When the existing photovoltaic junction boxes are produced, the assembly of the junction boxes is one of the most common steps, which can effectively improve the production efficiency of photovoltaic junction boxes.

[0003] For example, the photovoltaic module junction box cover assembly machine in the technical field of photovoltaic module assembly disclosed in the publication number: CN215509834U, includes a support assembly, including a bracket and a mounting frame, and the mounting frame is installed on the front side wall of the bracket; a transplanting and conveying assembly, the transplanting and conveying assembly is installed in the inner cavity of the mounting frame; a framing assembly, the framing assembly is placed on the front side of the transplanting and conveying assembly; a junction box cover storage mechanism, the junction box cover storage mechanism is installed on the bottom inner wall of the mounting frame; an installation assembly, including an installation bracket and an installation and placement manipulator.

[0004] Although the above-mentioned patented equipment saves labor costs, when assembling the junction box, its efficiency in aligning and feeding the junction box and its cover fittings is insufficient, and the overall assembly efficiency of the above-mentioned equipment for the junction box is also insufficient. At the same time, the bottleneck time of the cooperation process of the above-mentioned equipment is relatively long, which greatly reduces the efficiency of the equipment in assembling the junction box. Therefore, a fully automatic assembly equipment for photovoltaic junction boxes is needed to solve the problems raised above. Summary of the Invention

The first rack is meshed and connected with a second rack through the transmission gear, and a junction box material guiding fixture is fixedly arranged on the side part of the second rack through a second L-shaped clamping plate;

[0012] The feeding device includes a first shaping die base for guiding materials.

A junction box guide groove is formed on one side of the first shaping die base facing the junction box loading bin, and a cover plate guide groove is formed on the side of the first shaping die base facing the cover plate loading bin. A limit slot is formed at the bottom of the rear end face of the junction box guide groove, and a spraying slot is formed near the middle of the rear end face of the first shaping die base. The junction box guide groove is used for feeding the junction box. The limit slot can lock and limit the fed junction box through a limit insertion plate. The cover plate guide groove can feed the sealing cover plate, and at the same time, the spraying slot can cooperate with the feeding guide plate to limit the bottom of the sealing cover plate.

[0013] Preferably, the transmission device includes a second synchronous pulley. One end of the second synchronous pulley is provided with a first transmission turntable, and a second transmission turntable is arranged at the other end of the second synchronous pulley. A first shifting shaft is arranged near the outside of the outer end face of the first transmission turntable, and a second shifting shaft is arranged near the outside of the outer end face of the second transmission turntable.

[0014] Preferably, the glue applying device includes a cylinder base. A three-axis cylinder is arranged at the center of the rear end face of the cylinder base, and a glue storage tank is arranged at the output end of the three-axis cylinder. A feeding conduit for docking is arranged at the side of the glue storage tank. A feeding guide plate is connected through the upper part of the front end face of the glue storage tank in a penetrating manner, and high-pressure atomizing nozzles are arranged on both the upper and lower parts of the inner end face of the feeding guide plate. A limit insertion plate is arranged at the lower part of the front end face of the glue storage tank. The feeding conduit can provide high-pressure glue inside the glue storage tank, which is convenient for subsequent introduction into the high-pressure atomizing nozzles through the feeding guide plate for glue application. The feeding guide plate and the limit insertion plate can also conveniently provide sufficient support for the junction box and the sealing cover plate introduced into the first shaping die base in the future. The cylinder base is a three-axis platform, which can provide sufficient guiding stability for the axial direction of the glue storage tank.

[0015] Preferably, the material guiding device includes a supporting base for guiding. At both ends inside the supporting base, there are rotationally clamped transmission clamping shafts. And at the inner end faces of the transmission clamping shafts, there are two groups of third synchronous belt pulleys. Between the two groups of third synchronous belt pulleys on the same side, they are meshed and connected through a trapezoidal tooth synchronous belt. And on the outer end face of the trapezoidal tooth synchronous belt, there are alignment ribs for limiting. Inside the two opposite alignment ribs, there are guiding jigs fixedly clamped at equal intervals. And on the upper end face of the supporting base, there are two supporting clamping plates for support. At the side end face of the supporting base, opposite to one of the transmission clamping shafts, there is a reduction motor. The two supporting clamping plates can guide and support the bottom of the guiding jig. When the processing device presses the junction box and the cover plate inside the guiding jig, the two supporting clamping plates can provide a sufficient supporting basis for the guiding jig. The mounting holes evenly distributed inside the alignment ribs can be square, which is convenient for subsequent installation and limitation of the guiding jig;

