Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, specifically to a single-motor amplitude-modulating conveying mechanism and intelligent platform system. Background Technology

[0002] In automated production processes, workpieces typically require loading, conveying, lifting, and positioning. Traditional conveying mechanisms mainly consist of a base, a fixed frame, a movable frame, a conveying assembly, and an amplitude adjustment assembly. The conveying assembly transports the workpieces, while the amplitude adjustment assembly adjusts the distance between the fixed and movable frames. Because two separate power units are needed to power both the conveying and amplitude adjustment assemblies, the conveying mechanism is structurally complex, large in size, and occupies a significant amount of space. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a single-motor amplitude-regulating conveying mechanism and intelligent platform system. It enables the conveying component and amplitude-regulating component to share a single motor, eliminating a power unit compared to traditional methods, simplifying the structure of the conveying mechanism, resulting in a smaller size, less space occupation, lower cost, and easier promotion and use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A single-motor amplitude-adjusting conveying mechanism includes a base, on which a support component, a conveying component, an amplitude-adjusting component, and a drive motor are provided, wherein the conveying component and the amplitude-adjusting component are both connected to the drive motor for transmission.

[0006] The support assembly includes a fixed frame and a movable frame that can move relative to each other, and a conveying channel is formed between the fixed frame and the movable frame;

[0007] The amplitude adjustment component includes a clutch and a lead screw. The lead screw is rotatably connected to the movable frame. When the clutch is engaged, the lead screw can rotate, allowing the movable frame to move relative to the fixed frame along the axial direction of the lead screw. When the clutch is disengaged, the lead screw is stationary, and the drive motor only drives the conveying component. By setting up an amplitude adjustment component consisting of a clutch and a lead screw, the clutch's function of transmitting and separating power is utilized. This allows the motor to control the movement of the conveying component while simultaneously controlling the movement of the lead screw via the clutch. Thus, the conveying component and the amplitude adjustment component share a single motor. Compared to traditional methods, this eliminates a power unit, simplifies the structure of the conveying mechanism, reduces its size and space requirements, lowers costs, and facilitates widespread adoption.

[0008] As a preferred embodiment, the clutch includes an inner sleeve and an outer sleeve, the outer sleeve being connected to a drive motor, and the inner sleeve being connected to a lead screw, the lead screw being rotatable with the inner sleeve;

[0009] The inner sleeve is provided with multiple annularly distributed piston chambers, each containing a piston head. The inner sleeve is also provided with a reset mechanism that ensures the piston head always tends to converge and retract inward. The lead screw is provided with an air passage, and all of the piston chambers are connected to the air passage. Gas enters the piston chamber through the air passage, pushing the piston head outward to abut against the outer sleeve, so that the outer sleeve and the inner sleeve rotate synchronously.

[0010] As a preferred embodiment, the conveying channel is provided with a lifting assembly, which includes two lifting plates and a swing drive mechanism. The two lifting plates are slidably connected to a fixed frame and a movable frame, respectively. The swing drive mechanism includes a swing shaft and a rotary drive device for driving the swing shaft to rotate. The swing shaft is provided with two swing arms, which are rotatably connected to the corresponding lifting plates. The swing shaft drives the two swing arms to swing synchronously, so that the two lifting plates synchronously lift the workpiece in the conveying channel.

[0011] As a preferred embodiment, the fixed frame or movable frame is provided with a material blocking assembly, which includes a swinging component and a driving component. The swinging component is movably connected to the driving end of the driving component, and a spiral guide structure is provided between the driving end of the driving component and the swinging component. The driving component controls the rotation of the swinging component through the spiral guide structure, so that one end of the swinging component can rotatably extend into the conveying channel and block the workpiece in the conveying channel.

[0012] As a preferred embodiment, the clutch further includes a base, the lead screw is rotatably connected to the base, the base has an air chamber, the lead screw passes through the air chamber, and one end of the air passage has an air inlet hole communicating with the air chamber.

[0013] As a preferred embodiment, the outer sleeve is fitted outside the inner sleeve, and the outer sleeve has a receiving groove adapted to the inner sleeve. The circumferential inner sidewall of the receiving groove forms a friction surface corresponding to the piston head.

[0014] As a preferred embodiment, the outer sleeve is provided with a gear, which is coaxial with the axis of the outer sleeve, and the gear is connected to the main shaft of the drive motor via a synchronous belt.

[0015] As a preferred embodiment, the reset mechanism is an elastic rubber ring, which is sleeved on the inner sleeve, and all the piston heads are surrounded inside the elastic rubber ring, with the piston heads abutting against the inner sidewall of the elastic rubber ring.

