Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and particularly to a pressure welding mechanism. Background Art

[0002] During the production of photovoltaic modules, it is necessary to weld the bus bar and the battery string relatively so that multiple battery strings can form a complete series circuit. In the prior art, usually, the bus bar and the battery string are both laid on the insulating glass first, and then the insulating glass with the bus bar and the battery string laid thereon is transferred to a welding mechanism for welding. However, the above solution has the following defects: First, the welding efficiency is relatively low; Second, the bus bar and the battery string may be relatively displaced during the transfer process, which greatly affects the welding accuracy of the bus bar and reduces the quality of the obtained photovoltaic module.

The first welding component can be buckled on the carrying component during its movement stroke.

[0006] By adopting the above technical solution, the first welding component can weld the end of the battery string and the bus bar on the carrying component during its movement stroke, without the need to transfer the bus bar and the battery string anymore, greatly improving the welding accuracy and welding efficiency.

Detailed implementation manners

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Referring to Figure 1-2 As shown, a pressure welding mechanism is shown, including a bracket 4, a sliding plate 5 disposed on the bracket 4 and translatable along the length direction of the bracket 4, a second driving assembly 6 for driving the sliding plate 5 to translate, a bearing assembly 1 disposed on the sliding plate 5, two first welding assemblies 2 that are liftable and translatable along a direction approaching or departing from the bearing assembly 1, and two first driving assemblies 3 respectively for driving the two first welding assemblies 2 to move. Among them, the length direction of the bearing assembly 1 is the same as the width direction of the bracket 4, the two first welding assemblies 2 are respectively located on both sides of the width direction of the bearing assembly 1, the translation direction of the two first welding assemblies 2 is the same as the width direction of the bearing assembly 1, and the first welding assembly 2 can be buckled on the bearing assembly 1 during its movement stroke.

[0028] When welding the bus bar and the battery string, the bus bar is placed on the bearing assembly 1. The bus bar carried on the bearing assembly 1 moves to one end of the bracket 4 driven by the sliding plate 5. Subsequently, one end of the battery string is lowered onto the bearing assembly 1. One of the two first welding assemblies 2 that is far from the battery string is buckled on the battery string after a translation stroke and a lifting stroke. Among them, the first welding assembly 2 is a welding machine, and its bottom has a welding head, and the welding head can weld one end of the battery string and the bus bar; after welding is completed, the battery string is driven to rise. Subsequently, another bus bar is placed on the bearing assembly 1. The bus bar carried on the bearing assembly 1 moves to the other end of the bracket 4 driven by the sliding plate 5. Subsequently, the above operations are repeated to weld the other end of the battery string and the bus bar.

[0029] In this way, the first welding assembly 2 can weld the end of the battery string to the bus bar on the bearing assembly 1 during its movement stroke, without the need to transfer the bus bar and the battery string any more, greatly improving the welding accuracy and efficiency.

[0030] In this embodiment, in combination with Figure 2 As shown, the first driving assembly 3 includes a first cylinder 31 and a second cylinder 32. The piston rod of the first cylinder 31 extends and retracts along the translation direction of the first welding assembly 2, and its end is connected to a translation frame 33. The second cylinder 32 is arranged on the translation frame 33. The piston rod of the second cylinder 32 extends and retracts along the vertical direction, and its end is connected to the first welding assembly 2. Among them, the translation frame 33 extends along the length direction of the bearing assembly 1. There are six second cylinders 32, and three second cylinders 32 are respectively arranged on each translation frame 33 along its length direction.

[0031] In this embodiment, the bearing assembly 1 includes a bearing frame 11 and a bearing platform 12 arranged on the bearing frame 11. A heating module 14 is built in the bearing platform 12. The heating module 14 can be heating devices such as heating rods and heating wires, which can heat the bus bar on the bearing platform 12 to facilitate the welding of the bus bar and the battery string.

[0032] A number of adsorption holes 13 are spaced apart along the length direction at the top of the bearing platform 12. The adsorption holes 13 are communicated with an external fan. Through the suction of the fan, a negative pressure is formed in the adsorption holes 13 to suck the bus bar, avoiding the offset of the bus bar during the welding process and improving the welding accuracy.

[0033] In this embodiment, the bracket 4 includes two parallel struts 41, and both ends of the sliding plate 5 are slidably arranged on the two struts 41 respectively. The second driving assembly 6 is a matching structure of a motor and a synchronous pulley. Synchronous pulleys are respectively arranged on the two struts 41, and the motor drives the two synchronous pulleys to run synchronously through a long rod. Both ends of the sliding plate 5 are respectively connected to the belts of the two synchronous pulleys.

[0034] In this embodiment, the pressure welding mechanism further includes a second welding assembly 7 suspended above the middle of the bracket 4 and capable of lifting, and a third driving assembly 8 for driving the second welding assembly 7 to lift. The second welding assembly 7 is also a welding machine, and its bottom has a welding head. The third driving assembly 8 includes two cylinders. Since the first welding assembly 2 is located below the battery string and cannot weld the middle of the battery string, while the second welding assembly 7 is located above the battery string and can cooperate with the bearing assembly 1 to weld the bus bar in the middle of the battery string. The first welding assembly 2 and the second welding assembly 7 cooperate with each other to further improve the welding accuracy and efficiency.

[0035] The implementation principle of a pressure welding mechanism according to an embodiment of the present application is as follows:

[0036] Place the bus bar on the carrier assembly 1. The bus bar carried on the carrier assembly 1 is moved to one end of the bracket 4 driven by the sliding plate 5. Subsequently, lower one end of the battery string onto the carrier assembly 1. Then, one of the two first welding assemblies 2 that is far from the battery string is pressed onto the battery string after a translation stroke and a lifting stroke, and the first welding assembly 2 welds one end of the battery string to the bus bar;

[0037] Subsequently, drive the battery string to rise. Then, place another bus bar on the carrier assembly 1. The bus bar carried on the carrier assembly 1 is moved to the middle of the bracket 4 driven by the sliding plate 5. Subsequently, lower the middle of the battery string onto the carrier assembly 1. The second welding assembly 7 descends and welds the middle of the battery string to the bus bar;

[0038] Subsequently, drive the battery string to rise again. Then, place another bus bar on the carrier assembly 1. The bus bar carried on the carrier assembly 1 is moved to the other end of the bracket 4 driven by the sliding plate 5. Subsequently, lower the other end of the battery string onto the carrier assembly 1. Then, one of the two first welding assemblies 2 that is far from the battery string is pressed onto the battery string after a translation stroke and a lifting stroke, and the first welding assembly 2 welds the other end of the battery string to the bus bar.

[0039] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly.
