Description

Technical Field

[0001] The invention belongs to the technical field of feeding mechanisms, and in particular relates to a feeding method and a feeding device with inclined feeding and orderly separation. Background Art

[0002] In the field of automated production, the feeding process plays a key role in the efficient and accurate assembly of products. Vibrating plate feeding, as a common auxiliary feeding method, is widely used in various production lines. It can arrange a variety of materials in a certain degree of order, provide a material basis for subsequent automatic assembly equipment, and help the various components of the product to be smoothly assembled into a complete finished product.

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

[0004] First, ultra-thin materials are light and flexible, and are prone to overlap during the traditional feeding process. This not only hinders the normal feeding process, but may also cause subsequent processing equipment to jam, seriously affecting production continuity.

[0005] Secondly, the detection of the presence of ultra-thin materials has become a thorny issue. On the one hand, conventional detection methods based on physical contact or simple sensing are difficult to accurately capture the subtle position changes of thin and light materials; on the other hand, due to the characteristics of the material, it is highly sensitive to the detection environment, and slight external interference may cause detection errors, making it impossible to accurately judge whether the material has been accurately delivered to the designated location, thereby affecting the accuracy of product assembly.

[0006] Third, the feeding efficiency needs to be improved. When processing ultra-thin materials, the existing feeding method has a significant reduction in overall feeding speed due to frequent blockages of materials and delays in the detection process, making it difficult to meet the needs of large-scale, continuous production operations for rapid material flow.

[0007] Based on this, the present invention provides a feeding method and a feeding device with inclined feeding and orderly separation to overcome the above-mentioned defects. Summary of the invention

[0008] The first object of the present invention is to provide a feeding method with inclined feeding and orderly separation. The feeding method makes the material transfer process from the inclined direct vibration track to the separation seat more efficient through the cooperation of the direct vibration vacuum system and the material receiving vacuum system. In addition, when the material is transferred, the material receiving vacuum system of the material receiving unit will suck the material at the critical point of the inclined direct vibration track into the separation seat. After the material is completely sucked in, the air flow channel is blocked, causing the connected flow meter reading to change dynamically. This change serves as the key to judging whether the material is in place, accurately controlling the material transfer and improving the processing accuracy.

[0009] The present invention adopts the following technical solution: a feeding method for inclined feeding and orderly separation, which comprises the following steps:

[0010] S01: The material in the accumulator is vibrated and fed to the bottom of the spiral feeding track in the circular vibration feeding unit by the circular vibration feeding unit, and the material climbs disorderly along the spiral feeding track and is gradually arranged in a regular manner, and enters the inclined straight vibration track set by the inclined straight vibration track unit;

[0011] S02: The inclined straight vibration track unit pushes the received materials along the predetermined direction of the inclined straight vibration track, driving the materials 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 direct vibration track, the direct vibration vacuum system of the inclined direct vibration track unit is turned on to absorb the material at the critical position of the inclined direct vibration track;

[0013] S04: Drive the separation seat in the material receiving unit to rotate until the separation seat is flush with the inclined surface of the material-carrying material on the inclined direct vibration track, and the direct vibration vacuum system is closed. At the same time, the material receiving vacuum system of the material receiving unit is opened, and the material at the critical position of the inclined direct vibration track is sucked into the separation seat; when the material is completely sucked into the separation seat, the material blocks the air flow channel of the vacuum system inside the separation seat. At this moment, the reading measured by the flow meter connected to the vacuum system pipeline inside the separation seat changes dynamically immediately, based on which it is judged that the material on the separation seat is in place, and then the direct vibration vacuum system is opened for the second time;

[0014] S05: The separation seat in the material receiving unit is driven to rotate to a horizontal position again, and the material receiving vacuum system is closed, waiting for the material to be taken away; if the vacuum reading monitored in real time by the flow meter is consistent with the characteristic value recorded when the material blocks the vacuum system inside the separation seat, it indicates that the material has not been sucked away; at this time, the separation seat in the material receiving unit is driven to rotate to a preset position, and the backflush program is started to completely blow away the residual material on the separation seat;

[0015] S06: After cleaning, continue to drive the separation seat to rotate until it is flush with the inclined surface of the material carrying material on the inclined straight vibration track, and repeat the above operation in a cycle.

