The junction box needs to be passed through the bus bar led out from the photovoltaic module board to make the bottom of the junction box bonded to the glue-coated part. After bonding, the two bus bars inserted in the wire box are bent and welded to form a current path.

[0097] See attached Figure 1 A junction box installation line includes a high-temperature tape removal station 100, a glue dispensing station 200, an installation station 300 and a loading station 400, and each station is connected in series in sequence through a photovoltaic module conveying mechanism 500.

[0098] The high temperature tape removal station 100 is provided with a high temperature tape removal module 1 for removing the high temperature tape on the photovoltaic module.

[0099] The glue dispensing station 200 is provided with a glue dispensing module 2 for dispensing glue at the area where the high temperature adhesive tape is torn off on the photovoltaic module.

[0100] The loading station 400 is provided with a loading module 3 for arranging and positioning the junction boxes on the junction box placement table 5 .

[0101] The installation station 300 is provided with a junction box installation module 4 for taking a junction box from a junction box placement table 5 and installing the junction box at a glue point of a photovoltaic module.

[0102] The photovoltaic component is first transported to the high-temperature tape removal station 100, where the high-temperature tape is torn off by the high-temperature tape removal module 1, and then transported to the glue dispensing station 200, where the glue dispensing module 2 applies glue to the area after the high-temperature tape is torn off. After the glue is applied, the photovoltaic component continues to be transported to the installation station 300. At the same time, the loading module 3 at the loading station 400 loads and arranges the required junction boxes, and takes them and positions them on the junction box placement table 5. Therefore, when the photovoltaic component is transported to the installation station 300, the junction box installation module 4 can take the junction box and install it by connecting it to the bus bar on the photovoltaic component. Finally, the photovoltaic component with the junction box installed is unloaded from the tail end of the installation station 300.

[0103] The entire assembly line connects multiple installation devices in the prior art into one, shortening the connection time between each process step, making the process flow of junction box installation smoother and greatly improving the work rhythm.

[0104] In this embodiment, the photovoltaic module conveying mechanism 500 adopts a belt conveyor, and each workstation is arranged with multiple belt conveyors in parallel.

[0105] In this embodiment, the high temperature adhesive tape removal module 1 includes a high temperature adhesive tape removal mechanism, a driving mechanism 16 and a high temperature adhesive tape recovery mechanism.

[0106] See attached Figure 3-10 The mechanism for tearing off the high-temperature adhesive tape comprises a shaping component 11 for correcting the busbar, a scooping component 12 for scooping up the high-temperature adhesive tape, and a tearing component 13 for tearing off the high-temperature adhesive tape.

[0107] The shaping component 11 is configured to straighten the busbar so that the busbar is in a vertical state. The shaping component 11 can adopt the straightening module in the high-temperature adhesive tape removal device and method, the junction box installation device and installation method with application number 202310315332.8, see Figure 8 .

[0108] The scooping assembly 12 includes a blowing block 121 and shovels 122 arranged on both sides of the blowing block 121; the blowing block 121 is lifted and lowered by the block driving cylinder 123, pressed down or suspended between the two bus bars, and supplies air to the high-temperature adhesive tape; the two shovels 122 are extended and retracted by the shovel extension cylinder 124 and lifted and lowered by the shovel lifting cylinder 125, so as to scoop up the high-temperature adhesive tape on both sides. When the scooping assembly 12 performs the scooping operation, the blowing block 121 blows air to the high-temperature adhesive tape so that the high-temperature adhesive tape loses its stickiness and is easy to detach from the photovoltaic module. Figure 6 .

[0109] The tearing assembly 13 includes a pair of tearing jaws 131, a tearing cylinder 132 and an inserting cylinder 133. The pair of tearing jaws 131 are driven by the inserting cylinder 133 to be inserted above the two shovel pieces 122 and arranged on both sides of the blowing block 121. The tearing jaws 131 are driven by the tearing cylinder 132 to clamp the high-temperature adhesive tape scooped up by the scooping assembly 12. After the scooping assembly 12 scoops up the high-temperature adhesive tape, the block driving cylinder 123 drives the blowing block 121 to move upward, and the tearing cylinder 132 drives the two tearing jaws 131 to be inserted above the two shovel pieces 122. The tearing cylinder 132 drives the two tearing jaws 131 to clamp the high-temperature adhesive tape. Figure 7 .

