Description

Technical Field

[0001] This utility model provides a flipping and sensing device, and particularly relates to a mold material taking flipping and through-beam sensing device. Background Technology

[0002] In the field of mold processing and product post-processing, the mold picking and flipping and photoelectric sensing device is used to grab the molded product from the mold exit, flip the product to adjust its posture, and detect the product's position and status through the sensing device to cooperate with subsequent processes. Its main function is to realize the automated transfer, posture adjustment and precise positioning of the product from the mold to the next stage, reduce manual intervention, improve production continuity and efficiency, and is widely used in manufacturing industries such as injection molding and stamping.

[0003] Existing mold material handling, flipping, and photoelectric sensing devices typically consist of a simple robotic arm, a manual flipping table, and a single photoelectric switch. The robotic arm handles materials along a fixed trajectory, resulting in poor flexibility and difficulty in adapting to different product specifications. The flipping table relies on manual operation or simple cylinder drive, leading to low flipping angle accuracy and potential product posture deviations. The sensing devices are mostly single-point detectors, susceptible to ambient light interference, and lack sufficient detection accuracy. Each component operates independently, lacking a unified control system. The material handling, flipping, and conveying processes are loosely connected, often resulting in product drops and inaccurate positioning. Furthermore, the lack of monitoring to ensure accurate material handling and flipping makes it impossible to detect anomalies in a timely manner. These shortcomings make existing devices unable to meet the demands of high-precision and highly automated production. Compared with this application, they are significantly inferior in terms of structural integration, motion accuracy, and sensing reliability. Utility Model Content

[0029] like Figure 1 and Figure 2 As shown, the main structure and material handling and flipping components of a mold material handling and flipping device include a support plate 11 that is connected to the outlet of the extrusion molding mold 1.

The sliding seat 22 is slidably connected to the transverse slide rail 21. A material handling plate 24 is fixedly connected above the sliding seat 22. The drive cylinder 23 is installed at the bottom of the material handling plate 24. The flipping mechanism 3 consists of a rotary cylinder 31 and a finger gripper cylinder 32 connected to the output shaft of the rotary cylinder 31. The rotary cylinder 31 and the finger gripper cylinder 32 are both installed on both sides of the drop hopper 13 on the support plate 11. The drop hopper 13 is located below the flipping path of the flipping mechanism 3. The production line 14 is located at the bottom outlet of the drop hopper 13.

[0030] In this implementation scheme, the support plate 11 is connected to the outlet of the extrusion molding die 1. The externally mounted frame 12 is equipped with components such as the drive module 2 and the flipping mechanism 3. The transverse slide rail 21 of the drive module 2 is mounted on the top of the support plate 11, and the sliding seat 22 is slidably connected to it. The bottom of the upper material picking plate 24 is equipped with a drive cylinder 23. The rotary cylinder 31 and the finger gripper cylinder 32 of the flipping mechanism 3 are located on both sides of the drop hopper 13, which is situated below the flipping path. The production line 14 is located at its bottom outlet. From the key implementation points, the drive module 2 achieves smooth movement of the material picking plate 24 through the transverse slide rail 21 and the sliding seat 22, while the drive cylinder 23 ensures stable material picking, solving the problem of inflexible traditional material picking. The rotary cylinder 31 of the flipping mechanism 3 drives the finger gripper cylinder 32 to precisely flip the product, ensuring proper posture adjustment and improving flipping accuracy. In terms of innovation, the components are arranged in an orderly manner around the support plate 11 and the frame 12. The material picking, turning and conveying links are closely connected. The turning mechanism 3 and the drop hopper 13 work together to achieve efficient product transfer, effectively solving the problems of loose links and turning deviation in existing devices, and improving production continuity and reliability.