[0016] The guiding jig includes a second shaping die base. At the side end of the second shaping die base, there are two fixed guiding seats for guiding. At the center of the bottom of the fixed guiding seat, there is a positioning card slot. And at the center of the side end face of each fixed guiding seat, there is a plug connector. On the upper end face of the second shaping die base, there is a sealing card slot. And at equal intervals on the inner end face of the second shaping die base, there are alignment plug slots. Among them, the inner opening of the second shaping die base is chamfered, which is convenient for subsequent rapid introduction of the junction box and the cover plate. The multiple alignment plug slots can not only provide a limiting space for the heating of the subsequent heating rod, but also facilitate the subsequent airtightness detection when the junction box and the cover plate are adhesively docked, providing sufficient detection space. The fixed guiding seat can be slidably limited through the positioning card slot in cooperation with the supporting clamping plate, thereby providing a sufficient supporting basis for the subsequent pressing process of the pressing die base, the fixed seat and the connecting seat.

[0017] Preferably, the processing device includes a supporting sliding seat. At the center of the front end face of the supporting sliding seat, there is a guiding sliding rail. At the front end face of the supporting sliding seat, near the bottom of the guiding sliding rail, there is a spring guiding seat. And at the lower end face of the spring guiding seat, there is a pressing die base. At the lower end face of the supporting sliding seat, near the rear of the pressing die base, there is a heating device. At the lower end face of the supporting sliding seat, near the rear of the heating device, there is a sealing detection device. The pressing die base, the heating device and the sealing detection device are arranged side by side, which can make different processes proceed synchronously, maximizing the efficiency of subsequent assembly of the junction box and the cover plate. The spring guiding seat can provide sufficient elasticity for the pressing die base, so that the pressing die base can not only provide sufficient pressure when pressing the cover plate and the junction box, but also prevent damage caused by directly pressing the junction box and the cover plate;

[0018] The heating device includes a fixed seat. At the bottom of the inner end face of the fixed seat, a heating module is provided, and a heating block is fixedly arranged at the lower end face of the heating module. Heating rods are equidistantly arranged at the lower end face of the fixed seat. The sealing detection device includes a connecting seat. At the bottom of the inner end face of the connecting seat, a high-pressure air guiding module is provided, and air tightness detection modules are symmetrically arranged at the bottom end face of the connecting seat. A sealing sleeve is fixedly arranged at the center of the lower end face of the connecting seat. The sealing sleeve can seal the upper part of the second shaping mold base in all directions. At the same time, the high-pressure air guiding module can inject high-pressure air into the second shaping mold base. When there are problems with the air tightness between the junction box and the cover plate, the air tightness detection module can sense the air pressure change, thereby determining that the air tightness of the junction box and the cover plate is insufficient. When heating and curing the junction box and the cover plate after caulking, the heating block can perform all-round heating operations on the upper part of the junction box and the cover plate, and at the same time, the heating rods can perform all-round heating operations on the outside of the junction box and the cover plate.

[0019] Preferably, the first driving turntable is adapted to the fixed sliding seat through the first shifting shaft, thereby driving the first rack to perform reciprocating displacement in front of the limiting turntable. The first rack drives the second rack to perform synchronous reciprocating displacement in front of the limiting turntable through the transmission gear. When the first shifting shaft drives the first rack to perform reciprocating displacement through the fixed sliding seat, the first rack can drive the second rack to perform synchronous displacement through the transmission gear, which can facilitate the subsequent synchronous feeding of the junction box and the cover plate by the first rack and the second rack through the cover plate feeding fixture and the junction box feeding fixture, improving the efficiency of subsequent caulking and assembly.

