[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Refer to Figures 1 - 4 , a multi-station detection device for network transformers, including a machine table 10, on which a first detection station 110, a second detection station 120, and a third detection station 130 for placing network transformers 100 are sequentially arranged;

[0024] On the machine table 10 on both the front and rear sides of the first detection station 110, first cameras 210 for detecting the front and rear end face appearances of the network transformer 100 are arranged;

[0025] A pin detection assembly 30 is arranged on the machine table 10, and the pin detection assembly 30 is used to detect the pins of the network transformer 100 in the second detection station 120;

[0026] On the upper and lower sides of the third detection station 130, third cameras 410 are respectively arranged. The third detection station 130 is provided with an opening at the lower end, so that the third camera 410 on the lower side can photograph the network transformer 100 located above through the opening.

[0027] In the actual detection process, the network transformer 100 sequentially enters the first detection station 110, the second detection station 120, and the third detection station 130. First, the front and rear end appearances of the network transformer 100 are detected by the front and rear first cameras 210 to determine whether the front and rear end faces are complete, so as to judge the quality of the product. Then, the network transformer 100 is sent to the second detection station 120. Under the action of the pin detection assembly 30, it can detect whether the left and right rows of pins of the network transformer 100 are complete and whether the left and right end faces of the network transformer are complete. After the detection is completed, the network transformer 100 is transported to the third detection station 130 for detection. The upper and lower third cameras are respectively used to detect the upper and lower end faces of the network transformer 100, and analyze whether the upper and lower end faces are complete to complete the entire detection process.

[0028] Refer to Figure 4 , the pin detection assembly 30 includes a second camera 310 arranged above the second detection station 120; mirrors 320 are respectively arranged on the left and right sides of the second detection station 120. The mirrors 320 are used to project the pins of the network transformer 100 onto the mirror surfaces of the mirrors 320, and the second camera 310 is used to photograph the images of the pins in the mirrors 320.

[0029] Refer to Figure 4, the second detection station 120 includes fixed blocks 121 arranged front and back. The fixed blocks 121 are provided with positioning grooves 122. One side of the positioning groove 122 facing the other positioning groove 122 is open. The front and rear ends of the network transformer 100 are respectively placed in the positioning grooves 122. A hollow area 123 is formed between the front and rear fixed blocks 121. The mirrors 320 are located on the left and right sides of the hollow area 123.

[0030] See Figure 4 , the mirror 320 is inclined upward and gradually away from the hollow area 123. The purpose of the inclined setting is to enable the second camera 310 to better capture the image in the mirror 320.

[0031] Through the application of the left and right mirrors 320, based on the principle of mirror projection, the second camera 310 located above can capture the formation of the left and right rows of pins of the network transformer 100 and the images of the left and right end faces of the network transformer 100. The use of the mirrors 320 can reduce the use of one second camera and effectively reduce the manufacturing cost of the equipment.

[0032] See Figure 3 , the third detection station 130 is a conveying track. A detection window penetrating downward is provided inside the conveying track. The third camera 410 located below can capture the network transformer 100 located above through the detection window; a pushing cylinder 50 for pushing the network transformer 100 to the output end is provided at the input end of the conveying track. The function of the pushing cylinder 50 is that after the detection at the third detection station is completed, the pushing cylinder 50 pushes the network transformer 100 towards the output end of the conveying track to move the network transformer 100 to the next station.

[0033] The third camera 410 located above directly captures the image of the upper end face of the network transformer 100, while the third camera 410 below captures the image of the lower end face of the network transformer 100 through the detection window.

[0034] Based on the above embodiments, the first camera, the second camera, and the third camera are used for image acquisition. The three are connected to an external recognition terminal, and the images are transmitted to the recognition terminal for image recognition and judgment analysis by the recognition terminal.

[0035] See Figure 1 and Figure 2 , the first detection station 110, the second detection station 120, and the third detection station 130 are arranged in sequence from left to right; a moving frame 610 is slidably arranged left and right on the machine table 10. A picking cylinder 620 that moves up and down is arranged on the moving frame 610. A vacuum suction nozzle 630 is installed on the cylinder shaft of the picking cylinder 620.
