Description

Technical Field

[0001] This utility model relates to the field of battery casing processing technology, and in particular to an automatic palletizing device. Background Technology

[0002] The battery casing is a crucial component of a battery. Its primary function is to protect the battery's internal chemical substances and electrode structure, preventing damage from external environmental factors such as moisture, dust, and impacts. Simultaneously, the battery casing needs to possess sufficient mechanical strength to withstand potential collisions and compression.

[0003] After processing, battery casings need to be neatly stacked in sub-baskets (containers for holding battery casings). The conventional stacking method uses a robotic arm palletizer to pick up the battery casings and place them into the sub-baskets. However, robotic arm palletizers have poor adaptability to irregularly shaped materials, especially cylindrical battery casings. The smooth and curved outer surface of the battery casings can easily cause the robotic arm to fail to grasp them, requiring frequent manual adjustments, which also affects stacking efficiency. Moreover, although the conventional stacking method can stack battery casings in batches in the sub-baskets, the capacity of the sub-baskets is limited. Each time a sub-basket is filled, it needs to be manually lifted away, and an operator needs to simultaneously put in an empty sub-basket to continue stacking. With a large output of battery casings, manual operation is not only time-consuming, labor-intensive, and costly, but the time spent changing sub-baskets also takes up time, affecting stacking efficiency. Utility Model Content

[0004] This invention provides an automatic palletizing device that can solve the problem of low palletizing efficiency of battery casings mentioned in the background art.

[0005] An automatic palletizing device is installed inside a battery casing processing equipment, comprising: a gripping mechanism movable in the X direction, the gripping mechanism including a plurality of liftable flexible suction cups, the flexible suction cups being used for vacuum negative pressure adsorption of the battery casing; Below the gripping mechanism are a first conveyor belt and a liftable second conveyor belt. Several sub-baskets stacked along the Z direction can be set on the first conveyor belt. The battery casing processing equipment is equipped with a moving mechanism, which is used to move the sub-baskets on the first conveyor belt from top to bottom to the second conveyor belt.

[0006] Preferably, the gripping mechanism includes a lift, the lift is connected to a mounting frame, and the mounting frame is provided with a plurality of the flexible suction cups.

[0007] Preferably, several of the flexible suction cup arrays are distributed.

[0008] Preferably, the moving mechanism includes a slide rail, the slide rail being slidably connected to a connecting frame, and the connecting frame being connected to a pushing assembly.

[0009] Preferably, the pushing assembly includes a protective frame, which is fixedly mounted on the connecting frame.

[0010] Preferably, the protective frame is a box structure with an opening on one side and a closed side.

[0011] Preferably, a cylinder is fixedly installed on the closed side of the protective frame, and a push plate is fixedly installed at the output end of the cylinder.

[0012] Preferably, the battery casing processing equipment is further provided with a positioning mechanism, which includes a motor, a rotating shaft fixedly installed at the output end of the motor, and a fixed frame rotatably connected to one end of the rotating shaft through a bearing.

[0013] Preferably, the rotating shaft is fixedly mounted with a plurality of positioning rods.

[0014] Preferably, the positioning rods are arranged at equal intervals along the length of the rotating shaft, and the positioning rods are located in the same plane.

[0015] The beneficial effects of this utility model are: In this automatic palletizing device, the gripping mechanism moves along the X direction and moves the battery casing into the sub-basket after being adsorbed by the flexible suction cup. It only needs to ensure that the adsorption surface of the battery casing is flat, which replaces the robotic arm gripping operation in the prior art, reduces the restriction on the shape of the battery casing, eliminates the need for real-time manual adjustment, and improves the palletizing efficiency of the battery casing.

[0016] The sub-baskets on the first conveyor belt are moved from top to bottom to the second conveyor belt by the moving mechanism inside the battery casing processing equipment. The height of the second conveyor belt is adjusted according to the position of the top sub-basket on the first conveyor belt. This allows for batch movement of the filled sub-baskets, enabling operators to intermittently lift the sub-baskets conveyed by the second conveyor belt and move the empty sub-baskets on the first conveyor belt without frequent manual handling. This reduces labor costs and improves the stacking efficiency of battery casings. Attached Figure Description

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figure 1 , Figure 11 As shown, this utility model proposes an automatic palletizing device, which is installed inside a battery casing processing equipment 3. A punch press 1 is installed on one side of the battery casing processing equipment 3, and a feeder 2 is installed between the punch press 1 and the battery casing processing equipment 3. The feeder 2 transports the battery casings punched by the punch press 1 to the battery casing processing equipment 3 for processing. After processing steps such as rotary cutting, drying, and visual inspection, the final good products will enter the palletizing process. During palletizing, the battery casings need to be placed in the workstations of the sub-baskets. The battery casing is a cylindrical structure that is closed at one end and open at the other end.

