[0018] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0019] As Figures 1-5 shown, the linear double-station alternating synchronous conveying and fine positioning mechanism provided by the present invention includes a lower frame 1. On one side wall at the top of the lower frame 1, there is a PCM sheet bin 2. On the wall at the top of the lower frame 1 at a position on one side of the PCM sheet bin 2, there is also a transfer four-axis robot 3. On the rear end wall at the top of the lower frame 1, there is also a handling manipulator 12. On one side wall of the handling manipulator 12, there is a PCM sheet bin CCD 4. On the wall at the center position of the front end at the top of the lower frame 1, there is also a PCM sheet flipping and positioning mechanism 5. At a position on one side of the PCM sheet flipping and positioning mechanism 5 on the top of the lower frame 1, there is also a linear double-station alternating synchronous conveying and fine positioning mechanism 6. The linear double-station alternating synchronous conveying and fine positioning mechanism 6 includes a first linear module 13, a second linear module 14 and a third linear module 15. On the wall at the front end at the top of the lower frame 1 at a position on one side of the PCM sheet flipping and positioning mechanism 5, there is also a PCM sheet loading four-axis robot 7. At a position on the wall at the top of the lower frame 1 below the transfer four-axis robot 3, there is also a tab pressing jaw mechanism 8. On the other side wall at the top of the lower frame 1, there is also a servo fork 24. On the top wall of the servo fork 24, there are a number of vacuum jigs 25. On the walls at the top of the lower frame 1 at positions on one side of the servo fork 24, there are respectively a laser welder 9 and a pad shaping mechanism 10. On the wall at the top of the lower frame 1 at a position on one side of the pad shaping mechanism 10, there is also a pad detection mechanism 11.

[0020] The bottom walls of the first linear module 13 and the second linear module 14 are respectively fixedly installed on the top wall of the lower frame 1. The second linear module 14 is fixedly installed on one side wall of the first linear module 13, and the first linear module 13, the second linear module 14 and the third linear module 15 are respectively electrically connected to an external controller.

[0021] A second positioning seat 21 is movably installed on one side wall at the front end of the first linear module 13, and a first positioning seat 20 is also movably installed on one side wall at the front end of the second linear module 14.

[0022] A second clamping cylinder 19 is fixedly installed on the top wall of the second positioning seat 21, and a second lifting cylinder 17 is also fixedly installed on the lower wall at the front end of the second positioning seat 21. A first clamping cylinder 18 is fixedly installed on the top wall of the first positioning seat 20, and a first lifting cylinder 16 is also fixedly installed on the front wall of the first positioning seat 20.

[0023] The PCM board loading four-axis robot 7 includes a four-axis robot body 22, and a PCM board gripper 23 is fixedly installed on the bottom wall of the four-axis robot body 22.

[0024] It should be noted that the present invention is a linear double-station alternating synchronous conveying and precise positioning mechanism. When in use, it is fed through the PCM board magazine 2. Subsequently, the transfer four-axis robot 3 takes out the PCM board from the PCM board magazine 2 and places it into the PCM board flipping and positioning mechanism 5. Then, the four-axis robot body 22 in the PCM board loading four-axis robot 7 drives the PCM board gripper 23 to grab the PCM board in the PCM board flipping and positioning mechanism 5, and finally places the PCM board into the linear double-station alternating synchronous conveying and precise positioning mechanism 6. When the PCM board enters the first positioning seat 20 in the linear double-station alternating synchronous conveying and precise positioning mechanism 6, the second positioning seat 21 is at the welding station. At the same time, the second lifting cylinder 17 is in the extended state, the second clamping cylinder 19 is in the clamping state, and the third linear module 15 is in the forward state. At this time, the first lifting cylinder 16 is in the extended state, and the battery cell tab in the vacuum jig 25 has been placed on the welding copper column on the first positioning seat 20. If the PCM board is placed into the first positioning seat 20 at this time, the nickel sheet of the PCM board is placed above the battery cell tab, and the first clamping cylinder 18 clamps the PCM board. At this time, the second linear module 14 drives the first positioning seat 20 on the first positioning seat 20 to move. Subsequently, the servo fork 24 drives the vacuum jig 25 to move, and the relative positions of the battery cell and the PCM board will not change during their synchronous movement. When the welding of the second positioning seat 21 is completed, the second clamping cylinder 19 opens, and at this time, the second lifting cylinder 17 retracts. Finally, the third linear module 15 retreats to make way. Then, when the first positioning seat 20 enters the welding working position, at this time, when the first linear module 13 moves, the second positioning seat 21 moves away from the first positioning seat 20. After reaching the position, the third linear module 15 advances to make the second positioning seat 21 enter the PCM board loading position.

[0025] When the PCM board is placed into the second positioning seat 21, the first rising cylinder 16 at the welding station for the first positioning seat 20 is in the extended state, and the first clamping cylinder 18 is in the clamping state. At this time, the second rising cylinder 17 is in the extended state, and the battery cell tab in the vacuum jig 25 has been placed on the welding copper column on the second positioning seat 21. If the PCM board is placed on the second positioning seat 21 at this time, the nickel sheet of the PCM board is placed above the battery cell tab, and the second clamping cylinder 19 clamps the PCM board. At this time, the first linear module 13 drives the second positioning seat 21 to move. At the same time, the servo fork 24 drives the vacuum jig 25 to move, and the relative positions of the battery cell and the PCM board will not change because their movements are synchronized. In addition, after the welding of the first positioning seat 20 is completed, the first clamping cylinder 18 opens, and the first rising cylinder 16 retracts to make way. Subsequently, the second positioning seat 21 enters the welding working position. At this time, the second linear module 14 moves to make the first positioning seat 20 move away from the second positioning seat 21 and directly enter the position for placing the PCM board. The first positioning seat 20 moves up and down through the first rising cylinder 16, and the second positioning seat 21 moves back and forth through the second linear module 14. When the first positioning seat 20 is in the welding position, the second positioning seat 21 is in the loading position; when the first positioning seat 20 is in the loading position, the second positioning seat 21 is in the welding position. The first positioning seat 20 and the second positioning seat 21 work alternately.
