Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, and particularly relates to an equalizing mechanism. Background Art

[0002] In the formation stage of lithium batteries, generally, the lithium batteries are first placed between two adjacent partitions of a restraint tray, and then the partition is driven forward by a pressurizing mechanism of the restraint tray to reduce the distance between two adjacent partitions, so as to achieve the restraint and pressurization of the lithium batteries in the restraint tray. Then, the lithium batteries in the restraint tray that have been restrained and pressurized are subjected to formation treatment. Then, the partition is driven backward by the pressurizing mechanism of the restraint tray to increase the distance between two adjacent partitions, so as to achieve the release of the restraint on the lithium batteries in the restraint tray. Then, the restraint tray is placed on a conveyor line to convey the restraint tray to the disassembly and assembly tray station of the next process by the conveyor line. After the restraint tray reaches the disassembly and assembly tray station, the ejector rod group is first driven upward by the jacking drive mechanism of the conveyor line, so that the two ejector rods of the ejector rod group jack up the corresponding lithium battery upward, making the lithium battery located above the restraint tray. Then, the manipulator at the disassembly and assembly tray station clamps the lithium battery and transfers the clamped lithium battery to the production equipment of the next process.

[0003] After the restraint on the lithium batteries in the restraint tray is released, it is usually impossible to ensure that the lithium batteries in the restraint tray have been completely evenly distributed, so it is impossible to ensure that the distances between the lithium batteries are consistent. However, the distances between the ejector rod groups of the conveyor line are consistent, which results in a deviation between the positions of the lithium batteries and the positions of the two ejector rods of the corresponding ejector rod group. In this way, after the two ejector rods of the ejector rod group jack up the corresponding lithium battery upward, the lithium battery usually tilts or is skewed. When the manipulator clamps the lithium battery, it is easy to clamp it unstably or the lithium battery drops.

[0004] Therefore, there is an urgent need for an equalizing mechanism to solve the above technical problems. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an equalizing mechanism, which can evenly distribute the lithium batteries in the restraint tray, so as to ensure that the distances between the lithium batteries are consistent.

