Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of photovoltaic profile stacking equipment, in particular to a profile stacking equipment and method. BACKGROUND

[0002] The photovoltaic frame is an important component of the photovoltaic equipment. After the frame is manufactured, it is stacked together for transportation and handling. In order to facilitate subsequent frame assembly operation, corner fittings are installed at both ends of the frame. In order to save space, one of the frames is flipped and misaligned when stacking, and in order to prevent friction and scratches between the two frames, a layer of paper is placed between the two frames before they are flipped and buckled. This process is the stacking process of the frame.

[0003] In order to realize efficient automatic stacking of the frame, the prior art patent CN119873397A discloses an automatic stacking device for photovoltaic frames, which includes a conveying mechanism, a truss gripping mechanism and an upper corner paper mechanism. Through the cooperation of the feeding synchronous belt and the clamping frame, efficient conveying, flipping and stacking of the photovoltaic frame are realized, and continuous paper strips are ensured. However, the device has the following disadvantages: (1) The overall space occupation of the device is large, which is not conducive to the use of space-limited scenarios; (2) The device is provided with a stacking station and a feeding station, and the frame flipping and stacking are integrated together to form a truss gripping mechanism. The conveying mechanism conveys a row of frames to the feeding station, the truss gripping mechanism clamps them, then flips and buckles them onto a newly entered row of frames, completes the forward and reverse buckling, and then clamps the forward and reverse buckled frames together from the feeding station to the stacking station. After the stacking is completed and the truss gripping mechanism returns to the feeding station again, the next cycle of frame flipping and buckling and handling operation can be performed. The overall beat is slow, the efficiency is low, and it cannot meet the higher beat requirement of the stacking demand; (3) In the device, the flipping center of the flipping mechanism in the truss gripping mechanism is fixed, and the geometric center of the frame group conveyed to the feeding synchronous belt must be consistent with the flipping center. In this way, the frame group can be effectively buckled with the next row of frames after being flipped by 180°. However, if the overall width of the stacked frame changes, although the position of the blocking and correcting module on the feeding synchronous belt can be adjusted to keep the overall geometric center of the frame unchanged, the position of the corner paper needs to be adjusted, mainly the position of the tail end of the corner paper after being pulled out and cut. It is inconvenient and time-consuming to adjust.

[0022] The embodiment designs a new frame stacking mode, and the general process is as follows: the conveying mechanism 1 conveys the forward frames to the forward-reverse clamping and blocking work station; when the set number is reached, the overturning and blocking mechanism 2 clamps the whole row of forward frames and lifts them up and overturns them by 180° to obtain a group of reverse frames; the conveying mechanism 1 conveys the next group of forward frames to the forward-reverse clamping and blocking work station, in the process, the overturning and blocking mechanism 2 has prepared the corner code blocking paper, and places the corner code blocking paper to the specified positions at the two ends of the group of forward frames after the next group of forward frames is in place; the overturning and blocking mechanism 2 moves the group of reverse frames on it downwards and clamps and places them on the group of forward frames below to obtain a clamped frame group; the stacking and carrying mechanism 3 carries the clamped frame group from the forward-reverse clamping and blocking work station to the stacking work station for stacking; at the stacking work station, the blocking paper placing mechanism 4 completes the placement of the frame blocking paper according to requirements; in the stacking process, the conveying mechanism 1 and the overturning and blocking mechanism 2 have started the next round of frame conveying, forward-reverse frame clamping and corner code blocking paper insertion and other operations, and the above steps are repeated until the stacked frames reach the set height.

[0023] In the embodiment, the conveying mechanism 1 comprises a distribution conveying line 11 covering the feeding work station in conveying range, a buffer conveying line 12 covering the forward-reverse clamping and blocking work station in conveying range, a first position correcting module 13 arranged on the Y direction both sides of the distribution conveying line 11 and correcting the positions of the two ends of the frame in Y direction, a distribution module 14 for controlling the frames entering the distribution conveying line 11, a stopping module 15 for blocking the frames on the output side of the distribution conveying line 11, and a second position correcting module 16 for correcting the positions of the frames on the buffer conveying line 12 in X direction.

