Description

Technical Field

[0001] This invention belongs to the technical field of photovoltaic profile palletizing equipment, and in particular relates to a profile palletizing equipment and method. Background Technology

[0002] Photovoltaic frames are an important component of photovoltaic equipment. After the frames are manufactured, they are stacked together for transportation. To facilitate subsequent frame assembly, corner brackets are installed at both ends of the frames. During stacking, to save space, one frame is flipped and misaligned to press on the other frame. In order to prevent friction and scratches between the two frames, a layer of paper is placed between them before they are flipped and snapped together. This process is called the frame stacking process.

[0003] To achieve efficient automated palletizing of photovoltaic frames, existing patent CN119873397A discloses an automated photovoltaic frame palletizing device, which includes a conveying mechanism, a truss gripper mechanism, and an upper corner paper stacking mechanism. Through the cooperation of a feeding synchronous belt and a clamping frame, it achieves efficient conveying, flipping, and palletizing of photovoltaic frames, ensuring continuous paper strips. However, this device has the following drawbacks:

[0004] (1) The equipment occupies a large space, which is not conducive to use scenarios with limited space;

[0005] (2) The equipment is equipped with a palletizing station and a feeding station. The frame flipping and palletizing are integrated into a truss gripper mechanism. The conveying mechanism transports a row of frames to the feeding station. The truss gripper mechanism clamps them at the feeding station, flips them, and then fastens them to the newly entered row of frames to complete the front and back fastening. Then the frames that are fastened together are clamped from the feeding station to the palletizing station. Only after the palletizing is completed and the truss gripper mechanism returns to the feeding station can the next cycle of frame flipping and fastening and palletizing operation be carried out. The overall cycle is slow and the efficiency is low, which cannot meet the palletizing requirements of higher cycle.

[0006] (3) In this equipment, the flipping center of the flipping mechanism in the truss gripper mechanism is fixed. The geometric center of the frame group conveyed to the feeding synchronous belt must be consistent with the flipping center so that the frame group can be effectively engaged with the next row of frames after flipping 180°. However, if the overall width of the entire row of frames in the stack changes, although the geometric center of the entire row of frames can be kept unchanged by adjusting the position of the blocking and straightening module on the feeding synchronous belt, the position of the corner code paper needs to be adjusted. The main thing is to adjust the position of the tail end of the corner code paper after it is pulled out. The adjustment is inconvenient and time-consuming.

[0007] Therefore, it is necessary to provide a new profile palletizing equipment and method to solve the above-mentioned technical problems. Summary of the Invention

[0008] One of the main objectives of this invention is to provide a profile palletizing device that can efficiently realize the front and back snapping of profiles, inserting corner clips, inserting release paper, and automatic palletizing, with fast cycle time, high efficiency, and small equipment space occupation.

[0009] The present invention achieves the above objective through the following technical solution: a profile palletizing device, comprising:

[0010] The conveying mechanism includes a buffer conveyor line that conveys profiles along the X direction to the forward and reverse interlocking paper-filling station, and a front alignment component and a rear alignment component that align the profile groups on both sides of the buffer conveyor line in the X direction.

The first alignment roller is located at the movable end of the second cylinder and moves up and down driven by the second cylinder.

[0011] The flipping paper-feeding mechanism includes two sub-modules respectively disposed on both sides of the forward and reverse paper-feeding station in the Y direction. Each sub-module includes a second driving member, a bracket driven by the second driving member to move along the Y direction, a flipping module disposed on the bracket and facing the forward and reverse paper-feeding station, and a corner code paper-feeding module disposed on the bracket and located on one side of the flipping module in the Y direction. The flipping module includes a third driving member fixed on the bracket, a third support plate driven by the third driving member to move up and down, a fourth driving member fixed on the third support plate, a flipping plate driven by the fourth driving member to flip around the Y axis, a profile clamping plate fixed on the surface of the flipping plate facing the forward and reverse paper-feeding station and used to support the end of the profile, and a pair of alignment clamping components disposed on the flipping plate and used to perform X-direction position alignment clamping on the profile group sitting on the profile clamping plate.

[0012] Furthermore, the bracket has a supporting facade facing the paper-clamping station, and the supporting facade has a through window extending through both sides in the Y direction; the third support plate moves up and down on the supporting facade and avoids the through window when it moves to the highest position.

