Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary devices for power battery pack assembly, and in particular to an assembly device for power battery packs. Background Technology
[0002] A power battery pack, also known as a power battery module, is the core energy storage device for new energy vehicles and other equipment. It mainly consists of battery modules, battery management system, thermal management system, and electrical and mechanical components. When assembling a power battery pack, assembly equipment is needed to limit the positions of components such as the battery box to prevent them from shifting during assembly.
[0003] To this end, patent CN221314004U discloses a fixture for battery pack assembly, including a housing, support blocks, and partitions. The housing is equipped with a clamping device, which includes a motor and a threaded rod. The motor is fixedly connected to the inner surface of the housing via a bracket. One end of each of the two pull rods is movably connected to the surface of the clamping blocks via a rotating shaft. The surfaces of the clamping blocks on both sides slide and engage with the slide rails on the surface of the housing. Both clamping blocks penetrate the surface of the housing. This fixture for battery pack assembly, through the cooperation of an auxiliary positioning device and a clamping device, allows the clamping blocks on both sides to further clamp and fix the battery pack, after which the battery pack can be processed. The two sets of devices automatically clamp and fix the battery pack, eliminating the need for manual operation by the operator, thus improving the efficiency of the device and reducing the workload of the operator.
[0004] The existing technical solutions mentioned above have the following drawbacks: positioning the battery pack by using a motor and hydraulic cylinder is cumbersome and inconvenient for limiting the position of battery packs of different shapes, which causes some irregularly shaped battery packs to shift during positioning and assembly, thereby affecting the quality of power battery pack assembly and processing. Utility Model Content
[0005] The purpose of this invention is to provide an assembly device for a power battery pack, which solves the problem that existing power battery pack assembly devices are inconvenient for limiting the position of battery packs of different shapes.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an assembly equipment for a power battery pack, including an assembly table;
[0007] A limit mechanism is installed on the outer wall of the assembly table;
[0008] The limiting mechanism includes a frame plate fixedly installed at the bottom of the assembly table. A drive motor is fixedly connected to the bottom of the frame plate. A rotating rod is fixedly connected to the output shaft of the drive motor via a coupling. A movable plate is fixedly connected to the outer wall of the rotating rod. A first rotating shaft is installed on the outer wall of the movable plate. A receiving plate is installed on the outer wall of the first rotating shaft. A second rotating shaft is installed on the outer wall of the receiving plate. A base plate is installed on the outer wall of the second rotating shaft. A support block is fixedly connected to the top of the base plate.
[0009] The outer wall of the support block is fixedly connected to a positioning mechanism.
[0010] Preferably, the movable plate forms a rotating structure with the frame plate via a rotating rod, and the frame plate is U-shaped.
[0011] Preferably, the movable plate forms a rotating structure with the receiving plate via a first rotating shaft, and the receiving plate forms a rotating structure with the base plate via a second rotating shaft.
[0012] Preferably, the assembly platform has a sliding groove inside, and the bottom of the assembly platform is fixedly connected to a support leg. The assembly platform forms a sliding structure with the support block through the sliding groove.
[0013] Preferably, the positioning mechanism includes a limiting plate fixedly installed on the top of the support block, the limiting plate having a through hole inside, a positioning rod movably connected inside the limiting plate, a clamping plate fixedly connected to the outer wall of the positioning rod, and a return spring fixedly connected to one side of the clamping plate.
[0014] Preferably, the limiting plate forms a sliding structure with the positioning rod through through holes, and the through holes are evenly distributed along the outer wall of the limiting plate.
[0015] Preferably, the reset spring is sleeved on the outer wall of the positioning rod, and one end of the positioning rod is hemispherical.
[0016] The present invention provides an assembly device for a power battery pack, the advantages of which are:
[0017] With the assembly table, limiting mechanism and limiting plate set up, by placing the battery pack on the assembly table and starting the drive motor, the movable plate fixedly connected to the outer wall of the rotating rod can be rotated. Since the movable plate forms a rotating structure with the receiving plate through the first rotating shaft, it can drive the receiving plate to move, drive the bottom plate movably connected to the outer wall of the receiving plate to move, so that the limiting plate fixedly connected to the top of the support block can move, which can facilitate the clamping and limiting of battery packs of different sizes.
