Description

Technical Field

[0001] This invention belongs to the field of vibration feeding technology, and particularly relates to a flexible vibratory feeder automatic correction feeding mechanism. Background Technology

[0002] As the core conductive component of electronic connectors, power plugs, signal terminals and other products, PIN pins are small in size and require high precision. In automated production processes such as injection molding, terminal crimping and connector assembly, they usually need to be transported in an orderly manner, with posture correction and directional queuing achieved by a special feeding mechanism to meet the material handling and processing requirements of high-speed and high-precision automated equipment.

[0003] According to Chinese Patent Publication No. CN210362181U, a multi-PIN feeding mechanism is disclosed, including a first vibratory plate, a second vibratory plate, a third vibratory plate, a feeding seat, and a feeding cylinder. The first vibratory plate corresponds to the first feeding groove of the feeding seat via a first feeding track. The second vibratory plate corresponds to the second feeding groove of the feeding seat via a second feeding track. The third vibratory plate corresponds to the third feeding groove of the feeding seat via a third feeding track. A feeding cylinder is also provided on the rear side of the feeding seat.

[0004] However, the above solution has the following drawbacks due to the use of a traditional rigid vibratory feeder with a fixed track and cylinder push rod for feeding: it cannot dynamically adapt to the specifications of the PIN pins, and the high-frequency rigid vibration can easily cause impact damage to small, thin-walled or surface-plated PIN pins, leading to deformation, bending, plating peeling or even breakage. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that during use, it is impossible to dynamically adapt to the specifications of the PIN pins, and high-frequency rigid vibration can easily cause impact damage to small, thin-walled or surface-plated PIN pins, leading to deformation, bending, plating peeling or even breakage. Therefore, a flexible vibratory feeder automatic correction feeding mechanism is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic deviation correction and feeding mechanism for a flexible vibratory feeder includes a base and a fixed box. The bottom of the fixed box is fixedly connected to the top of the base via a support frame. A vibratory feeder is disposed above the fixed box, and a material tray is disposed on the top surface of the vibratory feeder. A camera assembly is disposed on one side above the material tray. The mechanism also includes: The flexible vibration assembly includes a connecting seat fixedly connected to the bottom surface inside the fixed box, an eccentric vibration motor fixedly connected to the top of the connecting seat, and one end of the output shaft of the eccentric vibration motor fixedly connected to the center of the bottom of the vibrating material seat. Four sets of first fixed seats are symmetrically arranged on both sides of the connecting seat. Each set of first fixed seats consists of two first fixed seats, and a sliding frame is rotatably connected between the two first fixed seats. Four sets of second fixed seats are symmetrically arranged in pairs on both sides of the bottom of the vibrating material seat. Each set of second fixed seats consists of two first fixed seats. A connecting block is rotatably connected between the two second fixed seats. The side of the connecting block away from the second fixed seat extends into the sliding frame and is equipped with a spring.

[0007] As a further description of the above technical solution: The flexible vibration assembly also includes: The connecting block is slidably connected inside the sliding frame, and a sealing slip ring is fixedly connected to the side of the sliding frame away from the first fixed seat. The sealing slip ring is sleeved on the outside of the connecting block. Each of the multiple sliding frames has a limit hole on one side of its opposite side.

[0008] As a further description of the above technical solution: The flexible vibration assembly also includes: Four sliding blocks are slidably connected inside four sliding frames. The two sides of each sliding block are fixedly connected to one side of a connecting block and one end of a spring, respectively. A rectangular slider is fixedly connected to the end of the spring away from the connecting block.

[0009] As a further description of the above technical solution: A parallel adjustment component is provided on one side inside the sliding frame. The parallel adjustment component includes: Four lead screws are rotatably connected to the inside of four sliding frames, and the other end of each lead screw is connected to a lead screw sleeve. The end of the lead screw sleeve away from the lead screw is fixedly connected to the outer wall of the sliding block.

[0010] As a further description of the above technical solution: The parallel adjustment component further includes: The first bevel gear is fixedly connected to the outer periphery of the lead screw. A second bevel gear is meshed with one side of the first bevel gear. A rotating shaft is fixedly connected inside the second bevel gear. The rotating shaft is rotatably connected inside the sliding frame, and the end of the rotating shaft away from the second bevel gear extends to the outside of the sliding frame and is fixedly connected to a rotating handle.

