Description

Technical Field

[0001] This utility model relates to the field of temperature sensor manufacturing technology, and more specifically, to a rubber ring uniform packing device. 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 feeding the rubber rings. In the prior art, a vibrating feeder 2 is usually used to arrange several rubber rings neatly and then transport the neatly arranged rubber rings one by one to a position that can be reached by the gripper of the robotic arm. When the number of rubber rings in the vibrating feeder 2 decreases to a predetermined number, the rubber rings need to be manually placed onto the vibrating feeder 2. However, although the vibrating feeder 2 will disperse some of the rubber rings by vibration, most of the rubber rings will still not be dispersed by vibration. The rubber rings that cannot be dispersed will affect the normal conveying of rubber rings by the vibrating feeder 2. When the vibrating feeder 2 cannot convey rubber rings, it will affect the production of the entire process and thus affect the production speed of the sensor housing. Utility Model Content

[0004] The purpose of this invention is to provide a rubber ring uniform filling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, one objective of this utility model is to provide a rubber ring uniform filling device, including a housing with an opening on one side. A conveyor belt for conveying rubber rings is installed inside the housing, with one end of the conveyor belt passing through the opening and extending to the outside of the housing. A vibrating feeding plate is positioned below the housing. Two moving blocks are symmetrically arranged on the upper side of the conveyor belt near the opening. Several rakes are horizontally arrayed and fixedly connected to the bottom of each moving block. A gap is provided between the lower end of each rake and the upper side of the conveyor belt. A displacement mechanism is installed inside the housing near the opening, positioned on the upper side of the conveyor belt. The displacement mechanism is used to drive two moving blocks to move relative to each other. Two rotating plates are symmetrically connected to the lower end of the box near the opening. Gears are fixedly connected to the rotating plates and the box at the rotatable connection position. The two gears mesh with each other. A guide plate is fixedly connected to the side of the rotating plate away from the box. A space is left between the two guide plates for the rubber ring to fall. A support rod is provided on the lower side of one of the guide plates. A reciprocating mechanism is provided on the support rod. When the displacement mechanism drives the two moving blocks to move relative to each other, the displacement mechanism drives the reciprocating mechanism to move the support rod up and down. The moving support rod causes the guide plate to swing up and down on one side of the box.

[0006] As a further improvement to this technical solution, the displacement mechanism includes a rotating rod rotatably disposed inside the housing. Two threaded grooves with opposite directions are symmetrically opened near both ends of the rotating rod. The two moving blocks are respectively threadedly connected to the two threaded grooves. A second motor for driving the rotating rod to rotate is provided at one end of the rotating rod. The second motor is fixedly installed on the housing. A sliding rod is fixedly disposed inside the housing. Both moving blocks are slidably sleeved on the sliding rod.

[0007] As a further improvement to this technical solution, the reciprocating mechanism includes a connecting plate fixedly connected to one end of the support rod, a guide sleeve slidably sleeved on the connecting plate, the guide sleeve being fixedly disposed on one side of the housing, a sleeve frame being fixedly connected to the end of the connecting plate away from the support rod, and an eccentric wheel being fixedly connected to the end of the rotating rod away from the second motor through the side wall of the housing, the eccentric wheel being disposed inside the sleeve frame.

[0008] As a further improvement to this technical solution, a vertical pole is provided on one side of the box body, a clamp is provided on the side wall of the vertical pole, an extension frame is fixedly connected to one side of the clamp, a strip is rotatably connected to one side of the extension frame, a gap is provided between the lower end of the strip and the upper side of the vibrating feeding plate, and an infrared sensor is fixedly connected to the extension frame. When the strip is perpendicular to the ground, the strip blocks the infrared rays emitted by the infrared sensor.

[0009] As a further improvement to this technical solution, two belt rollers are rotatably arranged inside the box near the bottom, and the conveyor belt is connected to the two belt rollers. A first motor is fixedly installed on one side of the box, and the output shaft of the first motor is coaxially and fixedly connected to one of the belt rollers.

