[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is based on Chinese patent application number 202420148475.4, application date January 22, 2024, and invention name “A battery injection system and transfer device thereof”, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby incorporated into this disclosure as a reference. Technical Field

[0003] The present disclosure relates to the technical field of battery production equipment, and in particular to a battery liquid injection system and a transfer device thereof. Background Art

[0004] This section is intended to provide a background or context for the embodiments of the present disclosure. No admission is made that the description herein is prior art by virtue of its inclusion in this section.

[0005] Existing liquid injection systems typically include a conveyor mechanism, a supporting mechanism, and a liquid injection mechanism. The supporting mechanism is located on the conveyor mechanism and is used to carry batteries. The conveyor mechanism can drive the supporting mechanism to transport the battery to different workstations in sequence. In related technologies, because the supporting mechanism is fixed to the conveyor mechanism, when the supporting mechanism moves to the loading and unloading station, the loading and unloading robot will interfere with the conveyor mechanism when loading and unloading the supporting mechanism, making loading and unloading inconvenient.

[0006] Utility Model Content

[0007] In view of this, the embodiments of the present disclosure hope to provide a battery injection system and a transfer device thereof, which can facilitate loading and unloading of materials while being conducive to maintenance of the injection system.

[0008] To achieve the above objectives, a first aspect of an embodiment of the present disclosure provides a battery injection system, comprising:

[0009] A rotatable turntable, wherein a plurality of mounting areas are provided on the turntable, and the mounting areas are spaced apart along the circumference of the turntable;

[0010] A fixture for carrying batteries, wherein one of the turntable and the fixture is provided with a first insertion slot, and the other is provided with a first plug-in member, the first plug-in member and the first insertion slot are plugged and matched along the height direction of the fixture to detachably mount the fixture to the mounting area, and the fixture can move upward and detach from the turntable under the action of an external force, and the turntable rotates to drive the fixture to rotate along the circumference of the turntable;

[0011] The transfer device includes a base and a first lifting mechanism arranged on the base, wherein the first lifting mechanism is used to drive the clamp to move along the height direction of the clamp so that the clamp can be assembled to the turntable or detached from the turntable.

[0012] The embodiment of the present disclosure provides a battery injection system, which includes a rotatable turntable, a clamp for carrying batteries, and a transfer device. By detachably mounting the clamp to the mounting area of ​​the turntable, the battery can be loaded and unloaded by transferring the clamp to the outside of the turntable, which is beneficial to the loading and unloading of the battery (i.e., it is convenient to place the battery in or out of the receiving slot of the clamp). To a certain extent, the interference between the manipulator and the turntable when loading and unloading the battery can be avoided. In addition, since the clamp and the turntable are detachably connected, it is also beneficial to maintain the clamp, thereby facilitating the maintenance of the injection system, and making it convenient to maintain and change the clamp. Furthermore, the clamp and the turntable are plugged into and matched with the first plug-in slot through the first plug-in connector. Whether for assembly or disassembly, only the clamp needs to move linearly in the plug-in direction or the opposite direction of the plug-in direction. The movement mode is single, and the clamp and the turntable can be quickly assembled and disassembled. The operation is convenient, the assembly efficiency of the clamp is improved, the assembly cost is reduced, and the machine is also convenient to operate. Moreover, the turntable can be simplified, the flexibility of the injection system can be improved, and rapid mold change is convenient. The fixtures can be maintained in turn, reducing labor intensity.

[0013] In some embodiments, the first lifting mechanism is supported on the bottom of the clamp.

[0014] By supporting the first lifting mechanism at the bottom of the fixture, the coordination between the first lifting mechanism and the fixture is improved, the space required for the first lifting mechanism to move is reduced, and the compactness of the injection system is improved. For example, the first lifting mechanism does not need to be wrapped around or supported by the side wall of the fixture, which can reduce the space required on the side of the fixture.

[0015] In some embodiments, one of the first lifting mechanism and the clamp is provided with a second plug-in slot, and the other is provided with a second plug-in component, and the second plug-in component is plug-fitted with the second plug-in slot along the height direction of the clamp.

[0016] In this embodiment, during assembly, the first lifting mechanism is inserted into the clamp from bottom to top. Thereafter, the clamp's own weight helps maintain the clamp in the plugged-in position. Furthermore, as the first lifting mechanism drives the clamp in the height direction, the clamp's own weight helps maintain the clamp in the plugged-in position. Therefore, even if the clamp is not limited in its upward movement, the clamp can be relatively reliably maintained in the plugged-in position. Furthermore, the clamp's weight does not generate a horizontal force component on the clamp, which helps increase the clamp's reliability. The cooperation between the second connector and the second insertion slot can limit the clamp in the horizontal direction.

[0017] In some embodiments, the turntable includes a supporting member for supporting the clamp, and the number of the first lifting mechanisms is two. The two first lifting mechanisms are arranged at intervals and abut against the clamp to avoid the supporting member.

[0018] There are two first jacking mechanisms, which are arranged at intervals and abut against the clamp to avoid the carrier. For example, the two first jacking mechanisms abut against the bottom of the clamp respectively, which improves the cooperation stability between the first jacking mechanism and the clamp. During assembly, the first jacking mechanism can first move the clamp to the top of the carrier, and then move the clamp from top to bottom so that the clamp and the base are plugged into and matched with the first connector through the first plug-in slot. At this time, the carrier is located between the two first jacking mechanisms, that is, the gap between the two first jacking mechanisms is used to avoid the carrier, or, in other words, the gap between the carriers between adjacent installation areas is used to avoid the first jacking mechanism.

[0019] In some embodiments, the transfer device further includes a drive module and a battery loading and unloading station, wherein the drive module is used to drive the first lifting mechanism to move along a first direction, and the battery loading and unloading station is arranged on the side of the transfer device away from the turntable along the first direction, and the first lifting mechanism can move the clamp away from the battery loading and unloading station or transfer the clamp to the battery loading and unloading station, wherein the first direction is perpendicular to the height direction.

