[0001] This utility model relates to the field of battery processing equipment technology, and in particular to an electrolyte injection device for battery processing. Background Technology

[0002] Electrolyte filling is a crucial step in battery manufacturing. Current electrolyte filling equipment has several shortcomings. Most devices cannot achieve continuous filling, requiring frequent shutdowns for battery loading and unloading, severely impacting production efficiency. Furthermore, some devices experience electrolyte backflow during filling, leading to inaccurate filling volumes and affecting battery quality. In addition, some filling devices have complex structures, are inconvenient to operate, and have high maintenance costs, hindering large-scale industrial production.

[0003] Therefore, this application provides an electrolyte injection device for battery processing to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide an electrolyte injection device for battery processing, which aims to solve the problems of low injection efficiency, inaccurate injection volume, complex operation and high maintenance cost of existing electrolyte injection devices for battery processing.

[0005] To achieve the above objectives, this application provides the following technical solution: an electrolyte injection device for battery processing, comprising a worktable, a turntable, a support, a distribution box, a guide cover, and a push rod.

[0006] The workbench has a motor at its bottom and a turntable at its top. The turntable is mounted on the turntable and has a guide plate at its bottom. Battery slots are evenly distributed on the side wall of the guide plate. The guide plate is used to transfer batteries. The turntable is driven by the motor, which drives the turntable to rotate, thereby driving the guide plate to rotate and realizing the continuous transfer of batteries.

[0007] The support is located on the top of the turntable. There are multiple sets of the support arranged in a circular array around the axis of the turntable. The end of the support is provided with a liquid injection cylinder. The bottom of the liquid injection cylinder is provided with a liquid injection pipe and a liquid extraction pipe. The position of the liquid injection pipe corresponds to that of the battery slot. The arrangement of multiple sets of the support and the liquid injection cylinder allows for simultaneous liquid injection operations on multiple batteries, thereby improving the liquid injection efficiency.

[0008] The top of the turntable is equipped with the distribution box, and the top of the distribution box is connected to the inlet pipe through a rotary joint. The distribution box is connected to the suction pipe through a delivery pipe. There are multiple sets of delivery pipes. The electrolyte flows unidirectionally from the distribution box to the injection cylinder. A unidirectional flow guide mechanism is provided between the injection cylinder and the injection pipe. The rotary joint ensures that the inlet pipe can continuously supply electrolyte when the turntable rotates. The unidirectional flow design avoids electrolyte backflow and ensures accurate injection volume.

[0009] The guide cover is installed outside the turntable. The bottom of the guide cover cooperates with the battery slot to guide the battery. There are material passage holes on both the left and right sides of the guide cover. The guide cover guides the battery to ensure that the battery accurately enters and leaves the battery slot and moves with the battery slot.

[0010] The top of the injection cylinder is slidably connected to the push rod, and the bottom of the push rod is provided with a piston. The piston is slidably connected in the injection cylinder. When the push rod rotates with the turntable, it moves up and down along the inner wall of the guide cover. The up and down movement of the push rod drives the piston to move, thereby realizing the extraction and injection of electrolyte.

[0011] Furthermore, the top of the injection cylinder is provided with a guide sleeve and an air hole, and the side wall of the push rod is provided with a guide bar. The push rod is slidably connected in the guide sleeve, and the guide bar is adapted to the guide sleeve. The cooperation between the guide sleeve and the guide bar ensures the stability of the push rod sliding. The air hole is used to balance the air pressure in the injection cylinder.

[0012] Furthermore, a support strip is provided on the rear inner wall of the guide cover, and a pressure strip is provided on the front inner wall of the guide cover. The two ends of the support strip and the pressure strip are positioned opposite each other. A guide wheel is provided on the top of the push rod. The guide wheel can roll along the top surface of the support strip and the bottom surface of the pressure strip. Both the support strip and the pressure strip are provided with helical sections. The helical sections on the support strip and the pressure strip enable the push rod to move up and down when the turntable rotates.

[0013] Furthermore, the one-way flow guiding mechanism includes a one-way chamber and a baffle. The one-way chamber is provided between the injection cylinder and the injection pipe, and a flow passage is provided between the injection cylinder and the one-way chamber. The baffle is connected to one side of the bottom of the flow passage. The baffle is made of flexible material. When the piston descends, the pressure inside the injection cylinder increases, pushing the baffle to open, and the electrolyte enters the one-way chamber and is injected into the battery through the injection pipe. When the piston rises, the baffle closes to prevent electrolyte backflow.

[0014] Furthermore, a one-way valve is connected to the bottom of the distribution box. There are multiple sets of one-way valves, and each set of one-way valves is connected to the liquid extraction pipe through the liquid delivery pipe. The one-way valve ensures that the electrolyte can only flow from the distribution box to the liquid injection cylinder, thus preventing backflow.

[0015] Furthermore, the support is arranged radially along the turntable and the bottom of the support is provided with a through groove, which is used to pass through the liquid delivery pipe and serves to fix and protect the liquid delivery pipe.

