Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic components, and in particular to a device for placing corner protection tapes in a lamination process of photovoltaic components. Background Art

[0002] The lamination process is a core process in the photovoltaic module packaging process. The cells are stacked in double-layer glass, and all the air is exhausted to form a vacuum, which protects the cells from the external environment and increases the service life of the photovoltaic module. The corner guards at the four corners of the photovoltaic module can limit the amount of glue overflow between the two layers of glass during the lamination process, thereby achieving the purpose of limiting the lamination thickness of the module.

[0003] The Chinese invention patent with the publication number "CN116190493A" discloses an automatic assembly device for corner guards used in the lamination process of photovoltaic modules, which can realize the synchronous placement of corner guards around the photovoltaic module and the attachment of tapes to fix the corner guards at the four corners of the photovoltaic module. The corner guard process corresponding to the device disclosed in this patent document is: attach a piece of tape to each of the two arms of the corner guard, cut the tape after lamination, and then pull the corner guard backwards. The existing photovoltaic module corresponding to this corner guard installation process has four sides including two long sides and short sides of the edge tape before the corner guard is installed, and the device is required to set two sets of attachment devices for each corner of the photovoltaic module, and eight sets of attachment devices are required in one device. In addition, in order to facilitate the subsequent removal of the corner guard, the corner guard installation process of the above technical solution needs to open a groove on the outer side of the two arms of the corner guard to facilitate the subsequent cutting of the tape. On the one hand, the corner guard with a groove needs to be customized, and on the other hand, the cut tape may remain on the photovoltaic module and need to be removed later, which increases the cost and process. Moreover, the above-mentioned equipment cannot be applied to the installation of the corner guards of the existing photovoltaic modules without side tapes before the corner guards are installed. Therefore, it is necessary to provide a new corner guard tape application equipment for the photovoltaic module lamination process for the installation of the corner guards of the existing photovoltaic modules without side tapes before the corner guards are installed.

DETAILED DESCRIPTION

[0012] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0013] Example 1

[0014] This embodiment provides a photovoltaic module lamination process for placing corner tape equipment, see Figures 1 to 19 , mainly includes a first transmission module 10, four corner tape placement modules 20, four side tape attachment modules 40 and a feeding module 30.

[0015] The first transmission module 10 is arranged along Figure 1 The photovoltaic module 50 is transported in the front-to-back direction as shown (it should be noted that the front-to-back here does not mean Figure 1The front and rear sides shown in the figure are not the sides facing the reader, but the side of the device facing the reader is the front, and the side facing away from the reader is the rear) to facilitate the input and output of the photovoltaic components 50. The first transmission module 10 is used for the transportation of the photovoltaic components 50 (including the input of the photovoltaic components 50 to be laminated and the output of the laminated photovoltaic components 50) and for positioning when placing the corner protectors 60 and applying the tape. For the first transmission module 10, its structure and working principle are not described. It is an existing conventional transportation module for photovoltaic components 50. It is a prior art and is not an innovation of the present invention. It is easy for those skilled in the art to know and implement it. For the convenience of description and distinction, in this embodiment, the transportation direction of the first transmission module 10 is described as the first direction, as shown in FIG. Figure 1 The left and right directions shown are the second directions, the first direction and the second direction are perpendicular in the same horizontal plane, the vertical direction is perpendicular to the first direction and the second direction in space, and the first direction, the second direction and the vertical direction are perpendicular to each other in space, forming the three-axis directions of the triangular coordinate system. As for the corner protector 60, its structure is not described or limited, and the description of the prior art in the background technology can be referred to, which is not the innovation of the present invention.

[0016] The four corner guard tape application modules 20 in this embodiment are respectively arranged on the outside of the four corners of the first transmission module 10 and can be moved closer to or away from the corresponding corners of the photovoltaic assembly 50 to be laminated on the middle first transmission module 10 to complete the installation and fixation of the corner guard 60 and the adhesive fixation of the first tape 70. Compared with the prior art in the background technology, each corner guard 60 only needs one module to complete the installation and tape fixation of the corner guard 60, with fewer structures, lower costs, and simpler removal of the subsequent tape. Specifically, for each corner guard tape application module 20, if Figure 4 , Figure 8 , Fig. 9 and Fig.19 As shown, it mainly includes three parts: a fixed-length tape assembly 21, a corner guard placement and positioning mechanism 22, and a tape attachment mechanism 23. It should be noted that, as Fig. 9As shown, the fixed-length tape assembly 21, the corner guard placement and positioning mechanism 22 and the tape attaching mechanism 23 are installed on the same base (not marked) and are driven together to move toward or away from the corner of the photovoltaic component 50 corresponding to the corner guard tape module 20, and the corner guard placement and positioning mechanism 22 is closer to the photovoltaic component 50. When approaching, the corner guard placement and positioning mechanism 22 first contacts the photovoltaic component 50 and presses the corner guard 60 fixed thereon against the outside of the corner of the photovoltaic component 50. Then, the tape attaching mechanism 23 moves relative to the fixed-length tape assembly 21 and the corner guard placement and positioning mechanism 22 along the diagonal direction of the base or the diagonal direction of the corner guard 60 toward or away from the corner of the photovoltaic component 50 so as to adhere and fix the corner guard 60 to the corner of the photovoltaic component 50 through the first tape 70. More specifically, the corner guard placement and positioning mechanism 22 is disposed near the photovoltaic module 50 on the first transmission module 10, and is used to fix the corner guard 60 to be installed and press the corner guard 60 against the outer side of the corresponding corner of the photovoltaic module 50, so as to position the corner guard 60 at the corresponding corner of the photovoltaic module 50 before the adhesive tape is applied. The fixed-length adhesive tape assembly 21 is disposed on the side of the corner guard placement and positioning mechanism 22 away from the photovoltaic module 50, and cuts a section of the first adhesive tape 70 used to adhere and fix the corner guard 60 to the corresponding corner of the photovoltaic module 50, and folds one end of the section of the first adhesive tape 70 to form a first folded portion 71. The tape attaching mechanism 23 is flippably arranged between the fixed-length tape cut assembly 21 and the corner guard placement and positioning mechanism 22. It is used to adsorb and fix the first tape 70 to be cut when the first tape 70 is cut, and to adsorb and fix the first tape 70 after the corner guard 60 is fixed to the corner of the photovoltaic component 50, and then flip the cut first tape 70 to attach it to the corner guard 60 and the photovoltaic component 50. Specifically, the middle section of the first tape 70 is pressed against the outside of the top corner of the corner guard 60 and the two ends of the first tape 70 are folded in the same direction with the top corner of the corner guard 60 as the folding starting point and are respectively flatly fixed on the upper and lower surfaces of the photovoltaic component 50, that is, the first tape 70 is pasted along the diagonal of the corner guard 60.

