Description

Technical Field

[0001] This invention relates to the field of injection molding production equipment technology, specifically to a steel sleeve mounting device for injection molding parts. Background Technology

[0002] In the injection molding process, steel sleeves are typically installed inside the threaded holes of the molded parts to extend their service life. Currently, this installation mainly relies on manual labor and simple pressing equipment: the operator first manually places the steel sleeves one by one into the predetermined holes of the injection molded parts, then transfers the workpieces with the steel sleeves installed to the pressing equipment for pressing in. After pressing, the finished product is manually inspected to confirm that the steel sleeves are pressed in to the required depth, sag, and other specifications. The entire process involves multiple steps, including steel sleeve handling, pressing, and inspection. This not only requires multiple transfers between different workstations, resulting in low production efficiency, but also heavily relies on manual operation, leading to high labor intensity and insufficient stability for workers. Summary of the Invention

The rotating table has an installation station for the injection molded part. The clamping mechanism includes a stand, a slider, a sliding drive component, a clamp, a clamping drive component, and a steel sleeve transport groove. The stand is fixed to the base, the slider is slidably mounted on the stand in a direction toward or away from the installation station, and the sliding drive component is mounted on the stand. The device is used to drive the slider to slide on the stand. The clamp and the clamping drive are both installed on the slider. The clamping drive is used to drive the clamp to perform clamping or releasing actions. The steel sleeve transport groove is located below the slider. The outlet end of the steel sleeve transport groove corresponds to the position of the clamp. The inlet of the steel sleeve transport groove is connected to the vibrating feeding mechanism. The vibrating feeding mechanism is used to transport the steel sleeves into the steel sleeve transport groove in an orderly manner. The clamp can clamp the steel sleeve in the transport groove under the drive of the clamping drive and place the steel sleeve in the predetermined hole position of the injection molded part under the drive of the sliding drive. By rotating the turntable, the injection molded part with the steel sleeve can be transported to the pressing mechanism, the detection mechanism and the dispensing mechanism for corresponding processing in sequence.

[0005] Further optimization of the steel sleeve mounting device for injection molded parts: The clamp includes an outer cylinder, a core cylinder, an inner core, and an elastic hoop. The outer cylinder includes a first half-cylinder and a second half-cylinder that are aligned axially. The elastic hoop is sleeved on the outside of the outer cylinder and is used to maintain the alignment of the first half-cylinder and the second half-cylinder. The inner walls of the first half-cylinder and the second half-cylinder together form an inner cavity that penetrates the outer cylinder axially. The core cylinder is located in the inner cavity. Both the first half-cylinder and the second half-cylinder have slotted holes. The major diameter of the slotted holes is along the axial direction of the outer cylinder. A limiting shaft connected to the core cylinder is provided in the slotted holes. The diameter of the limiting shaft is smaller than the minor diameter of the slotted holes. A through hole coaxial with the inner cavity is provided in the core cylinder. The inner core is slidably located in the through hole. A clamping drive is used to drive the core cylinder to move axially along the outer cylinder, which can drive the outer cylinder to move down and clamp the steel sleeve at the bottom of the inner cavity. The clamping drive is also used to drive the inner core to move axially along the outer cylinder, which can push the steel sleeve out of the inner cavity.

[0006] Further optimization of the steel sleeve mounting device for injection molded parts: The clamping drive includes a first clamping drive and a second clamping drive. The first clamping drive is used to drive the core cylinder to move axially along the outer cylinder, and the second clamping drive is used to drive the inner core to move axially along the outer cylinder.

[0007] Further optimization of the steel sleeve mounting device for injection molded parts: A first clamping drive is located above the slider, and a first moving plate is provided at the output end of the first clamping drive. At least one clamp is provided at the bottom of the first moving plate, and the core cylinder of the clamp is connected to the first moving plate. A second clamping drive is located at the bottom of the slider, and a second moving plate is provided at the output end of the second clamping drive. The second moving plate is connected to the inner core of the clamp located at the bottom of the first moving plate.

[0008] Further optimization of the steel sleeve mounting device for injection molded parts: the number of fixtures and the installation position are matched with the number and position of the predetermined holes in the injection molded parts, and the number of steel sleeve transport grooves is matched with the number of fixtures.

