Description

Technical Field

[0001] The utility model relates to the technical field of liquid injection machines, in particular to a bell cover anti-dropping device for liquid injection machines. Background Art

[0002] In the production process of batteries, liquid injection is a crucial process, and the quality of liquid injection will directly affect the battery yield. Liquid injection refers to injecting electrolyte into the cavity through a certain process method, so that part of the electrolyte infiltrates into the interior of the battery cell, and the other part occupies the unfilled space. The more electrolyte infiltrates into the interior of the battery cell, the better the infiltration effect is relatively speaking. Under the existing technology, the electrolyte is infiltrated into the interior of the battery cell through a liquid injection machine. The shorter the liquid injection time of the liquid injection machine and the higher the efficiency, the better the process capability of the liquid injection machine. In order to improve the efficiency of liquid injection, semi-automatic or fully automatic liquid injection machines are now mostly used.

[0003] The existing automatic liquid injection machine generally adopts a vertical bell-shaped sealed liquid injection system, and its bell-shaped box body moves up and down through a lifting mechanism. By moving downward, the downward open sealed cover can be covered on the pressurized station of the bottom plate. Since the bell-shaped box is very high, it is easy to be unstable when it is lifted. When the parts become loose due to problems such as electrolyte corrosion, it is easy to cause safety problems. For example, the bell-shaped box falls and damages the battery or instrument to be injected, and even causes casualties in serious cases.

This patent uses a sling structure, which is only suitable for lighter bell covers, and the bell cover is prone to shaking and hitting other parts to cause secondary damage.

[0005] CN 2023102395758 discloses a battery injection breathing infiltration device, including a base, a sealed chamber, a chamber cover opening and closing mechanism, a chamber cover safety locking mechanism and a pipeline system. The sealed chamber includes a chamber cover, a chamber bottom, a sealing ring, a shelf, a snap and a snap driving mechanism, the chamber cover is fixed at the output end of the chamber cover opening and closing mechanism, and the chamber cover opening and closing mechanism can drive the chamber cover to rise and fall to open or close the sealed chamber. The pipeline system includes a compressed air pipe, a vacuum pipe, a nitrogen pipe, and an air pipe, which are connected to the sealed chamber, and the sealed chamber is continuously and alternately vacuumed and introduced with compressed air, so that the battery after injection in the sealed chamber is continuously and alternately vacuumed and introduced with compressed air, and the electrolyte is continuously and alternately infiltrated into the interior of the battery cell and then the bubbles are quickly extracted, which becomes a breathing infiltration, and finally nitrogen is introduced into the battery after injection. The battery injection breathing infiltration device can safely, quickly and thoroughly infiltrate the battery, and improve the production efficiency of battery injection.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] The utility model discloses a liquid injection machine bell cover anti-dropping device, which is used to solve the problem that the bell cover of the liquid injection machine drops due to failure of a lifting cylinder or a lifting support plate, thereby improving the use safety of the device.

[0025] like Figure 1 to Figure 2 As shown, the anti-falling device of the bell jar of the injection machine includes a blocking support plate 11 and a lifting support plate 3 arranged on the outer wall of the bell jar 1, the lifting support plate is connected to the lifting mechanism, and the lifting mechanism is vertically arranged on the outer side of the bell jar 1; a blocking column 10 driven to move horizontally is vertically arranged on the outer side of the bell jar, and when the blocking column moves to the blocking position, it cooperates with the blocking support plate 11 and abuts against the bottom surface of the blocking support plate 11 to prevent the bell jar 1 from falling.

[0026] The blocking support plate 11 is tightly fixed to the bell jar 1 and cannot move relative to it, and is used in conjunction with the blocking column. Preferably, the blocking support plate and the lifting support plate are welded to the outer surface of the bell jar. In some embodiments, the blocking column 10 is cylindrical or square.

[0027] In order to control the horizontal movement of the blocking column, a horizontal driving mechanism is provided on one side of the lower part of the blocking column, and the horizontal driving mechanism is connected to the blocking column. As a preferred embodiment, the horizontal driving mechanism includes a push-pull cylinder 9, and the push-pull cylinder is installed on a fixed base 8, and the fixed base 8 is located on the surface of the bottom plate of the equipment. Of course, other linear driving mechanisms are also possible, but not limited to this. The push-pull cylinder is controlled by an external computer, and the computer is not the same machine as the injection machine lifting control computer to prevent the same rise and fall due to program errors, which affects the realization of the anti-drop function of the present application. Among them, the push-pull cylinder 9 is tightly fixed to the side surface near the bottom of the blocking column 10 and cannot move relative to each other. The push-pull movement of the push-pull cylinder completes the change of whether the blocking column 10 can support the blocking support plate 11, that is, whether it is in a supporting state. In this way, by using the push-pull cylinder for control, the safe support and normal fall of the injection machine bell cover are completed through the horizontal linear movement of the blocking column.

[0028] In order to facilitate the movement of the blocking column and guide and limit the moving direction, the bottom of the blocking column is connected to a linear slide rail 7, and the blocking column moves linearly on the linear slide rail to change its position. The linear slide rail is located on the surface of the bottom plate of the equipment. The linear slide rail 7 is a standard model. The bottom of the column body of the blocking column is tightly fixed with a slide rail buckle. The column body and the slide rail buckle cannot move relative to each other. The blocking column as a whole can slide with the slide rail. The linear slide rail is matched with the slide rail buckle at the bottom of the blocking column.

[0029] In some embodiments, the lifting mechanism uses a lifting cylinder 4 installed on the surface of the equipment base plate 5. Of course, other linear lifting mechanisms can also be used, but are not limited to this.

[0030] In some embodiments, a guide rod 2 is vertically arranged on the outside of the bell jar to guide or direct the lifting movement of the bell jar. There may be more guide rods, but not limited to this. A guide hole that cooperates with the guide rod is provided on the outer wall of the bell jar. Preferably, there are two guide rods, which are symmetrically arranged on the outside of the bell jar.

[0032] When the liquid injection machine of the utility model is working, when the lifting cylinder pushes the bell jar 1 to rise to the top, the bell jar 1 is in a raised state. At this time, under the control of the push-pull cylinder, the blocking column moves from position B to position A to complete the support. When the bell jar 1 needs to land on the bottom 6 of the jar to complete the vacuuming of the liquid injection battery; at this time, under the control of the push-pull cylinder, the blocking column moves from position A to position B, cancels the support, and the lifting cylinder controls the bell jar 1 to slowly descend.

[0033] The utility model discloses a device for preventing the bell jar of an injection machine from falling off. The device has a blocking column which is driven and can move horizontally and is vertically arranged on the outer side of the bell jar. After the bell jar is raised, the blocking column moves to the blocking position and cooperates with the blocking support plate to abut against the bottom surface of the blocking support plate, thereby preventing the bell jar from falling off and the risk of falling off, thereby improving the safety of the equipment.

[0034] The utility model discloses a device for dropping the bell jar of a liquid injection machine, solves the problem that the bell jar of a liquid injection machine may fall due to failure of a lifting cylinder or a lifting support plate, reduces the potential safety hazard in the liquid injection section, is applicable to bell jars of various types of liquid injection machines, has a strong load-bearing capacity, and provides a stable protection process, the bell jar will not shake and collide with other parts to cause secondary damage, and is convenient to install and transfer.