[0017] like Figure 4 As shown, the fixed-length tape assembly 21 mainly includes five parts: a first tape reel 211, an upper clamping mechanism 214, a winding and folding mechanism 212, a lower clamping mechanism 215 and a tape-breaking mechanism 213. Specifically, the first tape reel 211 is a conventional disc-shaped structure that can rotate around a horizontal line, and the first tape roll is installed on the first tape reel 211. The first tape reel 211 of this embodiment is arranged at the top, and releases the first tape 70 downward. The upper clamping mechanism 214, the winding and folding mechanism 212, the lower clamping mechanism 215 and the tape-breaking mechanism 213 are all arranged below the first tape reel 211. The winding and folding mechanism 212 is arranged on the tape feeding path of the first tape reel 211, specifically as shown in the figure. Figure 8The folding mechanism 212 is provided to fold the first adhesive tape 70 from the first adhesive tape reel 211 to the free end of the first adhesive tape 70 to be cut. Figure 8 The lower end shown is directed toward the end to be cut off. Figure 8 The lower clamping mechanism 215 can be vertically lifted and lowered below the first adhesive tape reel 211. The lower clamping mechanism 215 is used to clamp the free end of the folded first adhesive tape 70 to form the first folded portion 71. At the same time, when descending downward, the first adhesive tape 70 is pulled downward by a certain length so that the end to be cut of the first adhesive tape 70 is exactly on the same horizontal plane as the tape cutting mechanism 213. The upper clamping mechanism 214 is provided between the first adhesive tape reel 211 and the folding mechanism 212 to clamp the upper end of the end to be cut of the first adhesive tape 70. The tape cutting mechanism 213 is arranged between the upper clamping mechanism 214 and the lower clamping mechanism 215 and is close to the upper clamping mechanism 214. It should be noted that the tape cutting mechanism 213 is located on the side of the first tape 70 between the upper clamping mechanism 214 and the lower clamping mechanism 215, and can be driven to translate in the horizontal direction toward or away from the first tape 70, and is used for making a translational movement in the direction close to the first tape 70 after the first tape 70 is lowered and stretched to a preset length by the lower clamping mechanism 215 to cut off the end of the first tape 70 to be cut.

[0018] Specifically, Figure 4 and Figure 6 As shown, the folding mechanism 212 includes a first driving member 2121 and a first clamping member 2122 and a second clamping member 2123 driven by the first driving member 2121 to move relative to each other. The first clamping member 2122 and the second clamping member 2123 have a separated open state and a close closed state. In the open state, the free end of the first adhesive tape 70 passes between the first clamping member 2122 and the second clamping member 2123. For ease of description and distinction, the clamping end of the first clamping member 2122 is also implemented as shown in FIG. Figure 6 The front end shown is the first clamping section (not shown), and the clamping end of the second clamping member 2123 is also Figure 6 The front end shown is implemented as a second clamping section (not shown). In the closed state, the first clamping section and the second clamping section are clamped on both sides of the free end of the first adhesive tape 70. Figure 6The front and rear sides shown are staggered in the vertical direction, that is, one above and one below, so that the free end of the first adhesive tape 70 can be folded toward the side of the end to be cut. For example, in this embodiment, the first clamping section is on the top and the second clamping section is on the bottom. In this way, the free end of the lower end of the first adhesive tape 70 is folded by the clamping force of the first clamping section and the second clamping section, specifically folded upward. Preferably, the first clamping section and the second clamping section are cylindrical structures, similar to chopsticks. For the first driving member 2121, an existing conventional cylinder can be selected. It should be noted that in this embodiment, the folding mechanism 212 can be translated in the horizontal plane, specifically horizontally approaching or horizontally moving away from the direction of the first adhesive tape 70 between the upper clamping mechanism 214 and the lower clamping mechanism 215. The horizontal movement away is to prevent the lower clamping mechanism 215 and the first adhesive tape 70 from interfering with the movement in the process of the lower clamping mechanism 215 clamping the folded free end to form the first folding portion 71 and pulling it downward to a preset length. In this embodiment, Figure 6 As shown, the rolling and folding mechanism 212 and the tape-breaking mechanism 213 are both arranged on the rear side shown in the figure, and the rolling and folding mechanism 212 is located above the tape-breaking mechanism 213 .

[0019] For the upper clamping mechanism 214, if Figure 4 and Figure 6 As shown, the first adhesive tape 70 includes two surfaces along the first adhesive tape 70, that is, Figure 8 The fixed pressing plate 2141 and the movable pressing plate 2142 are arranged relatively on the left and right surfaces, and the movable pressing plate 2142 is driven to move closer to or away from the fixed pressing plate 2141. Figure 8 The second driving member 2143 is shown as being translated left and right. In the figure, the fixed pressing plate 2141 and the movable pressing plate 2142 are arranged with a relative spacing therebetween, and the free end of the first adhesive tape 70 passes downward through the spacing therebetween. Preferably, a concave portion facing away from the movable pressing plate 2142 is formed on the side of the fixed pressing plate 2141 facing the movable pressing plate 2142. Figure 8 As shown, it is recessed to the right and extends along the direction of the tape feeding path. Figure 8As shown, the guide groove (not shown) extending downward and penetrating therethrough is formed, correspondingly, a pressing protrusion (not shown) protruding and extending toward the fixed pressing plate 2141 and matching the guide groove is formed on one end of the movable pressing plate 2142 facing the fixed pressing plate 2141, and the pressing protrusion is embedded in the guide groove to clamp and fix the upper end of the end to be cut of the first adhesive tape 70. For the second driving member 2143, the conventional cylinder can be selected in the same way. Preferably, a plurality of first adsorption holes 21411 connected to the guide groove are formed on the fixed pressing plate 2141, and the purpose of the first adsorption holes 21411 is to be able to adsorb and fit the first adhesive tape 70 to the fixed pressing plate 2141 when the movable pressing plate 2142 is separated from the first adhesive tape 70. Specifically, when the lower clamping mechanism 215 clamps the first folding portion 71 and pulls it downward, the first adhesive tape 70 is adsorbed by the first adsorption hole 21411 and adheres to the guide groove on the fixed pressure plate 2141, which not only serves as a guide but also prevents the first adhesive tape 70 from escaping from the guide groove of the fixed pressure plate 2141, which is not conducive to the subsequent movable pressure plate 2142 to press the first adhesive tape 70.

