Description

Technical Field

[0001] The utility model belongs to the field of sealing glue guns, in particular to a sealing glue gun for a photovoltaic component junction box. Background Art

[0002] Solar cells are also called "photovoltaic cells" or "solar chips". They are a kind of semiconductor sheets that convert light energy into electrical energy. At the same time, solar photovoltaic panels are mainly composed of solar cells, photovoltaic glass, EVA film, photovoltaic backplane, solar aluminum frame and junction box. At the same time, silicone is needed to bond the junction box to the back of the photovoltaic panel. When applying the glue, a glue gun will be used for auxiliary operation. The sealant glue gun is a tool for applying sealant. By using a glue gun, the construction efficiency can be improved and the waste of sealant can be reduced.

[0003] According to the Chinese patent application No.: 202321935485.4, a switch cabinet flame retardant sealant glue gun is disclosed, which relates to the field of glue guns, including a glue gun body, a gun body adjustment mechanism and a glue pushing mechanism. The glue gun body includes an upper gun body and a lower gun body hinged up and down, and corresponding telescopic connecting parts are provided on the upper gun body and the lower gun body. By setting the glue gun body, the gun body adjustment mechanism and the glue pushing mechanism, the sealing airbag is ventilated through the bellows to inflate the sealing airbag, so that the sealing airbag can be used in conjunction with hoses of different apertures. After the sealing airbag is fully inflated, the solenoid valve is closed, and the gas generated by the air pump extends the bellows to push the sealing airbag to move, and the sealant in the hose is pushed out for glue application. The screw can also be rotated. Under the cooperation of the screw and the spiral tube, the telescopic connecting part is pushed to expand and contract, and the length of the glue gun body is adjusted, so that hoses of different lengths can be equipped conveniently, so that the glue gun can be used in conjunction with hoses of different sizes.

[0004] The comparative case effectively solves the problem that the glue gun in the prior art cannot be equipped with different hoses, which reduces the versatility of the glue gun. It has the advantage of being able to be equipped with different hoses, but in actual use, most basic glue guns have a manual control function. The operator can control the flow of glue by squeezing the trigger. The force and duration of the squeeze will directly affect the flow rate of the glue, resulting in uneven or excessive amount of glue adhering to the target object.

[0005] In summary, the utility model provides a photovoltaic module junction box sealing glue gun to solve the above problems. Utility Model Content

[0018] like Figure 1-4As shown, it is the first embodiment of the utility model, which provides a photovoltaic module junction box sealing glue gun, including a gun body 1, a glue storage tube 2 is fixedly connected to the front end of the gun body 1, the glue storage tube 2 is used to place the glue tube, the front end of the glue storage tube 2 is connected to a glue outlet tube 3, the glue outlet tube 3 is used to guide the sealant, the inner cavity of the gun body 1 is provided with a glue pushing mechanism 4, the glue pushing mechanism 4 includes a transmission component 41 and an extrusion component 42, the glue pushing mechanism 4 is used to push the sealant, the surface of the gun body 1 is installed with a control component 5, the control component 5 is used to control the amount of sealant glue, the bottom of the gun body 1 is provided with a power supply 6, the power supply 6 is used to provide electric energy to the glue pushing mechanism 4 and the control component 5, the transmission component 41 includes a servo motor 411, an active synchronous wheel 412 and a driven synchronous wheel 413, the active synchronous wheel 412 and the driven synchronous wheel 413 are connected by a synchronous belt transmission, and the servo motor 411 is connected to the gun body 1 is fixedly connected to the inner wall of the servo motor 411, the output shaft of the servo motor 411 is transmission-connected to the active synchronous wheel 412, the extrusion component 42 includes a piston 421, a screw rod 422 and a threaded hole 423, the threaded hole 423 is arranged on the surface of the driven synchronous wheel 413, one end of the screw rod 422 passes through the threaded hole 423 and is fixedly connected to the piston 421, and is threadedly connected to the inner cavity of the threaded hole 423, the other end of the screw rod 422 passes through the outside of the gun body 1, the control component 5 includes a PLC controller 501, a flow sensor 502 and a trigger 503, the PLC controller 501 and the trigger 503 are both installed on the surface of the gun body 1, the trigger 503 is installed on the surface of the rubber outlet hose 3, the output ends of the flow sensor 502 and the trigger 503 are both electrically connected to the input end of the PLC controller 501, and the output end of the PLC controller 501 is electrically connected to the input end of the servo motor 411.

[0019] like Figure 1-4As shown, the sealant hose is fixed in the inner cavity of the glue storage tube 2, and the glue application amount is set by the control component 5. The power supply 6 provides power to the glue pushing mechanism 4 and the control component 5 to enable them to operate normally. The power supply 6 can select a 12V lithium battery. The transmission component 41 drives the extrusion component 42 to move, so that the extrusion component 42 can push the colloid through the glue outlet tube 3 to the back of the photovoltaic panel for bonding to the junction box, thereby enabling the gluing operation to reduce the waste of sealant. The output shaft of the servo motor 411 rotates forward to drive the active synchronous wheel 412 to rotate. When the active synchronous wheel 412 rotates, it drives the driven synchronous wheel 413 to rotate through the synchronous belt. When the driven synchronous wheel 413 rotates, it drives the screw rod 422 to move toward the inner cavity of the gun body 1 through the threaded hole 423, so that the screw rod 422 can push the piston 421 to move. When the piston 421 moves, it squeezes the sealant, so that the sealant can be applied to the photovoltaic panel through the glue outlet tube 3. The back side of the gun body 1 is bonded to the junction box, the output shaft of the active synchronous wheel 412 is reversed to drive the screw rod 422 to move to the outside of the gun body 1, so that the piston 421 can be reset, and the flow sensor 502 can detect the flow rate of the sealant in the inner cavity of the glue outlet pipe 3.

The flow sensor 502 sends the detected flow to the PLC controller 501, so that the PLC controller 501 can adjust the speed of the servo motor 411. When the flow sensor 502 detects that the glue output is lower than the set value, the PLC controller can increase the speed of the servo motor 411 to increase the glue output. Otherwise, the speed of the servo motor 411 can be reduced, thereby reducing the glue output, and then the glue output of the sealant can be adjusted.

[0020] When in use, first fix the sealant hose in the inner cavity of the glue storage tube 2, set the glue application amount through the PLC controller 501, detect the glue output amount through the flow sensor 502, then align the glue output hose 3 with the glue application position of the photovoltaic panel, press the trigger 503, the trigger 503 will cooperate with the PLC controller 501, so that the PLC controller 501 starts the servo motor 411, the output shaft of the servo motor 411 rotates forward to drive the active synchronous wheel 412 to rotate, and when the active synchronous wheel 412 rotates, it drives the driven synchronous wheel 413 to rotate through the synchronous belt, and when the driven synchronous wheel 413 rotates, it drives the driven synchronous wheel 413 to rotate through the synchronous belt. The threaded hole 423 drives the screw rod 422 to move toward the inner cavity of the gun body 1, so that the screw rod 422 can push the piston 421 to move. The piston 421 squeezes the sealant when it moves, so that the sealant can be applied to the back of the photovoltaic panel through the glue outlet pipe 3 to bond the junction box. The flow sensor 502 detects the flow rate of the sealant in the inner cavity of the glue outlet pipe 3, and sends the detected flow rate to the PLC controller 501. According to the flow value, the PLC controller 501 can adaptively adjust the rotation speed of the servo motor 411 to make the glue output reach the set value, thereby adjusting the glue output of the sealant.