[0110] The driving mechanism 16 drives the shaping component 11, the scooping component 12, and the tearing component 13 to perform multi-dimensional movements. The driving mechanism 16 is a mechanical arm. Figure 2 .

[0111] See attached Figure 2 The high-temperature adhesive tape recovery mechanism is arranged at the output end of the high-temperature adhesive tape tearing station 100, and is used to recover the high-temperature adhesive tape torn off by the high-temperature adhesive tape tearing mechanism. The high-temperature adhesive tape recovery mechanism includes an adhesive tape recovery box 14 and an adhesive tape conveyor belt 15. The adhesive tape recovery box 14 has an outlet connected to the adhesive tape conveyor belt 15.

[0112] During the process of tearing off the high-temperature tape, the high-temperature tape can be first scooped up by the scooping component 12, and then the high-temperature tape can be torn off by the tearing component 13. Then the shaping component 11 straightens and corrects the bus bar under the high-temperature tape, and finally the blowing block 121 blows the torn high-temperature tape into the tape recovery box 14 on the high-temperature tape recovery mechanism, and finally falls onto the tape conveyor belt 15 through the outlet, and the tape conveyor belt 15 transports the unloaded material.

[0113] In this embodiment, there are three groups of bus bars in each row on the photovoltaic assembly to be installed, two of which need to be installed with wired junction boxes, and the other group needs to be installed with a wireless junction box.

[0114] See attached Figure 1 In this embodiment, the high-temperature tape tearing off mechanism is arranged into two groups, and each group of the high-temperature tape tearing off mechanism includes various components integrated and installed into an integral structure, and each integral structure is driven by a driving mechanism 16, and the two driving mechanisms 16 are respectively arranged on both sides of the high-temperature tape tearing off station 100, so that the driving mechanisms 16 have enough moving space; during operation, since the high-temperature tape on three groups of bus bars needs to be torn off, one of the driving mechanisms 16 needs to work twice, and this method has a lower beat.

[0115] In other embodiments, in order to improve the working rhythm, the high-temperature adhesive tape tearing mechanism can also be set to three groups, and each group of the high-temperature adhesive tape tearing mechanism includes various components integrated and installed as an integral structure, and each integral structure is driven by a driving mechanism 16; specifically, each integral structure is arranged on a linear module, and the linear module is connected to the driving end of a driving mechanism 16. This setting method can reduce the use of the driving mechanism 16, and the linear module can also adjust the spacing between the integral structures according to the spacing of each group of bus bars (not shown in the figure).

[0116] In other embodiments, each integral structure can also be driven by a driving mechanism 16, each driving mechanism 16 is arranged on a linear module, and the linear module can also adjust the spacing between the driving mechanisms 16 according to the spacing of each group of bus bars, etc. Fig.24 .

[0117] In other embodiments, the high temperature adhesive tape tearing mechanism is provided in three groups, and the scooping assembly 12 and the tearing assembly 13 included in each group of the high temperature adhesive tape tearing mechanism are integrated and installed as an integral structure, and the shaping assembly 11 included is a separate structure. Each integral structure or each separate structure is driven by a driving mechanism 16, or is driven by a driving mechanism 16, which can greatly improve the work rhythm.

[0118] When each integrated structure or each separate structure is driven by a driving mechanism 16 respectively, that is, one integrated structure is driven by a driving mechanism 16 and one separate structure is driven by a driving mechanism 16, each driving mechanism 16 can be arranged on a linear module (not shown in the figure).

[0119] When each integrated structure or each separate structure is driven by a driving mechanism 16, that is, each integrated structure is driven by a driving mechanism 16, and each separate structure is driven by a driving mechanism 16, then each integrated structure or each separate structure can be arranged on a linear module, and the linear module is connected to the driving end of a driving mechanism 16, see Fig.23 .

[0120] See attached Figure 1 In this embodiment, the dispensing module 2 includes a dispensing machine and a dispensing robot arm that drives the dispensing machine to move in multiple dimensions.

[0121] See attached Figure 1 and attached Fig.11 In this embodiment, the loading module 3 includes a wired junction box loading component 31, a wireless junction box loading component 32, and a junction box transfer component 33 for picking up and positioning the junction box transported by the junction box loading component on the junction box placement table 5.

