Description

Technical Field

[0001] This invention belongs to the technical field of hook production equipment, and specifically relates to a hook body and plum blossom piece assembly system. Background Technology

[0002] As a common connector, the core of hook assembly lies in connecting the hook body 110 to the perforated piece 900. Specifically, as... Figure 18 As shown, the plum blossom-shaped piece 900 has an installation groove 910, and the installation groove 910 has a hook hole 920 in the middle. The hook body 110 includes a hook head end 111, a hook shank 112, and a hook tail end 113 in sequence. During assembly, the hook body 110 must first be placed on the plum blossom-shaped piece 900, and then the hook head end 111 is manually aligned and passed through the hook hole 920. Then the hook shank 112 is slid into the hook hole 920, and finally the hook tail end 113 is stably embedded in the installation groove 910.

[0003] Taking Chinese utility model patent CN214979007U as an example, this patent discloses a novel hook-type plum blossom assembly device. The device includes a plum blossom feeding track, a feeding bracket for supporting the track, and a hook assembly mounted on the track. The plum blossom feeding track uses a drive wheel to apply a continuous thrust to the entire column of plum blossoms to achieve continuous feeding; simultaneously, the hook feeding device uses a hook conveying track and pneumatic feeding grippers to achieve individual feeding of the hooks. This design has significant drawbacks: the continuous thrust applied by the drive wheel to the entire column of plum blossoms easily leads to the accumulation and compression of the plum blossoms on the track, especially during high-speed production, which can easily cause jamming, misalignment, or even workpiece damage. Furthermore, this prior art only discloses the individual feeding mechanism of the hooks and plum blossoms, but does not reveal in detail how the two are precisely assembled. Summary of the Invention

[0004] To address the shortcomings of existing technologies, a hook and plum blossom piece assembly system is proposed, which enables the plum blossom pieces to be fed one by one to avoid accumulation, and completes the precise assembly of the hook and plum blossom pieces through integrated design.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A hook and plum blossom-shaped assembly system, comprising: A plum blossom-shaped feeding assembly is used to convey plum blossom-shaped pieces arranged in sequence. A plum blossom-shaped piece limiting assembly is provided at the end of the plum blossom-shaped piece feeding assembly. The plum blossom-shaped piece limiting assembly realizes that the plum blossom-shaped pieces slide one by one to the plum blossom-shaped piece loading position through the alternating lifting and lowering limiting columns. A rotating disc is provided with several support slots for accommodating plum blossom pieces. Plum blossom pieces at the material level are transferred to the support slots through a plum blossom piece transfer assembly. A hook feeding assembly is used to transport sequentially arranged hooks to a hook transfer position. The hook feeding assembly is located downstream of the cloverleaf feeding assembly. The hook transfer assembly transfers the hooks at the hook transfer position to the cloverleaf position on the rotating disk. And a hook flipping assembly, used to flip the hook at the plum blossom plate, with the head end of the hook sliding into the mounting groove along the hook hole on the plum blossom plate, and the tail end of the hook embedded in the mounting groove.

[0006] The technical solution is further configured such that the plum blossom feeding assembly includes a plum blossom feeding channel disposed inside the feeding housing, and a plum blossom baffle is disposed at the end of the plum blossom feeding channel and on the outside of the feeding housing to form a plum blossom feeding position.

[0007] The technical solution is further configured such that the limiting post is mounted on the feeding housing via a limiting mounting seat, and the limiting post can be raised and lowered relative to the limiting mounting seat.

[0008] The technical solution is further configured such that the plum blossom piece transfer assembly includes a plum blossom piece transfer gripper and a plum blossom piece transfer swing arm. The plum blossom piece transfer gripper picks up the plum blossom pieces located on the material level of the plum blossom pieces and transfers them to the bearing groove under the swinging action of the plum blossom piece transfer swing arm.

[0009] The technical solution is further configured such that several of the bearing grooves are located on the same circumference, the shape of the bearing grooves is adapted to the shape of the protrusion on the back of the plum blossom piece, and the edge of the rotating disk is provided with a clearance groove that communicates with the bearing groove.

[0010] The technical solution is further configured such that the hook feeding assembly includes a hook conveying track and a hook receiving unit, with an inclined track between the two, and the lower end of the inclined track serving as the hook receiving position. The head end of the hook is hung on the hook conveying track and slides along the hook conveying track and the inclined track to the hook receiving position under the action of the vibrator, and is transferred to the hook transfer position through the hook receiving unit.

