Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and particularly relates to an equipment for placing corner protectors and pasting tapes in the lamination process of photovoltaic modules. Background Art

[0002] A core process in the encapsulation process of photovoltaic modules is the lamination process. The solar cells are stacked inside double-layer glass, and all the air is exhausted to form a vacuum, protecting the solar cells from the external environment and increasing the service life of the photovoltaic modules. Configuring corner protectors at the four corners of the photovoltaic module can limit the amount of glue overflow between the two layers of glass during lamination, thereby achieving the purpose of limiting the lamination thickness of the module.

[0003] A Chinese invention patent with the publication number of "CN116190493A" discloses an automatic assembly equipment for corner protectors in the lamination process of photovoltaic modules, which can achieve synchronous placement of corner protectors around the photovoltaic module and pasting tapes to fix the corner protectors at the four corners of the photovoltaic module. The corner protector process disclosed in this patent document is: attaching a tape to each of the two protective arms of the corner protector, cutting the tape after lamination, and then pulling the corner protector backward. The existing photovoltaic modules corresponding to this corner protector installation process have edge tapes around the perimeter including two long sides and short sides before installing the corner protectors, and it is required that two sets of pasting devices are provided for each corner of the photovoltaic module corresponding to the equipment, and eight sets of pasting devices need to be provided in one equipment. In addition, for the corner protector installation process of the above technical solution, in order to facilitate subsequent removal of the corner protector, a groove needs to be opened on the outer side surfaces of the two protective arms of the corner protector to facilitate subsequent cutting of the tape. On the one hand, corner protectors with grooves need to be customized, and on the other hand, the cut tape may remain on the photovoltaic module and needs to be removed later, increasing costs and processes. Moreover, the above equipment cannot be applied to the installation of corner protectors of existing photovoltaic modules without side tapes pasted around the perimeter before installing the corner protectors. Therefore, it is necessary to provide a new equipment for placing corner protectors and pasting tapes in the lamination process of photovoltaic modules for the installation of corner protectors of existing photovoltaic modules without side tapes pasted around the perimeter before installing the corner protectors. Summary of the Invention

[0004] Aiming at at least one of the above existing technical problems, the purpose of the present invention is to provide an equipment for placing corner protectors and pasting tapes in the lamination process of photovoltaic modules for the installation of corner protectors of photovoltaic modules without side tapes pasted around the perimeter before installing the corner protectors, which can achieve the pasting of tapes on the corner protectors at the four top corners of the photovoltaic module along the diagonal direction of the corner protector and the pasting of side tapes on the sides of the photovoltaic module, and the tapes on the corner protectors can be removed at one time when the corner protectors are removed later.

A plurality of blowing and suction holes are formed in the suction surface of any one of the suction blocks; the two tape attaching mechanisms are oppositely and spacedly fixed to the upper and lower inner walls at the opening of the avoidance groove. Any one of the tape attaching mechanisms includes a first attaching roller that rotates about a horizontal line; the two elastic abutting members are relatively arranged on both sides in the thickness direction of the mounting substrate, and one end of any one of the elastic abutting members is movably connected to the mounting substrate and the other end is connected to the sliding plate; the sliding plate is in a state between the two first attaching rollers under the biasing force of the elastic abutting members in the initial state; any one of the elastic abutting members includes a abutting rod and an elastic member sleeved on the abutting rod; one end of the abutting rod is movably inserted through the end of the mounting substrate away from the avoidance groove, the other end is fixed to the sliding plate, and the axis of the abutting rod is parallel to the length direction of the avoidance groove.

The two first attaching rollers respectively roll on the outer surfaces of both ends of the first tape to fold the two ends of the first tape with the middle section already fixed outside the vertex angle of the corresponding corner guard along the diagonal direction of the corner guard from the outside to the inside and press and fix them on the upper and lower surfaces of the photovoltaic module.

Detailed implementation manners

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well - known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0034] Embodiment 1

[0035] A piece of equipment for placing and attaching corner guards with tape in the lamination process of a photovoltaic module provided in this embodiment, referring to Figures 1 to 19 , mainly includes a first transmission module 10, four corner - guard - tape - attaching modules 20, four side - tape - attaching modules 40, and a loading module 30.

[0036] Among them, the first transmission module 10 is along as Figure 1The photovoltaic module 50 is conveyed in the front-back direction shown (it should be noted that the front and back here are not the exact front and the exact back as shown in Figure 1 , but the side of the device facing the reader is the front, and the side facing away from the reader is the back), so as to facilitate the input and output of the photovoltaic module 50. The first transmission module 10 is used for the conveyance of the photovoltaic module 50 (including the input of the photovoltaic module 50 to be laminated and the output of the laminated photovoltaic module 50) and positioning during the placement of the corner protector 60 and the taping. For the first transmission module 10, its structure and working principle will not be described. It is a conventional conveyance module for photovoltaic modules 50 in the prior art, not an innovation point of the present invention, and it is easily known and implemented by those skilled in the art. For the sake of easy description and distinction, in this embodiment, the conveyance direction of the first transmission module 10 is described as the first direction, and the left-right direction as shown in Figure 1 is the second direction. The first direction and the second direction are perpendicular in the same horizontal plane, and the vertical direction is perpendicular to the first direction and the second direction in space. The first direction, the second direction, and the vertical direction are perpendicular to each other pairwise in space, constituting the three-axis directions of a triangular coordinate system. For the corner protector 60, its structure will not be described and limited, and reference can be made to the description in the prior art in the background technology, which is not an innovation point of the present invention.