[0013] Furthermore, the alignment clamping assembly is adjustablely positioned on the flip plate along the X direction; and includes a fourth cylinder and an alignment clamping plate that is driven by the fourth cylinder to move along the X direction.

[0014] Furthermore, the corner code spacer feeding and inserting module and the forward and reverse interlocking inserting station are located on both sides of the flipping module in the Y direction, and include a corner code spacer feeding component mounted on the bracket, a corner code spacer pulling component that pulls the corner code spacer in the corner code spacer feeding component out a set length in the X direction, a corner code spacer clamping component that is set along the corner code spacer pulling out section and is used to clamp the corner code spacer, a corner code spacer cutting component that is set close to the corner code spacer feeding component and cuts the corner code spacer after it is pulled out a set length, and a transfer component that drives the corner code spacer clamping component to move in space to place the corner code spacer.

[0015] Furthermore, the corner code paper clamping assembly includes a fifth support plate and a plurality of second gripper assemblies arranged at intervals along the X direction on the fifth support plate;

[0016] The transfer assembly includes a sixth cylinder fixed on the bracket, a sixth support plate driven by the sixth cylinder to move up and down, and a seventh cylinder fixed on the sixth support plate. The fifth support plate is slidably disposed on the sixth support plate along the Y direction and is driven by the seventh cylinder to move along the Y direction.

[0017] The corner code paper pulling assembly includes a fifth driving member fixed on the bracket, a fourth support plate driven by the fifth driving member to move in the X direction, and a first gripper assembly fixed on the fourth support plate.

[0018] Furthermore, a feeding station, a paper-insertion station, and a stacking station are sequentially arranged along the X direction; the profile stacking equipment also includes a stacking and transporting mechanism for transporting the profiles with the snap-fitted edges from the paper-insertion station to the stacking station for stacking, and a release paper placement mechanism set at the stacking station.

[0019] Furthermore, the conveying mechanism also includes a material distribution conveyor line whose conveying range covers the feeding station, a first alignment module disposed on both sides of the material distribution conveyor line in the Y direction and for aligning the positions of the profiles at both ends in the Y direction, a material distribution module for controlling the profiles entering the material distribution conveyor line, and a blocking module for blocking the profiles on the output side of the material distribution conveyor line; the buffer conveyor line is disposed connected to the material distribution conveyor line and its conveying range covers the positive and negative snap-fit ​​paper-plugging station.

[0020] Another object of the present invention is to provide a profile palletizing method, implemented based on the above-mentioned profile palletizing equipment, which includes the following steps:

[0021] S1. The distance between the rotation center of the flipping module and the cutting position of the corner code paper end in the corner code paper feeding and inserting module is denoted as L1, and the overall width of the profile group is denoted as L1 + L2; the first driving member drives the second straightening roller to move to the adjustment position, which is a position L2 away from the rotation center of the flipping module.

[0022] S2. The profiles enter the buffer conveyor line one by one. When the buffer reaches a set number, a first positive profile group is obtained. The first positive profile group has two ends, A and B, and the second alignment roller is abutted at end B.

[0023] S3. The profile clamping plate in the flipping module lifts the first positive profile group from the bottom of both ends AB and raises the first positive profile group to a high position. At the same time, the pair of straightening clamping components clamp the first positive profile group at both ends AB. Then the flipping plate flips 180° to flip the first positive profile group 180° to obtain the reverse profile group.

[0024] S4. The first driving component drives the second alignment roller to move to the initial position, which corresponds to the cutting position of the corner code paper end;

[0025] S5. The profiles enter the buffer conveyor line one by one. When the buffer reaches a set number, a second positive profile group is obtained. The second positive profile group has two ends, A and B, and the second alignment roller is abutted at end B.

[0026] S6. The first alignment roller moves along the X direction to align the position of end A of the second positive profile group;

[0027] S7. The corner code paper feeding and inserting module inserts corner code paper into both ends of the second positive profile group;

[0028] S8. The flipping module clamps the reverse profile group and lowers it, engaging with the second positive profile group below to obtain a positive and negative engaging profile group.

