Description

Technical Field

[0001] The utility model relates to the technical field of button detection equipment, and more specifically to a positioning detection and rejection device for button detection equipment. Background Art

[0002] As a traditional and commonly used clothing product, buttons come in a variety of styles. Traditional buttons use a punching process to punch multiple holes on the button surface for the button to be installed on clothing. The location, number and size of the holes determine whether the button can be used normally. At the same time, due to the instability of processing, buttons are prone to problems such as button incompleteness, cracks, pores and color difference.

[0003] Therefore, it is necessary to use a button detection device, which is generally a detection device based on visual recognition to detect the position, number and size of the button holes, and whether the buttons are defective, cracked and pore-like. The existing equipment mainly uses a conveyor belt to transport the buttons, but when the buttons are transported on the conveyor belt, the position of the buttons is easily offset, resulting in the camera being unable to fully capture the entire button, affecting the accuracy of visual recognition. At the same time, since the thickness and size of the buttons are not the same, when detecting buttons of different specifications, it is necessary to adjust the position of the sensor and the camera. The adjustment of the existing equipment is not convenient enough and takes a long time. In addition, the existing equipment generally uses a push rod to remove defective buttons, but the running speed of the push rod is limited and the overall efficiency is not high. Based on this, the present application proposes a positioning detection and removal device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] This embodiment discloses a positioning detection and rejection device for a button detection device, such as Figure 1-5 As shown, the machine comprises a frame 1, on which a conveyor belt 2 for conveying buttons is disposed. In this embodiment, two rows of buttons 11 are conveyed on the conveyor belt 2, so two groups of corresponding positioning detection devices 4 and rejection devices 5 are symmetrically disposed. The principles of the two groups of devices are the same, so the following is an explanation of the device of one group:

[0025] The frame 1 of the present embodiment is provided with a positioning detection device 4 and a rejection device 5 arranged front and back along the conveying direction of the conveyor belt 2. The positioning detection device 4 includes a positioning sensor 401. The positioning sensor 401 is provided with a mounting plate 6. The frame 1 is provided with a mounting rod 3 with threads that crosses the conveyor belt 2. The mounting plate 6 is provided with a strip hole 601. The mounting rod 3 passes through the strip hole 601. Nuts A602 and nuts B603 that are threadedly matched with the mounting rod 3 are provided on both sides of the mounting plate 6. The mounting plate is clamped by nuts A and B. Since the thickness and size of buttons are different, it is necessary to adjust the position of the positioning sensor 401 for buttons of different specifications so that the probe thereon can accurately detect the buttons. For details, please refer to Figure 2 A pressing member 7 is provided between the nut A602 and the mounting plate 6, a pressing spring 8 is provided between the nut A602 and the pressing member 7, a rubber layer 701 is provided on the pressing member 7, and the rubber layer 701 is against the mounting plate 6. A rubber ring 10 is provided between the nut B603 and the mounting plate 6. Through the above structure, when adjusting, unscrew the nut A602. At this time, the nut A602 and the nut B603 no longer clamp the mounting plate 6, but due to the presence of the pressure spring 8 and the pressure piece 7, the rubber layer 701 on the pressure piece 7 is still pressed against the mounting plate, and the elastic force of the pressure spring 8 makes the pressure piece 7 and the rubber ring 10 abut against each other, providing friction damping for the adjustment of the mounting plate 6. Then, the staff can adjust the position between the mounting rod 3 and the strip hole 601 with one hand, or rotate the mounting plate 6 for adjustment. After the adjustment is completed, the mounting plate 6 can be fixed by friction damping, and finally the nut A602 can be tightened again to make the nut A602 abut against the pressure piece 7 to complete the fixation. During the process, there is no need to manually support and rotate the nut, which is more convenient to use.

[0026] Furthermore, the rejection device 5 of this embodiment includes an air blowing pipe 501 connected to the electromagnetic valve and a collection bucket 502, and the air blowing pipe 501 is used to blow the defective buttons into the collection bucket 502. Through the above structure, the unqualified buttons are rejected by blowing air, which is more efficient than the prior art that uses a push rod to reject, and helps to improve the overall rejection efficiency.

