Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module packaging technology, and in particular relates to an automatic cover-loading device. Background Technology

[0002] In the production process of photovoltaic (PV) modules, the finished modules need to be packaged and transported. Currently, PV modules are stacked in multiples, strapped together, and then packaged in cardboard boxes. Before strapping, a cover needs to be placed on top of the PV modules to protect the top surface and the corners where the top and sides of the stacked modules meet. However, because the size of multiple stacked PV modules is very large, the size of the cover used for protection is correspondingly large. Generally, multiple people work together to install the cover before strapping and packaging. However, manually installing the cover requires bending it before it can be installed on the PV modules, resulting in low work efficiency, a large amount of manual labor, and high labor costs.

[0003] In existing technologies, automatic lid placement is achieved by first bending the lid and then attaching it using a robotic arm. For example, Chinese Patent Publication CN219468100U discloses an automatic lid-attaching device for packaging photovoltaic modules, which includes a first roller conveyor line and a second roller conveyor line connected to each other. A ground rail is provided on one side along the conveying direction of the first roller conveyor line, and a handling robot is mounted on the ground rail. Multiple shelves are provided on the side of the ground rail away from the first roller conveyor line. The end effector of the handling robot is connected to a gripping and pressing mechanism to grip and press the edge of the lid, thereby pressing the edge of the lid along its fold line. The device automatically places and folds the covers, improving efficiency compared to manual labor. However, it has several drawbacks: The handling robot moves the covers from multiple shelves directly onto the photovoltaic modules and then presses the edges of the covers along their fold lines. If the covers on the shelves are misaligned, the fold lines will also shift, preventing the folding process from being completed smoothly. Furthermore, the use of rubber rollers during bending prevents them from successfully completing the folding process if the fold lines shift.

[0004] Therefore, it is necessary to provide an automatic cover-attaching device to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this utility model is to provide an automatic cover-attaching device that can ensure the accuracy of the cover folding process, avoid misalignment of the folding edge or product damage caused by positioning deviation, improve the quality of the folding edge, and adapt to cover of different sizes, thus improving versatility.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: an automatic cover-loading device, comprising a feeding unit, a calibration unit, a conveying unit disposed on one side of the calibration unit, a belt-pressing unit disposed at one end of the conveying unit, and a conveying and folding unit for transporting the cover and performing an edge-folding action on the cover; the calibration unit includes a support platform for carrying the cover and a straightening mechanism disposed on the support platform for straightening the cover around its perimeter; the conveying and folding unit includes a gripper for grasping the cover and an edge-folding mechanism disposed on the gripper for folding the cover.

[0007] Furthermore, the calibration mechanism includes a left calibration plate for calibrating the left side of the top cover, a right calibration plate for calibrating the right side of the top cover, a front calibration plate for calibrating the front side of the top cover, and a rear calibration plate for calibrating the rear side of the top cover. A calibration area is provided on the support platform, and the left calibration plate, the front calibration plate, the right calibration plate, and the rear calibration plate are arranged around the calibration area.

[0008] Furthermore, the left alignment plate and / or the right alignment plate are driven to move left and right by the first driving member.

[0009] Furthermore, the front and rear alignment plates are driven by a single alignment drive module to move simultaneously toward or away from the top cover; the alignment drive module includes a first motor mounted on the support platform and a transmission belt driven by the first motor for forward and backward transmission.

[0010] Furthermore, the gripper includes a mounting frame, a first sensor disposed below the mounting frame, and several suction cups.

[0011] Furthermore, the folding mechanism includes a first cylinder and a folding piece that is driven by the first cylinder to move up and down.

[0012] Furthermore, the longitudinal section of the folding piece has an "L" shaped structure. The folding piece includes a horizontal plate that presses against the edge of the upper cover and a vertical plate connected to the horizontal plate. When the folding action is performed, the bottom of the vertical plate is aligned with the fold line of the upper cover.

[0013] Furthermore, the folding mechanism is movably mounted on the gripper.

[0014] Furthermore, the feeding unit is equipped with several brushes for cleaning the sides of the top cover and a second sensor for detecting whether there is material.

[0015] Furthermore, the tape-tapping unit includes a vertical tape-tapping mechanism and / or a horizontal tape-tapping mechanism.

