These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0045] Existing sorting equipment can only measure the thickness of batteries, and requires manual folding of the aluminum-plastic film of the batteries, or the batteries need to be transferred to other equipment for folding the aluminum-plastic film, which greatly increases the number of times the batteries are circulated in the logistics, makes the operation cumbersome, and reduces work efficiency.

[0046] In order to solve the above problems, Figures 1 to 3As shown, this embodiment provides a battery sorting device, which includes a carrying platform 1, a testing mechanism 2 and a folding mechanism 3, wherein the carrying platform 1 is used to carry the battery 20 to be sorted, the testing mechanism 2 includes a thickness measuring plate 21, a thickness measuring drive 22 and a displacement detection member (not shown in the figure), the output end of the thickness measuring drive 22 is transmission-connected to the thickness measuring plate 21, the thickness measuring drive 22 is used to drive the thickness measuring plate 21 to move so that the thickness measuring plate 21 switches between a clamping position for clamping the battery 20 and an avoidance position away from the battery 20, the displacement detection member is used to detect the distance the thickness measuring plate 21 moves from the avoidance position to the clamping position, the folding mechanism 3 is located on the outside of the carrying platform 1 and the thickness measuring plate 21, the folding mechanism 3 includes a folding drive 31 and a folding assembly 32, the output end of the folding drive 31 is transmission-connected to the folding assembly 32, the folding drive 31 is used to drive the folding assembly 32 to press against the edge of the packaging of the battery 20. The battery sorting device provided in this embodiment measures the thickness of the battery 20 by setting a testing mechanism 2, and realizes the folding operation on the edge of the packaging of the battery 20 by setting a folding mechanism 3, so that the battery sorting device can not only measure the thickness of the battery 20, but also perform the folding operation on the edge of the packaging of the battery 20, making the battery sorting device more comprehensive in function. There is no need to set up multiple devices separately to measure the thickness and fold the battery 20, which reduces the number of times the battery 20 is circulated in the logistics, makes the thickness measurement and folding operations of the battery 20 more consistent, and improves work efficiency.

[0047] Optionally, in this embodiment, the packaging object refers to the aluminum-plastic film 201, the folding mechanism 3 performs the folding operation on the edge of the aluminum-plastic film 201 of the battery 20, and the folding component 32 is opposite to the aluminum-plastic film 201 extending out of the supporting platform 1 of the battery 20.

[0048] Optionally, in this embodiment, the displacement detecting member is a displacement sensor, which is mounted on the thickness measuring platen 21. It should be noted that the distance from the avoidance position of the thickness measuring platen 21 to the support platform 1 is a constant value h1, and the distance the thickness measuring platen 21 moves from the avoidance position to the pressing position detected by the displacement sensor is h2. The difference between h1 and h2 is the thickness of the battery 20.

[0049] Optionally, in this embodiment, the thickness measuring drive member 22 and the folding drive member 31 may both be drive cylinders, which have the advantages of being reliable in operation and easy to install.

[0050] Optionally, in this embodiment, if Figure 2 and Figure 3As shown, a pressing protrusion 211 is provided on the side of the thickness measuring plate 21 facing the aluminum-plastic film 201 (i.e., the lower side of the thickness measuring plate 21). The folding assembly 32 is located on the outer side of the pressing protrusion 211. The pressing protrusion 211 can press the aluminum-plastic film 201 against the carrier 1. By providing the pressing protrusion 211 on the thickness measuring plate 21, when the thickness measuring plate 21 is in the pressing position for pressing the battery 20, the pressing protrusion 211 just presses the aluminum-plastic film 201 against the carrier 1, thereby achieving the positioning and pressing of the aluminum-plastic film 201, and making it easier for the folding assembly 32 to fold the edge of the aluminum-plastic film 201.

[0051] Optionally, in this embodiment, if Figure 2 and Figure 3 As shown, the testing mechanism 2 also includes a test probe 23, which is installed on the thickness measuring plate 21. When the thickness measuring plate 21 is in the clamping position, the test probe 23 is in contact with the tab 202 of the battery 20. By setting the test probe 23, the testing mechanism 2 can measure the voltage and internal resistance of the battery 20 through the test probe 23 while measuring the thickness of the battery 20. There is no need to use other equipment to measure the voltage and internal resistance of the battery 20, which further improves the efficiency of detecting and sorting the battery 20. It should be noted that two test probes 23 are arranged at intervals on the thickness measuring plate 21, one of which is in contact with the positive tab of the battery 20, and the other is in contact with the negative tab of the battery 20. Both test probes 23 are externally connected to a voltage and internal resistance tester, thereby realizing the detection of the voltage and internal resistance of the battery 20.

