Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, in particular to an automatic feeding device for metal pins. Background Art

[0002] In the electronic components and precision manufacturing industries, metal pins are widely used in the assembly of components for motor stators, connectors, PCB boards, and other products. With increasing demands for product quality and production efficiency, traditional manual pin insertion methods can no longer meet the high-precision and high-efficiency production needs. Existing pin insertion processes mostly rely on manual operation or use semi-automatic assembly equipment, which presents the following problems:

[0003] High manual operation costs: In traditional pin insertion processes, manual assembly is not only time-consuming and labor-intensive, but also requires a large number of skilled workers. Due to operator fatigue and individual differences, manual assembly quality is unstable and prone to problems such as misalignment and missing insertions, which is not conducive to the stable control of product quality.

[0004] Insufficient precision and consistency: Manual pin insertion has relatively low precision and consistency, especially for pins in tiny, delicate components. Manual operation often struggles to meet high-precision assembly requirements. While semi-automatic equipment can improve assembly efficiency to a certain extent, it still lacks positioning accuracy and consistency.

[0005] Low efficiency and high error rate: Manual and semi-automatic pin insertion are inefficient, especially in scenarios requiring large-scale production. Manual pin insertion efficiency is insufficient to meet the demands of rapid production. Furthermore, manual operation is prone to errors, leading to increased product rejection rates.

There is a lot of manual intervention and the degree of automation is low, which cannot meet the needs of intelligent production.

[0007] Therefore, it is very necessary to invent a kind of metal pin automatic feeding equipment. Utility Model Content

[0029] Compared with the existing technology, this metal pin automatic feeding equipment has the following advantages:

[0030] 1. High degree of automation: This equipment completes all the processes from pin feeding, rotation conversion, grabbing and transportation to precise pin insertion through automated processes, which reduces manual intervention and improves production efficiency.

[0031] 2. Precise pin positioning: The needle grabbing structure 4 cooperates with the multi-directional movable track, the clamping movable track 42 and the lateral movable track 44 to realize the multi-directional precise movement of the pin, so that the pin can be accurately positioned in the pin placement fixture 6, thereby improving the accuracy of the pin insertion operation and reducing errors.

[0036] In summary, this equipment achieves high efficiency, precision and automation of the pin assembly process through multi-functional integration and precision design. Compared with traditional manual or semi-automatic equipment, it has significant advantages in efficiency, quality and stability.

[0037] The working principle of the metal pin automatic feeding equipment mainly includes the process of feeding, rotating conversion, grabbing and transporting, and precise positioning of the pins. The following is its detailed working principle:

[0038] 1. Horizontal feeding of pins: First, the pins are horizontally input into the rotating mechanism 2 through the feeding station 3, and the rotating mechanism 2 is responsible for receiving the pins.

[0039] 2. Rotation conversion: When the pin enters the rotating mechanism 2, the rotating mechanism 2 starts working and rotates the pin from a horizontal state to a vertical state. This process ensures that the pin is in a suitable vertical position when it is grasped by the needle grasping mechanism 4, so as to facilitate subsequent precise operation.

[0040] 3. Pin Grasping Mechanism: After the pin is vertically positioned, the pin grabbing mechanism 4, located behind the rotating mechanism 2, begins its grasping operation. The grasping mechanism 4 consists of a pneumatic gripper 45, a gripping track 42, and a transverse track 44. During the grasping process, the pneumatic gripper 45, through the coordination of the gripping track 42 and the transverse track 44, achieves multi-directional movement and precisely grasps the pin.

[0041] 4. Pin handling: After the pin is clamped by the pin grasping structure 4, it is moved along the conveying track 5 to the pin placement fixture 6. The pin grasping structure 4 ensures the stability of the pin and accurately places it in the pin placement fixture 6 to meet the requirements of subsequent processes.

[0042] 5. Auxiliary feeding at the stator feeding station: Simultaneously with the pin insertion and feeding, the stator feeding station 8 also performs synchronous feeding. The stator slides along the feeding track 82 to the feeding slide 83, where it is pushed to the designated position by the cylinder 84. The positioning posts on the stator fixture 85 mate with the positioning holes below the needle transfer mechanism 7, ensuring the stability of the stator in the feeding position.

[0043] 6. Pin Assembly: Once the pin reaches the pin placement jig 6, the pin transfer mechanism 7 further precisely positions the pin, completing the pin-stator assembly. The cylinder 84 on the stator jig 85 pushes the stator out, facilitating the pin's entry into the stator and ensuring pin-stator assembly accuracy.

[0044] 7. Reciprocating Cycle: When one pin is assembled, the machine automatically returns to its initial state to begin feeding, picking, and assembling the next round of pins. The entire process is managed by an automatic control system, ensuring efficient and continuous operation of the feeding, conversion, picking, handling, and assembly processes.

[0045] Through the above steps, the equipment realizes a fully automated process from pin feeding to precise pin assembly. It has efficient and precise operating characteristics and can greatly improve the production efficiency and quality of metal pin assembly.

[0046] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
