Description

Technical Field

[0001] This utility model relates to an online detection mechanism for the pin height of a connector. Background Technology

[0002] Automotive printed circuit board connectors are a common type of connector used in automotive electronics engineering for signal and power interconnection applications. These connectors offer excellent performance in low-voltage differential signaling and embedded applications. As demands for safety, environmental friendliness, comfort, and intelligence in automobiles increase, the application of automotive electronic products is also growing, placing higher demands on connector quality. Because the production of these connectors involves multiple processes such as stamping pins, electroplating pins, injection molding, and assembly, the process chain is relatively long. This can lead to inconsistencies in pin height on the product, affecting its performance.

[0003] Current inspection methods involve manual sampling, using height gauges to measure relevant data, and then manually determining whether it meets the tolerance requirements of the drawings. This method is not only inefficient and prone to human error, but also limited to sampling, resulting in delayed feedback and disruptions to normal production, easily leading to batch defects. Such problems could result in vehicle recalls, posing significant quality risks during the production process.

[0004] Therefore, an online detection mechanism for connector pin height is proposed to address the above issues. Utility Model Content

[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] like Figure 1-4 As shown, an online detection mechanism for the pin height of a connector includes a product positioning fixture, a detection component, a pushing component, and a photoelectric sensing component. The product positioning fixture is set at the detection station 10 for positioning the product to be inspected on the production line. The detection component is set above the detection station 10, the pushing component is connected above the detection component, and photoelectric sensing components are connected to both sides of the detection component for determining whether the detection is qualified.

[0016] Specifically, the product positioning fixture includes a connector 100, and pins 101 on the connector 100 for connecting to the connector to be tested.

[0017] Specifically, the detection assembly includes a mechanism fixing plate 3, a spring pressure plate 4, multiple springs 5, multiple push rods 6, and a push rod mounting plate 7. The push rod mounting plate 7 is connected to the side wall of the mechanism fixing plate 3. Multiple push rod insertion holes are opened on the push rod mounting plate 7. Each of the multiple push rods 6 is inserted into its corresponding push rod insertion hole. The stepped surface of each push rod 6 sits on the upper end surface of the push rod mounting plate 7. Each push rod 6 has a light-transmitting hole at a suitable height to allow the light signal of the photoelectric sensing component to pass through. Each of the multiple springs 5 ​​is installed in the spring hole of its corresponding push rod 6. The other end of each spring 5 is installed in the multiple spring holes of the spring pressure plate 4 to realize the reset and rebound function of the push rod 6.

[0018] Specifically, the driving component includes a cylinder mounting bracket 2 and a cylinder 1. The cylinder 1 is connected to the cylinder mounting bracket 2, and the end of the piston rod of the cylinder 1 is connected to the center of the top surface of the mechanism mounting plate 3 to realize the reciprocating motion of the detection component. Using a cylinder for driving makes installation, debugging, and maintenance convenient.

[0019] Specifically, the photoelectric sensing component includes a photoelectric transmitter 8 and a photoelectric receiver 9. The photoelectric transmitter 8 and the photoelectric receiver 9 are respectively installed on both sides of the top rod mounting plate 7, and the installation height is consistent with the height of the light-transmitting hole opened on the top rod 6 after rebound.

[0020] Specifically, the connector 100 is first positioned on the testing station 10. Under the control of the equipment PLC system, the cylinder 1 of the push component drives the testing component to contact the connector 100. The push rod 6 in the testing component contacts the connector pin 101 and then retracts. When the height of the connector pin 101 is qualified, the light beam emitted by the photoelectric emitter 8 of the photoelectric sensing component can be received by the photoelectric receiver 9 through the light-transmitting hole of the push rod 6, and an OK signal is transmitted to the PLC. When the height of the connector pin 101 is unqualified, the light beam emitted by the photoelectric emitter 8 of the photoelectric sensing component cannot be received by the photoelectric receiver 9 through the light-transmitting hole of the push rod 6, and an NG signal is transmitted to the PLC, thereby realizing the detection function of the connector pin height.

[0021] The online detection mechanism for the pin height of this connector is configured with a product positioning fixture, a detection component, a pushing component, and a photoelectric sensing component. The product positioning fixture is located at the detection station 10 and is used to position the product to be inspected on the production line. The detection component is located above the detection station 10, and the pushing component is connected above the detection component. Photoelectric sensing components are connected to both sides of the detection component to determine whether the detection is qualified. This mechanism facilitates detection and saves time and effort.