[0016] As a preferred embodiment, the conveying assembly includes a drive shaft and two conveyor belts, both of which are disposed in the conveying channel and are respectively mounted on a fixed frame and a movable frame. The two conveyor belts are connected to a drive motor via the drive shaft.

[0017] An intelligent platform system includes a general frame mechanism, a functional head mechanism, a feeding mechanism, a detection mechanism, a calibration mechanism, and the single-motor amplitude modulation conveying mechanism;

[0018] The general rack mechanism includes a rack module and a main unit head module. The main unit head module is detachably mounted on the rack module and is electrically connected to the rack module.

[0019] The feeding mechanism includes several types of feeding devices for conveying workpieces, and the feeding devices can be detachably installed on a general frame mechanism;

[0020] The inspection mechanism includes an adjustable-height lower vision module for inspecting workpieces, and the inspection mechanism is mounted on a general frame mechanism. After the workpiece passes through the feeding mechanism, it enters the inspection mechanism for visual inspection.

[0021] The calibration mechanism includes a dispensing service platform for providing auxiliary services to the functional head mechanism, the dispensing service platform being mounted on a general-purpose rack mechanism;

[0022] The single-motor amplitude-modulating conveyor mechanism is used to convey workpieces and is installed on a general frame mechanism. The workpieces enter the conveyor mechanism after passing through the detection mechanism.

[0023] The functional head mechanism includes several working heads for dispensing glue, tearing film, or applying film. The functional head mechanism can be detachably installed on a general frame mechanism. During the conveying of the workpiece by the single motor amplitude modulation conveyor mechanism, the functional head mechanism performs dispensing glue, tearing film, or applying film on the workpiece.

[0024] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, by setting an amplitude adjustment component consisting of a clutch and a lead screw, the clutch can transmit and separate power, so that the motor can control the movement of the lead screw while controlling the movement of the conveying component. This allows the conveying component and the amplitude adjustment component to share a single motor. Compared with the traditional method, this eliminates a power unit, simplifies the structure of the conveying mechanism, makes it smaller, occupies less space, and has a lower cost, making it easier to promote and use.

[0070] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0071] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0072] like Figure 1-13As shown, the present invention discloses a single-motor amplitude-adjusting conveying mechanism, including a base 10. The base 10 is provided with a support component 20, a conveying component 30, an amplitude-adjusting component 40, and a drive motor 50. The conveying component 30 and the amplitude-adjusting component 40 are both connected to the drive motor 50. The support component 20 includes a fixed frame 21 and a movable frame 22 that can move relative to each other. The movable frame 22 is slidably connected to the base 10. A conveying channel 23 is formed between the fixed frame 21 and the movable frame 22.

[0073] The conveying assembly 30 is disposed in the conveying channel 23. The drive motor 50 controls the movement of the conveying assembly 30 to move the workpiece in the conveying channel 23. Specifically, the conveying assembly 30 includes a drive shaft 31 and two conveyor belts 32. The drive shaft 31 is rotatably mounted on the base 10, and the axis of the drive shaft 31 is perpendicular to the movement direction of the movable frame 22. The movable frame 22 has clearance holes (not shown) for the drive shaft 31 to pass through. Both conveyor belts 32 are disposed in the conveying channel 23, and are respectively mounted on the fixed frame 21 and the movable frame 22. The conveyor belts 32 are connected to the drive shaft 31 via the drive motor 50. Specifically, the cross-section of the drive shaft 31 is a regular polygon. Two synchronous pulleys 311 are fitted onto the drive shaft 31. Each synchronous pulley 311 has an axially extending regular polygonal hole (not shown). The synchronous pulleys 311 are axially movable on the drive shaft 31 through the regular polygonal hole. The two conveyor belts 32 are connected to the drive shaft 31 via the synchronous pulleys 311. That is, the drive motor 50 drives the synchronous pulleys 311 to rotate via the synchronous belts. The rotation of the synchronous pulleys 311 drives the drive shaft 31 to rotate. The rotation of the drive shaft 31 drives the conveyor belts 32 to transport workpieces. When the distance between the movable frame 22 and the fixed frame 21 is adjusted, the conveyor belts 32 will move along with the movable frame 22, and the conveyor belts 32 will drive the corresponding synchronous pulleys 311 to move along the axis of the drive shaft 31.

