Description

Technical Field

[0001] This invention relates to the field of assembly equipment, specifically to a cover feeding mechanism and an automatic assembly device. Background Technology

[0002] like Figure 1 The elastic component shown includes a base component, a spring component, and a top cover component. The base component is a hollow cylindrical structure with through holes on both side walls. The top cover component has protruding locking posts on both sides. The spring component elastically abuts against the base component and the top cover component, and is installed vertically. During assembly, the top cover component presses down on the spring component, causing the locking posts to insert into the corresponding through holes. Current assembly methods rely on manual assembly, resulting in low efficiency. Furthermore, the diameters of both the base and top cover components are approximately 8.5mm, meaning the elastic component is slightly smaller than a worker's finger, making it inconvenient for workers to handle and assemble, further reducing assembly efficiency.

[0003] Therefore, there is an urgent need for an assembly device that can automatically assemble this elastic component, including a top cover feeding mechanism. Existing feeding mechanisms can complete one feeding action by lifting the workpiece with a vacuum suction cup and moving it onto the semi-finished component. However, since the top cover workpiece and the base workpiece of the semi-finished component need to be connected via a locking pin and a through-hole, the orientation of the top cover locking pin is critical, i.e., the placement direction of the top cover workpiece on the semi-finished component is critical. Existing feeding mechanisms have difficulty controlling the placement direction of the top cover workpiece, which may lead to the subsequent inability to connect and securely fix the top cover workpiece to the base workpiece. Summary of the Invention

[0004] The first objective of this invention is to provide a cover feeding mechanism that automatically picks up cover workpieces and can accurately control the orientation of the cover workpieces.

[0005] A second objective of the present invention is to provide an automatic assembly device that includes the above-described cover feeding mechanism.

[0006] To achieve the aforementioned first objective, the present invention provides a top cover feeding mechanism comprising a vibratory feeding assembly, a distributing assembly, a detection assembly, and a picking assembly. The vibratory feeding assembly is provided with a vibratory conveying channel extending along a first direction. The distributing assembly is located at the outlet end of the vibratory conveying channel and includes a distributing plate and a distributing drive device. The distributing plate has a distributing groove, and the distributing drive device drives the distributing plate to move back and forth along a second direction, which intersects with the first direction, so that the distributing groove and the vibratory conveying channel are intermittently connected. The detection assembly is located above the distributing assembly and includes a detector that emits detection light upwards towards the distributing groove. The picking assembly is located on one side of the distributing assembly and includes a picking mounting frame, a sliding seat, a lifting seat, a rotating assembly, and a suction component. The sliding seat is movably mounted on the picking mounting frame along the second direction, and the lifting seat is movably mounted on the sliding seat along the vertical direction. The rotating assembly and the suction component are both located on the lifting seat and above the detection assembly. The rotating assembly can drive the suction component to rotate around its own axis.

[0007] As can be seen from the above scheme, by setting up a suction component, the upper cover workpiece is picked up using the principle of vacuum adsorption. By setting up a detector, the detection light emitted by the detector is directed towards the part of the upper cover workpiece that protrudes from the suction component, which is used to detect whether the notch at the bottom of the upper cover workpiece is aligned with the detector side. This is beneficial to achieve accurate orientation of the upper cover workpiece and facilitates its alignment with the base workpiece. By setting up a rotating component, the suction component is driven to rotate around its own axis to adjust the swing direction of the upper cover workpiece, ensuring that the notch of the upper cover workpiece is aligned with the detector.

[0008] A further embodiment is that the suction component has a channel inside, which extends along the axial direction of the suction component. The lower part of the suction component has a suction groove, which is connected to the channel. The upper part of the suction component is connected to a rotary joint, which is connected to the channel inside the rotary joint.

[0009] A further embodiment is that the rotating assembly includes a rotating drive device and a drive gear, with the drive gear mounted on the rotating shaft of the rotating drive device; a driven gear is sleeved in the middle of the suction component, and the drive gear and the driven gear are meshed together.

[0010] As can be seen from the above scheme, the rotation of the suction component is driven by the meshing connection of gears, which enables the suction component to rotate smoothly, which is beneficial to improving the rotation accuracy and is especially suitable for small top cover workpieces.