[0020] Preferably, the junction box feeding fixture drives the junction box to be inserted into the first shaping mold base through the junction box guiding groove, and the cover plate feeding fixture drives the cover plate to be inserted into the first shaping mold base through the cover plate guiding groove. The feeding guide plate is slidably inserted into the first shaping mold base through the spraying slot, and the limiting insertion plate is slidably inserted into the bottom of the first shaping mold base through the limiting slot. The feeding guide plate can limit the bottom of the cover plate, and at the same time, the limiting insertion plate can limit the bottom of the junction box, facilitating sufficient space for the subsequent high-pressure atomizing nozzle to caulk the junction box and the cover plate. The structures of the junction box feeding fixture and the cover plate feeding fixture are similar, both in an L shape, which can perform closed feeding on the bottom openings of the junction box feeding bin and the cover plate feeding bin, and can also seal the outside of the first shaping mold base to improve the caulking effect. At the same time, baffles are provided at the tails of the junction box feeding fixture and the cover plate feeding fixture to prevent the subsequent synchronous feeding of multiple groups of junction boxes and cover plates.

[0021] Preferably, the second shaping die base is fixedly clamped to the outer end face of the alignment rib through the plug connector, and the fixed guide base is slidably clamped to the upper end face of the support base through the positioning card slot adapted to the support card plate, which can effectively improve the stability of the subsequent feeding and processing displacement of the second shaping die base above the support base. At the same time, it is convenient to assemble and position the second shaping die base subsequently, improving the convenience of subsequent assembly guidance.

[0022] Preferably, the second transmission turntable drives the support slide to reciprocate above the support seat through the second shift shaft adapted to the guide rail. The heating rod is slidably inserted into the second shaping die base through the alignment slot. The connecting seat is hermetically clamped to the second shaping die base through the sealing sleeve adapted to the sealing card slot. The sealing sleeve can hermetically seal the outside of the second shaping die base, thereby improving the airtightness of the combined junction box and cover plate by the subsequent airtightness detection module for accurate detection. When the second shift shaft rotates circumferentially, it can synchronously drive the support slide to move up and down, thereby cooperating with the assembly device to feed the junction box and cover plate, and can synchronously process and combine the junction box and cover plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. When the present invention assembles and processes the junction box and the cover plate, the servo motor can synchronously provide power for the fixed slide and the processing device through the transmission device, so that the fixed slide can synchronously introduce the junction box and the cover plate into the first shaping die base through the cover plate feeding fixture and the junction box feeding fixture. At the same time, the processing device can cooperate with the introduction of the cover plate feeding fixture and the junction box feeding fixture to assemble and press the junction box and the cover plate after gluing, effectively improving the automation degree and efficiency of the equipment for assembling the junction box and the cover plate.

[0025] 2. When the first transmission turntable and the second transmission turntable rotate one week, they can synchronously drive the cover plate feeding fixture, the junction box feeding fixture and the processing device to perform a reciprocating motion through the first shift shaft and the second shift shaft, so that the processing device can cooperate with the feeding of the cover plate feeding fixture and the junction box feeding fixture for non-stop processing, effectively reducing the bottleneck time of the equipment for processing, and also improving the speed of the equipment for assembling and processing the junction box and the cover plate.

[0026] 3. The present invention is a pipeline - type processing. The pressing die base, heating device, and sealing detection device responsible for different processes are respectively integrated in the lower part of the support sliding seat. This enables the pressing die base, heating device, and sealing detection device to synchronously perform multi - process processing on the workpiece that has been preliminarily assembled above the material guiding device, effectively improving the efficiency of the equipment for processing and detecting the junction box and cover plate, and at the same time enhancing the overall practical performance of the equipment.

A sealing slot 422 is formed on the upper end face of the second shaping die base 423, and a plurality of alignment slots 421 are equidistantly arranged on the inner end face of the second shaping die base 423. The inner opening of the second shaping die base 423 is chamfered, which is convenient for the subsequent quick introduction of the junction box 10 and the cover plate 11. The multiple alignment slots 421 can not only provide a limiting space for the heating of the heating rod 534, but also provide a sufficient detection space for the airtightness detection during the subsequent bonding and docking of the junction box 10 and the cover plate 11.