[0016] Furthermore, in step S04, when the material is completely sucked into the separation seat, the camera detection unit takes a picture of the separation seat to determine again whether the material is in place on the separation seat; if the material is in place on the separation seat, the direct vibration vacuum system is turned on for the second time and the subsequent steps S05 and S06 are continued.

[0017] Furthermore, in step S06, after the separation seat is driven to rotate until it is flush with the inclined surface carrying the material on the inclined straight vibration track, the camera detection unit takes a photo of the separation seat again for re-inspection to determine whether the material on the separation seat has been taken away; if the material has not been taken away, the separation seat in the rotating material receiving unit is returned to the preset position, and the back-blowing program is started to thoroughly blow away the residual material on the separation seat, and then continue to execute step S06.

[0018] Furthermore, 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 invention has the following beneficial effects:

[0020] In the feeding method of the present invention, the material is fed in an inclined manner and separated in an orderly manner. 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 into a uniform direction. The orderly arrangement of the material is conducive to reducing the blockage and collision of the material during the transportation process, ensuring the stability and continuity of the feeding process and improving the overall production efficiency. Then, the inclined straight vibration track unit can push the material with a stable and orderly propulsion force, ensuring that the material can move forward at a predetermined speed and direction, and there will be no material accumulation or uneven transportation speed.

[0021] At the same time, the cooperation between the direct vibration vacuum system and the material receiving vacuum system makes the material transfer process from the inclined direct vibration track to the separation seat more efficient. The direct vibration vacuum system is turned on when the material reaches the critical position at the front end of the inclined direct vibration track to create a vacuum adsorption environment; when the material receiving vacuum system sucks the material into the separation seat and confirms that the material is in place through the flow meter, the direct vibration vacuum system is turned on again to further assist the stable placement of the material in the separation seat, and also prepare for the next material transfer. This close cooperation reduces the stagnation time during the material transfer process and improves the overall feeding efficiency, which is especially suitable for large-scale, continuous production operations.

[0022] In addition, during the material transfer process, the material receiving vacuum system of the 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 air flow channel of the vacuum system inside the separation seat. At this time, the reading measured by the flow meter connected to the vacuum system pipeline inside the separation seat changes dynamically. This change becomes a 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 vacuum system pipeline inside the separation seat. For some fragile and easily damaged materials (such as ultra-thin materials, precision film materials, etc.), the material scratches and collision damages that may be caused by traditional contact detection are avoided, ensuring the integrity of the material during the transfer process. And through this precise monitoring, it is ensured that the amount and position of each material transfer can be accurately controlled, avoiding the omission or excessive inhalation of materials, improving the accuracy and consistency of material processing, and effectively solving the problem of ultra-thin materials that are difficult to accurately detect the position by conventional means. At the same time, during the entire feeding process, the flow meter continuously detects the air pressure conditions, which is equivalent to real-time monitoring of the material transfer process. Once abnormal air pressure fluctuations are found, it may indicate problems with material transfer, such as material blockage, vacuum system leakage, etc. The system can quickly make adjustments based on the information feedback from the flow meter to avoid further deterioration of the problem and ensure the stability and continuity of the feeding process.

[0023] The second object of the present invention is to provide a feeding device using the above-mentioned feeding method of inclined feeding and orderly separation, which comprises:

[0024] A hopper for holding materials;

[0025] A circular vibration feeding unit, which is arranged on one side of the accumulator and has a spiral feeding track;

[0028] A visual inspection unit is arranged above the material receiving unit.

[0029] Further, the material receiving unit comprises:

[0030] Material receiving rack;

[0033] A rotating block, the rotating block is fixedly mounted on the outside of the driven wheel and rotates synchronously with the driven wheel;

[0034] The separation seat is fixedly mounted on the rotating block and is provided with a material receiving position.

[0035] Furthermore, the rotating block is coaxially arranged with the driven wheel.

[0036] Furthermore, the material receiving unit also includes a flow meter, the flow meter is connected to the pipeline of the vacuum system inside the separation seat, and the pipeline of the vacuum system inside the separation seat is connected to the material receiving position of the separation seat.

DETAILED DESCRIPTION

[0047] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0048] The following is combined with Figure 1 To Attachment Figure 5 And specific embodiments, the present invention is described in detail:

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

[0050] S01: In the initial stage, the material in the accumulator 1 is vibrated and fed to the bottom of the spiral feeding track 20 in the circular vibration feeding unit 2. Under continuous vibration, the material climbs disorderly along the spiral structure of the spiral feeding track 20. During the climbing process, it is restricted by the physical form of the spiral feeding track 20 and gradually arranged in a regular and unified direction, and then smoothly connects to the inclined straight vibration track 30 provided in the inclined straight vibration track unit 3 to achieve preliminary guidance and sorting.

