Description

Technical Field

[0001] This application relates to the field of photovoltaic module production, specifically a labeling mechanism and photovoltaic module production equipment. Background Technology

[0002] In the production process of photovoltaic modules, a predetermined number of cell strings are first welded together using busbars to form cell string assemblies. These assemblies are then sealed between a glass backsheet and a cover plate. To facilitate user identification of the photovoltaic module's model and brand, labels containing photovoltaic module information are typically affixed to the side of the busbar closest to the glass backsheet, allowing users to quickly view the module information through the glass backsheet.

[0003] Currently, labels are typically affixed to the busbars using a labeling mechanism. However, existing labeling mechanisms are integrated with label printers, resulting in a large footprint. Therefore, a separate labeling station is needed for the labeling operation. The conveyor line first transports the stacked battery strings and glass backsheets to the labeling station. Then, a handling mechanism lifts the battery strings from the glass backsheet, and the labeling mechanism affixes the labels to the lower surface of the busbars. Finally, the handling mechanism places the battery strings back onto the glass backsheet. In other words, the battery strings need to be lifted and lowered from the glass backsheet once during the labeling process, which slows down the work cycle, reduces the production efficiency of photovoltaic modules, and increases the risk of damage to the battery strings. Utility Model Content

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

[0005] A labeling mechanism includes a moving component, a support frame, a swing arm assembly, and an adsorption block, wherein:

[0006] The support frame is connected to the movable part of the moving component, the first end of the swing arm assembly is rotatably connected to the support frame, and the adsorption block is connected to the second end of the swing arm assembly.

[0007] The adsorption block is used to pick up labels from the printing mechanism, the moving component is used to drive the adsorption block to translate along a first horizontal direction and to drive the adsorption block to rise and fall, and the swing arm component is used to drive the adsorption block to swing in the horizontal plane.

[0008] The labeling mechanism provided in this application is independently configured with a label printer, allowing it to be placed on the conveying path of the backsheet conveyor. When the transport mechanism moves the battery string assembly to be stacked above the backsheet, the labeling mechanism affixes a label to the busbar on the lower surface of the battery string assembly. Subsequently, the transport mechanism stacks the battery string assembly onto the backsheet. Therefore, using the labeling mechanism provided in this application, the labeling action can be completed during the stacking of the battery string assembly onto the backsheet by the transport mechanism. This eliminates the need for additional labeling stations and additional lifting / lowering operations on the battery string assembly, saving equipment space, accelerating the work cycle, improving the production efficiency of photovoltaic modules, and reducing the risk of damage to the battery string assembly.

[0009] In some embodiments, the swing arm assembly includes a first drive unit and a first swing arm, wherein a first end of the first swing arm is rotatably connected to a support frame and is drively connected to a first drive unit disposed on the support frame, the first drive unit being used to drive the first swing arm to rotate horizontally relative to the support frame; an adsorption block is connected to a second end of the first swing arm.

[0010] Driven by the moving component, the adsorption block picks up the label from the printing mechanism and moves it into place along the first horizontal direction. Then, the first driving unit drives the first swing arm to rotate horizontally toward the manifold to be labeled. This drives the adsorption block to rotate to the manifold, so that the adsorption block can affix the picked-up label to the manifold.

[0011] In some embodiments, the swing arm assembly further includes a second drive unit and a second swing arm, wherein: a first end of the second swing arm is rotatably connected to a second end of the first swing arm and is drively connected to a second drive unit disposed on the first swing arm, the second drive unit being used to drive the second swing arm to rotate relative to the second end of the first swing arm; and an adsorption block is connected to the second end of the second swing arm.

