[0087] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0088] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0089] Refer toFigures 1 to 3 , an embodiment of the present utility model provides a welding conveyor line, including: a conveying assembly 10, a conveyor belt 20 and a bottom plate assembly 30. The conveyor belt 20 is arranged on the conveying assembly 10 and is used to drive the object to be welded to move under the drive of the conveying assembly 10. Among them, the object to be welded can be a solar cell. When welding a solar cell, the solar cell is placed on the conveyor belt 20, and the conveyor belt 20 moves under the drive of the conveying assembly 10, thereby driving the solar cell on the conveyor belt 20 to move.

[0090] The bottom plate assembly 30 includes a heating bottom plate 301, a constant temperature bottom plate 302 and a cooling bottom plate 303. The heating bottom plate 301, the constant temperature bottom plate 302 and the cooling bottom plate 303 are sequentially arranged on the conveying assembly 10. The heating bottom plate 301 is used to heat up the object to be welded before welding, the constant temperature bottom plate 302 is used to keep the temperature of the object to be welded during welding, and the cooling bottom plate 303 is used to cool down the object to be welded after welding.

[0091] As Figure 2 and Figure 3As shown in the figure, the bottom plate assembly 30 is composed of multiple independent bottom plates. Heating devices 30212, heat dissipation devices and / or temperature control devices are respectively provided on the heating bottom plate 301, the constant temperature bottom plate 302 and the cooling bottom plate 303 to control the temperatures of the heating bottom plate 301, the constant temperature bottom plate 302 and the cooling bottom plate 303. Among them, one or more independent bottom plates can be respectively provided on the heating bottom plate 301, the constant temperature bottom plate 302 and the cooling bottom plate 303. Each independent bottom plate is provided with a heating, heat dissipation and temperature control system and is sequentially arranged on the conveying assembly 10; the front section is a stepped heating bottom plate 301, the middle section is a constant temperature welding bottom plate 3021, and the rear section is a stepped cooling bottom plate 303. The solar cell moves driven by the conveyor belt 20 and first passes through the heating bottom plate 301. The heating bottom plate 301 can be provided with two independent bottom plates, namely a first heating bottom plate 3011 and a second heating bottom plate 3012, and the solar cell can be preheated through the heating bottom plate 301. After the solar cell is preheated by the first heating bottom plate 3011 and the second heating bottom plate 3012, it reaches the constant temperature bottom plate 302; among them, the constant temperature bottom plate 302 can include two independent bottom plates, namely a welding bottom plate 3021 and a welding curing bottom plate 3022. Since the temperature of the solar cell rises to a certain temperature value after being preheated by the heating bottom plate 301, the solar cell can be welded by a welding light box at the welding bottom plate 3021, thereby reducing the heating time of the solar cell, realizing flexible welding of the solar cell, and avoiding hidden cracks in the cell caused by excessive instantaneous temperature difference. After the welding of the solar cell is completed, the conveyor belt 20 continues to drive the solar cell to move to the welding curing bottom plate 3022, so that the welded part of the welded solar cell can be cured. Subsequently, the conveyor belt 20 continues to drive the solar cell to move to the cooling bottom plate 303. Among them, the cooling bottom plate 303 can be provided with three independent bottom plates, namely a first cooling bottom plate 3031, a second cooling bottom plate 3032 and a third cooling bottom plate 3033, and the solar cell is cooled through the cooling bottom plate 303. This can avoid problems such as solder strip peeling or false soldering caused by cell deformation when the welding is not fully cured.

[0092] Among them, in another embodiment of the present invention, the bottom plate assembly 30 may further include an adsorption bottom plate 304. The adsorption bottom plate 304 is located at the end of the heating bottom plate 301 away from the welding bottom plate 3021. The adsorption bottom plate 304 is used to place the solar cell and adsorb the solar cell. In this way, the conveyor belt 20 can drive the solar cell to move to the heating bottom plate 301.

[0093] Refer to Figure 4, the constant temperature bottom plate 302 includes a welding bottom plate 3021, and the welding bottom plate 3021 includes: a welding support plate 30211, a heating device 30212, and a temperature sensor 30213. The heating device 30212 is disposed within the welding support plate 30211 to heat the welding support plate 30211; the temperature sensor 30213 is used to detect the temperature of the welding support plate 30211, and when the temperature of the welding support plate 30211 reaches a set value, the heating device 30212 stops heating. As Figure 4 shown in, the heating device 30212 may be a heating rod 30212, and the heating rod 30212 is disposed within the welding support plate 30211. Thus, the heating rod 30212 can heat up the welding support plate 30211. The temperature sensor 30213 may be a thermocouple 30213, and the thermocouple 30213 is disposed within the welding support plate 30211. Thus, the thermocouple 30213 can monitor the temperature of the welding support plate 30211. When the welding support plate 30211 reaches the set temperature, the heating rod 30212 stops heating, and when it is lower than the set temperature, the heating is restarted to ensure that the welding support plate 30211 is in a constant temperature state.