[0011] As a further description of the above technical solution: The parallel adjustment component further includes: The limiting slider is slidably connected inside the limiting through hole, and one side of the limiting slider is fixedly connected to the outer wall of the rectangular slider. Indicator needles are fixedly connected to both sides of the limiting slider.

[0012] As a further description of the above technical solution: Also includes: A first mounting base is provided on one side of the base, and a feeding unit is placed on the top surface of the first mounting base. The output end of the feeding unit is located on one side above the material tray.

[0013] As a further description of the above technical solution: Also includes: A needle-retrieving unit is fixedly connected to one side of the top of the base.

[0014] As a further description of the above technical solution: Also includes: A material retrieval slot is provided on one side of the inside of the material tray, and the material retrieval slot is located on the side opposite to the needle retrieval unit.

[0015] As a further description of the above technical solution: Also includes: A needle-picking gripper unit is provided on one side of the material tray, and the needle-picking gripper unit is located on the side away from the needle-picking unit.

[0016] Compared with existing technologies, the flexible vibratory feeder automatic correction and feeding mechanism that adopts the above technical solution has the following beneficial effects: 1. In this invention, a single eccentric vibration motor is used in conjunction with four sets of obliquely symmetrical elastic support structures. The rotational excitation force output by the motor can be decomposed into two orthogonal simple harmonic vibration components in the X and Y directions. The two components are superimposed to synthesize a stable and controllable horizontal elliptical motion trajectory. This trajectory enables the pins inside the tray to produce continuous, low-impact flexible sliding under the action of friction and inertial forces, avoiding the impact and collision caused to the small pins by the traditional rigid vibration method. It effectively prevents the deformation, bending or surface coating peeling of parts, and is especially suitable for feeding scenarios of thin-walled, high-precision or easily damaged pins. At the same time, the elliptical motion trajectory can continuously disperse the stacked pins, reduce material jamming and entanglement, make the feeding process more stable and reliable, and improve the feeding effect of the mechanism.

[0017] 2. In this invention, the initial compression of the springs in the two sets of inclined elastic support units can be precisely changed through the linkage adjustment mechanism of the handle, bevel gear, lead screw and slider, thereby adjusting the equivalent stiffness and stiffness difference of the two sets of supports, realizing flexible control of the major axis direction and the ratio of major and minor axes of the horizontal elliptical motion trajectory; by adjusting the support unit in the direction of the feeding groove to a lower stiffness, the amplitude of the vibration component in this direction is increased, providing sufficient sliding driving force for the PIN needle; by adjusting the support unit perpendicular to the direction of the feeding groove to a higher stiffness, the amplitude of the vibration component in this direction is reduced, suppressing the lateral movement and disordered swaying of the PIN needle in the material tray, so that the vibration trajectory is precisely matched with the direction of the feeding groove; this adjustment method enables the mechanism to adapt to PIN needle materials of different specifications and sizes, improves the directional conveying, automatic correction and queuing stability of the mechanism, and enhances the versatility and adaptability of the equipment.

[0018] 3. In this invention, a sealing slip ring with a lip structure is provided between the sliding frame and the rectangular slider to form a two-way sealing barrier, preventing dust, pin fragments and external environmental dust from entering the sliding pair gap. This avoids dust particles causing screw thread jamming, slider wear or reduced spring compression adjustment accuracy, ensuring stable and reliable elliptical vibration trajectory, reducing equipment maintenance frequency, extending the service life of the screw, slider and elastic support components, and reducing the long-term operating cost of the mechanism.

[0021] 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.

