Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery packaging, in particular to a pressing jig for lithium battery packaging. Background Art

[0002] During lithium battery production, battery modules often need to be pressed together before being packaged. Pressing is usually done by moving extrusion plates driven by two motors, thereby squeezing multiple battery modules. After the extrusion is completed, the battery modules need to be manually secured with steel strips on the top and bottom. This method is prone to the following problems during actual operation:

[0003] First of all, when installing the steel belt, it is necessary to pre-install the steel belt on the outside of the steel belt embedded plate below, and the battery pack is placed above the embedded plate. After extrusion, the steel belt is manually moved and the extrusion equipment is released to complete the installation of the steel belt. This arrangement is very convenient for installing the upper steel belt, and it can be directly sleeved. When the lower steel belt is moved to the outside of the battery module, the staff stands on one side. When the steel belt is moved up, the battery module blocks the staff's line of sight. At the same time, the steel belt is very easy to deform, and it is impossible to manually drive the steel belt to move up smoothly. Therefore, there is a situation where the steel belt cannot be accurately sleeved on the outside of the battery module, which delays the assembly efficiency of the battery module. Therefore, a pressing jig for lithium battery packaging is proposed to address the above problems. Utility Model Content

[0004] The purpose of the present invention is to provide a pressing jig for lithium battery packaging to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pressing jig for lithium battery packaging, comprising a pressing frame, an extrusion device and a pressing plate,

[0006] Both sides of the upper portion of the pressing frame are fixedly connected to laterally arranged extrusion equipment, and the free ends of the extrusion equipment are fixedly connected to pressing plates;

[0007] A guide assembly for installing the steel belt is fixedly connected to the center of the pressing frame, and upward moving assemblies are provided on both sides of the guide assembly;

[0008] The upward moving component includes a fixed frame, a synchronous motor and a threaded shaft. The outer side of the fixed frame is fixedly connected to the pressing frame, the interior of the fixed frame is fixedly connected to the synchronous motor, the main shaft end of the synchronous motor is fixedly connected to the threaded shaft, and the other end of the threaded shaft is rotatably connected to the fixed frame, the outer side of the threaded shaft is spirally connected to the threaded sleeve, and the outer side of the threaded sleeve is fixedly connected to the upward moving frame.

[0009] Furthermore, the upward moving frame is composed of a transverse plate and a C-shaped frame, and one end of the transverse plate is fixedly connected to the bottom of the C-shaped frame, and the top of the C-shaped frame of the upward moving frame is flush with the upper surface of the workbench of the pressing frame.

[0010] During lithium battery production, battery modules often need to be pressed together before being packaged. Pressing is usually done by moving extrusion plates driven by two motors, thereby squeezing multiple battery modules. After the extrusion is completed, the battery modules need to be manually secured with steel strips on the top and bottom. This method is prone to the following problems during actual operation:

[0011] First, when installing the steel belt, it is necessary to pre-install the steel belt on the outside of the steel belt embedded plate below, and the battery pack is placed above the embedded plate. After extrusion, the steel belt is manually moved and the extrusion equipment is released to complete the installation of the steel belt. This setting makes it very convenient to install the upper steel belt and it can be directly sleeved. When the lower steel belt is moved to the outside of the battery module, the worker stands on one side and the battery module blocks the worker's sight when moving the steel belt upward. At the same time, the steel belt is very easy to deform and it is difficult to manually drive the steel belt upward smoothly. Therefore, there is a situation where the steel belt cannot be accurately sleeved on the outside of the battery module, which delays the assembly efficiency of the battery module. When in use, the power is turned on and the steel belt is placed on the outside of the guide assembly. After the battery module is extruded, the synchronous motor drives the threaded shaft to rotate, the threaded shaft drives the threaded sleeve to rotate, and the threaded sleeve drives the outer upper frame to move. The upper frame can smoothly push the steel belt above it, making it convenient to sleeve it on the outside of the battery module, and the fixation purpose can be achieved by releasing it through the pressing plate.

