[0040] The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and should not be construed as limiting the utility model.

[0041] In order to solve the problems raised in the background art, the utility model proposes the following solutions.

[0042] Embodiment 1

[0043] Please refer to Figure 1, in this embodiment, a feeding and positioning device is proposed. This feeding and positioning device is used for a battery grading machine, so that when the battery grading machine is in the upper position, the feeding and positioning device is beneficial to ensure accurate positioning of the battery during feeding.

[0044] Specifically, the feeding and positioning device includes a limiting member 1 and a placement platform 2. The limiting member 1 is used to limit the battery. The limiting member 1 can limit the battery 3 from the peripheral side of the battery to restrict the movement of the battery along the first direction or the second direction on the placement platform 2 of the battery grading machine.

[0045] The limiting member 1 is formed on the placement platform 2 of the battery grading machine. During implementation, the limiting member 1 can be integrally formed with the placement platform 2, or can be fixed on the placement platform 2 by means of bolted connection, clamping or bonding. In some implementation manners, the limiting member 1 can also be slidably arranged on the placement platform 2 and fixed at a specified position through a locking structure. In this way, the position of the limiting member 1 can be adjusted as needed, and it can be applicable to batteries 3 with different sizes and position requirements.

[0046] During specific implementation, the limiting member 1 is used to restrict the movement of the battery 3 in the first direction and the second direction; the first direction intersects with the second direction, and both are parallel to the placement platform 2. That is, the first direction and the second direction are directions in the plane where the placement platform 2 is located, and the movement of the battery 3 on the placement platform 2 can be restricted through the limiting member 1.

[0047] It should be noted that restricting the movement of the battery 3 in the first direction and the second direction does not mean that it cannot move in the first direction and the second direction. Instead, when the battery 3 moves in the direction approaching the limiting member 1 along the first direction, after abutting against the limiting member 1, it cannot continue to move forward. When the battery moves in the direction approaching the limiting member 1 along the second direction, after abutting against the limiting member 1, it cannot continue to move forward.

[0048] Due to the setting of the limiting member 1, during feeding, the battery 3 can be directly abutted against the limiting member 1. In this way, the battery 3 can be quickly and accurately placed in the corresponding position in the required posture. It can avoid problems caused by inaccurate manual feeding and positioning, which is beneficial to improving the feeding efficiency of the grading process.

[0049] In a specific implementation, the limiting member 1 includes a first limiting bar 11 and a second limiting bar 12; that is, the limiting is performed by the first limiting bar 11 and the second limiting bar 12. In some implementations, at least two positioning rods located on the same straight line can also be used to replace the first limiting bar 11 and / or the second limiting bar 12. In some implementations, the number of the first limiting bar 11 and the second limiting bar 12 can be 1 each. When placing the battery, the first limiting bar 11 and the second limiting bar 12 are used to limit the two sides of the battery. When the two sides of the battery 3 are respectively in contact with the first limiting bar 11 and the second limiting bar 12, the battery 3 is placed in place.

[0050] Although the use of a first limiting strip 11 and a second limiting strip 12 can limit the position of the battery 3, which is beneficial to improving the loading efficiency and reducing the requirements for operators; there is still a situation where the battery 3 is offset during the pressing process after the loading is placed in place. For this reason, this embodiment has been further improved: please refer to Figure 3 , the first limit strip 11 is used to limit the movement of the battery 3 in the first direction from one side; the number of the second limit strips 12 is two and they are arranged in parallel, and the two second limit strips 12 are used to limit the movement of the battery 3 in the second direction from two parallel sides. Wherein, the first direction and the second direction correspond to two different directions of the battery respectively, such as the first direction intersecting with the second direction, that is, the angle between the first direction and the second direction is greater than 0 degrees and less than 180 degrees. For the square battery 3, the first direction is perpendicular to the second direction. That is, the battery 3 is limited from the circumferential side by a first limit strip 11 and two second limit strips 12, and only the side corresponding to the battery 3 provided with the pole ear 31 is left unlimited, so as to facilitate the removal and placement of the battery 3 from this side.

[0051] Please refer to Figure 3 In the specific implementation, in order to ensure the accuracy of the limit and limit the direction perpendicular to the placement platform 2, the first limit strip 11 has a shape that matches the side of the battery 3 away from the pole ear 31; the second limit strip 12 has a shape that matches the corresponding side of the battery 3. In some implementations, in the circumferential direction of the battery 3, except for the side with the pole ear, other sides are provided with convex strips protruding outward. In this case, the first limit strip 11 is provided with a first avoidance groove, and the second limit strip 12 is provided with a second avoidance groove; the first avoidance groove and the second avoidance groove are respectively adapted to the convex strips on the corresponding sides.

[0052] In a specific implementation, in order to facilitate pressing the battery 3 on the placement platform, the dimension of the stopper 1 in the third direction is not greater than the dimension of the battery 3 in the third direction; the third direction is perpendicular to the placement platform 2 and corresponds to the thickness direction of the battery. In this way, it is convenient to press the pressing plate onto the battery 3 to provide the battery 3 with corresponding pressure.

