However, as each transfer device is only suitable for battery components with the same specifications and dimensions and cannot automatically adapt to products of different sizes, it is required to manually change the transfer device for changeover of products, resulting in low production efficiency.
An objective of the present application is to provide a transfer device, which is configured to automatically adapt to pieces-to-be-transferred having different specifications and sizes, and is conducive to improvement in production efficiency during changeover.

The first limiting assembly 60 and the second limiting assembly 70 are configured to fix two ends of the piece-to-be-transferred in the second direction, such that the piece-to-be-transferred is relatively fixed relative to the positioning platform 20 in the second direction.
After the first locking assembly 30 and the second locking assembly 40 fix two ends of the piece-to-be-transferred in the first direction in the horizontal plane, the first limiting assembly 60 and the second limiting assembly 70 may be driven by the second driving assembly 80 to clamp two ends of the piece-to-be-transferred in the second direction, so as to improve stability of the piece-to-be-transferred in a transfer process. In addition, the first limiting assembly 60 and the second limiting assembly 70 may be driven by the second driving assembly 80 to move toward or away from each other, so as to adjust a distance between the first limiting assembly 60 and the second limiting assembly 70 in the second direction, such that the first locking assembly 30 and the second locking assembly 40 cooperate to fix pieces-to-be-transferred having different specifications and sizes.
According to some embodiments of the present application, the second driving assembly 80 includes a second driving member (not shown in figures) and a second transmission assembly connected to the second driving member, and the second transmission assembly is connected to the first limiting assembly 60. The second driving member is configured to drive the second transmission assembly to move, so as to drive the first limiting assembly 60 to move in the direction toward or away from the second limiting assembly 70.
As an example, the second driving member is an electric motor, and the second transmission assembly is a ball screw structure.
It can be understood that the first limiting assembly 60 is a movable assembly, and the second limiting assembly 70 is a fixed assembly. Certainly, the second transmission assembly may be connected to the first limiting assembly 60 and the second limiting assembly 70, so as to drive the first limiting assembly 60 and the second limiting assembly 70 to move at the same time.
When the second driving member drives the second transmission assembly to move, the first transmission assembly may drive the first limiting assembly 60 to move in the direction toward or away from the second limiting assembly 70, such that the first limiting assembly and the second limiting assembly 70 cooperate to clamp two ends of the piece-to-be-transferred in the second direction.
With reference to
Two ends of the second lead screw 81 are in rotating connection to the positioning platform 20, the second lead screw 81 is perpendicular to the first lead screw 51, and the second lead screw 81 is arranged at a different height from the first lead screw 51.
Since the third spiral transmission member 82 is connected to the first limiting assembly 60, when the second driving member drives the second lead screw 81 to rotate, the third spiral transmission member 82 may drive the first limiting assembly 60 to reciprocate in the second direction. Therefore, the distance between the first limiting assembly 60 and the second limiting assembly 70 may be adjusted, so as to fix pieces-to-be-transferred having different lengths in the second direction in an adjustable manner.

With reference to
The third connecting plate 65 is connected to the third spiral transmission member 82, the fifth slide block 63 and the sixth slide block 64 such that the third connecting plate may be driven by the third spiral transmission member 82 to reciprocate in the second direction relative to the fifth slide rail 61 and the sixth slide rail 62. The at least one first limiting block 66 is arranged on the third connecting plate 65, such that when the third connecting plate 65 moves in the second direction, the at least one first limiting block 66 may abut against one end of the piece-to-be-transferred in the second direction.
The fourth connecting plate 71 and the third connecting plate 65 are arranged in parallel to each other at an interval, such that when the third spiral transmission member 82 drives the first limiting block 66 on the third connecting plate 65 to move, the first limiting block 66 and the second limiting block 72 may cooperate to abut against two ends of the piece-to-be-transferred in the second direction, so as to clamp the two ends of the piece-to-be-transferred in the second direction.
It can be understood that a height of the first limiting block 66 and a height of the second limiting block 72 are greater than a height of the first step surface 363 and a height of the second step surface.
Specifically, the third connecting plate 65 and the fourth connecting plate 71 are further provided with a plurality of positioning recesses 351, the plurality of positioning recesses 351 on the third connecting plate 65 and the fourth connecting plate 71 are provided at intervals in the first direction, bottoms of the first limiting block 66 and the second limiting block 72 are provided with positioning columns 361, and the positioning columns 361 are inserted into the positioning recesses 351.
With reference to
When the positioning platform 20 is arranged on the supporting frame 11, the positioning pin 111 is inserted into the bearing guide sleeve 21 such that connection reliability between the positioning platform 20 and the supporting frame 11 can be improved. Moreover, a position of the positioning platform 20 relative to the supporting frame 11 is relatively fixed, which is conducive to improvement in stability of the piece-to-be-transferred in a transfer process.
With reference to
The handlebar 22 is configured to be held by an operator such that the operator can conveniently push the transfer device 100 to move as required.
With reference to
According to some embodiments of the present application, the positioning platform 20 is provided with a first graduated scale and a second graduated scale. The first graduated scale extends from one end of the positioning platform 20 to the other end in the first direction, and is configured to measure a moving distance of the first locking assembly 30. The second graduated scale extends from one end of the positioning platform 20 to the other end in the second direction, and is configured to measure a moving distance of the first limiting assembly 60.
