[0002] In the power lithium battery industry, in the module PACK assembly line field, to achieve more flexible production lines, submersible lifting AGVs are gradually replacing traditional roller conveyors. In this process, the submersible lifting AGV carries the pack and travels along a pre-set route, automatically stopping when it reaches the operating position and moving to the next position after completion. However, a problem arises: for automated workstations, it's necessary to ensure the incoming material height and level are consistent and that the material doesn't move during operation; this requires precise positioning when the AGV arrives at the automated workstation carrying the product. Currently, however, the submersible lifting AGV lacks a positioning device when transferring the pack to the automated workstation, causing problems with the equipment due to inconsistent incoming material postures. Utility Model Content

The two positioning components are respectively installed on the two positioning frames and respectively engage with the two locking devices to position the AGV transfer cart. The two lifting components are respectively installed on the two positioning frames and are used to lift the tray.

[0006] The structural design of this utility model's AGV transfer trolley positioning device achieves coarse positioning of the pallet by fixing the AGV transfer trolley with two positioning components, and then achieves fine positioning of the pallet by lifting the pallet with two lifting components. This ensures that the height and level of each incoming material in the automatic station are consistent, and also ensures that the pallet will not move.

Detailed Implementation

[0029] To facilitate understanding of this invention, a more comprehensive description of the invention will be provided below with reference to specific embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Currently, when a lurking lifting AGV transfer trolley transfers a pack to an automated workstation, there is no positioning device for positioning, which causes problems for the automated workstation equipment due to different incoming material postures. This embodiment proposes an AGV transfer trolley positioning device that can accurately position the AGV transfer trolley, achieving precise positioning of the pack's height and level, facilitating the automated workstation equipment to pick up and place packs.

[0032] Reference Figures 1-3 This embodiment provides an AGV transfer trolley positioning device for positioning the AGV transfer trolley 10, which includes two positioning frames 30, two positioning components 40 and two lifting components 50.

[0033] The AGV transfer cart 10 carries packs along a pre-set route to transfer them to an automated workstation where equipment processes the packs. To facilitate pack transfer, a tray 20 is installed above the AGV transfer cart 10 for placing the packs. Figure 4 The bottom of the tray 20 has four rectangularly arranged positioning posts 23, and the bottom of each positioning post 23 has positioning holes. Combined with... Figure 5 The AGV transfer cart 10 has four rectangularly arranged positioning pins 12 on its top. These pins 12 engage with the positioning holes of four positioning posts 23, allowing the AGV transfer cart 10 to move the pallet 20. To prevent packs from falling off during transport, four rectangularly arranged blocks are installed on the pallet 20. When placing a pack, the four corners of the pack are secured within these blocks, preventing it from falling off. The distance between the four blocks is adjustable to accommodate packs of different sizes.

[0034] To facilitate precise positioning of the AGV transfer cart 10 at the automated workstation, in this embodiment, locking devices are provided on both opposite sides of the AGV transfer cart 10. In this embodiment, the locking devices include two positioning blocks 11, combined with... Figure 6 The positioning block 11 has a triangular cross section.

[0035] Two positioning frames 30 are installed opposite each other at the automated work station. The distance between the two positioning frames 30 must ensure that the AGV transfer trolley 10 can enter between them.

[0036] Two positioning components 40 are respectively installed on two positioning frames 30. The two positioning components 40 can respectively engage with two locking devices on the AGV transfer cart 10, thereby positioning and fixing the AGV transfer cart 10. Figure 7In this embodiment, the positioning component 40 includes two positioning groups, which are respectively configured to correspond to the two positioning blocks 11 of the locking component. Each positioning group includes a positioning cylinder 41 and a limiting rod 42. The positioning cylinder 41 is mounted on the positioning frame 30, and its extension / retraction direction is consistent with the line connecting the two positioning frames 30. The limiting rod 42 is mounted on the extension / retraction end of the positioning cylinder 41, combined with… Figure 8 Two pins 43 are mounted on the limiting rod 42, and positioning wheels 44 are rotatably mounted on each of the two pins 43. The distance between the two positioning wheels 44 is adapted to the size of the positioning block 11 so that the positioning block 11 can be engaged between the two positioning wheels 44. Specifically, in conjunction with Figure 9 When the AGV transfer trolley 10 moves into position, each positioning group corresponds to its respective positioning block 11. At this time, the positioning cylinder 41 extends, driving the limit rod 42 to move closer to the AGV transfer trolley 10, and the positioning block 11 engages between the corresponding two positioning wheels 44. Furthermore, to ensure the precise movement of the limit rod 42, two guide rails 31 are installed on the positioning frame 30, and the limit rods 42 of the two positioning groups are respectively connected to the sliders of the two guide rails 31.