[0029] Further, step S7 includes: the corner code spacer feeding and inserting module includes a corner code spacer feeding component disposed on the bracket, a corner code spacer pulling component that pulls the corner code spacer in the corner code spacer feeding component out a set length in the X direction, a corner code spacer clamping component disposed along the corner code spacer pulling out section and used to clamp the corner code spacer, a corner code spacer cutting component disposed near the corner code spacer feeding component and cuts the corner code spacer after it is pulled out a set length, and a transfer component that drives the corner code spacer clamping component to move in space to realize the placement of the corner code spacer;

[0030] The corner code spacer feeding assembly continuously supplies strip-shaped corner code spacers; the corner code spacer pulling assembly pulls the corner code spacer from the head of the corner code spacer in the X direction for a set length; the corner code spacer clamping assembly clamps the pulled-out corner code spacer; the corner code spacer cutting assembly cuts the corner code spacer at the tail end; the transfer assembly drives the corner code spacer clamping assembly to move, driving the corner code spacer to pass under the flipping module and be placed at the designated positions at both ends A and B of the second positive profile group, thus completing the placement of the corner code spacer.

[0031] Compared with existing technologies, the beneficial effects of the profile palletizing equipment and method of the present invention are as follows: through integrated design and precise control mechanism, the high efficiency, precision and universality of the profile palletizing process are achieved, with significant technical effects, as detailed below:

[0032] (1) Achieve precise snap-fit ​​of front and back edges to ensure stacking stability: Through the coordinated adjustment of the first cylinder and the first drive component in the second alignment module, the positions of the front alignment component and the rear alignment component can be dynamically adjusted according to the width of the edge group, so that the front edge group of different widths and the reverse edge group after flipping always keep the geometric center aligned, which completely solves the snap-fit ​​deviation problem caused by the change of edge group width, ensures that the front and back edges are snapped in a one-to-one correspondence, avoids edge misalignment, missing snap-fit ​​and other situations, and lays the foundation for the stability of subsequent stacking;

[0033] (2) Integrated flipping and paper-feeding functions to improve production efficiency: The flipping and paper-feeding mechanism flips the frame (180°) The system integrates functions such as flipping to achieve reverse rotation, corner code paper feeding, cutting, and placement. After the first set of forward borders is input into place, the flipping module can take it out from the buffer conveyor line and raise it to a high position for flipping. After the first set of forward borders is taken away by the flipping module, the next set of forward borders can be input. When the second set of forward borders is delivered into place, the first set of forward borders has completed a 180° flip to form a reverse border group. The flipping module can then perform the snapping of the forward and reverse borders. At the same time, the corner code paper feeding and inserting module can insert the corner code paper. Then, the stacking and transporting mechanism takes away the snapped borders for stacking. After the snapped borders are taken away, the next cycle of border input, flipping, corner code paper insertion, and snapping can begin. Compared with the existing technology, the start of the next cycle does not have to wait for the stacking and transporting mechanism to return to the snapping and inserting paper station, thereby improving the equipment cycle time and production efficiency.

[0034] In addition, through the through-window design and the coordination of the transfer components, a clearance space can be formed when the flipping module performs the flipping action, and the corner code paper can be accurately inserted within the clearance space, reducing the process changeover time; at the same time, the independent control of the material distribution conveyor line and the buffer conveyor line and the pre-positioning of the alignment module enable the frame conveying, buffering and fastening operations to be carried out in parallel, which greatly shortens the processing cycle of a single frame and improves the overall production cycle.

[0035] (3) Enhance the versatility of the equipment and adapt to the processing of multiple frame specifications: The material distribution module can flexibly set the number of frames in each group. The second straightening module can adjust the position of the straightening component through the slide rail and the drive component. The straightening clamping component of the flipping module can be adjusted along the X direction and the length of the frame clamping plate covers a variety of conventional widths. The corner code paper pulling length can be automatically adjusted with the width of the frame group, so that the equipment can be adapted to a variety of different width specifications without major modifications, which significantly improves the adaptability of the equipment to diversified production needs.

[0036] In summary, this equipment, through the combination of structural innovation and intelligent control, significantly improves production efficiency and specification adaptability while ensuring the accuracy of frame fastening and palletizing quality, providing a reliable automated solution for large-scale, high-precision frame palletizing.