[0022] Please see Figures 1-7 This invention provides a technical solution: a flexible vibratory feeder automatic correction and feeding mechanism, including a base 1 and a fixed box 7. The bottom of the fixed box 7 is fixedly connected to the top of the base 1 by a support frame, serving as the load-bearing base of the overall vibratory mechanism to ensure the overall assembly strength and operational stability of the equipment. A vibrating material seat 6 is provided above the fixed box 7, and a material tray 4 is fixedly connected to the top surface of the vibrating material seat 6 by screws. A camera assembly 12 is provided on one side above the material tray 4. The mechanism also includes: The flexible vibration component 8 includes a connecting seat 803 fixedly connected to the center of the bottom surface inside the fixed box 7. An eccentric vibration motor 801 is fixedly connected to the top of the connecting seat 803. One end of the output shaft of the eccentric vibration motor 801 is fixedly connected to the center of the bottom of the vibrating material seat 6. The eccentric vibration motor 801 adopts a built-in eccentric block structure. The eccentric block rotates synchronously at high speed with the motor spindle. The centrifugal excitation force generated by the rotation of the eccentric block forms a continuous and stable rotational excitation source. Four sets of first fixed seats 804 are symmetrically arranged on both sides of the connecting seat 803. Each set of first fixed seats 804 consists of two first fixed seats 804. A sliding frame 805 is rotatably connected between the two first fixed seats 804 through a first pin, so that the sliding frame 805 can rotate around the first pin at a small angle adaptively, which has good swing adaptability and can adapt to the slight positional displacement during vibration, thus avoiding structural jamming. Four sets of second fixed seats 807 are symmetrically arranged in pairs on both sides of the bottom of the vibrating material seat 6. Each set of second fixed seats 807 consists of two first fixed seats 804. The two second fixed seats 807 are rotatably connected by a connecting block 806 through a second pin. The side of the connecting block 806 away from the second fixed seat 807 extends into the sliding frame 805 and is equipped with a spring 809. Vibration buffering and stiffness adjustment are achieved through the elastic deformation of the spring 809, thus constructing four sets of uniform and symmetrical elastic support systems to ensure the balance and stability of the overall vibration. Please see Figures 3-5 The flexible vibration assembly 8 also includes: The connecting block 806 is slidably connected inside the sliding frame 805, allowing for stable linear sliding along the cavity of the sliding frame 805, ensuring the guiding accuracy of the spring 809 during compression and rebound. A sealing slip ring 10 is fixedly connected to the side of the sliding frame 805 away from the first fixed seat 804. The sealing slip ring 10 is sleeved on the outside of the connecting block 806 and is an annular seal made of nitrile rubber / fluororubber with a dustproof lip. It is sleeved on the lead screw 901, lead screw sleeve 906, and rectangular slider 805. At the fit gap between 02 and the sliding frame 805, the inner lip of the sealing slip ring 10 is interference-fitted with the outer wall of the lead screw 901, and the outer lip is in close contact with the inner wall of the lead screw sleeve 906 / sliding frame 805. This can effectively prevent PIN needle dust, processing debris and external environmental dust in the material tray 4 from entering the sliding pair gap, avoid dust particles causing lead screw thread jamming and slider wear, ensure the accuracy and smoothness of spring 809 compression adjustment, and prevent elliptical trajectory deviation caused by adjustment mechanism jamming. Multiple sliding frames 805 have limit holes on one side of each other. Scales are provided on both sides of the limit holes. Operators can intuitively read the sliding stroke of the rectangular slider 802 and the compression value of the spring 809 through the scales, so as to achieve precise and quantitative fine-tuning operations and ensure the consistency of the adjustment of the four sets of elastic supports. The longitudinal cross-sectional shape of the limit holes is set to a rectangular structure. Four sliding blocks 808 are slidably connected inside four sliding frames 805 respectively. The two sides of the sliding blocks 808 are fixedly connected to one side of the connecting block 806 and one end of the spring 809 respectively. A rectangular slider 802 is fixedly connected to the end of the spring 809 away from the connecting block 806. The rectangular slider 802 can slide precisely along the inside of the sliding frame 805. By moving the position of the rectangular slider 802, the initial compression of the spring 809 can be precisely changed, thereby adjusting the equivalent stiffness of each set of elastic supports and realizing the controllable adjustment of the vibration trajectory. Please see Figure 1 It also includes: A first mounting base 2 is provided on one side of the base 1. A feeding unit 3 is placed on the top surface of the first mounting base 2. The output end of the feeding unit 3 is located on one side above the material tray 4, which can orderly and continuously transport batches of PIN needle materials into the material tray 4 to realize automated feeding operation. A needle-picking unit 11 is fixedly connected to one side of the top of the base 1 via a second mounting seat, serving as an actuator for material gripping and output; A material picking groove 5 is provided on one side of the inside of the material tray 4. The material picking groove 5 extends along the material conveying direction and is located on the side opposite to the needle picking unit 11. It is used to collect PIN needles with qualified posture, realize a single row of neat arrangement, and provide a stable material posture for precise clamping. A needle-picking gripper unit 13 is provided on one side of the material tray 4. The needle-picking gripper unit 13 is placed on the outer bottom surface through the third mounting base. The needle-picking gripper unit 13 is located on the side away from the needle-picking unit 11. It completes the material picking and placing, and transfer connection operations respectively, realizing the fully automated process of PIN needle feeding, gripping and output, effectively improving the automation level and production efficiency of the overall equipment.

