Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic module assembly equipment, specifically to a corner protector tape application module and equipment for the photovoltaic module lamination process. Background Technology

[0002] In the manufacturing process of photovoltaic modules, lamination is a core process. Using a laminator, the laminated structure, consisting of front glass, back glass, solar cells, and encapsulating film, is pressed into a single unit. This protects the solar cells from external environmental influences during power generation, extending the lifespan of the photovoltaic module. During lamination, corner protectors are installed at the four corners of the photovoltaic module and secured to the module with tape. The purpose of the corner protectors is to limit the lamination thickness (preventing over-pressing from making the module too thin or under-pressing from making it too thick). In other words, it limits the amount of adhesive overflow between the two glass panes during lamination, thus achieving a controlled thickness. Simultaneously, it also positions the photovoltaic module to prevent horizontal misalignment of certain parts during lamination, which could lead to poor product quality after lamination.

[0003] In existing technologies, the corner protectors used in the lamination process of photovoltaic modules are mostly L-shaped or right-angled, and the tape is applied in a C-shape along the two straight edges of the corner protector, with the two ends of the tape respectively bonded to the upper and lower surfaces of the photovoltaic module inside the corner protector. Because this method of applying tape to corner protectors requires one tape on each of the two straight edges, two sets of tape application modules are needed. That is, one tape application module is required on the outer side of each straight edge of the corner protector. This results in a complex equipment structure, a large footprint, and high cost.

[0004] Therefore, it is necessary to provide corner protector tape application modules and equipment for the photovoltaic module lamination process to solve the above problems. Utility Model Content

[0005] In view of at least one of the above-mentioned technical problems, the purpose of this utility model is to provide a corner protector tape application module and equipment for the photovoltaic module lamination process.

[0006] The technical solution of this utility model is:

[0007] One objective of this utility model is to provide a corner protector tape application module for the photovoltaic module lamination process. The corner protector tape application module can move closer to or further away from the corresponding corner of the photovoltaic module to be laminated, and includes a fixed-length tape cutting assembly, a corner protector placement and positioning mechanism, and a tape application mechanism.

[0008] The corner protector placement and positioning mechanism is located near the outer side of the corresponding corner of the photovoltaic module, and is used to fix the corner protector to be installed and press the corner protector against the outer side of the corresponding corner of the photovoltaic module.

[0009] The fixed-length tape assembly is located on the side of the corner protector placement and positioning mechanism away from the photovoltaic module. A section of tape is cut to be used to stick and fix the corner protector to the corresponding corner of the photovoltaic module, and one end of the tape is folded over to form a folded part.

[0010] The tape attaching mechanism is rotatably disposed between the fixed-length tape cutting assembly and the corner protector placement and positioning mechanism. It is used to adsorb and fix the tape to be cut when the tape is cut, and after the corner protector is fixed, to fold the cut tape with the apex of the corresponding corner protector as the folding starting point so that both ends of the tape section are folded in the same direction and respectively flatly attached to the upper and lower surfaces of the photovoltaic module, wherein the folded part is located on the upper surface of the photovoltaic module.

[0011] Preferably, the fixed-length tape cutting assembly includes a tape reel frame, an upper clamping mechanism, a folding mechanism, a lower clamping mechanism, and a tape cutting mechanism, with the tape roll mounted on the tape reel frame;

[0012] The folding mechanism is located on the tape feeding path of the tape reel frame and is used to fold the free end of the tape to be cut toward the end to be cut.

[0013] The lower clamping mechanism is vertically and vertically disposed below the tape reel frame, the upper clamping mechanism is disposed between the tape reel frame and the upper clamping mechanism, and the lower clamping mechanism clamps the folded free end to form the folded part and clamps the folded part to pull the tape out a preset length in a direction away from the upper clamping mechanism.

[0014] The tape-cutting mechanism is located between the upper clamping mechanism and the lower clamping mechanism and is close to the upper clamping mechanism, so as to cut the end of the tape to be cut after the tape is pulled down to a preset length by the lower clamping mechanism.

[0015] Preferably, the folding mechanism includes a first driving member and a first clamping member and a second clamping member that move relative to each other driven by the first driving member, wherein the first clamping member and the second clamping member have a separated open state and a close closed state.

