Description

Technical Field

[0001] This invention relates to the field of electronic product technology, and in particular to an automatic feeding device for flexible products. Background Technology

[0002] In the automated assembly and production of modern electronic, electrical, and automotive parts, the precise insertion of metal terminals into plastic injection molded parts is a very common and critical process. This process requires extremely high alignment accuracy between the terminals and the pre-drilled holes or slots on the injection molded parts to ensure stable electrical connections and mechanical fastening.

[0003] Currently, the industry has developed relatively mature technical solutions for automated insertion operations of single-model products. The typical approach involves customizing dedicated support trays or fixtures for injection molded parts of specific dimensions, and installing high-precision mechanical positioning mechanisms (such as tapered pins and positioning blocks) at each station on the production line (especially the terminal insertion station) to fix and calibrate the trays. By ensuring the repeatability and accuracy of the tray's position, the consistent positioning of the injection molded parts it supports is indirectly guaranteed, thereby meeting the accuracy requirements for terminal insertion.

[0004] However, as products rapidly evolve towards smaller batches and more diverse varieties, production lines often need to be compatible with injection molded parts of various sizes and specifications. Against this backdrop, the aforementioned traditional solutions have revealed significant limitations.

[0005] Designing and manufacturing dedicated pallets for each size of injection molded part is difficult because different pallets have different sizes. It is also difficult to accurately position the corresponding pallet after the material is taken out, and it is also difficult to store the pallet of that size. Similarly, it is difficult to pick up and accurately position materials of specific sizes and shapes, which are eventually placed in the assembly area.

[0006] Therefore, a flexible product automatic feeding device is still needed to achieve precise positioning during the picking and handling process in order to solve the above problems. Summary of the Invention

[0007] The present invention provides an automatic feeding device for flexible products to solve the above problems.

[0008] The objective of this invention is achieved through the following technical solution: A flexible automated feeding device includes: A flexible feeding assembly is used to provide trays in batches and to collect the trays one by one after the material on the trays is removed. A pickup module for picking up and transferring materials from the tray; A precision positioning module, wherein the precision positioning module is provided with a precision positioning station for calibrating the position of the material picked up by the picking module; A flexible transfer component is used to transfer materials precisely positioned on the precision positioning module to the assembly station.

[0009] In one embodiment, the flexible feeding assembly includes a feeding bin and a lifting module.

The feeding bin includes: The bottom plate has a sliding connector on its top. A sliding plate, the bottom of which is connected to a slide rail, through which the sliding connector is slidably connected; The material feeding module includes: A lifting member and a lifting plate connected to the moving end of the lifting member, the lifting plate being located at the bottom of the tray and between adjacent sliding plates.

[0010] In one embodiment, the flexible feeding assembly further includes a feeding module disposed on top of the lifting module, the feeding module including at least one set of oppositely disposed flexible storage modules; The flexible storage module includes: a connecting plate and a bottom support connected to the bottom of the connecting plate. The bottom support has a supporting surface and extends toward the length direction of the tray to support the bottom of the tray in the length direction. The bottom of the connecting plate is slidably connected to the top of the support frame. A length screw assembly is also provided between the connecting plate and the support frame. The length screw assembly is used to drive the bottom support to slide relative to the tray along the length direction and to fit the outer side of the tray in the length direction through a length positioning surface perpendicular to the supporting surface. The top of the connecting plate is connected to a width propulsion member, and the moving end of the width propulsion member is connected to a width positioning plate. A width positioning surface is formed on the width positioning plate, and a width blocking member is also provided on the connecting plate.

[0012] In one embodiment, the bottom of the support frame is slidably connected to a length adjustment slide rail, and the bottom of the support frame is also connected to a length adjustment pusher, which is used to push the bottom of the support frame to move along the length direction of the material tray.

