Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing and processing technology, specifically to an automatic bushing embedding device and an automatic bushing embedding system. Background Technology

[0002] Currently, bushing installation in automotive parts manufacturing primarily relies on manual operation or mechanical grippers. In manual operation, workers must individually pick up, place, position, and pre-fix bushings, which not only carries a high risk of missed installations and potential mold damage, but also poses a risk of burns when workers directly contact the high-temperature molds during bushing installation. While mechanical grippers partially replace manual operation, they still require manual pre-installation of the bushings on the gripper fingers, hindering the improvement of production line automation and limiting overall operational efficiency.

[0016] Optionally, the bushing channel is arranged inclined downward along the first radial direction.

[0017] Optionally, multiple bushing flow channels and multiple bushing access channels are provided, with each bushing flow channel corresponding to one another and distributed vertically.

[0018] Optionally, the bushing embedding assembly includes:

[0045] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0046] It should be noted that, in the description of this utility model, unless otherwise stated, the terms "upper," "lower," etc., indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0047] Furthermore, the terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. "Vertical" is not vertical in the strict sense, but within the allowable error range.

[0048] Combination Figure 1 , Figure 2 as well as Figure 3 As shown, this utility model provides an automatic bushing embedding device, which includes a feeding mechanism 1 and a mechanical gripper 3. The feeding mechanism 1 includes a receiving plate 11 and a push rod cylinder 12, and the mechanical gripper 3 includes a mounting base plate 31, a bushing embedding component 32, and a product clamping component 33.

[0049] Specifically, the input end of the feeding mechanism 1 is connected to the vibratory feeder 2, which contains a large number of bushings 100 to be embedded. The receiving plate 11 in the feeding mechanism 1 has a bushing access channel extending radially along its first radial direction on its side. The receiving plate 11 has a bushing placement groove 13 extending radially through its interior, communicating with the bushing access channel. The first and second radial directions are perpendicular, and the receiving plate 11 receives the bushings 100 fed from the vibratory feeder 2. The output end of the push rod cylinder 12 can move radially to push the bushings 100 out of the bushing placement groove 13. The bushing embedding assembly 32 in the mechanical gripper 3 is located on the mounting base plate 31 near the receiving plate 11, and is used to cooperate with the push rod cylinder 12 to engage the bushings 100 and embed them into the mold. The product gripping component 33 in the mechanical gripper 3 is located on the side of the mounting base plate 31 away from the receiving plate 11, and is used to grip the product on which the bushing 100 is mounted. It is understood that the mechanical gripper 3 is mounted on a suitable robotic arm or moving device, enabling it to move flexibly between the feeding mechanism 1 and the mold.

[0050] In the automatic bushing embedding device provided by this utility model, the bushings 100 are automatically sorted by the vibratory feeder 2 and conveyed to the bushing access channel of the receiving plate 11, ensuring that the bushings 100 enter the receiving plate 11 along the first radial direction. The bushings 100 slide into the bushing placement groove 13 along the bushing access channel, so that the bushings 100 are in a state of waiting to be pushed. The mechanical gripper 3 moves to the output end of the feeding mechanism 1, so that the sleeve end of the bushing embedding component 32 is aligned with the bushing 100 pushed out into the bushing placement groove 13. The push rod cylinder 12 extends along the second radial direction, pushing the bushing 100 out of the bushing placement groove 13, so that it enters the sleeve position of the bushing embedding component 32 of the mechanical gripper 3, completing the automatic feeding of the bushings 100. Then, the mechanical gripper 3 carries the bushings 100 to the mold and embeds the bushings 100 into the mold. After the bushing 100 is embedded, the mechanical gripper 3 rotates or translates to align the product gripping component 33 with the processed product, clamps the product, removes it from the mold, and sends it to the next process, thus achieving continuous embedding and retrieval operations. After retrieval, the mechanical gripper 3 returns to its initial position, waiting for the next bushing 100 to be pushed and embedded. The above process is repeated to achieve continuous automated embedding of the bushing 100 until the production task is completed.

[0051] The automatic bushing embedding device provided by this utility model achieves automatic positioning and arrangement of bushings 100 through the bushing access channel and bushing placement groove 13 of the receiving plate 11, eliminating the need for manual intervention, significantly improving feeding efficiency, and avoiding the problem of missed installation caused by manual operation. The bushing embedding component 32 of the mechanical gripper 3 works in conjunction with the push rod cylinder 12 to ensure that the bushing 100 is accurately fitted onto the mechanical gripper 3 and embedded into the mold, reducing the steps of traditional manual or mechanical gripper 3 pre-installation of bushings 100, improving embedding accuracy and consistency, and reducing the risk of mold damage. The fully automatic operation mode eliminates the risk of burns from direct contact with the high-temperature mold, while reducing safety accidents caused by fatigue or operational errors, and improving production safety. The mechanical gripper 3 integrates the bushing embedding component 32 and the product clamping component 33, and can directly clamp the finished product after the bushing 100 embedding process is completed, optimizing the production cycle and improving overall efficiency. The receiving plate 11 adopts a vertically arranged bushing access channel and bushing placement groove 13, which optimizes the spatial layout, makes the overall structure compact, and facilitates docking with the vibratory feeder 2 and the mechanical gripper 3.

