[0002] Photovoltaic modules are solar cell modules. Since the output voltage of single solar cells is low and the electrodes of unpackaged cells are easily detached due to environmental influences, a certain number of single cells must be sealed into photovoltaic modules in series and parallel to avoid corrosion of the cell electrodes and interconnections.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0029] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0030] like Figure 1-Figure 5 As shown, the present invention provides photovoltaic module welding equipment, comprising: a welding equipment body, which includes a base 1, a welding table 6, a movable welding mechanism, and an exhaust gas absorption assembly. A support box 2 is mounted on the base 1, the movable welding mechanism is mounted on the base 1, and an exhaust gas absorption assembly is mounted on one side of the base 1. The welding table 6 is mounted on the support box 2. The welding table 6 provides a support position for the welding of photovoltaic modules. When welding photovoltaic modules, the photovoltaic modules are placed on top of the welding table 6. The base 1 is used to support the movable welding mechanism from the bottom and also provides a mounting position for the exhaust gas absorption assembly. The exhaust gas absorption assembly is used to absorb and purify the exhaust gas generated by the welding equipment, so that the absorbed and discharged exhaust gas is clean gas and does not affect the working environment.

[0031] Furthermore, some embodiments of the present invention provide a specific structure of the above-mentioned exhaust gas absorption component, wherein the exhaust gas absorption component of this structure includes an exhaust pump 11, a transmission pipe 12, a connecting pipe 13, a corrugated hose 21, an annular suction shell 33, an suction hole 34, and a purification component, wherein the exhaust pump 11 is configured to be installed on the support plate 10 of the base 1, the transmission pipe 12 is connected to the input end of the exhaust pump 11, the corrugated hose 21 is configured to be installed at one end of the transmission pipe 12, an annular suction shell 33 is configured to be installed at one end of the corrugated hose 21, a plurality of suction holes 34 are opened at the bottom of the annular suction shell 33, the connecting pipe 13 is configured to be installed at the output end of the exhaust pump 11, a purification component is configured to be installed at one end of the connecting pipe 13, and the purification component is fixed on the top of the support plate 10.

[0032] When the vacuum pump 11 is started, its input end generates suction force for the inhaled air. Since the input end of the vacuum pump 11 is connected to the annular suction shell 33 through the transmission pipe 12 and the corrugated hose 21, the annular suction shell 33 absorbs the exhaust gas generated during welding through the suction hole 34 at the bottom. Since the annular suction shell 33 used for absorbing the exhaust gas generated during welding is installed on the outside of the welding end of the welding head 32, the exhaust gas generated by the welding head 32 during welding can be directly absorbed by the annular suction shell 33, reducing the pollution caused by the exhaust gas drifting into the environment, achieving the maximum absorption of the generated exhaust gas, and making the exhaust gas absorption effect of the exhaust gas absorption component better. The absorbed exhaust gas is discharged through the connecting pipe 13 at the output end, so that the exhaust gas enters the interior of the purification shell 14 through the connecting pipe 13, so that the absorbed and discharged exhaust gas is clean gas, which will not affect the working environment.

[0033] Furthermore, some embodiments of the present invention provide a specific structure of the above-mentioned purification component, where the purification component of the structure includes a purification shell 14, a first purification layer 16, a second purification layer 17, a third purification layer 18 and an exhaust net 15. The purification shell 14 is configured to be installed on the top of the support plate 10, and the first purification layer 16, the second purification layer 17 and the third purification layer 18 are arranged and installed inside the purification shell 14. The exhaust net 15 is configured to be installed inside one side of the purification shell 14. When in use, the exhaust gas generated by welding passes through the first purification layer 16, the second purification layer 17 and the third purification layer 18 inside, respectively, and the exhaust gas is discharged by the first purification layer 16, the second purification layer 17 and the third purification layer 18 in the purification shell 14. The third purification layer 18 purifies and filters the exhaust gas. The first purification layer 16 is a HEPA filter, and the second purification layer 17 is a honeycomb activated carbon layer. The honeycomb structure increases the contact area, prolongs the gas residence time, and adsorbs VOCs, ozone and odor molecules (such as formaldehyde and benzene series) through the microporous structure. The third purification layer 18 is potassium iodide impregnated activated carbon, which can purify the ozone in the exhaust gas. After passing through the first purification layer 16, the second purification layer 17 and the third purification layer 18, the exhaust gas is discharged to the outside through the exhaust net 15, so that the absorbed and discharged exhaust gas is clean gas, which will not affect the working environment. At the same time, the corrugated hose 21 is extensible and can be telescopic, with higher flexibility.

