The overturn driving mechanism 1 drives the two clamping ends of the overturn clamping mechanism between the first orientation and the second orientation. position change. Specifically, the two clamping ends of the overturning clamping mechanism are rotated so that each clamping end can perform cyclic position conversion between the first orientation and the second orientation. When one of the clamping ends clamps When actuating, the other clamping end performs the loosening action synchronously.

By flipping the clamping ends of the two different orientations of the clamping mechanism, the cyclic positions between the first orientation and the second orientation are respectively changed, and the product is taken and clamped at the same time, and the loosening and unloading after the flip transfer is carried out, which improves the product. flipping efficiency. The product in this embodiment is a battery cell.

Specifically, the overturning frame 11 includes two gantry support frames 111 , two connecting and fixing plates 112 and two overturning bearing seats 113 . The two gantry support frames 111 are arranged in parallel, and there is an interval between the two gantry support frames 111 . Both ends of each connecting and fixing plate 112 are respectively connected to the corresponding lower ends of the two gantry support frames 111 , so that the two gantry support frames 111 are connected into one body, and the entire turning frame 11 forms a stable frame structure.

The turning shaft 12 can be rotated in a 360-degree cycle through the above two methods, and can be paused after each rotation of 180 degrees.

In this embodiment, it is defined that the first orientation is directly above the flip axis 12, and the second orientation is directly below the flipped 12, and the first orientation and the second orientation are on the same straight line. Preferably, the first orientation and the second orientation are on the same straight line. The central axis of the second orientation overlaps and overlaps with the central axes of the first overturning clamping mechanism 2 and the second overturning clamping mechanism 3 .

After starting, the turning shaft 12 first rotates 180 degrees, driving the first turning and clamping mechanism 2 to move from the first orientation to the second position, so that the first turning and clamping mechanism 2 rotates 180 degrees, and then the first turning and clamping mechanism 2 The clamped cell rotates 180 degrees and then moves to the second orientation to complete the flipping of the cell; at the same time, the rotation of the flip shaft 12 by 180 degrees also drives the second flip clamping mechanism 3 to move from the second orientation to the first orientation , so that the second overturning clamping mechanism 3 rotates 180 degrees, and then the clamping end of the second overturning clamping mechanism 3 rotates 180 degrees and then moves to the first orientation, and faces directly upward. Afterwards, the second turning and clamping mechanism 3 clamps the transferred new battery cell, that is, the picking and clamping process. At the same time, the first turning and clamping mechanism 2 releases the battery cell that has been turned 180 degrees. That is, the loosening and unloading process after turning over and transferring.

In the process of pairing the quadrupole tabs of the battery cells, the transmission mechanism 4 transmits the battery cells, and the battery cells clamped by the first flipping clamping mechanism 2 and the second flipping clamping mechanism 3 are placed on the transmission mechanism 4 to realize electric charging. The turning over of the core, or placing it on the battery core conveyed by the transmission mechanism 4, realizes the turning and stacking of the battery core. Specifically, the transmission mechanism 4 includes a transmission support frame 41 and a transmission line 42 . The transmission line 42 is arranged on the upper end of the transmission support frame 41, and the transmission line 42 is located directly below the beam of the gantry support frame 111. When the turning shaft 12 drives the first turning clamping mechanism 2 or the second turning clamping mechanism 3 to turn over to the second position, The battery cell clamped by the second overturning and clamping mechanism 2 or the second overturning and clamping mechanism 3 is located directly above the transmission line 42 .

Let’s take the example of flipping and stacking electric cells as an example. For the sake of easy understanding, the cell held by the first flipping clamping mechanism 2 or the second flipping clamping mechanism 3 is now defined as the B cell, and the cell transmitted by the transmission line 42 is A Batteries. A plurality of A cells are sequentially arranged on the transmission line 42 at intervals, and the transmission line 42 drives a plurality of A cells to pass directly under the first flipping and clamping mechanism 2 or the second flipping and clamping mechanism 3, and every two adjacent A cells The distance between them is equal to the distance between the B batteries clamped by the two first overturning clamping mechanisms 2 , and is also equal to the distance between the B batteries clamped by the two second overturning clamping mechanisms 3 . Initially, the two first flipping and clamping mechanisms 2 are located in the second orientation, and the transmission line 42 transmits two adjacent A cells to the right below the two first flipping and clamping mechanisms 2 and then pauses, and then the two first flipping clamps The holding mechanism 2 releases the clamped B batteries, so that the two B batteries are stacked on the two A batteries. Then, the turning shaft 12 drives the first turning and clamping mechanism 2 to move from the second position to the first position, and at the same time drives the second turning and clamping mechanism 3 to move from the first position to the second position. At the same time, the transmission line 42 transmits the subsequent The two adjacent A batteries are directly below the two second flip clamping mechanisms 3 . Then, the two second overturning clamping mechanisms 3 loosen the clamped B batteries and stack them on the two A batteries. At the same time, the first overturning clamping mechanism 2 in the first position clamps the new batteries B cell. Through the above actuation process, the transmission of A cell and the flipping of B cell are carried out at the same time, and the loading of B cell and the stacking of BA cell are carried out at the same time, which reduces the loading, flipping and The stacking time improves the efficiency of pairing.

Preferably, the turning device in this embodiment further includes a transfer mechanism (not shown in the figure). The transfer mechanism is set at the first position; the transfer mechanism transfers the products, and the first turning and clamping mechanism 2 and the second turning and clamping mechanism 3 clamp the products transferred by the transferring mechanism. The transfer mechanism in this embodiment can be a combination of a linear module and a manipulator. The number of manipulators is two. The two manipulators can hold two B batteries at one time, and move to the second B cell under the action of the linear module. One orientation, and correspondingly placed on the supporting block 212 of the first turning and clamping mechanism 2 or the second turning and clamping mechanism 3, to realize the automatic feeding of the B battery.

Referring again to FIG. 1 and FIG. 2 , the overturning device in this embodiment further includes a feeding detection member 5 . The feeding detection part 5 is used to detect whether the manipulator of the transfer mechanism is transferring. Specifically, the feeding detection part 5 is arranged on the flip bearing seat 113, and its detection end faces upwards to detect whether the manipulator of the moving mechanism has moved past. The feeding detection part 5 in this embodiment can adopt a photoelectric sensor.

To sum up, through the cyclic position change between the first orientation and the second orientation of the first turning and clamping mechanism and the second turning and clamping mechanism respectively, the material picking and clamping of the product and the loosening and unloading after the turning and transferring are carried out at the same time, The flipping efficiency of the cell is improved. In addition, through the cooperation with the transmission mechanism and the transfer mechanism, the automatic charging of the battery cells, the automatic transfer of the stacked batteries, and the automation of the stacking are realized, thereby improving the pairing efficiency of the quadrupole tabs of the battery cells.
