Description

Technical Field

[0001] This invention belongs to the field of vibratory feeding technology, and particularly relates to a vibratory feeder assembly. Background Technology

[0002] In automated assembly lines for connectors, precision connectors, and automotive electronic components, slender shaft-type precision parts such as PIN pins are core basic connectors. These parts have a differentiated shape structure with a thin needle tip at one end and a thick needle tail at the other. The dimensional accuracy and surface plating integrity directly determine subsequent assembly, conductivity, and finished product yield. Currently, in automated production processes, the industry generally uses vibratory feeders as standard feeding equipment. Vibration drives the randomly stacked PIN pins to be arranged in layers and in an orderly manner. Then, a matching linear conveyor channel continuously transports individual workpieces to the back-end inspection, insertion, and riveting precision machining stations.

[0003] According to Chinese Patent Publication No. CN223813055U, an automatic feeding device for inserting pins with vibration is disclosed, including a vibratory feeder mechanism and a reversing discharge mechanism. The vibratory feeder mechanism has an upward-opening conveyor channel on the discharge side, and the conveyor channel is inclined downward. The reversing discharge mechanism includes a discharge rack, a discharge pipe, and a discharge platform. The discharge pipe is inclined relative to the conveyor channel, and the included angle between the two is an acute angle. The higher end of the discharge pipe has an upward-opening slot, and the lower end of the conveyor channel is located above the slot. The top of the discharge platform has a discharge channel, and the lower end of the discharge pipe corresponds to the discharge channel.

[0004] However, the above solution has the following drawbacks because it relies solely on a rigid discharge pipe and discharge chute with a fixed angle to guide the workpiece's posture: the tilt angle and installation height of the discharge pipe and conveyor are fixed and non-adjustable, which can only accommodate pin products of a single shape and size; when the production line switches to PIN pins with different tail thicknesses and diameters, the entire discharge pipe system needs to be disassembled and replaced, resulting in a long line changeover and debugging cycle, which cannot meet the needs of flexible production of multiple specifications. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the tilt angle and installation height of the discharge pipe and conveyor are fixed and cannot be adjusted, which can only adapt to pin products with a single shape and size; when the production line switches to PIN pins with different tail thicknesses and different diameter specifications, it is necessary to disassemble and replace the entire discharge pipe components, resulting in a long line change and debugging cycle, which cannot meet the needs of flexible production of multiple specifications. Therefore, a vibratory feeder assembly is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A vibratory feeder feeding assembly includes two worktables and two fixed seats. A vibratory feeder is fixedly connected to the top surface of each worktable. A linear feeding unit is provided between the vibratory feeder and the fixed seats. The linear feeding unit has a feeding channel inside. A baffle is provided above the feeding channel. One side of both the feeding channel and the baffle is connected to a mounting groove. An auxiliary feeding assembly is provided inside the mounting groove. The auxiliary feeding assembly includes: The connecting seat is located inside the mounting slot, and the bottom surface of the connecting seat is fixedly connected to the top surface of the baffle. The limiting slider is slidably connected inside the connecting seat, and an adjustment unit is provided on the top of the limiting slider. A cavity is opened on the bottom side of the inner side of the limiting slider, and a fixed seat is provided inside the cavity. An inclined seat is fixedly connected to the fixed seat on the side away from the cavity. A hollow shaft is rotatably connected inside a limiting slider, and limiting through holes are provided at both ends of the hollow shaft. The fixed seat is fixedly connected to the outside of the hollow shaft. Two torsion springs are symmetrically sleeved on the outside of the hollow shaft, and the torsion springs are equipped with compression adjustment units.

[0007] As a further description of the above technical solution: The adjustment unit includes: The screw is rotatably connected to the top of the limiting slider via a bearing, and the screw is threaded inside the connecting seat. The top end of the screw extends to the outside of the connecting seat and is fixedly connected to the first rotating handle.

[0008] As a further description of the above technical solution: The compression adjustment unit includes Both limiting sleeves are located inside the limiting slider, and the limiting sleeves are fitted outside the hollow shaft.

