A power battery top cover plate feeding mechanism

Abstract

This application discloses a power battery top cover loading mechanism, belonging to the technical field of battery top cover loading equipment. It mainly includes: a belt conveyor and a lifting assembly installed at one end of the belt conveyor. The lifting assembly includes frames installed on both sides of the belt conveyor, each frame having a fixed plate, and each fixed plate having a support plate. This power battery top cover loading mechanism, through the arrangement of a positioning plate and a drag plate, ensures that when the drag plate drives the pallet downwards, the positioning plate remains in contact with the side of the pallet, providing stable lateral limiting through surface contact and ensuring the pallet's horizontal positional accuracy. When the pallet is conveyed to the belt conveyor, the extended portion of the positioning plate remains in contact with the side of the pallet until the pallet fully enters the conveyor belt's transmission channel, thereby effectively reducing displacement deviations caused by inertia or vibration during pallet transfer.

Description

Technical Field

[0001] This application relates to the technical field of battery top cover feeding equipment, specifically a feeding mechanism for a power battery top cover. Background Technology

[0002] In production and daily life, power batteries are widely used in new energy vehicles, energy storage systems and other applications due to their high energy density and long cycle life. During their production, the top cover plate, as a key component for battery encapsulation and electrical connection, needs to be installed precisely. The power battery top cover plate feeding mechanism, as an automatic feeding device on the production line, uses conveying components and positioning devices to orderly grab and transport the top cover plate to the designated workstation, precisely control the feeding process, and improve automation efficiency and assembly accuracy.

[0003] For example, patent CN209583054U discloses a feeding mechanism for a power battery top cover. This feeding mechanism includes a frame, a tray, a tray guide mechanism, a material support device, a conveying device, and a feeding device. This utility model can realize automatic feeding of power battery top covers, improve feeding efficiency, reduce labor intensity, and reduce labor costs.

[0004] In the battery top cover loading mechanism of the aforementioned patent, during the loading process, it is inconvenient to provide stable lateral limiting through surface contact during pallet transport and handover, which makes it difficult to ensure the positional accuracy of the pallet in the horizontal direction. As a result, the pallet is prone to displacement deviation due to inertia or vibration, affecting the accuracy of loading. Therefore, it is necessary to provide a power battery top cover loading mechanism to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a power battery top cover loading mechanism, which solves the problem of insufficient positional accuracy caused by the lack of surface contact lateral limiting during pallet conveying and handover, and the problem of displacement deviation caused by inertia or vibration, thus affecting the loading accuracy.

[0007] The technical solution adopted by this application to solve its technical problem is: a power battery top cover plate loading mechanism, comprising:

[0008] Belt conveyor;

[0009] A lifting assembly is installed at one end of the belt conveyor. The lifting assembly includes a frame installed on both sides of the belt conveyor. A fixing plate is installed on each frame, and a support plate is installed on each fixing plate on both sides. A large electric push rod is installed on the support plate, and an intermediate frame is installed at its output end.

[0010] A clamping assembly is mounted on the intermediate frame. The clamping assembly includes a small electric push rod. The output of the small electric push rod is equipped with a clamping plate. The intermediate frame is provided with a sliding groove. The clamping plate slides within the sliding groove. Positioning plates are vertically fixed at both ends of the clamping plate. The positioning plates adopt a through-type design, so that the lower end of the positioning plate passes through the clamping plate.

[0011] A feeding assembly is installed at one end of the belt conveyor and below the lifting assembly. The feeding assembly includes a medium-sized electric push rod whose output end extends to the upper part of the belt conveyor and is equipped with a slide plate.

[0012] Furthermore, the frame is configured in four groups and symmetrically installed on both sides of the belt conveyor.

[0013] Furthermore, guide rails are installed on all the fixed plates, and guide blocks are installed at both ends of the intermediate frame, with the guide blocks closely cooperating with the guide rails.

[0014] Furthermore, at least two sets of limiting blocks are installed in the slide groove, and the clamping plate is provided with limiting grooves that match the shape of the limiting blocks.

[0015] Furthermore, the clamping plate is made of 45# steel.

[0016] Furthermore, the contact surface between the clamping plate and the tray is equipped with an anti-slip cushioning pad.

[0017] Furthermore, the positioning plate is in the shape of a flat cuboid.

