Therefore, the directions and positions used are for explaining and understanding the present invention, but not for limiting the scope of protection of the present invention.

[0021] like Figures 1 to 7 As shown, an embodiment of the present invention is an online visual recognition and automatic rejection mechanism for zipper heads, which is used to detect and screen zipper heads 1, and includes a transmission device, a visual recognition device 2, and a rejection device 3. The transmission device includes a vibration plate 4 and a guide rail assembly. The guide rail assembly includes an upper guard plate 5 and a lower guard plate 6. The end surface of the lower guard plate 6 facing the upper guard plate 5 is protruded with a support sheet 7. A transmission channel 8 for transmitting the zipper head 1 is formed between the upper guard plate 5 and the lower guard plate 6. The vibration plate 4 transmits the zipper head 1 toward the transmission channel 8. The visual recognition device 3 is used to detect and screen zipper heads 1. 2 is used to identify whether the zipper head 1 in the transmission channel 8 is qualified. The lower guard plate 6 is provided with a first groove 9 connected with the transmission channel 8. The rejection device 3 reciprocates along the first groove 9. The position of the upper guard plate 5 corresponding to the first groove 9 is provided with a notch 10 for the zipper head 1 to pass through. When the visual recognition device 2 recognizes that the zipper head 1 is unqualified, the rejection device 3 moves along the first groove 9 to push the zipper head 1 out of the notch 10. When the visual recognition device 2 recognizes that the zipper head 1 is qualified, the zipper head 1 continues to be transmitted along the transmission channel 8.

[0022] The beneficial effects of such an arrangement are as follows: the mechanism of the present invention enables the zipper head to be automatically transmitted along the transmission channel through the transmission device, and the zipper head is identified online to see whether it is qualified through the visual recognition device; when an unqualified zipper head is identified, the zipper head is automatically rejected through the rejection device, that is, the quality inspection in the form of an automated assembly line replaces the traditional manual quality inspection, with a low error rate and improved production quality and efficiency.

[0023] It is further configured that the visual recognition device 2 includes a support frame 11 and an industrial camera 12 , wherein the industrial camera 12 is slidably connected to the support frame 11 via a slide rail sleeve 13 , and the industrial camera 12 is used to capture images of the zipper head 1 in the transmission channel 8 .

[0024] The beneficial effects of this setting are as follows: the industrial camera is slidably connected to the support frame through the slide rail sleeve, which facilitates the adjustment of the angle and position of image acquisition, improves the quality of image acquisition, and ensures the accuracy of quality inspection results. The industrial camera uses a CMOD camera with automatic or manual adjustment of gain, exposure time, white balance, LUT, Gamma correction and other functions. It also uses VisionMaster 4.2.0 visual recognition design software, which can accurately identify zipper heads and accurately screen them.

[0025] It is further configured that the visual recognition device 2 also includes an annular light source 14 and a connecting column 15, one end of the connecting column 15 is connected to the end of the support frame 11 and the other end is provided with a connecting block 16, the annular light source 14 is abutted against the end of the support frame 11 through the connecting column 15 and the connecting block 16, and the annular light source 14 surrounds the industrial camera 12.

[0026] The beneficial effects of this arrangement are as follows: the annular light source provides good lighting conditions for the industrial camera, allowing the zipper head to be detected more clearly and quickly. The annular light source is also installed at the end of the support frame through connecting columns and connecting blocks for easy disassembly and assembly.

[0027] It is further configured that the rejection device 3 includes a first push rod 17 and a first electromagnet 18, and the first electromagnet 18 drives the first push rod 17 to move back and forth along the first groove 9. When the visual recognition device 2 recognizes that the zipper head 1 is unqualified, the first electromagnet 18 drives the first push rod 17 to move toward the notch 10 to push the zipper head 1 out of the notch 10.

[0028] The beneficial effects of such a configuration are as follows: the rejection device is a structure in which an electromagnet drives a push rod to extend and retract. When the zipper head is identified as unqualified by the visual recognition device, the first push rod extends along the first groove to push the unqualified zipper head from the transmission channel along the notch to the outside, thereby realizing a screening function. The first push rod also has a U-shaped structure, and the two ends of the U-shaped top abut against the two sides of the zipper head at the same time when pushed, so that the unqualified zipper head can be pushed out smoothly.

[0029] The invention is further configured to include an auxiliary device, which is located at a side position above the notch 10. The auxiliary device includes a second push rod 19 and a second electromagnet 20. The second electromagnet 20 drives the second push rod 19 to reciprocate in a direction perpendicular to the center line of the notch 10. When the zipper head 1 is pushed out of the notch 10 by the removal device 3, the second electromagnet 20 drives the second push rod 19 to move in the direction of the center line of the notch 10 to push the zipper head 1 from above the notch 10 to one side.

