Description

Technical Field

[0001] This utility model relates to the field of lithium battery equipment technology, and in particular to a liquid injection tray, a liquid injection feeding device, and a liquid injection equipment. Background Technology

[0002] Electrolyte injection is a crucial step in lithium battery production, requiring the precise amount of electrolyte to be injected into the casing and wet the battery cells. Batteries awaiting injection are typically first loaded onto an injection tray, then transferred by the tray to the injection device for injection. To improve efficiency, the injection tray can usually hold multiple batteries simultaneously. Currently, battery loading is usually done by a robotic arm that picks up batteries one by one from the battery conveyor line and transfers them to the tray, resulting in a cumbersome and inefficient loading process. Utility Model Content

[0003] Therefore, it is necessary to provide a liquid injection tray, liquid injection feeding device, and liquid injection equipment that can improve the feeding efficiency in response to the above problems.

[0004] A liquid injection tray includes a tray body and a switch assembly; the surface of the tray body is formed with a plurality of first grooves, and at least one end of the first grooves extending in the direction of extension is provided with an inlet; the switch assembly includes a stop member disposed corresponding to the first groove, and each stop member is operable to move relative to the tray body to move into or out of the range of the inlet of the corresponding first groove.

[0005] In one embodiment, a guide plate is provided on at least one side of the first groove in the width direction, and the guide plate extends along the length direction of the first groove.

[0006] In one embodiment, a second groove is formed at the bottom of the first groove, and the second groove extends along the length direction of the first groove.

[0007] In one embodiment, the first groove is elongated, and multiple first grooves are arranged side by side. The switch assembly also includes a connector, and the abutments corresponding to the multiple first grooves are all connected to the connector.

[0008] In one embodiment, the connector extends along a parallel direction of a plurality of the first grooves and is movable relative to the tray body along the parallel direction.

[0009] In one embodiment, the injection tray further includes a pushing component disposed at one end of the connector and capable of pushing the connector to move along the parallel direction.

[0010] In one embodiment, the switch assembly further includes an elastic element that is connected to the tray body along with the connector.

[0011] In one embodiment, the elastic element includes a compression spring disposed at the end of the connector away from the push assembly and a tension spring disposed at the end of the connector near the push assembly.

[0012] In one embodiment, the pushing component includes a first driving member, a second driving member, and a push plate. The push plate is mounted on the driving end of the second driving member and is disposed toward the connector. The second driving member is mounted on the driving end of the first driving member and is capable of moving along the length direction of the first groove under the drive of the first driving member.

[0013] A liquid injection device includes a tray moving mechanism, a battery conveying mechanism, a pushing mechanism, and a liquid injection tray as described in any of the above embodiments. The liquid injection tray is installed on the moving end of the tray moving mechanism, and the inlet is disposed facing the width direction of the tray moving mechanism. The battery conveying mechanism is disposed on at least one side of the width direction of the tray moving mechanism.

[0014] In the aforementioned liquid injection tray and liquid injection feeding device, during battery feeding, the tray moving mechanism first moves the liquid injection tray until the inlet is aligned with the battery conveying mechanism; then, the stop member is moved out from the inlet range of the corresponding first groove to open the inlet; next, the pushing mechanism can push the batteries conveyed by the battery conveying mechanism sequentially from the inlet into the first groove, thereby quickly transferring the batteries from the battery conveying mechanism to the liquid injection tray. After the batteries are transferred, the stop member can be moved back into the inlet range of the corresponding first groove to confine the batteries within the first groove. It is evident that the aforementioned liquid injection tray and liquid injection feeding device eliminate the need to individually grasp batteries during the battery feeding process, significantly improving feeding efficiency.

[0015] In addition, a liquid injection device includes a liquid injection apparatus and a liquid injection feeding device as described in any of the above embodiments. Attached Figure Description

[0029] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0030] Please see Figure 1 This utility model provides a liquid injection feeding device 10 and a liquid injection tray 200. Furthermore, this utility model also provides a liquid injection device (not shown), which includes the liquid injection feeding device 10 and the liquid injection device (not shown).

[0031] The electrolyte feeding device 10 can feed the battery 20 to be injected into the lower part of the electrolyte feeding device, and the electrolyte feeding device can inject the electrolyte into the battery 20 below. The battery 20 can be a cylindrical battery, and is generally supported in a cup 30 (see...). Figure 2 ).

[0032] In one embodiment of the present invention, the liquid injection and feeding device 10 includes a tray moving mechanism 100, a liquid injection tray 200, a battery conveying mechanism 300, and a pushing mechanism 400.

