Description

Technical Field

[0001] This invention relates to the field of tray-stacking machine technology, specifically a flexible feeding tray-stacking machine. Background Technology

[0002] The flexible feeding and tray-stacking machine is an industrial automation equipment that integrates vibration feeding, visual recognition and robot grasping technology. It is designed to solve the problem of accurate feeding and tray-stacking of bulk parts in multi-variety, small-batch production. Its core value lies in the fact that flexible feeding can quickly adapt to parts of different shapes and sizes, and production tasks can be switched without hardware replacement. The main components of the existing flexible tray-stacking machine include an operating table and its upper housing. The upper part of the operating table is equipped with a flexible feeding mechanism and a multi-directional adjustable conveying mechanism for picking up workpieces for conveying and stacking. On the side of the upper part of the operating table away from the flexible feeding mechanism, there is a feeding mechanism for feeding trays and a discharging mechanism for collecting trays that have completed the stacking work. A transport mechanism for conveying trays is provided between the feeding structure and the discharging mechanism.

[0003] Existing technology uses a flexible vibratory feeder for feeding, followed by visual recognition and coordinate positioning via a camera. Then, a multi-directional adjustable conveying mechanism picks up the workpiece based on the coordinates provided by the visual recognition. The conveying mechanism includes several gripping heads with suction cups at the bottom, each gripping workpiece individually. The conveying mechanism then moves the workpiece to the corresponding placement slot inside the pallet delivered by the transport mechanism. The gripping and placement process is repeated until the pallet is full of workpieces, at which point the pallet is transported to the unloading mechanism for unloading. However, existing handling mechanisms require repeated movement between the flexible vibratory feeder and the pallet. To avoid the pallet used for placing workpieces being affected by vibration, the flexible feeding mechanism and the transport mechanism used for transporting the pallet are respectively set on both sides of the operating table. This results in a long idle time for the handling mechanism, which reduces the conveying efficiency and pallet placement efficiency of the workpieces. In addition, the gripping components need to move frequently over a long stroke. During long stroke movements, the suction force of the handling mechanism on the workpieces may become unstable, and the workpieces may be affected by external factors such as equipment vibration, causing the gripped workpieces to fall off and resulting in workpiece damage.

[0004] Therefore, the present invention provides a flexible feeding tray machine that improves conveying efficiency and is less likely to cause damage to workpieces. Summary of the Invention

[0005] To address the problems of low workpiece conveying efficiency and tray-slab efficiency in existing technologies, a flexible feeding tray-slab machine has been designed.

[0006] The technical solution adopted by this invention to solve its technical problem is: a flexible feeding and tray-stacking machine, including an operating table and a flexible feeding mechanism for feeding workpieces fixedly connected to the upper end of the operating table. A vision inspection component is provided at the upper end of the flexible feeding mechanism. Two sets of multi-directionally adjustable conveying mechanisms are provided at the upper end of the operating table for gripping workpieces whose coordinates are provided by the vision inspection mechanism. A dual-station conveying assembly is fixedly connected below the conveying mechanism at the upper end of the operating table. The dual-station conveying mechanism includes two symmetrically arranged sets of third slide rails and staggered placement components at the upper end of the third slide rails, used to convey workpieces gripped by one set of conveying mechanisms. The staggered placement components facilitate continuous conveying of workpieces, and the other set of conveying mechanisms continuously trays the workpieces. The alternating dual-station conveying mechanism shortens the moving distance when gripping workpieces, thereby reducing the idle gap of the conveying mechanism and stabilizing the workpiece gripping process. It is used to convey workpieces gripped by one set of conveying mechanisms, facilitates continuous conveying of workpieces with the staggered placement components, and continuously trays the workpieces through the other set of conveying mechanisms. Furthermore, the dual-station conveying mechanism is equipped with a flipping adjustment mechanism. The flipping adjustment mechanism includes a mounting mold with a raised surface that is slidably connected to the third slide rail. The mounting mold has evenly distributed adjustment grooves at its upper end. A drive assembly is symmetrically arranged inside the mounting mold. Multiple clamping assemblies are connected to the drive assembly. Evenly distributed placement grooves are symmetrically opened at the upper end of the mounting grooves. The flipping adjustment mechanism is used to flip and adjust the reverse workpiece grasped by the conveying mechanism so that it is kept in the front position for tray placement. This allows the conveying mechanism to grasp both the front and reverse workpieces, thereby reducing the adjustment time when the conveying mechanism transports workpieces.