[0011] A further embodiment includes a rotating fixed base, which is detachably connected to a lifting base. A rotating drive device is mounted on the rotating fixed base, and the rotating shaft of the rotating drive device is parallel to the suction component. The distance between the rotating fixed base and the lifting base is adjustable in the direction of the line connecting the driving gear and the driven gear.

[0012] As can be seen from the above scheme, by setting the distance between the rotating fixed seat and the lifting seat to be adjustable, the driving gear and the driven gear can be quickly adjusted to the most suitable position during installation and debugging, which facilitates installation and debugging operations and saves unnecessary time.

[0013] A further embodiment is that the rotating fixed base includes a support part, a first connecting part and a second connecting part, the support part is connected between the first connecting part and the second connecting part, and a cavity is formed between the support part and the first connecting part and the second connecting part; the rotating drive device is disposed on the first connecting part, the drive gear is disposed in the cavity, and the second connecting part is connected to the lifting base.

[0014] As can be seen from the above scheme, by setting a rotating fixed seat, the rotating drive device can be supported; by setting a cavity, the drive gear can be protected and foreign objects can be prevented from entering the drive gear.

[0015] A further embodiment includes a detection base, a detection drive sliding device, a detection moving seat, and a detection mounting seat. The detection drive sliding device and the detection moving seat are both mounted on the detection base. The detection drive sliding device can drive the detection moving seat to move upwards towards the material distribution trough. The detection mounting seat is mounted on the detection moving seat, and the detector is mounted on the detection mounting seat.

[0016] As can be seen from the above scheme, by setting up a detection drive sliding device, the distance between the detector and the workpiece on the upper cover can be adjusted according to the performance of the selected detector, thereby ensuring the accuracy of the detector detection.

[0017] A further improvement is that the relative position between the detection mounting base and the detection drive sliding device is adjustable in the direction of movement of the detection moving base; and the installation position of the detection base is adjustable in the direction of movement perpendicular to the detection moving base.

[0018] A further embodiment includes a material distribution assembly, a material distribution mounting frame, a surrounding plate, a material distribution drive device, and a stop plate. The surrounding plate is mounted on the material distribution mounting frame, and a clearance groove is provided in the middle of the surrounding plate. The material distribution drive device drives the material distribution plate to move back and forth within the clearance groove. The stop plate is located at the bottom of the material distribution plate, and the front end of the stop plate protrudes from the end wall of the material distribution plate. A passage is provided on one side of the surrounding plate. The first end of the passage is connected to the vibrating conveyor channel, and the second end of the passage is intermittently connected to the material distribution trough.

[0019] As can be seen from the above scheme, by setting up a material distribution trough, the batch of top cover workpieces that are continuously conveyed are separated one by one, making it convenient to pick up the workpieces.

[0020] A further solution is to provide a waste box on one side of the material handling component, with the waste box positioned below the suction component.

[0021] To achieve the second objective mentioned above, the present invention provides an automatic assembly device, including the aforementioned cover feeding mechanism. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] See Figure 1 and Figure 2The elastic component 1 includes a base workpiece 11, a spring workpiece 12, and a top cover workpiece 13. The base workpiece 11 is a hollow cylindrical structure. Two arc-shaped grooves 111 and two protrusions 112 are provided on the peripheral wall of the base workpiece 11, with the arc-shaped grooves 111 and protrusions 112 spaced apart. A through hole 1121 is formed on the protrusion 112 of the base workpiece 11, extending radially along the base workpiece 11. Three limiting stops 113 are provided on the inner wall of the base workpiece 11, protruding towards its center along the inner peripheral wall of the base workpiece 11. The top cover workpiece 13 is provided with a first mating protrusion 131 and a second mating groove 132. The first mating protrusion 131 mates with the arc-shaped grooves 111, and the second mating groove 132 mates with the protrusions 112. The upper cover workpiece 13 has a retaining post 133 disposed within the second mating groove 132. The retaining post 133 extends radially along the upper cover workpiece 13 and protrudes from the peripheral wall of the upper cover, for engaging with the through hole 1121. The upper cover workpiece 13 has a notch 134 on its lower peripheral wall, and the notch 134 and the retaining post 133 are spaced apart by a first preset angle θ1 in the circumferential direction of the upper cover workpiece 13. The spring workpiece 12 elastically abuts against the base workpiece 11 and the upper cover workpiece 13. Specifically, the spring workpiece 12 is disposed between three limiting stops 113 and supported by the limiting stops 113 to prevent the spring workpiece 12 from falling off the lower part of the base workpiece 11. During assembly, the upper cover workpiece 13 presses against the spring workpiece 12 until the retaining post 133 is inserted into the corresponding through hole 1121, achieving the assembly and engagement of the three components.

