Description

Technical Field

[0001] This application relates to the technical field of battery liquid injection machines, and particularly to a residual liquid receiving mechanism and a battery liquid injection machine. Background Art

[0002] In the production process of lithium batteries, liquid injection is a crucial step, which specifically refers to evacuating the air in the formed lithium battery casing first and then filling it with electrolyte so that the electrolyte completely wraps the battery core. A liquid injection machine is required to complete the liquid injection process. After the liquid injection machine injects liquid, there is still some residual liquid in the liquid injection needle, which will affect the accuracy of the next liquid injection. Therefore, it is necessary to discharge the residual liquid from the liquid injection needle by applying positive pressure.

[0003] In the prior art, a liquid injection machine is equipped with densely distributed liquid injection needles to simultaneously inject liquid into multiple batteries. At the same time, a collection box for receiving the residual liquid in the liquid injection needles is also installed and arranged. Since the collection box will block the downward movement of the liquid injection needles to dock with the batteries, a relatively large horizontal space needs to be reserved on the liquid injection machine for the collection box to move horizontally to avoid the liquid injection needles that move downward to dock with the batteries. This will result in a large occupied space and a bulky structure of the liquid injection machine equipped with a residual liquid collection box, which is not conducive to cost reduction and efficiency improvement.

[0004] Therefore, it is necessary to study and improve the existing structure, and provide a residual liquid receiving mechanism and a battery liquid injection machine, in order to achieve a more practical value purpose. Summary of the Invention

[0005] The embodiments of this application provide a residual liquid receiving mechanism and a battery liquid injection machine to solve the problem that a relatively large horizontal space needs to be reserved on the liquid injection machine in the prior art for the collection box to move horizontally to avoid the liquid injection needles that move downward to dock with the batteries, resulting in a large occupied space and a bulky structure of the liquid injection machine.

[0022] Therefore, while the residual liquid receiving mechanism of the present application can collect the residual liquid discharged by the liquid injection needle by using the liquid receiving hole and the cavity above the residual liquid tray, it can also enable the liquid injection needle to dock with the battery to be injected by passing through the avoidance channel, and realize that the residual liquid tray can be avoided by moving it slightly horizontally.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0033] An embodiment of this application provides a residual liquid receiving mechanism and a battery liquid injection machine to solve the problem in the prior art that a large horizontal space needs to be reserved on the liquid injection machine for the collection box to move horizontally to avoid the liquid injection needle that moves downward to dock with the battery, resulting in a large occupied space and a bulky structure of the liquid injection machine.

[0034] See Figures 1 to 6 As shown, a first aspect of the embodiment of this application provides a residual liquid receiving mechanism, including:

[0035] A residual liquid tray 1, on which a cavity is provided, and a liquid receiving hole 2 communicated with the cavity;

[0036] An avoidance channel 3, which is arranged on the residual liquid tray 1 and penetrates the residual liquid tray 1 up and down, and the avoidance channel 3 is hermetically connected to the residual liquid tray 1.

[0037] In the residual liquid receiving mechanism of the embodiment of this application, the residual liquid tray 1 is provided with a liquid receiving hole 2 and an avoidance channel 3. The liquid receiving hole 2 is communicated with the cavity inside the residual liquid tray 1, and the residual liquid discharged from the liquid injection needle can be collected into the cavity through the liquid receiving hole 2.

[0038] The avoidance channel 3 penetrates the residual liquid tray 1 up and down. The liquid injection needle can pass through the avoidance channel 3 and then dock with the top liquid injection port of the battery to be liquid injected. In addition, the avoidance channel 3 is hermetically connected to the residual liquid tray 1, which can prevent the residual liquid in the cavity on the residual liquid tray 1 from leaking from the connection between the avoidance channel 3 and the residual liquid tray 1.

[0039] In this embodiment, the liquid injection needle docks with the battery to be liquid injected by passing through the avoidance channel 3, realizing that the residual liquid tray 1 can be avoided by moving it horizontally in a small range. This enables the liquid injection machine not to need to reserve a large horizontal space for the horizontal movement of the residual liquid tray 1. That is, the liquid injection machine equipped with the residual liquid receiving mechanism of this application can reduce the occupied space, and the compactness of its structure is greatly improved. The avoidance action time of the residual liquid tray 1 is shortened, the time for discharging residual liquid can be reduced, and thus the production efficiency can be improved to a certain extent and the production cost can be reduced.