[0021] like Figures 2-4As shown, the automatic palletizing device includes a positioning mechanism 4, which is disposed within the battery casing processing equipment 3. The positioning mechanism 4 includes a motor 41, which is fixed within the battery casing processing equipment 3. A rotating shaft 43 is fixedly mounted on the output end of the motor 41, and one end of the rotating shaft 43 is rotatably connected to a fixing frame 42 via a bearing. The fixing frame 42 is fixed within the battery casing processing equipment 3.

[0022] The rotating shaft 43 is fixedly equipped with several positioning rods 44 to facilitate batch positioning of the battery casings. The positioning rods 44 are arranged at equal intervals along the length of the rotating shaft 43 and are located in the same plane.

[0023] In this embodiment, within the battery casing processing equipment 3, when the battery casing flows to the corresponding positioning rod 44, the push rod 31 within the battery casing processing equipment 3, driven by a drive structure (including but not limited to a linear motor and a hydraulic cylinder), pushes the closed end of the battery casing onto the positioning rod 44. Then, the motor 41 drives the rotating shaft 43 to rotate, and the rotating shaft 43 drives the positioning rod 44 to rotate until the battery casing on the positioning rod 44 rotates to an upright position in the vertical plane.

[0024] like Figure 2 , Figure 5 As shown, the automatic palletizing device also includes a gripping mechanism 5. A track (not shown) is provided inside the battery casing processing equipment 3, and the gripping mechanism 5 is mounted on the track. The track provides a moving path for the gripping mechanism 5 in the X direction, enabling the gripping mechanism 5 to move along the X direction.

[0025] Specifically, such as Figure 6 As shown, the gripping mechanism 5 includes a lift 51, which is connected to a mounting frame 52. The mounting frame 52 is equipped with several flexible suction cups 53, which are arranged in an array to facilitate the batch adsorption of battery casings. In this embodiment, the flexible suction cups 53 can adsorb 15 battery casings at a time, which is compatible with the three columns and five rows of workstations in the sub-basket. The flexible suction cups 53 are connected to an external vacuum system for vacuum negative pressure adsorption of the closed ends of the battery casings.

[0026] like Figures 2-3 As shown, two conveying mechanisms are arranged below the gripping mechanism 5, namely the first conveying mechanism and the second conveying mechanism. The first and second conveying mechanisms have the same structure, both consisting of a frame, drive wheels, and conveyor belts, with the conveyor belts of the two conveying mechanisms moving in opposite directions. The frame of the second conveying mechanism is also connected to a lifting device, which includes, but is not limited to, a screw jack and a hydraulic cylinder. In this embodiment, a screw jack is used as the lifting device, which can drive the second conveying mechanism to rise and fall.

[0027] The first conveyor mechanism has a first conveyor belt 7, and the second conveyor mechanism has a second conveyor belt 8. Several sub-baskets stacked along the Z-direction can be installed on the first conveyor belt 7.

[0028] like Figures 2-5 , Figures 7-8 As shown, the battery casing processing equipment 3 is equipped with a moving mechanism 6, which is used to move the sub-baskets on the first conveyor belt 7 from top to bottom to the second conveyor belt 8.

[0029] Specifically, the moving mechanism 6 includes a slide rail 61, which is fixedly installed on the battery casing processing equipment 3. A connecting frame 62 is slidably connected to the slide rail 61, and the connecting frame 62 is connected to the pushing assembly 63. The pushing assembly 63 includes a protective frame 631, which is fixedly installed on the connecting frame 62. The protective frame 631 is a box structure with one open side and one closed side. A cylinder 632 is fixedly installed on the closed side of the protective frame 631, and a push plate 633 is fixedly installed at the output end of the cylinder 632. The push plate 633 can extend from the open end of the protective frame 631 under the action of the cylinder 632 to push the sub-basket.

