Description

Technical Field

[0001] This invention relates to the field of parts transfer device technology, specifically a metal parts transfer device with a special coating. Background Technology

[0002] Metal parts transfer devices are specialized equipment used to safely and efficiently handle and transport metal parts during manufacturing, processing, or logistics. Their core purpose is to reduce the risks associated with manual handling, prevent damage to parts, improve operational efficiency, and adapt to the needs of different scenarios (such as production line turnover, warehousing and transportation, loading and unloading, etc.).

[0003] In current metal parts conveying operations, trolleys are commonly used to transfer parts to the production line, and then workers manually move the parts to the processing station for operation. The overall height of the trolleys currently used is too low, which is not compatible with the working height of the operators. Workers need to bend over for a long time when picking up and placing parts. Long-term repetitive bending over can easily cause lumbar fatigue and strain, which not only affects the occupational health of the workers, but also reduces the efficiency of parts loading and unloading and the overall processing and production. Summary of the Invention

[0004] The purpose of this invention is to provide a metal parts transfer device with a special coating to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a metal parts transfer device with a special coating, comprising a mobile cart, with wheels at the bottom of the mobile cart and guide rails at the bottom of the wheels, a motor fixedly connected to the top of the mobile cart, a threaded rod fixedly connected to the output end of the motor, and telescopic plates fixedly connected to both sides of the mobile cart, and further comprising;

[0007] The lifting mechanism includes a placement plate, the bottom of which has a moving groove. A driven slider is slidably connected to the inner wall of the moving groove. During the sliding process of the moving slider, it drives the driven rod to move towards the placement plate, and the relative angles between the two ends of the moving slider and the moving vehicle and the placement plate change, thereby pushing the placement plate to lift upward.

[0008] The discharge mechanism includes a lifting rod, an lifting frame is fixedly connected to the end of the lifting rod, and a lifting plate is fixedly connected to the surface of the lifting frame. When the lifting rod moves upward, it drives the slider to slide upward along the inner wall of the groove plate, and at the same time drives the lifting frame to lift synchronously. The lifting frame further pushes the lifting plate to move upward along the inner wall of the placement hole, and the lifting plate lifts the parts in the placement hole upward.

[0009] The protective mechanism includes an isolation plate with an isolation cross plate fixedly connected to its surface. When the isolation plate moves upward, it causes the anti-fall plate to move synchronously. The anti-fall plate further pulls the anti-slip plate to slide upward along the inner wall of the slide rail. During the movement of the isolation plate, the rising plate simultaneously completes the lifting action of the components. After the isolation plate, the isolation cross plate and the rising plate are in place, the isolation plate and the isolation cross plate can separate and protect the lifted components.

[0010] Furthermore, the inner wall of the movable wheel contacts the surface of the guide rail, the end of the threaded rod away from the motor is rotatably connected to the end of the movable vehicle, the surface of the movable vehicle is provided with a sliding groove, and the number of telescopic plates is four, divided into two groups of two, with the four telescopic plates symmetrically arranged on both sides of the movable vehicle.

[0011] Furthermore, the lifting mechanism includes a crossbar, with movable blocks fixedly connected to both ends of the crossbar. A lifting rod is hinged to each movable block, and a driven rod is rotatably connected to the inner wall of the lifting rod. An inclined rod is fixedly connected to the inner wall of the slide groove, and an inclined rod is hinged to the surface of the driven slider. During the movement of the driven rod, it drives the driven slider to slide along the inner wall of the moving groove and the surface of the guide rod towards the motor side. Through the coordinated operation of the movable block, driven rod, and driven slider, the placement plate is smoothly lifted. The height of the placement plate can be flexibly adjusted according to the worker's height, avoiding workers bending over and improving the efficiency of parts production and processing.

