Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation equipment, in particular to a double-stroke material taking mechanism with dust blowing function. BACKGROUND

[0002] The double-stroke material taking mechanism is a high-efficiency and multi-step automated material taking device that completes the material taking task through sequential actions in two stages. The first stage is usually rapid descent or approach, and the second stage is precise grabbing or placing. Such mechanisms are widely used in electronic assembly, precision part processing, food and drug packaging, etc. The core advantage is that it can balance work efficiency and positioning accuracy, and through the decomposition of the stroke, it optimizes power configuration and structural design, adapting to complex, clean or strictly required process sequence application scenarios.

[0003] However, in the material handling assembly line environment, the material surface is prone to adsorbing dust. The traditional material taking mechanism has a single function, and the cleaning process is usually set independently, which is time-consuming and inconvenient to use, and it is difficult to achieve efficient cooperation of material taking and immediate cleaning. Therefore, a double-stroke material taking mechanism is proposed to solve the above problems. SUMMARY

[0004] The purpose of the present application is to overcome the shortcomings of the prior art and provide a double-stroke material taking mechanism with dust blowing function, which can effectively solve the above problems.

[0005] To achieve the above requirements, the technical solution adopted by the present application to solve its technical problems is: A double-stroke material taking mechanism with dust blowing function is provided, which includes a mounting frame, a first mounting plate vertically downwardly provided on the mounting frame, two first lifting arms oppositely provided on the side walls of the first mounting plate, and two second lifting arms respectively provided on the two first lifting arms; a fixed plate is horizontally provided on the mounting frame and below the first mounting plate; a rotating shaft is vertically provided through the fixed plate, the rotating shaft is fixedly and rotatably provided on the fixed plate, and the rotating shaft is between the two first lifting arms; a guide rail in the form of a screw thread is coaxially provided on the side wall of the upper end of the rotating shaft, and a driving block adapted to the guide rail is provided on the side wall of the first lifting arm facing the rotating shaft; at least one fan blade is radially provided on the lower end of the rotating shaft.

[0006] The double-stroke material taking mechanism with dust blowing function includes a first lifting arm having a first longitudinal end arranged vertically and a first transverse end arranged horizontally towards the other lifting arm; the driving block is arranged on the side wall of the first transverse end away from the first longitudinal end; and a driving device for driving the first lifting arm is further arranged on the side wall of the first mounting plate.

[0015] The application discloses a double-stroke material taking mechanism with a dust blowing function. The application realizes mechanical linkage and synchronous control of double-stroke material taking and dust blowing actions through the setting of the threaded guide rail, the fan blade and the driving block on the rotating shaft. In the process of the first lifting arm descending to take material, the driving block is driven to move along the guide rail, the rotating shaft is driven to rotate, the fan blade at the lower end of the rotating shaft rotates synchronously, and directional airflow is generated to blow dust on the surface of the material immediately before and after taking the material. This integrated design eliminates the need for independent cleaning stations or external air supply devices, greatly shortens the operation cycle, and significantly improves the efficiency and automation level of the coordinated operation of material taking and cleaning.

[0016] The lifting of the first lifting arm not only participates in the material taking stroke, but also drives the rotating shaft to rotate to realize dust blowing during the descending process. This structure not only ensures the reliability of fast approach and precise positioning, but also forms a continuous and uniform blowing airflow through the rotation of the fan blade, effectively removing the adsorbed dust on the surface of the material. The overall structure is simple, the power configuration is optimized, and complex air paths or electrical controls are not required, which reduces equipment costs and maintenance difficulty, and is especially suitable for automated production lines with high cleanliness requirements and tight processes, enhancing the practicality and environmental adaptability of the mechanism.

Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the protection scope of the present application.

