Then, the good product up and down drive module drives the two good product grippers 18 and the lithium battery 100 to move downwards to insert the lithium battery 100 into the clamping cavity and place it on the conveyor belt 24. Then, the good product gripper cylinder 17 drives the two good product grippers 18 to open to release the lithium battery 100. Then, the good product up and down drive module drives the two good product grippers 18 to move upwards to the initial position. In this way, the qualified lithium battery 100 on the battery mounting seat of the turntable is transferred to the unloading conveyor line 20. Then, the guide cylinder 281 drives the two guide clamps 282 to open and release the lithium battery 100. At this time, driven by the rotation of the conveyor belt 24, the lithium battery 100 can be moved towards the other end of the two unloading conveyor seats 21, thus realizing the conveying of the lithium battery 100. By inserting the lithium battery 100 into the clamping cavity, the lithium battery 100 will not tip over when placed on the conveyor belt 24.

The material gripping and loading structure 56 is located between the first material gripping and loading frame 51 and the second material gripping and loading frame 52, and is positioned on the side of the second translational linear module 55 near the unloading conveyor line 20. The first translational linear module 53 drives the module mounting plate 54 to reciprocate along the length direction of the first material gripping and loading frame 51 and the second material gripping and loading frame 52, thereby driving the second translational linear module 55 and the material gripping and loading structure 56 to reciprocate along the length direction of the first material gripping and loading frame 51 and the second material gripping and loading frame 52. The second translational linear module 55 drives the material gripping and loading structure 56 to reciprocate between the first material gripping and loading frame 51 and the second material gripping and loading frame 52 along the length direction of the second translational linear module 55. The first translational linear module 53 and the second translational linear module 55 have high precision and can provide precise linear motion for the material gripping and loading structure 56.

[0045] The material handling and loading structure 56 includes a first material handling and loading plate 57, a second material handling and loading plate 58, a lifting drive module, and multiple robotic arms 62. The first material handling and loading plate 57 is disposed on the side of the second translational linear module 55 near the unloading conveyor line 20. The second translational linear module 55 drives the first material handling and loading plate 57 to reciprocate along the length direction of the second translational linear module 55 between the first material handling and loading frame 51 and the second material handling and loading frame 52. When the second translational linear module 55 reciprocates along the length direction of the first material handling and loading frame 51 and the second material handling and loading frame 52, the second translational linear module 55 can drive the first material handling and loading plate 57 to reciprocate along the length direction of the first material handling and loading frame 51 and the second material handling and loading frame 52. The second material-gripping plate 58 is slidably disposed on the side of the first material-gripping plate 57 away from the second translational linear module 55. In this embodiment, a tray-loading slide rail 571 is provided on the side of the first material-gripping plate 57 away from the second translational linear module 55.

The first material-gripping plate 57 partially protrudes from the bottom end of the second translational linear module 55. A lifting drive module is disposed on the first material-gripping plate 57 and connected to the second material-gripping plate 58. Multiple robotic arms 62 are located below the second material-gripping tray 58 and are distributed sequentially at intervals along the length of the second material-gripping tray 58. Each robotic arm 62 is connected to the second material-gripping tray 58. A lifting drive module is used to drive the second material-gripping tray 58 to move up and down, thereby driving the multiple robotic arms 62 to move up and down. When the first material-gripping tray 57 reciprocates along the length of the second translational linear module 55, the first material-gripping tray 57 can drive the second material-gripping tray 58, the lifting drive module, and the multiple robotic arms 62 to reciprocate along the length of the second translational linear module 55. When the first material-gripping tray 57 reciprocates along the length of the first material-gripping tray frame 51 and the second material-gripping tray frame 52, the first material-gripping tray 57 can drive the second material-gripping tray 58, the lifting drive module, and the multiple robotic arms 62 to reciprocate along the length of the first material-gripping tray frame 51 and the second material-gripping tray frame 52. The multiple robotic arms 62 can grip multiple lithium batteries 100 on the feeding conveyor line 20 at one time and place multiple lithium batteries 100 into multiple placement slots of the material tray at one time, thereby improving production efficiency.

[0047] Furthermore, a variable-pitch drive module 61 is provided on the side of the second material gripping and loading plate 58 away from the first material gripping and loading plate 57. The movement of the second material gripping and loading plate 58 can drive the variable-pitch drive module 61 to move synchronously.