[0030] like Figures 5-6 As shown, Figure 9 , Figure 11 As shown, during palletizing, the bottom height of the uppermost sub-basket on the second conveyor belt 8 is flush with the bottom height of the uppermost sub-basket on the first conveyor belt 7. The gripping mechanism 5 moves along the X direction to directly above the positioning mechanism 4. At this time, the battery casing sleeved on the positioning rod 44 has rotated to a vertical position. The lifting platform 51 drives the mounting frame 52 to descend until the flexible suction cup 53 adheres to the closed end of the battery casing. Then, the lifting platform 51 drives the flexible suction cup 53 to move upward. Next, the gripping mechanism 5 moves along the X direction to directly above the first conveyor belt 7. The lifting platform 51 drives the flexible suction cup 53 to move downward again until the battery casing falls into the corresponding position in the sub-basket. When the uppermost sub-basket on the first conveyor belt 7 is filled, the pushing component 63 moves to the height of the center of gravity of the uppermost sub-basket. The cylinder 632 drives the push plate 633 to move, and the push plate 633 pushes the uppermost sub-basket onto the second conveyor belt 8. At this point, the original second-layer sub-basket on the first conveyor belt 7 becomes the top-layer sub-basket. The filling and pushing steps are repeated. During this period, the height of the second conveyor belt 8 needs to be adjusted to keep the top of the top-layer sub-basket on the second conveyor belt 8 level with the bottom of the top-layer sub-basket on the first conveyor belt 7, until all the sub-baskets on the first conveyor belt 7 are filled and pushed onto the second conveyor belt 8, and the battery casings are stacked.

[0031] It should be noted that during the entire palletizing process, both the first conveyor belt 7 and the second conveyor belt 8 are stopped. Conveying only occurs when empty sub-baskets are placed on the first conveyor belt 7 and when the second conveyor belt 8 is unloaded (after all the filled sub-baskets are conveyed out of the battery casing processing equipment 3).

[0032] In this application, since the flexible suction cup 53 is used to perform vacuum negative pressure adsorption on the battery casing, it is only necessary to ensure that the adsorption surface of the battery casing (i.e. the closed end of the battery casing) is flat. This replaces the robotic arm gripping operation in the prior art, reduces the limitation on the shape of the battery casing, eliminates the need for real-time manual adjustment, and improves the palletizing efficiency.

[0033] In addition, by moving the sub-baskets on the first conveyor belt 7 from top to bottom to the second conveyor belt 8 through the moving mechanism 6, the filled sub-baskets can be moved in batches. This allows operators to intermittently lift the sub-baskets conveyed by the second conveyor belt 8 and fill the empty sub-baskets on the first conveyor belt 7 without frequent handling. This reduces labor costs and improves the stacking efficiency of battery casings.

[0034] Working principle: During palletizing, the bottom height of the uppermost sub-basket on the second conveyor belt 8 is aligned with that on the first conveyor belt 7. The gripping mechanism 5 moves along the X-axis to directly above the positioning mechanism 4. At this time, the battery casing fitted on the positioning rod 44 has rotated to an upright position in the vertical plane. The lifting platform 51 drives the mounting frame 52 to descend until the flexible suction cup 53 adheres to the closed end of the battery casing. Then, the lifting platform 51 drives the flexible suction cup 53 to move upward. Next, the gripping mechanism 5 moves along the X-axis to directly above the first conveyor belt 7. The lifting platform 51 drives the flexible suction cup 53 to move downward again until the battery casing falls into the corresponding position in the sub-basket. When the uppermost sub-basket on the first conveyor belt 7 is filled, the pushing component 63 moves to the height of the center of gravity of the uppermost sub-basket. The cylinder 632 drives the push plate 633 to move, and the push plate 633 pushes the uppermost sub-basket onto the second conveyor belt 8. At this point, the original second-layer sub-basket on the first conveyor belt 7 becomes the top-layer sub-basket. The filling and pushing steps are repeated until all the sub-baskets on the first conveyor belt 7 are filled and pushed onto the second conveyor belt 8, and the battery casings are stacked.

[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