[0012] Driven by the moving component, the adsorption block picks up the label from the printing mechanism and moves it into position along the first horizontal direction. First, the first driving unit drives the first swing arm to rotate horizontally towards the busbar to be labeled, rotating the adsorption block near the busbar. Then, the second driving unit drives the second swing arm to continue rotating horizontally towards the busbar, ultimately ensuring the adsorption block accurately reaches the busbar. In other words, through the cooperation of the first and second swing arms, the swing arm assembly increases the range of movement of the adsorption block in the horizontal plane, enabling this application to be compatible with battery packs of various sizes and ensuring that the adsorption block can be accurately rotated to the busbar.

[0013] In some embodiments, the first driving unit includes a first driving member and a first rotating shaft, wherein the first rotating shaft is rotatably mounted on a support frame, the first end of the first swing arm is fixedly connected to the first rotating shaft, the first driving member is disposed on the support frame, and the driving end of the first driving member is drively connected to the first rotating shaft. The first driving member is used to drive the first rotating shaft to rotate, thereby driving the first swing arm to rotate. The second driving unit includes a second driving member, a driving pulley, a driven pulley, a timing belt, and a second rotating shaft, wherein: the second driving member is disposed on the first swing arm, the driving pulley is fixedly connected to the driving shaft of the second driving member, the second rotating shaft is rotatably mounted on the second end of the first swing arm, the driven pulley is fixedly connected to the second rotating shaft, the first end of the second swing arm is fixedly connected to the second rotating shaft, the timing belt is sleeved on the driving pulley and the driven pulley, and the second driving member drives the second rotating shaft to rotate via the driving pulley, the timing belt, and the driven pulley, thereby driving the second swing arm to rotate horizontally.

[0014] By configuring the first and second drive units, the first drive unit can independently and stably drive the first swing arm to rotate relative to the support frame, and the second drive unit can independently and stably drive the second swing arm to rotate relative to the first swing arm. Furthermore, since the first drive unit is mounted on the support frame, and the second drive unit is located at the first end of the first swing arm and close to the support frame, the center of gravity of the swing arm assembly is close to the support frame, thereby improving the rotational stability of the swing arm assembly and preventing the adsorption block from sagging.

[0015] In some embodiments, the labeling mechanism further includes a flip drive assembly disposed at the second end of the swing arm assembly, and the adsorption block is connected to the movable part of the flip drive assembly; the flip drive assembly is used to drive the adsorption block to flip vertically so that the adsorption surface of the adsorption block faces downward to pick up the label, and to flip the adsorption block and the picked-up label upward.

[0016] The printed label inside the printing mechanism has its printed side facing up and its adhesive side facing down. By setting up a flipping drive component, the adsorption block can pick up the printed side of the label with the adsorption side facing down, then flip the label so that the adhesive side faces up, and finally affix the label to the busbar on the lower surface of the battery string.

[0017] In some embodiments, an air cavity is provided inside the adsorption block, and a plurality of adsorption holes communicating with the air cavity are provided on the adsorption surface of the adsorption block; an air extraction hole is provided inside the flip drive assembly and connected to the air cavity, the air extraction hole is used to be rotatably connected to the air pipe of the air extraction device, and the air extraction device is used to extract air from the air cavity so that the adsorption holes generate adsorption force.

[0018] By configuring the adsorption block, it can absorb and release labels. Furthermore, by using an air extraction port connected to the air chamber within the adsorption block in the flip drive assembly, the air tube can draw air from the air chamber of the adsorption block through the air extraction port on the flip drive assembly, thus preventing the air tube from twisting during adsorption block flipping.

[0019] In some embodiments, the moving component includes a translation drive and a lifting drive, wherein: the lifting drive is connected to a movable part of the translation drive, and the support frame is connected to the movable part of the lifting drive; the translation drive is used to drive the support frame to translate along a first horizontal direction, and the lifting drive is used to drive the support frame to lift.

[0020] By coordinating the translation drive and the lifting drive, the moving component can flexibly adjust the position of the support frame in the first horizontal and vertical directions.