[0037] In this embodiment, the four corner protector and taping modules 20 are respectively arranged outside the four corners of the first transmission module 10 and can respectively move closer to or away from the corresponding corners of the photovoltaic module 50 to be laminated on the middle first transmission module 10 to complete the installation and fixation of the corner protector 60 and the pasting and fixation of the first tape 70. Compared with the prior art in the background technology, only one module is required for each corner protector 60 to complete the installation and taping fixation of the corner protector 60, with fewer structures, lower costs, and simpler subsequent tape disassembly. Specifically, for each corner protector and taping module 20, as shown in Figure 4 , Figure 8 , Figure 9 and Figure 19 , it mainly includes three parts: a fixed-length tape cutting component 21, a corner protector placement and positioning mechanism 22, and a tape attachment mechanism 23. It should be noted that as shown in Figure 9As shown, the fixed-length tape cutting assembly 21, the corner protector placement and positioning mechanism 22, and the tape attachment mechanism 23 are installed on the same base (not shown) and are jointly driven to move towards or away from the corner of the corresponding photovoltaic module 50 of the corner protector and tape attachment module 20. The corner protector placement and positioning mechanism 22 is closer to the photovoltaic module 50. When approaching, the corner protector placement and positioning mechanism 22 first contacts the photovoltaic module 50 and presses the fixed corner protector 60 against the outside of the corner of the photovoltaic module 50. Then, the tape attachment mechanism 23 moves along the diagonal of the base or the diagonal of the corner protector 60 towards or away from the corner of the photovoltaic module 50 relative to the fixed-length tape cutting assembly 21 and the corner protector placement and positioning mechanism 22 to paste and fix the corner protector 60 to the corner of the photovoltaic module 50 with the first tape 70. More specifically, the corner protector placement and positioning mechanism 22 is arranged close to the photovoltaic module 50 on the first transfer module 10. It is used to fix the corner protector 60 to be installed and press the corner protector 60 against the outside of the corresponding corner of the photovoltaic module 50 to position the corner protector 60 at the corresponding corner of the photovoltaic module 50 before taping. The fixed-length tape cutting assembly 21 is arranged on the side of the corner protector placement and positioning mechanism 22 away from the photovoltaic module 50, cuts a section of the first tape 70 for pasting and fixing the corner protector 60 to the corresponding corner of the photovoltaic module 50, and folds one end of the section of the first tape 70 to form a first folding portion 71. The tape attachment mechanism 23 is rotatably arranged between the fixed-length tape cutting assembly 21 and the corner protector 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 after the corner protector 60 is fixed to the corner of the photovoltaic module 50, adsorb and fix the first tape 70, turn it over, and paste the cut first tape 70 on the corner protector 60 and the photovoltaic module 50. Specifically, press the middle section of the first tape 70 against the top corner of the corner protector 60, and use the top corner of the corner protector 60 as the folding starting point to fold the two ends of the first tape 70 in the same direction and respectively paste and fix them on the upper and lower surfaces of the photovoltaic module 50. That is, the first tape 70 is pasted along the diagonal of the corner protector 60.

[0038] As Figure 4 shown, the fixed-length tape cutting assembly 21 mainly includes five parts: a first tape reel holder 211, an upper clamping mechanism 214, a folding mechanism 212, a lower clamping mechanism 215, and a tape cutting mechanism 213. Specifically, the first tape reel holder 211 is a conventional disk-shaped structural member that can rotate around a horizontal line, and the first tape roll is installed on the first tape reel holder 211. The first tape reel holder 211 of this embodiment is arranged at the top and releases the first tape 70 downward. The upper clamping mechanism 214, the folding mechanism 212, the lower clamping mechanism 215, and the tape cutting mechanism 213 are all arranged below the first tape reel holder 211. The folding mechanism 212 is arranged on the tape feeding path of the first tape reel holder 211, specifically as Figure 8Below the discharge end of the first tape reel holder 211 shown. That is, after the first tape 70 is sent out from the first tape reel holder 211, it is pulled vertically downward. The purpose of the folding mechanism 212 is to fold the free end of a section of the first tape 70 to be cut, that is, the lower end shown in the figure, towards the end to be cut, that is, as shown in the figure. Figure 8 shown, towards the end to be cut with the lower end facing it, that is, as shown in the figure. Figure 8 shown, fold it upward. The lower clamping mechanism 215 is vertically liftably arranged below the first tape reel holder 211. The lower clamping mechanism 215 is used to clamp the free end of the folded first tape 70 to form the first folding part 71, and at the same time, when descending downward, pull the first tape 70 downward by a certain length so that the end to be cut of the first tape 70 is exactly on the same horizontal plane as the tape cutting mechanism 213. The upper clamping mechanism 214 is arranged between the first tape reel holder 211 and the folding mechanism 212 to clamp the upper end of the end to be cut of the first 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 it can be driven to translate horizontally in the direction of approaching or departing from the first tape 70, and is used to perform a translational movement in the direction of approaching the first tape 70 after the first tape 70 is stretched downward by the lower clamping mechanism 215 to a preset length to cut the end to be cut of the first tape 70.

[0039] Specifically, as shown in the figure. Figure 4 and Figure 6 shown, the folding mechanism 212 includes a first driving member 2121 and a first clamping member 2122 and a second clamping member 2123 that move relative to each other under the drive of the first driving member 2121. The first clamping member 2122 and the second clamping member 2123 have an open state of separation and a closed state of approaching. In the open state, the free end of the first tape 70 passes between the first clamping member 2122 and the second clamping member 2123. For the convenience of description and distinction, the clamping end of the first clamping member 2122, that is, the front end shown in the figure, is the first clamping section (not marked), and the clamping end of the second clamping member 2123, that is, the front end shown in the figure, is implemented as the second clamping section (not marked). In the closed state, the first clamping section and the second clamping section clamp the two sides of the free end of the first tape 70, that is, as shown in the figure. Figure 6 shown, the front end is the first clamping section (not marked), and the clamping end of the second clamping member 2123, that is, as shown in the figure. Figure 6 shown, the front end is implemented as the second clamping section (not marked). In the closed state, the first clamping section and the second clamping section clamp the two sides of the free end of the first tape 70, that is, as shown in the figure. Figure 6On the front and back sides as shown, and the two are offset in the vertical direction, that is, one is above and the other is below, so that the free end of the first tape 70 can be folded towards the side of its to-be-cut end. Exemplarily, in this embodiment, the first clamping section is above and the second clamping section is below. Thus, the free end at the lower end of the first tape 70 is folded under the clamping force of the first clamping section and the second clamping section, specifically, folded upwards. Preferably, the first clamping section and the second clamping section are cylindrical structures, similar to chopsticks. For the first driving member 2121, it can be selected as a conventional existing cylinder. It should be noted that in this embodiment, the folding mechanism 212 can perform a translational movement on the horizontal plane, specifically, horizontally approach or horizontally move away from the first tape 70 between the upper clamping mechanism 214 and the lower clamping mechanism 215. The horizontal movement away is to prevent interference with the movement of the lower clamping mechanism 215 and the first tape 70 during the process of the lower clamping mechanism 215 clamping the folded free end to form the first folding portion 71 and pulling it down by a preset length. In this embodiment, as Figure 6 shown, both the folding mechanism 212 and the tape cutting mechanism 213 are arranged on the rear side shown in the figure, and the folding mechanism 212 is located above the tape cutting mechanism 213.