[0013] In one embodiment, the flexible feeding assembly further includes a receiving module located in the width direction of the tray. The receiving module includes two oppositely arranged storage plates with adjustable spacing, a push-pull member disposed between the storage plates and movable along the width direction of the tray, and a lifting member disposed on the moving path of the push-pull member. The push-pull component includes a push-pull slide rail and a hook part slidably connected to the top of the push-pull slide rail. The hook part can move along the height direction and hook the bottom of the material tray to be dragged between the storage plates. The storage plate is also provided with a one-way overlapping piece on the inner side. When the tray is lifted by the hanging part, the two sides of the tray first pass around the one-way overlapping piece and then overlap the one-way overlapping piece. The one-way overlapping piece is rotatably connected to the inner side of the storage plate and can be flipped towards the top along the rotation axis of the one-way overlapping piece and locked when the top surface is parallel to the horizontal direction, for stacking and storing the tray from bottom to top.

[0014] In one embodiment, the storage plate and the support frame are connected, and the storage plate adjusts synchronously when the support frame is adjusted.

[0015] In one embodiment, the pickup module is arranged on top of the workbench and connected in sequence as follows: An X-direction moving module, a Y-direction moving module, and a Z-direction moving module are provided. Each of the three modules includes a fixed rail and a sliding member that can slide relative to each other. The sliding member of the X-direction moving module is fixedly connected to the fixed rail of the Y-direction moving module. The moving end of the Y-direction moving module is fixedly connected to the fixed rail of the Z-direction moving module. The moving end of the Z-direction moving module is connected to a Z-direction rotating module. The Z-direction rotating module includes a rotating shaft and a pickup member connected to the end of the rotating shaft. The pickup component includes: a mounting bracket connected to the end of the rotating shaft, a connecting groove provided on the mounting bracket, a guide post connected in the connecting groove, a pickup frame slidably connected to the outer periphery of the guide post, the pickup frame moving along the axial direction of the guide post, and two pickup frames arranged opposite to each other.

[0016] In one embodiment, the pickup rack is provided with a drive slot, and a pneumatic drive component is connected to the pickup rack, with the moving end of the pneumatic drive component inserted into the drive slot.

[0017] In one embodiment, the precision positioning module includes a pushing module and a positioning platform. The pushing module is connected to the side wall of the positioning platform. The top of the positioning platform is divided into a connecting station for connecting the pushing module and a positioning station for determining the width of the material. The positioning station is provided with two sets of positioning surfaces, each including at least two mutually perpendicular planes for abutting the vertically inserted material from two horizontal directions. The pushing module includes a pushing block that can move horizontally. The bottom of the pushing block has a second driving groove for the moving end of the pushing module to be inserted, and a driving surface for driving the material to move in the width direction. The positioning surface opposite to the driving surface is a fixed width surface.

[0018] In one embodiment, the flexible transfer component includes a flexible clamp and a flexible moving disk. The moving disk can drive the clamp to clamp the material positioned by the precision positioning module and vertically remove it and place it into a preset assembly station.

[0019] Compared with the prior art, the beneficial effects of the present invention include at least the following: By setting up a flexible feeding component, a single batch of materials of the same group can be fed in batches. After the materials are picked up, the trays are collected in batches. The picking module can position the materials along their length during picking, and then place them onto the precision positioning module for positioning along their width. Finally, with the help of the flexible transfer component, they are accurately placed onto the assembly station. This not only meets the requirements for flexible loading and unloading of trays of various sizes, but also can precisely position and feed various different materials according to their own dimensions. It has high precision and a wide range of applications, making it highly practical. Attached Figure Description

Detailed Implementation

[0022] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0023] The terms used to express position and direction in this invention are illustrated with reference to the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0024] Reference Figure 1-12 This invention provides a flexible automated feeding device, comprising: The flexible feeding component 2 is used to provide material trays in batches and collect the trays one by one after the material on the trays is removed. The flexible feeding component 2 is located at the bottom of the workbench 1 and can move from bottom to top. Workers can feed materials in batches at the bottom of the workbench 1, and the flexible feeding component 2 can accurately position and feed various sizes of material trays and push them into the subsequent receiving bin after feeding.

[0025] Pick-up module 3 is used to pick up materials from the tray and transfer them. As a transfer component, the pick-up module 3 can pick up materials in the tray according to different lengths and transfer them to designated positions.

