The camera 41 is fixedly arranged on the positioning support 42, the lens of the camera 41 faces the battery cell grabbing mechanism 2, the lens 44 is arranged between the lens of the camera 41 and the battery cell grabbing mechanism 2, the lens 44 is fixedly arranged on the lens support 43, the lens support 43 is fixedly arranged on the positioning support 42, the positioning support 42 is fixedly arranged on the framework 1, the camera 41 shoots a picture and then transmits the picture to the computer for analysis, the computer determines the grabbing position and then grabs the battery cell, in order to enable the picture shot by the camera 41 to be clearer, the grabbing precision is improved, and the grabbing precision is obviously improved by increasing the lens 44.
Because the whole skeleton 1 is large in size, the battery cores at a plurality of positions are difficult to be shot by a single camera 41, as a preferred embodiment, the positioning auxiliary mechanisms 4 comprise two, two positioning auxiliary mechanisms 4 are arranged on the same side of the skeleton 1, one positioning auxiliary mechanism 4 is close to the first anti-drop plate 311, the other positioning auxiliary mechanism 4 is close to the second anti-drop plate 312, the precision of the whole device is improved by using the method that the positioning auxiliary mechanisms 4 are arranged at the two ends of the same side of the skeleton 1, and the grabbing precision is obviously improved. According to the technical scheme, the more positioning auxiliary mechanisms 4 are arranged, the higher the grabbing precision is, and the embodiment only takes two positioning auxiliary mechanisms 4 as an example.
The following describes a method for using the feeding device for cell module packaging:
1. grabbing preparation:
in the use process, the position of the battery cell module is obtained by photographing through the camera 41, the feeding device of the battery cell module package is controlled to move towards the battery cell module through the mechanical arm connected with the hoisting frame 11 and reach a proper position, and firstly, the two anti-falling brackets 31 are controlled to move towards opposite directions and move to the farthest end through the control of the anti-degassing cylinder 32; secondly, starting the first lifting cylinder 314 and the second lifting cylinder 315 to lift the supporting rod 313; the motor 231 drives the gripper screw 232 to rotate, driving the main gripper plate 21 and the buffer gripper plate 22 to move in opposite directions until a suitable distance is reached, where the suitable distance is determined according to the cell module size, which distance needs to be larger than the cell module width direction size in order to be able to grip the cell module.
This process avoids the joist 313 from affecting the subsequent grabbing process. In order to obtain the positions of the anti-falling bracket 31, the main grabbing plate 21, the buffer grabbing plate 22 and the supporting rods 313, a plurality of position sensing switches are correspondingly arranged on the framework 1, the positions of the anti-falling bracket 31 and the supporting rods 313 are detected through the position sensing switches to control the opening, closing and moving directions of the anti-falling cylinder 32, the first lifting cylinder 314 and the second lifting cylinder 315, and the positions of the main grabbing plate 21 and the buffer grabbing plate 22 are used for controlling the forward and backward rotation and the start and stop of the motor 231.
2. The grabbing process comprises the following steps:
when the photograph taken by the camera 41 shows that the cell grabbing mechanism 2 reaches the proper position for grabbing the cell module, the motor 231 is started and drives the main grabbing plate 21 and the buffer grabbing plate 22 to move in the same direction, the mechanical arm lifts the cell module of the feeding device packaged by the cell module after clamping the cell module, at the moment, the anti-drop air cylinder 32 controls the two anti-drop brackets 31 to move in the same direction and reach the proper position, and meanwhile, the first lifting air cylinder 314 and the second lifting air cylinder 315 open the lifting supporting rod 313 to lift the cell module, so that the cell module is prevented from being separated by the cell grabbing mechanism 2 in the transferring process.
3. And (3) discharging:
after reaching the proper position, the first lifting cylinder 314 and the second lifting cylinder 315 are started to move the supporting rods 313 downwards, the anti-falling cylinder 32 controls the two anti-falling brackets 31 to move in opposite directions and completely separate from the battery cell module, and the first lifting cylinder 314 and the second lifting cylinder 31 are started again to lift the supporting rods 313; then through the arm, place the electric core module suitable position, through motor 231 drive snatch lead screw 232 rotation, drive main snatch board 21 and buffer snatch board 22 to opposite direction motion, until reaching suitable distance, electric core module breaks away from with electric core snatch mechanism 2 this moment, and the manipulator lifts the loading attachment of this electric core module packing and accomplishes once material loading.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