[0012] Furthermore, the inner wall of the crossbar is threadedly connected to the surface of the threaded rod, the surface of the moving block is slidably connected to the inner wall of the slide groove, the inner walls of both the slide groove and the moving groove are fixedly connected to the end of the guide slide rod, the inner walls of both the lifting rod and the inclined rod are rotatably connected to the surface of the driven rod, the end of the inclined rod away from the driven slider is hinged to the surface of the moving vehicle, the end of the lifting rod away from the moving block is hinged to the bottom of the placement plate, the surface of the placement plate has a placement hole, the end of the telescopic plate away from the moving vehicle is fixedly connected to both sides of the placement plate, and the surface of the placement plate has an isolation hole.

[0013] Furthermore, the discharging mechanism includes a U-shaped rod, a curved plate fixedly connected to the surface of the U-shaped rod, a sliding plate fixedly connected to the end of the curved plate away from the U-shaped rod, a lifting rod hinged to the surface of the sliding plate, a U-shaped sliding plate fixedly connected to the surface of the telescopic plate, a grooved plate fixedly connected to the surface of the U-shaped sliding plate, and a slider slidably connected to the inner wall of the grooved plate. When the lifting rod moves upward, it drives the slider to slide upward along the inner wall of the grooved plate, and simultaneously drives the lifting frame to lift synchronously. The lifting frame further pushes the lifting plate to move upward along the inner wall of the placement hole, and the lifting plate lifts the parts in the placement hole upward, making it easy for workers to pick them up. This discharging mechanism can limit the placement of the parts to be transported in the placement hole to prevent the parts from falling during transportation. When it is necessary to pick up the parts, the lifting plate is used to lift the parts to facilitate convenient discharging, taking into account both transportation stability and ease of picking up the parts.

[0014] Furthermore, the two ends of the U-shaped rod are fixedly connected to the surface of the driven slider, the inner wall of the slide plate is slidably connected to the surface of the U-shaped slide plate, the end of the rising rod away from the rising frame is fixedly connected to the surface of the slider, the end of the lifting rod away from the slide plate is hinged to the surface of the rising rod, and the outer wall of the rising plate is in contact with the inner wall of the placement hole.

[0015] Furthermore, the protective mechanism includes a slide plate, the inner wall of which is slidably connected to an anti-slip plate. The top of the anti-slip plate is fixedly connected to an anti-fall plate, an isolation long plate, and an isolation cross plate, which can separate and protect the lifted parts, preventing them from colliding with each other during the process of workers picking up materials. At the same time, the anti-slip plate rises from both ends of the placement plate to further prevent the parts from falling, ensuring the safety of the parts picking and processing process in all aspects.

[0016] Furthermore, the surface of the slide plate is fixedly connected to both ends of the placement plate, the end of the anti-fall plate away from the anti-slip plate is fixedly connected to the top of the isolation long plate, both the isolation long plate and the isolation horizontal plate are in contact with the inner wall of the isolation hole, and the bottom of both the isolation long plate and the isolation horizontal plate are fixedly connected to the surface of the lifting frame.

[0017] The present invention has the following beneficial effects:

[0018] This invention employs a lifting mechanism. A motor drives a threaded rod to rotate, which in turn moves a crossbar towards the motor. As the crossbar moves, a moving block slides synchronously along the inner wall of the groove and the surface of the guide rod in the same direction. During this sliding motion, the driven rod moves towards the placement plate, and the relative angles between the two ends of the moving block and the moving carriage and placement plate change, thus lifting the placement plate upwards. The driven rod moves upwards synchronously, and as the placement plate moves upwards, it pulls the telescopic plate upwards. During the movement of the driven rod, the driven slider slides along the inner wall of the groove and the surface of the guide rod towards the motor. This effective linkage between the moving block, driven rod, and driven slider ensures smooth lifting of the placement plate. The height of the placement plate can be flexibly adjusted according to the worker's height, preventing workers from bending over and improving the efficiency of parts production.

