Description

Technical Field

[0001] This utility model relates to the field of high-temperature negative pressure formation technology, and in particular to an integrated tray needle bed suitable for negative pressure formation equipment. Background Technology

[0002] After a lithium battery is manufactured, it needs to be activated by charging and discharging in a certain way. Therefore, formation testing equipment is needed to improve the charging and discharging performance, self-discharge performance and energy storage performance of the lithium battery.

[0003] Traditional testing equipment uses a fixed negative pressure cup assembly that cannot move with the tray. This leaves the lithium battery's filling port open after the pin is removed, allowing fine dust from the production workshop to fall in and affect the battery's quality. Therefore, maintaining a clean production environment requires significant investment of money and resources. However, with the continuous development and expansion of the lithium battery industry, production demands are increasing, and production lines are constantly being added. This necessitates continuous investment in production environment management and control, leading to a need for companies to continuously add personnel for management and control, thus increasing production costs.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide an integrated tray needle bed suitable for negative pressure formation equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated tray needle bed suitable for negative pressure formation equipment includes a base plate, a top plate, and a support column located between the two for supporting and fixing. A movable plate and a lifting drive cylinder are provided between the top plate and the base plate. The lifting drive cylinder is fixedly installed on the top plate and extends a movable telescopic rod downward. One end of the movable telescopic rod is connected and fixed to the movable plate and controls its up and down movement.

[0008] Between the top plate and the movable plate, there is also a restraint tray, a negative pressure mechanism, and a probe mechanism. The restraint tray is moved and placed on the movable plate for the lithium battery to be placed inside. The negative pressure mechanism is located above the restraint tray and covers the lithium battery. The probe mechanism is fixedly installed on the lower end face of the top plate and extends downward. The lifting drive cylinder drives the movable plate to move up and down, and lifts the restraint tray upward through the movable plate, so that the lithium battery placed inside it moves upward and closes to the probe mechanism on the top plate.

[0009] As a preferred embodiment, the edge of the movable plate is provided with a through hole for the support column to pass through. A linear bearing fitted onto the support column is provided in the through hole.

A gas pipe is provided between the negative pressure cup and the gas manifold, connecting the two. The lower end of the negative pressure cup is provided with a suction nozzle for adsorbing onto the lithium battery. The suction nozzle of the negative pressure cup adsorbs onto the lithium battery and is vacuum-treated by the gas manifold, thereby placing the opening of the lithium battery in a negative pressure adsorption state.

[0014] As a preferred embodiment, the number of negative pressure cups is set to a plurality of them, and the plurality of negative pressure cups are arranged in an array at intervals on the negative pressure frame and located at both ends thereon. The plurality of negative pressure cups are connected to the gas manifold through a gas pipe.

The scale is fixed to the side end of the guide rail and located above the positive probe assembly and the negative probe. The positive probe assembly and the negative probe assembly slide and unfold along the extension direction of the guide rail, maintaining a certain distance between them, so that the negative pressure frame can move upward and extend between them.

[0017] As a preferred embodiment, the number of positive probe components and negative probe components is at least two sets, and the two sets of positive probe components and negative probe components are arrayed on the top plate. A connecting plate is provided between the arrayed positive probe components or negative probe components. The two ends of the connecting plate are respectively connected and fixed to the slide of the positive probe component or negative probe component, so that when the user adjusts the positive probe component or negative probe component at one end, the positive probe component or negative probe component at the other end can move accordingly, thereby maintaining a stable interval between the positive probe component and the negative probe component.

[0018] As a preferred embodiment, the negative pressure base frame is equipped with a gas control valve, one end of which is connected to a gas manifold and the other end is connected to a vacuum device;

[0019] The top plate is also provided with an automatic power supply component, and the restraint tray is provided with an automatic power-taking component opposite to the automatic power supply component. The automatic power-taking component is used to supply power to the restraint tray.

[0021] This utility model has a simple structure and is convenient and quick to use. By detachably installing and fixing the negative pressure mechanism to the restraint tray, the negative pressure mechanism can be quickly assembled and locked onto the restraint tray. This allows the lithium batteries inside the tray to be adsorbed and isolated by the suction nozzle of the negative pressure cup, preventing fine dust from the production environment from falling into the lithium batteries during the movement of the restraint tray. The restraint tray is quickly transferred to the support feet of the base plate by a palletizer. Through the quick positioning installation of the positioning shaft and positioning holes, the restraint tray can be quickly and accurately placed on the base plate. The lifting drive cylinder controls the movable plate to lift the restraint tray upward, so that the internal lithium battery tabs can contact the positive and negative probe modules above, thereby completing the test.

[0022] This equipment effectively prevents dust contamination of lithium batteries by arranging the restraint tray and negative pressure mechanism together, reduces the cleanliness requirements of the space, reduces the investment costs of enterprises, and also reduces the need for additional personnel, thus realizing an automated production process.