[0007] Furthermore, the dual-station conveying mechanism also includes limiting blocks at both ends of the third slide rail, sliding mounting components slidably mounted on the third slide rail, a third moving component fixedly connected to one side of the sliding mounting component for driving it to slide on the third slide rail, an installation mold fixedly connected to the upper end of the sliding mounting component, and the sliding mounting components are staggered at both ends of the two sets of third slide rails.

[0008] Furthermore, the mounting mold is fixedly connected to the upper end of the sliding mounting component. The mounting mold is slidably connected to the third slide rail through the sliding mounting component. The clamping assembly is located inside the adjustment groove. The clamping assembly can rotate inside the adjustment groove through the driving assembly to drive the reverse workpiece to rotate 180° so that it is adjusted to the front and placed in the placement groove. The placement groove matches the shape of the workpiece. The upper end of the placement groove is higher than the workpiece, and the upper edge is provided with a chamfer to guide the workpiece into the placement groove.

[0009] Furthermore, the driving assembly includes a first driving member disposed inside the mounting mold, a transmission member connected to the output end of the first driving member, a rotating shaft connected to the end of the transmission member away from the first driving member, the rotating shaft being rotatably connected to the mounting mold and located inside the upper protrusion of the mounting mold, and the clamping assembly being connected to the driving assembly via the rotating shaft.

[0010] Furthermore, the clamping assembly includes a rotating mounting component fixedly connected to a rotating shaft, a first clamping block protruding from one side of the rotating mounting component, a second driving component fixedly connected inside the mounting component, a sliding component fixedly connected to the output end of the second driving component, a second clamping block rotatably connected to the upper end of one side of the sliding component, a rotating rod rotatably connected between the second clamping block and the first clamping block, elastic protrusions on the clamping surfaces of the first clamping block and the second clamping block, two adjacent surfaces of the first clamping block and the second clamping block being clamping surfaces, the sliding component being slidably connected to the rotating mounting component, and the second clamping block being rotatably connected to the first clamping block through the rotating rod.

[0011] Furthermore, a multi-directional adjustment mechanism is slidably connected to one side of the conveying mechanism. The multi-directional adjustment mechanism includes a second slide rail fixedly connected to the upper end of the operating table via a fixed block, a second moving member disposed on one side of the second slide rail, a first slide rail slidably connected to the second slide rail, and a first moving member disposed at the upper end of the first slide rail. The conveying mechanism is slidably connected to the first slide rail on one side. The conveying mechanism performs multi-directional adjustment by using the first slide rail in cooperation with the first moving member and the second slide rail in cooperation with the second moving member, thereby gripping the workpiece on the flexible feeding mechanism.

[0012] Furthermore, the flexible feeding mechanism includes a feeding component fixedly connected to the upper end of the operating table and a flexible vibrating plate disposed on one side of the feeding component, which is used to transport the workpiece to the flexible vibrating plate through the feeding component, and then to disperse the workpiece evenly through the multi-directional vibration of the flexible vibrating plate.

[0013] Furthermore, the housing fixedly connected to the upper end of the operating platform is used to shield the processing area above the operating platform to prevent it from being affected by external factors. A transport mechanism for conveying pallets is fixedly connected to the side of the upper end of the operating platform away from the flexible feeding mechanism. A feeding mechanism for loading pallets and a unloading mechanism for unloading pallets are respectively provided on both sides of the transport mechanism. The bottom of the feeding mechanism and the unloading mechanism are fixedly connected to the operating platform through connecting plates and are located on both sides of the operating platform.

[0014] The beneficial effects of this invention are: (1) The flexible feeding and tray-stacking machine of the present invention realizes the alternating dual-station conveying of workpieces by means of a symmetrically arranged third slide rail and a sliding mounting component staggered on the third slide rail. A set of conveying mechanisms places the front workpiece into the placement slot opened in the mounting mold set on the sliding mounting component, while another set of conveying mechanisms takes out the workpiece in the other mounting mold for tray arrangement. This greatly reduces the empty movement distance between the feeding area of ​​the conveying mechanism and the tray, and improves the continuity of workpiece conveying and tray arrangement, thereby improving the workpiece conveying efficiency and the stability of workpiece conveying, and avoiding the occurrence of workpiece falling off and being damaged.

