Description

Technical Field

[0001] This invention relates to the field of embedded part feeding technology, specifically to an orderly feeding device for embedded parts of injection molded products. Background Technology

[0002] In the automated production process of injection molded products, it is often necessary to pre-position and send various embedded parts into the mold cavity before injection molding. Traditional production often uses manual placement of embedded parts, which is not only labor-intensive and inefficient, but also prone to problems such as misalignment, omission, and reversed orientation of embedded parts, seriously affecting the yield rate and production stability of injection molded products.

[0003] With increasing automation, the industry is gradually adopting single robotic arms to pick up embedded parts one by one for loading. However, this method can only process a small number of embedded parts at a time. When dealing with multiple specifications and quantities of embedded parts, the cycle time is too long and the efficiency is low, which cannot meet the needs of high-speed production lines. If multiple robotic arms are used to work together, it will be limited by the size of the injection molded product and the equipment layout space. Interference between robotic arms is easy to occur, and the overall structure is complex, costly, and difficult to debug.

[0004] Meanwhile, existing embedded part feeding equipment generally suffers from unstable material distribution, easily leading to phenomena such as material stacking, jamming, and blockage, and poor consistency in the feeding position of embedded parts. Some equipment uses a fixed overall support fixture, which cannot be adapted to synchronous feeding with dual handling mechanisms, limiting operating space; if a segmented assembly line feeding method is adopted, it will significantly increase the equipment footprint (because the molding, cooling, and inspection processes of injection molded parts require a lot of space, and if the space is not used rationally, only a small number of production lines can be placed in the same factory area), increasing manufacturing and operating costs. To address this, we propose an orderly feeding equipment for embedded parts of injection molded products. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Multi-mechanism collaborative feeding enables simultaneous handling of multiple embedded parts, adapting to the production needs of complex injection molded products. Three primary feeding mechanisms and one secondary feeding mechanism are set up, corresponding to the automatic sorting and distribution of embedded parts of different specifications. Combined with the synchronous transport of the primary and secondary handling mechanisms, multiple embedded parts can be fed at once, significantly improving pre-injection molding feeding efficiency and solving the problem of low efficiency in traditional manual or single-station feeding. A combination of mobile and fixed support fixtures is used. If a single support fixture is used, it cannot accommodate the simultaneous operation of two handling mechanisms due to insufficient operating space; however, a production line-style operation would significantly increase the space occupied and raise equipment production costs.

[0017] 2. The material separation structure is adopted to achieve precise single-piece material distribution, eliminating material stacking, jamming, and blockage. The first material feeding mechanism realizes the directional conveying of the embedded parts through the circular vibration component and the linear vibration component. In conjunction with the first push-pull cylinder driving the material separation plate, the single embedded part is accurately sent into the material position slot and the subsequent embedded parts are blocked. Then, the lifting cylinder and the ejector pin lift the embedded part to the gripping position. The whole process is stable and reliable, significantly improving the feeding accuracy.

[0018] 3. The supporting fixtures can be combined and docked to meet the positioning requirements of embedded parts in large-size injection molded products. The moving and fixed supporting fixtures can be precisely docked through servo linear module drive to form a complete support structure for injection molded products. This overcomes the limitations of traditional fixed fixtures that cannot adapt to large-size, multi-embedded-point injection molded parts, ensuring complete positioning surfaces and high positional consistency. Two handling mechanisms can be used with minimal increase in space, significantly improving processing efficiency.

[0019] 4. The support mechanism is adjustable, ensuring strong equipment compatibility and versatility. The adjustable support fixture is driven by a second push-pull cylinder to move the third moving seat along the second linear guide rail. Its position can be adjusted according to the embedding position of different injection molded products. Together with the fourth and fifth support pins, it can achieve precise lifting. It can be adapted to multiple product models without changing the fixture, reducing equipment modification costs.

[0020] 5. The dual-transfer mechanism with multiple grippers operates synchronously, resulting in high transfer efficiency and accurate positioning. The first and second transfer mechanisms are equipped with multiple sets of dedicated grippers, which can simultaneously grab embedded parts of various specifications and deliver them to the mobile support fixture, fixed support fixture, and adjustable support fixture, respectively. This reduces the number of times the robotic arm travels back and forth, resulting in a faster operating rhythm. Combined with the guide structure, it achieves precise placement.