[0058] As Figure 12 and Figure 13 , the processing device 5 includes a support sliding seat 56. A guiding slide rail 51 is arranged at the center of the front end face of the support sliding seat 56. A spring guide seat 52 is arranged at the bottom of the front end face of the support sliding seat 56 near the guiding slide rail 51. The spring guide seat 52 can provide sufficient elastic force for the pressing die base 55, so that the pressing die base 55 can not only provide sufficient pressure when pressing the cover plate 11 and the junction box 10, but also prevent damage to the junction box 10 and the cover plate 11 during direct pressing. A pressing die base 55 is arranged at the lower end face of the spring guide seat 52. A heating device 53 is arranged at the lower end face of the support sliding seat 56 near the rear of the pressing die base 55. A sealing detection device 54 is arranged at the lower end face of the support sliding seat 56 near the rear of the heating device 53. The pressing die base 55, the heating device 53 and the sealing detection device 54 are arranged side by side, which can make different processes proceed synchronously, and maximize the efficiency of the subsequent assembly of the junction box 10 and the cover plate 11;

[0059] As Figure 14 , the heating device 53 includes a fixed seat 531. A heating module 532 is arranged at the bottom of the inner end face of the fixed seat 531, and a heating block 533 is fixedly arranged at the lower end face of the heating module 532. Heating rods 534 are equidistantly arranged at the lower end face of the fixed seat 531. When heating and curing the junction box 10 and the cover plate 11 after gluing, the heating block 533 can perform all-round heating operations on the upper parts of the junction box 10 and the cover plate 11, and at the same time, the heating rods 534 can perform all-round heating operations on the outsides of the junction box 10 and the cover plate 11;

[0060] As Figure 15, the seal detection device 54 includes a connecting seat 541. At the bottom of the inner end face of the connecting seat 541, a high-pressure air guiding module 542 is provided. And symmetrically arranged at the bottom end face of the connecting seat 541 are airtightness detection modules 543. At the center of the lower end face of the connecting seat 541, a sealing sleeve 544 is fixedly provided. The sealing sleeve 544 can seal the upper part of the second shaping die base 423 in all directions. At the same time, the high-pressure air guiding module 542 can inject high-pressure air into the second shaping die base 423. When there are problems with the airtightness of the junction box 10 and the cover plate 11, the airtightness detection modules 543 can sense the air pressure change, and then determine that the airtightness of the junction box 10 and the cover plate 11 is insufficient.

[0061] As Figure 3 and Figure 7 , the first transmission turntable 241 is adapted to the fixed slide 26 through the first shifting shaft 242, thereby driving the first rack 27 to perform reciprocating displacement in front of the limit turntable 213. The first rack 27 drives the second rack 212 to perform synchronous reciprocating displacement in front of the limit turntable 213 through the transmission gear 211. When the first shifting shaft 242 drives the first rack 27 to reciprocate through the fixed slide 26, the first rack 27 can drive the second rack 212 to synchronously displace through the transmission gear 211, which can facilitate the subsequent first rack 27 and the second rack 212 to synchronously drive the junction box 10 and the cover plate 11 to be fed synchronously through the cover plate feeding fixture 28 and the junction box feeding fixture 215, improving the efficiency of subsequent gluing and assembly.

[0062] As Figure 3 and Figure 6 , the junction box feeding fixture 215 drives the junction box 10 to be inserted into the first shaping die base 237 through the junction box guide groove 235. The cover plate feeding fixture 28 drives the cover plate 11 to be inserted into the first shaping die base 237 through the cover plate guide groove 233. The structures of the junction box feeding fixture 215 and the cover plate feeding fixture 28 are similar, both in an L shape, which can perform closed feeding on the bottom openings of the junction box feeding bin 231 and the cover plate feeding bin 232, and can also seal the outside of the first shaping die base 237 to improve the gluing effect. At the same time, baffles are provided at the tails of the junction box feeding fixture 215 and the cover plate feeding fixture 28 to prevent subsequent multiple groups of junction boxes 10 and cover plates 11 from being fed synchronously. The feeding guide plate 35 is slidably inserted into the first shaping die base 237 through the spraying slot 236, and the limit insertion plate 36 is slidably inserted into the bottom of the first shaping die base 237 through the limit slot 234. The feeding guide plate 35 can limit the bottom of the cover plate 11, and at the same time, the limit insertion plate 36 can limit the bottom of the junction box 10, facilitating sufficient space for the subsequent high-pressure atomizing nozzle 34 to apply glue to the junction box 10 and the cover plate 11.

