Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of feeding mechanism, and particularly relates to a feeding method and a feeding device for inclined feeding and orderly separation. BACKGROUND

[0002] In the field of automatic production, the feeding link plays a key role in efficient and accurate assembly of products. As a commonly used auxiliary feeding method, the vibrating disc feeding is widely used in various production lines. It can arrange a plurality of materials in an orderly manner to a certain extent, and provide a material basis for subsequent automatic assembly equipment, thereby assisting the smooth assembly of various parts of products into complete products.

[0003] However, with the rapid development of science and technology, ultra-thin materials (such as materials with a thickness of less than 0.3 mm) are increasingly frequently applied in many high-end industries, and the requirements for feeding of the ultra-thin materials are increasingly stringent. The existing vibrating disc feeding technology exposes many problems when facing the ultra-thin materials.

[0004] Firstly, the ultra-thin materials are light and thin in texture and strong in flexibility, and are prone to stacking in the traditional feeding process, which not only hinders the normal feeding process, but also may cause material jamming failure of subsequent processing equipment, and seriously affects the continuity of production.

[0005] Secondly, the in-place detection of the ultra-thin materials becomes a thorny problem. On the one hand, the conventional detection methods based on physical contact or simple sensing are difficult to accurately capture the slight position changes of the light and thin materials; on the other hand, due to the material properties, the sensitivity of the materials to the detection environment is high, and slight external interference may cause detection errors, so that it is impossible to accurately judge whether the materials have been accurately sent to the specified position, and thus the product assembly precision is affected.

[0006] Thirdly, the feeding efficiency needs to be improved. Due to the frequent jamming of the materials and the delay of the detection link, the overall feeding speed is greatly reduced when the existing feeding method is used to process the ultra-thin materials, and it is difficult to meet the demand for rapid flow of materials in large-scale and continuous production operations.

[0007] Therefore, in the present application, a feeding method and a feeding device for inclined feeding and orderly separation are provided to overcome the above-mentioned defects. SUMMARY

[0008] A first object of the present application is to provide a feeding method for inclined feeding and orderly separation. The feeding method is combined with a straight vibration vacuum system and a receiving vacuum system, so that the transfer process of the materials from the inclined straight vibration track to the separation seat is more efficient. In addition, when the materials are transferred, the receiving vacuum system of the receiving unit sucks the materials at the critical position of the inclined straight vibration track into the separation seat. After the materials are completely sucked in, the air flow channel is blocked, and the dynamic change of the connected flow meter is used as a key to judge the in-place of the materials, so as to accurately control the transfer of the materials and improve the processing accuracy.

[0009] The application adopts the following technical scheme: a feeding method for inclined feeding and orderly separation, comprising the following steps:

[0010] S01: the material in the storage device is vibrated by the circular vibration feeding unit and fed to the bottom of the spiral feeding track in the circular vibration feeding unit, the material is orderly arranged by climbing the spiral feeding track and gradually arranging the material, and enters the inclined straight vibration track provided by the inclined straight vibration track unit;

[0011] S02: the inclined straight vibration track unit drives the material to move in a predetermined direction along the inclined straight vibration track and pushes the material away from the circular vibration feeding unit;

[0012] S03: when the material is pushed to the critical position at the front end of the inclined straight vibration track, the straight vibration vacuum system of the inclined straight vibration track unit is started to adsorb the material at the critical position of the inclined straight vibration track;

[0013] S04: the separation seat in the receiving unit is driven to rotate until the separation seat is flush with the inclined surface of the inclined straight vibration track carrying the material, the straight vibration vacuum system is closed, at the same time, the receiving vacuum system of the receiving unit is started to suck the material at the critical position of the inclined straight vibration track into the separation seat, when the material is completely sucked into the separation seat, the airflow channel of the internal vacuum system of the separation seat is blocked, at this moment, the flow meter connected with the pipeline of the internal vacuum system of the separation seat shows a dynamic change, based on this, it is judged that the material on the separation seat is in place, and then the straight vibration vacuum system is started again;

[0014] S05: the separation seat in the receiving unit is driven to rotate to the horizontal position again, the receiving vacuum system is closed, and the material is taken away; if the vacuum value monitored by the flow meter is consistent with the characteristic value recorded when the material blocks the internal vacuum system of the separation seat, it indicates that the material has not been sucked away; at this moment, the separation seat in the receiving unit is driven to rotate to the preset position, and the back flushing program is started to completely blow away the residual material on the separation seat;

[0015] S06: after cleaning, the separation seat is continuously rotated to be flush with the inclined surface of the inclined straight vibration track carrying the material, and the above operations are repeatedly executed.