[0074] like Figure 1-6 As shown, the amplitude adjustment assembly 40 includes a clutch 49 and a lead screw 42, which is rotatably connected to the movable frame 22. When the clutch 49 is engaged, the drive motor 50 controls the lead screw 42 to rotate via the clutch 49, so that the movable frame 22 is relative to the fixed frame 21 along the axial direction of the lead screw 42, thereby adjusting the distance between the fixed frame 21 and the movable frame 22. When the clutch 49 is disengaged, the lead screw is stationary, and the drive motor 50 only drives the conveying assembly 30 to work.

[0075] The clutch 49 includes a base 41, an inner sleeve 43, and an outer sleeve 48. A gear 483 is mounted on the outer sleeve 48, coaxially with the axis of the outer sleeve 48, and integrally formed with the outer sleeve 48. Specifically, the clutch 49 is located within the conveying channel 23 and mounted on the side wall of the fixing frame 21. The axial direction of the outer sleeve 48 is perpendicular to the extending direction of the fixing frame 21. The gear 483 is positioned along the moving path of the conveyor belt 32. In the radial direction, the gear 483 is connected to the conveyor belt 32 on the fixed frame 21. The conveyor belt 32 on the fixed frame 21 passes through the synchronous pulley 311 and the gear 483 in sequence. In this embodiment, the gear 483 can also be connected to the drive motor 50 by another separate conveyor belt 32. The lead screw 42 is rotatably connected to the base 41. The inner sleeve 43 is connected to the lead screw 42. The lead screw 42 can rotate with the inner sleeve 43. The axes of the outer sleeve 48, the inner sleeve 43 and the lead screw 42 are coaxially arranged. Understandably, when the clutch 49 is in the engaged state, the inner circumferential wall of the outer sleeve 48 abuts against the outer circumferential wall of the inner sleeve 43, so that the outer sleeve 48 can drive the inner sleeve 43 to rotate synchronously, and the inner sleeve 43 drives the lead screw 42 to rotate synchronously; when the clutch 49 is in the disengaged state, there is a gap between the inner circumferential wall of the outer sleeve 48 and the outer circumferential wall of the inner sleeve 43, so that the outer sleeve 48 can rotate relative to the inner sleeve 43, and at this time neither the inner sleeve 43 nor the lead screw 42 rotates.

[0076] The inner sleeve 43 is provided with a piston cavity for accommodating a piston head 45. The piston cavity includes a plurality of piston head accommodating cavities 44, which are interconnected and arranged in a ring. For example, the present invention includes three piston head accommodating cavities 44, which are arranged in a ring around the central axis of the inner sleeve 43. A piston head 45 is provided in each piston head accommodating cavity 44. The piston head 45 is made of Teflon material. By using Teflon material, the piston head 45 has good wear resistance, which slows down the wear of the piston head 45, extends its service life, and avoids frequent replacement of the piston head 45. A sealing ring 451 is provided on the circumferential outer wall of the piston head 45. The outer wall of the sealing ring 451 is sealed to the piston head. The inner wall of the receiving cavity 44 abuts against the inner sleeve 43, which is also provided with a reset mechanism that makes the piston head 45 always have a radial inward tendency to retract. The reset mechanism is an elastic rubber ring 46, which is sleeved on the inner sleeve 43. All the piston heads 45 are surrounded by the elastic rubber ring 46, and the piston head 45 abuts against the inner wall of the elastic rubber ring 46. The outer circumferential wall of the inner sleeve 43 is provided with multiple annularly distributed arc-shaped grooves 431. Each arc-shaped groove 431 is correspondingly provided between two adjacent piston head receiving cavities 44, and the two ends of each arc-shaped groove 431 are respectively connected to two adjacent piston head receiving cavities 44. Each piston head 45 is provided with a groove 452, which penetrates the outer wall of the piston head 45. The end face and circumferential sidewalls are connected by the grooves 452 between adjacent arc-shaped grooves 431. Multiple arc-shaped grooves 431 and multiple grooves 452 are sequentially connected to form a complete annular groove. The elastic rubber ring 46 is disposed in the annular groove. For example, in this invention, the arc-shaped groove 431 is provided in three segments. Multiple annularly distributed arc-shaped grooves 431 are provided on the circumferential outer sidewall of the inner sleeve 43. The two ends of each arc-shaped groove 431 are respectively connected to two adjacent piston head receiving cavities 44. And a groove 452 is provided on the piston head 45. Adjacent arc-shaped grooves 431 are connected by the grooves 452, so that the arc-shaped grooves 431 and the grooves are sequentially connected to form a complete annular groove. The reset mechanism uses an elastic rubber ring 46. The six piston heads 45 can be synchronously reset by fitting them into the annular groove. The layout is reasonable and the assembly is convenient. It makes full use of the installation space of the inner sleeve 43, resulting in a more compact structure that is conducive to miniaturization. At the same time, the inner sleeve 43 and piston heads 45 are easy to process and have low processing costs. A limiting step 442 is formed on the inner side of the piston head receiving cavity 44 near the central axis of the inner sleeve 43. The limiting step 442 restricts the piston head 45 from retracting inward. By setting the limiting step 442, the elastic rubber ring 46 restricts the piston head 45 from retracting further inward when tightening it. When power transmission is not required, the two ends of the piston head 45 are clamped between the limiting step 442 and the elastic rubber ring 46, which can prevent the piston head 45 from loosening and ensure good stability.

