[0002] The infrared thickness automatic detection and rejection device is an automated device that integrates infrared thickness measurement technology. It can detect the thickness of the product in real time and automatically reject it from the conveyor line when it detects that the product thickness is unqualified.

[0003] Although existing infrared automatic thickness detection and rejection equipment can perform real-time thickness detection on each product on the conveyor line and accurately reject unqualified products, thereby improving production efficiency and product quality, it still has the following shortcomings:

When the previously damaged guide shell 106 is repaired or replaced, it can be reset, that is, qualified products and unqualified products are transported by quickly switching to the spare channel, thereby avoiding the situation where production has to be suspended when the guide shell 106 is damaged, which leads to an extension of the production gap.

[0044] The effect and working principle of the entire mechanism are as follows:

[0045] In the preparation stage, first use the prepared crane to move the entire infrared thickness automatic detection and rejection equipment to the place where it is required to be used, then adjust the angle of the entire equipment until the feeding end of the conveyor 119 is connected to the unloading end of the unloading equipment of the product to be detected, then electrically connect the controller 108, the two motor drivers 109, the infrared ranging sensor 117, the dual-axis motor 209 and the conveyor 119 in accordance with the drawing requirements and electrical safety connection guidelines, then connect the controller 108 to the power supply equipment through the prepared power cord, then start the controller 108 to enter the initial interface, then set various parameters such as the motor speed of the conveyor 119 and the speed of the dual-axis motor 209, and finally input the judgment value into the controller 108 (the value obtained by subtracting the thickness value of the qualified product from the distance between the top of the conveyor belt of the conveyor 119 and the detection end face of the infrared ranging sensor 117);

[0046] During the detection phase, when it is necessary to detect the thickness of the product (sheet-shaped and opaque) delivered by the unloading equipment, the controller 108 and the corresponding motor driver 109 are first used to start the conveyor 119. At this time, the product on the conveyor belt of the conveyor 119 will continue to be transported toward its discharge end. When the product reaches the designated position (product thickness detection area), the controller 108 will briefly pause the conveyor 119 and then start the infrared distance sensor 117. The activated infrared distance sensor 117 will then measure the thickness of the product arriving at the designated position and transmit the detected thickness value to the controller 108 in the form of an electrical signal. The controller 108 will then compare the received thickness value with the judgment value set in advance by the controller 108.

[0047] In the unswitched stage, when the thickness value received by the controller 108 is the same as the judgment value set in advance by the controller 108, it means that the detected product is qualified. At this time, the controller 108 will start the dual-axis motor 209 through the corresponding motor driver 109, and let its output end rotate forward. Then the started dual-axis motor 209 will drive the first round rod 211 to rotate under the cooperation of one of the connectors 210 and one of the stabilizing frames 212. Then the rotating first round rod 211 will rotate on the trapezoidal plate 201 and the fixed hole. The long rod 204, the connecting block 206, the three first pulleys 213 and the first belt (in the initial state, the first belt is in a tightened state and the second belt is in a loose state) cooperate to drive the threaded rod of the slide 110 to rotate. Then, the threaded rod of the rotating slide 110 will drive the two U-shaped blocks 118 to move toward one of the U-shaped shells 114 at the same time under the cooperation of the slide rail of the slide 110 and the two slide seats of the slide 110. At this time, one of the moving U-shaped blocks 118 will drive the inspected product to move into one of the U-shaped shells. When the product is transported away and the two U-shaped blocks 118 are reset to their original positions, the controller 108 will stop the double-axis motor 209 through the corresponding motor driver 109, and then start the conveyor 119 through the corresponding motor driver 109 to continue conveying the product, and repeat the above steps.

[0048] During the switching stage, when any one of the guide shells 106 is damaged and needs to be replaced or repaired and can no longer be used, the hand screw 203 is first turned. At this time, the rotating hand screw 203 will drive the long rod 204 with the cooperation of the hole block 202 to move downward. At the same time, the moving long rod 204 with the hole will drive the corresponding first pulley 213 and the corresponding second pulley 221 to move in position under the cooperation of the connecting block 206, the connecting rod 207, the auxiliary block 205 and the slider 214. When the long rod 204 with the hole moves to a point where it cannot move, the hand screw 203 is stopped. At this time, the first belt is in a loose state. The second belt is in a tensioned state. When the subsequent products are transported to the designated location for inspection again and the inspected products are determined to be qualified, the controller 108 will once again cooperate with the corresponding motor driver 109 to start the dual-axis motor 209 and let its output end rotate forward. At this time, the started dual-axis motor 209 will drive the second round rod 215 to rotate under the cooperation of another stabilizing frame 212 and another connector 210. Subsequently, the rotating second round rod 215 will drive the rotating rod 219 to rotate under the cooperation of the third round rod 216, the second belt and the four second pulleys 221, and the rotating rotating rod 219 will drive the connected The rotating plate 220 rotates. When the rotating plate 220 rotates to be parallel to the inner partition of the double-layer shell 218, the controller 108 will cooperate with the corresponding motor driver 109 to pause the dual-axis motor 209, and then continue to cooperate with the corresponding motor driver 109 to start the conveyor 119. At this time, starting the conveyor 119 will drive the inspected products to move. When the products are discharged from the discharge end of the conveyor 119, the products on the conveyor belt will continue to be moved to the designated area for inspection. The products discharged from the discharge end will enter the upper layer of the double-layer shell 218 through the cooperation of the rotating plate 220 and then be transported away. When the subsequent products are discharged, the conveyor 119 will continue to move to the designated area for inspection. The product is transported to the designated location for inspection again, and when the inspected product is determined to be unqualified, the controller 108 will once again cooperate with the corresponding motor driver 109 to start the dual-axis motor 209 and reverse its output end. At this time, the started dual-axis motor 209 will drive the rotating plate 220 to rotate with the cooperation of the previous linkage components until one end of the rotating plate 220 contacts the inner wall of the double-layer shell 218. The product (the inspected product) transported to the inside of the double-layer shell 218 will enter the lower layer of the double-layer shell 218 and then be transported away. When the previously damaged guide shell 106 is repaired or replaced, it can be reset.

[0051] Among them, the guide 104 is composed of components such as a guide rod, a moving rod, a mounting seat and a hand-tightening bolt. When the moving rod moves on the mounting seat, it can drive the guide rod to move. After the moving rod moves to a suitable position inside the mounting seat, the moved moving rod can be fixed by tightening the hand-tightening bolt, thereby fixing the moved guide rod.

[0052] The limiting block 222 is used to prevent the first belt or the second belt from being detached from the first pulley 213 or the second pulley 221 when the first belt or the second belt is in a loose state.
