Description

Technical Field

[0001] This utility model relates to the field of testing devices, and in particular to a surface testing device for aluminum foil blanks. Background Technology

[0002] Inspection devices are equipment or systems used for measurement and monitoring, widely applied in industries such as manufacturing, medicine, scientific research, environmental protection, and safety. Their core function is to provide accurate and reliable data to ensure quality, safety, efficiency, and compliance. In manufacturing, inspection devices are used to monitor product dimensions, defects, and performance in real time to ensure compliance with quality standards. Surface inspection of aluminum foil blanks is a critical step in the aluminum foil production process, directly impacting the quality, performance, and market competitiveness of the final product. Identifying non-metallic inclusions or metallic contaminants in aluminum foil blanks through surface scanning or spectral analysis allows for early defect detection, reducing scrap rates in subsequent rolling processes and preventing resource waste. However, in optical or laser inspection, if aluminum foil blanks are not securely clamped, even slight vibrations or shifts can distort the inspection data.

[0003] Chinese Patent CN221224604U discloses a device for detecting surface defects and stains on aluminum foil. It uses an optical sensor to detect the surface of aluminum foil to analyze whether there are defects and oil stains on the surface of aluminum foil. However, when detecting aluminum foil blanks of different sizes, there is a problem that it is inconvenient to clamp and fix the aluminum foil blanks of different sizes. In view of this, an aluminum foil blank surface detection device is provided. Utility Model Content

[0004] The main objective of this invention is to provide an aluminum foil blank surface inspection device to solve the problem in related technologies where it is inconvenient to clamp and fix aluminum foil blanks of different sizes when inspecting them.

[0005] To achieve the above objectives, according to one aspect of the present invention, an aluminum foil blank surface inspection device is provided, comprising a base, an mounting frame fixedly installed in the middle of the upper surface of the base, a sliding groove extending through the upper surface of the mounting frame, an inspection head slidably installed in the sliding groove, two sets of inclined grooves symmetrically opened on the inner sidewall of the mounting frame near the lower edge, and further comprising: a clamping block, the clamping block being snapped into the inclined groove, a protrusion fixedly installed on one side of the clamping block, a spring fixedly installed on the lower surface of the protrusion, and a pressure block fixedly installed on the other end of the spring, wherein the aluminum foil to be inspected is clamped and fixed by the clamping block and the pressure block.

[0006] Furthermore, each set of inclined slots has two slots. The two inclined slots on the same side are symmetrical about the midpoint of the side wall of the mounting frame. The inclined slots slope from the midpoint of the side wall of the mounting frame towards the edge. The clamping block has a trapezoidal structure, and the inclined surface of the clamping block fits tightly with the inclined surface of the inclined slot.

[0007] Furthermore, the inclined groove sidewall is symmetrically provided with several limiting grooves, and the clamping block sidewall is symmetrically fixedly installed with several limiting blocks, which are slidably installed in the limiting grooves.

[0008] Furthermore, support blocks are symmetrically installed on both sides of the mounting frame, and a connecting groove with a connecting inclined groove is opened on the side wall of the mounting frame. A connecting rod is fixedly installed on the inclined surface of the clamping block. The connecting rod is perpendicular to the inclined surface of the clamping block and is slidably installed in the connecting groove.

[0009] Furthermore, a fixing screw hole is provided at one end of the connecting rod, and a fixing bolt is installed in the internal thread of the fixing screw hole.

[0010] Furthermore, a tightening screw hole is provided through the upper surface of the protrusion, and a tightening bolt is installed in the thread of the tightening screw hole. One end of the tightening bolt is pressed against the pressure block. The pressure block is made of flexible material and has rounded corners at its edges.

[0011] Furthermore, a mounting block is slidably installed in the sliding groove. The mounting block has a T-shaped structure. The detection head is fixedly installed on the lower surface of the mounting block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This aluminum foil blank surface inspection device is equipped with a mounting frame. The inner side wall of the mounting frame has two sets of inclined grooves symmetrically opened on the left and right sides. Each set of inclined grooves has two grooves. The two inclined grooves on the same side are symmetrical about the midpoint of the side wall of the mounting frame, and the inclined grooves slope from the midpoint of the side wall of the mounting frame towards the edge. A clamping block is slidably installed in the inclined groove. A connecting groove is opened on the side wall of the mounting frame to connect the inclined groove. A connecting rod is fixedly installed on one side of the clamping block. The connecting rod is slidably installed in the connecting groove and passes through the connecting groove to the outside. The connecting rod pushes the clamping block to slide along the inclined groove to change the distance between the clamping blocks on both sides. The clamping block clamps aluminum foil blanks of different widths to prevent the aluminum foil blanks from shifting and vibrating during inspection, which would affect the inspection effect.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] This embodiment provides an aluminum foil blank surface inspection device, including a base 1, an installation frame 2 fixedly installed in the middle of the upper surface of the base 1, a sliding groove 21 through the upper surface of the installation frame 2, an inspection head 212 slidably installed in the sliding groove 21, two sets of inclined grooves 23 symmetrically opened on the inner side wall of the installation frame 2 near the lower edge, and also includes: a clamping block 3, the clamping block 3 is snapped into the inclined groove 23, a protrusion 33 is fixedly installed on one side of the clamping block 3, a spring 331 is fixedly installed on the lower surface of the protrusion 33, and a pressure block 34 is fixedly installed on the other end of the spring 331, the aluminum foil to be inspected is clamped and fixed by the clamping block 3 and the pressure block 34;