[0019] This invention features a discharge mechanism where, as the driven slider slides, it drives a U-shaped rod to move towards the motor. The U-shaped rod further drives a bending plate to move synchronously. During the bending plate's movement, it pushes a sliding plate along the surface of the U-shaped sliding plate towards the motor. As the sliding plate slides, it drives one end of an upper lifting rod to move towards the motor, while the other end of the upper lifting rod pushes a rising rod upward. As the rising rod moves upward, it drives the slider to slide upward along the inner wall of the grooved plate, simultaneously lifting the rising frame synchronously. The rising frame further pushes the rising plate upward along the inner wall of the placement hole, lifting the parts in the placement hole upward for easy retrieval by workers. This discharge mechanism can confine the parts to be transported within the placement hole, preventing them from falling during transport. When retrieval is needed, the rising plate lifts the parts for convenient discharge, balancing transport stability and ease of retrieval.

[0020] This invention incorporates a protective mechanism. As the lifting frame moves outward, it simultaneously lifts the isolation long plate and the isolation horizontal plate upward. The upward movement of the isolation long plate causes the anti-fall plate to shift synchronously, further pulling the anti-fall plate upward along the inner wall of the slide rail. During the movement of the isolation long plate, the lifting plate simultaneously lifts the components. Once the isolation long plate, isolation horizontal plate, and lifting plate are in place, the isolation long plate and isolation horizontal plate can separate and protect the lifted components, preventing collisions during material handling. Simultaneously, the anti-fall plate rises from both ends of the placement plate, further preventing components from falling, thus comprehensively ensuring the safety of component handling and processing.

[0040] The lifting mechanism 10 includes a crossbar 11, with moving blocks 12 fixedly connected to both ends of the crossbar 11. A lifting rod 13 is hinged to the moving blocks 12, and a driven rod 15 is rotatably connected to the inner wall of the lifting rod 13. An inclined rod 19 is fixedly connected to the inner wall of the slide groove, and the inclined rod 19 is hinged to the surface of the driven slider 17. The relative angles between the two ends of the moving blocks 12 and the moving cart 1 and the placement plate 14 change, thereby pushing the placement plate 14 upward. The driven rod 15 moves upward synchronously. When the placement plate 14 moves upward, it pulls the telescopic plate 6 to extend upward synchronously. During the movement of the driven rod 15, it drives the driven slider 17 to slide along the inner wall of the moving groove 16 and the surface of the guide slide rod 18 toward the motor 4. Through the linkage of the moving blocks 12, the driven rod 15 and the driven slider 17, the placement plate 14 is lifted smoothly. The height of the placement plate 14 can be flexibly adjusted according to the height of the worker, avoiding the worker bending over and improving the efficiency of parts production and processing.

[0041] The inner wall of the crossbar 11 is threadedly connected to the surface of the threaded rod 5. The surface of the moving block 12 is slidably connected to the inner wall of the chute.

[0043] Both ends of the U-shaped rod 31 are fixedly connected to the surface of the driven slider 17. The inner wall of the slide plate 33 is slidably connected to the surface of the U-shaped slide plate 38. The end of the lifting rod 35 away from the lifting frame 36 is fixedly connected to the surface of the slider 40. The end of the lifting rod 34 away from the slide plate 33 is hinged to the surface of the lifting rod 35. The outer wall of the lifting plate 37 contacts the inner wall of the placement hole. The lifting frame 36 further pushes the lifting plate 37 to move upward along the inner wall of the placement hole. The lifting plate 37 lifts the parts in the placement hole upward, making it easy for workers to pick them up. This discharge mechanism can limit the parts to be transported and place them in the placement hole to prevent the parts from falling during transportation. When it is necessary to pick up the parts, the lifting plate 37 is used to lift the parts to facilitate convenient discharge, taking into account both transportation stability and convenient material retrieval.

