Description

TECHNICAL FIELD

[0001] The utility model relates to flatness detection device technical field, specifically a kind of galvanized substrate hot film imitated aluminium plate surface flatness detection device. BACKGROUND

[0002] Aluminum material is widely used in many fields due to its corrosion resistance, good machining performance and long service life. However, the price of aluminum material is relatively high, which limits its popularity in some cost-sensitive applications to some extent. In order to reduce the cost while maintaining the appearance and performance similar to aluminum material, an imitated aluminum plate is developed, whose base material is a galvanized substrate. The surface of the substrate is covered with a layer of VCM (Visual Cover Material) film with specific texture and performance through a hot covering process to achieve the effect of imitating aluminum. This imitated aluminum material not only has more economical cost, but also can well simulate the texture of aluminum material in appearance, so it gradually becomes a substitute for aluminum material.

[0003] However, during actual production, some imitated aluminum plate products may have flatness deviation problems after processing. This flatness deviation may be caused by improper temperature control during the hot covering process, unevenness of the substrate material, shrinkage rate difference of the VCM film and other factors. Since flatness is one of the important indicators for measuring the quality of plate material, imitated aluminum plates with flatness deviation cannot meet the use requirements, so strict flatness detection must be carried out after processing.

[0004] Currently, the commonly used flatness detection methods mainly include optical influence detection and ultrasonic detection. Although these two detection methods have high precision and reliability, they have relatively high requirements for the environment and cannot be disturbed by any interference such as vibration and temperature change, otherwise the accuracy of the detection results will be affected. In addition, the cost of these two detection methods is also relatively high, which increases the detection cost in the production process. UTILITY MODEL CONTENTS

[0005] To solve the technical problems in the background art, the utility model discloses a kind of galvanized substrate hot film imitated aluminium plate surface flatness detection device.

[0006] The utility model provides a kind of galvanized substrate hot film imitated aluminium plate surface flatness detection device, including the support plate of horizontal arrangement, the imitated aluminium plate of detection is set on support plate, and support plate is installed with:

[0007] Lifting column is set to multiple, linear arrangement, the straight line formed by its position is perpendicular to the moving direction of imitated aluminium plate, and lifting column is movably connected with support plate, so that its height can be adjusted;

[0008] The displacement sensor is installed below the lifting column, and its detection end is connected to the lower end of the lifting column.

[0009] During testing, the top of the lifting column should be flush with the upper surface of the support plate.

[0010] During testing, the imitation aluminum plate is placed on the upper surface of the support plate, and then the plate is moved to cover the lifting column. If the lifting column moves downwards a distance exceeding a set value, the flatness of the imitation aluminum plate is deemed unsatisfactory. Both sides of the imitation aluminum plate are also tested. The advantages of this setup are: 1. The combination of the lifting column and displacement sensor allows for precise measurement of the flatness of the imitation aluminum plate surface, ensuring product quality; 2. The position of the lifting column allows for testing of one side of the imitation aluminum plate with a single movement, resulting in high testing efficiency; 3. The device has a simple structure and is easy to operate and maintain.

[0011] The installation position of the lifting column directly affects the convenience of inspection of the aluminum-imitation plate. Based on this, a further improvement is made: a slot is opened in the center of the support plate; the lifting column is set in the slot; the width of the slot is configured such that when the aluminum-imitation plate moves from one side of the slot to the other side, the center of gravity of the aluminum-imitation plate is always located above the support plate, offset from the slot.

[0012] The specific installation structure of the lifting bollard is as follows: a connecting plate is installed on the lower end face of the support plate; a guide sleeve is installed on the connecting plate; and the lifting bollard is inserted into the guide sleeve.

[0013] Installing the displacement sensor separately would make the structure of this invention more complex and the cost higher. Therefore, a further improvement is made by installing the displacement sensor at the lower end of the guide sleeve.

[0014] The accuracy of the displacement sensor directly affects the detection accuracy of the aluminum plate. Based on this, the further improvement is that the displacement sensor is a laser displacement sensor.

[0015] Because the lifting column tends to move freely downwards under gravity, affecting the normal inspection of the aluminum-look plate, a further improvement is made: multiple evenly distributed rubber strips are engaged with the inner wall of the guide sleeve; these rubber strips connect to the lifting column. The rubber strips increase the frictional force of the lifting column's movement, thereby increasing the resistance to its descent and making the column's position more stable.

[0016] Because the aluminum-look plate is prone to sliding friction with the top of the lifting column when it moves, which causes the aluminum-look plate to be worn, a further improvement is made: the top of the lifting column is equipped with a movable roller; the axis of the roller is perpendicular to the direction of movement of the aluminum-look plate.

[0017] Because there is a gap between adjacent rollers, it is difficult to detect when parts of the imitation aluminum plate with unevenness pass between adjacent rollers. Based on this, a further improvement is made: the lifting column is set as two rows arranged in parallel; the rollers of one row are staggered from the rollers of the other row.

[0018] To ensure that there are no blind spots during the inspection of the aluminum-imitation plate, a further design is made: the spacing between the rollers in the same row is configured such that the gap between the projections of one row of rollers is covered by the projection of the other row of rollers in the radial projection of the rollers.

[0019] If the rollers are misaligned, they will directly cause wear to the aluminum-like plate. Therefore, the following improvements are made: the inner wall of the guide sleeve is provided with an axially arranged limiting groove; the outer wall of the lifting column is provided with a limiting strip that engages with the limiting groove.

