Description

Technical Field

[0001] This invention belongs to the field of lithium battery formation testing technology, and specifically relates to an integrated negative pressure restraint tray. Background Technology

[0002] With the significant development of the lithium battery industry, the requirements for the production effect and efficiency of lithium batteries are becoming increasingly stringent. Currently, the lithium battery production process requires the use of negative pressure suction nozzles to remove gases from inside the battery to prevent air bubbles in the electrolyte from affecting battery function. In conventional battery formation equipment, the negative pressure suction nozzle and the tray holding the batteries are independent mechanisms. Often, due to insufficient airtightness, the battery filling port is exposed, leading to electrolyte contamination. Therefore, the production process is usually carried out in a controlled environment at 45 degrees Celsius to prevent impurities from entering the electrolyte. Controlled environments require the extensive use of dehumidifiers to maintain air humidity, resulting in high energy consumption. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes an integrated negative pressure restraint tray that combines the battery tray and the negative pressure suction nozzle. The concept is as follows: by directly connecting the negative pressure suction nozzle to the battery's filling port, the airtightness during the negative pressure suction process is increased, significantly reducing the impact of ambient humidity on the battery formation process.

[0004] A negative pressure restraint integrated tray includes a battery tray assembly 1, a negative pressure collection cup assembly 2, and a buckle assembly 3. The battery tray assembly 1 includes a horizontal rectangular base plate 13. Vertical front end plates 11 and rear end plates 12 are respectively provided at both ends of the longitudinal direction of the base plate. The side of the front end plate 11 and the rear end plate 12 closest to each other is defined as the inner side, and the other side as the outer side. A support shaft 14 connects the transverse ends of the front end plate 11 and the rear end plate 12. A spacing adjustment plate 17 parallel to the front end plate passes through the support shaft 14 near the front end plate. A plurality of mounting components 18 are slidably passed through the support shaft 14 between the spacing adjustment plate 17 and the rear end plate 12 along the longitudinal direction. The mounting components 18 on the transverse sides of the support shaft 14 are arranged in pairs and flush with each other, and transverse separators 15 connect the pairs of mounting components 18. The longitudinally adjacent mounting components 18 are fitted together with a gap, so that the spacing between adjacent mounting components 18 is variable. The longitudinally adjacent partition components 15 form a battery slot for placing batteries; the partition component 15 closest to the spacing adjustment plate 17 is defined as the first partition component, and the partition component 15 closest to the rear end plate 12 is defined as the last partition component; the first partition component is connected to the spacing adjustment plate 17, and the last partition component is connected to the rear end plate 12; the outer sides of the front end plate 11 and the rear end plate 12 are provided with transverse buckle components 3, the buckle components include transverse buckle plates 31, the buckle plates 31 are provided with multiple equidistant protrusions, the protrusions have transverse connecting holes, the connecting holes are provided with transverse spring shafts 33, and the spring shafts 33 are provided with U-shaped buckles 32; the bottom of the negative pressure collection cup assembly 2 at both ends in the longitudinal direction is embedded in the buckles 32 of the front end plate and the rear end plate through protrusions 25, and is fixed by the spring shafts 33 passing through it; the negative pressure collection cup assembly 2 carries multiple collection cups 21 and is connected to the liquid injection port on the battery in the battery slot through the suction nozzle 23 at the bottom.

[0005] More specifically, a wedge plate 34 is provided at the end of the spring shaft 33 facing the buckle 32.

[0006] More specifically, the front end plate 11 is provided with a spacing adjustment component 16, which has a threaded screw structure in the front-back direction. Its nut is connected to the spacing adjustment plate 17 and can be rotated to make the spacing adjustment plate 17 slide longitudinally.

[0007] More specifically, the separator 15 is a plate-like structure that is thick at both ends and thin in the middle.

[0008] More specifically, one end of the card plate 31 on the front end plate 11 is connected to a limiting block 36 fixed on the front end plate 11 via a tray fixing pin 35, and one end of the card plate 31 on the rear end plate 12 is connected to a limiting block 36 fixed on the rear end plate 12 via a tray fixing pin 35.

[0009] More specifically, the negative pressure collection cup assembly includes a vertical rectangular metal frame 26. The two vertical sides of the metal frame 26 are connected by a horizontal manifold 22. Several vertical collection cups 21 are provided on the manifold 22. The suction nozzle 23 at the bottom of the collection cup 21 is located at the bottom of the metal frame 26 and is connected to the battery in the battery slot. The manifold 22 can buffer and transport the gas and electrolyte collected by the collection cups 21 from the battery.

[0010] More specifically, an automatic on / off valve 24 connected to the manifold 22 is provided on a vertical side of the metal frame 26, which can block the flow of gas and liquid to prevent the backflow of gas and electrolyte impurities.

[0011] The working process of this invention is as follows:

[0012] (1) The external mechanism removes the negative pressure collection cup assembly from the buckle, rotates the spacing adjustment assembly 16 to move the spacing adjustment plate to the front end, and straightens the spacing of the separator assembly to the maximum.

[0013] (2) Place the battery in the battery slot, rotate the spacing adjustment component 16 to make the separator component press the battery, and fix the negative pressure collection cup component back to the buckle through the protrusion, so that the suction nozzle is facing the liquid injection port of the battery to vent.

[0014] (3) After the venting is completed, the external mechanism will remove the negative pressure collection cup assembly from the buckle and push the battery out of the battery slot from below the separator assembly to remove the battery.

[0015] The advantages of this invention are: because the negative pressure nozzle is tightly connected to the restraint tray, the airtightness between it and the battery filling port is good, and the electrolyte can be kept uncontaminated without the need for external air dehumidification equipment. It can be used in uncontrolled environments at normal temperature, which greatly reduces the energy consumption of dehumidifiers and lowers the battery production cost. Attached Figure Description