[0016] In the open state, the free end of the tape passes between the first clamping member and the second clamping member;

[0017] The clamping end of the first clamping member is configured as a first clamping segment, and the clamping end of the second clamping member is configured as a second clamping segment. In the closed state, the first clamping segment and the second clamping segment are clamped relative to each other on both sides of the free end of the tape and staggered so that the free end is folded toward the end to be cut.

[0018] Preferably, both the first clamping section and the second clamping section are cylindrical structures.

[0019] Preferably, the lower clamping mechanism can be driven to move horizontally toward or away from the tape attaching mechanism. The lower clamping mechanism includes an openable clamping assembly and a third driving member that drives the clamping assembly to move up and down toward or away from the folding mechanism. The clamping assembly includes a first clamping block and a second clamping block arranged opposite to each other on both sides of the outer surface of the tape, and a clamping block cylinder that drives the first clamping block and the second clamping block to move toward or away from each other.

[0020] Preferably, the upper end of the first clamping block has a third clamping section and the upper end of the second clamping block also has a fourth clamping section. Either the third clamping section or the fourth clamping section protrudes towards the other so that a clearance space is formed between the lower part of the third clamping section and the lower part of the fourth clamping section to avoid the first clamping member and the second clamping member. When the lower clamping mechanism clamps the folded part and pulls it down by a preset length, the first clamping member and the second clamping member horizontally retract out of the clearance space.

[0021] Preferably, the upper clamping mechanism includes a fixed pressure plate and a movable pressure plate arranged opposite to each other on both sides of the outer surface of the tape, and a second driving member that drives the movable pressure plate to move closer to or away from the fixed pressure plate;

[0022] The fixed pressure plate has a guide groove recessed on the side facing the movable pressure plate and extending along the tape feeding path, and has several adsorption holes communicating with the guide groove. The movable pressure plate has a pressing protrusion that matches the guide groove at one end facing the fixed pressure plate. The pressing protrusion is embedded in the guide groove to clamp and fix the upper end of the tape to be cut. When the movable pressure plate separates from the tape, the adsorption holes adsorb and adhere the tape to the fixed pressure plate.

[0023] Preferably, the tape attaching mechanism is rotatable about a horizontal axis such that its attaching end faces the lower clamping mechanism or the photovoltaic module and is adsorbed onto the adhesive back of the tape before facing the lower clamping mechanism and the tape cutting mechanism cuts the tape.

[0024] The tape application mechanism includes an application component with two opposing adsorption surfaces at one end and a horizontal rotation drive component that drives the application component to rotate around a horizontal axis.

[0025] The attachment assembly includes a mounting base, two adsorption blocks, two tape application mechanisms, two elastic abutment components, and a sliding plate. The mounting base is connected to the horizontal rotation drive component and has a horizontally extending clearance groove in the middle. The two adsorption blocks are respectively fixed to the upper and lower ends of the corresponding openings of the clearance grooves on the mounting base, and the outer end faces of the two adsorption blocks are formed as adsorption surfaces. Each adsorption block has several blow-suction holes on its adsorption surface. The two tape application mechanisms are fixed opposite to and spaced apart on the upper and lower inner walls of the openings of the clearance grooves. Each tape application mechanism includes an application roller that rotates around a horizontal line. Elastic abutment members are disposed on opposite sides of the mounting substrate in the thickness direction. Each elastic abutment member includes a abutment rod and an elastic element sleeved on the abutment rod. One end of the abutment rod is movably inserted through the end of the mounting substrate opposite to the end with the clearance groove, and the other end is fixed to the sliding plate. The axis of the abutment rod is parallel to the length direction of the clearance groove. The elastic element applies a biasing force to the sliding plate, causing the sliding plate to tend towards the opening of the clearance groove. In the initial state, the sliding plate is positioned between the two attachment rollers due to the biasing force of the elastic abutment members.

[0026] When the horizontal rotation drive drives the adsorption surface of the attachment component toward the photovoltaic module to be installed with corner protectors, and the tape attachment mechanism is driven to move toward the corner protector of the corresponding corner of the photovoltaic module, the middle section of the tape adsorbed by the two adsorption blocks is pressed and fixed outside the top corner of the corresponding corner protector, and the sliding plate is pressed by the corresponding corner protector and moves toward the clearance groove. The two attachment rollers respectively roll on the outer surfaces of the two ends of the tape to fold the two ends of the tape, whose middle section has been fixed outside the top corner of the corresponding corner protector, from the outside to the inside along the diagonal direction of the corner protector and flatten and stick them to the upper and lower surfaces of the photovoltaic module.

