[0045] See also Figure 5Specifically, the first conveying mechanism 10 includes a horizontally arranged bracket 101, a rotating shaft 102 installed at one end of the bracket 101, and a conveyor belt 103 wound around the rotating shaft 102. The bracket 101 includes a first support plate 1011 and a second support plate 1012 extending in the horizontal direction. The two ends of the rotating shaft 102 are respectively passed through the first support plate 1011 and the second support plate 1012.

[0047] See also Figure 6 Specifically, the battery injection molding feeder 100 further includes a first camera device 113. The first camera device 113 and the back-side code scanning device 112 are arranged adjacent to each other below the first manipulator 14. The first camera device 113 is used to capture the battery cell image on the first manipulator 14 to locate the battery cell 400 on the first manipulator 14, so as to accurately place the battery cell 400 on the workstation 133 of the turntable 13.

[0048] See also Figure 7Specifically, the first bending device 15 includes a positioning mechanism, a limiting mechanism, a first rotating mechanism and a side pressing mechanism, wherein the positioning mechanism is used to position the battery cell 400; the limiting mechanism includes a third driver 151 and a limiting block 152 connected to the output end of the third driver 151, the limiting block 152 is arranged above the turntable 13 and has a vertical limiting surface 1521 for blocking the FPC 410 of the battery cell 400, and the third driver 151 is used to drive the limiting block 152 to descend along the F1 direction to abut against the upper surface of the FPC 410; the first rotating mechanism includes a fourth driver 153 and a third driver 153 connected to the output end of the fourth driver 153. A bending block 154, the first bending block 154 has a force-applying surface for abutting against the lower surface of the FPC 410, the fourth driver 153 is used to drive the first bending block 154 to rotate so as to bend the FPC 410 upward at a preset angle and make the FPC 410 blocked by the vertical limit surface 1521; the side pressure mechanism includes a fifth driver 155 and a side pressure block 156 connected to the output end of the fifth driver 155, the fifth driver 155 is used to drive the side pressure block 156 to move along the F2 direction to abut against the bending portion 411 of the FPC 410, at this time, the side pressure block 156 and the limit block 152 are respectively against the opposite sides of the bending portion 411 (such as Fig. 9 As shown in FIG. 1 ), the bent portion 411 is pressed straight (since the FPC 410 is flexible, when the first bending block 154 bends the FPC 410, the bend of the FPC 410 will be curved with a certain arc and have a tendency to rebound), and finally the FPC 410 is bent at a preset angle. With the cooperation of the limit block 152, the first bending block 154 and the side pressure block 156, the FPC bending angle is accurate and reliable, and the overall structure of the first bending device 15 is simple, and automated bending can also save time and effort.

[0049] See also Figure 8 , Fig.12 and Fig.13 In one embodiment, the preset angle is 90 degrees, and the plane where the turntable 13 is located is a horizontal plane. When the battery cell 400 is placed on the turntable 13, the FPC 410 on the battery cell 400 is parallel to the horizontal plane, the vertical limit surface 1521 is perpendicular to the plane where the turntable 13 is located, and the force-applying surface of the first bending block 154 is parallel to the plane where the turntable 13 is located when it is in the initial position. After the first bending block 154 rotates 90 degrees, its force-applying surface is perpendicular to the plane where the turntable 13 is located, and the side surface 1561 of the side pressure block 156 facing the vertical limit surface 1521 is also parallel to the vertical limit surface 1521 (the side surface 1561 of the side pressure block 156 facing the vertical limit surface 1521 is perpendicular to the plane where the turntable 13 is located). Of course, in other embodiments, the inclination angles of the vertical limit surface 1521 and the side pressure block 156 relative to the horizontal plane can also be adjusted according to the specific angle of bending the FPC 410 as needed, so it should not be limited to this.

[0050] See also Fig.10 Specifically, the first bending block 154 includes a connecting portion 1541 connected to the output end of the fourth driver 153 and a bending portion 1542 extending from the connecting portion 1541 toward the direction of the turntable 13. A groove 1543 that can accommodate a partial structure of the FPC410 is formed at the upper end of the bending portion 1542. The bending portion 1542 penetrates a side wall of the groove 1543 adjacent to the turntable 13, and the groove 1543 forms a force application surface. During the process of the first bending block 154 rotating from the initial position to 90 degrees, the three side walls 1544 of the groove 1543 can always be arranged around the FPC410.

[0051] More specifically, a slot 1545 is provided on one side where the connecting portion 1541 is connected to the bending portion 1542, and the bending portion 1542 is clamped in the slot 1545. The installation and removal between the bending portion 1542 and the connecting portion 1541 are simple and convenient, and since the bending portion 1542 and the connecting portion 1541 are a detachable split structure, the bending portion 1542 can be replaced according to needs in a specific implementation. Furthermore, the bending portion 1542 and the connecting portion 1541 are connected by screws (not shown) for further fixing.

[0052] See also Fig.11 Specifically, the limit block 152 is mounted on a mounting seat 1571, and the mounting seat 1571 is connected to the output shaft of the third driver 151. The third driver 151 drives the mounting seat 1571 to rise and fall, thereby causing the limit block 152 to rise and fall. The limit block 152 includes a mounting portion 1522 connected to the output end of the third driver 151 and a limit portion 1523 connected to the lower end of the mounting portion 1522. The limit portion 1523 is inclined from the mounting portion 1522 from top to bottom toward the first bending block 154, and the lower part of the limit portion 1523 faces one side of the first bending block 154 to form a vertical limit surface 1521. More specifically, the lower part of the limit portion 1523 protrudes toward the first bending block 154 from the side close to the first bending block 154 to increase the cross-sectional area of ​​the lower part of the limit block 152 in the horizontal direction, thereby increasing the area of ​​the limit block 152 against the upper surface of the FPC 410.

[0053] See also Fig.12 Specifically, the side pressure block 156 is installed on a mounting seat 1572, and the mounting seat 1572 is connected to the seat body 1574 through two flexible connectors 1573. The seat body 1574 is connected to the output shaft of the fifth driver 155. The fifth driver 155 drives the seat body 1574 to move linearly and link the two flexible connectors 1573, so that the mounting seat 1572 drives the side pressure block 156 to move to the bending portion 411 of the FPC 410. The setting of the flexible connector 1573 makes the side pressure block 156 and the FPC 410 in flexible contact, which can prevent damage to the FPC 410.

[0054] In this embodiment, the third driver 151, the fourth driver 153 and the fifth driver 155 are all mounted on a mounting frame 1575. Figure 7 Taking the angle shown as an example, the third driver 151 is installed on the upper left part of the mounting frame 1575, the fourth driver 153 is installed in the upper middle position of the mounting frame 1575, and the fifth driver 155 is installed on the upper right part of the mounting frame 1575, and the mounting frame 1575 is installed on a displacement module. The mounting frame 1575 can move horizontally driven by the displacement module, so as to fine-tune the position of the limit block 152, the first bending block 154 and the side pressure block 156 to adapt to the tolerance of the FPC 410. Among them, the third driver 151 and the fifth driver 155 are cylinders, and the fourth driver 153 is a motor, but it should not be limited to this. The third driver 151 is installed on the mounting frame 1575 from top to bottom and tilted to the right, and the mounting seat 1571 and the limit block 152 are both tilted to the right.

[0055] Specifically, the displacement module includes an X-axis module 1581 and a Y-axis module 1582. The X-axis module 1581 is arranged on the Y-axis module 1582. The mounting frame 1575 is installed on the X-axis module 1581.
