Abstract

This utility model discloses a multi-plate vibration device for preventing excessive weight in the stacking machine, including a robotic arm connected to the machine tool drive. A suction cup frame is connected and moves synchronously with the robotic arm on one side. The bottom of the suction cup frame has several suction cups for adsorbing battery electrodes. A vibrator bracket connected and cooperating with the robotic arm is located at the top of the suction cup frame. The vibrator bracket has a vibrator that drives the suction cup frame and suction cups to vibrate at its bottom, shaking off any other battery electrodes that are adsorbed by the suction cups. This ensures that the suction cups adsorb only one battery electrode at a time.

Description

Technical Field

[0001] This utility model relates to the field of battery processing, and in particular to a device for preventing multiple stacked wafers from vibrating during the feeding process of a stacking machine. Background Technology

[0002] In the battery production process, there is a lamination process, in which the positive and negative electrodes are separated and assembled into a cell using a separator of the appropriate specification. There are two ways to laminate the electrodes: one is manual lamination, and the other is machine lamination.

[0003] The automatic electrode stacking machine uses a negative pressure method to hold the electrode in place with a rubber gripping mechanism. Once the electrode is moved to a fixed position, the negative pressure in the gripping mechanism is turned off, and the electrode falls freely to the fixed position under gravity, completing the entire electrode picking and placing process. Although this achieves the task of gripping the electrode during automatic stacking, if the automatic stacking machine picks up two electrodes at once during the production process, and the two overlapping electrodes are treated as one electrode and wrapped into the cell, it will lead to defective products, rework in subsequent processes, or product scrap. To address this, a device to prevent vibration from multiple overlapping electrodes during the stacking machine's gripping process is proposed. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A vibratory device for preventing multiple battery electrodes from being picked up during a stacking machine includes a robotic arm connected to the machine tool drive. A suction cup frame that moves synchronously with the robotic arm is connected to one side of the robotic arm. Several suction cups for adsorbing battery electrodes are provided at the bottom of the suction cup frame. A vibrator bracket connected to the robotic arm is provided at the top of the suction cup frame. The vibrator bracket is equipped with a vibrator that drives the suction cup frame and suction cups to vibrate at its bottom and shakes off any other battery electrodes that are picked up by the suction cups, so that the suction cups pick up only one battery electrode at a time. Shock-absorbing springs are provided on the other side of the robotic arm to absorb and disperse the vibration force transmitted by the vibrator.

[0006] Preferably, the vibrator is a pneumatic vibration motor, and the vibrator is provided with an air inlet for air supply.

[0007] Preferably, the vibrator is an electric motor, and the vibrator is provided with a rotor shaft that rotates inside it, and a set of adjustable eccentric blocks are installed at each end of the rotor shaft, and the eccentric blocks rotate at high speed together with the rotor shaft, and the centrifugal force generated provides excitation force for the vibrator.

[0008] Preferably, the shock-absorbing spring and the vibrator are distributed opposite to each other, and the robotic arm is located between the shock-absorbing spring and the vibrator, and the shock-absorbing spring and the vibrator are in the same direction of movement with respect to the robotic arm.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the vibrator drives the vibrator bracket to vibrate the suction cup frame and suction cup at its bottom, and shakes off the other battery electrodes that are attached to the suction cup when they are adsorbed, so that the suction cup adsorbs only one battery electrode at a time. In addition, the other side of the robotic arm is provided with a shock-absorbing spring to absorb and disperse the vibration force transmitted by the vibrator, so that the robotic arm and suction cup frame remain stable when running, and the shock-absorbing spring ensures that the running accuracy of the robotic arm is not affected while absorbing the vibration force.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3In this embodiment of the present invention, a multi-piece vibration device for preventing excessive weight in the stacking machine includes a robotic arm 1 connected to the machine tool drive. A suction cup frame 2 is connected and moves synchronously with the robotic arm 1 on one side. The bottom of the suction cup frame 2 is provided with several suction cups 3 for adsorbing battery electrodes. A vibrator support 4, connected and cooperating with the robotic arm 1, is provided at the top of the suction cup frame 2. The vibrator support 4 is equipped with a vibrator 5 that drives the suction cup frame 2 and the suction cups 3 to vibrate at its bottom, and shakes off any remaining battery electrodes that are adsorbed by the suction cups 3, thus ensuring that the suction cups 3 adsorb only one battery electrode at a time. A shock-absorbing spring 6 is provided on the other side of the robotic arm 1 to absorb and disperse the vibration force transmitted by the vibrator 5, ensuring the stability of the robotic arm 1 and the suction cup frame 2 during operation. The shock-absorbing spring 6 absorbs the vibration force while ensuring that the operational accuracy of the robotic arm 1 is not affected.

[0018] The vibrator 5 is a pneumatic vibration motor, and it is equipped with an air inlet (not shown in the figure) for air supply. Controlling the opening of the inlet or outlet valve controls the flow rate of compressed air inside the vibrator 5, and adjusts its output power and rotational speed, thereby driving the suction cup frame 2 and suction cup 3 to vibrate. The vibrator 5 can employ known technologies, such as a TYF-18 worm gear pneumatic vibration motor. However, the specific selection and configuration of the vibrator 5 are not innovative aspects of this invention and can be implemented with reference to existing technologies; therefore, they will not be elaborated upon in the implementation details.

[0019] The vibrator 5 is an electric motor, and it is equipped with a rotor shaft (not shown in the figure) that rotates inside it. An adjustable eccentric block (not shown in the figure) is installed at each end of the rotor shaft. The eccentric blocks rotate at high speed together with the rotor shaft, and the resulting centrifugal force provides excitation force for the vibrator 5, thereby driving the vibrator support 4 and the suction cup frame 2 to vibrate. The vibrator 5 can employ known technologies, such as an XVM vibration motor. However, the specific selection and configuration of the vibrator 5 are not innovative aspects of this invention and can be implemented with reference to existing technologies; therefore, they will not be elaborated upon in the implementation details.

[0020] The shock-absorbing spring 6 and the vibrator 5 are distributed opposite to each other, and the robotic arm 1 is located between the shock-absorbing spring 6 and the vibrator 5. The shock-absorbing spring 6 and the vibrator 5 are in the same direction of movement with the robotic arm 1. The shock-absorbing spring 6 can be any one of spring steel, rubber and composite material. However, the specific selection and configuration of the shock-absorbing spring 6 is not the innovation of this utility model, and can be implemented with reference to the prior art. Therefore, it will not be described in detail in the implementation.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