[0063] As Figure 9 and Figure 11The second shaping die base 423 is fixedly clamped to the outer end face of the alignment rib 41 through the insertion joint 425, which facilitates the subsequent assembly and positioning of the second shaping die base 423 and improves the convenience of subsequent assembly guidance. The fixed guide base 424 is slidably clamped to the upper end face of the support base 47 through the positioning slot 426 adapted to the support card plate 43, which can effectively improve the stability of the subsequent feeding and processing displacement of the second shaping die base 423 above the support base 47.

[0064] As Figure 11 and Figure 13 shown, the second transmission turntable 244 drives the support sliding seat 56 to reciprocate above the support card holder 6 through the second shifting shaft 243 adapted to the guiding slide rail 51. When the second shifting shaft 243 rotates in a circle, it can synchronously drive the support sliding seat 56 to move up and down, and then cooperate with the assembly device 2 to feed the junction box 10 and the cover plate 11, and can synchronously process and combine the junction box 10 and the cover plate 11. The heating rod 534 is slidably inserted into the second shaping die base 423 through the alignment slot 421. The connecting seat 541 is hermetically clamped to the second shaping die base 423 through the sealing sleeve 544 adapted to the sealing slot 422. The sealing sleeve 544 can perform all-round sealing on the outside of the second shaping die base 423, thereby improving the airtightness of the combined junction box 10 and cover plate 11 by the subsequent airtightness detection module 543 and performing accurate detection.