[0018] The beneficial effects of this application are as follows: The power battery top cover loading mechanism provided by this application, through the setting of positioning plate and slide plate, when the slide plate drives the pallet to be conveyed downward, the positioning plate always keeps in contact with the side of the pallet, and provides stable lateral limit through surface contact, ensuring the positional accuracy of the pallet in the horizontal direction. When the pallet is conveyed to the belt conveyor, the extended part of the positioning plate still keeps in contact with the side of the pallet until the pallet is completely in the conveying channel of the conveyor belt, thereby effectively reducing the displacement deviation of the pallet caused by inertia or vibration during the handover process.

[0019] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. A further detailed description of this application will be provided below with reference to the figures. Attached Figure Description

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0032] like Figure 1 and Figure 3 As shown, this application provides a power battery top cover loading mechanism, including a belt conveyor 1, on which a first tray 5 for storing battery top covers is conveyed, forming a conveying channel for the first tray 5.

[0033] like Figures 1-4 and Figure 6 As shown, a lifting assembly 2 is installed at one end of the belt conveyor 1. The lifting assembly 2 is used to support multiple second trays 6 for storing battery top covers. The lifting assembly 2 includes a frame 21 welded and fixed to the belt conveyor 1. The frame 21 is configured as four sets and symmetrically welded to both sides of the belt conveyor 1 (two sets on each side) to form a stable support structure that can withstand the multiple loads of the second trays 6 and battery top covers.

[0034] Fixed plates 22 are bolted to the frame 21. These fixed plates 22 serve as the support for the lifting assembly 2. They are made of high-strength alloy steel plates, providing a stable foundation support for the entire lifting assembly 2. Support plates 23 are fixedly installed at adjacent ends of the upper part of the fixed plates 22 on both sides. These support plates 23 are made of thickened steel to further enhance the structural rigidity. Large electric push rods 24 are securely installed on the support plates 23 by bolts. These large electric push rods 24 have displacement control and thrust output functions. Their output ends are fixedly connected to the intermediate frame 25 by bolts. The intermediate frame 25 is used to support the weight of multiple second trays 6 and the battery top cover. During operation, the large electric push rods 24 are powered by an external power supply and start under the command of the corresponding controller. They adjust the thrust according to the preset program and push the intermediate frame 25 to rise and fall smoothly in the vertical direction, thereby adjusting the height of the second trays 6 on it and ensuring the connection accuracy between the second trays 6 and the belt conveyor 1.

[0035] To ensure the stability and accuracy of the lifting process of the intermediate frame 25, guide rails 26 are bolted to the fixed plate 22. The guide rails 26 are linear slide rails. Guide blocks 27 are bolted to both ends of the intermediate frame 25. The guide blocks 27 are tightly fitted with the guide rails 26 and can slide stably on them, effectively limiting the shaking of the intermediate frame 25. This keeps the second tray 6 horizontal during the lifting process, reduces the occurrence of damage to the battery top cover due to tilting and shaking, and improves the reliability of equipment operation.

[0036] like Figures 1-4 and Figure 7 As shown, a clamping assembly 3 is installed on the intermediate frame 25. The clamping assembly 3 contacts and provides support to multiple stacked second pallets 6, improving the stability of the second pallets 6 during lifting and conveying. The clamping assembly 3 includes a fixing frame 31 installed on the lower end face of the intermediate frame 25. The fixing frame 31 is welded from Q345B high-strength steel plate and is installed with the intermediate frame 25 by countersunk bolts to form a stable basic support structure. A small electric push rod 32 is bolted to the fixing frame 31. The small electric push rod 32 has flexible driving performance, and its installation position is calibrated to ensure that the direction of the push force is consistent with the clamping requirements of the second pallet 6.

[0037] The upper surface of the intermediate frame 25 is provided with a sliding groove 33. The sliding groove 33 is milled and has a smooth and flat surface. The output end of the small electric push rod 32 is bolted to a clamping plate 34 that slides within the sliding groove 33. The bottom of the clamping plate 34 forms a sliding fit with the sliding groove 33. When the small electric push rod 32 is started, the thrust at the output end is directly transmitted to the clamping plate 34, allowing it to slide smoothly within the sliding groove 33. The clamping plate 34 is made of quenched 45# steel, which has high hardness and wear resistance. Its contact surface with the second tray 6 is also covered with an anti-slip buffer pad (not shown in the figure). When it abuts against the two sides of the bottom second tray 6, it can provide sufficient friction to reduce tray slippage and reduce rigid contact damage to the tray.