[0020] In this way, the first lifting mechanism can be used to drive the clamp to move along the height direction of the clamp to disengage the clamp from the turntable, and then the driving module can be used to drive the clamp to move along the first direction to move the clamp to the battery loading and unloading station. The first lifting mechanism drives the clamp to move along the height direction of the clamp to assemble the clamp to the battery loading and unloading station. That is to say, the transfer device can transfer the clamp to the battery loading and unloading station outside the turntable and then load and unload the battery, which is beneficial to the loading and unloading of the battery (i.e., it is convenient to place the battery in or out of the clamp's receiving slot), and to a certain extent, it can avoid interference between the manipulator and the turntable when loading and unloading the battery. After the clamp is reloaded with the battery, the first lifting mechanism drives the clamp to move along the height direction of the clamp to disengage the clamp from the battery loading and unloading station, and then the driving module can be used to drive the clamp to move along the first direction to move the clamp to the turntable. The first lifting mechanism drives the clamp to move along the height direction of the clamp to assemble the clamp to the turntable.

[0021] In some embodiments, one of the battery loading and unloading station and the clamp is provided with a third plug-in slot, and the other is provided with a third connector, and the third connector is plugged into and fitted with the third plug-in slot along the height direction of the clamp.

[0022] In this embodiment, during assembly, the clamp is inserted from top to bottom onto the battery loading and unloading station. Thereafter, the clamp's own weight helps maintain the clamp in the inserted position. Furthermore, when the battery loading and unloading station rotates the clamp, the clamp is substantially immune to upward forces. Therefore, even without limiting the clamp's upward movement, the clamp can still be reliably maintained in the inserted position. Furthermore, the clamp's weight does not generate a horizontal force component, which helps enhance the clamp's reliability.

[0023] In some embodiments, the first plug-in slot and the third plug-in slot are provided on the clamp and are the same plug-in slot on the clamp.

[0024] In this embodiment, the fixture is provided with the same plug-in slot to cooperate with the battery loading and unloading station or the turntable respectively. That is to say, the battery loading and unloading station and the turntable can share the plug-in slot on the fixture, so that the fixture can reduce the setting of the plug-in slot, which is beneficial to improving the processing efficiency of the fixture and improving the structural strength of the fixture.

[0025] In some embodiments, the transfer device includes a second lifting mechanism disposed below the battery loading and unloading station, and the second lifting mechanism is used to eject the battery in the fixture located on the battery loading and unloading station.

[0026] By setting up a second lifting mechanism, it is used to eject the battery in the clamp located on the battery loading and unloading station, that is, the second lifting mechanism is used to eject the battery in the accommodating groove, which is beneficial for the robot to clamp the battery, thus facilitating the unloading of the battery.

[0027] In some embodiments, a first avoidance groove is provided at the bottom of the clamp, and a second avoidance groove corresponding to the first avoidance groove is provided at the battery loading and unloading station. The ejector rod of the second lifting mechanism moves along the height direction of the clamp, and extends into the clamp through the second avoidance groove and the first avoidance groove in turn, and ejects the battery in the clamp.

[0028] By opening a first avoidance groove at the bottom of the clamp, a second avoidance groove corresponding to the first avoidance groove is provided at the battery loading and unloading station, so that the ejector rod of the second lifting mechanism extends into the clamp through the second avoidance groove and the first avoidance groove in sequence, and ejects the battery in the clamp. The structure is simple and reliable.

[0029] In some embodiments, the first avoidance grooves extend along the first direction, and there are multiple first avoidance grooves, each of which is arranged along the second direction, and the first direction and the second direction intersect.

[0030] By setting the number of the first avoidance grooves to be multiple and the first avoidance grooves are arranged along the second direction, multiple batteries can be ejected simultaneously, which is beneficial to improving the battery unloading efficiency.

[0031] In some embodiments, the first avoidance groove extends along the first direction, the number of the push rods in each first avoidance groove is multiple, and the push rods in the same first avoidance groove are spaced apart along the first direction.

[0032] By setting the number of ejector pins to be multiple, each ejector pin is spaced apart along the first direction, that is, multiple ejector pins can cooperate with the battery in the accommodating slot at the same time to eject the battery. The battery can be ejected smoothly, which further facilitates the robot to clamp the battery out.

[0033] In some embodiments, the transfer device further includes an adjustment mechanism disposed between the battery loading and unloading station and the turntable, and the adjustment mechanism is used to adjust the battery on the fixture so that the battery is assembled in place.

[0034] By setting up an adjustment mechanism, and locating it between the battery loading and unloading stations and the turntable, it is beneficial to shorten the moving distance of the first lifting mechanism and the drive module. The adjustment mechanism adjusts the battery on the fixture so that the battery is assembled in place, thereby improving the battery injection effect and thus improving the quality of the battery.

[0035] In some embodiments, the adjustment mechanism includes a mounting bracket disposed on the base and an adjustment member disposed on the mounting bracket, an adjustment area is formed below the mounting bracket, the adjustment member corresponds one-to-one to the batteries on the clamp, and moves along the height direction of the clamp to adjust the batteries on the clamp located in the adjustment area.

[0036] By setting the adjustment mechanism to include a mounting bracket and an adjustment member, an adjustment area is formed below the mounting bracket. The adjustment member moves along the height direction of the clamp to adjust the battery on the clamp located in the adjustment area so that the battery is assembled in place. The structure is simple and reliable.

[0037] In some embodiments, the transfer device further includes a robot for loading and unloading the fixture located at the battery loading and unloading station.

[0038] By setting up a robot to load and unload the fixture located at the battery loading and unloading station, it is beneficial to realize machine automation operation and reduce labor costs.

[0039] In some embodiments, the transfer device and the turntable are separate structures.

[0040] In this embodiment, it is convenient to separately process the transfer device and the turntable, thereby reducing the difficulty and cost of processing the transfer device and the turntable. In addition, it is also beneficial to maintain the transfer device.

[0041] In some embodiments, a fixture loading station, a vacuuming station, a liquid injection station, and a static station are sequentially arranged on the periphery of the turntable along the flow position of the fixture, and the transfer device is arranged on the fixture loading station.

[0042] While batteries are being loaded and unloaded at the battery loading and unloading stations, the vacuum pumping and liquid injection mechanisms can perform vacuuming and liquid injection operations at their respective corresponding vacuum pumping and liquid injection stations, saving waiting time at these stations and improving the processing efficiency of the liquid injection system. Placing the vacuum pumping and liquid injection stations outside the turntable also facilitates maintenance of components such as gas and valves in the liquid injection system.

