[0028] See also Figure 1As shown, the utility model proposes an automatic material placement mechanism for rubber strips to improve the problem that most of the placement work during the production and processing of perfluoroether rubber products is done manually by workers, the workers have to stand for a long time, the labor intensity is high, the work efficiency is low, and the cleanliness of the rubber strips is affected. Specifically, the automatic rubber strip swinging mechanism includes a tray rotating assembly 10, a rubber strip transmission assembly 20, a length measuring assembly 30, a rubber strip cutting assembly 40, a swinging mechanical arm 50 and a controller. A rubber strip tray 101 is installed on the tray rotating assembly 10, and the rubber strip tray 101 rotates on the tray rotating assembly 10. The rubber strip transmission assembly 20 is connected to the rubber strip 102 and is used to transmit the rubber strip 102. The length measuring assembly is used to measure the length of the rubber strip 102. The rubber strip cutting assembly 40 is used to cut the rubber strip 102 when the rubber strip 102 reaches the set cutting length. The swinging mechanical arm 50 is used to place the cut rubber strip 102 into the corresponding cavity 61 of the mold 60. The controller is electrically connected to the rubber strip transmission assembly 20, the length measuring assembly 30, the rubber strip cutting assembly 40 and the swinging mechanical arm 50, and is used to control the rubber strip transmission assembly 20, the length measuring assembly 30, the rubber strip cutting assembly 40 and the swinging mechanical arm 50.

[0029] See also Figure 1 As shown, in this embodiment, the tray rotating assembly 10 includes a base and a rotating disk. The rotating disk is installed on the base, and the rubber strip tray is installed on the rotating disk. Yes, the rubber strip tray can rotate on the tray rotating assembly 10.

[0030] See also Figure 1 As shown, in embodiment 1, the rubber strip transmission assembly 20 includes a slide, a traction member and a plurality of guide wheels, the traction member is slidably mounted on the slide, and the traction member has a clamping structure for clamping the rubber strip 102, the guide wheel is arranged between the rubber strip cutting assembly 30 and the material tray rotating assembly 10, one end of the rubber strip 102 is led out from the material tray rotating assembly 10, and is connected to the traction machine after passing through the guide wheel, the clamping structure of the traction member clamps one end of the rubber strip 102 and slides along the slide to realize the transmission of the rubber strip, and during the transmission process of the rubber strip 102, the rubber strip material tray rotates on the material tray rotating assembly 10 and gradually releases the rubber strip 102, when the transmitted rubber strip reaches the set length, the controller controls the rubber strip cutting assembly 40 to cut the rubber strip, and controls the swinging robot arm 50 to place the cut rubber strip 102 into the corresponding cavity 61 of the mold 60. It can be understood that a corresponding annular groove can be provided on the guide wheel to adapt to the rubber strip, prevent the rubber strip from falling off, and improve the stability and reliability of the rubber strip transmission.

[0031] See also Figure 1As shown, in this embodiment, the length measurement assembly is a photoelectric encoder or a photoelectric detection device. For example, when the length measurement assembly is a photoelectric encoder, since the guide wheels rotate with the transmission of the rubber strip during the transmission of the rubber strip, the photoelectric encoder is mounted on the rotating shaft of one of the guide wheels. It can be understood that a photoelectric encoder is a sensor that converts the mechanical geometric displacement of the output shaft into pulses or digital quantities through photoelectric conversion. The photoelectric encoder in this application is a ZSP3806-001 series photoelectric encoder 265-24V. It can determine the displacement of the rubber strip based on the displacement of the guide wheel rotation, and then transmit the displacement to the controller. When the displacement reaches a set value, the controller controls the rubber strip cutting assembly 40 to cut the rubber strip, thereby achieving fixed-length cutting of the rubber strip. When the length measurement assembly is a photoelectric detection device, at least one section of the rubber strip transmission path is a straight line. The photoelectric detection device emits an infrared beam toward the rubber strip in this straight section. When the rubber strip passes through the beam, the photoelectric detection device receives the beam signal reflected by the object and determines the object's position and length based on the change in signal intensity.

[0032] See also Figure 1 As shown, in the second embodiment, the rubber strip transmission assembly 20 includes multiple roller assemblies, each of which includes two rollers distributed vertically. The two rollers are clamped on both sides of the rubber strip 102, and the rotation of the rollers drives the rubber strip transmission. In this embodiment, the roller assembly includes a first roller assembly 21, a second roller assembly 22, and a plurality of guide wheels 23. The first roller assembly 21 is located near the material tray rotating assembly 10, and the second roller assembly 22 is located near the rubber strip cutting assembly 40. The guide wheels 23 are located between the first roller assembly 21 and the second roller assembly 22 and serve to guide the transmission to ensure that the rubber strip is transmitted along the correct path. In this embodiment, the rubber strip is transported by the upper and lower rollers clamping the rubber strip and rotating themselves. During the transport of the rubber strip 102, the rubber strip material tray rotates on the material tray rotating assembly 10 and gradually releases the rubber strip 102. When the transported rubber strip reaches a set length, the controller controls the rubber strip cutting assembly 40 to cut the rubber strip and controls the material swinging robot arm 50 to place the cut rubber strip 102 into the corresponding cavity 61 of the mold 60. It can also be understood that an annular groove is provided on the outer circumference of at least one of the two rollers distributed vertically, and the annular groove is adapted to the shape of the rubber strip to better accommodate and transport the rubber strip. Of course, corresponding annular grooves can also be provided on the guide wheels to adapt to the rubber strip, prevent the rubber strip from falling off, and improve the stability and reliability of the rubber strip transport.

[0033] See also Figure 1As shown, in this embodiment, the length measurement component is a photoelectric encoder or a photoelectric detection device. For example, when the length measurement component is a photoelectric encoder, the photoelectric encoder can be mounted on the rotating shaft of the second roller assembly 22. When the length measurement component is a photoelectric detection device, at least one segment of the rubber strip transmission path is a straight line. For example, a third roller assembly is provided, and the third roller assembly 24 and the second roller assembly 22 are located on the same horizontal plane, so that the rubber strip between the third roller assembly 24 and the second roller assembly 22 is a straight line segment. The photoelectric detection device is provided between the third roller assembly 24 and the second roller assembly 22 and emits an infrared beam toward the rubber strip in this straight line segment. When the rubber strip passes through the beam, the photoelectric detection device receives the beam signal reflected by the object and determines the object's position and length based on the change in signal intensity, thereby ensuring the accuracy of the rubber strip length measurement.

[0034] See also Figure 1 As shown, in this embodiment, a plurality of different cavities 61 are provided on the mold 60 so that products of different shapes can be processed and manufactured at the same time, wherein the controller can set the cutting length according to the length of the rubber strip required for the products corresponding to the different cavities. When the length measuring component 20 measures that the length reaches the set length, the controller controls the rubber strip cutting component 40 to cut the rubber strip.

[0035] The utility model proposes an automatic material swinging mechanism for rubber strips, which realizes automatic transmission of rubber strips through a material tray rotating component and a rubber strip transmission component, realizes fixed-length cutting of rubber strips through a length measuring component and a rubber strip cutting component, and automatically places the cut rubber strips of fixed length into the corresponding cavity of the corresponding mold through a material swinging mechanical arm to realize automatic material swinging, replacing manual material swinging operations, improving production efficiency, reducing the probability of dirt, improving product qualification rate, reducing the risk of scalding during manual material swinging, and improving safety precautions.
