Technical Field

[0001] The utility model relates to the technical field of taping machines, and particularly relates to a nozzle positioning mechanism and a taping machine including the same. Background Art

[0002] A taping machine is a device for placing electronic components into a carrier tape. During the working process of the taping machine, first, the electronic components to be woven into the carrier tape are placed on a turntable. When the electronic components move to the target position of the carrier tape, the nozzle of the taping machine presses the electronic components into the carrier tape.

[0003] Therefore, for a taping machine used for extremely small-sized electronic products, the position of the nozzle is crucial. If the adjustment is not good, problems such as wear and breakage will occur. However, other components are arranged on the peripheral side of the nozzle on the taping machine, and the numerical range of the position adjustment of the nozzle is small, making it difficult to directly observe and adjust the position of the nozzle visually. Summary of the Utility Model

[0004] To overcome the above drawbacks, the purpose of the utility model is to provide a nozzle positioning mechanism.

[0005] To achieve the above purpose, the technical solutions adopted by the utility model include:

[0008] A photographing device, capable of taking an image of the surface of the extension portion of the nozzle body close to the tray side, or capable of taking an image of the surface of the electronic component placed on the tray far from the nozzle body side.

[0009] In this application, an opening portion is provided on the tray directly below the extension portion of the nozzle body, and a photographing device is installed below the opening portion of the tray. When positioning the position of the extension portion of the nozzle body, the opening portion of the tray can expose the position of the extension portion of the nozzle body for the photographing device to photograph and record, thereby realizing the positioning of the position of the extension portion of the nozzle body and facilitating the operator to manually adjust the position of the nozzle body.

[0010] In the preferred technical solution of the above nozzle positioning mechanism, the tray is formed with an opening portion penetrating along the telescopic direction of the extension portion.

[0011] By providing the opening portion on the tray, when observing the position of the nozzle body, it will not be blocked by the tray, and the operator's observation and judgment of the nozzle position will not be affected by the limited space below the nozzle body.

[0012] In the preferred technical solution of the above nozzle positioning mechanism, the photographing device at least includes a reflection structure disposed directly below the tray for receiving the image of the bottom of the electronic component or the bottom surface of the extension portion and reflecting the image, and a camera for receiving and photographing the image reflected by the reflection structure.

[0013] In the preferred technical solution of the above nozzle positioning mechanism, when the camera is horizontally configured, the reflection structure is a set of triangular prisms, wherein the camera can receive the image reflected by the triangular prisms.

[0014] In the preferred technical solution of the above nozzle positioning mechanism, when the camera is vertically arranged, the reflection structure is two sets of triangular prisms located at the front end and the rear end respectively, wherein the triangular prism at the front end can reflect the image of the bottom surface of the electronic component or the extension portion of the nozzle body to the triangular prism at the rear end, and the triangular prism at the rear end can receive and reflect the image information reflected by the triangular prism at the front end.

[0015] In the preferred technical solution of the above nozzle positioning mechanism, the tray is formed with guiding portions on both sides of the opening portion for guiding the advancing direction of the electronic component.

[0017] In the preferred technical solution of the above nozzle positioning mechanism, the nozzle positioning mechanism has a lighting device for illuminating the bottom surface of the electronic component and the bottom surface of the extension portion of the nozzle body.

[0018] In the preferred technical solution of the above nozzle positioning mechanism, the light emitted by the lighting device directly irradiates the bottom surfaces of the electronic component and the extension portion of the nozzle body, or the light emitted by the lighting device irradiates the reflection structure and is reflected by the reflection structure to the bottom surfaces of the electronic component and the extension portion of the nozzle body.

[0019] In addition, the present utility model also provides a taping machine, and the taping machine includes the nozzle positioning mechanism of any one of the above embodiments.

[0020] The beneficial effect of the present utility model is that by providing an opening portion directly below the extension portion of the nozzle body on the tray, and installing a triangular prism for reflecting the image and a camera for photographing and recording the reflected image below the opening portion of the tray, when positioning the position of the extension portion of the nozzle body, the opening portion of the tray can expose the position of the extension portion of the nozzle body so as to be reflected by the triangular prism to the camera, and the camera can photograph and record the reflected image, thereby realizing the positioning of the position of the extension portion of the nozzle body, which is convenient for the staff to manually adjust the position of the nozzle body.

Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0033] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] As Figures 1 to 9 shown, the nozzle positioning mechanism of the present utility model includes: a nozzle body 1, having a main body portion 11 and an extension portion 12 extending from the bottom of the main body portion 11 for adsorbing electronic components; a tray 3, located below the nozzle body 1; and a photographing device 2, capable of taking an image of the surface of the extension portion 12 on the side close to the tray 3, or capable of taking an image of the surface of the electronic component placed on the tray 3 on the side away from the nozzle body 1.

[0035] See Figure 1 、 Figure 3 、 Figure 4 , the taping machine has a frame body 41 and a turntable 42 that can rotate intermittently, a guiding structure 43 for limiting the position of the turntable 42, a carrier tape, and a carrier tape conveying device (FEED unit) provided on the frame body 41; wherein, an opening 421 for accommodating electronic components is formed on the outer peripheral side of the turntable 42, and the guiding structure 43 shields the outer peripheral side of the turntable 42, so that when the turntable 42 rotates, the electronic components will not exit the opening 421 on the outer peripheral side of the turntable 42; the device for driving the turntable 42 to rotate intermittently can be a servo motor, or other possible driving sources, such as a rotary cylinder and other driving sources.

[0036] See Figure 2 、 Figure 3 、 Figure 4 , the nozzle body 1 has a main body portion 11 and an extension portion 12, and the extension portion 12 can form adsorption on the electronic components; on the taping machine, the driving device for driving the nozzle body 1 to move up and down can be a driving cylinder, or other possible driving sources.

[0037] See Figure 3, the tray 3 is located at the bottom of the turntable 42 and is directly below the extension 12 of the nozzle body 1; the tray 3 is used to support the carrier tape to facilitate the movement of the carrier tape on the taping machine; after the driving device controls the nozzle body 1 to move downward through the opening 421 on the outer periphery of the turntable 42, the extension 12 of the nozzle body 1 can extend into the carrier tape on the tray 3.

[0038] See Figure 3 , the photographing device 2 is relatively arranged directly below the tray 3 on the taping machine frame 41, and the photographing device 2 can photograph and record the positions of the electronic components supported on the tray 3 and the position of the extension 12 of the nozzle body 1 through the tray 3.

[0039] When detecting the position of the extension 12 of the nozzle body 1, the opening 31 of the turntable 42 does not convey the electronic components, and the opening 31 of the turntable 42 is controlled to be directly above the tray 3 and directly below the extension 12 of the nozzle body 1, so that the position of the extension 12 of the nozzle body 1 can be exposed relative to the tray 3. Thereafter, the photographing device 2 is used to photograph the position of the extension 12 of the nozzle body 1 exposed through the tray 3. When the position of the extension 12 of the nozzle body 1 is deviated, the nozzle body 1 is adjusted according to the position of the extension 12 of the nozzle body 1 in the photographed photo to ensure the adsorption effect of the nozzle body 1 on the electronic components.

[0040] After the position adjustment of the extension 12 of the nozzle body 1 is completed, the electronic components can be woven into the carrier tape. The specific process includes: putting the electronic components into the opening 421 of the turntable 42, conveying the carrier tape to the tray 3, controlling the turntable 42 to rotate through the servo motor so that the electronic components are directly above the carrier tape on the tray 3 and directly below the extension 12 of the nozzle body 1. Thereafter, the driving device is used to control the nozzle body 1 to move downward so that the extension 12 of the nozzle body 1 abuts against and adsorbs the electronic components, and the driving device is continuously used to drive the extension 12 of the nozzle body 1 to move downward to the tray 3. After the electronic components are inserted into the carrier tape placed on the tray 3, the nozzle body 1 is controlled to reset, and the turntable 42 is rotated again so that the electronic components are directly above the tray 3 and directly below the extension 12 of the nozzle body 1. At the same time, the carrier tape is controlled to move so that the part of the carrier tape without woven electronic components is directly below the electronic components. Thereafter, the above operations are repeated.

[0041] In one or more embodiments, the tray 3 is formed with an opening 31 penetrating along the telescopic direction of the extension 12; the size of the opening 31 is configured to be able to accommodate at least the extension 12 of the nozzle body 1; the tray 3 is formed with guiding parts 32 on both sides of the opening 31 for guiding the advancing direction of the electronic components.

[0042] See Figure 5, an opening 31 vertically penetrating is formed on the tray 3. The opening 31 on the tray 3 is located directly below the extension 12 of the nozzle body 1. The photographing device 2 can obtain the image information of the bottom surface of the extension 12 of the nozzle body 1 through the opening 31. Or, when the turntable 42 drives the electronic component to directly above the opening 31 of the tray 3, the electronic component at least partially blocks the opening 31 of the tray 3, that is, the electronic component blocks the extension 12 of the nozzle body 1. At this time, the photographing device 2 can only obtain the image information of the bottom surface of the electronic component.