[0034] Furthermore, in some embodiments of the present invention, a disassembly door 3 is provided on the front of the support box 2 by bolts, a control box 4 is provided on one side of the support box 2, a fixing seat 5 is provided on the top of the support box 2, a welding table 6 is provided on the top of the fixing seat 5, mounting plates 7 are symmetrically provided on the tops of both sides of the fixing seat 5, a first pneumatic cylinder 8 is provided on one side of the mounting plate 7, a clamping plate 9 is provided on the output end of the first pneumatic cylinder 8, a support rod 19 is provided on the top of the back side of the fixing seat 5, a fixing ring 20 is provided on the top of the support rod 19, and the fixing ring 20 is provided on the outside of one end of the transmission pipe 12. Among them, the interior of the support box 2 is a welding system, a drive system, and a pneumatic system (not shown). At the same time, the support box 2 also provides a location for the installation of the fixing seat 5. The front of the support box 2 can be opened by disassembling the door 3, which is convenient for maintenance of the interior of the support box 2. The control box 4 is used to control the use of the main body of the welding equipment. The photovoltaic component is placed on the top of the welding table 6. The air pressure energy is converted into kinetic energy through the first pneumatic cylinder 8, which drives the clamping plate 9 at the output end to move toward each other, thereby clamping the photovoltaic component located on the top of the welding table 6 stably to avoid movement during welding and causing the welding to be offset. The top of the support rod 19 is connected to the transmission pipe 12 through the fixing ring 20, which is used to support the transmission pipe 12. The transmission pipe 12 is a stainless steel pipe.

[0035] Furthermore, some embodiments of the present invention provide a specific structure of the above-mentioned movable welding mechanism, wherein the movable welding mechanism of this structure includes a driving member and a welding part, wherein the driving member is located behind the support box 2, and the welding part is arranged on the driving member, and the above-mentioned welding part includes a second pneumatic cylinder, a connecting platform 31, and a welding head 32, the second pneumatic cylinder 29 is arranged on the driving member, the telescopic end of the second pneumatic cylinder 29 is configured to be installed with a frame 30, the front of the frame 30 is configured to be installed with a connecting platform 31, and one end of the connecting platform 31 is penetrated and installed with a welding head 32, the welding head 32 is located above the welding platform 6, and the outer side of the welding end of the welding head 32 is connected to the annular air intake shell 33.

[0036] The above-mentioned driving component includes a driving box 22, which is located at the rear of the supporting box 2. A forward and reverse motor 28 is arranged on one side of the driving box 22. A through groove 23 is opened on the top of the driving box 22. The internal rotation of the driving box 22 is equipped with a screw 24 connected to the output end of the forward and reverse motor 28. The outer spiral of the screw 24 is equipped with a transmission block 25. The top of the transmission block 25 is equipped with a connecting block 26 that slides with the through groove 23. The top of the connecting block 26 is equipped with a moving platform 27. The moving platform 27 is slidably arranged on the top of the driving box 22.

[0037] Among them, the above-mentioned drive box 22 provides an installation position for the structure that drives the welding head 32. When the welding head 32 needs to move horizontally, the control box 4 is used to turn on the forward and reverse motors 28. After power is turned on, the forward and reverse motors 28 drive the output end screw 24 to rotate. Since the transmission block 25 passes through the through groove 23 through the connecting block 26 and is connected to the movable platform 27, the transmission block 25 is limited and can move horizontally on the outside of the screw 24, thereby driving the connected movable platform 27 to move. The movable platform 27 provides an installation position for the second pneumatic cylinder 29. The second pneumatic cylinder 29 converts the air pressure energy into kinetic energy to drive the output end bracket 30 to move up and down, thereby adjusting the use height of the welding head 32, so that the welding head 32 can move both horizontally and vertically, making the welding head 32 more flexible, thereby facilitating the welding processing of photovoltaic modules.

[0038] like Figure 6-Figure 8As shown, further, in some embodiments of the present invention, the welding equipment body also includes a swing module 40, where the swing module 40 of this structure includes a swing seat 41 and two swing frames 42, wherein the swing seat 41 is configured to be installed at the bottom of the outer end of the frame 30, and the swing seat 41 has a swing hole 411, and the two swing frames 42 are configured to be installed at the bottom of the swing seat 41 and are located on both sides of the swing hole 411, the welding head 32 passes through the swing hole 411, and the two swing frames 42 wrap and contact the welding head 32. When the operator adjusts the distance between the welding head 32 and the photovoltaic component through the second pneumatic cylinder 29, if the direct distance between the two is adjusted too small, the welding head 32 will touch the photovoltaic component. The swing module 40 provided can facilitate the swinging and resetting of the welding head 32, and then the operator continues to adjust it; in addition, during the welding process, the two swing frames 42 wrap the welding head 32, which will also make the welding head 32 more stable, reduce the drift range of the welding arc, and thereby improve the welding quality of the photovoltaic component.