[0040] For the upper clamping mechanism 214, as Figure 4 and Figure 6 shown, it includes a fixed pressing plate 2141 and a movable pressing plate 2142 that are arranged oppositely along the two surfaces of the first tape 70, that is, the left and right surfaces as Figure 8 shown, and a second driving member 2143 that drives the movable pressing plate 2142 to move closer to or away from the fixed pressing plate 2141, that is, to perform a left and right translation as Figure 8 shown. In the figure, the fixed pressing plate 2141 and the movable pressing plate 2142 are arranged at intervals left and right relatively, and the free end of the first tape 70 passes downward through the interval between the two. Preferably, a recess is formed on the side surface of the fixed pressing plate 2141 facing the movable pressing plate 2142, which is recessed away from the movable pressing plate 2142, that is, Figure 8 shown as recessed to the right and extending along the tape feeding path direction, that is, Figure 8The downwardly extending and penetrating guide groove (not shown) is provided. Correspondingly, at one end of the movable pressing plate 2142 facing the fixed pressing plate 2141, a pressing convex portion (not shown) that protrudes and extends toward the fixed pressing plate 2141 and matches the guide groove is formed. The pressing convex portion is embedded in the guide groove to clamp and fix the upper end of the to-be-cut end of the first tape 70. For the second driving member 2143, similarly, a conventional existing air cylinder can be selected. Preferably, a plurality of first adsorption holes 21411 communicating with the guide groove are formed on the fixed pressing plate 2141. The purpose of the first adsorption holes 21411 is to adsorb and fix the first tape 70 on the fixed pressing plate 2141 when the movable pressing plate 2142 is separated from the first tape 70. Specifically, when the lower clamping mechanism 215 clamps the first folding portion 71 and pulls it downward, the first tape 70 is adsorbed and attached to the guide groove on the fixed pressing plate 2141 by the first adsorption holes 21411, which not only plays a guiding role but also prevents the first tape 70 from slipping out of the guide groove of the fixed pressing plate 2141, which is not conducive to the subsequent pressing of the first tape 70 by the movable pressing plate 2142.

[0041] For the lower clamping mechanism 215, as Figure 5 shown, it mainly includes a clamping assembly 2151 and a third driving member 2152. Among them, the clamping assembly 2151 in this embodiment can be selected as a conventional existing pneumatic chuck mechanism. Specifically, it includes as 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.

[0042] For the tape cutting mechanism 213, if Figure 6As shown, this embodiment exemplarily shows a conventional pneumatic scissor mechanism. Specifically, it includes a pneumatic scissor 2131 that can be opened and closed, and a fourth driving member 2132 that drives the pneumatic scissor 2131 to move in a direction close to or away from the first tape 70, that is, to move horizontally in the front-back direction as shown in Figure 8 shown. For the fourth driving member 2132, it can be an existing conventional cylinder.

[0043] For the tape attaching mechanism 23, in this embodiment, the tape attaching mechanism 23 is installed together with the fixed-length tape cutting assembly 21 and can move horizontally in a direction close to or away from the photovoltaic module 50 synchronously, and the tape attaching mechanism 23 is arranged on the side of the lower clamping mechanism 215 close to the photovoltaic module 50, that is, on the right side as shown in Figure 8 shown. Moreover, the lower clamping mechanism 215 can move horizontally in a direction close to or away from the tape attaching mechanism 23, that is, the lower clamping mechanism 215 can move horizontally in the left-right direction as shown in Figure 8 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 translates towards 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 cuts the to-be-cut end of the first tape 70. It should be noted that when the lower clamping mechanism 215 moves in a direction close to or away from the tape attaching mechanism 23, the upper clamping mechanism 214, the folding mechanism 212, the tape cutting mechanism 213, and the first tape reel holder 211 move together. That is to say, the upper clamping mechanism 214, the folding mechanism 212, the tape cutting mechanism 213, the first tape reel holder 211, and the lower clamping mechanism 215 are installed on the same fixing plate (exemplarily, the fixing plate on the front side as shown in Figure 4 shown, not marked), while the tape attaching mechanism 23 is installed on another fixing plate (exemplarily, the fixing plate on the rear side as shown in Figure 4 shown, not marked), and the two fixing plates are slidably connected. Specifically, as shown in Figure 7 shown, the tape attaching mechanism 23 includes an attaching assembly 231 and a horizontal rotation driving member 232. The horizontal rotation driving member 232 can rotate around a horizontal axis extending in the front-back direction as shown in Figure 7 shown to drive the attaching assembly 231 to rotate synchronously so that its attaching end faces the lower clamping mechanism 215 on the left side as shown in Figure 4 shown or faces the photovoltaic module 50 on the right side as shown in Figure 4 shown (not shown in Figure 1 ). For the horizontal rotation driving member 232, it is an existing conventional rotating motor.

