Description

Technical Field

[0001] This invention relates to the field of automated production, and more particularly to a material conveying device. Background Technology

[0002] Currently, in the production line industry, material tray transfer is mainly carried out manually or by robotic arms. At present, domestic labor costs are rising year by year, and the material tray transfer process on the production line is characterized by high labor intensity, harsh working conditions, and low production efficiency, which does not meet the needs of modern automated production.

[0003] With the rapid development of mechanical automation technology, people have invented robotic arms to replace manual handling. Currently, the material tray transfer equipment used in production usually uses mechanical grippers to pick up and change trays. However, since each machine tool needs to be equipped with a robotic arm, its stability and efficiency in the material tray transfer process still need to be improved. Summary of the Invention

[0004] In order to overcome at least one of the defects described in the prior art, the present invention provides a material conveying device that ensures the efficiency and stability of the material conveying tray.

[0005] The technical solution adopted by this invention to solve its problem is:

[0007] In this way, after the material tray enters the feeding mechanism, it moves along the feeding direction to the lifting and circulating mechanism, and is transferred to the discharging mechanism together with the feeding layer of the lifting and circulating mechanism. The material tray is transferred by the cyclic rotation of the synchronous belt, which is smoother and more stable, ensuring the stability of the transported material tray. Moreover, multiple feeding layers are installed on the synchronous belt, so the transfer of the material tray is continuous and uninterrupted, which greatly improves the efficiency of feeding and meets the capacity requirements of modern automated production lines.

[0008] In some embodiments, the feeding layer further includes rollers, a plurality of rollers are rotatably mounted on the mounting strip, and the roller axes are respectively perpendicular to the feeding direction and the discharging direction; the feeding direction is defined as the direction of the feeding mechanism toward the lifting and circulating mechanism, and the discharging direction is defined as the direction of the lifting and circulating mechanism toward the discharging mechanism.

[0009] In some embodiments, the lifting and circulating assembly is further provided with a magnetic mounting plate that acts on a roller on the synchronous belt. The roller is made of a magnetic material or a magnetically adsorbent material. A gap is left between the magnetic mounting plate and the synchronous belt.

[0010] In some embodiments, the lifting and circulating mechanism further includes a drive assembly, which includes: a lifting motor, on the output shaft of which a first gear is provided; and a transmission gear set, which meshes with the first gear to drive the synchronous belts on the two sets of lifting and circulating assemblies to perform vertical circulating motion at the same speed but in opposite directions.

[0011] In some embodiments, the transmission gear set includes: a second gear meshing with a first gear, the number of teeth of the second gear being greater than the number of teeth of the first gear; a second gear, a third gear, and a fourth gear having the same number of teeth and meshing with each other; the third gear and the fourth gear respectively drive the lifting and circulating components so that the two oppositely arranged lifting and circulating components achieve synchronous and opposite-direction transmission.

[0012] In some embodiments, the feeding mechanism includes a first motor, a plurality of waiting positions and a pushing position arranged sequentially along the feeding direction, the first motor being used to move the material trays located at the waiting positions to the pushing positions one by one; the discharging mechanism includes a second motor, a receiving position and a plurality of discharging positions arranged sequentially along the discharging direction, the second motor being used to move the material trays located at the receiving positions to the discharging positions one by one.

[0013] In some embodiments, the waiting position is provided with a first fiber optic sensor and a feeding stop, both of which are connected to a first motor; the first fiber optic sensor is installed at the waiting position and is used to cooperate with the first motor and the feeding stop to control the progress of the material tray; the feeding stop blocks or releases the obstruction of the material tray movement under the control of the first motor.

[0014] In some embodiments, the feed stop includes a first cylinder, a second cylinder, and a baffle, wherein the first cylinder and the second cylinder are used to drive the baffle to block or release the material tray.

[0015] In some embodiments, the feeding mechanism further includes a pushing assembly electrically connected to the first motor. The pushing assembly includes: a lifting member for receiving a tray on the pushing position; a pushing cylinder for driving the lifting member to transfer the tray from the feeding mechanism to the lifting and circulating mechanism; and a lifting cylinder for driving the lifting member to move up and down in the vertical direction.

