Description

Technical Field

[0001] The invention relates to the technical field of lithium battery processing equipment, and in particular to a lithium battery stop frame conveying device. Background Art

[0002] A lithium battery stopper is a component used to fix and protect the internal structure of a lithium battery. It is usually made of plastic, metal or other materials and installed inside the battery casing. The main function of a lithium battery stopper is to fix the battery cell to prevent it from moving or shaking during battery use, thereby ensuring the stability and safety of the battery. In addition, the stopper can also collect welding slag generated during welding to prevent the welding slag from entering the battery cell and causing a short circuit. Lithium battery stoppers are widely used in various types of lithium battery products, including mobile phone batteries, laptop batteries, electric vehicle batteries, etc. By using a stopper, the performance and reliability of the battery can be significantly improved, and the battery life can be extended.

[0003] Specifically, the design of the lithium battery stopper varies depending on the battery type and specification. Most of the existing stoppers used for power lithium batteries include a stopper body, a boss is provided on the first side, and a glue material is provided on the boss. After the cover plate connecting piece is laser welded, the stopper body is adhered to the laser welding seam of the connecting piece through the glue material on the boss. It has a simple structure, low cost, easy installation and reliable adhesion.

[0004] In the processing workshop of lithium battery stop frames, in order to cooperate with the sequential implementation of the processing steps of the stop frame, it is necessary to use conveying equipment to transport the stop frame to each processing station. Due to the space limitations of the production workshop, the stop frame often needs to be moved to conveyor belts of different paths during the transportation process to achieve the purpose of transporting the stop frame along different paths. However, in the process of transferring the stop frame to different conveyor belts, most of the existing conveying equipment needs to replace the tray structure that carries the brake frame or use a suction cup to transfer the stop frame. The stop frame is prone to shaking and offset during the transfer process, and the stability cannot be guaranteed, which affects the accuracy of the plane position distribution of the stop frame, and further affects the stability of the subsequent processing operations of the stop frame. Summary of the invention

[0005] In view of the above problems, the present application provides a lithium battery stop rack conveying device.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a lithium battery stop rack conveying device, comprising a first conveyor belt and a second conveyor belt perpendicular to the conveying path of the first conveyor belt, the first conveyor belt and the second conveyor belt are respectively provided with a dockable conveying platform and a receiving slide, when the conveying platform and the receiving slide are docked and separated, the lithium battery stop rack can be transferred from the conveying platform to the receiving slide.

[0007] The receiving slide is provided with two groups of receiving limit structures which can move synchronously therewith, and the conveying platform is provided with two groups of limit blocks which can avoid along with the movement of the receiving limit structures.

[0009] Furthermore, the conveying platform is provided with a support plate capable of carrying a lithium battery stop frame, and the support plate is provided with a plurality of comb teeth.

[0010] The receiving slide is provided with a comb tooth groove matched with the comb tooth bar. When the receiving slide moves to be connected with the conveying platform, the comb tooth bar is spliced ​​with the comb tooth groove.

[0012] Furthermore, the receiving and limiting structure includes two guide and limiting seats arranged on both sides of the receiving slide, and the guide and limiting seats are trapezoidal in structure.

[0013] The top end of each group of limit blocks is connected to the same support arm through a rotating shaft, and the bottom ends of the limit blocks are distributed in a semicircular structure. When the guide limit seat moves toward the conveyor platform, the inclined surface of the guide limit seat abuts the limit block and rotates successively until it abuts against the lower surface of the support arm until the guide limit seat moves to both sides of the lithium battery stop frame.

[0014] Furthermore, a U-shaped groove is provided on the limit block, and a first roller group is provided at the top of the guide limit seat, which is directly opposite to the position of the U-shaped groove. Second roller groups that can rotate synchronously with the first roller group are provided on both sides of the first roller group. The diameter of the rollers in the second roller group is smaller than the diameter of the rollers in the first roller group. When the inclined surface of the guide limit seat abuts the limit block and rotates continuously, the first roller group moves in the U-shaped groove, and the second roller group moves along the surface of the limit block.

[0015] Furthermore, the two guide limit seats are connected via the same extension frame, the extension frame extends above the support arm, and the extension frame is located above the receiving slide toward the end opposite to the second stop strip.

[0016] A rotatable stop tooth plate is provided below the extension frame. When the stop tooth plate is rotated to be perpendicular to the receiving slide, a plurality of the first stop bars are spliced ​​with the stop tooth plate.