[0010] As a further improvement to this technical solution, an ion fan is fixedly installed on the top of the box, and the ion fan is used to blow an airflow containing ions onto the vibrating feeding plate.

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

[0012] 1. This rubber ring uniform filling device has a horizontally movable rake on the upper side of the conveyor belt. Before the rubber ring is conveyed to the vibrating feeding plate, the rake flattens the rubber ring on the conveyor belt. At the same time, two guide plates are symmetrically rotated on one side of the box. When the rubber ring falls from the conveyor belt, the swinging guide plates adjust the landing point of the rubber ring on the vibrating feeding plate, so that the rubber ring in the vibrating feeding plate is evenly distributed, improving the efficiency of the vibrating feeding plate in sorting and conveying rubber rings.

[0013] 2. In this rubber ring uniform filling device, when there is a lack of rubber rings in the vibrating feeding plate, the strip plate is in a vertical position to the ground due to the lack of rubber rings. At this time, the strip plate blocks the infrared rays emitted by the infrared sensor. The infrared sensor sends an electrical signal to the control equipment, which starts the first motor, so that the conveyor belt can fill the vibrating feeding plate with rubber rings in time, avoiding the depletion of rubber rings in the vibrating feeding plate and preventing workers from forgetting to feed the vibrating feeding plate, thus ensuring the normal feeding of rubber rings by the vibrating feeding plate.

[0028] 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.

[0029] Example 1

[0030] Please see Figures 1-4 As shown, one of the objectives of this embodiment is to provide a rubber ring uniform filling device, including a housing 1 with an opening on one side. A conveyor belt 32 for conveying rubber rings is installed inside the housing 1. Multiple rubber rings are stacked on the upper surface of the conveyor belt 32. One end of the conveyor belt 32 passes through the opening and extends to the outside of the housing 1. A vibrating feeding plate 2 is located below the housing 1. Two belt rollers 3 are rotatably arranged near the bottom inside the housing 1. The conveyor belt 32 is driven and connected to the two belt rollers 3. A first motor 31 is fixedly installed on one side of the housing 1. The first motor 31 is a low-speed motor. The output shaft of the first motor 31 is coaxially and fixedly connected to one of the belt rollers 3. After the first motor 31 starts, its output shaft drives one of the belt rollers 3 to rotate slowly. The belt roller 3 drives the conveyor belt 32 to rotate, and the conveyor belt 32 slowly conveys several rubber rings towards the opening. When the rubber rings fall from the conveyor belt 32, they land on the upper side of the vibrating feeding plate 2, thus filling the vibrating feeding plate 2 with rubber rings.

[0031] Meanwhile, a vertical pole 4 is installed on one side of the housing 1, and a clamp 41 is installed on the side wall of the vertical pole 4. An extension frame 42 is fixedly connected to one side of the clamp 41, and a strip 44 is rotatably connected to one side of the extension frame 42. A gap is provided between the lower end of the strip 44 and the upper side of the vibrating feeding plate 2. An infrared sensor 43 is fixedly connected to the extension frame 42. The infrared sensor 43 and the first motor 31 are both electrically connected to an external control device. When the vibrating feeding plate 2 vibrates and conveys the rubber ring, the moving rubber ring will push the lower end of the strip 44, causing the lower end of the pushing strip 44 to be pushed and rotated. After rotation, the strip 44 will not block the infrared sensor. When the infrared light emitted by the external sensor 43 is low, the infrared sensor 43 sends an electrical signal to the control device, causing the control device to shut down the first motor 31. When there are few rubber rings in the vibrating feed plate 2, and there are no rubber rings on the vibrating feed plate 2, the lower side of the pushing strip 44 will be kept perpendicular to the ground under the action of gravity. At this time, the strip 44 blocks the infrared light emitted by the infrared sensor 43. The infrared sensor 43 sends an electrical signal to the control device, causing the control device to start the first motor 31, so that the conveyor belt 32 conveys rubber rings to the vibrating feed plate 2, thus preventing the rubber rings in the vibrating feed plate 2 from being exhausted.