[0037] Example of an automated assembly device:

[0038] See Figures 3 to 5 and combined Figure 1 and Figure 2 The automatic assembly device provided in this embodiment includes a worktable 2 and a rotating mechanism 3, a base loading mechanism 4, a spring loading mechanism 5, a spring detection mechanism 6, and a top cover loading mechanism 7, all mounted on the worktable 2. The rotating mechanism 3 includes a rotating drive device, an indexing plate, and multiple tooling fixtures. The indexing plate has at least four workstations, evenly spaced and arranged sequentially along the rotation direction of the indexing plate: a base loading workstation, a spring loading workstation, a detection workstation, and a top cover loading workstation. The base loading mechanism 4, spring loading mechanism 5, spring detection mechanism 6, and top cover loading mechanism 7 are arranged sequentially around the rotating mechanism according to the assembly sequence of the elastic components 1, and are configured in conjunction with the corresponding workstations to facilitate assembly according to a preset procedure.

[0039] It should be noted that since the through hole 1121 on the base workpiece 11 needs to be connected with the locking post 133 on the upper cover workpiece 13, the base workpiece 11 and the upper cover workpiece 13 need to be oriented separately. In this embodiment, when the base feeding mechanism 4 is feeding, it oriented the line connecting the two through holes 1121 of the base workpiece 11 along the radial direction of the indexing plate (e.g., ...). Figure 5 (Solid arrow on the left side) As the indexing plate rotates clockwise, the base workpiece 11 passes through the spring loading station and the inspection station, and when it reaches the top cover loading station, the line connecting the two through holes 1121 of the base workpiece 11 is as follows: Figure 5 As shown by the dashed arrow on the lower middle side, when the upper cover workpiece 11 is being loaded, the line connecting the two locking posts 133 on it should also be as shown by the dashed arrow.

[0040] See Figures 6 to 8 and combined Figure 4 The upper cover feeding mechanism 7 includes a vibratory feeding component 71, a material distribution component 72, a detection component 73, and a material picking component 74.

[0041] The vibratory feeding assembly 71 includes a vibratory plate 711, a linear vibrator 712, and a vibratory conveying plate 713. The vibratory conveying plate 713 is disposed on the linear vibrator 712, and two vibratory conveying channels 7131 are formed on the vibratory conveying plate 713. The vibratory conveying channels 7131 extend along a first direction, and the inlet end of the vibratory conveying channel 7131 is connected to the outlet end of the vibratory plate 711. For convenience, in this embodiment, the first direction is designated as the X direction, the second direction as the Y direction, and the up-down direction as the Z direction.

[0042] The material distribution assembly 72 is disposed at the discharge end of the vibrating conveyor channel 7131. The material distribution assembly 72 includes a material distribution mounting frame 721, a surrounding plate 722, a material distribution plate 723, and a material distribution drive device 724. The surrounding plate 722 is disposed on the top wall of the material distribution mounting frame 721, and a clearance groove 7221 is provided in the middle of the surrounding plate 722. The material distribution plate 723 is disposed in the clearance groove 7221. The material distribution drive device 724 drives the material distribution plate 723 to move back and forth in the clearance groove 7221 along a second direction. The second direction intersects with the first direction. In this embodiment, it is preferred that the second direction is perpendicular to the first direction, that is, the second direction is the Y direction. The material distribution plate 723 has two material distribution slots 7231. The material distribution slots 7231 are slightly larger than one top cover workpiece 13, so that at most one top cover workpiece 13 can enter the material distribution slot 7231. Two passageways 7222 are provided on one side of the enclosure 722. The first end of the passageway 7222 is connected to the corresponding vibrating conveyor 7131, and the second end of the passageway 7222 is intermittently connected to the corresponding material distribution trough 7231. When the passageway 7222 is connected to the material distribution trough 7231, the upper cover workpiece 13 can enter the material distribution trough 7231. Then, the material distribution drive device 724 drives the material distribution plate 723 to move forward, so that the material distribution trough 7231 is misaligned with the passageway 7222. At this time, the upper cover workpiece 13 behind cannot enter the material distribution trough 7231. The upper cover workpiece 13 located in the material distribution trough 7231 is arranged independently, which is convenient for the material picking component 74 to pick up the material.

