Description

Technical Field

[0001] This utility model belongs to the field of material box correction technology, specifically relating to a material box correction mechanism. Background Technology

[0002] In the battery production process, the precise transport and positioning of the battery aluminum shell box is crucial. With the rapid development of the battery industry, the requirements for production efficiency and product quality are constantly increasing. As a key piece of equipment to ensure the precise transport of aluminum shells, the performance of the box correction mechanism directly affects the overall efficiency of the production line.

[0003] Currently, there are various correction mechanisms available on the market for aluminum battery casings. Some correction mechanisms use mechanical blocks or limiting devices to simply restrict the position of the casing to achieve a certain degree of correction. However, these mechanisms can only handle minor deviations in the casing position. For cylindrical casings, it is difficult to accurately reset them to the center position. In actual production, cylindrical casings are prone to large deviations due to factors such as transmission vibration and inertia. Existing mechanical block correction mechanisms cannot effectively address this, resulting in reduced alignment accuracy between the aluminum casing and processing equipment in subsequent processes, affecting product quality. For example, welding position deviations may occur in the welding process, reducing the battery's sealing and safety.

[0004] Other correction mechanisms use photoelectric sensors in conjunction with simple motor drive devices to correct the alignment of the material box. However, when the opening of the material box is irregular, such as a square or strip-shaped opening, its functional limitations become apparent. These correction mechanisms lack the ability to rotate and adjust the position of the irregular material box opening, and cannot meet the specific requirements of different processes for the opening direction of the irregular material box. In the battery electrolyte filling process, if the opening direction of the irregular material box is incorrect, the electrolyte gun cannot be accurately aligned with the opening, resulting in inaccurate electrolyte volume, which affects the performance consistency and service life of the battery.

[0005] In summary, existing battery aluminum casing material box correction mechanisms are significantly inadequate in terms of precise repositioning of cylindrical material boxes and rotational adjustment of the opening direction of irregularly shaped material boxes, failing to meet the urgent needs of the current battery manufacturing industry for efficient, precise, and universal material box correction. Utility Model Content

[0006] The purpose of this invention is to provide a material box correction mechanism that can accurately reset the cylindrical material box to the middle position, ensuring the alignment accuracy of subsequent welding processes and improving battery sealing, and can also flexibly adjust the opening direction of the material box with irregular openings to ensure accurate operation of processes such as liquid injection.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A material box correction mechanism includes a transmission frame, with multiple transmission rollers rotatably connected inside the transmission frame, and each pair of adjacent transmission rollers being driven by a transmission belt. A first motor is mounted on the transmission frame, and the output end of the first motor passes through the transmission frame and is connected to one of the transmission rollers.

[0009] Multiple first electric push rods are fixed to the bottom of the inner side of the transmission frame. A baffle is installed vertically upward on the stroke rod of the first electric push rod.

Each cleaning roller is located between every two adjacent rotating rollers, and the edge of the cleaning roller extends outside the abutment plate. A drive mechanism is installed inside the abutment plate.

[0013] The drive mechanism includes gears fixed to the outside of each of the rotating rollers and each of the cleaning rollers, and every two adjacent gears are meshed with each other. A second motor is also installed inside the abutment plate, and the output end of the second motor is connected to one of the rotating rollers or the cleaning rollers.

Detailed Implementation

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-4 As shown, a material box correction mechanism includes a transmission frame 1. Multiple transmission rollers 2 are rotatably connected inside the transmission frame 1, and each pair of adjacent transmission rollers 2 is connected by a transmission belt 3. Each transmission roller 2 is equipped with a transmission wheel, and the multiple transmission belts 3 are mounted on the transmission wheels. A first motor 4 is mounted on the transmission frame 1, and the output end of the first motor 4 passes through the transmission frame 1 and connects to one of the transmission rollers 2. The surface of the transmission roller 2 is provided with an anti-slip rubber layer to increase friction with the bottom of the material box and prevent slippage during transmission. The transmission belt 3 adopts a synchronous belt structure, and the teeth on the transmission wheels mesh with the synchronous belt to ensure the synchronous rotation of the multiple transmission rollers 2.

[0027] When the material box is being driven, the material box is placed on top of the transmission roller 2, and the first motor 4 is driven so that the output end of the first motor 4 drives one of the transmission rollers 2 to rotate. Through the setting of the transmission belt 3, multiple transmission rollers 2 can be driven to rotate in the same direction, thereby driving the material box to be driven on the transmission roller 2.

[0028] Multiple first electric push rods 6 are fixed to the bottom of the inner side of the transmission frame 1. A baffle 7 is installed vertically upward on the stroke rod of the first electric push rod 6. The baffle 7 is located between two adjacent transmission rollers 2. Mounting brackets 8 are fixed on both sides of the transmission frame 1. Second electric push rods 9 are installed in the two mounting brackets 8. The stroke rods of the two second electric push rods 9 are in a position close to each other. Abutment plates 13 are installed at the ends of the stroke rods of the two second electric push rods 9.