[0077] The lead screw 42 is provided with an air passage 421, which extends along the axial direction of the lead screw 42. Multiple piston head receiving cavities 44 are connected to the air passage 421. Gas enters the piston head receiving cavity 44 through the air passage 421, pushing the piston head 45 radially outward to abut against the outer sleeve 48, so that the outer sleeve 48 can drive the inner sleeve 43 to rotate synchronously. The outer sleeve 48 has a receiving groove 481 adapted to the inner sleeve 43. During assembly, the inner sleeve 43 is fitted into the receiving groove 481, and a gap is maintained between the circumferential outer wall of the inner sleeve 43 and the circumferential inner wall of the receiving groove 481. When the clutch 49 is in the pressed state... When the clutch 49 is disengaged, the piston head 45 extends outward, and the outer end of the piston head 45 abuts against the circumferential inner wall of the receiving groove 481. When the clutch 49 is disengaged, the piston head 45 retracts inward, and a gap is maintained between the outer end of the piston head 45 and the circumferential inner wall of the receiving groove 481. The circumferential inner wall of the receiving groove 481 forms a friction surface 482 corresponding to the piston head 45. A toothed surface 453 is formed on the side of the piston head 45 facing the friction surface 482. By setting the toothed surface 453, the friction between the piston head 45 and the outer sleeve 48 is increased, making the piston head 45 and the outer sleeve 48 abut more tightly and with good stability.

[0078] The base 41 has an air chamber 411, and the lead screw 42 passes through the air chamber 411. One end of the air passage 421 has an air inlet 422 communicating with the air chamber 411. The base 41 has an air inlet 412 communicating with the air chamber 411. The air inlet 412 has an air pipe connector 413 communicating with an external air supply device. When the external air supply device supplies air, the trigger clutch 49 is in a pressed state. When the external air supply device stops supplying air, the trigger clutch 49 is in a released state. In the open state; both ends of the air chamber 411 are provided with a first sealing ring 414, and both first sealing rings 414 are sleeved on the lead screw 42. The air inlet hole 422 is located between the two first sealing rings 414. The lead screw 42 is rotatably connected to the base 41 through ball bearings 415. Specifically, there are two ball bearings 415, which are located on both sides of the air chamber 411, and the two first sealing rings 414 are located between the two ball bearings 415.

[0079] The inner sleeve 43 has a shaft hole 432 adapted to the lead screw 42. The inner sleeve 43 is sleeved on the lead screw 42 through the shaft hole 432. The other end of the air passage 421 has an air outlet hole 423 communicating with the shaft hole 432. One end of each of the plurality of piston head receiving cavities 44 is communicating with the shaft hole 432. The end of the piston head receiving cavity 44 away from the shaft hole 432 penetrates the circumferential outer side wall of the inner sleeve 43 to form a clearance opening 441. The clearance opening 441 allows the piston head 45 to extend outward.

[0080] One end of the inner sleeve 43 is formed with a non-circular positioning hole 433 communicating with the shaft hole 432, and one end of the lead screw 42 is formed with a non-circular positioning block 424. The cooperation between the non-circular positioning hole 433 and the non-circular positioning block 424 restricts the rotation of the inner sleeve 43 relative to the lead screw 42. The inner diameter of the non-circular positioning hole 433 is smaller than the inner diameter of the shaft hole 432, and a positioning boss (not shown) is formed between the non-circular positioning hole 433 and the shaft hole 432. The non-circular positioning block 424 is provided with a positioning recess 425 that matches the positioning boss. By setting the positioning boss and the positioning recess 425, the assembly of the inner sleeve 43 and the lead screw 42 is positioned, and the relative rotation of the two is prevented.