[0026] The precision positioning module 4 is equipped with a precision positioning station for calibrating the position of the material picked up by the pickup module 3. The precision positioning module 4 can also be called a transfer positioning module. Through the pickup module 3, the material is precisely positioned along its length. Specifically, when the pickup module 3 approaches the material, two relatively movable ends simultaneously clamp and position the material along its length. Then, the material is placed at the station of the precision positioning module 4, and its position is calibrated along its width. At this point, the material remains in a preset position in both the width and length directions, ready for installation or placement. Simply put, the coordinates of the material's position on the precision positioning module 4 at this time can be directly used as the direct docking object for the pin through simple transfer, without needing to obtain the material's spatial position again. This simple position calibration adapts to the insertion of materials of various lengths and widths.

[0027] Flexible transfer component 5 is used to transfer the precisely positioned material on the precision positioning module 4 to the assembly station.

[0028] The flexible transfer component 5 can transfer materials whose length and width are positioned horizontally on the precision positioning module 4 to the assembly station, where the robotic arm will precisely insert pins or terminals onto the materials. The flexible feeding component 2 of the precision positioning module 4 can adaptively adjust the length and width of the tray corresponding to different materials to achieve precise feeding and unloading. It is highly flexible and has a wider range of applications. It can complete the feeding of materials corresponding to various products without the need to replace different fixtures through complex tool changes.

[0029] Then, as the material passes through the pickup module 3 and the precision positioning module 4 in sequence, the pickup module 3 positions the material along its length, and the precision positioning module 4 simultaneously positions it along its width in the horizontal plane. The flexible transfer component 5 then holds and transfers the material to another position for connection with pins and terminals to be inserted. This system features a simple positioning method, eliminating the need for complex docking and position correction. It can pick up and position materials according to different shapes, making it more versatile and offering greater convenience and flexibility.

[0030] Preferably, the flexible feeding assembly 2 includes a feeding bin 6 and a lifting module 63. The feeding bin 6 is located at the bottom of the workbench 1 and can feed materials along a direction perpendicular to the vertical movement of the lifting module 63. The feeding bin 6 includes: The bottom plate 61 has a sliding connector on its top.

[0031] The sliding plate 62 has a slide rail connected to its bottom, through which the sliding connector is slidably connected; the lower base plate 61 can move relative to the sliding plate 62, and the lower base plate 61 can be used to place manually stacked material trays, and can be pulled out or pushed in along a straight line to facilitate manual loading.

[0032] The material feeding module 63 includes: A lifting member 631 and a lifting plate 632 connected to the movable end of the lifting member 631 are included. The lifting plate 632 is located at the bottom of the material tray and between adjacent sliding plates 62. The lifting plate 632 is inserted between the sliding plates 62, and the top center of each sliding plate 62 has a C-shaped frame. When the material tray is being fed, the lifting plate 632 simultaneously supports the bottom of the material tray. The lifting member 631 is a cylinder or an electric telescopic rod. Under the action of the lifting member 631, the material trays at the top can be picked up and isolated one by one, facilitating automatic feeding and lifting of the material tray's position.

[0033] Preferably, the flexible feeding assembly 2 further includes a feeding module 21, which is disposed on top of the lifting module 63, and the feeding module 21 includes at least one set of oppositely disposed flexible storage modules. The flexible storage module includes a connecting plate 231 and a bottom support 232 connected to the bottom of the connecting plate 231. The bottom support 232 has a supporting surface and extends along the length direction of the tray to support the bottom of the tray in the length direction. The bottom of the connecting plate 231 is slidably connected to the top of the support frame. A length screw assembly 234 is also provided between the connecting plate 231 and the support frame. The length screw assembly 234 is used to drive the bottom support 232 to slide relative to the tray along the length direction and to abut the outer side of the tray along the length direction through a length positioning surface perpendicular to the supporting surface. During operation, the tray is lifted from the middle position and reaches both sides of the bottom support 232. Then, the bottom support 232 can move along the length direction of the tray under the drive of the connecting plate 231. The tray is dragged and clamped by the bottom support 232, which gradually approaches from both sides. The lead screw assembly 234 includes a lead screw, a motor, and a slide rail. The end of the lead screw is connected to the motor, and the threaded part of the lead screw is connected to a plate 231.