[0027] Preferably, the corner protector placement and positioning mechanism is driven to move toward or away from the corresponding corner of the photovoltaic module, and when moving toward, it is lifted vertically to press the corner protector against the corresponding corner of the photovoltaic module;

[0028] The corner protector placement and positioning mechanism includes two opposing and spaced-apart corner protector fixing platforms and pressure blocks respectively disposed on either of the corner protector fixing platforms. Each of the corner protector fixing platforms has a downwardly recessed fixing groove that matches one of the protective arms of the corner protector. After the corner protector is placed in the two fixing grooves of the two corner protector fixing platforms, the two pressure blocks press against the upper surfaces of the two protective arms of the corner protector respectively.

[0029] Another objective of this utility model is to provide a photovoltaic module lamination process equipment, including a transmission module extending along a first direction for conveying and positioning photovoltaic modules, and four corner protector and adhesive tape application modules as described in any one of the above, which are respectively movably disposed on the four outer corners of the transmission module and can move closer to or away from the corresponding corners of the photovoltaic modules to be laminated on the transmission module to realize the installation of corner protectors and the application and fixing of adhesive tape at each corner.

[0030] Compared with the prior art, the advantages of this utility model are:

[0031] This invention relates to a corner protector and adhesive tape application module and equipment for the photovoltaic module lamination process. Only one corner protector and adhesive tape application module is needed for each of the four corners of the photovoltaic module, reducing the number of modules and their footprint, resulting in a simpler structure and lower costs. Furthermore, it simplifies the subsequent tape removal process. Attached Figure Description

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0043] See Figures 1 to 7This utility model provides a corner protector tape application module for a photovoltaic module lamination process, mainly comprising three parts: a fixed-length tape cutting assembly 11, a corner protector placement and positioning mechanism 12, and a tape application mechanism 13. The fixed-length tape cutting assembly 11, the corner protector placement and positioning mechanism 12, and the tape application mechanism 13 are mounted on the same base (not shown) and are driven together to move towards or away from the corner of the photovoltaic module 40 corresponding to the corner protector tape application module 10. The corner protector placement and positioning mechanism 12 is closer to the photovoltaic module 40. When it approaches, the corner protector placement and positioning mechanism 12 first contacts the photovoltaic module 40 and presses the corner protector 50 fixed on it against the outside of the corner of the photovoltaic module 40. Then, the tape application mechanism 13 moves relative to the fixed-length tape cutting assembly 11 and the corner protector placement and positioning mechanism 12 along the diagonal direction of the corner protector 50 towards or away from the corner of the photovoltaic module 40 to adhere and fix the corner protector 50 to the corner of the photovoltaic module 40 using tape 60. More specifically, the corner protector placement and positioning mechanism 12 is located near the photovoltaic module 40 on the transmission module 20. It is used to fix the corner protector 50 to be installed and press the corner protector 50 against the outside of the corresponding corner of the photovoltaic module 40, so as to position the corner protector 50 at the corresponding corner of the photovoltaic module 40 before applying the adhesive tape 60. The fixed-length adhesive tape assembly 11 is located on the side of the corner protector placement and positioning mechanism 12 away from the photovoltaic module 40. A section of adhesive tape 60 is cut to be used to stick and fix the corner protector 50 to the corresponding corner of the photovoltaic module 40, and one end of the section of adhesive tape 60 is folded to form a folded part 61. The tape attaching mechanism 13 is rotatably disposed between the fixed-length tape cutting assembly 11 and the corner protector placement and positioning mechanism 12. It is used to adsorb and fix the tape 60 to be cut when the tape 60 is cut, and to adsorb and fix the tape 60 after the corner protector 50 is fixed to the corner of the photovoltaic module 40. After flipping, the cut tape 60 is attached to the corner protector 50 and the photovoltaic module 40. Specifically, the middle section of the tape 60 is pressed against the outside of the top corner of the corner protector 50, and the top corner of the corner protector 50 is used as the folding starting point to fold both ends of the tape 60 in the same direction and fix them flat on the upper and lower surfaces of the photovoltaic module 40, that is, the tape 60 is pasted along the diagonal of the corner protector 50.