Specifically, the loading gripper cylinders 621 of the four robotic arms 62 are respectively connected to the variable-pitch drive module 61 through the aforementioned cylinder mounting seats 6211. The variable-pitch drive module 61 is used to drive the four robotic arms 62 to move away from each other at equal intervals or move closer to each other at equal intervals along the length direction of the second material gripping and loading plate 58, so as to increase or decrease the distance between two adjacent robotic arms 62, so as to adapt to lithium batteries 100 with different outer diameters and material trays with different spacing, thus having a wide range of applications.

The variable pitch cylinder 611 is located above the drive plate 612. The output end of the variable pitch cylinder 611 is connected to the side of the drive plate 612 away from the second material handling plate 58 through the connecting joint 6112. The variable pitch cylinder 611 is used to drive the drive plate 612 to move up and down.

[0049] Four robotic arms 62 are located below the drive plate 612. Among the four robotic arms 62, the tray-loading gripper cylinder 621 of the first robotic arm 62 and the tray-loading gripper cylinder 621 of the fourth robotic arm 62 are respectively connected to one side of the two first pitch blocks 613 through the aforementioned cylinder mounting base 6211. The tray-loading gripper cylinder 621 of the second robotic arm 62 and the tray-loading gripper cylinder 621 of the third robotic arm 62 are respectively connected to one side of the two second pitch blocks 614 through the aforementioned cylinder mounting base 6211. Two first pitch blocks 613 are symmetrical about the center line of the second material handling plate 58 in the height direction. The two first pitch blocks 613 are partially located between the drive plate 612 and the second material handling plate 58. The two first pitch blocks 613 are slidably disposed on the side of the second material handling plate 58 away from the first material handling plate 57 and can reciprocate along the length direction of the second material handling plate 58. Two first bearings 615 are respectively provided on one side of each of the two first pitch blocks 613. The drive plate 612 has two first strip holes 6121 corresponding to the two first bearings 615. The two first strip holes 6121 are symmetrical about the center line of the drive plate 612 in the height direction, and the upper ends of the two first strip holes 6121 are inclined towards the center line of the drive plate 612 in the height direction. The two first bearings 615 cooperate with the corresponding first strip holes 6121 and can move along the corresponding first strip holes 6121. The two second pitch blocks 614 are symmetrical about the center line of the height direction of the second material gripping plate 58. The two second pitch blocks 614 are located between the drive plate 612 and the second material gripping plate 58, respectively. The two second pitch blocks 614 are slidably disposed on the side of the second material gripping plate 58 away from the first material gripping plate 57 and can reciprocate along the length direction of the second material gripping plate 58. The two first pitch blocks 613 are provided with two clearance grooves 6131 at their close ends. The two clearance grooves 6131 are located below the two first bearings 615. The two second pitch blocks 614 are located between the two first pitch blocks 613 and the two second pitch blocks 614 are located in the two clearance grooves 6131. ​​Two second bearings 616 are provided on one side of the two second pitch blocks 614. The two second bearings 616 are located below the two first bearings 615 and correspond to the two clearance grooves 6131. The drive plate 612 is provided with two second strip holes 6122 corresponding to the two second bearings 616 and the two first strip holes 6121 respectively. The two second strip holes 6122 are symmetrical about the center line of the height direction of the drive plate 612, and the upper ends of the two second strip holes 6122 are inclined towards the center line of the height direction of the drive plate 612.The tilt angle and length of the first strip-shaped hole 6121 are greater than those of the second strip-shaped hole 6122. In this embodiment, the tilt angle of the first strip-shaped hole 6121 is 60 degrees, and the tilt angle of the second strip-shaped hole 6122 is 30 degrees. The two second strip-shaped holes 6122 are located below the two first strip-shaped holes 6121, and the upper ends of the two second strip-shaped holes 6122 correspond to the upper ends of the two first strip-shaped holes 6121, and the lower ends of the two second strip-shaped holes 6122 correspond to the centers of the two first strip-shaped holes 6121. The distance between the first strip-shaped hole 6121 and the corresponding second strip-shaped hole 6122 gradually increases along the centerline of the height direction away from the drive plate 612. The two second bearings 616 respectively cooperate with the corresponding second strip-shaped holes 6122 and can move along the corresponding second strip-shaped holes 6122. In the initial position, the two first bearings 615 are located inside the upper ends of the two first strip holes 6121, and the two second bearings 616 are located inside the upper ends of the two second strip holes 6122. At this time, the distance between two adjacent robotic arms 62 is the smallest. When it is necessary to increase the distance between two adjacent robotic arms 62, the drive plate 612 is first driven upward by the variable pitch cylinder 611, which in turn drives the two first bearings 615 to move towards the lower end of the corresponding first strip hole 6121, and the two second bearings 616 to move towards the lower end of the corresponding second strip hole 6122. The movement of the lower end of the strip hole 6122 causes the two first bearings 615 and the two second bearings 616 to move away from each other at equal intervals. This, in turn, causes the four robotic arms 62 to move away from each other at equal intervals, thus increasing the distance between the four robotic arms 62. When the two first bearings 615 are located at the lower ends of the two first strip holes 6121 and the two second bearings 616 are located at the lower ends of the two second strip holes 6122, the distance between two adjacent robotic arms 62 is at its maximum. When it is necessary to reduce the distance between two adjacent robotic arms 62, the drive plate 612 is first driven downward by the variable pitch cylinder 611. This causes the two first bearings 615 to move towards the upper end of the corresponding first strip hole 6121, and the two second bearings 616 to move towards the upper end of the corresponding second strip hole 6122. The movement of the two first bearings 615 and the two second bearings 616 can drive the two first variable pitch blocks 613 and the two second variable pitch blocks 614 to move closer to each other at equal intervals. This can drive the four robotic arms 62 to move closer to each other at equal intervals, thus reducing the distance between the four robotic arms 62.