[0009] As a further description of the above technical solution: The compression adjustment unit further includes: The rotating sleeves are rotatably sealed outside the hollow shaft. Each of the two rotating sleeves is fixedly connected to a connecting block on one side that is close to each other. One side of the connecting block is fixedly connected to one end of the torsion spring.

[0010] As a further description of the above technical solution: The compression adjustment unit further includes: Two circular plates are symmetrically rotated and connected inside the hollow shaft. Connecting frames are fixedly connected to both sides of the outer surface of the circular plates. The side of the connecting frame away from the circular plate is fixedly connected to the inner wall of the rotating sleeve. The connecting frame is slidably connected inside the limiting through hole.

[0011] As a further description of the above technical solution: The compression adjustment unit further includes: A connecting shaft is rotatably connected inside the hollow shaft and is fixedly connected inside the circular plate. One end of the connecting shaft extends to the outside of the hollow shaft and is fixedly connected to a second rotating handle.

[0012] As a further description of the above technical solution: Also includes: Two limiting grooves are located on the bottom side inside the two linear feeding units, and the top of the limiting grooves is connected to the feeding channel through the chip removal through hole; The collection box is located inside the limiting groove.

[0013] As a further description of the above technical solution: Also includes: The fixed base is provided with a multi-station rotary table on the side away from the vibratory plate, and multiple rotating electric gripper units are distributed in a circumferential array on the multi-station rotary table.

[0014] Compared with existing technologies, a vibratory feeder assembly employing the above-mentioned technical solution has the following beneficial effects: 1. In this invention, a two-stage independent adjustment structure is adopted to achieve flexible adaptation of multiple specifications of PIN needles. The operator can rotate the second handle to steplessly and synchronously adjust the preload torque of the double torsion spring in conjunction with the compression adjustment unit. When processing coarse needle products, the spring downward pressure torque is increased to ensure stable reversal of the reverse PIN needle; when processing fine needle products, the spring preload is reduced to amplify the floating buffer space of the inclined seat and disperse the concentrated pressure at the needle tip fulcrum. At the same time, the overall vertical height of the inclined seat can be precisely finely adjusted by the first handle in conjunction with the screw lifting mechanism to match the height difference between the needle tip and the needle tail of various PIN needles. It can be compatible with workpieces of various sizes without changing the reversing parts, effectively reducing the time for production line changeover and debugging and improving the versatility of the equipment.

[0015] 2. In this invention, the inclined seat is combined with symmetrical double torsion springs to form an elastic floating structure. During the reverse PIN needle flipping process, the inclined surface can float slightly to buffer the instantaneous impact, disperse the concentrated pressure at the needle tip fulcrum, and prevent the needle tip from being crushed and damaged. The inclined surface is fully covered with polyurethane soft pads, and the workpiece only contacts the soft pads, avoiding scratches on the plating caused by hard metal friction. The workpiece completes the reversal in place within the closed feeding channel, without lateral unloading and uninterrupted conveying, ensuring the stability and continuity of feeding.

