Description

Technical Field

[0001] This utility model relates to the field of soft rubber ring feeding technology, specifically, to a soft rubber ring vibratory feeder. Background Technology

[0002] In existing technologies, to improve the sealing performance of temperature sensor housings, rubber rings are typically installed inside the temperature sensor to prevent gas and liquid from entering the sensor and affecting its measurement accuracy and stability. The rubber rings can form an effective seal with the sealing grooves of the sensor housing, preventing gas or liquid from seeping in during use due to gaps between the top cover and the housing, ensuring that the normal operation of the sensor is not affected by the external environment. In addition, the use of rubber rings can also play a buffering role, protecting the internal components of the sensor from mechanical vibration, and improving the durability and reliability of the sensor.

[0003] The process of pressing rubber rings into the temperature sensor housing includes the feeding of rubber rings. Existing technology involves manually placing the rubber rings into the temperature sensor housing, but this method is slow and cannot guarantee the accuracy of placing the rubber rings into the temperature sensor housing. The current mainstream method is to use a robotic arm to clamp the rubber rings into the temperature sensor housing. When feeding, the robotic arm will pick out a rubber ring from the pile. However, when clamping the rubber rings, the robotic arm is prone to picking up multiple rubber rings at the same time. After multiple rubber rings are placed into the temperature sensor housing by the robotic arm, it will cause the rubber rings in the temperature sensor housing to be unable to be pressed in later, which will affect the production speed of the temperature sensor. Utility Model Content

[0004] The purpose of this invention is to provide a vibratory feeder for soft rubber rings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, one of the objectives of this utility model is to provide a vibratory feeding machine for soft rubber rings, including a vibrating device. A bowl-shaped plate is fixedly installed on the top of the vibrating device. A vortex channel is formed on the upper side of the bowl-shaped plate. The vortex channel has a spiral upward funnel-shaped structure. An installation block is fixedly connected to the edge of the top of the bowl-shaped plate. A connecting channel communicating with the vortex channel is formed on the upper side of the installation block. An embedded groove is formed on the installation block. A pneumatic motor is fixedly connected to the installation block. The output shaft of the pneumatic motor extends into the embedded groove and is fixedly connected to a rotating frame. A storage groove is formed on the upper side of the rotating frame. When the rotating frame is completely in the embedded groove, the storage groove and the connecting channel are connected. After the rubber ring enters the storage groove, the pneumatic motor drives the rotating frame to rotate away from the center of the bowl-shaped plate, so that the rubber ring in the storage groove is in a horizontal state.

[0006] As a further improvement to this technical solution, the side of the storage slot away from the connecting channel is provided with an arc shape, and a first sensor is fixedly connected to the bottom inside the storage slot. When the rubber ring enters the inside of the storage slot, the rubber ring fits against the arc-shaped inner wall of the storage slot, and the rubber ring blocks the first sensor, so that the first sensor generates an electrical signal to control the rotation of the pneumatic motor.

[0007] As a further improvement to this technical solution, an electric telescopic rod is fixedly installed on the mounting block. The upper end of the piston rod of the electric telescopic rod extends into the connecting channel. A second sensor is fixedly connected to the bottom of the connecting channel. The second sensor is located between the piston rod of the electric telescopic rod and the rotating frame.

[0008] As a further improvement to this technical solution, the distance between the piston rod of the electric telescopic rod and the rotating frame is the same as the outer diameter of the rubber ring. When the rubber ring moves to the position between the rotating frame and the electric telescopic rod, the rubber ring blocks the second sensor, causing the second sensor to generate an electrical signal to control the electric telescopic rod to extend into the connecting channel. The piston rod of the electric telescopic rod in the connecting channel blocks the rubber ring in the connecting channel.

[0009] As a further improvement to this technical solution, a hemispherical block is fixedly connected to the center of the bottom surface inside the bowl-shaped plate, and the lowest point of the spherical surface of the hemispherical block extends into the interior of the vortex channel.

[0010] As a further improvement to this technical solution, an inner groove is provided on the upper side of the rotating frame, and the inner groove and the storage groove are internally connected.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This soft rubber ring vibrating feeder, after a large number of rubber rings are put into the bowl-shaped plate, the bowl-shaped plate can organize and convey the rubber rings by vibration, so that the rubber rings are arranged and conveyed upward along the spiral channel. When the rubber rings in the spiral channel enter the storage slot, the rotating frame automatically drives the storage slot and the rubber rings in the storage slot to rotate to a horizontal state, which can ensure that there is only one rubber ring in the storage slot, so that the robotic arm gripper can only transfer one rubber ring, thereby ensuring the normal stamping of the rubber rings in the future.

