Description

Technical Field

[0001] The invention relates to the technical field of feeding devices, and in particular to a feeding device. Background Art

[0002] IC tubes are packaging tubes for IC, integrated circuits, integrated blocks, semiconductors, electronic components, transformers and precision electronic components. They are mainly used as packaging materials to prevent damage to parts during transportation and to prevent static electricity from causing static damage to components during transportation turnover. When in use, it is necessary to take the IC material out of the IC tube and place the IC material on the conveyor belt. After the IC material is transported to the designated location, it is grabbed by a robot and installed on the PCB board. The current method used on the market to take IC materials out of the IC tube is to set an air blowing nozzle at the rear end of the IC tube so that the air flow is blown into the IC tube through the air blowing nozzle, thereby pushing the IC material in the IC tube to slide out of the IC tube from the front end of the IC tube. The conveyor belt and the IC tube are set accordingly so that the IC material that slides out of the IC tube can fall exactly on the conveyor belt.

[0003] During this process, the airflow from the blowing nozzle will be blown onto the conveyor belt after being guided by the IC tube, and will have airflow interference on the IC material on the conveyor belt. Specifically, the airflow has a larger flow space after flowing out of the IC tube, and the downward diffusion of the airflow is blocked by the conveyor belt. Most of the airflow will diffuse and flow upward or to the left and right. Therefore, the thrust of the airflow on the rear end of the IC material will have upward, left and right components, and some of the airflow that cannot diffuse and flow downward will pass between the IC material and the conveyor belt. The generated gas pressure will produce an upward pressure on the IC material, which makes the IC material tend to be lifted and separated from the conveyor belt, and causes the IC material to roll on the conveyor belt due to uneven force, hit other IC materials on the conveyor belt, cause multiple IC materials to separate from the conveyor belt, or stack on the conveyor belt, affecting the conveyor belt's feeding of the robot.

[0004] On the other hand, since the air nozzle blows air to the rear end of the IC tube, and when the IC tube is full or has multiple IC materials, the airflow will lose a part of energy each time it passes through an IC material, and the IC material at the front end of the IC tube will be pushed out. The energy of the airflow flowing out of the front end of the IC tube is relatively low, and will not have much impact on the IC material on the conveyor belt; and as the IC material in the IC tube decreases, the energy lost by the airflow in the IC tube also decreases accordingly. The energy of the airflow flowing out of the front end of the IC tube is relatively high, which will interfere with the IC material on the conveyor belt and affect the conveyor belt's feeding of the robot.

[0072] The invention provides a feeding device.

[0073] See also Figures 1 to 5 In one embodiment of the present invention, the feeding device includes a mounting seat 100, a base 200, a rear support assembly 300, a front support assembly 400 and a vibration assembly 500. The base 200 is arranged at the front side of the mounting seat 100 and is located below the mounting seat 100. A conveying trough 21 is provided on the base 200. A feed port 213 and a discharge port 214 are respectively provided at opposite ends of the conveying trough 21. The rear support assembly 300 is arranged on the mounting seat 100 and includes a rear support block 31. The rear support block 31 is used to support the rear end of the material pipe. The front support assembly 400 is arranged on the mounting seat 100 and includes a front support block 41. The front support block 41 is used to support the front end of the material pipe. A accommodating space is formed above the front support block 41 and the rear support block 31. 13, the rear supporting block 31 supports the rear end of the material pipe and the front supporting block 41 supports the front end of the material pipe, so that the material pipe is in the accommodating space 13, the front supporting block 41 is lower than the rear supporting block 31, so that the front end of the material pipe in the accommodating space 13 is tilted downward, so that the material in the material pipe has a tendency to slide out of the material pipe along the tilted direction, the material pipe is in contact with the feed port 213 of the conveying trough 21, and the material in the material pipe can slide into the conveying trough 21, the vibration component 500 is arranged on the base 200, and the vibration component 500 includes a vibration driving member 51, and the vibration driving member 51 is arranged near the feed port 213, so as to vibrate the material pipe in the accommodating space 13, and the material in the material pipe slides out of the material pipe along the tilted direction by itself under the action of vibration. When the material tube is full or contains a large amount of material, the vibration component 500 provides kinetic energy for vibration to the material tube. After the material tube vibrates the material away from the material tube, the material tube loses a small amount of kinetic energy, and the vibration component 500 compensates for the kinetic energy on the material tube to maintain the kinetic energy on the material tube at a certain value, so that the material tube can vibrate the material away without vibrating too much in the accommodating space 13 and causing separation from the front support block 41 and the rear support block 31.

[0074] In the first real-time mode, the vibration assembly 500 further includes a vibration block 52, which is disposed on the base 200 and exposed on the end surface of the base 200, abutting against the front end of the material tube, and the vibration block 52 is drivingly connected to the vibration driving member 51. That is, when the vibration driving member 51 is working, only the vibration block 52 is vibrated by the vibration driving member 51, thereby driving the material tube to vibrate, thereby preventing the vibration driving member 51 from driving the base 200 to vibrate. In other embodiments, the vibration driving member 51 may also be exposed on the base 200 and abut against the front end of the material tube.

[0075] In the first real-time mode, the feeding device further includes at least three photoelectric sensors 700, at least one of which is disposed on the base 200 and is disposed near the feed port 213 to sense the material at the front end of the material tube, at least one of which is disposed near the front end of the first slot section 211 to sense the material entering the first slot section 211, and at least one of which is disposed near the rear end of the first slot section 211 to sense the material entering the second slot section 212. The photoelectric sensor 700 near the feed port 213 is used to detect whether there is material at the front end of the material tube. In this embodiment, the photoelectric sensor 700 is configured as a light sensor. In other embodiments, the photoelectric sensor 700 is configured as an infrared sensor or a Hall sensor.

[0076] In the first real-time mode, the feeding device further comprises a blowing assembly 600, which is arranged on the mounting seat 100, and comprises a blowing nozzle 61 and a solenoid valve connected to the blowing nozzle 61. The blowing nozzle 61 is arranged relative to the rear end of the material pipe, and is used to blow air from the rear end of the material pipe into the material pipe so that the material in the material pipe moves out of the material pipe. The solenoid valve is used to control the size of the airflow provided to the blowing nozzle 61. When the photoelectric sensor 700 near the feed port 213 does not detect the material, the vibration assembly 500 and the blowing assembly 600 will work simultaneously, and the blowing assembly 600 will blow air into the material pipe to blow out the stuck material, and the material stuck at the rear end or middle section of the material pipe can slide to the front end of the material pipe. The feeding device is calculated as one time interval. When the photoelectric sensor 700 near the feed port 213 does not detect the material for three consecutive times, the material pipe in the accommodating space 13 will be judged as an empty pipe, and the empty pipe will be withdrawn.

[0077] In the first real-time mode, the nozzle 61 is arranged on the upper side of the rear support block 31 and is arranged near the rear end of the rear support block 31. That is, when a material pipe is supported on the rear support block 31, the nozzle 61 can blow air to the material pipe supported on the rear support block 31. In particular, the rear support block 31 can move relative to the mounting seat 100 to achieve the replacement of the material pipe in the accommodating space 13. When the rear support block 31 moves, the nozzle 61 moves with the rear support block 31. It should be noted that the movement of the rear support block 31 refers to the position transformation between different spatial coordinate points, and the specific process includes but is not limited to translation along a straight line, movement along an arbitrary curve or rotation around an axis. In other embodiments, the nozzle 61 can also be arranged on the mounting seat 100 and located on the upper side of the rear support block, that is, when the rear support block 31 moves, the nozzle 61 does not move with the rear support block 31.

[0078] In the first real-time mode, the conveying trough 21 includes a first trough section 211 and a second trough section 212, the top end of the vibration block 52 is exposed on the base 200, the first trough section 211 is close to the feed port 213, and is formed on the vibration block 52, and the front end of the material pipe is in contact with the first trough section 211. The material in the material pipe will first fall into the first slot section 211, at which time the material is moved by vibration. When there is more material in the material pipe, the material that first falls into the first slot section 211 will move to the second slot section 212 under the push of the material behind and the vibration of the vibration block 52. When there is less material in the material pipe, it cannot effectively push the material in front, so that the material cannot enter the second slot section 212. The photoelectric sensor 700 near the front end of the first slot section 211 and the photoelectric sensor 700 near the feed port 213 both detect the material for a long time, while the photoelectric sensor 700 near the rear end of the first slot section 211 cannot detect the material. At this time, the blowing component 600 and the vibration component 500 work simultaneously to have a thrust on the material in the material pipe, so that the material in the material pipe can push the material falling into the first slot section 211. At the same time, part of the air flow will flow out from the front end of the material pipe to have a thrust on the material in the first slot section 211, and assist the material in the first slot section 211 to move toward the second slot section 212. The feeding device counts as one time at a certain time interval. When the material pipe is judged to be an empty pipe, and the photoelectric sensor 700 near the rear end of the first slot section 211 has not detected the material for three consecutive times, and the photoelectric sensor 700 near the front end of the first slot section 211 has not detected the material, it is judged that the material in the first slot section 211 has all entered the second slot section 212, and the empty pipe conveying airflow is no longer needed, and the empty pipe can be withdrawn. In particular, when the photoelectric sensor near the feed port 213 detects the material at the front end of the material pipe, it is judged that there is material in the material pipe, the blowing component 600 will stop working, and the vibration component 500 will continue to work. When the photoelectric sensor 700 near the rear end of the first slot section 211 has not detected the material for a long time, it is judged that the material in the material pipe is small, and the blowing component 600 will restart to assist the material conveying in the first slot section 211. In other embodiments, the exposed area of ​​the vibration block 52 on the base 200 may be smaller, and only exposed at the feed port 213 , that is, the conveying trough 21 does not have the first trough section 211 and the second trough section 212 .

