Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module production equipment, and particularly to a photovoltaic module end strip cutting and laying machine. Background Art

[0002] EVA (ethylene vinyl acetate) is a key structural material commonly used in solar photovoltaic modules. It is used between the back of solar cells and the glass top cloth, playing roles of fixation, insulation, and protection. EVA is widely used in various photovoltaic modules, including polycrystalline silicon solar cell modules, monocrystalline silicon solar cell modules, amorphous silicon solar cell modules, etc. It can effectively protect the cells and circuit systems, improving the light energy conversion efficiency and the lifespan of the module.

[0003] Before lamination, the component glass of the photovoltaic battery pack needs to be first laid with end strips and cells, then end strips and a backplane are laid again, and finally it enters a laminator for lamination. Currently, in the process of cutting and laying end strips, it has gradually evolved from manual single-machine operation to fully automatic machine operation. For example, in the prior art (CN117342328A, CN117712211B, CN117507053A), related technical solutions for punching a让位孔 (letting-through hole) for the bus bar to pass through, cutting, and laying of large EVA coils are disclosed. In the equipment disclosed in the above patent documents, a horizontal unwinding mechanism is used for loading the large EVA coil. On the one hand, the unwinding mechanism in the above equipment needs to occupy the dimension in the length direction of the machine frame, making the equipment large in volume and large in floor area. On the other hand, such unwinding mechanisms can only complete the laying of cushion strips on one set of opposite sides (short sides or long sides) of the photovoltaic module. For the cushion strips in the photovoltaic module in the shape of Figure 13 shown as a日字 (Chinese character 'day' shape), that is, including three short cushion strips corresponding to the short sides of the photovoltaic module arranged in parallel at intervals and two long cushion strips corresponding to the long sides of the photovoltaic module arranged in parallel at intervals. The two long cushion strips and the three short cushion strips form a 'day' character. And in addition to the difference in length between the long cushion strips and the short cushion strips, the short cushion strips need to be punched with letting-through holes for the bus bar to pass through. Therefore, the laying of the long cushion strips and the short cushion strips cannot be shared, and the above disclosed prior art cannot simultaneously complete the laying of the cushion strips on two sets of opposite sides, that is, the laying of the end strips in the 'day' shape. And to achieve the laying of the end strips in the 'day' shape, the equipment volume will increase, the floor area will be large, and the equipment structure will be complex and costly. How to improve the structure of the loading mechanism and layout the loading mechanism so that the volume and floor area of the overall equipment will not increase significantly and at the same time can achieve the cutting and laying of the end strips in the 'day' shape is a technical problem to be solved. To solve the above technical problems, it is necessary to provide a new photovoltaic module end strip cutting machine to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0018] In order to make the object, technical scheme and advantages of the present application more clear and obvious, the present application is further described in detail below with specific embodiments and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. In addition, in the following description, the description of the known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.

[0019] This invention provides a photovoltaic module end strip cutting and laying machine, wherein the end strips (material can be EVA or POE) are in a H-shape, see [reference]. Figure 13 It includes two parallel spaced long pads 310 and three parallel spaced short pads. The two ends of one short pad at any end are connected to the inner sides of the corresponding ends of the two long pads 310, and the two ends of the middle short pad are connected to the inner sides of the middle sections of the two long pads 310. The three short pads are punched with a plurality of clearance holes 330 along their length direction (only the middle short pad has clearance holes 330 shown in the figure), while the long pads 310 do not have clearance holes 330.

