Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a shell pressing device for battery casting and welding. Background Art

[0002] A storage battery is composed of a battery case, a plate group and a bus bar. During the production process, the plate group needs to be sorted and pressed through a mold, and then pressed into the battery case by a downward pressing mechanism. After the shell pressing is completed, the storage battery enters the casting and welding working area through a production line to be welded with the bus bar.

[0003] For the existing shell pressing device for battery casting and welding, workers need to manually press the plate group with a mold, then place the mold and the battery case on the downward pressing mechanism for shell pressing, and after the shell pressing is completed, carry the semi-finished product to the production line for output. Since workers need to put their hands into the working area of the downward pressing mechanism, if a worker accidentally turns on the downward pressing mechanism, it may crush the arm, resulting in low safety. Since the processes of placing the battery case and outputting both require manual operation, the work efficiency is low. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems of low safety and low work efficiency in the production of storage batteries in the prior art, and to propose a shell pressing device for battery casting and welding.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A shell pressing device for battery casting and welding, including a fixed frame and a battery case. A positioning conveyor belt is arranged inside the fixed frame, a conveying table is arranged at the top of the fixed frame, an extrusion assembly is arranged inside the conveying table, an electric push cylinder is arranged on one side of the extrusion assembly, a downward pressing mechanism is arranged at the output end of the fixed frame, and a mold matching the battery case is arranged at the output end of the downward pressing mechanism.

[0007] Preferably, a support plate is fixedly installed corresponding to the positioning conveyor belt between the fixed frames.

[0008] Preferably, a plurality of positioning grooves matching the battery case are formed on the surface of the positioning conveyor belt.

[0009] Preferably, the conveying table is fixedly connected to the fixed frame through columns at the bottom. Blocking blocks are fixedly arranged on both sides of the conveying table, the distance between the blocking blocks matches the extrusion assembly, and reset rollers are arranged on the surface of the conveying table corresponding to the blocking blocks.

[0010] Preferably, an open groove matching the battery case is formed on the surface of the conveying table corresponding to the downward pressing mechanism.

[0011] Preferably, the extrusion assembly includes a fixed plate and a mounting seat. One side of the fixed plate is fixedly connected to the output end of the electric push cylinder. A partition plate and a sliding rod are fixedly connected between the fixed plate and the mounting seat. One end of the partition plate and the sliding rod is welded to the fixed plate, and the other end of the partition plate and the sliding rod is fixedly connected to the mounting seat. A plurality of pressing plates are slidably connected between the fixed plate and the mounting seat through the sliding rod. A return spring is fixedly connected between the pressing plates, and the return spring is located at the sliding rod.

[0012] Preferably, a rotating rod is arranged in the mounting seat. A plurality of pressing blocks are fixedly installed on the rotating rod facing the fixed plate. The two ends of the rotating rod are fixedly connected with movable rods. The pressing plate is provided with a groove matching the partition plate. Protection rollers are arranged at the ends of the pressing blocks and the movable rods.

[0013] Preferably, guiding blocks are arranged on the inner side of the bottom of the pressing mechanism corresponding to the movable rods. One side of the guiding blocks is fixedly connected to the pressing mechanism. Protection rollers are arranged at both ends of the guiding blocks. A limiting block is arranged at one end of the guiding block, and one side of the limiting block is fixedly connected to the pressing mechanism.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. Under the combined action of the fixed frame, the positioning conveyor belt, the conveying table, and the electric push cylinder of the present utility model, the mold can be automatically pushed to the working area of the pressing mechanism. After the shell pressing is completed, the semi-finished product can be output and a new battery shell can be replenished. When the worker loads the electrode plate group and the battery shell, they are both far away from the working area of the pressing mechanism, avoiding the risk caused by the worker accidentally turning on the pressing mechanism during loading.

[0016] 2. Under the combined action of the reset roller, the extrusion assembly, and the limiting block of the present utility model, the electrode plate can be pressed tightly during the process of the electric push cylinder pushing the extrusion assembly to the pressing mechanism, and the extrusion assembly can be driven to reset when the electric push cylinder resets, reducing the workload of the worker and improving the work efficiency at the same time. When the electric push cylinder extends to push the extrusion assembly, when it is pushed to the guiding block, the movable rod is guided to a horizontal state by the guiding block. During this process, the movable rod drives the pressing block to rotate, and the pressing block squeezes the pressing plate to make the pressing plate slide along the partition plate and the sliding rod, thereby completing the extrusion of the pole piece. When the extrusion assembly enters the working area of the pressing mechanism, the limiting block prevents the movable rod from resetting. When the extrusion assembly resets, the movable rod touches the reset roller and is lifted under the action of the reset roller. After lifting, it is elastically reset by the return spring.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to Figures 1-5 , a pressure shell device for battery casting and welding includes a fixed frame 1 and a battery case 23. A positioning conveyor belt 2 is arranged inside the fixed frame 1, a conveying table 3 is arranged at the top of the fixed frame 1, an extrusion assembly is arranged inside the conveying table 3, an electric push cylinder 4 is arranged on one side of the extrusion assembly, a downward pressing mechanism 5 is arranged at the output end of the fixed frame 1, and a mold 6 matching the battery case 23 is arranged at the output end of the downward pressing mechanism 5.

[0025] Further, support plates 7 are fixedly installed corresponding to the positioning conveyor belt 2 between the fixed frames 1 to bear the pressure during the operation of the downward pressing mechanism 5 through the support plates 7.

[0026] Further, a number of positioning grooves 8 matching the battery case 23 are formed on the surface of the positioning conveyor belt 2 to prevent the battery case 23 from shifting during transportation.

