Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module production equipment, and in particular to a tray flipping device. Background Technology

[0002] Wooden pallets are commonly used in the production and transportation of photovoltaic modules to facilitate their handling and storage. However, to save space and increase transport volume, wooden pallets are often stacked upside down during transport. Therefore, before using wooden pallets on the production line, the pallets with the reverse side facing up need to be manually flipped over, increasing labor costs and posing safety hazards. Utility Model Content

[0003] Therefore, it is necessary to provide a pallet flipping device to address the problem that wooden pallets facing up need to be manually flipped before being used on the production line, which increases labor costs and poses safety hazards.

[0004] The technical solution is as follows:

[0005] On one hand, a pallet flipping device is provided, comprising:

[0006] The support body includes a first guide rail and a second guide rail. The first guide rail is provided with a clearance station, a flipping station and a loading station arranged sequentially from top to bottom. One end of the second guide rail is connected to the first guide rail and is located between the clearance station and the flipping station. The other end of the second guide rail is provided with a unloading station.

[0007] A first suction module is installed at the loading station and is capable of moving along the first guide rail and the second guide rail. The first suction module is configured to suction the tray when it is located at the loading station and to selectively flip the tray when it is located at the flipping station.

[0008] A second suction module is installed at the avoidance station and is movable along the first guide rail and the second guide rail. The second suction module is configured to move toward the flipping station after the first suction module flips the tray in order to pick up the tray on the first suction module.

[0009] The pallet flipping device in the above embodiments has a front-side working mode and a back-side working mode. When the front side of the pallet below the first suction module is facing up, the pallet flipping device activates the front-side working mode. First, the first suction module moves downwards along the first guide rail to pick up the pallet; then, the first suction module moves the pallet along the first and second guide rails to the unloading station; finally, the first suction module releases the pallet and resets. When the back side of the pallet below the first suction module is facing up, the pallet flipping device activates the back-side working mode. First, the first suction module moves downwards along the first guide rail to pick up the pallet; second, the first suction module moves the pallet upwards along the first guide rail to the flipping station; then, the first suction module flips the pallet so that the front side of the pallet faces up; next, the second suction module moves towards the flipping station to pick up the pallet on the first suction module. At this time, the first suction module releases the pallet and, through the second suction module, moves the pallet along the first and second guide rails to the unloading station; finally, the second suction module releases the pallet, and the first and second suction modules reset. This application uses a first suction module and a second suction module to flip a tray that is upside down back to its original position, reducing human intervention, lowering labor costs, meeting the needs of large-scale automated production lines, and also reducing safety risks during the tray flipping process, thereby improving the safety of the production line.

[0010] The technical solution will be further explained below:

[0013] In one embodiment, the first suction mechanism includes a first mounting body, a first telescopic member, and a suction cup. The first mounting body is convexly connected to the flipping mechanism. The number of the first telescopic member and the suction cup is at least one. Each suction cup is correspondingly mounted on the bottom of each first telescopic member. Each first telescopic member is mounted on the bottom of the first mounting body and correspondingly drives each suction cup to rise and fall.

[0014] In one embodiment, the first suction module further includes a clamping mechanism mounted on the first suction mechanism and configured to clamp and engage with the tray when the first suction mechanism picks up the tray.

[0015] In one embodiment, the clamping mechanism includes two driving members and two clamping members. The two clamping members are located on opposite sides of the bottom of the first suction mechanism. The two driving members are respectively mounted on opposite sides of the first suction mechanism and are correspondingly connected to the two clamping members in a transmission manner, so as to drive the two clamping members to move in a direction that is closer to or further away from each other.

[0016] In one embodiment, the second suction module includes a second moving mechanism capable of moving along the first guide rail and the second guide rail, and a second suction mechanism mounted on the second moving mechanism, the second suction mechanism being used to suction the tray.

[0017] In one embodiment, the first guide rail extends vertically, the end of the second guide rail near the first guide rail extends horizontally, and the end of the second guide rail away from the first guide rail extends downward and is parallel to the first guide rail.