[0016] Furthermore, a feed guide plate is provided at the feed hole on the left side, and a discharge guide plate is provided at the feed hole on the right side. The feed guide plate and the discharge guide plate facilitate the entry and exit of the battery.

[0017] In summary, the technical effects and advantages of this utility model are as follows:

[0018] 1. Achieve continuous liquid injection: The turntable and guide plate are driven by a motor to rotate, and with the help of multiple sets of injection cylinders, the battery can be continuously injected with liquid without frequent shutdowns, which greatly improves the injection efficiency.

[0019] 2. Accurate electrolyte injection: A one-way flow guide mechanism and a one-way valve are set up to effectively prevent electrolyte backflow. The mechanical cooperation between the push rod and the support plate and pressure plate limits the stroke of the push rod, ensuring the accuracy of the electrolyte injection volume each time and improving the quality of the battery.

[0020] 3. Easy to operate: The device has a reasonable structural design, with each component working together and a high degree of automation, which reduces the difficulty of operation.

[0021] 4. Easy maintenance: The groove at the bottom of the support protects the liquid delivery pipe, and the connection of each component is simple, making it easy to maintain and replace. Attached Figure Description

[0040] As one implementation method in this embodiment, to achieve unidirectional flow of electrolyte from the distribution box 4 to the extraction tube 52, such as... Figure 4 , Figure 6 As shown, twelve sets of one-way valves 41 are evenly connected to the bottom of the diversion box 4, and each set of one-way valves 41 is connected to the extraction pipe 52 through the liquid delivery pipe 6.

[0042] As one implementation method in this embodiment, to facilitate feeding and discharging, such as Figure 1 , Figure 3 As shown, a feed guide plate 83 is provided at the left feed hole 80, and a discharge guide plate 84 is provided at the right feed hole 80.

[0043] The working principle of this utility model is as follows: When the electrolyte injection device for battery processing is working, the motor 10 starts and drives the turntable 11 on the top of the worktable 1 to rotate, which in turn drives the guide plate 20 on the turntable 2 to rotate. The battery enters from the feed guide plate 83 at the feed hole 80 on the left side. Under the guidance of the bottom of the guide cover 8 and the battery slot 21, the battery enters the battery slot 21 of the guide plate 20 and rotates with the guide plate 20. At the same time, the diversion box 4 rotates with the turntable 2, and the rotary joint 40 maintains normal electrolyte supply.

[0044] As the turntable 2 rotates, it drives the supports 3, which are arranged in a circular array around its axis, to rotate as well. The injection cylinder 5 at the end of the supports 3 also rotates. During the rolling of the guide wheel 72 on the push rod 7 at the top of the injection cylinder 5 along the top surface of the support strip 81 on the inner wall of the guide cover 8, the guide wheel 72 rises due to the spiral section on the support strip 81, causing the push rod 7 to rise and pull the piston 70 in the injection cylinder 5 upwards. This process reduces the pressure inside the injection cylinder 5, and the baffle 501 in the one-way chamber 50 blocks the flow hole under pressure. Due to the low pressure inside the injection cylinder 5, electrolyte enters the injection cylinder 5 from the distribution box 4 through the delivery pipe 6 and the extraction pipe 52. The distribution box 4 continuously replenishes the electrolyte through the top rotary joint 40 and the inlet pipe 9 until the guide wheel 72 moves to the end of the support strip 81 with the rotation, the push rod 7 stops rising, and the injection cylinder 5 stops moving. Continue extracting electrolyte; when the guide wheel 72 on the push rod 7 moves to the position of the pressure bar 82, the guide wheel 72 rolls at the bottom of the pressure bar 82. Since the pressure bar 82 has a spiral section, the guide wheel 72 lowers accordingly, driving the push rod 7 to press down and push the piston 70 downward. When the piston 70 descends, the pressure inside the injection cylinder 5 increases. Due to the presence of the one-way valve 41, the electrolyte in the injection cylinder 5 cannot flow back from the extraction pipe 52. Therefore, the baffle 501 in the one-way chamber 50 is pushed open, and the electrolyte enters the one-way chamber 50 through the flow hole, and then is injected into the battery in the battery slot 21 through the injection pipe 51 until the guide wheel 72 moves to the end of the pressure bar 82 and stops falling. The electrolyte in the injection cylinder 5 is completely injected into the battery. After the injection is completed, the battery continues to rotate with the guide plate 20 and is sent out from the discharge guide plate 84 at the right-side material passage hole 80.

[0045] Throughout the process, the guide sleeve 53 at the top of the injection cylinder 5 cooperates with the guide bar 71 on the push rod 7 to ensure the stability of the sliding of the push rod 7; the air hole 54 is used to balance the air pressure inside the injection cylinder 5; the tube groove at the bottom of the support 3 plays a role in fixing and protecting the delivery pipe 6.