[0037] Two lifting components 50 are respectively mounted on two positioning frames 30. The two lifting components 50 can work together to lift the pallet 20 on the AGV transfer trolley 10 to a predetermined height to accommodate the operation of the automated workstation. In this embodiment, the lifting component 50 includes a lifting drive mechanism and a lifting frame 51. The lifting drive mechanism is mounted on the positioning frame 30, and a vertically arranged guide rail 32 is mounted on the positioning frame 30. The lifting frame 51 is connected to the slider of the guide rail 32. Thus, the lifting drive mechanism provides power to the lifting frame 51, enabling the lifting frame 51 to move vertically upward for lifting operations. The lifting frame 51 is provided with two horizontally arranged support plates 52. When the lifting frame 51 moves upward, it can drive the two support plates 52 to move upward, and the two support plates 52 can support the pallet 20 to lift the pallet 20 upward. To improve safety during the lifting process, in this embodiment, each pallet 52 is provided with a lifting block 53, which has a triangular cross-section. Correspondingly, a limit block 21 is provided at the bottom of the tray 20 at a position corresponding to each pallet 52. The limit block 21 has a limit groove 22 that matches the lifting block 53. Figure 10 During the lifting process, the pallet 52 can drive the lifting block 53 to engage in the limiting groove 22 of the corresponding limiting block 21, thereby preventing the pallet 20 from shaking during the lifting process and improving safety performance.

[0038] In this embodiment, the lifting drive mechanism includes a lifting cylinder 54 and two inclined sliders 55. The lifting cylinder 54 is mounted on the positioning frame 30; both inclined sliders 55 are slidably mounted on the positioning frame 30 and have inclined surfaces. The two inclined sliders 55 are connected by a connecting rod 57. One of the inclined sliders 55 is connected to the telescopic end of the lifting cylinder 54. The telescopic movement of the lifting cylinder 54 drives the corresponding inclined slider 55 to move horizontally back and forth, and the inclined slider 55 drives the other inclined slider 55 to move in the same direction through the connecting rod 57. Two rollers 56 are mounted on the lifting frame 51, and the two rollers 56 are always in rolling contact with the inclined surfaces of the two inclined sliders 55. When the lifting cylinder 54 is in the retracted state, the rollers 56 are in contact with the bottom end of the corresponding inclined surface. When the lifting cylinder 54 is in the extended state, the rollers 56 are in contact with the top end of the corresponding inclined surface. To facilitate the movement of the inclined slider 55, this embodiment provides two horizontally arranged guide rails 33 on the positioning frame 30 and on the same straight line. The two inclined sliders 55 are respectively connected to the sliders of the two guide rails 33. Proximity switches 34 for detecting the inclined sliders 55 are installed on the side of the positioning frame 30 where the two guide rails 33 are far apart from each other.

[0039] With the above structural setup, when the AGV transfer trolley 10 moves to the automatic workstation, it will automatically enter between the two positioning frames 30. After moving into position, the positioning cylinder 41 extends, causing the two positioning wheels 44 of the positioning group to engage with the corresponding positioning blocks 11, achieving coarse positioning of the pallet 20. Then, the lifting cylinder 54 extends, driving the two corresponding inclined sliders 55 to move, thereby pushing the lifting frame 51 upward. The lifting block 53 engages with the corresponding limit groove 22 and lifts the pallet 20 upward. At this time, the positioning post 2 at the bottom of the pallet 20... 3. Disengage from positioning pin 12, pallet 20 is suspended in the air. The moving distance of inclined slider 55 is obtained according to proximity switch 34, thereby determining the lifting height of pallet 20 and achieving precise positioning of pallet 20. When the automatic station finishes its operation, lifting cylinder 54 retracts, causing inclined slider 55 to move in the opposite direction. Lifting frame 51 descends, causing pallet 20 to descend. Positioning column 23 reconnects with positioning pin 12. Positioning cylinder 41 retracts, causing positioning wheel 44 to retract and separate from positioning block 11. At this time, AGV transfer trolley 10 carries pallet 20 to the next automatic station.

[0040] Furthermore, in this embodiment, multiple mounting plates 35 are provided at the bottom of each positioning frame 30 on the same horizontal plane. Two feet 36 are installed on each mounting plate 35. By adjusting the feet 36, the height of the positioning frame 30 can be adjusted, thereby adjusting the height of the positioning component 40 and the lifting component 50. This can adapt to AGV trolleys of different sizes and also adjust the height of the pallet 20 to match different automated workstations.