[0122] The wired junction box loading components 31 are arranged in two parallel rows, and the wireless junction box loading component 32 is arranged in one row.

[0123] See attached Fig.12 The wired junction box loading assembly 31 includes a feeding conveyor line 311, a discharging conveyor line 312, and a clamping and flipping group 313 arranged between the two conveyor lines. The clamping and flipping group 313 is composed of two upper and lower groups of conveying units 3131. The two groups of conveying units 3131 are flipped by a flipping drive and are clamped and moved away from each other by a linear drive.

[0124] Among them, the two conveyor lines and the two groups of conveying units 3131 are all belt conveyors, and each belt conveyor can move independently. The conveying unit 3131 located below is arranged coplanar with the two conveyor lines to facilitate horizontal movement of the wired junction box for loading and unloading.

[0125] When the wired junction box moves between the two conveying units 3131 and the wired junction box needs to be flipped, the two conveying units 3131 are linearly driven to move closer to each other until the surfaces of the two conveying units 3131 contact the wired junction box, and the wired junction box remains stable and does not slide under the clamping action of the two conveying units 3131, so that the two conveying units 3131 can drive the wired junction box to flip under the flipping drive. After flipping, the two conveying units 3131 are linearly driven to move away from each other so that the wired junction box can be transported to the discharge conveyor line.

[0126] See attached Figure 13-14 The linear drive includes two groups of clamping devices and a linear drive device that drives the two groups of clamping devices to move closer to each other and away from each other. The two groups of clamping devices are relatively arranged on both sides of the clamping and flipping group 313, and each clamping device has two clamping members 3132. Both clamping members 3132 can be claws. The two clamping members 3132 clamp and fix the frames of the two conveying units 3131 respectively. The linear drive device adopts a finger cylinder 3133. The two clamping members 3132 can drive the two conveying units 3131 to move away from each other or closer to each other through the drive of the finger cylinder 3133.

[0127] The above-mentioned linear drive also includes two mounting seats, which are respectively arranged on both sides of the two conveying units 3131, and the two sets of clamping devices are respectively installed on the two mounting seats.

[0128] See attached Figure 14-15 In order to facilitate the equal exchange of the positions of the two conveying units 3131 before and after flipping without offset, two sets of clamping devices are arranged in the middle position of the two conveying units 3131 and installed at the output end of the flip drive. The two sets of clamping devices perform flipping movement around a horizontal flip axis under the drive of the flip drive.

[0129] The flip drive comprises a transmission part and a driving part 3137, and the output end of the transmission part is connected to the mounting seat of the linear drive. The transmission part includes a synchronous belt 3134 and two synchronous pulleys 3135 driving the synchronous belt 3134, wherein one synchronous pulley 3135 is fixed to a linear drive mounting seat, and the other synchronous pulley 3135 is fixedly arranged on a mounting plate 3136; a driving part 3137 is fixedly arranged on the mounting plate 3136, and the driving part 3137 has a driving end, and a connecting plate 3138 slidably arranged on the mounting plate 3136 is provided between the driving end and the synchronous belt 3134, and the sliding direction of the connecting plate 3138 is consistent with the transmission direction of the transmission part, and optionally, a guide rail is provided on the mounting plate 3136, and the extending direction of the guide rail is consistent with the transmission direction of the transmission part, and the connecting plate 3138 moves linearly on the guide rail; the connecting plate 3138 has a first end and a second end, the first end is fixedly connected to the driving end, and the second end clamps and fixes the synchronous belt 3134.

[0130] When the product needs to be flipped, the driving part 3137 works, and the driving end drives the connecting plate 3138 to move upward along the guide rail through the first end of the connecting plate 3138. The second end of the connecting plate 3138 clamps and fixes the synchronous belt 3134, and the synchronous belt 3134 drives the two synchronous pulleys 3135 to rotate; wherein, when the synchronous pulley 3135 fixedly connected to the clamping device rotates, it drives the clamping device to rotate together, and then the clamping device drives the clamping and conveying belt group to perform a flipping action.

[0131] Optionally, the driving part 3137 is a cylinder, which has lower cost than motor drive.