[0009] Further optimization of the steel sleeve mounting device for injection molded parts: A top plate and a lifting drive are provided below the steel sleeve conveying channel. The lifting drive is mounted on a vertical frame, and its output end is connected to the top plate. The lifting drive is used to drive the top plate to move toward or away from the steel sleeve conveying channel. The top plate is provided with a protrusion, which corresponds to the position of the outlet end of the steel sleeve conveying channel. By driving the top plate toward the steel sleeve conveying channel through the lifting drive, the protrusion can lift the steel sleeve located at the outlet end of the steel sleeve conveying channel to provide clamping space for the fixture.

[0010] Further optimization of the steel sleeve mounting device for injection molded parts: The pressing mechanism includes a pressing frame, a pressing drive, a pressure plate and at least one column. The pressing frame is fixed on the base, the pressing drive is located on the pressing frame, the pressure plate is located at the output end of the pressing drive, and the column is located at the bottom of the pressure plate. The position and number of the column correspond to the predetermined holes on the injection molded part.

[0011] Further optimization of the steel sleeve mounting device for injection molded parts: The inspection mechanism includes an inspection frame, a CCD camera and a lighting lamp. The inspection frame is fixed on the base, and the CCD camera and the lighting lamp are mounted on the inspection frame.

[0012] Further optimization of the steel sleeve mounting device for injection molded parts: The dispensing mechanism includes a first robotic arm, a second robotic arm, a material conveying track, and a collection tank. Both the first and second robotic arms are mounted on a base. The first robotic arm is used to pick up qualified injection molded parts and place them onto the material conveying track, which is used to transport qualified products to a predetermined station. The second robotic arm is used to pick up unqualified injection molded parts and place them onto the collection tank, which is used to guide unqualified products to a predetermined station.

[0013] Further optimization of the steel sleeve mounting device for injection molded parts: Multiple mounting stations for injection molded parts are evenly arranged along the circumference of the rotating table.

[0014] Beneficial effects: By arranging the clamping mechanism, pressing mechanism, detection mechanism and dispensing mechanism sequentially on the base along the rotation direction of the rotating table, and having the rotating table carry the injection molded parts to each processing station in sequence, the present invention realizes the continuous operation of automatic feeding, clamping, placement, pressing, quality inspection and sorting of qualified products of steel sleeves. This reduces the workpiece transfer process and human intervention, significantly improves production efficiency, and solves the problems of low efficiency and high labor intensity of existing steel sleeve installation operations.

[0015] This invention, by setting up an outer cylinder, a core cylinder, an inner core, an elastic hoop, a strip hole, a limiting shaft, a first clamping drive, and a second clamping drive, ensures that the core cylinder can drive the outer cylinder to move as a whole to complete the steel sleeve clamping action through the cooperation of the strip hole and the limiting shaft. It also provides necessary clearance space for the limiting shaft when the bottom end of the outer cylinder opens, avoiding motion interference. At the same time, the movement of the outer cylinder and the ejection of the inner core are driven by the first clamping drive and the second clamping drive, respectively, realizing the mechanization of clamping and ejection actions, improving the efficiency of steel sleeve picking and placing, and further improving the efficiency of steel sleeve installation.

[0018] Example 1

[0019] like Figure 1 and combined Figure 2 As shown, a steel sleeve mounting device for injection molded parts includes a base 11, a rotating table 12, a clamping mechanism 7, a pressing mechanism 8, a detection mechanism 9, and a dispensing mechanism 10.

[0020] The base 11 serves as the supporting foundation for the entire device, and is fixed to the working ground or frame. In this embodiment, it is fixed to the frame, providing a stable mounting surface and support for the rotating platform 12 and various mechanisms.

[0021] The rotary table 12 is rotatably mounted on the base 11 via a slewing bearing and a servo motor. Multiple mounting stations 14 for injection molded parts 13 are evenly arranged circumferentially on the surface of the rotary table 12. Each mounting station 14 is a mounting groove adapted to the shape of the injection molded part 13, enabling accurate positioning and reliable fixing of the injection molded part 13. In this embodiment, there are six mounting stations 14, corresponding to a manual injection molded part placement station, a clamping station, a pressing station, an inspection station, a qualified product gripping station, and a defective product gripping station. This allows each station to perform its respective operation simultaneously after the rotary table 12 rotates one station, improving production efficiency.

