Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a lithium battery packaging mechanism. Background Technology

[0002] After assembly, lithium batteries require a heat-shrinkable protective film for moisture and dust protection. Patent application number 202321588511.0 discloses a lithium battery packaging mechanism, including a base, an upper heating mechanism, a lower heating mechanism, a moving mechanism, and a frame. The frame is mounted on the base. The upper and lower heating mechanisms are respectively positioned opposite each other on the upper surface of the base and the lower surface of the top plate of the frame. The moving mechanism is mounted on the base and has a sliding plate with a battery slot at its center. The moving mechanism drives the sliding plate to move between the mounting point and the heating point. When the sliding plate is in the heating position, the battery slot is located between the upper heating mechanism and the lower heating mechanism. During the lithium battery heat-shrink protective film encapsulation process, it can avoid human hands coming into contact with hot air, making it safe and convenient to use. However, after the heat-shrink encapsulation is completed, the sliding plate needs to be removed from the heating mechanism. Then, the encapsulated battery is removed and a new battery is placed in it. After that, the sliding plate moves back to the heating mechanism. During this process, the sliding plate will cool down. After the sliding plate moves to the heating mechanism, it needs a certain amount of time to heat the sliding plate to reach the required temperature, resulting in low efficiency.

[0005] To further optimize this technical solution, multiple sets of support plates are provided on the motor shaft, and these multiple sets of support plates are symmetrically distributed about the axis of the motor shaft.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0014] Detailed implementation method: combined with Figure 1-3As shown, a lithium battery packaging mechanism includes a worktable 1. A backplate 11 is disposed above the rear side of the worktable 1. An upper heating mechanism 12 and a lower heating mechanism 15 are disposed on the backplate 11. A heat-shrinkable plate 13 is located between the upper heating mechanism 12 and the lower heating mechanism 15, and there is a gap between the heat-shrinkable plate 13 and both the upper heating mechanism 12 and the lower heating mechanism 15. The rear end of the heat-shrinkable plate 13 is fixed to the backplate 11. A baffle 14 is located between the heat-shrinkable plate 13 and the upper heating mechanism 12. The baffle 14 is preferably located on one side of the heat-shrinkable plate 13. There is a gap between the baffle 14 and the heat-shrinkable plate 13, and the height of the gap is slightly greater than the thickness of the lithium battery to be packaged. A motor 2 is also disposed on the worktable 1. A tray assembly 3 is provided on the rotating shaft. The extension directions of the heat shrink plate 13 and the tray assembly 3 are both perpendicular to the axis of the rotating shaft of the motor 2. The tray assembly 3 includes a first tray 31 and a second tray 32. The first tray 31 and the second tray 32 are made of materials with poor thermal conductivity. The thickness of the first tray 31 is slightly less than the thickness of the lithium battery to be packaged. The second tray 32 is located in front of the first tray 31 in the direction of rotation. When the motor 2 rotates, the first tray 31 can pass between the baffle 14 and the heat shrink plate 13, and the second tray 32 can pass between the heat shrink plate 13 and the lower heating mechanism 15. The gap between the second tray 32 and the first tray 31 should not be too large, and the two should preferably partially overlap in the horizontal direction.

[0015] Furthermore, the motor 2 has multiple sets of support plates 3 on its rotating shaft. These multiple sets of support plates 3 are symmetrically distributed about the axis of the motor 2 rotating shaft. When the motor 2 rotates, the multiple sets of support plates 3 pass through the heat shrink plate 13 in sequence.

[0016] Furthermore, the motor 2 is located below the workbench 1, and the rotating shaft of the motor 2 penetrates upward through the workbench 1. The pallet assembly 3 is located above the workbench 1.

[0017] Furthermore, the heat shrink plate 13 is made of aluminum, which has good thermal conductivity, and the baffle 14 is also preferably made of aluminum.

[0018] Working principle: Motor 2 rotates continuously, driving the tray assembly 3 to rotate slowly. After manually covering the lithium battery with heat-shrink film, the battery is placed on the upper surface of the first tray 31, with the length direction of the lithium battery (with the electrodes at its ends) as perpendicular as possible to the radius of the virtual circle it forms during circular motion. The openings on both sides of the heat-shrink film are positioned on either side of the width direction of the lithium battery. When the first tray 31, containing the lithium battery, moves to the position of the stop bar 14, it is blocked by the stop bar 14, and the heat-shrink film passes under the stop bar 14. The lithium battery falls onto the heat-shrinkable plate 13. The upper heating mechanism 12 and the lower heating mechanism 15 (which are always in operation, blowing out hot air at a basically constant temperature) heat the heat-shrinkable film, causing it to shrink and tighten around the lithium battery. When the next first tray 31, which holds a lithium battery with the heat-shrinkable film, moves to the heat-shrinkable plate 13 and its front side touches the lithium battery that has already been packaged on the heat-shrinkable plate 13, it will push the packaged lithium battery to move and fall from the heat-shrinkable plate 13 onto the second tray 32, which is in the same tray group 3 as the first tray 31. Figure 1 The motor 2 rotates counterclockwise, and the lithium battery to be packaged on the first tray 31 falls onto the heat shrink plate 13 under the obstruction of the baffle 14. When the tray group 3 moves to the front of the workbench 1, the lithium battery that has been packaged on the second tray 32 can be removed, and the lithium battery covered with heat shrink film can be placed on the first tray 31. In this way, the lithium battery packaging work can be continuously carried out, and the heat shrink plate 13 is always between the upper heating mechanism 12 and the lower heating mechanism 15 and basically does not cool down, so the efficiency is high.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
