Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and more specifically to an automatic granule inserting device. Background Technology

[0002] Plastic granule fittings are commonly used in the assembly of plastic parts, electronic components, and automotive interior products. The assembly method typically involves pressing the granule fitting into pre-drilled holes in the workpiece to form the basic structure for subsequent fastening, positioning, or connection. In mass production scenarios, the same workpiece often has multiple insertion holes, and the granule fittings need to be inserted one by one according to these holes.

[0003] Currently, this type of insertion process still largely relies on manual feeding and manual pressing. Operators need to repeatedly pick up materials, align holes, press in, and check, resulting in high labor intensity. The production cycle is significantly affected by the operator's skill level, easily leading to problems such as inconsistent insertion depth, hole misalignment, missed insertion, or incorrect insertion, making it difficult to maintain product consistency and yield. At the same time, manual methods are costly under the production requirements of multiple holes and high cycle times, and are not conducive to standardized management of the production process.

[0004] To address the aforementioned issues, some automated inserting equipment has attempted to incorporate vibratory feeder feeding and robotic arm pick-and-place structures. However, several shortcomings remain in practical applications: First, when the end posture of the feeding end is unstable or the transition structure is unreasonable, the granules are prone to accumulating, jamming, or flipping at the end, causing pick-up failure and machine downtime. Second, when the guiding and reference structures for the workpiece hole positioning are imperfect, the repeatability of feeding positioning is insufficient, and bias or incomplete insertion is likely to occur during insertion. Third, when the timing of pick-up and insertion actions is poorly matched with the feeding action, waiting and increased idle strokes are likely to occur, affecting overall production capacity. Fourth, when the equipment structure is not adaptable enough, changing workpieces or granule specifications requires a large range of adjustments, resulting in low maintenance and changeover efficiency.

[0005] Therefore, there is a need for an automatic granule inserting equipment with a reasonable structure, continuous and stable material supply, reliable feeding and positioning, and the ability to adapt to the requirements of continuous inserting production in multiple positions, so as to improve inserting efficiency and inserting consistency and reduce downtime risk. Utility Model Content

[0006] The purpose of this utility model is to overcome the problems of low feeding and positioning accuracy, low degree of automation and insufficient safety in the existing technology, and to provide an automatic granule accessory insertion device. Through multi-station arrangement and multi-set clamping, the profile is clamped, fed, punched and discharged sequentially along a fixed path.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic granule inserting device includes a frame, a track, a feeding mechanism, a conveying mechanism, and an inserting mechanism;

[0009] The track is mounted on the frame and serves as the guide rail for the feeding mechanism;

[0010] The feeding mechanism is installed on the track and moves along the track. A fixture is provided on the feeding mechanism. The fixture is used to carry and fix the workpiece to be inserted. The feeding mechanism drives the fixture and the workpiece to move so that the insertion holes of the workpiece arrive at the insertion station in sequence.

[0011] The feeding mechanism is installed on the frame. The feeding mechanism includes a vibratory feeder, a spiral feeding track, a straight vibrating channel, and a feeding transfer assembly. The vibratory feeder outputs the granular accessories in an orderly manner to the straight vibrating channel through the spiral feeding track. The discharge end of the straight vibrating channel forms a material pick-up position through the feeding transfer assembly.

[0012] The insertion mechanism includes a PPU robotic arm module and an insertion actuator disposed at the end of the PPU robotic arm module. The PPU robotic arm module is driven by a drive motor to reciprocate between the material picking position and the insertion station. The insertion actuator is used to press the granule accessory into the insertion hole of the workpiece.

[0013] Preferably, the track is a linear guide rail, and the feeding mechanism includes a slider seat that cooperates with the linear guide rail to realize the linear guided movement of the feeding mechanism along the track.

[0014] Preferably, the fixture is disposed on the slide of the feeding mechanism, and the fixture and the slide are detachably connected to each other to allow for the replacement of fixtures of different specifications.

[0015] Preferably, the feeding adapter is disposed at the discharge end of the direct vibrating material channel, and the feeding adapter has a guide groove for limiting the rubber granule accessories so that the rubber granule accessories maintain a consistent posture at the material picking position.

[0016] Preferably, the vibratory feeder is installed on the upper part of the frame, and the linear vibratory feed channel is disposed on the frame and connected to the discharge end of the vibratory feeder.

[0017] Preferably, the insert actuator includes a linear drive and a pin, wherein the pin is detachably connected to the output end of the linear drive to allow for the replacement of pins of different specifications.