In the front alignment assembly 162, the first driving member 1621 is arranged to drive the second alignment roller 1624 to move along the X direction, which can be adapted to various different width specifications of the frame alignment.

[0028] In the present embodiment, the turnover paper jam mechanism 2 is the core mechanism of the device, which is used to realize the turnover of the frame, the feeding of the corner code paper, and the insertion of the corner code paper. It includes two sub-modules 20 arranged on both sides of the positive and negative buckling and jamming workstations Y. 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 turnover module 23 arranged on the bracket 22 and facing the positive and negative buckling and jamming workstations, and a corner code paper feeding and jamming module 24 arranged on the bracket 22 and located on one side of the turnover module 23 along the Y direction. The corner code paper feeding and jamming module 24 is located on both sides of the turnover module 23 along the Y direction of the positive and negative buckling and jamming workstations.

[0029] The support 22 has a support vertical surface (not labeled in the figure) facing the positive and reverse buckle paper feeding station, and the support vertical surface has a through window 221 through both Y-direction sides. In the embodiment, the support 22 includes a horizontal support base 222, a pair of support columns 223 arranged on the horizontal support base 222, and a connecting beam 224 connecting the top of the pair of support columns 223 together, and the space between the support columns 223 forms the through window 221, so that the corner code paper supply feeding plug module 24 can clamp the corner code paper 300 to move along the Y-direction through the through window 221 and then place the corner code paper 300 on the frame end of the buffer conveying line 12.

[0030] The turnover module 23 includes a third driving member 231 fixed on the support 22, a third support plate 232 driven by the third driving member 231 to move up and down on the support columns 223, a fourth driving member 233 fixed on the third support plate 232, a turnover plate 234 driven by the fourth driving member 233 to turn around the Y-axis, a frame clamping plate 235 fixed on the side surface of the turnover plate 234 facing the positive and reverse buckle paper feeding station and used for bearing the frame end, and a pair of position correction clamping assemblies 236 arranged on the turnover plate 234 and used for correcting the position of the frame group on the frame clamping plate 235 in the X-direction.

[0031] The turnover module 23 is movably arranged on the pair of support columns 223, when it is needed to clamp and turn the frame on the buffer conveying line 12, the third support plate 232 is lowered to a low position, the two frame clamping plates 235 are moved towards each other in the Y-direction to clamp the frame, and then the third support plate 232 is raised to a set height, and the fourth driving member 233 is driven to realize 180° turnover of the frame, and at the same time, the space below is avoided to enable the corner code paper supply feeding plug module 24 to perform the corner code paper feeding plug operation.

[0032] In order to adapt to the position correction clamping of frame groups of various different width specifications on the frame clamping plate 235, the position correction clamping assemblies 236 are adjustably arranged on the turnover plate 234 in the X-direction. Specifically, the turnover plate 234 is provided with a second sliding rail 237, and the position correction clamping assemblies 236 are slidingly arranged on the second sliding rail 237 and fixed after being adjusted to a position. The position correction clamping assemblies 236 include a fourth cylinder 2361 and a position correction clamping plate 2362 driven by the fourth cylinder 2361 to move in the X-direction.

[0033] The corner code paper separator feeding plug module 24 comprises a corner code paper separator feeding assembly 241 arranged on the support 22, a corner code paper separator pulling assembly 242 for pulling out the corner code paper separator 300 in the corner code paper separator feeding assembly 241 by a set length along the X direction, a corner code paper separator clamping assembly 243 arranged along the corner code paper separator pulling-out section and used for clamping the corner code paper separator, a corner code paper separator cutting assembly 244 arranged close to the corner code paper separator feeding assembly 241 and used for cutting the corner code paper separator after the corner code paper separator is pulled out by the set length, and a transfer assembly 245 for driving the corner code paper separator clamping assembly 243 to move in space positions to realize the placement of the corner code paper separator.

[0034] The corner code paper separator feeding assembly 241 is a conventional roll feeding assembly structure.

[0035] The corner code paper separator pulling assembly 242 comprises a fifth driving member 2421 fixed on the support 22, a fourth support plate 2422 moved along the X direction driven by the fifth driving member 2421, and a first clamping jaw assembly 2423 fixed on the fourth support plate 2422. The fifth driving member 2421 drives the first clamping jaw assembly 2423 to clamp the end of the corner code paper separator and pull it out by a set length along the X direction, so as to realize the pulling.