[0043] See Figures 2 to 5 , when the opening 31 of the tray 3 is large enough, the photographing device 2 can obtain the image information of the turntable 42, the guiding structure 43 and the nozzle body 1 through the opening 31 of the tray 3; the size of the opening 31 of the tray 3 is selected according to actual needs, and there is no specific limitation.

[0044] See Figure 4 , along the conveying direction of the carrier tape, guiding parts 32 are formed upward on both sides of the top surface of the tray 3 at the opening 31. When the carrier tape is conveyed, the carrier tape will be restricted by the guiding parts 32 to reduce the generation of displacement, ensuring the efficiency of the electronic components being woven into the carrier tape.

[0045] In one or more embodiments, the photographing device 2 at least includes a reflecting structure 21 disposed directly below the tray 3 for receiving the bottom image of the electronic component or the bottom surface of the extension 12 and reflecting the image, and a camera 22 for receiving and photographing the image reflected by the reflecting structure 21.

[0046] See Figure 2 , the reflecting structure 21 is a triangular prism for reflection, and the camera 22 can photograph and record the image reflected by the triangular prism. Among them, the position of the camera 22 has two placement methods:

[0047] See Figure 2 、 Figure 7 , when the camera 22 is placed horizontally, there is a group of triangular prisms. The triangular prism is located directly below the opening 31 of the tray 3. The triangular prism can vertically reflect the image information of the bottom surface of the extension 12 of the nozzle body 1 exposed through the opening 31 of the tray 3. The camera 22 is arranged on the path of the reflected image information of the triangular prism. The camera 22 can realize the positioning of the position information of the bottom surface of the extension 12 of the nozzle body 1 by photographing and recording the reflected image information; by adjusting the direction of the reflected image information of the triangular prism, the replacement of the position of the camera 22 can be realized. Therefore, the position of the camera 22 when placed horizontally is not limited.

[0048] See Figure 8 、 Figure 9, when the camera 22 is placed vertically, there are two sets of prisms, namely the prism configured at the front end and the prism configured at the rear end. The prism at the front end can reflect the image information of the bottom surface of the extension part 12 of the nozzle body 1 towards the prism at the rear end, and the vertically placed camera 22 can take pictures and record the image information reflected by the prism at the rear end, so as to realize the positioning of the extension part 12 of the nozzle body 1, facilitating the staff to adjust the position of the nozzle body 1; by adjusting the rotation directions of the prism at the front end and the prism at the rear end, the replacement of the position of the camera 22 can be realized. Therefore, there is no limit to the position of the camera 22 when it is placed vertically.

[0049] In this application, according to the different placement positions of the camera 22, the corresponding number of prisms are configured so that the camera 22 can take pictures and record the position information of the extension part 12 of the nozzle body 1. Through this setting, the diversity of the installation position of the camera 22 can be guaranteed, the problem of interference between the camera 22 and other components of the taping machine can be reduced, and the use effect of this application can be improved.

[0050] In other possible implementation manners, the camera 22 is located directly below the opening 31 of the tray 3; through this setting, the camera 22 can directly take pictures and record the extension part 12 of the nozzle body 1 through the opening 31 of the tray 3, reducing the use of components.

[0051] In one or more embodiments, the nozzle positioning mechanism has an illumination device for illuminating the bottom surface of the electronic component and the bottom surface of the extension part 12 of the nozzle body 1; the light emitted by the illumination device directly irradiates the bottom surfaces of the electronic component and the extension part 12 of the nozzle body 1, or the light emitted by the illumination device irradiates to the reflection structure 21 and is reflected by the reflection structure 21 to the bottom surfaces of the electronic component and the extension part 12 of the nozzle body 1.

[0052] The position of the illumination device is not shown in the drawings. The illumination device can be an LED lamp; the illumination device can be configured on the taping machine frame 41 to face the opening 31 of the tray 3 and the extension part 12 of the nozzle body 1 from bottom to top, or irradiate on the prism, and the prism reflects the light so that the light passes through the opening 31 of the tray 3 and illuminates the bottom surface of the extension part 12 of the nozzle body 1 upward; the specific position of the illumination device is not limited. In addition, it should be noted that the number of the illumination devices can be one or more, as long as it can illuminate the electronic component and the predetermined position of the nozzle body 1.

[0053] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
