Description

Technical Field

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

[0002] Currently, the country is strongly advocating for new energy vehicles, and the lithium square battery industry has also developed significantly. Under these circumstances, the requirements for the production effect and efficiency of lithium square batteries are becoming increasingly stringent. Therefore, it is necessary to strengthen the effective control of battery production processes to improve the efficiency and capacity of production lines, which involves the battery tray transportation issue in battery sorting.

[0003] In existing battery pallet conveying mechanisms, battery pallets can only be conveyed along the length of the battery, not along the width. This makes it impossible to meet the needs of some applications that require rotating battery pallets to change the position of the battery when it leaves the production line, resulting in a limited range of production application scenarios. Utility Model Content

[0004] The main purpose of this utility model is to propose a battery tray conveying mechanism, which aims to solve the problem that the existing battery tray conveying mechanism has a single application scenario in battery tray production.

[0005] To achieve the above objectives, the battery tray conveying mechanism proposed in this utility model includes:

[0006] The lower frame is equipped with conveyor rollers for conveying battery trays;

[0007] A rotary lifting mechanism includes a mounting base, a lifting cylinder, a rotating base, a rotating top plate, and a drive assembly. The mounting base is mounted on the lower frame, the drive assembly is mounted on the mounting base, the rotating top plate is connected to multiple lifting shafts, and the rotating base is provided with multiple first linear bearings. The multiple lifting shafts are connected to the multiple first linear bearings in a one-to-one correspondence.

[0008] The telescopic rod of the lifting cylinder is connected to the rotating top plate, which lifts the battery tray. The driving assembly is used to drive the rotating base plate and rotate the rotating top plate.

[0009] Furthermore, the drive assembly includes a servo motor, a reducer, and a turntable bearing. The servo motor is driven and connected to the reducer. The output end of the reducer is driven and connected to an output gear. The teeth of the output gear mesh with the teeth of the turntable bearing. The inner ring of the turntable bearing is fixedly connected to the mounting base plate, and the outer ring of the turntable bearing is fixedly connected to the rotating base plate.

[0010] Furthermore, a first protective cover and a second protective cover are mounted on the mounting base plate. The first protective cover surrounds the outer periphery of the teeth of the output gear, and the second protective cover surrounds the outer periphery of the teeth of the turntable bearing.

[0011] Furthermore, the upper surface of the rotating top plate is covered with antistatic rubber.

[0012] Furthermore, a plurality of hydraulic buffers are provided between the rotating base plate and the rotating top plate.

[0013] Furthermore, the battery tray conveying mechanism also includes a lifting and blocking mechanism, which includes a blocking block, a blocking main board, a blocking sub-plate, a lower limit plate, a blocking main shaft, and a blocking cylinder. The blocking main board is mounted on the lower frame, and a second linear bearing is mounted on the blocking main board. The blocking main shaft passes through and connects to the second linear bearing, and its two ends are respectively connected to the blocking main board and the lower limit plate. The blocking cylinder is mounted on the blocking main board, and the extension rod of the blocking cylinder drives the blocking sub-plate, thereby causing the blocking sub-plate to drive the blocking block to block the conveying of the battery tray.

[0014] Furthermore, an anti-collision ring is also fitted around the outer periphery of the blocking spindle, and the anti-collision ring is located between the second linear bearing and the blocking sub-plate.

[0015] Furthermore, the main blocking plate is provided with a plurality of first buffers, the buffer heads of the first buffers being able to abut against the secondary blocking plate.

[0016] Furthermore, a limit block is provided on one side of the blocking motherboard relative to the lower limit plate, and a second buffer is provided on the lower limit plate, the buffer head of the second buffer being able to abut against the limit block.

[0017] Furthermore, limit stops are provided on both sides of the lower frame, and the distance between the limit stops on both sides is greater than the width of the battery tray and less than the length of the battery tray.

[0018] The limiting edges on both sides are respectively equipped with mutually cooperating infrared sensors. When the infrared rays emitted by the infrared sensors on both sides are blocked by the battery tray, the battery tray is conveyed through.

[0019] Compared with existing technologies, this utility model's technical solution involves placing a battery tray carrying the batteries on the conveyor rollers of a rotating roller mechanism during battery transport. After the battery tray reaches its designated position via the conveyor rollers, a lifting cylinder operates to push out a rotating top plate. A first linear bearing on the rotating base plate slides on the lifting shaft, detaching the battery tray from the conveyor rollers. Subsequently, a drive assembly drives the rotating base plate to rotate, which in turn drives the rotating top plate to rotate. This causes the battery tray on the rotating top plate to rotate to its designated position, changing the orientation of the batteries on the tray. Finally, the lifting cylinder operates again, causing the rotating top plate to descend, which in turn lowers the battery tray. The conveyor rollers then transport the battery tray to the next process. This configuration, through the combined use of the lifting cylinder and drive assembly, allows the battery tray to be turned on the transport line, meeting the needs of scenarios requiring changes in the battery tray's orientation and diversifying the production applications of the battery tray conveying mechanism.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 7 This utility model proposes a battery tray conveying mechanism.