[0015] (2) The flexible feeding and tray-stacking machine of the present invention uses a clamping component inside a flipping adjustment mechanism set on a sliding mounting component to clamp the reverse workpiece picked up by the conveying mechanism. Then, the clamping component is driven by a drive component to rotate 180°, thereby causing the workpiece to rotate and flip, so that it is adjusted to the front position for subsequent tray-stacking. The flipping adjustment mechanism allows the conveying mechanism to pick up and transport both the front and flipped workpieces, thereby reducing the existing conveying mechanism's ability to pick up the front workpiece only and the need for multiple position adjustments to pick up the front workpiece, thus improving the workpiece picking efficiency of the conveying mechanism. In conjunction with the setting of a dual-station conveying mechanism, the conveying efficiency and tray-stacking efficiency of the workpiece are further improved. Attached Figure Description

[0019] To make the technical means, technical features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example: Figure 1 - Figure 21As shown, the flexible feeding and tray-stacking machine of the present invention includes an operating table 1 and a flexible feeding mechanism 3 for feeding workpieces 12 fixedly connected to the upper end of the operating table 1. A vision inspection component is provided on the upper end of the flexible feeding mechanism 3. Two sets of multi-directional adjustable conveying mechanisms 6 are provided on the upper end of the operating table 1 for gripping the workpieces 12 for which the vision inspection mechanism 4 provides coordinates. A dual-station conveying component is fixedly connected to the upper end of the operating table 1 below the conveying mechanism 6. The dual-station conveying mechanism 7 includes two sets of symmetrically arranged third slide rails 71 and placement components 75 staggered on the upper end of the third slide rails 71 for conveying the workpieces 12 gripped by one set of conveying mechanisms 6, and continuously conveying the workpieces 12 in conjunction with the staggered placement components 75. Then, the workpieces 12 are continuously trayed through the other set of conveying mechanisms 6. The conveying mechanism 6 shortens the moving distance when gripping the workpieces 12 through the dual-station alternating conveying setting of the dual-station conveying mechanism 7, thereby shortening the idle gap of the conveying mechanism 6 and stabilizing the workpiece gripping process.

[0021] Specifically, the flexible feeding mechanism 3 feeds the bulk workpieces 12 via the feeding component 31 using direct vibration. The workpieces 12 fall onto the flexible vibrating plate 32, where they are evenly dispersed by multi-directional vibration to avoid overlapping. The visual inspection mechanism 4 captures images in real time and uses AI algorithms to identify the position, orientation, and front and back of the workpieces 12, transmitting the coordinate information to the handling mechanism 6. Simultaneously, the loading mechanism 9 transports the pallet above the transport mechanism 10, where it is blocked by the limiting component and lifted by the lifting component for placement. The handling mechanism 6 performs multi-directional position adjustment via the first slide rail 51 and the first moving component 52, and the second slide rail 53 and the second moving component 54, picking up the positive workpieces 12 from the flexible vibrating plate 32. After adjusting the angle using an internal rotary motor, the workpieces are precisely placed in the placement component 75. Subsequently, the third moving component 74 drives the sliding mounting component 7. 3. The workpiece 12 is slidably conveyed along the third slide rail 71. Another set of conveying mechanisms 6, in conjunction with the multi-directional adjustment mechanism 5, picks up the workpiece 12 on the placement part 75 and places it onto the pallet. The dual-station conveying mechanism 7 adopts two sets of sliding mounting parts 73 staggered. When one set moves the workpiece 12 to the second set of conveying mechanisms 6, the other set slides to the first set of conveying mechanisms 6 to achieve alternating conveying, ensure continuous pallet placement, reduce the idle gap of the conveying mechanism 6, thereby improving conveying efficiency and stability, and preventing the workpiece 12 from falling off or being damaged due to vibration during long-term conveying. After a set of pallets is filled, the pallet can be lowered back above the conveying mechanism 10 by the retraction of the lifting part and conveyed to the unloading mechanism 11 for unloading. Then, the pallet can be loaded by the loading mechanism 9, and the subsequent pallet placement work can continue.