[0012] Furthermore, the guide assembly includes a mounting frame, an adjusting motor and a threaded rod, the outer side of the mounting frame is fixedly connected to the pressing frame, the interior of the mounting frame is fixedly connected to the adjusting motor, the end of the main shaft of the adjusting motor is fixedly connected to the threaded rod, the other end of the threaded rod is rotatably connected to the mounting frame, the outer side of the threaded rod is spirally connected to a threaded barrel, the outer side of the threaded barrel is fixedly connected to a movable plate, and the upper surface of the movable plate is fixedly connected to the guide plate;

[0013] The upper surface of the installation frame is fixedly connected with a steel strip embedded plate.

[0014] Furthermore, there are four guide plates, and the guide plates are arranged at an angle.

[0015] Furthermore, the top of the guide plate is configured to be pointed.

[0016] Furthermore, inclined grooves are provided at the four corners of the steel strip embedded plate.

[0017] When the lower steel belt is sleeved on the outside of the battery module, the adjustment motor is started in advance, and the threaded rod rotates at this time, driving the outer threaded cylinder and the movable plate to move up, thereby moving the guide plate up. When the lower steel belt moves up, its multiple guide plates serve the purpose of guidance, ensuring that the steel belt is stably sleeved on the outside of the battery module; the multiple grooves on the outside of the steel belt embedded plate can be used to accommodate the guide plates to prevent the guide plates from expanding outward and affecting the placement of the steel belt.

[0018] The beneficial effects of the utility model are:

[0019] When the utility model is in use, the steel belt is placed on the outside of the guide assembly. After the battery module is extruded, the synchronous motor drives the threaded shaft to rotate, the threaded shaft drives the threaded sleeve to rotate, and the threaded sleeve drives the outer upper frame to move. The upper frame can smoothly push the steel belt above it, making it convenient to sleeve it on the outside of the battery module. The fixing purpose can be achieved by releasing the pressing plate.

[0020] When the lower steel belt is sleeved on the outside of the battery module, the adjustment motor is started in advance. At this time, the threaded rod rotates, and the threaded rod drives the outer threaded cylinder and the movable plate to move up, thereby moving the guide plate up. When the lower steel belt moves up, its multiple guide plates serve as a guide to ensure that the steel belt is stably sleeved on the outside of the battery module.

[0021] The multiple grooves on the outside of the steel strip embedded plate can be used to accommodate the guide plate to prevent the guide plate from expanding outward and affecting the placement of the steel strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1 、 Figure 2 and Figure 3 , the utility model provides a technical solution:

[0030] A pressing jig for lithium battery packaging, comprising a pressing frame 1, an extrusion device 2 and a pressing plate 3,

[0031] Both sides of the upper portion of the pressing frame 1 are fixedly connected to a laterally arranged extrusion device 2, and a pressing plate 3 is fixedly connected to the free end of the extrusion device 2;

[0032] A guide assembly 5 for installing the steel belt is fixedly connected to the center of the pressing frame 1, and upward moving assemblies 4 are provided on both sides of the guide assembly 5;

[0033] The above-mentioned upward moving component 4 includes a fixed frame 401, a synchronous motor 402 and a threaded shaft 403. The outer side of the above-mentioned fixed frame 401 is fixedly connected to the pressing frame 1, and the interior of the above-mentioned fixed frame 401 is fixedly connected to the synchronous motor 402. The main shaft end of the above-mentioned synchronous motor 402 is fixedly connected to the threaded shaft 403, and the other end of the threaded shaft 403 is rotatably connected to the fixed frame 401. The outer side of the above-mentioned threaded shaft 403 is spirally connected to the threaded sleeve 404, and the outer side of the above-mentioned threaded sleeve 404 is fixedly connected to the upward moving frame 405.

[0034] The upward moving frame 405 is composed of a transverse plate and a C-shaped frame, and one end of the transverse plate is fixedly connected to the bottom of the C-shaped frame. The top of the C-shaped frame of the upward moving frame 405 is flush with the upper surface of the workbench of the pressing frame 1.

