Description

Technical Field

[0001] The present application relates to the technical field of flatness detection, and in particular to a surface flatness detection mechanism for an aluminum-based foil and a detection process thereof. Background Art

[0002] Aluminum foil is widely used in modern industry, especially in packaging, electronics and other industries. With the continuous increase in market demand and the continuous advancement of technology, the quality and performance requirements of aluminum foil are also increasing. Among them, the surface flatness of aluminum foil is one of the important indicators to measure its quality, which directly affects the use effect of the product and the satisfaction of the end user. Therefore, ensuring the stability and consistency of the surface flatness of aluminum foil is of great significance to improving product competitiveness.

[0003] In order to accurately detect the surface flatness of aluminum-based foil, existing technical means usually use contact detection methods or non-contact detection methods. Contact methods mainly include mechanical rollers, contact sensors, etc., which detect the unevenness of the aluminum-based foil surface through physical contact. Non-contact detection methods include optical sensors, laser scanners, etc., which do not require direct contact with the surface and achieve detection through light reflection or reflection time difference. However, these two methods have their own limitations and shortcomings in practical applications.

[0004] On the one hand, although the contact detection method has a simple structure, during long-term use, mechanical rollers and other components are prone to wear, resulting in a decrease in detection accuracy; at the same time, the contact method is prone to scratches or damage to the surface of aluminum-based foil, thereby affecting product quality; although the non-contact detection method can avoid direct damage to the material surface, when processing foils with large thickness differences, it is easily disturbed by external factors such as ambient light and dust, resulting in unstable detection results.

[0005] On the other hand, the existing inspection is for the aluminum-based foil in a static state after production. However, during the high-speed production process of the aluminum-based foil, if defect feedback cannot be obtained in time, batches of defective products will be produced, resulting in a waste of production costs.

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1-6 This application is described in further detail.

[0047] On the one hand, an embodiment of the present application discloses a mechanism for detecting the surface flatness of an aluminum-based foil.

[0048] Reference Figure 1 , Figure 2 and Figure 3 , an aluminum-based foil surface flatness detection mechanism comprises a bracket 1, a detection device 2 for detecting the thickness of the aluminum-based foil, and an accompanying device 3 installed on the bracket 1 and used to drive the detection device 2 to move synchronously with the aluminum-based foil;

[0049] The detection device 2 includes two detection components 21 and two driving components 22. The detection component 21 includes a slide rail 211 and a slider 212. The slider 212 slides on the slide rail 211 along the advancing direction of the aluminum-based foil. A connecting block 213 is provided on the slider 212. A linear laser emitting unit 214 and a linear laser receiving unit 215 are provided on the connecting block 213. The connecting block 213 is rotatably connected to the slider 212, and the rotation axis of the connecting block 213 and the slider 212 is parallel to the laser surface emitted by the linear laser emitting unit 214. A first driving member 216 for driving the connecting block 213 to rotate is provided on one slider 212. In the present application, the first driving member 216 is a motor. The main body of the first driving member 216 is fixed to the slider 212, and the output shaft is fixedly connected to the connecting block 213.

[0050] A driving assembly 22 is installed on one slide rail 211, and the driving assembly 22 is used to drive the slider 212 to slide on the slide rail 211, and there is a speed difference between the sliders 212 on different slide rails 211;

[0051] The two detection components 21 are respectively located on both sides of the width direction of the aluminum-based foil, and the laser plane emitted by the linear laser emitting unit 214 in one detection component 21 can always be received by the linear laser receiving unit 215 in the other detection component 21, thereby forming two mutually parallel laser planes, and the laser planes are perpendicular to the aluminum-based foil;

[0052] There are multiple detection devices 2, which are installed on the accompanying device 3 in sequence without gaps along the advancing direction of the aluminum-based foil;

[0053] After the personnel install the detection mechanism on the production line, the accompanying device 3 drives the multiple detection devices 2 to move forward at the same speed as the aluminum-based foil, and the slide rail 211 remains parallel to the aluminum-based foil;

[0054] During the forward movement of the detection device 2, the movement of the sliders 212 on the two detection components 21 can be selected as synchronous movement or asynchronous movement, provided that the first driving members 216 on the two detection components 21 respectively drive the connecting blocks 213 to rotate, so that the laser planes emitted by the linear laser emitting units 214 on the two connecting blocks 213 can be received by the linear laser receiving unit 215;

[0055] The preferred motion mode used in the present application is: the slider 212 on one of the detection components 21 remains stationary, and the slider 212 on the other detection component 21 is driven to slide by the driving component 22. When the slider 212 that slides first moves to the end of the slide rail 211, the driving component 22 stops moving, and the driving component 22 on the other detection component 21 starts to drive the slider 212 thereon to slide until it moves to the end, thereby forming two right-angled triangle scanning areas, and the two right-angled triangle areas constitute a rectangular scanning area;

[0056] On the other hand, since a laser surface is used, when there is a certain angle difference between the surface of the aluminum-based foil and the slide rail 211, the measurement result will not be affected as long as the thickness surface of the aluminum-based foil is always within the laser surface.

