Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold processing technology, and in particular to a rotary material handling device for mold processing. Background Technology
[0002] The rotary material handling device for mold processing is an automated equipment that integrates mechanical transmission, automatic control and material handling functions. It is mainly used to pick up, transfer and position workpieces in the mold processing production line. The rotary mechanism drives the material handling execution component to move along a preset trajectory to accurately pick up materials from the processing station, silo or conveyor line and transfer them to the designated position, thereby replacing manual operation and improving production efficiency and accuracy.
[0003] Existing rotary material handling devices for mold processing reduce manual operation steps, lower the labor intensity of workers, and also reduce the errors and safety risks that may be caused by manual material handling, thus improving production safety. However, fixed fixtures cannot adapt to irregularly shaped workpieces, which can easily lead to unstable gripping, workpiece deformation, or gripping failure. Existing technologies are designed for irregular workpieces and can flexibly combine matrix-type multi-degree-of-freedom adjustment modules and plug-in functional modules. For example, flexible finger modules are used when gripping curved workpieces. However, fixtures need to be changed for different workpieces, which is cumbersome to debug and has low production efficiency. Utility Model Content

[0030] 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.
[0031] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model provides a rotary material handling device for mold processing, including a column 1, a support arm 2 provided on the top wall of the column 1, a hydraulic rod 3 provided on the bottom left side of the support arm 2, a material handling mechanism 4 provided at the bottom of the hydraulic rod 3, the material handling mechanism 4 being used to pick up and put down materials, a moving mechanism 5 provided inside the support arm 2, the moving mechanism 5 being used to move the hydraulic rod 3, and a rotating mechanism 6 installed on the top wall of the column 1, the rotating mechanism 6 being used to rotate the support arm 2.
[0032] The material handling mechanism 4 includes a fixed block 401, which is fixedly connected to the output end of the hydraulic rod 3. The hydraulic rod 3 drives the fixed block 401 to move up and down, so that the clamping block 4074 can accurately reach the height of the material. The inside right side of the fixed block 401 is fixedly connected to a motor 402. The output end of the motor 402 is fixedly connected to a universal joint 403. The end of the universal joint 403 is fixedly connected to a bidirectional threaded rod 404. The motor 402 drives the bidirectional threaded rod 404 to rotate through the universal joint 403. Threaded blocks 405 are threadedly connected to the left and right sides of the outer wall of the bidirectional threaded rod 404. A square groove 406 is opened in the middle of the bottom wall of the fixed block 401. An elastic clamping component 407 is provided at the bottom of the hydraulic rod 3.
[0033] The elastic clamping assembly 407 includes a second fixed block 4071, which is fixedly connected to the bottom wall of the threaded block 405. The threaded block 405 drives the second fixed block 4071 to move in the material direction. The outer wall of the second fixed block 4071 is provided with a plurality of square grooves 4072 at equal intervals. A spring 4073 is installed on the inner wall of the square groove 4072. A clamping block 4074 is installed at the end of the spring 4073. The threaded block 405 is slidably connected to the inner wall of the first square groove 406. The clamping block 4074 is slidably connected to the second square groove 4072. The spring 4073 in the second square groove 4072 pushes the clamping block 4074 to contact the mold. The second spring 4073 clamps the material elastically.
[0034] Specifically, during the material handling process, motor 402 is first started. Motor 402 drives the bidirectional threaded rod 404 to rotate through universal joint 403, which in turn causes the threaded block 405 to move synchronously relative to the material in square groove 406. The movement of the threaded block 405 drives the fixed block 4071 to move towards the material. At the same time, the spring 4073 in square groove 4072 pushes the clamping block 4074 to contact the mold. The spring 4073 clamps the material through elasticity. For irregularly shaped materials, the clamping block 4074 can make slight floating according to the material contour, thereby increasing the clamping range and improving the applicability of the device.
[0035] Reference Figure 2 and Figure 5 The moving mechanism 5 includes a square groove 3 501, which is formed on the bottom wall of the support arm 2. The hydraulic rod 3 is set inside the square groove 3 501. The upper middle part of the front and rear sides of the outer wall of the hydraulic rod 3 is fixedly connected to the slider 1 503. The front and rear sides of the inner wall of the square groove 3 501 are provided with sliding grooves 502, which are slidably connected to the slider 1 503. The slider 1 503 outside the hydraulic rod 3 slides in the sliding groove 502 inside the square groove 3 501, providing guidance and stable support for the movement of the hydraulic rod 3. The support arm 2 is provided with a drive assembly 504.
