Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaic equipment, and in particular to an automatic assembly machine for a junction box and a photovoltaic panel and a working method. Background Art

[0002] When producing solar photovoltaic panels, after the silicon wafer array is arranged on the glass plate, multiple arrayed silicon wafers need to be connected through bus bars, and then the junction box needs to be fixed on the photovoltaic panel. At the same time, the lead end of the bus bar needs to be reliably connected to the junction box in order to achieve electrical connection with the control equipment, etc.

[0003] The lead end of the busbar needs to stand upright when connected to the junction box, but it is inconvenient to transport and store the lead end upright. Therefore, in order to save space and facilitate transportation, the lead end is usually bent into a lying posture before the busbar enters the machine where the busbar is connected to the junction box. In order to prevent the lead end from being pressed too tightly against the busbar when bending and to protect the surface that needs to be welded in the subsequent process, a layer of high-temperature tape or transparent tape (hereinafter referred to as tape) is attached to the busbar before bending. The installation process of the junction box is as follows: first, you need to tear off the tape and shape the bent lead end to make it upright. Next, fix the junction box through the lead end on the glass plate, and finally weld the lead to the junction box to complete the installation of the junction box. Connect the connector of the junction box to the external circuit, and the junction box will be able to conduct the current generated by the solar cell. The original installation of junction boxes on solar photovoltaic panels mainly relies on manual work. The efficiency of manual installation is low and it is difficult to meet the requirements of mass and efficient production. Therefore, someone invented an automatic junction box installation machine. The patent document with the authorization announcement number CN218123931U discloses an automatic junction box installation machine, including a conveying part and an operating part, wherein: the conveying path of the conveying part is provided with a positioning station, a lead shaping station, a junction box installation station and a welding station, the conveying part conveys the battery string components step by step, and each step conveys a junction box installation position from the current operating station to the next operating station; the operating part includes a positioning mechanism, a lead shaping mechanism, a junction box installation mechanism and a welding mechanism, wherein: the positioning mechanism is located above the positioning station, and is used to position the junction box installation position; the lead shaping mechanism is located above the lead shaping station, and is used to tear off the tape on the junction box installation position and shape the lead; the junction box installation mechanism is located above the junction box installation position, and is used to install the junction box on the junction box installation position; the welding mechanism is located above the welding station, and is used to perform welding on the junction box installation position. The automatic installation of the junction box is realized, and the installation efficiency of the junction box is improved.

[0004] However, this scheme is for a structure in which the first junction box installation position, the second junction box installation position and the third junction box installation position are arranged along the conveying direction. Then, at each workstation, only one junction box can be processed at a time, and the efficiency is still low. Moreover, this scheme can only process junction boxes of the same specification. Usually, the structure of the junction box in the middle position is inconsistent with that of the junction boxes at both ends. The junction boxes at both ends have connecting wires, while the junction box in the middle does not have connecting wires. Therefore, it is necessary to design an automatic installation machine for solar photovoltaic panels that can be suitable for installing different junction boxes and can process the first junction box installation position, the second junction box installation position and the third junction box installation position that are perpendicular to the conveying direction at the same time, so as to further improve the installation efficiency.

The function of the machine is to install the junction box at the lead end of the busbar so as to achieve electrical connection with the control equipment, etc. Of course, the busbar straightening, glue tearing and shaping device 1, the photovoltaic panel gluing device 2, the junction box preparation and loading device 3, the busbar bending device 4 and the busbar pressing and welding device 5 are not necessarily all arranged on one frame, and the above devices can be separate and assembled into an assembly line according to the production process.

[0051] Figure 2 1 shows a bus bar 100 and two different types of junction boxes arranged on a photovoltaic panel. The figure also shows the state of the lead end 101 of the bus bar 100 before entering the machine processing of the present invention. Considering that the photovoltaic panel needs to save space and protect the lead end 101 of the bus bar 100 during transportation, the lead end 101 is usually bent. In order to prevent the lead end 101 from being pressed too tightly during bending, a piece of tape 102 is attached to the bend before bending, as shown in FIG. Figure 3 shown.

[0052] Then, when the photovoltaic panel enters the junction box and the photovoltaic panel automatic assembly machine of the present invention, the lead end 101 of the bus bar 100 needs to be straightened first, then the tape 102 is torn off, and then the lead end 101 of the bus bar 100 is shaped to a suitable angle for easy installation of the junction box.

The total bracket 10 for straightening, tearing and shaping is usually driven by a synchronous wheel and synchronous belt mechanism driven by a servo motor, which is called the first X-axis drive device here. Since the first X-axis drive device is a mature existing technology, its specific structure is not described here.

[0055] The glue straightening and tearing shaping component comprises a glue straightening and tearing shaping sub-bracket 15 .