[0079] In the first real-time mode, the feeding device further includes a conveyor belt 22, which is arranged in the second slot section 212 to convey materials. The materials are conveyed to the discharge port 214, and the materials on the discharge port 214 can be grabbed by the manipulator. The vibration of the first slot section 211 does not affect the conveying of the materials on the second slot section 212. And the airflow blown out from the front end of the material pipe consumes the materials on the first slot section 211 and diffuses the airflow, and the airflow intensity flowing through the second slot section 212 is relatively weak, which will not affect the materials on the conveyor belt 22. That is, the operation of the blowing component 600 will not affect the materials in the second slot section 212.

[0080] In the first real-time mode, the front support assembly 400 further includes a front support driving member 42. The front support block 41 performs lifting motion under the drive of the front support driving member 42 and has a first position and a second position in the up-down direction. In the first position, the material tube in the receiving space 13 can be replaced; in the second position, the front support block 41 is lower than the rear support block 31, and the front end of the material tube is tilted downward. It can be understood that when replacing an empty tube placed at an angle, the new material tube needs to be tilted until it can be supported by the front support block 41 and the rear support block 31, but in this process, there is a risk of spilling the material in the new material tube out of the mounting seat 100 and the base 200. Therefore, the front support block 41 is enabled to move up and down. When the front support block 41 moves to the point where the material tube can be placed flat in the receiving space 13, the material tube in the receiving space 13 is replaced, which helps to improve the convenience of replacing the material tube and can prevent the material in the material tube from spilling out. In other embodiments, a damping groove may be provided on the front supporting block 41, and the bottom wall of the damping groove is lower than the end face of the rear supporting block 31. After the material tube falls into the damping groove, the side wall of the material tube rubs against the side wall of the damping groove, and the front end of the material tube can slide in the damping groove at a slower speed until the material tube abuts against the bottom wall of the damping groove.

[0081] It is understandable that most feeding devices on the market use the blowing assembly 600 to blow out the material in the material pipe. In this embodiment, the front support block 41 is arranged to be liftable, so that the front end of the first material pipe can be tilted downward, and the material in the first material pipe has a tendency to slide out from the front end of the first material pipe, which is more conducive to the material sliding out of the first material pipe, helping to improve the feeding efficiency of the feeding device. In other embodiments, the front support assembly 400 may not have the front support driving member 42, that is, the front support block 41 cannot be lifted, the first material pipe in the accommodating space 13 is placed straight, and the feeding operation starts straight.

[0082] Since most of the feeding devices on the market that can take out the materials in the material pipe adopt the method of vibrating the material pipe to vibrate the materials out of the material pipe, the material pipe will vibrate away from the preset feeding position during the vibration process, so as to cause the materials to spill out. In the first real-time mode, the feeding device also includes a clamping assembly 800, which is arranged on the mounting seat 100 and has a third state and a fourth state. In the third state, the clamping assembly 800 abuts against the first material pipe located in the accommodating space 13 to limit the movement of the first material pipe in the accommodating space 13, and in the fourth state, the clamping assembly 800 releases the restriction on the first material pipe. The clamping assembly 800 in the third state can limit the movement of the first material pipe during the vibration process to prevent the first material pipe from deviating from the preset feeding position on the feeding device, and the clamping assembly 800 in the fourth state will not interfere with the process of the first material pipe falling into the drop pipe channel 15 and the second material pipe entering the accommodating space 13. In other embodiments, the clamping assembly 800 may also be not provided.

[0083] In the first real-time mode, the clamping assembly 800 includes a clamping member 81 and a clamping driving member 82. The clamping member 81 moves along the first direction driven by the clamping driving member 82, and has a fifth position and a sixth position in the first direction. The first direction is the extension direction of the accommodating space. In the fifth position, the clamping member 81 is away from the material pipe. At this time, the front support block 41 is in the first position, or in the process of changing from the first position to the second position, so that the material pipe in the accommodating space 13 can be replaced, and the clamping member 81 avoids the moving track of the front end of the material pipe so as not to interfere with the first material pipe falling into the drop pipe channel. 15, and the process of the second material pipe entering the accommodating space 13, that is, the process of not interfering with the material return and material change of the feeding device, at this time, the front support block 41 is located in the first position, and corresponds to the fourth state of the clamping assembly 800, and the first direction is the extension direction of the accommodating space; in the sixth position, the clamping member 81 is in contact with the material pipe, and the clamping member 81 and the front support block 41 in the second position jointly clamp the front end of the material pipe to prevent the first material pipe from detaching from the front support block 41 during the vibration material taking process, and prevent the material pipe from tilting and sliding downward, so that the rear end of the material pipe slides off the rear support block 31, and at the same time, the front end of the material pipe corresponds to the feed port 213. In other embodiments, the clamping assembly 800 can also include two clamping members 81 respectively arranged on the upper and lower sides of the first material pipe, and the two clamping members 81 are respectively connected to the clamping drive member 82 and the fifth drive member. In another embodiment, the clamping assembly 800 may be omitted, and the top side surface of the front supporting block 41 may be roughened, or the material of the front supporting block 41 may be configured to have a larger friction coefficient, thereby increasing the friction between the front supporting block 41 and the material tube to prevent the material tube from sliding downward.

[0084] In the first real-time mode, the mounting seat 100 is provided with a first moving block 11 and a second moving block 12, and the first moving block 11 and the second moving block 12 can approach and move away from each other on the mounting seat 100, and the front support assembly 400 is provided on the first moving block 11, and the rear support assembly 300 is provided on the second moving block 12. Through the movement between the first moving module and the second moving module, the front support assembly 400 and the rear support assembly 300 can be adapted to material pipes of different lengths. Specifically, the first moving block 11 and the second moving block 12 are both provided with a long strip hole extending along the first direction, and the mounting seat 100 is provided with a plurality of mounting holes spaced along the first direction, and the screws can pass through the long strip holes and the mounting holes in sequence to install the first moving module and the second moving module. Further, the blowing assembly 600 is provided on the second moving block 12, and the clamping assembly 800 is provided on the first moving block 11. In other embodiments, the mounting seat 100 may not be provided with the first moving block 11 and the second moving block 12.

[0085] In the first real-time mode, the rear support assembly 300 is arranged on the mounting seat 100, and includes a rear support block 31, a rear support driving member 32 drivingly connected to the rear support block 31, and the front support block 41 and the rear support block 31 are spaced apart to form a drop tube gap 14 in the front-to-back direction of the mounting seat 100. The front support block 41 and the rear support block 31 are provided with a receiving space 13 above and a drop tube channel 15 below, and the receiving space 13, the drop tube gap 14 and the drop tube channel 15 are connected in sequence; the rear support block 31 can move under the drive of the rear support driving member 32 and has a third position and a fourth position. In the third position, the rear support block 31 supports the rear end of the material tube and the front support block 41 supports the front end of the material tube, so that the material tube is in the receiving space 13; in the fourth position, the rear support block 31 is separated from the rear end of the material tube, and the material tube can fall from the receiving space 13 into the drop tube gap 14 and the drop tube channel 15 under the action of gravity. By moving the rear support block 31 to a position away from the rear end of the material pipe, the drop tube interval 14 is increased, so that the rear end of the material pipe is suspended in the air and enters the drop tube interval 14, and then falls into the drop tube channel 15. When most of the structure of the material pipe is suspended in the air and only the front end of the material pipe is supported, the center of gravity of the material pipe is unstable, and the front end of the material pipe will tilt up and leave the front support block 41. At this time, the material pipe as a whole enters the drop tube channel 15, and then falls out of the feeding device, completing the withdrawal of the pipe. During the feeding process, the front and rear ends of the material pipe are supported by the front support block 41 and the rear support block 31 respectively, so that the material pipe can be stably placed on the feeding device. When withdrawing the pipe, the rear support block 31 is set away from the material pipe, so that the rear end and front end of the material pipe are separated from the rear support block 31 and the front support block 41 in turn, and the material pipe is in a suspended state, so that the entire material pipe can successfully detach from the feeding device. In this process, since most of the bottom surface of the material tube is in a suspended state, the bottom surface of the material tube will not be worn after long-term use, and the bottom surface at the front end of the material tube will remain in a smooth state, so that the front end of the material tube can be placed stably on the front supporting block 41, and will not affect the accurate feeding of the feeding device. After completing a tube withdrawal operation, the rear supporting block 31 moves from the fourth position back to the third position, so that a new material tube can be supported by the rear supporting block 31.

[0086] It should be noted that the movement of the rear support block 31 refers to the position transformation between different spatial coordinate points, and the specific process includes but is not limited to translation along a straight line, movement along an arbitrary curve, or rotation around an axis.

[0087] In the first real-time mode, the feeding device further includes a limiting component 900, which is arranged on the mounting seat 100 and has a first state and a second state. In the first state, the limiting component 900 limits the second material pipe from entering the receiving space 13; in the second state, the limiting component 900 releases the restriction on the second material pipe. Multiple material pipes can be stacked in the receiving space 13 and the material preparation space 16 from bottom to top. When the rear support block 31 moves back to the third position, the limiting component 900 can enter the second state, so that the second material pipe falls from the material preparation space 16 to the receiving space 13 from top to bottom, that is, the second material pipe replaces the original first material pipe without material and becomes the new first material pipe, and at this time, the new first material pipe has material. It can be understood that the third material pipe located on the upper side of the original second material pipe enters the lowest end position of the material preparation space 16 and becomes the new second material pipe. Then the limiting component 900 re-enters the first state to limit the new second material pipe and prevent it from entering the receiving space 13. In other embodiments, the material preparation space 16 may be arranged on one side of the accommodating space 13 in the left-right direction. In the first state, the limiting component 900 limits the second material pipe from entering the accommodating space 13. In the second state, the limiting component 900 releases the restriction on the second material pipe and pushes the second material pipe to move along the left-right direction to the accommodating space 13.