[0044] For the attaching assembly 231, as shown in Figure 7As shown, it mainly includes an installation substrate 2311, two adsorption blocks 2312, two tape - sticking mechanisms, two elastic abutting components 2314 and a sliding plate 2315. Among them, the installation substrate 2311 is connected to the horizontal rotation driving part 232 and has a horizontally extending avoidance groove 23111 in the middle, that is, extending from right to left as shown in Figure 7 shown. The two adsorption blocks 2312 are respectively fixed at the upper and lower ends of the openings of the corresponding avoidance grooves 23111 of the installation substrate 2311, and the outer end faces of the two adsorption blocks 2312, that is, the left end faces as shown in Figure 7 shown, are implemented as adsorption surfaces. A number of blowing and suction holes 23121 are opened on the adsorption surface of any one of the adsorption blocks 2312, aiming to provide suction when the sticking assembly 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 stuck and fixed on the upper and lower surfaces of the corner guard 60 and the photovoltaic module 50. Preferably, the two sticking blocks can move vertically to adjust the distance between them, aiming to match first tapes 70 of different lengths. The two tape - sticking mechanisms are oppositely and spacedly fixed on the upper and lower inner walls at the opening of the avoidance groove 23111. Any one of the tape - sticking mechanisms includes a mounting block (not labeled) horizontally fixed at the opening of the avoidance groove 23111 and a first sticking roller 2313 mounted at the outer end of the mounting block, that is, the right end as shown in Figure 7 shown, and can rotate relative to the mounting block around a horizontal line in the front - to - back direction as shown in Figure 7 shown. The two elastic abutting components 2314 are oppositely arranged on both sides in the thickness direction of the installation substrate 2311, that is, the front and back sides as shown in Figure 7 shown, and one end of any one of the elastic abutting components 2314, that is, the left end as shown in Figure 7 shown, is movably connected to the left end of the installation substrate 2311, and the other end, that is, as shown in 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 biasing member 2314 and is located between the two first attaching rollers 2313 of the two tape attaching mechanisms. When the horizontal rotation driving member 232 drives the adsorption surface of the attaching assembly 231 to face the corresponding corner of the photovoltaic module 50 to which the corner guard 60 is to be installed and the tape attaching mechanism 23 is driven to move close to the corner guard 60 at the corresponding corner of the photovoltaic module 50, the middle section of the first tape 70 adsorbed by the two adsorption blocks 2312 is pressed and fixed at the top corner of the corresponding corner guard 60 by the two first attaching rollers 2313, and the sliding plate 2315 is pressed by the corresponding corner guard 60 and retracts into the avoidance groove 23111. The corner guard 60 enters the avoidance groove 23111, so that the two ends of the first tape 70 are flattened on the upper and lower surfaces of the corner guard 60 under the action of the inner wall of the avoidance groove 23111, and the two ends of the first tape 70 extend horizontally inward along the diagonal line of the corner guard 60 towards the inside of the photovoltaic module 50. During this process, the two first attaching rollers 2313 of the two tape attaching mechanisms respectively roll and press against the outer surfaces of the two ends of the first tape 70 to turn the two ends of the first tape 70, whose middle section has been fixed at the top corner of the corner guard 60, from the outside to the inside and flatten and bond them on the upper and lower surfaces of the photovoltaic module 50. For the elastic biasing member 2314, as Figure 7 shown, it includes a cylindrical biasing rod 23141 extending horizontally in the left-right direction as shown in Figure 7 and an elastic member 23142 (exemplarily a tubular straight spring) sleeved on the outer periphery of the biasing rod 23141. The left end of the biasing rod 23141 is movably inserted through the left end of the mounting substrate 2311, that is, the end opposite to the avoidance groove 23111. The right end of the biasing rod 23141 is fixed to the inner end, that is, the left end, of the sliding plate 2315, and the axis of the biasing rod 23141 is parallel to the extending direction, that is, the length direction, of the avoidance groove 23111. The elastic member 23142 applies a biasing force to the sliding plate 2315 to make the sliding plate 2315 tend to the notch of the avoidance groove 23111 and be located between the two first attaching rollers 2313.

[0045] For the corner guard placement and positioning mechanism 22, it can be driven to move closer to or away from the corresponding corner of the photovoltaic module 50 and press the corner guard 60 against the corresponding corner of the photovoltaic module 50 when moving closer. It should be noted that the corner guard placement and positioning mechanism 22, the fixed-length tape cutting assembly 21 and the tape attaching mechanism 23 in this embodiment are arranged on the same bottom plate and can be driven to move synchronously closer to or away from the corresponding corner of the photovoltaic module 50. Its specific structure is not described and defined in detail and can refer to the prior art mentioned in the background art. An exemplary one is as Figure 9 shown. The corner guard placement and positioning mechanism 22 in this embodiment includes two opposite and spaced (that is, as Figure 9The front-to-back relative spacing setting shown is for the purpose of avoiding interference with the side edges of the photovoltaic module 50). There are provided corner guard fixing platforms 221 and pressing blocks 222 that can be lifted vertically and rotated around a vertical line and are respectively provided on any one of the corner guard fixing platforms 221. On the upper surface of any one of the corner guard fixing platforms 221 and on one side close to the other corner guard fixing platform 221, there is a downwardly recessed fixing groove 2211 that matches one end of one of the guard arms of the corner guard 60 that is far from the vertex angle 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 respectively press against the upper surfaces of the two guard arms of the corner guard 60. Inside any one of the corner guard fixing platforms 221, there is a rotary lifting driving member (not shown, which can be an existing conventional motor-screw mechanism for example) 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 synchronously lift vertically. The lifting driving mechanism (not labeled) of the corner guard fixing platform 221 is not described and limited, and it is an existing conventional lifting cylinder. Optionally, on the fixed base (not labeled) of the corner guard fixing platform 221, there is also provided a corner support positioning platform 90 that supports the bottom surface of the photovoltaic module 50 (not specifically described, refer to the positioning mechanism described in the prior art in the background art). The corner support positioning platform 90 and the two corner guard fixing platforms 221 are arranged relatively, that is, as Figure 9 shown in the left-to-right relative setting, and the corner guard fixing platform 221 is close to the tape attaching mechanism 23, that is, as Figure 9 shown on the left side, and the corner support positioning platform 90 is far from the tape attaching mechanism 23, that is, as Figure 9 shown on the right side, which is the side close to the photovoltaic module 50.