[0025] A double-stroke material taking mechanism with dust blowing function according to a preferred embodiment of the present application, as shown in Figures 1-3As shown, it comprises a mounting frame 1, a first mounting plate 10 vertically downwardly provided on the mounting frame 1, two first lifting arms 2 oppositely provided on the two side walls of the first mounting plate 10, and two second lifting arms 3 respectively provided on the two first lifting arms 2; a fixed plate 11 is horizontally provided on the mounting frame 1, and the fixed plate 11 is provided below the first mounting plate 10; a rotating shaft 4 is vertically and penetratively provided on the fixed plate 11, and the rotating shaft 4 is fixedly and rotatably provided on the fixed plate 11, and the rotating shaft 4 is provided between the two first lifting arms 2; a thread-shaped guide rail 41 is coaxially provided on the circumferential wall of the upper end of the rotating shaft 4, and a driving block 22 adapted to the guide rail 41 is provided on the side wall of the first lifting arm 2 facing the rotating shaft 4; at least one fan blade 40 is radially provided on the lower end of the rotating shaft 4.

[0026] In the embodiment, the first lifting arm 2 has a first longitudinal end 20 vertically provided, and a first transverse end 21 horizontally provided towards the other lifting arm; the driving block 22 is provided on the side wall of the first transverse end 21 away from the first longitudinal end 20; wherein the L-shaped first lifting arm 2 realizes the partition of the lifting and taking functions and the function of driving the rotating shaft 4 to rotate, the first longitudinal end 20 is responsible for the lifting stroke of taking, and the first transverse end 21 is dedicated to driving the rotating shaft 4. The side wall of the first mounting plate 10 is further provided with a driving device for driving the first lifting arm 2. The driving device ensures the lifting of the first lifting arm 2, and improves the certainty and starting efficiency of the mechanism action.

[0027] In the embodiment, the driving device comprises a first sliding rail 12 fixedly provided on the side wall of the first mounting plate 10, and a first sliding block (not marked in the figure) vertically and slidingly provided on the side of the first sliding rail 12 away from the first mounting plate 10; the first sliding block is fixedly connected with the first longitudinal end 20; the cooperation of the first sliding rail 12 and the first sliding block constitutes the main guide structure of the first lifting arm 2, and ensures the straightness precision and stability of the lifting movement thereof. A plurality of guide columns 13 are slidingly provided on the first sliding rail 12 in the vertical direction, and the lower ends of the guide columns 13 are fixedly provided on the upper surface of the first transverse end 21. The plurality of guide columns 13 added not only can guide the lifting of the first lifting arm 2, but also further enhance the anti-torsion and anti-overturning ability of the first transverse end 21, especially when it bears the lateral force driven by the rotating shaft 4, can effectively prevent jamming, ensure the smooth engagement of the driving block 22 and the thread guide rail 41, and improve the overall stability of the double-stroke movement.

[0028] In the embodiment, the side wall of the first transverse end 21 opposite to the rotating shaft 4 is recessed with a recess 23 adapted to the external contour of the rotating shaft 4. The recess 23 is designed to enable the first lifting arm 2 to partially cover the rotating shaft 4, significantly reducing the horizontal space occupied by the mechanism, and realizing a more compact layout; at the same time, the recess 23 guides the rotation of the rotating shaft 4, and improves the operation safety.

[0029] In the embodiment, the second mounting plate 14 is vertically arranged on the side wall of the first lifting arm 2 away from the other lifting arm, and the second lifting arm 3 is arranged on the side of the second mounting plate 14 away from the first lifting arm 2. The second mounting plate 14 is further provided with the second sliding rail 15 for driving the second lifting arm 3 to lift. The second lifting arm 3 is driven by the second sliding rail 15 arranged on the first lifting arm 2 independently, so that the fine material taking action in the second stage can be decoupled from the rapid lifting action in the first stage, and the control is realized, and the precise motion freedom is provided for the material taking of the suction cup 5.

[0030] Specifically, the second mounting plate 14 is arranged on the first longitudinal end 20 of the first lifting arm 2.

[0031] In the embodiment, the second lifting arm 3 is in L shape, and the second sliding block 16 is longitudinally and slidingly arranged on the second sliding rail 15, and the second sliding block 16 is fixedly connected with the second longitudinal end 30 of the second lifting arm 3. The second transverse end 31 of the second sliding block 16 is arranged at the lower end of the second longitudinal end 30 and horizontally arranged away from the second sliding rail 15. The L-shaped second lifting arm 3 horizontally arranges the second transverse end 31, which reduces the gravity during material taking and improves the motion stability.