[0020] See Figures 1 to 12 The cutting and laying machine of this invention includes a frame 100, a conveying mechanism 200, two feeding mechanisms 11, two shearing mechanisms 12, two pulling mechanisms 13, two temporary storage units 14, two handling units 15, and a punching mechanism. The frame 100 includes an internally hollow cuboid frame and an external outer shell plate (not shown). For ease of description, in this embodiment of the invention, the front-to-back direction of the frame 100 is described as the first direction, the left-to-right direction as the second direction, and the up-down direction as the third direction. That is, the first and second directions are perpendicular in the horizontal plane, and the first, second, and third directions are perpendicular to each other in space. The conveying mechanism 200 passes through a set of opposite sides of the frame 100 from the bottom along the first direction. Figure 1The front and rear sides shown are used to convey the photovoltaic module to be laid with the herringbone end strip 300 into the rack 100 and fix it, so as to facilitate the subsequent laying of the herringbone end strip 300. The conveying mechanism 200 is a conventional mechanism for photovoltaic module transportation in the prior art, and the specific structure will not be described in detail, which is the prior art and not the point of the present application, and is easily known by those skilled in the art. When the photovoltaic module is transported to the position to be laid, the long side of the photovoltaic module is parallel to the second direction, and the short side is parallel to the first direction. One of the feeding mechanisms 11 is used to perform the feeding of the strip corresponding to the three short pad strips of the herringbone end strip 300, and the punching mechanism, the pulling mechanism 13, the cutting mechanism 12, the temporary storage unit 14 and the carrying unit 15 corresponding thereto are used to perform the positioning hole 330, the stretching, the cutting, the temporary storage and the carrying and laying, respectively. The other feeding mechanism 11 is used to perform the feeding of the strip corresponding to the two long pad strips 310 of the herringbone end strip 300, and the pulling mechanism 13, the cutting mechanism 12, the temporary storage unit 14 and the carrying unit 15 corresponding thereto are used to perform the stretching, the cutting, the temporary storage and the carrying and laying, respectively. Exemplarily, the feeding mechanism 11 for feeding the strip of the short pad strip is arranged at the front side of the right end of the rack 100, and the feeding mechanism 11 for feeding the strip of the long pad strip 310 is arranged at the rear side of the right end of the rack 100, that is, the two feeding mechanisms 11 are on the same side. As an alternative embodiment, the feeding mechanism 11 for feeding the strip of the short pad strip is arranged at the front side of the right end of the rack 100, and the feeding mechanism 11 for feeding the strip of the long pad strip 310 is arranged at the front side of the left end of the rack 100, that is, the two feeding mechanisms 11 are on different sides, that is, on the two sides of the conveying mechanism 200 and opposite to each other. As another alternative embodiment, the feeding mechanism 11 for feeding the strip of the short pad strip is arranged at the front side of the right end of the rack 100, and the feeding mechanism 11 for feeding the strip of the long pad strip 310 is arranged at the rear side of the left end of the rack 100, that is, the two feeding mechanisms 11 are on different sides and diagonally arranged. Regardless of the above several embodiments, the feeding mechanism 11 is arranged at the bottom, and the cutting mechanism 12, the pulling mechanism 13, the temporary storage unit 14 and the carrying unit 15 corresponding thereto are arranged at the upper end of the rack 100. The difference is that the directions in which the cutting mechanism 12, the pulling mechanism 13, the temporary storage unit 14 and the carrying unit 15 work are different, and the feeding mechanism 11 for the short pad strip and the cutting mechanism 12 behind it or above the temporary storage unit 14 corresponding thereto (the carrying unit 15 corresponding thereto needs to be avoided to avoid interference) is also provided with a punching mechanism for positioning the hole 330 of the strip. Specifically, the pulling mechanism 13 for the short pad strip is used to stretch the strip in the first direction, and the temporary storage unit 14 for the short pad strip is also extended in the first direction. While the pulling mechanism 13 for the long pad strip 310 is used to stretch the strip in the second direction, and the temporary storage unit 14 for the long pad strip 310 is also extended in the second direction. That is, they are perpendicular and correspond to the length direction of the corresponding pad strip.In addition, the pulling length of the pulling mechanism 13 is different when pulling the material strip, because the length of the long cushion strip 310 and the short cushion strip is different. The carrying unit 15 for the long cushion strip 310 can at least move along the second direction and the third direction, and is preferably also movable along the first direction, and the carrying unit 15 for the short cushion strip can at least move along the first direction and the third direction, and is preferably also movable along the second direction, that is, in order to avoid interference, the carrying unit 15 for the long cushion strip 310 can be arranged on the cross beam of the rack 100, and the carrying unit 15 for the short cushion strip can be arranged on the longitudinal beam of the rack 100. The cutting and laying machine of the embodiment of the present application can fully utilize the bottom space of the rack 100, without increasing the size of the rack 100. The laying operation of the end strip of the long side and the short side of the photovoltaic module is realized by two independent mechanisms, and the feeding mechanism 11 adopts a multi-material disc mechanism rotating around the third direction, that is, the vertical axis, compared with the prior art in which the large material roll 110 rotates around the axis parallel to the length direction of the short cushion strip, and only the laying of the short side cushion strip can be realized. The cutting machine of the embodiment of the present application can simultaneously realize the laying operation of the long side and the short side cushion strip, while not significantly increasing the size and area occupied by the entire device.

[0021] As an alternative embodiment, the feeding mechanism 11 of the embodiment of the present application can also be other number, such as three or four. For example, when there are four, that is, there are two feeding mechanisms 11 for feeding the material strip of the long cushion strip 310 and the short cushion strip, respectively arranged at the four corner positions of the inner bottom of the rack 100. When there are three, one feeding mechanism 11 can be for feeding the material strip of the long cushion strip 310 or the short cushion strip, and the other two feeding mechanisms 11 can be for feeding the material strip of the short cushion strip or the long cushion strip 310, respectively arranged at three of the four corner positions of the inner bottom of the rack 100.

