The device includes a frame, at least two parallel conveyor belts, a blocking mechanism, and a lifting and reversing mechanism. The lifting and reversing mechanism is positioned corresponding to each conveyor belt and can move up and down.

Description

Technical Field

[0001] This utility model relates to the field of industrial automation conveying technology, and in particular to a single-double conveying conversion device for a sagger conveying line in the production process of positive and negative electrode materials for lithium-ion batteries. Background Technology

[0002] The performance and cost of lithium-ion batteries largely depend on the manufacturing process of their positive and negative electrode materials. A crucial step in material preparation is filling powdered materials into saggers and then sintering them at high temperatures in a kiln. This process requires a highly efficient and continuous transportation system, as well as high reliability and flexibility, to meet the demands of modern production lines for increased cycle time and optimized layout.

[0003] Currently, on crucible conveyor lines, there are often situations where material transfer or process conversion needs to be performed between multiple parallel conveyor lines. For example, distributing crucibles from a main line to multiple parallel processing branch lines, or collecting processed crucibles from multiple branch lines to a main line.

[0004] In existing technologies, achieving this type of conversion function typically relies on the following methods:

[0005] Traditional right-angle steering gears or chain shift forks are used: these mechanisms are complex in structure, occupy a lot of space, and are prone to impacting the sagger during the conversion process, which may lead to uneven compaction of the powder in the sagger and affect the sintering quality.

[0006] Connecting multiple independent conveying devices to multiple drive sources: This method not only results in high equipment costs and complex control systems, but also increases the number of conversion links and potential failure points, thus reducing the overall reliability of the line.

[0007] Manual intervention or simple single-point lifting and translation mechanisms are inefficient and cannot meet the needs of automated continuous production. Furthermore, single-point lifting poses stability risks when transferring large or heavy crucibles, which can easily lead to jamming or overturning.

[0008] Therefore, there is an urgent need in this field for a specialized device that is compact, has a smooth and efficient conversion process, and can be integrated into existing parallel conveyor lines to achieve flexible switching between automated single and double conveyor modes. Utility Model Content

[0009] The purpose of this invention is to overcome the aforementioned deficiencies of the prior art and provide a single / double transport conversion device for a sagger transport line. This device enables smooth, efficient, and automated conversion of saggers between parallel transport lines, and is particularly suitable for improving the transport efficiency and reliability of lithium battery material sintering processes.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A single / double transport switching device for a crucible transport line includes: a frame, at least two parallel conveyor belts, a blocking mechanism, and a lifting and reversing mechanism.

[0012] The conveyor belt is mounted on the frame and is used to transport the saggers;

[0013] The blocking mechanism is located at the bottom of the conveyor belt to prevent the sagger from moving forward and to ensure its precise positioning.

[0014] The lifting and reversing mechanism is provided for each of the conveyor belts. The lifting and reversing mechanism can rise and fall to change the direction of the sagger from one conveyor belt to another.

[0015] Each of the lifting and reversing mechanisms includes multiple rows of reversing wheels, and the rotation direction of the reversing wheels is perpendicular to the rotation direction of the conveyor wheels of the conveyor belt.

[0016] Preferably, the adjacent lifting and reversing mechanisms are arranged in parallel and symmetrically, and can operate synchronously.

[0017] Preferably, the multiple rows of reversing wheels are arranged in parallel at intervals, and every two rows of reversing wheels are used to transport one sagger.

[0018] Preferably, each row of reversing wheels is provided with a reinforcing strip to provide support and enhance the overall structural rigidity during lifting and lowering.

[0019] Preferably, the height of the reversing wheel is configured such that when the lifting and reversing mechanism rises, the reversing wheel can receive and support the crucible, and disengage the crucible from the reinforcing bar.

[0020] Preferably, the lifting mechanism of the lifting and reversing mechanism includes a cylinder, which is mounted on the base plate of the frame and is used to drive the lifting and reversing mechanism to lift and lower.

[0021] Preferably, the reversing wheel is driven by a drive mechanism, which includes a motor, a sprocket, and a chain. The motor is connected to the sprocket of each row of reversing wheels through the sprocket and the chain.

[0022] Preferably, the drive mechanism further includes a transition sprocket mechanism, which includes multiple sprockets, at least one of which is a double-row sprocket; the output sprocket of the motor is connected to one row of the double-row sprockets of the transition sprocket mechanism via a chain.

[0023] Preferably, the sprockets of each row of reversing wheels are double-row sprockets; the double-row sprockets of multiple rows of reversing wheels on the same lifting and reversing mechanism are connected in series by chains; the side of the double-row sprockets of one row of reversing wheels that is not used for series connection is connected to the corresponding sprocket in the transition sprocket mechanism by chains.

[0024] Preferably, the sprockets of each row of reversing wheels are placed in the hollow cavity of the reinforcing strip.

[0025] Preferably, a sensor is provided on one side of the conveyor belt to detect the position of the sagger.

[0026] The beneficial effects of this utility model are as follows:

[0027] Compared with the prior art, the present invention has the following significant advantages:

[0028] 1. Efficient and smooth conversion: Through the linkage of lifting and reversing, the seamless conversion of the sagger between parallel conveyor lines is realized, which greatly reduces the transfer time and improves the production cycle.

