[0033] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0034] Reference Figure 1 , Figure 2 A rotating unit includes a rotating platform 100 and a rotating disk 300, the rotating disk 300 being rotatably mounted on the rotating platform 100; a first motor 400 for driving the rotating disk 300 to rotate relative to the rotating platform 100; a roller conveyor assembly 500 mounted on the rotating disk 300; a second motor 600 for driving the conveyor roller 510 of the roller conveyor assembly 500 to rotate to convey goods; and a positioning assembly 700 including a positioning photoelectric sensor 710 fixedly mounted on the rotating platform 100 and a position marker 720 mounted on the rotating disk 300, the positioning photoelectric sensor 710 cooperating with the position marker 720 to detect the angular position of the rotating disk 300; when the first motor 400 drives the rotating disk 300 to rotate to a preset angular position, the positioning photoelectric sensor 710 detects the position marker 720 and controls the rotating disk 300 to stop rotating, thereby adjusting the direction of goods conveying.

[0035] The rotating unit adjusts the direction of cargo conveying through the cooperative structure of the rotating table 100 and the rotating disk 300. When the rotating disk 300 rotates, the roller conveyor assembly 500 also rotates, thereby changing the direction of cargo conveying. The second motor 600 drives the conveyor rollers 510 in the roller conveyor assembly 500 to rotate to ensure continuous conveying of goods during the conveying process. Furthermore, the positioning component 700 detects the angular position of the rotating disk 300 by cooperating with the positioning photoelectric sensor 710 fixedly mounted on the rotating table 100 and the position marker 720 mounted on the rotating disk 300. When the first motor 400 drives the rotating disk 300 to rotate to the preset angular position, the positioning photoelectric sensor 710 detects the position marker 720 and sends a control signal to stop the rotating disk 300 from rotating. For example, in the application scenario of the new energy battery cell production line, when the battery cell needs to be transferred from the main conveyor line to branch A to enter the formation process, the first motor 400 drives the rotating disk 300 to rotate 90 degrees. At this time, the positioning photoelectric sensor 710 detects the corresponding position marker 720 and controls the rotating disk 300 to stop rotating. Then, the second motor 600 drives the conveyor roller 510 to rotate and transport the battery cell tray to branch A.

[0036] In some embodiments, refer to Figure 2 , 3 A gear disk 200 is provided between the rotary table 100 and the rotary disk 300. The gear disk 200 and the rotary disk 300 are coaxially and fixedly connected, and the gear disk 200 is rotatably connected to the rotary table 100. The first motor 400 is fixedly mounted on the rotary table 100. The output shaft of the first motor 400 is provided with a drive gear 410. The drive gear 410 meshes with the teeth of the gear disk 200 for transmission. The rotation of the drive gear 410 drives the gear disk 200 and the rotary disk 300 to rotate synchronously.

[0037] To improve transmission efficiency and accuracy, a gear disk 200 is provided as an intermediate transmission component between the rotary table 100 and the rotary disk 300. The gear disk 200 and the rotary disk 300 are coaxially fixedly connected to ensure that they can rotate synchronously without relative displacement. At the same time, the gear disk 200 is rotatably connected to the rotary table 100, allowing the gear disk 200 to rotate freely on the rotary table 100. The first motor 400 is fixedly mounted on the rotary table 100, and a drive gear 410 is provided on the output shaft of the first motor 400 as the power output end. When the first motor 400 starts, the drive gear 410 starts to rotate and transmits the rotational torque to the gear disk 200 through gear meshing. Since the gear disk 200 and the rotary disk 300 are coaxially fixedly connected, the rotation of the gear disk 200 directly drives the rotary disk 300 to rotate synchronously.

[0038] Furthermore, refer to Figure 2A speed-changing assembly 420 is provided between the output shaft of the first motor 400 and the drive gear 410. The speed-changing assembly 420 includes an input end and an output end. The input end is connected to the output shaft of the first motor 400, and the output end is connected to the drive gear 410. The speed-changing assembly 420 is used to adjust the output speed of the first motor 400 to control the rotational speed and accuracy of the rotating disk 300. The speed-changing assembly 420 uses an internal gear reduction or speed-increasing mechanism to adjust the output speed of the first motor 400, thereby controlling the rotational speed and accuracy of the rotating disk 300 to meet the needs of different working conditions. When the first motor 400 outputs high-speed rotation, the speed-changing assembly 420 reduces the speed and transmits it to the drive gear 410, so that the drive gear 410 drives the gear disk 200 and the rotating disk 300 to rotate at a lower speed. This can achieve better angle control accuracy and smoother rotation.

