Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing equipment technology, and specifically discloses a lithium battery pack winding fixture. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-hydrolyzed electrolyte solution. Lithium-ion batteries store and release electrical energy by moving lithium ions back and forth between the positive and negative electrodes. During discharge, lithium ions move from the negative electrode to the positive electrode, and during charging, lithium ions return to the negative electrode. Lithium-ion batteries can be divided into two types: lithium metal batteries and lithium-ion batteries. During the manufacturing process of lithium-ion batteries, a winding device is usually used to wrap tape around the outer surface of multiple lithium-ion batteries to combine multiple individual lithium-ion batteries together to form a lithium-ion battery pack, thereby improving the battery pack's range.

[0003] Chinese patent CN220796825U discloses a lithium battery pack winding fixture, including a frame; a lithium battery positioning seat having a lithium battery positioning area and connected to the frame; two fixed collars sleeved outside the lithium battery positioning area and connected to the frame; the two fixed collars are axially spaced apart, and a movable collar is rotatably connected to the fixed collar, and a film mounting seat is connected to the movable collar. The purpose of this utility model is to solve the technical problems existing in the prior art and provide a lithium battery pack winding fixture, which can significantly improve the speed and quality of manual tape winding. However, the above-mentioned winding fixture requires the worker to manually rotate the movable collar to make the tape roll rotate on the outside of the lithium battery pack. During the rotation, the lithium battery pack is easily moved, which affects the efficiency of tape winding to a certain extent. The above-mentioned winding fixture does not have the function of moving the tape roll up and down during use, which means that the above-mentioned winding fixture can only wind the tape at a fixed position of the lithium battery and cannot evenly wind the tape on the vertical surface of the lithium battery pack, increasing the limitations of the above-mentioned winding fixture. Therefore, in order to solve the above problems, this utility model proposes a lithium battery pack winding fixture. Utility Model Content

[0004] The present invention aims to provide a lithium battery pack winding fixture, which can drive the lithium battery pack to rotate via an electric turntable, thereby preventing the lithium battery pack from shifting position and ensuring the quality and efficiency of tape winding. It has a mechanism for the tape to move up and down, which can evenly wind the tape on the vertical surface of the lithium battery pack, thus improving the practicality of the winding fixture.

[0005] This utility model is achieved through the following technical solution:

[0006] A lithium battery pack winding fixture includes a base with tape placement mechanisms at both ends. A lithium battery pack body is placed on top of the base, and a limiting mechanism is provided above the lithium battery pack body. The base includes a support plate with mounting holes inside. An electric turntable is installed inside the mounting holes. The tape placement mechanism includes an L-shaped plate and a first telescopic rod. The first telescopic rod is connected inside the L-shaped plate, and a support plate is connected to the telescopic end of the first telescopic rod. A limiting post is connected above the support plate, and a roll of tape is sleeved on the outside of the limiting post. The limiting mechanism includes a first pressure plate with a second telescopic rod connected to the upper center of the first pressure plate. Clamping plates are provided at both ends of the first pressure plate, and a second pressure plate is provided inside the first pressure plate. A third telescopic rod is connected to both ends of the second pressure plate, and a first bracket is connected to the outside of the third telescopic rod and the first telescopic rod. A second bracket is provided on one side of the first bracket.

[0007] As a further feature of the above solution, multiple support legs are connected to both sides of the lower part of the support plate, which can provide stable support for the support plate and the components above it. The L-shaped plate is detachably connected to the support plate, which facilitates the installation and maintenance of the L-shaped plate and the tape placement mechanism. A controller is provided on one side of the support plate to facilitate the control of the operation of the relevant components in the tooling.

[0008] As a further feature of the above solution, the tray and the limiting post are detachably connected to facilitate the installation and maintenance of the limiting post. The limiting post is rotatably connected to the tape roll to ensure that the tape roll rotates during the winding of the lithium battery pack. The upper end of the limiting post is detachably connected to a limiting plate to restrict the position of the tape roll and prevent the tape roll from falling off during the winding of the lithium battery pack.