[0022] Because the structures of the feeding mechanism 11, the cutting mechanism 12, the pulling mechanism 13, the temporary storage unit 14 and the carrying unit 15 corresponding to the long cushion strip 310 and the short cushion strip of the embodiment of the present application are the same, only the arrangement position on the rack 100 is different, which is described above. Therefore, only one of them is described.

[0023] The width of the material strip of the material roll 110 in the embodiment of the present application is consistent with the width of the long cushion strip 310 or the short cushion strip of the day-shaped end strip 300. Therefore, only the material strip with the length consistent with the length of the long cushion strip 310 or the short cushion strip needs to be cut by the cutting mechanism 12 in the subsequent process.

[0024] As shown in Figure 2 , the feeding mechanism 11 of the embodiment of the present application all adopts multi-material disc feeding. Specifically, as shown in Figures 4 to 7As shown, the feeding mechanism 11 includes a material cart 111, a fixed shaft 117, a tray 115, a first auxiliary wheel frame 118, a second auxiliary wheel frame 119, a feeding drive component, and a locking assembly 114. The material cart 111 is slidably disposed in the bottom space of the frame 100 (for example, the feeding mechanism 11 of the long pad strip 310 is disposed on the front right side of the bottom of the frame 100, in which case the material cart 111 can move along the bottom space of the frame 100). Figure 1 The material can slide left and right as shown and be pulled out to the right. The feeding mechanism 11 corresponding to the short pad is located at the rear right end of the bottom of the frame 100. At this time, the material cart 111 can slide along the left and right direction as shown. Figure 1 (As shown, it slides forward and backward and is pulled out backward), that is, the material cart 111 can be pulled out from the right side panel or the rear side panel of the frame 100 and pushed into the frame 100 to facilitate the replacement of a new material roll 110. In order to realize the mobility of the material cart 111, in this embodiment of the invention, as shown... Figures 4 to 6 As shown, a linear guide rail 112 extending in a second direction (taking the feeding mechanism 11 corresponding to the long pad 310 as an example; if it were the feeding mechanism 11 corresponding to the short pad, then this would be the first direction) is provided at the bottom of the material cart 111. It should be noted that the linear guide rail 112 is preferably set on the ground, but it can also be set on the bottom panel of the frame 100 as an alternative. A slider 113 is also slidably mounted on the linear guide rail 112, and the slider 113 is fixed to the bottom of the material cart 111. In addition, a caster wheel 1110 is also provided at the bottom of the material cart 111 to make the pulling out and pushing of the material cart 111 smoother. Since the material roll 110 on the material cart 111 may move when it is driven to rotate for feeding, thus affecting the feeding, in this embodiment of the invention, a locking component 114 is provided on the inner side of the ground of the material cart 111 within the frame 100 or on the bottom surface of the frame 100 for locking and fixing the material cart 111 after it is pushed into place. A locking component 114 is provided at the middle position of the material cart 111 along a third direction, i.e. Figure 4 The vertically extending fixed shaft 117 shown is fitted with a tray 115 and a roll 110, which are fixed to the fixed shaft 117. For example, as shown... Figure 7As shown, the fixed shaft 117 includes a shaft body with an axis along the third direction, and at least one expansion sleeve 1171 is arranged along the axis direction of the shaft body and can be radially expanded or contracted to achieve expansion or contraction. If the embodiment of the present application is the feeding mechanism 11 corresponding to the long pad strip 310, at least two expansion sleeves 1171 are preferred, which can feed two material rolls 110 at a time, corresponding to the two long pad strips 310 of the herringbone end strip 300. If the embodiment of the present application is the feeding mechanism 11 corresponding to the short pad strip, at least three expansion sleeves 1171 are preferred, which can feed three material rolls 110 at a time, corresponding to the three short pad strips of the herringbone end strip 300. The diameter of the expansion sleeve 1171 is larger than the diameter of other positions of the shaft body. The expansion sleeve 1171 can be driven to expand by pneumatic or electric means. One end of the fixed shaft 217, i.e. the upper end as shown, is provided with a tightening driving member 1170. The axial ends of the expansion sleeve 1171 are used to fix the trays 115. The material roll 110 is clamped on the expansion sleeve 1171, and the tray 115 is fixed at the axial upper and lower ends of the expansion sleeve 1171. In the embodiment of the present application, one feeding driving member contacts two trays 115 at the axial ends of one expansion sleeve 1171. Figure 4 When feeding, the feeding driving member drives the rotation of the tray 115 to drive the rotation of the material roll 110 fixed on the expansion sleeve 1171 and located between the two driven trays 115. That is, the feeding driving member is arranged outside the tray 115 and in contact with the tray 115, and drives the rotation of the tray 115 around the axis of the fixed shaft 117 through friction, thereby driving the rotation of the material roll 110 for