[0081] The non-circular positioning block 424 is provided with an axial connection hole 426. The bolt 427 passes through the non-circular positioning hole 433 and the axial connection hole 426 to connect the inner sleeve 43 with the lead screw 42. A washer 428 is provided between the head of the bolt 427 and the inner sleeve 43. A second sealing ring 47 is provided between the opening edge of the non-circular positioning hole 433 and the washer 428. A third sealing ring 429 is provided between the end of the shaft hole 432 away from the second sealing ring 47 and the outer surface of the lead screw 42. The third sealing ring 429 is sleeved on the lead screw 42.

[0082] It should be noted that the present invention adopts a pneumatic drive method in which gas drives the piston head 45 to move, or a hydraulic drive method in which liquid drives the piston head 45 to move.

[0083] Working principle of amplitude modulation component 40: The drive motor 50 controls the conveyor belt 32 on the fixed frame 21 to drive the outer sleeve 48 to rotate. At the same time, the external air supply device controls the clutch 49 to be in a pressed state. At this time, the external air supply device is used to output air. The air output by the external air supply device passes through the air pipe joint 413, air inlet 412, air chamber 411, air inlet hole 422, air passage 421, and air outlet hole 423 in sequence before entering the piston head receiving cavity 44. The air pushes the piston head 45 to activate the piston. The plug 45 extends radially outward to overcome the elastic force of the elastic ring 46. The outer ends of the three piston heads 45 simultaneously abut against the friction surface 482 on the outer sleeve 48, so that the outer sleeve 48 can drive the inner sleeve 43 to rotate synchronously. The inner sleeve 43 will also drive the lead screw 42 to rotate synchronously. The rotation of the lead screw 42 drives the movable frame 22 to move, thereby achieving amplitude adjustment. Since the air inlet 422 is always connected to the air chamber 411, air can still enter the air passage 421 from the air chamber 411 when the lead screw 42 rotates.

[0084] When the external air supply device stops outputting air, the elastic rubber ring 46 will automatically tighten the three piston heads 45, causing the three piston heads 45 to synchronously converge radially inward and retract. The outer ends of the piston heads 45 will disengage from the friction surface 482. At this time, the outer sleeve 48 will not drive the inner sleeve 43 to rotate. The external air supply device stops outputting air, and the control clutch 49 is in a disengaged state. Understandably, even if the drive motor 50 controls the conveyor belt 32 to drive the outer sleeve 48 to rotate, since there is no air to push the piston heads outward, the outer sleeve 48 will rotate relative to the inner sleeve 43. Neither the inner sleeve 43 nor the lead screw 42 will rotate. At this time, the drive motor 50 will only drive the conveyor assembly 30 to work.

[0085] By setting multiple annularly distributed piston head receiving cavities 44 and a reset mechanism on the inner sleeve 43, a piston head 45 is set in the piston head receiving cavity 44, and an air passage 421 is set in the lead screw 42. The air passage 421 is connected to the piston head receiving cavity 44. Gas enters the piston head receiving cavity 44 through the air passage 421 and pushes the piston head 45 outward to abut against the outer sleeve 48 to realize power transmission. The reset mechanism causes the piston head 45 to converge inward and retract to realize power separation. The piston head 45 is driven by air pressure to achieve frictional pressing and tight contact. The piston head 45 is annularly distributed in the inner sleeve 43, making the inner sleeve 43 structure more compact, simplifying the structure of the clutch 49 and reducing its volume. At the same time, the piston head 45 can be miniaturized, lightweight, and has good mobility, which is conducive to air pressure drive, making the power transmission and separation speed fast and efficient.

[0086] like Figure 1 , Figure 7 and Figure 8 As shown, a lifting assembly 60 is provided in the conveying channel 23. The lifting assembly 60 includes two lifting plates 61 and a swing drive mechanism 62. The two lifting plates 61 are slidably connected to the fixed frame 21 and the movable frame 22 respectively. The swing drive mechanism 62 includes a swing shaft 63 and a rotary drive device 65 for driving the swing shaft 63 to rotate. A first swing arm 64 and a second swing arm (not shown) are provided at a distance on the swing shaft 63. The first swing arm 64 and the second swing arm extend in the same direction and are both perpendicular to the axial direction of the swing shaft 63. The first swing arm 64 and the second swing arm are rotatably connected to the corresponding lifting plate 61. The swing shaft 63 drives the first swing arm 64 and the second swing arm to swing synchronously so that the two lifting plates 61 synchronously lift the workpiece in the conveying channel 23.

