[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] It should be noted that if a directional indication is involved in the embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] Please refer to Figure 1 , Figure 3 and Figure 4 The flexible vibration plate feeding equipment 100 has a feeding station b and a feeding station a arranged at intervals along the horizontal direction. The flexible vibration plate feeding equipment 100 includes at least one feeding device 1, a feeding device 2 and a reflux device 3. The feeding device 1 is located at the feeding station a. The feeding device 1 includes a first mounting frame 11, a bearing bracket 12 and at least one vibration plate assembly 13. The vibration plate assembly 13 and the bearing bracket 12 are arranged at intervals along the longitudinal direction on the first mounting frame 11. The bearing bracket 12 is used for placing the flow tooling. The vibration plate assembly 13 is used to adjust the posture of the material and place the adjusted material on the first mounting frame 11. The feeding device 2 is placed on the circulation tooling on the supporting bracket 12, and is located at the feeding station b. The feeding device 2 includes a second mounting frame 21 and a picking portion 22 movably mounted on the second mounting frame 21 along the transverse direction. A picking area 24 is formed on the second mounting frame 21. The picking portion 22 is used to transfer the fully loaded circulation tooling in the loading device 1 to the picking area 24 for the processing equipment to pick up materials; the conveying path of the reflux device 3 passes through the feeding station b and the loading station a, and is used to move the circulation tooling at the loading station a out and send it back to the loading station a in an empty state.

[0023] In the technical solution of the present invention, the flow tooling is placed on the supporting bracket 12, and the vibration loading is performed through the vibration plate assembly 13. The insert material or the complex component material can be accurately and quickly adjusted to a predetermined posture, and the material is placed at a designated position on the flow tooling in a predetermined posture. Then the fully loaded flow tooling is transferred to the picking area 24 by the picking part 22, and the external processing equipment picks up the material. The flow tooling after picking up the material is returned from the feeding station b by the reflux device 3, so that it can return to the loading station a to complete the circulation of the flow tooling. The degree of automation is high. The loading device 1, the feeding device 2 and the reflux device 3 are divided into different modules. When different types or different quantities of materials need to be replaced, it can be achieved by splicing the loading device 1 or adding different numbers of vibration plate assemblies 13 to the loading device 1. The reflux device 3 does not affect the splicing of the loading device 1, and can ensure reflux, thereby reducing the debugging cost. It also adapts to changing production needs through its highly flexible adjustability.

[0024] The present invention does not limit the specific form of the vibration plate assembly 13, which can be a spiral vibration plate. The material is vibrated from the center of the vibration plate along the spiral path during the conveying process to adjust the posture, and finally output from the upper end of the vibration plate. In some implementations, please refer to Figure 3The vibration plate assembly 13 includes: a first vibration plate 131, a first visual detection component 132, a first transfer part 133 and a controller. The first vibration plate 131 is arranged on the first mounting frame 11, and is used to carry materials and adjust the posture of the materials by vibration; the first visual detection component 132 is arranged on the first mounting frame 11, and is used to detect the posture of the materials on the first vibration plate 131; the first transfer part 133 is located above the first vibration plate 131, and can be movably installed on the first mounting frame 11 in the horizontal, longitudinal and up and down directions; the controller is electrically connected to the first visual detection component 132 and the first transfer part 133, so as to control the first transfer part 133 to pick up and transfer the materials according to the detection result of the first visual detection component 132. The material is placed on the first vibration plate 131, which works at a set frequency. After each vibration, the first visual detection component 132 detects the current posture of the material on the first vibration plate 131, marks the material that meets the preset requirements, and the controller controls the first transfer unit 133 to pick up the marked material to the flow tooling. This structural form has efficient sorting and sorting functions, and can accurately and quickly arrange multiple inserts or complex components to the predetermined position.

[0025] It should be understood that the first transfer part 133 can pick up one material at a time or multiple materials at the same time, and the present invention does not limit this. The controller mentioned here can be the overall controller of the flexible vibration plate feeding device 100, or it can be a controller separately set on the first mounting frame 11 for this step.

[0026] It should be noted that the first transfer part 133 can be a structure such as a clamping claw or a suction cup, which is driven by a multi-axis driving component to achieve movement in multiple directions.