[0043] A second aspect of an embodiment of the present disclosure provides a transfer device, which is used as a component of the above-mentioned injection system.

[0044] The liquid injection system of the disclosed embodiment is configured such that the fixture is detachably mounted to the mounting area of ​​the turntable. In this way, the battery can be loaded and unloaded by transferring the fixture to the outside of the turntable, which is beneficial for loading and unloading the battery (i.e., it is convenient to place the battery in or out of the fixture's receiving slot). To a certain extent, the interference between the manipulator and the turntable when loading and unloading the battery can be avoided. In addition, since the fixture and the turntable are detachably connected, it is also beneficial for the maintenance of the fixture, thereby facilitating the maintenance of the liquid injection system, and making it convenient to maintain and change the fixture. Furthermore, the fixture and the turntable are plugged into the first plug-in slot through the first plug-in connector. Whether for assembly or disassembly, only the fixture needs to move linearly in the plug-in direction or the opposite direction of the plug-in direction. The movement mode is single, and the fixture and the turntable can be quickly assembled and disassembled. The operation is convenient, the assembly efficiency of the fixture is improved, the assembly cost is reduced, and the machine is also automated. Moreover, the turntable can be simplified, the flexibility of the liquid injection system is improved, and rapid changeover is facilitated. Each fixture can be maintained in turn, reducing labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0059] In the description of the embodiments of the present disclosure, the orientations or positional relationships indicated by technical terms such as "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "circumferential", "height direction", "first direction", and "second direction" are based on the orientations or positional relationships shown in the accompanying drawings.

Therefore, they should not be understood as limiting the embodiments of the present disclosure.

[0060] In the description of the embodiments of the present disclosure, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal connectivity between two components or interaction between two components.

[0061] In the description of the embodiments of the present disclosure, unless otherwise clearly specified and limited, the technical term "contact" should be understood in a broad sense, and can be direct contact, contact through an intermediate medium layer, contact with essentially no interaction force between the two contacting parties, or contact with interaction force between the two contacting parties.

[0062] With the development of clean energy, more and more devices are using electricity as a driving force. Consequently, power batteries, such as lithium-ion batteries, that can store large amounts of electricity and undergo multiple charge and discharge cycles are rapidly developing. These batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in aerospace and other fields.

[0063] The battery referred to in the embodiments of this disclosure refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity. For example, the battery referred to in this disclosure may include a battery module or a battery pack. Batteries generally include a housing for enclosing one or more battery cells. The housing prevents liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0064] In the present disclosure, battery cells may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, and the present disclosure is not limited thereto. Battery cells may be cylindrical, rectangular, or in other shapes, and the present disclosure is not limited thereto.

[0065] A battery cell includes an electrode assembly and an electrolyte. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. A battery cell primarily operates by the movement of metal ions between the positive and negative electrode sheets. The positive electrode sheet includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive electrode collector. The uncoated positive electrode collector protrudes from the coated positive electrode collector, and the uncoated positive electrode collector serves as the positive electrode tab. For lithium-ion batteries, for example, the positive electrode current collector can be made of aluminum, and the positive electrode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide. The negative electrode sheet includes a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative electrode collector. The uncoated negative electrode collector protrudes from the coated negative electrode collector, and the uncoated negative electrode collector serves as the negative electrode tab. The negative electrode current collector can be made of copper, and the negative electrode active material can be carbon or silicon. To ensure high current flow without melting, multiple positive electrode tabs are stacked together, and multiple negative electrode tabs are stacked together. The separator can be made of materials such as PP (polypropylene) or PE (polyethylene).

[0066] A battery cell also includes an insulating film and a casing. The insulating film is applied to the outside of the electrode assembly, and the casing encapsulates the electrode assembly coated with the insulating film to form a battery cell. The insulating film can be Mylar film, and the casing can be aluminum. After the electrode assembly is wound, the Mylar film and casing are encapsulated through the Mylar wrapping process and the casing insertion process. The Mylar film seals and protects the electrode assembly, effectively insulating the electrode assembly and casing from each other, preventing internal short circuits in the battery cell. The casing also provides protection.

[0067] The injection process is an important step in the battery manufacturing process. The injection accuracy is directly related to the cycle performance and consistency of lithium ions.

[0068] In the related art, since the fixture is fixed on the turntable, when the fixture moves to the loading and unloading station, when the fixture is loaded and unloaded by the loading and unloading robot, there is an interference problem between the robot and the turntable, which makes loading and unloading inconvenient.

[0069] In order to facilitate loading and unloading, an embodiment of the present disclosure provides a battery injection system, which includes a rotatable turntable, a clamp for carrying batteries, and a transfer device. A plurality of installation areas are provided on the turntable, and each installation area is arranged at intervals along the circumference of the turntable. One of the turntable and the clamp is provided with a first plug-in slot, and the other is provided with a first plug-in component. The first plug-in component is plugged into and matched with the first plug-in slot along the height direction of the clamp to detachably install the clamp to the installation area. The clamp can move upward under the action of external force and detach from the turntable, and the turntable drives the clamp to rotate along the circumference of the turntable by rotation. The transfer device includes a base and a first lifting mechanism provided on the base. The first lifting mechanism is used to drive the clamp to move along the height direction of the clamp so that the clamp can be assembled to the turntable or detached from the turntable.

[0070] The injection system includes a rotatable turntable, a clamp for carrying batteries, and a transfer device. By detachably mounting the clamp to the mounting area of ​​the turntable, the battery can be loaded and unloaded by transferring the clamp to the outside of the turntable, which is beneficial to the loading and unloading of the battery (i.e., it is convenient to place the battery in or out of the receiving slot of the clamp). To a certain extent, the interference between the manipulator and the turntable when loading and unloading the battery can be avoided. In addition, since the clamp and the turntable are detachably connected, it is also beneficial to maintain the clamp, thereby facilitating the maintenance of the injection system, and making it convenient to maintain and change the clamp. Furthermore, the clamp and the turntable are plugged into and matched with the first plug-in slot through the first plug-in connector. Whether it is assembly or disassembly, it only requires the clamp to move linearly in the plug-in direction or the opposite direction of the plug-in direction. The movement mode is single, and the clamp and the turntable can be quickly assembled and disassembled. The operation is convenient, the assembly efficiency of the clamp is improved, the assembly cost is reduced, and the machine is also automated. Moreover, the turntable can be simplified, the flexibility of the injection system can be improved, and rapid mold change is convenient. The fixtures can be maintained in turn, reducing labor intensity.