[0046] The corner guard tape attaching device of this embodiment is for photovoltaic modules without edge tapes before corner guard installation. In order to improve the lamination effect and reduce the occurrence of glue leakage, it is necessary to paste C-shaped second tapes 80 on the two long sides of the photovoltaic module 50. Specifically, refer to Figure 2 , first tapes 70 are respectively pasted at the four corners of the corner guards 60 of the photovoltaic module 50, and a group of long sides of the photovoltaic module 50, that is, as Figure 2 shown, there is one second tape 80 at each of the left and right ends of the upper side edge and the left and right ends of the lower side edge. There are a total of four first tapes 70 and four second tapes 80. That is, there is also a second tape 80 at a preset distance (not described and limited, and those skilled in the art can choose and design according to the actual situation) from any one corner guard 60 on each long side. The second tape 80 is attached by the side tape attaching module 40. Correspondingly, each second tape 80 corresponds to one side tape attaching module 40. That is, a group of corresponding sides at the two ends of the photovoltaic module 50 in the corresponding first direction are specifically two long sides, that is, as Figure 2On the outer sides of the left and right ends of any one of the upper and lower sides shown, a side tape attaching module 40 is provided on each side, and the side tape attaching module 40 is located inside the corner protector tape attaching module 20. This can further reduce the problem of glue leakage during the lamination process of the photovoltaic module 50 and improve the lamination quality of the photovoltaic module 50.

[0047] The side tape attaching module 40 of this embodiment, as Figures 10 to 13 shown, mainly includes a second tape reel holder 41, a plurality of guide wheels 42, a pressing head mechanism 44, a lower attaching mechanism 43, an upper attaching mechanism 45, a winding mechanism 48, a pressing rod mechanism 47, and a tape cutting mechanism 46. Among them, the second tape 80 is wound on the second tape reel holder 41, and the second tape reel holder 41 is arranged at the lower right as Figure 10 shown. The lower attaching mechanism 43, the pressing head mechanism 44, the second tape reel holder 41, and some of the guide wheels 42 are synchronously lifted and lowered and horizontally moved along the first direction, that is, the left-right direction as Figure 10 shown. A plurality of guide wheels 42 are arranged on the tape feeding path of the second tape reel holder 41 for tensioning and guiding the second tape 80. Exemplarily, as Figure 10 and Figure 11 shown, there are four guide wheels 42, all arranged on the left side of the second tape reel holder 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 the height position is located on the left side of the lowest position and the other guide wheels 42.

[0048] As Figure 10 shown, the lower attaching mechanism 43 is arranged 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 tape feeding path, and is used to attach the second tape 80 to the lower surface of the photovoltaic module 50. Specifically, as Figure 12 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. The second tape 80 passes through the guide plate 431 with the glue surface facing up. In the middle of the upper surface of the guide plate 431, there is a guide convex part 4311 protruding upward and extending from the bottom end to the top end of the guide plate 431. The width of the guide convex part 4311 is the same as the width of the second tape 80, and at the top end of the guide plate 431, there is a guide inclined surface 4312 extending obliquely downward. Blow holes 4313 for blowing air to the second tape 80 to make the second tape 80 horizontal are opened on the guide inclined surface 4312, that is, at the position where the guide plate 431 is close to the second attaching roller 432. The pressing head mechanism 44 is arranged on the side of the lower attaching mechanism 43, specifically on the right side as Figure 10 shown, and is located above the right of the guide wheel 42 at the highest position, that is, the guide wheel 42 at the end of the tape feeding path. For the pressing head mechanism 44, as Figure 10As shown, it includes a pressing drive member 441 arranged obliquely downward and a pressing head 442 provided at the lower end of the pressing drive member 441 (the end face is a sphere). Before the lower attaching mechanism 43 attaches the tape, the pressing head 442 is driven by the pressing drive member 441 to press against the second tape 80 on the guiding wheel 42 at the very end of the tape feeding path, that is, the guiding wheel 42 at the highest position in the figure, and is released when the lower attaching mechanism 43 attaches the tape. For the pressing drive member 441, it can be an existing conventional cylinder.

[0049] It should be noted that in this embodiment, the lower attaching mechanism 43, the pressing head mechanism 44, the second tape reel holder 41, and some of the guiding wheels 42 (specifically, three guiding wheels 42 at the lowest, highest, and second highest positions in terms of height) are installed on the same fixed plate (not labeled) and can be lifted and lowered synchronously in the vertical direction and horizontally moved in the first direction, that is, the left - right direction as shown in Figure 10 the figure. In addition, in this embodiment, the tape cutting mechanism 46, the pressing rod mechanism 47, the winding mechanism 48, and the upper attaching mechanism 45 are installed on the same fixed plate (not labeled) and can be lifted and lowered synchronously in the vertical direction. And preferably, the two fixed plates can move relative to each other to adjust the distance between the upper attaching mechanism 45 and the lower attaching mechanism 43. It should be noted that this adjustment is carried out before the equipment starts operating, and adjustment between the two is not allowed during the operation process.

[0050] Specifically, as shown in Figure 10 the figure, the tape cutting mechanism 46 is close to the lower attaching mechanism 43, specifically arranged on the left side of the lower attaching mechanism 43, and the tape cutting mechanism 46 can be lifted and lowered in the vertical direction. Here, this lifting and lowering is different from the synchronous lifting and lowering of the tape cutting mechanism 46, the pressing rod mechanism 47, the winding mechanism 48, and the upper attaching mechanism 45. Here, the lifting and lowering is with respect to the tape cutting mechanism 46 relative to other mechanisms, that is, the pressing rod mechanism 47, the winding mechanism 48, and the upper attaching mechanism 45. After the lower attaching mechanism 43 attaches the second tape 80 on the lower surface of the photovoltaic module 50 and the second tape 80 is pulled out a predetermined length in the first direction (it should be noted that the pulling out of the second tape 80 here is achieved through the horizontal movement of the entire side - edge tape attaching module 40), the tape cutting mechanism 46 cuts the end of the second tape 80 to be cut.