[0027] Considering that the accumulation of materials will affect the vibration sorting effect, in some embodiments, the vibration plate assembly 13 further includes a second vibration plate 134, which is located on the side of the first vibration plate 131. The second vibration plate 134 has a discharge end extending above the first vibration plate 131, and the second vibration plate 134 is used to transfer the concentrated multiple materials to the first vibration plate 131 through vibration dispersion. The operator or an external manipulator first piles a certain amount of materials on the second vibration plate 134, and the vibration of the second vibration plate 134 disperses the concentrated materials and transports them to the first vibration plate 131, thereby ensuring that the materials on the first vibration plate 131 are dispersedly arranged without accumulation.

[0028] It should be understood that the second vibration plate 134 is configured as a hopper loading vibration plate. The first vibration plate 131 is configured as a plane shaking vibration plate.

[0029] For further information, please refer to Figure 2, multiple vibration plate assemblies 13 are provided, and multiple vibration plate assemblies 13 are arranged on the first mounting frame 11 at intervals in the horizontal direction, and are used to adjust the postures of different types of materials respectively; the supporting bracket 12 can move in the horizontal direction to correspond to the multiple vibration plate assemblies 13 in sequence during the movement. At this time, each feeding device 1 can sort and feed multiple materials at the same time, and through the movable setting of the supporting bracket 12, multiple materials can be placed in the flow tooling in sequence during the movement of the supporting bracket 12 to complete the feeding action.

[0030] For example, three vibration plate assemblies 13 are arranged at intervals along the horizontal direction. Initially, the supporting bracket 12 corresponds to a vibration plate assembly 13 at the edge. After the first transfer part 133 completes loading, the supporting bracket 12 moves to another adjacent vibration plate assembly 13. After the corresponding first transfer part 133 completes loading, it continues to move to correspond to the last vibration plate assembly 13. After the last first transfer part 133 completes loading, the flow tooling completes the loading of all types of materials in the current loading device 1.

[0031] Furthermore, a plurality of support brackets 12 can be provided, and the plurality of support brackets 12 are spaced apart laterally and are movably provided laterally. Each support bracket 12 can pass through a plurality of vibration plate assemblies 13 in sequence, thereby realizing synchronous loading of a plurality of flow toolings and improving efficiency.

[0032] For further information, please refer again to Figure 1 , multiple feeding devices 1 are provided, and multiple feeding devices 1 are arranged in the horizontal direction, and the feeding devices 1 located at the edge are adjacent to the feeding device 2; each feeding device 1 also includes a material transfer part 14, which is movably installed in the horizontal direction to the corresponding first mounting frame 11, so as to be able to transfer the flow tooling on the adjacent feeding device 1 to the corresponding bearing bracket 12. Multiple feeding devices 1 pick up and transfer the flow tooling on the bearing bracket 12 in the adjacent device through the material transfer part 14. Thereby, the design of the external manipulator can be saved, making the overall layout more compact, while being able to adapt to splicing and facilitating rapid adjustment.

[0033] The present invention does not limit the structural form of the material moving part 14, which may be a suction cup structure, a clamping claw structure, etc. The material moving part may be driven to move by a cylinder, a screw structure, etc.

[0034] It should be noted that the flow tooling is not a conventional pallet, but a partition that is adapted to different types of materials. Different contour areas are set for different materials to ensure that the materials are transported in a fixed posture. The flow tooling has corresponding positioning, detection and other structures.

[0035] Please refer to Figure 4In some embodiments, the material picking part 22 includes a material picking body 221 and a lifting member 222. The material picking body 221 is movably installed in the horizontal direction and can move to protrude from the second mounting frame 21 in the horizontal direction; the lifting member 222 is movably installed to the material picking body 221 in the vertical direction, and the lifting member 222 is used to carry the flow tooling. The material picking body 221 drives the lifting member 222 to move horizontally, and the lifting member 222 can be located below the corresponding supporting bracket 12. The lifting member 222 can move up and down, thereby passing through the hollow position of the supporting bracket 12 to lift the flow tooling upward until it is separated from the supporting bracket 12. At this time, the material picking body 221 drives the lifting member 222 to move horizontally in the opposite direction to transfer the flow tooling to the material picking area 24.