[0088] In the first real-time mode, the limiting assembly 900 includes a limiting member 91 and a limiting driving member 92 driving the limiting member 91. The limiting member 91 can move under the driving of the limiting driving member 92 and has a limiting position and a releasing position. In the limiting position, the limiting member 91 supports the bottom end of the second material tube. In the releasing position, the limiting member 91 is separated from the second material tube and corresponds to the second state of the limiting assembly 900. The limiting driving member 92 helps to realize automatic material replacement, eliminates the time of manually placing the material tube in the accommodating space 13, and improves the feeding efficiency of the feeding device. In another embodiment, the limiting driving member 92 may not be provided, and the limiting position and the releasing position are changed by manually controlling the movement of the limiting member 91. In other embodiments, in the limiting position, the limiting member 91 clamps the opposite sides of the second material tube and corresponds to the first state of the limiting assembly 900; in the releasing position, the limiting member 91 is separated from the second material tube and corresponds to the second state of the limiting assembly 900.

[0089] In the first real-time mode, specifically, when the first material pipe is feeding, the clamping member 81 is located at the sixth position, and the front supporting block 41 is located at the second position to lift the material pipe, and the clamping member 81 and the front supporting block 41 are able to fix the position of the first material pipe in the accommodating space 13. When the material in the first material pipe is fed, the rear supporting block 31 moves from the third position to the fourth position, so that the first material pipe enters the drop tube gap from the accommodating space 13, and then the clamping member 81 moves from the sixth position to the fifth position, so that the first material pipe falls into the drop tube channel 15. At this time, the limiting assembly 900 is in the first state to limit the second material pipe to prevent the second material pipe from leaving the material preparation space 16. Subsequently, the front supporting block 41 moves from the second position to the first position, the rear supporting block 31 moves from the fourth position to the third position, and then the limiting driving member 92 drives the limiting member 91 to move from the limiting position to the releasing position, so that the second material pipe falls from top to bottom into the accommodating space 13 to become a new first material pipe, and is supported by the front supporting block 41 and the rear supporting block 31. At this time, the new first material pipe is placed flat in the accommodating space 13, and the limiting driving member 92 drives the limiting member 91 to move from the releasing position to the limiting position to clamp the new second material pipe, thereby completing a material withdrawal operation and a material replacement operation; after the material replacement operation is completed, the front supporting block 41 moves from the first position to the second position, so that the front end of the new first material pipe can be tilted downward, and the clamping member 81 moves back from the fifth position to the sixth position, and clamps the new first material pipe together with the front supporting block 41 to start the feeding operation.

[0090] Furthermore, the feeding device also includes a base 200 and a conveyor belt 22. The base 200 is arranged on the front side of the mounting base 100 and is located below the mounting base 100. A conveyor trough 21 is formed on the upper side of the base 200. The conveyor trough 21 is used for the conveyed material to pass through. The conveyor belt 22 is arranged in the conveyor trough 21 to convey the material. A feed port 213 and a discharge port 214 are respectively provided at the opposite ends of the conveyor trough 21. The material on the discharge port 214 can be grabbed by a robot. When the front support block 41 is located in the second position, the front end of the first material pipe is arranged corresponding to the feed port 213, so that the material sliding out of the first material pipe can fall into the feed port 213.

[0091] In the first real-time mode, the mounting base 100 includes a substrate 18 extending in the up-down direction, the substrate 18 having a first side 182 and a second side 183 opposite to each other in the thickness direction, the material preparation space 16 is arranged on the first side 182, the clamping drive member 82 is arranged on the second side 183, and the extension direction of the clamping drive member 82 is the first direction, and is arranged close to the sixth position, and an avoidance opening 181 is provided at the front end of the substrate 18, and the clamping member 81 extends from the second side 183 through the avoidance opening 181 to the first side 182. When the clamping drive member 82 can drive the clamping member 81 to move along the first direction, it can be understood that the driving rod of the clamping drive member 82 can be telescopically moved in the first manner. Therefore, the clamping drive member 82 has a larger volume in the first direction. Therefore, in order to avoid increasing the volume of the feeding device in length (that is, the clamping drive member 82 and the clamping member 81 are arranged on the same side, and the clamping drive member 82 is arranged at the front end of the substrate 18, the driving rod of the clamping drive member 82 can extend along the first direction and telescopically toward the basic rear end, and when the clamping member 81 can be moved along the first direction, the moving path of the first material tube is avoided), the clamping member 81 and the clamping drive member 82 are respectively arranged on the first side 182 and the second side 183. At this time, the clamping drive member 82 does not need to avoid the moving path of the first material tube, and the driving rod of the clamping drive member 82 can telescopically move toward the front end of the substrate 18, which helps to reduce the length of the substrate 18 and reduce the volume of the feeding device in the length direction. In other embodiments, the clamping driving member 82 may extend in the up-down direction to move the clamping member 81 in the up-down direction.

[0092] In the first real-time mode, the rear support driving member 32 is arranged on the first side 182 and connected to the rear end face of the rear support block 31, which is located at the rear end face of the base plate 18, and the front support driving member 42 is arranged on the first side 182 and connected to the bottom side of the front support block 41, which is located at the front end face of the base plate 18. Since the material preparation space 16, the accommodating space 13, the tube drop interval 14 and the tube drop channel 15 are all arranged in the up-down direction and are sequentially connected, that is, the movement path of the material tube on the feeding device is arranged from top to bottom, in order to facilitate the installation of the front support assembly 400 and the rear support assembly 300 and to better match the path layout of the material tube, the rear support driving member 32 and the front support driving member 42 are both installed on the base plate 18 extending in the up-down direction, the front support block 41 is located at the front end face of the base plate 18, and the rear support block 31 is located at the rear end face of the base plate 18, which is conducive to reducing the lateral space volume of the feeding device. In other embodiments, the rear supporting driving component 32 and the front supporting driving component 42 may be respectively disposed at the front and rear ends of the base plate 18 .

[0093] In the first real-time mode, the front and rear surfaces of the substrate 18 are provided with material storage grooves 17 arranged opposite to each other, and the groove bottom walls of the two material storage grooves 17 extend in the up-down direction, and the two material storage grooves 17 enclose a material preparation space 16, the front end of the material pipe in the material preparation space 16 points to the groove bottom wall of the material storage groove 17 located at the front end surface of the substrate 18, and the rear end of the material pipe in the material preparation space 16 points to the groove bottom wall of the material storage groove 17 located at the rear end surface of the substrate 18, and at least two limiting components 900 are provided, and are respectively arranged on the rear end surfaces of the groove bottom walls of the two material storage grooves 17. The groove side walls of the material storage groove 17 can limit the material pipe in the material preparation space 16 from shaking in the left-right direction, and the interval between the two material storage grooves 17 facilitates the worker to observe the number of material pipes in the material preparation space 16 and replenish the material pipes in time. In other embodiments, the material preparation space 16 can also be composed of a box body with a hollow bottom.

[0094] In the first real-time mode, the front support assembly 400 further includes a stopper 43 disposed on the front support block 41, and the stopper 43 can clamp the front end of the first material tube. In the process of the front support block 41 moving from the first position to the second position, in order to prevent the first material tube from sliding off the front support block 41, so that the first material tube falls into the material drop channel before feeding, in other embodiments, the stopper 43 may not be provided, the top side surface of the front support block 41 is made rough, or the material of the front support block 41 is configured to be a material with a large friction coefficient, so as to prevent the first material tube from sliding downward by increasing the friction between the front support block 41 and the first material tube.

[0095] In the first real-time mode, it is arranged on the base 200 and includes a driving member 26 and a conveying belt 22. The conveying belt 22 is driven by the driving member 26 to move at least partially in the conveying trough 21 along the first direction, and conveys the material from the feed port 213 to the discharge port 214; the limiting mechanism 28 includes a positioning piece 281 and a mounting plate 285. The positioning piece 281 is arranged downstream of the discharge port 214, and the mounting plate 285 is used to enable the positioning piece 281 to move relative to the base 200 to adjust the position of the positioning piece 281 in the first direction; the positioning piece 281 and the discharge port 214 are spaced apart in the first direction, and an avoidance gap 282 is formed between them; the photoelectric sensor 700 is arranged on the base 200 and is used to detect the material located in the avoidance gap 282. By setting a locking key, the positioning piece 281 can be adjusted along the first direction, so that the center points of materials of different sizes conveyed to the discharge port 214 can be maintained at the same position coordinate point, so that it is suitable for materials of various sizes and specifications, and is convenient for the material taking device to take materials. There is no need to stock positioning pieces 281 of different specifications, nor is there any need to replace positioning pieces 281 of different specifications when conveying materials of different sizes. Only the moving distance of the positioning piece 281 needs to be adjusted to keep the center points of materials of different sizes at the same position coordinate point. The operation is simpler and the time for finding a suitable positioning piece 281 and replacing it is saved, thereby improving the production efficiency of the feeding device.

[0096] On the other hand, the discharge port 214 of the conveying trough 21 is defined to be located in front of the feed port 213 thereof. The material located at the frontmost side is the material at the frontmost side of the conveying trough 21, and the material located at the next frontmost side is the material at the second frontmost side. The gap between the discharge port 214 and the positioning piece 281 forms an avoidance gap 282. When one end of the material at the frontmost side extends into the avoidance gap 282, it is detected by the photoelectric sensor 700, and the conveying belt 22 stops conveying. The material at the frontmost side slides a certain distance in the avoidance gap 282 under the action of inertia. The material on the second front side behind the discharge port 214 abuts against the positioning piece 281, and continues to slide under the action of inertia. When other materials approach the material on the front side, the speed of the material on the second front side is reduced in the long-distance friction with the conveyor belt 22, so that the collision force between the material on the second front side and the material on the front side is small and material stacking will not occur. Or when the material on the second front side approaches the material on the front side, the speed of the material on the second front side has stopped sliding in the long-distance friction with the conveyor belt 22, and material stacking will not occur. At the same time, for materials of different sizes and weights, by adjusting the position of the positioning piece 281 in the first direction, the width of the avoidance gap 282 can be adjusted, so that the avoidance gap 282 is greater than or equal to the distance required for material braking, so that other materials can reduce the sliding speed in the long-time friction with the conveyor belt 22, preventing other materials from stacking with the material on the front side, thereby affecting material collection.