[0011] The technical solution is further configured such that a hook baffle and a lifting plate assembly are provided at the end of the hook conveying track. The hook baffle can swing relative to the hook conveying track to open or close the connecting channel between the hook conveying track and the inclined track. The lifting plate assembly can rise and fall relative to the hook conveying track to allow the hook located at the end of the hook conveying track to slide into the inclined track.

[0012] The technical solution is further configured such that the hook receiving unit includes a receiving block and a hook receiving swing arm, the hook head end located at the hook receiving position is hung on the receiving block, and the receiving block swings to the hook transfer position under the swing action of the hook receiving swing arm.

[0013] The technical solution is further configured such that the hook transfer assembly includes a hook transfer gripper and a hook transfer swing arm. The hook transfer gripper grips the head end of the hook located at the hook transfer position and swings to the hook loading position under the swing action of the hook transfer swing arm.

[0014] The technical solution is further configured such that the hook body flipping assembly includes a flipping block and a flipping swing arm, and the flipping block is provided with a receiving groove for accommodating the hook body rod and its tail end; The flipping arm drives the flipping block to swing, applying a flipping force to the hook body rod and its tail end, causing the hook head to slide into the hook hole on the plum blossom plate and the hook tail to be embedded in the mounting groove.

[0015] The beneficial effects of this invention are: 1. The alternating action of the limit column ensures that only one spool is allowed to enter the spool feeding position at any given time, thus avoiding the problem of multiple spools jamming, misalignment, or even damage to the workpiece caused by squeezing at the end of the spool feeding assembly. This greatly improves the continuity and stability of the equipment operation.

[0016] 2. Through the coordinated operation of the plum blossom feeding assembly, plum blossom transfer assembly, rotary table, hook feeding assembly, hook transfer assembly, and hook flipping assembly, the entire process of plum blossom feeding and transfer, hook feeding and transfer, and hook and plum blossom assembly is fully automated. The transfer paths and positions between each component are relatively fixed, thereby ensuring the consistency and reliability of hook and plum blossom assembly and reducing the defect rate.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0019] According to an embodiment of the present invention, a hook body and plum blossom-shaped assembly system is provided. Please refer to [link / reference]. Figures 1 to 2 ,as well as Figure 18The system is installed on the workbench 100 and has a compact overall layout. It achieves automated feeding, transfer, and precise assembly of the plum blossom pieces 900 and the hook body 110 through mechanical and electrical control. The core of the system includes the plum blossom piece feeding component 200, the plum blossom piece limiting component 120, the rotary table 400, the plum blossom piece transfer component 300, the hook body feeding component 500, the hook body transfer component 600, and the hook body flipping component 800. The components work together to solve the problems of plum blossom piece 900 stacking and low assembly accuracy of plum blossom pieces 900 and hook body 110 in the existing technology.

[0020] For the hook and plum blossom assembly system in this embodiment, please refer to [link / reference]. Figure 1 , Figure 2 as well as Figures 11 to 14 The plum blossom chip feeding assembly 200 is used to convey the plum blossom chips 900 arranged in sequence. It is inclined and relies on its own weight to slide the plum blossom chips 900. The first end (high end) of the plum blossom chip feeding assembly 200 is connected to the plum blossom chip vibrating screen. The plum blossom chip vibrating screen is responsible for orienting, sorting and outputting the disordered plum blossom chips 900. The plum blossom chips 900, after preliminary sorting, enter the plum blossom chip feeding assembly 200 smoothly and continuously.

[0021] Optionally, the plum blossom chip feeding assembly 200 includes a feeding housing 210. Inside the feeding housing 210, a plum blossom chip feeding channel is formed by a support rod assembly 230 and a pressure rod assembly 240 spaced vertically. Specifically, the support rod assembly 230 consists of two parallel and spaced-apart support rods, and the pressure rod assembly 240 consists of two parallel and spaced-apart pressure rods. The protrusion on the back of the plum blossom chip 900 is accommodated between the two support rods. The support rod assembly 230 supports the plum blossom chip 900, while the pressure rod assembly 240 restricts the movement of the plum blossom chip 900 from above, ensuring its single-row sliding.

[0022] Optionally, the lower end of the plum blossom sheet feeding assembly 200 serves as the end point, where a support rod assembly 230 extends to the outside of the feeding housing 210 and connects with the plum blossom sheet baffle plate 220 to form a plum blossom sheet feeding position. The plum blossom sheet baffle plate 220 is used to prevent the plum blossom sheet 900 from slipping and cooperates with the plum blossom sheet limiting assembly 120 for positioning.