[0016] Further, in step S04, when the material is completely sucked into the separation seat, the separation seat is photographed by the camera detection unit, and whether the material on the separation seat is in place is judged again; if the material on the separation seat is in place, the straight vibration vacuum system is started again, and the subsequent steps S05 and S06 are continued.

[0017] Further, in step S06, the rotation of the separation seat is continuously driven to the state of being flush with the inclined surface of the inclined straight vibration track carrying the material, and then the camera detection unit takes a picture of the separation seat again for re-inspection to determine whether the material on the separation seat is taken away; if the material is not taken away, the separation seat in the rotary material receiving unit is rotated to a preset position, a back blowing program is started to completely blow away the residual material on the separation seat, and then step S06 is continuously executed.

[0018] Further, when the camera detection unit takes a picture of the separation seat, the light reflected by the material is refracted by the prism at the position of the light source and then propagates to the position of the lens.

[0019] Compared with the prior art, the present application has the following advantages:

[0020] In the feeding method for orderly separation of inclined feeding, in step S01, the material passes through the climbing process of the spiral feeding track, and the physical form of the track is used to arrange the disordered material to be uniformly oriented. The orderly arrangement of the material is beneficial to reduce the blocking and collision of the material during conveying, and ensures the stability and continuity of the feeding process, and improves the overall production efficiency. Then, the inclined straight vibration track unit can push the material with stable and orderly pushing force, ensuring that the material can advance according to the predetermined speed and direction, and the material accumulation or uneven conveying speed does not occur.

[0021] At the same time, through the cooperation of the straight vibration vacuum system and the material receiving vacuum system, the transfer process of the material from the inclined straight vibration track to the separation seat is more efficient. The straight vibration vacuum system is opened when the material reaches the critical position at the front end of the inclined straight vibration track, creating a vacuum adsorption environment; when the material is sucked into the separation seat by the material receiving vacuum system and the material is confirmed to be in place by the flow meter, the straight vibration vacuum system is opened again to further assist the stable placement of the material in the separation seat, and also prepares for the next material transfer. This close cooperation reduces the stagnation time during the material transfer process, improves the overall feeding efficiency, and is especially suitable for large-scale and continuous production operations.

[0022] In addition, during the material transfer process, the material receiving vacuum system of the material receiving unit is responsible for sucking the material at the critical position of the inclined straight vibration track into the separation seat. When the material is completely sucked into the separation seat, the material blocks the airflow channel of the internal vacuum system of the separation seat, at which time the flow meter connected to the pipeline of the internal vacuum system of the separation seat shows a dynamic change, which becomes the key signal for judging whether the material is accurately positioned. The flow meter can accurately judge whether the material is positioned by detecting the air pressure condition of the path connected to the pipeline of the internal vacuum system of the separation seat in a non-contact manner. For some materials with fragile texture and easy to be damaged (such as ultra-thin materials, precision film materials, etc.), the traditional contact detection may cause material scratching and collision damage, which ensures the integrity of the material during the transfer process. Through this accurate monitoring, the amount and position of each material transfer can be accurately controlled, avoiding the omission or excessive suction of the material, improving the accuracy and consistency of the material processing, and effectively solving the problem that ultra-thin materials and the like are difficult to be accurately detected to the position by conventional means. At the same time, during the entire feeding process, the flow meter continuously detects the air pressure condition, which is equivalent to real-time monitoring of the material transfer process. Once abnormal air pressure fluctuation is found, it may indicate that the material transfer has a problem, such as material blockage, vacuum system leakage, etc. The system can quickly make adjustments according to the feedback information of the flow meter to avoid further deterioration of the problem and ensure the stability and continuity of the feeding process.