Then, the push-pull cylinder 41 is used to drive the push-pull fixing plate 50 to move forward, so as to drive the first hook and pull arm group, the second hook and pull arm group, and two transverse moving cylinders 71 to move forward, so that the first horizontal part 613 of the first hook and pull arm group, the second horizontal part 623 of the first hook and pull arm group, the first horizontal part 613 of the second hook and pull arm group, and the second horizontal part 623 of the second hook and pull arm group respectively pass through the corresponding tray notches 202 and are located inside the restraint tray 200. At this time, the two equalizing hooks 2011 on the first partition 201a of the first row of partitions of the restraint tray 200 are located between the first horizontal part 613 of the first hook body 612 of the first hook and pull arm group and the second horizontal part 623 of the second hook body 622 of the first hook and pull arm group, and the two equalizing hooks 2011 on the first partition 201b of the second row of partitions of the restraint tray 200 are located between the first horizontal part 613 of the first hook body 612 of the second hook and pull arm group and the second horizontal part 623 of the second hook body 622 of the second hook and pull arm group. Then, two transverse moving cylinders 71 are used to drive the first horizontal part 613 of the first hook and pull arm group and the second horizontal part 623 of the first hook and pull arm group to move towards each other, and the first horizontal part 613 of the second hook and pull arm group and the second horizontal part 623 of the second hook and pull arm group to move towards each other, so that the first horizontal part 613 of the first hook and pull arm group and the second horizontal part 623 of the first hook and pull arm group respectively cooperate and engage with the two equalizing hooks 2011 on the first partition 201a of the first row of partitions, and the first horizontal part 613 of the second hook and pull arm group and the second horizontal part 623 of the second hook and pull arm group respectively cooperate and engage with the two equalizing hooks 2011 on the first partition 201b of the second row of partitions, such as Figure 5 , Figure 6 , Figure 8As shown. Then, the push-pull cylinder 41 is driven to move the push-pull fixed plate 50 backward, thereby driving the first hook-pulling arm group, the second hook-pulling arm group, and the two transverse movement cylinders 71 to move backward. During the backward movement of the first hook-pulling arm group and the second hook-pulling arm group, the first partition 201a of the first row of partitions can be pulled backward by the first hook 61 and the second hook 62 of the first hook-pulling arm group. Since the adjacent partitions 201a of the first row of partitions are connected by a chain, the remaining partitions 201a of the first row of partitions can be pulled backward in sequence until the distance between adjacent partitions 201a is pulled to the maximum. In this way, the partitions 201a of the first row of partitions can be evenly spaced apart, so that the lithium batteries 300 of the first row of lithium batteries can be evenly spaced apart. Thus, the lithium batteries 300 in the first row in the restraint tray 200 are evenly distributed, and the distance between the lithium batteries 300 in the first row of lithium batteries is the same. The first partition 201b of the second row of partitions can be pulled backward by the first hook 61 and the second hook 62 of the second hook-pulling arm group. Since the adjacent partitions 201b of the second row of partitions are connected by a chain, the remaining partitions 201b of the second row of partitions can be pulled backward in sequence until the distance between adjacent partitions 201b is pulled to the maximum. Thus, the partitions 201b of the second row of partitions can be evenly spaced apart, so that the lithium batteries 300 of the second row of lithium batteries can be evenly spaced apart. Thus, the lithium batteries 300 in the second row in the restraint tray 200 are evenly distributed, and the distance between the lithium batteries 300 in the second row of lithium batteries is the same. Then, the two transverse movement cylinders 71 are driven to move the first transverse part 613 and the second transverse part 623 of the first hook-pulling arm group away from each other, and the first transverse part 613 and the second transverse part 623 of the second hook-pulling arm group away from each other, so that the first transverse part 613 and the second transverse part 623 of the first hook-pulling arm group are separated from the two equalizing hooks 2011 on the first partition 201a of the first row of partitions respectively, and the first transverse part 613 and the second transverse part 623 of the second hook-pulling arm group are separated from the two equalizing hooks 2011 on the first partition 201b of the second row of partitions respectively. Then, the push-pull cylinder 41 is driven to move the push-pull fixed plate 50 backward to the initial position, thereby driving the first hook-pulling arm group, the second hook-pulling arm group, and the two transverse movement cylinders 71 backward to the initial position, so that the first transverse part 613, the second transverse part 623 of the first hook-pulling arm group, the first transverse part 613, and the second transverse part 623 of the second hook-pulling arm group are respectively moved out of the restraint tray 200.Then, two lifting cylinders 21 are used to drive the planar fixing plate 30 to move upward to the initial position, thereby driving the push-pull cylinder 41, the push-pull fixing plate 50, the first hook-pull arm group, the second hook-pull arm group, and the two transverse movement cylinders 71 to move upward to the initial position.

[0046] Then, the two ejector rods 101 of the ejector rod group are driven to move upward by the jacking drive mechanism of the conveyor line 100. Thus, the corresponding lithium battery 300 can be jacked up by the two ejector rods 101, so that the lithium battery 300 is located above the restraint tray 200. The bottom end of the restraint tray 200 is provided with avoidance positions 203 corresponding to the two ejector rods 101 of each ejector rod group. During the upward movement of the two ejector rods 101, the two ejector rods 101 can be avoided through the avoidance positions 203. Then, the manipulator at the disassembly and assembly station can clamp the lithium battery 300 and transfer the clamped lithium battery 300 to the production equipment of the next process.

[0047] The equalization mechanism of the present utility model has a simple structure and low cost. By setting two side fixing plates 10 arranged opposite to each other left and right, a jacking drive assembly 20, a planar fixing plate 30, a push-pull drive assembly 40, a push-pull fixing plate 50, several hook-pull arm groups, and a transverse movement drive assembly, the lithium batteries 300 in the restraint tray 200 can be evenly distributed. Thus, the distance between the lithium batteries 300 can be ensured to be consistent, so that the positions of the lithium batteries 300 and the positions of the two ejector rods 101 of the corresponding ejector rod group will not deviate. In this way, after the corresponding lithium battery 300 is jacked up by the two ejector rods 101 of the ejector rod group, the lithium battery 300 will not be jacked off or skewed. When the manipulator clamps the lithium battery 300, the lithium battery 300 will not be clamped unstably or dropped.

[0048] The above is a specific description of the preferred embodiment of the present utility model. However, the present utility model is not limited to the described embodiment. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present utility model. These equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