[0032] When the vibrating feeding plate 2 vibrates and conveys the rubber ring, friction occurs between the rubber ring and the vibrating feeding plate 2, causing the rubber ring to become statically charged. There is an attraction force between the statically charged rubber ring and the vibrating feeding plate 2, which reduces the sorting and conveying efficiency of the rubber ring by the vibrating feeding plate 2. To solve this problem, an ion fan 11 is fixedly installed on the top of the housing 1. The ion fan 11 is used to blow an airflow carrying ions onto the vibrating feeding plate 2. When the positively and negatively charged airflow blown out by the ion fan 11 comes into contact with the rubber ring, it can effectively neutralize the charge on the surface of the rubber ring, thereby eliminating the static electricity on the rubber ring and ensuring the sorting and conveying efficiency of the rubber ring by the vibrating feeding plate 2.

[0033] When the conveyor belt 32 transports the rubber rings to the vibrating feeding plate 2, if the rubber rings on the conveyor belt 32 are unevenly distributed, the rubber rings falling onto the vibrating feeding plate 2 will also be unevenly distributed, causing inconvenience to the rubber ring sorting and conveying work of the vibrating feeding plate 2. To solve this problem, two moving blocks 5 are symmetrically arranged on the upper side of the conveyor belt 32 near the opening. Several rake rods 51 are fixedly connected to the bottom of the moving blocks 5 in a horizontal array. A gap is provided between the lower end of the rake rods 51 and the upper side of the conveyor belt 32. This gap is greater than one but less than the height of two rubber rings placed on the horizontal plane, so as to ensure that the rake rods 51 can evenly move the rubber rings. A displacement device is provided inside the housing 1 near the opening. Mechanism 7, the displacement mechanism 7 is set on the upper side of the conveyor belt 32. The displacement mechanism 7 is used to drive two moving blocks 5 to move relative to each other. When a part of the rubber ring on the conveyor belt 32 is about to fall into the vibrating feed plate 2, the two moving blocks 5 are located above the part of the rubber ring. At this time, the two moving blocks 5 are made to move relative to each other. The moving blocks 5 drive several rakes 51 to move synchronously. The moving rakes 51 flatten the rubber rings that are piled up higher, so that the rubber rings that have been in contact with the rakes 51 on the conveyor belt 32 are more evenly distributed. After the flattened rubber rings fall into the vibrating feed plate 2, the spiral vibration conveying of the rubber rings by the vibrating feed plate 2 makes the distribution of this part of the rubber rings on the vibrating feed plate 2 more even.

[0034] The structure of displacement mechanism 7 is detailed below, referring to... Figure 4 The displacement mechanism 7 includes a rotating rod 71 rotatably disposed inside the housing 1. Two oppositely oriented threaded grooves 72 are symmetrically formed near both ends of the rotating rod 71. Two rotating plates 8 are threadedly connected to the two threaded grooves 72 respectively. A second motor 73 for driving the rotating rod 71 to rotate is disposed at one end of the rotating rod 71. The second motor 73 is fixedly mounted on the housing 1. A sliding rod 74 is fixedly disposed inside the housing 1. The axes of the sliding rod 74 and the rotating rod 71 are parallel to each other. Two moving blocks 5 are slidably sleeved on the sliding rod 74. After the second motor 73 is started, its output shaft drives the rotating rod 71 to rotate. The movable block 5 is connected to the threaded groove 72 by the threaded connection, so that the movable block 5 can move horizontally along the axis of the slide rod 74. Since the thread directions of the two threaded grooves 72 are opposite, the moving directions of the two movable blocks 5 are also opposite. The second motor 73 is a servo motor with a variable output shaft rotation direction. When the movable block 5 moves to one end of the threaded groove 72, the second motor 73 changes the rotation direction of the output shaft, so that the movable block 5 moves closer to the other end of the threaded groove 72. In this way, the movable block 5 moves back and forth on the corresponding threaded groove 72, so that the movable block 5 can continuously flatten the rubber ring by the rake rod 51.

