[0027] During specific use, through the arrangement of the bidirectional screw 3, the first slider 4, the fixed seat 5, the second motor 6, the driving wheel 7 and the driven wheel 11, the first motor 2 drives the bidirectional screw 3 to rotate, so that the two first sliders 4 on the outer surface are close to or separated from each other, and the spacing between the two fixed seats 5 is adjusted according to the size of the workpiece, which is suitable for the detection of workpieces of different sizes, thereby expanding the use range of the device, and enhancing the applicability and flexibility. The second motor 6 drives the driving wheel 7 to rotate, and the synchronous belt 9 is transmission-connected to the outer surfaces of the first synchronous wheel 8 and the second synchronous wheel 10, and performs circular reciprocating motion under the action of the driving wheel 7, so that multiple driven wheels 11 can rotate synchronously with the driving wheel 7, and the workpiece can be continuously conveyed, thereby ensuring the stability of the workpiece conveying and improving the detection efficiency. The driving wheel 7 and the driven wheel 11 can be made of rubber material, and the friction coefficient of rubber is relatively high, which can effectively improve the interaction force between the workpiece and the conveying mechanism, avoid slipping during contact and affect the effect of conveying detection, and enhance the work efficiency.

[0028] In this embodiment, a fixing rod 12 is fixedly connected to the inner top wall of the fixing seat 5 , and a roller 13 is rotatably connected to the outer surface of the fixing rod 12 .

[0029] During specific use, by setting the roller 13, the roller 13 is rotatably connected to the outer surface of the fixed rod 12, and the two sides of the workpiece are limitedly conveyed, so as to further improve the stability of the side conveying of the workpiece and improve the conveying efficiency.

[0030] In this embodiment, both sides of the inner side of the base 1 are fixedly connected with guide rods 14 , both sides of the outer surface of the guide rod 14 are slidably connected with second sliders 15 , and the second sliders 15 are fixedly connected to the fixing seat 5 .

[0031] During specific use, through the setting of the guide rod 14, when the fixed seat 5 moves, the second slider 15 on its lower surface moves along with the guide rod 14, thereby increasing the supporting effect on the fixed seat 5, so that it can only move horizontally on the outer surface of the guide rod 14, so that the two ends of the fixed seat 5 maintain the balance and stability of movement.

[0032] In this embodiment, a guide groove 16 is formed on one side of the upper surface of the base 1 close to the first sliding block 4 and the second sliding block 15 .

[0033] During specific use, the guide groove 16 is provided to facilitate the movement of the first slider 4 and the second slider 15 and further guide the two.

[0034] In this embodiment, brackets 17 are fixedly connected to both sides of the upper surface of the base 1 , and a display screen 18 is fixedly connected to the front of the bracket 17 .

[0035] During specific use, through the setting of the display screen 18, the bracket 17 is used to support the detection element of the fixing device, and the display screen 18 can display the detection picture and data for the convenience of the staff to watch.

[0036] In this embodiment, a hydraulic rod 19 is fixedly connected to the upper surface of the bracket 17 , and a connecting plate 20 is fixedly connected to the lower surface of the hydraulic rod 19 .

[0037] During specific use, by setting the hydraulic rod 19, the output end of the hydraulic rod 19 is extended and retracted, so that the height of the first detection head 21 can be adjusted, and the adjustable range is enhanced.

[0038] In this embodiment, a first detection head 21 is fixedly connected to one side of the lower surface of the connecting plate 20 , and a second detection head 22 is fixedly connected to the middle of the upper surface of the base 1 .

[0039] During specific use, by setting the first detection head 21 and the second detection head 22, the two can detect the upper surface and the lower surface of the workpiece at the same time, which expands the detection range, speeds up the detection efficiency, and can meet various usage requirements.

[0040] In this embodiment, an infrared transmitter 23 is fixedly connected to the other side of the lower surface of the connecting plate 20 , and an infrared receiver 24 is fixedly connected to the middle of the upper surface of the base 1 .

[0041] When used specifically, the infrared transmitter 23 and the infrared receiver 24 are set up to transmit and receive infrared rays respectively, so as to sense the workpiece and judge whether the workpiece stays at the designated location for detection, thereby improving the automation degree of the device.

[0042] Working principle: During use, the first motor 2 drives the bidirectional screw 3 to rotate, so that the two first sliders 4 are brought closer to or separated from each other, and the spacing between the two fixed seats 5 is adjusted according to the size of the workpiece. The second motor 6 drives the driving wheel 7 to rotate, and the synchronous belt 9 is connected to the outer surface of the first synchronous wheel 8 and the second synchronous wheel 10, so that multiple driven wheels 11 can rotate synchronously with the driving wheel 7 to continuously convey the workpiece. The roller 13 limits the conveying of both sides of the workpiece. The infrared transmitter 23 and the infrared receiver 24 are used to transmit and receive infrared rays respectively. When the workpiece is conveyed to the middle of the two, the infrared receiver 24 cannot receive infrared rays, thereby stopping the conveying of the workpiece. The output end of the hydraulic rod 19 is retracted to adjust the height of the first detection head 21. The upper and lower surfaces of the workpiece are detected simultaneously by the first detection head 21 and the second detection head 22, thereby speeding up the detection efficiency. The display screen 18 can display the detected images and data for easy viewing by the staff.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