[0050] Example 1:

[0051] Please refer to Figures 1-8This embodiment is a profile palletizing equipment 100, which includes a feeding station, a front and back snapping paper-filling station and a palletizing station arranged sequentially along the X direction, a conveying mechanism 1 that conveys the frame from the feeding station to the front and back snapping paper-filling station, a flipping paper-filling mechanism 2 arranged on both sides of the front and back snapping paper-filling station in the Y direction, a palletizing and transporting mechanism 3 that transports the front and back snapped frame from the front and back snapping paper-filling station to the palletizing station for palletizing, and a separating paper placement mechanism 4 arranged at the palletizing station.

[0052] In this embodiment, the profile is a photovoltaic frame. In other embodiments, it can also be a profile structure for other application scenarios.

[0053] This embodiment designs a new frame stacking method, the general process of which is as follows: the conveying mechanism 1 conveys the forward frames to the forward and reverse interlocking paper-filling station; when a set quantity is reached, the flipping paper-filling mechanism 2 clamps the entire row of forward frames, lifts them upward and flips them 180° to obtain a set of reverse frames; the conveying mechanism 1 conveys the next set of forward frames to the forward and reverse interlocking paper-filling station. During this process, the flipping paper-filling mechanism 2 has prepared corner code spacers. After the next set of forward frames arrives, the corner code spacers are placed at the designated positions at both ends of the set of forward frames; the flipping paper-filling mechanism... 2. Move a set of reverse borders downwards and place them on a set of forward borders below to obtain a set of snap-fit ​​borders; the palletizing and transporting mechanism 3 then transports the set of snap-fit ​​borders from the forward and reverse snap-fit ​​paper-inserting station to the palletizing station for palletizing; at the palletizing station, the separating paper placement mechanism 4 completes the placement of the border separating paper according to requirements; during the palletizing process, the conveying mechanism 1 and the flipping paper-inserting mechanism 2 have started the next round of border conveying, forward and reverse snap-fitting, and corner code separating paper insertion, etc., repeating the above steps until the palletized borders reach the set height.

[0054] In this embodiment, the conveying mechanism 1 includes a material distribution conveying line 11 whose conveying range covers the feeding station, a buffer conveying line 12 whose conveying range covers the forward and reverse interlocking paper feeding station, a first alignment module 13 disposed on both sides of the material distribution conveying line 11 in the Y direction and for aligning the positions of the edges at both ends in the Y direction, a material distribution module 14 for controlling the material of the edges entering the material distribution conveying line 11, a blocking module 15 for blocking the edges on the output side of the material distribution conveying line 11, and a second alignment module 16 for aligning the positions of the edges on the buffer conveying line 12 in the X direction.

[0055] The material distribution conveyor line 11 and the buffer conveyor line 12 are each equipped with a servo motor to independently control the operation of their conveyor belts. The first alignment module 13 and the material distribution module 14 are located on the input side of the material distribution conveyor line 11. The material distribution module 14 is used to divide the incoming frame 200 into a group according to a set number (e.g., 1 to 8 pieces) and stop the frame 200 in the working area of ​​the first alignment module 13. The first alignment module 13 corrects the position of the frame at both ends in the Y direction and then conveys it to the buffer conveyor line 12 through the material distribution conveyor line 11. When the number of frames on the buffer conveyor line 12 reaches the set value, the blocking module 15 is activated to block the material distribution conveyor line 11 from conveying frames to the buffer conveyor line 12. At the same time, the second alignment module 16 corrects the position of the frame group on the buffer conveyor line 12 in the X direction, so that the subsequent flipping and feeding mechanism 2 can accurately clamp and flip all of them and achieve precise fastening.

[0056] The material distribution module 14 includes a front deflector assembly 141 and a rear deflector assembly 142 located upstream of the front deflector assembly 141 and spaced at a set distance. The specific structures of the first alignment module 13 and the material distribution module 14 can be referred to the structures of the "material distribution module" and "alignment module" in the existing patent CN119774063A, and will not be described again in this embodiment.

[0057] In this embodiment, the second alignment module 16 includes a rear alignment component 161 and a front alignment component 162 arranged opposite to each other along the X direction. The rear alignment component 161 includes a first cylinder 1611, a first support plate 1612 driven by the first cylinder 1611 to move along the X direction, a second cylinder 1613 fixed on the first support plate 1612, and a first alignment roller 1614 driven by the second cylinder 1613 to move up and down. The rear alignment component 161 is adjustablely positioned along the X direction on a first slide rail 1615, and its position in the X direction can be flexibly adjusted according to requirements to adapt to the alignment of borders of various widths.