[0031] like Figure 3 , 4As shown in Figure 5, the sensing and positioning related structures of the device include a through-beam photoelectric sensor 15 and a positioning clamp 16 provided in the positioning area of ​​the production line 14. The through-beam photoelectric sensor 15 includes a transmitter and a receiver, which are respectively installed on the brackets on both sides of the production line 14 and arranged opposite to each other. The positioning clamp 16 includes two L-shaped clamps arranged opposite to each other and a drive cylinder 23. The drive cylinder 23 is connected to the L-shaped clamps. A diffuse reflection sensor is provided at the material picking plate 24. The diffuse reflection sensor is electrically connected to the control system. The control system is used to control the movement of the drive module 2, the clamping action of the drive cylinder 23, the flipping action of the flipping mechanism 3, and the positioning action of the positioning clamp 16.

[0032] In this implementation scheme, the through-beam photoelectric sensor 15 in the positioning area of ​​production line 14 includes a transmitter and a receiver, which are respectively mounted on the supports on both sides of production line 14 and arranged opposite each other. The two L-shaped clamps of the positioning clamp 16 are connected by a drive cylinder 23. The diffuse reflection sensor at the material picking plate 24 is electrically connected to the control system. The control system controls the actions of the drive module 2, the drive cylinder 23, etc. From the key points of implementation, the through-beam photoelectric sensor 15 accurately senses the product through the cooperation of the transmitter and receiver, solving the problem of inaccurate sensing in traditional methods; the L-shaped clamps of the positioning clamp 16 achieve stable initial positioning of the product under the drive of the drive cylinder 23, improving positioning accuracy; the diffuse reflection sensor monitors the material picking status in real time to ensure accurate material picking. From the perspective of innovation, the sensing device and the positioning structure work together to form a closed-loop control with the control system, so that the sensing, positioning, material picking, and flipping links are linked, solving the drawbacks of independent operation of each part of the existing device, and further improving the automation level and operational stability of the device.

[0033] When using this device, a clean and stable compressed air supply is required from an existing air source processor (including a filter, pressure reducing valve, and lubricator) to provide to the drive cylinder 23, rotary cylinder 31, and finger gripper cylinder 32. The cylinder barrel of the drive cylinder 23 can be made of 45# seamless steel pipe to enhance durability. The through-beam photoelectric sensor 15, diffuse reflection sensor, and control system are powered by an existing switching power supply. The output voltage of the switching power supply is set to 24V DC to ensure the safety of electronic components. The transmitter and receiver of the through-beam photoelectric sensor 15 can be infrared to improve anti-interference capability. In addition, the signals of each sensor are transmitted to the control system using an existing industrial bus, with waterproof connectors for connecting cables. The rotating shaft of the rotary cylinder 31 can be made of 40Cr material to enhance wear resistance. These existing technologies work together with this device to ensure the overall high efficiency and stability of operation.

[0034] Specifically, during installation, the transmitter and receiver of the through-beam photoelectric sensor 15 are fixed to aluminum alloy brackets on both sides of the production line 14 using hexagonal socket head cap screws. The brackets are connected to the ground via expansion bolts to ensure alignment of the transmitter and receiver optical paths. The cylinder body of the drive cylinder 23 of the positioning clamp 16 is connected to the table surface of the production line 14 via a flange. The L-shaped clamp plate and the cylinder piston rod are connected by threads and fitted with anti-loosening nuts. The existing PLC control cabinet is connected to the diffuse reflection sensor and control system via shielded cables, and an intermediate relay is installed inside the cabinet to amplify the signal. During use, the working pressure of the drive cylinder 23 is first adjusted to 0.5-0.7MPa using the existing air pressure adjustment knob. After the through-beam photoelectric sensor 15 is connected to a 24V DC power supply, the sensing sensitivity needs to be tested by blocking the light path with a calibration block. The detection distance of the diffuse reflection sensor is adjusted to 50-100mm using the existing potentiometer. During operation, after the control system receives the sensor signal, it controls the cylinder action through a solenoid valve to complete the sensing and positioning linkage of the product.

Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