[0132] When the flip is completed, the driving part 3137 stops working, and the connecting plate 3138 returns to its original position to the starting end of the sliding path of the connecting plate 3138, that is, the bottom end of the guide rail in this embodiment, and waits for the next upward movement. When the connecting plate 3138 falls back, in order to avoid it colliding with the driving part 3137 and generating a large impact, an oil pressure buffer 3139 can be arranged under the connecting plate 3138. The oil pressure buffer 3139 is fixed on the mounting plate 3136, which can buffer the impact force when the connecting plate 3138 falls back.

[0133] In order to determine the orientation of the wired junction box and then determine whether the wired junction box needs to be flipped, the present embodiment also includes a visual detection mechanism (not shown in the figure) for detecting the orientation of the product, and the visual detection mechanism is arranged above the feeding conveyor line 311; the visual detection mechanism sends a signal to the controller according to whether the orientation of the product it detects is forward or reverse, and the controller controls the entire wired junction box loading assembly 31 after making a judgment.

[0134] Optionally, the visual inspection mechanism includes an image acquisition circuit composed of an industrial camera or a CCD / CMOS sensor, which is a prior art well known to those skilled in the art. In actual use, those skilled in the art can flexibly select a specific visual inspection mechanism as needed. Since the visual inspection mechanism is not the invention point of this case, it will not be described in detail in this case.

[0135] See attached Fig.12 The wireless junction box loading assembly 32 includes a feed conveyor line 321 and a feed conveyor line 322. The feed conveyor line 321 is arranged between the two feed conveyor lines 321, and the feed conveyor line 322 is horizontally erected on the feed conveyor line 321. This arrangement saves space and is also convenient for observing the loading situation of the junction box.

[0136] See attached Fig.16 The junction box transfer assembly 33 includes a first gripping structure 331 for picking up the junction box, and the first gripping structure 331 is driven by a transfer robot 332. The first gripping structure 331 may include a pair of gripping claws, and the pair of gripping claws are driven by a gripping claw cylinder to grip the junction box.

[0137] See attached Fig.17 The junction box installation module 4 includes a junction box installation component 41 and an installation robot arm 42 that drives the junction box installation component 41 to move in multiple dimensions.

[0138] See attached Figure 19-22 The junction box installation assembly 41 includes a second clamping structure 411 for picking up the junction box, an expansion structure 412 for bending the bus bar, and a vibration source 413 for providing horizontal vibration for the second clamping structure 411, and the direction of the horizontal vibration is perpendicular to the installation direction of the junction box.

[0139] The second clamping structure 411 can adopt a pair of clamping blocks 4111 and a pair of return blocks 4112. The two pairs of clamping structures are driven by cylinders to clamp the junction box in the x and y directions respectively, and limit the four end faces of the box body of the junction box, so as to accurately control the position of the box body of the junction box, which is convenient for the subsequent installation of the junction box body.

[0140] The expansion structure 412 includes a pair of expansion blocks 4121, which are distributed side by side with the two bus bars. When the two bus bars pass through the bus bar holes on the junction box taken by the second clamping structure 411, the pair of expansion blocks 4121 are located between the two bus bars. The pair of expansion blocks 4121 are driven to push apart and bend the two bus bars. The pair of expansion blocks 4121 and the pair of return blocks 4112 share a common cylinder as a drive. After the two pairs of clamping structures take the junction box, the bent parts of the two expansion blocks 4121 are located between the two bus bar perforations on the junction box. When the two bus bar perforations of the junction box correspond to the two bus bars and are perforated, the pair of expansion blocks 4121 are located between the two bus bars. At this time, the cylinder drives the two pairs of clamping structures to loosen the junction box, and at the same time drives the two expansion blocks 4121 to push the bus bars penetrated in the junction box to both sides, so that the bus bars are bent, which is convenient for subsequent welding between the bus bars and the junction box.

[0141] The vibration source 413 is a vibrator or the robotic arm.

[0142] When the vibration source 413 is a vibrator, the vibrator includes a floating outer plate 4131 , a floating inner plate 4132 , a motor 4133 and an eccentric wheel 4134 .

[0143] The motor 4133 is fixed on the mounting frame, the eccentric wheel 4134 is fixed on the output shaft of the motor 4133, the floating inner plate 4132 is fixed on the eccentric wheel 4134, and the floating outer plate 4131 is fixedly connected to the clamping structure.

