Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, specifically to a lithium battery batch activation device. Background Technology

[0002] Lithium battery activation involves connecting the positive and negative terminals of a power pack with the positive and negative terminals of the lithium battery, similar to charging a battery, to activate the lithium battery.

[0003] According to the authorized announcement number CN218769699U, a lithium battery batch activation device is disclosed, including a base, a mounting frame, and a rotating plate. The rotating plate is rotatably connected to the upper end of the base, and the mounting frame is fixedly connected to the outer side of the upper end of the base. An activation power pack is fixedly connected to the upper end of the mounting frame, and a pair of activation probes are fixedly connected to the inner wall of the upper end of the mounting frame. The activation probes are connected to the activation power pack via wires, and a set of storage frames is movably connected to the rotating plate at positions corresponding to the activation probes.

[0004] In the process of realizing this utility model, the inventors discovered that at least the following problems in the prior art have not been solved. In the above case, the centrifugal wheel is driven by a motor to rotate, so that the outer periphery of the centrifugal wheel intermittently lifts the corresponding storage frame to activate the lithium battery. However, during use, the operator needs to precisely control the relative position of the lithium battery and the activation probe on the inner side of the storage frame. Otherwise, the metal connector at the top of the lithium battery cannot contact the activation probe, which makes the operation difficult and easily affects the work efficiency.

[0005] Therefore, we propose a lithium battery batch activation device that can automatically bring the metal connector at the top of the lithium battery into contact with the activation probe. Utility Model Content

[0006] The purpose of this invention is to provide a lithium battery batch activation device, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery batch activation device, comprising an activation base, a bracket welded to one side of the upper surface of the activation base, an activation power pack fixedly connected to the upper surface of the bracket, and an activation probe disposed at the top of the inner side of the bracket; an adjustment mechanism for adjusting the activation position of the lithium battery, the adjustment mechanism comprising an activation platform, a servo motor, and a second wedge block, a positioning groove being formed on the upper surface of the activation platform, the second wedge block being fixedly installed on the upper surface of the activation base and positioned directly below the activation probe, mounting grooves being evenly formed on the bottom side of the activation platform, a first wedge block being slidably connected to the inner side of the mounting groove, guide rods being vertically fixedly installed on both sides of the upper surface of the first wedge block, a lifting plate being horizontally arranged inside the positioning groove, and the top ends of the two sets of guide rods on the upper surface of the first wedge block being fixedly connected to the bottom side of the lifting plate.

[0008] As an optional embodiment of the technical solution of this application, the second wedge block corresponds to the first wedge block, and the second wedge block is movably connected to the first wedge block.

[0009] As an optional solution to the technical solution of this application, the bottom inner wall of the positioning groove is provided with two sets of guide grooves, and the two sets of guide rods on the upper surface of the first wedge block are slidably connected to the two sets of guide grooves at the bottom of the positioning groove.

[0010] As an optional solution to the technical solution of this application, the positioning grooves are evenly distributed in a ring on the upper surface of the activation platform, and the mounting grooves correspond one-to-one with the positioning grooves.

[0011] As an optional solution to the technical solution of this application, the shaft end of the servo motor is fixedly connected to a connecting rod, the top end of the connecting rod is fixedly connected to the middle part of the bottom side of the activation platform, and the servo motor is fixedly connected to the middle part of the activation seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the lithium battery can be positioned by the positioning groove on the upper surface of the activation platform, the servo motor can be controlled to work, and the activation platform can be rotated through the connecting rod, so that the lithium battery to be activated inside the positioning groove can be rotated to the direct under the activation power pack for activation.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a lithium battery batch activation device, including an activation base 1, a bracket 11 welded to one side of the upper surface of the activation base 1, an activation power pack 12 fixedly connected to the upper surface of the bracket 11, and an activation probe 13 provided at the top of the inner side of the bracket 11; an adjustment mechanism for adjusting the activation position of the lithium battery, the adjustment mechanism including an activation platform 14, a servo motor 16 and a second wedge block 2, a positioning groove 15 opened on the upper surface of the activation platform 14, the positioning groove 15 being evenly distributed in a ring on the upper surface of the activation platform 14, a connecting rod 17 fixedly connected to the shaft end of the servo motor 16, the top end of the connecting rod 17 being fixedly connected to the middle of the bottom side of the activation platform 14, and the servo motor 16 being fixedly connected to the middle of the activation base 1.