[0036] In other embodiments, the material taking part 22 may also be a suction cup structure, a clamping claw structure, etc. In this embodiment, the material moving part 14 and the material taking part 22 have the same structure.

[0037] Considering the stability of the flow tooling when picking up materials at the feeding station b, in some embodiments, the feeding device 2 further includes a positioning bracket 23 provided in the picking area 24, and the picking portion 22 is used to place the flow tooling on the positioning bracket 23 for the processing equipment to pick up materials. The picking portion 22 is also used to remove the flow tooling on the positioning bracket 23 and transfer it to the side of the picking area 24 facing away from the feeding station a, so as to correspond to the reflux device 3. The positioning bracket 23 is arranged in the middle of the second mounting frame 21, or on the side of the second mounting frame 21 close to the first mounting frame 11. During the lateral movement of the picking portion 22, it first stays in the picking area 24, so that the flow tooling is fully loaded and fixed on the positioning bracket 23 to ensure its stability. After the external robot arm completes the material picking, the flow tooling can return to the picking portion 22 and be driven to be separated from the positioning bracket 23, so as to facilitate the operation of the reflux device 3 to return the flow tooling.

[0038] It should be noted that the material taking part 22 may be configured as a structure in which a material taking body 221 and a lifting member 222 cooperate, and the lifting of the lifting member 222 is used to lift and take the material and to place the flow tooling. The positioning bracket 23 may also be designed to have a lifting function, and when the material taking part 22 stays in the material taking area 24, the positioning bracket 23 is lifted to take away the flow tooling, and is kept at this height for the processing equipment to take the material, and after the material taking is completed, the positioning bracket 23 is dropped to put the flow tooling back on the material taking part 22.

[0039] In order to realize the reflux conveying function of the reflux device 3, in some embodiments, the reflux device 3 includes a third mounting frame 31, a plurality of conveyor belts 32 and a handling device 33. The third mounting frame 31 is adjacent to the first mounting frame 11 and is located on the side of the loading station a facing away from the feeding station b; the plurality of conveyor belts 32 extend laterally, and the plurality of conveyor belts 32 are correspondingly arranged on the first mounting frame 11 and the second mounting frame 21, and the conveying surfaces of the plurality of conveyor belts 32 are arranged flush; the handling device 33 includes two handling parts 331 movably arranged in the up and down directions, one of the handling parts 331 is arranged on the second mounting frame 21, and is used to transfer the flow tooling to the adjacent conveyor belt 32, and the other handling part 331 is arranged on the third mounting frame 31, and is used to transfer the flow tooling on the corresponding conveyor belt 32 to the corresponding supporting bracket 12. That is, the reflux device 3 is dispersed on the first mounting frame 11 and the second mounting frame 21. When multiple first mounting frames 11 are spliced, the conveyor belt 32 is spliced ​​accordingly, so that it can directly adapt to the longer distance transportation requirements. The adjustability of the conveyor belt 32 enables it to be quickly adjusted according to the specific size, shape and layout requirements of the splicing unit, without frequently replacing the entire module or performing complicated splicing and installation. The lifting and lowering of the transport part 331 can adapt to the height difference between the conveyor belt 32 and the material picking part 22.

[0040] Specifically, the transporting part 331 can be driven to move by a cylinder and a screw structure, and can rise to a specified position to receive the flow tooling. In one way, the transporting part 331 and the material picking part 22 are misaligned. When the transporting part 331 lifts the process tooling, the material picking part 22 can move laterally away from the corresponding area, so that the transporting part 331 can fall without interference. In another way, a stopper is provided at a corresponding position of the second mounting frame 21. During the process of lateral resetting of the material picking part 22, the flow tooling is stopped and separated from the material picking part 22, and naturally falls on the transporting part 331.

[0041] Considering the orientation, the transfer platform is located on the side of the first mounting frame 11. Therefore, the loading device 1 located at the edge can transfer the flow tooling on the corresponding transfer portion 331 to the support bracket 12 through the material transfer portion 14. In other embodiments, a mechanical arm can also be added to the third mounting frame 31 to move the flow tooling on the transfer portion 331 to the support bracket 12.