[0144] There is a sliding limit in the x direction between the floating outer plate 4131 and the mounting frame of the junction box mounting assembly 41 , and there is a sliding limit in the y direction between the floating inner plate 4132 and the floating outer plate 4131 , and the sliding limit is a cross roller guide rail.

[0145] The vibration source 413 is used to maintain a slight reciprocating motion in the x direction and a slight reciprocating motion in the y direction when the junction box installation component 41 installs the box body part of the junction box on the bus bar, so that the junction box installation component 41 is in continuous vibration, which facilitates the bus bar to pass through the bus bar through-hole of the box body part of the junction box, further improving the installation efficiency of the junction box, and avoiding direct rigid connection between the bus bar and the through-hole, thereby ensuring the installation quality of the junction box.

[0146] The junction box installation assembly 41 also includes a seam expansion mechanism, which includes an insert block 414, and the two plug-in ends of the insert block 414 correspond one-to-one to the two bus bar through-holes on the junction box. The insert block 414 is connected to the installation frame through a connecting frame; the middle part of the plug-in end is consistent with the standard bus bar through-hole, and the output end of the plug-in end is gradually retracted from top to bottom so as to be inserted into the bus bar through-hole for seam expansion.

[0147] Before the second clamping structure 411 clamps the junction box, the expansion mechanism can be used to expand or correct the position of the busbar holes that do not meet the standards, thereby facilitating the subsequent insertion of the busbar into the junction box and further improving the installation efficiency of the junction box.

[0148] In other embodiments, the junction box installation assembly 41 may also be composed of a busbar straightening device with application number 202323517958.1 and a second clamping structure 411, see Fig.18 .

[0149] In this embodiment, the junction box installation assembly 41 is provided in two groups, each group of the junction box installation assembly 41 is driven by an installation robot arm 42, and the two installation robot arms 42 are arranged on both sides of the installation station 300. Figure 1 .

[0150] In other embodiments, in order to improve the working rhythm, the junction box installation assembly 41 can be set to three groups, and each group of the junction box installation assembly 41 can also be driven by a mounting robot arm 42. Specifically, each group of the junction box installation assembly 41 is arranged on a linear module, and the linear module is connected to the driving end of an mounting robot arm 42 (not shown in the figure).

[0151] This embodiment also provides a junction box installation process, which uses the above-mentioned junction box installation line and includes the following steps:

[0152] The conveying mechanism conveys the photovoltaic module to the high-temperature tape removal station 100, the shoveling component 12 shovels the high-temperature tape on the photovoltaic module, the tearing component 13 clamps and tears off the scooped high-temperature tape, and the shaping component 11 performs position limiting shaping on the four sides of the busbar;

[0153] The conveying mechanism on the high-temperature adhesive tape removal station 100 conveys the photovoltaic module with the high-temperature adhesive tape removed to the glue dispensing station 200, and the glue dispensing robot arm carries the glue dispensing machine to dispense glue at the area where the high-temperature adhesive tape is torn off on the photovoltaic module;

[0154] The conveying mechanism on the glue dispensing station 200 conveys the glued photovoltaic module to the installation station 300, the junction box transfer component 33 transfers the junction box provided by the loading module 3 to the junction box placement position on the junction box placement table 5, and the junction box installation module 4 takes the junction box positioned on the junction box placement table 5, installs the junction box to the bus bar on the photovoltaic module and bonds it with the glue dispensing glue;

[0155] The conveying mechanism on the installation station 300 conveys the photovoltaic components with the junction boxes installed to the unloading station.

[0156] Steps for loading the junction box:

[0157] The wireless junction box is sequentially transported via the feeding conveyor line 322 and the unloading conveyor line 321. At the output end of the unloading conveyor line 321, the junction box transfer assembly 33 grabs it and transfers it to the junction box placement position on the junction box placement table 5.

[0158] The wired junction box is sequentially conveyed through the feed conveyor line 311, the clamping and turning assembly 313, and the discharge conveyor line 312. At the output end of the discharge conveyor line 312, the junction box transfer assembly 33 grabs it and transfers it to the junction box placement position on the junction box placement table 5.

[0159] When the wired junction box needs to be flipped, the wired junction box is stopped when it is transported to the clamping and flipping group 313, and the upper and lower conveying units of the clamping and flipping group 313 clamp the wired junction box under linear drive, and after clamping, flip the wired junction box under flipping drive.
