Description

Technical Field

[0001] The utility model relates to the field of cutting machines, in particular to an automatic loading and cutting machine for lithium batteries. Background Art

[0002] After the battery pack is sealed, the aluminum-plastic film on the sides of the battery pack needs to be trimmed. Traditionally, the cutting process uses an upper and lower cutter blade to cut the film. When cutting the film on the sides of large battery packs, longer upper and lower cutters are required. As the cutters lengthen, they are prone to deformation during the cutting process, resulting in uneven cuts and even burrs on the sides of the battery pack, which affects the quality of the battery pack. Furthermore, traditional battery pack cutting mechanisms lack automatic loading mechanisms to transport the battery packs. Instead, the battery packs must be manually placed on a positioning jig before trimming. This manual loading and unloading process not only makes it easy for workers to come into contact with the cutters, potentially causing injuries, but also reduces loading and unloading efficiency and increases production costs. Furthermore, this process places heavy workload on workers and increases labor costs for the company, making it difficult to meet the requirements of large-scale, mass-produced, and automated production.

[0015] The positioning groove on the pressing sheet is used in conjunction with the scoring knife mounting seat to install the scoring knife on the scoring knife mounting seat. By adjusting the position and depth of the scoring knife in the positioning groove, the oblique angle of the scoring knife and the depth of the scoring knife in cutting the aluminum-plastic film can be adjusted. In fact, it is now suitable for cutting aluminum-plastic films of different depths or thicknesses without replacing the scoring knife, thereby achieving its strong versatility and making the operation of the scoring knife more flexible, more convenient and faster to use.

The coordinated use of the lower cutting groove and the upper cutting groove not only ensures that the cutting knife can smoothly and quickly perform accurate cutting, thereby avoiding the phenomenon of deviation during the cutting process, but also ensures a good cutting effect of the aluminum-plastic film and improves the cutting efficiency.

[0020] Preferably, the loading and unloading conveying mechanism includes two feed linear sliding assemblies arranged in parallel above the worktable, the two feed linear sliding assemblies are installed on the worktable through a module bracket, and a positioning fixture is commonly connected to the two feed linear sliding assemblies.

The servo motor is driven and connected to the screw bearing assembly through a belt transmission assembly, and the screw bearing assembly is connected and installed with the positioning fixture. Specifically, the servo motor is driven and connected to the ball screw of the screw bearing assembly through a belt transmission assembly, and the nut support seat of the screw bearing assembly is connected and installed with the positioning fixture through a connector or a drag chain.

[0021] A servo motor is used to drive the screw bearing assembly to rotate forward and reverse to drive the positioning fixture to move back and forth on the two feeding linear sliding assemblies, so that the battery packs to be processed and the battery packs that have been processed can be automatically loaded and unloaded or automatically fed through the positioning fixture, which solves the problems of traditional manual loading and unloading of battery packs, which makes it easy for hands to touch the cutter and cause work injuries, low efficiency of battery pack loading and unloading, high labor intensity for workers and high production costs of battery packs.

This maximum distance is the processing position for cutting the aluminum-plastic film on the side of the battery pack.

[0026] Compared with the existing technology, the beneficial effects of the present invention are:

[0027] 1. The structure of the cutting mechanism and the supporting mechanism are designed separately. When the cutting mechanism and the supporting mechanism are closed, not only the aluminum-plastic film on the side of the battery pack is pressed against the supporting mechanism and the battery pack is clamped and fixed, but also the aluminum-plastic film on the side of the battery pack can be accurately cut with only one cutting knife. The cut edge of the battery pack is smooth and burr-free. The cutting mechanism has the advantages of high cutting precision, good cutting effect and high cutting efficiency, which can greatly improve the quality of battery pack molding, thereby avoiding the traditional method of cutting the aluminum-plastic film by closing the upper cutting knife and the lower cutting knife, and the phenomenon that the cutting knife is easily deformed during the process of cutting the aluminum-plastic film, resulting in uneven cut edge of the aluminum-plastic film on the side of the battery pack and even burrs.