[0042] When the processing equipment takes the material, it may take away only part of the material due to a picking failure of the equipment or detection of material abnormality on the flow tooling. At this time, although the flow tooling has passed the material taking area 24, there is still material on it, rather than being in an empty state. In this case, if the flow tooling returns to the loading station a, it will cause material loading abnormality. Therefore, in some embodiments, please refer to Figure 5, the reflux device 3 also includes a discharge assembly 34, which includes a second visual inspection component 341, a second transfer part 342 and a controller. The second visual inspection component 341 is arranged on the third mounting frame 31, and is used to detect the amount of materials on the flow tooling on the corresponding conveying part 331; the second transfer part 342 is movably mounted to the third mounting frame 31 in the vertical direction, the horizontal direction and the longitudinal direction; the controller is electrically connected to the second visual inspection component 341 and the second transfer part 342, so as to control the second transfer part 342 to pick up and transfer materials according to the detection result of the second visual inspection component 341. That is, the second visual inspection component 341 is used to detect whether there is still material on the flow tooling on the conveying part 331. If there is no material, the flow tooling can return to the loading station a. If there is material, the material is removed by the second transfer part 342, so that the flow tooling remains in an empty state and returns to the loading station a, thereby ensuring the stability of the entire process.

[0043] It should be noted that the second transfer part 342 can be a structure such as a clamping claw or a suction cup, which is driven by a multi-axis driving component to achieve movement in multiple directions.

[0044] It should be noted that the controller mentioned here can be the main controller of the flexible vibration plate feeding device 100, or it can be a controller separately set on the third mounting frame 31 for this step.

[0045] Furthermore, the material discharging assembly 34 further includes a material guide pipe 343 and a material collection box 344. The material guide pipe 343 is disposed on the third mounting frame 31 and is tilted in the vertical direction. The upper end of the material guide pipe 343 is used to receive the material removed by the second transfer part 342; the material collection box 344 is disposed at the lower end of the material guide pipe 343 and is used to collect the material. The material guide pipe 343 is tilted so that the material can fall naturally into the material collection box 344 under the action of gravity along a certain tilt path, completing the collection of the material. The material guide pipe 343 can adapt to the height difference between the second transfer part 342 and the material collection box 344.

[0046] Furthermore, the upper end of the material guiding pipe 343 is trumpet-shaped, so as to facilitate receiving the material.

[0047] by Figure 1 Taking the embodiment of the present invention as an example, the flexible vibration plate feeding device 100 is used for feeding the injection molding machine, and the specific working process is as follows: The operator puts the punched insert materials into each second vibration plate 134, and the second vibration plate 134 vibrates to disperse the concentrated insert materials into the corresponding first vibration plate 131. The first visual inspection part 132 identifies the posture of the product in the first vibration plate 131 and marks the insert materials that meet the grabbing conditions. The first transfer part 133 moves to the visual marking position, grabs the insert materials that meet the conditions, and rotates them to the specified posture. At the same time, the first transfer part 133 moves to the top of the flow tooling position, puts the insert material into the flow tooling, drives the supporting bracket 12 to move, and transports the flow tooling to the position corresponding to the next first vibration plate 131, and successively realizes vibration, identification and grabbing, material placement to the flow tooling, and transmission to the next station until all product inserts are placed in the flow tooling. The picking part 22 will transfer the full tray of flow tooling to the picking area 24, corresponding to the injection molding machine robot picking position. After the injection molding machine robot finishes picking, the transport part 331 will transfer the flow tooling to the conveyor belt 32. Multiple conveyor belts 32 take over the transmission to send the flow tooling to the third mounting frame 31, and the second visual detection part 341 detects the quantity of materials on the flow tooling, and removes the excess materials. At this time, one cycle is completed, and the adjacent material transfer part 14 of the loading device 1 can be waited for to take away the empty flow tooling.