[0097] The first direction is the front-to-back direction indicated in the figure. For the convenience of writing, the following text will be expressed as the first direction.

[0098] In the first real-time mode, the limiting mechanism 28 also includes a pad 287 disposed on the base 200, the mounting plate 285 is disposed on the upper side of the pad 287, the pad 287 is provided with a first mounting hole 288 for detachably connecting the mounting plate 285, and the positioning piece 281 is disposed on a side of the pad 287 close to the discharge port 214. When the mounting plate 285 is mounted on the first mounting hole 288, the mounting plate 285 is also limitedly connected to the positioning piece 281. When the position of the positioning block needs to be moved, the mounting plate 285 is removed from the pad 287, the positioning piece 281 is moved to a preset position along the first direction, and then the mounting plate 285 is connected to the pad 287. Further, the mounting plate 285 includes a second mounting hole 286 detachably connected to the backing plate 287, one of the first mounting hole 288 and the second mounting hole 286 includes an elongated hole extending along the first direction, and the mounting plate 285 and the backing plate 287 are fixed to each other by screws passing through the first mounting hole 288 and the second mounting hole 286, and the length of the elongated hole is the distance that the positioning block can move. Further, the second mounting hole 286 is configured as an elongated hole. The thickness of the mounting plate 285 is less than the thickness of the backing plate 287, and the mounting plate 285 is arranged on the upper side of the backing plate 287, so when the second mounting hole 286 is an elongated hole with an adjustable distance, the nut of the screw can easily press and fix the mounting plate 285. Furthermore, the positioning piece 281 and the mounting plate 285 are integrally formed, that is, the positioning piece 281 and the mounting plate 285 are bent and formed on the same plate, so that the positioning piece 281 can move with the mounting plate 285, and the production process of the positioning piece 281 and the mounting plate 285 is simplified. In other embodiments, two first mounting holes 288 can be provided, and they are arranged on opposite sides of the mounting plate 285. The screws are screwed into the first mounting holes 288 so that the nuts of the screws press the mounting plate 285, and then the mounting plate 285 is fixed on the pad 287. When it is necessary to move the positioning block, the nuts are moved away from the mounting plate 285, and the mounting plate 285 moves along the first direction between the two first positioning holes to adjust the position of the positioning block. After the positioning block moves to the preset position, the screws are screwed again so that the nuts of the screws press the mounting plate 285 and the pad 287. In another embodiment, the positioning piece 281 and the mounting plate 285 can be separately formed.

[0099] In the first real-time mode, the backing plate 287 is provided with a third notch 289 on one side close to the discharge port 214, the positioning piece 281 has a first end wall 283 and a second end wall arranged opposite to each other in the first direction, and two limiting side walls 284 connecting the first end wall 283 and the second end wall, the first end wall 283 extends out of the opening of the first notch, and the two limiting side walls 284 are embedded in the third notch 289, limiting the positioning piece 281 to be able to adjust and move only in the first direction, and it can be understood that the length of the third notch 289 in the first direction is the length of the first end wall 283 on the positioning block moving on the base 200, so as to prevent the first end wall 283 from extending into the discharge port 214 and hindering the material removal. In other embodiments, the limiting plate may not be provided with the third notch 289.

[0100] In the first real-time mode, the base 200 includes a table 23, the conveying trough 21 is formed on the upper side of the table 23, the table 23 is provided with a fifth mounting hole 231, the conveying belt transmission mechanism also includes a first pulley 27 corresponding to the discharge port 214, the first pulley 27 is rotatably arranged in the fifth mounting hole 231, and the limiting mechanism 28 also includes a cover plate 290 arranged between the table 23 and the pad 287, the cover plate 290 is covered in the fifth mounting hole 231, and is provided with a first notch to avoid the conveying belt 22. It should be noted that the upper side of the cover plate 290 is higher than the upper side of the conveying belt 22, which means that the height difference between the upper side of the cover plate 290 and the plate surface of the table 23 is greater than the height difference between the upper side of the conveying belt 22 and the plate surface of the table 23, based on the plate surface of the table 23. That is, the cover plate 290 can lift the pad 287 to prevent friction between the pad 287 and the conveying belt 22, resulting in surface wear of the conveying belt 22. At the same time, the cover plate 290 can prevent dust or moisture from falling into the first pulley 27 through the fifth mounting hole 231, so that the first pulley 27 does not rotate smoothly. In other embodiments, two cover plates 290 can be provided, and the two cover plates 290 are respectively arranged on both sides of the conveyor belt 22.

[0101] In the first real-time mode, the base 200 further includes at least two guide plates disposed on the upper side of the table 23, the at least two guide plates are spaced apart in a direction perpendicular to the first direction, and the conveying trough 21 is formed at intervals, and the guide plates are movably disposed on the base 200 to movably adjust the width of the conveying trough 21. The guide plates on both sides and the base 200 form a trough shape. In other embodiments, the base 200 may be concave to form a trough shape, and in this case, the width of the conveying trough 21 cannot be adjusted.

[0102] Further in the first real-time mode, a plurality of long strip holes extending in a direction perpendicular to the first direction are provided on the guide plate, and the long strip holes are fixed by screws, so as to realize the adjustable width of the conveying trough 21. The width of the conveying trough 21 is adjusted to be slightly larger than the width of the material, so that the material can pass through the conveying trough 21, and the placement position of the material on the conveying belt 22 can be adjusted during the material conveying process. In other embodiments, a plurality of long strip holes can also be provided on the guide plate, and then fixed by pins.

[0103] In the first real-time mode, the guide plate includes a first guide plate and a second guide plate. The second guide plate is arranged above the first guide plate, and the side edge of the second guide plate near the conveying groove 21 protrudes from the side of the first guide plate. The part of the second guide plate protruding from the first guide plate is used to limit the pins of the material. When the material includes pins and the material body, the pins are limited and guided by setting the second guide plate. When the material is normally transmitted on the conveying belt 22, the active gap is maintained to reduce friction. When the conveying state of the material on the conveying belt 22 is abnormal, for example, the material is tilted upward, the second guide plate can limit the pins of the material to prevent the material from overlapping and turning over during rapid transportation. By moving the first guide plate and the second guide plate separately, materials of different sizes can be flexibly adapted. In other embodiments, the second guide plate may not be provided. In another embodiment, the guide plate may not include the first guide plate and the second guide plate that are separately arranged.

[0104] In the first real-time mode, the base 200 further includes a material blocking plate 24 disposed on the upper side of the table 23, and a limiting groove 241 is formed on the lower side of the material blocking plate 24 corresponding to the conveying groove 21. The conveying groove 21 and the limiting groove 241 enclose a conveying channel 242, and the material is transported by the conveying belt 22 in the conveying channel 242. When the material is normally transmitted on the conveying belt 22, there is a gap between the bottom wall of the limiting groove 241 and the upper side of the material so as not to hinder the conveying of the material. When the conveying state of the material on the conveying belt 22 is abnormal, for example, when the material tilts upward, the bottom wall of the limiting groove 241 abuts against the raised part of the material to prevent the material from being further lifted. Further, the base 200 further includes a baffle 25 arranged near the discharge port 214, and a second notch 243 is arranged at one end of the baffle plate 24 near the discharge port, the second notch 243 is connected to the conveying channel 242, and the baffle 25 includes a connecting section 251 and an abutting section 252, the connecting section 251 is arranged on the upper side of the baffle plate 24, and the position of the abutting section 252 in the first direction can be adjusted, and the abutting section 252 extends along the first direction and extends into the second notch 243, and elastically abuts against the upper side of the material in the conveying trough 21. When the lifted material is transported to the second notch 243, the abutting section 252 of the baffle 25 elastically presses on the upper end of the material, and the material at the discharge port 214 is continuously taken away, and when the material at the second notch 243 is transported to the discharge port 214, the materials that are pushed against each other and lifted up are returned to a normal state, so that the state of the material at the discharge port 214 is normal, which is convenient for the material to be taken out from the discharge port 214. The installation position of the connecting section 251 on the material baffle plate 24 can be adjusted along the first direction, so that the position of the abutting section 252 in the second notch 243 can be adjusted according to the actual size of the material. Further, the connecting section 251 includes a sixth installation hole 254 extending along the first direction. That is, the sixth installation hole 254 is configured as an elongated hole extending along the first direction, so that the installation position of the connecting section 251 can be adjusted in the first direction. In other embodiments, the base 200 may not be provided with a material baffle plate 24. In another embodiment, the baffle plate 24 may not be provided with a second notch 243, or the connecting section 251 of the baffle plate 25 is fixedly connected to the material baffle plate 24.

[0105] In the first real-time mode, the baffle plate further includes an inclined surface section 253 connecting the connecting section 251 and the abutting section 252, and the inclined surface section 253 extends downwardly in a first direction to extend the abutting section 252 from the upper side of the baffle plate 24 into the conveying channel 242. It can be understood that the connecting section 251, the inclined surface section 253 and the abutting section 252 are bent and formed on the same plate, and when the abutting section 252 abuts against the upper end of the material, the connecting section 251 has elastic potential energy, so that the abutting section 252 exerts pressure on the material. In other embodiments, a spring can also be sandwiched between the connecting section 251 and the abutting section 252.

[0106] In the first real-time mode, the photoelectric sensor 700 includes a photoelectric sensor 700 disposed on the side of the conveying trough 21, and the light of the photoelectric sensor 700 is disposed in the avoidance gap 282. When the material blocks the light, the photoelectric sensor 700 transmits an electrical signal to the conveying belt transmission mechanism to stop the conveying belt 22 from transmitting. In other embodiments, the photoelectric sensor 700 may be disposed above the conveying trough 21. In another embodiment, the photoelectric sensor 700 may also be an ultrasonic sensor or a Hall sensor. Further, the photoelectric sensor 700 is configured as an infrared sensor. Further, the light of the photoelectric sensor 700 is disposed adjacent to the discharge port 214 to facilitate sensing whether the material enters the avoidance gap 282. In other embodiments, the light of the photoelectric sensor 700 may also be disposed in the middle of the avoidance gap 282. In another embodiment, it may also be a laser sensor.