[0022] In this embodiment, the dual-station conveying mechanism 7 is provided with a flipping adjustment mechanism 8. The flipping adjustment mechanism 8 includes an installation mold 81 with a raised surface that is slidably connected to the third slide rail 71. The upper end of the installation mold 81 is provided with evenly distributed adjustment grooves 82. The drive assembly 83 is symmetrically arranged inside the installation mold 81. Multiple clamping assemblies 84 are connected to the drive assembly 83. The upper end of the installation groove is provided with evenly distributed placement grooves 85. The flipping adjustment mechanism 8 is used to flip and adjust the reverse workpiece 12 grasped by the conveying mechanism 6 so that it is kept in the front position for tray placement. This allows the conveying mechanism 6 to grasp both the front and reverse workpieces 12, thereby reducing the adjustment time when the conveying mechanism 6 is moving the workpiece 12.

[0023] Specifically, such as Figure 11 - Figure 21 As shown, the flipping adjustment mechanism 8 replaces the placement component 75, and the mounting mold 81 is used to connect to the sliding mounting component 73 to drive the workpiece 12 for conveying. The mounting mold 81 is fixedly connected to the upper end of the sliding mounting component 73 and is slidably connected to the third slide rail 71 through the sliding mounting component 73. The clamping assembly 84 is located inside the adjustment groove 82. The clamping assembly 84 can be rotated inside the adjustment groove 82 by the drive assembly 83 to drive the reverse workpiece 12 to rotate 180° to adjust it to the front and place it in another set of placement grooves 85. The groove 85 is matched with the shape of the workpiece 12. The upper end of the groove 85 is higher than the workpiece 12 and the upper edge is provided with a chamfer to guide the workpiece 12 into the groove 85. The flipping adjustment mechanism 8 enables the conveying mechanism 6 to not only transport and place the front workpiece 12, but also the back workpiece 12. This avoids the traditional conveying mechanism 6, which can only transport and place the front workpiece 12. Moreover, when picking up the front workpiece 12, multiple adjustments are required to pick up a set of workpieces 12. This further improves the conveying efficiency and plating efficiency of the workpiece 12.

[0024] In this embodiment, the dual-station conveying mechanism 7 also includes limiting blocks 72 provided at both ends of the third slide rail 71, sliding mounting parts 73 slidably mounted on the third slide rail 71, a third moving part 74 fixedly connected to one side of the sliding mounting part 73 for driving it to slide on the third slide rail 71, and mounting mold 81 fixedly connected to the upper end of the sliding mounting part 73. The sliding mounting parts 73 are staggered at both ends of the two sets of third slide rails 71.

[0025] Specifically, such as Figure 10 and Figure 11As shown, the limiting block 72 is used to restrict the sliding of the sliding mounting part 73 on the third slide rail 71. The third moving part 74 can be configured to drive the sliding mounting part 73 to move on the third slide rail 71 via a drag chain. The movement method of the drag chain is existing technology and will not be described in detail here. At the same time, the third moving part 74 can also be configured as any other structure that can achieve the same effect. By alternately conveying materials through the two sets of placement parts 75, continuous conveying and continuous traying of the workpiece 12 are achieved, and the idle gap of the conveying mechanism 6 is reduced. At the same time, under the action of the dual-station conveying mechanism 7, the pick-up time of the conveying mechanism 6 on the workpiece 12 is reduced, thereby increasing the stability of the conveying mechanism 6 in picking up and moving the workpiece 12. This avoids the problem that the workpiece 12 is prone to accidental fall due to vibration and other factors caused by long-term pick-up of the workpiece 12 for movement and traying, further improving the conveying efficiency and traying efficiency of the workpiece 12, while reducing the risk of damage to the workpiece 12.

[0026] In this embodiment, the driving assembly 83 includes a first driving member 831 disposed inside the mounting mold 81, a transmission member 832 connected to the output end of the first driving member 831, and a rotating shaft 833 connected to the end of the transmission member 832 away from the first driving member 831. The clamping assembly 84 includes a rotating mounting member 841 fixedly connected to the rotating shaft 833, a first clamping block 842 protruding on one side of the rotating mounting member 841, a second driving member 843 fixedly connected inside the mounting member, a sliding member 844 fixedly connected to the output end of the second driving member 843, a second clamping block 845 rotatably connected to the upper end of one side of the sliding member 844, a rotating rod 846 rotatably connected between the second clamping block 845 and the first clamping block 842, and elastic protrusions 847 provided on the clamping surfaces of the first clamping block 842 and the second clamping block 845.