feeding. Preferably, one feeding driving member can also be in contact with the rotation of two adjacent trays 115 between any two adjacent expansion sleeves 1171. That is, one feeding driving member can simultaneously drive the feeding of two material rolls 110, greatly improving the efficiency. When the number of feeding driving members is at least two, at least two feeding driving members are arranged vertically upward and downward (which can be on the same vertical line; which can be arranged upward and downward in a circumferential direction, that is, not on the same vertical line; which can be arranged in a circumferential direction, that is, two feeding driving members are on the same horizontal plane and drive the same tray 115). For the feeding driving member, the feeding driving member in the embodiment of the present application can approach or move away from the tray 115 in the radial direction of the tray 115. Only when the corresponding tray 115 needs to be driven to rotate, the feeding driving member approaches the tray 115 and contacts the tray 115. When the corresponding tray 115 does not need to be driven to rotate, the feeding driving member moves away from the corresponding tray 115 and does not contact the corresponding tray 115. That is, multiple feeding driving members are in contact with and drive the rotation of their corresponding trays 115, that is, when one feeding driving member is in contact with and drives the rotation of its corresponding tray 115, the other feeding driving members move away from their corresponding trays 115. For example, Figures 4 to 6As shown, the feeding drive includes a feeding drive wheel 116 whose axis extends along a third direction, a feeding drive motor that drives the feeding drive wheel 116 to rotate, and a displacement drive component 1160, such as a telescopic cylinder and / or a linear slide block, that drives the feeding drive motor and the feeding drive wheel 116 as a whole to move closer to or further away from the corresponding pallet 115 along the radial direction of the pallet 115. In this embodiment of the invention, a first auxiliary wheel frame 118 and a second auxiliary wheel frame 119 are respectively provided on two adjacent sides of the material cart 111 on the outer side of the pallet 115. The first auxiliary wheel frame 118 is provided with a first auxiliary wheel 1181, which extends along a third direction, i.e., as shown in the figure. Figure 4 or Figure 6 Multiple auxiliary wheels are provided in the vertical direction as shown. It should be noted that the number and height of the first auxiliary wheels 1181 correspond to the material roll 110 being fed. The axis of the first auxiliary wheels 1181 is along a third direction, meaning the material strip is fed vertically from the material roll 110 (the wider side of the material strip is along the vertical direction). The second auxiliary wheel frame 119 is equipped with second auxiliary wheels 1191. Similarly, the second auxiliary wheels 1191 are along a third direction, i.e., as shown... Figure 4 or Figure 6 Multiple auxiliary wheels 1191 are arranged vertically, and their number and height correspond to the first auxiliary wheel 1181. In this embodiment of the invention, the axis of the second auxiliary wheel 1191 is along the horizontal direction, that is, along the second direction (here, the feeding mechanism 11 with a long pad 310 is used as an example; if it is a feeding mechanism 11 with a short pad, it is the first direction). After passing the second auxiliary wheel 1191, the material strip changes from a vertical state to a horizontal state. Then, the material strip changes back to a vertical state (the long side of the material strip is along the vertical direction) and reaches the shearing mechanism 12 upwards. Since the material roll 110 on the material cart 111 may move the material cart 111 when it is driven to rotate for feeding, thus affecting the feeding, such as... Figure 5 As shown, in this embodiment of the invention, a locking assembly 114 is provided at one end of the material cart 111 along the extending direction of the linear guide rail 112 and on the bottom surface or ground of the frame 100 to lock the material cart 111 in place and prevent it from moving. For the locking assembly 114, as... Figure 5As shown, the locking mechanism 114 includes a locking plate 1141 and a locking cylinder 1142. The locking plate 1141 is arranged at the bottom of one end of the trolley 111 along the extending direction of the linear guide rail 112, i.e. the side close to the conveying mechanism 200. The locking cylinder 1142 is arranged on the rack 100 or the ground and can be extended and retracted. The locking plate 1141 is provided with a locking hole, the axis of which is perpendicular to the extending direction of the linear guide rail 112. The locking cylinder 1142 is provided with a locking rod connected to the piston or piston rod thereof, which can extend towards the locking hole or retract from the locking hole. The axis of the locking rod is parallel to the locking hole. After the trolley 111 is pushed to the predetermined position, the locking rod can be extended and inserted into the locking hole to lock the trolley 111. Alternatively, the number of the material rolls 110 in the embodiment of the present application can be only one. Although the efficiency is relatively low, the space occupied by the feeding mechanism 11 is smaller and the cost is lower. Alternatively, the axis of the fixed shaft 117 can be horizontal, such as along the first direction. Alternatively, the bottom of the trolley 111 can not be provided with the sliding block 113 and the linear guide rail 112.