[0058] The front alignment assembly 162 includes a first driving member 1621, a second support plate 1622 driven by the first driving member 1621 to move along the X direction, a third cylinder 1623 disposed on the second support plate 1622, and a second alignment roller 1624 driven by the third cylinder 1623 to move up and down. The front alignment assembly 162 achieves positional movement of the second alignment roller 1624 along the X direction by the first driving member 1621, making it suitable for aligning borders of various widths.

[0059] In this embodiment, the flipping and inserting paper mechanism 2 is the core mechanism of the device. It is used to realize the flipping of the frame, the feeding of corner code paper, and the insertion of corner code paper. It includes two sub-modules 20, which are respectively arranged on both sides of the forward and reverse interlocking paper inserting station in the Y direction. The sub-module 20 includes a second driving member 21, a bracket 22 driven by the second driving member 21 to move along the Y direction, a flipping module 23 arranged on the bracket 22 and facing the forward and reverse interlocking paper inserting station, and a corner code paper feeding and inserting module 24 arranged on the bracket 22 and located on one side of the flipping module 23 in the Y direction. The corner code paper feeding and inserting module 24 and the forward and reverse interlocking paper inserting station are located on both sides of the flipping module 23 in the Y direction.

[0060] The bracket 22 has a supporting facade (not shown in the figure) facing the forward and reverse interlocking paper feeding station. The supporting facade has a through window 221 extending through both sides in the Y direction. In this embodiment, the bracket 22 includes a horizontal supporting base 222, a pair of supporting columns 223 disposed on the horizontal supporting base 222, and a connecting beam 224 that pulls the tops of the pair of supporting columns 223 together. The space between the supporting columns 223 forms the through window 221 so that the corner code paper feeding module 24 can clamp the corner code paper 300, move it along the Y direction through the through window 221, and place it on the edge end of the buffer conveyor line 12.

[0061] The flipping module 23 includes a third drive member 231 fixed on the bracket 22, a third support plate 232 driven by the third drive member 231 to move up and down on the support column 223, a fourth drive member 233 fixed on the third support plate 232, a flipping plate 234 driven by the fourth drive member 233 to flip around the Y-axis, a frame clamping plate 235 fixed on the surface of the flipping plate 234 facing the positive and negative snapping paper feeding station and used to support the edge of the frame, and a pair of alignment clamping components 236 disposed on the flipping plate 234 and used to perform X-direction position alignment clamping on the frame group sitting on the frame clamping plate 235.

[0062] The flipping module 23 is movably mounted on the pair of support columns 223. When it is necessary to clamp and flip the frame on the buffer conveyor line 12, the third support plate 232 descends to a low position, and the two frame clamping plates 235 move closer to each other along the Y direction to clamp the frame. Then it rises to a set height and is driven by the fourth drive unit 233 to achieve a 180° flip of the frame. At the same time, it makes way for the corner code paper feeding and inserting module 24 to perform the corner code paper inserting operation.

[0063] To accommodate various width specifications of frame assemblies on the frame clamping plate 235, the alignment clamping assembly 236 is adjustable in position along the X direction on the flip plate 234. Specifically, the flip plate 234 is provided with a second slide rail 237, and the alignment clamping assembly 236 is slidably mounted on the second slide rail 237 and fixed by a fastener after being adjusted in position. The alignment clamping assembly 236 includes a fourth cylinder 2361 and an alignment clamping plate 2362 that is driven by the fourth cylinder 2361 to move along the X direction.

[0064] The corner code spacer feeding and inserting module 24 includes a corner code spacer feeding assembly 241 mounted on a bracket 22, a corner code spacer pulling assembly 242 that pulls the corner code spacer 300 in the corner code spacer feeding assembly 241 out a set length in the X direction, a corner code spacer clamping assembly 243 that is set along the corner code spacer pulling out section and is used to clamp the corner code spacer, a corner code spacer cutting assembly 244 that is set close to the corner code spacer feeding assembly 241 and cuts the corner code spacer after it is pulled out to the set length, and a transfer assembly 245 that drives the corner code spacer clamping assembly 243 to move in space to place the corner code spacer.

[0065] The corner code paper feeding assembly 241 is a conventional roll feeding assembly structure.