[0020] For the lower clamping mechanism 215, if Figure 5 As shown, it mainly includes a clamping assembly 2151 and a third driving member 2152. Among them, the clamping assembly 2151 of this embodiment can be selected as an existing conventional pneumatic clamping block mechanism, specifically, including the following Figure 5The first clamp block 21511 and the second clamp block 21512 are arranged opposite to each other on the left and right, and the clamp block cylinder 21513 is arranged below the first clamp block 21511 and the second clamp block 21512 to drive the first clamp block 21511 and the second clamp block 21512 to move closer to or away from each other. The first clamp block 21511 and the second clamp block 21512 extend upward and have clamping sections formed on their upper ends. For the convenience of description and distinction, the clamping section on the upper end of the first clamp block 21511 is described as the third clamping section 215111, and the clamping section on the upper end of the second clamp block 21512 is described as the fourth clamping section 215121. The third clamping section 215111 and the fourth clamping section 215121 both protrude and extend outward. That is to say, the first clamping block 21511 and the second clamping block 21512 are both in an inverted L-shape, which is wide at the upper end and narrow at the lower end. When the third clamping section 215111 of the first clamping block 21511 and the fourth clamping section 215121 of the second clamping block 21512 are clamped, there is a gap between the third clamping section 215111 of the first clamping block 21511 and the bottom of the fourth clamping section 215121 of the second clamping block 21512. The gap is formed as an avoidance space (not marked), which is intended to provide avoidance for the folding mechanism 212. That is, after the folding mechanism 212 clamps and folds the free end of the first adhesive tape 70 (the first folded portion 71 is not formed at this time), the lower clamping mechanism 215 clamps the folded free end and the unfolded portion so that the two are close to each other to form the first folded portion 71. The folding mechanism 212 is not loosened at this time, that is, it is in the avoidance space. After the first folded portion 71 is formed, when the lower clamping mechanism 215 pulls the first adhesive tape 70 downward, the folding mechanism 212 needs to withdraw backward from the avoidance space first. As for the third driving member 2152, its purpose is to drive the clamping assembly 2151 to move upward, that is, close to the folding mechanism 212 to clamp the folded free end to form the first folded portion 71 and clamp it, or to move downward, that is, away from the folding mechanism 212 to pull the first adhesive tape 70 downward to a preset length. For the third driving member 2152, it exemplarily includes a rotating motor and a screw rod combination and a vertical slide rail (not marked), the screw rod (not marked) is arranged vertically and connected to the driving end of the rotating motor (not marked), and the left end of the clamping block cylinder 21513 of the clamping assembly 2151 is slidably connected to the vertical slide rail through a slider (not marked), and no detailed description and limitation are given. Preferably, the end surface of the third clamping section 215111 of the first clamping block 21511 facing the second clamping block 21512 and the end surface of the fourth clamping section 215121 of the second clamping block 21512 facing the first clamping block 21511 are respectively formed with rack-shaped anti-skid patterns (not marked) to increase the friction during clamping and improve the clamping reliability.

[0021] For the tape cutting mechanism 213, if Figure 6As shown, this embodiment is exemplified as an existing conventional pneumatic scissor mechanism, specifically, it includes a pneumatic scissor 2131 that can be opened and closed and a pneumatic scissor 2131 that is driven to move toward or away from the first adhesive tape 70, that is, Figure 8 The fourth driving member 2132 shown as horizontally moving in the front-rear direction. For the fourth driving member 2132, an existing conventional cylinder can be selected.

[0022] As for the tape attaching mechanism 23, in this embodiment, the tape attaching mechanism 23 is installed together with the fixed-length tape assembly 21 and can be synchronously moved horizontally toward or away from the photovoltaic assembly 50, and the tape attaching mechanism 23 is arranged on the side of the lower clamping mechanism 215 close to the photovoltaic assembly 50, that is, Figure 8 Moreover, the lower clamping mechanism 215 can move horizontally toward or away from the tape attaching mechanism 23, that is, the lower clamping mechanism 215 can move along the direction shown in FIG. Figure 8 It moves horizontally in the left and right directions as shown. That is to say, when the adsorption end of the tape attaching mechanism 23 rotates to face the lower clamping mechanism 215, there is a distance between the two. At this time, after the lower clamping mechanism 215 is translated toward one side of the tape attaching mechanism 23, the first tape 70 will be adsorbed by the adsorption end of the tape attaching mechanism 23, and then the tape cutting mechanism 213 will cut off the end of the first tape 70 to be cut. It should be noted that when the lower clamping mechanism 215 moves toward or away from the tape attaching mechanism 23, the upper clamping mechanism 214, the winding and folding mechanism 212, the tape cutting mechanism 213 and the first tape reel frame 211 move together, that is to say, the upper clamping mechanism 214, the winding and folding mechanism 212, the tape cutting mechanism 213 and the first tape reel frame 211 and the lower clamping mechanism 215 are installed on the same fixed plate (exemplarily as shown in Figure 4 The adhesive tape attaching mechanism 23 is mounted on another fixing plate (exemplarily as shown in FIG. Figure 4 The two fixing plates are slidably connected. Specifically, Figure 7 As shown, the tape attaching mechanism 23 includes an attaching component 231 and a horizontal rotating driving member 232. The horizontal rotating driving member 232 can rotate as shown in FIG. Figure 7 The horizontal axis extending forward and backward as shown rotates to drive the attachment assembly 231 to rotate synchronously so that its attachment end faces as shown in FIG. Figure 4 The lower clamping mechanism 215 on the left side shown or facing as shown Figure 4 The photovoltaic module 50 on the right side is shown Figure 1 The horizontal rotation driving member 232 is a conventional rotary motor.