[0016] In some embodiments, the lifting and circulating mechanism further includes a receiving assembly electrically connected to a second motor. The receiving assembly includes: a receiving member for receiving a tray on the feeding layer; a receiving support located below the lifting and circulating mechanism, on which a second fiber optic sensor is fixedly mounted on the side away from the discharging mechanism; a jamming cylinder located on the receiving member near the lifting and circulating mechanism, on which a stop block is provided for abutting against the tray, the stop block being used to move the tray with the receiving member; and a receiving cylinder for driving the receiving member to transfer the tray from the lifting and circulating mechanism to the discharging mechanism.

[0017] In summary, the material conveying device provided by the present invention has the following technical effects:

[0018] 1) Compared with existing transfer tray technology, this invention uses gear meshing to drive the synchronous belt to circulate and transfer the tray. At the same time, it is equipped with a magnetic mounting plate to provide magnetic attraction to the rollers on the synchronous belt, making the rollers and synchronous belt more smooth and stable when transferring the tray. In addition, the design of the circulating transfer tray can improve the feeding efficiency and meet the efficiency requirements of modern automated production.

[0019] 2) The present invention also includes a roller that is rotatably connected to the mounting strip. The material tray rolls in and out of the lifting and circulating mechanism with the roller, thereby reducing friction. In addition, there is a gap between the surface of the magnetic mounting plate and the surface of the synchronous belt, that is, they do not contact each other, which can avoid friction caused by the contact between the synchronous belt and the magnetic mounting plate, ensuring smooth operation of the synchronous belt and making the material tray transport more stable.

[0020] 3) The present invention enables synchronous belts to move at the same speed but in opposite directions through the cooperation of transmission gear sets, ensuring the stability of the feeding layer and thus transferring the material tray. The gear meshing transmission makes the product compact, reliable in operation, and the gear transmission has strong stability, which improves the service life of the material conveying device.

[0021] 4) The feeding mechanism of this invention has multiple waiting positions, the discharging mechanism has multiple discharging positions, and the lifting and circulating mechanism has multiple feeding layers, which serve to accommodate and buffer the material trays, making full use of the spare space in the device.

[0046] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0049] Please see Figure 1 A material conveying device 100 includes: a lifting and circulating mechanism 400, which includes two sets of lifting and circulating components 41 arranged opposite to each other. Each lifting and circulating component 41 is provided with a synchronous belt 5 and a plurality of mounting strips 61 evenly spaced on the synchronous belt 5. The mounting strips 61 on the synchronous belt 5 of the two sets of lifting and circulating components 41 correspond one-to-one to form a feeding layer 6; a feeding mechanism 200, the end of which is connected to the lifting and circulating mechanism 400; and a discharging mechanism 300, the beginning of which is connected to the lifting and circulating mechanism 400. The feeding layer 6 moves up and down in a circular motion with the synchronous belt 5 to transfer the material tray of the feeding mechanism 200 to the discharging mechanism 300.

[0050] In this way, after the material tray enters the feeding mechanism 200, it moves along the feeding direction to the lifting and circulating mechanism 400, and is transferred to the discharging mechanism 300 together with the feeding layer 6 of the lifting and circulating mechanism 400. The material tray is transferred by the cyclic rotation of the synchronous belt 5, which is smoother and more stable, and can ensure the stability of the transported material tray. Moreover, multiple feeding layers 6 are installed on the synchronous belt 5, so the transfer of the material tray is continuous and uninterrupted, which greatly improves the efficiency of feeding and meets the capacity requirements of modern automated production lines.

[0051] Please see Figure 6 and Figure 8 The feeding layer 6 also includes rollers 62, and multiple rollers 62 are rotatably mounted on the mounting strip 61, with the axes of the rollers 62 being perpendicular to the feeding direction and the discharging direction, respectively; the feeding direction is defined as the direction of the feeding mechanism 200 toward the lifting and circulating mechanism 400, and the discharging direction is defined as the direction of the lifting and circulating mechanism 400 toward the discharging mechanism 300.

[0052] Understandably, since the axes of the rollers 62 are perpendicular to the feeding direction and the discharging direction respectively, the material tray can enter the lifting and circulating mechanism 400 from the feeding mechanism 200 and enter the discharging mechanism 300 from the lifting and circulating mechanism 400; and multiple rollers 62 are rotatably mounted on the mounting strip 61, so when the material tray enters and exits the lifting and circulating mechanism 400, it can roll on the rollers 62, thereby reducing the friction force of the material tray entering and exiting the lifting and circulating mechanism 400.

