According to an embodiment of the present invention, as shown in fig. 1 and 2, it can be seen that the battery case push-out mechanism 3 includes:
the two guide mounting plates 31 are arranged oppositely, and the two guide mounting plates 31 are parallel and arranged at intervals to define a yielding channel between the two guide mounting plates;
the two pushing plates 33 are arranged in the abdicating channel, and each pushing plate 33 is connected to the inner side of the corresponding guide mounting plate 31 in a sliding manner; and
two groups of pushing drivers 32, wherein the power output end of each group of pushing drivers 32 is in transmission connection with a corresponding pushing plate 33;
the pushing plate 33 is driven by the pushing driver 32 to push the battery case received in the abdicating channel outwards along the conveying direction of the battery case. Because its compact structure, reasonable in design, occupation space is little, during the in-service use, can arrange it in battery case's transfer path both sides, arrange like this and can obtain the advantage in at least two aspects: on one hand, the space on two sides of the conveying path of the storage battery shell is fully utilized, and the conveying of the storage battery is not interfered; on the other hand after electric core and the battery case phase separation in the battery, can release the vacant battery case in time from electric core release operation passageway to next battery carries out electric core/casing separation operation, has improved battery case's release efficiency.
Referring to fig. 1 and 2, a blocking plate 34 is rotatably connected to an inner side of each of the top pushing plates 33, and the blocking plate 34 is capable of rotating relative to the top pushing plates 33 to switch between a release state and a blocking state; when the dam plate 34 rotates in the conveying direction a of the battery case, the dam plate 34 is switched from the dam state to the release state; when the blocking plate 34 is rotated counter to the conveying direction a of the battery case, the blocking plate 34 switches from the clearance state to the blocking state. Because the blocking plates are rotatably connected to the inner sides of the pushing plates, and the blocking plates can rotate relative to the pushing plates to switch between a release state and a blocking state, on one hand, the blocking plates can avoid in the normal conveying process of the storage battery and prevent the blocking plates from interfering or blocking on the conveying path of the storage battery, and on the other hand, when the vacant storage battery shell needs to be pushed out, the blocking plates can act on the storage battery shell after being switched to the blocking state, the storage battery shell can be pushed out by the driving of the pushing driver 32, so that the force application area of the pushing plates is improved, meanwhile, the normal conveying of the storage battery cannot be interfered, and the pushing efficiency of the storage battery shell is improved.
Further, an abutting part is arranged between the blocking plate 34 and the push plate 33, and the abutting part acts on the blocking plate 34 so that the maximum opening angle of the blocking plate 34 is limited by the abutting part; when the blocker plate 34 is in the blocking condition, the blocker plate 34 extends at least approximately in a direction perpendicular to the ejector plate 33 toward the interior of the abduction channel.
In the embodiment shown in fig. 3, the abutting member is a semi-closed mounting groove 3321 formed at an end portion of the pushing plate 33, the end portion of the pushing plate 33 is opened to form a mounting groove notch, an abutting wall opposite to the mounting groove notch is formed in the mounting groove 3321, the blocking plate 34 is inserted into the mounting groove 3321 and rotatably coupled to the pushing plate 33, when the blocking plate 34 is in the blocking state, the insertion portion of the blocking plate 34 abuts against the abutting wall, and an opening angle of the blocking plate 34 is limited by the abutting wall such that the blocking plate 34 extends at least approximately in a direction perpendicular to the pushing plate 33 toward the inside of the escape passage.
Further, when the blocking plate 34 is in the blocking state, the distance between the two blocking plates 34 is smaller than the width dimension of the battery case. Thereby allowing the dam plate 34 to interfere with the battery case and thus enabling interaction between the dam plate 34 and the battery case.
Further, when the dam plate 34 is in the released state, the extending direction of the dam plate 34 is substantially parallel to the extending direction of the ejector plate 33. So that the dam plate 34 does not interfere with the normal transfer of the secondary batteries.
Further, when the blocking plate 34 is in the released state, the distance between the two blocking plates 34 is greater than or equal to the width dimension of the battery case.
Referring again to fig. 1, an arresting return member 341 is elastically coupled between the arresting plate 34 and the push plate 33, and the arresting return member 341 acts on the arresting plate 34 to return the arresting plate 34 to the arresting state from the released state by rotating the arresting plate 34 against the conveying direction of the battery case. The reset part 341 is configured to reset the blocking plate 34 from the released state to the blocking state without an additional driving device, thereby simplifying the structure and further reducing the overall cost.
When the battery core in the storage battery is pushed out, the pushing driver 32 drives the pushing plate 33 to reversely slide towards the storage battery conveying direction a, when the blocking plate 34 is in contact with the storage battery shell in the abdicating channel, the blocking plate 34 rotates along the conveying direction a of the storage battery shell, so that the blocking plate 34 is switched from the blocking state to the releasing state, and at the moment, the blocking plate 34 does not apply any pushing force in any direction to the storage battery shell; when the blocking plate 34 passes over the battery case and is separated from the battery case, the blocking plate 34 rotates against the conveying direction a of the battery case under the action of the blocking reset part 341, the blocking plate 34 is switched from the release state to the blocking state, and at this time, if the pushing driver 32 drives the pushing plate 33 to slide along the conveying direction a of the battery, the battery case in the yielding channel can be pushed out through the blocking plate 34.
In the embodiment shown in fig. 1, at least two pushing guide rails 311 arranged in parallel along the vertical direction are fixedly connected to the inner side of each guide mounting plate 31, the extending direction of the pushing guide rail 311 is consistent with the pushing direction of the pushing plate 33, and each pushing plate 33 is slidably connected to the pushing guide rail 311 on the corresponding guide mounting plate 31. The arrangement of the plurality of ejector rails 311 may enable the ejector plate 33 to be held in a vertical plane on the one hand, and may improve the sliding stability of the ejector plate 33 on the other hand.
Further, the ejector 33 includes:
the pushing driving section 331 is in transmission connection with the power output end of the pushing driver 32; and
a push transmission section 332 integrally coupled to the push driving section 331;
wherein the size of the ejection transmission section 332 in the vertical direction is substantially smaller than the size of the ejection driving section 331 in the vertical direction. By adopting the structure, on one hand, the material consumption of the pushing transmission section 332 can be reduced on the premise of not reducing the structural strength of the pushing transmission section 332, so that the cost is reduced, and on the other hand, the sufficient structural strength can still be ensured for the pushing driving section 331 for transmitting the driving force of the pushing driver 32.
Further, the guide mounting plate 31 is provided with a plurality of lightening holes 312. The lightening holes 312 can reduce the weight and material consumption of the guide mounting plate 31, and further reduce the cost.
The number of apparatuses and the scale of the process described herein are intended to simplify the description of the present invention. Applications, modifications and variations of the present invention will be apparent to those skilled in the art.
