Description

Technical Field

[0001] This application relates to the field of automated feeding equipment technology, and more particularly to an automated sorting and feeding equipment. Background Technology

[0002] On automated electronic assembly lines, automatic feeding equipment is responsible for picking up and transferring small electronic components through vacuum nozzles.

[0003] The existing equipment operates by directly transferring the part to the next station after adsorption at the pick-up station. This process lacks a step for real-time online detection and assessment of the adsorption status before transfer. The equipment cannot identify insufficient or failed adsorption due to component warping, surface contamination, or positioning deviation.

[0004] Components that fail to adhere properly are prone to falling off during transport, causing frequent downtime and affecting production efficiency. More seriously, poorly adhered components may be carried into subsequent mounting or soldering stations, causing batch quality defects that are difficult to trace and resulting in significant losses. Summary of the Invention

[0006] To achieve the above objectives, this application provides the following technical solution: An automatic sorting and feeding device includes a frame, a turntable, a rotary drive, at least one fixture, a feeding assembly, a waste collection device, and a vacuum control system.

[0007] Furthermore, the rotary drive is configured as follows: When the vacuum pressure value detected by the vacuum detection device is greater than or equal to the preset value, the turntable is driven to rotate the fixture along the first direction to the feeding assembly; When the vacuum pressure value detected by the vacuum detection device is less than the preset value, the turntable is driven to rotate the fixture in a second direction opposite to the first direction to the waste collection device.

[0008] Furthermore, the vacuum line includes a gas slip ring; The stationary part of the air slip ring is connected to the vacuum generating device and the vacuum detection device; The rotating part of the air slip ring is provided with multiple interfaces, and the number of interfaces corresponds to the number of the fixtures; Each of the interfaces is connected to a vacuum channel within a corresponding fixture.

The push rod is vertically and flexibly disposed at the bottom of the placement slot, and the push rod is provided with a plurality of pushing parts arranged at intervals along its length direction; The output end of the vertical drive component is connected to the push rod and is used to drive the push rod to move vertically up and down, so that the pushing part extends into or out of the placement slot. The output end of the horizontal drive component is connected to the push rod or the vertical drive component, and is used to drive the push rod to perform horizontal reciprocating motion along the length direction of the placement slot.

[0011] Furthermore, a limiting part is provided at the end of the placement slot away from the turntable to limit the horizontal movement of the product.

[0012] Furthermore, the receiving seat includes a first side plate and a second side plate that are parallel and spaced apart, and the placement groove is formed between the first side plate and the second side plate; The bottom of the first side plate extends toward the second side plate to form a first support flange; The bottom of the second side plate extends toward the first side plate to form a second support flange; The first support flange and the second support flange are opposite to each other and spaced apart, and together they form a support plane for supporting the product. The gap between the first support flange and the second support flange forms a channel through which the pushing part on the push rod passes.

[0013] Furthermore, the vertical drive component includes a cam plate, a connecting shaft, a connector, and a vertical driver. The cam plate is fixedly installed and has an annular cam groove on it; One end of the connecting shaft is fixedly connected to the push rod through the connecting piece, and the other end is provided with a sliding part that slides in cooperation with the annular cam groove; The output end of the vertical driver is connected to the connecting shaft for driving the connecting shaft to rotate around its axis, so that the sliding part moves along the annular cam groove, thereby driving the push rod and the pushing part to make vertical lifting and lowering movements through the connecting member.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0033] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0034] Figures 1 to 9 An automatic sorting and feeding device provided in this application includes a frame 1, a turntable 2, a rotary drive 3, at least one fixture 4, a feeding assembly 5, a waste collection device, and a vacuum control system.

[0035] The rotary drive component 3 (such as a servo motor or stepper motor) is mounted on the frame 1, and its output end is connected to the turntable 2 through a transmission component such as a coupling or reducer to drive the turntable 2 to rotate around its central axis.

[0036] The fixture 4 is mounted on the turntable 2 and has vacuum adsorption holes 41 for adsorbing products. The turntable 2 is preferably a disc-shaped structure with multiple mounting stations equidistantly arranged along its outer circumference. Each mounting station has a fixture 4 that can be detachably mounted on it.

[0037] The vacuum control system includes a vacuum generating device (not shown in the figure, such as a vacuum generator or vacuum pump) and a vacuum detection device (not shown in the figure, such as a vacuum pressure sensor or vacuum switch). The vacuum adsorption port 41 is connected to the vacuum generating device and the vacuum detection device located on the frame 1 through a vacuum pipeline consisting of a vacuum flow channel set inside the fixture 4 and components such as a rotary joint (such as a slip ring). Thus, regardless of how the turntable 2 rotates, a stable vacuum adsorption force can be provided to the fixture 4 in the working position, and the vacuum pressure status of the adsorption point can be monitored in real time.