[0027] Further, the conveying table 3 is fixedly connected to the fixed frame 1 through the struts at the bottom. Stoppers 9 are fixedly arranged on both sides of the conveying table 3, and the distance between the stoppers 9 matches the extrusion assembly. Reset rollers 10 are arranged on the surface of the conveying table 3 corresponding to the stoppers 9.

[0028] The advantage of the above further improvement is that when the electric push cylinder 4 pulls back the extrusion assembly, the reset roller 10 can lift the movable rod 20 by touching, and after lifting, it is elastically reset by the reset spring 16.

[0029] Further, an open slot 11 matching the battery case 23 is provided on the surface of the conveying table 3 corresponding to the pressing mechanism 5, so that the pressing mechanism 5 can pass through the open slot 11.

[0030] Further, the extrusion assembly includes a fixed plate 12 and a mounting seat 17. One side of the fixed plate 12 is fixedly connected to the output end of the electric push cylinder 4. A partition plate 13 and a slide rod 14 are fixedly connected between the fixed plate 12 and the mounting seat 17. One ends of the partition plate 13 and the slide rod 14 are welded to the fixed plate 12, and the other ends of the partition plate 13 and the slide rod 14 are fixedly connected to the mounting seat 17. A plurality of pressing plates 15 are slidably connected between the fixed plate 12 and the mounting seat 17 through the slide rod 14. A reset spring 16 is fixedly connected between the pressing plates 15. The reset spring 16 is located at the slide rod 14. A rotating rod 18 is arranged in the mounting seat 17. A plurality of pressing blocks 19 are fixedly installed on the rotating rod 18 facing the fixed plate 12. Movable rods 20 are fixedly connected to both ends of the rotating rod 18. Grooves 1501 matching the partition plate 13 are provided on the pressing plates 15. Protection rollers are provided at the ends of the pressing blocks 19 and the movable rods 20.

[0031] It should be noted that: the grid formed by the fixed plate 12, the partition plate 13, and the pressing plates 15 for placing the electrode plates matches the grid inside the battery case 23 after extrusion.

[0032] The advantage of the above further improvement is that during the working process, the movable rod 20 drives the pressing block 19 to rotate by touching the guiding block 21. When the pressing block 19 rotates, it presses the pressing plate 15. After being pressed, the pressing plate 15 slides along the partition plate 13 and the slide rod 14 and presses the electrode sheet, thus achieving the function of automatically pressing the electrode sheet. By setting the protection rollers, the friction during the collision of the components can be reduced during operation, thereby improving the service life of the equipment and reducing the noise during the working process.

[0033] Further, a guiding block 21 is arranged on the inner side of the bottom of the pressing mechanism 5 corresponding to the movable rod 20. One side of the guiding block 21 is fixedly connected to the pressing mechanism 5. Protection rollers are provided at both ends of the guiding block 21. A limiting block 22 is provided at one end of the guiding block 21. One side of the limiting block 22 is fixedly connected to the pressing mechanism 5.

[0034] It should be noted that: the guiding block 21 is as Figure 4Inclined setting.

[0035] The further advantage of adopting the above is that by inclining the guiding block 21, the extrusion assembly is first blocked by the higher end of the guiding block 21 during the pushing process, causing the movable rod 20 to incline, and then the lower end of the guiding block 21 guides the movable rod 20 to the horizontal state, avoiding the rapid and large - amplitude rotation of the movable rod 20 hitting the conveying table 3, improving the service life of the equipment and reducing the noise during operation.

[0036] When the present utility model is in use, workers place the electrode plates in groups in the grid of the extrusion assembly, and place the battery cases 23 in groups of two in the positioning grooves 8. When using it for the first time, only the positioning conveyor belt 2 is started through the operation console, and the above steps are repeated until the first group of battery cases 23 enter the pressing area to complete the work preparation. After the preparation is completed, the device is controlled to operate through the operation console;

[0037] When the device operates, the electric push cylinder 4 extends, pushing the extrusion assembly to slide downward on the surface of the conveying table 3 towards the pressing mechanism 5. When the extrusion assembly is pushed to the guiding block 21, the movable rod 20 touches the higher end of the guiding block 21 and inclines. After being continuously pushed, the lower end of the guiding block 21 guides the movable rod 20 to the horizontal state. During this process, the movable rod 20 drives the pressing block 19 to rotate, and the pressing block 19 squeezes the pressing plate 15 when rotating. After being squeezed, the pressing plate 15 slides along the partition plate 13 and the sliding rod 14 and squeezes the pole piece, thus achieving the function of automatically squeezing the pole piece. Continuing to push the extrusion assembly, after the movable rod 20 leaves the guiding block 21, it enters the bottom of the limiting block 22, and the limiting block 22 prevents the movable rod 20 from resetting. When the extrusion assembly enters the working area of the pressing mechanism 5, the output end of the pressing mechanism 5 extends downward, and the pole plate group in the extrusion assembly is pressed into the battery case 23 through the mold 6. When the pressing of the case is completed and the pressing assembly resets, the electric push cylinder 4 retracts, pulling the extrusion assembly to reset. When the extrusion assembly passes through the reset roller 10, the protection roller at one end of the movable rod 20 collides with the reset roller 10 and drives the movable rod 20 to rotate. When the movable rod 20 rotates to an appropriate angle, it resets under the action of the rebound of the reset spring 16. When the extrusion assembly is completely reset, the positioning conveyor belt 2 rotates towards the output end, conveying the semi - finished storage battery after the case - pressing to the production line, and at the same time conveying the next group of battery cases 23 to the working area, completing a working process.

[0038] The above - mentioned is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