[0021] In some embodiments, the translation drive includes a first mounting plate, a first motor, and a first synchronous belt, wherein: a first slide rail extending along a first horizontal direction is provided on the first mounting plate; the first synchronous belt is mounted on the first mounting plate and parallel to the first slide rail; the lifting drive is slidably connected to the first slide rail and connected to one side of the first synchronous belt; the first motor is disposed on the first mounting plate and is used to drive the first synchronous belt to convey, so as to drive the lifting drive to translate along the first slide rail.

[0022] A simple and stable translation drive is provided, which can drive a lifting drive to translate stably along a first horizontal direction.

[0023] In some embodiments, the lifting drive includes a second mounting plate, a second motor, and a second synchronous belt, wherein: the second mounting plate is connected to a movable part of the translation drive, and a second slide rail extending in a vertical direction is provided on the second mounting plate; the second synchronous belt is mounted on the second mounting plate and parallel to the second slide rail, and a support frame is slidably connected to the second slide rail and connected to one side of the belt body of the second synchronous belt; the second motor is disposed on the second mounting plate, and the second motor is used to drive the second synchronous belt to convey, so as to drive the support frame to lift and lower along the second slide rail.

[0024] A simple and stable lifting drive component is provided, which can drive the support frame to lift stably.

[0025] This application also provides a photovoltaic module production equipment, which includes a conveying mechanism, a handling mechanism, a printing mechanism, and a labeling mechanism as described in any one of the above, wherein:

[0026] The conveying mechanism is configured to receive the backplate and transport it to the assembly station;

[0027] The transport mechanism is configured to transport the battery string packs above the assembly station;

[0028] The printing mechanism is located on the side of the assembly station and is used to print labels.

[0029] The labeling mechanism is configured to pick up labels from the printing mechanism and affix the labels to the busbars on the lower surface of the battery string packs that are being transported to the assembly station.

[0030] The handling mechanism is also configured to place the battery packs with labels affixed onto the backplate.

[0031] This application provides photovoltaic module production equipment, in which the labeling mechanism and printer are set up independently and both are located close to the assembly station. When the conveying mechanism transports the backsheet to the assembly station and the handling mechanism moves the battery string group above the backsheet, the labeling mechanism can pick up the label from the printer and affix the label to the busbar on the lower surface of the battery string group. Subsequently, the handling mechanism stacks the battery string group on the backsheet.

[0032] As can be seen, the photovoltaic module production equipment provided in this application simultaneously completes the labeling action during the process of stacking the battery strings onto the backsheet. Therefore, there is no need to set up an additional labeling station or to perform additional lifting and lowering operations on the battery strings, thereby saving equipment space, speeding up the work cycle, improving the production efficiency of photovoltaic modules, and reducing the risk of the battery strings being damaged.

[0047] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] like Figures 1 to 3 As shown, the labeling mechanism 10 in this embodiment includes a moving component 1, a support frame 2, a swing arm assembly 3, and an adsorption block 4, wherein:

[0049] The support frame 2 is connected to the movable part of the moving component 1, the first end of the swing arm assembly 2 is rotatably connected to the support frame 2, and the adsorption block 4 is connected to the second end of the swing arm assembly 3.

[0050] The adsorption block 4 is used to pick up the label from the printing mechanism, the moving component 1 is used to drive the adsorption block 4 to translate along a first horizontal direction (such as the X direction) and to drive the adsorption block 4 to rise and fall, and the swing arm component 4 is used to drive the adsorption block 4 to swing in the horizontal plane.

[0051] The optional working process of the labeling mechanism 10 in this embodiment is as follows.

[0052] The moving component 1 first drives the swing arm component 2 and the suction block 4 to move in the first horizontal direction toward the printing mechanism, so that the suction block 4 can pick up the printed label from the printing mechanism.

[0053] Subsequently, the moving component 1 drives the swing arm component 2 and the suction block 4 to move away from the printing mechanism, so that the suction block 4 approaches the busbar of the label to be applied on the back of the battery string.

[0054] Next, the swing arm assembly 4 drives the adsorption block 4 to rotate horizontally toward the manifold until the adsorption block 4 is directly below the manifold.