[0018] Compared with existing technologies, this invention uses a dedicated guide rail as the motion reference for the feeding mechanism, ensuring that the workpiece carried by the fixture maintains a stable linear guidance and repeatable positioning relationship during movement. This facilitates the sequential arrival of each insertion hole at the insertion station, improving the repeatability of hole alignment and the consistency of insertion. The feeding end uses a vibratory feeder in conjunction with a spiral feeding track and a straight vibrating channel to form a continuous conveying link. A feeding transfer component at the end limits and maintains the posture of the granule parts, reducing posture fluctuations and jamming probability during end-of-line material handling, and improving material handling stability. The insertion end uses a motor-driven PPU module that reciprocates between the material handling position and the insertion station. Combined with the hole-by-hole displacement of the feeding mechanism, it achieves a cyclical coordination of feeding positioning, material handling, and insertion, which helps shorten the single-hole insertion cycle and improve the efficiency of multi-hole continuous insertion. The operation interface is centrally located, facilitating parameter setting, status observation, and maintenance, improving the overall ease of use and production organization efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figures 1 to 3 As shown, an automatic granule accessory inserting device in this embodiment includes a frame 1, a track 2, a vibratory feeder 3, a spiral feeding track 301, a feeding mechanism 4, a linear vibratory feed channel 5, a feeding transfer assembly 6, a fixture 601, a drive motor 7, a PPU robotic arm module 8, and a central control console 9.

[0027] The frame 1 is a profile frame structure used to support and install various functional components. The track 2 is fixedly installed on the frame 1, serving as a guide track for the feeding mechanism 4, providing linear guidance for the movement of the feeding mechanism 4 and providing a repeatable positioning reference. The feeding mechanism 4 is mounted on the track 2, preferably a linear module structure, with its slide moving along the track 2. A fixture 601 is installed on the slide, used to clamp and position the workpiece to be inserted, ensuring the workpiece remains stable during feeding movement and insertion under force. The fixture 601 and the slide of the feeding mechanism 4 are preferably detachably connected to facilitate the replacement of different specifications of fixture 601 to adapt to different workpiece models.

[0028] The feeding mechanism is mounted on the frame 1 and includes a vibratory feeder 3, a spiral feeding track 301, a straight vibrating feed channel 5, and a feeding transfer assembly 6. The vibratory feeder 3 is used to orient and continuously output the granules. Under vibration, the granules move upwards along the spiral feeding track 301 and enter the straight vibrating feed channel 5 from the discharge end of the vibratory feeder 3. The straight vibrating feed channel 5 is used to linearly transport the granules to the end in a single row. The feeding transfer assembly 6 is located at the discharge end of the straight vibrating feed channel 5. The feeding transfer assembly 6 has a guiding and limiting structure to constrain the posture of the granules reaching the end, ensuring that the granules remain stable and aligned at the picking position, thus facilitating subsequent picking and insertion.

[0029] The insertion mechanism includes a PPU robotic arm module 8 and a drive motor 7. The drive motor 7 is connected to the PPU robotic arm module 8 and is used to drive the PPU robotic arm module 8 to reciprocate and position itself between the material picking position and the insertion station. An insertion actuator is installed at the end of the PPU robotic arm module 8. The insertion actuator is preferably a linear cylinder structure, with a pin at its output end. The pin is used to support or position the granule component during material picking and to press the granule component into the workpiece hole during insertion. Preferably, the pin is detachably connected to the output end of the insertion actuator to facilitate the replacement of pins of different specifications.

[0030] This embodiment also includes a control system, which coordinates and controls the timing of feeding, material feeding, and insertion actions. The control system uses a central control console 9 as the human-machine interface, which is used for switching operating modes, setting the number of holes, setting cycle time parameters, displaying alarm information, and manual jogging operations. The control system internally includes a controller, a drive unit, and input / output interfaces. The controller is electrically or signal-connected to the feeding mechanism 4, the drive motor 7, and the PPU robotic arm module 8, and is used to output control commands for feeding movement and insertion reciprocating. Simultaneously, the controller is signal-connected to the vibratory feeder 3 and the direct-drive material channel 5, and is used to control the start and stop of material feeding and matching the feeding cycle time. The input / output interfaces are used to receive signals such as position detection, material shortage detection, emergency stop, and safety interlock, and stop feeding and insertion actions and material feeding when an emergency stop or interlock condition is triggered.

[0031] The working process of this embodiment is as follows: The operator clamps the workpiece to be inserted onto the fixture 601, selects the automatic operation mode and sets the number of holes and cycle parameters through the central control panel 9; the vibratory feeder 3 and the linear vibratory feed channel 5 operate, so that the granule accessories are transported to the picking position formed by the feeding transfer assembly 6 via the spiral feeding track 301 and the linear vibratory feed channel 5. Then the feeding mechanism 4 moves along the track 2, sending the first hole to be inserted into the workpiece to the insertion station; the PPU robotic arm module 8 moves to the picking position under the action of the drive motor 7 and completes the picking, then moves to the insertion station and performs the pressing insertion, completing one insertion. After one insertion is completed, the feeding mechanism 4 moves along the track 2 to the next hole, and the PPU robotic arm module 8 returns to the picking position to enter the next cycle, until the set number of holes is inserted. After the insertion is completed, the feeding mechanism 4 returns to the picking and unloading position, prompting the operator to remove the inserted workpiece and clamp the next workpiece, realizing continuous production.

[0032] In the above embodiments, the specific electrical component models, communication methods, and parameter setting interface forms of the control system can be adjusted according to the on-site configuration. As long as the linkage control and safety interlock of the feeding mechanism 4, the material supply mechanism, and the insertion mechanism can be achieved, the operating effect of this embodiment can be achieved.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
