Description

Technical Field

[0001] This utility model relates to the technical field of sprue material sensing devices, specifically a device for sensing and opening a sprue outlet. Background Technology

[0002] In the injection molding industry, sprue material typically includes sprues, defective products in the process, mechanical adjustment parts, and material heads from mechanical adjustments. The addition of sprue material depends on the product's function, purpose, stress conditions, and appearance requirements. Sometimes, the sprue at the bottom of the bottle is stuck and not removed. After being picked up by the robotic arm and placed on the conveyor belt, the bottle can easily get stuck on the conveyor belt because the sprue is at the bottom, affecting production. It is also inconvenient to adjust the height of the photoelectric sensor to inspect the bottle, resulting in poor flexibility and potentially affecting its use.

[0003] Therefore, we propose a drain inlet sensor-activated opening device to improve upon the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for induction opening of a drain outlet, in order to solve the problems mentioned in the background art, such as the inconvenience of adjusting the height of the photoelectric sensor to detect bottles, poor flexibility, and easy impact on use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for induction-activated opening of a drain outlet, comprising a detection photocell, an upper sleeve installed at the bottom end of the detection photocell, a connecting wire installed at the rear end of the detection photocell, a lower sleeve provided at the bottom end of the upper sleeve, a mounting plate fixedly connected to the bottom end of the lower sleeve, a bidirectional screw provided inside the lower sleeve and the upper sleeve, a fixing sleeve fixedly connected at the middle position of the outer side of the bidirectional screw, a guide rod fixedly connected to the right side of the top of the mounting plate, and a limit block fixedly connected to the bottom right side of the upper sleeve.

[0006] As a further technical solution of this utility model, the limiting block is disposed outside the guide rod, and the limiting block slides up and down outside the guide rod. The internal components of the detection photoelectric eye include a light source module, a photoelectric receiver, and a processing module.

[0007] As a further technical solution of this utility model, the external threads at the upper and lower ends of the bidirectional screw are opposite, and the upper sleeve and the lower sleeve are respectively machined with internal threads. The lower sleeve and the upper sleeve respectively cooperate with the bidirectional screw. The internal and external threads are standard trapezoidal threads, and their thread helix angle is less than the equivalent friction angle. This structure naturally has self-locking characteristics.

[0008] As a further technical solution of this utility model, a frame is fixedly connected to the front end of the top of the detection photoelectric sensor, a guide groove is opened at the front end of the frame, a slider is provided inside the frame, a connecting block is fixedly connected to the front end of the slider, a protective plate is fixedly connected to the front end of the connecting block, a protective pad is fixedly connected to the rear end of the protective plate, and the protective plate is set at the top of the front end of the detection photoelectric sensor.

[0009] As a further technical solution of this utility model, the bottom end of the mounting plate is provided with a base, and a mounting block is fixedly connected to the middle position of the top end of the base. Spring grooves are opened on the left and right sides inside the mounting plate. A movable plate is provided on the left side inside the spring groove. A limit rod is fixedly connected to the side of the movable plate near the middle. A connecting rod is fixedly connected to the side of the movable plate near the outside. A pull plate is fixedly connected to the side of the connecting rod near the outside. A limit spring is fixedly connected between the movable plate and the spring groove. Limit grooves are opened on the left and right sides inside the mounting block. The mounting plate is set outside the mounting block.

[0010] As a further technical solution of this utility model, the limiting groove is provided in multiple sets, the limiting rod is embedded inside the limiting groove, and the limiting spring is provided outside the connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the device for induction opening of the drain outlet not only makes it easy to adjust the height to detect the drain material and makes it easy to protect the detection photoelectric eye, but also makes it easy to install the device;

[0012] (1) By setting a guide rod, a limit block, an upper sleeve, a lower sleeve, a bidirectional screw and a fixed sleeve, when the height of the detection photoelectric eye needs to be adjusted according to the requirements, the fixed sleeve is rotated. The fixed sleeve drives the bidirectional screw to rotate inside the upper sleeve and the lower sleeve, so that the upper sleeve can drive the detection photoelectric eye to rise and fall. The guide rod and the limit block can limit the upper sleeve. Adjusting the height of the detection photoelectric eye can facilitate the sensing of the water nozzles at different bottle bottoms. When the detection photoelectric eye senses the material outlet, the robot arm is automatically released, so that the bottle with the water nozzle falls into the water nozzle material box and will not be sent to the conveyor belt.