[0055] Finally, the moving component 1 drives the swing arm component 2 and the adsorption block 4 to rise, so that the adsorption block 4 affixes the label to the manifold.

[0056] As can be seen, the labeling mechanism 10 of this embodiment is independently configured with respect to the label printer. Therefore, it can be positioned on the transport path of the backplate conveying mechanism. When the transport mechanism transports the battery packs to be stacked to the top of the backplate, the labeling mechanism can affix labels to the busbars on the lower surface of the battery packs. Subsequently, the transport mechanism stacks the battery packs onto the backplate.

[0057] In other words, by using the labeling mechanism provided in this application embodiment, the labeling action can be completed during the process of the transport mechanism stacking the battery string group onto the back sheet. Therefore, there is no need to set up an additional labeling station or to perform additional lifting and lowering operations on the battery string group, thereby saving equipment space, speeding up the work cycle, improving the production efficiency of photovoltaic modules, and reducing the risk of the battery string group being damaged.

[0058] like Figure 1 and Figure 2 As shown, the swing arm assembly 3 includes a first drive unit 31 and a first swing arm 32. The first end of the first swing arm 32 is rotatably connected to the support frame 2 and is drively connected to the first drive unit 31 mounted on the support frame 2. The first drive unit 31 is used to drive the first swing arm 32 to rotate horizontally relative to the support frame 2. The adsorption block 4 is connected to the second end of the first swing arm 32.

[0059] Driven by the moving component 1, the adsorption block 4 picks up the label from the printing mechanism and moves it into position along the first horizontal direction. The first driving unit 31 drives the first swing arm 32 to rotate horizontally toward the manifold, thereby rotating and driving the adsorption block 4 to the manifold, so that the adsorption block 4 can affix the picked-up label to the manifold.

[0060] The adsorption block 4 can be directly mounted on the second end of the first swing arm 32. In this case, the first swing arm 32 directly drives the adsorption block 4 to the busbar by rotation. Since the length of the first swing arm 32 is fixed, it is necessary to ensure that the busbar is on the rotation path of the second end of the first swing arm 32. That is to say, the swing arm assembly 3 of this structure can only perform labeling on battery strings of a specific size, and its versatility is low.

[0061] Continue to refer to, for example Figure 1 and Figure 2As shown, optionally, the swing arm assembly 3 further includes a second drive unit 33 and a second swing arm 34, wherein: the first end of the second swing arm 34 is rotatably connected to the second end of the first swing arm 32 and is drively connected to the second drive unit 33 disposed on the first swing arm 32, and the second drive unit 33 is used to drive the second swing arm 34 to rotate relative to the second end of the first swing arm 32. The adsorption block 4 is connected to the second end of the second swing arm 34. That is, the adsorption block 4 is indirectly connected to the second end of the first swing arm 32 through the second swing arm 34, and the second swing arm 34 can drive the adsorption block 4 to rotate relative to the second end of the first swing arm 32.

[0062] Driven by the moving component 1, the adsorption block 4 picks up the label from the printing mechanism and moves it into position along the first horizontal direction. First, the first drive unit 31 drives the first swing arm 32 to rotate horizontally toward the manifold, driving the adsorption block 4 to the vicinity of the manifold to be labeled. Then, the second drive unit 33 drives the second swing arm 34 to continue rotating horizontally toward the manifold, ultimately ensuring that the adsorption block 4 accurately reaches the manifold.

[0063] In other words, through the cooperation of the first rotating arm 32 and the second rotating arm 34, the swing arm assembly 3 increases the range of movement of the adsorption block 4 in the horizontal plane, thereby enabling the swing arm assembly 3 to be compatible with battery string groups of more sizes and ensuring that the adsorption block 4 can be accurately rotated to the busbar.