[0048] The technical solution of the present invention realizes the automatic loading of materials and can be applied to the loading of equipment such as injection molding machines and presses. The equipment combines the vibration plate technology with the adjustable conveying mechanism, which significantly improves the module splicing efficiency of existing feeding equipment and greatly reduces the commissioning and maintenance costs. The vibration plate has efficient sorting and sorting functions, and can accurately and quickly arrange multiple inserts or complex components to predetermined positions. The adjustability of the conveyor belt enables it to be quickly adjusted according to the specific size, shape and layout requirements of the splicing unit, without the need to frequently replace the entire module or perform complex splicing installation. This feature not only significantly improves the module splicing speed and reduces the commissioning cost, but also adapts to changing production needs through its highly flexible adjustability.

[0049] Please refer to Figure 6 to Figure 7 Based on the above-mentioned flexible vibration plate feeding device, the present invention proposes a control method for the flexible vibration plate feeding device, which specifically includes the following steps: S10: When the flow tool is at the loading station a, multiple loading devices 1 are controlled to work so as to load multiple materials onto the flow tool in sequence; It should be understood that the multiple feeding devices 1 are arranged side by side in the transverse direction and are close to each other, and the flow tooling can be transferred between two adjacent feeding devices 1 through the material transfer part 14 provided on the feeding device 1.

[0050] Specifically, each feeding device 1 performs screening and feeding of a single material, or screening and feeding of multiple materials.

[0051] For example, there are three feeding devices 1, each of which is used to feed three kinds of materials. After the flow tool passes through the first feeding device 1, it carries three materials. When it continues to pass through the second feeding device 1, it carries six materials. After passing through the third feeding device 1, it carries nine materials. The nine materials are independent of each other on the flow tool and do not contact each other.

[0052] S20: transferring the transfer tooling loaded with materials at the loading station a to the feeding station, and placing it in the material taking area 24 of the feeding device 2, so that the processing equipment can take materials; It should be understood that the main function of the flexible vibration plate feeding equipment is to organize and feed materials. The circulation tooling in the material picking area 24 should be full of materials. When the equipment is used to feed the injection molding machine, the circulation work here waits for the injection molding machine robot arm to pick up the materials.

[0053] It should be noted that the waiting time can be set, and after the set waiting time is met, it is assumed that the processing equipment has completed the material collection. The flexible vibration plate feeding device and the processing equipment can also be connected by electrical signal transmission, and the processing equipment sends an electrical signal to the flexible vibration plate feeding device after completing the material collection. A photoelectric sensor can also be set to detect that the mechanical arm of the processing equipment is away from the material collection area 24, and it is considered that the material collection has been completed.

[0054] S30: Control the reflux device 3 to remove the transfer tooling that has completed material collection in the material collection area 24 and send it back to the loading station a.

[0055] In the technical solution of the invention, when the flow tooling is at the loading station a, the flow tooling passes through multiple loading devices 1 to load multiple materials onto the flow tooling in sequence. The fully loaded flow tooling flows to the feeding station and can stay in the material taking area 24 of the feeding device 2 for the processing equipment to take materials. The reflux device 3 removes the flow tooling that has completed the material taking through the material taking area 24 and sends it back to the loading station a. During the entire processing process, the flow tooling starts from the loading station a, flows to the feeding station, and is transported back to the loading station a by the reflux device 3 after being taken by the equipment to realize the cycle. At the same time, multiple loading devices 1 can be spliced ​​to handle different types or quantities of materials to meet the changing production needs.

[0056] Further, based on the structural form of the feeding device 1, step S10 includes: S11: Control the material transfer part 14 in the loading device 1 away from the feeding station to transfer a transfer tool to the corresponding supporting bracket 12; It should be understood that, according to the return path of the flow tooling, the return device 3 will transfer the flow tooling to a position flush with the material transfer portion 14 after returning it from the feeding station, thereby adapting to the transfer height and transfer stroke of the material transfer portion 14 .

[0057] S12: Control the supporting bracket 12 to drive the transfer tooling to move through the plurality of vibration plate assemblies 13 in sequence so as to receive the corresponding materials; It should be understood that the movable stroke of the supporting bracket 12 needs to match the number of vibration plate assemblies 13 , and the supporting bracket 12 can stop at the side of the corresponding vibration plate assembly 13 during the lateral movement.