[0053] Please see Figure 6 and Figure 8 The lifting and circulating assembly 41 is also provided with a magnetic mounting plate 42, which acts on the roller 62 on the synchronous belt 5. The roller 62 is made of magnetic material or magnetic adsorption material; a gap is left between the magnetic mounting plate 42 and the synchronous belt 5.

[0054] It should be noted that each lifting and circulating assembly 41 has at least two columns 411, at least two first crossbeams 412 are connected between the two columns 411, and at least two connecting rods 51 are connected between the two columns 411. One connecting rod 51 has a pair of first synchronous pulleys 53, and another connecting rod 51 has a pair of second synchronous pulleys 52. The synchronous belt 5 is connected to the two connecting rods 51 through the first synchronous pulleys 53 and the second synchronous pulleys 52. In this embodiment, the inner side of the synchronous belt 5 rotates vertically downward and the outer side rotates vertically upward, thereby forming a complete synchronous belt 5. The body rotates vertically in a circular motion. The inner side of the synchronous belt 5 refers to the side of the synchronous belt 5 of one lifting and circulating assembly 41 that is close to the other lifting and circulating assembly 41. The outer side of the synchronous belt 5 refers to the side of the synchronous belt 5 of one lifting and circulating assembly 41 that is far away from the other lifting and circulating assembly 41. In addition, each lifting assembly in this embodiment is provided with at least one synchronous belt 5. It should be noted that the installation method of the lifting and circulating assembly 41 and the movement direction of the synchronous belt 5 are not limited to this. In other embodiments, they can be set according to specific needs, which will not be described in detail here.

[0055] To prevent the material tray from shaking significantly during the operation of the synchronous belt 5, in this embodiment, a magnetic mounting plate 42 acting on the roller 62 is vertically provided between the two columns 411. The magnetic mounting plate 42 is located on the outside of the mounting strip 61, and there is a gap between the surface of the magnetic mounting plate 42 and the surface of the synchronous belt 5. The outside of the mounting strip 61 refers to the side of the mounting strip 61 of one lifting circulation component 41 that is away from the other lifting circulation component 41. The magnetic mounting plate 42 is made of permanent magnet material, and the roller 62 is made of magnetic material or magnetic adsorption material. Magnetic adsorption material refers to materials that can be magnetically adsorbed, such as iron and nickel.

[0056] Specifically, during operation, the lifting and circulating mechanism 400 generates a magnetic attraction force on the roller 62 through the magnetic mounting plate 42, causing the synchronous belt 5 to tend to move towards the magnetic mounting plate 42. This tensions the synchronous belt 5, increasing the wrap angle of the synchronous belt 5 around the first and second synchronous pulleys 53 and 52, thus improving the stability of the synchronous belt 5's movement with the first and second synchronous pulleys 53 and 52. Furthermore, the tensioned synchronous belt 5 exhibits reduced swaying during movement, thereby reducing the swaying amplitude of the material tray during operation and ensuring the stability of the material tray's transport, preventing it from detaching from the roller 62 due to swaying. In this embodiment, the gap between the surface of the magnetic mounting plate 42 and the surface of the synchronous belt 5 prevents the synchronous belt 5 from contacting the magnetic mounting plate 42 and generating friction, ensuring smooth operation of the synchronous belt 5.

[0057] Please see Figure 6 and Figure 7The lifting and circulating mechanism 400 also includes a drive assembly 7, which includes: a lifting motor 71, on the output shaft of the lifting motor 71, a first gear 711; and a transmission gear set 70, which meshes with the first gear 711 to drive the synchronous belts 5 on the two sets of lifting and circulating assemblies 41 to perform vertical circulating motion at the same speed but in opposite directions.

[0058] Understandably, the power of the lifting motor 71 is transmitted to the first gear 711 through its output shaft. The transmission gear set 70 drives the synchronous belt 5 to move by meshing with the first gear 711. Furthermore, the synchronous belts 5 on the two sets of lifting components move in opposite directions and at the same speed. Therefore, the synchronous belt 5 can drive the adjacent mounting strips 61 on it to form a feeding layer 6 for carrying the material tray, thereby transferring the material tray.