[0043] The material distribution assembly 72 also includes a stop plate 725, which is disposed at the bottom of the material distribution plate 723, and the front end of the stop plate 725 protrudes from the end wall of the material distribution plate 723. When the material distribution plate 723 moves forward, the stop plate 725 abuts against the groove wall of the clearance groove 7221 before the material distribution plate 723. The front end of the stop plate 725 may be provided with a buffer pad, or the stop plate 725 may be made of a buffer block to achieve a buffering effect.

[0044] See Figure 9 and Figure 10 and combined Figure 2 and Figure 7The detection component 73 is mounted on the material distribution mounting frame 721 and located above the material distribution component 72. In this embodiment, the detection component 73 is located on the side of the material distribution component 72 away from the vibrating conveyor channel 7131. The detection component 73 includes a detection base 731, a detection sliding drive device 732, a detection moving seat 733, a detection mounting base 734, and two detectors 735. The detection sliding drive device 732 and the detection moving seat 733 are both mounted on the detection base 731. The detection sliding drive device 732 can drive the detection moving seat 733 to move towards the material distribution channel 7231. The detection sliding drive device 732 is preferably a cylinder. The detection mounting base 734 is mounted on the detection moving seat 733. The two detectors 735 are arranged along a second direction on the detection mounting base 734. The detectors 735 emit detection light horizontally towards the material distribution channel 7231, and the direction of the detection light is parallel to the first direction. In this embodiment, the detectors 735 are preferably reflective fiber optic sensors. The detector 735 is used to detect whether the notch 134 of the cover workpiece 13 is aligned with the detector 735. If so, it means that the cover workpiece 13 has reached the first orientation position.

[0045] exist Figure 2 In this process, because the notch 134 of the upper cover workpiece 13 is spaced apart by a first preset angle θ1 from the locking post 133, after the upper cover workpiece 13 reaches the first positioning position, it needs to rotate by a second preset angle θ2. If this "rotation" is clockwise, then the second preset angle θ2 = 90° - θ1; ​​if this "rotation" is counterclockwise, then the second preset angle θ2 = 90° + θ1. Afterward, the upper cover workpiece 13 reaches the second positioning position, that is, the line connecting the two locking posts 133 on the upper cover workpiece 13 swings in the direction shown in the figure. Figure 5 As shown by the dashed arrow. Of course, in other embodiments, the orientation of the upper cover workpiece 13 can be set to other different states, such as the line connecting the two locking pins 133 of the upper cover workpiece 13 being parallel to the tangent of the indexing plate, as long as the upper cover workpiece 13 and the base workpiece 11 correspond to each other, which will not be elaborated here.

[0046] The relative position between the detection mounting base 734 and the detection sliding drive device 732 is adjustable in the moving direction of the detection moving base 733 (X-direction). Specifically, the detection mounting base 734 has multiple first elongated holes 7331, the length of which extends along the moving direction of the detection moving base 733. The detection sliding drive device 732 has a first connecting hole 7321. The detection mounting base 734 is connected to the detection sliding drive device 732 by bolts. These bolts pass through the first elongated holes 7331 and are connected within the first connecting holes 7321. The position of these bolts can be adjusted along the length of the first elongated holes 7331.

[0047] The installation position of the detection base 731 is adjustable in the moving direction of the vertical detection moving seat 733, i.e., upward (Y-direction). Specifically, the end of the detection base 731 is provided with a second elongated hole 7311, the length of which extends in a direction perpendicular to the moving direction of the detection moving seat 733. A second connecting hole (not shown in the figure) is provided on one side of the material distribution mounting frame 721. The detection base 731 is connected to the material distribution mounting frame 721 by bolts. The bolts pass through the second elongated hole 7311 and are connected in the second connecting hole. The position of the bolts can be adjusted along the length of the second elongated hole 7311.