[0036] The corner code paper separator clamping assembly 243 comprises a fifth support plate 2431 and a plurality of second clamping jaw assemblies 2432 arranged along the X direction and arranged on the fifth support plate 2431 in a spaced manner. The second clamping jaw assemblies 2432 are arranged along the corner code paper separator pulling-out direction and jointly clamp the corner code paper separator 300.

[0037] The corner code paper separator cutting assembly 244 comprises a fifth cylinder 2441 and a pneumatic shear 2442 moved along the Y direction driven by the fifth cylinder 2441. The fifth cylinder 2441 drives the pneumatic shear 2442 to move along the Y direction, so as to realize the position switching between the waiting position and the working position. In the working position, the corner code paper separator 300 is cut off by the pneumatic shear 2442.

[0038] The transfer assembly 245 comprises a sixth cylinder 2451 fixed on the support 22, a sixth support plate 2452 moved up and down driven by the sixth cylinder 2451, and a seventh cylinder 2453 fixed on the sixth support plate 2452. The fifth support plate 2431 is slidably arranged on the sixth support plate 2452 along the Y direction and is moved along the Y direction driven by the seventh cylinder 2453. The up and down movement and the Y direction movement of the corner code paper separator clamping assembly 243 can be realized by the transfer assembly 245.

[0039] Due to the diversity of the stacking frame, the width of a single frame is various, and then the overall width of the frame group formed after the frame of different width specifications is cached to a set number is also different, for example, 1 meter, 1.1 meters or 1.2 meters, etc. However, in the embodiment, the position of the corner code paper cutting module 244 in the turnover paper jamming mechanism 2 is basically fixed, so the position of one end of the corner code paper is basically fixed, but the length of the corner code paper pulled out can be automatically adjusted according to the width of the front frame on the front and rear buckling paper jamming station. Therefore, in the embodiment, the position of the second normalizing roller 1624 in the front normalizing assembly 162 needs to correspond to the position of the corner code paper cutting when it is used as a frame caching front stop positioning function, and the normalizing clamping assembly 236 on the turnover plate 234 in the turnover module 23 needs to correspond to the position of the corner code paper cutting when it is used as a frame caching front stop positioning function.

[0040] In order to cover the turnover of various frame group widths, the length of the frame clamping plate 235 in the turnover module 23 is designed to consider the current several common width frames, and try to cover the frame group width formed after a certain number of frames of different width specifications are cached.

[0041] Based on the above situation, in actual application, due to the change of frame specifications, there may be such a situation: the turnover center of the turnover plate 234, i.e. the rotation center of the fourth driving member 233, is fixed, and the frame group cached on the caching conveying line 12 is positioned by single side reference (i.e. the position of the second normalizing roller 1624 in the front normalizing assembly 162 when it is used as a frame caching front stop positioning function), when the overall width of the frame group cached on the caching conveying line 12 changes, the center of the frame group will deviate from the turnover center of the turnover plate 234; if the next group of front frames entering the caching conveying line 12 is still positioned by the front frame of the previous group, then after the previous group of front frames is converted into a reverse frame group by turnover, it cannot be corresponded one by one with the current group of front frames, and there will be a part of the reverse frame group without corresponding front frame below, or a part of the front frame group without corresponding reverse frame above, which will lead to the failure of front and rear buckling.