[0030] The battery tray conveying mechanism includes a lower frame 100 and a rotary lifting mechanism 400. A conveying roller 210 is installed on the lower frame 100 for conveying the battery tray 300. The rotary lifting mechanism 400 includes a mounting base 410, a lifting cylinder 420, a rotating base 430, a rotating top plate 440, and a drive assembly 500. The mounting base 410 is installed on the lower frame 100, and the drive assembly 500 is installed on the mounting base 410. The rotating top plate 440 is connected to multiple lifting shafts 441. The rotating base 430 is provided with multiple first linear bearings 431. The multiple lifting shafts 441 are connected to the multiple first linear bearings 431 one by one. The telescopic rod of the lifting cylinder 420 drives the rotating top plate 440 to lift the battery tray 300. The drive assembly 500 is used to drive the rotating base 430 and drive the rotating top plate 440 to rotate.

[0031] Specifically, the lower frame 100 serves as the basic support component for supporting the rotary drum mechanism and the rotary lifting mechanism 400. Through the cooperation of the lifting shaft 441 and the first linear bearing 431, the rotary top plate 440 can move up and down relative to the rotary base plate 430, while the rotary base plate 430 rotates, driving the rotary top plate 440 to rotate as well. To protect the lifting cylinder 420 and extend its service life, in this embodiment, the end of the telescopic rod of the lifting cylinder 420 is connected to the rotary top plate 440 via a floating joint to absorb installation errors and eccentric loads in the mechanical connection. The battery tray 300 can hold batteries of various sizes or types. Taking a square battery as an example: when transporting batteries, the battery tray 300 carrying the batteries is placed on the conveyor roller 210 of the rotary roller mechanism. After the battery tray 300 is transported to the corresponding position by the conveyor roller 210, the lifting cylinder 420 operates to push out the rotating top plate 440. The first linear bearing 431 on the rotating base plate 430 slides on the lifting shaft 441, and the battery tray 300 is separated from the conveyor roller 210. Then, the drive assembly 500 drives the rotating base plate 430 to rotate, and the rotating base plate 430 further drives the rotating top plate 440 to rotate, so that the battery tray 300 on the rotating top plate 440 changes the placement direction of the batteries as it rotates to the corresponding position. Finally, the lifting cylinder 420 operates to lower the rotating top plate 440, thereby driving the battery tray 300 to lower. The conveyor roller 210 transports the battery tray 300 to the next process. With this configuration, the battery tray 300 can be turned on the transport line by using the lifting cylinder 420 and the drive component 500 together. This can meet the usage scenarios that require changing the placement direction of the battery tray 300, and make the production application scenarios of the battery tray conveying mechanism more diverse.

[0032] Please see Figure 5Furthermore, the drive assembly 500 includes a servo motor 510, a reducer 520, and a turntable bearing 530. The servo motor 510 drives and connects to the reducer 520. The output end of the reducer 520 is driven and connected to an output gear 531. The teeth of the output gear 531 mesh with the teeth of the turntable bearing 530. The inner ring 534 of the turntable bearing 530 is fixedly connected to the mounting base plate 410, and the outer ring 535 of the turntable bearing 530 is fixedly connected to the rotating base plate 430. Thus, the servo motor 510 increases the torque through the reducer 520, causing the output gear 531 to rotate. Since the inner ring 534 of the turntable bearing 530 is directly fixed to the mounting base plate 410, it remains stationary. The output gear 531 drives the turntable bearing 530, causing its outer ring 535 to rotate. Consequently, the outer ring 535 of the turntable bearing 530 drives the rotating base plate 430 to rotate, thereby enabling the rotating top plate 440 to drive the battery tray 300 to rotate. During the rotation of the rotating base plate 430 and the rotating top plate 440 driven by the servo motor 510, the rotating base plate 430, the rotating top plate 440, and the lifting cylinder 420 all rotate as a whole.

[0033] Please see Figures 4 to 5 To prevent dust contamination of the teeth of the output gear 531 and the turntable bearing 530, a first protective cover 532 and a second protective cover 533 are further installed on the mounting base plate 410. The first protective cover 532 surrounds the outer periphery of the teeth of the output gear 531, and the second protective cover 533 surrounds the outer periphery of the teeth of the turntable bearing 530. Thus, the first protective cover 532 and the second protective cover 533 protect the teeth of the output gear 531 and the turntable bearing 530, ensuring the meshing effect of the teeth of the output gear 531 and the turntable bearing 530, and guaranteeing the service life and stable operation of the entire rotary drive system.

[0034] Please see Figures 4 to 6 Furthermore, the upper surface of the rotating top plate 440 is covered with an antistatic rubber sheet 442. The antistatic rubber sheet 442 can prevent the battery tray 300 from slipping and can also provide insulation.