[0022] like Figure 3As shown, the clamping mechanism 7 is set at the clamping station and is used to clamp the steel sleeve from the feeding position to the predetermined hole position of the injection molded part. The clamping mechanism 7 includes a stand 3, a slider 4, a sliding drive 6, a clamp 17, a clamping drive 5, and a steel sleeve transport groove 2. The stand 3 is fixed on the base 11, and the slider 4 is slidably mounted on the stand 3 along a linear guide rail in a direction toward or away from the installation station 14.

[0023] The sliding drive component 6 is a cylinder, fixed on the stand 3, and its output end is connected to the slider 4 to drive the slider 4 to reciprocate. The clamp 17 and the clamping drive component 5 are both mounted on the slider 4 and move together with the slider 4.

[0024] The steel sleeve transport trough 2 is fixed on the upright frame 3 below the slider 4. Its inlet is connected to the vibrating feeding mechanism 1. The vibrating feeding mechanism 1 is a vibrating plate that can arrange the scattered steel sleeves in an orderly manner and transport them to the outlet end of the steel sleeve transport trough 2. The outlet end is directly opposite the position of the clamp 17 in the material picking state.

[0025] like Figure 4 and combined Figure 5 As shown, the clamp 17 includes an outer cylinder 27, a core cylinder 24, an inner core 19, and an elastic clamp 28. The outer cylinder 27 includes a first half-cylinder 2701 and a second half-cylinder 2702 that are axially aligned. The elastic clamp 28 is a spring coil fitted around the outside of the outer cylinder 27 and provides radial constriction force, keeping the first half-cylinder 2701 and the second half-cylinder 2702 in an aligned state. The inner walls of the first half-cylinder 2701 and the second half-cylinder 2702 together form an inner cavity 26 that extends axially through the outer cylinder 27. The inner wall of the lower end of the inner cavity 26 has a tapered constriction structure. During operation, the outer cylinder 27 moves downward to compress the steel sleeve, which can open the first half-cylinder 2701 and the second half-cylinder 2702 to enter the inner cavity 26. Under the action of the elastic clamp 28, the first half-cylinder 2701 and the second half-cylinder 2702 can stably clamp the steel sleeve.

[0026] The core cylinder 24 is housed within the inner cavity 26. Both the first half-cylinder 2701 and the second half-cylinder 2702 have slotted holes 30, with the major axis of the slotted holes 30 aligned axially with the outer cylinder 27. A limiting shaft 29, connected to the core cylinder 24, is located within the slotted hole 30. The diameter of the limiting shaft 29 is smaller than the minor axis of the slotted hole 30. The limiting shaft 29 is a bolt, and a threaded hole is correspondingly located on the core cylinder 24. The connection between the limiting shaft 29 and the core cylinder 24 is achieved through the engagement of the bolt and the threaded hole. The engagement between the slotted hole 30 and the limiting shaft 29 enables the core cylinder 24 to move, thus moving the outer cylinder 27. The slotted holes provide sufficient space for the limiting shaft 29 to move when the bottom of the outer cylinder 27 is open, preventing motion interference.

[0027] The core cylinder 24 has a through hole 25 coaxial with the inner cavity 26 along its center. The inner core 19 is slidably disposed within the through hole 25. The clamping drive 5 includes a first clamping drive 22 and a second clamping drive 21. The first clamping drive 22 drives the core cylinder 24 to move axially along the outer cylinder 27, and the second clamping drive 21 drives the inner core 19 to move axially along the outer cylinder 27. When it is necessary to grasp the steel sleeve, the first clamping drive 22 drives the core cylinder 24 to move, which in turn drives the outer cylinder 27 to move, allowing the outer cylinder 27 to clamp the steel sleeve. When it is necessary to place the steel sleeve, the second clamping drive 21 drives the inner core 19 to move, which pushes the steel sleeve out of the inner cavity 26.