[0057] The accompanying device 3 drives the multiple detection devices 2 forward, so that the detection devices 2 remain relatively still with the aluminum-based foil. During the scanning process, the thickness side wall of the aluminum-based foil is in a state of vertical irradiation by the laser plane. The thickness of the aluminum-based foil is analyzed by the laser plane difference received by the linear laser receiving units 215 on both sides. The obtained comparison data is sent to the processor through a wireless device, and the processor controls the alarm or marking instrument to remind the personnel.

[0058] Compared with the synchronous motion detection of the slider 212, the asynchronous motion method can detect linear defects on the aluminum-based foil that are parallel to the width direction of the aluminum-based foil;

[0059] This is used to detect the flatness of aluminum-based foil during the production process.

[0060] Reference Figure 1 In order to perform uninterrupted detection, the accompanying device 3 may be provided with multiple ones. After the detection device 2 on one part of the accompanying device 3 has detected a certain section of the aluminum-based foil, the detection device 2 on another part of the accompanying device 3 will take over for precise detection. The detection device 2 on the accompanying device 3 that has been detected first will be restored to its initial state through the accompanying device 3, so as to perform uninterrupted flatness detection on the aluminum-based foil.

[0061] Reference Figure 2 and Figure 3 In the present application, the driving assembly 22 includes a screw 221 and a second driving member 222. The screw 221 is arranged parallel to the sliding direction of the slider 212, and the screw 221 is coaxially rotatably connected to the slide rail 211. The slider 212 is threadedly connected to the screw 221. In the present application, the second driving member 222 is a motor. The second driving member 222 body is fixed to the slide rail 211, and the output shaft of the second driving member 222 is coaxially fixedly connected to the screw 221.

[0062] The second driving member 222 drives the screw rod 221 to rotate, and the screw rod 221 drives the slider 212 to slide on the slide rail 211 .

[0063] Reference Figure 2 and Figure 3 , in order to realize that the second driving members 222 on the two driving components 22 in a detection device 2 rotate at different speeds, directions and start-up times, an aluminum-based foil surface flatness detection mechanism also includes a control device 4 for controlling the start-up of the driving component 22, the control device 4 includes a start-up component 41, the start-up component 41 includes a conductive strip 411 and a brush 412, each terminal on the second driving member 222 is connected to a brush 412, the number of conductive strips 411 is consistent with the number of terminals, the conductive strips 411 are arranged along the movement direction of the aluminum-based foil, and the brush 412 can contact the conductive strip 411;

[0064] By changing the current, motor and length of the conductive strip 411, the second driving member 222 is controlled to rotate at different speeds, directions and start-up times, and the rotation speed, direction and time of the screw 221 are changed, thereby controlling the movement of the slider 212 to change different scanning modes.

[0065] Reference Figure 1 and Figure 3In order to reduce the number of accompanying devices 3 and reduce costs, the accompanying device 3 in the present application includes an accompanying component 31, and the accompanying component 31 includes a conveyor belt 311, one of the belt surfaces of the conveyor belt 311 moves along the moving direction of the aluminum-based foil, and the belt surface of the conveyor belt 311 is parallel to the surface of the aluminum-based foil, and multiple detection devices 2 are installed in sequence without gaps along the circumference of the conveyor belt 311;

[0066] There are two starting components 41, one is used to start the second driving member 222 on the side of the conveyor belt 311 close to the aluminum-based foil to drive the detection component 21 to detect the aluminum-based foil, and the other starting component 41 is used to start the second driving member 222 on the side of the conveyor belt 311 away from the aluminum-based foil to drive the detection component 21 to reset;

[0067] By installing the detection device 2 on the side of the transmission belt, the conveyor belt 311 drives the detection device 2 to move in the same direction and speed as the aluminum-based foil, forming a circular motion, and continuously detecting the surface of the aluminum-based foil;

[0068] The starting component 41 located on the side of the conveyor belt 311 close to the aluminum-based foil is used to control the movement of the first driving component 216 in the detection component 21 located on the side of the conveyor belt 311 close to the aluminum-based foil, thereby changing the detection method. The starting component 41 located on the side of the conveyor belt away from the aluminum-based foil is used to restore the first driving component 216 after detection to the state before detection.

