Description

A testing device for calendered products Technical Field

[0001] This application relates to the technical field of testing equipment, and in particular to a testing device for calendered products. Background Technology

[0002] After calendering products, such as gold foil, are completed, they need to be tested for data such as flatness. If the data obtained from the test has a large error compared with the data required for production, the calendering equipment needs to be adjusted.

[0003] Currently, a calendered product inspection device includes a main body with a movable block slidably connected to it. A drive assembly, which can be a motor screw or a cylinder, is mounted on the main body and connected to the movable block. A placement plate is mounted on the movable block. A support block is fixed to the main body, and a laser head is fixed to the support block. A receiving camera is placed on one side of the laser head. The light emitted from the laser head illuminates the calendered product, and the receiving camera receives the light emitted by the calendered product. The receiving camera transmits the signal to a computer for processing and analysis, generating intuitive data that is easy for operators to view.

[0004] When the calendered product is uneven, such as having obvious uphill or downhill slopes, the receiving camera cannot properly receive the light reflected from the calendered product, which will lead to inaccurate test data. Summary of the Invention

[0005] To improve the accuracy of testing, this application provides a testing device for calendered products.

[0006] This application provides a calendered product testing device, which adopts the following technical solution:

[0007] A rolling product testing device includes a main body, a support block, a moving mechanism, and a testing mechanism. The support block is disposed on the main body. The testing mechanism includes a first connecting block, a second connecting block, a third connecting block, a laser head, and a receiving camera. The first connecting block is disposed on the main body, the second connecting block is disposed on the first connecting block, and the laser head is disposed on the second connecting block. The third connecting block is disposed on the first connecting blocks on both sides of the second connecting block. The receiving camera is disposed on the third connecting block, and both the receiving camera and the laser head are located above the support block. The moving mechanism is disposed on the main body, and the support block or the first connecting block is connected to the moving mechanism.

[0008] By adopting the above technical solution, the calendered product is placed on the support block, and the laser head shines a laser beam onto the calendered product. The calendered product reflects the laser beam, and the receiving cameras on both sides of the laser head receive the reflected laser beam. In this way, even if the calendered product has obvious ups and downs, the receiving cameras on both sides of the laser head can still receive the emitted laser beam well. Then, the moving component is activated, which drives the first connecting block or the support block to move, causing the first connecting block to move relative to the support block, so that the detection mechanism can detect the entire calendered product. Therefore, the detection mechanism can improve the detection accuracy.

[0009] Optionally, both the second connecting block and the third connecting block are provided with an adjustment mechanism. The adjustment mechanism includes an adjustment block, a first slider, a positioning bolt, and a mounting assembly. The adjustment block abuts against the second connecting block or the third connecting block. The laser head and the receiving camera are both mounted on the adjustment block through the mounting assembly. The second connecting block and the third connecting block are provided with a sliding groove. The first slider is slidably disposed in the sliding groove. The first slider is provided with a first threaded hole. The adjustment block is provided with a first through hole. The positioning bolt passes through the first through hole and is threadedly connected to the first threaded hole.

[0010] By adopting the above technical solution, the adjusting block is first made to stop pressing against the third or second connecting block, while the positioning bolt remains threadedly connected to the first threaded hole; then the adjusting block is moved, and the positioning bolt on the adjusting block will drive the first slider to slide in the groove; after the position of the adjusting block is determined, the positioning bolt is rotated to make the adjusting block press against the second or third connecting block; the adjustable adjusting block can change the position of the laser head on the second connecting block and the position of the receiving camera on the third connecting block, thereby improving applicability.

[0011] Optionally, the mounting assembly includes a mounting block, a first mounting bolt, and a second mounting bolt. The laser head and the receiving camera have a second threaded hole, and the mounting block has a second through hole. The first mounting bolt passes through the second through hole and is threadedly connected to the second threaded hole. The adjusting block has a third threaded hole, and the mounting block has a third through hole. The second mounting bolt passes through the third through hole and is threadedly connected to the third threaded hole.

[0012] By adopting the above technical solution, the laser head or receiving camera is first brought into contact with the mounting block, and then the first mounting bolt is threaded through the second through hole and connected to the second threaded hole; then the mounting block is brought into contact with the adjusting block, so that the laser head or receiving camera will move when the adjusting block moves.

[0013] Optionally, both the second connecting block and the third connecting block are provided with an angle adjustment mechanism. The angle adjustment mechanism includes a fourth connecting block, an adjustment block, a mold spring, an adjustment screw, and a limiting block. Both the second connecting block and the third connecting block are provided with the fourth connecting block. One end of the mold spring is connected to the third connecting block and the other end is connected to the adjustment block. The laser head and the receiving camera are both provided on the adjustment block. The adjustment block has a fourth through hole and a groove communicating with the fourth through hole. The fourth connecting block has a fourth threaded hole. The adjustment screw is provided on the limiting block. The end of the adjustment screw away from the limiting block passes through the groove, the fourth through hole, and the mold spring in sequence and is threadedly connected to the fourth threaded hole. The limiting block is located in the groove.