[0048] See Figures 11 to 13 and combined Figure 4 and Figure 6 The material handling assembly 74 is disposed between the material dispensing assembly 72 and the indexing plate. The material handling assembly 74 includes a material handling mounting frame 741, a sliding seat 742, a lifting seat 743, a rotating assembly 744, and two suction members 745. The material handling mounting frame 741 extends along a second direction and is equipped with a material handling translation drive device 7411. The sliding seat 742 is disposed on the material handling mounting frame 741, and the material handling translation drive device 7411 drives the sliding seat 742 to move back and forth along the second direction. The lifting seat 743 is disposed on the sliding seat 742, and is equipped with a lifting drive device 7434, which drives the lifting seat 743 to move up and down relative to the sliding seat 742. The rotating assembly 744 and the two suction members 745 are both disposed on the lifting seat 743 and are both located above the detection assembly 73. The two suction members 745 are arranged along the sliding direction of the sliding seat 742, i.e., along the second direction. The rotating component 744 is disposed on one side of the suction member 745, and the rotating component 744 can drive the suction member 745 to rotate back and forth around its own axis.

[0049] Specifically, the lifting seat 743 includes a flat plate 7431, a first vertical plate 7432, and a second vertical plate 7433. The first vertical plate 7432 is vertically connected to a first end of the flat plate 7431 along its length, and the second vertical plate 7433 is vertically connected to the middle of the flat plate 7431, and is also perpendicular to the first vertical plate 7432. A first step 74311 and a second step 74312 are provided at the second end of the flat plate 7431. In the vertical direction, the first step 74311 is lower than the second step 74312.

[0050] The suction member 745 is rotatably mounted on the second step 74312, with its upper and lower ends protruding from the upper and lower sides of the second step 74312, respectively. A channel 7451 is formed inside the suction member 745, extending axially along its axis. A suction groove 7452 is formed at the lower part of the suction member 745, coaxially arranged and connected to the channel 7451 and the suction groove 7452. The suction groove 7452 is funnel-shaped, its depth being less than the height of the upper cover workpiece 13, causing the lower part of the upper cover workpiece 13 to protrude beyond the suction groove 7452. A rotary joint 748 is connected to the upper part of the suction member 745, which is connected to an external vacuum generator via an air pipe. This allows the suction member to both lift the upper cover workpiece 13 using vacuum adsorption and rotate back and forth around its own axis, thereby causing the upper cover workpiece 13 to rotate synchronously.

[0051] The rotating assembly 744 includes a rotating fixed base 7441, two rotating drive devices 7442, and two drive gears 7443. The rotating fixed base 7441 is detachably connected to the first step 74311. The rotating fixed base 7441 includes a support portion 74411, a first connecting portion 74412, and a second connecting portion 74413. The support portion 74411 is connected between the first connecting portion 74412 and the second connecting portion 74413, and a cavity 74414 is formed between the support portion 74411 and the first connecting portion 74412 and the second connecting portion 74413. An opening is provided on one side of the cavity 74414.

[0052] Both rotary drive devices 7442 are mounted on the first connecting portion 74412. The rotary drive device 7442 is preferably a motor. The rotation shaft of the rotary drive device 7442 is parallel to the suction member 745 and extends into the cavity 74414. A drive gear 7443 is disposed within the cavity 74414 and sleeved on the rotation shaft of the rotary drive device 7442. The drive gear 7443 at least partially protrudes from the opening of the cavity 74414 for meshing with the driven gear 747.

[0053] The distance between the rotating fixed seat 7441 and the lifting seat 743 is adjustable along the line connecting the driving gear 7443 and the driven gear 747. Specifically, the first step 74311 has an oblong hole, the length of which is parallel to the line connecting the driving gear 7443 and the driven gear 747. The second connecting part 74413 has a mounting hole. The rotating fixed seat 7441 is connected to the first step 74311 through a connector passing through the oblong hole and the mounting hole. The position of the connector within the oblong hole is adjustable.

[0054] exist Figure 6In the process, a waste frame 746 and four support columns are also provided on one side of the material picking component 74. The waste frame 746 is set at a height by supporting the frame and is located below the picking component 745 to receive defective products, such as top cover workpieces with missing gaps.

[0055] In summary, this invention utilizes a suction component to pick up the top cover workpiece using vacuum adsorption. A detector emits a detection light that is directed towards the portion of the top cover workpiece protruding from the suction component, detecting whether the notch at the bottom of the workpiece is aligned with the detector. This facilitates precise orientation of the top cover workpiece and allows for proper alignment with the base workpiece. Furthermore, a rotating component drives the suction component to rotate around its own axis, adjusting the orientation of the top cover workpiece and ensuring that the notch aligns with the detector.

[0056] Finally, it should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