[0069] Reference Figure 1 and Figure 5 In the production site, the vibration of the machine will cause the aluminum-based foil to shake to a certain extent. In order to improve the accuracy of the detection, the detection mechanism also includes a stabilizing device 5 for stabilizing the aluminum-based foil. The stabilizing device 5 includes a shock absorbing component 51. The shock absorbing component 51 includes;

[0070] Mounting bracket 511 mounted on bracket 1:

[0071] There are two stabilizing rollers 512 for clamping the aluminum-based foil, and the stabilizing rollers 512 are arranged in parallel. The aluminum-based foil is clamped in the gap formed by the two stabilizing rollers 512. The two ends of the stabilizing rollers 512 are coaxially connected to a first mounting seat 513. The first mounting seat 513 is elastically slidably connected to the mounting frame 511, and there is friction between the first mounting seat 513 and the mounting frame 511. In normal state, the two stabilizing rollers 512 tend to move closer to each other.

[0072] There are two damping assemblies 51, which are distributed along the moving direction of the aluminum-based foil, and the detection device 2 is located between the two damping assemblies;

[0073] When the aluminum-based foil shakes, the stabilizing roller 512 is driven to move, and the stabilizing roller 512 drives the first mounting seat 513 to slide frictionally on the mounting frame 511 to offset the shaking of the aluminum-based foil. At the same time, the elastic sliding of the first mounting seat 513 and the mounting frame 511 ensures that the two stabilizing rollers 512 always clamp the aluminum-based foil between the two stabilizing rollers 512. By setting two shock-absorbing components 51, the stability of the aluminum-based foil in the detection section can be better guaranteed.

[0074] Reference Figure 5 In order to adjust the clamping force between the two stabilizing rollers 512, a second mounting seat 514 is provided on the mounting frame 511, and a sliding groove 5141 is provided on the second mounting seat 514. One end of a first mounting seat 513 is located in a sliding groove 5141 and elastically slides perpendicular to the surface of the aluminum-based foil, and there is friction between the first mounting seat 513 and the side wall of the sliding groove 5141. A side wall of the sliding groove 5141 and one end of a first mounting seat 513 form a pressure-equalizing chamber, and the four pressure-equalizing chambers are connected through a connecting pipe 515, and an air inlet is provided on the connecting pipe 515;

[0075] The air is filled into the equalizing chamber through the air inlet to increase or decrease the air pressure in the equalizing chamber, thereby changing the clamping force between the two stabilizing rollers 512 .

[0076] Reference Figure 6 In order to further improve the stability of the aluminum-based foil in the detection section, the stabilizing device 5 also includes a tensioning assembly 52, which includes a tensioning roller 521 and a first fixing member 523. The two ends of the tensioning roller 521 are coaxially connected to a third mounting seat 522, and the third mounting seat 522 slides on the bracket 1 along the vertical surface of the aluminum-based foil. The tensioning roller 521 is arranged parallel to the stabilizing roller 512, and the first fixing member 523 is used to fix the third mounting seat 522 on the bracket 1;

[0077] There are two tensioning assemblies 52, which are located between the two shock absorbing assemblies 51, and the detection device 2 is located between the two tensioning assemblies 52;

[0078] By adjusting the positions of the third mounting seats 522 of the two tensioning assemblies 52, the tensioning roller 521 is brought into contact with the surface of the aluminum-based foil to put it in a tensioned state, and the movement angle of the aluminum-based foil is adjusted according to the distance adjusted by the third mounting seats 522.

[0079] Reference Figure 6 In the present application, the first fixing member 523 is a screw 221, the first fixing member 523 is arranged along the sliding direction of the third mounting seat 522, and the first fixing member 523 is coaxially rotatably connected to the bracket 1, and the first fixing member 523 is threadedly connected to the third mounting seat 522;

[0080] The first fixing member 523 is threadedly connected to the bracket 1 to adjust the sliding distance of the third mounting seat 522 .

[0081] In the present application, if there is an undetectable gap between two adjacent detection devices 2, multiple accompanying devices 3 can be provided so that the detection devices 2 on different accompanying devices 3 are staggered for detection, so as to complete the complete detection of the aluminum-based foil.
