Description

Technical Field

[0001] This invention relates to the field of aluminum foil processing technology, and more specifically, to an online aluminum foil thickness detection and calibration device. Background Technology

[0002] Aluminum foil is widely used in high-end fields, and thickness accuracy is a core quality indicator. During the rolling process, factors such as roll wear and rolling force fluctuations can cause local thickness deviations in aluminum foil. This is especially true for high-precision products, where even a micron-level deviation can lead to scrapping.

[0003] In existing technologies, offline sampling inspection suffers from lag and is prone to producing batches of defective products; conventional online detection and calibration are disconnected, requiring manual intervention and adjustment, which is inefficient and prone to large errors. Therefore, developing an online device that links detection and calibration is key to solving the problem of aluminum foil thickness control. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an online aluminum foil thickness detection and calibration device, which features real-time linkage and high processing accuracy.

[0005] To solve the above-mentioned technical problems, the present invention achieves its objective as follows: The present invention relates to an online aluminum foil thickness detection and calibration device, comprising a front conveyor roller group and a rear conveyor roller group, wherein an online detection and calibration mechanism is provided between the front conveyor roller group and the rear conveyor roller group; the online detection and calibration mechanism includes side frames arranged symmetrically on the left and right, and an online detection unit near the front conveyor roller group and an online calibration unit near the rear conveyor roller group are provided between the side frames.

[0006] The present invention is further configured such that: the online detection unit includes a first limiting hole opened on the side frame and extending vertically, a first limiting block that moves vertically is slidably connected in the first limiting hole, an upper detection roller is rotatably connected between the first limiting blocks, a lower detection roller is rotatably connected to the side frame below the upper detection roller, a first transmission column that extends vertically and is slidably connected to the side frame above the first limiting block, the lower end of the first transmission column is connected to the first limiting block, and a first elastic member that abuts against the side frame at its upper end and abuts against the first limiting block at its lower end is sleeved on the first transmission column; The online calibration unit includes a second limiting hole that extends vertically and is opened on the side frame. A second limiting block that moves vertically is slidably connected in the second limiting hole. An upper calibration roller is rotatably connected between the second limiting blocks. A lower calibration roller that is rotatably connected to the side frame is provided below the upper calibration roller. A second transmission column that extends vertically and is slidably connected to the side frame is provided above the second limiting block. The lower end of the second transmission column is connected to the second limiting block. A second elastic member that abuts against the second limiting block at its upper end and against the side frame at its lower end is provided in the second limiting hole. The side frame is rotatably connected to a linkage rocker that extends forward and backward and swings up and down. One end of the linkage rocker has a first arm extending forward and the other end has a second arm extending backward. The upper end of the first transmission column abuts against the first arm and the upper end of the second transmission column abuts against the second arm.

[0007] The present invention is further configured such that: the upper end of the first transmission column is provided with a first active ball head, the front end of the first arm is provided with a first driven ball head, and the spherical surface of the first active ball head is in close contact with the spherical surface of the first driven ball head.

[0008] The present invention is further configured such that: the upper end of the second transmission column is provided with a second driven ball head, the rear end of the second arm is provided with a second driving ball head, and the spherical surface of the second driven ball head is in close contact with the spherical surface of the second driving ball head.

[0009] The present invention is further configured such that both the first elastic element and the second elastic element are compression springs.

[0010] The present invention is further configured such that: the side frame is provided with a first positioning protrusion extending into the upper end of the first elastic member, and the first limiting block is provided with a second positioning protrusion extending into the lower end of the first elastic member; The second limiting block is provided with a third positioning protrusion extending into the upper end of the second elastic member, and the side frame is provided with a fourth positioning protrusion extending into the lower end of the second elastic member.

[0011] The present invention is further configured such that the upper detection roller is a plastic roller with a surface coated with adhesive.

[0012] In summary, the present invention has the following beneficial effects: 1. A mechanical link is established through a linkage rocker arm. When the aluminum foil is too thick, the upper detection roller moves upward, and the upper calibration roller moves downward synchronously via a transmission for secondary rolling. The purely mechanical structure has a fast response, no signal delay, and can adaptively compensate for thickness allowance, significantly reducing the defect rate.

[0013] 2. It can be directly integrated into existing production lines, offering strong adaptability; the ball joint and elastic component positioning design reduce wear and failure risks, extending service life. Its core reliance on mechanical structure reduces the use of electronic components, lowering procurement and maintenance costs. Attached Figure Description

[0015] To enable those skilled in the art to better understand the technical solutions of the present invention, preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are merely for further illustrating the features and advantages of the present invention, and not for limiting the scope of the patent claims of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0016] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] Example 1 See Figure 1 and Figure 2 As shown, the aluminum foil thickness online detection and calibration device involved in this embodiment includes a front conveyor roller group 100 and a rear conveyor roller group 200. An online detection and calibration mechanism 300 is provided between the front conveyor roller group 100 and the rear conveyor roller group 200. The online detection and calibration mechanism 300 includes side frames 301 arranged symmetrically on the left and right. An online detection unit is provided near the front conveyor roller group and an online calibration unit is provided near the rear conveyor roller group between the side frames 301.