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] like Figure 1As shown, in one embodiment, a pallet flipping device 10 is provided, including a support body 100, a first suction module 200, and a second suction module 300. The support body 100 includes a first guide rail 110 and a second guide rail 120. The first guide rail 110 has a clearance station, a flipping station, and a loading station arranged sequentially from top to bottom. One end of the second guide rail 120 is connected to the first guide rail 110 and located between the clearance station and the flipping station; the other end of the second guide rail 120 has a unloading station. The first suction module 200 is installed at the loading station and is movable along the first guide rail 110 and the second guide rail 120. The first suction module 200 is configured to suction the pallet when located at the loading station and selectively flip the pallet when located at the flipping station. The second suction module 300 is installed at the clearance station and is movable along the first guide rail 110 and the second guide rail 120. The second suction module 300 is configured to move toward the flipping station after the first suction module 200 flips the tray, in order to pick up the tray on the first suction module 200.

[0028] The pallet flipping device 10 in the above embodiment has a front working mode and a back working mode. When the front of the pallet below the first suction module 200 is facing up, the pallet flipping device 10 starts the front working mode. That is, firstly, the first suction module 200 moves downward along the first guide rail 110 to pick up the pallet; then, the first suction module 200 drives the pallet to move along the first guide rail 110 and the second guide rail 120 to the unloading station; finally, the first suction module 200 releases the pallet and resets. When the tray below the first suction module 200 is facing upwards, the tray flipping device 10 activates the reverse working mode. First, the first suction module 200 moves downwards along the first guide rail 110 to pick up the tray. Second, the first suction module 200 moves the tray upwards along the first guide rail 110 to the flipping station. Then, the first suction module 200 flips the tray so that its front faces upwards. Next, the second suction module 300 moves towards the flipping station to pick up the tray from the first suction module 200. At this point, the first suction module 200 releases the tray, and the second suction module 300 moves the tray along the first guide rail 110 and the second guide rail 120 to the unloading station. Finally, the second suction module 300 releases the tray, and the first and second suction modules reset. This application uses the cooperation of the first suction module 200 and the second suction module 300 to flip the tray from facing upwards back to its original position, reducing manual intervention, lowering labor costs, meeting the needs of large-scale automated production lines, and also reducing safety risks during the tray flipping process, thus improving the safety of the production line.

[0029] The avoidance station refers to a position on the first guide rail 110 that ensures the second suction module 300 will not interfere with the first suction module 200 during its movement from the loading station to the unloading station. The flipping station refers to a position on the first guide rail 110 that ensures the first suction module 200 will not interfere with the second suction module 300 above it or the pallet at the loading station during the flipping process caused by the first suction module 200.

[0030] Specifically, in this embodiment, pallets stacked in a forward and reverse manner can be transported to the loading station by a loading trolley, ensuring that the first suction module 200 at the loading station can move downward along the first guide rail 110 to pick up the pallets. When the first suction module 200 releases the pallet at the unloading station, or when the second suction module 300 releases the pallet at the unloading station, the pallet is placed on the unloading trolley at the unloading station and pulled away by the unloading trolley for use.

[0031] like Figure 1 As shown, optionally, the pallet flipping device 10 also includes a detection module 400. The detection module 400 is communicatively connected to both the first suction module 200 and the second suction module 300, and is used to detect the orientation of the pallet at the loading station. Thus, the detection module 400 can identify the orientation of the pallet at the loading station and accurately control the pallet flipping device 10 to start either a front-facing working mode or a back-facing working mode based on the pallet's orientation. This ensures that the pallet flipping device 10 does not flip pallets facing forward, and flips back pallets facing backward to their correct position. The entire process is fully automatic, requiring no manual intervention, reducing labor intensity, improving production line efficiency, and ensuring the safety of the pallet flipping operation.