[0033] The liquid injection tray 200 is mounted on the moving end of the tray moving mechanism 100, and the battery conveying mechanism 300 is disposed on at least one side of the tray moving mechanism 100 in the width direction. The tray moving mechanism 100 can drive the liquid injection tray 200 to move in a preset direction, where the width direction of the tray moving mechanism 100 refers to the direction perpendicular to the moving direction of the liquid injection tray 200. Driven by the tray moving mechanism 100, the liquid injection tray 200 can first pass through the battery conveying mechanism 300 and then pass through the liquid injection device. The battery conveying mechanism 300 is used to convey batteries 20. Specifically, the battery conveying mechanism 300 includes at least one conveying line, on which multiple batteries 20 are arranged and conveyed sequentially. When the liquid injection tray 200 passes through the battery conveying mechanism 300, the pushing mechanism 400 can push the batteries 20 conveyed by the battery conveying mechanism 300 onto the liquid injection tray 200, thereby transferring the batteries 20 onto the liquid injection tray 200. Next, the liquid injection tray 200 and the battery 20 on it will be driven by the tray moving mechanism 100 to the bottom of the liquid injection device, so that the liquid injection device can inject liquid into the battery 20.

[0034] Specifically, the tray moving mechanism 100 includes two opposing roller conveyors. The two sides of the liquid injection tray 200 are supported by the two roller conveyors and can move along the roller conveyors under the drive of the driving component. The pushing mechanism 400 generally includes a pushing drive assembly and a pushing plate. When pushing the battery 20, the pushing drive assembly can first drive the pushing plate to move to the end of the battery queue away from the liquid injection tray 200, and then drive the pushing plate to move towards the liquid injection tray 200, thereby pushing the battery 20 from the battery conveying mechanism 300 to the liquid injection tray 200.

[0035] Please see Figure 2 and Figure 3 In one embodiment of the present invention, the liquid injection tray 200 includes a tray body 210 and a switch assembly 220.

[0036] The tray body 210 is generally rectangular and can be formed from metal, possessing high mechanical strength. Multiple first grooves 211 are formed on the surface of the tray body 210, with at least one end of each groove 211 having an inlet (not shown in the figure). The first grooves 211 can be formed by stamping, milling, or other methods on the tray body 210, or by using partitions. Furthermore, the inlet is oriented towards the width direction of the tray moving mechanism 100, so when the liquid injection tray 200 passes through the battery conveying mechanism 300, the inlet will face the battery conveying mechanism 300. The first grooves 211 serve to accommodate the batteries 20, and the pushing mechanism 400 can push the batteries 20 on the battery conveying mechanism 300 sequentially into the first grooves 211 through the inlets.

[0037] Specifically, both ends of the first groove 211 are provided with inlets, so the battery 20 can be pushed into the first groove 211 from either side of the liquid injection tray 200, thus improving the flexibility of the liquid injection tray 20 in applicable scenarios. In this embodiment, the first groove 211 is strip-shaped, and multiple first grooves 211 are arranged side by side. In this way, the resistance encountered when the battery 20 is pushed into the first groove 211 is small, the pushing is smoother, and jamming is avoided. Of course, in other embodiments, the first groove 211 can also be set in an S-shape or other smoothly transitioned shapes.

[0038] Please refer to the following: Figure 5 and Figure 7 In this embodiment, a guide plate 230 is provided on at least one side of the first groove 211 in the width direction, and the guide plate 230 extends along the length direction of the first groove 211. The edge of the guide plate 230 in the width direction extends into the range of the first groove 211. The guide plate 230 can cooperate with the groove (not shown in the figure) on the side of the cup 30 that carries the battery 20, thereby guiding the cup 30 and the battery 20 to facilitate the smooth pushing of the battery 20 into the first groove 211.

[0039] Please refer to the following: Figure 2 , Figure 3 and Figure 4 In this embodiment, a second groove 212 is formed at the bottom of the first groove 211, and the second groove 212 extends along the length of the first groove 211. The second groove 212 serves to collect electrolyte. During the electrolyte injection process, any leaked or overflowing electrolyte can eventually flow into the second groove 212, thereby preventing the battery 20 or other components from being contaminated by the electrolyte.

[0040] The switch assembly 220 includes a stop member 221, which is disposed corresponding to the first groove 211. When both ends of the first groove 211 have inlets, each first groove 211 has a stop member 221 at both ends. The stop member 221 can be in the form of a block, baffle, or lever. The stop member 221 can block or open the inlet of the first groove 211. Furthermore, each stop member 221 is operably movable relative to the tray body 210 to move into or out of the inlet range of the corresponding first groove 211. When the stop member 221 is within the range of the inlet of the first groove 211, it blocks the inlet; and when the stop member 221 moves out of the range of the inlet of the first groove 211, it opens the inlet.

[0041] When loading the battery 20, the tray moving mechanism 100 first moves the liquid injection tray 200 until the inlet is aligned with the battery conveying mechanism 300; then, the stop member 221 is moved out of the inlet range of the corresponding first groove 211 to open the inlet; next, the pushing mechanism 400 can push the battery 20 conveyed on the battery conveying mechanism 300 sequentially into the first groove 211 from the inlet, thereby quickly transferring the battery 20 from the battery conveying mechanism 300 to the liquid injection tray 200. After the battery 20 is transferred, the stop member 221 can be moved back into the inlet range of the corresponding first groove 211 to confine the battery within the first groove 211.