[0051] The upper attaching mechanism 45 is arranged on the side of the tape cutting mechanism 46 away from the lower attaching mechanism 43, that is, on the left side as shown in Figure 10 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 the first direction in a 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 in a direction away from the tape cutting mechanism 46 during the tape - attaching process, that is, as shown in Figure 10Move in the left direction shown. As Figure 13 As shown, the upper attaching mechanism 45 includes a mounting base 451 and a third attaching roller 452 disposed on one 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. 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 are formed on the mounting base 451.

[0052] As Figure 10 and Figure 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 flipped about a horizontal line in the front-back direction (this horizontal line is parallel to the axis of the third attaching roller 452) as shown in Figure 13 to fold the cut end of the second tape 80 to form a second folding portion 81. Among them, the second adsorption holes 453 are arranged on the side close to the winding mechanism 48. The cut end of the second tape 80 after being cut is placed above the winding mechanism 48. During the flipping process of the winding mechanism 48, the cut end, that is, the right end as shown in Figure 13 is flipped to the other end, that is, the left end as shown in Figure 13 As shown.

[0053] For the pressing rod mechanism 47, the side of the upper attaching mechanism 45 where it is disposed at the initial position is specifically the rear side as shown in Figure 10 and it can be vertically lifted and horizontally moved closer to or away from the upper part of the upper attaching mechanism 45 at the initial position, that is, moved forward as shown in Figure 10 As shown. Similarly, it should be noted that the lifting here is relative to other mechanisms, that is, the tape cutting mechanism 46 and the lower attaching mechanism 43. The pressing 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 the second tape 80 and before the winding mechanism 48 flips to form the second folding portion 81, and releases the second tape 80 after the second folding portion 81 is formed. The second adsorption holes 453 break the vacuum to release the second tape 80 after the pressing rod mechanism 47 releases the second tape 80. The upper attaching mechanism 45 is driven to horizontally move relative to the tape cutting mechanism 46 and the pressing rod mechanism 47 in the first direction so that the third attaching roller 452 presses on the second tape 80 to complete the pasting of the second tape 80 on the upper surface of the photovoltaic module 50. Specifically, as shown in Figure 11As shown, the pressing rod mechanism 47 includes a vertical cylinder 471 that moves vertically up and down, a horizontal cylinder 472 that moves horizontally in and out, and a rod body 473 that is horizontally fixed on the side of the horizontal cylinder 472 facing the attaching mechanism 45. Before the cutting of the end of the second tape 80 to be cut, the rod body 473 is retracted. After the second tape 80 is cut and before the winding mechanism 48 winds, the rod body 473 is driven by the horizontal cylinder 472 to extend and is located above the second tape 80, and then descends through the vertical cylinder 471 so that the rod body 473 presses on the second tape 80.

[0054] For the convenience of description and distinction, the horizontal driving member that drives the lower attaching mechanism 43, the pressing head mechanism 44, the second tape reel holder 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 horizontally is described as the second horizontal driving member 411, the lifting driving member that drives the lower attaching mechanism 43, the pressing head mechanism 44, the second tape reel holder 41, and the guide wheel 42 to move up and down 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 pressing rod mechanism 47 to move up and down 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 in this embodiment can all be selected as cylinders.

[0055] For the winding mechanism 48, as Figure 13 shown, it includes a winding motor 481 fixed on the mounting base 451 and whose winding shaft 4811 can rotate around a horizontal line, that is, a horizontal line extending front and back as Figure 10 shown, and an L-shaped winding block 482 connected to the winding shaft 4811. The winding motor 481 drives the side of the winding block 482 facing the mounting base 451, that is, as Figure 13 shown, to flip leftward to fold the cut end of the second tape 80 placed on it to the left to form a second folding portion 81. The axis of the winding shaft 4811 of the winding motor 481 is parallel to the axis of the third attaching roller 452. Specifically, a relief groove (not labeled) that extends downward and leftward is formed at the right end of the mounting base 451. The winding shaft 4811 is rotatably arranged on the relief groove, and the winding block 482 lies flat, that is, its 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 flip.

[0056] For the tape cutting mechanism 46, it can be selected as an existing conventional vertically retractable cutter, and its specific structure is not described and limited. Those skilled in the art can easily understand and implement it.

[0057] As Figure 19As shown, a side tape attaching module 40 and a corner protector tape placing module 20 of this embodiment are installed on the same fixed base (not labeled). The fixed base can move horizontally in the first direction and the second direction perpendicular to the first direction so that the corner protector tape placing module 20 and the side tape attaching module 40 move closer to or farther away from the corner position of the photovoltaic module 50. Among them, the side tape attaching module 40 is arranged on one side of the fixed base close to the photovoltaic module 50, while the corner protector tape placing module 20 is arranged along the diagonal of the fixed base and can move horizontally closer to or farther 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 corresponding to the corner protector 60 to realize the pasting and fixing of the first tape 70 on the corner protector 60.