[0016] 3. In this invention, the limiting groove, chip discharge through hole, and pull-out collection box are linked to form a chip discharge structure. During the conveying process, metal dust, burrs, and chips generated by the workpiece can automatically fall into the collection box through the chip discharge through hole for centralized collection. The limiting groove can constrain the position of the collection box to prevent vibration, displacement, and material leakage. During cleaning, only the box body needs to be pulled out, without disassembling the linear feeding unit and reversing component. This can continuously remove debris in the channel, prevent chip accumulation from causing scratches on the workpiece plating, and prevent the inclined seat from blocking and stopping the machine. This reduces the frequency of daily equipment maintenance and improves the continuous operation stability and uptime of the equipment. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-11 This invention provides a technical solution: a vibratory feeder assembly, comprising two worktables 1 and two fixed seats 5. A vibratory feeder 4 is bolted to the top surface of each worktable 1. The vibratory feeder 4 is used for automatic layering and sorting of scattered PIN needles. A linear feeding unit 6 is provided between the vibratory feeder 4 and the fixed seats 5. The linear feeding unit 6 drives the PIN needles forward smoothly by high-frequency linear vibration. An elongated feeding channel 9 is provided inside the linear feeding unit 6. A baffle 8 is detachably mounted above the feeding channel 9 to close the upper part of the feeding channel 9 and prevent the workpiece from bouncing out. One side of both the feeding channel 9 and the baffle 8 is connected to a mounting groove 13. The mounting groove 13 is a regular rectangular groove. An auxiliary feeding assembly 7 is provided inside the mounting groove 13. The auxiliary feeding assembly 7 includes: The connecting seat 701 is located inside the mounting groove 13, and the bottom surface of the connecting seat 701 is fixedly connected to the top surface of the baffle 8 by countersunk bolts. The cross-sectional shape of the connecting seat 701 is set as a rectangular structure. The limiting slider 704 has a rectangular cross-sectional shape and is slidably connected inside the connecting seat 701. An adjustment unit is provided on the top of the limiting slider 704. A cavity is opened on the bottom side of the inner side of the limiting slider 704. A fixed seat 706 is provided inside the cavity. An inclined seat 707 is fixedly connected to the side of the fixed seat 706 away from the cavity. The inclined seat 707 has an axial slope that is higher at the front and lower at the back along the feeding direction of the PIN needle. The inclined surface faces the feeding side of the vibrating plate 4. A 2mm polyurethane soft pad is pasted on the surface of the inclined surface of the inclined seat 707 to avoid scratches from hard friction of the PIN needle. The height of the top of the inclined surface matches the height of the needle tail, and the height of the bottom of the inclined surface matches the height of the needle tip, so as to realize the avoidance of the PIN needle in the forward direction and the extrusion and flipping of the workpiece in the reverse direction. The hollow shaft 705 is rotatably connected inside the limiting slider 704, and both ends of the hollow shaft 705 are provided with limiting through holes 709. The fixed seat 706 is fixedly connected to the outside of the hollow shaft 705. When the hollow shaft 705 rotates, it can synchronously drive the fixed seat 706 and the inclined seat 707 to swing synchronously in a small amplitude. Two torsion springs 708 are symmetrically sleeved on the outside of the hollow shaft 705, and the torsion springs 708 are equipped with compression adjustment units; The adjustment unit includes: The screw 702 is rotatably connected to the top of the limiting slider 704 via a bearing, and the screw 702 is threadedly connected to the inside of the connecting seat 701. The top end of the screw 702 extends to the outside of the connecting seat 701 and is fixedly connected to the first rotating handle 703. Rotating the first rotating handle 703 drives the screw 702 to rotate synchronously. The threaded transmission drives the limiting slider 704 to slide up and down along the inner cavity of the connecting seat 701, synchronously driving the hollow shaft 705 and the inclined seat 707 to rise and fall as a whole. Height locking is achieved by thread self-locking, without the need for additional locking parts, and is suitable for direct vibration conditions. The compression regulation unit includes: Both limiting sleeves 710 are set inside the limiting slider 704, and the limiting sleeves 710 are sleeved outside the hollow shaft 705 to axially limit the torsion spring 708 and prevent the torsion spring 708 from moving left and right. Rotary sleeve 711, rotating seal outside hollow shaft 705, two rotating sleeves 711 are fixedly connected to each other on the side close to each other, and one side of the connecting block 712 is fixedly connected to one end of torsion spring 708. Two circular plates 713 are symmetrically rotated and connected inside the hollow shaft 705. Connecting brackets 714 are fixedly connected to both sides of the outer side of the circular plates 713. The side of the connecting bracket 714 away from the circular plates 713 is fixedly connected to the inner wall of the rotating sleeve 711. The connecting bracket 714 is slidably connected inside the limiting through hole 709. The connecting shaft 715 is rotatably connected inside the hollow shaft 705 and is fixedly connected inside the circular plate 713. One end of the connecting shaft 715 extends to the outside of the hollow shaft 705 and is fixedly connected to a second rotating handle 716. A limiting unit is sleeved on the outside of the connecting shaft 715. The limiting unit adopts a miniature power-off electromagnetic self-locking brake of model MHBS05AA. After the torque adjustment is completed, the brake is de-energized and locks the connecting shaft 715 to counteract the rotational torque caused by the direct vibration and prevent the preload of the torsion spring 708 from decaying with vibration. Also includes: A multi-station rotary table 2 is provided on the side of the fixed base 5 away from the vibratory plate 4. Multiple rotating electric gripper units 3 are arranged in a circular array on the multi-station rotary table 2 to clamp workpieces with the same orientation to complete precision machining.