[0023] For the attachment component 231, Figure 7As shown, it mainly includes a mounting base plate 2311, two adsorption blocks 2312, two adhesive tape mechanisms, two elastic abutting components 2314 and a sliding plate 2315. Among them, the mounting base plate 2311 is connected to the horizontal rotation driving member 232 and has a horizontal extension in the middle, that is, Figure 7 The two adsorption blocks 2312 are respectively fixed to the upper and lower ends of the opening of the corresponding avoidance groove 23111 of the mounting substrate 2311, and the outer end surfaces of the two adsorption blocks 2312 are also as shown. Figure 7 The left end face shown is implemented as an adsorption surface. A plurality of blowing and suction holes 23121 are provided on the adsorption surface of any adsorption block 2312, the purpose of which is to provide suction when the attachment component 231 adsorbs and fixes the first tape 70 and to blow the first tape 70 away from the adsorption surface of the adsorption block 2312 when the first tape 70 is attached and fixed to the upper and lower surfaces of the corner protector 60 and the photovoltaic component 50. Preferably, the two attachment blocks can be moved vertically to adjust the distance between them, in order to match first tapes 70 of different lengths. The two tape-applying mechanisms are fixed relatively and at intervals on the upper and lower inner walls of the opening of the avoidance groove 23111, and any tape-applying mechanism includes a mounting block (not shown) horizontally fixed at the opening of the avoidance groove 23111 and a mounting block (not shown) installed at the outer end of the mounting block, i.e. Figure 7 The right end shown can be rotated relative to the mounting block as shown. Figure 7 The first attaching roller 2313 rotates horizontally in the front-back direction as shown. The two elastic abutting members 2314 are arranged oppositely on both sides of the thickness direction of the mounting substrate 2311. Figure 7 The front and rear sides shown in the figure and one end of any elastic supporting member 2314 are also as shown in the figure. Figure 7 The left end shown is movably connected to the left end of the mounting substrate 2311, and the other end is also as shown in FIG. Figure 7The right end shown is connected to the inner end of the sliding plate 2315. In the initial state, the sliding plate 2315 is under the biasing force of the elastic supporting part 2314 and is located between the two first attaching rollers 2313 of the two tape attaching mechanisms. When the horizontally rotating driving member 232 drives the adsorption surface of the attaching component 231 toward the corresponding corner of the photovoltaic component 50 where the corner guard 60 is to be installed and the tape attaching mechanism 23 is driven to move close to the corner guard 60 of the corresponding corner of the photovoltaic component 50, the middle section of the first tape 70 adsorbed by the two adsorption blocks 2312 is pressed by the two first attaching rollers 2313 at the top corner of the corresponding corner guard 60 and the sliding plate 2315 is compressed by the corresponding corner guard 60 and retracts toward the avoidance groove 23111, and the corner guard 60 enters the avoidance groove 2311. 1, so that the two ends of the first adhesive tape 70 are flattened on the upper and lower surfaces of the corner protector 60 under the action of the inner wall of the avoidance groove 23111, and the two ends of the first adhesive tape 70 extend horizontally along the diagonal line of the corner protector 60 toward the inner side of the photovoltaic module 50. In this process, the two first attachment rollers 2313 of the two adhesive tape attachment mechanisms roll and press against the outer surfaces of the two ends of the first adhesive tape 70 respectively, so as to fold the two ends of the first adhesive tape 70 whose middle section has been attached to the top corner of the corner protector 60 from the outside to the inside and flatten and adhere them to the upper and lower surfaces of the photovoltaic module 50. For the elastic abutting component 2314, if Figure 7 As shown, including an Figure 7 The cylindrical supporting rod 23141 extending horizontally in the left and right directions and the elastic member 23142 (exemplarily a tubular straight spring) sleeved on the outer periphery of the supporting rod 23141 are shown, the left end of the supporting rod 23141 is movably inserted into the left end of the mounting base plate 2311, i.e., the end opposite to the escape groove 23111, the right end of the supporting rod 23141 is fixed to the inner end, i.e., the left end, of the sliding plate 2315, and the axis of the supporting rod 23141 is parallel to the extension direction, i.e., the length direction, of the escape groove 23111. The elastic member 23142 applies a biasing force to the sliding plate 2315 so that the sliding plate 2315 tends to the notch of the escape groove 23111 and is located between the two first attachment rollers 2313.

[0024] The corner guard placement and positioning mechanism 22 can be driven to move closer to or away from the corresponding corner of the photovoltaic component 50 and press the corner guard 60 against the corresponding corner of the photovoltaic component 50 when moving closer. It should be noted that the corner guard placement and positioning mechanism 22, the fixed-length tape assembly 21 and the tape attachment mechanism 23 of this embodiment are arranged on the same base plate and can be driven to move synchronously closer to or away from the corresponding corner of the photovoltaic component 50. The specific structure is not described and limited in detail, and reference can be made to the prior art mentioned in the background technology. An exemplary method, such as Fig. 9 As shown, the corner guard placement and positioning mechanism 22 of this embodiment includes two opposite and spaced apart (i.e., Fig. 9The front and rear sides of the corner guard 60 are relatively spaced apart to avoid interference with the side of the photovoltaic module 50. A corner guard fixing platform 221 is provided and a pressing block 222 is provided on any corner guard fixing platform 221, which can be lifted and lowered vertically and can rotate around a vertical line. A fixing groove 2211 is provided on the upper surface of any corner guard fixing platform 221 and on one side close to the other corner guard fixing platform 221. The fixing groove 2211 is concave downward and matches the end of one of the arms of the corner guard 60 away from the top corner of the corner guard 60. After the corner guard 60 is placed in the two fixing grooves 2211 of the two corner guard fixing platforms 221, the two pressing blocks 222 are pressed against the upper surfaces of the two arms of the corner guard 60 respectively. A rotating lifting driving member (not shown in the figure, an example of which can be a conventional motor screw mechanism) is provided in any corner guard fixing platform 221 for driving the corresponding pressing block 222 to rotate and lift. It should be noted that the two corner guard fixing platforms 221 can be driven to rise and fall synchronously in the vertical direction. The lifting drive mechanism (not shown) of the corner guard fixing platform 221 is not described or limited, and is an existing conventional lifting cylinder. Optionally, a corner support positioning platform 90 supported on the bottom surface of the photovoltaic module 50 is also provided on the fixed base (not shown) of the corner guard fixing platform 221 (not described in detail, refer to the positioning mechanism recorded in the prior art in the background technology). The corner support positioning platform 90 and the two corner guard fixing platforms 221 are arranged relative to each other, that is, Fig. 9 As shown in the figure, the left and right sides are arranged oppositely, and the corner fixing platform 221 is close to the tape attaching mechanism 23, that is, Fig. 9 As shown on the left side, the corner support positioning platform 90 is away from the tape attaching mechanism 23, that is, Fig. 9 The right side shown is the side close to the photovoltaic component 50 .