[0044] Specifically, such as Figures 2 to 6 As shown, the fixed-length tape breaking assembly 11 mainly includes five parts: tape 60 reel frame 111, upper clamping mechanism 114, winding mechanism 112, lower clamping mechanism 115, and tape breaking mechanism 113.

[0045] Specifically, the tape 60 reel holder 111 is a conventional disc-shaped structure that can rotate around a horizontal line, and the tape 60 roll is mounted on the tape 60 reel holder 111. In this embodiment, the tape 60 reel holder 111 is located at the top, releasing the tape 60 downwards. The upper clamping mechanism 114, the folding mechanism 112, the lower clamping mechanism 115, and the tape 60 cutting mechanism 113 are all located below the tape 60 reel holder 111. The folding mechanism 112 is located on the tape 60 feeding path of the tape 60 reel holder 111, specifically as follows: Figure 2 or Figure 6 The tape 60 is shown below the discharge end of the tape reel 111. That is, after the tape 60 is fed out of the tape reel 111, it is pulled vertically downwards. The purpose of the folding mechanism 112 is to fold the free end of the section of tape 60 to be cut, i.e.,... Figure 6 The direction of the lower end toward the end to be cut, as shown, is... Figure 6 The tape 60 is folded upwards as shown. A lower clamping mechanism 115 is vertically movable and positioned below the tape 60 reel holder 111. The lower clamping mechanism 115 clamps the free end of the folded tape 60 to form a folded portion 61. Simultaneously, when descending, it pulls the tape 60 downwards by a certain length so that the end of the tape 60 to be cut is exactly on the same horizontal plane as the tape-cutting mechanism 113. An upper clamping mechanism 114 is positioned between the tape 60 reel holder 111 and the folding mechanism 112 to clamp the upper end of the tape 60 to be cut. The tape-cutting mechanism 113 is located between the upper clamping mechanism 114 and the lower clamping mechanism 115 and is close to the upper clamping mechanism 114. It should be noted that the tape-cutting mechanism 113 is located on the side of the tape 60 between the upper clamping mechanism 114 and the lower clamping mechanism 115. It can be driven to move horizontally towards or away from the tape 60. It is used to cut the end of the tape 60 to be cut by moving horizontally towards the tape 60 after the tape 60 is lowered and stretched to a preset length by the lower clamping mechanism 115.

[0046] Specifically, such as Figure 2 and Figure 4 As shown, the folding mechanism 112 includes a first driving member 1121 and a first clamping member 1122 and a second clamping member 1123 that move relative to each other driven by the first driving member 1121. The first clamping member 1122 and the second clamping member 1123 have a separated open state and a closed state. In the open state, the free end of the tape 60 passes between the first clamping member 1122 and the second clamping member 1123. For ease of description and distinction, the clamping end of the first clamping member 1122 is implemented as follows: Figure 4 The front end shown is the first clamping section (not shown), and the clamping end of the second clamping member 1123 is also as shown. Figure 4The front end shown is a second clamping section (not shown). In the closed state, the first clamping section and the second clamping section are clamped relative to each other on both sides of the free end of the tape 60, that is, as shown in the figure. Figure 4 The front and rear sides are shown, and they are vertically offset, one above the other, so that the free end of the tape 60 can be folded towards its end to be cut. For example, in this embodiment, the first clamping section is on top and the second clamping section is on the bottom. Thus, the free end of the lower end of the tape 60 is folded upwards by the clamping force of the first and second clamping sections. Preferably, the first and second clamping sections are cylindrical structures, similar to chopsticks. For the first driving member 1121, a conventional cylinder can be selected. It should be noted that in this embodiment, the folding mechanism 112 can move horizontally, specifically moving horizontally towards or away from the tape 60 between the upper clamping mechanism 114 and the lower clamping mechanism 115. The horizontal movement away is to prevent interference with the movement of the lower clamping mechanism 115 and the tape 60 during the process of the lower clamping mechanism 115 clamping the folded free end to form a fold 61 and pulling it down to a predetermined length. In this embodiment, as... Figure 4 As shown, both the folding mechanism 112 and the tape-breaking mechanism 113 are located on the rear side as shown in the figure, with the folding mechanism 112 positioned above the tape-breaking mechanism 113.