[0025] As shown in Figure 8 and Figure 9 The cutting mechanism 12 includes a first frame 121, a material belt guiding assembly 122, a guide wheel assembly 123, a pressing member 125 and a pneumatic cutter 124. The first frame 121 is mounted on the rack 100 and above the feeding mechanism 11, such as Figure 1The right end front side of the frame 100 (for the same reason, as above, here is an example of the cutting mechanism 12 of the long mat strip 310 and is arranged at the right end front side of the frame 100, if it is the cutting mechanism 12 of the short mat strip and is arranged at the right end rear side of the frame 100, here should be the right end rear side of the frame 100). The tape guide assembly 122 is arranged at the lower part of the first frame body 121 and includes at least two groups of guide pieces arranged in the third direction, each group of guide pieces defines a guide cavity for the tape to be conveyed from bottom to top along the third direction, the size of the guide cavity is adjustable and consistent with the width of the tape during guiding to avoid lateral deviation of the tape. In order to realize the adjustment of the guide cavity, each group of guide pieces is composed of two guide blocks arranged opposite and spaced apart in the first direction (here is an example of the cutting mechanism 12 of the long mat strip 310, if it is the cutting mechanism 12 of the short mat strip, here should be the second direction). The guide blocks can be connected to the air cylinder (not shown) and driven to move laterally by the air cylinder to realize the adjustment of the guide cavity. The pulley assembly 123 is arranged above the tape guide assembly 122 and is used to pull and flatten the tape, so that the tape is converted from the vertical state to the horizontal state again, that is, the tape is converted from the long side along the third direction to the long side along the second direction (for the same reason, as above, here is an example of the cutting mechanism 12 of the long mat strip 310, if it is the cutting mechanism 12 of the short mat strip, here should be the first direction), so as to be consistent with the direction of the long mat strip 310 or the short mat strip of the I-shaped end strip 300 on the photovoltaic module to be laid. Specifically, the pulley assembly 123 includes a driving pulley 1231 and a driven pulley 1232 arranged opposite and movably above and below along the third direction, wherein the driving pulley 1231 is arranged below and fixed relative to the first frame body 121, the axis of the driving pulley 1231 is along the first direction and can rotate around the axis of the first direction (for the same reason, as above, here is an example of the cutting mechanism 12 of the long mat strip 310, if it is the cutting mechanism 12 of the short mat strip, here should be the second direction), the driven pulley 1232 is arranged above and can move up and down relative to the first frame body 121, that is, close to or away from the driving pulley 1231, for the same reason, the axis of the driven pulley 1232 is also along the first direction (for the same reason, as above, here is an example of the cutting mechanism 12 of the long mat strip 310, if it is the cutting mechanism 12 of the short mat strip, here should be the second direction) and can rotate around the axis of the first direction (for the same reason, as above, here is an example of the cutting mechanism 12 of the long mat strip 310, if it is the cutting mechanism 12 of the short mat strip, here should be the second direction). The driving pulley 1231 is connected with a speed reducer (not shown). The driving pulley 1231 and the driven pulley 1232 can be penetrated by the tape when they are away from each other, and can be compressed after the tape is penetrated, and the relative rotation of the two drives the tape to be conveyed towards the direction of the pneumatic scissors 124 behind.In order to facilitate the cutting of the material strip into a material strip, both sides of the cutting position of the material strip need to be fixed, and one end of the material strip is fixed by the material pulling mechanism 13, and the other end, i.e. the position between the guide roller assembly 123 and the pneumatic scissors 124, also needs to be fixed, which is achieved by providing a material pressing piece 125 in the present application. As shown in the drawings. Figure 2 The material pressing piece 125 is arranged along the second direction (for the same reason, as above, here it is taken as an example of the cutting mechanism 12 of the long cushion strip 310, if it is the cutting mechanism 12 of the short cushion strip, here it should be the first direction) that is, as shown in the drawings, from right to left (for the same reason, as above, here it is taken as an example of the cutting mechanism 12 of the long cushion strip 310 and arranged at the front side of the right end of the rack 100, if it is the cutting mechanism 12 of the short cushion strip and arranged at the rear side of the right end of the rack 100, here it should be from back to front). Figure 1 As shown in the drawings, the material pressing piece 125 is arranged at the rear of the guide roller assembly 123 along the second direction (for the same reason, as above, here it is taken as an example of the cutting mechanism 12 of the long cushion strip 310 and arranged at the front side of the right end of the rack 100, if it is the cutting mechanism 12 of the short cushion strip and arranged at the rear side of the right end of the rack 100, here it should be from back to front). Figure 1 As shown in the drawings, the material pressing piece 125 is arranged at the rear of the guide roller assembly 123 along the second direction (for the same reason, as above, here it is taken as an example of the cutting mechanism 12 of the long cushion strip 310 and arranged at the front side of the right end of the rack 100, if it is the cutting mechanism 12 of the short cushion strip and arranged at the rear side of the right end of the rack 100, here it should be from back to front). Figure 9 As shown in the drawings, the material pressing piece 125 is arranged at the rear of the guide roller assembly 123 along the second direction (for the same reason, as above, here it is taken as an example of the cutting mechanism 12 of the long cushion strip 310 and arranged at the front side of the right end of the rack 100, if it is the cutting mechanism 12 of the short cushion strip and arranged at the rear side of the right end of the rack 100, here it should be from back to front).