[0044] The protective mechanism 50 includes a slide plate 51. As the lifting frame 36 moves outward, it simultaneously pushes the isolation long plate 54 and the isolation horizontal plate 55 upward. When the isolation long plate 54 moves upward, it drives the anti-fall plate 53 to move synchronously. The anti-fall plate 53 further pulls the anti-slip plate 52 to slide upward along the inner wall of the slide plate 51. The anti-slip plate 52 is slidably connected to the inner wall of the slide plate 51, and the anti-fall plate 53 is fixedly connected to the top of the anti-fall plate 52. During the movement of the isolation long plate 54, the lifting plate 37 simultaneously completes the lifting action of the parts. After the isolation long plate 54, the isolation horizontal plate 55 and the lifting plate 37 are in place, the isolation long plate 54 and the isolation horizontal plate 55 can separate and protect the lifted parts, preventing the parts from colliding with each other during the workers' material handling process. At the same time, the anti-slip plate 52 rises from both ends of the placement plate 14 to further prevent the parts from falling, ensuring the safety of the parts handling and processing process in all aspects.

[0045] The surface of the slide plate 51 is fixedly connected to both ends of the placement plate 14. The end of the anti-fall plate 53 away from the anti-slip plate 52 is fixedly connected to the top of the isolation long plate 54. Both the isolation long plate 54 and the isolation horizontal plate 55 are in contact with the inner wall of the isolation hole. The bottom of both the isolation long plate 54 and the isolation horizontal plate 55 are fixedly connected to the surface of the rising frame 36.

[0046] In use, the starter motor 4 drives the threaded rod 5 to rotate. During the rotation of the threaded rod 5, the crossbar 11 moves in the direction of the motor 4. When the crossbar 11 moves, it drives the moving block 12 to slide synchronously along the inner wall of the slide groove and the surface of the guide slide rod 18 in the direction of the crossbar 11. During the sliding process of the moving block 12, it drives the driven rod 15 to move in the direction of the placement plate 14, and the relative angles between the two ends of the moving block 12 and the moving carriage 1 and the placement plate 14 change, thereby pushing the placement plate 14 upward. The driven rod 15 moves upward synchronously, and the placement plate 14 rises upward. During movement, the telescopic plate 6 extends upwards synchronously. As the driven rod 15 moves, it drives the driven slider 17 to slide along the inner wall of the moving groove 16 and the surface of the guide rod 18 towards the motor 4. Through the coordinated action of the moving block 12, the driven rod 15, and the driven slider 17, the placement plate 14 is smoothly lifted. The height of the placement plate 14 can be flexibly adjusted according to the worker's height, avoiding the worker's bending over and improving the efficiency of parts production. While the driven slider 17 slides, it drives the U-shaped rod 31 to move towards the motor 4. The U-shaped rod 31 further drives the curved plate 32 to move synchronously. During the movement of the curved plate 32, it pushes the slide plate 33 to slide along the surface of the U-shaped slide plate 38 towards the motor 4. When the slide plate 33 slides, it drives one end of the lifting rod 34 to move towards the motor 4, while the other end of the lifting rod 34 pushes the rising rod 35 upward. When the rising rod 35 moves upward, it drives the slider 40 to slide upward along the inner wall of the groove plate 39, and at the same time drives the rising frame 36 to rise synchronously. The rising frame 36 further pushes the rising plate 37 to move upward along the inner wall of the placement hole, and the rising plate 37 releases the object. The parts inside the placement hole are lifted upwards for easy access by workers. This discharge mechanism can limit the placement of parts to be transported within the placement hole to prevent them from falling during transportation. When retrieval is needed, the lifting plate 37 lifts the parts for convenient discharge, balancing transportation stability and ease of retrieval. As the lifting frame 36 moves outwards, it simultaneously pushes the isolation plate 54 and the isolation horizontal plate 55 upwards. When the isolation plate 54 moves upwards, it drives the anti-fall plate 53 to move synchronously. The anti-fall plate 53 further pulls the anti-slip plate 52 to slide upwards along the inner wall of the slide plate 51. During the movement of the isolation plate 54, the lifting plate 37 simultaneously completes the lifting action of the parts. After the isolation plate 54, the isolation horizontal plate 55, and the lifting plate 37 are in place, the isolation plate 54 and the isolation horizontal plate 55 can separate and protect the lifted parts, preventing them from colliding with each other during worker retrieval. At the same time, the anti-slip plate 52 rises from both ends of the placement plate 14 to further prevent parts from falling, ensuring the safety of parts retrieval and processing in all aspects.