[0024] a storage device for storing materials;

[0025] a circular vibration feeding unit arranged on one side of the storage device and having a spiral feeding track;

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application. Figure 1 to the drawings Figure 5 and specific embodiments, the present application is described in detail:

[0049] The present application provides a feeding method for inclined feeding and orderly separation, which is especially suitable for feeding operation of ultra-thin materials, and includes the following steps:

[0050] S01: In the starting stage, the material in the storage device 1 is vibrated by the circular vibration feeding unit 2 to the bottom of the spiral feeding track 20 in the circular vibration feeding unit 2. Under the continuous vibration, the material climbs along the spiral structure of the spiral feeding track 20 in disorder, and is gradually arranged in order and uniformly oriented in the climbing process, and then smoothly connects the inclined straight vibration track 30 arranged in the inclined straight vibration track unit 3, so as to realize preliminary guidance and arrangement.

[0051] S02: The inclined straight vibration track unit 3 drives the material to be pushed away from the circular vibration feeding unit 2 along the given direction of the inclined straight vibration track 30 by the stable and orderly pushing force of the vibration system of the inclined straight vibration track unit 3.

[0052] S03: When the material continuously advances on the inclined straight vibration track 30 until it reaches the critical position at the front end, the straight vibration vacuum system integrated in the inclined straight vibration track unit 3 responds quickly and opens immediately to create a vacuum adsorption environment, adsorbing the material at the critical position of the inclined straight vibration track 30 and preparing for the transfer of the material to the receiving unit 4.

[0053] S04: The separation seat 40 in the receiving unit 4 is driven to rotate until it is flush with the inclined surface of the inclined straight vibration track 30 carrying the material, achieving a docking state. At the same time, the straight vibration vacuum system is closed. At the same time, the receiving vacuum system of the receiving unit 4 is activated and opened instantly, and under the action of the vacuum suction force, the material at the critical position of the inclined straight vibration track 30 is quickly and accurately sucked into the separation seat 40.

[0054] When the material is completely sucked into the separation seat 40, the material blocks the air flow channel of the internal vacuum system of the separation seat. At this moment, the flow meter connected to the internal vacuum system of the separation seat changes dynamically, based on which it is determined that the material in the separation seat is in place, and the straight vibration vacuum system is opened again to adsorb and fix the material at the critical position of the inclined straight vibration track 30 to prevent material stacking.

[0055] S05: The separation seat 40 in the receiving unit 4 is driven to rotate to the horizontal position again, the receiving vacuum system is closed, and the material is placed in the separation seat 40, waiting to be taken away; if the material is taken away, the internal vacuum system of the separation seat 40 is connected to the outside; otherwise, if the vacuum reading monitored by the flow meter and the characteristic value recorded when the material blocks the internal vacuum system of the separation seat 40 are consistent, it indicates that the material has not been sucked away. At this time, the separation seat 40 in the receiving unit 4 is driven to rotate to the preset position, and the backflushing program is started to completely blow away the residual material on the separation seat 40. In this embodiment, high-pressure gas flow is used to completely blow away the residual material on the separation seat 40. It should be noted that the way in which the material is taken away in the present application is not limited, and can be designed and selected by those skilled in the art according to the actual situation, such as in this embodiment, the material is adsorbed and taken away by the horizontal suction nozzle 60 at the turret 6.

[0056] S06: After cleaning, continue to drive the separation seat 40 to rotate to the state of being flush with the inclined surface of the inclined straight vibration track 30 carrying the material, and repeat the above series of operations to realize a continuous, efficient and precise inclined feeding and orderly separation feeding process.