[0058] The loading module 30 of this embodiment includes three parts, as Figure 1 and Figures 14 to 18 shown. One part is a vibrating loading component 31 for feeding the corner protector 60, one part is a first loading component 32 for picking up and transplanting the corner protectors 60 corresponding to the two corners of one side of the photovoltaic module 50 (exemplarily the side close to the vibrating loading component 31 in this embodiment), and another part is a second loading component 33 for picking up and transplanting the corner protectors 60 corresponding to the two corners of the other side (exemplarily the side far from the vibrating loading component 31 in this embodiment). Among them, the vibrating loading component 31 includes a bin 311 for loading the corner protector 60 arranged on the outer side ( Figure 1 exemplarily the left side in [ID]) of one side of the first transmission module 10, that is, far from the first transmission module 10, a flexible vibrating disk 312 arranged on the inner side, that is, close to the first transmission module 10, and located below the discharge port of the bin 311 and below the first loading component 32, and a camera device arranged above the flexible vibrating disk 312 ( Figure 1(not shown in the figure). For the flexible vibrating disk 312, its structure and working principle will not be described and limited herein. It is a conventional flexible vibrating device in the art, and those skilled in the art can easily understand and implement it. Its purpose is to vibrate the corner guard 60 sent out from the discharge port of the silo 311 to a horizontal state, so as to facilitate the subsequent first feeding component 32 and second feeding component 33 to suck the corner guard 60 for feeding. The imaging device is used to capture the actual pose of the corner guard 60 on the flexible vibrating disk 312, that is, the orientation of the opening of the corner guard 60. In order to make the sucked corner guard 60 correspond to the corresponding corner of the photovoltaic module 50, after the first feeding component 32 and the second feeding component 33 suck the corner guard 60 from the flexible vibrating disk 312, the pose of the corner guard 60 needs to be adjusted so that the pose of the corner guard 60 matches the corresponding corner of the photovoltaic module 50. In this embodiment, the imaging device is communicatively connected to both the first feeding component 32 and the second feeding component 33. After the first feeding component 32 and the second feeding component 33 suck the corner guard 60, they will compare the actual pose of the corner guard 60 during suction with the pose of the corresponding corner of the photovoltaic module 50. If they are the same, the first feeding component 32 and the second feeding component 33 do not need to adjust the pose of the corner guard 60; if they are different, the pose of the corner guard 60 needs to be adjusted. Exemplarily, the imaging device is a conventional industrial camera in the art, and its specific structure and working principle will not be described and limited. It is prior art and not an innovation point of the present invention.

[0059] For the first feeding component 32 and the second feeding component 33, they are different in structure and installation position. Specifically, as Figure 14 and Figure 15 shown, the first feeding component 32 includes a first truss 321 and two first suction members 322 slidably disposed on the first truss 321. For the first truss 321, it extends along the first direction, and a U-shaped frame 320 is further provided at the bottom of the first truss 321. The U-shaped frame 320 is disposed above the flexible vibrating disk 312 and its open side faces one side of the flexible vibrating disk 312. The first truss 321 is disposed on the open side of the U-shaped frame 320 and forms a square frame body with the U-shaped frame 320, and 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 realize one side of the photovoltaic module 50, that is, as Figure 1 shown, the side close to the vibrating feeding component 31, that is, as Figure 1The transplanting and loading of the corner guards 60 at the front and rear ends on the left side shown. In this embodiment, the number of the first suction members 322 is two. The two first suction members 322 are arranged on the first truss 321 at relative intervals and are independently driven to move freely relative to the first truss 321 in the first direction. Any one of the first suction members 322 can be driven to lift vertically and rotate around the vertical line. That is to say, the first loading assembly 32 is actually composed of the first truss 321, two first suction members 322, two first horizontal displacement driving members 325, two first vertical displacement driving members 324 and two first vertical rotation driving members 323. Any one of the first vertical rotation driving members 323 drives a first suction member 322 to rotate around the vertical line. Any one of the first vertical displacement driving members 324 drives a first suction member 322 and the first vertical rotation driving member 323 as a whole to lift vertically. Any one of the first horizontal displacement driving members 325 drives a first suction member 322, a first vertical rotation driving member 323 and a first vertical displacement driving member 324 as a whole to move horizontally, that is, in the first direction.

[0060] As Figure 16 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 in parallel with the first truss 321, that is, it extends in the first direction. However, the second truss 330 is arranged at the right end of the equipment as Figure 1 shown. The two second suction members 331 are arranged on the second truss 330 so as to be driven to slide in the first direction. The second transmission module 332 is arranged across the first transmission module 10 and the photovoltaic module 50 thereon, that is, the second transmission module 332 extends in the second direction. The two third suction members 333 are arranged on the first truss 321 in the same way as the two first suction members 322. In this embodiment, the two third suction members 333 are mainly used to suck the corner guard 60 from the flexible vibrating disk 312, adjust the position and posture of the corner guard 60, and then transplant it onto the carrier 3321 on the second transmission module 332. The carrier 3321 loaded with the corner guard 60 is conveyed from the left side as Figure 1 or Figure 17 shown, that is, the side close to the vibrating loading assembly 31, specifically the flexible vibrating disk 312, to the right side, that is, the side far from the flexible vibrating disk 312. Then, the empty carrier 3321 is conveyed from the right side and reset to the left side. The two second suction members 331 are used to suck the corner guard 60 on the carrier 3321 and transplant it to the corresponding end when the carrier 3321 is conveyed to the right side of the second transmission module 332, that is, as Figure 1On the corner placement and positioning mechanisms 22 of the two corner guard tape application modules 20 at the front and rear ends on the right side of the device. For the second transfer module 332, its structure is the same as that of the first transfer module 10, that is, both are rail or conveyor belt type transfer structures. In this embodiment, an exemplary rail transfer structure is used, and the carrier 3321 is slidably arranged on the rail. In some preferred embodiments, the number of carriers 3321 is two, and the two carriers 3321 are arranged at intervals relative to each other. During operation, one carrier 3321 is located on the left side of the second transfer module 332, that is, at the pick-and-place position of the third pick-up member 333 close to the flexible vibrating disk 312, and the other carrier 3321 is located on the right side of the second transfer module 332, that is, at the pick-and-place position of the second pick-up member 331 far from the vibrating feeding assembly 31. This can greatly improve efficiency.

[0061] For the carrier 3321, as Figure 17 and Figure 18 shown, any carrier 3321 is a flat structural member, on which there are two relatively spaced and downwardly recessed and extending positioning grooves 33211. The shape and size of the positioning grooves 33211 are consistent with the shape and size of the corner guard 60, and the pose of the positioning grooves 33211 corresponds to the pose of the corners at the front and rear ends on the right side of the photovoltaic module 50 as shown in Figure 1 This can reduce the structural complexity of the second pick-up member 331 and the simplicity of the operation during work. With such a design, the second pick-up member 331 can directly pick up the corner guard 60 and only needs to be translated and lifted, without the need to rotate and adjust the pose.