[0071] 1 to 8 , an embodiment of the present disclosure further provides a transfer device 3 , which is used as a component of the injection system 100 of any embodiment of the present disclosure.

[0072] The transfer device 3 includes a base 31 and a first lifting mechanism 32 disposed on the base 31. The first lifting mechanism 32 is used to drive the clamp 2 to move along the height direction of the clamp 2, so that the clamp 2 can be assembled with or detached from the turntable 1. This facilitates the realization of automated operation of the machine.

[0073] The embodiment of the present disclosure provides a liquid injection system 100 for a battery 200, which includes a rotatable turntable 1, a fixture 2 for carrying the battery 200, and a transfer device 3. A plurality of mounting areas 1a are provided on the turntable 1, and each mounting area 1a is arranged at intervals along the circumference of the turntable 1. One of the turntable 1 and the fixture 2 is provided with a first plug-in slot 2a, and the other is provided with a first plug-in component. The first plug-in component is plugged into and matched with the first plug-in slot 2a along the height direction of the fixture 2 to detachably install the fixture 2 to the mounting area 1a. The fixture 2 can move upward under the action of an external force and detach from the turntable 1. The turntable 1 rotates to drive the fixture 2 to rotate along the circumference of the turntable 1. The transfer device 3 includes a base 31 and a first lifting mechanism 32 provided on the base 31. The first lifting mechanism 32 is used to drive the fixture 2 to move along the height direction of the fixture 2 so that the fixture 2 can be assembled to the turntable 1 or detached from the turntable 1.

[0074] The rotatable turntable 1 means that the turntable 1 can rotate under the action of an external force.

[0075] Referring to Figures 1 and 2 , the turntable 1 is provided with multiple mounting areas 1a, spaced apart along the circumference of the turntable 1. These mounting areas 1a are used to mount fixtures 2 for performing steps such as vacuuming, liquid injection, and resting the batteries 200 on the fixtures 2. The mounting areas 1a are spaced apart along the circumference of the turntable 1. This allows the turntable 1 to rotate, driving the fixtures 2 within the mounting areas 1a along the circumference of the turntable 1 to perform different steps and ultimately complete liquid injection.

[0076] It should be noted that the multiple mentioned in the embodiments of the present disclosure refers to a number of two or more than two.

[0077] Please refer to Figures 1, 2 and 8. One of the turntable 1 and the clamp 2 is provided with a first plug-in slot 2a, and the other is provided with a first connector (not shown in the figure). The first connector is plugged into and fitted with the first plug-in slot 2a along the height direction of the clamp 2 to detachably install the clamp 2 to the installation area 1a.

[0078] The fixture 2 is a structure used to support the battery 200. During the injection process, the battery 200 is supported by the receiving slot 2n of the fixture 2. Different mechanisms of the injection system 100 perform different treatments on the battery 200. Different batteries 200 may require different fixtures 2. Therefore, different fixtures 2 can be used to support different types of batteries 200.

[0079] It should be noted that one of the turntable 1 and the fixture 2 is provided with the first plug-in slot 2a, and the other is provided with the first plug-in component, which means that the turntable 1 can be provided with the first plug-in component and the fixture 2 is provided with the first plug-in slot 2a. Alternatively, the turntable 1 can be provided with the first plug-in slot 2a and the fixture 2 can be provided with the first plug-in component.

[0080] Of course, in other embodiments, the turntable 1 may be provided with a first connector and a first plug-in slot 2a, the fixture 2 may also be provided with a first connector and a first plug-in slot 2a, the first connector on the fixture 2 may be plugged into and matched with the first plug-in slot 2a on the turntable 1, and the first plug-in slot 2a on the fixture 2 may be plugged into and matched with the first connector on the turntable 1.

[0081] It should be noted that after the first connector is plugged into the first plug slot 2a, the first connector cannot rotate relative to the first plug slot 2a, and in the absence of other forces acting on the clamp 2, the clamp 2 can remain in the plugged position.

[0082] For example, the first connector is plugged into and engaged with the first insertion slot 2a along the height direction of the clamp 2, and the clamp 2 can move upward and disengage from the turntable 1 under the action of an external force. In this embodiment, during assembly, the clamp 2 is plugged into the turntable 1 from top to bottom. Thereafter, the weight of the clamp 2 helps to maintain the clamp 2 in the plugged position. Furthermore, when the turntable 1 drives the clamp 2 to rotate, the clamp 2 is substantially not subjected to an upward force. Therefore, even if the clamp 2 is not restricted from upward movement, the clamp 2 can still be relatively reliably maintained in the plugged position. In addition, the weight of the clamp 2 does not generate a horizontal force component on the clamp 2, which helps to increase the reliability of the clamp 2.

[0083] It should be noted that, referring to Figures 2 to 5, the transfer device 3 includes a base 31 and a first lifting mechanism 32 arranged on the base 31. The first lifting mechanism 32 is used to drive the clamp 2 to move along the height direction of the clamp 2 so that the clamp 2 can be assembled to the turntable 1 or detached from the turntable 1. That is to say, an upward force can be applied to the clamp 2 by the first lifting mechanism 32 of the transfer device 3 so that the clamp 2 can move along the height direction of the clamp 2 and detach from the turntable 1. During assembly, the first lifting mechanism 32 plugs the clamp 2 into the turntable 1 from top to bottom. Thereafter, the self-gravity of the clamp 2 is conducive to keeping the clamp 2 in the plug-in position, which is conducive to realizing automatic operation of the machine.

[0084] In some embodiments, the first insertion slot 2a is similar to a falcon groove, the structure of the first connector is similar to a tenon, and the matching relationship between the first insertion slot 2a and the first connector is similar to a mortise and tenon structure. In this way, there is no need for fasteners such as screws to connect, and the turntable 1 and the clamp 2 can be reliably connected through the mortise and tenon structure.