[0087] The rotary drive device 65 includes a connecting rod 651 and a push drive unit 652. The push drive unit 652 is mounted on the lower surface of the base 10. The base 10 is provided with a clearance hole 653 for the connecting rod to move. The clearance hole 653 passes through the upper and lower surfaces of the base 10. One end of the connecting rod 651 passes through the clearance hole 653 and extends upward to connect with the swing shaft 33. The other end of the connecting rod 651 is rotatably connected to the drive end of the push drive unit 652. The push drive unit 652 controls the connecting rod 651 to rotate and drives the swing shaft 63 to rotate. Specifically, the push drive unit 652 is a cylinder. The direction of movement of the moving rod of the push cylinder is perpendicular to the axial direction of the swing shaft 63.

[0088] The first swing arm 64 and the second swing arm are both provided with a waist-shaped pin hole 641 at the end away from the swing shaft 63. The axial direction of the waist-shaped pin hole 641 is the same as the axial direction of the swing shaft 63. The lifting plate 61 is provided with a pin. The pin and the waist-shaped pin hole 641 cooperate to make the first swing arm 64 and the second swing arm rotatably connected to the corresponding lifting plate 61. The swing shaft 63 has a polygonal cross section. One end of the first swing arm 64 and the second swing arm is formed with a polygonal through hole (not shown). The first swing arm 64 and the second swing arm are sleeved on the swing shaft 63 through the polygonal through hole.

[0089] The fixed frame 21 has a clearance groove 67 on the side facing the conveying channel 23 for the movement of the first swing arm 64. The upper and lower sides of the clearance groove 67 are respectively formed by an upper stop 671 and a lower stop 672. The cooperation of the upper stop 671 and the lower stop 672 limits the extreme swing angle of the first swing arm 64, specifically 60°. It can be understood that the movable frame 22 also has a clearance groove 67 on the side facing the conveying channel 23 for the movement of the second swing arm. By setting the upper stop 671 and the lower stop 672, the extreme swing angles of the first and second swing arms are limited, preventing excessive rotation angles and preventing the lifting plate 61 from colliding with other structures and causing damage. Simultaneously, the first and second swing arms can be accommodated in the clearance groove 67, allowing for a smaller distance between the fixed frame 21 and the movable frame 22, resulting in more efficient space utilization and a more compact structure.

[0090] The two lifting plates 61 are slidably connected vertically to the fixed frame 21 and the movable frame 22, respectively. The fixed frame 21 and the movable frame 22 are each provided with vertically extending slide rails (not shown). The lifting plate 61 is provided with a sliding groove (not shown). The cooperation between the slide rail and the sliding groove allows the lifting plate 61 to be slidably connected vertically to the fixed frame 21 and the movable frame 22. Each lifting plate 61 is located between two conveyor belts 32. The upper end of the fixed frame 21 and the movable frame 22 is provided with a positioning baffle 66 extending toward the conveying channel 23. The two lifting plates 61 are located directly below the corresponding positioning baffle 66. The positioning baffle 66 extends along the conveying direction of the conveying channel 23. The lower surface of the positioning baffle 66 forms a positioning reference surface. The positioning reference surface is used to position the workpiece. When the lifting plate 61 lifts the workpiece, the upper surface of the workpiece is in contact with the positioning reference surface.

[0091] Working principle of lifting assembly 60: Two conveyor belts 32 transport the workpiece along the direction of the conveying channel 23. After the workpiece reaches the designated position, the push drive unit 652 controls the connecting rod 651 to rotate and drives the swing shaft 63 to rotate. The swing shaft 63 drives the first swing arm 64 and the second swing arm to swing upward. The first swing arm 64 and the second swing arm drive the two lifting plates 61 to move upward in a straight line, so that the two lifting plates 61 simultaneously lift the workpiece and clamp the two ends of the workpiece between the lifting plate 61 and the positioning baffle 66.

[0092] By setting up a swing drive mechanism 62 consisting of a swing shaft 63 and a rotary drive device 65, a first swing arm 64 and a second swing arm are respectively rotatably connected to two lifting plates 61 on the swing shaft 63. The rotary drive device 65 drives the swing shaft 63 to rotate, and the swing shaft 63 drives the first swing arm 64 and the second swing arm to swing synchronously, so that the two lifting plates 61 synchronously lift the workpiece in the conveying channel 23. The indirect lifting method using a power unit avoids workpiece damage and reduces production costs. At the same time, the lever action of the first swing arm 64 and the second swing arm can be matched with a small cylinder, which occupies little space and is conducive to miniaturization.