[0052] In summary, this automatic bushing embedding device solves the problems of low efficiency, poor safety, and high omission rate associated with traditional manual or semi-automatic embedding methods. It achieves automatic feeding, gripping, embedding, and clamping of bushings 100, with minimal manual intervention throughout the process, thus shortening the production cycle. Compared to traditional manual operation, it improves production efficiency and can meet the needs of large-scale production.

[0053] Furthermore, such as Figure 4 As shown, in order to ensure accurate positioning of the bushing 100 and avoid missing or misaligned installation, the feeding mechanism 1 may include a first bushing detection switch 14, which is set on one side of the bushing placement slot 13 to detect whether the bushing 100 is in place.

[0054] Combination Figure 3 , Figure 4 as well as Figure 5 As shown, in this utility model, the feeding mechanism 1 may also include a bushing flow channel 15 and a direct vibration feeder 16.

[0055] Specifically, one end of the bushing flow channel 15 is connected to the vibratory plate 2, and the other end is connected to the bushing inlet channel. The bushing 100 enters the bushing flow channel 15 from the outlet of the vibratory plate 2 and can smoothly transition to the bushing placement slot 13. The direct vibration feeder 16 is located between the vibratory plate 2 and the receiving plate 11 and is connected to the lower end of the bushing flow channel 15. Its driving device drives the bushing flow channel 15 to vibrate at high frequency and small amplitude, so that the bushing 100 moves forward at a uniform speed along the bushing flow channel 15, avoiding jamming or accumulation. The direct vibration feeder 16, in conjunction with the bushing flow channel 15, realizes the uniform, directional, and continuous conveying of the bushing 100.

[0056] Furthermore, in this invention, the bushing flow channel 15 is inclined downwards along the first radial direction. Its high end connects to the discharge port of the vibratory feeder 2, and its low end connects to the bushing access channel opened on the side of the receiving plate 11. It can be understood that its inclination angle is only required to ensure that the bushing 100 can slide naturally under gravity. Automatic sliding along the inclined direction under the action of gravity can reduce the dependence on the vibration force of the direct vibration feeder 16 and reduce energy consumption.

[0057] In some embodiments, the inner wall of the bushing channel 15 may be provided with guide ribs or a damping coating to prevent the bushing 100 from rolling back.

[0058] Furthermore, in this utility model, multiple bushing flow channels 15 and multiple bushing access channels are provided, with each bushing flow channel 15 corresponding to a different bushing access channel and distributed vertically.

[0059] It is understandable that multiple bushing channels 15 are arranged in parallel vertically, with each bushing channel 15 maintaining a certain distance in the vertical direction, forming a layered layout. Each bushing channel 15 is connected to an independent bushing inlet channel at its end. The vibrating plate 2 discharge port is equipped with a multi-channel distributor to evenly distribute the bushings 100 to each layer of bushing channels 15.

[0060] In some embodiments, each bushing access channel can be connected to a plurality of parallel and spaced bushing placement slots 13. For example, two bushing access channels that are distributed vertically can be connected to two bushing placement slots 13 respectively, for a total of four bushing placement slots 13.

[0061] By utilizing a three-dimensional spatial layout, the system can increase production capacity while ensuring stable transportation, making it suitable for the mass production needs of automotive parts.

[0062] In this utility model, combined with Figure 6 and Figure 7 As shown, the bushing embedding assembly 32 may include a bushing placement post 321, a gripper positioning post 322, a bushing pusher cylinder 323, a pusher 324, and a second bushing detection switch 325.

[0063] Specifically, one end of the bushing placement post 321 is mounted on the mounting base plate 31, and the other end is used to connect with the bushing placement groove 13 and fit the bushing 100; one end of the gripper positioning post 322 is mounted on the mounting base plate 31, and the other end is used to connect with the gripper positioning hole set on the receiving plate 11 or the mold positioning hole set on the mold, so as to realize the positioning of the mechanical gripper 3 and the feeding mechanism 1, and ensure that the other end of the bushing placement post 321 can accurately connect with the bushing placement groove 13. The bushing push plate cylinder 323 is mounted on the mounting base plate 31 and is used to drive the bushing 100 to be embedded in the mold; the push plate 324 is connected to the output end of the bushing push plate cylinder 323; the second bushing detection switch 325 is mounted on the mounting base plate 31, and the sensing end of the second bushing detection switch 325 passes through and extends out of the push plate 324, and is used to detect whether the bushing 100 is fitted on the bushing placement post 321.