[0085] The embodiment of the present disclosure provides a liquid injection system 100 for a battery 200, which includes a rotatable turntable 1, a fixture 2 for carrying the battery 200, and a transfer device 3. By detachably mounting the fixture 2 to the mounting area 1a of the turntable 1, the battery 200 can be loaded and unloaded by transferring the fixture 2 to the outside of the turntable 1, which is beneficial for loading and unloading the battery 200 (i.e., it is convenient to place the battery 200 into or remove the receiving slot 2n of the fixture 2). To a certain extent, it can avoid interference between the manipulator 37 and the turntable 1 when loading and unloading the battery 200. In addition, since the fixture 2 is detachably connected to the turntable 1, it is also beneficial for maintenance of the fixture 2, thereby facilitating maintenance and replacement of the fixture 2. Furthermore, the fixture 2 and the turntable 1 are plugged into each other via the first plug-in member and the first plug-in slot 2a. Whether assembled or disassembled, the fixture 2 only requires linear movement in the plug-in direction or the opposite direction. This single movement method enables rapid assembly and disassembly of the fixture 2 and the turntable 1, facilitating convenient operation and improving the assembly efficiency of the fixture 2, thereby reducing assembly costs and facilitating automated machine operation. Furthermore, the turntable 1 can be simplified, increasing the flexibility of the injection system 100 and facilitating rapid changeovers. Each fixture 2 can be maintained in turn, reducing labor intensity.

[0086] It should be noted that the specific cooperation relationship between the first lifting mechanism 32 and the clamp 2 is not limited here, as long as it can drive the clamp 2 to move along the height direction of the clamp 2.

[0087] In some embodiments, the first lifting mechanism 32 is supported on the bottom of the clamp 2 .

[0088] By supporting the first lifting mechanism 32 at the bottom of the fixture 2, the coordination between the first lifting mechanism 32 and the fixture 2 is further facilitated, and the space required for the movement of the first lifting mechanism 32 is reduced, thereby improving the compactness of the injection system 100. For example, the first lifting mechanism 32 does not need to be wrapped around or supported by the side wall of the fixture 2, which can reduce the space required on the side of the fixture 2.

[0089] In some more specific embodiments, the turntable 1 includes a carrier 1b for supporting the clamp 2. There are two first lifting mechanisms 32. The two first lifting mechanisms 32 are spaced apart and abut against the clamp 2 to avoid the carrier 1b.

[0090] The turntable 1 includes a supporting member 1 b for supporting the clamp 2 , and the supporting members 1 b are arranged at intervals between adjacent mounting areas 1 a .

[0091] There are two first jacking mechanisms 32, and the two first jacking mechanisms 32 are arranged at intervals and abut against the clamp 2 to avoid the carrier 1b. For example, the two first jacking mechanisms 32 abut against the bottom of the clamp 2 respectively, which improves the cooperation stability between the first jacking mechanism 32 and the clamp 2. During assembly, the first jacking mechanism 32 can first move the clamp 2 to the top of the carrier 1b, and then move the clamp 2 from top to bottom so that the clamp 2 and the base are plugged into and matched with the first connector through the first connector slot 2a. At this time, the carrier 1b is located between the two first jacking mechanisms 32, that is, the gap between the two first jacking mechanisms 32 is used to avoid the carrier 1b, or, the gap between the carriers 1b between adjacent installation areas 1a is used to avoid the first jacking mechanism 32.

[0092] In some more specific embodiments, the turntable 1 includes two supporting members 1b for supporting the clamp 2, and there is one first lifting mechanism 32. The two supporting members 1b are spaced apart to avoid the first lifting mechanism 32. The first lifting mechanism 32 abuts against the middle of the clamp 2.

[0093] In some embodiments, referring to Figures 3 to 5 and 8, one of the first lifting mechanism 32 and the clamp 2 is provided with a second plug-in slot 2b, and the other is provided with a second connector 32a, and the second connector 32a is plugged into the second plug-in slot 2b along the height direction of the clamp 2.

[0094] It should be noted that one of the first lifting mechanism 32 and the clamp 2 is provided with the second plug-in slot 2b, and the other is provided with the second plug-in connector 32a. This means that the first lifting mechanism 32 can be provided with the second plug-in connector 32a, and the clamp 2 can be provided with the second plug-in slot 2b. Alternatively, the first lifting mechanism 32 can be provided with the second plug-in slot 2b, and the clamp 2 can be provided with the second plug-in connector 32a.

[0095] Of course, in other embodiments, the first lifting mechanism 32 may be provided with a second connector 32a and a second plug-in slot 2b, and the clamp 2 may also be provided with a second connector 32a and a second plug-in slot 2b, and the second connector 32a on the clamp 2 may be plugged into and matched with the second plug-in slot 2b on the first lifting mechanism 32, and the second plug-in slot 2b on the clamp 2 may be plugged into and matched with the second connector 32a on the first lifting mechanism 32.

[0096] It should be noted that after the second connector 32a is plugged into the second plug slot 2b, the second connector 32a cannot rotate relative to the second plug slot 2b, and the clamp 2 can remain in the plugged position in the absence of other forces acting on the clamp 2.

[0097] For example, the second connector 32a is plugged into and matched with the second insertion slot 2b along the height direction of the clamp 2. In this embodiment, during assembly, the first lifting mechanism 32 is plugged into the clamp 2 from bottom to top. Thereafter, the self-weight of the clamp 2 helps to keep the clamp 2 in the plugged position. In addition, when the first lifting mechanism 32 drives the clamp 2 to move along the height direction of the clamp 2, the self-weight of the clamp 2 helps to keep the clamp 2 in the plugged position. Therefore, even if the clamp 2 is not limited to move upward, the clamp 2 can be relatively reliably maintained in the plugged position. In addition, the gravity of the clamp 2 will not generate a component force on the clamp 2 in the horizontal direction, which helps to increase the reliability of the clamp 2. The cooperation between the second connector 32a and the second insertion slot 2b can limit the clamp 2 in the horizontal direction.

[0098] In some embodiments, the second insertion slot 2b is similar to a falcon groove, and the structure of the second connector 32a is similar to a tenon. The matching relationship between the second insertion slot 2b and the second connector 32a is similar to a mortise and tenon structure. In this way, there is no need for fasteners such as screws to connect, and the first lifting mechanism 32 and the clamp 2 can be reliably connected through the mortise and tenon structure.

