DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0034] The following is combined with Figure 1-8 This application is described in further detail.

[0035] The embodiment of the present application discloses an automated battery cell sorting and stacking device. Figure 1 The automated battery cell sorting and stacking device includes an incoming material conveyor line 1, a first gripping mechanism 2, a sorting conveyor line 3, and a second gripping mechanism. The incoming material conveyor line 1 is used to convey battery cells 100; the first gripping mechanism 2 is used to grip and transfer battery cells 100 from the incoming material conveyor line 1; the sorting conveyor line 3 is used to receive battery cells 100 from the first gripping mechanism 2 and arrange them; and the second gripping mechanism includes a multi-degree-of-freedom robot 4, a battery cell gripping assembly 5, and a support gripping assembly 6. Both the battery cell gripping assembly 5 and the support gripping assembly 6 are connected to the active end (i.e., the robotic arm) of the multi-degree-of-freedom robot 4. The battery cell gripping assembly 5 is used to transfer battery cells 100 from the sorting conveyor line 3 in batches, and the support gripping assembly 6 is used to grip and stack support members to facilitate the placement of the battery cells 100.

[0036] When in use, the multi-degree-of-freedom robot 4 drives the battery cell grabbing assembly 5 to move, so as to grab the battery cells 100 in the material conveyor line 3 in batches and place them in the supporting parts; in addition, the multi-degree-of-freedom robot 4 drives the supporting part grabbing assembly 6 to move, so as to place the supporting parts in the preset battery cell 100 stacking area, or stack the supporting parts on the supporting parts full of battery cells 100, so as to realize the automatic stacking of the battery cells 100.

[0037] Further, such as Figure 2-3 As shown, the first grasping mechanism 2 includes a first clamping jaw 2-1 and a displacement assembly. The first clamping jaw 2-1 is used to take out the discharge core 100, and the displacement assembly is used to drive the first clamping jaw 2-1 to move.

[0038] Furthermore, in this embodiment, the displacement assembly preferably employs a gantry robot, which drives the first gripper 2-1 to perform multi-degree-of-freedom motion to perform the pick-and-place operation of the battery cells 100. The use of a gantry robot effectively utilizes workshop space, improves the efficiency of transferring battery cell 100 materials, and matches the gripping rhythm of the second gripping mechanism.

[0039] Specifically, if Figure 2 As shown, in some embodiments, the gantry truss robot includes a lateral displacement module 2-2, a longitudinal displacement module 2-3 and a vertical displacement module 2-4. Among them, the lateral displacement module 2-2 is installed horizontally on the vertical pole, and two are installed side by side. The lateral displacement module 2-2 is used to provide lateral displacement; the longitudinal displacement module 2-3 is installed longitudinally at the movable ends of the two lateral displacement modules 2-2 to provide longitudinal displacement; the vertical displacement module 2-4 is installed at the movable end of the longitudinal displacement module 2-3 to provide vertical displacement. The first clamp 2-1 is finally installed at the movable end of the vertical displacement module 2-4. The types of the lateral displacement module 2-2, the longitudinal displacement module 2-3 and the vertical displacement module 2-4 can be various, as long as they can jointly realize the multi-directional displacement adjustment of the first clamp 2-1.

[0040] For ease of understanding, taking the lateral displacement module 2-2 as an example, in some embodiments, the lateral displacement module 2-2 includes a base and a slide. A rack is mounted on the base; the slide is slidably mounted on the base, and is preferably guided by pulleys and rails; a motor is mounted on the slide, and a gear is mounted on the output end of the motor, and the gear meshes with the rack. The motor drives the gear to rotate, causing the slide to move linearly. Preferably, the motor outputs power through a bidirectional output reducer. Similarly, the remaining longitudinal displacement modules 2-3 and vertical displacement modules 2-4 can adopt a design similar to that of the lateral displacement module 2-2.

[0041] Of course, in other embodiments, the displacement component may also be a multi-joint manipulator or other structure or device.

