Abstract
Description
Technical Field
[0001] This utility model relates to the field of strip thickness detection technology, and in particular to a high-precision alloy thin strip thickness detection device. Background Technology
[0002] Alloy strip refers to a thin strip material with a certain thickness, width, and length, made from two or more metals or metals and non-metals through processes such as melting, forging, and rolling. Alloy strips typically possess specific chemical compositions and properties to meet diverse industrial and application needs. Their thickness is relatively thin, generally less than a few millimeters. Common alloy strips include stainless steel strips, titanium alloy strips, and copper alloy strips. These materials are widely used in electronics, aerospace, automotive manufacturing, machining, and architectural decoration. For example, in the electronics industry, they are used to manufacture leads and connectors for electronic components; in the aerospace field, they are used to manufacture aircraft structural components and engine parts.
[0003] When inspecting the thickness of alloy strips, small pits appear on the upper surface of the alloy strips, which cannot be accurately detected by the thickness inspection device. In addition, dirt or solids adhering to the upper and lower surfaces of the alloy strips further reduce the accuracy of the thickness inspection.
[0004] To address the problems in the existing technology, a high-precision alloy thin strip thickness detection device is provided. Utility Model Content
[0005] In view of this, the present invention proposes a high-precision alloy thin strip thickness detection device to solve the problems in the prior art.
[0006] The technical solution of this utility model is achieved as follows: This utility model provides a high-precision alloy thin strip thickness detection device, including a base, on one side of the upper part of the base, a laser thickness detector is provided; a placement slot is opened in the middle of the lower part of the base, and a tensioning component is provided at the bottom of the placement slot.
[0007] Furthermore, the tensioning assembly includes a first motor located at the bottom of the placement slot, and a screw connected to the output end of the first motor. The upper end of the screw engages with a moving block, which is slidably fitted inside the opening in the upper wall of the placement slot. A top block is fixedly connected to one side of the moving block. The upper surface of the top block has a rounded corner, and an alloy strip is pressed against the upper surface of the rounded corner. A sliding plate is fixedly connected to the middle of the lower surface of the top block. The lower part of the sliding plate is slidably fitted inside a sliding opening in one side of the limiting plate. One side of the limiting plate is fixedly connected to one side of the base.
[0008] Furthermore, a first abutment and a second abutment are fixed to one side of the upper part of the base, and the lower surfaces of the first abutment and the second abutment are pressed against both sides of the upper surface of the alloy strip.
[0009] Furthermore, a cleaning component is provided on one side of the base. The cleaning component is divided into two groups, and its outer surface respectively abuts against the upper and lower surfaces of the alloy strip.
[0010] Furthermore, the cleaning component is made of PVC foam material.
[0011] The present invention has the following advantages over the prior art:
[0012] (1) The high-precision alloy thin strip thickness detection device disclosed in this utility model, under the gradual upward pressing of the top block, makes both sides of the alloy thin strip pressed by the rounded corners press against the lower surfaces of the first and second push rods, and the alloy thin strip pressed by the rounded corners is supported upward, thereby keeping the alloy thin strip in a taut state during the detection work, avoiding the impact of loosening on the thickness detection work, and improving the detection effect;
[0013] (2) The alloy strip after being cleaned by the cleaning component will be gradually conveyed to the rounded corner. At the rounded corner, the alloy strip is bent along the angle of the rounded corner by the cooperation of the first and second abutments. The bending angle can clearly show a small pit, which can make the laser thickness detector detect the thickness of the alloy strip more accurately. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0022] like Figures 1-4 As shown in the figure, this utility model embodiment discloses a high-precision alloy thin strip thickness detection device, including a base 1, a laser thickness detector 2 is provided on one side of the upper part of the base 1; a placement slot 11 is opened in the middle of the lower part of the base 1, and a tensioning component 3 is provided at the bottom of the placement slot 11; a cleaning component 4 is provided on one side of the base 1.