[0064] like Figures 2 to 3 As shown, optionally, the first drive unit 31 includes a first drive member 311 and a first rotating shaft 312, wherein the first rotating shaft 312 is rotatably mounted on the support frame 2, the first end of the first swing arm 32 is fixedly connected to the first rotating shaft 312, the first drive member 311 is disposed on the support frame 2, the drive end of the first drive member 311 is connected to the first rotating shaft 312 for transmission, and the first drive member 311 is used to drive the first rotating shaft 312 to rotate so as to drive the first swing arm 32 to rotate.

[0065] The second drive unit 33 includes a second drive member 331, a drive pulley 332, a driven pulley 333, a timing belt 334, and a second rotating shaft 335. The second drive member 331 is mounted on the first swing arm 32. The drive pulley 332 is fixedly connected to the drive shaft of the second drive member 331. The second rotating shaft 335 is rotatably mounted on the second end of the first swing arm 32. The driven pulley 333 is fixedly connected to the second rotating shaft 335. The first end of the second swing arm 34 is fixedly connected to the second rotating shaft 335. The timing belt 334 is sleeved on the drive pulley 332 and the driven pulley 333. The second drive member 331 drives the second rotating shaft 335 to rotate via the drive pulley 332, the timing belt 334, and the driven pulley 333, thereby causing the second swing arm 34 to rotate horizontally.

[0066] By configuring the first drive unit 31 and the second drive unit 33, the first drive unit 31 can independently and stably drive the first swing arm 32 to rotate relative to the support frame 2, and the second drive unit 33 can independently and stably drive the second swing arm 34 to rotate relative to the first swing arm 32. Furthermore, since the first drive member 311 is mounted on the support frame 2, and the second drive member 331 is located at the first end of the first swing arm 32 and close to the support frame 2, the center of gravity of the swing arm assembly 3 is close to the support frame 2, thereby improving the rotational stability of the swing arm assembly 3 and preventing the adsorption block 4 from sagging.

[0067] Both the first drive component 311 and the second drive component 331 can be motors.

[0068] Generally, labels printed in the printing mechanism have the printed side facing up and the adhesive side facing down. To allow the suction block 4 to pick up the printed side of the label, the label is flipped over so the adhesive side is facing up and then affixed to the busbar on the lower surface of the battery string. Optionally, such as... Figures 1 to 3 As shown, the labeling mechanism in this embodiment of the application further includes a flip drive component 5, which is disposed at the second end of the swing arm component 3, and the adsorption block 4 is connected to the movable part of the flip drive component 5.

[0069] The flipping drive assembly 5 is used to drive the adsorption block 4 to flip vertically, so that the adsorption surface of the adsorption block 4 faces down to pick up the label, and to flip the adsorption block 4 and the picked-up label to face up, thereby ensuring that the adhesive surface of the label faces up and is attached to the busbar on the lower surface of the battery string.

[0070] The flip drive assembly 5 may include, for example, a flip drive motor and a flip plate. The flip drive motor is located at the second end of the swing arm assembly 3, the flip plate is connected to the drive end of the flip drive motor, and the adsorption block 4 is located at the end of the flip plate. The flip drive motor drives the flip plate to flip vertically, thereby causing the adsorption block 4 to flip synchronously.

[0071] like Figures 2 to 3 As shown, optionally, the adsorption block 4 is provided with an air cavity, and the adsorption surface of the adsorption block 4 is provided with a plurality of adsorption holes 41 communicating with the air cavity. The flip drive assembly 5 is provided with an air extraction hole 51 that penetrates the flip drive assembly 5 and is connected to the air cavity. The air extraction hole 51 is used to rotatably connect with the air pipe of the air extraction device, and the air extraction device is used to extract air from the air cavity through the air extraction hole 51 so that the adsorption holes 41 generate adsorption force.

[0072] By configuring the adsorption block 4, it is possible to absorb and release the label. Furthermore, by using the air extraction hole 51 connected to the air chamber within the adsorption block 4 in the flip drive assembly 5, the air tube can draw air from the air chamber within the adsorption block through the air extraction hole on the flip drive assembly 5, thus preventing the air tube from twisting when the adsorption block 4 is flipped.