[0034] The top of the connecting plate 231 is connected to a width pushing member 235, and the moving end of the width pushing member 235 is connected to a width positioning plate 236. A width positioning surface 2361 is formed on the width positioning plate 236. A width blocking member 237 is also provided on the connecting plate 231. The width blocking member 237 is used to cooperate in blocking the material tray that is pushed through the width positioning surface 2361. The width propulsion component 235 is, for example, an electric or pneumatic telescopic rod arranged laterally on both sides of the top of the connecting plate 231. The width positioning plate 236 has a width positioning surface 2361, which is perpendicular to the surface of the connecting plate 231 and located on both sides of the surface of the connecting plate 231. The surface of the width blocking component 237 is perpendicular to the width positioning surface 2361. During operation, the width propulsion component 235 drives the width positioning plate 236 to move gradually in the horizontal direction and cooperates with the width blocking component 237 to gather the material. This can center and position various material trays of different widths. After centering, it is convenient for the picking module 3 to identify the approximate position of the material on the two trays according to the preset coordinate system. Then, during picking, the centering gripper on the picking module 3 gathers the material, so that the roughly positioned material is accurately positioned in the length direction. In summary, the feeding module 21 can automatically and accurately position itself according to the length and width of the material tray, which makes it convenient for the subsequent picking module 3 to accurately pick up the material in the correct position and put it into the subsequent installation station.

[0035] Preferably, the width blocking member 237 is further connected to an avoidance propulsion member, the movable end of the avoidance propulsion member can move along the length direction of the tray, and the width propulsion member 235 is connected to the movable end of the avoidance propulsion member for avoiding the tray in the width direction. The width blocking member 237 is telescopic and is connected to the moving end of the avoidance pusher. The avoidance pusher can push the width blocking member 237 away from the width direction of the tray, so that the tray can leave the feeding position of the tray under the continued push of the width pusher 235. After the material is taken out, the remaining tray is pushed to one side. The avoidance pusher can be a cylinder or an electric telescopic rod. By setting the avoidance pusher, under the pushing operation of the original width pusher 235, not only can the width positioning be achieved, but the tray can also be easily emptied after the material is taken out, thereby achieving a high degree of automation. Moreover, under the action of the avoidance pusher, the placement position of the tray after being positioned will not be changed. The straight retraction method allows the tray to continue to be pushed out in a straight line according to the accurate positioning posture, so that the tray will not be jammed due to deviation and can be discharged smoothly.

[0036] Preferably, the bottom of the support frame 233 is slidably connected to a length-adjustable slide rail, and the bottom of the support frame 233 is also connected to a length-adjustable pusher, which is used to push the bottom of the support frame 233 to move along the length direction of the material tray. The bottom of the support frame 233 is slidably connected to the workbench 1, which allows for significant adjustment of the length of the supported tray. Once the spacing between a group of support frames 233 is adjusted, their positions are fixed. Subsequent adjustments only require changing the position of the connecting plate 231, eliminating the need for frequent adjustments to the spacing of the connecting plates 231 to accommodate longer overlaps, thus saving resources and offering a wide range of applications.

[0037] Preferably, the flexible feeding assembly 2 further includes a receiving module located in the width direction of the tray. The receiving module includes two oppositely arranged storage plates with adjustable spacing, a push-pull member 242 disposed between the storage plates and movable along the width direction of the tray, and a hook-drive member 243 disposed on the moving path of the push-pull member 242. The receiving module can be located directly behind the flexible assembly on the workbench 1. The storage plates 241 are two parallel plates used for stacking trays. The push-pull member 242 acts as a traction device, pulling the tray along a straight line between the storage plates 241. An overlapping metal sheet is formed between the storage plates 241, which can be supported by the two edges of the tray and moved linearly between the storage plates 241 under the action of the push-pull member 242. The hook-drive member 243 is, for example, a linear cylinder or a linear drive module.