[0042] In order to solve the above technical problem, in the embodiment, a first cylinder 1611 is arranged in the rear normalizing assembly 161, and a first driving member 1621 is arranged in the front normalizing assembly 162. Specifically, the working process of the second normalizing module 16 to solve the above technical problem is as follows: Figures 7-8As shown, under the initial condition: the rotation center position of the turnover module 23 is known, and the cutting position of the paper end of the corner code is also known. The distance between the rotation center of the turnover module 23 and the cutting position of the paper end of the corner code is set as L1, and the overall width of the frame group cached on the cache conveying line 12 is L1+L2. The second alignment module 16 and the turnover module 23 include the following steps when solving the above technical problems: S1, the first driving member 1621 drives the second alignment roller 1624 to move from the initial position to the adjustment position. The initial position corresponds to the cutting position of the paper end of the corner code, and the adjustment position is the position of the second alignment roller 1624 at a distance of L2 from the rotation center of the turnover module 23. If L2 is greater than L1, the second alignment roller 1624 moves from the initial position to the adjustment position by a distance of L2-L1 away from the rotation center of the turnover module 23, as shown in Figure 7 If L1 is greater than L2, the second alignment roller 1624 moves from the initial position to the adjustment position by a distance of L1-L2 towards the rotation center of the turnover module 23, as shown in Figure 8 ; S2, the frames enter the cache conveying line 12 one by one and abut against the second alignment roller 1624 at the B end. When cached to a set number, the first forward frame group is obtained. At this time, the B end of the first forward frame group is at a distance of L2 from the rotation center of the turnover module 23, and the A end is at a distance of L1 from the rotation center of the turnover module 23. S3, the frame clamping plate 235 in the turnover module 23 lifts the first forward frame group from the bottom of the AB two ends, and lifts the first forward frame group to a high position. At the same time, the two alignment clamping plates 2362 clamp the AB two ends of the first forward frame group, and then the turnover plate 234 is turned over by 180° to obtain the reverse frame group. At this time, the A end of the reverse frame group is at a distance of L1 from the rotation center of the turnover module 23, i.e. the A end of the reverse frame group is located at the initial position, and the A end of the reverse frame group is at a distance of L2 from the rotation center of the turnover module 23. S4, the first driving member 1621 drives the second alignment roller 1624 to return to the initial position. S5, the frames enter the cache conveying line 12 one by one and abut against the second alignment roller 1624 at the B end. When cached to a set number, the second forward frame group is obtained. S6, the first cylinder 1611 drives the first alignment roller 1614 to position the A end of the second forward frame group. At this time, the B end of the second forward frame group is at a distance of L1 from the rotation center of the turnover module 23, i.e. the B end of the second forward frame group is located at the initial position, and the A end of the second forward frame group is at a distance of L2 from the rotation center of the turnover module 23. Therefore, the second forward frame group and the reverse frame group above are in a state of accurate position correspondence. S7, after the corner code paper supply and feeding module 24 is inserted into the corner code paper at both ends of the second forward frame group, the turnover module 23 clamps the reverse frame group and descends to be buckled with the second forward frame group below to obtain the forward and reverse buckled frame group.

[0043] The corner code paper supply and feeding module 24 inserting the corner code paper at both ends of the second forward frame group specifically includes: The corner code paper supply assembly 241 continuously supplies the strip-shaped corner code paper 300; the corner code paper pulling assembly 242 pulls out the head of the corner code paper 300 from the corner code paper supply assembly 241 in the X direction to a set length; the corner code paper clamping assembly 243 clamps the pulled-out corner code paper 300; the corner code paper cutting assembly 244 cuts the corner code paper 300 at the tail end; the transfer assembly 245 drives the corner code paper clamping assembly 243 to move, drives the corner code paper 300 to pass through below the turnover module 23 and then places it at the designated positions at both ends A and B of the second forward frame group, completing the placement of the corner code paper.

[0044] Through the above actions, the problem that the geometric center of the frame group cached on the cache conveying line 12 is inconsistent with the rotation center of the turnover module 23, causing the frame to be unable to be accurately buckled up and down, is effectively solved.

[0045] The second normalizing module 16 normalizes the positions of the two sides of the second forward frame group in the X direction, which can make the frames in the second forward frame group abut against each other and ensure the stability of the position of the second forward frame group, thereby ensuring the reliability and effectiveness of the forward and reverse buckling process of the frame.

[0046] The stacking and carrying mechanism 3 can adopt the "stacking and carrying mechanism" in the prior art patent CN118527375B, so the structure thereof will not be described again in this embodiment.

[0047] The isolation paper placing mechanism 4 can adopt the "strip placing unit" in the prior art patent CN118527375B or the "automatic strip feeding and placing mechanism" in the prior art patent CN223032409U, so the structure thereof will not be described again in this embodiment.

[0048] For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the protection scope of the present application.
