[0025] like Figure 1 and Figure 2 As shown, the COF inspection device of this embodiment includes: a feed assembly 10, a discharge assembly 20, a detection platform assembly 30 and a detection assembly 40. The detection platform assembly 30 is arranged between the feed assembly 10 and the discharge assembly 20, and the detection platform assembly 30 includes a detection platform 31, and the height of the detection platform 31 is different along the direction from the discharge assembly 20 to the feed assembly 10. The detection assembly 40 is arranged corresponding to the detection platforms 31 with different heights.

[0026] By applying the technical solution of this embodiment, the height of the detection platform 31 is set to be different along the direction from the discharge assembly 20 to the feed assembly 10, so that the detection platform 31 of the technical solution of this embodiment occupies less area than the flat detection platform in the direction from the discharge assembly 20 to the feed assembly 10, which is convenient for setting up the chip-on-film detection device in places with small space. The technical solution of this embodiment effectively solves the problem of large occupied area of ​​chip-on-film detection in the prior art.

[0027] like Figure 1 As shown, in the technical solution of this embodiment, the detection platform assembly 30 includes a detection platform mounting seat 32, and there are multiple detection platforms 31, and multiple detection platforms 31 are arranged on the detection platform mounting seat 32. The arrangement of the detection platform mounting seat 32 facilitates the installation of multiple detection platforms 31, and the structure of multiple detection platforms 31 makes the detection platform 31 more flexible according to the layout of the space. It should be noted that the detection platform 31 can also be set as one, for example, one detection platform 31 is an integral arc.

[0028] like Figure 1 As shown, in the technical solution of this embodiment, in the direction from the discharge assembly 20 to the feed assembly 10, the detection platform mounting seat 32 has an arcuate surface, and multiple detection platforms 31 are arranged in sequence along the arcuate surface, and the detection surface of each detection platform 31 is a plane. The detection platform mounting seat 32 has an arcuate surface, so that the structure of each detection platform 31 can be set to be the same, as long as it is installed according to the arcuate surface of the detection platform mounting seat 32. After the detection platform 31 is installed, the detection surface of the detection platform 31 is set at an angle. It should be noted that the detection platform mounting seat 32 of this embodiment is a hemispherical body, which is convenient for processing.

[0029] like Figure 1 As shown, in the technical solution of this embodiment, the detection component 40 includes a plurality of detectors, and the plurality of detectors are arranged corresponding to the plurality of detection platforms 31. The plurality of detectors can respectively detect a plurality of defects, for example, one detector detects wrinkles, another detector detects damage, and other detectors detect dirt, scratches and other defects, and such a detection method is more professional. It should be noted that the side of the cover chip film can be provided with markings, such as 1mm, 2mm...50mm, 51mm... In this way, when a defect is detected, the position of the defect can be quickly located so as to take measures to overcome the defect. The plurality of detectors are arranged corresponding to the plurality of detection platforms 31, so as to ensure the detection effect, that is, the detection position of the detector will not be between the detection platform 31 and the detection platform 31.

[0030] like Figure 1As shown, in the technical solution of this embodiment, the detector is a detection camera. The technology of the detection camera is relatively mature, easy to detect, and its processing and setting costs are low. It should be noted that the detection platform component 30 also includes a display, and the detection camera is electrically connected to the display, so that the detection result visualization effect is better through the display.

[0031] like Figure 1 As shown, in the technical solution of this embodiment, there are four multiple detectors, four multiple detection platforms 31, and the four detectors are arranged in a one-to-one correspondence with the four detection platforms 31. In the direction from the discharge assembly 20 to the feed assembly 10, the four detectors include a first detector, a second detector, a third detector and a fourth detector in sequence, the first detector detects damage, the second detector detects scratches, the third detector detects dirt, and the fourth detector detects wrinkles.

[0032] like Figure 1 As shown, in the technical solution of this embodiment, the detection component 40 also includes a detection light source, and the detection light source is arranged on the detector. The arrangement of the detection light source makes the detection work not limited by the environment, for example, it can also be detected in a dark environment, and such detection effect is better. It should be noted that, as other implementations, the detection light source is arranged on the detection platform component 30, so that defects are more easily found by light passing through the chip-on-film.

The two guide roller structures 33 guide the chip-on-chip film so that the chip-on-chip film can move better along the predetermined track. The setting of the guide roller 331 can greatly reduce friction and wear.

[0034] like Figure 1 As shown, in the technical solution of this embodiment, the chip-on-film detection device further includes a tensioning wheel assembly 50, which is arranged between the feed assembly 10 and the discharge assembly 20. The arrangement of the tensioning wheel assembly 50 can adjust the tensioning force of the chip-on-film. The tensioning wheel assembly 50 adopts a wheel structure, which further reduces the friction and wear of the chip-on-film.

[0035] like Figure 1As shown, in the technical solution of this embodiment, the tension wheel assembly 50 includes a first tension wheel structure 51 and a second tension wheel structure 52. The first tension wheel structure 51 is arranged between the discharge assembly 20 and the detection platform assembly 30, and the second tension wheel structure 52 is arranged between the feed assembly 10 and the detection platform assembly 30. The first tension wheel structure 51 includes four tension wheels: a first tension wheel, a second tension wheel, a third tension wheel and a fourth tension wheel. The first tension wheel and the second tension wheel are arranged at the same height. The third tension wheel is located between the first tension wheel and the second tension wheel and is lower than the first tension wheel. The fourth tension wheel is close to the detection platform assembly 30. After the chip-on-film comes out of the discharge assembly 20, it cooperates with the side of the first tension wheel facing the second tension wheel, then cooperates with the bottom side of the third tension wheel, then cooperates with the side of the second tension wheel facing the first tension wheel, and then cooperates with the side of the fourth tension wheel away from the second tension wheel, and then cooperates with the detection platform assembly 30. The second tensioning wheel includes three tensioning wheels: the fifth tensioning wheel, the sixth tensioning wheel and the seventh tensioning wheel. The fifth tensioning wheel and the seventh tensioning wheel have the same height. The sixth tensioning wheel is located between the fifth tensioning wheel and the seventh tensioning wheel and is lower than the fifth tensioning wheel. The specific matching method is as follows: Figure 1 It should be noted that the sixth tension wheel and the third tension wheel can be rotatably mounted on their respective rotating shafts, and the above-mentioned rotating shafts are mounted on the mounting frame through springs, that is, the sixth tension wheel and the third tension wheel can be moved upward and compressed to adjust the tensioning force.

[0036] It should be noted that if Figure 2 As shown, the feeding assembly 10 includes a servo motor 11, a transmission gear 12 and a reel 13. The reel 13 is rotatably mounted on a mounting frame.
