Description

Technical Field

[0001] The invention belongs to the technical field of aluminum foil strip cutting, and in particular relates to a device and method for detecting aluminum powder in aluminum plate strip cutting edges. Background Art

[0002] Aluminum strips need to be trimmed after cold rolling. The width and edge quality of 0.2-10mm thick strips must be improved before sales. The shearing of aluminum alloy strips is mainly done by disc knife shearing. The disc knife does not have a sharp blade, and the upper and lower knives do not touch each other. It is generally used to cut aluminum alloy strips with a thickness of 0.01mm to 14mm and a tensile strength of 30N / mm2 to 500N / mm2. When used in the production line for shearing aluminum alloy strips, the shearing tool is required to have high design accuracy. High-precision tolerance is a necessary condition to ensure the quality of strip shearing, so that the width of the finished strip can be accurate.

[0003] Although the plate and strip trimming machines have made different degrees of development and progress in recent years, the shearing knives have been greatly improved and optimized, and the shearing process has been continuously improved and innovated, the problem of edge burrs has never been completely solved; and in the process of trimming, aluminum powders of different particle sizes will be generated along with the trimming process. Driven by certain external factors (wind and airflow), these aluminum powders and burrs are very easy to be contaminated to the edges and other positions of the strip, which brings quality risks to the subsequent processing of the plate and strip, especially single zero foil, double zero foil, battery foil plate and strip blanks. Due to the lack of a cleaning process, burrs and aluminum powders of various particle sizes will form metal indentation defects in the subsequent processing, causing broken strips and holes (such as Fig.13 , 14 ), resulting in a large amount of waste.

[0004] However, these holes do not contain other impurity elements under scanning electron microscope and energy spectrum analysis, but the aluminum content is high. It can be basically determined that the metal is pressed into the plate by aluminum powder and aluminum chips, which occupies the volume of the matrix during subsequent processing, causing tearing and breaking of the strip or forming holes. Because the aluminum powder and burrs of the plate and strip cutting edge are in a state of unorganized emission and dispersion with the airflow and air after they are generated, it is very difficult to control and manage them. Therefore, it is particularly important to detect and observe the aluminum powder of the plate and strip cutting edge. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] like Figure 1 As shown, a device for detecting aluminum powder in trimming of aluminum plate and strip includes a detection box 5 and a trimming assembly. The detection box 5 is installed on both sides of the trimming strip, and the trimming assembly is arranged inside the detection box 5. The inner wall of the detection box 5 is provided with an adhesive sheet (not shown in the figure) for absorbing aluminum powder and burrs. By installing a special detection device around the trimming assembly of the trimming of the aluminum plate and strip, the aluminum powder and burrs are captured and taken under a microscope for observation, measurement and counting, so that the number and size of particles in a unit volume can be calculated.

The detection box 5 is composed of a detachable multi-panel splicing, and the six inner wall surfaces inside the detection box 5 are respectively glued with adhesive sheets with a black base to absorb burrs and aluminum powder in the space. After the equipment has been running for 1 hour or a fixed time, open the detection box 5, take out 6 adhesive sheets, and observe the number and size of the particles under a microscope. After multiple tests, track and record the effects of particles of different particle sizes and quantities on the processing of broken belts and hole sizes of the next process products. Based on which size and quantity of particles will not cause broken belts and the hole size meets customer requirements.

[0042] like Figure 2-11 As shown, as another preferred embodiment of the present invention, the detection box 5 includes two boxes 51, which are spliced ​​to form the detection box 5; the bottom end of the box 51 is connected to the transverse movement mechanism, and the two boxes 51 are driven to move closer or farther from each other by the transverse movement mechanism. This method facilitates the disassembly of the detection box 5 and quickly realizes the installation or removal of the adhesive sheet.

[0043] Furthermore, the trimming assembly includes a cutter shaft 2 and a disc cutter 3 disposed on both sides of the cutter shaft 2. A cutter groove roller shaft 4 is disposed below the cutter shaft 2. A plurality of cutter grooves 41 are disposed on both sides of the cutter groove roller shaft 4, wherein one of the cutter grooves 41 is disposed correspondingly to the disc cutter 3.

[0044] Furthermore, a through slot 52 for the strip to pass through is provided on one side of the box body 51, and a semicircular slot 1 53 and slot 2 54 are provided on one side of the box body 51, respectively. The cutter shaft 2 is provided in slot 1 53, and the cutter groove roller shaft 4 is provided in slot 2 54, and the end of the through slot 52 is connected to slot 2 54. The aluminum foil strip is provided on the cutter groove roller shaft 4, and the aluminum foil strip crosses the detection box 5 through the through slot 52. Part of the aluminum foil (i.e., the edges of the aluminum foil on both sides) is provided in the detection box 5, and the edge cutting operation is performed by the disc cutter 3 in the detection box 5. The aluminum powder and burrs generated during the edge cutting are scattered in the detection box 5 and adhere to the adhesive sheet on the inner wall of the detection box 5. The adhesive sheet is removed later and the number and size of the particles are observed under a microscope. This structure can ensure that the detection box 5 surrounds the disc cutter 3, and realizes the effective collection of the edge cutting aluminum powder and burrs.