[0042] Further, such as Figure 3As shown, the first gripper 2-1 includes, but is not limited to, a pneumatic gripper, the teeth of which are adapted to the size of a single battery cell 100. Preferably, the clamping surface of the first gripper 2-1 is provided with a buffer layer 2-5, which includes, but is not limited to, a silicone sheet. The provision of the buffer layer 2-5 reduces the impact of the gripping process, enabling accurate and efficient gripping of a single battery cell 100 while preventing the cell 100 from being damaged by rigid contact and contamination.

[0043] Furthermore, at the material handling conveyor line 3, the first gripping mechanism 2 completes the transfer of the single battery cell 100 from the incoming material conveyor line 1 to the material handling conveyor line 3. As a preferred embodiment, Figure 4 As shown, the material handling conveying line 3 includes a conveyor 3-1 and a side guard structure. The side guard structure is arranged above the conveying surface of the conveyor 3-1. A plurality of parallel battery cell guide channels 200 are formed in the side guard structure, and the guide entrance of the battery cell guide channel 200 faces the feed end of the conveyor 3-1.

[0044] Specifically, the conveyor 3 - 1 is preferably a belt conveyor, which is driven by a motor and transports the battery cells 100 via a belt.

[0045] Specifically, the baffle structure preferably uses roller ribs to group the battery cells 100. Figure 4 As shown, the baffle structure includes a horizontal plate 3-2 and a guide plate 3-4 with rollers 3-3 on top. The horizontal plate 3-2 is fixedly connected to the frame of the conveyor 3-1 and is arranged horizontally above the conveying surface of the conveyor 3-1. A plurality of guide plates 3-4 are arranged side by side above the conveying surface of the conveyor 3-1. The length direction of the plurality of guide plates 3-4 is consistent with the conveying direction of the conveyor 3-1. The ends of the plurality of guide plates 3-4 away from the feeding end of the conveyor 3-1 are connected to the horizontal plate 3-2 to form a plurality of parallel battery cell guide channels. In the guide plate 3-4, a plurality of rollers 3-3 are arranged along the length direction of the guide plate 3-4, and the rotation axis of the rollers 3-3 is vertical. The rollers 3-3 on two adjacent guide plates 3-4 can jointly guide and transport the battery cells 100.

[0046] Under this design, under the joint action of the sidewall structure and the conveyor 3-1, the battery cells 100 can be automatically divided into groups, and the battery cells 100 can be conveyed in groups, which is convenient for information management and the subsequent second grasping mechanism to grasp the battery cells 100 for stacking to adapt to the subsequent placement of the battery cells 100.

[0047] Of course, in some embodiments, in order to save costs, the roller 3 - 3 may not be provided on the guide plate 3 - 4 , and the guide plate 3 - 4 may be used directly for guiding and grouping the battery cells 100 .

[0048] After the battery cells 100 are grouped and arranged in the material handling conveyor line 3 , the battery cells 100 are grabbed in batches by the second grabbing mechanism to transfer the battery cells 100 in the material handling conveyor line 3 to a preset battery cell stacking area for automatic stacking of the battery cells 100 .

[0049] Furthermore, the multi-degree-of-freedom robot 4 includes but is not limited to a six-axis robot, which transfers and stacks the battery cells 100 in groups on the material conveyor line 3. The six-axis robot has flexible movements, suitable loads, and an arm span that meets the requirements. While accelerating the grabbing rate of the battery cells 100, it can improve the accuracy and stability of the grabbing and stacking process of the battery cells 100, effectively improving the transportation, storage and stacking efficiency of the battery cells 100.

[0050] Specifically, if Figure 5 As shown, in this embodiment, the battery cell gripping assembly 5 includes a mounting base and a second gripper 5-1. The mounting base is connected to the movable end of the multi-degree-of-freedom robot 4 via an adapter flange. Multiple second grippers 5-1 are mounted side by side on the mounting base to grasp battery cells 100 in batches. The number of second grippers 5-1 preferably matches the number of battery cells 100 in the material handling conveyor line 3 to ensure a stable cycle time.

[0051] Furthermore, the specific form of the second gripper 5-1 can be the same as that of the first gripper 2-1, and preferably, a corresponding laser sensor and a beam switch are installed above each second gripper 5-1 (i.e., at the mounting base) to identify and grasp the finished battery cells 100 on the material sorting conveyor line 3. The operating principles of the laser sensor and beam switch are prior art and will not be elaborated on here. It is understood that a corresponding laser sensor and beam switch can also be provided for the first gripper 2-1.

