the whole basket or half basket from above and below to prevent the whole basket or half basket from tilting or falling during the material retrieval process. When the whole basket or half basket is emptied, when the transfer unit 302 docks with the basket unloading mechanism 400, the upper pressing component 304 and the lower pressing component 305 first release the emptied whole basket or half basket, and the carrying component 306 then transports the whole basket or half basket toward the basket unloading mechanism 400, so that the emptied whole basket or half basket automatically enters the basket unloading mechanism 400.

[0135] Optionally, the pressing assembly 304 includes a first cylinder and a first pressure plate. The first cylinder is connected to the top of the support frame 303, and the first pressure plate is connected to the telescopic rod of the first cylinder. When the telescopic rod of the first cylinder extends, the first pressure plate presses down on the top plate of the entire or half of the flower basket. When the telescopic rod of the first cylinder retracts, the first pressure plate disengages from the top plate of the entire or half of the flower basket.

[0136] Optionally, the pressing assembly 305 includes a second cylinder and a second pressure plate. The second cylinder is connected to the bottom of the support frame 303, and the second pressure plate is connected to the telescopic rod of the second cylinder. When the telescopic rod of the second cylinder extends, the second pressure plate presses inward against the bottom plate of the entire or half of the flower basket. When the telescopic rod of the second cylinder retracts, the second pressure plate disengages from the bottom plate of the entire or half of the flower basket.

[0137] Optionally, the carrying component 306 includes a conveyor belt arranged side by side at the bottom of the support frame 303. The conveyor belt is configured to convey in both directions to receive a full basket containing a whole battery cell or a half basket containing a half battery cell from the basket mechanism 200, or to convey an empty full basket or half basket to the basket mechanism 400.

[0138] Optionally, the layup mechanism 200 and the layup retrieval mechanism 400 have the same structure. Taking the layup retrieval mechanism 400 as an example, as follows... Figure 9 The device includes a translation module 401 and a carrying and conveying unit 402. The carrying and conveying unit 402 is connected to the movable part of the translation module 401. The translation drive unit 40 is used to drive the carrying and conveying unit 402 to translate, so that the carrying and conveying unit 402 docks with the carrying component 306 that has been lowered to a lower position, so as to receive the empty whole flower basket or half flower basket output by the carrying component 306.

[0139] The translation module 401 can employ various existing linear drive modules capable of driving the translation of the carrier component 306, such as a synchronous belt drive module consisting of a motor, a synchronous belt, and a slide rail pair. Optionally, the carrier conveying unit 402 includes a mounting frame and a conveyor belt 403, wherein the mounting frame is connected to the movable part of the translation module 401, and the conveyor belt 403 is mounted on the mounting frame. The conveyor belt 403 is configured to receive the emptied whole or half flower basket output from the carrier component 306, and transport the whole or half flower basket away from the carrier component 306 to a target location for buffering, waiting for the whole or half flower basket to be taken away.

[0140] like Figure 8 As shown, optionally, two lifting mechanisms 300 and two cell-picking conveying mechanisms 100 are configured, wherein each lifting mechanism 300 is configured to translate along a first direction to dock with the basket-up mechanism 200 and the corresponding cell-picking conveying mechanism 100 or basket-down mechanism 400. The conveying mechanism 500 is configured to alternately pick up whole cells or half cells from the two cell-picking conveying mechanisms 100, and to convey the picked-up whole cells or half cells to the next processing station.

[0141] With this configuration, the two cell picking and conveying mechanisms 100 can simultaneously pick up cells from the full or half cell baskets on the corresponding lifting mechanism 300, enabling the conveying mechanism to alternately pick up full or half cell cells from the two cell picking and conveying mechanisms 100, and to transport the picked-up full or half cell cells to the next processing station, thereby improving the cell feeding efficiency of the cell feeding device of this application.