[0094] Refer to Figure 4 , the welding bottom plate 3021 further includes: a first compressed air joint 30214, the first compressed air joint 30214 is installed on the welding support plate 30211, and the welding support plate 30211 is further provided with a bottom plate heat dissipation air outlet 302111. The first compressed air joint 30214 is in communication with the bottom plate heat dissipation air outlet 302111. The first compressed air joint 30214 is used to connect a compressed air output device to introduce compressed air into the welding support plate 30211 and output the compressed air from the heat dissipation air outlet to dissipate heat from the welding support plate 30211. As Figure 4 shown in, compressed air can be introduced into the welding support plate 30211 through the first compressed air joint 30214 and output from the heat dissipation air outlet. In this way, the compressed air penetrates the entire welding support plate 30211 for heat dissipation, ensuring the stability and controllability of the temperature and avoiding the occurrence of uncontrollable heat accumulation and overheating.

[0095] Refer to Figure 4The welding base plate 3021 also includes: a heat dissipation diaphragm 30215, a heat dissipation rod 30216, and a second compressed air connector 302162. The heat dissipation diaphragm 30215 is installed at the bottom of the welding support plate 30211 to dissipate heat for the welding support plate 30211; the heat dissipation rod 30216 is provided with a diaphragm heat dissipation outlet hole 302161; the second compressed air connector 302162 is installed on the heat dissipation rod 30216, and the second compressed air connector 302162 is interconnected with the diaphragm heat dissipation outlet hole 302161. The second compressed air connector 302162 is used to connect a compressed air output device to introduce compressed air into the heat dissipation rod 30216, and output compressed air from the diaphragm heat dissipation outlet hole 302161 to the heat dissipation diaphragm 30215 to dissipate heat for the heat dissipation diaphragm 30215. Figure 4 As shown in , by providing a heat dissipation diaphragm 30215 at the bottom of the welding support plate 30211, the welding support plate 30211 can be quickly cooled. In addition, the compressed air can be introduced into the heat dissipation rod 30216 through the second compressed air joint 302162. The heat dissipation rod 30216 is provided with a plurality of diaphragm heat dissipation air outlets 302161, and the plurality of diaphragm heat dissipation air outlets 302161 are respectively aligned with the heat dissipation diaphragm 30215, so that the compressed air can be output to the heat dissipation diaphragm 30215. When heat dissipation is required, the heat dissipation diaphragm 30215 is quickly cooled. Since the heat dissipation diaphragm 30215 is connected to the bottom of the welding support plate 30211, the welding support plate 30211 can be quickly cooled at the same time. In this way, with the support of multiple heat dissipations, the temperature of the welding support plate 30211 is guaranteed to be stable, and heat accumulation and overheating that cannot be controlled are avoided.

[0096] See also Figure 2 and Figure 4 The welding support plate 30211 is also provided with an adsorption hole 302112, and the heat dissipation diaphragm 30215 is also provided with a bottom plate exhaust duct 302151. The adsorption hole 302112 and the bottom plate exhaust duct 302151 are interconnected, and the bottom plate exhaust duct 302151 is used to connect with the exhaust adsorption system to generate adsorption force, so as to adsorb the object to be welded on the welding support plate 30211 through the adsorption hole 302112.

[0097] like Figure 2As shown in , the welding support plate 30211 is provided with uniformly distributed adsorption holes 302112, and the exhaust adsorption system can generate negative pressure adsorption force, so that the solar cell on the welding support plate 30211 can be adsorbed. When the welding strip, solar cell and welding tooling are assembled, the solar cell is adsorbed on the conveyor belt, and the welding strip under the solar cell is pressed and positioned. At the same time, each independent bottom plate of the entire bottom plate assembly 30 is respectively under the action of the adsorption force, so that the battery string is stable and controllable during the conveying process, avoiding deviation and slipping, thereby improving the positioning accuracy of the welding strip and the battery cell, and ensuring the welding quality.

[0098] It should be noted that, although in the embodiment of the utility model, the heating, heat dissipation and temperature control system on the independent bottom plate is introduced only by welding the bottom plate 3021, the above heating, heat dissipation and temperature control system can be protected in each independent bottom of the heating bottom plate 301, the constant temperature bottom plate 302 and the cooling bottom plate 303, so as to realize the temperature control of each heating bottom plate 301, the constant temperature bottom plate 302 and the cooling bottom plate 303.

[0099] See also Figure 5 The bottom plate assembly 30 includes: an exhaust baffle 305, which is installed on one side of the conveying assembly 10. An exhaust joint 3051 is provided on the exhaust baffle 305. The exhaust joint 3051 is used to connect with the exhaust device. The exhaust joint 3051 is connected to the surrounding space of the heat dissipation diaphragm 30215 to extract the hot air generated by the heat dissipation diaphragm 30215 to the outside.