[0052] In this embodiment, if Figures 1 to 3 As shown, the hemming assembly 32 includes a hemming mounting frame 321 and a hemming roller 322, wherein the hemming mounting frame 321 is transmission-connected to the output end of the hemming drive member 31, and the hemming roller 322 is rotationally connected to the hemming mounting frame 321, and the hemming roller 322 can roll and abut against the edge of the aluminum-plastic film 201. By setting the hemming roller 322 to roll and abut against the edge of the aluminum-plastic film 201, the hemming operation of the aluminum-plastic film 201 is achieved by the hemming roller 322, which not only ensures the reliability of the hemming operation but also avoids damage to the aluminum-plastic film 201. Optionally, in this embodiment, the hemming assembly 32 is located above the carrier 1 and the battery 20, and the hemming roller 322 can bend the aluminum-plastic film 201 extending outward from the carrier 1 downward by 90°.

[0053] Optionally, in this embodiment, if Figures 1 to 3As shown, the aluminum-plastic films 201 on both sides of the battery 20 in the left-right direction both extend outward from the carrier platform 1 and both need to be folded. In order to ensure that the battery sorting equipment performs the folding operation on the aluminum-plastic films 201 on both sides of the battery 20, the battery sorting equipment provided in this embodiment includes two folding mechanisms 3, which are arranged at intervals along the left-right direction. The folding roller 322 of the folding mechanism 3 at the left end is directly opposite to the aluminum-plastic film 201 extending outward from the carrier platform 1 on the left side of the battery 20 in the vertical direction, and the folding roller 322 of the folding mechanism 3 at the right end is directly opposite to the aluminum-plastic film 201 extending outward from the carrier platform 1 on the right side of the battery 20 in the vertical direction, and the axis of each folding roller 322 extends in the front-to-back direction.

[0054] Optionally, in this embodiment, if Figures 1 to 3 As shown, the battery sorting equipment also includes a mounting mechanism 4 and a transfer drive mechanism 5, wherein the mounting mechanism 4 includes a connected mounting base 41 and a mounting bracket 42, and the mounting bracket 42 is mounted with a thickness measuring drive 22 and a folding drive 31. The transfer drive mechanism 5 is mounted on the mounting base 41. The transfer drive mechanism 5 is used to drive the carrier 1 to move between the loading and unloading station and the testing station. When the carrier 1 is located at the testing station, the battery 20 carried by the carrier 1 is located below the testing mechanism 2 and the folding mechanism 3. After the battery 20 carried by the carrier 1 completes the inspection and folding operation at the testing station, the transfer drive mechanism 5 drives the carrier 1 from the testing station to the loading and unloading station, thereby facilitating the handling equipment to carry the battery 20 that has completed the test and folding from the carrier 1. Then, the handling equipment carries the next battery 20 that needs to be tested and folded to the carrier 1 at the loading and unloading station. The transfer drive mechanism 5 again drives the carrier 1 from the loading and unloading station to the testing station to perform the testing and folding operation on the next battery 20.

[0055] In this embodiment, the transfer drive mechanism 5 includes a drive motor 51 and a screw rod 52. The drive motor 51 is mounted on the mounting base 41. The screw rod 52 extends along the moving direction of the support platform 1 (the front-to-back direction in the figure). The screw rod 52 is transmission-connected to the output end of the drive motor 51, and the screw rod 52 is threadedly connected to the support platform 1. The drive motor 51 rotates by driving the screw rod 52, so that the support platform 1 moves along the screw rod 52 between the loading and unloading station and the testing station. By designing the transfer drive mechanism 5 in the form of a drive motor 51 and a screw rod 52, the reliability and accuracy of the drive to the support platform 1 are guaranteed.

[0056] Optionally, in this embodiment, if Figures 1 to 3As shown, the battery sorting equipment also includes a guide mechanism 6, which includes a guide rail 61 and a sliding member 62 that are slidably connected. The guide rail 61 extends along the moving direction of the carrier platform 1. One of the guide rail 61 and the sliding member 62 is arranged on the mounting base 41, and the other of the two is arranged on the carrier platform 1. By providing the guide mechanism 6, a guide is provided for the reciprocating movement of the carrier platform 1 in the front-to-back direction, thereby ensuring the smoothness and reliability of the movement of the carrier platform 1. Optionally, in this embodiment, the guide rail 61 is arranged on the mounting base 41, and the sliding member 62 is arranged on the carrier platform 1. Optionally, in this embodiment, the sliding member 62 is a slide groove arranged on the carrier platform 1. In other embodiments, the guide rail 61 can also be arranged on the carrier platform 1, and the sliding member 62 can be arranged on the mounting base 41. In other embodiments, the sliding member 62 can also be arranged in the form of a slider.