[0038] The push-pull component 242 includes a push-pull slide rail 2421 and a hook part 2422 slidably connected to the top of the push-pull slide rail 2421. The hook part 2422 can move along the height direction and hook onto the bottom of the tray, pulling it between the storage plates 241. The push-pull component 242 includes a vertically placed cylinder for driving the hook part 2422 to move vertically, and also connected to a horizontal cylinder for driving the hook part 2422 hooked at the bottom of the tray after vertical movement, and pulling the tray along a straight line until it is finally received between the storage plates 241. The push-pull component 242 can pull the tray out vertically, and then the two sides of the tray slide on the support plates between the storage plates 241 before moving to... The storage plate 241 also has a one-way overlapping piece on its inner side. When the tray is lifted by the hook part 2422, the two sides of the tray first pass around the one-way overlapping piece and then overlap the one-way overlapping piece. The one-way overlapping piece is rotatably connected to the inner side of the storage plate 241 and can be flipped towards the top along the axis of rotation of the one-way overlapping piece. It is locked when the top surface is parallel to the horizontal direction, and is used to stack and store the tray from bottom to top. After the push-pull part 241 pushes and pulls horizontally, the one-way overlapping piece is vertically lifted to a certain height, raising the tray vertically. This causes the two ends of the tray to be squeezed around the bottom of the one-way overlapping piece, and then the two rear sides overlap the top of the one-way overlapping piece in the vertical direction to complete the material collection. One-way overlapping component is, for example, a one-way spring hinge. The tray is pushed from the bottom to the top. After the tray passes the one-way overlapping component on both sides, the bottom push-pull component 242 moves down and is removed. The tray falls onto the one-way overlapping component and is placed there. The trays are stacked one by one in this manner.

[0039] Preferably, the receiving plate 241 and the support frame 233 are connected, and the receiving plate 241 adjusts synchronously when the support frame 233 is adjusted. The receiving plate 241 and the support frame 233 can be connected by direct welding or through other metal connectors. The synchronously moving receiving plate 241 and support frame 233 allow for flexible material feeding while adjusting the spacing between the corresponding receiving plates 241 according to the material tray, eliminating the need for separate dimensional adjustments and simultaneously calibrating the spacing between the receiving plates 241 of the material tray to be received. This facilitates timely adjustments to subsequent material tray receiving actions, reduces the number of mechanisms and calibration steps required for calibration, offers high flexibility and convenience, eliminates the need for complex electrical automation programs, and has low error. The driving method is a linear drive module. When the linear drive module moves the support frame 233 to adapt to the current tray width, the spacing between the receiving plates 241 of the receiving section moves synchronously, simplifying the calibration method and improving calibration efficiency. The bottom frame of the storage board can also slide to connect with the slide rail, and the synchronous movement of the spacing reduces the need for correction steps, achieves adaptive adjustment, and has high work efficiency.

[0040] Preferably, the pickup module 3 is arranged on the top of the workbench 1 and connected in sequence as follows: The X-direction moving module 31, Y-direction moving module 32, and Z-direction moving module 33 each include a relatively slidable fixed rail 34 and a sliding member 35. The fixed rail 34 serves as a base with a track at its top. The sliding member 35 is slidably connected to the track of the fixed rail 34. The fixed rail 34 also includes a lead screw and a corresponding motor that drives the lead screw to rotate. The motor drives the lead screw to rotate, and the lead screw moves the sliding member 35 via a threaded connection. The sliding member 35 of the X-direction moving module 31 is fixedly connected to the fixed rail 34 of the Y-direction moving module 32. The moving end of the Y-direction moving module 32 is fixedly connected to the fixed rail 34 of the Z-direction moving module 33. The moving end of the Z-direction moving module 33 is connected to a Z-direction rotating module, which includes a rotating shaft and a pickup member 36 connected to the end of the rotating shaft. The fixed rail 34 is a slide rail, and the sliding component is a slider that cooperates with the slide rail and can slide relative to the sliding component. It will not be described in detail here.