[0009] As a further feature of the above scheme, the first pressure plate is provided with a limiting groove inside, and two through holes are symmetrically provided at the bottom of the limiting groove. The telescopic end of the third telescopic rod passes through the inside of the through hole. The second pressure plate slides in cooperation with the inner wall of the limiting groove, and the position of the second pressure plate can be adjusted by the extension and retraction of the third telescopic rod, so that the lower plane of the second pressure plate is on the same plane as the lower plane of the first pressure plate after the third telescopic rod is fully retracted.

[0010] As a further feature of the above solution, handles are connected to both sides of the first pressure plate to facilitate the user's gripping during the process of adjusting the angle of the first pressure plate and aligning the first and second pressure plates with the lithium battery pack. Two springs are connected to both ends of the first pressure plate, and each spring has a limit rod inside. One end of the limit rod is connected to the first clamping plate, and the ends of the two springs away from the first pressure plate are connected to the clamping plate. This can restrict the position of the lithium battery pack from both ends and clamp the lithium battery pack. The limit rod passes through the interior of the clamping plate and is slidably connected to the clamping plate, which can restrict the movement direction of the clamping plate.

[0011] As a further feature of the above scheme, both the second and third telescopic rods are detachably connected to the first bracket, facilitating the installation and maintenance of the two types of telescopic rods. A support shaft is connected to the upper center of the first bracket, and the support shaft passes through the top of the second bracket and is rotatably connected to the second bracket. This ensures that the first bracket, the first telescopic rod, the second telescopic rod, and the first pressure plate rotate with the lithium battery pack during its rotation, guaranteeing the limiting effect of the limiting mechanism on the lithium battery pack. The lower end of the second bracket is detachably connected to the bearing plate, facilitating the installation and maintenance of the second bracket and the entire limiting mechanism.

[0012] The first pressure plate, the second pressure plate, and the clamping plate in this utility model are all made of elastic material.

[0013] The present invention has the following beneficial effects during use:

[0014] The electric turntable in the base rotates the lithium battery pack during the tape wrapping process, eliminating the need for manual rotation and saving the user's effort. The first telescopic rod in the tape placement mechanism moves the tape up and down during the tape wrapping process, ensuring that the tape is evenly wrapped at different positions on the outer surface of the lithium battery pack, thus guaranteeing the quality of the tape wrapping. The limiting plate prevents the tape from falling off the limiting post and tray during the wrapping process, reducing the user's workload in picking up and placing the tape.

[0015] The combination of the first pressure plate, spring, and two clamping plates in the limiting mechanism can clamp and fix the lithium battery pack from both sides of the upper end during winding, so that the electric turntable can drive the lithium battery pack to rotate. Tape is then wrapped around the lower surface of the lithium battery pack to fix it. The use of the second pressure plate and the third telescopic rod allows the second pressure plate to be pushed out of the limiting groove after the lithium battery pack is fixed by retracting the second telescopic rod. This causes the second pressure plate to squeeze the lithium battery pack from above, fixing it in place. This separates the first pressure plate and clamping plates from the lithium battery pack, preventing the clamping plates from affecting the wrapping of the tape on the upper surface of the lithium battery pack. This ensures that the tape completely covers the lithium battery pack and guarantees the quality of the tape wrapping. Attached Figure Description

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-7 This application will be described in detail with reference to the embodiments.

[0027] An embodiment discloses a lithium battery pack winding fixture, including a base 1, with tape placement mechanisms 2 at both ends of the base 1. A lithium battery pack body 3 is placed on top of the base 1, and a limiting mechanism 4 is provided above the lithium battery pack body 3. The base 1 includes a support plate 11, with mounting holes 111 inside the support plate 11. An electric turntable 13 is installed inside the mounting holes 111. The tape placement mechanism 2 includes an L-shaped plate 21 and a first telescopic rod 22. The first telescopic rod 22 is connected inside the L-shaped plate 21, and the telescopic end of the first telescopic rod 22 is connected to... The device includes a tray 23, with a limiting post 24 connected to the top of the tray 23. A roll of tape 26 is fitted around the outside of the limiting post 24. The limiting mechanism 4 includes a first pressure plate 41, with a second telescopic rod 43 connected to the upper center of the first pressure plate 41. Clamping plates 42 are provided at both ends of the first pressure plate 41. A second pressure plate 44 is provided inside the first pressure plate 41. A third telescopic rod 45 is connected to both ends of the second pressure plate 44. A first bracket 46 is connected to the outside of the third telescopic rod 45 and the first telescopic rod 22. A second bracket 47 is provided on one side of the first bracket 46.

