Description

Technical Field

[0001] This utility model relates to the field of temperature sensor manufacturing technology, and more specifically, to a temperature sensor housing positioning and feeding 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] A pressing device is required when pressing the rubber ring into the outer shell 4 of the temperature sensor. Before pressing the rubber ring, the outer shell 4 needs to be placed on the pressing device. A feeding device for placing the outer shell 4 consists of a vibrating conveyor and a transfer robot. After the outer shell 4 is transported from one end of the vibrating conveyor to the other end, the transfer robot places the outer shell 4 onto the pressing device. However, the outer shell 4 consists of a spindle-shaped base plate and a sleeve fixed at the center of the upper side of the base plate. Positioning holes 41 are opened near both ends of the base plate of the outer shell. When the outer shell 4 moves in the slide of the vibrating conveyor 1, the opposite sides of the spindle-shaped base plate of the outer shell 4 cannot completely fit the side walls of the slide, causing the outer shell 4 to tilt during the conveying process. When the outer shell 4 is transported to the end of the vibrating conveyor near the transfer robot, the position of the tilted outer shell 4 is uncontrollable, which will cause the transfer robot to be unable to stably pick up the outer shell 4, affecting the normal operation of the rubber ring pressing production line. Utility Model Content

[0004] The purpose of this invention is to provide a temperature sensor housing positioning and feeding device 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 temperature sensor housing positioning and feeding device, including a vibrating conveyor. The top of the vibrating conveyor has a slide rail, the interior of which is used to transport the housing. A finger cylinder is fixedly installed on one side of the vibrating conveyor. Two grippers are symmetrically rotated on the top of the finger cylinder. An extension rod is fixedly connected to the upper end of each gripper. The central axis between the two extension rods and the central axis of the slide rail are located on the same vertical plane. When one end of the housing moves to the outside of the slide rail, the two grippers of the finger cylinder close together. The closing grippers respectively drive the two extension rods to move closer together, so that the sidewalls of the two extension rods contact the two sides of the housing. A transfer mechanism is provided on one side of the vibrating conveyor. When both extension rods are in contact with the housing, the transfer mechanism lifts the housing upwards, causing the housing to move out of the slide rail.

[0006] As a further improvement to this technical solution, the transfer mechanism includes a vertical frame disposed on one side of the vibrating conveyor, a movable frame slidably disposed on one side of the vertical frame near the top, a first telescopic rod disposed on one side of the movable frame for driving the movable frame to move laterally, the first telescopic rod being fixedly installed on the vertical frame, a second telescopic rod being fixedly installed on the top of the movable frame, and a vacuum suction cup being fixedly installed at the lower end of the piston rod of the second telescopic rod through the movable frame.

[0007] As a further improvement to this technical solution, a limiting rod is provided between the two extension rods, and a lifting assembly is provided between the limiting rod and the two grippers. When the two grippers close, the lifting assembly drives the limiting rod to move vertically upward. When both extension rods rotate to the position of contact with the outer shell, the upper end of the limiting rod is inserted into the positioning hole.

[0008] As a further improvement to this technical solution, the lifting assembly includes a slider slidably disposed on one side of the vibrating conveyor, the lower end of the limiting rod is fixedly disposed on the slider, and two connecting rods are symmetrically hinged on opposite sides of the slider. The other ends of the two connecting rods are respectively hinged to the side of the two grippers that are close to each other. The connecting rods are inclined, and the end of the connecting rod closer to the slider is located at a higher position.

[0009] As a further improvement to this technical solution, an infrared sensor is fixedly installed on the bottom surface inside the slide. When the outer shell is conveyed in the slide towards the finger cylinder, the outer shell passes over the infrared sensor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The temperature sensor housing positioning and feeding device, when the outer shell is vibrated and conveyed to the outside of the slide at one end, causes the two grippers to drive the two extension rods to rotate to the position of contact with the opposite sides of the outer shell, so as to align and correct the outer shell, facilitate the vacuum suction cup to adsorb and fix the outer shell, and transfer the outer shell to the pressing equipment in the predetermined position for processing, meet the requirements of the rubber ring pressing production line for the placement of the outer shell, and ensure the normal operation of the rubber ring pressing production line.

