Detailed Description

The present invention will be described in detail with reference to the accompanying drawings 1 to 5.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The utility model provides a battery walking device which has the advantages of simple and compact structure, easiness in assembly and maintenance, good stability, high walking efficiency and high transportation precision.

Referring to fig. 1, a schematic diagram of an embodiment of a stepper for a battery 400 is provided.

Specifically, the device comprises a frame 100, a transmission belt and a driving unit 300. Wherein, the conveyer belt 200 comprises transportation subassembly 210 and hold-in range 220, hold-in range 220 end to end constitutes the ring, the multiunit transportation subassembly 210 interval is even installs on hold-in range 220, forms conveyer belt 200 jointly.

Wherein the transport assembly 210 includes a follower 211, and the driving unit 300 includes a high-precision worm 310. The outer surface of the follower 211 may engage with the backlash structure 311 of the worm 310, as shown in the enlarged view of fig. 2. The axial direction of the worm 310 coincides with the conveyor belt 200.

The gap structure of the worm 310 can be simultaneously attached to a plurality of sets of the driven members 211, and through the rotation, the driven members 211 are driven to move along the axial direction of the worm 310, so that the corresponding transport assemblies 210 are moved, and the whole conveyor belt 200 is driven to move. Preferably, the follower 211 is disposed below the sides of either side of the transport assembly 210.

The device drives the conveyor belt 200 to move through the combination of the worm 310 and the driven piece 211. Due to the gap structure of the worm 310 with uniform spacing and good running performance, the conveyor belt 200 has better stability during the step. At the same time, the pitch and the running speed of the transport assembly 210 on the worm 310 are determined by the spacing between the gap structures thereof and the rotational speed. The gap structure can not be changed due to long-time use, so that the device has high walking efficiency and good transportation precision.

Preferably, the follower 211 is a bearing or a driven wheel with built-in bearing. The outer surface of the bearing or driven wheel is in line fit with the side surface of the gap structure, as shown in fig. 3. Based on the excellent transmission performance of the bearing, the whole device can be more durable and more precise in combination.

In some embodiments, the frame 100 includes side panels 110 and a support bracket 120, as shown in fig. 1.

An opening 112 is formed in the middle of the side plates 110, and a semi-closed annular space is formed between the two side plates 110 and the conveyor belt 200. Preferably, the openings 112 are further provided with i-shaped supporting plates at uniform intervals in the middle for improving the stability of the semi-closed structure.

The supporting frame 120 is provided with at least two groups on two sides of the conveyor belt 200, and a plurality of groups are uniformly arranged in the middle of the supporting frame according to the length of the whole step device, so as to support the conveyor belt 200. Preferably, the supporting plate comprises two supporting plates which are oppositely arranged, and a transverse plate is arranged between the two supporting plates and close to the ground, as shown in fig. 3.

Further, the side plate 110 is provided with a guide groove 111 near one side of the conveyor belt 200, as shown in fig. 3, and the rolling wheel 212 provided on the transportation assembly 210 moves along the guide groove 111 during the movement of the conveyor belt 200. The device improves the good directivity of the whole device in the walking process through the action of the guide groove 111 and the rolling wheel 212, so that the walking process is more stable. Preferably, the transportation assembly 210 is provided with two sets of rolling wheels 212 on the left and right.

Further, the worm 310 is arranged in the semi-closed installation space formed by the side plate 110 and the transmission belt, as shown in fig. 1. On one hand, the worm 310 is arranged in the installation space, so that the probability of contact with dust in the air can be reduced, and the influence of environment interference on the operation precision can be avoided. On the other hand, the worm 310 is dangerous in the rotation process, and the whole device is safer due to the built-in structure.

In order to realize transmission of the worm 310 and make the structure of the whole device more reasonable, the worm 310 is driven by the belt pulley 330. The pulley 330 enters the installation space through the opening 112 and is connected to the driving motor 320 located outside the frame 100.

Preferably, the driving unit 300 is disposed on the supporting frame 120, as shown in fig. 1, or may be disposed on the ground or other supporting objects in combination with the actual situation.

In some embodiments, the driving units 300 are arranged in one group or more than one group according to production requirements. When the transportation assembly 210 is arranged on the worm 310, the distance and the direction between the batteries 400 on the transportation assembly 210 cannot be changed, and the transportation assembly has the advantages of good precision, stable transportation and high efficiency. However, when the transporting assembly 210 is separated from the worm 310, the transporting precision and efficiency cannot be fully ensured due to the relaxation of the timing belt 220.

Therefore, in the present embodiment, in order to make the battery 400 meet the requirements of actual production in the step-sending process, the transportation precision and the transportation efficiency are provided with a plurality of sets. Since the transportation accuracy of the battery 400 is not required in all places of the conveyor belt 200, the high-accuracy worm 310 is not required in all places. Through the arrangement, the resource allocation can be more reasonable.

Further, the driving unit 300 may be provided with two or more worms 310, which are connected to adjacent worms by a flexible transmission shaft 340, as shown in fig. 4. Specifically, for a place with a close interval or a long transportation length, if a single worm 310 is arranged, the moment borne by the driving unit 300 is larger, and the equipment is damaged; if two sets of driving units 300 are used, the resources are wasted. Therefore, according to practical situations, one set of driving motor 320 can be used to drive two or more worms 310 to operate simultaneously, so that the driving motor 320 can be reused, resources are saved, and the load of equipment can be reduced.

In some embodiments, the timing belt 220 is provided with intermeshing teeth 213 at the connection of the transport assembly 210, as shown in fig. 5. If only adopt bolted connection, step send device in the transportation, the radial shear force of bolt is great, and the unstable condition of transmission appears easily. Therefore, in the embodiment, the toothed grooves 213 which are meshed with each other are arranged between the synchronous belt 220 and the conveying assembly 210, and the stressed area between the synchronous belt 220 and the conveying assembly is increased under the action of the toothed grooves 213, so that the stress is more uniform in the whole transmission process, and the transmission performance is better.

Further, the synchronous belt 220 is formed by splicing a plurality of belts, and the splicing position of the synchronous belt is located in the tooth slot 213. Specifically, if the synchronous belt 220 is integrally formed, it is easy to cause excessive fatigue during use, and is not beneficial to assembly and maintenance of the device. Therefore, the synchronous belt 220 has better tensile resistance by splicing, and is more convenient to assemble, maintain and maintain.

In some embodiments, the transportation assembly 210 includes a detachable V-shaped groove 214, on one hand, the V-shaped groove 214 can better limit the battery 400 during transportation; on the other hand, the detachable structure makes it easier to remodel the device. Therefore, the battery 400 is often updated, and different shapes and sizes of the battery 400 require different support brackets.

The present invention has been described in detail, and the principles and embodiments of the present invention have been described herein using specific examples, which are provided only to assist in understanding the present invention and the core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
