Description
Technical Field
[0001] This utility model relates to the field of high-temperature negative pressure formation equipment technology, and in particular to a needle bed suitable for an integrated negative pressure formation tray. Background Technology
[0002] During the production process, lithium batteries require negative pressure formation treatment. The main purpose of this treatment is to extract harmful gases from inside the lithium battery.
[0003] Currently, commonly used chemical bed probe modules cannot be moved or have their pitch changed during production. Furthermore, when combined with a restraint tray, the overall height of the bed probe device becomes quite high, resulting in a large overall space occupation. This makes it difficult to effectively utilize space, leading to higher production costs for enterprises and hindering subsequent maintenance and repair.
[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 a needle bed suitable for an integrated negative pressure forming tray.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The movable layer is located between the base and the top plate and moves up and down along the axial direction through the support column. A first driving mechanism is provided on the lower end face of the top plate. One end of the first driving mechanism is fixedly connected to the movable layer and controls its movement. A probe module displacement mechanism is also provided on the lower end face of the top plate and is located inside the first driving mechanism. The probe module displacement mechanism includes a positive probe module, a negative probe module, and an adjustment driving module. The adjustment driving module is located between the positive probe module and the negative probe module. The adjustment driving module has an adjustment cylinder for automatically adjusting the distance between the positive probe module and the negative probe module.

[0008] As a preferred embodiment, the adjustment drive module further includes a guide rail, a slider, and a manual adjustment screw. The guide rail is respectively located at the left and right ends of the top plate. One end of the slider is slidably mounted on the guide rail, and the other end is used to mount and fix the upper end of the positive probe module or the negative probe module. The adjustment cylinder is fixedly installed at the middle position of the top plate. The adjustment cylinder extends an inward movable rod and is connected and fixed to the outer end of the positive probe module or the negative probe module. The positive probe module or the negative probe module moves under the control of the adjustment cylinder, allowing it to slide along the extension direction of the guide rail, thereby changing the interval distance between the positive probe module and the negative probe module.
[0009] The manual adjustment screw is located on the side of the positive probe module or the negative probe module, allowing manual adjustment of the distance between the positive probe module and the negative probe module. The adjustment cylinder controls the movement of the positive probe module or the negative probe module, and also drives the distance between the other positive probe module or the negative probe module.

The limit sensor and the reset sensor are fixed to the lower surface of the top plate, with the reset sensor located behind the contact block and the limit sensor located in front of the contact plate. When the sensing plate moves forward with the positive or negative probe module, its upper contact block contacts the limit sensor, thus triggering a forward movement limit alarm. When the sensing plate moves backward with the positive or negative probe module, its upper contact block contacts the reset sensor, thus triggering a backward movement reset alarm.
[0011] As a preferred embodiment, the negative probe module is further provided with downwardly extending probe heads, the number of which is set to several, and the array of several probe heads is distributed on the negative probe module.
[0012] As a preferred embodiment, the number of probe module displacement mechanisms is set to one or more, and the one or more probe module displacement mechanisms are arranged side by side with a gap between them. The adjusting cylinder is located at the outer edge of the top plate and is used to control the positive probe module or negative probe module located on the outer side.
[0013] As a preferred embodiment, the upper inner surface of the base is also provided with an upwardly protruding support foot, and a positioning post is provided on one side of the upper end of the support foot. The number of support feet and positioning posts is set to a plurality of them, and the plurality of support feet and positioning posts are arranged in an array at the upper inner end of the base and pass through the movable layer.
[0014] As a preferred embodiment, the device also includes a restraint tray, which is placed on the support foot. The lower end face of the restraint tray is provided with a positioning hole corresponding to the position of the positioning post. The restraint tray is moved and placed above the support foot, so that the positioning hole can be quickly aligned with the positioning post, thereby forming a hole fit between the two for rapid positioning and restraint.
[0015] As a preferred embodiment, the movable layer is further provided with an upwardly protruding limiting plate. The limiting plate is fixedly installed on the upper surface of the movable layer and moves up and down with it.

The size between the limiting plates at the left and right ends is the same as the diameter of the restraint tray.
[0016] As a preferred embodiment, the restraint tray contains several lithium batteries placed inside, and a negative pressure module is also provided at the upper end of the restraint tray. The negative pressure module is located between the positive probe module and the negative probe module. The first driving mechanism drives the movable layer to move upward and lifts the restraint tray upward, so that the lithium batteries respectively contact the corresponding positive probe module and negative probe module.
[0017] As a preferred embodiment, the outer end of the negative pressure module is provided with an automatic air intake component, and the lower end face of the top plate is provided with an automatic air supply cylinder corresponding to the position of the automatic air intake component. The negative pressure module moves upward to a predetermined position, so that the automatic air intake component and the automatic air supply cylinder are connected and fixed together to form a communication state for air supply.
[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:
[0019] This utility model features a simple structure, reasonable layout, and convenient and quick operation. By setting an adjusting cylinder on the top plate, it automatically changes the moving positions of the positive and negative probe modules, allowing them to move and avoid the negative pressure module. It can also control the positive or negative probe module to reset. Furthermore, the first driving mechanism drives the movable layer to move upward, thereby lifting the restraint tray upward and allowing the lithium battery to approach the positive and negative probe modules, thus completing the processing. This effectively reduces the overall height of the equipment, resulting in a reasonable internal layout, efficient use of space, reduced factory space requirements, and lower production costs for enterprises.
[0020] By setting the height of the entire equipment at 1.1 meters, the overall height can be reasonably arranged with other equipment, improving the utilization and occupancy rate of the factory, and also saving on equipment design costs, material costs, and processing costs, effectively reducing the company's costs.