[0107] In the second embodiment, the feeding device includes at least two feeding modules, and the plurality of feeding modules are arranged in the left-right direction. The feeding module includes a mounting seat 100, and the mounting seat 100 includes a feeding shell 19 and a base 200. The substrate 18 is arranged in the feeding shell 19, and the front end of the feeding shell 19 is connected to the rear end of the base 200. A accommodating space 13 is formed in the feeding shell 19, and the material pipe is placed in the accommodating space 13 along the front-back direction of the feeding shell 19. A conveying groove 21 is formed on the upper side of the base 200, and the conveying groove 21 is connected to the accommodating space 13. The accommodating space The material pipe in 13 can feed material to the conveying trough 21, and the conveying trough 21 is used for the conveyed material to pass through, and the conveying trough 21 extends along the front and rear direction of the base 200; the blowing assembly 600 is arranged in the feeding shell 19, including a blowing nozzle 61 and a first solenoid valve connected to the blowing nozzle 61, the blowing nozzle 61 is arranged relative to the rear end of the material pipe in the accommodating space 13, and is used to blow air into the material pipe from the rear end of the material pipe to move the material in the material pipe out of the material pipe, and the first solenoid valve is used to control the size of the airflow provided to the blowing nozzle 61, and the first solenoid valves of at least two feeding modules are configured with the same structure. The blowing nozzles 61 on at least two feeding shells 19 are controlled by the same first electromagnetic valve, that is, the airflow size blown out by the blowing nozzles 61 on at least two feeding shells 19 can be adjusted by adjusting the opening and closing degree of one first electromagnetic valve, so that the airflow size blown out by the air nozzles can blow the material stuck in the material pipe, move the material in the material pipe, speed up the speed of the material moving in the material pipe, and avoid the situation where the material is blown away on the conveying trough 21 due to excessive airflow. Therefore, the number of first electromagnetic valves that need to be adjusted is reduced, the time for adjusting the feeding speed of the feeding module is effectively reduced, and the convenience of adjusting the feeding module is improved.

[0108] In the second embodiment, at least two first solenoid valves are provided, and at least one first solenoid valve corresponds to the blowing nozzles 61 connected to at least two feeding modules. All blowing nozzles 61 connected to the same first solenoid valve are used to blow toward materials of the same specification, and different first solenoid valves can operate independently to blow toward materials of different specifications. That is, when the materials conveyed by the multiple feeding modules on the feeding device are different, all feeding modules conveying materials of the same specification have the same first solenoid valve controlling their blowing nozzles 61, so that the airflow size suitable for conveying materials of the same specification can be uniformly regulated, further improving the convenience of debugging the feeding module. It should be noted that the same specification is not only the same product model in a narrow sense, but also includes the situation that the product's appearance and weight are basically the same. It can be understood that even if the product model is different, but the weight is the same, the maximum static friction that it needs to overcome will be the same. At the same time, because the appearance and contour are basically the same, the windward area affected by the airflow is also basically the same. Therefore, it can be moved and conveyed in the material pipe at a basically the same moving speed under the premise of the same airflow size, and will not be blown away by the airflow from the material pipe after moving to the conveying trough 21. In other embodiments, the material conveyed by the feeding modules in the feeding device may have only one size, and in this case, the air nozzles on all the feeding modules are connected to the same first solenoid valve.

[0109] The accommodating space 13 can accommodate material pipes of various specifications, and the material pipes can store materials of various specifications. The blowing assembly 600 also includes a first vent pipe, and the first solenoid valve is connected to the blowing nozzle 61 through the first vent pipe. The first vent pipe and the blowing nozzle 61 are detachably installed so that multiple first solenoid valves can form different combinations with multiple air nozzles, and multiple air nozzles corresponding to materials of the same specification are connected to the same first solenoid valve. That is, there are two arrangement situations. In the second embodiment, the feeding modules for conveying materials of the same specification are arranged adjacent to each other, so as to be installed in a concentrated manner on the feeding device, and different conveying areas can be divided in the feeding module according to the different conveying materials, wherein the blowing nozzle 61 in a conveying area is connected to the same solenoid valve through the first vent pipe. Specifically, the left and right sides of the feeding shell 19 are provided with first avoidance holes 191 arranged opposite to each other, and the first solenoid valve is arranged in a feeding shell 19 in the conveying area. The first vent pipe passes through the first avoidance hole 191 to connect the blowing nozzle 61 and the first solenoid valve located in different feeding modules. Integrating the first solenoid valve and the first ventilation pipe in the feeding shell 19 helps to reduce the volume of the feeding device in the front-to-back direction. In the third real-time mode, the feeding modules for conveying materials of the same specifications are not arranged in a clustered manner on the feeding device, that is, according to the actual conveying requirements, the feeding modules for conveying materials of different specifications are mixedly arranged on the feeding modules so as to be able to convey materials of multiple specifications to a preset area at the same time. At this time, the rear end plate of the feeding shell 19 is provided with a second avoidance hole 192, the first solenoid valve is arranged outside the feeding shell 19, and the first ventilation pipe passes through the second avoidance hole 192 to connect the first solenoid valve and the blowing nozzle 61 arranged in the feeding shell 19. In other embodiments, it can also be that when the feeding modules are arranged in a clustered manner, the feeding shell 19 begins to have a second avoidance hole 192, and the first solenoid valve is arranged on the outside of the feeding shell 19.

[0110] In the second embodiment, a supporting module is further provided in the feeding shell 19, and the supporting module includes a supporting member (i.e., the front supporting block 41 and / or the rear supporting block 31) and a supporting cylinder (i.e., the front supporting driving member 42 and / or the rear supporting driving member 32) for driving the supporting member to move. The supporting member has a supporting position and a pipe withdrawal position. At the supporting position, the supporting member moves into the accommodating space 13 to lift the material pipe in the accommodating space 13. At the pipe withdrawal position, the supporting member moves out of the accommodating space 13. The supporting module includes a second solenoid valve for controlling the supporting cylinder. The number of the second solenoid valves corresponds to the number of the first solenoid valves. The supporting member connected to the same second solenoid valve lifts material pipes loaded with materials of the same specifications, and different second solenoid valves can operate independently to lift material pipes loaded with materials of different specifications. In the feeding module, when the supporting member moves out of the accommodating space 13, the support received by the material pipe in the accommodating space 13 is unbalanced, and the material pipe will fall out of the accommodating space 13. After the material pipe falls out of the accommodating space 13, the supporting member moves back to the accommodating space 13 to support the material pipe newly placed in the accommodating space 13, thereby realizing automatic tube replacement of the feeding module. Since in the feeding device, the feeding modules that convey materials of the same specifications have similar conveying rates and similar frequencies of replacing material pipes, a second solenoid valve can be used to control the synchronous movement of the supporting members in multiple feeding modules, thereby realizing synchronous tube withdrawal of the feeding modules that convey materials of the same specifications. This setting helps to further reduce the volume occupied by a single feeding module in the feeding device, so that more feeding modules can be installed. In other embodiments, a second solenoid valve can also be provided in a feeding module.

[0111] In the second embodiment, the feeding device is provided with a second vent pipe connecting the supporting cylinder and the second solenoid valve located in another feeding shell 19, and the left and right sides of the feeding shell 19 are provided with a third avoidance hole 193 arranged relatively, and the third avoidance hole 193 avoids the second vent pipe. The second solenoid valve and the second vent pipe are arranged and integrated in the material shell, which helps to further reduce the volume of the feeding device in the front and rear directions. Further, the blowing assembly 600 is arranged at the rear end of the feeding shell 19, the supporting cylinder and the second solenoid valve are both arranged at the rear end of the feeding shell 19, and the first avoidance hole 191 and the third avoidance hole 193 are configured as the same structure, that is, when the feeding module is clamped on the feeding device, it is convenient to adapt and connect the first solenoid valve and the second solenoid valve together with multiple feeding modules, which helps to improve the convenience of assembling adjacent feeding modules. In other embodiments, the third avoidance hole 193 and the second avoidance hole 192 can also be configured as the same structure, that is, the second solenoid valve and the first solenoid valve are both arranged on the outside of the feeding shell 19.

[0112] Furthermore, the feeding module also includes a material trough arranged in the feeding shell 19. The material trough is arranged above the accommodating space 13 and extends in the up and down directions. The preparation space 16 in the material trough is connected with the accommodating space 13. The preparation space 16 is used to accommodate a material pipe with feeding. The feeding module is also provided with a limiting device. The limiting device includes a limiting cylinder and a limiting member 43. The limiting member 43 is arranged at the bottom of the material trough. The limiting cylinder can drive the limiting member 43 to move in or out of the preparation space 16. When the limiting member 43 is located in the preparation space 16, it can limit the material pipe located at the bottom of the material trough. When the limiting member 43 moves out of the preparation space 16, the restriction on the material pipe located at the bottom of the material trough is released, so that the material pipe located at the bottom of the material trough falls into the accommodating space 13 and is lifted by the supporting member so as to be able to convey the material to the conveying trough 21. The limit cylinder is controlled by the third solenoid valve, and the number of the third solenoid valves corresponds to the number of the second solenoid valves. The limiter 43 connected to the same third solenoid valve limits the material pipes containing the same specification of materials, and different third solenoid valves can operate independently to limit the material pipes containing different specifications of materials. This can achieve synchronous tube replacement of the feeding modules that convey the same specification of materials, and further reduce the volume occupied by a single feeding module in the feeding device, so that more feeding modules can be installed. In other embodiments, a third solenoid valve can also be provided in a feeding module.

