Description

[Technical Field]

[0001] This utility model belongs to the field of material handling equipment technology, and in particular relates to a flipping mechanism and a flipping material handling device. [Background Technology]

[0002] Strip profiles are used in many products, such as window frames, photovoltaic module frames, and panel edging frames. After cutting, drilling, and chamfering, strip profiles need to be stacked into a three-dimensional structure and then bundled with straps for easy handling and transportation. A palletizer is an automated device that can stack profiles according to a certain arrangement to form a profile stack.

[0003] Currently, the frames used on photovoltaic modules need to be stacked together with their front and back sides interlocked during palletizing and packaging. Therefore, the frames need to be flipped 180 degrees during palletizing, which requires the use of a flipping mechanism.

[0004] Existing patent CN221758893U discloses a strip-shaped frame fastening and palletizing device, which includes a frame conveyor line, frame fastening mechanisms disposed on both sides of the frame conveyor line, a palletizing station disposed at the end of the frame conveyor line, and a palletizing and transporting mechanism for transporting a group of frames from the frame conveyor line to the palletizing station for palletizing. The device conveys frames with their openings facing upwards through the frame conveyor line, and then uses the frame fastening mechanism to lift one of two adjacent frames, flip it 180 degrees, and fasten it onto the other frame to form a frame group with the frames fastened together. Then, the frame conveyor line buffers multiple frame groups into a row, and the palletizing and transporting mechanism transports the entire row of frame groups to the palletizing station for palletizing. In this process, the flipping and transporting of the frames are completed by two mechanisms, and the frames need to be flipped and fastened one by one. The feeding speed of the frame group is slow, which seriously affects the palletizing cycle.

[0005] To accommodate higher palletizing cycles, this solution proposes integrating the handling and flipping mechanisms, incorporating the frame flipping action within the palletizing and handling mechanism to improve palletizing efficiency. Existing patent CN119218698A discloses a high-efficiency photovoltaic frame aluminum flipping device, which uses two relative flipping and fastening mechanisms to clamp a group of frames for flipping. With the increasing demand for higher palletizing cycles, the palletizing and handling mechanism needs to handle a larger number of frames at a time to achieve the set cycle. If the aforementioned flipping device is directly integrated into the frame palletizing device, the palletizing and handling mechanism requires a larger flipping radius as the number of frames handled at once increases. Therefore, after clamping multiple frames from the frame conveyor line, the palletizing and handling mechanism needs to rise to a higher height to achieve synchronous flipping of all frames. The more frames flipped in a row at once, the longer the lifting and lowering stroke, thus limiting the improvement in palletizing cycle.

[0006] Therefore, it is necessary to provide a new flipping mechanism and flipping conveying device to solve the above-mentioned technical problems. [Utility Model Content]

[0007] One of the main objectives of this utility model is to provide a flipping mechanism, which provides a completely new structure to solve the above-mentioned technical problems.

[0008] This utility model achieves the above objective through the following technical solution: a flipping mechanism, comprising:

[0009] Mounting bracket;

[0010] At least two flipping modules are arranged on the mounting bracket. Each flipping module has a pair of flipping clamps and a first motor that drives the flipping clamps to rotate. Each pair of flipping clamps can hold two sets of materials and flip them around the flipping axis of their respective flipping clamps. The flipping axes of two adjacent flipping modules are parallel to each other and located on the same horizontal plane.

[0011] Furthermore, the flipping module includes a second motor fixed on the mounting bracket and a movable bracket that moves horizontally driven by the second motor; the movable brackets in the two flipping modules move closer together to clamp the material or separate to release the material under the drive of the second motor.

[0012] Furthermore, the first motor is fixedly mounted on the movable bracket; the flipping clamp is rotatably mounted on the movable bracket and connected to the rotating end of the first motor.

[0013] Furthermore, the two movable supports in the flipping module are driven by a second motor to move closer to each other or separate from each other; or each is driven by a second motor to move horizontally.

[0014] Furthermore, in the two flipping modules, the clamping height of the two pairs of flipping clamps is consistent.

[0015] Furthermore, the flipping clamp includes a mounting plate and a limiting clamp mounted on the mounting plate; the limiting clamp is provided with a limiting slot; both ends of the material extend into the limiting slot to achieve fixed limiting.

[0016] Furthermore, the limiting clamp includes a base plate and a limiting pressure plate located above the base plate, and the limiting groove is formed between the base plate and the limiting pressure plate.

[0017] Furthermore, the outer edge of the base plate protrudes beyond the outer edge of the limiting pressure plate.

[0018] Another objective of this utility model is to provide a flipping and conveying device, which includes a drive mechanism and a flipping mechanism as described above, disposed at the movable end of the drive mechanism, wherein the mounting bracket is disposed at the movable end of the drive mechanism.

[0019] Furthermore, the driving mechanism is a Z-axis driving module, an XZ-axis driving module, a YZ-axis driving module, or an XYZ-axis driving module.

[0020] Compared with the prior art, the advantages of the flipping mechanism and flipping transport device of this utility model are as follows: a flipping mechanism is set on the frame transport support, integrating transport and flipping functions, realizing the flipping of the frame during the frame transport process, and improving the stacking efficiency of frame materials; at least two flipping modules are arranged side by side on the transport support, and compared with the original flipping mechanism, the flipping radius required to flip the same number of frames is smaller, so it can effectively reduce the lifting stroke when the frame is flipped, and has a greater advantage in improving the frame stacking cycle.

