The tape pulling mechanism 3200 is provided on the frame 9000 so as to be movable back and forth in the X ' direction, and accordingly, the tape pulling mechanism 3200 includes a first tape pulling mechanism for pulling out s first solder tape strips extending in the X ' direction simultaneously from s sets of the first solder tape winding mechanisms 3102, and a second tape pulling mechanism for pulling out n second solder tape strips 2 extending in the X ' direction simultaneously from n sets of the second solder tape winding mechanisms 3101. Wherein, the X 'direction intersects with the Y direction, and in this embodiment, the X' direction is parallel to the X direction.
The cutting mechanism 3300 is configured to cut the solder ribbon strip, so that the solder ribbon strip pulled out by the tape pulling mechanism 3200 is separated from the solder ribbon strip wound on the solder ribbon winding mechanism 3100, and the cut solder ribbon strip is the second raw solder ribbon 21 and the first raw solder ribbon 31 extending along the X' direction. The cutting mechanism 3300 continues to cut the second raw solder strip 21, resulting in a plurality of solder strips 211 extending in the X' direction. Specifically, the cutting mechanism 3300 has (m + 1) sets arranged at intervals along the X 'direction, the two sets of cutting mechanisms 3300 located at two ends of the X' direction can simultaneously cut the n second solder ribbon strips 2 that are pulled out, so as to obtain n second original solder ribbons 21 extending along the X 'direction, the cutting mechanism 3300 located in the middle can further divide each second original solder ribbon 21 into m solder ribbons 211, and each solder ribbon 211 extends along the X' direction. For the first solder ribbon strip, the cutting mechanism 3300 is also used to cut the first solder ribbon strip into s first raw solder ribbons 31 extending along the X' direction in this embodiment, and both ends of the first raw solder ribbons 31 can be clamped by the clamping assembly 3600. Such cutting means include, but are not limited to, mechanical cutting, laser cutting, and the like.
It should be noted that in other embodiments, for example, in a scenario limited by factory space, the X' direction may not be parallel to the X direction. In this case, the solder ribbon preparing apparatus 3000 is further provided with a rotating mechanism for integrally rotating the second raw solder ribbon 21 and the first raw solder ribbon 31 extending in the X' direction to extend in the X direction, so that the subsequent steps can be performed.

Specifically, m groups of fixture 3400 arranges the setting along the X direction, every group of fixture 3400 all includes n clamping unit 4, every clamping unit 4 is including dividing two sets of clamping jaws 41 of locating both sides again, fixture 3400 still includes the centre gripping cylinder 5 that is used for driving adjacent two sets of clamping jaws 41 to move in opposite directions or reverse direction, thereby every clamping unit 4 can grasp the both ends of a welding strip 211, every group of fixture 3400 can grasp all welding strips 211 that are parallel to each other in a set of welding strip group 20 simultaneously, thereby make all welding strips 211's position relatively fixed, can not deviate from its position that should, and can make welding strip 211 keep the state of tightening. Therefore, the rotating mechanism 3500 can drive the clamping mechanism 3400 to rotate integrally around the rotation center line P, the rotation center line P extends along the Z direction, and after the rotating mechanism 3500 rotates by 90 degrees, the rotating mechanism 3500 enables the extending directions of all the welding strips 211 clamped by the clamping mechanism 3400 to rotate to the Y direction at the same time. In this embodiment, the Z direction is an upward extending direction, and the m sets of rotation mechanisms 3500 are independent from each other and can rotate separately or simultaneously.
In other embodiments, the cutting mechanism 3300 may be integrated with the clamping mechanism 3400 to facilitate cutting the raw solder strip 21.
From above, after the first raw solder ribbon 31 extending in the X direction and the solder ribbon group 20 extending in the Y direction are prepared, they need to be transferred to the first arranging station 4100 by the third transfer device. In order to realize accurate positioning, the third transmission device specifically comprises an X-direction moving shaft 8101, a Y-direction moving shaft 8102 and a Z-direction moving shaft 8103, wherein the X-direction moving shaft 8101 extends along the X direction, the Y-direction moving shaft 8102 extends along the Y direction, and the Z-direction moving shaft 8103 extends along the Z direction.