[0093] like Figure 1 as well as Figure 9-12As shown, the fixed frame 21 is provided with a baffle assembly 70. In this invention, the baffle assembly 70 can also be provided on the movable frame 23. The baffle assembly 70 is located on the output end side of the conveying channel 23. The fixed frame 21 is provided with a piston groove 77 and a pipe joint 771 communicating with the lower end of the piston groove 77. The pipe joint 771 is connected to an external air source. The upper end of the piston groove 77 penetrates the upper surface of the fixed frame 21. The baffle assembly 70 includes a swing member 71 and a driving member. The driving member includes the piston groove 77 and a baffle assembly 70. The piston rod 76 is located in the piston groove 77. The swing member 71 is movably connected to the piston rod 76. A spiral guide structure is provided between the piston rod 76 and the swing member 71. The piston rod 76 controls the rotation of the swing member 71 through the spiral guide structure, so that one end of the swing member 71 can rotatably extend into the conveying channel 23 and block the workpiece in the conveying channel 23. By setting a driving member composed of the piston groove 77 and the piston rod 76, the piston groove 77 is set inside the fixed frame 21, which has a reasonable spatial layout, occupies less external space, and has a more compact structure.

[0094] The spiral guide structure includes a spiral guide groove 761 and a guide pin 721 that cooperates with the spiral guide groove 761. The spiral guide groove 761 is provided on the piston rod 76, and the guide pin 721 is provided on the swing member 71.

[0095] The upper end of the piston rod 76 has a movable groove 762. The swing member 71 is rotatably disposed in the movable groove 762 via the connecting shaft 72. The spiral guide groove 761 is disposed on the outer side wall of the piston rod 76 and communicates with the movable groove 762. The spiral guide groove 761 extends spirally along the axial direction of the piston rod 76. The guide pin 721 is disposed on the outer side wall of the connecting shaft 72. During movement, the guide pin 721 slides along the spiral guide groove 761.

[0096] The swinging component 71 is located above the fixed frame 21, and the end of the swinging component 71 away from the connecting shaft 72 is provided with a downwardly protruding stop block 711. The fixed frame 21 is provided with a clearance notch 78 on the side facing the conveying channel 23 for the stop block 711 to extend into. The clearance notch 78 penetrates the upper surface of the fixed frame 21. By setting the clearance notch 78, the stop block 711 can be hidden in the clearance notch 78, which results in a reasonable spatial layout, compact structure, and small space occupation.

[0097] The upper end of the connecting shaft 72 is rotatably connected to the fixing frame 21 via a ball bearing 74. Specifically, the ball bearing 74 is installed in the opening at the upper end of the piston groove 77. The side wall of the connecting shaft 72 is provided with a radially outward protruding upper step 722. The lower surface of the ball bearing 74 abuts against the upper step 722. A retaining ring 75 is sleeved on the upper end of the connecting shaft 72. The lower surface of the retaining ring 75 abuts against the upper surface of the ball bearing 74. The fixing frame 21 is provided with a pressure pin 79 for fixing the ball bearing 74. Specifically, the pin head at the upper end of the pressure pin 79 presses against the outer edge of the upper end of the ball bearing 74. There are two pressure pins 79, located on both sides of the ball bearing 74. By setting the pressure pins 79, the pressure pins 79 press against the ball bearing 74, which can restrict the upward movement of the connecting shaft 72.

[0098] A return spring 73 is sleeved on the connecting shaft 72 to ensure that the piston rod 76 always has a downward tendency. The side wall of the connecting shaft 72 is provided with a radially outward protruding lower step 723. The upper end of the return spring 73 abuts against the end face of the lower step 723, and the lower end of the return spring 73 abuts against the upper end face of the piston rod 76.

[0099] The outer side wall of the piston rod 76 is provided with a guide post 763, and the side wall of the fixing frame 21 is provided with a vertically extending guide hole 772. The guide hole 772 communicates with the piston groove 77. During assembly, one end of the guide post 763 extends into the guide hole 772. The side wall of the fixing frame 21 is provided with a clearance groove 773 corresponding to the guide pin 721. The clearance groove 773 is located above the guide hole 772. The clearance groove 773 extends laterally and communicates with the piston groove 77. During assembly, one end of the guide pin 721 passes through the spiral guide groove 761 and extends into the clearance groove 773. The guide pin 721 and the clearance groove 773 cooperate to restrict the upward movement of the connecting shaft 72.

[0100] The working principle of the material blocking assembly 70: The conveyor belt 32 conveys the workpiece along the direction of the conveying channel 23. An external air source supplies air into the piston groove 77. The air pushes the piston rod 76 to move upward. The spiral guide groove 761 pushes the guide pin 721 to move. Under the restriction of the clearance groove 773, the guide pin 721 drives the connecting shaft 72 to rotate. The connecting shaft 72 drives the swing member 71 to rotate 90°, so that the material blocking block 711 extends into the conveying channel 23 to block the workpiece. When the external air source no longer supplies air into the piston groove 77, the return spring 73 pushes the piston rod 76 to move downward. This causes the spiral guide groove 761 to push the guide pin 721 to rotate in the opposite direction. The connecting shaft 72 then drives the swing member 71 to rotate in the opposite direction by 90°. The material blocking block 711 on the swing member 71 exits the conveying channel 23 and enters the clearance notch 78.