[0053] Example Two

[0054] This embodiment is a specific application of Embodiment One. The same parts will not be described again. Only the differences will be described below.

[0055] After the existing grading equipment places the battery on the platform, there is no large-surface fixing mechanism. It is necessary to manually add a heavy object on the large surface of the battery to press the large surface of the battery to prevent the battery from bulging during the grading process. When manually placing the heavy object, the position may be offset, causing local pressure on the large surface of the battery, resulting in uneven pressure on the large surface of the battery, with indentations or bulging of the unpressed part. The pressure of the placed heavy object cannot be adjusted arbitrarily, which is not convenient for grading under different pressures. Therefore, the following improvements are made in this embodiment.

[0056] Please refer to Figures 2 to 5 , this embodiment proposes a battery grading machine, which includes a frame 4, a placement platform 2, a pressing plate 5, and the feeding and positioning device described in Embodiment One. Among them, the frame 4 is used to support the entire structure, the placement platform 2 is used to place the battery 3 to be graded, and the pressing plate 5 is used to provide pressure to the battery 3 to be graded placed on the placement platform 2.

[0057] Specifically, the placement platform 2 is formed on the frame 4; the placement platform 2 can be integrally formed with the frame 4, or can be fixed to the frame 4 by bolts, or can also be fixed to the frame 4 by means such as bonding, welding or clamping. In specific implementation, the pressing plate 5 is slidably arranged on the frame 4 in a direction close to or away from the placement platform 2; the pressing plate 5 is used to provide pressure to the battery 3 on the placement platform 2. In a preferred implementation manner, the pressing plate 5 is located above the placement platform 2.

[0058] In specific implementation, in order to ensure that the pressure received by the battery 3 is controllable, in this embodiment, a driving device 6 is further included. The driving device can be a telescopic member or a structure with a reciprocating linear movement characteristic. For example, it can be a hydraulic cylinder or a pneumatic cylinder. In a preferred implementation manner, the driving device 6 is an electric cylinder. One end of the electric cylinder is connected to the frame 4, and the other end is connected to the pressing plate 5. When in use, the pressure is adjusted by controlling the telescopic length of the electric cylinder. In specific implementation, in order to further improve the control accuracy of the pressure, a pressure sensor can also be set on the pressing plate 5 or the placement platform 2 to facilitate intuitively and accurately adjusting the pressure of the pressing plate 5.

[0059] In the current technology, the environmental control during the grading process is relatively high, and heat is also generated during the battery grading process, making it impossible to ensure that the grading process is carried out at a constant temperature. Therefore, the following improvements are also made in this embodiment: Please refer to Figure 2 and Figure 3, the placement platform 2 and / or the press plate 5 are provided with a cooling channel and an inlet and an outlet connected to the cooling channel. That is, in some implementations, the cooling channel can be set only in the press plate 5, and in other implementations, the cooling channel can be set only in the placement platform 2; preferably, in order to ensure a good heat dissipation effect, the cooling channel can be set in both the press plate 5 and the placement platform 2. In a specific implementation, in order to facilitate the formation of the cooling channel in the press plate 5, the press plate 5 can be set as a split structure; in order to facilitate the formation of the cooling channel in the placement platform 2, the press plate 5 can be set as a split structure. In a specific implementation, the cooling liquid channel can be bent and arranged in the press plate 5 or the placement platform 2. In order to achieve a better cooling effect, multiple cooling channels can be connected in parallel. In a specific implementation, the cooling channel is used to pass the coolant, and of course, in some cases, the heat can also be dissipated by gas.

[0060] Please refer to Figures 3 to 5 In specific implementation, the positioning device for loading and positioning proposed in Example 1 can realize the positioning of the battery 3. After the battery 3 is placed in place, the pole lug 31 of the battery 3 is located on the side away from the first limiting strip 11. When dividing the capacity, the pole lug 31 needs to be electrically connected to the test circuit. In order to achieve the electrical connection between the pole lug 31 and the test circuit, the following improvements are made in this embodiment. The battery capacity dividing machine proposed in this embodiment also includes a pole lug connection assembly 7 for connecting the pole lug 31, and the pole lug connection assembly 7 includes a support frame 71 and a test pressure claw 72. The support frame 71 is used to support the test pressure claw 72, and the test pressure claw 72 is used to contact the corresponding pole lug 31 to achieve electrical connection. The pressing plate 5 is provided with a pressing piece 51 corresponding to the test pressure claw 72, and the pressing piece 51 can be pressed on the test pressure claw 72 so that the test pressure claw 72 is electrically connected to the pole lug 31 of the battery 3.

[0061] In a specific implementation, the test pressure claw 72 can be an elastic conductive sheet. When the pressure plate 5 moves downward, it drives the pressure piece 51 to move downward. The pressure piece 51 presses the test pressure claw 72 downward to make the test pressure claw contact with the corresponding pole ear 31 to achieve electrical connection between the test pressure claw and the pole ear 31.

[0062] In some implementations, in order to ensure the reliability of conductivity, the test clamp 72 may include two mutually hinged parts to form a clamp-like structure. By pressing down the test clamp 72, the test clamp 72 clamps the corresponding pole ear 31 from both sides to ensure good conductivity during the capacitance division process.