[0012] 2. In this temperature sensor housing positioning and feeding device, when the two extension rods that are close to each other correct the outer housing, the two extension rods drive the limiting rod to move vertically upward through the two connecting rods, so that the limiting rod contacts the side of the inner wall of the positioning hole away from the vibrating conveyor, thereby restricting the outer housing from moving slightly away from the finger cylinder, improving the stability of the outer housing after the two extension rods position the outer housing, and facilitating the transfer mechanism to transfer the outer housing to the pressing equipment station.

[0026] 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.

[0027] Example 1

[0028] Please refer to Figure 6 Because the opposite sides of the spindle-shaped base plate of the outer shell 4 cannot fully fit the two side walls inside the slide, the outer shell 4 will be tilted during the conveying process. When the outer shell 4 is conveyed to the end of the vibrating conveyor that is close to the transfer robot, the position of the tilted outer shell 4 is uncontrollable, which will cause the transfer robot to be unable to stably pick up the outer shell 4.

[0029] To avoid the above problems, please refer to Figures 1-5As shown, one of the objectives of this embodiment is to provide a temperature sensor housing positioning and feeding device, including a vibrating conveyor 1. A slide rail 11 is provided on the top of the vibrating conveyor 1, and the interior of the slide rail 11 is used to transport the housing 4. A finger cylinder 2 is fixedly installed on one side of the vibrating conveyor 1. A feeding device is provided on the side of the vibrating conveyor 1 away from the finger cylinder 2 for placing the housing 4 into the slide rail 11. After the feeding device places the housing 4 into the slide rail 11, the vibrating conveyor 1 transports the housing 4 along the slide rail 11 towards the finger cylinder 2. Two clamps are symmetrically rotated on the top of the finger cylinder 2. The upper end of the claw 21 is fixedly connected to an extension rod 22. The central axis between the two extension rods 22 and the central axis of the slide 11 are located on the same vertical plane. An infrared sensor 12 is fixedly installed on the bottom surface inside the slide 11. The infrared sensor 12 is electrically connected to the finger cylinder 2. When the outer shell 4 is conveyed in the slide 11 towards the finger cylinder 2, the outer shell 4 passes above the infrared sensor 12. At this time, the outer shell 4 blocks the infrared rays emitted by the infrared sensor 12. The infrared sensor 12 sends an electrical signal to the finger cylinder 2, causing the two claws 21 of the finger cylinder 2 to close after a preset delay. After one end of the outer shell 4 moves to the outside of the slide rail 11, the two grippers 21 of the finger cylinder 2 close. The two grippers 21, while closing, drive the two extension rods 22 closer together. If the outer shell 4 is biased towards one of the extension rods 22 at this time, that extension rod 22 will push the outer shell 4 to move. Since the central axis between the two extension rods 22 and the central axis of the slide rail 11 are located on the same vertical plane, when the sidewalls of the two extension rods 22 contact the opposite sides of the outer shell 4, the two extension rods 22 correct the outer shell 4, making the central axis of the outer shell 4 and the central axis of the slide rail 11 located on the same vertical plane. At this time, the two... The extension rods 22 are positioned on the two inclined sides of the spindle-shaped base plate of the outer shell 4. The middle position of the spindle-shaped base plate of the outer shell 4 is located on the side of the extension rods 22 closer to the vibrating conveyor 1. Therefore, the two extension rods 22 will prevent the outer shell 4 from being conveyed away from the feeding device by the vibrating conveyor 1. This allows the two extension rods 22 to position the outer shell 4, making it convenient for the transfer mechanism 3, which is set on one side of the vibrating conveyor 1, to transfer the outer shell 4 to the pressing equipment at a predetermined position for processing. This meets the requirements of the rubber ring pressing production line for the placement of the outer shell 4 and ensures the normal operation of the rubber ring pressing production line.