[0028] The first clamping drive member 22 is located above the slider 4. The output end of the first clamping drive member 22 is provided with a first moving plate 18. At least one clamp 17 is located at the bottom of the first moving plate 18. The core cylinder 24 of the clamp 17 is connected to the first moving plate 18. The second clamping drive member 21 is located at the bottom of the slider 4. The output end of the second clamping drive member 21 is provided with a second moving plate 20. The second moving plate 20 is connected to the inner core 19 of the clamp 17 located at the bottom of the first moving plate 18. By driving the first moving plate 18 to move through the first clamping drive member 22, the core cylinders 24 of multiple clamps 17 can be driven to move simultaneously, thereby simultaneously driving multiple outer cylinders 27 to move, enabling the simultaneous gripping of multiple steel sleeves. By driving the second moving plate 20 through the second clamping drive member 21, the inner cores 19 of multiple clamps 17 can be driven to move synchronously, thereby simultaneously ejecting the steel sleeves from multiple clamps 17. The number and installation position of the clamps 17 are matched with the number and position of the predetermined holes of the injection molded part, which can simultaneously perform steel sleeve placement operations on multiple predetermined holes of a single injection molded part, thereby improving the working efficiency of the device.

[0029] In this embodiment, four clamps 17 are provided, and the first clamping drive 22 and the second clamping drive 21 are both cylinders.

[0030] like Figure 3 As shown, a top plate 15 and a lifting drive 16 are provided below the steel sleeve conveying trough. In this embodiment, the lifting drive 16 is a cylinder. The lifting drive 16 is mounted on the upright 3, and its output end is connected to the top plate 15. The lifting drive 16 is used to drive the top plate 15 to move toward or away from the steel sleeve conveying trough.

[0031] The top plate 15 is provided with a protrusion 23, which corresponds to the outlet position of the steel sleeve conveying groove. When the lifting drive 16 drives the top plate 15 to move toward the steel sleeve conveying groove, the protrusion 23 lifts the steel sleeve located at the outlet end of the steel sleeve conveying groove, so that the cylindrical section of the steel sleeve is exposed outside the conveying groove, providing unobstructed clamping space for the outer cylinder 27 of the clamp 17.

[0032] In this embodiment, the number of steel sleeve transport grooves 2 matches the number of clamps 17, and the outlet end of the steel sleeve transport groove 2 corresponds to the position of the clamp 17. Therefore, this embodiment also has 4 steel sleeve transport grooves 2. The position and number of protrusions 23 on the top plate 15 also match the number and position of the steel sleeve transport grooves 2. Therefore, the top plate 15 has 4 protrusions 23.

[0033] like Figure 1 As shown, the pressing mechanism 8 is set up corresponding to the pressing station, including a pressing frame 801, a pressing drive 802, a pressure plate 803, and at least one column 804. The pressing frame 801 is fixed on the base 11, and the pressing drive 802 is set on the pressing frame 801. In this embodiment, the pressing drive 802 is also a cylinder. The pressure plate 803 is set at the output end of the pressing drive 802, and the column 804 is set at the bottom of the pressure plate 803. The position and number of the columns 804 correspond to the predetermined holes on the injection molded part. In this embodiment, there are 4 columns 804. During pressing, the pressing drive 802 drives the pressure plate 803 and the columns 804 to press down. The lower end face of the column 804 abuts against the upper end face of the steel sleeve, pressing it into the hole of the injection molded part to the set depth.

[0034] The inspection mechanism 9 is set up corresponding to the inspection station, including an inspection frame 901, a CCD camera 902, and a lighting lamp 903. The inspection frame 901 is fixed on the base 11, and the CCD camera 902 and the lighting lamp 903 are mounted on the inspection frame 901. The inspection frame 901 is fixed on the base 11, and the CCD camera 902 and the ring lighting lamp 903 are mounted on the top of the inspection frame 901, with the lens pointing vertically downwards towards the inspection station on the rotating table 12. When the injection-molded part is rotated to this station after pressing, the CCD camera 902 captures an image of the pressing state of the steel sleeve, providing a basis for judging whether the pressing depth and perpendicularity of the steel sleeve are qualified.