[0142] like Figure 10As shown, optionally, the conveying mechanism 500 includes a translation drive unit 501, a rotation drive unit 502, a spacing drive unit 503, a first suction cup assembly 504, and a second suction cup assembly 505, wherein: the rotation drive unit 502 is connected to the movable part of the translation drive unit 501, the spacing drive unit 503 is connected to the movable part of the rotation drive unit 502, and the first suction cup assembly 504 and the second suction cup assembly 505 are connected side-by-side to the movable part of the spacing drive unit 503. The spacing drive unit 503 is configured to drive the first suction cup assembly 504 and the second suction cup assembly 505 to move closer together or separate to both sides, so as to adjust the spacing between the first suction cup assembly 504 and the second suction cup assembly 505 to a third spacing or a fourth spacing, wherein the third spacing is smaller than the fourth spacing.

[0143] When the distance between the first suction cup assembly 504 and the second suction cup assembly 505 is the third distance, the first suction cup assembly 504 and the second suction cup assembly 505 are used to cooperate to pick up a whole battery cell.

[0144] When the distance between the first suction cup assembly 504 and the second suction cup assembly 505 is the fourth distance, the first suction cup assembly 504 and the second suction cup assembly 505 are used to pick up one and a half battery cells respectively.

[0145] The translation drive unit 501 is used to drive the first suction cup assembly 504 and the second suction cup assembly 505 to translate synchronously, and the rotation drive unit 502 is used to drive the first suction cup assembly 504 and the second suction cup assembly 505 to rotate synchronously in the horizontal plane.

[0146] Specifically, when it is necessary to pick up and transport a whole cell from the cell picking and conveying mechanism 100, the distance between the first suction cup assembly 504 and the second suction cup assembly 505 is adjusted to a smaller third distance. In this way, the first suction cup assembly 504 and the second suction cup assembly 505 can cooperate to pick up and transport a whole cell.

[0147] When it is necessary to pick up and transport two half-cells of solar cells that are transported side by side from the cell picking and conveying mechanism 100, the distance between the first suction cup assembly 504 and the second suction cup assembly 505 is adjusted to a larger fourth distance. In this way, the first suction cup assembly 504 and the second suction cup assembly 505 can pick up one half-cell of solar cell from the first conveyor belt 8 and the second conveyor belt 9 of the cell picking and conveying mechanism 100 respectively, and transport the two picked-up half-cells simultaneously.

[0148] It can be seen that by configuring the handling mechanism 500, the handling mechanism 500 can be compatible with the handling of whole battery cells and half battery cells.

[0149] In addition, the rotary drive unit 502 can drive the first suction cup assembly 504 and the second suction cup assembly 505 to rotate synchronously in the horizontal plane, thereby realizing the orientation adjustment of the whole cell or half cell during the handling process to meet the processing requirements of the subsequent process.

[0150] Taking the handling of half a solar cell as an example, such as Figure 11 As shown, in one application example, the transport mechanism 500 needs to alternately transport half-cells 800 from the two cell picking and conveying mechanisms 100 to the welding conveyor line 700, and the welding conveyor line 700 will transport the half-cells 800 to the subsequent welding station for welding into strings.

[0151] However, the long side of the half-cell 800 taken from the half-cell basket on the cell pick-up and conveying mechanism 100 is parallel to the second direction (e.g., the Y direction), while the welding conveyor line 700 needs to convey the half-cell 800 with its long side parallel to the first direction (e.g., the X direction) to the welding station for welding into strings. Therefore, before the first suction cup assembly 504 and the second suction cup assembly 505 place the two picked-up half-cells 800 onto the welding conveyor line 700, the rotary drive unit 502 needs to drive the first suction cup assembly 504 and the second suction cup assembly 505 to rotate synchronously by 90°, thereby adjusting the orientation of the half-cells 800. In addition, after the rotary drive unit 502 completes the rotary drive, the spacing drive unit 503 can also adjust the spacing between the two half-cells 800 to the spacing required for stringing by adjusting the spacing between the first suction cup assembly 504 and the second suction cup assembly 505.

[0152] The translation drive unit 501 can be any existing linear drive module, such as a synchronous belt drive module consisting of a motor, a synchronous belt, and a slide rail pair. The rotary drive unit 502 can be any existing rotary drive module capable of driving the pitch drive unit 503 to rotate in the horizontal plane, such as a rotary motor. The pitch drive unit 503 can be, for example, a double-headed cylinder.