[0057] The feeding method for the inclined feeding and orderly separation in the application, in the S01 step, the material is arranged in a unified direction by the physical form of the spiral feeding track 20 through the climbing process of the spiral feeding track 20, and the orderly arrangement of the material is conducive to reducing the blockage and collision of the material in the conveying process, ensuring the stability and continuity of the feeding process and improving the overall production efficiency. Then, the inclined straight vibration track unit 3 can stably and orderly push the material, ensuring that the material can advance at a predetermined speed and direction and avoiding the accumulation or uneven conveying speed of the material.

[0058] Meanwhile, through the cooperation of the straight vibration vacuum system and the receiving vacuum system, the transfer process of the material from the inclined straight vibration track 30 to the separation seat 40 is more efficient. The straight vibration vacuum system is opened when the material reaches the critical position at the front end of the inclined straight vibration track 30, creating a vacuum adsorption environment; when the receiving vacuum system sucks the material into the separation seat 40 and confirms the material in place through the flow meter, the straight vibration vacuum system is opened again, further assisting the stable placement of the material in the separation seat 40 and preparing for the next material transfer. This close cooperation reduces the stagnation time during the material transfer process, improves the overall feeding efficiency, and is especially suitable for large-scale and continuous production operations.

[0059] In addition, during the material transfer process, the receiving vacuum system of the receiving unit 4 is responsible for sucking the material at the critical position of the inclined straight vibration track 30 into the separation seat 40. When the material is completely sucked into the separation seat 40, the material blocks the airflow channel of the internal vacuum system of the separation seat, and at this time, the measured value of the flow meter connected to the pipeline of the internal vacuum system of the separation seat changes dynamically, which is the key signal for judging whether the material is accurately in place. The flow meter can accurately judge whether the material is in place in a non-contact manner by detecting the air pressure condition of the path connected to the pipeline of the internal vacuum system of the separation seat. For some materials with fragile texture and easy to be damaged (such as ultra-thin materials, precision film materials, etc.), the traditional contact detection may cause material scratching and collision damage, ensuring the integrity of the material during the transfer process. Through this accurate monitoring, the amount and position of each material transfer can be accurately controlled, avoiding the omission or excessive suction of the material, improving the accuracy and consistency of the material processing, and effectively solving the problem of accurately detecting the position of ultra-thin materials and other materials that are difficult to detect by conventional means. At the same time, during the entire feeding process, the flow meter continuously detects the air pressure condition, which is equivalent to real-time monitoring of the material transfer process. Once abnormal air pressure fluctuation is found, it may indicate that the material transfer has a problem, such as material blockage or vacuum system leakage. The system can make rapid adjustments according to the feedback information of the flow meter to avoid further deterioration of the problem, ensuring the stability and continuity of the feeding process.

[0060] In summary, the feeding method in the application solves the problems of easy stacking of ultra-thin material, inaccurate in-place detection, and low feeding efficiency.

[0061] Further, in step S04, when the material is completely sucked into the separation seat 40, the separation seat 40 is photographed by the camera detection unit 5, and it is judged again whether the material on the separation seat 40 is in place. If the material on the separation seat 40 is in place, the vacuum system is opened again, and the subsequent steps S05 and S06 are continued.

[0062] In step S04, the material is preliminarily judged to be in place by detecting the material blocking the vacuum system inside the separation seat 40 by the flow meter, and then the separation seat 40 is photographed by the camera detection unit 5 for secondary judgment. This double detection mechanism greatly improves the accuracy of judging whether the material is accurately in place. The flow meter detection is mainly based on the physical properties of the vacuum system, while the camera detection is directly confirmed from the visual angle, which makes up for the shortcomings of single detection method and enhances the detection ability of the whole system for different materials.

[0063] In addition, the photos taken by the camera detection unit 5 can be used as a record of the material in place state. When the product has quality problems, these photos can be used to trace back to the initial state of the material in the separation seat 40, and analyze whether the quality problem is caused by inaccurate material in place.

[0064] More specifically, in step S06, after the separation seat 40 is driven to rotate to the state of being flush with the inclined surface of the inclined direct vibration track 30 carrying the material, the separation seat 40 is photographed again by the camera detection unit 5 for re-inspection to judge whether the material on the separation seat 40 is taken away. If the material is not taken away, the separation seat 40 in the rotary material receiving unit 4 is rotated to the preset position, the back blowing program is started to completely blow away the residual material on the separation seat 40, and then the step S06 process is continued.