[0041] The pickup component 36 includes a mounting bracket 37 connected to the end of the rotating shaft. The mounting bracket 37 is, for example, a frame structure, serving as the connection part to the end of the rotating shaft. A connecting groove 371 is provided on the mounting bracket 371, and a guide post 372 is connected within the connecting groove 371. A pickup frame 373 is slidably connected to the outer periphery of the guide post 372. The pickup frame 373 moves along the axial direction of the guide post 372. There are two pickup frames 373, which are opposite to each other and arranged. The guide post 372 guides the movement range of the pickup frame 373. The top of the pickup frame 373 has a protruding slider portion, which is slidably connected to the guide post 372 and restricted by the sidewalls between the connecting grooves 371, allowing it to slide synchronously and stably along a straight line. The mounting bracket 37 has two connecting slots 371, with guide posts 372 and pickup racks 373 respectively connected to them. The synchronously moving pickup rack 373 moves down to a preset position entered in the system and clamps the material, which is offset from the preset position. Under clamping, the rectangular strip of material is clamped along its length, thus centering it. Automatic length position correction is integrated during transfer, ensuring the material is clamped from the offset preset position to the accurate position along its length. This integrates multiple functions of pickup, transfer, and position correction, simultaneously clamping the material and calibrating its length position during pickup. It eliminates the need for multiple distributed structures, saving resources and simplifying the pickup and position correction steps, resulting in high efficiency.

[0042] Preferably, the pickup rack 373 is provided with a drive groove 3731, and a pneumatic drive component 3732 is connected to the pickup rack 373. The moving end of the pneumatic drive component 3732 is inserted into the drive groove 3731. The pickup rack 373 is detachably connected to the mounting bracket 37. During operation, it is detachably installed on the mounting bracket 37, and different pickup racks 373 can be replaced according to different material lengths to improve the application range of the pickup rack 373.

[0043] Preferably, the precision positioning module 4 includes a pushing module 41 and a positioning platform 42. The pushing module 41 is connected to the side wall of the positioning platform 42. The top of the positioning platform 42 is divided into a connecting station for connecting the pushing module 41 and a positioning station for determining the width of the material. Two sets of positioning surfaces are provided at each positioning station. Each positioning surface includes at least two mutually perpendicular planes for abutting the vertically inserted material from two horizontal directions. The positioning surface can be formed by two mutually perpendicular plates, and the position of the perpendicular planes is not specifically limited. The positioning surfaces can abut against two adjacent sides of the material.

[0044] The pushing module 41 includes a pushing block 411, which is movable in the horizontal direction. The bottom of the pushing block 411 has a second driving groove 412 for the moving end of the pushing module 41 to insert into, and a driving surface 413 for driving the material to move in the width direction. The positioning surface opposite the driving surface 413 is a fixed-width surface 414. The bottom of the pushing block 411 is slidably connected to the top of the positioning platform 42 via a slide rail. The pushing module 41 is an electric telescopic rod or a pneumatic telescopic rod. The moving end of the pushing module 41 is inserted into the second driving groove 412, causing the driving surface 413 to move linearly, driving the material to move in the width direction, and finally engaging with one of the vertical surfaces of the positioning surface to complete the positioning.

[0045] Preferably, the flexible transfer component 5 includes a flexible clamp 51 and a flexible moving disk 52. The moving disk can drive the clamp to clamp the material positioned by the precision positioning module 4 and vertically remove it to a preset assembly station. The flexible clamp 51 of the flexible transfer component 5 clamps the material from the thickness direction and lifts it vertically to a certain height. Driven by a three-axis or two-axis linear module 2331, it can be transported to multiple preset positions to await accurate insertion of terminals or pins. The flexible moving disk 52 also includes, for example, a linear module 2331 that can move in both vertical and horizontal directions, and the flexible clamp 51 can be pneumatically clamped and fixed from the vertical direction of the material.

[0046] Furthermore, after the flexible chuck 51 of the flexible transfer component 5 moves from the worktable 1, a visual recognition module can be set along the movement path. The visual recognition module takes a picture of the material's posture as it passes by, thereby determining whether the material's current state conforms to the correct orientation. If not, the flexible chuck 51 clamps the material and rotates 180 degrees under the drive of the rotating shaft, finally transferring it to a preset position to wait for the pin. The rotating structure can be similar to or the same as the structure of the picking module 3 described above, and is not limited here.

[0047] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the invention without departing from the principles and spirit of the invention, and all such changes should fall within the protection scope of the claims of the present invention.
