Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery processing equipment, and particularly relates to a conveying device for a lithium battery stop bracket. Background Art

[0002] A lithium battery stop bracket 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 case. The main function of the lithium battery stop bracket is to fix the battery core to prevent it from moving or shaking during battery use, thereby ensuring the stability and safety of the battery. In addition, the stop bracket can also collect the welding slag generated during the welding process to prevent the welding slag from entering the battery core and causing a short circuit. Lithium battery stop brackets are widely used in various types of lithium battery products, including mobile phone batteries, laptop computer batteries, electric vehicle batteries, etc. By using a stop bracket, the performance and reliability of the battery can be significantly improved, and the service life of the battery can be extended.

[0003] Specifically, the design of the lithium battery stop bracket varies depending on the type and specifications of the battery. Most of the existing stop brackets applied to power lithium batteries include a stop bracket body, with a boss provided on the first side, and a glue material provided on the boss. After the laser welding of the cover plate connecting piece is completed, the stop bracket body is pasted at the laser welding seam of the connecting piece through the glue material on the boss. The structure is simple, the cost is low, the installation is easy and the paste is firm.

[0004] In the processing workshop of lithium battery stop brackets, in order to cooperate with the sequential implementation of the stop bracket processing steps, a conveying device is needed to transfer the stop brackets to each processing station. Due to the site limitations of the production workshop, during the conveying process of the stop brackets, they often need to be moved to conveyor belts with different paths to achieve the purpose of conveying the stop brackets along different paths. However, for the existing conveying devices, during the process of transferring the stop brackets to different conveyor belts, most of them need to replace the tray structure for carrying the brake bracket or use a suction cup to transfer the stop brackets. The stop brackets are prone to shaking and offset during the transfer process, and the stability cannot be guaranteed, which affects the accuracy of the planar position distribution of the stop brackets and further affects the stability of the subsequent processing operations of the stop brackets. Summary of the Invention

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

[0006] To achieve the above object, the present application provides the following technical solution: A conveying device for a lithium battery stop bracket, including 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 conveyable transfer table and a receiving sliding table. After the transfer table and the receiving sliding table are docked and separated, the lithium battery stop bracket can be transferred from the transfer table to the receiving sliding table.

[0007] The receiving slide is provided with two sets of receiving limit structures that can move synchronously therewith, and the conveying platform is provided with two sets of limit blocks that can avoid as the receiving limit structures move.

[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 contact with the conveying platform, the comb tooth bar and the comb tooth groove are spliced.

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

[0013] The top of each group of limit blocks is connected to the same support arm through a rotating shaft, and the bottom 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 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, and 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 by 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 bar.

[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 strips are spliced ​​with the stop tooth plate.

[0017] Further, a bushing is provided on the side of the stop tooth plate away from the second stop bar. A positioning rotating shaft that can rotate synchronously with the bushing is provided on the bushing.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1: Refer to Figures 1-10A lithium battery stopper conveying device shown in the figure includes a first conveyor belt 1 and a second conveyor belt 2 perpendicular to the conveying path of the first conveyor belt 1. A conveyer table 3 and a receiving sliding table 4 which can be docked are respectively arranged on the first conveyor belt 1 and the second conveyor belt 2. After the conveyer table 3 and the receiving sliding table 4 are docked and separated, the lithium battery stopper can be transferred from the conveyer table 3 to the receiving sliding table 4, and then the lithium battery stopper 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, further processing operations can be performed on the lithium battery stopper.

[0037] Two groups of receiving limiting structures that can move synchronously with it are arranged on the receiving sliding table 4, and two groups of limiting blocks 33 that can avoid being displaced as the receiving limiting structures move are arranged on the conveyer table 3. When the lithium battery stopper is distributed on the conveyer table 3, the arrangement of the limiting blocks 33 can effectively prevent the stopper from shifting until the stopper is moved to a position close to the receiving sliding table 4.

[0038] When the receiving sliding table 4 moves to be docked with the conveyer table 3, the receiving limiting structure can replace the limiting blocks 33 originally located on both sides of the lithium battery stopper. When the receiving sliding table 4 in the docked state is separated from the conveyer table 3, the limiting blocks 33 are reset to both sides of the conveyer table 3.