[0047] For the upper clamping mechanism 114, such as Figure 2 and Figure 4 As shown, this includes both surfaces along the tape 60, i.e. Figure 8 The fixed pressure plate 1141 and the movable pressure plate 1142 arranged opposite to each other on the left and right surfaces, and the drive of the movable pressure plate 1142 to move closer to or away from the fixed pressure plate 1141, are as follows: Figure 6 The second driving member 1143 is shown for left-right translation. In the figure, the fixed pressure plate 1141 and the movable pressure plate 1142 are arranged with a left-right gap, and the free end of the tape 60 passes downward through the gap between them. Preferably, the side of the fixed pressure plate 1141 facing the movable pressure plate 1142 has a recess on the side facing away from the movable pressure plate 1142, i.e., as shown... Figure 6 The indentation to the right, extending along the path of the tape feeder 60, is as shown. Figure 6As shown, a downward-extending and penetrating guide groove (not shown) corresponds to a pressing protrusion (not shown) that protrudes towards the fixed pressure plate 1141 and matches the guide groove at one end of the movable pressure plate 1142 facing the fixed pressure plate 1141. The pressing protrusion is embedded in the guide groove to clamp and fix the upper end of the tape 60 to be cut. Similarly, the second driving member 1143 can be a conventional cylinder. Preferably, the fixed pressure plate 1141 has several adsorption holes 11411 that communicate with the guide groove. The purpose of the adsorption holes 11411 is to adsorb and adhere the tape 60 to the fixed pressure plate 1141 when the movable pressure plate 1142 separates from the tape 60. Specifically, when the clamping mechanism 115 clamps the folded part 61 and pulls it down, the tape 60 is attracted and adhered to the guide groove on the fixed pressure plate 1141 by the adsorption hole 11411. This serves to guide the tape 60 and prevent it from falling out of the guide groove of the fixed pressure plate 1141, which would be detrimental to the subsequent pressing of the tape 60 by the movable pressure plate 1142.

[0048] For the lower clamping mechanism 115, such as Figure 3 As shown, it mainly includes a clamping assembly 1151 and a third driving member 1152. In this embodiment, the clamping assembly 1151 can be a conventional pneumatic clamping block mechanism, specifically including, as shown below... Figure 6The diagram shows a first clamping block 11511 and a second clamping block 11512 arranged opposite each other, and a clamping cylinder 11513 located below the first clamping blocks 11511 and 11512 to drive the first clamping blocks 11511 and 11512 to move closer to or further away from each other. The first clamping blocks 11511 and 11512 extend upwards, each with a clamping section at its upper end. For ease of description and distinction, the clamping section at the upper end of the first clamping block 11511 is described as the third clamping section 115111, and the clamping section at the upper end of the second clamping block 11512 is described as the fourth clamping section 115121. Both the third clamping section 115111 and the fourth clamping section 115121 extend outwards. In other words, both the first clamping block 11511 and the second clamping block 11512 are inverted L-shaped, wider at the top and narrower at the bottom. When the third clamping section 115111 of the first clamping block 11511 and the fourth clamping section 115121 of the second clamping block 11512 are clamped, there is a gap between the lower part of the third clamping section 115111 of the first clamping block 11511 and the lower part of the fourth clamping section 115121 of the second clamping block 11512. This gap forms a clearance space (not shown), which is to provide clearance for the folding mechanism 112. In other words, after the folding mechanism 112 clamps and folds the free end of the tape 60 (at this time, the folded portion 61 has not yet been formed), when the lower clamping mechanism 115 clamps the folded free end and the unfolded portion so that they are pressed together to form the folded portion 61, the folding mechanism 112 is not released at this time, that is, it is within the clearance space. After the folded portion 61 is formed, when the lower clamping mechanism 115 pulls the tape 60 downward, the folding mechanism 112 needs to first retract from the clearance space. As for the third driving member 1152, its purpose is to drive the clamping assembly 1151 to move upward, that is, closer to the folding mechanism 112, to clamp the folded free end to form the folded portion 61 and clamp it, or to move downward, that is, away from the folding mechanism 112, to pull the tape 60 downward to a predetermined length. For the third driving component 1152, an exemplary embodiment includes a rotary motor and a lead screw assembly and a vertical slide rail (not shown). The lead screw (not shown) is arranged vertically and connected to the driving end of the rotary motor (not shown). The left end of the clamping block cylinder 11513 of the clamping assembly 1151 is slidably connected to the vertical slide rail via a slider (not shown). Specific details are not described or limited. Preferably, the end face of the third clamping section 115111 of the first clamping block 11511 facing the second clamping block 11512 and the end face of the fourth clamping section 115121 of the second clamping block 11512 facing the first clamping block 11511 are respectively provided with rack-shaped anti-slip patterns (not shown) to increase friction during clamping and improve clamping reliability.