[0021] The specific usage method is as follows: According to the diameter of the PIN needle to be processed by vibration feeding, manually rotate the second handle 716 to drive the connecting shaft 715 to rotate. Utilizing the linkage effect between the connecting shaft 715 and the two circular plates 713, the power is transmitted to the two circular plates 713. The two circular plates 713 will drive the rotating sleeve 711 and the connecting block 712 to rotate through the connecting frame 714, compressing or releasing the torsion spring 708 and changing the preload of the torsion spring 708. When processing large-diameter, thick-tail PIN needles, continuously rotate the second handle 716 clockwise to increase the preload torque of the torsion spring 708, increase the vertical downward pressure component of the inclined seat 707 on the PIN needle tail, and ensure that reverse PIN needles with larger height differences can be processed. Sufficient turning torque is obtained to stably complete the 180° in-situ posture transformation; if machining fine-diameter, thin-walled, easily damaged PIN needles, the second handle 716 is rotated counterclockwise to reduce the spring preload torque, release the upward floating margin of the inclined seat 707, increase the buffer floating stroke when the PIN needle pushes against the inclined surface, and disperse the concentrated pressure at the needle tip fulcrum during the turning process, avoiding defects such as needle tip collapse, surface plating scratches, and workpiece deformation; after the torque value is adjusted to the correct position, the miniature power-off electromagnetic self-locking brake of model MHBS05AA is activated to lock the connecting shaft 715, offsetting the risk of rotational loosening caused by the long-term high-frequency vibration of the linear feeding unit 6, and maintaining the preload of the set torsion spring 708 stably throughout the process without repeated secondary adjustments; After completing the torque adjustment, adjust the overall vertical position of the inclined seat 707 based on the height difference between the tip and tail of the PIN needle. Manually rotate the first handle 703 to drive the screw 702 to rotate. The rotation of the screw 702 drives the limit slider 704 to rise and fall vertically along the connecting seat 701. During the rise and fall of the limit slider 704, the internal hollow shaft 705, the fixed seat 706, and the inclined seat 707 are simultaneously moved up and down synchronously. The vertical installation height of the inclined seat 707 inside the feeding channel 9 is precisely adjusted so that the inclined surface of the inclined seat 707 matches the outer wall of the PIN needle. After the adjustment is completed, stop rotating the first handle 703. After adjustment, the PIN needles are poured into the vibratory feeder 4. The vibratory feeder 4 generates high-frequency micro-amplitude vibrations by relying on the bottom vibrator, which drives the randomly stacked PIN needles to separate into layers and automatically complete the orderly sorting. The needles are then discharged in a uniform flat posture and continuously conveyed to the long strip feeding channel 9 of the linear feeding unit 6. The PIN needles are usually shaft-like parts with one end being thin and pointed and the other end being thick and large. The vertical height of the needle tip itself is a fixed value H2, and the vertical height of the large end of the needle tail is H1. The two satisfy H1 > H2. The inclined seat 707 is arranged in an axial slope with the front higher and the back lower along the PIN needle conveying direction inside the linear