[0018] Furthermore, since the receiving plate is symmetrically arranged with the central axis of the movable plate, the two limiting plates can move synchronously, so that the battery pack is placed in the middle of the assembly table, which further improves the stability of the battery pack limiting.
[0019] By setting a limit plate, one end of the positioning rod is moved to contact the battery pack, causing the positioning rod to slide along the through hole, so that the assembly equipment can be used for battery packs of different shapes.
[0020] Furthermore, when the battery pack has an irregular shape, the positioning rods at different positions will slide to different depths along the through hole, which improves the stability and adaptability of the limit.
[0021] Furthermore, under the action of the return spring, the positioning rods at each position can always be in contact with the battery pack, which facilitates the limiting effect on battery packs of different shapes. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-5 The present invention provides a power battery pack assembly equipment, including an assembly table 1.
[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a limiting mechanism 2 is installed on the outer wall of the assembly table 1. The limiting mechanism 2 includes a frame plate 21 fixedly installed at the bottom of the assembly table 1. A drive motor 22 is fixedly connected to the bottom of the frame plate 21. The output shaft of the drive motor 22 is fixedly connected to a rotating rod 23 via a coupling. A movable plate 24 is fixedly connected to the outer wall of the rotating rod 23. A first rotating shaft 25 is installed on the outer wall of the movable plate 24. A receiving plate 26 is installed on the outer wall of the first rotating shaft 25. A second rotating shaft 27 is installed on the outer wall of the receiving plate 26. The outer wall is fitted with a base plate 28, and a support block 29 is fixedly connected to the top of the base plate 28. The movable plate 24 forms a rotating structure with the frame plate 21 through the rotating rod 23. The frame plate 21 is U-shaped. The movable plate 24 forms a rotating structure with the receiving plate 26 through the first rotating shaft 25. The receiving plate 26 forms a rotating structure with the base plate 28 through the second rotating shaft 27. The assembly table 1 has a sliding groove 4 inside. The bottom of the assembly table 1 is fixedly connected with a support leg 5. The assembly table 1 forms a sliding structure with the support block 29 through the sliding groove 4.
[0031] By placing the battery pack on the assembly table 1 and starting the drive motor 22, the movable plate 24 fixedly connected to the outer wall of the rotating rod 23 can rotate. Since the movable plate 24 forms a rotating structure with the receiving plate 26 through the first rotating shaft 25, it can drive the receiving plate 26 to move, drive the bottom plate 28 movably connected to the outer wall of the receiving plate 26 to move, and cause the limiting plate 31 fixedly connected to the top of the support block 29 to move, which facilitates the clamping and limiting of battery packs of different sizes.
[0032] Reference Figure 4 and Figure 5 As shown, a positioning mechanism 3 is fixedly connected to the outer wall of the support block 29. The positioning mechanism 3 includes a limiting plate 31 fixedly installed on the top of the support block 29. A through hole 32 is opened inside the limiting plate 31. A positioning rod 33 is movably connected inside the limiting plate 31. A retaining plate 34 is fixedly connected to the outer wall of the positioning rod 33. A return spring 35 is fixedly connected to one side of the retaining plate 34. The limiting plate 31 and the positioning rod 33 form a sliding structure through the through hole 32. The through holes 32 are evenly distributed along the outer wall of the limiting plate 31. The return spring 35 is sleeved on the outer wall of the positioning rod 33. One end of the positioning rod 33 is hemispherical.
[0033] The movement of the limiting plate 31 causes one end of the positioning rod 33 to contact the battery pack, making the positioning rod 33 slide along the through hole 32. This causes the clamping plate 34 to press against the return spring 35. When the shape of the battery pack is irregular, the positioning rods 33 at different positions will slide to different depths along the through hole 32. Under the action of the return spring 35, the positioning rods 33 at each position can always be in contact with the battery pack, which facilitates the limiting of battery packs of different shapes.
[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