[0049] For the tape breaking mechanism 60 113, such as Figure 4As shown, this embodiment exemplifies a conventional pneumatic scissors 1131 mechanism. Specifically, it includes an openable pneumatic scissors 1131 and a mechanism for driving the pneumatic scissors 1131 to move towards or away from the tape 60. Figure 6 The fourth drive member 1132 is shown, which moves horizontally in the forward and backward direction. The fourth drive member 1132 can be a conventional cylinder.

[0050] In this embodiment, the tape application mechanism 13 is installed together with the fixed-length tape assembly 11 and can move horizontally synchronously towards or away from the photovoltaic module 40. The tape application mechanism 13 is located on the side of the lower clamping mechanism 115 closest to the photovoltaic module 40. Figure 6 As shown on the right. Furthermore, the lower clamping mechanism 115 can move horizontally towards or away from the tape attaching mechanism 13; that is, the lower clamping mechanism 115 can move along... Figure 6 The horizontal movement is shown in the left-right direction. That is, when the suction end of the tape attaching mechanism 13 rotates to face the lower clamping mechanism 115, there is a gap between them. At this time, after the lower clamping mechanism 115 moves towards the tape attaching mechanism 13, the tape 60 will be attracted by the suction end of the tape attaching mechanism 13, and then the tape cutting mechanism 113 will cut the end of the tape 60 to be cut. It should be noted that when the lower clamping mechanism 115 moves towards or away from the tape attaching mechanism 13, the upper clamping mechanism 114, the folding mechanism 112, the tape cutting mechanism 113, and the tape 60 reel holder 111 move together. That is, the upper clamping mechanism 114, the folding mechanism 112, the tape cutting mechanism 113, the tape 60 reel holder 111, and the lower clamping mechanism 115 are mounted on the same fixed plate (exemplarily as shown in the image). Figure 2 The front mounting plate shown is not labeled, while the tape attaching mechanism 13 is mounted on another mounting plate (exemplarily as shown in the image). Figure 2 On the rear mounting plate (not shown), the two mounting plates are slidably connected. Specifically, as shown... Figure 5 As shown, the tape application mechanism 13 includes an application assembly 131 and a horizontal rotation drive 132, the horizontal rotation drive 132 being able to rotate as shown in the figure. Figure 5 The horizontal axis extending forward and backward, as shown, rotates to drive the attachment assembly 131 to rotate synchronously so that its attachment end faces as... Figure 2 The lower clamping mechanism 115 on the left side, as shown, or oriented as... Figure 2 The photovoltaic module 40 is shown on the right. The horizontal rotation drive 132 is a conventional rotary motor.

