A ball bearing 2933 is provided at the bottom end of each of the two moving columns 2931 and is pressed on the slope 2911. A first through hole 2934 is provided on the sinking plate 293 to expose the carrier tape 8 and the detection camera 31 (please refer to Figure 5 ) can be used for photographic measurement, the first light source 321 (please refer to Figure 5 ) can be irradiated onto the carrier tape 8 through the first through hole 2934.

[0077] The first through hole 2934 corresponds to the second through hole 51, and the axis of the first through hole 2934, the axis of the second through hole 51, the light emitted by the first light source 321, and the second light source 322 (see Figure 5 ) and the lens axis of the detection camera 31 are located on the same straight line.

[0078] When the two clamping plates 291 move away from each other, the moving column 2931 slides on the slope 2911 through the ball bearing 2933, so that the sinking plate 293 moves downward on the fixed column 285, so that the height of the sinking plate 293 is reduced, and the pressure column 2932 presses on the carrier 8 to prevent the carrier 8 from tilting or arching; when the two clamping plates 291 move relative to each other, the moving column 2931 slides on the slope 2911 through the ball bearing 2933, so that the sinking plate 293 moves upward on the fixed column 285, so that the height of the sinking plate 293 is increased. At this time, the clamping plate 291 covers the channel 28 to prevent the carrier 8 from tilting or arching.

[0079] Please refer to Figures 2 to 6 , which is a schematic diagram of the structure of a carrier detection system 100 according to an embodiment of the present application. The method of using the carrier detection system 100 is as follows:

[0080] The control module 1 receives the identification code data on the carrier tape 8 (the identification code may be a product number, a barcode or a QR code, and the identification code data may be manually entered or recognized by the carrier tape detection system 100 through the detection camera 31);

[0081] When the carrier tape 8 enters the carrier tape conveying module 2, the control module 1 receives the position data of the carrier tape 8 collected by the feed sensor 26;

[0082] The control module 1 determines whether a carrier tape 8 enters the carrier tape conveying module 2 according to the position data of the carrier tape 8 collected by the feed sensor 26;

[0083] When the carrier tape 8 enters the carrier tape conveying module 2, the control module 1 controls the roller driving device 25 to rotate the second roller 22 and the fourth roller 24, controls the first moving device 212 to press down the first roller 21, and controls the second moving device 232 to press down the third roller 23;

[0084] The control module 1 receives the position data of the carrier belt 8 collected by the discharge sensor 27;

[0085] The control module 1 determines whether the carrier belt 8 has reached the third roller 23 according to the position data of the carrier belt 8 collected by the discharge sensor 27;

[0086] When the carrier tape 8 reaches the third roller 23, the control module 1 controls the first moving device 212 to move the first roller 21 upward, controls the third moving device 42 to press the thickness sensor 41 downward; controls the fourth moving device 292 to move the two clamping plates 291 away from each other; controls the hole detection sensor 33 to collect and transmit data, controls the thickness sensor 41 to start collecting and transmitting data; controls the detection camera 31 to start collecting and transmitting data;

[0087] The control module 1 again receives the position data of the carrier belt 8 collected by the feed sensor 26;

[0088] The control module 1 determines whether the carrier tape 8 has entered the carrier tape conveying module 2 and has walked out of the first roller 21 according to the carrier tape 8 position data collected by the feed sensor 26;

[0089] When the carrier tape 8 enters the carrier tape conveying module 2 and has gone out of the first roller 21, the control module 1 controls the thickness sensor 41 to stop collecting data and transmitting data; and controls the detection camera 31 to stop collecting data and transmitting data;

[0090] The control module 1 again receives the position data of the carrier belt 8 collected by the discharge sensor 27;

[0091] According to the position data of the carrier belt 8 collected by the discharge sensor 27, the control module 1 determines whether the carrier belt 8 has reached the third roller 23 and has exited the third roller 23;

[0092] When the carrier tape 8 reaches the third roller 23 and has moved out of the third roller 23, the control module 1 counts for two seconds and then controls the third moving device 42 to move the thickness sensor 41 upward, controls the second moving device 232 to move the third roller 23 upward, and controls the fourth moving device 292 to move the two clamping plates 291 relative to each other.

[0093] The control module 1 generates a detection report of the carrier tape 8 according to the data collected by the thickness sensor 41, the data collected by the hole detection sensor 33, the data collected by the detection camera 31, and the identification code of the carrier tape 8;

[0094] The control module 1 determines whether the thickness and the outer dimensions of the carrier tape 8 are qualified according to the inspection report of the carrier tape 8;

[0095] When the size of the carrier tape 8 is unqualified, the control module 1 prompts an alarm signal (the prompt alarm signal can be a pop-up window warning through the human-computer interaction interface 11, or it can be an alarm sound or an alarm LED light);

[0096] When the size of the carrier tape 8 is qualified, the control module 1 automatically stores the detection report.

[0097] The method of using the carrier 8 detection system also includes:

[0098] The control module 1 receives a signal indicating whether the carrier tape 8 is transparent or not, or manually inputs information indicating whether the carrier tape 8 is transparent or not.

[0099] When the carrier tape 8 is transparent, the control module 1 controls the second light source 322 to turn on and controls the first light source 321 to turn off;

[0100] When the carrier tape 8 is non-transparent, the control module 1 controls the first light source 321 to turn on, and controls the second light source 322 to turn off.

[0101] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