[0028] like Figure 1 and Figure 2 As shown, multiple support legs 12 are connected to both sides of the lower part of the support plate 11, which can provide stable support for the support plate 11 and the components above it. The L-shaped plate 21 is detachably connected to the support plate 11, which facilitates the installation and maintenance of the L-shaped plate 21 and the tape placement mechanism 2. A controller 5 is provided on one side of the support plate 11 to facilitate the control of the operation of the relevant components in the tooling.

[0029] like Figure 1 and Figure 3As shown, the tray 23 is detachably connected to the limiting post 24, which facilitates the installation and maintenance of the limiting post 24. The limiting post 24 is rotatably connected to the tape roll 26, which ensures that the tape roll 26 rotates during the winding of the lithium battery pack. The upper end of the limiting post 24 is detachably connected to the limiting plate 25, which can limit the position of the tape roll 26 and prevent the tape roll 26 from falling off during the winding of the lithium battery pack.

[0030] like Figure 4 and Figure 5 As shown, the first pressure plate 41 is provided with a limiting groove 411 inside. The bottom of the limiting groove 411 is symmetrically provided with two through holes 412. The telescopic end of the third telescopic rod 45 passes through the inside of the through hole 412. The second pressure plate 44 slides with the inner wall of the limiting groove 411. The position of the second pressure plate 44 can be adjusted by the extension and retraction of the third telescopic rod 45 so that the lower plane of the second pressure plate 44 is on the same plane as the lower plane of the first pressure plate 41 after the third telescopic rod 45 is fully retracted.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, handles 413 are connected to both sides of the first pressure plate 41, which facilitates the user to adjust the angle of the first pressure plate 41 and grip the components such as the first pressure plate 41 and the second pressure plate 44 during the alignment with the lithium battery pack. Two springs 414 are connected to both ends of the first pressure plate 41. Each spring 414 has a limit rod 415 inside. One end of the limit rod 415 is connected to the first clamping plate 42, and the ends of the two springs 414 away from the first pressure plate 41 are connected to the clamping plate 42. This can limit the position of the lithium battery pack from both ends and clamp the lithium battery pack. The limit rod 415 passes through the interior of the clamping plate 42 and is slidably connected to the clamping plate 42, which can limit the movement direction of the clamping plate 42.

[0032] like Figure 1 , Figure 6 and Figure 7 As shown, the second telescopic rod 43 and the third telescopic rod 45 are both detachably connected to the first bracket 46, which facilitates the installation and maintenance of the two types of telescopic rods. A support shaft 461 is connected to the upper middle part of the first bracket 46. The support shaft 461 passes through the top of the second bracket 47 and is rotatably connected to the second bracket 47. This ensures that the first bracket 46, the first telescopic rod 22, the second telescopic rod 43, and the first pressure plate 41 rotate with the lithium battery pack during the rotation of the lithium battery pack, thus ensuring the limiting effect of the limiting mechanism 4 on the lithium battery pack. The lower end of the second bracket 47 is detachably connected to the bearing plate 11, which facilitates the installation and maintenance of the second bracket 47 and the entire limiting mechanism 4.