[0020] The beneficial effects of this utility model are: 1. By combining the lifting column and the displacement sensor, the flatness of the surface of the aluminum-imitation plate can be accurately measured, thereby ensuring product quality; 2. The position setting of the lifting column allows the aluminum-imitation plate to be inspected on one side with just one movement, resulting in high inspection efficiency; 3. The device has a simple structure and is easy to operate and maintain. Attached Figure Description

Detailed implementation mode

[0030] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0031] As Figures 1-3 shown, the present utility model discloses a device for detecting the surface flatness of a galvanized substrate heat-coated imitation aluminum plate, including a bracket 11, on the top of which a horizontally arranged support plate 1 is provided, and the imitation aluminum plate to be detected is placed on the support plate 1 for detection.

[0032] A connecting plate 5 is installed on the lower end surface of the support plate 1. The connecting plate 5 is in a "U" shape with the opening upward and is fixedly locked on the support plate 1 by bolts.

[0033] A long circular notch 4 is provided at the center position of the support plate 1, and its length direction is perpendicular to the moving direction of the imitation aluminum plate. The width of the notch 4 is configured such that during the process of the imitation aluminum plate moving from one side of the notch 4 to the other side, the center of gravity of the imitation aluminum plate is always located directly above the support plate 1 and错开 from the notch 4, so that the imitation aluminum plate will not fall downward from the notch 4. A connecting plate 5 is installed on the lower end surface of the support plate 1, directly below the notch 4. Two rows of vertically arranged mounting holes 13 are provided on the connecting plate 5, and the straight line formed by their positions is perpendicular to the moving direction of the imitation aluminum plate. A lifting column 2 is arranged in the mounting hole 13, and its height is adjustable. The specific installation structure of the lifting column 2 is: as Figures 4-7 shown, a guide sleeve 6 is provided, which is composed of an integrally formed and coaxially arranged guiding part 61 and a connecting part 62. The diameter of the connecting part 62 is smaller than that of the guiding part 61, so that the connecting part 62 forms a shoulder. The connecting part 62 passes through the mounting hole 13 downward, and its shoulder is clamped at the upper end of the mounting hole 13. The connecting part 62 is provided with an external thread and is fixedly locked by a locking nut 12 connected by a thread, so as to realize the detachable connection of the guide sleeve 6. Two symmetric and vertically arranged ribs 14 are provided on the hole wall of the mounting hole 13, and vertically arranged clamping grooves 15 are provided on the outer wall of the connecting part 62, which are clamped with the ribs 14, so as to realize the installation limit of the guide sleeve 6.

[0034] The lifting column 2 is inserted into the guiding part 61 to realize the lifting guidance of the lifting column 2. Two symmetric and vertically arranged limit grooves 9 are provided on the inner wall of the guiding part 61, and limit strips 10 for clamping the limit grooves 9 are provided on the outer wall of the lifting column 2, so as to realize the position limit of the lifting column 2.

[0035] The inner wall of the guide part 61 is also provided with six rotationally symmetrical, arc-shaped mounting grooves, in which rubber strips 7 are installed. They are connected by an interference fit, so that the rubber strips 7 protrude from the inner wall of the guide part 61 and are connected to the lifting column 2 under compression. This creates pressure between the rubber strips 7 and the lifting column 2, increases the friction of the lifting column 2, increases the resistance to the descent of the lifting column 2, and makes its position more stable.

[0036] The upper end of the lifting column 2 is equipped with a roller 8 for rolling connection, which is used to roll and connect with the imitation aluminum plate to prevent the surface of the imitation aluminum plate from being scratched or worn. Under the combined action of the limiting groove 9 engaging the limiting strip 10 and the locking groove 15 engaging the locking strip, the position of the roller 8 can be maintained so that its axis is perpendicular to the moving direction of the imitation aluminum plate.

[0037] One row of rollers 8 is staggered with the other row of rollers 8, and the spacing between rollers 8 in the same row is configured such that the gap between the projections of one row of rollers 8 is covered by the projection of the other row of rollers 8. Furthermore, the length of the projection formed by the rollers 8 is greater than the width of the aluminum-imitation plate. This arrangement ensures that there are no blind spots during the inspection of the aluminum-imitation plate.

[0038] The connecting part 62 is also provided with an internal thread, and a displacement sensor 3 is threadedly connected to it. The detection end of the displacement sensor 3 is connected to the lower end of the lifting column 2. In this embodiment, the displacement sensor 3 is a laser displacement sensor, which has higher detection accuracy. Moreover, mounting the displacement sensor 3 on the connecting part 62 simplifies the structure of this utility model and reduces costs.

[0039] The working principle of this embodiment is as follows: First, pull the lifting column 2 upward so that the upper end of the roller 8 is higher than the upper end surface of the support plate 1. Then, use a template with a flat lower end surface that meets the usage requirements to cover the slot 4 and drive the lifting column 2 to descend. This ensures that the upper end of the roller 8 is flush with the upper end surface of the support plate 1. Finally, move the aluminum plate to be tested and pass through the slot 4. When the lifting column 2 moves downward a distance exceeding the set value, it is determined that the flatness of the aluminum plate does not meet the requirements. Moreover, both sides of the aluminum plate are tested.

[0040] The beneficial effects of this embodiment are: 1. By combining the lifting column 2 and the displacement sensor 3, the flatness of the surface of the aluminum-imitation plate can be accurately measured, thereby ensuring product quality; 2. The position setting of the lifting column 2 allows the aluminum-imitation plate to be inspected on one side by moving the plate once, resulting in high inspection efficiency; 3. The device has a simple structure and is easy to operate and maintain.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