[0058] Specifically, when the supporting bracket 12 stays at each vibration plate assembly 13, its relative position with respect to each vibration plate assembly 13 can be consistent. Taking into account that the materials in each vibration plate assembly 13 are placed at different positions on the flow tooling and the material transfer setting procedure, when the supporting bracket 12 stays at the side of each vibration plate assembly 13, the installation area corresponding to the material of the vibration plate assembly 13 can be vertically opposite to the vibration plate assembly 13, and the previous material may be laterally offset from the vibration plate assembly 13.

[0059] S13: Control the material transfer part 14 in the adjacent loading device 1 to transfer the flow tooling after picking up materials to the corresponding supporting bracket 12, until the flow tooling completes picking up materials in the loading device 1 adjacent to the feeding station.

[0060] It should be noted that the supporting bracket 12 can move horizontally on the corresponding first mounting frame 11, and its movable stroke corresponds to the spacing of the vibration plate assembly 13 on the first mounting frame 11. In adjacent feeding devices 1, the transfer of the flow tooling is performed by the material transfer part 14. The material transfer part 14 of each feeding device 1 picks up the flow tooling at the previous workstation until it reaches the last supporting bracket 12 in the feeding path.

[0061] The transfer of the flow tooling at the loading station a can be completed by the splicing of the loading device 1 itself, without the need to add other structures, and the flow tooling moves in a unidirectional linear manner.

[0062] Further, in step S12, S121: Control the supporting bracket 12 to stop at a position corresponding to one of the first vibration plates 131 in the longitudinal direction; It should be understood that, taking the case where multiple first vibration plates 131, first mounting frames 11 and second mounting frames 21 are all arranged in the left-right direction, the supporting bracket 12 initially stays at the corresponding position of the first vibration plate 131 on the far right of the first mounting frame 11 on the rearmost side.

[0063] S122: marking the materials that meet the preset requirements detected by the first visual inspection component 132, and controlling the first transfer unit 133 to pick up the marked materials and transfer them to the transfer tooling on the supporting bracket 12; It should be understood that the first vibration plate 131 operates at a certain frequency and stops after each vibration. The first visual detection component 132 detects the posture of the material on the vibration plate. The preset requirements are different for different materials. The orientation of the material or the position of a certain surface can be used as an indicator of the preset requirements.

[0064] S123: Control the supporting bracket 12 to continue to move until it stops near the first vibrating plate 131 in another feeding device 1, and completes the corresponding material removal.

[0065] The supporting bracket 12 moves from right to left and stays on the side of the adjacent first vibration plate 131, repeating step S122 until the supporting bracket 12 moves to the leftmost first vibration plate 131 and completes material removal. The supporting bracket 12 stops moving and maintains the current position waiting for the feeding device 2 to take away the fully loaded flow tooling on it.

[0066] It should be understood that after the circulation tooling on the supporting bracket 12 on each first mounting frame 11 is removed, the supporting bracket 12 needs to be moved and reset to the initial state, waiting to receive new circulation tooling.

[0067] Further, based on the structural form of the feeding device 2, step S20 includes: S21: Control the material picking part 22 to move horizontally to extend into the loading station a, and pick up the transfer tooling loaded with materials at the loading station a; It should be understood that initially, the material taking part 22 is on the second mounting frame 21. When transfer is required, it needs to be moved laterally to protrude from the second mounting frame 21 until it extends into the supporting bracket 12 in the corresponding first mounting frame 11, thereby taking out the flow tooling.

[0068] S22: Control the material taking part 22 to drive the transfer tooling loaded with materials to move to the material taking area 24; After picking up the circulating tooling, the picking section 22 has two stop positions. The first stop position is the picking area 24, which is for facilitating the picking of the circulating tooling by the processing equipment.

[0069] It should be understood that the picking section 22 can always pick up the circulation tooling, and when in the picking area 24, the picking section 22 stops, and a corresponding positioning structure is provided thereon to ensure the fixation of the circulation tooling, or the picking section 22 can place the circulation tooling on a positioning bracket 23 located in the picking area 24.

[0070] S23 : After the material taking part 22 stays in the material taking area 24 for a preset time, the material taking part 22 is controlled to drive the flow tooling that has completed material taking to continue moving until it is away from the material taking area 24 .