[0033] The lithium battery pack winding fixture disclosed in this embodiment involves removing two limiting plates 25 from the upper ends of the limiting posts 24 and placing them aside before use. Two rolls of adhesive tape 26 are then placed on the two limiting posts 24. The limiting plates 25 are reset to restore the connection between them. Multiple lithium batteries to be wound are placed sequentially on the electric turntable 13 to form the lithium battery pack body 3. The handle 413 on one side of the first pressure plate 41 is grasped, and the orientation of components such as the first bracket 46, the first pressure plate 41, and the second telescopic rod 43 is adjusted so that the support shaft 461 rotates on the top of the second bracket 47. The first pressure plate 41 is aligned with the long side of the initially formed lithium battery pack body 3. The controller 5 simultaneously controls the winding process. The second telescopic rod 43 and the third telescopic rod 45 extend, pushing the first pressure plate 41 and the second pressure plate 44 toward the lithium battery pack body 3. When the first pressure plate 41 and the second pressure plate 44 are in contact with the upper surface of the lithium battery pack body 3, the second telescopic rod 43 and the third telescopic rod 45 are closed, so that the second pressure plate 44 and the first pressure plate 41 simultaneously squeeze the lithium battery pack body 3 from above, initially fixing the lithium battery pack body 3. The two clamping plates 42 pull the spring 414 toward both ends of the first pressure plate 41, so that the limiting rod 415 slides inside the clamping plate 42. Under the rebound action of the spring 414, the two clamping plates 42 squeeze the lithium battery pack body 3 from both ends, further fixing the lithium battery pack body 3.

[0034] Using controller 5, the first telescopic rod 22 in the tape placement mechanism 2 is extended and retracted to adjust the lower edge of the tape to align with the lower edge of the lithium battery pack body 3. The first telescopic rod 22 is then closed, and the tape end is pulled and adhered to the vertical surface of the lithium battery pack body 3. Controller 5 is then activated to start the electric turntable 13, causing it to rotate the lithium battery pack body 3, the first pressure plate 41, the second pressure plate 44, and the first bracket 46, among other components, to evenly wrap the tape around the surface of the lithium battery pack body 3. During the wrapping process, the first telescopic rod 22 below the tape connected to the lithium battery pack body 3 is slowly extended, allowing the tape to slowly move from below the vertical surface of the lithium battery pack body 3 towards the lithium battery pack. The tape is wrapped around the upper part of the main body 3. During the wrapping process, the controller 5 controls the second telescopic rod 43 to retract, so that the first pressure plate 41 and the two clamping plates 42 are separated from the lithium battery pack main body 3. The second pressure plate 44 is pushed out from the limiting groove 411, so that the second pressure plate 44 restricts the position of the lithium battery pack main body 3 from above, so as to prevent the tape from contacting the clamping plates 42 during the wrapping process. The clamping plates 42 are wrapped into the lithium battery pack together to ensure the quality of the tape wrapping the upper part of the lithium battery pack. When the upper part of the lithium battery pack main body 3 is completely wrapped in the tape, the first telescopic rod 22 can be controlled to slowly retract and extend, so as to drive the tape to slowly move downward and upward, so as to wrap multiple layers of tape on the outside of the lithium battery pack main body 3.

[0035] After winding is completed, use controller 5 to turn off electric turntable 13 and first telescopic rod 22. Use controller 5 to simultaneously control the retraction of two third telescopic rods 45, so that the second pressure plate 44 is separated from the lithium battery pack body 3. The second pressure plate 44 is completely retracted into the limiting groove 411. Use a tool to cut the tape and remove the lithium battery pack body 3 wrapped with tape from electric turntable 13. Repeat the above operation to continue the winding operation of the lithium battery pack. When the tape on the outside of the tape roll 26 in one tape placement mechanism 2 is used up, immediately turn off electric turntable 13, stick the tape end in another tape placement mechanism 2 to the vertical surface of the lithium battery pack, start electric turntable 13 and first telescopic rod 22 to continue the winding operation of the lithium battery pack tape. Remove the limiting plate 25 at the upper end of the limiting post 24 inside the core of the empty tape roll 26, remove the core, put the core of another new tape roll 26 on the limiting post 24, and reset the limiting plate 25 for later use.

[0036] The components of the lithium battery pack body 3, controller 5, bearing plate 11, electric turntable 13, first telescopic rod 22, limiting post 24, tape roll 26, handle 413, spring 414, limiting rod 415, clamping plate 42, second telescopic rod 43, third telescopic rod 45, and support shaft 461 disclosed in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