[0039] Therefore, during the docking process of the receiving sliding table 4 and the conveyer table 3, limiting operations can always be performed on both sides of the stopper, effectively preventing the stopper from shifting during the transfer process, and maintaining the accuracy of the distribution state of the stopper in the plane position during the transfer operation of the stopper, improving the stability of the stopper during the movement of the conversion path. It is further convenient to perform processing operations on the stopper and improves the accuracy of the processing operations.

[0040] Specifically, a pallet 31 for carrying the lithium battery stopper is arranged on the conveyer table 3, and a plurality of comb teeth 311 are arranged on the pallet 31. The receiving sliding table 4 is provided with a comb tooth groove 41 adapted to the comb teeth 311. When the receiving sliding table 4 moves to be docked with the conveyer table 3, the comb teeth 311 are spliced with the comb tooth groove 41.

[0041] One end of the pallet 31 away from the receiving sliding table 4 is provided with a plurality of first stop bars 32 arranged in parallel. Therefore, when the pallet 31 transports the stop frame, one end of the pallet 31 close to the receiving sliding table 4 is in an open state. And one end of the receiving sliding table 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 respectively abut against both ends of the lithium battery stop frame. At this time, the first stop bar 32 located on the conveying table 3, the second stop bar 42 located on the receiving sliding table 4 and the two groups of receiving limiting structures can clamp the stop frame, comprehensively maintaining the stability of the stop frame, effectively avoiding the shaking and offset of the stop frame caused during the docking process of the receiving sliding table 4 and the conveying table 3, which is beneficial to the further transfer operation of the stop frame.

[0042] It is worth mentioning that in this embodiment, both the conveying table 3 and the receiving sliding table 4 can carry one or a plurality of stacked lithium battery stop frames. Whether transporting one or multiple stop frames, through reasonable size design, their stability can be maintained. In the actual working environment, different transportation requirements can be met.

[0043] Specifically, the receiving limiting structure includes two guiding and limiting seats 43 arranged on both sides of the receiving sliding table 4, and the guiding and limiting seats 43 are in a trapezoidal structure.

[0044] The top ends of each group of limiting blocks 33 are connected with the same support arm 34 through a rotating shaft, and the bottom ends of the limiting blocks 33 are distributed in a semi-circular structure. When the guiding and limiting seat 43 moves towards the conveying table 3, the inclined surface of the guiding and limiting seat 43 abuts against the limiting block 33 and rotates successively until it abuts against the lower surface of the support arm 34, until the guiding and limiting seat 43 moves to both sides of the lithium battery stop frame, so that the receiving limiting structure and the limiting block 33 successfully complete the transposition work.

[0045] When the receiving sliding table 4 disengages from the conveying table 3, with the movement of the guiding and limiting seat 43, the limiting block 33 can be pulled by its own gravity to the original angle and is vertically distributed on both sides of the pallet 31 for facilitating the transportation of the stop frame again.

[0046] Embodiment 2: As Figures 4-7 shown, a U-shaped groove 331 is opened on the limiting block 33, and a first roller group 431 is provided at the top end of the guiding and limiting seat 43 at a position corresponding to the U-shaped groove 331. Both sides of the first roller group 431 are provided with second roller groups 432 that can rotate synchronously with it. 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 guiding and limiting seat 43 abuts against the limiting block 33 and rotates successively, the first roller group 431 moves within the U-shaped groove 331, and the second roller group 432 moves along the surface of the limiting block 33.

[0047] By combining the first roller group 431 and the second roller group 432 with the limit block 33 and the U-shaped groove 331 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.

[0048] 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. The conveying platform 3 and the receiving slide 4 can 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.

[0049] Example 3: As Figures 5-10 As shown in the figure, based on the first and second embodiments, 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 toward the end opposite to the second stop bar 42.

[0050] 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.

[0051] In order to make the stop gear plate 44 rotate smoothly, a shaft sleeve 441 is provided on the side of the stop gear plate 44 away from the second stop bar 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 positioning shaft 442 is provided.

[0052] 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 with it. 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. ​​​

[0053] A second lead screw slider 6 that can move along its conveying path is provided on the second conveyor belt 2. A first lead screw slider 5 that can move along the conveying path of the first conveyor belt 1 is provided on the second lead screw slider 6. A receiving slide table 4 is provided on the first lead screw slider 5. The second lead screw slider 6 can carry the first lead screw slider 5 and the receiving slide table 4 to move to the same path as the conveying table 3. Subsequently, the first lead screw slider 5 can drive the receiving slide table 4 to move towards the conveying table 3 until the receiving slide table 4 is docked with the conveying table 3.

[0054] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