[0040] Exemplarily, the residual liquid tray 1 is installed on the liquid injection machine and is located below the liquid injection needles arranged in an array. The residual liquid tray 1 is provided with liquid receiving holes 2 arranged in an array, and an avoidance channel 3 that penetrates the residual liquid tray 1 up and down is arranged between two adjacent liquid receiving holes 2 horizontally.

[0041] When it is necessary to collect the residual liquid, horizontally move the residual liquid tray 1 to align the liquid receiving holes 2 on the residual liquid tray 1 with the liquid injection needles, then move the residual liquid tray 1 upward so that the array-arranged liquid injection needles extend into the liquid receiving holes 2 one by one, and then apply positive pressure to the liquid injection needles to discharge the residual electrolyte inside.

[0042] After the residual liquid in the liquid injection needles is drained, move the residual liquid tray 1 downward. At this time, the liquid injection machine transports the tray with the batteries to be injected neatly arranged to the lower part of the residual liquid tray 1, and horizontally move the residual liquid tray 1 slightly, so that the avoidance channels 3 on the residual liquid tray 1 can be aligned with the liquid injection needles. Then move the residual liquid tray 1 and the tray upward, and the liquid injection needles pass through the avoidance channels 3 and then dock with the top liquid injection ports of the batteries to be injected, and start the liquid injection process.

[0043] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 6 As shown, the embodiment of the present application provides a residual liquid receiving mechanism. The residual liquid tray 1 of the residual liquid receiving mechanism includes a liquid receiving box 4 with an open top and a cover plate 5 for closing the liquid receiving box 4. The liquid receiving holes 2 are located on the cover plate 5 and are provided with a plurality of them at intervals along the length direction of the cover plate 5. The avoidance channels 3 are connected between the cover plate 5 and the liquid receiving box 4 and are located between two adjacent liquid receiving holes 2.

[0044] The residual liquid tray 1 of the embodiment of the present application includes a liquid receiving box 4 and a cover plate 5. The cover plate 5 is installed on the liquid receiving box 4 to close the opening of the liquid receiving box 4, which can slow down the volatilization and crystallization speed of the residual liquid in the liquid receiving box 4. A plurality of liquid receiving holes 2 are provided on the cover plate 5 and are distributed at intervals along the length direction of the cover plate 5, which can be correspondingly extended by the densely arranged liquid injection needles on the liquid injection machine.

[0045] At the same time, the avoidance channels 3 are connected between the cover plate 5 and the liquid receiving box 4 and are located between two adjacent liquid receiving holes 2, so that the liquid receiving box 4 and the cover plate 5 can be horizontally moved slightly to align the densely arranged liquid injection needles on the liquid injection machine with the avoidance channels 3, which is convenient for the liquid injection needles to dock with the batteries to be injected by passing through the avoidance channels 3.

[0046] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 6 As shown, the embodiment of the present application provides a residual liquid receiving mechanism. The number of the liquid receiving boxes 4 of the residual liquid receiving mechanism is multiple and are arranged side by side, and the top openings of the multiple liquid receiving boxes 4 are closed by the same cover plate 5.

[0047] In the embodiment of the present application, a plurality of liquid receiving boxes 4 are installed on the bottom surface of the cover plate 5 and are arranged side by side along the width direction of the cover plate 5. The cover plate 5 is made of a whole plate. Compared with splicing multiple plates, the installation efficiency can be improved. At the same time, setting a plurality of independent liquid receiving boxes 4 can reduce the manufacturing difficulty and the risk of liquid leakage.

[0048] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 6As shown in the figure, an embodiment of the present application provides a residual liquid receiving mechanism. The liquid receiving box 4 of the residual liquid receiving mechanism is detachably connected to the cover plate 5. The avoidance channel 3 includes a channel hole 6 provided on the cover plate 5 and a pipe 7 provided on the liquid receiving box 4 and hermetically docked with the channel hole 6.

[0049] In the embodiment of the present application, the liquid receiving box 4 and the cover plate 5 are detachably connected by bolts. The liquid receiving box 4 can be removed from the cover plate 5 for internal cleaning. To cooperate with the disassembly structure, a channel hole 6 is provided on the cover plate 5, and a pipe 7 is fixed on the liquid receiving box 4. When the liquid receiving box 4 and the cover plate 5 are installed together, the pipe 7 is hermetically docked with the channel hole 6 to form the avoidance channel 3. Exemplarily, a sealing ring can be embedded at the top end of the pipe 7 to axially press the bottom end of the channel hole 6 to improve the sealing performance.