[0057] In this embodiment, if Figures 1 to 3 As shown, the battery sorting equipment also includes a pressure-maintaining mechanism 7, which is located outside the support platform 1 and the thickness measuring plate 21. The pressure-maintaining mechanism 7 includes a pressure-maintaining driver 71 and a pressure-maintaining assembly 72, wherein the pressure-maintaining driver 71 is mounted on the mounting base 41, and the pressure-maintaining assembly 72 is transmission-connected to the output end of the pressure-maintaining driver 71. The pressure-maintaining driver 71 is used to drive the pressure-maintaining assembly 72 to abut against the edge of the bent aluminum-plastic film 201. Because the aluminum-plastic film 201 has a certain degree of flexibility, by providing the pressure-maintaining mechanism 7 and making the pressure-maintaining assembly 72 abut against the edge of the bent aluminum-plastic film 201, the bent aluminum-plastic film 201 is fixed and pressure-maintained, thereby preventing the bent aluminum-plastic film 201 from rebounding and ensuring the reliability of the folding operation on the aluminum-plastic film 201. Optionally, in this embodiment, the pressure-maintaining mechanism 7 is located outside the support platform 1 and the thickness measuring plate 21 in the left-right direction, and the pressure-maintaining driver 71 drives the pressure-maintaining assembly 72 to move in the left-right direction, so that the pressure-maintaining assembly 72 can abut against the edge of the bent aluminum-plastic film 201. Optionally, the pressure-maintaining driver 71 can be a driving cylinder. It should be noted that the battery sorting equipment provided in this embodiment includes two pressure-maintaining mechanisms 7, which are arranged at intervals in the left-right direction, and the two pressure-maintaining mechanisms 7 respectively abut against the edge of the bent aluminum-plastic film 201 on the corresponding side.

[0058] In the present embodiment, the pressure-maintaining assembly 72 includes a pressure-maintaining mounting frame 721 and a pressure-maintaining roller 722, wherein the pressure-maintaining mounting frame 721 is transmission-connected to the output end of the pressure-maintaining driving member 71, and the pressure-maintaining roller 722 is rotationally connected to the pressure-maintaining mounting frame 721, and the pressure-maintaining roller 722 can roll and abut against the edge of the aluminum-plastic film 201 after bending. By arranging the pressure-maintaining roller 722 and rolling and abutting against the edge of the aluminum-plastic film 201 after bending, the pressure-maintaining operation of the aluminum-plastic film 201 after bending is realized by the pressure-maintaining roller 722, not only the reliability of the pressure-maintaining operation is guaranteed, but also the aluminum-plastic film 201 is avoided from being damaged. Optionally, in the present embodiment, a plurality of pressure-maintaining rollers 722 are arranged at intervals along the front-back direction on the pressure-maintaining mounting frame 721, and the axis of each pressure-maintaining roller 722 extends in the up-down direction.

[0059] Optionally, in this embodiment, the pressure-maintaining mechanism 7 is aligned horizontally (left-right in the figure) with the carrier platform 1 at the loading and unloading station. This arrangement allows the pressure-maintaining mechanism 7 to maintain pressure on the bent aluminum-plastic film 201 while the transfer drive mechanism 5 drives the carrier platform 1 backward from the testing station to the loading and unloading station after the battery 20 has completed testing and folding operations at the testing station.

[0060] Alternatively, in other embodiments, the pressure-holding mechanism 7 may be positioned in the left-right direction opposite the carrier platform 1 at the testing station. This arrangement allows the pressure-holding mechanism 7 to maintain pressure and secure the bent aluminum-plastic film 201 after the battery 20 has completed testing and hemming operations at the testing station. After pressure maintenance is complete, the transport drive mechanism 5 drives the carrier platform 1 back from the testing station to the loading and unloading station.

[0061] In order to facilitate the understanding of the battery sorting equipment disclosed in this embodiment, first combine Figures 1 to 3 Explain the specific working process of the battery sorting equipment:

[0062] First, the battery 20 is placed on the carrier 1 at the loading and unloading station, and then the transfer drive mechanism 5 drives the carrier 1 to move from the loading and unloading station to the testing station;

[0063] Next, the thickness measuring drive 22 drives the thickness measuring plate 21 to move from the avoidance position to the pressing position for pressing the battery 20 , thereby measuring the thickness, voltage and internal resistance of the battery 20 on the carrier 1 ;

[0064] Next, the folding drive 31 drives the folding assembly 32 to press downward against the edge of the aluminum-plastic film 201, thereby performing a folding operation on the aluminum-plastic film 201;

[0065] Then, the thickness measuring drive 22 drives the thickness measuring plate 21 to rise to the avoidance position, the folding drive 31 drives the folding assembly 32 to rise to the initial position, and the transfer drive mechanism 5 drives the carrier 1 to move from the testing station to the loading and unloading station;

[0066] At this time, the pressure-maintaining driving member 71 drives the pressure-maintaining assembly 72 to move toward the direction close to the aluminum-plastic film 201, so that the pressure-maintaining assembly 72 presses against the edge of the bent aluminum-plastic film 201;

[0067] Finally, the pressure-maintaining driving member 71 drives the pressure-maintaining assembly 72 to move away from the aluminum-plastic film 201 and reset, so as to facilitate unloading of the battery 20 from the carrying platform 1 .

[0068] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