feeding channel 9. The vertical height of the front section of the inclined seat 707 on the feeding side is precisely matched with the needle tail height H1, and the vertical height of the bottom section on the discharge side is exactly equal to the needle tip height H2. The inclined surface of the inclined seat 707 is fully covered with a 2mm thick polyurethane buffer soft pad. The width of the inclined surface on the left and right is consistent with the width of the cavity inside the feeding channel, and there is no lateral tilt. When the PIN needle is fed forward (tip facing forward) into the feeding channel 9, the tip of the PIN needle first reaches the area of ​​the inclined seat 707. Under the continuous high-frequency direct vibration driving force of the linear feeding unit 6, the entire needle is laid flat against the soft pad at the bottom of the feeding channel 9 and fed at a constant speed along the center line of the feeding channel 9 towards the reversing area of ​​the inclined seat 707. The part of the PIN needle that first enters the coverage area of ​​the inclined seat 707 is the slender tip. The highest point of the tip is only H2, which just matches the passage gap formed between the bottom of the inclined seat 707 and the bottom surface of the feeding channel 9. The tip is directly embedded in this gap and slides forward gently along the bottom of the slope. After the tip of the PIN needle is completely conveyed out of the inclined seat 707, the tail of the needle is conveyed into the interior of the inclined seat 707. At this time, the height of the inclined seat 707 will not affect the conveying of the PIN needle. When the PIN needle is conveyed to the feeding channel 9 in the reverse direction (needle tail facing forward), the height of the thick needle tail of the PIN needle is relatively higher than that of the needle tip. The thick needle tail of the PIN needle contacts the front slope of the inclined seat 707 first. The inclined surface with a higher front and lower rear simultaneously applies downward pressure and backward resistance force to the needle tail. The needle tip of the PIN needle continuously adheres to the bottom surface of the channel to form a fixed rotation fulcrum. When the linear feeding unit 6 continuously pushes the PIN needle forward, the inclined seat 707 presses down on the needle tail under the action of the torsion spring 708. The workpiece rotates 180° in place in the closed channel with the needle tip as the fulcrum. During the rotation, the PIN needle pushes the inclined seat 707 and can float slightly upward to buffer the instantaneous impact and reduce the concentrated force on the needle tip. After the rotation is completed, the PIN needle switches to a needle tip facing forward posture and is smoothly conveyed out along the low gap of the inclined surface without leaving the feeding channel 9 throughout the entire process, and the conveying is uninterrupted. The multi-station rotary table 2 drives the rotary electric gripper unit 3 to move to the material picking position. The rotary electric gripper unit 3 picks up the PIN pins. After picking up the material, the multi-station rotary table 2 drives the rotary electric gripper unit 3 to rotate, which moves the electric gripper unit holding the workpiece to the appearance and size inspection station. The equipment automatically completes the workpiece quality inspection. PIN pins that fail the inspection are collected and processed at the NG station. Qualified PIN pins are moved to the subsequent pin insertion station as the multi-station rotary table 2 rotates, completing the overall PIN pin loading process.