[0032] The detection module 400 can be configured as a camera detection structure, an infrared sensor detection structure, or other structure capable of detecting whether the tray is facing up or down. The detection module 400 can communicate with the first suction module 200 and the second suction module 300 via data cable, power cable, Bluetooth, wireless network communication technology, or other means. Specifically, in this embodiment, the detection module 400 is installed at the bottom of the first suction module 200. In other embodiments, the detection module 400 can also be installed independently of the first suction module 200, for example, on the first guide rail 110.

[0033] Specifically, in this embodiment, when the pallet flipping device 10 is in use, the detection module 400 detects whether there is a pallet at the loading station. If the detection module 400 does not detect a pallet at the loading station, it sends a material shortage signal to the host computer. The host computer then sends an instruction to the loading trolley based on the material shortage signal, causing the loading trolley to automatically transport the pallet from the designated area to the loading station. If the detection module 400 detects a pallet at the loading station, it then detects the orientation of the uppermost pallet at the loading station and controls the pallet flipping device 10 to start either the front-facing working mode or the back-facing working mode based on the pallet's orientation.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, the first suction module 200 includes a first moving mechanism 210 movable along a first guide rail 110 and a second guide rail 120, a flipping mechanism 220 mounted on the first moving mechanism 210, and a first suction mechanism 230 pulsatorically connected to the flipping mechanism 220. The flipping mechanism 220 drives the first suction mechanism 230 to flip. The first suction mechanism 230 is used to suction the tray. Thus, the first moving mechanism 210 can drive the flipping mechanism 220 and the first suction mechanism 230 to move along the first guide rail 110 and the second guide rail 120. The flipping mechanism 220 can selectively drive the first suction mechanism 230 to flip 180°, thereby synchronously driving the tray to flip back to the correct position through the first suction mechanism 230, improving the reliability of the tray flipping device 10.

[0035] The first moving mechanism 210 can be configured as any existing structure capable of moving on the first guide rail 110 and the second guide rail 120. The flipping mechanism 220 can be configured as any existing structure capable of driving the first suction mechanism 230 to flip 180°. The first suction mechanism 230 can be configured as any existing structure capable of suctioning both the front and back of the tray. Specifically, in this embodiment, the first moving mechanism 210 and the flipping mechanism 220 are integrated. The flipping mechanism 220 includes a rotating shaft for transmission connection with the first suction mechanism 230.

[0036] like Figure 2As shown, optionally, the first suction mechanism 230 includes a first mounting body 231, a first telescopic member 232, and a suction cup 233. The first mounting body 231 is connected to the flipping mechanism 220 via a transmission connection. The number of the first telescopic member 232 and the suction cup 233 is at least one. Each suction cup 233 is correspondingly mounted on the bottom of each first telescopic member 232. Each first telescopic member 232 is mounted on the bottom of the first mounting body 231 and correspondingly drives each suction cup 233 to rise and fall. Thus, each first telescopic member 232 can adjust the position of each suction cup 233 relative to the first mounting body 231, ensuring that each suction cup 233 can pick up the front or back of the tray and drive the tray to move, improving the reliability of the tray flipping device 10.

[0037] The number of the first telescopic component 232 and the number of suction cups 233 can be flexibly adjusted according to actual usage needs.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, the first suction module 200 further includes a clamping mechanism 240. The clamping mechanism 240 is mounted on the first suction mechanism 230 and configured to clamp and engage with the pallet when the first suction mechanism 230 suctions the pallet. Thus, the clamping mechanism 240 can improve the fixing strength between the pallet and the first suction mechanism 230, reduce the risk of the pallet falling during movement, and improve the reliability of the pallet flipping device 10.

[0039] like Figure 2 As shown, optionally, the clamping mechanism 240 includes two driving members 241 and two clamping members 242. The two clamping members 242 are located on opposite sides of the bottom of the first suction mechanism 230. The two driving members 241 are respectively mounted on opposite sides of the first suction mechanism 230 and are correspondingly connected to the two clamping members 242 for transmission, so as to drive the two clamping members 242 to move in a direction that approaches or moves away from each other. In this way, while the first suction mechanism 230 is suctioning the tray, the two driving members 241 respectively drive the two clamping members 242 to move in a direction that approaches each other until the two opposing clamping members 242 clamp the tray, ensuring that the tray is stably and reliably fixed on the first suction mechanism 230.