[0035] The dispensing mechanism 10 includes a first robotic arm 1001 and a second robotic arm 1002 respectively positioned at a qualified product gripping station and a non-qualified product gripping station, as well as a conveyor rail 1003 cooperating with the first robotic arm 1001 and a collection trough 1004 cooperating with the second robotic arm 1002. Both the first robotic arm 1001 and the second robotic arm 1002 are mounted on a base 11. The first robotic arm 1001 grips qualified injection molded parts onto the conveyor rail 1003, which is a belt conveyor line used to transport qualified products to a predetermined station. The second robotic arm 1002 grips non-qualified injection molded parts onto the collection trough 1004, which is an inclined chute with its lower end leading to a non-qualified product collection box, used to guide non-qualified products to the predetermined station.

[0036] The manual loading station is located before the clamping station. There is no automatic mechanism here. The operator manually or with the help of auxiliary tools places the injection molded part to be installed with the steel sleeve into the empty installation station 14 on the rotating table 12.

[0037] The method of using the steel sleeve installation device for injection molded parts according to the present invention is as follows: Initially, the operator places the first injection molded part into the empty installation station 14 at the manual loading station. The rotating table 12 rotates one station step by step, sending the injection molded part to the clamping station. At the same time, the vibrating feeding mechanism 1 continuously and orderly conveys the steel sleeve to the outlet end of the steel sleeve transport trough 2. The lifting drive 16 drives the top plate 15 to rise, and the protrusion 23 lifts the foremost steel sleeve. In the clamping mechanism 7, the sliding drive 6 pushes the slider 4 to move the clamp 17 to the material picking position. The first clamping drive 22 drives the core cylinder 24 to move downward. The core cylinder 24 drives the outer cylinder 27 to move downward through the limiting shaft 29. The outer cylinder 27 clamps the inner cavity 26 and covers the steel sleeve with the help of the elastic hoop 28. The lifting drive 16 retracts, and the sliding drive 6 drives the slider 4 to move above the installation station 14. The second clamping drive 21 drives the inner core 19 to move downward, pushing the steel sleeve out of the inner cavity 26 of the outer cylinder 27 and pre-inserting it into the injection molded part's hole. The slider 4 resets, and the rotary table 12 steps forward again, moving the injection molded part to the pressing station. Subsequent injection molded parts enter the clamping station sequentially from the manual loading station. At the pressing station, the pressing drive 802 drives the pressure plate 803 and the column 804 to press down, pressing the steel sleeve to the set depth. After pressing is completed, the injection molded part enters the inspection station with the rotary table, where the lighting lamp 903 provides supplemental lighting, and the CCD camera 902 captures images. After inspection, the turntable moves to the qualified product grabbing station: if the injection molded part is qualified, the first robotic arm 1001 grabs it and places it on the conveying track 1003 for delivery, and the installation station 14 becomes empty; if it is unqualified, the first robotic arm 1001 does not move, the turntable moves to the unqualified product grabbing station, and the second robotic arm 1002 grabs the unqualified product and places it into the collection tank 1004. The empty installation station 14 continues to rotate with the turntable back to the manual loading station, where the operator can place a new injection molded part, and so on. In this process, the six installation stations 14 and the six operation stations simultaneously perform their respective functions in each cycle: the manual loading station places the injection molded part, the clamping station picks up and puts in the steel sleeve, the pressing station performs the pressing operation, the inspection station performs quality inspection, and the qualified product grabbing station and the unqualified product grabbing station alternately or simultaneously complete the sorting and output of qualified and unqualified products according to the inspection results, realizing parallel and continuous operation of the entire process.

[0038] Example 2

[0039] This embodiment is an optimization based on Embodiment 1.

[0040] In this embodiment, the rotating table 12 is equipped with 8 installation stations 14, including 3 manual loading stations, allowing operators to install multiple injection molded parts 13 at once. This reduces the frequency of manual loading, further alleviating labor intensity; at the same time, it provides ample loading windows for manual operation, allowing for easy loading and improving the smoothness of human-machine cooperation.