[0030] The beneficial effects of such a configuration are as follows: the auxiliary device is also a structure in which an electromagnet drives the push rod to extend and retract, but the auxiliary device is located on the side above the notch. When the rejection device pushes the unqualified zipper head above the notch, the auxiliary device performs a secondary rejection to completely push the zipper head away from the notch to prevent the zipper head from having a certain contact with the notch or being stuck in the notch, thereby ensuring the stability of the rejection process.

[0031] It is further configured that a small guard plate 21 is provided on the side of the upper guard plate 5 corresponding to the notch 10 and away from the auxiliary device. The small guard plate 21 is inclined toward the lower guard plate 6. An end of the small guard plate 21 close to the notch 10 is provided with a make way groove 22 for the first push rod 17 to pass through.

[0032] The beneficial effects of such a configuration are as follows: a small guard plate is installed on the side of the upper guard plate corresponding to the other side of the auxiliary device. The small guard plate is used to allow unqualified zipper heads to slide down after being rejected for the second time by the auxiliary device. It can guide the movement direction of the rejected unqualified zipper heads and facilitate the collection of unqualified zipper heads. The yield groove of the small guard plate allows the first push rod of the rejection device to give way, ensuring that the first push rod can completely push the unqualified zipper head to the outside of the notch.

[0033] It is further provided that a guide piece 23 is respectively provided on the inner wall positions on both sides of the upper guard plate 5 corresponding to the notch 10 , and the two guide pieces 23 are respectively used for guiding the two sides of the zipper head 1 .

[0034] The beneficial effect of such a configuration is as follows: the guide pieces on the inner walls on both sides of the notch can cooperate with the gap through which the zipper passes when the zipper head is in use, further guiding the moving direction of the unqualified zipper head and helping the unqualified zipper head to be smoothly removed.

[0035] Further configuration includes a guide block 24, the vibration plate 4 is provided with a discharge port 25 for transmitting the zipper head 1, one end of the guide block 24 is connected to the guide rail assembly and the other end is connected to the discharge port 25, the guide block 24 is provided with a guide groove 26 for the zipper head 1 to pass through, and the zipper head 1 moves from the discharge port 25 along the guide groove 26 to the transmission channel 8.

[0036] The beneficial effects of this arrangement are as follows: the discharge port of the vibration plate and the transmission channel of the guide rail assembly are connected by the guide block, guiding the zipper head to smoothly enter the transmission channel from the discharge port, thereby preventing the discharge port from being misaligned with the transmission channel and the zipper head from being unable to enter the transmission channel.

[0037] The invention is further provided with at least two first bolt members 27 and at least one second bolt member 28. The guide block 24 is fixedly connected to the upper guard plate 5 and the lower guard plate 6 by a first bolt member 27 respectively. The inner wall of the discharge port 25 is recessed with a mounting groove 29 for installing the guide block 24. A through hole 30 connected to the mounting groove 29 is formed on the side of the discharge port 25. The second bolt member 28 passes through the through hole 30 and is threadedly connected to the guide block 24. The second bolt member 28 limits the guide block 24 in the mounting groove 29. The guide block 24 slides back and forth in the mounting groove 29 along the axis direction of the second bolt member 28.

[0038] The beneficial effects of such a configuration are as follows: in the present embodiment, the first bolt member and the second bolt member are both screws, and the guide block is fixedly connected to the upper guard plate and the lower guard plate at the same time by a first bolt member respectively. The guide block is firmly connected and the size of the transmission channel is limited to prevent the upper guard plate and the lower guard plate from sliding relative to each other, causing the transmission channel to become larger or smaller, resulting in the zipper head being unable to be transmitted. The guide block is connected to the discharge port by a second bolt member, and a movable connection is adopted, that is, the guide block can move in the mounting groove of the discharge port along the direction of the axis of the second bolt member. The purpose of this structure is to offset the vibration generated when the vibration disk is working, the deviation of the guide block and the discharge port, and the influence on the zipper head being unable to enter the guide groove of the guide block.

[0039] Further configuration includes an elastic member 31 , one end of the elastic member 31 abuts against the inner wall of the installation groove 29 and the other end abuts against the outer wall of the guide block 24 . A boss 32 protrudes from the inner wall of the installation groove 29 , and the elastic member 31 is sleeved around the boss 32 .

[0040] The beneficial effects of this arrangement are as follows: the position compensation of the guide block and the mounting slot is provided by the elastic member. In this embodiment, the elastic member is a spring, which further reduces the influence of vibration of the vibration plate so that the guide block is aligned with the discharge port, and the boss is used to prevent the spring from torsional failure.

[0041] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