[0023] For the hook and plum blossom assembly system in this embodiment, please refer to [link / reference]. Figure 1 , Figure 2 as well as Figures 11 to 14The plum blossom-shaped feeder component 120 is located at the end of the plum blossom-shaped feeder component 200, and includes a limiting mounting base 121, a first limiting post 122, and a second limiting post 123. The two limiting posts are driven by cylinders and can be raised and lowered independently. During operation, when the first limiting post 122 descends, it blocks the subsequent plum blossom-shaped feeder 900 from advancing, while the second limiting post 123 rises, allowing the last plum blossom-shaped feeder 900 to slide down to the feeder loading position. Subsequently, the first limiting post 122 rises and the second limiting post 123 descends, completing one isolation release. This alternating raising and lowering mechanism enables the sequential supply of the plum blossom-shaped feeder 900, avoiding accumulation caused by continuous pushing.

[0024] For the hook and plum blossom assembly system in this embodiment, please refer to [link / reference]. Figure 1 , Figure 2 as well as Figures 11 to 16 The plum blossom piece transfer assembly 300 is responsible for transferring the plum blossom pieces 900 on the plum blossom piece loading position to the rotary table 400.

[0025] Optionally, the plum blossom piece transfer assembly 300 includes a first transfer column 310, a first fixed base 320, a plum blossom piece transfer gripper 330, a plum blossom piece transfer gripper drive 340, a plum blossom piece transfer swing arm 350, a first arc-shaped slide rail 360, a connecting shaft 370, a linear guide rail 380, a slider 390, a plum blossom piece transfer swing arm drive 311, and a slider mounting base 312. The first fixed base 320 is mounted on the worktable 100 via the first transfer column 310. One end of the plum blossom piece transfer swing arm 350 is rotatably connected to the first fixed base 320, and the other end is connected to the transfer gripper 330 via the connecting shaft 370. The plum blossom piece transfer gripper drive 340 (such as a cylinder) controls the opening and closing of the plum blossom piece transfer gripper 330 to grip or release the plum blossom pieces 900.

[0026] Optionally, the first fixed base 320 is provided with a first arc-shaped slide rail 360, and the end of the plum blossom-shaped transfer arm 350 is provided with an oblong hole. The connecting shaft 370 passes through the oblong hole and the first arc-shaped slide rail 360 to form a sliding pair. At the same time, the plum blossom-shaped transfer gripper 330 is provided with a linear guide rail 380, and the slider 390 is rotatably connected to the first fixed base 320 through the slider mounting base 312, and the slider 390 slides in engagement with the linear guide rail 380.

[0027] Understandably, since the swing radius of the swaying arm 350 may differ from the radius of curvature of the first arc-shaped slide rail 360, the connecting shaft 370 will also slide relatively linearly within the oblong hole while sliding along the first arc-shaped slide rail 360. The oblong hole provides the necessary floating compensation space for this. When the swaying arm drive 311 drives the swaying arm 350, the swaying arm 350 reciprocates in an arc around its hinge point with the first fixed seat 320. When the swaying arm 350 swings, it pushes the connecting shaft 370 to move along the first arc-shaped slide rail 360 (i.e., the swaying arm 350 rotates along the first arc-shaped slide rail 360), causing the swaying jaw 330 to move in space. With the cooperation of the linear guide rail 380 and the slider 390, the swivel transfer gripper 330 swings between the swivel plate material position and the rotary disk 400. During this process, the swivel transfer gripper 330 always maintains a perpendicular posture to the swivel plate 900, achieving precise picking and placing.

[0028] After the 900 piece of metal is released to the 900 piece loading position, the 900 piece transfer gripper 330, driven by the 900 piece transfer arm 350, swings to the 900 piece loading position and grips it. The 900 piece transfer arm 350 then swings in the opposite direction, transferring the 900 piece of metal to the bearing groove 410 of the rotary disk 400. During the transfer process, due to the constraints of the linear guide rail 380 and the slider 390, the 900 piece of metal transfer gripper 330 always maintains a perpendicular posture to the 900 piece of metal, ensuring precise placement.

[0029] For the hook and plum blossom assembly system in this embodiment, please refer to [link / reference]. Figures 1 to 17 The rotating disk 400 is driven to rotate by a motor. Evenly spaced bearing grooves 410 are provided on its circumference, their shape matching the protrusions on the back of the plum blossom piece 900, ensuring the stability of the plum blossom piece 900 after insertion. The rotating disk 400 also has clearance grooves 420 on its edge, providing space for subsequent hook assembly. Simultaneously, the rotating disk 400 is equipped with a plum blossom piece pressing block 430, which can move vertically. During the assembly of the plum blossom piece 900 with the hook body 110, the plum blossom piece pressing block 430 descends and applies pressure to the plum blossom piece 900, preventing it from overturning.