[0051] For the attachment component 131, such as Figure 5As shown, it mainly includes a mounting base 1311, two adsorption blocks 1312, two adhesive tape application mechanisms, two elastic support members 1314, and a sliding plate 1315. The mounting base 1311 is connected to a horizontal rotation drive member 132 and has a horizontal extension in the middle, i.e., as shown... Figure 5 The clearance groove 13111 extends from right to left as shown. Two adsorption blocks 1312 are respectively fixed to the upper and lower ends of the corresponding openings of the clearance groove 13111 on the mounting base plate 1311, and the outer end faces of the two adsorption blocks 1312 are also as shown... Figure 5 The left end face shown is an adsorption surface. Each adsorption block 1312 has several suction holes 13121 on its adsorption surface. These holes provide suction when the adhesive tape 60 is adsorbed and fixed onto the attachment assembly 131, and blow the tape 60 away from the adsorption surface of the adsorption block 1312 when the tape 60 is attached and fixed to the corner protector 50 and the upper and lower surfaces of the photovoltaic module 40. Preferably, the two attachment blocks can be moved vertically to adjust the distance between them, in order to match tapes 60 of different lengths. The two tape-applying mechanisms are fixed relative to each other and spaced apart on the upper and lower inner walls of the opening of the clearance groove 13111. Each tape-applying mechanism includes a mounting block (not shown) horizontally fixed at the opening of the clearance groove 13111 and a mounting block installed on the outer end of the mounting block, i.e., as shown in the figure. Figure 5 The right end shown can be rotated relative to the mounting block as follows Figure 5 The attachment roller 1313 rotates horizontally in the front-to-back direction. Two elastic abutment members 1314 are positioned opposite each other on both sides of the mounting substrate 1311 in the thickness direction, i.e. Figure 5 The front and rear sides shown, and one end of any elastic abutment member 1314, are also as follows: Figure 5 The left end shown is movably connected to the left end of the mounting base plate 1311, and the other end is also as shown... Figure 5The right end shown is connected to the inner end of the sliding plate 1315. In the initial state, the sliding plate 1315 is positioned between the two attaching rollers 1313 of the two tape attaching mechanisms under the biasing force of the elastic support member 1314. When the horizontal rotation drive member 132 drives the adsorption surface of the attaching assembly 131 towards the corresponding corner of the photovoltaic module 40 to which the corner protector 50 is to be installed, and the tape attaching mechanism 13 is driven to move closer to the corner protector 50 of the photovoltaic module 40, the middle section of the tape 60 adsorbed by the two adsorption blocks 1312 is pressed and fixed at the apex corner of the corresponding corner protector 50 by the two attaching rollers 1313, and the sliding plate 1315 is pressed by the corresponding corner protector 50 and retracts towards the clearance groove 13111, so that the corner protector 50 enters the clearance groove 13111. The tape 60 is pressed flat onto the upper and lower surfaces of the corner protector 50 by the inner wall of the relief groove 13111. The two ends of the tape 60 extend horizontally along the diagonal of the corner protector 50 toward the inner side of the photovoltaic module 40. During this process, the two attaching rollers 1313 of the two tape attaching mechanisms roll and press against the outer surfaces of the two ends of the tape 60 to fold the two ends of the tape 60, which is already fixed at the top corner of the corner protector 50, from the outside to the inside and flatten them to stick to the upper and lower surfaces of the photovoltaic module 40.

[0052] For the elastic support component 1314, such as Figure 5 As shown, it includes a line as... Figure 5 The diagram shows a cylindrical abutment rod 13141 extending horizontally in a left-right direction and an elastic element 13142 (exemplarily a tubular straight spring) sleeved around the abutment rod 13141. The left end of the abutment rod 13141 movably passes through the left end of the mounting base plate 1311, which is the end opposite to the end with the clearance groove 13111. The right end of the abutment rod 13141 is fixed to the inner end of the sliding plate 1315, which is the left end, and the axis of the abutment rod 13141 is parallel to the extending direction of the clearance groove 13111, which is the length direction. The elastic element 13142 applies a biasing force to the sliding plate 1315, causing the sliding plate 1315 to tend towards the opening of the clearance groove 13111 and be located between the two attached rollers 1313.