[0023] The specific usage method and working principle are as follows: The feeding unit 3 orderly conveys the scattered PIN needle material into the tray 4. The eccentric vibration motor 801 is started. The eccentric vibration motor 801 generates centrifugal excitation force by rotating at high speed with the built-in eccentric block. Its output shaft will directly drive the vibrating material seat 6 and the tray 4 to rotate and vibrate. At this time, the four sets of obliquely arranged sliding frames 805, springs 809 and connecting blocks 806 around the vibrating material seat 6 form a symmetrical elastic constraint structure, which decomposes the rotational excitation force of the eccentric vibration motor 801 into two orthogonal simple harmonic vibration components X and Y. The two components are superimposed to form a horizontal elliptical motion trajectory, so that the vibrating material seat 6 and the tray 4 form a stable and controllable horizontal elliptical motion trajectory. This flexible vibration form provides a continuous and gentle sliding driving force for the PIN needles in the cavity, avoiding rigid impacts that could damage, deform or peel off the plating of the small PIN needles, thus protecting the appearance and performance of the precision small PIN needles. Under the continuous action of elliptical vibration, the PIN needles inside the material tray 4 tend to slide in a directional manner along the major axis of the ellipse due to friction and inertia. The material tray 4 is equipped with a picking groove 5 extending along the major axis of the ellipse. The width of the groove is adapted to the diameter of the PIN needles. PIN needles with the correct posture slide into the picking groove 5 and form a single row of neat arrangement. PIN needles with the wrong posture are blocked by the groove wall and return to the middle of the material tray 4 to continue to participate in elliptical vibration to correct their posture. Finally, under the visual positioning guidance of the camera component 12, the PIN needles that have entered the picking groove 5 are accurately determined by the system based on the material position and posture. Then, the picking unit 11 accurately picks them up and transports them to the next station, realizing a fully automatic and low-damage feeding process.

[0024] Please see Figures 6-7 A parallel adjustment component 9 is provided on one side inside the sliding frame 805. The parallel adjustment component 9 includes: Four lead screws 901 are rotatably connected inside four sliding frames 805 respectively. The other end of the lead screw 901 is connected to a lead screw sleeve 906. The end of the lead screw sleeve 906 away from the lead screw 901 is fixedly connected to the outer wall of the sliding block 808. Relying on the threaded transmission pair structure, the rotational motion of the lead screw 901 is converted into linear displacement, which drives the rectangular slider 802 to move synchronously. The first bevel gear 902 is fixedly connected to the outer periphery of the lead screw 901. The first bevel gear 902 is meshed with the second bevel gear 903 on one side. The second bevel gear 903 is fixedly connected to the rotating shaft 904 inside. The rotating shaft 904 is rotatably connected to the inside of the sliding frame 805. The end of the rotating shaft 904 away from the second bevel gear 903 extends to the outside of the sliding frame 805 and is fixedly connected to the handle 905. A limiter is sleeved on the outer periphery of the rotating shaft 904. The limiter is an IMAOBJ211-08001 miniature adjustable limiter, which consists of a limit sleeve, a positioning retaining ring and a locking screw. It can achieve precise limiting and locking at any angle to prevent the rotating shaft 904 from exceeding the limit. This technology is existing technology, so it will not be elaborated on further. The limiting slider 907 is slidably connected inside the limiting through hole, and one side of the limiting slider 907 is fixedly connected to the outer wall of the rectangular slider 802. Indicator needles 908 are fixedly connected to both sides of the limiting slider 907. The indicator needles 908 and the limiting through hole are perpendicular to each other. With the help of the scale on both sides of the limiting through hole, the moving distance of the rectangular slider 802 and the compression stroke of the spring 809 can be displayed intuitively, which is convenient for operators to make quantitative references, ensure the uniformity of the support adjustment parameters of each group, and improve the accuracy of trajectory adjustment.