[0030] For the hook and plum blossom assembly system in this embodiment, please refer to [link / reference]. Figures 1 to 10 The hook feeding assembly 500 is used to transport the sequentially arranged hooks 110 to the hook transfer position.

[0031] Optionally, the hook feeding assembly 500 includes a hook conveying track 510, a vibrator 511, a track cover plate 512, a hook baffle plate 513, a lifting plate assembly (a first lifting plate 514 and a second lifting plate 515), and a hook receiving unit 520. The hook conveying track 510 is connected to the hook vibrating screen, and a track cover plate 512 can be added to the hook conveying track 510. The two are arranged at intervals to form a hook conveying channel. The hook 110 is hung on the track with its hook head end 111 and slides orderly under the action of the vibrator 511.

[0032] Optionally, a material blocking and releasing mechanism is provided at the end of the hook conveying track 510: the hook blocking plate 513 can swing to open and close the connecting channel between the hook conveying track 510 and the inclined track 530, and the lifting plate assembly is driven to lift by the lifting plate drive component 516.

[0033] Initially, the top of the first lifting plate 514 is above the bearing surface of the hook conveying track 510, with a gap between them for the hook head 111 to pass through. The top of the second lifting plate 515 is flush with the bearing surface of the hook conveying track 510, allowing the last hook 110 in a single row to move smoothly from the hook conveying track 510 to above the second lifting plate 515 without obstruction. At this time, the hook is located between the second lifting plate 515 and the first lifting plate 514. After the lifting plate drive 516 drives the second lifting plate 515 and the first lifting plate 514 to descend synchronously, the descent of the second lifting plate 515 directly drives the hook 110 currently waiting to be released, which is supported above it, to descend synchronously. The hook 110 slides into the inclined track 530 under the action of gravity, completing one release. During the synchronous descent of the first lifting plate 514, its top moves from the initial "high position" to a position that contacts or is flush with the bearing surface of the hook conveying track 510. This change in position instantly eliminated the previously existing gap. As a result, the second hook, which was blocked by the first lifting plate 514, lost its path of advancement and was effectively stopped in place, thus achieving precise isolation of subsequent materials.

[0034] Optionally, the hook body stop plate 513 extends to the end of the hook body conveying track 510. The hook body stop plate 513 is connected to one end of the connecting plate 518. The middle part of the connecting plate 518 is connected to the track cover plate 512 via a rotating shaft. The other end of the connecting plate 518 is connected to the lifting plate drive component 516 via a stop connecting arm 517. Therefore, the hook body stop plate 513, the connecting plate 518, and the stop connecting arm 517 constitute a lever mechanism.

[0035] Understandably, when the lifting plate drive 516 is in its initial position, the hook stop plate 513 swings to a vertical position via the lever mechanism, closing the connection channel between the hook conveying track 510 and the inclined track 530, preventing the hook 110 from passing. Simultaneously, the first lifting plate 514 and the second lifting plate 515 are in a high position, ready to receive the hook. When a hook needs to be released, the lifting plate drive 516 actuates, causing the first lifting plate 514 and the second lifting plate 515 to descend synchronously, moving the carried hook downwards. Simultaneously, the right end of the connecting plate 518 is pushed downwards via the stop connecting arm 517. According to the lever principle, the left end of the connecting plate 518 (the end where the hook stop plate 513 is installed) swings upwards, thereby lifting the hook stop plate 513 and opening the connection channel. At this time, the descending hook can slide into the inclined track 530 through the channel. After the material is discharged, the lifting plate drive component 516 resets, the lifting plate assembly rises, and at the same time the hook body baffle plate 513 swings downward under the drive of the lever mechanism, resetting to the closed channel state, ready for the next cycle.

[0036] By adopting the above technical solution, when the hook baffle 513 swings to the point where the connecting channel is open, the lifting plate assembly descends, allowing the last hook 110 in a single row to enter the connecting channel under gravity and slide onto the inclined track 530. Through the cooperation of the hook baffle 513 and the lifting plate assembly, intermittent, single-piece feeding of the hook 110 is achieved, ensuring accurate material receiving at subsequent workstations.

[0037] Optionally, the hook receiving unit 520 is located at the end of the inclined track 530, with the lower end of the inclined track 530 being the hook receiving position. The hook receiving unit 520 includes a receiving block 522 and a hook receiving swing arm 521. The receiving block 522 supports the hook head 111. The hook receiving swing arm 521 is mounted on the worktable 100 via a receiving mounting seat and is driven by a drive component (not shown in the figure, such as a rotary cylinder) to reciprocate. When the hook 110 reaches the receiving block 522, the hook receiving swing arm 521 immediately swings upward, precisely transferring the hook 110 from the hook receiving position to the predetermined hook transfer position.

