Description

Technical Field

[0001] This utility model relates to the technical field of lithium-ion battery material production equipment, specifically to a sagger with multiple gaps for reversing and transferring loads. Background Technology

[0002] In the production process of positive and negative electrode materials for lithium-ion batteries, powdered materials need to be placed in saggers and sintered at high temperatures in a kiln. The saggers require conveying, positioning, grouping, and reversing operations at the kiln's inlet and outlet ends and at process junctions. Currently, existing sagger conveying systems typically have the following shortcomings:

[0003] First, the grouping function lacks flexibility. Different production processes have different requirements for the spacing of saggers in the kiln, such as sintering in groups of one, two, or three saggers. Existing equipment mostly uses push rods or blocks with fixed spacing for grouping, which cannot quickly and easily adapt to various changes in grouping spacing. This results in low equipment versatility, requiring machine shutdown and complex mechanical adjustments when switching production modes, which seriously affects production efficiency.

[0004] Secondly, the structural design is not adaptable enough to the production environment. Battery materials are mostly fine dust, which can easily penetrate the moving parts and complex mechanisms of the equipment, leading to failures such as transmission jamming, sensor malfunction, and accelerated wear, resulting in low equipment reliability and high maintenance frequency.

[0005] Secondly, in terms of functional integration, existing conveyor lines are limited in function. They often require multiple independent devices and multiple positioning and transfer operations to complete grouping and reversal operations, resulting in problems such as large footprint, low connection efficiency, and complex control systems.

[0006] Therefore, there is an urgent need in this field for a crucible transfer device that can flexibly adapt to various grouping gap requirements, has a simple and reliable structure, can adapt to dusty environments, and can efficiently integrate conveying, grouping and reversing functions. Utility Model Content

[0007] In view of the above-mentioned shortcomings of the prior art, the core technical problem to be solved by this utility model is: how to provide a crucible transfer device that can flexibly and conveniently realize the adjustment of various group gaps, while having a simple and reliable overall structure, effectively resisting the adverse effects of dusty environments, and integrating efficient reversing functions.

[0008] Technical solution of this utility model

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0010] A sagger-type reversing and transfer device with multiple clearances includes:

[0011] The main conveyor line includes two rows of first conveyor wheels arranged in parallel for conveying the crucibles along a first direction, and the end of the main conveyor line is provided with a hard stop.

[0012] A lifting mechanism is provided below the main conveyor line and between the two rows of the first conveyor wheels. It is used to lift a group of crucibles as a whole to detach them from the first conveyor wheels after the crucibles are positioned by the hard block.

[0013] The lifting mechanism includes a lifting driver, a lifting plate driven by the lifting driver, and a plurality of support plates adjustablely mounted on the lifting plate through oblong holes; by adjusting the fixed position of the support plates in the oblong holes, the spacing between adjacent support plates can be changed.

[0014] Each of the support plates is fixed with a plastic plate on top, and each support plate is also provided with a blocking wheel;

[0015] A reversing conveyor line is located above one side of the main conveyor line and is used to receive and convey the sagger assembly that has been lifted to a predetermined height by the lifting mechanism in a second direction.

[0016] Furthermore, the plastic sheet has horizontally outwardly extending protrusions.

[0017] Furthermore, the height of the plastic plate is higher than the height of the blocking wheel.

[0018] Furthermore, the lifting driver is a cylinder, and the lifting plate is guided by guide rods set at the four corners and linear bearings.

[0019] Furthermore, photoelectric sensors for detecting the positioning of the saggers are installed on both sides of the main conveyor line.

[0020] Furthermore, the lifting mechanism is mounted on a lifting platform.

[0021] Furthermore, the lifting platform is a third conveyor line, which includes multiple rows of third conveyor wheel sets arranged along the second direction; the support plate extends through the gap between adjacent third conveyor wheel sets when it is lifted.

[0022] Furthermore, an overall lifting device is provided below the third conveyor line to drive the third conveyor line and the lifting mechanism mounted on it to lift as a whole.

[0023] Furthermore, the overall lifting device uses a synchronous lifter to achieve synchronous lifting at four points.

[0024] Furthermore, each of the support plates is provided with two parallel waist-shaped holes, which are locked to the lifting plate by screws.

[0025] Beneficial effects of this utility model

[0026] Compared with the prior art, the sagger reversing and transfer device with multiple gaps provided by this utility model has the following significant advantages:

[0027] 1. Flexible and adjustable group spacing, strong versatility: The simple oblong hole connection between the support plate and the lifting plate enables stepless or stepped adjustment of the spacing between adjacent support plates. Operators only need to loosen the screws, move the support plate, and re-tighten it to quickly configure the device into various working modes such as "single bowl spacing 10mm", "double bowl spacing 25mm", or "triple bowl spacing 50mm", perfectly adapting to different process requirements and greatly improving the equipment's versatility and production flexibility.