[0016] Compared with the prior art, the advantages of this utility model's automatic cover-loading device are as follows: (1) A calibration unit is provided. Before folding, the calibration unit’s correction mechanism first corrects the four sides of the top cover. Through the coordinated action of the left correction plate, right correction plate, front correction plate and rear correction plate, the top cover is accurately corrected on all four sides, which can ensure the accuracy of the top cover folding process and avoid folding misalignment or product damage caused by positioning deviation. (2) The left and / or right alignment plates are driven by the first driving component to move left and right, so that the position of the left and / or right alignment plates can be flexibly adjusted to adapt to the top cover of different widths; the front and rear alignment plates are driven by a single alignment driving module to move closer to or further away from the top cover, so that the position of the front and rear alignment plates can be flexibly adjusted to adapt to the top cover of different lengths; therefore, the alignment mechanism can adapt to top covers of different sizes and improve versatility. (3) The “L” shaped folding part design of the folding mechanism can improve the quality of folding. Specifically, the vertical plate of the folding part can accurately align with the fold line to ensure accurate folding position. The horizontal plate of the folding part presses against the edge of the upper surface of the cover to prevent the edge of the cover from warping or deforming, thereby improving the quality of folding. (4) The folding mechanism is movable and can be adapted to top covers of different sizes, which can expand the scope of application of this solution; (5) Multiple suction cups can be selected from several suction cups to form an adsorption assembly according to the specific size of the cover. The layout of the adsorption assembly matches the length and width of the cover, enabling it to adsorb covers of different length and width. It can adapt to covers of different length and width, improving the versatility of the gripper. Attached Figure Description

Detailed Implementation

[0018] Please refer to Figures 1-6 This embodiment is an automatic cover-loading device 100, which includes a feeding unit 1, a calibration unit 2, a conveying unit 3 disposed on one side of the calibration unit 2, a belt-pressing unit 4 disposed at one end of the conveying unit 3, and a conveying and folding unit 5 for transporting the cover 200 and performing an edge-folding action on the cover 200; the calibration unit 2 includes a support platform 21 for supporting the cover 200 and a straightening mechanism 22 disposed on the support platform 21 for straightening the cover 200 around its perimeter; the conveying and folding unit 5 includes a gripper 51 for gripping the cover 200 and an edge-folding mechanism 52 disposed on the gripper 51 for folding the cover 200 around its perimeter.

[0019] The alignment mechanism 22 includes a left alignment plate 221 for aligning the left side of the top cover 200, a right alignment plate 222 for aligning the right side of the top cover 200, a front alignment plate 223 for aligning the front side of the top cover 200, and a rear alignment plate 224 for aligning the rear side of the top cover 200. A calibration area 211 is provided on the support platform 21. The left alignment plate 221, right alignment plate 222, front alignment plate 223, and rear alignment plate 224 are arranged around the calibration area 211. The alignment mechanism 22 first calibrates the top cover 200, ensuring the accuracy of the top cover folding process and avoiding folding misalignment or product damage caused by positioning deviations.

[0020] There are several left alignment plates 221, right alignment plates 222, front alignment plates 223, and rear alignment plates 224. The specific number of these plates is adjusted according to the size of the top cover and is not limited here.

[0021] In this embodiment, the left alignment plate 221 is fixedly mounted on the support platform 21, and the right alignment plate 222 is driven by the first driving member 225 to move left and right. The right alignment plate 222 is mounted on the first driving member 225 via the first moving frame 227. The first driving member 225 drives the right alignment plate 222 to move to the left, while the left side of the upper cover 200 abuts against the left alignment plate 221, thereby realizing the left and right alignment action of the upper cover 200.

[0022] In other embodiments, the right alignment plate 222 is fixedly mounted on the support platform 21, and the left alignment plate 221 is driven by the first driving member 225 to move left and right. The first driving member 225 drives the left alignment plate 221 to move to the right, while the right side of the upper cover 200 abuts against the right alignment plate 222, thereby realizing the left and right alignment action of the upper cover 200.

[0023] In another embodiment, the left straightening plate 221 and the right straightening plate 222 are both driven by the first driving member 225 to move left and right. The left straightening plate 221 and the right straightening plate 222 simultaneously approach the upper cover 200 to achieve the left and right straightening action of the upper cover 200.

[0024] In this embodiment, the first driving component 225 is a cylinder. To improve the versatility of the alignment mechanism 22 and adapt to top covers of different widths, the cylinder is movably positioned left and right to allow for flexible adjustment of the positions of the left alignment plate 221 and / or the right alignment plate 222. The movably positioned cylinder is mounted on the support platform 21 via a slider rail and is locked with screws. When it is necessary to adjust the positions of the left alignment plate 221 and / or the right alignment plate 222, the screws are loosened, the positions of the left alignment plate 221 and / or the right alignment plate 222 are adjusted, and then the screws are tightened again.

[0025] In other embodiments, the first driving component 225 is a servo motor. The servo motor can automatically adjust the left and right positions of the left alignment plate 221 and / or the right alignment plate 222. When changing the top cover 200 of different sizes, the position can be switched with one key in the control system, making it more convenient to adjust the left and right positions of the left alignment plate 221 and / or the right alignment plate 222.