[0027] Specifically, such as Figure 13 and Figure 16 - Figure 18As shown, the transmission component 832 can be configured as two sets of synchronous pulleys of the same size working in conjunction with a synchronous belt drive to transmit the rotation of the first driving component 831 to the rotating shaft 833, thereby driving the clamping assembly 84 to rotate. The first driving component 831 can be configured as a rotary cylinder capable of 180° rotation, used to drive the workpiece 12 to rotate and flip 180°. Simultaneously, the first driving component 831 and the transmission component 832 can also be configured as any other structure that achieves the same effect. The rotating shaft 833 is rotatably connected to the mounting mold 81 and located inside the upper protrusion of the mounting mold 81. The clamping assembly 84 is connected to the driving assembly 83 via the rotating shaft 833. The two adjacent surfaces of the first clamping block 842 and the second clamping block 845 are clamping surfaces. The sliding component 844 is slidably connected to the rotating mounting component 841. The second clamping block 84... 5. The first clamping block 842 is rotatably connected to the rotating rod 846. The elastic protrusion 847 can be made of rubber to prevent damage to the workpiece 12 when the first clamping block 842 and the second clamping block 845 clamp the workpiece 12. At the same time, it can increase the friction with the workpiece 12 and thus improve the clamping effect of the workpiece 12. The clamping force of the first clamping block 842 and the second clamping block 845 in combination with the elastic protrusion 847 on the workpiece 12 is sufficient to drive the workpiece 12 to perform a flipping operation. The first clamping block 842 is normally located inside the placement groove 85 to support one side of the workpiece 12. The second driving component 843 can be set as a cylinder drive, or it can be set as any other structure that can achieve the same effect. The driving component 83 and the clamping component 84 can also be set as any other structure that can achieve the same effect.

[0028] In this embodiment, the flexible feeding mechanism 3 includes a feeding component 31 fixedly connected to the upper end of the operating table 1 and a flexible vibrating plate 32 provided on one side of the feeding component 31. A set of conveying mechanisms 6 is slidably connected to a multi-directional adjustment mechanism 5 on one side. The multi-directional adjustment mechanism 5 includes a second slide rail 53 fixedly connected to the upper end of the operating table 1 through a fixing block, a second moving component 54 provided on one side of the second slide rail 53, a first slide rail 51 slidably connected to the second slide rail 53, and a first moving component 52 provided on the upper end of the first slide rail 51.

[0029] Specifically, such as Figure 3 - Figure 8As shown, the workpiece 12 is conveyed to the flexible vibratory feeder 32 by the feeding component 31. Then, the workpiece 12 is evenly dispersed by the multi-directional vibration of the flexible vibratory feeder 32. The conveying mechanism 6 is slidably connected to the first slide rail 51 on one side. The conveying mechanism 6 can perform multi-directional adjustment by cooperating with the first slide rail 51, the first moving component 52, and the second slide rail 53 and the second moving component 54 to grasp the workpiece 12 on the flexible feeding mechanism 3. The conveying mechanism 6 includes a Z-axis lead screw module, a Z-axis motor, a rotary motor, and a suction nozzle, etc., and can perform longitudinal movement and rotation of a single suction component. The multi-directional adjustment mechanism 5 also includes an X-axis linear motor and a Y-axis linear motor, which are used to cooperate with the first slide rail 51, the first moving component 52, the second slide rail 53, and the second moving component 54 to drive the conveying mechanism 6 to move in multiple directions. The flexible feeding mechanism 3, the vision inspection mechanism 4, the multi-directional adjustment mechanism 5, and the conveying mechanism 6 do not involve the core improvement technology of this application and are existing technologies, so they will not be described in detail here.