[0022] Please see Figure 6 Two limiting grooves 10 are located on the bottom side inside the two linear feeding units 6 respectively. The limiting grooves 10 are arranged parallel to the PIN needle conveying direction of the feeding channel 9. The groove body is recessed inward to form a receiving space. The top of the limiting groove 10 is connected to the feeding channel 9 through the chip discharge through hole 11. The collection box 12 is located inside the limiting groove 10. The collection box 12 is an open pull-out rectangular box used to collect debris inside the feeding channel 9.

[0023] The specific usage method is as follows: various debris generated when the workpiece is conveyed and reversed in the feeding channel 9 is vertically dropped through the chip discharge through hole 11 under the vibration of the linear feeding unit 6 and directly falls into the collection box 12 placed in the limiting groove 10 for unified collection, reducing the impact of debris on the PIN pin; during production breaks, it is only necessary to pull out the collection box to clean up the debris, and after cleaning, it can be reset to continue production.

[0024] Working principle: During use, according to the diameter of the PIN needle to be processed by vibration feeding, manually rotate the second handle 716 to drive the connecting shaft 715 to rotate. Utilizing the linkage effect between the connecting shaft 715 and the two circular plates 713, the power is transmitted to the two circular plates 713. The two circular plates 713 will drive the rotating sleeve 711 and connecting block 712 to rotate through the connecting frame 714, compressing or releasing the torsion spring 708 and changing the preload of the torsion spring 708. For coarse needles, the torque of the torsion spring 708 is increased, enhancing the downward pressure component of the inclined seat 707 and ensuring stable 180° rotation of the reverse workpiece; for fine needles, the torque of the torsion spring 708 is reduced, increasing the upward buffer stroke of the inclined seat 707 and dispersing the pressure at the needle tip fulcrum. After adjustment, the electromagnetic self-locking unit is activated to lock the connecting shaft 715 to prevent vibration from loosening. Manually rotate the first handle 703 to drive the screw 702 to rotate. The rotation of the screw 702 drives the limit slider 704 to rise and fall vertically along the connecting seat 701, adjusting the height of the inclined seat 707 in the feeding channel 9 so that the inclined surface of the inclined seat 707 matches the outer wall of the PIN needle. After the adjustment is completed, stop rotating the first handle 703. After adjustment, the PIN needles are poured into the vibratory feeder 4. The vibratory feeder 4 drives the parts to be automatically sorted and oriented and conveyed to the feeding channel 9 of the linear feeding unit 6. When the PIN needles are conveyed to the feeding channel 9 in the forward direction (needle tip facing forward), the needle tip height first reaches the area of ​​the inclined seat 707. Under the continuous high-frequency direct vibration driving force of the linear feeding unit 6, the entire needle is laid flat and adheres to the soft pad at the bottom of the feeding channel 9, and is fed at a uniform speed along the center line of the feeding channel 9 towards the reversing area of ​​the inclined seat 707. The first part of the PIN needle to enter the coverage area of ​​the inclined seat 707 is the slender tip. The highest point of the tip is only H2, which just matches the passage gap formed by the bottom of the inclined seat 707 and the bottom surface of the feeding channel 9. The tip is directly embedded in the gap and slides forward smoothly along the bottom of the slope. After the tip of the PIN needle is completely delivered out of the inclined seat 707, the tail of the needle is delivered into the interior of the inclined seat 707. At this time, the height of the inclined seat 707 will not affect the delivery of the PIN needle. When the PIN needle is conveyed to the feeding channel 9 in the reverse direction (needle tail facing forward), the height of the thick needle tail of the PIN needle is relatively higher than that of the needle tip. The thick needle tail of the PIN needle contacts the front slope of the inclined seat 707 first. The inclined surface with a higher front and lower rear simultaneously applies downward pressure and backward resistance force to the needle tail. The needle tip of the PIN needle continuously adheres to the bottom surface of the channel to form a fixed rotation fulcrum. When the linear feeding unit 6 continuously pushes the PIN needle forward, the inclined seat 707 presses down on the needle tail under the action of the torsion spring 708. The workpiece rotates 180° in place in the closed channel with the needle tip as the fulcrum. During the rotation, the PIN needle pushes the inclined seat 707 and can float slightly upward to buffer the instantaneous impact and reduce the concentrated force on the needle tip. After the rotation is completed, the PIN needle switches to a needle tip facing forward posture and is smoothly conveyed out along the low gap of the inclined surface without leaving the feeding channel 9 throughout the entire process, and the conveying is uninterrupted. Various debris generated during the conveying and reversing of the workpiece in the feeding channel 9 is vertically dropped through the chip discharge through hole 11 under the vibration of the linear feeding unit 6 and directly falls into the collection box 12 placed in the limiting groove 10 for unified collection, thereby reducing the impact of debris on the PIN pin. The multi-station rotary table 2 drives the rotary electric gripper unit 3 to move to the material picking position. The rotary electric gripper unit 3 picks up the PIN pins. After picking up the PIN pins, the multi-station rotary table 2 drives the rotary electric gripper unit 3 to rotate and move to the subsequent inspection station. The NG station collects and processes the unqualified PIN pins, while the qualified PIN pins are moved to the subsequent pin insertion station as the multi-station rotary table 2 rotates, completing the overall PIN pin loading process.