[0035] Please see Figures 4 to 6 Furthermore, multiple hydraulic buffers 443 are provided between the rotating base plate 430 and the rotating top plate 440. In this way, when the lifting cylinder 420 drives the rotating top plate 440 to descend, the hydraulic buffers 443 can buffer the rotating top plate 440, prevent the rotating top plate 440 from exerting a large force on the rotating base plate 430, and ensure the smooth operation of the entire lifting and rotating system.

[0036] Please see Figure 7Furthermore, the battery tray conveying mechanism also includes a lifting blocking mechanism 600. The lifting blocking mechanism 600 includes a blocking block 610, a blocking main plate 620, a blocking secondary plate 630, a lower limit plate 640, a blocking main shaft 650, and a blocking cylinder 660. The blocking main plate 620 is mounted on the lower frame 100, and a second linear bearing 621 is mounted on the blocking main plate 620. The blocking main shaft 650 passes through the second linear bearing 621 and connects to the blocking main plate 620 and the lower limit plate 640 at both ends, respectively. The blocking cylinder 660 is mounted on the blocking main plate 620, and the telescopic rod of the blocking cylinder 660 drives the blocking secondary plate 630, causing the blocking secondary plate 630 to drive the blocking block 610 to block the conveying of the battery tray 300. Specifically, the blocking main plate 620 and the blocking cylinder 660 are fixed, the blocking secondary plate 630 and the lower limit plate 640 are movable as a whole, and the blocking main shaft 650 can slide within the second linear bearing 621. As the battery tray 300 is about to be conveyed to the rotating top plate 440 via the conveyor roller 210, the blocking cylinder 660 operates, causing the blocking sub-plate 630 to push out the blocking block 610. The blocking block 610 can then stop the battery tray 300 from continuing to be conveyed and stop it on the rotating top plate 440. Then, the lifting cylinder 420 operates, causing the rotating top plate 440 to rise and the battery tray 300 to rise. The servo motor 510 increases the torque through the reducer 520 and outputs power to the output gear 531. The output gear 531 drives the outer ring 535 of the turntable bearing 530 to rotate, thereby driving the rotating base plate 430 to rotate. Through the first linear bearing 431 and the lifting shaft 441, the rotating top plate 440 is rotated. After the battery tray 300 has changed position, the blocking cylinder 660 drives the blocking sub-plate 630 to fall, causing the blocking block 610 to fall. The lifting cylinder 420 drives the rotating top plate 440 to fall, and the battery tray 300 continues to be placed on the conveyor roller 210. The battery tray 300 is then conveyed to the next process via the conveyor roller 210.

[0037] Please see Figure 7 Furthermore, an anti-collision ring 651 is fitted around the outer periphery of the blocking main shaft 650, and the anti-collision ring 651 is located between the second linear bearing 621 and the blocking sub-plate 630. In this way, the impact force of the blocking sub-plate 630 on the second linear bearing 621 and the blocking main plate 620 is buffered, ensuring structural stability. To protect the blocking cylinder 660 and extend its service life, in this embodiment, the end of the telescopic rod of the blocking cylinder 660 is connected to the blocking sub-plate 630 via a floating joint to absorb installation errors and eccentric loads in the mechanical connection.

[0038] Please see Figure 7Furthermore, the main blocking plate 620 is equipped with multiple first buffers 670, the buffer heads of which can abut against the secondary blocking plate 630. In this way, the first buffers 670 and the anti-collision ring 651 work together to provide a buffering effect, preventing the secondary blocking plate 630 from directly impacting the main blocking plate 620 and the second linear bearing 621, thus ensuring the service life of the structure.

[0039] Please see Figure 7 Furthermore, a limit block 680 is provided on one side of the blocking main board 620 relative to the lower limit plate 640, and a second buffer 690 is provided on the lower limit plate 640. The buffer head of the second buffer 690 can abut against the limit block 680. Specifically, the movement of the lower limit plate 640 is buffered by the limit block 680 and the second buffer 690, thereby limiting the movement stroke of the lower limit plate 640 and the blocking sub-plate 630, and preventing the blocking sub-plate 630 and the blocking block 610 from extending too far.

[0040] To ensure the battery tray 300 turn is completed, please refer to Figures 1 to 3 Furthermore, limit stops 700 are provided on both sides of the lower frame 100. The distance between the limit stops 700 is greater than the width of the battery tray 300 but less than the length of the battery tray 300. Thus, the width of a battery tray 300 can pass through the limit stops 700, but the length of a battery tray 300 cannot, ensuring that only the width of a battery tray 300 can pass through after the turn is completed. In this embodiment, infrared sensors can also be provided on the limit stops 700 on both sides, and the passage of the battery tray 300 can be determined by whether the infrared rays emitted by the infrared sensors on both sides are blocked by the battery tray 300, ensuring that the battery tray 300 can pass through after the turn is completed. For example, when the infrared rays emitted by the infrared sensors on both sides are blocked by the battery tray 300, it can be determined that the battery tray 300 has completed the turn and passed through.