[0066] The corner code spacer paper pulling assembly 242 includes a fifth driving member 2421 fixed on the bracket 22, a fourth support plate 2422 driven by the fifth driving member 2421 to move along the X direction, and a first gripper assembly 2423 fixed on the fourth support plate 2422. The fifth driving member 2421 drives the first gripper assembly 2423 to clamp the end of the corner code spacer paper and pull it out along the X direction for a set length, thereby realizing the pulling of the paper.

[0067] The corner code spacer clamping assembly 243 includes a fifth support plate 2431 and a plurality of second gripper assemblies 2432 arranged at intervals along the X direction on the fifth support plate 2431. The second gripper assemblies 2432 are arranged along the corner code spacer pull-out direction and together clamp the corner code spacer 300.

[0068] The corner code spacer cutting assembly 244 includes a fifth cylinder 2441 and a pneumatic scissors 2442 driven by the fifth cylinder 2441 to move along the Y direction. The fifth cylinder 2441 drives the pneumatic scissors 2442 to move along the Y direction, realizing position switching between a waiting position and a working position. At the working position, the pneumatic scissors 2442 cuts the corner code spacer 300.

[0069] The transfer assembly 245 includes a sixth cylinder 2451 fixed on the bracket 22, a sixth support plate 2452 driven by the sixth cylinder 2451 to move up and down, and a seventh cylinder 2453 fixed on the sixth support plate 2452. A fifth support plate 2431 is slidably disposed on the sixth support plate 2452 along the Y direction and is driven by the seventh cylinder 2453 to move along the Y direction. The transfer assembly 245 enables the corner code paper clamping assembly 243 to move up and down as well as move in the Y direction.

[0070] Due to the diversity of palletizing borders, the width of a single border can vary. Consequently, when the number of border buffers of different widths reaches a set quantity, the overall width of the resulting border group will also be different, such as 1 meter, 1.1 meters, or 1.2 meters. However, in this embodiment, the position of the corner code paper cutting component 244 in the flipping paper feeding mechanism 2 is basically fixed. Therefore, the position of one end of the corner code paper is basically fixed. However, the length of the corner code paper pulled out can be automatically adjusted according to the width of the front row borders on the front and back interlocking paper feeding station. Therefore, in this embodiment, when the second straightening roller 1624 in the front straightening component 162 is used as the front guard positioning function of the border buffer, its stopping position needs to correspond to the corner code paper cutting position. In addition, in the flipping module 23, the straightening clamping component 236 on the flipping plate 234 near the corner code paper cutting component 244, the working stopping position of its straightening clamp 2362 needs to correspond to the corner code paper cutting position.

[0071] In order to cover the flipping of various different border group widths, the length design of the border clamp 235 in the flipping module 23 will take into account the current common border widths, and try to cover the border group width formed after caching a certain number of different width specifications of borders.

[0072] Based on the above, in practical applications, due to changes in frame specifications, the following situation may occur: the flipping center of the flipping plate 234, i.e., the rotation center of the fourth drive component 233, is fixed, while the frame group cached on the cache conveyor line 12 is positioned by a single-sided reference (i.e., the position where the second alignment roller 1624 in the front alignment component 162 stops when used as the front stop positioning function of the frame cache). When the overall width of the frame group cached on the cache conveyor line 12 changes, the center of the frame group will deviate from the flipping center of the flipping plate 234. If the next set of forward frame groups entering the cache conveyor line 12 is still positioned by the front stop of the previous set of frame groups, the previous set of forward frame groups, after being flipped and converted into a reverse frame group, cannot be matched with the current set of forward frame groups one-to-one. This will result in some frames in the reverse frame group not having a corresponding forward frame below, or some frames in the forward frame group not having a corresponding reverse frame above, thus causing the forward and reverse matching to fail.

[0073] To address the aforementioned technical problems, this embodiment includes a first cylinder 1611 in the rear alignment component 161 and a first drive component 1621 in the front alignment component 162. Specifically, the workflow of the second alignment module 16 in solving the above technical problems is as follows: Figure 7-8 As shown, under the initial conditions: the rotation center position of the flipping module 23 is known, and the cutting position of the corner code paper end is also known. The distance between the rotation center of the flipping module 23 and the cutting position of the corner code paper end is set to L1. The overall width of the frame group buffered on the buffer conveyor line 12 is known to be L1+L2. The second alignment module 16 and the flipping module 23 include the following steps in solving the above technical problems:

[0074] S1. The first driving component 1621 drives the second alignment roller 1624 from the initial position to the adjustment position. The initial position corresponds to the cutting position at the end of the corner code divider. The adjustment position is the position where the second alignment roller 1624 is L2 away from the rotation center of the flipping module 23. If L2 is greater than L1, the second alignment roller 1624 moves from the initial position a distance of L2-L1 away from the rotation center of the flipping module 23, and then reaches the adjustment position. Figure 7 As shown; if L1 is greater than L2, the second alignment roller 1624 moves from its initial position toward the rotation center of the flipping module 23 by a distance of L1-L2, and then reaches the adjusted position, as shown. Figure 8 As shown;

[0075] S2. The borders enter the buffer conveyor line 12 one by one and abut against the second straightening roller 1624 at the B end. When the buffer reaches the set number, the first positive border group is obtained. At this time, the distance from the B end of the first positive border group to the rotation center of the flip module 23 is L2, and the distance from the A end of the first positive border group to the rotation center of the flip module 23 is L1.

[0076] S3. The frame clamping plate 235 in the flipping module 23 lifts the first positive frame group from the bottom of both ends AB and raises the first positive frame group to a high position. At the same time, the two straightening clamping plates 2362 hold the AB ends of the first positive frame group. Then the flipping plate 234 flips 180° to flip the first positive frame group 180° to obtain the reverse frame group. At this time, the distance from the A end of the reverse frame group to the rotation center of the flipping module 23 is L1, that is, the A end of the reverse frame group is located in the initial position, and the distance from the A end of the reverse frame group to the rotation center of the flipping module 23 is L2.

[0077] S4. The first driving component 1621 drives the second aligning roller 1624 back to the initial position;

[0078] S5. The borders enter the buffer conveyor line 12 one by one and abut against the second straightening roller 1624 at the B end. When the buffer reaches the set number, the second positive border group is obtained.

[0079] S6. The first cylinder 1611 drives the first alignment roller 1614 to align the position of end A of the second positive frame group. At this time, the distance from end B of the second positive frame group to the rotation center of the flip module 23 is L1, that is, end B of the second positive frame group is located in the initial position, and the distance from end A of the second positive frame group to the rotation center of the flip module 23 is L2. Therefore, the second positive frame group and the upper reverse frame group are in a state of precise vertical correspondence.

[0080] S7. After the corner code spacer feeding and inserting module 24 inserts the corner code spacer into both ends of the second positive frame group, the flipping module 23 clamps the reverse frame group and descends to engage with the second positive frame group below, thus obtaining the positive and negative engaged frame group.

[0081] The corner code spacer feeding and inserting module 24 inserts corner code spacers at both ends of the second positive frame group, specifically including:

[0082] The corner code spacer feeding assembly 241 continuously supplies strip-shaped corner code spacers 300; the corner code spacer pulling assembly 242 clamps the head of the corner code spacer 300 from the corner code spacer feeding assembly 241 and pulls it out along the X direction for a set length; the corner code spacer clamping assembly 243 clamps the pulled-out corner code spacer 300; the corner code spacer cutting assembly 244 cuts the corner code spacer 300 at its tail end; the transfer assembly 245 drives the corner code spacer clamping assembly 243 to move, driving the corner code spacer 300 to pass under the flipping module 23 and place it at the designated positions at both ends A and B of the second positive frame group, completing the placement of the corner code spacer.

[0083] The above actions effectively solve the problem that the geometric center of the buffered border group on the buffer conveyor line 12 is inconsistent with the rotation center of the flip module 23, which causes the border to not be able to be accurately snapped together.

[0084] The second alignment module 16 aligns the positions of the two sides of the second positive frame group in the X direction. This ensures that the frames in the second positive frame group abut against each other and that the position of the second positive frame group is stable and does not wobble, thereby ensuring the reliability and effectiveness of the frame snapping process.

[0085] The palletizing and handling mechanism 3 can adopt the "palletizing and handling mechanism" in the prior art patent CN118527375B, so its structure will not be described in detail in this embodiment.

[0086] The release paper placement mechanism 4 can adopt the "strip placement unit" in patent CN118527375B or the "strip automatic feeding and placement mechanism" in patent CN223032409U in the prior art. Therefore, its structure will not be described in detail in this embodiment.

[0087] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this invention, and these all fall within the protection scope of this invention.