[0056] In this embodiment, the straightening and glue-tearing shaping sub-bracket 15 is a rectangular frame structure.

[0057] The glue straightening, peeling and shaping sub-brackets 15 can be driven by the first Y-axis driving device to perform reciprocating motion along the glue straightening, peeling and shaping main bracket 10.

[0058] A straightening and peeling glue shaping component 11 is provided on one side of the straightening and peeling glue shaping sub-bracket 15 .

[0059] like Figure 5 and Figure 6 As shown, the straightening and peeling glue shaping component 11 includes a lifting drive component 110 arranged on the straightening and peeling glue shaping sub-bracket 15. The lifting drive component 110 is a commonly used servo motor plus ball screw mechanism. Since the above drive mechanism is a mature existing technology, its specific structure is not repeated here.

[0060] A mounting seat 111 is provided at the movable end of the lifting drive assembly 110 , and a straightening and peeling assembly 112 and a shaping assembly 116 are provided at the bottom of the mounting seat 111 .

[0061] The glue straightening and tearing assembly 112 comprises a glue straightening and tearing lifting cylinder 1121 , on the end plate of which a glue straightening and tearing clamping cylinder 1122 is provided, and on the two clamping blocks of the glue straightening and tearing clamping cylinder 1122 , clamping claw assemblies 113 are provided oppositely.

[0063] A glue suction component 114 with an adsorption function and a straightening retaining frame 115 are provided on the cylinder body of the straightening and peeling glue clamping cylinder 1122.

[0064] The glue suction assembly 114 includes a mounting plate 1140 , on which a lifting cylinder 1141 is disposed, on the piston rod of the lifting cylinder 1141 a suction cup fixing block 1142 is disposed, on the suction cup fixing block 1142 a suction cup 1143 is disposed, and the suction cup 1143 is disposed between two opposite glue clamping claws 1134 .

[0065] In this embodiment, in order to improve the stability of the lifting and lowering of the suction cup 1143, a guide column 1144 is provided on the mounting plate 1140, and a guide sleeve 1145 is provided on the suction cup fixing block 1142, and the guide column 1144 and the guide sleeve 1145 are slidably matched.

[0066] A clamping plane is provided at the end of the clamping claw 1134 , and two opposite clamping claws 1134 are in contact through the clamping plane.

[0067] The straightening retainer 115 includes a retainer support block 1150 arranged on the cylinder body of the straightening and tearing rubber clamping cylinder 1122, and a retaining block 1151 is arranged at the bottom of the retainer support block 1150, and the retaining block 1151 is arranged between two oppositely arranged straightening claws 1133.

[0068] During operation, the straightening and peeling glue clamping cylinder 1122 is started to open the two straightening claws 1133 and the glue clamping claws 1134. Then, the straightening and peeling glue lifting cylinder 1121 drives the straightening claws 1133 and the glue clamping claws 1134 to reach above the lead end 101 of the bus bar 100, and the straightening and peeling glue clamping cylinder 1122 is started again to make the straightening claws 1133 move toward each other and scoop up the lead end 101; then, the straightening and peeling glue clamping cylinder 1122 is started to open the two straightening claws 1133 and the glue clamping claws 1134. The straight claw 1133 and the glue clamping claw 1134 are opened, and the first X-axis drive device and the first Y-axis drive device cooperate to move the suction cup 1143 to the top of the tape 102, and the lifting cylinder 1141 drives the suction cup 1143 to descend. After the suction cup 1143 sucks up the tape 102, the glue clamping claw 1134 clamps the tape 102, and the lifting cylinder 1121 drives the glue clamping claw 1134 to rise, and the tape 102 is torn off the lead end 101 of the bus bar 100.

[0069] like Figure 4 As shown, a glue tray 16 is also provided on the frame, and the adhesive tape 102 torn off by the glue clamping claw 1134 is placed in the glue tray 16 .

[0072] In the above structure, since the straightened lead end 101 may have an inconsistent standing angle problem, for the sake of safety, in order to facilitate the smooth insertion of the lead end 101 into the junction box, the straightened lead end 101 is shaped, and the shaping lifting cylinder 1161 can drive the transverse holding block 1166 and the shaping claw 1164 to achieve lifting. After the shaping clamping cylinder 1162 is opened, the transverse holding block 1166 is moved to the top of the lead end 101, and then the shaping clamping cylinder 1162 is started to make the shaping claw 1164 impact the transverse holding block 1166 from the opposite direction, so that the lead ends 101 on both sides of the transverse holding block 1166 are fitted to the transverse holding block 1166, so that the shape of the lead end 101 is regular, thereby achieving the purpose of shaping.

The main glue bracket 20 is usually driven by a synchronous wheel and synchronous belt mechanism driven by a servo motor, which is called the second X-axis drive device here. Since the second X-axis drive device is a mature existing technology, its specific structure is not described here.