Specifically, a second pitch-changing slide rail 585 is provided on the side of the second material-gripping plate 58 away from the first material-gripping plate 57.

[0053] In practical applications, the material tray is placed on the frame and located between the first material gripping and loading frame 51 and the second material gripping and loading frame 52, and below multiple robotic arms 62. First, the material gripping and loading structure 56 is moved above the unloading conveyor line 20 by the first translation linear module 53 and the second translation linear module 55, so that each robotic arm 62 corresponds to a lithium battery 100. Then, the multiple robotic arms 62 are driven to move downward by the lifting drive module so that the two loading claws 622 of each robotic arm 62 are located on both sides of the corresponding lithium battery 100. Then, the loading claw cylinder 621 of the robotic arm 62 drives the two loading claws 622 to close to clamp the corresponding lithium battery 100. Finally, the lifting drive module drives the multiple robotic arms 62 and the multiple lithium batteries 100 to move upward to the initial position. Then, the first translation linear module 53 and the second translation linear module 55 drive multiple robotic arms 62 and multiple lithium batteries 100 to be positioned above the material tray, with each lithium battery 100 corresponding to a placement slot on the material tray. Then, the lifting drive module drives the multiple robotic arms 62 and multiple lithium batteries 100 to move downwards to place the lithium batteries 100 at the bottom of the corresponding placement slots. Then, the loading gripper cylinder 621 of the robotic arm 62 drives the two loading grippers 622 to open to release the corresponding lithium batteries 100. Then, the lifting drive module drives the multiple robotic arms 62 to move upwards to the initial position. In this way, the lithium batteries 100 on the unloading conveyor line 20 are placed into the placement slots of the material tray.

[0054] This invention, through the configuration of a good product unloading component 10, a unloading conveyor line 20, a defective product unloading component 30, a defective product box 40, and a gripping and loading component 50, allows for the transfer of qualified lithium batteries 100 from the battery mounting base on the turntable to the unloading conveyor line 20 via the good product unloading component 10. The unloading conveyor line 20 then transports the qualified lithium batteries 100. Conversely, the defective product unloading component 30 transfers unqualified lithium batteries 100 from the battery mounting base on the turntable to the defective product box 40, thus ensuring the proper functioning of the defective products. The material box 40 collects defective lithium batteries 100, while the material handling and loading assembly 50 can place qualified lithium batteries 100 from the unloading conveyor line 20 into the placement slot of the material box. This enables automatic loading of qualified lithium batteries 100 from the battery mounting base on the turntable and automatic collection of defective lithium batteries 100 from the battery mounting base on the turntable into the defective material box 40. Compared with the existing manual method, this reduces the labor intensity, improves production efficiency, and reduces labor costs.