[0039] In some embodiments, refer to Figure 2 , 3 The rotating platform 100 is provided with multiple fixing plates 110. The fixing plates 110 are arc-shaped and distributed circumferentially along the rotating platform 100. Each fixing plate 110 is used to install the positioning photoelectric sensor 710. The multiple positioning photoelectric sensors 710 respectively detect different angular positions on the rotating disk 300 to achieve multi-position positioning of the rotating disk 300. The multiple positioning photoelectric sensors 710 respectively detect position markers 720 at different angular positions on the rotating disk 300, thereby realizing multi-position positioning control of the rotating disk 300. When the rotating disk 300 rotates, the position markers 720 at different angular positions will pass through the detection range of the corresponding positioning photoelectric sensor 710 in sequence. When each positioning photoelectric sensor 710 detects the corresponding position marker 720, it will send a signal to control the rotating disk 300 to stop rotating at that angular position.

[0040] Specifically, the positioning photoelectric device 710 in this case is a U-shaped switch, and the position marker 720 is a light-blocking plate. On the arc-shaped fixed plate 110, the position of the U-shaped switch relative to the fixed plate 110 can be adjusted so that the detection beam path of the U-shaped switch corresponds to the movement trajectory of the light-blocking plate on the rotating disk 300. When the rotating disk 300 rotates, the light-blocking plate enters the detection slot of the U-shaped switch to block the beam from triggering the detection signal. By adjusting the radial and angular positions of the U-shaped switch on the fixed plate 110, it can adapt to the installation requirements of rotating disks 300 of different specifications and ensure that the light-blocking plate can accurately enter the detection range of the U-shaped switch. At the same time, by fine-tuning the position of the U-shaped switch, machining and assembly errors can be compensated, thereby improving the reliability and repeatability of positioning detection.

[0041] In some embodiments, refer to Figure 3 , 4The rotating table 100 is provided with at least two first limiting blocks 120, and the rotating disk 300 is provided with a second limiting block 310. The second limiting block 310 contacts the first limiting block 120 during the rotation of the rotating disk 300 to limit the rotation angle range of the rotating disk 300. Specifically, the first limiting blocks 120 and the second limiting block 310 limit the rotational movement of the rotating disk 300 within a preset angle range, preventing the rotating disk 300 from exceeding its designed working area and damaging the equipment or affecting sorting accuracy. Adjusting the curvature between the two first limiting blocks 120 allows for adjustment of the rotatable angle range of the rotating disk 300 to meet the needs of different sorting outlet numbers and angle configurations. Since the two first limiting blocks 120 and the second limiting block 310 are located on the same motion trajectory, the second limiting block 310 can sequentially contact the two first limiting blocks 120 during the rotation of the rotating disk 300, achieving a bidirectional limiting protection function. Specifically, the curvature between the two first limit blocks 120 can be adjusted according to requirements.

[0042] Furthermore, a buffer 130 is provided on the first limiting block 120. The buffer 130 is located on the contact surface between the first limiting block 120 and the second limiting block 310, and is used to provide buffer protection when the second limiting block 310 contacts the first limiting block 120. Specifically, the buffer 130 is a rubber pad or a polyurethane elastomer, which has good elastic deformation capability and energy absorption characteristics. When the rotating disk 300 rotates to its limit position, the second limiting block 310 contacts the first limiting block 120. The buffer 130 can absorb the impact energy and reduce the contact impact force, avoiding damage to the limiting block and rotating mechanism caused by hard collision. At the same time, the buffer 130 can also reduce the noise and vibration generated by the collision, and improve the stability of equipment operation and service life.