[0051] S02: The inclined straight vibration track unit 3, relying on its own vibration system, pushes the connected materials along the predetermined direction of the inclined straight vibration track 30 with a stable and orderly propulsion force, driving the materials in a direction away from the circular vibration feeding unit 2;

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

[0053] S04: Drive the separation seat 40 in the material receiving unit 4 to rotate until the separation seat 40 is flush with the inclined surface of the inclined straight vibration track 30 carrying the material, and a docking state is achieved. At the same time, the direct vibration vacuum system is turned off. At the same time, the material receiving vacuum system of the material receiving unit 4 is instantly activated and turned on, and under the action of vacuum suction, 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 vacuum system inside the separation seat. At this moment, the reading measured by the flow meter connected to the vacuum system pipeline inside the separation seat changes dynamically immediately. Based on this, it is judged that the material on the separation seat is in place, and then the direct vibration vacuum system is opened for the second time to adsorb and fix the material at the critical position of the inclined direct vibration track 30 to prevent material stacking.

[0055] S05: Drive the separation seat 40 in the material receiving unit 4 to rotate to a horizontal position again, close the material receiving vacuum system, and let the material stand still in the separation seat 40, waiting for the material to be taken away; if the material is taken away, the internal vacuum system of the separation seat 40 is connected to the outside world; on the contrary, if the vacuum reading monitored by the flow meter in real time is consistent with the characteristic value recorded when the material blocks the internal vacuum system of the separation seat 40, it indicates that the material has not been sucked away. At this time, drive the separation seat 40 in the material receiving unit 4 to rotate to a preset position, start the back-blowing program, and thoroughly blow away the residual material on the separation seat 40. In this embodiment, a high-pressure airflow is used to thoroughly blow away the residual material on the separation seat 40. It should be noted that the present invention does not limit the way in which the material is taken away, and it can be designed and selected by those skilled in the art according to the actual situation. For example, 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 until it is flush with the inclined surface of the material carrying material on the inclined straight vibration track 30, and repeat the above series of operations in a cycle to achieve a continuous, efficient and accurate inclined feeding and orderly separation feeding process.

[0057] In the feeding method of the present invention, the material passes through the climbing process of the spiral feeding track 20, and the physical form of the track is used to arrange the disordered materials into a uniform direction. The orderly arrangement of materials is conducive to reducing the blockage and collision of materials during the transportation 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 push the material with a stable and orderly propulsion force, ensuring that the material can move forward at a predetermined speed and direction, and there will be no material accumulation or uneven transportation speed.

[0058] At the same time, the cooperation between the direct vibration vacuum system and the material receiving vacuum system makes the material transfer process from the inclined direct vibration track 30 to the separation seat 40 more efficient. The direct vibration vacuum system is turned on when the material reaches the front end critical position of the inclined direct vibration track 30 to create a vacuum adsorption environment; when the material receiving vacuum system sucks the material into the separation seat 40 and confirms that the material is in place through the flow meter, the direct vibration vacuum system is turned on again to further assist the stable placement of the material in the separation seat 40, and also prepare for the next material transfer. This close cooperation reduces the stagnation time during the material transfer process and improves the overall feeding efficiency, which is particularly suitable for large-scale, continuous production operations.

[0059] In addition, during the material transfer process, the material receiving vacuum system of the material 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 air flow channel of the vacuum system inside the separation seat. At this time, the reading measured by the flow meter connected to the vacuum system pipeline inside the separation seat changes dynamically, and this change becomes a 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 vacuum system pipeline inside the separation seat. For some fragile and easily damaged materials (such as ultra-thin materials, precision film materials, etc.), the material scratches and collision damages that may be caused by traditional contact detection are avoided, ensuring the integrity of the material during the transfer process. And through this precise monitoring, it is ensured that the amount and position of each material transfer can be accurately controlled, avoiding the omission or excessive inhalation of materials, improving the accuracy and consistency of material processing, and effectively solving the problem of ultra-thin materials that are difficult to accurately detect the position by conventional means. At the same time, during the entire feeding process, the flow meter continuously detects the air pressure conditions, which is equivalent to real-time monitoring of the material transfer process. Once abnormal air pressure fluctuations are found, it may indicate problems with material transfer, such as material blockage, vacuum system leakage, etc. The system can quickly make adjustments based on the information feedback from the flow meter to avoid further deterioration of the problem and ensure the stability and continuity of the feeding process.

