Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery packaging technology, and in particular to a fixture for polymer lithium battery packaging. Background Technology
[0002] A lithium-ion battery is a type of rechargeable battery that primarily works by the movement of lithium ions between the positive and negative electrodes. During charging and discharging, Li+ ions move back and forth between the two electrodes, inserting and de-inserting: during charging, Li+ ions are de-inserted from the positive electrode, pass through the electrolyte, and insert into the negative electrode, leaving the negative electrode in a lithium-rich state; the opposite occurs during discharging.
[0003] Before encapsulation, existing lithium batteries typically require uniform fixation before the next encapsulation step can proceed. However, existing fixing equipment can scratch the encapsulated surface of the lithium battery after encapsulation due to the clamping state of the fixing components, causing gaps in the surface structure and affecting the lifespan and performance of the lithium battery, thereby increasing the processing cost of lithium batteries.
[0004] To address this, we designed a fixture for polymer lithium battery packaging. Utility Model Content
[0005] The purpose of this invention is to provide a polymer lithium battery encapsulation fixture to address the problem that existing technologies easily lead to damage to the lithium battery casing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A clamp for packaging polymer lithium batteries includes a body, a placement slot on the body, a battery body placed in the placement slot, and clamping plates symmetrically arranged on the body for clamping the battery body.
[0008] The body is symmetrically provided with a closed body for fixing the battery body, and the body is symmetrically provided with a second rotating shaft for rotating the closed body.
[0009] Preferably, the machine body is provided with symmetrical slides, the slides are fixedly connected to the machine body through a support body, and the clamping plate is slidably connected on the slides.
[0010] Preferably, the machine body is symmetrically provided with sliding rods, and the machine body is symmetrically provided with first rotating shafts, and the enclosed body is rotatably connected on the first rotating shafts.
[0011] Preferably, the slide rod has a clamping slot, a guide groove at one end, and an auxiliary rod for correcting the battery body.
[0012] Preferably, the second rotating shaft is fixedly connected to the machine body via a support body, and the second rotating shaft is fixedly connected to the enclosed body via a guide rod, wherein the enclosed body is provided with a curved groove.
[0013] Preferably, the curved groove is provided with a plurality of auxiliary sliders for protecting the sidewalls of the battery body, and the auxiliary sliders are fixedly connected in the curved groove by a hanger.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. By setting up a closed body and a first rotating shaft, this utility model can effectively prevent damage to the surface structure at both ends of the battery body during the clamping process of the clamping plate. At the same time, it can smooth the adhesive edge of the surface structure. Furthermore, the closed body can effectively reduce the shaking of the battery body during the clamping process, thereby reducing the damage that occurs during the processing of the battery body and thus reducing the processing cost of the battery body.
[0016] 2. By setting up a guide groove and an auxiliary slider, this utility model can effectively reduce the impact on the side wall of the battery body when it first enters the clamping gap, thereby protecting the side wall of the battery body. At the same time, the auxiliary slider can effectively guide the battery body to continue to penetrate deeper into the clamping gap, thereby reducing the damage to the surface structure of the battery body caused by impact.

[0022] Reference Figures 1-4A clamp for encapsulating polymer lithium batteries includes a body 1, which is a commonly used electrically driven device in the prior art. The entire body 1 is driven by an external power source, allowing the entire body 1 to be driven by electricity. A placement slot is opened in the center of the body 1, which is mainly used to place the encapsulated battery body 2 and to harden the connection of the surface structure of the current battery body 2, so as not to be interfered with by other structures. The battery body 2 is a lithium battery in the prior art, which is fully encapsulated but the surface structure is not completely solidified. It needs time to solidify and ensure that the surface structure is not affected by external structures during the static process, so as not to cause peeling or lifting. The clamping plate 3 is a metal component used in the prior art to clamp lithium batteries.
[0023] The body 1 is symmetrically provided with slides. The slides are long rectangular structures with a sliding buckle structure at the top. The sliding buckle can slide on the slides. The slides are fixedly connected to the body 1 through a support body. The support body is an auxiliary component used to support the slides on the body 1. The support body is fixedly connected to the slides and the body 1 by welding. The clamping plate 3 is slidably connected on the slides. One end of the clamping plate 3 is fixedly connected to the sliding buckle.