[0029] 2. Stable and reliable operation: The use of multiple rows of reversing wheels to support and convey the sagger ensures uniform force distribution, avoids impact and vibration, guarantees the stability of the material inside the sagger, and improves product consistency.

[0030] 3. Compact and ingenious structure: The lifting and reversing mechanism is integrated inside the conveyor line, and the sprocket drive system is hidden in the reinforced bar cavity, which has a high space utilization rate and is easy to integrate into existing production lines.

[0031] 4. Simple and precise control: Through sensor positioning and coordinated control of cylinders and motors, fully automated and precise operation is achieved, reducing failure rate and labor costs.

[0032] 5. High scalability: The basic modular design of "single-double conversion" can be flexibly combined according to actual production needs to adapt to different production line layouts. Attached Figure Description

[0049] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0050] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0051] like Figure 1-3 As shown, a device for clamping multiple crucible lids in a single operation.

[0052] At least two parallel conveyor belts, a blocking mechanism, and a lifting and reversing mechanism.

[0053] The conveyor belt is mounted on the frame and is used to transport the saggers;

[0054] The blocking mechanism is located at the bottom of the conveyor belt to prevent the sagger from moving forward and to ensure its precise positioning.

[0055] The lifting and reversing mechanism is provided for each of the conveyor belts. The lifting and reversing mechanism can rise and fall to change the direction of the sagger from one conveyor belt to another.

[0056] Each of the lifting and reversing mechanisms includes multiple rows of reversing wheels, and the rotation direction of the reversing wheels is perpendicular to the rotation direction of the conveyor wheels of the conveyor belt.

[0057] See Figures 1 to 3 The present invention provides a single-double transport conversion device for a sagger transport line, which mainly includes a frame 1; two parallel conveyor belts, namely a first conveyor belt 2 and a second conveyor belt 3; a blocking mechanism and two lifting and reversing mechanisms, namely a first lifting and reversing mechanism 5 and a second lifting and reversing mechanism 6.

[0058] The first conveyor belt 2 and the second conveyor belt 3 are arranged parallel to each other on the frame 1 for use along a first direction (e.g., Figure 1 The conveyor belt (in the X direction) transports the crucible 100. The blocking mechanism is located at the bottom end of the conveyor belt. When the sensor (not shown in the figure) detects that the crucible 100 has reached the predetermined position, the blocking mechanism rises to prevent the crucible 100 from continuing to move forward.

[0059] The first lifting and reversing mechanism 5 and the second lifting and reversing mechanism 6 are respectively arranged corresponding to the first conveyor belt 2 and the second conveyor belt 3, and are arranged in parallel and symmetrically. Each lifting and reversing mechanism includes a lifting frame 8 driven by a cylinder 7. The cylinder 7 is fixed to the base plate of the frame 1.

[0060] The lifting frame 8 is equipped with multiple rows of parallel reversing wheels 9 arranged at intervals. The rotation direction of the reversing wheels 9 is perpendicular to the running direction of the conveyor belt (i.e., along the direction of rotation). Figure 1 (In the Y direction). A reinforcing strip 10 is provided next to each row of reversing wheels 9 to enhance the rigidity of the lifting frame 8. The highest point of the reversing wheel 9 is slightly higher than the upper surface of the reinforcing strip 10, ensuring that only the reversing wheel 9 contacts and lifts the crucible 100 when it is raised.

[0061] The reversing wheel 9 is driven by a drive mechanism. This drive mechanism includes a motor 11 and a transition sprocket mechanism 12. The transition sprocket mechanism 12 contains multiple sprockets, one of which is a double-row sprocket. The output sprocket of the motor 11 is connected to one row of this double-row sprocket via a chain.

[0062] Each row of reversing wheels 9 also has a double-row sprocket mounted on its shaft end. All double-row sprockets on the same lifting and reversing mechanism are connected in series by chains to form a linkage. The side of one row of double-row sprockets not used for series connection is connected to a corresponding sprocket on the transition sprocket mechanism 12 by a chain, thereby transmitting power to all reversing wheels 9. Preferably, these sprockets and chains are housed in the hollow cavity inside or on the side of the reinforcing bar 10, making the structure neat and protected.

[0063] Its workflow is as follows:

[0064] Initially, the first lifting and reversing mechanism 5 and the second lifting and reversing mechanism 6 are in the lowered position, and the first conveyor belt 2 and the second conveyor belt 3 are operating normally. When a conversion is required, the crucible 100 is conveyed to the conversion station, and the blocking mechanism rises to position it. Subsequently, the cylinders 7 of the two first lifting and reversing mechanisms 5 and the second lifting and reversing mechanism 6 are simultaneously lifted, and the reversing wheels 9 lift the crucible 100 from the conveyor belt. At the same time, the motor 11 starts, driving all the reversing wheels 9 to rotate synchronously, smoothly conveying the crucible 100 along the Y direction to the adjacent conveyor belt. After the transfer is completed, the first lifting and reversing mechanism 5 and the second lifting and reversing mechanism 6 descend, placing the crucible 100 on the target conveyor belt. The blocking mechanism descends, the target conveyor belt starts, and the crucible 100 is delivered, completing one work cycle. This process can realize the simultaneous and synchronous conversion of one or more crucibles 100.