[0060] In summary, the feeding method of the present invention solves the problems of easy stacking of ultra-thin materials, inaccurate detection of arrival, and low feeding efficiency.

[0061] Furthermore, in step S04, when the material is completely sucked into the separation seat 40, the camera detection unit 5 takes a picture of the separation seat 40 to determine again whether the material is in place on the separation seat 40. If the material is in place on the separation seat 40, the direct vibration vacuum system is turned on for the second time, and the subsequent steps S05 and S06 are continued.

[0062] In step S04, the flow meter is used to detect whether the material blocks the vacuum system inside the separation seat 40 to preliminarily determine whether the material is in place, and then the camera detection unit 5 is used to take a photo of the separation seat 40 for secondary judgment. This dual detection mechanism greatly improves the accuracy of determining whether the material is accurately in place. Among them, the flow meter detection is mainly based on the physical characteristics of the vacuum system, while the camera detection is directly confirmed from a visual perspective, which makes up for the shortcomings of a single detection method and enhances the detection ability of the entire 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 placement status. When quality problems occur in the product, these photos can be viewed to trace back to the initial state of the material in the separation seat 40 to analyze whether the quality problem is caused by inaccurate material placement.

[0064] More specifically, in step S06, after the separation seat 40 is driven to rotate to be flush with the inclined surface of the inclined straight vibration track 30 carrying the material, the camera detection unit 5 takes another photo of the separation seat 40 for re-inspection to determine whether the material on the separation seat 40 has been removed. If the material has not been removed, the separation seat 40 in the rotating material receiving unit 4 is rotated to a preset position, and 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] In step S06, the camera inspection unit is added to re-inspect the material on the separation seat in an intuitive visual way to confirm whether the material has been removed. Compared with the inspection method that relies solely on the vacuum system, the camera photo re-inspection provides more direct and accurate information on the material status, avoiding subsequent production errors caused by misjudgment, thereby reducing the number of production interruptions caused by material residues and improving the stability and continuity of the production process. This is particularly important for large-scale, automated production lines, which can significantly improve production efficiency and product quality stability.

[0066] Furthermore, 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 location of the light source, and then propagates to the location of the lens along 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 evenly, which helps to reduce the imaging shadows or bright spots caused by uneven light, thereby improving the clarity and contrast of the imaging.

[0067] Based on the above-mentioned feeding method with inclined feeding and orderly separation, the present invention also provides a feeding device, such as Figures 1 to 5 As shown, it includes:

[0068] A hopper 1, used for containing materials;

[0069] A circular vibration feeding unit 2, which is arranged on one side of the accumulator 1 and has a spiral feeding track 20;

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

[0071] A material receiving unit 4, which is arranged at the discharge end of the inclined straight vibration track unit 3 and has a material receiving vacuum system for transferring adsorbed materials; and the material transfer is achieved through the cooperation between the material receiving unit 4 and the inclined straight vibration track unit 3;

[0072] The visual inspection unit 5 is arranged above the material receiving unit 4 and is used to take pictures of the separation seat 40 in the material receiving unit 4 and detect whether there is material on the separation seat 40.

[0073] During operation, the material in the accumulator 1 is vibrated and fed to the bottom of the spiral feeding track 20 in the circular vibration feeding unit 2 by the circular vibration feeding unit 2. The circular vibration feeding unit 2 causes the material to climb up from the bottom along the spiral feeding track 20 in an irregular manner through vibration. During this process, the material is gradually arranged in a regular manner and in a unified direction due to the restriction of the spiral structure, and then the material smoothly enters the inclined straight vibration track 30 of the inclined straight vibration track unit 3. The inclined straight vibration track unit 3 uses its own vibration system to push the material away from the circular vibration feeding unit 2 with a stable propulsion force. As the material continues to advance on the inclined straight vibration track 30, when it reaches its frontmost critical position, the material is transferred through cooperation with the material receiving unit 4. At the same time, this process cooperates with the visual inspection unit 5 to achieve precise feeding.