[0029] At least one detection sensor 5 is provided on the top of the transmission frame 1. The detection sensor 5 can be a photoelectric sensor or a vision camera, etc. When the detection sensor 5 detects that the material box has deviated from its moving position, it can drive the first electric push rod 6, so that the stroke rod of the first electric push rod 6 moves upward and drives the baffle 7 to move upward to block the material box. By driving the second electric push rod 9, the stroke rod of the second electric push rod 9 drives the two abutment plates 13 to move closer to each other and clamp and abut the material box. Since the two second electric push rods 9 are driven at the same time, the abutment plates 13 can abut the material box to the center position, thereby correcting the deviation of the material box. The detection sensor 5 can also be a through-beam photoelectric sensor, which is installed in pairs on both sides of the top of the transmission frame 1. The detection beam is perpendicular to the material box transmission direction. When the material box deviates and the beam blocking position changes, the sensor transmits the signal to the control system. After the algorithm calculates the deviation, it triggers the first electric push rod 6 and the second electric push rod 9 to act.

[0030] A rolling mechanism is installed inside the abutment plate 13.

[0031] See attached document Figure 4 The rolling mechanism includes multiple rotating rollers 14 rotatably connected inside the abutment plate 13. The edges of the rotating rollers 14 extend outside the abutment plate 13. Multiple cleaning rollers 17 are also rotatably connected inside the abutment plate 13. The surface of the cleaning rollers 17 is covered with fiber brushes. The brushes have moderate hardness, which can effectively remove dust from the surface of the material box without damaging the coating on the surface of the material box. The number of cleaning rollers 17 is one less than the number of rotating rollers 14. Each cleaning roller 17 is located between every two adjacent rotating rollers 14. The edges of the cleaning rollers 17 extend outside the abutment plate 13. A drive mechanism is installed inside the abutment plate 13.

[0032] By setting the rotating roller 14, the drive mechanism can drive multiple rotating rollers 14 to rotate during operation. The rotating roller 14 contacts the cylindrical material box, causing the material box to rotate. If the opening of the material box is irregular, the irregular opening can be rotated and adjusted to correct its deviation. The outer side of the rotating roller 14 is provided with a soft pad to increase the friction between it and the material box. The cleaning roller 17 is set to clean the outer side of the material box, ensuring the effective completion of the next step.

[0033] See attached document Figure 4 The drive mechanism includes gears 15 fixed to the outside of each rotating roller 14 and each cleaning roller 17, and every two adjacent gears 15 are meshed with each other. A second motor 16 is also installed in the abutment plate 13. The output end of the second motor 16 is connected to one of the rotating rollers 14 or the cleaning roller 17. When it is necessary to adjust the opening direction of the irregular material box, the control system sends a command to the second motor 16 to drive the rotating roller 14 to rotate in the forward or reverse direction. The friction force drives the material box to rotate to the set angle. The angle accuracy is fed back to the control system in real time by the encoder. A sensor similar to the detection sensor 5 can also be set on the baffle 7 to monitor the angle of the material box opening in real time.

[0034] When the second motor 16 is driven, it can drive one of the rotating rollers 14 and the cleaning roller 17 to rotate. The gears 15 on the multiple rotating rollers 14 are spaced apart, so that the multiple rotating rollers 14 and the multiple cleaning rollers 17 rotate in the same direction, while the rotating rollers 14 and the cleaning rollers 17 rotate in opposite directions. This allows the multiple rotating rollers 14 to rotate synchronously and drive the material box to rotate, thus correcting the deviation of the material box. When the cleaning roller 17 rotates, it can clean the outside of the material box.

[0035] See attached document Figure 3The second electric push rod 9 has an assembly block 10 mounted on its travel rod. The assembly block 10 contains a slot 11, and a plug 12 is magnetically attached to the slot 11. The plug 12 is fixedly connected to the abutment plate 13. When the abutment plate 13 needs to be replaced, the plug 12 can be removed from the assembly block 10, allowing for replacement or repair of the abutment plate 13. Alternatively, a different model of abutment plate 13 can be used, thus adapting to different models of material boxes. The assembly block 10 contains a magnet, and the plug 12 also has a magnet. Iron, two magnets attract each other, so that the assembly block 10 and the insert block 12 can be attracted to each other. Furthermore, a blocking bracket 18 is provided on the side of the assembly block 10 near the abutment plate 13. The assembly block 10 and the blocking bracket 18 form a slot 11. The insert block 12 is inserted into and magnetically attracted in the slot 11. Through this arrangement, the insert block 12 is inserted into the slot 11. The blocking bracket 18 can prevent the insert block 12 from falling off or shifting laterally. Combined with the magnetic attraction effect, the stability of the abutment plate 13 is guaranteed.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