[0014] By adopting the above technical solution, rotating the limiting block will cause the adjusting screw to rotate, and the length of the threaded connection between the adjusting screw and the fourth threaded hole will change; the force of the mold spring restoring its elastic deformation will cause the adjusting block to move. When the compression length of the mold spring is different, the angle of the adjusting block relative to the fourth connecting block will change. In this way, the angle of the laser head relative to the second connecting block and the angle of the receiving camera relative to the third connecting block can change, thereby improving applicability.

[0015] Optionally, the first connecting block is provided with a rotating mechanism connected to the third connecting block. The rotating mechanism includes a support block, a rotating shaft, and a locking component. The support block is disposed on the first connecting block, the rotating shaft is rotatably disposed on the support block, and the third connecting block is disposed on the rotating shaft. The locking component is disposed on the support block and connected to the rotating shaft.

[0016] By adopting the above technical solution, the third connecting block is rotated, which drives the rotating shaft to rotate; when the angle of the third connecting block relative to the first connecting block is determined, the locking component locks the rotating shaft; the set rotation mechanism can improve applicability.

[0017] Optionally, the support block has a cavity and a fifth threaded hole communicating with the cavity. The locking assembly includes a locking block and a locking bolt. The locking block is slidably disposed in the cavity and can abut against the rotating shaft. One end of the locking bolt is rotatably connected to the locking block and the other end passes through the fifth threaded hole. The locking bolt is threadedly connected to the fifth threaded hole.

[0018] By adopting the above technical solution, once the position of the third connecting block is determined, the locking bolt is rotated, and the locking bolt drives the locking block to move, so that the locking block abuts against the rotating shaft.

[0019] Optionally, the moving mechanism includes a slide rail, a second slider, a moving block, and a moving component. The slide rail is disposed on the main body, the second slider is slidably disposed on the slide rail, the moving block is connected to the second slider, and the first connecting block is disposed on the moving block. The moving component is disposed on the main body and connected to the moving block.

[0020] By adopting the above technical solution, the moving component is activated, which drives the moving block to move. The moving block then drives the second slider to slide on the slide rail. When the moving block moves, it drives the first connecting block to move, thereby causing the first connecting block to move relative to the supporting block.

[0021] Optionally, the moving component includes a moving motor and a moving lead screw. The moving motor is mounted on the main body, and the moving lead screw is mounted on the output shaft of the moving motor. The moving lead screw passes through the moving block and is threadedly connected to the moving block.

[0022] By adopting the above technical solution, the moving motor is started, and the output shaft of the moving motor drives the moving lead screw to rotate, which in turn drives the moving block to move.

[0023] Optionally, the main body is provided with a limiting mechanism, which includes a limiting block and a limiting rubber block. The limiting block is disposed on the main body, the limiting rubber block is disposed on the limiting block, and the movable block can abut against the limiting rubber block.

[0024] By adopting the above technical solution, when the moving block moves to the end of the main body, it will abut against the limiting rubber block, reducing the phenomenon of the moving block directly colliding with the main body and providing protection for the moving block.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0045] When it is necessary to adjust the angle of the third connecting block 33 relative to the first connecting block 31, rotate the third connecting block 33, and the rotating shaft 62 on the third connecting block 33 will rotate; after the position of the third connecting block 33 is determined, rotate the locking bolt 632, and the locking bolt 632 will drive the locking block 631 to move in the cavity, so that the locking block abuts against the rotating shaft 62 located in the cavity, thereby fixing the position of the rotating shaft 62 and the third connecting block 33.

[0046] Referring to Figures 1 and 4, both the second connecting block 32 and the third connecting block 33 are provided with sliding grooves 331. In this embodiment, the adjustment mechanism 4 on the third connecting block 33 and the adjustment mechanism 4 on the second connecting block 32 have the same structure. This embodiment will be described using the adjustment mechanism 4 on the third connecting block 33. The adjustment mechanism 4 includes an adjustment block 41 that abuts against the third connecting block 33, and the adjustment block 41 has a first through hole. A first slider 42 is slidably connected in the sliding groove 331, and the first slider 42 has a first threaded hole.

The limiting block 55 will drive the adjusting screw 54 to rotate, and the length of the threaded connection between the adjusting screw 54 and the fourth threaded hole will change. The force of the mold spring 53 restoring its elastic deformation will drive the adjusting block 52 to move. When the compression length of one mold spring 53 on the fourth connecting block 51 is different from the compression length of the two mold springs 53 on the other side, the angle of the adjusting block 52 relative to the fourth connecting block 51 will change.
