Description

Technical Field

[0001] This utility model belongs to the field of visual inspection technology, specifically relating to a linear visual inspection machine. Background Technology

[0002] Linear vision inspection machines use a conveyor belt to move materials in a straight line and work with a vision inspection mechanism to perform optical inspection on the materials. This allows for efficient inspection of the outer tubes of materials. However, in actual use, the vision inspection machine can only inspect the parts of the material corresponding to the lens position. Currently, multi-angle placement and conveying can enable comprehensive visual inspection of materials. While multiple planar materials can be inspected at different angles by placing them at different angles, the curved surfaces on the sides of iron pillars have high similarity. After the materials are unloaded, it is difficult for workers to distinguish the parts that have already been inspected, which makes it inconvenient to perform comprehensive visual inspection of the iron pillars. Utility Model Content

[0003] This utility model provides a linear vision inspection machine, which can simultaneously transport an iron column in a straight line and rotate the iron column. In conjunction with the reflection of the side end mirror on the side end surface of the iron column, the vision inspection mechanism can perform all-round inspection of the outer wall of the iron column.

[0004] This utility model provides the following technical solution: a linear vision inspection machine, including a workbench and a vision inspection mechanism. Two corresponding annular circulating conveyor belts are installed above the workbench. Several iron column engaging slots are fixedly connected to the outer wall of the annular circulating conveyor belts. A hard friction resistance plate is provided between the two annular circulating conveyor belts. Iron column magnets are provided on both sides of the hard friction resistance plate. Side-end reflective mirrors are installed on opposite sides of the two annular circulating conveyor belts. The two side-end reflective mirrors are tilted in opposite directions.

[0005] Among them, an inner lubrication pad layer is fixedly connected to the inner wall of several of the iron pillar locking slot blocks.

[0006] The rigid friction resistance plate is fixedly connected to a friction pad at its top, and the iron column is fixedly connected to a high-roughness isolation pad at its bottom magnet.

[0007] The hard friction resistance plate and the lower magnet of the iron column are both fixedly connected to side support frames at both ends, and the side support frames are fixedly connected to the top of the workbench frame.

[0008] The bottom end of the side reflector is fixedly connected to a support rod, which is fixedly connected to the top of the workbench.

[0009] The tops of the bonding resistance pad and the high-roughness isolation pad are flush, and the bottom of the side reflector is lower than the top of the annular circulating conveyor belt.

[0010] The surface friction coefficient of the adhesive resistance pad is greater than that of the high-roughness isolation pad and the inner lubrication pad layer.

[0011] The beneficial effects of this utility model are as follows: After the iron column is limited by the annular circulating conveyor belt and the iron column locking groove block, the iron column is driven to move laterally. The downward force is applied to the iron column by the magnet attracted by the iron column. With the resistance applied to the iron column by the hard friction resistance plate and the contact resistance pad when they are relative to the iron column, the iron column can be transported in a straight line while being driven to rotate. With the reflection of the side end mirror on the side end surface of the iron column, the visual inspection mechanism can perform all-round inspection of the outer wall of the iron column.

[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] Please see Figures 1-4 The present invention provides the following technical solution: a linear vision inspection machine, including a workbench 1 and a vision inspection mechanism 11. Two corresponding annular circulating conveyor belts 2 are installed on the upper part of the workbench 1. Several iron column engaging slots 21 are fixedly connected to the outer wall of the annular circulating conveyor belts 2. A hard friction resistance plate 3 is provided between the two annular circulating conveyor belts 2. Iron column lower magnets 31 are provided on both sides of the hard friction resistance plate 3. Side end reflective mirrors 4 are installed on the opposite side of the two annular circulating conveyor belts 2. The two side end reflective mirrors 4 are set in opposite directions.