[0052] The mounting seat can be a hard seat or a combined seat with a buffering and shock absorbing function. For example, when selecting a combined seat, Figure 6 As shown, the combined base includes a base plate 5-2, a buffer structure and a mounting plate 5-3. In this design, the base plate 5-2 is connected to the mounting plate 5-3 through the buffer structure, and the base plate 5-2 is connected to the multi-degree-of-freedom robot 4, and the mounting plate 5-3 is connected to the plurality of second clamps 5-1. Preferably, the buffer structure includes a linear bearing 5-4 and a buffer spring 5-5, the linear bearing 5-4 is connected to the mounting plate 5-3, and the inner ring of the linear bearing 5-4 is equipped with a guide rod 5-6, which passes through the top of the base plate 5-2 and is fixed to the base plate 5-2, so that the mounting plate 5-3 can only move on the base plate 5-2 in a straight line toward and away from the base plate 5-2, and the buffer spring 5-5 is connected between the base plate 5-2 and the mounting plate 5-3 to alleviate the impact.

[0053] Of course, in other embodiments, the buffer structure can be replaced by a damper, an elastic pad, an elastic telescopic rod, etc., in various forms, and can be selected according to needs.

[0054] Further, such as Figure 7 As shown, the support member grabbing assembly 6 preferably employs a cylinder-driven clamp. Specifically, the support member grabbing assembly 6 comprises a base 6-1 and two linear actuators 6-2 mounted on the base 6-1. The driving ends of the two linear actuators 6-2 are disposed facing each other and are each equipped with a clamping arm 6-3. The two linear actuators 6-2 can drive the two clamping arms 6-3 toward or away from each other to achieve gripping and releasing of the support member. The linear actuators 6-2 include, but are not limited to, cylinders.

[0055] Furthermore, the device also includes a positioning mechanism 7 for positioning the supporting member in the stacking area of ​​the battery cells 100.

[0056] Specifically, if Figure 8 As shown, the positioning mechanism 7 includes a positioning plate 7-1 and a drive assembly 7-2. Two positioning plates 7-1 are provided at intervals. The drive assembly 7-2 is used to adjust the distance between the two positioning plates 7-1 to position the supporting member between the two positioning plates 7-1. The drive assembly 7-2 includes but is not limited to a cylinder.

[0057] Furthermore, in some embodiments, the positioning mechanism 7 also includes two connecting plates 7-3, which are arranged side by side and at both ends of the positioning plate 7-1. Both ends of the connecting plates 7-3 in the length direction are protruded with connecting rods 7-4, and the two ends of the connecting plates 7-3 in the length direction are respectively hinged to the positioning plate 7-1 through the connecting rods 7-4, so that the connecting plates 7-3 and the positioning plate 7-1 form a parallelogram-shaped connecting rod mechanism, so that the connecting plates 7-3 are used to assist in the positioning of the supporting member.

[0058] Preferably, a support base 10 with a platform can be used as the installation base of the positioning mechanism 7, so that the staff can plan the stacking area according to the needs and then place the positioning mechanism 7 at the target stacking position.

[0059] Furthermore, the supporting member can be a tray 8 or a partition 9 with multiple slots. The slots can be provided on a single side or multiple sides of the partition 9. For example, a tray 8 can be used as the stacking base for the battery cells 100, a partition 9 with a slot on a single side can be used as the bottom support member for the battery cells 100, and a partition 9 with slots on both sides can be used as the upper support member.

[0060] Further, such as Figure 1As shown, a safety fence 11 is provided around the cell stacking area. By providing the safety fence 11, the stacking area can be effectively divided and protected to prevent people from entering by mistake, avoid accidents in the working area of ​​the six-axis robot during stacking, and improve the safety of stacking.

[0061] Furthermore, the device also includes a control module, which is connected to the incoming material conveyor line 1, the first grabbing mechanism 2, the material sorting conveyor line 3 and the second grabbing mechanism, etc., to control the operation and rhythm of each mechanism.