[0063] In a specific implementation, if the tab connection assembly 7 is fixedly arranged, the battery 3 will interfere with the tab connection assembly 7 during the process of taking and placing. In order to prevent the battery 3 from interfering with the tab connection assembly 7 during the process of taking and placing, in this embodiment, a telescopic member 8 is also included, one end of which is fixedly connected to the frame 4, and the other end is fixedly connected to the support frame 71. The telescopic member 8 can drive the support frame 71 to move in a direction close to or away from the limit member 1. In a specific implementation, the telescopic member 8 can be a cylinder, a hydraulic cylinder or an electric cylinder, among which a cylinder is preferred. When loading is required, the support frame 71 is controlled by the telescopic member 8 to move away from the limit member 1 to ensure sufficient space for the battery 3 to be inserted between the two second limit strips 12 until the battery rests on the first limit strip 11. After the battery is placed in place, the support frame 71 is controlled by the telescopic member 8 to approach the limit member 1, specifically, the test pressure claw 72 is moved to a position close to the corresponding tab 31.

[0064] In the specific implementation, in order to facilitate the installation of the test pressing claw 72, the tab connection assembly 7 further includes a locking bolt 73 and a mounting frame 74. Specifically, the support frame 71 is provided with a slide groove 75, and the length direction of the slide groove 75 is arranged parallel to the first limit bar 11.

[0065] The mounting frame 74 is slidably disposed in the slide slot 75; a strip-shaped hole 76 is formed on the wall of the slide slot 75; the mounting frame 74 is slidably disposed in the slide slot 75, so that the position of the mounting frame 74 can be easily adjusted, so that the test pressing claw 72 installed on the mounting frame 74 moves close to the top of the corresponding pole lug 31. In a specific implementation, since the number of pole lugs 31 is two, the number of the mounting frame 74 and the test pressing claw 72 is also two.

[0066] The locking bolt 73 passes through the strip hole 76 and is connected to the mounting frame 74; in a specific implementation, the adjustment between the two test pressing claws 72 is achieved by adjusting the position of the mounting frame 74. One end of the test pressing claw 72 is installed in the mounting frame 74, and the other end faces the limiter 1. In a specific implementation, when the test pressing claw 72 is an elastic conductive sheet, one end of the test pressing claw 72 is fixed in the mounting frame 74, and the other end is a free end, and the free end is in a natural state, when close to the corresponding pole ear, it is located directly above the pole ear 31, and the test pressing claw 72 is contacted with the pole ear 31 by pressing down the pressing member 51. When the test pressing claw 72 is a clamp formed by hingedly connecting two clamping members, the clamping mouth of the clamp faces the corresponding pole ear 31, and when the test pressing claw 72 is in a position close to the corresponding pole ear 31, the pole ear 31 is located in the clamping mouth, and the test pressing claw 72 is pressed down by the pressing member 51 to press the corresponding test pressing claw 72 so that the corresponding test pressing claw 72 is electrically connected to the corresponding pole ear 31.

[0067] In some implementations, the pressing member 51 is a plate member located at the edge of the pressing plate 5. Specifically, the pressing member 51 is an L-shaped plate. The connection between the pressing member 51 and the pressing plate 5 can be integrally formed, welded or bolted. A pressing groove is provided at the end of the pressing member 51, and the pressing groove is adapted to the test pressing jaw 72 to prevent the pressing member 51 from detaching from the test pressing jaw 72 during the downward pressing process.

[0068] During use, place the battery 3 to be capacity-tested on the placement platform 2 and make the battery 3 fit against the limiting member 1. At the same time, ensure that the side of the battery 3 with the tab 31 faces the tab connection assembly 7. Start the telescopic member 8, and drive the tab connection assembly 7 to move closer to the tab 31 of the battery 3 through the telescopic member 8. Start the electric cylinder to drive the pressing plate 5 to press the large surface of the battery 3 and apply pressure to the battery 3 according to the set pressure. As the pressing plate 5 moves downward, the pressing member 51 moves downward and abuts against the test pressing jaw 72. The test pressing jaw 72 is pressed tightly against the tab 31 under the pressure of the pressing member 51 to ensure normal circuit connection. Start the external chiller to cool the placement platform 2 and the pressing plate 5 to keep the temperature relatively constant during operation.

[0069] Through the above-mentioned first embodiment and second embodiment, by using the loading and positioning device, the difficulty of the loading operation can be reduced, which is beneficial to avoiding the situation of the battery 3 being placed offset, accelerating the loading speed and placement accuracy of the battery 3, and improving the production efficiency.

[0070] By pressing and fixing the battery 3 with the pressing plate 5, the pressure can be adjusted according to needs, which can prevent the battery 3 from bulging during capacity testing. By arranging cooling channels in the placement platform 2 and the pressing plate 5, coolant can be introduced into the cooling channels to cool the equipment and ensure a constant temperature during the capacity testing process.

[0071] It should be noted that the first direction is parallel to Figure 1 the direction of the x-axis in Figure 1 the second direction is parallel to Figure 1 the direction of the y-axis in