[0038] Both the feeding assembly 5 and the waste collection device are located on the rotation path of the turntable 2. The feeding assembly 5 is used to receive and transport products that are deemed qualified to the next process (such as the mounting station), and its specific structure will be described in detail later. The waste collection device is used to collect products that are deemed unqualified. Specifically, in this embodiment, the waste collection device is a waste box 6, which is located below the rotation path of the turntable 2, with its opening facing the turntable 2, and is used to receive products 100 that fall off the fixture 4. Specifically, since the waste box 6 has its opening facing the turntable and is located below it, the fallen products 100 will fall directly into the waste box 6 under the action of gravity, completing the collection of waste.

[0039] The rotary drive 3 is connected to the vacuum detection device via a control system (e.g., PLC) and is configured to selectively drive the turntable 2 to rotate towards the feeding assembly 5 or the waste collection device based on the vacuum pressure value detected by the vacuum detection device. In a preferred embodiment, the rotary drive 3 is configured to: when the vacuum pressure value detected by the vacuum detection device is greater than or equal to a preset value, drive the turntable 2 to rotate the fixture 4 towards the feeding assembly 5 in a first direction; when the vacuum pressure value detected by the vacuum detection device is less than the preset value, drive the turntable 2 to rotate the fixture 4 towards the waste collection device in a second direction opposite to the first direction.

[0040] During operation, the rotary drive 3 actuates, driving the turntable 2 to rotate the fixture 4 to the loading position. Then, upstream equipment (such as a robotic arm) places the PCB terminals to be processed onto the fixture 4 at the loading position. The vacuum control system then activates, and the vacuum generator operates, adsorbing the product through the vacuum adsorption hole 41. Simultaneously, the vacuum detection device begins real-time monitoring of the vacuum pressure value at the adsorption point. This vacuum pressure value directly reflects the adhesion and sealing condition between the product and the adsorption surface of the fixture 4: if the product is placed flat, without warping, and with a clean surface, the vacuum level will quickly establish and stabilize at a high level (i.e., reaching or exceeding the preset qualified threshold); conversely, if the product has defects, is improperly placed, or the fixture has poor sealing, the vacuum level will not reach the threshold.

[0041] The control system continuously compares the detected values ​​with the preset acceptable thresholds and issues sorting instructions to the rotary drive component 3 accordingly. When the detected vacuum pressure value reaches or exceeds the preset qualified value, the control system determines that the product adsorption is good and the condition is qualified. Subsequently, the rotary drive 3 drives the turntable 2 to rotate by a predetermined angle in the first direction (e.g., clockwise), positioning the fixture 4 carrying the qualified product to the unloading station corresponding to the feeding assembly 5. After reaching the station, the control system controls the vacuum generator to shut off or introduces positive pressure air into the vacuum pipeline to cancel the adsorption force. The product automatically falls into the receiving port of the feeding assembly 5 under the action of gravity, completing the loading of qualified products.

[0042] When the detected vacuum pressure value is lower than the preset acceptable value, the control system determines that the product has poor adsorption and is unqualified. Subsequently, the rotary drive 3 drives the turntable 2 to rotate in a second direction opposite to the first direction (e.g., counterclockwise), positioning the fixture 4 carrying the unqualified product at the waste station corresponding to the waste collection device. Similarly, at this station, the adsorption force is released, and the product (usually due to weak adsorption) falls directly into the waste collection device under its own weight, achieving automatic rejection.

[0043] In a preferred embodiment, to achieve stable vacuum supply and detection in a rotating state, the vacuum pipeline includes a slip ring 7. The stationary part 71 of the slip ring 7 is connected to the vacuum generating device and the vacuum detection device. The rotating part 72 of the slip ring 7 is provided with multiple interfaces, the number of which corresponds to the number of fixtures. Each interface is connected to a vacuum channel in a corresponding fixture 4.

[0044] like Figure 3 As shown, the stationary part 71 (stator) of the air slip ring 7 is mounted on the frame 1 by a fixed bracket. The stationary part 71 is provided with an air inlet / detection interface, which is directly connected to the outlet of a vacuum generating device (such as a vacuum generator) and the inlet of a vacuum detection device (such as a vacuum pressure sensor) located on the frame 1 through a rigid or flexible vacuum tube, thereby connecting to a fixed vacuum source and detection circuit.

[0045] The rotating portion 72 (rotor) of the slip ring 7 rotates synchronously with the rotating shaft of the turntable 2 (or directly with the turntable 2). In this embodiment, the outer periphery of the rotating portion 72 is provided with multiple independent vacuum channel interfaces along the circumferential direction. The number of these interfaces corresponds one-to-one with the number of fixtures 4 provided on the turntable 2. For example, if four fixtures 4 are evenly distributed on the turntable, then the rotating portion 72 of the slip ring 7 is provided with four vacuum channel interfaces accordingly.