[0030] When the two extension rods 22 prevent the outer casing 4 from being conveyed further away from the feeding device by the vibrating conveyor 1, the vibrating conveyor 1 is still running. The vibrating conveyor 1 will cause the outer casing 4 to move irregularly, resulting in a slight movement of the outer casing 4 away from the finger cylinder 2. This causes inconvenience to the transfer mechanism 3 in transferring the outer casing 4. To solve this problem, a limit rod 5 is set between the two extension rods 22. The diameter of the upper end of the limit rod 5 is smaller than the inner diameter of the positioning hole 41. A lifting assembly 6 is set between the limit rod 5 and the two grippers 21. The lifting assembly 6 is used to drive the limit rod 5 to move vertically. The structure of the lifting assembly 6 is detailed below, refer to Figure 5 The lifting assembly 6 includes a slider 61 slidably disposed on one side of the vibrating conveyor 1. Specifically, a vertically arranged groove is provided on one side of the vibrating conveyor 1. A slider corresponding to the groove is fixed on the slider 61. The groove restricts the sliding position of the slider, thereby limiting the vertical movement trajectory of the slider 61. Simultaneously, the lower end of the limiting rod 5 is fixedly disposed on the slider 61. Two connecting rods 62 are symmetrically hinged to opposite sides of the slider 61. The other ends of the two connecting rods 62 are respectively hinged to the sides of two grippers 21 that are close to each other. The connecting rods 62 are inclined, with the ends of the connecting rods 62 closer to the slider 61 at a higher position. When the two grippers 21 close, the two grippers 21 respectively drive the lower ends of the two connecting rods 62 to approach the limiting rod 5, causing the two connecting rods 62 to rotate. The higher ends of the two connecting rods 62 then drive... The limiting rod 5 moves vertically upward. When both extension rods 22 rotate to the position of contact with the outer shell 4, the two extension rods 22 complete the correction of the outer shell 4. At this time, the two extension rods 22 continue to move closer to each other and slide along the inclined side of the bottom plate of the outer shell 4, so that the two extension rods 22 push the outer shell 4 away from the finger cylinder 2. This part of the stroke of the outer shell 4 is controllable. When the positioning hole 41 moves directly above the limiting rod 5, the upper end of the limiting rod 5 is inserted into the interior of the positioning hole 41. At this time, the limiting rod 5 contacts the side of the inner wall of the positioning hole 41 away from the vibrating conveyor 1, so that the limiting rod 5 and the positioning hole 41 cooperate to restrict the outer shell 4 from moving slightly away from the finger cylinder 2, which improves the stability of the outer shell 4 after the two extension rods 22 position the outer shell 4, and facilitates the transfer mechanism 3 to transfer the outer shell 4 to the work station of the pressing equipment.

[0031] The structure of transfer mechanism 3 is detailed below, with reference to... Figure 3The transfer mechanism 3 includes a stand 31 mounted on one side of the vibrating conveyor 1. A movable frame 33 is slidably mounted on one side of the stand 31 near the top. A first telescopic rod 32 for driving the movable frame 33 to move laterally is mounted on one side of the movable frame 33. The first telescopic rod 32 is fixedly mounted on the stand 31. A second telescopic rod 34 is fixedly mounted on the top of the movable frame 33. The lower end of the piston rod of the second telescopic rod 34 passes through the movable frame 33 and is fixedly mounted with a vacuum suction cup 35. When both extension rods 22 are in contact with the outer shell 4, the vacuum suction cup 35 is located directly above the sleeve of the outer shell 4. At this time, the piston rod of the second telescopic rod 34 extends, causing the vacuum suction cup 35 to move downward, so that the lower end of the vacuum suction cup 35 contacts the bottom surface inside the sleeve of the outer shell 4. Then, the inside of the vacuum suction cup 35... A negative pressure is generated, which adsorbs and fixes the outer shell 4 to the lower end of the vacuum suction cup 35. Then, the piston rod of the second telescopic rod 34 retracts, causing the vacuum suction cup 35 to move upward. This allows the vacuum suction cup 35 to lift the outer shell 4, causing it to move out of the slide rail 11. The positioning hole 41 moves out from the outside of the limiting rod 5. Then, the piston rod of the first telescopic rod 32 extends, causing the moving frame 33 to move laterally away from the vibrating conveyor 1. This allows the moving frame 33 to move the second telescopic rod 34, the vacuum suction cup 35, and the outer shell 4 to the top of the pressing equipment station. When the piston rod of the second telescopic rod 34 extends and places the outer shell 4 on the pressing equipment station, the negative pressure inside the vacuum suction cup 35 is removed, allowing the outer shell 4 to be placed on the pressing equipment station for subsequent processing.
