[0003] With the mature development of automatic technology, therefore, the current battery manufacturer, when adding the electrolyte, in order to improve the injection efficiency, generally will be clamped in the corresponding clamping fixture in the electrolyte of multiple groups needing to be added, then through the arm drive injection head, and the automatic injection of multiple batteries is carried out.
[0004] In order to improve the efficiency of putting the battery into the clamping fixture, generally the fixture is in the horizontal opening and closing state, and then the battery is vertically put into the clamping fixture from the top by the machine arm.
[0005] However, due to the different models of the battery, the position of the battery filling port will also be different, at this time, in order to better fill some models of the battery, after the battery is put into the clamping fixture, the clamping fixture also needs to be adjusted at an angle of 45 degrees to ensure that the filling head can be inserted into the battery filling port, and after the filling is completed, the clamping fixture is restored to the initial state.

DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0031] In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
[0032] Embodiment:
[0033] Refer toFigures 1-7 The utility model provides a 45 degree turnover mechanism for battery liquid injection, including frame body 1, frame body 1 plays the support function, turnover platform 101 is rotatably connected on frame body 1, clamping fixture 7 is fixedly installed on turnover platform 101, and the number of clamping fixture 7 is generally 9-15.
[0034] Frame body 1 is fixedly connected with the block 4, when turnover platform 101 overturns 45 degrees, the bottom of turnover platform 101 and the block 4 mutually fit, and the upper surface of block 4 is inclined 45 degrees.
[0035] The spring 5 and first air cylinder 2 are located at both sides of turnover platform 101 respectively, and the spring 5 and block 4 are located at the same side.
[0036] When the battery is placed in clamping fixture 7, needs to overturn 45 degrees to clamping fixture 7, starts first air cylinder 2, drives turnover platform 101 to rotate, when the bottom of turnover platform 101 and block 4 mutually fit, first air cylinder 2 stops working, at this time, turnover platform 101 overturns 45 degrees, and then realizes that clamping fixture 7 overturns 45 degrees, and it is convenient to add electrolyte to the battery.
[0037] When turnover platform 101 overturns 45 degrees, through the tension of spring 5, it mutually fits with block 4, avoids that turnover platform 101 shakes, and then ensures that electrolyte is not easy to spill in the process of adding electrolyte, protects the damage of filling head, reduces the occurrence of production accident.
[0038] It needs to be explained that the reason why cylinder drives turnover platform 101 to overturn, instead of directly driving with motor, is because turnover platform 101 is installed with multiple groups of clamping fixture 7 to clamp the battery, so it is very heavy, and if directly driving with motor, the torque will be very big, and the motor is easy to be damaged, and the work is unstable.
[0039] As Figure 1 , Figure 3 , Figure 4 , Figure 6 Frame body 1 is further equipped with limiting mechanism, when turnover platform 101 is in the stationary state, the limiting of turnover platform 101 is carried out.
[0040] The so-called turnover platform 101 is in the stationary state, refers to the state of turnover platform 101 before and after overturning.
[0041] The limiting mechanism is designed in 4 groups, 2 groups are arranged on one side of the tension spring 5, and are used to limit the turnover table 101 after being turned over by 45°; 2 groups are arranged on one side of the first cylinder 2, and are used to limit the turnover table 101 before being turned over by 45°, or after being reset.
[0042] Each group of limiting mechanisms comprises a limiting plate 3 fixed on the bottom of the turnover table 101, an inclined block 304 slidingly connected to the frame body 1, and a second cylinder 305 fixedly connected to the frame body 1; the output end of the second cylinder 305 is connected to the inclined block 304; and the inclined block 304 can be attached to the limiting plate 3.
[0043] As Figure 6 , the turnover table 101 is turned over by 45°, at this time, the second cylinder 305 located on the same side of the tension spring 5 is started, the inclined block 304 is moved to the direction of the limiting plate 3, the inclined block 304 is directly inserted into the limiting plate 3 and attached to the inner wall of the limiting plate 3, so that the turnover table 101 is prevented from being accidentally rotated in the opposite direction due to insufficient tension of the tension spring 5 during the process of adding electrolyte.