[0071] It should be understood that the preset time is calculated based on the actual time of the processing equipment to take materials. The material taking part 22 drives the flow tooling away from the material taking area 24, which is convenient for the reflux device 3 to carry the flow tooling, and on the other hand, when the material taking part 22 is set to work in two alternating ways, it will not hinder the flow tooling behind from being sent in.

[0072] When the material taking part 22 includes a material taking body 221 and a lifting member 222, in step S21 Controlling the material taking body 221 to move horizontally so that the lifting member 222 is located below the flow tooling loaded with materials; The lifting member 222 is controlled to move upward to drive the flow tooling loaded with materials to separate from the corresponding supporting bracket 12 .

[0073] The transfer tooling is lowered or lifted by the up and down movement of the lifting member 222, and the height difference is utilized to complete the transfer and placement.

[0074] It should be understood that in step S23, when the lifting member 222 drives the circulating tooling to reach the material picking area 24, the lifting member 222 is controlled to fall and place the circulating tooling on the positioning bracket 23, and the lifting member 222 is kept stationary. After the preset time is met, the lifting member 222 is controlled to lift up the circulating tooling, and the material picking body 221 is controlled to move to drive the circulating tooling away from the material picking area 24.

[0075] Further, step S30 includes: S31: Control the reflux device 3 to move out the flow tooling that has finished taking materials through the taking area 24, and make it stay on the side of the loading station a facing away from the feeding station; Specifically, the transfer tooling is transported by the transporting portion 331 and the plurality of conveyor belts 32 and stays at the side of the loading station a facing away from the feeding station.

[0076] S32: Acquire the status of the flow tooling transferred by the reflow device 3; Specifically, the flow tooling is lifted up by the conveying part 331 and is located on the upper side of the third mounting frame 31. The second visual inspection part 341 is used to detect whether there is material on the flow tooling. If there is no material, the flow tooling is in an empty state. If there is material, the flow tooling is in a loaded state.

[0077] S33: If the transfer tooling is unloaded, the corresponding transfer tooling is sent back to the loading station a.

[0078] It should be understood that after the transfer tool returns to the loading station a, new materials will be placed at its corresponding position. If there are leftover materials on the transfer tool, new materials cannot be placed, causing process failure. Therefore, it is necessary to ensure that the transfer tool is sent back to the loading station a in an empty state through detection, so as to ensure the smoothness of the entire process.

[0079] S33': If at least one material remains on the flow tooling; S34': After controlling the discharge assembly 34 to remove the remaining materials on the circulation tooling, the corresponding circulation tooling is sent back to the loading station a; It should be understood that when the circulation tooling is in a loading state, the materials on the circulation tooling that are not taken away by the processing equipment are transferred to the collection box 344 for collection through the second transfer part 342, thereby achieving material discharge.

[0080] The materials stored in the collecting box 344 may be defective materials detected during the previous process of picking up materials, or they may simply be materials whose posture does not meet the requirements of picking up materials, so the materials need to be reclassified.

[0081] The specific steps are as follows: Obtaining the status of the material removed by the discharge assembly 34; If it is qualified material, it is put back into the corresponding feeding device 1; if it is defective material, it is discarded.

[0082] This avoids waste of materials. At the same time, the material inspection can share the equipment of other production lines without having to be set up separately in this device.

[0083] Further, in step S30, S31: Control the reflux device 3 to move the transfer tooling that has completed the material collection in the material collection area 24 to the side of the loading station a facing away from the feeding station; S32 : Control the material transfer unit 14 to transfer the corresponding transfer tooling to the loading station a and place it on the corresponding supporting bracket 12 .

[0084] Specifically, the transfer tooling is transferred from the upper layer to the lower layer through the transporting part 331 so that it can be transported by the conveyor belt 32. In order to ensure that the transfer tooling returns to the loading station a empty, the return device 3 will be tested only after the return is completed. Only when the material transfer part 14 receives the material transfer instruction, the material transfer part 14 will be controlled to move to place the corresponding transfer tooling on the corresponding supporting bracket 12. When the material transfer instruction is not received, the material transfer part 14 is in a standby state, and the waste discharge process may be carried out on the third mounting frame 31.