[0074] The feeding device of the present invention realizes the orderly arrangement and stable transportation of materials by combining 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. The materials can maintain a stable speed and arrangement during the climbing and straight-line pushing process, which provides a reliable material flow for subsequent precise material connection and processing. The close cooperation between the various units of the entire feeding device forms a stable feeding system, reducing the risk of production interruption caused by problems such as poor material transportation and inaccurate material connection.

[0075] At the same time, the setting of the visual inspection unit 5 provides additional monitoring guarantee for the feeding process. By taking pictures to detect the position and state of the material, it is possible to promptly discover abnormal conditions of the material on the separation seat 40, such as the material not being taken away, the material position being offset, etc., and take timely measures to correct it, which helps to avoid subsequent processing errors caused by material problems and improve the product qualification rate and the stability of the production process.

[0076] In addition, the feeding device has a simple mechanical structure and can reduce production costs.

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

[0078] Material receiving frame 41;

[0079] A synchronous wheel set, the synchronous wheel set is installed on the receiving frame 41, and the synchronous wheel set includes 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 this embodiment, a sensor can also be set on the side of the driven wheel 43 away from the separation seat 40 to ensure the origin position for the servo motor to return to zero;

[0080] A motor 45, the motor 45 is mounted on the receiving frame 41 and is in driving connection with the driving wheel 42; in this embodiment, the motor 45 is a servo motor;

[0081] The rotating block 46 is fixedly mounted on the outside of the driven wheel 43 and rotates synchronously with the driven wheel 43; in this embodiment, the rotating block 46 is coaxially arranged with the driven wheel 43. The rotating block 46 is coaxially arranged with the driven wheel 43, so that the center of gravity of the rotating block 46 is always located on the rotation axis during the rotation process. The coaxial structure can effectively avoid the problem of unbalanced centrifugal force caused by the offset of the center of gravity, thereby ensuring that the rotating block 46 and the separation seat 40 mounted thereon can rotate in a stable state.

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

[0083] During operation, the motor 45 drives the driving wheel 42 to rotate, driving the driven wheel 43 to rotate synchronously, and then drives the rotating block 46 installed on the driven wheel 43 to rotate synchronously, and finally realizes the rotation adjustment of the separation seat 40, which is conducive to the docking with the inclined straight vibration track 30 in the inclined straight vibration track unit 3, and realizes material transfer.

[0084] The structural layout of the entire receiving unit 4 is compact and reasonable, and all components are installed on the receiving frame 41 to form an organic whole. The connection between the synchronous wheel group, the motor 45, the rotating block 46 and the separation seat 40 is tight and stable, reducing the risk of failure caused by loose components, displacement and other problems. This compact structure is not only easy to install, debug and maintain, but also can adapt to more complex production environments, occupy less space, and improve the space utilization rate of the production site.

[0085] Furthermore, the material receiving unit 4 also includes a flow meter, which is connected to the pipeline of the internal vacuum system of the separation seat. At the same time, the pipeline of the internal vacuum system of the separation seat is connected to the material receiving position 401 of the separation seat 40; when the material is contained in the material receiving position 401 of the separation seat 40, the material can block the air flow channel of the internal vacuum system of the separation seat. At this moment, the reading measured by the flow meter connected to the pipeline of the internal vacuum system of the separation seat immediately changes dynamically, based on which it is judged that the material on the separation seat is in place.

[0086] Furthermore, the material receiving unit 4 also includes a fixed base 47 installed at the bottom of the material receiving frame 41, and a three-axis adjustment component 48 installed on the fixed base 47. Among them, the fixed base 47 is the basic support component of the entire material 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 component 48 is connected to the material receiving frame 41. The three-axis adjustment component 48 can accurately adjust the position of the material receiving frame 41 installed on the fixed base 47 by virtue of its own adjustment function in the three axes of X, Y, and Z, and then adjust the docking position of the separation seat 40 and the inclined straight vibration track 30 to achieve precise docking.

[0087] Furthermore, the material receiving unit 4 also includes a high-pressure pipeline, which is connected to the material receiving position 401 of the separation seat 40. The high-pressure airflow in the high-pressure pipeline can be used to completely blow away the residual material on the material receiving position 401.

[0088] Furthermore, the camera detection unit 5 includes a light source 50 for illuminating the separation seat 40 on the material 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 picture 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 along a specific optical path, thereby realizing the optical imaging process of the material.

[0089] The present invention is further described above with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in the field after reading this specification are all within the scope of protection of the present invention.