[0101] By setting a material blocking assembly 70 consisting of a swinging member 71 and a driving member, a spiral guide structure is set between the driving end of the driving member and the swinging member 71. The driving member controls the rotation of the swinging member 71 through the spiral guide structure, so that one end of the swinging member 71 rotates and extends into the conveying channel 23 and blocks the workpiece in the conveying channel 23. The material blocking setting adopts a rotation method instead of the traditional linear method, which makes the installation space occupied by the swinging member 71 and the driving member small, which is conducive to the miniaturization of the feeding and blocking mechanism.

[0102] like Figure 13 As shown, another embodiment of the present invention differs from the above embodiment in that another movable frame 22 is provided on the side of the movable frame 22 away from the fixed frame 21, and another conveying component 30, another amplitude adjustment component 40 and another drive motor 50 are also provided on the base 10. The other conveying component 30 and the other amplitude adjustment component 40 are both connected to the other drive motor 50 in a transmission manner. It can be understood that in another embodiment, the two amplitude adjustment components 40 are powered by the two drive motors 50 respectively, the two conveying components 30 are also powered by the corresponding drive motors 50, and the two movable frames 22 are adjusted by the two amplitude adjustment components 40 respectively.

[0103] like Figure 14 As shown, the present invention also discloses an intelligent platform system, including a general frame mechanism 80, a functional head mechanism 81, a feeding mechanism, a detection mechanism, a calibration mechanism, a cleaning mechanism, and the single-motor amplitude modulation conveying mechanism.

[0104] The general rack mechanism 80 includes a rack module 801 and a main head module 802. The main head module 802 is detachably mounted on the rack module 801 and is electrically connected to the rack module 801.

[0105] The feeding mechanism includes several feeding devices for conveying workpieces, and the feeding devices can be detachably installed on the general frame mechanism 80. Specifically, the feeding mechanism includes a screw feeding mechanism 82 and a flexible feeding device 83. The screw feeding mechanism 82 is used to convey screws, and the flexible feeding device 83 is used to shake the material apart so that the functional head mechanism 81 can grab it for subsequent assembly.

[0106] The inspection mechanism includes an adjustable-height lower vision module 84 for visual inspection, and the inspection mechanism is mounted on a general frame mechanism 80. The workpiece enters the inspection mechanism for visual inspection after passing through the feeding mechanism.

[0107] The calibration mechanism includes a dispensing service platform 85 for providing auxiliary services such as glue cleaning, height measurement and position calibration, and glue weighing to the functional head mechanism 81. The calibration mechanism is installed on the general frame mechanism 80.

[0108] The cleaning mechanism 86 is used to clean the functional head mechanism 81;

[0109] The single-motor amplitude-modulating conveyor mechanism is used to convey workpieces and is installed on the general frame mechanism 80. The workpiece enters the conveyor mechanism after passing through the detection mechanism.

[0110] The functional head mechanism 81 includes several working heads for dispensing glue, tearing film, or applying film. The functional head mechanism 81 can be detachably installed on the general frame mechanism 80. During the conveying of the workpiece by the single motor amplitude modulation conveyor mechanism, the functional head mechanism 81 dispenses glue, tears film, or applies film to the workpiece.

[0111] In summary, this invention, by setting up an amplitude adjustment component 40 composed of a clutch 49 and a lead screw 42, utilizes the power transmission and separation functions of the clutch 49 to enable the motor to control the movement of the conveying component 30 while simultaneously controlling the movement of the lead screw 42 via the clutch 49. This allows the conveying component 30 and the amplitude adjustment component 40 to share a single motor, eliminating a power unit compared to traditional methods, simplifying the structure of the conveying mechanism, resulting in a smaller size, less space occupation, lower cost, and easier widespread application. Furthermore, the lifting component, amplitude adjustment component, and conveying component are all arranged in the conveying channel, while the baffle component is arranged within the fixed frame and located on one side of the output end of the conveying channel. This fully utilizes the internal space of the conveying channel and the internal space of the fixed frame, resulting in a reasonable layout, compact structure, and small space occupation.

[0112] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technology of the present invention shall still fall within the scope of the technical solution of the present invention.