[0099] In some embodiments, referring to Figures 1 to 5, the transfer device 3 also includes a driving module 33 and a battery loading and unloading station 34. The driving module 33 is used to drive the first jacking mechanism 32 to move along the first direction. The battery loading and unloading station 34 is arranged on the side of the transfer device 3 away from the turntable 1 along the first direction. The first jacking mechanism 32 can move the fixture 2 away from the battery loading and unloading station 34 or transfer the fixture 2 to the battery loading and unloading station 34, wherein the first direction is perpendicular to the height direction.

[0100] The specific type of the drive module 33 is not limited here. For example, it can be a rotating motor screw nut structure, or an iron core linear motor drive structure, or an ironless linear motor drive structure, or a voice coil motor drive structure, or other drive forms.

[0101] The battery loading and unloading station 34 is used to load and unload the batteries 200 .

[0102] The battery loading and unloading station 34 is arranged on the side of the transfer device 3 away from the turntable 1 along the first direction, and the driving module 33 is used to drive the first lifting mechanism 32 to move along the first direction, that is, to drive the clamp 2 to move between the turntable 1 and the battery loading and unloading station 34.

[0103] The first lifting mechanism 32 can move the fixture 2 away from the battery loading and unloading station 34 or transfer the fixture 2 to the battery loading and unloading station 34. The first lifting mechanism 32 drives the fixture 2 to move along the height direction of the fixture 2 so that the fixture 2 can be assembled to the battery loading and unloading station 34 or detached from the battery loading and unloading station 34.

[0104] The transfer device 3 is provided with a driving module 33 and a battery loading and unloading station 34. The driving module 33 is used to drive the clamp 2 to move between the turntable 1 and the battery loading and unloading station 34. In this way, the clamp 2 can be driven by the first jacking mechanism 32 to move along the height direction of the clamp 2 to make the clamp 2 disengage from the turntable 1, and then the clamp 2 can be driven by the driving module 33 to move along the first direction to move the clamp 2 to the battery loading and unloading station 34. The first jacking mechanism 32 drives the clamp 2 to move along the height direction of the clamp 2 to make the clamp 2 assembled on the battery loading and unloading station 34. That is to say, the transfer device 3 can transfer the clamp 2 to the battery loading and unloading station 34 outside the turntable 1 and then load and unload the battery 200, which is beneficial to the loading and unloading of the battery 200 (that is, it is convenient to place the battery 200 into or out of the receiving slot 2n of the clamp 2), and to a certain extent, it can avoid interference between the manipulator 37 and the turntable 1 when loading and unloading the battery 200. After the battery 200 is re-loaded on the fixture 2, the first lifting mechanism 32 drives the fixture 2 to move along the height direction of the fixture 2 to make the fixture 2 separate from the battery loading and unloading station 34, and then drives the fixture 2 to move along the first direction through the driving module 33 to move the fixture 2 onto the turntable 1. The first lifting mechanism 32 drives the fixture 2 to move along the height direction of the fixture 2 to make the fixture 2 assembled on the turntable 1.

[0105] In some embodiments, referring to Figures 3 to 5 and 8, one of the battery loading and unloading stations 34 and the fixture 2 is provided with a third plug-in slot 2c, and the other is provided with a third connector 34a, and the third connector 34a is plugged into and matched with the third plug-in slot 2c along the height direction of the fixture 2.

[0106] It should be noted that one of the battery loading and unloading station 34 and the fixture 2 is provided with the third plug-in slot 2c, and the other is provided with the third plug-in connector 34a. This means that the battery loading and unloading station 34 can be provided with the third plug-in connector 34a, and the fixture 2 can be provided with the third plug-in slot 2c. Alternatively, the battery loading and unloading station 34 can be provided with the third plug-in slot 2c, and the fixture 2 can be provided with the third plug-in connector 34a.

[0107] Of course, in other embodiments, the battery loading and unloading station 34 may be provided with a third connector 34a and a third plug-in slot 2c, and the fixture 2 may also be provided with a third connector 34a and a third plug-in slot 2c. The third connector 34a on the fixture 2 is plugged into and matched with the third plug-in slot 2c on the battery loading and unloading station 34, and the third plug-in slot 2c on the fixture 2 is plugged into and matched with the third connector 34a on the battery loading and unloading station 34.

[0108] It should be noted that after the third connector 34a is plugged into the third plug slot 2c, the third connector 34a cannot rotate relative to the third plug slot 2c, and the clamp 2 can remain in the plugged position in the absence of other forces acting on the clamp 2.

[0109] For example, the third connector 34a is plugged into the third connector slot 2c along the height direction of the fixture 2, and the fixture 2 can move upward and disengage from the battery loading and unloading station 34 under the action of an external force. In this embodiment, during assembly, the fixture 2 is plugged into the battery loading and unloading station 34 from top to bottom. Thereafter, the weight of the fixture 2 helps to maintain the fixture 2 in the plugged position. In addition, when the battery loading and unloading station 34 drives the fixture 2 to rotate, the fixture 2 is basically not subjected to an upward force. Therefore, even if the fixture 2 is not limited in its upward movement, the fixture 2 can still be relatively reliably maintained in the plugged position. In addition, the weight of the fixture 2 does not generate a horizontal force component on the fixture 2, which helps to increase the reliability of the fixture 2.

[0110] It should be noted that the transfer device 3 includes a base 31 and a first lifting mechanism 32 arranged on the base 31. The first lifting mechanism 32 is used to drive the clamp 2 to move along the height direction of the clamp 2 so that the clamp 2 can be assembled to the battery loading and unloading station 34 or detached from the battery loading and unloading station 34. That is to say, the first lifting mechanism 32 of the transfer device 3 can apply an upward force to the clamp 2 so that the clamp 2 moves along the height direction of the clamp 2 and detaches from the battery loading and unloading station 34. During assembly, the first lifting mechanism 32 plugs the clamp 2 from top to bottom into the battery loading and unloading station 34. Thereafter, the self-gravity of the clamp 2 is conducive to keeping the clamp 2 in the plug-in position, which is conducive to realizing automatic operation of the machine.