[0030] In this embodiment, the upper end of the operating platform 1 is fixedly connected to the housing 2, and the side of the upper end of the operating platform 1 away from the flexible feeding mechanism 3 is fixedly connected to the transport mechanism 10 for conveying pallets. The transport mechanism 10 is provided with a loading mechanism 9 for loading pallets and a unloading mechanism 11 for unloading pallets on both sides. The bottom of the loading mechanism 9 and the unloading mechanism 11 are fixedly connected to the operating platform 1 through a connecting plate and are located on both sides of the operating platform 1.

[0031] Specifically, such as Figure 1 - Figure 3 and Figure 9 As shown, the operating table 1 is used to install the internal components of the equipment, the housing 2 is used to shield the processing area above the operating table 1 to prevent it from being affected by external factors, the loading mechanism 9 is used to place the pallets to be processed and load them one by one onto the transport mechanism 10, the unloading mechanism 11 is used to collect the pallets after the workpieces 12 have been placed on the tray, the transport mechanism 10 uses an internally installed motor and conveyor belt group to transport the pallets, and uses a blocking cylinder and a lifting cylinder to lift the pallets transported to the appropriate position for placement. The implementation of the loading mechanism 9, the transport mechanism 10 and the unloading mechanism 11 is existing technology and will not be described in detail here.

[0032] Working principle: The flexible feeding mechanism 3 feeds the workpiece 12 to be processed. First, the loose material is put into the feeding component 31, and the feeding component 31 feeds the workpiece 12 directly into the flexible vibrating plate 32. Then, the flexible vibrating plate 32 generates multi-directional vibration to make the material evenly dispersed on the flexible vibrating plate 32, preventing the workpiece 12 from being stacked in an interlaced manner. Then, the visual inspection mechanism 4 takes real-time pictures of the parts in the tray, and the AI ​​algorithm identifies the position, direction and front and back sides, and transmits the coordinate information to the handling mechanism 6. At the same time, the tray is loaded onto the transport mechanism 10 by the loading mechanism 9 for transport. When it is transported to the designated position, it is blocked by the limiting component, and then lifted by the lifting component for subsequent tray placement. Next, the conveying mechanism 6, through the first slide rail 51 in cooperation with the first moving part 52 and the second slide rail 53 in cooperation with the second moving part 54, performs multi-directional position adjustment to pick up the workpiece 12 facing the front on the flexible vibrating plate 32. An internal rotary motor drives the bus to adjust its position, maintaining a certain angle for accurate placement inside the placement piece 75. Then, the third moving part 74 drives the sliding mounting piece 73 to slide along the third slide rail 71 to the other end. Next, another set of conveying mechanisms 6, in cooperation with the multi-directional adjustment mechanism 5, performs multi-directional adjustment to pick up the workpiece 12 on the placement piece 75 and transport it to the pallet on the transport mechanism 10 for pallet placement. Simultaneously, the sliding mounting piece 73 at one end of the other set of third slide rails 71 moves as the sliding mounting piece 73 containing the workpiece 12 moves. By staggering the two sets of sliding mounting parts 73, when the sliding mounting part 73 on which the workpiece 12 is placed moves to the second set of conveying mechanisms 6, the other set of sliding mounting parts 73 drives the placement part 75 to move to the first set of conveying mechanisms 6, realizing the alternating material conveying of the two sets of placement parts 75, thereby realizing continuous conveying and continuous traying of the workpiece 12, and reducing the idle gap of the conveying mechanism 6. At the same time, under the action of the dual-station conveying mechanism 7, the suction time of the conveying mechanism 6 on the workpiece 12 is reduced, thereby increasing the stability of the conveying mechanism 6 in suctioning and moving the workpiece 12, avoiding the problem that the workpiece 12 is prone to accidental fall due to vibration and other factors caused by long-term suction of the workpiece 12 for movement and traying, further improving the conveying efficiency and traying efficiency of the workpiece 12, while reducing the risk of damage to the workpiece 12. Simultaneously, by subtracting the placement component 75, a flipping adjustment mechanism 8 is provided on the sliding mounting component 73, allowing the conveying mechanism 6 to pick up the reverse workpiece 12 on the flexible vibratory feeder 32. The reverse workpiece 12 is then placed inside one of the two sets of placement slots 85 opened at the upper end of the mounting mold 81, near the flexible vibratory feeder 32. Next, the second driving component 843 drives the second clamping block 845 to move and rotate towards the workpiece 12, cooperating with the first clamping block 842 to clamp the workpiece 12. Then, the driving component 83 drives the clamping component 84 to rotate 180°, thereby allowing the workpiece to... The workpiece 12 is flipped into the second set of placement slots 85, thereby flipping the workpiece 12. At the same time, another set of front-facing workpieces 12 can be picked up and placed into the first set of placement slots 85, realizing the simultaneous conveying and palletizing of two sets of workpieces 12. This allows the conveying mechanism 6 to not only transport and palletize the front-facing workpieces 12, but also to transport and palletize the reverse-facing workpieces 12. This avoids the situation where the traditional conveying mechanism 6 can only transport and palletize the front-facing workpieces 12, and requires multiple adjustments to pick up a set of workpieces 12 when picking up the front-facing workpieces 12. This further improves the conveying and palletizing efficiency of the workpieces 12. Once a set of pallets is filled, the lifting mechanism can be retracted to lower the pallets back above the transport mechanism 10 for transport to the unloading mechanism 11 for unloading. Then, the loading mechanism 9 can be used to load the pallets, allowing the subsequent pallet placement process to continue.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Some non-core improvements have been described in a simplified manner, but this does not affect those skilled in the art from implementing the invention.