[0025] The corner guard tape application device of this embodiment is aimed at photovoltaic modules that do not have edge tape before corner guard installation. In order to improve the lamination effect and reduce the occurrence of glue leakage, it is necessary to paste a C-shaped second tape 80 on the two long sides of the photovoltaic module 50. For details, see Figure 2 The first adhesive tape 70 is respectively attached to the corner guards 60 at the four corners of the photovoltaic module 50, and a set of long sides of the photovoltaic module 50 is also as shown in FIG. Figure 2 A second tape 80 is provided at each of the left and right ends of the upper side and the left and right ends of the lower side. There are four first tapes 70 and four second tapes 80 in total. That is, a second tape 80 is provided at a preset distance (not described or limited, and those skilled in the art can choose the design according to actual conditions) from any corner guard 60 on each long side. The second tape 80 is attached by the side tape attaching module 40, and correspondingly, each second tape 80 corresponds to a side tape attaching module 40. That is, a group of corresponding sides of the two ends of the photovoltaic module 50 corresponding to the first direction are specifically two long sides, that is, Figure 2A side tape attaching module 40 is provided on the outer sides of the left and right ends of any of the upper and lower sides, and the side tape attaching module 40 is located on the inner side of the corner tape attaching module 20. The problem of glue leakage during the lamination process of the photovoltaic module 50 can be further reduced, and the lamination quality of the photovoltaic module 50 can be improved.

[0026] The side tape attaching module 40 of this embodiment is as follows: Figures 10 to 13 As shown, it mainly includes a second tape reel 41, a plurality of guide wheels 42, a pressure head mechanism 44, a lower attachment mechanism 43, an upper attachment mechanism 45, a winding mechanism 48, a pressure rod mechanism 47 and a tape cutting mechanism 46. The second tape 80 rolls are installed on the second tape reel 41, and the second tape reel 41 is arranged as shown in FIG. Fig.10 The lower attachment mechanism 43, the pressure head mechanism 44, the second tape reel 41 and part of the guide wheel 42 are synchronously lifted and lowered and moved along the first direction, that is, as shown in FIG. Fig.10 Several guide wheels 42 are arranged on the tape feeding path of the second tape reel 41 to guide the tightening of the second tape 80, for example, Fig.10 and Fig.11 As shown, four guide wheels 42 are included, all of which are arranged on the left side of the second tape reel frame 41, and the four guide wheels 42 are arranged in sequence from bottom to top, and the guide wheel 42 at the second lowest position in height is located at the lowest position and on the left side of the guide wheels 42 at other positions.

[0027] like Fig.10 As shown, the lower attachment mechanism 43 is disposed at the upper left end of the guide wheel 42 at the highest position, that is, the rear end of the guide wheel 42 at the end of the adhesive feeding path, and is used to attach the second adhesive tape 80 to the lower surface of the photovoltaic module 50. Specifically, as Fig.12 As shown, it includes a guide plate 431 extending obliquely upward and a second attaching roller 432 arranged at the top of the guide plate 431 and rotatable around a horizontal axis. After the second adhesive tape 80 passes through the guide plate 431, the adhesive surface faces upward. A guide protrusion 4311 protruding upward and extending from the bottom end of the guide plate 431 to the top is arranged in the middle of the upper surface of the guide plate 431. The width of the guide protrusion 4311 is consistent with the width of the second adhesive tape 80, and a guide inclined surface 4312 extending obliquely downward is arranged at the top of the guide plate 431. A blowing hole 4313 for blowing air to the second adhesive tape 80 so that the second adhesive tape 80 is horizontal is provided on the guide inclined surface 4312, that is, at the position of the guide plate 431 close to the second attaching roller 432. The pressure head mechanism 44 is arranged on the side of the lower attaching mechanism 43, specifically as shown in the figure. Fig.10 The guide wheel 42 at the right side and the highest position shown in the figure is also the upper right side of the guide wheel 42 at the end of the glue feeding path. Fig.10As shown, it includes a pressing driving member 441 arranged obliquely downward and a pressing head 442 (the end surface is a sphere) arranged at the lower end of the pressing driving member 441. The pressing head 442 is driven by the pressing driving member 441 before the lower attaching mechanism 43 attaches the adhesive tape to press against the second adhesive tape 80 on the guide wheel 42 at the end of the adhesive feeding path, that is, the guide wheel 42 at the highest position in the figure, and is released when the lower attaching mechanism 43 attaches the adhesive tape. For the pressing driving member 441, an existing conventional cylinder can be selected.

[0028] It should be noted that, in this embodiment, the lower attaching mechanism 43, the pressing head mechanism 44, the second tape reel frame 41 and part of the guide wheels 42 (specifically, the three guide wheels 42 at the lowest position, the highest position and the second highest position in height) are installed on the same fixed plate (not shown) and can be synchronously lifted and lowered vertically and along the first direction, that is, Fig.10 In addition, in this embodiment, the tape cutting mechanism 46, the pressure rod mechanism 47, the winding mechanism 48 and the upper attaching mechanism 45 are installed on the same fixed plate (not shown) and can be synchronously lifted and lowered vertically. Preferably, the two fixed plates can be relatively movable to adjust the spacing between the upper attaching mechanism 45 and the lower attaching mechanism 43. It should be noted that this adjustment is performed before the equipment starts to operate, and the two are not allowed to be adjusted during the operation.

[0029] Specifically, Fig.10 As shown, the tape cutting mechanism 46 is arranged near the lower attaching mechanism 43, specifically on the left side of the lower attaching mechanism 43, and the tape cutting mechanism 46 can be lifted and lowered vertically. The lifting and lowering here is different from the synchronous lifting and lowering of the tape cutting mechanism 46, the pressure rod mechanism 47, the winding mechanism 48 and the upper attaching mechanism 45. The lifting and lowering here refers to the tape cutting mechanism 46 relative to other mechanisms, namely the pressure rod mechanism 47, the winding mechanism 48 and the upper attaching mechanism 45. After the lower attaching mechanism 43 has attached the second tape 80 on the lower surface of the photovoltaic module 50 and the second tape 80 is pulled out of a predetermined length along the first direction (it should be noted that the pulling out of the second tape 80 here is achieved by the horizontal movement of the entire side tape attaching module 40), the tape cutting mechanism 46 cuts off the end of the second tape 80 to be cut.

[0030] The upper attaching mechanism 45 is disposed on the side of the tape cutting mechanism 46 away from the lower attaching mechanism 43. Fig.10 As shown in the figure, it should be noted that the upper attaching mechanism 45 is higher than the lower attaching mechanism 43 in height, and the upper attaching mechanism 45 can be driven to move in a first direction close to or away from the tape cutting mechanism 46 to horizontally attach the upper end of the second tape 80 to the upper surface of the photovoltaic module 50. It should be noted that the upper attaching mechanism 45 is close to the tape cutting mechanism 46 in the initial position and moves away from the tape cutting mechanism 46 during the tape attaching process, that is, Fig.10Move to the left as shown. Fig.13 As shown, the upper attaching mechanism 45 includes a mounting base 451 and a third attaching roller 452 disposed on a side of the mounting base 451 away from the tape cutting mechanism 46 and rotatable about a horizontal line to horizontally attach the second tape 80 to the upper surface of the photovoltaic module 50. The mounting base 451 is provided with a plurality of second adsorption holes 453 for adsorbing and fixing the second tape 80 to the upper attaching mechanism 45 before the second tape 80 is cut.