[0111] In some embodiments, the third plug-in slot 2c is similar to a falcon groove, and the structure of the third connector 34a is similar to a tenon. The matching relationship between the third plug-in slot 2c and the third connector 34a is similar to a mortise and tenon structure. In this way, there is no need for fasteners such as screws to connect, and the battery loading and unloading station 34 and the fixture 2 can be reliably connected through the mortise and tenon structure.

[0112] It is understandable that the clamp 2 can be provided with different plug-in slots to cooperate with the battery loading and unloading station 34 and the turntable 1 respectively, or the same plug-in slot can be provided to cooperate with the battery loading and unloading station 34 or the turntable 1 respectively.

[0113] In some embodiments, referring to FIG. 8 , the first inserting slot 2 a and the third inserting slot 2 c are disposed on the fixture 2 and are the same inserting slot on the fixture 2 .

[0114] In this embodiment, the fixture 2 is provided with the same plug-in slot to cooperate with the battery loading and unloading station 34 or the turntable 1 respectively. That is to say, the battery loading and unloading station 34 and the turntable 1 can share the plug-in slot on the fixture 2, so that the fixture 2 can reduce the setting of the plug-in slot, which is beneficial to improving the processing efficiency of the fixture 2 and improving the structural strength of the fixture 2.

[0115] In some embodiments, referring to Figures 3 to 4 and Figure 6, the transfer device 3 includes a second lifting mechanism 35 disposed below the battery loading and unloading station 34, and the second lifting mechanism 35 is used to eject the battery 200 in the fixture 2 located on the battery loading and unloading station 34.

[0116] It is understandable that the battery 200 is accommodated in the accommodation groove 2n of the clamp 2, and the clamp 2 plays a role in protecting the battery 200 and facilitating the transfer of the battery 200.

[0117] By setting up a second lifting mechanism 35, it is used to eject the battery 200 in the clamp 2 located on the battery loading and unloading station 34. That is to say, the second lifting mechanism 35 is used to eject the battery 200 in the accommodating groove 2n, which is beneficial for the robot 37 to clamp the battery 200, so as to facilitate the unloading of the battery 200.

[0118] It should be noted that there are many specific ways for the second lifting mechanism 35 to cooperate with the clamp 2 and eject the battery 200, which are not limited here.

[0119] For example, a first avoidance groove 2d is provided at the bottom of the fixture 2, and a second avoidance groove 34b corresponding to the first avoidance groove 2d is provided at the battery loading and unloading station 34. The ejector rod 35a of the second lifting mechanism 35 moves along the height direction of the fixture 2, and extends into the fixture 2 through the second avoidance groove 34b and the first avoidance groove 2d in turn, and ejects the battery 200 in the fixture 2.

[0120] A first avoidance groove 2d is provided at the bottom of the clamp 2, that is, a first avoidance groove 2d is provided at the bottom of the accommodating groove 2n, for allowing the ejector rod 35a to extend into the accommodating groove 2n through the first avoidance groove 2d to eject the battery 200 in the accommodating groove 2n.

[0121] The battery loading and unloading station 34 is provided with a second avoidance groove 34b corresponding to the first avoidance groove 2d, that is, the first avoidance groove 2d corresponds to the second avoidance groove 34b one-to-one, and is used to allow the ejector rod 35a to pass through the battery loading and unloading station 34 through the second avoidance groove 34b, and then extend into the accommodating groove 2n through the first avoidance groove 2d to eject the battery 200 in the accommodating groove 2n.

[0122] By opening a first avoidance groove 2d at the bottom of the clamp 2, the battery loading and unloading station 34 is provided with a second avoidance groove 34b corresponding to the first avoidance groove 2d, so that the push rod 35a of the second lifting mechanism 35 can extend into the clamp 2 through the second avoidance groove 34b and the first avoidance groove 2d in turn, and push out the battery 200 in the clamp 2. The structure is simple and reliable.

[0123] In some embodiments, referring to FIG. 4 , FIG. 7 and FIG. 8 , the first avoidance grooves 2 d extend along the first direction, and there are multiple first avoidance grooves 2 d . The first avoidance grooves 2 d are arranged along the second direction, and the first direction and the second direction intersect.

[0124] The first direction and the second direction intersect, which means that the first direction and the second direction are not parallel in the same plane. For example, the first direction and the second direction are perpendicular to each other.

[0125] The first avoidance groove 2d extends along the first direction. Exemplarily, the accommodating groove 2n also extends along the first direction, that is, the first avoidance groove 2d and the accommodating groove 2n extend in the same direction. This is beneficial for the ejector rod 35a to cooperate with the battery 200.

[0126] It should be noted that there are multiple accommodating grooves 2n in the clamp 2, and the multiple accommodating grooves 2n are arranged along the second direction. In this way, the clamp 2 can be provided with multiple accommodating grooves 2n to accommodate multiple batteries 200 at the same time, which is beneficial to the transfer of the batteries 200.

[0127] By setting the number of the first avoidance grooves 2d to be multiple and the first avoidance grooves 2d are arranged along the second direction, multiple batteries 200 can be ejected simultaneously, which is beneficial to improving the material removal efficiency of the batteries 200.

[0128] Correspondingly, there are multiple second avoidance grooves 34 b , and each second avoidance groove 34 b is arranged along the second direction. In this way, multiple batteries 200 can be ejected simultaneously, which is beneficial to improving the material removal efficiency of the batteries 200 .

[0129] In some embodiments, referring to Figures 4, 7, and 8, the first avoidance groove 2d extends along the first direction. There are multiple push rods 35a in each first avoidance groove 2d, and the push rods 35a in the same first avoidance groove 2d are spaced apart along the first direction.

[0130] Exemplarily, the battery 200 extends along a first direction, that is, the length direction of the battery 200 is the first direction, and the plurality of batteries 200 are arranged along a second direction.

[0131] In order to push out the battery 200 more smoothly, multiple push rods 35a can be set in each first avoidance groove 2d, and the push rods 35a in the same first avoidance groove 2d are arranged along the length direction of the battery 200, which can improve the stability of the battery 200 in the height direction.

[0132] Exemplarily, the number of push rods 35a in each first avoidance groove 2d is two.