[0044] When the addition of electrolyte is completed, the inclined block 304 is returned to release the limiting.
[0045] As Figure 3 and Figure 4 , when the addition of electrolyte is completed, the turnover table 101 is reset to take out the battery, that is, the turnover table 101 needs to be turned clockwise by 45°, at this time, the second cylinder 305 located on the same side of the first cylinder 2 can be started to drive the corresponding inclined block 304 to be attached to the limiting plate 3 on the same side, so as to limit the turnover table 101 from being rotated counterclockwise under the tension of the tension spring 5.
[0046] As Figure 4 and Figure 6 , the frame body 1 is fixedly connected with a guide rail 302, the guide rail 302 is designed in 2 groups, the guide rail 302 is slidingly connected with a sliding table 303, the sliding table 303 can only slide on the guide rail 302 and cannot be separated; the inclined block 304 is fixedly connected to the sliding table 303; and the output end of the second cylinder 305 is fixedly connected to the sliding table 303.
[0047] Through the design of the sliding table 303 and the guide rail 302, the inclined block 304 moves more stably.
[0048] As Figure 4 and Figure 6 , the limiting plate 3 is rotationally connected with a limiting shaft 301.
[0049] When limiting, the inclined block 304 is attached to the limiting shaft 301 on the limiting plate 3, and through the rotational connection of the limiting shaft 301, the mutual friction between parts can be reduced.
[0050] As Figure 1 And Figure 2 The output end of the first cylinder 2 is fixedly connected with a push plate 201, and the push plate 201 is rotationally connected with a roller shaft 202; the bottom of the turnover table 101 is fixedly connected with a clamping plate 203, and the roller shaft 202 is clamped in the clamping plate 203.
[0051] The clamping plate 203 is provided with a through slot in the middle, and the roller shaft 202 is clamped in the through slot.
[0052] When the first cylinder 2 drives the turnover table 101 to turn over, the first cylinder 2 pushes the push plate 201 to move upwards, and the roller shaft 202 slides in the through slot in the clamping plate 203 while moving upwards, thereby realizing the driving of the turnover table 101 to turn over.
[0053] The roller shaft 202 and the clamping plate 203 are both designed in two groups; through the design of two groups, the stress is uniform, and the turnover table 101 is pushed to turn over more stably.
[0054] As Figure 3 The push plate 201 can penetrate the notch 6.
[0055] When the turnover table 101 at 45° is reset, at this time, the first cylinder 2 drives the push plate 201 to move downwards, and the push plate 201 penetrates the notch 6, avoiding interference with the frame 1.
[0056] As Figure 7 The fitting block 4 is threadedly connected with an adjusting screw 401.
[0057] The adjusting screw 401 can penetrate the upper surface of the fitting block 4.
[0058] When working for a long time, when the turnover table 101 turns over and the fitting block 4 is fitted, because of the friction factor, if the turnover table 101 turns over more than 45°, at this time, the adjusting screw 401 is rotated, and the fitting block 4 is extended upwards, and is adjusted, so that when the turnover table 101 is fitted with the end of the adjusting screw 401, the turnover table 101 is 45°, ensuring the turning precision.
[0059] The fitting block 4 is also designed in two groups, and both are located on the same side of the tension spring 5.
[0060] The tension spring 5 is designed in two groups, and the two groups of tension springs 5 are symmetrically designed and are both located on the side of the turnover table 101 away from the first cylinder 2.
[0061] Through the design of the two groups of tension springs 5, the turnover table 101 can be simultaneously pulled and stressed uniformly, improving the stability of long-time work.
[0062] As Figure 5 And Figure 6The fixing base 102 is fixed on the overturning table 101.
[0063] Each clamping jig 7 is fixed on the corresponding fixing base 102, so the number of the clamping jigs 7 is same as the number of the fixing bases 102.
[0064] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
