[0029] like Figure 1 As shown, an embodiment of the present application provides a positioning device 100 for a liquid injection tube 210, including a mounting plate 110, a positioning member 120, a movable component and a detection mechanism.

[0030] The positioning member 120, the movable assembly and the detection mechanism are all arranged on the mounting plate 110. The positioning member 120 is used to position the injection tube 210 so as to fix the injection tube 210 at the positioning device. The movable assembly includes a movable block 131 and a reset member 132. The movable block 131 can reciprocate between the initial position and the in-position position. The reset member 132 is connected to the movable block 131 and is used to provide a force to move the movable block 131 toward the initial position. The injection tube 210 positioned on the positioning member 120 can push the movable block 131 to the in-position position. The detection mechanism can detect the position of the movable block 131.

[0031] By using the above positioning device, the mounting plate 110 is installed on the electrolyte production line. After the injection tube 210 is filled with liquid, the injection tube 210 is inserted into the positioning member 120 for positioning. During the insertion process of the injection tube 210, the movable block 131 can be pushed to the right position. When the detection mechanism detects that the movable block 131 has moved to the right position, it means that the injection tube 210 has returned to its position correctly, and the automatic guided vehicle can start to move. In this way, the automatic guided vehicle can avoid accidentally pulling or hitting the injection tube 210, thereby avoiding the risk of damage to the injection tube 210 or leakage of electrolyte and other media.

[0032] It should be noted that the injection pipe 210 completes the injection, and the injection can be injecting electrolyte into the ton barrel, or injecting cleaning liquid into the ton barrel, which is not limited here.

[0033] In one embodiment, the positioning device further includes a bracket, which is installed on a corresponding station on the electrolyte production line, and the mounting plate 110 is installed on the bracket. In practical applications, according to the requirements of the production line, the bracket can be set as a first bracket 141 and a second bracket 142. Figure 1 In the embodiment shown, the injection tube 210 is placed in a vertical position, and the mounting plate 110 is arranged on the top of the first bracket 141. Figure 2 In the illustrated embodiment, the injection tube 210 is placed in a horizontal state, and the mounting plate 1110 is disposed on the side of the second bracket 142 .

[0034] Please continue reading Figure 2 The positioning device further includes a balancer 150, which is connected between the second bracket 142 and the injection tube 210 to prevent the position of the injection tube 210 from being offset. Specifically, the injection tube 210 is connected to other structures through an extension tube 220, and the balancer 150 and the injection tube 210 are located on opposite sides of the second bracket 142, and the balancer 150 is connected to the extension tube 220 extending into the second bracket 142 away from the injection tube 210, so as to pull the extension tube 220 to prevent the injection tube 210 from moving relative to the positioning member 120.

[0035] In one embodiment, the positioning member 120 includes a bearing portion and a positioning portion, the bearing portion is connected to the mounting plate 110, the bearing portion can bear the injection tube 210, the positioning portion is connected to the side of the bearing portion away from the mounting plate 110, and the positioning portion is for the injection tube 210 to be inserted, so as to position the inserted injection tube 210. In practical applications, the positioning member 120 is a positioning joint, the positioning joint matches the injection tube 210, the injection tube 210 is inserted into the positioning joint, and the movable block 131 can be pushed to the right position during the insertion of the injection tube 210 into the positioning joint.

[0036] In one embodiment, the bearing portion and the movable block 131 are located on the same side of the mounting plate 110, and when the movable block 131 moves to the in-place position, the surface of the bearing portion facing away from the mounting plate 110 is flush with the surface of the movable block 131 facing away from the mounting plate 110. It can be seen that the injection tube 210 is inserted into the positioning portion and carried by the bearing portion, and at the same time, the movable block 131 is pushed to the in-place position.

[0037] In one embodiment, the movable assembly further includes a guide rod 133, the guide rod 133 is fixedly connected to the mounting plate 110, the movable block 131 is reciprocatably connected to the guide rod 133, and the movable block 131 can move closer to and away from the mounting plate 110 during the reciprocating movement. Specifically, the movable block 131 is sleeved on the guide rod 133 so that the movable block 131 can move reciprocatingly along the guide rod 133. It can be understood that the movable block 131 can move to a position in the process of moving closer to the mounting plate 110, and the reset member 132 can push the movable block 131 away from the mounting plate 110, so that the movable block 131 moves to the initial position.

[0038] In one embodiment, the movable assembly includes a plurality of guide rods 133 and a plurality of reset members 132. The plurality of guide rods 133 can improve the stability of the movement of the movable block 131. Each reset member 132 is sleeved on the outer side of a corresponding guide rod 133, and the two ends of the reset member 132 are respectively in contact with the mounting plate 110 and the movable block 131 to push the movable block 131 away from the mounting plate 110. Specifically, the reset member 132 is a spring.

[0039] In one embodiment, the detection mechanism includes a detector 160 and a communication module. The detector 160 is disposed on the mounting plate 110 and is capable of detecting the position of the movable block 131. The communication module is electrically connected to the detector 160 to send the detection data of the detector 160 to an external device, such as a control system of an electrolyte production line, so as to control the action of the automatic guided vehicle according to the detection data of the detector 160. Specifically, when the detector 160 does not detect that the movable block 131 has moved to the in-place position, it means that the injection tube 210 has not returned to its position, and the control system controls the automatic guided vehicle to remain stationary; when the detector 160 detects that the movable block 131 has moved to the in-place position, it means that the injection tube 210 has been inserted into the positioning member 120 and the injection tube 210 has returned to its position, and the control system controls the automatic guided vehicle to perform the handling task. In practical applications, the detector 160 is a proximity sensor.

[0040] Based on the above-mentioned positioning device for the liquid injection tube 210, the present application also provides an electrolyte production line, which includes the liquid injection tube 210 and the positioning device in the above-mentioned embodiment.

[0041] In one embodiment, the electrolyte production line also includes a manipulator, which is detachably connected to the injection tube 210. When an injection task needs to be performed, the manipulator is connected to the injection tube 210, and then the injection is performed through the injection tube 210. After the injection is completed, the manipulator inserts the injection tube 210 into the positioning piece 120, so that the injection tube 210 returns to its position.

[0042] In one embodiment, the electrolyte production line further includes a ton barrel and an automatic guided vehicle. The ton barrel is used to store electrolyte. The injection pipe 210 can inject electrolyte or cleaning liquid into the ton barrel. The cleaning liquid is used to clean the ton barrel. The automatic guided vehicle can transport the ton barrel.

[0043] Specifically, before the control system issues a handling task to the automatic guided vehicle, it needs to first obtain the detection result of the detector 160 sent by the communication module. If the detector 160 detects that the movable block 131 has moved to the in-place position, that is, the injection tube 210 has returned to its position, the handling task is issued and the automatic guided vehicle starts to carry the ton barrel; if the detector 160 does not detect the movable block 131 that has moved to its in-place position, it means that the injection tube 210 has not returned to its position, and the issuance of the handling task is suspended at this time. In addition, if the detector 160 does not detect that the injection tube 210 has returned to its position during the process of the automatic guided vehicle carrying the ton barrel, the control system controls the automatic guided vehicle to stop the handling action and sound an alarm.

[0044] The positioning device for the injection tube 210 and the electrolyte production line provided in the present application have at least the following advantages:

[0045] The injection tube 210 is positioned by the positioning member 120, and the positioned injection tube 210 can push the movable block 131 to the designated position, so that the return status of the injection tube 210 can be obtained through the position of the movable block 131, ensuring that the movement of the automatic guided vehicle is controlled when the injection tube 210 returns, thereby ensuring the safety of operation.

[0046] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