[0031] like Fig.10 and Fig.13 As shown, the winding mechanism 48 is disposed on one side of the upper attaching mechanism 45 close to the tape cutting mechanism 46 and can be wound as shown in FIG. Fig.13 The horizontal line in the front-to-back direction (the horizontal line is parallel to the axis of the third attaching roller 452) is flipped to fold the cut end of the second adhesive tape 80 to form a second folded portion 81, wherein the second adsorption hole 453 is arranged close to one side of the winding mechanism 48, and the cut end of the second adhesive tape 80 is placed on the top of the winding mechanism 48 after being cut. Fig.13 The right end to the other end is Fig.13 The left end shown is folded over.

[0032] For the pressing rod mechanism 47, one side of the upper attaching mechanism 45 disposed at the initial position is specifically as follows: Fig.10 The rear side shown in the figure can be lifted vertically and moved horizontally toward or away from the upper attachment mechanism 45 in the initial position. Fig.10 As shown, the forward movement is similarly explained. It should be noted that the lifting and lowering here are relative to other mechanisms, namely the tape cutting mechanism 46 and the lower attaching mechanism 43. The pressure rod mechanism 47 presses on the second tape 80 adsorbed and fixed on the upper attaching mechanism 45 after the tape cutting mechanism 46 cuts off the second tape 80 and before the winding mechanism 48 flips over to form the second folding portion 81, and releases the second tape 80 after the second folding portion 81 is formed. The second adsorption hole 453 breaks the vacuum to release the second tape 80 after the pressure rod mechanism 47 releases the second tape 80. The upper attaching mechanism 45 is driven to move horizontally along the first direction relative to the tape cutting mechanism 46 and the pressure rod mechanism 47 so that the third attaching roller 452 presses on the second tape 80 to complete the sticking of the second tape 80 on the upper surface of the photovoltaic module 50. Specifically, as Fig.11As shown, the pressure rod mechanism 47 includes a vertical cylinder 471 that can be lifted vertically, a horizontal cylinder 472 that can be extended horizontally, and a rod body 473 that is horizontally fixed on the side of the horizontal cylinder 472 facing the upper attachment mechanism 45. Before the end of the second tape 80 to be cut is cut, the rod body 473 is retracted. After the second tape 80 is cut and before the winding mechanism 48 winds it, the rod body 473 is driven by the horizontal cylinder 472 to extend and be located above the second tape 80 and then lowered by the vertical cylinder 471 so that the rod body 473 is pressed on the second tape 80.

[0033] For the convenience of description and distinction, the horizontal driving member that drives the lower attaching mechanism 43, the pressure head mechanism 44, the second tape reel 41 and the guide wheel 42 to move horizontally synchronously is described as the first horizontal driving member 49, the horizontal driving member that drives the upper attaching mechanism 45 to move in the horizontal direction is described as the second horizontal driving member 411, the lifting driving member that drives the lower attaching mechanism 43, the pressure head mechanism 44, the second tape reel 41 and the guide wheel 42 to rise and fall synchronously is described as the first vertical driving member 410, and the lifting driving member that drives the lower attaching mechanism 43, the tape cutting mechanism 46 and the pressure rod mechanism 47 to rise and fall synchronously is described as the second vertical driving member 412. The first horizontal driving member 49, the second horizontal driving member 411, the first vertical driving member 410 and the second vertical driving member 412 of this embodiment can all be cylinders.

[0034] For the winding mechanism 48, Fig.13 As shown, it includes a winding shaft 4811 fixed on the mounting base 451 and can be wound around a horizontal line, that is, as shown in FIG. Fig.10 The winding motor 481 extending horizontally forward and backward and rotating and an L-shaped winding block 482 connected to the winding shaft 4811 are shown. The winding motor 481 drives the winding block 482 toward one side of the mounting base 451, that is, Fig.13 The second folding portion 81 is shown to be turned leftward to fold the cut end of the second adhesive tape 80 placed thereon to the left to form the second folding portion 81, and the axis of the winding shaft 4811 of the winding motor 481 is parallel to the axis of the third attachment roller 452. Specifically, a relief groove (not shown) extending downward and concave to the left is opened at the right end of the mounting base 451, and the winding shaft 4811 is rotatably arranged on the relief groove, and the winding block 482 lies flat, that is, the opening faces upward and is connected to the bottom of the winding shaft 4811. It should be noted that the relief groove does not interfere when the winding shaft 4811 rotates to drive the winding block 482 to turn over.

[0035] For the tape cutting mechanism 46, an existing conventional vertically retractable cutter may be selected, and the specific structure is not described and limited, and it is easy for those skilled in the art to know and implement it.

[0036] like Fig.19As shown, a side tape attaching module 40 and a corner tape attaching module 20 of this embodiment are installed on the same fixed base (not shown), and the fixed base can move horizontally along a first direction and a second direction perpendicular to the first direction so that the corner tape attaching module 20 and the side tape attaching module 40 move closer to or away from the corner position of the photovoltaic component 50. The side tape attaching module 40 is arranged on a side edge of the fixed base close to the photovoltaic component 50, and the corner tape attaching module 20 is arranged along the diagonal of the fixed base and can move horizontally closer to or away from the side tape attaching module 40 along the diagonal direction of the fixed base, that is, it can move along the diagonal direction of the corresponding corner guard 60 to achieve the pasting and fixing of the first tape 70 on the corner guard 60.