[0046] Each vacuum channel interface is connected to the vacuum channel inlet inside a corresponding fixture 4 via an independent connecting pipe 73 (such as a flexible vacuum silicone tube or a built-in metal flow channel). This forms an independent, closed, and continuous vacuum transfer path from the fixed vacuum source / detection end to each rotating fixture.

[0047] When the turntable 2 rotates, regardless of the angle of the fixture 4, its vacuum adsorption and detection circuits remain unobstructed through the air slip ring 7 and are not affected by the rotational motion.

[0048] Please refer to Figures 1 to 7The feeding assembly 5, as an automated transfer mechanism for qualified products, functions to horizontally push products falling from the turntable 2 to the downstream picking station. This assembly includes a receiving seat 51, a push rod 52, a vertical drive component 53, and a horizontal drive component 54. The receiving seat 51 is fixed to the frame 1 by bolts or other fasteners and is located below the rotation trajectory of the turntable 2. Its upper surface has a placement groove 511 extending horizontally (i.e., pointing towards the downstream picking station). The cross-section of this placement groove 511 is typically U-shaped or V-shaped (preferably U-shaped in this embodiment), and its size is slightly larger than the product. It serves to receive qualified products falling from the fixture 4 and guide them along a straight line.

[0049] The push rod 52 is a long rod-shaped moving component that is vertically mounted at the bottom of the placement slot 511. The push rod 52 has multiple pushing parts 521 arranged at intervals along its length. These pushing parts 521 can be in the form of protrusions, pins, or baffles.

[0050] The output end of the vertical drive component 53 (e.g., a cylinder, electric push rod, or cam lifting mechanism) is connected to the push rod 52 to drive the push rod 52 to move vertically up and down, so that the pushing part 521 extends into or out of the placement slot 511. When a product needs to be pushed, the push rod 52 is driven to rise, so that the pushing part 521 extends from the bottom of the placement slot 511 to a certain height, just enough to contact and push the product in the slot; when the pushing is completed or the product is reset, the push rod 52 is driven to fall, so that the pushing part 521 retracts below the bottom of the placement slot 511, thereby making room for subsequent products to fall and avoiding interference.

[0051] The output end of the horizontal drive unit 54 (e.g., a servo motor with a lead screw module or a linear cylinder) is connected to the push rod 52 itself or to the sliding platform that carries the vertical drive unit 53 and the push rod 52, for driving the push rod 52 (and its pushing part 521) to perform horizontal reciprocating motion along the length direction of the placement groove 511.

[0052] The workflow of the feeding assembly 5 is as follows: Qualified products fall from the fixture 4 of the turntable 2 into the placement groove 511 of the receiving seat 51. At this time, the push rod 52 is in the lowered reset state, and the pushing part 521 retracts. Then, the vertical drive 53 is activated, driving the push rod 52 to rise, causing the pushing part 521 to extend into the placement groove 511. The horizontal drive 54 is then activated, driving the push rod 52 and the pushing part 521 to move horizontally along the placement groove 511 towards the picking station, thereby smoothly pushing one or more products forward one or more station distances.

[0053] After one push is completed, the vertical drive component 53 drives the push rod 52 to descend and reset, and then the horizontal drive component 54 drives the push rod 52 to return to its original horizontal position. At this point, the feeding assembly 5 completes one work cycle and waits to receive the next product and repeat the above actions. Through this composite motion of "lifting-pushing-resetting," intermittent, highly reliable automatic feeding of products is achieved.

[0054] It should be noted that a limiting part 512 is provided at the end of the placement slot 511 away from the turntable 2, which is used to limit the horizontal movement of the product. Please refer to... Figure 5 and Figure 7 The limiting part 512 is preferably a rigid stop block, integrally formed with the receiving seat 51 and located at the end of the receiving seat 51. This ensures that when the product is pushed to this end by the pushing part 521 on the push rod 52, it can be reliably blocked by the limiting part 512 and stop at a preset, accurate target position. This target position is usually precisely aligned with the receiving port of the downstream robot, detection sensor, or another section of the conveyor line, effectively preventing the product from rushing out of the placement slot 511 under inertia, causing damage or interference to surrounding equipment.

[0055] Please refer to Figure 4 , Figure 5 and Figure 7 ( Figure 4 The first side plate 513 is far from the second side plate 514. Figure 5 In a preferred embodiment, the receiving seat 51 includes a first side plate 513 and a second side plate 514 that are parallel and spaced apart, with a placement groove 511 formed between the first side plate 513 and the second side plate 514.