[0036] The drive assembly 504 includes a second motor 5041, which is fixedly connected inside the support arm 2. A gear 5042 is fixedly connected to the output end of the second motor 5041. The second motor 5041 drives the gear 5042 to rotate. A rack 5043 is fixedly connected to the front side of the top wall of the hydraulic rod 3. The rack 5043 meshes with the gear 5042, and the gear 5042 drives the rack 5043 to move. A square groove 4 5044 is opened in the lower middle part of the front side of the inner wall of the square groove 3 501. The square groove 3 501 is slidably connected to the hydraulic rod 3, and the rack 5043 is slidably connected to the square groove 4 5044. The square groove 4 5044 provides sliding space for the rack 5043 and provides lateral constraint to ensure stability and accuracy during transmission.
[0037] Specifically, after starting motor 2 5041, motor 2 5041 drives gear 5042 to rotate. Gear 5042 moves rack 5043 through transmission mechanism. Rack 5043 then pushes hydraulic rod 3 to move laterally in square groove 3 501. At the same time, slider 1 503 on the outside of hydraulic rod 3 slides in groove 502 in square groove 3 501, providing guidance and stable support for the movement of hydraulic rod 3, ensuring the accurate and smooth movement of hydraulic rod 3 in the horizontal direction, so that it can reach the target position to grab or place materials.
[0038] Reference Figure 2 , Figure 3 and Figure 4The rotating mechanism 6 includes a motor 601, which is fixedly connected to the top wall of the column 1. The output end of the motor 601 is fixedly connected to a turntable 602, which is fixedly connected to the right side of the bottom wall of the support arm 2. The motor 601 drives the turntable 602 to rotate, and the turntable 602 drives the support arm 2 to rotate around the column 1 as the axis, so that the hydraulic rod 3 and the material picking mechanism 4 installed at the bottom of the support arm 2 change their orientation. The material or mold station in different positions can be aligned without moving the entire equipment. The bottom wall of the fixed block 401 is provided with a slide rail 7. Two slide rails 7 are fixedly connected to the front and rear sides of the bottom wall of the fixed block 401. The inner wall of the slide rail 7 is slidably connected to a slider 8, which is fixedly connected to the front and rear sides of the top wall of the fixed block 4071. The fixed block 4071 slides on the slide rail 7 through the slider 8, which improves the adaptability of clamping.
[0039] Specifically, motor 601 drives turntable 602 to rotate, and turntable 602 drives support arm 2 to rotate around column 1, causing hydraulic rod 3 and material handling mechanism 4 installed at the bottom of support arm 2 to change orientation. This allows the equipment to be aligned with materials or mold positions in different directions without the need for overall equipment movement. Fixing block 4071 slides on slide rail 7 via slider 8, improving the adaptability of clamping.
[0040] Working principle: When picking up materials, start motor 402. Motor 402 drives bidirectional threaded rod 404 to rotate through universal joint 403. Bidirectional threaded rod 404 drives threaded block 405 to move synchronously in opposite directions in square groove 406. Threaded block 405 drives fixed block 4071 to move in the direction of the material. Spring 4073 in square groove 4072 pushes clamping block 4074 to contact the mold. Spring 4073 clamps the material elastically. For irregular materials, clamping block 4074 can float slightly with the material outline to expand the clamping range. There is no need to frequently change the clamps, which improves the device's versatility for materials of various specifications.
[0041] When motor 2 (5041) is started, it drives gear 5042 to rotate. Gear 5042 drives rack 5043 to move. Rack 5043 drives hydraulic rod 3 to move laterally within square groove 3 (501). At the same time, slider 1 (503) outside hydraulic rod 3 slides in groove 502 within square groove 3 (501), providing guidance and stable support for the movement of hydraulic rod 3. This enables precise and smooth horizontal movement of hydraulic rod 3, allowing it to reach the target position for material grabbing or placement.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