[0040] The clamping member 242 can be configured as a clamping plate, clamping claw, or other clamping member 242. The two driving members 241 can move closer to or further away from each other by driving the two clamping members 242 to rotate, or by driving the two clamping members 242 to translate. The driving member 241 can be configured as a rotary cylinder, rotary motor, telescopic cylinder, telescopic rod, or other driving structure.

[0041] The structure and shape of the second suction module 300 may be the same as or different from those of the first suction module 200.

[0042] Optionally, the second suction module 300 includes a second moving mechanism 310 movable along the first guide rail 110 and the second guide rail 120, and a second suction mechanism 320 mounted on the second moving mechanism 310. The second suction mechanism 320 is used to suction the tray. Thus, the second suction module 300 may not include the flipping mechanism 220, reducing the manufacturing cost of the tray flipping device 10.

[0043] like Figure 1 As shown, in one embodiment, the first guide rail 110 extends vertically. The end of the second guide rail 120 near the first guide rail 110 extends horizontally. The end of the second guide rail 120 away from the first guide rail 110 extends downward and is parallel to the first guide rail 110. Thus, both the first suction module 200 and the second suction module 300 can move smoothly on the first guide rail 110 and the second guide rail 120, improving the reliability and stability of the tray flipping device 10.

[0044] In other embodiments, the first guide rail 110 may also be inclined. The shape of the second guide rail 120 can also be flexibly adjusted according to actual usage needs.

[0045] like Figure 1 As shown, in one embodiment, the pallet flipping device 10 further includes a straightening module 500. The straightening module 500 is installed at the unloading station and configured to straighten the pallet after the first suction module 200 moves the pallet to the unloading station and releases it, or after the second suction module 300 moves the pallet to the unloading station and releases it. Thus, the straightening module 500 ensures that each pallet at the unloading station is correctly positioned, improving the convenience of subsequent operations.

[0046] The correction module 500 can be configured as any structure in the prior art capable of correcting the position of the tray.

[0047] like Figure 1As shown, optionally, the alignment module 500 includes a second mounting body 510, a third mounting body 520, a second telescopic member 530, a third telescopic member 540, a first alignment member 550, and a second alignment member 560. The second mounting body 510 and the third mounting body 520 are respectively mounted on opposite sides of the unloading station. The second telescopic member 530 and the third telescopic member 540 are respectively mounted on the side of the second mounting body 510 and the third mounting body 520 that are close to each other. The second telescopic member 530 and the third telescopic member 540 are respectively connected to the first alignment member 550 and the second alignment member 560 in a driving connection, so that both the first alignment member 550 and the second alignment member 560 can align the pallet. Thus, when the first suction module 200 or the second suction module 300 releases the pallet at the unloading station, the pallet is placed between the first straightening component 550 and the second straightening component 560. The first straightening component 550 can straighten one side of the pallet under the drive of the second telescopic component 530, and the second straightening component 560 can straighten the other side of the pallet under the drive of the third telescopic component 540, ensuring that the pallet is correctly positioned and improving the practicality of the pallet flipping device 10.

[0048] The number of the second telescopic component 530, the third telescopic component 540, the first straightening component 550, and the second straightening component 560 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, there are two of each of the second and third telescopic components 530, and both are configured as telescopic rods. There are also two of each of the first and second straightening components 550 and 560, and both are configured as straightening baffles. The four telescopic rods are symmetrically and spaced apart on the side of the second mounting body 510 and the third mounting body 520 that are close to each other. The four straightening baffles are respectively installed at the ends of the four telescopic rods that are in a suspended state.

[0049] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0050] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0053] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0054] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