[0025] The specific usage method and working principle are as follows: Manually operate the handle 905 as needed. The handle 905 rotates the shaft 904, causing the second bevel gear 903 to rotate. Utilizing the linkage effect between the second bevel gear 903 and the first bevel gear 902, power is transmitted to the first bevel gear 902. The first bevel gear 902 then drives the lead screw 901 to rotate. Then, utilizing the linkage effect between the lead screw 901 and the lead screw sleeve 906, power is transmitted to the lead screw sleeve 906. The lead screw sleeve 906 then drives the rectangular slider 802 to move, adjusting the initial compression of the spring 809. This synchronously changes the initial compression and equivalent stiffness of the four sets of springs 809. By synchronously adjusting the two sets of oblique supports to create a stiffness difference, the ratio of the major axis to the minor axis of the ellipse can be controlled. The support unit facing the material feeding groove 5 is adjusted to a lower stiffness, increasing the amplitude of the vibration component in that direction and providing sufficient sliding driving force for the PIN needle, ensuring stable material conveying along the material feeding groove 5. The support unit perpendicular to the material feeding groove 5 is adjusted to a higher stiffness, reducing the amplitude of the vibration component in that direction and suppressing the lateral movement and disordered oscillation of the PIN needle within the material tray 4. Ultimately, the sliding trajectory of the PIN needle is perfectly matched with the direction of the material feeding groove 5, ensuring that the PIN needle is conveyed to the feeding end in a stable posture and continuously, providing reliable assurance for subsequent visual positioning and clamping processes. At the same time, a sealing slip ring 10 is provided between the sliding frame 805 and the rectangular slider 802, which can effectively prevent dust from entering the sliding pair gap, avoiding dust particles causing screw thread jamming and slider wear, ensuring the accuracy and smoothness of spring 809 compression adjustment, and preventing elliptical trajectory deviation caused by adjustment mechanism jamming.

[0026] Working principle: During use, the feeding unit 3 conveys the PIN needle material into the tray 4 and starts the eccentric vibration motor 801. The output shaft of the eccentric vibration motor 801 directly drives the vibrating base 6 and the tray 4 to rotate and vibrate. At this time, the four sets of obliquely arranged sliding frames 805, springs 809 and connecting blocks 806 set around the vibrating base 6 form a symmetrical elastic constraint structure, which decomposes the rotational excitation force of the eccentric vibration motor 801 into two orthogonal simple harmonic vibration components X and Y. The two components are superimposed to form a horizontal elliptical motion trajectory, so that the vibrating base 6 and the tray 4 form a stable and controllable horizontal elliptical motion trajectory, providing continuous, low-impact flexible sliding force for the PIN needles inside the tray 4, avoiding rigid impact from causing damage, deformation or plating peeling to the small PIN needles; Under the continuous action of elliptical vibration, the PIN pins inside the material tray 4 tend to slide in a directional manner along the major axis of the ellipse due to friction and inertia. The material tray 4 is provided with a picking groove 5 extending along the major axis of the ellipse. The width of the groove is adapted to the diameter of the PIN pins. PIN pins with the correct posture slide into the picking groove 5 and form a single row of neat arrangement. PIN pins with the wrong posture are blocked by the groove wall and return to the middle of the material tray 4 to continue to participate in elliptical vibration to correct their posture. Finally, the PIN pins that have entered the picking groove 5 are accurately picked up by the picking unit 11 and transported to the next station under the visual positioning guidance of the camera component 12, realizing a fully automatic and low-damage feeding process. Prior to this, the handle 905 is manually operated as needed. The handle 905 drives the second bevel gear 903 to rotate by rotating the shaft 904. The power is transmitted to the first bevel gear 902 by utilizing the linkage effect between the second bevel gear 903 and the first bevel gear 902. The first bevel gear 902 drives the lead screw 901 to rotate. Then, the power is transmitted to the lead screw sleeve 906 by utilizing the linkage effect between the lead screw 901 and the lead screw sleeve 906. The lead screw sleeve 906 drives the rectangular slider 802 to move, adjusting the initial compression of the spring 809. This allows for the simultaneous change of the initial compression and equivalent stiffness of the four sets of springs 809. The stiffness difference between the two sets of inclined supports can be adjusted simultaneously, thereby controlling the direction of the major axis of the ellipse and the ratio of the major and minor axes. This ensures that the PIN needle is continuously fed to the picking end in a stable posture, providing a reliable guarantee for subsequent visual positioning and clamping processes. Meanwhile, a sealing slip ring 10 is provided between the sliding frame 805 and the rectangular slider 802, which can effectively prevent dust from entering the sliding pair gap, ensure the accuracy and smoothness of the spring 809 compression adjustment, and prevent the elliptical trajectory deviation caused by the jamming of the adjustment mechanism.