[0026] Preferably, in order to enable the operator to discover whether the material roll 110 has been released in time and to replenish the material in time, as shown in the drawings. Figure 8 and Figure 9As shown, in this embodiment of the invention, a tape detection sensor 126 for detecting the presence or absence of tape is also provided at the bottom of the first frame 121. When the tape is continuously fed, the tape detection sensor 126 at the bottom of the first frame 121 can detect the tape. However, when the current roll 110 is released and the tail end of the tape has passed the bottom of the first frame 121 and reached the tape guide assembly 122 at the lower end of the first frame 121, the tape detection sensor 126 will not detect the tape. Preferably, the cutting and laying machine is also provided with an alarm device (not shown). The tape detection sensor 126 is electrically connected to the alarm device. When the tape detection sensor 126 detects no tape, the alarm device will sound an alarm and stop the continued feeding of the tape. At this time, the operator can replace the new roll 110 in time. The tape detection sensor 126 is a conventional photoelectric sensor. The specific structure and principle are not described or limited, and are easily understood by those skilled in the art.

[0027] like Figure 10 As shown, the material pulling mechanism 13 includes a gripper 131 movable in a third direction to clamp or release, a gripper drive 132 (e.g., a cylinder) for driving the gripper 131 to perform clamping or releasing actions, and a material pulling drive (e.g., a structure composed of a guide rail, slider 113, motor, and transmission belt) for driving the gripper 131 to move in a second direction (similarly, as above, this is an example of a shearing mechanism 12 with a long pad 310; if it were a shearing mechanism 12 with a short pad, this would be the first direction). The gripper 131, gripper drive 132, and material pulling drive are all located at the upper end of the frame 100. It should be noted that in this embodiment of the invention, the speed of the gripper drive 132 of the material pulling mechanism 13 is lower than the speed of the reducer connected to the drive guide wheel 1231.

