Description

A material dividing device for cylindrical battery production

Technical Field

The utility model relates to the field of battery production, in particular to a material dividing device for cylindrical battery production.

Background technique

Currently, metal-shell power batteries are mainly cylindrical batteries. The production process of cylindrical batteries often involves laser welding, which requires laser penetration welding of the tabs at both ends of the battery cell to the collector plate. As a development trend, large-sized cylindrical batteries, such as 4680 batteries, generally use a full-tab structure.

After the cylindrical battery is processed on the processing equipment, the battery is transported by a conveyor belt or a conveyor turntable. After the processing is completed, the battery needs to be tested. After the test is completed, the good and bad products are sorted, and the bad and good products are transported separately to avoid the mixing of good and bad products affecting the processing. The conveyor turntable and the arc baffle cooperate to form a conveying channel for conveying batteries. In the prior art, a swingable baffle is controlled by a cylinder or an electric cylinder to control the movement direction of the battery, and the baffle swings toward the conveying channel of the bad or good products. The piston rod of the cylinder needs to be connected to the baffle, and when the driving cylinder is installed on the arc baffle, the space on the side of the arc baffle away from the turntable will be occupied, affecting the installation of the equipment. When the cylinder or electric cylinder is installed above the baffle, the height of the battery will be limited. Therefore, a material dividing device that is combined with a conveying device to reduce the space occupancy rate is proposed to achieve pushing the battery to the conveying channel of the bad product or the conveying channel of the good product.

Preferably, the first driving mechanism applies force to the end of the peeling structure close to the axis of the rotating disk to rotate the end of the peeling structure to the first position. The first driving mechanism rotates the end of the peeling structure away from the axis of the rotating disk so that the peeling structure contacts and pushes out the battery in the workpiece slot.

Preferably, the second driving mechanism applies a force to the end of the peeling structure away from the axis of the rotating disk to rotate the end of the peeling structure to the second position.

At this time, the upper stripping block and the lower stripping block are located on the side of the workpiece groove close to the axis of the rotating shaft.

The support plate 2 is fixedly arranged directly above the turntable 1, and the first driving mechanism 4 and the second driving mechanism 5 are both arranged on the support plate 2.

The first driving mechanism 4 applies a force to the end of the peeling structure 3 close to the axis of the turntable 1 to rotate the end of the peeling structure 3 to the first position. The first driving mechanism 4 rotates the end of the peeling structure 3 away from the axis of the turntable 1, so that the peeling structure 3 contacts and pushes out the battery in the workpiece slot.

The second driving mechanism 5 applies a force to the end of the peeling structure 3 away from the axis of the turntable 1 to rotate the end of the peeling structure 3 to the second position. The second driving mechanism 5 rotates the end of the peeling structure 3 toward the axis of the turntable 1 to move the peeling structure 3 away from the workpiece slot and the battery in the workpiece slot.

The stripping structure 3 includes a rotating shaft, an upper stripping block, a lower stripping block and a protrusion. The rotating shaft can be rotatably set on the turntable 1. The two ends of the rotating shaft are respectively connected to one end of the upper stripping block and one end of the lower stripping block. The protrusion is set above the turntable 1.

As shown in Figures 1, 2 and 4, in one embodiment, the material dividing device for cylindrical battery production provided in the embodiment is different from the above-mentioned embodiment in that: the number of the material dividing mechanisms is two, the feed channel 6 and the first material discharging channel 7 surround one of the material dividing mechanisms, and the second material discharging channel 8 surrounds the other material dividing mechanism.

The working principle of the utility model is as follows: when the stripping structure 3 rotates with the turntable 1 to the position directly below the first driving mechanism 4, the telescopic device of the first driving mechanism 4 starts to drive the push block to move in the direction away from the telescopic device. The contact end at the lower end of the push block gradually approaches and contacts the protrusion at the upper end of the upper stripping block. The contact end at the lower end of the push block applies a force to the protrusion, causing the upper stripping block and the lower stripping block to rotate around the rotating shaft. At this time, the end of the upper stripping block and the lower stripping block away from the rotating shaft will move to the position of the workpiece slot. When the end of the upper stripping block and the lower stripping block away from the rotating shaft moves to the position of the workpiece slot, the upper stripping block and the lower stripping block will push out the battery in the workpiece slot, causing the battery in the workpiece slot to detach from the turntable 1 and enter the second discharge channel 8.

When the stripping structure 3 rotates with the turntable 1 to the right below the second driving mechanism 5, the push rod of the second driving mechanism 5 is fixed to one side of the protrusion through the bracket. Since the stripping block and the lower stripping block are pushed out by the first driving mechanism 4 at the previous station, the protrusion of the upper stripping block will contact the push rod. Since the push rod is fixed, the protrusion and the upper stripping block will be pushed by the push rod to move toward the axis of the turntable 1. This causes one end of the upper stripping block and the lower stripping block to move away from the position where the workpiece slot is located.

When the telescopic device of the first driving mechanism 4 is not started, the end of the upper stripping block and the lower stripping block away from the rotating shaft will remain stationary. At this time, the upper stripping block and the lower stripping block are located on the side of the workpiece groove close to the axis of the rotating shaft. The upper stripping block and the lower stripping block are away from the workpiece groove and the battery. The battery will rotate with the turntable 1 and finally enter the first discharge channel 7.

The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which should be considered as the scope of this specification.