[0013] (2) By setting up a protective plate, frame, guide groove, connecting block and slider, the protective plate can protect the detection photoelectric eye at the top of the front end of the detection photoelectric eye. When the detection photoelectric eye needs to be used, push the connecting block. The connecting block drives the protective plate and slider to slide to one side to make the induction at the front end of the detection photoelectric eye leak out. The slider at the rear end of the connecting block slides inside the frame to limit the position of the protective plate.

[0014] (3) By setting up an installation plate, a limiting rod, a limiting groove, a movable plate, a spring groove, a limiting spring, a pull plate and a connecting rod, when it is necessary to install the installation plate on the outside of the installation block, pull the pull plate to lock the installation plate on the outside of the installation block. Then, adjust the distance of the detection photoelectric sensor according to the requirements. After adjustment, release the pull plate. The limiting spring uses its own elasticity to make the limiting rod embedded in the limiting groove to limit and fix the installation plate. Limiting and fixing the installation plate not only makes the installation plate installed on the outside of the installation block, but also prevents the installation plate from accidentally sliding on the outside of the installation block.

[0020] 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.

[0021] Please see Figure 1-4This utility model provides an embodiment of a drain outlet sensor opening device, including a detection photocell 1, an upper sleeve 10 installed at the bottom end of the detection photocell 1, a connecting wire 7 installed at the rear end of the detection photocell 1, a lower sleeve 11 provided at the bottom end of the upper sleeve 10, a mounting plate 14 fixedly connected to the bottom end of the lower sleeve 11, a bidirectional screw 15 provided inside the lower sleeve 11 and the upper sleeve 10, a fixing sleeve 16 fixedly connected at the middle position of the outside of the bidirectional screw 15, a guide rod 8 fixedly connected to the right side of the top end of the mounting plate 14, and a limit block 9 fixedly connected to the bottom right side of the upper sleeve 10.

[0022] The limiting block 9 is set outside the guide rod 8 and slides up and down outside the guide rod 8. The internal components of the detection photoelectric eye 1 include a light source module, a photoelectric receiver and a processing module. The external threads at the upper and lower ends of the bidirectional screw 15 are opposite. The upper sleeve 10 and the lower sleeve 11 are respectively machined with internal threads. The lower sleeve 11 and the upper sleeve 10 respectively cooperate with the bidirectional screw 15. The internal and external threads are standard trapezoidal threads, and their thread helix angle is less than the equivalent friction angle. This structure naturally has self-locking characteristics.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, when the height of the photoelectric sensor 1 needs to be adjusted according to requirements, the fixed sleeve 16 is rotated. The fixed sleeve 16 drives the bidirectional screw 15 to rotate inside the upper sleeve 10 and the lower sleeve 11, so that the upper sleeve 10 can drive the photoelectric sensor 1 to rise and fall. The guide rod 8 and the limit block 9 can limit the upper sleeve 10. Adjusting the height of the photoelectric sensor 1 can facilitate the sensing of the water nozzles at different bottle bottoms. When the photoelectric sensor 1 senses the water nozzle, the robot arm is automatically released, causing the bottle with the water nozzle to fall into the water nozzle hopper and not be sent to the conveyor belt.

[0024] A frame 3 is fixedly connected to the front end of the top of the photoelectric sensor 1. A guide groove 4 is provided at the front end of the frame 3. A slider 6 is provided inside the frame 3. A connecting block 5 is fixedly connected to the front end of the slider 6. A protective plate 2 is fixedly connected to the front end of the connecting block 5. A protective pad 17 is fixedly connected to the rear end of the protective plate 2. The protective plate 2 is located at the top of the front end of the photoelectric sensor 1.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, the protective plate 2 can protect the detection photoelectric sensor 1 at the top of the front end of the detection photoelectric sensor 1. When the detection photoelectric sensor 1 needs to be used, push the connecting block 5. The connecting block 5 drives the protective plate 2 and the slider 6 to slide to one side to expose the sensing at the front end of the detection photoelectric sensor 1. The slider 6 at the rear end of the connecting block 5 can limit the position of the protective plate 2 by sliding inside the frame 3.