[0027] For further information, please refer to Figure 1-3The positioning detection device 4 includes a guide plate 402, a fill light component 403 and a camera 404. The guide plate 402 is used to guide the button on the conveyor belt 2 to align with the position of the camera 404. Since the conveyor belt 2 inevitably vibrates during transportation, the position of the button 11 is guided by the guide plate 402 when it is close to the camera 404, wherein the guide plate 402 is preferably set to an arc structure. At the same time, the fill light component 403 is set between the camera 404 and the button, and is used to supplement the light source when the camera 404 is shooting. Due to the complex environment of the production workshop, there may not be a good light source, which affects the clarity of the camera 404 shooting the button and the recognition accuracy. Therefore, the fill light component 403 is set to increase the light source and brightness to ensure clear and accurate shooting and recognition.

[0028] For further information, please refer to Figure 4 The fill light assembly 403 includes a base 4031 with a circular hole, a lens 4032 and a light-emitting element 4033. The lens 4032 is detachably installed in the circular hole of the base 4031. The lens 4032 generally uses a flat lens. In special cases, a magnifying lens can be selected. This is mainly due to the different specifications of buttons. For some particularly small buttons, it is difficult to take clear photos with a camera alone. Therefore, a magnifying lens can be used for physical magnification to assist the camera in taking clear photos. At the same time, in order to ensure good clarity, you can refer to Figure 5 , the light-emitting member 4033 includes a forward light-emitting member 4033A and a side light-emitting member 4033B. The forward light-emitting member 4033A is arranged toward the conveyor belt 2, and the side light-emitting member 4033B is arranged vertically or obliquely with respect to the conveyor belt 2. Through the above-mentioned arrangement, the opening and closing or brightness of the forward light-emitting member 4033A and the side light-emitting member 4033B can be flexibly adjusted for different buttons. For example, for some buttons made of reflective materials, it is necessary to turn off or reduce the brightness of the forward light-emitting member 4033A, and use the side light-emitting member 4033B more to ensure a clear image. For some buttons with complex patterns, it is easy to produce shadows when using the side light-emitting member 4033B, so it is necessary to turn off or reduce the side light-emitting member 4033B, and use the forward light-emitting member 4033A more. In this way, the light source can be flexibly adjusted through the light-emitting members with different irradiation angles to better ensure the clarity of the button image. At the same time, as a preference of this embodiment, the conveyor belt 2 is preferably a black belt body, and black is used as the background color of the buttons, which makes it easier to display the buttons clearly during shooting, thereby ensuring accurate recognition by the visual recognition system.

[0029] For further information, please refer to Figure 3The outlet end of the air blowing pipe 501 of this embodiment is provided with a V-shaped notch 5011, and the notch 5011 is provided on the side close to the conveyor belt 2. By providing the V-shaped notch, when the air from the air blowing pipe is blown out, a part of the air will be discharged from the notch, and this part of the air will move along the surface of the conveyor belt, so that the buttons can be blown up a little, so that the buttons can be blown into the collection bucket 502 better, and the problem of defective buttons not being blown away can be prevented.

[0030] Furthermore, the positioning sensor uses a fiber optic sensor, which is small in size, flexible in installation, and easy to use. It only requires the transmitter to be installed on the mounting plate 6, and then the receiver to be installed at the corresponding position so that the button can pass between the transmitter and the receiver.

[0031] At the same time, a section of optical fiber probe extends from the end of the optical fiber sensor, and this section of optical fiber probe can be closer to the surface of the conveyor belt 2, and is particularly suitable for the detection of flat materials such as buttons.

[0032] Further, see Figure 1 A feeding belt 13 is provided on one side of the conveyor belt 2 for feeding, and a feeding guide plate 131 and an air blowing guide tube 132 are provided between the feeding belt 13 and the conveyor belt 2. The feeding guide plate 131 and the air blowing guide tube 132 are used to guide the buttons on the feeding belt 13 to move toward the conveyor belt 2. The feeding belt 13 is a conveyor belt body for pre-loading, on which there is at least one row of buttons (which can be realized manually or by machine). When the buttons come to the feeding guide plate 131, the air flow blown out by the air blowing guide tube 132 in the same direction as the feeding guide plate 131 is combined, so that the buttons can be smoothly guided to enter the conveyor belt 2 without being blocked, so as to ensure the subsequent normal detection and rejection.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