[0018] Furthermore, the online detection unit includes a first limiting hole 302 opened on the side frame 301 and extending vertically. A first limiting block 303 that moves vertically is slidably connected in the first limiting hole 302. An upper detection roller 304 is rotatably connected between the first limiting blocks 303. A lower detection roller 305 is rotatably connected to the side frame below the upper detection roller 304. A first transmission column 306 that extends vertically and is slidably connected to the side frame is provided above the first limiting block 303. The lower end of the first transmission column 306 is connected to the first limiting block 303. A first elastic member 307 that abuts against the side frame at its upper end and against the first limiting block at its lower end is sleeved on the first transmission column 306. The online calibration unit includes a second limiting hole 308 extending vertically and opening on the side frame 301. A second limiting block 309 that moves vertically is slidably connected in the second limiting hole 308. An upper calibration roller 310 is rotatably connected between the second limiting blocks 309. A lower calibration roller 311 is rotatably connected to the side frame below the upper calibration roller 310. A second transmission column 312 extending vertically and slidably connected to the side frame is provided above the second limiting block 309. The lower end of the second transmission column 312 is connected to the second limiting block 309. A second elastic member 313 with its upper end abutting against the second limiting block and its lower end abutting against the side frame is provided in the second limiting hole 308. The side frame 301 is rotatably connected to a linkage rocker 314 that extends forward and backward and swings up and down. One end of the linkage rocker 314 has a first arm 3141 extending forward and the other end has a second arm 3142 extending backward. The upper end of the first transmission column 306 abuts against the first arm 3141, and the upper end of the second transmission column 312 abuts against the second arm 3142.

[0019] Furthermore, the upper end of the first transmission column 306 is provided with a first active ball head 3061, and the front end of the first arm 3141 is provided with a first driven ball head 3143, with the spherical surface of the first active ball head 3061 closely attached to the spherical surface of the first driven ball head 3143.

[0020] Furthermore, the upper end of the second transmission column 312 is provided with a second driven ball head 3121, and the rear end of the second arm 3142 is provided with a second active ball head 3144, with the spherical surface of the second driven ball head 3121 closely attached to the spherical surface of the second active ball head 3144.

[0021] Furthermore, both the first elastic element 307 and the second elastic element 313 are compression springs.

[0022] This device is installed between the front and rear conveyor roller groups of the aluminum foil rolling production line, with symmetrically fixed side frames to form the main framework. In the online inspection unit, the upper inspection roller is slidably connected to the first limiting hole of the side frame via a first limiting block, and a first elastic element is sleeved outside the first transmission column, always providing downward preload to the upper inspection roller; the online calibration unit uses a second elastic element installed in the opposite direction to provide upward support to the upper calibration roller. A linkage rocker is rotatably connected to the side frame, with its first arm engaging with the ball head of the first transmission column, and its second arm abutting against the ball head of the second transmission column, forming a closed-loop transmission.

[0023] During operation, the aluminum foil is fed in by the front conveyor roller group, passing between the upper and lower detection rollers. If the thickness is too large, it will lift the upper detection roller and drive the first drive column upward, pushing the first arm of the linkage rocker arm to swing upward, causing the second arm to press down on the second drive column, forcing the upper calibration roller to overcome the elastic force of the second elastic element and move downward. Subsequently, the aluminum foil enters between the upper and lower calibration rollers and is rolled a second time to eliminate the thickness excess. Finally, it is sent out by the rear conveyor roller group, completing the synchronous operation of detection and calibration.

[0024] Example 2 See Figure 1 and Figure 2 As shown, the aluminum foil thickness online detection and calibration device involved in this embodiment is further configured based on embodiment 1, wherein the side frame 301 is provided with a first positioning protrusion (unmarked) extending into the upper end of the first elastic member, and the first limiting block 303 is provided with a second positioning protrusion (unmarked) extending into the lower end of the first elastic member. The second limiting block 309 is provided with a third positioning protrusion (unmarked) extending into the upper end of the second elastic member, and the side frame 301 is provided with a fourth positioning protrusion (unmarked) extending into the lower end of the second elastic member.

[0025] In this embodiment, the first positioning protrusion and the second positioning protrusion are used for the installation and positioning of the first elastic element.

[0026] The third and fourth positioning protrusions are used for positioning the second elastic element during installation.

[0027] Example 3 See Figure 1 and Figure 2 As shown, the aluminum foil thickness online detection and calibration device involved in this embodiment is further configured, based on embodiment 1, wherein the upper detection roller 304 is a plastic roller with a surface coated with adhesive.

[0028] In this embodiment, by setting the upper detection roller as a plastic roller with a coated surface, the transmission friction can be ensured while reducing its weight and lowering detection and processing errors.

[0029] The aluminum foil thickness online detection and calibration device involved in this invention establishes a mechanical connection through a linkage rocker arm. When the aluminum foil is too thick, the upper detection roller moves upward, and the upper calibration roller moves downward synchronously via transmission for secondary rolling. The purely mechanical structure offers fast response and no signal delay, and can adaptively compensate for thickness allowances, significantly reducing the defect rate. Furthermore, it can be directly embedded into existing production lines, exhibiting strong adaptability. The ball joint fit and elastic component positioning design reduce wear and failure risks, extending service life. The core relies on a mechanical structure, reducing the use of electronic components, lowering procurement and maintenance costs, and offering comprehensive overall functionality and strong practicality.