[0024] The main body 1 is symmetrically provided with a closed body 5 for fixing the battery body 2. The closed body 5 is mainly used to cover the side end of the battery body 2, so that the battery body 2 can only be pulled back and forth, thereby reducing the effect of left and right swaying. The main body 1 is symmetrically provided with a sliding rod 4. The sliding rod 4 is mainly used to support the side end of the battery body 2, so that the battery body 2 is restricted between the sliding rod 4 and the closed body 5, while leaving a gap to reduce the scratches caused by the closed body 5 to the surface structure of the battery body 2. The main body 1 is symmetrically provided with a first rotating shaft 6. The first rotating shaft 6 is mainly used to rotate the closed body 5 so that it is in the open state before fixing the battery body 2, so that the side wall of the battery body 2 can contact the sliding rod 4. The closed body 5 is rotatably connected on the first rotating shaft 6, and the tail end of the closed body 5 is fixedly connected to the first rotating shaft 6.
[0025] The slide rod 4 has a clamping slot 7, which is used to place the battery body 2, that is, the space between the slide rod 4 and the enclosure 5. One end of the slide rod 4 has a guide groove 8, which is used to reduce the contact range of the surface structure of the battery body 2 and reduce the friction at the connection of the surface structure. The slide rod 4 has an auxiliary rod for correcting the battery body 2. The auxiliary rod is used to correct the side wall of the battery body 2 so that it is correctly guided before entering the clamping slot 7.
[0026] The body 1 is symmetrically provided with a second rotating shaft 9 for rotating the closed body 5. The second rotating shaft 9 is mainly used to assist the rotation of the closed body 5 and ensure that the rotation effect of the closed body 5 is improved. The second rotating shaft 9 is fixedly connected to the body 1 through a support body. The support body is an auxiliary component used for the fixed connection between the second rotating shaft 9 and the body 1. The two ends of the support body are fixedly connected to both by welding. The second rotating shaft 9 is fixedly connected to the closed body 5 through a guide rod 10. The guide rod 10 is an auxiliary connecting component used for the second rotating shaft 9 to connect the closed body 5, so as to improve its smoothness during the flipping process. The closed body 5 is provided with a curved groove, which is used to adapt to the side wall of the battery body 2.
[0027] The curved groove is equipped with multiple auxiliary sliders 11 for protecting the side walls of the battery body 2. The auxiliary sliders 11 are made of rubber and have moderate overall hardness. They can smooth the surface structure of the battery body 2 while reducing the peeling and damage of the surface structure. The auxiliary sliders 11 are fixedly connected in the curved groove by a hanger rod. The hanger rod is an auxiliary component used to suspend the auxiliary sliders 11 in the curved groove.
[0028] The working principle of this utility model is as follows:
[0029] First, the fully encapsulated lithium battery body 2, but with its surface structure not yet fully solidified, is placed in the placement slot in the center of the body 1. At this time, the side wall of the battery body 2 contacts the slide bar 4, ensuring that the battery can only be pulled back and forth, reducing lateral swaying. Then, the clamping plate 3 is slidably connected to the position of the battery body 2 along the slide bar via the sliding buckle structure on the slide. One end of the clamping plate 3 is fixedly connected to the sliding buckle, and the other end contacts the side wall of the battery body 2, thus confining the battery body 2 between the slide bar 4 and the sealing body 5. Then, the sealing body 5 is rotated by the first rotating shaft 6, so that it is in the open state before fixing the battery body 2. In this way, the side wall of the battery body 2 can smoothly contact the slide bar 4. At the same time, the guide groove 8 is used to reduce the contact range of the surface structure of the battery body 2 and reduce the friction force. When the battery body 2 enters the clamping slot 7, the auxiliary rod will correct its side wall to guide it correctly. At this time, multiple auxiliary sliding balls 11 within the curved groove protect the sidewalls of the battery body 2, preventing surface peeling and damage. Finally, the second rotating shaft 9 assists in the rotation of the closure 5, ensuring that the closure 5 can smoothly flip and cover the side of the battery body 2. Throughout the process, the support plays a role in fixing and connecting, ensuring the stability and smoothness of each component.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