[0032] In the embodiment, the lower surface of the second transverse end 31 is provided with the suction cup 5 for taking the material. The suction cup 5 is arranged at the end of the second lifting arm 3 to directly perform the material taking and placing operation. The core beneficial effect is that the dust blowing function is formed in the process cooperation: in the process that the suction cup 5 approaches the surface of the material, the airflow generated by the fan blade 40 driven by the rotating shaft 4 can blow away the dust on the surface of the material in advance or synchronously, which greatly reduces the problem of insufficient suction force or displacement caused by dust, significantly improves the success rate and reliability of material taking, and realizes the efficient process of cleaning first and then grabbing.

[0033] In the embodiment, the fixed plate 11 is provided with the mounting hole 110 matched with the diameter of the rotating shaft 4, the inner wall of the mounting hole 110 is provided with the fixed block 111, the side wall of the rotating shaft 4 is coaxially provided with the fixed groove 42, and the fixed block 111 is slidingly arranged in the fixed groove 42 along the circumferential direction of the rotating shaft 4. The fixed block 111 and the fixed groove 42 form an efficient axial positioning and radial rotating support structure. The fixed block 111 is clamped into the fixed groove 42 of the rotating shaft 4, which can strictly limit the displacement of the rotating shaft 4 in the vertical direction, ensure the axial position of the rotating shaft 4, and ensure the constant engagement position of the threaded guide rail 41 and the driving block 22. At the same time, the fixed block 111 allows the rotating shaft 4 to smoothly rotate in the fixed groove 42, realizes the fixed shaft rotation, and provides a stable and low-friction rotating fulcrum for the threaded driving and the rotation of the fan blade 40.

[0034] Preferably, the upper and lower ends of the fixed block 111 are vertically provided with the rollers 112, which convert the friction between the fixed block 111 and the rotating shaft 4 into rolling friction, and improve the smoothness of the rotating shaft 4.

[0035] In this embodiment, the first lifting arm 2, the second lifting arm 3, the rotating shaft 4, the second mounting plate 14 and the driving device jointly constitute a material taking assembly 6, and the material taking assembly 6 is provided on the first mounting plate 10 in two and opposite positions; the two material taking assemblies 6 are located in the same horizontal plane. The structure of the symmetrically arranged double material taking assemblies 6 is the key to realize high efficiency of the mechanism. The two material taking assemblies 6 can work independently or synchronously, and process the materials of two workstations at the same time, so that the work efficiency is doubled; the symmetric layout is beneficial to balance the moment generated when the mechanism moves, reduces the unbalanced load impact on the mounting frame 1, and runs more smoothly; in addition, the double assembly design provides flexibility for the layout of the production line, which can adapt to various production rhythm requirements such as parallel or alternating operation.

[0036] In this embodiment, the mounting frame 1 is inverted U-shaped, the first mounting plate 10 is fixedly connected with the third transverse end 17 of the mounting frame 1, the two ends of the fixed plate 11 are respectively fixedly connected with the two third longitudinal ends of the mounting frame 1, and the two rotating shafts 4 are arranged on the fixed plate 11; the inverted U-shaped mounting frame 1 provides a high-rigidity mounting base for the double-stroke material taking mechanism, effectively resists the working load, and ensures the precision stability of long-period operation. The lower end of the fixed plate 11 is provided with a third mounting plate 19 through a connecting rod 191, the third mounting plate 19 is provided with a through hole 190 penetrating longitudinally, and the fan blade 40 is arranged in the through hole 190. The third mounting plate 19 and the through hole 190 form an airflow guiding channel. The through hole 190 restricts the airflow direction generated when the fan blade 40 rotates, so that the airflow is more concentrated and directional to blow to the lower material area, reduces the airflow diffusion, and improves the dust blowing efficiency; at the same time, the third mounting plate 19 also provides additional protection and positioning for the fan blade 40, and enhances the structural integrity of the lower part of the mechanism.