[0059] Please see Figure 7 , Figure 8 and Figure 9 The transmission gear set 70 includes: a second gear 72 that meshes with a first gear 711, the number of teeth of the second gear 72 being greater than the number of teeth of the first gear 711; a second gear 72, a third gear 73, and a fourth gear 74 with the same number of teeth that mesh with each other; the third gear 73 and the fourth gear 74 respectively drive the lifting and circulating assembly 41 so that the two oppositely arranged lifting and circulating assemblies 41 achieve synchronous and opposite-direction transmission.

[0060] It should be noted that the transmission gear set 70 also includes a pair of driving pulleys 75, which are coaxially connected to the third gear 73 and the fourth gear 74 respectively; a pair of first driven pulleys 76, which are coaxially connected to the pair of driving pulleys 75 via a first belt 77; a pair of second synchronous pulleys 52, which are coaxially connected to the first driven pulleys 76 respectively; and a pair of first synchronous pulleys 53, which are coaxially connected to the second synchronous pulleys 52 via a synchronous belt 5. It should be noted that the arrangement of the transmission gear set 70 is applicable to this embodiment; in other embodiments, there are other different gear transmission relationships.

[0061] It should also be noted that, in the case of direct gear meshing, the design of the small gear driving the large gear is a speed reduction device, and this speed reduction device also has the advantage of saving effort. Therefore, the meshing of the first gear 711 and the second gear 72 can play the role of speed reduction and saving effort. The second gear 72, the third gear 73, and the fourth gear 74 have the same number of teeth and mesh with each other. The second gear 72 plays the role of transmitting power, while the third gear 73 and the fourth gear 74 play the role of transmitting power at the same speed but in opposite directions. Furthermore, the coaxial rotation and the synchronous belt 5 drive play the role of transmitting power and rotating at the same speed. Therefore, it can be deduced that the rotational speeds of the driving wheel 75, the first driven wheel 76, the second synchronous wheel 52, and the first synchronous wheel 53 are all the same. Through the cooperation of the above-mentioned transmission gear set 70, the synchronous belts 5 on the two sets of lifting components can perform vertical cyclic motion in opposite directions and at the same speed. The transmission gear set 70 has a compact structure, reliable operation, and improves the stability and service life of the material conveying device 100.

[0062] Please see Figure 2 The feeding mechanism 200 includes a first motor 23, a plurality of waiting positions 21 and a pushing position 22 arranged sequentially along the feeding direction. The first motor 23 is used to move the material trays located at the waiting positions 21 to the pushing positions 22 one by one. The discharging mechanism 300 includes a second motor 33, a receiving position 32 and a plurality of discharging positions 31 arranged sequentially along the discharging direction. The second motor 33 is used to move the material trays located at the receiving positions 32 to the discharging positions 31 one by one.

[0063] Specifically, both the feeding mechanism 200 and the discharging mechanism 300 include a frame 10. The upper part of the frame 10 consists of two second crossbeams 101 and several longitudinal beams 102 forming a hollow conveying platform. The lower part of the frame 10 is a first support 103. When the material tray is placed on the frame 10 of the feeding mechanism 200, the first motor 23 drives the material tray through several waiting positions 21 to reach the pushing position 22. When the material tray is placed on the frame 10 of the discharging mechanism 300, the second motor 33 drives the material tray through the receiving position 32 and several discharging positions 31 to leave the discharging mechanism 300.

[0064] Please see Figure 2 and Figure 3 The waiting position 21 is equipped with a first fiber optic sensor 24 and a feed stop 25, both of which are connected to the first motor 23. The first fiber optic sensor 24 is installed in the waiting position 21 and is used to cooperate with the first motor 23 and the feed stop 25 to control the progress of the material tray. The feed stop 25 blocks or releases the obstruction of the material tray movement under the control of the first motor 23.

[0065] It should be noted that in this embodiment, the first fiber optic sensor 24 is installed on the side of the waiting position 21. In other embodiments, different installation positions may be used as needed. When the first fiber optic sensor 24 detects that there is no tray on the corresponding waiting position 21, it converts it into an electrical signal and transmits it to the first motor 23. The first motor 23 controls the feed stop 25 on the previous adjacent waiting position 21 to release the tray, thereby moving the tray on the previous adjacent waiting position 21 to fill the gap and enter the waiting position 21. At this time, after the first fiber optic sensor 24 detects the tray, it converts it into an electrical signal and transmits it to the first motor 23. The first motor 23 controls the feed stop 25 on the previous adjacent waiting position 21 to block the tray from moving.