[0064] Furthermore, the other end of the bushing placement post 321 and the other end of the gripper positioning post 322 both extend through and out of the push plate 324.

[0065] Furthermore, the bushing embedding assembly 32 also includes a push ring 326 connected to the push plate 324, the push ring 326 being movably sleeved on the other end of the bushing placement post 321.

[0066] In a specific implementation of the bushing embedding component 32, the other end of the gripper positioning post 322 first aligns with the gripper positioning hole on the receiving plate 11 to achieve positioning of the mechanical gripper 3 and the feeding mechanism 1, ensuring that the other end of the bushing placement post 321 can accurately align with the bushing placement groove 13. After the other end of the bushing placement post 321 aligns with the bushing placement groove 13, the second bushing detection switch 325 starts working to detect whether the bushing 100 is fitted onto the bushing placement post 321. If the bushing 100 is detected to be fitted, the mechanical gripper 3, driven by the robotic arm or moving device, moves the bushing placement post 321 with the bushing 100 fitted onto it to the vicinity of the mold. After the mechanical gripper 3 moves to the vicinity of the mold, the other end of the gripper positioning post 322 aligns with the mold positioning hole on the mold to achieve positioning of the mechanical gripper 3 and the mold. After accurate positioning, the control system issues a command, the bushing pusher cylinder 323 starts, and its output end pushes the pusher plate 324 forward. Since the push ring 326 is connected to the push plate 324 and movably sleeved on the other end of the bushing placement post 321, the push plate 324 moves, causing the push ring 326 to move forward together. The push ring 326 pushes the bushing 100 sleeved on the bushing placement post 321, pushing the bushing 100 out of the bushing placement post 321 and accurately embedding it into the designated position in the mold. After the bushing 100 is embedded in the mold, the bushing push plate cylinder 323 reverses its movement, causing the push plate 324 and the push ring 326 to return to their initial positions. The robotic arm or moving device drives the robotic gripper 3 to leave the mold, completing one bushing 100 embedding operation.

[0067] The dual positioning of the gripper positioning post 322 and the receiving plate 11 or the mold improves the positioning accuracy of the bushing 100 and avoids positional deviations caused by manual operation. The second bushing detection switch 325 detects the bushing 100's engagement status in real time to prevent omissions, and the buffering effect of the push ring 326 ensures that the bushing 100 is subjected to uniform force.

[0068] In some embodiments, multiple gripper positioning posts 322 may be provided, and the multiple gripper positioning posts 322 are evenly distributed on the mounting bottom.

[0069] In some embodiments, multiple bushing placement columns 321 may be provided, and the multiple bushing placement columns 321 correspond one-to-one with the multiple bushing placement slots 13.

[0070] In this utility model, the product gripping component 33 includes a gripper 331 and a gripper cylinder 332.

[0071] The gripper 331 is used to hold the product. The gripper cylinder 332 is located on one side of the mounting base plate 31. The output end of the gripper cylinder 332 is connected to the gripper 331 and is used to drive the gripper 331 to pick up the product.

[0072] In practical use, when the mechanical gripper 3 moves to the product clamping position, the product is ejected from the mold. The gripper cylinder 332 in the mechanical gripper 3 is activated, and the gripper 331 clamps the product and removes it. When the gripper moves directly above the product conveyor belt 6, the gripper cylinder 332 is activated again, and the product returns to its original state. The product automatically falls onto the product conveyor belt 6.

[0073] In some embodiments, the automatic bushing insertion device further includes a touch screen 7, which is mounted on the frame 4 and electrically connected to the control system for displaying production data, alarm information, etc.

[0074] Another aspect of this utility model provides an automatic bushing 100 embedding system, which includes a frame 4, the aforementioned automatic bushing embedding device, a vibratory feeder 2, a worktable 5, and a product conveyor belt 6.

[0075] Specifically, the automatic bushing embedding device is mounted on the frame 4, which can be configured as a cabinet to support and protect the automatic bushing embedding device; the vibratory feeder 2 is mounted on the frame 4 and connected to the feeding mechanism 1, used to automatically arrange the bushings 100 and transport them along the spiral track to the discharge port, ensuring that the bushings 100 are arranged in a uniform direction; the workbench 5 is located on one side of the frame 4 and is used for product packaging and appearance inspection; one end of the product conveyor belt 6 is mounted on the frame 4 and the other end extends above the workbench 5.

[0076] The automatic bushing 100 embedding system enables fully automated operation from bushing 100 feeding to product packaging and inspection, improving production efficiency and product qualification rate, ensuring quality consistency; reducing manual intervention, lowering labor intensity and product damage risk; and featuring a reasonable and compact layout with high space utilization.