[0028] The temporary storage unit 14 is located below the material pulling drive component and is used for temporary storage of the material strips obtained after being cut by the shearing mechanism 12, which correspond to the length of the padding strips corresponding to the end strips. Specifically, as shown... Figure 11As shown, it comprises a carrier plate 141, a push rod 142 and a push driving element 143. Wherein the carrier plate 141 is plate-shaped and arranged on the rack 100 and extends along the second direction (for the same reason, as above, here is an example of the shearing mechanism 12 of the long mat strip 310, if it is the shearing mechanism 12 of the short mat strip, here it should be the first direction), the carrier plate 141 can be an integral plate, or can be spliced together by multiple small plates along the second direction (for the same reason, as above, here is an example of the shearing mechanism 12 of the long mat strip 310, if it is the shearing mechanism 12 of the short mat strip, here it should be the first direction). The width of the carrier plate 141 is greater than the width of at least two strips, so that at least two strips can be stored on the carrier plate 141. In order to reduce the distance of the carrying unit 15 moving along the first direction (for the same reason, as above, here is an example of the shearing mechanism 12 of the long mat strip 310, if it is the shearing mechanism 12 of the short mat strip, here it should be the second direction) to the strip on the temporary storage unit 14 away from the photovoltaic module side, the embodiment of the present application does so, and in the embodiment of the present application, the carrier plate 141 is provided with a plurality of regions along the first direction (for the same reason, as above, here is an example of the shearing mechanism 12 of the long mat strip 310, if it is the shearing mechanism 12 of the short mat strip, here it should be the second direction), such as the working area, standby area and recycling area, wherein the working area is close to the inner side and the standby area is located in the middle. The strip is initially placed in the standby area, and after the strip in the working area is fed by the carrying unit 15, the strip in the standby area needs to be moved to the working area. In order to realize the movement of the strip in the standby area to the working area, a plurality of grooves 1410 are provided on the carrier plate 141 along the second direction (for the same reason, as above, here is an example of the shearing mechanism 12 of the long mat strip 310, if it is the shearing mechanism 12 of the short mat strip, here it should be the first direction) and are spaced apart, the grooves 1410 extend along the first direction (for the same reason, as above, here is an example of the shearing mechanism 12 of the long mat strip 310, if it is the shearing mechanism 12 of the short mat strip, here it should be the second direction), a push rod 142 is arranged in the groove 1410, the push rod 142 can move up and down in the groove 1410 and can be driven by a push driving element 143 to move horizontally along the extension direction of the groove 1410. Wherein the up and down movement can be realized by means of a vertically telescopic jacking driving element 1431 such as a gas cylinder connected to the bottom of the push rod 142, and the horizontal movement along the extension direction of the groove 1410 can be realized by means of a push driving element 1432 such as a gas cylinder moving along the first direction (for the same reason, as above, here is an example of the shearing mechanism 12 of the long mat strip 310, if it is the shearing mechanism 12 of the short mat strip, here it should be the second direction). More specifically, the push rod 142 and the jacking driving element 1431 are arranged on a push frame 144 extending along the second direction (for the same reason, as above, here is an example of the shearing mechanism 12 of the long mat strip 310, if it is the shearing mechanism 12 of the short mat strip, here it should be the first direction), and the push frame 144 is connected with the driving end of the push driving element 1432.In operation, the pushing rod 142 is first driven upward by the lifting driving member 1431 to abut against the long side of the strip, and then the pushing frame 144 is driven by the pushing driving member 1432 to move horizontally along the first direction (for example, the shearing mechanism 12 of the long mat strip 310, if the shearing mechanism 12 of the short mat strip, the second direction is used) to drive the pushing rod 142 to push the strip along the extension direction of the groove 1410, so that the strip moves from one end of the groove 1410, i.e., the end away from the photovoltaic module, to the other end, i.e., the end close to the photovoltaic module. That is, the carrying unit 15 first sucks and lays the strip on the temporary storage unit 14 close to the photovoltaic module, and then the pushing driving member 143 pushes the strip originally on the temporary storage unit 14 away from the photovoltaic module to the side close to the photovoltaic module, so that the carrying unit 15 can suck, and the subsequent temporary storage of the new strip is facilitated.

[0029] Specifically, as shown in Figure 12 , the carrying unit 15 includes a three-axis moving module 151 connected to the upper end of the rack 100 and a suction cup 152 arranged on the three-axis moving module 151. The three-axis moving module 151 can move along the first direction, the second direction, and the third direction, so as to adjust the position of the suction cup 152 at the bottom in space. The three-axis moving module 151 is not described and limited, which is a conventional three-axis moving module 151 structure in the prior art and is easily known and implemented by those skilled in the art. For the suction cup 152, a conventional vacuum suction cup 152 in the prior art is used. When the three-axis moving module 151 moves downward along the third direction, the suction cup 152 can suck or lay, and when the three-axis moving module 151 moves upward, the sucked object, i.e., the long mat strip 310 or the short mat strip, is fixed between the suction cup 152 and the suction cup 152 and does not fall. Preferably, the carrying unit 15 in the embodiment of the present application further comprises a hot air blowing mechanism (not shown) for blowing hot air to the mat strip to melt and paste the mat strip on the photovoltaic module. The heating temperature can be controlled and adjusted by feedback of a thermocouple, which is prior art and not the innovation point of the present application. In the embodiment of the present application, the suction cups 152 are arranged in rows along the length direction of the corresponding mat strip, i.e., the short mat strip or the long mat strip 310.