[0113] In the second embodiment, the feeding module also includes a vibration component 500, and the vibration component 500 includes a vibration driving component 51 arranged on the base 200. The opposite ends of the conveying trough 21 are respectively provided with a feed port 213 and a discharge port 214. The vibration driving component 51 is arranged close to the feed port 213 to vibrate the material pipe in the accommodating space 13. The material in the material pipe will be vibrated out of the material pipe to fall into the feed port 213 of the conveying trough 21. After the material falls into the feed port 213, the material is vibrated and moved at the feed port 213. Part of the airflow will flow out from the front end of the material pipe to have a thrust on the material at the feed port 213, thereby assisting the material to move toward the discharge port 214. It should be noted that, since materials of different specifications have different masses and sizes, the frequencies at which the materials can be moved in the material pipe are different, the frequencies at which the materials can be moved on the conveying trough 21 are different, and the vibration frequencies at which the material pipe can be shaken off the supporting member and the vibration frequencies at which the materials can be shaken off the conveying trough 21 are also different accordingly. Therefore, while the opening and closing degree of the first solenoid valve needs to be adjusted according to the specifications of the materials, the vibration frequency of the vibrating member also needs to be adjusted. Therefore, in a plurality of feeding modules in which the first solenoid valve is configured as the same structure, all vibration drive members 51 are electrically connected, and the vibration frequencies of the electrically connected vibration drive members 51 can be uniformly adjusted, that is, in the feeding modules conveying materials of the same specifications, the vibration frequencies of the vibration drive members 51 can be adjusted at the same time, which helps to reduce the time for adjusting the feeding speed of the feeding module and improves the convenience of adjusting the feeding module.

[0114] In the second embodiment, a fourth avoidance hole 194 is provided at the connection between the feeding shell 19 and the base 200, and the fourth avoidance hole 194 runs through the left and right sides of the base 200. The vibration driving member 51 is provided in the base 200, and the plurality of vibration driving members 51 are electrically connected through wires, and the wires can pass through the fourth avoidance hole 194 to connect the vibration driving members 51 in the feeding modules that convey materials of the same specifications. Further, when the feeding modules that convey materials of the same specifications are installed on the feeding device in a clustered manner, the feeding shell 19 has a shielding cover 195 arranged relative to the fourth avoidance hole 194. When two feeding modules are arranged adjacent to each other and convey materials of different specifications, the two shielding covers 195 are respectively covered on the adjacent fourth avoidance holes 194 on the two adjacent feeding modules to prevent dust from falling in. And when multiple feeding modules are installed on the feeding device, and only one feeding module conveys materials of different specifications from the materials conveyed by other feeding modules, the two fourth avoidance holes 194 of the feeding modules conveying materials of different specifications are both covered with shielding covers 195. In other embodiments, shielding covers 195 may not be provided. Specifically, when the feeding modules conveying materials of the same specifications are not arranged in a cluster on the feeding device, that is, when the feeding modules conveying materials of different specifications are mixedly arranged on the feeding module according to actual conveying requirements, the wire may pass through multiple feeding shells 19 while passing through the fourth avoidance holes 194.

[0115] In the second embodiment, the feeding module also includes a connecting assembly arranged on the feeding housing 19, the connecting assembly includes a front connecting piece and a rear connecting piece, the front connecting piece is arranged at one end of the feeding housing 19 close to the base 200, and the rear connecting piece is arranged at one end of the feeding housing 19 away from the base 200, and the front connecting piece and the rear connecting piece can connect two adjacent feeding modules. So that the feeding module can be installed together on the feeding device after the first solenoid valve, the second solenoid valve, the third solenoid valve and the vibration driving member 51 are combined and connected. Prevent the feeding module from shaking due to not being firmly installed on the feeding device, and avoid the feeding module that is not firmly installed from interfering with the normal operation of other normally installed feeding modules. Further, the front connecting piece and the rear connecting piece are both configured as bolts. In other embodiments, the connecting assembly can also connect two adjacent feeding modules by snapping.

[0116] In the fourth embodiment, the mounting seat 100 is provided with a receiving space 13, the receiving space 13 can accommodate a material pipe, and the receiving space 13 is provided with at least two, arranged in the left and right directions; the rear support assembly 300 is provided on the mounting seat 100, including a rear support block 31, the rear support block 31 extends into the receiving space 13 to support the rear end of the material pipe; the front support assembly 400 is provided on the mounting seat 100, including a front support block 41, the front support block 41 extends into the receiving space 13 to support the front end of the material pipe, the front support block 41 is lower than the rear support block 31, so that the The front end of the material pipe in the accommodating space 13 is tilted downward; the feeding assembly includes a vibration assembly 500 and a blowing assembly 600, the vibration assembly 500 includes a vibration driving member 51, which is used to vibrate the material pipe in the accommodating space 13 to move the material in the material pipe in the material pipe, the blowing assembly 600 includes a blowing nozzle 61 and a solenoid valve connected to the blowing nozzle 61, the blowing nozzle 61 is arranged relative to the rear end of the material pipe, and is used to blow air into the material pipe from the rear end of the material pipe to move the material in the material pipe out of the material pipe, and the solenoid valve is used to control the size of the airflow provided to the blowing nozzle 61. By arranging multiple accommodating spaces 13 in the left and right directions of the mounting seat 100, it is possible to realize the feeding operation of multiple material pipes at the same time, and when the thickness of the feeding device is appropriately increased, the feeding efficiency of the feeding device is improved, and the feeding device in the technical solution uses the vibration feeding and blowing feeding methods for the material pipe at the same time, so as to further improve the speed of the material in the material pipe moving out of the material pipe, thereby improving the feeding efficiency of the feeding device. It can be understood that when feeding the same number of material tubes at one time, the added thickness of the feeding device of the present technical solution is the sum of the widths of multiple material tubes. Compared with the thickness of all feeding devices that are clamped on the workbench and can only feed a single material tube, the feeding device in the present technical solution occupies less space, and when the clamping range of the workbench is limited, by clamping the feeding device in the present technical solution, the feeding efficiency of a single feeding device can be improved, thereby effectively improving the overall feeding efficiency.

[0117] In the fourth embodiment, the plurality of accommodating spaces 13 are all disposed on the left or right side of the mounting seat 100, the vibration driving member 51 and the electromagnetic valve are each provided with one, and the blowing nozzle 61 is provided with multiple, which are arranged one by one corresponding to the accommodating spaces 13. That is, the vibration of the same vibration driving member 51 in the plurality of material tubes causes the plurality of material tubes to be subjected to the same vibration frequency, and the strength of the airflow flowing through the plurality of material tubes is consistent, so as to realize synchronous feeding of the plurality of material tubes.

[0118] In the fourth embodiment, the mounting seat 100 is further provided with a material preparation space 16 extending in the up-down direction, the material preparation space 16 is connected to the upper end of the receiving space 13, the material preparation space 16 is used to store material pipes, the material pipe located in the receiving space 13 is defined as the first material pipe, and the material pipe located at the lowest end of the material preparation space 16 is defined as the second material pipe, the second material pipe can fall from the material preparation space 16 into the receiving space 13 to change into the first material pipe. The rear support assembly 300 includes a rear support driving member 32, the rear support blocks 31 extending into the plurality of receiving spaces 13 are the same rear support block 31, and the rear support driving member 32 drives the rear support block 31 to move into or out of the receiving space 13 along the front-rear direction. Furthermore, the front support block 41 and the rear support block 31 are spaced apart to form a drop tube gap 14 in the front-rear direction of the mounting seat 100, and the front support block 41 and the rear support block 31 are provided with a receiving space 13 above and a drop tube channel 15 below, and the receiving space 13, the drop tube gap 14 and the drop tube channel 15 are sequentially connected. When the rear support block 31 moves into the receiving space 13, the rear support block 31 lifts the rear end of the first material pipe, and when the rear support block 31 moves out of the receiving space 13, the rear support block 31 is separated from the rear end of the first material pipe and is located in the drop tube gap 14, so that the first material pipe falls into the drop tube channel 15 from the receiving space 13, and then the rear support block 31 moves back to the receiving space 13, and the second material pipe falls from the material preparation space 16, so that the first material pipe is lifted by the rear support block 31. Since the first material tubes in the multiple accommodating spaces 13 are supported by the same rear support block 31, the first material tubes that are fed synchronously will fall into the tube drop channel 15 at the same time, so as to replace the material tubes in batches. In other embodiments, it is also possible that there is no material preparation space 16 and rear support driving member 32, and the first material tubes in the accommodating space 13 are replaced by manual operation. In another embodiment, it is also possible that there are multiple rear support blocks 31, which are arranged one-to-one with the accommodating spaces 13, and there are multiple rear support driving members 32, which are arranged one-to-one with the rear support blocks 31, that is, the synchronously fed material tubes are replaced separately.

[0119] In the fourth embodiment, the mounting base 100 includes a group of material storage troughs 17, and the group of material storage troughs 17 includes two oppositely arranged material storage troughs 17, and the bottom walls of the material storage troughs 17 extend in the up and down directions. The opposite material storage troughs 17 enclose the material preparation space 16. There are at least two groups of material storage troughs 17, and they are arranged along the width direction of the mounting base 100. The group of material storage troughs 17 and the accommodating space 13 are arranged one by one. The feeding device also includes a limiting assembly, which includes a limiting member 91 and a limiting driving member 92 drivingly connected to the limiting member 91. The bottom wall of the material storage trough 17 is provided with an avoidance notch 171 at one end close to the accommodation space 13. The limiting member 91 is provided with a limiting protrusion corresponding to the avoidance notch 171. The limiting member 91 has a limiting position and a release position under the drive of the limiting driving member 92. In the limiting position, the limiting protrusion extends from the avoidance notch 171 into the material preparation space 16 and supports the bottom end of the second material pipe; in the release position, the limiting protrusion moves out of the material preparation space 16, and the limiting member 91 releases the restriction on the second material pipe. That is, when the first material pipe for synchronous feeding is changed, the second material pipe in the material preparation space 16 falls synchronously. The material preparation space 16 is arranged one-to-one with the accommodation space 13, which can prevent the material pipe from falling at a position without the accommodation space 13 and waste the material in the material pipe. Furthermore, two groups of limiting components are provided, and are arranged oppositely at the front and rear ends of the mounting seat 100 to support the front and rear ends of the second material tube respectively. In other embodiments, the material preparation space 16 may be enclosed by material preparation frames connected end to end. In another embodiment, a plurality of limiting members 91 may be provided, which can extend out and extend into the limiting notch 433, and a plurality of limiting driving members 92 may be provided, which are arranged one by one corresponding to the limiting members 91.