[0056] The bottom of the first side plate 513 extends toward the second side plate 514 to form a first support flange 5131. The bottom of the second side plate 514 extends toward the first side plate 513 to form a second support flange 5141.

[0057] The first support flange 5131 and the second support flange 5141 are positioned opposite each other and spaced apart, together forming a support plane for supporting the product. When the product falls from the turntable 2 into the placement groove 511, its two ends or bottom edges rest smoothly on the support plane formed by the first support flange 5131 and the second support flange 5141, avoiding direct contact or friction between the product and other parts of the groove bottom, thus ensuring the stability of the product's posture.

[0058] The gap between the first support flange 5131 and the second support flange 5141 forms a channel through which the pushing part 521 on the push rod 52 passes. When it is necessary to push the product, the vertical drive member 53 drives the push rod 52 to rise. The pushing part 521 on the push rod 52 rises accordingly and passes through the channel between the first support flange 5131 and the second support flange 5141 until its top is above the support plane, thereby being able to contact and push the rear end of the product.

[0059] Driven by the horizontal drive member 54, the pusher 521 moves horizontally. Since the pusher 521 moves in the channel and does not interfere with the support flange, a smooth thrust can be applied without disturbing the product on the support plane.

[0060] Please refer to Figure 8 and Figure 9 The vertical drive unit 53 includes a cam plate 531, a connecting shaft 532, a connector 533, and a vertical driver 534.

[0061] A cam plate 531 is fixedly installed, and an annular cam groove 5311 is provided on it. The outline of the groove consists of at least one rising section, one horizontal (or approximately horizontal) holding section, one descending section and one reset section.

[0062] One end of the connecting shaft 532 is fixedly connected to the push rod 52 via the connector 533, and the other end is provided with a sliding part 5321 that slides in cooperation with the annular cam groove 5311.

[0063] The output end of the vertical driver 534 is connected to the connecting shaft 532 for driving the connecting shaft 532 to rotate around its axis, so that the sliding part 5321 moves along the annular cam groove 5311, thereby driving the push rod 52 and the pushing part 521 to make vertical lifting and lowering movements through the connecting member 533.

[0064] Specifically, when the sliding part 5321 moves to the rising section of the annular cam groove 5311, the axis of the connecting shaft 532 is pushed away from the initial position. This displacement is transmitted through the rigid connecting member 533 and is converted into an upward pulling force on the push rod 52, driving the push rod 52 and the pushing part 521 to rise against gravity until the pushing part 521 extends out of the support plane of the placement groove 511.

[0065] When the sliding part 5321 enters the top holding section, the axis of the connecting shaft 532 hovers at a relatively stable high position, so that the push rod 52 can remain at a high position for a period of time. At this time, the horizontal drive member 54 can drive the push rod to perform horizontal pushing operations.

[0066] When the sliding part 5321 enters the descending section, the axis of the connecting shaft 532 returns to the initial position under the guidance of the annular cam groove 5311, so that the push rod 52 descends and resets smoothly under the assistance of gravity or spring, and the pushing part 521 retracts into the channel.

[0067] The sliding part 5321 returns to the starting point after passing through the reset section, completing one motion cycle and preparing for the next lifting and lowering.

[0068] Specifically, the vertical drive member 53 also includes a first slide rail 535, which is fixedly installed and extends parallel to the horizontal section of the annular cam groove 5311. The connecting member 533 is slidably connected to the first slide rail 535. When the connecting shaft 532 rotates to the point where its sliding part 5321 corresponds to the horizontal section of the annular cam groove 5311, the connecting member 533 slides horizontally under the constraint of the first slide rail 535.

[0069] Please refer to Figure 4 In a preferred embodiment, the horizontal drive member 54 includes a horizontal driver 541, a fixedly disposed second slide rail 542, a slider 543 that slides with the second slide rail 542, and a mounting plate 544 that is fixedly connected to the slider 543.

[0070] The vertical drive unit 53 is mounted on the mounting plate 544. The output end of the horizontal drive unit 541 is connected to the mounting plate 544 for driving the mounting plate 544 to drive the vertical drive unit 53 and the push rod 52 to perform horizontal reciprocating motion along the extension direction of the second slide rail 542.

[0071] Specifically, when the horizontal actuator 541 operates, the rotational drive it generates is converted into a linear traction force on the mounting plate 544 through a transmission mechanism. This traction force drives the mounting plate 544, causing all the sliders 543 on it to slide along the second slide rail 542. Since the vertical drive member 53 and the push rod 52 are fixed to the mounting plate 544 as a whole, they are driven by the mounting plate 544 as a rigid motion unit, thereby realizing horizontal reciprocating linear motion along the extension direction of the second slide rail 542 (i.e., the direction of the placement slot 511).