[0035] To ensure a more even distribution of rubber rings on the vibrating feed plate 2, two rotating plates 8 are symmetrically and rotatably connected to the lower end of the housing 1 near the opening. Gears 82 are fixedly connected to the rotating plates 8 and housing 1 at the rotatable connection point, meshing with each other. A guide plate 81 is fixedly connected to the side of the rotating plate 8 away from housing 1. The guide plates 81 are inclined, with the ends of the two guide plates 81 furthest from each other at the lower end, leaving space between them for the rubber rings to fall. Rubber rings in the middle of the conveyor belt 32 can fall into the vibrating feed plate 2 through this gap. Rubber rings near the sides of the conveyor belt 32 will first fall onto the guide plates 81 and then slide down the inclined surface of the guide plates 81 onto the vibrating feed plate 2. This prevents excessive accumulation of rubber rings near housing 1 on the vibrating feed plate 2, which would increase the difficulty of organizing and conveying the rubber rings. A support rod 6 is provided on the lower side of one of the guide plates 81, and a reciprocating mechanism 9 is provided on the support rod 6. When the displacement... When mechanism 7 drives the two moving blocks 5 to move relative to each other, displacement mechanism 7 drives reciprocating mechanism 9, which in turn drives support rod 6 to move up and down. The moving support rod 6 drives guide plate 81 to swing up and down on one side of box 1. When support rod 6 moves obliquely upward, it pushes one of the guide plates 81 and rotating plate 8 to rotate upward. Through the meshing transmission of two gears 82, the other rotating plate 8 drives the other guide plate 81 to rotate upward synchronously. When support rod 6 moves obliquely downward, the guide plate 81 on the upper side of support rod 6 rotates back to its original position under the action of gravity. Similarly, the other guide plate 81 also rotates back to its original position. This causes the two guide plates 81 to swing when the rake rod 51 flattens the rubber ring. When the rubber ring slides down the inclined surface of the guide plate 81, the two swinging guide plates 81 lay the rubber ring horizontally on the vibrating feed plate 2 away from the center. Through the spiral conveying of the rubber ring by the vibrating feed plate 2, the rubber ring is more evenly distributed on the vibrating feed plate 2.

[0036] The structure of reciprocating mechanism 9 is detailed below, referring to... Figure 4 The reciprocating mechanism 9 includes a connecting plate 91 fixedly connected to one end of the support rod 6. A guide sleeve 92 is slidably sleeved on the connecting plate 91. The guide sleeve 92 is fixedly set on one side of the housing 1. Both the guide sleeve 92 and the connecting plate 91 are inclined, so that the connecting plate 91 can only move obliquely along the inner wall of the guide sleeve 92. A sleeve frame 93 is fixedly connected to the end of the connecting plate 91 away from the support rod 6. The end of the rotating rod 71 away from the second motor 73 passes through the side wall of the housing 1 and is fixedly connected to an eccentric wheel 75. The eccentric wheel 75 is set inside the sleeve frame 93. When the rotating rod 71 rotates, it drives the eccentric wheel 75 to rotate. The rotating eccentric wheel 75 pushes the sleeve frame 93 to move, so that the sleeve frame 93 drives the connecting plate 91 and the support rod 6 to move obliquely back and forth, thereby making the two guide plates 81 swing when the rotating rod 71 rotates.

[0037] When the infrared light emitted by the infrared sensor 43 is blocked by the strip 44, the infrared sensor 43 sends an electrical signal to the control device, which starts the first motor 31, causing the conveyor belt 32 to rotate and fill the vibrating feeding plate 2 with rubber rings. During the process of conveying the rubber rings by the conveyor belt 32, the horizontally moving rake 51 can flatten the rubber rings on the conveyor belt 32 before they are conveyed to the vibrating feeding plate 2, thereby avoiding the accumulation of rubber rings. At the same time, while the rake 51 moves the rubber rings, the reciprocating mechanism 9 drives the two guide plates 81 to move up and down, so that the rubber rings are dispersed by the guide plates 81, making the rubber rings in the vibrating feeding plate 2 evenly distributed, thus improving the efficiency of the vibrating feeding plate 2 in sorting and conveying rubber rings.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