[0023] In this embodiment, the tensioning component 3 includes a first motor 31 located at the bottom of the placement slot 11, and a screw 32 is connected to the output end of the first motor 31. The upper end of the screw 32 is engaged with a moving block 33. The moving block 33 is slidably fitted inside the sliding opening 12 opened on the upper wall of the placement slot 11. A top block 34 is fixedly connected to one side of the moving block 33. The upper end surface of the top block 34 is provided with a rounded corner 341. The upper surface of the rounded corner 341 abuts against an alloy strip 5. A sliding plate 35 is fixedly connected to the middle of the lower end surface of the top block 34. The lower part of the sliding plate 35 is slidably fitted inside the through opening 361 opened inside one side of the limiting plate 36. One side of the limiting plate 36 is fixedly connected to one side of the base 1. The first motor 31 is started to drive the screw 32 to rotate clockwise. The screw 32 spirally engages with the engagement hole on the moving block 33, causing the moving block 33 to move upward to the top block 34 and the sliding plate 35. The moving block 33 slides upward inside the sliding port 12, and the sliding plate 35 slides upward under force inside the through-hole 361 on the limiting plate 36. This effectively makes the top block 35 move upward stably. As the top block 35 moves upward, the rounded corner 341 abuts against the lower end face of the alloy strip 5. Under the gradual upward pressure of the top block 35, both sides of the alloy strip 5 pressed by the rounded corner 341 abut against the lower surfaces of the first abutment 37 and the second abutment 38. The part of the alloy strip 5 pressed by the rounded corner 341 is supported upward. This keeps the alloy strip 5 taut during the inspection process, which helps to ensure the tautness of the alloy strip 5 and avoids affecting the thickness inspection due to looseness, thus improving the inspection effect.
[0024] In this embodiment, a first abutment 37 and a second abutment 38 are fixed to one side of the upper part of the base 1. The lower surfaces of the first abutment 37 and the second abutment 38 press against both sides of the upper surface of the alloy strip 5. After cleaning, the alloy strip 5 is gradually conveyed to the rounded corner 341. At the rounded corner 341, the first abutment 37 and the second abutment 38 cooperate to bend the alloy strip 5 along the angle of the rounded corner 341. The bending angle can clearly show a small indentation, which allows the laser thickness detector 2 to more accurately detect the thickness of the alloy strip 5.
[0025] In this embodiment, the cleaning component 4 is divided into two groups, with its outer surfaces respectively contacting the upper and lower surfaces of the alloy strip 5 to clean dirt and debris from the upper and lower surfaces, thereby improving the accuracy of thickness inspection. The cleaning component 4 is made of a cotton-like material to avoid scratching the upper and lower surfaces of the alloy strip 5.
[0026] The working method of a high-precision alloy thin strip thickness detection device includes the following steps:
[0027] S1. The alloy strip 5 is first installed on the conveying device, and one side of the alloy strip 5 successively abuts against the lower surfaces of the first abutment 37 and the second abutment 38. At this time, the lower end face of the alloy strip 5 is located on the upper surface of the rounded corner 341.
[0028] S2. Start the first motor 31 to drive the screw 32 to rotate clockwise. The screw 32 spirally engages with the engagement hole on the moving block 33, causing the moving block 33 to drive the top block 34 and the sliding plate 35 upward. The moving block 33 slides upward inside the sliding port 12, and the sliding plate 35 slides upward under force inside the through port 361 on the limiting plate 36. As the top block 35 gradually moves upward, the rounded corner 351 abuts against the lower end face of the alloy strip 5. Under the gradual upward pressure of the top block 35, both sides of the alloy strip 5 pressed by the rounded corner 341 abut against the lower surfaces of the first abutment 37 and the second abutment 38. The part of the alloy strip 5 pressed by the rounded corner 341 is lifted upward, thereby keeping the alloy strip 5 in a taut state during the inspection process.
[0029] S3. Restart the conveying device to convey the alloy strip 5. During the conveying of the alloy strip 5, the cleaning component 4 cleans the dirt and fixed objects on the upper and lower surfaces of the alloy strip 5.
[0030] S4. After cleaning, the alloy strip 5 will be gradually conveyed to the rounded corner 341. With the cooperation of the first abutment 37 and the second abutment 38, the alloy strip 5 will be bent along the angle of the rounded corner 341. The bending angle can clearly show a small pit, which can make the laser thickness detector 2 more accurately detect the thickness of the alloy strip 5.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