[0028] 2. Simple and reliable structure, adaptable to harsh environments: The entire lifting and grouping mechanism has few moving parts and direct transmission. It adopts cylinder drive and guide rod guidance, resulting in a stable structure. In particular, it avoids the use of complex electric push rods, servo systems, or precision linkage mechanisms, reducing the risk of malfunctions due to dust intrusion from the source. It is very suitable for long-term stable operation in the dusty environment of lithium battery material production.

[0029] 3. Highly integrated functions and efficient space utilization: This invention integrates multiple functions such as linear conveying, precise positioning, grouping intervals, and vertical reversal into a compact workstation. Through the ingenious combination of the lifting mechanism and the third conveyor line, a smooth transition of the crucible assembly between the main conveyor line and the reversing conveyor line is achieved, reducing transfer links, improving overall production efficiency, and saving equipment floor space.

[0030] 4. Optimized design details ensure stable and precise operation: The horizontal raised design on the plastic plate increases the contact area with the bottom of the crucible, improving stability during the lifting process. The design of the plastic plate being higher than the blocking wheels ensures that the crucible is lifted smoothly during lifting, while the rear blocking wheels effectively prevent spillage and create a precise gap. The third conveyor line uses four-point synchronous lifting to ensure the smoothness and synchronization of the lifting of long-length conveyor units, preventing the crucible assembly from tipping over during transfer.

[0055] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0056] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0057] like Figures 1 to 4 As shown, the present invention provides a multi-gap reversing and transfer device for a sagger, which mainly includes a main conveyor line 1, a lifting mechanism 2, and a reversing conveyor line 3.

[0058] The main conveyor line 1 is driven by a motor to rotate two rows of parallel first conveyor wheels 11, used for conveying along... Figure 1-2The crucible 100 is conveyed in the X direction. A hard stop 12 is provided at the end of its conveying. Detection photoelectric sensors 13 are installed on both sides of the main conveyor line 1 to detect whether the crucible 100 is in place.

[0059] The lifting mechanism 2 is located below the main conveyor line 1, specifically in the space between the two rows of first conveyor wheels 11. The lifting mechanism 2 mainly includes a lifting driver 21, a lifting plate 22, and a support plate 23. The lifting driver 21 is a cylinder used in this embodiment. The lifting plate 22 is driven by the cylinder and guided by guide rods 24 at the four corners and linear bearings 25 to achieve stable vertical lifting.

[0060] The support plate 23 is adjustablely mounted on the lifting plate 22 via two parallel oblong holes 231 using screws. By loosening the screws, the support plate 23 can be moved back and forth, thereby adjusting the spacing L between adjacent support plates 23 to accommodate different grouping requirements (such as three bowls per group, two bowls per group, etc.). After adjustment, the screws are tightened to secure it. A plastic plate 233 is fixed to the top of each support plate 23. This plastic plate 233 has horizontally outwardly extending protrusions 2331 to increase the contact area with the bottom of the sagger 100. A stop wheel 234 is also installed on the support plate 23. Crucially, the top surface height H1 of the plastic plate 233 is designed to be higher than the top height H2 of the stop wheel 234. This design ensures that during lifting, the plastic plate 233 first contacts and supports the bottom of the sagger 100, lifting it up, while the stop wheel 234, after being fully lifted, is positioned high enough to block subsequent saggers 100, thus creating a grouping gap.

[0061] The lifting mechanism 2 is installed as a whole on a lifting platform, namely the third conveyor line 4. The third conveyor line 4 includes multiple rows along the second direction ( Figure 3 The third conveyor wheel set 41 is set in the Y direction. During lifting, the support plate 23 passes through the gap between adjacent third conveyor wheel sets 41. An overall lifting device 5 is provided below the third conveyor line 4. In this embodiment, a synchronous lifter is used to achieve stable lifting at four points, which is used to lift or lower the entire third conveyor line 4 and its lifting mechanism 2 together.

[0062] The reversing conveyor line 3 is located above one side of the main conveyor line 1, and in this embodiment it is the second conveyor belt.

[0063] The working process of this utility model is as follows:

[0064] The sagger 100 is conveyed via the main conveyor line 1 until it is stopped and precisely positioned by the hard stop 12. After the photoelectric sensor 13 confirms that a group of saggers 100 (e.g., three) is in place, the lifting driver 21 is activated, driving the lifting plate 22 and all support plates 23 to rise. The support plates 23 pass through the gap between the first conveyor wheels 11, and the plastic plates 233 on them lift the group of saggers 100 as a whole, detaching them from the first conveyor wheels 11. During the lifting process, the rear saggers 100 are blocked by the raised stop wheel 234, thus creating the required gap between this group of saggers 100 and the subsequent saggers 100. Subsequently, the group of saggers 100 is lowered to the conveying position of the third conveyor line 4, which is flush with the rear saggers 100. Then, the overall lifting device 5 is activated, lifting the group of saggers on the third conveyor line 4 together until the bottom of the saggers 100 is flush with the conveying surface of the reversing conveyor line 3. Next, the third conveyor wheel group 41 of the third conveyor line 4 starts, sending the sagger assembly out along the Y direction, completing the reversing transfer. After the transfer is completed, each mechanism resets in reverse order, preparing for the next work cycle.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