[0038] Positioning plates 37 are vertically fixed at both ends of the clamping plate 34. The positioning plates 37 are flat cuboids with a through-type design, so that the lower end of the positioning plates 37 passes through the clamping plate 34 and extends downward to form a stable positioning support structure. The part of the positioning plates 37 located below the clamping plate 34 is specifically used to position the first pallet 5. After fine grinding and polishing, the surface of the positioning plates 37 can fit against the sides of the first pallet 5 and the second pallet 6, providing stable position limit through surface contact. This effectively reduces the risk of lateral displacement of the second pallet 6 during stacking and lifting. At the same time, it ensures the accuracy of the position of the first pallet 5 before it is conveyed on the belt conveyor 1, reducing the risk of battery top cover falling off or equipment malfunction due to position displacement.

[0039] At least two sets of limiting blocks 35 are fixed in the slide groove 33. The clamping plate 34 is provided with a limiting groove 36 that matches the shape of the limiting block 35. When the small electric push rod 32 drives the clamping plate 34 to slide in the slide groove 33, the limiting groove 36 on the clamping plate 34 will slide on the outer wall of the limiting block 35, which further improves the stability of the clamping plate 34 during the movement.

[0040] like Figure 3 , Figure 5 and Figure 6 As shown, a feeding assembly 4 is installed at one end of the belt conveyor 1 and below the lifting assembly 2. The feeding assembly 4 is used to place the second pallet 6 on the belt conveyor 1 in sequence and to transport the second pallet 6 through linear motion control. The feeding assembly 4 includes a frame 41 fixed to one end of the belt conveyor 1. The frame 41 serves as the basic frame of the entire assembly. A medium-sized electric push rod 42 is horizontally installed on the frame 41 by bolts. The medium-sized electric push rod 42 has the ability to output thrust and control displacement. Its output end can be flexibly extended and retracted according to the command. Its output end can extend to the upper part of the belt conveyor 1 and a slide plate 43 is installed by high-strength bolts. The surface of the slide plate 43 is provided with anti-slip texture (not shown in the figure). It can connect to the bottom second pallet 6 and transport it smoothly to the belt conveyor 1.

[0041] On both sides of the frame 41, two sets of connecting plates 44 are welded and fixed. Each set of connecting plates 44 is vertically fixed with a guide rod 45. The guide rod 45 adopts a high-precision ground linear optical axis and the surface is hardened to have excellent wear resistance. The lower end face of the slide plate 43 is symmetrically fixed with guide sleeves 46. The guide sleeves 46 and the guide rods 45 form a sliding fit. When the medium-sized electric push rod 42 drives the slide plate 43 to move, the guide sleeves 46 slide smoothly along the guide rods 45, effectively limiting the swaying and deviation of the slide plate 43, ensuring that the second pallet 6 remains horizontal during the conveying process and is accurately placed at the designated position of the belt conveyor 1, providing a reliable guarantee for the stable conveying of subsequent pallets.

[0042] Working principle: During the feeding stage, the belt conveyor 1 is first kept stationary. At this time, the medium-sized electric push rod 42 extends under the command of the control system, driving the slide plate 43 to move along the guide rod 45 towards the lifting assembly 2. The anti-slip texture on the surface of the slide plate 43 connects with the second tray 6 at the bottom of the lifting assembly 2.

[0043] After docking is completed, the small electric push rod 32 retracts under the command of the control system, causing the clamping plate 34 to slide in the slide groove 33 and release the clamping of the bottom second tray 6. Then, the large electric push rod 24 is activated, driving the clamping assembly 3 to move upward by the height of one tray until the clamping plate 34 rises to the side position of the new bottom second tray 6. Subsequently, the small electric push rod 32 is activated again, causing the clamping plate 34 to clamp the new bottom second tray 6, while the positioning plate 37 is once again in contact with the side position of the second tray 6.

[0044] Subsequently, the medium-sized electric push rod 42 retracts, driving the slide plate 43 to move along the guide rod 45 towards the belt conveyor 1, smoothly conveying the lowermost second pallet 6 onto the upper conveyor belt of the belt conveyor 1. At the same time, the large electric push rod 24 is controlled to reset the clamping assembly 3. During this process, the lower end of the positioning plate 37 penetrates the positioning structure formed by the clamping plate 34, and it always remains in contact with the side of the second pallet 6 as the slide plate 43 drives the pallet downward. The surface contact provides stable lateral limiting, ensuring the positional accuracy of the pallet in the horizontal direction. When the pallet is conveyed to the belt conveyor 1, the extended part of the positioning plate 37 still maintains contact with the side of the pallet until the pallet is completely in the conveyor belt's transmission channel, thereby effectively reducing the displacement deviation of the pallet caused by inertia or vibration during the handover process. The belt conveyor 1 is restarted to realize the loading process of the battery top cover.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. 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 protection scope of this application.