[0053] The corner protector positioning mechanism 12 can be driven to move closer to or away from the corresponding corner of the photovoltaic module 40, and when moving closer, it presses the corner protector 50 against the corresponding corner of the photovoltaic module 40. It should be noted that in this embodiment, the corner protector positioning mechanism 12, the fixed-length tape assembly 11, and the tape attaching mechanism 13 are mounted on the same base plate and can be driven to move synchronously closer to or away from the corresponding corner of the photovoltaic module 40. Its specific structure is not described in detail or limited; reference can be made to the prior art mentioned in the background section. An exemplary example is... Figure 1 As shown, the corner protector placement and positioning mechanism 12 of this embodiment includes two opposite and spaced apart (i.e., as shown in the figure). Figure 1The corner protector fixing platform 121, arranged with relative spacing to avoid interference with the sides of the photovoltaic module 40, and the pressure block 122, which is vertically movable and rotatable around a vertical line, are respectively provided on each corner protector fixing platform 121. Each corner protector fixing platform 121 has a downwardly recessed fixing groove 1211 on its upper surface, near the other corner protector fixing platform 121, that matches the end of one of the protective arms of the corner protector 50 away from the apex angle of the corner protector 50. After the corner protector 50 is placed in the two fixing grooves 1211 of the two corner protector fixing platforms 121, the two pressure blocks 122 press against the upper surfaces of the two protective arms of the corner protector 50. Each corner protector fixing platform 121 is provided with a rotary lifting drive (not shown, but exemplarily a conventional motor-screw mechanism) for driving the rotation and lifting of its corresponding pressure block 122. It should be noted that the two corner guard fixing platforms 121 can be driven to move up and down synchronously in the vertical direction. The lifting drive mechanism (not shown) of the corner guard fixing platforms 121 is not described or limited, but is a conventional lifting cylinder. Optionally, a corner support positioning platform 30 (not described in detail, see the prior art description of the positioning mechanism in the background section) is also provided on the fixing base (not shown) of the corner guard fixing platforms 121, which is supported on the bottom surface of the photovoltaic module 40. The corner support positioning platform 30 and the two corner guard fixing platforms 121 are arranged opposite each other, i.e., as shown in the background section. Figure 1 As shown, the left and right sides are arranged opposite each other, and the corner protector fixing platform 121 is close to the tape attaching mechanism 13, that is, as Figure 1 As shown on the left, the corner support positioning platform 30 is away from the tape attaching mechanism 13, that is... Figure 1 The right side shown is the side closest to photovoltaic module 40.

[0054] See Figures 1 to 8 This embodiment also provides a photovoltaic module 40 lamination process equipment, including a transmission module 20 and four corner protector tape application modules 10 as described in the above embodiment. The transmission module 20 is positioned along... Figure 1 The front and back extension shown (it should be noted that the front and back here are not as shown) Figure 8 The front and back directions are not shown directly, but rather the side of the device facing the reader is called the front, and the side facing away from the reader is called the back. This facilitates the input and output of the photovoltaic module 40. The transmission module 20 is used for transporting the photovoltaic module 40 (including the input of the photovoltaic module 40 to be laminated and the output of the laminated photovoltaic module 40) and for positioning when placing the protective corner 50 and applying the adhesive tape 60. The structure and working principle of the transmission module 20 are not described here; it is a conventional transmission module for photovoltaic modules 40, existing technology, and not an innovation of this utility model. Those skilled in the art can easily understand and implement it. For ease of description and distinction, in this embodiment, the transport direction of the transmission module 20 is described as the first direction, as shown below. Figure 8The left and right directions shown are the second direction. The first and second directions are perpendicular in the same horizontal plane. The vertical direction is perpendicular to the first and second directions in space. The first direction, the second direction, and the vertical direction are mutually perpendicular in space, forming the three axes of a triangular coordinate system. The structure of the corner protector 50 is not described or limited, but can be referred to the description in Chinese invention patent publication number "CN116190493A". This is not an innovation of this utility model. It should be noted that the device in this embodiment also includes a feeding module for feeding the corner protector 50. The structure of the feeding module is not described or limited; it is a conventional combination of a mechanical suction nozzle and a vibrating feeding plate, which is easily known and implemented by those skilled in the art and is not an innovation of this utility model. For example, in this embodiment, the feeding module is located on both sides of the transmission module 20, that is, on both sides of the first direction or at both ends of the second direction. Figure 8 The left and right ends are shown.

[0055] In this embodiment, the four corner protector tape application modules 10 are respectively located on the outer sides of the four corners of the transmission module 20. They can move closer to or further away from the corresponding corners of the photovoltaic module 40 to be laminated on the transmission module 20 to complete the installation and fixation of the corner protectors 50 and the application of the tape 60. Compared with the prior art, each corner protector 50 only requires one module to complete the installation and tape application of the corner protector 50, resulting in a simpler structure, lower cost, and easier removal of the tape 60.

[0056] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