[0030] In order to ensure continuous feeding of the roll 110, as shown in Figure 2 and Figure 3 , the leading end of the new roll 110 needs to be connected with the trailing end of the tape of the previous roll 110. In order to avoid interference between the tape connecting mechanism 16 and the roll 110, the tape connecting mechanism 16 is moved in space position in the embodiment of the present application. During the tape feeding process, the tape connecting mechanism 16 is on one side of the shearing mechanism 12, for example, as shown in Figure 1The rear side shown (similarly, as above, this example uses the shearing mechanism 12 of the long pad 310 located on the front right side of the frame 100; if it were the shearing mechanism 12 of the short pad 12 located on the rear right side of the frame 100, this would be the left or right side). When material strip docking is required, the material strip docking mechanism 16 moves from... Figure 1 The rear side of the shearing mechanism 12 shown moves to, as Figure 1 The right side of the shearing mechanism 12 shown (similarly, as above, this example uses a shearing mechanism 12 with a long pad 310 located at the front right end of the frame 100; if it were a shearing mechanism 12 with a short pad located at the rear right end of the frame 100, this would be the rear side). Therefore, a strip docking mechanism 16 needs to be added. The specific structure can be referenced in the strip 110 docking device described above. For example, as shown... Figure 3 As shown, a vertical linear module 161 extending along a third direction; a first telescopic cylinder 162 slidably mounted on the vertical linear module 161 and capable of telescopic movement along a first direction (similarly, as above, this is an example of a shearing mechanism 12 for a long pad 310; if it were a shearing mechanism 12 for a short pad, this would be the second direction); a second frame 163 connected to the drive end of the first telescopic cylinder 162; a second telescopic cylinder 164 mounted at the bottom of the second frame 163 and capable of telescopic movement along a third direction, i.e., vertically; a pressure band member 165 mounted at the bottom of the second telescopic cylinder 164; and a component located on the frame 100 and positioned as shown in the diagram. Figure 1 The shearing mechanism 12 shown includes a fixed or synchronously movable lower support frame 166 on its right side, and a heat-fusion component. The heat-fusion component can be a conventional thermocouple or other heating device available on the market, and can be mounted on the pressing component 165 or the lower support frame 166. After the beginning of the new strip is joined with the end of the previous strip, it is pressed and fixed onto the lower support frame 166 by the pressing component 165 and then heated and fused together.

[0031] The punching mechanism is a conventional structure, as described in existing patent literature CN117712211B. This invention will not provide a specific description or limitation. It should be noted that in the embodiments of this invention, during the laying operation of the short padding strip, the material strip can be pre-cut with clearance holes 330, or it can be cut first and then the clearance holes 330 are made. When using the method of pre-cutting with clearance holes 330, a punching mechanism is set on one side of the material strip's extension direction before the material strip enters the cutting unit. It should be noted that since the length direction of the material strip corresponds to the length direction of the padding strip, the clearance holes 330 are along the length direction of the material strip, which differs from the clearance holes 330 along the width direction of the material strip in the large roll 110. For example, taking the feeding mechanism 11 of the short pad strip as being located on the rear right side of the frame 100, the first frame 121 is located on the rear right side of the frame 100. When the strip enters the strip guide assembly 122 of the shearing mechanism 12 along the feeding mechanism 11, it is in a third direction, that is, vertically upward. Therefore, one side here is the lower rear side of the first frame 121, meaning the punching mechanism is above the strip relative to its position. In this embodiment of the invention, the punching mechanism preferably has a row of multiple clearance holes 330 units spaced apart along the length of the strip to achieve punching multiple holes at once (e.g., ...). Figure 13 The diagram shows three clearance holes 330 on a short pad. Alternatively, only one clearance hole 330 unit can be provided, with the long side of the strip passing through the punching mechanism and creating clearance holes 330 at set intervals. When using a method of cutting before creating clearance holes 330, that is, creating clearance holes 330 only when the strip needs to be on the temporary storage unit 14, the carrier plate 141 of the temporary storage unit 14 should have corresponding clearance hole 330 positions (not shown). The punching mechanism can be located above the temporary storage unit 14 but should avoid interfering with the transport unit 15. Specific details are not described in detail, but those skilled in the art can easily understand and implement this.

[0032] The photovoltaic module end strip cutting and laying machine of this invention can simultaneously feed long pads 310 and short pads of the end strip. Moreover, the feeding mechanism 11 adopts a multi-plate feeding mechanism 11, which is set in the bottom space inside the frame 100, so as not to significantly increase the volume of the entire equipment and reduce the floor space. In addition, it can feed multiple rolls at one time, which greatly improves production efficiency.

[0033] It should be understood that the foregoing detailed description of the application, rather than limiting the application, is intended to explain and describe the current implementation of the application. Therefore, any modification, equivalent replacement or improvement made without departing from the spirit and scope of the application should be included in the protection scope of the application. In addition, the appended claims of the application are intended to cover all changes and modifications falling within the scope and boundary of the appended claims, or the equivalent form of such scope and boundary.