[0019] In this implementation scheme: the annular circulating conveyor belt 2 is connected to the drive motor via a drive shaft. The two annular circulating conveyor belts 2 rotate synchronously under the action of the drive motor. The iron column to be tested is placed in the iron column locking slot 21, which limits the iron column and prevents it from moving laterally relative to the annular circulating conveyor belt 2. After the annular circulating conveyor belt 2 and the iron column locking slot 21 drive the iron column to move laterally a certain distance together, the iron column comes into contact with the contact resistance pad 32. Under the action of static friction between the contact resistance pad 32 and the iron column, the contact resistance pad 32 and the iron column roll relative to each other, causing the iron column to... The column rotates within the iron column engaging slot 21, enabling the iron column to be transported linearly while simultaneously rotating. The vision inspection mechanism 11 can observe different positions on the side of the iron column. In conjunction with the reflection of the side end mirror 4 on the side end face of the iron column, the vision inspection mechanism 11 can perform all-round inspection of the outer wall of the iron column. The two side end mirrors 4 reflect the images of the two end faces of the iron column respectively. The tilt angle of the side end mirrors 4 is set according to the installation position of the vision inspection mechanism 11 so that the images reflected by the side end mirrors 4 can be captured by the lens of the vision inspection mechanism 11.

[0020] Several iron column engaging slot blocks 21 have an inner lubrication pad 22 fixedly connected to their inner walls. By setting the inner lubrication pad 22, the iron column engaging slot block 21 can be prevented from directly contacting the iron column, thereby reducing the resistance encountered when the iron column rotates, so that the iron column can rotate smoothly.

[0021] The top of the hard friction resistance plate 3 is fixedly connected to the contact resistance pad 32, and the top of the magnet 31 at the bottom of the iron column is fixedly connected to the high roughness isolation pad 33. By setting the contact resistance pad 32, the roughness of the surface of the hard friction resistance plate 3 can be increased, so that the iron column can be subjected to greater static friction when it moves laterally, so that the iron column can rotate smoothly and avoid the contact resistance pad 32 and the iron column from forming sliding friction, which would prevent the iron column from rotating.

[0022] Both ends of the hard friction resistance plate 3 and the iron column lower magnet 31 are fixedly connected to side support frames 34, which are fixedly connected to the top of the workbench frame 1; by setting the side support frames 34, the hard friction resistance plate 3 and the iron column lower magnet 31 can be supported.

[0023] A support rod 41 is fixedly connected to the bottom end of the side reflector 4, and the support rod 41 is fixedly connected to the top of the workbench 1. By setting the support rod 41, the side reflector 4 can be supported so that the side reflector 4 is stably in an inclined state. Multiple support rods 41 can be installed at the bottom end of the side reflector 4 to increase the stability of the support for the side reflector 4.

[0024] The tops of the bonding resistance pad 32 and the high-roughness isolation pad 33 are flush, and the bottom of the side reflector 4 is lower than the top height of the annular circulating conveyor belt 2. The tops of the bonding resistance pad 32 and the high-roughness isolation pad 33 are flush, so that the bonding resistance pad 32 can fit with the iron column and prevent the iron column from losing contact with the bonding resistance pad 32.

[0025] The surface friction coefficient of the contact resistance pad 32 is greater than that of the high-roughness isolation pad 33 and the inner lubrication pad layer 22. The high surface friction coefficient of the contact resistance pad 32 makes the static friction between the contact resistance pad 32 and the iron column greater than the sliding friction between the high-roughness isolation pad 33 and the inner lubrication pad layer 22 and the iron column, so as to avoid the contact resistance pad 32 sliding relative to the iron column.

[0026] The working principle and usage process of this utility model are as follows: The iron column to be inspected is placed in the iron column locking slot 21, which limits the iron column and prevents it from moving laterally relative to the annular circulating conveyor belt 2. After the annular circulating conveyor belt 2 and the iron column locking slot 21 drive the iron column to move laterally a certain distance, the iron column comes into contact with the contact resistance pad 32. Under the action of static friction between the contact resistance pad 32 and the iron column, the contact resistance pad 32 and the iron column roll relative to each other, causing the iron column to rotate within the iron column locking slot 21. This achieves linear transport of the iron column while driving it to rotate. The visual inspection mechanism 11 can observe different positions on the side of the iron column. With the reflection of the side end mirror 4 on the side end of the iron column, the visual inspection mechanism 11 can perform all-round inspection of the outer wall of the iron column.