[0100] like Figure 5 As shown in the figure, an exhaust device can be connected through the exhaust connector 3051, wherein the exhaust connector 3051 is provided with an exhaust pipeline and an exhaust collection pipeline 3052, and is provided with an air inlet and an encrypted air inlet, so as to evenly discharge the hot air generated by the heat dissipation diaphragm 30215 into the factory exhaust, thereby avoiding the heat accumulation of hot air in the equipment and drastically changing the ambient temperature to cause over-welding of the battery cells.

[0101] See also Figure 1 , Figure 3 and Figure 6The conveying assembly 10 includes: a conveying frame 101 and a driving assembly 102. The driving assembly 102 includes a driving roller 1021, a No. 1 slave roller 1022, a No. 2 slave roller 1023, a No. 3 slave roller 1024 and a deflection correction slave roller 1025. The driving roller 1021 is installed at one end of the conveying frame 101, and the No. 1 slave roller 1022, the No. 2 slave roller 1023, the No. 3 slave roller 1024 and the deflection correction slave roller 1025 are installed at the other end of the conveying frame 101 respectively. The transmission belt 20 is arranged on the driving assembly 102 to move under the drive of the driving roller 1021. Figure 1 and Figure 6 As shown in , since one end of the transmission belt 20 contacts the driving roller 1021, the other end contacts the No. 1 slave roller 1022, the No. 2 slave roller 1023, the No. 3 slave roller 1024 and the deviation correction slave roller 1025. In this way, the transmission belt 20 can be driven to move by the driving roller 1021, and the No. 1 slave roller 1022, the No. 2 slave roller 1023, the No. 3 slave roller 1024 and the deviation correction slave roller 1025 can be driven to rotate by the transmission belt 20. The No. 1 slave roller 1022, the No. 2 slave roller 1023, the No. 3 slave roller 1024 and the deviation correction slave roller 1025 can ensure that the transmission belt 20 is in a tensioned and stretched state. Among them, the driving roller 1021 is provided with knurling to increase friction and prevent the belt from slipping.

[0102] See also Figure 6 , Figure 7 and Figure 8 The conveying assembly 10 also includes a slave roller deviation correction assembly 1026, which includes: a deviation correction spring 10262 and a deviation correction adjustment rod 10261. One end of the roller shaft of the deviation correction slave roller 1025 is rotatably connected to the conveying frame 101 through a deviation correction shaft 10263. The deviation correction spring 10262 is arranged at a position on one side of the other end of the roller shaft to provide an elastic force to the roller shaft; the deviation correction adjustment rod 10261 is arranged at a position on the other side of the other end of the roller shaft to cooperate with the deviation correction spring 10262 to correct the roller shaft and the deviation correction slave roller arranged outside the roller shaft. Figure 8As shown in , the two ends of the roller shaft can be installed through the first mounting block 10264 and the second mounting block 10265 respectively. One end of the roller shaft is provided with a through hole, and the deflection correction shaft 10263 is installed in the through hole. The deflection correction shaft 10263 is connected to the first mounting block 10264, so that one end of the roller shaft can rotate with the deflection correction shaft 10263 as the axis. The other end of the roller shaft is installed in the second mounting block 10265 through the deflection correction spring 10262. The deflection correction spring 10262 can provide a force for the other end of the roller shaft. In addition, the deflection correction adjustment rod 10261 can also provide a reverse force for the other end of the roller shaft. In this way, by adjusting the correction adjustment rod 10261, the correction spring 10262 can be compressed, so that the roller shaft 10251 can drive the correction slave roller 1025 to rotate, thereby realizing the correction adjustment of the angle of the slave roller 1025, and then adjusting the conveyor belt 20 to be in a positive straightening state to avoid deviation.

[0103] See also Figure 7 The conveying assembly 10 further includes: a tensioning cylinder 1028 and a guide rail assembly 1027. The tensioning cylinder 1028 is installed on the conveying frame 101. The guide rail assembly 1027 is connected to the telescopic rod of the tensioning cylinder 1028. The guide rail assembly 1027 is also connected to the deviation correction slave roller 1025 to drive the deviation correction slave roller 1025 to move, thereby adaptively tensioning the conveyor belt. Figure 7 As shown in , the guide rail assembly 1027 may include a slide rail and a slider, and the tensioning cylinder 1028 may drive the slider to move along the slide rail. The deflection correction slave roller 1025 is fixedly connected to the slider through the first mounting block 10264 and the second mounting block 10265. In this way, the deflection correction slave roller 1025 can be driven to move by the slider, so as to perform adaptive tension control on the conveyor belt.