Detailed Implementation Methods

[0032] Example 1:

[0033] Please refer to Figures 1-7 This embodiment is a flipping and handling device 100, which includes a driving mechanism 1 and a flipping mechanism 2 disposed at the active end of the driving mechanism 1; it can be used as a palletizing and handling mechanism for a frame palletizing device, and can flip the entire set of frames as needed during the frame handling process.

[0034] The drive mechanism 1 can be selected from one of the Z-axis drive module, XZ-axis drive module, YZ-axis drive module, or XYZ-axis drive module, and the drive mechanism 1 can be flexibly designed according to the material handling path. The drive mechanism 1 realizes the positional movement of the frame between the feeding position and the stacking position.

[0035] The flipping mechanism 2 includes a mounting bracket 21 located at the movable end of the drive mechanism 1 and at least two flipping modules 22 arranged side by side on the mounting bracket 21. The two flipping modules 22 can clamp two sets of frames and flip them around their respective flipping axes. Compared with the original single flipping module clamping the same number of frames for overall flipping, the flipping radius can be reduced by nearly half, thereby reducing the working height when the frames are flipped. Therefore, the height travel of the drive mechanism 1 driving the flipping mechanism 2 to clamp the frames and the height travel of the palletizing mechanism to descend can be reduced, thereby improving the palletizing cycle time and meeting the requirements of higher production efficiency.

[0036] In this embodiment, two flip modules 22 are provided on the mounting bracket 21. In other embodiments, three, four or more flip modules 22 may also be provided.

[0037] The flipping module 22 includes a pair of movable brackets 221 arranged opposite each other on the mounting bracket 21 along the length of the frame, and a second motor 222 fixed on the mounting bracket 21 and driving the movable brackets 221 to move horizontally. Each movable bracket 221 is provided with a first motor 223 and a flipping clamping plate 224 driven by the first motor 223 to rotate. The flipping clamping plates 224 on the two movable brackets 221 form a pair of clamping components that clamp the two ends of the frame and flip around the flipping axis O' of the flipping clamping plate 224. The second motor 222 drives the movable brackets 221 to move horizontally, causing the two movable brackets 221 to move closer to each other, thereby driving the flipping clamping plate 224 to clamp the two ends of the frame. The first motor 223 drives the flipping clamping plate 224 to clamp the frame and realize the flipping action.

[0038] In this embodiment, two second motors 222 are provided, each driving one of the two movable supports 221 to move horizontally independently. In other embodiments, only one second motor 222 may be provided, which, together with the transmission assembly, enables the two movable supports 221 to move horizontally synchronously, completing the action of moving closer or apart from each other.

[0039] In this embodiment, the flipping clamp 224 has a set length in the frame arrangement direction so as to be able to clamp multiple frames at once, and to clamp multiple frames arranged continuously. In the two flipping modules 22, the clamping height of the two pairs of flipping clamps 224 is consistent so as to be able to clamp multiple frames located at the same horizontal height. For example, if several frames are transported by the frame conveyor line, the system will divide them into two groups, use the two flipping modules 22 to clamp the two groups of frames, and flip the two groups of frames according to process requirements.

[0040] Since the frame needs to be flipped 180 degrees during the stacking process, to prevent the flipped frame from falling off the flip clamp 224, this embodiment optimizes the structure of the flip clamp 224. Specifically, the flip clamp 224 includes a mounting plate 2241 and a mounting clamp 2242 mounted on the mounting plate 2241. The limiting clamp 2242 includes a base plate 2242a and a limiting pressure plate 2242b located above the base plate 2242a. A limiting slot 2242c is formed between the base plate 2242a and the limiting pressure plate 2242b. Because the frame needs to be combined with other frames to form a rectangular frame structure, the ends of the frame are generally cut at an angle, forming a triangular pointed cone B. For the short frame in the photovoltaic module, in order to achieve fastening assembly with the adjacent long frame, a corner bracket is also installed at both ends of the short frame, such as... Figure 7As shown. When the flip clamp 224 clamps the frame, the bottom of the frame rests on the base plate 2242a, and the triangular cone B extends into the limiting slot 2242c. At the same time, the end of the limiting pressure plate 2242b presses against the right angle side of the corner bracket and the hypotenuse C of the triangular cone B. At this time, the vertical direction of the frame is restricted. Therefore, even if the frame is flipped 180 degrees, the frame will not fall off the flip clamp 224 due to the existence of the limiting slot 2242c structure, thus ensuring the reliability of the frame flipping.

[0041] The working principle of the flipping and conveying device 100 in this embodiment is as follows: A row of frame pieces is conveyed to the feeding position. After the frame pieces are positioned and the two ends are aligned, the drive mechanism 1 drives the flipping mechanism 2 to descend to the height of the frame pieces. The second motor 222 drives the flipping clamp 224 to move towards the frame pieces. The two sets of flipping clamps 224 divide the row of frame pieces into two for clamping. Each flipping module 22 clamps one set of frame pieces. If the row of frame pieces does not need to be flipped, the drive mechanism 1 directly drives the flipping mechanism 2 to move the frame pieces to the stacking position for stacking. If the row of frame pieces needs to be flipped, the drive mechanism 1 drives the flipping mechanism 2 to rise to the flipping height. The first motor 223 drives the flipping clamp 224 to rotate around their respective flipping axis O'. Then, the two sets of frame pieces also rotate 180 degrees around their respective corresponding flipping axis O' and are then moved to the stacking position and stacked upside down on the top frame piece.

[0042] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