[0028] 2. The structure of the cutting blade mounting seat of the cutting mechanism is designed so that the cutting blade mounting seat can be used in conjunction with the pressing sheet to adjust the oblique angle of the cutting blade and the depth of the cutting blade in cutting the aluminum-plastic film, thereby achieving the purpose of strong versatility, more convenient operation, greater operational flexibility and more complete functions. It solves the problem that the current cutter generally cannot directly adjust the oblique cutting angle and the cutting depth.

[0029] 3. It automatically loads and unloads the battery packs by arranging a loading and unloading conveying mechanism on the workbench, thereby avoiding the phenomenon that manual conveying of battery packs and manual positioning of battery packs are prone to contact with the cutter and cause work-related injuries. It effectively solves the problem that the traditional battery pack cutting mechanism is not equipped with an automatic loading mechanism and uses manual loading and unloading of battery packs, which causes manual hands to easily contact with the cutter and cause work-related injuries, low efficiency of battery pack loading and unloading and high production costs.

[0048] In one embodiment, the loading and unloading conveying mechanism 2 includes two feeding linear sliding assemblies 21 arranged in parallel above the work table 1.

The two feeding linear sliding assemblies 21 are commonly connected to a positioning fixture 23. A motor bracket 24 is provided on the outer side of one of the feeding linear sliding assemblies 21, and a servo motor 25 is provided below one end of the motor bracket 24.

The battery supporting cylinder 38 of the supporting mechanism 3 drives the supporting base 33 to rise. At the same time, the battery pack pressing cylinder 75 of the cutting mechanism 4 drives the positioning rod 74 and the cutting knife 83 to descend synchronously by driving the connecting plate 72, the pressing guide rod bearing assembly 71 and the positioning cross plate 73, so that the positioning rod 74 of the cutting mechanism 4 and the supporting base 33 of the supporting mechanism 3 are close to each other to press the aluminum-plastic film on the side of the battery pack onto the supporting base 33 and clamp the battery pack, which avoids the movement of the battery pack and affects the cutting accuracy and cutting effect of the aluminum-plastic film.

[0051] When the rodless cylinder 76 of the cutting mechanism 4 drives the cutting knife 83 to move, the aluminum-plastic film on the side of the battery pack can be cut, and the cut aluminum-plastic film waste is recycled through the waste recycling box 35 of the supporting mechanism 3; when the cutting knife 83 completes the cutting of the aluminum-plastic film on the side of the battery pack, the supporting mechanism 3 descends, the cutting mechanism 4 rises, the supporting mechanism 3 and the cutting mechanism 4 are separated and reset, and the servo motor 25 drives the positioning fixture 23 to exit the relative spatial position of the supporting mechanism 3 and the cutting mechanism 4 through the belt transmission assembly 2 and the screw bearing assembly 26 and reset and retreat to unload the battery pack with the aluminum-plastic film cut.

[0052] The automatic feeding of the battery pack is realized by the loading and unloading conveying mechanism 2, so as to avoid the contact between the human hand and the cutter and the easy occurrence of work-related accidents; the cutting mechanism 4 and the supporting mechanism 3 are closed together to clamp the battery pack, so that it can automatically cut the aluminum-plastic film on the side of the battery pack with only one cutting knife 83, which ensures that the battery pack is smooth and avoids burrs on the cut, and realizes the automatic recovery of the cut waste. It has the advantages of high cutting accuracy, good cutting effect and high cutting efficiency for the battery pack, and it does not require manual participation in loading and unloading to achieve energy saving. The invention reduces the labor intensity of workers and the labor cost of enterprises, thereby reducing the production and processing costs. Its overall structural design not only solves the problem that the traditional aluminum-plastic film cutting process uses extended upper and lower cutters to cut the aluminum-plastic film on the side of the battery pack, but the extended cutters are easily deformed, resulting in uneven cuts or even burrs on the sides of the battery pack. It also solves the problem that the traditional battery pack cutting mechanism is not equipped with an automatic loading mechanism and uses manual loading and unloading of the battery pack, which makes it easy for the hands to touch the cutter and cause work injuries, low efficiency of battery pack loading and unloading, and high production costs.