[0120] In the fourth embodiment, the front support assembly 400 includes a front support driving member 42. The front support blocks 41 extending into the plurality of the receiving spaces 13 are the same front support blocks 41. The front support driving member 42 drives the front support block 41 to move in the vertical direction and has a first position and a second position. In the second position, the front support block 41 is lower than the rear support block 31. In the first position, the upper side of the front support block 41 is close to the plane where the upper side of the rear support block 31 is located. Since the posture of the second material pipe in the material preparation space 16 is horizontal, and the posture of the first material pipe in the receiving space 13 is inclined during feeding, it is helpful to feed the material in the material pipe. In the process of the first material pipe changing from a horizontal posture to an inclined posture, the front end of the material pipe needs to move a long distance in the vertical direction. In order to make the front end of the first material pipe newly dropped from the material preparation space 16 move stably, the front support driving member 42 lifts the front end of the first material pipe and moves from the first position to the second position, which helps to make the front end of the material pipe move on a preset track. It can be understood that after the rear support block 31 moves out of the accommodating space 13, the front end of the first material tube is disengaged from the front support block 41 located at the second position, and then the front support block 41 moves to the first position to support the new first material tube. In other embodiments, the front support driving member 42 may not be provided, and a damping member is provided on the mounting seat 100, and the damping member can clamp the front end of the material tube, so as to achieve stable and slow movement of the front end of the material tube along a preset trajectory in the up and down direction.

[0121] In the fifth embodiment, at least one of the accommodating spaces 13 is provided on the right side of the mounting seat 100, and at least one of the accommodating spaces 13 is provided on the left side of the mounting seat 100. At least two of the air nozzles are provided, and at least two of the air nozzles are provided on the left and right sides of the mounting seat 100, respectively, to blow air to the material pipes located on the left and right sides of the mounting seat 100, and at least one of the solenoid valves controls the air nozzles provided on the left side of the mounting seat 100, and at least one of the solenoid valves controls the air nozzles provided on the right side of the mounting seat 100. At least two of the vibration driving members 51 are provided to respectively vibrate the material pipes located on the left and right sides of the mounting seat 100. That is, the vibration frequencies of the material pipe located on the left side of the mounting seat 100 and the material belt located on the right side of the mounting seat 100 may be inconsistent. In actual feeding, the optimal vibration frequency for vibrating the material out of the pipe and the size of the airflow in the pipe may be different depending on the diameter of the pipe and the size of the material in the pipe. Therefore, when the pipes or the materials in the pipes placed on the left side and the right side of the mounting seat 100 are different, the two vibration driving components 51 may operate at different vibration frequencies, and the two solenoid valves may also have inconsistent valve opening and closing degrees.

[0122] In the fifth embodiment, the rear support assembly 300 includes a rear support driving member 32, and two rear support blocks 31 are provided. One of the rear support blocks 31 supports the rear end of the material pipe on the left side of the mounting seat 100, and the other rear support block 31 supports the rear end of the material pipe on the right side of the mounting seat 100. There are two rear support driving members 32, which are arranged one by one corresponding to the rear support blocks 31 to drive the rear support blocks 31 to move into or out of the accommodating space 13 along the front and rear directions respectively. The front support assembly 400 includes a front support driving member 42. Two front support blocks 41 are provided. One of the front support blocks 41 supports the front end of the material tube on the left side of the mounting seat 100, and the other front support block 41 supports the front end of the material tube on the right side of the mounting seat 100. Two front support driving members 42 are provided, which are arranged one by one on the front support blocks 41. The front support driving member 42 drives the front support block 41 to move in the up and down direction and has a first position and a second position. In the second position, the front support block 41 is lower than the rear support block 31. In the first position, the upper side of the front support block 41 is close to the plane where the upper side of the rear support block 31 is located. Since the feeding speed of the material tube on the left side of the mounting seat 100 may be inconsistent with the feeding speed of the material tube on the right side of the mounting seat 100, the empty tube frequency of the material tube on the left side of the mounting seat 100 and the empty tube frequency of the material tube on the right side of the mounting seat 100 may be inconsistent. Separately performing the pipe withdrawal and pipe replacement operations on the left side of the mounting seat 100 and the material pipe on the right side of the mounting seat 100 helps to improve the feeding efficiency of the feeding device. In other embodiments, the rear support block 31 can be extended in the left-right direction and partially extend into the left and right sides of the mounting seat 100, that is, the material pipe on the left side of the mounting seat 100 and the material pipe on the right side of the mounting seat 100 are supported by the same rear support block 31; or; the rear support block 31 is arranged in a one-to-one correspondence with the accommodating space 13, and the rear support driving member 32 is arranged in a one-to-one correspondence with the rear support block 31, that is, the material pipe in each accommodating space 13 is supported by different rear support blocks 31, and the pipe withdrawal operation can be performed separately. In another embodiment, the front supporting block 41 may extend in the left-right direction and partially extend into the left and right sides of the mounting seat 100, that is, the material pipe on the left side of the mounting seat 100 and the material pipe on the right side of the mounting seat 100 are supported by the same front supporting block 41; or; the front supporting block 41 is arranged in a one-to-one correspondence with the accommodating space 13, and the front supporting driving member 42 is arranged in a one-to-one correspondence with the front supporting block 41, that is, the material pipe in each accommodating space 13 is supported by a different front supporting block 41, and the pipe replacement operation can be performed independently.

[0123] In the fifth embodiment, the mounting base 100 includes a substrate 18 and a base 200, the accommodating space 13 and the preparation space 16 are formed on the substrate 18, the base 200 is arranged at the front end of the substrate 18, and the upper side of the base 200 is formed with a left conveying area 215 and a right conveying area 216, the left conveying area 215 is correspondingly arranged on the left side of the substrate 18, the right conveying area 216 is correspondingly arranged on the right side of the substrate 18, and the left conveying area 215 and the right conveying area 216 are both provided with at least one conveying groove 21, and the vibration driving member 51 is both arranged at the rear end of the base 200, one vibration driving member 51 is arranged corresponding to the left conveying area 215, and the other vibration driving member 51 is arranged corresponding to the right conveying area 216. The material pipe in the accommodating space 13 on the left side of the substrate 18 is aligned with the conveying groove 21 on the left conveying area 215, specifically, the front end of the material pipe is in contact with the conveying groove 21 on the left conveying area 215; the material pipe in the accommodating space 13 on the right side of the substrate 18 is aligned with the conveying groove 21 on the right conveying area 216, specifically, the front end of the material pipe is in contact with the conveying groove 21 on the right conveying area 216. When the vibration driving member 51 vibrates, the end of the conveying groove 21 close to the base 200 vibrates, thereby driving the front end of the material pipe to vibrate, so as to drive the material in the material pipe to move out of the material pipe. It should be noted that the conveying groove 21 is arranged one-to-one with the accommodating space 13, that is, the material delivered by a material pipe is only transported in the corresponding conveying groove 21. In other embodiments, the left conveying area 215 and the right conveying area 216 may each be provided with only one conveying trough 21, and materials delivered by all material pipes on the left side of the base 200 are transported in one conveying trough 21, and materials delivered by all material pipes on the right side of the base 200 are transported in one conveying trough 21.

[0124] In the fifth embodiment, the base 200 further comprises at least two groups of photoelectric sensors 700, and at least two groups of photoelectric sensors 700 are arranged near the accommodation space 13, and the photoelectric sensors 700 include an exit sensor 71 and a receiving sensor 72 arranged opposite to each other, and at least one group of the exit sensor 71 and the receiving sensor of the photoelectric sensor 700 are arranged on the left and right sides of the left conveying area 215, and at least one group of the exit sensor 71 and the receiving sensor of the photoelectric sensor 700 are arranged on the left and right sides of the right conveying area 216. The photoelectric sensors 700 can sense the material at the front end of the material pipe to detect whether there is material in the material pipe being sent out from the front end of the material pipe. When no material is detected at the front end of the material pipe, the material stuck in the material pipe is blown out by increasing the vibration frequency and / or increasing the airflow in the material pipe. When no material is sent out from the front end of the material pipe after three repetitions, the material pipe in the accommodation space 13 is withdrawn and replaced. It should be noted that when a plurality of accommodating spaces 13 are provided on the left or right side of the base 200, a group of photoelectric sensors 700 are used to detect the material pipes in all the accommodating spaces 13 on that side, so as to reduce the installation volume of the base 200 by reducing the number of photoelectric sensor groups 700 installed. When only the front end of one material pipe is delivering material, the other material pipes need to wait until the front end of the material pipe can no longer detect the material, and then strengthen the vibration frequency and the airflow intensity in the material pipes for all material pipes to promote the material stuck in the material pipes to be separated from the material pipes, and then uniformly perform the pipe withdrawal and pipe replacement operations on the material pipes. In other embodiments, at least two photoelectric sensor groups 700 may be provided, and they are arranged one-to-one with the conveying troughs 21.

[0125] In the fourth embodiment, the mounting base 100 includes a substrate 18 and a base 200, the accommodating space 13 and the material preparation space 16 are formed on the substrate 18, the base 200 is arranged at the front end of the substrate 18, and a conveying groove 21 is formed on the upper side of the base 200, the conveying groove 21 is arranged in a one-to-one correspondence with the accommodating space 13, and a vibration driving member 51 is provided with one end close to the base 200 for vibrating all the conveying grooves 21, at least one group of photoelectric sensors 700 is provided on the base 200, and the outgoing sensor 71 and the receiving sensor 72 of at least one group of photoelectric sensors 700 are respectively arranged on the left and right sides of the base 200 to simultaneously detect the materials on all the conveying grooves 21 on the base 200.

