DETAILED DESCRIPTION

[0036] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0037] like Figure 1 , 2, 8, a detection device for a chain belt hook code puller, comprising a frame 10, a movable frame 101 is arranged at one end of the frame 10, the movable frame 101 comprises a linear rail 103 movably connected to the frame 10, a slider 104 is formed on the frame 10 and matches the linear rail 103, the frame 10 is provided with a sensing switch 105 for sensing the moving distance of the movable frame 101, a reset member 106 is arranged between the frame 10 and the movable frame 101, the reset member 106 makes the movable frame 101 have a tendency to move closer to the frame 10, the frame 10 and the movable frame 101 have a tendency to move closer to the frame 10, and ... The movable frame 101 is formed with interconnected chain belt feeding tracks 102, on which the chain belt feeding tracks 102 are sequentially provided with a pull head sensing device 20, a defective product discharge device 30 and a clamping device 40, the clamping device 40 being linked and arranged on the movable frame 101, the clamping device 40 comprising a driver 401 and a clamping head 402, the driver 401 driving the clamping head 402 to open or close, the pull head sensing device 20 being used to sense the position of the pull head 501 on the chain belt 50, and the defective product discharge device 30 being used to discharge unqualified pull heads 501 on the chain belt 50;

[0038] When the chain belt feeding track 102 conveys the chain belt 50, the pull head 501 on the chain belt 50 first passes through the pull head sensing device 20. After the pull head sensing device 20 senses the pull head 501, it controls the driver 401 to drive the clamp 402 to close. The pull head 501 is stuck when passing through the clamp 402. The chain belt 50 pulls the pull head 501 to separate the clamping device 40 and the movable frame 101 from the slider 104 of the frame 10. The sensor switch 105 detects the displacement of the movable frame 101, and the pull head 501 is qualified. If the chain belt 50 cannot pull the pull head 501 to separate the clamping device 40 and the movable frame 101 from the slider 104 of the frame 10, and the sensor switch 105 cannot detect the displacement of the movable frame 101, the pull head 501 is unqualified. Specifically, the present invention mainly detects whether the hook code pull head 501 is qualified on the chain belt 50. The chain belt 50 enters the detection device through the chain belt feeding track 102. First, the pull head sensing device 20 senses the position of the hook code pull head 501 on the chain belt 50, and controls the driver 401 to close the clamp 402. When the pull head 501 passes through the clamping device 40, the pull head 501 is against the clamp 402 in the clamping device 40. The qualified pull head 501 is driven by the chain belt 50 to pull the clamping device 40 and the movable frame 101 to separate from the slider 104 of the frame 10, and the frame 10 The induction switch 105 detects the displacement of the movable frame 101, controls the chuck 402 of the clamping device 40 to open, and the pull head 501 passes through the chuck 402. The movable frame 101 moves to the starting position through the reset member 106. The unqualified pull head 501 cannot pull the clamping device and the movable frame 101 to separate from the slider 104 of the frame 10 under the drive of the chain belt 50. The induction switch 105 cannot detect the displacement of the movable frame 101, and the pull head 501 is regarded as a defective product. The defective product discharge device 30 separates the pull head 501 from the blade 502 of the chain belt 50.

[0039] like Figure 4 As shown, when the clamp 402 is in the closed state, a gap 403 is formed in the middle for conveying the chain belt 50. Specifically, the clamp 402 is in the closed state for limiting the movement of the pull head 501, and the gap 403 can be used for normal conveying of the chain belt 50.

[0040] Further, the height of the gap 403 is greater than the height of the chain belt 50 and less than the height of the slider 501. Specifically, the height of the gap 403 cannot be too small or too large, because too small or too large will cause the clamping device 40 to fail to detect the slider 501 normally.

[0041] Furthermore, the driver 401 is a first cylinder 404. Specifically, the clamping device 40 drives the clamp 402 to open or close through the first cylinder 404, so that the clamp 402 can move quickly and be easily installed.

[0042] Furthermore, the pull head sensing device 20 is a visual sensor. Specifically, the pull head 501 on the chain belt 50 is sensed by the visual sensor and the information is transmitted to the clamping device 40.

[0043] Furthermore, the reset member 106 is a spring. Specifically, the spring is connected between the movable frame 101 and the frame 10 to control the movable frame 101 to reset.

[0044] like Figure 1 As shown, the defective discharging device 30 includes a chain belt blade sensing device 301 and a chain splitting device 302. The chain belt blade sensing device 302 senses the position of the blade 502 of the chain belt 50. The chain splitting device 302 is used to open the blade 502 of the chain belt 50. The chain splitting device 302 is arranged on the movable frame 101 at one end close to the frame 10. The chain belt blade sensing device 301 is arranged in front of the chain splitting device 302. Specifically, the unqualified pull head 501 cannot pass through the clamping device 40. The pull head 501 is separated from the blade 502 of the chain belt 50 through the defective discharging device 30. The chain belt blade sensing device 301 is responsible for sensing the position of the blade 502 on the chain belt 50. The chain splitting device 302 opens the blade 502 of the chain belt 50, and the pull head 501 is separated from the chain belt 50 through the clamping device 40.

[0045] like Figure 5 As shown, the chain belt blade sensing device 301 includes a round fishing needle 303 and a sensor 304. The round fishing needle 303 is movably arranged in the middle position of the chain belt feeding track 102, and the top of the round fishing needle 303 is inserted into the chain belt feeding track 102. The sensor 304 senses the displacement change of the round fishing needle 303 and transmits it to the chain splitting device 302 through an electrical signal. Specifically, the round fishing needle 303 is arranged on the chain belt feeding track 102, and the top of the round fishing needle 303 is attached to the chain belt 50. When the blade 502 of the chain belt 50 passes through the round fishing needle 303, the round fishing needle 303 will undergo an angular displacement, which is sent to the chain splitting device 302 through the sensor 304.

[0046] like Figure 3 6, the chain splitting device 302 includes a second cylinder 305 and a minute hand seat 306. The minute hand seat 306 is provided with two minute hands 307. The minute hands 307 are respectively arranged on both sides of the chain belt feeding track 102 on the movable frame 101. The second cylinder 305 controls the minute hand 307 on the minute hand seat 306 to retract or extend. Specifically, the chain splitting device 302 mainly opens the blade 502 of the chain belt 50 and separates the pull head 501 from the chain belt 50. When the blade 502 on the chain belt 50 passes the pull head 501, the second cylinder 305 controls the minute hand 307 on the minute hand seat 306 to extend, open the blade 502, and push the unqualified pull head 501 out of the blade 502 through the clamping device 40.

[0047] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