[0039] Furthermore, some embodiments of the present invention provide a specific structure of the above-mentioned swing support frame 42, where the swing support frame 42 of this structure includes an intermediate support block 43, an intermediate rocker arm 44, an intermediate C-shaped covering plate 45, two side support blocks 46, two side linkage members 47 and an intermediate reset member 48, wherein the intermediate support block 43 is configured and installed on both sides of the two side support blocks 46, the intermediate support block 43 and the two side support blocks 46 are connected by two connecting plates 431, the intermediate rocker arm 44 is configured and installed at the bottom of the intermediate support block 43, the two side linkage members 47 are respectively configured and installed at both ends of the intermediate rocker arm 44, the intermediate C-shaped covering plate 45 is configured and installed between the two side linkage members 47, and wraps the contact welding joint 32, and at the same time, the side linkage member 47 is movably connected to the side support block 46, and the intermediate reset member 48 is configured and installed between the two side support blocks 46 and is respectively connected to the two side linkage members 47. When the welding head 32 swings, it will drive one end of the middle C-shaped wrapping plate 45 close to the middle support block 43, while the other end will move away from the middle support block 43. At this time, it is connected to the two side linkage parts 47 through the middle reset part 48, so that the above-mentioned swinging process is carried out steadily and slowly, rather than in a large range. In other words, the swinging range of the welding head 32 is very small, thereby reducing the welding arc drift range of the welding head 32, thereby improving the welding quality of the photovoltaic module.

[0040] Furthermore, some embodiments of the present invention provide a specific structure of the above-mentioned side linkage member 47, wherein the side linkage member 47 of the structure includes a first linkage arm 471, a second linkage arm 472, and a third linkage arm 473, wherein one end of the first linkage arm 471 is connected to the end of the middle swing link 44, and the other end of the first linkage arm 471 is connected to one end of the second linkage arm 472, so that the side linkage member 47 is V-shaped, the other end of the second linkage arm 472 is connected to the middle C-shaped package plate 45, one end of the third linkage arm 473 is connected to the middle part of the first linkage arm 471, and the other end is provided with a U-shaped clamping block 474, which is provided in the side opening 461 of the side support block 46, and is connected to the middle reset member 48. A side fixing block 462 is provided in the side opening 461 to prevent the U-shaped clamping block 474 from moving too much.

[0041] When one end of the middle C-shaped wrapping plate 45 drives the second linkage arm 472 to move, the second linkage arm 472 drives the first linkage arm 471 to rotate with the end of the middle rocker 44 as the axis, so that one end of the middle C-shaped wrapping plate 45 is close to the middle support block 43. At the same time, the first linkage arm 471 also drives the third linkage arm 473 to move in the side opening 461 and approach the side fixing block 462. Through the above-mentioned side linkage member 47, the swing process of the welding head 32 is carried out steadily and slowly, rather than drastically, so as to improve the welding quality of the photovoltaic module.

[0042] Furthermore, some embodiments of the present invention provide a specific structure of the intermediate reset member 48. Here, the intermediate reset member 48 comprises a reset spring 481, a shaft 482, and a reset block 483. The shaft 482 is mounted on the bottom of the swing support seat 41, and the reset block 483 is mounted on the bottom of the shaft 482. The reset spring 481 is sleeved on the shaft 482 and connected between the reset block 483 and the swing support seat 41. Guide arm mechanisms 49 are connected to both sides of the reset block 483, and the guide arm mechanisms 49 are connected to the side linkage member 47. During the swinging process of the welding head 32, the two third linkage arms 473 of the side linkage member 47 produce opposite movements, thereby causing the two guide arm mechanisms 49 of the reset member 48 to move in opposite directions. During this process, the reset block 483 also swings back and forth on the shaft 482. The reset spring 481 has the elastic force to offset the reciprocating swing of the reset block 483, thereby ensuring a steady and slow swinging process rather than a large swing, thereby improving the welding quality of the photovoltaic module.

[0043] Furthermore, some embodiments of the present invention provide a specific structure of the above-mentioned guide arm mechanism 49, wherein the guide arm mechanism 49 of the structure includes a guide arm body 491, a first guide plate 492, a telescopic member 493, and a second guide plate 494, wherein one end of the guide arm body 491 is connected to the reset block 483, the first guide plate 492 is configured to be installed at the other end of the guide arm body 491, the telescopic member 493 is configured to be installed on the first guide plate 492, and the second guide plate 494 is configured to be installed on the telescopic member 493 and connected to the side linkage member 47. The U-shaped block 474 is connected, so when the U-shaped block 474 moves in the side opening 461, it can drive the second guide plate 494 to move synchronously, and then transmit it to the guide arm body 491 through the telescopic member 493 and the first guide plate 492, and drive the reset block 483 to swing through the guide arm body 491. Through the setting of the above-mentioned first guide plate 492, telescopic member 493, and second guide plate 494, the swinging process is also carried out steadily and slowly, rather than in a large range, thereby improving the welding quality of the photovoltaic components.