[0126] In the first embodiment, the mounting base 100 is provided with a preparation space 16 for storing a plurality of material pipes, and the preparation space 16 extends in the up-down direction; the supporting module is provided on the mounting base 100, and includes a supporting member, and the supporting member is used to lift the material pipe, and a accommodating space 13 is constructed above the supporting member, the preparation space 16 is connected with the upper end of the accommodating space 13, the material pipe has a horizontal state in the preparation space 16, and the material pipe has an inclined state in the accommodating space 13; the limiting member 43, the limiting member 43 is provided with a limiting channel 431 extending in the up-down direction, and the upper end of the limiting channel 431 is connected to the preparation space 16, and the lower end of the limiting channel 431 passes through the accommodating space 13, and after the material pipe enters the limiting channel 431 from the preparation space 16, the horizontal state changes to the inclined state in the limiting channel 431. In the process of the material tube changing from a horizontal state to an inclined state, the distance moved in the up-down direction by one end of the material tube will be greater than that of the other end. In the process of the movement of the end with a larger moving distance, the material tube may be affected by the external environment, such as wind, vibration, collision, etc., so that the moving trajectory of the end with a larger moving distance has a tendency to deviate. In order to prevent the material tube from falling out of the supporting member or the material tube deviating from the preset position on the supporting member, a limit member 43 is provided. The limit member 43 is provided with a limit channel 431. After the material tube falls from the material preparation space 16, it moves in the limit channel 431 and falls into the accommodating space 13 in the limit channel 431. When the material tube has a tendency to deviate under the action of external force in the limit channel 431, the inner wall of the limit channel 431 abuts against the material tube to limit the moving trajectory of the material tube, so that the material tube can safely fall at the preset position of the supporting member after changing from a horizontal state to an inclined state. The feeding device can change the material pipe from a horizontal state to an inclined state without human assistance, and during the change process, the movement trajectory of the material pipe will not deviate. The material pipe can fall at a preset position on the supporting member, so that the feeding device can realize automatic loading, which helps to reduce labor costs.

[0127] In the first embodiment, the supporting member includes a front supporting block 41 and a rear supporting block 31. When feeding, the rear supporting block 31 is arranged close to the material preparation space 16, the front supporting block 41 is arranged away from the material preparation space 16, and the limiting member 43 is arranged close to the front end of the material pipe. That is, the inclined state of the material pipe is that the front end of the material pipe is lower than the rear end of the material pipe, and the front end of the material pipe will have a larger moving distance. The limiting member 43 is arranged close to the front end of the material pipe, that is, the limiting channel 431 is arranged close to the end of the material pipe with a larger moving distance, which helps to limit the end with a longer moving trajectory and prevent the moving trajectory of the material pipe from changing. In addition, by accurately limiting the end with a larger moving distance, the volume of the limiting member 43 can be reduced, and the consumables of the production of the limiting member 43 can be reduced. In other embodiments, the limiting member 43 can also extend along the length direction of the mounting seat 100 and be arranged relative to the middle section of the material pipe.

[0128] In the first embodiment, the limiting member 43 is arranged on the front supporting block 41, and the limiting member 43 includes a limiting piece 432, and the limiting piece 432 is provided with a limiting notch 433 opening upward, and the limiting channel 431 is formed in the limiting notch 433. That is, the limiting piece 432 extends in the up-down direction, and the top end of the limiting piece 432 extends into the material preparation space 16, so that the part of the structure of the material pipe at the bottom of the material preparation space 16 is located at the opening of the limiting notch 433, and the side wall of the limiting notch 433 abuts against the material pipe during the movement of the front end of the material pipe. In other embodiments, the limiting member 43 may also include limiting columns arranged on the left and right sides of the material pipe, and the limiting channel 431 is formed between the two limiting columns.

[0129] In the first embodiment, the supporting module further includes a front supporting driving member 42. When the front supporting driving member 42 drives the material pipe to move from the first position to the second position, the front end of the material pipe moves with the front supporting block 41 in the limiting channel 431 and gradually changes to an inclined state. The limiting channel 431 can limit the front end of the material pipe from moving in the left and right directions under the action of external force. In other embodiments, the front supporting driving member 42 may not be provided, and the front supporting block 41 is fixed in the second position. After the material pipe falls from the material preparation space 16, the rear end of the material pipe first contacts with the rear supporting block 31 and is lifted by the rear supporting block 31, and the front end of the material pipe moves in the limiting notch 433 until it contacts with the front supporting block 41.

[0130] In the first embodiment, both side walls of the limiting notch 433 are provided with abutting inclined surfaces 437, the two abutting inclined surfaces 437 are arranged opposite to each other, and the abutting inclined surfaces 437 extend obliquely from the opening of the limiting notch 433 to the inside of the limiting notch 433. It should be noted that the feeding device also includes a base 200 arranged at the front end of the mounting seat 100, and a conveying groove 21 is formed on the upper side of the base 200, and the conveying groove 21 can be used to convey the material removed from the material pipe. In the process of the front support block 41 moving from the second position to the first position, the limiting member 43 gradually extends into the material preparation space 16, at which time the material pipe in the material preparation space 16 slides and abuts against the abutting inclined surfaces 437, so that the material pipe in the material preparation space 16 is neatly arranged in the vertical direction, so that when the material pipe falls on the front support block 41 at the first position, the front end of the material pipe is located at a preset position so as to face the conveying groove 21. Furthermore, vertical surfaces 438 connected to the abutting inclined surfaces 437 are provided on both side walls of the limiting notch 433, and the vertical surfaces 438 are provided close to the front support block 41. The material pipe slides into the vertical surfaces 438 via the abutting inclined surfaces 437 in the limiting notch 433. At this time, the two side walls of the material pipe in the left and right directions abut against the two vertical surfaces 438 respectively, which helps to limit the front end of the material pipe. In other embodiments, when the front support driving member 42 is not provided, the front end of the material pipe falls into the limiting notch 433 and slides and abuts against the abutting inclined surfaces 437 to correct the moving track of the front end of the material pipe so that the front end of the material pipe can be arranged directly opposite to the conveying trough 21.

[0131] In the first embodiment, the limiting member 43 includes a mounting section 434 and a limiting section 436. At least part of the structure of the limiting section 436 extends out of the upper side of the front support block 41. The limiting notch 433 is provided in the limiting section 436. The mounting section 434 is connected to the front end surface of the front support block 41, or the mounting section 434 is connected to the rear end surface of the front support block 41. The mounting section 434 is used to enable the limiting section 436 to move relative to the front support block 41 to adjust the position of the limiting section 436 in the vertical direction. This is helpful to investigate the actual length of different material pipes and adjust the length of the limiting channel 431 extending out of the front support block 41 to adapt to material pipes of different specifications. Specifically, the mounting section 434 includes a third mounting hole 435 extending in the vertical direction. The front support block 41 is provided with a fourth mounting hole 411 corresponding to the third mounting hole 435. The fastener passes through the third mounting hole 435 and the fourth mounting hole 411 to connect the mounting section 434 and the front support block 41. In other embodiments, the mounting section 434 may be fixedly connected to the front support block 41, and the stopper 43 may be provided with a plurality of different stopper notch lengths, so that material pipes of different specifications can be adapted by replacing the stopper 43. In another embodiment, the fourth mounting hole 411 may extend in the up-down direction.

[0132] In the first embodiment, the supporting module further includes a slide rail assembly 44, which includes a slide groove 441 and a slider 442, wherein the slider 442 is slidably connected to the slide groove 441, the slide groove 441 is provided on the front supporting driving member 42 and extends in the up-down direction, and the slider 442 is provided on the front supporting block 41. When the front supporting driving member 42 lifts the front supporting block 41 in the up-down direction, the slide rail assembly 44 can further limit the moving track of the front supporting block 41, so that the movement of the front supporting block 41 in the up-down direction is more stable, and the front supporting block 41 can be prevented from shaking in the left-right direction or the front-back direction when moving in the up-down direction, which helps to prevent the material pipe from sliding off the front supporting block 41 and the front end of the material pipe from being unable to align with the conveying trough 21. Further, the front support block 41 includes a first plate section 412 and a second plate section 413 connected to each other, the first plate section 412 extends in the up-down direction and is arranged near the front side of the front support driving member 42, the front side of the front support driving member 42 is provided with a slide 441, a slider 442 is arranged on the side of the first plate section 412 near the front support driving member 42, the side of the first plate section 412 away from the front support driving member 42 is connected to the limiter 43, and the second plate section 413 is arranged near the upper end surface of the front support driving member 42 and is connected to the driving shaft of the front support driving member 42. When the second plate section 413 is lifted by the driving shaft, the slider 442 on the first plate section 412 cooperates with the slide 441 on the front support driving member 42 and moves along the extension direction of the slide 441, that is, the up-down direction, so that the limiter 432 on the first plate section 412 moves in the up-down direction. In other embodiments, the slide 441 can also be arranged on the mounting seat 100.

[0133] In the fourth and fifth embodiments, at least two material preparation spaces 16 are provided on one mounting seat 100, and at least two material preparation spaces 16 are provided on the same side of the mounting seat 100 in the left-right direction, and the limiting member 43 is provided with at least two limiting channels 431 in the left-right direction, and the limiting channels 431 are provided in a one-to-one correspondence with the material preparation spaces 16. That is, a plurality of limiting notches 433 are formed on a limiting piece 432, and when the feeding device simultaneously discharges a plurality of material pipes, a limiting piece 432 can limit the plurality of material pipes. In the first, second and third embodiments, there can also be only one material preparation space 16 on one mounting seat 100, and in this case, there is only one limiting notch 433 on the limiting piece 432.

[0134] Specifically, in the first embodiment, when only one side of the base plate 18 is provided with the accommodation space 13, there is only one limiting member 43, which is provided on the side of the mounting seat 100 having the accommodation space 13.