[0017] Furthermore, a shaft sleeve is provided on the side of the stop tooth plate away from the second stop strip, the shaft sleeve is provided with a positioning shaft that can rotate synchronously with the second stop strip, the positioning shaft is installed on the extension frame, and the positioning shaft is provided with a synchronous wheel that can rotate synchronously with the second stop strip.

[0020] In summary, the technical effects and advantages of the present invention are as follows: 1. The present invention is provided with a receiving slide and a conveying table that can be docked. Through the cooperation of the receiving limit structure and the limit block, during the process of transferring the stop frame, the limit operation can always be performed on both sides of the stop frame, which effectively avoids the deviation of the stop frame during the transfer process.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Reference Figure 1-10The lithium battery stopper frame conveying device shown in the figure comprises a first conveyor belt 1 and a second conveyor belt 2 perpendicular to the conveying path of the first conveyor belt 1. The first conveyor belt 1 and the second conveyor belt 2 are respectively provided with a conveying platform 3 and a receiving slide 4 that can be docked. After the conveying platform 3 and the receiving slide 4 are docked and separated, the lithium battery stopper frame can be transferred from the conveying platform 3 to the receiving slide 4, so that the lithium battery stopper frame originally located on the conveying path of the first conveyor belt 1 can be transferred to the conveying path of the second conveyor belt 2. Subsequently, under the transportation of the second conveyor belt 2, the lithium battery stopper frame can be further processed.

[0036] The receiving slide 4 is provided with two sets of receiving limit structures that can move synchronously therewith, and the conveying platform 3 is provided with two sets of limit blocks 33 that can avoid as the receiving limit structures move. When the lithium battery stop frame is distributed on the conveying platform 3, the setting of the limit blocks 33 can effectively prevent the stop frame from deflecting until the stop frame is moved to a position close to the receiving slide 4.

[0037] When the receiving slide 4 moves to connect with the conveying platform 3, the receiving limit structure can replace the limit blocks 33 originally located on both sides of the lithium battery stop frame. When the receiving slide 4 in the docking state is separated from the conveying platform 3, the limit blocks 33 are reset to both sides of the conveying platform 3.

[0038] Therefore, during the process of connecting the receiving slide 4 with the conveying platform 3, the limiting operation can always be performed on both sides of the stop frame, effectively preventing the stop frame from deviating during the transfer process, and maintaining the accuracy of the distribution state of the stop frame in the plane position during the transfer operation of the stop frame, thereby improving the stability of the stop frame when changing the path. This further facilitates the processing operation of the stop frame and improves the accuracy of the processing operation.

[0039] Specifically, the conveying platform 3 is provided with a support plate 31 capable of carrying the lithium battery stop frame, and the support plate 31 is provided with a plurality of comb teeth 311. The receiving slide 4 is provided with comb tooth grooves 41 adapted to the comb tooth bars 311, and when the receiving slide 4 moves to connect with the conveying platform 3, the comb tooth bars 311 are spliced ​​with the comb tooth grooves 41.

[0040] The end of the support plate 31 away from the receiving slide 4 is provided with a plurality of first stop bars 32 arranged in parallel. Therefore, when the support plate 31 transports the stop frame, the end of the support plate 31 close to the receiving slide 4 is in an open state. The end of the receiving slide 4 away from the first stop bar 32 is provided with a plurality of second stop bars 42 arranged in parallel. When the comb tooth bar 311 is spliced ​​with the comb tooth groove 41, the first stop bar 32 and the second stop bar 42 are respectively abutted against the two ends of the lithium battery stop frame. At this time, the first stop bar 32 on the conveying platform 3 and the second stop bar 42 on the receiving slide 4 and the two sets of receiving limit structures can clamp the stop frame, which can fully maintain the stability of the stop frame, effectively avoid the shaking and deviation of the stop frame caused by the docking process of the receiving slide 4 and the conveying platform 3, which is conducive to the stop frame to implement further transfer operations.

[0041] It is worth mentioning that in this embodiment, both the conveying platform 3 and the receiving slide 4 can carry one or multiple lithium battery stoppers, and no matter one or multiple stoppers are transported, their stability can be maintained through reasonable size design. In the actual working environment, different transportation requirements can be met.

[0042] Specifically, the receiving and limiting structure includes two guide and limiting seats 43 arranged on both sides of the receiving slide 4, and the guide and limiting seats 43 are trapezoidal in structure.