[0037] The feeding module 30 of this embodiment includes three parts, such as Figure 1 and Figures 14 to 18 As shown, one part is a vibration loading assembly 31 for feeding the corner protector 60, another part is a first loading assembly 32 for picking up and placing the corner protector 60 corresponding to two corners of one side (in this embodiment, the side close to the vibration loading assembly 31) of the photovoltaic module 50, and another part is a second loading assembly 33 for picking up and placing the corner protector 60 corresponding to two corners of another side (in this embodiment, the side away from the vibration loading assembly 31). The vibration loading assembly 31 includes a first side ( Figure 1 The left side is exemplified in the figure) on the outside, that is, away from the first transmission module 10, a silo 311 for filling the corner guard 60, and a flexible vibration plate 312 arranged on the inside, that is, close to the first transmission module 10 and located below the discharge port of the silo 311 and below the first loading assembly 32, and a camera device ( Figure 1). As for the flexible vibration disk 312, its structure and working principle are not described or limited here. It is an existing conventional flexible vibration device, which can be easily known and implemented by those skilled in the art. Its purpose is to vibrate the corner protector 60 sent out from the discharge port of the silo 311 to a horizontal state, so that the first loading assembly 32 and the second loading assembly 33 can subsequently absorb the corner protector 60 for loading. The camera device is used to shoot the actual posture of the corner protector 60 on the flexible vibration disk 312, that is, the direction of the opening of the corner protector 60. In order to make the absorbed corner protector 60 correspond to the corresponding corner of the photovoltaic component 50, after the first loading assembly 32 and the second loading assembly 33 absorb the corner protector 60 from the flexible vibration disk 312, the posture of the corner protector 60 needs to be adjusted so that the posture of the corner protector 60 matches the corresponding corner of the photovoltaic component 50. In this embodiment, the camera device is connected to both the first loading assembly 32 and the second loading assembly 33 in communication. After the first loading assembly 32 and the second loading assembly 33 absorb the corner protector 60, the actual position of the corner protector 60 during absorption is compared with the position of the corresponding corner of the photovoltaic assembly 50. If they are consistent, the first loading assembly 32 and the second loading assembly 33 do not need to adjust the position of the corner protector 60; if they are inconsistent, the position of the corner protector 60 needs to be adjusted. Exemplarily, the camera device is an existing conventional industrial camera, and the specific structure and working principle are not described and limited. They are existing technologies and are not the innovation of the present invention.

[0038] As for the first loading assembly 32 and the second loading assembly 33, the two are different in structure and setting position. Fig.14 and Fig.15 As shown, the first loading assembly 32 includes a first truss 321 and two first suction members 322 slidably mounted on the first truss 321. For the first truss 321, it extends along the first direction, and a U-shaped frame 320 is also provided at the bottom of the first truss 321. The U-shaped frame 320 is arranged above the flexible vibration disk 312 and its opening edge faces one side of the flexible vibration disk 312. The first truss 321 is arranged on the opening edge of the U-shaped frame 320 and forms a square frame body with the U-shaped frame 320. The first truss 321 can be driven to slide horizontally along the U-shaped frame 320 (the sliding direction is perpendicular to the first direction, that is, along the second direction). In order to achieve one side of the photovoltaic assembly 50, that is, as shown in Figure 1 As shown, the side close to the vibration feeding assembly 31 is as shown in FIG. Figure 1In the transplanting and loading of the corner guards 60 at the two corners at the front and rear ends of the left side shown in the figure, the number of the first suction members 322 in this embodiment is two, and the two first suction members 322 are relatively spaced and independently driven to be freely moved along the first direction relative to the first truss 321 and arranged on the first truss 321, and any first suction member 322 can be driven to rise and fall vertically and rotate around a vertical line. In other words, the first loading assembly 32 is actually composed of the first truss 321, the two first suction members 322, the two first horizontal displacement driving members 325, the two first vertical displacement driving members 324 and the two first vertical rotation driving members 323. Any first vertical rotation driving member 323 drives a first suction member 322 to rotate around a vertical line, any first vertical displacement driving member 324 drives a first suction member 322 and a first vertical rotation driving member 323 to rise and fall vertically as a whole, and any first horizontal displacement driving member 325 drives a first suction member 322, a first vertical rotation driving member 323 and a first vertical displacement driving member 324 to move horizontally as a whole, that is, in the first direction.

[0039] like Fig.16 As shown, the second loading assembly 33 of this embodiment includes a second truss 330, two second suction members 331, a second transmission module 332 and two third suction members 333. The second truss 330 is arranged parallel to the first truss 321, that is, extends along the first direction, except that the second truss 330 is arranged at the same position as the first truss 321. Figure 1 As shown in the right end, two second suction members 331 can be driven to slide along the first direction on the second truss 330, and the second transmission module 332 is arranged across the first transmission module 10 and the photovoltaic components 50 thereon, that is, the second transmission module 332 extends along the second direction. The two third suction members 333 are arranged on the first truss 321 like the two first suction members 322. In this embodiment, the two third suction members 333 are mainly used to absorb the corner protector 60 from the flexible vibration plate 312 and adjust the posture of the corner protector 60 and then transfer it to the carrier 3321 on the second transmission module 332. The carrier 3321 equipped with the corner protector 60 is transferred from the second transmission module 332 to the carrier 3321 on the second transmission module 332. Figure 1 or Fig.17 The left side, i.e., the side close to the vibrating feeding assembly 31, specifically, the flexible vibrating plate 312, is transported to the right side, i.e., the side away from the flexible vibrating plate 312, and then the empty carrier 3321 is transported from the right side to the left side. The two second suction members 331 are used to absorb and transfer the corner guard 60 on the carrier 3321 to the corresponding end when the carrier 3321 is transported to the right side of the second transmission module 332. Figure 1The two corner guard tape modules 20 at the front and rear ends of the right side of the device are placed on the corner guard positioning mechanism 22. For the second transmission module 332, its structure is the same as that of the first transmission module 10, that is, both are guide rail or transmission belt type transmission structures. In this embodiment, the guide rail transmission structure is exemplified, and the carrier 3321 is slidably set on the guide rail. In some preferred embodiments, the number of carriers 3321 is two, and the two carriers 3321 are arranged relatively spaced apart and during operation, one of the carriers 3321 is on the left side of the second transmission module 332, that is, at the pick-up and placement position of the third suction member 333 close to the side of the flexible vibration disk 312, and the other carrier 3321 is on the right side of the second transmission module 332, that is, at the pick-up and placement position of the second suction member 331 away from the side of the vibration feeding assembly 31. Efficiency can be greatly improved.

[0040] For vehicle 3321, if Fig.17 and Fig.18 As shown, any carrier 3321 is a flat structural member, on which two positioning grooves 33211 are arranged oppositely and spaced apart and extend downwardly concavely. The shape and size of the positioning grooves 33211 are consistent with the shape and size of the corner protector 60, and the position of the positioning grooves 33211 is consistent with the position of the corner protector 60. Figure 1 The posture of the corners at the front and rear ends of the right side of the photovoltaic component 50 shown corresponds to that of the second suction member 331, which can reduce the structural complexity of the second suction member 331 and the simplicity of the operation during operation. With such a design, the second suction member 331 can directly absorb the corner guard 60 and only needs to be translated and lifted without the need to rotate and adjust the posture.