[0065] The re-inspection link of the camera detection unit in step S06 can visually confirm again whether the material on the separation seat is taken away. Compared with the detection method relying solely on the vacuum system, the camera photographing re-inspection provides more direct and accurate material state information, avoids the subsequent production errors caused by misjudgment, reduces the number of production interruptions caused by residual material, and improves the stability and continuity of the production process. This is particularly important for large-scale and automated production lines, which can significantly improve production efficiency and product quality stability.

[0066] Further, when the camera detection unit 5 takes a picture of the separation seat, the light reflected by the material is refracted by the prism at the position of the light source, and then propagates to the position of the lens according to a specific optical path, thereby realizing the optical imaging process of the material. By refracting the light through the prism, the light entering the lens can be effectively controlled and optimized. The prism can adjust the propagation direction and angle of the light, so that the light reflected by the material enters the lens more uniformly, which helps to reduce the imaging shadows or bright spots caused by uneven light, thereby improving the clarity and contrast of the imaging.

[0067] The present application also provides a feeding device based on the above-mentioned feeding method for orderly separation of inclined feeding, as shown in the figure, which comprises: Figures 1 to 5

[0068] a storage device 1 for containing materials;

[0069] a circular vibration feeding unit 2 arranged on one side of the storage device 1 and having a spiral feeding track 20;

[0070] an inclined straight vibration track unit 3 arranged at the discharge end of the circular vibration feeding unit 2, having an inclined straight vibration track 30 connected with the discharge port of the spiral feeding track 20, and a straight vibration vacuum system for adsorbing and fixing the materials;

[0071] a receiving unit 4 arranged at the discharge end of the inclined straight vibration track unit 3 and having a receiving vacuum system for transferring the adsorbed materials; and through the cooperation of the receiving unit 4 and the inclined straight vibration track unit 3, the materials are transferred;

[0072] a visual detection unit 5 arranged above the receiving unit 4 for taking a picture of the separation seat 40 in the receiving unit 4 and detecting whether there is material on the separation seat 40, etc.

[0073] In operation, the materials in the storage device 1 are vibrated by the circular vibration feeding unit 2 to the bottom of the spiral feeding track 20 in the circular vibration feeding unit 2, and the circular vibration feeding unit 2 vibrates to make the materials climb up the spiral feeding track 20 from the bottom in disorder. In this process, the materials are gradually arranged in order and uniformly oriented by the restriction of the spiral structure, and then smoothly enter the inclined straight vibration track 30 of the inclined straight vibration track unit 3. The inclined straight vibration track unit 3 uses its vibration system to push the materials away from the circular vibration feeding unit 2 with stable propulsion. As the materials continuously advance on the inclined straight vibration track 30, they are transferred by the receiving unit 4 when they reach the critical position at the front end. At the same time, the visual detection unit 5 is used to realize precise feeding.

[0074] ​The feeding device in the application realizes the arrangement and stable conveying of materials from disorder to order through the combination of the spiral feeding track 20 of the circular vibration feeding unit 2 and the inclined straight vibration track 30 of the inclined straight vibration track unit 3. During the climbing and straight pushing of the materials, the materials can maintain stable speed and arrangement mode, which provides reliable material flow for subsequent accurate material receiving and processing. The close cooperation between the units of the whole feeding device forms a stable feeding system, reducing the risk of production interruption caused by poor material conveying and inaccurate material receiving.

[0075] At the same time, the setting of the visual detection unit 5 provides additional monitoring guarantee for the feeding process. Through photographing to detect the position and state of the materials, abnormal conditions of the materials on the separation seat 40 can be found in time, such as the materials not being taken away, the materials position deviating, etc., and timely measures can be taken for correction, which helps to avoid subsequent processing errors caused by material problems, and improves the product qualification rate and the stability of the production process.

[0076] In addition, the feeding device has simple mechanical structure, which can reduce the production manufacturing cost.