[0066] Please see Figure 3 , Figure 4 and Figure 5 The feed stop 25 includes a first cylinder 251, a second cylinder 253 and a baffle 252. The first cylinder 251 and the second cylinder 253 are used to drive the baffle 252 to block or release the material tray.

[0067] It should be noted that, in this embodiment, the feed stop 25 is located below the waiting position 21, and a fixing pin 256 is provided at the end of the feed stop 25 away from the baffle 252. The second cylinder 251 is connected to the feed stop 25 through the fixing pin 256, and the second cylinder 251 can move vertically along the fixing pin 256. The first cylinder 253 and the second cylinder 251 are connected by a first connecting rod 254, and the baffle 252 and the second cylinder 251 are connected by a second connecting rod 255. In other embodiments, different installation positions can be used as needed.

[0068] When the feed stop 25 performs its blocking action, the piston rod of the first cylinder 253 extends, driving the baffle 252 and the second cylinder 251 upward through the first connecting rod 254. The piston rod of the second cylinder 251 extends, driving the baffle 252 away from the feed stop 25 through the second connecting rod 255 and abutting against the material tray, thus blocking the material tray at the waiting position 21. When the feed stop 25 performs its unblocking action, the piston rod of the first cylinder 253 retracts, driving the baffle 252 and the second cylinder 251 downward through the first connecting rod 254, and the baffle 252 releases from contact with the material tray. The piston rod of the second cylinder 251 retracts, driving the baffle 252 to reset and approach the feed stop 25, thereby allowing the material tray to move through the waiting position 21.

[0069] Please see Figure 2 , Figure 10 and Figure 11The feeding mechanism 200 also includes a pushing assembly 8 electrically connected to the first motor 23. The pushing assembly 8 includes: a lifting member 83 for receiving the material tray on the pushing position 22; a pushing cylinder 82 for driving the lifting member 83 to transfer the material tray from the feeding mechanism 200 to the lifting and circulating mechanism 400; and a lifting cylinder 81 for driving the lifting member 83 to rise and fall in the vertical direction.

[0070] It should be noted that the lifting cylinder 81 is vertically installed in the feeding mechanism 200 and located below the pushing position 22. The piston rod of the lifting cylinder 81 is connected to the pushing cylinder 82. The piston rod of the lifting cylinder 81 is set vertically upward. The lifting cylinder 81 can drive the pushing cylinder 82 to move vertically upward. The lifting cylinder 81 is connected to the feeding mechanism 200 through a fixing plate 811. The parallel conveying platform of the pushing cylinder 82 is located below the pushing position 22. The piston rod of the pushing cylinder 82 is connected to a lifting member 83. The piston rod of the pushing cylinder 82 is set towards the feeding layer 6 adjacent to the pushing position 22. The pushing cylinder 82 can drive the lifting member 83 to move towards the feeding layer 6. The lifting member 83 abuts against the outer wall of the material tray so that the material tray is fixed on the lifting member 83 and moves with the pushing cylinder 82 and the lifting cylinder 81.

[0071] Thus, when the tray moves to the push position 22, the lifting cylinder 81 drives the push cylinder 82 to rise to the conveying platform of the feeding mechanism 200, so that the lifting plate engages with the tray. At this time, the push cylinder drives the tray to move toward the feeding layer 6 adjacent to the push position 22, so that the outer wall of the tray slides from the roller 62 into the feeding layer 6. Then, the lifting cylinder 81 drives the push cylinder 82 to move down and reset, and then the push cylinder 82 drives the lifting cylinder 81 to reset below the push position 22, thereby transferring the tray from the push position to the feeding layer 6 adjacent to the push position. Repeating the above steps can continuously transfer the tray.

[0072] Please see Figure 10 , Figure 12 and Figure 13 The lifting and circulating mechanism 400 also includes a receiving assembly 9 electrically connected to the second motor 33. The receiving assembly 9 includes: a receiving member 92 for receiving the material tray on the feeding layer 6; a receiving support 91 located below the lifting and circulating mechanism 400, on which a second fiber optic sensor 911 is fixedly mounted; a jamming cylinder 94 located on the receiving member 92 near the lifting and circulating mechanism 400, on which a stop block 941 is provided for abutting against the material tray, the stop block 941 for moving the material tray with the receiving member 92; and a receiving cylinder 93 for driving the receiving member 92 to transfer the material tray from the lifting and circulating mechanism 400 to the discharging mechanism 300.