[0041] That is to say, the first suction member 322 and the third suction member 333 of the present embodiment have two position states. When at the opening edge of the U-shaped frame 320, they are just above the flexible vibration plate 312 so as to grab the corner protector 60 on the flexible vibration plate 312. The other position state is to be at the side opposite to the opening edge. At this time, the first suction member 322 and the third suction member 333 are above the carrier 3321 of the second transmission module 332 so as to place the corner protector 60 on the carrier 3321 and transport the corner protector 60 to the side away from the vibration feeding assembly 31 through the transmission of the second transmission module 332. Figure 1 As shown on the right side, the second suction member 331 can easily suck the corner protector 60 on the carrier 3321 and transfer it to the corner protector placement and positioning mechanism 22 of the corner protector tape placement module 20 corresponding to the photovoltaic component 50.

[0042] As for the first suction member 322 and the third suction member 333, the two are consistent in structure and different from the structure of the second suction member 331. Since the positions of the two positioning grooves 33211 on the carrier 3321 on the second transmission module 332 of the second loading assembly 33 are fixed, that is, they correspond to the two corners on the right side of the photovoltaic assembly 50, when the corner guard 60 is transported from the left side to the right side of the second transmission module 332 by the carrier 3321 and is sucked by the second suction member 331 and transferred to the corresponding corner guard placement positioning mechanism 22 of the corner guard tape placement module 20, it is not necessary to adjust the position of the corner guard 60. Therefore, the third suction member 333 only needs to be lifted vertically and moved horizontally (including along the first direction and the second direction), and no rotation is required for position adjustment. However, when the first suction piece 322 and the third suction piece 333 suck the corner guard 60 from the flexible vibration disk 312, the position of the corner guard 60 is messy, that is, it does not completely correspond to the position of the two corners on the left side of the photovoltaic component 50 and the position of the two positioning grooves 33211 on the fixture, that is, the position of the two corners on the right side. Therefore, the position of the corner guard 60 needs to be adjusted. Therefore, in addition to the vertical lifting function and the horizontal movement function, the first suction piece 322 and the third suction piece 333 also have a rotation function around the vertical line. The purpose of the rotation is to adjust the position of the corner guard 60. That is to say, the third suction member 333 should also include the second vertical rotation driving member 3331 for driving the third suction member 333 to rotate around a vertical line, the third vertical displacement driving member 3332 for driving the third suction member 333 and the second vertical rotation driving member 3331 to rise and fall vertically as a whole, and the third horizontal displacement driving member for driving the third suction member 333, the second vertical rotation driving member 3331 and the third vertical displacement driving member 3332 to move horizontally, i.e., in the first direction as a whole. The second suction member 331 only includes the second suction member 331 and the second vertical displacement driving member 3311 for driving the second suction member 331 to rise and fall vertically, and the second horizontal displacement driving member 3312 for driving the second suction member 331 and the second vertical displacement driving member 3311 to move horizontally, i.e., in the first direction as a whole.

[0043] For the first suction member 322, the second suction member 331 and the third suction member 333, as shown in FIG. Figures 14 to 16As shown, each includes four suction cups arranged in an L shape, and each guard arm of the corner guard 60 corresponds to two suction cups. For the first horizontal displacement drive member 325, the second horizontal displacement drive member 3312 and the third horizontal displacement drive member, they are the structures of the existing conventional motor and belt combination, which are not described or limited here, and can be easily known and implemented by those skilled in the art. For the first vertical displacement drive member 324, the second vertical displacement drive member 3311, and the third vertical displacement drive member 3332, they can be selected as the existing conventional cylinders, which are not described or limited here, and can be easily known and implemented by those skilled in the art. For the first vertical rotation drive member 323 and the second vertical rotation drive member 3331, they can be selected as the existing conventional rotation motors, which are not described or limited here, and can be easily known and implemented by those skilled in the art.

[0044] It should be noted that the two first suction members 322 are independent, that is, one first suction member 322 corresponds to one first vertical rotation driving member 323, one first vertical displacement driving member 324 and one first horizontal displacement driving member 325. Similarly, the two third suction members 333 are independent, that is, one third suction member 333 corresponds to one second vertical rotation driving member 3331, one third vertical displacement driving member 3332 and one third horizontal displacement driving member. The two second suction members 331 are also independent, that is, each corresponds to one second vertical displacement driving member 3311 and one second horizontal displacement driving member 3312. Since the two first suction members 322 and the two third suction members 333 are all arranged on the first truss 321, in order to reduce the complexity of the structure and avoid interference during movement, in this embodiment, one of the first suction members 322 and the third suction member 333 are integrated together, and another first suction member 322 and another third suction member 333 are integrated together. The two third suction members 333 are arranged on the inner side of the two first suction members 322, that is, the two first suction members 322 are arranged on the inner side of the two first suction members 322. Fig.14 The front and rear ends are arranged. Figure 1 The first suction member 322 and the third suction member 333 at the front end are mounted on the same fixed base plate and are driven to move synchronously in the horizontal direction, i.e., in the first direction. Similarly, the first suction member 322 and the third suction member 333 at the rear end are mounted on the same fixed base plate (not shown) and are driven to move synchronously in the horizontal direction, i.e., in the first direction. In other words, the third horizontal displacement driving member and the first horizontal displacement driving member 325 are the same driving member, both of which are as shown in FIG. Fig.14 and Fig.16 The drive motor shown.

[0045] Compared with the prior art loading module 30 in the background art, the loading module 30 of this embodiment only needs to set a material bin 311 and a flexible vibration plate 312 on one side of the first transmission module 10, without setting two vibration loading plates. The two sets of loading components are used to respectively realize the transplanting and loading of the corner guards 60 at the four corners of the photovoltaic module 50, which is simpler in structure and occupies a smaller area. After testing, the equipment beat of this embodiment is about 16s, which is highly efficient.

[0046] Example 2

[0047] The difference from the first embodiment is that the number of the side tape attaching modules 40 in this embodiment is two. Figure 3 , the first adhesive tape 70 is respectively attached to the corner guards 60 of the four corners of the photovoltaic module 50, and a second adhesive tape 80 is respectively provided on the left side of the upper side and the right side of the lower side of the photovoltaic module 50, that is, a total of four first adhesive tapes and two second adhesive tapes 80, and the two second adhesive tapes 80 are arranged oppositely and staggered. The side tape attaching module 40 is consistent with the structure of embodiment 2, and will not be described in detail. The difference is that the number of the side tape attaching modules 40 is different. In this embodiment, the number of the side tape attaching modules 40 is two and they are arranged oppositely and staggered.

[0048] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, but do not constitute a limitation to the present invention.