[0050] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 6 As shown in the figure, an embodiment of the present application provides a residual liquid receiving mechanism. A circular rib 8 surrounding the liquid receiving hole 2 and the channel hole 6 is formed by protruding upward on the top surface of the cover plate 5 of the residual liquid receiving mechanism.

[0051] In the embodiment of the present application, the cover plate 5 has a circular rib 8 protruding upward. The liquid receiving hole 2 and the channel hole 6 are surrounded by the circular rib 8. The circular rib 8 can restrain the electrolyte dripping onto the top surface of the cover plate 5, so that the electrolyte on the top surface of the cover plate 5 can flow into the liquid receiving hole 2 and then be collected, preventing the residual liquid from flowing onto the residual liquid tray 1 and polluting the working environment.

[0052] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 6 As shown in the figure, an embodiment of the present application provides a residual liquid receiving mechanism. A circular flange 9 is formed by protruding upward at the top end of the channel hole 6 of the residual liquid receiving mechanism, and the height of the circular flange 9 is not less than the height of the circular rib 8.

[0053] In the embodiment of the present application, a circular flange 9 is formed by protruding upward at the top end of the channel hole 6. The circular flange 9 can prevent the electrolyte dripping onto the top surface of the cover plate 5 from flowing into the channel hole 6 and flowing out along the pipe 7, thereby preventing the residual liquid from flowing onto the residual liquid tray 1 and polluting the working environment.

[0054] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 6 As shown in the figure, an embodiment of the present application provides a residual liquid receiving mechanism. The inner cavity bottom wall of the liquid receiving box 4 of the residual liquid receiving mechanism is inclined, and a liquid discharge port 10 is provided at its lower end.

[0055] In the embodiment of the present application, the inner cavity bottom wall of the liquid receiving box 4 is inclined to form a one-sided inclined slope, which facilitates the residual liquid received in the liquid receiving box 4 to flow by gravity to the lower end of the residual liquid tray 1. At the same time, a liquid discharge port 10 is provided at the lower end, and the residual liquid can be centrally discharged through the liquid discharge port 10 after converging by gravity, improving the liquid discharge efficiency.

[0056] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 6 As shown, an embodiment of the present application provides a residual liquid receiving mechanism, which further includes a lifting module for driving the residual liquid tray 1 to lift and a lateral translation module for driving the residual liquid tray 1 to translate.

[0057] The lifting module of the embodiment of the present application can drive the residual liquid tray 1 to lift, and the lateral translation module can drive the residual liquid tray 1 to translate. Through the mutual cooperation of the lifting module and the lateral translation module, the injection needle can be inserted into the liquid receiving hole 2 or pass through the avoidance channel 3 to the battery to be injected.

[0058] Exemplarily, the residual liquid tray 1 is installed on the liquid injection machine and is located below the injection needles arranged in an array on the liquid injection machine. The residual liquid tray 1 is provided with liquid receiving holes 2 arranged in an array, and an avoidance channel 3 penetrating the residual liquid tray 1 up and down is arranged between two laterally adjacent liquid receiving holes 2.

[0059] When it is necessary to collect the residual liquid, the lateral translation module drives the residual liquid tray 1 to translate so that the liquid receiving holes 2 thereon are aligned with the injection needles, and then the lifting module is used to drive the residual liquid tray 1 to move up, so that the injection needles arranged in an array are inserted into the liquid receiving holes 2 one by one, and then a positive pressure is applied to the injection needles to discharge the residual electrolyte therein.

[0060] After the residual liquid in the injection needles is exhausted, the lifting module drives the residual liquid tray 1 to move down. At this time, the liquid injection machine transports the tray with the batteries to be injected neatly arranged to the lower part of the residual liquid tray 1. The lateral translation module is used to make the residual liquid tray 1 translate and align the avoidance channel 3 on the residual liquid tray 1 with the injection needles, and then the lifting module makes the residual liquid tray 1 move up. At the same time, the liquid injection machine lifts the tray, so that the injection needles pass through the avoidance channel 3 and then dock with the top injection ports of the batteries to be injected, and the injection process starts.