[0043] The top end of each group of limit blocks 33 is connected to the same support arm 34 through a rotating shaft, and the bottom ends of the limit blocks 33 are distributed in a semicircular structure. When the guide limit seat 43 moves toward the conveyor platform 3, the inclined surface of the guide limit seat 43 abuts the limit block 33 and rotates successively to abut against the lower surface of the support arm 34 until the guide limit seat 43 moves to both sides of the lithium battery stop frame, so that the limit structure and the limit block 33 can complete the replacement work smoothly.

[0044] When the receiving slide 4 is separated from the conveying platform 3, with the movement of the guide limit seat 43, the limit block 33 can be pulled to the original angle by its own gravity and vertically distributed on both sides of the support plate 31, so as to facilitate the conveyance of the stop frame again.

[0045] Example 2: Figure 4-7 As shown, a U-shaped groove 331 is opened on the limit block 33, and a first roller group 431 is provided at the top of the guide limit seat 43, which is directly opposite to the position of the U-shaped groove 331. Second roller groups 432 that can rotate synchronously with the first roller group 431 are provided on both sides of the first roller group 431. The diameter of the rollers in the second roller group 432 is smaller than the diameter of the rollers in the first roller group 431. When the inclined surface of the guide limit seat 43 abuts the limit block 33 and rotates continuously, the first roller group 431 moves in the U-shaped groove 331, and the second roller group 432 moves along the surface of the limit block 33.

[0046] By combining the first roller group 431, the second roller group 432, the limit block 33 and the U-shaped groove 331 opened on its surface, the friction resistance of the guide limit seat 43 in the contact state with the limit block 33 can be reduced during the movement of the guide limit seat 43 toward or away from the limit block 33, so that the guide limit seat 43 can move quickly and smoothly.

[0047] Therefore, the present application document can improve the accuracy of the transposition of the receiving limit structure and the limit block 33 during the transposition process through a linear transposition method, and also improve the smoothness of the transposition process of the stop frame. This enables the conveying platform 3 and the receiving slide 4 to quickly and smoothly implement the transfer operation of the stop frame. In the process of transferring one or more stop frames, there is no need to use a suction cup to implement the reversing operation, which reduces the time required for the transfer path of the stop frame and improves the efficiency of the transfer work.

[0048] Example 3: Figure 5-10 As shown, based on Example 1 and Example 2, the two guide limit seats 43 are connected by the same extension frame 45, the extension frame 45 extends above the support arm 34, and the extension frame 45 is located above the receiving slide 4 towards the end opposite to the second stop strip 42.

[0049] A rotatable stopper plate 44 is provided below the extension frame 45. When the receiving slide 4 is docked with the conveying platform 3 and before the transfer operation of the conveying platform 3 is implemented, the stopper plate 44 is rotated to be perpendicular to the receiving slide 4, and the first stopper bars 32 are spliced ​​with the stopper plate 44. Subsequently, the receiving slide 4 slides away from the conveying platform 3. At this time, under the action of the stopper plate 44, the second stopper bar 42 and the two guide limit seats 43, the stopper frame can be fully limited, so that the stopper frame remains stable during the subsequent transportation process.

[0050] In order to allow the stop tooth plate 44 to rotate smoothly, a shaft sleeve 441 is provided on the side of the stop tooth plate 44 away from the second stop strip 42, and a positioning shaft 442 that can rotate synchronously with the shaft sleeve 441 is provided. The positioning shaft 442 is installed on the extension frame 45, and a synchronous wheel 443 that can rotate synchronously with the shaft sleeve 441 is provided.

[0051] At the same time, the extension frame 45 is provided with a driving shaft 446 and a motor 447 that can control the rotation of the driving shaft 446. The driving shaft 446 is provided with a synchronous wheel 2 445 that can rotate synchronously therewith. The synchronous wheel 1 443 is connected to the synchronous wheel 2 445 through a synchronous belt 444. Under the connection between the synchronous wheel 1 443 and the synchronous wheel 2 445 and the synchronous belt 444, when the motor 447 drives the driving shaft 446 to rotate, the positioning shaft 442, the shaft sleeve 441 and the stop gear plate 44 can be rotated synchronously.

[0052] The second conveyor belt 2 is provided with a second screw slide 6 that can move along its conveying path, and the second screw slide 6 is provided with a first screw slide 5 that can move along the conveying path of the first conveyor belt 1, and the receiving slide 4 is provided on the first screw slide 5. The second screw slide 6 can carry the first screw slide 5 and the receiving slide 4 to move to the same path as the conveying platform 3, and then the first screw slide 5 can drive the receiving slide 4 to move toward the conveying platform 3 until the receiving slide 4 is docked with the conveying platform 3.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