[0065] Working principle: Before use, as Figure 1 and Figure 4 shown, the staff can respectively introduce the junction box 10 and the cover plate 11 to be assembled into the junction box loading bin 231 and the cover plate loading bin 232, which facilitates the subsequent rapid and continuous assembly operation of the batch of junction box loading bin 231 and cover plate loading bin 232. In the initial state of assembling the accessories, the first rack 27 and the second rack 212 are in the initial position, and at the same time, the processing device 5 is at the lowest processing position. At the same time, the feeding guide plate 35 and the limiting insertion plate 36 inside the gluing device 3 are inserted into the feeding conduit 37, which facilitates the subsequent guiding and limiting of the junction box 10 and the cover plate 11. Subsequently, the staff can start the servo motor 22 through the external control device. At this time, the servo motor 22 can drive the first synchronous pulley 25 to rotate. When the first synchronous pulley 25 rotates, the first synchronous pulley 25 can drive the second synchronous pulley 245 to rotate synchronously through the arc-tooth synchronous belt 210. When the second synchronous pulley 245 rotates, the second synchronous pulley 245 can synchronously drive the first transmission turntable 241 and the second transmission turntable 244 to rotate in a circle. The first transmission turntable 241 can synchronously drive the first shifting shaft 242 to rotate in a circle, and the second transmission turntable 244 can drive the second shifting shaft 243 to rotate in a circle. As Figure 3, when the first dial shaft 242 rotates, the first dial shaft 242 can synchronously drive the fixed slide 26 to perform a cyclic reciprocating displacement at the front part of the limit swivel base 213. At this time, the fixed slide 26 can synchronously drive the first rack 27 at the bottom to perform a reciprocating displacement. When the first rack 27 displaces, it can synchronously drive the second rack 212 at the bottom to perform a reciprocating displacement through the transmission gear 211. As shown in Figure 3 , Figure 5 and Figure 6 , at this time, 217 can drive the cover plate feeding fixture 28 to displace towards the opening of the cover plate guide groove 233 through the first L-shaped clamping plate 29. At the same time, the second rack 212 can drive the junction box feeding fixture 215 to displace towards the opening of the junction box guide groove 235 through the second L-shaped clamping plate 214. When the junction box feeding fixture 215 and the cover plate feeding fixture 28 perform centripetal displacement, the junction box 10 and the cover plate 11 at the bottom of the junction box feeding bin 231 and the cover plate feeding bin 232 can, under the synchronous limit of the junction box feeding fixture 215 and the cover plate feeding fixture 28, together displace towards the inside of the first shaping die base 237. When the above-mentioned junction box feeding fixture 215 and cover plate feeding fixture 28 are driven by the transmission device 24 to perform centripetal displacement, since the first dial shaft 242 and the second dial shaft 243 are arranged with a 90-degree deflection, when the first dial shaft 242 displaces from one horizontal side to the other horizontal side, the second dial shaft 243 can displace from the lowest position to the highest position. That is, when the junction box feeding fixture 215 and the cover plate feeding fixture 28 drive the junction box 10 and the cover plate 11 to be inserted into the first shaping die base 237 through the limit of the junction box guide groove 235 and the cover plate guide groove 233, at this time, the processing device 5 is displaced to the highest position under the drive of the second dial shaft 243. As shown in Figure 6 , when the above-mentioned junction box 10 and cover plate 11 are fed into the feeding conduit 37, at this time, the junction box feeding fixture 215 can drive the internal junction box 10 to be limited to the bottom of the first shaping die base 237 through the junction box guide groove 235. At the same time, the cover plate feeding fixture 28 can drive the cover plate 11 to be limited to the middle of the first shaping die base 237 through the cover plate guide groove 233. That is, at this time, the first shaping die base 237 is completely closed. At the same time, the bottom of the cover plate 11 is directly opposite to the high-pressure atomizing nozzle 34, and the top of the junction box 10 is directly opposite to the high-pressure atomizing nozzle 34. At this time, under the supply of the high-pressure glue in the glue liquid storage tank 32, the high-pressure atomizing nozzle 34 can perform glue application operations on the bottom of the cover plate 11 and the top of the junction box 10. After the glue application is completed, as shown in Figure 1 , Figure 4 and Figure 8, at this time, the three-axis cylinder 31 can be retracted, and then drive the feeding guide plate 35 and the limit insertion plate 36 to retract synchronously, thereby releasing the bottom limit of the feeding guide plate 35 on the sealing cover plate 11 and simultaneously releasing the bottom limit of the limit insertion plate 36 on the junction box 10. At this time, the junction box 10 and the sealing cover plate 11 after gluing can directly fall into the second shaping die base 423 under the guidance of the first shaping die base 237 and the material guiding chute 7. At this time, the junction box 10 and the sealing cover plate 11 after gluing are closely attached to each other. At this time, the above-mentioned first shifting shaft 242 continues to rotate circumferentially. At this time, the first shifting shaft 242 can drive the junction box material guiding fixture 215 and the cover plate material guiding fixture 28 to perform centrifugal displacement synchronously through the fixed sliding seat 26 and the transmission gear 211. At the same time, the second shifting shaft 243 can drive the support sliding seat 56 to move downward from top to bottom through the guiding slide rail 51. When the first shifting shaft 242 continues to move to the initial position, at this time, the second shifting shaft 243 can drive the spring guide seat 52 and the pressing die base 55 to move to the lowest working position through the guiding slide rail 51. At this time, the pressing die base 55 can stably and elastically press the junction box 10 and the sealing cover plate 11 after gluing. At the same time, the heating rod 534 can be inserted into the alignment slot 421 inside the previous group of second shaping die bases 423. Subsequently, the heating module 532 can heat the junction box 10 and the sealing cover plate 11 after pressing through the heating block 533 and the heating rod 534 to improve the stability of the adhesion between the junction box 10 and the sealing cover plate 11. At the same time, the frontmost connecting seat 541 can be hermetically inserted into the sealing slot 422 on the upper part of the second shaping die base 423 through the sealing sleeve 544. At the same time, the high-pressure air guiding module 542 can inject high-pressure gas into the second shaping die base 423. At the same time, the airtightness detection module 543 can sense the pressure inside the second shaping die base 423, and then determine the airtightness of the assembled junction box 10 and the sealing cover plate 11. When the processing device 5 moves upward again, at this time, the reduction motor 46 can drive the bottom of the positioning material guiding chute 7 of the next group of second shaping die bases 423 synchronously through the third synchronous pulley 44 and the trapezoidal tooth synchronous belt 48, facilitating the processing of the next group of junction boxes 10 and sealing cover plates 11.