[0021] 6. The support needle has a limiting structure, ensuring stable placement of the embedded part without shifting or falling off. The movable, fixed, and adjustable support fixtures all use support needles to lift the embedded part. The top of the needle has a limiting step to firmly hold the embedded part, preventing slippage and tilting during handling and docking, effectively improving the yield rate of injection-molded embedded parts.

[0022] 7. The grippers feature a contoured arc-shaped structure design, ensuring secure clamping without damaging the embedded part. The first, second, third, and fourth grippers are all designed with a specific ratio of arc-shaped grooves and protrusions, perfectly matching the shape and height of the embedded part. This ensures even clamping force, preventing damage and deformation, and guaranteeing the appearance and dimensional accuracy of the embedded part. The grooves and protrusions are set according to a specific radius ratio, which evenly distributes the clamping force of the clamping cylinder, avoiding localized stress concentration and preventing damage such as indentations, deformation, or pinching to the embedded part. This maintains the dimensional accuracy and appearance integrity of the embedded part, improving the yield rate of injection molded products. The combination of arc-shaped grooves and protrusions has a self-centering function; when the grippers close, they automatically correct the embedded part to the center position, reducing the alignment accuracy requirements of the material feeding mechanism, minimizing jamming and gripping failures, and improving the equipment's fault tolerance.

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0026] Please see Figure 1 In this embodiment of the invention, an injection molding product embedded part orderly arrangement feeding device includes a frame 1. A movable support fixture 3, a fixed support fixture 4, an adjustable support fixture 5, and a second material feeding mechanism 6 are sequentially installed on the top of the frame 1. Three first material feeding mechanisms 2 are sequentially installed behind the movable support fixture 3, the fixed support fixture 4, and the adjustable support fixture 5. The frame 1 is also equipped with a first conveying mechanism 7 and a second conveying mechanism 8 for feeding materials. The second material feeding mechanism 6 and the three first material feeding mechanisms 2 are respectively used for... The same applies to the loading and distribution of embedded parts; the first transport mechanism 7 is used to transport the embedded parts on two adjacent first distribution and loading mechanisms 2 to the movable support fixture 3; the first transport mechanism 7 is used to transport the embedded parts on another first distribution and loading mechanism 2 to the fixed support fixture 4, and the first transport mechanism 7 (that is, the first transport mechanism 7 near the second distribution and loading mechanism 6) is also used to transport the embedded parts of the second distribution and loading mechanism 6 to the adjustable support fixture 5; the movable support fixture 3 and the fixed support fixture 4 are connected to form a support fixture for the complete injection molded product.

[0027] like Figure 1 , 23. The first material feeding mechanism 2 includes a circular vibration component 201, a linear vibration component 202, and a support 203.

The circular vibration assembly 201 orients and sorts the embedded parts, then feeds them into the linear vibration assembly 202; the linear vibration assembly 202 conveys the embedded parts forward to the misalignment plate 205; when the embedded part at the misalignment groove 210 of the misalignment plate 205 enters the material level groove 208 of the baffle plate 209, the first push-pull cylinder 204 drives the misalignment plate 205 to move, so that the misalignment groove 210 and the material level groove 208 are not aligned, thus avoiding the embedded part at the misalignment groove 210 of the misalignment plate 205 from affecting the embedded part at the material level groove 208 (because if there is no misalignment, the position of the embedded part in the misalignment groove 210 will be affected during the lifting), and a single embedded part is accepted; the lifting cylinder 206 drives the ejector pin 207 to rise, lifting the embedded part to the grabbing height, waiting for the material to be picked up; the alignment sensor detects the position status of the embedded part to ensure accurate feeding.

The first transport mechanism 7 and the second transport mechanism 8 operate sequentially. The first clamping cylinder 701 drives the first gripper 702, and the second clamping cylinder 703 drives the second gripper 704 to complete the gripping of the embedded part.