[0043] In some embodiments, refer to Figure 1 , 2 The roller conveyor assembly 500 includes multiple conveyor rollers 510, which together form a conveying channel 520. A fixed blocking member 530 is provided at the bottom end of the conveying channel 520, and a movable blocking member 540 is provided at the open end of the conveying channel 520. The movable blocking member 540 is mounted on the rotating disk 300 and is raised and lowered by a cylinder. In use, the movable blocking member 540 is in a retracted state, that is, it descends to a position below the surface of the conveyor rollers 510, allowing goods to enter from the open end. Once the goods are fully inside the conveying channel 520, the movable blocking member 540 rises, confining the goods within the conveying channel 520 and preventing them from slipping or shifting from the open end during rotation. After the goods have rotated to their designated position, the movable blocking member 540 descends, and the conveyor rollers 510 deliver the goods out.

[0044] Furthermore, entry sensors 550 are respectively installed on both sides of the opening end of the conveying channel 520 to detect the entry and exit of materials into the conveying channel 520; a position sensor 560 is installed at the bottom end of the conveying channel 520 to detect when the material reaches the position of the fixed blocking member 530 and trigger a change in the conveying direction. Specifically, the entry sensors 550 are through-beam photoelectric sensors, installed on the left and right sides of the opening end of the conveying channel 520 to form a detection beam spanning the entire width of the channel. When goods enter, the goods block the detection beam of the entry sensor 550, causing a signal change. The system recognizes the entry status of the goods and starts the conveyor roller 510 to rotate forward to transport the goods to the bottom end of the channel. After entering, and when the position sensor 560 detects that the goods have reached the position of the fixed blocking member 530, the movable blocking member 540 rises, and at the same time, the conveyor roller 510 stops rotating or starts to rotate in reverse to prepare to send the goods back to the opening end. If it is necessary to change the conveying direction of the goods, the first motor 400 drives the rotating disk 300 to rotate to the target angle.

[0045] In some embodiments, a gear is provided at the end of the conveyor roller 510, and the second motor 600 is connected to the gear via a chain to drive the conveyor roller 510 to rotate, thereby realizing the conveying of materials within the conveying channel 520. It is understood that by cooperating with the gears of multiple conveyor rollers 510 via a chain, synchronous driving and unified control of multiple conveyor rollers 510 are achieved. A drive sprocket is provided on the output shaft of the second motor 600, and the chain sequentially passes around the gear at the end of each conveyor roller 510 to form a closed transmission circuit. When the second motor 600 starts, the drive sprocket drives the chain to move, and the movement of the chain is transmitted to each conveyor roller 510 through the gears, causing them to rotate synchronously. Since all conveyor rollers 510 are connected via the same chain, the consistent speed and direction of rotation of each conveyor roller 510 can be ensured, ensuring smooth conveying of goods within the conveying channel 520 without any jamming or deviation caused by speed differences.

[0046] Reference Figure 5A rotating mechanism includes: a frame 800, a protective cover assembly 900, and a plurality of the aforementioned rotating units; the plurality of rotating units are fixedly connected to the frame 800; the protective cover assembly 900 is disposed around the plurality of rotating units to provide safety protection; the plurality of rotating units can be installed vertically or horizontally on the frame 800. It is understood that the rotating mechanism of this invention is obtained by mounting multiple rotating units in an array on the frame 800. Specifically, different numbers of rotating units can be configured as needed, and vertical or horizontal installation methods can be selected to adapt to different site layouts and sorting requirements. When vertical installation is adopted, the multiple rotating units are vertically arranged on the frame 800 to form a three-dimensional sorting structure, which can make full use of vertical space to improve the sorting capacity per unit area. When horizontal installation is adopted, the multiple rotating units are horizontally arranged to facilitate loading and unloading operations and equipment maintenance. The protective cover assembly 900 surrounds the multiple rotating units to form a closed safety protection area, preventing operators from accidentally entering the moving parts area and blocking dust and debris from entering the equipment. For example, in express sorting applications, two rotating units can be vertically installed on the frame 800 to form a two-layer sorting structure, which greatly improves sorting efficiency and space utilization. The protective cover assembly 900 is equipped with a transparent observation window to facilitate operators to monitor the equipment's operating status, and is also equipped with a safety door lock and an emergency stop button to ensure operational safety.
