Description

Technical Field

[0001] The utility model relates to the technical field of off-line shape meters, in particular to an off-line shape meter for battery aluminum foil. Background Art

[0002] Offline shape meters for aluminum foil are specifically designed to measure the flatness of thin sheet materials such as aluminum foil. This type of instrument is crucial for quality control of aluminum foil production, as the shape of the foil directly affects its performance and appearance in the end-use application.

[0003] Existing offline shape meters typically include an unwinding and rewinding mechanism, as well as a guide mechanism. The guide mechanism comprises multiple parallel guide rollers, alternating vertically to ensure the stability of the aluminum foil during measurement. However, the width of the aluminum foil is shorter than the length of the guide rollers. This can lead to deviations between the two sides of the foil during the unwinding and rewinding process due to tension or the long length of the foil being fed through the multiple guide rollers. This can affect the rewinding of the rewinding rollers and the measurement data from the offline shape meter. Utility Model Content

[0004] In order to solve the technical problems existing in the above background technology, the utility model provides an offline flatness meter for battery aluminum foil.

[0005] The technical solution of this utility model is as follows:

[0006] An offline shape meter for battery aluminum foil comprises a base and a guide mechanism mounted thereon. The guide mechanism comprises a plurality of guide rollers arranged in a staggered manner and in parallel, wherein the axes of the guide rollers are aligned with the width direction of the base, and the upper guide rollers are on the same horizontal plane. The device also comprises two sets of aluminum foil straightening mechanisms located on the upper conductor rollers and arranged on both sides of the guide rollers in the width direction of the aluminum foil.

[0007] The aluminum foil straightening mechanism includes a support rod and a plurality of guide members arranged along its length. The two ends of the support rod are connected to the side of the base through a connecting rod. The position of the support rod along the axis of the guide roller is adjustable.

[0008] The plurality of guide members are respectively arranged corresponding to the plurality of guide rollers located above, and the lower end surface of the guide member is placed on the guide roller located above and is in sliding connection with the guide roller, and the position of the guide member along the axis direction of the guide roller is adjustable.

[0009] The aluminum foil passes through the unwinding mechanism of the offline flatness meter and the guide mechanism to the rewinding mechanism. The aluminum foil is passed through multiple guide rollers arranged upper and lower on the guide mechanism. Guide members are respectively provided on both sides of the aluminum foil. The vertical plane on one side of the guide member guides the two sides of the aluminum foil during transmission. The guide plate can help the aluminum foil maintain the correct travel path, reduce lateral movement, and thus reduce the possibility of deviation; and the position of the guide member and the support rod along the axial direction of the guide roller can be adjusted, which can be suitable for guiding aluminum foils of various specifications.

[0010] In order to avoid the distance between the two relative guides being too small, which will cause continuous wear on both sides of the aluminum foil, the vertical distance between the relative surfaces of the guides of the two aluminum foil straightening mechanisms is 1-5 mm larger than the width of the aluminum foil.

[0011] The connection structure between the upper part of the guide member and the support rod is that a mounting groove is provided on the side of the support rod close to the aluminum foil, and the mounting groove is a dovetail groove. The upper part of the guide member is adapted to the mounting groove, and the guide member is slidably connected to the mounting groove. The sliding direction is the axial direction of the guide roller, and the guide member is connected to the support rod through a first locking member.

[0012] The structure of the sliding connection between the above-mentioned guide member and the guide roller is that the lower end surface of the guide member is an arc-shaped surface adapted to the guide roller, and the curvature of the arc-shaped surface is not greater than 180°. This not only facilitates the installation of the guide member on the corresponding guide roller, but also improves the stability of the guide member in being set on the guide roller, and is used to guide one side of the aluminum foil.

[0013] Regarding the specific structure of the first locking member, the first locking member includes a first fastening bolt, the axis of the first fastening bolt is parallel to the axis of the guide roller, and one end of the first fastening bolt passes through the support rod and the mounting groove in sequence to be rotatably connected to the guide member. The first fastening bolt can be tightened or loosened, thereby driving the guide member to move only along the axis direction of the guide roller to adjust the distance from the side of the aluminum foil.

[0014] The internal structure of the above-mentioned guide member is that a long hole and a rotating groove are connected to each other, a baffle adapted to it is provided in the rotating groove, and one end of the first fastening bolt extends through the long hole into the rotating groove and is detachably connected to the baffle.

[0015] In order to facilitate the installation and removal of the baffle in the guide member, an upper opening communicating with the rotation groove is provided on the upper end surface of the guide member, and the size of the upper opening is larger than the size of the baffle.

[0016] Regarding the specific connection structure between the support rod and the connecting piece, non-circular adjustment holes are opened at both ends of the support rod along the length direction. The length direction of the non-circular adjustment hole is parallel to the axis of the guide roller. The connecting rod is passed through the non-circular adjustment hole and is detachably connected to the support rod through a second locking piece.

[0017] The beneficial effects of the present invention are:

[0018] Aluminum foil straightening mechanisms are provided on both sides of the aluminum foil on the guide roller. The guide members of the aluminum foil straightening mechanism are installed on the support rod and are provided in plurality, which are respectively arranged corresponding to the multiple guide rollers located above. The lower surface of a single guide roller is provided on the guide roller and is in sliding contact with the guide roller, thereby forming a multi-position guide for the aluminum foil on the guide roller, improving the guiding effect when the aluminum foil is rolled up, reducing the deviation of the aluminum foil, and reducing the impact on the detection data of the offline flatness meter;

[0019] The aluminum foil straightening mechanism is close to the multiple guide rollers located above, which makes it easy to adjust the support rods and multiple guide members in the axial direction of the guide rollers. The adjustment space is large and can be applied to guide aluminum foils of different specifications. The adjustment method is simple.

[0020] The material of the side of the guide member close to the aluminum foil can be a smooth material with a low friction coefficient such as polytetrafluoroethylene, polyethylene, polypropylene, etc. to avoid scratching or contamination of the side of the aluminum foil;

[0021] The lower end surface of the guide member is an arc-shaped surface adapted to the guide roller. The arc of the arc-shaped surface is no more than 180 degrees, which not only facilitates the installation of the guide member on the corresponding guide roller, but also improves the stability of the guide member on the guide roller, and is used to guide one side of the aluminum foil. The upper end of the guide member is higher than the upper end surface of the aluminum foil, and the lower end is lower than the lower surface of the aluminum foil located on the upper guide roller, which can increase the guiding area of the guide member.

[0022] When the guide member is driven to move only along the axial direction of the guide roller by the first fastening bolt, one end of the first fastening bolt located in the guide member is connected to a baffle, and the baffle can rotate in the rotating groove following the first fastening bolt. In order to facilitate the installation and disassembly of the baffle in the guide member, an upper opening connected to the rotating groove is provided on the upper end surface of the guide member, and the size of the upper opening is larger than the size of the baffle.