[0073] like Figure 1 As shown, optionally, the moving component 1 includes a translation drive 11 and a lifting drive 12, wherein: the lifting drive 11 is connected to the movable part of the translation drive 11, and the support frame 2 is connected to the movable part of the lifting drive 12. The translation drive 11 is used to drive the support frame 2 to translate along a first horizontal direction, and the lifting drive 12 is used to drive the support frame 2 to rise and fall.

[0074] Optionally, the translation drive 11 includes a first mounting plate 111, a first motor 112, and a first synchronous belt 113, wherein: the first mounting plate 111 is provided with a first slide rail extending in a first horizontal direction. The first synchronous belt 113 is mounted on the first mounting plate 111 and is parallel to the first slide rail. The lifting drive 12 is slidably connected to the first slide rail and connected to one side of the first synchronous belt 113 (e.g., the lower side of the belt). The first motor 112 is disposed on the first mounting plate 111 and is used to drive the first synchronous belt 113 to convey, thereby driving the lifting drive 12 to translate along the first slide rail.

[0075] Of course, the translation drive 11 can also be a linear drive module with other known structures, as long as it can drive the lifting drive 12 to translate along the first horizontal direction, such as a lead screw drive module.

[0076] Optionally, the lifting drive component 12 includes a second mounting plate 121, a second motor 122, and a second synchronous belt, wherein: the second mounting plate 121 is connected to the movable part of the translation drive component 11, and a second slide rail extending vertically is provided on the second mounting plate. The second synchronous belt is mounted on the second mounting plate 121 and parallel to the second slide rail, and the support frame 2 is slidably connected to the second slide rail and connected to one side of the second synchronous belt. The second motor 122 is disposed on the second mounting plate 121, and the second motor 122 is used to drive the second synchronous belt to convey, thereby driving the support frame 2 to rise and fall along the second slide rail.

[0077] Of course, the lifting drive unit 12 can also adopt other known linear drive modules, as long as they can drive the support frame 2 to lift, such as a screw drive module.

[0078] Based on the same concept, this application also provides photovoltaic module manufacturing equipment. For example... Figure 4 As shown, the photovoltaic module production equipment in this embodiment includes a conveying mechanism 20, a handling mechanism (not shown in the figure), a printing mechanism 30, and a labeling mechanism 10 in any of the above embodiments.

[0079] The conveying mechanism 20 is configured to receive the back plate 100 and to convey the back plate 100 to the assembly station.

[0080] The transport mechanism is configured to transport the battery string 200 above the assembly station.

[0081] The printing mechanism 30 is located on the side of the assembly station and is used to print labels.

[0082] The labeling mechanism 10 is configured to pick up a label from the printing mechanism 30 and affix the label to the busbar on the lower surface of the battery string 200 being transported to the assembly station.

[0083] The handling mechanism is also configured to place the battery string 200 with the labels affixed onto the backplate 100.

[0084] In the photovoltaic module production equipment of this application embodiment, the labeling mechanism 10 and the printer 30 are independently set, and both are located close to the assembly station. When the conveying mechanism 20 conveys the back sheet 100 to the assembly station, and the handling mechanism moves the battery string group 200 above the back sheet, the labeling mechanism 10 can pick up the label from the printer 30 and affix the label to the busbar on the lower surface of the battery string group 200. Subsequently, the handling mechanism stacks the battery string group onto the back sheet 100.

[0085] As can be seen, the photovoltaic module production equipment of this application embodiment completes the labeling action simultaneously during the process of stacking the battery string group 200 onto the back sheet 100. Therefore, there is no need to set up an additional labeling station or to perform additional lifting and lowering operations on the battery string group, thereby saving equipment space, speeding up the work cycle, improving the production efficiency of photovoltaic modules, and reducing the risk of the battery string group 20 being damaged.