Claims

1. A flexible feeding and tray-loading machine, comprising an operating table and a flexible feeding mechanism for feeding workpieces fixedly connected to the upper end of the operating table, wherein a vision inspection component is provided at the upper end of the flexible feeding mechanism, characterized in that: The vision inspection component is used to identify the front and back of the workpiece. Two sets of multi-directional adjustable conveying mechanisms are set on the upper end of the operating table. Both sets of conveying mechanisms are located between the two stations of the dual-station conveying mechanism. They are used to grasp the workpiece with coordinates provided by the vision inspection component. One set of conveying mechanisms is close to the flexible feeding mechanism and is used to pick up the front workpiece from the flexible vibrating plate and place it in the placement piece on the dual station of the dual-station conveying mechanism. The other set of conveying mechanisms is close to the transport mechanism and is used to pick up the workpiece from the placement piece on the dual station of the dual-station conveying mechanism and place it on the tray on the transport mechanism. The dual-station conveying mechanism is fixedly connected to the upper end of the operating table below the conveying mechanism. The conveying mechanism shortens the moving distance when grasping the workpiece by alternating conveying between the two stations of the dual-station conveying mechanism, thereby shortening the idle gap of the conveying mechanism and stabilizing the workpiece grasping process. The dual-station conveying mechanism includes two sets of symmetrically arranged third slide rails on the operating table and placement components staggered on the upper end of the third slide rails. It is used to convey the front workpiece grasped by one set of conveying mechanisms, and to continuously convey the workpiece in conjunction with the staggered placement components. The workpiece is also continuously palletized by the other set of conveying mechanisms. Sliding mounting components are slidably installed on the third slide rails on the operating table, and the placement components are set on the sliding mounting components. The sliding mounting components staggered on the third slide rails drive the placement components to slide, thereby realizing the alternating dual-station conveying of the workpiece. The dual-station conveying mechanism is equipped with a flipping adjustment mechanism. The flipping adjustment mechanism located on the sliding mounting component includes a mounting mold with a raised surface that is slidably connected to the third slide rail. The upper end of the mounting mold has a uniformly distributed adjustment groove. The mounting mold is symmetrically equipped with a drive assembly. Multiple clamping assemblies are connected to the drive assembly. The upper end of the mounting groove has a uniformly distributed placement groove. The clamping assembly is located inside the adjustment groove. The clamping assembly can rotate inside the adjustment groove through the drive assembly to drive the reverse workpiece to rotate 180° so that it is adjusted to the front and placed in the placement groove. The flipping adjustment mechanism is used to flip and adjust the reverse workpiece grasped by the conveying mechanism so that it is kept in the front position for tray placement, thereby enabling the conveying mechanism to grasp both the front and reverse workpieces. A transport mechanism for conveying pallets is fixedly connected to the upper part of the operating platform away from the flexible feeding mechanism. On both sides of the transport mechanism, there are a feeding mechanism for loading pallets and a unloading mechanism for unloading pallets.