[0088] In this embodiment, the second clamping assembly 324 includes a gear 3240 rotatably provided on the second clamping bracket 323, and a first rack 3241 and a second rack 3242 are slidably provided on the second clamping bracket 323. The first rack 3241 and the second rack 3242 are slidably provided on the second clamping bracket 323 through a slide rail and a slider. The first rack 3241 and the second rack 3242 are arranged relatively parallel to each other, and the first rack 3241 and the second rack 3242 are both engaged with the gear 3240. A rack driving device is provided on the second clamping bracket 323, which can drive the first rack 3241 or the second rack 3242 to translate.

[0089] In this embodiment, the rack drive device is a cylinder 3243 , the cylinder body of the cylinder 3243 is disposed on the second clamping bracket 323 , and the piston rod of the cylinder 3243 is connected to the first rack 3241 or the second rack 3242 .

[0091] In this embodiment, the second clamping blocks 3245 are made of PU, and anti-slip grooves are provided on two opposite surfaces of the two second clamping blocks 3245 .

[0092] In the above structure, the first manipulator 311 can arrange the wired junction boxes in the wired junction box warehouse 312 neatly on the conveyor belt device 313, which is convenient for transportation and positioning in the next step. Then the first manipulator 311 places the wired junction boxes on the conveyor belt device 313 on the wired junction box positioning seat 314, which is convenient for the second manipulator 321 to grab. The wireless junction box supply device 315 can automatically and continuously convey the wireless junction boxes to a position convenient for the second manipulator 321 to grab. The two second manipulators 321 arranged relatively to each other can grab the wired junction boxes and / or wireless junction boxes according to the actual needs of the processed solar panels. In this solution, the two second manipulators 321 can be started at the same time, and multiple wired junction boxes and / or wireless junction boxes can be grabbed at the same time and placed on the photovoltaic panels, so that the processing efficiency is high.

[0093] After the junction box is placed on the photovoltaic panel by the junction box loading device 32, the lead end 101 of the busbar 100 passes through the junction box. The next step is to bend the lead end 101 again so that the lead end 101 contacts the electrode in the junction box. Therefore, a busbar bending device needs to be set up.

[0094] The busbar bending device 4 includes a bending sub-bracket, and the structure and driving mode of the bending sub-bracket are consistent with the structure and driving mode of the gluing main bracket 20.

[0097] The lead end 101 of the busbar 100 cannot be tightly connected to the electrode in the junction box only by the busbar bending device 4, so the lead end 101 needs to be tightly connected to the junction box by a busbar pressing device before welding.

[0098] like Figures 18 to 21 As shown, the busbar pressing and welding device 5 includes a pressing and welding main bracket 50 that reciprocates along the X-axis direction of the frame.

An elastic member is provided between the upper stopper 5213 and the lower mounting block 5214. In this embodiment, the elastic member is a spring 5216. A clamping block 5217 is provided at the bottom of the lower mounting block 5214 so that the lower mounting block 5214 can contact the wiring terminal of the bus bar when it moves downward to a certain position.

[0103] The double-rod cylinder 5210 starts to drive the clamping block 5217 downward, and the bottom surface of the clamping block 5217 contacts the lead end 101 of the busbar 100. Due to the provision of the spring 5216, the lower mounting block 5214 and the clamping block 5217 have a certain elastic stroke, which will not deform the lead end 101 and the electrode in the junction box, and can ensure that sufficient clamping force is applied to the lead end 101, so that the lead end 101 is tightly connected to the electrode in the junction box.

[0104] like Figure 20 to Figure 21 As shown, a welding assembly 53 for welding the lead end 101 of the bus bar and the electrode in the junction box is provided on the other side of the pressing and welding sub-bracket 51 .

An elastic ring is provided on the driving wheel 53121, and the driving wheel 53121 and the driven wheel 53122 can clamp the welding wire. When the welding wire extraction motor 53120 is started, the welding wire extraction assembly 5312 can pull out the welding wire from the welding wire roll on the welding wire reel support 5311.

[0108] The welding wire extraction assembly 5312 also includes a wire outlet nozzle 53123, through which the welding wire can be continuously output.

A welding wire receiving groove 5333 with an inverted trapezoidal cross section is provided at the bottom of the clamping welding portion 5332. Since the tin wire is soft, when the clamping welding portion 5332 is pressed down, the tin wire can be inserted into the welding wire receiving groove 5333. The clamping welding portion 5332 is used as a welding head. When the clamping welding portion 5332 clamps the welding wire and moves it to the junction box to contact the lead terminal 101 and the electrode in the junction box, the clamping welding portion 5332 is energized to melt the tin wire and weld the lead terminal 101 and the electrode together.