[0026] The mounting plate 14 has a base 12 at its bottom end, and a mounting block 13 is fixedly connected to the middle position of the top of the base 12. Spring grooves 21 are opened on the left and right sides inside the mounting plate 14. A movable plate 20 is set on the left side inside the spring groove 21. A limit rod 18 is fixedly connected to the side of the movable plate 20 near the middle. A connecting rod 24 is fixedly connected to the side of the movable plate 20 near the outside. A pull plate 23 is fixedly connected to the side of the connecting rod 24 near the outside. A limit spring 22 is fixedly connected between the movable plate 20 and the spring groove 21. Limit grooves 19 are opened on the left and right sides inside the mounting block 13. The mounting plate 14 is set outside the mounting block 13. Multiple sets of limit grooves 19 are provided. The limit rod 18 is embedded in the limit groove 19. The limit spring 22 is set outside the connecting rod 24.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, when the mounting plate 14 needs to be installed outside the mounting block 13, pull the pull plate 23 to lock the mounting plate 14 outside the mounting block 13. Then, adjust the distance of the photoelectric sensor 1 as needed. After adjustment, release the pull plate 23. The limit spring 22 uses its own elasticity to make the limit rod 18 embedded in the limit groove 19 to limit and fix the mounting plate 14. Limiting and fixing the mounting plate 14 not only ensures that the mounting plate 14 is installed outside the mounting block 13, but also prevents the mounting plate 14 from accidentally sliding outside the mounting block 13.

[0028] Working Principle: When using this invention, pulling the pull plate 23 secures the mounting plate 14 to the outside of the mounting block 13. Then, the distance to the photoelectric sensor 1 is adjusted as needed. After adjustment, the pull plate 23 is released. The limiting spring 22, through its elasticity, causes the limiting rod 18 to embed inside the limiting groove 19, thus limiting and fixing the mounting plate 14. This not only ensures the mounting plate 14 is installed outside the mounting block 13 but also prevents accidental sliding. When adjusting the height of the photoelectric sensor 1, rotating the fixing sleeve 16 causes the bidirectional screw 15 to rotate inside the upper sleeve 10 and lower sleeve 11, allowing the upper sleeve 10 to raise and lower the photoelectric sensor 1. The guide rod 8 and the limiting block 9 limit the upper sleeve 10. Adjusting the height of the photoelectric sensor 1 facilitates sensing the nozzles of different bottle bottoms. The protective plate 2 at the top of the front end of the photoelectric sensor 1 protects it. When the photoelectric sensor 1 is activated, it pushes the connecting block 5. The connecting block 5 causes the protective plate 2 and the slider 6 to slide to one side, making the sensing of the front end of the photoelectric sensor 1 visible. The slider 6 at the rear end of the connecting block 5 slides inside the frame 3, which can limit the movement of the protective plate 2. When the bottom of the bottle moves to the front end of the photoelectric sensor 1, the light source inside the photoelectric sensor 1 will emit light of a certain intensity and wavelength. This light can be visible light or invisible light such as infrared light. After passing through a specific lens system, the light emitted by the light source is focused and illuminates the object to be detected. If the object exists and is in the correct position, the light will be reflected or transmitted back by the object. The photoelectric receiver is responsible for receiving the light signal reflected or transmitted back from the object. When a light signal of sufficient intensity is received, the receiver will generate a corresponding electrical signal output. The signal processing circuit can determine whether the object exists and whether the position is correct. When the photoelectric sensor 1 senses the sprue, it causes the robot arm to automatically release, causing the bottle with the sprue to fall into the sprue hopper and not be sent to the conveyor belt.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