[0073] It should be noted that the receiving cylinder 93 is located at the receiving position 32 of the discharging mechanism 300. The piston rod of the receiving cylinder 93 is set towards the lifting and circulating mechanism 400. The piston rod of the receiving cylinder 93 is connected to the receiving component 92. Therefore, the receiving cylinder 93 can drive the material tray on the receiving component 92 to move from the lifting and circulating mechanism 400 to the receiving position 32. The piston rod of the clamping cylinder 94 is set towards the feeding layer 6. The stop block 941 on the clamping cylinder 94 can abut against the outer wall of the material tray and fix the material tray on the receiving component 92.

[0074] In this way, when the second fiber optic sensor 911 senses the material tray, the receiving cylinder 93 drives the receiving component 92 to move below the adjacent feeding layer 6, and the clamping cylinder 94 drives the stop block 941 to rise and abut against the outer wall of the material tray. Then, the receiving cylinder 93 first drives the material tray to reset to the receiving layer, and then the clamping cylinder 94 drives the stop block 941 to reset and release it from the outer wall of the material tray, thereby moving the material tray to the feeding layer 6 adjacent to the receiving position 32. The above steps are repeated to continuously move the material tray.

[0075] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.

The feeding mechanism (200) is connected at its end to the lifting and circulating mechanism (400); The discharge mechanism (300) is connected at its beginning to the lifting and circulating mechanism (400); The feeding layer (6) moves up and down in a cycle with the synchronous belt (5) to transfer the material tray of the feeding mechanism (200) to the discharging mechanism (300); The feeding layer (6) also includes rollers (62), and a plurality of rollers (62) are rotatably mounted on the mounting strip (61); The lifting and circulating assembly (41) is also provided with a magnetic mounting plate (42), which acts on the roller (62) on the synchronous belt (5). The roller (62) is made of magnetic material or magnetic adsorption material. The magnetic mounting plate (42) is located outside the mounting strip (61), and there is a gap between the magnetic mounting plate (42) and the synchronous belt (5); During operation, the lifting and circulating mechanism (400) generates a magnetic attraction force on the roller (62) through the magnetic mounting plate (42), causing the synchronous belt (5) to have a tendency to move towards the magnetic mounting plate (42), thereby making the synchronous belt (5) taut. The feeding mechanism (200) includes a first motor (23), a plurality of waiting positions (21) arranged sequentially along the feeding direction, and a pushing position (22). The first motor (23) is used to transfer the material trays located at the waiting positions (21) to the pushing positions (22) one by one. The discharge mechanism (300) includes a second motor (33), a receiving position (32) arranged sequentially along the discharge direction, and a plurality of discharge positions (31). The second motor (33) is used to transfer the material trays located at the receiving position (32) to the discharge positions (31) one by one. The lifting and circulating mechanism (400) further includes a receiving assembly (9) electrically connected to the second motor (33), the receiving assembly (9) comprising: The receiving component (92) is used to receive the material tray on the feeding layer (6); A receiving support (91) is located below the lifting and circulating mechanism (400), and a second fiber optic sensor (911) is fixedly installed on the side of the receiving support (91) away from the discharging mechanism (300). A material clamping cylinder (94) is provided on the receiving part (92) on the side near the lifting and circulating mechanism (400), and a stop block (941) is provided on it for abutting against the material tray. The stop block (941) is used to make the material tray move with the receiving part (92). A receiving cylinder (93) is used to drive the receiving component (92) to transfer the material tray from the lifting and circulating mechanism (400) to the discharging mechanism (300); When the second fiber optic sensor (911) senses the tray, the receiving cylinder (93) moves the receiving component (92) to below the adjacent feeding layer (6), and the clamping cylinder (94) moves the stop block (941) up to abut against the outer wall of the tray. Then, the receiving cylinder (93) first moves the tray back to the receiving position (32), and then the clamping cylinder (94) moves the stop block (941) back to release it from abutment against the outer wall of the tray, thereby moving the feeding layer (6) adjacent to the receiving position (32) to the receiving position (32). The above steps are repeated to continuously move the tray.