[0027] like Figure 2 , Figure 3 , Figure 5 As shown, each set of inclined grooves 23 has two sections. The two inclined grooves 23 on the same side are symmetrical about the midpoint of the side wall of the mounting frame 2, and the inclined grooves 23 slope from the midpoint of the side wall of the mounting frame 2 towards the edge (e.g., Figure 5As shown), the clamping block 3 has a trapezoidal structure, and the inclined surface of the clamping block 3 is in close contact with the inclined surface of the inclined groove 23;

[0028] like Figure 2 As shown, a number of limiting grooves 231 are symmetrically opened on the side wall of the inclined groove 23, and a number of limiting blocks 32 are symmetrically fixedly installed on the side wall of the clamping block 3. The limiting blocks 32 are slidably installed in the limiting grooves 231, and the clamping block 3 slides along the limiting grooves 231 through the limiting blocks 32.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, support blocks 22 are symmetrically installed on both sides of the mounting frame 2. A connecting groove 232 connecting the inclined groove 23 is opened on the side wall of the mounting frame 2. A connecting rod 31 is fixedly installed on the inclined surface of the clamping block 3. The connecting rod 31 is perpendicular to the inclined surface of the clamping block 3. The connecting rod 31 is slidably installed in the connecting groove 232. By pushing the connecting rod 31, the clamping block 3 is driven to slide along the inclined groove 23. When the clamping block 3 slides along the inclined groove 23, one end of the clamping block 3 extends out of the inclined groove 23. The clamping block 3 presses against the side wall of the aluminum foil blank to fix aluminum foil blanks of different sizes. It is more labor-saving to clamp the block 3 when the connecting rod 31 perpendicular to the inclined surface of the clamping block 3 is pushed.

[0030] like Figure 1 , Figure 2 , Figure 4 As shown, a fixing screw hole 311 is provided through one end of the connecting rod 31. A fixing bolt is installed in the fixing screw hole 311. Tightening the fixing bolt in the fixing screw hole 311 tightens it against the upper surface of the support block 22 to fix the position of the connecting rod 31.

[0031] like Figure 4 As shown, a tightening screw hole is provided through the upper surface of the protrusion 33. A tightening bolt 332 is installed in the thread of the tightening screw hole. One end of the tightening bolt 332 presses against the pressure block 34. The pressure block 34 is made of flexible material and has rounded corners at its edge. Rotating the tightening bolt 332 presses against the upper surface of the pressure block 34, thereby pushing the pressure block 34 against the edge of the upper surface of the aluminum foil blank to fix aluminum foil blanks of different sizes and prevent the aluminum foil blank from shifting and vibrating during testing, which would affect the test data. At this time, the spring 331 is stretched. When it is necessary to remove the aluminum foil blank, after loosening the tightening bolt 332, the spring 331 returns to its original position to drive the pressure block 34 to move upward, so as to facilitate the removal of the aluminum foil blank.

[0032] like Figure 1 , Figure 2As shown, a mounting block 211 is slidably installed in the sliding groove 21. The mounting block 211 has a T-shaped structure. The detection head 212 is fixedly installed on the lower surface of the mounting block 211. A tightening screw hole 213 is opened on the upper surface of the mounting block 211. A tightening bolt is installed in the tightening screw hole 213. The detection head 212 is driven to slide along the sliding groove 21 by the mounting block 211 to detect the surface of the aluminum foil blank. Tightening the tightening bolt in the tightening screw hole 213 tightens the upper surface of the mounting bracket 2 to fix the position of the detection head 212. The detection head 212 detects defects such as scratches, holes, oil stains, oxidation spots, and wrinkles on the surface of the aluminum foil through optical or electromagnetic technology.

[0033] In practical use, the aluminum foil blank is placed under the mounting frame 2. By pushing the connecting rod 31, the clamping block 3 slides along the inclined groove 23. The inclined surface of the trapezoidal clamping block 3 fits against the inclined groove 23. When the clamping block 3 slides along the inclined groove 23, one end of the clamping block 3 extends out of the inclined groove 23, and the clamping block 3 presses against the side wall of the aluminum foil blank. A protrusion 33 is fixedly installed on one edge of the clamping block 3. A spring 331 is fixedly installed on the lower surface of the protrusion 33. A pressure block 34 is fixedly installed on the other end of the spring 331. A tightening screw hole is opened on the upper surface of the protrusion 33. A tightening bolt 332 is installed in the internal thread of the rotating tightening screw hole. The tightening bolt 332 presses against the upper surface of the pressure block 34. The pressure block 34 is pushed by the tightening bolt 332, and the pressure block 34 presses against the edge of the upper surface of the aluminum foil blank to fix aluminum foil blanks of different sizes. This prevents the aluminum foil blank from shifting and vibrating during testing, which would affect the test data. When the aluminum foil blank needs to be removed, the spring 331 resets to drive the pressure block 34 to move upward, so that the aluminum foil blank can be removed. The detection head 212 is driven to slide along the sliding groove 21 by the mounting block 211 to test the surface of the aluminum foil blank.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