[0038] Optionally, to fix the movement path of the hook 110 from the hook receiving position to the predetermined hook transfer position, an arc-shaped guide plate 523 is fixed on the receiving mounting base, and the receiving block 522 is slidably sleeved on the periphery of the guide plate 523. The two ends of the guide plate 523 correspond to the hook receiving position and the hook transfer position, respectively. By forcibly constraining the movement path, radial swaying or trajectory deviation that may occur during the swinging of the receiving block 522 is completely avoided. This allows the hook 110 to be accurately and reliably transported to the predetermined hook transfer position, ensuring that it is always within the gripping range of the hook transfer assembly 600.

[0039] For the hook and plum blossom assembly system in this embodiment, please refer to [link / reference]. Figures 1 to 10 The hook transfer assembly 600 transfers the hook 110 from the hook transfer position to the scallop plate 900 on the rotating disk 400.

[0040] Optionally, the hook transfer assembly 600 includes a second transfer column 610, a second fixed base 620, a hook transfer swing arm 630, a transfer connecting arm 640, a hook transfer drive component 650, and a hook transfer gripper 660. One end of the hook transfer swing arm 630 is mounted via the second fixed base 620 and is driven to swing by the hook transfer drive component 650. The second fixed base 620 is mounted on the second transfer column 610. The other end of the hook transfer swing arm 630 is connected to the hook transfer gripper 660 via the transfer connecting arm 640. The hook transfer gripper 660 can be opened and closed by a cylinder to grip the hook head end 111.

[0041] Optionally, a second arc-shaped slide rail 621 is provided on the second fixed base 620 to ensure the smooth movement trajectory of the hook transfer arm 630. The two ends of the second arc-shaped slide rail 621 correspond to the hook transfer position and the hook loading position, respectively.

[0042] After the hook body transfer gripper 660 grips the hook body head end 111, the hook body transfer swing arm 630 swings along the second arc-shaped slide rail 621 to accurately transfer the hook body 110 to the hook body loading position (i.e. above the plum blossom piece 900 of the rotary disk 400).

[0043] For the hook and plum blossom assembly system in this embodiment, please refer to [link / reference]. Figures 1 to 10 The hook body flipping assembly 800 is used to complete the final assembly and includes a flipping swing arm 810 and a flipping block 820. The flipping swing arm 810 is rotatably mounted on the flipping mounting base and is driven by a drive (not shown in the figure, such as a rotary cylinder) to reciprocate.

[0044] Optionally, the tilting block 820 has a receiving groove 821 whose shape matches the hook rod 112 and hook tail 113. When the hook 110 is fed to the hook loading position (at this time, the hook head 111 is suspended and aligned with the hook hole 920 on the plum blossom plate 900), the hook rod 112 and tail 113 fall into the receiving groove 821. Subsequently, the tilting arm 810 swings upward under the action of the drive component, driving the tilting block 820 to apply an upward tilting force to the hook rod 112 and tail 113, forcing the hook 110 to tilt with its head 111 as the fulcrum, so that the hook head 111 slides smoothly downward into the hook hole 920, and finally the hook tail 113 is accurately embedded in the mounting groove 910, completing the automated hooking operation. At the same time, the clearance groove 420 provides clearance space for unloading and avoids interference.

[0045] Optionally, a rejection assembly 700 is detachably installed on the worktable 100 to reject defective pieces 900 that are not fitted with hooks 110. The rejection assembly 700 includes a sensor, an air nozzle, and a collection box. The sensor is located below the rotating disk 400 and corresponds to the clearance groove 420. The air nozzle is located above the rotating disk 400 and corresponds to the carrying groove 410 and the collection box. When the sensor does not detect a hook 110, the air nozzle actuates to blow the pieces 900 without hooks 110 into the collection box.

[0046] The workflow of this invention is as follows: 1. The plum blossom sheet feeding assembly 200 conveys the plum blossom sheet 900 to its end. The plum blossom sheet limiting assembly 120 releases the plum blossom sheet 900 to the plum blossom sheet loading position one by one by alternating the lifting and lowering of the limiting column.

[0047] 2. The plum blossom piece transfer assembly 300 picks up the plum blossom piece 900 and transfers it to the bearing groove 410 of the rotary disk 400. The rotary disk 400 then points to the next station.

[0048] 3. The hook feeding assembly 500 releases the hook 110 piece by piece to the hook receiving position through the vibration conveying and material blocking and releasing mechanism, and the hook receiving unit 520 transfers it to the hook transfer position.