[0042] As the tray moving mechanism 100 continues to move, it can move the liquid injection tray 200 and the battery 20 it carries to the bottom of the liquid injection device to complete the liquid injection process. It is evident that since it is not necessary to individually grasp each battery 20 during the feeding process, the feeding efficiency can be significantly improved.

[0043] Please refer to the following: Figure 5 , Figure 6 and Figure 7 In this embodiment, the switch assembly 220 further includes a connector 222, and the abutments 221 corresponding to the plurality of first grooves 211 are all connected to the connector 222. By operating the connector 222, the plurality of abutments 221 can be moved synchronously, thereby simultaneously switching the on / off state of the feed inlets of the plurality of first grooves 211. This helps to simplify the structure of the liquid injection tray 200.

[0044] Furthermore, in this embodiment, the connector 222 extends along the parallel direction of the plurality of first grooves 211 and is movable relative to the tray body 210 in the parallel direction.

[0045] The connector 222 can be a long, narrow rod or baffle, extending along the parallel direction of the multiple first grooves 211. When the connector 222 moves along this parallel direction, it can move the stop 221 into or out of the corresponding inlet of the first groove 211, thereby switching the opening and closing state of the inlet. Moreover, the connector 222 requires less space to move the stop 221, thus facilitating the arrangement of the liquid injection tray 200 in a confined space.

[0046] It should be noted that in other embodiments, the connector 222 can also drive the stop 221 to move relative to the tray body 210 by rotating around its own axis or other means, so as to switch the opening and closing state of the feed port.

[0047] Please refer to it again. Figure 2 and Figure 3 Specifically, in this embodiment, the injection tray 200 further includes a pushing component 240, which is disposed at one end of the connector 222 and can push the connector 222 to move in a parallel direction. The pushing component 240 pushes the connector 222 to move, thereby switching the on / off state of the inlet. The pushing component 240 can be driven by a cylinder, motor, or the like, facilitating automated control.

[0048] Furthermore, in this embodiment, the switch assembly 220 also includes an elastic element 223, which is connected to the tray body 210 along with the connector 222.

[0049] The elastic element 223 provides elastic force to the connector 222. When the pushing component 240 does not act on the connector 222, the connector 222 will be held within the inlet range by the stop element 221 under the action of the elastic element 223. That is to say, the inlet of the first groove 211 is normally closed.

[0050] When the pushing component 240 pushes the connector 222 to open the feed port, it needs to overcome the elastic force of the elastic element 223; when the force of the pushing component 240 is removed, the connector 222 can be reset under the action of the elastic element 223, so that the feed port of the first groove 211 returns to the closed state.

[0051] Specifically, the elastic element 223 includes a compression spring and a tension spring. The compression spring is located at the end of the connector 222 away from the pushing component 240, while the tension spring is located at the end of the connector 222 closer to the pushing component 240. After the force of the pushing component 240 is removed, both ends of the connector 222 will be subjected to tension and thrust respectively, thereby enabling the connector 222 to return to its original position smoothly and quickly.

[0052] Furthermore, in this embodiment, the pushing component 240 includes a first driving member 241, a second driving member 242, and a push plate 243. The push plate 243 is mounted on the driving end of the second driving member 242 and is positioned towards the connector 222. The second driving member 242 is mounted on the driving end of the first driving member 241 and can move along the length direction of the first groove 211 under the drive of the first driving member 241.

[0053] Specifically, both the first driving component 241 and the second driving component 242 can be cylinders. Before the battery 20 is fed in, the first driving component 241 can first drive the second driving component 242 and the push plate 243 to move towards the center of the tray body 210. In this way, interference between the pushing component 240 and the tray moving mechanism 100 can be prevented during the movement of the liquid injection tray 200 by the tray moving mechanism 100. When it is necessary to open the inlet, the first driving component 241 can drive the second driving component 242 and the push plate 243 to move towards the edge of the tray body 210 until the push plate 243 is aligned with the connector 222, and then the second driving component 242 drives the 243 to push the connector 222.

[0054] In the aforementioned liquid injection tray 200 and liquid injection feeding device 10, during battery 20 feeding, the tray moving mechanism 100 first moves the liquid injection tray 200 until the feeding port aligns with the battery conveying mechanism 300; then, the stop member 221 is moved out of the feeding port range corresponding to the first groove 211 to open the feeding port; next, the pushing mechanism 400 can push the batteries 20 conveyed by the battery conveying mechanism 300 sequentially into the first groove 211 from the feeding port, thereby quickly transferring the batteries 20 from the battery conveying mechanism 300 to the liquid injection tray 200. After the batteries 20 are transferred, the stop member 221 can be moved back into the feeding port range corresponding to the first groove 211 to confine the batteries within the first groove 211. Therefore, the aforementioned liquid injection tray 200 and liquid injection feeding device 10 do not need to individually grasp the batteries 20 during the battery 20 feeding process, which can significantly improve feeding efficiency.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
