Description

Technical Field

[0001] The utility model belongs to the technical field of battery swapping devices, and particularly relates to a high-precision stacker traveling positioning mechanism. Background Art

[0002] With the rapid development of the new energy vehicle industry, the demand for charging facilities is increasing day by day. As an important part of the charging mode, the operation efficiency and stability of the battery swapping station have a decisive impact on the user experience of new energy vehicles. In the operation of the battery swapping station, the stacker, as one of the key devices, is mainly responsible for the handling task of battery packs. To ensure the smoothness and safety of the battery swapping process, the traveling positioning accuracy of the stacker is particularly crucial.

[0003] The traveling positioning systems of traditional stackers mostly use guide rails and limit switches for positioning. However, in actual operation, due to the large weight of the battery pack, rubber-coated wheels are usually used for traveling, which may cause slipping during traveling, resulting in inaccurate positioning. Inaccurate positioning may lead to improper placement of the battery pack, thereby affecting the battery swapping efficiency and even causing equipment damage and safety accidents.

[0004] To overcome the above problems, the utility model proposes a high-precision stacker traveling positioning mechanism. Summary of the Utility Model

[0005] The main technical problem to be solved by the utility model is to provide a high-precision stacker traveling positioning mechanism, which can achieve precise control of the traveling position of the stacker, thereby improving the operation efficiency and safety of the battery swapping station.

[0006] To solve the above technical problems, a technical solution adopted by the utility model is:

[0007] A high-precision stacker traveling positioning mechanism includes a stacker main body, a track mechanism and a stacker positioning mechanism, and the stacker main body can move along the track mechanism;

[0008] The stacker positioning mechanism includes bearing seats respectively arranged at both ends of the moving direction of the stacker main body, bearings are respectively installed on the two bearing seats, drive sprockets are respectively installed on the two bearings, a drive chain is tensioned between the two drive sprockets, an encoder is installed on one of the bearings, a connecting plate fixedly connected with the drive chain is arranged on the stacker main body, and when the stacker main body moves, it drives the drive sprockets to convey in the same direction, thereby driving the drive sprockets to rotate and driving the encoder to rotate synchronously; for example, when the stacker main body moves to the left, the drive sprockets also convey to the left.

[0009] The stacker positioning mechanism further includes a chain tensioning adjustment assembly.

[0010] Further, a displacement sensor is provided at one end of the stacker main body, and a reflector is correspondingly provided at one end of the track mechanism.

[0011] Further, the track mechanism includes a stacker overhead rail and a stacker ground rail which are arranged parallel to each other vertically.

[0012] Further, walking wheels are respectively provided at the upper and lower ends of the stacker main body corresponding to the stacker overhead rail and the stacker ground rail.

[0013] Further, the stacker positioning mechanism is located on one side of the stacker ground rail.

[0014] Further, anti-collision blocks are respectively provided at both ends of the stacker ground rail.

[0015] Further, the chain tension adjusting assembly includes an adjusting plate provided on one side of the bearing seat. The adjusting plate is fixedly provided, and an adjusting bolt is threadedly connected to the adjusting plate. One end of the adjusting bolt facing the bearing seat is rotatably connected to the bearing seat. By rotating the adjusting bolt, the distance between the bearing seat and the adjusting plate can be adjusted.

[0016] The beneficial technical effects of the present utility model are as follows:

[0017] The traveling position of the stacker is judged by the displacement sensor. When the stacker main body moves, it will drive the drive chain to move forward and backward.

The following embodiments are used to illustrate the present utility model, but do not limit the scope of the present utility model.

[0030] This specific embodiment discloses in detail a high-precision stacker traveling positioning mechanism. As Figures 1 to 6 shown, it includes a stacker main body 1, a rail mechanism 2, and a stacker positioning mechanism 3. The stacker main body 1 can move along the rail mechanism 2. The rail mechanism 2 includes a stacker overhead rail 21 and a stacker ground rail 22 which are arranged parallel up and down. The stacker positioning mechanism 3 is located on one side of the stacker ground rail 22. The stacker positioning mechanism 3 includes bearing seats 31 respectively arranged at both ends in the moving direction of the stacker main body 1. Two bearing seats 31 are respectively installed with bearings 32, and two bearings 32 are respectively installed with driving sprockets 33. A driving chain 34 is tensioned between the two driving sprockets 33. One of the bearings 32 is installed with an encoder 35, and the stacker main body 1 is provided with a connecting plate 36 fixedly connected to the driving chain 34.

[0031] In order to ensure the tension of the driving chain 34, a chain tension adjusting assembly is designed to adjust the tension of the driving chain 34. The chain tension adjusting assembly includes an adjusting plate 371 arranged on one side of the bearing seat 31. The adjusting plate 371 is fixedly arranged on the ground, and an adjusting bolt 372 is threadedly connected to the adjusting plate 371. One end of the adjusting bolt 372 facing the bearing seat 31 is rotatably connected to the bearing seat 31. By rotating the adjusting bolt 372, the distance between the bearing seat 31 and the adjusting plate 371 can be adjusted.

[0032] A displacement sensor 41 is provided at one end of the stacker main body 1, and a reflector 42 is correspondingly provided at one end of the track mechanism 2. The displacement sensor 41 and the reflector 42 are used in cooperation to accurately measure the traveling position of the stacker main body 1, thereby further improving the positioning accuracy.

[0033] In this specific embodiment, traveling wheels 11 are respectively provided at the upper and lower ends of the stacker main body 1 corresponding to the stacker overhead rail 21 and the stacker ground rail 22. The traveling wheels 11 are closely matched with the track mechanism 2 to ensure the stability and accuracy of the stacker main body 1 during movement.

[0034] Anti-collision blocks 221 are respectively provided at both ends of the stacker ground rail 22 to prevent the stacker main body 1 from exceeding the predetermined track range during traveling, thereby avoiding possible collision accidents.

[0035] It should be noted that how the stacker main body realizes movement is not the technical problem to be solved by the present utility model, so it will not be elaborated here.

[0036] The working principle of the present utility model:

[0037] The traveling position of the stacker is judged by the displacement sensor. The movement of the stacker main body will drive the transmission chain to move forward and backward. The movement of the transmission chain will further cause the transmission sprocket to rotate, and the rotation of the transmission sprocket will drive the encoder to rotate. The encoder is used to confirm the traveling position of the stacker. Through the dual confirmation mechanism of the displacement sensor and the encoder, the accuracy of the traveling position of the stacker is ensured.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0039] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "setting" should be understood in a broad sense.