[0045] Furthermore, the transverse mechanism includes a sliding base 62, a transverse motor 7 and a bidirectional screw 72. The trimming assembly is arranged on the frame 1. A driving motor 21 connected to the cutter shaft 2 is arranged on one side of the frame 1. A mounting groove 12 is arranged in the middle of the frame 1. Two bearing seats 71 are arranged in the mounting groove 12. A bidirectional screw 72 is connected between the two bearing seats 71. The bidirectional screw 72 has screw segments with different rotation directions at both ends. Slide grooves 11 are arranged on both sides of the frame 1. Slide blocks 6 are arranged on both sides of the sliding base 62. Slide rails 61 are arranged at the bottom end of the slide block 6. The slide rails 61 are slidably arranged in the slide grooves 11 to achieve the sliding limit of the slide block 6. There are two sliding bases 62. A screw nut 64 is arranged at the middle bottom end of each sliding base 62. The screw nut 64 is arranged in the mounting groove 12. The two screw nuts 64 are respectively matched and connected to the corresponding bidirectional screw 72; the bottom end of the box 51 and the upper end of the slide block 6 are detachably connected.

[0046] Reference Figure 3 , 4 As shown, this structure can synchronously drive the two sliding bases 62 to move away from each other through the screw motor, thereby achieving the boxes 51 on both sides of the cutter shaft 2 to move away from each other, so as to facilitate the disassembly and assembly of the adhesive sheet.

[0047] Reference Figure 5 , 6 As shown, this structure can synchronously drive the two sliding bases 62 to approach each other through a screw motor, thereby achieving the box bodies 51 on both sides of the cutter shaft 2 to approach each other and wrap the disc cutter 3, thereby collecting aluminum powder and burrs during trimming.

[0048] Furthermore, a retaining edge 63 is disposed at the upper end of the slider 6 , and the retaining edge 63 is disposed closely against the outer wall of the box body 51 , thereby enhancing the connection reliability between the box body 51 and the slider 6 .

[0049] like Figure 8As shown, further, T-shaped connectors are respectively provided on both sides of the box body 51, and the connectors include a vertical plate 8 and a horizontal plate 81 integrally connected to the vertical plate 8, the horizontal plate 81 is provided on the upper side of the through slot 52, and the horizontal plate 81 and the vertical plate 8 are connected to the box body 51 by screws 82. Since the through slot 52 is provided on one side of the box body 51, and the aluminum foil is inserted into the through slot 52, and generally the aluminum foil and the inner wall surface of the through slot 52 do not contact, and the thickness of the box body 51 is limited, in the process of cutting, in order to avoid the deformation of the through slot 52 due to the vibration of the box body 51 and other reasons, affecting the normal insertion of the aluminum foil, a connector is provided to reinforce and tighten the box body 51 on the upper side of the through slot 52 to ensure the dimensional accuracy of the slot and avoid the deformation of the slot and friction of the aluminum foil.

[0050] like Fig. 9 As shown, further, one side of the vertical plate 8 is integrally connected with a second horizontal plate 85, and there is a gap between the second horizontal plate 85 and the first horizontal plate 81. The second horizontal plate 85 is arranged at the lower side of the through slot 52, and the first horizontal plate 81 and the second horizontal plate 85 are arranged around the outer side of the through slot 52 to strengthen the strength of the slot position of the entire box body 51; the vertical plate 8 and the first horizontal plate 81 are connected by the first tie rod 83 and the second tie rod 84, and the vertical plate 8 and the second horizontal plate 85 are connected by the third tie rod 86. This structure can strengthen the support of the box body 51 on the upper and lower sides of the through slot 52 as a whole, and prevent the vibration deformation of the box body 51 from causing the position change of the through slot 52.

[0051] Furthermore, a guide roller assembly is rotatably provided at the bottom end of the transverse plate 1 81 , and a guide roller assembly is rotatably provided at the upper end of the transverse plate 2 85 , so that the aluminum foil can be guided when passing through the through slot 52 .

[0052] Example 2

[0053] like Fig.12 As shown, in the present invention, outer rails 9 extending to the outside of the frame 1 are respectively provided on both sides of the frame 1, and the outer rails 9 are arranged in an arc shape. In this way, a pulley can be provided at the bottom end of the slider 6, and the pulley is arranged on the outer rails 9 and the slide groove 11 to achieve the sliding limit of the slider 6 and the detection box 5. This design uses manual driving of the box body 51 to move, or other methods such as electric driving can be used, so that the two boxes 51 can be close to each other to surround the disc cutter 3 (such as Fig.12 The two boxes 51 are moved away from each other and moved to the two sides of the rack 1, avoiding the strip area, that is, avoiding the aluminum foil (such as Fig.12(shown on the right). In this way, the aluminum powder and burrs during the trimming can be collected and tested online. During the trimming of the aluminum foil, when the adhesive sheet in the detection box 5 collects aluminum powder within a certain period of time, the detection box 5 is moved to the outside of the aluminum foil, and the adhesive sheet in the detection box 5 can be safely and conveniently removed and placed under a microscope to observe the number and size of particles. In this way, when the adhesive sheet is removed, aluminum powder and burrs will not fall on the moving aluminum foil, avoiding errors in the subsequent press-in defect detection. At the same time, when the adhesive sheet is removed, the detection box is already far away from the aluminum foil, which can avoid safety hazards.