[0035] When producing lithium batteries, it is often necessary to press the battery modules and then package them. During the pressing process, two sets of motor equipment are generally used to drive the extrusion plate to move, thereby extruding multiple battery modules. After the extrusion is completed, it is necessary to manually put on the upper and lower parts of the battery modules with fixed steel belts. This method is prone to the following problems during actual operation: First, when installing the steel belt, it is necessary to pre-install the steel belt on the outside of the lower steel belt embedded plate, and the battery pack is placed above the embedded plate. After extrusion, the steel belt is manually moved and the extrusion equipment is released to complete the installation of the steel belt. This setting is very convenient for installing the upper steel belt, which can be directly connected, and the lower steel belt is moved to the outside of the battery module. When the worker stands on one side, when the steel belt is moved up, the battery module blocks the worker's sight. At the same time, the steel belt is very easy to deform and cannot be moved up smoothly by manual labor. Therefore, the steel belt cannot be accurately sleeved on the outside of the battery module, which delays the assembly efficiency of the battery module. When the power is turned on during use, the steel belt is placed on the outside of the guide assembly 5. After the battery module is extruded, the synchronous motor 402 drives the threaded shaft 403 to rotate, the threaded shaft 403 drives the threaded sleeve 404 to rotate, and the threaded sleeve 404 drives the outer upward frame 405 to move. The upward frame 405 can smoothly push the steel belt above it, so that it can be sleeved on the outside of the battery module, and the fixing purpose can be achieved by releasing it through the pressing plate 3.

[0036] In this embodiment, the upper moving frame 405 is composed of a transverse plate and a C-shaped frame. The C-shaped frame is buried inside the upper surface of the pressing frame 1. It is flush with the upper surface of the pressing frame 1, which is convenient for the placement of the steel belt. When the steel belt is installed under the battery module, it drives the C-shaped frame to move through the transverse plate. At this time, the steel belt can be driven to move smoothly in the form of a surface, making it convenient for it to be put on the outside of the pressed battery module.

[0037] Example 2: This example is an improvement on Example 1. Figure 4 and Figure 5 Specifically, the guide assembly 5 includes a mounting frame 501, an adjusting motor 502 and a threaded rod 503. The outer side of the mounting frame 501 is fixedly connected to the pressing frame 1, the interior of the mounting frame 501 is fixedly connected to the adjusting motor 502, the end of the main shaft of the adjusting motor 502 is fixedly connected to the threaded rod 503, the other end of the threaded rod 503 is rotatably connected to the mounting frame 501, the outer side of the threaded rod 503 is spirally connected to a threaded barrel 504, the outer side of the threaded barrel 504 is fixedly connected to a movable plate 505, and the upper surface of the movable plate 505 is fixedly connected to a guide plate 506;

[0038] The upper surface of the installation frame 501 is fixedly connected with a steel strip embedded plate 507 .

[0039] There are four guide plates 506 , and the guide plates 506 are arranged at an angle.

[0040] The top of the guide plate 506 is pointed.

[0041] The four corners of the steel strip embedded plate 507 are each provided with an inclined groove 508 .

[0042] When the lower steel belt is sleeved on the outside of the battery module, the adjustment motor 502 is pre-activated, and the threaded rod 503 rotates, driving the outer threaded cylinder 504 and the movable plate 505 to move upward, thereby moving the guide plate 506 upward. When the lower steel belt moves upward, the multiple guide plates 506 serve as guides to ensure that the steel belt is stably sleeved on the outside of the battery module; the multiple grooves 508 on the outside of the steel belt embedded plate 507 can be used to accommodate the guide plates 506, preventing the guide plates 506 from expanding outward and affecting the placement of the steel belt;

[0043] In this embodiment, the guide plate 506 is arranged at an angle, so that during the upward movement of the steel belt, it can be smoothly positioned on the outside of the battery module through the guidance of the guide plate 506, and the grooves 508 are arranged at the four corners of the steel belt embedded plate 507, which is convenient for guiding the four corners of the steel belt and ensuring that it is smoothly installed on the outside of the battery module.

[0044] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