[0026] In this embodiment, the front alignment plate 223 and the rear alignment plate 224 are driven by a single alignment drive module 226 to move simultaneously closer to or further away from the top cover 200. The alignment drive module 226 includes a first motor 2261 mounted on a support platform 21 and a transmission belt 2262 driven by the first motor 2261 for forward and backward transmission. The front alignment plate 223 and the rear alignment plate 224 are both mounted on the transmission belt 2262 via a second movable frame 228, and achieve alignment action with the transmission belt 2262. The first motor 2261 can not only drive the front alignment plate 223 and the rear alignment plate 224 to move back and forth to achieve alignment action, but also automatically adjust the front and rear positions of the front alignment plate 223 and / or the right alignment plate 224. When changing the top cover 200 of different lengths, the position can be switched with one key in the control system, making the adjustment of the front and rear positions of the front alignment plate 223 and / or the right alignment plate 224 more convenient.

[0027] The support platform 21 is provided with a first slide rail, and the first movable frame 227 and the second movable frame 228 are both slidably mounted on the support platform 21 via the first slider.

[0028] The handling and folding unit 5 also includes a robot 53, with a gripper 51 located at the movable end of the robot 53. The gripper 51 includes a mounting frame 511, a first sensor 512 located below the mounting frame 511, and several suction cups 513. The robot 53 drives the gripper 51 to descend. When the first sensor 512 contacts the surface of the upper cover 200, the first sensor 512 sends a signal to cause the several suction cups 513 to adhere to the upper cover 200.

[0029] Several suction cups 513 are mounted on the mounting bracket 511. The layout of the suction cups 513 is set according to the actual situation and is not limited here. Moreover, multiple suction cups 513 can be selected to form an adsorption assembly according to the specific size of the top cover 200 to perform adsorption. The layout of the adsorption assembly matches the length and width dimensions of the top cover 200, which can perform adsorption on top covers 200 with different length and width dimensions, and can adapt to top covers 200 with different length and width dimensions, thus improving the versatility of the gripper 51.

[0030] In this embodiment, folding is required on the left and right sides of the top cover 200. Therefore, folding mechanisms 52 are provided on both the left and right sides of the mounting frame 511. Since the top cover 200 is relatively long, two folding mechanisms 52 are provided on each side of the mounting frame 511, and the folding mechanisms 52 on both sides of the mounting frame 511 are arranged opposite each other to ensure the stability and accuracy of the folding. In other embodiments, the position and number of folding mechanisms 52 can be adjusted according to the actual situation. For example, if folding is required on the front and back sides of the top cover 200, folding mechanisms 52 are provided on both the front and back sides of the mounting frame 511. Since the front and back sides of the top cover 200 are relatively short, one folding mechanism 52 is sufficient on each side of the mounting frame 511. If the front and back sides of the top cover 200 are relatively large, the number of folding mechanisms 52 is increased accordingly. Therefore, the position and number of folding mechanisms 52 can be adjusted according to the actual situation and are not limited here.

[0031] The folding mechanism 52 includes a first cylinder 521 and a folding member 522 driven by the first cylinder 521 to move up and down. The longitudinal section of the folding member 522 is "L" shaped. The folding member 522 includes a horizontal plate 5221 that presses against the edge of the upper cover and a vertical plate 5222 connected to the horizontal plate 5221. During the folding action, the bottom of the vertical plate 5222 is aligned with the fold line of the upper cover 200. When the first cylinder 521 drives the folding member 522 to move downward, the vertical plate 5222 is pressed down along the fold line to bend its edge downward, and the horizontal plate 5221 is pressed against the upper edge of the upper cover, thus realizing the folding action of the upper cover 200. During the folding process, the bottom of the vertical plate 5222 is aligned with the fold line of the upper cover 200 to ensure the accuracy of the subsequent folding position. The horizontal plate 5221 is pressed against the upper edge of the upper cover, applying a positive pressure to the edge of the upper cover 200. The pressing of the edge by the horizontal plate 5221 can prevent the edge of the upper cover from warping or deforming, and can also enable the vertical plate 5222 to better perform the downward pressing action, thereby improving the quality of the folding.

[0032] In this embodiment, since the width of the top cover 200 is consistent and only the length varies, the fold lines of the top cover 200 are consistent, so the folding mechanism 52 is fixedly set.