[0133] By setting the number of push rods 35a to be multiple, each push rod 35a is arranged at intervals along the first direction, that is, multiple push rods 35a can cooperate with the battery 200 in the accommodating groove 2n at the same time to push the battery 200 out. The battery 200 can be pushed out smoothly, which further facilitates the robot 37 to clamp the battery 200 out.

[0134] It is understandable that during the loading process, some batteries 200 may not be fully assembled into place (ie, not fully assembled into the receiving groove 2n), which is not conducive to subsequent steps such as liquid injection.

[0135] In some embodiments, referring to FIG. 3 and FIG. 4 , the transfer device 3 further includes an adjustment mechanism 36 disposed between the battery loading and unloading station 34 and the turntable 1 , and the adjustment mechanism 36 is used to adjust the battery 200 on the fixture 2 so that the battery 200 is assembled in place.

[0136] The transfer device 3 also includes an adjustment mechanism 36 arranged between the battery loading and unloading station 34 and the turntable 1. That is to say, the transfer device 3 will pass through the adjustment mechanism 36 during the process of transferring the fixture 2, which is conducive to the adjustment mechanism 36 to adjust the battery 200 on the fixture 2 so that the battery 200 can be assembled in place.

[0137] By setting up the adjustment mechanism 36 and locating it between the battery loading and unloading station 34 and the turntable 1, it is beneficial to shorten the moving distance of the first lifting mechanism 32 and the driving module 33. The adjustment mechanism 36 adjusts the battery 200 on the clamp 2 so that the battery 200 is assembled in place, thereby improving the liquid injection effect of the battery 200 and thus improving the quality of the battery 200.

[0138] It should be noted that the specific type of the adjustment mechanism 36 is not limited here.

[0139] For example, in some embodiments, the adjustment mechanism 36 includes a mounting bracket 361 disposed on the base 31 and an adjustment member 362 disposed on the mounting bracket 361. An adjustment area 36a is formed below the mounting bracket 361. The adjustment member 362 corresponds one-to-one with the battery 200 on the fixture 2 and adjusts the battery 200 on the fixture 2 located in the adjustment area 36a by moving along the height direction of the fixture 2.

[0140] The specific type of the mounting bracket 361 is not limited here. Exemplarily, the mounting bracket 361 is gantry-shaped, so that an adjustment area 36 a is formed below the mounting bracket 361 . The mounting bracket 361 is used to carry the adjustment member 362 .

[0141] The specific type of the adjusting member 362 is not limited here. The adjusting member 362 is in the shape of a strip extending along the first direction, that is, extending along the length direction of the battery 200. The adjusting member 362 has protruding adjusting parts at both ends along the first direction, which is conducive to adjusting the battery 200.

[0142] It should be noted that the specific manner in which the adjusting member 362 moves along the height direction of the clamp 2 is not limited herein, for example, it may be driven by a linear module.

[0143] The driving module 33 moves the clamp 2 on the first lifting mechanism 32 from the battery loading and unloading station 34 to the adjustment area 36a, and the adjustment member 362 moves from top to bottom to adjust the battery 200 on the clamp 2 located in the adjustment area 36a so that the battery 200 is assembled in place.

[0144] By setting the adjustment mechanism 36 to include a mounting bracket 361 and an adjustment member 362, an adjustment area 36a is formed below the mounting bracket 361. The adjustment member 362 moves along the height direction of the clamp 2 to adjust the battery 200 on the clamp 2 located in the adjustment area 36a so that the battery 200 is assembled in place. The structure is simple and reliable.

[0145] In some embodiments, referring to FIG. 1 to FIG. 4 , the transfer device 3 further includes a robot 37 for loading and unloading the fixture 2 located on the battery loading and unloading station 34 .

[0146] It should be noted that the specific type and position of the robot 37 are not limited here, as long as it can load and unload the clamp 2 located on the battery loading and unloading station 34.

[0147] Exemplarily, the robot arm 37 is disposed on the base 31 .

[0148] By providing a manipulator 37 for loading and unloading the clamp 2 located on the battery loading and unloading station 34, it is beneficial to realize the automatic operation of the machine and reduce labor costs.

[0149] In some embodiments, the transfer device 3 and the turntable 1 are separate structures.

[0150] The transfer device 3 and the turntable 1 are of a split structure, which means that the transfer device 3 and the turntable 1 are not integrally formed, that is, the transfer device 3 and the turntable 1 are used as two independent components.

[0151] In this embodiment, it is convenient to separately process the transfer device 3 and the turntable 1 , thereby reducing the difficulty and cost of processing the transfer device 3 and the turntable 1 . In addition, it is also beneficial to maintain the transfer device 3 .

[0152] In some embodiments, referring to Figures 1 and 2, a fixture loading station 100a, a vacuuming station, a liquid injection station and a static station are sequentially arranged along the flow position of the fixture 2 on the periphery of the turntable 1, and the transfer device 3 is arranged on the fixture loading station 100a.

[0153] The fixture loading station 100 a is used to load and unload the fixture 2 , that is, to detachably mount the fixture 2 to the mounting area 1 a of the turntable 1 .

[0154] The vacuum station is used to vacuum the battery 200 in the fixture 2 located at the station.

[0155] The liquid injection station is used to inject liquid into the battery 200 in the fixture 2 located at the station.

[0156] The rest station is used to place the battery 200 in the fixture 2 at the station at rest.

[0157] Exemplarily, the liquid injection system 100 further includes a vacuum pumping mechanism and a liquid injection mechanism, which are respectively arranged at the vacuum pumping station and the liquid injection station, significantly reducing the length of the liquid injection system 100 and occupying a smaller area. After the battery 200 is injected, the fixture 2 can be placed at a resting station to ensure that the battery 200 is kept at rest, so that the electrolyte is in full contact with the internal electrode of the battery 200 and the performance of the battery 200 is guaranteed. When the battery 200 is loaded and unloaded at the battery 200 loading station and the battery 200 unloading station, the vacuum pumping mechanism and the liquid injection mechanism can perform vacuum pumping and liquid injection operations at their respective corresponding vacuum pumping station and liquid injection station, saving waiting time at the vacuum pumping station and the liquid injection station and improving the processing efficiency of the liquid injection system 100. Placing the vacuum pumping station and the liquid injection station outside the turntable 1 also facilitates the maintenance of components such as gas and valves in the liquid injection system 100.