[0019] In this technical solution, the lithium battery can be positioned by the positioning groove 15 on the upper surface of the activation platform 14, and the servo motor 16 can be controlled to work. The connecting rod 17 can drive the activation platform 14 to rotate, so that each group of lithium batteries to be activated inside the positioning groove 15 can be rotated to the direct under the activation power pack 12 for continuous activation. Moreover, when collecting the activated lithium batteries, the activation operation of the lithium batteries is not interfered with, thus improving work efficiency.

[0020] In this embodiment, the second wedge block 2 is fixedly installed on the upper surface of the activation seat 1 and placed directly below the activation probe 13. The bottom side of the activation platform 14 is evenly provided with mounting grooves 21, which correspond one-to-one with the positioning grooves 15. The inner side of the mounting groove 21 is slidably connected to the first wedge block 22. The two sides of the upper surface of the first wedge block 22 are vertically fixedly installed with guide rods 23. The inside of the positioning groove 15 is horizontally provided with a lifting plate 24. The top ends of the two sets of guide rods 23 on the upper surface of the first wedge block 22 are fixedly connected to the bottom side of the lifting plate 24.

[0021] In this technical solution, as the activation platform 14 rotates the lithium battery to be activated inside the positioning groove 15 to directly below the activation probe 13, the second wedge block 2 on the upper surface of the activation seat 1 can push the first wedge block 22 upward. Through the guide rod 23, the lifting plate 24 can be pushed upward within the positioning groove 15, thereby pushing the lithium battery to be activated inside the positioning groove 15 upward, so that the metal connector of the lithium battery to be activated automatically contacts the activation probe 13, thus automatically performing the activation operation. After the lithium battery is activated, the servo motor 16 drives... The activation platform 14 rotates, and the first wedge block 22 slides down from the top of the second wedge block 2. Under the gravity of the lithium battery, the lifting plate 24 moves downward in the positioning groove 15, so that the metal connector at the top of the lithium battery automatically separates from the activation probe 13. It should be noted that the dimensions of the first wedge block 22 and the second wedge block 2 are set according to the distance between the activation probe 13 and the metal connector at the top of the lithium battery to ensure that when the first wedge block 22 moves to the top of the second wedge block 2, the metal connector at the top of the lithium battery contacts the bottom of the activation probe 13.

[0022] In this embodiment, two sets of guide grooves 25 are provided through the bottom inner wall of the positioning groove 15. Two sets of guide rods 23 on the upper surface of the first wedge block 22 are slidably connected to the two sets of guide grooves 25 at the bottom of the positioning groove 15. The second wedge block 2 corresponds to the first wedge block 22, and the second wedge block 2 is movably connected to the first wedge block 22.

[0023] In this technical solution, the sliding connection between the guide rod 23 and the guide groove 25 can improve the stability of the lifting plate 24 and the first wedge block 22.

[0024] When using a lithium battery batch activation device, each group of lithium batteries to be activated is placed in the positioning groove 15 on the upper surface of the activation platform 14 to position the lithium batteries. The servo motor 16 is controlled to work, and the activation platform 14 can be rotated via the connecting rod 17. This causes each group of lithium batteries to be activated inside the positioning groove 15 to rotate directly below the activation power pack 12 for continuous activation. During the process of the lithium batteries to be activated inside the positioning groove 15 rotating directly below the activation probe 13, the second wedge block 2 on the upper surface of the activation seat 1 can push the first wedge block 22 upward. The guide rod 23 can push the lifting plate 24 to move upward in the positioning groove 15, thereby pushing the lithium battery to be activated inside the positioning groove 15 to move upward, so that the metal connector of the lithium battery to be activated automatically contacts the activation probe 13, thereby automatically performing the activation operation. After the lithium battery is activated, the servo motor 16 is controlled to drive the activation platform 14 to rotate, the first wedge block 22 slides from the top of the second wedge block 2, and the lifting plate 24 moves downward in the positioning groove 15 under the action of the lithium battery's gravity, so that the metal connector at the top of the lithium battery automatically separates from the activation probe 13.