[0077] Further, the material receiving unit 4 comprises:

[0078] a material receiving frame 41;

[0079] a synchronous wheel set, which is installed on the material receiving frame 41 and comprises a driving wheel 42, a driven wheel 43 and a synchronous belt 44 installed on the driving wheel 42 and the driven wheel 43; in the embodiment, a sensor can also be arranged on the side of the driven wheel 43 away from the separation seat 40 to ensure the origin position and be used for servo motor zero return;

[0080] a motor 45, which is installed on the material receiving frame 41 and is in transmission connection with the driving wheel 42; in the embodiment, the motor 45 is a servo motor;

[0081] a rotating block 46, which is fixedly installed on the outside of the driven wheel 43 and rotates synchronously with the driven wheel 43; in the embodiment, the rotating block 46 is coaxially arranged with the driven wheel 43. The coaxial arrangement of the rotating block 46 and the driven wheel 43 makes the center of gravity of the rotating block 46 always located on the rotation axis during the rotation of the rotating block 46. The coaxial structure can effectively avoid the problem of unbalanced centrifugal force caused by the deviation of the center of gravity, so as to ensure that the separation seat 40 and the rotating block 46 can rotate in a stable state.

[0082] a separation seat 40, which is fixedly installed on the rotating block 46 and is provided with a material receiving position 401.

[0083] In operation, the motor 45 drives the driving wheel 42 to rotate, and the driven wheel 43 rotates synchronously, and then the rotating block 46 installed on the driven wheel 43 rotates synchronously, and finally the rotating adjustment of the separation seat 40 is realized, which is beneficial to realize the butt joint with the inclined straight vibration track 30 in the inclined straight vibration track unit 3, and realize the material transfer.

[0084] The whole structure of the receiving unit 4 is compact and reasonable, and each component is installed on the receiving rack 41 to form an organic whole. The connection between the synchronous wheel set, the motor 45, the rotating block 46 and the separation seat 40 is close and stable, which reduces the risk of failure caused by loose and displacement of components. This compact structure not only facilitates installation, debugging and maintenance, but also adapts to more complex production environment, occupies small space and improves the space utilization rate of production site.

[0085] Further, the receiving unit 4 also includes a flow meter, which is in communication with the internal vacuum system pipeline of the separation seat. At the same time, the pipeline of the internal vacuum system of the separation seat is in communication with the receiving position 401 of the separation seat 40. When the material is contained in the receiving position 401 of the separation seat 40, the material can block the airflow channel of the internal vacuum system of the separation seat. At this moment, the measured value of the flow meter in communication with the internal vacuum system pipeline of the separation seat changes dynamically, and it is judged that the material on the separation seat is in place based on this.

[0086] Further, the receiving unit 4 also includes a fixed base 47 installed at the bottom of the receiving rack 41 and a three-axis adjustment assembly 48 installed on the fixed base 47. The fixed base 47 is used as the basic supporting component of the whole receiving unit, which is stably placed on the corresponding installation plane to provide a stable installation foundation for other components. The adjustment end of the three-axis adjustment assembly 48 is connected with the receiving rack 41, and the three-axis adjustment assembly 48 can adjust the position of the receiving rack 41 installed on the fixed base 47 through the adjustment function in X, Y and Z three axes, and then adjust the butt joint position of the separation seat 40 and the inclined straight vibration track 30 to realize precise butt joint.

[0087] Further, the receiving unit 4 also includes a high-pressure pipeline, which is in communication with the receiving position 401 of the separation seat 40, and the residual material in the receiving position 401 can be completely blown clean by using the high-pressure airflow in the high-pressure pipeline.

[0088] Further, the camera detection unit 5 includes a light source 50 for illuminating the separation seat 40 of the receiving unit 4, a prism arranged at the position of the light source 50, and a lens 51 opposite to the prism. When the camera detection unit 5 takes a photo of the separation seat, the light reflected by the material is refracted by the prism at the position of the light source 50, and then propagates to the position of the lens 51 according to a specific optical path, so as to realize the optical imaging process of the material.
