Description

Technical Field

[0001] This utility model relates to the field of PIN detection technology, specifically to an automatic PIN sorting and feeding device. Background Technology

[0002] As a key component in electronic connectors, integrated circuits, and other electronic devices, the uniformity of PIN pins in terms of size, shape, appearance, and electrical performance is crucial. During production, PIN pins undergo multiple inspection processes to separate qualified products, defective products, and products requiring re-inspection for further processing. The PIN pin unloading device is an automated piece of equipment that performs this sorting and physical classification, serving as a critical link between upstream inspection and downstream packaging or rework.

[0003] Currently, common PIN sorting and unloading methods mainly include manual sorting, mechanical lever unloading, and single airflow unloading, but all of them have problems: Relying on operator visual inspection or simple tools for judgment and sorting is labor-intensive, inefficient, and prone to missed inspections and misjudgments due to fatigue, resulting in poor sorting consistency and making it unsuitable for modern high-speed production lines. Using robotic arms or levers to push PIN pins out of carriers is another method. This method is structurally complex, requires extremely high positioning accuracy for the PIN pins, and is prone to scratching the PIN pin surface during the maneuver, potentially damaging precision PIN pins or those with plating. Airflow blowing off PIN pins is another method, but it typically only has one exit or a simple "pass / fail" two-way sorting, failing to meet the needs of a three-level classification of "pass, pending confirmation, and fail," resulting in limited functionality and flexibility.

[0004] In summary, the existing PIN feeding methods have drawbacks such as low sorting efficiency, easy physical damage to products, limited classification levels, and low levels of automation and intelligence, making it difficult to meet the demands of modern electronic manufacturing for high precision, high efficiency, and multiple product specifications.

[0014] 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.

[0015] See Figure 1 Combination Figure 2 The present invention provides a technical solution: an automatic PIN needle sorting and feeding device, including a workbench 1, a bearing disc 2, a motor, a clamp 3, a feeding mechanism 5, a gas cylinder 54, a feeding and sorting port 4, and a sorting box 6.

[0016] The carrier disc 2 is rotatably connected to the workbench 1. The carrier disc 2 is connected to the motor and drives the carrier disc 2 to rotate. Multiple equally spaced clamps 3 are provided on the outer ring of the upper surface of the carrier disc 2. The clamps 3 have triangular grooves 31, which are used to place PIN pins. A feeding mechanism 5 is horizontally arranged on the outer side of the carrier disc 2 and is installed on the workbench 1. The feeding mechanism 5 is fixed on the workbench 1 by a feeding mechanism bracket 511 and extends above the carrier disc 2. A connecting bracket 512 is fixed on the feeding mechanism bracket 511. An inverted T-shaped connecting block 513 is provided on the connecting bracket 512. A connecting plate 514 is connected to the lower surface of the inverted T-shaped connecting block 513. An air blowing fastener 515 is fixedly connected to the upper surface of the connecting plate 514.

[0017] The feeding mechanism 5 includes a solenoid valve 51, an air blowing pipe 52, an air blowing nozzle 53, and an air cylinder 54.

[0018] Gas cylinder 54 is located at the bottom of one side of workbench 1. The top of gas cylinder 54 is connected to solenoid valve 51. There are three solenoid valves 51. One end of air blowing pipe 52 is connected to the three solenoid valves 51 respectively. The other end of air blowing pipe 52 is provided with air blowing nozzle 53. Air blowing pipe 52 passes through air blowing fixture 515 and extends to the top of the bearing circle. Air blowing nozzle 53 is aligned parallel to the three clamps 3 respectively.

[0019] There are three sorting ports 4 between the feeding mechanism 5 and the carrying disc 2. The three sorting ports 4 are coaxially aligned with the air nozzle 53 and the clamp 3, respectively. The bottom of the sorting port 4 is provided with a feeding channel. The bottom of the workbench 1 is provided with a sorting box 6. The sorting box 6 is located at the bottom of the three sorting ports 4. The sorting box 6 is connected to the three sorting ports 4 through the feeding channel. The three sorting ports 4 are respectively the qualified product sorting port, the unconfirmed product sorting port, and the unqualified product sorting port.

[0020] An automatic PIN needle sorting and unloading device further includes a feeding mechanism and a detection mechanism. The feeding mechanism is used to place the PIN needles in the clamp 3. The motor drives the carrier disc 2 to rotate. The detection mechanism is set on the outer periphery of the carrier disc 2 and is used to detect the PIN needles. When the detected PIN needles rotate to the unloading mechanism 5, the unloading mechanism 5 automatically blows the PIN needles into the corresponding sorting port according to the detection results to complete the unloading and sorting operation in a fully automatic manner.

[0021] Working principle: The feeding mechanism places the PIN pins to be tested one by one into the clamp 3 on the outer ring of the carrier disc 2. The triangular groove 31 on the clamp 3 can stably limit the PIN pins, preventing them from shifting or falling during the rotation of the disc, thus providing a stable bearing base for subsequent testing and sorting.

[0022] During the transfer and testing phase, the motor drives the carrier disc 2 to rotate at a constant speed, which in turn drives the clamp 3 containing the PIN pins to pass through the testing mechanism in sequence. The testing mechanism performs a comprehensive test on the PIN pins and transmits the test results to the device control system in real time. The system will classify the PIN pins into three categories according to the preset standards: qualified products, products to be confirmed, and unqualified products.

[0023] During the sorting and unloading stage, when the carrier disc 2 transfers the completed PIN needles to the corresponding station of the unloading mechanism 5, the control system will trigger the corresponding solenoid valve 51 according to the detection result. The compressed gas in the gas cylinder 54 enters the air blowing pipe 52 through the solenoid valve 51, and then the airflow is ejected from the air blowing nozzle 53, which is coaxially aligned with the fixture 3. If it is a qualified product, the control system activates the solenoid valve 51 of the corresponding qualified product sorting port, and the airflow blows the PIN needle into the qualified product unloading sorting port 4, and it falls into the qualified product storage area of ​​the sorting box 6 through the unloading channel. If the item is determined to be an item to be confirmed, the airflow will blow it into the confirmation unloading and sorting port 4 and into the confirmation area of ​​the sorting box 6, which will facilitate subsequent manual re-inspection.

[0024] If the product is defective, the corresponding defective product sorting port solenoid valve 51 will be activated, and the PIN needle will be blown into the defective product unloading sorting port 4, and finally collected into the defective product area of ​​the sorting box 6.

[0025] The cyclic operation carrying disc 2 rotates continuously, and the empty fixture 3 will return to the feeding mechanism station to enter the next round of feeding, inspection and sorting cycle, thereby realizing the continuous and automated screening and unloading of PIN pins.