[0033] In other embodiments, if the widths of the top covers 200 are inconsistent, i.e., the fold lines of the top covers 200 are not aligned, the folding mechanism 52 is movably configured to improve the versatility of the automatic top cover mounting device 100. The movably configured folding mechanism 52 is mounted on the gripper 51 via a slider rail and secured with screws. When the position of the folding mechanism 52 needs adjustment, the screws are loosened; after adjustment, the screws are tightened again. The movably configured folding mechanism 52, mounted on the gripper 51 via a slider rail, is automatically adjusted in position using a servo motor, allowing for one-button switching in the control system when changing top covers of different sizes.

[0034] The feeding unit 1 has three enclosures, forming a space for storing and stacking the top covers 200. Within this space are several brushes 11 for cleaning the sides of the top covers 200 and a second sensor 12 for detecting the presence of material. The brushes 11 extend vertically and are positioned opposite each other. During feeding, the brushes 11 automatically clean the edges of the top covers 200, preventing impurities from affecting the folding or adsorption effect. In this embodiment, two feeding units 1 are arranged side-by-side. The length and width dimensions of the enclosure spaces of the two feeding units 1 can be the same or different, depending on the actual situation. If the length and width dimensions of the two enclosure spaces are the same, dual-station feeding can be achieved, improving feeding efficiency. If the length and width dimensions of the two enclosure spaces are different, feeding of top covers of different sizes can be achieved, reducing equipment changeover time and improving the versatility of the automatic top cover loading device 100. In other embodiments, the feeding unit 1 can also be one, three, or other quantities, depending on the actual space size, and is not limited here.

[0035] The conveying unit 3 includes a conveyor line 31 and alignment modules 32 disposed on the left and right sides of the conveyor line 31. The conveyor line 31 is used to convey packing boxes containing photovoltaic modules. The alignment modules 32 synchronously align the left and right sides of the packing box to ensure that the packing box is centered and aligned during the conveying process, providing accurate positioning for subsequent strapping and reducing packaging errors. A third sensor 33 for detecting the position of the packing box is also provided on the conveyor line 31. In this embodiment, two alignment modules 32 are disposed opposite each other on the left and right sides of the conveyor line 31 to ensure the accuracy of alignment. In other embodiments, the number of alignment modules 32 can be set according to the specific size of the packing box.

[0036] The correction module 32 includes a correction component 321 and a correction drive component 322 that drives the correction component 321 to move left and right.

[0037] In this embodiment, since the packing box contains a stack of photovoltaic modules, which are relatively heavy, the conveyor line 31 is a roller conveyor line. Its structure is existing technology and will not be described in detail here. In other embodiments, if the packing box contains other lighter products, the conveyor line 31 can be set as a belt conveyor line or other conveyor line structures. The specific structure of the conveyor line 31 is not limited here, as long as it is designed for heavy goods such as photovoltaic modules and ensures conveying stability.

[0038] In this embodiment, the strapping unit 4 includes a vertical strapping mechanism for performing vertical strapping operations on the packing box.

[0039] In other embodiments, the strapping unit 4 includes a transverse strapping mechanism for performing transverse strapping operations on the packing box.

[0040] In another embodiment, the strapping unit 4 includes a vertical strapping mechanism and a horizontal strapping mechanism, which sequentially perform vertical strapping and horizontal strapping operations on the packing box.

[0041] The structure of the vertical belt-pressing mechanism is already known in the prior art and will not be described in detail here; the existing structure will suffice.

[0042] When using the automatic cover-loading device 100 provided in this solution, the stacked covers 200 are placed in the enclosure space of the feeding unit 1. The robot 53 drives the gripper 51 to move to the feeding unit 1, and several suction cups 513 on the gripper 51 adhere to the covers 200. The robot 53 drives the gripper 51 to transport the adhered covers 200 to the support platform 21. The first driving component 225 drives the right alignment plate 222 to move to the left, and at the same time, the left side of the covers 200 abuts against the left alignment plate 221, realizing the left and right alignment of the covers 200. Simultaneously, the first motor 2261 drives the front alignment plate 223 and the rear alignment plate 224 to move back and forth to approach the side of the covers 200, realizing the front and rear alignment, thus completing the process. The four sides of the top cover 200 are aligned. After alignment, the left alignment plate 221, right alignment plate 222, front alignment plate 223, and rear alignment plate 224 are reset. At this time, a packing box containing photovoltaic modules flows into the conveying unit 3. The robot 53 drives the gripper 51 to move above the conveying unit 3 and positions the top cover 200 on the top of the packing box. When the first cylinder 521 drives the folding piece 522 to move downward, the vertical plate 5222 presses down along the fold line to make its edge bend downward. The horizontal plate 5221 presses against the upper edge of the top cover to realize the folding action of the top cover 200. After the folding is completed, the packing box continues to be conveyed forward. The belt-tying unit 4 performs belt-tying operation on it. After the belt-tying is completed, it enters the next workstation for subsequent operations.

[0043] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