[0061] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 6 As shown, an embodiment of the present application provides a residual liquid receiving mechanism. The lifting module of the residual liquid receiving mechanism includes an inverted U-shaped frame 11 installed on the top surface of the residual liquid tray 1 and a lifting member 12 for jacking up the inverted U-shaped frame 11;

[0062] The lateral translation module includes a mounting plate 13 for mounting the lifting member 12 and a driving member for driving the mounting plate 13 to translate; the inverted U-shaped frame 11 penetrates through the mounting plate 13 and is slidably connected thereto, and a lateral translation guide post 14 is installed on the residual liquid tray 1.

[0063] On the top surface of the residual liquid tray 1 in the embodiment of the present application, an inverted U-shaped frame 11 is fixedly installed. The movable end of the lifting member 12 is connected to the middle section of the inverted U-shaped frame 11. The lifting member 12 can drive the inverted U-shaped frame 11 to lift, and then drive the residual liquid tray 1 to lift. The bottom end of the lifting member 12 is fixedly installed on the mounting plate 13. The driving member drives the mounting plate 13 to move horizontally, and then drives the residual liquid tray 1 indirectly connected to the mounting plate 13 to move horizontally.

[0064] The mounting plate 13 is arranged below the lifting member 12, which can create a space between the mounting plate 13 and the residual liquid tray 1, facilitating the arrangement of the liquid injection needle on the liquid injection machine between the mounting plate 13 and the residual liquid tray 1. Compared with the installation arrangement where the lifting member 12 is arranged below the mounting plate 13 and directly connected to the residual liquid tray 1, occupying the space for the arrangement of the liquid injection needle, in this embodiment, by adding the inverted U-shaped frame 11, the lifting member 12 can be arranged above the mounting plate 13, and the lifting member 12 will not be blocked by the dense liquid injection needles, thereby reducing the installation and disassembly difficulty of the lifting member 12.

[0065] Further, to improve the stability of the residual liquid tray 1 during lifting and horizontal movement, the inverted U-shaped frame 11 penetrates the mounting plate 13 and is slidably connected thereto, thereby playing a role of sliding guidance during lifting. At the same time, a horizontal movement guiding column 14 is installed on the top surface of the residual liquid tray 1, and the horizontal movement guiding column 14 can cooperate with the horizontally arranged strip-shaped sliding holes reserved on the liquid injection machine to play a role of horizontal movement guidance.

[0066] Exemplarily, two symmetrically distributed inverted U-shaped frames 11 are fixedly installed on the top surface of the residual liquid tray 1 in this embodiment through bolts. The inverted U-shaped frame 11 includes a top plate located above the residual liquid tray 1 and guide rods fixedly connected between the top plate and the residual liquid tray 1. A sliding sleeve cooperating with the guide rods is fixedly installed on the mounting plate 13. The lifting member 12 is a cylinder and is installed between the mounting plate 13 and the top plate.

[0067] The driving member (not shown in the figure) is a pneumatic slide table and is located between the liquid injection machine and the mounting plate 13. The horizontal movement guiding column 14 is a T-shaped guiding column, which penetrates the horizontally arranged strip-shaped sliding holes reserved on the liquid injection machine, and the small end is connected to the residual liquid tray 1 through screws. The T-shaped guiding column can slide horizontally along the strip-shaped sliding holes to play a role of horizontal movement guidance, and at the same time can slide longitudinally along the strip-shaped sliding holes without interfering with the lifting of the residual liquid tray 1.

[0068] See Figures 1 to 6 As shown, in the second aspect of the embodiment of the present application, a battery liquid injection machine is provided, including:

[0069] The residual liquid receiving mechanism of any of the above embodiments.

[0070] The battery liquid injection machine according to the embodiment of the present application is installed with the residual liquid receiving mechanism of any one of the above embodiments, which has the advantages of small equipment occupation space and good compactness of the mechanical structure. The liquid injection needle on the battery liquid injection machine can be connected to the battery to be injected by passing through the avoidance channel 3 on the residual liquid receiving mechanism. The avoidance action time of the residual liquid tray 1 on the residual liquid receiving mechanism is shortened, the time-consuming of discharging the residual liquid can be reduced, and the cost can be reduced and the efficiency can be improved to a certain extent.