[0013] 2. This soft rubber ring vibrating feeder, when the rotating frame drives the storage trough to rotate upward, intercepts the rubber ring by extending the piston rod of the electric telescopic rod, ensuring that a stationary rubber ring remains between the rotating frame and the electric telescopic rod. After the rotating frame drives the storage trough to rotate and reset, the next rubber ring can quickly enter the storage trough, improving the efficiency of rubber ring replenishment into the storage trough, thereby improving the feeding efficiency of rubber rings.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1-5As shown, one of the objectives of this embodiment is to provide a soft rubber ring vibrating feeder, including a vibrating device 13. A bowl-shaped plate 1 is fixedly installed on the top of the vibrating device 13. Several rubber rings are piled up at the lower part inside the bowl-shaped plate 1. A vortex channel 11 is opened on the upper side of the bowl-shaped plate 1. The vortex channel 11 is a spiral upward funnel-shaped structure. After the vibrating device 13 is started, it drives the bowl-shaped plate 1 to vibrate. The vibrating bowl-shaped plate 1 drives the rubber rings placed on the bowl-shaped plate 1 to vibrate together. The rubber rings that follow the vibration of the bowl-shaped plate 1 will move in the same direction as the vibration of the bowl-shaped plate 1. Some of the moving rubber rings will enter the vortex channel 11. The depth of the vortex channel 11 is only enough to place one rubber ring, so as to ensure that the rubber rings do not overlap in the vortex channel 11. The rubber rings that enter the vortex channel 11 will be neatly arranged inside the vortex channel 11. The rubber rings that enter the vortex channel 11 are spirally conveyed upward along the vortex channel 11 by means of the vibration of the bowl-shaped plate 1.

[0028] Meanwhile, a hemispherical block 12 is fixedly connected to the center of the bottom surface inside the bowl-shaped plate 1. The end of the vortex channel 11 near the center of the bowl-shaped plate 1 is located at the waist of the hemispherical block 12. Some of the rubber rings in the bowl-shaped plate 1 will accumulate on the spherical surface of the hemispherical block 12. When the vibrating device 13 vibrates, the rubber rings on the spherical surface of the hemispherical block 12 will be guided to the lower part of the hemispherical block 12. The rubber rings that move to the lower part of the hemispherical block 12 will enter the bowl-shaped plate 1 and the vortex channel 11 at the lower part of the hemispherical block 12. This makes it easier for the rubber rings to enter the vortex channel 11, so that the rubber rings can continuously move to the upper end of the bowl-shaped plate 1 through the vortex channel 11.

[0029] A mounting block 2 is fixedly connected to the edge of the top of the bowl-shaped plate 1. A connecting channel 21 communicating with the vortex channel 11 is opened on the upper side of the mounting block 2. An embedded groove 22 is opened on the mounting block 2. A pneumatic motor 3 is fixedly connected to the mounting block 2. The output shaft of the pneumatic motor 3 extends into the embedded groove 22 and is fixedly connected to a rotating frame 4. The rotating frame 4 rotates in the embedded groove 22. A storage slot 41 is opened on the upper side of the rotating frame 4. When the rotating frame 4 is completely in the embedded groove 22, the storage slot 41 and the connecting channel 21 are connected. The rubber rings, spiraled upwards by channel 11, enter the storage slot 41 one by one through connecting channel 21. Simultaneously, a first sensor 5 is fixedly connected to the bottom of the storage slot 41. The side of the storage slot 41 away from connecting channel 21 is designed as an arc shape. When the rubber rings enter the storage slot 41, they adhere to the arc-shaped inner wall of the storage slot 41, restricting the position of the rubber rings and causing them to block the first sensor 5. The first sensor 5 is an infrared sensor electrically connected to an external control device. Please refer to [reference needed]. Figure 5When the rubber ring blocks the infrared light emitted by the first sensor 5, the first sensor 5 sends an electrical signal to the control device. The pneumatic motor 3 is electrically connected to the same control device. Upon receiving the electrical signal, the output shaft of the pneumatic motor 3 rotates. The rotating output shaft drives the rotating frame 4 to rotate away from the center of the bowl-shaped plate 1. During the rotation of the rotating frame 4, the rubber ring in the storage slot 41 gradually moves towards the horizontal direction until the storage slot 41 and the rubber ring in the storage slot 41 are rotated to a horizontal state. At this time, the output shaft of the pneumatic motor 3 stops rotating. Then, the rubber ring in the storage slot 41 is removed by the external robotic gripper. In this way, several rubber rings in the bowl-shaped plate 1 are placed horizontally by the rotating frame 4, so that the robotic gripper can only grab one rubber ring at a time, avoiding the situation where the robotic gripper grabs multiple rubber rings at once, and ensuring the normal stamping of the rubber rings in the future.

