Abstract
Description
Technical Field
[0001] The utility model belongs to the field of battery manufacturing, and particularly relates to a cylindrical lithium battery turntable type-changing mechanism. Background Technique
[0002] During the lithium battery manufacturing process, it is necessary to continuously charge and discharge the lithium battery to detect and adjust the battery performance, and this process is also called battery formation. When testing the battery, a lifting cylinder is often used to connect the probe, and the probe is lowered to the contact position with the battery electrode to charge and discharge the battery. Lithium batteries with different heights often require external staff to manually adjust the positions of components such as the probe and the battery tray in the equipment according to the battery model to prevent the probe from descending too much and crushing the battery, and this process is also called battery type-changing.
[0003] In the prior art, the common practice of those skilled in the art is to use a limit post matching the battery model, so that when the lifting cylinder descends to contact the limit post, the probe just contacts the battery electrode. In large-scale production, using this method requires external staff to frequently replace the limit post according to the battery model, which is inconvenient to operate and has low work efficiency. Summary of the Invention
[0004] In view of the above problems, the utility model provides a cylindrical lithium battery turntable type-changing mechanism, which includes a mechanism bottom plate, and two rectangular turntable bottom plates are arranged on the mechanism bottom plate. Define the two pairs of sides of the turntable bottom plate as the front side and the rear side, and the other two pairs of sides as the left side and the right side; a rotating shaft sleeved with an angular contact ball bearing is arranged in the middle of the turntable bottom plate; a rack backing plate is arranged on the turntable bottom plate, and a chute extending left and right is arranged on the rack backing plate; a first push plate that can slide left and right is arranged in the chute, and a cylinder assembly is connected to the left side of the first push plate; a rack is connected to the rear side of the first push plate, a gear is sleeved on the rotating shaft, and the gear meshes with the rack; a ratchet wheel is arranged on the top of the gear, a ratchet groove is arranged on the edge of the ratchet wheel, and a type-changing turntable is connected to the top of the rotating shaft; eight circular limiting grooves are arranged on the type-changing turntable, the diameter of the top of the limiting groove is larger than that of the bottom, and a limiting post base is connected to the bottom of each limiting groove through an internal spring; different-height type-changing limit posts are respectively connected to the tops of the limiting post bases; a thin shaft is arranged at the bottom of the type-changing turntable, a torsion spring is arranged inside the thin shaft, the thin shaft is connected with a ratchet pawl, and the ratchet pawl touches the ratchet groove on the ratchet wheel; a spring plunger assembly connected to the turntable bottom plate is arranged on the left side of the ratchet pawl, and the spring plunger assembly contacts the type-changing turntable; a bottom post is arranged on the right side of the rotating shaft, and the bottom post is flush with a limiting groove up and down; four groove-shaped photoelectric sensors are arranged on the turntable bottom plate, and grooves allowing the type-changing turntable to pass through are arranged on the groove-shaped photoelectric sensors; the first push plates of the two turntable bottom plates are connected through a transmission belt; an external lifting cylinder flush with the bottom post up and down is arranged above the type-changing turntable.
[0005] More specifically, the conversion limiting post and the limiting post base are magnetically connected.
[0006] The working steps of the present utility model include:
[0007] 1. Place the battery tray filled with cylindrical lithium batteries of the same model into the battery tray storage location; an external probe assembly mechanically connected to an external lifting cylinder is provided at the top of the battery tray storage location;
[0008] 2. Input the model of the cylindrical lithium battery into the external controller, and give the number of the conversion limiting post corresponding to the cylindrical lithium battery, and then the controller gives an instruction;
[0009] 3. After the automatic conversion mechanism of the height limiting block of the cylindrical lithium battery receives the instruction, the cylinder assembly pushes the first push plate to slide left and right in the chute of the rack backing plate, and rotates the ratchet through the rack and gear; when the first push plate moves to the right, the ratchet rotates clockwise, and the ratchet pawl embedded in the ratchet groove pushes the conversion turntable to rotate clockwise; when the first push plate moves to the left, the ratchet rotates counterclockwise, and the ratchet pawl slides out of the ratchet groove, and the conversion turntable remains stationary due to the friction force in contact with the spring plunger assembly, and then the ratchet pawl resets under the action of the torsion spring; the cylinder assembly repeatedly pushes until the conversion limiting post corresponding to the cylindrical lithium battery rotates to directly above the bottom post, and the groove-shaped photoelectric induction detects the position of the conversion limiting post, and further detects whether the circumferential distance of the rotation of the conversion turntable is accurate;
[0010] 4. After the groove-shaped photoelectric detection is correct, the controller issues an instruction, and the external lifting cylinder starts to perform a downward movement, and drives the downward movement of the upper test probe component, driving the external probe assembly to descend synchronously; when the external lifting cylinder descends and touches the top of the conversion limiting post, the conversion limiting post is pressed down, the limiting post base touches the bottom post, the external lifting cylinder stops descending, and the external probe assembly also stops descending. At this time, the probe completes the conversion under the hard limit of the conversion limiting post and starts to charge and discharge the cylindrical lithium battery.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: few components, simple structure, can realize a completely automated battery conversion process, and has a wide range of applicable battery models. Description of the Drawings