[0062] That is to say, the first pick-up member 322 and the third pick-up member 333 in this embodiment have two position states. When at the open side of the U-shaped frame 320, they are exactly above the flexible vibrating disk 312 to facilitate grasping the corner guard 60 on the flexible vibrating disk 312; the other position state is at the side opposite to the open side. At this time, the first pick-up member 322 and the third pick-up member 333 are above the carrier 3321 of the second transfer module 332, so as to place the corner guard 60 on the carrier 3321 and transport the corner guard 60 to the right side far from the vibrating feeding assembly 31 through the transfer of the second transfer module 332, that is, as shown in Figure 1 This facilitates the second pick-up member 331 to pick up the corner guard 60 on the carrier 3321 and transplant it to the corner placement and positioning mechanism 22 of the corresponding corner guard tape application module 20 of the photovoltaic module 50.

[0063] For the first suction member 322 and the third suction member 333, they are identical in structure and different from the structure of the second suction member 331. Since the poses of the two positioning slots 33211 on the carrier 3321 on the second transfer 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 module 50. Therefore, when the corner guard 60 is conveyed from the left side to the right side of the second transfer module 332 by the carrier 3321, sucked by the second suction member 331 and transferred to the corner guard placement and positioning mechanism 22 of the corresponding corner guard taping module 20, there is no need to adjust the pose of the corner guard 60 anymore. Thus, the third suction member 333 only needs to move vertically up and down and horizontally (including in the first direction and the second direction), and there is no need to rotate for pose adjustment. When the first suction member 322 and the third suction member 333 suck the corner guard 60 from the flexible vibrating disk 312, the pose of the corner guard 60 is disorderly, that is, it does not exactly correspond to the poses of the two corners on the left side of the photovoltaic module 50 and the poses of the two positioning slots 33211 on the jig, that is, the poses of the two corners on the right side. Therefore, it is necessary to adjust the pose of the corner guard 60. Thus, in addition to the vertical lifting function and the horizontal moving function, the first suction member 322 and the third suction member 333 also have a rotation function around the vertical line. The purpose of rotation is to adjust the pose of the corner guard 60. That is to say, the third suction member 333 should also include a second vertical rotation driving member 3331 that drives the third suction member 333 to rotate around the vertical line, a third vertical displacement driving member 3332 that drives the third suction member 333 and the second vertical rotation driving member 3331 to move vertically up and down, and a third horizontal displacement driving member that drives the third suction member 333, the second vertical rotation driving member 3331 and the third vertical displacement driving member 3332 to move horizontally, that is, in the first direction. The second suction member 331 only includes the second suction member 331, a second vertical displacement driving member 3311 that drives the second suction member 331 to move vertically up and down, and a second horizontal displacement driving member 3312 that drives the second suction member 331 and the second vertical displacement driving member 3311 to move horizontally, that is, in the first direction.

[0064] For the first suction member 322, the second suction member 331 and the third suction member 333, as Figures 14 to 16As shown, all of them include four suction cups arranged in an L shape, and each protective arm of the corner guard 60 corresponds to two suction cups. For the first horizontal displacement driving member 325, the second horizontal displacement driving member 3312, and the third horizontal displacement driving member, they are of the structure of a conventional combination of a motor and a belt, which will not be described and defined herein. Those skilled in the art can easily understand and implement them. For the first vertical displacement driving member 324, the second vertical displacement driving member 3311, and the third vertical displacement driving member 3332, they can be selected as conventional cylinders, which will not be described and defined herein. Those skilled in the art can easily understand and implement them. For the first vertical rotation driving member 323 and the second vertical rotation driving member 3331, they can be selected as conventional rotation motors. Similarly, they will not be described and defined herein. Those skilled in the art can easily understand and implement them.

[0065] 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, they both correspond 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 both arranged on the first truss 321, in order to reduce the complexity of the structure and avoid interference during movement, in this embodiment, one first suction member 322 and one third suction member 333 are integrated together, and the other first suction member 322 and the other third suction member 333 are integrated together. The two third suction members 333 are arranged inside the two first suction members 322, that is, the two first suction members 322 are arranged at the front and rear ends as shown in Figure 14 Specifically, as shown in Figure 1 a first suction member 322 and a third suction member 333 at the front end shown are installed on the same fixed substrate and are driven to move synchronously in the horizontal direction, that is, in the first direction. Similarly, a first suction member 322 and a third suction member 333 at the rear end are installed on the same fixed substrate (not marked) and are driven to move synchronously in the horizontal direction, that is, in the first direction. That is to say, the third horizontal displacement driving member and the first horizontal displacement driving member 325 are the same driving member, and they are both driving motors as shown in Figure 14 and Figure 16 shown.

[0066] Compared with the feeding module 30 of the prior art in the background art, the feeding module 30 of this embodiment only needs to set a material bin 311 and a flexible vibrating disk 312 on one side of the first transmission module 10, without setting two vibrating feeding disks. The transplanting and feeding of the corner guards 60 at the four corners of the photovoltaic module 50 are realized through two sets of feeding components respectively, which is simpler in structure and smaller in floor area. After testing, the equipment beat of this embodiment is about 16 s, and the efficiency is relatively high.

[0067] Embodiment 2

[0068] Different from Embodiment 1, the number of side tape attaching modules 40 in this embodiment is two. Specifically, referring to Figure 3 , first tapes 70 are respectively pasted at the corner guards 60 at the four corners of the photovoltaic module 50, and a second tape 80 is 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 tapes and two second tapes 80. The two second tapes 80 are opposite and staggered. For the side tape attaching module 40, the structure is the same as that in Embodiment 2 and will not be elaborated. The difference lies in the different number of side tape attaching modules 40. In this embodiment, the number of side tape attaching modules 40 is two and they are relatively staggered.

[0069] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention.