[0030] To facilitate the robotic gripper's stable gripping of the rubber ring in the storage slot 41, an inner groove 42 is provided on the upper side of the rotating frame 4. The inner groove 42 is connected to the interior of the storage slot 41. When the rubber ring enters the interior of the storage slot 41, a portion of the rubber ring is located directly above the inner groove 42. After the two grippers of the robotic arm move directly above the inner groove 42, the grippers can extend into the inner groove 42. Then, the robotic arm closes the two grippers, so that the two grippers can clamp and fix the rubber ring in a position close to the middle, reducing the possibility of the rubber ring falling off between the two grippers and making it easier for the robotic gripper to remove the rubber ring from the storage slot 41.

[0031] After the robotic gripper removes the rubber ring from the storage slot 41, the infrared radiation emitted by the first sensor 5 is unobstructed. The first sensor 5 will send an electrical signal to the control device, which will control the output shaft of the pneumatic motor 3 to rotate in the opposite direction, rotating the rotating frame 4 and the storage slot 41 to reset, waiting for the next rubber ring to enter the storage slot 41, so as to repeat the rubber ring transfer operation.

[0032] During the rotation of the rotating frame 4, the storage trough 41 and the connecting channel 21 are disconnected. The rubber ring in the connecting channel 21 is blocked by the side wall of the rotating frame 4 and cannot move forward. The rubber rings that cannot move forward in the connecting channel 21 will squeeze each other and fall out of the connecting channel 21. In order to ensure that there are rubber rings in the connecting channel 21 being conveyed to the storage trough 41 after the rotating frame 4 returns to its original position, at least one rubber ring needs to be stored inside the connecting channel 21. This way, after the rotating frame 4 and the storage trough 41 are rotated and reset, one rubber ring in the connecting channel 21 is conveyed to the storage trough 41 by the vibration force of the bowl-shaped plate 1, thereby improving the feeding efficiency of the feeder. To solve this problem, an electric telescopic rod 7 is fixedly installed on the mounting block 2. The upper end of the piston rod of the electric telescopic rod 7 extends into the connecting channel 21. The distance between the piston rod of the electric telescopic rod 7 and the rotating frame 4 is the same as the outer diameter of the rubber ring. A second sensor 6 is fixedly connected to the bottom. The second sensor 6 is located between the piston rod of the electric telescopic rod 7 and the rotating frame 4. When a rubber ring moves to the position between the rotating frame 4 and the electric telescopic rod 7, the rubber ring blocks the second sensor 6. The second sensor 6 is also an infrared sensor, and the second sensor 6 and the electric telescopic rod 7 are electrically connected to the same external control device. When the rubber ring blocks the infrared light emitted by the second sensor 6, the second sensor 6 sends an electrical signal to the control device, causing the control device to control the piston rod of the electric telescopic rod 7 to extend. The extended piston rod extends into the connecting channel 21. The piston rod of the electric telescopic rod 7 in the connecting channel 21 blocks the rubber ring in the connecting channel 21, preventing subsequent rubber rings from entering the position between the rotating frame 4 and the electric telescopic rod 7. This ensures that there is a stationary rubber ring between the rotating frame 4 and the electric telescopic rod 7, improving the efficiency of rubber ring replenishment into the storage slot 41.

[0033] When the rubber ring between the rotating frame 4 and the electric telescopic rod 7 enters the storage slot 41, the infrared light emitted by the second sensor 6 is unobstructed. The second sensor 6 will send an electrical signal to the control device, and the control device will control the piston rod of the electric telescopic rod 7 to shorten to below the connecting channel 21. At this time, the rubber ring inside the vortex channel 11 enters the position between the rotating frame 4 and the electric telescopic rod 7 with the help of the vibration of the bowl-shaped plate 1. The rubber ring that enters the storage slot 41 will block the first sensor 5, causing the rotating frame 4 to drive the rubber ring to rotate to a horizontal position. Repeat the above steps so that the rotating frame 4 continuously conveys a rubber ring for the robot to grip, improving the efficiency of replenishing the rubber ring into the storage slot 41, thereby improving the feeding efficiency of the rubber ring.
